Abstract
Description
Attaching Sturdy Bed Joists Technical Field
[0001] The present invention relates to a piece of furniture, and more particularly to a bed joist with a firmly connected bed. Background Art
[0002] Dormitory beds, student apartment beds, and other beds with metal bed edges connected to a stable bed joist structure utilize welding processes, which are relatively simple and convenient to manufacture. However, transporting, storing, and relocating beds are relatively cumbersome and inconvenient. With the continuous advancement of technology, existing component-assembled beds have seen a wide variety of product structures, and the shape, structure, and installation and connection techniques of the tubular components have also improved. However, their effectiveness remains to be seen. For example, the composition and connection structure of components such as the bed edge and the stable bed joist itself have not yet been fully satisfactory. In particular, due to inadequate composition and connection structures, the requirements for firmness, strength, and durability conflict with the manufacturing process, installation, assembly, and connection methods, resulting in poor economic efficiency and certain safety aspects that need improvement. Furthermore, the stable bed joist and bed joist, when used, can produce pulsating impact noise due to stress.
[0003] Summary of the Invention
[0004] The purpose of the present invention is to address the problems existing in the prior art and provide a bed slat joist with a stable connection. The bed slat joist with a stable connection has a simple and reasonable structure and high relative mechanical strength.
[0005] The technical solution of the present invention for connecting a stable bed board support beam includes a support beam body, the support beam body includes an open frame body, the open frame body includes an open frame edge on one side, a frame edge on the side opposite to the open frame edge, and frame edges on both sides adjacent to the open frame edge, the open frame body is provided with an adaptive tensioning connection device, the adaptive tensioning connection device includes an adaptive expansion opening opened on the open frame edge, and corresponding tensioning devices provided at the opposite ends of the support beam body.
[0006] The joist body is made of a plate which is pressed and bent by a corresponding processing device.
[0007] The present invention has an extremely simple and reasonable connection structure composed of firmly connected bed board support beams. The connection structure is particularly stable and reliable, the connection mechanical strength is particularly high, and the assembly process is particularly simple and convenient. The bed components themselves have high compressive and bending strengths, making the entire bed structure stable, firm, strong, and durable. On the basis of ensuring strength and reliability, it can relatively save on raw materials used in manufacturing, correspondingly reducing production and use costs, and has good safety in use. The special structural setting of the pressure-bearing buffer device can eliminate noise during use of the bed board, and at the same time, the assembly connection performance of the firmly connected bed board support beams and the bed edge can be optimized.

[0010] In order to facilitate a better understanding of the technical solution of the present invention, the present invention is further clearly and completely described below through embodiments in conjunction with the accompanying drawings.
[0011] It should be noted that the up, down, left, and right described in the present invention are all relative to the drawings, which are intended to facilitate the description of the corresponding technical features and do not constitute a limitation on the corresponding technical features of the present invention; the relevant dimensions and angle values are only relative to the corresponding embodiments and do not constitute any limitation or limitation on the structural principle and technical solution of the present invention.
[0012] As shown in Figures 1-7, in Example 1, the present invention's securely connected bed joist, i.e., the joist body, includes an open frame and an adaptive tensioning connection device disposed within the open frame. The adaptive tensioning connection device includes an adaptive expansion opening 6, a tensioning device, a position-limiting buckle device, and a locking connection device.
[0013] The open frame 1 includes the support beam body or one open frame side in its cross-sectional direction, a frame side opposite to the open frame side, two adjacent frame sides or left and right frame sides 7 of the open frame side, and another two opposite frame sides or upper and lower frame sides.
[0014] In this embodiment, the open frame side corresponds to the upper frame side 9, the opposite frame side corresponds to the lower frame side 8, and the adjacent two frame sides correspond to the left and right frame sides 7. Corresponding bed boards are arranged on the open frame sides.
[0015] The left and right frame edges 7 of the open frame 1 are inclined downward from the upper frame edge 9 toward each other, i.e., inwardly, to form inclined frame edges. The opposite ends of the left and right frame edges 7 are located adjacent to the upper frame edge 9 to form tensioning edges 7a. The center portions of the left and right frame edges 7 are each provided with a recessed portion 4 that is recessed toward each other, i.e., inwardly.
[0016] The upper side frame edge 9 of the open frame is divided into left and right frame edges 9a by an adaptive expansion opening 6 extending along the length of the joist body. One side of the left frame edge 9a is connected to the corresponding side of the left frame edge 7, and one side of the right frame edge 9a is connected to the corresponding side of the right frame edge. The open frame edge, the opposing frame edges, and the adjacent two frame edges are interconnected to form the joist body with an open frame structure on one side. The left and right frame edges 9a of the upper side frame edge 9 are each provided with a recessed portion 4.
[0017] The adaptive expansion opening 6 may be located in the middle of the upper frame edge 9 , and the joist body may be symmetrical in its length direction about the midline of the adaptive expansion opening 6 in the length direction.
[0018] The left and right frame edges 7 are respectively provided with locking slots 3 on one side close to the upper frame edge 9. The locking slots 3 correspond to the corresponding connection parts of the bed edge, forming corresponding locking connection devices.
[0019] The recessed portions 4 of the left and right side frames 7 and the upper side frame 9 are formed by pressing the corresponding portions of the frame edges inward toward the inside of the joist body. The recessed portions 4 are flat-bottomed recessed portions. The width of the upper side recessed portion can be 1 / 3-1 / 4 of the width of the left and right side frame bodies 9a of the upper side frame 9, respectively. The width of the recessed portions of the left and right side frames 7 is approximately 1 / 3 of the width of the left and right side frames.
[0020] The left and right frame side bodies 9a of the upper frame side 9 are provided with convex edges 5 on the facing side walls respectively. The convex edges and the upper frame side may form an angle of 90 degrees.
[0021] The lower frame edge 8 is designed to resemble a U-shaped bottom edge, forming the bottom portion of a U-shape. The two sides of the U-shaped lower frame edge 8 are connected to the left and right side frames. Near opposite ends of the lower frame edge 8, a snap-fit slot 2 is provided, oriented transversely to the joist body. The center of each snap-fit slot 2 is provided with a machined assembly hole. The R of the curved angles on either side of the lower frame edge 8 is approximately 22 mm. The snap-fit slots 2 are parallel to the upper release frame edge 9 and symmetrically arranged with respect to the longitudinal centerline of the upper frame edge 9, forming a corresponding position-limiting snap-fit device.
[0022] The projected height of the clip slot 2 on the end view or side view of the joist body is 1-18 mm, and its setting size is based on ensuring that the joist body can be installed in the corresponding adaptive clamping connection device connected to the bed edge.
[0023] In Example 2 of the present invention, the widths of the upper open frame edge and the lower frame edge are 63 and 51 mm respectively, the width of the left and right frame edges is about 68 mm, the width of the recessed portions of the left and right frame edges is about 23 mm, the widths of the left and right frame edge bodies 9a of the upper frame edge, i.e., the open frame edge, are about 7 mm respectively, the width of the adaptive expansion opening is about 9 mm, and the height of the support beam body from the upper frame edge to the lower frame edge is about 90 mm. The remaining structures and corresponding manufacturing processes of this example are similar to those of the above-mentioned embodiments. The lower frame edge can be set to an arc-shaped frame edge. The left and right parts of the adaptive expansion opening of the support beam body can be symmetrical or asymmetrical.
[0024] In Example 3 of the present invention, the arrangement of the frame edges on the two opposite sides is approximately S-shaped, and one end of the S-shaped frame edges on the two opposite sides is respectively connected to the two opposite ends of the frame edge on the side of the joist body on the cross section with the adaptive expansion opening, and the other ends of the S-shaped frame edges on the two opposite sides are respectively connected to the two ends of the similar U-shaped frame edge on the other end of the joist body on the cross section, and the S-shaped frame edges on the two opposite sides are respectively inclined inward from the side with the adaptive expansion opening toward the direction of the similar U-shaped frame edge. The shape of the similar U-shaped frame edge is the shape of the bottom end part of the U shape. The left and right side parts of the adaptive expansion opening of the joist body can be symmetrical or not completely symmetrical. The other relevant component device structures and their connection structure connection methods of this example are similar to those of the above-mentioned embodiments.
[0025] Specific assembly connection: The two ends of the firmly connected bed board joist are respectively connected between the bed edges on both sides through their adaptive tensioning connection devices, etc., and cooperate with the adaptive clamping connection devices of the bed edge.
[0026] That is, the two ends of the firmly connected bed board joist are respectively inserted into the adaptive tightening openings 14a and the accommodating connection recesses 14b of the bed edges at both ends, and the tensioning side edges 7a of the upper parts of the left and right side frame edges of the firmly connected bed board joist and the upper open frame edges 9 are tensionedly connected to the locking connection slots 15 of the bed edge 11, and the convex locking cards 18 of approximately right-angled wedges, right-angled triangles, rectangles, etc. on the opposite sides of the locking connection slots 15 are snapped into and locked in the locking slots 3 of the firmly connected bed board joist; the firmly connected bed board joist The snap slot hole 2 on the lower side frame edge of the beam is snapped into the snap connector 17 of the bed edge through the limiting connection slot 16 of the limiting snap connecting edge 13b of the bed edge; the locking connection slot 15 and the protruding lock card 18 of the bed edge tension, position, lock and fix the two side frame edges and open frame edges 9 of the firmly connected bed board support beam; the snap connector 17 of the Z-shaped curved edge of the bed edge, the side walls of the free side horizontal edges 13b1 on both sides of the limiting connection slot 16, and the connecting side horizontal edges 13b3 support the firmly connected bed board support beam by snapping, locking, limiting and fixing the connection.
[0027] The bed edge and the securely connected bed joist are connected by adaptive expansion openings 6 of the securely connected bed joist and adaptive tightening openings 14a of the bed edge, or by a connection recess 14b. By utilizing the stress of the materials of the bed edge and the securely connected bed joist, the bed edge and the securely connected bed joist are securely and securely secured in an all-directional, three-dimensional, and all-around manner. This ensures that the bed edge and the securely connected bed joist remain securely and securely fixed even after extended use, without any unusual noise or other issues.
[0028] The adaptive expansion openings, in conjunction with the tensioned side edges, expand through stress to form an adaptive, self-tightening, locking connection with the corresponding bed edge. This connection is exceptionally strong, stable, and reliable. The bed joists themselves are exceptionally strong, the manufacturing process is simple, and installation and assembly are exceptionally easy.
[0029] As shown in Figures 8-9, in Example 4, the bed board joist that is firmly connected, that is, the joist body, includes an open frame 1, a pressure-bearing buffer device 10, and the like.
[0030] The pressure-bearing buffer device 10 is arranged on the bed board joist that is firmly connected. The pressure-bearing buffer device includes an elastic pressure-bearing plate 10a, an elastic buckle 10c, and an elastic connector 10b. The elastic buckle 10c is connected to the outer wall surface of the upper side frame edge 9 of the bed board joist that is firmly connected, the elastic buckle 10c is connected to the inner wall surface of the convex edge 5 of the upper side frame edge 9 of the bed board joist that is firmly connected, and the elastic connector 10b is connected between the elastic pressure-bearing plate and the elastic buckle. In this example, the elastic pressure-bearing plate 10a, the elastic buckle 10c and the elastic connector 10b are made of rubber or silicone material and molded into one piece, and the cross-section of the elastic buckle is in the shape of a groove plate. The length and width of the pressure-bearing buffer device can be adapted to the corresponding length and width of the bed board joist that is firmly connected. The open frame is connected to the pressure-bearing buffer device to form a composite bed board joist that is firmly connected. The corresponding bed board can be placed freely or connected to the elastic pressure plate of the bed board joist to which it is firmly connected in the known way.
[0031] In embodiment 5, the bottom wall surface and the two opposite side walls of the groove-plate-shaped elastic fastening body 10c respectively abut against the convex edge 5 connected to the upper side frame edge and its inner wall surface.
[0032] In Example 6, when a rigid connector is used, the connection structure and connection method between the rigid connector, the elastic pressure-bearing plate, and the elastic buckle body can be similar to those in the prior art.
[0033] In embodiment 7, the elastic fastening body 10c is in the shape of a flat plate.
