Definitions

  • the invention relates to a lock. Although already numerous different locks are commercially available, there is an undiminished need to develop new locks resistant to forcing. The invention therefore aims to provide such a lock.
  • a lock comprising a first lock member with a projecting lock pin, and a second lock member with a locking groove for receiving the lock pin, which locking groove, being rotatable between a position in which the lock pin is retained and a position in which it is released, is connected to a lock cylinder which is locked up in the second lock member and which is operable with a key, said lock pin having a thickened head connected to a constricted neck, while the locking groove consists of a cavity formed in a closing sleeve for receiving the head, which cavity communicates with the environment through an opening for letting through the head and a narrowed duct for receiving the neck of the lock pin, connected thereto in the direction of rotation of the closing sleeve.
  • the thickened head of the lock pin can be moved in and out of the cavity of the closing sleeve, respectively through said opening.
  • the head When the head has been moved into the cavity, it can subsequently be locked behind the narrowed duct by rotation of the closing sleeve to the retaining position, the neck of the lock pin then being positioned in this narrowed duct.
  • the lock pin In this position, the lock pin cannot be removed from the closing sleeve.
  • the lock cylinder connected to the closing sleeve affords the rotation thereof. In this way, the lock pin is retained in the second lock member in such an effective and solid way, that it becomes extremely difficult to force the lock pin out of the second lock member.
  • a transverse duct connected to the duct containing the closing sleeve will be formed in the second lock member, in such a way that it communicates with the opening formed in the closing sleeve in the releasing position of the closing sleeve, and with the narrowed duct in the retaining position of the closing sleeve.
  • This transverse duct will preferably have a diameter which is just large enough to let the thickened head of the lock pin pass, so that a close fit is obtained and the lock members can hardly be moved in relation to each other in their joined position, which renders it extremely difficult for unauthorized persons to break the connection between the lock members.
  • the closing sleeve is closely fitted into a duct formed in the second lock member.
  • This offers a number of additional advantages.
  • the most important advantage of the fact that the closing sleeve is closely fitted into the duct formed in the second lock member is that this prevents deformation of the closing sleeve when a great force is exerted thereon. Such a great force may, for example, be exerted when someone tries to pull the lock pin out of the locking groove.
  • lock pin and the closing sleeve cooperating therewith can be closed off completely from the environment in the joined position of the lock members, by allowing the lock members to abut, so that, on the one hand, it is virtually impossible to destroy these elements, and, on the other hand, these elements are protected from weather influences.
  • lock members comprise rims overlapping their common interface in their joined position.
  • these overlapping rims prevent that a breaking tool or the like is forced between the lock members in order to move these apart by exerting a great force and to break the connection between them.
  • the lock cylinder and the closing sleeve are inserted into the duct formed as a blind hole, while a passage of a smaller diameter for introducing a key into the lock cylinder is formed in a wall of the second lock member, in line with the blind end of the hole, and the open end of the hole is closed with a plug.
  • the lock cylinder is screwed into the second lock member, the screwing direction for unscrewing the lock cylinder from the second lock member being opposite to the direction of rotation of the locking groove from the position in which the lock pin is retained to the position in which it is released.
  • the lock according to the invention can be applied in various ways.
  • the lock members comprise recesses in which the end links of chains can be placed and fastened, as well as lock pins extending through the recesses and retaining the end links. Once placed, .the end links which are retained in the recesses by means of the locking pins can hardly be removed from the lock members in an unauthorized way.
  • lock members it is of course also. possible to fit the lock members to other elements, such as the ends of cables, bars, or other elements which can be connected to each other by means of a lock.
  • a very special embodiment of the lock according to the invention is the embodiment in which the lock is formed as a disc brake lock for a vehicle fitted with a disc brake, in particular a motorcycle, in which the first lock member is formed as a disc-shaped boss at the end of the lock pin which is opposite to the head, and the second lock member is formed as a lock housing.
  • This lock allows to immobilize a vehicle fitted with a disc brake by locking the lock on the disc of the disc brake. In most' cases, this can be done by putting the lock pin through an existing hole in the disc of the disc brake and by locking the second lock member onto the lock pin, as a result of which the lock pin is closed off at both ends by the first and the second lock member, respectively. Because of the fact that the first and the second lock member are only connected via the lock pin and not externally of the disc as well, the hole through which the lock is put can be located anywhere on the disc, independent of the distance between the hole concerned and the rim of the disc.
  • the length of the lock pin between the disc- shaped boss and the second lock member only slightly exceeds the thickness of a disc, while the second lock member has a conically shaped surface on the side of the opening to the locking groove, of which the cone angle is preferably 5-20°.
  • Fig. 1 shows a side view of a first embodiment of the lock members constituting the lock according to the invention
  • Fig. 2 is a section of one of the lock members according to the line II-II in Fig. 1, with at some distance of the lock member the elements to be received therein;
  • Fig. 3 is a longitudinal section according to a face parallel to the face of the drawing of the other lock housing of Fig. 1, with the elements received therein;
  • Fig. 4 is a first view of a closing sleeve, and
  • Fig. 5 is a view of the closing sleeve according to V in Fig. 4.
  • Fig. 6 is a perspective view of a motorcycle with a second embodiment of the lock according to the invention in the form of a disc brake lock.
  • Fig. 7 is an enlarged longitudinal section of the lock of Fig. 6, in which the lock members are shown separate from a disc brake, on both sides thereof.
  • Fig. 8 is a small-scale front view of the disc brake with the lock locked thereto.
  • the lock according to the invention consists of a first lock member 1 with a projecting lock pin 2 and a second lock member 3 with a locking groove for receiving the lock pin 2, which will be discussed in more detail hereinafter.
  • the first lock member 1 mainly consists of a massive square block made of hardened steel, in one side of which a recess 4 is formed for receiving the lock pin 2.
  • the lock pin 2 and the recess 4 have cooperating grooves 5,6 for receiving a securing ring 7. Once the lock pin 2 is secured in the recess 4 by means of the securing ring 7, it can no longer be removed from the recess 4 of the lock member 1. If, however, the recess 4, the lock pin and the .securing ring 7 are cylindrically shaped, the lock pin 2 can still rotate within the recess 4.
  • the lock member 1 On its opposite side, the lock member 1 has a recess 8 for receiving the end link 9 of a chain or the like (represented by a dotted line in fig. 2) , which, once placed in the recess 4, can be secured therein by means of a securing pin 10 which can pass through the recess 8 and the end link 9 placed therein via a transverse duct 11.
  • This securing pin 10 can be locked irremovably in the lock member 1 by means of a securing ring 12.
  • the lock member 1 may of course also be attached to other elements than a chain comprising links.
  • elements for example, cables, bars or other constructive parts are conceivable.
  • the second lock member 3 comprises a main duct 13 with a shoulder 14 formed therein.
  • the part of the main duct 13 which is situated below the shoulder 14, contains a closing sleeve 16, preferably made of a strong and ductile type of aluminium, which, as Fig. 4 shows most clearly, comprises a connecting groove 17 in the upper side thereof.
  • An operating pin 18 of the lock cylinder 15 engages into this connecting groove 17.
  • the closing sleeve 16 is retained in the respective part of the main duct 13 by a retaining plate 19, which is locked irremovably by means of a securing ring 20 in the same way as described hereinbefore. This means that, once placed, the closing sleeve 16 cannot be removed from the main duct 13.
  • the closing sleeve 16 is accessible from the front side of the second lock member 3 via a transverse duct 21.
  • This transverse duct 21 has a diameter which substantially corresponds to the diameter of the lock pin 2.
  • the lock pin 2 has a constricted neck 22 and a thickened head 23 connected thereto.
  • the thus formed lock pin 2 has to cooperate through its head 23 and neck 22 with a locking groove formed in the closing sleeve 16.
  • this locking groove mainly consists of a cavity 24 formed in the closing sleeve 16 for receiving the thickened head 23.
  • the cavity communicates with the environment via an opening 25 situated at a certain circumferential position of the closing sleeve 16. This opening 25 is just large enough to place the head 23 of the lock pin 2 in the cavity 24 or to remove it therefrom.
  • a narrowed duct 26 is connected to the opening 25 in the direction of rotation of the closing sleeve 16, the diameter of which is large enough to let the constricted neck 22 of the lock pin 2 pass .
  • Fig. 3 further shows that the lock member 3 has a recess 27 on its back side, in which a securing pin 28 is placed.
  • the design and the operation of this recess 27 and securing pin 28 correspond to those of the recess 8 and the securing pin 10 in the first lock member 1.
  • the lock members 1 and 3 can be attached to each other in order to close the lock.
  • the closing sleeve 16 is rotated by means of the lock cylinder 15 to a position, in which the opening 25 communicates with the transverse duct 21.
  • the head 23 of the lock pin 2 is placed in the internal cavity 24 of the closing sleeve 16 via the transverse duct 21 and the opening 25.
  • the screwing direction for unscrewing the lock cylinder 15 from the main duct 13 is opposite to the direction of rotation of the closing sleeve 16 from the position in which the lock pin is retained (in which the narrowed duct 26 communicates with the transverse duct 21) to the position in which the lock pin 2 is released (in which the opening 25 communicates with the transverse duct 21) . Therefore, when attempts are made to unscrew the lock cylinder 15 in an unauthorized way from the lock member 3, the closing sleeve 16 will be held in the locking position. The unauthorized opening of the lock is thus prevented.
  • the lock pin is rotationally symmetrical on its longitudinal axis, so that, ' in the locked position, both lock members 1 and 3 can rotate on this axis in relation to each other. This allows a great freedom of movement when the lock is applied to the ends of chains. This also prevents one possibility of forcing the lock.
