Button, especially upholstered button

The invention relates to a button, in particular an upholstered button, with an outer cover.

A well-known, commercially available upholstered button has an outer shell with conically bevelled side walls, which encloses a button insert and for fastening both this button insert and a button cover serves. The well-known button insert has smooth Side walls, and the holding forces or the resistance to inadvertent separation of the button insert the outer shell depends only on the surface friction on the surface between the button cover material and the button insert. It therefore happens again and again that well-known upholstery buttons dissolve into their individual components, although excellent hemming or flanging tools are used during assembly used.

That is why people have given a lot of thought to how to prevent the buttons from being separated can. In the case of a known button, the button insert made of sheet metal has a radial one Flange or a lip provided at the upper end of its lateral boundary, so that the button insert better is held in place by the inwardly curled sidewall of the outer shell of the button. In principle it represents the arrangement of this flange or this lip is essentially only an attempt, the overlap to enlarge the side wall of the outer shell compared to the boundary of the button insert.

A well-known upholstery button has an eye or a hook for attachment to its button insert an upholstery loop on the button. If you use a closed eye, the cushion sling is reliable secured against unhooking, but during assembly there is a need to pull the thread through pulling the eye and then tying it into a loop. If you use a hook, you can use a prefabricated loop or cushion loop. However, such hooks have the disadvantage that the upholstery loops can be easily unbuttoned if someone treats the button improperly or with it plays. Also known ones equipped with a multiple hook Upholstered buttons are not sufficiently "fumble-proof". For example, with a well-known The upholstered button of the hook has the shape of a double U with two hook sections on opposite sides of a common shaft. Apart from other disadvantages of this known button insert found that the cushion loop is very easy to remove from both hooks.

The invention is based on the object of creating a button, in particular an upholstered button, which is simple hang in a prefabricated upholstery sling, but not inadvertently detach it, and its Button use is so improved that with pronounced Interfering with the button cover of the outer shell is dangerous unintentional separation of the buttons is excluded.

According to the invention this object is achieved in that a core which can be inserted into the outer cover and has a core set up to accommodate a cushion sling or the like Hook approach is present.

Preferably, the approach is provided with a recess for receiving the Polsterschlinqe, the two snap locks are assigned in such a way that the cushion loop when inserted into the recess one after the other must be snapped past both snap locks.

In this way it is achieved that a prefabricated cushion sling is easily hooked into the approach, however cannot be accidentally removed from it.

One of the snap locks can consist of a shaft and a hook portion of the attachment, and the other Schnappverrxeqelung consist of a projection of the core and part of the hook portion. It is located An additional recess is preferably located between the two snap locks.

Preferably, the core has a number of shoulders on its periphery with intervening outer shoulders.

surfaces, which the circumference of the core in step sections divided, the distance of which increases progressively from the center of the nucleus. There they go Shoulders preferably each have an edge which is designed to engage in a covering material of the button is, into the .adjacent outer surface. In this way it is achieved that several Be able to dig edges deeply and safely into the covering material. Unintentional opening or a shift of the core relative to the outer cover with button cover is reliably prevented.

A particular advantage of a button or upholstery button designed according to the invention is that that it can be quickly removed even by inexperienced workers and can be easily connected with an upholstery loop. Later unintentional loosening is impossible, because the upholstery loop is only forced in the opposite direction through the barb-like snap locks would have to be brought through, which is very difficult. Even after overcoming the first Snap lock still prevents the second snap lock, which is just as difficult to overcome is a loose.

A preferred embodiment of the invention is described below with reference to a drawing explained in more detail. Show it:

The upholstered button shown in the drawing and composed of several parts has a core 1 in Form of a plastic element made in one piece from nylon or other suitable material Externally, this plastic element 3 can be in a Base 5, an upper part 9 and a peripheral surface 9 connecting the base to the upper part are divided, and its central axis coincides with a perpendicular to the base 5 surface 11 together. In the present embodiment, according to the usual configuration of upholstery buttons, Base 5 and upper part 7 are circular in plan view.

The circumferential surface 9 is subdivided in steps by annular circumferential shoulders 13, 15 and 17 in such a way that that the outer diameter of the plastic element 3 progressively towards the upper part 7

309834/0348

increases «The shoulders preferably run 13, and 17 parallel to the base 5 and to the top of the upper part 7. In this way is the peripheral surface 9, seen from the base 5, divided into individual lateral surfaces 23, 19, 20 and 21, of which the lateral surfaces 23, 19 and 20 are essentially cylindrical run, while the uppermost individual lateral surface 21 preferably at an angle of approximately 12 ° is inclined conically outwards. As an alternative to the graphic representation in Figures 1 to 3, all of the lateral surfaces 19, 20, 21 and 23 can be either cylindrical or slightly conical be. It essentially depends on each at the transition of each shoulder 13, 15 and 17 to the jacket surface 19, 20, 21 lying above it, a circular edge 25, or. 27 or 29 with progressively increased diameter Of course, the number of shoulders and lateral surfaces can also vary from the illustration differ in the drawing if desired.

According to FIGS. 1 and 2, the finished upholstery button includes a metallic enveloping body 31 with an essentially circular upper bulge 33 and a conical wall section 3 5, which at a distance the circumferential surface 9 of the core 1 encloses. The metallic enveloping body 31 is finally with a coating 37 coated from textile fabric, plastic or the like, which the curvature 33 and the conical Wall section 35 of the enveloping body 31 encloses and around a lower edge 41 of the enveloping body inwardly in is pulled around in such a way that a turn-up portion 39 is formed which defines the space between the circumferential surface 9 of the core 1 and the conical

309834 / 03A8

Wall section 35 of the enveloping body 31 fills. During manufacture, this state is established in that the initially cylindrical wall section of the enveloping body 31 by a suitable squeezing tool is pressed into its graphically shown conical configuration. This is where the envelope section 39 of the coating 37 is pressed against the edges 25, 27, and 29 of the core 1 and flows (see Fig. 2) into the relaxation rooms formed below the shoulders 13, 15 and 17. The flow of the coating material into these relaxation spaces creates a extremely resistant, form-fitting connection between core 1 and enveloping body 31 with coating 37. Inadvertent detachment of the core from the upholstery button is largely excluded.

According to FIGS. 4 and 5, a projection 45 extends from the base 5 of the core 1 with an essentially axially extending one Well section 47, which runs back down in an arc in the direction of the base area 5 and there forms a hook portion 49 which has an inwardly angled upper curvature 51 ends. The end of the bulge 51 is formed by an end section 53 parallel to the surface 11. The shaft section 47 is externally connected to the hook portion 49 by a lower arched rib 55. According to FIG. 4, the runs The axis of symmetry of the core 1 through the surface 11. A gap 57 is formed between the surface 11 and the end section 53, through which the upholstery loop 59 can be buttoned in order to finally receive it in a recess 61 to find.

In addition, protrudes from the base 5 (which can be a part of the extension 45) through a lower end.

• Area 65 limited elastic nose 63 out. Between this end face 65 and the upper bulge 51 of the Shaft section 47 forms a gap 67 which forms the gate to a further recess 69. The gaps 57 and 67 are narrower than the diameter of the thread of the cushion loop 59.

The elastic nose 63 and the upper arch 51 of the hook portion 49 form a snap lock, which the cushion loop 59 must pass when hanging in the core 1. Another elastic snap lock is formed between the hook portion 49 and the shaft portion 47, which is the cushion loop 59 must happen when it is hooked into the recess 61. The prefabricated upholstery sling is therefore forced through two snap locks before it enters the recess 61. This The process can easily be carried out with any suitable mounting device 77 (see FIG. 7). In Fig. 8 a section from a finished cushion element 73 is shown, which is supported by a cushion loop 59 is braced with an upholstery button 71 or 71 'at each end.

The cushion loop 59 is pushed through the cushion element by means of a conventional needle (not shown) 73 passed through so that the upholstery button 71 rests against a lower surface 75 of the upholstery element 72. Then the upper end of the cushion loop 59 is grasped by the mounting device 77 and buttoned of the upper upholstery button 71 · raised. After pulling out the assembly device 77 take the two Upholstery buttons 71 and 71 »theirs shown in FIG

Location a. Since the upholstery loop engages each upholstery button close to its axis of symmetry the buttons are also loaded axially and lie flat against the outer surface of the upholstery element.

By lateral pressure on the cushion element 73 (for example by a person sitting down) it can happen that the approach 45 of the upholstery button is exposed and gives cause to play with it. It has been found that it is extremely difficult to get the cushion loop 59 backwards through the gap 57} should this case nevertheless occur, so the cushion loop 59 would now be in the other recess 69, which through the from the elastic nose 63 and the upper bulge 51 formed snap device is secured. To the To bring upholstery loop through this second snap device, one would first have to insert it Pull out another piece of the cushion sling and try to pull it through the gap in the opposite direction 67 to urge. The inadvertent overcoming of both snap locks is extremely difficult, so that an unintentional loosening of the upholstery buttons according to the invention is effectively prevented.

In summary, the invention relates to an upholstered button with an integrally molded core, the Circumferential surface is stepped off. Becomes an enveloping body squeezed onto the core with the coating material drawn over it, so those of the separated ones are stamped Steps formed circumferential edges of the core into the inwardly folded coating material and prevent effective an unintentional loosening of the core »There is a hook on the underside of the core
