Definitions
- the invention relates to an actuating device for a manually operable winch for operating a line, wherein a first end of an actuating lever is configured for cooperation with the winch, and wherein the actuating lever is substantially elongated.
- winches - also referred to as winches - are used to apply tractive forces to a line.
- winches are used for the operation of linen, such as pods, traps, other ropes of running goods or other rope ropes.
- linen such as pods, traps, other ropes of running goods or other rope ropes.
- winches There are a number of different types of winches, such as catchy, two-speed or multi-speed winches that have more or less complex winch gear.
- a winch can be motorized or manually operated.
- a particularly frequently used winch type is the catchy hand-operated winch for sailing ships.
- the rope to be operated is usually laid with a few turns around a winch drum and the winch drum is turned with a winch crank.
- the rope running onto the winch drum is pulled by the winch.
- An operator of the winch must also at least with one hand while pulling the rope running off the winch drum train. in order to maintain a required friction between the winch drum and the rope.
- Such a winch has a winch handle with a handle, with which the winch drum can be rotated by the operator in one direction (the rope is then pulled), while with a rotation of the winch handle in the other direction, a freewheel the winch handle is or can be, where the winch drum does not move. In freewheeling is prevented by pawls that the winch drum rotates against the pulling direction of the rope. In addition, holding the rope with one hand prevents the rope from slipping back over the winch drum, thereby loosening it unintentionally.
- a common winch In addition to a simple gear that has a sprocket on the winch drum with one or two pawls, a common winch often also has a gearbox that increases the torque introduced by the winch on the winch drum, for example, by one or more gears. This corresponds to a gearbox with a reduction gear.
- a gear with pawls or a gear with pawls and a reduction gear is referred to as catchy.
- a disadvantage of this prior art is that the rope to be pulled is constantly occupied in a clamping device of the self-hauling winch.
- a weaving of the rope ie a yielding of rope against the direction of pull of the winch, requires first the removal of the winch crank from the winch, the bringing of the winch crank to its storage location and then the release of the rope from the clamping device, which is comparatively complicated due to the design of such clamping devices.
- After loosening the running rope part in turn must be held by at least one hand of the operator. If the rope is to be pulled again, either only one hand is available or the rope must first be reinserted into the clamping device.
- the winch crank must be plugged back into the winch.
- the requirement is a rope constantly tighten or fire - for example, during a regatta or other wind-optimized sailing - the serving winch is relatively time consuming
- an object of the invention to provide a hand-operated winch and an actuator for the winch, which is particularly easy and quick to use.
- the object is achieved by an actuating device for a manually operable winch for operating a line, wherein a first end of an actuating lever is configured for cooperation with the winch, and wherein the actuating lever is substantially elongated.
- the actuating device according to the invention is characterized in that a line deflecting element is attached to the actuating lever at a predeterminable distance from the first end of the actuating lever, and that the actuating lever is connected to a return device, with which a predeterminable force in a predeterminable direction is exerted on the actuating lever.
- the basic idea of the invention is that the running rope can be held by the operator with one or both hands and at the same time it is possible to pull the operating lever and thus to operate the winch, so to pull the leash.
- the line deflection element functionally replaces, as it were, the handle of the otherwise usual hand crank on the winch. Accordingly, the winch is operated with the leash running and no longer as usual by hand.
- the running line is simply pulled by the operator and the tensile forces are guided by the Leinenumlenkelement in the lever.
- the rope to be pulled is placed on the running side of the winch around the Leinenumlenkelement, so that when pulling on the leash on the one hand ensures that the line does not unintentionally yield against its direction of pull, and on the other hand - at a correspondingly high tensile force of the operator - at the same time the operating lever is pulled, and so the winch drum rotates as desired.
- the reset device now ensures that the operating lever is moved back to a starting position when the operator reduces the pulling force on the rope. This is done by the operator so that the tensile force on the rope is not reduced so much that the rope does not yield unintentionally, but the operating lever is moved back in the freewheel of the winch back to its original position.
- a winch is thus particularly easy to use, since the operator has both hands free for the leash.
- the winch is operable, namely by the operator holding, pulling or pulling the line.
- the drawing is namely according to the invention also with the leash, as described above be.
- the leash is also faster to operate in this way.
- the hitherto necessary holding the leash with one hand and simultaneous fetching, plugging into the winch and then turning the winch handle with the other hand is completely eliminated.
- the time-consuming release from the clamping device of the self-hauling winch is also eliminated. Since only one hand is needed to operate the actuator, the operator has his other hand free, for example, to control the vessel.
- the first end of the actuating lever is designed such that it has a crank pin designed as a star base.
- the star base often has an octagonal design.
- Other connection methods are also conceivable here, for example the flanging of the actuating lever on a winch threshold or the insertion of the end into a plug-in device on the winch sill.

- the actuating gear for example, have pawls, which allows the rotation of an actuating gear shaft - for example, the mounting plate - only in one direction, while in the other direction of rotation is a freewheel. This essentially corresponds already to the functions of the catchy winch.
- the actuating gear can also have a reduction ratio.
- actuating gears are possible for this purpose, for example actuating gears with pawls and toothed ring, actuating gear with pawls, toothed wheels and toothed ring, or actuating gear planetary gear.

It has been found that a maximum pivot angle between 45 ° and 150 ° are particularly advantageous. However, it is also conceivable without further maximum swivel angle of 30 ° to 180 °. Although maximum pivoting angles of over 180 ° are mechanically conceivable without further problems, however, problems then arise in pulling the line during operation of an actuating device together with a winch.
- the return device for the second actuating lever 74 a coil spring 90, the shape of which is formed from a spirally rolled up ribbon-like spring steel.
- the radially inner end of the coil spring 90 is fastened in a groove 92 on the second actuating lever 74.
- the radially outer end of the coil spring 90 is suspended around a retaining pin 94 which is fixedly connected to the mounting plate 62.
- the spring transmits the spring forces to a fixedly mounted component, while the spring forces also act on the second actuating lever 74. Otherwise act no forces on the operating lever, the coil spring 90 causes the second operating lever 74 remains in its first operating position 76 or is moved there.
