Description

  The present invention relates to an opening / closing operation device that is attached to an opening / closing body such as an opening / closing door and is operated when opening / closing the door.

As this kind of opening / closing operation device, for example, a handle device disclosed in Patent Document 1 below is known. That is, the handle device includes a main body that is rotatably mounted on a receiving seat fixed to the opening and closing door, and a handle that is connected to the main body in a recess of the receiving seat so as to be retractable. The provided cam mechanism is unlocked to release the handle, and the handle is pulled out and gripped to rotate the main body.
Japanese Patent Application No. 6-159523

However, in the above-described handle device, since the cam mechanism and the handle are connected so as to be locked and unlocked, the structure becomes complicated and expensive, and the assembly work requires skill and the assembly time is increased. There were drawbacks.
An object of the present invention is to provide an opening / closing operation device that is simple in structure and easy to assemble.

The present invention has the following configuration in order to solve the above points.
<Configuration>
The present invention is an opening and closing operation device comprising a receiving seat attached to the opening and closing body, and a main body rotatably attached to the receiving seat,
A locking member having a rotation prevention groove provided on a surface of the receiving seat facing the main body, a locking member provided in the main body and protruding from the main body so as to be retractable and engaged with the rotation prevention groove; An elastic member for applying an elastic force to approach the opposing surface to project the projecting pin, a press button provided so as to be able to be pressed into the main body, and a press button formed integrally with the press button And a pin retreating member that moves the inclined portion engaged with the lock member to separate the lock member from the opposing surface against the elastic force.

  According to the present invention, when the push button is pushed into the main body, the inclined portion of the pin retreating member moves and separates the lock member from the opposing surface of the seat, so that the protruding pin of the lock member is disengaged from the rotation prevention groove by the retreat . Therefore, the main body can be directly rotated without providing a handle. That is, the present invention has a simple structure in which the main body is simply provided with a pin retraction member integrated with a lock member, an elastic member, and a push button, so that an assembling operation is facilitated and an inexpensive opening / closing operation device is provided. It is possible.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
4 and 5 are a front view and a side view of the opening / closing operation device according to the present invention. The opening / closing operation device includes a circular receiving seat 10 and a main body 11 rotatably mounted in a circular recess 10A of the receiving seat 10. The receiving seat 10 is attached to an opening / closing door (not shown). The main body 11 has an operating body 12 having arc portions 11A and 11B along the peripheral edges of the upper and lower circular recesses 10A in FIG. 4 and concave surfaces 11C and 11D on both sides, and a lid for closing the operating body 12. 13 (see FIG. 7).

  As shown in FIG. 6, a T-shaped recess 14 is formed in the operation body 12, and the lock member 20 shown in FIG. 3 is accommodated in the T-shaped recess 14. The lock member 20 includes an engaged portion 20a, a protruding pin 20b that rises from the engaged portion 20a, and pivot shafts 20c and 20c provided at the end of the engaged portion 20a. The lock member 20 is accommodated in the T-shaped recess 14 as shown in FIG. 3B, and is rotationally displaced about the pivot shafts 20c and 20c. A hole 20d into which one end of the coil spring 21 is engaged is provided on the bottom surface side of the engaged portion 20a, and the other end of the coil spring 21 is formed in a T-shaped recess 14 as shown in FIG. Is inserted into the hole 14a. Therefore, the engaged portion 20a of the lock member 20 is rotationally displaced by being applied with an elastic force by the coil spring 21, whereby the protruding pin 20b protrudes from the through hole 13a of the lid body 13 (FIG. 7).

  As shown in FIGS. 7A and 7B, the lid body 13 has a plate-shaped closing lid 13 </ b> A that is screwed to the operating body 12 to close the operating body 12. A shaft portion 22 is formed integrally with the closing lid 13A, and the shaft portion 22 is inserted through a boss 10B (see FIG. 5) at the center of the receiving seat 10. A latch (not shown) is fixed to the shaft portion 22 with a nut. The latch closes the open / close door in a state where it is engaged with a bracket or the like on the door frame side to which the door is attached.

  In FIG. 6 again, the operating body 12 is formed with a guide groove 15 communicating with the T-shaped recess 14. In the guide groove 15, the tip end side of the pin retracting member 25 shown in FIG. The pin retreating member 25 has a long hole 26 into which the protruding pin 20b of the lock member 20 is inserted, and an inclined surface portion 27 with which the engaged portion 20a of the lock member 20 is engaged.

  Further, the pin retracting member 25 is provided with projections 25a and 25a at the rear end, and the pressing button 30 is integrally formed. The protrusions 25a and 25a are brought into contact with the stoppers 12a and 12a of the operation body 12 to prevent the protrusion from the operation body 12. The push button 30 protrudes from an opening 12b provided in the concave surface portion 11C of the operation body 12 so as to be pushed.

  On the other hand, as shown in FIGS. 1 and 4, the receiving seat 10 is aligned with the through-hole 13 a of the lid body 13 on the plate surface 10 a facing the main body 11 (cover body 13) of the recess 10 </ b> A to prevent rotation. A groove 10C is formed. And the protrusion pin 20b which protrudes from the through-hole 13a of the cover body 13 is engaging with the rotation prevention groove | channel 10C, as shown to FIG. 1 (A). Accordingly, since the protruding pin 20b protruding from the main body 11 is engaged with the rotation preventing groove 10C on the receiving seat 10 side, the main body 11 cannot be rotated, that is, locked.

Next, the usage mode of the opening / closing operation device of the present invention will be described together with the operation.
While holding the operating body 12 (main body 11) with a finger, the push button 30 is pushed into the operating body 12 with the thumb.
When the push button 30 is pushed in this way, the pin retracting member 25 moves along the guide groove 15 in the arrow direction as shown in FIG. Since the inclined surface portion 27 is also moved by this movement, the engaged portion 20 a engaged with the inclined surface portion 27 is pressed against the elastic force of the coil spring 21 by the inclined surface portion 27, and the plate surface 10 a of the receiving seat 10. Is pushed down in a direction away from. Therefore, the protruding pin 20b moves backward and comes out of the rotation prevention groove 10C. Thereby, since the main body 11 can be rotated, the shaft part 22 can be rotated and unlocked, and the door can be opened.

  When the door is closed after being opened, the finger is released from the push button 30 to rotate the operation body 12 in the reverse direction. Thus, when the through hole 13a of the lid 13 is aligned with the rotation prevention groove 10C, the inclined surface portion 27 is pressed by the engaged portion 20a by the elastic force of the coil spring 21, so that the pin retracting member 25 moves in the reverse direction, As a result, the engaged portion 20a approaches the plate surface 10a, so that the protruding pin 20b engages with the rotation prevention groove 10C, and the rotation of the main body 11 is prevented.

  According to this embodiment, the lock member 20 is housed in the T-shaped recess 14 of the operating body 12 together with the coil spring 21, and the main body 11 is assembled simply by incorporating the pin retraction member 25 and screwing the closing lid 13A. The assembly work is easy.
