Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to timing and pacing devices and
more particularly to a novel electronic pacer timer intended to be
worn about a portion of an individual's body and which is settable
to provide pace signals for the pacing of an individual's body
movement in jogging, walking and the like.
2. Description of the Prior Art
In many sports and activities it is desired that an individual pace
or time himself for the smoothest body movement providing maximum
durability and most efficient use of the body. A problem associated
with conventional pacer-timer apparatus available in the prior art
is that they are usually too large to be conveniently carried by an
individual during the pacing operation of running, jogging, walking
and the like, or if conveniently carried they require substantially
constant visibility to the individual to achieve the desired pacing
effect, such as the use of a stop watch which requires that the
individual constantly watch and time the same in conjunction with
the body movements to obtain the desired pacing affect.
SUMMARY OF THE INVENTION
The present invention recognizes the problem of an individual
wishing to pace their body movements without having to maintain
constant visible vigilence of the pacing apparatus, such as a stop
watch and the like, with the present invention providing a novel
solution thereto consisting of a compact electronic pacer timing
device readily worn about a portion of an individual's body and
which provides an audible output of a frequency settable by the
individual to obtain a pacing signal for the individual to use in
pace setting of the individual's body movements.
It is a feature of the present invention to provide a lightweight,
compact and efficient pacer-timer adapted to be worn by an
individual and to provide audible pacing signals for use by the
individual in pacing their body movements.
Still a further feature of the present invention provides a
pacer-timer which is relatively inexpensive to manufacture due to
its simplicity of construction; one which is possessed of few parts
and which therefore is unlikely to get out of order; one requiring
a minimum of maintenance and supervision; one which is rugged and
durable in construction and which therefore may be guaranteed by
the manufacturer to withstand many years of intended usage; one
which is easy to use and reliable and efficient in operation; one
which is readily adjustable by the individual while in use in a
manner to change the pace at any desired time without requiring
visible vigilence to make such changes; and one which is well
adapted to perform the services required of it are among the
desirable features and advantages of the present invention.
Other features and advantages of this invention will be apparent
during the course of the following description.

In the accompanying drawings forming a part of this specification,
and in which like reference characters are employed to designate
like parts throughout the same:
FIG. 1 is a perspective view of an individual wearing the
pacer-timer device of the present invention;
FIG. 2 is a perspective view of the pacer-timer device; and
FIG. 3 is an electrical schematic diagram of the circuit of the

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to the drawings in detail there is illustrated a
preferred form of a pacer-timer device constructed in accordance
with the principles of the present invention and designated
generally in its entirety by the reference numeral 10. The
pacer-timer device 10 includes a hollow box-like housing 11 having
a top surface 12, a bottom surface 13, a front surface 14, a back
surface 15, and opposed side surfaces 16 and 17. A substantially
flat circular disc 18 is mounted in the housing 11 for rotation
about its axis and is provided with a knurled circumferal edge 19,
a portion of the disc projecting through a slot 20 in side wall 17
in a manner to be engaged by an individual's finger in a manner to
effect the rotation of the disc about its axis. The face surface of
the disc 18 adjacent the interior surface of front wall 14 is
provided with a plurality of indicating numerals 21 disposed
sequentially about the circumference thereof and adapted to be
selectively brought into orientation with a rectangular opening 22
provided in housing face surface 14, such indicating numerals
designating positions of the disc 18 for reference by the
individual in selecting a desired pacer output from the pacer-timer
device 10 as will be later described. An electrical earphone jack
23 is mounted in housing top surface 12 and is adapted to receive
the plug end of an electrical wire 24 having an earphone 25 mounted
at the opposite end thereof and adapted to be worn in the ear of an
individual 26 when using the pacer-timer device 10.
While it is to be understood that the pacer-timer device may be
worn about any portion of the body of the individual 26, such as
about the waist as shown, it is accordingly provided with a
flexible strap 28 mounted to housing 11 and projecting from
opposite side walls 16 and 17 and having associated therewith
required suitable fasteners, such as buckles and the like, for
retaining the device to the individual's body.
Referring now to FIG. 3 it is seen that the device comprises a
battery 40 which may be of the nine to twelve volt variety; three
bipolar junction transistors 41, 42 and 43, four diodes 44, 45, 46
and 47; three capacitors 48, 49 and 50; three resistors 51, 52 and
53; two interconnected variable adjustable resistors 54 and 55, and
the coil 56 of the earphone 25. The transistors 41 and 42 are of
the NPN type with the transistor 43 being of the PNP type.
In the preferred embodiment, resistor 51 is 1,200 ohms, resistor 52
is 1,500 ohms, resistor 53 is 8,200 ohms, resistors R3 and R4 are
coupled together for adjustability to disc 18 with each of these
resistors being adjustable between 33,000 ohms to 50,000 ohms,
capacitor 48 is 15 microfarads, capacitor 49 is 15 microfarads, and
capacitor 50 is 1 microfarad.
Resistor 51 has one end connected to the positive terminal of
battery 40, the opposite end being connected to the base of diode
44 and to one end of capacitor 48 and to the collector of
transistor 41. The emitter of transistor 41 is connected to the
base of diode 46 with the opposite end of the diode connected to
the negative terminal of battery 40. The resistor 52 has one end
connected to the positive terminal of battery 40, the opposite end
connected to the base of diode 45 and one end of capacitor 49 and
to the collector of transistor 42. The emitter of transistor 42 is
connected to the base of diode 47 with the opposite end of diode 47
being connected to the negative terminal of battery 40. The
opposite ends of diodes 44 and 45 are connected together. One end
of variable resistor 54 is connected to the junction between diodes
44 and 45, the opposite end of resistor 54 connected to the
opposite end of capacitor 48 and also to the base of transistor 42.
Similarly, one end of variable resistor 55 is connected to the
junction between diodes 44 and 45 with the opposite end connected
to the opposide end of capacitor 49 and to the base of transistor
41. The transistor 43 has its emitter connected to the negative
terminal of battery 40 with its collector connected to one end of
earphone coil 56, the opposite end of the earphone coil being
connected to the positive terminal of the battery 40. The base of
transistor 43 is connected through capacitor 50 to the collector of
transistor 42. The resistor 43 has one end connected to the
positive terminal of battery 40 with the opposite end connected to
the base of transistor 43 and serves as a bias resistor.
The transistors 41 and 42 and circuitry associated therewith define
a multi-vibrator circuit having energy pulse output ranging from
between 0.4 to 3 seconds with the resistors 54 and 55 connected in
the circuit to adjust the pulse timing thereof to any selected
timing within the aforementioned range. The output of the
multi-vibrator circuit is coupled through capacitor 50 to
transistor 43 where it is amplified to generate pulses through
earphone coil 56 resulting in audible pulsating sounds at earphone
25.
An individual wearing the pacer-timer device 10 may thus select the
desired pulse output as to the frequency of the same, or in other
words, as to the duration of time between pulses purred in earphone
25, the individual using the same to pace his respective body
movements for jogging, walking, running and the like.
It is to be understood that the form of this invention herewith
shown and described is to be taken as a preferred example of the
same, and that this invention is not to be limited to the exact
arrangement of parts shown in the accompanying drawings or
described in this specification as various changes in the details
of construction as to shape, size, and arrangement of component
parts may be resorted to without departing from the spirit of the
invention, the scope of the novel concepts thereof, or the scope of
the sub-joined claims.
