Description

Cover for covering sponge of seat cushion or seat back}

The present invention relates to a finishing material for the back and seat of the chair, and more particularly, the core material is stitched along the edges so as to cleanly finish the cushion material of the back and the seat of the chair to improve aesthetics and improve durability. A finishing material for back and seat of chairs.

Generally, the chair can be manufactured in various forms according to its use. However, the chair is generally divided into a back seat and a seat plate, and a fixed seat chair composed of support bars mounted on all sides of the seat plate to support the seat, and also the bottom of the seat plate. A rod-shaped rod is mounted in the center, and a pedestal with a roller is mounted at the lower end of the rod, so that it can be classified as a movable chair.

Looking at the detailed configuration of the back plate and the seat plate, it is composed of a sponge material which is located inside the back plate and the seat plate to provide a substantial cushion, and a finishing material (leather, cloth, leather) that wraps the sponge material and contacts the actual user. On the bottom of the sponge material of the seat plate, a plastic or metal extruded product that serves as a skeleton and a support of the chair is mounted.

The conventional manufacturing process surrounding the finishing material on the back plate and the seat plate is as follows.

Applying an adhesive to upper surfaces of the sponge material for back plate and seat plate; Attaching a finishing material (such as a synthetic resin material or a soft material cloth) to an upper surface of the adhesive-coated sponge; The edge of the finish is pulled toward the bottom edge of the sponge material, and then closely adhered to the bottom edge of the sponge material.

However, as the needle continuously fires the needle along the edge of the finish with a mechanism called Taka, the needle 16 is exposed to the outside as shown in FIG. ) Is separated, there is a disadvantage that the finish (10b) is easily dropped.

In particular, when the saliva is detached or dropped, there was also a safety problem of being injured while in contact with the user's body.

Therefore, the present invention has been devised in view of the above, and completely eliminates the conventional method of fixing the finish with a needle by the Taka mechanism, the finish state for the back and seat sponge material to improve the clean and durable It is an object of the present invention to provide a finishing material for the back and seat of the chair which can combine safety.

<Explanation of symbols for the main parts of the drawings>

10a, 10b: Finish 12: Core

14: sponge material 16: needle

The present invention for achieving this purpose is:

While having an area that can wrap the backrest and seatboard sponge material of the chair, the core material is built in by the edge of the sewing, both ends of the core material is characterized in that it is exposed to the outside to be pulled and bundled.

Preferably, the core is characterized in that the thick thread.

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

1 is a perspective view showing the back and seat plate finishing material of the chair according to the present invention.

The finishing material 10a for the back and seat of the chair of the present invention is wrapped in a sponge material of a chair that provides a substantial cushion, so that the finishing treatment can be neatly arranged, and wrapped in sponge materials of different sizes according to the type of chair. It has an area that can be built into the sponge material at its edge.

In particular, the finishing material (10a) of the present invention is characterized in that the built in the sponge material (12) along its edge, the method of embedding in the sponge material put the core material 12 at the edge of the finishing material (10a) Use a sewing machine to sew.

Of course, after sewing the passage in which the core can be inserted into the edge of the finishing material in advance, it is also possible to insert the core in the passage, but as described above to ensure that the core material is continuously provided at the edge of the finishing material when sewing the sewing machine Preferably, the core material is to be sewn at the same time along the edge of the finish.

At this time, both ends of the core material is partially exposed to the outside to be pulled and bundled at the position where they meet each other.

The material of the core material is preferably to use a thick thread having the advantage of easy to bundle, easy to pull, in addition, any material can be used as long as the material can be pulled and bundled.

The finishing material of the present invention provided as described above will be described with reference to FIG. 2 attached to a state of wrapping the sponge material for the back and seat of the chair as follows.

First, after applying an adhesive to the upper surface of the sponge material for back plate and seat plate 14, the bottom surface of the finishing material (10a) of the present invention is attached to the upper surface of the sponge material 14 coated with the adhesive.

Next, the sponge member 14 is turned upside down, the edge end of the finishing material 10a is pulled toward the bottom edge of the sponge material 14 to be in close contact with each other, and then the core material 12 embedded at the edge end of the finishing material 10a is pressed. Both ends are pulled tight with a predetermined device.

Subsequently, by tying both ends of the taut pulled core material 12 together, by cutting and finishing a portion other than the tied knot, the finishing material 10a of the present invention is finished on the sponge material 14. will be.

In this way, by wrapping the finish material of the present invention in a sponge material, and then by pulling the core material tied, the finishing state is neat and organized, the appearance can be improved, durability can be increased, and the existing Takagi It is possible to prevent injury to the body by the needle.

As seen above, according to the finish of the back and seat of the chair according to the present invention, after wrapping the sponge material for the back and seat of the chair with a finishing material with a core material, and then clean the finishing treatment, for the sponge material The finishing condition is clean and can improve the durability, and can improve the workability for finishing.

In addition, it is possible to prevent the point of injury caused by contact with the body while falling by the conventional taka mechanism.

In addition, the existing equipment such as Taka mechanism and a separate air generating device is excluded, it is possible to reduce the equipment cost.
