Description

Door lock handle device with correction mechanism

[Technical field to which the design belongs]

The present invention relates to a lock handle device mounted on a door of a commercial refrigerator or a refrigerator, and used to lock the door to a fixing frame such as a refrigerator body.

[Prior art]

As disclosed in Japanese Patent Application Laid-Open No. 60-70157, the main body of the apparatus is firmly attached to the door, and the support is firmly attached to the fixing frame body, so that the latch body engaged with the support member can slide on the apparatus body. A handle for receiving and sliding the latch body directly or indirectly by sliding back and forth is pivotally mounted to the device body with an axial pin, and a lock plate for restraining the latch body in the locked position is firmly attached to the device body so that the lock unit is attached to the device body. The door lock handle device for which the lock cam which releases the engagement of the lock plate and the latching | locking part of a latch body is firmly attached to the rotor of the lock unit is known conventionally.

In this conventional apparatus, when the door is rotated close to the hinge shaft of one end, the arc body cam face of the front end of the latch body is brought into contact with the roller of the supporter at the end of the rotation, so that the latch body automatically slides back against the built-in spring. When the door is completely closed and the front end of the latch body comes to the back side of the roller of the bushing, the latch body is protruded and slipped by the action of the built-in spring, and the door is engaged with the roller of the bushing to a predetermined depth so that the door is fixed to the fixed frame body. Lock out of position.

When the refrigerator is not opened or closed for a while due to work, a predetermined key is inserted into the lock unit to prevent the door from being opened by an unauthorized person, and the lock plate is hung on the latch body by rotating the lock cam connected to the lock unit's rotor in the clockwise direction. Customize As a result, even when the handle is pulled and rotated, the latch body does not move backward and slip, and full-fledged correction is achieved.

In refrigerators and the like, the door is closed while compressing the sealing member such as a gasket. When the rotational force applied to the door is insufficient during the closing operation, the sealing member is not sufficiently compressed. Therefore, the latch body does not completely protrude from the apparatus body to a predetermined distance. There is no time.

In the conventional apparatus, in such a state that the locking of the door by the latch body and the receiving device is incomplete (semi-fastening state), there is no mechanism for preventing rotation of the lock cam, so that the operator can rotate the rotor of the lock unit to the locked position.

In the semi-tight state, however, the latching portion of the latch body is in a retracted position from the normal position, and the lock plate is in a state where it is mounted on the front surface of the latching portion, even if the lock cam is rotated in the clockwise direction. The alignment of the sieve does not hold. For this reason, when the handle is pulled out and rotated, the latch body slides backward, and the engagement between the latch body and the receiving member is released at that position.

That is, in the half-tight state, even if the lock of the lock unit is not secured no matter how much the rotor of the lock unit is rotated to the locked position, the operator misunderstands that the rotor has been rotated to the corrected position, thereby realizing corrected correction. I'm leaving the place. For this reason, the door that is left unattended without realizing the corrective action is opened, and there is a fear of theft of the stored product.

[Problem that plan is trying to solve]

Therefore, the object of the present invention is that the door lock handle with a visibility check mechanism that can check the semi-fastening state on the spot because it can not rotate the rotor of the lock unit in the semi-fastening state, and can give an opportunity to reclose the door. To provide a device.

[Means for solving the problem]

In the present invention, the apparatus body 1 is firmly attached to the door 20, and the support 22 is firmly attached to the fixing frame 21 in the present invention. The latch body 3 which hangs or peels off is slidably accommodated in the apparatus body 1, and the handle 2 which makes the latch body 3 slide back or indirectly by the shaft pin 8 is the apparatus body. The lock plate 15 which pivotally mounts to (1), restrains the latch body 3 to the locked position, is firmly attached to the apparatus body 1, and the lock unit 7 is mounted to the apparatus body 1, In the door lock handle device in which the lock cam 11, which releases the lock plate 15 and the latch body 3 from each other, is firmly attached to the rotor 28 of the lock unit 7, the outer surface of the lock cam 11 is provided. An arc-shaped recess in which a fan-shaped protrusion 5 is provided and the fan-shaped protrusion 5 can penetrate into the inner wall surface 23 of the latch body 3 facing the lock cam 11. When the portion 18 is provided so that the latch body 3 is in an incompletely protruding position, the fan-shaped protrusion 5 abuts against the inner wall surface 23 of the latch body 3.

As shown in FIG. 3, when the protrusion amount of the latch body 3 is insufficient, and the door 20 is in the semi-fastened state, the arc-shaped recess 18 of the latch body 3 is a fan of the lock cam 11. The fan-shaped projection 5 is not in a position directly facing the shaped projection 5 but is in contact with the inner wall surface 23 of the latch body 3. For this reason, even if an operator tries to turn the rotor 28 in the locking direction by inserting the key 6 in the lock unit 7, it will be blocked by the inner wall surface 23 of the latch body 3.

The operator who realized strangely that the rotor 28 cannot be rotated, pulls the handle 2 and rotates it to open the door 20 once and give the rotational force greater than the previous rotation to reclose the door 20.

When the latch body 3 completely protrudes by a predetermined distance by this reclosing and the latch body 3 is engaged with the support 22 at a predetermined depth, the latch body 3 is shown in FIG. Since the arc-shaped concave portion 18 of the lock cam 11 is directly facing the fan-shaped protrusion 5 of the lock cam 11, the operator inserts the key 6 into the lock unit 7 to correct the rotor 28. When turned in the direction, the fan-shaped protrusions 5 dig into the arc-shaped recesses 18, and the lock cam 11 rotates to a predetermined angle. In this manner, when the lock cam 11 is rotated to the locked position, as shown in FIG. 2, the latch plate 26 of the lock plate 15 is engaged with the latch shoulder 25 of the latch body 3. The retraction slipper of (3) is prevented, and the corrective action is achieved by removing the key 6 from the rotor 28.

The key 6 is inserted into the rotor 28 to be rotated in the reverse direction to release the corrective locking, and the latch plate 26 of the lock plate 15 is latched by the cam inclined surface 29 of the lock cam 11. 3) is separated from the locking shoulder 25. Depending on the size of the rotation angle in the unlocking direction of the lock cam 11, the recessed portion for entering the fan-shaped protrusions 5 into a separate inner wall surface 27 facing the inner wall surface 23 of the latch body 3; Install (19).
