  However, by unlocking the flat key plate displaying the number and name into the lock and configuring the flat key plate so that it cannot be removed in the unlocked state, it is possible to manage the key and manage the user. There was nothing related to key management tools for specific purposes.

  In addition, there is no simple instrument that can be locked to the extent that it can be picked up with a finger so that neither the key holder nor the flat key plate will accidentally pop out of the lock during the unlocking / locking operation. It was.

  Accordingly, an object of the present invention is to provide an epoch-making key management tool that can achieve the above object.

The present invention provides a mechanism for unlocking by inserting a flat key plate to lock body, the lower circumferential frame portion of the central space portion of Urafutatai the base of the elastic member disposed within the凾shaped Urafutatai right and left base portions engage placed on, and the slope resilient member subsequent to this the central concave hole which the tip portion of the central protrusion to protrude obliquely upward is provided at one end of the bottom of the flat key plate as it may apart sliding contact against the central groove provided at the parts and Shomoto interval, inserting the key holder to the insertion port formed in a lower central portion of the front cover plate of the front lid member consisting凾状the it is to the central protrusion of the elastic member of the back cover body so allowed to leave from the center groove of the flat key plate.

Further, the present invention is to install a plurality of key management tools as described above in parallel at a predetermined location.

  First, even when used in a warehouse or any other place, the key can be stored and handled in a necessary place with peace of mind, which is extremely convenient.

  Secondly, since a predetermined flat key plate is stored only by a specific handler, the use of the flat key plate is not confused, and the handler can be held responsibly.

  Third, when the flat key is inserted, the key holder can be pulled out, and when the key holder is inserted, the flat key plate can be released and pulled out, and both actions can be performed easily and smoothly.

  Fourthly, it is possible to reliably prevent the key holder and the flat key plate from popping out by the operation of the elastic member inside the lock body at the time of unlocking or locking operation.

  To unlock the key holder from the lock body, a flat key plate is inserted into the upper-end concave portion of the front cover body of the lock body, and the elastic body is pressed from above. Then, since the elastic body moves down and contracts via the bullet unit integrated with the mounting portion, the elastic body communicates with the key insertion port of the front cover plate in which the lock portion of the key holder has been the suppression portion of the key holder. It comes off from the opening part and intermediate | middle recessed part of an attachment part, and will be in an unlocked state. Therefore, the key holder can be extracted by this.

In this case, at a central concave hole and the inclined surface portion and Shomoto interval subsequent thereto the tip portion of the central protrusion is provided at one end portion of the rear surface portion of the flat key plate of elastic member locking portion of the key holder had oppressed The flat key plate is fixed so that it cannot be removed because it slides and joins the central groove provided .

  Next, in order to lock the key holder, the tip lock portion of the key holder is inserted from the key holder insertion hole of the front cover plate of the front cover body of the lock body. Then, when the lock part of the key holder is inserted into the opening part of the elastic body, the lock part is inserted into and engaged with the intermediate recess on the lower side from the opening part.

  At this time, since the lock part of the key holder presses a part of the central protruding piece of the elastic member, the tip of the central protruding piece is detached from the central concave groove of the engaged flat key plate, and the flat key plate is It is ready to be pulled out and locking is completed.

  In addition, when the flat key plate is inserted in the unlocked state, the pop-up prevention part provided around the tip lock part of the key holder prevents the key holder pop-out elastic part provided inside the lock body from protruding. It comes to lock.

  Conversely, when the key holder is inserted into the locked state, the tip of the central protrusion of the elastic member inside the lock body is not attached to the flat key plate so that the flat key plate does not pop out due to the elastic force of the elastic member. Lock in the groove to prevent popping out.

  An arbitrary number sticker or the like is attached to the display unit provided on the flat key plate.

  Coloring is performed (for example, six colors) so as to be grouped to improve the classification / identification function of the flat key board.

  The operation of the above mechanism will be described more specifically and in detail with reference to FIG. 4 as follows.

  FIG. 4 is a longitudinal sectional view showing an assembled state in which the constituent members are housed in the lock body composed of the front and back lid bodies 1 and 11 shown in FIGS. 1 and 2, and in this state, the key holder The operation when 31 and the flat key plate 33 are used is shown. In the drawings (a) to (d), the left side is the front direction.

From the key storage location that is parallel as shown in now to FIG 5, when the person in charge bring the key of "warehouse 3", a flat key plate 33 personnel to Tokoro lifting, Omotefuta for unlocking It is inserted into the upper end concave portion 13 of the front lid plate 12 of the body 11.

  FIG. 4A shows an initial state where a flat key plate for unlocking is inserted, and FIG. 4B shows a state after the flat key plate is pressed in the direction of the arrow.

When the user presses the inserted flat key plate 33, recessed holes 34 of the central portion of the flat key plate, the slope portion 35 and the recessed groove 3 6 moves, by projecting from the lower portion of Urafutatai 1 consisting a box shape The distal end portion of the central projecting piece 9 ′ of the elastic member 9 is slidably engaged with the concave hole 34, the inclined surface portion 35 and the central concave groove 36 and stopped.

At the same time, the lock portion 32 of the key holder 31 engaged with the intermediate concave hole 29 ′ with the opening portion 29 is released by pressing the elastic body 26 installed on the front cover plate 11 against the bullet unit 27. From (b), the key holder can be pulled out in the direction of the arrow.

In this case, suppression of the central protrusion 9 'of the elastic member 9 the locking portion 32 of the key holder 31 has been repression is released, because engages the central recessed groove 3 6 Hirakagiban 33, a flat key plate it will not be withdrawn.

(c) and (d) are drawings showing the attachment and storage state of the key holder 31 opposite to the extraction action shown in (a) and (b) above, and are the opposite of (a) and (b) above.
