DETAILED DESCRIPTION OF THE INVENTION
[0015] Referring to FIGS. 1-6, a tie 10 according to the present
invention wraps around a plurality of cables 12, thereby bundling
the cables 12 together. Tie 10 is self-locking to secure the cables
12. A cushioning layer 14 (FIG. 4) of tie 10 grips the cables 12 to
restrict movement of the cables 12. Damage and shafting to the
cables 12 caused by contact with the tie is significantly reduced
by the cushioning layer 14.
[0016] In general, tie 10 includes a strap 16 with a strap body 18,
a fastening end portion 20, an opposite free end portion 22, and
first and second opposite surfaces 24 and 26. Strap 16 is
preferably made of a strong but flexible material, such as plastic,
nylon, polyetheretherketone, and the like. The strap body 18,
fastening end portion 20, and free end portion 22 are preferably
made as one-piece, but can be made separately and attached
together.
[0017] The fastening end portion 20 includes a fastener head 28
with a passageway 30 for receiving the strap body 18, as seen in
FIG. 4. Fastener head 28 has front and back ends 31 and 32 and
first and second sidewalls 34 and 36 extending therebetween.
Transverse to sidewalls 34 and 36 of head 28 are front and back
bridges 38 and 40 that define a first aperture 42, as seen in FIG.
2. A flexible locking pawl 44 extends into first aperture 42 from
the front bridge 38 toward the back bridge 40. Locking pawl 44
includes a plurality of engaging members 46 (FIGS. 3 and 4) for
retaining the strap body 18.
[0018] Opposite the first aperture 42 of the fastener head 28 is a
second aperture 48, as seen in FIGS. 3, 5 and 6. The passageway 30
for the strap 16 is located between the first and second apertures
42 and 48, which are continuous with the passageway 30. First and
second projections 50 and 52 extend into the second aperture 48
from the inside surfaces of the first and second sidewalls 34 and
36, respectively, for guiding the strap body 18. The free end
portion 22 of the strap 16 enters the passageway 30 through the
second aperture 48 and extends over the projections 50 and 52, as
seen in FIG. 3. A third aperture 54 is defined between the back
bridge 40 of the fastener head 28 and a terminal wall 56 of the
strap body 18, as seen in FIGS. 5 and 6. The free end portion 22 of
the strap 16 exits the passageway 30 through the third aperture 54,
as seen in FIGS. 1, 5 and 6.
[0019] Extending from the first surface 24 of the strap body 18 are
a plurality of engaging members 58 corresponding to the engaging
members 46 of the locking pawl 44 of the fastener head 28. Engaging
members 46 and 58 are preferably a plurality of teeth that
interlock with one another, as seen in FIG. 4. The engaging members
or teeth 58 of strap body 18 extend substantially continuously
along the first surface 24 of the strap 16 between the fastening
end portion 20 and the free end portion 22 of the strap 16.
Engaging members 46 and 58 can interlock in any known manner and do
not have to be teeth. For example, engaging members 46 and 58 can
frictionally engage each other, engage via a tongue and groove
arrangement, employ a snapping arrangement, or the like. Although a
plurality of engaging members or teeth 46 and 58 are preferred, a
single engaging member 46 and a single engaging member 58 can be
employed as long as the strap body 18 is locked in the passageway
30 by the members 46 and 58.
[0020] Cushioning layer 14 is disposed on the second surface 26 of
the strap 16. Cushioning layer 14 can be formed of any soft or
non-abrasive material, such as a polymer like silicone, ethylene,
propylene rubber, and the like. The cushioning layer 14 is
preferably molded onto the strap second surface 26 but can be
applied in any known manner such as adhesive and the like.
Cushioning layer 14 extends along second surface 26 substantially
continuously between the fastening end portion 20 and the free end
portion 22 of the strap 16. The soft polymer material of cushioning
layer 14 grips the cables 12 when the strap 16 is wrapped around
the cables 12. Alternatively, the cushioning layer 14 can be
discontinuous so that only portions of the second surface 26 of the
strap 16 are covered.
[0021] To bundle together the cables 12, the strap 16 of tie 10 is
wrapped around the cables 12 so that the strap first surface 24 is
an outer surface facing away from the cables 12 and the strap
second surface 26 is an inner surface so that the cushioning layer
14 engages the cables 12. Free end portion 22 of strap 16 is
inserted through the second aperture 48 of the fastener head 28
into the passageway 30. The strap body 18 extends through the
passageway 30 flexing the locking pawl 44 backward through the
first aperture 42, as seen in FIG. 5. More specifically, the front
surfaces 60 of the engaging teeth 58 of strap body 18 abut the back
surfaces 62 of the engaging teeth 46 of the locking pawl 44 to push
the locking pawl 44 outwardly, thereby allowing the strap 16 to
extend through the passageway 30 and exit through the third
aperture 54. The free end portion 22 of strap 16 can be pulled in a
first direction through the fastener head 28 to adjust the tie 10
to the number of cables 12 being bundled.
[0022] Once the strap 16 is adjusted and tightened around the
cables 12, the locking pawl 44 of the fastener head 28 flexes back
to its original position with its engaging teeth 46 interlocking
with the engaging teeth 58 of the strap body 18, as seen in FIG. 6.
The strap 16 is substantially prevented from being withdrawn from
the fastener head passageway 28 in a second direction opposite the
first direction through the second or entry aperture 48 by the
engaging teeth 46 and 58. More specifically, as seen in FIG. 6, the
back surfaces 64 of the teeth 58 of the strap 16 abut the front
surfaces 66 of the teeth 46 of the locking pawl 44 of the fastener
head 28 when the strap body 18 is pulled in the second direction,
thus restricting the strap body 18 from being pulled back through
the entry aperture 48. That ensures that the strap body 18 remains
locked within the fastener head passageway 30. To release tie 10
from the bundle of cables 12, the strap 16 is cut.
[0023] The cushioning layer 14 contacts and grips the cables 12
when the strap 16 is wrapped around the cables 12. This
substantially restricts the movement of the tie 10 with respect to
the cables 12, thereby significantly reducing damage to the cables
12 from the tie 10.
[0024] While a particular embodiment has been chosen to illustrate
the invention, it will be understood by those skilled in the art
that various changes and modification can be made therein without
departing from the scope of the invention as defined in the
appended claims. For example, the tie 10 can be used to bundle any
type of objects and not just cables 12. Also, structure can be
added to the locking pawl 44 of the fastening head 28 to facilitate
moving the locking pawl 44 outwardly to release the strap 16
disposed in the passageway 30.
