Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a chair cover that is placed over the seat of a chair.

[Conventional technology]

In conventional chair covers of this kind, in order to secure the cover over the seat, a plurality of fasteners attached to the edge of the cover are turned to the side edges of the seat or the back of the seat to lock them, or the cover is secured to the seat. Many have a structure in which the cover is secured by tightening the cover edge with rubber strings or tightening strings attached along the edge.

[The problem that the idea aims to solve]

Among the conventional chair covers mentioned above, those that use fasteners tend to be pulled at the fasteners, causing wrinkles and distortions on the cover surface, which easily spoils the appearance, and it is also troublesome to put on and take off. be.

In addition, since rubber cords or tightening wrinkles are used, there is a narrowing that shortens the attachment edge length, so consideration must be given to the structure so that the chicks produced by this narrowing do not reach the cover surface on the seat. is required,
becomes structurally complex.

For example, the one disclosed in Japanese Utility Model Publication No. 57-3501 uses a wide band-shaped tape knitted with wool or the like, has a non-stretchable border formed on one edge, and has a rubber cord or the like attached to the other edge. The elastic hemming is incorporated to form a stretchable hem, and the non-stretchable hem is attached to the cover edge to prevent wrinkles caused by the squeezing action of shrinking the stretchable hem in the length direction from spreading to the cover surface.

This invention was made in view of the above-mentioned points, and aims to provide a chair cover that has a simple structure, has excellent stability, and can be easily attached and detached.

[Means to solve the problem]

The gist of this invention to achieve the above object is to attach a tightening rod, which corresponds to the corner of the seat and has both ends curved inward to form an elastic tightening section, to the front edge of the cover or The chair cover is characterized by being attached to the rear edge.

[Effect]

When the cover is placed over the seat, the elastic tightening parts at both ends of the tightening rod fold the two corner parts of the cover into the lower side of the seat with the tightening force generated by the shape restoration, and tighten uniformly.

Even if there is a difference in the tightening force of both elastic tensioning parts (a loss of balance) due to the shift of the cover caused by a person sitting on the seat, the tightening force of both elastic tensioning parts will return to its original state after the person leaves. By returning to the balance and balancing the cover, the misalignment of the cover will be automatically corrected.

〔Example〕

Hereinafter, embodiments of this invention will be described based on the drawings.

FIG. 1 is a front view of the cover, and FIG. 2 is a perspective view of the tightening rod.

In the chair cover of this invention, a bag portion 2 is provided on the front edge or the rear edge of the cover 1, and a tightening rod 3 is attached to the bag portion 2.
Both ends of the tightening rod 3 form resilient tightening portions 3' that are curved inward to correspond to the corner portions of the seat.

In the embodiment, the cover 1 is a single rectangular sheet that is slightly larger than the seat of the chair. The tightening rod 3 is made of metal wire, and its elastic tightening portion 3' is curved into a relatively deep circle.The length of the tightening rod 3 is approximately the same as the length of the attachment edge of the cover 1, and under normal conditions, both The two corner parts of the cover 1 are folded downward by the elastic tightening parts 3'.

In the figure, reference numeral 4 denotes a stopper provided on the rear edge of the cover, which is used to fix the rear edge of the cover when the tightening rod 3 is not attached to the rear edge of the cover due to the shape of the seat.

Figures 3a and 3b are perspective views showing how this invention is used.

FIG. 3a shows a case where the seat part A is thin plate-shaped and has a rectangular shape with rounded corners in plan view. Tightening rods 3 are attached to the front and rear edges of the cover 1.

To cover seat A with cover 1, open both elastic tightening parts 3' of tension rod 3 outward against their elasticity, cover seat A with cover 1, and release below seat A. Then, the two corners of the cover 1 are folded into the lower side of the seat A along the seat edge and tightened by the tightening force caused by the shape restoration of both elastic tightening parts 3'.
The tightening rod 3 is stabilized under the seat.

Figure 3b shows a case where the seat A has a backrest B, like a car seat, and the seat A is fairly thick and has rounded corners on both sides of its front edge. be. The tightening rod 3 is attached only to the front edge of the cover 1.

To cover the seat A with the cover 1, open both elastic tensioning parts 3' of the tensioning rod 3 outward against their elasticity, place the cover 1 over the seat A, and then tighten the tensioning rod 3.
When pressed against the front wall of the lower side of the seat A and released, the tightening force due to the restoration of the shape of both elastic tightening parts 3' hugs the corners on both sides of the front wall of the seat A, resulting in a crimped state. In this way, the two corners of the cover 1 are folded in along the edge of the seat and stabilized.

As mentioned above, the seat A having the backrest B generally has a high front edge and a low slope toward the rear edge. Misalignment tends to occur toward the rear of the seat. Therefore, as long as the front edge of the cover 1 is securely fixed, it is sufficient to simply fasten the rear edge of the cover using the stopper 4.

〔effect〕

According to this invention explained above, the following effects are produced.

(a) The cover is fixed using the tightening force created by restoring the shape of the elastic tightening parts formed at both ends of the tightening rod, so the length of the tightening rod attachment edge of the cover does not change and wrinkles around the cover are reduced. Appearance can be improved. In addition, the cover structure can be simplified by attaching the tightening rod directly to the edge of the cover.

(b) Due to the tightening force of the elastic tightening parts formed at both ends of the tightening rod, the two corners of the cover are folded into the lower side of the seat at the corners of the seat and tightened, so the cover has a shape that fits the seat. There is no need for processing such as making it into a bag shape, and the cover structure can be easily formed.

(c) Even if the cover shifts due to someone sitting on the seat,
After the person leaves, the shift of the cover is automatically repaired due to the restorability of balancing the tightening forces of both elastic tightening parts of the tightening rod, so the stability of the cover is good.

(d) The cover can be attached and detached from the seat simply by opening and closing both elastic tightening portions of the tightening rod outward against their elasticity, making it easy to attach and detach the cover.
