Description

The present disclosure relates to hook receiving structures.

Conventionally, hooks for towing vehicles have been put into practical use. For example, the hook is formed so that the vicinity of the base end is fixed to the vehicle, and a traction tool such as a rope is attached to the tip to pull the hook. Here, there is a demand for a hook accommodation structure that accommodates the hook so as not to hinder the running of the vehicle and the movement of the passenger.

Therefore, as a technique for housing the hook, for example, Japanese Patent Application Laid-Open No. 2002-200000 discloses a mounting structure for a tow hook that reliably prevents interference with the road surface. In this mounting structure, a recess is formed in the bottom wall of the lower member of the tow hook, and the tow hook is mounted in this recess, so that the tow hook can be accommodated without interfering with running of the vehicle.

JP-A-59-070206

However, in the attachment structure of the tow hook of Patent Document 1, since the tow hook is arranged in the recess, it may be difficult to attach a tow tool such as a rope to the tow hook. Therefore, it has been proposed to make the hook detachable from the vehicle so that it can be accommodated without changing the fixed position of the hook. As a result, the hook can be normally housed in the vehicle, and the hook can be taken out and fixed at a predetermined fixing position when the vehicle is towed. At this time, it is required to easily take out the hook accommodated in the vehicle.

SUMMARY OF THE INVENTION An object of the present disclosure is to provide a hook housing structure that allows easy removal of a housed hook.

The hook housing structure according to the present disclosure has an elongated shape, and a traction fixing portion that is screwed and fixed to a vehicle for towing is formed in the vicinity of a base end and is smaller than the traction fixing portion. A hook having a diameter and having a hook-side engaging portion that is fixed by engaging with a vehicle for storage is formed at the proximal end.

According to the present disclosure, it is possible to easily take out the accommodated hook.

Hereinafter, embodiments according to the present disclosure will be described based on the accompanying drawings.

(Embodiment 1)
FIG. 1 shows the configuration of a hook accommodation structure according to Embodiment 1 of the present disclosure. The hook accommodation structure has a hook 1 and an accommodation portion 2 .

The hook 1 is used for towing a vehicle, has an elongated shape, and has a towing fixing portion 3 formed near its base end and a connecting portion 4 formed at its tip end.

The towing fixing portion 3 is for fixing to a vehicle for towing, has a cylindrical shape, and has a male thread formed on its outer peripheral surface so as to be fixed to the vehicle by screwing. The traction fixing portion 3 is formed corresponding to the vehicle-side fixing portion of the vehicle body frame (not shown).

The connecting portion 4 is for attaching a towing tool such as a rope when towing, and a through hole for attaching the towing tool is formed in the central portion thereof.

The accommodation part 2 is for accommodating the hook 1, and can be arranged adjacent to the jack J arranged in the vehicle, for example. The housing portion 2 has a pair of side wall portions 5 a and 5 b and a bottom wall portion 6 . Side wall portions 5a and 5b have a plate shape and are arranged to face each other. Further, the bottom wall portion 6 has a plate shape and is arranged so as to connect the side wall portions 5a and 5b. The side wall portions 5a and 5b and the bottom wall portion 6 form an accommodation chamber R for accommodating the hook 1. As shown in FIG.

The housing portion 2 also has a pair of edge portions 7a and 7b projecting from the upper portions of the side wall portions 5a and 5b. The edge portions 7a and 7b have a plate shape and are formed to protrude in opposite directions. A through hole 9 is formed in the edge portion 7a, and a fitting portion M provided on the base of the jack J is fitted into the through hole 9. As shown in FIG. Further, the edge portion 7b is arranged so as to come into contact with the back plate B of the vehicle. In this manner, the edge portion 7a is fitted into the fitting portion M and the edge portion 7b is brought into contact with the back plate B, whereby the housing portion 2 is fixed to the vehicle.

Further, the housing portion 2 has a pair of support portions 8 that connect the side wall portions 5a and 5b in the vicinity of their central portions in the vertical direction. The pair of support portions 8 are arranged to face each other with the accommodation chamber R interposed therebetween. As a result, the postures of the side walls 5a and 5b are supported.

With such a configuration, the accommodating portion 2 can be easily manufactured. Specifically, the plate member is bent into a U shape to form the side walls 5a and 5b, and the ends thereof are further bent to form the edges 7a and 7b. Then, the accommodating portion 2 can be produced by fixing the support portion 8 to the side wall portions 5a and 5b by welding or the like.

Next, the configuration of the hook 1 and the accommodation portion 2 will be described in detail.

As shown in FIG. 2 , the hook 1 has a hook-side engaging portion 10 at its proximal end, and a diameter-reduced portion 11 is formed between the towing fixing portion 3 and the hook-side engaging portion 10 . .

The hook-side engaging portion 10 has a diameter smaller than that of the traction fixing portion 3 and is formed so as to engage with and be fixed to the accommodating portion 2 . Here, the hook-side engaging portion 10 is formed so as to be fixed to the accommodating portion 2 by screwing. Specifically, the hook-side engaging portion 10 has a columnar shape protruding from the base end portion of the hook 1 and has a male thread formed on its outer peripheral surface to be screwed into the accommodating portion 2 . As a result, the hook 1 is fixed to the vehicle via the housing portion 2 .

The reduced-diameter portion 11 is formed in a truncated cone shape so as to gradually reduce in diameter from the fixing portion 3 for traction toward the hook-side engaging portion 10 , and the surface thereof is inclined toward the central axis of the hook 1 . face is formed.

On the other hand, the housing portion 2 has a housing side engaging portion 12 that engages with the hook side engaging portion 10 on the bottom wall portion 6 . The receiving side engaging portion 12 is arranged on the surface of the bottom wall portion 6 opposite to the receiving chamber R, and has a female thread formed in the center thereof to be screwed with the hook side engaging portion 10 . A through-hole is formed in the bottom wall portion 6 at a position corresponding to the hook-side engaging portion 10, and the housing-side engaging portion 12 is screwed into the hook-side engaging portion 10 protruding from this through-hole. Thus, the hook 1 is fixed to the accommodating portion 2. As shown in FIG. The housing-side engaging portion 12 can be configured from, for example, a nut.

Further, the side walls 5a and 5b are formed with a width corresponding to the towing fixing portion 3 of the hook 1. As shown in FIG. As a result, the side walls 5 a and 5 b guide the base end of the hook 1 to the receiving side engaging portion 12 . Thus, the sidewalls 5a and 5b constitute the guides of the present disclosure.

The side walls 5a and 5b also have an inclined portion 13 that is inclined corresponding to the reduced diameter portion 11 of the hook 1. As shown in FIG. The inclined portion 13 is formed so as to incline from the side walls 5 a and 5 b toward the through hole of the bottom wall portion 6 at the same angle as the reduced diameter portion 11 . As a result, the inclined portion 13 guides the proximal end portion of the hook 1 to the accommodation side engaging portion 12 . Thus, the inclined portion 13 constitutes the guide portion of the present disclosure.

Next, the operation of this embodiment will be described.

First, as shown in FIG. 3, when accommodating the hook 1, the hook 1 is inserted into the accommodating chamber R of the accommodating portion 2 with the proximal end portion leading. At this time, the side wall portions 5a and 5b are formed with a width corresponding to the traction fixing portion 3 of the hook 1. As shown in FIG. As a result, the hook 1 is aligned on the same central axis as the housing-side engaging portion 12 along the side walls 5a and 5b and guided to the housing-side engaging portion 12. As shown in FIG.

In this way, the side wall portions 5a and 5b are formed with a width corresponding to the tow fixing portion 3 of the hook 1, so that the hook side engaging portion 10 can be smoothly guided to the accommodation side engaging portion 12. can.

Further, as shown in FIG. 4 , the sidewalls 5 a and 5 b are formed with inclined portions 13 , so that the base end of the hook 1 is guided to the receiving side engaging portion 12 along the inclined portions 13 .
Thus, by forming the inclined portions 13 on the side walls 5a and 5b, the hook side engaging portion 10 can be smoothly guided to the housing side engaging portion 12. As shown in FIG.

Then, when the hook-side engaging portion 10 comes into contact with the accommodation-side engaging portion 12, the hook 1 rotates around its own central axis in the fixed direction. Thereby, as shown in FIG. 2, the hook side engaging portion 10 is screwed into the housing side engaging portion 12, and the hook 1 can be fixed to the housing portion 2. As shown in FIG.
At this time, since the hook-side engaging portion 10 is formed at the proximal end portion of the hook 1 , the hook 1 can be easily fixed to the accommodating portion 2 without interfering with the work of accommodating the hook 1 .

Further, since the hook side engaging portion 10 is formed to be fixed to the housing side engaging portion 12 by screwing, the hook 1 can be firmly fixed to the housing portion 2 .
Further, since the hook 1 is fixed so that the diameter-reduced portion 11 is fitted to the inclined portion 13 while being in contact with the inclined portion 13 , the hook 1 can be firmly supported by the accommodating portion 2 .

Thus, the hook 1 can be stably fixed by being housed in the housing portion 2 .
The accommodation portion 2 can be formed at such a low height that the hook 1 falls down when the hook-side engaging portion 10 is not screwed to the accommodation-side engaging portion 12 . As a result, if the hook side engaging portion 10 is not screwed after the hook 1 is inserted into the accommodation chamber R, the hook 1 falls down, so the user does not screw the hook side engaging portion 10. can be noticed, and the hook 1 can be reliably fixed to the housing portion 2.例文帳に追加

In this way, as shown in FIG. 1, when the hook 1 is housed in the housing portion 2, the vehicle is driven in that state. At this time, since the edge portion 7a is fitted to the fitting portion M and the edge portion 7b is in contact with the back plate B, the housing portion 2 is reliably supported by the vehicle, and the hook 1 is stabilized. can be fixed.

Subsequently, when the vehicle is towed, the hook 1 is rotated in the direction opposite to the fixing direction, and the hook-side engaging portion 10 and the housing-side engaging portion 12 are disengaged from each other.

Here, it is conceivable that the hook 1 is fixed to the housing portion 2 using the towing fixing portion 3 during housing. That is, it is conceivable to provide a threaded portion corresponding to the securing portion 3 for traction in the accommodation portion 2 and to fix the securing portion 3 for traction to the accommodation portion 2 by screwing the securing portion 3 for traction into this threaded portion. However, in general, the towing fixture 3 is formed with a relatively large diameter, such as M24, in order to withstand the load during towing. For this reason, the hook 1 must be rotated with a large force in order to unscrew the towing fixing portion 3 , and there is a risk that much labor will be required to remove the hook 1 from the accommodating portion 2 .

Therefore, in the present disclosure, a hook side engaging portion 10 having a diameter smaller than that of the tow fixing portion 3 is formed at the proximal end portion of the hook 1, and this hook side engaging portion 10 is screwed into the housing side engaging portion 12. Let Therefore, the hook 1 can be rotated with a small force to release the hook-side engaging portion 10 from the screw engagement, and the hook 1 accommodated in the accommodation portion 2 can be easily removed. At this time, the hook side engaging portion 10 is preferably formed with a diameter that can be easily removed by many users, and can be formed with a size of M8, for example.

In this way, when the hook 1 is removed from the housing portion 2, it is fixed to the vehicle-side fixing portion F provided on the vehicle body frame V as shown in FIG. The vehicle-side fixing portion F has a screw hole H formed with a female thread corresponding to the towing fixing portion 3. By screwing the towing fixing portion 3 into the screw hole H, the hook 1 is attached to the vehicle. It is fixed to the side fixing part F. At this time, the vehicle-side fixing portion F is formed so as to pass through the screwing hole H, and the hook-side engaging portion 10 is inserted into the screwing hole H together with the towing fixing portion 3 .
In this way, since the hook-side engaging portion 10 is formed at the base end portion of the hook 1, the hook 1 can be easily fixed without interfering with the work of fixing the hook 1 to the vehicle during towing. .

Then, when the hook 1 is fixed to the vehicle, a traction tool such as a rope is attached to the connecting portion 4 of the hook 1, and the vehicle is towed by a towing vehicle or the like.
At this time, since the hook 1 is firmly fixed to the vehicle-side fixing portion F by the towing fixing portion 3 formed with a large diameter, the hook 1 can easily withstand the pulling force for pulling the vehicle.

According to this embodiment, since the hook-side engaging portion 10 is formed at the proximal end portion of the hook 1 with a diameter smaller than that of the tow fixing portion 3, the housed hook 1 can be easily removed. .
