Abstract
Abstract A boarding step is disclosed for mounting on a towing ring (9) fixedly disposed on the stem (19) of a pleasure craft, for facilitating the stepping into and out of the craft. The boarding step comprises two carrier arms (1) which at their portions (4) which are urged against the craft and have rubber coatings, and which, at their outer ends, are provided with a horizontal tread platform (2). The tread platform has, on its underface, an adjustment rail (5) with a number of alternative pivotal anchorage points (14) for a support strut (6) which, at its end facing the craft, is provided with a pivotal, U-shaped abutment portion (7) urged against the stem (19) of the craft. The support strut has a number of alternative anchorage points (11) for a bolt (10) which also engages with the ring (9) fixed in the stem and which, on tightening, urges the boarding step to a positionally-fixing frictional engagement with the craft. An adjustable stay (15) extends between the carrier arms and the support strut.

Claim 1
Independent Claim
147 words
A boarding step for mounting on a boat comprising, a tread platform; a first abutment member adapted to be in contact with the boat below said platform; a strut member connecting said platform and said first abutment member; a carrier arm connected to said platform and fastening means adapted for fastening said boarding step to a boat, said strut member being connected to said platform by means of first adjustment means thereby permitting the strut member to pivot, said carrier arm having second abutment means adapted for contacting the boat, said carrier arm and said strut member being interconnected by means of a second adjustment means to enable the angular positioning of the strut member and the carrier arm, and said fastening means being connected to the strut member above said first abutment member and adapted to urge said first and second abutment members against a boat.
Claim 2
Dependent Claim
147 words
A boarding step for mounting on a boat comprising, a tread platform; a first abutment member adapted to be in contact with the boat below said platform; a strut member connecting said platform and said first abutment member; a carrier arm connected to said platform and fastening means adapted for fastening said boarding step to a boat, said strut member being connected to said platform by means of first adjustment means thereby permitting the strut member to pivot, said carrier arm having second abutment means adapted for contacting the boat, said carrier arm and said strut member being interconnected by means of a second adjustment means to enable the angular positioning of the strut member and the carrier arm, and said fastening means being connected to the strut member above said first abutment member and adapted to urge said first and second abutment members against a boat.
Claim 3
Dependent Claim
45 words

Claim 6
Dependent Claim
158 words
A boarding step for mounting on a boat comprising, a tread platform; a first abutment member adapted to be in contact with the boat below said platform; a strut member connecting said platform and said first abutment member; carrier means connected to said platform and fastening means adapted for fastening said boarding step to a boat, said strut member being connected to said platform by means of first adjustment means thereby permitting the strut member to pivot, said carrier means comprising two carrier arms, each connected to said platform and each having a second abutment means adapted for contacting a boat, said carrier arms and said strut member being interconnected by means of a second adjustment means to enable the angular positioning of the strut member and the carrier arms, and said fastening means being connected to the strut member above said first abutment member and adapted to urge said first and second abutment members against the boat.
Claim 7
Dependent Claim
158 words
A boarding step for mounting on a boat comprising, a tread platform; a first abutment member adapted to be in contact with the boat below said platform; a strut member connecting said platform and said first abutment member; carrier means connected to said platform and fastening means adapted for fastening said boarding step to a boat, said strut member being connected to said platform by means of first adjustment means thereby permitting the strut member to pivot, said carrier means comprising two carrier arms, each connected to said platform and each having a second abutment means adapted for contacting a boat, said carrier arms and said strut member being interconnected by means of a second adjustment means to enable the angular positioning of the strut member and the carrier arms, and said fastening means being connected to the strut member above said first abutment member and adapted to urge said first and second abutment members against the boat.
Claim 8
Dependent Claim
46 words
