  • Patent number: 11302297
    Abstract: A removable and reversible sliding mount for a marine transducer has a C-shaped mounting channel affixed to the transom of a boat. A closed bottom end of the C-shaped mounting channel is proximal to the bottom of the boat and an open top end of the mounting channel is at or above the water line of the boat. A mounting board having a handle at one end and a transducer at the other end may be slid into the mounting channel so that the transducer is positioned just below the bottom of the boat. The mounting board may in be inverted so that the transducer is positioned above the waterline of the boat. A locking mechanism may be used to secure the mounting board in the mounting channel. The mounting board may also include cable guides to secure a transducer cable along its length.

  • Patent number: 9447638
    Abstract: An access device that provides access between a substrate surface and an elevated surface includes a first ladder member that is operatively attached to a mounting via a drive mechanism. The drive mechanism includes a rotatable member having three pivotal connectors spaced apart in a triangular arrangement. A first of the connectors is pivotally attached to the mounting. A second of the connectors is pivotally attached to the first ladder member via a control arm. A third of the connectors is pivotally attached to an extremity of the mounting via an extendible arm. The extendible arm causes the rotatable member to rotate about the first connector, and consequently effect movement of the access device. The access device further includes a second ladder member, a first end of which is pivotally attached to a second end of the first ladder member.

A linkage assembly connects the ladder assembly with a mounting plate connected with the tailgate. The linkage assembly spaces the ladder assembly from the tailgate when the ladder assembly is in the operable condition, allows the angle of the ladder assembly relative to the tailgate to vary in accordance with the height of the tailgate relative to the ground, and prevents the ladder assembly from pivoting past a normal position relative to the ground. A handle is also pivotally connected with a side wall of the truck adjacent to the tailgate to assist a user with climbing the ladder assembly into the bed of the truck.

  • Patent number: 7090049
    Abstract: The aquatic ladder was designed for ease of use, rather than ease of storage. It has wide, deep treads, arranged like a staircase, with side and upper railings which make it easy to enter or exit the water, even by elderly people, tired individuals, those carrying aquatic equipment, such as SCUBA gear or water skis, and, even, by pets. In the preferred embodiment, the aquatic ladder includes upper railings which each have an inverted “U” shape, and the distal end of those railings have hinged brackets for mounting the aquatic ladder to an object to be boarded. In an alternative embodiment, the aquatic ladder is mounted on a sliding rail, such that it can be raised, vertically, from the water, when it is not being used. The ladder is preferably made from aluminum, although it can be made of other materials, such as steel (e.g., stainless or galvanized), fiberglass, plastic, or other composites.

  • Patent number: 7080713
    Abstract: A ladder assembly including a mounting system and a ladder that is adapted to be pivotally attached to a vehicle such as the tailgate of a truck bed. When the tailgate is opened, the ladder can be pivoted away from the vehicle bed to a substantially perpendicular position with respect to the tailgate or its original orientation. Following, the lower end of the ladder is adapted to pivot downwardly such that the lower end of the tailgate contacts the ground surface. The ladder is further pivotable about a second pivot member in a lateral manner such that the lower ends of the support legs of the tailgate ladder contact the ground depending on the slope of the ground surface.

  • Patent number: 7017709
    Abstract: A buoyant marine safety ladder apparatus includes a ladder that is pivotably mounted to a seawall or other support platform and is alternatable between a retracted condition, wherein the ladder is floating above the water, and a deployed or extended condition, wherein the lower end of the ladder extends into the water. A stop component restricts pivoting of the ladder such that it extends upwardly from the body of water at an angle of approximately 45° when in the extended condition.

  • Patent number: 6994184
    Abstract: A folding ladder is configured for installation in an opening to provide access between one floor or space and another floor or space. The folding ladder includes, in one aspect, an upper ladder section having a left ladder rail and a right ladder rail, a lower ladder section having a left ladder rail and a right ladder rail, a hinge rotatably connecting the upper ladder section ladder rails to the lower ladder section ladder rails, and a plurality of steps rotatably disposed between the upper and lower ladder rails. The plurality of steps are configured for rotation between a retracted position and a deployed position. At least one step disposed between the upper ladder rails and at least one step disposed between the lower ladder rails are linked by at least one linkage member so that each of the noted steps rotates between a retracted position and a deployed position upon rotational movement of the upper ladder section relative to the lower ladder section between a closed position and an open position.

  • Patent number: 6986402
    Abstract: An access device for providing access between a lower substrate surface and an upper substrate surface. The access device includes upper and lower articulated ladder members. A first end of the upper member is pivotally connected to or near the upper surface. A second end of the lower member is pivotally connected to the second end of the upper member, such that the lower ladder member is rotatable 180° relative to the upper member. In the storage position, the ladder members are folded in a substantially compact upright disposition, while, in the access position, the members are aligned and extend downwardly and outwardly.

  • Patent number: 6948588
    Abstract: A ladder system through which a ladder is retained on a deck of a watercraft by a track arrangement and positioned at a first location in an opening for an enclosure where the ladder is substantially vertical to the side of the watercraft to permit ingress/egress of a person between a body of water and the deck. The ladder is connected to a rail of the track arrangement by a first and second hinges that permits the ladder to be rotated from the vertical position along the side of the watercraft to a position inside of the enclosure. The ladder may thereafter be moved from the opening to a location adjacent the gate and behind the enclosure to conceal and stow the ladder such that the exterior surface of the watercraft along the enclosure is substantially uniform from stem to stern.

    Abstract: A bracket to hold a boarding ladder to a boat. A quick release mechanism for both the ladder and the bracket itself are disclosed. A mounting plate is substantially flush with the side of the boat. The bracket slides down into the mounting plate and latches into place. The bracket accepts the upper bar of a boarding ladder and closes a latch over the bar, holding the ladder in place. To remove the ladder, a latch at the top of the bracket is lifted and the ladder can be easily pulled free. To free the bracket from the mounting plate after the ladder has been removed, the latch is lifted and the bracket can be lifted out.
