Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a center pillar for a tilting door of a truck for fixing the tilting door pivotally attached to the bed of the truck.

[0002]

[Prior art]

 Aori doors, which are pivotally attached to large trucks and long cargo beds such as trailers, are divided into multiple parts for the convenience of opening and closing. When the cargo was loaded on the cargo bed, it was positioned between the multiple tilting doors, the middle pillar was inserted into the cargo bed, and the tightening device fastened the tilting door to the middle pillar. Also, when the doors were released, the middle pillar was removed from the bed.

[0003]

[Problems to be solved by the device]

 However, the conventional center pillar requires complicated holes for the support part, wastes space, may cause rust on the insertion part, may rust, and may be easily deformed, making it difficult to handle. There were drawbacks such as heavy insertion and removal of pillars, which was dangerous.

The present invention eliminates such conventional drawbacks, and when opening and closing the tilting door, it is not necessary to insert and remove the center pillar from the loading platform, thereby facilitating the opening and closing operation of the tilting door. The purpose is to provide a center pillar for a tilting door of a truck that is made possible.

[0005]

[Means for Solving the Problems]

 The center pillar for a tilting door of a truck according to the present invention comprises a plurality of tilting doors whose lower ends are pivotally attached to the underframe of the truck, and a bottom end which is arranged between the plurality of tilting doors and whose lower end is the pivot axis of the tilting doors. The center pillar that is pivotally attached to the underframe above, a tightening device that fastens the tilting door and the center pillar, a stopper whose one end is pivotally attached to the middle portion of the middle pillar, and the other end of the stopper. And a tightening device for fastening the underframe to the underframe.

[0006]

[Action]

 The center pillar does not need to be inserted into or removed from the cargo bed simply by rotating around the pivotal joint at the lower end, and when opening and closing the adjacent tilting doors together, simply release the tightening between the stopper and the cargo bed. The tilt door can be opened and closed easily.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view of an embodiment of the present invention, and FIG. 2 is a sectional view taken along the line II-II of FIG. 1. As shown in FIG. The lower ends of the doors 2 and 2 are pivotally attached so as to be openable and closable by a hinge 3 arranged in a straight line. A plate-shaped middle pillar 4 is arranged between the plurality of doors 2 and 2, and the lower end of the middle pillar 4 is also pivotally attached to the underframe 1 by a hinge 5. The hinge 5 at the lower end can be rotated to the outside of the underframe 1 around the rotation center. The hinge 5, which pivotally attaches the lower end of the center pillar 4 to the underframe 1, is aligned with the hinge 3 which pivotally attaches the lower end of the tilting door 2 to the underframe 1, and the pivot axis is They are arranged on the same straight line. The tilting door 2 and the center pillar 4 can be integrally fastened by a tightening device 6 such as a shrimp type lock. In the illustrated embodiment, two tightening devices 6 are attached to one tilting door 2, but one tightening device 6 may be attached to one tilting door 2. As shown in FIGS. 1 and 2, the upper end of a plate-shaped stopper 7 that is long in the up and down direction is pivotally attached to the middle pillar 4 approximately at the middle in the height direction and the width direction. The lower end of the stopper 7 can be fastened to the underframe 1 by a tightening device 9 such as a shrimp type lock.

1 and 2, the tilting door 2 and the center pillar 4 are erected, the tilting door 2 and the center pillar 4 are integrally fastened by the tightening device 6, and the lower end of the stopper 7 is also framed by the tightening device 9. In this state, the lower end of the stopper 7 cannot be separated from the underframe 1, so that the center pillar 4 is held in the upright state, and therefore the tilting door 2 is also fixed in the upright state. Will be done.

When two adjacent tilting doors 2 and 2 are opened, the upper end is pivotally attached to the middle portion of the center pillar 4 arranged between the two tilting doors 2 and 2. The tightening device 9 of the stopper 7 is released so that the lower end of the stopper 7 can be separated from the underframe 1 as shown in FIG. As a result, the center pillar 4 can be rotated outside the underframe 1 with the hinge 5 as the center of rotation. Therefore, when the middle pillar 4 is rotated outside the underframe 1 as shown in FIG. Since the hinges 3 and 5 are arranged in a straight line, the tilting doors 2 and 2 integrally fastened on both sides of the center pillar 4 also rotate together with the center pillar 4 about the hinge 3 (see FIG. 1) as a center of rotation. Therefore, by simply releasing one tightening device 9, two adjacent tilting doors 2 and 2 can be opened simultaneously, and it is not necessary to remove the stopper 7 from the underframe 1.

When only one tilting door 2 is opened, if the tightening device 6 of the tilting door 2 is released, the tilting door 2 is separated from the center pillar 4 and can be opened with the hinge 5 as the pivot center. .

When the open door 2 is closed, the operation opposite to the above can be performed to close the door 2 without inserting the center pillar 4 into the luggage carrier.

[0013]

[Effect of device]

 According to this invention, it is not necessary to insert or remove the center pillar, and the tilting door can be easily opened and closed in a short time by a simple operation of simply releasing or fastening the tightening device.
