DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a locking device for an open position of a luggage door in a van type vehicle having a packing box.

[0002]

2. Description of the Related Art The luggage door of this type of van-type vehicle is opened above a double door when loading and unloading luggage. However, if the luggage door is left open, it will be relatively large when used in windy conditions or on slopes. The doors may be hindered by the wind pressure or rocking due to the inclination, thereby hindering the loading operation, and ensuring the safety of workers, and damage to the loading and packing boxes.

[0003]

Conventionally, when a packing box door is opened, a method of fixing a lock bar mounted on the outside of the door to a receiving metal fitting of a packing box outer plate has been adopted. Is difficult to see in a narrow space between the packing box and the door, so there are difficulties in workability, and the brackets attached to the packing box door must not protrude beyond the full width of the vehicle. There is also a demand that it should not be made, it can not be made very strong, and in general, it can not be made very strong because the packing box outer plate is made of aluminum thin plate material, Since is a thin aluminum plate, there are problems in strength against strong winds and difficulty in durability.

As another method, there is a method of pulling a handle having a built-in spring under the floor of a packing box, rotating the handle by 90 °, and hooking the handle to an open door. Although this method has an improvement in workability, it relies on the spring force, and thus has a problem in the function as a stopper due to the bending of the spring due to wind pressure and the durability of the spring.

[0005]

In order to solve the above-mentioned problems, the present invention solves the problem by using a stopper arm attached below the floor of the packing box without attaching a locking part to the packing box outer plate and the door. It is what we are trying to figure out.

That is, in the device according to the first aspect of the present invention, (a) the car body (12) of the van type car (10) is formed behind the carton (14) and is outside the carton (14).

At this time, the projection (54) on the end face of the hollow boss (46) integrated with the stopper arm (28) and the through-hole (3) of the bracket (24) are formed.
6) is locked with the projection (56), and prevents the movement of the packing box door (18), that is, the agitation due to the gust and the unintended rotation on the slope.

[0011] In another embodiment of the invention, there is provided a device for locking a carton door at an open position in a van type vehicle, wherein the projection (5) of the hollow boss (46) is provided.
The fitting hole (64) engaging with (4) is engaged with the through hole (36) of the bracket (24) to prevent the movement of the packing box door (18).

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An apparatus according to the present invention will be described below with reference to the drawings. First, FIG. 1 is a view showing a rear portion of a vehicle body 12 of a van-type vehicle 10, in which an outer wall 16 is formed on a packing box 14 (see FIGS. 2 and 3), and packing box doors 18, 18 are provided.
Is pivotally supported to be rotatable to both sides in the shape of a double door.

The open position locking device 20 of the present invention is schematically shown at both lower ends of the packing box doors 18, 18, and one of the packing doors 18 is indicated by an imaginary line on the right side of FIG. As shown, it is configured to open along the outer wall 16 of the packing box 14.

As shown in FIG. 2, the packing box door 1 of the packing box 14
In the lower part close to 8, a gate-shaped bracket 24 is fixed to the horizontal joist, that is, the lower part of the packing box component member 22, and the bracket 24 can be raised upward from its hanging position via a fulcrum 26. A stopper arm 28 is pivotally supported, and the tip portion 30 of the stopper arm 28 prevents the rotation of the packing box door 18 when the packing box door 18 occupies the open position as described above. In FIG. 2, 32 indicates a vertical joist and 34 indicates a chassis frame.

FIGS. 3 to 5 show the open position locking device 20 schematically shown in FIG. 2 in more detail. FIG. 3 to FIG. A swelling portion 40 is formed at one end of a shaft 38 penetrating through the hole 36, and a split pin 44 is inserted through a small hole 42 provided near the other end to expand the shaft. 38 is prevented from coming out.

A hollow boss 46 is rotatably supported on the support shaft 38 inside the bracket 24, and the stopper arm 28 is integrally attached to the hollow boss 46.

Further, a helical spring 50 is attached to the support shaft 38 via a washer 48 abutting on the hollow boss 46, and is wound around the support shaft 38. Stopper arm 2 integrated with this
8 is pressed leftward in FIG. 4 by the action of the spring 50.

As shown in FIGS. 6 and 7, the end face 52 of the hollow boss 46 (on the side opposite to the side where the washer 48 is fitted) has, for example, a projection 54 over a half circumference thereof.
On the other hand, a protrusion 56 similar to the above is protrudingly provided inside the through hole 36 of the bracket 24 on the side corresponding to the protrusion 54.

A protruding plate 58 protruding integrally from the bracket 24 and a protruding piece 6 protruding from the stopper arm 28
0, a tension spring 62 is contracted, which allows the stopper arm 28 to move smoothly,
The stopper arm 28 performs an auxiliary action to enhance the effect of holding the opened packing box door 18.

The protrusion 54 of the hollow boss 46 in FIG.
9 instead of the locking of the bracket 24 with the projection 56 of the bracket 24.
In this case, a fitting hole 64 corresponding to the protrusion 54 is provided on the bracket 24 side in connection with the through hole 36, and the distal end portion 30 of the stopper arm 28 has just been locked to the packing box door 18. Sometimes, the projection 54 is made to coincide with the fitting hole 64.

By the engagement between the projections 54 and the projections 56 and the engagement between the projections 54 and the fitting holes 64, the stopper arm 28 locks the open position of the open packing box door 18. In order to return the stopper arm 28 to the original state, that is, the position where the stopper arm 28 is suspended, the stopper state is released by displacing the stopper arm 28 to the side, that is, against the spring 50, and the non-use state, that is, the hanging state Have been.

As described above, when the stopper arm 28 is moved from the operating position, ie, the raised position, to the inoperative position, ie, the hanging position, since the tension spring 62 exceeds the dead point of the fulcrum 26, the movement becomes smooth. is there.

[0023]

According to the present invention, the movement of the cargo box door is prevented by the stopper arm in a state where the cargo box door is locked at the open position, and the construction is extremely simple and the operation is safe and secure.
