Description

Technical area

The invention relates to a kit for producing a linear measuring device, which has at least one linear scale body, in particular a magnetic tape, which is arranged on a support.

State of the art

Such kits for linear measuring devices are already known in many forms and designs on the market and in use. So shows, for example, the EP 1 047 085 A2 a longitudinally extending element in which a magnetic material is applied and / or applied in or on a base body. This magnetic material forms a linear measuring system in combination with a sensor or encoder.

Most carrier units for magnetic tapes are made of one piece and in fixed profile lengths, so that, for example, the transport is often associated with high costs. The storage of such units is very expensive, since a lot of space is needed.

The DE 102 015 102 322 A1 shows a linear measuring device according to the invention, which consists primarily of a magnetic element in the form of a flexible magnetic tape and a metal support member in the form of a carrier tape made of steel. In this case, other metal materials come into consideration. Steel is suitable in a special way. Steel provides the necessary mechanical stability and determines the extent of the linear measuring device with its coefficient of expansion.

Object of the invention

The present invention is based on the object to show a linear measuring device, of lightweight design and construction is to make the whole system more advantageous for transport and storage.

Solution of the task

To achieve the object result that the carrier is made of a base profile and a scale profile.

Furthermore, the base profile and the scale profile should be releasably connected to each other. With this feature and the at least two parts of the carrier, a lightweight construction is guaranteed. The profiles are intended, in the preferred embodiment, to be made of a lightweight material, e.g. Be made of aluminum to reduce the weight of the device significantly.

The base profile and the scale profile show a sliding guide, which in the preferred embodiment is a dovetail guide, one profile having an undercut groove and the other profile having a dovetailed cross-sectional shaped strip which fits into the groove. Thus, the carrier is easily disassembled and needed as a further advantage no fasteners or holes.

It should also form a plurality of base profiles and scale profiles the support for the scale body. The idea is to obtain a mounting base for the scale body with short, standardized individual profiles by arbitrarily juxtaposing the individual profiles.

Thus, the carrier can be divided into several individual pieces and different lengths can be built. The advantage here is that both built different carrier lengths, and the transport and storage costs are reduced, since the transport and storage of smaller parts is easier and less expensive.

Both the base profile and the scale profile preferably have the same lengths but are offset with each other. The same lengths mean that the components can, for example, share a package and thus avoid the cost of other sizes of the package. The staggered construction of the base rail and the magnetic tape rail is to bring about the same stability and side orientation as that in a manufactured component, e.g. made of steel is the case.

In order to achieve the offset structure, a base profile or a scale profile of half the length of the other profiles is arranged at each end of the carrier. This ensures easy handling and makes the construction and the achievement of the fit very easy.

The carrier is bounded at least at one end by a mounting base in order to ensure good stability.

At least one base profile is associated with a base rail support to secure the carrier to or on a substrate. For larger lengths of the carrier can be connected through the insertion of multiple base rail pads the tread structure even firmer and safer with the ground.

The base rail support is further arranged displaceably along the base profile. This ensures the flexibility of attachment to the selected surface.

It should be noted that the scale body is inserted into a scale groove in the scale profile and in this case no further fasteners are needed or a special tool.

Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawings; these show in:

• 1 an exploded perspective view of a kit of a linear measuring device;
• 2 a perspective view of the kit according to 1 in assembled condition;
• 3 an enlarged view of a section of the kit according to 1 ,

In 1 is an exploded perspective view of a kit of a linear measuring device 1 represented, which at least one carrier 2 and a linear scale body 3 , in particular a magnetic tape.

The scale body 3 is in a scale groove 4 on the carrier 2 arranged, wherein the scale body 3 by two clip strips 5.1 and 5.2 on the carrier 2 is held.

The carrier 2 consists of a base profile 6 and a scale profile 7 , The basic profile 6 and the scale profile 7 are made in the preferred embodiment of aluminum, in a plurality and releasably connected to each other.

Both the basic profile 6 as well as the scale profile 7 have a sliding guide 8th on, in the preferred embodiment, the sliding guide 8th is a dovetail guide. This means that in this embodiment, the base profile 6 an undercut groove 9 and the scale profile 7 a dovetail-shaped strip in cross-section 10 which is in the groove 9 intervenes.

In addition, in 1 seen that the base profile 6 and the scale profile 7 have the same lengths a, but these are offset from each other with each other. This is possible because of the carrier 2 each at one end 11.1 and 11.2 either a basic profile 6 or a scale profile 7 having half the length b of the other profiles.

Further, the carrier has 3 at least at one end 11.1 or 11.2 a mounting base 12 on, which is provided as a limitation and attachment of the device.

The basic profile 6 optionally has at least one base rail support 13 on, which can be used as additional attachment for longer lengths on a not further listed subsoil. These are holes 14 in the base rail pad 13 brought in. In addition, it is displaceable along the base profile 6 arranged by giving yourself a nose 15 which is in a base groove 16 can be performed.

In 2 becomes the kit of a linear measuring device 1 shown in assembled condition, here very clearly the staggered arrangement of the base profile 6 and the scale profile 7 is shown.

According to 3 a section of the kit is shown. Here is good the dovetail sliding guide 8th and thus the groove 9 in the base profile 6 to recognize, in which the strip 10 of the scale profile 7 intervenes.

Also, the scale body 2 shown enlarged, in the scale groove 4 lies and from the clip strips 5.1 and 5.2 on the carrier 2 is held.
