Description

[Detailed description of the invention] This invention connects pillars in an almost inverted U shape that are arranged in parallel with the leg ends slidably engaged with the rails laid in the longitudinal direction of the axle. Regarding the accordion arch for vehicles that is expandable and retractable,
In particular, a vehicle in which the rail is divided into a long rail fixed to the axle and a short rail fixedly supported by a torii, and the axle can be opened and closed during cargo handling work after folding the arch and moving it to the short rail side. Regarding the accordion arch.

Conventionally, the short rail in this type of accordion arch for vehicles is supported in a cantilevered manner by the torii gate, and is shaped like a truss by means of stays above or below the rail, or both, that connect the rail to the torii gate. Although it is fixed, when the arch is folded and moved towards the short rail side, the weight of the arch tends to deform the torii gate, resulting in irregularities such as steps at the connection between both rails, and the smoothness of the arch. There was a problem with it not being able to open and close properly.

This invention makes it possible to eliminate the level difference in the rail connection part by adjusting the inclination of the short rail even if the rail connection part becomes misaligned due to the deformation of the torii. This allows the arch to open and close smoothly at all times. It has been made possible to do so.

To explain this with the help of drawings, in Fig. 1, 1 is a long rail fixed on the gate 2, 3 is a short rail whose base is pivoted to the torii gate 6, and 7 is one end attached to the torii gate 6.
The stay is pivoted on the upper part so as to be rotatable in the vertical direction, and has a receiver 8 fixed to the other end with an L-shaped cross section, forming a truss, and the square pipe 9 fixed to the lower side of the short rail 3 is attached to the stay. It is adapted to be removably fitted into a fitting portion 8' formed by a receiving plate 7 and a receiving plate 8 (see FIG. 3). Reference numeral 11 denotes a bolt that is screwed into the block 10 fixed to the lower side of the square pipe 9. As shown in FIG. It has the function of a stopper to restrict the rotation of. The short rail 3, whose base is pivoted to the torii gate 6, is supported in a horizontal state by the holder 8 of the stay 7, which prevents downward rotation. Reference numeral 5 denotes a known connector for linearly connecting the long rail 1 and the short rail 3. Although not shown, the leg end is connected to the long rail 1 and the short rail 3 connected by the connector 5. The pillars, which are arranged in a substantially inverted U shape and are slidably engaged with each other, are connected to each other, and an accordion arch that can be expanded and contracted by covering the top with a canopy is attached.

Cargo handling work is carried out by folding the accordion arch toward the short rail 3, removing the connector 5, releasing the connection between both rails 1 and 3, and then folding down the gate 2 together with the long rail 1.

During cargo handling work, as described above, the accordion arch is folded and moved to the short rail side, but the weight of the accordion arch moved to the short rail side deforms the torii 6, causing the short rail 3 to fall forward and move to the long rail. 1, the bolt 11 is screwed in to increase the amount of protrusion from the block 10. As a result, the joint between the bolt protruding end and the receiver side end face moves on an arc _r1 drawn by the receiver side end face, with the pivot point with the torii as the rotation center. That is, the stay 7 tilts upward, and accordingly the short rail also corrects its inclination and becomes horizontal, eliminating the difference in level between the two rails.

The bolt 11 may be screwed in from the receiver side as shown in FIG. 4, and the head 11a may be joined to the end face on the receiver side, and the block 10 may be inserted under the short rail as shown in the same figure. It may be provided directly without intervening the square pipe 9.

In addition, it is preferable that the stay be shaped like a plate with a rectangular cross section so that the amount of stay that protrudes into the luggage compartment is reduced, and square pipes, blocks, and brackets should be placed at the bottom of the rail so that they do not protrude into the luggage compartment or outside of the vehicle body. It is desirable to do so.

As mentioned above, the short rail is supported by the bracket of the stay and will not tilt even if a folded accordion arch is placed below it.
It can be rotated upward. That is, rail 3
When the rail 3 and the stay 7 are rotated upward, initially the bolt tries to tilt the stay 7 slightly upward via the end surface on the receiver side that is connected to the protruding end of the bolt. When rotated, the center of rotation is different, so the distance between the arc r ₁ and the arc r ₂ drawn by the protruding end of the bolt increases, and the protruding end of the bolt and the end face on the receiver side are separated, and from then on the short rail In addition, the stays rotate freely, and as shown in FIG. 1, it becomes possible to fold the short rails upward and the stays downward.
This facilitates cargo handling work at the front of the loading platform. 13 is a chain that connects the upwardly folded short rail and the torii and holds the short rail in an upright state.

In the vehicle accordion arch of the present invention, as described above, the inclination of the short rail that accommodates the folded accordion arch is adjustable, so that the short rail tilts downward due to deformation of the torii. Even if there is a step at the joint with the long rail, the inclination can be corrected by rotating the bolt,
It is possible to easily eliminate the difference in level at the joint.
