This application is entitled to, and claims, a benefit of a right of priority under 35 U.S.C. § 119 from United Kingdom patent application 1616804.9, filed on 3 Oct. 2016, the content of which is incorporated by reference as if fully recited herein.
The present invention pertains generally to a hook and eye fastener for securing two pieces of a garment together. More specifically, the present invention relates to a hook and eye fastener particularly suited for securing two pieces of a brassiere together.
Three of the main considerations when designing a fastener for a brassiere are strength, ease-of-use, and profile. The fastener must be sufficiently strong that it can withstand applied tensile forces, it must be easy for the user to manipulate, particularly if the fastener is located at the rear of the brassiere, and it preferably will have a low profile so that it is not highly visible through over-garments.
One such fastener that satisfies many of these criteria is described in the applicant's own co-pending UK Patent Application No. GB1507925.4 (UK Patent Application Publication No. GB2538109). The fastener described therein is particularly easy to manipulate, even by those with manual dexterity problems, and has a relatively low profile so that it is practically invisible under most over-garments. However, there is one shortcoming of the fastener described in GB1507925.4 in that when constructed with a low profile, the fastener is typically only able to withstand tensile forces of the order of 15 lbs to 20 lbs (6.80 kgs to 9.07 kgs). Although still useful, this limitation constrains the potential applications of the fastener.
For example, such a fastener is not particularly suited to sports brassieres (commonly referred to as “sports bras”) or to brassieres of larger sizes, as these garments are typically subjected to higher tensile forces. Increased applied force could result in the brassiere inadvertently opening, leading to inconvenience, discomfort and/or embarrassment of the wearer.
It is an object of the present invention to provide a fastener that addresses at least some of the above-identified problems. It is a further object of the present invention to provide a fastener that is strong, easy to use, and that has a relatively low profile. It is a further still object of the present invention to provide a fastener for a garment that offers a useful choice to the consumer.
A hook and eye fastener is provided for securing two pieces of a garment together, the hook part configured to be mounted on a face of one of the pieces and the eye part configured to be mounted on a face of the other of the pieces, in which:
By having such a fastener, the fastener will be simple to use and will have a relatively low profile resulting in the fastener being practically invisible under most garments. Perhaps more importantly, the fastener will be strong and will be able to withstand tensile forces on the order of 25 lbs to 30 lbs (11.34 kgs to 13.61 kgs), an increase in strength on the order of between 25%-100% on the closest existing offering. This increased strength greatly increases the number of potential applications for the fastener. For example, the fastener will be suitable for sports bras and for brassieres produced for women with larger breast sizes.
In one embodiment of the hook and eye fastener the slot and the divider wall are off-center with respect to the leading edge of the lip and the outer portion of the arm, respectively.
In one embodiment of the hook and eye fastener there are provided a pair of spaced-apart slots formed in the lip along a leading edge thereof and a pair of spaced-apart divider walls located on the underside of the arm each divider wall arranged and configured for engagement in one of the slots formed in the lip.
In one embodiment of the hook and eye fastener the pair of spaced-apart slots are spaced evenly about either side of the center of the leading edge of the lip and the pair of spaced-apart divider walls are spaced evenly about either side of the center of the outer portion of the arm. In this way, the loads will be spread more evenly across the fastener and the hook part will be less inclined to distort and consequently permit inadvertent release of the fastener under an applied force.
In one embodiment of the hook and eye fastener there is provided at least one rib formed along a rear surface of the inner portion of the arm. By providing at least one rib, and preferably a plurality of ribs, on the rear surface of the inner portion of the arm, the arm will have even less tendency to distort under an applied force. This will enable the fastener to be manufactured relatively thin without decreasing the strength of the fastener to the point where it is ineffective for many applications.
In one embodiment of the hook and eye fastener the rib extends upwardly from the substantially planar body along the rear surface of the inner portion of the arm.
In one embodiment of the hook and eye fastener there are provided a plurality of ribs spaced apart from each other along the rear surface of the inner portion of the arm.
In one embodiment of the hook and eye fastener the eye part further comprises an upstanding flange adjacent the eye part abutment surface. The flange will effectively act as a backstop for the outer portion of the hook part and this will facilitate location of the hook part in the eye part. This feature is particularly useful when the fastener is located to the rear of the garment.
In one embodiment of the hook and eye fastener there are provided a plurality of eye parts mounted in a row along the piece of garment. This will provide good adjustability to the garment allowing for variation in body shapes and sizes.
In one embodiment of the hook and eye fastener the piece of the garment where the eye part is mounted comprises a pair of sheets of fabric and the eye part is sandwiched between the pair of sheets of fabric. This is seen as a particularly simple construction yet it will obviate the possibility of the fastener causing irritation to the wearer.
In one embodiment of the hook and eye fastener the one of the pair of sheets of fabric sandwiching the eye part that lies substantially above the eye part is welded to the eye part with ripples in the sheet of fabric. By welding the sheet to the eye part with ripples (i.e. by leading the sheet back over on itself in places) in the sheet of fabric, the engagement of the eye part with the sheet has been found to be more robust and capable of withstanding higher forces.
In one embodiment of a hook and eye fastener the eye part is constructed from polyamide 6.6. Alternatively, the hook and eye fastener may be constructed from polyamide 6. Polyamide 6.6 in combination with the rippled welding is seen as particularly effective for those application that require strength such as sports bras and bikinis whereas polyamide 6 is seen as more suitable for those applications that require a more refined, smoother finish such as lingerie.
In one embodiment of a hook and eye fastener a pocket is formed between the abutment surface on the underside of the frame of the eye part and the face of the piece on which it is mounted.
In one embodiment of the hook and eye fastener there is provided a boss on one of the hook part abutment surface and the eye part abutment surface and a dimple shaped complementary to the boss on the other of the hook part abutment surface and the eye part abutment surface. The boss and dimple will co-operate with each other to more securely fasten the hook part and eye part together and prevent inadvertent release of the fastener. These are relatively simple to manufacture as they can be molded into the hook and eye components.
In one embodiment of the hook and eye fastener the boss is mounted on the hook part abutment surface.
In one embodiment of the hook and eye fastener the boss and the complementary dimple are located substantially centrally relative to the leading edge of the lip and the outer portion of the arm.
In one embodiment of the hook and eye fastener the outer portion is chevron shaped. This is seen as a useful embodiment of the present invention as the chevron shape will help guide the hook into a central location in the eye, ensuring correct alignment and engagement of the hook and eye.
In one embodiment of a hook and eye fastener the eye part abutment surface on the underside of the frame for engagement of the hook part abutment surface is chevron-shaped. This will also promote correct location of the hook part in the eye part and will help to create a secure engagement therebetween.
In one embodiment of the hook and eye fastener the hook part and eye part each comprise a complementary magnet for location of the hook part outer portion in the open mouth of the eye part. Magnets are advantageous as they will further simplify the engagement of the hook and eye into the finder position thereby simplifying the closure of the fastener. This feature is particularly helpful when the fastener is located at the rear of the garment behind the wearer's back.
In one embodiment of the hook and eye fastener the magnet on the hook part is located on the body rearward of the arm and the magnet on the eye part is located in the frame rearward and remote from the abutment surface. By placing the magnets in these areas, the depth dimensions of the hook and eye can be kept relatively thin to ensure that the overall thickness of the fastener is not increased.
In one embodiment of the hook and eye fastener at least one of the pieces is elasticated.
In one embodiment of the hook and eye fastener there is provided only one hook. This is advantageous as it will facilitate the closure of the fastener about the wearer. This is made possible in part by the structural integrity of the configuration of hook.
In one embodiment of a hook and eye fastener at least one of the pieces is provided with padding. Preferably, if padding is provided, the piece having the eye parts will be padded as this will enable the padding to be spread across the back of the wearer (if the fastener is positioned to the rear of the wearer). Padding is particularly advantageous in sports bra applications.
Further provided is a garment including a hook and eye fastener substantially as described herein.
Other embodiments, in addition to the embodiments enumerated above, will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the fastener and method of use.

Importantly, the hook part 5 comprises a pair of divider walls 41, 43 located on the underside of the arm for engagement in the slots 17, 19 formed in the lip 15 of the eye part 3. The divider walls 41, 43 extend downwardly and substantially perpendicular from the hook part abutment surface 37 of the outer portion 35 of the arm 31 and forwardly and substantially perpendicular from a front surface 45 of the inner portion 33 of the arm 31. In addition to the divider walls 41, 43, there are provided a plurality of ribs 47 on the rear surface 49 of the inner portion 33 extending upwardly from the body 29 along the inner portion 33 towards the outer portion 35. In combination, the divider walls 41, 43 and the ribs 47 provide greater structural rigidity to the hook part 5. In this way, the hook part is capable of withstanding higher tensile forces applied thereto and the hook part will not have a tendency to bend out of shape and inadvertently release from the eye part 3. Furthermore, the manner in which the divider walls 41, 43 engage the slots 17, 19 also provides greater strength to the fastener 1 and obviates the likelihood of the hook part 5 becoming inadvertently dislodged from the eye part 3.

Once in the finding position of
Release of the eye part 3 from the hook part 5 may be effected by overcoming the applied tensile force and the force of the boss 39 in the dimple 25 by pulling the hook part in the direction of arrow B and by simultaneously sliding the eye part in the direction of arrow A and then moving the two pieces away from each other.
It will be appreciated that in order to get into the finding position illustrated in

In the embodiment shown in
In the embodiments shown, there are two divider walls 41, 43 and five ribs 47 on the hook part 5 along with two slots 17, 19 on the eye part 3. Furthermore, there is a single boss 39 on the hook part 5 and a single dimple 25 on the eye part 3. These are not limiting unless otherwise specified in the claims, and it will be understood that more or fewer divider walls and corresponding slots may be provided, more or fewer ribs may be provided, and more or fewer bosses and dimples may be provided, if desired. Furthermore, the positioning of the divider wall(s), the slot(s), the rib(s), the boss(es) and the dimple(s) may be varied, if desired, and unless otherwise stipulated by the claims.
It will be seen from the foregoing examples, that the hook and eye fasteners according to the embodiments shown have only a single hook as opposed to a plurality of hooks as is common in the known fasteners. This is seen as a highly advantageous aspect of the present invention. Generally speaking, the hook and eye fasteners known in the art comprise a column of two or more hooks and several columns of two or more corresponding eyes, depending on the width of the back of the garment. In some cases, five or more hooks aligned in a vertical column may be provided. Such hooks have to be closed one at a time, which is difficult and cumbersome for the wearer, and it is often difficult to align the hooks correctly with the corresponding eyes. As a consequence, the hooks and eyes are often misaligned or the hooks and eyes have to be located first into the outermost position before the hooks are thereafter adjusted and inserted into the desired correctly fitting position. The overall thickness of the hook and eye fastener shown is of the order of 5 mm (0.005 m) or less. In the embodiment shown in
Further provided is a garment including a hook and eye fastener as described herein.
The embodiments of the fastener and garment described herein are exemplary and numerous modifications, combinations, variations, and rearrangements can be readily envisioned to achieve an equivalent result, all of which are intended to be embraced within the scope of the appended claims. Further, nothing in the above-provided discussions of the fastener and garment should be construed as limiting the invention to a particular embodiment or combination of embodiments. The scope of the invention is defined by the appended claims.
