Definitions

  • the present invention relates to a jewelry lock according to the preamble of independent claim 1 and a method for closing jewelry, such as from the GB Patent 1,035,064 is known.
  • Closure devices for jewelry are known. width Bayonet locks are widely used in the utility model DE Gm 76 01 893 described type Closure devices in particular allow one and the same Jewelry chain with different, decoratively designed To use closures.
  • a closure is known with which a wear associated with the kinking of the chain at the lock should be prevented.
  • the connector holder by means of a tilting bearing with an oval cross-section on this suitably shaped closure can be accommodated.
  • the object of the present invention is a to create improved jewelry lock.
  • the locking plug receptacle according to claim 1 with the bayonet-type connector attached to it the one that is taken when locking and secured against turning first position without further assistance from the wearer the movements of the chain on the clasp caused by wear axially move the acting low forces and slide axially freely into the positions in which twisting the plug connector is possible. So lies in Use a flat closure piece flat at any time, without fear of blocking its rotation.
  • the closure of the invention is without can also be used with existing chains. It can also very thin chains like pearl or thin chains Gold chains are used without this having a minimum volume must have; use with thicker and therefore relatively rigid chains without the risk of wear and tear Bending of parts of the closure through the full page Enclosing the locking plug receptacle allows.
  • the usage a small sleeve for gripping the locking plug holder ensures that the external dimensions of the invention Jewelery clasp only slightly larger than with conventional bayonet locks.
  • This "floating Storage” is particularly desirable and is available with gap sizes of less than 2/10 mm, gap sizes preferably less than 5/100 mm and particularly preferably 2.5 / 100 mm, while the lock connector itself a length of a few Can have millimeters. It is preferred if the stroke, i.e. the immersion depth around which the locking plug receptacle yourself from the position range of the closure piece with free Rotation to the position secured against twisting in the Jack moves, also in the range of less than a millimeter lies. In a practical embodiment, so the same external dimensions as with common locking arrangements can be achieved according to the prior art.
  • the socket in a practical version has an outer diameter of between 3 and 5 mm have what their problem-free Installation in beads, for example. It has proven to be beneficial proven if to achieve the small gap sizes the facing surfaces of the socket and plug connector generated by high-gloss turning.
  • the low friction provided by the gap ensures even if the arrangement is free from wear Carrier of the chain while wearing the clasp plays and rotates it permanently.
  • the the smooth rotatability even stimulates such play on.
  • the wearer is irritated by standing up the lock is excluded when twisting the chain. On in this way the wearing comfort is increased.
  • a piece of jewelry closure 1 includes at least one outside essentially cylindrical locking plug receptacle 2, which is designed to receive a locking plug 3, which on its side facing away from the jewelry clasp 1 can be connected with a chain 4 or the like or about penetrated in a known manner by a string of pearls is.
  • grooves 5 are provided, which in the Use with projections 6a, 6b on the connector facing Side (reference number 7a on the double arrow A) of the locking plug receptacle 2 are arranged.
  • Compression spring 9 on a plate 10 facing the plug, and presses them on the inside in the idle state of projections 6a, 6b and optionally an annular one Border around the cavity 8.
  • the spring 9 On the opposite side (Reference number 7b on the double arrow) the spring 9 is supported an annular border.
  • the locking plug receptacle 2 is in a socket 11 with at least essentially slidable hollow cylindrical interior and generally arranged concentrically and by a projection 12 on the side of the socket facing the plug (7a) 11 and opposite the socket bottom 16 held captive.
  • the length of the bushing 11 compared to the length of the Lock plug receptacle 2 and thus the stroke by which the Lock plug receptacle 2 along the double arrow A in the Socket 11 can be moved is in the drawing for reasons the clarity of what is required in practice Exaggerated measure. It is sufficient if the socket 11 only is little longer than the locking plug receptacle 2, which in practice has a length measurement in the millimeter range.
  • the locking connector receptacle 2 faces the connector 3 facing away (direction 7b) a recess 14 in which when positioning the locking plug receptacle 2 in a first position close to or directly on the socket bottom 16 (as shown in FIGS. 1 and 2a), one provided there corresponding increase 15 in positive and / or frictional Intervention can occur.
  • the locking plug receptacle 2 Unless the locking plug receptacle 2 is not in the first Position close to or directly on the socket bottom 16, but away from it in any other axial position (Fig. 2b), which is in the stroke range, the locking plug receptacle turn freely in the socket.
  • a gap 13 is provided, which is not to scale Drawing is shown exaggerated. In practice it is by the difference between the outer diameter of the plug connector 2 and clear width of the socket 11 formed Gap 13 very small; Gap sizes below half Millimeters are easy to manufacture, are preferred Gap sizes under 2/10 mm and a particularly favorable storage behavior results in gap sizes below 5/100 mm, preferred 2.5 / 100mm. With a sufficiently precise production is a smooth rotation of the locking plug receptacle 2 in the bushing 11 enables the ball bearing-like turning properties guaranteed. The for the small gap sizes mentioned required manufacturing precision can in particular by high-gloss turning of the parts on standard machines be achieved.
  • the jewelry clasp according to the invention is closed, by the plug 3 past the projections 12 of the socket 11 is pressed onto the locking plug receptacle and the grooves 5 brought into alignment with the projections 6a, 6b.
  • the Tip 3a of plug 3 is then in contact with the plate 10 pressed, which prevents jamming with the spring 9.
  • the Pressing causes a movement of the locking plug receptacle 2 inside the socket 11 and leads to seating of the locking plug receptacle on the socket bottom 16, recess 14 and increase 15 if necessary by a slight rotary movement engage at connector 3.
  • the breech's own gravity, Restoring forces of a somewhat rigid chain or the light ones Movements of the chain wearer are sufficient for this.
  • the locking plug receptacle 2 can then be freely inside turn the socket 11 with the plug connected.
  • FIG. 3b and Fig. 4 Another exemplary embodiment of the invention is shown in FIG. 3b and Fig. 4 using largely the same reference numerals shown.
  • This is another embodiment with the previously described in design and function largely identical, but shows a difference in terms the captive holder of the locking plug receptacle 2 in that instead of the projections 12 on the Socket 11 of the socket interior near the socket bottom 16 a all around running stage 12a, which acts as a stop for a the locking plug receptacle 2 preferably all around Shoulder 17 serves near the socket bottom. Between the inner wall of the socket and the shoulder 17 runs a gap 13 ', the preferably how gap 13 is dimensioned.
  • FIG. 3a The corresponding top view for the embodiments according to FIG. 1 is shown in Fig. 3a, the top view of Fig. 2c in Fig. 3b.
  • Fig. 4 shows an exploded view of a socket 11 for the Embodiment according to Fig. 2c, which is not in one piece from a massive workpiece is made, but from a graduated Pipe piece 18 and a separate bottom insert 19 assembled is.
  • the surfaces 18a and 19a can be used for assembly by means of gluing, press fitting, spot welding or another known methods are connected.
  • Fig. 5 shows an embodiment in which in a double socket 11a two locking plug receptacles 2a, 2b on back Back are arranged.
  • the socket bottom instead could have a recess into which a facing Elevation of the locking plug receptacle can intervene. Also could have a partial area on both sides as a recess and be designed as a survey.
  • the locking plug receptacle 2 instead of a generally cylindrical outer shape, the locking plug receptacle 2 also generally conical become. If the inside of the socket has the same cone angle provided, arises when the locking plug receptacle is pressed in a desired friction fit into the socket.
