Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a push-acting type flat handle device used for doors of distribution boards, control boards and the like.

[Prior Art] In the conventional push-acting type flat handle device with a push button, when the push button is pushed when the door is unlocked and the base end of the handle body is pushed by the tip projection of the push button, the handle body is gripped. Project to the possible angular position. Further, when the door is locked, the door can be locked simply by closing the door and pushing the handle body into the retracted position in the case against the bias of the spring.

[Problems to be Solved by the Invention] However, this conventional device has a simple locking method, and may be in a locked state even when the door is opened due to force or impact applied to the handle body. .

If the door is accidentally closed in this state, the stopper plate will come into contact with the front frame part of the cabinet body, etc., and the front frame part may be damaged or the stopper plate and the guide screw are excessively large. Such stress may be applied to the part, resulting in damage to the part.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a push-acting type flat handle device capable of accurately preventing a door from being accidentally locked and closed.

[Means for Solving the Problems] The following will describe with reference numerals in the accompanying drawings. The gist of the present invention is that the handle main body 5 is the case 2 when the door is locked.
When the handle body 5 is pressed through the push button 8 or directly, the handle body 5 rotates around the pivot shaft 4 at the base end and protrudes from the case. In the pressing actuating type planar handle device in which the stopper plate 11 is rotated to the unlocked position by the operating protrusion 3 of FIG.
A base end of the case is pivotally attached by an orthogonal pivot 21, and a through hole 23 through which the curved support bar 20 is rotatably inserted in the bottom wall of the case 2.
And a stepped surface 24 is provided at the tip of the curved support rod 20,
The stepped surface 2 of the curved support rod 20 when the handle body 5 is projected.
4 is engaged with the edge of the through hole 23.

[Operation] When the push button 8 is pushed to unlock the door and the base end step surface 7 of the handle body 5 is pushed, the handle body 5 projects to an angle position where it can be gripped. When the handle body 5 is further pulled out from the case 2 and rotated, the stopper plate 1 pivotally attached to the back surface of the case 2 by the screw 9 and guided by the screw 17.
1 is rotationally driven to the unlocked position by the actuating protrusion 3 of the handle body 5 that pushes the edge surface of the passive hole 10, and is separated from the receiving portion 14 of the cabinet body 25.

The curved support rod 20 pulled by the handle body 5 as the handle body 5 rotates is rotated about its orthogonal pivot 21 by its own weight, and the inside of the through hole 23 of the case bottom wall faces the front side of the case 2. Slide.

At the end of rotation of the handle main body 5, the step surface 24 at the tip of the curved support rod 20 engages with the hole edge below the through hole 23, so that the handle main body 5 is prevented from being pushed into the case 2. To be done.

At the time of locking after closing the door 1, the curved support bar 20 is once pushed up, and the tip end of the curved support bar 20 is slightly moved upward in the through hole 23, so that the lower hole edge of the through hole 23 is closed. The engagement between the portion and the step surface 24 is released. After performing such an additional operation, the handle body 5 is pushed into the case 2.

[Embodiment] As shown in FIG. 4, the present invention does not include a push button member separately from the handle main body, but the push-in operation portion 22 is integrally formed on the entire base end portion of the handle main body 25. Can also be applied to.

[Advantage of the Invention] As described above, in the present invention, the base end of the curved support bar 20 is pivotally attached to the tip of the handle body 5 by the orthogonal pivot 21.
A through hole 23 through which the curved support rod 20 is rotatably inserted is provided in the bottom wall of the case 2, and a step surface 24 is provided at the tip of the curved support rod 20.
Since the step surface 24 is engaged with the hole edge portion of the through hole 23, the handle body 5 is securely held at the protruding position in the unlocked state. Therefore, it is possible to accurately prevent a damage accident of the handle device or the cabinet body due to closing the door 1 in a locked state where the stopper plate 11 projects to the side of the door 1.

Further, in the present invention, the support member of the handle body 5 is composed of the curved support rod 20, and in the locked state, the curved support rod 20 protrudes to the rear surface side of the case 2 so that the tip end thereof is close to the bottom wall of the case. As compared with the case where the support rod is composed of a straight rod, the amount of protrusion to the back side of the case is significantly reduced, and the internal space of the cabinet body can be effectively used.
