Abstract

PURPOSE:To gain height and width of an opening for ease constitutional restrains by fixing the floor and the front and rear walls and making the ceiling and both side walls slidable up and down. CONSTITUTION:A movable part can be elevated by hydraulically sliding stays 7, 8 which are respectively fit to the ceiling of the front and rear walls with the aid of rollers. The lowering motion is completed by reverse sliding of the stays 19, 20. Opening and closing of the side walls may be achieved by the elevation and lowering thereof.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a pan-type freight vehicle having a hexahedral structure in which the floor, front wall, rear wall are fixed, and the ceiling and both side walls are movable up and down, which are fixed separately.

Conventionally, the opening/closing device and opening/closing power of pan-type freight vehicles (hereinafter referred to as vehicles) that can open and close both side walls were attached to a fixed wall to support the movable parts; Space (location) for installation is required, and the fixed wall must also be sturdy, and the rear wall (
5) When opening a door and attaching a door, etc., there are many restrictions due to the structure.
It didn't meet my expectations.

The present invention is an opening/closing structure for a pan-type freight vehicle that can meet the user's wishes without impairing the functions of the vehicle.

Next, the present invention will be explained in detail with reference to the drawings. When the left side wall is opened and closed, the movable part is a stay extending parallel to the surface of the side wall (3) that pivots up and down around the pivot joint (16) on the right side wall. (9) and (10) are connecting shafts (2
4)・Rotate around (25), center (4°24)
・ (25) moves inward by stays (13)-(14), so stays (9), toss (11), (12)
) can only move in the vertical direction, so the connecting shaft (22)
(23) rises while moving between the (17) and (18) axes.

The movable part is raised by hydraulically moving the stays (7) and (8) attached to the front and rear of the ceiling (1) to the rails (on the front and rear walls).
19) and (20) are raised by rotating while sliding.At this time, a roller (15) is attached to the tip to smooth the sliding of the stays (19) and (20).The lowering is done by the stay (19).・It has a structure in which the movable part is lowered by the reverse rotation of (20), the side wall is opened and closed by the above-mentioned lifting and lowering, and the right side can also be opened and closed by lifting and lowering.
