- the provided foot plate system 22 may be replaced or interchanged with the foot plate systems used in rowing boats. This allows rowers to use exactly the same foot positioning they use in a boat. This ability to use the same foot positioning as achieved in a boat is achievable because carriage 2 is provided with a sufficient width between rails 11 , so that the conventional row boat foot plate systems can be used.
- This feature is important because it allows for correct biodynamic positioning of the feet due to the foot plate system being identical to, or near identical to a rowing boat, which is an advantage over the prior art foot rests which straddle beams or are not set up correctly due to other positioning constraints.

- the positions A and B are also indicated for the handle carriage 3 , handle 19 and feet 31 .
- This relative movement between the seat, carriage and base together with the advantageous positioning of the rower's feet, provides a simulation set-up which is dynamically desirable to mimic row boat rowing.
- a rower could transfer directly to machine 1 their foot plate system from the rowing boat. This is important, particularly at the elite level, where footplate systems have become more sophisticated and specifically tailored to compensate for the rower's heel flexibility and optimum power output. It makes sense to be able to replicate the rower's set up in the boat, on a rowing simulation machine relied upon for a significant proportion of alternate training load, if this customised set up is used to maximise performance and also avoid injury from repetitive movement exercise.
- the spacing of rails 11 of carriage 3 allows the mounting of the conventional and modern/customised footplate systems available on the market today.
- the feet position can be varied to match different boat types where the feet spacings are of different widths.
- the rowing simulation machine 1 of the present invention can also be connected in end-to-end relationship or side-by-side relationship to mimic real on water crew rowing. This is achieved by using simple rod connectors to join the carriages of the machines.
- Another advantage of this embodiment of the present invention is that not only does it achieve “dynamic simulated rowing”, it also uses less floor space than the “Concept 2 Slide” sliding track system by Concept 2, Inc. This is because the overall length of the machine of the present embodiment can be constructed so that it is about 300 mm shorter than the Concept 2 Slide arrangement when stationary, and about 400 mm shorter comparing the extent of the machines when used dynamically.
- the reduced overall length of the present embodiment by eliminating the need to provide a pair of slides for each machine, improves greatly the floorspace required to connect two or more machines. This allows the possible connection of more machines in the space available. As most gyms and rowing clubs are limited in the space available for the crew simulation option, a reduced overall length and simplified connection method increases the opportunity for this crew simulation option.
- Another advantage of the present embodiment of machine 1 when compared to the “Concept 2 Slide” prior art, is that as a result of the shape and configuration of base 2 on legs 10 , it is relatively easy to maintain the hygiene of the floorspace below machine 1 , after active use of the machine. This is particularly important in public gyms and rowing clubs.
- carriage 3 should preferably be lockable to base 2 , so that the machine can be used in similar fashion to a stationary rowing machine to perform specific exercises or for coaching purposes.
- each of said rails of said second set of rails is curved or inclined at least one end thereof. This could be used instead of elastic cord centering, to prevent the seated rower from hitting the end stops of carriage 3 during use.

Description
- The present invention relates to rowing simulation machines and in particular to dynamic rowing machines.
- Rowing machines are well-known for the purposes of building up general fitness and/or for training specifically for rowing and related sports. Rowing machines allow the user to exercise both upper body and lower body strength by simulating roughly the movement required to propel a row boat through the water.
- There is a variety of prior art rowing machines, including stationary rowing machines used in gymnasiums, rowing clubs and the like. In many instances these stationary rowing machines are used as ergometers. One such prior art stationary rowing machine is shown in U.S. Pat. No. 4,396,188 (Dreissigacker et al). This machine has a monorail beam upon which a seat with rollers is able to slidably move therealong. A second beam (or arm) supporting a flywheel/fan mechanism is connected at the fore end of the monorail beam. The beam has footrests on either side thereof. A rowing handle is connected to the flywheel/fan mechanism via a drive cable. The flywheel/fan mechanism acts as an “energy dissipating system” and is stationary relative to the frame. A rower (user) seated in the movable seat and with feet secured to the footrests, is able to exercise by holding the rowing handle. Typically the user will start in a “catch position”, then drives backwards by extending his legs and swinging his torso through the vertical position, and finishes the stroke by drawing the handle into his abdomen. The user then uses his legs to draw his body back to the catch position.
- There are also variations on similar machines where drag mechanisms acting on air or water provide resistance to the rower.
- There are also known rowing machines that simulate or attempt to simulate the movement of oars such as U.S. Pat. No. 4,743,011 (Coffey), U.S. Pat. No. 5,092,581 (Koz) and Publication No. WO2005/025685 (Roach). Most of these machines have oars or other components simulating the movement of oars, and generally require more space than the machines of the type shown in U.S. Pat. No. 4,396,188. These rowing machines that simulate oars are generally more complex and costly than stationary rowing machines, and occupy more space when in use.
- As such, there has been a preference in many rowing clubs to use the stationary rowing machines similar to those shown in U.S. Pat. No. 4,396,188, particularly where cost and space are of importance. However, these known stationary rowing machines are acknowledged by health professionals as being potentially detrimental to the rower, by increasing the likelihood of injury to the rower's knee, back and shoulders due to the increased loading on the body. Another disadvantage is that they cause rowers to develop improper coordination patterns.
- A number of attempts have been made to provide a dynamically balanced rowing machine, which more closely simulates the power distribution characteristics of rowed boats, to overcome the disadvantages and health risks associated with stationary rowing machines.
- U.S. Pat. No. 5,382,210 (Rekers) describes a dynamically balanced rowing simulator with an independently moving energy dissipating system and seat mounted on a substantially horizontal monorail beam frame. At least one end of the monorail is curved to prohibit the moving energy dissipating system and seated rower from hitting the end stops of the monorail beam frame during use, and to operate in the centre of the monorail beam length.
- Another attempt to provide a dynamic rowing simulator, is to mount a stationary rowing machine of the type described in U.S. Pat. No. 4,396,188 on a sliding track system as is offered by Concept 2, Inc as a “
Concept 2 Slide”. The sliding track system comprises two slides. Each slide comprises a base with two tracks and a carriage with wheels that runs on the tracks. Light shock cord tension keeps the carriage centered on the base. It takes two slides aligned aft to fore to “float” or “dynamically support” a prior art stationary rowing machine. By mounting the complete stationary rowing machine on a fore and aft sliding track system the rowing machine converts to a dynamic rowing machine whereby the seat and the energy dissipating system can now move independently of each other. - The disadvantage of the prior art stationary machine being mounted on sliding tracks to convert to a dynamic rowing simulator, is that the substantial length of floorspace area it uses and the risk to the rower getting on and off the machine, and to others in close proximity of the moving tracks at floor level. Also the sliding tracks are large accessories that have to be stored separately when not in use. The sliding tracks also make it difficult/practical to maintain the hygiene of the floorspace below the machine after active use of the machine, particularly important in public gyms and rowing clubs.
- The “Concept 2 Slide” system is also designed to also allow two or more machines to be connected end to end to simulate a crew boat. The space required to connect these machines in a room is significant.
- Whilst these prior art dynamic simulators provide a realistic motion and the benefits are widely publicised, the foot plate where the rower attaches his feet are mounted either side of a monorail beam or energy dissipating unit, and increase the width position of the feet further apart than would be found in a conventional rowing boat. This is a disadvantage, as to correctly simulate the biodynamics of the rower's leg drive during the rowing stroke it is preferable that the rower's feet be positioned closer together, than can be achieved with his feet on either side of a monorail beam, as is the case with the
Concept 2 machines. - Because the power distribution character of a dynamic rowing machine is closest to the power distribution profile of what is produced in a rowing boat, it is then important that the use of rowing machines for training to be utilised and maximised to achieve the optimum performance from the rower. Studies have found that the foot position of the rower can affect the efficiency, effectiveness and maximum power output of the rowers. Therefore the ability to use on a dynamic rowing machine the same efficient foot plate system as used on row boats, would ameliorate rowing simulation machines and the training of rowers using them.

rail 8 of the first pair of rails onbase 2 is longer than the length of eachrail 11 of the second pair of rails oncarriage 3. The length of eachrail 8 of the first pair of rails is preferably about 500 mm longer than the length of eachrail 11 of the second pair. -
Energy dissipating unit 5 is fixed tocarriage 3.Energy dissipating unit 5 comprises aframe 16 for supporting aflywheel 17 mounted on a rotatable shaft 18. In thisembodiment flywheel 17 is a conventional flywheel that provides resistance by air, however in another not shown embodiments could provide resistance by water or magnetic means. - A
handle 19 is connected to a drive means 20 for converting a translation ofhandle 19 into a rotation offlywheel 17. In this embodiment drive means 20 is a bicycle type chain, however in other not shown embodiment cable, belt or rope may be substituted for the chain. -
Chain 20 passes through a take up means that allowschain 20 long enough to permit a normal stroke of about 1.6 meters to be housed in a relatively small compartment. The detail of the take up means is not provided here, as it can be of a known type using elastic cord and pulleys, such as that described with reference to FIG. 2 of U.S. Pat. No. 5,382,210. -
Flywheel 17 may have an adjustable resistive load. Details of how the resistive load flywheel can be adjusted by conventional means known in the prior art, including U.S. Pat. No. 5,383,210. -
Energy dissipation unit 5 also includes aconventional monitoring unit 13, including a display panel, tachometer and the like for monitoring training and for ergometer use. - A foot rest assembly 21 is disposed within
carriage 2 between the second set ofrails 11. The foot rest assembly 21 may preferably comprise mounts to receive a foot plate system 22, which is provided with themachine 1. - However, the provided foot plate system 22 may be replaced or interchanged with the foot plate systems used in rowing boats. This allows rowers to use exactly the same foot positioning they use in a boat. This ability to use the same foot positioning as achieved in a boat is achievable because
carriage 2 is provided with a sufficient width betweenrails 11, so that the conventional row boat foot plate systems can be used. - This feature is important because it allows for correct biodynamic positioning of the feet due to the foot plate system being identical to, or near identical to a rowing boat, which is an advantage over the prior art foot rests which straddle beams or are not set up correctly due to other positioning constraints.
- In use a rower (user) 30 is seated in
seat 4, and places his feet in the foot plate system 22 mounted on assembly 21. The heels of the rower's feet are disposed between theside walls 26 ofrails 11, withcarriage 3 mimicking or simulating a row boat. This can be seen from the positioning ofheel portions 23 of foot plate system 22 inFIG. 2 , and by the location of thefeet 31 ofrower 30 shown inFIG. 8 . - The rower grasps
handle 19 and begins to row. Ascarriage 3 andseat 4 are relatively moveable to each other as well asbase 2, themachine 1 allowscarriage 2 to move backward and forward under the rower. This action is similar to the movement of a boat on the water. -
FIGS. 4 to 7 , show various positions of the carriage as it is moved relative to the base. -
FIG. 8 depicts an overlay view of a “rower 30” in two distinct positions, the first in a “catch position”, shown as A, and the second shown as B with legs extended similar to the end of stroke. The positions A and B are also indicated for thehandle carriage 3, handle 19 andfeet 31. - This relative movement between the seat, carriage and base together with the advantageous positioning of the rower's feet, provides a simulation set-up which is dynamically desirable to mimic row boat rowing. As previously mentioned, a rower could transfer directly to
machine 1 their foot plate system from the rowing boat. This is important, particularly at the elite level, where footplate systems have become more sophisticated and specifically tailored to compensate for the rower's heel flexibility and optimum power output. It makes sense to be able to replicate the rower's set up in the boat, on a rowing simulation machine relied upon for a significant proportion of alternate training load, if this customised set up is used to maximise performance and also avoid injury from repetitive movement exercise. - As previously indicated the spacing of
rails 11 ofcarriage 3 allows the mounting of the conventional and modern/customised footplate systems available on the market today. The feet position can be varied to match different boat types where the feet spacings are of different widths. - Because the power distribution character of a dynamic “rowing simulation machine” is closest to the power distribution profile of what is produced in a rowing boat, it is then important that the use of rowing machines for training be utilised and maximised to achieve the optimum performance from the rower. Studies have found that the foot position of the rower can affect the efficiency, effectiveness and power output of the rowers. Therefore the ability to use the same row boat foot plate system that has been developed for this reason on
rowing simulation machine 1 is advantageous. - It should be understood that the
rowing simulation machine 1 of the present invention can also be connected in end-to-end relationship or side-by-side relationship to mimic real on water crew rowing. This is achieved by using simple rod connectors to join the carriages of the machines. - Another advantage of this embodiment of the present invention is that not only does it achieve “dynamic simulated rowing”, it also uses less floor space than the “
Concept 2 Slide” sliding track system byConcept 2, Inc. This is because the overall length of the machine of the present embodiment can be constructed so that it is about 300 mm shorter than theConcept 2 Slide arrangement when stationary, and about 400 mm shorter comparing the extent of the machines when used dynamically. - The reduced overall length of the present embodiment, by eliminating the need to provide a pair of slides for each machine, improves greatly the floorspace required to connect two or more machines. This allows the possible connection of more machines in the space available. As most gyms and rowing clubs are limited in the space available for the crew simulation option, a reduced overall length and simplified connection method increases the opportunity for this crew simulation option.
- Another advantage of the present embodiment of
machine 1, when compared to the “Concept 2 Slide” prior art, is that as a result of the shape and configuration ofbase 2 onlegs 10, it is relatively easy to maintain the hygiene of the floorspace belowmachine 1, after active use of the machine. This is particularly important in public gyms and rowing clubs. - It should be noted that
carriage 3 should preferably be lockable tobase 2, so that the machine can be used in similar fashion to a stationary rowing machine to perform specific exercises or for coaching purposes. - In another not shown embodiment each of said rails of said second set of rails is curved or inclined at least one end thereof. This could be used instead of elastic cord centering, to prevent the seated rower from hitting the end stops of
carriage 3 during use. - The term “comprising” as used herein (and its grammatical variations) is used in the inclusive sense of “having” or “including” and not in the exclusive sense of “consisting only of”.
