"Push button connection for the detachable coupling of an actuating button from an extension of a male part"

III I Im* 'II "', *!!.*. Hi 2695a/99

Description:

The invention relates to a snap fastener connection for the detachable coupling of two fabric parts with a female part on one fabric part and a male part on the other fabric part as well as with a pin-like extension of the male part which is connected to an actuating button.

In a snap fastener connection of this type according to DE 299 01 685 Ul, a cross-slotted truncated cone is connected to an operating button via a polygonal surface, with a hemisphere adjoining the smaller truncated cone surface. The truncated cone passes through a male upper ring and a female lower ring and is coupled to these two rings via a plug in that when the truncated cone is pressed into a corresponding recess in this plug, the parts of the cross-slotted truncated cone retreat like a leaf spring until the hemispherical parts grip behind an edge of the plug. The operating button, together with the polygonal surface and the truncated cone, is designed as a rotary knob, so that when it is rotated, the two material parts held between the male rings on the one hand and the female rings on the other can be uncoupled from one another.

III II ,''II *·*. *!!.*. Hi 2695a/99

The disadvantage of this push-button connection is that the operating button, including its polygonal surface and truncated cone, can only be removed from the male rings with great difficulty and only by destroying either the hemisphere or the plug. However, such a solution may be necessary if the operating button is damaged or if it is to be replaced with another operating button that is subject to changing tastes over time.

The same applies to a generic push-button connection according to DE 299 07 999 Ul, in which the actuating button is connected via a gear ring on its underside to a pin-like, circular cylindrical extension, to which a detachable clip connection in the form of a small hat cylinder is connected. Both the pin-like extension and the hat cylinder are provided with a cross slot, whereby the slotted parts form leaf springs. As a result, the slotted parts of the hat-like extension can retreat like a leaf spring when penetrating the opening of a plate until the plate rests against the underside of the extension of the rotary knob and its underside is gripped by the clip connection of the hat-like extension.

Even with this push-button connection, the actuating button can be detached from the plate and thus from the male part

III II ,''II'",''.I.'. Hi 2695a/99

can only be replaced using a special tool or by destroying the plate or the clip connection.

Furthermore, in a known push-button connection of this type according to DE-PS 454 523, the male part consists of a pin with a circular cross-section and a free, dome-shaped end as an actuating button, and is provided with a circular groove as a recess below it. The female part accommodates an essentially W-shaped, hexagonally bent spring, the spring ends of which are designed as spring pins and, in the closed position, spring-loadedly engage in the circular groove of the male part. To release this engagement, the actuating button, which is connected in a rotationally fixed manner to a tubular hollow cylinder, must be turned. Rhombus-shaped cuts are provided as recesses in two diametrically opposite sides of the hollow cylinder, through which the two opposing spring pins engage in the circular groove of the male part.

When the rotary knob is turned, the spring pins that initially rest against the recesses of the tubular hollow cylinder are pushed back to its outer peripheral surface, whereby they simultaneously come out of the annular groove of the male part, so that the actuating button can then be pulled upwards with the tubular hollow cylinder of the female part. This push-button connection also has the disadvantage that the circular pin cannot be released from the actuating button and thus cannot be replaced by another, temporally

Page 5 . ."..·'. .".I**' .·*.··*: 17.04.2003

This snap fastener connection also has the disadvantage that, in order to pull out the snap fastener, considerable frictional forces must be overcome, which are caused by the pre-tensioned spring pins rubbing against the wall of the hollow cylinder. When overcoming these frictional forces, the user also exerts pulling and tugging forces on the fabric part held by the die part. This is particularly true if the snap fastener connection is used as a pull button to release the coupling. For this reason, this snap fastener connection is only suitable for very robust items of clothing, for tarpaulins or for the tops of cars. And finally, the relatively large overall height of this snap fastener connection is also a nuisance.

Based on this prior art, the invention is based on the object of creating a push-button connection of the type mentioned at the outset, in which the actuating button can be quickly exchanged for another actuating button of a different shape, made of a different material and with a different appearance without changing or replacing the die parts or the die parts.

This object is achieved in accordance with the invention in connection with the generic term mentioned at the outset in that the extension and the actuating button are designed as separate,

Page 6 II** ... 17.04.2003

III II .* * II "*. ';; , ', Hi 2695a/99

however, parts are designed to be coupled to one another without tools, the extension being provided at its free end with a truncated cone with at least two diametrically opposed locking recesses in its outer surface, into which two spring pins arranged on or in the actuating button engage for coupling, the locking forces of which are greater than the tensile or torsional forces for releasing the male part from the female part for uncoupling the two material parts. This design creates a "snap fastener connection within a snap fastener connection", whereby the actuating button can be quickly released from the pin-like extension of the male part. To do this, simply hold the extension of the male part and turn the actuating button, whereby the spring pins and the actuating button disengage from the locking recesses of the truncated cone on the extension. The actuating button is then released from the pressure connection and can be quickly coupled to another actuating button of the same or different shape, different design or different material by simply pressing onto the truncated cone of the extension of the snap fastener connection.

To uncouple the actuating button from the pin-like extension of the male part in the form of a truncated cone, it is advantageous to first separate the female part from the male part, because then the lower end of the male part is free and can be quickly removed by hand or by means of

Page 7 II .··..". .".I*",","", 17.04.2003

a tool and can be held to release the operating button.

It is advantageous to have six pairs of diametrically opposed

Locking recesses of the same length are arranged, whereby the actuating button only needs to be turned by an angle of 60° to release it from the truncated cone of the pin-like extension of the male part. 10

It is understood that as the number of locking recesses increases, this pivot angle becomes smaller and as the number of locking recesses decreases, it becomes larger.

To prevent the actuating button from accidentally and therefore undesirably coming loose from the truncated cone, the locking recesses in the truncated cone have a semicircular cross-section and are slightly longer in their opening area than their diameter, with the spring pins having a correspondingly large circular cross-section that fills the semicircular area and the opening area. This design, in particular the extension of the opening area, prevents the actuating button from coming loose from the truncated cone by accidentally pulling or tugging on it. It can only be released by turning the actuating button while simultaneously holding the pin-like extension of the male part.

However, it is also possible for the locking recesses to have a rectangular cross-section, which is filled by a spring pin with a correspondingly rectangular cross-section. Even with this form, the decoupling principle of the rotary connection between the rotary knob and the pin-like extension of the male part is retained.

To ensure that the push button connection remains flat, the side of the actuating button facing the extension with the truncated cone is provided with a sleeve-like extension with diametrically opposed recesses in which the spring pins are held running approximately parallel to one another. The word "approximately" is intended to indicate that the spring pins only run parallel to one another in their locked position, but in their released position, as their preload increases, they become convex, bent outwards away from the truncated cone. With such a convex shape, the spring pins no longer run parallel to one another.

To ensure that the snap fastener connection remains flat and can therefore be used on practically all items of clothing, the male part has a flat male upper ring with a circular collar, into which an equally flat male lower ring with a circular projection is positively and/or

can be fitted in a force-locking manner, whereby the male rings clamp the upper material part between their circular ring flanges in the outer peripheral area.

The die part also has a flat die upper ring with a circular collar on its underside and a flat die lower ring with a circular projection on its upper side that can be fitted into the collar of the die upper ring in a form-fitting and/or force-fitting manner, wherein the die rings clamp the underlying material part between their circular ring flanges.

According to a particularly advantageous development of the invention, the part adjoining the truncated cone of the extension is designed as a bolt, the end of which facing the die rings is designed as a second truncated cone with several locking recesses in its outer surface, arranged in pairs and diametrically opposite each other, into which two spring pins arranged at a distance in the die lower ring and held parallel to each other lock. The die part and the male part are thus connected to one another using an identical coupling and release principle as is found in the coupling of the actuating button with the pin-like extension of the male part. This not only simplifies the manufacture of the snap fastener connection, but also its application to textile items of clothing. This is particularly true when the locking recesses are in

II Δ*..". .".&Ggr;* ,","", April 17, 2003

the second truncated cone facing the die part has the same shape and design as that in the first truncated cone and the spring pins are designed accordingly.
5

The second truncated cone is advantageously provided at its end facing away from the die part with a circular collar with a larger diameter than the opening of the male lower ring, but with a smaller diameter than the openings of the die rings. This means that the bolt is held securely between the male rings and the actuating button on the one hand and, after being released from the die part to replace the actuating button, can be quickly grasped at the underside of the male lower ring and held in place to release the actuating button on the other. According to a particularly advantageous development of the invention, this holding is simplified in that a recess such as a Phillips slot or a polygonal blind hole is provided in the second truncated cone facing the female lower ring for the engagement of a tool such as a knife tip, nail file tip or polygonal mandrel to hold the bolt in place when the rotary knob is to be uncoupled. To do this, simply insert the tool into the blind hole, hold the bolt in place and turn the knob in one of the two possible directions to decouple it from the bolt. The new knob is

.' I Δ*..". .". &Ggr;" .··."·: April 17, 2003

then coupled to the bolt by simply pressing it onto the first truncated cone.

In order to prevent the rotary knob from accidentally coming loose from the bolt when the snap fastener connection is released, i.e. when the male part is released from the female part with the respective separate material parts, the locking forces, in particular the pre-tensioning forces of the spring pins holding the rotary knob on the first truncated cone, are greater than the spring pins in the lower ring of the female that engage in the locking recesses of the second truncated cone. This pre-tensioning of the spring pins is advantageously regulated by their spring hardness, their material type, their tempering and their geometric dimensions. The spring pins can be made either from individual, straight wire sections or from the ends of a U-shaped or W-shaped spring.

This advantageous coupling of the operating button with the bolt makes it possible to use the operating button in a completely different form on the item of clothing in question, adapted to the respective taste of the time and day. The operating button can therefore be made of metal, precious metal, plastic or organic materials such as horn, tortoise shell, mother of pearl, wood, bone or similar materials, e.g. a plastic operating button can be replaced with one made of precious metal such as gold or silver.

17.04.2003 ^Hi25953 /99

can be replaced, giving the entire garment a completely different look.

Since the male and female rings do not need to be separated from the fabric parts in order to release and replace the actuating button, they can be inseparably connected to their fabric parts, e.g. by means of a press fit or ultrasonic welding.

An embodiment of the invention is shown in the drawings.

According to Figures 1 to 3, the snap fastener connection 1 consists of a male part 2 and a female part 3. The male part 2 in turn consists of an actuating button 4 designed as a rotary knob and a pin-like extension 5 designed as a bolt 5a. The actuating button 4 is coupled to the pin-like extension 5 via the spring pins 6 and to the female part 3 via the spring pins 12. The male part 2 also includes a male upper ring 7 and a male lower ring 8, between which the upper material part 9 is clamped.

The matrix part 3 consists of a

Die upper ring 10, a die lower ring 11 and the spring pins 12 in the die lower ring 11, with the underlying material part 13 being clamped between the die upper ring 10 and the die lower ring 11. According to Fig. 3, the actuating button 4, which is designed as a rotary knob, is provided on its underside with a sleeve-like extension 4a, which has two recesses 4b on both sides of the longitudinal axis of symmetry 14 for receiving the two spring pins 6 according to Figures 1 and 2.

The male upper ring 7 is provided on its underside with a circular collar 7a into which the male lower ring 8 can be fitted with a circular projection 8a. With an appropriate selection of the tolerances of the inner diameter of the circular collar 7a and the outer diameter of the circular projection 8a, the two male rings 7, 8 can be connected to one another by means of a press fit. If the male rings 7, 8 are made of plastic, in addition to a press fit, it is also possible to connect the two rings by means of ultrasonic welding as soon as the upper material part 9 is clamped between them.

The upper die ring 10 is also provided on its underside with a circular collar 10a, into which a circular projection Ha of the lower die part 11 can be fitted. In addition, the lower die ring 11 has two diametrically opposed recesses 15 in which the spring pins 12 are held approximately parallel to one another. The word "approximately" in relation to this parallel holding of both the spring pins 6 and the spring pins 12 is intended to draw attention to the fact that an approximately parallel holding can only be present in the closed position, but does not have to be, and not in the released position, because then the spring pins 6 are convexly deformed outwards by the first truncated cone 16 or the second truncated cone 17 as the spring preload increases.

In addition, the male upper ring 7 and the male lower ring 8 have two equally large, circular openings 7b, 8b, which are penetrated with a perfect fit by the essentially circular-cylindrical bolt 5a of the pin-like extension 5. In the outer surface 18 of the first truncated cone 16, a total of six locking recesses 19 are arranged in pairs and diametrically opposite to the longitudinal axis 14.

Furthermore, in the outer surface 20 of the second truncated cone 17, six locking recesses 21 are arranged in pairs and diametrically opposite the longitudinal axis 14. Above the second truncated cone 17 there is a collar 22 which has a larger diameter than the openings 8b of the male lower ring 8 and 7b of the male upper ring 7, but a smaller diameter than the circular openings 10b in the female upper ring 10 and 11b in the female lower ring 11. As a result, the bolt 5a with the pin-like extension 5 is held between the male part 2 and the actuating button 4 according to Figures 1 and 2.

In this way, the second truncated cone 17 penetrates the opening 10b of the die upper ring and penetrates completely or partially into the opening 11b of the die lower ring 11 in order to connect the male part 2 with the female part 3 in the coupling position, the

¹⁷ · ⁰⁴ -2003 Hi 2695a/99

arranged spring pins 12 to engage with its locking recesses 21.

The male rings 7, 8 clamp the upper material part 9 between their circular ring flanges 7c, 8c, while the female rings 10, 11 hold the lower material part 13 between their circular ring flanges 10c, lic.

In Figures 9 to 16, parts corresponding to those in Figure 3 are designated by the same reference numerals, so that a further discussion of these figures is unnecessary.

The core of the invention is disclosed in Figures 4 to 8 in conjunction with Figures 17 and 18. This consists at one end of the pin-like extension 5 with the truncated cone 16 and at the other end of the bolt 5a with the second truncated cone 17. In the second truncated cone 17, a cross slot 23 is arranged in the central area near the longitudinal axis of symmetry 14 for engagement of, for example, a knife tip 26 of a knife 27, a nail file tip or a screwdriver. This cross slot-like recess 23 can also be replaced by a polygonal blind hole for engagement of a polygonal mandrel.

Furthermore, the spring pins 6, 12 do not necessarily have to have a circular diameter, but can also have a rectangular cross-section

Page 19 . . ..,*'. ,",I'".".'"I 17.04.2003

The two different cross sections of the spring pins 6, 12 during their engagement in the locking recesses 19, 21 are shown in Figures 7 and 8. As can also be seen from these Figures 7 and 8, the locking recesses 19, 21 are slightly extended in their opening area 19a, 21a, which reliably prevents the spring pins 6, 12 from accidentally disengaging, e.g. when tensile forces are exerted on the rotary knob 4, the male part 2 or the female part 3 in the direction of the longitudinal axis 14. Since in the case of rectangular cross-sections the spring pins 6, 12 engage completely in the locking recesses 19, 21 and in the case of circular cross-sections of the locking recesses 19, 21 the longitudinal axis of symmetry 24 of the spring pins 6, 12 lies slightly behind the respective lateral surfaces 18, 20 in the inner region of the truncated cones 16, 17, neither the spring pins 6 nor the spring pins 12 can be pulled out of their locking recesses 19, 21 when forces are exerted on the dies and die parts 2, 3 in the direction of the double arrow 25 of Fig. 4.

As can be seen from Fig. 18, the recesses 4b in the actuating button 4 have straight side walls 4c on their side facing the circular opening 4e for receiving the truncated cone and convexly curved side walls 4d on their side facing away from it, so that when the spring pins are spread out according to Fig. 20, they can move towards the convex walls 4d. Fig. 19 shows the

Fig. 20 shows the spring pins 6 of the actuating button 4 engaged in the locking recesses 19 of the truncated cone 16 and the disengaged position of the spring pins 6 after the actuating button 4 or the bolt 5a has been rotated by approximately 60°. 5

To replace the rotary knob 4, the female part 3 is first detached from the male part 2 as shown in Fig. 21. The tip 26 of a knife 27 or a nail file is then inserted into the cross slot 23 of the second truncated cone 17, thereby holding the bolt 5a with the two truncated cones 17, 16. In this position, the actuating knob 4 and/or the bolt 5a are rotated in one of the two directions of the double arrow 28, namely at six locking recesses 19 in the truncated cone 16 by an angle of approximately 60°, whereby the spring pins 6 are transferred from their locking position as shown in Fig. 19 to their unlocked position as shown in Fig. 20. As soon as they have reached the position of Fig. 20, the actuating button 4 with the spring pins 6 arranged in it is ejected upwards along the outer surface 18 of the truncated cone 16 in the direction of arrow 29. After this, a new actuating button 4 with the same or a different shape made of a different material or with a different appearance, but with the same spring pins 6 and the same sleeve 4a can be pressed onto the truncated cone 16 in the direction of arrow 30 until the spring pins 6 engage in its locking recesses 19. For this attachment, the knife tip 26 is no longer

17.04.2003

required, but it is sufficient if the truncated cone 16 is pressed between the thumb and the index finger of one hand in the direction of the arrow 31 of Fig. 21 or the actuating button 4 is simultaneously pressed together in the direction of the arrow 30 with the bolt 5a in the direction of the arrow 31.
