Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a rope hook device for hooking a load fixing rope on the loading platform of a transport vehicle such as a truck.

(Prior Art) Conventional rope hook devices of this type generally have a rope hook that projects outward in a downward hook shape and is fixed to the side of the floor plate of the loading platform or the top of the flap plate ( For example, see Utility Model Application Publication No. 53-84820).

However, with such a structure, a loader or a passerby may get their clothes caught on the rope hook, or the rope hook may touch and injure a passerby while the vehicle is running, or the rope hook may come into contact with another object and cause injury. There is a risk of damage to the vehicle, and there are disadvantages such as spoiling the overall appearance of the vehicle.

For this reason, there are some models in which a rope hook is installed inside the tilt plate (for example, see Japanese Utility Model Application Publication No. 51-47111). There are drawbacks such as the rope hook touching the cargo and damaging it, and when a large amount of cargo is loaded, it is difficult to hook the rope to the rope hook.

(Purpose of the invention) The present invention was made to eliminate such drawbacks of the conventional technology. When in use, by pushing open the lid, a space is formed around the rope hook, and a rope is hung on the rope hook. In addition, when not in use, the lid body closes on its own using a biasing means such as a spring, thereby closing the above space, eliminating unevenness on the surface of the loading platform, and preventing human bodies from touching the rope hook. It is an object of the present invention to provide a rope hook device for a transport vehicle that can eliminate the risk of other objects getting caught.

(Structure of the invention) The present invention forms a concave portion at a suitable location on the loading platform of a transport vehicle, protrudes into the recessed portion with a rope hook whose tip end surface is substantially aligned with the surface of the loading platform, and connects the tip end surface of the rope hook with the loading platform surface. A lid body capable of closing the space between
Further, the present invention is characterized in that a biasing means is provided between the loading platform and the lid for biasing the lid in a direction to close the space.

(Example) Hereinafter, an example of the present invention shown in the accompanying drawings will be described.

In Fig. 5, reference numeral 1 denotes a loading platform for a small truck, which includes a floor plate 2, fixed side flaps 3 erected on both sides of the floor plate 2, and a rear end of the floor plate 2 that can be opened and closed in the vertical direction. It consists of a rear flap plate 4 which is freely hinged.

The side flap plate 3 includes a side plate 3a and a side plate 3a.
It consists of a horizontal upper piece 3b that is connected to the upper end and faces inward of the loading platform 1, and a hanging piece 3c that hangs down from the inner end of this upper piece 3b.

A plurality of rope hook devices 5 are provided along the longitudinal direction of the upper piece 3b of the side flap plate 3 at appropriate intervals.

As shown in FIGS. 1 to 4, from the upper piece 3b of the side flap plate 3 to the side plate 3a and the hanging piece 3c.
A rectangular recess 6 that opens upward and on both left and right sides is cut out.

The bottom wall 6a and both side walls 6b, 6b of the recess 6 are attached to hooks whose ends are fixed to the lower surface of the upper piece 3b and whose center portions are bent downward to have the same shape as the recess 6. It is formed by plate 7.

A slight gap d is formed between the hook mounting plate 7 and the side plate 3a and hanging piece 3c of the side flap plate 3.

At the center of the bottom wall 6a of the recess 6, there is a tip surface 8.
A is located on the same horizontal plane as the upper surface of the upper piece 3b of the side flap plate 3, and is a horizontal attachment part connected to the lower end of the rope hook 8, which has a head part 8b having a T-shaped side surface. 8c is fixed.

Reference numeral 9 denotes a pair of front and rear lids for closing the space between the end surface 8a of the rope hook 8 and the surface of the side flap plate 3, and in this embodiment, each lid has an upper piece 9a and Side pieces 9 hanging down from both sides
It consists of b.

The base end of the upper piece 9a is connected to each side wall 6 in the recess 6.
b is pivotally attached to the upper part of the rope hook 8 with a shaft 10 in the left and right direction, and the free end of the upper piece 9a has a notch into which the front half or the rear half of the head 8b of the rope hook 8 can fit. 11 is formed.

Further, a portion of each of the left and right side pieces 9b is inserted into a gap d between the hook mounting plate 7, the side plate 3a, and the hanging piece 3c.

Thus, as shown in FIGS. 2 to 4, in each lid body 9, the upper piece 9a is the upper piece 3b of the side flap plate 3.
The lid can be rotated around the shaft 10 between a closed position, which is located on the same horizontal plane as the lid, and an open position, where the free end is pushed down, as shown in FIG.

A coiled spring 12, which is a biasing means for the lid 9, is wound around the middle part of the shaft 10, and each lid 9 is constantly biased toward the closed position by this coiled spring 12. .

When the lid body 9 reaches the closed position, each side piece 9b
The lid body 9 is stopped by stopper pieces 9c, which are connected to the lower edges of the free ends and which face inward from each other, abut against the lower surface of the bottom wall 6a.

When the lid 9 reaches the open position, the free end of the upper piece 9a comes into contact with the upper surface of the attachment part 8c of the rope hook 8, and the lid 9 stops. A pair of elastic engagement pieces 13 made of leaf springs are respectively provided on the lower surface of the upper piece 9a of the rope hook 8 and the upper surface of the attachment part 8c of the rope hook 8.
a and 13b engage with each other, and the lid body 9 is held in the open position against the biasing force of the coiled spring 12.

In addition, 9d bulges each side piece 9b of the lid body 9 so that it becomes flush with the surface of the side plate 3a and the hanging piece 3c of the side flap plate 3 within a range that does not interfere with opening and closing of the lid body 9. This is the bulging surface.

Since this embodiment has the above-described configuration, when the rope hook 8 is not in use, by keeping both lids 9 in the closed position, the surface of the loading platform 1 is free from unevenness and has a smooth appearance. At the same time, there is no fear that the human body or other objects will be caught on the rope hook 8.

If you want to use the rope hook 8, push down the free ends of both lids 9, as shown in FIG.
All that is required is to rotate both lid bodies 9 to the open position.

Then, both the elastic engagement pieces 13a and 13b engage with each other, and the lid body 9 is restrained in the open lid position.
Even if the user releases the lid 9 after that, the lid 9 will not accidentally return to the closed position.

In this state, a rope (not shown) can be hooked below the head 8b of the rope hook 8 to tie up the cargo (not shown) on the loading platform 1.

After the rope has been hung, both elastic engagement pieces 13a,
If the free end of each lid body 9 is pulled up slightly until the engagement of the coil spring 13b is released, then the coiled spring 12
Due to the urging force, the lid body 9 immediately returns to the closed position.

(Modification) In the above embodiment, the rope hook device 5
For example, the rope hook device 5 can be placed on the side end of the floorboard 2 by laying it horizontally at 90 degrees, or by rotating it by 180 degrees and facing downward. It may also be provided at the lower end of the tilt plate 3.

Furthermore, the rope hook is not limited to the T-shape as in the embodiment, but may also be a rod bent into an L-shape or other shapes.

(Effects of the invention) As is clear from the above, according to the invention, when in use, by pushing open the lid, a space is formed around the rope hook, and a rope can be hung on the rope hook, and when not in use. Sometimes, the lid body is closed to its original position by the biasing force of the biasing means, thereby closing the space and eliminating the unevenness on the surface of the loading platform, eliminating the risk of a human body or other objects getting caught in the rope hook. It is extremely convenient.

In addition, in the present invention, the rope hook itself is not moved out of the loading platform, but the lid that closes the space around it is opened and closed, so the rope hook can be firmly fixed to the loading platform. It has the advantage of being strong.
