  • Patent number: 11512922
    Abstract: An apparatus is described that is operable between a raised and lowered position for lifting an object without pivot or rotational joints. The apparatus may include an arrow rest for use with an archery bow, wherein the arrow rest has arrow support members operable to form a v-shaped arrow supporting notch, wherein the support members slide in a non-pivotal, non-rotational manner to vary a depth of the v-shaped notch. The support members are oriented to slide between a raised and lowered position. The arrow rest is suitable for coupling to the bow in a manner so that as the bow string is drawn the support members raise the arrow into a shooting position, and when the bow string is released the support members slide away from the arrow to avoid contact between the arrow and support members. Further, the arrow rest is adjustable to accommodate various diameter arrow shafts and to adjust the lateral and vertical orientation of the arrow shaft relative to the riser.

  • Patent number: 10605560
    Abstract: An apparatus is described that is operable between a raised and lowered position for lifting an object. The apparatus may include an arrow rest for use with an archery bow, wherein the arrow rest has arrow support members operable to form a v-shaped arrow supporting notch, wherein the support members move in a lateral manner to vary a depth of the v-shaped notch. The support members are oriented to actuate between a raised and lowered position. The arrow rest is suitable for coupling to the bow in a manner so that as the bow string is drawn the support members raise the arrow into a shooting position, and when the bow string is released the support members actuate away from the arrow to avoid contact between the arrow and support members. Further, the arrow rest is adjustable to accommodate various diameter arrow shafts and to adjust the lateral and vertical orientation of the arrow shaft relative to the riser.
