Abstract
A shoelace locking apparatus. The apparatus comprises a body attachable to a first end of a shoelace and a cup. The body defines a laterally opening locking passage therein for receiving a second end of the shoelace. The cup may be integral with the body or with a separate extension component. By tying a knot in a desired location in the second end of the shoelace and stretching the lace, the second end of the lace may be moved into an engaged position in which tension in the stretched lace tends to maintain the knot in the cup. The apparatus may also comprise a lock attachable to the second end of the shoelace such that the lock is also positioned in the cup and rotatable to a locking position preventing undesired longitudinal movement of the lock and shoelace.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to fastening or locking devices for shoelaces, and more particularly, to a shoelace fastening apparatus for quickly fastening and releasing the two ends of a shoelace without the necessity of tying a knot with the ends.
2. Description of the Prior Art
It is well known that shoelaces require tying and untying the two ends thereof at every use, and many times the laces come undone prematurely which, of course, is not desired. Also, tying of shoelaces is difficult or impossible for some wearers. For example, parents may be required to spend time and exertion tying young children's laces. Once tied, children may play with the knot, step on a lace end, or otherwise cause the laces to work free through normal walking. For children and adults, laces which come undone prematurely represent at best more work to retie and at worst an opportunity for a tripping accident. Also, persons with problems with manual dexterity, such as arthritis sufferers, may find tying shoelaces to be difficult if not impossible. The present invention solves these problems by providing a shoelace fastening device which users can operate with much less effort, dexterity and time than is necessary for tying laces and which eliminates the possibility of premature unfastening.
A variety of devices have been developed for locking shoelaces without requiring the tying thereof. For the most part, these devices are overly complicated such that they are not practical and can necessitate a portion of the apparatus be physically attached to the shoe, thus either requiring that the device be made an integral part of the shoe originally or requiring a permanent modification of the shoe subsequently. The present invention does not require any changes to the shoe itself, but is quickly and easily attached and detached only from the shoelaces. Thus it is applicable to all laced shoes currently in the stream of commerce and easily transferable between pairs of shoes.
A problem with previous quick-release shoelace locks is that they may accidentally become disengaged relatively easily. As with tied laces, if a locking device is too easy to release, young children may take them off when it is desired that they not do so. The present invention solves this problem by providing a locking mechanism which guards against unwanted manipulation by children. This child-proof feature should provide a boon to parents who probably already have their hands full in dealing with young children without being concerned about keeping their shoes on.
Another problem with previous quick-release shoelace locks is that those that are not integral with the shoe may easily come entirely separated from the shoe when not in use. This invention solves that problem by providing a method of attachment to one end of the lace that does not release when the device is not in use, and therefore prevents the unintended separation of the device from the shoe. At the same time, complete separation is possible if desired.
Finally, an optional extension further assists in the manipulation of the device by handicapped users.
SUMMARY OF THE INVENTION
The present invention is a device for fastening and locking shoelaces. Different embodiments are described herein, but all primarily utilize on the tension inherent in a stretched shoelace to hold the apparatus in its engaged position and secondarily utilize mechanically interlocking components to resist tampering.
The invention may be described as an apparatus for connecting ends of a shoelace comprising a body adapted for attachment to a first end of the shoelace and a cup adapted for receiving a knot tied in the second end of the shoelace such that tension in the shoelace tends to hold the knot in the cup. The body defines a laterally opening locking passage therein adapted for receiving a second end of the shoelace. The body further preferably defines a retaining passage therein adapted for receiving the first end of the shoelace therethrough. A knot tied in the first end of the shoelace is prevented from passing through the retaining opening because of the size thereof.
The body may have a protrusion thereon adjacent to the locking passageway for reducing a portion of the locking passage in size and thereby providing resistance to movement of the second end of the shoelace therethrough.
In a first embodiment, the cup is integrally formed with the body and disposed at an end of the locking passage. Normally, when in a locking position, the knot tied in the second end of the shoelace engages a shoulder in the cup. Alternatively, the apparatus may further comprise a lock adapted for attachment to the second end of the shoelace and positionable in the cup. The lock has a locking position substantially preventing inadvertent removal thereof from the cup. As illustrated herein, the body further comprises a lock retainer in the cup, and the lock has a notch thereon. Longitudinal movement of the lock in the cup is possible when the notch is aligned with the lock retainer, and longitudinal movement of the lock in the cup is substantially prevented when the lock is rotated with respect to the body to the locking position. The notch and lock retainer are substantially flat. The lock preferably has a knurled edge thereon.
In a second embodiment, the apparatus further comprises an extension separable from the body and positionable in a locking position adjacent to an end of the locking passage in the body. The cup is integrally formed with the extension. The body defines a recess at an end of the locking passage, and a portion of the extension extends into the recess when in the locking position. Lateral movement of the extension is prevented when the extension is in the engaged position.
The first embodiment of the invention may also be described as an apparatus for connecting ends of a shoelace comprising a body adapted for attachment to a first end of the shoelace and defining a locking passage therein adapted for laterally receiving a second end of the shoelace, and a lock adapted for attachment to the second end of the shoelace and positionable in a locked position in the locking passage. The locking passage comprises a cup in which the lock is positioned when the lock is in the locked position. The locking opening also has an elongated portion extending from the cup. The cup and elongated portion of the locking passage are in communication with a laterally opening slot defined in the body.
The first embodiment of the shoelace locking apparatus of the present invention may also be described as comprising a body defining a first opening therein for longitudinally receiving a first end of the shoelace therethrough, a second opening for receiving a second end of the shoelace therein, and a laterally opening slot in communication with a second opening. The second opening has an elongated portion and an enlarged portion with the enlarged portion being adapted for receiving a knot tied in the second end of the shoelace. The second end of the shoelace may be moved laterally through the slot into the second opening such that the knot tied in the second end of the shoelace may be subsequently moved longitudinally into the enlarged portion of the second opening. This slot is sized such that lateral movement of the knot therethrough is prevented.
The second embodiment of the shoelace locking apparatus may be described as comprising a body and an extension. The body defines a first opening therein for longitudinally receiving a first end of a shoelace therethrough, a second opening for receiving a second end of the shoelace therein, a recess in communication with an end of the second opening, and a laterally opening slot in communication with the second opening and recess such that the second end of the shoelace may be moved laterally through the slot. The extension is adapted for receiving the second end of the shoelace therethrough and has an enlarged portion for receiving a knot tied in the second end of the shoelace. The extension has a portion adapted for extending into the recess in the body when the extension is in a locking position. The extension is sized such that lateral movement thereof through the lateral opening slot in the body is prevented. Tension in the shoelace tends to hold the extension in the engaged position.
An important object of the present invention is to provide a shoelace fastening apparatus which quickly and easily may be used to tighten and release shoelaces.
Another object is to provide a shoelace fastening device which can be used with any existing laced shoe without reinforcement, retrofitting or modification of the shoe, and which can be easily transferred between shoes.
Another object of the invention is to provide a positive shoelace fastening system that is not susceptible to the forces and dynamics which tend to loosen the slip knots commonly employed when tying shoes.
A further object of the invention is to provide a shoelace fastening device which requires a simple, deliberate action on the part of the user to disengage it.
Another object of the invention is to provide a locking device for preventing young children and toddlers from unfastening their shoes.
Still another object of the invention is to provide a shoelace locking device which is secured to the shoelace even when not in use so that the locking device is not easily lost.
An additional object of the invention is to provide a shoelace locking device which allows an opportunity for fashion statements and/or advertising on shoes as a result of the design of the locking device.
Numerous other objects and advantages of the invention will become apparent as the following detailed description of the preferred embodiments is read in conjunction with the drawings which illustrate such embodiments.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Different embodiments of the apparatus will now be described. In all of the embodiments, the fastening apparatus of the present invention places the shoestring in tension and uses this tension to hold the apparatus in the engaged position. This is accomplished by positioning a knot in the shoelace in a cup portion of the apparatus. This cup prevents inadvertent removal of the knot therefrom so that the shoelace is positively engaged by the apparatus when the apparatus is in the engaged position and may only be released when the apparatus is placed in an disengaged position.
Referring now to the drawings, and more particularly to
FIG. 1
, a first embodiment of the shoelace fastening or locking apparatus of the present invention is shown and generally designated by the numeral
10
. Apparatus
10
is adapted for use in releasably connecting ends of a shoelace
12
of a shoe
14
. As shown in
FIG. 1
, shoe
14
includes a sole
16
, an upper
18
and a tongue
20
in addition to shoelaces
12
. However, it will be understood by those skilled in the art that shoelace locking apparatus
10
may be used with any of a variety of shoe constructions using laces, and the invention is not intended to be limited to the shoe configuration illustrated in FIG.
1
. In other words, apparatus
10
is used to connect a first end
22
and a second end
24
of virtually any shoelace
12
.
In the drawings, first embodiment shoelace locking apparatus
10
is shown having a body
26
and a lock
28
. As will be further described herein, lock
28
is actually an optional component and is not necessary for a functioning shoelace fastening device. However, lock
28
provides a more secure connection and one which is much less likely to be circumvented by small children.
Referring now to
FIGS. 2-6
, the details of apparatus
10
will be discussed.
Body
26
is preferably of a one-piece construction. In particular, but not by way of limitation, it is contemplated that body
26
could be easily molded of a plastic material. However, other materials would work just as well. Also, body
26
could be formed of multiple pieces.
Body
26
is illustrated as having a generally parallelepiped configuration. However, body
26
does not have to be any particular shape, and it is contemplated that it can be molded into a variety of shapes to provide ornamentation as a fashion statement or to provide a medium for placing advertising thereon. Regardless of the shape or configuration of body
26
, the body preferably defines a first passage or opening
30
extending longitudinally therethrough and a second passage or opening
32
extending longitudinally therethrough and substantially parallel to the first passage.
First passage
30
is generally a cylindrical opening adapted for receiving first end
22
of lace
12
therethrough. As seen in
FIGS. 1 and 6
, by tying a knot
34
in first end
22
of lace
12
after passing the lace through first passage
30
, body
26
is retained on the first end of the lace, and knot
34
prevents the lace from being pulled back through because of the engagement of the knot with a first end
36
of body
26
. Thus, first passage
30
may be referred to as retaining passage
30
.
Second passage
32
comprises an elongated portion
38
and an enlarged portion
40
which is adjacent to a second end
42
of body
26
. Enlarged portion
40
may also be referred to as a cup
40
which is integrally formed with body
26
. The cup may also be in an extension component separable from the body, as described in the second embodiment herein.
As best seen in
FIGS. 4 and 5
, a longitudinally extending slot
44
provides lateral communication between second passage
32
and side
46
of body
26
. Thus, it may be said that second passage
32
opens laterally with respect to body
26
.
Slot
44
is shown extending at approximately 90E from side
46
, but as an alternative could be at a different angle so that simply pulling sideways on shoelace
12
will not release it. Rather, lace
12
would have to be pulled at the angle of slot
44
with the object to make inadvertent disengagement less likely.
Except where intersected by slot
44
, elongated portion
38
of second passage
32
is generally cylindrical. Enlarged portion or cup
40
of the second passage is also cylindrical and has a diameter larger than that of the elongated portion
38
. Thus, a shoulder
48
, having an annular configuration truncated by slot
44
, extends between elongated portion
38
and enlarged portion
40
of second passage
32
.
As best seen in
FIGS. 4-6
, a first or upper lock retainer
50
and a second or lower lock retainer
52
are disposed in enlarged portion or cup
40
of second passage
32
. First and second lock retainers
50
and
52
are spaced longitudinally from shoulder
48
such that a gap
54
is defined therebetween. As will be further discussed herein, gap
54
is slightly larger than the thickness of lock
28
so the lock can fit therein. Referring to
FIGS. 4 and 5
, first and second lock retainers
50
and
52
are substantially flat and extend as chords with respect to the partial circle defined by enlarged portion
40
of second passage
32
.
Adjacent to first end
36
of body
26
, a pair of facing protrusions
56
extend inwardly in slot
44
. As will be further described herein, protrusions
56
serve to lightly retain a portion of second end
24
of shoelace
12
in body
26
adjacent to the protrusions.
Referring now to
FIG. 3
, lock
28
is generally in the form of a substantially flat disc defining a central hole
58
therethrough. Lock
28
is generally circular with an outer edge
60
which is preferably knurled. A first or upper notch
62
and a substantially parallel second or lower notch
64
truncate the generally circular configuration of lock
28
and extend as chords thereacross. The spacing between first and second notches
62
and
64
is slightly less than the spacing between first and second lock retainers
50
and
52
.
In the operation of apparatus
10
, regardless of whether lock
28
is used, first end
22
of shoelace
12
is extended longitudinally through first, retaining passage
30
in body
26
, and knot
34
is tied in the lace as previously described to attach and retain body
26
to the shoelace.
As previously mentioned, lock
28
is optional. When lock
28
is not used, a knot
66
is formed in second end
24
of shoelace
12
at the desired position. Shoelace
12
is stretched along the length of body
24
with knot
66
clearing second end
42
of body
26
, after which second end
24
of the shoelace may be moved laterally inwardly through slot
44
into second passage
32
. By tying knot
66
in the appropriate position along the length of second end
24
of shoelace
12
, the stretching of lace
12
will result in enough tension being applied to it so that the lace pulls knot
66
toward shoulder
48
in body
26
. Knot
66
thus directly engages shoulder
48
in body
26
, and is held there by the tension in stretched shoelace
12
, thereby retaining second end
24
of shoelace
12
in body
26
and fastening lace
12
on shoe
16
. Thus, second passage
32
may be referred to as fastening passage
32
. This is a satisfactory arrangement when it is not necessary or desired to more securely lock shoelace
12
into apparatus
10
. Removal is accomplished simply by pulling longitudinally outwardly on second end
24
of lace
12
, so that knot
66
clears end
42
of body
26
, and moving the lace back transversely outwardly through slot
44
so that it is disengaged from body
26
.
In the operation of the embodiment of apparatus
10
utilizing lock
28
, second end
24
of shoelace
12
is passed through hole
58
in lock
28
. As seen in
FIGS. 1 and 6
, a knot
66
is formed in second end
24
of shoelace
12
to retain lock
28
thereon.
Second end
24
of lace
12
is positioned in body
26
and locked therein in the following manner. Second end
24
of lace
12
is stretched longitudinally beside body
26
(toward the right in
FIG. 1
) so that knot
66
and lock
28
are beyond second end
42
of body
26
. At this point, second end
24
of lace
12
may be moved laterally inwardly into second passage
32
through slot
44
. In this way, lock
28
and knot
66
are generally aligned with enlarged portion or cup
40
of second passage
32
so that the lock and knot
66
may be moved longitudinally into the cup (to the left in FIGS.
1
and
6
). By tying knot
66
in the appropriate position along the length of second end
24
of lace
12
, the stretching of lace
12
will result in enough tension being applied to it so that the lace tends to pull lock
28
and knot
66
toward shoulder
48
in body
26
.
Referring now to
FIGS. 4 and 6
, notches
62
and
64
on lock
28
are aligned with lock retainers
50
and
52
in body
26
so that lock
28
may be moved longitudinally into gap
54
. As seen in
FIG. 5
, lock
28
may be rotated 90E in gap
54
so that notches
62
and
64
are no longer aligned with lock retainers
50
and
52
. In
FIG. 5
, lock
28
is shown after being rotated clockwise 90E, but those skilled in the art will see that the lock could just as easily be rotated counterclockwise. In this locking position, lock retainers
50
and
52
will be seen to prevent longitudinally outward movement of lock
28
. Thus, lace
12
is locked on shoe
16
, and second passage
32
may be referred to in this embodiment as locking passage
32
.
When so engaged, the portion of second end
24
of shoelace
12
adjacent to protrusions
56
is lightly retained in body
26
as previously described. The flexible material of the typical shoelace
12
allows it to be passed fairly easily between protrusions
56
, but the lace will not simply fall therethrough.
To release second end
24
of shoelace
12
, lock
28
is rotated back 90E in either direction so that notches
62
and
64
are each aligned with one of lock retainers
50
and
52
, at which point pulling on the end of the shoelace will move knot
66
and allow lock
28
to pass between retainers
50
and
52
and then longitudinally outwardly through cup
40
. Once knot
66
and lock
28
clear end
42
of body
26
, second end
24
of shoelace
12
may be moved laterally outwardly through slot
44
so that it is disengaged from body
26
.
FIGS.
2
and
4
-
6
also illustrate another alternate construction. In this embodiment, at least one divot
68
is indented into the surface of shoulder
48
in body
26
. As illustrated, there are four such divots
68
, but the invention is not intended to be limited to any particular number. A corresponding number of raised bumps
70
are formed on lock
26
in the same spacing as divots
68
. At least when lock
28
is positioned in the locking position shown in
FIG. 5
, bumps
70
on the lock are aligned with divots
68
in body
26
and extend therein to help prevent inadvertent rotation of lock
28
within enlarged portion
40
of second passage
32
in body
26
. Thus, in this alternate embodiment, resistance is provided against rotation of lock
28
, but this resistance is easily overcome by simultaneously relieving the bearing pressure of the knot
66
on the lock
28
while rotating the lock
28
. In this way an advanced level of mental and physical ability is required to rotate the lock
28
while chance movement is substantially eliminated.
With or without divots
68
and bumps
70
, a degree of manual dexterity is required to rotate optional lock
28
to its unlocked position. To unlock apparatus
10
with lock
28
, one pulls on lace
24
so that knot
66
no longer exerts a longitudinally directed force on lock
28
, rotates lock
28
so that notches
62
and
64
are again aligned with lock retainers
50
and
52
, and guides lock
28
with knot
66
outwardly from body
26
until both clear the end
42
. Adults will be able to carry out these steps in order to move lock
28
to the unlocked position, but small children and toddlers will not as likely be able to do so. Thus, a parent can fasten a child's shoelaces, and the child will be deterred from disengaging the shoelaces and removing the shoes.
In still another variation of apparatus
10
, a cap
70
may be positioned over enlarged portion
40
of second passage
32
as shown in phantom lines in
FIG. 2
to enclose knot
66
and also lock
28
if present. Cap
70
could be tethered to body
26
, such as by being molded as an integral, flexible part of the body or as a separate piece attached thereto.
Referring now to
FIG. 9
, a second embodiment of the shoelace locking apparatus of the present invention is shown and generally designated by the numeral
100
. As with first embodiment apparatus
10
, second embodiment apparatus
100
is adapted for use in releasably connecting first and second ends
22
and
24
of a shoelace
12
.
Apparatus
100
comprises a body
102
and an extension or knob
104
. Body
26
is preferably of a one-piece construction, such as molded plastic, but other materials and multiple pieces would also work.
Body
102
is illustrated as having a generally parallelepiped configuration, but does not have to be of any particular shape. It is contemplated that body
26
may be molded into a variety of shapes to provide ornamentation as a fashion statement or to provide a medium for placing advertising thereon. Regardless of the shape or configuration of body
102
, the body preferably defines a first passage or opening
106
extending longitudinally therethrough and a second passage or opening
108
extending longitudinally therethrough and substantially parallel to the first passage.
As in first embodiment apparatus
10
, first passage
30
in second embodiment
100
is generally a cylindrical opening adapted for receiving first end
22
of lace
12
therethrough. As seen in
FIG. 9
, by tying a knot
34
in first end
22
of lace
12
after passing the lace through first passage
106
, body
102
is retained on the first end of the lace, and knot
34
prevents the lace from being pulled back through because of the engagement of the knot with a first end
110
of body
102
. Thus, first passage
106
may be referred to as a retaining passage
106
.
Second passage
108
comprises an elongated portion
112
and an enlarged recess
114
adjacent to a second end
116
of body
102
. As illustrated in
FIG. 9
, body
102
is identical to body
26
in first embodiment apparatus
10
, and the previously described enlarged portion
40
is the same as recess
114
in the second embodiment. However, the invention is not intended to be limited to the specific body illustrated, and bodies
102
and
26
need not be identical.
A longitudinally extending slot
118
provides lateral communication between second passage
108
and one side of body
102
. Thus, it may be said that second passage
108
opens laterally with respect to body
102
.
Slot
118
preferably extends at approximately 90E from the side of body
102
, but as an alternative could be at a different angle so that simply pulling sideways on shoelace
12
will not release it. Rather, lace
12
would have to be pulled at the angle of slot
118
with the object to make inadvertent disengagement less likely.
Except where intersected by slot
118
, elongated portion
112
of second passage
108
is generally cylindrical. Recess
114
is also cylindrical and has a diameter larger than that of elongated portion
112
. Thus, a shoulder
120
, having an annular configuration truncated by slot
118
, extends between elongated portion
112
and recess
114
of second passage
108
.
Referring also to
FIGS. 7 and 8
, extension
104
has a generally conical outer surface
122
extending from a cylindrical outer surface portion
124
. Cylindrical outer surface portion
124
is adapted to fit within recess
114
, as seen in
FIG. 9
, when in a locking position, as will be further described herein.
Extension
104
defines a bore
126
therein which is approximately the same size as elongated portion
112
of second opening
108
in body
102
. Extension
104
also defines an enlarged opening or cup
128
which opens outwardly at an outer end
130
of the extension. An inner end
132
of extension
104
is adapted for engagement with shoulder
120
and body
102
when apparatus
100
is in the fastening position shown in FIG.
9
.
In the operation of second embodiment
100
, second end
24
of shoelace
12
is inserted through bore
126
in extension
104
. A knot
34
is formed in second end
24
of lace
12
and positioned such that it engages a curvilinear surface
134
in cup
128
. That is, knot
66
prevents second end
24
of lace
12
from being pulled back through bore
126
in extension
104
.
By grasping extension
104
on conical surface
122
thereof, extension
104
is easily pulled to stretch second end
24
of lace
12
so that the extension clears second end
116
of body
102
. Second end
24
of shoelace
12
may then be moved laterally inwardly through slot
118
into second passage
108
. Cylindrical outer surface
124
of extension
104
is aligned with recess
114
in body
102
, and the extension is released. The tension in stretched shoelace
12
will keep knot
66
engaged with cup
128
and pull cylindrical outer surface
124
of extension
104
into recess
114
such that inner end
132
of the extension engages shoulder
120
, thereby placing apparatus
100
in the engaged position shown in FIG.
9
. Thus, as with first embodiment
10
and its variations, the tension in shoelace
12
keeps second embodiment apparatus
100
in its engaged position. Disengagement is accomplished simply by pulling on extension
104
and reversing the process.
It will be seen, therefore, that the shoelace locking apparatus of the present invention is well adapted to carry out the ends and advantages mentioned as well as those inherent therein. While presently preferred embodiments of the apparatus have been shown for the purposes of this disclosure, numerous changes in the arrangement and construction of parts may be made by those skilled in the art. All such changes are encompassed without the scope and spirit of the appended claims.
