Abstract

PURPOSE: To advance the security of a safe by making the door freely swing in an openable and closable manner as the door is moved slightly toward the direction of a hinge. CONSTITUTION: The casing 1 buried in a wall 2 has a front frame 3 for an access opening 4, and the access opening is protected by a door 6 being inclined or rotated about a horizontal shaft 7. The hinge 8 includes a guide 9 such as a hole or the like for accepting a rod 10 attached to the inner surface of the door 6, and the door 6 is rendered movable between two positions at both ultimate ends with respect to the plane of the door itself being in a parallel positional relation with the hinge 8. This results in that at one movement end, the door 6 is joined to the rear of the frame 3 of the access opening 4 so that the door never open. The movement of the door is carried out by a crank mechanism having an operation wheel 12 at its outside end.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION Although the present invention is specifically designed for safes, it is equally applicable to other applications where a door or other closure member is designed to close the opening. A safe with a closure device.

[0002]

2. Description of the Related Art A safe is a fixed device, for example built into a wall, or the weight of it makes the thief immobile or difficult to move. As is well known, in any case, the inside of the casing can be accessed by the basic structure of the safe including the casing and the access opening provided in the casing.

The opening provided in the casing can be closed by a door. Doors are usually designed to open outwards in order not to reduce the capacity of the safe. The dimensions of the casing are determined by the internal volume of the safe. Both the casing and the door are of sufficient strength to provide the required safety.
Usually, safe doors are connected to the safe casing by a hinge device consisting of a hinge or a set of hinges. This hinge device may be provided at the upper or lower end of the door, but is generally adapted to connect one of the side edges of the door to an adjacent portion around the opening.

The operation of closing the door to bring it into the locked state is generally performed by a bolt device operated by a lock mechanism, and the bolt device is composed of one bolt or a set of bolts. Various things are known not only about the structure of the locking mechanism itself but also about both the number and structure of bolts. For example, in the closed and locked condition, a mechanism in which a set of bolts is inserted into a socket provided around the perimeter of the access opening is well known. To open the safe, the locking mechanism pulls the bolt back into the door.

[0005]

Conventional safes are either complex and / or lacking in security. On the other hand, safes having a relatively simple lock mechanism can be pushed open in most cases by breaking a member such as a hinge that attaches the door to the casing. This weakness is most pronounced when the door is normally flush with the perimeter of the access opening.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a security lock that overcomes these drawbacks. The security lock according to the present invention is
Based on a completely new functional design, it has the dual advantages of simple structure and high safety. According to these objects, the invention provides a safe having a casing, an access opening provided in the casing, a door, and a support device for movably supporting the door. The access opening has a peripheral portion having a first width. The door can close the access opening and has a width greater than the first width. The support device has a member for tilting the door to open and close the access opening, and a member for moving the door to engage behind the periphery of the access opening.

In one embodiment, the door is mounted on the hinge and is movable laterally relative to the hinge in the plane defined by the door itself.
In this moving direction, the door is dimensioned to be slightly larger than the access opening. Thus, when the door is closed, it occupies the plane just inside the safe entrance. Thus, as the door moves slightly towards the hinge, the door is free to swivel to open and close. On the other hand, when closed and moved in the opposite direction, the entire door end opposite the hinge engages behind a corresponding portion of the perimeter of the access opening, thus preventing the door from opening. Therefore, in a sense, the door itself acts as a very large and strong bolt.

In order to move the door in the plane of the door itself, which lies in the plane in which the closing movement takes place, in addition to a guide allowing the movement of the door, there is a crank or cam between the hinge and the door. It is provided. Properly driven from the outside with the help of any suitable closure mechanism,
The crank or cam allows movement between the door and the hinge in one or the other direction. As a result, the door is locked or unlocked with respect to the access opening. Although movement in the door plane allows for a simple drive mechanism and is preferred, the invention is not limited to movement in the door plane. One component of door movement may be in a direction that is not in the door plane. For example, the door may be adapted to move both forward and sideways when the door is in the locked condition. The outline of the present invention described above,
A detailed description of embodiments below will be better understood with reference to the accompanying drawings. To illustrate the invention, a preferred embodiment is shown in the drawings. But,
It should be noted that the invention is not limited to the particular arrangements and devices described herein.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings. As can be seen by referring to FIGS. 1 and 2,
The safety closure device according to the invention is used for safes with a body or casing 1. The casing 1 is embedded in the wall 2 in the present embodiment, but may be an independent member placed freely. Casing 1
Has a front frame 3. The frame 3 forms an access opening 4 to the interior 5 of the safe. The access opening 4 is protected by a corresponding door 6. The door 6 has a horizontal shaft 7 in the embodiment shown in FIG.
It tilts or pivots about a vertical axis and in the embodiment of FIG. 2 tilts or pivots about a vertical axis 7 '.

In both embodiments, the hinge portion 8 has a shaft 7
It is rotatably mounted on (7 ').
The hinge portion 8 is a rod 10 attached to the inner surface of the door 6.
The door 6 has a guide 9 such as a hole for receiving
The plane of the door itself, which is in a positional relationship parallel to the hinge portion 8, can be moved between two extreme positions. At one of the moving ends represented by a broken line in the drawing, the door 6 can be freely tilted to open the safe, and at the other moving end represented by a solid line,
The door 6 is locked behind the frame 3 of the access opening 4 to prevent the door 6 from opening. The movement of the door 6 is performed by a crank mechanism. This crank mechanism has a crank 11 that penetrates through the door 6 and is rotatable with respect to the door 6. The crank 11 has an operating wheel 12 at the outer end thereof. On the other hand, crank 1
A crank arm 13 is formed at the inner end portion of 1. A journal 14 is provided at the end of the crank arm 13. The journal 14 is received in a bearing 15 forming part of the hinge portion 8. Therefore,
When the wheel 12 is rotated in one direction or the other, the door 6 moves in one direction or the other direction with respect to the shaft 7 (7 ').

The illustrated door drive mechanism is merely a preferred example of the solution. In either case, the door drive mechanism is assisted by a conventional type closing or locking mechanism. In the closed state, represented by the solid line in the drawing, the door 6 is in contact with the frame 3 at two or three of its ends. Therefore, this structure provides maximum safety. This is because the door 6 is inclined outward so that the safe cannot be opened. On the other hand, pushing the door 6 inwards (which does not make sense anyway because it does not open it) can be avoided by using a suitable internal buttress.

As can be seen from the embodiment of FIG. 2, the shaft 7'is arranged very close to the end of the access opening 4. On the other hand, the shaft 7 in FIG. 1 is provided at the relatively center.
This difference is due to the different directions of the respective axes 7, 7 '. In particular, since the shaft 7'is vertical, the weight of the door 6 does not influence the opening operation of the door 6. On the other hand, since the inclined shaft 7 is provided horizontally, the door 6 suddenly opens due to its weight. Thus, if the shaft 7 is horizontal, by locating the shaft relatively centrally,
It is preferred that the lower part of the door together with the drive mechanism of the door form a kind of counterweight to balance and slow the movement of the door 6. The present invention can be implemented in other forms without departing from the spirit or essence of the invention. Therefore, for the scope of the invention, reference should be made to the appended claims, rather than to the embodiments described above.
