Abstract

The invention relates to a device for Schuszzahlerfassung, especially in sports rifles, by Zaehlwerk that can be applied to all bullets for recreational and Leistungsschieszsport. The apparatus is characterized in that a permanent magnet is mounted on a movable hammer, and that a magnetic sensor is further arranged so as to approximate the proximity of a permanent magnet caused by the hammer movement to a magnetic sensor connected to a digital display electronic counter of the type known per se. leads to a pulse-controlled shots.

Field of application of the invention

The invention relates to a device for determining the number of shots, especially in sports rifles, by means of electronic counter, which can be applied to all firearms for recreational and competitive shooting.

Characteristic of the known state of the art

Known are simple scaled Merkscheiben, which are set according to the delivered number of shots manually by the shooter on the weapon. They have the disadvantage of a subjective condition of the counting process.

Furthermore, according to DE-OS 1939816, DE-OS 1966150 and DE-PS 3120128, mechanical weft counters on compressed air guns which register the number of shots delivered via suitable lever or plunger movements of the trigger mechanism or of the pressure piston.

These shot meters are relatively bulky as components and use wearing mechanical counters. Their use requires special, costly design changes to the sporting weapon, the abrasion properties of the transmission elements in continuous operation lead to susceptibility to interference in the counting process.

Also become known electronic counters to the Schußzahlerfassung. In this case, the pulse is initiated by means of micro-switches, which are also operated by levers or plungers, which are arranged on the weapon. The disadvantage here is the necessary fixed line connection or wiring for transmitting the pulses to the counter.

Object of the invention

The aim of the invention is to provide the o.g. Disadvantages aut to eliminate the prior art. In particular, a counting device for Schußzahlerfassung to be created, which is coupled to the system of the sporting weapon neither mechanically nor via electrical signal lines. The pulse detection is done so that only actually delivered shots are counted and no energetic load on the weapon system occurs.

Explanation of the essence of the invention

The invention has for its object sine apparatus for Schußzahlerfassung, especially in sports rifles to create that allows a precise pulse detection with respect to the actual number of fired shot without a mechanical or electrical connection to the system of the sporting gun.

According to the invention, this object is achieved in that a permanent magnet is attached to a movable striking piece, that further a magnetic sensor is arranged such that caused by the impact piece movement approximation of a permanent magnet to a magnetic sensor connected to a known per se electronic meter with digital display is leading to a pulse-controlled shot count. With an indented pawl, the way a striking piece is so limited that the so limited approach of a permanent magnet to a magnetic sensor does not lead to the triggering impulse and darr.it is not registered by the electronic counter.

embodiment

The apparatus according to the invention for determining the number of picks is to be explained in more detail below on an exemplary embodiment. In the ζ (corresponding drawing shows:

Fig. 1: Device during dry training - no impulse triggering Fig. 2: Device at Schußzahlerfassung - with impulse triggering

Fig. 1 shows a movable striking piece 1 of a COj-powered sports rifle, which is thrown by a percussion spring 2 against a valve lifter 3. A pawl 4, which can be engaged in the direction of the hammer axis, prevents the actuation of the valve stem 3 for the purpose of dry training, in which also no SchuL'zählung may take place. At the percussion piece 1, a permanent magnet 5 is fixed, which does not allow pulse triggering at its limited movement. The exact shot count of FIG. 2 is realized in that when not engaged pawl 4, d. H. with unlimited movement of the hammering piece 1 of the permanent magnet 5 as far as the magnetic sensor 6 (REED contact or Hall-tiement) contactless approaches, so that a pulse is triggered. The pulse thus generated carries in the battery-operated electronic counter 7 with visible digital display for detecting the number of shots. In vorteilhsiter, the visible digital display further stored or retrievable information such as competition time, shot series, total shot number u.a. be taken from the shooter at any time. Specific information allows conclusions about a timely change of CCV cartridges or preventive maintenance on the sports rifle.

The inventive apparatus for determining the number of shots is according to the o.g. Ausführungsbeispkies easily on a movable firing pin, which impinges on a firing cartridge or projectile, generally transferable to all military weapon systems.

Claims (2)

1. Apparatus for determining the number of shots, especially in sports rifles by means of electronic counter, characterized in that on a movable striking piece! Your permanent magnet (5) is fixed, that further comprises a magnetic sensor (6) is arranged such that caused by the impact piece movement approximation of a permanent magnet (5) to a magnetic sensor (6), which is connected to a known electronic counter (7) with digital display, leads to a pulse-controlled shot count. 2. Apparatus for collecting the number of shots according to claim 1, characterized in that at an engaged pawl (4) the way of a striking piece (1) is limited so that the so limited approach of a permanent magnet (5) to a magnetic sensor (6) does not cause a pulse triggering and thus realized no shot number detection.
