England-England (GB) 1187/73 (71) (72) Peter David Benmax, 2 Park Close, Ellesmere Road, Chiswick, London Wi *, England-England (GB) (74) Oy Kolster Ab (5 * +) Buttoning device This invention relates to a buttoning device comprising a combination of a button and a barbed member for penetrating a buttoned object, wherein the button or part thereof holds the barbed member and has a counter-member for receiving the barbed head of the barbed member, having a fastening wire or fastening member wrapped in a button or counter member.

It is well known per se in the field of buttoning that first the button must be provided with a thread and that this thread must then be connected to another button or similar binding part so that a cushion or buttoned object could be buttoned or deep-gripped depending on the length of this binding thread. The lice procedure is usually performed with a needle. However, improved buttoning methods are available and may use a button gun. Despite the use of this button gun, there is still a need to attach the fastening wire or the loop to the fastening parts, and it is this step that is uneconomical in terms of the time spent in the buttoning operation.

59325 It is an object of the present invention to provide a buttoning apparatus and a buttoning method in which the fastening of the fastening wire is carried out quickly and efficiently.

The present invention is characterized in that the barbed member is adapted to penetrate through the buttoned object without the use of a needle so that the fastening wire or fastening member disengages and secures the counter member and the button with the barbed member when the barbed head penetrates the counterpart or part thereof.

The term "coiled" is used in this specification to mean gathering or placing in such a way as to prevent entanglement.

The present invention can be more readily understood from the following description of the three exemplary cases shown in the accompanying drawings, in which: Figure 1 is a cross-sectional view of a button provided with a detachable barb or needle; Figure 2 is a side sectional view showing the button of Figure 1 thereafter. when it has been pierced and applied to or attached to a retaining member in the form of a second button, Fig. 3 is a side sectional view of a buttoning device in which the first button includes an integral barbed portion or needle therefor; the second button is provided with a detachable retaining member, Figures 4 and 4A show a button with an inspirable barbed part or needle held in place by fastening parts which are harness-shaped.

Referring now to Figure 1, there is a hollow button, generally indicated at 10 by the upper part 11 and the lower part 12, surrounding the hollow space 13. This lower body part 12 is provided with a centrally located opening 14 suitable for releasably holding and securing the barbed part 15. This barbed portion 15 has a sharp tip 15a, a stop portion or barb 15b and an end 15c remote from said sharp tip 15a, the latter end 15c being provided, if desired, with an eye not shown, which is then attached to the coil. an inserted fastening member in the form of a connecting thread 16 made of nylon or the like, this thread being integral with the barbed portion 15. This connecting wire 16 is knotted at 16a and placed on a spool of any suitable length inside the hollow space 13 in the button 10, depending on the depth of the object such as the bulge to be buttoned and the type of loose or deep buttoning to be applied to this product.

Referring now to Figure 2, the button 10 is now pushed and used to pass e.g. a pad 17 which is to be buttoned and a sharp tip 15a of the barbed portion 15 passes through the pad 17. The support portion 15b of this barb 15 engages a spring-loaded snap ring 18 formed by an opposite button and generally indicated by reference numeral 20. This barbed portion 15 is now detachable from the opening 14 using spring forces provided inside the pad when this pad reaches its final dimensions d1, and this dimension is determined by the length of the unwound fastening portion 16. The knot at 16a is unable to pass through the opening 14 and apparently the hub 17 is now buttoned by these two buttons 10 and 20, which are fastened to each other by a barbed part 15 and a connecting cord 16. As shown, the lice are a barbed portion 15 in one piece with the connecting cord 16, being made of nylon or the like.

As already indicated above, the button 10 consists of a body part 12 with an opening 14 which is inserted and held by a needle or barbed part 15. This barbed part 15 fits by pressing into the opening 14. The base part 12 has a spring edge 21 suitable for receiving the raised part 11 a button which, when in place (as shown), is secured sufficiently firmly to the base 12 to allow the barbed portion 15 to rest thereon as the barbed portion passes through the sling or similar portion to be buttoned.

Referring now to Figure 3, a button assembly 10 is formed therein according to Figure 1, wherein the needle 15 is integral with the button and is arranged to mate, after piercing the object to be buttoned, with the opposite button generally shown at 20. This barbed part 15 enters a collar 22 in the form of a collar held in place at the edge 23 by a base or base 24 in a button 20. This collar 22 is provided with a coiled device 25 in the form of a connecting wire provided with a knot at 26. Apparently when the needle enters the collar 21 it it is locked by it and the collar 22 is free to detach from the base 24, so that the buttoning is carried out in the same way as shown in Fig. 2.

Referring now to Figures 4 and 4A, a fastening member in the form of a coil fitted and unwound (or closed and expanded) harness array of nylon yarns, as shown. The barbed part 15 is mounted and provided with an end edge 15d which rests when the barbed part is detached from the button 10, a ring 27 attached to a harness group 28 of nylon strands attached at 29 to the base 12 of the button 10. The length of this unwound group Ä-2 can be made so that it is suitable for buttoning of any length, as shown, e.g. the distance d ^ according to Fig. 2.

Obviously, a button with its detachable needles or barbed parts and connecting threads, as shown in Figures 1 or 4, may be advantageous when using a matching button opposite, such as the button shown at 20 in Figure 3. In this way a long bond between these two by means of connecting cords 16 and 25 (or wire 16 and array 28) which are joined so as to obtain a large length at point d, j (Fig. 2) when the object to be buttoned is exceptionally thick.

The shape of the button used is not critical, provided, when necessary, that it has sufficient volume in itself to hold the fastening part wrapped around the coil. In general, this button is circular in shape and domed in cross section, but it may nm. be elliptical, rectangular or polygonal. Clearly, it can further be covered with any suitable surface material. The retaining member is generally a button or the bottom of a button, but as such may be a needle or a barbed part per se, as this needle may have been provided with an extended support part 15b (Figure 1).

Alternatively, the needle may be provided with pivoting barbs similar to those used in a harpoon, with these barbs remaining closed during piercing of the bullet or button object and the barbs opening after piercing to act as retaining members.

The button and / or their retaining members shown in Figures 1, 2, 3 or 4 can be connected to a single rectilinear structure so that they can be easily fed for use from a magazine to a button station or a button-fed pistol.
