There are also already drives of the type mentioned above, in which the drive unit is hung on a fixed Einhängebolzen on one end face and a second, spring-loaded push-button-type Einhängebolzen on the other front side in brackets, including the spring-loaded push-button type Einhängebolzen to hang short, before he can snap into the console in question.

In the previously known drives of the latter type has been shown in practice, however, that by axial forces that may arise during operation of the drive, the spring-loaded push-button mounting bolts can be slowly inadvertently pushed so far that the drive from the console solves what carries the risk that the drive and casement crash and injure persons.

The invention has for its object to provide a drive of the type mentioned, in which the aforementioned disadvantages are eliminated. In particular, a more reliable, secure attachment of the drive unit to the wing or frame should be ensured with the simplest possible and faster installation of the drive.

According to the invention this object is achieved by a drive with the features of claim 1. Preferred embodiments of the drive according to the invention will become apparent from the dependent claims, the present description and the drawings.

The drive for a wing of a window or the like according to the invention comprises a drive unit for moving the wing with respect to a fixed frame by means of a drive element. The drive unit can be attached to the wing or the frame via a holder by means of bolts arranged in the holder on the drive unit. At least one bolt is provided as a spring-loaded in its extended position acted push-button-like bolt. In this case, the spring-loaded push-button-like bolt locking means are associated with the spring-loaded push-button like a bolt against the spring force axially from its extended position in the drive unit can be pressed, and a blocking position are adjustable, in which the spring-loaded push-button-like bolt in its extended position is blocked.

By the drive unit is provided with at least one spring-loaded in its extended position push-button-like bolts, the drive is relatively easy and quick to install. By the spring-loaded druccknopfartigen bolt associated locking means is also ensured that the drive unit can be fastened more reliable and safer on the wing or frame, so that in the previously known drives with on the drive unit provided spring-loaded push-button-like bolt existing danger that the casement crashes and people are injured, is eliminated.

Preferably, the locking means comprise a bolt member which is embedded in the spring-loaded push-button type and rotatable relative thereto in its circumferential direction, being rotatable between a release position in which the spring-loaded pushbutton-type bolt is released and can be pressed into the drive unit and a blocking position in which the spring-loaded member is rotatable Pushbutton-like bolt in its extended position mechanically blocked, that is hindered axial displacement.

By the locking means are at least partially embedded in the spring-loaded druccknopfartigen bolt, the drive can be kept relatively compact overall.

According to an expedient practical embodiment of the drive according to the invention, the spring-loaded push-button-like bolt is mounted in an end cap of the drive member and the rotatable latch member is supported in its blocking position on the one hand on the spring-loaded push-button-like bolt and on the other hand on the end cap.

In its blocking position engaging latch part of the spring-loaded push-button-like bolt is thus axially fixed with respect to the relevant end cap of the drive element.

Preferably, the rotatable latch member is provided with a radial projection over which it is axially supported in its blocking position on the end cap.

According to a preferred practical embodiment of the drive according to the invention, the rotatable latch part comprises a hollow base body into which a Spring unit is used, which is supported on the one hand in the hollow body of the bolt part and on the other hand on the end cap and is acted upon by the spring over the bolt part and the push-button type bolt.

The rotatable latch member can thus be at least partially received in the hollow body of the rotatable latch member with its hollow body in druccknopfartigen bolt and acting on the push-button type spring unit, so that the drive is kept relatively compact overall.

Conveniently, the latch member for transfer from the release position in the blocking position and vice versa at least substantially rotatable by 90 ° relative to the spring-loaded push-button-like bolt.

It is particularly advantageous if the latch member is provided with an accessible from the outer end side of the spring-loaded push-button-like bolt forth recording for a screwdriver or the like over which the latch member is rotatable.

The movement of the latch member and thus its transfer between its release position and its blocking position and vice versa is advantageously controlled by appropriate guideways in the end cap.

Preferably, the latch member is locked in its blocking position with the end cap.

It is thus ensured that the latch member does not rotate unintentionally, for example due to vibrations.

According to a preferred alternative embodiment of the drive according to the invention, the blocking means comprise a spring-loaded push-button-like Bolt arranged latch hook which is provided with detents which are radially outwardly spreadable via a spring-loaded latch key to mechanically block the spring-loaded push-button-like bolt in its extended position, and by pressing the lock button in the spring-loaded push-button-like bolt against the spring force to release the spring-loaded push button-like bolt are releasable.

By the locking lugs provided with the latch hook is arranged in the spring-loaded push-button-like bolt, the drive is held in total again relatively compact.

Conveniently, the spring-loaded latch key is accessible from the outer end face of the spring-loaded push-button-like bolt forth.

The latching lugs of the latch hook, which are radially outwardly spread outwardly for mechanical blockage of the spring-loaded push-button-like bolt, are preferably supported axially on an end cap of the drive element.

It is particularly advantageous if the latching lugs of the latch hook can be moved into its release position while the latch key is pressed by a ring-spring element such as in particular a preloaded O-ring or the like.

The mechanical blocking of the spring-loaded push-button-like bolt in its extended position is thus realized in a relatively simple and correspondingly reliable and secure manner.

According to a preferred practical embodiment of the drive according to the invention, the lock button is supported on the one hand on the end cap and on the other hand in the lock button supported spring unit with the push-button-like bolt maintained in engagement, by means of the lock button and the push-button-like bolt is resiliently acted upon.

The drive is thus handled in a relatively compact structure in a simple manner. If the lock button is pressed, the latching lugs are pulled inwards, for example by means of a ring-spring element, whereby they come free from the end cap, for example, disengage from recesses of this end cap, whereupon the axial movement of the push-button-like bolt is released. Subsequently, the push-button-like bolt can be pressed for mounting in the holder.

Conveniently, the locking hook comprises two locking lugs which can be spread radially outward over the spring-loaded locking button and radially outwardly.

It is thus possible with relatively simple structure a reliable locking of the push-button-like bolt in its extended position.

The drive unit may be provided on its front side with the spring-loaded push-button-like bolt opposite end face, for example with a fixed suspension bolt. In this case, the drive unit can first be hung with the fixed Einhängebolzen on one side in the holder before the spring-loaded push-button-like pin is briefly pressed on the opposite end for hanging in the holder before he can snap into the holder.

The holder may comprise, for example, two spaced-apart consoles or be made in one piece.

In the variant with the rotatable latch member, the movement of the latch member and thus its locking and unlocking can be realized in particular by corresponding guideways in the end cap. The rotation of the latch member may be effected by means of a screwdriver or the like. By the additional locking function of the latch member in the locked state can be prevented that the latch member rotates unintentionally, for example, by vibration.

In the variant with the latch hook is to hang the spring-loaded push-button-like bolt in the holder or the console in question first press the lock button, so that the locking lugs of the latch hook are pulled, for example by the ring-spring element inwards and come free from the end cap, for example, disengage from recesses of the end cap, and release the axial movement of the push-button-like bolt. Subsequently, the push-button-like bolt can be pressed into the drive unit for mounting the drive unit in the holder or the relevant console, whereupon this can snap into the respective recording of the holder or the relevant console. As soon as the push-button-like bolt is released, the sequence of movements proceeds in the reverse order. In this case, the push-button-like pin is pressed by the relevant spring unit from the end cap. By the rotatable latch member or the locking lugs of the latch hook the push button-like bolt is blocked or locked again in its extended position, i. prevented from axial displacement from this extended position.

To spread apart the locking lugs of the latch hook the latch key may be provided for example with a conical slope.
