Description

The present invention relates to a connecting structure between a column and a seat of the most common one-column-type chair among various chairs seated for playing pachinko and slots.

Conventionally, for the seat assembly of a single-post chair, it is screwed with a flange on the upper end of the support on the lower surface of the seat assembly in which a cushioning material rides on a substantially flat seat plate or a plate-like material, It was connected by bolting or welding.
There was a thing which made the support | pillar press-fit or the connection to the leg body on a floor | bed without attaching a flange to a support | pillar by the press fit or welding.

In addition, many seat assemblies for single-post chairs have a slide mechanism in which the seat slides back and forth. In this case, the single post is a slider of the slide mechanism or a slide rail and a flange at the upper end of the post. It was screwed, bolted, or welded together.
In this case, as in the case where the slide mechanism is not provided, there is a thing in which the support column is joined by press fitting or welding to a seat plate without a flange on the support column or a leg body on the floor.
As a reference of the example of the above contents, Patent Document 1 of an example in which a leg and a support are press-fitted together, and Patent Document 2 of an example in which a flange is attached to the top end of the support and screwed are listed below.

In the conventional method of combining the seat assembly and leg assembly of a pachinko chair, when repairing the chair, in the case of welding connection, it is not easy to remove the welded part, and the repair must be performed with the entire chair connected. However, it was much more cumbersome than when it could be disassembled.
In the case of screwing or bolting with a flange, the seat assembly and the leg assembly can be removed only after the chair is turned down or the operator goes under the chair and removes the screw or bolt. Therefore, the structure of easily removing the seat assembly and the leg assembly so that the repair can be easily performed without going to one-touch was an issue.
Not only during repairs, but also in the process of new manufacturing, the housing is bulky, and the trouble of welding, bolting, and screwing the seat assembly and leg assembly that is slightly difficult to hold and assemble with one hand However, it was also a big issue whether it could be omitted.

Means to solve the problem

The present invention is a pachinko chair having a slide mechanism as defined in [Claim 1], and is composed of a seat part assembly having a slide mechanism on a lower surface and a leg part assembly having a column. The cylinder protrudes from the lower surface of the slider fitted to the lower part of the channel-shaped slide rail, and the male taper portion of the upper end portion of the above-mentioned column is fitted into the vertical female taper hole cut from the inner surface of the cylinder to the inside of the slider. Screw the tapping screw into one tapping screw hole on the side of the taper part to be fitted, and the head of the tapping screw protruding from the taper surface will not touch the female taper hole, and the female taper hole and the inner surface of the cylinder. There is a notch in the vertical direction, and the above-mentioned cylindrical tip has ribs along the circumference only at a certain angle in the counterclockwise direction.
A rib with a L-shaped cross section is attached to the inside of the upper centrifugal avoiding the angle of the rib, and a donut-shaped cap with a notch that allows the head of the tapping screw to pass through the hole through which the column passes is upward from below The notch of the cap is displaced by rotation when it is pushed up and rotated at a certain angle, so the head of the tapping screw of the support hits the cap and at the same time the outward rib at the tip of the cylinder is the L-shaped rib of the cap Since each protruding part is up and down, the cap can not be removed from the slider, and as a result, the seat support structure of the pachinko chair column that can prevent the leg assembly from coming off from the seat assembly.

Effect of device

In the present invention described in the previous section, when repairing, put the hand under the sub-assembly, rotate the cap fitted to the lower part of the slider, and lift the seat assembly upward. Detachable.
Also, in the chair manufacturing stage, the sub-assembly and leg assembly are manufactured separately, and finally the horizontal angle of the cap is aligned so that the notch of the cap and the female taper of the slider overlap, and the seat assembly is supported by the column. Lower the top of the tapping head so that the male taper of the slider fits into the female taper of the slider, and turn the cap at a certain angle so that the seat assembly and the leg assembly are combined. The
In this way, the seat assembly and leg assembly can be easily combined, so at the stage of manufacture and sale, the seat assembly and leg assembly can be transported separately and assembled at the storefront and customer site. There are also significant benefits.
