  • a jig is off US 6,868,845 B1 known.
  • the invention further relates to a crossbow having a shaft extending in the weft direction for receiving a projectile, in particular an arrow or a round ball, and having two limbs rotatably or pivotably connected to the shaft, to which a tendon provided for engagement in the projectile is attached.
  • Crossbows are well known in the art and are used in both sports and hunting.
  • a crossbow In contrast to bows, in which an arrow is first brought into engagement with a tendon and then the limbs of the bow are stretched by the shooter's power, in a crossbow the limbs are first stretched by retracting the tendon connected thereto and then a bullet, for example, an arrow, engaged with the tendon.
  • the limbs are tensioned either solely by the shooter's power, with support from tensioning devices such as tension levers or winches, or solely by tensioning devices which, for example, displace the limbs in the longitudinal direction of the crossbow towards a triggering device or against an abutment.

  • WO 01/92808 A1 From the WO 01/92808 A1 goes out a motor-spanned crossbow, which has a battery-powered electric motor, which is connected to a threaded rod. This threaded rod shifts a trigger block engaging the string to be clamped along the crossbow. Swiveling limbs are attached to the main body of the crossbow, which enables space-saving transport or space-saving storage.

  • the bow on pivotally mounted arms whose position is adjustable by means of at least one adjustable in length device, such as a reciprocating piston, whereby the tension of the tendon can be changed.
  • a disadvantage of known crossbows is that the clamping process is time-consuming and also effortless with simple models. Often, the shooter has to leave his lying position, for example, to stretch the crossbow, in which case tensile forces of up to 150 kg are common. Manual clamping operations can take more than 30 seconds and are cumbersome, especially when levers or winches are to be operated. Even with electric drive devices for tensioning the limb of the crossbow, the tensioning process often takes too long to achieve a sufficiently high firing order and deliver a second shot to a moving target. In addition, such crossbows are usually heavy and unwieldy.
  • the object of the present invention is to provide an above-mentioned tensioning device for a crossbow or a comparable device, which allows a rapid and preferably low-noise tensioning of the crossbow without effort by the shooter.
  • the shooter should not or only slightly change his shot position or posture for the clamping process.
  • the clamping device should allow a compact transport of the crossbow, which should be transferred without tools from a space-saving transport position in a bullet-ready position.
  • the construction should be simple, robust and inexpensive to build.
  • the clamping device should preferably be suitable for retrofitting existing crossbows, but can also be integrated in appropriately developed crossbows. Disadvantages of known clamping devices should be avoided or at least reduced.
  • the object of the present invention is also to provide an above-mentioned crossbow having the advantages mentioned in connection with the tensioning device.
  • the object of the invention is achieved in terms of the clamping device in that the connecting element is connected to at least one connectable to the limbs driving device with which the limbs from a first position in which the limbs with the shaft include a first angle, in a second position, in which the limbs include a second angle with the shank, are rotatable or pivotally translatable, wherein the second angle is greater than the first angle, to transfer the limbs and a tendon connected thereto from a relaxed position to a ready-to-shoot, cocked position.

  • the crossbow has, in a manner known per se, a shaft which is designed to receive and guide a projectile to be shot, in particular an arrow.
  • the shank extends in the longitudinal direction, ie in the intended weft direction, of the crossbow and is connected to two limbs at or near an end facing away from the shooter in the use position of the crossbow.
  • the two limbs are elastically deformed or bent in order in this way generally to store therein the energy which is provided for the acceleration of the projectile.

  • the drive device can be connected directly to the limbs in order to pivot them.
  • the drive device is configured to deliver the rotatable limbs received in the attachment device from a first position in which the limbs enclose with the shaft at a first angle to a second position at which the limbs enclose a second angle with the shaft pivot.
  • the second angle is greater than the first angle, both angles between the limbs and the shaft are considered towards the shooter facing the end of the shaft.
  • the limbs take the first angle to the shaft, these and the associated tendon in a relaxed position in which the shooter essentially without effort, ie without having to stretch the crossbow or without deforming the limbs, the tendon with a triggering device of the crossbow can engage. In this position the limbs and the tendon are not stretched. If, on the other hand, the limbs occupy the second angle to the shaft, these and the associated tendon are in a ready-to-fire, tensioned position, in which the energy required for the acceleration of the projectile is stored in the limbs.
  • the tensioning device can be provided as a fixed part of a crossbow or a comparable device or can be used as a retrofitting device for existing crossbows or similar devices.

This process is of course only after the projectile was fired and is triggered by the limbs or the tendon. The position of the limbs or tendon can be used to operate the deactivation device.
  • the limbs can automatically, without manual intervention by the shooter, pivot in the direction of the shaft due to the tension still maintained across the tendon. In this way, the return of the limbs takes place in a very short time.
