Description

Technical Field

[0001] The utility model relates to the field of furniture, in particular to a cover structure used for furniture assembly. Background Art

[0002] Furniture is usually provided with a cover covering the supporting parts. In order to make the chair back or seat resistant to dirt, traditional chairs will pre-cover the chair back or seat with a cover with an opening. The cover is usually divided into two halves, and each half of the cover has a zipper. When covering the cover, the zipper is engaged and the opening of the cover is closed, and the cover is covered on the chair back or seat, and then the chair back or seat covered by the cover is installed on the seat.

[0003] However, such a structure is more troublesome when removing and washing the cover. Taking the seat as an example, the seat support member used to support the seat is usually located at the lower end of the seat. After the seat support member is connected and fixed to the seat, if you want to remove the entire cover, you can only remove the entire seat first. This method of removing and washing the cover is unrealistic and too difficult. Therefore, when the seat is installed and the cover needs to be removed, the cover can usually only be removed halfway, resulting in a situation where half is removed and washed and the other half is not. In addition to incomplete removal and washing, it will also affect the appearance of the seat.

[0004] In order to avoid the above problems, some seats will pre-install half of the zipper on the seat and the other half on the outer cover. For example, in the seat cushion cover patent with announcement number CN205548143, a first half zipper is provided on the bottom periphery of the body, and a second half zipper is provided on the periphery of the cover, so that the zipper can be engaged or disengaged to make the cover and the body detachably connected; wherein the seat cushion body has a plastic shell, the periphery of the plastic shell is wrapped with a hard edge strip, and the first half zipper is sandwiched between the two, and the first half zipper is reinforced by sewing threads, and the sewing threads are passed through the plastic shell, the hard edge strip and the first half zipper; although this structure will not cause the situation that half of the outer cover is disassembled and washed and the other half is not disassembled and washed, it is necessary to pass the sewing threads through the plastic shell and the hard edge strip of the hard material during processing, and the difficulty of sewing operation and processing will increase, and the corresponding processing cost will also increase; and if the seat cushion is a metal or wooden board with higher hardness, it is difficult for the sewing needle to penetrate the seat cushion, and the problem of difficulty in sewing processing will occur.

DETAILED DESCRIPTION

[0046] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0047] In the description of the present invention, the term "at least one" refers to one or more than one, unless otherwise clearly defined. The terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0048] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0049] The utility model has multiple implementation modes, and the specific implementation modes are as follows:

[0050] Example 1: Figure 1-6 As shown, the utility model provides a cover structure for furniture assembly, comprising:

[0051] The support assembly comprises a support member 1 and an edge banding strip 2 . The edge banding strip 2 surrounds and is connected and fixed on the outer periphery of the support member 1 .

[0052] The outer cover 6 is usually made of durable cloth or leather; it comprises a main body 61 for the mask support 1, and the main body 61 has a connection periphery 62 surrounding its closing position.

[0053] The zipper assembly includes a first zipper 3 and a second zipper 5 that can mesh with each other, one of the first zipper 3 and the second zipper 5 is connected to a lock head 33, and the second zipper 5 is pre-connected to the connecting periphery 62, so that the second zipper 5 and the jacket 6 form a whole, and the two cannot be separated; the first zipper 3 is pre-connected to the edge strip 2, and during batch processing, the first zipper 3 is connected to the edge strip 2 in a preset manner to form a large number of edge strips with zippers; when combined with the support member 1, the edge strip 2 is connected and fixed to the support member 1 in a preset manner.

[0054] When the outer jacket 6 is assembled or separated from the supporting component, the lock 33 is pulled to engage or separate the first zipper 3 and the second zipper 5, thereby connecting the outer jacket 6 to the supporting component 1 in a detachable manner.

[0055] Furthermore, the support member 1 is a plate made of wood, hard plastic or metal, which has high structural strength and long service life; the edge banding strip 2 is made of flexible plastic or rubber; it is soft in texture and is easy to connect and fix with the first zipper 3.

[0056] Furthermore, the edge banding 2 and the support member 1 are fixed together by means of an interlocking manner; specifically, an interlocking structure is provided between the edge banding 2 and the outer peripheral surface of the support member 1, and the interlocking structure comprises an annularly extending interlocking groove 12 and a corresponding annular insert 21, and there are two ways of interlocking, one of which is that the annular insert 21 is arranged on the outer peripheral surface of the support member 1, and the interlocking groove 12 is arranged on the edge banding 2; the other way is that the interlocking groove 12 is arranged on the outer periphery of the support member 1, and the annular insert 21 is arranged on the edge banding 2; this interlocking manner has a good fixing effect, and the edge banding 2 will not fall off easily; at the same time, the interlocking manner makes the edge banding 2 easy to disassemble and replace.

[0057] Further, if Figure 1-3 As shown, in this embodiment, the embedding groove 12 is arranged on the outer periphery of the support member 1, and the annular molding 21 is arranged on the edge banding strip 2 for explanation: the embedding groove 12 is extended around the outer periphery of the support member 1, and the embedding groove 12 forms a matching surface 13 outside the notch of the embedding groove 12. The edge banding strip 2 includes an edge banding side wing 22 exposed outside the embedding groove 12 and an annular molding 21 inserted into the embedding groove 12. The first zipper 3 is connected and fixed to the edge banding side wing 22. After the annular molding 21 is inserted into the embedding groove 12, the edge banding side wing 22 is attached to the matching surface 13, so that the edge banding strip 2 and the support member 1 are connected and fixed together.

[0058] Furthermore, the edge banding strip 2 serves as an intermediate carrier connecting the first zipper 3 and the support member 1, and the edge banding strip 2 and the first zipper 3 are fixed together as follows: the edge banding wings 22 are symmetrically formed on the left and right sides of the annular insert 21, and the first zipper 3 is connected and fixed to one of the edge banding wings 22; the first zipper 3 includes a first chain belt 31 and a first tooth portion 32 connected to one end of the first chain belt 31, and the first chain belt 31 is usually a strip carrier made of cloth. The edge banding strip 2 includes an edge banding wing 22 close to the outer peripheral surface of the support member 1, and a mating surface 13 opposite to the edge banding wing 22 is formed on the outer peripheral surface of the support member 1, and the other end of the first chain belt 31 is connected to the edge banding wing 22 by sewing; the sewing method is simple and efficient, which makes the connection effect between the first chain belt 31 and the edge banding wing 22 more secure.

[0059] Furthermore, the other end of the first chain belt 31 is clamped between the edge sealing wing 22 and the matching surface 13 to clamp and fix the first chain belt 31, so that the connection between the first zipper 3 and the edge sealing strip 2 is more stable.

[0060] Further, if Figure 2 , 38, with the middle position of the width direction of the edge-sealing side wing 22 as the boundary, the edge-sealing side wing 22 includes a first side wing 22a and a second side wing 22b, and the other end of the first chain belt 31 is connected to the first side wing 22a or the second side wing 22b of the edge-sealing strip 2 by sewing; the effect produced by the connection between the first chain belt 31 and the first side wing 22a or the second side wing 22b is also different. For example, when the other end of the first chain belt 31 is connected to the first side wing 22a of the edge-sealing strip 2 by sewing, the first zipper 3 and the second zipper 3 are connected. The two zippers 5 are engaged, so that the edge strip 2 is exposed on the outer periphery of the support member 1; at this time, the exposed edge strip 2 can serve as a decoration for the support member 1; when the other end of the first chain belt 31 is connected to the second side wing 22b of the edge strip 2 by sewing, the first chain belt 31 is turned up along the direction of the outer surface of the edge strip 22, and the first zipper 3 is engaged with the second zipper 5, so that the edge strip 22 is covered inside; at this time, the edge strip 2 will be covered by the outer cover 6, so that the support member 1 has a better integrated appearance.

[0061] Further, if Figure 4 As shown, the second zipper 5 is fixedly connected to the connecting edge 62 as follows: the second zipper 5 includes a second chain belt 51 and a second tooth portion 52 connected to one end of the second chain belt 51. The second chain belt 51 is usually a belt-shaped carrier made of cloth. The other end of the second chain belt 51 is connected to the connecting edge 62 by sewing. The sewing method is simple and efficient, which makes the connection between the second chain belt 51 and the main body 61 more secure.

[0062] Furthermore, when the other end of the second chain belt 51 is sewn to the connecting edge 62, a stitch a is generated. In order to prevent the stitch a from affecting the appearance of the jacket 6, the connecting edge 62 is folded inward, thereby forming a folding strip 62a in the main body 61. The second chain belt 51 is connected to the folding strip 62a by sewing, so that the stitching line a can be hidden inside, making the appearance of the furniture more concise.

[0063] Furthermore, in order to enhance the furniture user experience, the support assembly also includes a cushion 4 installed between the main body 61 and the support member 1, with the cushion 4 facing the support surface 11 of the support member 1; when the first zipper 3 is engaged with the second zipper 5, the cushion 4 is covered between the outer cover 6 and the support member 1 and remains in place; when the first zipper 3 is separated from the second zipper 5, the cushion 4 is separated from the outer cover 6 and the support member 1; the cushion 4 can provide comfortable support for the furniture user; the detachable connection between the outer cover 6 and the support member 1 also facilitates the disassembly, washing or replacement of the cushion 4.

[0064] like Figure 5-7As shown, the cover assembly structure in this embodiment can be applied to a sofa or a chair. For example, when the furniture is a chair, the support member 1 is a seat support member or a back support member of the chair. The cover assembly structure is installed as an assembly module s at the back support position or the seat support position of the chair, so that the cover on the seat support member or the back support member of the chair is more convenient to disassemble, wash and replace.

[0065] Embodiment 2: The first zipper 3 in this embodiment includes a first chain belt 31 and a first tooth portion 32 connected to one end of the first chain belt 31, and the edge strip 2 includes an edge wing 22 close to the outer peripheral surface of the support member 1, and a mating surface 13 opposite to the edge wing 22 is formed on the outer peripheral surface of the support member 1; the difference between this embodiment and the above embodiment is that the other end of the first chain belt 31 is bonded to the edge wing 22 or the mating surface 13, and is clamped between the edge wing 22 and the mating surface 13; the use of glue bonding can also make the first zipper 3 and the edge strip 2 tightly connected together, and achieve the same effect as in the above embodiment.

[0066] Example 3: Fig. 9 As shown, in this embodiment, the middle part of the thickness position of the support member 1 has an embedding groove 12, and the embedding groove 12 extends around the thickness position of the support member 1. The edge strip 2 includes an annular embedding strip 21, and the first zipper 3 includes a first chain belt 31 and a first tooth portion 32 connected to one end of the first chain belt 31. The difference between this embodiment and the above embodiment is that the other end of the first chain belt 31 is in the embedding groove 12, and the annular embedding strip 21 is embedded in the embedding groove 12 and clamps the first chain belt 31. Through the embedded extrusion of the annular embedding strip 21, sufficient friction is generated between the first chain belt 31 and the inner wall of the embedding groove 12 and the annular embedding strip 21, so that the edge strip 2 and the first zipper 3 remain relatively fixed, and the same effect as in the above embodiment is achieved.

[0067] Embodiment 4: This embodiment is different from the above embodiments in that Figure 10-11 As shown, in this embodiment, the first zipper 3 and the edge banding strip 2 are integrally formed. The difference is that the first chain belt 31 in this embodiment has a first tooth portion 32 that cooperates with the lock head 33. The first chain belt 31 is not provided, but the edge banding side wing 22 is directly used as the installation carrier of the first tooth portion 32. The first tooth portion 32 can be integrally formed on the outer edge of the first side wing 22a, or integrally formed on the outer edge of the second side wing 22b. This integral molding method can save the assembly steps and time of the first zipper 3 and the edge banding strip 2, reduce the assembly time and cost, and achieve the same effect as in the above-mentioned embodiment.

[0068] Example 5: The difference between this example and the above examples is that in this example, the edge banding strip 2 is fixed to the support member 1 by fasteners (not shown). The fasteners may be third-party parts such as screws or nails. Compared with the interlocking method and the gluing method, the use of fasteners can also stabilize the connection between the edge banding strip 2 and the support member 2 and achieve the same connection effect as in Example 1.

[0069] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
