The present invention concerns a system and method for shooting arrows at a target. It finds its application in the area of archery.
Conventional archery requires a large field equipped where necessary with systems for protecting against dangers from the arrows. The shooting distances give rise to a not insignificant time for picking up arrows which, moreover, present a certain danger for the archers and spectators. In addition, the targets (that is to say fixed targets) are rapidly damaged by impact from the arrows.
The present invention completely or partly remedies the drawbacks of the practice of traditional archery. In particular it proposes a novel technique for limiting the travel of the arrows to shorten the distances that the archer must travel to pick up the arrows.
Another advantage of the invention, in a preferred embodiment, is to greatly eliminate the risks of accidents by virtue of arrows having a protective end piece.
Other aims and advantages will emerge during the following description of an embodiment of the invention. First, it is indicated that the invention concerns a system for shooting arrows at targets, comprising at least one arrow-shooting device, at least one target and at least one arrow, characterised by the fact that it comprises a reflection wall and that the arrow comprises a head portion, the reflection wall and the head portion being configured so as to at least partially absorb the energy of the impact and to restore it in order to send the arrow in the direction of the shooting device when the head portion impacts the reflection wall instead of the target.
In advantageous but optional embodiments, which may be concurrent or used alternatively, the system is such that:
-
- the target is configured to damp an impact of the head portion more than the reflection wall;
- the reflection wall is a substantially vertical wall;
- the head portion comprises an elastically deformable end piece and means of connection to an arrow shaft;
- the end piece is made from a flexible plastics material;
- the end piece is made from polymer foam;
- it comprises a machine for launching the at least one target, said machine being configured to launch the target in front of the reflection wall relative to the shooting device;
- the machine is configured to launch the at least one target in a vertical plane;
- the vertical plane is closer to the reflection wall that the shooting device;
- the reflection wall and the vertical plane are parallel and spaced apart by a distance of between 1 metre and 3 metres, in which the shooting device and the vertical plane are spaced apart by a distance of between 7 metres and 11 metres;
- the reflection wall has a height of between 7 metres and 12 metres;
- it is configured so that the arrow is returned at a distance of between 50% and 85% of the distance between the reflection wall and the shooting device when it impacts the reflection wall;
- the external shape of the at least one target is a portion of a cylinder.
The invention also concerns a method for shooting arrows at a target for an archer comprising a step of shooting an arrow in the direction of the target, characterised by the fact that it comprises the following steps:
-
- placing a reflection wall in a shooting area around the target;
- forming a head portion on the arrow;
- when the arrow does not impact the target, returning the arrow towards the archer by bouncing of the head portion on the reflection wall.
According to preferred embodiments, this method is such that:
-
- the arrow is returned at a distance of between 50% and 85% of the distance between the reflection wall and the archer;
- the target is launched prior to the shooting step so as to make it move in front of the reflection wall relative to the archer during the shooting step;
- the target is launched at a height greater than 2 metres and less than the height of the reflection wall.
The invention will be better understood in the light of the appended sets of drawings, presenting a preferred embodiment of the invention, and which is comprise:
As depicted in
An example of an arrow 3 that can be used is shown in
It should be noted that it be advantageous for at least one portion of the arrow 3 to have a predetermined colour. This may for example be the head portion 4. Thus, when a plurality of arrows 3 are used, it is possible to identify them or to identify the sets of arrows 3 in particular to dedicate a colour to an archer 1. It is consequently easier to count the number of hits achieved by the user.
Returning to
According to a first possibility, the target 5 is fixed relative to the reflection wall 6 and is for example simply fixed to the surface of the wall 6. According to another possibility, which is preferred, the target 5 is able to move in front of the reflection wall 6, as can be seen in
The type of target 5 is not limited by the invention. However, advantageously, at least one target 5 will be used in the form of a cylinder portion that may for example have a diameter varying from 15 to 40 centimetres and advantageously between 25 and 33 centimetres with a thickness of between 3 and 10 centimetres. The target 5, thus forming a kind of disc, is preferably produced from a polymer material in one or more layers. For example, a polymer foam with a density of between 25 and 160 kg/m3 is satisfactory. Advantageously, the faces of the disc are substantially flat, which does not exclude some reliefs in particular for improving the visibility of the target when it is moving, in order to improve its stability, or the like. Advantageously, the target 5 is projected so as to effect a movement upwards and then downwards in a vertical or substantially vertical plane. Optionally, a slight inclination may be produced in particular when it is wished to modify the projection effect and to vary the difficulty of shooting. Advantageously, the faces of the target 5 are substantially parallel to the reflection wall 6 during the movement.
Always, preferably, the target 5 is launched opposite the archer 1 at a distance of between approximately 7 and 11 metres, represented by the dimension L3 in
Taking the example of
An example of a method used for launching it from the target 5 is given below. The example given below may be reproduced for a plurality of targets 5.
More particularly,
The reflection wall 6 is advantageously made from rigid material so as to produce a bounce that is effective as possible of the arrow 3 equipped with the elastically deformable head portion 4. However, another solution consists of the surface of impact of the arrow 3 on the reflection wall 6 also being elastically deformable or elastically deformable in replacement for the elastic deformability of the head portion 4. The general principle remains that the arrow 3 undergoes a bounce after an impact on the reflection wall 6. Thus any configuration for at least partially absorbing the energy of the impact and restoring it in order to reflect the arrow 3 in the opposite direction to the shooting is suitable.
With reference to
In
At this level, the arrow 3 re-descends substantially in front of the archer 1 at a distance that can be adjusted according to the shooting conditions and the elastic deformation properties enabling the bounce.
For example, the system may be configured so that the arrow is returned at distance of between 50% and 85% of the distance between the reflection wall 6 and the shooting device 2. To achieve this, it is possible to dispose a rigid reflection wall 6 (its surface is hard) at a distance of 10 metres from the archer 1 and the launch machine 7 so that it projects the targets 5 at a distance of 1.5 metres in front of the reflection wall 6. With a bow the power of which is intentionally limited to 26 pounds and an arrow 3 comprising a spherical head portion 4 that is 65 millimetres in diameter made from elastic polymer foam, it is possible to achieve an initial speed of the arrow 3 of around 30 to 40 metres per second. This speed decreases greatly because of the relatively high weight of the assembly formed (for example between 30 and 40 grams and preferentially 35 grams) including a majority placed at the head portion (for example between 20 and 25 grams). It should be noted that the spherical portion of the head portion 4 is also not very aerodynamic, which promotes deceleration. With these parameters and the reflection wall 6 consisting of a conventional rigid wall, it was found surprisingly that the arrow could be made to bounce so that it lands approximately 2 to 3 metres in front of the archer in the event of the target 5 having been missed. This distance may easily be adapted by acting on the properties of elasticity during bounce and the shooting speed.
