Reinforcement bar structure for furniture frame

Abstract

A reinforcement bar structure for a furniture frame, structurally comprising a tube body (11), lower engagement slots (1) and inverted-L-shaped notch units (2). In the reinforcement bar structure, the tube body (11) with a large vertical dimension and the inverted-L-shaped notch units (2) with a shallow vertical cutting depth can be realized simultaneously, thereby ensuring that the reinforcement bar structure has high structural strength. The vertical cutting depth of the inverted-L-shaped notch units (2) is less than the vertical dimension of side panels of side longitudinal beams (a) and middle longitudinal beams (b), and the remaining portions of the longitudinal beams below the inverted-L-shaped notch units (2) engage with the lower engagement slots (1), so that it is difficult for the longitudinal beams to separate and move away from each other, preventing the tube body (11) from falling off easily.

Description

A reinforcing frame structure for a furniture frame body TECHNICAL FIELD

[0001] The present application belongs to the technical field of furniture structure, and particularly relates to a reinforcing frame structure for a furniture frame body. BACKGROUND

[0002] The common bed frame body and sofa frame body mainly include a supporting leg, a frame plate, an intermediate plate and a reinforcing cross plate. The intermediate plate of a single bed or a sofa with a relatively small width size is generally single, and the length of the reinforcing cross plate corresponds to the width of the frame body.

[0003] The intermediate plate of a double bed with a relatively large width size is generally a cross-shaped plate. At this time, the length of the reinforcing cross plate can be half of the width of the frame body. The reinforcing frame mentioned above refers to the reinforcing cross plate.

[0004] In addition, all the above-mentioned "plate" structures can be replaced by rectangular square tube structures. At this time, the furniture frame body is a steel frame structure.

[0005] For example, the Chinese utility model patent with the authorization announcement number CN211533542U and the authorization announcement date of September 22, 2020 discloses a portable assembled bed frame, which comprises two frame structure supporting frames and a bed plate frame. The bed plate frame comprises two side longitudinal beams and a plurality of cross beams. The side longitudinal beam comprises two longitudinal beam units and a first supporting foot. A first connecting groove is arranged at the upper end of the first supporting foot. One end of the longitudinal beam unit is locked on the supporting frame by a first bolt. The other end of the longitudinal beam unit is locked in the first connecting groove by a second bolt and a second nut. The longitudinal beam unit is a hollow square tube, and a plurality of mounting holes are arranged at the upper end of the longitudinal beam unit. The end of the cross beam is embedded in the mounting hole. A flexible buffer is arranged at the connection between the cross beam and the mounting hole.

[0006] The assembled bed frame in the utility model patent has the advantages of simple and convenient installation and disassembly, portability and good flexibility.

[0007] However, the assembled bed frame has at least the following two deficiencies in actual use, which are also the technical problems to be solved by the present application, i.e.

[0008] Firstly, the installation mode of the cross beam structure, i.e. the reinforcing frame, is clamping the mounting hole. Therefore, if the vertical size of the cross beam is large, the opening depth of the mounting hole also needs to be relatively large, which will reduce the structural strength of the side longitudinal beam. On the contrary, if the opening depth of the mounting hole is small, only the cross beam with a small vertical size can be matched, and the structural strength of the cross beam itself is insufficient, which is obviously a structural defect.

[0009] Second, the above beam structure, which has no length direction on the mounting port limit function, in other words, once 2 side edge longitudinal beam because of deformation and away from each other, the beam is easy to fall, which is very dangerous.

[0010] Therefore, in view of the above, there is an urgent need for a new type of reinforcing structure with more efficient and safe two-end mounting method to be used on various types of disassembled furniture steel frames. SUMMARY

[0011] The present application provides a reinforcing structure for furniture frame, which comprises a pipe body, a lower clamping groove, and a reverse L-shaped slot unit, so that: 1, the reinforcing structure can realize a pipe body with a larger vertical size and a reverse L-shaped slot unit with a smaller vertical opening depth at the same time, ensuring that the reinforcing structure has a larger structural strength; 2, the vertical opening depth of the reverse L-shaped slot unit is smaller than the vertical size of the side plate of the edge longitudinal beam and the intermediate longitudinal beam, and the part of the longitudinal beam below the reverse L-shaped slot unit is clamped in the lower clamping groove, so that the longitudinal beams are difficult to open away from each other, and the pipe body is not easy to fall.

[0012] The technical scheme adopted by the present application to solve the above problems is: a reinforcing structure for furniture frame, comprising a pipe body, at least one lower clamping groove provided at one end of the pipe body and opened on the bottom plate and two side plates of the pipe body, and a reverse L-shaped slot unit provided on the top plate and side plate of the edge longitudinal beam and / or intermediate longitudinal beam and used for clamping the lower clamping groove.

[0014] A further preferred technical scheme is that the reverse L-shaped slot unit comprises a horizontal-vertical two-sided slot body for downwardly inserting the end of the pipe body.

[0015] A further preferred technical scheme is that the reverse L-shaped slot unit further comprises a reserved plate provided on the horizontal bottom surface of the horizontal-vertical two-sided slot body and used for inserting into the lower clamping groove.

[0037] The following description is only the preferred embodiment of the present application, and does not limit the scope of the present application.

[0038] As shown in FIGS. 1-10, a reinforcing structure for a furniture frame body includes a pipe body 11, further including a lower clamping groove 1 provided at one end of the pipe body 11 and opened on the bottom plate and two side plates of the pipe body 11, and an inverted L-shaped slot unit 2 provided on the top plate and side plate of the edge longitudinal beam a and / or the intermediate longitudinal beam b and used for clamping the lower clamping groove 1.

[0039] In the present embodiment, the reinforcing structure is composed of the pipe body 11, the lower clamping groove 1 and the inverted L-shaped slot unit 2. The number of the lower clamping groove 1 is one or two, and the inverted L-shaped slot unit 2 can be provided on the edge longitudinal beam a, the intermediate longitudinal beam b, or the extension structure of the above two longitudinal beams, or even on the support leg or the support frame. As long as the lower clamping groove 1 and the inverted L-shaped slot unit 2 are provided in pairs, the former can be clamped downwardly to the latter.

[0040] The pipe body 11 can also be replaced by a solid plate. Before the replacement, the inverted L-shaped slot unit 2 is cut out from the pipe body as an L-shaped sheet, and after the replacement, it is excavated from the plate body as an L-shaped block. Both of the above methods can effectively clamp the lower clamping groove 1.

[0041] In addition, the vertical opening depth of the lower clamping groove 1 needs to be matched with the vertical opening depth of the inverted L-shaped slot unit 2 to ensure that the upper surface of the pipe body 11 is flush with the upper surface of the longitudinal beam, thereby improving the use comfort of the furniture frame body.

[0042] Finally, the transverse opening size of the lower clamping groove 1 also needs to be matched with the indentation size of the lower clamping groove 1 on the end face of the pipe body 11, so that when the lower clamping groove 1 clamps the inverted L-shaped slot unit 2, the end face of the pipe body 11 just abuts against the side edge of the inverted L-shaped slot unit 2 on the top plate of the longitudinal beam, which can also improve the clamping stability of the end of the pipe body 11.

[0043] Correspondingly, the transverse width of the inverted L-shaped slot unit 2 also needs to correspond to the transverse thickness size of the pipe body 11 to try to ensure that the pipe body 11 is difficult to loosen in all directions except the upward direction in the inverted L-shaped slot unit 2.

[0044] Further comprising a bevel cutout clamping block unit 3 arranged at the end of the pipe body 11, and an opening 4 arranged on the side plate of the side longitudinal beam a and / or the intermediate longitudinal beam b and used for inserting the bevel cutout clamping block unit 3.

[0045] In the embodiment, the first structure of the pipe body 11 is that the lower clamping groove 1 is arranged at both ends. At this time, the inverted L-shaped slot unit 2 is arranged on the inner side plate of the side longitudinal beam a, and the inverted L-shaped slot unit 2 is arranged on the side plates of the intermediate longitudinal beam b.

[0046] The second structure of the pipe body 11 is that the bevel cutout clamping block unit 3 is arranged at one end, and the lower clamping groove 1 is arranged at the other end. At this time, the opening 4 and the inverted L-shaped slot unit 2 are arranged on the opposite side plates of the side longitudinal beam a and the intermediate longitudinal beam b, or the opposite side plates of the two side longitudinal beams a.

[0047] At this time, the left and right positions of the opening 4 and the inverted L-shaped slot unit 2 are not limited, and the pipe body 11 is first inserted into the bevel cutout clamping block unit 3 and the opening 4 in an inclined manner during installation, and then the lower clamping groove 1 and the inverted L-shaped slot unit 2 are buckled downward.

[0048] Even for the intermediate longitudinal beam b, the inverted L-shaped slot unit 2 is arranged on one side, and the opening 4 is arranged on the other side.

[0049] The inverted L-shaped slot unit 2 comprises a horizontal-vertical two-sided groove body 201 for downwardly inserting the end of the pipe body 11.

[0050] In the embodiment, the horizontal-vertical two-sided groove body 201 is the space structure left after the L-shaped sheet is cut, and it can be fully clamped and fixed with the lower clamping groove 1.

[0051] The inverted L-shaped slot unit 2 further comprises a reserved plate 202 arranged on the horizontal bottom surface of the horizontal-vertical two-sided groove body 201 and used for inserting into the lower clamping groove 1.

[0052] In the embodiment, the "reserved" of the reserved plate 202 means that the vertical plate part of the sheet is not completely cut off when the L-shaped sheet is cut, and only the "thin strips" on both sides are cut off. Please refer to FIG. 10 for details.

[0053] At this time, if the width and vertical length of the reserved plate 202 are relatively small, the stable installation effect of the pipe body 11 will not be significantly affected. However, as long as the width and vertical length are properly set, the pipe body 11 can be further reinforced, which is very practical.

[0054] It should be noted that: when the tube body 11 has been replaced with a solid plate body, in order to ensure the effective use of the reserved plate 202, when the lower slot 1 is opened, a cavity needs to be opened inside the plate body and inside the lower slot 1, rather than just cutting out a thin slice at the lower slot 1.

[0055] The vertical side surface of the reserved plate 202 is arranged on the inner side surface of the tube body 11 .

[0056] In this embodiment, the outer side surface of the tube body 11 abuts against the side surface of the horizontal and vertical double-sided groove body 201 , which is the first left and right limiting effect of the tube body 11 .

[0057] When the width of the reserved plate 202 is relatively large and appropriate, it can clamp the inner side surface of the tube body 11 and become the second left and right limiting effect of the tube body 11, which can further strengthen the tube body 11.

[0058] The upper surface of the reserved plate 202 is arranged on the inner top surface of the tube body 11 .

[0059] Similarly, in this embodiment, when the "reserved height" of the reserved plate 202 is relatively large, it can support the inner top surface of the tube body 11, and cooperate with the original effect of the bottom edge of the horizontal and vertical two-sided groove body 201 supporting the lower slot 1, thereby further reinforcing the tube body 11 in the vertical direction.

[0060] The oblique cut block unit 3 includes a U-shaped block 301 provided on the end surface of the tube body 11 and an oblique cut 302 provided on the upper surface of the U-shaped block 301 for obliquely inserting the tube body 11 into the opening 4 .

[0061] In this embodiment, the setting method of the U-shaped block 301 is similar to that of the reserved plate 202, and the preferred method is to "retain" the U-shaped block 301 after opening the end portion close to the upper incision. The method of welding the U-shaped block 301 on the original end face of the tube body 11 is relatively troublesome.

[0062] On the other hand, since the space left for the tube body 11 between the two side longitudinal beams a, or between the side longitudinal beam a and the middle longitudinal beam b, corresponds to its length, the connection method of the oblique cut block unit 3 and the opening 4 cannot be installed downward like the lower slot 1 and the inverted L-shaped slot unit 2.

[0063] Therefore, the installation mode of the pipe body 11 at this time can only be: first, insert the bevel cut block unit 3 and the opening 4 obliquely, then rotate the pipe body 11 downward, and finally buckle the lower clamping groove 1 and the inverted L-shaped slot unit 2. Therefore, the size of the bevel cut block unit 3 cannot be strictly matched with the opening 4, which is the function of the bevel cut 302 for misalignment.

[0064] In addition, the bevel cut 302 for misalignment can also be opened together with the upper end cut, without the need for further cutting on the U-shaped block 301 which is in a vertical cross-section in a rectangular shape.

[0065] Finally, if the pipe body 11 is replaced by a solid plate body, the shape of the U-shaped block 301 is a right trapezoidal block.

[0066] The opening 4 is arranged on the side plate of the side longitudinal beam a or the intermediate longitudinal beam b.

[0067] In the embodiment, the size-structure strength relationship of the opening 4 and the bevel cut block unit 3 still has the feature of “this consumes the other”. Therefore, the horizontal and vertical edge size of the opening 4 is preferably 40-60% of the vertical size of the longitudinal beam.

[0068] The inverted L-shaped slot unit 2 is arranged in pairs on the intermediate longitudinal beam b.

[0069] In the embodiment, the left and right pairs of inverted L-shaped slot units 2 can also be staggered, and both are relatively independent in structure and function.

[0070] The two pairs of inverted L-shaped slot units 2 penetrate the top plate of the intermediate longitudinal beam b.

[0071] In the embodiment, when the two pairs of inverted L-shaped slot units 2 are aligned and penetrate the top plate of the intermediate longitudinal beam b, the opening method is to cut off a “U-shaped thin steel sheet” as a whole.

[0072] At this time, whether to arrange the reserved plate 202 in the two inverted L-shaped slot units 2 and how to set the size of the reserved plate 202 are independent of each other.

[0073] The embodiments of the application are described in detail above in combination with the drawings, but the application is not limited to the above embodiments, and various modifications can be made within the knowledge of ordinary skilled in the art without departing from the purpose of the application. These are not creative modifications, and are protected by the patent law within the scope of the claims of the application.
