Description

    FIELD OF THE INVENTION
  • The present invention relates to bicycles, and in particular to an elevational adjusting device of an exercise bicycle, wherein by a buckle bar to buckle the positioning hole of the inner tube, the inner tube and outer tube will not move relatively so as to have a preferred stability. Furthermore, a cam portion of the positioning unit tightly resists against the wall of the inner tube so as to further increase the stability.
  • BACKGROUND OF THE INVENTION
  • In the prior art exercise bicycle cushion, the inner tube and outer tube thereof are extendable and compressible so as to adjust the height of the inner tube. Then a pin is fixed to a positioning hole of the inner tube, so as to adjust the height of the cushion. The prior art way is used for a long time. However the prior art cannot firmly secures the inner tube to the outer tube so that as it is used for a long time or a great force is applied to the cushion, the inner tube will move relative to the outer tube so that the elevation of the inner tube is changed.
  • SUMMARY OF THE INVENTION
  • Accordingly, the primary object of the present invention is to provide an elevational adjusting device of an exercise bicycle, wherein by a buckle bar to buckle the positioning hole of the inner tube, the inner tube and outer tube will not move relatively so as to have a preferred stability. Furthermore, in the present invention, a cam portion of the positioning unit tightly resists against the wall of the inner tube so as to further increase the stability.
  • To achieve above objects, the present invention provides an elevational adjusting device of an exercise bicycle. The bicycle has a body capable of standing on the ground. The body is movable by a treading operation. A cushion of the bicycle is adjustable. The elevational adjusting device comprises an outer tube having a hollow inner space and a long hole; an inner tube being installed with a cushion at a top thereof; the inner tube having a plurality of positioning holes which are positioned corresponding to a position of the long hole of the outer tube; a frame seat fixed to the outer tube; and a positioning unit having a post; the positioning unit being positioned to the frame seat; the positioning unit having a buckle bar capable of being buckled to one of the positioning holes of the inner tube; a driving arm; and a cam portion capable of resisting against an wall of the inner tube.
  • Further objectives and advantages of the present invention will become apparent from a careful reading of a detailed description provided hereinbelow, with appropriate reference to accompanying drawings.
  • BRIEF DESCRIPTION OF THE DRAWINGS
  • 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.
  • DETAILED DESCRIPTION OF THE 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. An outer tube 1 extends from the body. An inner tube 2 is received in the outer tube 1. A top end of the inner tube 2 is installed with a cushion 9 for carrying a rider. A positioning unit 6 serves to adjust the elevation of the inner tube 2.
  • With reference to FIG. 2, a long hole 11 is formed near a top end of the outer tube 1. The inner tube 2 is received in an inner hollow portion 10 of the outer tube 1. A plurality of positioning holes 20 are formed on the inner tube 2. The positioning holes 20 are positioned corresponding to the long hole 11 of the outer tube 1.
  • The frame seat 3 can be firmly secured to a periphery of the long hole 11 of the outer tube 1. The frame seat 3 has a left wing and a right wing 31 which are symmetrically arranged. Each wing 31 has a pinhole 32 at an upper side thereof and an axial hole 33 at a lower end thereof. A notch 35 and a round hole 34 aside the notch 35 are formed at an upper wall connected the right and left wings 31. A sleeve 42 is placed in the notch 35. A pin 41 passes through the right and left wings 31 and the pinhole 32. A post 43 passes through the two axial holes 33. C rings 44 and 45 are fixed at outer sides of the left and right wings 31 and clamp the post 43.
  • The positioning unit 6 is located between the right and left wings 3 1 for positioning the inner tube 2. The positioning unit 6 is formed with an axial hole 60. A front upper end of the positioning unit 6 is formed with a buckle bar 62. A rear end of the positioning unit 6 is installed with a driving arm 61. A cam portion 63 is formed at the front lower side of the positioning unit 6 and is in front of the axial hole 60. A stopper 65 extends from the driving arm 61. The post 43 passes through the axial hole 60 of the positioning unit 6. Thereby the positioning unit 6 is installed between the left and right wings 31 of the frame seat 3 and thus is rotatable along the post 43.
  • A spring 7 has one end buckled to the round hole 34 of one wing 31 and another end fixed to a cap 8. The cap 8 is screwed to a screw hole 64 at a rear lower end of the positioning unit 6. Thereby the assembly of the inner 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 the long hole 11 and then inserts into one of the positioning holes 20 of the inner tube 2 so that the inner tube 2 is fixed to a predetermined height. If it is desired to adjust the height of the inner tube 2, namely the height of the cushion 9, the driving arm 61 of the positioning unit 6 is moved. Then the positioning unit 6 will rotate along the post 43 so that the buckle 62 separates from the buckled positioning hole 20. Thereby the height of the inner tube 2 is adjustable (referring to FIG. 3). When the inner tube 2 is adjusted to a predetermined height, the positioning unit 6 is driven along an opposite direction so that the buckle bar 62 is further buckled to another positioning hole 20 of the inner tube 2 (referring to FIG. 4). It is known that when the user sits on the cushion 9 for exercise, the inner tube 2 suffers from a downward pressure. Since the positioning unit 6 has the cam portion 63, when the buckle bar 62 suffers from the gravitational force of the inner tube 2, the positioning unit 6 will swing along the post 43. Then the cam portion 63 will tightly resist against the wall of the inner tube 2, as shown in FIG. 5. Simply, by the pressure from the cam portion 63 of the positioning unit 6, the relative motion between the inner tube 2 and outer tube 1 will be greatly reduced so as to retain in a steady state. In the present invention, to avoid the cam portion 63 not to position the inner tube 2 due to wearing of the cam portion so that the inner tube 2 moves downwards, the stopper 65 can be stopped by the sleeve 42. Thereby the positioning unit 6 can not rotate unlimitedly along a direction illustrated in FIG. 5 and the buckle bar 62 do not separate from the positioning hole 20 so as to be retained in a steady state.
  • Thereby in the present invention, by the buckle bar 62 to buckle the positioning hole 20 of the inner tube 2, the inner tube 2 and outer tube 1 will not move relatively so as to have a preferred stability. Furthermore, in the present invention, the cam portion 63 of the positioning unit 6 tightly resists against the wall of the inner 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.
