JP4526219B2 - Automatic stopper device for door at 90 ° open position of door in van type vehicle - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
Currently, van vehicles are often used as city delivery vehicles. The door of a van-type vehicle can normally be fully opened to the side of 270 °, but if this is done on the road, it will be very disturbing and dangerous for other vehicles and people.
[0002]
Accordingly, the present invention relates to an automatic stopper device at a 90 ° opening position (a position where the door is substantially parallel to the side of the vehicle) of a door capable of opening 270 ° in such a van type vehicle.
[0003]
[Prior art]
There exists a device for stopping the opening of the door at the conventional 90 ° opening position. However, this has a complicated structure such as using a spring, and the spring is fragile, resulting in malfunction.
[0004]
FIG. 6 shows a state in which a known automatic stopper device at a 90 ° position is attached to the door, and FIG. 7 shows the stopper device. In FIG. 6, a is the body of the vehicle, and b is the position opened just 90 ° by the door. On the inner side of the upper part of the gate pole of the body a, a shaft e, which is urged in the direction of the arrow x in FIG. 7B (inner side of the door ) by the coil spring c having the structure shown in FIG. It is pivotally attached in the character block d. A rod f is fixed to the shaft e perpendicular to the shaft e, a roller shaft g orthogonal to the rod f is fixed to the other end of the rod f, and a roller h is rotatably attached to one end of the roller shaft g.
[0005]
Next, as shown in FIG. 8B, a box body in which a seesaw-like member i is built in is attached to the door b side. In the box, a side plate j and a side plate k are integrally and parallelly attached by an upper plate l . The seesaw-like member i has one end attached to the side plate j with a pin m, and the other end is a coil locked between the edge l ′ of the side plate k and the upper protruding piece n at the end of the seesaw-like member i. The spring p is disposed and is slanted as shown in FIG .
[0006]
A long string q is attached to a roller shaft g for attaching the roller h fixed to the end of the rod f. The roller h is always urged toward the x direction, that is, the inner surface of the door as shown in FIG. 7B by the spring force of the coil spring c. Therefore, when the long string q is pulled forward (opposite to x), the roller shaft g is pulled against the x-direction force of the coil spring c, and the roller h is pulled away from the inner surface of the door.
[0007]
(Operation) When the door is normally opened , the roller h moves while contacting the inner surface of the door by the spring force of the coil spring c (see FIG. 9). The roller h enters the seesaw-like member i on the door side (FIG. 8 (b)) and is locked at the 90 ° opening (FIG. 6).
[0008]
When closing the locked door, push the door slightly inward to release the lock and close the door. When the door is opened 90 ° or more, when the long string q is pulled when the door is opened by about 45 ° (45 ° open state in FIG. 9) , the roller shaft g and the rod f are separated from the inner surface of the door. By further opening the door in this state, the roller h does not enter the seesaw-like member i, and the door can be opened 90 ° or more.
[0009]

DETAILED DESCRIPTION OF THE INVENTION
This will be described with reference to the drawings. FIG. 1 is a plan view of the rear part of the vehicle, and FIG. 2 is a view as seen from the direction of arrow A in FIG. 1 with the door open . 3A is a right side view of FIG. 2, that is, a view seen from the side wall side, and FIG . 3B is a left side view, ie, a view seen from the door side . 4 is a perspective view of the main part of the automatic stopper device, and FIG. 5 is an enlarged view of the end of the long groove formed in the slide holder.
Now, 1 is a side wall of a vehicle (for example, van type vehicle). A side column (rear post) 2 forming a rear section port is attached to the rear end of the side wall. A double door (hereinafter simply referred to as a door) 4 is attached to the rear portion of the side column 2 via a hinge 3.
[0012]
A slide holder 5 having a hat-shaped cross section is fixed to the inner surface of the door 4 with fixing tools 6 at its four corners. In the central part of the convex part of the hat-shaped cross section, a guide long groove 7 is provided in the longitudinal direction. An L-shaped notch 8, which is a notch formed downward so that the long groove 7 is L-shaped, is formed on the rear portion of the long groove 7, that is, on the hinge 3 side of the door 4 (see FIG. 5). An upward semicircular cutout 9 is provided in the vicinity of the L-shaped cutout 8.
[0013]
An arm 10 is guided and slid in a long guide groove 7 provided in the slide holder 5. A pin 11 is attached to the tip of the arm 10 so as not to be removed from the long groove 7 , and the arm 10 is provided with a hinge 13 so as to rotate in a horizontal plane following the opening of the door 4 (FIG. 1). reference). The pin 11 slides along the long groove 7 and falls into an L-shaped notch 8 provided at the end of the long groove 7 to serve as a stopper when opening 90 °. The semicircular cutout 9 is an opening used when the pin 11 is removed from the long groove 7.
[0014]
The other end of the arm 10 that slides along the long groove 7 is hinged to the inside of the side wall 1 of the vehicle via a hinge block 12. That is, the hinge 13 supporting the main portion of the arm 10 is attached to the hinge block 12 fixed to the inner wall of the vehicle so as to be rotatable by the hinge pin 13 '. When the door 4 rotates outward by 90 ° or more, the arm 10 becomes free and is stored in a state of hanging vertically downward ( see an imaginary line in FIG. 4 and FIG . 3A ).
[0015]
The locking device described above is at a height of about 40 to 45 cm from the vehicle floor,
Ordinary worker Ru prone position near the operation on the ground.
[0016]
(Operation) FIG. 1 shows a state in which the door 4 is closed (the slide holder 5 is at the solid line position), opened to the left by 90 °, and stopped at the 90 ° position by the stopper device according to the present invention. Indicates the state. In order to make this state, the door 4 may be opened to the side by unlocking a locking device (not shown) attached to the front surface of the normal door. When opening the door 4 to the side, the pin 11 that is secured to the distal end of the arm 10 with the opening of the door 4 slides in the direction of rotation of the door along the long groove 7 of the slide holder 5.
When the door rotates 90 °, as shown by the chain line in FIG. 1, the hinge 13 opens 180 °, the arm 10 becomes linear, and the pin 11 is above the L-shaped notch 8 at the rear end of the long groove 7. Located in. Since the arm 10 can be rotated in a vertical plane parallel to the side wall 1 of the vehicle by the hinge pin 13 ′, the tip of the pin 11 fixed to the tip of the arm 10 is L-shaped by its own weight at this position. The door can be held in the 90 ° open position without falling into the notch 8 and sliding further.
[0017]
When the vehicle is stopped at the side of the road and unloaded, the door is unloaded or loaded in this state, so the door does not interfere with passers-by or other vehicles.
[0018]
Now, it is necessary, if you want to open even more doors of Figure 1 from the position of 90 ° open, i.e. when the desired 270 ° rotated toward the outside wall of the vehicle, the tip of A over arm 10 the pins 11, remove it manually pushed from the L-shaped notch 8 at the end of the long groove 7, Ru combined pin 11 slightly close the door to the position of the semicircular notches 9. At this position, when the arm 10 is pivoted slightly upward about the hinge pin 13 ′ and further pulled forward and pivoted opposite to the door 4 about the hinge 13, it can be detached from the long groove 7. . When the hand is released, the arm 10 pivots downward about the hinge pin 13 'and falls to the vertical position by its own weight.
Thereby, since the obstacle with respect to the door 4 is eliminated, the door can be opened to the side by opening 270 ° toward the outer wall side of the vehicle . When opened sideways, the position is secured by a conventionally provided stop member (not shown).
[0019]
Conversely, when closing from the 270 ° open position, after unlocking the door 4 and the side wall, manually turn the door, and the pin located at the front end of the arm 10 at a position slightly closed from 90 °. If 11 is aligned with the semicircular notch 9 of the long groove 7 and inserted from here, the state becomes slidable, and the door 4 becomes a 90 ° open type.
[0020]
【The invention's effect】
The automatic stopper device of the present invention is provided with a slide holder fixed to the door and an arm guided by the long groove of the slide holder, and the tip of the arm falls into the notch of the long groove by its own weight at the 90 ° open position of the door. Is held at a 90 ° open position. Therefore, since the door can be automatically stopped at the 90 ° open position by the extremely simplified structure, it is possible to safely load and unload the city area. It can be opened to 270 ° by manual operation, and the door of the van type vehicle can be fully released as before, but the semicircular cutout for removing the arm from the long groove is upward Therefore, when the manual operation is not performed, a situation where the pin at the tip of the arm is detached from the long groove and the door is unexpectedly opened to 90 ° or more is prevented. Further, the arm removed by manual operation rotates around the hinge pin and hangs vertically under its own weight to always be in the same position, so that it can be in a retracted state that does not interfere with unloading or the like .
When the hinge pin is coupled to the hinge block so that the arm is linear when the door is opened 90 ° as in the second aspect of the invention, the door can be accurately stopped at a position of 90 °.
