[Structure] A cylinder lock 1 having a magnetic ring 2 fitted and adhered to a front end portion 1a of an inner cylinder is attached to a front surface 1 of the front end portion 1a of the inner cylinder.
It is attached to the attached body 4 such that c is located inward by the thickness dimension of the magnet plate 3 described later. Then, a circular magnet plate 3 having the same diameter as that of the outer cylinder front end 1b is magnetically attached to the magnetic ring 2, and the magnet plate 3 covers the insertion hole 4a of the cylinder lock 1 formed in the body 1 to be mounted. The lid is closed on the same surface as the surface of the mounting body 1.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a concealing device for a cylinder lock. This concealment device makes the barrel tip portion 2 of the master cylinder lock attached to the door of the rental rocker, for example, invisible from the outside.

[0002]

[Prior art]

 Conventionally, a master cylinder lock used by a locker administrator is attached to a door of a locker for rent when a locked door is to be emergency unlocked. Then, as shown in FIG. 4, the cylinder lock is attached by inserting the outer cylinder portion 11 of the cylinder lock 10 into the door 12 through the lock mounting hole 13 and the rear surface of the flange portion 14 at the front end of the outer cylinder to the door plate. It is inserted until it comes into contact, and a nut 15 is arranged on the back surface of the collar portion 14 via a door plate, and is screwed.

[0003]

[Problems to be solved by the device]

 As described above, the master cylinder lock is used for emergency unlocking such as a customer lock with a spare key locked and a locked electric lock. Therefore, it is rarely used in normal times. For this reason, users of rental lockers and the like felt uncomfortable because the barrel tip of the cylinder lock that they did not use was exposed on the outer surface of the door.

The applicant of the present invention exposed all the cylinder tip portions of the cylinder locks of the lockers that conventionally required by the applicant to require the master cylinder lock. By not exposing the locker, I felt that the locker users would not feel uncomfortable, the door surface would be simple, and the locker would be excellent in design. Then, a lock concealing device (utility model application publication No. Sho 63-91664) in which the lock is invisible from the outside was provided. However, in the present invention, a lock is formed on a crown that rotates and a door is opened by using the crown. It was equipped with a lock head protruding from the surface, and was mainly suitable for concealing customer locks.

The present invention has been made in view of the above problems, and an object of the present invention is to completely prevent a master cylinder lock attached to an attached object such as a locker door from being seen from the outside. It is to provide a concealing device for a cylinder lock.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, a concealing device for a cylinder lock of the present invention comprises: (a) a cylinder lock; and (b) a magnetic ring fitted and bonded to the front end of the inner cylinder of the cylinder lock. C) A circular magnet plate formed to have the same diameter as the front end of the outer cylinder of the cylinder lock, and (d) a front surface of the front end of the inner cylinder being positioned inward with the same dimension as the thickness of the magnet plate. , A cylinder to which the cylinder lock is attached, and the magnetic ring fitted and adhered to the front end of the inner cylinder to attach the cylinder lock to the cylinder to be attached, and then the magnet plate. The magnetic ring is magnetically attached, and the insertion hole of the cylinder lock in which the magnet plate is bored in the attached body is closed on the same surface as the surface of the attached body.

[0007]

[Action]

 The body to which the cylinder lock is attached is designed so that the cylinder lock can be attached by positioning the front surface of the front end of the inner cylinder of the cylinder lock inside the same size as the thickness of the magnet plate described later. Therefore, if a cylinder lock with a magnetic ring fitted and adhered to the front end of the inner cylinder is attached to the body to be attached, the front surface of the front end of the inner cylinder of the cylinder lock will be inward of the body to be attached by the thickness of the magnet plate described below. Located in. When the magnet plate described later is magnetically attached to the magnetic ring, the magnet plate is formed into a circular shape having the same diameter as the front end of the outer cylinder of the cylinder lock. The cylinder lock insertion hole formed in the attached body is closed on the same surface as the surface of the attached body to conceal the cylinder lock.

[0008]

Embodiments of the present invention will be described with reference to the drawings. 1 and 2, 1 is a cylinder lock, 2 is a magnetic ring, 3 is a magnet plate, and 4 is a body to which the cylinder lock 1 is attached. The cylinder lock 1 is made of brass and is a combination of an outer cylinder and an inner cylinder. Then, the cylinder lock 1 is screwed by a nut 5 via an auxiliary body 4a to which a flange portion of a front end portion 1b of the outer cylinder is attached integrally with an attached body 4. The magnetic ring 2 is made of paramagnetic metal, and is fitted and adhered to the inner cylinder front end 1a of the cylinder lock 1.

The magnet plate 3 is formed in a circular shape having the same diameter as the outer cylinder front end portion 1b of the cylinder lock 1. A seal 3b of the same color as the surface of the body 4 to be attached is attached to the surface of the magnet plate 3, and a pin insertion hole 3a is formed in the center of the surface. The mounted body 4 is a door of a steel locker, and a lock insertion circular hole 4a having the same shape as the magnet plate 3 is formed in the mounting portion of the cylinder lock 1, and an auxiliary body having a U-shaped cross section is formed on the back surface thereof. 4a is welded, the auxiliary body 4a is provided with a screw-in hole 4b of the outer cylinder, and the front surface 1c of the front end 1a of the inner cylinder of the cylinder lock 1 is attached to the inside of the door by the thickness of the magnet plate 3. It is designed so that the cylinder lock 1 can be mounted in the one-sided position.

In this way, the cylinder lock 1 in which the magnetic ring 2 is fitted in the inner cylinder front end portion 1 a and adhered is attached to the attached body 4 as illustrated. When the magnet plate 3 is magnetically attached to the magnetic ring 2 adhered to the cylinder lock 1, the magnet plate 3 closes the lock insertion hole 4a of the mounted body 4. When the lid is closed in this way, the thickness of the magnet plate 3 is the same as the distance between the surface 1c of the cylinder front end 1a and the surface 4c of the mounted body 4, so that the surface of the magnet plate 3 is mounted on the mounted body 4. The surface of the cylinder lock 1 is flush with the surface 4c, and the cylinder tip portion of the cylinder lock 1 is completely hidden so that it cannot be seen from the outside.

When removing the magnet plate 3 with the lock insertion hole 4a of the attached body 4 closed, the coil type key holder 5 as shown in FIG. 3, for example, is inserted into the pin insertion hole 3a of the magnet plate 3. It is possible to pull out one end portion of and to insert and hook the pulled-out pin tip 5a. When the attached body 4 is made of wood, a sticker having a bare pattern is adhered to the surface of the magnet plate.

[0012]

[Effect of device]

 The present invention has the following remarkable effects. (A) The structure is simple and the manufacturing is easy. (B) A magnet plate magnetically attached to the magnetic ring that is fitted to the front end of the inner cylinder of the cylinder lock closes the insertion hole of the body to which the cylinder lock is inserted, on the same surface as the surface of the body to be mounted. However, since the surface of the magnet plate has a sticker with the same color and pattern as the surface of the body to be attached, the cylinder lock is completely hidden and cannot be seen from the outside. Then, the discomfort given to the locker user is eliminated. (C) Cylinder locks are not exposed on the doors of lockers, etc., and the door surface is simplified, making the lockers, etc. excellent in design and improving the price of lockers, etc.
