Description

The utility model relates to the field of shipbuilding, in particular to the designs of steering devices for small vessels of various purposes with rudder lifting feathers.

In the process of operating various sailing ships, one of the most significant nodes is the steering device. The safety of the vessel and crew depends on its reliability, convenience and ease of use.

In the design of small vessels, a certain tradition has developed in the design of steering devices. The tiller is used for manual installation of the rudder feather at the required angle to the longitudinal axis of the vessel, if necessary, turn. The pen has the ability to rotate in a vertical plane inside its box from the working position (vertically down) to the parking position (horizontal) and vice versa. When hitting an underwater obstacle or the bottom of a reservoir in the working position, the feather of the steering device must be raised to avoid damage to the mechanism, however, it should not be raised due to the oncoming flow of water that occurs when the vessel is moving.

There are various ways to control the position of the pen for moving the device from the parking position to the working position and vice versa (raising and lowering the steering wheel), for example, directly with the helmsman’s hand, using rope rods, etc.

The prior art knows, for example, a mechanism for raising the rudder feather, comprising a baller, a tiller pivotally mounted at the top of the baller, a rudder feather and two latches, one of which serves as a stopper, and the other is a lift, controlled by raising the steering wheel with the tiller, and when lowering the rudder - by traction (see M. Karnitsky et al. “Mechanism for raising the rudder feather”, collection “Boats and Yachts”, issue 3 (85), p.41). The disadvantage of this design of the mechanism for raising the steering wheel is the lack of a rigid kinematic connection between the tiller and the feather of the steering wheel and the presence of a large

the number of connecting parts, which makes it difficult to use the design.

Closest to the proposed one is the steering device of a sailing vessel, taken as a prototype, containing a box of a rudder pen, lower and upper loops of a rudder suspension, a tiller and a rope to control a rudder feather, while the axis of the rudder feather is fixed in the upper part of the box, and in the lower suspension loop horizontal cutouts are made, into which the rudder feather pin enters with the possibility of fixing in the indicated cutouts when the rudder feather is lowered. One end of the rope is fixed to the steering wheel overhead, and the other through the blocks that the rudder's feather box is equipped with, is brought out to the tiller (see ed. Certificate of the USSR No. 1240684, class. 63 N 25/08, 1983).

The disadvantage of this device is the complexity of the control, the impossibility of reliable fixation of the rudder feather in extreme positions, as well as the emergency return of the control cable of the rudder feather when the latter touches an obstacle, which reduces the operational characteristics of the device.

The objective of the proposed utility model is to simplify and accelerate the control of raising and lowering the rudder feather, which leads to an increase in crew safety and the comfort of a vessel equipped with such a device.

The problem is solved due to the fact that in the steering device containing the steering wheel feather, mounted on an axis in the pen box with the possibility of rotation in the vertical plane, and the tiller associated with the steering wheel feather, the tiller is preferably made double, both of which are placed on the outside pen boxes and are connected to the rudder feather by an axis, the device contains a spring or springs fixed on the same end of the tiller (at the ends of the twin tiller) and on the pen box (on both sides of it), as well as a thrust roller mounted on the pen box but with the ability to interact with the tiller.

A pen box is mounted on the stern of the vessel using horizontal swivel hinges.

In Fig.1 - 3 shows a diagram of the operation of the device, while in Fig.1 - with the position of the rudder feather in the operating position (lower), Fig.2 - in the horizontal position, Fig.3 - in the parking position (vertically up) .

The steering device consists of a rudder feather 1 mounted on an axis 2 in a pen box 3 mounted on the stern of the vessel 4 using hinges 5 of steering rotation. Both parts of the double tiller 6 are placed on the outer sides of the pen box 3 and are connected to the pen 1 through the axis of rotation 7. At the ends of both parts of the twin tiller 6 are fixed springs 8, attached externally to the box 3 of the pen in its lower part on both its sides. A thrust roller 9 is installed in the upper part of the pen box 3.

In the working position of the rudder 1 pen (lower), the vessel is controlled through the dual tiller 6, as when using a standard steering device.

The rudder feather 1 is not tipped off by the oncoming flow of water when the vessel is moving, thanks to the installed springs 8, however, when hitting an underwater obstacle or the bottom of the reservoir, feather 1 is deflected, stretching the springs 8, and absorb shock.

If it is necessary to raise the rudder feather 1 to the parking position (vertically upward), the steering force abruptly presses the front end of the tiller 6. The tiller 6 abuts against the thrust roller 9 and rotates the rudder feather 1 in box 3, and stretches the springs 8. In the upper position of the feather 1 rudder springs 8 prevent the lowering of the pen 1 in the working position (lower).

To lower feather 1 of the steering wheel from the parking position (vertically up) to the working position (lower), the steering sharp movement down, similar to what is necessary to raise feather 1, press

the front end of the tiller 6. The tiller 6 abuts against the thrust roller 9 and rotates the feather 1 of the steering wheel in the box 3, stretching the springs 8. When compressing the springs 9, feather 1 occupies the working (lower) position.

The ease of raising and lowering the steering wheel allows the helmsman not to be distracted from the control of the vessel. This steering gear has been tested and is suitable for installation and operation on various types of small vessels.
