Description

Technical Field

[0001] This application relates to the field of children's products technology, and more particularly to a children's bed. Background Technology

[0002] A children's bed provides a space for children to sleep or play. Children's beds can be folded for storage to improve their convenience. However, current technology still results in a relatively large overall size when folded, taking up considerable space and hindering transportation and storage.

[0003] Therefore, improvements to existing technologies are necessary. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art by providing a children's bed.

[0005] According to one aspect of this application, a children's bed is provided, including a bed frame, support legs, and a railing assembly; the bed frame includes two bed bodies arranged sequentially along the X-axis and hinged to each other, each bed body having a lifting rod, the lifting rod having a sliding groove, and when the children's bed is in an unfolded state, the sliding groove extends along the X-axis; the support legs are slidably connected to the sliding groove via connecting pins; and the railing assembly is connected between adjacent support legs.

[0006] In one embodiment, when the children's bed is in an unfolded configuration, the connecting pin is located at the end of the sliding groove away from the two bed frame hinges; the children's bed also includes a locking structure configured to optionally restrict the connecting pin at the end of the sliding groove away from the two bed frame hinges.

[0007] In one embodiment, the locking structure includes a locking block, a return spring, and a switching block; when the crib is in the unfolded state, the locking block is pressed against the connecting pin by the return spring to limit the relative position between the connecting pin and the sliding groove; the switching block is configured to drive the locking block so that the locking block can be selectively pressed against the connecting pin.

[0008] In one embodiment, the locking block and the switching block are connected to the lifting rod via a mounting base. When the children's bed is in the unfolded state, the locking block and the switching block are respectively connected to both sides of the mounting groove in the Z-axis direction. When the children's bed is in the unfolded state, one end of the locking block is hinged to the mounting base and the other end is pressed against the connecting pin. One end of the switching block abuts against the locking block and the other end extends to the outside of the lifting rod. The switching block is configured to selectively drive the end of the locking block near the connecting pin to rotate.

[0009] In one embodiment, the end of the switching block that abuts against the locking block is arranged in a Λ shape.

[0010] In one embodiment, the end of the mounting base away from the lifting rod is provided with a limiting part. When the children's bed is in the unfolded state, the top of the limiting part is pressed against a limiting rod, and the limiting rod is connected to the support leg.

[0011] In one embodiment, four support legs are provided, with two support legs connected to the end of the same bed frame away from the hinge point of the two bed frames; the connecting pin is disposed on the support leg through a connecting seat, and the connecting seat is connected to two support legs on the same bed frame.

[0012] In one embodiment, the bed has a connecting beam and side beams arranged opposite each other in the Y-axis direction, the connecting beam overlapping two side beams in the same bed, and the lifting rod is one of the side beams.

[0013] In one embodiment, the connecting pin is disposed on the support leg via a connecting seat; the portion of the side beam with the sliding groove is connected to the connecting beam via a connector, the connector including a connecting part and a clearance part that are interconnected; when the children's bed is in the unfolded state, the connecting part is connected to the bottom of the side beam, the clearance part is disposed opposite to the side beam and the clearance part is spaced apart from the side beam in the Y-axis direction, and the connecting beam is connected to the end of the clearance part away from the connecting part.

[0014] In one embodiment, a protective sleeve is fitted at the bottom of the support leg, and a crimping block is provided on the protective sleeve. The middle part of the crimping block is hinged to the protective sleeve, and a compression spring is connected between one end of the crimping block and the protective sleeve. The compression spring is configured to press the other end of the crimping block onto the support leg.

[0015] The beneficial effects of this application are as follows: the support legs are slidably connected in the sliding groove via connecting pins, and the lifting rod can rotate around the support legs. When the children's bed switches from the unfolded form to the folded form, the two bed frames that are hinged to each other fold together and move closer to each other, that is, the lifting rods on the two bed frames move closer to each other, and the support legs connected to the lifting rods also move closer to each other, reducing the volume occupied by the children's bed in the X-axis direction. At the same time, the sliding groove on the lifting rod rotates from the X-axis direction to the Z-axis direction. During the rotation of the lifting rod (bed frame), the connecting pin slides in the sliding groove, that is, the bed frame moves relative to the support legs along the extension direction of the sliding groove, reducing the height of the children's bed in the folded form (the dimension in the Z-axis direction), which is conducive to reducing the size of the children's bed and facilitating the transportation and storage of the children's bed.

[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0042] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0043] The children's bed in this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] In the current technology, the overall volume of children's beds is still relatively large when folded, taking up a lot of space, which is not conducive to the transportation and storage of children's beds.

[0045] To address the aforementioned technical problems, this application provides a children's bed, including a bed frame, support legs, and a railing assembly. The bed frame comprises two bed sections arranged sequentially along the X-axis and hinged to each other. Each bed section has a lifting rod with a sliding groove. When the children's bed is in its unfolded state, the sliding groove extends along the X-axis. The support legs are slidably connected to the sliding groove via connecting pins. The railing assembly is connected between adjacent support legs. This will be described in detail below.

[0046] See Figure 1 and Figure 2 The children's bed includes a bed frame 10, support legs 20, and a railing assembly 30. The bed frame 10 includes two bed bodies 11 arranged sequentially along the X-axis and hinged to each other. The bed body 11 has a lifting rod 111, and the lifting rod 111 has a sliding groove 1111. When the children's bed is in the unfolded state, the sliding groove 1111 extends along the X-axis. The support legs 20 are slidably connected to the sliding groove 1111 by connecting pins 90. The railing assembly 30 is connected between adjacent support legs 20.

[0047] The support leg 20 is slidably connected to the sliding groove 1111 via the connecting pin 90. The lifting rod 111 can rotate around the support leg 20 (the connecting pin 90 can rotate in the sliding groove 1111). When the children's bed is switched from unfolded to folded, the two bed frames 11 that are hinged to each other are folded together and brought closer to each other. That is, the lifting rods 111 on the two bed frames 11 are brought closer to each other, and the support leg 20 connected to the lifting rod 111 is also brought closer to each other, which reduces the volume occupied by the children's bed in the X-axis direction and reduces the transportation and storage space.

[0048] As the two bed frames 11 move closer together, the sliding groove 1111 on the lifting rod 111 rotates from the X-axis direction to the Z-axis direction. During the rotation of the lifting rod 111 (bed frame 11), the connecting pin 90 slides in the sliding groove 1111, that is, the bed frame 11 moves relative to the support leg 20 along the extension direction of the sliding groove 1111, which reduces the height (dimension in the Z-axis direction) of the children's bed when it is folded, which is conducive to reducing the volume of the children's bed frame 11 and making it easier to transport and store the children's bed.

[0049] It should be noted that in this embodiment, when the children's bed is in the unfolded state, the bed frame 10 is horizontal, that is, the two bed bodies 11 are horizontal. In some embodiments, it may not be horizontal, but the stability of the bed frame 10 when the children's bed is in the unfolded state must be ensured, which will not be elaborated here. When the children's bed is in the folded state, the two bed bodies 11 are folded in half. By hinged at one end of bed body 11a to the other bed body 11b, and by the cooperation of the connecting pin 90 and the sliding groove 1111 at the other end of bed body 11a, the dimensions of the children's bed in the X-axis direction and the Z-axis direction are reduced after the children's bed is folded, thereby reducing the area occupied by the children's bed body 11.

[0050] In some embodiments, the support rod assembly 30 includes a connecting block 31 and an upper support rod 32 and a lower support rod 33 disposed on opposite sides of the connecting block 31. When the children's bed is changing its form (switching between unfolded and folded forms), it can ensure the stability of the support leg 20 and prevent the support leg 20 from having too much freedom, which would affect the efficiency of the form changing. This will not be elaborated further here.

[0051] In some embodiments, when the children's bed is in the unfolded position, the connecting pin 90 is located at the end of the sliding groove 1111 away from the hinge of the two bed frames 11; the children's bed also includes a locking structure 40 configured to optionally restrict the connecting pin 90 at the end of the sliding groove 1111 away from the hinge of the two bed frames 11.

[0052] By setting the locking structure 40, the relative position between the connecting pin 90 and the sliding groove 1111 can be restricted. When the children's bed switches from the unfolded form to the folded form, the two bed bodies 11 fold and move closer together. During the rotation of the two bed bodies 11, the locking structure 40 restricts the connecting pin 90 to the end of the sliding groove 1111 away from the hinge of the two bed bodies 11. That is, during the rotation of the bed body 11, the connecting pin 90 will not slide along the sliding groove 1111. In other words, the bed body 11 will only rotate relative to the support leg 20 and will not slide relative to the support leg 20. After the bed body 11 rotates to the predetermined position (the folding of the children's bed is completed in the X-axis direction), the locking structure 40 is released from the restriction on the connecting pin 90, so that the connecting pin 90 slides in the sliding groove 1111, that is, the bed body 11 slides relative to the support leg 20, thereby reducing the height of the children's bed.

[0053] By setting the locking structure 40, the folding operation of the crib in the X-axis direction is separated from the folding operation in the Z-axis direction (e.g., Figure 5-13 First, perform the folding operation along the X-axis to position the crib. Figure 6 Then, perform the folding operation along the Z-axis until the crib is in the correct position. Figure 10 The shape avoids a high degree of freedom between the bed frame 11 and the support legs 20, reducing the difficulty of folding and closing the children's bed.

[0054] It is worth mentioning that when the children's bed is switched from the folded form to the unfolded form, the bed body 11 is first moved upward, and the connecting pin 90 slides in the sliding groove 1111. After the bed body 11 is moved upward to the set position, the connecting pin 90 is restricted to the end of the sliding groove 1111 away from the hinge of the two bed bodies 11 by the locking structure 40, which can prevent the bed body 11 from moving in the Z-axis direction. Then the two folded bed bodies 11 are unfolded until the children's bed is in the unfolded form.

[0055] It should be noted that the locking structure 40 can selectively restrict the connecting pin 90 at the end of the sliding groove 1111 away from the hinge of the two bed bodies 11. That is, the locking structure 40 can freely switch states according to the usage requirements to restrict or unlock the connecting pin 90.

[0056] See Figure 2-5 The locking structure 40 includes a locking block 41, a return spring 42, and a switching block 43. When the children's bed is in the unfolded state, the locking block 41 is pressed against the connecting pin 90 by the return spring 42 to limit the relative position between the connecting pin 90 and the sliding groove 1111. The switching block 43 is configured to drive the locking block 41 so that the locking block 41 can be selectively pressed against the connecting pin 90.

[0057] By limiting the connecting pin 90 with the locking block 41, the connecting pin 90 can be restricted to the end of the sliding groove 1111 away from the hinge of the two bed bodies 11, preventing the connecting pin 90 from sliding relative to the sliding groove 1111 during the rotation of the bed body 11, thus reducing the difficulty of folding and closing the children's bed. For a detailed analysis, please refer to the aforementioned embodiment, which will not be repeated here. The setting of the return spring 42 can ensure the stability of the locking block 41 pressing on the connecting pin 90, and improve the stability of the children's bed in the Z-axis direction during the transformation of the children's bed.

[0058] When the child bed needs to be folded or closed in the Z-axis direction, the locking block 41 is driven away from the connecting pin 90 by the switching block 43. At this time, the return spring 42 is in a compressed state. After the connecting pin 90 is released from its restriction, it slides in the sliding groove 1111, realizing the folding or closing operation of the child bed in the Z-axis direction. When the force on the switching block 43 is released, the locking block 41 is reset under the action of the return spring 42.

[0059] The locking block 41 and the switching block 43 are connected to the lifting rod 111 via the mounting base 44. When the children's bed is in the unfolded state, the locking block 41 and the switching block 43 are respectively connected to the two sides of the mounting groove in the Z-axis direction. When the children's bed is in the unfolded state, one end of the locking block 41 is hinged to the mounting base 44 and the other end is pressed against the connecting pin 90. One end of the switching block 43 abuts against the locking block 41 and the other end extends to the outside of the lifting rod 111. The switching block 43 is configured to selectively drive the end of the locking block 41 near the connecting pin 90 to rotate.

[0060] When the crib is in its unfolded position, one end of the locking block 41 is hinged to the mounting base 44 (the portion of the mounting base 44 located on one side of the sliding groove 1111), and the other end is pressed against the connecting pin 90. At this time, the locking block 41 is in an inclined state (e.g., Figure 5As shown, the locking block 41 restricts the connecting pin 90 from sliding in the sliding groove 1111; when the connecting pin 90 needs to slide in the sliding groove 1111, the locking block 41 is lifted near the end of the connecting pin 90 by the switching block 43, thereby releasing the restriction of the locking block 41 on the connecting pin 90, so that the connecting pin 90 can slide in the sliding groove 1111.

[0061] It is worth mentioning that by setting the mounting base 44, the locking block 41 and the switching block 43 can be first assembled on the mounting base 44, and then the mounting base 44 can be installed on the lifting rod 111, which improves the assembly efficiency and reduces the assembly difficulty.

[0062] It should be noted that when the switching block 43 lifts the end of the locking block 41, the connecting pin 90 slides along the sliding groove 1111 to the top of the locking block 41 (to... Figure 9 (Taking the perspective as an example, the same applies below), then reset the switching block 43 to avoid the switching block 43 interfering with the subsequent sliding of the connecting pin 90.

[0063] In some embodiments, the switching block 43 can be reset by a spring or by manually pulling the switching block 43 to prevent the switching block 43 from blocking the sliding groove 1111 and affecting the sliding of the connecting pin 90 in the sliding groove 1111. In some embodiments, the end of the switching block 43 that abuts against the locking block 41 is arranged in a Λ shape. When the connecting pin 90 slides to the end of the switching block 43, it abuts against the inclined surface, which can realize the automatic reset of the switching block 43 without manual intervention, thus preventing the switching block 43 from blocking the sliding groove 1111 and affecting the sliding of the connecting pin 90 in the sliding groove 1111. When the connecting pin 90 slides past the switching block 43 (the connecting pin 90 slides above the switching block 43), the locking block 41 is reset under the action of the reset spring 42.

[0064] When the children's bed switches from its folded to its unfolded state, the bed body 11 is first pulled upward along the Z-axis. During the lifting of the bed body 11, the connecting pin 90 moves downward relative to the sliding groove 1111. When the connecting pin 90 moves to abut against the locking block 41, the locking block 41 is pressed. The connecting pin 90 continues to move until it reaches the bottom of the sliding groove 1111. At this time, the locking block 41 is reset under the action of the return spring 42 and presses against the connecting pin 90, thereby limiting the connecting pin 90 and completing the unfolding operation of the children's bed in the Z-axis direction. Then, the unfolding operation of the children's bed in the X-axis direction is performed, which will not be described in detail here.

[0065] See Figure 5 The mounting base 44 is provided with a limiting part 441 at the end away from the lifting rod 111. When the children's bed is in the unfolded state, the top of the limiting part 441 is pressed against the limiting rod 80, and the limiting rod 80 is connected to the support leg 20.

[0066] In this embodiment, when the children's bed is in the unfolded state, the bed frame 10 is in the unfolded state. By setting the limiting rod 80, the lifting rod 111 (bed body 11) can be prevented from rotating downward, that is, the hinge joint of the two bed bodies 11 is prevented from collapsing downward, thus improving the stability of the children's bed in the unfolded state.

[0067] In some embodiments, four support legs 20 are provided, and two support legs 20 are connected to the end of the same bed 11 away from the hinge of the two bed 11; the connecting pin 90 is provided on the support leg 20 through the connecting seat 50, and the connecting seat 50 is connected to the two support legs 20 on the same bed 11.

[0068] By using the connecting seat 50, the two support legs 20 on the same bed frame 11 are connected as one unit. When the children's bed is folded or unfolded, the two support legs 20 can be folded or unfolded at the same time, which improves the convenience of changing the form of the children's bed. In addition, the connecting seat 50 improves the overall strength of the children's bed and enhances the stability of the children's bed during use.

[0069] In some embodiments, the bed body 11 has a connecting beam 112 and side beams 113 arranged opposite each other in the Y-axis direction. The connecting beam 112 overlaps the two side beams 113 in the same bed body 11, and the lifting rod 111 is a side beam 113.

[0070] Using the side beam 113 of the bed frame 11 as a lifting rod 111 avoids the need for additional lifting rods 111, reduces the weight of the bed frame 11, and improves the convenience of changing the form of the children's bed.

[0071] In some embodiments, the connecting pin 90 is disposed on the support leg 20 via the connecting seat 50; the portion of the side beam 113 with the sliding groove 1111 is connected to the connecting beam 112 via the connecting member 60, the connecting member 60 including a connecting part 61 and a clearance part 62 connected to each other; when the children's bed is in the unfolded state, the connecting part 61 is connected to the bottom of the side beam 113, the clearance part 62 is disposed opposite to the side beam 113, and the clearance part 62 is spaced apart from the side beam 113 in the Y-axis direction, and the connecting beam 112 is connected to the end of the clearance part 62 away from the connecting part 61.

[0072] The clearance portion 62 is spaced apart from the side beam 113, providing clearance space for the connecting seat 50. When the connecting pin 90 slides in the sliding groove 1111, the clearance space ensures that the connecting beam 112 will not affect the relative sliding of the connecting pin 90 (connecting seat 50), which is beneficial for the folding operation of the children's bed in the Z-axis direction.

[0073] In addition, by setting the connecting beam 112 at the end of the avoidance part 62 away from the connecting part 61, that is, when the children's bed is in the unfolded state, the connecting beam 112 and the side beam 113 are basically the same height, which improves the flatness of the bed 11 and thus improves the comfort of the children's bed.

[0074] See Figure 14 The bottom of the support leg 20 is fitted with a protective sleeve 70, and the protective sleeve 70 is provided with a crimping block 71. The middle part of the crimping block 71 is hinged to the protective sleeve 70, and a compression spring 72 is connected between one end of the crimping block 71 and the protective sleeve 70. The compression spring 72 is configured to press the other end of the crimping block 71 onto the support leg 20.

[0075] A compression spring 72 is provided at one end of the pressing block 71, so that the other end of the pressing block 71 is pressed against the support leg 20, which improves the stability of the protective sleeve 70 on the support leg 20. When it is necessary to remove the protective sleeve 70, press the end of the pressing block 71 with the compression spring 72, so that the end of the pressing block 71 pressed against the support leg 20 is separated from the support leg 20, thus realizing the removal of the anti-slip sleeve. The structure is simple and easy to use.

[0076] In some embodiments, the end of the crimping block 71 that is crimped with the support leg 20 is gear-shaped, which can increase the static friction between it and the support leg 20 and improve the stability of the anti-slip sleeve installation.

[0077] The technical solution provided in this application aims to allow the support leg 20 to slide in the sliding groove 1111 via the connecting pin 90, enabling the lifting rod 111 to rotate around the support leg 20. When the children's bed switches from the unfolded form to the folded form, the two bed bodies 11, which are hinged to each other, fold in half and move closer together. That is, the lifting rods 111 on the two bed bodies 11 move closer together, and the support leg 20 connected to the lifting rod 111 also moves closer together, reducing the volume occupied by the children's bed in the X-axis direction. At the same time, the sliding groove 1111 on the lifting rod 111 rotates from the X-axis direction to the Z-axis direction. During the rotation of the lifting rod 111 (bed body 11), the connecting pin 90 slides in the sliding groove 1111, that is, the bed body 11 moves relative to the support leg 20 along the extension direction of the sliding groove 1111, reducing the height (dimension in the Z-axis direction) of the children's bed in the folded form. This is beneficial for reducing the volume of the children's bed body 11 and facilitating the transportation and storage of the children's bed.
