Description

ELECTRONIC FRAME LOCK WITH DETACHABLE CHAIN BOLT

Field of the invention

The invention relates to an electronic frame lock for locking a wheel for a mode of transport to the frame, with a detachable chain for securing the mode of transport to an external object.

Background to the invention

Known frame locks block the rotational movement of one of the wheels of the mode of transport (e.g. bicycle) by locking the rim of the wheel to a frame. A frame lock typically comprises a ring bolt having a substantially circular segment-shaped configuration. The ring bolt can be brought in a closed position and a release (opened) position. Through operation of a lock mechanism the ring bolt can be released to be brought in the opened position. Further, the known lock is provided with a detachable chain bolt opening in which a chain bolt of a chain cable can be inserted, so that the ring lock can be fastened to an external object such as, a fence, a tree or a post. The detachable chain bolt is typically provided with a circumferential groove into which a fixing element of the frame lock can be engaged. When the fixing element has been brought in the unlocking position, the fixing element has been moved out of the cable pin opening and hence also out of the circumferential groove of the chain bolt, so that the chain bolt can be taken out of the cable pin opening of the lock.

An electronic frame lock dispenses with mechanical key. The lock is controlled by radio signals, for instance, from a radio-frequency identification (RFID) tag, and/or via a cellular network. In the art, movement of the ring bolt between the closed position and release positions may be motorised. US2018118294 and EP 2357124 A2, for example, describe electro-mechanically driven frame locks. A problem in the art is the complexity and power consumption of a wireless electronic frame lock.

Presently described is a frame lock (10) for securing a wheel of a mode of transport to a part of its frame as exemplified in FIG. 1. The frame lock (10) comprises: a ring bolt (200) moveable between a release (open) position and closed position a chain-bolt latch (100) for latching to a chain bolt (180) of a securing cable, configured such that the chain-bolt latch (100) is able to latch to the chain bolt (180) when the ring bolt is in the release position or the closed position, and the chain-bolt latch releases the chain bolt when the ring bolt is moved from the closed position to the release position. In FIG. 1 the ring bolt (200) is in the release (open) position.

Thus, the chain-bolt latch (100) is able to latch to the chain bolt (180) when the ring bolt is in the release position, and is able to latch to the chain bolt (180) when the ring bolt is in the closed position. The ring bolt (200) is manually moveable between the release (open) position and closed position. The ring bolt (200) may be biased (e.g. by a spring) in the release position; the ring bolt (200) may return by force of a spring from the closed position to the release position. The movement of the ring bolt (200) towards the release position also releases chain bolt (180).

The mode of transport is any to which the frame-lock can be attached such that the ring bolt can in the close position lock around a part of a wheel (e.g. rim) of the mode of transport. Examples of modes of transport include bicycle, unicycle, scooter, electrically or fuel (e.g. petrol, diesel) driven transporter. Typically the mode of transport is disposed with a frame to which the frame-lock can be attached. Most bicycles have a standard fitting for receiving a frame lock.

The ring bolt (200) typically comprises a segment of a circular ring moveable around a centre of the ring between a release (open) position and closed position. The ring bolt (200) may be biased in the release (open) position by a compliant member (206) (e.g. spring). The ring bolt (200) is typically made from a strong, rigid, hard and tamper-proof material, such as a hardened alloy steel.

The ring bolt may be provided with a handle (208), for manual movement of the ring bolt (200) from the release (open) to the closed position. An exemplary handle (208) is shown in FIGs. 9A, 9B, 10 and 11. The handle (208) may be disposed in fixed relation to the ring bolt (200).

The handle (208) may be disposed hinged in relation to the ring bolt (200). The handle (208) may be attached to the ring bolt (200) via a hinge (2083). An exemplary hinged handle (208’) is shown in FIGs. 16A to 16C. The hinged handle may be moveable between a 1^st hinge position and 2^nd hinge position. In the 1^st hinge position the hinged handle (208) may be prevented from moving the ring bolt (200) from the release to the closed position. In the 2^nd hinge position the hinged handle (208’) may be able to move the ring bolt (200) from the release to the closed position. The hinge (2083) may have only one degree of freedom of rotation. An axis of rotation (2085) of the hinge may be parallel to the chassis (300). An axis of rotation (2085) of the hinge may be parallel to a planar ring bolt (200). The hinged handle (208’) may be provided with a compliant member (2084) (e.g. torsion spring) configured to bias the hinged handle in the 1^st hinge position.

The hinged handle hinders accidental movement of the ring bolt (200) from the release position towards the closed position, for instance, when the mode of transport is a bicycle provided with a rear passenger seat; there is a danger that a foot of the rear passenger pushes the handle to engage the ring bolt while the bicycle is in motion.

According to one aspect, hinged handle may be disposed with a handle protrusion (2081) that engages with a holder (313) (e.g. notch, hook) provided on or in fixed relation to the chassis (300) when the ring bolt (200) is in the release position and the hinged handle is in the 1^st hinge position. With the handle protrusion engaged in the holder (313), movement of the ring bolt (200) from the release to the closed position is prevented. When the hinged handle is moved from the 1^st hinge position to the 2^nd hinge position, the handle protrusion (2081) is cleared from the holder (313), and the hinged handle is able to move the ring bolt (200) from the release to the closed position. The holder (313) may be disposed in a lip or folded edge (311) of the chassis (300), in particular of the receiving limb (314) of the chassis. The lip (311) may contain a guiding surface that guides the handle protrusion (2081) back into the holder (313) when the ring bolt (200) returns from the closed position to the release position.

The chain bolt latch (100), as exemplified in FIGs. 2, 2A and 2B and 3A to 3G is a mechanism that latches (i.e. temporarily retains) a chain bolt (180) of a securing cable to the frame lock, in particular to a frame lock chassis (300). When the chain bolt latch (100) engages with the chain bolt (180), axial (sliding) movement of the chain bolt (180) is limited. Typically the chain bolt is disposed with a circumferential groove (182) that engages with a pawl (120) of the chain bolt latch (100) to limit axial (sliding) movement.

The chain bolt latch may comprise a lever (110). The lever may be moveable (tiltable) by rotation around an axis of rotation (112) between a deployed position (FIG. 3A) and retracted position (FIGs. 3D to 3F). The lever comprises a lever body (118) that tilts around axis of rotation (112) (i.e. a part of revolute joint), tilting the lever between the deployed and retracted position. The axis of rotation (112) of the lever may be perpendicular to a direction of insertion (184) of the chain bolt into the chain bolt latch. Rotation range of the lever may be limited e.g. by a lever rotation limiter (114).

The lever may comprise with a lever pawl (120). The lever pawl (120) may be configured to latchingly engage with the chain bolt (180) when the lever is deployed. By latchingly engage, it is meant that the lever pawl (120) allows movement of the chain bolt in an insertion direction (184) to latch onto the chain bolt and prevent movement of the chain bolt in a withdrawal direction when the lever is deployed. The lever pawl (120) may be configured to disengage from the chain bolt when the lever is retracted. The lever pawl (120) may allow movement of the chain bolt in an insertion and withdrawal direction when the lever (110) is retracted. The lever pawl may project away from the lever body (118) towards a receiving space (116) for the chain bolt.

The lever pawl (120) may be provided with a cammed surface (122). A cammed surface (122) is rounded and/or sloped. An application of force in an insertion direction by the chain bolt to the cammed surface, causes movement of the lever away from the chain bolt receiving space (116) or towards the retracted position. The lever pawl (120) may be provided with a stop edge (124). The stop edge (124) engages with the chain bolt (180), more in particular with the circumferential groove (182), to prevent withdrawal of the chain bolt when the lever is deployed.

The lever (110) may further comprise a 1 ^st pin (130) and 2^nd pin (132) each configured to receive a force. The application of the force to the 1^st pin (130) rotates the lever to the deployed position. The application of the force to the 2^nd pin (132) rotates the lever to the retracted position. The limited rotation range of the lever prevents it from exceeding the deployed position or retracted position. The 1^st pin (130) and 2^nd pin (132) may project away from the lever body and away from the chain bolt receiving space (116). The 1^st pin (130) and 2^nd pin (132) may be disposed on an underside of the lever body.

The force may be applied in a plane parallel to the axis of rotation (112) of the lever (100). The application of the force between the 1^st pin (130) and 2^nd pin (132) is controlled by movement of the ring bolt. In particular the force may be supplied by an activating bar described later below. The chain bolt latch (100) may further comprises an ejector spring (136) (e.g. helical compression spring), configured to eject the chain bolt (180) when the lever (100) is moved from the deployed to retracted position.

The chain bolt latch (100) may further comprise an activation bar (150) configured to swing or rotate between:

- a 1^st position contacting and providing the force to the 1^st pin (130) to rotate the lever to the deployed position, and

- a 2^nd position contacting and providing the force to the 2^nd pin (132) to rotate the lever to the retracted position.

The activation bar (150) may be biased in the 1^st position by a compliant member (152) (e.g. helical compression spring). The activation bar is moveable (i.e. is able to swing) by rotation around an activation bar axis of rotation (134). The activation bar axis of rotation (134) may be disposed perpendicular to the lever (100) axis of rotation (112). The activation bar axis of rotation (134) and the lever axis of rotation (112) may cross.

The ring bolt (200) may be disposed with a ring bolt pawl (210) configured to push the activation bar (150) from the 1^st position to the 2^nd position during movement of the ring bolt (200) from the closed position to the release position. A ring bolt pawl (210) is shown in FIGs. 1 and 6 to 8B; a detailed view is in FIG. 4.

The ring bolt pawl (210) may be rotatably (1DOF) attached to a fixed position on the ring bolt (200). An axis of rotation (214) of the ring bolt pawl (210) may be parallel to an axis of rotation of the ring bolt (200).

The ring bolt pawl (210) may be moveable between a deployed position and a retracted position. In the deployed position (e.g. FIGs. 7A, 7C - 6G), the ring bolt pawl (210) protrudes radially outwards from the ring bolt (200). In the retracted position the ring bolt pawl (210) (e.g. FIGs. 7B) is withdrawn i.e. pushed radially towards a centre of rotation of the ring bolt (200). The ring bolt pawl (210) may be biased (by a spring) in the deployed position.

The ring bolt pawl (210) may be provided with a cammed surface (212), wherein the activation bar (150) maintained in the 1^st position contacts the ring bolt pawl (210) along the cammed surface (212) thereby moving the ring bolt pawl (210) towards the retracted position during movement of the ring bolt (200) from the open to closed position. In other words, movement of the cammed surface (212) in relation to the activation bar (150) maintained in the 1^st position, causes corresponding movement of the ring bolt pawl (210) towards the retracted position.

The ring bolt pawl (210) may be provided with a stop edge (216), wherein the activation bar (150) in the 1st position is advanced by the ring bolt pawl stop edge (216) in the deployed position to the 2^nd position during movement of the ring bolt from the closed to open position. In other words, the ring bolt pawl stop edge (216) engages with the activation bar (150) to push the activation bar (150) to the 2^nd position. The ring bolt pawl stop edge (216) may be disposed on an edge of the ring bolt pawl (210) facing a direction of movement of the ring bolt (200) to the release (open) position.

The ring bolt pawl (210) may be provided with a rotation limiter (218), that stops rotation of the ring bolt pawl (210) relative to the ring bolt (200) beyond the deployed position.

The frame lock (10) is provided with a chassis (300) supporting the ring bolt (200) and chain bolt latch (100). The chassis (300) for a frame lock is typically rigid, and designed to withstand tampering e.g. bending or twisting. An exemplary chassis is shown in FIGs. 6, 9A and 9B.

Chassis (300) has a lower body (310) an upper body (320). The chassis (300) has a rear face (302) facing the frame of the mode of transport, and a front face (304) opposing the rear face. The lower body (310) contains a reception space (312) for receiving a part of the wheel. The chassis (300) comprises a bearing limb (313) and a receiving limb (314) flanking the reception space (312) having an open end (316) for receiving a part of the wheel. The ring bolt (200) is moveable between the release position and the closed position relative to the chassis (300). The ring bolt (200) in the closed position closes the open end (316) of the reception space (312), thereby securing the part of the wheel in the reception space.

The chassis (300) may comprise one of more attachment openings (306) (e.g. circular hole, linear or curved slot) for attachment of the frame lock (10) to the frame of the mode of transport. At least one attachment opening may be positioned in each of the bearing limb (313) and receiving limb (314). The chassis may disposed with a (kidney-shaped) slot (308) having a front side (308a) (on the front side of the chassis (304)) and an opposing rear side (308b) (on the rear side of the chassis (302)). An exemplary slot (308) is shown in FIGs. 5, 6, 8, 9A and 9B. The slot (308) may be kidney-shaped or curved. The activating bar (150) may be disposed with a tab (154) fixed in relation to the activating bar (150), wherein the activating bar (150) is positioned on the front side (308a) of the slot (308) and the tab position on the rear side (308b) of the slot (308), thereby flanking the chassis (300) and limiting movement of the activating bar (150) in a direction of the axis of rotation (134) of the activating bar. The arrangement further prevents the activating bar (150) from lifting from the chassis (300).

The lever (110) and activation bar (150) are attached to the chassis by the respective revolute joints that rotate around the respective axes of rotation (112, 134). The lever (110) and activation bar (150) are disposed on the front face (304) of the chassis (300). The axis of rotation (112) of the lever (110) may be parallel to a planar front (304) or back face (302) of the chassis. The axis of rotation (134) of the activation bar (150) may be perpendicular to a planar front (304) or back face (302) of the chassis.

The activation bar compliant member (152) may be attached at one end to the chassis (300). The ring bolt compliant member (206) may be attached at one end to the chassis (300). The chassis (300) may be provided with a rotation limiter (324), configured to limit rotation (tilting) of the lever (110). The chassis rotation limiter (324) may engage with the lever rotation limiter (114), to limit rotation or tilting of the lever (110).

The chassis (300) may be disposed with an anti-jacking cover (350). An anti-jacking cover (350) is a covering rigidly attached to the chassis (300) that covers at least a part of the ring bolt (200). In particular, the anti-jacking cover may have a circular segment shape. In may follow the shape of a part of the ring bolt. It may cover the ring bolt (200) in the region of the handle (208) between the ring bolt (200) release and open position. This region corresponds to a travel distance or path of the handle (208). A gap (352) between the chassis (300) and the anti-jacking cover (350) allows travel by the handle (208). A typical frame lock can be defeated by inserting a flat-edge screw driver or other tool in a gap between the ring bolt (200) and chassis (300) in the region of the travel path, thereby lifting the ring bolt (200) away from the chassis (300) and disengaging the locking pin (405). The anti-jacking cover (250) hinders tampering by limiting the distance by which the ring bolt (200) can be separated from the chassis (300), namely away from the front face of (304) the chassis (300). The anti-jacking cover (250) may be made from a rigid and strong material such as a hardened alloy steel. It may have a partially curved transverse cross-sectional profile corresponding to a circular transverse cross-sectional profile of the ring bolt (200). It may be attached to the chassis (300) by one or more welded connections or using one or more fixtures (354) (e.g. rivet, bolt). An exemplary antijacking cover (350) is shown in FIGs. 9A, 9B, 10, 10B.

The ring bolt (200) may be disposed with a ring bolt notch (204) configured for engaging with a moveable locking pin (405) moveable between an engaged position and a disengaged position. The moveable locking pin (405) in the engaged position secures the ring bolt (200) in the closed position. The moveable locking pin (405) in the disengaged position releases the ring bolt (200). Wherein the moveable locking pin slidably moves, e.g. has one degree of freedom of movement. The moveable locking pin (405) may be biased (e.g. by a spring) in the engaged position. In FIGs. 7D and 7E the moveable locking pin (405) is shown in the engaged and disengaged positions respectively. The spring may be disposed around of shaft of the moveable locking pin (405), on portion of the locking pin (405) towards the end that engages with ring bolt notch (204).

The moveable locking pin (405) in the engaged position engages or contacts with the ring bolt notch (204), preventing movement (rotation) of the ring bolt (200). The moveable locking pin (405) in the disengaged position is drawn clear of the ring bolt notch, allowing movement (rotation) of the ring bolt (200).

Wherein the moveable locking pin (405) is supported by and moves relative to the chassis (300). The moveable locking pin may be moveable responsive to an electronic signal. The moveable locking pin may be actuated by an electrical movement generator e.g. servo motor, motor, linear actuator.

An exemplary movement of the chain bolt latch (100) is shown in a sequence of FIGs. 3A to 3G. In FIG. 3A chain bolt (180) is advanced into chain bolt receiving space (116). Force applied to the cammed surface of the lever pawl (120) causes downward rotation of the lever (110) around axis of rotation (112) (FIG. 3B). Chain bolt groove (182) engages with the lever pawl (120) (FIG. 3C); lever (110) is returned to deployed position by the activation bar (150) - biased in the 1 ^st position - applying force to the 1 ^st pin (130); therewith the lever (110) latches onto the chain bolt (180) thereby preventing withdrawal; spring (136) is compressed. Movement of the activation bar (150) to the 2^nd position (FIG. 3D) - caused by a return of the ring bolt (200) to the release position - applies force to the 2^nd pin (132); lever (110) is moved to the retracted position. The spring (136) applies force to the chain bolt (180) causing it to be ejected from the receiving space (116) (FIGs. 3E, 3F). Return movement of the activation bar (150) to the 1^st position (FIG. 3G) applies force to the 1^st pin (130); lever (110) is returned to the deployed position.

An exemplary movement of the ring bolt (200), ring bolt pawl (210), and interaction with the chain bolt latching mechanism (100) is shown in a sequence of FIGs. 7Ato 7I. In FIG. 7A chain bolt (180) is latched (held by) by the latching mechanism (100) (equivalent to FIG. 3C) while the ring bolt (200) is in a release position. Ring bolt pawl (210) is in a deployed position and the activation bar (150) in the 1^st position is disposed so as to potentially engage with the cammed surface (212). Rotation of the ring bolt (200) towards a closed position (FIG. 7B) rotates the ring bolt pawl (210) past the activation bar (150); the ring bolt pawl (210) is moved to the retracted position by application of force of activation bar (150) in the 1^st position to the cammed surface (212); the activation bar (150) remains in the 1^st position. In FIG. 7C, the ring bolt (200) is rotated further towards the closed position; the ring bolt pawl (210) is clear of the activation bar (150). In FIG. 7D, the ring bolt (200) has rotated fully to the closed position; the moveable locking pin (405) is engaged in the ring bolt notch (204). In FIG. 7E, the moveable locking pin (405) has been moved to the disengaged position. Spring (206) forces a return of the ring bolt (200) towards the release position. Ring bolt pawl (210) in the deployed position moves towards the activation bar (150) (FIG. 7F) with the stop edge (216) having the potential to rotate the activation bar (150) towards the 2^nd position. In FIG. 7G, the ring bolt pawl (210) stop edge (216) pushes the activation bar (150) to the 2^nd position; at the same time, the activation bar (150) applies force to the 2^nd pin (132) moving the lever (110) to the retracted position - see FIG. 7G’. The chain bolt (180) is ejected (equivalent to FIGs. 3D to 3F). In FIG. 7H, ring bolt pawl (210) in the deployed position moves past the activation bar (150). In FIG. 7I, the activation bar (150) under force of spring (152) returns to the 1^st position applying force to the 1^st pin (130); the lever (110) returns to the deployed position (equivalent to FIG. 3G).

The frame lock (10) may further comprise a housing enclosure (500) configured to enclose electronic circuitry and one or more electromechanical elements. The housing enclosure may comprise a main body (502) forming a void space for housing the electronic circuitry and one or more electromechanical elements and a lid enclosing the void space. The housing enclosure (500), in particular the main body may be attached to the chassis (300). The housing enclosure (500), in particular the main body may be attached to the chassis by at least one (preferably one) fixture such as a screw or bolt. The housing enclosure (500), in particular the main body may be attached to an upper body (320) of the chassis (300). The housing enclosure (500), in particular the main body may be attached to a front face (304) of the chassis (300). The housing enclosure (500) is configured to protect the electronic circuitry and one or more electromechanical elements from ingress e.g. exposure to outdoor elements, especially rain and moisture. Further, the housing enclosure (500) may be configured to protect the frame lock (10) from immersion in water; immersion is used as a theft strategy to defeat the electronics or shield the frame lock from receiving GNSS and/or GPRS signals, or transmitting GPRS signals. The housing enclosure (500) is preferably made at least partially, preferably substantially from a polymeric material (e.g. polyethylene, polypropylene, polycarbonate, acrylonitrile Butadiene Styrene).

The electronic circuitry may include one or more of global positioning satellite (GNSS) module (420), Bluetooth module (470), radio-frequency identity (RFID) tag reader module (460), motion sensor module (440), capacitive sensor (455), cellular (GSM, GPRS) communication module (410), sound transducer (480), rechargable battery, controller (400).

The electromechanical elements may include one or more of mechanical contact switch, electrical movement generator, moveable locking pin (405).

The housing enclosure (500) may be formed substantially by an injection molding process. In particular, the housing enclosure (500) may be formed by an overmolding process. In overmolding, certain components (e.g. tubular boss (514), row of electrical pins (524), viewing windows (532)) of the housing are placed in a mold for the housing enclosure, and polymer forming the remainder of the housing enclosure is injected; the result is a housing enclosure in which separate components are bonded and integrated into the housing body. According to one aspect, overmolding may be used to form the main body (502) of the housing enclosure (500).

The overmolding may be used to insert one or more seals in the housing enclosure (500). In particular the main body (502) of the housing enclosure (500) may be disposed with an overmolding that is a seal (530) around an edge of the main body (502) that co-operates with an edge of the lid (504). A further overmolding may be a seal (524) lining the cylindrical lumen (522). In FIG. 15A, the main body (502) of the housing enclosure is formed by two overmolding steps. In a first step a row of electrical pins (524), tubular boss (514), and viewing window (532) are placed in a first mold and polymer forming the remainder of the housing enclosure is injected to form an intermediate (not shown). The row of electrical pins (524), tubular boss (514), isolated from the main body (502) and depicted in their eventual position and orientation in FIG. 15B. Then the intermediate is placed in a second mold and seals (530, 524) are injected; these seals isolated from the main body (502) are shown in FIG. 15C. The result of both the first and second mold is the main body (502) depicted in FIG. 15A.

The housing enclosure (500), in particular the main body may be disposed with a recess extending into the void space for slidably engaging with an anti-twist projection extending from the chassis. The anti-twist projection (332) extends from a front face (304) of the chassis (300). It preferable extends in a direction perpendicular to a planar portion of the chassis (300) to which the anti-twist projection extends. The anti-twist projection may be formed by bending an edge of the chassis e.g. at an angle of 90 deg. The anti-twist projection may have an essentially rectangular profile. It may have a longitudinal axis parallel to a front face of (304) the chassis (300). The anti-twist projection engaged in the recess prevents twisting of the housing enclosure relative to the chassis. Anti-twist projection (332) on the chassis (300) is shown in FIGs. 8, 9A, 9B, 10, 10A (detail), 11 , 14A, 14B. The recess (512) in the housing enclosure (500) main body (502) is shown in FIGs. 11, 12, 13.

The housing enclosure (500), in particular the main body (502) may be disposed with an outwardly-extending tubular boss (514) into which the moveable locking pin (405) is slidably disposed. The chassis (300) may be provided with an anti-lift projection (334) extending from the chassis (300). The anti-lift projection (334) may extend from a front face (304) of the chassis (300). It preferable extends in a direction perpendicular to a planar portion of the chassis (300) to which the anti-lift projection extends. The anti- lift projection may be formed by bending an edge of the chassis (300) e.g. at an angle of 90 deg. The anti-lift projection (334) comprises an opening (335) configured for slidably receiving the tubular boss (514), typically in an axial direction of the tubular boss. The opening (335) in the anti-lift projection (334) may have a form of a circle. The opening (335) formed in the anti-lift projection (334) may have a form of a diametrically truncated circle, wherein the truncated edges of the circle are open. Once the tubular boss (514) is engaged in the anti-lift projection opening (335), the chassis (300) cannot be separated from the housing enclosure (500, 502) by a moving the housing enclosure (500) in a direction perpendicular to the front face (304) of the chassis (300). A central axis of the tubular boss (514) may be perpendicular to a longitudinal axis of the anti-twist projection (332). The arrangement allows the insertion of the anti-twist projection (332) into the recess (512) by rotation of the housing enclosure (500) around the tubular boss (334) when the tubular boss (334) is engaged in the anti-lift projection (334). Anti-lift projection (334) on the chassis (300) is shown in FIGs. 10, 10A, 11, 14A and 14B. Rotation of the chassis (300) relative to the housing enclosure (500) main body (502) when the tubular boss (514) is engaged in the anti-lift projection (334) is shown in FIGs. 14A and 14B.

The outwardly-extending tubular boss (514) is preferably lined with or formed from a low- friction materal such as polytetrafluoretheen (PTFE). The low-friction material facilitates radial compression of a sealing ring (e.g. O-ring) around the locking pin (405) to prevent or reduce ingress. Radial compression of a sealing ring can be problematic because high forces are needed to overcome friction exerted between a compressed sealing ring and the housing; either the sealing ring merely contacts the housing giving rise to a seal prone to ingress, or a more powerful electrical movement generator is needed. By providing the low-friction materal, the sealing ring can be compressed to hinder ingress and a less powerful movement generator can be used. Where outwardly-extending tubular boss is made from the low-friction materal, the housing enclosure may be formed by an overmolding process in which at least the outwardly-extending tubular boss made from the low-friction materal is placed in a mold for the housing enclosure, and polymer forming the remainder of the housing enclosure is injected; the result is a housing enclosure in which separate components are bonded and integrated into the housing body.

The frame lock (10) may further comprise a mobile or cellular (GSM, GPRS) communication module (410). The mobile communications module is configured to receive instructions for controlling movement of the moveable locking pin (405). The mobile communication module (410) may be operatively connected to a controller (400). The mobile communications module (410) allows for wireless control of the electrical movement generator. The mobile communications module may be operatively connected to a controller (400). The frame lock (10) may further comprise a Bluetooth module (470). The Bluetooth module is configured to receive a Bluetooth signal for controlling movement of (i.e. disengaging) the moveable locking pin (405). The Bluetooth module (470) may be operatively connected to a controller (400). The frame lock (10) may be opening using a smartphone paired with the Bluetooth module (470). The Bluetooth module (470) allows for wireless control of the electrical movement generator. The Bluetooth module (470) may be operatively connected to a controller (400). The frame lock (10) may further comprise a radio-frequency identity (RFID) tag reader module (460). The RFID tag reader module is configured to identify an RFID tag for controlling movement of (i.e. disengaging) the moveable locking pin (405) The RFID tag reader module (460) may be operatively connected to a controller (400). The frame lock (10) may be opening using a RFID key e.g. integrated into a card. The RFID tag reader module (460) allows for wireless control of the electrical movement generator. The RFID tag reader module (460) may be operatively connected to a controller (400).

The frame lock (10) may further comprising a Global Navigation Satellite System (GNSS) module (420) configured to receive satellite signals (GPS, GLONASS, Galileo or BeiDou) for determining a global position of the frame lock. The GNSS module (420) may be operatively connected to the cellular communications module, for transmission of the global position of the frame lock across a mobile communications network. The cellular communication module (410) may be operatively connected to a controller (400). The GNSS module (420) may be activated by the motion sensor module (440) and the position of the frame lock (10) may be reported using the mobile (cellular) communications module (420). The GNSS module (420) may be operatively connected to a controller (400).

The frame lock (10) may further comprise a motion sensor module (440) configured to detect motion of the frame lock, in particular when the ring bolt (200) is in the closed position. The motion sensor module (440) may comprise one or more of a linear accelerometer, an angular accelerometer, a gyroscopic sensor. The linear or angular accelerometer may be 1-, 2-, 3- or more axis accelerometer. The motion sensor module may be operatively connected to the mobile (cellular) communications module, for transmission of a motion alert across a mobile communications network. The motion sensor module (440) may be operatively connected to a controller (400). The frame lock (10) may further comprise a sound transducer (480) configured to emit a sound, in particular, an alarm sound (e.g. loud, high-pitched, constant or intermittent noise). The sound transducer (480) may be operatively connected to the motion sensor module (440), to emit an alarm sound when the frame lock (10) (i.e. mode of transport) is moved while the ring bolt (200) is in the closed position. The sound transducer (480) may be operatively connected to a controller (400). The sound transducer may be a loud speaker, buzzer, alarm speaker. The sound transducer (480) may be operatively connected to a controller (400).

The sound transducer may be disposed in the housing enclosure (500) such that an output side of the sound transducer (e.g. cone side) is exposed to the environment for direct emission of sound. The output side may be in connection with one or more openings in the housing enclosure. According to one aspect, the housing enclosure (500), preferably the main body (502), is disposed with an outwardly extending holder (FIG. 12, 526) having a cylindrical lumen (522), and the sound transducer is supported within the lumen (522). A seal (FIG. 15A, 530) between an inner wall of the lumen (522) and the sound transducer reduces or prevents ingress, e.g. moisture, particles, and/or liquid entering the housing enclosure (500).

The frame lock (10) may further comprise at least one mechanical contact switch (450). The mechanical contact switch (450) activated by movement of an element such as the moveable locking pin (405), lever (110), or chain bolt (180). The mechanical contact switch (450) may indicate a status of the locking pin (405) e.g. in the engaged position or the disengaged position. The mechanical contact switch (450) may indicate a status of the lever (110) e.g. in the deployed or retracted position. The mechanical contact switch (450) may indicate a status of the chain bolt (180) e.g. in a latched position or unlatched position. The mechanical contact switch (450) may be operatively connected to a controller (400).

The mechanical contact switch may be a momentary contact switch, normally open or normally closed. The mechanical contact switch may be a microswitch. The mechanical contact switch may be disposed within the housing enclosure, and is positioned for visibility when the housing enclosure is opened. In particular, the mechanical contact may be positioned for visibility when the lid is removed from the housing enclosure. The momentary contact switch positioned for visibility (e.g. mounted on a top-side of a PCB) allows an assembly technician to see that the locking pin (405), or an attachment (e.g. projection) thereto is on the correct side of the momentary contact switch, and accordingly operates it correctly.

The frame lock (10) may comprise a mechanical contact switch (450) activated by movement of the moveable locking pin (405) and positioned for visibility when the housing enclosure is opened. The moveable locking pin (405) in the engaged or disengaged position may apply force to the mechanical contact switch. According to one aspect, the locking pin (405), or an attachment (e.g. projection) thereto, depresses the mechanical contact switch (450) in the engaged position. A binary signal is generated that may be communicated (via the mobile communications module (410)) to a remote server indicating that the ring bolt (200) of the mode of transport is locked. Accordingly, if the mode of transport is stolen, an insurer has access to the data indicating whether the whether the ring bolt (200) was closed or open at the time of theft.

The frame lock (10) may further comprise at least one capacitive sensor (455). The capacitive sensor (455) may be activated by movement of an element such as the chain bolt (180), moveable locking pin (405), lever (110). The capacitive sensor (455) may indicate a status of the chain bolt (180) e.g. in a latched position or unlatched position, locking pin (405) e.g. in the engaged position or the disengaged position, or lever (110) e.g. in the deployed or retracted position. The capacitive sensor (455) may be operatively connected to a controller (400).

According to one aspect, the chain bolt (180) in the latched position activates the capacitive sensor (455). A signal is generated that may be communicated (via the mobile communications module (410)) to a remote server indicating that the chain bolt (180) has been applied. Accordingly, if the mode of transport is stolen, an insurer has access to the data indicating whether the whether the chain bolt (180) was latched in place or not at the time of theft. Advantageously, the capacitive coupling effect of the chain bolt (180) can pass through a surface; accordingly, the capacitive sensor (455) may be mounted inside the housing enclosure, thereby protecting it from ingress e.g. moisture, particles and/or water immersion. The frame lock (10) may further comprise a controller (400), typically containing a computer processor, or circuitry for executing computer instructions.

The controller (400) may be operatively connected to one or more of the mobile communications module (410), movement generator (430), Bluetooth module (470), sound transducer (480), GNSS module (420), motion sensor module (440), mechanical contact switch(es) (450), capacitive sensor(s) (455), RFID tag reader module (460); the processor may facilitate one or more of the actions described herein in relation one or more of the preciously-mentioned to the modules or parts.

The controller (400) may be configured to receive and process signal received from one or more of the mobile communications module (410), GNSS module (420), motion sensor module (440), mechanical contact switch(es) (450), capacitive sensor(s) (455), RFID tag reader module (460), Bluetooth module (470).

The controller (400) may be configured to process and send control signals to one or more of the mobile communications module (410), movement generator (430), Bluetooth module (470), sound transducer (480). An exemplary arrangement of modules is shown in

FIG. 17.

The controller (400) may be provided as a separate device, or integrated partially or fully in one or more of one or more of the mobile communications module (410), GNSS module (420), motion sensor module (440), mechanical contact switch(es) (450), capacitive sensor(s) (455), RFID tag reader module (460), Bluetooth module (470), movement generator (430). The components may be attached to a printed circuit board.

The frame lock (10) may further comprise a protective cover. The protective cover covers the housing enclosure, the ring bolt (200) in the release position, and the chassis (300).

The chain-bolt (180) does not require a mechanical key or a separate electro-mechanical system to release the chain-bolt (180). This reduces the complexity of the lock, and the need for separate actuators, and hence consumption of power to release the chain bolt. The chain bolt latches to the chain-bolt latch (110) whether the ring bolt (200) is in the release position (open) or the closed position. Thus, the chain-bolt latch (100) is able to latch to the chain bolt (180) when the ring bolt is in the release position, and is able to latch to the chain bolt (180) when the ring bolt is in the closed position. The movement of the ring bolt (200) from the closed position to the open position causes chain-bolt latch (100) to release the chain bolt (180), thereby avoiding a separate chain-bolt release mechanism. The application of manual force to move the ring bolt (200) from the release position to closed position also reduces complexity and power consumption.
