Abstract

The invention relates to an insect-proof protection system for windows, for protecting the indoor space in residential buildings, in office buildings or other buildings. According to the invention, the insect-proof protection system consists of a roller box, a movable net and aluminium guides and is provided with a rotating electric motor (7), supplied by batteries or from the electrical network, whose shaft rests on supports (10) and drives in rotational motion some pulleys (11) on which the threads that close/open the insect-proof net are wound, automatically, as a result of the control of a sensor fixed on the motor shaft which detects the open/closed position of the window, and indicates in a first position (8) down and in another position (9) up, the positions (8 and 9) being fixed on the outer casing of the roller.

Description

DESCRIPTION OF THE INVENTION

Insect protection system for windows

The proposed invention relates to a system that protects against insects inside the space of residential buildings, office buildings or other purpose.

The following insect protection solutions are known:

- fixed insect net - this net is fixed on the window frame. It must be disassembled to release the window gap when needed, then reassembled. It consists of: aluminum frame / frame, mesh fixed to the frame and fixing clips on the window frame.

- mobile insect net - for this net, the frame is fixed to the window frame with hinges that allow easy release of the window gap when needed. closing and opening to the outside of the building is done manually by pulling and gripping, respectively pushing and releasing in / from the lock (clips) mounted on the window frame.

- roller insect net - this net is incorporated in a roller fixed to the upper part of the window frame. The net moves along two side guides and locks manually down by gripping the pull handles on the movable side of the net into the fasteners on its fixed frame. The net is tightened easily by manually releasing it from the fasteners, until the net is rolled into a roll. The roller and the guides are usually made of aluminum.

The disadvantage of these solutions is that the fixed and hinged nets are visible until they are completely removed and require the intervention of the operator (manual) for opening and closing. They must be dismantled and stored when their action is not necessary. As long as they are installed, they spoil the aesthetic harmony of the buildings, being visible from the outside and from the inside. They have a short lifespan by permanent exposure to the harmful action of sunlight, and in winter natural light diminishes. in the case of the roller net the disadvantage is that the roller net also requires the intervention of the operator (manual) for closing and opening.

The technical problem solved by the proposed invention consists in removing the mentioned disadvantages by the fact that, being an automated system with insect net, it is activated and lowered only when needed, respectively only when the window is open. The proposed system does not require operator intervention: each time the window is opened, the mechanism will automatically detect the position of the sash and lower the net to protect the interior from insects, the reaction time being a few seconds, depending on the size of the window.

The elements of the technical solution and the way of operation are presented in the following, as well as in the attached figures 1 and 2:

Fig. 1 shows an open window. Sash 2 - the moving part of the window, is open to the outside of the building, for a clearer picture. The fixed part of the window - the frame 1 is applied to the Automatic Roll Box 6 and the Side Guides 3. The insect net 4 is lowered to protect the room.

in the case with the window closed, the insect net is in the raised position 5.

in fig. 1 and in fig. 2 through the flexible horizontal section of the automatic roller box is shown The rotary electric motor 7. The motor is powered by batteries or mains. The motor shaft rests on the supports 10 and drives in rotational motion the pulleys 11 on which the threads that wrap / open the anti-insect net are wound. A sensor is fixed on the motor shaft indicating in position 8 DOWN ”and in position 9“ UP ”. 8 and 9 are fixed on the outer casing of the roller.

"UP" and "DOWN" are defined at the first actuation, at commissioning. Then the roller acts automatically.

The system allows the net to be locked in the down or up position when needed we want to go through the window gap and the net should not be closed. For example, to replace the power batteries, the mesh blade will be deactivated - up position - tight. In these cases, deactivation is done manually.

The proposed invention has the following advantages:

The system automatically closes (tightens) the insect net when we close the window and thus the appearance of the window and the building is not affected.

The automatic closing system increases the service life of the net - the net is not unnecessarily exposed to the action of sunlight and other meteorological phenomena at intervals when it is not needed, as are the currently known products.

It is not necessary to assemble, disassemble and store it during the winter.

The operator acts exclusively on the window handle, the automated net mechanism opens / unrolls the net and closes / runs it automatically.

Claims (1)

CLAIM Insect protection system consisting of a roller box, movable mesh and aluminum guides, characterized in that, in order to protect the interior of buildings, it is equipped with a rotary electric motor 7, powered by batteries or mains, whose shaft is supports on the supports 10 and drives in rotational motion the pulleys 11 on which the threads that wrap / open the insect net are wound, automatically, as a result of the control of a sensor fixed on the motor shaft that detects the position of the window (open / closed) and indicates in position 8 "DOWN" and in position 9 "UP", 8 and 9 being fixed on the outer casing of the roller.
