Definitions

  • the subject of the present invention is a lock for closures in general (e.g. doors tilting, curtains, roller shutters and others) of cylinder type, in which the cylinder block of the lock is of a unified type with twist bit, known in the art in this field as "cylinder European”.
  • Document EP 0.434.635 A describes a lock for closures, comprising a cylinder block with a rotating member, and including a wheel central cog which controls two side cog wheels which in turn control locks, said central gear being a crown with external teeth surrounding the cylinder block, rotatably mounted according to a axis and having two teeth directed inwards which limit a notch likely to be engaged by the rotating member, along a limited arc which corresponds to part of a turn of the rotating member, the two positions extremes of engagement between the ring gear and the corresponding rotating member at the two extreme positions, opening and closing respectively, locks controlled by the side toothed wheels.
  • a first object of the present invention is to provide a lock for overhead doors, curtains, roller shutters and the like, making use of a unified type cylinder block with rotating bit, called European cylinder, whose structure must be particularly simple, economical and reliable.
  • An object of the invention is also to produce such a lock in which the mechanisms for moving the locks must be intrinsically irreversible compared to an external order.
  • an object of the invention is to produce such a lock whose actuation must request only one turn of the key, and it must not prove to be impossible even if, due to an accident, the locks are worn in a position incorrect.
  • a further aim of the invention is to produce such a lock which, in cases where this is requested, and without causing complications of the structure, can be operated from the inside without using the key, and / or by motorized means, whether the key is inserted in the cylinder or not.
  • Another object of the invention is to produce such a lock which is capable of being easily mounted by mechanized equipment.
  • each side gear wheel controls a lock by means of an eccentric pivot engaged in a slot in the lock, which extends perpendicular to the direction of movement of the lock and has a limited length on one side at the axis of rotation of the toothed wheel.
  • the distance of said eccentric pivot from the axis of rotation of the side gear is equal to the half of the bolt stroke between position opening and closing position.
  • the side gears (and therefore also the central gear which is meshed with they) are always stopped at the end of the race in a defined position, in which said pivots eccentric and the axes of rotation of the gears are all in line, at least in one way approximate, along the direction of travel of locks, so they're in one condition neutral point which ensures the irreversibility of the moving locks under actions different from those of the actuating toothed wheels.
  • the pivoting of the gears obtained by means of protruding sectors partially sheared in the lock box, in engagement with internal cylindrical surfaces of the gear wheels, reduces manufacturing costs by avoiding use, machining and the mounting of pivots, and allows to leave free the internal space of the wheel central tooth, space which must be occupied by the cylinder block.
  • the cover of the lock is fixed to the box of the lock by means acting by means of a plastic deformation of some parts of the box or cover. This also reduces the costs of manufacturing and machining the lock.
  • the springs arranged to act between the latches and the eccentric pivots of the lateral toothed wheels stabilize them the end positions and give the user a sensitive perception when said positions are reached.
  • these springs have not an operative function, so their possible rupture or nervousness does not prejudge the functioning of the lock.
  • the lock includes a box 1 which contains the mechanisms and which is closed by a cover 20.
  • the box 1 and cover 20 are provided with openings 2 and 21 respectively, shaped like a cylinder block of the so-called European type, and intended to receive such a block (which is shown in Figures 1 and 2 only by its periphery corresponding to the opening 2).
  • the box 1 also has an opening 3 for the passage of a screw intended to fix in the box the cylinder block 2, in the usual way.
  • holes 4 for fixing to the overhead door, curtain or other closure intended to be fitted by the lock.
  • each lock 8 is provided close to its outer end of a pivot 10 intended to be connected to the curtain locking means or the like to order them.
  • each lock 8 is provided with a slit 11 perpendicular to the direction longitudinal movement of the bolt, to receive the command.
  • Each lock is controlled by a gear wheel lateral 12 provided with a central hole 13 on the surface cylindrical for its pivoting in the box 1.
  • the pivoting is achieved by means of sectors 7 (in number of three in the example shown) partially sheared towards the inside of the walls of the box 1. These partially sheared sectors have an outer circumference in an arc of a circle and give correct support with freedom of rotation to the wheel corresponding side tooth 12, cooperating with the cylindrical surface of hole 13. Such an arrangement avoids the application of pivots to box 1.
  • Each side gear 12 has a pivot stamped 14 capable of engaging the slot 11 of a lock 8. This arrangement constitutes a crank capable of to control the movements of the lock.
  • the distance radial of a stamped pivot 14 relative to the center of the side gear 12 to which it belongs is equal to half the travel provided for lock 8 corresponding; in this way, a 180 ° rotation of the side gear 12 in one direction or the other causes the corresponding bolt 8 to complete its stroke whole opening or closing.
  • the slot 11 of latch 8 ends on one side at the center of the corresponding side gear 12, of so that it limits the rotation stroke to the angle of 180 ° which is necessary.
  • the two lateral toothed wheels 12 engage both with a central gear which consists of a crown with external teeth 15 mounted in the center O 'of the lock and surrounding the seat for cylinder block 2, and therefore the block itself when it is installed in the lock.
  • the crown 15 has a cylindrical inner surface 16 for its pivoting relative to the box 1.
  • the pivoting is achieved by means of sectors 6 (in number of four in the example shown) partially sheared towards the inside of the walls of the box 1. These partially sheared sectors have an outer circumference in an arc of a circle and give correct support with freedom of rotation to the wheel central tooth 15, cooperating with its surface internal cylindrical 16.
  • the ring gear 15 has two teeth 17 projecting towards the interior, which define a notch 18 likely to engage the turning bit from block to block cylinder installed in the lock, the trajectory of which of rotation is indicated in figure 1 by the circle C whose center is O. It should be noted that the wheel central tooth 15 is not coaxial with circle C which represents the trajectory of the bit, the two centers of rotation O 'and O not being coincident.
  • the lock according to the invention does not require necessary no spring, which contributes in considerable measure of its reliability. Nevertheless, one or several springs 19 can be installed, such as the show Figures 1 and 2, to act between at least one of the locks 8 and the pivot 14 of the toothed wheel side 12 which controls the lock itself.
  • a spring thus arranged gives the user a confirmation sensitive to the fact that the end position of the locks has been successfully reached. Furthermore she tends to keep this end position stable even in the presence of accidental stress, such as shock or vibration. However, the break possible or the nervousness of this spring does not prejudge in no way of the functionality of the lock.
  • the invention also provides a preferred means of fixing the cover 20 to the box 1.
  • the side walls of the box 1 have notches, each which is provided with a tongue 5.
  • a additional conformation of the cover 20 allows place the latter on the box and then fix by plastic deformation of the tabs 5.
  • the notches provided in the side walls of the box 1 could be provided lateral digging, and tabs cover correspondents could be anchored in these excavations by means of a deformation plastic such as to produce an enlargement.
