Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

Referring to fig. 1 to 4, fig. 1 is a perspective view of a portable bed curtain frame 100 provided in an embodiment of the present application in a first state; fig. 2 is a front view of a portable bed curtain frame 100 in a first state according to an embodiment of the present application; fig. 3 is a left side view of a portable bed curtain frame 100 in a first state according to an embodiment of the present application; fig. 4 is a top view of a portable bed curtain frame 100 in a first state according to an embodiment of the present application. The first state here represents a state in which the portable bed curtain frame 100 is in an extended state, i.e., a state in which it is not retracted or folded.

In this embodiment, the portable bed curtain frame 100 may include a transverse beam 110, a longitudinal support frame 120, and a fixing hook 130, wherein the transverse beam 110 is used for supporting the outline of the bed curtain, the longitudinal support frame 120 is used for supporting the transverse beam 110, and the fixing hook 130 is used for hooking the bed frame.

Illustratively, the limited rotational connection between the transverse beam 110 and the longitudinal support frame 120 means that the transverse beam 110 and the longitudinal support frame 120 are mutually abutted or mutually folded through the relative rotation between the transverse beam 110 and the longitudinal support frame 120.

Illustratively, the fixing hooks 130 (for hooking the frame) are connected to the longitudinal support frame 120 to keep the portable curtain frame 100 fixed to the frame, wherein the fixing hooks 130 and the transverse beam 110 are respectively located at both ends of the longitudinal support frame 120.

Illustratively, the transverse beam 110 may be a closed frame to support the outline of the curtain. For example, the frame may be a frame similar to a rectangle, a frame similar to an ellipse, a frame similar to a shape formed by splicing a semicircle and a rectangle, and the like, and the frame is not limited herein. The rectangular transverse beam frame 110 is described as an example in the present embodiment, but should not be construed as limiting the present application.

In this embodiment, when the transverse beam frame 110 and the longitudinal support frame 120 abut against each other, a first included angle between the transverse beam frame 110 and the longitudinal support frame 120 may be within 90 ° to 120 ° (for example, when the transverse beam frame 110 and the longitudinal support frame 120 are perpendicular, the first included angle is 90 °, when the transverse beam frame 110 needs to tilt up slightly, the first included angle may be 100 °, 110 °, 120 °, and the like, which is not limited herein), after the transverse beam frame 110 and the longitudinal support frame 120 are folded, the transverse beam frame 110 is stacked on one side of the longitudinal support frame 120, and a second included angle between the fixing hook 130 and the longitudinal support frame 120 is within 75 ° to 90 ° (for example, the fixing hook 130 may be perpendicular to the longitudinal support frame 120, and at this time, the second included angle is 90 °, the longitudinal support frame 120 may be considered perpendicular to the ground, and if the longitudinal support frame 120 needs to have some inclination, the second included angle may be 80, 75 deg., etc., so that the pattern of transverse beam mounts 110, longitudinal support brackets 120, and attachment hooks 130 somewhat resembles a "Z" pattern, such as that shown in fig. 2).

The portable bed curtain frame 100 comprises a transverse beam frame 110 (for supporting the outline of the bed curtain), a longitudinal support frame 120 (for supporting the transverse beam frame 110) and a fixing hook 130, wherein the transverse beam frame 110 is connected with the longitudinal support frame 120 in a rotation limiting manner (the transverse beam frame 110 and the longitudinal support frame 120 are connected with each other in an abutting or folding manner) through relative rotation. The fixing hooks 130 (for hooking the bed frame) are connected to the longitudinal support frame 120, and the fixing hooks 130 and the transverse beam frame 110 are respectively located at two ends of the longitudinal support frame 120, so that the portable curtain frame 100 and the bed frame are fixed. The bed curtain frame is simple in structure and convenient to use, can be made of metal materials or other materials with hard texture, is very light and small, and can well guarantee quality. When the bed curtain frame is not used, the transverse beam frame 110 and the longitudinal support frame 120 can be mutually folded, so that the portable bed curtain frame 100 can be folded, and the portable bed curtain frame is small in size and small in occupied space. When the transverse beam frame 110 and the longitudinal support frame 120 are abutted against each other, a first included angle between the transverse beam frame 110 and the longitudinal support frame 120 is within 90-120 degrees, after the transverse beam frame 110 and the longitudinal support frame 120 are folded with each other, the transverse beam frame 110 is stacked on one side of the longitudinal support frame 120, and a second included angle between the fixing hook 130 and the longitudinal support frame 120 is within 75-90 degrees. This allows the curtain to be hung on the transverse beam 110, and the fixing hooks 130 to be fixed to the frame, thereby ensuring the stability of the installation of the portable curtain frame 100 on the frame. In addition, a first included angle between the transverse beam frame 110 and the longitudinal support frame 120 is within 90-120 degrees, and a second included angle between the fixing hook 130 and the longitudinal support frame 120 is within 75-90 degrees, so that the gravity center of the bed curtain frame is more deviated to the position of the longitudinal support frame 120, and the stability and the reliability of the portable bed curtain frame 100 are further improved. During the process of installing the curtain frame, the curtains can be installed together, for example, the curtains can be installed on the transverse beam frame 110 before the transverse beam frame 110 is extended, so that the curtains can be driven to move together when the transverse beam frame 110 is extended, and the installation of the curtains can be completed very conveniently and quickly.

In this embodiment, the transverse beam 110 may have opposite telescopic and folding ends 111 and 112, the telescopic end 111 being partially or wholly embedded within the folding end 112 when the telescopic end 111 is moved towards the folding end 112 to effect contraction of the transverse beam 110; and as the telescopic end 111 moves away from the folding end 112, the portion of the telescopic end 111 which is embedded within the folding end 112 is reduced to effect extension of the transverse beam 110. Correspondingly, the folded end 112 is in limited rotational connection with the longitudinal support 120.

The transverse beam 110 has opposite telescopic and folding ends 111 and 112 so that the telescopic end 111 can be partially or fully embedded in the folding end 112 to effect contraction and extension of the transverse beam 110. On one hand, the portable bed curtain frame 100 can be lightened, and the convenience of using the portable bed curtain frame 100 is ensured; on the other hand, the mode can also reduce the damage and the wear of the transverse beam frame 110 in the using process, and is beneficial to prolonging the service life of the portable bed curtain frame 100. Moreover, when the bed curtain is installed, the bed curtain can be driven to run through the running of the telescopic end 111, so that the bed curtain is more convenient to install.

In this embodiment, the longitudinal supporting frame 120 may include a plurality of supporting rods, each supporting rod has a first end 1211 and a second end 1212 opposite to each other, a folding element 1213 is disposed on each supporting rod between the first end 1211 and the second end 1212 for folding the supporting rod, and when the supporting rod is folded, a portion of the first end 1211 and a portion of the second end 1212 are overlapped with each other to fold the longitudinal supporting frame 120. Correspondingly, each support rod is connected with the folding end 112 in a limited rotation manner, and each support rod is connected with a fixing hook 130.

The longitudinal support frame 120 comprises a plurality of support rods, each support rod has a first end 1211 and a second end 1212 opposite to each other, each support rod is provided with a folding element 1213 for folding the support rod, when the support rod is folded, the portion of the first end 1211 and the portion of the second end 1212 are overlapped with each other to fold the longitudinal support frame 120. Thus, the portable bed curtain frame 100 can be further miniaturized by the folding mode, and the folding mode can more reliably ensure the reliability of the folding portable bed curtain frame 100 when in use compared with the simple telescopic mode due to the existence of the gravity factor.

Illustratively, the longitudinal support frame 120 may include two support rods: a first support bar 121 and a second support bar 122, the first support bar 121 and the second support bar 122 being connected by a connecting bar 140.

The first support rod 121 and the second support rod 122 of the longitudinal support frame 120 are connected through the connecting rod 140, and the relative distance between the first support rod 121 and the second support rod 122 can be limited, so that the consistency of the longitudinal support frame 120 on the width is ensured, the width deformation is avoided, and the quality of the portable bed curtain frame 100 is ensured.

Of course, this is only exemplary, and in other possible implementations, the longitudinal support frame 120 may include more than two support rods, for example, 4 support rods, which may be disposed equidistantly to ensure the support effect of the longitudinal support frame 120. In other possible implementations, the longitudinal support 120 may further include a support rod, and two joints may be respectively disposed at two ends of the rod body and are respectively connected with two end points of the folding end 112 in a limited rotation manner, which is not limited herein.

In this embodiment, one end of each fixing hook 130 away from the supporting rod connected thereto is provided with a folding hook 131, and the folding hook 131 faces the direction of the other fixing hook 130. The stable connection between the fixing hook 130 and the bed frame can be realized by the folding hook 131 arranged on the fixing hook 130, and the folding hook 131 arranged on the fixing hook 130 can also be used for keeping a constant position with the bed frame, so that the positions of two end points of the folding end 112 keep a constant position in the length direction, thereby preventing the portable bed curtain frame 100 from generating a staggered deformation problem (i.e. staggered in the length direction of the transverse beam frame 110). Therefore, such a manner may further ensure the quality and reliability of use of the portable bed curtain frame 100.

In addition, the size of each fixing hook 130 may be designed based on the height of the entire portable curtain frame 100 and the length of the transverse beam 110 as a reference to ensure that the fixing hook 130 can stably hook the bed frame, thereby realizing the fixing of the portable curtain frame 100. For example, the transverse beam 110 of the portable curtain 100 is 1.8 meters, and the height of the longitudinal support frame 120 is 1.5 meters, then the dimension (length, width, height) of the fixing hooks 130 may be between 100mm, 50mm, 5mm, and 30mm, 100mm, and 10mm, which is not limited herein.

In order to further ensure the quality of the fixing hook 130 and the fixing effect on the portable bed curtain frame 100, a transverse plate connected with the fixing hook 130 may be further disposed below the fixing hook 130, and the transverse plate may be perpendicular to the longitudinal support frame 120, so that when the portable bed curtain frame 100 is mounted on a bed frame, the transverse plate may be pressed under the bed, thereby further ensuring the fixing effect of the fixing hook 130 on the portable bed curtain frame 100. Of course, this is merely an example illustration and should not be construed as a limitation of the present application.

Illustratively, for each such support rod, the rod is connected in limited rotational movement to the folded end 112 by a shear pin 150.

Referring to fig. 5, fig. 5 is a schematic structural diagram of a safety pin 150 according to an embodiment of the present disclosure. The safety pin 150 may include a sliding rod 151 disposed at an end position of the first end 1211 on the supporting rod and a sliding rail member 152 disposed at an end position of the folded end 112.

Illustratively, the slide rail member 152 is provided with an arc guide rail 1521, the arc tail end of the arc guide rail 1521 is connected with a reverse clamping guide rail 1522, the reverse clamping guide rail 1522 extends in a direction opposite to the arc tail end, and the reverse extension here indicates that an angle between a straight line in which the extension direction of the reverse clamping guide rail 1522 is located and a tangent line in the extension direction of the arc tail end is not less than 90 °.

Illustratively, the end positions of the sliding rod 151 and the first end 1211 are kept fixed, and the sliding rod 151 extends into the sliding rail member 152 to slide along a circular arc track in the circular arc guide rail 1521, or slide into the reverse retaining guide rail 1522 and abut against the end of the reverse retaining guide rail 1522.

In this way, the relative rotation between the transverse beam 110 and the longitudinal support frame 120 can be realized, and after the sliding rod 151 enters the reverse clamping guide 1522, the transverse beam 110 makes the sliding rod 151 and the reverse clamping guide 1522 abut against each other under the action of the gravity of the transverse beam 110, so that the relative fixation between the transverse beam 110 and the longitudinal support frame 120 is realized. When the transverse beam frame 110 and the longitudinal support frame 120 need to be switched from the mutual abutting state (i.e. the portable curtain frame 100 is in the extending state) to the mutual folding state, the transverse beam frame 110 can be lifted and moved for a short distance, so that the sliding rod 151 enters the circular arc guide rail 1521, and the mutual folding between the transverse beam frame 110 and the longitudinal support frame 120 can be completed. Therefore, the abutting mode and the fixing mode are very convenient and reliable, the connecting structure is simple, and the operation is convenient and fast.

Of course, in this embodiment, the guide rail formed on the slide rail component 152 may not be the circular arc guide rail 1521, but may be a combination of a folded guide rail and a reverse clamping guide rail 1522, so that when the transverse beam frame 110 and the longitudinal support frame 120 are mutually abutted, no external force is applied, the slide rod 151 runs along the sliding track of the folded guide rail and the reverse clamping guide rail 1522, and the abutting state between the transverse beam frame 110 and the longitudinal support frame 120 is not changed, so that the portable bed curtain frame can maintain good stability, the safety of using the portable bed curtain frame can be improved, and people cannot fall down and hit the portable bed curtain frame.

In this embodiment, when the transverse beam frame 110 and the longitudinal support frame 120 abut against each other, the transverse beam frame 110 is arched upwards by a predetermined arc. Thus, the convenience of the bed curtain in use can be ensured, and the transverse beam frame 110 arched upwards by a preset radian can overcome the shrinkage problem of the bed curtain, so that the using effect of the bed curtain can be improved. Of course, the transverse beam frame 110 may also be straight and disposed flat, which on the one hand facilitates ease of manufacture and on the other hand is more aesthetically pleasing.

In this embodiment, the transverse beam 110 is provided with a plurality of curtain connectors for connecting to the curtains. Thus, the bed curtain can be better and more conveniently installed, and the bed curtain can be more conveniently disassembled.

In addition, in order to further improve the safety of the portable bed curtain frame, the portable bed curtain frame can be designed as follows: the transverse beam frame 110 is contracted first, and then the transverse beam frame 110 and the longitudinal support frame 120 are folded with each other. This can be achieved here with an interlocking mechanism: when the transverse beam frame 110 extends and is abutted against the longitudinal support frame 120, the interlocking mechanism is locked, so that the sliding rod 151 cannot enter the arc track (or the fold track) and can only be positioned in the reverse clamping guide rail 1522; after the transverse beam frame 110 is contracted, the interlocking mechanism is opened, so that the sliding rod 151 can enter the circular arc track (or the zigzag track) under the action of external force, and the mutual folding between the transverse beam frame 110 and the longitudinal support frame 120 is realized. Therefore, the difficulty that the transverse beam frame 110 and the longitudinal support frame 120 are mutually abutted and changed into a mutually folded state under the unexpected condition can be improved, and the personnel are prevented from being accidentally stricken (the transverse beam frame 110 smashes the body of the person when being deformed) so as to improve the safety of the portable bed curtain frame.

Referring to fig. 6, fig. 6 is a schematic view illustrating the portable bed curtain frame 100 provided in the embodiment of the present application being contracted and folded. To effect the retraction of the portable bed curtain frame 100, the telescoping end 111 of the transverse beam 110 may be moved toward the folding end 112 such that the telescoping end 111 partially or fully nests within the folding end 112 to effect the retraction of the transverse beam 110.

The portable curtain frame 100 after the transverse beam 110 is contracted is shown in fig. 7 to 10: fig. 7 is a perspective view of a portable bed curtain frame 100 provided in the embodiment of the present application in a second state; fig. 8 is a front view of a portable bed curtain frame 100 in a second state according to the embodiment of the present application; fig. 9 is a left side view of a portable bed curtain frame 100 in a second state according to the embodiment of the present application; fig. 10 is a top view of a portable bed curtain frame 100 in a second state according to an embodiment of the present application.

After completion of the contraction of the lateral beam frames 110, the lateral beam frames 110 and the longitudinal support frames 120 can be folded, and the longitudinal support frames 120 can be folded.

Illustratively, the transverse beam frame 110 (or the folding end 112) can be lifted and moved a short distance to make the sliding rod 151 enter the circular arc track (or the zigzag track), and then the transverse beam frame 110 (or the folding end 112) is put down to make the sliding rod 151 run along the circular arc track (or the zigzag track) until the transverse beam frame 110 (or the folding end 112) naturally sags under the action of gravity and is stacked on one side of the longitudinal support frame 120.

For example, the folding of the longitudinal support frame 120 may be performed by folding the support rod along the folding path of the folding unit 1213, such that the portion of the first end 1211 and the portion of the second end 1212 are overlapped with each other.

The folding of the transverse beam 110 and the longitudinal support frame 120 and the folding of the longitudinal support frame 120 itself are completed, and then the folding of the portable bed curtain frame 100 is completed, and the portable bed curtain frame 100 is as shown in fig. 11 to 14. Fig. 11 is a perspective view of a portable bed curtain frame 100 provided in the embodiment of the present application in a third state; fig. 12 is a front view of a portable bed curtain frame 100 in a third state according to the embodiment of the present application; fig. 13 is a left side view of a portable bed curtain frame 100 in a third state according to the embodiment of the present application; fig. 14 is a top view of a portable bed curtain frame 100 in a third state according to an embodiment of the present application.

Therefore, the portable bed curtain frame 100 after being folded is very small in size and occupies a small space; and the use is convenient, and the installation, the disassembly and the bundling of the portable bed curtain frame 100 are very simple and easy to operate.

In summary, the present embodiment provides a portable curtain frame 100, which includes a transverse beam frame 110 (for supporting the outline of the curtain), a longitudinal support frame 120 (for supporting the transverse beam frame 110), and a fixing hook 130, wherein the transverse beam frame 110 is connected with the longitudinal support frame 120 in a rotation-limiting manner (indicating that the transverse beam frame 110 and the longitudinal support frame 120 are abutted or folded with each other by relative rotation between the transverse beam frame 110 and the longitudinal support frame 120). The fixing hooks 130 (for hooking the bed frame) are connected to the longitudinal support frame 120, and the fixing hooks 130 and the transverse beam frame 110 are respectively located at two ends of the longitudinal support frame 120, so that the portable curtain frame 100 and the bed frame are fixed. The bed curtain frame is simple in structure and convenient to use, can be made of metal materials or other materials with hard texture, is very light and small, and can well guarantee quality. When the bed curtain frame is not used, the transverse beam frame 110 and the longitudinal support frame 120 can be mutually folded, so that the portable bed curtain frame 100 can be folded, and the portable bed curtain frame is small in size and small in occupied space. When the transverse beam frame 110 and the longitudinal support frame 120 are abutted against each other, a first included angle between the transverse beam frame 110 and the longitudinal support frame 120 is within 90-120 degrees, after the transverse beam frame 110 and the longitudinal support frame 120 are folded with each other, the transverse beam frame 110 is stacked on one side of the longitudinal support frame 120, and a second included angle between the fixing hook 130 and the longitudinal support frame 120 is within 75-90 degrees. This allows the curtain to be hung on the transverse beam 110, and the fixing hooks 130 to be fixed to the frame, thereby ensuring the stability of the installation of the portable curtain frame 100 on the frame. In addition, a first included angle between the transverse beam frame 110 and the longitudinal support frame 120 is within 90-120 degrees, and a second included angle between the fixing hook 130 and the longitudinal support frame 120 is within 75-90 degrees, so that the gravity center of the bed curtain frame is more deviated to the position of the longitudinal support frame 120, and the stability and the reliability of the portable bed curtain frame 100 are further improved. During the process of installing the curtain frame, the curtains can be installed together, for example, the curtains can be installed on the transverse beam frame 110 before the transverse beam frame 110 is extended, so that the curtains can be driven to move together when the transverse beam frame 110 is extended, and the installation of the curtains can be completed very conveniently and quickly.
