Window securing means and methods
An assembly for securing an openable aperture closure member ( 11 ) in closed position relative to an aperture defines by a main frame ( 12 ), the aperture closure member ( 11 ) including a mechanically rotational element ( 24, 44, 54 ) for securing said closure member ( 11 ) to the frame ( 12 ), the assembly for securing comprising a push and/or pull actuation assembly ( 35 ) for easing the securing and/or releasing process for the aperture closure member, the actuation assembly including a handle bar ( 26 ) and at least one connecting member ( 37 ) which operably connects the handle bar ( 36 ) to the mechanical element ( 24, 44, 54 ); wherein the push and/or pull actuation assembly ( 35 ) is adapted to be translationally movable by an operator and the connecting member ( 37 ) is adapted to convert translational movement of the actuation assembly ( 35 ) into rotational forcing movement of the mechanically rotational element ( 24, 44, 54 ).
1. An assembly for securing an openable aperture closure member ( 11 ) in a closed position relative to an aperture defined by a main frame ( 12 ), comprising:
a rotatable magnetic field element ( 24 ) for securing said closure member ( 11 ) to the frame ( 12 ); and
a push and/or pull actuation assembly ( 35 ) for easing the securing or releasing process for the aperture closure member, the actuation assembly including a handle bar ( 36 ) and at least one connecting member ( 37 ) which operably connects the handle bar ( 36 ) to said rotatable magnetic field element ( 24 );
wherein said handle bar ( 36 ) is translationally movable by an operator and translational movement of the handle bar moves the connecting member ( 37 ) to generate rotational movement of said rotational magnetic field element ( 24 );
wherein said rotatable magnetic field element ( 24 ) is rotatable within a substantially stationary magnetically conductive element ( 21 , 22 ), the rotatable magnetic field element ( 24 ) being cooperative with said stationary magnetically conductive element ( 21 , 22 ) to alternately create and eliminate a magnetic field to co-act with a magnetically attractive fixture element ( 42 ) positioned on the frame ( 12 ) to alternately hold and release said closure member ( 11 ) relative to the stationary frame ( 12 );
wherein the rotatable magnetic field element ( 24 ) is adapted to be operably engaged by a gear-toothed activation member ( 28 ) which is adapted to operably transmit forcing movement to the rotatable magnetic field element ( 24 ).
2. An assembly for securing according to claim 1 characterized in that the substantially stationary magnetically conductive element ( 21 , 22 ) includes a substantially stationary magnetic field element ( 21 , 22 ), the rotatable magnetic field element ( 24 ) being rotatable within the substantially stationary magnetic field of the substantially stationary magnetic field element ( 21 , 22 ), the rotatable and stationary magnetic fields of the respective rotatable magnetic field element ( 24 ) and the substantially stationary magnetic field element ( 21 , 22 ) being cooperative with each other to alternately securely hold, and then release the closure member ( 11 ) with respect to the stationary frame ( 12 ).
3. An assembly for securing according to claim 1 characterized in that the substantially stationary magnetically conductive element ( 21 , 22 ) includes one of one or two members ( 21 , 22 ), wherein two members are separated by a non-magnetically conductive layer.
4. An assembly for securing according to claim 1 wherein the substantially stationary magnetically conductive element ( 21 , 22 ) includes one of one or two substantially stationary permanent magnetic elements ( 21 , 22 ).
5. An assembly for securing according to claim 1 wherein the rotatable magnetic field element ( 24 ) is a rotatable permanent magnet ( 24 ).
6. An assembly for securing according to claim 1 characterized by further comprising an auxiliary rotational locking means ( 44 , 54 ) for locking the closure member ( 11 ) to the frame ( 12 ).
