Description

[Detailed description of the invention] The present invention relates to a locking mechanism for a valuables box, and more specifically, the present invention relates to a locking mechanism for a valuables box, and more specifically, when stored in a desk drawer, etc., it prevents someone else from easily opening it or taking the box out of the box. Concerning the latching mechanism of a valuables box.

The applicant has devised several valuables boxes of this type in the past.

(Jitsugan No. 52-118511. Jitsugan No. 52-12698
2, see Utility Model Application No. 53-20423).

However, as a result of the subsequent commercialization, it was found that there were still some points to be improved, and the present invention attempts to solve these points.

More specifically, in the case of Utility Application No. 53-20423, which is one of the above-mentioned inventions by the present applicant, when the lid is opened using the key, the lid is forcefully opened all at once by the action of the return spring. As a result, it was found that the operator was surprised, and that there were problems such as fingers getting caught between the side frames of the outer lid and the lid.

Therefore, in the operation of unlocking the lid using a key, it is sufficient to recognize that the lid is indeed unlocked, and furthermore,
It is desirable for crime prevention to not show this unlocking phenomenon on the outside, and it is not necessary for the lid to open automatically at that time. It is understood that it would be more preferable if the opening could be made only by the operation of .

In this way, requiring two steps to open the lid (unlocking with the key and unlatching the lid) can be said to be a desirable means of protecting the valuables box from others. .

Next, to limit the application of the present invention by way of example,
The present invention provides a valuables box of the type described in the specification of Utility Model Application No. 53-20423, in which the front part of the box body 1 has a drawer structure. That is, the feature is that the release of the lid is associated with the action of pulling out the box body 1 forward.

Hereinafter, the locking mechanism of the present invention will be exemplarily described with reference to the accompanying drawings.

FIG. 1 is an exemplary external side view of a valuables box to which the present invention is applied, which includes a box body 1, a box lid 2, and an outer lid 3. 4° 5 (see FIG. 3), which is pivotally supported via a bracket 7.7 on a rotation axis 6 which passes horizontally through the 4° 5 (see FIG. 3). 5, but any bracket (not shown) in any other position pivoted to the rotating shaft 6 may be used, as will be seen later in the description.
extend downward as shown in Fig. 1 7' (Fig. 2, 2
'In the figure, it is bent and extended with respect to the original bracket 7), and a contact rod 32 is provided at its outer end, pivotally connected by a pivot pin 31, and its free end, that is, the contact end. 33 indicates the valuables box 10 when the lid 2 is closed.
The length of the abutment rod is determined so that it abuts against the rear wall 34 of the drawer 30 (FIG. 1) or leaves a slight gap 35.

FIG. 1 shows other parts (see FIG. 2) to explain the normal relationship between the lid latching mechanism of the present invention, that is, the contact rod 32 interlocked with the lid, and the drawer 30 of the valuables box 10. ) is omitted, and when the drawer 30 is pushed into the valuables box main body 1 and the lid 2 is locked 9, the free end 33 of the contact rod 32 interlocked with the lid is substantially attached to the rear wall 34 of the drawer 30. It shows that it is in contact with the

In the figure, 3' indicates a sleeve portion that securely supports the outer cover 3 (actually, any suitable frame will do) for holding the valuables box 10 inside a desk or the like, and 3'' is a sleeve portion that securely supports the rotating shaft 6. This is the part that hangs onto the ceiling protrusion inside the desk.

In FIG. 1, many other parts are omitted in order to show the engagement relationship between the contact rod 32 and the drawer 30 of the valuables box, but in reality, various mechanisms are protected at the back of the box. Partition wall 26 for
Therefore, the tip of the contact rod 32 passes through the opening 36 provided in the partition wall 26 and presses against the rear wall 34 of the drawer 30.

Although the locking mechanism of the valuables box lid 2 according to the present invention is understood from the above, the structure and operation of the valuables box illustrated in the drawings will be briefly explained in connection therewith.

The outer lid 3 can be opened up to an angle of approximately 45° (Fig. 2, 3''), and its rotation axis 6 rotates the integrally formed sleeve 15 and arm 14.14 (Fig. 3). , is pivotally connected to the arm 14° 14, and is always kept in the box bottom 1 by a coil spring 19.
Due to the action of the ratchet mechanism 13 having the pawl 16 pressed against the fixed ratchet teeth 18 on the outer lid 3, the outer cover 3 cannot be closed by itself from the opening angle within the range in which the ratchet mechanism acts.

The condition of this outer cover is as shown in FIG.
There was no way to remove the valuables box from inside the desk because it was hanging on a protrusion 23 on the ceiling 22 inside.

In addition, the lid 2 of the valuables box body is attached to the brackets 7.7 on both sides.
' is rotatably mounted on the rotating shaft 6, and as previously illustrated, one bracket extends as 7' to pivot the abutment rod 32 between it and the drawer 30 of the valuables box. The ratchet mechanism 13 of the outer lid 3 is also operationally related to the ratchet mechanism 13 of the outer lid 3 as described below.

That is, the bracket 7 of the lid 2 has a cam portion 11 projecting downward in a substantially semicircular shape integrally with the lid, and the follower 12 having an angular cross section that is pushed and moved by this cam surface simultaneously pushes the outer lid 3 The follower or release lever 1 acts as a release device for the ratchet mechanism 13 of the
2 is supported by a pivot frame 20 fixed to the bottom of the box, and the other end 12' pushes up the lower surface of the claw 16, so that only when the lid 2 is opened at an angle (which can be designed arbitrarily) or more, the lid 2 is opened. The lid 3 can be closed again.

As stated in the previous application, this feature is significant in that it specializes the operation of taking out the valuables box from the desk.

Note that Fig. 3 25 shows a coil spring installed between the box body and the box body to constantly spring the lid 2 in the opening direction, but this spring 25 is not particularly important due to the nature of the valuables box. This (and may be omitted) will be understood in the following operational description.

Suppose that an authorized user who owns the key (or knows the unlock number) pulls out a desk drawer and unlocks the valuables box.

In conventional valuables boxes, just by simply opening the lid 2, the valuables inside the box could be taken out immediately.
It did not meet the purpose of trying to prevent even the slightest illegal act.

With the locking mechanism of the present invention, that is, the one in which the rear surface of the drawer 30 of the box is pressed by the contact rod 32 that is linked to the rotation of the lid 2, the lid 2 cannot be opened wide by itself just by removing the lock. Even if a small gap 35 is provided in relation to the unlocking structure of the lock, the lid 2 can be lifted only slightly.

If desired, by making at least the tip 33 of the contact rod 32 of an elastic material, the opening and closing operations of the lid can be made smooth and the lid 2 can be prevented from being lifted even when the lid is unlocked. .

It should be noted that a step 37 (FIG. 2') provided on the abutment rod 32 can be used to limit the opening of the cover 26, if desired, from harmful movement beyond the disabling limit of the ratchet mechanism 13. It is adapted to engage with the edge of the aperture 36.

After the lid 2 is unlocked with the key, by gradually pulling out the drawer 30 of the valuables box forward, the gap between the contact rod 32 and the rear wall 34 of the drawer 30 increases or becomes elastic. Away from the material, the lid 2 will therefore be opened by the force of the spring 25 (or manually if there is no spring 25).

That is, it is understood that the operation of opening the valuables box requires the first operation of using the key and the second operation of pulling out the drawer 30.

This increases the possibility of preventing illegal acts by third parties.

As explained above, the valuables box of this invention is a step forward in terms of crime prevention because even someone who has a duplicate key or knows the unlock number cannot open the lid simply by removing the lock. After that, the lid 2 can be opened by pulling the drawer 30 of the valuables box forward.

Also, if you want to take out the box from inside the desk, open the lid 2 to a certain degree (to the extent that the pawl 16 of the ratchet mechanism 13 lifts up), and then open the lid 2 to a certain degree (to the extent that the pawl 16 of the ratchet mechanism 13 lifts up). ) Since the top cover 3 can be removed from the ceiling protrusion 23 of the desk only by closing the top cover 3 and the cover 2 together, the valuables box main body can be taken out from the desk.

Therefore, after putting the valuables in the box, store them in the desk again (of course, you can put the valuables in and take them out in the drawer of the desk), and then press the outer cover 3 against the ceiling protrusion inside the desk. After that, (
Or, before putting the box in the desk), push in the drawer of the crystalline phase, close the lid 2, and remove the lock (with enough force to compress the elastic material if necessary) to open the valuables box. is completely stored.
