Disclosed is a foldable exerciser horse which has simple and collapsible structure. A user can use it as an exerciser bike while enjoys the fun of riding a horse.

Description:
BACKGROUND OF THE INVENTION 
     There are various types of exerciser bikes available in the market. However, most of these conventional exerciser bikes are bulky and are of complicated structure, and they are not always designed to be foldable. Also, few of these conventional exerciser bikes can provide the fun of riding a horse. 
     SUMMARY OF THE INVENTION 
     It is therefore a primary object of the present invention to provide an exerciser horse which has a simple and foldable structure, and can also provide a user with the fun of riding a horse. 
     The foldable exerciser horse according to the present invention mainly includes two pivotally connected supporting frames, a seat assembly supported on top of the supporting frames, and a handle-bar assembly connected to a top front of the supporting frames. The seat assembly is connected to the handle-bar assembly by means of a link such that pull or push of the handle-bar by a user sitting on the seat will cause the seat assembly to move upward and forward or downward and backward, just as in riding a horse. The foldable exerciser horse provides the user with not only the fun of riding but also the effect of exercise.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Please refer to FIGS. 1 and 2. The present invention is a foldable exerciser horse including an upper supporting frame 1, a lower supporting frame 2, a handle-bar assembly 4, and a seat assembly 6. 
     The upper supporting frame 1 includes two parallel members 10, 101. The members 10, 101 are pivotally connected at their top ends to the handle-bar assembly 4 near a middle neck portion thereof by means of a first shaft 3 which serves as a fulcrum so that the handle-bar assembly 4 may be pivotally moved about the shaft 3 relative to the seat assembly 6, and fixedly connected at their lower ends to a transversely extended bar 11 which is positioned on the floor to support the members 10, 101 and has an anti-slip means 12 provided to each end thereof. A pair of lugs 110, 120 are provided on the members 10, 101, respectively, near a top middle portion thereof for a first pin 32 to extend therebetween. A pillar 102 is connected between the members 10, 101 by a second shaft 31, such that when the foldable exerciser horse of the present invention is in an extended state, the pillar 102 just projects upward from and between the members 10, 101 to be stopped by and in front of the pin 32 extending between the lugs 110, 120 to abut against the pin 32. A pad 1021 is attached to a top end of the pillar 102 to receive and support the seat assembly 6. A third shaft 33 extends between the members 10, 101 at a position adequately in front of the second shaft 31 for the lower supporting frame 2 to press against. A cylindrical member 35 with a second pin 34 axially inserted therein is fixed to a bottom side of the members 10, 101 slightly above or in front of the shaft 33. When the upper and the lower supporting frames 1, 2 extend relative to each other, the lower supporting frame 2 shall be stopped by the cylindrical member 35 without further extending forward, so that the lower supporting frame 2 is firmly held between the third shaft 33 and the cylindrical member 35 without shifting. A fourth shaft 36 extends between the members 10, 101 at a position still higher than the cylindrical member 35 and the pin 34 to pivotally connect the seat assembly 6 thereto, serving as a fulcrum for the seat assembly 6 to turn relative to the upper supporting frame 1. 
     The lower supporting frame 2 includes an upward extended pillar portion 21 extending between the members 10, 101 as well as between the shaft 33 and the cylindrical member 35, and a transversely extended rod 11&#39; connected to a lower end of the pillar portion 21. Anti-slip means 12 are also attached to two ends of the rod 11&#39; for the lower supporting frame 2 to stably position on the floor. The pillar portion 21 has a laterally projected part 22 near a top end thereof so that the part 22 is stopped by and supported on the shaft 33 when the lower supporting frame 2 is extended relative to the upper supporting frame 1, serving as a fulcrum and together with the cylindrical member 35 to enable the lower supporting frame 2 to locate without shifting after it is extended. 
     The seat assembly 6 includes a top saddle 60 and an arm member 61 having one rear end connected to a bottom side of the top saddle 60 and a downward bent front end pivotally connected to and between the upper supporting frame 1 at a higher position thereof by the fourth shaft 36. The bent front end of the arm member 61 has two lugs 62 projected from a top surface thereof, such that a link 5 is connected to the two lugs 62 by a fifth shaft 37 extending between them. A lower end of the link 5 is then further connected to the handle-bar assembly 4, so that the seat assembly 6 can move along with the shifted handle-bar assembly 4. 
     The handle-bar assembly 4 mainly includes a handle-bar grip 40, an inner stem 41, and an outer stem 42. The inner stem 41 can be slidably received within the outer stem 42, and be fixed relative to the outer stem 42 at a desired extended length with a locating bolt 43 provided near a top end of the outer stem 42. A laterally projected part 44 projects from near the top of the outer stem 42 into and between the top ends of the members 10, 101 and be pivotally connected thereto by means of the first shaft 3. Two connecting plates 421 are provided to the outer stem 42 at a position lower than the projected part 44, such that the link 5 is pivotally connected at its lower end to and between the two connecting plates 421 by means of a third pin 38. Whereby, the backward or forward movement of the stems 41, 42 actuated by a user shall cause the seat assembly 6 to shift forward or backward at the same time via the link 5 connected between the two assemblies 4 and 6. The handle-bar grip 40 has two curved ends which are comfortably gripped by the user. A pair of foot-rests 45 and a pair of pedals 46 are provided near and at a lower end of the outer stem 42, respectively, forming two angularly different positions for resting the user&#39;s feet. 
     The use of the foldable exerciser horse of the present invention is illustrated in FIG. 2. The user (not shown) is seated on the top saddle 60 with his or her feet positioned on the foot-rests 45 or the pedals 46 and hands gripping the handle-bar grip 40. When the handle-bar grip 40 is pulled back toward the user, the seat assembly 6 is brought to turn upward about the fifth shaft 37 relative to the upper supporting frame 1, just as in riding a horse. 
     To fold the exerciser horse of the present invention for storage when it is not in use, simply remove the pins 32, 34, and 38 from their original positions, and the whole exerciser horse can be collapsed to a reduced volume, as shown in FIG. 3, for convenient storage.
