Claims

1. A window installation apparatus comprising a body (1), a clamp (3) and an expansion unit positioned between the body (1) and the clamp (3), wherein the expansion unit comprises a wedge (6) and a lead screw (9), wherein the clamp (3) comprises brackets (4), wherein the body (1) comprises lateral rails (5) and an opening (10) in a rest wall (11) against which a head of the lead screw (9) rests, wherein outer walls (7) of the wedge (6) and inner walls (8) of the body and the clamp (3) converge downward at a same angle, wherein the lead screw (9) is configured to drive into the wedge (6) to press the wedge (6) against the inner walls (8) of the body (1) and the clamp (3) thereby expanding the window installation apparatus, wherein the body (1) is slidably connected to the clamp (3), wherein the brackets (4) of the clamp (3) are disposed on the lateral rails of the body (1), and wherein the brackets (4) of the clamp (3) are configured to slide on the lateral rails (5), wherein the lead screw (9) is threadably connected to an opening (12) of the wedge (6), and wherein the body (1) has protrusions (2) positioned on opposite sides of the body (1) protruding in opposite directions, wherein the protrusions (2) lock the body (1) in a rail positioned outside of a window frame.

2. The window installation apparatus according to the claim 1, wherein an inclination angle of the inner walls (8) of the body (1) and the clamp (3) and the outer walls (7) of the wedge (6) is 10 to 50 degrees.

3. The window installation apparatus according to the claim 1, wherein the opening (10) in the rest wall (11) accommodating the lead screw (9) is elongated oval in shape.

4. The window installation apparatus according to the claim 1, wherein the inner walls (8) of the body (1) and the clamp (3) comprise vertical recesses (13) to accommodate the lead screw (9).

5. The window installation apparatus according to the claim 1, further comprising a cover (14) slidably connected to the clamp (3) such that the cover (14) is configured to slide with respect to clamp (3).

(8) FIG. 7 shows the clamp (bottom view),

(9) FIG. 8 shows a set of installation wedges (prior art),

(10) FIG. 9 shows a distance (expansion) piece (prior art),

(11) FIG. 10 shows a perspective view of an alignment kit (prior art), and

(12) FIG. 11 shows an exploded view of an alignment kit (prior art).

(13) The window installation apparatus according to the invention has been used for the installation of a PVC window. Four such devices were used.

(14) Each device was made of a plastic material technically known as POM (polyacetal), considered to be one of the most rigid and robust thermoplastics.

(15) The window installation apparatus comprises a body 1 intended for quick installation outside a PVC window frame (not shown in the drawing) near its corners by means of protrusions 2 extending from the body 1. The protrusions 2, positioned on opposite sides of the body 1, lock in a rail (not shown in the drawing) positioned outside the window frame.
The body 1 interacts with a clamp 3, connected in a sliding manner to the body 1 by means of brackets 4 of the clamp 3 and the rail 5 formed out of the sides of the body 1. Furthermore, the apparatus comprises an expansion unit consisting of a wedge 6 positioned between the body 1 and the clamp 3.
Outer walls 7 of the wedge 6 converge downwards at an angle of 30 degrees. Likewise, inner walls 8 of the body 1 and the movable clamp 3 (facing the wedge 6) incline at an angle of 30 degrees. Furthermore, the apparatus comprises a steel lead screw 9.
The lead screw 9 is positioned in the body 1, in an oval opening 10 made in a rest wall 11, against which its head rests from the bottom. The other end of the lead screw 9 is threaded into an opening 12 in the wedge 6.
Inner walls 8 of the body 1 and the clamp 3 comprise vertical recesses 13 to accommodate the screw 9.
Driving the lead screw 9 into the wedge 6 pulls the wedge 6 towards the body 1, as a result of which the walls 7 of the wedge 6 press against the inner walls 8 of the body 1 and the clamp 3. The interaction of the inclined elements 7 and 8 of the apparatus pushes the clamp 3 outwards, thus expanding the apparatus.
In the case of one of the four devices used according to the invention, the installer found that the expansion range was insufficient because the gap between the window and the wall was too wide. Therefore, he used an additional element in the form of a cover 14 for the clamp 3. The two elements are connected in a sliding manner by means of brackets 15 of the cover that mate with side rails 16 of the clamp 3.

(16) By using the devices according to the invention a single operator easily fitted and immobilized the window frame in a correct position in the window opening before its final installation by means of expanding foam.
