Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a rope hook device for a truck loading platform.

[Conventional technology]

In general, the rope hook device for a truck bed is a recess on the side plate of the truck bed or a C-shaped cross section, as introduced in volume 14 of the Sankaido edition of Jidosha Optical Zenshodai, "Vehicle body structure of trucks and buses." A hook piece having a hook part is welded, and a rope is hooked to the hook part of the hook piece to fix the load.

However, recently it has been discovered that it is not desirable for both safety and appearance quality to have the hook protruding from the side plate all the time, so when the hook is used to hang a rope, the hook protrudes, and at other times the hook is retracted. A movable rope hook device has been proposed (see Japanese Patent Laid-Open No. 131338/1983).

To explain the outline of such a movable rope hook device, when the hook piece is pushed, the hook piece moves and retracts into the device body and is stored roughly along the top surface of the side plate of the loading platform, and maintains this storage position. Next, when the hook piece in the storage position is pushed, the hook piece moves upward and protrudes from the top surface of the side plate to reach the use position.The use position is maintained, and in this use position, the rope can be hung on the hook part of the hook piece. It was made so that it could be done.

[Problem that the invention attempts to solve]

By the way, in the case of such a movable rope hook device, there is a risk of malfunction if mud, water, or dust enters the device body where the hook piece moves up and down and the hook piece moves back and forth. There is. In order to prevent this mud from entering, it is possible to insert a sealing grommet between the loading platform side plate and the hook piece, or a sealing grommet between the hook piece and the main body, but this is not possible. Another problem arises in that the hook piece becomes difficult to operate.

Therefore, the object of this invention is to provide a rope hook device that does not have the above-mentioned problems.

[Means for solving problems]

In order to achieve this object, this invention provides a main body attached to the inside of the side plate of the loading platform with a hook piece that can be moved up and down and has a hook portion between a use position protruding from the top surface of the side plate and a storage position roughly along the top surface of the side plate. In the rope hook device of the loading platform,
Even when the hook piece is in either a use position where the hook part is exposed or a stored position where the hook part is hidden, the cover part that covers the advancing and retracting part with respect to the main body is suspended below the loading platform side plate of the hook piece. This is what I did.

〔Example〕

In the figure, 1 is a loading platform side plate, 2 is a device body attached to the inside of this side plate 1 via a bracket 4, and 6 is a hook piece.

This hook piece 6 is constructed using a latch 7a etc. which is pivotally supported by a fixed shaft 7 built into the main body 2. Its operation is done by pushing the upper part of the hook piece 6 downward from above once from the state shown in Fig. 2 to move the hook piece ₆ downward and actuating the latch 7a as shown in Fig. 3. and the hook piece 6 is moved downward. Next, the latch 7a is activated again by pushing the upper part of the hook piece 6 that has moved downward again from above, and when the hook piece 6 moves upward again due to the force of the spring, it is latched at the corner 6d. 7a is rotated to make it vertical, and the hook piece 6 protrudes as shown in the fourth figure. When the upper part of the hook piece 6 is pushed downward from above again, the protrusion _6c2 of the hook piece 6 rotates the latch 7a and tilts it as shown in Figure 5. When the hook piece rises again by the force of the spring 6, the corner part 6d is latch 7a
It hooks and returns to its original position as shown in the second figure. That is, the so-called push-on-push-release mechanism, which is well-known to those skilled in the art and whose function is activated by pressing twice, is used in a position in which it protrudes from the upper surface 1a of the side plate 1, as shown by a solid line, and in a two-dot chain line. It can be moved up and down to a storage position roughly along the upper surface 1a of the side plate shown. To move from the use position to the storage position, it is activated by pushing the hook piece 6 from above, and it is held in the storage position, and to move from the storage position to the use position, it is activated by pushing the hook piece 6 again from above, It is adapted to be held in the position of use.

The hook piece 6 has a hook part 6a for the rope 8 formed at its upper end, and an actuation rod 6b that moves forward and backward with respect to the main body 2 is provided in a protruding manner. 1
A cover portion 6c that covers 0 is integrally suspended downward.

This cover portion 6c covers the advancing/retracting portion 10 even when the hook piece 6 is in either the use position or the storage position.

Therefore, when the hook piece 6 is pushed to the use position or storage position, there is no loss in operability. Furthermore, since the cover portion 6c prevents mud, water, and dust from entering the advancing/retracting portion 10, malfunctions will not occur.

Moreover, in this embodiment, the lower edge 1 of the hook portion 6a
2 protrudes slightly from the upper surface 1a of the side plate 1 by a dimension l in the use position, so that the coating on the upper surface of the side plate 1 is not damaged by the rubbing of the rope 8, and the appearance quality is further improved. It is also advantageous in terms of rust prevention.

[Effect of idea]

As described above, this invention has the advantageous effects of being able to prevent malfunctions of the device due to mud and water and ensuring stable operability.
