Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a key for an automobile, such as an automobile, in which a knob portion is tilted.

(Prior Art) Conventionally, an automobile intended to improve the safety of the entire driver's cab by providing a shock absorbing action to the key itself in order to prevent a part of the driver's body from hitting the key and being injured due to a vehicle accident or the like. As a tilt key for use,
There is something like that shown in the issue.

That is, as shown in FIG. 5, a boss portion 6a is provided at the end of the key body 6 itself, and the shaft 8 is inserted into the bearing portions 7a, 7b provided on the knob portion 7 of the boss portion 6a. The key body 6 and the knob portion 7 are rotatably connected.

Further, a gap is provided between the end surface of the key body 6 and the cutout end surface 7c of the knob portion at the connecting portion.

(Problems to be solved by the invention) However, in the structure shown in FIG. 5, the limit for tilting the knob portion 7 is that the knob portion 7 and the key body 6 are connected only by the shaft 8. There is a problem that the load becomes small and the knob portion 7 is rotationally tilted by a slight external force. For this reason, there is a problem that the knob portion 7 is easily tilted at the time of key operation which is originally performed on a daily basis, and the operability of the key is deteriorated due to wobbling of the key or the like.

(Means for Solving Problems) The present invention is intended to solve the above problems, and as a means thereof, a key body and a hinge portion are provided at an end of the key body. A tilt portion for a vehicle, wherein the knob portion is formed so as to be rotatable around the hinge portion, the end portion of the key body has a continuous shape with the knob portion, A mold part made of a resin material is provided, and the end surface of the mold part and the end surface of the knob part made of the resin material are brought into contact with each other and connected through a pin, and both contact surfaces are formed flat. Is.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view of a tilting key for an automobile according to the present invention,
2 is a front view of the state in which FIG. 1 is assembled, and FIG.
FIG. 4 is a cross-sectional view taken along the line II of FIG. 4, and FIG. 4 is a side cross-sectional view of FIG. 2 with the knob portion tilted.

In FIG. 1, 1 is a key body of a tilting key A for an automobile, 2
Indicates a knob portion. The key body 1 is made of metal, and a quadrangular prismatic mold part 3 made of a resin material is provided at an end of the key body 1. The end surface 3a of the mold portion 3 that is in contact with the knob portion 2 is formed flat, and the left and right side surfaces 3b and 3c thereof have insertion holes 3d and 3e (not shown) into which the pins 4 and 5 can be inserted. No) is provided.

The mold part 3 is arranged in a notch groove 2a provided at one end of the knob part 2, which is also made of a resin material, and pins 4, 4 are provided on bearing parts 2b, 2c provided at both sides of the notch groove 2a. 5 is pivotally supported. For the pivotal support of the mold portion 3 to the knob portion 2, the pin 4 is inserted into the insertion hole 2e formed in the bearing portion 2b,
Further, insert into the insertion hole 3d of the mold portion 3, then insert the pin 5 into the insertion hole 2f formed in the bearing portion 2c, and further insert into the insertion hole 3e (not shown) of the mold portion 3. Done by Here, the end surface 2d of the cutout groove 2a, which is the contact surface of the knob portion 2 with the mold portion 3, is formed flat like the end surface 3a of the mold portion 3.

Here, the end surface 3a of the mold part 3 and the end surface 2d of the cutout groove 2a are contacted and connected to each other, and when a force exceeding the lateral limit load is applied to the knob part 2, the contact surfaces of both are elastically connected to each other. The knob portion 2 is deformed and tilted to the side, and is finally positioned on the upper surface 3f of the mold portion 3 (see FIGS. 3 and 4).

Next, the operation of this embodiment will be described.

In the tilting key A for an automobile configured as described above, the key body 1 and the knob portion 2 are normally abutted and connected to each other with a flat abutment surface, so that the knob portion 2 can be used as an ignition key or the like without wobbling. Can be used.

On the other hand, in the event of an emergency such as an accident, the abutting surfaces are elastically deformed mutually due to the impact applied to the knob portion 2 and the end surface 2d of the knob portion 2 is deformed.
It is possible to prevent the driver from getting over the corners of the end surface 3a of the mold portion 3 and tilting the knob portion 2 to the side, which may cause the driver to come into contact with and be injured.

(Effect of the invention) As described above, in the present invention, the key body and
A tilting key for an automobile, comprising: a knob portion connected to an end portion of the key body via a hinge portion, the knob portion being rotatably formed around the hinge portion, at an end portion of the key body. A mold portion made of a resin material, which is continuous with the knob portion, is provided, and the end surface of the mold portion and the end surface of the knob portion made of the resin material are brought into contact with each other via a pin, and both contact surfaces By making each of them flat, it is possible to give an appropriate load because the knob part tilts, so when using this car tilt key as an ignition key etc. on a daily basis, it never wobbles. As a result, there is an excellent effect that the operability of the key can be improved. Also, by forming a continuous shape with the knob portion at the end of the key body and providing a mold portion made of a resin material,
Since the end of the key body and the knob are always continuous in shape, there is an excellent effect that the key can be used without any discomfort. Further, since the key body and the knob portion can be easily connected by simply bringing the end surfaces into contact with each other and attaching the pin, there is an excellent effect that the assembling workability of the key is improved.
