Chair with removable cover {CHAIR WITH EXCHANGEABLE COVER}

The present invention relates to a chair having a removable cover, and more particularly, since the manufacture of the removable cover applied to the chair is completed by one injection of resin mold, the manufacture of the cover itself can be easily and inexpensively performed. Due to the cover is excellent seating comfort, easy to remove and assemble with the chair frame for washing or replacement of the cover, and to the chair having a detachable cover that can be combined invisibly combined with an attractive appearance.

In general, the components constituting the chair include a body support such as a seat plate, a backrest, an armrest and a head rest, and the body support of the chair has a structure coupled to a frame forming a skeleton.

By the way, each of the chair body support portion of the chair is covered with a flexible, flexible seat cover, such as cloth, artificial leather or natural leather to improve the seating comfort and provide a beautiful appearance on the front or the entire base of the base. Here, the method of covering the seat cover on the base is various, but the most common method used in the manufacture of a conventional chair, after combining the cover member made of the material, such as a plate made of plastic injection molding, etc., the fixing piece and the seat again The base to be covered was made in such a way as to be mutually coupled using a fixing bolt or the like.

However, in this method, since the fixing pieces of the base and the seat cover must be combined by using fixing bolts as described above, a lot of labor is required in assembling, and as a result, productivity decreases and manufacturing costs increase. In addition, since the seat cover used in the chair is exposed to the outside when used and directly contacts the body, there is a great possibility of contamination and damage, so it is necessary to periodically clean or replace it. Depending on the tendency, it is necessary to change the seat cover made of various cover members having different textures or patterns.

Therefore, while the cover sheet is firmly combined so as not to be inconvenient to use normally, it is urgent to develop a structure that can be easily removed from the base and reinstalled at the time of exchange. The seat cover, which is fixed and combined with the base and bolted structure again, is very cumbersome to remove, and even if detachable, it is difficult to separate and wash the cover member such as fabric, and it is necessary to replace the fixing piece so that the seat cover can be replaced. There is a problem that the cost is excessive.

In order to solve the problems of the prior art as described above, the present invention is easy and inexpensive to manufacture the cover itself because the manufacture of the removable cover applied to the chair is completed by a single injection of the resin mold, the cover of the network structure Due to the excellent seating comfort, easy to separate and assemble with the chair frame for washing or replacement of the cover, and to provide a chair having a detachable cover that can be combined invisibly combined with an attractive appearance. do.

In order to achieve the above object, the present invention

The fixing piece is coupled to the upper surface of the cover cloth formed integrally through the injection of the resin mold, the coupling piece is coupled to the lower surface of the cover cloth, and the fixing piece through the through hole located between the fixing piece and the coupling hole And a binding portion made of an adhesive portion for joining the coupling sphere and attached to the edge of the cover cloth; And

It provides a chair having a removable cover characterized in that it comprises a body support of the chair having a corresponding coupling to detachably couple the coupling in a shape corresponding to the coupling of the engaging portion.

According to the chair having a removable cover of the present invention, since the manufacture of the detachable cover applied to the chair is completed by one injection of resin mold, the manufacture of the cover itself can be easily and inexpensively performed, and the seating feeling due to the cover of the network structure This is excellent, easy to separate and assemble with a chair frame for washing or replacement of the cover, there is an advantage that the appearance is beautiful because it can be combined invisible combination.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a chair having a removable cover having a plurality of through-holes penetrating the upper and lower surfaces of the cover cloth 10 made of a network structure; Fixing piece 22 to be coupled to the upper surface of the cover cloth 10 is formed integrally through the resin mold injection, coupling tool 24 to be coupled to the lower surface of the cover cloth 10, and the fixing piece 22 and A binding portion 20 made of an adhesive portion that penetrates the through hole positioned between the coupling hole 24 and joins the fixing piece 22 and the coupling hole 24 and is attached to an edge of the cover cloth 10. ; And a body support part 30 of the chair having a corresponding coupler 32 that detachably couples the coupler 24 to a shape corresponding to the coupler 24 of the engaging portion 20. It is constructed.

That is, as shown in Figures 1 to 8 a specific example, the cover cloth used in the cover is a molten resin in the upper surface of the cover in order to be able to manufacture and combine the binding portion to be described later by the resin molding method It must have a plurality of through-holes penetrating the upper and lower surfaces so as to pass between and and the lower surface, and the user having a seat structure to the chair should have a comfortable sitting feeling made of a cloth having a network structure. The density of the network structure of the cover cloth 10 is determined by whether the molten resin can pass between the upper and lower surfaces of the cover cloth 10 during the resin molding process of the binding portion 20, and thus the network structure is It is a meaning containing both a normal network structure and the woven structure which satisfy | fills the said conditions.

In order to couple the cover cloth 10 to the body support of the chair (for example, the seat plate, the backrest, the armrest, the head rest, etc. of the chair), it is necessary to provide a binding portion to the cover cloth, which is described above. Since it has a network structure having a through hole that satisfies the conditions, it is manufactured by carrying out the molding of the binding portion and the coupling between the binding portion and the cover cloth through a single process through injection of a resin mold. To the edge of the cover cloth.

That is, the binding portion 20 formed in this way is a fixing piece 22 to be coupled to the upper surface of the cover cloth 10, the coupling member 24 to be coupled to the lower surface of the cover cloth 10, and the fixing piece An adhesive part for penetrating the through hole positioned between the 22 and the joining hole 24 to join the fixing piece 22 and the joining tool 24 (which is the resin melted in the resin molding process, is a through hole of the cover cloth). And a part soaked in the cover cloth, not shown). Here, the fixing piece 22 serves to firmly attach the binding portion to the cover cloth, and preferably, as shown in the specific examples of FIGS. 1 to 2, a plate shape (must be a flat plate shape). And a curved plate of concave or convex shape, as shown. This makes it possible to reduce the cost of materials, avoid interference, and provide beauty by constructing a rigid attachment in a small volume.

The coupler 24 serves to prevent the cover cloth 10 to be coupled to the body support of the chair so as not to be separated, as shown in FIG. can do. Preferably, the coupler is shown in Figures 3 to 4, 7 and 8 as shown in the specific example i) protrusions (in case of having only protrusions independently) or ii) a plurality of the protrusions and connecting them Ribs (as shown in FIGS. 3 to 4 and 8, the independent projections further have a rib structure connecting them to each other, and the structure is connected to each other, these projections may be connected as shown in Figure 8, As shown in FIGS. 3 to 4, only a part thereof may be connected. In addition, as shown in (d) of FIG. 6 or 7, the end of the protrusion may be made thicker to prevent it from being easily separated after assembly.

Since the fixing piece and the coupler are respectively disposed on the upper and lower surfaces of the cover cloth, a separate coupler is required in order to connect them. When the molten resin through the through-hole of the cover cloth to move from the upper surface to the lower surface or from the lower surface to the upper surface to combine with each other to form and bond in a single process, the bonding can also be made evenly and powerfully.

Wherein the cover cloth and the fastening portion of the fastening portion and the engaging portion can be arranged in a variety of vertical position as shown in Figure 6, in the case of Figures 1 to 4 in Figure 6 (b) Corresponds to the corresponding configuration.

The combination of the cover cloth and the binding portion thus formed is detachably coupled to the body support of the chair, preferably the seat plate or the back of the chair or the armrest or the head rest. To this end, the body support 30 of the chair is the binding portion ( It is provided with a corresponding coupler 32 for detachably coupling the coupler 24 in a shape corresponding to the coupler 24 of (20). The process of coupling the cover cloth combined with the binding portion to the body support is as shown in FIG. Of course, the cover cloth can be tailored to keep it taut to prevent any separation, and the protrusions of the coupler can be configured longer.

The corresponding coupler may be configured in various shapes according to the shape of the coupling portion of the binding portion, i) when the coupling portion is a projection, the corresponding coupling portion is a hole for receiving the projection shape and ii) when the coupler is a plurality of the protrusions and ribs connecting them, the corresponding coupler is a hole for receiving the plurality of protrusions and a groove shape for connecting the protrusions. As shown in FIG. In particular, in the case where the projections of the coupler have larger ends as shown in FIGS. 6D and 7, the corresponding coupler has a corresponding shape as shown in FIG. 7. You can prevent it from happening. In this case, since the corresponding coupler and the coupler are generally made of a resin having a wide elastic deformation region, their coupling may be possible by simply pushing.

In addition, in order to prevent such arbitrary separation, it may be preferable to further include a fixed coupler for fixedly coupling the coupler to the corresponding coupler, and as described above, In addition to the method of making it thicker, an additional coupling hole may be added to the upper surface of the fixing piece, and the fixing pin may be inserted into and coupled to the body support part.
