Description

Description: BACKGROUND OF THE INVENTION [0001] The present invention relates to a coin locker,
The present invention also relates to a lock mounting device suitable for mounting on a wooden door of a locker. 2. Description of the Related Art A lock in a conventional coin locker, for example, made of metal, has a lock casing and a locking flange protruding from the outer periphery of the front end thereof. The lock casing is pushed into the hole until its locking flange abuts the front of the door. As a result, the lock is fitted and fixed to the mounting hole of the metal door so as not to easily fall off by using its elasticity. However, when a lock in a conventional coin locker is mounted on a wooden door,
If the lock casing is simply pushed into the mounting hole opened in the wooden door until the locking flange abuts on the front of the door and fitted, the rattling cannot be avoided. That is, there is a problem that the lock casing is easily pulled out from the place where the fitting state is unstable by pulling the lock casing toward the user. The present invention has been made in view of the above-mentioned problems of the conventional technology, and has been developed in consideration of the above-mentioned problems.
In addition, a synthetic resin support frame fitted with a metal support plate having a fitting hole slightly smaller than the mounting hole of the wooden door of the locker is fixed in advance to the mounting hole of the wooden door, and the support plate is fitted. After fitting the lock casing into the mating hole, screw the screw through the holding plate into the screw cylinder integrally projecting on the back side of the support frame, and fix the lock casing to the wooden door by configuring The locker lock can be fitted to the mounting hole opened in the wooden door with one-touch operation, and it can be firmly fitted and fixed without looseness so that it does not fall off easily. It is intended to provide a device. [0005] In order to achieve the above object, an apparatus for mounting a lock according to the present invention is provided with a mounting hole formed through a wooden door of a coin locker or other locker, and a lock is formed in the mounting hole. In a device for attaching a lock to a wooden door by fitting a casing, a metal support plate having a fitting hole slightly smaller than a mounting hole of the wooden door, and a fitting hole slightly larger than the fitting hole of the support plate. Having a fitting recess of the support plate on the back side, a peripheral portion of a fitting hole of the support plate fitted into the recess, formed so as to protrude inside the fitting hole,
A support frame made of synthetic resin in which a plurality of screw cylinders are integrally protruded, and a rear portion of a flange formed at the front end of both side plate portions, at a distance slightly larger than the plate thickness of the support plate. A lock casing provided with a locking projection and an elastic locking piece, and a holding plate having screw holes formed at both ends at predetermined intervals so as to correspond to the screw cylinder, With the support plate fitted in the fitting recess of the support frame, each screw cylinder is inserted into an engagement hole provided continuously with a corner of the mounting hole of the wooden door, and at the rear ends of the screw cylinders on both sides, The holding plate is brought into contact with the holding plate via the back side of the wooden door, and the supporting frame is fixed together with the supporting plate to the front surface of the mounting hole of the wooden door with a screw screwed into a screw cylinder from a screw hole of the holding plate. , Into the mounting hole of the wooden door through the fitting hole of the support plate, Engagement-detachably oppression the fitting hole peripheral portion of the support plate by a flange and the locking projection and the elastic latching pieces of the single front end, is characterized in that so as to clamp. After inserting a plurality of screw cylinders of the support frame with the support plate fitted on the back side into the mounting holes of the wooden door, press the holding plate through the wooden door on the back surfaces of the screw cylinders on both sides. The support plate and the support frame are fixed to the wooden door by screwing the screws into the respective screw cylinders from the screw holes of the holding plate. When the lock casing is pushed into the mounting hole through the fitting hole inside the support plate in a state where the support plate and the support frame are fixed to the front portion of the mounting hole of the wooden door in advance, the front end of the lock casing can be obtained. The lock casing is resiliently pressed and clamped by the periphery of the fitting hole of the support plate fixed to the front surface of the wooden door between the flange and the locking projection and the elastic locking piece projecting from the rear portion. In this manner, the entire lock equipped with the locking mechanism in the lock casing cannot be easily pulled out from the mounting hole of the wooden door because it is firmly fixed to the metal support plate.
