Description

[Detailed Description of the Invention] The present invention relates to a gate provided with a pandagraph type telescoping mechanism, and specifically relates to a telescoping gate used on a slope.

This type of telescoping gate has been widely used in recent years because the gate body opens and closes in a straight line, making efficient use of site space, but it is extremely difficult to install it on a slope. .

In view of these circumstances, the present inventor made a thorough study and found that the diagonal members 1, 1, etc. are inclined in opposite directions at the front and back, and the intersection position is set at the pin axis 2°2.・・・・・・
・In a gate having a pandagraph type telescoping mechanism, which is rotatably supported on a pivot, a fixed side frame 3 and a movable side frame 4 are provided at the side ends, and casters 5 are provided at the lower end of the movable side frame. When connecting the end of the door body to the fixed side frame 3, which is rotatably mounted on the support column 6 and the horizontal plane, the vertical direction is set at the upper and lower parts of the fixed side frame 3 at positions corresponding to the pin shafts 2, 2 of the end of the door body, respectively. The pin shafts 2, 2 at the ends of the door body are inserted into the slit grooves, and the pin shafts 2, which are inserted into the slit grooves 7 provided above, are pushed downward by the springs 8. By providing more support, the intended purpose was achieved.

When implementing this project, in order to attach the fixed side frame 3 and fixed support 6 of a gate having a pandagraph type expansion/contraction mechanism so that they can rotate freely in a horizontal plane, for example, as shown in the figure, it is necessary to attach the fixed side frame 3 and fixed support 6 to the fixed support 6 buried underground. It is sufficient to insert the fixed side frame 3 formed as a hollow columnar body, and the spring 8 that supports the pin shaft 2 from below, which is inserted into the slit groove 7 provided above the fixed side frame 3, is shown in Fig. 4. As shown in FIG. 2, the vertical position of the door body can be adjusted by dividing it into upper and lower parts and inserting an adjustment rod 9 between them.

In the figure, 10 represents a bearing.

The present invention has the above-mentioned configuration, and when connecting the end of the door body to the fixed side frame 3 which is rotatably mounted on the fixed support column 6 in a horizontal plane in a gate having a pandagraph type telescoping mechanism,
At the upper and lower parts of the fixed side frame 3, vertically elongated slit grooves 7 are provided at positions corresponding to the pin shafts 2, 2 at the end of the door body, respectively.
7 and the pin shaft at the end of the door body is inserted into the slit groove, so even if the gate moves up and down along the undulations of the road surface that the casters 5 at the lower end of the movable side frame 4 come into contact with, the snot does not occur. Since the pin shafts 2, 2 inserted into the grooves 7, 7 move up and down according to this movement, the door body can always maintain its normal posture, and the fixed support 6 and the fixed side frame 3 can be rotated in a horizontal plane. Since it is movable, the door body can be folded and rotated back and forth for storage.
In this case, there is no problem even if there is an inclination in the front-rear direction, and the door can be opened and closed smoothly even if it is on a slope in the front-rear, left- or right-hand direction. Since the pin shaft 2 inserted into the shaft 7 is supported from below by the spring 8, as the caster 5 attached to the lower end of the movable side frame 4 moves up and down along the undulations of the road surface, the slit groove It serves as a buffer when the pin shafts 2, 2 inserted into the pins 7, 7 move up and down, smoothing the vertical movement of the door body, and has a remarkable practical effect.
