Walking stick

The invention relates to a walking stick with a shaft and a handle, wherein a tear gas cartridge that can be activated by the user is integrated in the stick.

Such walking sticks are known from the state of the art, for example from DE-OS 38 08 362 and DE-OS 31 11 908.

The first-mentioned publication describes a multi-purpose baton in which a cartridge containing irritant gas can be arranged in one end of the shaft.

From the second publication, a baton is known in which a tear gas cartridge is also housed in the shaft, but which is connected to the outside world via a side outlet opening for the tear gas to be sprayed.

With both of the above-mentioned walking sticks, the tear gas trigger can only be activated by using the second hand, since the triggers are located so far away from the handle that they cannot be activated by the hand resting on the handle.

In addition, the aiming effect of both sticks is poor, with the user having to fend off an attacker with his defensive reaction

This cannot be a surprise, as various precautions must first be taken to prepare the stick for defense.

Another disadvantage of these previously known sticks is

that the tear gas cartridge in the shaft of the stick

is housed, a multi-part design of this shaft is necessary.

Since such a stick consists of several parts that can be detachably connected to one another, the stability of such a stick is not particularly great.

The invention is therefore based on the object of designing a walking stick of the type mentioned at the beginning, the defense mechanism of which can be operated very easily with one hand, can be handled accurately and at the same time has a stable design.

The invention solves this problem according to the characterizing part of claim 1 in that the stick is T-shaped, the handle forming the horizontal T-piece is a straight piece of pipe and forms the receptacle for the tear gas cartridge, the longitudinal axis of the handle running transversely to the longitudinal axis of the shaft, an opening for the tear gas to escape is provided in one end of the handle and a mechanical device for opening the tear gas cartridge valve is provided on the handle.

This design, in which the target is automatically aimed at in the event of a sudden attack by rotating the stick around its longitudinal axis and the device for opening the tear gas cartridge valve is ergonomically arranged on the handle, allows an immediate defensive reaction without the attacker being warned by preparatory actions on the part of the stick user.

According to claim 2, the opening for the exit of the tear gas is arranged in a lid that can be screwed on/off at the end of the handle.

The lid serves simultaneously as a holder and stop for the valve of the tear gas cartridge, where the opening of the valve is caused by the relative movement of the valve housing and the container.

The outlet opening for the gas can also be located in the front wall of the handle tube. In this case, the end of the handle opposite the opening can be closed with a screw-on/screw-on cover.

According to the embodiment according to claim 4, the mechanical device for opening the cartridge valve consists of a lever pivotably mounted in the handle wall, the end of which extends into the handle tube and can be pressed against the end of the cartridge facing away from the valve of the cartridge. By operating the lever, the cartridge container is pushed against the valve housing, whereby the valve opens. By releasing the lever, the container returns to its original position and the valve closes.

An alternative to the embodiment according to claim 4 is proposed in claim 5.

The mechanical device for opening the cartridge valve consists of a wedge-shaped bolt which is slidably mounted in the handle wall, the bevelled wedge surface of which rests against the front side of the cartridge facing away from the valve of the cartridge and the other end of which protrudes beyond the handle surface.

By pushing down the bolt, the wedge moves the cartridge container forward relative to the valve housing, which

Valve opens. By releasing the bolt, the container returns to its original position and the valve closes.

In order to prevent unintentional actuation of the valve, the invention according to claim 6 provides that the mechanical device for opening the cartridge valve can be locked by a safety device.

This is achieved in a device according to claim 4, for example, by a bolt that can be inserted between the lever and the cartridge or by a sleeve that can be pushed onto the handle and rests against the outwardly projecting part of the lever.

In a device according to claim 5, such a safety device could consist of a split pin or pin which is pushed above the handle surface through a hole provided in the bolt.

The invention is described below using two embodiments.

Show it:

Fig. 1: Walking stick in broken representation in a first alternative,

Fig.2: Walking stick in a second alternative

In Fig. 1, a walking stick is shown in a broken-off view and is generally provided with the reference number 1.

It has a T-shaped construction, with the horizontal T-piece being formed by the handle 2, the longitudinal axis of which runs transversely to the longitudinal axis of the shaft 3.

The handle 2 consists of a piece of pipe 4 which is closed at the right end 5 in the drawing. The left end in the drawing is closed by a cover 6 which can be screwed onto the end of the pipe and which has a hole 7 in the middle.

In the handle 2 there is a commercially available tear gas cartridge 8, the valve 9 of which is arranged in a recess in the lid 6. The tear gas container can be moved relative to the valve housing, which causes the valve 9 to open or close.

At the end of the handle 2 facing away from the valve 9, between the rear face of the cartridge 8 and the rear wall 5 of the handle 2, there is a lever 10 pivotably mounted in the handle wall, one end 11 of which projects outwards. By pivoting this lever end 11 in the direction of arrow a, the cartridge container is displaced in the direction of the opening 7, whereby the valve 9 is opened and the tear gas exits through the hole 7.

To secure the lever 10 against unintentional actuation, a pin 12 is inserted through the handle wall and pushed in front of the inner end of the lever 10.

In Fig. 2, the same elements as in Fig. 1 are provided with the same reference numerals.

In contrast to the embodiment according to Fig. 1, here the device for opening the cartridge valve 9 consists of a bolt 13 which is slidably mounted in the handle wall and which has a cylindrical region 14 protruding above the handle surface and a wedge-shaped region 15 protruding into the interior of the handle 2. The beveled surface of the wedge-shaped region 15 rests against the end face of the cartridge 8 facing away from the valve 9.

By pressing down the bolt 13, the cartridge container is pushed towards the cover 6 and the valve 9 is opened. By releasing the bolt 13, the

Cartridge container spring-supported into its starting position, and the bolt 13 moves upwards.

In order to prevent the bolt 13 from falling out or from being inserted too deeply, the bolt 13 has an upper stop 16 and a stop 17 arranged below the handle wall.

In the present embodiment, the bolt 13 is secured against unintentional actuation by a pin 18 which is inserted through a bore 19 provided in the cylindrical region 14 of the bolt 13.
