Definitions

  • the invention is directed to a snap fastener of the type specified in the preamble of claim 1.
  • the mutually complementary coupling surfaces of the male part engage in the female part and thus ensure a connection between the two carriers, to which these parts are each attached.
  • the male part has, due to its function, a thickened head on its dome surface, which sits on a neck that is slimmer in comparison.
  • the neck merges into a plate that sits on the top of the carrier and is fastened there by fasteners.
  • the known die parts have a similarly large overall height above their support, because they are seated on a plate seated on the associated support with a recess adapted to the aforementioned shape of the male-shaped coupling surfaces.
  • the invention has for its object to develop a snap fastener, the die part is designed to be easier through a easier assembly and, above all, a low overall height. This is achieved according to the invention by the measures specified in the characterizing part of claim 1, which have the following special meaning:
  • Eyelet rings are known per se as donrdashery items. They are usually used for carrying cords, hooks, loops or the like when they are attached to a carrier in the region of a hole cutout which they surround in a frame-like manner.
  • the invention has recognized that it is sufficient during the coupling process to use the male-shaped dome surfaces as elastic elements and an eyelet ring known per se to assume the new function of a "female part" because its eyelet opening can be used as a male-shaped dome surface.
  • the eyelet ring has a minimal overall height and does not require any special fastening elements, because it is generally constructed from two annular halves, which overlap the front side and the rear side on the one hand and are connected to one another by connecting elements, according to claim 3, that are passed through the hole cutout. 5 is sufficient if one starts from metallic eyelet halves according to claim 4. All of this results in a low height of the die part according to the invention, which is only slightly thicker than the thickness of the carrier.
  • the flange of the upper half is on one side of the support and the washer of the lower half is on the opposite side.
  • the two halves are connected to each other by crimping, so they provide the connecting elements themselves.
  • the neck protrudes through the eyelet opening and essential parts of the dome surface come to lie on the face of the two interconnected beams in the eyelet opening and develop interesting decorative functions there. This is especially true if there are colored or patterned male domes or eyelets.
  • the male dome surfaces are enclosed by the eye ring coupled with it like a picture frame.
  • the snap fastener serves to connect two carriers 10, 20 to one another via push button parts 11, 21 that are complementary to one another.
  • These push-button parts 11, 21 have special matrix-shaped coupling surfaces 12 on the one hand and male-shaped coupling surfaces 22, 23 on the other hand, which is why they will be referred to in the following as “matrix part 11" and "male part 21".
  • the male part 21 consists of the actual functional part which, after assembly, comes to rest on the visible side 28 of the carrier 20 shown in FIG. 3.
  • a flange 24, which is supported on the face 28, is used for this purpose.
  • the flange 24 is provided in one piece with a narrowed neck 23 and a thickened head 22, which form the actual dome surfaces.
  • the entire male part 21 is made in one piece from plastic. This can also be colored and / or patterned on the top of its head 22.
  • This functional part 21 also includes a fastening part 25, which can be designed in a manner known per se, in the present case it is a fastening pin.
  • a fastening part 25 generally consists of a plate 26, which comes into contact with the mounting on the back 29 of the support, and one or more holding elements 27, namely, in the present case, a central pin. In the case of assembly, this pin makes its way through the carrier web 20 itself and interacts with the functional part 21 on the opposite side. During assembly, the pin 27 penetrates into the plastic material of the functional part 21 on the carrier face side 28 and settles there. A so-called bicorn or a serrated ring could also be used as holding elements 27.
  • the die part 11 is designed here in a special way, namely as a so-called "ring eyelet”.
  • This consists of two annular halves 13, 16 which are profiled from sheet metal and which have the special appearance shown in FIG. 2.
  • the upper half 13 of this eyelet 11, which comes to lie on the carrier face side 18, comprises a flange 14 with a tube 15 connected in one piece to it.
  • a profiled annular disc 16 comes to rest as the lower half 16.
  • the washer 16 may be formed as a finished decorative ring.
  • connection of the two ring eyelet halves 13, 16 to the carrier 10 is achieved by riveting tools or the like, a hole cutout 30 being formed at the desired location either during riveting or beforehand, which approximately corresponds to the diameter of the upper half tube 15 corresponds to.
  • these two parts are pressed against one another in the case of assembly in the direction of the arrows 32 shown, the tube 15 being guided through the hole cutout 30 until the flange 14 is supported on the face side 18 of the support.
  • the free pipe end 31 then protrudes on the back of the carrier 19 and can cooperate with the washer 16 located there, which has meanwhile also come to rest on the back of the carrier 19.
  • the riveting tools or the like now lead to a flanging of the pipe end 31 into the rolled-up position 31 'shown in FIG. 4, with which a firm cohesion between the two ring eyelet halves 13, 16 has been achieved.
  • the tube 15 passes through the hole cutout 30 and reinforces the edge of the hole with washer 16 and flange 14. This results in the structure shown in FIG. 4, the eyelet opening 12 forming the actual matrix-shaped coupling surfaces of this matrix part 11.
  • the die part 12 has a relatively small overall height 33, which is also exaggerated there to demonstrate the structure. Apart from the two cooperating eyelet halves 13, 16, no further fastening parts or holding elements are required.
  • the thickness 34 of the carrier 10 is subtractively included in the overall height 33 of the die part 11, which is why it only insignificantly projects beyond the carrier on both sides.
  • the ring eyelet 11 composed of metallic halves is relatively dimensionally stable, but this can be compensated for by an appropriate selection of the plastic material for the male part 21.
  • the deformation required during the coupling process takes place itself in the area of the male head 22.
  • the male head 22 with its cap 35 is visible in the eyelet opening 12 of the female part 11 and may protrude somewhat. It therefore develops a decorative function on the carrier face side 18 within the flange 14, which then acts like a frame-shaped border. For this reason, the colored or patterned designs of the male cap 35 or the eyelet 11 already mentioned several times are suitable.
  • the above-described male head 22 In order to enable a particularly smooth engagement, it is advisable to provide the above-described male head 22 with a shape that deviates from the round outline, namely in particular to make it out of round, while the eyelet opening 12 has a circular shape.
  • 5 shows an alternative male part 21 'in plan view.
  • the male head 22 ′ there has different peripheral regions 36, 37.
  • Radially projecting regions 36 are provided there, which project approximately as far as the male part 21 shown in the previous exemplary embodiment of FIG. 4 does.
  • the male part 21 'of FIG. 5 also has radially recessed zones 37, which have come about here by making the male head 22' slimmer on its original circular outline by secant cuts.
  • the projecting areas 36 experience a lighter deformation, which is why the coupling of this male part 21 'into the eyelet 11 described above is easier than in the case of the male part 21 shown in FIG. 3. This can be done by a corresponding steep transition between male head 22' and the corresponding male neck However, make decoupling more difficult if one is keen to hold the snap fastener 11, 21 'more securely in engagement with one another.
  • the male part 21 ′′ there consists of a cylinder 40, the latter later a cylinder end 41 associated with a carrier 38 is provided with a flange 42, while its opposite cylinder end 43 functions as a closing head in that radial cams 44 project there in a uniform arrangement.
  • This male part 21 ′′ has a hat shape and at its hat opening defined by the cylinder end 41 there is a receptacle 45 in a longitudinal arrangement, which cooperates with a special holding element 50 for attachment purposes of the male part 21 ′′.
  • a pipe socket 47 is arranged coaxially in the interior of the hat 46.
  • the cylinder 40 and the pipe socket 47 are thus concentric.
  • the pipe socket 47 is integrally formed on the hat bottom 48, the inside of the pipe forming the already mentioned receptacle 45.
  • the radial cams 44 form a rim extending at the cylinder end 43, the cylinder end 43 being flattened such that, after the connection shown in FIG. 10, this closing head is almost flush with the top of the eyelet 11 on the carrier 10 there.
  • the holding element 50 used here consists of a special double pin 50 with two pin ends 51, 52 facing away from each other.
  • Each of these two pin ends has a sawtooth profile 53, 54, which is designed here to be rotationally symmetrical to the pin axis 55.
  • the two sawtooth profiles 53, 54 are mirror images of one another, the steep flanks being directed away from the pin tips 56, 57. This gives the two pin ends 51, 52 a pagoda-like appearance that is opposite to each other.
  • This double pin 50 is first preassembled with a previously described hat-shaped male part 21 ′′ by pressing the one pin end 51 into the receptacle 45 described. This results in a structural unit which can be seen in FIG. 9 and from which one pin end 52 protrudes. In order to determine the penetration depth of the processed pin end 51 in the structural unit 49, it is advisable to provide a collar 58 as a stop between these two pin ends 51, 52, which, as can be seen from FIG. 8, expediently tapers conically towards the free pin end 52.
  • This assembly 49 now forms in connection with the preassembled double pin 50 a fastening part, which in turn is now with a cooperates second male part 21 ′′, which is expediently identical in shape to the above-described first male part belonging to the structural unit 49.
  • the pin end 52 is here also passed through an assigned carrier 38 and reaches the corresponding receptacle 45 of the opposite male part 21 ′′.
  • the two male parts 21 ′′ thus lie on mutually opposite sides 39, 59 of the carrier 38 in a position that is antiparallel to one another, preferably aligned on the same axis. They are ready to interact either selectively or simultaneously with two further die parts 11, 11 ', as is explained in more detail in FIG. 10.
  • each of the two combined male parts 21 ′′ is assigned a female part 11, 11 ′ in the form of the ring eyelet already described, which are each mounted on their own carriers 10, 10 ′.
  • this could also be a common support, where the two die parts 11, 11' are located in different support sections, which in use are on the two opposite sides 39, 59 of the carrier side 38 come to rest.
  • This results in the possibility of engaging a layer of fabric 10, 10 'on both sides with the combined male parts 21' '.
  • upholstery covers for garden furniture in which an inner cushion is provided with a washable cover. The cover fabric can then be pressed onto the combined male parts 21 ′′ from both sides.
  • the eyelet 11 ' is of a modified design because a profiled plastic ring 61 is used instead of the metal lower half 16.
  • This plastic ring 61 has a stepped step 62 in the inside of the ring, on which the previously described flanged pipe end 31 'of the upper half 13 is supported.
  • the plastic ring 61 In its rounded rectangular cross section, the plastic ring 61 has an overall height in which, after coupling, the male part 21 ′′ is concealed; its slightly curved free cylinder end 43 is almost flush with the end face of the plastic ring 61, as can best be seen from the modified embodiment in FIG. 11.
  • FIG. 11 shows an alternative where two male parts 21 ′′, which are again identical to one another, are combined to form a double male 60. This is done by pressing the male parts 21 ′′ against the common double pin 50 without an intermediate covering material and therefore touching their cylinder ends 41 on the foot side.
  • the dome surfaces which again consist of the radial cams 44, are directed away from one another.
  • This double male 60 is now indirectly assigned to the carrier 10 'via the female part 11'. This is done by engaging the ring part 11 'provided on the carrier 10' with the corresponding coupling surfaces at one end of the double patrix 60.
  • the double male 60 is now part of the carrier 10 'and the opposite free male part 21''is now ready to be coupled to the female part 11 of another carrier 10 in the manner already described several times.
  • the difference of this embodiment from that of FIG. 10 is therefore that the double patrix 60 does not have its own carrier.
