    Description

    BACKGROUND OF THE INVENTION



    [0001] The present invention relates to a removable button or snap-fastener construction.

    [0002] As is known, in a garment article comprising high quality button or snap-fastener assemblies, the latter must be removed before washing the garment article, to prevent them from being damaged by cleansing and solvent substances and mechanical washing and ironing operations.

    [0003] After having washed and ironed the garment article, said buttons or snap fasteners must be obviously relocated on the garment article.

    [0004] The removal and, mainly, the re-application of the snap fasteners are fatiguing operations which require a comparatively long time.

    [0005] A button construction of the prior art is disclosed in US 5.115.548.

    SUMMARY OF THE INVENTION



    [0006] The aim of the present invention is to provide such a button construction which may be quickly and easily removed and reassembled again on the garment or cloth article.

    [0007] Within the scope of the above aim, a main object of the invention is to provide such a removable button construction which has good aesthetical features.

    [0008] Another object of the present invention is to provide such a button construction which, owing to its specifically designed structural features, is very reliable and safe in operation.

    [0009] According to one aspect of the present invention, the above mentioned aim and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by a removable button construction, characterized in that said construction comprises a fixed body which may be associated with a fabric material flap and being adapted to support a removable portion including a button element associated with a decorated portion; said fixed body comprising a stem including a nail element; said fixed body being clamped to the fabric flap or portion by said nail element passing through said flap and being swaged or clamped in any other suitable manner in a counter-portion arranged on the opposite face of the fabric.

    [0010] The counter-portion comprises preferably a disc element including a hole having a tapering section and which is engaged by a tip of said nail element, said tip being swaged or counter-riveted in said hole.

    [0011] The stem comprises a threaded seat adapted to be engaged by a threaded end piece of said button element, thereby allowing said button element, together with its decorated portion, to be removably associated with said fixed body.

    BRIEF DESCRIPTION OF THE DRAWINGS



    [0012] Further characteristics and advantages of the present invention will become more apparent hereinafter from the following disclosure of a preferred, though not exclusive, embodiment of the invention, which is illustrated, by way of an indicative, but not limitative, example in the accompanying drawings, where:

    Figure 1 is a longitudinally cross-sectioned view of the removable button construction associated with a fabric flap;

    Figure 2 is a further longitudinally cross-sectioned elevation view of the button element associated with the decorated portion;

    Figure 3 is yet another longitudinally cross-section elevation view of the nail stem;

    Figure 4 is yet another longitudinally cross-section elevation view of a cap counter-part;

    Figure 5 yet another longitudinally cross-section elevation view of a simple counter-portion;

    Figure 6 is yet another longitudinally cross-section elevation view of a swaged counter-portion;

    Figure 7 is yet another longitudinally cross-section elevation view of a further embodiment of the removable button construction according to the invention associated with a fabric flap;
    and

    Figure 8 is yet another longitudinally cross-section view of the nail stem associated with the construction shown in figure 7.


    DESCRIPTION OF THE PREFERRED EMBODIMENTS



    [0013] With reference to the number references of the above mentioned figures, the removable button or snap-fastener construction according to the present invention, which has been generally indicated by the reference number 1, comprises a fixed body 2 which may be coupled to a fabric flap 3 and being adapted to support a removable portion including a button element 4, associated with a decorated portion 5.

    [0014] Said fixed body 2 comprises a stem 6 including a nail element 7.

    [0015] Said stem 6 comprises a threaded seat 8 which may be engaged by a threaded end-piece 9 of the button element 4.

    [0016] Thus, the button element 4, together with its decorated portion 5, may be removably associated with said fixed body 2.

    [0017] The fixed body 2, in turn, is clamped to the fabric flap 3 by the nail 7 passing through said flap and being swaged or clamped in any other desired manner, in a counter-portion 10 including a disc element having a tapering cross-section hole 11.

    [0018] Said counter-portion 10 may also comprise a cap element 12, as shown in figure 4.

    [0019] According to a further embodiment of the invention, the counter-portion, which in figure 6 has been indicated by the reference number 11, is swaged.

    [0020] Figure 7 shows yet another embodiment of the removable button or snap-fastener construction 1 according to the present invention, in which the fixed body, generally indicated by the reference number 22, comprises a stem 6 including a nail element 7 and a flange or base 13.

    [0021] The base 13 comprises, on a side thereof facing the fabric flap 3, a annular ridge or projection 14.

    [0022] The decorated portion 5, in turn, comprises a central opening having a bottom edge 15 and adapted to engage the head portion 16 of the button element 4.

    [0023] Said decorated portion 5 is locked on the head 16 of the button element 4, but swaging the bottom edge 15 on said head or by a glue layer applied between the perimetrical outer edge of the button element head 16 and the inner portion of the bottom edge 15 of the decorated portion 5 opening.

    [0024] Alternately, said decorated portion 5 may be connected to the head 16 of the button element 4 by a welding operation.

    [0025] According to the present invention, the button element 4 and decorated portion 5 integral therewith may be removed from the fixed body 2 while leaving the latter associated with the fabric 3, by simply screwing off the button element.

    [0026] Then, the button element 4 may be re-screwed again on the fixed body 2.

    [0027] It has been found that the invention fully achieves the intended aim and objects.

    [0028] In fact, the invention has provided a removable button or snap-fastener construction allowing to easily and quickly remove and reassembling again the decorated portion while leaving its base or bottom firmly anchored to the garment or cloth article.

    [0029] The removable button construction according to the present invention provides moreover the advantage of having a thin thickness owing to the fact that the nail element 7 is swaged or clamped to the opposite side of the stem 6, thereby the stem threaded seat 8 may be fully engaged by the threaded end-piece 9 of the button element 4.

    [0030] Thus, the axial dimension of the construction, that is the distance x between the surface of the fabric 3 and the decorated portion 5 laying plane, will be very small.

    [0031] Yet another advantage is that the tip end of the nail element 7 is swaged at the opposite side of the stem 6 and that the swaging operation must not be performed within the threaded seat 8 of the stem, thereby preventing said seat or stem from being damaged.

    [0032] The height dimension of the button construction is very small, since the swaged tip end of the nail element 7 and counter-portions 9, 11 and 13 have a small or thin thickness.

    [0033] In practicing the invention, the used materials, as well as the contingent size and shapes, can be any, depending on requirements.
