Nut and method for fixing an object to a building structure

1. A nut ( 10 ), comprising:

a female thread ( 34 ) for threading a bolt ( 14 ) thereinto;

a head ( 52 ) surrounding said female thread ( 34 ), for holding said female thread ( 34 ), for allowing rotating the bolt ( 14 ) in relation to said female thread ( 34 ); and

a self-tapping thread ( 36 ), for threading said nut ( 10 ) through an object ( 18 ), said self-tapping thread ( 36 ) characterized in not providing linear pacing in relation to the object ( 18 ) upon rotation therebetween upon completing the threading therebetween,

wherein said self-tapping thread ( 36 ) comprises said female thread ( 34 ) for threading the bolt ( 14 ) therethrough,

thereby allowing connecting said nut ( 10 ) to the object ( 18 ) and then moving the bolt ( 14 ) in relation to the object ( 18 ) either by rotating the bolt ( 14 ) in relation to said nut ( 10 ), or by rotating said nut ( 10 ) in relation to the object ( 18 ),

thereby allowing fixing the object ( 18 ) to a building structure ( 20 ) at an adjustable distance ( 40 ), and

wherein said character of said self-tapping thread ( 36 ) of not providing linear pacing in relation to the object ( 18 ) upon rotation therebetween upon completing the threading therebetween, comprises an internal binding ( 44 C) being thinner than the other bindings ( 44 B),

thereby upon rotating said nut ( 10 ) in relation to said object ( 18 ) in a closing direction ( 64 ), a bending ( 88 ) in a hole ( 54 ) in said object ( 18 ) bends an end ( 90 ) of said internal binding ( 44 C),

thereby removing said bending ( 88 ) of said object ( 18 ) from a gap ( 86 ) between the bindings ( 44 B, 44 C) of said self tapping thread ( 36 ).

2. A tool ( 60 )

for rotating a bolt ( 14 ) threaded into a nut ( 10 ) upon rotating to a closing direction ( 64 ), and

for releasing the bolt ( 14 ) therefrom upon rotating to an opening direction, said tool ( 60 ) comprising:

a first female thread ( 62 ), for threading a male thread ( 66 ) of the bolt ( 14 ) thereinto; and

a tightening element ( 32 ) pressing the male thread ( 66 ) of the bolt ( 14 ) outside from said female thread ( 62 ),

thereby providing friction therebetween,

wherein said nut ( 10 ) comprises:

a female thread ( 34 ) for threading the bolt ( 14 ) thereinto;

a head ( 52 ) surrounding said female thread ( 34 ), for holding said female thread ( 34 ), for allowing rotating the bolt ( 14 ) in relation to said female thread ( 34 ); and

a self-tapping thread ( 36 ), for threading said nut ( 10 ) through an object ( 18 ), said self-tapping thread ( 36 ) characterized in not providing linear pacing in relation to the object ( 18 ) upon rotation therebetween upon completing the threading therebetween,

wherein said self-tapping thread ( 36 ) comprises said female thread ( 34 ) for threading the bolt ( 14 ) therethrough,

thereby allowing connecting said nut ( 10 ) to the object ( 18 ) and then moving the bolt ( 14 ) in relation to the object ( 18 ) either by rotating the bolt ( 14 ) in relation to said nut ( 10 ), or by rotating said nut ( 10 ) in relation to the object ( 18 ),

thereby allowing fixing the object ( 18 ) to a building structure ( 20 ) at an adjustable distance ( 40 ), and

wherein said character of said self-tapping thread ( 36 ) of not providing linear pacing in relation to the object ( 18 ) upon rotation therebetween upon completing the threading therebetween, comprises a space ( 48 ) between an internal binding end ( 90 ) of said self-tapping thread ( 36 ) and an adjacent surface ( 38 ) of said nut ( 10 ), said space ( 48 ) being substantially larger than a thickness ( 84 ) of the object ( 18 ), for allowing the object ( 18 ) rotate within said space ( 48 ).

3. A tool ( 60 ) according to claim 2 , further comprising:

a male thread ( 42 ), for pressing said tightening element ( 32 ); and

a second female thread ( 68 ) fitting to said male thread ( 42 ), wherein paces ( 70 ) of said male ( 42 ) and second female ( 68 ) threads are significantly greater than a pace of the thread ( 66 ) of the bolt ( 14 ),

thereby opening said male thread ( 42 ) from said second female thread ( 68 ) for releasing said tightening element ( 32 ), before opening the bolt ( 14 ).
