Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is applied to a large number of users such as lockers installed in schools, factories, offices, etc., or rental lockers installed in various sports or leisure facilities. The present invention relates to a lock device suitable for engaging and disengaging a padlock to be brought to.

[Conventional technology]

A locker that locks and unlocks the padlock brought by each user without providing a lock on the locker itself is not only low in equipment cost but also easy to maintain the locking device, and is a padlock type. There is an advantage that it can be used without any restrictions.

There are several examples of this type of conventional technique. For example, as the first conventional technique, Japanese Patent Application No. 55-98118 (Actual No. 57-2).
(1750) micro film, there is a prior art, and this prior art allows a hook ring adapted to insert a padlock to be inserted and removed so that the hook body will be in a hooked state when it projects. At the same time, the retaining ring is prevented from retracting by inserting the bolt into the protruding retaining ring.

Also, as a second conventional technique, there is a prior art described in the microfilm of Japanese Utility Model Application No. 52-42080 (Japanese Utility Model Publication No. 53-140697). The padlock is made extremely large to accommodate the padlock, and the padlock is used in a state where it does not protrude forward.

[Problems to be solved by the device]

In the first prior art described above, the padlock itself is attached to the outside of the locker by hanging the padlock on the outside of the door by hanging the padlock outwardly on the lock. In particular, when a thick padlock such as a code lock having a plurality of rotating rings is applied, the padlock projects greatly outward and a passerby or other user of the locker. There is a drawback that is an obstacle.

In the second prior art, the padlock itself does not project to the outer surface of the locker, but the latch driving actuating plate and the pusher piece as its knob are used to connect the handle part and the padlock in the recess of the mounting frame. Due to the structure provided at the intermediate position and in which the operating plate and the pushing piece slide, it is necessary to make the concave portion of the mounting frame large, and therefore the mounting frame and the entire equipment are remarkably large.

In both prior arts, since the handle piece is in a usable state when it is locked with a padlock, and the structure keeps the usable state even though there is no need to open the door, In the stopped state, the door opening operation is apt to be performed undesirably, the equipment may be damaged, and the space is wasted.

Therefore, an object of the present invention is to minimize the outward protrusion amount of the padlock even in the locked state, to reduce the size of the mounting frame, and to make the structure difficult to operate with respect to the handle piece in the locked state. The object of the present invention is to provide a locking device that satisfies the above requirements.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention is, in the invention of claim 1, fixed to a door which is openably and closably mounted on the main body, and which is used for both storage of a padlock in a locked state and insertion of a fingertip. In addition to the recessed part of the mounting frame, the back of the mounting frame is provided with a locking mechanism that has a locking body that advances and engages behind the end edge of the main body, and as a locking mechanism, there is a through hole that is suitable for inserting the padlock through the hole. With the actuating body integrally provided with the formed snap ring and the handle piece being pivotally stopped at the middle portion thereof under the horizontal axis, the snap ring is retracted or protrudes outward, The operating body and the latching body are associated with each other by an interlocking mechanism so that the latching body is advanced and retracted in conjunction with the turning of the operating body. Enters the recess and is hidden behind the locked padlock. And wherein the digit.

Further, in the invention of claim 2, a mounting frame is fixed to a door which is openably and closably provided on the main body, and the mounting frame is provided with a recess for both padlock accommodation and fingertip insertion in a locked state, The back has a locking mechanism that has a locking body that advances and engages behind the end edge of the main body, and as a locking mechanism, a locking ring that is suitable for inserting the padlock into the padlock is used when the locking ring protrudes. The hook piece is fixed inwardly on the side of the recess at a position approaching the side of the padlock in the locked state, and the hook piece and the padlock are locked together. The feature is that the fingertip is not inserted in the middle.

[Action]

In the locked state, most of the padlocks are recessed in the mounting frame to reduce the amount of protrusion to the outside, and the clasp for opening the door is hidden or invalidated by the padlock, and the equipment is small in size. Can be realized.

[Embodiment] Hereinafter, an embodiment of the locking device of the present invention shown in the drawings will be described in detail.

The illustrated embodiment is an example in which the locking device of the present invention is attached by utilizing a handle portion of a door which is openably and closably provided on a metal locker body.

To be more specific, the door 2 is provided on the main body 1 of the metal locker so as to be openable and closable, and the vertical rectangular mounting frame 3 is fitted and fixed to the door 2 from the outside, and the latch mechanism 4 and the display unit 5 are mounted on the mounting frame 3. Further, in addition to providing the hooking mechanism 6, there is provided a recessed portion 7 for accommodating the padlock A and for inserting the fingertip, and a hook piece 8 projecting from one side edge of the recessed portion 7. 6 is an intermediate portion of an actuating body 10 in which a retaining ring 9 having a through hole adapted to the insertion of the bolt B in the padlock A and a handle piece 8 on the opposite side of the retaining ring 9 are integrally provided. At the turning position, while being pivotally stopped by the pin 11 on the left-right axis In addition to allowing the ring 9 to recede into the mounting frame 3 or to project outward, a rod-shaped driving body 12 is projectingly provided behind the actuating body 10, while the mounting frame 3 is provided with a back portion thereof. While the plate-shaped locking body 14 pivotally stopped by the pin 13 is provided, it is possible to advance and engage behind the end edge 15 of the body 1 of the rocker while the locking body 14 is passive. A long hole 16 is formed, the driving body 12 is engaged with the long hole 16, and the driving body 12 and the long hole 16 constitute an interlocking mechanism, and the hooking body 14 pivots the operating body 10. The handpiece 8 is integrally provided on the actuating body 10 so that the retaining ring 9 can be projected by a pressing operation against the same. To fourth
As shown in the figure, the retaining ring 9 of the actuating body 10 is retracted inward of the mounting frame 3 and the hooking body 14 interlocked with the turning of the actuating body 10.
While the door is kept in the released state, the door is kept closed by the temporary locking action of the latch mechanism 4, or the handle piece 8 of the actuating body 10 can be opened by pulling it by the fingertip, and the lock can be opened. To stop, the front end of the hooking body 14 is pushed behind the end edge 15 of the rocker body 1 via the driving body 12 as shown by the chain line in FIGS. At the same time, the snap ring 9 is projected forward, and the snap ring 9 of the padlock A such as a code type is inserted into the projecting snap ring 9 and locked to lock the snap ring 14 by preventing the snap ring 9 from entering. State to prevent the door from opening,
For unlocking, the padlock A is removed and the retaining ring 9 is pushed in or the handle piece 8 is pulled to restore the retaining body 14 to the position separated from the back of the end edge 15 of the rocker body 1 by the drive body 12. I will let you.

As auxiliary equipment for stably maintaining the operating body 10 and the hanging body 14 in both the locked state and the unlocked state, the protrusion 17 of the operating body 10 is provided so as to protrude from the vicinity of the pin 11, and It is desirable to provide a spring 18 that constantly pushes toward the base end at the end of the protrusion 17, and as the display portion 5 provided on the mounting frame 3, a shallow recess 19 is provided on the upper portion of the mounting frame 3 as shown in the figure. It is preferable that the stoppers 0 and 20 are provided in the front portion of the peripheral edge of the recess 19 so as to face each other, and the bottom wall near the one side of the recess 19 is provided with an insertion hole 21 penetrating rearward.

It is desirable that 24 is projected from the mounting frame 3, and a lid plate 25 is removably attached to the back of the operating body 10 provided on the mounting frame 3.

Further, in the embodiment shown in FIGS. 7 to 9, the actuation body 10 and its related parts are provided under the vertical axis and
In the retaining ring 9 of 10, a mounting frame 3 is formed so that a portion of the padlock A closer to the end different from the apex of the canopy B is made to correspond, and a recessed portion 7 is formed for both padlock accommodation and fingertip insertion in the locked state. In addition to the above, a hook piece 8'fixed inward is provided on the side of the recess 7 in the mounting frame 3 without providing a hook piece on the actuation body 10, and particularly, the hook piece 8'and the padlock A The state in which the fingertip cannot be inserted is kept in the middle of the above, and the display unit 5 is omitted, and since there is no difference in nature from the above embodiment except for the handhold portion, the same reference numerals are given to the same portions. The description is omitted.

〔effect〕

As described above, according to the present invention, the padlock A in the locked state is provided based on the simple structure by providing the mounting frame 3 with the recess 7 which allows most of the padlock A to be retracted when locked. The amount of protrusion of A to the outside is reduced, and the actuating body 10 in which the retaining ring 9 and the hook piece 8 are integrally provided is pivoted on the horizontal axis in the middle portion with the hook piece 8 facing downward. Since it is provided so as to be stopped, the clasp piece 8 is hidden behind the padlock A in the engaged state to prevent the manipulation on the clasp piece 8 and to ensure that an unnecessary door opening operation is performed in the locked state. Can be prevented.

In addition, the actuating body 10 having the retaining ring 9 as the hooking mechanism 6 is pivotally locked on the vertical axis, and the hooking piece 8'appears at a position approaching the side of the padlock A in the locked state. Recess 7
Since it is provided so as to be fixed inwardly on the side of the padlock, the side portion of the padlock A prevents the operation of the handle piece 8'in the locked state, and the door is unnecessarily opened in the locked state. Can be prevented.

In particular, since there is no need to use the claw piece 8 in the locked state, it has two functions of inserting a fingertip for operating the claw pieces 8 and 8'and accommodating the padlock A. This is realized by the efficient use of one recess 7, so that the entire equipment such as the mounting frame 3 can be remarkably downsized.
