Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a push-button operation device for operating, for example, a power switch of a tape recorder.

Conventionally, in this type of operating device, the lock body was formed from sheet metal, so it was flat and could not be formed thickly. Therefore, the contact area of the shaft support with the shaft was extremely small, and it did not swing in the surface direction when the operating body slid. This has the drawback that the operating body moves and comes into strong contact with the engagement pin of the operating body, making it difficult for the operating body to slide smoothly.

Therefore, the present invention provides an operating device that eliminates the conventional drawbacks and has a simplified configuration.

Specific examples of the present invention will be explained below with reference to the drawings.

In the figure, reference numeral 1 denotes an operating body, which has a push button 2 formed at its rear, a guide groove 3 in the sliding direction at its tip, and a folded piece 5 of a tension spring 4 protruding from one side edge of its tip. Furthermore, a retaining pin 6 is protruded from the tip of the lower surface, and an operating pin 7 is protruded from the rear of the lower surface.

Reference numeral 8 denotes a lock body, which is molded with resin, and the rear portion where the bearing hole 9 is formed is thick, and a raised portion 10 is formed on the outer edge of the bearing hole 9, and the upper surface of the tip portion is thick. That is, a guide portion 11 is formed on the surface facing the operating body 1.

A retaining part 11b is formed in this guide part 11 in succession to the introduction guide groove 11a, protrusions 11C and lld are provided protrudingly on both sides of the opening of this retaining part 11b, and an engaging part 11
A push-up edge surface 11e having an inclined portion is formed at the tip of the push-up edge surface 11e, and an engagement portion 11b continues from the push-up edge surface 11e.
An outlet guide surface 11 f is formed surrounding the guide groove 11 f in a U-shape and reaching the inner edge side of the introduction guide groove 11 a.

Furthermore, a folded piece 12 is provided protruding from the outer edge of the vicinity of the bearing hole 9 in correspondence with the folded piece 5 of the operating body 1 .

The operating body 1 and lock body 8 configured as described above are installed on the aircraft A.
To attach the lock body 8 to the shaft B protruding from the body A, first fit the bearing hole 9 into the shaft B so that the lock body 8 can rotate freely, then insert the operating body 1 into the guide frame C and attach it to the guide protrusion. Then, the guide groove 3 is engaged with the lock body 8, and the engaging pin 6 is introduced into the guide groove 11.
a to tension the tension spring 4 between the folded pieces 5 and 12 on both sides 1 and 8.

Then, when the operating body 1 is pushed into the lock body 8 against the biasing force of the tension spring 4, the retaining pin 6 comes into contact with the protrusion 11C from the introduction guide groove 11a of the lock body 8, and is pressed and locked. It moves while rotating the body 8 and comes into contact with the protrusion 11d.

In this state, the locking body 8 is rotated back by the biasing force of the spring 4, and the engaging part 11b is engaged with the engaging pin 6. When the pressing force of the operating body 1 is released, the engaging pin 6 is moved to the engaging part. 11b, and the operating body 1 is held in a pushed-in state.

In this state, the operating pin 7 of the operating body 1 turns on (or off) a switch (not shown).

Also, from this state, when the operating body 1 is pushed in again, the engagement pin 6
rides up on the push-up edge surface 11e of the lock body 8, and as a result of this riding-up, the locking pin 6 is released and the push-up edge surface 11e
This leads to the derivation guide surface 11f which is continuous to
When the pressure on the operating body 1 is released, the operating body 1 is returned to its original position by the biasing force of the spring 4.

At this time, the engagement pin 6 returns to the introduction guide groove 11a again through the lead-out guide surface 11f.

In the above operation, the operating body 1 is in a state where the tip side is lifted up with respect to the lock body 8 using the raised part 10 on the outer edge of the bearing hole 9 as a fulcrum, so that the engagement pin 6 is raised against the guide part 11 of the lock body 8. The operating body 1 can slide smoothly without being strongly abutted.

As described above, according to the present invention, the shaft support of the lock body is formed thickly so that the contact surface with the shaft is large, so that it does not swing unnecessarily during rotation operation, and the operating body is Since it slides in a floating state, it can slide smoothly and operability is significantly improved, allowing the operated object such as a switch to be operated reliably and smoothly.Also, it is constructed using only one spring. This has advantages such as simplification and cost reduction.
