DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface covering material applied to the back or seat of a chair.

[0002]

2. Description of the Related Art This type of surface covering material is arranged at a position for covering the surface of a chair back or seat, in order to protect them from stains and damages and to improve the feeling of contact. It works effectively.

FIG. 10 shows a backrest a of a general chair to which a surface covering material c is applied. The backrest a includes a plate-shaped back member b and a cushion member (not shown) attached to the front surface of the back member b. In order to wrap and protect the back member b and the cushion member integrally, the surface covering material c is sewn into a bag-like member having an opening d. Then, the opening d is covered from the front side of the backrest a so as to wrap around the periphery thereof, the opening d is positioned on the back side of the back member b shown in the figure, and the ribbon e is arranged along the inner peripheral edge of the opening d. The surface covering material c is fixed to the back member b by applying a nail f or the like to the back member b from above the ribbon e and penetrating the periphery of the opening d from above the ribbon e.

[0004]

However, in such a case, the surface covering material c is easily damaged at the time of driving the nails f and the like, and moreover, it is not easy to replace the surface covering material c, so that the surface covering material c is damaged or damaged.
Alternatively, there is a drawback that it is not possible to promptly deal with replacement due to seasonal changes and the like. When the surface covering material c is extremely soiled or damaged, it is often uneconomical to discard the entire chair.

Therefore, in order to eliminate such a problem, the surface covering material g schematically shown in FIG. 11 is formed by folding back the inner peripheral edge of the opening h to sew a bag-shaped mounting portion i, and then mounting the mounting portion i. It is constructed by inserting a tightening cord j into i. The tension h is closed by tightening the tightening cord j, and conversely, the opening h is widened to tighten the tightening cord j. Is configured to be relaxed. By doing so, the front covering g can be stretched or loosened by operating the tightening cord j or the opening h with the opening h positioned on the back surface of the backrest, so at least the backrest. The convenience of attachment and detachment work can be effectively improved.

However, in order to manufacture such a surface covering material g, a sewing operation for a mounting portion for passing the tightening cord j, that is, a folded-back portion i, and a tightening cord j in the mounting portion i after sewing are performed. And the work of inserting it becomes indispensable. For this reason, there is a problem that the number of manufacturing steps of the surface covering material g increases, and the work must be extremely complicated.

The above-mentioned problems are not limited to the backrest and can be applied to the surface covering material applied to other body members such as a seat.

The present invention has been made in view of the above problems, and can be applied to a backrest, a seat and other main body members for easy attachment / detachment and replacement. Moreover, the present invention is easily manufactured. The object is to provide a surface covering material that is made possible.

[0009]

In order to achieve the above object, the present invention employs the following configuration.

That is, the surface covering material of the present invention has an opening and is removably arranged at a position where the surface of the main body member is covered through the opening. The overlocking thread sewn along the peripheral edge and the position at which both ends of the overlocking thread are indirectly sewn along the inner peripheral edge of the opening to a substantially circumferential position and both ends of the overlocking thread are pulled out from a part of the overlocking thread. A tightening cord arranged on the opening, the opening is closed by tension of the tightening cord, and the tightening cord can be loosened by expanding the opening. To do.

[0011]

With this structure, if the front cover is covered on the main body member from the front side and the opening is positioned on the rear surface of the main body member, both ends of the tightening cord can be grasped and pulled. The opening can be closed and the surface covering can be tightly attached to the main body member. Further, if the opening is closed in that state and the opening is closed and pushed in the direction of expansion, the surface covering can be loosened and easily removed from the main body member. Thus, the surface covering material of the present invention can be easily attached to and detached from the main body member.

Moreover, the tightening cord is indirectly sewn to the inner peripheral edge of the opening at the same time as the step of overlock stitching. Therefore, it is possible to completely eliminate the work of forming the attachment portion of the tightening cord on the surface covering material in a separate step, the work of inserting the tightening cord through the attachment portion, and the like.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

The surface covering material 1 is applied to a backrest 2 of a chair shown in FIG. 1, for example. As shown in FIG. 2, the backrest 2 is configured by using a resin shell 21 as a backup member and attaching a cushion material (not shown) to the front surface of the shell 21. It is attached to the upper end of the back support rod 3 protruding upward. Then, the backrest 2 is covered with the front covering material 1 from the front side, and the front covering material 1 is fixed at a position wound on the back surface, and then the resin cover 4 is mounted.

The surface covering 1 is, as shown in FIGS.
A front cover 11 made of cloth or sheet material cut into a shape substantially corresponding to the backrest 2 and a cloth or sheet material cut into a shape substantially corresponding to the backrest 2 and having an opening 13 at the center. After-cut coating 12 formed by cutting
The front and rear covering portions 11 and 12 are sewn to each other at their peripheral portions and turned upside down to form a bag.

In the surface covering material 1 as described above, the inner peripheral edge 13a of the opening 13 of the rear covering portion 12 is subjected to overlock stitching (sewn means by overlock) which is a general method for preventing fraying. However, in the present embodiment, when the overlocking thread 5 is sewn in, the tightening cord 6 is sewn at the same time along the inner peripheral edge 13a of the opening 13. More specifically, a tightening cord 6 longer than the circumferential length of the inner peripheral edge 13a of the opening 13 is prepared, and the tightening cord 6 is formed into a loop shape such that the middle portion is along the inner peripheral edge 13a of the opening 13. After being bent and arranged, the looped thread 5 is trapped in the middle portion of the thread as shown in FIG. 5 from the start end portion to the end portion of the loop.
Sew in. That is, while the tightening cord 6 is always located on the surface covering material 1 side with respect to the overlocking thread 5, and while the overlocking thread 6 is never directly sewn into the tightening string 6, Inner peripheral edge 13a of the opening 13
Sew the overlocking thread 5 along the line. Then, at the time when the overedging is completed, both ends are arranged at positions where a part of the overedging thread 5 is pulled out to the outside. In this state, the tightening string 6 is movable along the longitudinal direction in the stitches of the overlocking thread 5, and the tensioning operation and the loosening operation are performed without any trouble. Therefore, if both ends of the tightening cord 6 are gripped and tensioned, the opening 13 of the surface covering material 1 is narrowed and closed, and conversely, if the opened opening 13 is handed and spread, it will be in the thread. After the tightening cord 6 is pulled in, the tightening cord 6 is operated.
Will be relaxed.

Therefore, if this surface covering material 1 is used,
By covering the backrest 2 which is the main body member and pulling the tightening cord 6, the surface covering material 1 can be easily adhered to the surface of the backrest 2 in a tensioned state, and the tightening cord 6 is held at that position. The surface covering 1 can be fixed to the backrest 2 by tying both ends of the back cover. Then, after that, the resin cover 4 larger than the opening 13 is attached to the back surface of the backrest 2 by using an appropriate engaging structure, so that the opening 13, the overlocking thread 5 and the tightening string 6 are attached to the back support. It is possible to improve the appearance of the chair by blindfolding it together with the upper end portion of the rod 4. On the contrary, if the resin cover 4 is removed from this state, the knot of the tightening cord 6 is unwound, and the closed opening 13 is put into the hand and pushed in the direction of expansion, the tightening cord 6 is pulled into the thread. Since it gradually falls and becomes a relaxed state after the operation, the surface covering material 1 is loosened and can be easily removed from the backrest 2.

Thus, the surface covering material 1 of this embodiment
Makes it possible to attach and detach the backrest 2 extremely easily.

Moreover, in the surface covering material 1, the inner peripheral edge 13a of the opening 13 is simultaneously formed at the time of the step of sewing the tightening cord 6 by overlocking.
Can be sewn indirectly to. For this reason, it is possible to completely eliminate the processing work of a special mounting portion for inserting the tightening cord 6 and the work of inserting the tightening cord into the mounting portion, which are required in the related art. It is possible to surely reduce the manufacturing process and the labor and cost associated therewith as compared with the surface covering material.

The specific construction of each part is not limited to the above-described embodiment, but various modifications can be made without departing from the spirit of the present invention. For example, although the above-described embodiment has been described with respect to the case where the surface covering material of the present invention is applied to the backrest of a chair, the same operational effect can be obtained even when applied to the seat of the chair. Further, although the resin cover is shaped so as to cover the entire back surface of the backrest in the above-described embodiment, it may be a part of the backrest as long as it can cover the periphery of the opening. Of course, it is also possible to use it without attaching the resin cover at all. 6 to 9 illustrate a chair according to another embodiment including some of these modifications. That is, for the chair back 102 and the seat 107, the surface covering materials 101a, 1
01b is coated on the backrest 102 of the surface covering material 10
The opening 113, the tightening string 106, the overlocking thread 105 and the like are exposed as they are on the back surface of the la 1a. Backrest 10
2 has a structure in which a cushion material 122 is attached to the front surface of a plate material 121, and the seat 107 has a similar structure.
This chair can be used not only for the backrest 102 but also for the seat 107 to wash the seat 107 more quickly and to prevent stains or damage.
It becomes possible to easily perform replacement for repair, or replacement for summer and winter according to the change of seasons. Moreover, even when the backrest is not attached in this way, the overlock stitch has a decorative stitch-like element, and if the coloring of the sewing thread is changed as necessary, it is an innovative alternative to the conventionally used ribbon. The aesthetic appearance is exhibited, and it is not inferior to a ribbon or the like even without wearing a backrest.

[0021]

As described above, the surface covering material of the present invention is configured so that the opening portion required for attachment / detachment to / from the main body member is expanded / contracted by utilizing the tension and relaxation of the tightening cord. At the same time, the tightening cord is indirectly attached to the inner peripheral edge of the opening when the inner peripheral edge of the opening is sewn. For this reason, it is possible to achieve both easy attachment / detachment with respect to the main body member and reduction of man-hours for attaching to the tightening cord, which is easy to replace, convenient to use, and easy to manufacture, and put to practical use.
