Field of application of the invention

The invention relates to a rail foot clamp for fastening one or more lines on the rail of rails for railway systems. It is used to attach cables in the rail foot of rails in stationary or retractable track systems.

Characteristic of the known state of the art There is a rail foot clamp for the attachment of pipes known in which the clamp the rail foot from below

comprises and between the reaching into the rail foot leg of the Cchienenfußklammer and the lines an additional, the number and the diameter of the lines adapted molding is inserted, via which the lines in the

Rail foot groove are kept. The disadvantages of this solution are that for the attachment of multiple lines

special, the respective diameter adapted moldings must be twisted and that in the removal or at

Replenishment of a line the Laye of the other line is impaired. It is also known a Schienenfußklammer for the attachment of heating elements for the points heating. At this Klammor the rail foot is also covered from below. The up to the rail foot throat roiehende leg of Rail foot clamp has a shape adapted to the diameter of the heating rod. This solution has the disadvantages that the attachment of two lines (rods) of the same diameter is not possible,

and that the fastening force on the respective diameter of the line (bending of the clip) is dependent. Also, in this solution, when removing or repositioning a line, the location of the remaining line is compromised.

In DE-OS 2132737 a device for attaching cables and lines is described in which a holding member on or

has several flexible sections that hold the cables in place.

The disadvantage of this solution is that the device is not the unique position of the lines even under axial load

ensures the lines.

Object of the invention

The object of the invention is to provide a Schienenfußklammer for securing lines to rails for railways, which is technically easy to manufacture and easy to mount on the rails without additional components.

Explanation of the essence of the invention

The invention has for its object to provide eino rail cam clamp for mounting cables in the rail foot of rails in stationary t the retractable track systems, with which it is possible to see several lines with the same or different diameter of a certain diameter range in a defined position attach and remove individual Loitungen or nachsetzen, without changing the position of the existing lines, with an electrical short circuit should be avoided.

According to the invention, the object is achieved in that the rail foot clamp from a clamp, preferably made of solid, resilient metal, and a clamp, preferably made of flexible metal, that the bracket has at least one reaching into the Schienonfußkehle legs, in the vicinity of the Rail foot groove is provided with an opening that

the clamp aufwoist a bridge, starting from the sides, starting from the middle, in each case alternate tabs, that the upwardly bent inner tabs are guided through the opening of the leg of the clip, that the web between rail and leg is arranged.

The tabs are partially radiused and bent approximately 90 degrees toward the railhead. The number of tabs corresponds in an advantageous embodiment of the invention of three times the number of lines to be fastened. The clamp and the clamp loosely connected with it are clamped to the rail foot below the railroad rail. The assembly is possible at any free point on the rail foot. After inserting and aligning the cables between the upright tabs of the Klemmo they are alternately bent and thus guarantee a firm position of the aligned lines.

A subsequent removal or refilling a second line without affecting the position of the first line is possible. The tabs of the clamp are arranged so that after bending no closed metallic ring (short circuit winding) is formed.

embodiment The invention will be explained in more detail below using an exemplary embodiment. In dor associated drawing show Fig. 1: the clamp with the centrally arranged, bent upwards tabs Fig. 2: the clip Fig. 3: the rail foot clamp with two firmly locked lines with different diameters. The Schienonfußklammer is divided into two parts and consists of a bracket 1, which ensures a firm hold on the rail and a foot Terminal 4, which is connected to the bracket 1 and with their bendable tabs 6 to 11 the solid, in a defined position

located seat of the lines 12,13 secures. To ensure a firm hold on the rail foot, the bracket is a solid springy metal.

At least one leg 3 includes the rail foot so far that it extends into the rail foot. It is in these Leg 3, approximately the distance of the smallest diameter of the lines 12 or 13, a slot introduced. The other Leg of the clip 1 may be formed so that it only partially covers the rail foot. The clamp 4 is preferably made of slightly flexible metal. It bestoht from a web 5, whose width is about the

smallest diameter of the lines 12,13 corresponds. On the longitudinal sides of the web 5, the tabs β to 11 are formed.

Here are located on one side of the web 5, the inner tabs 6,7 and, each offset to the outside, the middle Tabs 8,9, On the other side, the outer tabs 10,11 are arranged at the outer ends of the web. The location

the middle tabs 8,9 and the outer tabs 10,11 can also be changed.

The Laschon 6 to 11 are bent upwards. The diameter of the strongest line 12 or 13 is taken into account

and approximately formed. The middle tabs 6,7 are inserted through the slot 3, which is inserted in the leg 2 of the clip 1. Thus, the terminal 4 is clamped between rail and leg 2 during assembly.

Thereby, and by the width of the slot 3 and arrangement and the width of the Laschon 6.7 and 8.9, is also a safer Stop terminal 4 in clamp 1 reached. The rail foot clamp is pushed laterally at any free point below the rail on the Schiononfuß,

until the angled part of the clip snaps over the rail foot. Now each one needed

Lines 12 and / or 13, with the same or different diameter, inserted, aligned and by bending dor

respectively assigned tabs 6 to 11 (order dos bending: first the outer, then the inner) the

Lines 12,13 are set. Whether the cable with the larger Duichmesser front or behind is, can freely chosen

become. The rail foot clamp can also be used several times by repeatedly folding up and down the straps 6 to 11.

Claims (3)

1. rail foot clamp for attaching lines to the rail of rails for railways with stationary or retractable track systems, which includes the rail, characterized in that the rail foot clamp (1) from a rail foot from below embracing bracket (1) made of solid, resilient metal and a clamp (4) of flexible M & C held by the clip on the rail base, the clip (1) has at least one limb (2) extending into the foot of the foot which is provided with an opening (3) in the vicinity of the foot of the foot in that the clamp (4) has a web (5), from whose sides, starting from the middle, mutually flaps (6 to 12) depart, and in that the upwardly bent inner flaps (6, 7) thus pass through the opening (3) of the leg (2) of the clip (1) are guided, that the web (5) between the rail foot and leg (2) is arranged. 2. rail foot clamp according to claim 1, characterized in that the tabs (6 to 11), partially provided with a radius, are bent by approximately 90 degrees in the direction of the rail head. 3. rail foot clamp according to claim 1, characterized in that the number of tabs corresponds to three times the number of lines to be fastened.
