Abstract

PURPOSE:To increase safety in cover mounting and removing operations and to maintain a stable fixation of the cover, by establishing a pair of setting and supporting members, which are combined so as to slide each other, at the corresponding of an inner face of a case and a back face of the cover and by establishing a stopper. CONSTITUTION:An electric parts container is made of a cover 3, a pair of setting member 10 and supporting member 11 and a stopper. The cover 3 is mountable and removable from outside and covers an opening portion 2a of a case 2 which is buried in a wall 1 and can contain an electric part 6. The setting member 10 and the supporting member 11 are established at the corresponding portions of a back face 3a of the cover 3 and an inner face 2b of the case 2 in such a combining state as to slide each other. The stopper can limit a sliding range of the setting and supporting members and can also cancel the combination of them. Therefore, the cover does not fall immediately after the removal of screws 4 as conventional, because the cover is supported by a combination of the setting member 10 and the supporting member 11.

[Problem to be solved by the invention] In the conventional elevator electrical component storage box as described above,
A cover (3) was removably attached to the opening (2a) of the case (2).

In recent years, due to the diversification of designs, a large number of thick covers (3) or covers (3) with large external shapes have been adopted as the cover (3).

Increasing the thickness and increasing the size of the cover (3) results in an increase in the weight of the cover (3) itself.

Therefore, in the conventional structure for attaching and detaching the cover (3),
Problems such as safety during attachment/detachment work or an inability to maintain a reliable and stable fixed state have started to occur.

That is, in the screw attachment/detachment structure shown in Fig. 6,
When the screws (4) are removed, the heavy cover (3) immediately falls off, making attachment and removal work extremely dangerous. In addition, in the case of the cover (3) with the plug-in detachable structure shown in Fig. 8, the insertion plate (7) is easily fixed in the center and easily falls off due to the weight of the cover (3). It became. For this reason, there has been a demand for an elevator electrical parts storage box with a removable structure that can cope with the increase in the weight of the cover (3).

Therefore, this invention makes it possible to safely attach and detach the cover even when the weight of the cover itself increases due to an increase in the thickness of the cover or an increase in its external size. It is an object of the present invention to provide an electrical parts storage box for an elevator that can maintain a certain stable fixed state.

[Means for Solving the Problems] An electrical component storage box according to the present invention has an opening (2a) of a case (2) embedded in a wall (1) and capable of storing an electrical component (6) from the outside. a removable cover (3);
