Definitions

  • the present invention generally relates to exercise equipment, and more particularly to rowing machines utilizing gear changing mechanisms.
  • Rowing machines are stationary exercise devices that simulate the motion and forces during rowing.
  • Rowing machines generally include a frame having a movable seat and foot rests and a handle that is connected to a resistance unit. During the drive portion of the stroke, the handle pulls on the resistance unit, which provides resistance to the motion of the handle. During the recovery portion of the stoke, there is no resistance to the motion of the handles.
  • the handle is connected to the resistance unit through a chain or cord attached to the handle and a mechanism to take up slack of the chain or cord during the stroke.
  • Resistance units for such rowing machines may include one or more of a flywheel, an air or water resistance mechanism, or a magnetic resistance mechanism which provide a resistance force to the pulling of the handle that increases with the speed of the handle.
  • Magnetic resistance mechanisms are electronically controllable, and when used in combination a flywheels and/or an air or water resistance mechanism, can vary the resistance force to the pulling of the handle over a wide range.
  • rowing machines do not provide an easy way for the rower to adjust the resistance during practice.
  • the rowing machine may adjust the resistance through a magnetic resistance mechanism, the rower must work against this resistance and cannot, as in bicycles, for example, shift the resistance mechanism to obtain a larger or smaller resistance during rowing.
  • an rowing machine that provides the rower with a greater degree of resistance control during rowing.
  • Such a rowing machine should be easy for the rower to operate and should be comprised of standard exercise equipment mechanisms.
  • the present invention overcomes some of the disadvantages of prior art by providing a rowing machine connected to a resistance unit by a chain and gear cassette/derailleur configuration in which the chain extends from a handle, through the derailleur, and though the gears.
  • This configuration provides for a smooth operation not found in other systems.
  • a rowing machine comprising: a resistance unit including a gear cassette comprising a plurality of gears coupled to a mechanism to resist the rotation of the gear cassette; a frame adapted for placing on the ground and attached to the resistance unit; a seat movable along the frame; a handle; a chain having a first end attached to the handle and a second end attached to the frame; a derailleur attached to the frame; and a gear shifter operably connected to the derailleur.
  • the chain extends, sequentially, from the handle, through the derailleur, and engages a gear of the plurality of gears, such that the engaged gear is selectable using the gear shifter.
  • the rowing machine attachment connectable to a resistance unit, where the resistance unit includes an axle and a gear cassette comprising a plurality of gears coupled to a mechanism to resist the rotation of the gear cassette.
  • the rowing machine attachment includes: a frame adapted for placing on the ground and including a fork end adapted to accept the axle of the resistance unit; a seat movable along the frame; a handle; a chain having a first end attached to the handle and a second end attached to the frame; a derailleur attached to the frame; and a gear shifter operably connected to the derailleur.
  • FIGURES 1 and 2 are side and top views, respectively, of a first embodiment rowing machine 200, with a rower R in at the end of a stroke
  • FIGURE 3 is a top view of a handle 237 and chain 233
  • FIGURE 4 is a side view illustrating the chain and a resistance unit 250
  • FIGURE 5 is an exploded view 5-5 of showing one embodiment of a chain return mechanism 232.
  • rowing machine 200 includes a frame 210, a resistance unit 250, and power transmission components 230 connecting the frame and resistance unit.
  • Frame 210 includes a first portion 211, a second portion 219 and a third portion 221.
  • First portion 211 is generally horizontal.
  • Second portion 219 is attached to first portion 211 and includes a first end 223 that extends to the ground and a second, forked end 225 attached to an axle 253 of resistance unit 250 and includes legs 213 for supporting the rowing attachment on the ground and a foot support 215 including foot straps 216.
  • Third portion 221 is attached to and extends above second portion 219.
  • Resistance unit 250 includes a freewheel or freehub assembly including a cassette of gears 251 connected to axle 253 through a one-way clutch that engages with a resistance mechanism (both of which are not shown) within the resistance unit.
  • Resistance unit 250 may, for example and without limitation, be generally similar to prior art resistance units of a wheel off bicycle trainer, such as the Tacx NEO (Garmin Ltd, Schaffhausen, Switzerland). Such resistance units provide a force to resist the rotation of the cassette of gears 251 in one direction and provides little force to resist the rotation of the cassette of gears in the opposite direction.
  • Resistance unit 250 may include one or more of a flywheel, an air or water resistance mechanism, or a magnetic resistance mechanism that is electronically controllable.
  • Resistance unit 250 also includes sensors to measure the power and cadence of the cassette of gears 251, and electronics to accept the sensor measurements, control the resistance to the cassette of gears, and provide information for display on a screen 255.
  • Power transmission components 230 include chain 233 coupled to the handle 237 with an attachment ring 301, a first chain guide 241 attached to third frame portion 221, a derailleur 243 attached to second end 225 in a position that is above cassette of gears 251 (as shown in FIG. 4 ), a second chain guide 245 attached to second portion 219, and a chain return mechanism 232.
  • Power transmission components 230 also include a gear shifter 247 attached to the handle 237 and a cable 249 connecting the gear shifter and derailleur 243, and a seat 217 including rollers to allow the seat to move along first frame portion 210.
  • first portion 211 is angled relative to the horizontal to aid the return of rower and at the end of the stroke.
  • derailleur 243 may be an electronic system, such as a Shimano Di2 electric drivetrain (Shimano Inc, Sakai, Japan) or Campagnolo EPS (Campagnolo Vicenza, Italy), or a wireless system, such as SRAM eTap (SRAM, Chicago, IL).
  • Shimano Di2 electric drivetrain Shimano Inc, Sakai, Japan
  • Campagnolo EPS Campagnolo Vicenza, Italy
  • SRAM eTap SRAM, Chicago, IL
  • Chain return mechanism 232 is generally contained within second portion 219 and includes an elastic cord 235 coupled to an end of chain 233, rollers 501, 503, 505, and 507 supported on second frame portion 219 by bolts 511 and nuts 513.
  • An end 239 of elastic cord 235 is attached to first end 223.
  • the handle 237 also includes a mount 303 for a mobile device (not shown).
  • the combination of chain 233 and elastic cord 235 referred to herein as a compound cable 231, extends from the handle 237 to first end 223, with chain 233 being guided over first chain guide 241, through derailleur 243, over gears 251, and guided over second chain guide 245.
  • Elastic cord 235 extend from chain 233 around rollers 501, 503, 505, and 507 and is attached to frame 210 at first end 223.
  • chain return mechanism is a spring loaded cylinder that takes up the slack in chain 233, or a gravity return mechanism (see, for example, US Patent Application Publication No. US20140243163A1 , the content of which are incorporated by reference).
  • Resistance unit 250 thus provides a force that counters forces provided by a rower.
  • the force provided by resistance unit 250 is transferred from axle 253, to one of gears of gear cassette 251, to chain 233 of compound cable 231, to the handle 237.
  • the gear shifter 247 and deraille 243 allow for rower to control the resistance. Slack in chain 233 is taken up by chain return mechanism 232.
  • a rowing machine attachment 260 is provided that is connectable to a resistance unit, such as resistance unit 250.
  • the rowing machine attachment includes the following components of rowing machine 200 described above: frame 200 adapted for placing on the ground and including a fork end adapted to accept the axle of the resistance unit; seat 217 movable along the frame; a handle 237; chain 233 having a first end attached to the handle and a second end attached to the frame; derailleur 243 attached to the frame; and gear shifter 247 operably connected to the derailleur.
  • frame is attached to the axle of the resistance unit, as illustrated in FIG. 1 , and where the chain extends, sequentially, from the handle, through the derailleur, and engages a gear of the plurality of gears, such that the engaged gear is selectable using the gear shifter.
  • FIG. 1 is a side view of the first embodiment rowing machine attached to the bicycle trainer resistance unit, with the rower at the beginning of a stroke.
  • a tension is provided to chain 233 by resistance unit 250 and while elastic cord 235 takes up any slack in compound cable 231.
  • the tension in chain 233 is provided by the force required to rotate gears 251, which may be regulated by the rower using gear shifter 247 to activate derailleur 243 and thus select a gear of gears 251.
  • the force required to rotate gears 251 may be adjusted using software in resistance unit 250.
  • certain embodiments of resistance unit 250 include sensors to monitor the rotation speed of gears 251 and electronics to determine power expended during rowing.
  • resistance unit 250 is in communication with a computer or electronic device, such as a smartphone, which can receive information from resistance unit 250 and which may also provide instructions to the resistance unit to modify the resistance provided by the resistance unit.
  • a computer or electronic device such as a smartphone
  • the end of stroke is illustrated in FIG. 1 .
  • rower R moves forward to the position shown in FIG 6 .
  • the one-way clutch permits the chain to move without resistance through resistance unit 250 and return mechanism 232 takes up slack in compound chain 231.
  • a rowing machine having a derailleur below the gears provides engagement of the one way-clutch at the beginning of a stroke that is not smooth.
  • shifting under load as on an upstroke
  • placing the derailleur above the gears, as in FIG. 4 forces the gear shift to happen on a down stroke, when system is not under load and helps to dampen one way-clutch engagement at the beginning of a stroke, resulting in a smoother and more natural motion.
