DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
a) Field of the Invention
The invention is directed to a swivel lever closing device for doors of housings or cabinets which preferably have walls of thin material such as sheet steel, in particular for operating locking systems such as locking bars which can be installed in the fold space in sheet-metal cabinet doors, which swivel lever closing device is formed of a door plate which has a base plate with a swivel lever serving as a handle and with protuberances serving to engage in cut outs in the door, wherein a first protuberance is formed at one end of the door plate in the region of a locking arrangement for the swivel lever and another or second protuberance is formed at the other end of the door plate and is arranged at the door plate symmetrically with respect to rotation so as to be offset by 180.degree. with reference to the actuating axis of the swivel lever, wherein a locking bar is provided which is in a working connection, through a latch, with the swivel lever and an articulated spindle pinion and with receptacles in the cabinet for locking elements formed in the region of the locking bar.
b) Related Art
A swivel lever closing device of this type is already known from EP 0504044 A1.
This closing device represents an improvement over a closing device known from EP 0261266 B1. The dosing devices known from these two publications are provided for switch boxes, but also for cabinets or housings which are used in work places for electronics and other technical fields to house electronic devices or components. Such cabinets or housings usually have construction dimensions of 19 inches, but can also be manufactured in metric sizes. The use of especially narrow counter-folds has proven advisable to provide a usable interior space which is as large as possible and easily accessible. For example, a narrow hollow section serves as a mounting frame to which side walls or rear walls and doors are attached. Alternatively, switch boxes formed from bent sheet metal can also be provided, these switch boxes having a folded region in which locking devices, e.g., bar locks such as are already known from the cited references, are advisably accommodated. In the swivel lock device known from EP 0261266 B1, the base plate comprising the door plate is so disposed in the door leaf plate provided in the region of the swivel lever articulation that one of its protuberances or shoulders is arranged in a first rectangular opening, while a second protuberance or shoulder is provided for receiving a cylinder lock supported in the free end of the swivel lever. The described dosing device and its base plate, respectively, have the same approximate length as the swivel lever. The two openings are arranged so as to be axially symmetrical with respect to the longitudinal axis and the closing device can accordingly be installed in these two rectangular openings of identical dimensions in such a way that it is possible to switch from the right-hand side to the left-hand side. However, the lock itself is arranged eccentrically. This eccentricity in the drive region has disadvantages. In contrast, the closing device according to EP 0504044 A1 has three rectangular openings of identical dimensions, the center opening being arranged centrally with respect to the door plate as is shown in FIG. 14 of this reference. The known swivel lever closing devices can be used for different door closures, but their use in combination with bar locks, especially with flat bar locks, is particularly advantageous because this provides particularly favorable opportunities for accommodation in narrow profile spaces such as in the fold space in sheet-metal cabinet doors.
The door plate is fastened by means of projections on its base plate which can be inserted into the openings of the door leaf, these openings being rectangular in particular and having identical dimensions, or which engage behind the openings or by means of a cap part or retaining part which is screwed on from the inside of the door (as is the case in EP 026
