Description

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

  Pop-out door lock handle devices are widely used in vending machines. The lock handle device has a fixed case fixed to the door and a handle incorporated in the fixed case. In the unlocked state, the handle protrudes forward from the fixed case and can be rotated. However, in the locked state, the handle is buried in the storage recess of the fixed case, and the door cannot be opened. In the unlocked state, the clasp plate is engaged with and disengaged from the housing by rotating the handle protruding forward from the fixed case between the locked position and the unlocked position (see Patent Document 1). In the shaft tube portion of the handle, a dead bolt that protrudes from the shaft tube portion to the outer peripheral side in the locked state and engages with the fixed case, and a lock unit that operates the dead bolt by rotation of the rotor are mounted. When the handle is pushed into the fixed case at the locked position, the dead bolt automatically protrudes and is locked. By rotating the rotor of the lock unit by key operation, when the dead bolt is brought to the unlock position, the lock is unlocked. At the same time, the handle pops forward by the urging force, and the door can be opened by the handle.

The lock handle device 1 includes a fixed case 2 fixed to the door D, and a handle 3 incorporated therein so as to be housed and projectable.

  The fixed case 2 has a bearing tube portion 4 and a handle storage portion 5. The handle 3 includes a shaft tube portion 6 that is inserted into the bearing tube portion 4 of the fixed case 2 and a grip portion 7 that extends from the front end of the shaft tube portion 6 in the direction orthogonal to the axis. On the front side of the handle housing part 5 of the fixed case 2, a recess 5 a for receiving the grip part 7 of the handle 3 is formed. As shown in FIG. 1, the handle 3 is accommodated in the recess 5 a so that the front surface thereof is flush with the front surface of the fixed case 2.

  An inner cylinder 8 is inserted into the bearing cylinder 4, and a shaft cylinder 6 of the handle is inserted inside thereof. The inner cylinder 8 can rotate within a range of approximately 90 ° between the locked position and the unlocked position, and cannot move in the front-rear direction.

  The shaft tube portion 6 of the handle is not rotatable relative to the inner tube 8. Therefore, the shaft tube portion 6 is integrally locked with the inner tube 8 in the bearing tube portion 4 and unlocked (FIG. 1). Rotate between positions (virtual lines in FIG. 3). Moreover, the shaft cylinder part 6 is a front-back direction between the unlocking position (imaginary line of FIG. 1) which protruded ahead from the bearing cylinder part 4, and the locking position (solid line of FIG. 1) pushed into the bearing cylinder part 4. And is biased by the spring 9 in the unlocked position, that is, in the protruding direction.

  As shown in FIG. 1, a marker seal 18 colored with a fluorescent paint or the like that can easily recognize the unlocked state is attached to the front surface of the handle housing recess 5 a of the fixed case 2. Instead of the marker seal 18, the front surface of the handle housing recess 5a itself can be colored to be a marker.

  As shown in FIGS. 1 and 4, the head surface 15a, the shoulder surface 16a and the leg end surface 17a, which are both end surfaces in the insertion direction of the retaining metal fitting 14, are unlocked, that is, the shaft tube portion 6 is a bearing tube. A colored portion (hereinafter referred to by the same reference numerals 15a, 16a, and 17a as each end face) is provided as an unlocking mark that can be easily visually recognized as protruding from the portion 4. The colored portion as the unlocking mark may be formed by directly applying a paint to the outer peripheral surface of the shaft tube portion 6, but it is applied to both end surfaces 15a, 16a, and 17a of the retaining metal fitting 14 in the processing step. Easy to do. Also by this method, the colored portions 15a, 16a, and 17a can be visually recognized from all angles. The unlocking mark by coloring the retaining metal fitting 14 can be selectively employed or used together with the unlocking mark 18 provided on the front surface of the handle housing recess 5a.

  The lock handle device 1 closes the door D, rotates the handle 5 to the lock position shown in FIG. 1 and pushes it into the fixed case 2, so that the grip 7 fits in the housing recess 7a and at the same time the dead bolt 12 It protrudes radially outward and engages with the bearing tube 4. Thereby, the door D is locked in the locked state. To open the door D, the lock unit 11 is unlocked by a key (not shown), the rotor 11a is rotated, and the dead bolt 12 is retracted, whereby the shaft tube portion 6 of the handle 3 is pushed forward by the spring 9. If the handle 3 is rotated 90 ° and brought to the unlocked position, the clasp plate 10 is detached from the housing, and the door can be opened. When the lock handle device 1 is in the unlocked state, the handle 3 protrudes from the fixed case 2, and in this state, the unlocking mark 18 of the handle housing recess 5a or the unlocking marks 15a, 16a of the retaining bracket 14 is provided. , 17a are exposed.
