Description

[Detailed description of the invention] A. Purpose of the invention (1) Industrial application field The present invention relates to a vehicle key for operating the engine main switch, door lock, etc. of automobiles, motorcycles, etc.

(2) Prior Art The above-mentioned vehicle key has a plate-shaped knob connected to the base of the key body, and anti-slip uneven parts are provided on both of the sensing surfaces of the knob, for example, as disclosed in Japanese Patent Application Laid-open No.
It is conventionally known as disclosed in Japanese Patent No. 52-146397.

(3) Problems to be solved by the invention In order to make the concave and convex portion of the knob have a high anti-slip function, it is necessary to make the convex portion high, but in that case, the thickness of the knob will increase unnecessarily. , there is a problem that not only is the appearance unsightly, but the keys are bulky as a whole.

The present invention was proposed in view of the above, and it is possible to provide an extremely high anti-slip function to a knob without causing the above-mentioned problems of conventional ones, and is particularly suitable for use in vehicles to ensure that the key can be pulled out. The purpose is to provide a key.

B. Structure of the invention (1) Means for solving the problem In order to achieve the above object, the invention combines a flat knob made of synthetic resin with the base end of the key body, and the knob has both photographing surfaces. The front half of the key body side is formed into a front downward slope, and the middle part of each slope extends linearly in a direction perpendicular to the direction in which the key is inserted and removed, and with respect to the front and rear surfaces of the middle part. A plurality of protrusions and grooves with different heights are arranged alternately, and the front and rearmost portions of the group of protrusions and grooves are grooves, and each groove is formed to cross each slope. It is characterized by

(2) Effect According to the above configuration, the fingertip that picks up the knob will first dig into the groove from the lower front and rear surfaces of the protrusion and groove group, and then touch the front and rear protrusions, so that Even if the amount of protrusion from the low surface is small, the protrusions on the front and rear parts in particular provide a strong sensation of protrusion to the fingertips, and a strong anti-slip effect is exerted when inserting or removing the key. . Furthermore, since the front half of the knob picking surface where the protrusions and grooves are formed is formed on a slope that slopes downward in the front, the fingertips exert a backward thrust on the slope, especially when pulling out the key. This makes it easier to operate the knob, and together with the anti-slip effect of the projections and grooves mentioned above, the knob can be pulled out reliably.

In particular, each of the grooves is formed so as to cross each of the slopes, so if dust or finger marks accumulate in the groove, insert the tip of a nail or the like into the groove. By simply rubbing along the slope, dust, etc. inside the groove can be easily scraped out of the slope.

(3) Embodiment Hereinafter, an embodiment of the present invention will be explained with reference to the drawings. 1 is a flat knob made of synthetic resin, and when it is molded, a connecting piece 2 formed at the rear end of the key body 2 is formed.
a is coupled to the knob 1 by implantation.

Both photographing surfaces 3, 3 of the knob 1 are formed into slopes 3a, 3a that descend toward the front in the front half on the key body 2 side, and are parallel surfaces in the rear half. Each slope 3
A plurality of protrusions 4, 4, . . . and grooves 5, 5, . In this case, each protrusion 4 is, as particularly shown in FIG.
Each groove 5 is formed higher than the slope 3a and lower than the slope 3a, and the front and rearmost portions of the protrusion 4 and the group of grooves 5 are grooves 5. In addition, each of the grooves 5 is connected to each inclined surface 3.
It extends to both end surfaces of the knob 1 so as to cross the line a.

At the rear of the knob 1, a long hole 6 for attaching a key boulder is provided, which extends parallel to the protrusion 4 and the groove 5.

According to the above arrangement of the protrusions 4 and the grooves 5, the fingertip that takes the knob 1 when inserting or removing the key will first bite into the grooves 5 from the lower front and rear surfaces of the groups of protrusions 4 and grooves 5. Next, it comes into contact with the front and rear protrusions 4, so even if the amount of protrusion of the group of protrusions 4 relative to the lower surface is small, the protrusion sensation that the front and rear protrusions 4 give to the fingertips is particularly strong. It is possible to effectively prevent the knob 1 from slipping between the knob 1 and the fingertip photographing it when inserting or removing a key.

In particular, the protrusion 4 and the groove 5 are formed.
The front half of both knob shooting surfaces 3 and 3 is a slope 3 that slopes downward in front.
a, 3a, when the key is pulled out, it becomes easier to apply a rearward thrust from the fingertip to the slope 3a, and this together with the anti-slip effect of the protrusion 4 and groove 5 mentioned above, The knob 1 can be pulled out very strongly. It should be noted that when inserting the key, the finger can be strongly pressed against the rear end surface of the knob, so that the special provision of the slopes 3a, 3a does not interfere with the inserting operation of the key.

In addition, since each groove 5 extends long to both end surfaces of the knob 1 so as to cross each slope 3a, if dust or finger marks accumulate in the groove 5, the tip of a nail or the like can be removed from the groove. 5 and simply rub it along the groove 5, the above-mentioned dust etc. in the groove 5 can be easily scraped out to the outside of the slope 3a.
In this case, it is possible to effectively prevent clogging of the concave groove 5 with dust and the like.

C. Effects of the invention As described above, according to the invention, a flat knob made of synthetic resin is connected to the base end of the key body, and the front half of the key body side of both photographic surfaces of this knob is moved forward and downward. The middle part of each slope has a plurality of protrusions and grooves extending linearly in a direction perpendicular to the key insertion/removal direction and having heights relative to the front and rear surfaces of the middle part. are arranged alternately, and the front and rearmost portions of the protrusions and grooves are made into grooves, so that the fingertip that takes the knob should first dig into the grooves from the lower front and rear surfaces of the protrusions and grooves, and then It comes into contact with the front and rear protrusions, so even if the amount of protrusion of the protrusion group relative to the lower surface is small, the protrusion sensation that the front and rear protrusions give to the fingertips is strong,
It exhibits a strong anti-slip effect when inserting or removing the key, effectively preventing slippage between the knob and the fingertips.Also, the thickness of the knob has been increased due to the special provision of the above-mentioned group of protrusions. can be kept to a minimum. Furthermore, since the front half of the knob-picking surface where the protrusions and grooves are formed is formed on a slope that slopes downward from the front, especially when the key is being pulled out, the thrust from the fingertips toward the rear against the slope is difficult. This makes it easier to operate the knob, and together with the anti-slip effect of the protrusions and grooves mentioned above, the knob can be pulled out reliably. On the other hand, when inserting the key, you can press your finger firmly against the rear end of the knob. Therefore, the special provision of the slope does not interfere with the key insertion operation.

In particular, each of the grooves is formed so as to cross each of the slopes, so if there is dust or dirt on the groove, insert the tip of a nail or the like into the groove. By simply rubbing along the grooves, dust, etc. in the grooves can be easily scraped out to the outside of the slope, and therefore, clogging of the grooves with dust, etc. can be effectively avoided on each slope. Therefore, not only can the appearance of the slope, which functions as a non-slip surface for the knob picking surface, always be maintained neatly, but also a sufficient height difference between the protrusion and the groove on the slope can always be ensured. The anti-slip effect can be effectively exhibited at all times.
