Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a handle device that is used for the door of a commercial refrigerator, etc., and that allows the door to be fully locked with a lock on a fixed frame such as a box body as necessary. It is something.

(Prior art) An operating handle is pivotally attached to a main body case that is fixed to a door, and a latch that engages and disengages from a receiving part on the fixed frame side is slid and biased by a spring and housed in the main body case. An actuation plate that engages with the passive part is fixed to the tip of the operating handle, a lock is embedded in the middle of the operating handle, and a stop plate that protrudes into the main body case is fixed to the rotor of the lock to fix the door. When it is desired to lock the frame, the stop plate is rotated with a key inserted into the rotor, and the stop plate is directly or indirectly engaged with the base end of the latch. A handle device for a door with a lock which prevents the latch from sliding backward due to pulling and rotation of the handle is already known as disclosed in Japanese Utility Model Application Publication No. 80259/1983.

(Problem that the invention attempts to solve) However, with this conventional handle device,
The lock is permanently fixed to the operating handle, and the lock remains attached to the operating handle at all times.

Therefore, when this handle device is applied to a commercial refrigerator installed in a kitchen, the door needs to be opened and closed frequently depending on the cooking process, and it is not necessary to lock the door every time it is opened and closed. However, locks are constantly exposed to various cooking ingredients and liquids and are subject to contamination.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a door handle device that allows the lock to be removed and placed elsewhere in situations where the door does not need to be locked, and that prevents the lock from becoming dirty or corroded. .

(Means for Solving the Problems) As explained below using reference numerals in the attached drawings, the lock-removable door handle device of the present invention includes a fixed handle 2 fixed to a door 1, and a fixed handle 2 fixed to a door 1. A latch 6 is slidably accommodated in a latch accommodating portion 3 at the base end of the latch 6, and a distal end portion 6a engages and disengages from a receiving portion 5 on the fixed frame 4 side. an operating lever 9 which is pivotally connected to the fixed handle 2 by a pivot 8 and which pushes the passive part 11 of the latch 6 with an operating protrusion 10 when it is drawn toward the fixed handle 2; A lock accommodating part 13 is provided on the fixed handle 2 facing the tip part away from the pivot 8 of the operating lever 9, and the lock accommodating part 13 is removably fitted into the lock accommodating part 13, and the tip part 14a is attached to the back side of the fixed handle 2. A lock 14 that protrudes from the top and comes into contact with the operating lever tip 9a, and an extractor that is connected to a rotor 15 of the lock 14 and that engages and disengages from a receiving portion 17 on the fixed handle 2 side by rotation of a key 16 inserted into the rotor 15. It consists of a stopper body 18.

(Embodiment) In the illustrated embodiment, the fixed handle 2 is fixed to the door 1 by screws 21 and nuts 22 inserted into through holes 20 of the mounting flanges 19 on both sides of the base end. A receiving recess 12 of the operating lever 9 is formed in the shape of a groove on the back side of the fixed handle 2 along its length, and the receiving recess 12 communicates with the latch receiving part 3.

The operating protrusion 10 of the operating lever 9 is inclined at an angle of about 80 degrees with respect to the main body of the operating lever 9, and its tip end is inserted into the elongated hole-shaped passive portion 11 of the latch 6. As the lock 14, various types of lock mechanisms can be used, but in this embodiment, a disk tumbler lock mechanism is used. The rectangular rod-shaped retaining body 18 moves in and out of the outer circumferential surface of the lock main body in the diametrical direction as the rotor 15 rotates forward and backward.

(Function) For example, when this handle device is attached to the door of a commercial refrigerator, the door needs to be opened and closed frequently, and during business hours when there is no need to lock it each time, the key inserted into the rotor 15 is used. At step 16, the rotor 15 is rotated in a predetermined direction so that the retaining body 18 is recessed into the lock main body, and the engagement between the retaining body 18 and the receiving portion 17 is released.

The lock 14 unlocked to the fixed handle 2 is removed from the lock accommodating portion 13 of the fixed handle 2 and placed in an appropriate storage location. When the lock 14 is removed, the operating protrusion 10 of the operating lever 9 can be rotated toward the back of the fixed handle 2 and retracted into the receiving recess 2.

Therefore, when the main body parts of the operating lever 9 and the fixed handle 2 are gripped together and the main part of the operating lever 9 is buried in the receiving recess 12 of the fixed handle 2, the driven part 11 is pushed by the actuating protrusion 10. The latch 6 slides sufficiently backward against the bias of the spring 7,
The fixed frame body 4 is detached from the receiving part 5.

The door 1, which is thus unlocked from the fixed frame 4, is opened by pulling the fixed handle 2. When the door 1 is rotated in the closing direction, the receiving part 5
The tip slope portion 6b of the latch 6 is attached to the tip cam surface portion 5a of the latch 6.
Due to this contact, the latch 6 automatically slides backward by a predetermined stroke, and at the next instant, the latch 6 moves forward and the latch 6 and the receiving part 5 engage sufficiently deeply. The door 1, which is frequently opened and closed during business hours, is stably locked in the closed position by the temporary locking action of the spring-biased latch 6 and the receiving part 5.

When business hours are over and you no longer need to open the refrigerator, use the lock 1 you brought from the storage area.
4 is refitted into the lock accommodating part 13 of the fixed handle 2, and the rotor 15 is turned in the opposite direction with the key 16 to re-engage the retaining body 18 and the receiving part 17. In this state, the tip 14a of the lock 14 protrudes from the receiving recess 12 of the operating lever 9, and rotation of the main body of the operating lever 9 is prevented by the lock tip 14a, so the operating lever 9 is fixed to the handle. It cannot be attracted to the subject part of 2. Therefore, the latch 6 is stopped at the door locking position where the latch 6 is deeply engaged with the receiving part 5.

(Effects of the Invention) As described above, the lock removable handle device of the present invention has a tip portion 9a remote from the pivot shaft 8 of the operation lever 9.
A lock accommodating portion 13 is provided on the fixed handle 2 facing the lock accommodating portion 13, a retainer 18 is fixed to the rotor 15 of the lock 14 which is removably fitted into the lock accommodating portion 13, and the retainer 18 is provided on the fixed handle 2 side. The door 1 is provided with a receiving part 17 for engaging and disengaging the body 18, and in situations where the door 1 does not need to be firmly locked with respect to the fixed frame 4,
By rotating the key 16 inserted into the rotor 15, the lock 14 can be removed from the fixed handle 2 by detaching the retaining body 18 from the receiving part 17 and placing it there, so it is possible to accurately prevent the lock 14 from being soiled or corroded. .

Furthermore, in the handle device of the present invention, the rotation of the operating lever 9 is directly blocked by the lock 14 itself, and no other interlocking mechanism or additional blocking member is required, so the structure is simplified. , manufacturing and processing costs can be reduced.

Furthermore, in the present invention, the tip 14a of the lock 14 attached to the fixed handle 2 protrudes toward the back side of the fixed handle 2, and it is clearly seen that this prevents the operation lever 9 from moving. Erroneous operation of trying to pull the operating lever 9 toward the fixed handle 2 in the attached state is prevented.

In addition, since the lock accommodating portion 13 is provided on the fixed handle 2 so as to face the tip 9a of the operating lever 9 which is far away from the pivot 8, in the unlikely event that the operating lever 9 is placed on the fixed handle 2 side when the lock is attached. Even if the lock is forcibly pressed, the force applied to the lock 14 is relatively small, and the lock 14 will not be distorted or damaged.
