Description

[Detailed Description of the Invention] The present invention relates to a chair mat used mainly for lift chairs in ski resorts and a mat holding device developed for fixing a lift seat plate. Of course, the present invention is not limited to ski lift chairs and mats, but also relates to a presser that can be used when fixing elastic mats to a base.

BACKGROUND ART Recently, it has begun to be installed on the lift chairs of ski resorts with mats that have elasticity and have heat-insulating and heat-insulating effects. In order to ensure the safety of skiers who are carrying this chair mat and to prevent it from being lost due to peeling off, it was not enough to simply attach the mat to the seat board of the lift chair; it was also necessary to attach screws to prevent it from peeling off. .

The conventional technique for solving this problem was to attach the mat to the seat board with special tape and then use bolts to fix the mat at several necessary points. However, such methods require tools such as screwdrivers and spanners, which is cumbersome when working in cold regions.Furthermore, since the fixing means is threaded, there is a risk that the wrist may come off due to vibration during long-term use. Since the bolts and nuts are usually made of metal, there are drawbacks such as discomfort to the body of lift users and corrosion of the seat plate due to rust.

The present invention solves all of the above-mentioned difficulties, the installation work is easy without the need for other tools, there is no risk of it coming off due to vibrations, etc., it does not rust, and it eliminates any strange feeling. The purpose is to provide a pine presser.

The configuration of the present invention is as follows.

A flexible pine holder that attaches and fixes a resilient pine with a through hole drilled in a position corresponding to the mounting hole to a base plate with a mounting hole, and the pine holder head is formed into a flat and wide shape. The belt main body is constructed by consecutively extending the strips downward from the center of the bottom surface, forming a group of locking pieces on one side of the strips, and forming a strip insertion hole in the center of the flat plate. This mat presser is formed by meshing and locking a belt main body with a locking body which is provided with a stopper that meshes with a locking piece of the belt main body in an insertion hole.

Hereinafter, a mat presser for a ski lift chair will be described according to an illustrated embodiment.

As shown in FIG. 1, the present invention includes a lift chair seat plate 2 which is a base with mounting holes 1 drilled therein, and a resilient mat 4 with through holes 3 drilled in positions corresponding to the mounting holes 1. This is a presser for attaching and fixing. The mounting hole 1 here is also a hole passing through the seat plate 2, and the mat 4 may be any material as long as it has elasticity, but in this embodiment, it is a chair mat made of highly foamed polyethylene.

The presser is composed of a belt main body 5 and a locking body 6 formed separately from the belt main body 5. Both members 5, 6
is made of flexible synthetic resin.

The belt main body 5 has a flat disc-shaped pine presser head 7
A belt-like body 8 is arranged in a row downward from the center of the bottom surface, and a group of rack-like locking pieces 9 is formed on one side of the belt-like body 8. The length of the belt-like body 8 is the same as that of the seat plate 2. It is longer than the sum of the thicknesses of the mats 4, and the locking piece group 9 does not need to cover the entire side surface.
As shown in the figure, it is of course sufficient to cover only the necessary areas. As is clear from FIG. 6, each locking piece 11 has an upper tooth tip surface 13 tilted upward from the horizontal.

The locking body 6 is approximately disk-shaped as shown in FIGS. 5 and 6, and has an insertion hole 10 for the strip body 8 in the center.
A stopper 12 is provided in the insertion hole 10 to engage with one of the locking pieces 11 of the locking piece group 9.

The stopper 12 is as shown in FIG.
It protrudes toward the center of the insertion hole 10 from the inner wall 14 so that a play space 15 is created between the insertion hole 10 and the inner wall 14, and the distance between the stopper 12 and the opposite inner wall 14 is slightly smaller than the thickness of the strip. The stopper 12 has a locking piece 11 on the surface that comes into contact with the locking piece group 9.
A stopper protrusion 16 having a tooth tip surface inclined in the opposite direction is formed, and the end thereof slightly protrudes outside the insertion hole 10 to function as a removal knob 17. In the figure, the horizontal portion 18, the thick portion 19, and the uneven portion 20 are all marks for recognizing the direction of the stopper protrusion 16.

Next, to explain how to use the present invention, after attaching the mat 4 to the seat plate 2 of the lift chair in which the mounting hole 1 is drilled so that the through hole 3 and the mounting hole 1 are aligned, The belt body 8 of the belt body 5 is passed through the attachment hole 1 through the through hole 3 and pulled out below the seat plate 2. After that, the belt-shaped body 8 is inserted into the insertion hole 1 of the locking body 6.
0 and bring the locking body 6 into close contact with the bottom surface of the seat plate 2, then pull the strip 8 further downward to slightly dent the mat 4 near the presser head 7, and at that position remove the strip 8. If you release your hand further, the locking piece 11 will move to the stopper 12.
The seat plate 2 and the mat 4 are fixed by engaging with the protrusion 16 of the seat plate 2.

Since the present invention is constructed and used as described above, it exhibits the following effects.

Since the seat plate 2 and the mat 4 are fixed only by the belt body 5 and the locking body 6, no other tools such as a screwdriver or spanner are required, and the installation work is extremely simple.

The mat 4 is fixed not by screwing, but by engaging the group of locking pieces 9 and the stopper protrusion 16,
Moreover, since this interlocking body is made strong by the repulsive force of the elastic mat 4, there is no risk of it coming off due to vibration, and safe fixation is possible at all times.

Unlike the case where the fixing device uses bolts or nuts, the fixing device is made of flexible synthetic resin and the presser foot head 7 is formed flat, so that it does not give a strange feeling to the lift user. There is no problem of corrosion due to the material itself.

By providing the removal knob 17 as in the embodiment, the mat 4 can be removed easily when the lift is not in use by pulling the knob 17 to release the engaged state, making it extremely convenient. be.
