ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a row of switchgear cabinets arranged next to each other, wherein vertical frame legs of adjoining switchgear cabinets are connected with each other and bottoms and tops of the racks are closed by bottom and top cover plates, and wherein the bottom and top cover plates have bevels on at least facing sides and bevels are set back with respect to outsides of the adjoining vertical frame legs and form a gutter with end sections of the bevels and/or profiled sides of facing horizontal frame legs.
2. Description of Prior Art
Conventional switchgear cabinets are individually placed, wherein bevels of a cover plate form a rain gutter which receives rainwater running off the cover plate and lets it drip down at a front and/or a back of the switchgear cabinet. The bevels are advantageous with individually placed switchgear cabinets, but with a row of switchgear cabinets arranged next to each other they do not block joint areas between the adjoining switchgear cabinets, so that water collects and can penetrate into interiors of the switchgear cabinets.
SUMMARY OF THE INVENTION
It is one object of this invention to definitely and simply close joint areas between adjoining switchgear cabinets in connection with a row of switchgear cabinets of a type as previously mentioned, without having to give up the advantage of satisfactory water removal by means of the bevels of the bottom and/or top plate when placing the switchgear cabinet as a single cabinet.
In accordance with this invention, this object is attained with gutters in an area of bottom and/or top plates of adjoining switchgear cabinets which are closed flush with the bottom and/or top plates from the front of the switchgear cabinets toward the rear with respective cover strips.
The bottom and/or the top are closed in flush planes using the cover strips, so that the joint areas are clearly sealed. If water enters between the cover strips and the bottom and/or top plate, the water is conducted out of the area of the joints by the bevels of the top and bottom plates and the profiled sides of the frame legs and is diverted at the front and/or back of the switchgear cabinets.
For a simple application of the cover strips, in one embodiment facing end sections of the bevels of bottom and/or top plates of adjoining switchgear cabinets are at a distance from each other and with a web formed on them, the cover strips extend between the end sections and behind them.
Then the assembly can be performed in such a way that the cover strips are snapped into the gutters between the bottom and/or top plates of adjoining switchgear cabinets, transversely with respect to a longitudinal section, or the cover strips are pushed in a longitudinal direction into the gutters between the bottom and/or top plates of adjoining switchgear cabinets.
In accordance with one embodiment of this invention, a good support of the cover strips in the gutters of adjoining bottom and/or top plates is achieved because the end sections form an acute angle with respect to the leading sections, and the webs of the cover strips are designed as dovetailed webs with an appropriate inclination.
If the cover strips are formed as sections of a strand of a plastic material, they can be produced simply and cost-effectively by a plastic extrusion process. For reducing production costs it is also possible to design the cover strips as sections of a strand of plastic material.
In accordance with a further embodiment, ends of the hollow cover strips can be closed with cover plates, which are introduced with plug connectors formed on them into hollow spaces of the hollow cover strips, and are there held by a snug fit and/or a press fit.
