DETAILED DESCRIPTION OF THE DRAWINGS
(20) Referring to
(21) The front element 200 comprises a third catch face 211 and a fourth catch face 213. The third catch face 211 is directed substantially perpendicular to the one end 207 of the front element 200 and is directed away from one side 215 of the front element. The third catch face 211 is angled such that the front edge of the third catch face is closer to the side 215 of the front element than the back edge of the third catch face 211. The fourth catch face 213 is also directed substantially perpendicular to the one end 207 of the front element 200 but is directed towards the one side 215 of the front element so that the front edge of the fourth catch face is further from the side 215 of the front element 200 than the back edge of the fourth catch face 213. At least portion of the third and fourth catch faces is directed substantially perpendicular to the one end 207 of the front element however other portion of the third and fourth catch faces may be directed at an angle substantially less than perpendicular to the one end 207 of the front element 200.
(22) The seat cavities 201 each comprise an annular rim 217 defining an open mouth of the seat cavity. There is further provided a channel 219 formed in the annular rim 217 for reception of a complementary column (not shown) of the back element 300, as will be described in greater detail below.
(23) Referring now specifically to
(24) The back element 300 further comprises a third complementary catch face 311 for engagement with the third catch face 211 and a fourth complementary catch face 313 for engagement with the fourth catch face 213. The third complementary catch face 311 is directed substantially perpendicular to the one end 307 of the back element 300 and is directed away from one side 315 of the back element. The third complementary catch face 311 is angled such that the front edge of the third complementary catch face is further from the side 315 of the back element than the back edge of the third complementary catch face 311. The fourth complementary catch face 313 is also directed substantially perpendicular to the one end 307 of the back element 300 but is directed towards the one side 315 of the back element 300 so that the front edge of the fourth complementary catch face is closer to the side 315 of the back element 300 than the back edge of the fourth complementary catch face 313.
(25) As will be understood from the following description, the pair of catch faces 303, 305 are operable to resist a force in the direction of arrow A in
(26) The bumps 301 each comprise a column 317 for engagement in the channel 219 of the front element. The columns 317 effectively provide one of the pair of catch faces 303 and join the third complementary catch face 311 and the fourth complementary catch face 313 together. When the column 317 is engaged in the channel 219, this will reduce the likelihood of the bump twisting in the cavity seat and becoming dislodged therefrom.
(27) Referring to
(28) The fabric tab 209 of the front element 200 comprises a pair of strips of fabric 221, 223. The strips of fabric are connected together at a point 225 spaced apart from their free ends 227, 229 to allow a piece (not shown) to be engaged between the free ends 227, 229 of the strips of fabric. The other ends 231, 233 of the strips are connected together and at least part of the seat cavity is sandwiched between the strips of fabric 221, 223 intermediate the other ends 231, 233 and the point 225. The front element 200 has a magnet 235 housed in a casing 237 forward of the seat cavity. The magnet is retained in the casing by the strip of fabric 221 and a seal 239 above the strip of fabric 221. The seal 239 also forms the base of the seat cavity.
(29) The back element 300 has a fabric tab 309 that also comprises a pair of strips of fabric 319, 321. However, in this instance, the strips 319, 321 are not connected directly together but instead are connected to a base 323 upon which the bumps 301 are mounted. The base 323 is partially sandwiched between the pair of strips 319, 321. The free ends 325, 327 of the strips 319, 321 are spaced apart from each other to allow the other piece (not shown) to be engaged between the free ends 325, 327 of the strips 319, 321. A magnet 329 is housed in the bump 301 and is retained in the bump by a seal 331 and the strip 319. The magnets 235 and 329 are polarised to attract each other thereby facilitating location of the bump 301 in the seat cavity 201.

(37) It will be understood that while the efficacy of the catch face 303 against the normal wearing force will be reduced in this configuration, resistance against the normal wearing force will nevertheless be provided by the catch faces 303, 305 and also by parts of catch faces 311 and 313. Resistance to forces in the direction opposite to the normal wearing force will be provided by the catch face 601 and resistance to forces in directions perpendicular to the normal wearing force will be provided by catch faces 311 and 313.

(42) These stages of engagement dearly illustrate the security of the fastener when it is under no tension and when it is under normal wearing tension. In order to release the fastener, the back element is moved against the force of the normal wearing tension from the configuration shown in
(43) Finally, referring to
(44) In the examples shown, there are typically two bumps and two seat cavities provided on each of the fasteners. However, this is not intended to be limiting and is for illustrative purposes only. For example, it is envisaged that a single bump could be provided with a single seat cavity. Alternatively, a single bump may be provided with a plurality of seat cavities arranged along the length of the strips 221, 223 to provide a degree of adjustability to the fastener. Finally, a plurality of bumps, i.e. more than two, and a plurality of seat cavities could be provided if desired depending on the resistance to the release force required. Furthermore, it is envisaged that there may be a different number of cavities to bumps. For example, it is envisaged that there may be more cavities than bumps to allow the bump to be located in a different cavity thereby providing a degree of adjustability to the fastener.
(45) As outlined above, throughout this specification the fasteners are described as being used between the back wings of a brassiere, and the terms front and back are used in that context (i.e. the front portion is that portion forwardmost on the wearer when the fastener is in use and the rear portion is that portion rearmost on the wearer when the fastener is in use). The invention however is not limited to such use or orientation and would also work well if reversed or applied to another application. For example, the present invention could be used as a front closure of a brassiere in which case the terms front and back would typically be reversed as that part of the fastener with the cavities would normally be located adjacent the body of the wearer and that portion of the fastener with the bumps would ordinarily be located on the far side of the part of the fastener with the cavities (i.e. the part with the bumps would be the part most remote from the wearer's body). Similarly, the fastener according to the invention could be used as a side fastener for a brassiere or instead of buttons or as an auxiliary fastener such as next to a zip on an item of clothing or piece of luggage.
(46) In the embodiments described, reference is made to third, fourth and fifth catch faces however it will be understood that this is merely to identify the different catch faces and distinguish them from the other catch faces. For reasons of clarity, simply because reference or claim is made to a fifth catch face, this does not necessarily imply that there is a third and/or a fourth catch face and indeed there may only be the first, second and fifth catch faces in that circumstance unless otherwise specified.
(47) In this specification the terms comprise, comprises, comprised and comprising and the terms Include, includes, included and including are all deemed totally interchangeable and should be afforded the widest possible interpretation.
(48) The invention is in no way limited to the embodiments hereinbefore described but may be varied in both construction and detail within the scope of the appended claims.
