Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a blocking device used in a shift lever operation part of a torque converter indicator of an automobile.

[Conventional technology]

In the past, various types of blocking devices have been proposed for the shift lever operation part of the torque converter indicator of automobiles.
As shown in Publication No. 10445 (first conventional example),
A plurality of slide plates whose lengths gradually become smaller toward the top are slidably stacked together, a lever insertion hole is formed in the shortest slide plate at the top, and the top slide plate is removed. An opening is formed in each slide plate, the length of which gradually decreases as it reaches the top, and a downward protrusion is provided at the front and rear ends of each opening, which shifts into the lever insertion hole of the uppermost slide plate. The lever is inserted.

In addition, as shown in Japanese Patent Application Laid-open No. 59-220420 (second conventional example), the front and rear of each slide plate is Some have an upward protrusion at the end.

Furthermore, conventionally, Utility Model Application Publication No. 57-131335 (No. 3
As shown in the prior art example), there is also one in which upward protrusions are provided at the front and rear ends of an intermediate slide plate having a lever insertion hole, and downward protrusions are provided at the inner ends of the front and rear slide plates.

[Problem that the invention attempts to solve]

In the first conventional example, a plurality of slide plates are overlapped in order of size from below, and protrusions are provided downward at the front and rear ends of the opening, so when this is attached to the main body, the slide There is a gap between the main body and the sliding plate at the front and rear of the plate, and coins and other objects may get stuck inside and interfere with operation.

In addition, the second conventional example solves the problems of the first conventional example, but since the protrusions are provided upward at the front and rear ends of the slide plate, the protrusions are separated from each other. Dust and foreign matter tend to accumulate between the
These are difficult to remove.

Furthermore, in the third conventional example, since three sliding plates are engaged, the sliding distance becomes long and the installation space becomes large.

The present invention aims to solve the above-mentioned problems. It does not create gaps at the front and rear ends of the slide plate, allows dust and foreign matter on the top surface to be easily removed, and has a long overall length. The purpose is to prevent this from happening.

[Means for solving problems]

The blocking device of the present invention has a plurality of slide plates whose lengths are sequentially increased toward the top, which are slidably stacked together, and a lever insertion hole is formed in the bottom slide plate, and a lever insertion hole is formed in the bottom slide plate. An opening is formed in each slide plate, except for the slide plate of , whose length increases sequentially as it goes upward, and the upper front edge and the upper rear edge of each opening are tapered upwardly and backwardly, respectively. A surface is formed.

[Effect]

This invention moves each slide plate in the front-back direction in conjunction with each other by moving the lever inserted into the lever insertion hole of the bottom slide plate in the front-back direction.
Further, dust and foreign matter adhering to the upper surface of each slide plate are removed through the tapered surface of each protrusion.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 to 4.

Reference numeral 1 indicates a blocking device, and a plurality of slide plates 2a, 2b whose lengths are sequentially increased toward the top.
...2g are slidably superimposed, and a lever insertion hole 3 is formed in the center of the lowermost slide plate 2a, and each slide plate 2b, 2c except the lowermost slide plate 2a... 2g, rectangular openings 4b, 4c whose lengths gradually increase as they go upward in the front-rear direction (left-right direction in the figure)...
4g are formed, and each opening 4b, 4c...4
a protrusion 5b having tapered surfaces facing upwardly forward and upwardly rearward at the upper front edge and upper rear edge of g;
5c...5g is provided.

Reference numeral 11 denotes a main body of a torque converter indicator for an automobile, and an upper frame 12, a lower frame 13, and an intermediate frame 14 provided between the upper frame 12 and the lower frame 13 of the main body 11 have a rectangular window hole 15 in the front-rear direction. ，
16, 17 are formed, and each window hole 15, 16,
A shift lever 18 is inserted through 17.

Then, the upper frame 12 and the intermediate frame 1 of the main body 11
The above-mentioned closing device 1 is disposed between the lever insertion hole 3 of the lowermost slide plate 2a and the openings 4b, 4c...4g of each slide plate 2b, 2c...2g above this. The shift lever 18 is inserted therethrough.

Further, an indication window hole 19 is formed on one side of the window hole 15 of the upper frame 12 of the main body 11, and this indication window hole 1
An indicator board 20 is attached to the indicator 9, and marks 21 such as 1st gear, 2nd gear, drive, neutral, reverse, and parking are displayed on this indicator board 20.

Then, when the shift lever 18 is moved forward (to the left in the figure), the lowermost slide plate 2a moves forward, causing the upper slide plate 2b to move together, and each slide plate 2b, 2c... …2
The protrusions 5b, 5c...5g of g sequentially open the openings 4c, 4d of the slide plates 2c, 2d...2g above them.
... Each slide plate 2a engages with the front edge of 4g,
When 2b...2g are sequentially shifted forward and the shift lever 18 is moved forward (to the right in the figure),
In the same manner, each slide plate 2a, 2b...2g is sequentially moved backward, and each slide plate 2a, 2b...
2g, the window hole 15 which is the transition space of the shift lever 18 is always closed.

At this time, as shown in FIG.
Since it is in contact with the lower surface of the window hole 15 in , there is no gap between the main body 11 and the slide plate 2g.

Furthermore, even if the protrusions 5b, 5c, . . . 5g of each slide plate 2b, 2c, .

Note that the tapered surface portions of the protrusions 5b, 5c, . . . , 5g of each of the slide plates 2b, 2c, .

That is, when the plate thickness A of each slide plate 2b, 2c...2g is 1, the protrusions 5b, 5c...5g
The thickness B from the bottom surface is 2 to 2.4, the height C from the bottom surface of the lower part of the tapered surface 6 is 0.6 to 0.8, the protrusion 5b,
5c...Length D of 5g is 2 to 4, protrusions 5b, 5c
...the length E from the outer end of 5g to the upper end of the tapered surface 6 is 0.8 to 1, the radius of curvature F of the inner and outer apex of the protrusions 5b, 5c...5g is 0.2 to 0.3, and the tapered surface The angle α of the outer downwardly tapered surface 7 of 6 is 15°.

In addition, as shown in FIGS. 5 and 6, each slide plate 2b except the bottom slide plate 2a,
By providing reinforcing ribs 9b, 9c...9g reaching above the intermediate frame 14 at the lower front and rear ends of 2c...2g, the strength of the slide plates 2b, 2c...2g is increased, and hot air rising from below or from above Due to the heavy load of the slide plates 2b, 2c...
2g can be prevented from being deformed.

[Effect of idea]

According to the present invention, there is no gap between the front and rear ends of the slide plate, and even if dust or foreign matter adheres to the top surface, it can be easily removed by the tapered surface of the protrusion, and the overall length is also increased. It can be formed into a small size without any problems.
