The present invention relates to a pair of wedges for line-up and fixation of windows and doors, and moreover corresponding usage other places where wedges are used - in breweries, residences and in industry. The pair of wedges consists of two level reverse-aligned wedges, each with a high end and a low/flat end and where the low end of the first wedge is connected to the high end of the second wedge, and where a parallel displacement of the wedges up or down of their respective reverse- aligned sloping paths are adjusted to each other's angles, with reference to fixation and movement in the longitudinal direction. To be able to move the wedge in either upward or downward direction the wedges are connected by an interior long bolt with a thread and the end piece of the bolt is fastened in a nut. The construction has the benefit that the volume of the travelling passage becomes longer than what is known today. This means that the wedges can elevate objects higher than by equivalently known techniques. The invention also makes it possible to adjust the downward direction.

The position of elements for lifting or lowering can be manipulated by adjusting the screw/bolt.

When you want to raise the wedge and thereby force the material into the desired direction, prior art has the disadvantage that the parallel displacement of the two wedges is physically limited by the distance they can travel in their respective paths. The general horizontal placement of the path of the bolt in the pair of wedges counteracts an optimal parallel displacement - as the screw movement of the bolt goes in the horizontal direction while the path of the wedge is in an upward direction.

A solution to this problem has been sought. In the patent literature we can find examples of how each wedge entail a key way/channel that is in line with the sloping surface of the wedge. It has been realized that the sloped key way gives increased movement volume.

GB 428624 has a sloped key way. A bolt is retained in the key way in one end of the wedge. The key way in the second wedge is designed with a thread that goes into gear with the thread of the bolt. The placement of the thread in the middle of the key way is a permanent arrangement and a crucial difference in the present invention.

EP 0080744 is of a different material and is intended to lift heavy elements. The construction shows a pair of wedges that create a rectangular square.

The extent of movement in wedges in connection to lifting or depression of elements such as doors or windows can be substantially optimized by the design form which is built-in to the present invention. The extent of the outermost optimization for both wedges is naturally where the wedges exceed the physical point of contact in the longitudinal direction. The closer you get to this limit the higher the collective height of the wedges.

The invention can be described in the following manner:

A pair of wedges comprising a first wedge and a second wedge, where each wedge consists of a sloping surface between a high end piece and a low/flat end piece, a keyway that is flush with the sloping surface of the wedge and stretches through the complete length of the wedge, where the wedges in the pair of wedges are placed complimentary with the sloping surfaces against each other, so the pair of wedges that creates a rectangular square and the keyways create a cavity in the length of the wedge and where a bolt placed in the keyway is fastened in the high end piece of the first wedge and goes into gear with a nut fastened in the keyway in the second wedge in the opposite end of the fastening point of the bolt in the first wedge and that the bolt can be screwed on by the assistance of a screwdriver where the nut is placed in the keyway close to the high end piece of the second wedge.

The embodiments vary with different options for positioning of thread/nut, from outer edge to the centre of the pair of wedges so that the movement longitude can be adjusted in either an upward or downward longitudinal direction.

Example of how it is possible technically to construct an alternative positioning of the nut:

In one embodiment it is equipped with a rail (10) in the keyway with a freely selected distance to each other and adaptive notches in the nut

(11).

The nut is thus placed freely on this rail and can thereby be moved to the selected and adapted notches in the nut, where from the nut can be released and glide/pushed onwards to a differently selected fastening. This design precisely implies the crucial difference to the prior art by the fact that the wedge does not have the same limitation in the freedom of movement. The movement between the wedge and the bolt is in accordance with each other and the limitation only consists in the length of the bolt as well as the naturally physical limitation in the respective reverse-aligned end pieces. By optimal tension of the bolt, the pair of wedges achieve the optimal height and have the physically minimal achievable contact with each other without running the risk of overloading the stability.

If an optimal elevation is desired, the distance of the nut to the highest end piece of the wedge shall be short; and in the case of a longer distance from the end piece an advantage can be obtained by extending the movement in depression. Free selection of placement of nut is established by assistance of a rail which the nut is in gear with.

The nut is locked in notches milled in the rail in pre-selected positions. Moreover, threading can be simplified by using a screwdriver and ensuring that the head of the bolt is designed for the bit on the screwdriver.

The wedges have along the sloping surfaces long side edges designed with excisions/milling adjusted to each other so that the long side of the first wedge is designed with two narrow level paths with bevelled angled insides that fit to the same excisions/millings on the second wedge.

Detailed description of the invention

Figure 1- The pair of wedges comprises a first wedge (2) and a second wedge (3). At the end of the pair of wedges the head of the bolt/screw (5) is visible. The cutting/milling fastening (8) is seen. Fig. 2 also shows the bolt (5) and the key way (4) designed for placement of bolt (5) and here the bevelled angle of the key way can easily be seen. On fig. 3 the section of the pair of wedges (1) are zoomed in - that is, where the bolt (5) is fastened to the first wedge (2).

On fig. 4 both wedges (2,3) are seen separated - flat in extension of each other. In the second wedge (3) a nut (6) is fastened. On fig. 5 both wedges are seen separated - with attention to the keyway (4). On fig. 5 both wedges (2,3) are seen separated and on fig. 8 it is zoomed in to the section of the bolt head (5) so that it is clearly seen that this is an example of a machine screw - so that the bolt (5) is designed and intended to be fastened with a screwdriver. Figure 6 shows the same section placed on the front of the pair of wedges (1) in the first wedge (2).

Collectively fig. 6 and fig. 7 also illustrate the cutting/milling fastening (8), respectively from front - fig. 6 and from the opposite end fig. 7. In figure 9 the pair of wedges are parallel displaced from each other in an upward direction and correspondingly on fig. 10 - here in downward direction. Moreover, the plate (7) for fastening of the screw and the same plate (7) with a hole for the bolt - in other words, it is in the wedge (2) that the bolt (5) is fastened..
