  • the present invention relates to a locking device for a sliding shutter or rolling shutter, comprising a lock housing, a cylindrical locking bolt, and guiding means arranged in the lock housing, in which the locking bolt is axially slidable between a protruding position and a retracted position in relation to the lock housing.
  • the locking bolt is provided with at least a first and a second recess, and a cylindrical locking pin is arranged axially rotatable in the lock housing, the locking pin being arranged to engage the second recess through axial rotation, to provide an axial locking of the locking bolt in said retracted position.
  • the burglary protective devices must be burglar-proof and at the same time easy to handle and non-bulky.
  • Regarding the closing and closure of shop spaces in shopping malls, garage doors, and other openings, e.g., sliding shutters or rolling shutters are a suitable solution. These close large spaces, are easy to handle, and are non-bulky in the open position, and are often driven by an electrical motor unit. However, there are requirements that these must be securely locked in the shut position by a mechanical locking to prevent burglary during which the sliding shutter or rolling shutter through damage is broken open. Therefore, there is a need for a secure and effective mechanical locking device which securely locks sliding shutters or rolling shutters, and which in addition is easy to handle.
  • US 5 806 352 A discloses a locking bracket which includes a mild steel plate having two opposed longitudinally extending edges and two opposed transversely extending edges.
  • a locking formation in the form of an upstanding protrusion is welded to the plate for selectively captively retaining a locking device such as a padlock.
  • En aperture in the plate is longitudinally spaced apart from the protrusion for receiving a bolt which extends from the padlock.
  • the bolt passes through the aperture and like apertures formed in a first and second article which are intended to be locked.
  • the first article can be a sliding shutter and the second article can be the channel along which the sliding shutter slides.
  • GB 2 298 447 A discloses a locking mechanism comprising a padlock device engageable with a displaceable cylindrical anchor member, said anchor member having two positions, an extended position in which the padlock device can engage with the anchor member by engagement of the padlock device with a circumferential recess in the external end of the anchor member, and a retracted position inside a tubular member in which the padlock device cannot engage with the anchor member.
  • the tubular member can be set in a floor, e.g., and the anchor member can be passed through a hole in the lower edge of a sliding shutter before the padlock device engages with the anchor member.
  • the anchor member is biased by a spring and can take its retracted position by pushing the anchor member into the tubular member and rotating it by means of a protrusion disposed at the external end of the anchor member so that a stop engages a groove in the anchor member.
  • US 4 229 955 A describes a lock for roller shutters, comprising a body, a cylindrical locking bolt, and a bore in which the locking bolt is axially slidable between a protruding position and a retracted position in relation to the body.
  • the locking bolt is provided with two annular grooves.
  • An axially rotatable plug is arranged in the body, which is arranged to engage one of the annular groves through axial rotation, to provide an axial locking of the locking bolt in said retracted position. In the retracted position of the locking bolt, the roller shutter is locked by the locking bolt.
  • US 4 565 078 discloses a locking assembly for a gate locking system, comprising a housing assembly, a locking bolt axially slidable between two end positions against the action of a spring, and an axially slidable lug arranged in the housing assembly.
  • the locking bolt is provided with one recess, and the lug is arranged to engage said recess, to provide an axial locking of the locking bolt in one of the end positions.
  • Said spring is arranged to bias the locking bolt to its unlocked position.
  • WO 99/04118 describes a locking arrangement for sliding shutters, comprising a lock body and a locking bolt axially slidable between two end positions.
  • the locking bolt is provided with a first and a second recess, and a ball is arranged to engage each recess to provide an axial locking of the locking bolt in one of the end positions.
  • the object of the present invention is therefore to provide a locking device for sliding shutters or rolling shutters, which improves the burglar-proof character, is well protected towards external damaging action, is easy to produce, install and handle, and offers a wide flexibility regarding the choice of position of installation when applied on rolling shutters or sliding shutters.
  • a locking device for sliding shutters, or rolling shutters of the kind defined in the preamble of claim 1, where the locking device comprises the special features that the locking bolt is axially slidable against the action of a spring means, the spring means being arranged to urge the locking bolt towards said protruding position, that the locking bolt is arranged to engage the first recess through axial rotation, to provide an axial locking of the locking bolt in said protruding position, and that the locking bolt in said protruding position is arranged to engage said sliding shutter by means of its end portion disposed at the second recess, for the locking of said sliding shutter.
  • This locking device provides a secure and stable locking of a sliding shutter when the locking bolt is in the protruding position and engages a recess in the sliding shutter. There is no need for any additional locking mechanism arranged outside the lock housing, which provides a secure construction protected from external damaging action. Since the whole locking mechanism is disposed in one and the same lock housing, the locking device is also easy to install at any position along the sliding shutter, but suitably the locking device is positioned along the guiding means of the sliding shutter, so that the locking bolt in its protruding position engages the sliding shutter and mechanically prevents the sliding of the sliding shutter. Further, the locking device according to the invention is easy to produce and has few loose parts, which provides for a durable construction, and is easy to handle.
  • the locking bolt By locking the locking bolt also in a retracted position, the locking bolt is prevented from accidentally protrude from the lock housing.
  • the locking bolt is automatically protruded from the lock housing in its displaceable position by the action of said spring means, and thereafter the locking bolt is locked in a protruding position.
  • unlocking the sliding shutter firstly the locking bolt is disengaged by rotation of the locking pin, and subsequently the locking bolt is manually pushed into the lock housing, and thereafter the locking pin is again axially rotated to lock the locking bolt in a retracted position
  • each of the first and second recesses comprises an annular groove.
  • the mantle of the locking pin is provided with a recess having a shape corresponding to the outer surface of the locking bolt, the locking bolt being arranged to axially slide in said recess, in its displaceable, unlocked position.
  • each recess has a shape corresponding to the mantle of the locking pin.
  • the locking pin is substantially circular cylindrical.
  • the locking bolt is substantially circular cylindrical.
  • the locking pin is controllable by a lock cylinder, into which a key is inserted, and the axial rotation of the locking pin is controlled by the rotation of the key.
  • Fig. 1 shows an embodiment of the locking device according to the present invention seen from the side where the lock housing 1 is beveled to prevent external damaging action, and is cast from aluminium.
  • a circular cylindrical locking bolt 2 and an axially rotatable circular cylindrical locking pin 3 are arranged in the lock housing 1 in the lock housing 1 against the action of a spring means 5 between a protruding position and a retracted position in relation to the lock housing 1.

  • the locking pin 3 is engaged with the first annular groove 6, and through this the locking bolt 2 is locked in a protruding position, whereby the external end of the locking bolt is protruding from the lock housing and can engage a sliding shutter.
  • the locking pin 3 In order to lock the locking bolt 2 in a retracted position, the locking pin 3 is disengaged from its engagement with the first annular groove 6, whereby the locking bolt 2 can be axially displaced and thus pushed into the lock housing 1 so that the second annular groove 7 is positioned at the locking pin 3.
  • a lock ring stop 8 is arranged at the external end of the locking bolt 2, which also prevents the locking bolt 2 from further retraction into the lock housing 1, since the lock ring stop 8 will abut on the front side of the lock housing 1, and in this position of the lock ring stop 8, the second annular groove 7 is positioned in a position engageable by the locking pin 3.
  • Fig. 2 is a schematic sectional front view of the embodiment of the locking device of Fig. 1.
  • the mantle of the locking pin 3 is provided with a recess having a shape corresponding to the outer surface 9 of the locking bolt 2, the locking bolt 2 being arranged to axially slide in the recess, in its displaceable, unlocked position.
  • the locking pin 3 is arranged to engage an annular groove by axial rotation, to provide the axial locking of the locking bolt 2.
  • the axial rotation of the locking pin 3 providing the axial locking of the locking bolt 2, as the locking pin 3 engages with the annular groove of the locking bolt 2, can for example be about 180°, whereby the recess of the locking pin 3 is entirely turned away from the locking bolt 2.
  • a lock cylinder 10 is attached, into which a key is inserted to control the locking pin 3.
  • a mounting hole 11 is also seen, for installation of the lock cylinder 10 by means of a hardened mounting screw 12 being inserted into the mounting hole 11 and attached to the lock cylinder 10. Subsequently, the mounting hole 11 can be sealed by driving in a steel ball.
