Brief Patent Description - Full Patent Description - Patent Application Claims
BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a compound bicycle exercising device, and more particularly to a compound bicycle exercising device having handle devices arranged for being comfortably operated by users. [0003] 2. Description of the Prior Art [0004] Typical compound bicycle exercising devices comprise a transmission box driven by foot pedals, and a handle pivotally coupled to the transmission box, for allowing the handle to be rotated inwardly and outwardly, and for allowing users to conduct pedal driving or cycling exercises and hand operating exercises simultaneously. [0005] For example, U.S. Pat. No. 4,660,826 to Lee discloses one of the typical compound bicycle exercising devices which also comprises a pair of foot pedals provided to be rotated or driven by the users, and a pair of handles coupled to the foot pedals or the like, for allowing the handles to be pulled or driven or actuated by the users while operating the typical compound bicycle exercising devices. [0006] However, the two handles are solidly secured or coupled together, and the hand grip portions provided on top of the handles are solidly formed or bent or extended laterally from the handles, such that the hand grip portions of the handles may not be easily operated by the users, particularly when the hand grip portions of the handles are pulled toward the users. [0007] For example, when the hands of the users are moved forwardly and rearwardly relative to the users, it will be more uncomfortable for the hands of the users to move outwardly or away from each other when the hands are moved away from the users, and for the hands of the users to moved inwardly or toward each other when the hands are moved closer to the users, in order to suitably operate the compound bicycle exercising devices. [0008] The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional compound bicycle exercising devices. SUMMARY OF THE INVENTION [0009] The primary objective of the present invention is to provide a compound bicycle exercising device including one or more handle devices having rotatable handgrips arranged for being comfortably operated by users. [0010] In accordance with one aspect of the invention, there is provided a compound bicycle exercising device comprising a base, a pair of foot pedals rotatably attached to the base with a spindle and cranks, for being operated by users, a pair of handle stems each having a lower portion pivotally attached to the base with an axle, for being pulled and pushed and operated by the users, the handle stems each including an upper portion, and a pair of handgrips rotatably attached to the upper portions of the handle stems respectively, and rotatable inwardly and outwardly relative to the handle stems, to allow the handle stems to be easily pulled toward and away from the users by rotating the handgrips inwardly and outwardly relative to the handle stems. [0011] The handle stems each includes a casing provided on the upper portions thereof, and the handgrips each includes a shaft extended therefrom, and rotatably attached to the casing, to allow the handle stems to be rotatably attached to the casing with the shafts. The handgrips are each extended from a bracket, and the bracket includes the shaft extended therefrom and rotatably attached to the casing. [0012] The casing includes a bore formed therein, and a peripheral flange extended inwardly from one end of the casing and extended into the bore thereof, to form an aperture therein, and to rotatably receive the shaft. The casing includes at least one bearing disposed in the bore thereof, and engaged with the shaft, to rotatably attach the shaft to the casing. The shaft includes a retaining ring attached thereto, and engaged with the bearing, to rotatably attach the shaft to the casing, and to prevent the shaft from being disengaged from the casing. [0013] Further objectives and advantages of the present invention will become apparent from a careful reading of the detailed description provided hereinbelow, with appropriate reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS [0014] FIG. 1 is a perspective view of a compound bicycle exercising device in accordance with the present invention; [0015] FIG. 2 is a partial exploded view of the compound bicycle exercising device; [0016] FIG. 3 is an enlarged partial perspective view of a handle of the compound bicycle exercising device; [0017] FIG. 4 is a partial cross sectional view of the compound bicycle exercising device taken along lines 4-4 of FIG. 3; and [0018] FIG. 5 is a partial exploded view similar to FIG. 2, illustrating the operation of the compound bicycle exercising device. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT [0019] Referring to the drawings, and initially to FIGS. 1-4, a compound bicycle exercising device 10 in accordance with the present invention comprises a base 11 including a seat 12 optionally formed or provided thereon for supporting users, a pair of foot pedals 13 rotatably attached to the base 11 with a spindle 14 and cranks 15, for being driven or operated by the users, and a post 16 provided or extended from the front portion of the base 11 and having a control device or a control panel 17 provided on top thereof. [0020] The compound bicycle exercising device 10 further includes a pair of handle stems 20 each having a lower portion 21 rotatably or pivotally attached to the base 11 with an axle 22, for being pulled or pushed or operated by the users. The handle stems 20 each includes an upper portion 23 having a casing 24 disposed thereon. The casing 24 includes a bore 25 formed therein and preferably perpendicular to the handle stem 20, and a peripheral flange 26 extended inwardly, from one end, into the bore 25 thereof, to form an aperture 27 therein, best shown in FIG. 4.
