Description

Technical Field

[0001] This disclosure relates to the field of furniture, and in particular, to a connection structure for furniture. Background Technology

[0002] Some furniture, such as bed frames and shelves, has slender structural components. To reduce packaging volume, these components are often transported unassembled. As a connecting structure, one component can be arranged vertically, while another can be arranged horizontally. The former may have a protruding connecting part on one side, and the latter may have a matching connecting part at one end. The two connecting parts mate to connect the two components together. However, the protruding connecting part increases packaging volume, which is inconvenient for transportation. Summary of the Invention

[0003] In view of this, the present disclosure provides a connection structure and furniture to reduce the packaging volume of the connection structure.

[0004] The connection structure disclosed herein includes a first structural member, a movable seat, and a second structural member. The first structural member extends vertically. The movable seat is pivotally connected to the first structural member between a first position and a second position, and includes a first connecting portion. When the movable seat is in the first position, its length direction is substantially collinear with the vertical direction. When the movable seat is in the second position, its length direction is substantially perpendicular to the vertical direction, such that the first connecting portion protrudes from one side of the first structural member. The second structural member includes a second connecting portion. When the movable seat is in the second position, the second connecting portion is connected to the first connecting portion.

[0005] When in the first position, the length direction of the movable seat is substantially collinear with the vertical direction, and the first connecting part does not protrude from the side of the first structural member. When in the second position, the length direction of the movable seat is substantially perpendicular to the vertical direction, and the first connecting part protrudes from one side of the first structural member to connect with the second connecting part. In this way, during transportation, the movable seat can be placed in the first position to reduce packaging volume; and when assembling furniture, the pivoting movable seat can move from the first position to the second position, connecting the first and second structural members of the furniture.

[0006] Alternatively or supplementally, the first structural member is at least partially hollow, such that when the movable seat is in the first position, the movable seat is at least partially housed within the first structural member.

[0007] To reduce weight, the first structural component typically has a hollow structure. This hollow structure allows the first structural component to house at least a portion of the movable seat in the first position. This helps reduce the overall length of the first structural component and the movable seat when the movable seat is in the first position, and also helps protect the movable seat.

[0008] Traditional connection structures typically require fasteners, such as screws, to assemble the various structural components during installation. However, this method of connection presents challenges due to the complexity of the assembly process and necessitates additional tools for disassembling and assembling furniture.

[0009] In view of this, according to the connection structure provided in this disclosure, in some examples, one of the first connecting portion and the second connecting portion is provided with a protrusion and the other is provided with a slot, such that when the movable seat is in the second position, as the second connecting portion moves downward toward the first connecting portion, the slot receives the protrusion to connect the second connecting portion with the first connecting portion.

[0010] With this design, during assembly, the two structural components can be assembled simply by rotating the movable seat pivot to the second position and moving the second connecting part downwards toward the first connecting part so that the slot receives the protrusion. This assembly method is convenient and does not require additional tools.

[0011] Alternatively or supplementally, when the movable seat is in the second position and the slot receives the ridge, both the ridge and the slot are tilted relative to the vertical direction.

[0012] Both the ridge and the slot are inclined relative to the vertical direction, that is, the ridge and the slot form an angle with the length direction of the second structural member. This helps to distribute the force and reduce the force acting on the connection position of the ridge and the slot, so that the connection between the first connection part and the second connection part is not easy to loosen, especially when facing the vertical swing centered on the connection structure.

[0013] Alternatively or supplementally, both the ridge and the slot tend to slope downwards towards the first structural member.

[0014] Both the protrusion and the slot are inclined downwards towards the first structural member. Therefore, when connecting the first and second connecting parts, the second connecting part needs to approach the first structural member and be inserted downwards. As the second connecting part approaches the first structural member and is inserted downwards, on the one hand, the slot gradually receives the protrusion, and on the other hand, the gap between the second connecting part and the outer surface of the first structural member gradually decreases. When the protrusion is fully inserted into the slot, the end face of the second structural member abuts against the outer surface of the first structural member. This allows the outer surface of the first structural member and the protrusion or slot to form a clamping force on the second connecting part, thereby improving the stability of the connection structure.

[0015] Alternatively or supplementally, both the ridge and the slot form an angle of 75 to 85 degrees with the length direction of the movable seat.

[0016] Research has found that the convex strips and slots with this feature can more effectively prevent the first connecting part from loosening and further reduce the risk of the first connecting part and the second connecting part falling off.

[0017] Alternatively or supplementarily, the first connecting portion includes an insertion portion, which has protrusions on each side of the movable seat in the width direction. The second connecting portion includes a bottom-open receiving portion, which includes two side walls and a top wall. The side walls are spaced apart in the width direction, and the top wall extends between the upper ends of the side walls. Each side wall has a bottom-open slot. The insertion portion is inserted into the receiving portion such that the protrusions on each side of the insertion portion in the width direction are received by a slot of a corresponding side wall.

[0018] During assembly, the cooperation between the insertion part and the receiving part helps align the protrusions and slots, reducing assembly difficulty. Furthermore, the cooperation between the two side walls and the insertion part improves the connection structure's resistance to width-direction swaying, further enhancing connection strength. Additionally, the cooperation between the top wall and the insertion part improves the connection structure's resistance to vertical-direction swaying, further enhancing connection strength. Moreover, the insertion part has protrusions in the width direction, and the receiving part has slots on both side walls; the cooperation of multiple protrusions and slots further improves connection strength.

[0019] Alternatively or supplementarily, the first connecting portion includes an insertion portion having a slot open at its top. The second connecting portion includes a receiving portion open at its bottom, the receiving portion including two side walls spaced apart in the width direction of the movable seat, with protrusions extending between the side walls. The insertion portion is inserted into the receiving portion such that the protrusions are received by the slots respectively.

[0020] During assembly, the cooperation between the insert and the receiving part helps align the protrusion and the slot, reducing assembly difficulty. Furthermore, the cooperation between the two sidewalls and the insert improves the connection structure's resistance to width-direction sway, further enhancing connection strength. Additionally, after inserting the insert into the receiving part, the protrusion and slot are concealed, contributing to a more aesthetically pleasing connection structure.

[0021] Alternatively or supplementally, the movable seat includes a seat frame with an upwardly open U-shaped cross section and a seat plug inserted into the seat frame, the slot being defined by the seat frame and the seat plug, the seat frame being made of metal and the seat plug being made of plastic.

[0022] Metal materials offer higher strength but are heavier and more expensive, while plastic materials are lighter and cheaper but less strong. A movable seat composed of a U-shaped metal frame and a plastic insert achieves a balance of high strength, light weight, and low cost.

[0023] Alternatively or supplementally, the connecting structure also includes a pivot shaft mounted on the first structural member, and the movable seat having a bore through which the pivot shaft passes. The bore is larger in the length direction of the movable seat than the diameter of the pivot shaft, to allow the movable seat to slide relative to the pivot shaft along the length direction to and from the pivot center.

[0024] When the movable seat slides relative to the pivot axis to the pivot center, the movable seat can pivot around the pivot center and switch between the first position and the second position. When the movable seat pivots around the pivot center to the first position, the movable seat will slide relative to the pivot axis and leave the pivot center under the action of gravity. At this time, the pivoting of the movable seat will be restricted and it will be kept in the first position.

[0025] The furniture disclosed herein includes the aforementioned connection structure. Attached Figure Description

[0040] The embodiments of this disclosure are described below with reference to the accompanying drawings. It should be understood that there are various implementations of this disclosure, and it should not be construed as being limited to the embodiments set forth herein. The embodiments set forth herein are merely for a more thorough and clear understanding of this disclosure.

[0041] This disclosure provides a piece of furniture 200. For example, furniture 200 can be a bed frame. Of course, furniture 200 is not limited to a bed frame; it can also be other types of furniture, such as a storage shelf. (See reference) Figure 1 Furniture 200 may include a first structural member 10 and a second structural member 20, which can be assembled together by a connecting structure 100.

[0042] refer to Figure 2 The connecting structure 100 may include a first structural member 10, a movable seat 30, and a second structural member 20. The first structural member 10 extends in a vertical direction. The movable seat 30 is pivotally connected to the first structural member 10 between a first position and a second position, and includes a first connecting portion 31. When the movable seat 30 is in the first position, its length direction is substantially collinear with the vertical direction. When the movable seat 30 is in the second position, its length direction is substantially perpendicular to the vertical direction, such that the first connecting portion 31 protrudes from one side of the first structural member 10. The second structural member 20 includes a second connecting portion 21, wherein when the movable seat 30 is in the second position, the second connecting portion 21 is connected to the first connecting portion 31.

[0043] When in the first position, the length direction of the movable seat 30 is substantially collinear with the vertical direction, and the first connecting portion 31 does not protrude from the side of the first structural member 10. When in the second position, the length direction of the movable seat 30 is substantially perpendicular to the vertical direction, and the first connecting portion 31 protrudes from one side of the first structural member 10 to connect with the second connecting portion 21. In this way, during transportation, the movable seat 30 can be placed in the first position to reduce the overall packaging volume; while when assembling the furniture 200, the movable seat 30 is pivoted from the first position to the second position, connecting the first structural member 10 and the second structural member 20 of the furniture 200.

[0044] It is understood that in this disclosure, directional descriptions such as "up," "down," "front," "back," "left," and "right" are relative rather than absolute. These directional descriptions apply when the elements in this disclosure are in the placement posture and position shown in the figure, or in the placement posture and position used in daily life. For example, when using furniture 200 in daily life, the up and down direction in this document can be parallel to the direction of gravity.

[0045] For ease of understanding, in the accompanying drawings of this disclosure, arrow Z+ can be used to indicate the upper side in the vertical direction, and arrow Z- can be used to indicate the lower side in the vertical direction; arrows X+ and X- can be used to indicate opposite sides of a first direction orthogonal to the vertical direction; arrows Y+ and Y- can be used to indicate opposite sides of a second direction orthogonal to both the vertical direction and the first direction. When the movable seat 30 is in the first position, the movable seat 30 uses the vertical direction as its length direction; when the movable seat 30 is in the second position, the movable seat 30 uses the first direction as its length direction. These elements, such as the first structural member 10, the second structural member 20, and the movable seat 30, can all use the second direction as their width direction, regardless of the position of the movable seat 30.

[0046] refer to Figure 3 The first structural member 10 is at least partially hollow, such that when the movable seat 30 is in the first position, the movable seat 30 is at least partially housed within the first structural member 10. To reduce weight, the first structural member 10 typically has a hollow structure. This hollow structure of the first structural member 10 allows it to house at least a portion of the movable seat 30 in the first position, which helps reduce the overall length of the first structural member 10 and the movable seat 30 when the movable seat 30 is in the first position, and also helps protect the movable seat 30.

[0047] During installation, fasteners, such as screws, are typically used to assemble the various structural components. However, this method of connection presents the problem of complex assembly operations and requires additional tools when disassembling and assembling furniture.

[0048] In view of this, refer to Figure 2 and Figure 3According to the connection structure 100 provided in this disclosure, the first connecting portion 31 may be provided with a protrusion 312, and the second connecting portion 21 may be provided with a slot 223, such that when the movable seat 30 is in the second position, as the second connecting portion 21 moves downward toward the first connecting portion 31, the slot 223 receives the protrusion 312 to connect the second connecting portion 21 to the first connecting portion 31. With this configuration, during assembly, it is only necessary to pivot the movable seat 30 to the second position and move the second connecting portion 21 downward toward the first connecting portion 31 so that the slot 223 receives the protrusion 312 to assemble the two structural components together. This assembly method is convenient to operate and does not rely on additional tools.

[0049] It is understood that there can be multiple ridges and slots, and this disclosure does not impose any particular limitation on this.

[0050] Continue to refer to Figure 2 and Figure 3 When the movable seat 30 is in the second position and the slot 223 receives the protrusion 312, both the protrusion 312 and the slot 223 are inclined relative to the vertical direction. The protrusion 312 and the slot 223 form an angle α with the length direction of the movable seat 30. This helps to distribute the force and reduce the force acting at the connection position of the protrusion 312 and the slot 223, thereby making the connection between the first connecting part 31 and the second connecting part 21 less prone to loosening, especially when facing vertical swinging centered on the connection structure.

[0051] Continue to refer to Figure 2 and Figure 3 Both the protrusion 312 and the slot 223 are inclined downwards towards the first structural member 10. Therefore, when connecting the first connecting portion 31 and the second connecting portion 21, the second connecting portion 21 needs to approach the first structural member 10 and be inserted downwards. As the second connecting portion 21 approaches the first structural member 10 and is inserted downwards, on the one hand, the slot 223 gradually receives the protrusion 312; on the other hand, the gap between the second connecting portion 21 and the outer surface of the first structural member 10 gradually decreases. When the protrusion 312 is fully inserted into the slot 223, the end face of the second structural member 20 abuts against the outer surface of the first structural member 10. This allows the outer surface of the first structural member 10 and the protrusion 312 to form a clamping force on the second connecting portion 21, thereby improving the stability of the connecting structure 100.

[0052] Continue to refer to Figure 2 Both the protrusion 312 and the slot 223 form an angle α with the length direction of the movable seat 30. Studies have found that when α is between 75 and 85 degrees, the protrusion 312 and the slot 223 can more effectively prevent the first connecting part 31 and the second connecting part 21 from loosening, further reducing the risk of the first connecting part 31 and the second connecting part 21 falling off.

[0053] Continue to refer to Figure 2 and Figure 3 The first connecting portion 31 includes an insertion portion 311, which has protrusions 312 on each side of the movable seat 30 in the width direction. The second connecting portion 21 includes a receiving portion 22 with an open bottom, which includes two side walls 221 and a top wall 222. The side walls 221 are spaced apart in the width direction, and the top wall 222 extends between the upper ends of the side walls 221. Each side wall 221 has a slot 223 with an open bottom. The insertion portion 311 is inserted into the receiving portion 22, such that the protrusions 312 on each side of the insertion portion 311 in the width direction are received by a slot 223 of a corresponding side wall 221. The insertion portion 311 has a plurality of protrusions 312 spaced apart in the length direction on each side in the width direction.

[0054] During assembly, the cooperation between the insertion part 311 and the receiving part 22 helps align the protrusions 312 and the slots 223, reducing assembly difficulty. Furthermore, the cooperation between the two side walls 221 and the insertion part 311 enhances the connection structure 100's resistance to width-direction swaying, further improving connection strength. Additionally, the cooperation between the top wall 222 and the insertion part 311 enhances the connection structure 100's resistance to vertical-direction swaying, further improving connection strength. Moreover, the insertion part 311 has protrusions 312 in the width direction, and the receiving part 22 has slots 223 on both side walls 221; the cooperation of multiple protrusions 312 and multiple slots 223 further improves connection strength.

[0055] In order to be housed within the first structural member 10, the shape of the movable seat 30 should be adapted to the dimensions of the hollow structure of the first structural member 10. As an example, refer to... Figure 4 The first structural member 10 includes an opening 11 that opens toward the second structural member 20. The opening 11 may include a narrow opening 111 and a wide opening 112. The width of the narrow opening 111 is B1, and the width of the wide opening 112 is B2. The width of the insertion portion 311 is A1, and the maximum spacing between the protrusions 312 on both sides of the insertion portion 311 in its width direction is A2.

[0056] The shape parameters of the opening 11 and the movable seat 30 should satisfy B1 being greater than A1, so that when the movable seat 30 is in the second position, the insertion part 311 can be located outside the first structural member 10.

[0057] The shape parameters of the opening 11 and the movable seat 30 should also satisfy that B2 is greater than A2, so that when the movable seat 30 is in the first position, the insertion part 311 can be smoothly housed in the first structural member 10.

[0058] Back Figure 3The connecting structure 100 may further include a pivot shaft 41 mounted on the first structural member 10, and the movable seat 30 is provided with a shaft hole 32 through which the pivot shaft 41 passes. The dimension of the shaft hole 32 in the length direction of the movable seat 30 is larger than the diameter of the pivot shaft 41, so as to allow the movable seat 30 to slide relative to the pivot shaft 41 in the length direction to and from the pivot center.

[0059] When the movable seat 30 slides relative to the pivot axis 41 to the pivot center, the movable seat 30 can pivot around the pivot center, switching between a first position and a second position. (Reference) Figure 5A When the movable seat 30 pivots about the pivot center to the second position, the movable seat 30 can connect the first structural member 10 and the second structural member 20, at which time the pivot shaft 41 is located at the pivot center. When the movable seat 30 pivots about the pivot center to the first position (i.e., from the pivot center to the second position), the movable seat 30 can connect the first structural member 10 and the second structural member 20. Figure 5A The position shown has changed to Figure 5B (as shown in the image) Under the influence of gravity, the movable seat 30 will slide relative to the pivot axis 41 and move away from the pivot center (i.e., from the position shown in the image). Figure 5A The location shown is via Figure 5B Change to Figure 5C (as shown in the position), at this time, the pivoting of the movable seat 30 will be restricted and it will be held in the first position.

[0060] refer to Figures 5A to 5C Since the movable seat 30 can be fully received by the first structural member 10, the top of the first structural member 10 can be completely closed to improve structural strength. Of course, in some examples, the completely closed top of the first structural member 10 can also be used for load-bearing.

[0061] Continue to refer to Figure 5A The movable seat 30 can extend upwards with a raised rib 33. Combined with... Figure 5B and Figure 5C When the movable seat 30 pivots around the pivot center to the first position, the protruding rib 33 can first contact the inner wall of the first structural member 10, thereby restricting the pivoting of the movable seat 30 and keeping the movable seat 30 in the first position.

[0062] Continue to refer to Figure 5C When the movable seat 30 slides away from the pivot center relative to the pivot axis 41, the inner surface of the first structural member 10 can restrict the pivoting of the movable seat 30, so that the movable seat 30 remains in the first position. For example, after leaving the pivot center, the movable seat 30a is restricted by the edge of the opening 11 and is held in the first position.

[0063] It should be understood that there are various ways to implement the connection structure of this disclosure, and it should not be construed as being limited to the embodiments described above. The following, in conjunction with... Figures 6 to 9 , Figures 10A to 10CThe following are illustrative examples of variations of this disclosure. It should be noted that the foregoing embodiments and the following variations share some common elements. In the following variations, these elements will use the same reference numerals as in the foregoing embodiments to omit repeated descriptions.

[0064] refer to Figures 6 to 8 In the connecting structure 100a, the first connecting portion 31a may be provided with a slot 311a that is open at the top. Figure 9 The second connecting portion 21a includes a receiving portion 22a with an open bottom. The receiving portion 22a includes two side walls 221a spaced apart in the width direction of the movable seat 30a, and a protrusion 223a extends between the two side walls 221a. The insertion portion 311a is inserted into the receiving portion 22a, such that the protrusion 223a is received by the slot 311a.

[0065] During assembly, the cooperation between the insertion part 311a and the receiving part 22a helps align the protrusion 223a and the slot 312a, reducing assembly difficulty. Furthermore, the cooperation between the two sidewalls and the insertion part 311a enhances the connection structure 100a's resistance to swaying in the width direction, further improving connection strength. Additionally, after inserting the insertion part 311a into the receiving part 22a, both the protrusion 223a and the slot 312a are concealed, contributing to improved aesthetics of the connection structure 100a.

[0066] refer to Figure 7 and Figure 8 The movable seat 30a may include a seat frame 33 with an upwardly opening U-shaped cross-section and a seat plug 34 inserted into the seat frame 33. The slot is defined by the seat frame 33 and the seat plug 34. The seat frame 33 is made of metal, and the seat plug 34 is made of plastic. The seat plug 34, located on the U-shaped cross-section seat frame 33, ensures sufficient strength for the movable seat 30a. Furthermore, the seat plug 34 is made of plastic, which saves on production costs and reduces the overall weight of the movable seat 30a. Metal materials have higher strength but are heavier and more expensive, while plastic materials are lighter and less expensive but have lower strength. The movable seat 30a, composed of a U-shaped cross-section metal seat frame 33 and a plastic seat plug 34, achieves both high strength and a lighter weight and lower cost.

[0067] refer to Figure 7 and Figure 8 The connecting structure 100a may further include a pivot shaft 41 mounted on the first structural member 10, and the movable seat 30a is provided with a shaft hole 32a through which the pivot shaft 41 passes. The dimension of the shaft hole 32a in the length direction of the movable seat 30a is larger than the diameter of the pivot shaft 41, so as to allow the movable seat 30a to slide relative to the pivot shaft 41 in the length direction to and from the pivot center.

[0068] When the movable seat 30a slides relative to the pivot axis 41 to the pivot center, the movable seat 30a can pivot around the pivot center, switching between a first position and a second position. (Reference) Figure 10A When the movable seat 30a pivots around the pivot center to the second position, the movable seat 30a can connect the first structural member 10a and the second structural member 20a, at which time the pivot shaft 41 is located at the pivot center. When the movable seat 30a pivots around the pivot center to the first position (i.e., from the pivot center to the second position), the movable seat 30a can connect the first structural member 10a and the second structural member 20a. Figure 10A The position shown has changed to Figure 10B (as shown in the image) Under the influence of gravity, the movable seat 30a will slide relative to the pivot axis 41 and move away from the pivot center (i.e., from the position shown in the image). Figure 10B The position shown has changed to Figure 10C (As shown in the figure), at this position, the pivoting of the movable seat 30a will be restricted and held in the first position. For example, after leaving the pivot center, the movable seat 30a is restricted by the edge of the opening 11a and held in the first position. The opening 11a is described below.

[0069] refer to Figure 7 The first structural member 10a includes an opening 11a that opens toward the second structural member 20a. Combined Figure 10A and Figure 10B The opening 11a includes a first opening 111a and a second opening 112a. The first opening 111a opens along the length of the first structural member 10a, and the second opening 112a opens towards the second structural member 20 along the length of the movable seat 30a. Due to the avoidance of the first opening 111a, when the movable seat 30a pivots around the pivot center to the first position, the length of the movable seat 30a can be substantially collinear with the vertical direction. (Refer to...) Figure 10B Subsequently, under the influence of gravity, the movable seat 30a will slide relative to the pivot axis 41 and move away from the pivot center (i.e., from...). Figure 10B The position shown has changed to Figure 10C As shown in the position, the movable seat 30a can be received more by the first structural member 10a, which helps to reduce the overall length of the first structural member 10a and the movable seat 30a when the movable seat is in the first position, and also helps to protect the movable seat 30a.

[0070] refer to Figure 10A and Figure 10B The width A3 of the movable seat 30a is approximately equal to the width B3 of the first opening 111a. In this manner, when the movable seat 30a is in the first position, one side of the movable seat 30a can abut against the inner surface of the first structural member 10a, thereby restricting the pivoting of the movable seat 30.

[0071] refer to Figure 10B and Figure 10CWhen in the first position, at least a portion of the movable seat 30a is exposed outside the first structural member 10a. Therefore, the length of the first structural member 10a can be constructed to be shorter while ensuring that the movable seat 30a can be fixed, which helps to reduce the overall length of the connecting structure 100a. As an example, refer to... Figure 10C The top surface of the first structural member 10a can be located at any position between the top surface of the pivot shaft 41 and the top surface of the movable seat 30.

[0072] It should be understood that although terms such as “first” or “second” may be used in this disclosure to describe various elements, these elements are not defined by these terms, which are only used to distinguish one element from another.
