Description
BACKGROUND OF THE INVENTION
This invention relates generally to heated clothing, and more
particularly concerns a heated suit system which is modular and
which enables selective wearing of certain sections of the suit
without impairment of the heating function.
There is a need for heated garments in many sports and other
activities, such as for example, motorcycling, snowmobile operation
and the operation of construction equipment out of doors in cold
climates. On the other hand, a complete heated suit may become
locally uncomfortable to the wearer, to the extent that he requires
heating of only a selected portion of a complete suit. To my
knowledge, no prior heated clothing system embodies the unusual
advantages in structure, function and result such as one found in
the present system, and which overcome the above as well as other
problems associated with prior equipment.
SUMMARY OF THE INVENTION
It is a major object of the invention to provide a heated suit
system overcoming the above problems and incorporating numerous
unusual advantages as will appear. Basically, the clothing
comprises multiple sections each adapted to cover a different
portion of the human body; electrical wires carried by the sections
and including interconnected bus and heater wires; separable
electrical connections between the bus wires of adjacent clothing
sections; and, input electrical connections to the bus wires of at
least one of the clothing sections. As will appear that one section
may cover the wearer's waist and may be associated with a jacket
and/or trouser section; electrical input leads may be connected
with the input electrical connections which are releasable, and a
current control may be connected with at least one of the input
leads for suit temperature control, considering that greater
current or power will be required the more suit sections are
employed; the suit sections are typically separately fastened
together, as will be seen, and they may include glove, hood, face
mask and slipper sections as well as jacket and trouser
sections.
These and other objects and advantages of the invention as well as
the details of an illustrative embodiment will be more fully
understood from the following description and drawings, in
which:
DRAWING DESCRIPTION
FIG. 1 is a side elevation showing a motorcyclist whose suit
embodies the invention;
FIG. 2 is a showing of the FIG. 1 suit, with same wiring details
illustrated;
FIG. 3 is an enlarged section on line 3--3 of FIG. 2;
FIG. 4 is an enlarged fragmentary section, partly broken away, on
line 4--4 of FIG. 2;
FIG. 5 is an enlarged cross-section on line 5--5 of FIG. 4; and
FIG. 6 is a wiring diagram.
DETAILED DESCRIPTION
In the drawings, the suit 10 comprises multiple clothing sections
each adapted to cover a different portion of the human body. For
example, the suit 10 includes a jacket 11 to the arms 11a of which
gloves 12 are attached as by snap fasteners 13, and to the neck 11b
of which a hood 14 is attached as by snap fasteners 15. Also, a
face mask 16 is attached to the hood as by snap fasteners 17. The
suit also includes trousers 18 having snap fastener attachment to
the jacket at 19; and slippers 20 having snap fastener attachment
to the trouser legs 18a at 21. The latter are shown in detail in
FIG. 3, although other forms of fasteners may be employed.
Electrical wires are carried by each clothing section, and include
bus wires and heater wires connected therewith (as for example
between the bus wires). This is tabulated as follows, with added
reference to FIG. 6:
Clothing Section Bus Wires Heater Wires
______________________________________ jacket 11 21,22 23 gloves 12
24,25 26 hood 14 27,28 29 face mask 16 30,31 32 trousers 18 33,34
35 slippers 20 36,37 38 ______________________________________
In addition, separable electrical connections are established
between the bus wires of adjacent clothing sections, as tabulated
as follows:
Adjacent bus wires Separable connectors
______________________________________ 22 & 24 39 21 & 25
40 21 & 27 41 22 & 28 42 27 & 30 43 28 & 31 44 33
& 36 45 34 & 37 46
______________________________________
Further, input electrical connections are established to the bus
wires of at least one of the clothing sections, and in the drawings
such input connections are established at 47 and 48 between input
leads 49 and 50 and jacket buses 21 and 22, respectively; and in
addition are also established at 51 and 52 between input leads 49
and 50 and trouser buses 33 and 34, respectively. All of the
connectors are of the releasable plug-in type, as indicated in the
drawings, so that, for example, if connections 51 and 52 are
released, the trousers and slippers will not be heated; and if
connections 47 and 48 are released, the jacket and the gloves, face
mask and hood will not be heated. It is also seen that various of
the connections 39 and 40, 41 and 42, 43 and 44, and 45 and 46 may
be unplugged to prevent heating of the associated clothing
elements.
A current control is provided as at 60 in series with input leads
49 and 50 to control the power or current supplied to the suit so
as to vary the heating as required by the number of clothing
sections remaining electrically connected with the input leads, as
described. An AC or DC power source is indicated at 61, and may for
example comprise a battery on the motorcycle. Merely as
illustrative, a fully operating suit will draw between 1 to 1.5
amperes at about 12 volts.
The wires (bus and heater or resistance) may be embedded between
clothing layers, as indicated in FIGS. 4 and 5 where bus wire 33
extends between trouser leg layers 18a' and 18a". Note that
insulation 64 may surround the bus wire, and this construction may
also be employed throughout. The clothing may comprise a liner for
outer clothing, or it may comprise the main garment, with an
insulative outer layer as at 65 in FIG. 4.
The plug-in type connectors may include plugs and receptacles, with
snap or screw-in retention. One commercial type connector is a
product of E.F. Johnson Company, and bears jack and plug numbers
108-0902-001, 108-0903-001, 108-0302-001, and 108-0302-001.
From the above, it is clear that the invention provides very simple
and advantageous selectively wearable clothing sections which are
selectively heated in response to electrical interconnection of the
clothing sections.
