The present invention relates to an adjustable spacing element intended for alignment of structural details as frames, crossbars, casements, glasspanes and the like comprising at least two separate, cooperating parts having two, from each other directed outer support surfaces.

5 Today different types of wedges are usually used for alignment of structural details as frames, crossbars and the like. These wedges are bringing a number of inconveniences e.g.uneven load of the details supported in that moments are transmitted from the wedges when these have sloping support surfaces contacting the inclined detail. These strains in some instances can cause that the wedge losens or deforms the supported detail by spot 0 contacting so that said detail not remain in the desired, aligned position. Also two towards each other cooperating wedges are used for aligning of e.g. frames and crossbars, but here a problem arises in that after alignment the end parts of the wegdes often project beyond the limits of the frame, why an extra working moment in sawing off these projecting parts has to be done.

5 . The object of the present invention is to provide an adjustable spacing element of the type mentioned in the beginning, by which the drawbacks mentioned above are eliminated. The main characteristics for the present invention are stated in the following claims.

Thanks to the invention a spacing element has now been acheived which in a distinguished way fulfils its purposes at the same time as it is both cheep and easy to 0 make. Using the element according to the invention a totally strain free alignment of different structure details can be performed, by that the support surfaces of the element always are in parallelism independent of the hight adjusted position of the spacing element. By this parallelism of the support surfaces the aligned details are contacting the spacing elements totally strain free, no moments are created in the details and at the same 5 time as a very small surface pressure appears towards the aligned details in that the support elements have large support surfaces. An other advantage is that the spacing element according to the present invention can be mounted in a preset position before e.g. a frame is mounted and after the mounting there is a possibility for eventual after adjustments of the parts in the element by aid of a suitable tool.

As is illustrated in the figures and especially in Fig. 1 the adjustable spacing element, according to a preferred embodiment of the invention, consists of two separate, cooperating parts 1 and 2, which each comprises a supporting surface 3 and 4. These surfaces 3, 4 which are directed in a direction from each other, are adjustable towards and away from each other by turning of the cooperating parts 1, 2 relatively each other. The parts 1, 2 are provided to lie in contact with each other and comprise at least two, against neighbouring part 1 ; 2 correspondingly formed, cooperatable and in the height direction or thickness of the spacing element, continuosly obliquely inclined contact surfaces 5; 6 extending with a circular formed extension in the extension plane of the part 1; 2, said surfaces in turning of the parts 1, 2 of the spacing element relative each other move the supporting surfaces 3, 4 in a direction towards or away from each other during maintaining the parallelism of said surfaces. The obliquely inclined contact surfaces 5, 6 are stepped formed and consist of three on each part 1 and 2. Instead of making the the contact surfaces stepped formed these can be provided with rills or other suitable friction means in avoiding unintentional sliding between the surfaces. The contact surfaces 5, 6 also can be formed even if friction means are provided in connection to these. The contact surfaces 5, 6 have in the illustrated embodiment a circular extension in the extension plane of the parts 1, 2, a width in a radiel direction which is greater than the half radius of each part 1; 2 and an extension in the circumference direction of the parts 1; 2 being mainly 1/3

of the circumference of each part Recesses 7 are provided around the periphery of th lower part 2 and beyond the stepped formed contact surfaces 6, in said recesses at leas one projection 8, projecting from the upper part 1, is provided to cooperate when th stepped formed contact surfaces 5, 6 being in a perfect engagement with each other i.e rest with their surfaces completely against each other. Hereby is guaranteed that the part cooperate with each other using the greatest possible contact surface.

Each part 1, 2 is provided with a collar 9 and 10 in order to achieve a perfect guiding an at the same time a centering of the parts 1, 2. The collar 9 of the upper part has an oute diameter which is somewhat smaller than the inner diameter of the collar 10 of the lowe part 2, why the collar 9 is insertable into the collar 10. Each part 1; 2 is provided with bore 11, 12 in its centre which is intended to fix the parts of the spacing element i position both close to each other and to a frame by aid of a nail or screw not illustrated in the drawings.

The spacing element can of course also consist of two parts in the form of arc formed halves, put towards each other having contact surfaces of optional form. These contact surfaces provide in turning of the two parts relatively each other a variation of the distance between the two support surfaces of the spacing element

If the total height or thickness of the spacing element should not be enough in the case of larger alignment distances the spacing element can be completed with separate, against the same fixable spacers not illustrated in the drawing.
