Abstract

(57) [Summary] [Problem] To make it possible to adjust the projecting position of a seat plate from a base plate,
To provide a rudder step for a small boat that can be installed without being restricted by the wall shape of the stern. SOLUTION: A screw of a predetermined length in which a seat plate to be attached to a stern is rotatably connected to a stern at a position opposite to a stern of a base plate on which a person rides so as to be swingable within a certain angle range. Each of the rods is attached, and the length of protrusion of each screw rod can be arbitrarily adjusted according to the wall shape of the stern.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a ladder step used by being attached to the stern of a small boat such as a yacht or a boat.

[0002]

[Prior art]

 The conventional rudder step for small boats has a circular seat plate rotatably connected to both ends of a U-shaped horizontal pipe member provided with a part on which people can ride and hang their feet with pins. It is designed to be fastened to the stern with screws. However, the mounting angle of the seat plate can be changed, but it is not designed to arbitrarily adjust the protruding length from the pipe member.

[0003]

[Problems to be solved by the invention]

 In the conventional rudder steps for small boats described above, since the seat plates provided at both ends of the horizontal pipe member are not configured to move and adjust in the longitudinal direction of the pipe member, the mounting form of the step on the stern wall surface is not sufficient. However, there was a lack of adaptability such as being restricted by the shape of the stern.

An object of the present invention is to provide a rudder step for a small boat in which a step can be installed without being restricted by a wall shape of a stern, by adjusting a projecting position of a seat plate from a base plate. It is in.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the small boat rudder step of the present invention supports the base end of the pipe-made step on the base plate and provides the step so that it can be swiveled, and inverts the step when not in use. In a rudder step for a small boat configured to be held upside down, a seat plate to be attached to the stern is rotatable in a swinging manner within a certain angle range at both ends of the side surface of the base plate facing the stern. It is characterized in that the connected screw rods of a predetermined length are attached to each other, and the projecting length of each screw rod can be adjusted arbitrarily according to the wall shape of the stern.

[0006]

[Actions and effects of the invention]

 When attaching this rudder step to a small boat, adjust the projection length of the screw rod and the direction of the seat plate appropriately according to the wall shape of the stern, and then fix the seat plate to the stern with screws.

[0007] Accordingly, this rudder step for a small boat can be installed without being restricted by the wall shape of the stern by appropriately adjusting the projecting length of the screw rod and the direction of the seat plate. It is convenient.

[Embodiment of the invention]

 An embodiment of the present invention will be described below with reference to the drawings. 1 is a perspective view of a rudder step, FIG. 2 is a plan view, FIG. 3 is a sectional view taken along line AA of FIG. 2, FIG. 4 is a perspective view of a threaded rod, and FIGS. It is a top view explaining the state attached to the stern of FIG.

A rudder step S for a small boat shown in FIG. 1 supports a base end 10a of a substantially U-shaped pipe step 10 on a base plate 1 made of FRP (glass fiber reinforced plastic) by a bracket 11, The step 10 is provided so as to be free to turn. This step 10 is used in a vertical posture with the free end 10b side down, as in the case of the known ladder step, but when not in use, the free end 10b side is turned upside down as shown in FIG. It is configured to hold upside down.

The base plate 1 has a vertical wall 3 integrally formed below the periphery of a substantially square upper surface 2. When the base plate 1 is installed, both ends of a side surface 3 a facing the stern b of the small boat a are provided with screw rods 20 described later. Holes 4 through which the shaft portions 21 pass are provided. Also, one end of the stay 15 is connected to the protruding piece 12 of the bracket 11 protruding from the concave portion 2a of the upper surface 2 to the rear surface by a pin 16. On the free end side of the stay 15, a circular seat plate 17 for attachment to the stern b is provided so as to be rotatable in a swinging manner within a small angle range.

As shown in FIG. 4, the screw rod 20 is provided with a head 22 integrally at one end of a shaft portion 21 having a predetermined length, and a seat plate 23 for attaching the head 22 to the stern b is provided by a pin 24. They are connected so that they can rotate in a swinging manner within a certain angle range. Reference numeral 25 denotes a mounting hole provided in the seat plate 23.

Next, a method of attaching the rudder step S for a small boat having such a configuration will be described. As shown in FIG. 5, after appropriately adjusting the length of the screw rod 20 protruding from the base plate 1 in accordance with the oblique wall shape of the stern b of the small boat a, the nut 26 is fastened to the shaft portion 21. Then, the screw rod 20 is securely fixed to the base plate 1. Then, if each seat plate 23 is fastened and fixed to the stern b with screws, the ladder step S is attached to the stern b. In addition, as shown in FIG. 6, when the wall shape of the stern b is substantially perpendicular to the center of the boat, the threaded rod 20 may be mounted with the projecting length of the same size.

As described above, the rudder step for a small boat can be installed without being restricted by the wall shape of the stern by adjusting the projecting position and the direction of the seat plate from the base plate. It is very convenient.
