Description

[Detailed Description of the Invention] The present invention relates to an improvement of a fixing device for auxiliary legs in a removable cargo platform.

Conventionally, in container-type trucks that have a loading platform that is removably placed on the truck chassis, or trailer-type trucks that can be detached,
Auxiliary legs were provided to support the cargo bed when it was removed from the truck.

However, since this type of fixing device for the auxiliary leg was provided separately from the auxiliary leg, fixing the auxiliary leg (particularly fixing it when it touches the ground) is time-consuming and difficult to perform quickly. There were Q drawbacks such as a large number of parts.

Moreover, in the case where the auxiliary legs are slidably stored on the underside of the loading platform, in order to make the auxiliary legs touch the ground, the auxiliary legs must be pulled out from the underside of the loading platform and then rotated to touch the ground. At that time, there was a risk that the auxiliary leg would be pulled out too much and fall off due to the inertia force due to the weight (load) of the auxiliary leg.

The present invention has been made to solve the above-mentioned conventional drawbacks, and has a simple structure that allows the auxiliary legs to be fixed simply by retracting or touching the ground. The object is to provide a fixing device that will not fall off.

The present invention will be described below with reference to illustrative embodiments.

Reference numeral a denotes a removable loading platform for a truck, and shaft supports 3 for supporting the shaft 2 of the auxiliary leg 1 are fixedly installed at both front and rear ends of the lower surface of the loading platform a.

The shaft receiver 3 has a rectangular tube shape, and both ends 3 of its through hole
The holes a and 3b are square holes that are narrower than the central portion 3c.

Reference numeral 4 denotes a stopper pin provided on the shaft receiver 3, the tip of which is projected by a spring 5 into the central portion 3c of the through hole.

The shaft 2 of the auxiliary leg 1 is attached to the loading platform a at the upper end of the auxiliary leg 1.
square stoppers 6a, 6b are provided near the tips thereof at predetermined intervals, that is, at intervals equivalent to the width of the central portion 3c of the through hole of the shaft 71830. ing.

The length of one side of the stopper is made slightly shorter than the length of one side of both ends 3a, 3b of the shaft receiver 30 through hole.

Therefore, the length of the diagonal line is the length of both ends 3a of the through hole.
, 3b, the stopper 6a is longer than the length of one side of the stopper 6a,
6b can freely slide on the iron part, but is prevented from rotating.

The stoppers 6a and 6b may be formed integrally with the shaft 2, or may be formed separately and fixedly fitted onto the shaft 2.

Reference numeral 7 denotes a pin hole bored between the stoppers 6a and 6b of the shaft 2 at a position facing the stopper pin 4 when the auxiliary leg 1 is in contact with the ground.

Reference numeral 8 denotes a seat that supports the lower end of the auxiliary leg 1 when the auxiliary leg 1 is stored, and is fixed to the lower surface of the loading platform a.

Reference numeral 9 denotes a locking pin swingably provided at the lower end of the auxiliary leg 1, and a hook portion 8 provided on the catch seat 8 when the auxiliary leg 1 is stored.
a to fix the lower end of the auxiliary leg 1.

With the above configuration, when the auxiliary leg 1 is retracted, the shaft 2
The inner stopper 6b of the stoppers provided on the shaft receiver 3 is located at the inner end 3a of the shaft receiver 3, and prevents the shirt 120 from rotating.

(See FIG. 4 (■)) Therefore, even if the lower end of the auxiliary leg 1 should come off the catch 8, the auxiliary leg 1 will not come into contact with the ground.

To ground the auxiliary leg 1, first remove the locking pin 9 at the lower end of the auxiliary leg 1 from the hook portion 8a of the catch seat 8, and then pull out the auxiliary leg 1 in this state.

As a result, the stopper 6b is attached to the center portion 3c of the shaft receiver 3.
Move to.

At this time, the reading aid leg 1 rotates due to its own weight and comes into contact with the ground.

(See FIGS. 5 I and II) After that, the stopper pin 4 that pulls out the auxiliary leg 1 again is inserted into the pin hole T to prevent the auxiliary leg 1 from being pulled out too much.

In this state, the stopper 6a. 6b are located at both ends 3a and 3b of the shaft receiver 30, respectively, so rotation of the shaft 2 is prevented and the auxiliary leg 1 is fixed.

In this embodiment, two stoppers are provided, but the number may be increased to three, so that the two stoppers prevent rotation of the shaft when the auxiliary legs are stored.

In the above operation, the lower end of the auxiliary leg 1 is not in contact with the ground, so by lowering the loading platform support device (not shown) provided on the chassis of the vehicle body and touching the ground using a known method, the loading platform A is moved from the vehicle body by pulling out the vehicle body. It can be cut off from

When storing the auxiliary leg 1, the loading platform a is placed on the vehicle body using a known method, and then the stopper pin 4 is removed and the auxiliary leg 1 is retracted by performing the reverse operation to the above.

As described above, according to the present invention, the auxiliary leg 1 can be pulled out halfway, rotated, and pulled out again, or the stopper pin can be pulled out, pushed in halfway, rotated, and pushed in again. Moreover, since the load of the auxiliary leg is supported by the fitting part of the shaft and shaft holder, it is easy to operate and can be fixed easily, which not only improves work efficiency, but also allows the auxiliary leg to When pulling out the auxiliary leg, the stopper pin is inserted into the pin hole of the shaft to prevent the auxiliary leg from being pulled out too much, which prevents the auxiliary leg from falling off and improves safety. did it.

Further, according to the present invention, the structure is simple, the weight is reduced, and the number of parts can be reduced, so that the installation work is easy and the device can be provided at a low cost.
