A folding frame and bed

Abstract

This utility model relates to the field of pet bed technology, and in particular to a folding frame and bed, including two vertically distributed connecting frames. Each connecting frame includes a hinge and several legs spaced circumferentially around the hinge. One end of each leg is bent to form a bent foot, and the other end is hinged to the hinge. Two legs located in the same vertical direction are hinged together so that the folding frame can switch between an unfolded state and a folded state when the two hinges move linearly relative to each other. A limiting edge is formed on the hinge. When the folding frame is in the unfolded state, one end of each leg abuts against the corresponding limiting edge, so that the upper hinge and the hinged legs together form a planar unfolded shape or a near-planar shape with a central concave shape. This solves the problem that existing fixed bed frames cannot be folded and are inconvenient to use.

Description

Technical Field

[0001] This utility model relates to the field of pet bed technology, and in particular to a folding frame and bed. Background Technology

[0002] Pet beds, as the name suggests, provide a place for pets to rest. Common pet beds mainly consist of two parts: a bed frame and a bed surface. The bed frame supports the bed surface to form a bed. However, most existing bed frames use a fixed structure, which makes it impossible to fold and store pet beds, making them inconvenient to carry and transport, and thus have shortcomings. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a folding frame and bed, which solves the problem that existing fixed bed frames cannot be folded and are inconvenient to use.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a folding frame, comprising two vertically distributed connecting frames, each connecting frame including a hinge and a plurality of legs spaced circumferentially around the hinge. One end of each leg is bent to form a bent foot, and the other end is hinged to the hinge. Two legs located in the same vertical direction are hinged together so that the folding frame can switch between an unfolded state and a retracted state when the two hinges move linearly relative to each other. A limiting edge is formed on the hinge. When the folding frame is in the unfolded state, one end of each leg abuts against the corresponding limiting edge, so that the hinge at the upper end and the hinged legs together form a planar unfolded shape or a near-planar shape with a concave center.

[0005] Furthermore, the hinge has at least three legs.

[0006] By adopting the above technical solution, at least three legs are equidistantly distributed around the circumference, so that the load-bearing capacity is evenly transmitted to each leg. The tripod structure is stable under force and saves on the use of legs, effectively reducing costs.

[0007] Furthermore, a connecting groove is provided on the side of the hinge, and one end of the support leg is hinged in the connecting groove, with the bottom of the connecting groove forming a limiting edge.

[0008] By adopting the above technical solution, the support legs are directly embedded in the connecting groove for hinge connection, reducing additional fixing parts, production costs and assembly complexity.

[0009] Furthermore, the bending direction of the bent foot is the same as the opening direction of the connecting groove.

[0010] By adopting the above technical solution, the bending direction matches the connecting groove, and the legs and hinges fit more snugly after folding, reducing the space occupied.

[0011] Furthermore, the angle formed by the bent leg and the supporting leg is within 90 degrees to 165 degrees.

[0012] By adopting the above technical solution, the bending angle design, compared with the traditional linear setting of the legs, makes it easier for the upper hinge and the hinged legs to be in a near-planar state when the folding frame is unfolded, thus making it more stable after being fully unfolded.

[0013] Furthermore, the hinge points of the two vertically distributed legs are located at the bends near the legs.

[0014] By adopting the above technical solution, the hinge point is located close to the bending position, which can reduce stress concentration at the bending point and reduce the risk of structural damage.

[0015] A bed comprising the aforementioned folding frame, wherein the bed surface is detachably mounted on bent legs.

[0016] By adopting the above technical solutions, the removable bed surface design facilitates cleaning or replacement, improving hygiene.

[0017] Furthermore, the edge of the bed surface is provided with a sleeve, through which the bed surface is connected to the end of the bent leg.

[0018] By adopting the above technical solution, the connection between the sleeve and the bent foot end does not require tools, and users can easily install it themselves.

[0019] Furthermore, the bed also includes an assembly, where the bent legs of two adjacent folding frames are connected by the assembly, so that multiple beds can be assembled and unfolded in a planar manner.

[0020] By adopting the above technical solution and connecting multiple folding frames with assemblies, users can assemble them into larger pet beds to suit different numbers of pets or space requirements.

[0021] Furthermore, the bed is also equipped with a canopy, which includes a canopy surface and several canopy columns spaced around the perimeter of the canopy surface. One end of each canopy column is connected to the canopy surface, and the other end of each canopy column is connected in sequence to two vertically bent legs.

[0022] By adopting the above technical solution, the canopy columns and the bending feet are movably connected, allowing the height or angle of the canopy to be adjusted, thus avoiding the canopy columns affecting the folding or unfolding of the folding frame.

[0023] Compared with the prior art, the advantages of this utility model are:

[0024] In this invention, two connecting frames are vertically arranged, and the two legs are hinged together by hinges. In this way, the entire folding frame can be transformed into a folded / folded state during the linear push-pull process of the two hinges. After folding, it is convenient to transport and carry. Compared with the traditional fixed structure bed frame structure, this product is more convenient to use and carry.

[0025] In this invention, the design of a bent foot at one end of each support leg, combined with the limiting edge restricting the rotation angle of the support leg, allows the entire folding frame to form a planar unfolded shape or a slightly concave shape between the hinge at the upper end and the multiple hinged supports when it is in the unfolded state. In this shape, the line connecting the two hinges and the two vertically distributed supports form a right-angled triangle structure. Thus, when an external force is applied from the bent foot end of the support leg to close the folding frame, it cannot enter the folded state due to the limitation of the limiting edge and the right-angled triangle structure. This achieves the self-locking function of the folding frame when unfolded, effectively improving the support strength and stability of the entire folding frame after the bed surface is set.

[0037] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0038] Reference Figure 1 and 2 A folding frame includes two vertically distributed connecting frames 1. Each connecting frame 1 includes a hinge 12 and a plurality of legs 11 spaced apart around the hinge 12. One end of each leg 11 is bent to form a bent foot 111, and the other end is hinged to the hinge 12. Two legs 11 located in the same vertical direction are hinged to allow the folding frame to switch between an unfolded state and a folded state when the two hinges 12 move linearly relative to each other. A limiting edge 121 is formed on the hinge 12. When the folding frame is in the unfolded state, the end of each leg 11 connected to the hinge 12 rotates until it abuts against the limiting edge 121, reaching the maximum unfolding angle. At this time, the upper hinge 12 and the hinged legs 11 together form a planar unfolded shape or a near-planar shape with a concave center.

[0039] In this embodiment, two connecting frames 1 are vertically arranged, and after being hinged to the support legs 11 by hinge members 12, the two support legs 11 located in the vertical direction are hinged together. In this way, during the linear pushing and pulling process of the two hinge members 12, the entire folding frame can be in the unfolded state. Figure 3 ) and the collapsed state ( Figure 6 (As shown in the image) It can be folded for easy transport and carrying. Compared to traditional fixed bed frame structures, this product is more convenient to use and carry.

[0040] In this utility model, reference is made to Figure 1 The design of the bent foot 111 at one end of each support leg 11, combined with the restriction edge 121 restricting the rotation angle of the support leg 11, allows the entire folding frame to form a planar unfolded shape or a slightly concave shape between the hinge 12 at the upper end and the multiple hinged supports 11 when it is in the unfolded state. In this shape, the line connecting the two hinges 12 and the two vertically distributed supports 11 form a right-angled triangle structure. Thus, when an external force is applied from one end of the bent foot 111 of the support leg 11 to close the folding frame, it will be unable to enter the folded state due to the restriction edge 121 and the right-angled triangle structure formed, thereby realizing the self-locking function of the folding frame when unfolded, effectively improving the support strength and stability of the entire folding frame.

[0041] In this embodiment, the hinge member 12 is provided with a connecting groove 122 that forms a hinge with one end of the support leg 11. The end of the support leg 11 away from the bent foot 111 is rotatably disposed in the connecting groove 122 through a shaft, so that the support leg 11 can rotate relative to the hinge member 12 around the connecting groove 122.

[0042] In this embodiment, the connecting groove 122 is formed around the adjacent end faces of the two hinge members 12. The bottom of the connecting groove 122 forms the aforementioned limiting edge 121. The setting of the limiting edge 121 can limit the rotation angle of the support leg 11 around the hinge member 12. Thus, after the folding frame is fully unfolded, the limiting edge 121 can abut and limit the support leg 11. Another advantage is that by directly setting the connecting groove 122 on the hinge member 12 to accommodate one end of the support leg 11, it is also convenient to optimize the product structure of the hinge member 12, reduce the need for additional fixing components, and achieve the connection with the support leg 11.

[0043] In this embodiment, the shape of the hinge 12 can be a regular disc structure. As long as it is convenient to set the connecting groove 122 to form a hinge with the support leg 11, it can also be other shapes, which will not be described in detail here.

[0044] In this embodiment, the bending direction of the bent leg 111 is the same as the opening direction of the connecting groove 122. After folding, the leg 11 and the hinge 12 fit together more closely, reducing the space occupied.

[0045] In this embodiment, the angle between the bent leg 111 and the support leg 11 is within 90 degrees to 165 degrees. This bending angle design, compared with the traditional linear setting of the support leg 11, makes it easier for the hinge 12 at the upper end and the hinged support leg 11 to be in a near-plane state when the folding frame is unfolded. This ensures better stability of the product after unfolding and also effectively reduces the height of the product after unfolding, making it easier for pets to get on and off the bed.

[0046] In this embodiment, the hinge point of the two vertically distributed legs 11 is located near the bending position of the legs 11. The proximity of the hinge point to the bending position can reduce stress concentration at the bending point and reduce the risk of structural damage.

[0047] In this embodiment, a bed includes a bed surface 2, which is generally made of flexible materials such as nylon or rubber in the field of pet beds. The bed surface 2 is detachably installed on the bending legs 111 of the folding frame so as to facilitate the separation and carrying of the bed surface 2 from the folding frame.

[0048] In this embodiment, the supports 11 on the hinge 12 can be three, four, five, six, or more, and the bed surface 2 can be triangular, quadrilateral, hexagonal, circular, or other shapes. (Refer to...) Figure 4 Four legs 11 are hinged to one hinge member 12. After two hinge members 12 are hinged together through their respective legs 11, a quadrilateral folding frame is formed. The four corners of the bed surface 2 are provided with sleeves 21, and the four sleeves 21 are respectively installed on the bent legs 111 located at the upper end in the vertical direction.

[0049] In this embodiment, refer to Figure 3When each hinge 12 is provided with six legs 11, the corresponding bed surface 2 is hexagonal.

[0050] Based on the above embodiments, in order to further improve the practicality of the product, an assembly 3 can be set between the bending feet 111 between the two folding frames. The assembly 3 is similar in structure to the hinge 12. The assembly 3 is also provided with a connecting groove 122. By combining the connecting groove 122 with the bending feet 111, the splicing and combination of multiple folding frames can be realized, so as to achieve the purpose of freely adjusting the different areas of the bed surface 2.

[0051] Furthermore, refer to Figure 4 To enhance the comfort of the pet bed, a canopy 4 is provided. For ease of description, the upper hinge 12 of the two hinges 12 is referred to as the first hinge 12, and the support leg 11 and the bent leg 111 hinged on it are respectively referred to as the first support leg 11 and the first bent leg 111. The other hinge 12 is referred to as the second hinge, and the corresponding support leg 11 and the bent leg 111 are referred to as the second support leg 11 and the second bent leg 111. The canopy 4 includes a canopy surface 41 and several canopy columns 42 spaced around the canopy surface 41. The upper end of the canopy column 42 is connected to the canopy 4, and the lower end moves through the second bent leg 111 and is hinged to the first bent leg 111. In this way, by using the sliding connection between the canopy column 42 and the second bent leg 111, and the rotational connection between the lower end and the first bent leg 111, the presence of the canopy column 42 can be avoided from affecting the folding or unfolding of the folding frame.

[0052] Preferably, in this embodiment, a through hole 22 is provided on the bed surface 2 at the position corresponding to the canopy column 42, and then the canopy column 42 is directly inserted into the through hole 22 to realize the installation of the bed surface 2 and the folding frame. This eliminates the need to assemble the bed surface 2 with the second bending leg 111 and also eliminates the need to set the sleeve 21, effectively saving costs.

[0053] Although the preferred embodiments of the present invention have been described in detail above, it should be clearly understood that various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
