The grinders enable transfer of rotation of a crank drive to a drive train (3) of the winch. The hydraulic pump is driven over the former grinder (4) by actuating a clutch (6), so that hydraulic liquid is pressurized to be removed from the reservoir. A hydraulic motor (11) is provided in the region of the drive train to support the rotation of the drive train and the winch only if necessary.

Description

The The invention relates to a device for operating rope Sailing vessel, comprising at least one winch for transmission of tensile forces on the cordage and a hydraulic pump for filling a memory.

in the Range of sailing ships, especially on larger ones Sailboats, usually come in the form of winches Winches for operating ropes, such as pods, traps and others Ropes, used, over which in the to be operated Rope tensile forces can be initiated. in this connection This rope is with a few turns around a drum of the rope Winch placed, which can be operated with a hand crank. A Rotation of the winch drum is only possible in the tension direction, while an opposite direction of rotation through within the drum arranged pawls is prevented.

at In addition, big regatta yachts with lots of winches will be added often called grinders, vertical columns with crank drives, used to target the individual winches operate and control from central points. One by the Crank drives generated rotary motion of each grinder is about a timing belt or similar system on a drive train transferred inside the boat and over this directed to the desired winches. Often can the relevant grinder on clutches targeted with the Powertrain, which makes it possible to by connecting several grinders together targeted individual winches to use.

From the EP 1 650 124 A1 Such a device for operating rope of a sailing ship is known, in which a winch by means of a grinder is operable. For this purpose, a rotary motion can be generated on a crank drive of the grinder and transmitted by means of a toothed belt to a running inside the boat drive train, which is connected via an angular gear with an input shaft of the winch. Between the drive train and the grinder also a clutch is provided, which can be operated by foot pedals in the grinder.

disadvantageous on such a system, however, is that the operators of the grinder the force required to operate the drive train and in the course of the winch in full independently have to raise. In some sailing maneuvers are However, very high tensile forces on the winches in as possible a short time, which is a significant burden represents the sailing crew.

The WO 79/00932 further discloses an operating device for cordage of a sailing ship in which a winch and a pump-motor unit are operable via a hand crank. Two operating modes of the pump-motor unit can be set via a control unit, the unit acting as a pump in a first operating mode and, inter alia, filling a reservoir with pressurized hydraulic fluid. By switching to a second operating mode, however, the pump-motor unit acts as the drive motor of the winch, with the necessary, pressurized hydraulic fluid is removed from the memory.

One However, such system knows the considerable disadvantage on that one filling of the memory in the first operating mode the device only at times of operation of the winch over the hand crank can take place, as the hand crank and winch are firmly together keep in touch. But this also means that the operator the hand crank next to the necessary for operating the rope Force also an additional force to operate the pump and filling the memory must apply what represents a higher burden.

It Therefore, the object of the present invention is a device to provide rope rope to a sailing ship, in which a filling of a memory via a hydraulic pump to Supporting the drive of a winch is provided this filling in maneuver-free sailing phases, So not simultaneous operation of the winch can take place.

These The object is based on the preamble of claim 1 in conjunction solved with its characterizing features. The following, dependent claims give each advantageous Further developments of the invention.

The invention comprises the technical teaching that a grinder is provided for operating the winch, in which a rotation can be generated by a crank drive and, for example, via a toothed belt to a drive train of the winch transferable, by actuation of a clutch, the hydraulic pump is driven via the grinder , The then supplied by the hydraulic pump in the memory, pressurized hydraulic fluid can then be supplied to a provided in the drive train hydraulic motor to assist the rotational movement of the drive train and thus the at least one winch if necessary. Since a filling of the memory only takes place when the clutch is operated via the grinder, this filling can be used in maneuver-free sailing phases or on a grinder that is not currently being used to operate a winch will be performed.

According to one Embodiment of the invention is between memory and Hydraulic motor and in the drive train a servo unit provided by the voltage applied to the drive train through torque a measuring device determined and in case of need under pressure Hydraulic fluid to the hydraulic motor passes. By providing A servo unit in the area of the drive train can do this on the drive train adjoining moment are determined and thus a supply of the Hydraulic motor easily controlled and timed limited to which operation of the winch over the drive train takes place.

In Further development of the invention is the measuring device in the manner of a Torsion-torque measurement built. This has the advantage that a For example, sensor technology determination of the powertrain applied torque in a simple and reliable way and can be done. Such servo units are in particular known in vehicle steering.

Corresponding an advantageous embodiment of the invention is the Memory designed in the manner of a spring memory. Advantageously, can This ensures safe storage of the by the hydraulic pump pressurized hydraulic fluid. about the hardness of the spring of the memory can also the characteristic a decrease in pressure during removal of the useful volume be set.

In Further development of the invention is an actuation of the clutch introduced by a control device in the grinder. This allows an actuation of the clutch and thus the Possibility of a drive of the hydraulic pump via the grinder can be controlled from this central position.

Further, The measures improving the invention will be described below together with the description of a preferred embodiment of Invention shown in more detail with reference to FIG.

The single figure shows a schematic view of the device according to the invention for operating rope of a sailing ship, in which a winch 1 about a first grinder 2 by means of an intermediate, horizontal drive train 3 can be operated. Furthermore, a second grinder 4 over one between the first grinder 2 and the second grinder 4 provided, first clutch 5 with the drive train 3 be connected to a drive of the winch 1 to support. On the drivetrain 3 opposite side of the second grinder 4 is another, second clutch 6 placed over a toothed belt 7 the drive one parallel to the drive train 3 arranged hydraulic pump 8th to enable. The first clutch 5 and the second clutch 6 can in this case by means of a control device 9 in the area of the second grinder 4 be actuated, in which case preferably closing the one causes a simultaneous opening of the other. The hydraulic pump 8th filled with a drive by means of the toothed belt 7 over the second grinder 4 a spring store 10 with pressurized hydraulic fluid, which is used to drive one in the area of the drive train 3 and between the grinder 2 and 4 and the winch 1 placed hydraulic motor 11 is provided. This hydraulic engine 11 provides for pressurization for a corresponding rotational movement of the drive train 3 and thereby supports an operation thereof via the grinder 2 and 4 , However, this support effect by the hydraulic motor 11 only with one operation of the winch 1 and thus the drive train 3 to admit is between hydraulic engine 11 and memory 10 a servo unit 12 in the area of the drive train 3 placed on the drivetrain 3 applied torque via a torsion bar torque measurement, not shown here sensor-determined and in this case, depending on the moment flow of hydraulic fluid from the memory 10 to the hydraulic motor 11 allows, for example, by opening a corresponding valve.

By means of such a device, it is thus possible in maneuver-free sailing phases or in a single operation of the winch 1 over the first grinder 2 the spring store 10 over the second grinder 4 charge. The stored energy can be retrieved in the following maneuvers and thus provides appropriate support in the operation of the winch 1 , Accordingly, in particular maneuvers in which a high expenditure of force is necessary can be carried out at a lower load of the sailing crew.
