DESCRIPTION:
BRIEF SUMMARY
PRIOR ART
The invention relates to a housing for receiving electric drives, in particular garage-door drives, and the control means therefore. A housing of this type, as is known, for example, from DE-PS 30 12 465 or DE-PS 37 26 685, on the one hand receives subassemblies, such as electric motor and gear mechanism, power supply unit, circuit boards or lighting devices, and, on the other hand, constitutes a link between the force-transmitting elements and the static peripherals, for example, a garage ceiling or a garage door. Such a housing thus has to be of a solid design and have enough space and fastening means for the individual subassemblies.
It is known, from DE-OS 32 03 577, to fasten the drive on a support and to cover it by a protective cover which is screwed onto the support.
Since systems with housings of the type mentioned in the introduction are commercially available and can thus be acquired and mounted by anyone, the intention is to provide a housing which permits the simple and reliable mounting of the entire system, receives individual subassemblies in a space-saving manner, can be assembled without special tools and, of course, complies with the safety regulations which are in force.
SUMMARY AND ADVANTAGES OF THE INVENTION
According to the invention there is provided a housing for receiving an electric garage-door drive and the control means thereof, which housing exhibits at least two housing parts, wherein the housing parts exhibit latching means and guide elements for the reliable connection of the housing parts and for latching-in and retaining at least one functional component and at least one circuit board for the control means. The housing according to the invention with the defining features as mentioned above facilitates assembly in that the housing itself and the functional components to be received by the housing, such as power supply unit, lighting device and the like, can be plugged in in a simple manner and are then arrested by self-closing latching means. These may, if required, be demounted again just as simply.
By virtue of the shape and size of the latching means, which have to be adapted to the geometry of the corresponding functional components, defective insertion of the functional components into the housing is avoided effectively. Furthermore, the number of the additional fastening means, for example screws, rivets, clamps and the like, which have to be handled individually and can go missing can be reduced considerably.
By way of the further disclosed features, further, advantageous refinements of the housing according to the invention disclosed above are possible. Particularly simple mounting and demounting is possible if the latching means engage one in the other within the housing and at least one housing part exhibits openings in the region of the latching means, through which openings said latching means can be unlocked by means of a tool. A special tool is not required for this purpose; all that is needed is a tool with a narrow shank.
If resilient elements are integrally formed on the housing part which receives the functional components, which resilient elements press the functional components, in the installed state, against the latching elements, a secure interconnecting arrangement is ensured. Moreover, size tolerances may be compensated. Upon installation of a transformer, the laminated stack can be clamped in between the latching means and the resilient elements, and noise caused by vibration is avoided in this manner.
It is particularly advantageous if a housing part exhibits a translucent cover which is connected rotatably or pivotably to, and can be latched in, the housing part and by way of which the lighting means of a lighting device can be exchanged. Said cover may be part of the housing part and be connected in a movable and captive manner to said housing part via a defined bending point, a so-called film hinge. This means that the entire housing part does not have to be demounted if the lighting device fails.
