Definitions

  • This invention relates to anti-theft devices for bicycles.
  • the invention relates to an anti-theft device which is built into the bicycle and which enables the bicycle to be immobilised so that it cannot be ridden.
  • a device comprising a pin mounted on or within the frame of a bicycle near the bottom bracket and movable to a position in which it engages the bottom bracket axle (to which the pedal cranks and chain wheel are fixed), to prevent rotation of the axle.
  • a device is relatively complex and requires structural alteration to the frame of the bicycle.
  • a crank for a bicycle in which a component forming part of or attached to the crank is movable to a locking position in which, in us “ e, the component projects sideways from the crank so as to engage the frame or a wheel of the bicycle when the crank is turned, and locking means are provided to lock the component in the locking position.
  • the said component is a pedal attached to the crank, the pedal being movable from an operative position in which it extends laterally outwards from the crank to the locking position in which it extends laterally inwards.
  • the pedal is mounted on the crank so that it can be turned between the operative and locking positions about an axis in the plane perpendicular to the axis of rotation of the crank and the pedal.
  • the crank includes a mounting member on which the pedal is mounted and the mounting member is pivoted to the body of the crank to enable the pedal to be turned between the operative and locking positions.
  • the locking means comprises a key-operated lock mounted in the crank and having a bolt member movable into engagement with the mounting member in each of the operative and locking positions.
  • the crank is divided into two parts at a location between the radially inner and outer ends of the crank, the two parts of the crank being connected together so that the radially outer part can rotate relative to the radially inner part about the longitudinal axis of the crank, to enable the pedal to be turned between the operative and locking positions.
  • a pedal is mounted on the end of the crank, and the movable component is an elongate member movable between a retracted position, in which it lies against or within the pedal so as not to interfere with normal operation of the pedal, and a locking position, in which it projects sideways from the pedal.
  • the elongate member is a bolt arranged with its longitudinal axis parallel to the axis of rotation of the crank and slidable in the direction of its longitudinal axis.
  • the elongate member is a bar pivotally mounted on the pedal for movement between the retracted and locking positions.
  • the invention also includes a bicycle fitted with a crank as defined above.
  • Figure 1 is a perspective view of a bicycle to which the anti-theft device of the invention may be fitted
  • Figure 2 is a front elevation of a crank for a bicycle in accordance with one embodiment of the invention

  • Figure 10 is an end elevation of the pedal of Figure 9
  • Figure 11 is a diagrammatic front view of a bicycle fitted with pedals as shown in Figures 8 to 10, with the bolts in the locking position,
  • Figure 12 is a front elevation of a crank and pedal in accordance with a fourth embodiment of the invention, showing a locking bar in the locking position
  • Figure 13 shows the pedal of - Figure 12, with the bar in the retracted position
  • Figure 14 is an end elevation of the pedal of Figure 13
  • a crank 10 for a bicycle 2 has at one end an enlarged portion 12 for connection to the bottom bracket axle of the bicycle.
  • the crank 10 has an insert 14 formed with a bore 16 to which a pedal 18 of conventional construction can be fixed in the usual manner.
  • the insert 14 fits into a recess 20 in the crank 10 and is pivotally mounted on a pivot pin 22 fixed to the crank 10 and extending through a bore 24 in the insert 14, so that the insert 14 can pivot about an axis 26 which is perpendicular to the axis of the bore 16.
  • Two grooves 28 and 30 are formed in opposite ends of the insert 14.
  • a locking mechanism 32 for locking the insert in one of two positions comprises a cylinder lock 34 mounted on the crank 10.
  • the body 36 of the cylinder lock 34 is housed within a recess 38 in the crank 10 and has a bolt member 40 slidable in the recess.
  • the bolt member 40 is movable in between a projected position in which it engages in one or other of the grooves 28 and 30 in the insert 14, to lock the insert in position, and a retracted position in which the insert is free to turn on the pivot pin 22.
  • the lock can be operated, to move the bolt member 40, by means of a key inserted from the outside of the crank.
  • the pedal 18 fixed to the insert In the operative position of the insert 14, the pedal 18 fixed to the insert is in the normal position. In the locking position, as shown in Figure 5, the pedal projects to a point beyond the side of the frame 4 of the bicycle opposite the crank 10 to which the pedal 18 is attached, so that if someone attempts to ride the bicycle with the pedal in this position, the pedal will engage the frame 4 or the wheel 6 of the bicycle, to prevent the crank being turned.
  • the pedal 18 is movable between its normal operating position and a locking position in which it extends in the opposite direction.
  • the crank 42 is of conventional construction except that it is made in two parts 44 and 46, connected together to allow the radially outer part 44, to which the pedal 18 is connected, to rotate, relative to the radially inner part 46, about the longitudinal axis of the crank, as indicated by the arrows in Figure 6.
  • the outer crank part 44 may be formed with a projecting tapered spigot 48 fitting into a complementarily shaped recess 50 in the inner part 46 of the crank, the spigot and recess being shaped so that the outer part 44 can take up two positions separated by 180° relative to the inner part 46 of the crank.
  • a lock 52 is provided, to enable the outer part 44 of the crank 42 to be locked in either of its positions, using a key 54.
  • FIGs 8 to 11 show a third embodiment of the invention, comprising a pedal 60 mounted on a conventional crank 62.
  • a bolt 64 is slidable in the pedal between a retracted position, shown in Figure 9, in which it is contained within the pedal and does not interfere with its normal operation, and a projected position, shown in Figure 8, in which the bolt 66 projects inwards from the pedal.
  • a key-operated cylinder lock 68 movable with the bolt 64 is provided to lock the bolt 64 in each of the two positions, by means of a latch member which engages the pedal 60 in each position.
  • the length of the bolt 64 is such that, in its projected position, it can engage the wheel 6 or the frame 4 of the bicycle, to prevent the crank turning. Moving the bolt into engagement with the wheel of the bicycle has the advantage that it prevents the bicycle from being wheeled away, as well as preventing it from being ridden.
  • a locking device in accordance with this embodiment of this invention can be fitted to one or both pedals of the bicycle.
  • a fourth embodiment of the invention shown in Figures 12 to 14, similarly comprises a pedal 80 mounted on a conventional crank 82.
  • a bar 84 is mounted on the pedal on a pivot 86 so as to be rotatable about an axis 88 perpendicular to the plane of the pedal and positioned near the corner of the pedal nearest to the crank 82.
  • the bar 84 is movable through 180° between a retracted position, shown in Figure 13, in which it lies against the side of the pedal and does not interfere with its normal operation, and a projected position, shown in Figure 12, in which the bar 84 projects inwards from the pedal.
  • a cylinder lock 90 incorporated in the pivot 86 can be operated by a key to lock the bar 84 in each of the two positions.
  • the length of the bar 84 is such that, in its projected position, it can engage the wheel 6 or the frame 4 of the bicycle, to prevent the crank turning.

Abstract

Dispositif antivol incorporé à une bicyclette, dans lequel une pièce faisant corps avec la manivelle de la pédale de la bicyclette, ou étant fixée à celle-ci, peut se mettre en position de verrouillage de sorte qu'elle se trouve en saillie dans le sens latéral par rapport à la manivelle, et qu'elle entre en prise avec le cadre ou l'une des roues de la bicyclette lorsque l'on fait tourner la manivelle, l'utilisation de la bicyclette étant ainsi rendue impossible. On a prévu une serrure destinée à bloquer la pièce en position de verrouillage. Selon un mode de réalisation, l'une des pédales (18) de la bicyclette constitue la pièce de verrouillage, cette pédale (18) étant apte à tourner sur 180° de la position normale à la position de verrouillage dans laquelle elle s'étend vers l'intérieur et entre en prise avec le cadre (4) de la bicyclette. Selon un autre mode de réalisation, la pièce est un élément allongé (64, 84) monté coulissant ou rotatif sur la pédale (60, 80) entre sa position normale et la position de verrouillage dans laquelle il fait saillie vers l'intérieur et entre en prise avec le cadre (4) ou la roue (6) de la bicyclette.
