Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention particularly relates to a storage device for a winch hook in a winch mounted on a vehicle.

[Prior Art] Mechanical winches that are commonly used on vehicles include a winch drum that is attached to the front of the vehicle via a front bumper and a base angle fixed to the vehicle body, and is rotated using engine torque as a power source. The wire on the drum is paid out or rewound by the forward and reverse rotation of the drum. At this time, the wire is configured to be guided along a pair of vertical and horizontal guide rollers supported by a roller bracket.

[Problem to be Solved by the Invention 1] However, when such a winch is not in use, the winch hook is naturally fixed and stored, but in order to ensure proper fixation and good workability, the winch hook has already been fixed and stored. A number of storage methods have been proposed. Figures 3 and 4 are from the 1980s.
- Winch hook fixing disclosed as 28794M
This is an example of a storage device. The invented device has a winch hook having a modified U-shaped cross section with an open front surface and a fitting protrusion C that fits between two horizontal guide rollers b and b that guide a winch wire a. A storage boulder d, a fixing plate e that faces the storage holder d so as to sandwich the guide 0-ra bSb and fixes the holder d, and a storage holder d.
The winch hook f is pivotally supported in the front opening of the
A clamping plate Q that clamps the winch hook F, and a penetrating protrusion attached to the clamping plate Q that defines the neck of the winch hook f.
1, and a weld bolt j and a butterfly knot for rotatably fastening the fixing plate e to the storage holder d and the clamping plate.

However, in the above-mentioned invention $11, after temporarily tightening the storage holder d that sandwiched the hook r and the fixing plate e, and then fitting it between the guide rollers b and b and rotating only the fixing plate e, It requires a cumbersome installation procedure that requires final tightening, so it is by no means an excellent method in terms of workability. In addition, these storage elements are
l) Since it has to be kept in the location J, it has the disadvantage that it can sometimes be lost or lost.

A technical problem to be solved by the present invention is to create a hook storage device that can be permanently installed without any problem in the use of a winch, and yet has extremely good workability.

[:! Means for Solving the Problems] In order to solve the above problems, the present invention provides a roller bracket with a cross-shaped roller bracket that supports a pair of vertical and horizontal idle rollers for guiding a winch wire, and a winch wire between the upper and lower walls of the roller bracket. A support shaft that is erected to avoid interference, a saucer that is coupled to the support shaft and holds the curved part of the winch hook, and is screwed into an external thread formed on the upper half of the support shaft, A new structure is adopted, which includes a nut member that fastens the winch hook between the winch hook and the saucer.

In a preferred embodiment of the present invention, the spindle, which is arranged to avoid interference with the operating winch wire, is erected roughly outward from one of the vertical guide rollers, and the receiver is attached to the winch hook. In order to stably hold the curved portion, bent edges with dimensions commensurate with the curved portion are provided protruding at several locations on the outer periphery. Further, it is desirable that the nut member is a seated nut having a circular seat larger than the center diameter of the curved portion of the winch hook.

[Operation] Therefore, when storing the winch hook in the apparatus of the present invention, first, the curved portion of the winch hook guided along one of the vertical guide rollers is placed on the receiving tray. At this time, the wind deft hook is positioned and stably held by the bent edge. Next, by tightening the nut member using a wrench, the winch hook can be easily tightened between the receiving plates. In addition, if you set the distance between the saucer and the nut member sufficiently wide in advance,
Setting the winch hook onto the saucer can be done more easily.

When using the winch, simply loosen the nut member and quickly take out the winch hook for work.
Moreover, since the storage device including the spindle does not interfere with the operation of the winch, it can be permanently installed and accidents involving loss are eliminated.

[Example 1 Hereinafter, the present invention will be explained in detail based on the drawings.

In FIG. 1, 10 indicates only one of the roller brackets connected to the front surface of the winch drum (not shown), and also includes the other roller bracket (not shown).
These winch elements are attached to the front of the vehicle via support members such as base angles 12. To explain in more detail, the pair of left and right roller brackets 10 formed in the shape of an opening have vertical guide rollers 14 aligned with the winch drum erected at each inner front position, and furthermore, between the opposing side walls 10a are the A pair of upper and lower horizontal guide rollers 16 are connected to the drum at a position further back than the vertical guide rollers 14 (position Q). The winch wire 18 is guided by the vertical and horizontal pairs of hydraulic rollers 14 and 16,
It is configured to be fed out or rewound.

One of the roller brackets 1-10 in this embodiment is equipped with a storage device described below.
The winch wire 18 is formed with a suitable free space on the outside of the winch wire 18, that is, at a position that does not interfere with the winch wire 18 that is in operation.

As is clear from FIGS. 1 and 2, a support shaft 20 is fastened and erected between the lower walls of the free space by machine screws 22 and 22. A saucer 26 for receiving the winch hook 24 is fixed near the center of the support shaft 20.
In order to stably hold the curved portion 24a of the winch hook 24, the hook 6 has bent edges 26a having dimensions commensurate with the curved portion 24a and protruding upwardly at four locations on the outer periphery. The support shaft 20 has a thread cut in the upper half from the vicinity of the connection part of the saucer 26, and the winch hook 2 is attached to the male thread part.
The circular seat 28 is slightly larger than the center diameter of the curved portion 24a of No. 4.
A seat nut 28 having a diameter a is screwed onto the seat nut 28. Note that the bottom surface of the seat nut 28 and the top surface of the saucer 26 may be covered with a rubber sheet or the like.

This embodiment is configured as described above, and when storing the winch hook 24, first, one of the winch hooks is
Curved portion 24a of winch hook 24 guided along 4
is placed on the tray 26 in such a manner as to hold the support shaft 20 therein.

At this time, the curved portion 24a of the winch hook 24 is surrounded by the bent edge 26a which has the same dimensions and is protruded upwardly, so that positioning and stable holding are simultaneously satisfied. Of course, at this stage, the seat nut 28 is replaced by the saucer 26.
The winch hook 24 can be set without much effort. After that, by tightening the external nuts 1 to 28 in the retracted position using a wrench, the winch hook 24 can be easily fastened onto the saucer 26.

When the winch is used again, the winch hook 24 can be taken out by simply loosening the seat nut 28, so that the next winch operation can be carried out quickly.

[Effects of the Invention] As described above in detail, the present invention provides a spindle that stands up in the free movement area of the roller bracket i- that does not interfere with the operating windshield V, and wraps the curved part of the windshield on the spindle. Since the winch hook is equipped with a saucer for holding the winch hook and a nut member for clamping the winch hook, the winch hook can be reliably stored and taken out quickly with extremely easy operation. Since these storage elements do not affect the operation of the winch in any way, the device can be installed permanently and accidents such as loss can be completely eliminated.

In addition, the winch hook can be directly clamped onto the surface of the element!
In addition to improving the stability of the retracted winch hook, the one covered with an i-shock also has the effect of eliminating abnormal noises when the vehicle is running.
