Speed control rocker arm for an electric treadmill
Abstract
The present invention relates to a speed control rocker arm for
an electric treadmill, The electric treadmill stated by the present
invention includes an upright frame, a base frame, a front
supporting leg and a rear supporting leg. A console is mounted on
the upright frame, and a handrail is fitted to either side thereof.
A motor-driven assembly is fitted to the base frame so that a
continuous belt circles therearound for an in-place rotation. In
addition, two rocker arms can be held by both hands of a user for a
forward and backward swinging movement. The console fitted to a
handgrip of the rocker arms contains a plurality of control keys
like speed control or slope adjusting keys so that the operator can

Claims
What is claimed is:
1. A speed control rocker arm for an electric treadmill comprising
an upright frame, a base frame, a front supporting leg and a rear
supporting leg, a console being mounted on said upright frame, a
handrail being fitted to either side thereof, a motor-driven
assembly being fitted to said base frame so that a continuous belt
circles therearound for an in-place rotation, two rocker arms being

recited in claim 1, wherein said control keys are fitted to a
handgrip of said rocker arms, respectively, and wherein said
control keys on one of said rocker arms is used for the increasing
adjustment of the speed and the slope while said control keys on
the other rocker arm is used for the decreasing adjustment of the
speed and the slope.
3. A speed control rocker arm for an electric treadmill comprising
an upright frame, a base frame, a front supporting leg and a rear
supporting leg, a console being mounted on said upright frame, a
handrail being fitted to either side thereof, a motor-driven
assembly being fitted to said base frame so that a continuous belt
circles therearound for an in-place rotation, two rocker arms being
provided and held by both hands of a user for a forward and
backward swinging movement; wherein the improvement is
characterized by: a physiological detector in connection with the
console being fitted to said handgrip of said rocker arms.
Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a speed control rocker arm
for an electric treadmill, and more particularly, to a device which
is practical and convenient.
[0003] 2. Description of the Prior Art
[0004] Many commercially available electric treadmills 10 are
provided with two rocker arms 20 swingable backward and forward
along with both arms of the operator and fitted to an upright frame
12 (see FIG. 1), a base frame 14 (see FIG. 2) or an handrail 16
(see FIG. 3). Even, a resistant element (not shown) is added to the
rocker arms 20 so that the operator can train the arm muscle while
walking. These disclosures can be seen in U.S. Pat. Nos. 5,460,586,
5,527,245, 5,688,209, 5,431,612, 5,207,622, 5,860,894, 5,709,632,
etc.
[0005] The rocker arms 20 have no design drawbacks concerning the
basic function of swinging both hands of the operator. However, in
order to adjust the walking speed or the supporting slope of the
base frame 14 while walking, he has to stop using the rocker arms
20 or walking and goes toward the console 18 to press the
corresponding control keys (not shown). After the adjustment, he
returns to the exercise position for holding the rocker arms 20 to
continue the exercise session, thereby causing much inconvenience
in using.
SUMMARY OF THE INVENTION
[0006] It is a primary object of the present invention to remove
the above-mentioned drawbacks and to provide a speed control rocker
arm for an electric treadmill on which a plurality of control keys
in connection with a console is provided for adjusting the walking
speed and the slope of the base frame.
BRIEF DESCRIPTION OF THE DRAWINGS
[0007] The accomplishment of this and other objects of the
invention will become apparent from the following description and
its accompanying drawings of which:
[0008] FIG. 1 is a schematic drawing of the present invention which
is fitted to both sides of the upright frame of an electric
treadmill;
[0009] FIG. 2 is a schematic drawing of the present invention which
is fitted to both sides of the base frame of the electric
treadmill; and
[0010] FIG. 3 is a schematic drawing of the present invention which
is fitted to both sides of the handrail of the electric
treadmill.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0011] First of all, referring to FIGS. 1, 2 and 3, the electric
treadmill stated by the present invention includes an upright frame
12, a base frame 14, a front supporting leg 11 and a rear
supporting leg 13. A console 18 is mounted on the upright frame 12,
and a handrail 16 is fitted to either side thereof. A motor-driven
assembly (not shown) is fitted to the base frame 14 so that a
continuous belt (not shown) circles therearound for an in-place
rotation. In addition, two rocker arms 20 can be held by both hands
of a user for a forward and backward swinging movement.
[0012] The console 18 fitted to a handgrip 21 of the rocker arms 20
contains a plurality of control keys 22 like speed control or slope
adjusting keys so that the operator can adjust the speed of the
treadmill and slope while walking.
[0013] The slope adjustment means the basic functions performed by
the electrically elevating mechanism for the walking platform. This
mechanism has been widely applied to each of electrical treadmills.
Thus, no further descriptions are given hereinafter.
[0014] The control keys 22 are fitted to the handgrip 21 of the
rocker arms 20, respectively. The control keys 22 on one of the
rocker arms 20 can be used for the increasing adjustment of the
speed and the slope while the control keys 22 on the other rocker
arm 20 can be used for the decreasing adjustment of the speed and
the slope.
[0015] Besides, a physiological detector (not shown) in connection
with the console 18 can be fitted to the handgrip 21 of the rocker
arms 20 in order to measure a few physiological parameters (like
pulse, etc.) to transmit back to the console 18 so that the console
18 can automatically optimize an exercise program in accordance
with the individual physical state.
[0016] Many changes and modifications in the above-described
embodiments of the invention can, of course, be carried out without
departing from the scope thereof. Accordingly, to promote the
progress in science and the useful arts, the invention is disclosed
and is intended to be limited only by the scope of the appended
claims.
