BACKGROUND

[0002] The existing furniture includes a body and a support frame for supporting the body, the body can be a mattress, a sofa cushion, a table board, 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 member, and the connecting plates form a second member, and a user assembles the plurality of support rods and the plurality of connecting plates by means of screws to form the support frame, but in this way, the user must use tools to assemble, so that the installation of the support frame is very inconvenient.

SUMMARY

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

[0004] To solve the above technical problems, the present application adopts the following technical solutions:

[0005] A furniture connecting member includes a first member, a second member and a compensation piece, the first member is provided with a slot, the second member includes a plug-in part, the plug-in part is inserted into the slot along a first direction Z and there is an assembly gap between the plug-in part and the slot, the compensation piece includes a compensation part and a limiting part connected together, the compensation part is in interference fit with the assembly gap, so that the plug-in part is fixed in the slot, and the limiting part is limited in the slot by the force applied by the plug-in part along the first direction Z.

[0006] The limiting portion is limited in the insertion slot by the force applied by the insertion portion along the first direction Z, thereby preventing the limiting portion from coming out of the insertion slot, i.e., preventing the compensation portion connected thereto from coming out of the assembly gap, thereby ensuring the connection reliability of the insertion portion and the insertion slot; in addition, when the insertion portion of the second member is inserted into the insertion slot along the first direction Z during assembly, the limiting portion will be driven by the insertion portion along the first direction Z due to the force applied by the insertion portion along the first direction Z, thereby driving the compensation portion to be inserted into the insertion slot along the first direction Z, i.e., the assembly of the compensation sheet is completed at the same time as the insertion of the insertion portion into the insertion slot, thereby reducing the difficulty of inserting the compensation sheet, and the assembly of the first member, the compensation sheet and the second member can be completed without the aid of tools, thereby making the assembly of the connecting member more convenient, and ensuring the connection reliability of the first member and the second member and preventing the two from shaking, especially when the first direction Z is the direction of gravity, the gravity applied by the body to the second member and the gravity applied by the user to the second member through the body can make the compensation sheet always have an interference fit with the assembly gap, thereby further improving the connection reliability of the second member and the first member; finally, the material of the compensation sheet can be different from that of the first member and the second member, and since the interference is provided by the compensation portion, the compensation portion only needs to have a certain toughness at this time, so the material selection range of the first member and the second member can be more extensive.

[0007] In the above connecting member for furniture, the limiting portion comprises a limiting sheet arranged between the bottom of the insertion slot and the bottom of the insertion portion, one end of the compensation portion is connected to the limiting sheet, and the other end extends in the opposite direction of the first direction Z and extends into the assembly gap. By such design, the compensation sheet can be pre-assembled in the insertion slot or on the insertion portion, without limiting the assembly sequence of the compensation sheet, thus facilitating assembly, and further facilitating the later replacement of the compensation sheet.

[0008] In the above connecting member for furniture, the compensation sheet comprises two oppositely arranged compensation portions, and the limiting sheet is connected between the two compensation portions. By such design, the consistency of the insertion positions of the two insertion portions of the second member can be ensured, and the compensation sheet can be semi-enclosed outside the insertion portion, which not only improves the limiting effect of the limiting sheet on the insertion portion, but also allows the compensation sheet to be pre-wrapped outside the insertion portion and then inserted into the insertion slot together with the insertion portion, thereby further reducing the assembly difficulty of the connecting member.

[0009] In the above connecting member for furniture, the limiting sheet has a natural state of unfolding and a bent state of being bent, and the limiting sheet is semi-enclosed on the insertion portion when it is in the bent state. By such design, not only is the processing and molding of the limiting sheet in the natural state facilitated, but also the limiting sheet can be bent to match the shape of the bottom of the insertion portion during use, thereby improving the versatility of the compensation sheet.

[0010] In the above-mentioned furniture connecting member, the compensation sheet further comprises a crease portion having a natural state of unfolding and a bent state of folding, and the limiting sheet is connected to the compensation portion through the crease portion. In this way, the limiting sheet can be easily processed and packaged in the natural state, and the crease portion can be bent to match the shape of the connecting corner between the bottom and the side of the insertion portion (for the case that the cross-sectional shape of the insertion portion is rectangular) during use, thereby improving the versatility of the compensation sheet.

[0011] In the above-mentioned furniture connecting member, the thickness of the crease portion is smaller than the thickness of the limiting sheet and the compensation portion. In this way, the user can easily identify and bend the crease portion.

[0012] In the above-mentioned furniture connecting member, the limiting portion comprises a limiting boss protruding from one side of the compensation portion towards the insertion portion, and the insertion portion is provided with a limiting hole into which the limiting boss is inserted; and / or, the limiting portion comprises a limiting hole provided on the compensation portion, and the insertion portion is provided with a limiting boss inserted into the limiting hole. In this way, the limiting boss can be inserted into the limiting hole in advance, so that the compensation sheet is fixed on the insertion portion, and the compensation sheet is prevented from falling off during the subsequent insertion of the insertion portion into the insertion slot, thereby further reducing the assembly difficulty of the connecting member and facilitating the separate replacement of the compensation sheet in the later stage.

[0013] In the above-mentioned furniture connecting member, the limiting boss and the limiting hole are in interference fit. In this way, the compensation sheet can be prevented from shaking relative to the insertion portion, thereby ensuring the accuracy of the installation position of the compensation sheet.

[0014] In the above-mentioned furniture connecting member, the insertion portion drives the compensation portion to be inserted into the insertion slot through the limiting portion, and the interference amount between the compensation portion and the assembly gap increases with the increase of the insertion depth of the compensation portion. In this way, as the insertion portion is inserted deeper into the insertion slot, the interference amount between the compensation portion and the assembly gap gradually increases, i.e., the compensation portion and the insertion slot and the insertion portion are more and more tightly matched, thereby further improving the connection reliability of the insertion portion and the insertion slot, and avoiding the connection failure of the insertion portion and the insertion slot during use.

[0015] In the above-mentioned furniture connecting member, one of the side wall of the insertion slot and the side of the compensation portion away from the insertion portion 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 Z or the reverse direction. In this way, the protrusion and the groove can also be used to position the insertion position of the insertion portion, thereby ensuring the accuracy of the insertion position of the insertion portion; in addition, the protrusion or the groove structure is provided on the compensation portion, which can avoid processing on the insertion portion, thereby simplifying the processing technology of the second member.

[0016] In the connecting member for furniture, the protrusion has a first protruding surface facing away from the side surface, the groove has a first recessed surface in interference fit with the first protruding surface, and the interference amount between the first protruding surface and the first recessed surface increases with the increase of the insertion depth of the insertion part. In this way, when the first direction Z is the direction of gravity, the gravity of the body acting on the second member and the gravity of the user acting on the second member through the body can be used to make the insertion part insert deeper into the insertion slot, that is, the protrusion inserts deeper into the groove, the interference amount between the first protruding surface and the first recessed surface gradually increases, that is, the fitting between the compensation part and the insertion part and the insertion slot is more and more compact, thereby further improving the connection reliability of the insertion part and the insertion slot, and avoiding the connection failure of the insertion part and the insertion slot during use.

[0017] In the connecting member for furniture, the height of the first protruding surface protruding from the side surface gradually decreases along the first direction Z, and the recessed depth of the first recessed surface gradually decreases along the first direction Z. In this way, the machining difficulty of the first protruding surface and the first recessed surface can be simplified, and the machining and forming of the protrusion and the groove are facilitated.

[0018] In the connecting member for furniture, the protrusion has a second protruding surface connected between the first protruding surface and the side surface, the groove has a second recessed surface in interference fit with the second protruding surface, and the interference amount between the second protruding surface and the second recessed surface increases with the increase of the insertion depth of the insertion part. In this way, the fitting tightness of the protrusion and the groove can be further increased, and the connection reliability of the compensation part and the insertion slot is improved.

[0019] In the connecting member for furniture, the second member extends along a second direction, the first direction Z intersects the second direction, the insertion slot has a avoiding opening for avoiding the second member, and the protrusion and the groove are in fit to limit the insertion part in the second direction. In this way, the insertion part can be prevented from separating from the insertion slot along the second direction through the avoiding opening, and the connection reliability of the insertion part and the insertion slot is further improved.

[0020] In the connecting member for furniture, the side wall of the insertion slot is provided with a groove, the compensation part is inserted into the groove along the first direction, and the interference amount between the compensation part and the assembly gap increases with the increase of the insertion depth of the compensation part. In this way, the structure of the compensation part can be simplified, and the machining process of the compensation sheet is simplified.

[0052] Embodiment one

[0053] As shown in FIGS. 1-14, the furniture connecting member of the present embodiment comprises a first member 100, a second member 200, and a compensation piece 300, the first member 100 is provided with a slot 110, the second member 200 comprises a plug-in part 210, the plug-in part 210 is inserted into the slot 110 along the first direction Z and there is an assembly gap between the plug-in part 210 and the slot 110, the assembly gap is the gap between the slot side wall and the plug-in part 210, the compensation piece 300 comprises a compensation part 310 and a limiting part 320 connected together, the compensation part 310 is in interference fit with the assembly gap so as to fix the plug-in part 210 in the slot 110, and the limiting part 320 is limited in the slot 110 by the force applied by the plug-in part 210 along the first direction Z.

[0054] After the connecting member is assembled, the limiting part 320 is limited in the slot 110 by the force applied by the plug-in part 210 along the first direction Z, thereby preventing the limiting part 320 from coming out of the slot 110, i.e. preventing the compensation part 310 connected thereto from coming out of the assembly gap, thereby ensuring the connection reliability of the plug-in part 210 and the slot 110; in addition, when the plug-in part 210 of the second member 200 is inserted into the slot 110 along the first direction Z during assembly, the limiting part 320 will be driven by the plug-in part 210 along the first direction Z due to the force applied by the plug-in part 210 along the first direction Z, thereby driving the compensation part 310 to insert into the slot 110 along the first direction Z, i.e. the plug-in part 210 is inserted into the slot 110 at the same time as the assembly of the compensation piece 300 is completed, thereby reducing the insertion difficulty of the compensation piece 300, and the assembly of the first member 100, the compensation piece 300 and the second member 200 can be completed without the aid of tools, thereby making the assembly of the connecting member more convenient, and further ensuring the connection reliability of the first member 100 and the second member 200, avoiding the shaking of the two, especially when the first direction Z is the direction of gravity, the gravity applied by the body to the second member 200 and the gravity applied by the user to the second member 200 through the body can be used to make the compensation piece 300 always in interference fit with the assembly gap, thereby further improving the connection reliability of the second member 200 and the first member 100; finally, the material of the compensation piece 300 can be different from that of the first member 100 and the second member 200, since the interference amount is provided by the compensation part 310, at this time only the compensation part 310 needs to have a certain toughness, so that the material selection range of the first member 100 and the second member 200 can be more extensive, i.e. the first member 100 and the second member 200 can both select materials with relatively hard materials to increase the structural strength of the two.

[0055] Specifically, the limiting part 320 in the embodiment includes a limiting sheet 321, the insertion slot 110 has oppositely arranged slot opening and slot bottom, the insertion part 210 is inserted into the insertion slot 110 along the first direction Z through the slot opening, and the limiting sheet 321 is arranged between the slot bottom of the insertion slot and the bottom of the insertion part 210. One end of the compensation part 310 is connected with the limiting sheet 321, and the other end extends along the reverse direction of the first direction Z and is inserted into the assembly gap. In this way, the compensation sheet 300 can be pre-assembled in the insertion slot 110 or on the insertion part 210, and the assembly sequence of the compensation sheet 300 is not limited, so that the assembly is convenient. In addition, the compensation sheet 300 can be replaced individually in the later period.

[0056] Preferably, the number of compensation parts 310 is two, the two compensation parts 310 are oppositely arranged and located on opposite sides of the insertion part 210, and the limiting sheet 321 is connected between the two compensation parts 310. In this way, the consistency of the insertion and assembly positions of the insertion part 210 at both ends of the second member 200 can be ensured, the second member 200 can be prevented from tilting, the limiting effect of the insertion part 210 on the limiting sheet 321 can be improved, the compensation sheet 300 can be pre-wrapped outside the insertion part 210 in a U shape and then inserted into the insertion slot 110 together with the insertion part 210, and the assembly difficulty of the connecting member can be further reduced. In addition to convenient assembly, the compensation sheet 300 can be replaced individually in the later period.

[0057] It can be understood that in other embodiments of the application, the limiting sheet can also be pre-assembled in the insertion slot, and then the insertion part is inserted and the compensation sheet is half-wrapped outside the insertion part, and then the second member is pressed along the first direction Z to drive the compensation sheet to be inserted into the insertion slot.

[0058] The cross section of the second member 200 in the embodiment is rectangular. Due to the existence of machining errors, the sizes of the bottom corners of the second members 200 in the same batch are different. In order to adapt the compensation sheet 300 to the second members 200 with different cross-sectional sizes, the compensation sheet 300 in the embodiment further includes a crease part 330. The crease part 330 has a natural state of unfolding (as shown in FIG. 8) and a bent state of bending (as shown in FIG. 3). The limiting sheet 321 is connected with the compensation part 310 through the crease part 330. In this way, the natural state of the limiting sheet 321 is beneficial to the machining and forming of the compensation sheet 300 and the transportation and packaging of the compensation sheet 300. In addition, the crease part 330 can be bent into a matching shape according to the shape of the connecting corner between the bottom and the side of the insertion part 210 in use, so as to improve the versatility of the compensation sheet 300.

[0059] Preferably, the compensation sheet 300 in the embodiment is a flexible plastic piece, and the compensation sheet 300 is partially cut away from the side away from the plug-in part 210, so that the thickness of the crease part 330 is less than the thickness of the limiting sheet 321 and the thickness of the compensation part 310. In this way, the user can identify the crease part 330 to facilitate folding the crease part 330, and the folding of the crease part 330 is more labor-saving.

[0060] It can be understood that in other embodiments of the present application, the compensation sheet can also be a flexible metal piece.

[0061] It can be understood that in other embodiments of the present application, the compensation sheet can also be a fixed shape matching the cross-sectional shape of the plug-in part.

[0062] In addition, in the embodiment, the plug-in part 210 drives the compensation part 310 to be inserted into the insertion slot 110 through the limiting part 320, and the interference amount of the compensation part 310 with the assembly gap increases with the increase of the insertion depth of the compensation part 310. In this way, as the plug-in part 210 is inserted deeper into the insertion slot 110, the interference amount of the compensation part 310 with the assembly gap gradually increases, that is, the compensation part 310 and the insertion slot 110 and the plug-in part 210 are more and more compact, thereby further improving the connection reliability of the plug-in part 210 and the insertion slot 110, and avoiding the connection failure of the plug-in part 210 and the insertion slot 110 during use.

[0063] In order to ensure the accuracy of the plug-in position of the plug-in part 210, in the embodiment, the side of each compensation part 310 away from the plug-in part 210 is provided with a protrusion 400, both side walls of the slot 110 are provided with a groove 500 extending from the slot opening to the slot bottom, the protrusion 400 is inserted into the groove 500 along the first direction Z, the protrusion 400 has a first protruding surface 410 away from the side of the compensation part 310, the groove 500 has a first recessed surface 510 in interference fit with the first protruding surface 410, and the interference amount between the first protruding surface 410 and the first recessed surface 510 increases with the increase of the plug-in depth of the plug-in part 210. By such design, the positioning effect on the plug-in position of the plug-in part 210 can be achieved through the cooperation of the protrusion 400 and the groove 500, so as to ensure the accuracy of the plug-in position of the plug-in part 210. In addition, the protrusion 400 is arranged on the compensation part 310 and the groove 500 is arranged on the side wall of the slot, so that the machining on the plug-in part 210 can be avoided, thereby simplifying the machining process of the second member 200. In addition, when the first direction Z is the direction of gravity, the gravity of the body acting on the second member 200 and the gravity of the user acting on the second member 200 through the body can be used to make the plug-in part 210 smoothly and deeply inserted into the slot 110, so that the protrusion 400 is more deeply inserted into the groove 500, the interference amount between the first protruding surface 410 and the first recessed surface 510 gradually increases, that is, the cooperation between the compensation part 310 and the plug-in part 210 and the slot 110 becomes more and more compact, thereby further improving the connection reliability of the plug-in part 210 and the slot 110 and avoiding the connection failure of the plug-in part 210 and the slot 110 in use.
