Description

The present invention relates to a mounting arrangement for a door operator for operating a door, comprising a mounting plate, which mounting plate is adapted for mounting to a receptacle such as a door leaf, a lintel, a wall, a ceiling or the like, wherein the door operator is mounted on the mounting plate ,

State of the art

From the DE 20 2007 005 265 U1 a mounting arrangement for a door operator for operating a door is known, wherein the door operator can be screwed to the mounting plate. The mounting plate is first attached to a receptacle such as a door leaf, a lintel, a wall, a ceiling or the like, so that the screwing of the door operator on the mounting plate then takes place. The mounting plate has threaded holes in which screws can be screwed. The door operator has a housing, the screws being passed through holes in the housing before being screwed into the threaded holes of the mounting plate. This results in a screw connection of the door operator on the mounting plate, which is visible from the outside. To cover the screwed, door operators often cover, which are placed after the installation of the door operator on the housing. This results in a cumbersome arrangement of a lid, without the use of a lid, the screw, which takes place from an orthogonal direction on the mounting plate remains visible to a viewer. Furthermore, a tool is required to make the screw for attaching the door operator to the mounting plate.

The DE 78 25 463 U1 shows a further mounting arrangement for a door operator on a mounting plate, wherein between the door operator and the mounting plate retaining grooves are provided with complementary executed, opposite projections. Thus, the principle of a groove guide or dovetail guide is realized, and the door operator must be pushed laterally onto the mounting plate. Subsequently, a spreading member is tightened in the form of a threaded pin, and it is achieved a pressure between the holding and the projection. As a result, the door operator jams in the direction of insertion, wherein a positive locking geometry is implemented by the groove guide. However, a disadvantage is a required machining of the retaining and the projection. Furthermore, in turn, a tool is required to operate the spreading member, in particular the threaded pin.

It is therefore an object of the present invention to provide a mounting arrangement for a door operator on a mounting plate, which is simple and can be done without tools in particular.

This object is achieved on the basis of a mounting arrangement for a door operator on a mounting plate according to the preamble of claim 1 in conjunction with the characterizing features. Advantageous developments of the invention are specified in the dependent claims.

Disclosure of the invention

The invention includes the technical teaching that the mounting plate has at least one latching means and the door operator at least one counter-locking means, wherein the locking means in the counter-latching means can be latched for holding the arrangement of the door operator on the mounting plate.

The arrangement of locking means and counter-locking means between the door operator and the mounting plate allows a tool-free arrangement of a door operator on a mounting plate. In this case, the locking means may be disposed both on the door operator and on the mounting plate, so that complementary to the arrangement of the locking means, the counter-locking means may also be present on the door operator or on the mounting plate.

With particular advantage, the latching means can be designed in the form of a latching tongue and / or the counter-latching means can be designed in the form of a recess. For latching, the locking tongue can engage in the recess, so that a fixed arrangement of the door operator is already carried out on the mounting plate by the latch. A latching tongue in the present case describes a spring-like element of elongated extent, wherein the latching tongue can form a portion of the mounting plate or the door actuator, which is in particular resilient. The recess forms an undercut or a recess in the door operator or in the mounting plate, so that the resilient latching tongue can snap into the undercut or in the recess. If the locking means snapped into the counter-locking means, an automatic release of the door operator is prevented by the mounting plate.

With further advantage, the mounting plate may have at least one holding section, which engages positively to the clamping arrangement of the door operator on the mounting plate in at least one corresponding counter-holding portion in the door actuator. This ensures that be clamped by a simple positive connection of the door operator on the mounting plate can. In the present case, the clamping arrangement of the door operator on the mounting plate describes a geometrical positive connection, which is, however, determined such that the door operator is already arranged without play and load on the mounting plate. For this purpose, the holding section is provided, which can engage in the counter-holding section. The engagement takes place in such a form-fitting manner that the door operator clamps by the positive connection to the mounting plate. The power transmission, which is necessary for the fixed arrangement of the door operator on the mounting plate, via the clamping engagement of the holding portion in the counter holding section. The locking of the locking means according to the invention in the counter-locking means in the interface between the door operator and the mounting plate is used in particular for captive arrangement, wherein the locking of the locking means in counter-locking means can also be designed as a force-transmitting and therefore exclusive connection between the door operator and the mounting plate.

With further advantage, the holding portion and the counter-holding portion may be formed such that the door operator can be arranged by an orthogonal placement and a lateral displacement on the mounting plate at this. The latching tongue can form a region protruding out of the extension plane of the mounting plate, in particular a resilient region, and / or the recess can form an undercut region in the door operator. Consequently, the latching tongue can be brought by lateral displacement of the door operator on the mounting plate in registration with the recess, such that the latching tongue locked in the recess. With the simultaneous lateral displacement of the holding portion can be positively engaged in the counter-holding portion to provide the clamping arrangement of the door operator on the mounting plate. The lateral sliding movement of the door operator on the mounting plate is carried out so far until the latching tongue is brought into coincidence with the recess, so that the latching tongue snaps into the recess. In snap position of the latching tongue in the recess, the door operator on the desired position on the mounting plate, and at the same time engages the holding portion so securely in the counter holding section that a resilient, d. H. force transmitting connection between the door operator and the mounting plate is reached.

In particular, the mounting plate of a stamped and bent sheet-metal component is preferably formed in one piece, wherein with further advantage the locking means is punched out by at least one punch-bending method of the sheet metal component and / or bent. Further, the holding portion may be made by a punch-bending method, wherein preferably the locking means and the holding portion are made by punched out and bent-out areas of the mounting plate. The holding portion may for example be formed wing-like and bent out of the plane of the mounting plate to engage in a counter-holding portion in the door operator. For this procedure, the holding portion must be bent out of the plane of the mounting plate, since the holding portion would otherwise rest against the receptacle on which the mounting plate is mounted. In order to further achieve that the latching means can snap into the recess in the door operator, the latching tongue must also be bent out of the plane of the mounting plate.

The mounting plate may have an elongated extension, wherein at least one latching tongue has a longitudinal extent, which points in the direction of the elongate extent of the mounting plate. In particular, the longitudinal extent of the latching tongue must point in the elongated extension of the mounting plate, since the door operator is moved laterally above the mounting plate until the latching tongue snaps into the recess in the door operator. Alternatively, the sideways movement of the door actuator over the mounting plate can be made transverse to the elongate extent of the mounting plate to both clamp the retaining portion in the counter-holding portion and to snap the locking tongue in the recess. Consequently, the latching tongue may also be formed transversely to the elongate extent of the mounting plate.

According to a possible embodiment, at least one latching tongue can be arranged centrally on the mounting plate, in particular in the region of an elongate end on the mounting plate.

Alternatively or additionally, at least one locking means may be arranged laterally in the region of a longitudinal edge on the mounting plate, wherein preferably two locking means are arranged on opposite longitudinal edges on the mounting plate. The counter-locking means corresponding to the latching means, in particular the recesses in the door operator, are likewise either centrally, preferably introduced in the region of an elongated end of the door operator or in the side region of the door operator. Thus, each locking means can be brought into coincidence with a recess in the door operator.

The one or more locking means may be designed resiliently, such that this is again releasable by bending action from a catch in the counter-locking means. If the locking means is designed as a latching tongue, it must be bent back in the direction of the plane of extension of the mounting plate back. Thus, the latching tongue can be bent out of the recess in the door operator back to the lateral displacement movement of the door operator in the release direction, in particular in Release direction of the holding section from the counter holding section to release.

The door operator may comprise a housing, wherein the at least one counter-locking means is arranged on the housing. Further, the mounting plate may be enclosed by the housing when the door operator is arranged on the mounting plate. Consequently, the mounting plate for a viewer is not visible when the door operator is mounted on the mounting plate on the receptacle.

In the housing of the door operator at least one opening may be introduced, by which a bending action is made possible on the locking means, in particular by a tool. The opening may for example have the form of a slot which is arranged at a location over which the latching tongue is accessible by means of a tool. If the bending action by means of the tool through the opening in the housing of the door operator, the bend must be performed on the locking means such that the locking means is released from the counter-locking means. In particular, the bending action on the locking means must be maintained by means of the tool, while the door operator is again moved in the opposite direction to the joining direction laterally on the mounting plate. The displacement takes place until the recess is no longer in register with the latching tongue, so that no re-latching can take place when the tool is removed again.

Rather, a number of variants is conceivable, which makes use of the illustrated solution even with fundamentally different types of use. All of the claims, the description or the drawings resulting features and / or advantages, including structural details or spatial arrangements may be essential to the invention both in itself and in various combinations. For example, the first embodiment can be combined with the second embodiment, so that a first latching tongue 12a in the area of the elongated end 16 in the mounting plate 11 is present, being in the same mounting plate 11 in the laterally existing longitudinal edges 17 further snap tongues 12b can be present. The first embodiment shows a center in the mounting plate 11 existing latching tongue 12a , whereby laterally two locking tongues 12a in the area of the elongated end 16 in the mounting plate 11 can be present. Consequently, the housing has 18 two openings 19 on, and both snap tongues 12a would have to experience a bending action at the same time to the housing 18 from the mounting plate 11 to solve again. For this purpose, tools in the form of special insertion forks can be used with a geometry that must match the geometry of the opening (s). Thus, for example, can be prevented that the door operator 10 not with a standard tool, such as a slot screwdriver, from the mounting plate 11 can be solved.

In addition, it can be provided that the openings 19 can be closed with plugs. These plugs can in turn be screw-in stud bolts that require a special tool to get out of the housing 18 to be unscrewed again. Only then can the openings 19 . 20 released to use a tool to lock the locking tongues 12a . 12b subject to a bending action. In particular, it can be prevented that unauthorized persons to the door operator 10 Make adjustments or it will be the theft of the door operator 10 effectively prevented.
