  The safety box applied to the valuables protection storage box, which is fixed inside the drawer of the hospital room as described above, protects valuables from theft by storing valuables and locking them with a key, After the valuables are stored, the release is locked with the key, but should not be opened with tools other than the key.

However, in the technique provided in Patent Document 1 (Japanese Patent Application Laid-Open No. 2002-155669), the guide rails of the main body box are bent outwardly at the upper ends of both side plates to form grooves. Since the fitting part formed by bending both sides of the slide cover inward is slidably fitted into the groove of the guide rail from the outside, the central upper surface plate connected to the both sides fitting part of the slide cover A fitting gap formed between the lower surface of the main body box and the upper surface of the cover portion on the center side connected to the guide rails on both sides of the main body box is opened to the rear of the safety box.
For this reason, in this prior art, it becomes possible to insert a plate-like body from the rear into the fitting gap opened to the rear, and the key lock is released by the insertion of the plate-like body. It cannot be said that there is no possibility of becoming.

In addition, since such a safety box is fixed inside a drawer, it is required to be configured as a highly rigid box-like body that is thin and light and has no deformation.
However, in the above prior art, the main body box is formed in a box shape by welding the corners of the flat plate, and the slide cover is also manufactured mainly by the fillet welding of the flat plate. Inevitable, the thickness must be increased to some extent in order to suppress the deformation.
For this reason, the safety box becomes thick, the weight increases, and the number of welding parts increases, so the number of processing steps increases.

  In view of the problems of the prior art, the present invention prevents accidental release of the key lock, improves safety, reduces the number of welding steps, reduces the number of processing steps, and is a thin, lightweight, and highly rigid box-shaped body. It aims at providing the safety box which consists of, and its manufacturing method.

  The present invention achieves such an object, and a key storage box is attached to the front side, and an opening for taking in and out stored items is opened on the upper surface, and guide rails extending in the front-rear direction are formed on both upper side portions. The box-shaped main body box and fitting portions that are fitted to the guide rails of the main body box are formed on both sides, and the opening of the main body box is opened and closed by reciprocating along the guide rails. In the safety box having a slide cover, the main body box is formed by bending the upper ends of both side plates inward to form the guide rail having a groove, and the slide cover is bent by bending both sides outward. A fitting portion is formed, and the fitting portion is slidably fitted in the groove portion of the guide rail, and further on the slide cover. A plate is slidably fitted inside a cover portion provided outside the main body box so that the opening of the main body box can be opened and closed, and a gap between the cover portion and the upper surface plate of the slide cover is formed. It is characterized by opening to the front side.

In this invention, preferably, the main body box is formed by bending the upper end portions of both side plates inward by bending to form the guide rails integrally with the side plates, and the lower space of the guide rails forms both sides of the storage chamber. Forming part.
In this invention, it is preferable that the slide cover bends both ends of the upper surface plate that opens and closes the opening to the outside so as to integrally form the fitting portion with the upper surface plate, and at the front end portion of the upper surface plate. Constructed by welding the handle.

And the invention of the manufacturing method of the safety box which consists of the above structure is characterized by the following (1) and (2).
(1) The main body box is formed by bending both sides of the bottom plate upward to form both side plates, and bending the upper end of each side plate inward to form a guide rail having a groove. A single plate is bent to form an integrally formed plate, and a front plate and a back plate are welded to the front end portion and the rear end portion of the integrally formed plate.
(2) The slide cover is formed by integrally bending the both ends of the upper surface plate that opens and closes the opening to the outside so that the fitting portion with the guide rail is integrally formed with the upper surface plate.

  According to this invention, the upper ends of both side plates of the main body box are bent inward to form a guide rail having a groove, and both sides of the slide cover are bent outward to form a fitting portion, A cover portion slidably fitted into the groove portion of the guide rail, and an upper surface plate of the slide cover is slidably fitted inside the cover portion of the main body box, and a cover portion provided outside the main body box; Since the gap with the upper surface plate of the slide cover is opened to the front side, the gap is not opened to the rear side of the safety box, and it becomes impossible to insert a plate-like body from the rear, and the safety is inserted into the gap. Safety can be prevented by preventing theft of the items stored in the safety box due to the key lock being removed by inserting a plate-like body from the back side of the box. To above.

In addition, the main body box is formed by bending a single plate of the bottom plate, both side plates and the guide rail into an integrally formed plate, and the front plate and the back plate are welded to the front end portion and the rear end portion of the integrally formed plate. In addition, the bottom plate and both side plates, which are strength members, and the guide rail can be formed of an integrated plate material without a welded portion, and the two plates of the front plate and the back plate having a small ratio as the strength member are welded to the end portions of the integrated plate material. Therefore, since the welded portion is a front plate and a rear plate that do not require large strength as a whole and the welded portion does not require great strength, a thin, lightweight, and highly rigid main body box can be obtained.
Moreover, since there are few welding parts as mentioned above, compared with the prior art like the said patent document 1, the processing man-hours including a welding man-hour can be reduced.

  In addition, the slide cover is bent at both ends of the upper surface plate that opens and closes the opening of the main body box, and the fitting portion with the guide rail is formed integrally with the upper surface plate. As a result, an integrated plate structure having no welded portion is obtained, a thin and lightweight slide cover is obtained, and handling properties such as a slide operation are good, and the number of processing steps can be greatly reduced as compared with the conventional technique.

Furthermore, the present invention is specifically configured as follows.
(1) The main body box forms a reinforcing portion having a box-shaped cross section by projecting inward a part of the lower side of the guide rail on both side plates.
(2) The main body box forms a box-shaped reinforcing part by an upper part of the back plate and a rear end part of the cover part.

  In addition, the main body box is composed of a single plate without bending the bottom plate, both side plates, and the guide rail welded portion, which is a strength member, because the plate, both side plates, and the guide rail are bent into a single plate. It is possible to weld the two plates of the front plate and the back plate, which have a small ratio as a strength member, to the end portion of the integrated plate material, so that there are few welded portions as a whole and the welded portion needs a high strength. Since the front plate and the back plate are not used, a thin, lightweight and highly rigid main body box can be obtained. Moreover, since there are few welding parts as mentioned above, compared with the prior art like the said patent document 1, the processing man-hours including a welding man-hour can be reduced.

  In addition, the slide cover is integrally formed with the upper surface plate by bending a single plate at the fitting portion with the guide rail, so that it has an integrated plate structure without a welded portion only by bending, and a thin and lightweight slide cover is obtained. Thus, handling properties such as a sliding operation are good, and the number of processing steps can be greatly reduced as compared with the conventional technique.
