Description

Technical Field

[0001] The present invention relates to a latching support fitting for the loading platform of a truck, and more particularly to a latching support fitting used for preventing load collapse or preventing the floating of the load when fixing a load on the floor surface of a light truck or the like.

Background Art

[0002] Conventionally, a latching hook has been provided on the floor surface of the loading platform of a light truck, and the load is fixed using the latching hook. However, if the latching hook is attached to the floor surface of the loading platform, it may interfere with the loading and unloading of goods, or when the floor surface is slid to load and unload goods, the load may get caught on these latching hooks, and the load may be damaged.

[0003] Regarding this problem, the invention of Patent Document 1 has been proposed for the truck loading platform support fitting. That is, a mounting substrate for attaching to the loading platform of a truck, the floor surface of a container, etc. is formed to project at the upper end of a short cylindrical casing, the inside of the short cylindrical casing is partitioned vertically by a partition plate, the rod portion of the latching fitting is dropped into and inserted through the through hole formed in the partition plate, and the rod portion is supported in a non-removable manner by a nut, a pin, etc. Thus, the latching fitting does not interfere during the loading and unloading operations of goods, and is convenient for fixing the load by pulling out the latching fitting during the load hanging operation using a rope, a wire, etc. A support fitting has been proposed. The invention according to Patent Document 2 is a cargo bed structure of a truck configured by attaching a cargo bed to a vehicle body. The cargo bed includes a cargo bed floor for loading goods and a silk cross member fixed to the lower surface side of the cargo bed floor and installed to extend in the vehicle width direction. A fixture for fixing the cargo bed to the vehicle body is housed in the silk cross member together with a hook, and it is possible to engage another member with the hook through an opening provided in the cargo bed floor. The "silk cross member" referred to in Patent Document 2 is a long member having a substantially "C" - shaped or substantially hat - shaped cross - sectional shape, and a plurality of them are installed at predetermined intervals in the vehicle longitudinal direction so as to be substantially parallel. The silk cross member is installed on the lower surface side of the cargo bed floor so as to extend in the vehicle width direction, and since it forms a closed cross - section with the cargo bed floor, a hollow space extending in the vehicle width direction is formed between the silk cross member and the cargo bed floor.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, since the support fitting according to the invention of Patent Document 1 is supported on the floor surface in a non - removable manner, it does not serve as a means for preventing damage to the loaded goods, and there is a problem that it cannot be firmly fixed to the truck floor depending on the shape of the loaded goods. Further, although the cargo bed structure according to Patent Document 2 solves the problem of preventing damage to the loaded goods, since the receiver of the support fitting is at the bottom of the through - hole, there is a problem that it is difficult to attach and detach the support fitting.

[0007] In view of such problems, an object of the present invention is to provide a detachable latching support fitting for ropes, wires, etc.

Means for Solving the Problems

[0008] In order to solve the above problems, a latching support fitting according to the present invention is a latching support fitting attached to through holes provided near the corners at both left and right positions of a loading platform surface of a truck having a hollow structure, where a floorboard and a pair of longitudinal joists arranged in the front-rear direction on the lower surface of the floorboard are provided at appropriate intervals in the front-rear direction. The latching support fitting includes an upper support plate, a lower support plate, and a connecting member. The upper support plate has a disc shape and supports a latching fitting detachably at its center. The lower support plate is characterized in that its upper surface abuts against the lower surface of the upper support plate and is connected by sandwiching the edge of the through hole of the truck loading platform with the connecting member.

Effects of the Invention

[0009] According to the latching support fitting of the present invention, an attachment, which is a latching fitting, can be selected according to a desired use, and a desired article, such as a bicycle or a box, can be easily attached or detached.
