Description

Jewel with a push button

description

The invention relates to a piece of jewelry with connecting means for connecting two separable elements of a piece of jewelry and a push button as a connecting means.

For rings, brooches and other pieces of jewelry, the piece of jewelry often consists of a carrier part and a piece of jewelry attached to it. If both are designed as a fixed unit, the possible use is limited, since both the carrier part and the jewelry part must match the clothing, the current fashion or the current mood of the person wearing it. There is therefore a desire to create a piece of jewelry with separable elements in order to provide further possible combinations.

An example is the Charivari jewelry, which is particularly well known in the southern area and in which a wide variety of jewelry items, such as a framed bear tooth, a coin, etc., can be attached to a mostly heavy silver chain, but can also be detached. This can be done, for example, with closures, as are also common for connecting the ends of a chain.

However, the known connecting means have the disadvantage that they are often very difficult to handle and the elements can only be connected or detached with great skill.

Snap fasteners are known with a first element with a pin and with a second, receiving element which is provided with a spring device which, when plugged together, receives tensile forces acting in an axial direction of the pin when it is plugged together Snap connection can be brought with the pin. At opposite points on the edge of a receiving opening of the second element for receiving the pin, the spring device each has a wire-like spring section which, regardless of the angular position of the pin about its longitudinal axial direction, can be latched into a groove running around the circumferential surface of the pin . The tensile strength of the snap connection of the push button is independent of the angular position of the first element around the axial direction. Such push buttons are used in particular in very large quantities of clothing.

The object of the present invention is to provide a piece of jewelry and connecting means which are much easier to handle, maintain a reliable connection, and in particular are easy to connect or detach.

This object is achieved with a piece of jewelry with connecting means according to claim 1.

Advantageous further developments are specified in the subclaims.

A central idea of the present invention is that the connecting means comprise a receiving element and a projecting element. This ensures a certain amount of guidance when connecting. Advantageously, loosening is only possible parallel to the direction of insertion. The carrier part and the jewelry part are fixed against each other in directions perpendicular to it.

A key concept of the present invention with regard to the push button is that the pin and the spring device are designed in such a way that the holding connection which absorbs the tensile forces is dependent on an angular position about the axial direction with regard to its tensile strength is. The tensile strength of the holding connection can thus be set, for example, by simply rotating the pin about the axial direction. The rotational angle position can be set before, during and / or after the compression of the first and the second element. In a special embodiment, the angle of rotation position with the lowest tensile strength is an angle of rotation position with negative tensile strength, that is to say the first and the second element are pressed apart in this angle of rotation position. In another embodiment, in the rotational angle position with the lowest tensile strength, there is no or a positive tensile force that causes a holding connection in the axial direction.

The first and the second element preferably reach a snap connection in the rotational angle position with the greatest tensile strength when the push button is pressed together, that is to say in a connection in which the spring device snaps or snaps into place. In addition to compressing the elements at a constant angle of rotation position, a snap-in effect can also be achieved in a specific embodiment of the invention by compressing and simultaneously and / or subsequently rotating into another angle of rotation position.

When the first element is rotated relative to the second element by 90 °, the tensile strength preferably varies between a maximum and a minimum tensile strength. In particular, the maximum tensile strength is precisely at a certain (or more discrete) rotational angle position. The minimum tensile strength is then achieved by turning it exactly 90 °. Such a 90 ° rotation can be carried out particularly easily and quickly. In this case, for example, it does not have to be rotated by more than 360 ° as with some screw connections until the holding connection is released. Most people also have a natural feeling for when a turning angle of 90 ° has been reached. In addition, design the push button externally so that a rotation angle of 90 ° can be easily recognized for the user. In a particularly preferred embodiment, the rotational angle position with the minimum tensile strength is achieved from the rotational angle position with the maximum tensile strength both by turning clockwise and by turning counterclockwise. The same applies in this embodiment for turning into the rotational angle position with the greatest tensile strength.

The first and second elements are preferably designed such that a force that removes the first element from the second element acts in an ejection rotation angle position. The elements are expediently designed in such a way that when they are rotated into the ejection rotation angle position, the ejection force increases continuously in order to prevent the elements suddenly jumping apart suddenly.

In a further embodiment, the pin is tapered in the direction of its free end. The ejection force is then applied, for example, by the spring device pressing against the circumferential surface of the pin, a force component acting in the axial direction, that is to say in the ejection direction.

In a further embodiment, the pin has an at least partially circumferential groove, in particular a circumferential groove, the depth of which varies in the course of the groove in the circumferential direction of the pin between a minimum value to ensure minimum tensile strength and a maximum value to ensure maximum tensile strength. In this embodiment there is the advantage that a holding connection is still ensured even in the rotational angle position with the minimum tensile strength. In another embodiment, the groove depth in the circumferential direction of the pin varies between a minimum value and a maximum value, where however, the groove does not rotate in a closed manner, so that there is no rotational angle position with zero tensile strength or with negative tensile strength. In particular, there are two of the grooves which run around the pin along the same circumferential line and are separated from one another by a groove without a groove by two mutually opposite locations on the outer circumference of the pin.

In a further development, the maximum tensile strength of the holding connection corresponds essentially to the maximum tensile strength of the overall arrangement, that is to say the maximum tensile strength is essentially formed solely by the spring device and by the parts of the first element which interact with the spring device.

In a special embodiment, the spring device has at least one wire-like spring section, in particular the leg of a U-shaped spring clip. Furthermore, the pin has a groove arranged on its circumferential surface, into which the spring section engages in a form-fitting manner in the rotational angle position with the maximum tensile strength. The groove preferably has a substantially flat bottom surface. An embodiment is particularly preferred in which the flat bottom surface ends in the circumferential direction at an edge, so that when the first element and the second element are rotated relative to one another, the wire-like spring section has to overcome resistance when leaving the groove. The holding connection with maximum tensile strength is thus secured against unintentional twisting, for example due to vibrations. Conversely, a snap-in effect is achieved when rotating to the rotational angle position with maximum tensile strength.

In a further embodiment, the spring section of the spring device has an essentially round cross section, the depth of the groove being dimensioned such that more than half the cross section of the Tongue section is located in the groove. With this configuration, the tensile strength in the rotational angle position with the maximum tensile strength is particularly high. In particular, the maximum tensile strength corresponds to the tensile force, the application of which would lead to damage or destruction of the push button. In this case, one can speak of a locking rotational angle position.

In one development, the spring section is arranged on the edge of a receiving opening of the second element for receiving the first element. When the first element is removed, that is to say when the push button is not plugged together, the spring section protrudes into the receiving opening in the manner of a secant. Such a spring section is preferably arranged at opposite points on the edge of the receiving opening.

In a special embodiment, the second, receiving element is pot-shaped with a lower part and an attachable cover. It is then expedient for there to be at least one recess in the surface of the lower part facing the cover, in each of which the spring device is received.

With regard to the connection of pieces of jewelry to one another mentioned at the outset, it is an idea of the present invention that the connecting means comprise a receiving element and a projecting element. This ensures a certain amount of guidance when connecting. Advantageously, loosening is only possible parallel to the direction of insertion. The carrier part and the jewelry part are fixed against each other in directions perpendicular to it.

In an advantageous development, spring devices are integrated in the receiving element, which are effective in a plane perpendicular to the direction of insertion. Thereby the separable elements are also fixed positively and / or non-positively.

A snap-in connection can be defined by means of the spring devices, so that the spring ensures a snap-in connection between the separable elements of a piece of jewelry.

In a further embodiment, the projecting element comprises a groove which can be brought into operative connection with an engagement part which is provided in the receiving element. The engagement part is expediently slidably mounted in the receiving element. In a particularly expedient embodiment, the separable elements can be brought into a locking position after being brought together in the insertion direction by a relative rotation between the separable elements in an axis parallel to the insertion direction A. For this purpose, for example, the protruding element can be rotated by 90 ° after insertion and thereby come into engagement with an engagement part on the receiving element.

It is particularly advantageous if sections of the spring devices which act perpendicular to the direction of insertion act as an engagement part. In this case, the sections ensure a form-fitting, possibly additionally also a force-fitting connection between the protruding element and the receiving element.

The invention is also explained in more detail below with regard to further features and advantages based on the description of an exemplary embodiment and with reference to the accompanying drawings. However, the invention is not restricted to the exemplary embodiment shown and the use shown.

Fig. 10 is a sectional view through the lower part of FIG. 9 in a plane parallel to the direction of insertion. 1 shows an embodiment of connecting means for a piece of jewelry in an exploded perspective view obliquely from above. The connecting means comprise a protruding element 12 and, in the present case, a multi-part receiving element 11. The receiving element 11 comprises a lower part 20 and a cover 21. Corresponding openings 25, 24 are provided in the cover 21 and in the lower part 20, into which a rotationally symmetrical pin 18 of the protruding element can be inserted. The shape of the opening 25 in the cover 21 is expediently dimensioned such that the rotationally symmetrical pin 18 of the projecting element 12 is held therein in a form-fitting manner.

In the lower part 20 of the receiving element 11, on which the cover 21 is normally attached, there are recesses 22, 23 on the upper side facing the cover 21, which are formed here as essentially rectangular pockets with rounded corners. In these recesses 22, 23, spring devices 13, 14 can be used, which in the present case are designed as U-shaped spring clips. The recesses 22, 23, which can be milled, for example, reach the opening 24 to such an extent that the recesses 22, 23 and the opening 24 are designed to be coherent. So stick out of both

Sides of the spring devices in each case into the opening 24 of the lower part 20. The part of the spring devices protruding into the opening 24 is formed by a section 16, 17 of the spring clips 13, 14. This section 16, 17 is located on the leg of the U-shaped spring clip 13, 14 facing the opening 24.

The spring clips 13, 14 are each inserted into the recesses 22, 23 in such a way that the open ends of the spring clips are oriented in the opposite direction in plan view or, viewed in the circumferential direction, are respectively aligned to the right or left. In the shown in Fig. 1 Embodiment, both spring clips 13, 14 are oriented to the right when viewed in the circumferential direction.

The sections 16, 17 of the spring clips 13, 14 are arranged such that they engage in the locking position in grooves 15, 15 'on the rotationally symmetrical pin 18 of the projecting element (cf. FIG. 2).

In FIG. 2, the receiving element 11 and the protruding element 12 from FIG. 1 are shown obliquely from below in a perspective exploded view.

The rotationally symmetrical pin 18 of the protruding element 12 allows a targeted insertion into the receiving part formed from the cover 21 and the lower part 20

Element 11. The cover 21 is essentially cylindrical and comprises a cover plate 26, a circumferential curve 27 and a circumferential surface 28. The inner radius of the circumferential surface 28 is slightly larger than the outer diameter of the lower part 20, so that the cover 21 on the Lower part 20 is attachable. The curve 27 is rounded between the cover disk 26 provided with the opening 25 and the lateral surface 28. This prevents sharp edges in the receiving element 11.

3 shows a carrier element 29, which in the present case is designed as a ring. The carrier element has a recess 30 designed for inserting the receiving element 11, which is worked into the outer surface of the ring 29 radially from the outside, for example milled. The receiving element 11 can be fastened in the recess 30 of the ring 29, preferably by welding, soldering or gluing.

4 and 5, the protruding element is again in two sectional views, one parallel to the insertion direction A and one perpendicular to the insertion direction. device A shown. In this embodiment, the grooves 15, 15 ′ are worked into the lateral surface of the rotationally symmetrical pin 18 from two opposite sides. It therefore has two mutually parallel, rectilinear floor surfaces 30, 31, such that the groove or grooves 15 have their greatest depth at two radially opposite positions of the pin.

The projecting element 12 with the rotationally symmetrical pin 18 can be clipped into the receiving element 11 by inserting it in the direction of insertion A with the base surfaces 30, 31 parallel to the sections 16, 17 of the spring clips (snap-in connection).

Alternatively, the projecting element 12 can be placed in a rotationally offset position on the receiving element 11 and inserted into it. The spring clips 13, 14 are compressed and initially remain in this state. When the protruding element 12 rotates in the receiving element 11, a locking position can be reached in which the spring clips 13, 14 immerse as far as possible in the grooves 15, 15 'or support the reaching of the locking position when the protruding element is rotated.

As an alternative to the described embodiment of the groove or the grooves 15, 15 ', a circumferential groove can also be formed on the rotationally symmetrical pin 18, which reaches its greatest depth at two radial positions objected to by 180 ° and, on the other hand, offset their smallest depth by 90 °. As a result, a snap-in connection can be achieved immediately in any rotational position of the projecting element 12 when it is inserted into the receiving element 11. After turning into the locking position, this locking, which may be referred to as pre-engagement, may become an actually positive locking. To form a positive lock The corresponding sections 16, 17 of the spring clips 13, 14 must be immersed in the groove 15 with more than half their cross-section, so that the spring clips 13, 14 are prevented from sliding out under forces counter to the insertion direction A.

FIGS. 6 and 7 show sectional views of the receiving element 11 and the projecting element 12 in the locked state. From Fig. 6 it can be seen how the shapes of the protruding element 12 are coordinated with the rotationally symmetrical pin of the cover 21 and the lower part 20. So the opening 24 in the lower part 20 is also tapered and adapted to the rotationally symmetrical pin 18 from the radius and cone angle.

Of the spring clips 13, 14 only the sections 16, 17 are shown which engage in the groove 15. 7 shows the spring clips 13, 14 with a solid line in the locking position, in which the sections 16, 17 bear against the bottom surfaces 30, 31 of the groove 15 under a certain prestress. The spring clips 13, 14 are shown in broken lines in a further relaxed state. The spring clips 13, 14 assume this state when the receiving element 11 is completely isolated from the projecting element 12 (open state of the connecting means).

Also shown in dashed lines is a further compressed state of the spring clips 13, 14, which is assumed when the spring clips are compressed by the outer surface of the rotationally symmetrical pin in a rotational position of the pin, in which they cannot dip into the groove 15.

These maximum deformations of the spring clips 13, 14 are shown again schematically in FIG. 8. In Fig. 9, the lower part 20 is shown in plan view and in Fig. 10 in section. In the view shown in FIG. 9, the shape of the recesses 22, 23 for the spring clips 13, 14 and their interaction with the opening 24 is illustrated again.

With the connecting means described above, depending on the depth and design of the groove or the grooves in the circumferential direction and the spring force of the spring clip, a connection that is dominated by a force fit or a form fit can be created. In addition, the connection can be designed as a snap-in connection in the direction of insertion or as a rotary lock. Of course, different mixed forms are possible.
