FIG. 1 is a perspective view of the present invention. -
FIG. 2 is an exploded view of the present invention. -
FIG. 3 is a partial cross sectional view of the present invention. -
FIGS. 4 and 5 are schematic views about the operations of the present invention. - In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.
- Referring to
FIG. 1 , an exercise bicycle basically comprises a body (not shown) capable of standing upon a ground. Anouter tube 1 extends from the body. Aninner tube 2 is received in theouter tube 1. A top end of theinner tube 2 is installed with a cushion 9 for carrying a rider. A positioning unit 6 serves to adjust the elevation of theinner tube 2. - With reference to
FIG. 2 , along hole 11 is formed near a top end of theouter tube 1. Theinner tube 2 is received in an innerhollow portion 10 of theouter tube 1. A plurality ofpositioning holes 20 are formed on theinner tube 2. Thepositioning holes 20 are positioned corresponding to thelong hole 11 of theouter tube 1. - The
frame seat 3 can be firmly secured to a periphery of thelong hole 11 of theouter tube 1. Theframe seat 3 has a left wing and aright wing 31 which are symmetrically arranged. Eachwing 31 has apinhole 32 at an upper side thereof and anaxial hole 33 at a lower end thereof. Anotch 35 and around hole 34 aside thenotch 35 are formed at an upper wall connected the right andleft wings 31. Asleeve 42 is placed in thenotch 35. Apin 41 passes through the right andleft wings 31 and thepinhole 32. Apost 43 passes through the twoaxial holes 33.C rings right wings 31 and clamp thepost 43. - The positioning unit 6 is located between the right and
left wings 3 1 for positioning theinner tube 2. The positioning unit 6 is formed with anaxial hole 60. A front upper end of the positioning unit 6 is formed with abuckle bar 62. A rear end of the positioning unit 6 is installed with adriving arm 61. Acam portion 63 is formed at the front lower side of the positioning unit 6 and is in front of theaxial hole 60. Astopper 65 extends from thedriving arm 61. Thepost 43 passes through theaxial hole 60 of the positioning unit 6. Thereby the positioning unit 6 is installed between the left andright wings 31 of theframe seat 3 and thus is rotatable along thepost 43. - A
spring 7 has one end buckled to theround hole 34 of onewing 31 and another end fixed to acap 8. Thecap 8 is screwed to a screw hole 64 at a rear lower end of the positioning unit 6. Thereby the assembly of theinner tube 2,outer tube 1,frame seat 3, and positioning unit 6 is complete. - The
buckle bar 62 of the positioning unit 6 passes through thelong hole 11 and then inserts into one of thepositioning holes 20 of theinner tube 2 so that theinner tube 2 is fixed to a predetermined height. If it is desired to adjust the height of theinner tube 2, namely the height of the cushion 9, thedriving arm 61 of the positioning unit 6 is moved. Then the positioning unit 6 will rotate along thepost 43 so that thebuckle 62 separates from the buckledpositioning hole 20. Thereby the height of theinner tube 2 is adjustable (referring toFIG. 3 ). When theinner tube 2 is adjusted to a predetermined height, the positioning unit 6 is driven along an opposite direction so that thebuckle bar 62 is further buckled to anotherpositioning hole 20 of the inner tube 2 (referring toFIG. 4 ). It is known that when the user sits on the cushion 9 for exercise, theinner tube 2 suffers from a downward pressure. Since the positioning unit 6 has thecam portion 63, when thebuckle bar 62 suffers from the gravitational force of theinner tube 2, the positioning unit 6 will swing along thepost 43. Then thecam portion 63 will tightly resist against the wall of theinner tube 2, as shown inFIG. 5 . Simply, by the pressure from thecam portion 63 of the positioning unit 6, the relative motion between theinner tube 2 andouter tube 1 will be greatly reduced so as to retain in a steady state. In the present invention, to avoid thecam portion 63 not to position theinner tube 2 due to wearing of the cam portion so that theinner tube 2 moves downwards, thestopper 65 can be stopped by thesleeve 42. Thereby the positioning unit 6 can not rotate unlimitedly along a direction illustrated inFIG. 5 and thebuckle bar 62 do not separate from thepositioning hole 20 so as to be retained in a steady state. - Thereby in the present invention, by the
buckle bar 62 to buckle thepositioning hole 20 of theinner tube 2, theinner tube 2 andouter tube 1 will not move relatively so as to have a preferred stability. Furthermore, in the present invention, thecam portion 63 of the positioning unit 6 tightly resists against the wall of theinner tube 2 so as to further increase the stability. - Although this inventions has been described with a certain degree of particularity, it is to be understood that the present disclosure has been mad by may of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter clamed.
