[0062] FIG. 12 a perspective representation of the locking bar of the jointed bar hoop.

[0063] FIG. 1 shows a perspective representation of a portable hoop lock that is configured as a joint lock 11 and that has a lock body 13 and a jointed bar hoop 17 connected thereto. The jointed bar hoop 17 comprises a plurality of jointed bars 20 composed of metal that are pivotably connected to one another and that are connected at their ends by rivets 81 to the respective adjacent jointed bars 20. In this respect, a first end 79 of the jointed bar hoop 17 is permanently fastened to the lock body 13, while a second end of the jointed bar hoop 17 is formed by a locking section 21 of a so-called locking bar that, in the representation shown, is introduced into an introduction passage 57 of the lock body 13 and may be selectively locked to the lock body 13 or released therefrom.

[0064] To be able to comfortably handle the joint lock 11, it has an outer cover 83 that surrounds the lock body 13. This outer cover 83 may in particular be produced from a plastic to enable a pleasant gripping and holding of the joint lock 11 during the operation. Similarly, the jointed bars 20 and the locking section 21 also have respective jackets 18 composed of plastic. In addition to a more improved and more pleasant handling, in particular on a pivoting of the jointed bars 20 with respect to one another to form a loop and to secure an object, a noise formation by an abutting of the jointed bars 20 or of the locking section 21 may also be counteracted by these jackets 18.

[0065] In the representation shown, the jointed bar hoop 17 is placed in a so-called yardstick configuration in which the longitudinal axes A of the flat jointed bars 20 and of the locking section 21 (locking bar) are aligned in parallel with one another. In this configuration, the joint lock 11 may in particular be conveniently and compactly stowed during a transport.

[0066] The embodiment shown here of a portable hoop lock as a joint lock 11 merely serves for illustration while other embodiments may also be provided. For example, the hoop lock may also be configured as a U hoop lock having a rigid and substantially U-shaped hoop, or as a wire hoop lock having a wire rope hoop, or as a chain lock having a chain hoop.

[0067] FIG. 2 shows a cross-section through the joint lock 11 perspectively shown in FIG. 1. In FIG. 3, this cross-sectional representation is shown enlarged in the region of the lock body 13. As may be seen therefrom, the joint lock 11 has an electromechanical locking mechanism 15 centrally arranged in the interior of the lock body 13. This locking mechanism 15 comprises an electric motor 23 that is configured to selectively move a latch 19 into a release position or into a locking position via a drive transmission section 25 by a rotation about the axis of rotation D. While the release position of the latch 19 makes it possible to axially introduce the locking section 21 with respect to its longitudinal axis A into the introduction passage 57 of the lock body 13, the locking section 21 completely introduced into the lock body 13 may be securely locked to the lock body 13 by a transfer of the latch 19 into the locking position.

[0068] To reliably position the electric motor 23 in the interior of the lock body 13, the electric motor 23 is arranged on a carrier section 44 of a carrier 39. Furthermore, the carrier 39 has a connection section 43 that extends perpendicular to the carrier section 44 and that has a connection opening 33 within whose peripheral boundary 37 the drive transmission section 25 of the latch 19 is supported.

[0069] As may, for example, be seen from FIGS. 8A to 8C, the carrier 39 surrounds the locking mechanism 15 and is correspondingly configured as an inner housing of the joint lock 11. In this respect, the inner housing formed by the carrier 39 is, however, not completely closed, but is cage-like and, in addition to the connection opening 33, has further openings that may, for example, facilitate the insertion of the locking mechanism during an assembly of the joint lock 11.

[0070] To protect the electrical components of the electromechanical locking mechanism 15 and in particular the electric motor 23 against damage by liquid entering into the interior of the lock body 13 or by contamination, the carrier 39 is surrounded by a watertight cover 27 that is in particular elastically deformable and that may, for example, be formed from a plastic such as silicone (cf., in addition to FIGS. 2 and 3, also FIGS. 5, 6, 7A, 7B, and 10). In addition to the electric motor 23 supported by the carrier section 44 of the carrier 39, an electrical energy source 71 is further arranged within the cover 27 and provides the energy necessary for supplying the electromechanical locking mechanism. To enable a charging of this energy source 71, which is configured as an accumulator by way of example, the cover 27 has a watertight charging socket 73 such that an entry of liquid into the interior of the cover 27 through this opening, which is necessary for the permanent provision of electrical energy, may be reliably prevented.

[0071] The cover 27 further surrounds a loudspeaker 75 which is part of an alarm device not shown further and by means of which, on a detection of a break-open attempt, an acoustic signal may be transmitted through a sound exit opening 76 to alert a user or other persons in the environment to the break-open attempt. To protect the interior of the cover 27 against liquids such as rainwater possibly entering through the sound exit opening 76 or against contamination, the loudspeaker 75 may have a watertight membrane such that the sound exit opening 76 may also be sealed in a water-impermeable manner.

[0072] Furthermore, a radio module 77 is arranged within the cover 27 and may in particular be configured for a wireless reception of control commands for the electric motor 23. For this purpose, a user may, for example, transmit a command to the radio module 77 via a mobile radio connection, via a WiFi/WLAN connection, or via a Bluetooth connection, whereupon the electric motor 23 may in response to this command move the latch 19 into the desired position by a rotation about its axis of rotation D.

[0073] Furthermore, the radio module 77 may be configured to transmit information on the joint lock 11 to a user and may, for example, notify the user when the locking section 21 is securely locked to the lock body 13. Furthermore, provision may be made to transmit an alarm generated by an alarm device not only acoustically via the loudspeaker 75, but also via the radio module 77. A user who is not in the environment of the joint lock 11 may thereby also be informed of such attempts and may initiate or perform the necessary measures to preserve the object secured by the joint lock 11.

[0074] A sensor 67, which is likewise surrounded by the cover (cf. also FIGS. 8A and 8B), is arranged at the carrier 39. This sensor 67 is arranged at a section of the carrier 39 that is laterally offset with respect to the end of the introduction passage 57 of the lock body 13. The sensor 67 is configured to detect an introduction of the locking section 21 of the jointed bar hoop 17 into the introduction passage 57. To actuate the sensor 67, an actuation element 69, which is configured as a rocker, is arranged within the last part of the path which the locking section 21 of the jointed bar hoop 17 describes during an introduction. This actuation element 69 may be driven by the introduced locking section 21 to perform an actuation movement in the form of a tilting in order to mechanically contact the sensor 67 in the end position of the locking section 21 in which said locking section 21 may be locked to the lock body 13 by the latch 19.

[0075] To enable this mechanical contact, the sensor 67 is surrounded by a deformable section 28 of the cover 27 that is elastically deformed on a contact by the actuation element 69 and that exerts a force detectable by the sensor 67 onto the sensor 67 (cf. also FIGS. 5 and 7A). On a detection of the introduced locking section 21, the sensor 67 may, for example, transmit a corresponding detection signal to a control device, not shown, that may then, in particular automatically, control the locking mechanism 15 or the electric motor 23 to move the latch 19 into the locking position. Thus, a user may only completely introduce the locking section 21 into the introduction passage 57 of the lock body 13, whereupon it is automatically locked to the lock body 13 without further measures of the user being necessary. Since the cover 27 is arranged within the cover 27, the sensor 67 is also protected against water or contamination.

[0076] Due to the provision of a watertight charging socket 73 and a loudspeaker 75 having a water-impermeable membrane sealing the sound exit opening 76, the risk of an entry of liquid or contamination through one of these openings may be counteracted. Since it is, however, necessary to lock the locking section 21 of the jointed bar hoop 17 introduced into the lock body 13 outside the cover 27, the cover 27 furthermore has a cover opening 29 aligned with the connection opening 33 of the connection section 43 of the carrier 39. This enables a projection of the latch 19, which is driven by the electric motor 23, into the introduction passage 57 of the lock body 13 to be able to enter into engagement with the introduced locking section 21 of the jointed bar hoop 17 there and to be able to lock it.

[0077] To also seal the cover opening 29, the cover 27 has a clamping section 41 that peripherally surrounds the cover opening 29 and that contacts an outer side of the connection section 43 of the carrier 39 (cf. also FIGS. 7A, 8A, 8C, and 10). To connect this clamping section 41 in a water-impermeable manner to the carrier 39, the clamping section 41 of the cover 27 is clamped between the connection section 43 of the carrier 39 and a counter connection section 45 of the lock body 13.

[0078] The clamping section 41 of the cover 27 is in this respect fixedly clamped between the connection section 43 of the carrier 39 and the counter connection section 45 of the lock body 13 in that the counter connection section 45 of the lock body 13, which is also shown in FIGS. 11A and 11B, is fixedly connected to the connection section 43 of the carrier 39 by means of four screws 54 and in particular by means of a fixing element 53 that is likewise configured as a screw. Due to this fixed connection of the connection section 43 to the counter connection section 45, the clamping section 41 of the cover 27 is clamped in the gap (clamping gap 49) forming between the connection section 43 and the counter connection section 45 and is pressed via a sealing edge 42 formed at the connection section 43 (cf. also FIGS. 8A and 8C). The clamping gap 49 may thus be closed in an at least substantially water-impermeable manner by the clamping section 41, wherein the clamping section 41 of the cover 27 may in particular be elastically formed and may be compressed in the clamping gap 49 by the pressing against the connection section 43.

[0079] The counter connection section 45 of the lock body 13 further has a counter connection opening 47 that is aligned with the cover opening 29 and the connection opening 43 and whose peripheral boundary 51 supports the drive transmission section 25 of the latch 19. It may in particular be achieved by this support of the latch 19 that the latch 19 is arranged in a clearly defined position and projects into the introduction passage 57 to enable an introduction of the locking section 21 in the release position and to lock it securely in the locking position. Furthermore, the counter connection section 45 of the lock body 13 peripherally surrounds the introduced locking section 21 with respect to its longitudinal axis A such that the cage-like counter connection section 45 forms a boundary of the introduction passage 57 (cf. also FIGS. 5, 11A, and 11B). Due to this boundary, attempts may in particular be counteracted to remove the introduced and locked locking section 21 from the latch 19 and thereby to release it from the lock body 13 in an unauthorized manner.

[0080] As will further be seen from FIGS. 2 and 3, in addition to the connection of the counter connection section 45 to the connection section 43 of the carrier 39, the fixing element 53 also serves to fix the carrier 39 and the counter connection section 45 to a housing 55 of the joint lock 11 and thereby to be fixedly arranged therein. In this respect, the housing 55 may in particular be produced from metal and may, for example, be produced as a cast part that primarily serves to protect the components arranged within it against damage by a force effect during a break-open attempt (cf. also FIG. 4). Since parts of the locking mechanism 15 and in particular the electric motor 23 are supported by the carrier section 44 of the carrier 39, it may also be achieved by the fixing of the carrier 39 within the housing 55 that the locking mechanism 15 is positioned fixed within the housing 55 in a reliable manner and fastened to the housing.

[0081] Due to the water-impermeable closing of the clamping gap 49 by a clamping of the clamping section 41 of the cover 27 between the connection section 43 of the carrier 39 and the counter connection section 45 of the lock body 13, a possible penetration of water into the interior of the cover may be reliably prevented at this point. Thus, only the mutually aligned openings in the connection section 43, in the cover 27, and in the counter connection section 45, which are necessary for an exit of the latch 19 from the interior of the cover 27 and for the support of said latch 19, thus remain as a potential possibility for an entry of liquid into the interior of the cover 27.

[0082] To also close this entry into the interior of the cover 27 in a water-impermeable manner, two sealing elements 35 configured as sealing rings are arranged between the drive transmission section 25 of the latch 19 and the peripheral boundary 37 of the connection opening 33 such that the connection opening 33 is closed in a substantially water-impermeable manner by the drive transmission section 25 of the latch 19 and the two sealing elements 35 (cf. also FIGS. 8A, 8C, 9, and 10). Due to the design of the sealing elements 35 as O-rings, they are adapted to the rotational movement about the axis of rotation D performed by the latch 19 between the release position and the locking position. A permanent sealing of the connection opening 33 may hereby be achieved in both latch positions and during the movement of the latch 19.

[0083] While only the connection openings 33 are sealed by sealing elements 35 in the embodiment example shown here, provision may equally be made to arrange sealing elements 35 between the latch 19 and the peripheral boundary 51 of the counter connection opening 47 and thereby to seal the latter. In general, as is the case here, only the connection opening 33, alternatively thereto only the counter connection opening 47, or both openings 33 and 47 may be sealed in a water-impermeable manner. Likewise, differently configured sealing elements may also be provided that may, for example, be adapted to a latch that may be transferred from the locking position into the release position by a translational movement. Furthermore, it is possible to connect the cover 27 to the connection section 43 of the carrier 39 in a manner other than that shown here and to adhesively bond the cover 27 thereto in a watertight manner, for example. Accordingly, in particular the connection section 43 arranged within the cover 27 may act as a support section and its connection opening 33 may act as a support opening through which the drive transmission section 25 projects in a sealed manner.

[0084] Furthermore, provision may also be made to arrange a latch 19, which is provided for a selective locking of an introduced locking section, completely outside the cover 27 and to provide the drive transmission section 25 as a transmission element that is separate from the latch 19 and that is configured to transmit a drive power generated by the electric motor 23 within the cover 27 to the latch 19 arranged outside the cover 27.

[0085] FIGS. 4 to 12 show further perspective representations of components of the joint lock 11 to further illustrate this embodiment example.

[0086] FIG. 4 shows a perspective representation of the joint lock 11 with an outer cover 83 removed. The housing 55, to which the first end 79 of the jointed bar hoop 17 is permanently connected by means of the associated rivet 81, is arranged within said outer cover 83. Furthermore, the locking section 21 forming the second end of the jointed bar hoop 17 is introduced into the introduction passage 57 of the lock body 13 extending into the interior of the housing 55.

[0087] As FIG. 5 shows, the locking section 21 introduced axially with respect to its longitudinal axis A into the introduction passage 57 is peripherally enclosed with respect to this axis A by the counter connection section 45 that is in particular connected to the cover 27 by the fixing element 53 (cf. also FIGS. 11A and 11B). Due to this boundary of the introduction passage 57 by the counter connection section 45, the introduced locking section 21 may be secured against external access and against a moving away from the latch 19 projecting into the introduction passage 57.

[0088] Furthermore, FIG. 5 shows the arrangement of the actuation element 69, configured as a rocker, at the counter connection element 45 within the path described by the locking section 21 during an introduction into the introduction passage 57 such that, on a complete introduction of the locking section 21, the actuation element 69 may be tilted and brought into contact with the elastically deformable section 28 of the cover 27 by said locking section 21. Due to the deformation of this section 28, the sensor 67 arranged beneath this section 28 in the interior of the cover 27 may be actuated to be able to detect the introduction of the locking section 21 (cf. also FIG. 2 and FIG. 3).

[0089] As may be seen from FIG. 6, the latch 19, which may be moved from the release position shown into a locking position through a rotational movement by 90° about the axis of rotation D, also projects, and thus projects permanently, into the introduction passage 57 and the path of the introduced locking section 21 in the release position (cf. also FIG. 8A). Accordingly, the release position and the locking position only differ by the rotational position of the latch 19.

[0090] To lock the locking section 21 introduced into the lock body 13 through the mentioned rotation by 90° about the axis of rotation D, the latch 19 shown in the release position in FIG. 9 has an elongate engagement section 59 having an effective length and an effective width. In the release position, the effective length of the latch faces in the direction of the longitudinal axis A of the introduced locking section 21 that may be axially introduced with respect to its longitudinal axis into the lock body 13 (cf. also FIGS. 1, 2, 3, 4, 5, and 12).

[0091] To be able to introduce the locking section 21 shown in FIG. 12 into the introduction passage 57 of the lock body 13 even though the latch 19 projects into the path described by the locking section 21 during the introduction, the locking section 21 has a passage channel 61 that is open at a first end 63 and whose width exceeds the effective width of the engagement section 59. Through this passage channel 61, the engagement section 59 may be guided into a latch receiver 65, into which the passage channel 61 leads, in the release position of the latch 19 during an introduction of the locking section 21 into the introduction passage 57. The design of the latch receiver 65 with a clear width that is larger than the effective length of the engagement section 59 makes it possible to rotate the latch 19 and correspondingly the engagement section 59 of the latch 19 by 90° within the latch receiver 65 and to transfer the latch 19 into the locking position. In the locking position, the engagement section 59 is secured against escaping into the passage channel 61 of the locking section 21 such that the locking section 21 is locked to the lock body 13 by the engagement of the latch 19 into the latch receiver 65.

[0092] FIGS. 7A and 7B show perspective representations of the cover 27 that has the watertight charging socket 73 at a rear end and the sound exit opening 76 at a lower side. At its front end, the cover 27 has the cover opening 19 that is peripherally surrounded by the clamping section 41.

[0093] FIGS. 8A to 8C show perspective representations of the carrier 39 within which the locking mechanism 15 is at least partly arranged and which is enclosed by the cover 27 (cf. also FIG. 10). As FIG. 8C shows, the connection section 43 of the carrier 39 is arranged at the side facing the cover opening 29 and has the connection opening 33 at whose peripheral boundary 37 the drive connection section 25 formed in one part with the latch 19 is supported.

[0094] The carrier 39 and the elements of the locking mechanism 15 supported by its carrier section 44 are arranged within the cover 28 (cf. FIG. 10). To connect the clamping section 41 of the cover 27 to the connection section 43 of the carrier 39 in a water-impermeable manner, the counter connection section 45 of the lock body 13 shown in FIGS. 11A and 11B is connected to the carrier 39 by means of the screws 54 and the fixing element 53 configured as a screw. In this respect, the clamping section 41 is compressed in the clamping gap 49.

[0095] In order also to close the connection opening 33 (cf. FIG. 8C) in a watertight manner, the sealing elements 35 are provided (cf. FIG. 9). The connection opening 33 is closed and sealed in a water-impermeable manner by the drive transmission section 25 of the latch 19 and the two sealing elements 35 such that an entry of water into the interior of the cover 27 through the connection opening 33 may be counteracted.
