Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a push button type flat handle device used on the doors of distribution boards, control boards, etc.

(Prior art) In conventional push-button type flat handle devices, when the push button is pressed to unlock the door and the protrusion at the tip of the push button is pressed against the stepped surface of the base end of the handle body, the handle body adjusts to an angle that allows it to be gripped. protrude into position. Furthermore, when the door was to be locked, the door could be easily locked by simply closing the door and pushing the handle body into the retracted position within the case against the bias of the spring.

(Problems to be solved by the invention) However, with this conventional push button type flat handle device, the locking method is too easy.
If force or impact is applied to the handle body, the door may become locked even when opened.

Also, if you accidentally close the door in this state, the stop plate will come into contact with the door frame, which may damage the door frame or apply excessive stress to the stop plate and guide screw. The lock may become damaged.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a push-button flat handle device that can prevent the door from being accidentally closed while being locked.

(Means for Solving the Problems) The gist of the present invention will be explained below using reference numerals in the attached drawings. The main point of the present invention is that when the door is closed and locked, the handle body 5 is recessed into the case 2, and when the door is pressed, the handle body 5 is recessed into the case 2. 5 is a push-operated flat handle that rotates around a pivot 4 at the base end and projects from the case, and rotates a stopper plate 11 to an unlocked position by an operating protrusion 3 at the base end of the handle body 5. In the device, a support rod 20 is equipped at the tip of the handle body 5 so as to be floating and rotatable, and a step surface 20 is provided at the tip of the support rod 20.
A narrow portion 20a is provided through b, a long hole 24 is provided in the bottom wall of the case 2 through which the support rod 20 is passed, and the narrow hole 20a is inserted into the long hole 24. A portion 24a is provided, and the step surface 20b of the support rod 20 is brought into contact with the hole edge surface 24b of the narrow hole portion 24a when the handle body 5 is protruded.

(Operation) When unlocking the door, press the pushbutton 8 and release the handle body 5.
When the proximal end section 7 of the handle body 5 is pressed, the handle body 5 protrudes to an angular position where it can be grasped. Handle body 5
When it is further pulled out from case 2 and rotated, it is pivotally attached to the back of case 2 by screw 9, and screw 17
The locking plate 11 guided by the lock plate 11 is rotated to the unlocked position by the actuating protrusion 3 of the handle body 5 that presses the edge of the passive hole 10, and is pushed into the receiving position on the fixed frame side of the box body. It separates from the metal part 14. As the handle body 5 rotates, the support rod 20 mounted on the tip of the handle body 5 so as to be floating and rotatable rotates under its own weight and appears on the front side of the case 2. At the end of this rotation, the narrow part 20a at the tip of the support rod 20 is connected to the narrow hole part 24a of the elongated hole 24 in the bottom wall of the case.
into the narrow hole portion 24, and the step surface 20b is in the narrow hole portion 24.
It comes into contact with the hole edge surface 24b of a. Therefore, the handle body 5 is prevented from being pushed into the case 2.

When locking the door after closing it, first press the support rod 2.
0 slightly toward the front side of case 2, then press support rod 2
After performing an additional operation of rotating the support rod 20 to release the contact between the step surface 20b of the support rod 20 and the hole edge surface 24b of the narrow hole portion 24a, the handle body 5 is pushed into the case 2.

(Example) In the first embodiment shown in FIGS. 1 to 3, the support rod 20 is inserted into the slot 26 of the presser plate 22, and the support rod 20 is inserted into the support pin 21 whose both ends approach and separate from the presser plate 22.
The tip of the handle body 5 is machined as shown in FIG. The support rod 20 can also be directly attached to the handle body 5 in a floating manner by providing the support rod 20 in the portion 5a.

Further, in this embodiment, the narrow portion 20a is provided protruding from the center of the tip of the support rod 20, but the narrow portion may be provided protruding from only one side of the tip of the support rod 20. At this time, the shape of the elongated hole 24 in the bottom wall of the case is also changed accordingly.

Furthermore, as shown in FIGS. 4 and 5, the present invention can be applied to a flat handle device in which the push-in operation section 27 is integrally formed on the front surface of the base end of the handle body 25, and the handle body 25 is Pushing is prevented by a support rod 20 that is floatingly attached to the tip of the support rod.

(Effect of the invention) As described above, in the invention, the support rod 20 is pivotally attached to the tip of the handle body 5 in a floating manner, and the support rod 20
A narrow part 20a is provided at the tip of the case 2 via a step surface 20b, and a long hole 24 is provided in the bottom wall of the case 2 through which the support rod 20 passes. The narrow hole portion 24a to be inserted is provided, and the step surface 20b of the support rod 20 is brought into contact with the hole edge surface 24b of the narrow hole portion 24a when the handle body 5 is protruded, so that the handle body 5 is in the protruding state. This will ensure that the door is held securely and prevents damage to the handle device and door frame caused by closing the door 1 in a locked state with the stopper plate 11 protruding to the side of the door, which has been a problem in the past. It can be prevented.
