Abstract: Ladder configurations and components are provided including an outer rail assembly which is longitudinally adjustable relative to an inner rail assembly. The outer rail assembly may include a pair of spaced apart outer rails each fixedly coupled to an associated sleeve or sliding mechanism. Each sleeve is in turn slidably coupled to an inner rail of the inner rail assembly. The outer rails may be positioned and oriented at an acute angle relative to the inner rails so as to provide an increased base distance between the two outer rails. Support structures are also disclosed which are coupled at multiple locations along a rail member and at least one location of a rung. Additionally, ladder hinges are disclosed including hinge components configured to effectively transmit loads from associated rails. In one embodiment the hinge may include a pinch prevention mechanism.

Abstract: A trunnion, adapted to fit in a receiver, attached to a vehicle as a receiver-type hitch system, provides selective deployment and stowage of a hitch. An optional base secured to the trunnion may receive a pivot. A mount, secured by the pivot to the base, swings between a deployed and a stowed position. Alignments are one-dimensional, typically circumferentially positioning a locking pin aperture and a corresponding locking pin about a radius with respect to a pivot axis. A platform of the mount may contain an aperture for operating as a pin hitch aperture or for receiving a stud or bolt for securing a ball hitch or two hitches. In certain embodiments, multiple ball hitches may be attached at once to the platform. Selection of ball hitch sizes and positioning of the ball hitch altitude may also be accomplished by pivots built into the mount.

Abstract: A method for manufacturing a rail for a ladder. The method may include pultruding in a longitudinal direction, a rail having a selected cross-sectional shape. The rail may then be cut to a predetermined length at a distal end. A force may be applied, in a lateral direction, to the rail to form a curvature therein. The curvature may be characterized by a flared portion, a straight portion, and a curved region providing the transition therebetween. The rail may be held at the desired curvature for a time selected for the rail to take on the curvature substantially permanently. The force may then be removed and the rail may be assembled into a ladder.

Abstract: An apparatus for mounting a hitch to a vehicle. The apparatus may include a base connected to the vehicle. A mount, having a fastening portion and a main portion, may also be included. The fastening portion may receive a plurality of hitches thereon. The main portion may pivotably engage the base to provide a pivoting motion of the mount with respect to the base between a stowed position and a towing position distinct from the stowed position. A pivot may connect the main portion to the fastening portion to provide rotation therebetween. The apparatus may also include a hitch system having a first ball hitch monolithically formed to have a shank. A second hitch may be monolithically formed to have an aperture therein. The aperture of the second ball hitch may be shaped to axially receive and engage the shank of the first ball hitch.

Abstract: A hitch for presenting different sized ball hitches for towing use. The hitch may include a first ball and pedestal extending in a first direction. A second ball and pedestal may extend in a second direction, distinct from the first direction. The first ball and pedestal and the second ball and pedestal may be homogenously formed of a single material to form a monolith. A stem may connect to the monolith to support and present the first ball and pedestal and the second ball and pedestal for towing use. The stem may extend away from the monolith in a third direction, distinct from both the first and second directions.

Abstract: An apparatus for securing a towing vehicle to a towed vehicle is disclosed. The apparatus includes a base, a mount movably secured to the base and one or more hitches attached to the mount. The mount may rotate, pivot, translate, or otherwise move in relation to the base in order to move the hitch between various positions including one or more towing positions and at least one stored or stowed position. The hitch, or hitches, may also be movably secured to the mount for additional flexibility in configuring the apparatus in the towing and stowed positions. Additionally, when multiple hitches are provided, each of the multiple hitches may be configured as different size or style of hitch such that a user may select one of the hitches depending on the intended use thereof.

Abstract: A towing apparatus is provided including, in one embodiment, a pintle hitch having a retainer and an associated retainer lock. The retainer may be coupled with a mount by way of a pivot allowing it to rotate into and out one or more selected positions. The retainer may also be mounted on a guide such that it may translate relative to a mount. The apparatus may be configured to be selectively displaced between a towing position and a stowed position. Additionally, the mount of the apparatus may be adjustably coupled with the base. In such a case, the apparatus may have another guide to enable the mount to translate relative to the base. This may allow the mount to be height-adjustable and provide further versatility. In one embodiment, a swiveling mount may allow the mount to swivel relative to the base to accommodate the towing of trailers over rugged terrain.
