Abstract: A mechanism for stabilizing a slidably adjustable boat accessory such as a boat seat or table including a first rigid plate member adapted for attachment to the underside of a boat accessory, a second rigid plate member adapted for attachment to a support surface with the first plate member having two elongate opposite side edges curved underside forming parallel tracks and the second plate member having two elongate opposite side edges slidably engaging corresponding respective tracks of the first plate member for slidably moving the first plate member along the tracks for slidably adjusting the location of an attached boat accessory with at least one of the opposing side edges of the second plate member beveled at least in part, a wedge shaped member engaged with the second plate member resting in part on the bevel, while adjustably moving the wedge shaped member along the bevel such that the wedge shaped member is moved laterally in its associated track.

Abstract: For removably coupling a boat apparatus, such as a boat seat or table, to a boat deck, a base plate having a clamping slot is attached to the boat deck and the boat seat or table or the like is supported by a base assembly having a clamping bolt. The base assembly is placed over the base plate with the clamping bolt engaged in the clamping slot and a manually operable member on the base assembly is manually operated to releasably clamp the bolt securely in place in the associated slot.

Abstract: For removably coupling a boat apparatus, such as a boat table or seat, to a boat deck, a base plate having an arcuate or curved clamping slot is attached to the boat deck and the table or the like is securely coupled to a base assembly having a downward extending clamping device. The base assembly is placed on the base plate with the clamping device engaged in the clamping slot and the base assembly is then twisted or turned so that the clamping device slides to the end of the slot and a member on the base assembly is then manually operated to releasably clamp the clamping device securely in place in the associated slot.

Abstract: A bracket is attachable to the side of a boat or dock and a latch is removably coupled to said bracket. The latch is pivotally attached to the upper end of a boat ladder so that the ladder can swing and can be adjustably angled with respect to the dock or boat when it is latched onto the bracket.

Abstract: A bracket is attachable to the top surface of a rigid support platform, such as a boat deck or dock, and a latch member is removably coupled to the bracket at about one end of the latch member and extends out beyond the edge of the platform and the latch member has a pivot pin at its outer end for pivotably engaging a boarding ladder.

Abstract: A boat seat is rotatably supported on a hollow, tubular, deck-mounted support post or column by a yoke or spider. A radially movable locking plate is biased by a spring member to rotatably lock the yoke in place and a lever arm can be operated to move the locking plate in opposition to the force of the spring member out of locking engagement to permit the seat to be rotatably adjusted.

Abstract: A boat ladder has a rigid I-beam support with steps pivotally attached for making the ladder compact, with the ladder pivotally engaged with a compartment in the boat hull for storing the ladder when not in use.

Abstract: A ladder which is particularly useful as a boat ladder is constructed with a pair of centrally located side-by-side elongated support members which are movable lengthwise, to a limited degree, with respect to one another. The ladder rungs are pivotally attached to the support members such that when one support member is moved lengthwise the rungs are swung to extend outward from the support members for use as a stepping ladder and swung inward to be in line with the support members to make the ladder compact for storage. The ladder is pivotably engageable with a storage compartment in a boat hull for swinging the ladder downward for use from an opening in the compartment and upward in line with the opening for insertion into the compartment for storage.

Abstract: A vertically adjustable pedestal for a boat accessory such as a table or seat is made up of a pair of telescoped tubular members having opposite facing lengthwise recesses which contain rods to allow one member to adjustably slide with respect to the other yet preventing rotation. A releasable locking device holds the adjusted member at its desired elevation.

Abstract: A boat seat is mounted on two sets of slidably engaged members for slidably adjusting the location of the boat seat front and back with a locking mechanism for holding the seat at its adjusted location comprising a locking pin for engaging detent holes controlled by a lever arm extending out the front of and below the boat seat.

Abstract: A boat seat is pivotably hingedly attached along a line parallel to its front edge to a supporting member spaced below the boat seat with shock-absorbing resilient padding located in the spacing between the underside of the boat seat and the supporting member. Preferably the padding is slidably adjustable and also can be removed and replaced with padding of different durometers as necessary for differing conditions.

Abstract: For a slidably adjustable boat seat or table top, a first plate member for carrying a seat or table top has a pair of underside tracks along parallel outer edges which are slidably engaged or mated with edges of a supporting plate member. One edge of the supporting plate has a series of recesses and there is a cam toothed rod mounted in the mating track which is rotatably spring-biased to rotate the rod to bring the teeth and the recesses into engagement to lock the plates together and a lever handle attached to the rod is provided to manually rotate the rod to disengage the teeth for slidably adjusting the seat position.

Abstract: A boat seat is rotatably supported on a tubular deck-mounted support post or column by a yoke having an annular extension engaging said tubular support. A locking plate having ridges or teeth for engaging slots on the exterior of the tubular support is mounted on the yoke and is selectively movable into locking engagement with said slots by a lever arm to positively prevent rotation of the boat seat. A spring biases the locking plate out of locking engagement when the lever arm is moved to the unlock position.

Abstract: A roof snow rake blade has a spacer, preferably in the form of a roller, attached at its bottom edge to space the bottom edge away from the roofing while not interfering with the normal snow-removal function of the blade.

Abstract: A weight-supporting walking aid has two side supports joined at the front to a crossmember by couplings which permit the side supports to be folded inward over the crossmember for storage and latch the side supports in the open position for normal use.
