Description

[Detailed Description of the Invention] The present invention particularly relates to a door suitable for use in a safe deposit box or the like having a large number of storage parts.

In general, safe deposit box doors are required to be able to open approximately 180 degrees relative to the safe deposit box body, and that the hinge shaft is not exposed to the outside. They were processed and formed to form a set of hinge shafts by themselves, and the door was assembled by fitting them together, which not only made the processing and forming of the safe deposit box body and door body complicated, but also made it difficult to assemble. It was time-consuming and had the disadvantage that the components were not interchangeable.

The present invention was developed in view of the above-mentioned circumstances, with the purpose of providing a door for a safe deposit box, etc., which has a simple structure of constituent members, is easy to assemble, and has high interchangeability of constituent members. And its composition is
A projecting portion having a shaft through hole is formed at the front end of the upper and lower horizontal partition plates constituting one storage section of a safe deposit box, and a hinge shaft penetrated through the shaft through hole of the projecting portion is made of appropriate material such as brass. A substantially cylindrical shaft part into which a metal sleeve is fitted and an opening with a width slightly larger than the diameter of the sleeve formed on the side surface, and a tongue plate-shaped door extending from the edge of the opening. The hinge shaft consisting of the body attachment part,
The sleeve is held in the shaft mounting part and fixed to the sleeve from behind with screws, etc., and a flat door body is positioned in the door mounting part so as to close the opening in the shaft mounting part, and the door body is positioned from behind. It is characterized by being fixed with screws or the like.

Next, embodiments of the present invention will be described with reference to the drawings.

The figure shows the case where the door of the present invention is applied to a safe deposit box that has multiple storage areas, where A is a horizontal partition plate, B is a horizontal partition plate,
is a door stop plate, and one storage part of the safe deposit box is composed of vertical walls of upper and lower horizontal partition plates A, A, and left and right door stop plates B, B.

Reference numeral 1 denotes a projecting portion provided at the end of the portion constituting one of the housing portions of the upper and lower horizontal partition plates A, A, 2 a shaft through hole bored in the projecting portion 1, and 3 a shaft through hole formed in the projecting portion 1. The hinge shaft 4 is inserted into the shaft through hole 2, and the sleeve 4 is fitted onto the hinge shaft 3. Brass or the like is used for the sleeve 4 to prevent biting during rotation and ensure smoothness. At the same time, a slight gap is formed between the sleeve 4 and the hinge shaft.

Reference numeral 5 denotes a hinge shaft in which a shaft mounting portion 8 having an arcuate cross section and an opening 7 having a width larger than the diameter of the sleeve 4 is formed at one end of a flat door mounting portion 6; It is fixed to the sleeve by a screw hole 9 and a push screw 10 provided in the part 8, and when the hinge body 5 is in the closed state, the shaft mounting part 8
A safety engagement groove 11 is formed along the longitudinal direction of the side end portion of the door stop plate B so as to engage with a safety engagement piece 12 of the door stop plate B which is projected to the side of the door stop portion.

Reference numeral 13 denotes a door body having a locking device 14, which is attached to the door body attachment part 6 of the hinge body 5 by means of an attachment hole 15 and a bolt 16 provided in the door body attachment part 6. In order to prevent the opening 7 from being exposed to the outside after the door body 13 is attached, a stepped portion 17 is formed near the opening 7 and the door body 13 is fitted therein. 17
This constitutes the door of the present invention.

The door of the present invention constructed as described above can be assembled in the main body of a safe deposit box or the like in the following manner.

That is, first, the sleeve 4 is arranged between the respective overhangs 1, 1 provided on the upper and lower horizontal partition plates A, A, and the hinge shaft 3 is inserted into the shaft through hole 2 of the sleeve 4 and the overhangs 1, 1. After inserting the hinge body 5 into the door attachment part 6
When the sleeve 4 is placed in the shaft mounting part 8 in such a state that the inner side is on the inside, and the set screw 10 is used to fix the sleeve 4 to the sleeve 4, there is a space between the sleeve 4 and the hinge shaft 3 as described above. Since a slight gap is formed between the hinge body 5 and the hinge shaft 3, the hinge body 5 is rotatably fixed to the hinge shaft 3.

Next, after fitting one end of the door body into the opening 7 of the hinge body 5, the door body is attached to the hinge body 5 using the bolt 16.
The assembling work is completed by attaching the sleeve 4 to the door attachment part 6 of the housing.For a large number of housing parts, the work of fitting the sleeve 4 onto the hinge shaft 3 is performed for all the housing parts. Later, a hinge body 5 and a door body 13 are attached to each storage section.
All you have to do is attach .

In the above embodiment, the hinge body 5 was formed so that the door attachment part 5 was located inside the hinge shaft 3, but the hinge body used in the door of the present invention is not limited to this structure, and the door attachment part 5
may be located on the outside with respect to the hinge shaft 3, and when manufacturing them, they may be manufactured individually to fit the housing part, but they may be manufactured using extrusion molding etc. to have the same cross-sectional length. It is more advantageous in terms of cost to manufacture the length member by forming it and cutting it according to the height of the accommodating portion.

In the door of the present invention assembled as described above, the hinge shaft 3 that controls its rotation is located outside the opening surface of the storage section, so the door body 13 can be opened approximately 180 degrees with respect to the main body. Therefore, when the inner box accommodated in the storage section is put in and taken out, there is no possibility that the inner box and the hinge will come into contact with each other and hinder smooth putting in and taking out.

On the other hand, safe deposit boxes, etc. that have doors with hinge shafts located outside the main body, such as the door of this invention, are susceptible to theft because the hinges can be easily cut with a hacksaw. However, if the safety engagement piece 12 is engaged with the safety engagement groove 11 in the closed state of the door as in the above embodiment, even if the hinge shaft part is cut off, There is no risk of the door being closed even if the door is closed, and this structure also prevents foreign objects from being inserted from the outside.

Therefore, when assembling the door of the present invention, it is not necessary to fit a set of hinges as in the case of assembling conventional products, and after fixing the hinge body to the sleeve fitted to the hinge shaft, the hinge body It is extremely simple as all that is required is to attach the door body to the door body, and together with the fact that the component parts can be manufactured by extrusion molding etc. and are highly compatible, it is possible to manufacture and provide safe deposit boxes etc. at low cost. .

In addition, since the manufacturing process can reduce the number of machining steps for the component parts, there are fewer scratches that are likely to occur in conventional machining steps, and not only can the finish be beautiful, but also the dimensional accuracy can be increased.

Since the present invention is as described above, it is particularly practical as a door for a safe deposit box.
