  • Patent number: 6505619
    Abstract: An arrow fall-off bumper system for maintaining an arrow in the desired position upon an arrow support rest. The arrow fall-off bumper system includes a side support member that is threadably attached within a threaded aperture of a bow adjacent a support rest. The side support member is generally comprised of a threaded shaft and a head wherein the head engages the shaft of the arrow when accidentally removed from the support rest. The head is preferably rounded and comprised of a molded rubber cap to reduce damage to the arrow. At least one spacer washer may be utilized to adjust the position of the head with respect to the support rest.

  • Patent number: 6488018
    Abstract: An arrow holding device for retaining an arrow within an arrow support rest until the user is prepared to shoot without affecting the flight of the arrow. The arrow holding device includes a base plate that is attachable to the support rest, a guide arm extending from the base plate, a securing strap attached to the base plate, and a ring member attached to the distal end of the securing strap for removably engaging the guide arm. The securing strap is positioned about the shaft of an arrow and then the ring member is positioned upon the guide arm to prevent movement of the arrow within the support rest. When the user draws the arrow rearwardly the securing strap moves rearwardly until the ring member is pulled from the guide arm thereby releasing the securing strap from about the shaft of the arrow.

  • Patent number: 6390084
    Abstract: An arrow holding device for retaining an arrow within an arrow support rest until the user is prepared to shoot without affecting the flight of the arrow. The arrow holding device includes a base plate, a U-shaped bracket attached to the base plate for attaching to a groove within a support shaft of a support rest, a guide arm extending from the base plate, a securing strap attached to the base plate, and a ring member attached to the distal end of the securing strap for removably engaging the guide arm. A fastener extends through the U-shaped bracket for allowing tightening about the support shaft. The securing strap is positioned about the shaft of an arrow and then the ring member is positioned upon the guide arm to prevent movement of the arrow within the support rest. When the user draws the arrow rearwardly the securing strap moves rearwardly until the ring member is pulled from the guide arm thereby releasing the securing strap from about the shaft of the arrow.
