DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a device for attaching a front frame to an open front of a housing having wall elements, wherein the wall elements in an area of the front have two wall sections placed vertically with respect to each other, one of which supports an open L-shaped strip.
2. Description of Prior Art
A conventional device is known from Great Britain Patent Reference 1 489 278. In this case one wall element has a plug connection, into which a plate can be inserted. The other wall element has two legs, which are spaced apart and parallel with respect to each other and have detent protrusions facing each other. Frame profiles of the front frame can be clipped into these detent protrusions. In this case the frame profile is held between the legs. A groove is between the frame profile and the leg on the front facing the viewer, which is distracting.
With known housings of this type, the front frames are bolted together with the front ends of the wall elements. This results in a considerable outlay of parts and assembly efforts and, in addition, the connection points are visible on the viewed side of the front frame.
SUMMARY OF THE INVENTION
It is one object of this invention to provide a device of the type mentioned at the outset, in which it is possible to quickly close off the open front of the housing with a front frame, wherein the connection points are not visible on the viewed side of the front frame.
This object is attained in accordance with this invention in that wall elements in the area of the front have two wall sections placed vertically with respect to each other, and a receiving groove inclined at 45.degree. is formed in one wall section, while the other wall section has an open L-shaped strip facing away from the receiving groove. Frame legs of the front frame are suspended by a round seating strip in the L-shaped strips of the wall elements and are aligned with the receiving grooves of the wall elements by being pivoted in complementary shaped receiving grooves. Securing elements are inserted into the closed receptacles of the two receiving grooves of the wall element and the frame leg, which fix the frame legs on the wall elements, and corner pieces are bolted together with the frame legs, which have penetrating screw receptacles and are connected with the wall elements, and complete the front frame.
The frame legs of the front frame are suspended with their seating strips in the L-shaped strips of the wall elements, pivoted and secured on the wall elements of the housing by the securing elements. The corners are filled with the corner pieces, which are bolted together with the adjoining frame legs. In this case the fastening screws are aligned in the plane of the front, and therefore the viewed side of the front frame forms a closed surface.
In accordance with one embodiment, the distribution of the receiving grooves, the seating strip and the L-shaped strip can be such that the semicircular receiving groove of the wall element is formed in the wall section located in an area of the exterior of the wall element and is open in the direction toward the rear of the housing. The L-shaped strip is formed on the wall section of the wall element which is parallel with the front and is open toward the opening of the front panel.
However, the distribution can also have the semicircular receiving groove and the L-shaped strip interchanged and applied to the wall sections, wherein the L-shaped strip is open in the direction toward the rear of the housing and the receiving groove is open toward the opening of the front. In this case the two embodiments differ in the direction of pivoting of the frame legs for producing the assembly position.
In one preferred embodiment, in the front frame the frame legs are embodied as hollow profiled sections with two parallel walls, wherein one wall with the seating strip or the receiving groove at least partially covers the wall section which is parallel with the front, and wherein the other wall extends
