Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hood bone traveling device for a telescopic hood for a small truck.

[0002]

2. Description of the Related Art Conventionally, it is customary to cover a pickup stand of a pickup or delivery van type small-sized freight vehicle with a cover each time to prevent rainwater, but the work of removing and attaching the cover is troublesome. Not only that, it was difficult to reliably prevent rainwater.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a hood bone traveling device which has various advantages of an expandable and retractable hood for a small freight vehicle devised to solve the above problems.

[0004]

The features of the first device of the present invention are as follows.
Angle-shaped wheel holding plates are attached to both ends of a hood bone, which is attached to the back surface of a hood cloth covering a loading table of a small-sized lorry vehicle at predetermined intervals in the front-rear direction, so as to be rotatable in the front-rear direction with stepped bolts. Inside the hanging piece of the holding plate, a pair of front and rear compound wheels are projectingly provided in a cantilever manner, and at the upper end of the side frame of the loading platform, a guide rail having a C-shaped cross section is opposed to the hanging piece. The double-wheels are erected upright and engaged with the guide rails so that they can travel freely. The structural feature of the second device is that the hanging piece of the wheel holding plate is wide in the first device. And the front and rear side edges thereof are located outside the outer circumference of the pair of compound wheels attached to the hanging piece.

[0005]

[Description of Drawings] In FIGS. 1 and 2, 1 is a delivery van type small freight vehicle, 2 is a loading platform, 3 is an extendable opening / closing hood, and 3 is an extendable opening / closing hood that covers a loading platform 2. 4 and a large number of hood bones 5 attached to the back surface of the hood bones 5 at predetermined intervals in the front-rear direction and extending in the width direction of the loading platform 2.
Both ends of the vehicle run on the side frame of the loading platform 2 in the front-rear direction and are opened and closed.

As shown in FIGS. 3 and 4, wheel holding plates 6 bent in an angle are attached to both ends of the hood bone 5 through stepped bolts 7 so as to be rotatable in the front-rear direction. Inside the hanging piece 8 of the holding plate 6, a pair of front and rear compound wheels 9, 9 project in a cantilever manner.

A guide rail 10 having a C-shaped cross section is erected on the side frame of the loading platform 2 so as to face the hanging piece 8 and sandwich the compound wheels 9 and 9 between the hanging piece 8 and the hanging piece 8. The compound wheels 9, 9 are engaged with the rail 10 so that they can travel freely as shown in the figure.

The hanging piece 8 of the illustrated wheel holding plate 6 is formed wide, and both side edges of the hanging piece 8 project outwardly from the outer circumferences of the compound wheels 9 and 9. In this way, when the door is opened and closed, the adjacent hood bone is closed. Since the compound wheels 9 of 5 do not come into contact with each other, it is possible to prevent the occurrence of the braking action.

In addition, 11 is a hood cloth hem holding plate, 12
Is a fastener hook (male part).

[0010]

EFFECTS OF THE INVENTION Since the trolley-bone traveling device for the expandable and retractable hood for small trucks of the present invention is as described above, the following effects can be expected. That is, when the hood bone does not move in parallel when opening and closing the hood, the wheel holding plate rotates, so that opening and closing is not hindered. The bottom of the hood cloth is not caught in the running part of the wheels, and the rainwater does not enter the loading platform because it is blocked by the guide rails. If the hanging pieces of the wheel holding freight are formed to have a wide width so that the front and rear edges thereof are outside the outer circumference of the pair of compound wheels attached to the hanging pieces, the wheels of adjacent hood bones are opened and closed when opening and closing. It is possible to prevent contact and braking.
