Description

Technical Field

[0001] This utility model relates to the technical field of furniture accessories, and more specifically to a fabric edge-sealing fastener and a cushion frame with edge-sealing capability. Background Technology

[0002] In everyday chairs, to enhance comfort, the seat cushion frame is filled with soft materials such as sponge or molded cotton. Then, a layer of mesh or other fabric is wrapped over the filling, and the edges of the outer fabric are secured to the seat cushion frame for finishing. Currently, seat cushion fabric finishing primarily uses brad nails to fix the edges of the fabric to the wooden board of the seat cushion frame. The finishing effect of brad nails heavily depends on the individual skill of the operator, making it difficult to standardize. Product quality is often inconsistent, and the brad nails are easily exposed, affecting the aesthetics of the chair, reducing product quality, and also posing a risk of worker injury when using brad nails. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a fabric edge-finishing fastener that can optimize the edge-finishing process of cushion fabric, so as to standardize the manufactured cushions and improve product quality safely and efficiently.

[0004] The technical solution of this utility model is to provide a fabric edge-gathering fastener, including a fastener body in the shape of an elongated strip. The fastener body includes a first clamping part and a second clamping part that extend along the length direction and are arranged opposite to each other. The upper part of the first clamping part and the upper part of the second clamping part are movably connected. One of the first clamping part and the second clamping part is provided with a fabric locking buckle head, and the other part is provided with a fabric locking groove. The fabric locking buckle head is used to snap and lock with the fabric locking groove so that the first clamping part and the second clamping part are clamped together. The outer wall of the second clamping part is provided with a first assembly part that extends along the length direction. The first assembly part is used for external assembly.

[0005] Compared with the prior art, the fabric edge-finishing fastener of this utility model has the following advantages: the edge of the cut fabric used to wrap the cushion can be tucked between the first clamp and the second clamp, and then the fabric locking buckle head and the fabric locking slot can be locked to finish the edge of the cushion fabric; compared with the traditional nail gun finishing method, the application of the fabric edge-finishing fastener of this utility model can optimize the edge-finishing process of the cushion fabric, standardize the manufactured cushions, and thus improve product quality safely and efficiently.

[0006] Preferably, the sidewalls of the first and second clamping parts are respectively provided with toothed surfaces. The toothed surfaces on the first and second clamping parts can interlock to form a fabric interlocking area, which is located above the locking position of the fabric locking buckle and the fabric locking slot. This structure, by providing the fabric interlocking area, can greatly increase the clamping area and clamping force of the fabric edge-gathering fastener of this invention, preventing the fabric from slipping and detaching from the fabric edge-gathering fastener when pulled.

[0007] Preferably, a fabric edge receiving groove is provided between the first clamping part and / or the second clamping part. The fabric edge receiving groove extends along the length direction of the fastener body and is located at the connection where the first clamping part and the second clamping part are clamped. With this structure, the edge of the fabric can be rolled up or stacked several times, leaving some excess, and then inserted into the fabric edge receiving groove. In this way, the edge of the fabric is limited above the clamping part of the first clamping part and the second clamping part, and cannot pass through the clamping part, thus preventing the fabric from slipping when stretched.

[0008] Preferably, the first clamp and the second clamp are integrally molded. This structure allows for injection molding with PP plastic, facilitating production, and both the first and second clamps are elastic, resulting in a natural elastic connection at the top after molding.

[0009] Another technical problem that this utility model aims to solve is to provide a seat cushion frame with a roll-up edge, which can optimize the roll-up process of the seat cushion fabric, standardize the manufactured seat cushions, and improve product quality safely and efficiently.

[0010] The technical solution of this utility model is to provide a seat cushion frame with a foldable edge, including a seat cushion frame and a fabric folding fastener as described above, wherein the fabric folding fastener is connected to the outer side wall of the seat cushion frame through the first assembly part.

[0011] Compared with the prior art, the seat cushion frame of this utility model with foldable edges has the following advantages: the seat cushion frame and the fabric folding fastener can be manufactured separately, and then the fabric folding fastener is connected to the outer side wall of the seat cushion frame. This optimizes the process of folding the seat cushion fabric, standardizes the manufactured seat cushion, improves product quality safely and efficiently, and greatly reduces the manufacturing difficulty of the seat cushion frame.

[0012] Preferably, the first assembly part is an assembly slot, and an assembly buckle is provided on the outer wall of the seat cushion frame, which is snapped into the assembly slot. This structure simplifies the assembly process of connecting the fabric edge fastener to the outer wall of the seat cushion frame.

[0013] Preferably, the assembly buckle has a buckle groove in the middle, which divides the assembly buckle into two opposing buckle hooks. The assembly groove has two hook-limiting surfaces that correspond to and engage with the two buckle hooks respectively. With this structure, when the assembly buckle is engaged with the assembly groove, the buckle hooks can deform into the buckle groove, reducing assembly resistance. The hook-limiting surfaces limit the buckle hooks, ensuring a reliable connection between the fabric hem fastener and the seat cushion frame.

[0014] Preferably, the first assembly part is an assembly slot, and the outer wall of the seat cushion frame can be embedded in the assembly slot and has an interference fit with the assembly slot. Using this structure, the assembly work of connecting the fabric edge fastener to the outer wall of the seat cushion frame is simple and easy to operate.

[0015] Preferably, the inner side of the seat cushion frame has a seat filling area for assembling the pressure plate of the seat cushion, and the bottom of the seat filling area has a seat connecting part with several seat connecting holes for connecting screws. This structure facilitates the assembly of the seat cushion's pressure plate, such as a thick wooden board, within the seat cushion frame. After assembly, the pressure plate can be connected to the seat connecting part with screws.

[0016] Preferably, the top of the seat cushion frame is provided with a cover plate step surface, and a cover plate is provided on the cover plate step surface. The cover plate is used to hold the soft filling material of the seat cushion. With this structure, it is convenient to fill the seat cushion frame with soft filling material, and then cover it with fabric, and then tuck the covered fabric into the fabric edge-sealing fastener for edge sealing.

[0026] like Figure 3 As shown in the figure, the retractable seat cushion frame of this embodiment includes a seat cushion frame 2 and a fabric retraction fastener 1. The fabric retraction fastener 1 is as follows: Figure 1 As shown, it is long and narrow, including a first clamp 1-6 and a second clamp 1-7 that extend along the length direction and are arranged opposite to each other. The upper part of the first clamp 1-6 and the upper part of the second clamp 1-7 are movably connected. Specifically, the fabric edge fastener 1 is integrally injection molded from PP plastic, and the upper parts of the first clamp 1-6 and the second clamp 1-7 are connected and elastic.

[0027] Both the first clamping part 1-6 and the second clamping part 1-7 are provided with fabric edge receiving grooves 1-1. The fabric edge receiving grooves 1-1 on the first clamping part 1-6 and the fabric edge receiving grooves 1-1 on the second clamping part 1-7 extend along the length direction of the fabric edge fastener 1 and are opposite to each other on the left and right, and are located below the elastic connection position of the first clamping part 1-6 and the second clamping part 1-7.

[0028] The sidewalls of the first clamping part 1-6 and the second clamping part 1-7 opposite each other are provided with toothed surfaces below the fabric edge receiving groove 1-1. The toothed surfaces on the first clamping part 1-6 and the toothed surfaces on the second clamping part 1-7 can interlock to form the fabric interlocking area 1-2.

[0029] A fabric locking buckle 1-4 is provided on one of the first clamping part 1-6 or the second clamping part 1-7, and a fabric locking groove 1-3 is provided on the other. Specifically, in this embodiment, the first clamping part 1-6 is provided with a fabric locking buckle 1-4 below the fabric engagement area 1-2, and the second clamping part 1-7 is provided with a fabric locking groove 1-3 below the fabric engagement area 1-2. The fabric locking buckle 1-4 can be snapped into and locked with the fabric locking groove 1-3.

[0030] When the fabric locking buckle 1-4 is locked with the fabric locking slot 1-3, the first clamp 1-6 and the second clamp 1-7 are clamped together, the teeth of the fabric biting area 1-2 bite each other, and the fabric edge receiving groove 1-1 on the first clamp 1-6 and the fabric edge receiving groove 1-1 on the second clamp 1-7 are joined together to form a hole.

[0031] The outer wall of the second clamping part 1-7, i.e. the inner wall of the fabric edge fastener 1, is provided with an assembly slot 1-5. The assembly slot 1-5 extends along the length direction and is provided with two upper and lower hook limiting surfaces 1-51.

[0032] Seat cushion frame 2 Figure 2 As shown, the seat frame 2 is ring-shaped and has a mounting buckle 2-1 on its outer side wall. The mounting buckle 2-1 has a buckle groove 2-12 in the middle, which divides the mounting buckle 2-1 into two opposing buckle hooks 2-11.

[0033] like Figure 4 and Figure 5 As shown, the fabric edge fastener 1 is connected to the outer wall of the seat cushion frame 2 via a snap-fit ​​connection between the assembly buckle 2-1 and the assembly slot 1-5. When the assembly buckle 2-1 is snap-fitted to the assembly slot 1-5, the buckle hook 2-11 can deform into the buckle slot 2-12 to reduce assembly resistance until the hook limiting surface 1-51 limits the buckle hook 2-11. After assembly, the rebound force of the buckle hook 2-11 locks the hook limiting surface 1-51 and the buckle hook 2-11, achieving the limiting and ensuring a reliable connection between the fabric edge fastener and the seat cushion frame 2. Since the fabric edge fastener 1 is made of PP plastic, it is elastic and can be bent at the corner of the seat cushion frame 2. In this embodiment, a notch is made on the fabric edge fastener 1 at the corner connecting to the seat cushion frame 2 to improve the fit between the fabric edge fastener 1 and the seat cushion frame 2.

[0034] The inner side of the seat cushion frame 2 has a seat filling area 2-2 for assembling the pressure plate of the seat cushion. The bottom of the seat filling area 2-2 has a seat connecting part 2-3, which has several seat connecting holes 2-4 for connecting screws. The pressure plate of the seat cushion is generally a wood board or composite board of a certain thickness. After being installed in the seat filling area 2-2, the pressure plate can be connected to the seat connecting part 2-3 using screws.

[0035] The top of the seat cushion frame 2 is provided with a cover plate step surface 2-5, and a cover plate 3 is provided on the cover plate step surface 2-5. The cover plate 3 is used to support the soft filling of the seat cushion. After the soft filling is filled on the cover plate 3, fabric can be covered, and the covered fabric can be tucked into the fabric edge fastener 1 for edge finishing.

[0036] This utility model's retractable seat cushion frame optimizes the seat cushion fabric retraction process, making the manufactured seat cushions standardized and improving product quality safely and efficiently.

[0037] In other embodiments, the connection structure between the fabric edge fastener 1 and the outer side wall of the seat frame 2 may differ from that in Embodiment 1. For example, the inner side wall of the fabric edge fastener 1 may be provided with an assembly slot extending along the length direction, and the outer side wall of the seat frame 2 may match the assembly slot structure, that is, the outer side wall of the seat frame 2 may be embedded in the assembly slot and have an interference fit with the assembly slot.

[0038] In other embodiments, the first clamping part 1-6 and the second clamping part 1-7 of the fabric edge fastener 1 can be manufactured separately and connected by a hinge so that when the fabric locking buckle head 1-4 is locked with the fabric locking slot 1-3, the first clamping part 1-6 and the second clamping part 1-7 can still be clamped.

[0039] The above are merely specific embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Any modifications or equivalent substitutions to this utility model without departing from its spirit and scope should be covered within the protection scope of the claims of this utility model.
