Description

The invention relates to a washer to compensate for bumps in assemblies, with a square body comprising a rectangle.

The invention further relates to a kit consisting of several such washers.

Washers are used in a variety of ways throughout the art. An important area for the use of washers is the compensation of surface irregularities on mounting surfaces to ensure a desired orientation of the part to be assembled. Thus, such washers z. B. used in the construction of precast concrete garages to compensate for unevenness in the surface of the Aufstellsockels, or when inserting window frames in a wall of a building o. Ä.

Usually, washers are usually made rectangular and formed in four sizes, which are designated by the information small, medium, larger and larger.

For each of these sizes of washers, however, a separate injection molding tool is required for the production, which is relatively expensive as well as the storage of different sizes of washers.

Here, the invention seeks to provide an improvement and suggest a shape for a washer, which allows to realize smaller, medium and large underlay surfaces, without requiring the use of different sized washers, which both the tooling costs for injection molding, as also keeps the storage costs of the washers low.

According to the invention, in the case of a washer of the type mentioned at the beginning, the plate body is provided on the outside of the rectangle with formations in the form of groove-shaped recesses and form projections, an equal number of shapes being provided and arranged in each case on two mutually opposite outer sides of the plate body. that each shaping on the one outer side according to their position on the opposite outer side is also assigned a respective shaping and two mutually associated shapes of a mold projection on an outer side and a groove-shaped recess on the opposite outer side (or vice versa), their shapes each other are designed positive-complementary.

The washer according to the invention now makes it possible to produce a multiplicity of sizes of shims by joining several such washers on its side walls, which makes it possible to make the washer according to the invention relatively small, since they are also assembled into large shims by being able to be assembled with other such shims can.

Due to the shaping according to the invention such that on each two opposite side surfaces of the washer of each indentation on one side on the opposite side in a corresponding position a shaping projection (or vice versa) is assigned, it is ensured that when mating two such washers on their respective sides also in each case a shaping projection is received on the one washer on the facing side of the other washer in a correspondingly form-fitting complementary shaped indentation. In this case, the formation of the shape of the mold projection means positive complementary to the shape of the indentation that in the assembled state, a positive retention of both washers is formed together.

As a result, the formation of a larger shim is made possible by mating a plurality of washers according to the invention to each other.

A particularly preferred embodiment of the washer according to the invention is that all groove-shaped indentations are formed on her in each case the same shape and all the form protrusions on her also in each case the same shape. As a result, it can be advantageously achieved that a particularly simple mating of several washers to form a larger shim and thus easy handling is provided.

In the washer according to the invention, it is quite possible to form only on one side of the plate body only indentations and on the other side only form protrusions. However, it is particularly preferable to provide the indentations and the form projections in alternating succession over the circumference of the plate body. This also makes it easy to connect multiple washers together.

The formation of the indentations and the form projections can be carried out in a washer according to the invention in many forms. However, it is particularly preferred and advantageous if the indentations and the form projections (seen in the clamping plane of the washer) each have a dovetail-shaped configuration by which a simple and also against unwanted opening positively locking connection is achieved when fastening two washers together. It is particularly advantageous if even the lateral boundary surfaces of the mold projections and the side surfaces of the groove-shaped indentations, each seen in the direction of the thickness of the plate body, complementary to each other are contra-conically inclined. As a result, when the washers according to the invention are fastened together, a particularly secure and firm shape holder of the same is achieved.

In addition, the invention also relates to a kit of such inventive washers, which all have a same shape and their plate body in arrangement next to each other on their sides facing each other with their formations mounted there form-fitting to form a larger Unterlegelementes are plugged together.

In the following description of the figures corresponding parts are always provided with the same reference numerals in the individual drawings.

The 1 to 3 refer to a washer 1 a first embodiment, which in 1 in an oblique perspective view, in 2 in a plan view and in 3 in a sectional view according to section line III - III in 2 is shown.

The washer 1 includes a plate body 2 which has a substantially rectangular shape.

The plate body 2 is on its four outer sides encircling with groove-shaped indentations 3 as well as with mold protrusions 4 provided around the outer periphery of the plate body 5 2 are formed around in alternating sequence.

Considering the shape of the individual groove-shaped formations 3 and the mold protrusions 4 , then these are shaped so that the shape of a projection 4 each form-fitting complementary to the shape of a groove-shaped recess 3 is executed, wherein in the embodiment shown here, the lateral boundary surfaces 6 and 7 every shape projection 4 , in the direction of the thickness D seen the washer, tapered to each other (see in particular sectional view III - III in 3 ). The side surfaces converge 6 and 7 every shape projection 4 and the side walls 8th and 9 each groove-shaped indentation 3 at an angle α (in the representation of 1 : downward).

The groove-shaped indentations 3 and the mold protrusions 4 have, respectively in parallel planes to the clamping plane of the washer 1 , a dovetail-shaped design, ie the side surfaces 6 and 7 the mold protrusions 4 are as well as the side surfaces 8th and 9 of the indentations 3 to the outer end surface of the relevant shaping projection 4 or to the groove base of the respective groove-shaped indentation 3 tilted, like this from the 1 to 3 in detail well, with the drawings being there expressly referred to.

The plate body 2 the washer 1 is formed substantially rectangular and thus has on its outer circumference two longitudinal sides 11 and 12 and two (shorter) transverse sides.

Looking at z. In 1 the one in the figure representation on top one outside (long side) 11 of the plate body 2 , then there is a shape advantage 4 between two groove-shaped depressions 3 educated.

On the opposite second outer side (longitudinal side) 12 of the plate body 2 Now, the position of each of the two wells 3 correspondingly opposite, two mold protrusions 4 formed, between which, the location of the molding protrusion 4 on the opposite long side 11 accordingly, a groove-shaped recess 3 is provided.

So if you have the opposite long sides 11 and 12 of the plate body 2 considered here, in principle applies here: Each shape advantage 4 on one of the two long sides 11 or 12 is on the opposite other long side 12 respectively. 11 at the same position a groove-shaped indentation 3 and each groove-shaped indentation 3 on one longitudinal side 11 or 12 is on the opposite longitudinal side of a molding projection 4 also assigned to the same position. In this case, all the form protrusions 4 with their side surfaces 6 and 7 and all groove-shaped depressions 3 with their side surfaces 8th and 9 at an angle α conically from top to bottom together, as can be seen from the 1 and 3 is removable.

The shape of the mold protrusions is 4 and the groove-shaped depressions 3 chosen so that the shape of each mold protrusion 4 positive-complementary compared to the shape of the associated groove-shaped recess 3 is trained. This results in that you have two juxtaposed such washers 1 such that the long side 11 one next to the long side 12 the other washer 1 lies, the mold protrusions 4 on the long side 12 one washer 1 in the groove-shaped indentations 3 on the long side 11 the next arranged another washer 1 can insert positive fit, at the same time the shape projection 4 on the long side 11 in the groove-shaped recess 3 on the long side 12 the other washer 1 enters positively.

In 4 is now one of the 1 corresponding perspective view of another embodiment for a washer 1 , in 5 a plan view of this and in 6 one of the sectional view in 3 corresponding section along cutting line V- V in 5 shown.

The difference in the design of the washer 1 in 4 opposite to the washer 1 out 1 is that the indentations 3 and the mold protrusions 4 here with their side surfaces 6 and 7 respectively. 8th and 9 not like at 1 , at an acute angle α tapered from top to bottom, but parallel to each other, as shown in the sectional view of 6 very clearly visible. However, here are the groove-shaped indentations 3 as well as the mold protrusions 4 , again in each case in parallel planes to the clamping plane of the washer 1 seen, formed with a dovetail shape design, as particularly well from the top view accordingly 5 is recognizable. This is also the case with two adjacent washers 1 such that the one longitudinal side 11 a washer next to the long side 12 the other washer is arranged and then each molding projection 4 on one longitudinal side of a washer in the correspondingly mounted indentation 3 is inserted on the longitudinal side of the other washer, a positive and parallel to the clamping plane of each of the two washers 1 non-releasable attachment of the washers to each other achieved.

In the 7 and 8th is now a kit of four washers 1 shown in perspective, wherein in 7 three washers 1 already attached to each other and the fourth washer 1 is lowered in the direction of the arrows F of (in the drawing) above. Here are the mold protrusions 4 in corresponding indentations 3 on the mutually facing outsides of two other washers 1 like this in 7 is shown, plugged in. In the process, the mold protrusions 4 on one of these other washers 1 in the assigned indentations 3 the washer to be lowered 1 inserted simultaneously positively, so that ultimately in the assembled state of this kit of washers 1 in the 8th shown end assembly is achieved in which the four washers 1 , which are attached to each other, together a larger shim 10 form.

The 9 and 10 correspond in principle to the representations of 7 and 8th , but with a kit 10 of four washers 1 according to the design 1 ,

For the production of washers 1 the kit is only the use of an injection mold and for storage only the provision of a form of washers 1 necessary, which means a much more favorable cost aspect.
