Description

[Detailed Description of the Invention] This invention relates to a hook for a luggage vehicle having a plurality of hooks on the loading platform.

Conventionally, when tightening cargo loaded onto a cargo vehicle,
This is done using ropes or wires, but since these ropes expand and contract, there is a risk that the load may collapse.

In the present invention, the above-mentioned load tightening is performed using a non-expandable checker 7, without the risk of the load collapsing, and the hook of the luggage vehicle and the checker 7 can be connected reliably and easily. Moreover, the present invention provides a load tightening hook consisting of a chain hook main body which can freely adjust the length of the chain.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The cargo fastening hook of the present invention will be explained below with reference to the drawings.

In the figure, reference numeral 1 denotes a hook main body which is a part of a cargo fastening hook. As shown in FIG. 2, the opening of the center line in the thickness direction of the bent front part 1a is bent so as to exhibit an inclination angle θ of about 30 to 35 degrees with respect to the center line A in the thickness direction of the main body 1, and this bent front part Luggage car A to 1a
An engagement hole 2 for engagement with the hook B is provided.

An insertion hole 4 is formed on the non-bending side of the main body 1 to allow the load tightening chain 3 to pass therethrough, and the insertion hole 4 is opposite to the retention hole 2. Che73
An elongated chain engaging hole 5 is formed so as to be located in the direction of the tensile force, continuous with the insertion hole, and closed to the periphery of the hook main body 1.

The lateral spacing D of the locking holes 5 is formed to be slightly larger than the material diameter D2 of the single link 3a in the chain 73.

Further, on the outer periphery of the locking hole 5 in the main body 1, the front width direction spacing p3 of the links 3a is provided on both the front and back surfaces of the main body 1.
A notch 6 is provided which is large in size and gradually becomes deeper from the outer circumferential side to the locking hole 5 side, and the locking hole 5 is
When locking, as will be described in detail later, a portion of each link adjacent to the link 3a inserted into the locking hole 5 engages with the notch 6, causing the link 3a to move freely. The link 3a is held in a fixed state without causing any damage, and the chino 3 can be firmly and stably locked in the locking hole 5.

Further, on the side opposite to the locking side of the main body 1 of the chino 3,
A loop-shaped hook part 8 is provided by folding back the end of the chino 3 and tying the folded part with a clamp 7.

In FIG. 3, A is a luggage vehicle, and hooks B are provided at several locations at the bottom of a loading platform C, and luggage is loaded onto the loading platform C.

In addition, E in the figure is a load tightening machine like a Cheno block, and it has hooks F and F on both sides.

The load-fastening hook of the present invention has the above-described structure, and by using a plurality of these hooks, a cargo vehicle can be
This is to tighten the cargo loaded on the truck, and specifically, it is done as follows.

First, the free end side of the chino 3 is inserted into the insertion hole 4 of the hook main body 1, and then, as shown in FIG. a link b inserted into the hole 5 and adjacent to the link a;
, c, at least the side link b inserted into the insertion hole 4 is plunged into engagement with the notch 6 to lock the free end side of the chino 3 to the main body 1.

In this case, by selecting an arbitrary chain link 3a and locking it in the locking hole 5, the effective length of the chain link 3 can be freely adjusted.

Next, using a plurality of sets of hook main bodies 1 to which the chino 3 is fixed, the engagement holes 2 of each main body 1 are opened as shown in FIG.
The bent front part 1a is directed toward the lower center of the automobile A, and the non-bent side of the main body 1 is engaged with a suitable hook B of the automobile A so as to follow the side wall of the cargo platform C.

After that, the chains 3 that are fixed to each set main body 1 are hung on the luggage rack of the loading platform C, and each chain 3 is
The hooks 8 are engaged with the hooks F of the load tightening machine E, and the load tightening machine E tightens the chenos 3 to tighten the cargo.

The chino 3 has a loop-shaped hook 8 at one end.
It is also possible to use a suitable single link a in the cheno 3 as the hook part 8 and connect it directly to the load tightening machine E without providing a special one.

Further, in the embodiment of the present invention, a notch 6 is provided, and by providing such a notch 6, the single link 3a of the chino 3 can be firmly and firmly fitted into the locking hole 5, and stably. However, even if the notch 6 is not provided, each chain 3 can be tightened without slack by the load tightening machine E, so the single link 3a in the chain 3 can be locked The link 3a can be fixed to the hook main body 1 by being locked in the stop hole 5.

Therefore, the cutout portion 6 is not essential to the present invention.

As explained above, the load tightening hook of the present invention uses a non-expandable load tightening chain and the hook main body to tie down cargo vehicles, so it can securely and firmly secure the load. During load tightening work, the hook body can be easily connected to the hook by engaging the engagement hole of the hook body with the hook of the luggage vehicle, and the hook body can be easily connected to the hook, and the hook body can be easily connected to the hook through the insertion hole of the hook body. The length of the hook is adjusted by inserting the opposite end of the hook from the hook into the load tightening machine and locking the hook in the locking hole of the hook main body. The main body and the cheno can be easily connected, and furthermore, after the hook main body is latched to the hook, the load can be tightened easily, reliably, and strongly by the load tightening machine. It can be done.

Further, since the locking hole is formed in a closed shape in the direction of the pulling force of the chain against the periphery of the hook main body, there is no possibility that the chain will separate from the locking hole when the chain is tensioned. Moreover, since the hook main body is bent at the middle portion, it can be easily and firmly locked onto the hook.
