This is a national stage of PCT/NZ09/000,136 filed Jul. 8, 2009 and published in English, which claims the priority of New Zealand number 569677 filed Jul. 8, 2008, hereby incorporated by reference.
This invention relates to a trench/bunker trap machine and particularly to a clay target trap machine which emulates the International Shooting Sport Federation (ISSF) regulations for Olympic trap shooting (known as Olympic trap, Olympic trench or Olympic bunker shooting) and which replicates in one unit the ability to throw targets from more than one position and at a number of different firing angles.
Trap shooting as an Olympic sport is operated under the rules of the ISSF. The rules set out the competition formats which have in the past required the use of fifteen purpose built machines located in a bunker. The individual machines are capable of being preset to throw targets at regulation heights and angles which are set down in the competition rules. Full details of the rules are available from the website of the ISSF which is available at www.issf-shooting.org/rules and the rules are incorporated herein by way of reference as if they were set out herein.
The cost of setting up a standard bunker is significant and because of this they are generally situated near major population centres to maximize usage. This constitutes a limitation on expansion of the sport and may mean that an out of town user incurs significant travel cost for regular practice.
In the past single target trap throwing machines have been used as a practice option for Olympic trap (regulation ISSF Olympic trap). However these single trap machines do not provide adjustable settings and they only fire from one position therefore limiting the angular orientation of the practice and not replicating competition format.
An object of the presentation is to overcome these disadvantages and provide a more affordable alternative Olympic trap clay target trap machine which is able to emulate the International Shooting Sport Federation (ISSF) regulations regarding target release positions, angles and height trajectories. Such a machine at least offers a useful alternative choice.
Further objects and advantages of the invention will become apparent from the following description which is given by way of example only.
According to the present invention there is provided a positioning mechanism/machine including a single clay target throwing machine and associated target hopper or magazine mounted on a base, the base being mounted on a carriage movable automatically on rails, channels or the like between positions which replicate any of the fifteen standard target release positions of a bunker/trench trap layout or ABT layout relative to a shooters firing position.
The orientation of the throwing machine being automatically adjustable by a control system so that in each of the three positions the single clay target throwing machine replicates the heights and angles required by ISSF regulations for the standard fifteen clay target throwing machines in a standard competition bunker.
The single clay target throwing machine can be mounted on the carriage on mountings with drive means capable of automatically, under the control of a computer based control system, adjusting the angular orientation of the throwing machine on X, C and Z axes.
The carriage can be mounted on a base frame designed for mounting in a trench or a bunker.
The base frame can have a set of spaced apart rails, for example a pair of opposed rails each of which is a lipped channel rail on which the carriage is mounted.
The carriage can be mounted on sliders which run in the lipped channel rails.
The carriage is moved on the rails by any suitable means such as a driven chain, belt or hydraulically/pneumatically by rams. Preferable the carriage is moved by way of a chain driven by an electric motor also controlled by the computer based control system to thereby move the carriage between selected positions on the track.
The target hopper can be a ten column carousel capable of storing up to 350 clay targets. This carousel can be of any number of columns holding any number of clay targets. Alternatively a magazine or the like can be used to store the clay targets. Such a carousel is described in U.S. Pat. No. 6,588,410.
In use any of the variety of known voice release, phono pull, systems can be used to activate release of the targets during practice or competition.
Further aspects of the invention which should be considered in all its novel aspects will become apparent from the following description which is given by way of example.
A particular example of the invention will now be described with reference to the accompanying drawings in which:
In the example of the invention shown similar parts are referenced by the same numerals.
In
The machine 1 is mounted on a carriage sub-frame 8 via a column or pillar 9. The position of machine 1 on the pillar 9 can be adjusted in a vertical plane through an horizontal axis by an electric motor and gearbox 10.
The position of pillar 9 can be adjusted around in an horizontal plane through the vertical axis by electric motor and gearbox 11.
The movement of the motors and gearboxes 10, 11 is controlled by a computer controller (not shown) which can be preset so that at different positions in the bunker the targets are thrown in accordance with the ISSF regulations.
The carriage sub-frame 8 is mounted on rails, channels or the like 12 which are mounted on a base 13 which in the example shown is an elongate frame with uprights 14 and cross members 15 shown in detail in
The sub-frame 8 is preferably mounted on sliders 16 which run in the rails between positions which replicate three standard positions of a 15 trap bunker layout.
As used herein X, C and Z axes are defined as follows when a person looks at the throwing machine in plan view (from overhead):
In the example, as shown in
The target hopper of the machine 1 can be a ten column carousel capable of storing up to 350 clay targets—or it could be any number of columns capable of storing any number of clay targets.
In use the machine 1 is mounted as shown in
The bunker 22 is itself part of a field layout shown in
In use the orientation on the sub-frame 8 of the machine 1 is automatically adjustable by the control system so that it is moved automatically and sequentially between each of its three positions A, B, C (shown in
In addition in each position A, B, C the vertical height of the thrown clay target can automatically be adjusted in the direction of target flight (the arrows 27 and 28 in
The control system may include a computer program which allows a number of pre-programmed selections to be made so that in any practice session or competition session a desired regular format is reproduced by the machine. In practice a voice release system can be used to activate firing of each target.
The single clay target throwing machine therefore replicates the heights and angles required by ISSF regulations for the standard fifteen clay target throwing machines in a standard competition bunker and is fully compliant with ISSF regulations in relation to target height, position and angle as referenced to the shooters position. The applicant's owners manual, the content of which is incorporated herein by way of reference incorporates a detailed explanation of how to set up one of the clay target throwing machines for competition or practice use.
Advantages of the invention include the following:
Where in the preceding description particular mechanical integers are described it is envisaged that their mechanical equivalents can be used as if described herein.
Thus by the invention there is provided an alternative clay target trap machine which is fully compliant with International Shooting Sport Federation (ISSF) regulations in relation to target height, position and angle as referenced to the shooters position.
A particular example of the invention has been described and it is envisaged that improvements and modifications can take place without departing from the scope of the attached claims.
