FIELD OF THE INVENTIONThe present invention generally relates to a product and method for replacing drawstrings as used in clothing and drawstring-closed items.
BACKGROUND OF THE INVENTIONMany types of apparel and products employ the use of drawstrings (including laces, ties, pull cords, elastic cords and other similar product closure devices) as a closure device and/or decorative feature. For instance products such as sweat pants, hoodies, jackets, boots, rain wear, gloves, tents, sleeping bags, school bags often use some form of drawstring to secure the product around its intended target. Typically with such products, the drawstrings are manufactured separately from the product and then installed in the product before the product is sold. Most often, the drawstring is passed through a narrow tubular enclosure (often referred to as a drawstring channel) provided on the product to contain the drawstring. Eyelets provide entrance and exit openings to the drawstring channel. Plastic fittings or aglets at either end of the drawstring help prevent fraying of the drawstring and make feeding the drawstring through the tubular enclosure easier.
The purchaser of the product has little choice but to use the drawstring that has been chosen and provided by the manufacturer in such products since removal and replacement of the lace is cumbersome. Oftentimes, the drawstrings that are provided with the product pull out, wear out, or just plain do not match the outfit the customer has purchased, and the unfortunate reality is that changing or replacing these drawstrings through the enclosure can be a time consuming and frustrating ordeal.
Devices exist to assist in inserting replacement drawstrings into a drawstring channel. Most devices, for instance U.S. Pat. No. 4,671,437 to Sauger et al. [Sauger], are pusher-type devices. In Sauger, an end portion of a drawstring to be inserted is folded over a leading end of a pusher device. A cap is placed atop the folded-over drawstring on the leading end of the pusher device and the pusher device is fed through the drawstring channel, pulling the replacement drawstring with it. One drawback with this type of device is that sometimes the channel cannot easily accommodate the combined widths of the cap, the pusher and the drawstring.
Pull-type devices, such as U.S. Pat. No. 5,447,260 to Beddow [Beddow] also exist. In Beddow, a long pulling member releasably captures an aglet of a drawstring to be inserted at the trailing end of the pulling member. In one embodiment, the aglet is screwed into a female connector of the pulling member. The female connector may contain a tapered threaded insert into which the aglet is screwed. With the replacement drawstring so attached, the leading end of the pulling member is inserted into and fed into and through the drawstring channel, pulling the replacement drawstring into the channel. Beddow overcomes the problem of width through the channel discussed above in Sauger, but adds the inconvenience of working with a long pulling member, which is recommended to be at least as long as the drawstring channel it is being used for.
The present invention allows someone easily to change a first drawstring within a drawstring channel of a product by joining one end of the first drawstring to an end of a second drawstring that will be pulled into the enclosure as the first drawstring is pulled out of the enclosure. In a preferred aspect the second drawstring is versatile in being able to join to that first drawstring, when it is a conventional drawstring having finished ends (e.g. finished with aglets), and also when it is another drawstring similar to the second drawstring.
As a secondary benefit the present invention can also allow opposite ends of a drawstring to be secured together to the lessen movement of the drawstring.
Further, the present invention can allow multiple drawstrings to be fastened end-to-end and/or in combination with decorative charms and the like.
SUMMARY OF THE INVENTIONIn one aspect of the invention, a closure means for a product is provided. The closure means includes a flexible elongate body such as a lace, drawstring, elastic, string, rope, wire, tie and strap. At least one connector is positioned on at least one end of the flexible elongate body. A fastener at one end of the connector is for releasably attaching the connector to a corresponding fastener of another connector. A receiver at the other end of the connector mounts the connector to the end of the flexible elongate body. A swivel means of the connector allows the fastener to rotate relative to the receiver.
In another embodiment of the invention, a connector for use with a flexible elongate closure means is provided. A receiver of the connector is for mounting onto an end of the flexible elongate closure means. A fastener of the connector, preferably opposite the receiver, is for releasably attaching the connector to a corresponding fastener of another connector located either on the other end of the flexible elongate closure means or on an end of another flexible elongate closure means. Optionally, a swivel means between the receiver and the fastener allows the fastener to rotate relative to the receiver.
In another embodiment of the invention, a coupler is provided which has a receiver for releasable attachment to an end of a flexible elongate closure means, such end having a conventional aglet. Preferably the receiver comprises a threaded cavity for screw-mounting onto the aglet. The other end of the coupler comprises a fastener for releasable attachment either to a corresponding fastener of a connector mounted on another flexible elongate closure means, or to a threading tool. In the former case, the coupler is able to be attached for example, to an end of a conventional drawstring or lace already within, e.g. a hoodie, thereby permitting an attachment in turn to a corresponding fastener of a connector mounted on another lace that is intended for replacement of the conventional lace. In the latter case, when the other end of the coupler is attached to a threading tool, such permits placement of the threading tool into a first end of a drawstring channel and then manual manipulation of the threading tool so as to move the threading tool, the coupler and the drawstring through the channel until the threading tool, coupler and the end of the drawstring attached to the coupler, exit the second end of the channel. In this manner a drawstring may be installed in such channel when no drawstring was in the channel beforehand.
In another embodiment of the invention there is provided the aforementioned flexible elongate closure means with connector, and the aforementioned connector, respectively wherein the fastener of the connector is also configured for releasable attachment to a finished end of a flexible elongate closure means for example, wherein said end of the latter means has a conventional finished aglet. Thus, such fastener can function for releasable attachment either to a corresponding fastener of another connector, or to an (e.g. aglet) end of a flexible elongate closure means, as may be preferred by the user. An advantage of such configuration of the fastener is that the connector concerned can also function as the aforementioned coupler, such that a coupler per se, as a separate item, would not been needed. Preferably, the fastener has a female receptacle configuration (such as a cavity) selectively, in the alternative, for releasable attachment to a male-configured fastener of another connector, and for releasable screw-attachment to a conventional finished end (e.g. aglet).
In using the latter embodiment, the invention also provides a method of replacing a first closure means of a product (e.g. a conventional drawstring with two finished ends, such as with aglets, that typically comes with the product) with a second closure means (e.g. a replacement drawstring) and then preparing to replace the second closure means with a third closure means (e.g. a second replacement drawstring). The first closure means comprises a flexible elongate body and at least one finished end. The first closure means is at least partially slidably positioned in an enclosure of the product. The second closure means comprises a flexible elongate body and a first connector. The first connector is positioned at one end of the flexible elongate body. The first connector comprises a fastener configured both for selective releasable attachment of the first connector to the at least one finished end of the first closure means and, in the alternative, for selective releasable attachment to a second connector positioned at one end of the third closure means. The third closure means comprises a flexible elongate body and the second connector. The method of using the foregoing comprises the steps of: attaching the fastener to the at least one finished end of the first closure means; pulling on the first closure means until the second closure means has replaced a position of the first closure means on the product; detaching the fastener from the at least one finished end of the first closure means; and attaching the fastener to the second connector in preparation for replacing the second closure means on the product with the third closure means.
In yet another embodiment of the invention a connector for use with at least one flexible elongate closure means is described. A first receiver mounts on a first end of a flexible elongate closure means. A second receiver mounts on a second end of the flexible elongate closure means or on an end of a second elongate closure means, where the first receiver is connectable to the second receiver by a coupling means such that the first receiver is opposite the second receiver when the first and second receivers are connected. Optionally, at least one a swivel means between the coupling means and the first and second allows the first and second receivers to rotate relative to the coupling means.
In another aspect of the invention, a method of replacing a first closure means of a product with a second closure means is described. A first end of the first closure means is connected to a first end of the second closure means. The first closure means is pulled until the second closure means has replaced a position of the first closure means on the product. The first closure means is unattached from the second closure means.
The present invention facilitates an easy removal and/or replacement of drawstrings from drawstring channels in the products that use them. For the present purposes, drawstring includes any flexible elongated closure means such laces, ties, strings, elastic cords, pull cords and other like product closure means. As best shown in
The receptor 18 is for mounting the connector 12 to an end of the flexible elongate body 3. In a preferred embodiment, the receptor includes a cavity of a diameter appropriate for receiving an aglet 9 of the flexible elongate body. This cavity may be 4 mm in depth, but other depths are possible as required. One of the aglets 9 is inserted into the cavity and glued or otherwise permanently fixed in place, thus bonding the connector 12 to the drawstring body 3.
The fasteners 20, 22 are each preferably one half of a barrel or torpedo clasp. Other types of fasteners are possible. The fastener is coupled to the receptor 18 and is for attaching to a complimentary fastener of another connector, either on the same drawstring or on a second drawstring. In a preferred embodiment, the fastener of a first end 14 of the drawstring 10 compliments the fastener of the second end 16 of the drawstring 10. For instance, the fastener of the first end 14 of the drawstring 10 may be configured as a female fastener 20 and the fastener of a second end 16 of the drawstring 10 may be configured as a male fastener 22.
The complimentary fasteners at first and second ends of the drawstring may be fastened together to lessen the movement of the portion of the drawstring that is outside the drawstring channel. Ribbing 5 on the circumference of the connector may be added to assist in gripping the connector.
Preferably, the receptor and fastener are manufactured as one unit and may be designed in many different shapes, sizes and materials. The connector may be made of metals or precious metals such as but not limited to gold, silver, bronze and copper plating, and may also be made of hard plastic, for example.
In a preferred embodiment, a swivel means is incorporated into the connector to allow the fastener to rotate in either direction relative to the receiver and the drawstring. Such rotatability of the fasteners facilitates easier connection by eliminating the need to turn the whole drawstring to fasten the connectors. The rotatability also lessens curling and twisting of the drawstring.
In one embodiment shown in
Ball bearings 32 may be further added to the swivel means at the rubbing surface between the swivel dial 30 and the base 26. This adds longevity to the swivel by lessening the amount of friction between the swivel and the base.
The connectors, with or without a swivel means, may be fastened to other similarly configured drawstrings. So for instance in
This invention thereby allows for easy replacement of drawstrings configured according to the invention that are present in products, as may be desired for reasons including wear, breakage or fashion statement. Different sizes, types, lengths and colours of drawstrings may be exchanged by this invention, so consumers will be able to accessorize and customize the products concerned as they see fit.
The invention is not limited to replacing drawstrings. In further accordance with the present invention, two or more drawstrings may be attached in series, end to end, using the connectors. This allows a user to connect drawstrings to vary the length of the overall drawstring and to combine different colours or styles of drawstrings. When worn on apparel having a drawstring and drawstring channel such as a hoodie, for instance, different styles of drawstrings could appear from each end of the drawstring channel, with the connector being hidden inside the channel. The fasteners are not limited to the preferred barrel or torpedo clasps mentioned above and shown in the drawings. Any type of fastener that is practical in nature and size for use on the first and second ends of a drawstring that has sufficient hold and can easily fit through a drawstring channel would suffice. For example, the fasteners may include magnetic, loop, snap, Velcro™ and latch forms of attachments.
The present invention also contemplates the more common situation where the drawstring in a product does not include the connectors described above, but is a conventional drawstring. A stand-alone connector, also referred to as a coupler 40, may be used to facilitate the replacement of a conventional drawstring with either another conventional drawstring, or a drawstring with the connector described above.
In an exemplary embodiment shown in
The coupler receiver may include a helical female receptacle means such as a threaded cavity for screwing onto the aglet 46. In a preferred embodiment, the threaded cavity is inwardly tapered (i.e. widest at the opening of the cavity, and tapers as it deepens) and has a depth of about 10 mm, though other depths are possible depending on the size of the aglets being considered. The tapered shape accommodates various sizes of aglets, and enables the aglet to be fastened securely to the receiving portion. The threading secures the coupler 40 to the aglet 46.
To further accommodate different sizes of aglets, differently sized couplers may be used. The table below presents suggested tapered cavity diameters of several sizes of couplers. These ranges accommodate most conventional aglets. It should be appreciated that the cavities may be made in other sizes if needed to accommodate aglets not within the ranges provided below.
The coupler fastener 44 may include a threaded male insert 50, configured to fasten to the threaded female connector 21 of the fastener 20 of a drawstring 10 of the present invention. The coupler fastener 44 is not limited to barrel-type screw fasteners, but may include magnetic, loop, snap, Velcro™ and latch forms of fasteners.
In a preferred embodiment, the threaded male insert 50 of coupler 40 in

Use of a coupler allows a user to attach a conventional drawstring to a drawstring of the present invention. The receiver or the coupler releasably attaches to an end of a conventional drawstring, typically in a drawstring channel of a product. A drawstring of the present invention is connected to the fastener of the coupler via the complimentary fasteners. Once linked, the conventional drawstring may be pulled through and entirely out of the drawstring channel, leading with the free end opposite the coupler. This simultaneously pulls the coupler and drawstring of the present invention. Once the drawstring of the present invention has replaced the conventional drawstring in the drawstring channel 4, the two drawstrings may be unfastened and the coupler removed. In this way, a conventional drawstring is replaced in the product by a drawstring of the present invention.
The present invention also contemplates the situation where both the drawstring in the product and the replacement drawstring are conventional drawstrings. A first coupler 40a may be connected via a coupling portion 47 to a second coupler 40b substantially opposite the first coupler 40a to provide a double-ended coupler 80. In one embodiment shown in
Use of a double-ended coupler allows a user to connect a first conventional drawstring to a second conventional drawstring by releasably attaching the receiver of the first coupler 42a to an end of the first drawstring, and releasably attaching the receiver of the second coupler 42b to an end of the second drawstring.
Where the first drawstring is secured in a product through a drawstring channel, after the aforementioned attachments have been made, the first drawstring may be pulled through and entirely out of the drawstring channel. In so doing, the double coupler and the second drawstring are simultaneously pulled into the channel. Since the double coupler passes through the channel, it should have a streamline profile so as to allow movement through the channel. Once the first drawstring is pulled out of the channel and the second drawstring has replaced it in the channel, the two drawstrings may be disconnected by unfastening the ends from the first and second couplers.
In an alternative embodiment shown in
In an exemplary embodiment, at least one of the first and second couplers can swivel relative to the coupling portion. Preferably, both the first and second couplers can swivel independently of each other about the coupling portion. In the embodiment shown in
To allow rotation of the second coupler 40b relative to the coupling portion, a second swivel arm 72b may be included which attaches to the second coupler 40b at a first end and extends through a second side 78 of the coupling portion 47 to a second swivel dial 74b at a second end. The coupling portion and/or the first and second couplers may include circumferential ribbing (not shown) to assist in gripping and rotating the double coupler for easier fastening.
In yet another preferred embodiment, the coupler of
In yet another embodiment there is provided a flexible elongate closure means with a connector, and also the connector per se, respectively wherein a fastener of the connector is configured both for releasable attachment selectively to a corresponding fastener of another connector (e.g. located on the other end of the flexible closure means), or to a conventional finished end (e.g. an aglet) of a flexible elongate closure means on a product (e.g. a drawstring that typically is included with a product when purchased). An advantage of such configuration of the fastener is that the connector concerned can also selectively function as the above discussed coupler (of the previously discussed embodiment), such that the coupler per se, as a separate item, would not be needed for purposes of replacing a conventional drawstring. Preferably, as shown in
