Description

[Detailed Description of the Invention] <Industrial Application Field> The disclosed technology belongs to the technical field of devices for holding spare tires of automobiles.

Therefore, this invention provides a spare tire locking device that allows the spare tire held on the lower surface of the vehicle body frame to be removed by a detachable tool inserted through an insertion hole formed in a cross member of the vehicle body. In particular, a stopper member is removably attached to a position that cuts off a tool insertion path including an insertion hole in a cross member, and the stopper member is prevented from coming off when the door panel is closed. This invention relates to a spare tire locking device.

<Prior Art> As is well known, automobiles are equipped with a spare tire in case of an emergency, and a holding device for the spare tire is provided.

For example, in passenger cars, a spare tire is generally fixed in the trunk or bonnet.

However, in the case of trucks, one-box cars, etc., due to space considerations, for example,
As disclosed in Japanese Utility Model Application No. 55-50836, Japanese Utility Model Application No. 51-45758, Japanese Utility Model Application No. 56-385, Japanese Utility Model Application No. 58-107974, etc., the spare tire is held on the underside of the vehicle body frame. Many of the types that do this are used.

In addition, in the spare tire holding device, since the spare tire is held on the outside of the vehicle body, it must be particularly securely locked.

<Problem to be solved by the invention> However, regarding the spare tire holding device based on the prior art, for example, Japanese Utility Model Application Publication No. 55-50836, Japanese Utility Model Application Publication No. 51-45758, and Japanese Utility Model Application Publication No. 51-45758 are disclosed. The type disclosed in Publication No. 385 and the like had a drawback in that mud and the like adhered to the locking parts such as bolts and locks, making it difficult to lock and unlock smoothly.

Furthermore, in the device disclosed in Japanese Utility Model Application Publication No. 58-107974, the holding part is covered with a spare tire, which prevents mud etc. from adhering to the holding part, but it is difficult to lock the holding part. There was a problem.

On the other hand, in an embodiment in which a locking mechanism is provided inside the holding portion, the structure becomes complicated, which has the disadvantage of increasing costs.

For example, Japanese Utility Model Publication No. 57-39250 discloses a technology in which a spare tire anti-theft device is provided and a bumper can be opened and closed to the door to allow the spare tire to be attached and detached. Since the bumper as an absorbing member can be opened and closed, if the bumper is damaged, it becomes impossible to attach or remove the spare tire, and since the heavy bumper is sandwiched between the door and the floor If the bumper resonates due to vibration, abnormal noise will be generated, and there is also a risk that abnormal noise will be generated due to rattling due to installation errors.

Furthermore, since the sealing material of the door is brought into contact with the bumper, there are disadvantages such as poor sealing performance.

The purpose of this invention is to solve the problems of the spare tire locking device based on the above-mentioned conventional technology as a technical problem, and to create a system that is capable of reliably locking and unlocking the held spare tire, has high reliability, and has a simple structure. It is an object of the present invention to provide an excellent spare tire locking device that is useful in the application field of vehicle body equipment technology in the automobile industry.

<Means for Solving the Problems> In order to solve the above-mentioned problems, the structure of this invention, which is based on the above-mentioned claims for utility model registration, is based on the insertion of a spare tire attachment/detachment tool held on the underside of the vehicle body frame. A spare tire locking device in which a hole is formed in a vehicle body member, wherein a stopper member is removably provided in a position that cuts off an attachment/detachment tool insertion path including the insertion hole in a cross member of the vehicle body; A holding part for holding the lower end of the stopper member is fixed in the cross member, and the lower end of the door panel when the door is closed is at the upper end of the stopper member. This is a spare tire locking device that comes at an equal or shorter height.

<Function> When the spare tire is to be held on the underside of the car body frame, the spare tire attachment/detachment tool is inserted through the tool insertion hole formed in the cross member of the car body, and the spare tire is held on the underside of the car body. Then, after removing the attachment/detachment tool, a stopper member is attached to a position that cuts off the attachment/detachment tool insertion path including the insertion hole of the cross member, and the spare tire holding device is locked. The measures were taken.

<Example> Next, an example of this invention will be described below based on the drawings.

The embodiment shown in FIG. 1 is a truck 2 having a chassis frame equipped with a hanging type locking device 1 of this invention. A spare tire 4 is attached to the lower surface and can be removed.

As shown in FIGS. 2 and 3, a rocker panel 5 and a back door 6 are provided at the rear of the truck 2, and the lower side of the joint 8 of the door panels 7, 7 of the back door 6 is provided as a vehicle body member. A cross member 9 having a square cross section is provided.

A spare tire 4 is mounted on the front and rear surfaces of the cross member 9.
Holes 10, 10 into which a jacking arm 3 as an attachment/detachment tool is inserted are formed, and an insertion path 11 for the jacking arm 3 is formed in a space connecting each hole 10.

A bolt 12 serving as a stopper member is inserted from above at the upper part of the cross member 9 and at a position where the insertion path 11 is cut off.
It is adapted to be screwed into a weld nut 14 of a bracket 13 having a silk hat-shaped cross section which is fixed to the bottom wall of the cross member 9.

As shown in FIG. 4, the length of the bolt 12 is equal to or slightly longer than the distance between the upper surface of the bracket 13 and the lower end of the joint 8 of the door panel 7.

Further, a flange 15 for guiding the head of the bolt 12 is provided on the upper surface of the cross member 9 to which the head of the bolt 12 is locked, while a pipe 16 is fixedly extended on the upper surface of the bracket 13 to secure the bolt. 12
covers the bottom of the

Even if the bolt 12 comes out of the weld nut 14, it will not come off the cross member 9.

In the above configuration, when the spare tire 4 is attached to the lower part of the vehicle body frame, the jacking arm 3 is first inserted into the hole 10 of the cross member 9 from the rear side to hold the spare tire 4 on the lower surface of the vehicle body frame. After that, the jack arm 3 is removed and the back door 6 is opened.

Then, insert the bolt 12 into the cross member 9 from the upper surface of the cross member 9 with the back door 6 open, and tighten the tip of the bolt 12 to the weld nut 14 with a wrench to create the state shown in FIG. The path 11 is cut off by the bolt 12, and the back door 6 is closed and locked.

In this case, for example, even if a third party tries to loosen the bolt 12, the head of the bolt 12 will be damaged by the flange 15.
When the tool is turned, the back door 6 etc. will become too tight due to the relationship between the length of the bolt 12 and the height of the back door 6, so it cannot be loosened.
Even if it were possible to loosen it to the state shown in the diagram,
Since the pipe 16 is fixed to the bracket 13, as long as the back door 6 is closed, the bolt 12 will not come off by tilting or pulling it up, and the insertion path 11 will remain cut off. , it is not possible to insert other jack arms.

Further, by adjusting the length of the bolt 12 so that it comes off the weld nut 14 just before it hits the joint 8 of the door panel 7, it is possible to prevent damage to the door panel 7 etc. even if the bolt 12 is forcibly turned.

In this way, the lock can be reliably secured, and when the occupant wants to remove the spare tire 4, he or she opens the back door 6, removes the bolt 12 using a hub nut trench, etc., and attaches the jack arm 3 to the cross member. What is necessary is to insert it through the hole 10 of 9 and remove it.

It goes without saying that the embodiment of this invention is not limited to the above-described embodiment, and for example, the stopper member is not limited to a bolt, and various other embodiments can be adopted.

<Effects of the invention> As described above, according to this invention, an excellent effect is basically achieved in that the spare tire can be locked and unlocked reliably.

Further, an insertion hole for a spare tire attachment/detachment tool held on the lower surface of the vehicle body frame is formed in a cross member of the vehicle body, and the stopper member is positioned in a position to cut off an insertion path for the attachment/detachment tool including the insertion hole of the cross member. Since it is removable, it can be locked and unlocked smoothly even if it gets muddy, and the structure is simple, so it does not break down and can be manufactured at low cost. be done.

Furthermore, since the cross member is attached to the vehicle body frame when the vehicle body is assembled, there are few installation errors, there is no rattling or abnormal noise caused by vibration, and the cross member is highly durable.

In addition, unlike locks, they do not require a key or the like and have the advantage of being easy to lock and unlock. Since the cross member is fixed with a holding part that holds the lower end of the stopper member, even if the stopper member is disengaged from the cross member, it will not tilt or be removed from the cross member of the vehicle body. There is.

In addition, since the height from the engagement part of the cross member with the stopper member to the door panel is set to be equal to or shorter than the removal length of the stopper member, the stopper member cannot be removed from the cross member of the vehicle body. You can get double the effect that will never be lost.
