DESCRIPTION:
BRIEF SUMMARY
The present invention relates to fastening buttons in a time saving and more permanent manner. This is especially useful for rapid fastening of buttons which have fallen off a garment.
People often feel that it is uphill work to be obliged to fetch a needle and thread to fasten a button which has fallen off a garment. To many persons the task of threading a needle is quite impracticable. This especially concerns weak-sighted persons as well as old people. Consequently, many garments stay untouched in the closets, or are even thrown away, because they lack buttons and the task of fastening them appears to be too cumbersome and time consuming.
It is an object of the present invention to simplify this task and render it more efficient, and to provide a method of fastening buttons and an apparatus for such an application, which will solve the above problems.
This object is achieved by the method and the apparatus which are characterized by the features stated in the claims.
It is known that buttons may be fastened to a substrate by the aid of rigid threads, e.g. pins, plastic threads, or the like. The new concept of this invention is that the button is fastened by a flexible and, at the same time, rigid thread, so that said thread will remain at a certain distance from the substrate to permit the textile fabric portion with the button hole to be readily buttoned and then to move freely about the button.
This invention is essentially different from other known techniques in that all four attachment threads for buttons are collected into a thin bundle on the underside of the button before the fastening threads pass through the fabric, so that a larger area of the button contributes to hold it in the button hole. The button hole will consequently enclose the collected fastening threads or pin of the button more tightly and closer to the centre of the button. This will result in a reduced hazard of the button slipping out of the button hole again; the buttoned state is, thus, more stable. At the same time there will be less wear of the button hole.
The fastening thread, which may be a plastic covered or finished metal thread or the like, may preferably be designed to be adapted to the holes which are present in standard buttons. This invention, thus, does not require use of special buttons, but may be used for standard buttons on the market. Furthermore, the fastening means is at the end designed to pass readily through the textile fabric, both down through the fabric and up through the fabric upon being curved in the bottom of the device.
By using the invention, it will be possible to fasten the button by the aid of various suitable means, both in a manual and in an automatic manner.
The invention also relates to an apparatus for fastening the button onto the substrate, which differs essentially from any other known technique by fastening the button rapidly to the substrate without use of a needle, a sewing thread, or any kind of loose pieces to be attached on the underside.
It is also an advantageous feature that the apparatus for fastening the button on the substrate is designed in such a manner that it may be held and used by hand. In this connection it is especially useful for fastening buttons which fell off after the garment had been used for some time. The invention represents an essential novelty considering the time spent for fastening a button by other known methods.
The invention is disclosed below with reference to the drawing, in which the fastening method and an apparatus for use with said method are illustrated. In the drawing:
FIG. 1 shows the fastening thread 1 designed with four legs pointing downwards;
FIG. 2 shows the fastening thread 1 when threaded in place through the holes of a button 2;
FIG. 3 shows button 2 with fastening thread 1 provided in holder means 3 of the apparatus, with the clamping means of the apparatus in an open state;
FIG. 4 shows clamping means (4) in a clamped state due to the fact that the cover of the apparatus is closed, and that the legs of fastening thread 1 are cla
