Description

GERMAN

In known tonearms, a handle, a shoulder or a bracket is rigidly connected to the tonearm which the tonearm can be grasped to remove it from its support and onto the record put on. Finding the starting groove on the record depends to a large extent on the manual Skill of the operator.

Moved during the movement of the tonearm from the tonearm rest to the edge of the record the end of the tonearm is on a circle around the vertical tonearm axis. The hand and the wrist the operator must follow this movement and also a downward movement run to the grooves of the record. When it comes into contact with the record, it should move along with it great accuracy and sensitivity come to a standstill without the stylus of the pickup or damage the record itself. Operators to whom ^ the necessary manual Lack of skill; prepares the correct placement of the stylus on the record great Trouble.

An object of the present invention is to provide a phonograph tonearm that the operator can also use can operate without special skill and in which a hard touchdown of the stylus the record is avoided.

The invention consists in that the tonearm has an elastic and flexible handle.

It is already a tonearm with a around a horizontal, essentially in the longitudinal direction of the Tonearm horizontal axis pivoting handle known. This tonearm should also be used to find the starting groove on the record. In contrast to the present invention the handle serves not only to lift the tonearm to push out a support and towing device, with which the tonearm unrolls on the record from the inside out and which then the stylus is automatically placed on the record when the edge of the record is reached causes. This pivoting, but rigid handle would not be suitable in and of itself the characteristic of the elastic and flexible handle according to the present invention, the Put on the stylus to bring about a facilitating effect.

A tonearm is also known which can be pivoted essentially only in a horizontal plane, but cannot be raised and lowered. This tonearm also has the front part that carries the pickup provided with a rigid handle and connected to the actual tonearm via a leaf spring, via which he is elastic in a vertical plane and tonearm for record players

has been named as the inventor

is pivotable to ensure a secure support on the record and to put it on and to allow the stylus to lift off. The placement of this tonearm on the record prepares but the same difficulties as with an ordinary rigid handle Tonearm, as the actual tonearm cannot be swiveled around a horizontal axis.

Various embodiments of the invention are shown in the drawing.

Fig. 1 shows a tonearm in a perspective view;

FIGS. 2 to 6 show different embodiments of the handle and its attachment to the Tonearm.

On the tonearm 1 shown in Fig. 1, a handle 2, which is elastic, is arranged on the tonearm front part 1 a, in which the pickup is located. This handle preferably consists of a rod made of rubber or another elastic and flexible material; she can z. B. only consist of a piece of cord or a metallic spring, provided that they have sufficient flexibility.

The handle is attached to the upper surface of the tonearm front by known means, For example, it is inserted through a hole and has a node that it is in this Hole holds, or it is glued, it can also be rigidly connected or rotatably attached. If the tonearm is to be placed on the record, the rubber stick is placed between the thumb and forefinger held. The operator's hand now only needs a sideways movement to over to make the plate edge without taking it into account

Claims (10)

to have to take that the tonearm end describes a circular motion. The downward movement on the record is also elastic, because the handle is designed in such a way that the weight of the tonearm causes very little tension on the handle, which is released as soon as the stylus touches the record. An unfavorable guidance of the operator's hand therefore has no effect. The invention can be embodied in numerous embodiments. For example. the handle can be designed as an elastic and flexible spiral spring. It can also be other forms, such as. B. hooks or rings can be selected. 1S The handle can also be detachable and thus delivered as a replacement or to equip existing tonearms with it. In this latter case, the handle can have a larger surface 3 (FIGS. 2 and 3) with which the handle is glued to the tonearm. This surface can be coated beforehand with adhesive, which is protected against drying out by a suitable, impermeable plastic sheet until it is attached to the tonearm. The surface can also be attached to the tonearm front part by one or two rings or straps, which can be rigid or flexible or elastic. In Fig. 4, a handle is shown in which the fastening tape 4 consists of one piece with the handle, it can for example be cast from rubber or cut out. The embodiment shown in Fig. 5 differs from the previous embodiments in that the handle is connected to a spring clip 5 which comprises the tonearm front part. Fig. 6 shows a further embodiment with a metallic base 6 which elastically surrounds the edge of the tonearm. P χ TAX CALLS: 1.
