Patent number: 9550237Abstract: A tool arrangement and chuck apparatus for quick change of a range of tools; particularly, a quick change chuck adapted to engage various diameter drill bits, tools and tool holders. The tools are rotatable in a chuck or adaptor and have at one end a centering shaft portion having a constant diameter for multiple tool end diameters and shapes, a drive shoulder portion and a lock portion. The chucks have a tool centering arrangement for accommodating the constant diameter centering shaft. The chucks are also described as having tool bit release mechanism operable to disengage the tool from a retention mechanism when a force is applied inwards of the body of the chuck by the user to allow the tool bit to be removed longitudinally from the chuck but also arrange to allow the tool bit to be inserted longitudinally into the chuck without requiring any other user operation.Type: GrantFiled: April 23, 2012Date of Patent: January 24, 2017Inventor: Kym Keightley

Publication number: 20080050189Abstract: The present invention relates to an improved hole-saw assembly and in particular, to a mandrel engageable by a drill and including at least one locking ring or annulus that allows for the base of two hole-saws of different diameter to be quickly and easily mountable and demountable from the mandrel. The hole-saw assembly includes a first hole-saw having a base that includes a pair of drive-pins extending outwardly therefrom and a pair of apertures for insertion therethrough of the drive pins of a second hole-saw. The drive pin pairs are then inserted through corresponding apertures in the mandrel to engage an annulus coupled to the mandrel. The present invention provides for each drive pin to be engaged by the annulus despite the difference in longitudinal length of the drive pins beyond the base of the first hole-saw. The hole-saws are snap-fit within the annulus and may be disengaged by simply rotating the annulus to a second position.Type: ApplicationFiled: September 14, 2007Publication date: February 28, 2008Inventor: Kym Keightley

Publication number: 20080019785Abstract: A hole-saw assembly including a hole-saw having at one end a plurality of cutting teeth and at the other end two shafts. The assembly includes a mandrel coaxially aligned with said hole-saw and including a body having two bores therethrough coaxially aligned with said shafts. An annulus located on top of the body is coaxially aligned with said mandrel and hole-saw and includes two holes, the annulus rotatable around its longitudinal axis from a first to a second position. In the first position, the annulus holes are aligned with the bores and shafts allowing the shafts to be freely insertable and removable and in the second position the holes are misaligned to lock the shafts to the annulus. Such an arrangement allows the hole-saw and the mandrel to be easily and quickly mountable and demountable.Type: ApplicationFiled: September 7, 2007Publication date: January 24, 2008Inventor: Kym KEIGHTLEY

Publication number: 20070036620Abstract: The present invention relates to an improved hole saw boss (10) and in particular, to a boss including a threaded member (12) adapted to accommodate two hole saws of the same or different bore thread diameters. The present invention allows for a pre-existing aperture (22) in a work piece to be simply enlarged. This is useful if a new lock mechanism is being installed in a door with a pre-existing aperture where the lock mechanism requires a larger aperture than that which was in existence. Currently the aperture has to be enlarged by manual handwork since there is no centre-point to which a pilot drill may be enlarged. The threaded bore diameters of the present invention correspond with the commonly available hole saw threaded bore diameters. The present invention therefore provides the public with device for enlarging apertures which is simply, cost effective and can be used with currently available hole saws.Type: ApplicationFiled: March 26, 2004Publication date: February 15, 2007Inventor: Kym Keightley

Publication number: 20060144102Abstract: The present invention relates to a dual lock apparatus (10) of the type including a locking bolt (14) moveable between a first locked position and a second unlocked position said bolt movement corresponding with longitudinal movement of a slider (26) said apparatus including a first and a second locking means adapted to operate independently of one another. The first locking means (74) includes a rotatable cam (76) such that when rotated said cam acts against a moveable piston to thereby move said piston from a first position to a second position in which the second locking means becomes disengaged from said slider and further rotation of the cam urges longitudinal movement of the slider.Type: ApplicationFiled: December 1, 2003Publication date: July 6, 2006Applicant: Inovec Pty Ltd.Inventor: Kym Keightley

Publication number: 20050127684Abstract: A deadlocking assembly for use in locks that includes a rack supporting a bolt and a driving or pinion gear that drives the rack. Both the rack and the pinion gear have teeth that intermesh. The pinion gear further includes two arms, one of which acts as a stop when extending the bolt and the other that acts as a deadlock. When in the deadlocked position, forcing of the bolt is prevented by the other arm since the pinion gear teeth and the rack gear teeth at that position do not intermesh. A tab is further used to limit further rotation of the pinion gear.Type: ApplicationFiled: December 10, 2003Publication date: June 16, 2005Inventor: Kym Keightley
