Definitions

  • This invention relates to the field of winch handles used on a variety of rotatable winches, particularly drum winches.
  • Rotary winches are well known and have been used for a variety of applications.
  • One such application, particularly for drum type winches, is the control of sail alignment on sailboats.
  • Such winches are used for raising and controlling the position of sails, as well as raising a crew ember to the top of the mast for maintenance and other onboard uses. They are available in manually operated or power driven forms.
  • An example of a manual single speed winch is disclosed in Reynolds, U.S. Patent No. 4,291,864.
  • Conventional winch handles are simple, manually rotated "crankhandles”. They have a stem that fits into a complementary recess on top of a manually rotated winch.
  • Hand held, portable powered devices have been developed for a broad spectrum of other applications, particularly as surgical/ dental instruments, assembly line tools and hand held power tools including rechargeable power sources for craftsmen. Their structures and capabilities have been designed to serve applications such as the above based on the specific requirements presented.
  • the powered winch handle of the present invention is useful for operating rotary winches, particularly drum winches. Such winches are standard equipment on both cruising and racing sailboats in the small and medium size ranges where the use of manually operated, rather than remotely electrically controlled, winches has been customary.
  • the powered winch handle is intended for both cruising and racing sailboats in the range of up to about 25 to 50 feet and is particularly advantageous for facilitating singlehanded sailing and sailing, particularly cruising, for those who otherwise find disabilities or the physical strength requirements of winch handling a limiting factor.
  • the winch handle disclosed is driven by a compact DC electric motor within the handle and fits with the winch through at least one drive stem.
  • the DC power source for this drive motor can be, for example, a removable, battery recharging pack or a shipboard DC power source to which the powered winch handle is connected by a waterproof electrical line.
  • the electric motor drives rotation of the drive stem through a transmission assembly, such as a gear train, that reduces the rate of rotation from that of the electric motor specifically to the range of about 10 to 130 rpms, the rate at which these rotary winches are usually rotated by manual labor.
  • the transmission assembly can be, for example, a series of individual reduction gears or a wormgear arrangement.
  • the drive assembly preferably includes articulating conical gear(s) that redirect the angle of rotation from that output by the DC motor, the long axis of the winch handle, to that of the drive stem. This angle can be fixed or adjustable and can range from 0 to 90 degrees of angle. Counterrotation of the winch handle is prevented by stationary resistance of the operator holding the powered winch handle. Thus, this also specifically limits the torque applied to the winch to the same general range as would have been applied by operation of a conventional "crankhandle", i.e. 10 to 60 foot pounds.
  • Fig. 1 is an elevational view of the environment of use of one embodiment of the powered winch handle of the invention, showing drum winches for reefing the jib sail .
  • Fig.2 is an elevational view of one embodiment of the powered winch handle of the invention in use.
  • Fig. 3 is a side cross-sectional view taken along line 3-3 of Fig. 2.
  • Fig. 4 is a top cross-sectional view taken along line 4-4 of Fig. 3.
  • Fig. 5 is an elevational view of another embodiment of the powered winch handle of the invention.
  • Fig. 6 is a side cross-sectional view taken along line 6-6 of Fig. 5 and also showing a detachable head for mounting on the universally configured drive stem.
  • Fig. 7 is a top cross-sectional view taken along line 7-7 of Fig. 5.
  • Fig. 8 is an enlarged partial view of another configuration of the drive head(s) of the present invention.
  • the invention provides a hand held, powered winch handle for rotation of a rotary winch.
  • the powered winch handle comprises a waterproof housing; a DC motor within and at one end of the housing and connectable to a DC power source therethrough; a winch drive head at the opposite end of the housing with at least one drive stem extending therefrom for engaging a rotary winch to provide rotation at a rate of about 10 to 130 rpms at a torque in the range of about 10 to 60 foot pounds; a transmission assembly interconnecting the drive motor and the drive head; and trigger means for controllably actuating rotation of the drive head.
  • the stem is provided with a number of features. It can, unlike the stem on conventional winch crankhandles, extend from both sides of the winch head, thus rotating clockwise on one side and counterclockwise on the other side.
  • the first and second drive stems extend in substantially opposite directions on an axis that is usually perpendicular, but optionally variable, with respect to that of the drive assembly.
  • the drive stems extend on an axis that is fixed substantially perpendicular to the transmission assembly.
  • the handle can have a single stem whose gear engagement can rotate in either direction based on the direction of rotational input to the transmission assembly or drive head.
  • the winch handle further comprises means for alternating the polarity of the DC motor to effect clockwise or counterclockwise drive stem rotation.
  • This feature is particularly contemplated for the purpose of meeting the need of two-speed manual winches.
  • These alternatives accomodate multi-speed winches that are used on relatively larger mid-range sailboats, where different mechanical advantages are provided by the winch depending on the direction in which it is rotated.
  • the drive stem can be so- configured as to allow for adjusting the relative angle of the winch drive handle to the winch.
  • the winch drive stem(s) comprise means for releasably coupling with fittings configured to engage with a variety of winches.
  • the winch handle is provided with snap-on fittings to accomodate ttje different shapes of handle recesses used by different winch manufacturers.
  • the powered winch handle is activated by a trigger mechanism that is connected by electrical contact switches with the DC drive motor.
  • the trigger means comprises at least one pressure sensitive element in contact with a portion of the interior surface of the waterproof housing. The trigger actuates only when manually depressed.
  • trigger plates or pads are positioned on opposite sides of the handle. Squeezing the handle at these positions actuates it and release of either or both turns it “off”.
  • the winch handle further comprises means for effecting variable drive head rotation rates responsive to variations in pressure on the trigger(s).
  • Fig. 1 shows a principal application for the powered winch handle of the invention, the singlehanded sailor on a small or medium size sailboat provided with drum winches W for control of jib sheets S that are used to adjust positioning of the jib sail.
  • Fig. 2 shows one embodiment of the powered winch handle of the invention, generally designated 1, engaged with manual winch W that it rotates to reel in or pay out jib sheet S.
  • Powered winch handle 1 is connected through a waterproof access in housing 2 to a waterproof outlet for an onboard power source by resiliently coiled waterproof electrical cable 3.
  • Housing 2 can be of varying diameter along its longitudinal axis. Housing 2 can be formed of any known flexible waterproof materials, such as silicone or neoprene. Part or all of its exterior surface can be textured, stippled, grained, or otherwise adapted to provide a more secure grip for the user. As shown, the user holds powered winch handle 1 stationary while actuating handle 1 to rotate the drum of winch W.
  • Figs. 3 and 4 are cross-sectional views showing the interior of this embodiment in more detail.
  • Housing 2 provides a waterproof access for waterproof electrical cable 4 leading to an external DC power source. It encloses DC drive motor 6 within a rigid csing casing 7.
  • Casing 7 can be made of suitable metals such as aluminum, brass and corrosion resistant alloys thereof.
  • Output shaft 8 of motor 6 delivers power to transmission assembly 10.
  • Transmission assembly 10 in turn, causes winch drive assembly 12 to rotate within a predefined range of revolutions per minute (RPMs) and a predefined range of torque.
  • Winch drive assembly 12 is adapted, in a variety of ways, to mate with a complementary recess in the winch to be rotated.
  • a portion of interior surface 14 of housing 2 is not supported by casing 7. Rather, opening 16 in casing 7 permits trigger plate 18 to be flush with or slightly raised against interior surface 14.
  • Trigger plate 18 is electrically connected through switch 19 to drive motor 6, which is engaged by depressing trigger 18.
  • Drive motor 6 is a conventional DC electrical motor with a centrally positioned rotating output shaft.
  • a conventional, commercially available DC motor within the range of about One-quarter to one horsepower is suitable for use. These generate output rpms in the range of about 500 to 2,000.
  • Conical gear 9 is mounted on or integral with the distal end of motor output shaft 8.
  • Transmission assembly 10 receives the power output of drive motor 6 through conical gear 9 which perpendicularly engages with first reduction gear 20.
  • the decrease in rpms and concomitant increase in torque develops through the sequence of beveled gears, illustrared by beveled gears 20 and 22, fitted on gear arbors 24 and 26, respectively.
  • Gear 22 is the output gear for transmission assembly 10.
  • Gear arbors 24 and 26 are seated or journalled into friction bearings 28a and 28b and 30a and 30b, respectively, for rotation on an axis perpendicular to the longitudinal axis of housing 2.
  • Friction bearings 28a, 28b, 30a and 30b are recessed into rigid csaing 7.
  • Transmission assembly 10 transmits the rotational force to winch drive assembly 12.
  • Winch drive assembly 12 receives the power output of transmission assembly 10 from output gear 22 which engages drive assembly gear 32.
  • Drive assembly gear 32 is mounted on drive arbor 34, an integral shaft formed of opposed arms 36a and 36b.
  • the ends of opposed arms 36a and 36b form drive heads 38a and 38b, respectively. Therefore, drive heads 38a and 38b rotate in opposite, that is clockwise and counterclockwise, directions.
  • powered winch handle 1 delivers rotary force to a winch, specifically at a rotation rate in the range of about 10 to 130 rpms at a torque in the range of about 10 to 60 foot pounds
  • Fig. 5 shows another embodiment of powered winch handle 1 that is provided with rechargeable battery pack 40 that attaches by waterproof electrical receptacles through housing 41.
  • Battery pack 40 is charged from an onshore or other conventional power source and supplies an extended period of power supply to powered winch handle 1 when they are electrically connected. Also shown is external selector 42 that permits the user to reverse the rotation of single drive head 44. Rotation is effected by squeezing trigger 46.
  • Figs. 6 and 7 are cross-sectional views showing the interior of this embodiment in more detail.
  • Trigger 46 is flush with or slightly raised against the interior surface of grip portion 48 and electrically connected through switch 50 to reversible gear or drive motor 52, such as a reversible permanent magnet DC gear motor.
  • Switch 50 is a conventional break-before-make double pole, double throw switch that reverses the polarity of motor 52, based upon the position selected with selector 42.
  • Worm wheel 56 is mounted on or integral with the distal end of motor output shaft 54 and drives worm 58.
  • Worm 58 is mounted on or integral with gear arbor 60. Also mounted on or integral with gear arbor 60 is beveled gear 62.
  • Gear arbor 60 is seated or journalled into friction bearings 64a and 64b for rotation on an axis perpendicular to the longitudinal axis of powered winch handle 1.
  • Beveled gear 66 is mounted on or integral with gear arbor 68 which is seated or journalled into friction bearings 70a and 70b.
  • Drive assembly gear 72 is mounted on drive arbor 74, an integral shaft formed of opposed arms 76a and 76b.
  • Arm 76a is seated or journalled into friction bearing 78, whereas arm 76b extends through a waterproof opening in the wall of housing 41 to end in universal drive stem 80.
  • Universal drive stem 80 removably engages a variety of winch fitting adapters 82 that removably attach to universal stem 80 and are each adapted for use with winch fittings of distinct complementary shapes.
  • Fig. 8 shows another configuration of the drive head(s) of the present invention where drive stem 84 has curved upper surfaces 86 and curved lower surfaces 88 that permit adjustment of the relative angle of winch handle 1 to the winch to be rotated for the ease and accessibility of the user while maintaining a secure articulation of drive stem 84 with the winch handle recess in a winch.
