Abstract

The invention relates to a baton comprising at least two tube pieces, an outer tube piece and an inner tube piece which can be inserted into each other like a telescope and are interlockable in both the retracted and the deployed position. A radially displaceable locking top is disposed in the final region of the inner tube piece, which can be inserted into the outer tube piece, while a circumferential catching groove is arranged on the inside of the final region of the outer tube piece. The locking top is composed of several parts that are embodied like sectors of a circle and are joined so as to form a ring while the locking cap extends past the final region of the inner tube piece by means of a locking bulb. An expanding cone for the locking top is placed in side the inner tube piece across from the catching groove for the locking bulb, said expanding cone being movable to a limited extent in an axial direction and being fixed at the end of a positioning rod.

Description

The invention relates to a baton according to the preamble of patent claim 1.

Batons of this type are known in particular as police equipment according to EP 0 961 097 A2. What concerns the latchability of at least two pieces of pipe, this is done by means of built-in, spring-loaded Kugelverrastungen, which, seen radially, require a relatively large amount of space and thus a corresponding diameter measurement, d. h., Which can be pushed out of the tube piece forming the handle has a correspondingly small diameter, all the more so if such a baton for reasons of housing and portability consists of three telescopically telescoping pieces of pipe, which is the rule. This in turn means that the impact force in a correspondingly high impact pressure on the affected person and thus increases the risk of personal injury is increased. This is contrary to the actual purpose of batons per se, which should be more or less only a relatively harmless defense and threat weapon in police hands for the exercise of order tasks in, for example, sprawling demonstrations.

Starting from a baton of the type mentioned above, the invention has the object to dahingehnd such bats design and to the extent to improve that a total of fewer components required and in particular the recordable from the locking mechanism and transferable forces are greater. In addition, a further object of the invention is that the or the ausschiebbaren from the baton grip piece (e) with respect to the handle in spite of be accommodated therein latching elements only slightly reduced diameter, ie, the second or third shock-effective pipe section still has a comparatively large outer diameter has, associated with the proviso, thereby in a simple way to provide a targeted unlatching in order to push the baton back together.

This object is achieved with a baton of the type mentioned according to the invention by the features listed in the characterizing part of patent claim 1.

According to the invention, it is thus provided that the blocking crown is formed from a plurality of, preferably identical, circular sector-like (individual) parts joined together to form a ring, that the blocking crown projects beyond the end region or the upper end of the inner tube piece with a blocking bead, and that viscous A-vis to the Verrastungsnut for the blocking bead in the inner tube piece an axially limited adjustable, fixed at the end of an actuating rod expansion cone for the locking crown is arranged.

Decisive for the solution of the problem is therefore instead of a radial space claiming spring-loaded Kugelverrastung (with punctiform force receiving areas) the use of an annular, radially-adjustable, here called blocking crown (with area force receiving areas) of suitable material, such as cost, sliding and Also noise reasons preferably polyamide, which is dimensioned in relation to the available inner diameter of the baton tube pieces so that they rest in the installed state on the adjacent inner wall. The spreading or locking the locking crown takes place when "Ausschnicken" the push-out tube pieces simply by the impact of the locking crown on the one hand in itself stationary in the baton expansion cone, on the other hand, as will be explained in more detail, at the same time with slight axial adjustment for unlocking serves to push the baton together again.

Advantageous developments and embodiments consist in the following:

The so-called blocking crown here is a retaining bead with a diameter smaller than the blocking bead in a peripheral holding groove arranged fixed to the inner tube piece. It can be considered to use a suitable clamping ring within the locking crown, in the region of the radially outwardly pointing retaining bead. Specific embodiments thereof will be explained in more detail.

For the unlocking of the locking crown, the aforementioned control rod is advantageously connected to a spring-loaded pushbutton, which is arranged access-accessible in a screwed into the outer pipe piece closure piece for a finger pressure. This key operation can thus be done easily with the thumb of the baton holding hand, then with the other hand, the baton is simply pushed together.

Furthermore, the inner pipe piece on the discharge side, which will be explained in more detail, provided with a closure head which can be latched in an inserted position on a locking cone superior latching extension. Thus, the pushed together baton is also secured in this position in a simple manner.

An embodiment is preferred in that in the inner tube piece a further, correspondingly reduced diameter end tube piece is arranged with closure head, which is provided at its inner end with a correspondingly reduced diameter locking crown, which rests with its locking bead inside the inner tube piece, which is provided with a circumferential Verrastungsnut which, supported by one in the adjusting rod pushed out, the expansion cone by cross-bar, vis-a-vis is associated with a further expansion cone. Basically, this represents a repetition of the above-described two-part construction principle for the third pipe section with respect to the second pipe section, in which case the third pipe section still has a relatively large outer diameter.

In order to facilitate the expandability and retractability of the pipe sections of the baton and their guidance into each other, to prevent ingress of dirt, largely maintenance-free and even to provide noise reduction when mounting such a baton, are advantageously between the telescoping pieces of pipe in corresponding grooves grooves from this regard suitable plastic material (also preferably polyamide) arranged. In addition, in this connection, at least one air hole is arranged in the aforementioned, screwed into the outer tube closure piece for the purpose of pressure equalization.

The truncheon according to the invention is explained in more detail below with reference to the drawings of exemplary embodiments, specifically the preferred example of a three-part truncheon.

It shows

FIG. 1

on average the baton in the extended state;

FIG. 2

for reasons of clarity increases the baton of Figure 1 in the collapsed state. and

FIG. 3

Perspective and even further increases one of the locking crowns.

The baton consists of at least two telescopically telescoping pieces of pipe, namely an outer 1 and an inner pipe piece 2, which are locked together in both pushed together and extended position. Here, in the insertable into the outer tube piece 1 end portion 3 of the inner tube piece 2 is a radially adjustable locking crown 4 and inside the end portion 7 of the outer tube piece 1 a circumferential Verrastungsnut 8 is arranged.

Apart from the fact that a three-part baton is shown in Figures 1, 2, it is essential for the baton according to the invention that the locking crown 4 is formed of a plurality of (usually and preferably) identical, combined into a ring circular sector-like (single) parts in that the blocking crown 4 projects beyond the end region 3 of the inner tube piece 2 with a blocking bead 5, and that vis-a-vis to the latching groove 8 for the blocking bead 5 in the inner tube piece 2 axially for the purpose of unlocking limited adjustable, at the end of an actuating rod 10 fixed expansion cone 11 is arranged for the locking crown 4.

This, as shown in Figure 3, formed from a plurality of identical individual pieces locking crown 4 is arranged fixed with a blocking bead 5 smaller diameter retaining bead 6 in a circumferential retaining groove 12 of the inner pipe piece 2, wherein the fixing or holding voltage with an insertable clamping ring 27 made of suitable material is effected. With suitable plastic material may also be considered to form the locking crown 4 in one piece, in which case the necessary, axially oriented bead slits are provided offset above and below each other.

The control rod 10 is connected to a loaded with a spring 9 pushbutton 13, which is arranged access to a accessible in the outer tube piece 1 and cup-like closure member 14 access to the push button 13, as mentioned above, with the thumb of the baton holding hand for unlocking to depress the locking crown 4.

Furthermore, the inner pipe piece 2 on the output side is provided with a closure head 16 which can be latched in an inserted position on a spreading cone 11 projecting over the latching extension 17. Since a baton formed from only two pieces of tubing is not shown, one has to imagine the elimination of the elements with the reference numerals 19, 25 and 15 in Figure 1, this closure head 16 sitting directly at the free end of the pipe section 2, with respect to its analogous locking on Figure 2 to refer.

This figure 2 shows the preferred embodiment, according to which in the inner tube piece 2 another, correspondingly reduced diameter tail pipe piece 15 is arranged with closure head 16 and this is provided at its end portion 18 with a correspondingly reduced diameter locking crown 19. These locking crown 19 is located with its locking bead 23 inside the inner tube piece 2, which has a circumferential Verrastungsnut 24 which, supported by a pushed out in the control rod 10, the expansion cone 11 by cross-rod 26, vis-a-vis is associated with a further expansion cone 25.

The Verrastungsmechanik between the end pipe piece 15 and the inner pipe piece 2 thus corresponds essentially to that between the inner pipe piece 2 and outer pipe piece 1, wherein the unlatching is first effected and as described by pressure on the key 13, while the unlatching between inner pipe piece 2 and end pipe piece 15 through the aforementioned rod 26 is effected, which abuts when pushed together from below against the closure 14, which is provided for the purpose of pressure equalization with air holes 22.

Whether the baton consists of two or three pieces of pipe, so are advantageous for the reasons mentioned above between the telescoping pipe sections 1, 2; or 2, 15 arranged in corresponding grooves 20 slide rings 21.

The outer tube piece 1 is otherwise equipped with a non-slip coating 28 as usual.
