Description

  The present invention relates to a seat loading device for a truck loading platform for loading a seat on a loading platform of a truck.

Conventionally, seating on a truck bed is generally performed manually by a person, using a fixing device such as an overhead crane, or using an additional device for a truck.
For manual work by a person, the operator has a folded truck seat, climbs on the luggage or truck carrier / side, spreads the truck seat and hangs it on the luggage, then gets off the truck and uses a rope, rubber belt, etc. The truck seat is fixed to the loading platform.
Work with a fixing device such as an overhead crane attaches the truck seat to the overhead crane (using wires), lifts it once, moves it to the truck bed, and lowers it. ing.
The work with the additional device to the truck is done by attaching the additional device for seating to the truck in advance and using the rails attached to the side of the truck, the mast with the truck seat (track like a accordion between the masts) The seat is attached.) The seat is widened, the seat is hung on the truck bed, and the mast is fixed to the bed using a rope or a rubber belt. (See Patent Document 1)

JP-A-5-50859 (Pages 2-4, FIG. 1)

Manual work by humans takes time and becomes unstable work of the scaffolding, which causes safety problems such as a fall accident.
In addition, work with a fixing device such as an overhead crane requires a large-scale device, which is costly and requires a truck to be moved to the periphery where the equipment can be used, resulting in poor work efficiency. There is also a problem that an operator who can operate the overhead crane is also required.
In addition, the additional device to the truck requires one additional device (dedicated sheet, sheet device, etc.) for each truck, and there is a problem that the cost is further increased.

    The present invention has been made in order to solve the above-described problems. A seat for a truck bed that can be seated on a truck bed with good workability and safety without cost. The purpose is to obtain a hanging device.

In the seat loading device for the truck bed according to the present invention, an L-shaped sheet holding arm configured to hold and rotate the sheet hung on the truck bed, and a U-shape directly engaged with the side surface of the truck. has a shape, by moving forward the track side from the rear of the truck the sheet holding arm holding the sheet fixed to the own device, comprising a row cormorants body apparatus sheet hanging in the track bed, the body The apparatus includes a wheel that travels on the side surface of the track and an arm fixing portion that fixes a sheet holding arm holding a sheet at a predetermined position.

As described above, the present invention has an L-shaped sheet holding arm that is configured to hold and rotate a sheet hung on a truck bed, and a U-shaped shape that directly engages a side surface of the track. and, by moving forward the track side from the rear of the truck the sheet holding arm holding the sheet fixed to the own device, comprising a row cormorants body apparatus sheet hanging in the track bed, the main unit, the track Since it has an arm fixing part that fixes a wheel that travels on the side surface and a sheet holding arm that holds a sheet at a predetermined position, the sheet hooking device to this truck bed is not an additional device added to each truck, Since it can be carried independently of the truck, it can be used for multiple trucks anywhere, and from the operator's loading platform for seating It is possible to prevent a fall accident.

Next, a method for placing a sheet on the truck bed will be described with reference to FIG.
First, the U-shaped main unit 1 is attached to the side and rear of the track. The L-shaped arm 2 is fixed to the main unit 1 while the L-shaped arm 2 is laid down, and the seat 7 is attached to the fixed L-shaped arm 2. The handle 3 is rotated until the L-shaped arm 2 reaches 90 degrees, and the L-shaped arm 2 is fixed with the L-shaped arm fixing bracket 4 as shown in FIG.
Next, while holding the handle 5 and using the wheels 6 of the main unit 1, the seat 7 is hung on the truck bed while moving from the side of the truck and from the rear to the front.
Finally, the L-shaped arm 2 is removed from the L-shaped arm fixing bracket 4 and the main unit 1. Further, the sheet 7 is removed from the L-shaped arm 2, and the sheet 7 is fixed to the track. The sheet 7 is fixed to the track by using a rubber band attached to the sheet 7.

According to the first embodiment, the main device is not an additional device added to each track, but can be carried independently of the track, and can be used anywhere.
Ordinary track seats can be used.
Moreover, since an operator does not have to climb on the loading platform, a fall accident can be prevented.
Furthermore, it is not necessary to use a large apparatus such as an overhead crane.
Further, since there is no need to use an additional device for a track, a single device can handle a plurality of tracks, thereby reducing costs.
