- In co-pending U.S patent application Ser. Nos. 11/152,159 and 11/328,412, the applicant disclosed a foldable exerciser which can simulate a horse-riding action and which can be treaded by a user for performing cycling exercise. In addition, the foldable exerciser can be folded after use. However, it is desirable to have an exerciser that provides a feeling of comfort when in use.
- The object of the present invention is to provide a foldable exerciser which is adjustable to provide a satisfactory feeling of comfort when in use.
- According to this invention, the foldable exerciser includes an elongated main frame having top and bottom ends, and a middle portion interposed therebetween. A prop member has a rest end adapted to sit on a ground surface, and a propping end connected to the middle portion to prop the main frame in a straddle position. A saddle mounting frame includes a front pivot end pivotally connected to the middle portion, an arm segment extending radially from the front pivot end to terminate at a juncture, and a saddle mounting segment extending rearwardly from the juncture such that the juncture is turnable between proximate and distal positions relative to the top end. A saddle is mounted on the saddle mounting segment. An operating unit includes a fulcrum pivotally connected to the top end, and a force end and a weight end at two sides of the fulcrum. A coupler interconnects the juncture and the weight end such that in the straddle position, rearward pivoting movement of the force end toward the saddle mounting segment results in turning of the juncture from the distal position to the proximate position so as to move the saddle mounting segment forward for simulating a horse-riding action. A bracing unit includes lower and upper shanks and a damper member. The lower shank has a lower shank end coupled to the main frame proximate to the bottom end. The upper shank has an upper shank end distal from the lower shank end so as to brace the saddle mounting segment when the saddle mounting segment is in the distal position, and is telescopically fitted to the lower shank such that the upper shank end is movable relative to the lower shank along a lengthwise axis thereof. The damper member is disposed to bias the upper shank end away from the lower shank end such that when the saddle mounting segment is moved forward to simulate the horse-riding action, an impact generated as a result of plunging of the saddle mounting segment toward the upper shank end is counteracted by the biasing force.

FIGS. 2 and 7 , the user can sit on thesaddle 32 and grip thehandlebars 42 while treading thepedals 52 for performing cycling exercise. The user may also pull thehandlebars 42 rearwardly so that thesaddle 32 is raised and turned toward thehandlebars 42 to simulate a horse-riding action. It is noted that when thesaddle mounting segment 314 is pressed to plunge to theupper shank end 241, the impact therebetween is counteracted by the biasing force of thecoil spring 26, thereby providing a damping effect. In addition, as shown inFIG. 4 , to meet the user's requirement, thefirst locking unit 27 can be released to permit adjustment of the position of themount 23 so as to vary the height of theupper shank end 241 and thesaddle mounting segment 314. As shown inFIG. 5 , thethird locking bolt 44 can also be released to permit adjustment of the secondconnected end 438 relative to the firstconnected end 437 so as to vary the distance between thehandlebars 42 and thesaddle 32 to accommodate different users. - Referring to
FIGS. 3, 5 , and 8, to fold the exerciser, thesecond locking bolt 22 and thefastening unit 55 are released, and the second coupledend 436 is disengaged from theweight end 413 such that the bracingunit 2, thesaddle unit 3, theoperating unit 4, and theprop member 53, as well as thepedaling unit 5, can be turned and collapsed toward themain frame 1. - While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretations and equivalent arrangements.
