Description

A method for controlling a horizontal blind and an apparatus for performing the method

Technical field

The invention relates to a method for controlling a horizontal blind, in particular a window blind, and to a device for carrying out the method.

BACKGROUND OF THE INVENTION

Several methods of controlling blinds and structures for their implementation are currently known.

These include, in particular, a method of operating horizontal louvers mounted mainly on windows, which is based on a structure consisting in that the louvre is composed of a plurality of interconnected slats, where such an interconnection allows them to be rotated from vertical to horizontal. The ends of the operating element, which in particular consists of a ball chain or string, which can advantageously form a loop, are fastened to the connection of the rear of the lamella and the front of the lamella. The actual rotation of the slats from the open horizontal position where most light penetrates through the blind to the closed vertical position, where the least light penetrates through the blind, is accomplished by manually gripping the back / front of the loop of this control and pulling it.

The disadvantage of this method and construction is, in particular, that the control requires a person to access the window at a particular point in time when there is a need to open or close the blinds and does not allow the blinds to be operated from elsewhere in the object or without the person in the object.

Also known is a method of operating blinds and a device for its implementation, which partially removes the described drawbacks. Its construction consists in that a mechanical device comprising a rotating shaft with an electric motor is installed in the blind holder where the connectors of their rear and front parts are terminated. This device ensures that the blinds are tilted to the desired position, the electrical part of which is usually installed around the window frame.

The disadvantage is the complexity of the construction and assembly with interventions in the frame and surroundings of the window for the introduction of the electrical installation, which is unfavorably reflected in the cost of its construction.

The essence of the technical solution

The aforementioned drawbacks are largely eliminated by a method of operating a horizontal blind and a device for practicing this method, in particular for a window blind which is generally fixed by a bracket in the upper part of the frame and which uses a drawbar as a control. the principle is that the movement unit of the motorized device carries out the rotation of the set of louver slats. This device converts the rotational movement of the engine into a linear movement of the front and rear mounts, which are attached to the opposite parts of the actuator loop.

To open or close the blind, move both handles.

The movement of the rear handle with the attached rear linkage is opposite to the movement of the front handle with the attached forward linkage and synchronized with each other.

The device for carrying out the method of controlling the blind consists of an electronic control unit which is connected to a motor and the motor is connected to a movement unit.

The movement unit has a front and a rear grip for securing the blind control. The control unit is also connected to a battery and a directional switch which is either mechanical or electronic with a remote control capability and preferably also comprising a light sensor and / or a timer with the possibility of programming a switching schedule.

The movement unit is preferably formed by a rack-and-pinion gear assembly, alternatively also by a trapezoidal-gear assembly, a belt-gear assembly, or a spring-gear assembly.

The advantage of the described method and apparatus lies in the simplicity of the construction allowing automation of the blind control process and easy installation, as well as an additional device for already installed manually operated blinds.

EXAMPLES

Example 1

The structural arrangement of the system for performing the blind control method is shown in FIG. 1, wherein the motorized device 1 is mounted on the sash 4 of the window. The Venetian blind 3 itself is composed of a plurality of slats 31 and is fastened in the upper part of the sash 4 of the window by means of the Venetian holder 32. The lamella assembly 31 has its rear portion 311 interconnected and led to the rear linkage 21 of the actuator 2 and its front part 312 interconnected and led to the front linkage 22 of the actuator 2. The actuator 2 is made of a ball chain and forms a loop through its interconnected lower portion. not indicated in the figures).

A removable rear linkage 21 of the actuator 2 is detachably mounted to the rear grip 131 of the movement unit 13 of the device 1, and the removable front linkage 22 of the actuator 2 is removably attached to the front handle 132 of the movement unit 13 of the device 1.

The device 1 (shown in Fig. 2) comprises a control unit 11 to which the battery 14 and the direction switch 111 are connected. The connection of the direction switch 111 to the control unit 11 is realized by a wired connection, the direction switch 111 being a mechanical switch and / or a light sensor and / or a temperature sensor and / or a timer (not indicated in the figures).

Further, a motor 12 is connected to the control unit 11 and a motion unit 13 with a rear handle 131 and a front handle 132 is connected thereto.

As indicated in FIG. 3, the mounts 131, 132 of the motion unit 13 are connected to the motor 12 by a rack and pinion assembly 133 consisting of two opposing racks 1331 and a gear 1332 mounted on the motor shaft 12.

The description of the method of operating the blind 3 is based on a state where the slats 31 (shown in Fig. 1) are placed in a vertical position, with at least light penetrating through the blinds 3, with the rear grip 131 of the device 1 with the chain in the lower position and the front grip 132 of the device 1 with the front linkage chain 22 of the actuator 2 fixed therein is in the up position.

In order to obtain the desired amount of light through the louvre 3, the directional switch 111 is touched by a mechanical switch or by an electronic pulse of other elements of the directional switch 111 (not indicated in the figures), instructing the control unit 11 to turn the motor 12 on the moment when the gear 1332 rotates and moves the racks 1331 with the mounts 131, 132 to the defined positions. The rear bracket 131 with the rear linkage 22 attached and the front bracket 132 with the front linkage 22 attached are oppositely displaced and the louvers 31 of the blind 3 are thereby rotated to the desired position.

To restore the initial state, the process is repeated except that a different instruction is given in direction switch 111.

Example 2

It is identical to Example 1 except that, as indicated in FIG. 4, the mounts 131, 132 of the motion unit 13 to the motor 12 (shown in FIG. 2) are connected by a belt drive assembly 134 that consists of a toothed belt 1342 on which the mounts 131, 132 and two pulleys 1341 are attached one located on the motor shaft 12 and to the control unit 11 the direction switch 111 is connected wirelessly (not shown in the figure).

When the engine 12 is switched on for a certain period of time, the toothed pulley 1341 rotates with the belt 1342 and moves the handles 131, 132 to the defined positions.

Example 3

It is identical to Example 1 except that, as indicated in FIG. 5, the mounts 131, 132 of the motion unit 13 to the motor 12 (shown in FIG. 2) are connected by a trapeze gear assembly 135 consisting of a trapezoidal rod 1352 divided into two counter-rotating threaded parts on which the mounts 131, 132 are mounted; and which on one side is fixed to the trapezoidal mount 1351 and on the other side it is mounted on the motor shaft 12 via the couplings 1353.

When the motor 12 is switched on for a certain period of time, the trapezoidal rod 1352 rotates and moves the handles 131, 132 to the defined positions.

Example 4

It is identical to Example 1 except that, as indicated in FIG. 6, the mounts 131, 132 of the motion unit 13 to the motor 12 (shown in FIG. 2) are connected by a spring gear assembly 136 that consists of a twist spring 1362 inside which the mounts 131, 132 are mounted and which is mounted on one side to the spring clip 1363 and from the other side is mounted on the motor shaft 12 via a spring coupling 1361.

When the motor 12 is switched on for a certain period of time, the spring 1362 is rotated and the grips 131, 132 are moved to defined positions by means of counter-rotating threads.

The examples are not the only application examples of the method and apparatus according to the present invention, and a combination of part of the described examples is not excluded.
