Description

The present invention relates to a pop-out type lock handle device used in a vending machine or the like.

[Prior Art] A pop-out type lock handle device disclosed in Japanese Patent Application Laid-Open No. 50-102149 has an outer cylinder protruding from a rear side of a main body case and is rotated on a rear end wall of the outer cylinder. The lock shaft is inserted through the lock shaft so as to be immovable in the axial direction, a male screw portion is provided on the rear peripheral surface of the lock shaft, and an inner cylinder body to be inserted into the outer cylinder body is projectingly provided on the handle, and the inner cylinder body is attached. The lock is housed and fixed in the front part of the inner cylinder by a spring urged forward, and the front part of the locking shaft is inserted into the rear part of the inner cylinder and connected by the interlocking member to interlock with the rotor of the lock. The latch that comes in and out from the through hole of the side wall of the inner cylinder is housed in the middle of the inner cylinder, and the male screw part of the locking shaft is screwed into the nut body supported by the fixed frame body to open the door. It is locked in the closed position and the tip of the latch is engaged with the receiving hole in the side wall of the outer cylinder to hold the handle in the retracted position. is there.

[Problems to be Solved by the Invention] The main body case is fixed on one side to a free end portion of a door pivotally attached to a fixed frame by a hinge, but in the conventional device, the outer cylinder itself is long. Since the male screw part of the locking shaft projects long from the rear end wall part of the outer cylinder, the width of the housing is narrow and the turning radius of the free end of the door is short.
It is impossible to use the pop-out type lock handle device because the rear end of the locking shaft collides with the edge of the housing or the like.

Therefore, the object of the present invention is to reduce the protrusion length from the back surface of the main body of the door, so that there is no hindrance to a vending machine or the like where the lateral width of the housing is narrow and the turning radius of the free end of the door is short. It is an object of the present invention to provide a pop-out type lock handle device that can be applied without any problems.

[Means for Solving the Problems] The pop-out lock handle device of the present invention will be described below with reference to the reference numerals in the accompanying drawings. The outer cylinder 3 is provided with the locking cylinder 4 which is provided with the body 3 projectingly and prevented from moving in the axial direction.
Rotatably accommodated therein, a locking nut body 5 is provided at the rear end of the locking cylinder body 4, and a plurality of split screw pieces 7 are moved in the central taper hole 6 of the fixing nut body 5 in the radial direction and the axial direction. It is accommodated as much as possible, and the divided screw piece 7 is slidably biased rearward by a spring 8 to abut against the inner surface of the central tapered hole 6.

Further, a lock bolt 10 that enters the locking tubular body 4 through the rear end small-diameter opening 9 of the central tapered hole 6 and is screwed into the divided screw piece 7.
Is provided on the fixed frame body 11, and the inner cylinder body 1 is inserted into the locking cylinder body 4 on the back side of the handle 12 housed in the main body case 2.
3, the inner cylindrical body 13 is slidably biased forward by the spring 14, the lock 15 is housed and fixed at the front end of the inner cylindrical body 13, and the lock 15 is locked at the rear end of the inner cylindrical body 13. A latch body 17 interlocked with the rotor 16 is accommodated.

Side through hole 18 of inner cylinder 13 and side elongated hole 19 of locking cylinder 4
Side receiving hole 20 through which the tip of the latch body 17 is engaged and disengaged
Is provided in the outer cylindrical body 3, and the latch body 17 separated from the side surface receiving hole 20 moves forward along the side surface elongated hole 19 so that the handle 12 projects from the main body case 2.

[Operation] When the predetermined key 40 is inserted into the lock 15 and the rotor 16 is rotated in the predetermined direction, the latch body 1 interlocked with the rotor 16
7 slides in the radial direction, the distal end of the latch body 17 escapes from the side surface receiving hole 20 of the outer cylinder body 3, and the side surface elongated hole 1 of the locking cylinder body 4
Since the inner cylinder body 13 is retracted inside, the inner cylinder body 13 is unlocked from the outer cylinder body 3, and the inner cylinder body 13 is slid forward along the outer cylinder body 3 and the locking cylinder body 4 by the urging force of the spring 14. And handle 1
2 protrudes from the inside of the main body case 2 to a grippable position.

In this way, at the end position where the handle 12 pops out, the tip end of the latch body 17 engages with the side edge of the front end portion of the side surface long hole 19, so that when the handle 12 is turned, the locking cylinder 4 and the fixed nut base 5 are rotated. Rotates in the same direction as the handle 9. With the rotation of the fixed nut body 5, the divided screw piece 7 is screwed forward along the inner surface of the central tapered hole 6 against the bias of the spring 8. In this way, the divided screw pieces 7 move in the centrifugal direction, so that the screw threads of the divided screw pieces 7 and the screw threads of the lock bolt 10 gradually become shallow.

At the stage where the handle 12 has rotated by a predetermined amount, the threaded engagement between the divided screw pieces 7 and the lock bolt 10 is completely released,
The locking and locking of the door 1 with respect to the fixed frame body 11 is released.
Therefore, the door 1 is opened by pulling the handle 12 toward you, and in the process, the lock bolt 10 escapes from the hollow portion between the split screw pieces 7, 7.

In the opened state of the door, the plurality of split screw pieces 7 are automatically moved backward by the biasing force of the spring 8 until they come into contact with the inner peripheral flange portion 63 of the fixed nut base 5, and along the inner surface of the central taper hole 6 in the centripetal direction. The moved divided screw pieces 7, 7 are in contact with each other at their side surfaces on the same circumference. When the door 1 is closed, the lock bolt 10 enters the hollow portion surrounded by the split screw pieces 7, 7 from the central hole 54 of the rear wall portion 53 of the outer tubular body 3 and pushes each split screw piece 7 forward. It is moved in the centrifugal direction along the inner surface of the central tapered hole 6.

When the split screw piece 7 moves by a predetermined amount and reaches a position where the screw thread of the lock bolt 10 can pass through the screw thread of the split screw piece 7, the forward movement of the split screw piece 7 is stopped, and thereafter, the split screw piece 7 is stopped. The screw thread of No. 7 just clicks on the screw thread of the lock bolt 10. At the final stage of closing the door 1, the split screw piece 7 is pushed by the spring 8 and moves slightly rearward, and at this time, the screw thread of the split screw piece 7 moved in the centripetal direction along the inner surface of the central tapered hole 6 is locked. Deeply engages the threads of the bolt 10.

After that, by turning the handle 12 in the opposite direction, the screwing of the assembly of the divided screw pieces 7, 7 and the lock bolt 10 progresses, and the door 1 is fully closed with respect to the fixed frame body 11. To be done. After the lock is established, the handle 12 is pushed into the main body case 2, and the distal end portion of the latch body 17 that has moved in the side surface long hole 19 of the locking cylinder body 4 engages with the side surface receiving hole 20 of the outer cylinder body 3. As a result, the inner cylinder 13 is locked again to the outer cylinder 3, and the handle 12 is held in the main body case 2 at a position where it cannot be gripped.
