Description

Technical Field

[0001] This application relates to the field of bed design, and in particular to a children's bed and its operation method. Background Technology

[0002] Existing children's beds are mainly used to confine infants inside, thereby providing a safe play space and sleep space.

[0003] The existing children's bed frame is extremely inconvenient to disassemble after use. It requires using a screwdriver to remove the bolts at the frame joints, and the removed bolts and frame joints are easily lost during storage, affecting the normal installation and use of the play bed later.

[0004] To address this issue, unused children's beds can be folded up for storage. However, these folding beds have limited internal space and very limited usage scenarios; their unfolded state is also unstable, often wobbling or easily deforming, making safety difficult to guarantee; furthermore, the unfolding and folding process is not flexible. Summary of the Invention

[0005] Therefore, it is necessary to provide a children's bed and its operation method to address at least some of the problems mentioned above.

[0006] A children's bed, comprising:

[0007] The push-to-unlock handrail includes a joint connector and two side bars located on both sides of the joint connector. The ends of the two side bars that are close to each other are rotatably connected to the joint connector through a locking mechanism, and the ends of the side bars that are far apart from each other are rotatably connected to the mounting sleeve.

[0008] Multiple support bases are located below each of the aforementioned mounting sleeves and are each connected to the mounting sleeve via a vertical pole;

[0009] The lifting base is located in the middle of the bottom of the children's bed and is hinged to each of the support seats by connecting rods;

[0010] The railings are curved rods. When the children's bed is unfolded, all the railings are basically in the same plane, so that when the children's bed is unfolded, each railing is locked with the joint connector and forms a circular fence. When the children's bed is closed, the two railings are unlocked from the joint connector and rotate around the connection point with the joint connector and gradually fold closer together.

[0011] In some embodiments, the children's bed further includes a canopy, the canopy comprising:

[0012] The connecting block is located in the middle position above each mounting sleeve;

[0013] Support rods are provided for each mounting sleeve, with one end of each support rod inserted into the mounting sleeve and the other end hinged to the connecting block.

[0014] In some embodiments, the joint connector has a curved arc and two first strip-shaped holes on its surface;

[0015] The locking mechanism includes:

[0016] A lock head is located at one end of the railing that extends into the joint connector, and the lower side of the lock head is a limiting and locking edge;

[0017] An unlock button is inserted into the joint connector from below. The surface of the unlock button has two second strip-shaped holes. The distance between the two second strip-shaped holes gradually decreases from top to bottom, and each corresponds to the position of a first strip-shaped hole.

[0018] There are two locking pins, which pass through a set of first and second strip holes respectively, thereby connecting the joint connector to the unlocking button.

[0019] In the locked state, the locking pin is positioned at a location where the two first slots are far apart from each other, and is located above the second slot, with the locking pin abutting against the limiting locking edge of the lock head;

[0020] In the unlocked state, the unlock button is pressed upwards, causing the wall of the second strip hole to drive the lock pin to move to a position where the two first strip holes are close to each other, and at the lower part of the second strip hole, thereby separating it from the lock head and making its rotation trajectory not coincide with that of the lock head.

[0021] In some embodiments, the locking mechanism further includes a spring disposed within the joint connector;

[0022] One end of the spring is fixed to the inner wall of the joint connector, and the other end is connected to the top surface of the unlock button. It is used to compress and store elastic potential energy when the unlock button is pressed upward, and to restore its length and push the unlock button downward to reset when the unlock button is released.

[0023] In some embodiments, the upper surface of the lock head is a convex arc-shaped edge, which is used to slide relative to the circumferential surface of the locking pin when the retaining rod is reset from the unlocked state to the locked state, and drive the locking pin to move toward the part of the first strip hole that is close to each other, so that the lock head reaches the locked position.

[0024] In some embodiments, the unlock button surface is provided with guide blocks extending vertically, the guide blocks are embedded in guide grooves extending vertically within the joint connector, and can move along the length direction of the guide grooves.

[0025] A method for operating a children's bed includes:

[0026] The children's bed is unfolded and locked.

[0027] When folding the bed frame, press the unlock button to unlock the railings;

[0028] Hold the lifting base with your hand and lift it upwards. Multiple support seats will simultaneously move closer to the lifting base and retract. At this time, multiple uprights will be pulled inwards. When the uprights retract inwards, the upper part of the uprights will squeeze the surrounding rod through the mounting sleeve, causing it to rotate and fold downwards. At the same time, the joint connectors will gradually fall down under the inward action of the uprights.

[0029] When the lifting base is raised to its highest position, the joint connectors and the surrounding rods are lowered to their lowest positions, and the entire bed is folded and retracted.

[0030] The aforementioned children's beds have at least the following beneficial technical effects:

[0031] (1) When the children's bed in this embodiment is unfolded, all the surrounding rods are basically in the same plane (the included angle between adjacent surrounding rods is a flat angle or slightly less than 180 degrees). The detachable support base plate is laid on the surface of the lifting base and each connecting rod group when the bed is unfolded, so that it can cooperate with the surrounding uprights and the upper surrounding rods to form a cylindrical space to accommodate children. It can be disassembled and removed when not in use. The circular fence, together with the surrounding uprights and the lower detachable support base plate, forms a cylindrical space. Compared with conventional children's beds, the space is larger and can accommodate multiple children, meeting the needs of more usage scenarios.

[0032] (2) When the bed is in the locked state, the bed can be firmly locked. The relative position between the railing and the joint connector is stable and firm, and there will be no shaking or easy folding and deformation, which can ensure safe use.

[0033] The children's bed in this embodiment can be flexibly deformed and folded after unlocking. The connecting rod assembly is hinged to the lifting base and support seat respectively, which facilitates linkage and enables the flexible unfolding and folding of the bed. Because the bed can be easily deformed, it does not require a lot of effort to compress the bed, thereby avoiding breakage of the rods or wear at the connecting parts due to excessive force.

[0062] like Figures 1-7 As shown, this application provides a children's bed, including:

[0063] Multiple mounting sleeves 10 are provided, and a press-to-unlock handle is provided between adjacent mounting sleeves 10. The press-to-unlock handle includes a joint connector 20 and two rails 30 located on both sides of the joint connector 20. The ends of the two rails 30 that are close to each other are rotatably connected to the joint connector 20 through a locking mechanism, and the ends of the rails 30 that are far from each other are rotatably connected to the mounting sleeve 10.

[0064] Multiple support bases 70 are provided below each of the mounting sleeves 10 and are each connected to the mounting sleeve 10 by a vertical pole 60;

[0065] The lifting base 90 is located in the middle position under the children's bed and is hinged to each of the support seats 70 through the connecting rod assembly 80;

[0066] A detachable load-bearing base plate 100 is laid on the surface of the lifting base 90 and each connecting rod assembly 80;

[0067] The railing 30 is a curved rod. When unfolded, each railing 30 is basically in the same plane, so that when the children's bed is unfolded, each railing 30 locks with the joint connector 20 and forms a circular fence. When the children's bed is folded, the two railings 30 are unlocked from the joint connector 20 respectively and rotate around the connection point with the joint connector 20 and gradually fold closer together.

[0068] refer to Figure 5 When folding the bed frame, first press the unlock button 40 to unlock the surrounding rod 30; hold the lifting base 90 with your hand and lift it upwards. Multiple support seats 70 will simultaneously move closer to the lifting base 90 and retract. At this time, all four uprights 60 will be pulled inwards. When the uprights 60 retract inwards, the upper part of the uprights 60 will squeeze the surrounding rod 30 through the mounting sleeve 10, causing it to rotate and fold downwards. At the same time, the joint connector 20 will gradually fall down under the inward action of the uprights 60.

[0069] When the lifting base 90 is raised to its highest position, the joint connector 20 and the surrounding rod 30 are lowered to their lowest positions, and the entire bed is folded and retracted.

[0070] When the folding bed in this embodiment is unfolded, all the surrounding rods 30 are basically in the same plane (the included angle between adjacent surrounding rods 30 is a flat angle or slightly less than 180 degrees). The detachable support base plate 100 is laid on the surface of the lifting base 90 and each connecting rod group 80 when the bed is unfolded, so that it can cooperate with the surrounding uprights 60 and the upper surrounding rods 30 to form a cylindrical space to accommodate children. It can be disassembled and removed when not in use. The circular fence, together with the surrounding uprights 60 and the lower detachable support base plate 100, forms a cylindrical space, which is larger than a conventional children's bed and can accommodate multiple children, meeting the needs of more usage scenarios.

[0071] When the bed is in the unfolded and locked state, it can be firmly locked. The relative position between the surrounding rod 30 and the joint connector 20 is stable and secure, and there will be no shaking or easy folding or deformation, which can ensure safe use.

[0072] The children's bed in this embodiment can be flexibly deformed and folded after being unlocked. The connecting rod assembly 80 is hinged to the lifting base 90 and the support seat 70 respectively, which facilitates linkage and enables the flexible unfolding and folding of the bed. Since the bed can be easily deformed, it does not require a lot of effort to compress the bed, thereby avoiding breakage of the rods or wear at the connecting parts due to excessive force.

[0073] refer to Figure 1 In some embodiments, the folding bed further includes a canopy, the canopy comprising:

[0074] Connecting block A is located at the middle position above each mounting sleeve 10;

[0075] Support rods B are provided for each mounting sleeve 10, with one end of the support rods B inserted into the mounting sleeve 10 and the other end hinged to the connecting block A.

[0076] Specifically, each mounting sleeve 10 is fixedly connected to the connecting block A above by a support rod B. When the connecting block A and the support rod B are opened, a canopy is formed by covering the surface with fabric, thereby protecting the enclosed cylindrical space. Furthermore, since the support rod B is inserted into the mounting sleeve 10, when not in use, each support rod B can be separated from the mounting sleeve 10 and stored folded up with the connecting block A as the center. This allows the folding bed to be used in an open-top state, further expanding its usage scenarios.

[0077] In addition, the canopy structure also helps to enhance the stability and firmness of the relative positions of each mounting sleeve 10 when the bed is unfolded, thereby strengthening the reinforcement and locking of the bed in the unfolded state, ensuring that the upper railing will not shake or deform, and fully guaranteeing safety in use.

[0078] like Figures 1-7 As shown, in some embodiments, the joint connector 20 has a curved arc and two first strip holes 21 are provided on its surface;

[0079] The locking mechanism includes:

[0080] A lock head is provided at the end of the railing 30 that extends into the joint connector 20, and the lower side of the lock head 32 is a limiting locking edge 32a;

[0081] Unlock button 40 is inserted into joint connector 20 from below. The surface of unlock button 40 is provided with two second strip holes 41. The distance between the two second strip holes 41 gradually decreases from top to bottom, and each corresponds to the position of a first strip hole 21.

[0082] There are two locking pins 50. The two locking pins 50 pass through a set of first strip holes 21 and second strip holes 41 corresponding to the position, so that the joint connector 20 is connected to the unlocking button 40.

[0083] In the locked state, the locking pin 50 is positioned at the location where the two first strip holes 21 are far apart from each other, and is located above the second strip hole 41, and the locking pin 50 abuts against the limiting locking edge 32a of the lock head 32.

[0084] In the unlocked state, the unlock button 40 is pressed upward, causing the wall of the second strip hole 41 to drive the locking pin 50 to move to a position where the two first strip holes 21 are close to each other, and at the same time, it is located at the lower part of the second strip hole 41, thereby separating it from the lock head 32 and not coinciding with the rotation trajectory of the lock head 32.

[0085] Specifically, the railing 30 is connected to the joint connector 20 via a connecting pin 31. In the locked state, the locking pin 50 is positioned at the point where the two first slots 21 are far apart from each other, and is located above the second slot 41. The locking pin 50 abuts against the limiting locking edge 32a of the lock head 32. At this time, the railing 30 cannot rotate freely, and its relative position with the joint connector 20 remains unchanged. When unlocking is required, the unlocking button 40 is pressed upwards. As the unlocking button 40 moves upwards, the wall of the second slot 41 applies force to the locking pin 50, driving the locking pin 50 to move towards the point where the two first slots 21 are close to each other, and simultaneously to the lower part of the second slot 41, thereby separating from the lock head 32 and not coinciding with the rotation trajectory of the lock head 32. At this time, the railing 30 can be rotated and folded.

[0086] In this embodiment, the joint connector is designed to adapt to the shape of the curved rod, thereby locking with the curved rod and forming a standard circular fence.

[0087] In this embodiment, the locking mechanism achieves convenient locking between the railing 30 and the joint connector 20 by abutting the locking pin 50 against the limiting locking edge 32a of the lock head 32. This ensures a secure lock on the bed when it is unfolded. When the bed is unfolded and in use, the relative position between the railing 30 and the joint connector 20 is stable and secure in the locked state, preventing shaking or easy folding or deformation, thus ensuring safe use. Unlocking is achieved simply by pressing the unlock button 40, making operation convenient and quick. When unlocking is required, pressing the unlock button 40 drives the locking pin 50 to separate from the lock head 32, and prevents the rotation trajectories of the locking pin 50 and the lock head 32 from coinciding. This converts the vertical pressing force into a driving force that moves the locking pin 50 horizontally. The design is ingenious, the unlocking operation is simple and effortless, and the operation efficiency is high.

[0088] refer to Figure 2 and Figure 3 In some embodiments, the locking mechanism further includes a spring a disposed within the joint connector 20; one end of the spring a is fixed to the inner wall of the joint connector 20, and the other end is connected to the top surface of the unlock button 40, for compressing and accumulating elastic potential energy when the unlock button 40 is pressed upward, and restoring its length and pushing the unlock button 40 downward to reset when the unlock button 40 is released.

[0089] Specifically, spring a can be compressed and shortened to store elastic potential energy when the unlock button 40 is pressed upward; when the unlock button 40 is released, it returns to its length and pushes the unlock button 40 downward to reset. Thus, the unlock button 40 is automatically and quickly reset after the unlocking action by spring a. After the reset, it can ensure the normal implementation of the next unlocking operation, thereby avoiding the situation where the next unlocking operation cannot be implemented due to the inability to reset normally. It also avoids the need to set up a separate reset mechanism, which occupies a small space, and avoids the trouble and slow operation of manual reset.

[0090] refer to Figure 2 In some embodiments, the upper side of the lock head 32 is a convex arc-shaped edge 32b, which is used to slide relative to the circumferential surface of the locking pin 50 when the retaining rod 30 is reset from the unlocked state to the locked state, and drive the locking pin 50 to move toward the part of the first strip hole 21 that is close to each other, so that the lock head 32 reaches the locked position.

[0091] Specifically, due to the spring a, after unlocking, the spring a drives the unlock button 40 to reset downwards, at which time the locking pin 50 also resets to the position of the limiting lock tongue; at this time, the locking pin 50 also falls on the rotation trajectory of the lock head 32. Since the upper side of the lock head 32 is provided with an outwardly convex arc-shaped edge 32b, when the retaining rod 30 resets from the unlocked state to the locked state, the outwardly convex arc-shaped edge 32b slides relative to the circumferential surface of the locking pin 50 and pushes the locking pin 50 to move closer to each other in the first strip hole 21, so that the lock head 32 can reach the locked position; when the outwardly convex arc-shaped edge 32b moves to the point where it does not contact the pushed-open locking pin 50, the locking pin 50 moves to the limiting locking edge 32a on the lower surface of the lock head 32 under the reverse driving action of the spring a and abuts against the lock head 32 to achieve locking.

[0092] In this embodiment, a convex arc-shaped edge 32b is provided on the upper side of the lock head 32, so that the folded railing 30 can be directly unfolded and rotated to the locking position and locked without the need for manual pressing of the unlock button 40 to allow the lock head 32 to make way for the railing 30 to return to the locking position. This saves operation steps and operation time, and makes the reset and locking of the railing 30 simpler and more convenient.

[0093] refer to Figure 2 and Figure 3 In some embodiments, the unlock button 40 has guide blocks 42 extending vertically on its surface. The guide blocks 42 are embedded in guide grooves extending vertically within the joint connector 20 and can move along the length of the guide grooves.

[0094] Specifically, when the unlock button 40 is pressed and moved upward, the guide groove can provide good guidance for the movement of the unlock button 40, avoid directional deviation of the movement of the unlock button 40, ensure the reliable and stable operation of the mechanism, and make the unlock button 40 move smoothly without jamming.

[0095] In the above description, although expressions such as "first" and "second" may be used to describe various elements of this application, they are not intended to limit the corresponding elements. For example, the above expressions are not intended to limit the order or importance of corresponding elements. The above expressions are used to distinguish one component from another.

[0096] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. Singular expressions include plural expressions unless there are significant differences in context or approach between them.

[0097] The above description is merely an exemplary embodiment of this application and is not intended to limit the scope of protection of this application. The scope of protection of this application is determined by the appended claims.

[0098] Those skilled in the art will understand that the technical features of the above embodiments can be omitted, added, or combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as the combination of these technical features does not contradict each other, and simple transformations that those skilled in the art can conceive of, as well as structural transformations that adapt to and functionally modify the prior art, should be considered within the scope of this specification.

[0099] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that although various embodiments have been shown and described with reference to this application, those skilled in the art can make various modifications and improvements in form and detail without departing from the concept of this application, and without departing from the scope of this application as defined by the appended claims. All such modifications and improvements fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.

The operating method according to claim 7, characterized in that, The process of pressing the unlock button to unlock the fence includes: pressing the unlock button upwards; as the unlock button moves upwards, the wall of the second strip-shaped hole applies force to the locking pin, driving the locking pin to move towards the part where the two first strip-shaped holes are close to each other, and at the same time moving to the lower part of the second strip-shaped hole, thereby separating from the lock head and not coinciding with the rotation trajectory of the lock head, and the fence is in the unlocked state.

10. The operating method according to claim 7, characterized in that, The children's bed is unfolded and locked, including: The convex arc edge slides relative to the circumferential surface of the locking pin and pushes the locking pin toward the part of the first strip hole that is close to each other, so that the lock head reaches the locked position; When the outwardly convex arc edge moves to a point where it no longer contacts the pushed-open locking pin, the locking pin moves to the limiting locking edge on the lower surface of the lock head under the reverse driving action of the spring and abuts against the lock head to achieve locking.
