Abstract
A seated exercise apparatus comprises a frame having a seat attached to the frame. A pair of opposed cranks are rotatably coupled to the frame such that they rotate about a first axis. A first end of each of a pair of elongated members is rotatably connected to the frame at a respective pivot joint. A second end of each of the elongated members is connected to a respective. The pivot joints are located outside of a plane of motion of their respective right and left pedals, such that the apparatus can fit within a more compact form factor, especially in a longitudinal dimension. The pedals move in a reciprocating path having an elliptical shape, in which the major axis is more vertical than horizontal, giving a more up and down, natural, pedal motion.

DETAILED DESCRIPTION OF THE INVENTION
(13) Referring to
(14) A seat 6 is attached to the seat riser. The seat 6 and seat riser 42 may be configured to adjust the seat position. In this example, the seat riser 42 includes a plurality of positions which adjust the seat's vertical and horizontal position so that the seat 6 can be adjusted to fit the particular user. The seat 6 may include a seat back. The seat 6 is oriented to position the user in a substantially upright seated position.
(15) A first crank 7 and second crank 8, each having a first end, and a second end are arranged substantially opposed to each other and positioned below and distal the seat 6. The first end of the first and second cranks 7, 8 are rotatably coupled to the frame 1 at the crank riser 44, such as through an axle, sleeve and bearings, or other suitable structure, such that the first and second cranks 7, 8 rotate about a first axis 2 defined by the axle, where the first axis 2 is substantially perpendicular to the longitudinal axis of the apparatus 30. The first crank 7 and second crank 8 are typically disposed on opposing sides of the axle. The first and second cranks 7, 8 may be rotatably coupled to the frame through attachment to pulley 3 which is coupled to the frame using, for example, an axle, sleeve, and bearings, or other suitable structure.
(16) A flywheel 22 is rotatably coupled to the frame 1 at the crank riser 44 through a pivot axis 23, below and slightly proximal of the pulley 22 and first and second cranks 7, 8. The flywheel 22 is operably coupled to the pulley 3 by a belt 4. The belt 4 may be a chain, a belt, or other suitable, flexible engagement. An adjustable load resistance device 32 is operably coupled to the flywheel 22, and in turn to the pulley 3, to provide an adjustable load resistance on the pulley 3. The load resistance device 32 may use magnetic resistance, friction, an alternator, a fan, or other suitable adjustable load resistance mechanism. The load resistance device 32 may be operably coupled to a user console 24 configured to adjust the load resistance.
(17) A first elongated member 15 having is provided on the first side of the apparatus 30. The first elongated member 15 includes a first end 34, a second end 38, and a medial portion 36. The first end 34 is positioned generally proximal of a seated user and to the outside of the seat 6. The first end 34 has a handle 20 for a user to grip with their right hand. The first elongated member 15 extends from the handle 20 in a forward direction toward the proximal end of the apparatus 30. The medial portion 36 of the first elongated member 15 is positioned proximal the seat 6 and extends generally vertically downward so that it provides room for a user to mount the seat 6 without being hindered by the first elongated member 15 or the handle 20. The medial portion 36 is rotatably connected to the frame 1 at the front riser 40 at a second axis 19 which is transverse to the longitudinal axis, such that the first elongated member 15 rotates about the second axis 19. The first elongated member 15 then extends from the generally vertical medial portion 36 through a curved portion and along a generally horizontal portion to the second end 38, which is positioned near the bottom of the apparatus 30.
(18) A second elongated member 16 is disposed on the second side of the apparatus 30, and is a mirror image of the first elongated member 15, in both structure and coupling to the apparatus 30. The second elongated member 16 includes a first end 50, a second end 54, and a medial portion 52. The first end 50 is positioned generally proximal of a seated user and to the outside of the seat 6. The first end 50 has a handle 21 for a user to grip with their right hand. The second elongated member 16 extends from the handle 21 in a forward direction toward the proximal end of the apparatus 30. The medial portion 52 of the second elongated member 16 is positioned proximal the seat 6 and extends generally vertically downward so that it provides room for a user to mount the seat 6 without being hindered by the second elongated member 16 or the handle 21. The medial portion 52 is rotatably connected to the frame 6 at the front riser 40 at the second axis 19, such that the second elongated member 16 rotates about the second axis 19. The second elongated member 16 then extends from the generally vertical medial portion 52 through a curved portion and along a generally horizontal portion to the second end 54, which is positioned near the bottom of the apparatus 30.
(19) In another embodiment (not shown in the figures), the seated exercise apparatus 30 can be provided without handles 20 and 21 on the elongated members 15 and 16. In this embodiment, the elongated members 15 and 16 may end at the medial portions 36 and 52, respectively, or they may even end at the connection to the second axis 19. The seated exercise apparatus provide a leg exercise, only. In another aspect, the handles 20 and 21 may be removably attached to the elongated members 20 and 21, such that they could be installed if the user wants to use them, or removed if the user does not want to use them. The removable handles 20 and 21 include the upper portion of the elongated members 15 and 16, including the first ends 34 and 50. Then, the handles 20 and 21, and the upper portion of the elongated members 15 and 16 are removably coupled to the elongated members 20 and 21 at or proximate the connection to the second axis 19. For example, the handles 20 and 21 may each include a tube having a lower end that is coaxially received (inside or outside) by the upper end of the elongated members 15 and 16. A locking device can be used to lock the handles 20 and 21 in place on the elongated members 15 and 16. The locking device could be a spring loaded pin and detent mechanism, a locking screw, or other suitable device.
(20) A first pedal arm 9 having a first end 60, a second end 62, and a pivot portion 64 is disposed on the first side of the apparatus 30, with the first end 60 distal of the first elongated member 15 and the second end 62 proximal of the second end 38 of the first elongated member 15. The first end 60 of the pedal arm 9 is rotatably connected to the second end of the first crank 7 at pivot 11. The pivot portion 64 of the first pedal arm 9 is rotatably connected to the second end 38 of the first elongated member 15 at pivot 17. A first pedal 13 configured to support the right foot of the user is operably connected to the first pedal arm 15 proximate the second end 62 of the first pedal arm 9. The location of the pivot 17 relative to the first pedal 13 will determine the up and down motion of the first pedal 13, and can be changed according to the present invention. For example, if the pivot 17 is located distal of the first pedal 13, the first pedal 13 will have a reciprocating motion up and down in a generally elliptical path. If the first pedal 13 is placed directly over the pivot 17, then the first pedal 13 will move in a reciprocating motion up and down motion in an arcuate path. The more the pivot 17 is moved distally of the first pedal 13, the more elliptical the pedal path will be. Thus, a downward force on the first pedal 13 causes the first crank 7 to rotate in a counterclockwise direction about the first axis 2, in turn the first elongated member 15 rotates about the second axis 19, and the first pedal 13 moves in a steep up and down reciprocating motion (which may be arcuate or elliptical). The rotation of the first elongated member 15 about the second axis 19 causes the handle 20 to move through a reciprocating arcuate motion, which provides for coordinated movement of the first pedal 13 and the handle 20 (i.e. a complete cycle of the first pedal 13 corresponds to a complete cycle of the handle 20).
(21) Likewise, a second pedal arm 10 having a first end 70, a second end 72, and a pivot portion 74 is disposed on the second side of the apparatus 30, with the first end 70 distal of the second elongated member 16 and the second end 72 proximal of the second end 54 of the second elongated member 16. The first end 70 of the second arm 10 is rotatably connected to the second end of the second crank 8 at pivot 12. The pivot portion 74 of the second pedal arm 10 is rotatably connected to the second end 54 of the second elongated member 16 at pivot 18. A second pedal 14 configured to support the left foot of the user is operably connected to the second pedal arm 16 proximate the second end 72 of the second pedal arm 10. The location of the pivot 18 relative to the second pedal 14 will determine the up and down motion of the second pedal 14, and can be changed according to the present invention. For example, if the pivot 18 is located distal of the second pedal 14, the second pedal 14 will have a reciprocating motion up and down in a generally elliptical path. If the second pedal 14 is placed directly over the pivot 18, then the second pedal 14 will move in a reciprocating motion up and down motion in an arcuate path. The more the pivot 18 is moved distally of the second pedal 14, the more elliptical the pedal path will be. Similar to the first pedal 13 described above, a downward force on the second pedal 14 causes the first crank 8 to rotate in a clockwise direction (when facing the first crank 8) about the first axis 2, in turn the second elongated member 16 rotates about the second axis 19, and the second pedal 14 moves in a steep up and down reciprocating motion (which may be arcuate or elliptical). The rotation of the second elongated member 16 about the second axis 19 causes the handle 21 to move through a reciprocating arcuate motion, which provides for coordinated movement of the second pedal 14 and the handle 10.
(22) Referring now to
(23) The apparatus 30 is configured such that the major axis of the reciprocating path of the first and second pedals 13, 14 is substantially vertical, and preferably at an angle of greater than 45 degrees to horizontal (or the floor) or 60 degrees to horizontal, or at an angle of greater than 70 degrees horizontal, or at an angle of greater than 80 degrees to horizontal (wherein vertical to horizontal is 90 degrees). This more vertical up and down motion of the pedal 13, 14 provides a more natural motion and creates less stress on the joints than the devices described above in which the pedals travel on a more horizontal path as the user is in a reclined position. Alternatively, the apparatus 30 may provide a more recumbent path in which the major axis of the path of the first and second pedals 13, 14 is at an angle of 45 degrees or less to horizontal (or the floor).
(24) During operation the user sits in a generally upright position with their body supported by seat 6. The user applies force to the first and second pedals 13, 14 resulting in a foot motion that is generally reciprocating. First and second pedals 13, 14 articulate in a manner that allows plantar flexion in the lower pedal position and dorsi flexion in the upper pedal position. The first and second handles 20, 21 move in an arcuate motion during operation of the first and second pedals 13, 14. As all of the moving parts are coupled at least indirectly to the rotation of the pulley 3, the motion of the first and second pedals 13, 14 and the first and second handles 20, 21 are coordinated.
(25) The first and second pedals 13, 14 throughout their motion are located proximal of the seat 16. Thus, it can be seen that the exercise apparatus 30 places less stress on the user's knees and is easily accessible for older users. Moreover, the apparatus 30 uses relatively simple pivot mechanisms, making the device easy to manufacture and assemble.
(26) Turning now to
(27) The major differences in the embodiment of
(28) Beginning with a description of the invertible handles shown in
(29) Similarly for the second adjustable handle 99 on the other side of the apparatus 30, the first end 50 of the second elongated member 52 includes a slider tube 97, an adjustment pin 98 and a first adjustable handle 99. The first adjustable handle 99 has a tubular portion 85, a vertical grip 100 (preferably oriented within 30 degrees or less to vertical) and a horizontal grip 101 (preferably oriented within 30 degrees or less to horizontal) which allows the user to hold the first adjustable handle 99 in different positions. The tubular portion 85 is slidably received within the slider tube 97 to connect the second adjustable handle 99 to the first end 50 of the second elongated member 52. The adjustment pin 98 releasably locks the second adjustable handle 99 in a set position to the first end 50 of the second elongated member 52. Again, other suitable locking devices may be used in place of the adjustment pin 98, such as a pin and detent mechanism.
(30) As shown in
(31) As shown in
(32) As shown in
(33) Turning now to
(34) As explained below, the seated exercise apparatus 200 of
(35) In other words, the first pivot joint 36 of the first elongated member 15 is located to the right side (the directional terms right, left, forward and backward are relative to the orientation of a person seated facing forward in the seat of the apparatus) of the plane of motion of the entire first pedal 13. In this way, the first pedal 13 may extend forward of the first pivot joint 109 without hitting or interfering with the first elongated member. Similarly, the medial portion 52 of the second elongated member 16 is rotatably connected to the frame 201 at a second pivot joint 110 which is located to the outside of the plane of motion of the entire second pedal 14. Again, in other words, the second pivot joint 110 of the second elongated member 16 is located to the left side of the plane of motion of the entire second pedal 14, such that the second pedal 14 may extend forward of the second pivot joint 110 without hitting or interfering with the second elongated member.
(36) In order to provide a compact overall form factor, the first and second pivot joints 109 and 110 may also be within a transverse projection of the path of the entire respective pedals 13 and 14. The transverse projection of the path of the entire pedal is a projection perpendicular to the plane of the path of the entire pedal. This may be better understood by visualizing the entire area covered by the motion of a cross-section or outside surface of the entire first pedal 13. This area is a two-dimensional shape lying in a vertical plane (i.e. a plane parallel to the paper in the side view of
(37) The frame 201 is specifically configured to be routed to the outside of the plane of motion of the first and second pedals 13 and 14 to provide a frame structure for the first and second pivot joints 109 and 110 to be located to the outside of the plane of motion of the pedals 13 and 14. More specifically, the frame 201 has a lower cross bar 116 that extends transverse to the longitudinal axis of the apparatus 200. The lower cross bar 116 extends to the outside of the plane of the pedals 13 and 14 on each side of the apparatus 200. Then, a right front riser 114 extends upward from the lower cross bar 116 on the right side, and a left front riser 112 extends upward from the lower cross bar 116 on the left side. The right front riser 114 and left front riser 112 extend up to the location of the first pivot joint 109 and second pivot joint 110, respectively. The upper end of the right front riser 114 and left front riser 112 are then connected to a u-shaped support bar 118. The u-shaped support bar 118 is also connected to a rear structure of the frame 201, such as the frame structure housing and supporting the flywheel 22, the load resistance device 32, and the seat riser 42, among others.
(38) While embodiments of the present invention have been shown and described, various modifications may be made without departing from the scope of the present invention. The invention, therefore, should not be limited, except to the following claims, and their equivalents.
