が設けられている。As a cam member having a heart-shaped cam groove (hereinafter referred to as a heart cam), there is one as shown in FIG.
The cam groove 2 is formed on the upper surface of the heart cam 1 in the drawing, and an operation shaft 3 for sliding operation is coupled to the end surface. A pin 4 whose tip 4a slides in the cam groove 2 is provided above the cam groove 2 in a part of a casing (not shown) so that the pin 4 can swing in parallel with the upper surface of the heart cam 1. Is attached to the locking portion 5. Above the pin 4, a leaf spring 6 is provided so that the tip 4a of the pin 4 is brought into pressure contact with the bottom surface of the cam groove 2, and an intermediate portion of the pin 4 is elastically pressed toward the heart cam 1. Also, on the left side of the figure,
A spring (not shown) is provided for elastically ejecting the heart cam 1 in the direction of arrow N.

なう往復動作である。First, when the heart cam 1 is in the initial state, that is,
When the heart cam 1 is moved to the rightmost side in FIG. 6, the pin 4 is locked by the locking portion 5 provided on the housing, so that the tip 4a of the pin 4 is guided by the guides in FIGS. 7 and 8. groove
It is at position A on the tip side of 12. When the operation shaft 3 is pushed in the direction of arrow M in FIG. 6 from this position, the tip 4a is relatively moved in the direction of arrow a.
In the direction of arrow C, the slope is moved upward in the direction of arrow b through position B, reaches position C, and falls from step 7 in the direction of arrow c to reach position D. When this position is in a state of being pressed by a full stroke and the pressing force of the operation shaft 3 is released from this state, the heart cam 1 returns in the direction of arrow N by the biasing force of the spring. Then, the tip 4a falls from the D position through the step 8 in the direction of the arrow d, reaches the E position, and is locked at this position. When the operating shaft 3 is pressed again from the locked state, the tip 4a drops the step 9 in the direction of arrow e and reaches the position F. When the pressing force is released at this position, the slope is raised in the direction of arrow f and the step 10 is formed. To the G position, the step 10 is dropped in the direction of arrow g, and the introduction / outlet path is returned to the initial state position A in the direction of arrow h. This operation is specifically performed by the operation shaft 3
This is a reciprocating operation accompanied by a lock in which when the push button is pushed once, it is locked at the E position, and when it is pushed again, it returns from the E position to the A position.
上記のようなハートカム１は、例えばスイツチ装置や回

用できない場合が生じる。The heart cam 1 as described above is used, for example, in a switch device or a rotary type electronic component, and its stroke has A position and D position.
Specified by position. Therefore, in order to increase the stroke, it is necessary to increase the distance between the A position and the D position, and in order to increase the distance, it is necessary to increase the dimension of the heart cam 1 itself in the longitudinal direction. However,
If the size of the heart cam 1 is large, the left end of the heart cam 1 in the drawing contacts the end surface of the housing when the heart cam 1 is pushed by the maximum stroke, so the housing needs to be enlarged accordingly. Therefore, if the size of the housing is increased, the size of the switch device and the rotary electronic component itself is increased, the space factor is deteriorated, and it may not be applicable to a small product.

方法ではピンの製造コストが高くなるという問題があ
り、またストロークの選択に対する自由度が低いという
不都合もあつた。From such a point, for example, a heart cam 60 as shown in FIG. 9 has already been proposed.
Then, the pin 50 simultaneously contacts the tip Q of the side wall portion 52 that guides the tip of the pin to the inlet 51, and the corner R of the cam groove 53 or the corner S on the end side, whereby the tip Q is formed. Between corner R
Alternatively, the pin 50 may be fitted between the tip portion Q and the corner portion S, and the movement of the heart cam 60 may become impossible between them. Further, it has been pointed out that the distance from the introduction port 51 to the full stroke position becomes short, so that the inclination of the cam groove 53 on the introduction portion 54 side becomes tight and the operation feeling deteriorates. Among these, as a method for preventing pin tip entrapment, there is a method of using a pin having a fin portion for preventing fitting with a synthetic resin material as shown in Fig. 10. There is a problem that the cost becomes high, and there is also a disadvantage that the degree of freedom in selecting a stroke is low.
したがつて、この考案は、小型でもストロークを大きく
設定でき、しかも動作が確実でコストの安いハートカム
を用いたプツシユロツク装置を提供することを目的とす
る。Therefore, it is an object of the present invention to provide a push-lock device using a heart cam that can set a large stroke even if it is small, and operates reliably and at low cost.

もに、ロック解除状態において前記ピンの作動桿が前記
カム溝の導入・導出口から離脱しないように前記作動桿
を保持する保持手段を設けた構成にしてある。In order to solve the above problems, the present invention engages a heart-shaped cam groove of a cam member with a tip protruding portion of a pin having an operating rod portion extending from a fixed side, thereby connecting the cam member and the pin. In a push-lock device that reciprocates in the extension direction of a pin and locks it at a predetermined position, the cam member is formed so as to be continuous with the cam groove, and a protruding portion at the tip of the pin is introduced into the cam groove. An introduction / outlet port having an inclined portion to be led out is provided, and further, the length dimension in the moving direction of the cam member is formed to be small so that the tip protruding portion of the pin is separated from the cam member in the unlocked state. The holding means for holding the operating rod is provided so that the operating rod of the pin does not separate from the inlet / outlet opening of the cam groove in the unlocked state.
上記構成によると、ピンの先端がカム部材から離脱した
後も、ピンの一部が常にカム部材に形成されたカム溝の
ピン先端の導入・導出口から離脱しないので、カム部材
が作動して該先端部がカム部材の端面に至つたときに
は、常に該導入・導出口に至り、該先端部はプツシユ動
作時に間違いなくカム溝に導入される。According to the above configuration, even after the tip of the pin is disengaged from the cam member, a part of the pin does not always disengage from the inlet / outlet opening of the pin tip of the cam groove formed in the cam member, so the cam member operates. When the tip reaches the end face of the cam member, it always reaches the introduction / outlet port, and the tip is surely introduced into the cam groove during the push operation.

よりも当該逃げに相当する寸法、小さくすることができ
る。With the heart cam 13 configured as described above, the second
In the initial state of the figure, the tip 4a of the pin 4 is located in the cam groove 2
And the operating rod 4b portion of the pin 4 is separated from the guide portion 2b.
Since the pin 4 is sandwiched between the protrusions, it is impossible to swing the pin 4. When the push operation of the operation shaft 3 is performed from the initial state of FIG. 2, the introduction / outlet port 2b reaches the tip 4a of the pin 4 as the heart cam 13 moves, and the tip 4a
4a rides in the cam groove 2 and goes up the slope in the direction of arrow b in the same manner as in the conventional example, and the same operation is performed to bring about the locked state. When the bushing operation is performed again from the locked state, it gets over the step 10 and falls in the direction of the arrow g, and the introduction / outlet port 2a
From the heart cam 13 to the middle portion 4b and the guide portion 2b.
It returns to the initial position while being clamped by. Therefore, even if the introduction / outlet port 12 is omitted and the heart cam 13 is shortened, the tip 4a of the pin 4 is always introduced into the cam groove 2. Therefore, as shown in the embodiment, for example, a sufficiently large stroke can be secured without making the housing 35 of the cam portion 22 larger than necessary. That is, in the conventional case, when the full stroke has been pushed down, the escape of the guide groove 12 portion, in other words, the escape portion of the L portion shown in FIG. 7 must be provided in the housing 35. Since the L portion is unnecessary, it is not necessary to provide a relief for the L portion. Therefore, the dimension corresponding to the escape can be made smaller than the conventional one.
また、ピン４を単なるバネ用の線材によつて形成すれば
よいので、ストロークの選択も自由にでき、コストも安
くすることができる。Further, since the pin 4 may be formed of a simple wire material for spring, the stroke can be freely selected and the cost can be reduced.

も確実でコストの上昇を招くこともない。As described above, according to the present invention configured as described above, it is not necessary to provide the housing with the escape of the portion where the guide groove is formed in the conventional state in the state where the full stroke is pushed down, so the size reduction can be achieved. Can be planned. Further, by replacing the escape portion with stalk, it is possible to increase the stalk without increasing the size. At that time, since the structure of the cam groove and the operating rod itself is the same as the conventional one, the operation is reliable and the cost is not increased.
