In this design, the latch plate behind the case is interlocked in the unlocked direction as the handle stored in the case protrudes into a position where it can be released by the push button's push operation, and the handle is drawn out further from the case. It relates to a push-button plane handle device that rotates.

A pushbutton type plane handle device which maintains the handle state of the handle and the rotational force in the protruding direction of the handle by a single leaf spring has already been disclosed in Japanese Laid-Open Patent Publication No. 50-11102.

However, in this flat handle device, the spring receiving portion and the leaf spring inserted into the spring receiving portion on the front surface of the case back are formed flat on the handle back, so that the immersion operation and the protrusion operation of the handle to the case are repeated. In the meantime, the insertion end of the leaf spring partially escapes from the spring housing portion, and in the worst case, the leaf spring may be completely removed.

Accordingly, an object of the present invention is to provide a push button type flat handle device that does not drop off of a leaf spring even by repeated continuous use and operates stably over a long period of time.

Referring to the following drawings, the push-button flat handle device of the present invention rotatably attaches and pushes the handle 2 stored in the case 1 to the case side 4 by a pivot 3. In response to the pressing of the button 5, the latch plate 6, which rotates in the unlocking direction by the protruding rotation of the handle 2, is pivotally installed on the rear surface of the case back wall 7, and the push button is pressed against the axis 3 above. The first spring receiving portion 8 and the second spring receiving portion 9 are respectively provided on the front surface of the case back wall 7 and the handle 2 on the opposite side of the case 5, and the sharp projections 10, 11 are provided. The first end portion 13 and the second end portion 14 of the leaf spring 12, which are formed in the upper end portion 12, are inserted into the first spring receiving portion 8 and the second spring receiving portion 9, respectively. By (12), the storage space of the handle 2 and the protruding rotational force are made.

In this example, as shown in FIG. 3, the operating protrusion 15 of the handle 2 projects rearward from the opening 16 of the case back wall 7, and is provided with an operation hole provided in the latch plate 6. 17).

As shown in FIG. 2, in the symmetrical position with the vis 18 for pivotally attaching the latch plate 6 to the case wall 7, the guide vis 19 is screwed in and its head is operated. It is coupled to the edge of the hole 17.

As shown in Fig. 4, the leaf spring 12 is curved even under no load, and three sharp edges 10 and 11 are provided on the first end 13 and the second end 14 in succession.

As shown in FIG. 3, when the handle 2 is accommodated in the case 1, the second end 14 of the leaf spring 12 is positioned behind the connecting line between the first end 13 and the shaft 3. Since it is located, the elastic force of the leaf spring 12 acts as a force to rotate the handle 2 in the clockwise direction.

Thus, the handle 2 is held in the original storage position.

Pressing the push button 5 and pressing the driven protrusion 21 of the handle 2 with the actuating protrusion 20, the handle 2 stands against the rotational bias by the leaf spring 12 and counterclockwise rotation. Is rotated. And when the second end 14 of the leaf spring has crossed the connecting line between the first end 13 and the guess 3 to the front side, the elastic force of the leaf spring 12 rotates the handle 2 in the counterclockwise direction. It acts as a force to rotate.

The handle 2, which has been protruded and rotated to a position where it can be lifted out, is withdrawn again by the operator's hand, and the latch plate 6 whose hole edge of the operation hole 17 is pressed by the manipulator 15 of the handle 2 is pressed. ) Rotates in the clockwise direction in FIG. 2 and is separated from the housing on the casing body side.

As a result, the door lock on which the case 1 is mounted is unlocked from the casing body.

As described above, when the handle 2 is protruded or immersed, the leaf spring 12 is centered around the first spring receiving portion 8 on the case side and the second spring receiving portion 9 on the handle side. In the case of repeating the oscillation motion and the expansion motion, or in the push button type flat handle device of the present invention, the first end portion 13 and the second spring accommodation part of the leaf spring inserted into the first spring accommodation part 8. The sharpening protrusions 10 and 11 are respectively provided in the second end 14 of the leaf spring inserted into (9), and the sharpening protrusions 10 and 11 are the first spring receiving portions 8 or the number of second springs. The first end 13, the second end 14, the first spring receiving part 8, or the second spring receiving part 9 of the leaf spring 12 are coupled to each other in a state where they are attached to the soldering part 9. There is no escape from

In other words, according to the present invention, there is no useless dropout of the leaf spring 12 and a pushbutton type flat handle device which always operates stably is easily obtained.
