DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a pop-out type door lock handle device used for a door of a vending machine or the like.

[0002]

2. Description of the Related Art As disclosed in Japanese Utility Model Laid-Open No. 6-22476, in a conventional lock handle device for a door used in a vending machine, a guide slot in a transverse direction between an inner cylinder and a handle shaft portion. The handle is locked at the position where the handle is housed in the case by engaging the tip of the dead bolt fitted into the case with the locking recess on the inner surface of the shaft cylinder portion of the case. To release the lock, the operation cam board is connected to the rotor of the lock unit embedded and fixed in the handle, and the drive projection provided eccentrically on the operation cam board is engaged with the passive groove at the base end of the dead bolt. This is performed by rotating the rotor with a key and pulling the dead bolt toward the inner cylinder by the drive projection.

However, since there is a play space between the driving projection of the operation cam board and the passive groove of the dead bolt, there is a certain delay between the rotation of the rotor by the key and the retraction of the dead bolt. Depending on the size of the play gap, the delay time of this operation is prolonged, and the operator who faces the situation in which the handle does not pop out despite turning the rotor with the key, turns the key more strongly or malfunctions. You will have to re-operate with a wrong feeling. Further, since only one dead bolt is prepared in the conventional device, locking of the handle may be insufficient, and the locking of the handle may be accidentally released due to tilting of the handle or resonance. There was also.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a secure and firm locking of a handle housed in a case, and there is no delay time between rotation of a rotor by a key and retraction of a dead bolt, and To provide a door lock handle device in which the pop-out operation of the door is smoothly and accurately performed, and the locking of the handle is not accidentally released due to resonance or the like.

[0005]

The lock handle device for a door according to the present invention will be described below with reference to the reference numerals in the accompanying drawings. The inner cylinder 2 is mounted so as to be rotatable and immovable back and forth, and a locking member 3 is connected to the rear end 2 b of the inner cylinder 2.
The handle shaft 4a of the handle 4 is inserted into the handle shaft 4a so as to be non-rotatable and slidable forward and backward, and is urged forward by a spring 5. The lock unit 6 is fitted and fixed to the handle shaft 4a, and the rotor 7 of the lock unit 6 The pinion 11 is fitted to the rear end so as to rotate integrally, and the guide grooves 9a and 9b in which the dead bolt 8 having the base end is the rack portion 8b are inserted in the diametrical direction across the inner cylinder and the handle shaft portion 4a. The dead bolt 8 is slid outward by a spring 10 supported on the inner surface of the handle shaft portion 4a, and the tooth row 11b of the pinion 11 is engaged with the rack portion 8b of the dead bolt 8, and the handle 4 The tip 8a of the deadbolt 8 is engaged with the locking recess 12 on the inner surface of the shaft cylinder 1a of the case 1 when the housing 1 is accommodated.

The dead bolts 8 can also be assembled in a pair up and down with the pinion 11 interposed. Correspondingly, guide slots 9a, 9b into which dead bolts 8 are
And a pair of upper and lower springs 10 supported on the inner surface of the handle shaft portion 4a slidably urge each dead bolt 8 to the outside, and a rotor of the lock unit 6 is provided. A pair of teeth 11b is provided on the peripheral surface of the pinion 11 interlocked with the upper and lower teeth 7, and each tooth 11b is engaged with the rack portion 8b of each dead bolt 8. Alternatively, the bottom surface 12a of the locking recess 12 may be formed in an arc shape, and the tip 8a of the dead bolt 8 may be brought into contact with the bottom surface 12a.

When the handle 4 is housed and locked in the case 1, the dead bolt 8 housed in the guide grooves 9 a and 9 b formed over the handle 4 and the inner cylinder 2 has a tip 8 a of the case 1. It is engaged with the locking recess 12. This engaged state is held by the sliding bias of the spring 10, and the handle 4 and the inner cylinder 2 are restrained from rotating relative to the case 1 and from moving forward.

To release the lock of the handle 4 with respect to the case 1, the rotor 7 is turned by a key to rotate the pinion 11 clockwise in FIG.
The dead bolt 8 is drawn into the handle shaft portion 4a by the cooperative action of the rack portion 8b of the dead bolt 8 and 1a. At the moment when the tip 8a of the dead bolt 8 comes off the locking recess 12 and the guide groove 9a of the inner cylinder 2, the handle 4 pops out forward by the biasing force of the spring 5.

When the handle 4 and the inner cylinder 2 are rotated with respect to the case 1 by grasping the protruding handle, the locking member 3 or the locking member connected to the locking member 3 is detached from the metal receiving portion on the fixed frame side. Then, the locking of the door to the fixed frame is released, and the door is opened by pulling the handle 4 toward the user.

[0010]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. The dead bolts 8 are provided in a pair at the top and bottom with the pinion 11 interposed therebetween. The locking recess 12 of the shaft cylinder 1a of the case 1 has a bottom surface 12a formed in an arc shape. The guide protrusion 13 of the handle shaft 2a is fitted in the guide groove 15 on the inner surface of the inner cylinder 2. Further, the guide pin 14 protruding from the handle shaft portion 4a is provided.
Is engaged with the vertical groove 2 a of the inner cylinder 2. By these,
The handle 4 cannot rotate with respect to the inner cylinder 2 and can slide in the front-rear direction.

[0011]

As described above, in the door lock handle device of the present invention, the pinion 1 is attached to the rotor 7 of the lock unit 6.
1 and the tooth row 11a of the pinion 11 is engaged with the rack 8b at the base end of the dead bolt 8, and the rotation of the pinion 11 in conjunction with the rotor 7 causes the dead bolt 8 to
And the drive shaft is driven forward and backward along the guide slots 9a and 9b of the handle shaft portion 2a, so that there is no delay between the rotation of the rotor 7 by the key and the retraction of the dead bolt 8, and the pop-out operation of the handle 2 is performed quickly and accurately. Done.

Since the rack portion 8b of the dead bolt 8 and the tooth row 11a of the pinion 11 are firmly meshed with each other, the dead bolt 8 does not unintentionally enter the handle shaft portion 4a due to vibration or the like. The lock of the handle 4 is not accidentally released.

In the door lock handle device according to the second aspect,
The pair of upper and lower teeth 11b, 11b of the pinion 11 is engaged with the rack portion 8b of each dead bolt 8, so that the handle 4 housed in the case 1 can be used. The case 1 can be securely and firmly locked to the case 1 without bias, and the unlocking operation can be smoothly performed without applying a bias force.

In the door lock handle device according to the third aspect, the bottom surface 12a of the locking recess 12 is formed in an arc shape, so that when the handle 2 is rotated to the locking position, the case 1 is locked.
The leading end portion 8b of the dead bolt 8 coming into sliding contact with the inner surface of the shaft cylindrical portion 1a is guided by the arc-shaped bottom surface 12a and smoothly engages with the locking concave portion 12.
