Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a device for attaching a road board to a truck axle, and more specifically to a device for attaching a road board in an extended state on the axle in a removable manner. It is something.

[Problems to be solved by conventional techniques and ideas]

When a road board is used for the purpose of loading and unloading cargo onto a truck, the road board must be loaded onto the truck together with the cargo. Therefore, after loading the cargo onto the truck bed, the road board is stacked on top of the cargo. Therefore, when the cargo is fully loaded, or in the case of a small truck, it is necessary to stack and secure the road board on top of the cargo. is not an easy task.

The present invention was made to solve this problem, and by making use of the tilting of the truck, especially the side tilting, and installing it in an extended manner on top of the truck, the space for loading road boards on the truck can be substantially reduced. This achieved the intended purpose.

[Means for solving problems]

The present inventor first fixed a pin member extending laterally in a cantilevered manner onto a pedestal attached to the upper side of the truck gate, and also attached an L-shaped bar member movable in a direction parallel to the pin member via a spring. The L-shaped rod member is rotatably supported, and the pin member is inserted into a short pipe fixed along the girder of the road board.
A device for attaching a road board to a truck gate, characterized in that the shaped tip part elastically engages between the face materials of the road board, so that the road board can be extended over the track gate and removably attached. However, the present invention has a simple structure by using the L-shaped rod-shaped member as an engagement plate that can be inserted between the face plates of the road board in an undulating manner without using the above-mentioned elastic members such as springs. This is an improved device that is easier to maintain.

The gist of the present invention is that a road board is constructed by fixing face materials at predetermined intervals between parallel girders on a pedestal having legs that can hold the upper side of the truck gate. A pin member that can be inserted into a fixed short pipe is provided to protrude in the lateral direction, and an L-shaped eave part into which the top of the girder material of the road board can fit is provided parallel to the pin member. The present invention relates to a device for attaching a road board to a truck gate, characterized in that an engagement plate member which can be inserted in a freely undulating manner between the face members of the road board is fixed to a shaft member rotatably supported by the shaft member.

[Effect]

In carrying out the present invention, it is sufficient to use two devices for attaching the above-mentioned road boards to the truck axle in the longitudinal direction of each road board to be attached to the truck axle, but in this case, a pin member is attached to the above-mentioned pedestal. It is advantageous to use a combination of a device with both engagement plate members and a device with only a pin member on the pedestal.

〔Example〕

First, to explain the road board used in the present invention, as shown in Fig. 4, the road board is basically parallel to each other on both sides between the girder members 1, 1' and the opposing side walls of the girder members 1, 1'. It consists of face members 2 fixed at required intervals in the longitudinal direction, and both of these are made of extruded aluminum alloy members.

As shown in Fig. 1, the girder members 1 and 1' are hollow square tubular members with shelves formed on the inner surface and the outer surface open except for the upper end, rising from the inside of the bottom plate a. A lower plate b, a shelf c extending horizontally inward from the upper end of the lower plate b, a middle plate d rising from the outside of the shelf c, an upper tapered plate e rising inclined outward from the upper end of the middle plate d, and an upper side. It consists of an upper plate f that extends horizontally outward from the upper end of the tapered plate e, a hanging plate g that extends downward from the outside of the upper plate f, and a tapered end plate h that slopes inward and extends downward from the hanging plate g. An opening is formed between the lower end of the bottom plate a and the outside of the bottom plate a.

In the hollow portions of the beam members 1, 1', short pipes 3 inscribed at the intersections of the bottom plate a, the shelf plate c, and the middle side plate d are fixed by welding 4.

Next, the pedestal 5-A shown in FIG. A pair of bolt holes are provided for tightening the bolts in a tilted manner, and a bolt 7 is attached to each hole. On this pedestal 5-A, a cantilevered pin member 8 that can be inserted into the short pipe 3 of the road board girder material is provided laterally on the inside, and on the pedestal 5-A. On the outside, an L-shaped eave part 9 is provided in parallel with the pin member 8, into which the tops e, f, and g of the aforementioned road board girder members can fit, and left and right bearings 10 are mounted on this L-shaped eave part 9. , 10 rotatably supports a shaft member 11, and a bearing 1 is attached to this rotating member 11.
The engagement plate member 12 is fixed between 0 and 10.

On the other hand, the pedestal 5-B shown in FIG. 2B is exactly the same as the pedestal 5-A described above, except that it does not have the bearing 10, the shaft member 11, and the engagement plate member 12.

As shown in Fig. 5, the above-mentioned cradle 5-A and 5-B are arranged so that 5-A is on the rear side of the truck and 5-B is on the front side on the upper side of the side gate 13 which is fixed to the upright position of the truck. Each pin member 8 is fixed at a predetermined interval in the same direction as the protruding direction of the pin member 8.
-A, 5-B, hold the upper side of the gate between both legs 6, 6' and use the bolts 7, 7 to hold the cradle 5-A, 5.
- Tighten each B to the upper side.

Next, as shown in FIGS. 3 and 6, the road board 14 is placed on the cradle 5.
-A, 5-B installation procedure will be explained.

The road board 14 on which the short pipes 3 have been welded and fixed in advance to the girder members 1 and 1' at the same predetermined intervals as above is laid down, and the tops of the girder members are turned toward the outside of the truck bed 16.
3, fit the top of the lower girder 1' of the road board 14 into the L-shaped eaves 9 of the supports 5-A and 5-B, and slide the road board girder 1' in the longitudinal direction. When each pin member 8 of the cradle 5-A, 5-B is inserted into the short pipe 3 of the pedestal 5-A, the girder member 1' below the road board 14
A, on 5-B, its pin member 8 and L-shaped eave part 9
The road board is fixed in the longitudinal direction of the gate.

Next, the engagement plate member 12 of the pedestal 5-A is used to fix the road plate so that it does not move in the longitudinal direction of the gate.
is rotated and the plate member 12 is inserted into the space 15 between the face members 2.

In this state, the plate member 12 engages with the gap 15 of the road board 14, which is slightly wider than this, so the road board 14 is inserted into the short pipe 3 and the pin member 8 is inserted into the short pipe 3. The road board is fixed in both the left and right directions (lengthwise direction), so that the road board is stably held upright in an extended form on the gate.

The track board 14 is then tied to the truck load through the gap 15 of the road board 14, so that the road board 14 is tightly and integrally tightened with the cargo.

[Effect of idea]

According to the present invention, the road board is placed horizontally on the axle, and the top of the road board girder material is fitted into the L-shaped eave member of the pedestal that is fastened to the upper side of the agitation, and the pin member of the pedestal is fitted. After inserting it into the short pipe of the road board, by operating the rotatable shaft member also attached to the pedestal, the engagement plate member is inserted into the gap between the face plates of the road board. By preventing mutual movement in the longitudinal direction of the gate, the pin member and the short pipe are prevented from coming loose, and as a result, the road board can be attached and removed from the gate as if it were an extension of the gate. It has great practical value, as it can be mounted freely and stably, the road board can be set without taking up virtually any space on the track, and it can be easily attached and detached.
