Description

Technical area

The present invention relates to a door drive for completely opening and / or closing a door or a like type opening element, comprising at least one on the door leaf and on the door frame via a connecting element articulated and linear linear drive element.

State of the art

The DE 29700583 U1 discloses a door opener and closer that places a door in the open or closed position, wherein a mounting bracket with an adjustment plate disposed thereon is attachable to the door frame. Furthermore, a motor, pneumatic or hydraulic drive device is provided between the adjusting plate and a holder arranged on the door leaf. The mounting bracket in this case has an elongated hole for the adjustable mounting of the adjusting plate.

The US 2001007163 A1 describes a door closer with a power cylinder and arranged on the door leaf damping, which counteracts the force of the power cylinder. The power cylinder is in this case rotatably mounted on the door frame via a fitting and on the damping.

Similar devices are also in the DE 202008015539 U1 and the US2002026684 A1 disclosed.

From the US 2008116771 A1 an opening support device for a cover of a piece of furniture is known, wherein on the cover a rail with damping, Feststellklötzen and a carriage is arranged, wherein the carriage a power cylinder is rotatably mounted.

Presentation of the invention

The present invention is based on the object to provide a door drive, which is suitable to bring a door in the open or closed position, to avoid that the door leaf is in a partially open position, and this no additional locking device (wedge etc.) is required to hold them in the open position, thereby ensuring that always the whole width of the door is available and a self-closing eg is prevented in drafts.

According to the invention the above object is achieved according to the preamble of claim 1 in conjunction with the characterizing features. Advantageous embodiments and further developments of the door drive according to the invention are specified in the dependent subclaims.

According to the invention, a door drive of the aforementioned type is characterized in that the connecting element comprises at least one guide part on / in which the linear drive element is displaceably arranged in the longitudinal direction of the door frame.

In a further advantageous embodiment of the invention, the connecting element comprises at least one further guide part, on / in which the linear drive element is displaceably arranged in a substantially orthogonal direction to the door frame.

For this purpose, in a preferred embodiment of the invention, a mounting bracket for the adjustable mounting of an adjusting plate is provided, wherein the adjusting plate is provided for the adjustable mounting of the linear drive element in each case with a slot.

Preferably, the linear drive element is a power cylinder, wherein this is rotatably supported by joints on the one hand on the adjustment plate and on the other hand on a carriage, which is located in the guide rail. This embodiment may further be characterized in that the end position of the carriage is infinitely adjustable by means of locking blocks with locking screws.

A further advantageous embodiment provides that the damping is designed as a spring, rubber damper, gas damper, or frictional resistance.

Preferably, the linear drive element can optionally be designed with and without adjustable actuating force. A further embodiment provides that the linear drive element is designed optionally with and without adjustable operating speed. This last embodiment of the invention has an advantageous variant, in which the linear drive element has a maximum actuation speed.

The door operator can be retrofitted to any type of door, gate, window or similar rotatably mounted element, left and right, inside (variant 2) and outside (variant 1). The end position of the opening angle (up to 180 °), the speed, the actuating force and the dead center between opening and closing can preferably be infinitely regulated.

Embodiment of the invention

• 1. Der Endanschlag des Türblattes kann stufenlos bis 180° eingestellt werden.
• 2. Der Überlastschutz in Form einer Feder 8, eines Dämpfers, durch Reibwiderstand oder durch Magnete verhindert eine Beschädigung beim Öffnen über den Endanschlag.
• 3. Durch Lösen der Feststellschrauben 7 wird das System außer Kraft gesetzt und die Tür kann wie gewohnt geöffnet und geschlossen werden.

The mounting bracket 1 (which in variant 1 on the doorstep 9 or in variant 2 on the door leaf 10 attached) and the mounting plate 2 are equipped with slots in order to adjust the characteristic and the dead center can. In the guide rail 4 , which on the door leaf 10 (variant 1 ) or on the doorstep 9 (Variant 2 ), are adjustable blocks 6 and a damping 8th installed by means of locking screws 7 Various tasks and settings guaranteed.

• 1. The end stop of the door leaf can be adjusted steplessly up to 180 °.
• 2. The overload protection in the form of a spring 8th , a damper, by frictional resistance or by magnets prevents damage when opening over the end stop.
• 3. By loosening the locking screws 7 the system is overridden and the door can be opened and closed as usual.

The power cylinder 3 , which on the one hand on the slide 5 and on the other hand on the mounting plate 2 through joints 11 is rotatably mounted, can be performed with adjustable actuation force and operating speed to adapt the device to the respective door, window, etc. and additionally regulate the speed and the closing or opening force.

The door drive according to the invention is not limited in its execution to the above-mentioned preferred embodiments. Rather, a variety of design variations are possible, which make use of the solution shown even with fundamentally different type of execution.
