Press the inner compression rod 8 and rotate the actuating lever 11 to push the water pin 15 at the inner end of the actuating lever 11 and slide the lock shaft 14 to the outside to rotate the lock shaft ( The inner end portion of the 14 is released from the bearing hole 13 of the movable body 7, thereby enabling the movable body 7 to be rotatable with respect to the fixed seat 10.

In the illustrated embodiment, the handle device 2 of the home device is fixed to the front of the door 1 by a suitable fixing means such as a bolt, so that the fixed seat 10 of the collection device 4 of the home device is a bolt or the like. It is fixed to the front surface of the solid frame wall 3 by suitable fixing means.

The height adjusting end 55 is fixed to the movable body 7 of the collection apparatus 4 by the two buses 56, and the roller type collection member 6 is equipped in this front end part.

The locking member 5 of the handle device 2 insulated the handle 45 in parallel with the front surface of the door 1, and the door 1 was fixed to the fixed frame wall 3 by engaging with the collection member 6. Stop incapable of opening.

With respect to the guide hole 9 for the push rod 8, a pair of upper and lower bearing bosses 17 and 18 protrude from the fixed fore end portion of the opposite shaft of the door 1, that is, the outer end of the fixed seat 10.

The upper and lower side walls 19 and 20 of the movable body 7 are provided with 21 and 22 at the outer end portions thereof. These perforations 21 and 22 and the perforations 23 and 24 of the bearing bosses 17 and 18 are provided. The movable main body 7 is rotatably attached to the stationary seat 10 by the pivot rod 25 inserted in it.

In the stationary seat 10, the cylindrical part 52 and 53 are protruded in the front side and the back side surrounding the said guide hole 9. As shown in FIG.

The U-shaped support plate 26 in cross section engages the semi-circular upper section 47 on the inner end side thereof with the single cylindrical portion 52 so as to abut against the front of the fixed seat 10 and from the through hole 50 of the fixed seat 10. It is fixed to the fixed seat 10 by one screw which screwes into the screw cylinder part 48 of a support plate center part.

The single cylindrical portion 53 on the rear side is fitted into the inner and outer through holes 44 of the solid frame wall 3 in fixing the fixed seat 10 to the frame wall 3.

Perforations 29 and 30 are provided at the outer ends of the pair of standing side walls 27 and 28 of the support plate 26, and perforations 31 and 32 are provided at the outer end protrusions of the operating lever 11.

The actuating lever 11 is rotatably attached to the support plate 26, and eventually to the outer end of the fixed seat 10, by the pivot pin 54 inserted into the through holes 29, 30, 31 and 32.

As shown in FIGS. 10 and 13, one end of the coil spring 49 fitted to the axis pin 54 abuts on the support plate 6, while the other end of the spring 49 is connected to the actuating lever 11. Since the abutment lever 11 is rotated in the front direction of the fixed seat 10, the actuating lever 11 abuts against the single cylindrical portion 52.

The rotational bias by the coil spring 49 makes the return operation of the operating lever 11 when the pressing of the high internal compression rod 8 stops.

Two locking shafts 14 are used to increase the connection strength between the fixed seat 10 and the movable body 7. The middle of each lock shaft 14 is provided with a screw hole 51 in the radial direction, and the manual pin 15 is screwed in there.

Guide holes 38 and 39 are formed in the upper and lower ends of the standing walls 37 formed between the bearing bosses 17 and 18 of the stator 10 so that the small diameter outer end of the lock shaft 14 is rotatably and slidably fitted. I install it.

Since the manual pin 15 in the middle of the lock shaft is in contact with the inclined cam surface 16 of the fixed seat inner end portion 10a at the proximal end of the lock shaft, the inclined cam surface 16 is formed in a spiral with a central angle of 90 °. The lock shaft 14 is shown in FIG. 12 when the manual pin 15 slides along the inclined cam surface 16 and reaches the stable position shown in FIGS. 11 and 13 by the sliding bias of 41. It turns 90 degrees from one retreat position.

The tip end portion of the operating lever 11 is formed in an inverted U shape in cross section so that the blade pieces 33 and 34 protrude from the upper and lower angular axes. Pressing the actuating lever 11 in the high inner pressure rod 8 inserted through the inner and outer through holes 44 of the solid frame wall 3 and the guide hole 9 in the center of the fixed seat, the actuating lever 11 is the pivot pin 54. Rotate around the center and press the manual pin (15) on the blade (33, 34).

In this way, the lock shaft 14 rotates 90 degrees in the reverse direction while supporting the spring 41 and slides outward along the bearing hole 12.

In the final stage of rotation of the operating lever 11, the inner end of the lock shaft 14 escapes from the bearing hole 13 on the movable body side, whereby the restraint of the movable body 7 on the fixed seat 10 is released.

When the push rod 8 is pressed again, as shown in FIGS. 3 and 9, the movable main body 7 rotates on the outer shaft about the pivot rod 25 and the collection member 6 is handled. ) Is separated from the locking member (5).

In this way, the stop of the door 1 with respect to the solid frame 3 pulls the handle 45 of the handle device 2 from the high outside and accurately releases it from the high internal shaft without retracting the locking member 5. Will be.
