Description

Compound bicycle exercise device {COMPOUND BICYCLE EXERCISING DEVICE}

The present invention relates to a composite bicycle exercise apparatus, and more particularly, a composite bicycle having a coupling device (or transmission device) for rotating (or driving) a spindle by pushing forward or pulling a handle stem forward. It relates to an exercise device.

In general, a compound bicycle exercise device uses a pedal to rotate a transmission box and a handle driven by a foot inward or outward, and a user performs a pedaling or cycling exercise and a hand-controlled exercise. And a handle connected to the axis of rotation to the transfer box.

For example, Lee's US Patent No. 4,660,826 drives a pair of pedals and universal joints provided to be rotated or driven by the user to drive the saddle supporter and to move forward and backward, with a rotating bush on its output shaft. One of the general composite bicycle exercise apparatus including a transmission box which is operated by a pedal to make a is disclosed. In addition, a number of connecting rods may connect universal joints to both handles to rotate the handle inward and outward.

However, since the handle is directly connected to the saddle support at the same time, it can be driven forward and backward at the same time while the user is pulling, moving or driving, and the handle is selectively pulled by the user to drive the general compound bicycle exercise device. It may not be pushed or manipulated.

Petersen US Patent No. 5,992,253 are provided to transform the reciprocating motion into a unidirectional rotational movement and to drive the shaft when two pinions and two racks mounted on two one-way clutches are selectively activated. Another general compound bicycle exercise device is disclosed that includes two racks that engage each pinion. The racks are coaxially connected with the two handle or exercise arms, respectively, to be driven or manipulated by the handle or the movement arm.

However, since the rack must be driven in the driving direction and / or in the opposite direction at a speed fast enough to catch up with the axis, the handle must also be driven, rotated or steered at a speed fast enough to catch up with the axis, and the handle itself is operated by the user. Cannot be properly controlled.

The present invention is directed to alleviating and / or eliminating the above problems of a general compound bicycle exercise device.

Two belts, gears, chains or engaging members 37, 38 are provided and attached to each rotating member 35,36 to couple the rotating members 35,36 to other parts or elements described below. Can interlock.

The combined bicycle exercise apparatus 10 has two distal ends 41 and has a spindle 40 provided or attached to or supported by the base 11 as rotatably attached to the frame 18 of the base 11. Further comprising, rotatably attached on each distal end 41 of the spindle 40 with unidirectional bearings 44, 45 (FIGS. 5 and 6), barrel 34, rotating members 35, 36. , Through the engaging members (37, 38) and the follower (42, 43) for the follower (42, 43) to rotate about the spindle 40 by the handle bars (30, 31), 37 and 38 further comprise two sprockets, gears, pulleys, rotating members or followers 42 and 43 connected to the rotating members 35 and 36.

As shown in FIGS. 5 and 6, the unidirectional bearings 44, 45 for the followers 42, 43 allow the spindle 40 to be selectively rotated and driven by the followers 42, 43. It is provided to make it possible. However, while the spindle 40 is required to be continuously rotated and driven by the followers 42 and 43 in the active direction, the handle bars 30 and 31 are reciprocated and moved forward and backward or between opposite directions to the active direction. Will optionally rotate about the axis of rotation 25.

In order for the spindle 40 to be continuously rotated and driven by the driven parts 42 and 43 in the driving direction by rotating the front and rear or optionally the handlebars 30 and 31, the lever 26 is driven by the base 11. And the lever 26 is rotatably attached to its free end (FIGS. 2-4, 7-8) or the base 11 Directly rotatably attached to the frame 18 of the frame 18, engaged with the engagement member 37, the spindle 40 being arranged between the rotation member 35 and the rotational element 27, and / or the engagement element. A sprocket, pulley, or rotating element arranged to engage over the rotating member 35 and for engaging the follower 42 to allow the spindle 40 and the rotating member 35 to rotate in different directions. And (27).

For example, as shown in FIG. 8, when the rotating member 35 is rotated counterclockwise by the handle bars 30 and 31, the spindle 40 is rotated by the rotating member 35 and the rotating element 27. And by the follower 42, in the active or clockwise direction; As shown in FIG. 7, the spindle 40 can also be rotated in the active or clockwise direction by the other rotating member 36 and the other follower 43 and the other engaging member 38, so that the spindle 40 can be rotated. ) Can be continuously rotated and driven by the followers 42, 43 in the active direction by rotating the handlebars 30, 31 forward or rearward or optionally.

In operation, as shown in FIGS. 7 and 8, the handlebars 30, 31 can be rotated about the axis of rotation 25, continuously rotating and driving the spindle 40 in the active direction, and It can be pulled and pushed towards the user and the seat 21 in a reciprocating motion to train the upper muscles. Thrust bearings 46 preferably provide unidirectional bearings 44 and 45 to properly separate the followers 42 and 43, respectively, and to prevent the followers 42 and 43 from operating or contacting each other. And is preferably provided and arranged between the follower 42 and 43 (FIG. 6).

As shown in FIGS. 3-4 and 6-8, the other follower, weight, or wheel 47 also has a handlebar 30 through which the barki 47 passes through the follower 42, 43 and the spindle 40. 31 may be provided and fixed on the spindle 40 to be moved and rotated. The wheels 47 then cause the wheels 23 to be rotated and actuated by the wheels 47 so that the wheels 23 apply or provide resistance against the spindle 40 and the handlebars 30 and 31. It may be connected to the wheel 23 by means of a belt, gear arrangement, chain or coupling element 48 (FIG. 4).

The lever 50 is also provided on the frame 18 of the base 11 so as to be rotatably fixed or attached, and the coupling member 38 and the spring member 52 straighten or harden the coupling member 38. The engagement member 38 is sufficiently engaged with the engagement member 38, and the engagement member 38 is prevented from falling from the rotation member 36 and the follower 43.
