  • an arrow magnet 126 forms a part of the arrow point, and is located in a predetermined position on the arrow.
  • the arrow point component 120 can have a portion 124 that also forms the arrow magnet, and that portion 124 can be configured to be inserted and fixed in an opening in the arrow shaft (for example the portion 124 can be adhesively secured in the opening in the arrow shaft).

The support magnet 110 is configured to establish a magnetic field that interacts with the arrow magnet 124 and supports the arrow 100 as the arrow is being drawn and released by a bow 102, so that the arrow is magnetically supported and in part by the interaction between the support magnet 110 and the arrow magnet 124 as the arrow is drawn by the bow and released toward a target.

  • the support magnet 110 preferably comprises a ring with a central opening 110a configured so that the arrow can be at least partially drawn through the central opening and then projected at least partially through the central opening without physical interference from the central opening as the arrow is drawn by a bow and then released toward a target.
  • the ring 110 is also preferably formed of one or more components, that are either magnetic material or of material that can be magnetized as an electromagnet.
  • a support magnet 110 that is ring shaped is preferred because it is relatively steady, and creates a magnetic field that surrounds the arrow magnet as the arrow is being drawn and released by a bow.
  • Figures 2-5 schematically illustrate the magnetic field of the support magnet 110, and the relationship of the arrow magnet 124 to that magnetic field as the arrow is being drawn by a bow string 108.
  • the N/S poles of the support magnet 110 are preferably on opposite faces of the ring, and the N/S poles of the arrow magnet 124 are preferably on opposite ends of the arrow magnet.
  • a radially magnetized ring may also be used.
  • the support magnet 110 when the support magnet 110 is ring shaped, the support magnet should have sufficient strength to withstand the physical and magnetic forces thereon as an arrow is drawn and projected by the bow, and the central opening 110a should be relatively close to the arrow 110, but with sufficient clearance that the arrow should not physically contact the ring 110 as the arrow is drawn by the bow and projected toward a target.
  • the preferred dimension of the ring shaped support magnet 110 is 2 inch outer diameter, 1.4 inch inner diameter, and 3 / 4 inch thickness.
  • the support magnet 110 is configured to establish a magnetic field in a predetermined orientation to the bow, to magnetically affect the orientation of an arrow magnet 124 forming part of an arrow that is being drawn and released by the bow.
  • the support magnet preferably includes the central opening 110a, and the magnetic field incorporates at least a portion of the central opening.
  • the central opening 100a is configured to allow the arrow 100 to extend through the central opening without physical interference from the support magnet as the arrow is being drawn and released by the bow.
  • the support magnet preferably comprises a ring shaped magnet. Moreover, the ring shaped magnet can be formed of magnetic material.
  • the arrow magnet and/or the support magnet can be formed in different ways, and still perform according to the principles of the present invention.
  • the arrow magnet and/or the support magnet can be formed of magnetic material, and thereby configured as a permanent magnet.
  • the arrow magnet and/or the support magnet can be configured of material that can be magnetized, as with an electromagnet.
  • the arrow magnet 124 is in predetermined relation to the point component of the arrow, it is contemplated that an arrow magnet may be located at other predetermined locations on the arrow, and still achieve the objectives of the present invention.
  • the support magnet 110 is shown as attached to the bow, it is contemplated that the support magnet can form a part of the bow.

Abstract

L'invention concerne une structure nouvelle et utile qui permet de supporter et de guider une flèche armée et décochée au moyen d'un arc, d'une manière qui évite le contact physique entre la structure et la flèche. L'invention concerne également des composants nouveaux et utiles pour cette structure. Une structure préférée comprend un aimant de support (110) destiné à un arc (102) et une flèche (100) dotée d'un aimant de flèche (124) dans une position prédéterminée sur la flèche. L'aimant de support est conçu pour établir un champ magnétique qui supporte et guide la flèche lorsque celle-ci est armée au moyen d'un arc. L'aimant de la flèche, qui est disposé dans une position prédéterminée sur la flèche, est conçu pour réagir avec le champ magnétique établi par l'aimant de support, de façon que la flèche soit magnétiquement supportée et guidée par l'aimant de support, sans contact physique entre la flèche et l'aimant de support, au moins partiellement lorsque la flèche est armée au moyen d'un arc et décochée en direction d'une cible.
