Description

Technical Field

[0001] The utility model relates to a household item, in particular to a folding bed which is convenient for storage. Background Art

[0002] A folding bed is a simple bed that divides the bed board into multiple segments and directly hinges the segments, which can facilitate and save volume space, and can be folded and retracted through various folding methods. The existing folding beds generally have insufficient support. Since the folding bed needs to be folded, the folding structure is prone to dents or deformation under weight, and it is difficult to maintain a relatively stable flat state. The folding structure of the folding bed is prone to large forces at the folding and other positions, which is likely to cause damage to the hinged part. Moreover, due to its frequent folding and unfolding, the wear between components will be faster, resulting in a relatively short service life. Therefore, the support of the existing folding bed is inferior to that of traditional beds, and long-term use may have a certain impact on the spine. At the same time, the durability of the folding bed may be lower than that of traditional beds. And the existing folding beds mainly achieve folding through a simple hinged structure. For folding beds using this kind of structure, generally no relatively high headrest is set at both ends of the bed body. If a headrest is set, the headrest will protrude outwards after being stored, which generally affects the storage of the folding bed. Therefore, the existing folding beds generally cannot rely on and limit the position at the head part. Summary of the Invention

[0003] The purpose of the utility model is to provide a folding bed which is convenient for storage in view of the deficiencies of the prior art. It has a simple and compact structure, can bear weight reliably, is easy to fold and retract, and has a small volume after folding, which is convenient for storage and transportation.

[0004] The purpose of the utility model is realized as follows: A folding bed which is convenient for storage includes a bed board frame arranged horizontally. The adjacent ends of the bed board frame are hinged to each other through a group of connecting pieces. Among them, the connecting piece includes a first upright post. A supporting seat is arranged at the top end of the first upright post. The supporting seat is provided with a supporting surface. A limiting piece protruding from the supporting surface is arranged on the supporting seat. The limiting piece has a limiting surface for abutting against the outer side walls of the two bed board frames. The two ends of the limiting piece respectively protrude out of the supporting surface and are hinged to the side walls of the bed board frame. A headrest is arranged corresponding to the distal end of the bed board frame. The headrest has two second upright posts extending downwards. The outer side of each second upright post of the headrest is hinged to the first end of a corresponding first connecting rod. The second end of the first connecting rod is hinged to the outer side wall of the adjacent bed board frame. The inner side of each second upright post of the headrest is hinged to the first end of a corresponding second connecting rod. The second end of the second connecting rod is hinged to the inner side wall of the bed board frame. At least one of the second upright posts of the headrest is detachably connected to the first end of a third connecting rod. The second end of the third connecting rod is hinged to the side wall of the adjacent bed board frame.

[0005] The headstock includes a U-shaped frame which is integrally formed. The vertical projection of the headstock and the vertical projection of the bed board frame are arranged horizontally. Two second columns are respectively formed on both side walls of the U-shaped frame, and the lower sections of the two second columns are connected by a horizontal reinforcing bar.

[0006] Hanging pins and third connecting rods are respectively connected to both side walls of each bed board frame. The hanging pin on one bed board frame and the third connecting rod on the other bed board frame are on the same side. A mounting notch is provided at the second end of the third connecting rod, and a pin adapted for mounting with the mounting notch is provided on the second column of the headstock corresponding to the third connecting rod.

[0007] The mounting notch is arranged downward and has a structure with a small mouth and a large bottom.

[0008] The first connecting rod, the second connecting rod, and the third connecting rod are all in sheet form, and the second connecting rod is parallel to the third connecting rod or the intersection point of the second connecting rod and the third connecting rod is outside the second connecting rod.

[0009] The first column is eccentrically arranged and rotatably supported below the support seat. The center line of rotation of the first column is parallel to the axis of the first column.

[0010] The first column is provided with a radially extending lug. The lower end of the support seat is eccentrically provided with a connecting bolt. The lug is threadedly connected to the connecting bolt through a threaded hole. The lower end of the support seat is provided with an abutting surface for abutting against the upper end surface of the first column.

[0011] Adopting the above-mentioned utility model, the beneficial effects are as follows: The horizontally arranged bed board frames can be opened and folded in a hinged form. When the two bed board frames are folded, the connecting piece can not only be connected to the horizontally arranged bed board frames to form a flat bed structure. The supporting surface can support the bed board frames in the opened state. When a large force is applied in the middle of the bed body, a reliable upward support is formed to avoid the depression in the middle of the bed body. The bed board frames can be restricted in the width direction through the limiting surface to avoid the phenomenon of misalignment and jamming in the opened and folded states. Both ends of the limiting piece respectively extend out of the supporting surface and are hinged to the side wall of the bed board frame. Through the extending structure, interference with the support seat during the folding process can be avoided, facilitating the opening and folding of the folding bed. Through the third connecting rod, the four-bar linkage structure formed by the first connecting rod, the second connecting rod, the bed board frame, and the headstock can be locked, preventing deformation during use or under load. When folding is required, the third connecting rod is disassembled from the second column, and the four-bar linkage structure formed by the first connecting rod, the second connecting rod, the bed board frame, and the headstock can be deformed to achieve folding. When storing, the headstock is received under the bottom of the bed board frame, avoiding the occupation of the space outside the bed board frame. After folding, the two bed board frames, the headstock, and the first column are stacked in the height direction of the bed board frame, and the folded volume is compact, facilitating storage and transportation.

[0012] Adopting the present utility model, the structure is simple and compact. When in the open state, it can bear weight reliably, is easy to fold, and when in the folded state, it has a small volume and a stable folded state, which is convenient for storage and transportation.

Detailed Embodiment

[0018] Referring to the accompanying drawings, the specific implementation scheme of the present utility model will be described in detail.

[0019] See Figures 1 to 3 , an embodiment of a folding bed that is convenient for storage. A folding bed that is convenient for storage includes a horizontally arranged bed board frame 100. The bed board frame 100 can be made of metal. A plurality of supporting strips can be arranged in the bed board frame 100, and gaps can be left between the supporting strips. The adjacent ends of the bed board frame 100 are hinged to each other through a group of connecting members 200, and folding in half can be achieved through the hinged form, which is convenient for storage.

[0020] Specifically, the connecting member 200 includes a first upright post 210. A support seat 220 is provided at the top end of the first upright post 210. The support seat 220 is provided with a support surface 221. A limiting member 230 protruding from the support surface 221 is provided on the support seat 220. The limiting member 230 has a limiting surface 213 for abutting against the outer side walls of the two bed frame frames 100. Both ends of the limiting member 230 respectively protrude out of the support surface 221 and are hinged to the side walls of the bed frame frame 100. A headrest frame 300 is provided corresponding to the distal end of the bed frame frame 100. The headrest frame 300 has two second upright posts 310 extending downward. The outer side of each second upright post 310 of the headrest frame 300 is hinged to the first end of a corresponding first connecting rod 320. The second end of the first connecting rod 320 is hinged to the outer side wall of the adjacent bed frame frame 100. The inner side of each second upright post 310 of the headrest frame 300 is hinged to the first end of a corresponding second connecting rod 330. The second end of the second connecting rod 330 is hinged to the inner side wall of the bed frame frame 100. At least one of the second upright posts 310 of the headrest frame 300 is detachably connected to the first end of a third connecting rod 400. The second end of the third connecting rod 400 is hinged to the side wall of the adjacent bed frame frame 100.

[0021] In some embodiments, the headrest frame 300 includes a U-shaped frame which is integrally formed. The vertical projection of the headrest frame 300 and the vertical projection of the bed frame frame 100 are arranged horizontally. The two side walls of the U-shaped frame respectively form two second upright posts 310. The lower segments of the two second upright posts 310 are connected by a transverse reinforcing rod. With this structure, in the open state, the upper segment of the headrest frame 300 can protrude above the plane where the bed frame frame 100 is located, which can facilitate a person to lean against or limit in the length direction of the bed body. At the same time, when in the storage state, it is convenient for the headrest frame 300 to be folded at the bottom of the bed frame frame 100. Among them, the upper segment of the headrest frame 300 can also be stored at the bottom of the bed frame frame 100, which can both form a limit on both sides formed by the bed frame frame 100 and have a relatively small overall length when being stored.

[0022] In some embodiments, hanging pins 101 and third connecting rods 400 are respectively connected to both side walls of each bed board frame 100. The hanging pin 101 on one bed board frame 100 and the third connecting rod 400 on the other bed board frame 100 are located on the same side. A mounting notch is provided at the second end of the third connecting rod 400, and a pin adapted for mounting with the mounting notch is provided on the second upright column 310 of the headstock 300 corresponding to the third connecting rod 400. With this structure, when the bed board frame 100 is in the open state, the third connecting rod 400 is hooked on the hanging pin 101 through the mounting notch, which can lock the four-bar linkage structure formed by the first connecting rod 200, the second connecting rod 200, the bed board frame 100, and the headstock 300, and can prevent deformation during use or under load. Of course, when storage is required, the third connecting rod 400 is disengaged from the hanging pin 101, so that the formed four-bar linkage structure can be deformed, and then the headstock 300 can be folded to the bottom of the bed board frame 100. With the cooperation structure of the hanging pin 101 and the mounting notch, no tool assistance is required during each use process, which is convenient and easy to operate. Further, the mounting notch is arranged downward, and the mounting notch has a structure with a small mouth and a large bottom. With this structure, when the mounting notch is mounted with the hanging pin 101, even if there is a play situation, it is not easy to fall off the hanging pin 101. At the same time, with this structure, when storing, the third connecting rod 400 can be mounted with the hanging pin 101 on another bed board frame 100, which can lock the folding bed in the locked state and prevent the folding state from being unstable.

[0023] In some embodiments, the first connecting rod 320, the second connecting rod 330, and the third connecting rod 400 are all in a sheet shape. The sheet structure can reduce the thickness. Among them, the second connecting rod 330 is parallel to the third connecting rod 400 or the intersection point of the second connecting rod 330 and the third connecting rod 400 is located outside the second connecting rod 330. With this setting, it can prevent the second connecting rod 330 and the third connecting rod 400 from crossing, avoid friction during movement, and at the same time avoid having a large thickness in the thickness direction of the connecting rod.

[0024] In some embodiments, to make the folded folding bed have a smaller thickness and at the same time the headstock 300 can have a longer height of the lower end; the first upright column 210 is eccentrically arranged and rotatably supported below the support seat 220, and the rotation center line of the first upright column 210 is parallel to the axis of the first upright column 210. With this structure, when the first upright column 210 is folded, its eccentric state can be adjusted by rotation, and the second upright column 310 of the headstock 300 can be staggered from the first upright column 210 after folding. Therefore, the two bed board frames 100 can have a smaller folding thickness, and the hinged position between them can be set closer.

[0025] Furthermore, the first upright column 210 is provided with a radially extending lug 211, the lower end of the support seat 220 is eccentrically provided with a connecting bolt 232, the lug 211 is threadedly connected to the connecting bolt 232 through a threaded hole, and the lower end of the support seat 220 is provided with an abutting surface for abutting against the upper end surface of the first upright column 210. With this structure, eccentric rotation of the first upright column 210 can be achieved through screw matching, and it can be staggered with the second upright column 310 in position. The hinge positions of the two bed frame frames 100 on the connecting member 200 can be set shorter, that is, the distance between the adjacent bed frame brackets 100 can be smaller.

[0026] At the same time, when the second upright column 310 rotates, it can move in the vertical direction. Thus, at the corresponding position of the abutting surface, continuous rotation can squeeze the abutting surface, enabling the second upright column 310 to be tightly abutted against the abutting surface, preventing the play of the first upright column 210 caused by the play of the folding bed.

[0027] With the above-mentioned utility model, when it needs to be opened, first loosen the hanging pin 101 of the third connecting rod 400 in the folded state, and the four-link structure formed by the first connecting rod 200, the second connecting rod 200, the bed frame 100, and the headrest 300 can be unfolded, enabling the headrest 300 to extend and be locked. When it needs to be folded, disassemble the third connecting rod 400 from the second upright column 310, and the four-link structure formed by the first connecting rod 200, the second connecting rod 200, the bed frame 100, and the headrest 300 can be deformed to achieve folding. When folding, the headrest 300 is received at the bottom of the bed frame 100, avoiding the occupation of the space outside the bed frame 100. After folding, the two bed frames 100, the headrest 300, and the first upright column 210 are stacked in the height direction of the bed frame 100, and the folded volume is compact, facilitating storage and transportation.

[0028] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and its equivalent technologies, the present utility model also intends to include these changes and modifications.
