Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a loading platform door stopping device for a vehicle such as a truck.

[Prior Art] A so-called three-way opening structure is adopted for the loading platform door of a vehicle in consideration of the workability of the cargo. Such a loading platform door is, for example, as described in Japanese Utility Model Application Publication No. 53-82112 and Japanese Utility Model Publication No. 59-7179,
Furthermore, it is pivoted to the cargo platform and is designed to open outward.

On the other hand, fenders, wheels, etc. are provided at relatively protruding positions on the sides of the vehicle, and therefore, when the side loading platform door is opened, the loading platform door interferes with the fender, etc. For this purpose, it is known that a beam is provided on the side surface of the lower part of the loading platform, and an elastic stopper is provided on the beam as a cushioning material.

FIG. 1 is a perspective view showing a conventional example in which a beam is provided with an elastic stopper. On the side of the loading platform behind the torii gate 2 of the truck 1, a loading platform door 3 is pivotally attached to a floor rail by, for example, a hinge. ing. On the sides of the loading platform are side bumpers 4, fenders 5, and wheels 6.
is provided in a position that protrudes laterally. A suitable number of elastic stoppers 8 are attached to the beam 7 provided at the lower side of the loading platform.

This elastic stopper 8 is intended to prevent the loading platform door 3 from interfering with and colliding with the fender, etc., so the elastic stopper 8 is positioned slightly outward when the loading platform door 3 is opened. The engagement surface with the loading platform door 3 is located slightly outward from the pivot point of the loading platform door 3. However, due to the deformation of the loading platform door 3, this objective cannot always be achieved with the prior art.

That is, as shown in FIG. 2, the loading platform door 3 is pivotally connected to the floor rail 10 on the side of the loading platform 9 by a hinge 11, and theoretically when the loading platform door 3 is opened, the door 3 is opened as shown by the chain line 3a. However, in reality, because the length between the hinge 11 and the elastic stopper 8 is short, the loading platform door 3 is deformed to the position shown by the solid line, and as a result, it interferes with, for example, the fender 5, causing a collision. I once put it away.

[Purpose of the invention] Therefore, the object of the present invention is to provide a vehicle loading platform door stopping device that does not interfere with parts such as fenders that protrude from the lower side of the loading platform door due to deformation when the loading platform door is opened. It is in.

[Structure of the invention] The vehicle loading platform door stop device according to the invention comprises: a cushioning material is attached to a side bumper of a vehicle facing outward, and the side bumper and the vehicle frame are connected in the vicinity of the mounting position of the cushioning material. A reinforcing member is provided.

[Effects of the invention] Since the side bumper is located below the beam, the distance between the hinge, which is the pivot point of the loading platform door, and the cushioning material, that is, the elastic stopper, provided on the side bumper becomes longer, and as a result, The amount of downward deformation when the loading platform door is opened is extremely small, so there is no interference with fenders or the like. Furthermore, since a reinforcing member is provided near the cushioning material, the side bumper itself will not be deformed by the impact force of the loading platform door.

Therefore, the loading platform door does not interfere with the fenders or the like, and the strength of the side bumper itself can be increased by the reinforcing members.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 3 and 4. Note that in FIGS. 3 and 4, parts corresponding to those in FIGS. 1 and 2 are given the same reference numerals, and redundant explanation will be omitted.

The side bumper 4 is made up of horizontal bars 4a, 4a extending horizontally up and down, and an appropriate number of vertical bars 4b extending vertically to connect these horizontal bars 4a to each other, and is connected to the loading platform via stays 12, 13. It is fixed to the bracket 14. In the illustrated example, a cushioning material, that is, an elastic stopper R, is provided at a suitable position on the vertical bar 4b. Since it is preferable that the distance from the hinge 11 be as long as possible in the vertical direction, it is preferably provided near the lower end 3a when the loading platform door 3 is opened. Incidentally, when carrying out the present invention, an elastic stopper 8 may be provided on the beam 7 as an auxiliary, but it is not absolutely necessary.
A reinforcing member 15 has one end fixed to the vertical bar 4b constituting the side bumper 4 near where the cushioning material R is provided, and the other end fixed to the vehicle frame, for example, the chassis 16.

Therefore, when the loading platform door 3 is opened, the loading platform door 3
Since the vicinity of the lower end 3a engages with the cushioning material R,
The deformation of the loading platform door 3 does not interfere with the fenders and wheels protruding laterally at the bottom of the loading platform. Of course, it will not collide with the side bumper. Furthermore, the strength of the side bumper 4 itself is improved by the reinforcing member 15.
