Description

The present invention relates to a door drive according to the preamble of claim 1. The present invention is also directed to a mounting procedure for the door drive object of the invention.

An example of a known door drive is disclosed in EP 1801339 A.

The drives for building doors, often referred to as door openers or door closers, are generally arranged or recessed above the door leaf or in the floor area, next to the door frame, and can be made , or only with an elastic force accumulator, with an electric, electro-hydraulic or fully automatic motor drive. In the case of fully automatic door actuators, these are generally activated to open the door by means of a push button or a movement alarm, and serve not only to carry out the opening process but also the closing process of the door leaf , generally deferred over time. Door openers are also known which are connected to a power supply network of the building to form a component of the safety installations, and in particular of the fire protection installations, and which can be activated centrally. Especially in public buildings and buildings of great importance in terms of infrastructure, which are frequented by a large number of people, fully automatic door closers are widespread.

For the placement of a door drive, it has a base plate which, by means of screwing or any other known connection elements, joins the door's lintel, the wall or the door frame. Once the base plate is mounted on the wall or on the door frame, the door drive itself is mounted on the base plate. It has prefabricated threaded holes or through holes for screws for mounting the door drive in order to be able to join the door drive through the base plate firmly with the wall or with the door frame.

A generic motherboard for a door closer is known from the utility model memory DE 20 2005 000 543 U1. The base plate is made for a door closer and can be fixed on a sturdy bottom. The door closer assembly as well as the corresponding cover can be mounted on the mounting side, the base plates for door openers, for door closers or door drives with different degrees of automation being similarly made.

The door drive must be mounted on the base plate frequently in an anti-ergonomic working position. This requires work above the head, taking into account that a door drive with a high degree of automation has a considerable weight of its own. To this it must be added that also within a building a plurality of different door drives must be mounted that must be adapted to the respective point of use of the door being operated. In addition to different embodiments in terms of the degree of automation, from the simple door opener / door closer to an electric door opener to a fully automated door drive with an opening sensor system, it is necessary to use different door openers. dimensions, which for differently made doors must provide opening pairs of different magnitude. This results in a considerable plurality of variants of various door openers and corresponding systems, which generally have base plates made in different ways.

Depending on the embodiment of the door drive, base plates are known on which the respective door drive must be mounted before mounting it on the wall or on the door frame, so that in the case of a plurality of door openers within a building requires an accurate prior determination of the respective door drives for the corresponding doors to be operated. In addition, in the case of pre-assembled door drives, in addition to considering its high weight and the consequent difficulties for assembly, it is no longer possible to modify the specification of the door drive at the respective point of use.

Therefore, it is the objective of the present invention to create a door drive that overcomes the problems of the aforementioned state of the art and allows simplified assembly with greater flexibility in terms of the specifications of the door drive.

This objective is solved, starting from a door drive according to the preamble of claim 1 in combination with the identifying characteristics. Advantageous improvements of the invention are described in the dependent claims.

The invention encompasses the technical doctrine that the construction of the door drive is made of a modular nature, and has at least one connection module, one drive module and one main module, which can be interlocked on the base plate by means of the corresponding interlocking means.

With the construction according to the invention based on different modules it can be achieved that firstly the base plate can be fixed on the door frame or on the wall, and only then the door drive is flexibly made as soon as to the necessary specifications. For this, the various modules comprise interlocking means, so that the connection module, the drive module and the main module can be interlocked with the base plate, either individually or together. The interlocking can be carried out in such a way that it also allows the different modules of the motherboard to be released again. The person in charge of mounting the door drive can fit under elastic pressure by means of the interlocking means and according to a modular system the different modules, either simultaneously or consecutively over time on the base plate, so that the modules are already attached to the base plate thanks to the elastic pressure mounting means. Consequently, a considerable simplification of the assembly process is obtained, since the person in charge of the assembly does not have to hold the door drive on the one hand and screw it on the other hand with a tool on the base plate. It can also be carried out by means of the modular system created a possible adaptation of the door drive to a certain construction space without previously preparing a specific door drive, even still during or after assembly.

Interlocking means are provided between the connection module, the drive module and / or the main module, which eventually allow the modules to interlock. In this way the construction of the door drive can be completed, that is to say an drive unit formed in this way, even before interlocking with the base plate, so that in a simplified way the connection establishment can take place electrical modules between each other, after interlocking. After the construction is pre-made, it is interlocked on the base plate by means of the aforementioned interlocking means. The interlocking of the different modules, both with each other and also with the base plate, represents a considerable saving of time during assembly, since it is possible to dispense with a cumbersome screwing, at least during the prefabrication of the construction. In this way, the drive unit can be completed in a workshop, that is to say during production, and then subjected to a final check and possibly an operation check. Therefore this should not be done in situ, for example in a work.

An advantageous embodiment of the interlocking means can be formed by swivel neck-shaped interlocking hooks, which are made to fit in an opposite interlocking hole. For this purpose, the swan-neck interlocking hooks are preferably located in the base plate, while the interlocking holes are made in the modules. The joint action of the swan-neck interlocking hooks and the interlocking holes adapted thereto takes place in accordance with the known elastic connection principle, so that a positively coupled joint of the modules is established with each other. as well as between the modules and the motherboard. The position of the interlocking hooks can be provided in such a way that they are accessible manually, so that when the interlocking hooks are operated in the opposite direction of the coupling it can be possible to re-release the modules of the base plate or the modules with each other. The interlocking hooks can be made on the base plate so that they are made in a single piece with the body of the base plate. The base plate can be made, for example, of a plastic-injected casting material, so that the interlocking hooks are molded into the body of the base plate. In an embodiment of the base plate of a sheet material there is the possibility of forming the interlocking hooks of the base plate material by means of die-cutting operations, so that also in the sheet metal variant of the base plate the hooks of interlocks are made in one piece with this one. Interlocking hooks can also be provided that are attached as an individual piece to the base plate by known joining techniques. The interlocking holes are made in the modules, which coincide with the position in the plane of the motherboard. The interlocking holes have at least one interlocking edge against which the swan neck-shaped interlocking hooks are carried after snapping to obtain a positively coupled seat.

In another embodiment, it is also possible to imagine a kinematic inversion in which the interlocking means are provided as interlocking hooks located in the respective modules, so that the interlocking holes are made in the base plate. Consequently, the interlocking of the modules with the base plate takes place in the same way, and one or more interlocking means can be provided for each of the modules.

In another embodiment of the door drive according to the invention, it is provided that corresponding threaded joints are provided between the modules and the base plate that have screws, which are located in the respective module impermissibly by means of a loss insurance. Loss insurance can be placed in the form of a bushing on the screw shank after the screws have been inserted through screw holes prepared in the modules. The placement of the screws and the corresponding loss insurance takes place before the interlocking of the modules on the base plate, so that after the interlocking of the modules on the base plate, the screws necessary for screwing are already present at the point connection provided to screw with the base plate. These are aligned with threaded holes made in the base plate in such a way that after the interlocking of the modules on the base plate the screws simply have to be screwed by means of a screwdriver or similar tool, an Allen wrench or a cordless electric screwdriver. This can be done in a simple and ergonomic way without the person having to hold the door drive construction by hand during assembly. After tightening the screws, the mechanical assembly is finished, being optionally only necessary to establish an electrical connection with the power supply network of the building, and to place a protective cover corresponding to the door drive.

To establish an electrical contact between a power supply network or a control network of a building and the door drive, the connection module has at least one plug connection. In this way the connection module serves to establish the electrical contact between the power supply network of the building and the door drive, and not only the general power supply but also a power connection can be established through the plug connection signals between a building control network and the door drive.

The drive module comprises at least one reducer and one motor, the motor can be supplied with power through the main module. Alternatively, the power supply is carried out directly from the aforementioned power supply network, ie without the main module being interleaved. The drive module itself can also be made modular in terms of the reducer and the motor, the modules being able to join and / or release each other through a unitary interface. The drive can be carried out as an electric, hydraulic, electrohydraulic and / or pneumatic motor drive, or be carried out in accordance with other known principles of action. The drive module can also have an elastic force accumulator that, during the door opening process, accumulates a potential energy through an elastic element, by means of which the subsequent door closing process can be carried out. The elastic force accumulator can also act together with the door leaf by means of the reducer. Thanks to the modular construction of the drive module, you can also choose the way the motor is built without having to change the way of construction of the gearbox, as long as the interface between the motor and the gearbox is made the same according to the modular principle.

The main module has at least one power supply or a transformer, a switch unit and a main circuit board, so that the main module forms the electrical power and control unit of the door drive. The main module is made with a support body in which the power supply or the transformer, the switch unit and the main circuit board can be accommodated in a modular way. Accordingly, the main module can also be adapted in accordance with the respective specifications of the door drive, by incorporating into the support body the respective embodiments of the power supply or the switch unit. Also the main circuit board can be adapted according to the specifications of the door drive or the corresponding main circuit board can simply be applied on the support body, without adapting or choosing it correspondingly for the formation of the main module. This results in a door drive that is essentially formed by the three modules mentioned, that is, the connection module, the drive module and the main module. These modules are also made with a submodular character, being composed of the aforementioned components such as the reducer, the motor, the elastic force accumulator, the power supply, the switch unit and / or the main circuit board. As a result, a highly flexible system is obtained to form a door drive which, in terms of the necessary specifications, can be adapted in the simplest way to the respective application or place of use, even during assembly.

The present invention further relates to an assembly procedure for a door drive having the assembly phases according to claim 11. The process can end with the establishment of electrical connections with the building's power supply network, as well as with the placement of a protective cover over the door drive.

Other measures that improve the invention are set forth below together with the description of a preferred embodiment of the invention, using the figures.

In figure 1 a door drive 1 of modular structure according to the present invention is shown, in a perspective view without cover or housing. Several modules comprising a connection module 3, an actuation module 4 and a main module 5 are arranged on a base plate 2. The modules 3, 4 and 5 are held on the base plate 2 with several interlocking means 6, being The elastic pressure connection of the modules 3, 4 and 5 is also shown to each other by means of the locking means 7.

The modules 3, 4 and 5 are composed of several individual components, the main module 5 being formed by a support body 18 in which a power supply 15 and a main circuit card 17 are located. On the end side Switch units 16 that can be operated manually are located in the support body 18.

The drive module 4 is essentially composed of a reducer 13 and a motor 14, the interlocking means 7 being represented by way of example between the drive module 4 and the main module

5. On the end side of the drive module 4, the connection module 3 is coupled with elastic pressure, it being possible to make the connection between the connection module 3 and the drive module 4 also by means of the use of interlocking means.

Figure 2 shows the main module 5, which is essentially composed of the support body 18 in which the power supply 15, the switch units 16 and the main circuit card 17 are arranged. The locking holes 9 necessary to establish the interlocking joint are made in the support body 18, in which the interlocking hooks 8 of the base plate can be engaged. The interlocking means 7 are formed on the support side 18 to establish an interlock connection with the drive module 4.

Figure 3 shows a perspective view of the base plate 2, which has a reinforcement structure 23, and which can be made of a sheet material or an injected plastic casting material. In the base plate 2 several interlocking hooks 8 are formed, located on the base plate 2 in positions chosen by pairs facing each other in each case. The interlocking hooks 8 serve both for the interlocking of the drive module 4 and also of the main module 5 (see FIG. 1 in this regard), it being also possible to interlock the connection module 3.

To screw the modules 3, 4 and 5, the base plate 2 has several threaded holes 22, comprising countersunk holes that allow a simpler insertion of the screws in the threaded holes 22. The base plate also has a plurality of other holes and shapes geometric shapes that serve, for example, to support a cover, which is placed as a finish on the construction of the door drive.

Figure 4 shows a perspective view of the connection module 3, in which a plug connection is located

12. The plug connection 12 comprises several cable connector devices and thanks to the modular embodiment it can be used in various door drives. A housing of the connection module 21 of the connection module 3 is formed by a cast iron component injected with plastic, the plug connection 12 being arranged on a circuit board inside the housing of the connection module 21, and held therein.

Figure 5 shows a perspective view of the drive module 4, connected with elastic pressure with the connection module 3. The drive module 4 is essentially formed by the reducer 13 and the motor 14, extending from the casing of the reducer 13 a output shaft or closing shaft 20, in which a linkage or the like is arranged to form or establish an active connection with a door leaf. The motor 14 is flanged by the outlet side to the reducer 13, the drive module assembly 4 having an elongated structure, which, regardless of the closing shaft 20, does not protrude from the dimensions of a flange side that sits with the base plate 2. Consequently, a cover can be placed on the construction of the door drive 1 that is adapted to the occupancy measures or volumes of the modules.

in which the power supply 15, the switch units 16 and the main circuit card 17 are placed. The power supply 15 has a metal housing that has a groove structure to achieve an air convection to its cooling The main circuit card 17 is placed on the upper side on the support body 18, the switch units 16 being located on the end side, so that it can be operated by an operator, for example to connect and disconnect the door drive. For mounting the main module 5 on the mounting plate, screws 10 are provided which are secured by means of a loss insurance 11 inside a screw hole in the support body 18. Loss insurance 11 extends in the form of a socket around from the threaded stem of the screws 10 and prevent the screws 10 from falling out of the corresponding screw hole. Loss insurance 11 is each in contact with a screw 10 which is to be held securely, so that the respective screw is simply secured due to friction between screw 10 and loss insurance 11, and of this mode is prevented from leaving. The screw holes are located on that side of the support body 18 that contacts the mounting plate. So that the screws, which are preferably made as Allen screws, can be operated with a tool, the support body 18 has in its necessary places a channel for the tool 24, through which an Allen key can, for example, pass.

The invention is not limited in its embodiment to the preferred embodiment described above. Rather, it is possible to imagine a number of variants in which the represented solution is used, although the realization is basically different. For example, there is the possibility of making the interlocking means 6 that allow the connection with elastic pressure of the modules 3, 4 and 5 with the base plate 2, in one piece with the loss locks 11 of the screws 10. The locks against losses 11 can advantageously be perfected as an elastic pressure joint, so that the interlocking hooks 6 shown acting together with the interlocking holes 9 can be dispensed with. For example, loss locks 11 can have an outer contour that have an annular interlocking contour, so that modules 3, 4 and 5 can be mounted with elastic pressure on the base plate 2 by means of loss locks 11, and at the same time loss locks 11 retain the screws 10. Loss insurance 11 can be made individually or molded in the respective module 3, 4 or 5 or in the support body 18 , with the same material.
