DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tray used in a remotely operated tray safe deposit box.

Traditionally, trays used in safe deposit boxes have a padlock attached to them separately from the customer lock attached to the door of the safe deposit box, and the customer needs two keys, one for the customer lock and one for the padlock. When storing, there are many problems caused by forgetting to lock the tray, and there are many opportunities for keys to be lost. This is especially a concern in the case of remote-controlled self-service safe deposit boxes.

This invention is a key for a customer lock, and after unlocking and unlocking the customer lock, the key can be used to open the lid, and even if you forget to lock the lid, it can be automatically locked to prevent trouble from occurring. The purpose is to reduce the chance of losing the key by using only one key, and to reduce management concerns in remote self-service operations.

For this purpose, the present invention is provided with a customer lock consisting of a storage body bolt that engages and disengages from the storage body to unlock and lock it, and a tongue bolt that engages and disengages from the lid body to unlock and lock the lid body. The customer lock is configured such that the operation of one key lever operated with the key of the customer lock causes the opening operation of the storage body bolt and the opening operation of the tongue bolt following the opening operation of the storage body bolt. Moreover, the lid body and tongue bar are characterized in that they are automatic locking locks.

Hereinafter, the present invention will be explained in detail based on preferred embodiments shown in the drawings.

An enlarged base portion 31 in which the base end portion located inside the customer lock of one storage body bolt 3 is made wider than the lock body 30 including the above-mentioned protruding and retracting tip portion and has a thinner wall thickness.
It is as follows. A guide hole 32 is formed approximately in the center of this widened base 31, and the lower tip is connected to the bolt 3.
A bearing portion 33 is provided so as to protrude in the opposite direction. In the figure, reference numeral 12 denotes a link, whose approximately central portion is rotatably supported 12' on the immovable part of the lock main body 2', one end is rotatably supported 33' on the bearing 33, and the bottom end is rotatably supported 12' on the fixed part of the lock main body 2'. It is pivotally supported 34' at the base of the other body lock 3'. In this case, as shown in the figure, it is preferable that the upper part of the base of the storage body bolt 3' is protruded to form a bearing part 34, and that the link 12 is supported pivotally 34' by the bearing part 34.
Since it is configured in this way, the storage body lock 3 and the storage body lock 3' operate in conjunction with each other, and their moving directions are opposite to each other. The guide hole 32 has a substantially semicircular upper part and a rectangular lower part, and at this semicircular part, the periphery of the tip of a key screw, which will be described later, comes into contact with the housing lock 3, and the rectangular shape The periphery of the tip of the key screw does not come into contact with the periphery of the key screw. In the figure, reference numeral 10 denotes a protrusion formed protruding from the joint between the bolt body 30 and the widening base 31 of the housing body bolt 3, and is provided integrally with the housing body bolt 3 from the bolt body 30 toward the widening base 31 side. . In addition, 35 in the figure is
This is a long hole formed in the widened base 31.

In the figure, 7 is a tumbler rotatably supported by a shaft 7' on the immovable part of the lock main body 2', and a notch 9 is formed at a position facing the protrusion 10 of the storage body lock 3 when rotated at an appropriate angle.
Due to its own weight or by applying spring elasticity, the notch 9 is normally located at a position where it does not face the protrusion 10. Further, the width of this notch 9 is sufficient to receive the protrusion 10. The lower edge of tumbler 7 is
It is designated as inner meridian 8, which is the route for key 6. That is,
The inner diameter 8 has a surface shape that matches the key thread shape of the regular key 6, and allows the key to be turned if it is a regular key 6, but cannot be turned if it is an incorrect key. .

Reference numeral 11 in the figure is a key screw, which is provided on the customer lock body 2' so that it rotates in conjunction with the rotation of the key 6 inserted into the customer lock 2. This key screw 11 is positioned in the guide hole 32 of the widened base 31 of the housing lock 3, and when the key screw 11 is rotated, the radius of the circle that is the trajectory drawn by the tip of the key screw 11 is The radius of the semicircle that is the shape of the upper part of the guide hole 32 is appropriately made smaller.

In the figure, reference numeral 4 denotes a tongue bar, which is capable of retracting and protruding from the outer peripheral surface of the passenger lock 2, and when protruding, engages with the front end 19 of the lid 5 to maintain the state in which the lid 5 closes the tray 1.
The tongue bar actuating plate 13 controls the movement of the tongue bar 4 into and out.
A key screw receiving pin 1 is rotatably supported on an immovable portion of the lock main body 2' and engages with the key screw 11.
4 and a tongue lock operating pin 15 that engages with the tongue lock 4 are provided protrudingly.
When engaged with the tongue bar, the tongue bar operating pin 15 and the tongue bar 4 engage with each other. A spring 16 is interposed between the tongue bolt 4 and the lock main body 2' below the tongue bolt 4,
The restoring force of the spring 16 is applied in the direction in which the tongue bar 4 protrudes from the lock 2.

The lid 5 of the tray 1 is attached to the main body of the tray 1 with a hinge 17, and the supporting portion of the hinge 17 on the tray 1 main body side is slidable with respect to the tray 1 main body. Also, for example, the tray 1 of the hinge 17
By wrapping a spring around the support rod on the main body side, etc.
It is desirable to provide spring elasticity or the like so that the lid body 5 always slides in a direction away from the main body of the tray 1. Further, reference numeral 18 in the figure is a handle portion recessed in the lid body 5.

The operation of the present invention with the above configuration will be explained below.

When the tray 1 is fixed to the storage body 25,
Each part of the passenger lock 2 is in the state shown in FIG. 3, and the tips of the body bolts 3, 3' are in a state of protruding from the outer peripheral surface of the tray 1, as shown in FIG. The tips of the protruding body bolts 3, 3' fit into holes (not shown) formed in the body 25, thereby fixing the tray 1 to the body 25. Further, since the front end 19 of the lid 5 of the tray 1 is engaged with the tongue bar 4 of the passenger lock 2, the tray 1 is in a closed state.

Insert the key 6 through the keyhole of the customer lock 2. If the key 6 is a regular key 6, the shape of the key ridge and the surface shape of the inner diameter 8 of the tumbler 7 match, so insert the key 6 clockwise in FIG. 3. It is permissible to turn the By the rotation of the key 6, the tumbler 7, which is rotatably supported 7' on the lock main body 2', is rotated by an appropriate angle, and the notch 9 formed in the tumbler 7 is inserted into the protrusion 10 of the storage body lock 3.
position it in a position facing the Then, when the key 6 is rotated, the peripheral edge of the tip of the key screw 11 that rotates in conjunction with the key 6 comes into contact with the inner surface of the guide hole 32 formed in the widened base 31 of the storage body bolt 3. Rotate and
This causes the storage body bolt 3 to be pushed in the upper right direction in FIG. 3. However, as described above, since the notch 9 of the tumbler 7 is positioned facing the protrusion 10 of the storage body bolt 3, the above-mentioned rightward pushing movement is permitted. Also, due to the movement of the body lock 3, the other body body lock 3', which is connected to the body body lock 3 via the link 12,
It will move in the opposite direction to the storage body bolt 3, that is, to the left in FIG. As the storage body bolts 3, 3' move, their tips are retracted from the outer peripheral surface of the tray 1, so that the tray 1 can be pulled out from the storage body 25.

When the body bolts 3, 3' are retracted from the outer peripheral surface of the tray 1, each part of the customer lock 2 is in the state shown in FIG. That is, the tongue bolt 4 is still protruding from the lock 2 and engaged with the front end 19 of the lid body 5, and the key screw 11 is in contact with the key screw receiving pin 14 of the tongue bolt operating plate 13. be.

When the key 6 is further turned from this state, the key screw 11
presses down the key screw receiving pin 14, so the tongue lock operating plate 13 rotates, and the tongue lock operating pin 15 protruding from the tongue lock operating plate 13 pushes down the tongue lock 4 (as shown in the fifth figure). When the tongue bolt 4 is pressed down,
Since the front end 19 of the lid 5 is disengaged from the tongue bar 4, pushing the lid 5 toward the rear end 20 will open the lid 5. Furthermore, if the user releases the key 6 after opening the lid body 5, the tongue bolt 4 will protrude from the lock 2 due to the restoring force of the spring 16 located below the tongue bolt 4.

As described above, after opening the lid 5 and completing tasks such as taking in and taking out valuables, the tray 1 is closed by pushing down the lid 5 and pulling the lid 5 toward you. That is, by pulling the lid 5 toward you, the front end of the lid 5 comes into contact with the tongue bar 4, and the spring 16
The tongue bar 4 is pushed down against the restoring force, and as it continues to be pulled forward, the front end 19 of the lid 5 passes over the tongue bar 4, the tongue bar 4 protrudes again, and the lid 5 closes the tray 1. This is what you will do.

When the tray 1 is stored in the storage body 25 without closing the lid 5, the tray 1 can be automatically closed by pushing the tray 1. That is, by pushing the tray 1, the rear end 20 of the lid 5 comes into contact with the back plate 21 of the storage body 25, and if the tray 1 is pushed further, the lid 5 is pushed forward, so that the front end 19 of the lid 5 and The tray 1 is closed by engaging the tongue bar 4.

Then, after placing the tray 1 in the storage body 25, if the key 6 is turned in the opposite direction to the unlocking direction, the tray 1 will be placed in the storage body 25.
It is fixed to . In Figure 4, key 6
When the key screw 11 is turned counterclockwise in the figure, the key screw 11 rotates in the same direction and comes into contact with the inner peripheral surface of the guide hole 32 of the housing body lock 3, thereby moving the housing body lock 3 and moving the housing body lock 3'. move it. Therefore, the tips of the storage body bolts 3, 3' protrude from the outer peripheral surface of the storage body 25, and are fitted into holes (not shown) in the storage body 25 to fix the tray 1 to the storage body 25. After that, the key 6 can be pulled out from the keyhole. Further, the tumbler 7 is deflected from the position where the notch 9 faces the protrusion 10 due to the applied rotational force.

As described above, the tray of the present invention is equipped with a customer lock consisting of a storage body bolt that engages and disengages from the storage body to unlock and lock it, and a tongue bolt that engages and disengages from the lid body to unlock and lock the lid. The customer lock is so arranged that, by the operation of one key screw operated with the key of the customer lock, the opening operation of the storage body bolt and the opening operation of the tongue bolt are obtained following the opening operation of the storage body bolt. In addition, since the lid body and the tongue bar are configured as an automatic lock, the lid can be opened only after unlocking the customer lock with a single key to the customer lock, reducing the risk of loss. There are fewer chances to do so, and even if you forget to close the lid when you put it away, it will be automatically locked, so you won't have to worry about forgetting to close it, and remote control self-service will eliminate concerns about management.
