Description

Technical Field

[0001] This utility model belongs to the field of folding furniture, and particularly relates to a folding hinge and furniture that uses the folding hinge in tables, beds, doors, windows, wardrobes, etc. Background Technology

[0002] Folding furniture, such as tables, beds, doors, windows, and wardrobes, uses folding hinges to connect the main body, allowing relative rotation between the bodies to achieve folding or unfolding. When folding furniture has two or more main bodies, each body is connected sequentially as one unit, with adjacent bodies connected by two connecting parts of the folding hinge. When folded, each body is stacked sequentially in a fan-like folding motion. However, this folding method prevents adjacent bodies from mutually restraining each other, allowing them to unfold at a certain angle, resulting in a less flat fold and hindering overall space arrangement. Furthermore, a significant gap remains between the two connecting parts of the folding hinge after folding, preventing the bodies from fully overlapping and occupying storage space along the length of the folded body, thus affecting the overall folding and storage effect. Utility Model Content

[0003] The purpose of this utility model is to provide a folding hinge that makes folding furniture less likely to unfold after folding and saves storage space in the length direction of the folding body.

[0004] The folding hinge includes a first mounting base, a connecting component, and a second mounting base. The first mounting base is connected to the second mounting base via the connecting component, enabling the first and second mounting bases to move relative to each other in a flat state and to rotate relative to each other from a flat state to a relative state.

[0005] The connecting assembly includes a first connecting piece and a second connecting piece. The two ends of the first connecting piece are rotatably connected to the first mounting base and the second mounting base, respectively, and the two ends of the second connecting piece are rotatably connected to the first mounting base and the second mounting base, respectively.

[0006] One end of the first connecting piece is slidably connected to the first mounting base, and one end of the second connecting piece is slidably connected to the second mounting base.

[0007] The other end of the first connecting piece is provided with a first limiting member for sliding and limiting the second connecting piece, and the other end of the second connecting piece is provided with a second limiting member for sliding and limiting the first connecting piece.

[0008] One end of the first connecting piece and one end of the second connecting piece are provided with a first bent plate. The first bent plate is rotatably connected by a sliding rod, and the sliding rod is slidably installed on the first mounting base and the second mounting base respectively.

[0009] Both the first limiting member and the second limiting member are barbs used to hook the sliding rod. The barbs are connected to the other end of the first connecting piece and the other end of the second connecting piece through the second bent plate. The second bent plate is rotatably connected by a pin, and the pin is installed on the first mounting base and the second mounting base.

[0010] A gasket is provided between the first connecting piece and the second connecting piece.

[0011] The pin and barb are both located below the slide bar, and the end height of the first bent plate is greater than the end height of the second bent plate.

[0012] Both the first mounting base and the second mounting base include a mounting plate and a receiving groove, and the first connecting piece and the second connecting piece...

[0013] The plates are installed along the receiving groove, which has mounting plates on both sides and sliding grooves along both sides.

[0014] The two ends of the slide rod are slidably installed in the slide groove.

[0015] The furniture includes the aforementioned folding hinges, and also includes at least two panels, with adjacent panels mounted via folding hinges.

[0016] The sheet material can be folded from the outside in and nested into a folded body.

[0017] The beneficial effects of this utility model are as follows: the first connecting piece and the second connecting piece are both rotatably connected at one end and slidably connected at the other end. By sliding the first connecting piece and the second connecting piece relative to or towards each other, the first mounting base and the second mounting base can be driven to move towards or away from each other in a flat state. When the first mounting base and the second mounting base move away from each other, the distance between the first mounting base and the second mounting base continuously increases, so that an installation distance for placing multiple layers of boards is formed between the first mounting base and the second mounting base. At the same time, when the first mounting base and the second mounting base rotate relative to each other to a relative state and fold, the first mounting base and the second mounting base are limited by hooks engaging the sliding rods, so that the boards corresponding to the first mounting base and the second mounting base are folded from the outside to the inside and nested in multiple layers, thereby saving storage space in the length direction of the folded body.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] like Figure 1 , 6 As shown in Figure 7, the folding hinge E includes a first mounting base 1, a connecting component, and a second mounting base 2. The first mounting base 1 and the second mounting base 2 have the same structure and both include a mounting plate 3 and a receiving groove 4. The two ends of the receiving groove 4 are through grooves. The mounting plates 3 extend from the top surfaces of both sides of the receiving groove 4 along the length direction of the receiving groove 4. The mounting plates 3 are provided with mounting holes 17 for mounting the furniture body. The mounting holes 17 are evenly distributed on the mounting plates 3. The two sides of the receiving groove 4 are provided with sliding grooves 5 along the length direction of the receiving groove 4. The two ends of the sliding grooves 5 are closed.

[0027] like Figure 1 , 2 As shown in Figures 3, 4, and 5, the connecting assembly consists of a first connecting piece 6 and a second connecting piece 7. There are two sets of both the first connecting piece 6 and the second connecting piece 7, each set consisting of three connecting pieces A completely stacked together. Each connecting piece A has the same structure and is integrally formed. One end of the connecting piece A has a first bent plate 8, which is rotatably connected via a sliding rod 9. The other end of the connecting piece A has a second bent plate 11, and the end of the second bent plate 11 has a barb 10, which serves as both a first and second limiting element. The second bent plate 11 is rotatably connected via a pin 12.

[0028] When the first mounting base 1 and the second mounting base 2 move towards each other and close together in a flush position, the first connecting piece 6 is located in the receiving groove 4 of the first mounting base 1, and the second connecting piece 7 is located in the receiving groove 4 of the second mounting base 2. A sliding rod 9 passes through the end of the first bent plate 8 of each connecting piece A of the two sets of first connecting pieces 6, and the two ends of the sliding rod 9 are slidably installed in the sliding groove 5 of the first mounting base 1; another sliding rod 9 passes through the end of the first bent plate 8 of each connecting piece A of the two sets of second connecting pieces 7, and the two ends of the sliding rod 9 are slidably installed in the sliding groove 5 of the second mounting base 2. A pin 12 passes through the connection between the second bent plate 11 and the barb 10 of each connecting piece A of the two sets of first connecting pieces 6, and the two ends of the pin 12 are fixed to both sides of the receiving groove 4 of the first mounting base 1; another pin 12 passes through the connection between the second bent plate 11 and the barb 10 of each connecting piece A of the two sets of second connecting pieces 7, and the two ends of the pin 12 are fixed to both sides of the receiving groove 4 of the second mounting base 2.

[0029] When the first mounting base 1 and the second mounting base 2 move in opposite directions while in a flush position, the two sets of first connecting pieces 6 and the two sets of second connecting pieces 7 are staggered in the width direction of the receiving groove 4. This causes one set of first connecting pieces 6 to slide between the two sets of second connecting pieces 7, and one set of second connecting pieces 7 to slide between the two sets of first connecting pieces 6. The connecting piece A on the outer side of the other set of first connecting pieces 6 slides along the inner wall of the receiving groove 4 of the first mounting base 1 and the second mounting base 2, and the connecting piece A on the outer side of the other set of second connecting pieces 7 slides along the inner wall of the receiving groove 4 of the first mounting base 1 and the second mounting base 2. Furthermore, since the beginning and end ends of each connecting piece A of the two sets of first connecting pieces 6 are reversed with the beginning and end ends of each connecting piece A of the two sets of second connecting pieces 7, and by setting the bending angle B of the first bending plate 8 to be greater than the bending angle B of the second bending plate 11, and the end height C of the first bending plate 8 to be greater than the end height C of the second bending plate 11, each pin 12 and each barb 10 are located below each sliding rod 9, thus avoiding interference between the connecting pieces A during the sliding process. In addition, a gasket D is welded to the root of the two outer connecting pieces A of the first connecting piece 6, and a gasket D is welded to the root of the inner connecting piece A of the other first connecting piece 6. By setting the gasket D, the first connecting piece 6 and the second connecting piece 7 are pressed and limited in the width direction of the receiving groove 4, so as to prevent the first connecting piece 6 and the second connecting piece 7 from swinging during the sliding process, thereby ensuring the smooth sliding of the connecting piece A.

[0030] like Figure 1 , 2As shown in 3, 4, 5, 6, and 7, the furniture, such as a table or bed, comprises three panels. Two adjacent panels are fixed by corresponding screws through the mounting holes 17 of the mounting plates 3 of the first mounting seat 1 and the second mounting seat 2 of the aforementioned folding hinge E. Each panel is folded from the outside in and nested into a folded body. Since each connecting piece A of the first connecting piece 6 and each connecting piece A of the second connecting piece 7 is connected by a second bent plate 11 at one end driving a barb 10 to rotate along the pin 12, and a first bent plate 8 at the other end rotating along a slide rod 9 and sliding along a slide groove 5, the first mounting seat 1 and the second mounting seat 2 move in opposite directions in a flat state, causing the first connecting piece 6 and the second connecting piece 7 to slide towards each other and fold together, thus creating a gap between the first mounting seat 1 and the second mounting seat 2. This gap forms a placement space. When the first mounting seat 1 and the second mounting seat 2 move in opposite directions until the slide rod 9 slides to the closed end of the slide groove 5 and is limited, the first mounting seat 1 and the second mounting seat 2 form the maximum gap, which forms the maximum placement space 16. At this time, the first mounting seat 1 and the second mounting seat 2 are rotated from the outside to the inside to a relative state and folded, and the barb 10 hooks the slide rod 9 to limit the first mounting seat 1 and the second mounting seat 2, thereby stacking the first plate 13 and the second plate 14. Similarly, by folding the first board 13 and the second board 14 in the same folding direction (from the outside in), the second board 14 and the third board 15 are also stacked on top of each other, and the third board 15 is placed exactly in the maximum placement space 16. This allows the first board 13, the second board 14, and the third board 15 to be tightly nested into a folded body, thereby saving storage space along the length of the folded body. By adjusting the length of the connecting piece A, the size of the maximum placement space 16 can be changed to accommodate multiple board thicknesses, thus achieving a multi-layer nested folding effect and expanding the application range of folding furniture.
