A CLOSED SYSTEM FOR PLACING INSTALLATIONS, ESPECIALLY ELECTRICAL ONES

Abstract

A closed system for placing installations, especially electrical ones

The closed system for placing installations is formed by interconnected chamber modules (1, 2, 3, 4, 5) of a rectangular top view. In the connection area, the adjacent modules (1,2,3,4,5) are provided with lowered edges which overlap, and in the overlap area vertical through holes (9) are provided for module (1,2,3,4,5) fasteners. The fasteners consist of screws (11) and nuts (12). The lowered edges are provided in the horizontal abutting surfaces with horizontal coaxial passages (10). These passages (10) connect the chambers (6) of adjacent modules (1,2,3,4,5) and cables pass through them. The passages (10) are provided with a sealing grommet (13) which is made of a resilient material. The chamber modules (1,2,3,4,5) consist of two caps (7, 8) attached to each other.

EXAMPLES OF INVENTION EMBODIMENT

[0018] The closed system for placing electrical installations is, according to FIG. 1, formed by interconnected three chamber S-modules 1 and two end modules 5. According to FIG. 2, the closed system consists of one chamber X-module 4, four chamber S-modules 1, two chamber T-modules 3 a two chamber A-modules 2. All modules 1, 2, 3, 4, 5 are formed by two adjacent caps 7, 8 and feature a rectangular shape in top view. This shape may be polygonal or even circular within the scope of the invention. In the connection area, adjacent modules 1, 2, 3, 4, 5 are provided with lowered edges that overlap. The connection areas thus provided have S-modules 1 a A-modules 2 on two opposite sides, T-modules 3 on three sides, X-modules 4 on all four sides and the end module 5 on only one side. The modules contain their own electrical installation, as well as lighting elements, measuring instruments, computer equipment, etc. according to the required use.

[0019] As apparent from FIGS. 3 and 4, vertical through holes 9 are formed in the overlap area for fasteners, which are screws 11 and nuts 12. They are used to connect the adjacent modules 1, 2, 3, 4, 5 together, as well as the caps 7, 8.

[0020] In the horizontal abutting areas of the overlap, passages 10 are formed between the chambers 6 of adjacent modules and cables pass through these passages 10—as shown in FIGS. 3 and 5. The passages 10 connecting the chambers 6 of the adjacent modules 1, 2, 3, 4, 5 are provided with a sealing grommet 13, which also protects the cables from damage due to sharp edges of the passages 10. A different grommet may also be used within this invention, e.g. standard threaded grommet.

[0021] FIGS. 4 and 5 show unmarked seals between the caps 7 and 8. These seals may also be formed by other known methods within the scope of the invention.

[0022] Modules 1, 2, 3, 4, 5 are designed as castings of metal alloys, or they may be made of plastics alternatively.

INDUSTRIAL APPLICATION

[0023] The closed system for placing the installation according to the invention is particularly intended for electrical installations. It is mainly useful in the environments requiring high security, for the lighting of internal and external industrial operations, storages, wells, docks, airports or as public lighting, both outdoors and in buildings. The closed system according to the invention is also resistant to various weather conditions.
