1. Technical Field of the Invention
The present invention generally relates to a fastening system, and, more particularly, to a lace fastening assembly and method for using same for facilitating simple, efficient and secure fastening of an article.
2. Description of Related Art
Fastening or tightening objects by means of strings or laces is known. Typically, a string or lace is run through a series of holes on opposing sides of an article to be secured together, and the free ends of the string or lace are then pulled to bring the opposing sides together.
In particular, many types of footwear employ lacing to secure footwear onto the foot. While alternate fastening means exist, such as fabric hook and loop fasteners, zippers, etc., tying with laces is often superior for a number of reasons. For example, the use of laces provides the user with many more degrees of adjustment in the fit of an article, enabling the user to create as snug or loose a fit as desired. Namely, as the material of the footwear itself is worn over time it becomes broken in, causing a looser fit, which the user can compensate for by tying the laces tighter. In other instances, the user's foot may swell slightly during the course of the day, and the user may accordingly loosen the laces a desired amount to accommodate the swelling. A true custom fit is thus achieved each time the footwear is worn.
Another advantage with using laces as a fastening system in footwear is that it typically provides greater strength than zippers or hook and loop fasteners, both of which are prone to breakage and failure, especially during vigorous athletic activities which impose high tensile forces upon a footwear's fastening means.
However, conventional lacing systems have some disadvantages over other fastening means. For example, tying laces is typically more time consuming than using, e.g., a zipper, and also involves a degree of skill and manual dexterity to create a proper knot of sufficient tightness and end loop lengths to ensure the knot will not be too easily untied.
In the case of footwear, laces also add bulk to the top of a shoe, especially due to the knot and/or free end portions of the lace. This can be especially disadvantageous in certain sports, such as soccer, where footwear which has a low profile kicking surface is essential.
Furthermore, laces often nevertheless become untied, sometimes repeatedly, especially when the user engages in athletic activity, particularly in youth sports. In footwear, this creates a hazardous situation for the user by increasing the risk of tripping, thus requiring the user to stop, bend down and retie the lace before being able to return to the activity.
During, e.g., a team sport activity, this can be disruptive not only to the user but to the players, coaches and spectators, particularly in youth sports where children require adults to tie their laces. Repeated instances of laces becoming untied by multiple players can seriously interrupt the overall flow of a game.
While extra knots could be employed to prevent a lace from become untied during use, this is often undesirable as it increases the difficulty and time in both securing and releasing the article, as well as adds additional bulk, e.g., to the top of a shoe.
Accordingly, a need exists for an easy-to-use fastening system which securely fastens an article while adding minimal bulk, and which is easy to fasten and unfasten by the user.
The present invention generally relates to fastening systems, and more particularly, to a fastening assembly which provides secure lace fastening, quick unfastening and is easy to use. A fastening system according to the present invention may be utilized for any article in which releasable tightening and fastening via laces is desired. Non-limiting examples include various articles of clothing such as pants, tops and undergarments; bags and other accessories, therapeutic garments and footwear.
In particular, a fastening assembly according to the present invention is advantageously used for securely fastening footwear to a user's foot while adding minimal bulk to the footwear, especially to the top surface of the footwear, and is easy to fasten and unfasten by the user. For illustrative purposes only, and not by way of limitation, a fastening device and method will be shown herein with respect to footwear.
The present invention enhances safety and functionality by providing a simplified fastening system that is easily used even by those with physical limitations and which eliminates the possibility of untied laces. Advantageously, the customized adjustment and support provided by laces is preserved while ease of use is improved.

Each slack portion is pulled through a set of holes in the opposing edges of the article to form at least one lace loop. Each lace loop is overlapped over the fastener body.
According to yet another aspect, a method for fastening an article is provided including the steps of providing an article having holes in opposing edges of an article opening and a lace passed through said holes. At least one fastener body is provided having an attachment point, wherein the lace is secured to the attachment point, forming at least one slack portion. Each slack portion is pulled through a set of holes in the opposing edges of the article to form lace loop(s). Each lace loop is overlapped over the at least one fastener body.
These and other aspects, features, and advantages of the present invention will be described or become apparent from the following detailed description of the preferred embodiments, which is to be read in connection with the accompanying drawings.
In the drawings, wherein like reference numerals denote similar elements throughout the views:
It should be understood that the drawings are for purposes of illustrating the concepts of the invention and are not necessarily the only possible configurations for illustrating the invention.
A fastener assembly in accordance with an aspect of the present invention, advantageously enables an article (which may include holes/eyelets) that employs laces to be fastened or tightened securely in an efficient manner, while minimizing added bulk to the article and providing inimitable ease of use for the user. Especially when used with respect to, e.g., apparel or footwear, a fastener assembly according to an aspect of the present invention promotes safety and comfort for the user by preventing untied laces and avoiding added bulk next to the body, while enhancing aesthetic appeal and providing a neat, streamlined appearance.
An exemplary fastener assembly 100 according to one embodiment of the present invention is illustrated in and will now be described with respect to the various views of
A top portion of the body 101 preferably includes a cavity 301 into which a cap 103 may be received.
The fastener body according to the invention may be in the shape of a disc (as shown in the drawings for exemplary purposes, but not by way of limitation), but may be formed in any shape, e.g., the body 101 may be cylindrical, conical, spherical, or any other two or three-dimensional form and/or irregular, symmetrical and/or asymmetrical shape including dog bones, star shapes, prisms, etc. Preferably, the shape of the body 101 is flattened laterally, so as to provide an overall streamlined appearance, low profile and reduce bulk.
The fastener body and cap of the present invention may be comprised in whole or in part of any substantially rigid material, including but not limited to plastic, polymers, resins, metal and metal alloys, glass, bone, shells, wood, and the like and any combination or composite thereof, and further, may include coatings or coverings comprised of, e.g., lacquered/adhesive finishes and coverings, silicon, rubber and the like. The fastener body and cap of the present invention are preferably shaped and sized to be easily manipulated by hand, but may be provided in a range of sizes and shapes without departing from the scope or spirit of the present invention.
The laces used in the present invention may comprise any suitable material for cordage including but not limited to cotton, nylon and other synthetic fibers or natural/synthetic blends, and further, may preferably be elastic by, e.g., incorporating elastic fibers therein to impart elastic/resilient properties at least along a portion of the length of the lace and/or the entire lace in a longitudinal/lateral direction.
As shown in
The cavity 301 may be of any shape and is preferably at least of a size and depth sufficient to contain the enlarged ends 305. In one exemplary embodiment, the cavity 301 may include a rim 701 and the cap 103 may include correspondingly shaped ridges/edges 703 to mate with the rim 701 and thus improve secure fitting of the cap 103 within the body 101.
The cap 103 is preferably formed of a size, depth and shape corresponding to the cavity 301 so as to be configured to be removably inserted within and seal the cavity. When fitted within the cavity 301, the cap 103 is preferably flush and/or follows a similarly contoured shape with a top surface of the body 101.
According to the embodiment shown in
For example, the fastener body 101 includes curved ends 401, 403 and a concave bottom surface (shown e.g., in
This is particularly advantageous in a footwear application, in that the fastener assembly 100 is advantageously configured to conform to the top surface of a shoe to closely follow and ‘hug’ the surface of the user's instep, and provide an overall lower profile and minimize bulk on the shoe. Furthermore, the curved ends 401, 403 of the fastener body 101 improve secure fastening and holding of lace loops 107, 109 thereon, as described further below.
According to one exemplary aspect, a fastener body according to the present invention preferably includes an attachment point which may comprise at least two apertures, with each aperture proximate to each opposing end of the fastener body. For example, when the fastener body is substantially disc-shaped as shown, the apertures are preferably located opposite from each other, on opposite ends of the disc.
However, it may be contemplated that the fastener body as described herein may include as an attachment point only a single aperture or any number of apertures arranged in any configuration. Furthermore, in lieu of or in addition to apertures formed within the fastener body, the attachment point of the fastener body may comprise any means for attachment of a lace, such as external attachment points including protrusions formed on or attached to the fastener body which themselves may include an aperture, and the like.
For example, the fastener body may comprise a single aperture through which at least one free lace end is inserted and secured (e.g., as shown in
A lace may be secured to the fastener body via knots, enlarged ends, end caps, or simply being run through the fastener body or through an external attachment point on the fastener body.
Furthermore, an additional aperture(s) 307 in the fastener body may be provided which preferably communicates with the cavity to facilitate, e.g., easier removal of the cap by inserting a tool through the additional aperture(s) 307 upwards into the cavity, thus pushing out the cap.
The fastened configuration of the assembly 100 as shown in
When it is desired for the fastener assembly 100 to fasten (close/tighten) the article opening, each lace end 105, 106 is pulled (preferably through eyelets of the article desired to be fastened) so that a certain amount of slack in the lace is created, thus forming an adjacent portion of each lace end into an independent loop (e.g., loops 107 and 109). Each independent loop 107 and 109 is then pulled over the body 101 preferably in succession so as to overlap one another, thus taking up and effectively securing the slack in the lace.
An exemplary fastener assembly 800 according to another embodiment of the present invention is shown in
A cap 803 may be provided which is shaped to be removably insertable into a cavity 802 of the fastener body 801. Lace ends 807, 808 are inserted into apertures 804 and secured to the fastener body 801 via e.g., enlarged ends 805. Lace loops 809, 811 are overlapped over the fastener body 801 to achieve the fastened configuration shown.
An exemplary fastener assembly 1200 according to another embodiment of the present invention is shown in
In one exemplary aspect, the arms 1205 are attached, for example, substantially in a center of the inner surface of the housing 1202 and are preferably angled downwards (i.e., away from an attached cap 1203) with respect to the housing 1202, so as to protrude into the hole 1204 at a non-perpendicular angle.
Each of the arms 1205 further preferably includes at least one aperture 1207.
The arms 1205 substantially separate the hole 1204 into an upper cavity 1217 and a lower cavity 1219. The upper cavity 1217 is further defined by the upper portion of the housing 1202 and is preferably configured for removable insertion of a cap 1203 therein. The upper portion of the housing 1202 may include various features for securing the cap 1203 once it is inserted, including, but not limited to, tapered walls, clips, protrusions and ridges. For example, protrusions 1223 are shown in
Lace ends 1212 are inserted into apertures 1207 and secured to the fastener body 1201 via e.g., knots 1209. Lace loops 1211, 1213 are overlapped over the fastener body 1201 to achieve the fastened configuration shown.
According to an advantageous aspect of this embodiment, a bottom of the housing 1202 includes at least one, preferably two ridges 1215 within the lower cavity 1219. The ridges 1215 are formed and defined with respect to the angulation of the arms 1205 as described above, and facilitate grabbing and securing of the lace loops 1211, 1213 when the lace loops are in a fastened configuration.
Advantageously, the angulation of the arms 1205 in the downwards direction causes the arms to protrude into the lower cavity 1219 and causes the angle between the ridges 1215 and the arms 1205 to be smaller relative to the angle between the arms 1205 and the side walls 1221 of the upper cavity 1217. This downwards angulation of the arms 1205 improves the secure fastening of the lace loops and prevents their slippage once secured.
It is to be noted that the fastener assembly 1200 of this embodiment may alternately be comprised of a fastener body having curved ends (e.g., as shown in
An exemplary fastener assembly 1600 according to another embodiment of the present invention is shown in
Lace ends 1607 are inserted through apertures 1604 and through cord locks 1603. The cord locks 1603 are inserted within the apertures 1604, which further compresses and clamps the lace ends, thus firmly securing the lace end within the fastener body 1605. A cap 1601 may be provided for insertion into the top of the fastener body 1605, and lace loops 1609 are overlapped over the fastener body 1605 to achieve the fastened configuration shown.
In step 2101, a lace having a first end and a second end is secured to opposing edges of an article opening which is desired to be closed/fastened. For example, the lace may be passed through holes/openings provided along/adjacent to the opposing edges of the article.
Alternate means and methods for securing the lace to the article may be contemplated. For example, the lace may be at least partially permanently secured to the article. Preferably, the lace is slidably secured to the edges of the article opening, such that it can be pulled freely through the openings to facilitate the actions of tightening and loosening the lace, thus expanding and contracting the size of the article opening.
In a preferred embodiment, the lace is secured to the article in an interwoven manner, weaving back and forth between the holes on either side of the article opening. Preferably however, the lace is run laterally through at least two pairs of holes/openings adjacent to the free ends 1901, so that each portion 1902 of the lace is caused to run substantially parallel to each other (i.e., provides at least two parallel lace portions), as shown in
In the exemplary depiction shown in
In step 2103, each lace end 1901 is secured to the fastener body 2001 (e.g., by inserting into at least one aperture 2003 of a fastener body 2001). Each lace end may be secured to the fastener body 2001 via enlarged ends, e.g., knots 2005, protrusions and/or enlargements, end caps, cord locks and the like formed/placed at the lace ends.
In optional step 2104, the lace ends, once secured, are preferably trimmed to reduce excess bulk, and/or a cap 2007 may optionally be inserted into the fastener body.
Preferably, each lace end 1901 is secured to the fastener body 2001 so that at least one slack portion 1903 preferably of at least about 1½ inches, and most preferably, about 2-3 inches in length remains. It is noted that according to one exemplary embodiment in which there are two lace ends, once the lace ends are secured to the fastener body 2001, the lace itself essentially forms a continuous loop (e.g., as shown in
In step 2105, each slack portion 1903 is taken up by pulling the lace in the article, for example, at portion 1902 (e.g., a location proximate to a pair of holes/eyelets at each side of the article opening, where the lace ends are run substantially parallel to each other) thus forming at least one lace loop 1905. Each lace loop 1905 is pulled over the fastener body 2001 in an overlapping fashion (step 2107) to form the fastened configuration shown in
In step 2205, each slack portion 1903 is taken up by pulling the lace through a pair of holes at each side of the article opening, thus forming at least one lace loop 1905. Each lace loop 1905 is pulled over the fastener body 2001 in an overlapping fashion to form the fastened configuration (step 2207).
