Abstract: A reinforced archery arrow shaft includes a tubular core, with an attached fabric sleeve covering the core. The core may include carbon therein. The sleeve is formed from a fabric material, which is wrapped around and affixed to the core. Preferably, the sleeve fabric carries a decorative design or pattern on the exterior surface thereof. In a method of making an arrow, a piece of fabric is placed covering a hollow tubular core, and is affixed thereto. Then, a resin or protective composition, associated with the fabric material, is cured to adhere the fabric to the core. The resin may be impregnated into the fabric prior to its placement on the core, or alternatively, may be applied to the fabric by conventional methods such as spraying, dipping, brushing, or powder coating. The shaft may be treated to make the exterior surface smooth after curing. Optionally, accessories may be attached to the arrow shaft to form an arrow.

Abstract: A deflection-resistant arrowhead includes a support body with a fixed spear-point blade attached to the tip thereof, and a plurality of pivotally attached, mechanically expandable blades. The expandable blades include integrally formed spurs at end portions thereof, which are provided to extend outwardly from the front of the support body, adjacent the base of the fixed blade, when the expandable blades are closed. The support body has slots formed in the sides thereof, to receive the pivotally attached expandable blades. The support body is also slotted at the front central portion thereof to receive the base portion of the fixed blade. The expandable blades normally remain in a closed configuration thereof, by means of an elastic retaining ring located behind the spurs. Upon contact with a target, the outstanding spurs force the expandable blades to open, simultaneously moving the retaining ring rearwardly on the support body.

Abstract: A folding chair, which is foldably collapsible in a scissors-like folding operation, forms a long narrow bundle when collapsed, which fits into a tubular bag. The folding chair includes a pivotally jointed backrest support member which can be placed in various configurations to allow reclining movement thereof. The folding chair includes a frame assembly and a flexible hammock-type of fabric seat member which is mounted on, and supported by, the frame assembly. In a preferred embodiment, the frame assembly includes a plurality of interconnected X-members. The X-members cooperate to define a cage member when the chair is in an open configuration thereof. The frame assembly further includes a position fixing mechanism for temporarily and disengagably fixing the position of the seat back, to allow the frame assembly to be temporarily locked in a particular orientation thereof.

Abstract: A filtering pump assembly for pumping and filtering a fluid includes a pump subassembly and a filter subassembly. The pump subassembly has an inlet portion with a first cross-sectional shape. The preferred cross-sectional shape of the inlet portion is circular. The filter subassembly includes a foraminous cage member, having an opening formed therein of a shape corresponding to the first cross-sectional shape of the inlet portion and being configured to fit engagably thereon. The filter subassembly also includes a filter element formed of a porous material for placement in covering relation to the cage member. The preferred filter element is either bag-shaped or formed as a cylindrical sleeve. Preferably, the filter assembly includes a retainer for retaining the filter element in covering relation to the cage member. The retainer may be an annular spring clip having two ends which overlap one another, and having a finger grip formed at each end thereof.

Abstract: A safety harness especially for hunters who use tree stands is disclosed. The harness comprises a web belt with a buckle for the hunter. Attached to the belt by a "D"-ring is a safety rope which is fastened around the tree and back onto the "D"-ring by a cammed-hook assembly to secure the hunter from falling. The harness is easily portable and is usable both as a climbing harness and as a tether while the hunter is on the tree stand.

Abstract: An ultrasonic sound producing apparatus for mounting on a vehicle to warn animals of the approach of the vehicle includes (a) a housing, (b) an electrically actuated member for generating an electric tone, and (c) a base for supporting the housing and for mounting the apparatus to a vehicle. In a preferred embodiment, the tone generating member includes a piezoelectric crystal.

Abstract: A bow press for facilitating the re-stringing of a split limb bow includes a pair of spaced apart handles which engage the exterior of the limbs via the slots formed therein. A rotatable lever to which the handles are interconnected, when rotated from a first position to a second position, causes inward compression of the limbs toward each other. An adjustment rod, which is variable in length, reduces or extends the length between the two handles to accommodate bows of various sizes.

Abstract: A bow square 10 is defined by a T-shaped planar member 12 having calibrations 18 along the length of each leg 14,16 on each face thereof. The bow square 10 includes a slidably adjustable gauge 22 which is mounted on one leg for enabling proper location of a nocking point, a kisser button and/or peepsight. Leaf spring clip mounts 24 enable multi-positioning of the bow square 10 onto a bow string 52.
