Abstract

Automatic drive for swing doors is characterized in that a high-ratio DC motor 42 moves with an external gear stage 43/44 g, the connection of swing door 1 to the drive includes a slip clutch 45 and the turntable 46 has a guide cutout 461 for receiving the driving pin 11.

Description

Automatic door opening and closing systems are known. They have the task of automatically opening sensor-monitored doors when entering and closing them automatically after they have passed. The automatic door opening and closing systems on the market are complex and built on a large volume on the door leaf.

They are connected with a hydraulic system (when opening and closing). These systems require by the lever kinematics large spring and drive forces, resulting in a correspondingly technically complex hydraulic damping results. This results in a high cost.

The object of the invention is to open and close a swing door such that the automatic opening and closing mechanism is simple and arranged on or in the door frame and / or in / on the rotary wing.

A cost-effective total solution according to the market is imperative because the door weights in the private living area are not very high and thus the pure moment of movement of the rotary wing can be handled with smaller drive units.

This shows that a simple, space-saving and inexpensive mechanism can be used. Also, the automatic drive for smoke and fire doors should be used. Furthermore, the system for retrofitted swing doors should be retrofitted.

The overall mechanics should also be classified as opening and / or closing means or vice versa. It is important to consider the safety-relevant provisions in the invention.

The solution of the problem is achieved by the rotary door of a door is moved via a highly geared electric gear motor in the opening and closing direction, the actual movement of the rotary wing requires only a relatively small same torque in the opening and closing direction, but the locking torque large should be. The point of application for the introduction of the torque on the rotary wing is as close as possible in the x-direction to the pivot point of the hinges, but in the greatest possible distance in the z-direction. A swivel compensation (pivot point door hinges / pivot point last gear stage) is provided via a long-hole engagement between the rotary wing and driven pulley. Furthermore, a set slip clutch must be provided between the drive and the rotary vane, so that the overall transmission will not be damaged or blocked in the event of overload (eg manual closing or opening of the door). Opening widths of the rotary vane are limited by adjustable limit switches or stops. The fixing of the door in the closed state via a switched by the electronics magnet, which can be arranged in the strike plate. If the swing door is to be opened via the door handle, even though the system is electrically connected, the counter plate of the electromagnet in the rotary vane is pulled back or tilted via the lock and the rotary vane is pressed against the slip clutch. It is also possible to keep the rotary wing locked via an electrically controlled umpolbares magnetic pair, or to generate when opening by reversing a rotary vane opening pressure via magnetic Gleichpolung. Further, it is possible to arrange a controlled electromagnetic pressure pin in the strike plate, which pushes back the latch. If the opening / closing system is de-energized or ignored, the rotary vane can be unlocked via the pusher and moved against the torque of the slip clutch.

The door is lockable by hand. If the automatic opening / closing mechanism works against the locking bolt, the system switches off via the overload electronics. When unlocked, the door can be opened against the slip clutch.

It is also possible, in the opening / closing housing to arrange one or more downwardly directed electrical light source, so that the passage opening is illuminated from one to the other room to mark this area particularly optically. The lighting time (start / end) is controlled by the electronic sensors of the automatic opening / closing mechanism. Also, the room lighting of the room to be entered can be turned on.

The solution of the problem is described in detail by drawings.

The rotary wing 1 is via a highly translated drive 4 in a housing 41 on the transverse frame 21 near the hinges 3 the band side is arranged, moved in the opening and closing direction.

The drive consists of a high-ratio DC motor 42 with at least one gear reduction stage Z1 43 , Z2 44 , The big gear Z2 44 sits loosely on the output shaft 441 and is via a slip clutch 45 frictionally engaged with the turntable 46 over the output shaft 441 connected. In a management excerpt 461 the turntable 46 picks up a driver 11 Standing at the swing door 1 is attached, one.

Above the big gear Z2 44 is an adjustable clamping element 47 arranged, with the pressure over the friction torque of the slip clutch 45 can be adjusted.

The output shaft 441 is in the case 41 stored in stock. turntable 46 and big gear Z2 44 can be configured segment-like.

The DC motor 42 is via a motor mounting bracket 421 on the housing 41 attached.

The electronically controlled magnet 5 is on the frame side in the strike plate 22 or arranged on the stop side in the housing. The rotary wing 1 is with the counter plate 12 of the magnet 5 equipped and can even with activated magnet 5 over the door handle 13 be withdrawn by means of the latch mechanism of the lock.

The downward arrangement of the lighting is not shown in detail in the drawings. As bulbs incandescent, halogen or LED's can be used.
