Definitions

  • This invention relates to exercise machines, particularly exercise machines that improve a user's strength and flexibility.
  • the partner After the subject performs the initial maximum ROM stretch, the partner holds the relevant limb in the stretched position to provide resistance against movement while the subject performs contraction of the same muscle group. It is important that the subject and the training partner are in constant communication so that the training partner does not apply excessive resistance to the subject when contracting as this may easily result in overstretching and serious damage to the muscle fibres.
  • an exercise machine including: a base; a pair of foot supports; guide means to accommodate sliding of the pair of foot supports away from and toward each other; and body support means, adjustable relative to the guide means, to stabilise a user facing in one of a plurality of directions when using the exercise the machine; wherein a user places a foot on each of the pair of foot supports and slides the foot supports apart to assume a stretched position in which leg muscles are stretched, and exits the stretched position by contracting the leg muscles to slide the foot supports together.
  • the base is preferably placed on a floor or other supporting surface on which the exercise machine is to be used.
  • the base may be of any suitable shape or cross section and may consist of a plurality of base members or feet to facilitate distribution of the mass of the exercise machine over the supporting surface.
  • it may be desirable to have a base which distributes the mass of the exercise machine over a larger area to ensure that the machine remains stable when in use.
  • stability may be achieved by manufacturing the base from a particularly heavy material and/or anchoring the base to the supporting surface.
  • the foot supports may be foot platforms, pads or other suitable means for supporting the mass of the user. Accordingly, each foot support may house all or part of the foot as well as providing a support for the base of the foot.
  • Foot retaining means may be provided on each of the foot supports to ensure that the user's foot is securely retained on the foot support and does not slide when the user assumes or exits the stretched position.
  • the foot retaining means may be in the form of a band or strap, a foot cup, a textured surface on the foot support, or employ any other suitable means.
  • the foot supports have a rubberised surface to provide extra cushioning to the user and prevent foot slippage.
  • the foot supports may have a portion of gradually increasing thickness along the inside edge of each foot support providing a "lip" which prevents the user's foot from sliding off the foot support when assuming, holding, contracting or exiting the stretched position.
  • the guide means may be in the form of tracks, beams, rails or other suitable means which facilitate sliding of the foot supports toward and away from each other with little or no friction or resistance to sliding.
  • the guide means may be provided by a single track, beam or rail upon which the foot supports slide.
  • the guide means may have a central point away from which the foot supports slide when the user moves into the stretched position and toward which they slide when the user exits the stretched position.
  • each foot support may slide on separate guide means which are joined at a central point.
  • the guide means may be rectilinear to accommodate a straight angle between the user's left and right legs when in the stretched position.
  • each of the guide means is adjustable relative to the horizontal to accommodate inclined, straight or declined sliding of the foot supports.
  • the guide means When in a declined arrangement, the guide means form an inverted "V" wherein the user's legs form an acute or an obtuse angle. This assists the user in adopting the principles of Proprioceptive Neuromuscular Facilitation (PNF) when stretching.
  • PNF Proprioceptive Neuromuscular Facilitation
  • the guide means When in an inclined arrangement, the guide means form a "V” and the user's legs form a reflex angle or "hyper-stretch” when in the stretched position.
  • the exercise machine includes biasing means for returning the foot supports to a "home position" when the user is not sliding the foot supports apart.
  • Biasing means may be provided in any suitable form, such as by way of a spring arrangement or using a hydraulic, magnetic, counterweight or other suitable system.
  • the exercise machine further includes linking means to link movement of the two foot supports so that they remain equidistant from the home position during use either with or without biasing means. This may occur by way of a cable system, electronic or pneumatic drive or other suitable means to ensure that movement of the two foot supports along the guide means is balanced to bring about an even stretch. It is preferred that the linking means adds little or no resistance to the foot supports sliding along the guide means. However, in some modes of use it may be desirable to incorporate a level of resistance to sliding so that the relevant leg muscles can be trained in strength as well as flexibility.
  • the exercise machine may also include stopping means to preclude movement of at least one of the foot supports until a suitable force has been applied so that the foot supports do not slide out from under the user when the user mounts the exercise machine.
  • the stopping means may be configured to prevent biased foot supports from hitting each other when they automatically return to the home position.
  • the stopping means includes a detent and roller arrangement.
  • the exercise machine may also include end means to limit the distance over which one or both of the foot supports slide. Inclusion of end means at a suitable location along the guide means minimises the risk of muscle damage due to overstretching by ensuring that the foot supports do not slide apart further than the user's leg length and flexibility can accommodate.
  • end means is particularly suitable for ensuring safe use of the exercise machine by beginners who may not be flexible enough to assume a deep stretch.
  • the end means are removable and can be located at different positions along the length of the guide means to incrementally increase or decrease the effective distance over which the foot supports slide.
  • the exercise machine can accommodate shorter users and users with shorter legs.
  • the foot supports are adjustable to accommodate a range of foot orientations such as by tilting and/or swivelling. Accordingly, one or both of the foot supports may be parallel with the ground, inclined toward the base or inclined away from the base.
  • the foot supports may be adjusted to accommodate orientations in which the users feet are in line with the guide means, perpendicular to the guide means, or at any angle therebetween. This facilitates flexion or extension at the ankle, depending on the orientation or angle of the foot supports and provides for more comfortable stretching.
  • the orientation of each of the pair of foot supports is independently adjustable. This is particularly suitable when using the exercise machine to improve flexibility in the "front stretch" position since the front and back feet are likely to be oriented and/or flex in different directions.
  • the orientation of the foot supports may be self adjusting or controllably adjustable whilst the user assumes or exits the stretched position.
  • Adjustability of the body support means relative to the guide means facilitates stabilisation of the user when facing in one of a plurality of directions when using the exercise machine. These directions may include a first direction in which the user faces along the guide means, a second direction in which the user faces away from the guide means and any direction between the first and second directions. In the first direction, the user can comfortably perform a front stretch. In the second direction, the user can comfortably perform a side or adductor stretch.
  • the body support means may be adjusted by swivelling or rotating the body support means relative to the guide means and the base, and locking the relative position of these parts to prevent them from moving during use of the machine.
  • the body support means is adjustably attached to the base and includes a handle positioned either side of the user.
  • the handles are grasped by the user's hands.

  • an exercise machine 1 is shown with a base 2, a pair of foot supports 4a and 4b and guide means 6a and 6b along which the foot supports slide.
  • Adjustable body support means is provided in the form of handles 8a and 8b.
  • a user places a foot on each of the pair of foot supports 4a and 4b and slides the foot supports apart to assume a position in which the leg muscles are stretched.
  • the user contracts the leg muscles and slides the foot supports 4a, b together.
  • handles 8a, b are used to provide stability to the user.
  • Base 2 provides a firm footing for the exercise machine 1 and is provided by a steel plate which supports the combined mass of the machine and the user. Any suitable base shape and/or material may be used. Preferably, a heavy material such as steel is used to prevent accidental movement of the exercise machine. Alternatively or additionally, the base may be anchored to the floor or other supporting surface on which the exercise machine is used by bolts or other fastening means to ensure stability during use. Foot supports 4a,4b slide away from and toward each other along guide means 6a, 6b.
  • rollers (not shown) attached to the underside of the foot supports and which are configured to ride along tracks (not shown) formed in the top of the corresponding guide means.
  • one or more rollers may be attached to each of foot supports 4a,4b such as by way of a bracket or arm 5, with the one or more rollers configured to roll along tracks in the underside of the corresponding guide means.
  • sliding movement of the foot supports 4a,4b along guide means 6a, b is as close to "frictionless" as is possible.
  • the foot supports 4a,4b are preferably linked in such away that they remain equidistant from a starting point or "home position" during use of the machine. In the embodiment illustrated, this is achieved using a pulley and cable system such as the one shown in Figure 2.
  • Foot supports 4a, b are attached at fixed locations to a continuous cable 7 so that sliding foot support 4a away from the home position along guide means 6a causes the cable to move around the pulleys in such a way that foot support 4b also slides away from the home position, along guide means 6b by the same amount. This ensures that an evenly balanced stretch is experienced by the user.
  • foot supports 4a, b are biased using a spring (not shown) or other suitable means so that they retract automatically to the home position in the absence of a sliding force being applied by the user. The strength of the spring may be varied, depending on the desired force with which the foot supports retract to the home position.
  • a weaker spring may be used for machines designed to develop muscle strength as well as flexibility in which the user must use their leg muscles to supply most of the sliding force which slides the foot supports back to the home position when the machine is in use.
  • the spring bias may be suitable for retaining the foot supports at the home position when the machine is not in use (i.e. when the foot supports are not supporting the mass of the user). It is desirable that the biasing means or "self retraction" mechanism urges the foot supports to return to the home position regardless of the attitude or angular disposition of the guide means.
  • the foot supports must be retained on the surface of the guide means in such a way that they do not lift off or "de-rail" from the guide means when they retract to the home position. This may be achieved by retaining the foot supports in tracks along the guide means, or retaining rollers on which the foot supports slide in tracks along the guide means. Alternatively, rollers or bearings may be provided both above and below the guide means to ensure that the foot support does not leave the guide means. The foot supports may retract to the home position with a significant amount of force, depending on the strength of the spring.
  • a brake or other suitable stopping means is included to stop the foot supports when they reach the home position. It is also desirable that the stopping means prevents the foot supports from sliding out from under the user when the user first places their feet on the foot supports. Inclusion of a stopping means also minimises the possibility of injury to the user or another person as a result of the foot supports "slamming" together, jamming a finger, toe or other body part.
  • the stopping means may be provided in any suitable form.
  • the "stoping means” includes a detent and roller brake arrangement such as the one illustrated in Figure 3. Figure 3 shows a detent and roller arrangement in which a brake roller 37 is attached to one of the foot supports 4a using a brake arm 29.
  • brake roller 37 becomes seated in detent 38.
  • the detent is angled in such a way that the sliding force required to remove the brake roller from the detent can be readily supplied by the user whilst being sufficient to prevent accidental removal of the brake roller from the detent.
  • This brake is adjustable to accommodate various weights and forces applied by different users, or during different exercises.
  • linking means links the movement of the two foot supports, a single stopping means can prevent both of the foot supports from moving.
  • a stopping means such as the detent and roller arrangement of Figure 3 could be provided for each of the foot supports and may be particularly useful in an embodiment in which movement of the pair of foot supports is not linked.
  • the exercise machine of Figures 1A to 1 D also show pairs of holes 15 along the length of guide means 6b. These holes are configured to receive an end means such as the abutment member 80 illustrated in Figure 4. The end means shortens the distance over which foot supports 4a, b slide.
  • the abutment member has protrusions 82 which, when the abutment member is in use, sit in a pair of holes 15.
  • Abutment member 80 also has web portion 84 with which foot support 4b may abut.
  • the pair of holes used is selected based on the desired length of the guide means along which the foot supports should slide. Pairs of holes 15 are preferably spaced along guide means 6b at less than or equal to 150mm intervals, beginning 250mm from turret 10. However, this spacing is an example only and it is to be understood that other spacings may be suitable. Each of these sets of holes is numbered to ensure ease and safety of use and repeatability when desired. For beginners or less flexible users, the abutment member 80 should be retained in a pair of holes 15 which is closer to turret 10 to prevent the foot supports from sliding further apart than the user's flexibility can accommodate. As the user trains using the exercise machine and their flexibility improves, the user will be able to slide the foot supports further apart.
  • the abutment member can be moved into a pair of holes which is further away from the home position.
  • the end means can also be used to shorten the effective length of the guide means to accommodate shorter users or users with shorter legs.
  • the primary purpose of the end means is as a safety feature to minimise injury due to overstretching.
  • pairs of holes may be provided along both guide means 6a, b in an embodiment of the exercise machine in which movement of the foot supports is not linked. Particularly flexible users are unlikely to require use of the end means.
  • the end means illustrated in the drawings may be stored safely in the pair of holes 15 which is furthest from the turret.
  • the abutment member is preferably retained by use of a retractable cable or curly cord. Such retraction does not affect use of the machine and is advantageous because it does not interfere with moving parts during normal use.

Such sensors may include optic and infra red sensors, accelerometers and the like.
  • the senor incorporates a radar device having fixed location, and using one of the foot supports as a reference point for measurement. As the foot support moves, the reference point moves and is detected by the radar sensor.
  • the sensor is calibrated so as to display the distance moved in millimetres, although other dimensions such as inches or centimetres may be used as an alternative.
  • the measurement displayed is actually the distance between the 2 foot supports.
  • the display may indicate the distance moved by one foot support or by both foot supports but displayed separately.
  • the control apparatus is pre-programmed with one or more stretching programs consisting of stretch-and-contract exercises and the user can execute, program, store and/or delete additional stretching programs.
  • a "Program” button may be provided and pressed by the user to toggle through pre-programmed stretching programs. Preferably these are “PNF mode” stretching programs although other modes of stretching programs may also be pre-programmed into the control apparatus. The user may also retain one or more pre-defined programs entered in "manual" mode.
  • Console 20 includes four display regions, 30, 40, 50, and 60. Display regions 30 and 40 enable the user to enter parameters for use in "Proprioceptive Neuromuscular Facilitation (PNF)" stretching mode or “manual” stretching mode respectively.
  • Display region 50 includes four light emitting diodes (LEDs) which are illuminated at different times to indicate whether the user should be assuming, holding or exiting the stretched position or contracting the stretched muscles. Any suitable illumination means may be used as an alternative.
  • LEDs light emitting diodes
  • an audible cue will then sound for 5-15 seconds during which the user holds the first stretched position and contracts the stretched muscles.
  • this audible cue is accompanied by illumination of "contract” LED 52.
  • the sound level of the audible cue can be adjusted using volume adjust controls 63.
  • the "contract" duration may be adjusted according to the user's preference when the control apparatus is programmed with a stretching routine.
  • An audible cue will sound again for 5-15 seconds during which the user holds and contracts the stretched muscles in the third stretched position.
  • the audible cue is accompanied by illumination of "contract" LED 52.
  • buttons in display region 40 are used.
  • the user may set up an individual timing sequence for a simple stretch and hold routine using the following steps. 1. Press “start” button 42 to commence the stretching routine. A 5 second period will follow in which the user stretches into the first position. During this time, “stretch” LED 51 will illuminate. 2. An audible cue will then sound for a pre-programmed length of time adjustable between 5 and 60 seconds signalling for the user to hold the stretch. Preferably this is accompanied by illumination of "hold” LED 53. At the end of the "hold” period, the "manual" routine is complete. 3.
  • An audible cue will then sound for 3 seconds, preferably accompanied by illumination of "end of routine" LED 54 to indicate that the user may now exit the stretched position.
  • Progress meter 61 will display a measurement of the amount of stretch achieved by the user. This value will be retained until such time as reset button 62 or start button 32 or 42 (PNF or manual mode) is depressed.
  • the audible cues may include beeps, tones or a pre-recorded voice providing verbal instructions to "assume a stretched position", “hold the stretched position”, “contract the stretched muscles” and the like.
  • the audible output level may be adjusted using volume adjust controls 63.
  • two numerical displays may be included to show different numerical values indicating respective distances travelled by the foot supports 2.
  • the durations and ordering of "stretch-and-contract" exercises provided in the preceding description are examples only and may be adjusted as necessary.
  • the present invention can be used to improve flexibility as well as strength. Accordingly, the present invention may be used to improve general health and fitness and may also be used to train high level athletes such as those involved in dancing, martial arts, gymnastics, football and the like. The present invention is also suitable for use in rehabilitation.
  • the exercise machine is adaptable for use by users of different stature, age, strength and proportions, and can be adjusted to comfortably stabilise a user when using the exercise machine to perform a front stretch or a side or adductor stretch. It is to be understood that the durations, visual and audible cues and other aspects of the stretching routine are examples only, and various modifications, additions and/or alterations may be made to the parts previously described without departing from the ambit of the present invention as defined in the claims appended hereto.

Abstract

La présente invention a trait à un appareil d'exercice (1) comportant une base (2), une paire de support de pieds (4a, 4b), un moyen de guidage (6a, 6b) pour s'adapter au glissement de la paire de supports de pieds en éloignement et en rapprochement l'un de l'autre et un moyen de support de corps pour la stabilisation d'un utilisateur tourné vers une parmi une pluralité de directions lors de l'utilisation de l'appareil d'exercice. Pour utiliser l'appareil d'exercice, un utilisateur place un pied dans chacun de la paire de support de pieds et fait glisser les supports de pieds en éloignement pour adopter une position tendue dans laquelle les muscles de la jambe sont étirés. Pour sortir de la position tendue l'utilisateur contracte les muscles de la jambe pour faire glisser les supports de pieds en rapprochement.
