Background of the Invention
I. Field of the Invention
The present invention relates to devices for capturing items,
such as for handling or storage of electrical cords or cables or other
applications.
II. Description of Prior Art
Handling and/or storage of items has presented numerous
challenges, and despite various handling and storage devices that have been
devised, several problems continue to be difficult to resolve.
One example is the problem of storage of electrical cords or
cables. Many people tend to leave their cords simply in a pile. Such an
approach is both unsightly and can be unsafe. Indeed, without better
organization of the cords, storage can become a nightmare. One need only
consider the PC laptop user trying to untangle the mess of cables from the
briefcase in a busy airport.
Typically, wire-ties, tie wraps, cable ties, or twist-ties may be
used to store cords in an effort to reduce such problems. However, such items
are very difficult to use and require a great deal of manual dexterity. In
particular, closing these ties around the bundled cord is quite challenging
because the ends are free to go wherever they are pushed. Some of those
items, and particularly twist-ties such as are used to close garbage bags, are
unsightly, have only a short useful life, and can present a risk of injury due to
the metal wire contained therein. Other cable management devices have been
proposed, but they are usually quite bulky and again require a great deal of
manipulation. By way of example, some cable management devices are
molded into a split ring with the ends normally urged together. The ends may
be temporarily held apart by the user while a cable is inserted into the device.
Such a device is difficult to load with the bundled wire because the ends are
normally urged together into a closed or nearly-closed position.
When not attached to a cable or wire, a small wire tie or similar
device is easy to lose. Also, such devices are typically designed for limited
use, e.g., they cannot be non-destructively removed, or will experience
substantial wear (e.g., metal fatigue) if repeatedly opened and closed. Thus,
one cannot avoid losing a twist tie or wire tie by attaching it to the unbundled
cable, since doing so will require destruction or damage to the twist tie or wire
tie. This is a particular drawback in storage of cables which must be
repeatedly bundled and unbundled, e.g., extension cords used with hand tools,
portable computer cabling, and other similar applications.
Aside from bundles of wires, in various other situations,
objects must be wrapped and held for storage, handling or other reasons; often
wire ties, twist ties, or lengths of string are used in such situation, with
unsatisfactory results for the same reasons as those noted above: difficulty in
use, likelihood of loss, and destruction and wear resulting from repeated use.
Accordingly, there is a need for a device that can be readily
used in handling and/or storage of bundles of items which can be easily used,
has a reduced likelihood of being lost when not in use, and is not subject to
destruction and wear from repeated use.
Summary of the Invention
The present invention provides a device for handling and/or
storing items, which is easily used, less subject to loss, destruction and wear.
A device in accordance with the principles of the present invention, utilizes a
pair of rigid jaws which have a self-sustaining open position and are self-
aligned so as to readily close about the item being handled or stored. The
rigid jaws may be in the form of a handcuff-like element, or other hinged and
self-aligning arrangements. A "rigid" material, for the purposes of this
application, does not exclude some resilience, but only requires sufficient
rigidity that the ends of the jaw members will self- align when the device is
pressed to its closed position. Furthermore, a "rigid" material, for the
purposes of this application, may be deformable (which may occur as part of
inserting items between the jaws) so long as the material sufficiently returns to
its original shape that the ends of the jaw members will self-align.
In the specific embodiments described below, the device
includes engaging mechanisms at the outer ends of the jaws which interact to
hold the jaws closed in one of several possible positions. These mechanisms
may be barbed teeth and a pawl for engaging the teeth. The pawl may be
driven by spring force into its engaging position, and must be manually
pushed from its engaging position to disengage the outer ends of the jaws.
Alternatively, the pawl may be driven by spring force into its disengaging
position, in which case a mechanical latch is used to hold the pawl in place in
its engaged position; releasing this latch permits the spring force to disengage
the pawl. The teeth and the mating pawl may be formed on any opposed
surfaces of the jaw ends, e.g., the top, sides or bottoms thereof.
In further embodiments, an engaging mechanism in the hinge
axle may be utilized to hold the jaws in a closed position. The jaws may be
held together at their hinge ends by a hinge axle or a hinge strap. The device
may include a clip so that the device may be attached to the items with which
it is used so that the device is not readily lost. Alternatively, or in addition,
the device may include an attachment hole or hook so that the device can be
hung on a hook, nail or peg, or the owner can tie a string through the hole in
order to tie the device to the item with which it is used. The device may
include an integral or removable handle facilitating its used particularly in
handling heavy items. The device may also be constructed to include indicia
surfaces which can carry a product name or an advertisement.
The various embodiments of the device described herein are
readily used in various applications, without suffering from the above-
mentioned drawbacks of wire ties, twist ties and other known approaches.
Applications include storing or handling items such as bundled electrical cords
or cables, or other various items such as clothing (e.g., belts, ties, jewelry),
keyrings, fabrics (e.g., napkins), shopping bags or other collections of items
with handles or loops that can be bundled, plantings, or other numerous other
items. The device can also be used for child safety applications or as a
personal adornment.
These and other objects of the present invention shall be made
apparent from the accompanying drawings and description thereof.

Detailed Description of the Drawings
With reference to Figs. 1 and 2, there is shown a handcuff-like
element 10 which may be used to handle or store an elongated item such as
electrical cord or cable 12 (Fig. 3 A) which may have connectors or plug
elements 13 at opposite ends thereof, and which has been bundled together
(Figs. 3C and 3D). To this end, handcuff-like element 10 includes a pair of
generally rigid jaw members 14, 16 each having a proximal hinge end 18, 20,
respectively, and a distal attachment end 22, 24, respectively. In the
embodiment shown in FigsJ and 2, hinge ends 18, 20 are directly connected
together by a rivet 26 which functions as an axle to allow the jaw members 14,
16 to pivot relative one another between the wide open position shown in Fig.
1 and the closed position shown in Fig. 2, as will be readily understood.
The proximal aspect 28 of jaw member 14 has an inner
retaining surface 30 and an outer press surface 32 extending from hinge end
18 towards attachment end 22. The distal aspect 34 of jaw member 14
extends from proximal aspect 28 at an angle to give jaw member 14 an overall
C-shape. The upper surface 36 of distal aspect 34 of jaw member 14 is
serrated with teeth as at 38 for purposes to be described hereinafter. The
proximal aspect 40 of jaw member 16 has an inner retaining surface 42 and an
outer press surface 44 extending from hinge end 20 towards attachment end
24. The distal aspect of jaw member 16 defines a housing 46 with an arced
passageway 48 extending between distal tip 50 and back ledge 52. Extending
into passageway 48 is a tang 54 attached to an actuator button 56 resiliently
mounted to housing 46 and extending tlirough an aperture 58 in upper surface
60 of housing 46.
In both jaw members 14 and 16, the inner retaining surfaces 30
and 42 have a gentle arc such that in the wide-open position as shown in Fig.
1, almost the entire extent of the inner surfaces are not facing one another,
except perhaps adjacent the distal aspects of the respective jaw members.
The generally rigid nature of the jaw members 14, 16, and the
function of axle 26 allow the jaw members to operate in certain ways that are
advantageous for handling or storing bundled items. To this end, the wide
open position shown in Fig. 1 is self-sustaining in that handcuff-like element
10 will retain that wide-open position with the attachment ends spaced well
apart to define a bundle-receiving space 70 therebetween, and with the inner
retaining surfaces 30 and 42 generally not facing each other as above-
described. Rivet 26 pushes confronting surfaces of the hinge ends 18 and 20
together so as to maintain a frictional engagement therebetween thus holding
element 10 in the open position. Similarly, the jaw members 14, 16 are self-
aligned in that application of pressure to the press surfaces 32 and 44 will
cause the jaw members to move together along a generally fixed path or
trajectory (as indicated by double-headed arrow T) that effectively insures that
attachment end 22 of jaw member 14 will be received into attachment end 24
of jaw member 16 as the jaw members 14,16 are urged together without need
for extra manipulation. As jaw members 14,16 continue to be pushed
together, attachment 22 engages with attachment end 24 in the closed position
JO- shown in Fig. 2 with the inner retaining surfaces 30 and 42 confronting one
another.
To facilitate maintaining handcuff-like element 10 in the closed
position as shown in Fig. 2, teeth 38, which may be backwardly directed as
shown in Fig. 1, cooperate with tang 54 such that as attachment end 22 of jaw
member 14 passes into passageway 48, tang 54 rides over teeth 38 and notches
therein to generally prevent jaw member 14 from coming loose from
attachment end 24 of jaw member 16. Actuating button 56 by pressing on
surface 57 thereof causes tang 54 to momentarily lift upwardly relative
passageway 48 and out of engagement with teeth 38 to allow handcuff-like
element 10 to be opened.
Handcuff-like element 10 may be made of polymer materials
such as a durable and resilient plastic (such as ABS), ceramics, metal, or other
conventional materials such as wood, or a combination of two or more
conventional materials, using conventional manufacturing techniques. Where
both metal and plastic are used, the axle (e.g., rivet 26) and tang 54, for
example, would be metal with the rest made of plastic.
In use, an elongated item such as an electrical cord 12 is to be
stored as a bundle (i.e., with several elongated segments S in overlapped
condition) with handcuff-like element 10. To this end, the thickness or width
W of item 12 is to be increased many- fold (while the length thereof is greatly
decreased) by bundling the item 12 in known fashion. For example, cord 12
may be folded back and forth along itself as indicated in Figs. 3 A - 3D, such
-l ias by folding the cord in half (Fig. 3B) and then in half again (Fig. 3C). The
folding in-half process may be repeated as desired until the cord 12 is a bundle
as preferred by the user. Alternatively, short lengths or segments S of cord 12
may be folded over and over into a bundle as exemplified by Fig. 3D, or cord
12 may be coiled around the hand or fingers and then pressed together with
the same result. As a consequence, there is formed a bundle having a bundled
width WB many times (e.g., at least 2 although advantageously at least 4 to 8
or more) greater than width W. Bundled cord 12 may be attached to a useable
device such as a PC 80 as in Fig. 10, either before or after being bundled, and
either before or after being clamped as will now be described.
Jaw members 14, 16 are spread apart into the self-sustaining
open position shown in Fig. 1 whereat no further pressure is needed by the
user on jaw members 14 or 16 to retain the open position. While handcuff-
like element 10 is in that self-sustained open position, the bundle (such as
bundled cord 12 of Fig. 3C or Fig. 3D) is inserted into handcuff-like element
10 through bundle-receiving space 70, either by pushing the bundle into
element 10, or by passing open element 10 over the bundle. Thereafter,
pressure is applied against press surfaces 32 and 44 in conventional fashion to
cause jaw members 14, 16 to engage at their attachment ends 22, 24, until
inner retaining surfaces 30 and 42 have grasped against bundled item 12 as
shown in dotted line in Fig. 2. The bundled cord 12 is thus held in a small
compact bundle, even while in use as in Fig. 5, with easy manipulation of a
handcuff-like element and without difficult-to-use and unsightly items as
provided in the prior art.
Additionally, surfaces 32, 44, and/or 46 are relatively wide and
so may be labeled with indicia (as at 90 or 92). These indicia bearing surfaces
may be provided with labels bearing advertisements, directions or indicators
of the product being clamped (e.g., Christmas lights, extension cord, PC cable,
etc.). The labeling may be permanent or temporary and may be applied by
embossing, hot stamping, pad printing, stickers, or hand-written with marker.
With reference to Fig. 4, an alternative embodiment of a
handcuff-like element 100 is shown which may be used in the method of the
present invention. To this end, jaw members 114, 116 are like jaw members
14, 16 except that hinge ends 118 and 120 are not connected together by an
axle, but instead are connected together by a hinge strap 140. Handcuff-like
element 100 (including hinge strap 140) may be made of the same plastic as
handcuff-like element 10 but with less plastic in the hinge strap 140 due to
complementary recesses in the hinge ends 118 and 120 of the jaw members
1 14, 1 16, so that hinge strap 140 may bend when jaw members 114 and 1 16
are pivoted together into the closed position (like that shown in Fig. 2).
Alternatively, as shown in Fig. 5, hinge strap 140 could be
made from a different grade or type of plastic. In that instance, a rotational
press (not shown) may be used wherein two or more different types or grades
of plastic are injected into the same cavity into two or more different areas to
make an integral product. In this way, most of handcuff-like element 100'
may be made of a less flexible plastic, while hinge strap 140' is made of a
more flexible plastic. Alternatively, the same plastic may be cured differently
so that most of handcuff-like element 100' is less flexible, while hinge strap
140' is more flexible. In this embodiment, complementary recesses need not
be included in the area of hinge strap 140' to reduce the amount of plastic in
the hinge strap 140', as a more flexible plastic is used in that area permitting
flexible closure of the element 100'.
The resiliency/flexibility of strap 140 tends to force jaw
members 1 14,116 into the open position such that handcuff-like element 100
tends to automatically assume an open position (like Fig. 1 ) when it is not
closed. Operation of handcuff-like elements 100 and 100' is otherwise
substantially identical to that of handcuff-like element 10.
Due to the potential for slight misalignment of attachment end
22 and passageway 48 when the element 100' of Fig. 5 is closed, the
passageway 48 may incorporate a guide area 150 at its opening where
attachment end 22 is received. This guide area provides a large opening for
receiving attachment end 22, which has beveled sides for guiding attachment
end 22 into passageway 48 when element 100' is closed about a bundle. A
similar or alternate guide area may be used in this or the other embodiments of
the present invention shown in other Figs.
Referring to Fig. 6, in still another embodiment of the
invention, an alternative element 151 includes a region 152 of a sufficiently
resilient plastic or other material that the entirety of region 152 will bow into a
curved shape when finger pressure is applied to the outer press surfaces 32'
and 44' of element 151. Here again, any slight misalignment between
attachment end 22 and passageway 48 when element 151 is brought to a
closed position, is corrected by guide area 150 which guides attachment end
22 into passageway 48.
Referring to Fig. 7, in a further embodiment, element 153 is
formed with a crease 154 in its center section, providing an area of greater
flexibility in the molded plastic structure such that when force is applied to
outer press surfaces 32" and 44", element 153 bends about crease 154, causing
attachment end 22 to self-align and insert into passageway 48. Here again, a
guide area 150 is included in passageway 48. It will be noted that a curve,
rather than a right angle bend, may be formed at the junction between the
distal aspect 34' and proximal aspect 28' of the jaw member shown in Fig. 7.
Moreover, teeth 38 may be formed over a longer distance, for example, along
the entire length from attachment end 22 throughout press surface 32" to
crease 154, permitting a wider range of adjustment when the jaw members are
in their closed position. Furthermore, crease 154 may be located at any point
between attachment end 22 and passageway 48, so long as end 22 and
passageway 48 self-align when end 22 and passageway 48 are pressed
together toward each other, potentially further increasing the range of
adjustment.
In the embodiments of the invention shown in Figs. 1 and 2,
complementary recesses are formed in jaw members 14 and 16. Referring to
Figs. 8 and 9, in further embodiments of a handcuff-like element 156 similar
to element 10 shown in Figs. 1 and 2, only one such recess 158 need be
formed in one of jaw members 14' or 14" and 16' or 16". In Fig. 8, a recess is
formed on jaw member 16', of sufficient dimensions to align attachment end
22 with passageway 48. In Fig. 9, a recess 159 is formed on jaw member 14",
of sufficient dimensions to align attachment end 22 with passageway 48.
Notably, no complementary recesses are formed in jaw member 14' of Fig. 8
or jaw member 16" of Fig. 9, as the dimensions of recesses 158 and 159 are
sufficient to align attachment end 22 with passageway 48.
Referring particularly to Fig. 9, it can be seen that the
engagement between the jaw members 14" and 16" may be maintained by
structure formed at the hinged interface between those members, rather than
by structure formed at the outer ends of those members. Specifically, as seen
in Fig. 9, jaw members 14" and 16" may include mating knurled teeth 161 at
their hinged ends 18" and 20", so that jaw members 14" and 16" frictionally
engage with a force sufficient to hold members 14" and 16" engaged together
tightly about a bundle. The frictional engagement between members 14" and
16" can be overcome by manual force applied to members 14" and 16",
causing knurled teeth 161 to slide past one another and permit the jaws to
close or open. It will be appreciated that a similar frictional engagement at the
hinged ends 18 and 20 of the handcuff-like element can be used in any of the
embodiments and Figs, discussed herein. Furthermore, other frictional
engagement structures, such as a mechanical rachet, could also be used at the
hinged connection between the jaw members in any of the embodiments and
Figs, discussed herein. Also, the surfaces at the hinged ends 18 and 20 of the
jaw members may be relatively smooth, but held together tightly by the rivet
26 so that a substantial static friction is generated between the two, thus
holding the members in their closed or open position once manually moved to
that position.
It will be appreciated that the structure which retains the jaw
members (14, 16) in engagement, may or may not be releaseable. In
applications where the disclosed structures will be used relatively permanently
(e.g., in electronics manufacturing), a releaseable engagement is not necessary,
and thus non-releasable structures may be used, e.g., actuator button 56 for
releasing tang 54 in the retaining structure shown in Figs. 1, 2, 4, 5, 6, 7 and 8,
may be eliminated, possibly reducing the cost of manufacture. Other non-
releaseable mechanical or frictional engagement structures can also be used.
Referring now to Fig. 11 , in a seventh alternative embodiment
of a self-aligning device 170 for handling or storing bundled items, the teeth
172 on one of the jaw members are positioned on the side of the jaw member
and the tang 174 that holds the jaw members in engagement is formed in the
side of an opposite jaw member. In this embodiment the tang and the jaw
member are formed as a one-piece construction. The 174 tang is molded to
engage the teeth 172 when in its rest position. Spring force urging the tang
into engagement with the teeth on the opposite jaw member is created by the
resilience of the plastic material used to mold the jaw member.
Referring now to Fig. 12, in an eighth alternative embodiment
of a self-aligning device 180 for handling or storing bundled items, the tang
182 is formed internally of an end of a jaw member such as is commonly done
in conventional wire-ties. In this embodiment, the teeth 184 on the opposite
jaw member cannot be readily removed from the tang 182 once engaged.
Referring to Fig. 13, in a ninth alternative embodiment of a
self-aligning device 186 for handling or storing bundled items, the tang 187
similarly is formed internally of an end of a jaw member such as is commonly
done in conventional wire-ties. However, in this embodiment, the teeth 188
are on the inner surface of the opposite jaw member, and the tang 187 is
oriented to engage the teeth on the inner surface rather than the outer surface.
It will be appreciated that this embodiment cannot be readily removed once
closed about an object. In this embodiment, the jaw members are connected
together by a hinge strap 189. Hinge strap 189 could be made from a different
grade or type of plastic. In that instance, a rotational press (not shown) may
be used wherein two or more different types or grades of plastic are injected
into the same cavity into two or more different areas to make an integral
product. In this way, most of the jaw members, may be made of a less flexible
plastic, while hinge strap 189 is made of a more flexible plastic.
Alternatively, the same plastic may be cured differently so that most of jaw
members are less flexible, while hinge strap 189 is more flexible.
Various engagement mechanisms can be used on the ends of
the jaw members. Referring now to Figs. 14 and 15, in one alternative
mechanism, the tang 196 is formed at the end of a mechanical slider 190.
Slider 190 moves within a channel 192 at an end of one of the jaw members.
Channel 192 is formed between an outer end of one jaw member 193 and an
end cap 195 mounted thereto. Slider 190 is sized such that when tang 196 is
disengaged with the teeth on the mating jaw member 198, upper end 194 of
slider 190 extends outward from the jaw member. The jaw member includes a
channel 199 through which the mating jaw member 198 passes when the
device is in its closed position. When slider 190 is inserted fully into channel
192, as seen in Fig. 14, the end of the slider 190 carrying tang 196 passes into
channel 199 and engages with teeth of the mating jaw member 198.
Slider 190 defines a latch 202 on its lower end. When slider
190 is fully inserted into channel 192, latch 202 will catch on an upper wall
surface 204 of channel 199. A spring 200 captured within channel 192
generates spring force driving slider 190 toward its disengaged position.
Spring 200 also generates a torque tending to rotate slider 190 to facilitate
engagement between latch 202 and upper wall surface 204 of channel 199.
A release button 206 included within the engagement
mechanism can be utilized to disengage latch 202 from upper wall surface
204, and thereby cause slider 190 to move upward to its disengaged position
shown in Fig. 14 due to spring force generated by spring 200.
In use, slider 190 is placed in its disengaged position by
pressing release button 206 if necessary. Next, the mating jaw element 198 is
passed through channel 199 until it reaches the desired position. Then the
upper end 194 of slider 190 is pressed until latch 202 engages to the upper
wall surface 204, holding slider 190 in its engaged position. To release,
button 206 is pressed, causing spring 200 to push slider 190 to its disengaged
position.
Fig. 16 illustrates a second alternative engagement mechanism.
In this mechanism, a rotatable element 208 is molded into an end of a jaw
element. Element 208 has, on an outer end, a pressure surface 210, and has,
on an inner end, a tang 212 for engaging teeth on the opposite jaw element.
Element 208 is molded such that in an unstressed condition tang 212 will
engage the teeth of the opposite jaw element. By pressing on pressure surface
210, element 208 will be rotated, bringing tang 212 out of engagement and
releasing the opposite jaw element.
It will be appreciated that a device in accordance with the
present invention can incorporate additional features to facilitate use. For
example, a device 214 in accordance with principles of the present invention
may incorporate an integral clip 217 on the side of a jaw member as seen in
Fig. 17, allowing the device to be clipped to an electrical cord or other item.
As further illustrated in Fig. 17, the device 214 may have a hole 216, so that
the device can be hung on a hook, or a string or shock cord can be used to tie
the device 214 down or tie the device 214 to the item(s) with which it will be
used.
Clips can take various forms or be in various positions. As
seen in Fig. 18, in an alternative device 218 one of the jaw members has a dual
dual clip 220 on its outer surface. Alternatively, as shown in shadow on Fig.
18, a single clip can be formed in another position on the outer surface of a
jaw member. Alternatively, or in addition, as seen in Fig. 18, the device may
have a slot 226 in a jaw member, allowing the device to be clipped to an
electrical cord of other item. Slot 226 as shown is C-shaped in cross section,
but could also have other shapes such as a T-shaped cross section.
Furthermore, one of the jaw members may have a hook or hanger 228.
Furthermore, as seen in Figs. 19-24, an alternative device 230
may further include a handle 232 to facilitate handling of items captured
between the jaw members. Handle 232 may be integral to the device or
removable.
Although the bundled item (12) is shown in the preceding
figures as a single elongated item folded over upon itself, it will be
appreciated that a bundle could alternatively refer to a plurality of separate,
typically but not necessarily elongated items held together as a bundle.
Furthermore, a flat object such as a cloth napkin may be bundled and handled
or stored by gathering the flat object together into a bundle and capturing the
bundle in the same manner as a bundled electrical cord. Consequently,
whether multiple overlying segments of one item define the bundle or multiple
items define the bundle, each of which would appear as in Fig. 2, the result is
a bundle that has a width or thickness substantially greater than any one item
in the bundle.
Several applications are possible. As seen in Fig. 19, the
device 130 may be used in handling or storing a bundle of key rings each
carrying one or more keys 234, by passing one of the jaw members through
the key rings. As seen in Fig. 20, the device 130 may similarly be used to
handle or store a bundle of belts 236 by passing one of the jaw members
through the belt buckles. Fig. 21 illustrates the device 130 used to handle or
store bundled fabric 238, which may be clothing or other fabrics such as a
napkin. Fig. 22 illustrates the device 130 used to store or handle items of
jewelry 240 by passing one of the jaw members through each item of jewelry.
As seen in Fig. 23, the device 10 may also facilitate carrying bags such as
handled shopping bags 242, by passing one of the jaw members through the
gathered bag handles. The device may also be used to cinch closed the
gathered top of a bag or sack such as a laundry bag, garbage bag, or food (e.g.
potato chip) bag, mail bag, garden product bag in the manner in which twist
ties are presently used. As seen in Fig. 24, the device 130 may further be used
to gather a planting 244, e.g. by wrapping the device around a gathered
planting 244 and supporting stake 246. Alternatively, the device may be used
in training a planting by binding two parts of the planting together. Further,
the device may be used in mending a break in a planting or in grafting
plantings by closing the device about the broken planting in the area of the
break or about the grafted plantings in the area of the graft. As a further
alternative, the device may be used as a child safety device, e.g., by using the
device to bundle together the handles of a cabinet door, or otherwise bundle
together objects so that they cannot be unbundled by a child. The device may
also be worn as a jewelry or a similar personal adornment, e.g., by closing the
device about body parts or clothing worn on the body, or both, so that the
device is visible.
Additionally, various structural changes are possible. For
example, serrated teeth and the tang may be replaced with other cooperating
latch elements as will be apparent. Similarly, less pronounced, or a different
number of teeth may be employed. So, too, rivet 26 may be replaced with a
screw or self attaching clip or the like. In the element 100, hinge strap 140
may be formed by ultrasonically welding jaw members 1 14, 1 16 together at
their hinge ends. Further, handcuff-like element 10 may be provided with a
spring loaded hinge and/or locking device (both not shown) to assist in
keeping the jaw members 14, 16 in the open position without external pressure
as is accomplished with hinge strap 140 of element 100. Also, the handcuff-
like element may be manufactured separately from the bundled item with
which it is used, or may be attached to the item with which it is to be used,
e.g., the handcuff-like element may be permanently attached by a strap or
string to an electrical cord for use in bundling the electrical cord, or may be
partially or wholly formed as part of the object being bundled, e.g., partially
formed in the plug of an electrical cord.
