Description

Dr.-Ing. Hans Wüstl, Bubenreuth ü / Erl. , Waldstrasse 41 - .-. "Bridge for string instruments" \:

The invention "relates to a bridge for stringed instruments, "where the support points - for the strings in whose direction can be adjusted.

Such webs allow, in deviation from Bridges with fixed strings extend the length of the individual strings within certain limits "or to zoom out as it is for fine tuning of the instrument is required.

In known webs of this type, the adjustability is achieved in that each. Strings up one at a time small, movable on the bridge body in the direction of the strings Block rests when in the block toe small screws are screwed in, which in turn can be rotated at the rear. ,, raised edge of the bar body: are stored. When turning these screws, e.g. with a small screwdriver, the '

Blocks inevitably "moved in the longitudinal direction of the strings."

In another known embodiment: the blocks are adjusted by hand after the Blocks have been relieved a little by lifting the strings. With such bars, precautions must be taken that the loose blocks cannot fall out when the strings suddenly break. For this purpose, the blocks are moved in special guides. For example, in the bar body dovetail hats incorporated into which the blocks are inserted with their correspondingly designed lower end. Such Bar constructions have a complicated structure and require a correspondingly large amount of effort of manufacturing. In addition, the blocks if they are accidentally moved a little too far, slide out of the guides and fall off.

In the case of the bridge according to the present invention, these are Avoid disadvantages. The web body has a flat support surface for the individual blocks. Tucks is assigned a laterally leading, their movement path limiting, they secure upward holder .

This inventive proposal is preferably implemented in such a way that all brackets form a cage are summarized. The cage is put over the blocks by oloen and attached to the bar body ".

The cage advantageously consists of a frame with transverse strips which guide the side and take over the backup upwards, and with an upright edge that limits the path of movement ".

The drawing illustrates an exemplary embodiment in a schematic representation. Here show:

Jig. 1 shows a web according to the invention in cross section;

Jig. 2 the same web in longitudinal section; I ¹ Ig. 3 the same cut on another

■ * embodiment and
I ¹ Xg. 4 the frame, graphically.

The web consists of the web body 1 on the Body 2 of the instrument is attached. On the Bridge body 1, the blocks 3 rest, which are provided with notches 5 to accommodate the strings 4.

All blocks 3 have a cage in common, which, as already mentioned, they move when they move

leads laterally, "limits their movement path and secures them against falling out upwards. This cage" consists of the frame 6, which is provided with the transverse strips 7, which take over the lateral guidance of the blocks 3. These have a widened foot W with which they grip under the guide bar 7. In this way they are secured against falling out upwards. The frame 6 loads

between
sits two / the strips 7 raised longitudinal edges 8,

which limit the sliding movement of the blocks.

It is clear that instead of the widened foot part 10 of the blocks, another cross member is provided can be, e.g. a transverse pin 9> as shown in FIG.

In order to ensure easy adjustability of the blocks, it must be between the block and the edges the recesses in the cage be a little game. But this can under certain conditions, e.g. when the instrument is played with a vibrating device and electro-acoustic sound reproduction will lead to unpleasant noises. Therefore, it is provided according to the invention, the blocks made of non-metallic material, e.g. plastic.

furthermore it has proven to be advantageous that Roughen the surface of the blocks with which they sit on the bridge body. With plastic blocks this rough surface can be created with the injection molding process.

Claims (8)

Protection claims 1. Bridge for stringed instruments with in the direction of the strings adjustable string rest, with the string rest on a bridge body attached to the instrument forming blocks are displaceable, characterized in that one for the blocks they laterally leading, their path of movement limiting and they are provided upwardly securing bracket is. 2. bridge for stringed instruments according to claim 1, characterized marked that all Halteiuigen all blocks are combined into a cage. 3.
