Definitions

  • the invention relates to a lock, in particular a bicycle lock or padlock, with a lock body which comprises a lock housing and has a locking element receptacle, a locking element which can be brought into a closed state in which it is inserted into the locking element receptacle with a locking section, and a locking mechanism which is accommodated in the lock housing and is designed to selectively lock the locking element in its closed state against leaving the locking element receptacle or to release it for leaving the locking element receptacle.
  • Such a lock can be used in particular to secure a movable object to a fixed object.
  • the locking element in the closed state, optionally together with the lock body, forms a ring-shaped closed structure.
  • the locking element can be guided through an opening in the movable object (e.g. the struts of a two-wheeler and/or the spokes of a wheel of a two-wheeler) and around the fixed object (e.g. a lamppost) or through an opening in the fixed object (e.g. a fence or a two-wheeler stand) in order to secure the movable object to the fixed object.
  • the closed state can be secured by the locking mechanism and that the ring-shaped closed structure can only be opened optionally by means of the locking mechanism and in particular only with knowledge or possession of a locking secret (e.g. a key, a code or a biometric feature).
  • a locking secret e.g. a key, a code or a biometric feature
  • the lock housing in which the locking element is at least partially accommodated and in which the locking mechanism interacts with the locking element.
  • the lock housing in order to assemble the locking mechanism and, if necessary, other components of the lock, the lock housing must first be open. In order to replace components, for example due to wear and tear, or to reconfigure the lock, it can also be useful if the lock housing can still be opened, preferably easily, after assembly. The aim is therefore for the lock housing to be able to be locked in a particularly reliable manner and then secured against unauthorised opening, but in principle can also be opened again easily by an authorised person.
  • the lock according to the invention comprises: a lock body which comprises a lock housing and has at least one locking element receptacle; a locking element which can be brought into a closed state in which it is inserted with a locking section into the locking element receptacle; and a locking mechanism which is at least partially accommodated in the lock housing and is designed to selectively lock the locking element in its closed state against leaving the locking element receptacle or to release it for leaving the locking element receptacle.
  • the locking element when the locking element is in the closed state, i.e. when the locking element is in its closed state and the locking section is inserted into the locking element receptacle, it is possible to select whether the locking section is locked in the locking element receptacle or whether it is released by operating the locking mechanism. In this way, the locking section of the locking element can be reliably locked to the lock body, but can also be released from the lock body again.
  • the locking mechanism can comprise a latch that is adjustable between a locking position and an unlocking position, wherein the latch is designed to interact with the locking section of the locking element in the locking position, provided the locking element is in the closed state (for example by engaging in a locking structure of the locking section and/or by engaging behind a locking structure of the locking section) and thereby block it from leaving the locking element receptacle, but in the unlocking position to release the locking section for leaving the locking element receptacle.
  • the locking structure of the locking section can, for example, comprise an engagement recess (e.g. opening, blind hole, groove).
  • the latch can then be adjusted between the locking position and the unlocking position (or at least from the locking position to the unlocking position) in particular by means of an actuation of the locking mechanism.
  • the locking mechanism can thus be used to adjust the latch so that the locking section of the locking element is blocked from leaving the locking element holder or is released for leaving the locking element holder.
  • the locking mechanism is preferably protected from unauthorized operation by a locking secret. It can be mechanical, mechatronic or electronic.
  • the locking mechanism can comprise a locking cylinder that can only be operated using a key assigned to the locking cylinder. In this case, the locking secret is therefore formed by the key.
  • a numerical code, a cryptographic key, an electronic signal and/or a biometric feature can also be considered as a locking secret.
  • the locking element can in particular have an elongated shape that extends from a first end to a second end of a longitudinal extension of the locking element (straight or curved; rigid or flexible).
  • the locking element can be designed as a rigid bracket, wire rope (cable), chain, rod or articulated rod arrangement.
  • the locking section mentioned can in particular be provided at one of the ends of the longitudinal extension mentioned, for example in the form of a block.
  • the lock can (as already explained) serve in particular to secure a movable object to a fixed object.
  • the lock can advantageously have a ring-shaped closed structure in the closed state of the locking element.
  • the ring-shaped closed structure can be formed by the locking element together with the lock housing, for example if an end of the longitudinal extension of the locking element opposite the locking section is permanently attached to the lock body or in a similar way to the locking section can be locked to the lock body.
  • the ring-shaped closed structure may be formed only by the locking element, for example if the locking element has an eyelet, in particular at an end of its longitudinal extension opposite the locking section, through which the locking section can be threaded in order to form a loop as a ring-shaped closed structure before the locking section is then locked to the lock body.
  • a ring-shaped closed structure is not absolutely necessary; for example, the locking element can comprise a single (in particular elongated) block.
  • the lock housing comprises a pot element with a base and a peripheral wall protruding from the base, as well as a cover element closing the pot element.
  • the material of the pot element and the cover element can each be a metal, preferably a hardened metal.
  • the cover element can be designed, for example, as a cover sheet, in particular as a stamped and bent part.
  • the pot element and the cover element can each also comprise a plastic, a ceramic or a combination of these materials.
  • the pot element and the lid element are each preferably formed integrally as one piece, in particular from metal.
  • An integrally formed one piece means that the pot element or the lid element is originally formed as a single materially bonded part, which can be produced, for example, by casting and subsequently formed.
  • Such a pot element or lid element therefore differs in particular from elements that are assembled from two or more parts and whose individual components are connected to form a detachable or permanent joint, such as by welding or screwing.
  • the lock housing preferably consists exclusively of the cup element and the cover element.
  • the pot element can be formed in particular by deep drawing or casting (for example plastic injection molding or ceramic casting). In principle, production by means of a firing process is also possible.
  • the pot element can be designed as a deep-drawn sheet metal part.
  • the pot element preferably has a collar reinforcement.
  • the base of the pot element is preferably at least substantially flat.
  • the base can in particular have an at least substantially rectangular shape.
  • the base can also have a round or oval shape. It is also conceivable that the base is uneven, for example convexly curved.
  • the wall mentioned can protrude, in whole or in part, at least essentially perpendicularly from the floor.
  • the transition between the floor and the wall can be designed as an edge, whereby the edge does not necessarily have to be square, but can also be rounded. In principle, a smooth transition between the floor and the wall is also conceivable, especially if the floor is curved.
  • the wall can further comprise several, in particular four, wall sections, each of which is preferably at least substantially flat. Adjacent wall sections can meet along corners of the wall, in particular at least substantially perpendicularly, and can preferably be connected to one another, in particular in a materially bonded manner. Like the transitions to the base of the pot element mentioned, these corners can also be rounded.
  • an interior of the pot element which is also an interior of the lock housing, can be delimited in two of three mutually perpendicular spatial directions on both sides by the wall, namely in particular by a respective one of the said wall sections, and in the third spatial direction delimited on one side by the floor, but open in the opposite direction (i.e. not delimited by the pot element).
  • the cover element or at least one cover section of the cover element delimits the interior on this open side, the cover element can close the pot element.
  • the pot element can be at least essentially cuboid-shaped, with one side of the cuboid shape being formed by the base of the pot element and the four adjacent sides of the cuboid shape being formed by the wall, namely in particular by a respective one of the four wall sections of the pot element.
  • the cover element or at least one cover section of the cover element can then be arranged in accordance with the remaining side of the cuboid shape and thereby close the pot element.
  • other shapes for the pot element and the cover element are also possible. In principle, the pot element and the cover element could also be shaped such that the lock housing is spherical.
  • the pot element has at least one first through-opening through which the locking section of the locking element can be inserted into the locking element receptacle in order to bring the locking element into the closed state.
  • the base of the pot element preferably has the first through-opening.
  • the first through-opening can also be formed, entirely or at least partially, in the wall of the pot element.
  • the locking section of the locking element can be inserted into the locking element receptacle in particular from the outside, i.e. from outside the lock body, through the first through-opening.
  • the first through-opening can be closed around the circumference, i.e. delimited by a continuous, circumferential edge.
  • the first through-opening is preferably open towards the interior of the lock body or the pot element.
  • the designation of the said through opening as the first through opening does not imply that the pot element necessarily has one or more further through openings, and it is also not to be understood in the sense of a hierarchy between possibly several through openings, but merely serves to be able to conceptually distinguish between possibly several through openings of the pot element.
  • the first through-opening forms an entrance to the locking element receptacle and can therefore be considered part of the locking element receptacle.
  • the locking section of the locking element can only be inserted into the locking element receptacle through the first through-opening. It is preferred if the first through-opening is closed all the way around, i.e. is delimited by a continuous, circumferential edge.
  • the pot element has at least one engagement section.
  • the engagement section can be formed in particular by an edge section of the first through-opening or by an edge section of an engagement recess (e.g. depression, opening) separate from the first through-opening.
  • the engagement section can extend in a straight line, in particular as an edge at which two flat surfaces meet.
  • the engagement section can be designed, for example, as a locking edge.
  • an edge surface of the first through-opening or of an engagement recess separate therefrom can meet a surface of the pot element.
  • this edge surface and the surface of the pot element meet at an at least substantially right angle or at an acute angle.
  • the cover element has a cover portion and at least one first leg protruding from the cover portion.
  • the lid section can in particular be flat and is preferably essentially flat. In principle, however, the lid element can also be uneven, for example convexly curved.
  • the shape of the lid section can (with regard to its cross section perpendicular to the spatial direction with respect to which the base and the lid section are arranged opposite to one another and preferably aligned vertically) at least essentially correspond to the shape of the base of the pot element; in this respect, the shape can in particular be at least essentially rectangular, although other shapes, for example a round or oval shape, can also be considered.
  • the pot element can thus be closed by the lid section of the lid element.
  • a sealing closure i.e., openings, gaps or the like can remain between the lid element and the pot element, for example, which be functional or can result from manufacturing technology.
  • openings can also be desired for ventilation or drainage.
  • the boundary of the surrounding wall of the pot element facing away from the bottom of the pot element can form a receptacle for the lid element and can extend in particular within a plane (preferably parallel to the bottom of the pot element).
  • the cover element preferably consists exclusively of the cover portion, the first leg and optionally one or more further legs protruding from the cover portion.
  • the leg or legs of the cover element can in particular be elongated and/or have a fastening projection at a free end, as will be explained below.
  • the first leg and optionally present further legs can protrude from the cover section in particular at least substantially perpendicularly.
  • the leg or legs of the cover element can be aligned in particular orthogonal to an extension plane of the cover section.
  • the first leg of the cover element engages behind the engagement section of the pot element.
  • the engagement is such that the cover element is secured to the pot element.
  • the cover element can in this way (especially due to the engagement) be positively locked against being removed from the pot element in a direction pointing away from the floor (in particular perpendicular to the floor).
  • the cover element is only accessible via the first leg and optionally one or more, in particular fundamentally similar, further legs. (such as the second leg described below) to the pot element. This means that in such an embodiment there are no additional fastening means for securing the lid element to the pot element.
  • the lock housing By securing the cover element to the pot element, the lock housing is also secured in a locked state.
  • the design and assembly of the lock housing are comparatively simple; at the same time, the interior of the lock body is reliably protected from external access by the lock housing.
  • the engagement section of the pot element by the first leg of the lid element can be engaged behind the engagement section by a spring-back design of the first leg. For example, when the lid element is connected to the pot element, the first leg of the lid element can latch onto the engagement section of the pot element.
  • the engagement section of the pot element by the first leg of the lid element can also be engaged behind the engagement section by plastic deformation of the first leg.
  • leg does not imply that the cover element necessarily has one or more further legs, and it is also not to be understood in the sense of a hierarchy between possibly several legs, but merely serves to be able to conceptually distinguish between possibly several legs of the cover element.
  • the first through hole of the pot member may be formed at the bottom of the pot member.
  • the engagement portion of the pot element may be formed by an edge portion of the first through-opening, wherein the first leg of the lid element extends through the first through-opening of the pot element in order to engage behind the engagement portion or the edge portion of the first through-opening.
  • the locking section of the closing element (in its closed position) and the first leg of the lid element essentially completely fill the first through-opening of the pot element.
  • the locking section of the closing element can block the first leg of the lid element against detachment from the engagement section or the edge section of the first through-opening.
  • the peripheral wall of the pot element can have at least one first engagement recess, wherein the first leg of the cover element engages in the first engagement recess, and wherein the engagement section of the pot element is formed by an edge section of the first engagement recess.
  • the first leg of the cover element does not necessarily have to reach as far as the first through-opening of the pot element and in particular not as far as the bottom of the pot element.
  • the first leg of the detector element can - in relation to its longitudinal extent - interact with the engagement section of the pot element, in particular in the lateral direction.
  • the bottom of the pot element can have at least one first engagement recess, wherein the first leg of the cover element engages in the first engaging recess, and wherein the engaging portion of the pot element is formed by an edge portion of the first engaging recess.
  • the first engagement recess can in particular be formed by a free space that is recessed from its surroundings so that the free space can be accessed.
  • the first engagement recess can be, for example, a depression, a groove, a blind hole or a through-opening in the base and/or in the wall of the pot element. It is preferred if the first engagement recess is closed on its circumference, i.e. is delimited by a continuous peripheral edge.
  • the first engagement recess is preferably open (at least) towards the said interior of the lock body or the pot element; in the case of a through-opening, it is open on both sides (both inwards and outwards).
  • the said engagement section can be provided on an edge of the first engagement recess and can in particular be designed as a latching edge. If the wall of the pot element has the engagement recess, an inner surface (i.e. a surface facing the said interior of the lock housing or the pot element) of the pot element and an edge surface of the first engagement recess preferably meet at the engagement section. If, on the other hand, the base has the engagement recess, an outer surface (i.e. a surface facing away from the said interior) of the pot element and an edge surface of the first engagement recess preferably meet at the engagement section.
  • the designation of the aforementioned engagement recess as the first engagement recess does not imply that the pot element necessarily has one or more further engagement recesses, and it is also not to be understood in the sense of a hierarchy between possibly several engagement recesses, but merely serves to be able to conceptually distinguish between possibly several engagement recesses of the pot element.
  • the pot element can have a plurality of first engagement recesses of the type mentioned, each of which has an engagement section, so that the first leg of the cover element can selectively engage in one of the plurality of first engagement recesses and engage behind one of their engagement sections.
  • the first engagement recesses can in particular be arranged in such a way that the size of the lock housing can be adjusted by selecting a respective one of the engagement recesses.
  • the cover section of the cover element can be arranged at different distances from the base of the pot element, depending on which of the first engagement recesses the first leg engages in or which of the first engagement recesses the first leg engages behind.
  • the plurality of first engagement recesses can be arranged one behind the other with respect to an assembly direction of the cover element and/or at different distances from the base of the pot element.
  • the first leg of the cover element preferably extends from the inside, i.e. from within the lock body (in particular from the aforementioned interior of the lock housing or the pot element), at least partially through the first through-opening or into the first engagement recess.
  • the first leg extends only through a part of the first through-opening.
  • the first leg extends through the first through-opening, in particular outwards, i.e. to an outside of the pot element (in particular from the aforementioned interior of the lock housing or pot element).
  • the first leg can engage behind an edge of the first through-opening of the pot element, for example by engaging in a latching receptacle formed on the edge at least substantially perpendicular to the direction in which it extends through the first through-opening.
  • the engagement section can then be formed by an edge that delimits this locking receptacle.
  • a locking receptacle does not necessarily have to be provided.
  • the first leg can also engage behind the edge of the first through-opening by resting against an outer side of the pot element, in particular the base of the pot element, for example with a fastening projection (described below).

  • the locking element in the closed position i.e. when the locking section of the locking element is inserted into the locking element receptacle of the lock body, can essentially fill the first through-opening of the pot element in such a way that the locking element blocks access to the first leg of the cover element through the first through-opening. This can prevent a tool from being inserted through the first through-opening into the lock body in the event of a manipulation attempt in order to release the first leg of the cover element from the engagement section of the pot element and thus be able to remove the cover element from the pot element.
  • the locking portion of the closing element and the first leg of the lid element can together substantially completely fill the first through-opening of the pot element.
  • the locking section of the closing element inserted into the closing element receptacle can block the first leg of the lid element against detachment from the engagement section.
  • This blocking effect can - with respect to the longitudinal extent of the first leg - take place in particular in the lateral direction. What is meant by this blocking effect is that the locking section of the closing element makes it impossible for the first leg of the lid element to detach from the engagement section of the pot element due to its spatial arrangement.
  • the first leg of the lid element can be blocked in that the locking section, when inserted into the closing element receptacle, takes up a space into which the first leg of the lid element would have to be moved in order to move away from the engagement section of the pot element (and thus no longer engage behind the engagement section).
  • the cover element is simultaneously secured to the pot element. This securing occurs automatically when the locking section of the locking element is inserted into the locking element receptacle and is therefore advantageously always present when the locking element is in the closed state.
  • the locking portion of the locking element inserted into the locking element receptacle is arranged directly adjacent to the first leg of the cover element in such a way that the locking portion and the first leg overlap one another when viewed in the transverse direction (ie perpendicular to the longitudinal extension of the first leg).
  • the first leg of the cover element can be blocked particularly reliably by the locking section against detachment from the engagement section and leaving the first through-opening.
  • the locking section and the first leg completely fill the first through-opening (at least in the direction in which the first leg would have to be moved for detachment).
  • the first leg of the lid element can be elastically deflected in such a way that, when the closing element receptacle is free, it can be released from the engagement section of the pot element against a restoring force (in particular only against a restoring force), i.e. can be guided past the engagement section.
  • a restoring force in particular only against a restoring force
  • the first leg can indeed be moved away from the engagement section of the first engagement recess in such a way that it no longer engages behind the engagement section and can consequently be removed from the first through-opening or the first engagement recess.
  • the aforementioned restoring force must be overcome, which advantageously prevents the first leg from engaging behind the engagement section from being released too easily or even on its own.
  • the elastic deflectability of the first leg can also enable the cover element to be easily released from the pot element and thus the lock housing to be easily opened. Whether the lock housing can be opened depends on whether the lock is locked: as long as the locking element is in its closed state, the lock housing is secured against opening by the locking element; if, on the other hand, the locking element receptacle is free, the cover element (at least insofar as it is attached to the pot element via the first leg) can be released from the pot element.
  • the first leg engages behind the engagement section of the pot element, it can basically be in a rest position with regard to its elastic deflectability.
  • the first leg can also be prestressed, in particular by the aforementioned restoring force, against the engagement section of the pot element, in particular against an edge of the first through-opening or the first engagement recess.
  • the first leg presses permanently against the engagement section, which on the one hand makes the attachment of the cover element to the pot element even more reliable and on the other hand contributes to a firm fit of the components of the lock housing, which can prevent the components from rattling.
  • the first leg has a fastening projection at an end of its longitudinal extension remote from the cover section, which protrudes transversely to the longitudinal extension of the first leg.
  • the first leg can then advantageously be designed to connect the engagement section of the pot element with the
  • the fastening projection can protrude from the first leg in particular perpendicular to the longitudinal extension of the first leg and thus in particular parallel to the cover section of the cover element.
  • the fastening projection can also be designed as a locking projection.
  • the fastening projection can be designed as a bevel.
  • a bevel can be formed in particular by simply bending the said end of the first leg, which simplifies the manufacture of the cover element.
  • the first leg rests against a first wall section of the wall of the pot element.
  • the first leg of the lid element and the said first wall section of the wall of the pot element are in direct contact with one another along an interface.
  • the first leg can be guided through the first wall section when the lid element is attached to the pot element and can also be supported on the wall section after attachment. This also prevents the interior of the pot element from being significantly restricted by the first leg.
  • the engagement section of the pot element is formed by an edge section of the first through-opening
  • the engagement section can be formed in particular on that edge section of the first through-opening which delimits the first through-opening in the direction in which the first wall section is aligned. If the first leg has the aforementioned fastening projection, the latter can protrude from the first leg in particular in this same direction.
  • the pot element can have a further engagement section, wherein the cover element has a second leg protruding from the cover section, which engages behind the further engagement section of the pot element in order to secure the cover element to the pot element. This securing is then in addition to the securing of the lid element to the pot element, which is effected by the first leg and its engagement behind the associated engagement section.
  • the further engagement section of the pot element can be designed at least substantially as described above.
  • the further engagement section of the pot element can be formed, for example, by an edge section of a second through-opening of the pot element, in particular on its base, or by an edge section of a second engagement recess of the pot element, in particular on its wall.

  • the second leg can be blocked against detachment from the further engagement section and exiting the second through-opening, for example, by the further locking section taking up a space within the second through-opening into which the second leg would have to be moved in order to detach from the further engagement section and exit the second through-opening.
  • the further locking section and the second leg completely fill the second through-opening (at least in the direction in which the second leg would have to be moved for detachment).
  • the second leg does not necessarily have to be connected to a further locking element receptacle. Rather, it can also be prevented in other ways that the second leg can become detached from the further engagement section.
  • the pot element in particular the base of the pot element, has a second through-opening, but without it being provided that a further locking section of the locking element can be inserted through the second through-opening into a further locking element receptacle of the lock body; rather, in this case, the second through-opening (optionally in addition to the second leg extending through it, so that the leg can engage behind an engagement section formed on an edge of the second through-opening) serves to enable a securing element, which can be designed as a securing plate, for example, to be inserted into the lock body, advantageously in such a way that it blocks the second leg from becoming detached from the further engagement section.
  • a securing element can be held in the lock body, preferably in a captive manner, in particular in a force-fitting and/or form-fitting manner, e.g. by latching onto a structure of the lock body or by caulking.
  • the engagement of the further engagement section can primarily serve to initially secure the cover element to the pot element during assembly before the permanent connection is made.

  • the locking mechanism is arranged at least largely inside the lock housing in order to be protected against manipulation from the outside.
  • the opening mentioned enables the locking mechanism to be operated from the outside. So that no access to the interior of the lock housing is possible through the opening, the opening is preferably completely filled by the locking mechanism, whether the locking mechanism extends up to the opening or the locking mechanism extends through the opening.
