1 Claim. (Cl. 24-90) ABSTRACT OF THE DISCLOSURE In combination a button having a shank either forming a part of or separate from the button, the shank having a point for piercing the fabric and adapted to'be sectioned after insertion and a retainer for fitting round the shank for securing the button to the fabric lying between the retainer member and the button.
Already known are rapidly secured buttons the placing of which requires various operations in order to fasten them to a fabric and immobilize them thereon. These operations, more or less protracted, and therefore costly, do not make it possible for such buttons to be substituted advantageously for the conventional buttons which are maintained by a thread.
The present invention proposes to eliminate these disadvantages in a simple and effective manner.
According to the present invention, the shank of the button, in plastic material, integral with the button or retained thereto by any means, is made, either smooth, and its retaining member against the inner surface of the fabric is constituted by a clip, such as for example those employed in body work, or notched, by circular grooves or notches in which can be force-fitted, a keeper ring or the like. Advantageously, the shank of the button is sectioned, after assembly, as close as possible to its retaining members, clip, keeper ring, etc. in order to eli minate its pointed end, which permits its introduction through the fabric.
Advantageously the shank of the button has on the side of the button a relatively large head glued on the rear surface or in a suitable housing in the button, which permits moreover the use of all buttons and in particula those with holes.
Similarly, in order to obtain a relatively rigid linkage between the button and its shank, the bore of said button and the shoulder of the shank engaging in said bore, have peripheral, circular or helical grooves and the like, either interpenetrating when these grooves or the like are made on the button and on its shanks, or penetrating, by force-fitting of the shank in the bore of the button, in a housing or behind a circular lip of either the button or of the shank which does not have this or these grooves.
The invention will be furthermore better understood by reference to the following description and to the accompanying schematic drawing giving, by way of non-limiting example, preferred embodiments of the invention.
FIGURE 1 is a cross-sectional longitudinal view of the button according to the invention secured on a fabric.
FIGURES 2, 3, 4 and 5 are sectional or longitudinal cross-sectional views of buttons made according to modifications of the invention.
FIGURES 6 and 7 are front elevational views of retaining clips intended to be mounted on the shank of the button shown on FIGURE 5.
FIGURES 8 and 9 are longitudinal cross-sectional views of other modifications of the button according to the invention.
In FIGURE 1, a plastic shank 1 having a conical part 2 and ensuring the retention of button 3 is introduced 3,389,439 Patented June 25, 1968 by means of its pointed end 6, through a fabric 7. This shank has circular grooves 9 permitting, after assembly, its immobilizing by means of a keeper ring or the like 8 engaged in said grooves. Shank 1 is then cut off behind keeper ring 8, for example, along plane 10.
In FIGURE 2, a shank 13 comprising, as shank 1 of FIGURE 1, grooves 9 for positioning the keeper ring, is not mounted on button 12 but is an integral part thereof.
In FIGURE 3, shank 16 has a cylindrical head 17 engaging in a housing 18 around the bore 19 of button 20. Furthermore, shank 16 is provided with a small collar 21 which, during mounting, becomes crushed and blocks itself in said bore 19, thus ensuring the rigidity of the assembly between the button and said shank.
In FIGURE 4, shank 26 is provided with a fiat head 28 making possible the linking thereof with button 27 by gluing on the rear face 29 of the button. Besides, nicks 30 are provided in said shank 26 along transverse planes according to one of which is force-fitted the keeper ring, the clip or the similar retaining member. 1
In FIGURE 5, a shank 37 comprises a truncated head 36 on the peripheral face of which are made longitudinal grooves 38 interpenetrating with other grooves provided in bore 39, also truncated, of button 40.
There is thus obtained the immobilization, at least rotationally, of the shank on the button. Besides, the shank 37, made with a completely smooth surface, is retained after assembly by a lock washer or clip 41, of a type analogous to that used in body building.
In FIGURE 6, a rectangular clip 41 has two legs 43 while clip 42 of FIGURE 7, which is circular, has three legs 43. Owing to the rearward folding of said legs 43, clips 41 and 42 can be easily introduced on the shank of the button of FIGURE 5, while their withdrawal cannot be effected, the legs 43 planting themselves in and propping themselves against said shank.
In FIGURE 8, the head 43 of a shank 49 is provided with circular grooves 50 corresponding to those, 51, with which is provided bore 52 of button 53 and making possible, by force fitting, the rigid linking of shank 49 on said button. Besides, the retention on the fabric of button 53 is obtained by a clip, such as 41, mounted on said shank 49.
In FIGURE 9, the linkage of shank 58 with button 59 is obtained by means of a convex spherical part 57 of head 56 of said shank, said head being introduced with slight pressure in the spherical concave housing 59 of button 60, introduction facilitated by a chamfer 61. As in FIGURES 5 and 8, the button is secured by a clip.
Moreover, in FIGURES 2, 3, 4, 5, 8 and 9, the shank of the button is cut off after assembly, as described in FIGURE 1, as close as possible to the retaining member, but preserving the groove, if any, of the housing of said member.
The scope of the invention will not be avoided regardless of the shapes, the dimensions, the proportions and the appearance of the button, of the shank and/or of the retaining means. Furthermore, these different constituent elements of the button can be obtained in any suitable material or combination of materials, and may undergo all suitable physical, chemical and mechanical treatments, etc. and can be mounted in any suitable way on all fabrics, articles of clothing or the like without departing thereby from the framework of the invention.
What is claimed is:
1. In combination with a button, a shank having one end secured to said button and having a point at the other end thereof for piercing a fabric having an inner surface to which said button is to be fastened, said point being adapted for sectioning off after mounting of said button on said fabric, and a retainer member fitting around said shank against said inner surface of said fabric, said button having a central counter-sunk housing and said shank having therearound a small tapered collar of crushably deformable material adapted for force-fitting in the reduced portion of said housing for rigidly securing said shank to said button.
