Detailed Description

Electronic devices such as laptop computers, tablet handsets, convertible devices, and other types of computing devices may include a display. The electronic device may include a rotatable member for viewing the display at various angles. As used herein, the term "display" may, for example, refer to a device that may provide information to a user and/or receive information from a user. For example, the display may include a Graphical User Interface (GUI) that may provide information to and/or receive information from a user.

The electronic device may include a rotatable component, such as a rotatable display, which may also include a hinge. For example, facilitating rotation of the rotatable member to allow viewing of the display at various angles may be accomplished with a hinge. As used herein, the term "hinge" may, for example, refer to a mechanical connection that connects two objects such that the two objects may rotate relative to each other about a fixed axis of rotation through a rotational angle. For example, a display of a computing device may be rotated such that the display may be viewed at various angles.

In some approaches, a device including a touch screen display may experience a force in response to a user input to the display. For example, a user may touch a display to provide input to a computing device, and the display may experience a force as a result of the user touching the display. The display may be rotated by a rotation angle due to a user touching the display. In some examples, rotation of the display due to a user touching the display may cause the display to rotate to an angle that may not be desirable to the user. Thus, the user may have to rotate the display back to the angle desired by the user. In some examples, to prevent the display from rotating, the user may not touch the display with force to cause input to the display to be received by the display, resulting in the display not receiving input.

In contrast, examples herein allow for a variable torque lever that may allow for varying the torque to be applied to the display to resist the force applied to the display by the user. In some examples, this may allow the display to maintain a desired angle while the user interacts with the display and/or may mitigate damage to the display that may result if the display is allowed to rotate to an angle greater than a particular threshold angle.

The present disclosure relates to an apparatus. In some examples, the device may include a hinge. The device may include a variable torque lever that may provide a varying torque when the device is operated. In various examples according to the present disclosure, a device with variable torque may resist rotation when a user touches the display. By resisting rotation, the device can maintain the angle desired by the user. In some examples, the variable torque may be weaker when the user is opening the computing device to view the display, such that the user may open the computing device with one hand. In other examples, the variable torque may increase as the angle between the display and the housing of the computing device increases, which may prevent the display from experiencing touch forces that may damage the computing device. The term "touch force" as used herein refers to the amount of force applied to move a display of a computing device and/or to apply an input to the computing device through physical touch.

Fig. 1A, 1B, and 1C illustrate side views of an exemplary device 100 according to the present disclosure. The device 100 may include a first bracket 102, a first shaft 104, a second bracket 106, a variable torque rod 108, a second shaft 110, a plurality of notches 112-1.. 112-N, and a tensioner mechanism 114. Although fig. 1A, 1B, and 1C are shown as having three notches 112-1, 112-2.. 112-N, it should be understood that the variable torque rod 108 may have more or less than three notches.

As shown in fig. 1A, 1B, and 1C, the apparatus 100 may be oriented in an x-z coordinate plane. For example, the x-coordinate as shown in fig. 1A, 1B, and 1C may be a length, and the z-coordinate as shown in fig. 1A, 1B, and 1C may be a height. As shown in the coordinate planes shown in fig. 1A, 1B, and 1C, the positive x-direction may refer to a direction toward the right side of the page, and the positive z-direction may refer to a direction toward the top of the page. The negative x-direction may refer to a direction toward the left side of the page, and the negative z-direction may refer to a direction toward the bottom of the page.

As shown in fig. 1A, device 100 shows the device at a first angle of rotation. As shown in fig. 1B, device 100 shows the device at a second angle of rotation. As shown in fig. 1C, device 100 shows the device at a third angle of rotation. The device 100 rotates about the first axis 104 in a clockwise direction as shown in fig. 1A, 1B, and 1C from a first angle of rotation shown in fig. 1A, to a second angle of rotation shown in fig. 1B, to a third angle of rotation shown in fig. 1C. As used herein, the terms "angle of rotation" and/or "angle of rotation" refer to an angle formed by two reference rays, where the reference rays share a common endpoint, and movement of the reference rays about a longitudinal axis changes the figure.

The apparatus 100 may include a first support 102. As used herein, the term "stand" may, for example, refer to a support object for connecting to and/or supporting a different object. The first bracket 102 may be connected to a first shaft 104. As used herein, the term "shaft" may, for example, refer to a substantially cylindrical object, such as a pile or other structural member. The first support 102 may be connected to a rotating element of the computing device, such as a display of the computing device, as further described herein in connection with fig. 4.

The apparatus 100 may include a second bracket 106. The second bracket 106 may be connected to the first bracket 102. The second bracket 106 may remain stationary while the first bracket 102 and the first shaft 104 rotate. For example, the first bracket 102 and the first shaft 104 may rotate relative to the second bracket 106. The second bracket 106 may be connected to a housing of the computing device, as further described herein in connection with fig. 4.

The device 100 may include a variable torque rod 108 attached to the first bracket 102 via a second shaft 110. As used herein, the term "variable torque lever" may, for example, refer to a lever that is used to change the amount of torque applied when the lever is actuated by a device, machine, and/or apparatus, and the term "lever" as used herein is a mechanical and/or structural member. The variable torque rod 108 may be a rod having a shape that allows a variable torque to be applied to the first bracket 102 as the first bracket 102 increases in angle relative to the second bracket 106. For example, as shown in fig. 1A, 1B, and 1C, the variable torque rod 108 may move in a substantially negative x-direction in response to movement of the first support 102 in a substantially positive z-direction. The substantially negative z-direction may also be substantially orthogonal to the first longitudinal axis of the first shaft. The second shaft 110 may rotate about the second longitudinal axis in response to movement of the first support 102 as described above.

As used herein, the term "substantially" may be absolute, or may mean that the property is not always absolute, but is close enough to achieve the result of the property. For example, "substantially orthogonal" is not limited to absolute orthogonality, and may include orientations that are intended to be orthogonal, but may not be precisely orthogonal due to manufacturing limitations. For example, a "substantially negative direction" feature is oriented at least closer to a negative direction than a positive direction. Similarly, a "substantially positive direction" feature is oriented at least closer to a positive direction than a negative direction.

In some examples, the variable torque rod 108 may be tapered, asymmetric, and/or have a consistent shape and diameter. For example, the variable torque rod may have a varying width and may be extendable. In some examples, as described further below, the variable torque rod 108 may have notches, dimples, and/or depressions that correspond to particular angles formed by the first bracket 102 relative to the second bracket 106.

Variable torque rod 108 may include notches 112-1.. 112-N. As used herein, the term "notch" may, for example, refer to a portion of the variable torque rod 108 that may be formed by the variable torque rod 108, and/or may be an attachment to the variable torque rod 108. The notch (es) may correspond to a plurality of angles formed by the first bracket 102 relative to the second bracket 106. Notches 112-1.. 112-N may have varying sizes and/or diameters to facilitate the application of varying torques due to an increase or decrease in the angle between first bracket 102 and second bracket 106. Although fig. 1A, 1B, and 1C illustrate recesses having the same particular shape and size, it should be understood that the examples are not limited thereto. For example, while fig. 1A, 1B, and 1C are shown with three notches, it should be understood that the variable torque rod 108 may have more or less than three notches, and/or the notches may differ in size and shape. For example, notch 112-1 may have the same or different width and/or shape as notch 112-N.

The device 100 may include a tensioner mechanism 114. As used herein, the term "tensioner mechanism" refers to a member that applies pressure and/or resistance to a structural member. For example, the tensioner mechanism 114 may be a variety of springs. In some examples, the tensioner mechanism 114 may be a torsion spring, but examples are not limited thereto. In some examples, the tensioner mechanism may apply pressure and/or resistance to a structural member, such as the variable torque rod 108. In the example shown in fig. 1A, 1B, and 1C, the tensioner mechanism 114 is a spring that operates by twisting and/or twisting coils about substantially the same axis as the second longitudinal axis of the second shaft 110. The term "coil" as used herein may refer to a piece of spring that is manipulated into a substantially helical arrangement.

In the example shown in fig. 1A, 1B, and 1C, the tensioner mechanism 114 may have a pair of torque engagement pins 116-1, 116-2 that cause twisting/twisting of the coils when the pair of torque engagement pins 116-1, 116-2 are disengaged from each other. In other words, when the pair of torque engagement pins 116-1, 116-2 of the tensioner mechanism 114 are forced away from each other in the z-plane, the coils opposite the pair of torque engagement pins 116-1, 116-2 twist, thereby applying an increasing force in the form of torque to the variable torque rod 108 and the first bracket 102.

In some examples, the tensioner mechanism 114 may be anchored at an end opposite the pair of torque engagement pins 116-1, 116-2. As used herein, the term "anchor" refers to a portion that may be removably and/or removably secured to a portion of a structural member. For example, the spring portion opposite the pair of torque engagement pins 116-1, 116-2 may be anchored such that the tensioner mechanism 114 is substantially stationary with respect to the x-plane, but the pair of torque engagement pins 116-1, 116-2 may be free to move in the z-plane.

The pair of torque engagement pins 116-1, 116-2 may substantially correspond to notches 112-1.. 112-N, thereby slightly relieving the pressure/resistance experienced by tensioner mechanism 114 by allowing the pair of torque engagement pins 116-1, 116-2 to move closer to one another when located at notches 112-1.. 112-N. For example, the variable torque rod 108 may move in a substantially negative x-direction in response to changing the angle between the first bracket 102 and the second bracket 106. When the variable torque rod 108 moves in the negative x-direction, the tensioner mechanism 114 may experience tension in the form of torque around its coil in response to the pair of torque engagement pins 116-1, 116-2 disengaging from one another to accommodate movement of the variable torque rod 108, which increases torque as the pair of torque engagement pins 116-1, 116-2 move from notch 112-1 toward notch 112-2 as shown in fig. 1A and 1B.

In some examples, notches 112-1 …, 112-N engage tensioner mechanism 114 in various positions corresponding to the particular angle achieved by first bracket 102 relative to second bracket 106. For example, as shown in FIG. 1A, notch 112-1 may correspond to a 0 degree angle between brackets 102 and 106. In other words, notch 112-1 may correspond to first bracket 102 and second bracket 106 having an angle of about 0 degrees therebetween, as shown in FIG. 1A. As used herein, the term "about" when referring to degrees of angle means plus or minus 10 degrees. For example, the first stand 102 may be connected to a display of a computing device, such as a laptop computer, and the second stand 106 may be connected to a housing of the computing device, and when the computing device is closed, the angle between the display and the housing is about 0 degrees.

As shown in fig. 1A, the device 100 is in a first position corresponding to an angle of about 0 degrees between the first bracket 102 and the second bracket 106. As shown in fig. 1B, the device 100 is shown in a second position corresponding to about 90 degrees. As shown in fig. 1B, the variable torque rod 108 may move relative to the tensioner mechanism 114 to a second position at the notch 112-2 when the second shaft 110 rotates about a second longitudinal axis of the second shaft 110 corresponding to rotation about the first longitudinal axis of the first shaft 104 in response to an increase in the angle between the first bracket 102 and the second bracket 106. For example, as shown in fig. 1A, the first bracket 102 and the first shaft 104 may rotate to cause the second shaft 110 to rotate, thereby causing the variable torque rod 108 to move in a translational motion in the negative x-direction. When the pair of torque engagement pins 116-1, 116-2 of the tensioner mechanism 114 reach the notch 112-2 of the variable torque rod 108, the variable torque rod 108 may translate to a second position, as shown in FIG. 1B.

The first bracket 102 and the first shaft 104 may rotate relative to the second bracket 106 about a first longitudinal axis of the first shaft 104. For example, as shown in fig. 1A, the first bracket 102 and the first shaft 104 may be rotated from a first angle of rotation to a second angle of rotation as shown in fig. 1B by the first bracket 102 and the first shaft 104. The second bracket 106 may remain in the same position as the first bracket 102 and the first shaft 104 rotate, as shown in fig. 1A and 1B.

As shown in fig. 1A, 1B, and 1C, the variable torque rod 108 may be movable in a substantially orthogonal direction (e.g., a negative x-direction) relative to the first longitudinal axis of the first shaft 104. In some examples, the variable torque rod 108 may also tilt in the positive z-direction. For example, as shown in fig. 1B, the end of the variable torque rod 108 closest to the second shaft 110 may tilt in the positive z-direction as the angle between 102 and 106 increases.

As described above, a variable torque force may be generated between the variable torque rod 108 and the tensioner mechanism 114. For example, as shown in fig. 1A, when the variable torque rod 108 is in a first position, such as when a pair of torque engagement pins are in notches 112-1, a first torque force may be generated between the variable torque rod 108 and the tensioner mechanism 114. As shown in fig. 1B, in response to rotation of first bracket 102 and first shaft 104, variable torque rod 108 may be moved to a second position relative to tensioner mechanism 114, such as when a pair of torque engagement pins are in notches 112-2.

In some examples, the variable torque force may be greater at the second position (e.g., when notch 112-2 is engaged) than at the first position (e.g., when notch 112-1 is engaged). For example, as shown in fig. 1B, the torque force generated between the variable torque rod 108 and the tensioner mechanism 114 (e.g., when the variable torque rod 108 is in the second position) may be greater than the torque force generated between the variable torque rod 108 and the tensioner mechanism 114 (e.g., when the variable torque rod 108 is in the first position), as shown in fig. 1A. In some examples, this may allow for easier operation by the user.

For example, as shown in fig. 1A, when the first bracket 102 is connected to a display of a computing device, such as a laptop computer, and the second bracket 106 can be connected to a housing of the computing device, the notch 112-1 corresponds to a first position of approximately a 0 degree angle when the display of the computing device is closed. In some examples, as shown in fig. 1B, the variable torque rod 108 may be moved to the second position as described above, however, the torque force from the first position to the second position allows the user to easily open the computing device. In some examples, a weaker torque force applied from the first position shown in fig. 1A to the second position shown in fig. 1B may allow a user to use one hand to open the computing device.

In comparison, some methods may utilize two hands or another mechanism to open the computing device. For example, a user may utilize two hands, one hand for holding the housing of the computing device stationary, and the other hand holding the display and opening the computing device to a desired viewing angle. In another example, the user may utilize another mechanism to hold the housing of the computing device stationary while opening the display.

In response to the torque force at the second position shown in fig. 1B being greater than the torque force at the first position shown in fig. 1A, a greater force may be used than the torque force used to rotate the first bracket 102 shown in fig. 1A in order to produce an amount of torque to rotate the first bracket 102 shown in fig. 1B. For example, the first angle of rotation shown in fig. 1A may be about 0 degrees, as shown for first bracket 102 relative to second bracket 106. As shown in fig. 1B, the second angle of rotation may be about 90 degrees between the first bracket 102 relative to the second bracket 106. Since the torque force at the second position of the variable torque lever 108 is greater than the torque force at the first position of the variable torque lever 108, a greater force may be used at the second angle of rotation than the force used at the first angle of rotation to cause the first bracket 102 to rotate in order to cause the first bracket 102 to rotate.

In some examples, the greater torque force may prevent the display of the computing device from rotating when the user touches the display. Rotation by the device 100 against the display may allow the display to be held at a particular angle while providing input to the display via physical touch. For example, if a user is applying input to the computing device using the touchscreen feature, the user input by touch may not move the display from a desired angle due to the greater torque force at the second location.

In another example, fig. 1C shows the apparatus 100 at a third position corresponding to a third angle of rotation. The first and second rotation angles are discussed above in fig. 1A and 1B. The device 100 is rotated about the first axis 104 in a clockwise direction from the first angle of rotation and/or the second angle of rotation discussed above in fig. 1A and 1B to a third angle of rotation, as shown in fig. 1C.

In some examples, the notches 112-1.. 112-N may engage the tensioner mechanism 114 in various positions corresponding to particular angles achieved by the first bracket 102 relative to the second bracket 106. For example, notch 112-1 may correspond to an angle of about 0 degrees, as shown in FIG. 1A. In other words, notch 112-1 may correspond to first bracket 102 and second bracket 106 having an angle of about 0 degrees. In another example, the notch 112-2 may correspond to the first bracket 102 and the second bracket 106 having an angle of about 90 degrees, as shown above in fig. 1B. In another example shown in fig. 1C, notch 112-N may correspond to an angle of about 135 degrees between first bracket 102 and second bracket 106.

As shown in fig. 1C, the apparatus 100 is shown in a third position corresponding to an angle of about 135 degrees between the first bracket 102 and the second bracket 106. When the pair of torque engagement pins 116-1, 116-2 move into the notch 112-N in response to the variable torque rod 108 rotating about the second longitudinal axis of the second shaft 110, the variable torque rod 108 may move to a third position relative to the tensioner mechanism 114, the rotation of the variable torque rod 108 about the second longitudinal axis of the second shaft 110 corresponding to the rotation about the first longitudinal axis of the first shaft 104 in response to the increase in the angle between the first bracket 102 and the second bracket 106. For example, the second shaft 110 rotates in response to the first bracket 102 and the first shaft 104 rotating to cause the variable torque rod 108 to move in a translational motion in the substantially negative x-direction. When the pair of torque engagement pins 116-1, 116-2 of the tensioner mechanism 114 reach the notch 112-N of the variable torque rod 108, the variable torque rod 108 may translate to a third position, as shown in fig. 1C.

As shown in fig. 1C, the variable torque force may be greater at the third position than at the second position shown in fig. 1B and/or the first position shown in fig. 1A. For example, as shown in fig. 1C, the torque force generated between the variable torque rod 108 and the tensioner mechanism 114 (e.g., when the variable torque rod 108 is in the third position, as shown in fig. 1C) may be greater than the torque force generated between the variable torque rod 108 and the tensioner mechanism 114 (e.g., when the variable torque rod 108 is in the first position, as shown in fig. 1A).

In some examples, this may allow for convenient operation by the user. For example, when first bracket 102 is connected to a display of a computing device, such as a laptop computer, and second bracket 106 can be connected to a housing of the computing device, notch 112-1 corresponds to a first position at an angle of about 0 degrees when the display of the computing device is closed, as shown in fig. 1A. When the variable torque rod 108 is moved to the second position (as shown in fig. 1B) or the third position as described above in connection with fig. 1C, the torque increases. However, the torque force from the first position (shown in fig. 1A) to the second position (shown in fig. 1B) allows the user to easily open the computing device. In some examples, a weaker torque force from the first position to the second position may allow the user to use one hand to open the computing device.

Conversely, since the torque force is greater at the third position than at the first position shown in fig. 1A or the second position shown in fig. 1B, a greater touch force may be used than is used to rotate the first support 102 (shown in fig. 1A) in order to generate an amount of torque for rotating the first support 102 (shown in fig. 1C).

In some examples, the greater torque force shown in fig. 1C may prevent the display of the computing device from rotating when the user touches the display. For example, when a user applies an input by touch, the greater torque force may prevent damage or undesired movement. Rotation by the device 100 against the display may allow the display to be held at a particular angle while providing input to the display via physical touch.

Fig. 2 shows yet another side view of an example of an apparatus according to the present disclosure. The device 200 may include a first bracket 202, a first shaft 204, a second bracket 206, a second shaft 210, a variable torque rod 208, and a tensioner mechanism 214.

As shown in FIG. 2, the device 200 may be oriented in an x-y-z coordinate plane. For example, the x-coordinate as shown in FIG. 2 may be a length, the y-coordinate may be a width, and the z-coordinate may be a height. As shown in the coordinate system shown in fig. 2, the positive x-direction may refer to a direction toward the right side of the page, the positive z-direction may refer to a direction toward the top of the page, and the positive y-direction may refer to a direction away from the page. The negative x-direction may refer to a direction toward the left side of the page, the negative z-direction may refer to a direction toward the bottom of the page, and the negative y-direction may refer to a direction into the page.

As shown in fig. 2, device 200 illustrates a device such as a hinge at a rotational angle. The device 200 may be rotated about the first axis 204 in a clockwise direction as shown in fig. 2 from a first angle of rotation described above in connection with fig. 1A, to a second angle of rotation described above in connection with fig. 1B, to a third angle of rotation described above in connection with fig. 1C.

The device 200 may include a variable torque rod 208 attached to the first bracket 202 via a second shaft 210. The variable torque rod 208 may include a notch 212. Although FIG. 2 is shown with one notch 212, it should be understood that the variable torque rod 208 may have additional notches or utilize a design without notches. For example, the apparatus 200 may include a variable torque rod 208 that utilizes different shapes and diameters and/or contact pressures and/or friction to vary the amount of torque.

In this example, as shown in fig. 2, the tensioner mechanism 214 is a spring that operates by twisting and/or twisting coils about a y-plane of the protrusion 218, which y-plane of the protrusion 218 is substantially the same as the second longitudinal axis of the second shaft 210. The term "protrusion" as used herein may be a bolt, a pin, or any other part of the device and/or an attachment to the device suitable for anchoring a structure or mechanism. Such as tensioner mechanism 214. In the example shown in fig. 2, the coil portion of the tensioner mechanism 214 is shown in a substantially circular arrangement around the protrusion 218. The circular arrangement should not be considered limiting as the coils shown in the diagram 200 may also have a different configuration, such as a spiral shape. In this example, the tensioner mechanism 214 may have a pair of torque engagement pins 216-1, 216-2 that cause twisting/twisting of the coils when the pair of torque engagement pins 216-1, 216-2 are disengaged from each other. In other words, when the pair of torque engagement pins 216-1, 216-2 of the tensioner mechanism 214 are forced away from each other, the coils opposite the pair of torque engagement pins 216-1, 216-2 twist, thereby applying an increasing force in the form of torque to the variable torque rod 208 and the first bracket 202.

The pair of torque engagement pins 216-1, 216-2 may substantially correspond to the notch 212, thereby relieving the pressure/resistance experienced by the tensioner mechanism 214 by allowing the pair of torque engagement pins 216-1, 216-2 to move closer to each other when located at the notch 212. For example, the variable torque rod 208 may move in a substantially negative x-direction in response to a change in the angle between the first bracket 202 and the second bracket 206; when the variable torque rod 208 moves in the negative x-direction, the tensioner mechanism 214 experiences tension in the form of torque around its coil in response to the pair of torque engagement pins 216-1, 216-2 disengaging from one another to accommodate movement of the variable torque rod 208.

FIG. 2 shows a pair of torque engagement pins 216-1, 216-2 that move substantially in the negative z-direction and the positive z-direction. As discussed above in the discussion of fig. 1A, 1B, and 1C, the pair of torque engagement pins 216-1, 216-2 are forced further away from each other in response to movement of the second shaft 210 in the substantially positive z-direction as the angle between the second bracket 206 and the first bracket 202 increases. In other words, as the angle between the second bracket 206 and the first bracket 202 increases, the torque engagement pin 216-1 moves in a substantially negative z-direction, and the torque engagement pin 216-2 moves in a substantially positive z-direction. As the angle becomes larger, the torque force becomes larger. Further, as the angle becomes smaller, the torque force becomes smaller. In some examples, this may allow for easier operation by the user.

Fig. 3 shows a perspective view of an example of a device according to the present disclosure. The apparatus 301 may include a first bracket 302, a first shaft 304, a second bracket 306, a second shaft 310, a variable torque rod 308, and a tensioner mechanism 314.

As shown in FIG. 3, the apparatus 301 may be oriented in an x-y-z coordinate plane. For example, the x-coordinate as shown in FIG. 3 may be a length, the y-coordinate may be a width, and the z-coordinate may be a height. As shown in the coordinate system shown in fig. 3, the positive x-direction may refer to a direction toward the right side of the page, the positive z-direction may refer to a direction toward the top of the page, and the positive y-direction may refer to a direction away from the page. The negative x-direction may refer to a direction toward the left side of the page, the negative z-direction may refer to a direction toward the bottom of the page, and the negative y-direction may refer to a direction into the page.

As shown in fig. 3, device 301 shows the device at a rotational angle. The device 301 may be rotated about the first axis 304 in a clockwise direction as shown in fig. 3 from a first angle of rotation described above in connection with fig. 1A, to a second angle of rotation described above in connection with fig. 1B, to a third angle of rotation described above in connection with fig. 1C.

In the example shown in fig. 3, the perspective view is shown as substantially three-dimensional for clarity. In the example shown in fig. 3, the tensioner mechanism 314 is a spring that operates by twisting and/or twisting coils about the y-plane of the protrusion 318, which is substantially the same as the second longitudinal axis of the second shaft 310.

In the example shown in fig. 3, the tensioner mechanism 314 may have a pair of torque engagement pins 316-1, 316-2 that cause twisting/twisting of the coils when the pair of torque engagement pins 316-1, 316-2 are disengaged from each other. In other words, when the pair of torque engagement pins 316-1, 316-2 of the tensioner mechanism 314 are forced away from each other, the coil opposite the pair of torque engagement pins 316-1, 316-2 experiences tension, thereby applying an increased torque force in the form of a torque to the variable torque rod 308 and the first bracket 302. In other words, as the angle between the second bracket 306 and the first bracket 302 increases, the torque engagement pin 316-1 moves in a substantially negative z-direction, and the torque engagement pin 316-2 moves in a substantially positive z-direction.

Fig. 3 shows a pair of torque engagement pins 316-1, 316-2 that move substantially in the negative z-direction and the positive z-direction. As discussed above in the discussion of fig. 1A, 1B, 1C, and 2, the pair of torque engagement pins 316-1, 316-2 are forced further away from each other in response to the second shaft 310 moving in the substantially positive z-direction as the angle between the second leg 306 and the first leg 302 increases. As the angle becomes larger, the torque force becomes larger. Further, as the angle becomes smaller, the torque force becomes smaller. In some examples, this may allow for easier operation by the user.

For example, when the first stand 302 is connected to a display of a computing device, such as a laptop computer, and the second stand 306 may be connected to a housing of the computing device, the notch 312 corresponds to a first position at an angle of about 0 degrees when the display of the computing device is closed. When the variable torque rod 308 is moved to the second or third position as described above in fig. 1A, 1B, and 1C, the torque increases. However, the torque force from the first position to the second position allows the user to easily open the computing device. In some examples, a weaker torque force from the first position to the second position may allow the user to open the computing device using one hand.

In another example, a large torque force may prevent a display of a computing device from rotating to an undesirable angle when a user touches the display. For example, to prevent damage or unwanted movement when the user applies input through touch. Preventing rotation of the display by the device 301 may allow the display to remain at a particular angle while providing input to the display via physical touch.

Fig. 4 illustrates a side view of an example of a system including a computing device according to the present disclosure. The computing device may include a housing 422 and a rotating element 420.

As shown in fig. 4, the computing device may be oriented in an x-z coordinate plane. For example, the x-coordinate as shown in FIG. 4 may be length, while the z-coordinate may be height. As shown in the coordinate system shown in fig. 4, the positive x-direction may refer to a direction toward the right side of the page, and the positive z-direction may refer to a direction toward the top of the page. The negative x-direction may refer to a direction toward the left side of the page, while the negative z-direction may refer to a direction toward the bottom of the page.

The system 400 may include a computing device. The computing device may be, for example, a laptop computer, among other types of computing devices. The computing device may include a rotating element 420, a housing 422 of the computing device, and may include an apparatus connected to the computing device. The rotational element 420 may be rotated relative to a housing 422 of the computing device via the apparatus. For example, the rotational element 420 may be rotated relative to the housing 422 via the device.

In some examples, the rotating element 420 may be a display. For example, the display may provide information to and/or receive information from a user via a Graphical User Interface (GUI). In some examples, the display may be a touch screen display to provide and/or receive information from a user. The display may be rotated relative to the housing 422 via the device.

FIG. 4 shows a pair of torque engagement pins 416-1, 416-2 that move substantially in the negative z-direction and the positive z-direction. As discussed above in the discussion of fig. 1A, 1B, 1C, 2, and 3, as the angle between the second bracket 406 and the first bracket 402 increases, the pair of torque engagement pins 416-1, 416-2 move and are forced away from each other as the second shaft 410 moves in the substantially positive z-direction. As the angle becomes larger, the torque force becomes larger. Further, as the angle becomes smaller, the torque force becomes smaller. In some examples, this may allow a user to operate more easily than some approaches.

For example, when the computing device of system 400 is a laptop computer, the user may open the laptop computer by grasping display 420 and rotating the display about the first longitudinal axis of 404 while housing 422 remains stationary. The torque force exerted on the bracket 402 is when the angle between the display 420 and the housing 422 is about 0 degrees. In this example, the user is able to open the laptop display with one hand. While this example utilizes a laptop computer, it should be understood that this is not a limiting example and that other types of computing devices may be utilized.

Conversely, other methods may utilize another hand or device to hold the housing 422 stationary so that the display may be rotated about the first longitudinal axis of the first shaft 404.

In another example, when the housing 422 of the computing device remains stationary, the display 420 may rotate about the first longitudinal axis of the first shaft 404, with the torque increasing. When the torque increases as described in fig. 1A, 1B, 1C, 2, and 3, the display 420 may be rotated with more touch force from the user. In some examples, this may prevent undesired movement or damage to the computing device.

For example, some computing devices accept input from a user through physical touch. The increased torque as described above may prevent undesired movement of the display 420 or damage to the computing device, which may be caused by inadvertently increasing the angle between the first bracket 402 and the second bracket 406.

Although not shown in fig. 4 for clarity and so as not to obscure examples of the present disclosure, the computing device may include a second apparatus as described in the present disclosure. The second apparatus may be located on an opposite side of the computing device. For example, the second apparatus may be oriented in a similar manner as the apparatus shown in fig. 4 and located on the opposite side of the computing device apparatus shown in fig. 4.
