Description

[Technical field]

[0001] The present invention relates to the technical field of furniture, and in particular to a connecting component for furniture, a supporting frame and furniture. [Background technology]

[0002] Existing furniture includes a main body and a support frame for supporting the main body. The main body can be a mattress, a sofa cushion, a table top, a seat board, etc. In order to facilitate transportation, the existing support frame is a detachable support frame, which usually includes a plurality of support rods and a plurality of connecting plates. The support rods form a first component, and the connecting plates form a second component. Users assemble the plurality of support rods and the plurality of connecting plates to form a support frame by screws. However, in this case, users must use tools to assemble it, which makes the installation of the support frame very inconvenient. [Summary of the invention]

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a connecting component, a support frame and furniture for furniture, which can complete the assembly of the first component, the compensation plate and the second component without the aid of tools, so that the assembly of the connecting component is more convenient. In addition, the connection reliability of the first component and the second component can be ensured to avoid shaking of the two.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A connecting component for furniture comprises a first component, a second component and a compensation plate, wherein the first component is provided with a slot, the second component comprises an inserting portion, the inserting portion is inserted into the slot along a first direction and an assembly gap exists between the inserting portion and the slot, the compensation plate comprises a compensation portion and a limiting portion connected to each other, the compensation portion is interference fit with the assembly gap so that the inserting portion is fixed in the slot, and the limiting portion is confined in the slot by the force applied by the inserting portion along the first direction.

[0006] After the connecting member in the present invention is assembled, the limiting part is restricted in the slot by the force applied by the plug-in part along the first direction, thereby preventing the limiting part from falling out of the slot, that is, preventing the compensating part connected thereto from falling out of the assembly gap, thereby ensuring the connection reliability between the plug-in part and the slot; in addition, during assembly, when the plug-in part of the second member is inserted into the slot along the first direction, since the limiting part is subjected to the force applied by the plug-in part along the first direction, the limiting part will be driven by the plug-in part along the first direction, thereby driving the compensating part to be inserted into the slot along the first direction, that is, the assembly of the compensating sheet can be completed while the plug-in part is inserted into the slot, thereby reducing the difficulty of inserting the compensating sheet, and the entire assembly process can be completed without the aid of tools. The assembly of the first component, the compensation sheet and the second component makes the assembly of the connecting component more convenient. In addition, the connection reliability of the first component and the second component can be ensured to avoid shaking of the two. Especially when the first direction is the downward direction of gravity, the gravity applied by the main body to the second component and the gravity of the user himself acting on the second component through the main body can be used to make the compensation sheet always maintain an interference fit with the assembly gap to further improve the connection reliability of the second component and the first component; finally, the material of the compensation sheet can be different from that of the first component and the second component. Since the interference is provided by the compensation part, it is only necessary to make the compensation part have a certain toughness. In this way, the range of material selection for the first component and the second component can be wider.

[0007] In the above-mentioned furniture connection member, the limiting part includes a limiting piece arranged between the bottom of the slot and the bottom of the plug-in part, one end of the compensation part is connected to the limiting piece, and the other end extends in the opposite direction of the first direction and extends into the assembly gap. With such a design, the compensation piece can be pre-installed in the slot or on the plug-in part, and there is no need to limit the assembly order of the compensation piece, so the assembly is convenient, and in addition, it is also convenient to replace the compensation piece separately later.

[0008] In the above-mentioned furniture connection component, the compensation sheet includes two compensation parts arranged opposite to each other, and the limiting sheet is connected between the two compensation parts. Such a design can ensure the consistency of the insertion positions of the plug-in parts at both ends of the second component, and at the same time, the compensation sheet can be half-surrounded on the outside of the plug-in part, which can not only improve the limiting effect of the plug-in part on the limiting sheet, but also enable the compensation sheet to be pre-wrapped on the outside of the plug-in part and then inserted into the slot together with the plug-in part, so as to further reduce the difficulty of assembling the connection component.

[0009] In the above-mentioned furniture connection member, the limiting piece has an unfolded natural state and a bent state, and the limiting piece is half-surrounded on the plug-in part in the bent state. Such a design is not only conducive to the processing and forming of the limiting piece in the natural state and the transportation and packaging, but also allows the limiting piece to be bent into a matching shape according to the shape of the bottom of the plug-in part during use, thereby improving the versatility of the compensation piece.

[0010] In the above-mentioned furniture connection member, the compensation sheet further includes a folded portion, which has an unfolded natural state and a bent state, and the limiting sheet is connected to the compensation portion via the folded portion. Such a design is not only conducive to the processing and forming of the limiting sheet in its natural state and the transportation and packaging, but also enables the folded portion to be bent into a matching shape according to the shape of the connecting corner between the bottom of the plug-in portion and the side portion during use (for the case where the cross-sectional shape of the plug-in portion is a rectangle), so as to improve the versatility of the compensation sheet.

[0011] In the above-mentioned furniture connection member, the thickness of the folded portion is smaller than the thickness of the limiting piece and the thickness of the compensation portion. Such a design not only enables the user to identify the folded portion for bending the folded portion, but also makes the bending of the folded portion more labor-saving.

[0012] In the above-mentioned furniture connection member, the limiting part includes a limiting boss convexly arranged on the side of the compensation part facing the plug-in part, the plug-in part is provided with a limiting hole, and the limiting boss is inserted into the limiting hole; and / or, the limiting part includes a limiting hole arranged on the compensation part, and the plug-in part is provided with a limiting boss inserted into the limiting hole. With such a design, the limiting boss can be inserted into the limiting hole in advance, so that the compensation sheet is fixed on the plug-in part, and the compensation sheet is prevented from falling off during the subsequent insertion of the plug-in part into the slot, thereby further reducing the difficulty of assembling the connection member and facilitating the separate replacement of the compensation sheet at a later time.

[0013] In the above-mentioned furniture connection member, the limiting boss and the limiting hole are interference-fitted. Such a design can prevent the compensating sheet from shaking relative to the plug-in portion, thereby ensuring the accuracy of the installation position of the compensating sheet.

[0014] In the above-mentioned furniture connection member, the plug-in portion drives the compensation portion to be inserted into the slot through the limiting portion, and the interference between the compensation portion and the assembly gap increases as the insertion depth of the compensation portion increases. With such a design, as the plug-in portion is inserted deeper into the slot, the interference between the compensation portion and the assembly gap gradually increases, that is, the matching between the compensation portion, the slot and the plug-in portion becomes more and more compact, thereby further improving the connection reliability between the plug-in portion and the slot, and avoiding failure of the connection between the plug-in portion and the slot during use.

[0015] In the above-mentioned furniture connection component, one of the side of the compensation part away from the plug-in part and the side wall of the slot is provided with a groove, and the other is provided with a protrusion, and the protrusion is inserted into the groove along the first direction or the reverse direction thereof. With such a design, the plug-in position of the plug-in part can be positioned by the cooperation of the protrusion and the groove, so as to ensure the accuracy of the plug-in position of the plug-in part; in addition, the protrusion or the groove structure is provided on the compensation part, so as to avoid processing on the plug-in part, thereby simplifying the processing technology of the second component.

[0016] In the above-mentioned furniture connection component, the protrusion has a first protruding surface away from the provided side surface, and the groove has a first concave surface that is interference-fitted with the first protruding surface, and the interference between the first protruding surface and the first concave surface increases as the insertion depth of the plug-in portion increases. With such a design, when the first direction is the downward gravity direction, the gravity applied by the body to the second component and the gravity of the user himself acting on the second component through the body can be used to make the plug-in portion insert deeper into the slot, which also makes the protrusion insert deeper into the groove, and the interference between the first protruding surface and the first concave surface gradually increases, that is, the matching of the compensation part with the plug-in portion and the slot becomes more and more compact, thereby further improving the connection reliability between the plug-in portion and the slot, and avoiding the failure of the connection between the plug-in portion and the slot during use.

[0017] In the above-mentioned furniture connection component, the height of the first convex surface protruding from the provided side surface gradually decreases along the first direction, and the concave depth of the first concave surface gradually decreases along the first direction. Such a design can simplify the processing difficulty of the first convex surface and the first concave surface, so as to facilitate the processing and forming of the convexity and the concave groove.

[0018] In the above-mentioned furniture connection member, the protrusion has a second protruding surface connected between the first protruding surface and the provided side surface, and the groove has a second concave surface that is interference-fitted with the second protruding surface, and the interference between the second protruding surface and the second concave surface increases as the insertion depth of the plug-in portion increases. In this way, the tightness of the protrusion and the groove can be further increased, so as to improve the connection reliability between the compensation portion and the slot.

[0019] In the above-mentioned furniture connection member, the second member extends along the second direction, the first direction intersects the second direction, the slot has a clearance opening for evading the second member, and the protrusion cooperates with the groove to limit the plug-in portion in the second direction. Such a design can prevent the plug-in portion from escaping from the slot along the second direction from the clearance opening, thereby further improving the connection reliability between the plug-in portion and the slot.

[0020] In the above-mentioned furniture connection member, the side wall of the slot is provided with a groove, the compensation part is inserted into the groove along the first direction, and the interference between the compensation part and the assembly gap increases as the insertion depth of the compensation part increases. Such a design can simplify the structure of the compensation part, thereby simplifying the processing technology of the compensation sheet.

[0021] The present invention also provides a support frame for furniture, comprising a plurality of support rods, the support frame comprising the connecting member described in any of the above technical solutions, the support rods forming the second member, and the plurality of support rods connected through a plurality of first members and compensation sheets to form the support frame. Such a design can make the assembly of the support frame more convenient, thereby improving the user experience.

[0022] In the above-mentioned furniture support frame, the support frame is a bed frame, and the plurality of first components include at least one of an L-shaped insert, a straight-line insert, a T-shaped insert, and a cross-shaped insert, wherein the L-shaped insert is provided with two vertically distributed slots; the straight-line insert includes two straight-line distributed slots; the T-shaped insert is provided with three T-shaped distributed slots; and the cross-shaped insert is provided with four cross-shaped distributed slots. With such a design, first components of different shapes can be configured according to the distribution of support rods in the bed frame to meet different bed frame assembly requirements.

[0023] In the above-mentioned furniture support frame, the support frame also includes a support leg for supporting the first component, the first component is provided with an insertion block extending downward, and the top of the support leg is provided with a socket for inserting the insertion block.

[0024] The present invention also provides a piece of furniture, comprising a main body and a support frame for supporting the main body, wherein the support frame is the support frame described above.

[0025] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

[0053] Embodiment 1

[0054] like Figures 1 to 14 As shown, the furniture connecting component of this embodiment includes a first component 100, a second component 200 and a compensation sheet 300. The first component 100 is provided with a slot 110. The second component 200 includes a plug-in portion 210. The plug-in portion 210 is inserted into the slot 110 along a first direction Z and there is an assembly gap between the slot 110. The assembly gap is the gap between the slot side wall and the plug-in portion 210. The compensation sheet 300 includes a compensation portion 310 and a limiting portion 320 connected to each other. The compensation portion 310 is interference fit with the assembly gap so that the plug-in portion 210 is fixed in the slot 110. The limiting portion 320 is confined in the slot 110 by the force applied by the plug-in portion 210 along the first direction Z.

[0055] After the connecting member of the present invention is assembled, the limiting portion 320 is limited in the slot 110 by the force applied by the plug-in portion 210 along the first direction Z, thereby preventing the limiting portion 320 from escaping from the slot 110, that is, preventing the compensation portion 310 connected thereto from escaping from the assembly gap, thereby ensuring the connection reliability between the plug-in portion 210 and the slot 110; in addition, during assembly, when the plug-in portion 210 of the second member 200 is inserted into the slot 110 along the first direction Z, since the limiting portion 320 is subjected to the force applied by the plug-in portion 210 along the first direction Z, the limiting portion 320 will be driven by the plug-in portion 210 along the first direction Z, thereby driving the compensation portion 310 to be inserted into the slot 110 along the first direction Z, that is, the assembly of the compensation sheet 300 can be completed while the plug-in portion 210 is inserted into the slot 110, thereby reducing the difficulty of inserting the compensation sheet 300, and the entire assembly process can be completed without the aid of tools. 300 and the second component 200, thereby making the assembly of the connecting components more convenient. In addition, it can ensure the connection reliability of the first component 100 and the second component 200 and avoid shaking of the two. Especially when the first direction Z is the downward gravity direction, the gravity applied by the main body to the second component 200 and the gravity of the user himself acting on the second component 200 through the main body can be used to make the compensation sheet 300 always maintain an interference fit with the assembly gap, so as to further improve the connection reliability of the second component 200 and the first component 100; finally, the material of the compensation sheet 300 can also be different from that of the first component 100 and the second component 200. Since the interference is provided by the compensation part 310, it is only necessary to make the compensation part 310 have a certain toughness. In this way, the material selection range for the first component 100 and the second component 200 can be wider, that is, the first component 100 and the second component 200 can both choose harder materials to increase the structural strength of the two.

[0056] Specifically, the limiting portion 320 in this embodiment includes a limiting plate 321, the slot 110 has a slot and a slot bottom that are relatively arranged, the plug-in portion 210 is inserted into the slot 110 through the slot along the first direction Z, and the limiting plate 321 is arranged between the slot bottom of the slot and the bottom of the plug-in portion 210, one end of the compensation portion 310 is connected to the limiting plate 321, and the other end extends in the opposite direction of the first direction Z and is inserted into the assembly gap. With such a design, the compensation plate 300 can be pre-installed in the slot 110 or on the plug-in portion 210 without limiting the assembly order of the compensation plate 300, so the assembly is convenient. In addition, it is also convenient for the individual replacement of the compensation plate 300 at a later time.

[0057] Preferably, there are two compensation parts 310, which are arranged opposite to each other and located on opposite sides of the plug-in part 210, and the limiting piece 321 is connected between the two compensation parts 310. Such a design can ensure the consistency of the insertion positions of the plug-in parts 210 at both ends of the second member 200, prevent the second member 200 from tilting, and improve the limiting effect of the plug-in part 210 on the limiting piece 321. In addition, the compensation piece 300 can be pre-wrapped in a U shape outside the plug-in part 210 and then inserted into the slot 110 together with the plug-in part 210, so as to further reduce the difficulty of assembling the connecting member, which is not only convenient for assembly, but also convenient for the separate replacement of the compensation piece 300 at a later stage.

[0058] It is understandable that in other embodiments of the present invention, the limiting plate can also be pre-installed in the slot, and then the plug-in part is inserted and the compensation plate is half-wrapped on the outside of the plug-in part, and then the second component is pressed along the first direction Z to drive the compensation plate to be inserted into the slot together.

[0059] The cross section of the second component 200 in this embodiment is rectangular. Due to the existence of processing errors, the bottom corner sizes of the second components 200 in the same batch are different. In order to make the compensation sheet 300 adapt to the second components 200 of different cross-sectional sizes, the compensation sheet 300 in this embodiment also includes a folded portion 330. The folded portion 330 has a natural state of unfolding (such as Figure 8 ) and in a bent state (as shown) Figure 3 As shown), the limiting plate 321 is connected to the compensation portion 310 via the folding portion 330. Such a design is not only conducive to the processing and forming of the limiting plate 321 in a natural state and the transportation and packaging of the compensation plate 300, but also enables the folding portion 330 to be bent into a matching shape according to the shape of the connecting corner between the bottom and the side of the plug-in portion 210 during use, so as to improve the versatility of the compensation plate 300.

[0060] Preferably, the compensation sheet 300 in this embodiment is a plastic part with a certain flexibility, and the side of the compensation sheet 300 away from the plug-in portion 210 is partially cut off, so that the thickness of the folded portion 330 is smaller than the thickness of the limiting sheet 321 and the thickness of the compensation portion 310. Such a design not only enables the user to identify the folded portion 330 to facilitate bending the folded portion 330, but also makes the bending of the folded portion 330 more labor-saving.

[0061] It can be understood that in other embodiments of the present invention, the compensation sheet may also be a metal piece with a certain flexibility.

[0062] It can be understood that in other embodiments of the present invention, the compensation sheet may also be in a fixed shape that matches the cross-sectional shape of the plug-in portion.

[0063] In addition, the plug-in part 210 in this embodiment drives the compensation part 310 to be inserted into the slot 110 through the limiting part 320, and the interference between the compensation part 310 and the assembly gap increases as the insertion depth of the compensation part 310 increases. With such a design, as the plug-in part 210 is inserted deeper into the slot 110, the interference between the compensation part 310 and the assembly gap can be gradually increased, that is, the matching between the compensation part 310, the slot 110 and the plug-in part 210 becomes more and more compact, thereby further improving the connection reliability between the plug-in part 210 and the slot 110, and avoiding the failure of the connection between the plug-in part 210 and the slot 110 during use.

[0064] In order to ensure the accuracy of the plug-in position of the plug-in part 210, in this embodiment, a protrusion 400 is provided on the side of each compensation part 310 away from the plug-in part 210, and the two side walls of the slot 110 are provided with a groove 500 extending from the notch toward the bottom of the groove. The protrusion 400 is inserted into the groove 500 along the first direction Z, and the protrusion 400 has a first convex surface 410 away from the side of the compensation part 310, and the groove 500 has a first concave surface 510 that is interference-fitted with the first convex surface 410. The interference between the first convex surface 410 and the first concave surface 510 increases with the increase of the insertion depth of the plug-in part 210. With such a design, the plug-in position of the plug-in part 210 can be positioned by the cooperation between the protrusion 400 and the groove 500 to ensure the accuracy of the plug-in position of the plug-in part 210; in addition, the protrusion 400 By arranging the compensation portion 310 and arranging the groove 500 on the side wall of the slot, processing on the plug-in portion 210 can be avoided, thereby simplifying the processing technology of the second component 200; in addition, when the first direction Z is the downward gravity direction, the gravity applied by the main body to the second component 200 and the gravity of the user himself acting on the second component 200 through the main body can be utilized, so that the plug-in portion 210 can be inserted deeper and more smoothly into the slot 110, and the protrusion 400 can be inserted deeper into the groove 500, and the interference fit between the first protruding surface 410 and the first recessed surface 510 gradually increases, that is, the matching of the compensation portion 310 with the plug-in portion 210 and the slot 110 becomes more and more compact, thereby further improving the connection reliability between the plug-in portion 210 and the slot 110, and avoiding failure of the connection between the plug-in portion 210 and the slot 110 during use.

[0065] In order to achieve that the interference between the first convex surface 410 and the first concave surface 510 increases with the insertion depth of the plug-in portion 210, in this embodiment, the height of the first convex surface 410 protruding from the provided side surface gradually decreases along the first direction Z, so that the distance between the two first convex surfaces 410 gradually decreases along the first direction Z, and the concave depth of the first concave surface 510 gradually decreases along the first direction Z, so that the distance between the two first concave surfaces 510 gradually decreases along the first direction Z, and the minimum distance between the two first convex surfaces 410 is greater than the minimum distance between the two first concave surfaces 510, and the maximum distance between the two first convex surfaces 410 is greater than the maximum distance between the two first concave surfaces 510. Such a design can not only make the compensation portion 310 smoothly inserted into the assembly gap, but also simplify the processing difficulty of the first convex surface 410 and the first concave surface 510, so as to facilitate the processing and forming of the protrusion 400 and the groove 500.

[0066] In addition, the protrusion 400 in this embodiment further has a second protrusion surface 420 connected between the first protrusion surface 410 and the provided side surface, the second protrusion surface 420 is provided on opposite sides of the first protrusion surface 410 and extends along the first direction Z, and the distance between the two second protrusion surfaces 420 gradually decreases along the first direction Z, that is, the protrusion 400 is an isosceles trapezoid with a larger upper part and a smaller lower part, and the groove 500 has a second concave surface 520 with an interference fit with the second protrusion surface 420, and the groove 500 is a larger upper part and a smaller lower part. The isosceles trapezoidal groove, the minimum distance between the two second raised surfaces 420 is greater than the minimum distance between the two second recessed surfaces 520, and the maximum distance between the two second raised surfaces 420 is greater than the maximum distance between the two second recessed surfaces 520, so that the interference between the second raised surfaces 420 and the second recessed surfaces 520 increases with the increase of the insertion depth of the plug-in part 210, so as to further increase the fitting tightness between the protrusion 400 and the groove 500, so as to improve the connection reliability between the plug-in part 210 and the slot 110.

[0067] In addition, when the compensation sheet 300 is pre-installed on the plug-in portion 210, in order to ensure the accuracy of the installation position of the compensation sheet 300, the limiting portion 320 in this embodiment also includes a limiting boss 322 protruding from the side of the compensation portion 310 facing the plug-in portion 210, and the plug-in portion 210 is provided with a limiting hole 211, and the limiting boss 322 is inserted into the limiting hole 211, wherein the limiting boss 322 is a waist-shaped boss or a round table, etc., and the corresponding limiting hole 211 is a waist-shaped hole or a round hole; with such a design, when the second component 200 is assembled with the first component 100, the limiting boss 322 can be inserted into the limiting hole 211 in advance, so that the compensation sheet 300 is fixed on the plug-in portion 210, so as to avoid the compensation sheet 300 from falling off and shaking relative to the plug-in portion 210 during the subsequent insertion of the plug-in portion 210 into the slot 110, thereby further reducing the difficulty of assembling the connecting component and facilitating the separate replacement of the compensation sheet 300 at a later time.

[0068] It can be understood that in other embodiments of the present invention, the limiting part also includes a limiting hole provided on the compensation part, and the plug-in part is provided with a limiting boss inserted into the limiting hole; or the limiting part also includes a limiting hole and a limiting boss provided on the compensation part, and the plug-in part is provided with a limiting boss that is plug-matched with the upper limit hole of the compensation part and a limiting hole that is plug-matched with the upper limit boss of the compensation part.

[0069] The limiting boss 322 in this embodiment has a root connected to the compensation part 310 and a top extending toward the plug-in part 210, the top is clearance-fitted with the limiting hole 211, and the root is interference-fitted with the limiting hole 211, and the interference fit of the two increases with the increase in the depth of the root inserted into the limiting hole 211. In this way, after the compensation sheet 300 is subjected to pressure in the first direction Z, the compensation part 310 will be squeezed by the side wall of the slot, and the squeezing of the compensation part 310 by the side wall of the slot will make the compensation part 310 close to the plug-in part 210 and further make the root continue to be inserted into the limiting hole 211, thereby making the limiting boss 322 and the limiting hole 211 more compactly embedded, thereby improving the connection reliability between the limiting boss 322 and the plug-in part 210.

[0070] In this embodiment, the second component 200 is a rod-shaped structure extending along the second direction X, the second direction X intersects with the first direction Z, and preferably, the plane where the second direction X is located is perpendicular to the first direction Z. The slot 110 has a avoidance opening 112 for avoiding the second component 200, that is, the second component 200 is arranged through the avoidance opening 112. In this way, the plug-in portion 210 can be limited in the second direction X and its reverse direction by the cooperation of the protrusion 400 and the groove 500, which can not only position the plug-in portion 210 to ensure the accuracy of the plug-in position of the plug-in portion 210 and the slot 110, but also prevent the plug-in portion 210 from escaping from the slot 110 along the second direction X from the avoidance opening 112, thereby further improving the connection reliability between the plug-in portion 210 and the slot 110.

[0071] It can be understood that in other embodiments of the present invention, the compensation plate only includes a limit plate and a compensation part, so that the compensation plate is L-shaped. With such a design, the plug-in part can be fixed in the slot through the interference fit of the single-sided assembly clearance between the compensation part and the slot and the plug-in part.
