Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a safe for fire protection and theft prevention, and a hidden hinge type safe in which a hinge for opening and closing a door cannot be seen from the front.

(Prior art) In recent years, in order to unify the design of indoor equipment such as cabinets and interior equipment such as cabinets, the front surface is flattened to eliminate the unevenness between equipment and the hinge of the door. The one hidden from the front is offered, and even for fireproof and anti-theft safes, a hidden hinge type unified with other cabinets has been proposed.

As shown in FIG. 5, this conventional hidden hinge type safe has a door 2 having a convex portion 2a that fits in the front opening of the storage main body 1.
A flange-shaped projecting portion 2b is integrally provided at the peripheral portion of the storage container body 1, and the projecting portion 2b covers the peripheral surface 1b of the storage main body 1. Then, the pivotal fitting 3a forming one of the hinges is projected from the front surface 1a of the peripheral edge portion of the storage main body 1 and inserted into the hole 4 formed in the rear surface of the overhanging portion 2b of the door 2 and provided in the hole. The hinge 3b, which constitutes the other of the hinges, is pivotally attached by the pivot 3c. In addition, pivot 3c
Is fixed to one of the pivot fittings 3a or 3b in advance, the pivot fitting 3a is inserted into the hole 4, and the door 2 is attached by aligning the pivot fitting 3c and dropping it. ing.

(Problems to be solved by the invention) As described above, in the conventional hidden hinge type safe, the needle protruding portion of the door is used.
The door 2 can be rotated only within a range of about 90 ° in which the edge of the hole 4 formed on the back surface of 2b does not contact the pivot fitting 3a on the main body side.
When it is inconvenient to take in and out of the contents, and when it is necessary to carry it manually, the door is often removed and carried, but at that time, the convex portion 2a on the back of the door is removed from the opening of the storage main body 1. It is necessary to attach and detach the door at the angle immediately after
Moreover, since the pivot 3c cannot be seen at this angle, there is a problem in that the work needs to be roughly done and the work is difficult.

In consideration of such conventional problems, the present invention has a door with a
The purpose of the present invention is to provide a hidden hinge type safe that can be opened by 0 ° and can be easily attached and detached during transportation.

(Means for Achieving the Object) A feature of the hidden hinge type safe of the present invention for achieving the above-mentioned object is that it comprises a storage cabinet body and a door for opening and closing the opening of the storage cabinet body. One pivotal fitting of the hinge is projected on the front surface of the side edge of the main body, and the other pivotal fitting of the hinge is projected on the side surface of the door so that both pivotal fittings can be pivoted with respect to each other. A box-shaped hinge cover having a notch in the pivot fitting metal part projecting on the storage body is connected to the side surface of the door which projects the pivoting metal fitting, and a side edge front surface of the storage body is provided. It is arranged and fixed in the recess formed by the side surface of the door.

(Function) In this hidden hinge type safe, the door is opened and closed centering on the pivot, and the hinge cover is operated together with the door when the door is opened and closed, but the pivot fitting is fixed to the storage cabinet side in the notch. Will operate relative to each other, and the door can be opened and closed within a range of approximately 180 ° depending on the length of the notch.
Also, by removing the hinge cover, the hinge consisting of the pivotal fitting and the pivot is exposed, and from the angle at which the back surface of the door is removed from the main body of the storage cabinet
° The door can be attached and detached while viewing the hinge part in the open angle range.

(Embodiment) Next, an embodiment of the present invention will be described with reference to Figs.

In the figure, 10 is a storage main body, 11 is a door, both of which are covered with steel plates on the inner and outer surfaces, and heat-resistant heat insulating material is filled in the thickness, and the whole has a fire resistant structure. ing. A convex portion 11a that is inserted into the opening of the storage case body 10 is integrally provided on the back surface of the door 11, and a plurality of locking rods 12 project from the upper, lower, left, and right peripheral surfaces of the convex portion 11a, and the storage case body 10 The lock bar is fitted into the lock bar fitting hole 13 on the inner surface of the opening so that the hinge does not come off even if the hinge is broken (shown in FIG. 2).

Flange-shaped protrusions 11 are provided on the upper, lower, left, and right peripheral surfaces of the door 11.
b is formed, and the other three-sided edges except the vertical side are
The storage main body 10 is formed in a size that covers the front surface of the peripheral edge of the opening. A pair of pivot metal fittings 15 are vertically arranged on the side surface 14 of the overhanging side vertical edge of the overhanging portion 10b. The both ends of the pivot fitting 15 are integrally formed with a vertically oriented bearing tubular portion 15a.

On the other hand, on the front surface 16 of the door pivot side edge of the storage main body 10, a pivot fitting 17 is provided at a position corresponding to the lower side of both pivot fittings 15 of the door 11. The pivot fitting 17 has a rectangular shape, and a pivot 18 is vertically provided on the upper surface of the pivot fitting 17. This axis 18
The door 11 can be mounted so as to be openable and closable by dropping the bearing cylinder portion 15a of the pivotal fitting 15 on the door side and fitting it.

Further, the side surface 14 of the pivot side edge of the door 11 is arranged in a recess formed by the side edge front surface of the storage case main body 10 and the side surface 14 of the storage case main body 10, and the door pivot side side edge of the storage case main body 10 is disposed. A hinge cover 19 covering the front surface 16 of the is screwed. The hinge cover 19 is formed in a box shape having a substantially C-shaped channel in cross section, and is screwed so that the open side surface of the C shape faces the back side. Furthermore,
The hinge cover 19 is formed with a notch 20 from the side to the front at a position corresponding to both pivot fittings 17 on the storage body side. By opening the door 11, the inside of the notch 20 is pivotally fitted.
17 is moved relative.

In the drawing, 21 is an end cover of the hinge cover, 22 is a mounting screw, 23 is a tool insertion hole, and 24 is a hole cap.

When the door 11 of the safe configured as described above starts to open from the closed state, the hinge cover 19 is rotated around the pivot 18 together with this, and the notch is formed in the attachment base of the pivot fitting 17 on the storage body 10 side. The front edge of 20 is opened to approximately 180 ° where it comes into contact. Also, the door 11 can be attached / detached by opening the hinge cover 19 at an angle of 180 ° or more, and the protrusion 11a on the back of the door is rotated until it completely comes out of the opening of the storage main body 10. By lifting the door 11 upward, the bearing cylinder portion 15a of the pivot fitting 15 is detached from the hinge pivot shaft 18 and is detached from the storage case body 10.

(Effect of the device) As described above, in the hidden hinge type safe of the present invention, the hinge cover is detachably attached to the side face of the pivot side of the door, the notch is provided in the hinge cover, and the pivot fitting of the storage body side is attached to the hinge cover. By enabling relative movement in the notch, the door can be opened and closed with respect to the storage main body from the closed state to a range close to about 180 °, and moreover, the entire front surface of the storage main body is Further, the door can be attached / detached by removing the hinge cover while visually checking the hinge in a wide opening angle range.
