  • Patent number: 6070569
    Abstract: A bow arm support stabilizer system for supporting the weight of the bow while aiming and shooting is disclosed. The system has a horizontal connecting shaft with a rear end attached to the riser section of the bow through a single stud received in the threaded bore conventionally formed in the riser section. A pair of clamping arms attached to the horizontal connecting shaft extend rearwardly to locate clamping jaws respectively adjacent side surfaces of the riser section. The clamping arms are pivoted on the horizontal section to urge the jaws into clamping contact with the riser section. A telescopic support rod assembly is pivotally mounted to the front end of the horizontal shaft. The rod assembly includes at least three rods telescopically connected together with internal locking mechanisms between adjacent rod sections to effectively control the length of the rod assembly by rotation of one rod relative to another in a locking direction or reverse rotation in an unlocking direction.

  • Patent number: 5509400
    Abstract: A bow arm support stabilizer system for supporting the weight of the bow while aiming and shooting is disclosed. The system has a horizontal connecting shaft with a rear end pinned to the riser section of the bow beneath an intermediate hand grip portion thereof. A pair of closely vertically spaced pins projecting forwardly from the forward facing edge of the riser section are received in corresponding axial bores formed in the shaft rear end to provide a non-rotational connection. A strap may be used to connect the shaft rear end to the riser section. A telescopic support rod assembly is pivotally mounted to the front end of the horizontal shaft. The lower end of the support rod assembly is provided with a rubber cap adapted to frictionally engage the top of the archer's shoe to support the bow through the support rod assembly and the horizontal shaft.

  • Patent number: 4462598
    Abstract: A target system includes a target sheet (10) comprising a polyester film (20) adhesively secured to a paper or polyethylene backing sheet (15). The polyester film (20) defines an exposed target surface (F) and includes a plurality of circular target strike zone portions (T) defined by spaced apart slits (S) perforating the polyester film (20). The circular target zone portions (T) are not adhesively secured to the backing sheet (15) and are integrally connected to the polyester film (20) with connecting portions (30) each located between adjacent slits (5). A rounded impact head (42) of a projectile (40) striking a target portion breaks the connecting portions (30), causing the target portion (T) to detach from the polyester film (20) and be pulled through the backing sheet (15) to achieve a vanishing effect. In another embodiment, separate zone portions (T) can be secured to the backing sheet with minute adhesive portions (25') or adhesive tape (32).
