Abstract
A plate element has extending from one major surface thereof a filament portion; it is provided with two passages extending between the two major surfaces, and on the major surface remote from the filament portion with an open groove extending between the two passages at right angles to the elongation thereof. The filament portion is pushed through a web and from the remote side of the web pushed through again, thus forming at the side of the web remote from the plate a loop in which a button or the like may be engaged. The filament is then pushed successively through the two passages in the plate forming at the side of the plate which is remote from the carrier web a loop through which the free end portion of the filament is then pulled so that it is located in the groove. Instead of the plate, the filament portion may also be provided on the bottom or on a section of a snap fastener which can thus be connected with a carrier web without sewing.

Striker [57] ABSTRACT A plate element has extending from one major surface thereof a filament portion; it is provided with two passages extending between the two major surfaces, and on the major surface remote from the filament portion with an open groove extending between the two passages at right angles to the elongation thereof. The fil ament portion is pushed through a web and from the remote side of the web pushed through again, thus forming at the side of the web remote from the plate a loop in which a button or the like may be engaged. The filament is then pushed successively through the two passages in the plate forming at the side of the plate which is remote from the carrier web a loop through which the free end portion of the filament is then pulled so that it is located in the groove. Instead of the plate, the filament portion may also be provided on the bottom or on a section of a snap fastener which can thus be connected with a carrier web without sewmg.

7 Claims, 10 Drawing Figures l ATTACHING OF BUTTONS AND THE LIKE WITHOUT SEWING BACKGROUND OF THE INVENTION The present invention relates generally to the'securing of buttons, snap fasteners and the like to a carrier without sewing, and more particularly to a securing element for effecting such securing and to buttons, snap fasteners or the like which can be so secured.

It is already known from the art to secure buttons and similar components to carriers, such as garments and the like, by providing the button with a filamentary shank which is passed through the garment and provided with an eye or the like through which a retaining member is extended. This prior-art proposal is disadvantageous insofar as a button connected in this manner to a garment or the like will be rather loosely retained, which is frequently found objectionable or even functionally disadvantageous. Moreover, there is always the danger that the retaining element might slip out of the eye and might thus become disconnected and lost.

According to another proposal of the prior art a plate member is utilized through which the filamentary shank of the button is passed in an appropriate opening of the plate member, to be retained and connected in this opening with an adhesive. Insofar as this proposal is concerned, thedisadvantages are to be seen in the fact that it is not only necessary to utilize additional adhesive in addition to the other components, but also that the application of the adhesive requires a further operating step and that it is necessary to wait a certain period of time before the button can be used in order to give the adhesive a chance to set.

Still another proposal of the prior art provides for a button having a filamentary shank with a wavy end portion. This end portion, pushed through the garment is inserted into a plate-like or other retaining member having a channel provided with constricted portions in which the wavy end portion of the filamentary shank is supposed to become clampingly engaged. Experience has shown that in this construction the retentive capability is inadequate and that buttons so secured tend to get lost. The same applies to still another proposal in which a button is utilized with an undercut annular groove and with a filamentary shank which is passed from one side through the garment to the other side and back to the one side whereupon inserted into the annular groove and after several windings are taken therein, allowed with the free end of the filamentary shank to abut against the inner wall bounding the groove. This construction, also tends to become disengaged.

SUMMARY OF THE INVENTION It is, accordingly, a general object of the present invention to provide an improved solution to the problem of securing a button or the like to a carrier web without sewing.

More particularly, it is an object of the present invention to provide an improved securing element for securing such a button or the like to a carrier web without sewing.

It is also an object of the invention to provide an improved button, snap fastener or the like which can be secured to a carrier web in this manner, that is without sewing.

Still another object of the invention is to provide such a securing element, button or snap fastener which, when connected in this manner with a carrier web, is retained reliably against undesired and unintended disengagement.

In pursuance of the above objects, and of others which will become apparent hereafter, one feature of the invention resides in a securing element for securing buttons and analogous closure members to a carrier web. Broadly stated this securing element comprises a plate portion and at least two filament guide portions which are provided on the plate portion and are elongated in respective intersecting planes. A filament portion extends from the plate portion and has a first section adjacent the same, a second section remote from theplate portion and provided with a tip for penetrating a carrier web, and a third section intermediate and connecting the first and second section. In use, the filament portion is made to penetrate with its tip through a carrier web from one to the other side thereof and is then connected in suitable manner with a button, snap fastener or analogous closure element, for instance by passing through a lopp-shaped shank of the closure element. Thereupon the tip of the filament portion is passed through the carrier web again through the first side and is then made to pass through one of the guide portions so that its first section becomes located therein under formation of a loop constituted by the third section. The second section is then made to pass through this loop and to enter in and be retained in the other of the guide portions.

When a securing element connected in this manner is subjected to pull, that is when pull is exerted upon the filament portion, then the loop formed by the third section of the filament will pull against the second section thereof which it overlies and which is more remote from the source where pull is exerted, (namely the button or other closure member secured by the securing element) than the third section, and the greater the pull the more reliable the second section will be retained in its other guide portion against release. In addition, the fact that the sections of the filament portion cross one another, the tensile forces which act upon the individual sections of the filament portion when pull is exerted, will decrease stepwise from the source of pull towards the second section which is retained by the loop constituted by the third section. It is thus impossible for such pull to overcome the friction with which the loop constituting the third section forces the second section to remain in its associated guide portion, and a highly reliable securing of a closure member connected with the securing element is therefore achieved.

The securing element according to the present invention can be used, as already indicated above, for securing various types of closure members, to a carrier, such as a garment. This includes buttons, portions of snap fasteners and the like and it will be appreciated that it is entirely within the scope of the invention to pass the filament portion repeatedly through the carrier from one side to the other that is more than twice if it is necessary or desirable to have it extend through av given number of thread openings provided, for instance in a button.

On the other hand, it is within the scope and intent of the invention that a button, a section of a snap fastener or the like can itself be constituted in a manner mentioned above with respect to the securing element.

In this case, the button, snap fastener section or the like (whether it be male or female) is then provided with the filament portion and with the filament guide portions. The filament portion of such a button or the like can cooperate with a plate member located at the side of the carrier remote from the button, that is it can be passed through one or more holes in such a plate portion, but in the simplest approach the filament portion will simply be passed through the garment or the like from the side where the button is located to the other side, and back to the side where the button is located to be engaged in the filament guide portions of the button. It goes without saying, that in this embodiment, as in the one utilizing a separate securing element, any excessive length of the filament portion that is any length of the filament portion which extends in undesirable manner out of and beyond the other guide portion, can be cut off or otherwise suitably removed.

It is advantageous that the other guide portion mentioned above, in which the second section beomes located and straddled by the loop formed by the third section, be configurated as an open groove on the side ofthe securing element, the button or the snap fastener section which in use will be exposed, that is will face away from the carrier. The groove can be formed in the exposed surface or it can be a recess located between projecting ridges which most advantageously are located in the region of opposite margins of the plate portion or the like, spaced from the point where the second section is crossed by the loop formed by the third section. The formation of a groove recessed in the exposed surface is, however, particularly advantageous because in this manner the second section can be completely recessed beneath the plane of this exposed surface, aside from the fact that it greatly facilitates insertion of the second section.

The other guide portion through which the first section of the filament portion passes, is advantageously in the form of a pair of transversely spaced passages formed in the plate portion or analogous element (such as button, snap fastener section or the like) which extend from one to the other major surface of the plate portion or the like and through which the first section of the filament portion is passed in sequence. It is advantageous if these passages are located at opposite lateral sides of the aforementioned groove and it is further preferable that the groove extend normal to an imaginary line connecting the two passages with one another. This results in a particularly effective clamping action of the loop with respect to the second section of the filament portion.

The clamping action is further enhanced and is particularly effective, if the second section is engaged and straddled as closely as possible by the loop formed by the third section, which can be achieved in a simple manner by spacing the passages from one another by a distance which corresponds relatively closely to the diameter of the second section, and which should be as close as possible to this diameter.

The passages themselves may be either in form of actual openings extending through the plate portion inwardly of the margin thereof, or they may be in form of notches or kerfs provided in the marginal circumferential portion of the plate portion. Notches of course permit a particularly simple insertion of the filament portion. In order to permit location of not only the second section but also the third section entirely below the plane of the major surface in which the aforementioned groove is formed, it is advantageous to connect the passages by a transverse groove so that there is no longer any portion of the filament extending beyond the exposed surface. The effective depression of the groove in which the second portion of the filament is located, should be smaller with reference to the outermost point of the loop formed by the third section, then the diameter of the filament portion in the region where the loop formed by the third section straddles the second section, at most it should be equal to the diameter of the filament portion.

In effect it might be said that the manner in which the filament portion cooperates with the plate portion, or

in lieu of the plate portion with a button or snap fastener section provided with the filament guide portions, may be compared with a knot with the plate portion or analogous component itself constituting a part of the knot. As indicated earlier, the filament portion is made to pass or penetrate through the carrier, such as garment without any need for the use of needles. This presents two somewhat contradictory requirements in that on the one hand the filament portion should be as flexible as possible in order to permit the formation of the loops and changes of directions, whereas on the other hand, such flexibility makes it difficult if not impossible for the filament portion to penetrate the carrier web, especially if the carrier web is for instance in form of a textile material which is heavy or of dense weave. To avoid this difficulty it is advantageous if the second section is of greater thickness than the first and third sections, and if furthermore, the tip of the second section is suitably reinforced in a manner still to be discussed. This achieves the desired purposes and further makes it much easier to handle the filament portion during connecting with a carrier web.

It is most advantageous from a viewpoint of economics and of handling if the filament portion is of one piece with the plate portion, button or the like, and it will even be more economical if they are made ofa suitable synthetic plastic material, for instance by injection molding.

The novel features wheich are considered as characteristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Discussing the drawing in detail, firstly the embodiment illustrated in FIGS. 1 4, it will be seen that the securing element here is identified in toto with reference numeral 10 and composed of a filament portion 11 and a plate portion 12. In this embodiment the portions 11 and 12 are of one piece, being made from synthetic plastic material, for instance by injection molding. A material suitable for this purpose is polyamide, although other materials of a synthetic plastic nature can alsobe used and will be readily known to those skilled in the art.

Actually, the element 10 if made by injection molding, will not have at that time its final form. Instead, subsequent to the molding process, the section of the filament portion 11 intermediate the plate portion 12 and the tip will be engaged and subjected to a stretching action to approximately three times (this is of course only by way of example) its original length as molded, with a corresponding reduction in its cross section. This results in an orientation of the molecules of the material in longitudinal direction of the filament portion and imparts to the latter the desired substantial strength.

It is essential during such stretching to assure that the portion 13 where the filament portion 11 joins the plate portion 12 will not be stretched and will remain at its initial thickness because this avoids the danger that the filament portion might snap at this point. Furthermore, the section 14 having the tip 15 is not stretched so that it is thick and more rigid than the other sections of of the filament portion whereby penetration through a carrier web is facilitated.

The tip 15 permits ready penetration through a carrier web 16 without having to first make holes in the carrier web or without having to utilize a needle. This is clear from FIG. 8. The tip 15 can be produced in the most simple manner by obliquely cutting the section 114, and in fact it is very advantageous to produce in a single operation two of the plate portions 12 which are connected by a filament portion 11, and to severe the filament portion 11 midway between the plate portions 12 with a diagonal cut, thereby producing on both of the remaining filament portions the desired tip 15. This eliminates not only the need for a separate operation to produce a tip, but also eliminates the possibility of waste of material.

As the drawing shows clearly in FIGS. 1 4, the plate portion 12 is provided with two filament guide portions for the filament sections 17 and 18, which are diagrammatically indicated in FIG. 1, and which are clearly identified in FIG. 3. One of these filament guide portions is in form of an open groove provided on that major surface 19 of the plate portion 12 which in the connected condition faces away from the carrier 16 (see FIG. 3). The plate portion in this embodiment is of circular outline, although it could of course be of other outline, and the groove 20 is a secant to the circumference of the plate portion. Notches 21 are provided in the margin of the plate portion and each communicate with one of the opposite ends of the groove 20. A pair of passages 22, located in this embodiment at opposite sides of the groove 20, constitute the other filament guide portion and extend through the plate portion 12 from the major surface 19 towards the other majorsurface thereof. The passages 22 are spaced from one another by a distance-corresponding to the diameter of the groove 20 which in turn is approximately equal to the diameter of the section of the filament portion which is to be received in this groove; the latter extends in the illustrated embodiment normal to an imaginary line connecting the two passages 22.

FIG. 3 and the connecting step illustrated in FIG. 9 indicates that the filament portion 11 is to be passed sequentially through the passages 22 forming a loop. To connect the securing element to a carrier web and for instance to a button, the tip 15 is first pushed from the reverse side 23 of the carrier web 16 to the front side 24 thereof, and it is then passed through an eye of a button 25 or through thread holes of such a button, or of course through other suitable connecting portions of another closure member in lieu of a button. Subsequently, the filament portion is passed in reverse direction from the side 24 to the side 23 of the carrier web 16. The filament portion 11 is connected with the plate portion 12 at a marginal location which is remote from the location where the filament guide portions are provided and on reaching the side 23 the filament is first passed through one of the passages 22 and then, forming a loop 26 between the passages 22, is passed back in opposite direction through the other passage 22. Now pull is exerted on the loop 26 until the button 25 contacts the side 24 and plate portion 12 contacts the side 23 of the carrier web 16.

Now, the step illustrated in FIG. 10 is carried out in that the tip 15 of the filament portion 11 is passed through the loop 26 after first bending the filament portion around from the concealed side to the exposed major surface 19 of the plate portion 12. Pull on the free end of the filament portion 11 will now result in entry of the section 14 into the groove 20, with the loop 26 being drawn onto the section 14. Where the filament portion 11 is reversed from the concealed side to the major surface 19, it will enter into one of the notches 21 at the end of the groove 20. Any excess length of the section 14 is cut off where it extends out of the groove 20.

When the connecting operation is completed, the securing element and the button will be connected with the carrier web in the manner illustrated in FIG. 3 and the plate portion with exposed sections of the filament portion will have the appearance illustrated in FIG. 4. Clearly, a section 18 of the filament portion 11 is passed through the passages 22 and straddles the section 17 which is closer to the tip 15 than the section 18. The portion 28 is at the concealed side of the plate portion 12 (see FIG. 3) and is located in one of the notches 21. These rather sharp reversals of direction of the filament portion reduce the tensile force which can be exerted on the filament portion in a sense tending to withdraw it from the groove 20. It ismoreover, highly important that a point ofcrossing or intersection occurs between the sections 17 and 18, where the section 17 straddles and presses against the section 18. Thus, the greater the tensile force exerted upon the button 25, the more firmly the section 18 (the loop) will press against the section 17 and the more firmly the latter will be retained between the section 18 on the one hand and the plate portion 12 on the other hand.

It is illustrated in FIG. 1 that the transverse spacing between the passages 22 corresponds closely to the width of the groove 20 which in turn is so dimensioned as to just accept the associated section of the filament portion. The thin wall portions 29 remaining between the groove 20 and the respective passages 22 become deformed by the pull exerted by the loop 18, and the portion 26 is drawn inwardly towards the bottom of the groove 20 so that even the section 18 becomes lodged completely or nearly completely inwardly of the general plane of the surface 19, and does not project beyond this plane or at least not to any undesirable extent. It is emphasized that this has not been illustrated in FIG. 3, simply because it was thought desirable to show the location of the various sections with reference to one another more clearly which necessitated an avoidance of illustration of this feature. Incidentally it should be pointed out that ifa cross groove is provided in the surface 19, connecting the passages 22 with one another, this desirable recessing of all filament portions in the surface 19 can be further enhanced and facilitated.

In the embodiment of FIG. only the exposed surface l9 of a plate portion 12' is illustrated. The other components of this embodiment correspond to those of the embodiment in FIGS. 1 4, and insofar as illustrated and designated with a reference numeral, are identified with the same reference numeral as in FIGS. 1 4, with the addition ofa prime symbol. The embodiment of FIG. 5 differs from that of FIGS. 1 4 in that the groove 20' is obtained not by forming it in the surface l9' but instead by providing the surface 19' with two pairs of transversely spaced projections 30,30 which are located at opposite marginal portions of the plate portion 12. Only one passage 22' is provided which cooperates in lieu of the other passage 22 in FIGS. 1 4 with a notch or kerf3l provided in the margin of the plate portion 12 and into which the filament portion can of course be still more readily inserted than through a passage 22 or 22.

In the embodiment of FIG. 6, I have illustrated that the plate portion itself can be configurated as a button 25. Here, the filament portion 32 is formed directly on the button 25 on that side thereof which in use will face the carrier web. On the exposed side the button is provided for decorative purposes with a raised rim 33 or the like. Bores or passages 34 are provided in the central region of the button 25 and correspond in their function to the bores or passages 22 in the embodiment of FIGS. 1 4. The exposed side of the button is further provided with an approximately diametrally extending groove 35 which extends normal to an imaginary line connecting the bores 34 and corresponds to the bores 20 of FIGS. 1 4. The embodiment of FIG. 6 is used in precisely the same manner as the embodiment of FIGS. 1 4, except that of course a button is not connected with it because the portion 25 is itself the button. At the reverse side of the carrier with which it is 8 to be connected, the filament portion 32 of the embodiment of FIG. 6 may cooperate with a plate-shaped counter element formed with suitable apertures through which the filament portion can be looped; it is, however, also possible simply to pass the filament portion 32 from the front side to the reverse side of the carrier web and then back to the front side to connect it with the filament guide portion in the manner discussed earlier.

FIG. 7 illustrates that the button 25' of FIG. 6 can also be replaced with a section of snap fastener, here the female or matrix section 35 thereof. The configuration of such snap fastener section is known per se, and it is pointed out that the section 36 is in form of a plate 37 provided with the portions 38 which are to cooperate in snap-coupling manner with the diagrammatically illustrated male or matrix section 37a of the snap fastener. At that side of the plate 37 which in use will face the carrier a filament portion 39 is provided and at the other side the filament guide portions 34 and 35 are provided. The center of the portions 38, the location where the filament portion 39 is connected with plate 37, and the two bores 35' are located on a common line which constitutes a diametric line to the preferable circular plate 37. Thus, the section 36 can be readily and reliably connected to a carrier without any need for sewing. Of course, a similar connection can be established for the matrix which is shown in FIG. 7 in phantom lines, but a detailed illustration or discussion is not believed to be necessary because how this can be done will be self-evident.

It is hardly necessary to point out that other possibilities for modifications and further embodiments will offer themselves readily to those skilled in the art and are to be considered encompassed within the intent and concept of the present invention. Evidently, the plate portion 12 or any analogous portion need not be circular, but can also be annular, rectangular, quadratic, generally polygonal or otherwise configurated. Moreover, a single plate portion 12 can be provided with several filament portions and associated filament guide portions in order to permit a multiple connection with carrier webs.

It will also be appreciated that the section 14 of the filament portion 11 could be made stiffer and more rigid in ways other than by giving it an increased crosssection. For instance, the material of the filament portion 11 in the region of the tip could be chemically treated in order to further harden the synthetic plastic material thereof in the region of the tip with respect to the remainder of the filament portion 11 which must remain flexible. Also, instead of such chemical treatment, it would for instance be possible to cover the tip with a metallic coating, for instance by galvanic means, in which case only a layer of some thousands of a millimeter need be applied in order to obtain a substantial stiffening of the original flexible synthetic plastic and the hardening of the surface thereof in the region of tip 15, which is sufficient to permit penetration as required.

It is of course also possible to make the tip and the portion carrying it of a material different from that of the remainder of the filament portion, for instance of a metallic material, which could be in form of a sleeve into which the filament portion 11 is removably inserted. In such a manner any carrier web at all to which closure members are conventionally connected, for instance leather, synthetic plastic or rubber could be penetrated. Naturally it should not be excluded that a tip might not be formed on the filament portion but that instead the filament portion might be threaded through a conventional needle which is then used to penetrate the web. Also, it is possible to utilize a suitable tool in order to provide the necessary aperture or apertures in the carrier web through which the carrier portion can be pushed, in which case the tip is clearly not required on the filament portion itself.

It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of constructions differing from the types described above.

While the invention has been illustrated and described as embodied in the attaching of buttons or the like without sewing, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention.

Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention and, therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalence of the following claims.
