Definitions
- the invention relates to a shackle lock, in particular for a two-wheeler, for example a bicycle or a motorcycle, which has a lock body and a shackle, the shackle being able to be brought into an open position or into a closed position, in which the shackle can be locked on the lock body.
- Such a padlock is used, for example, to secure a two-wheeler against unauthorized driving away, for example by the bracket being guided through a spoked wheel of the two-wheeler.
- a padlock can be used to fix a two-wheeler to a stationary object, for example to a lamp post.
- such a padlock can be used to secure an object against unauthorized use or unauthorized access, with the padlock being brought into the closed position and locked.
- the authorized user on the other hand, can selectively bring the shackle into the open position, in which the shackle is open relative to the lock body or is completely detached from the lock body.
- Out of DE 100 26 701 A1 such a padlock with a mechanical locking cylinder is known.
- Out of DE 10 2018 111 302 A1 such a padlock with an electrically driven locking device is known.
- the bracket may have a generally U-shape, as is generally the case DE 299 03 865 U1 , U.S. 5,417,092 A , U.S. 5,488,845 A , WO 94/10414 A1 , DE 10 2018 116 434 A1 or EU-Design EM 002113266-0002 (though without the tapered or pointed ones shown in some of these documents temple ends).
- the shackle in question here can also have a rectilinear shape, as is generally the case for padlocks, for example WO 2006/109299 A2 or EP 2 333 204 A1 , or for brake disc locks in general DE 10 2005 043 926 A1 , or for frame locks in general DE 103 58 300 A1 or DE 10 2004 052 463 A1 , or for scaffolding locks in general WO 2015/185380 A1 is known.
- bracket under discussion here can also be designed in several parts, in particular with several links connected to one another in an articulated manner, for example as an articulated rod lock, as is generally the case EP 0 638 473 B1 , EP 0 675 995 B1 or EP 0 689 987 B1 is known.
- Such a shackle lock should be as secure as possible against burglary, in particular against attacks on the shackle by sawing (ie cutting with a geometrically defined cutting edge) or pinching.
- Attacks by accumulator-powered angle grinders also known as angle grinders or flex
- cuttings with a geometrically undefined cutting edge have increased in recent years.
- the U-lock includes a lock body and a shackle.
- the lock body has at least one insertion opening, in particular on an outside, which opens into an insertion channel.
- the lock body also has a locking device.
- the shackle can be selectively brought into an open position or into a closed position relative to the lock body.
- the bracket has at least one end of the bracket, which in the closed position of the bracket can be inserted through the respective insertion opening into the associated insertion channel of the Lock body protrudes. In the closed position, the shackle can be locked by the locking device on the lock body.
- the bracket has a metal tube with a cavity extending in a longitudinal direction of the tube. In this cavity there is a reinforcement filling, which has granules embedded in a binding material.
- the shackle end(s) has at least one respective locking structure for locking engagement of the locking device of the lock body.
- the respective locking structure is formed on an outside of the tube without forming an opening to the lumen of the tube.
- the shackle lock includes a shackle that can optionally engage in a lock body with one or more end(s).
- the shackle In this closed position of the shackle, the shackle can be locked by means of a locking device arranged in the lock body and thus secured against unauthorized opening or complete detachment from the lock body.
- the shackle and the lock body can thus form a closed loop, for example.
- the shackle can be unlocked and subsequently opened or detached from the lock body by authorized actuation of the locking device, for example by means of a physical identification means or a code.
- the bracket includes a tube with a lumen extending generally in a longitudinal direction of the tube.
- the cavity can extend continuously over the entire length of the bracket, although interruptions can also be provided, in particular an interruption in a central section of the bracket.
- a reinforcement filling which has granules, ie a large number of particles of a first material, and a binder, ie a second material which fixes the particles.
- the reinforcing fill need not fill the entire lumen of the tube, but may be recessed relative to the end(s) of the tube and/or have discrete voids (but preferably smaller than the inner diameter of the tube).
- At least one end of the shackle has at least one respective latching structure (e.g., a dimple) adapted to selectively latchingly engage a portion or member of the latch body latch to latch the shackle to the latch body.
- the respective locking structure is formed on an outside of the tube of the bracket and can, for example, have a round shape (eg spherical segment) or an elongated shape (eg transverse slot or web).
- the respective locking structure can have a locking depression, or a locking elevation (eg bulge), or a combination of locking depression and locking elevation.
- the respective locking structure can extend along only part of the circumference of the pipe or along the entire circumference of the pipe (eg as an annular groove or annular bead).
- the respective locking structure can in particular be introduced into the tube by machining (eg by milling) or by non-machining (eg by stamping).
- the wall thickness of the tube and the respective locking structure are coordinated in such a way that the locking structure does not form an opening to the cavity of the tube, i.e. no passage to the interior of the tube, but the respective locking structure is closed executed.
- the tube is thus also closed circumferentially at the level of the respective locking structure.
- a padlock of this type is characterized by a high level of security against forced entry with regard to the possible use of force on the padlock.
- the tube of the bracket is made of metal, for example steel, and can therefore have a toughness that is characteristic of metal materials. As a result, the bracket has a high tensile strength. This makes spreading or pinching attacks particularly difficult. If an attempt is made to tear the shackle out of the lock body, for example in the case of a U-bolt using an expanding tool which acts parallel to the legs of the U-shape, high tensile forces are transmitted to the locking device which is in the lock body with the locking structure of the shackle is engaged.
- this interface between the shackle and the lock body has a high level of stability, since the respective locking structure on the outside of the tube of the shackle is designed as a closed structure, i.e. in the case of a locking recess as a pure recess (in the manner of a blind hole), without a To form opening to the cavity of the tube (ie in the manner of an opening).
- This uninterrupted design of the pipe at the respective locking structure avoids or at least minimizes a weakening of the pipe in that area in which particularly high tensile forces are exerted on the pipe in the event of the attempted break-in.
- the reinforcement filling inside the bracket with the granules it contains can also provide a high level of protection against sawing and grinding, since particles can be used to form the granules which - in contrast to the metal of the pipe - are more brittle, but also have higher hardness. This makes it particularly difficult to attack by sawing or grinding, for example using an angle grinder.
- This additional sawing and grinding protection due to the reinforcement filling takes place at least in that section of the shackle which is exposed in the closed position of the shackle, ie does not protrude into the lock body. In fact, in the closed position of the bracket, the reinforcement panel extends from the exposed one Section of the shackle at least up to the level of the insertion opening(s) of the lock body.
- the reinforcement filling can extend in the cavity of the tube, starting from a portion of the bracket that is exposed in the closed position, at least up to the level of the at least one locking structure of the bracket or of the tube. This can contribute to greater stability of the hanger.
- the reinforcement filling can also extend beyond the respective locking structure. However, it is not necessary for the reinforcement filling to extend to the respective end of the tube of the bracket and, for example, to be flush with the tube end. This is because the protection against sawing and grinding provided by the reinforcement filling is not required inside the lock body.
- the reinforcement filling can extend continuously in the hollow space of the tube between the insertion openings of the lock body when the shackle is in the closed position. This provides complete protection against sawing and grinding due to the reinforcement filling.
- the respective end of the bracket provided with the locking structure can be formed at the level of the locking structure without an additional reinforcement element in the cavity of the tube, ie without an insert or the like. This simplifies the manufacture of the brackets. Due to the high tensile strength of the tube due to the closed design of the locking structure(s), such a reinforcement element is not required. However, caps can be provided at the respective end of the bracket, which do not have a reinforcing function but, for example, prevent dirt from entering the cavity of the tube, exclude the risk of injury on the edges of the tube ends or are intended to fulfill a decorative function. In alternative embodiments, however, such an additional reinforcement element can be arranged in the cavity of the tube at the level of the respective locking structure.
- the tube of the bracket may be formed from hardened or self-hardening steel. This achieves a particularly high degree of hardness and strength.
- the tube of the bracket can have a circular, oval or polygonal cross section, in particular a square, hexagonal or oblong cross section.
- the wall thickness of the tube of the bracket is selected in such a way that the respective locking structure does not form an opening to the cavity of the tube.
- the cavity of the tube should have a certain diameter (clear width) so that the reinforcement filling has a sufficient number and a sufficient degree of coverage of the particles of the granulate.
- the tube of the bracket has a wall thickness which is at least a quarter, in particular at least a third, of the outer diameter of the tube.
- this information relates to the minimum outside diameter of the pipe, e.g. in the case of a square cross-section of the pipe to the edge length of the square (and not to the diagonal).
- the inner diameter of the tube at some embodiments have a value that is at most half or at most one third of the outside diameter of the tube.
- the lumen of the tube may extend to the at least one shackle end of the shackle. This can simplify the manufacture of the tube and the filling of the reinforcement filling in the cavity of the tube is made possible. Alternatively or additionally, the cavity of the tube can extend over the entire length of the bracket.
- the tube of the bracket may have a constant outer diameter and/or a constant wall thickness and/or a constant inner diameter over the entire length of the bracket.
- the outer diameter of the tube of the bracket can have a value in the range of 12 mm to 18 mm (e.g. approx. 16 mm) in the case of a circular cross-section or a value in the range of 10 mm to 16 mm in the case of a square cross-section (for example approx. 13 mm).
- a value in the range of 12 mm to 18 mm e.g. approx. 16 mm
- a value in the range of 10 mm to 16 mm in the case of a square cross-section (for example approx. 13 mm).
- other outer diameters and geometries are also possible.
- the granules of the reinforcement filling can be hard metal particles (e.g. with tungsten carbide, titanium carbide or titanium nitride) and/or ceramic particles (e.g. with aluminum oxide or silicon nitride). In this way, a high level of protection against sawing and grinding can be achieved.
- hard metal particles e.g. with tungsten carbide, titanium carbide or titanium nitride
- ceramic particles e.g. with aluminum oxide or silicon nitride.
- the particles of the granulate may be irregularly shaped and/or have sharp edges.
- the particles can be in the form of chips.
- the particles may be chaotically (i.e. unsystematically) arranged and oriented within the reinforcement fill.
- the particles can be dimensioned and shaped in such a way that in the cavity of the tube, there is an overlap of a plurality of particles arranged one behind the other essentially along all possible viewing axes.
- the granules can have a grain size in the range from 0.5 mm to 5 mm, in particular in the range from 1.5 mm to 2.5 mm, this value preferably being chosen depending on the inside diameter of the tube of the bracket .
- the inner diameter of the tube can be larger than the granulation size by a factor in the range of 2 to 3 times. In this way, a degree of coverage of particles in the granulate can be achieved that provides a high level of protection against sawing and grinding, without the individual particles being so small in relation to the inside width of the cavity of the tube that they could pass a saw blade as a result of lateral deflection make possible.
- the bonding material of the reinforcement fill may include a solder, particularly a metallic solder.
- a solder particularly a metallic solder.
- the granules of the reinforcement filling in particular a large number of particles that Form granules and which are embedded in the solder
- an integral connection at the atomic or molecular level
- a solder simplifies the production of a U-bolt, for example when straightening the U-bolt.
- a metallic solder can dissipate the heat generated in this way to the entire bracket (in particular the metal tube) so that the stationary fixation of the granulate of the reinforcement filling is retained, since the solder is prevented from melting due to the heat dissipation .
- a metal-binding soft solder, hard solder or also pure metal can be provided as the solder.
- the inside boundary surface of the cavity of the pipe at least in the area of the reinforcement filling, can have a roughened or drawn surface.
- a roughened or drawn surface has the advantage of increasing the overall surface area, which allows the reinforcement filling to bond better to the pipe.
- the locking device of the lock body can have at least one movable bolt, wherein the shackle can be locked to the lock body in the closed position by moving the respective bolt to a locking position in which the bolt makes a locking engagement with the respective locking structure of the tube enters
- the locking device can be purely mechanical, for example with a key-operated lock cylinder.
- the locking device may be electromechanical, for example with an electronic lock cylinder, electric motor or an electromagnet that drives the bolt or bolts.
- the yoke may be formed as a U-yoke, with the tube of the yoke being generally U-shaped.
- a U-bolt can have a variety of forms, as is known from the documents mentioned at the outset.
- a U-bracket can have two legs, which can be connected to one another, in particular, by a connecting section.
- a round transition can be provided between the two legs of the U-shape, although in general an angular transition can also be present.
- the two legs of the U-shape can be aligned parallel to one another or at an acute angle.
- the two legs of the U-shape can form two shackle ends, with the two shackle ends preferably being aligned parallel to one another in order to enable both shackle ends to be inserted into associated insertion channels of the lock body. If only one of the two shackle ends has one or more locking structure(s), the other shackle end can, for example, have a hanging section for hanging the U-bolt on the lock body, as is known from the documents mentioned at the outset (e.g WO 94/10414 A1 ).
- the lock body of the padlock may have an elongated shape, such as a circular, oval, or rectangular cross-section.
- the longitudinal shape can in particular be aligned perpendicularly to the longitudinal axis of a U-bolt.
- the bracket and the tube can be designed at least essentially in a straight line, as is known from the documents mentioned at the outset.
- the locking structure can be provided at one end of such a straight bracket and, for example, a thickening can be provided at the other end, which allows mobility of the bracket limited.
- the bracket can be made in several parts, as is known from the documents mentioned at the outset, with a corresponding number of tubes being provided which are provided with the reinforcing filling, for example in the case of an articulated rod lock.

- a reinforcement filling 51 which has a granulate 53 which is embedded in a binding material 55 .
- the granulate 53 comprises a multiplicity of irregularly shaped particles, in particular particles of higher hardness than those of the tube 35, for example from hard metal or ceramic.
- the binding material 55 comprises a solder, for example a metallic solder.
- the U-bracket 31 has at each of its two bracket ends 33 a respective locking structure in the form of a locking recess 39 which is formed on an outer side of the tube 35 .
- the reinforcement filling 51 extends approximately to the height of the locking depressions 39.
- the locking depressions 39 are designed as closed depressions, i.e. they do not form a continuous opening to the cavity 37 of the tube 35.
- the U-bolt 31 can be removed from the lock body 11 in an unlocked position of the bolt 21 (not shown) (open position). If, on the other hand, the U-bolt 31 assumes the closed position and the bolts 21 of the locking device 17 are in the respective locking position, as is shown in 1 is shown, the U-bolt 31 is locked on the lock body 11 .
- the bolts 21 engage in the respective locking recess 39 of the U-bolt 31 or the tube 35 and thus block the U-bolt 31 against removal from the lock body 11.
- the U-lock shown is characterized by a high level of security against burglary. Because the tube 35 of the U-bolt 31 is made of metal, the U-bolt 31 has a high tensile strength. In the case of the U-bolt 31 shown, this tensile strength is not significantly weakened by the locking indentations 39 of the tube 35 since the locking indentations 39 do not form through openings but are formed entirely within the wall of the tube 35 . At the same time, the reinforcement filling 51 in the cavity 37 of the tube 35 provides a high level of protection against sawing and grinding due to the granules 53 contained therein.
- locking depressions 39 can also be designed as annular grooves.
- locking elevations e.g. webs
- combinations of locking depressions 39 and locking elevations can also be provided, which can be formed, for example, by stamping. If a locking elevation is attached by punching, the tube 35 (e.g. wall thickness) and the punching process (e.g. tool, immersion depth, direction, force) are coordinated in such a way that the locking elevation in its surroundings does not form an opening to the cavity 37 of the tube 35.
- a differently curved bracket or a straight bracket can also be provided, and/or the bracket can be designed in several parts, as is generally known from the documents mentioned at the outset.
- the geometry of the end of the bracket 33, the locking structure or locking recess 39 and the bolt 21 cooperating therewith can in such embodiments be similar to the area A according to FIG 1 be trained.
