[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to and is based on Chinese Patent Application No. 2024208531031, filed with the China National Intellectual Property Administration on April 23, 2024, entitled "A Demountable Folding Bed Frame, Bedding and Sofa", the contents of which are incorporated herein by reference. Technical Field

[0003] This invention belongs to the field of furniture, specifically relating to a detachable folding bed frame, bedding, and sofa. Background Technology

[0004] Traditional bed frames are constructed by assembling multiple support panels, a headboard frame, and a bed board (or joists), with the support panels and headboard frame fixedly connected. This structure is bulky, and moving or retrieving the bed frame usually requires the cooperation of multiple people. With the increasing number of single-person households in contemporary society, fixed-connection bed frames are extremely inconvenient for these users.

[0005] Currently, various folding bed frames are available on the market, such as CN209331530U and CN214230639U. The main problem with these folding bed frames is that their primary technical solution is to use foldable bed boards or design the bed frame as a movable X-shaped support. While this design can reduce the storage space required after folding, it is still essentially a one-piece bed frame that cannot be easily disassembled, and it still cannot solve the inconvenience of moving the bed due to its large weight. Summary of the Invention

[0006] One of the objectives of this invention is to overcome the deficiencies of the prior art and provide a detachable folding bed frame and bedding and sofas including the folding bed frame.

[0007] Another object of the present invention is to provide another type of detachable folding bed frame.

[0008] The technical solution of the present invention is as follows:

[0009] A detachable folding bed frame, comprising a frame and longitudinal support beams;

[0010] The frame includes a headboard frame, a transverse support frame parallel to the headboard frame, and two opposing longitudinal support frames. The headboard frame, transverse support frame, and longitudinal support frame can be folded in half. The transverse support frame and the headboard frame are positioned opposite each other, and the two ends of the longitudinal support frame are respectively engaged with the headboard frame and the transverse support frame.

[0011] Multiple longitudinal support beams are arranged in parallel, and each longitudinal support beam is detachably connected to the transverse support frame and the headboard frame.

[0012] In some possible implementations, the longitudinal support beam includes two support rods and a support leg. One end of the support leg is connected to a pivot groove perpendicular to the support leg. The two ends of the pivot groove are pivotally connected to a support rod. When the longitudinal support beam is folded, the support rods and the support leg are parallel. When the longitudinal support beam is opened, the two support rods are perpendicular to the support leg, and the end of the support rod that is hinged to the pivot groove abuts against the bottom of the pivot groove.

[0013] The two support rods of the longitudinal support beam have their connecting ends at the ends furthest from the pivot groove. The two connecting ends of the longitudinal support beam are respectively snapped or hooked to the transverse support frame and the headboard frame.

[0014] In some possible implementations, the folding bed frame also includes transverse support beams perpendicular to the longitudinal support beams;

[0015] The two ends of the transverse support beam can be detachably connected to the two longitudinal support beams, or one end of the transverse support beam can be detachably connected to the longitudinal support beam and the other end can be detachably connected to the frame.

[0016] More preferably, the longitudinal support beam has a plurality of first slots in the length direction of the first support rod. Each first slot has two slots arranged side by side in the length direction perpendicular to the first support rod, and each first slot can engage with one end of two transverse support beams.

[0017] More preferably, multiple transverse support beams are arranged in two rows along the length of the folding bed frame, and each transverse support beam is connected at both ends to a longitudinal support frame and a longitudinal support beam, respectively.

[0018] In some possible implementations, each longitudinal support beam is snapped or hooked to the transverse support frame and the headboard frame, respectively.

[0019] In some possible implementations, the frame also includes legs, which are set on the bottom surfaces of the transverse support frame, the longitudinal support frame, and the headboard frame.

[0020] In some possible implementations, the folding bed frame also includes a bed frame upholstery covering the surfaces of the folding bed frame excluding the headboard frame and the bottom surface of the folding bed frame.

[0021] A type of bedding, including the aforementioned folding bed frame.

[0022] A sofa that includes the aforementioned folding bed frame.

[0023] This invention also provides another detachable folding bed frame, the frame of which is formed by two opposing longitudinal support frames, a headboard frame, and a transverse support frame that can be detachably snapped together. The longitudinal support beam is then snapped onto the transverse support frame, and the transverse support beam is snapped onto the longitudinal support frame and / or the longitudinal support beam. All components of the folding bed frame are detachable, facilitating individual transport by the user. Attached Figure Description

Detailed Implementation

[0047] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the familiar embodiments are merely one implementation of the present invention. All other embodiments obtained by those skilled in the art based on the following embodiments without creative effort are within the protection scope of the present invention.

[0048] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intervening element. In this invention, the terms "upper," "lower," "bottom," "rear," "side," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the purpose of simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. In this embodiment, "lower" refers to the direction near the ground or other supporting surface after the elements are unfolded and assembled to form a folding bed frame. "Inner surface" refers to the side of the folding bed frame near the center of the folding bed frame after the elements are assembled. In this application, "lateral" refers to the direction along the width of the folding bed frame, and "longitudinal" refers to the direction along the length of the folding bed frame. However, here "lateral" and "longitudinal" or "width direction" and "length direction" are only two mutually perpendicular directions and do not impose other restrictions on the folding bed frame. For example, the dimension of the folding bed frame along its length direction can be greater than, equal to or smaller than its dimension in the width direction.

[0049] A detachable folding bed frame includes a frame 1, a longitudinal support beam 2, and a transverse support beam 3 arranged perpendicular to the longitudinal support beam 2.

[0050] The frame 1 includes a headboard frame 11, a transverse support frame 13 parallel to the headboard frame 11, and two opposing longitudinal support frames 12, as shown in Figures 1-6. The headboard frame 11, the transverse support frame 13, and the longitudinal support frames 12 can be folded. As shown in Figure 10, the transverse support frame 13 and the headboard frame 11 are opposite each other, and the two ends of the longitudinal support frames 12 are detachably connected to the headboard frame 11 and the transverse support frame 13, respectively. In this embodiment, the detachable connection is achieved by engaging the connecting protrusion 14 and the connecting hole 121.

[0051] The bottom surface of frame 1 has multiple legs 16, which reduce the contact area between the folding bed frame and the ground, thus preventing dust accumulation. In this embodiment, the headboard frame 11 has a built-in metal bracket, and the transverse support frame 13 and the longitudinal support frame 12 are also metal frames.

[0052] Specifically, connecting protrusions 14 (not shown in Figures 1-2; for the connecting protrusions 14 of the headboard frame 11, please refer to Figures 7-10) are provided at both ends of the inner surface of the headboard frame 11 and the transverse support frame 13. Connecting holes 121 are provided at both ends of the longitudinal support frame 12 along its length direction, as shown in Figures 7-10. After the headboard frame 11, the longitudinal support frame 12, and the transverse support frame 13 are unfolded, they are snapped together by the cooperation of the connecting protrusions 14 and the connecting holes 121. For example, the two longitudinal support frames 12 can be snapped together with the headboard frame 11 first, and then the transverse support frame 13 can be snapped together with the end of the longitudinal support frame 12 that is not snapped together with the headboard frame 11.

[0053] As shown in Figure 15, multiple longitudinal support beams 2 are arranged side by side. Each longitudinal support beam 2 is detachably snapped or hooked to the transverse support frame 13 and the headboard frame 11. Each longitudinal support beam 2 includes two support rods 21 and support legs 22. One end of each support leg 22 is connected to a pivot groove 23 perpendicular to the support leg 22. Both ends of the pivot groove 23 are pivotally connected to a support rod 21. When the longitudinal support beam 2 is folded, the support rods 21 and support legs 22 are parallel. When the longitudinal support beam 2 is unfolded, the ends of the two support rods 21 perpendicular to the support legs 22 and hinged to the pivot groove 23 abut against the bottom of the groove. The ends of the two support rods 21 of the longitudinal support beam 2 furthest from the pivot groove 23 are connecting ends 211. The longitudinal support beam 2 is snapped or hooked to the transverse support frame 13 and the headboard frame 11 through the connecting ends 211. One of the longitudinal support beams 2 is roughly located on the axis of symmetry along the length of the folding bed frame. The longitudinal support beam 2 has multiple first slots 24 along its length, which can engage with two transverse support beams 3.

[0054] This embodiment designs two types of connection ends 211. Referring first to Figures 11 and 12, the connection end 211 forms a hook 212, which is hooked onto the metal brackets of the transverse support frame 13 and the headboard frame 11 (see Figures 15, 17, and 18). Its specific structure is shown in Figures 13 and 14. The connection end 211 of the longitudinal support beam 2 forms a snap-fit ​​groove 213, and the inner wall of the snap-fit ​​groove 213 is provided with snap-fit ​​protrusions 214. The headboard frame 11 and the transverse support frame 13 are engaged with the snap-fit ​​sub-parts 15 and snap-fit ​​grooves 213 as shown in Figures 10 and 16. The snap-fit ​​sub-parts 15 are roughly strip-shaped in the vertical direction. Snap-fit ​​holes 151 are provided at the corresponding positions of the snap-fit ​​sub-parts 15 and the snap-fit ​​protrusions 214. The snap-fit ​​grooves 213 first contact the snap-fit ​​sub-parts 15, and then slide until the snap-fit ​​protrusions 214 enter the snap-fit ​​holes 151, thus achieving the engagement of the headboard frame 11 and the transverse support frame 13 with the longitudinal support beam 2.

[0055] Figure 19 is a schematic diagram of the transverse support beam 3. The transverse support beam 3 has downward-facing inserts 31 at both ends. The top surface of the longitudinal support frame 12 has multiple second slots 122 along its length (see Figures 3 and 4). Each second slot 122 can be inserted into one insert 31. The two ends of the transverse support beam 3 are respectively inserted into a second slot 122 and a first slot 24 via inserts 31, completing the installation of the transverse support beam 3 and resulting in the folding bed frame shown in Figure 20.

[0056] Furthermore, in this embodiment, the folding bed frame also includes a bed frame upholstery 4, as shown in Figures 21 and 22, which covers all surfaces of the folding mattress except for the bottom and headboard frame 11.
