DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a connecting arrangement for connecting a control apparatus with a control panel.
BACKGROUND OF THE INVENTION
Solutions are known whereby the control apparatus and the control panel form a structural unit and therefore can only be utilized when together. Since the connecting arrangements are formed as one piece with the parts of the control apparatus and/or of the control panel, the upper side of the control panel always assumes the same angular setting with regard to the front side of the control device. With such connecting arrangements, if the control apparatus with the control panel is arranged at various heights, then the control panel cannot be optimally placed and operated.
OBJECTS OF THE INVENTION
An object of the invention is to provide a connecting arrangement for connecting a control apparatus with a control panel that overcomes some of the problems and shortcomings of the prior art.
Another object of the invention is to provide a connecting arrangement for connecting a control apparatus with a control panel whereby the control apparatus and the control panel form separate units, but can be connected to each other in a simple manner, providing the opportunity to adjust the control panel in a number of angular settings. How these and other objects are accomplished will become apparent from the following descriptions and from the drawings.
SUMMARY OF THE INVENTION
The connection of a control panel to a control apparatus is accomplished according to the invention in that the connecting arrangements are formed as angled pieces that each have a first and a second leg part. Such leg parts are joined together around a shaft that is oriented parallel to the lower edge of the control apparatus in such a manner as to allow the leg parts to be adjusted and fixed in a number of angular settings around the shaft.
By constructing the connecting arrangements as two angled pieces a simple connection is achieved between the control apparatus and the control panel. The angular position between the control apparatus and the control panel can easily be changed and fixed by means of the shaft. It is therefore possible to optimally adjust the control panel at various structural heights such that it is readily visible and operable.
In order to easily attach the connecting arrangement it is provided, according to one embodiment, that the free ends of the leg parts of the angle pieces be connected by means of frames that surround the front side of the control apparatus and the upper side of the control panel. A form-locking transition is thus ensured, in that the free ends of the leg parts are adapted to the contour of the frames.
In one embodiment of the inventions, the connections is characterized by the fact that the frames for the control apparatus and control panel are constructed of frame members and corner connectors. The corner connectors each have at least one screw receptacle, and the fastening screws are secured in the screw channels that are provided in the corner connectors. This allows the fastening screws to be lodged in a covered manner in the leg parts and the corner connectors. The frame members of the frame for the control apparatus and the control panel can be designed, as in the past, using extruded profile pieces, since only the facing corner connectors need to be fit and provided with screw channels.
In order to fix both swiveling leg parts of a connecting arrangement it is provided, according to one embodiment, that the ends of the leg parts of the angle pieces that face each other are formed as bearing flanges. Such bearing flanges are provided with a threaded bore or a receptacle for a connecting screw or a connecting lever.
This embodiment allows the adjustment of the angular setting to be undertaken in a stepped manner that can be arrested if the bearing flanges of the leg parts are provided with teeth that mate on the sides that face each other. In such embodiment, the teeth are arranged around the shaft (i.e., the threaded bore hole
