JPS60964Y2 - Towing and tie-down hook - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a towing/tie-down hook that is used by being attached to the frame of an automobile or the like.

Conventionally, this type of towing/tie-down hook is made by bending a rod-shaped body into a planar annular shape, and bending both ends of the hook body into a side shape, as disclosed in, for example, Japanese Patent Application Laid-Open No. 54-54001. The hook body is welded to a diagonally downwardly extending surface of a bracket, and the annular portion of the funk body protrudes diagonally outwardly and downwardly.

In this case, since only both ends of the hook body are welded to the bracket, the strength is weak, and when tie-down for towing or shipping, the hook at the end of the rope or chain is attached to the annular part of the hook body. When hooked, depending on the direction in which the rope, etc. is pulled, the hook body may deform and its protrusion angle may vary, and the welded part may come off. Also, if the rope, etc. is pulled inward during tie-down, There was a risk that the tip end hook would slide up along the annular portion of the hook body, and the rope or the like would damage the skirt portion of the vehicle body.

In view of these points, the present invention increases the overall strength,
This prevents the hook main body from accidentally bending or coming off, and prevents the end hook of a rope or the like from slipping up even if the hook is hooked onto the hook main body and pulled inward. To provide a traction and tie-down hook that can be used safely without damaging a skirt part, etc.

The towing/tie-down hook of the present invention includes a bracket that is attached to a frame, a base plate having a mounting hole for the frame, a reinforcing wall formed by bending the periphery of this base board almost vertically downward, and The hook body is composed of a hook body reinforcing wall formed by extending one side of the wall further downward, and the hook body that engages the hook is composed of an annular part formed by bending the middle part of a rod-shaped body into an annular shape, and a hook body reinforcing wall formed by extending one side of the wall further downward. and a mounting portion formed at both ends of the hook body, the hook body is formed into a sideways shape by bending the mounting portion, and the mounting portion of the hook body is attached to the base plate of the bracket. The hook is fixed to the lower surface of the hook body, and the middle part of the annular part is fixed to the tip of the reinforcing wall of the hook body.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 is a bracket, and the planar shape is a S゛ triangular board 11.
, a reinforcing wall 12 formed integrally with the board 11 by bending the peripheral part of the board 11 vertically downward, and a reinforcing wall 12 formed by extending the reinforcing wall part toward the - side further downward. The walls 13, 13 are formed by mounting holes 14, respectively, in portions corresponding to the apexes of the triangle of the substrate 11.
. . , and a pair of protrusions 15° 15 are provided on the lower surface of the center of the substrate 11.

Note that the protrusions 15, 15 may be provided by cutting and raising a part of the substrate 11.

Reference numeral 2 is the hook body, and the annular part 2 is formed by bending the middle part of a rod-shaped body so that the planar shape becomes annular, and then bringing both ends of the rod into close contact with each other in parallel, and bending the whole body so that the side shape becomes a U-shape.
1 and a rear end mounting part 22 formed by closely contacting both ends of a rod-shaped body in parallel, and the mounting part 22 is bent so that the side surface shape of the whole is in the shape of a square. .

Then, attach the attachment portion 22 of the hook body 2 to the projection 15.1.
5 and fixed to the lower surface of the center of the board 11 by welding or the like, and by fixing the middle part of the annular part 21 to the tips of the hook body reinforcing walls 13, 13 by welding or the like,
It serves as a tow and tie-down hook.

According to the above configuration, the three mounting holes 14 provided in the base plate 11 of the bracket 1 can be used to attach the bracket to the lower surface of the vehicle body, etc., via a mounting tool such as a bolt (not shown). As a result, the towing/tie-down hook can be installed in an extremely stable state with no wobble in the front, rear, left, or right directions using the minimum necessary number of bolts and other mounting tools.

In addition, since the reinforcing wall 12 is integrally provided around the entire circumference of the board 11, the strength of the board 11, that is, the strength of the bracket 1 can be increased. A strong bracket 1 can be manufactured easily and at low cost.

In particular, the rear end attachment part 22 of the hook body 2 is fixed to the center part of the lower surface of the base plate 11 by welding, etc., and the intermediate part of the annular part 21 is fixed by welding, etc. to the tip part of the hook body reinforcing walls 13, 13. Since the board 11 and the hook body reinforcing wall 13 are fixed together,
, 13 and the hook main body 2 are combined in a triangular shape on the side, and it is possible to obtain a hook with very high strength.

Therefore, as shown by the two-dot chain line in FIG. Needless to say, when pulling in the direction of arrow A,
Even when the hook body 2 is pulled in the direction of arrow B that intersects with the protruding direction, the hook body 2 will not come off unexpectedly or bend and its protruding posture will change, and the hook body reinforcing wall 13 .13, there is no fear that the hook 31 will slide up along the annular portion 21, and the engagement posture of the hook 31 with respect to the hook body 2 can be ensured with good stability. (not shown) is eliminated, and safety during tie-down can be improved.

Further, as described above, if the protrusions 15.15 are provided on the lower surface of the board 11, it is possible to easily position the rear end attachment part 22 of the hook body 2 when fixing it by welding or the like, and the hook body 2 can be easily positioned on the board. 11 can be accurately fixed at a predetermined position, workability during fixing can be improved, and quality can be improved.

As explained above, according to the present invention, it is possible to efficiently attach it to a vehicle body, etc., and it has excellent strength.
The hook body does not come off unexpectedly or bend, and has the advantage of being highly durable.

In addition, during tie-down, the hook at the end of the rope or chain can be prevented from shifting, and safety can be improved, which is an excellent practical effect.
