Description
~6~3~3t This inven-tion relates generally to bicycle--type gymnastic apparatus. While bicycle-type gymnastic apparatus has been known in the art, the present apparatus presents an improved approach to multi-use and adjustable apparatus.
Generally speaking, in accordance with the invention, bicycle-type gymnastic apparatus is provided, which may be used to perform both pedaling and rowing exercises. The aipparatus has a frame, a seat mounted on the frame, and a member pivotably mounted on the frame with handle bars at the upper end and pedals at the lower end. The pedals drive a rotating cam which is biased into contact with a bearing by means of an adjustable spring. Thus, when the pedals are turned the action of the cam and the bearing causes the pivotably mounted member to pivot fore and aft and thereby create a rocking effect of the handlebars. The operator may adjust the degree of effort required to turn the pedals by means of a spring mounted brake shoe contacting a drum which rotates with the pedals.
;~ The apparatus may also be llsed to perform rowing exercises.
Accordingly, it is an object of this invention to provide an improved gymnas~ic apparatus which may be used to perform pedaling exercises.
Another obiect is to provide an improved gymnastic apparatus which may be used to perform rowing exercises. -A further obiect of the invention is to provide an improved gymnastic equipment that is easily adaptable to changing from a pedalling mode to a rowing mode.
Still other objects and advantages of the invention will in part be obvious and will in part be apparent from the specification.
Accordingly, what is being broadly claimed herein is ~ -"~
6,~'738 a bicycle-type gymnastic apparatus comprising a frame with a seat, mounted on the ~rame, and a member pivotally moun-ted also on the frame, this member having pedals and a cam rotatably mounted at one of its ends and handle bars mounted at the other of its ends, this cam being connecte~ to rotate with the pedals. A cam follower is mounted on the frame and a resilient mechanism, carried by the frame, biases the cam into engagement with the cam follower so that rotation of the cam causes the handle bar member to oscillate about its pivot.
There is further provided means Eor preventing contact between the cam and the cam follower to prevent oscillation of the handle bar member by the cam and to allow the member to pivot by manual operation of the handle bars. This contact preventing means includes a rod mounted to the member, a peg ` mounted on the frame, the rod having a first end and a second end, the first end being located on the member proximate to the handle bars. Also the rod is displaceable between a first position, in which its second end makes contact with the peg to prevent the cam from contacting the cam followex, to a second position in which the second end avoids contact with the peg to permit the cam to contact the follower to thereby permit ` P
oscillati~n o~ the member by the cam and allow the user to adjust the mode of operation while remaining seated.
A be~ter understanding of the invention will be had by the description that follows of a pre~erred embodiment thereof, having reference to the appended drawings wherein:
Fig. 1 is a side elevational view of the gymnastic apparatus of the present lnvention, with a frame member removed to show the components;
` Fig. 2 is a partial perspective view of the biasing spring tension control mechanism;
Fig. 3 is a rear elevational view of the gymnastic '' ~ - 2 apparatus of the present invention; and Fig. 4 is a side elevational view, at an enlarged scale, of the braking mechanism of the present invention.
Referring now to Fig. 1 the gymnastic apparatus has a supporting frame 30 comprising a pair of tubular members 15 arranged in the shape of an inverted "V", whose free ends curve outwardly establishing four points of sup-port or feet 31. Tubular members 15 have attached thereto plates 32 to support elements to be described below. Secured to frame 30 is a post 1 upon which a seat 2 is mounted. A
roller bearing or cam follower 3 is mounted at the lower end of post 1.
A member or shaft 7 is pivotably mounted to the frame at 9 and to the upper end of shaft 7 is mounted handle bars 8. ~

3~)62~313 The lower portion of shaft 7 has a bearing socket (not shown) 2l in wich is rotatably mounted an axle 4. Mounted on axle 4 are ' , !1 a polygonal cam plate 11 and pedals 33 which drive the cam ¦I plate. A spring 12 attached between shaft 7 and frame 30 biases 2~
¦~ cam plate 11 into contact with bearing 3. When pedals 33 are i rotated, the cam action of cam plate 11 against bearing 3 ji causes shaft 7 and its attached handlebars 8 to move fore and ' aft in the direction of the arrows shown in Fig. 1. Such ¦ movement provides exercise and relaxation for the operator seated on seat 2 and gripping handlebars 8.
j As described above~ spring 12 is attached at one end I to shaft 7 and at the other end to frame 30. The attachment ¦I to frame 30 is through a lever 14 which provides for adjustment ~ `
¦ o-E the spring tension. As shown in Figs. 1, 2 and 3, lever 14 I is pivotably mounted to frame 30 through plates 34 by means ¦ of pin 13 . Lever 14 passes through an anchoring plate 17, which I is mounted between frame tubes 15. Lever 14 has a series of steps 35 which ride in a series of not~hes 16 cut in anchoring plate 17.

Support 26 is mounted at one end to a fixed peg 24 secured to an ear 36 mounted on shaft 7 and at the other end to an adjustable plate 21 via a spring 27. Plate 21 has elongated openings 37 through which rods 20 and 22 extend, with rods 20 and 22 being fixed to shaft 7. Attached to plate 21 is a threaded socket 28. Rod 19 is threaded into threaded socket 28 Rod 19 is mounted through plate 38 on shaft 7 so that it may be rotated abou~ its longitudinal axis. As rod 19 is so rotated, threaded socket 28 and attached-plate 21 move along member 7.
As plate 21 ascends, the tension of spring 27 increases, which causes an increase in braking force and a consequent increase in the amount of effort required to rotate the pedals. Con-versely, when rod 19 is rotated in the opposite direction, plate 21 descends along member 7 and the effort required to rotate the pedals decreases The present apparatus may al~o ~e used for rowing exercises. This is accomplished by means of a rod 6 which is mounted to be slidable along shaft 7 through plate 38. Rod 6 has an ex~ension 1~, which contacts a peg 5 mounted plate 32 when rod 6 is moved downwardly. Thus~ the extension lO of rod 6 is interposed between peg 5 and shaft 7 and thereby prevents shaft 7 from pivoting sufficiently for cam plaie 11 to contact bearing 3. In this position7 shaft 7 will not pivot fore and aft' when the pedals are rotated. The operator may then perform rowing" exercises by pulling back against the handlebars 8.

I When shaft 7 is pulled toward the operator (toward post 1), the ,i' movement of member 7 will be opposed by biasing spring 12 and, ¦I since the tension of spring 12 is adjustable by the use of ¦~ lever 14, as described above, the user may adjust the amount of i effort required to perform the rowing exercises. Foot-pegs 18 ¦1, are mounted on tubular members 15 ~o facilitate the rowing exercises. Thus, the present invention allows the changeover from pedalling to rowing exercise~s by the simple movement of rod 6.
Iii It will thus be seen that the objects set forth above, ¦~ among those made apparent from the preceding description, are ¦¦ e~Eici.ently attained and, since certain changes may be made in the above construction without departing from the spirit and I scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings j~ shalL be interpreted as illustrative and not in a Limi~ing sense.
