Definitions

  • the invention relates to a combination lock, in particular for two-wheelers, with a lock body and a clamp, which are permanently connected to each other via a flexible connecting device - such as a cable, a spiral cable, an armored cable, a chain or the like -, wherein the lock body has a numerical locking mechanism wherein the block comprises a block body and a crown mandrel having a plurality of lateral engagement recesses, and wherein the ball mandrel is insertable into the lock body to cooperate there with the numerical locking mechanism.
  • a flexible connecting device - such as a cable, a spiral cable, an armored cable, a chain or the like -
  • the lock body has a numerical locking mechanism
  • the block comprises a block body and a crown mandrel having a plurality of lateral engagement recesses, and wherein the ball mandrel is insertable into the lock body to cooperate there with the numerical locking mechanism.
  • Combination locks in which the block and the lock body are each made of cast material, such as zinc diecasting material, are basically known.
  • the crown mandrel is formed as a cylindrical journal on which a comb is usually formed, which has the engagement recesses.
  • the security against break-ups of such combination locks is limited.
  • the invention has for its object to provide a combination lock of the type mentioned, which ensures increased security against breakage, especially a high breaking load.
  • the crown mandrel is not formed integrally with the block body as a casting or injection molded part, but rather as a separate sheet metal part.
  • a sheet metal part is to understand a flat, rolled metal part.
  • the sheet metal part may have a rectangular cross section in a normal plane to the longitudinal axis of the ball mandrel.
  • the sheet metal part may have an aspect ratio in cross section, i. a thickness to height ratio of 1: 2 or less, more preferably 1: 3 or less, the height being calculated to the bottoms of the engagement recesses.
  • the block body is preferably made of cast material or injection molding material.
  • the Klobendorn made of sheet metal has over a manufactured of cast material Klobendorn increased security against breakage, as a sheet metal part has a higher breaking load than a cast part. This can be attributed in particular to the higher ductility of sheet metal compared to casting material. Sheet metal is under the action of external forces, especially in a Aufbruch Eat, slightly plastically deformable, but there is no or only at high load to break even at high loads. It is particularly preferred if the chunking mandrel is formed as a sheet steel part, since a steel sheet has a particularly high ductility.
  • a receiving sleeve of the lock body in which the crown mandrel is received in an inserted position, solid and thus more stable than in known combination locks with a cross-sectionally substantially round mandrel, since less space is required by a slender sheet metal part as for the Picking up a massive cylindrical pin made of cast material. Because the Receiving sleeve is also charged in a break-open attempt, this can be further increased the security against break-up.
  • a formed as a sheet metal part Klobendorn is also easy to manufacture and with little effort to connect with the block body.
  • the crown mandrel is profiled in the longitudinal direction.
  • the profiling may in particular be such that the crown mandrel is formed substantially V-shaped in the longitudinal direction.
  • An S-shaped profile is possible, for example.
  • the crown mandrel or sheet metal part is formed as a stamped sheet metal part, i. made by punching.
  • the engagement recesses of the crown mandrel can be produced in an advantageously simple manner at the same time.
  • the plunger has a bore, via which the plunger is attached to the block body, preferably pinned or screwed or riveted.
  • the crown mandrel may also be guided by a continuous slot formed in the block body and bent at its end guided through.
  • the lock body comprises a receiving sleeve on which a plurality of locking rings of the numerical locking mechanism are rotatably mounted, wherein the Klobendorn is positively received in an inserted position in the receiving sleeve, wherein between the Klobendorn and surrounding the Klobendorn receiving sleeve preferably an air gap remains ,
  • a particularly stable connection between the clamp body and the lock body can be achieved.
  • the in Fig. 1 shown clamp 11 of an otherwise not shown combination lock comprises a made of a cast material clamp body 13 and a separately formed from the clod body 13 Klobendorn 15, wherein the Klobendorn 15 in Fig. 2 again and shown in enlarged form.
  • the crown mandrel 15 is inserted into a slot formed in the block body 13 and secured by a pin 21 which is inserted through a through the block body 13 and the mandrel 15 extending bore to secure the mandrel 15 permanently on the block body 13.
  • the crown mandrel 15 is made of sheet steel and manufactured by punching.
  • the crown mandrel 15 is profiled in the longitudinal direction to form a V-shaped recess 25, in particular in Fig. 2a is recognizable.
  • the crown mandrel 15 comprises an integrally formed comb 23, which has a plurality of lateral engagement recesses 17.
  • the lip mandrel 15 has without profiling or before it is profiled in a normal plane to its longitudinal axis a rectangular cross section with an aspect ratio, ie a ratio of height h to thickness d, for example, 1: 3, wherein the height h to the floors the engagement recesses 17 is calculated.
  • a lock body with a known number-lock mechanism and a flexible connection means such as a spiral cable, an armored cable or a chain over which the lock body and the clamp 11 are permanently connected.
  • the lock body comprises a receiving sleeve, which surrounds the profiled outline of the crown mandrel 15 in a form-fitting manner, wherein a plurality of locking rings of the number locking mechanism are rotatably mounted on the receiving sleeve.
  • the locking rings engage in the engagement recesses 17 of the introduced Klobendorns 15, so that the clamp 11 is locked to the lock body, whereas in an unlocking position, ie in a certain combination of numbers, the locking rings are oriented such that the comb 23rd of the crown mandrel 15 pass through formed in the locking rings radial recesses can, so that the clamp 11 and the lock body are unlocked, each locking ring has exactly one radial recess.
