Description
TECHNICAL FIELD
[0001] This invention relates generally to wiring harnesses, and
more particularly, to the attaching of a wiring harness to a fixed
support.
BACKGROUND
[0002] Wires and wiring harnesses are used in all types of
electrical devices, and have been used in great abundance in a
variety of machines, such as automobiles, construction and
earthmoving equipment, and other utility vehicles. Often the wiring
harnesses are mounted in cramped spaces that are difficult to
access such as within the dashboard, firewall, or other fixed
support.
[0003] In the past, many wiring harnesses are attached to the fixed
support with some type of clip. The clip is typically affixed to
the fixed support, and the wiring harness is slipped into the
clip.
[0004] One problem with this configuration is that the person
installing the wiring harness often has a partially or totally
obstructed view of the locations of the clips. Thus, the installer
is forced to feel around for the locations of the clips in order to
install the wiring harness. Further, many clips only accept the
wiring harness from a particular angle, e.g., straight on. Thus,
the harness must have a clear path along that angle, which can be
problematic in tight quarters.
SUMMARY OF THE INVENTION
[0005] The present invention provides apparatus and methods for
attaching a wire with a work machine. At least one mat of one of
hook type and a loop type material covers a substantial portion of
a predetermined wire pathway on a work machine. At least one strip
of the other of the hook type and the loop type material wraps
respective portions of the wire and mates with the one of the hook
type and the loop type material of one of the mats.

[0009] FIG. 4 shows another way to attach the wire to the mat

DETAILED DESCRIPTION
[0010] FIG. 1 is a head-on view of an apparatus 10 for attaching a
wire 12 or other flexible chord to a rigid support, such as a
dashboard, body panel, or firewall 14, of a work machine (not
shown) according to one embodiment of the invention. Although only
a single wire 12 is shown, the invention is equally applicable to
multiple wires, wiring harnesses, or any other type of flexible
chord. The work machine may be any of a variety of machines known
to those skilled in the art, such as by way of example and not
limitation, automobiles, trucks, construction and earthmoving
equipment, golf carts, snowmobiles, boats, all-terrain vehicles,
and other utility vehicles.
[0011] The apparatus 10 includes a mat 16 of a hook and loop type
material, such as Velcro.RTM.. The mat 16 typically is a single
type, i.e., either the hook type material or the loop type
material, although it could also have portions of each. The mat 16
may be fixed to, e.g., adhered, to the firewall 14 by any of a
variety of appropriate ways known to those skilled in the art. The
mat 16 is typically a flexible material, able to conform to the
contours, if any, of the firewall 14, although it need not be.
[0012] The mat 16 typically covers a pathway of the wire 12. The
pathway may be considered to be the possible, likely, and/or
desired paths of the wire 12. The pathway may be only a portion of
the length of the wire 12, or it may be the entire length.
[0013] The pathway is typically a function of the desired location
of the wire 12 and the available surface portions, e.g., attachment
locations, of the firewall 14. For example, it may be desirable to
run the wire 12 along the firewall 14 under a dash (not shown) of
the work machine. Thus, in this example, because the dash is
located near the top portion of the firewall, the pathway is
located in that area. The pathway detours around, or is not present
in, areas in which it is desired that the wire 12 not pass through
or need not pass through. For example, the pathway would typically
not be in an area where a cutout 18 in the firewall 14 for a
steering wheel column is (not shown), or in an area for a
false-pedal or footrest 20, and in areas where other items or
devices are to be, such as pedals 22. The mat 16 may then be shaped
appropriately to cover the defined or predetermined pathway for the
wire 12. The pathway is typically substantially wider than the
width, i.e., diameter, of the wire 12, although it need not be.
[0014] Although the mat 16 is depicted in FIG. 1 as being a single
piece, in other embodiments of the invention the mat 16 may be
multiple pieces (not shown): in effect, multiple mats. The multiple
pieces may be placed so as to have relatively insignificant gaps
(from a functional perspective) between them or they may directly
abut or overlap each other.
[0015] In one embodiment of the invention, the mat 16 covers a
substantial portion of the pathway. In another embodiment of the
invention, the mat 16 covers as little as 50% of the length of the
pathway, having at least one gap, and more typically several gaps
along the length of the pathway, such as between pieces of the mat
16. These gaps are typically of a size and have a spacing between
them so as to still provide sufficient attachment points for a
strip 24 or plurality of strips 24 as discussed below.
[0016] The strip 24 of the other type of the hook type and the loop
type material, i.e., capable of mating with the mat 16, may be
wrapped around or coupled with the wire 12 by any of a variety of
ways known to those skilled in the art. The strips 24 mate with,
e.g., adhere to, the mat 16 by ways known to those skilled in the
art, thereby affixing the wire 12 with the firewall 14.
[0017] The strip 24 may encircle the wire 12 according to one
embodiment of the invention, as shown in FIG. 2, or it may spiral
around the wire 12 according to another embodiment of the
invention, as shown in FIG. 3. The width of the strips 24 may be
such so as to cover the entire wire 12, or only some small portion
thereof. Although the strips 24 are depicted in the Figures as
being generally rectangular, in other embodiments of the invention
the strips 24 may be any of a variety of shapes known to those
skilled in the art. The strips 24 are typically placed at
appropriate locations known to those skilled in the art along the
wire 12.
[0018] FIG. 4 shows another way to attach the wire 12 to the mat 16
according to one embodiment of the invention. The strip 24 is
affixed to a platform 26 by any of a variety of ways known to those
skilled in the art. In one embodiment of the invention, the
platform 26 may be a substantially rigid, although it need not be.
A cable tie 28 or other suitable attaching device known to those
skilled in the art is also affixed to the platform 26. The cable
tie 28 encircles a portion of the wire 12, coupling the wire 12
with the platform 26 and the strip 24.
[0019] As many or as few strips 24 may be used as is appropriate.
For work machines operating in or producing a high vibration
environment, or for wires 12 that are heavy, more strips 24 would
typically be used. Low vibration environments and lighter wires 12
would typically require fewer strips 24.
Industrial Applicability
[0020] In operation, after the strips 24 are affixed to the wire
12, the strips 24 may be pressed against the mat 14 in
predetermined locations. However, because the strips 24 will
typically mate with any section of the mat 16, precise placement of
the strips is not necessary. Thus, obstructed views of the mat 14
do little to hinder installation of the wire 12. Similarly, because
of the nature of the hook and loop material, the strips 24 will
typically adhere to the mat 14 from any approach angle. Thus, the
strips 24 need not approach the mat head-on as is the case with
many conventional wire clips. This further simplifies the
installation procedure. Finally, because in some embodiments the
mat 16 covers a relatively large area (see FIG. 1), the mat 16
presents a relatively large "target" for the strips 24, as well as
increased options for the precise routing of the wire 12.
[0021] From the foregoing it will be appreciated that, although
specific embodiments of the invention have been described herein
for purposes of illustration, various modifications may be made
without deviating from the spirit or scope of the invention.
Accordingly, the invention is not limited except as by the appended
claims.
