A third aspect of the invention provides a construction comprising first and second web like substrates, said second substrate including a hole, and a fastener as defined hereinabove attached to said first substrate, said hole and/or said fastener being so sized that the fastener can pass through the hole in its release condition and cannot pass through the hole in its retaining condition, the fastener and the hole being, in use, in opposed relation whereby the fasten can pass through the hole to join the first substrate to the second substrate.
In a preferred such construction the first and/or second substrates comprise woven or non-woven fabrics.
The invention also relates to a garment including a construction according to the third aspect of the invention.
For a better understanding of the invention and to show how the same may be carried into effect reference will be made, by way of example only, to the following drawings in which: Figure 1 is a side plan view of a fastener according to the invention; Figure 2 is a longitudinal cross section through the fastener of Figure 1; Figure 3 is an underneath plan view of the fastener of Figure 1; Figure 4 is a view similar to Figure 1 showing the retaining and release conditions of the fastener; Figures 5A and 5B illustrate in top plan views alternative constructions for the fastener according to the invention; Figure 6 is a top plan view of a fastener according to a variation of the invention; Figure 7 is a side view of the fastener of Figure 6; Figure 8 is a perspective view of a fastener according to the second aspect of the invention; Figure 9 is a longitudinal cross section through the fastener of Figure 8; Figure 10 shows constructional detail of one fastener according to the first aspect of the invention; and Figures 1 la to 1 to illustrate the use of a fastener according to the invention in joining parts of a garment, such as a jacket.
Referring now to Figures 1 to 7 and 10, the fastener 10 comprises a fastening portion 12 and a base portion 14. In figures 1 and 2 the fastener 10 is shown in its securing condition and the fastening portion 12 defines the maximum lateral dimension of the fastener at dimension B-B. The fastening portion 12 comprises a lower (as illustrated, but not necessarily as in use) retaining section 16 and an upper (as illustrated but not necessarily as in use) projecting section 18 which extends away from the retaining section 16 and the base portion 14.
The base portion 14 is formed from a relatively rigid material such as a high impact polystyrene, polypropylene, ABS, polycarbonate, PET (polyethyleneterephthalate) or a suitable metal and is permanently attached to first substrate 20 by suitable means such as stitching 22. The base portion 14 and the fastening portion 12 are permanently, or at least firmly, attached to each other so that they cannot be separated in normal use. A suitable arrangement is illustrated in Figure 2 where the base portion 14 includes a pillar 24 with an enlarged head portion 26. The enlarged head portion 26 engages a lower part of the fastening portion 12 in a latching manner.
In one preferred construction, the fastening portion 12 comprises upper and lower component parts 12a, 12b which have mating surfaces 28a, 28b joined together by suitable means such as by ultrasonic welding. The upper and lower parts 12a, 12b and the base portion 14 may be made by any suitable means, such as injection moulding.
In use of the fastener, the base portion 14 is first attached to the first substrate 20.
The first substrate 20 may be a web of woven or non-woven fabric such as may, for example, be a part of a garment, a bag or suitcase or the like. The fabric may alternatively be part of a covering material for apparatus such as a pram, pushchair or the like. The fabric may be of a natural fibre such as cotton, or a synthetic fibre, or a mixture and may alternatively be of a natural material such as leather or of a synthetic leather-look material. The first substrate may alternatively, in some uses, be a generally rigid material such as a metal or plastic frame element of apparatus such as a pram, pushchair or the like on which the base portion 14 may be directly mounted.
The fastening portion 12 may be mounted on the base portion before or after the base portion 14 is secured to the first substrate 20.
The second substrate 28 includes a hole 30 in the manner of a buttonhole sized to effectively co-operate with the fastener, as will be described below. The second substrate 28 may be a woven or non-woven fabric, as for the first substrate 20.
In order join the first substrate 20 to the second substrate 28, the hole 30 in the second substrate 28 is brought into proximity to the fastener 10. The fastener 10 (specifically the fastening portion 12) is then deformed such as by squeezing with the fingers at B-B or by pulling projecting section 18 (Figs 1 la, 1 lb) so that its lateral dimension is reduced (see the ghost lines in Figure 4). The longitudinal dimension (along axis A-A) will normally be correspondingly increased. This deformation allows the fastening portion 12 to pass through the hole 30 (Fig 1 lb), after which the fastening portion may be released. Projecting part 18 assists in providing an area of the fastening portion 12 which is easily gripped by the user's fingers. The fastening portion then returns resiliently to its initial configuration (Fig l lo) where its lateral dimension is maximum, in which configuration it is unable to pass through the hole 30, since its lateral dimension is sized to be greater than the size of the hole. Thus, the second substrate 28 is attached by the fastener 10 to the first substrate 20. In order to release the second substrate 28 from the first substrate 20, the fastening portion 12 is squeezed at B-B allowing it to pass back through the hole 30 so that the first substrate 20 can be separated from the second substrate 28.
Figures SA and 5B illustrate alternative configurations ofthe fastening portion 12 in which the fastening portion 12 comprises a plurality of laterally extending arms 12c spaced circumferentially apart form one another.
Figures 6 and 7 illustrate a variation of the invention in which the separate base portion 14 is not used, the fastener 10' being formed with an integral base part 32 which is attached in use to the first substrate 20, such as by stitching.
Figures 8 and 9 illustrate a fastener according to the second aspect of the invention in which the fastening portion 34 is non-resilient, or has limited resilience. In this embodiment the fastening portion 34 comprises upper and lower parts 34a, 34b joined by one or more live hinges 36. The live hinges 36 allow the fastening portion to be deformed between the retaining condition in which the lateral dimension of the fastening portion 34 is maximum and the release condition in which the lateral dimension is minimum by squeezing the fastening portion along BB-BB. Biasing means are provided to urge the fastening portion towards the retaining condition. In the illustrated embodiment the biasing means are elastic threads 38 which are anchored at one extremity to the first substrate 20 and which are attached at their other extremity to a part 40 of the fastening portion 34 which is distal from the first substrate. Thus the elastic threads act to draw the part 40 towards the first substrate 20.
