Abstract

An archery bow riser having an elongated central body and two opposing arms attached at the far end of the central body and extending outwards to attach opposing bow limbs. The central body having a stabilizer tube support channel extending along a portion of the body, to which is fitted a stabilizer tube. The stabilizer tube slidably engaging the stabilizer channel, the stabilizer tube and channel having cooperating locking means to lock the tube in the channel in a full draw position. The riser having a draw handle design comprising two half handles. The half handles, when drawn and held together after stabilizer tube to channel lock, maintain the bow string at full draw tension. The riser having a plurality of mounting positions for an adjustable front handle. The adjustable front handle providing universal fit of the riser to a variety of users. The in close riser design providing improved balance. The riser body together with the stabilizer tube and channel providing improved stability and accuracy. The short draw providing use of shorter and faster arrows; and the split half handle design providing a greatly extended full draw hold time due to reduced muscle strain and the transfer of full draw muscle load from the back to the fore arm.

Claims

exact text as granted — not AI-modified
I claim:  
     
         1 . A riser for an archery bow providing universal fit while allowing archers to use a shorter, faster arrow, the riser comprising: 
 (a) a riser central body having an opposing far end and a near end wherein the near end is closest to an archer and the far end is furthest from the archer and provided with a plurality of mounting locations along a portion of the central body between the near end and the far end; and    (b) a front handle which can be moveably repositioned to user selected mounting locations along the central body to fit the bow draw length to multiple archers.    
     
     
         2 . The riser for an archery bow of  claim 1 , wherein: 
 (a) a stabilizer tube support channel fixed to the central body at a position between the near end of the central body and an axis defined by a bow string rest position; and    (b) a stabilizer tube having a portion thereof slibably mounted inside the support channel, the stabilizer tube extending outwards beyond the near end of the central body providing a leverage holding point for stability of bow.    
     
     
       I claim:  
     
     
         1 . A riser for an archery bow providing universal fit while allowing archers to use a shorter, faster arrow, the riser comprising: 
 (a) a riser central body having an opposing far end and a near end wherein the near end is closest to an archer and the far end is furthest from the archer and provided with a plurality of mounting locations along a portion of the central body between the near end and the far end; and    (b) a front handle which can be moveably repositioned to user selected mounting locations along the central body to fit the bow draw length to multiple archers.    
     
     
         2 . The riser for an archery bow of  claim 1 , wherein: 
 (a) a stabilizer tube support channel fixed to the central body at a position between the near end of the central body and an axis defined by a bow string rest position; and    (b) a stabilizer tube having a portion thereof slibably mounted inside the support channel, the stabilizer tube extending outwards beyond the near end of the central body providing a leverage holding point for stability of bow.    
     
     
         3 . An archery bow riser providing muscle transfer for extended full draw hold time, the riser comprising: 
 (a) an elongated central body portion having a near end and an opposing far end, the riser having two opposing arms attached to the far end of the central body portion, the central body portion positioned intermediate and substantially perpendicular to the opposing arms, the arms extending outwards and coplanar with the central body portion, the each arm equipped to mountably attach a flexible bow limb, the central body portion provided with a means of mounting an arrow rest thereto;    (b) a stabilizer tube support channel mounted to and extending along a portion of the riser central body, the support channel having a slot terminating in a locking point;    (c) a stabilizer tube having a near end and a far end, the far end and a portion of the stabilizer tube slidably mounted inside the support channel, the far end having a locking pin affixed to and protruding radially from the stabilizer tube, the locking pin sized to slidably engage and ride within the support channel slot, the locking pin sized to retentively engage the locking point when the stabilizer tube is extended to a fill draw position; and    (d) a draw handle assembly comprising: 
 i. a front half handle having an upper and lower end, the upper end having a half handle alignment tube and a trigger release bow string retention means mounted thereto,  
 ii. a rear half handle fixedly attached to the near end of stabilizer tube, the rear half handle having a handle alignment rod sized and positioned to be slidably received in the half handle alignment tube such that the front half handle and the rear half handle when drawn and held together are positioned in mating confronting alignment by the alignment tube and alignment rod, the front half handle and the rear half handle being sized and formed to produce a complete draw handle when drawn together by an archer's hand and forearm muscles, the trigger release bow string retention means releasably drawing and tensioning the bow string as the front half-handle is drawn to mate together with the rear half handle, the alignment rod and tube aligned to permit bow string tension force to retract the front half handle and trigger from the rear half handle, thereby release bow string tension when the archer's hand grip is released.  
   
     
     
         4 . The archery bow riser of  claim 3  wherein the riser includes at least one connecting support member extending between central body and arms.  
     
     
         5 . The archery bow riser of  claim 4 , wherein at least one connecting support member is two connecting support members.  
     
     
         6 . The archery bow riser of  claim 4 , wherein a means is provided for mounting a cable guard to the connecting support member along a portion thereof laterally offset from the central body of the riser, and a means is provided for mounting a site to a portion of an arm of the riser.  
     
     
         7 . The archery riser of  claim 3 , wherein the stabilizer tube support channel has a tapered capture point and wherein the support channel is detachably mounted to the riser central body by a plurality of screws.
