Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a side opening door for a box-type van (hereinafter referred to as a van-type vehicle).

[Conventional technology]

Conventionally, as a door that can be fully opened on the side of a van type vehicle,
There were accordion curtain type and car slider type, but both of them significantly impaired their function when the load collapsed, making them difficult to open and close. The reason for this was that the door had to be slid in the opening/closing direction while receiving load from the load, and the door competed with the cargo, making opening and closing difficult.

Therefore, the door was divided into strips, one end of which was pivoted so that the door could be rotated to open and close, and the shaft was supported so that the door could be moved along the cargo box with the door open. There is an idea in Japanese Utility Model Application Publication No. 52-24616 which is attached to rails having a C-shaped cross section provided vertically on the side of a packing box. However, the door of this prior art has a structure in which the door protrudes inward when the door is rotated, so if the cargo in the cargo box collapses and the door is pushed from the inside. , it becomes difficult or impossible to open the door, and the disadvantage is that the door must be moved one by one when sliding the door.

Therefore, the door was made to be a fully open accordion curtain type door, and a U-shaped groove-shaped guide was formed by the side of the vehicle and a horizontally long holding member that could be rotated outward. Japanese Utility Model Application Publication No. 56-8519 proposes a device in which the door is pressed and supported by the groove, and when the door is opened, the door is moved along the groove. According to the explanation in the same publication, this prior art is recognized as a method of pulling and pressing the lower side of the door to prevent rattling due to vibration.

According to the drawings in the same publication, the outer pressing member is configured to pivotally support the lower side and rotate outward to open the lower side of the door. Therefore, in the event that the cargo collapses, it is possible to open the door by opening the lower side of the door. However, this prior art means for applying pressing force to the presser member uses a lever device, so the device is complicated.
Moreover, there is a drawback that the pressing force cannot be released by a one-touch operation.

[Purpose of invention]

The present invention was developed by focusing on the above-mentioned problem.In a van type vehicle with fully open sides that uses a door divided into strips, the cargo may shift and press the door from the inside. To provide a van-type car door with fully open sides that allows the door to be easily opened even when the vehicle is in a closed position, and that allows each door to be moved in conjunction with each other when sliding the door along the rail. There is.

[Structure of the idea]

In order to achieve the above object, the structure of the completely open side van-type vehicle door of the present invention is to provide a rail at the upper edge of the side opening of the cargo box, and attach the door divided into strips to this rail. The door can be freely rotated and slid around one end of the door in the vertical direction, and
A door that connects the shafts to each other with a cable, that is further pivotally supported at the lower edge of the side surface of the packing box and on the inside of the door, and that presses the hem of the door from the outside at a position lower than the shaft support position. The present invention is characterized by providing an engaging device having a presser foot and a spring that urges the door presser from the outside toward the cargo box.

[Effect]

The door holder of the present invention has the following features: 1) The pivot position of the door holder is provided at a position where the lower edge of the door comes into contact with the holder, so that when the door is pushed from the inside, the door The presser foot acts to push the door back. Therefore, when a force is generated from the inside to push the door outward due to the load collapsing, the door cooperates with the spring to prevent the door from opening. 2) Furthermore, by pushing the door holder downward, the hem of the door can be opened with a single touch. Therefore, if the door does not open due to cargo falling, since the door is suspended as described above, you can easily open the door between it and the cargo by opening the hem of the door and pulling it toward you. can be opened. In addition, since the rotation axes of the doors are connected to each other by cables, it is easy to pull one door to cause the doors to slide in conjunction with each other, thereby opening the doors wide.

Hereinafter, this invention will be explained in detail with reference to embodiments shown in the drawings.

FIG. 1 is an overall view of a van-type vehicle 1 to which the completely open side door of this invention is applied. A plurality of doors 2 divided into strips are provided on the side of a cargo box 10, and the bottom of the door 2 is A door holding channel 8 is provided in the portion 2a. In this embodiment, the door holding channel 8
is divided into three parts in the longitudinal direction of the packing box 10.

In this invention, the door 2 is the upper edge 11 of the cargo box 10.
The structure of this door 2 and the structure of the hanging mechanism are shown in the second,
Figures 3 and 4. The door 2 is provided with positioning protrusions 21 and 25 at the upper and lower parts of the inside, a plurality of cargo stopper protrusions 27 at the center, and engagement key parts 22 and 23 at the front and rear ends. 28 is a sealing member provided on the key portion 22. Each door 2 is suspended from the ceiling of the van type vehicle by a caster wheel 3 attached near one end as shown in the figure. The caster wheel 3 is the door 2
A support shaft 30 implanted in the upper end of the support shaft 3
The door 2 is made up of a shaft 4 rotatably supported at the center of the shaft 4 and rotating rollers 3a attached to both ends of the shaft 4. The van-type vehicle 1 can be moved in the longitudinal direction along the rails 5 by engaging with the rails 5 provided thereon. As shown in FIG. 4, a seal 6 is provided between the rail 5 and the door 2, and the inside of the hem 2a of the door 2 is cut into a tapered shape to fit into the door holding channel 8. ing.

Also, there are hooks 7 at both ends shown in FIG.
The coupling cable 7 provided with a hook 7a sequentially connects the support shafts 30 of adjacent doors, so that the doors 2 can move in conjunction with each other.

Now, FIG. 1 shows the entire state of the van-type vehicle 1 with its sides closed. In this state, each door 2 is in the third
Key parts 22 and 23 provided at the front and rear ends as shown in the figure
are suspended so that they overlap each other,
The key part 22 and the key part 23 are the seal member 28
It is sealed. In addition, as shown in FIG. 4, the positioning protrusions 21 and 25 provided at the upper and lower parts of the inside of the door 2 are connected to the upper guide 12 and floor side guides attached to the ceiling and floor of the vehicle body in this state. 13, and each door 2 is positioned by these recesses 24, 26 for positioning.

Furthermore, in the above state, the hem 2a of the door 2 is pressed against the upper part of the floor side guide 13 by the pressing protrusion 81 of the door holding channel 8, which is biased toward the vehicle body by the spring 82 attached to the lower part of the floor side guide 13. The door 2 is fixed to the cargo box 10 without any play. If the presser protrusion 81 is positioned below the rotation axis 83 of the door presser channel 8, even if a force in the direction of arrow B is applied to the hem 2a of the door 2 due to a load being shifted, etc. Since the component force acts in the direction in which the door holding channel 8 presses down the door 2 as shown by arrow C, there is no danger that the door 2 will open.

Next, in FIG. 4, the door holding channel 8 is rotated in the direction of arrow D against the force of the spring 82, the holding projection 81 is separated from the hem 2a of the door 2, and the rear end 84 of the door holding channel 8 is rotated. Floor side guide 1
By locking the claw portion 91 of the opening hook 9 rotatably provided on the door 3, the hem portion 2a of the door 2 is opened.
can be opened, and the door 2 can be suspended only by the caster wheel 3 at the upper end. That is, the engagement device of this embodiment includes the door holding channel 8,
