Abstract: A metal post support ground spike is disclosed having a post receiving socket, and a flat plate. The flat plate is welded to four walls of the post receiving socket. The post support may also comprise a blades portion welded to the flat plate. The blades portion, post receiving socket and flat plate may all have reinforcement lines stamped therein and may comprise metals of varying thickness and rigidity. The flat plate may comprise the thickest and most rigid metal, whereas the post receiving socket and/or the blades may be made from a thinner and/or less rigid metal.

Abstract: An assembly for rapid loading and feeding of paintballs in a paintball marker comprises a receiver mountable on the marker, having an opening to receive and secure a magazine carrying paintballs, and a gate opening mechanism to open the magazine, releasing the paintballs. An ejection mechanism to clear a magazine from the opening may also be provided. The magazine comprises a resiliently biased gate mechanism to protect the paintballs until the magazine is inserted into the receiver. The magazine may be opened to refill it with paintballs, and may be disassembled for cleaning or maintenance.

Abstract: An electric vehicle includes a chassis and a compartment defined by the chassis. A power container houses at least one energy storage/generating device for powering the electric vehicle. The power container is insertable into and removable from the compartment through the left side and the right side of the chassis. A suspension apparatus includes a shaft, a control arm pivotably connected to the shaft, at least one helical torsion spring mounted on the shaft, and a linear actuator. Movement of the linear actuator increases bending stress on the at least one helical torsion spring and urges the control arm downwardly.

Abstract: An exercise strap comprises an upper strap and a lower strap. A plurality of loop members are located on the lower strap to allow for handles to be easily removed and replaced on different locations on the lower strap. An adjustment member attached to both the upper strap and the lower strap allows for the overall length of the exercise strap to be adjusted. A strap attachment member attached to the upper strap connects the exercise strap to a suitable mounting mechanism.

Abstract: The invention provides an insert assembly to convert an existing fireplace hearth into a gas burning fireplace and a method for installing the insert assembly while conveying the appearance of a wood burning fireplace. The insert assembly comprises legs removably attachable to the base of the firebox for allowing the insert to be installed higher into the hearth. The inner walls of the firebox are colored so as to camouflage the structure of the assembly in the hearth and a decorative fender mimics a wood burning grill. Where the insert includes a heat exchanger, a guide plate is provided at the top of the insert to ensure that air exiting the heat exchange outlet at the top of the insert is directed into the room.

Abstract: This invention relates to a novel method and a novel inflatable flotation device for the method which are used in association with water sports boards such as kite boards, surfboards and the like, for the purpose of uprighting the water sports boards when inverted and encouraging the water sports boards to be moved by the wind in the direction of a water sports board rider when the rider becomes separated from the water sports board.

Abstract: An improved crustacean, fish & animal trap comprising a collapsible hoop and mesh structure to minimize storage size. The invention is unique in that it collapses through the manipulation of flexible hoops to a size minimized in all three dimensions. The primary configurations would be for crab, prawns and lobster/crayfish; however, in slightly different configurations, can be used to catch or cage animals, fish and other crustaceans. Another embodiment of the trap would feature only one hoop and would be used as a “lift trap.

Abstract: An attachable and detachable handgrip, primarily used with plastic bags, canvas bags and other items with handles, is disclosed. The attachable handgrip comprises a single piece of flat, pliable material that will hold its shape, yet yield easily to force. The material is rolled upon itself to form a spiral structure. Once formed, the handgrip is attached to the bag handles by placing the bag handles in the longitudinal slit formed along an edge of the spiral structure and rotating the spiral structure until the bag handles are within the spiral structure.

Abstract: The present invention discloses a zipline trolley comprising of two substantially flat side flanges arranged in a parallel configuration, a substantially flat front face attached perpendicularly to the front edges of the side flanges, and a substantially flat back face attached perpendicularly to the rear edges of the side flanges. There are also provided two axles for bearing wheels and four lines for attaching the side flanges to the two spreaders. One set of two lines is attached to the bottom of each of the side flanges. The lines are connected to two spreaders, which are attached to the ends of a handlebar.

Abstract: An underreamer for well drilling comprises pivotally extendible roller cutters that extend slightly beyond the diameter of the pilot drill bit but are retained in their retracted position by the casing. Upon encountering an obstruction, the underreamer is pushed out of the casing, allowing the outer edges of the cutters to contact the obstruction. Continued downward pressure of the drill stem causes the roller arms to pivot outward to a fully extended position in which the cutters enlarge the hole to a diameter larger than the casing by rotation of the drilling stem. The advance of the casing relative to the underreamer forces the cutters to retract into the casing.

Abstract: An extrusion mold head is provided having outer mold tapered cams that form an automatically contracting or expanding mold surface during extrusion of the poles, allowing the formation of tapered outer diameter on each pole. The extrusion mold head also has an inner mold tapered mandrel that is advanced or withdrawn in concert with the movement of the outer mold head pieces. The inner mold surface thereby automatically contracts or expands as required during extrusion of the poles to form either a uniform thickness or a tapering thickness of the wall of each pole.

Abstract: A protective body guard (10) providing a full range of motion that closely tracks the biomechanical movement of a joint. The device provides protection against sharp objects, impact and limb movement into positions that may cause injury. The device (10) comprises successive segments (12, 14, 16, 18, 20, 22) made of a hard, impact-resistant, light material and arranged in overlapping fashion and interconnected by means of a single pivot pin (28) or flexible strap in an arcuate slot (30) at each side of the segments. Cushioning pads (24, 26), detachably fixed to the segments (12, 22), provide protection from contact with the interior of the segments.
