Dumbbell with means to detect and show physical conditions of the
operator
Abstract
A dumbbell includes a dumbbell body and an instrument, the
instrument having a main unit fixedly mounted on the surface of the
dumbbell body and sensor means fixedly mounted on the dumbbell body
and electrically connected to the main unit, wherein the sensor
means detects the number of cycles within which the operator moves
the dumbbell body up and down as well as the heart beat of the
operator for enabling the main unit to calculate the amount of heat
energy consumed by the operator during exercising when the operator
presses the thumb on the sensor means.

Claims
What the invention claimed is:
1. A dumbbell comprising a dumbbell body, and an instrument fixedly
mounted on said dumbbell body, said instrument comprising a main
unit fixedly mounted on said dumbbell body, and sensor means
fixedly mounted on said dumbbell body and electrically connected to
said main unit for pressing by the operator's thumb and adapted to
detect the number of cycles within which the operator moves said
dumbbell body up and down as well as the heart beat of the operator
for enabling said main unit to calculate the amount of heat energy
consumed by the operator during exercising when the operator
operates the dumbbell and presses the thumb on said sensor
means.
2. The dumbbell of claim 1 wherein said main unit is fixedly
mounted on a handgrip of said dumbbell body, comprising a LED
display, a set of entry keys, and a control circuit board.
3. The dumbbell of claim 2 wherein said dumbbell body comprises a
first receiving chamber, which receives the main unit of said
instrument, and a second receiving chamber disposed in a handgrip
thereof, which receives said sensor means.
Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to exercising apparatus and,
more particularly, to a dumbbell, which has means to detect and
show the physical conditions of the operator.
[0002] A variety of physical exercising apparatus have been
developed and have appeared on the market. These physical
exercising apparatus include weight-training apparatus such as
dumbbells; compound weight lifting machines and etc. There are also
known physical exercising apparatus designed for physical endurance
training such as jogging machines, stationary bicycles, and etc.
Advanced exercising apparatus are seen in Utility models #87206847;
#87206288; #87211144. These advanced exercising apparatus are
commonly equipped with an instrument adapted to show a variety of
exercising data including the length of exercising time, the
exercising speed, the amount of load, and etc. There are also known
new designs of dumbbells. Exemplars of new designs of dumbbells are
seen in Utility models #85212272; #86309105; #84218848. However,
these new designs of dumbbells have no means to indicate the
operator's physical conditions.
SUMMARY OF THE INVENTION
[0003] The present invention has been accomplished under the
circumstances in view. It is the main object of the present
invention to provide a dumbbell, which has means to show the
physical conditions of the operator when operated by the operator,
so that the operator can determine when to stop exercising,
preventing the occurrence of a possible athletic injury. To achieve
this and other objects of the present invention, a dumbbell is
provided comprising a dumbbell body and an instrument, the
instrument comprising a main unit fixedly mounted on the surface of
the dumbbell body and sensor means fixedly mounted on the dumbbell
body and electrically connected to the main unit, wherein the
sensor means detects the number of cycles within which the operator
moves the dumbbell body up and down as well as the heart beat of
the operator for enabling the main unit to calculate the amount of
heat energy consumed by the operator during exercising when the
operator presses the thumb on the sensor means.
BRIEF DESCRIPTION OF THE DRAWINGS
[0004] FIG. 1 is a perspective view of a dumbbell constructed
according to the present invention.
[0005] FIG. 2 is a perspective view of an alternate form of the
dumbbell according to the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0006] Referring to FIGS. 1 and 2, a dumbbell 10 is shown
comprising a dumbbell body 12, and an instrument 14 installed in
the dumbbell body 12. The instrument 14 comprises a main unit 22,
and a sensor 24. The main unit 22 of the instrument 14 is fixedly
mounted in a first chamber 26 at one end of the dumbbell body 12,
comprising a LED display 28, a set of entry keys 30, a counter and
a control circuit board (not shown). The sensor 24 is fixedly
mounted in a second chamber 36 at the handgrip 34 of the dumbbell
body 12, and electrically connected to the main unit 22 by an
electric wire 32.
[0007] When in use, the operator inputs personal data of body
height and body weight through the entry keys 30 into the
instrument 14. When operating the dumbbell 10, the thumb is pressed
on the sensor 24, enabling the sensor 24 to detect with the counter
of the main unit 22 the number of cycles within which the dumbbell
10 is lifted and lowered as well as the heart beat of the operator.
The detected data is compared with the operator's personal data
been pre-set in the main unit 22, enabling the control circuit
board of the main unit 22 to calculate the amount of heat energy
(calories) consumed.
[0008] In short, the dumbbell 10 is used to exercise the arms, and
to indicate the operator's physical conditions when operated.
Because the operator knows one's physical conditions when
exercising, possible athletic injury is eliminated.
[0009] Further, the dumbbell body 12 of the dumbbell 10 can have
any of a variety of shapes. FIG. 2 shows an alternate form of the
dumbbell 10.
[0010] While only one embodiment of the present invention has been
shown and described, it will be understood that various
modifications and changes could be made thereunto without departing
from the spirit and scope of the invention disclosed.
