Magnetic blocade for window or wing

Abstract

 The subject of the invention is magnetic blockade for plastic window sash which has permanent magnets (11) placed in rotating arms (5) and (6). The permanent magnets are moving over plates (12), (13) and (16). which are placed on both sides of those permanent magnets. In addition it has slider (19) and steel strip (17). The slider (19) can rotate over pin (9). The slider (19) with magnets (20) is surrounded by plastic cover (18). The steel strip (17) is attached to the grove of plastic window or plastic balcony door using screws(21).

Description

[0001] The purpose of this invention is to create blockade which allows to keep plastic window sash and plastic balcony door opened in any position.

[0002] An advantage of this invention is that setting up window sash's and balcony door's position is done smoothly. The blockade is not visible after closing window. It is located in the free space between sash and frame. The blockade is hermetic and durable.

[0003] The subject of the invention: "Magnetic blockade for plastic window sash and plastic balcony door" is visible on the following figures. Figure no. 1. shows top basic view of blockade for a small plastic window Figure no. 2. shows side right view. Figure no. 3. shows top basic view of blockade for a plastic balcony door or a big plastic window. Figure no 4. shows a main side view.

[0004] The blockade, according to the invention, contains solid basis (1), which has two ledges (2) used for additional protection of the solid basis (1) against any rotation after placing them into groove of plastic window's frame. The solid basis (1) is attached to plastic window's frame using screws (3). The rotating lever is attached to the solid basis (1) with a rivet (4). The rotating lever is build up from two arms (5) and (6) which are separated by a strip (7) and fixed by rivets (8). On one end of rotating lever its arms (5) and (6) have circle shape with through holes. Permanent magnets (11) are placed inside that through holes. The arm (5) with magnets (11) is placed on a fixed bottom plate (16). The arms (5) and (6) are separated by a fixed middle plate (12). From the top the arm (6) with magnets (11) is covered by a top plate (13). The solid basis (1) is connected with the bottom plate (16), with the the middle plate (12) and with the top plate (13) by rivets (14) placed in sleeves (15). The blocking effect is achieved by rotating connected arms (5) and (6) together with moving magnets (11) between solid plates (16), (12) and (13).

[0005] There is a pin (9) surrounded by a muff (10) on the other end of the rotating lever. The pin (9) and the muff (10) are placed in groove of plastic window sash. They are used to place the sash in any position.

[0006] A rotating slider (19) is used instead of pin (9) and muff (10) to block the plastic balcony door or big plastic window sash. Magnets (20) are placed on top side of slider (19). The slider (19) with magnets (20) is surrounded by plastic cover (18). Containing magnets (20) top side of the slider (19) touches steel strip (17) which is attached to groove of plastic window sash or plastic balcony door using screws (21). The pin (9) which is put inside groove of plastic window sash or plastic balcony door, together with slider (19) are used to make stronger blocking in any position.

Claims
