Abstract: A portable sports practice net includes a frame with a base to which removable vertical poles having top side bar supports are joined holds a net to create an opening, such as a goal opening. The top side bar supports have a unique shape and extend horizontally from the top of the vertical poles in a manner that reduces the weight placed on the net fabric hung between the vertical poles. The top side bar supports also create a depth of the goal pocket without need for additional vertical posts. Each vertical post creates a pivot point at its bottom end, such that each vertical post is urged apart from the other post to create tension or leverage between the opposite top side bar supports, thus creating a net opening with a more realistic goal shape and reducing sag at the top edge.

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.
