Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is designed so that the double doors provided on the rear surface of the luggage carrier of a van type vehicle can be slid parallel to the side walls in the open state. The present invention relates to the structure of a double door that has a sliding mechanism for a van type vehicle.

(Prior Art) Conventionally, a double door that is provided on the rear surface of a loading platform of a van type vehicle is rotated up to about 270 ° outside the width of the vehicle, which is dangerous in a place where traffic is heavy or there are many people. It was

Also, when multiple van-type vehicles move backward to the terminal and are lined up at the terminal of a distribution center, etc., other van-type vehicles can be brought close to both wings within the range where the double door opens. It was not available.

(Problems to be Solved by the Invention) In view of the problems of the prior art, the present invention rotates the double doors by approximately 90 ° with respect to the rear surface of the luggage carrier, and then slides the doors parallel to both side walls to store them along the side walls. It aims to provide a double door structure that does not interfere with traffic.

(Means for Solving Problems) An upper guide rail 10 and a lower guide rail 15 provided along the up-down longitudinal direction of both side walls W of the packing box 1, and the front-rear direction guided by these vertical guide rails 10 and 15. The sliding member S includes a vertical member 4 and an upper lateral member 5 provided on the upper portion of the vertical member 4 orthogonally thereto. The vertical member 4 of the sliding member S includes a double door. 2 is pivotally attached, and vertical member 4
A lower guide roller 13 and a lateral shake prevention roller 1 are provided below
7, a roller support member 8 for supporting a roller 9 rolling on the upper guide rail 10 is provided on the upper lateral member 5.
Is supported, and a stopper 20 that abuts the side surface of the vertical member 4 on the upper surface of the base of the hinge 3, and an upper stopper 2 that abuts the end surface of the roller supporting member 8 on the upper beam 22 that constitutes the rear section opening.
1, the double door 2 can be stored by sliding it along the side walls 2 and 2 of the luggage box 1 which is opened by rotating 90 degrees from the closed state.

(Embodiment) In FIG. 1, reference numeral 1 denotes a luggage box of a van type vehicle, in which a pair of left and right double doors 2 and 2 are pivotally attached to a vertical member 4 of a sliding body S via a hinge 3. The sliding body S includes a vertical member 4 made of, for example, a thick iron plate and an upper horizontal member 5 orthogonal to the vertical member 4, which are assembled with a reinforcing material 6.

When the door 2 is closed, the vertical member 4 is located on the outer side of the vertical beam 7 at the rear section of the luggage box 1. When the door 2 is opened 90 degrees and pushed forward of the luggage box 1, The door 2 can be moved forward along the side wall W.

Reference numeral 8 denotes a roller support member attached to the upper portion of the sliding body S, which has a substantially groove shape, and an upper guide roller 9 is provided on the inner surface of the side wall of the support member 8.
Shaft 9a is attached.

The upper guide roller 9 is guided by the upper guide rail 10 and can roll back and forth. The upper guide rail 10 is fixed to the top and outer sides of the upper frame member 11 of the luggage box 1 with rivets 12 and the like (Fig. 3).

A lower roller 13 (FIG. 3) is attached slightly above the lower end of the vertical member 4 of the sliding body S. The lower roller 13 is guided and rolls on a horizontal portion of a lower guide rail 15 having a Z-shaped cross section, which is attached to a cross member 14 at the bottom of the cargo box with bolts 16 or the like.

Reference numeral 17 denotes a lateral shake preventing roller that is attached upward to a bracket 18 that is attached to the lower end of the vertical member 4, and is a vertical portion of an L-shaped bracket 19 that is fixed to the cross member 14 with a bolt 16 that attaches the lower guide rail 15. It is guided between the vertical part of the lower guide rail. There are two upper guide rollers 9 and one lower guide roller 13 and one horizontal shake prevention roller 17.

Referring to FIGS. 4 and 5, the hinge 3 has its base portion bent at a substantially right angle, and is pivotally supported at the end by the pin 3a on the end face of the vertical member 4. A stopper 20 is provided on the upper surface of the base of the hinge 3.
Is installed. When the door 2 is rotated 90 ° outward, it hits the outer surface of the vertical member 4 and is prevented from opening further.

21 (FIG. 2) is an upper beam 22 that constitutes the rear section of the packing box
The upper stopper fixed to the roller support member 8 when the sliding body S retracts along the side wall W when the door is closed.
The end face of this hits against this, and is prevented from receding any more. Although not shown, another stopper is attached to the upper front portion of the upper frame member 11 so as to correspond to the upper stopper 21 so as not to move further.

Reference numeral 23 is a hole provided in the hinge 3, and a projecting member 23a is fixedly provided on the rear surface of the vertical beam 7 at the entrance of the loading platform corresponding to the hole (fourth position).
Figure). When the door 2 is closed, it fits into the front hole 23 and receives the racking force that is applied to the door.

As shown in FIG. 6, reference numeral 24 is a stopper of the lateral shake preventing roller 17. The stopper 24 is fixed to the back surface of the vertical portion of the L-shaped bracket 19 with spring steel. Stopper 2
Reference numeral 4 is provided so that the sliding body S does not move backward when the door 2 is closed.

When this stopper 24 pulls the sliding body S rearward,
It is pressed by the lateral shake preventing roller 17 and is laterally pressed toward the lateral hole 25 in the vertical portion of the L-shaped bracket as indicated by the chain double-dashed line. When the roller 17 finishes riding, it becomes like a two-dot chain line,
The spring force keeps you from going backwards.

In order to push the sliding body S forward, if it is pushed manually,
The spring steel is bent and pushed out into the lateral hole 25, so that the roller 17 gets over the stopper 24. After the roller has passed over, the stopper 24 returns to its original position.

Although not shown, the stopper 24 is also provided with a stopper in the opposite direction of FIG. 6 at the position of the roller when the sliding body S moves forward and the door 2 is completely stored in parallel with the side wall W. .

(Operation) Opening: 1) To open the door, rotate the lock rod to remove the upper and lower cams and free them.

2) Open the 90 ° door to the side.

3) Push it toward the front of the packing box 1 toward the wall surface W as it is.

4) At the same time the positioning is performed by the front stopper, the lateral shake prevention roller 17 is fixed by the stopper 24 made of spring steel, and the rearward shift is also prevented.

Closing: 1) Pull the door backward to let the lateral shake prevention roller 17 escape from the stopper 24, and further retract it.

2) Stop at the rear stopper 21. Stopper 2 at the same time
4 to prevent backsliding.

3) Close the door 2.

4) Rotate the lock rod to lock.

(Effect) The door is attached to the vertical member of the sliding body that slides through the rollers in the guide rails provided above and below the side wall of the cargo box through the hinge, and the sliding body and the door are integrated along the side wall of the cargo bed. I made it possible to store it. This makes it easy to load and unload luggage even in heavy traffic, and is safe without disturbing people.

In addition, parallel parking of van type vehicles at the terminal can be done by making adjacent vehicles close to each other, so that a considerable number of vehicles can be parked at the terminal in parallel.
