Description
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.

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.
[0021] A bracket 30 includes a shaft 31 extended therefrom, and
rotatably engaged into the bore 25 of the casing 24 via the
aperture 27 of the casing 24 (FIG. 4), and rotatably secured to the
casing 24 with one or more bearings 32 that are engaged in the
casing 24, for allowing the bracket 30 to be smoothly rotated
relative to the casing 24 and thus the handle stem 20. A retaining
ring 33 may further be secured onto the shaft 31 and engaged with
the casing 24 or the bearings 32, for rotatably securing the shaft
31 of the bracket 30 to the casing 24.
[0022] The shaft 31 of the bracket 30 may be solidly extended from
the bracket 30 by such as molding or mold injection processes, or
may be secured to the bracket 30 by such as fasteners, latches (not
shown), or the like. The bracket 30 further includes a handgrip 34
extended therefrom, and preferably perpendicular to the shaft 31.
The handgrip 34 is formed integral or solidly secured to the
bracket 30, to allow the handgrip 34 and the bracket 30 to be
rotated in concert relative to the casing 24.
[0023] The handgrip 34 and the bracket 30 may also be secured or
formed integral with each other into a one-integral-piece
structure, and having the shaft 31 extended from the handgrip 34 or
the bracket 30, to allow the handgrip 34 to be directly and
rotatably secured to the casing 24 or to the handle stem 20 with
the shaft 31, and thus to allow the handgrips 34 to be rotated
inwardly and outwardly relative to the casing 24 and the handle
stem 20 (FIGS. 2, 5).
[0024] It is preferable that the bracket 30 further includes one or
more switch buttons 35 provided thereon, for being depressed or
actuated by the users, for such as adjusting resistive forces
applied to the foot pedals 13 and/or for adjusting resistive forces
applied to the handle stems 20.
[0025] In operation, as shown in FIGS. 2 and 5, the handgrips 34
may be rotated inwardly and outwardly relative to the casing 24 and
the handle stem 20, particularly when handgrips 34 are pulled
toward and away from the seat 12, such that the handle stem 20 may
be easily operated or pulled toward and away from the seat 12 by
the users.
[0026] Accordingly, the compound bicycle exercising device in
accordance with the present invention includes one or more handle
devices arranged for being comfortably actuated or operated by
users.
[0027] Although this invention has been described with a certain
degree of particularity, it is to be understood that the present
disclosure has been made by way 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 claimed.
