Description

[Detailed Description of the Invention] The present invention relates to a sliding seat support device for an amusement vehicle.

A synthetic resin play vehicle equipped with an operating mechanism for sliding the seat back and forth in order to suit the age and physique of the child is known, for example, from Japanese Utility Model Publication No. 50-22793. However, in this case, the synthetic resin body is simply a single piece with an inverted U-shaped cross section with an open bottom, and the seat is supported from below by its horizontal plate wall-shaped seat mounting section. Because the seat remains in place, the entire body, especially the seat attachment part, must be made thick and rigid for its support strength, and this also prevents the body from cracking or becoming distorted from its open lower edge. It is necessary to prevent it.

In addition, since the seat is assembled to the body only at its approximate center using the only bolt that passes through the bolt hole of the seat and the bolt hole of the seat mounting portion, the sliding During operation, the seat tends to vibrate sideways and the sliding action lacks smoothness, and when the operation is repeated, cracks are likely to form in the seat mounting portion of the body, especially from the area around the assembly bolts. Furthermore,
When the seat is fully extended from the seat mounting portion, the seat is easily bent forward and downward, resulting in an unstable seat support state, which poses a problem in that a large sliding amount of the seat cannot be secured.

The purpose of the present invention is to improve such problems, and its specific configuration will be explained based on the illustrated embodiment. In Figures 1 to 8 showing the amusement car, 1 is a cross section with an open bottom. The upper body is approximately inverted U-shaped, and the lower body 2 is open at the top and approximately U-shaped in cross section, both of which are separately molded in advance from hard synthetic resin. The upper and lower bodies 1 and 2 are fitted into each other at the open peripheral portions facing each other, and are assembled and integrated like a middle cake by being fixed by a required number of bolts and nuts.

3 is a leg opening located approximately in the center of the upper body 1;
This is a seat support bottom wall connected to the rear part of the upper body 1, which is recessed lower than the top wall of the upper body 1, and forms a rectangular horizontal surface in plan view. Reference numeral 5 denotes a sheet placed on the support bottom wall 4, and a slide operation mechanism 6 installed from the bottom of the support bottom wall 4 so as to move back and forth together with the seat allows the seat to be adjusted according to the age and physique of the infant. It is designed to be adjusted by sliding in the front and rear directions accordingly.

That is, 7 is a main slide guide elongated hole which is arranged in parallel as a pair on the left and right in the central part of the support bottom wall 4, and the hole edge is formed by a reinforcing rib 8 bent downward, so that it extends in the front and back direction. It has a long and narrow opening. Reference numeral 9 denotes a pair of left and right regulating legs 9 that protrude downward from the bottom surface of the seat 5 so as to correspond to the elongated holes 7, and by fitting into the elongated holes 7, the seat sliding action is stably regulated. There is. Reference numeral 10 denotes a slide plate horizontally suspended between both legs 9 so as to be orthogonal to both elongated holes 7, and a pair of bolts 11 passing through the seat 5 at the protruding position of the legs 9, and a pair of bolts 11 inserted from below. It is assembled so as to slide together with the seat 5 by means of a screwed nut 12.
