Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a key top case mounted on a key top of a key plate.

(Prior Art) FIG. 5 is an exploded perspective view of a key top case of a conventional key plate.

In the figure, 1 is a key plate and 2 is a key top of the key plate 1.

With respect to the key top 2 of such a key plate 1, a key top case body 5 provided with a light emitting element 3, a switch 4, a lighting means including a battery (not shown), and the key plate 1 is attached to the key top case body 5. A key top case composed of a key top case cover 6 attached so as to be sandwiched is attached so that the key plate 1 can be easily inserted into the key hole even at night.

As shown in FIG. 5, a concave portion 6a into which the key top 2 is fitted is formed on the key top facing surface of the key top case cover 6 of this key top case, for example.

By the way, in such a key plate 1 for an automobile,
Some are 2.0 mm thick and some are 2.3 mm thick.

Therefore, when using the key plate 1 having a thickness of 2.0 mm, the sheet 7 having a thickness of 0.3 mm is used for the key top case cover 6
The key plate 1 is set in the recess 6a to prevent the key plate 1 from rattling.

(Problems to be solved by the invention) However, such a key top case of the key plate 1
When assembling 5, 6 without setting the thickness of the key plate 1, set the key plate 1 with a thickness of 2.3 mm and assemble it.
There is a problem that the key top case cover 6 is not assembled properly and the cap top case body 5 or the cap top case cover 6 is damaged.

On the other hand, if the 2.0 mm-thick key plate 1 is set without setting the sheet 7, backlash may occur between the key top case body 5 and the key top case cover 6, and the operability. However, there is a problem that is worse.

The present invention has been made in view of the above problems, and an object thereof is to damage a mobile case, to cause looseness between the key top case and the key plate, or to deteriorate operability. It is to provide a key top case of a key plate that can prevent such a situation.

(Means for Solving the Problems) According to the present invention for solving the above problems, the key top has a long and thick recess inside which can accommodate the key top of the thick key plate, and when the key top is mounted on the short key plate, ,
By using a spacer located in the recess and abutting against the key top, the backlash in the longitudinal direction of the key plate is removed, and when the key top is attached to a thin key plate, the key top is stacked with a sheet for adjusting the thickness. In the key top case of the key plate, which eliminates play in the thickness direction of the plate, the spacer is provided with a gauge hole for discriminating the thickness of the key plate.

(Operation) In the key top case of the key plate of the present invention,
The thickness of the key plate can be determined by inserting the key plate into the gauge hole of the spacer before setting the key plate. And if the key top is thin,
When installing the key top case, stack the thickness adjustment sheet on the key top.

(Embodiment) FIG. 1 is an exploded perspective view showing a main part of an embodiment of the present invention. In the figure, in the key top case cover 6, there is formed a recess 6a into which the key top 2 of the long type cap plate 1 can be fitted in the longitudinal direction (the direction of arrow A) with substantially no space. Then, in the recess 6a, three protrusions 6b arranged so as to be orthogonal to the longitudinal direction are formed. The position where the protrusion 6b is formed is selected so that it can be brought into contact with the base end surface 1a of the intermediate type key plate 1 and can be inserted into the key holder hole 2a of the long type key plate 1.
The key top case cover 6 is also provided with a key holder hole 6c for the key top case. Reference numeral 8 denotes a spacer that can be housed in the recess 6a while being fitted to the protrusion 6b and that can be brought into contact with the base end surface 1a of the key plate 1 when the key top case is mounted on the short type key plate 1. When the key top case is mounted on the long type and intermediate type key plates 1, the spacer 8 is not used, and when it is mounted on the short type key plate 1, the spacer 8 is used.

In addition, the spacer 8 is provided with a gauge hole 8a for discriminating the thickness of the key plate. The width A'of the gauge hole is selected so that a 2.0 mm thick key plate can be inserted and a 2.3 mm thick key plate cannot be inserted.

Further, the key plate fitting recess may be provided on one of the key top facing surfaces, or may be provided on both sides at a depth of half. Since this embodiment is an embodiment in which the recess is provided in the key top case cover, FIG. 1 shows only the key top case cover side.

Next, the mounting state of the key top case will be described. First, before setting the key plate 1, it is determined whether the key plate 1 can be inserted into the gauge hole 8a. If it can be inserted into the gauge hole 8a, a 0.3 mm thick sheet (not shown) is set in the recess 6a of the key top case cover 6, and the key plate 1 is placed on the sheet and assembled.

If the key plate cannot be inserted into the gauge hole 8a, the sheet is not used and the assembly is performed.

Next, when it is attached to the long type key plate 1, as shown in FIG. 2, the protrusion 6b provided in the recess 6a of the key top case cover 6 is inserted into the key holder hole 2a of the key plate 1. ing. Also, when it is mounted on the intermediate type key plate 1, as shown in FIG.
Touches the base end surface 1a of the key plate 1. On the other hand, when it is attached to the short type key plate 1, as shown in FIG. 4, the spacer 8 is fitted to the protrusion 6b, and the spacer 8 contacts the base end surface 1a of the key plate 1.

According to this structure, the thickness of the key plate 1 can be determined only by checking whether the key plate 1 can be inserted into the gauge hole 8a of the spacer 8. Therefore, when the thick key plate 1 is set, the key top case is not forcibly assembled, and the key top case can be prevented from being damaged.

Also, when setting the thin key plate 1,
It is possible to prevent play of the key plate and deterioration of operability.

Furthermore, in this embodiment, the short type key plate 1
When the spacer 8 is mounted on the key plate 1, the spacer 8 abuts the base end surface 1a of the key plate 1 to prevent the key plate 1 from slipping inward, and when mounted on the intermediate type key plate 1, the protrusion 6b Abuts on the base end surface 1a of the key plate 1 and inhibits the key plate 41 from slipping inward. Further, when the key plate 1 of the long type is mounted on the key plate 1, the key tops 2 of the key plate 1 are fitted in the recesses 6a with substantially no gap in the longitudinal direction, so that the key tops 2 do not slip inward. Therefore, the long-type, short-type, and intermediate-type key plates 1 do not slip inward.

Further, according to the above configuration, the protrusion 6b is formed in the recess 6a, and in the case of the short type key plate 1, the spacer 8 is further provided.
Since it is a structure using, the structure is simple, no trouble is involved in assembling, and the cost can be reduced.

(Effects of the Invention) As described above, according to the present invention, the key top has a long and thick recess for accommodating the key top of the thick key plate, and when the key top is attached to the short key plate, By using a spacer located in the recess and abutting against the key top, the backlash in the longitudinal direction of the key plate is removed, and when the key top is attached to a thin key plate, the key top is stacked with a sheet for adjusting the thickness. In the key top case of the key plate that removes the play in the thickness direction of the plate, by providing the spacer with a gauge hole for determining the thickness of the key plate, before setting the key plate, the gauge hole of the spacer By inserting the key plate into the, you can easily determine the thickness of the key plate, damage the key top case, It is possible to realize a key top case of a key plate that can prevent looseness between the key plate and operability.
