BRIEF SUMMARY
DESCRIPTION
The invention relates to a functional component usable for demonstration and/or training purposes in accordance with the preamble of claims 1 or 6.
In order to facilitate the understanding of individual structural elements or whole circuits, it is customary, in particular, in the fields of pneumatics, hydraulics and electronics to employ practical structures. In the case of the embodiment known from DE-GM 75 07 762, a plate-like mounting part is employed which is provided with a plurality of bores in a screen into which the individual functional component can be inserted. Each functional component contains a pneumatic, hydraulic, electric or electronic equipment, for example, valves operating cylinders, manometers, connection sleeves for electrical or pneumatic lines, electronic controls, etc.
The functional components may be mounted in accordance with a circuit diagram and subsequently may be connected with each other in the required manner fluidically and/or electrically.
A device of the aforementioned type is known from GB-A-2 151 387 The device consists of a plate-like support part with a plurality of mounting recesses wherein functional components equipped with functional units are anchorable therein. The functional components have a base body with two yielding shanks which are lockable in a clamped position into the mounting recesses. For removing from the support part, one of the shanks must be manually bent laterally.
The handling of the known functional component is problematic because compromises must be made during the mounting on the support part.
A high prestress which assures a good retaining force can hardly be realized because of the high bending forces required during assembly and disassembly. The stability may suffer with a reduced prestress.
It is an object of the invention to provide a functional component of the aforementioned type which permits a simple handling and a more flexible structure of embodiments will be demonstrated.
This object is solved by the characterizing features of claims 1 and/or 6.
The functional component is designed in such a manner that it is releasably secured on a support base which is provided with at least a groove-like mounting recess. Support bases of this type are known per se, for example, for DE-OS 40 10 840. It may be an injection molded plate-like structural element which is provided with a plurality of linear, parallel extending, adjacent mounting recesses, in particular, extending at the same distance with respect to each other, whereby the functional component can be releasably anchored in a given available mounting recess. A clamping device is provided as the securing device of the inventive functional component which has a clamping component extending downwardly, which, in the mounting position of the functional component, engages the selected mounting recess. In its clamped position, the clamping component is pushed against an upper surface of the mounting recess, so that the functional component is practically fixedly tensioned. For removing, one merely has to actuate the actuating element, so that the clamping component assumes the detachable position and the functional component can be removed from the support base without any problems. A tool is not required because the force of the human hand suffices for actuation. During the mounting on the support base, the clamping component is advantageously maintained in its detachable position by means of the actuation element. With a corresponding design, it may also be provided that the clamping component normally assumes its clamped position and, during insertion into the mounting recess, it automatically moves for a short time in the direction of the detached position, thus practically engaging itself.
The functional component can be arranged stepless at any given position along the given mounting recess and be clamped. One may arrange the device in such a manner that despite being in the clamped position, a certain longitudinal displacement in the mounting recess may be caused with
