Description

  The present invention relates to a lock device provided in each door of an individual storage section such as a locker or cabinet in which a personal property such as a personal computer or a mobile phone is stored in an individual storage section and the door is closed and locked. More specifically, the present invention relates to a lock device in which a key attached to the lock device can be removed from the lock at the unlocked position or can be selectively set to be unable to be removed.

  Each storage compartment in a locker of a sports facility where multiple people use the same storage compartment, or a storage cabinet for personal belongings installed in various facilities or offices such as offices or schools When the personal belongings are accommodated in the door and the door is closed and locked, the use form in which the key of the lock is taken out and the user who has taken out the section manages the key is generally used.

  However, when the storage compartment is not used, the door lock is unlocked and the door can be freely opened and closed. At this time, the lock key of the door is always removed while being inserted into the key hole of the lock. It is necessary to be impossible. The reason for this is that when an unspecified person uses the same containment space at different times, if the key can be removed in the unlocked state, a key that can be removed due to mischief or mistakes will be brought back. This is because the storage compartment cannot be used.

  However, in the lockers and cabinets as described above, when each storage section of personal property is used exclusively for a specific individual, it is not necessary that the key cannot be removed at the time of unlocking. Rather, it is desirable to remove the key in order to prevent others from using their own storage compartment.

  Conventionally, as described above, there has been no lock device that can be selectively set in one lock device so that the key cannot be removed at the time of unlocking, or the key can be removed at the time of unlocking. Currently, two types of locks, a lock and a lock from which the key can be removed when unlocked, are prepared in advance, and one of the locks is selected and attached depending on the application.

  However, preparing two types of locks with specifications in advance is not only costly, but also the specification of the locks attached to the door after the cabinet is installed (the key can be removed when unlocked) When it is necessary to change the specifications of the type and the specification of the type that cannot be removed), extra locks and costs are required, such as changing each lock or replacing the cabinet with a lock with a different specification. There is a problem.

  Therefore, the subject of the present invention is that, in one lock, the specification of whether or not the key can be removed when unlocked can be selectively set to the lock, and the setting can be changed arbitrarily. An object of the present invention is to provide a lock device which can be used.

Configuration of the present invention lock device has been made for the purpose of solving the above problems, facilities the door is mounted on a door provided in the storage compartment, it is the lock before device to be unlocked, the keyhole the door A cylinder lock that is exposed to the front side of the door and is attached to the back surface of the door via an attachment member, a latch that is attached to an operating body for locking and unlocking the lock, and an operation end portion of the latch at the time of unlocking On the other hand, in the lock device comprising a latch operation control member that allows the latch to operate until the end of operation or prevents the operation of the latch before the end of operation , the cylinder lock and the latch The control member is covered with a rear cover including the mounting member of the cylinder lock, and a hole for operating the control member is provided in a portion corresponding to the control member of the cover. The latch for unlocking is operated on the control member by rotating or moving back and forth with respect to the installation surface of the mounting member in the cover and operating the control member from the operation hole. Select and set the action that allows operation to the end and the action that prevents the operation before the end of operation, and the latch operation at the time of unlocking can be removed from the cylinder lock and the key can be removed. it is characterized in that as cut with settings by selecting the disabled state.

  In the above-described lock device of the present invention, the latch is provided so as to perform a rotating operation or a sliding operation following the rotation of the operating cylinder (inner cylinder) of the cylinder lock.

  In addition, the control member for the latch operation is set by selecting a position that does not interfere with the latch that is provided on the mounting member of the cylinder lock and is rotated or moved forward and backward to interfere with the latch that performs the unlocking operation. An action that allows the latch to operate until the end of operation and an action that prevents the latch operation before the end of operation are provided so as to be selectable.

  The control member includes a type that changes the direction of the contact portion of the latch by rotation, a type that advances and retracts the contact portion of the latch to a different outer diameter by rotation, or a contact portion of the latch that rotates. There is a type that sets the contact position and the non-contact position with the latch, and any of these may be used in the present invention.

  The present invention relates to a lock device capable of opening and unlocking a door, a cylinder lock having a key hole exposed on the front side of the door and attached to the back surface of the door via an attachment member, and the unlocking and unlocking of the lock Allow the latch attached to the actuator to operate and the operating end of the latch when unlocked to allow the latch to operate to the operating end or prevent the latch from operating before the operating end A latching control member that can be operated, and operating the control member provided on the mounting member to remove the latching operation at the time of unlocking from a state in which the key is removed from the keyhole by the operation of the control member. Since either one of the impossible states can be selected and realized, it is not only highly useful and economical, but also highly convenient.

  Next, an embodiment of the lock device of the present invention will be described with reference to the drawings. In the attached drawings, FIG. 1 is a rear view of the main part of a door provided with an example of the lock device of the present invention, and FIG. 2 is placed in a state in which the key is removed by the control member provided in the first example device of FIG. 3 is a rear view of the main part, FIG. 3 is a rear view of the main part of the apparatus of the first example shown in FIG.

FIG. 9 is a front view of the main part of the third example of the apparatus, FIG. 9 is a front view of FIG. 8, FIG. 10 is a plan view of the third example of FIG. FIG.

  1 to 3, reference numeral 1 denotes a door formed by press-molding a steel plate or the like provided in an individual storage section such as a cabinet, and one side portion (side where no hinge is provided) of the back surface of the door 1. At the intermediate portion in the height direction, a cylinder lock 2 and a mounting portion 3a, 3b, which is substantially blade-shaped and integrated with the lock 2 for fixing the cylinder lock 2 to the back surface of the door 1, are mounted. A lock device R including a metal fitting 3 and a latch 4 fixed to the inner cylinder rotating on the rear end face side of the cylinder lock 2 with screws 4a or the like is provided. The latch 4 protrudes and retracts with respect to a latch receiver (not shown) provided on the door receiving side by the locking / unlocking operation, and acts as a kanuki that allows or rejects the opening of the door 1. Sometimes called.

  The lock device R is fixed to a mounting seat 5 formed on the back surface of the door 1 by a mounting bracket 3 integrated with a cylinder lock 2 having a latch 4, and the lock device R is entirely made of a plastic rear surface. Covered by a cover 6. As the mounting member for the cylinder lock 2 according to the present invention, in addition to the metal mounting bracket 3 described above, a mounting member made of plastic or the like can be used integrally with the cylinder lock 2.

  In FIG. 1, H is a window that also serves as a pulling handle pierced through the door 1, t is a door pad provided on the edge of the back surface of the door 1, and r is a moderation at the end of the door when the door 1 is closed. At the same time, the latch r is a free latch that keeps its closed state. The latch r is always pushed from behind by a spring force and is in a protruding state, and is provided so as to move backward when a large spring force is applied.

  The mounting bracket 3 illustrated in FIGS. 1 to 3 includes mounting blade pieces 3a and 3b and a metal body 3c having a substantially U-shaped cross section having the pieces 3a and 3b at the top and bottom, and is formed on the blade pieces 3a and 3b. The mounting holes 31a and 31b are fixedly coupled to the mounting seat 5. The cylinder lock 2 is integrated with the mounting bracket 3 on the inner side of the main body 3c, and the rear end of the inner cylinder (not shown in the figure, also referred to as a rotating cylinder or a working cylinder) is connected to the main body 3c. The rear end portion of the tongue-like latch 4 is fixed to the exposed portion by a mounting screw 4a. The front end side of the inner cylinder is provided on the front side of the door 1 with the front end surface of the inner cylinder exposed to form a keyhole.

  With the above configuration, when a key (not shown) is inserted into the keyhole on the front side of the cylinder lock 2 (exposed on the front side of the door 1) and rotated, the inner cylinder rotates 180 degrees in the illustrated cylinder key 2. The latch 4 is normally swiveled approximately 180 degrees. In the example of FIGS. 1 to 3, the posture in which the latch 4 is positioned on the right side with respect to the mounting screw 4 a is the locked state, and the state in which the latch 4 is positioned on the left side is the unlocked state.

The cylinder lock 2 is a so-called 180 degree rotation operation type, and if the latch 4 is on the right side or the left side in a substantially horizontal posture with respect to the mounting screw 4a, the key can be removed from the key hole, but not in the middle, although not shown. It is built as follows.
However, in practice, due to processing errors, assembly errors, etc., the key can be removed even if it is not horizontal if it is close to the horizontal posture (see FIG. 2), and the key cannot be removed if the angle becomes larger than that (see FIG. 3). ).
Therefore, in the present invention, a mechanism capable of selectively setting the unlocked state of the cylinder lock 2, that is, when the door 1 can be freely opened and closed, when the key can be removed and when it cannot be removed, is integrated with the cylinder lock 2. The metal fitting 3 is provided. Note that the present invention is not limited to the 180 ° operation angle of the above example, and can also be applied to, for example, a 90 ° or 270 ° rotation operation type.

  In the first example of the lock device of the present invention, as shown in FIGS. 1 to 3, the cylinder lock 2 is unlocked (the key inserted into the key hole of the locked lock is rotated 180 degrees) and the latch 4 is A knob-shaped rotating piece member 7 is provided as an example of a control member that abuts on the outer peripheral portion of the rotating latch 4 and prevents the turning of the latch 4 near the terminal portion that rotates.

  The rotary piece member 7 is a knob-like member formed by making the long diameter portion 7a and the short diameter portion 7b orthogonal to each other with respect to the rotation shaft 7c, and the short diameter portion 7b is positioned in the vertical direction (see FIG. 2, long diameter portion 7a). Can be removed at the time of unlocking, but the key cannot be removed even if the long diameter portion 7a is positioned in the vertical direction (see FIG. 3, the long diameter portion 7a is vertical).

  The piece member 7 is provided with a spring (not shown) for applying a tensile force to pull the piece member 7 toward the surface side of the mounting bracket 3 on the rotating shaft 7c, while the back surface of the long diameter portion 7a of the member 7 is provided. A small hemispherical projection (not shown) is provided on the surface of the metal fitting 3, and the concave portions 3c and 3d that receive the projection are arranged in a cross shape on the surface of the metal fitting 3. If the projection on the back surface is fitted into the set of two recesses 3c or 3d when rotated 90 degrees, the horizontal and vertical rotational positions of the long diameter portion 7a can be positioned semi-fixed. Even if the latch 4 is rotated and collides with the piece member 7, no positional deviation occurs. Thereby, the reliable positioning of the rotary piece member 7 and its effect | action can be ensured.

  FIGS. 4-7 shows the 2nd example of this invention lock device, and the screw member 8 provided as a control member replaces the rotary piece member 7 of a 1st example here. 4 to 7, the same reference numerals are used for the same members and parts as those in FIGS.

  The screw member 8 used in the examples of FIGS. 4 to 7 has a thick and large diameter head 8a and a male diameter that is smaller than the head 8a and is screwed into a female screw in a hole provided in the mounting bracket 3. It consists of a small diameter part 8b provided with a screw. Then, depending on the screwing depth (shallowness) of the screw member 8, the latch 4 that rotates at the time of unlocking comes into contact with the head 8a and stops rotating, or the latch 4 is latched by the small diameter portion 8b. The rotation angle at the time of unlocking the latch 4 is differentiated depending on whether the rotation of the latch 4 is blocked, and the unlocked state where the key cannot be removed and the unlocked state where the key can be removed can be selected and set.

8 to 11 show a third example of the lock device according to the present invention. Here, the latch member that is moved by the application and unlocking operation of the cylinder lock 2 is not the rotating latch 4 of the above example but a linear slide. A slide latch 41 that moves forward and backward is used.
For this reason, in the embodiment shown in FIGS. 8 to 11, in order to selectively set the unlocked state and the unlocked state when unlocking, is the interference with the rear end 41a of the slide latch 41 (preventing backward sliding)? Alternatively, as a control member that creates a state in which no interference action occurs, the entire length is a single-diameter screw, but the screw member 9 can select and adjust the interference or non-interference state depending on the screwing depth. Is used.

That is, if the screwing depth is reduced and the screw member 9 does not interfere with the rear end portion 41a of the slide latch 41 that moves backward by the unlocking operation, the slide latch 41 shown in FIGS. Since the slide is ready, the key can be removed from the key hole of the cylinder lock 2.
However, when the screw member 9 is screwed in deeply as shown in FIGS. 10 and 11, the rear end 41a of the slide latch 41 that moves backward is obstructed by the screw member 9 that is screwed in, and the slide slide 41 is further blocked. Therefore, the key cannot be removed from the keyhole of the cylinder lock 2.

  In the cylinder lock 2 having the slide latch 41 described above, an eccentric pin is provided on the rear end surface of the rotating inner cylinder, and the pin is loosely fitted on the surface of the slide latch 41 facing the eccentric pin (eccentric cam). If a vertical groove (cam groove) is formed, the slide latch 41 can slide in the left-right direction in the figure by the rotation of the inner cylinder.

  In the above embodiment, the rotary piece member 7 and the screw members 8 and 9 are provided so as to be inside the rear cover 6, and an operation driver bit or the like is provided at a portion corresponding to each of the members 7 to 9 of the cover 6. An operation hole 6a into which the operation tool can be inserted is provided, and the operation tool is rotated by the operation tool such as the bit. This is because if the heads of the members 7 to 9 are exposed to the outside of the rear cover 6, the setting for enabling or disabling the key may be changed without permission.

  However, in the present invention, the above setting can be changed without using a tool. In this case, as an example, the operation hole 6a of the cover 6 can be made large so that a fingertip can be inserted so that the members 7 to 9 can be directly operated from the outside of the rear cover 6. If the operation heads (not shown) are formed on the members 7 to 9, and the members 7 to 9 are formed so that the operation heads are located outside the cover 6. Good.

  The present invention is as described above, and in the lock device that can be opened and unlocked, the lock device exposes the keyhole to the front side of the door and is a cylinder integrated with the mounting member on the back surface of the door. A lock, a latch attached to an actuating member for locking and unlocking in the cylinder lock, and an operating end portion of the latch at the time of unlocking, allowing the latch to operate to the operating end, or A latch operation control member capable of preventing the operation of the latch before the end of operation, and by operating the control member provided on the mounting member, the key is removed at the time of unlocking in one lock device. Since it is possible to selectively set a specification that can be used and a specification that cannot be removed, a lock device that is extremely useful in terms of usability and cost can be provided.
