Description

The invention relates to a push button connection of the type specified in the preamble of claim 1. Metallic push buttons have proven themselves, but they are visually disturbing. There is also an allergy to nickel in some people, which limits the use of these snaps.

There are also push-button parts made of plastic, where on a flange resting on the carrier web there is a one-piece male or female shape _. Dome surfaces are molded. The associated fastening part, for example a toothed ring provided with bendable prongs, is pushed from the back of the carrier through the carrier web, comes out through openings in the flange, so that the bendable prongs come to lie on the front of the flange and cover it. As a result, the attached push button part appears as a disturbing object on the carrier web. The ends of the holding elements fixed in the flange of the push button part form disturbing elevations.

The invention has for its object to develop a push button connection of the type mentioned in the generic term, the easy and convenient of each used Carrier web is customizable. This is achieved by the measures listed in the characterizing part of claim 1.

Due to the special assembly according to the invention consisting of the push-button and fastening part, the face of the flange of the push-button part is largely free, so that the plastic of the push-button part appears in the predominant surface area. If the push button part is made of transparent plastic, the carrier web shines through it after it has been attached, which is why there is an optical adjustment of its own and the push button part is no longer noticeable as a foreign body. Alternatively, the push-button part could also be formed from plastic that can be colored, so that its coloring can be adapted in accordance with the carrier web used in each case.

The holding elements of the attachment member to appear in the novel assembly on the flange _- back of the snap fastener part. They can be attached there in various ways, for example by letting in, in particular spraying, by gluing, riveting or by flanging fastening at the edge. It has proven to be useful to use a prong ring as a fastening part, the ring body of which surrounds the peripheral edge of the flange, so that only a narrow frame-like border appears on the flange of the push-button part on the viewing side. As a result, the rigidity and strength of the push button part is significantly increased without the plastic character of the finished push button connection being significantly impaired in the structural unit according to the invention.

The ends of the holding elements in the assembly according to the invention act on the opposite side of the Carrier web together with a counter-member, which in the case of the preferred toothed ring has an annular chamber which serves to receive and to bend the tine ends. This annular chamber can fundamentally form an annular body, but it is sometimes desirable on the view side to imitate a button character, which is why either the annular body is then closed by a plate formed from the metallic material itself or is covered on the view side by a cap, which in turn consists of a dyeable plastic can exist.

• Fig. 11, partially in radial section, one of Fig. 7 corresponding, but designed as a male part of the push button before it is combined into a structural unit.

In the figures, the push-button connection for male and female molds of two different embodiments is shown in a not yet fully assembled state. In the case of FIGS. 1 to 3, a push-button part 11 designed as a die and a fastening part 12 are combined to form a structural unit lo.

In the present case, the push-button part 11 is formed from transparent plastic 13 and comprises a flange 14, in the center of which an opening 16 having the matrix-shaped coupling surfaces 15 is arranged. The dome surfaces 15 are located on a collar 17 projecting slightly above the upper level of the flange 14 and have radial slots 18 extending from the opening 16 to increase the spring elasticity. Equipped to increase the elasticity and at the same time as the material saving of the flange-t4 is provided with concentrically arranged grooves 19 and on one flange side with concentric grooves 2 _0, 21, leaving the resilient in the coupling surfaces 15 webs 22nd

In the present case, the fastening part consists of a metallic serrated ring 12, which has an array of tines 24 on an annular body 23, the tine ends 25 of which are sharpened. The ring body 23 establishes the connection of the prong ring 12 to the push-button part 11 by a flange 26. The annular body 23 thereby receives a C-shaped profile and engages in the structural unit lo the peripheral edge 27 of the flange 14 with a narrow C-leg 28, which is exaggerated in Figs. 1 and 2. It follows from this that towards the front side 29 of the unit lo the far largest surface area 30 of the unit lo is determined by the transparent plastic 13 of the push-button part 11. The tines 24 are located on the rear of the flange 31 and are no longer visible in the region of the push button part 11 after the assembly of the structural unit 10.

This assembly lo is assembled simply by passing the assembly lo with the prongs 24 through the carrier 32 indicated in FIG. 2. The sharpened tine ends 25 clear their way in the fabric web itself. The entire structural unit lo is therefore on the front side 33 of the carrier web. The tine ends 25 which protrude on the back of the web 34 after passing through interact with a counter-holding member 35, which in the present case consists of a metallic flange ring 35. The flanged ring 35 has, due to the profile of the sheet metal body shown in FIG. 3, an annular chamber 36 which has an annular gap 38 on a central inner flange 37, the annular diameter of which is adapted to the ring arrangement of the tines 24 on the annular body 23 of the serrated ring 12. In the case of assembly consequently, the tine ends 25 guided through the carrier web 32 pass through the annular gap 38 against the inclined inner wall 39 of the annular chamber 36, where they are rolled up and thereby establish a firm connection with the flanging ring 35. This completes the push button connection.

In the completely assembled structural unit lo, the carrier web 32 with its colored pattern of the front side 33 shines through the surface area 3o Plastic 13 through. Only the narrow frame 28 can be seen towards the front side 29 of the structural unit, but this no longer disturbs the good appearance. Due to this frame-shaped enclosure, the flange 14 of the push button part 11 is stiffened in the structural unit lo. The push-button part 11 is connected to the carrier web 32 in an extremely stable manner.

4 and 6, the associated matrix-shaped component of the push-button connection according to the invention is shown. Therefore, the measures described so far largely apply, which is why it is sufficient if only the deviations are described below. In this unit lo ', the push-button part 11' is a push-button male 11 'which is also formed from a one-piece transparent plastic 13' in the present case. The male part 11 'comprises a flange 14', which has an edge-side shoulder 4o on the face side compared to a stronger central plate part 41. Here too recesses 19 'and a groove 2o' are provided on the flange rear side 31 'to save material. The male-shaped dome surfaces 15 'are formed by a central mushroom-shaped attachment 4.2. To increase the elasticity and to save material, the neck 42 is also equipped with a central bore 43.

A fastening part belongs to the structural unit lo ', for which the toothed ring 12 already described in connection with FIGS. 1 to 3 is used, which is why its formation and combination with the flange 14' need not be described again. For the production of the push-button connection, the tines 24 interact in the manner already described with the fabric web 32 also indicated in FIG. 5, while the tine ends 25 emerging on the back of the carrier web 34 cooperate with one cooperate differently with respect to FIG. 3 designed retaining ring 35 '. This initially consists of the previously described flanging ring 35, the annular chamber 36 of which receives and rolls up the tine ends 25 in the manner described above. The outward-facing surface of the flanging ring 35 is additionally covered with a cap 44 made of plastic in this counter-holding member 35 ', so that this counter-holding member 35 acts like a button to the outside. There appears an outwardly closed surface 45 on the counter-holding member 35 ', which can first achieve an appearance adapted to the carrier web 32 by coloring, but then ensures good application of force especially for coupling the two complementary push-button parts in the structural units lo, lo'.

After completion of this connection, essentially only the plastic 13 'of the male-shaped push button part 11' appears on the front side 33 of the carrier web 32, which is why the color appearance of the carrier web side 33 can shine through. Here too, the frame-shaped, exaggerated border 28 of the structural unit 10 'does not disturb this automatic adaptation of the structural unit to the carrier web 32. This border 28 comprises only a very narrow zone on the peripheral edge 27 'of the flange 14'.

As has already been explained, the invention is not restricted to the exemplary embodiments shown; First of all, the push-button parts 11, 11 'can be made of another one-piece plastic, which can consist of a plastic that can be colored instead of transparency. The coloring takes place in adaptation to the respective face 33 of the carrier web 32.

The structural unit lo, lo 'could have other fastening parts instead of the toothed ring 12 shown, e.g. Rivets or pins. These could be glued, welded or injected into the plastic 13, 13 'on the back 31, 31' of the flange 13, 13 '. A ring body is not required in the latter cases, because the holding elements could be embedded directly in the flange. It goes without saying that, depending on the type of holding elements of the respective fastening part used in the structural unit lo, lo ', the associated counter-holder 35, 35' must be adapted.

As a further variant, the annular chamber 36 of the flanged ring 35 in FIG. 3 could be closed at the point where the inner ring opening 46 is provided, so that a continuous plate is formed which is already without an additional cap 44, as in the case of FIG. 6, how a closed ring body acts. This plate closing the ring opening could have profiles and patterns, as is desired with a button.

7 to 11 show two further exemplary embodiments for forming a structural unit 10 ", which are formed in a manner contrary to the previous exemplary embodiments from a push-button part 11" or 11 "" and a toothed ring 12 "" ^q embodiment of Fi. 7 to lo is the knocking body 11 '' ausaebildet as a template, based on which the particular construction can be seen.

7, the push button part 11 "consists of a plastic plate 46 of predetermined plate thickness 47, which is cut out of a plastic sheet and shaped into a cup 50 with a U-shaped profile in a radial section becomes. The cup base 51 contains the matrix-shaped dome surfaces 15 ", which are similar to those of the first exemplary embodiment from FIGS. 1 and 2 and have an opening 16". Because of its shape from the web, the plate thickness 47 is essentially the same everywhere, which is why there are no significant thickenings in the area of the dome surfaces 15 ″ and profile bends 52 are provided instead.

The serrated ring 12 ″, apart from the smaller number of tines 24 ″, namely five, has a different design of the ring body interacting with the push-button part 11 ″, which is designed here as a flat ring 48, on the inner edge of which the bendable tines 24 '' are arranged. This ring 48 has an outer circumference which fits into the width 53 of the cup 5o from the push-button part 11 ″, which is used in the construction of the structural unit 10 ″ according to FIG. 9. After the toothed ring 12 ″ with its flat ring 48 into the Inserted inside the cup _55 and reached the inner surface of the cup base 51, the side walls 54 of the cup are flanged so that they encompass the outer peripheral edge 57 of the flange-like ring 48. This completes the structural unit 10 ", which is in section from FIGS is shown in the bottom view in Fig. lo. The assembly of the push-button connection takes place in a manner already described in the previous exemplary embodiments by means of a counter-element arranged on the back of the carrier web to be equipped therewith, which is expediently designed according to FIG is formed from a plastic plate. Appropriately, for this plastic cap 44, the same material is used in the same color as when the plastic plate 46 forming the cup 50 is formed Snap part 11 '' used. As a result, the face of the counter-member 35 'and the assembly 10 "have the same shape; one only sees the uniform plastic. In the assembly 10", the toothed ring 12 "is made invisible.

In a manner corresponding to FIGS. 7 to 10, a push-button part 11 '' 'having male-shaped dome surfaces 15' '' is formed, which is why the previous description with the same reference numerals as in the previous exemplary embodiment is used in this respect. It is sufficient to describe the deviations. In the cup base 51, the material of the plastic plate 46 is shaped like a mushroom in the central area, so that there is a cavity 56 pointing into the cup interior 55 at the dome surfaces 15 '' '. In some applications, this cavity 56 is provided with a filling compound which gives the coupling surfaces 15 '' 'greater rigidity. The procedure for creating the corresponding structural unit is the same as that described in connection with the matrix-shaped push-button part 11 ″ in FIGS. 7 to 10. The side wall 54 of the cup 5o serves for the flanging around a flange-like ring 48 of a fastening part 12 ″ provided with teeth 24 ″, as shown in FIG. 8.

In some applications it is advisable to form the plastic plates 46 described for the push-button parts 11 ", 11" '' and for the plastic caps 44 on the counter-holding member 35 'from a transparent film web, which consists, for example, of polycarbonate.

This transparent film is printed on the back and is then used to cut and shape the above-mentioned push button parts or plastic caps. The pressure is then on the inside indicated in FIGS. 7 and 11 Surface 49 of the cup 5o shown in FIGS. 7 and 11, but also the cap 44, where the colored print shines through the film material to the face of the object. The print is shielded against scratches, but still appears as brilliant as if it were provided on the surface.

The plastic plates 46 for the push button parts 11 ″, 11 ″ ″ and counter-holding members 35 ′ could of course also be formed in the required hollow shape instead of flat foils or webs, e.g. by an injection molding process.
