Description

Technical field

The invention relates to a method for operating 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 actuating element, which consists in particular 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 when the most light penetrates through the blind to the closed vertical position when the least light penetrates through the blind is accomplished by manually attaching and pulling the back / front of the loop of this control.

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 roller shutter holder, where the rear and front end connectors are terminated. This device provides for the tilting of the blinds 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 around 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 the method of controlling the horizontal blind and the device for practicing this method, in particular in the case of a window blind, which is generally fixed by a bracket in the upper part of the frame and which uses a rod which mainly consists of a ball chain / lanyard. the principle of which 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 opposed 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, optionally 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).

The rear linkage 132 of the actuator 2 is detachably fastened to the rear handle 131 of the movement unit 13 of the device 1 and the front linkage 132 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 connected to the control unit U is a motor 12 and a movement unit 13 with a rear mount 131 and a front mount 132 attached 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, the rear grip 131 of the device 1 with the rear chain 21 of the actuator 2 fixed. in the lower position and the front grip 132 of the device 7 with the chain of the front linkage 22 of the actuator 2 fastened is in the upper position.

In order to make the required amount of light penetrate through the louvre 3, the direction switch 111 is instructed by a mechanical switch or by an electronic pulse of other elements of the direction switch 111 (not indicated in the figures), to the control unit H. the point in time when the gear 1332 rotates and moves the ridge rails 1331 with the grips 131, 132 to the defined positions. The rear handle 131 with the rear linkage 22 fixed and the front handle 132 with the front linkage 22 fixed are displaced in opposite directions 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.

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 the one hand, is attached to the trapezoidal grip 1351 and on the other, it is mounted via the couplings 1353 on the axis of the motor 12. When the engine 12 is switched on for a certain period of time, the trapezoidal rod 1352 will rotate and

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 (indicated in FIG. 2) are connected by a spring gear assembly 136 which consists of a double-torsion 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 by a spring coupling 1361 on the motor shaft 12.

SK 6066 Υ1

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.
