FR2825972A1 - Removable ladder for freeboard of pleasure boat comprises two uprights to which two rounded steps and reinforcing piece are fixed, automatic locking piston being inserted in upper part of each upright - Google Patents

Abstract

The removable ladder comprises two uprights (M1) to which are fixed to two rounded steps (7) and a reinforcing piece (8). An automatic locking piston (5,6) surrounded by a spring is inserted in the upper part of each of the uprights. Each of the locking pistons is attached by means of a small rope (3).

Description

<Desc / Clms Page number 1>

 The present invention relates to a device allowing a person (child or adult) to easily access the deck of a pleasure boat, when the latter is at the foot of its freeboard.

 Access to a boat, when moored to a pontoon, a catway or at anchor (from an annex boat), is difficult given the height of its freeboard. You must be able to lift a very high leg (between 50 to 130 centimeters) to put 1 foot on the edge of the rail or liston of the boat, then hang with your hands on the dies, backstays or handrails of the latter , and finally raise his whole body to find himself standing on the deck of the boat.

To date, there are ladders allowing access with various hanging devices, such as a specific external fastening or a mooring system, but none of these ladders has integrated locking. The present invention overcomes these drawbacks
It is a removable ladder of small dimensions, as well as of low weight in PVC plastic material which is installed at the desired time, on the edge of the deck of the sailboat. The top of this ladder surrounds the section of the fargue or liston rail and its internal curvature comes against the hull. Due to the material used this scale floats.

 This ladder is suspended from the hull and held by a safety device crossing the edge of the fargue, preventing it from coming off the deck by an unfortunate maneuver.

 Figure 1 describes this scale, composed of two uprights (Ml), two steps whose outer edge is rounded (7), a reinforcement (8) stiffening the assembly.

The safety device (Figure 2) is composed of two identical pistons (5,6) manufactured using machined rods (5) with a diameter of 4 to 6 millimeters integrated inside the thickness of each upright ( Ml), and each provided with a return spring (P3). This spring disposed around the rod keeps them closed, and therefore unlock the attachment of the uprights on the rail.

 The end of each rod (6) protrudes from the two uprights (Ml). Each piston is stopped by a threaded nut (P2) in order to hold the spring (P3) inside the uprights.

 These two pistons (5,6) are interconnected by means of a cord (3), which allows the user to install or remove this scale when the time comes with one hand. pose, according to the invention, therefore allows the manipulation of the ladder with one hand, having grasped the cord. In contact with the rail, simply place the ladder on the edge of the rail or liston and pull towards you to open the mechanism of the pistons, thus freeing the passage of the hooking, and letting the reminder be done by itself by Springs.

 For safety reasons the use of the pose and removal of the ladder with one hand, allows ease of installation and freedom of the other hand to hold the boat.

 The ladder thus laid down is held securely against the hull of the so-called freeboard boat.

The usefulness of this ladder consists mainly in accessing in an easy and less restrictive way (taking into account the height of the freeboard) on the deck of a boat from 25 to
60 feet, when it is parked against a pontoon or catway.

 The present invention is multifunctional: - This ladder also allows access to a boat from an annex boat.

 It also serves as an extension for the fixed transom ladder. A so-called bathing kit (Figure 3), consisting of two buckle straps (11) and another sinker (12) make it an extension of the bathing ladder. The two straps are wound around the last bar of the swim ladder of the boat, and connected to the uprights of the invention.

Thanks to its two safety elements (spring pistons), it can remain attached to the fixed bathing ladder of the boat, without detaching alone, and therefore extend by two or three steps (depending on the model). submarine access to the boat.

This ladder can be stored when it is no longer used, in a storage box or hung on the boat dies, because of its safety device, which will make it captive. It can also stand on a flat surface (the steps (7) remaining

 perpendicular to the ground or hang on the edge of a deep box, allowing easier access.

A reinforcement (8) is designed to stiffen the entire construction. The steps (7) are curved and rounded on the outer edge in order to provide a larger surface, and thus better comfort for the foot (whether or not wearing) The internal curvature voluntarily follows the rounding of the free edge of the boat, allowing well to wedge against it and removes any hard angle, to avoid any injury to the user and scratches on the shell.

Claims (5)

1) Removable ladder for freeboard of a boat having a support device characterized in that said support device incorporates a locking device.  2) Ladder according to claim 1 characterized in that the locking device (Fig. 2) consists of an elastic system which prevents against any unexpected opening of the locking system.  3) Ladder according to claim 2 characterized in that the elastic system consists of a rod (5) pushed on a spring (P3), and that said rod crosses the rail of fargue and ensures its locking.  4) Ladder according to claim 1 and 2 characterized in that the elastic system is actuated by a cord (3) allowing the establishment as well as the removal of said ladder with one hand 5) Ladder according to any one of the present claims characterized in that said ladder is made of light plastic materials and allow its flotation
