BACKGROUND OF THE INVENTION
1. Technical Field
This invention relates to an eye fastener, in particular such a fastener suitable for forming an eye connector for use (but not exclusively) in garments items.
2. Related Art
Many garment items, in particular lingerie (including brassieres), include connectors having hook and eye fasteners for providing flexible but firm coupling. In general, an array of hook fasteners (in rows and columns) is sewn onto a first tape, and a complementary array of eye fasteners is sewn into a second tape, and by engaging different hook fasteners and eye fasteners, a degree of lengthwise adjustment is allowed.
In such conventional hook and eye fasteners, both the eye fasteners and hook fasteners are typically formed of a stiff metal wire. The eye fasteners are generally C-shaped with two free ends sewn and received within the tape to form an opening, in which the plane defined by the opening of each eye fastener lies against the tape. It is found that when a user seeks to engage the eye fastener with a hook fastener, one has to slightly pivot the eye fastener away from the tape to further expose the plane of opening, to facilitate engagement with the hook fastener. This is relatively difficult, in particular in the case of brassieres, where the hook and eye fasteners are at the back of the user.
It is thus an object of the present invention to provide an eye fastener and a tape including at least one such eye fastener in which the above shortcoming is mitigated, or at least to provide a useful alternative to the trade and public.
SUMMARY OF THE INVENTION
According to a first aspect of the present invention, there is provided an eye fastener including a base defining a base plane, and at least an eye extending from the base and defining a plane of opening, characterized in that the plane of opening is displaced relative to the base plane.
According to a second aspect of the present invention, there is provided a tape including at least one eye fastener, the eye fastener including a base defining a base plane, and at least an eye extending from the base and defining a plane of opening, characterized in that the plane of opening is displaced relative to the base plane.

DESCRIPTION OF PREFERRED EMBODIMENTS
An eye fastener according to a first embodiment of the present invention is shown in FIGS. 1 to 4, and generally designated as 100. The eye fastener 100 is formed integrally of a wire (such as a metal wire), e.g. by bending. The eye fastener 100 has two anchor portions 102 (each being a free end of the eye fastener 100), two parallel leg portions 104 each extending from a respective of the anchor portions 102, and a generally C-shaped portion 106 joining, extending from and bent relative to the two leg portions 104.
The anchor portions 102 form a base, defining a base plane P-P, on which the leg portions 104 also lie. The C-shaped portion 106, which extends from the base, forms an opening (“eye”) through which a hook fastener may be releasably engaged. It can be seen from FIG. 3 that the plane Q-Q defined by the C-shaped portion 106 (“plane of opening”) is displaced relative to the plane P-P defined by the anchor portions 102 and leg portions 104 (“base plane”), and the two planes P-P, Q-Q are joined via bent portions 120. Although the angle a between the plane of opening Q-Q and the base plane P-P is shown in FIG. 3 as being an obtuse angle, such may alternatively be a right angle or an acute angle. The distance d between the uppermost end of the C-shaped portion 106 and the leg portions 104 (and the anchor portions 102) is from 0.5 mm to 5 mm.
As shown in FIG. 5, to produce a tape with an array of eye fasteners 100, a first row of eye fasteners 100 are assembled between a backing sheet 108 and a first layer of padding material 110. In particular, the first row of eye fasteners 100 are arranged along a straight line, with their anchor portions 102 fixed (e.g. by sewing) between the backing sheet 108 and the first layer of padding material 110, and with their leg portions 104 and C-shaped portions 106 exposed to the outside environment.
As shown in FIG. 6, a second row of eye fasteners 100 are assembled between the backing sheet 108 and a second layer of padding material 112. In particular, the second row of eye fasteners 100 are arranged along a straight line which is parallel to the straight line along which the first row of eyes 100 are arranged. Again, the anchor portions 102 of the second row of eye fasteners 100 are fixed between the backing sheet 108 and the second layer of padding material 112. The leg portions 104 and C-shaped portions 106 of the second row of eye fasteners 100 are also exposed to the outside environment.
Finally, as shown in FIG. 7, a third row of eye fasteners 100 are assembled between the backing sheet 108 and a third layer of padding material 114. In particular, the third row of eye fasteners 100 are arranged along a straight line which is parallel to the straight lines along which the first and second rows of eye fasteners 100 are arranged. Again, the anchor portions 102 of the third row of eye fasteners 100 are fixed between the backing sheet 108 and the third layer of padding material 114. The leg portions 104 and C-shaped portions 106 of the third row of eye fasteners 100 are also exposed to the outside environment.
A tape 116 with three rows of eye fasteners 100 fixed thereto is thus formed. There is of course no definite restriction on the number of rows of eye fasteners 100 which may be carried by the tape 116. A manufacturer may decide on the number of rows of eye fasteners 100 for the tape 116 according to the use to which eye connectors formed from the tape 116 are to be put.
As shown in FIG. 8, the plane of the backing sheet 108 is parallel to the base plane P-P of the eye fasteners 100, and is displaced relative to the plane of opening Q-Q of the eye fasteners 100.
Turning to FIG. 9, it can be seen that eye connectors 118 each with an array of two-by-three eye fasteners 100 are formed from the tape 116. Such eye connectors 118 may be formed by cutting the continuous tape 116 transversely by a cutter vibrated ultrasonically at intervals. The eye connectors 118 so formed may then be sewn onto semi-finished brassieres for forming final products.
An eye fastener according to a second embodiment of the present invention is shown in FIGS. 10 to 13, and generally designated as 200. The eye fastener 200 is formed integrally of a wire (such as a metal wire), e.g. by bending. In particular, the eye fastener 200 has two anchor portions 202 (each being a free end of the eye fastener 200), two parallel leg portions 204 extending from and bent relative to the anchor portions 202, and a generally C-shaped portion 206 joining, extending from and bent relative to the two leg portions 204.
The anchor portions 202 form a base, defining a base plane R-R. The leg portions 204 and the C-shaped portion collectively form an opening (“eye”) through which a hook fastener may be releasably engaged. The leg portions 204 define a first plane S-S and the C-shaped portion 206 defines a second plane T-T. The first plane S-S and the second plane T-T collectively form a plane of opening. It can be seen from FIG. 12 that the plane S-S defined by the leg portions 204 (i.e. the first plane) is displaced relative to the base plane R-R, and the plane T-T defined by the C-shaped portion 206 (i.e. the second plane) is displaced relative to the first plane S-S and is parallel to the base plane R-R. The base plane R-R and the first plane S-S are joined with each other via first bent portions 220a; and the first plane S-S and the second plane T-T are joined with each other via second bent portions 220b. Although the angle β between the first plane S-S and the base plane R-R is shown in FIG. 12 as being an obtuse angle, such may alternatively be a right angle or an acute angle. The distance e between the uppermost end of the C-shaped portion 206 and the anchor portions 202 is from 0.5 mm to 5 mm.
As shown in FIG. 14, to produce a tape with an array of eye fasteners 200, a first row of eye fasteners 200 are assembled between a backing sheet 208 and a first layer of padding material 210. In particular, the first row of eye fasteners 200 are arranged along a straight line, with their anchor portions 202 fixed (e.g. by sewing) between the backing sheet 208 and the first layer of padding material 210, and with their leg portions 204 and C-shaped portions 206 exposed to the outside environment.
As shown in FIG. 15, a second row of eye fasteners 200 are assembled between the backing sheet 208 and a second layer of padding material 212. In particular, the second row of eye fasteners 200 are arranged along a straight line which is parallel to the straight line along which the first row of eyes 200 are arranged. Again, the anchor portions 202 of the second row of eye fasteners 200 are fixed between the backing sheet 208 and the second layer of padding material 212. The leg portions 204 and C-shaped portions 206 of the second row of eye fasteners 200 are also exposed to the outside environment.
Finally, as shown in FIG. 16, a third row of eye fasteners 200 are assembled between the backing sheet 208 and a third layer of padding material 214. In particular, the third row of eye fasteners 200 are arranged along a straight line which is parallel to the straight lines along which the first and second rows of eye fasteners 200 are arranged. Again, the anchor portions 202 of the third row of eye fasteners 200 are fixed between the backing sheet 208 and the third layer of padding material 214. The leg portions 204 and C-shaped portions 206 of the third row of eye fasteners 200 are also exposed to the outside environment.
A tape 216 with three rows of eye fasteners 200 fixed thereto is thus formed. It should of course be understood that a manufacturer may decide on the number of rows of eye fasteners 200 for the tape 216 according to the use to which eye connectors formed from the tape 216 are to be put.
As shown in FIG. 17, the plane of the backing sheet 208 is:
- parallel to the base plane R-R of each eye fastener 200,
- displaced relative to the first plane S-S of the plane of opening as defined by the leg portions 204 of each eye fastener 200, and
- parallel to the second plane T-T of the plane of opening as defined by the C-shaped portion 206 of each eye fastener 200.
Turning to FIG. 18, it can be seen that eye connectors 218 each with an array of two-by-three eye fasteners 200 are formed from the tape 216. Such eye connectors 218 may be formed by cutting the continuous tape 216 transversely by a cutter vibrated ultrasonically at intervals. The eye connectors 218 so formed may then be sewn onto semi-finished brassieres for forming final products.
It can be seen from the foregoing discussion and the accompanying drawings that as the plane of opening of the respective eye fasteners 100, 200 according to this invention is displaced relative to the respective base plane P-P, R-R (which lie against the respective backing sheet 108, 208), such allows easy engagement between eye connectors 118, 218 and complementary hook connectors.
It should be understood that the above only illustrates examples whereby the present invention may be carried out, and that various modifications and/or alterations may be made thereto without departing from the spirit of the invention.
It should also be understood that certain features of the invention, which are, for clarity, described in the context of separate embodiments, may be provided in combination in a single embodiment. Conversely, various features of the invention which are, for brevity, described in the context of a single embodiment, may also be provided separately or in any appropriate sub-combinations.
