The invention will now be explained in more detail using schematic illustrations:

• In the 1 a cross section through the rail profile part 1 with the components attached to it, in particular comprising a sliding conductor 3, is shown.
• In the 2 an oblique view of such a rail section is shown.
• In the 3 an enlarged section of an antenna 8 of a vehicle is shown, which is guided by the rail and is arranged to be movable in the direction of the rail. The antenna 8 protrudes into a slotted waveguide profile.
• In the 4 another exemplary embodiment according to the invention is shown, with a line conductor 7 being provided instead of the contact line, so that the vehicle can be supplied without contact.
• In the 5 is an enlarged detail 4 shown.
• In the 6 a rail section is shown which has a curve.
• In the 7 is an enlarged detail 6 shown.
• In the 8th is an enlarged detail 1 shown.

Like in the 1 , 2 and in 8th shown, the rail profile part 1 has running areas for lateral guide wheels and a rolling area for a carrying wheel, with an undercut 10 being formed, into which a protruding nose area of a holding part 2 can be clipped.

The rail profile part 1 is preferably manufactured as an extruded part, in particular as an aluminum extruded part. Recesses can thus be provided in a simple manner in the rail profile part 1 if they extend in the direction of the rails.

The holding part 2 also has undercut areas so that further components can be clipped in. In particular, a first and a second further holding part 4 are provided for attaching barcode codes. A slotted waveguide profile can be clipped into a further undercut area of the holding part 2 .

This enables data to be transmitted from the vehicle that can be moved along the rail to a stationary device and vice versa.

As in 8th shown enlarged, the first further holding part 4 in the first clip connection area 81 and the second further holding part 4 in the second clip connection area 80 is clipped into an ent correspondingly shaped receptacle of the holding part 2. The first further holding part 4 is also inserted in a depression 82 and is thus held stably in two positions, with it being held in the intended orientation.

The clip connections of the slotted waveguide profile and the first and second further holding part 4 enable simple and quick production, since only one insertion is necessary.

As in 3 shown, the vehicle has an antenna 8 for this purpose and guides it along the slot, along the opening of the slot waveguide 5, during the movement of the vehicle along the rail formed by the rail profile parts 1 lined up in the rail direction.

In addition, a further undercut is formed on the holding part 2, which enables a sliding conductor 3 to be clipped in. The vehicle, in particular the drive motor of the vehicle, can thus be supplied with power by means of a contact line.

The holding part 2 is preferably made of plastic or a metal such as aluminum. The first and second additional holding part 4 is preferably made of plastic, with the barcode being printed on a print medium, such as plastic or paper, and being glued to the first and second additional holding part 4 .

As in the alternate embodiment shown in FIG 4 and 5 shown, the holding part 2 can be replaced by a different type of holding part 6 for a line conductor 7, in particular for a primary line, so that the vehicle can also be supplied without contact, in particular inductively. The vehicle has a secondary winding which can be inductively coupled to at least one of the line conductors 7 clipped into the different type of holding part 6. An alternating current can thus be impressed into the line conductor 7, in particular with a frequency between 10 kHz and 1000 kHz. A capacitance can be arranged on the vehicle in parallel and/or in series with the secondary winding, so that the associated resonant frequency of the resonant circuit formed in this way essentially corresponds to the frequency of the alternating current impressed on the line conductor 7 .

The different type of holding part 6 has a region that protrudes toward the vehicle, in which the line conductor 7, in particular a forward conductor of the current loop formed by the line conductor 7, can be accommodated. In addition, a region further away from the vehicle is provided on the different type of holding part 6, into which a return conductor of the current loop can be clipped. The field generated by the outgoing conductor can thus be guided at least partially through a U-shaped or C-shaped coil core of the secondary winding, and a high degree of efficiency can thus be achieved in the inductive energy transmission. The drive motor of the vehicle can be supplied from the secondary winding.

The different type of holding part 6 is preferably made of plastic or metal, such as aluminum.

As rail profile part 1 is in the embodiments according to 1 until 5 each use the same rail profile part.

On the vehicle is in both embodiments, so in the example 1 and 4 , Arranged a reader that reads the barcode, whereby a position determination of the vehicle is made possible within the rail system.

As in the 6 and 7 shown, the rail system also has curved sections, with no slotted waveguide 5 being arranged in the curved sections. Because the antenna 8 arranged on a vehicle having a front wheel spaced apart from the rear wheel in the rail direction would move out of the opening, ie out of the slot, of the slotted waveguide 5 in the curve section and thus prevent data transmission. Therefore, the slot waveguide 5 is saved in the area of the curved section.

Advantageously, the vehicle has two antennas 8, which are spaced apart from one another in the direction of the rails, the distance being large enough that when driving through the curved section, the region of the missing slot waveguide 5 can be bridged. The distance is therefore at least greater than the maximum secant length of that curve section in which no slotted waveguide 5 is laid. The distance is preferably even greater than the arc length of that curved section in which no slotted waveguide 5 is laid.

As in 1 shown, the rail profile part 1 has a T-shaped configuration on its upper side and on its underside. The roof of the upper T-shape forms the rolling surface for a rolling wheel on the vehicle. Guide wheels for lateral guidance roll on the lateral surfaces aligned perpendicularly to the roof. Below the roof of the undercut 10 is arranged, in which the holding part 2 engages.
