Long stick for the blind

The innovation concerns a two-part, telescopic, infinitely adjustable, tubular long stick for the blind with one handle, a partially slotted clamping piece between the two parts and a probe tip.

The well-known white canes are very heavy and therefore soon lead to fatigue of the user and possibly to an inflammation in the forearm area. They usually consist of several parts that are plugged into one another and cannot be adjusted continuously. The tips commonly used on these sticks grind in usually within a few hours until it is unusable.

The innovation is based on the task of designing a white cane that is stable in any length and that is easy to commute slides well, the forearm strain is reduced to a minimum and has a wear-resistant end piece.

This object is achieved with the features listed in the claims for protection.

The innovation is explained using an exemplary embodiment.

The long stick shown in the figure consists essentially consisting of an upper tube 1, a lower tube 2, a probe tip 3 and a handle 4. The handle 4 is ergonomically shaped (it tapers towards the tip of the stick and is therefore suitable for different hand sizes suitable) and is provided with a flattening over the entire length for placing the index finger. The rear opening of the handle serves to remove the clamping piece; it is closed by the screw cap with cord 5.

The top tube is made of a high-strength aluminum alloy, which the down tube, which is also made of high-strength aluminum, takes up. At the lower end of the top tube, a reinforcing ring 6 prevents the Functional load leads to an increase in the diameter of the top tube. A plastic sleeve 7 allows the down tube to be frictionless and to guide in the top tube with little play.

The axial attachment of the two pipes to one another is achieved by a partial i
