Detailed Description

Complete technical specification and implementation details from the patent document.

This application claims priority to Chinese patent application number 202420853103.1, filed on Apr. 23, 2024. Chinese patent application number 202420853103.1 is incorporated herein by reference.

The present disclosure relates to the field of furniture, and in particular to a detachable folding bed frame, a bed, and a sofa.

Traditional bed frames are assembled from a plurality of support panels, a headboard frame, and bed slats (or stringers), with fixed connections between the plurality of support panels and the headboard frame. Such structures are bulky, requiring collaboration among multiple people for transportation or recycling. In modern society, the number of single-person households is gradually increasing, making fixed-connection bed frames highly inconvenient for such users.

Currently, various foldable bed frames exist on the market, such as those disclosed in CN209331530U and CN214230639U. The primary issue with these designs lies in their technical approach; these designs either utilize foldable bed boards or employ movable X-shaped supports. While such designs reduce the storage space required after folding, these designs remain integrated structures that cannot be easily disassembled. Consequently, the inconvenience of transportation due to the substantial weight of the bed frame persists.

The technical problem to be solved by the present disclosure is to provide a detachable folding bed frame, a bed, and a sofa, and the bed and the sofa each comprises the detachable folding bed frame.

In order to solve the above technical problems, the present disclosure provides a detachable folding bed frame, a bed, and a sofa.

A detachable folding bed frame comprises a frame and a plurality of longitudinal supporting beams.

The frame comprises a headboard frame, a transverse supporting frame parallel to the headboard frame, and two longitudinal supporting frames arranged opposite to each other. The headboard frame, the transverse supporting frame, and the two longitudinal supporting frames are configured to be foldable. The transverse supporting frame and the headboard frame are arranged opposite to each other, and two ends of each of the two longitudinal supporting frames are respectively buckled to the headboard frame and the transverse supporting frame.

The plurality of longitudinal supporting beams are arranged in parallel to each other, and each of the plurality of longitudinal supporting beams is detachably connected to the transverse supporting frame and the headboard frame.

In some possible implementations, each of the plurality of longitudinal supporting beams comprises two supporting rods and a supporting leg. A first end of the supporting leg comprises a pivoting groove perpendicular to the supporting leg, and two ends of the pivoting groove are respectively pivotally connected to the two supporting rods. When each of the plurality of longitudinal supporting beams is folded, the two supporting rods and the supporting leg are parallel to each other. When each of the plurality of longitudinal supporting beams is unfolded, the two supporting rods are perpendicular to the supporting leg, and a first end of each of the two supporting rods pivotally connected to the pivoting groove abuts a bottom of the pivoting groove.

Second ends of each of the two supporting rods of each of the plurality of longitudinal supporting beams away from the pivoting groove are two connecting ends, and the two connecting ends of each of the plurality of longitudinal supporting beams are buckled or hooked to the transverse supporting frame and the headboard frame.

In some possible implementations, the detachable folding bed frame comprises one or more transverse supporting beams, and the one or more transverse supporting beams are configured to be arranged perpendicular to the plurality of longitudinal supporting beams.

The technical solutions of the present disclosure will be described clearly and comprehensively below in conjunction with the accompanying drawings. It should be noted that the described embodiments represent merely one implementation of the present disclosure. All other embodiments obtained by those skilled in the art based on the following examples without creative efforts shall fall within the protection scope of the present disclosure.

It is hereby clarified that when a component is described as being “fixed to” another component, it may be directly attached to that component or may have intervening elements in between. When a component is considered “connected” to another component, it may be directly linked or may have intermediary components. In this application, directional terms such as “upper,” “lower,” “bottom,” “rear,” and “side” refer to orientations or positional relationships based on the accompanying drawings. These terms are used solely to simplify description and do not imply that the described device or component must adopt a specific orientation or configuration. Therefore, such terms should not be construed as limitations on the present disclosure. In this embodiment, “lower” refers to the direction toward ground or a supporting surface when the components are unfolded and assembled into a detachable folding bed frame. “Inner surface” denotes a side of the components that faces a middle of the assembled bed frame. The term “transverse” herein refers to a width direction of the detachable folding bed frame, while “longitudinal” refers to a length direction. However, “transverse” and “longitudinal” (or “width direction” and “length direction”) are merely two mutually perpendicular orientations and impose no additional constraints on the bed frame. For example, the dimension along a length of detachable folding bed frame may be greater than, equal to, or less than a width dimension of the detachable folding bed frame.

A detachable folding bed frame comprises a frame, a plurality of longitudinal supporting beams, and one or more transverse supporting beamsconfigured to be arranged perpendicular to the plurality of longitudinal supporting beams.

The framecomprises a headboard frame, a transverse supporting frameparallel to the headboard frame, and two longitudinal supporting framesarranged opposite to each other. As shown in, each of the headboard frame, the transverse supporting frame, and the two longitudinal supporting framesis configured to be folded. As shown in, the transverse supporting frameand the headboard frameare arranged opposite to each other, and two ends of each of the two longitudinal supporting framesare respectively and detachably connected to the headboard frameand the transverse supporting frame. In this embodiment, the detachable connection is achieved by a buckling connection of one or more connecting protrusionsand one or more connecting holes.

A bottom surface of the frameis formed with a plurality of legs, and the plurality of legscan reduce a contact area between the detachable folding bed frame and ground to have a function of dust prevention. In this embodiment, the headboard frameis built with a metal bracket, and the transverse supporting frameand the two longitudinal support framesare metal frames.

Specifically, two ends of an inner surface of the headboard frameand two ends of an inner surface of the transverse supporting frameeach comprises the one or more connecting protrusions(not shown in, please refer tofor the one or more connecting protrusionsof the headboard frame), and the two ends of each of the two longitudinal supporting framesalong a length direction of the two longitudinal supporting framescorrespondingly comprises the one or more connecting holes. As shown in, after the headboard frame, the two longitudinal supporting frames, and the transverse supporting frameare unfolded, the headboard frame, the two longitudinal supporting frames, and the transverse supporting frameare configured to be connected by cooperation of the one or more connecting protrusionsand the one or more connecting holes. For example, the two longitudinal supporting framescan be connected to the headboard frame, and then the transverse supporting framecan be connected to the two ends of each of the two longitudinal supporting framesthat are not connected to the headboard frame.

As shown in, the plurality of longitudinal supporting beamsare arranged in parallel to each other, and each of the plurality of longitudinal supporting beamsis detachably buckled or hooked to the transverse supporting frameand the headboard frame. Each of the plurality of longitudinal supporting beamscomprises two supporting rodsand a supporting leg. A first end of the supporting legcomprises a pivoting grooveperpendicular to the supporting leg. Two ends of the pivoting grooveare respectively pivotally connected to the two supporting rods. When each of the plurality of longitudinal supporting beamsis folded, the two supporting rodsand the supporting legare parallel to each other. When each of the plurality of longitudinal supporting beamsis unfolded, the two supporting rodsare perpendicular to the supporting leg, and a first end of each of the two supporting rodspivotally connected to the pivoting grooveabuts a bottom of the pivoting groove. A second end of each of the two supporting rodsof each of the plurality of longitudinal supporting beamsaway from the pivoting grooveis a connecting end. Each of the plurality of longitudinal supporting beamsis buckled or hooked to the transverse supporting frameand the headboard framethrough the connecting ends. One of the plurality of longitudinal supporting beamsis substantially arranged on a symmetry axis along a length direction of the detachable folding bed frame. Each of the plurality of longitudinal supporting beamscomprises a plurality of first buckling groovesalong a length direction of the plurality of longitudinal supporting beams. The plurality of first buckling groovescan be connected to the one or more transverse supporting beams.

This embodiment provides two embodiments of the connecting end. In a first embodiment of the connecting end, referring to, the connecting endis configured as a hook, and the hooksof the two supporting rodsare hooked on the metal bracket of the headboard frameand the transverse supporting frame(see). A second embodiment of the connecting endis shown in. The connecting endis configured as a buckling groove, and an inner wall of the buckling grooveis disposed with one or more buckling protrusions. Each of the headboard frameand the transverse supporting frameis buckled to a corresponding one of the two supporting rodsthrough a buckling sub-componentas shown inand the buckling groove. The buckling sub-componentis substantially strip-shaped in a vertical direction. The buckling sub-componentcomprises one or more buckling holesconfigured to correspond to the one or more buckling protrusions. The buckling groovefirst abuts the buckling sub-component, and then the buckling grooveslides until the one or more buckling protrusionsenter the one or more buckling holes, thereby achieving engagement of the headboard frameand the transverse supporting framewith the plurality of longitudinal supporting beams.

is a structural schematic diagram of the one or more transverse supporting beams. Two ends of each of the one or more transverse supporting beamsare disposed with insertion sheetsextending downward. A top surface of each of the two longitudinal support framescomprises a plurality of second buckling grooves(seeand) along the length direction of the two longitudinal supporting frames. Each of the plurality of second buckling groovescan be plugged with a corresponding one of the insertion sheets. The two ends of each of the one or more transverse supporting beamsare respectively inserted into a corresponding one of the plurality of second buckling groovesand a corresponding one of the plurality of first buckling groovesthrough the insertion sheets, and an installation of the one or more transverse supporting beamsis completed to form the detachable folding bed frame shown in.

Furthermore, in this embodiment, the detachable folding bed frame further comprises a bed frame upholstery, as shown in, and the bed frame upholsterycovers all surfaces of the detachable folding bed frame except a bottom surface and the headboard frame.

The aforementioned embodiments are merely some embodiments of the present disclosure, and the scope of the disclosure is not limited thereto. Thus, it is intended that the present disclosure cover any modifications and variations of the presently presented embodiments provided they are made without departing from the appended claims and the specification of the present disclosure.
