DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
This invention is related generally to storage cabinets and, more particularly, to storage cabinets for electronic components.
BACKGROUND OF THE INVENTION
In switch cabinets like the ones used for electronic components, the mounting plates, module supports or the like are rigidly built into the rack. During earthquakes, these rigid connections lead to damage and destruction as a result of the shearing and pulling forces that arises in varying directions and that can lead to total operating failure.
It is desirable to store components, especially sensitive electronic components in a cabinet that could protect them from the shock and vibration that results from events such as earthquakes.
OBJECTS OF THE INVENTION
It is an object of this invention to provide overcoming some of the problems and shortcomings of devices of the prior art.
Another object of this invention is to provide a switch cabinet that provides earthquake proof protection for components stored within. How these and other important objects are accomplished will be apparent from the following descriptions and the drawings.
SUMMARY OF THE INVENTION
This task is accomplished, according to the invention, by having at least one insertable housing or insertable rack, that is, fastened in a cushioned manner on horizontal carrier rails which are inserted between the lateral vertical rack members, and by having the upper area of the insertable housing or insertable rack connected to the vertical rack members of the rack by means of horizontally directed cushioning buffers, either directly or by means of angle fasteners.
The invention concerns an apparatus for containing sensitive components such as electronic equipment comprised of: (1) a switch cabinet having a plurality of walls and at least one cabinet door; (2) a support rack having a plurality of lateral vertical rack members enclosed within the switch cabinet; (3) at least one housing having upper and lower portions, inserted in the support rack and connected in the upper area to the vertical rack members; (4) a plurality of horizontal carrier rails inserted between the lateral vertical rack members and fastened to the lower portion of the housing; and (5) at least one cushioning device having a first and second end, affixed between the housing and the horizontal carrier rails.
The shearing and pulling forces acting on the switch cabinet are kept away from the insertable housing or insertable rack means of this cushioned type of insertion, since the vertical and horizontally directed cushioning buffers permit a limited deflection and thus movement of the insertable housing or insertable rack on all sides with respect to the rack, and thus with respect to the actual switch cabinet. The inserted components lodged in the insertable housing or insertable rack are therefore protected with regard to forces arising from an earthquake.
In a specific embodiment of the invention, the housing has an underside with four corners. A cushioning device is arranged in each of the four corners and the cushioning devices connect the underside of the housing to the horizontal carrier rails. In a particular aspect of this embodiment, the housing has a first and second side. The first and second sides each have upper and lower areas, and vertical cushioning devices positioned perpendicular to the first and second sides connect the vertical rack members to the upper areas of the first and second sides. In a specific aspect of the embodiment, the cushioning device has a cylindrical shape with a first and second end and threaded bushings are inserted into each end.
In yet another aspect of the embodiment, the housing has a first side that has an opening in its center. A second side is positioned opposite the first side and a third and fourth side are located perpendicular to the first and second sides and opposite of each other. In such embodiment, a first and second end portion, opposite of each other, are attached to the first, second, third, and fourth sides of the housing.
