Abstract: A latch mechanism for a fifth wheel hitch that automatically closes a jaw and locks the hitch when the hitch engages a kingpin. The latch mechanism includes a handle that is used set the latch for receiving the kingpin. The latch mechanism also includes a latching member that is biased toward a closed position and tripped in response to engagement of the kingpin with a jaw.

Abstract: A golf bunker rake has a coupling member adapted to receive a support. First teeth are connected to the support and have substantially round first tips. Second teeth are connected to the support and have substantially round second tips. The first teeth are longer than the second teeth. The rounded tips of the first teeth prevent damage to the golf bunker liner during use.

Each upright assembly includes a lower sleeve portion for receiving a respective guide rail, an intermediate housing portion vertically above the sleeve portion, and an upper mounting portion vertically above the housing portion. A head assembly may be adjustably mounted between respective housing portions of the upright assemblies. At least one roller is positioned within each housing portion of the upright assemblies such that the at least one roller contacts an upper surface of an upper guide rail. In addition, the glider fifth wheel attachment assembly includes a latching assembly for releasably locking the glider fifth wheel attachment assembly between a first and a second position.

Abstract: An underbed gooseneck hitch assembly includes a channel housing that is secured to a pair of angle brackets. The angle brackets are secured to a pair of frame mounting brackets, which are in turn mounted to the frame rails of the vehicle. The hitch assembly also includes a ball socket for receiving a ball hitch. A pull cable handle assembly includes a spring biased retaining pin that can be retracted from and inserted into the ball hitch to secure the ball hitch for use. The ball hitch protrudes above the cargo bed and is attachable to a gooseneck trailer. Insertion of the ball hitch is accomplished by turning the handle of the pull cable handle assembly to an unlocked position, rotating the handle to a locked position, and inserting the ball hitch into the ball socket. The ball hitch is properly aligned with the retaining pin by inserting the ball hitch completely into the ball socket and aligning indicia on the ball hitch with a notch on the ball socket.

Abstract: An under-bed mounting system installed beneath a cargo bed floor of a vehicle includes both a male pin and a female receptacle. A releasable locking mechanism is defined between the pin and the receptacle to permit installation and removal of desired components such as a fifth wheel hitch. The pin including opposing first and second ends and an intermediate portion, a groove being disposed within said intermediate portion and including a stem and a base portion. A portion of the receptacle is received within said groove, selectively contacting said stem during installation and contacting at least the base portion after said installation. In one embodiment, the groove of the pin is generally L-shaped, the receptacle including a rod that is selectively received in the groove. In a second embodiment the pin is a scissor clamp with opposing jaws pivotable about a common hinge. The jaws engage the inner periphery of the receptacle.

Abstract: A liner for a manhole, inspection chamber or the like comprises one or more sections moulded from synthetic plastics material. The or each section comprises inner and outer skins (2,3) joined together by two series of webs (4,7) extending between and at right angles to the skins (2,3). The webs (4) are disposed at the upper edges (5,6,) of the section and the webs (7) extend between a position below those upper edges (5,6) and a position at its lower end. The upper edges (5,6) and lower periphery (9) of each section are formed so that superposed sections interlock. The arrangement provides an easily installable corrosion resistant load bearing yet light, rigid and deformation resisting structure.

Abstract: A trailer hitch assembly includes an interchangeable ball having a first bore for removably receiving a stub shaft attached to the towing vehicle. Both the ball and stub shaft have transverse bores that can be aligned with one another to receive a removable pin for securing the ball to the stub shaft during normal use. When the ball is not on the stub shaft, a clip can be inserted into the first bore of the ball to removably engage the pin and prevent the pin from being withdrawn from the ball. This feature helps to prevent the pin from becoming lost or misplaced while the ball is in storage.

Abstract: An apparatus is provided that is suitable for securing an article (e.g., a spare tire and wheel assembly) suspended in an elevated position underneath a support article (e.g., a vehicle) by a resilient support member. The apparatus includes a stationary bracket, outer and inner members, a compression spring, and a catch member. The stationary bracket is connected to the support article and includes a retaining formation. The outer member includes a passageway, an inner seating surface, and at least one slot-like formation. The inner member, which includes an end surface, is telescopingly received within the outer member and is connected to the resilient support member. The compression spring is positioned between the inner seating surface of the outer member and the end surface of the inner member and biases the inner and outer members with respect to one another.

Abstract: A cam assembly for a hoist mechanism includes a cam member, a pair of springs and an input shaft. The cam member has a cavity defined by an inner periphery of a side wall and floor. Cutout portions extend radially outwardly from the inner periphery of the cavity. The springs include a bow-shaped body portion positioned between first and second connection end members. The body portion further includes an outwardly extending detent, each detent extends into a cutout of the cam member to operatively connect the cam member to the springs. The input shaft has a through hole. The first connection end members of each spring are inserted into the through holes of the input shaft, thereby operatively connecting the springs to the input shaft with a reduced number of components.

Abstract: A device for eliminating rattle in a receiver-type hitch due to movement between hitch components includes a collar, an adjustment bolt, a lock nut and a second nut. The collar has a center wall and two side walls forming a U-shaped bracket that can fit over a reinforcing lip of the hitch receiver tube. A front wall on the collar has an opening for receiving a mount shank as it enters the receiver tube. An adjustment bolt extends through the center wall to tighten the collar onto the hitch receiver tube. When the adjustment bolt is tightened, the center wall of the collar moves away upward away from the receiver tube, causing the opening in the front wall to lift the shank against the inner wall of the tube and prevent it from moving within the tube. The lock nut then holds the entire anti-rattle assembly into position. Thus, the anti-rattle device prevents hitch rattling with a minimum of components.

Abstract: A ball assembly is intended to be mounted on a stem of a tow vehicle, and to be used in conjunction with a hitch portion of a trailer hitch assembly. The ball assembly, generally, includes a body member which is substantially spherical in shape, the body member having a partial bore formed substantially vertically therein for receiving a stem of a towing vehicle therein, the body member further having first and second transverse registering apertures formed therethrough. The ball assembly also includes a locking pin which is slidably movable in the registering apertures of the body member, and structure for connecting the pin to the body member. In a preferred embodiment, the connecting structure includes an enlarged shoulder portion on the pin, and a stop member disposed in the first transverse aperture of the body member, the stop member preventing the shoulder portion from moving therepast.

Abstract: A method and apparatus for mounting a trailer ball to a mounting platform. The apparatus includes a trailer ball having a threaded stem, a flat washer, and a nut having a plastic collar. The plastic collar includes a ring which is disposed between the nut and flat washer. The ring is formed of a plastic material which is extruded when the nut is tightened sufficiently to provide a positive indication that sufficient tension has been placed on the joint. The method also includes lubricating the stem before threading the nut onto the stem and removing the extruded ring after tightening.
