Description

[Detailed description of the invention] In this invention, when the handle is used, the handle, which is inserted and held in the case, protrudes to a position where it can be grasped by pressing a push button, and the handle is grasped and pulled out further from the case. In particular, it relates to a push-button flat handle device in which a latch plate behind the case rotates in conjunction with the unlocking direction.

A push-button flat handle device that uses a single leaf spring to hold the handle in its retracted state and rotate the handle in the protruding direction is disclosed in Publication of Utility Model Publication No. 50-11102.
It has already been disclosed in the publication.

However, in this flat handle device, the end of the leaf spring inserted into the spring receiver on the back of the handle and the spring receiver on the front of the back wall of the case is formed flat, so it is difficult to insert the handle into the case. While the ejection operation is repeated, the insertion end of the leaf spring partially protrudes from the spring receiving portion, and in the worst case, the leaf spring may completely fall off.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a push-button flat handle device that does not cause the leaf spring to fall off even after repeated use, and that operates stably over a long period of time.

The push button type flat handle device of the present invention will be described below with reference to the drawings. A handle 2 housed in a case 1 is pivoted to a case side wall 4 by a pivot 3, and is triggered by pressing a push button 5. A latch plate 6 that rotates in the unlocking direction by the protruding rotation of the handle 2
is pivotally attached to the rear surface of the case back wall 7, and a first spring receiver 8 and a second spring receiver 9 are respectively provided on the front surface of the case back wall 7 and the rear surface of the handle 2, which are opposite to the push button 5 with respect to the pivot 2, A first end 13 and a second end 14 of a leaf spring 12 on which sharp protrusions 10 and 11 are formed.
are inserted into the first spring receiving part 8 and the second spring receiving part 9, respectively, and the handle 2 is housed and held and urged to protrude and rotate by means of the leaf spring 12.

In this example, as shown in FIG. 3, the operating protrusion 15 of the handle 2 protrudes behind the opening 16 of the case rear wall 7 and engages with a passive hole 17 formed in the latch plate 6.

As shown in FIG. 2, a guide screw 19 is screwed into a position symmetrical to the screw 18 that pivotally connects the latch plate 6 to the back wall 7 of the case, and its head is connected to the passive hole 7.
It engages with the edge of 7.

As shown in FIG. 4, the leaf spring 12 is curved even in an unloaded state, and the first end 13 and second end 14 thereof have three continuous sharp protrusions 10, 11.
is provided.

As shown in FIG. 3, when the handle 2 is stored in the case 1, the second end 14 of the leaf spring 12 is located behind the connecting line between the first end 13 and the pivot 3. The elastic force of the leaf spring 12 is the same as the handle 2.
acts as a force that tries to rotate the clockwise direction. Therefore, the handle 2 is firmly held at the original storage position.

When the pushbutton 5 is pressed and the operating protrusion 20 of the push button 5 is pressed against the passive protrusion 21 of the handle 2, the handle 2 is rotated counterclockwise against the rotational bias of the leaf spring 12. When the second end 14 of the leaf spring crosses the connection line between the first end 13 and the pivot 3 forward, the elastic force of the leaf spring 12 rotates the handle 2 counterclockwise. It acts as a force that forces you to do something. In this way, the handle 2 that has protruded and rotated to the grippable position is further pulled out by the operator's hand, and the latch plate 6, which has been pushed against the edge of the passive hole 17 by the operation protrusion 15 of the handle 2, moves into the second position. In Figure 2, it rotates clockwise and separates from the receiving part on the housing body side. Therefore, the door to which the case 1 is attached is unlocked from the casing body.

In this way, when the handle 2 is rotated protrudingly or retracted, the leaf spring 12 is moved to the first spring receiving part 8 on the case side.
The oscillating motion and expansion/contraction motion are repeated centering on the second spring receiving portion 9 on the handle side, but in the push button type flat handle device of the present invention, the flat spring inserted into the first spring receiving portion 8 Sharp protrusions 10 and 11 are provided on the first end 13 and the second end 14 of the leaf spring inserted into the second spring receiver 9, respectively. Since it is engaged with the second spring receivers 8 and 9 in a biting state, the first end 13 and second end 14 of the leaf spring 12 are separated from the first spring receiver 8 and the second spring receiver 9. It never looms large.

That is, according to the present invention, it is possible to easily obtain a push-button type flat handle device that does not cause the leaf spring 12 to fall off unnecessarily and always operates stably.
