Bar handle for disabled people

The subject of the present innovation is a handle for disabled people according to the generic term of protection claim 1.

Such a bow handle is known, for example, from the older DE 90 16 827 U. There, a swivel device is described with which it is possible to swivel the bow handle relative to a stationary plate.

The handle should be designed to lock itself in any swivel position.

A so-called sleeve freewheel is proposed here, in which the swivel movement takes place in one direction without any significant effort, while a blocking takes place in the opposite direction .

However, with this known arrangement it is difficult to swing back from a position that has been swung up to a basic position, because a clamping sleeve must be actuated with relatively high force for this purpose/3, and when this is swung, a high degree of

wear and tear occurs.

The present innovation is therefore based on the task of further developing a bow handle of the type mentioned at the beginning so that it can be swiveled into any swivel position easily and reliably and that it can also be swiveled back without significant expenditure of force and without significant wear.

The innovation is based on the further task of making the disabled handle as ergonomic as possible.

To solve the problem posed, the innovation is characterized by the technical teaching of claim 1.

Features of the innovation are that/3 the handle essentially consists of two arms which are connected to one another at their front end and which are arranged offset from one another in the vertical direction, the arms being accommodated in a holder, which holder is accommodated on a stationary plate so as to be pivotable about a horizontal axis, and that/3 the pivoting between the arms and the stationary plate takes place under the influence of a spring-loaded slip clutch.

The technical teaching provided provides the essential advantage that a relatively simple to construct bow handle is now proposed, which is essentially U-shaped and whose two U-arms are connected to one another at their front end. It is expedient to arrange the two arms offset from one another in the vertical direction in order to

Hand to be able to grasp the lower arm from above, with the user's forearm resting on the upper arm.

It is advantageous to use such a U-shaped handle because by simply changing the shape the handle can be used as a left or right handle, whereas the prior art proposes a construction with three arms that cannot be used as a left or right handle, which means that it is necessary to produce both a left and a right handle, which entails considerable manufacturing effort.

It is also preferred if the slip clutch acts on both sides of the wall-side plate in order to ensure a favorable force transmission.

0 In this case, it is also preferred that the slip clutch is adjustable and that a threaded bushing is provided for this purpose, which can be screwed more or less tightly into an associated threaded hole in order to change the pressure force on a friction disk or a disc spring.

Once the threaded bushing has been screwed in, it is then fixed using a clamping screw.

The subject matter of the present innovation arises not only from the subject matter of the individual protection claims, but also from the combination of the individual protection claims with one another.

All information contained in the documents, including the summary,

The information and features disclosed, in particular the spatial configuration shown in the drawings, are claimed as essential to the invention insofar as they are new compared to the prior art, individually or in combination.

In the following, the innovation is explained in more detail using drawings showing several implementation options. The drawings and their descriptions reveal further key features and advantages of the innovation.

Figure 2: Section through the slip clutch;

Figure 3: Top view of the handle in the direction of arrow III in Figure 1;

Figure 4: Side view of the complete bow handle; Figure 5: Top view of the complete bow handle.

The bow handle 1 essentially consists of two arms 2,3, which are arranged vertically one above the other at an angle to one another and are connected to one another at their 0 front free ends. The rear free ends of the arms 2,3 are received in a holder 4, which is made of plastic or metal.

5 In addition to the displacement of the arms 2,3 in the vertical direction

one above the other (compare Figure 5), the arms can also be arranged directly above one another in a vertical direction in a plane.

In the holder 4, an upper tubular receptacle 5 for the rear end of the arm 2 is arranged and the rear end of the arm 3 is received in a receptacle 6 located underneath.

The lower mount 6 is adjustable in order to make the angle of inclination of the arms 2,3 adjustable in the direction of the horizontal.

For this purpose, according to Figure 1, the holder-side end of the arm 3 is designed as a threaded tube 17, into which a threaded bush 18 can be adjusted and which rests with its rear end on a stop surface 19 on a wall plate 7.

0 The angle position of the arm 3 in the direction of the horizontal is adjusted according to the screwing depth of the threaded bush 18 into the threaded tube 17.

The entire holder 4 is pivotably mounted on the pivot axis 8 on the wall plate 7 which is to be attached to a wall.

For this purpose, a shaft 9 is provided which passes through the head 10 of the wall plate 7, whereby between 0 the head 10 of the wall plate 7 and the associated holder 5 an approximately U-shaped recess 11 is formed, through which the shaft 9 passes.

To adjust the swivel movement, 10 slip clutches are located on both sides of the head

22, which are explained in more detail with reference to Figure 2.

Here, it is provided that a threaded hole 12 is arranged in the holder 5, into which a threaded bush

13 is screwed in. The inner end of the threaded bush 13 acts on a spring washer

14 or on a disc spring, which in turn is supported on the front side of the head 10 of the wall plate 7.

Depending on how the threaded bushing 13 is screwed into the threaded hole 12, the force on the spring washer 14 is adjusted. Once the setting position has been found, it is then fixed with the clamping screw 15.

On the opposite side, a similar slip clutch is formed, as shown in Figure 3.

With the slip clutch provided, it is therefore very easy to set a selected swivel position around the swivel axis 8, which occurs both in the raised position and in the swiveled down position with relatively equal swivel force.

In the embodiment shown, the two arms 2, 3 are offset from one another in the horizontal direction and a connecting arm 20 is provided which enables a lateral offset of the upper arm 2 to the lower arm 3, whereby a through opening 21 is created between the two arms.

This increases the width of the handlebar so that better support is possible.

With this innovation, it is possible to swivel a handle into any desired position, and swivel it back without significant effort or wear.
