Abstract:
This invention is directed to a firearm safety device that has a chamber block for being received in a chamber of a firearm. An internal area is defined in the chamber block and can receive a bullet so that the bullet biases the outer walls outward. A visual indicator is attached to a distal end of the chamber block and is received in the bore of the barrel and extending outward past the muzzle providing a visual indication that the firearm is in a safe condition. In one embodiment, the chamber block can be inserted into the muzzle and the visual indicator extends through the barrel and chamber and out of the ejection port of magazine well. The visual indicator can be modifiable in length to accommodate various lengths of barrels and can be flexible.
Abstract:
A spray skirt (A) is disclosed for covering the cockpit opening (14) of a kayak (10). The spray skirt includes a fabric cover (24) for spanning the opening which includes an elastic band (B) secured around the perimeter of the cover for retaining the spray skirt about a rim (16) of the opening. The retaining band includes outer and inner elastic bands (30, 32) joined by a compressible bulbous retention element (34, 40). The inner band 32 is of sufficient width to prevent contact of the interior fabric (24b) of the cover from being abraded by lip contact. The preformed outer band (30) includes a first outer band (30a) extending from the bulbous element upwardly and outwardly terminating at a bend (35), and a second outer band (30b) extending from the bend upwardly and inwardly. The first outer band fits under the rim and the second outer band extends over rim and substantially inward over the exterior cover surface to protect the exterior cover surface from abrasion against the rim when hit by the paddle and the like. In a preferred embodiment of the invention, the bulbous element 40 is utilized and has a wall thickness greater than the wall thickness of outer band 42. Preferably, the wall of thickness of the bulbous element is about twice as thick as the wall thickness of the outer band.
Abstract:
A system and method for producing a three-dimensional object (10, 70) from coordinates generated on a computer machine (12) is disclosed wherein the object has improved dimensional accuracy. Control signals (20b) are generated for controlling a servo (20) that controls a reaction or interaction of material (20a) at the coordinate points to form the object while a second servo (22) serves to build up a three-dimensional support system (42) in response to support control signals (22b). Support control signals (22b) are generated at the same time the coordinate points of the design are generated to specify strategic points of the object at which a support environment need be placed in order to insure the dimensional accuracy of the object avoiding warpage or other dimensional distortion. As a support environment, a series of webs (50, 52, 54) or columns (76), or encapsulation (44, 92) may be provided for providing a support environment for the object.
Abstract:
A breakaway cockpit for a kayak is disclosed which includes an egress opening (26) formed in a deck (12) of a kayak hull. An egress panel (28) covers the opening. A cockpit rim (16) surrounding the cockpit opening (14) of the cockpit (18) is interrupted so that a boater may escape from the cockpit through the egress opening. A rim (30) of the egress panel (28) and the rim (16) of the cockpit opening from a composite rim about the entire periphery of the cockpit opening. A sealing strip (34) seals the joint between the egress opening and panel against the entry of water and also assists in retaining the egress panel in place. The egress panel may be popped out by manual force in the event of an emergency so that the boater may escape the cockpit.

Abstract:
A catamaran kayak is disclosed which comprises a plurality of hulls (10, 12) which are joined together and laterally spaced by elongated connectors (B). Flexible couplings (C) are formed on the hulls which receive the ends of elongated connectors (B) and provide for flexibility between the hulls and the elongated connectors in three degrees of freedom. The flexible couplings include flexible bosses (30) which are formed on the kayak hulls and which receive the ends of the elongated connectors. Journals (36) are carried in the flexible bosses and flexible bushings (38) may be carried between the elongated connectors and the journal to control the amount of flexibility provided. This enables flexibility of each flexible coupling (C) to be controlled, if desired, in accordance with the style, weight, and other characteristics of the individual boaters, as well as tailoring the catamaran kayak for the type of water conditions in which it is used. In addition, the flex characteristics of the coupling between the kayaks, and hence the performance of the kayak, may be controlled by the thickness of the hull and the geometry of the hull in the area which the flexible bosses (30) are formed. Preferably, the hulls are molded from a flexible polymeric material and flexible bosses (30) are formed as one piece with the hull.
Abstract:
A watercraft such as a canoe and the like which is propelled by paddling is disclosed that can be paddled on one side and propelled generally in a straight line. The watercraft includes an asymmetrical hull which is asymmetrical along its length and also from side to side. There is a larger volume on one side of the longitudinal center line of the hull than the other. A keel line defined by the bottommost portion of the hull forms a sinuous path from the bow to the stern. For a right handed paddler, the large volume is on the starboard side in the bow section of the hull, and is on the port side in the stern section of the hull. The keel line changes over at a transition section which is symmetrical from the port to the starboard side. The paddling position is slightly aft of the transition section with a paddler properly positioned, the craft may be propelled generally in a straight line by paddling only on the right side, and the craft may be turned left to right by leaning forward and rearward, respectively.
Abstract:
A spray skirt (A) is disclosed for covering the cockpit opening (14) of a kayak (10). The spray skirt includes a fabric cover (24) for spanning the opening which includes an elastic band (B) secured around the perimeter of the cover for retaining the spray skirt about a rim (16) of the opening. The retaining band includes outer and inner elastic bands (30, 32) joined by a compressible bulbous retaining element (34). The bulbous retaining element is rounded and rolls over a lip (18) of the rim and compresses to interlock in a channel (36) beneath the lip. The inner band 32 is of sufficient width to prevent contact of the interior fabric (24b) of the cover from being abraded by lip contact. Upon initial rolling of the retaining element (34) over the lip, the entire retaining band snaps off the rim for quick removal.
