Description

[Detailed description of the invention] The present invention relates to a valuables box, and more specifically, the invention involves rehanging a locked box inside a desk drawer, etc., and unlocking the box in order to take out the box. Regarding the small box that was made like this.

Lockable boxes for storing small valuables are well known.

Such a small box or valuables box is generally just one
It is only locked by an individual lock, so even if you don't have the key to open the lock? Even an unscrupulous person could easily take the whole box with him, and simply locking the box does not really prevent theft.

Therefore, in such a case, it becomes necessary to store the valuables box itself in a safe or the like.

Although the present invention is not as important as storing it in a safe, it is possible to simply store valuables in a desk drawer or the like. At the same time as hanging by the pre-provided protrusion,
To provide a structure of a valuables box that allows an authorized person (person with a key) to easily release the locked state between the box and the inside of a desk drawer.

Hereinafter, an embodiment of the valuables box of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is an external side view of a valuables box 10 according to the present invention, which includes a rain main body 1, a box lid 2, and an outer lid 3.
are the opposite side walls 4 and 5 of the box body 1 (see the plan view in Fig. 3).
The outer lid 3 is rotatably supported via a bracket 7.7 with respect to a rotating shaft 6 that passes horizontally through the rotating shaft 60. Fixed in state.

Referring to the plan view of FIG. 3, reference numerals 8, 8 are coupling pieces that non-rotatably engage with the rotating shaft 6, for example, through square holes, and are riveted to the shaft portion 3' of the outer lid 3.

Reference numeral 9 in FIG. 1 indicates a lock for closing the lid 2 on the screen 1.

FIG. 2 is a side sectional view showing the inside of the valuables box 10 shown in FIG. 1, particularly the relationship between the lid 2 and the rotating shaft 6. The ears 11 are rotatably supported by the brackets and horizontally protrude from some of these brackets. 1
2' to relax the shaft tightening action of the tightening spring 12.

FIG. 3 is a plan view taken along the line M-■ in FIG.
is a projecting piece attached to the rear end wall 14 of the box body 1 by welding, riveting, etc., and is used to securely hold one end 12 of the shaft tightening spring 12 that is tightly wound around the shaft 6. It is.

Therefore, in the winding direction of the tightening spring 12 shown in FIG. 3, when the other end 12' of the spring is in a free state as shown in FIG. It will be seen that although the shaft 6 can be rotated clockwise in the direction of FIG. 2, it is almost impossible to rotate in the counterclockwise direction due to the strong tight fit of the clamping spring 12.

Therefore, it is understood that similar restrictions are applied to the movement of the outer cover 3, which is fixed to both ends of the shaft 60, with respect to the shaft 6.

Although the coil spring 15, which is schematically shown only in FIG. The other end 15' is a so-called return spring for the lid 2 that applies a force to push up the lid 2 from below.This spring 15 is not an essential element for the valuables box 10 of the present invention. Although it is not, it is a desirable element.

The brackets 16 16 protruding from the inside of the end wall 14 of the box body represent bearings that rotatably support the rotating shaft 6, but in this case, they merely reinforce the bearing action of the side walls 4 and 5 of the box body. Therefore, it can be omitted if it is not necessary.

Alternatively, it may be a bearing (not shown) that stands upright from the bottom of the box.

Since the valuables box 10 of the present invention is constructed as described above, it can operate as follows when used.

For convenience of explanation, it is assumed that the valuables box 10 of the present invention is in the state shown in FIG. 1, that is, in a locked state with valuables inside.

It is assumed that this is placed in a desk drawer (Fig. 4) 20 and placed in a desk 21.

A lintel-like protrusion 23 is installed in advance on the ceiling 22 of the desk at an appropriate position (the position where the outer lid 3 of this valuables box hangs as shown in Fig. 4).
(It may match the front of the desk), so
Push up the outer cover 3 with your fingertips and remove the protrusion 2 inside the desk as shown in Figure 4.
3. Bring the tip 2' into contact with the ceiling 22' further back than 3.

In this case, since the rotating shaft 6 integrally connected to the outer cover 3 rotates clockwise as shown in FIG.
is subjected to a frictional force in the direction of relaxation, that is, in the direction of increasing the inner diameter, so that no interference occurs that prevents rotation of the rotating shaft 60.

In this state, even when the drawer 20 is pushed in, you will find that the valuables box was locked in the old days, and you cannot even take it out from inside the desk.

Next, an explanation will be given of the operation when the person who has the key takes out this valuables box from the desk.

If the drawer 20 of the desk is pulled out in the position O shown in FIG. 4, the situation will be almost the same as when a valuables box is placed in the drawer and the outer cover 3 is pushed up.

When facing this position and opening the lock 9 with the key in hand, the lid 2 can be raised to the position 2 shown in FIG. 4 by means of the return spring 15 or by the tip of a finger.

In other words, this position is a position where the protruding ear 11 shown in FIG. In other words, the inner diameter is larger than the outer diameter of the shaft.

Therefore, it will be understood that in the state shown in FIG. 4, or in a state in which the lid 2 is further raised, the outer lid 3 can also be freely lowered.

After that, if the outer lid 3 is sufficiently lowered (the lid 2 may be in a state where the tightening spring 12 is released again and the shaft 6 is tightened), and the desk drawer 20 is fully pulled out, valuables can be removed. Since the product box can be taken out from the drawer, the contents can be taken out and replaced later.

The subsequent operation is simply to lock the valuables box and reverse the removal operation as described above, so the details will be omitted.

In Fig. 4, since it is necessary to put your hand inside the desk drawer with a valuables box inside it, the outer cover 3 is in the position where the drawer is pulled out by a length D, which is enough to cover the drawer. Although the state in which the IE is hung on the protruding piece 23 is shown, as a modification of the assembly structure related to the present invention, for example, a small If a sliding door or the like is configured, the lock of the valuables box can be opened and closed and the outer cover can be raised and lowered even when the drawer is completely pushed in.

Although not shown, it is possible to appropriately extend the box body 1 to the rear of the rotating shaft 6 (to the right of the button in Fig. 1), or to press the outer lid 3 in a plan view to form an approximately inverted U-shape. It is possible to make modifications such as forming a
