According to the handle device for an opening / closing door according to the first aspect of the present invention, when the opening / closing door is opened, as a matter of course, the handle can be rotated to open the door. At this time, the interlocking rod moves up and down, but since the large diameter portion does not engage with the large diameter hole portion, the rotation lock portion of the handle does not act.

When the door is separated from the opening frame, the pressure receiving portion of the trigger protrudes from the base plate portion and comes out (state of FIG. 5), and the large-diameter hole portion provided in the vertically moving interlocking rod serves as the trigger. Up and down movement of the interlocking rod is prevented by engaging with the large diameter portion. This blocking locks the rotation of the handle.

When the open / close door is closed (FIG. 2 (b), FIG. 4 state) and the pressure receiving portion of the trigger is pressed against the opening frame, it is retracted into the base plate portion against the spring, and is set in a retracted state. As a result, when the large-diameter portion is disengaged from the large-diameter hole portion, the interlocking rod is free to move up and down, so that the handle is rotatable and the door can be opened.

FIG. 1 shows an embodiment of the present invention, in which a vertical shaft 1a at the front end of a door 1 which is an opening / closing door is pivotally supported by a handle shaft 4 having a rectangular cross section which is a rotating shaft of a handle 2. In the vicinity of the handle shaft 4, there is provided an interlocking device 5 that converts the rotational movement of the handle shaft 4 into a reciprocating motion, for example, a rack and a pinion mechanism (not shown).

A slide body 7 is arranged in a groove of an opening / closing machine frame 6 which is integrally provided with the interlocking device 5 and has a U-shaped cross section and which is vertically framed. ing. At the lower end of the slide body 7, a long interlocking rod 8 is arranged in a groove formed vertically along the side surface of the vertical frame 1a at the tip of the door 1, and is detachably connected by bolts and nuts 9 and 9. Has been done.

The interlocking rod 8 is formed in an inverted U-shaped cross section, and as shown in FIG. 1, is arranged so as to be reciprocally movable by a constant stroke in a groove 1b formed at the front end of the vertical frame 1a of the door. . In the vicinity of the lower end portion of the interlocking rod 8, a cutout portion 10 including a long hole portion 10a and a large diameter hole portion 10b is provided.

On the other hand, the notch 10 is provided with a trigger T. The trigger T has a substrate portion 11, and this substrate portion 11
From the base 12, the press receiving portion 13 is configured to be elastically held by the springs 12 and 12 so as to project and retract.
In addition, the engaging portion 14 has a large diameter portion 14a and a small diameter portion 14b which are interlocked with the pressing receiving portion 13 coming in and out from the substrate portion 11.

As shown in FIG. 3, the base plate portion 11 is formed of a rectangular parallelepiped frame body as a whole, and is fixed to the vertical frame 1a of the door by legs 11a and 11b penetrating the cutout portion 10. Although these legs 11a and 11b are inserted through the notches 10, they have a shape that does not affect the vertical movement of the interlocking rod 8.

The pressure receiving portion 13 is formed in the central portion of the substrate portion 11 in a direction perpendicular to the length direction of the substrate portion 11, in other words, the cutout portion 1.
It is slidably supported in a certain range in the direction perpendicular to 0, and is normally provided by springs 12 and 12 so as to be extruded.

A contact roller 13a is pivotally supported at the tip of the pressure receiving portion 13 on the opening frame 3 side. With this configuration, the opening frame 3
The pressure receiving portion 13 can be smoothly mounted on and off the side tip, so that the pushing and receiving operation of the pressure receiving portion 13 can be smoothly performed.
