Definitions

  • the present invention relates to an antipanic pushbar for mortice locks.
  • the present invention relates to an antipanic pushbar of the type comprising a horizontal bar adapted to rotate when pushed in order to open a lock.
  • Panic pushbars are subject to stringent standards as regards dimension, and in particular to a maximum limit that the horizontal bar is permitted to project when in lock closed position to prevent obstructing any transit, and to a minimum limit that the horizontal bar is permitted to project when in lock open position to prevent injury to the hands and fingers of the user activating the device.
  • the technical aim of the present invention therefore, is to provide an antipanic pushbar for mortice locks that eliminates the technical problems present in state of the art systems.
  • one aim of the invention is to create an antipanic pushbar for mortice locks that remains within the dimensional limits established by current standards, while providing high rotation torque at the same time, reducing internal friction to a minimum in order to prolong its working life as well as permitting its use with a lock with several locking points, in other words, locks that require high torque on the pushbar spindle.
  • Another aim of the present invention is to provide an antipanic pushbar for mortice locks having a single type of pushbar spindle mechanism action that can operate whether positioned on the left or right hand side of the lock in order to reduce pushbar costs considerably.
  • Yet another aim of the present finding is to provide an antipanic pushbar for mortice locks that is safe and reliable.
  • the last aim, but by no means the least, is to provide an antipanic pushbar for mortice locks with an extremely compact and simple mechanism, able to perform for a long period.
  • an antipanic pushbar for mortice locks characterised in that it comprises a lock plug that rotates and is fixed to the spindle of said pushbar, and a first and a respectively second element to actuate said lock plug fixed to and rotating on said pushbar and engaged to act against a first and respectively second strike plate of said lock plug with a first and respectively second force of rotation in a same direction, and applied on the opposite side of the hinge pin of said pushbar in order to generate a same first and respectively second rotation moment adapted to rotate said lock plug from the closed position to the open position of the lock.
  • an antipanic pushbar for mortice locks is identified throughout with the reference numeral 1.
  • Pushbar 1 comprises a horizontal bar 2 supported at opposite ends by two brackets 3, each of which is operationally fixed to a corresponding plate 4 for attachment to the lock (not shown).
  • pushbar 1 comprises a rotation pin 12 that is supported by opposed lugs 5 that both extend at right angles to a corresponding fixing plate 4.
  • One of the plates 4 includes a template 14 that can be overlaid on the keyhole of the lock for key insertion.
  • Pushbar 1 comprises a lock plug 6 fixed to and rotating on the spindle (not shown) of pushbar 1, and a first and respectively second actuator element of lock plug 6 fixed to and rotating on pushbar 1 and engaged to act against first - and second striker plates 8 and 7 respectively of lock plug 6.
  • Lock plug 6 comprises a seat 10 axially set for pushbar 1 spindle insertion.
  • lock plug 6 has a cylindrical form.
  • first and respectively second actuators act against the first and respectively second strike plates 8 and 7 of lock plug 6 with a first and respectively second force of rotation in a same direction and applied on the opposite side of the hinge pin 12.
  • first and respectively second actuator elements generate a first and respectively second same moment of rotation adapted to rotate the lock plug 6 from the closed position of the lock to open position.
  • the first and respectively second actuators are formed by first and respectively second pins 11 and 13 aligned with each other.
  • first and respectively second pins 11 and 13 are aligned and coplanar with the hinge pin 12 of pushbar 1.
  • the first and respectively second strike plates 8 and 7 are obtained from a first and respectively second release mechanism of the lock plug 6 in which the first and respectively second pins 11 and 13 perform a sliding action.
  • the first and respectively second release mechanisms are crosswise to the axis of lock plug 6 and extend at an angle along a first and respectively second sector of the side surface of the lock plug 6 in an axially and offset manner.
  • the lock plug 6 also comprises a third release mechanism 9 inside which slides the hinge pin 12.
  • the third release mechanism 9 is also set crosswise to the lock plug axis and extends at an angle along a third sector of the side surface of lock plug 6 axially interposed between the first and second sector and at least partially overlaid on the first and second sector in an angular manner.
  • the second release mechanism forms a closed slot along the side surface of lock plug 6
  • the third release mechanism forms two closed symmetrical slots along the side surface of lock plug 6, while the first release mechanism forms an open slot directly on the end of lock plug 6 opposite to the end that engages the spindle.
  • the preferred embodiment shows a pushbar that produces a spindle rotation of 30°. Naturally it is understood that it is possible to produce rotations other than 30°.
  • the first and respectively second sectors are angularly and symmetrically opposite each other while the third sector is angularly and symmetrically overlaid between the first and respectively second sector.
  • first and respectively second sectors extend along the side surface of the lock plug 6 with an angle that is wider than 180° while the third sector extends with an angle of approximately 60°.
  • the contact point of the first and respectively second actuators with the first and respectively second strike plates when the pushbar 1 is in lock closed position should be located at the radially external limit of lock plug 6 in order to obtain the maximum leverage possible for the first and respectively second force of rotation.
  • first and respectively second release mechanisms comprise a first and respectively second flat contact surface 17 and 20 with a first and respectively second flattened portion 19 and 18 of the side surface of the first and respectively second pins 11 and 13.
  • the first and respectively second flat portions 17 and 20 are aligned with the first and respectively second flattened portions 19 and 18 of the side surface of the first and respectively second pins 11 and 13 when the pushbar 1 is in the lock open position, and not aligned when the pushbar is in lock closed position.
  • the extended flat contact surfaces between the first and second pins and the relative strike plates limits the contact pressure between the parts thus preserving them from rapid wear:
  • the spindle insertion seat 10 comprises a plurality of offset spindle indentations at an angle in order to connect lock plug 6 with the spindle in a selective manner in one of the plurality of relative angular positions.
  • the spindle insertion seat 10 comprises at least a first and a second indentation that is rotated at a 30° angle compared to the first indentation.
  • Pushbar 1 also comprises arrest means in its closed and open lock positions.
  • Such arrest means comprise a first and respectively a second pair of opposite slots 16 and 15 respectively cut in the opposite lugs 5 in which the ends of the first and respectively second pins 11 and 13 perform slide action and are supported.
  • the safety aspect of the pushbar of the present invention is considerable.
  • the arrest means described above provide four distinct end of run limits in lock open position and four distinct start of run limits in lock closed position.
  • the pushbar 1 function according to the invention is made very clear by the description and illustrations, and in particular the basic concept is conceived as follows.
  • lock plug 6 is activated by two rotation torques in the same direction and of the same strength.
  • Lock plug 6 activates the rotation of the pushbar 1 spindle that controls the retraction of the latch bolt and therefore the opening of the lock.
  • a return spring acts on the spindle that activates the lock plug 6 in counter-rotation returning it to the lock closed position.
  • the pushbar divides the user's thrust into two forces of rotation applied in a wide leverage and from the opposite side in relation to the rotation pin, in a manner so that the total rotation torque results as very strong, even though the single rotation forces are of relatively limited strength.
  • the pushbar will perform for a long working life, and is adapted to be applied to locks with more than one locking point.
  • the same spindle mechanism action of the pushbar can be used in spite of whether the latch bolt is located on the right hand or left hand side of the lock.
  • the spindle is inserted in its first indentation when the latch-bolt is on the right hand side of the lock, but inserted in its second indentation rotated to 30° compared to the first indentation, when the latch-bolt is on the left hand side of the lock.
  • the spindle return spring to lock closure position and the rest of the mechanism can be positioned at the opposite ends of the pushbar.
  • the materials employed,as well as their size could be of any kind according to needs and technical conditions.
