Stationary exercise device

Abstract

 An exercise device includes two cranks (30) rotatably coupled to a rear portion (14) of a post (11) and each having a rod (27), two handles (40) having a middle portion pivoted to a front portion (13) of the post (11) with a spindle (12), two foot supports (50) pivotally coupled to the handles (40) and each having a middle portion (51) coupled to the rod (27) of the cranks (30) with a link (52), the front portions (53) of the foot supports (50) may be controlled by the handles (40) and to be actuated as a stepping exerciser when the front portions (53) of the foot supports (50) are stably held in place by the handles (40), and to be actuated as an elliptical exerciser when the handles (40) are swung by the user.

Description

[0001] The invention relates to an elliptical exercise device including a changing moving stroke for working either as a stepping exerciser or an elliptical exerciser.

[0002] Typical stepping exercisers comprise a pair of handles pivotally attached to a base, and a pair of foot supports pivotally coupled to the handles and to be stepped or moved up and down by the users. However, the moving stroke of the exercise devices may not be increased or adjusted.

[0003] The invention provides an exercise device according claim 1 including a changing moving stroke for working as a stepping or elliptical exerciser or for being converted between a stepping exerciser and an elliptical exerciser.

[0004] Further advantageous embodiments are laid down in the further claims.

[0005] In the following the invention will be described in greater detail with reference to an embodiments shown in the drawings.

FIGS. 1, 2 are perspective views of an exercise device;

FIGS. 3, 4 are partial exploded views of the exercise device;

FIGS. 5, 6, 7, 8, 9, 10, 11 are side plan views.

[0006] Referring to FIGS. 1-5, an exercise device 1 comprises a post 11 extended up from a base 10, a spindle 12 disposed on the front portion 13 of the post 11, a wheel 20 attached to the rear portion 14 of the post 11 with a shaft 21, a rotary member 22 attached to the post 11 with an axle 23, a follower 24 attached to the axle 23 and moved in concert with the axle 23 and coupled to the wheel 20 with a sprocket-and-chain, gearing or belt coupling device 25 and driven by the wheel 20. A flywheel 26 is attached to the middle or lower portion of the post 11 with a rod 27 which is coupled to the rotary member 22 with another sprocket-and-chain, gearing or belt coupling device 28 for forming a resistive means or device resist the wheel 20 and the shaft 21.

[0007] Two cranks 30 are secured to the shaft 21 and each include a rod 31 spaced from the shaft 21, two handles 40 include an upper or middle portion 41 attached to the spindle 12 and each include a hand grip 42 for being grasped by the users. Two foot supports 50 each include a middle portion 51 coupled to the rod 31 of the cranks 30 with a link 52 and movable cyclically, a front portion 53 coupled the lower portion 44 of the handles 40, and a foot pedal 54 for supporting the users.

[0008] In operation, the handles 40 may be swung relative to the post 11, and the middle portions 51 of the foot supports 50 may be moved cyclically by the cranks 30, such that the foot pedals 54 of the foot supports 50 may be moved elliptically relative to the post 11 of the base 10. The handles 40 and the front portion 53 of the foot supports 50 may be stably held in place by the users with the hand grips 42 for allowing the foot supports 50 to be stepped and worked as a stepping exerciser. In addition, the swinging movement of the handles 40 may be controlled by the users to control the moving stroke of the foot supports 50 (FIGS. 5-11).

[0009] A coupling device 60 may couple the handles 40 together, and includes a pole 61 attached to the post 11, and two cranks 62 are secured to the pole 61 and each include a rod 63 spaced from the pole 61, and two levers 64 each include one or first or rear portion 65 pivotally coupled to the rod 63 of the cranks 62 and the other or second or front portion 66 pivotally coupled to the middle portions 41 of the handles 40 with a pin 67 which is spaced from the spindle 12, for allowing the handles 40 to be coupled together.

[0010] The wheel 20, the rotary member 22, the follower 24, and the flywheel 26 may be acted as a resisting means or device for applying a resistive or retarding force against the wheel 20 and the shaft 21 and the cranks 30 and the link 52 and the foot supports 50 and the levers 32 and the handles 40. A magnetic retarding device (not shown) may be coupled to the wheel 20 and/or the rotary member 22 and/or the follower 24 and/or the flywheel 26. The handles 40 each include a lower portion 44 coupled the front portion 53 of the foot supports 50 for allowing the moving stroke of the foot supports 50 to be controlled by the users with the handles 40 and for allowing the users to freely and selectively conduct the stepping exercises and/or elliptical exercises without adjusting any mechanism or parts or elements.
