DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
In FIG. 1 to FIG. 7, reference numeral 1 denotes a main body of the lock handle device, the inside of which is cylindrical, and an operation handle 2 is integrally provided below one end of the front side of the main body 1. . Almost half of the main body 1 on the rear side in the length direction is fitted into the flange member 3 so as to be rotatable around the horizontal axis with respect to the flange member 3. The rear end portion of the main body portion 1 protrudes rearward from the flange member 3. The inside of the main body 1 is cylindrical as described above and penetrates in the length direction, and a storage space 5 for the cylinder 4 is formed in almost half of the front side in the length direction of the main body 1. A female screw hole 8 into which a bolt 7 for attaching the stopper 6 is screwed is formed in almost half of the rear side in the length direction of the portion 1. In the storage space 5, the cylinder 4 is stored so as to be rotatable around a horizontal axis, and one end 9 a of a first leaf spring 9 that is circularly curved so as to surround the outer periphery of the cylinder 4 is an outer periphery of the cylinder 4. The other end 9 b of the leaf spring 9 is engaged with an engagement groove 5 a formed on the inner peripheral surface of the storage space 5. In addition, in the fitting portion of the main body portion 1 with respect to the flange member 3, one end 10 a of the second leaf spring 10 that is circularly provided so as to surround the outer periphery of the main body portion 1 is formed on the outer peripheral surface of the main body portion 1. The other end 10 b of the leaf spring 10 is engaged with an engagement groove 3 a formed on the inner peripheral surface of the flange member 3. The body spring 1 is urged clockwise with respect to the flange member 3 by the leaf spring 10, and the cylinder 4 is urged clockwise with respect to the body portion 1 by the leaf spring 9. Incidentally, a storage space 12 for the dead pin 11 is formed adjacent to the rear end of the storage space 5. The storage space 12 for the dead pin 11 penetrates the main body 1 in the diameter direction, the dead pin 11 stored in the storage space 12 protrudes outside the storage space 12, and one end of the dead pin 11 is formed on the inner surface of the flange member 3. It is comprised so that it may latch on the groove part 14 which was. The dead pin 11 is engaged with a pin 16 which is provided at the rear end of the cylinder 4 and protrudes backward from a rotary piece 15 which rotates integrally with the cylinder 4, so that the cylinder 4 resists the urging force of the leaf spring 9. By rotating counterclockwise, the dead pin 11 that engages with the pin 16 moves in the radial direction of the flange member 3 and comes out of the groove portion 14 on the inner surface of the flange member 3, and the dead pin 11 and the flange member 3 are locked. In this state, the main body 1 is rotated clockwise with respect to the flange member 3 by the urging force of the leaf spring 10. By the way, the front end portion of the cylinder 4 built in the storage space 12 located above the handle 2 is covered with an openable / closable lid 18 that is pivotally connected by a screw 17, and the lid 18 is rotated to rotate the cylinder 4. The cylinder 4 can be rotated clockwise by inserting a key into the groove 4b formed in the front end of the cylinder 4 with the front end exposed.
[0009]
In the lock handle device having the above-described configuration, the cylindrical portion 3b that protrudes rearward of the flange member 3 is inserted into a hole (not shown) formed in the door 20 that closes the front opening of the housing 19 from the outside. It is attached to the door 20 by fitting and screwing the female screw member 21 into the outer surface male screw portion 3c of the cylindrical portion 3b protruding from the hole portion to the inside of the door 20 and tightening. A sheet packing 22 is interposed between the outer surface of the door 20 and the flange member 3, and a washer 23 is interposed between the inner surface of the door 20 and the female screw member 21. In this state where the lock handle device is attached to the door 20, the stopper 6 is externally fitted to the rear end portion of the main body portion 1 projecting rearward from the flange member 3, and the female screw hole 8 at the rear end portion of the main body portion 1. The bolts 7 are screwed onto and tightened to complete the mounting operation. By the way, when the stopper 6 is fitted on the rear end portion of the main body 1, the stopper 6 is sandwiched from the front and rear by a plurality of washers 24 so that the tightening force by the bolt 7 acts on the stopper 6.
[0010]
In the above configuration, when the closed door 20 is opened, the lid 18 is opened to expose the front end portion of the cylinder 4, and in this state, a key is inserted into the -groove 4b of the cylinder 4 to attach the cylinder 4 to the leaf spring 9. The dead pin 11 is pulled out of the groove 14 on the inner surface of the flange member 3 by rotating counterclockwise against the spring force of the flange member 3, and the locking of the cylinder 4 by the dead pin 11 is released. The main body 1 (including the handle 2) rotates in the clockwise direction with respect to the flange member 3 by the spring force of the leaf spring 10 while contacting the inner surface of the flange member 3. Due to the clockwise rotation of the main body 1, the clasp 6 attached to the rear end portion of the main body 1 by the bolt 7 is also rotated together and disengaged from the hole 19 b of the frame 19 a of the housing 19. And the door 20 can be opened. It should be noted that after inserting a key into the -groove 4b of the cylinder 4 and rotating the cylinder 4 counterclockwise against the spring force of the leaf spring 9, the cylinder 4 is removed when the force for rotating the cylinder 4 is removed. Is rotated to the original state by the spring force of the leaf spring 9, and the dead pin 11 tries to jump out of the hole 13, but the dead pin 11 is the inner surface of the flange member 3 unless the main body 1 is returned to the original state. It is impossible to engage with the groove portion 14.
[0011]
When closing the door 20 opened as described above, the door 20 is pushed directly by hand or the handle 2 is moved to close it, and the main body 1 is moved by holding the handle 2 when the door 20 is fully closed. By rotating the spring 10 counterclockwise by a predetermined angle against the spring force of the spring 10, the dead pin 11 is fitted into the groove 14 at the position of the groove 14 on the inner surface of the flange member 3, and the closed state is locked. In addition, by rotating the main body 1 counterclockwise by a predetermined angle against the spring force of the leaf spring 10, the clasp 6 is also rotated together and locked in the hole 19b of the frame 19a of the housing 19, The closed state of the door 20 can be maintained.
[0012]
【The invention's effect】
As described above, according to the present invention, when the door is opened, the lock of the closed state is released by inserting a key into the cylinder and rotating the cylinder, and the main body (including the handle) is also rotated by the leaf spring, By rotating the main body in the clockwise or counterclockwise direction, the clasp also rotates together and the lock with the housing is released. The door can be opened by grasping the handle, and the main body (including the handle) can be opened. There is no need to manually rotate the door, and the door opening operation can be easily performed. Also, when closing the door, the closed state is locked by grasping the handle and turning the main body part by a predetermined angle against the spring force of the leaf spring when the door is fully closed, and the key is inserted into the cylinder. Such an operation is unnecessary, and the door closing operation can be easily performed.
