CLAIMS

1. A device (1) for releasing glasses (2) from the bodies (3) of vehicles comprising a frame (4) fitted with at least one suction pad (5) for detachable fastening to the glass (2) being released, at least one guide pulley (6) equipped with at least one guide groove (7) to guide a cutting wire (8), at least one winding pulley (9) fitted with at least one winding groove (10) to wind the cutting wire (8), characterized in that the frame (4) is fitted with two winding pulleys (9) and one guide pulley (6) equipped with two guide grooves (7), or the frame (4) is fitted with two winding pulleys (9) and two guide pulleys (6) each with one guide groove (7) and with a common central line, where the pulleys (6, 9) are arranged on the frame (4) in a manner that their central lines intersect the apices of a triangle, wherein the distance (L) between the central lines of the winding pulleys (9) is greater or equals the diameter (D) of the circle circumscribed on the projection of the suction pad (5), and the value of the altitude (V) of the triangle from the apex intersected by the central line of the guide pulley (6) is greater or equals the diameter (D) of the circle circumscribed on the projection of the suction pad (5), and the winding pulleys (9) are fitted with at least one spacing element for guiding the cutting wire (8) outside the suction pad (5).

2. The device according to claim 1, characterized in that the spacing element for guiding the cutting wire (8) of the winding pulley (9) comprises a spacing pulley (11) fitted with a guide groove (7), wherein the winding pulley (9) and the spacing pulley (11) have a common shaft (12).

3. The device according to claim 1 or 2, characterized in that the winding pulleys (9) and/or spacing pulleys (11) are fitted with a single-thrust bearing.

4. The device according to any of claims 1 to 3, characterized in that the guide grooves (7) and/or winding grooves (10) are fitted with a cone-shaped leading edge (13) on one side for a cutting wire (8).

5. The device according to any of claims 1 to 4, characterized in that the winding pulleys (9) are fitted with an adapter (14) for mounting a socket wrench, crank handle or electric motor.

1

6. The device according to any of claims 1 to 5, characterized in that the frame (4) is equipped with a handle (16).

7. The device according to claim 6, characterized in that that handle (16) includes an integrated pump connected to the suction pad (5) and/or a control valve connected to the suction pad (5) to control the vacuum.

8. The device according to claim 7, characterized in that the frame (4) is substantially planar with top and bottom sides, wherein the suction pads (5), guide pulley (6), and the spacing element are arranged at the bottom side of the frame (4), whereas the winding pulleys (9) and handle (16) are arranged at the top side of the frame (4).

9. The method of releasing glasses (2) from the bodies (3) of vehicles using the device (1) designed according to any of patent claims 1 through 8 where the device (1) includes at least one suction pad (5), guide pulley (6) fitted with two guide grooves (7) to guide the cutting wire (8) or two guide pulleys (6) with a designated guide groove (7) and a common central line, two winding pulleys (9) equipped with winding grooves (10) for winding the cutting wire (8), and a spacing element or a spacing pulley (11), characterized in that it includes the following procedure steps:

a) fastening the device (1) to the glass (2) using the suction pad (5),

b) arranging the cutting wire (8) along the circumference of the glass (2) on the side that is opposite to the side on which the device (1) has been fastened and pulling through the cutting wire (8) free ends between the glass (2) and the body (3) of the vehicle to the side of the glass (2) with the fastened device (1),

c) fastening the free ends of the cutting wire (8) to the winding pulleys (9) wherein each end of the cutting wire (8) is led around the spacing elements or in the guide grooves (7) of the spacing pulleys (11) and then each end of the cutting wire (8) is led in a designated guide groove (7) of the guide pulley (6) and the free ends of the cutting wire (8) are fastened into the winding grooves (10) of the winding pulleys (9), d) winding the cutting wire (8) onto the winding pulleys (9) either successively or simultaneously until complete winding up the cutting wire (8) onto the winding pulleys

2 (9) whereby the cutting wire (8) is cutting through between the glass (2) and the vehicle body (3),

removing the device (1) from the released glass (2).
