Background

Some display devices may include mechanical structures that enable the display to rotate. For example, the rotating display device may be mounted on a wall, a table, or a floor stand via a mounting assembly that enables a user to rotate the display device. In this manner, a user may view and interact with content on the rotating display device in any of a plurality of display orientations. In some examples (such as a display that cannot rotate displayed content to match device rotation), enabling device rotation may provide a negative user experience.

SUMMARY

This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter. Furthermore, the claimed subject matter is not limited to implementations that solve any or all disadvantages noted in any part of this disclosure.

Disclosed examples relate to a locking mechanism, a display assembly, and a method for modifying a mounting assembly of a display assembly to enable rotation of a display. In one example, the locking mechanism includes a lock block mounted for rotation with the display. The locking mechanism also includes a lever rotatably coupled to the plate of the mounting assembly. The lever includes a locking tab that blocks movement of the lock block when the lever is in the locked position and allows movement of the lock block when the lever is in the unlocked position.

Another example provides a display assembly comprising: a mounting assembly, a display rotatably coupled to the mounting assembly, a removable cartridge (cartridge) including at least one protrusion, and a locking mechanism. The locking mechanism includes a lock block mounted for rotation with the display. The locking mechanism also includes a lever rotatably coupled to the plate of the mounting assembly. The lever includes a locking tab that blocks movement of the lock block when the lever is in the locked position and allows movement of the lock block when the lever is in the unlocked position. The lever also includes a latch bolt. The protrusion of the removable cartridge is configured to (1) engage the latch bolt to move the lever into the locked position or (2) engage the latch bolt to move the lever into the unlocked position.

Another example provides a method for modifying a mounting assembly of a display assembly to allow rotation of a display. The method includes removing the removable cartridge from the mounting assembly to disengage the locking tab of the removable cartridge from the latch bolt of the locking mechanism. When the locking tab is disengaged from the latch bolt, the lever of the locking mechanism moves from the locked position to the unlocked position. The lever includes a locking tab that blocks movement of a locking block fixedly coupled to the display when the lever is in a locked position. When the lever of the locking mechanism is moved to the unlocked position, the locking tab is moved out of the way of the locking block and rotation of the display is permitted.

Detailed Description

Some display devices may include mechanical structures that enable the display to rotate. Some examples of rotatable display devices include all-in-one computing devices, electronic whiteboards, and other interactive collaboration devices. Such devices may be mounted on a wall, a floor stand, a rolling cart, or any other suitable surface or object via a mounting assembly that enables a user to rotate the display. In this manner, a user may view and interact with content on the rotating display device in any of a plurality of display orientations, such as portrait orientation and landscape orientation.

In some examples (such as a display that cannot rotate displayed content to match device rotation), enabling device rotation may provide a negative user experience. For example, if the user rotates the display device 90 degrees from landscape orientation to portrait orientation, the displayed content may also be rotated 90 degrees to one side thereof along with the display. This may make the content difficult to view or understand.

For example, a user may purchase a display device having a rotatable display. The display device may be initially shipped with the computing system unable to rotate the displayed content. In some examples, the computing system may be later updated or upgraded to enable rotation of the displayed content. In these examples, it may be desirable to selectively disable and enable rotation of the display to match the capabilities of the computing system. One method of disabling/enabling rotation may include using one or more removable fasteners, such as screws or bolts, to secure the display in place. However, such fasteners may be difficult to obtain and may be difficult to selectively secure and release if a user desires to enable/disable rotation of the device.

Accordingly, disclosed examples relate to a locking mechanism for a display assembly that selectively allows rotation of a display. As described in more detail below, the removable cartridge may include one or more protrusions that engage the locking mechanism to enable/disable rotation of the device. The locking mechanism includes a lock block mounted for rotation with the display and a lever including a lock plate that blocks movement of the lock block (and thus the display) when the lever is in a locked position. The locking tab allows movement of the locking piece when the lever is moved to the unlocked position. Additionally, the lever may be configured such that a protrusion on the removable cartridge may (1) engage the latch bolt to move the lever into the locked position, or (2) engage the latch bolt to move the lever into the unlocked position. In this manner, the locking mechanism may selectively enable or prevent rotation of the display.

Referring now to fig. 1A and 1B, one example of a display assembly 100 is provided in the form of an electronic whiteboard. The example of the display assembly 100 is provided for illustrative purposes and is not intended to be limiting. Other examples to which the present disclosure may be applied (such as televisions, computer monitors, and all-in-one computing devices) may have different shapes, different sizes, and different numbers and/or arrangements of features than the display assembly 100 shown in fig. 1A and 1B.

The display assembly 100 includes a display 104 rotatably coupled to a mounting assembly 108. The display may use any suitable display technology, such as LED, OLED, LCD, LCoS, and the like. The mounting assembly 108 may be coupled to a wall, a mounting bracket, a rolling cart, or another suitable anchoring surface. The mounting assembly 108 may include one or more structures configured to enable rotation of the display. For example, fig. 2 illustrates a portion of the mounting assembly 108 that includes a rail plate 204 coupled to the display 104. The rail plate 204 is rotatably coupled to a roller plate (roller plate)208, and the roller plate 208 may be secured to a housing of the mounting assembly 108 that is coupled to a wall, mounting bracket, rolling cart, or other anchoring surface. In this example and referring also to fig. 1A and 1B, the rail plate 204 and the roller plate 208 are substantially parallel to the X-Y plane in which the display 104 rotates.

The rail plate 204 and the roller plate 208 may be coupled via any suitable means that enables the rail plate 204 to rotate relative to the roller plate 208. For example, the rail plate 204 and the roller plate 208 may be coupled via bearings, wheels, interlocking rails and tracks, or a gear system. In this manner, the display 104 and any other components of the display assembly 100 attached to the rail plate 204 may rotate relative to the roller plate 208 and the anchoring surface to which the roller plate is mounted. For example, and referring again to fig. 1A, in some examples, the display 104 may be rotated 90 degrees about the mounting assembly 108. In this manner, the display 104 may be rotated between a landscape orientation 110 and a portrait orientation 112.

The display assembly 100 includes a removable cartridge 116, the removable cartridge 116 being removably inserted into the mounting assembly 108. The removable cartridge 116 may include a computing device that generates image content for the display 104. In the example depicted in fig. 1A and 1B, the removable cartridge 116 is inserted into the mounting assembly 108 behind the display 104 and removed from the mounting assembly 108 behind the display 104. In this example, the removable cartridge 116 resides in a portion of the mounting assembly that does not rotate with the display.

While the removable cartridge 116 moves in the Y-axis direction during insertion and removal in the example depicted in fig. 1, it will also be appreciated that the removable cartridge may be inserted and removed in the X-axis or other direction based on the orientation of the mounting assembly 108.

As described above, it may be desirable to selectively enable rotation of the display 104. Accordingly, as illustrated by example in fig. 2, the mounting assembly 108 may include a locking mechanism 216, which locking mechanism 216 may selectively allow display rotation when the mechanism is unlocked and disable display rotation when the mechanism is locked.

The locking mechanism 216 includes a locking lever 220, the locking lever 220 being rotatably coupled to the roller plate 208 of the display assembly via a pivot 224. The pivot 224 may include a bolt, screw, bearing, or any suitable component about which the locking lever 220 may rotate. In this manner and as described in more detail below, the locking lever 220 may be moved between the locked and unlocked positions by rotating about the pivot 224.

In the example of fig. 2, the locking lever 220 is illustrated in a locked position 228. When the locking lever 220 is in the locked position 228, a locking tab 240 of the lever (see fig. 3) may engage one or more components coupled to the track plate 204 to prevent the display from rotating. More specifically and as illustrated in the examples in fig. 2 and 3, the locking mechanism 216 includes a lock block 236. The lock block 236 is fixedly coupled to the rail plate 204 such that the lock block 236 rotates with the rail plate 204 and the display. The lock block 236 may be mounted to the bottom side of the rail plate 204. In the example of fig. 2 and 3, the lock block 236 is oriented parallel to the X-Y plane and coplanar with the locking bar 220.

When the locking lever 220 is in the locked position 228 (shown in fig. 2 and 3), the locking lever 220 engages the lock block 236 to prevent rotation of the display. More specifically and as illustrated in fig. 3A, the locking lever 220 is engaged with the lock block 236 via an upwardly extending lock tab 240. In the example of fig. 3A, locking tab 240 includes a portion of locking lever 220 that extends away from the locking lever in the positive Y-axis direction toward lock block 236. As shown in fig. 3A, when the locking lever 220 is in the locked position 228 and the display 104, track plate 204, and lock block 236 are oriented as shown, the lock tab 240 extends in front of the lock block 236. In this manner, the locking tab 240 blocks the lock block 236 (and the display 104 and track plate 204) from moving/rotating in the clockwise direction 120. More specifically, if the user attempts to rotate the display in the clockwise direction 120, the blocking face 226 of the lock block 236 contacts the lock plate 240 to prevent the lock block 236 from moving past the lock plate.

In one example, and referring again to fig. 1, when the display 104 is oriented in the landscape orientation 110, the locking lever 220 is in the locked position 228 shown in fig. 3A. Accordingly, rotation of the display 104 in the clockwise direction 120 is prevented and the display is locked in the landscape orientation.

In the example of fig. 3A, the locking tab 240 extends in front of the lock block 236 to block the travel path of the lock block and correspondingly block rotation of the display. In other examples, the locking tab 240 may engage with the locking block 236 in any other suitable manner, such as by being inserted into an aperture of the locking block. In some examples and as described in more detail below, the display assembly 100 may also constrain rotation in an opposite, counterclockwise direction.

Referring now to fig. 4, and as described in more detail below, when a user removes the removable cartridge 252 of fig. 3A and/or inserts a different removable cartridge 254, the locking mechanism 216 can be pivoted to the unlocked position 248, as shown in fig. 4. In the example of fig. 4, the locking lever 220 is in an unlocked position 248, where the locking tab 240 does not block movement of the locking tab 236 or any other component coupled to the rail plate 204 in the unlocked position 248. Accordingly, when the locking lever 220 is in the unlocked position 248, the display may be rotated. In this example, the locking lever is biased toward the unlocked position 248 via a spring 262. In other examples and as described below, other biasing elements may be used to bias the locking bar toward the locked position, the unlocked position, or the centered position.

In some examples, the locking mechanism may be selectively engaged or disengaged by interacting with one or more components of the removable cartridge. For example, and referring to fig. 2, 3, and 5A, in this example, removable cartridge 252 includes a protrusion 256 extending outward from the cartridge in the positive Z-axis direction. When the removable cartridge 252 is installed in the mounting assembly 108 in the positive Y-axis direction (as shown in fig. 2 and 3), the protrusion 256 engages a latch bolt 260 on the distal end of the locking lever 220 (see also fig. 7). The protrusion 256 pushes the latch bolt 260 in the positive Y-direction as the removable cartridge 252 is installed, thereby moving the locking lever 220 into the locking position 228 and locking the display assembly from rotation. In this manner, rotation of the display may be conveniently and selectively disabled by simply installing the cartridge 252 into the display assembly.

As described above, in this example, the locking lever is biased toward the unlocked position 248 via the spring 262. Accordingly, and with reference to fig. 4 and 5B, when the removable cartridge 254, which does not include the protrusion 256, is inserted into the mounting assembly, the locking lever 220 remains in the unlocked position 248 and the display 100 remains free to rotate in the clockwise direction 120.

In one example, the user may remove the cartridge 252 with the tab 256 and then rotate the display (and lock block 236) clockwise away from 0 degrees (landscape orientation). It is possible that the user may then reinsert the same cartridge 252 with the tab 256. This will rotate lever 220 to the locked position 228, but lock block 236 has been rotated away and is not in place. Further, rotating the display 104 and lock block 236 back to a landscape orientation with the locking lever 220 in the locked position 228, or otherwise forcing the lock into engagement may damage one or more components of the locking mechanism.

Accordingly and in some examples, the rod 220 and lock block 236 may be configured to allow the lock block to pass over the rod and properly engage once at 0 degrees. More specifically, and referring now to fig. 6 and 7, in some examples, the lock block 236 may include at least one ramped surface 250, the at least one ramped surface 250 enabling the lock block to slide along a corresponding ramped surface 276 of the locking lever 220 from which the latch bolt 260 extends. Fig. 6 and 7 show the locking bar 220 and lock block 236 in a view flipped 180 degrees about the y-axis relative to the views shown in fig. 2-4 to show additional detail of the locking bar and lock block.

As shown in fig. 6 and 7, the lock block 236 includes a ramped surface 250 at a distal end opposite the stop face 226. The inclined surface 250 may include a flat surface or a curved surface that is inclined from a leading edge (leading edge) of the lock piece to a flat surface. As illustrated by example in fig. 6, the ramped surface 250 of the lock block 236 may be configured to contact the corresponding ramped surface 276 of the locking lever 220 when the locking lever is in the locked position. The ramped surface 250 may be configured such that the lock block 236 may wedge itself under the locking bar 220, as shown in fig. 6. In this manner, the lock block 236 may pass under the locking lever 220 when moved in the direction indicated by arrow 628, which may prevent jamming and enable the display to rotate into the locked orientation.

In some examples, the lock block 236 may move the rail plate 204 and roller plate 208 slightly apart as it slides under the locking lever 220, as illustrated in fig. 7, before the display assembly returns to its normal state once it is engaged with the locking lever. In this manner, the ramped surfaces 250 and 276 may enable the lock block 236 to slide under the locking bar 220 to the position shown in fig. 7 without damaging itself, the locking bar 220, and/or other components.

As described above, the interaction of the lock block and the locking bar may constrain the rotation of the display in one direction. In some examples, it may also be desirable to restrict rotation of the display in the opposite direction. In the example of fig. 3A-3C, the display assembly includes a buffer 264. The buffer 264 may be housed in a storage area 268 that at least partially surrounds the buffer 264. The storage area 268 may be secured to the track plate 204 such that the storage area and the bumper 264 rotate with the display.

The display assembly 100 may also include a stop 272, the stop 272 being fixed to the roller plate 208 and configured to slide into the storage area 268 via an aperture 282 on the right end of the storage area. More specifically, when the display 104 and track plate 204 reach the end of their range of rotation in a counterclockwise direction, the aperture and storage area receive the stop 272 (i.e., the stop is inserted into the garage 268) until the left end of the stop contacts the bumper 264. The range of rotation may be set by the equipment manufacturer by adjusting the position of the storage area 268 and/or the stop 272. For example, the display may reach the end of the range of rotation when the lock block 236 is engaged with the lock plate 240.

Bumper 264 may comprise a compressible material, such as rubber, or may take the form of a spring. In this manner, the bumper 264 may be compressed by the stop 272. When the bumper 264 is compressed, the bumper may exert a restoring force that pushes against the stop 272. For example, when the stopper 272 compresses the bumper 264 in the negative X-axis direction, the bumper 264 may generate a restoring force acting against the stopper in the positive X-axis direction. It will be appreciated that in some examples, the display assembly may include a plurality of bumpers and stops that may provide a more uniform application of force around the assembly.

In the locked position, a preload between lock block 236 and lock plate 240 may be desired. Such preloading may prevent the display from feeling loose or wobbling in the rotational direction. In some examples, lock block 236 may be biased toward lock plate 240 when the display assembly is manufactured. Providing such a biasing force compresses bumper 264 and preloads lock block 236 against lock plate 240.

The restoring force provided by bumper 264 ensures that lock block 236 remains in contact with lock plate 240 with locking mechanism 216 engaged. In some examples, such a force may prevent locking tab 240 and locking piece 236 from disengaging immediately when removable cartridge 252 is removed, as in the example where the locking bar is biased toward the unlocked position. In these examples, locking bar 220 may be free to pivot by disengaging locking tab 240 and locking tab 236 after removal or replacement of removable cassette 252 by further compressing bumper 264 (such as by slightly rotating or biasing the display in a counterclockwise direction). In other examples and as described below, the removable cartridge may include an unlocking protrusion that engages the locking lever 220 upon insertion to move the lever to the unlocked position.

In various configurations, the locking lever 220 may be biased toward the unlocked position by at least one biaser. The biaser may include any suitable component(s), such as a spring, magnet, or cam and follower, that biases the locking bar 220 toward the unlocked position 248. In the example shown in fig. 2-4, the locking lever 220 is biased toward the unlocked position 248 via a spring 262. In other examples, as described in more detail below, the biaser 262 may be configured to bias the locking lever 220 toward the locked position 228 or toward a centered position between the locked position 228 and the unlocked position 248.

In another example and referring to fig. 3D, one or more magnets may be used to provide a biasing force to the locking bar. In the example of fig. 3D, the locking lever 304 rotatably coupled to the roller plate 308 includes a first magnet sequence 310 on a first arm 312 and a second magnet sequence 316 on an opposing second arm 320. The track plate 308 beneath the lock bar 304 includes corresponding first and second magnet sequences 330 and 334. In one example, the lock bar magnets 310, 316 have an opposite polarity to the track plate magnets 330, 334 to thereby attract the track plate magnets and bias the lock bars into the unlocked position. In another example, the lock bar magnets 310, 316 have the same polarity as the track plate magnets 330, 334 to thereby repel the track plate magnets and bias the lock bars into the locked position.

In yet another example and referring to fig. 3E, a cam and follower system may be used to provide a biasing force to the locking bar. In the example of fig. 3E, the locking bar 336 includes a slot 340. Follower arrangement 344 is positioned within slot 340. The follower 344 may be mounted on one or more of the guide 348 or a groove within the slot 340 to travel along the x-axis. The follower 344 may be loaded by a spring 352 such that a contact surface 356 of the follower 344 is biased against the cam 360. In this manner, the follower 344 may push against the cam 360 with a force that biases the locking bar 336 in the locked or unlocked position.

In some examples and referring again to fig. 4, by biasing the locking lever 220 toward the unlocked position 248, the display 104 may be enabled to rotate by default. For example, when the removable cartridge 252 is removed/uninstalled, or when a removable cartridge 254 that does not include the tab 256 is used (as shown), the display may be unlocked for rotation.

In other examples, the locking bar may be biased toward the locked position. Fig. 8 shows another example of a portion of a mounting assembly 800. The mounting assembly 800 includes a locking mechanism 804 having substantially the same configuration as the locking mechanism 216 described above. The locking mechanism 804 includes a locking bar 808 having substantially the same configuration as the locking bar 220. Similar to the locking lever 220 in the example of fig. 2-4, the locking lever 808 is rotatably coupled to the roller plate 812 of the mounting assembly 800. In this example, the locking mechanism 804 includes a locking spring 816 configured to bias the locking bar 808 toward the locked position 820. Accordingly, in such a configuration, the mounting assembly 800 may remain locked by default. For example, when the removable cartridge 252 is removed, or when a different removable cartridge without the protrusion 256 is installed, the display 104 will be locked from rotation.

In some configurations in which the locking lever is biased toward the locked position, the locking lever may be disengaged and the display may be rotated by installing a removable cartridge having an unlocking tab that engages the locking lever and moves the locking lever to the unlocked position. For example, fig. 9 shows another example of a portion of a mounting assembly 828 having a locking mechanism 930, the locking mechanism 930 including a locking lever 832 that is normally biased toward a locked position in which a locking tab 852 moves upward behind a track plate 854 to abut a locking tab (not shown). In the example of fig. 9, the locking mechanism may be unlocked by engaging the first latch bolt 836 of the locking lever 832 with an unlocking tab on the removable cartridge to move the lever to the illustrated unlocked position 840.

For example and referring also to fig. 11B, the removable cartridge 258 may include an unlocking protrusion 844, the unlocking protrusion 844 configured to engage and move the first latch bolt 836 when the cartridge is installed. When the removable cartridge 258 is installed, as shown in the example of fig. 9, the unlocking tab 844 can be engaged with the latch bolt 836 to urge the latch bolt 836 in the positive Y-axis direction, causing the lever 832 to rotate about the pivot 848 and the locking tab 852 to translate in the negative Y-direction toward the unlocked position 840. In this manner, display assembly 828 may be unlocked, allowing the display to rotate.

In some examples in which the locking lever is biased towards the locked position, a removable cartridge including one or more locking tabs may be used to ensure that the display assembly remains locked from rotation when the cartridge is installed.

In other examples and as described in more detail below, locking lever 832 may be biased toward a centered position in which the locking lever is neither fully engaged in the locked position nor fully engaged in the unlocked position. In these examples, and in examples in which the locking lever has been biased toward the unlocked position, one or more unlocking tabs may be provided on the removable cartridge to ensure that the display assembly remains unlocked.

As described above, the display 104 may be locked in various desired orientations in different configurations. For example, the display assembly 828 shown in fig. 9 may additionally or alternatively be configured such that the locking lever 832 locks the display when the display is in the portrait orientation. In some examples, one or more lock blocks may be positioned at different locations around the display assembly.

For example, fig. 10 shows another example of a mounting assembly 956. Mounting assembly 956 may include a locking mechanism 960, which may include locking mechanism 930 described above with reference to fig. 9. Mounting assembly 956 may also include longitudinal locks 964 secured to rail plates 966 in an area offset approximately 90 degrees from lateral locks 968. In this manner, the locking mechanism 960 may engage the longitudinal lock block 964 to lock the display when the display is rotated clockwise 90 degrees from a landscape orientation to a portrait orientation.

In the example of fig. 10, the locking lever 832 is illustrated in a laterally unlocked/longitudinally locked position with the left locking tab 852 pivoted downward and the right locking tab 858 (see fig. 9) pivoted upward in the opposite direction to engage the longitudinal locking tab 964. Accordingly, in this configuration, the locking mechanism 960 engages the longitudinal lock block 964 to lock the display in a longitudinal orientation.

In some examples, mounting assembly 956 also receives a removable cartridge as described above. The removable cartridge may include at least one protrusion to lock or unlock the locking mechanism 960. For example, the removable cartridge 258 described above with reference to fig. 9 includes a tab 844, which tab 844 can be configured to engage the locking mechanism 960 to lock the display in a longitudinal orientation by engaging with the latch bolt 836 to move the locking plate 858 upward to engage with the longitudinal locking piece 964.

In other examples, the removable cartridge and corresponding protrusion may be configured in any suitable manner to lock the display in a portrait orientation or a landscape orientation. For example, and referring also to fig. 5A, removable cartridge 252 may be used with mounting assembly 956 such that tab 256 engages with latch bolt 862 on locking lever 832 to pivot locking tab 852 upward and lock the display in a landscape orientation. Additionally and in different examples, mounting assembly 956 may be oriented and secured to an anchoring surface such that removable cartridge 252 is inserted and removed vertically in the y-axis direction or horizontally in the x-axis direction.

It will also be appreciated that various other combinations of configurations of display assemblies, locking mechanisms, and protrusions on the removable cartridge may be used to selectively allow rotation of the display, as well as to selectively lock and unlock rotation. For example, and as described above, the cartridge 258 shown in fig. 11A includes a tab 844 that can engage the lateral locking mechanism and unlock the display from a lateral orientation.

In some examples and referring to fig. 11B, removable cartridge 284 may include one or more apertures configured to removably receive protrusions at different locations on the cartridge. In this manner, a user may configure removable cartridge 284 to have tabs in different positions to lock or unlock the display in any suitable orientation (e.g., portrait or landscape). For example, removable cartridge 284 may include an aperture 870, which aperture 870 is configured to receive protrusion 844 (see also fig. 11A). Removable cartridge 284 may optionally include one or more additional apertures (such as apertures 860, 864, and 872) that may receive protrusions configured to interact with locking mechanisms having different locking functionalities. In different examples, the tab may be removable by the user or by an authorized support technician.

For example, the user may install a tab in aperture 860 that is located in the same position as tab 256 in removable cartridge 252 depicted in fig. 5A. In this manner, removable cartridge 284 may be configured to lock display assembly 956 of fig. 10 in either a portrait orientation or a landscape orientation.
