Abstract
Abstract A fastening device comprises a pin-shaped fastener having an axis, and means for tightening and loosening the fastener, the tightening and loosening unit including one element provided with first connecting means for connecting the one element with the fastener and also provided with second connecting means, and another element provided with third connecting means cooperating with the second connecting means of the one element for connecting the other element with the one element, so that when a rotary force is applied to at least one of the elements, the elements are shifted coaxially in opposite axial directions and the fastener is displaced in an axial direction.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
120 words
A fastening device, comprising a pin-shaped fastener having an axis; and means for tightening and loosening said fastener, said tightening and loosening means including a first element provided with first connecting means for connecting said first element with said fastener and also provided with second connecting means, a second element provided with third connecting means cooperating with said second connecting means of said first element, said elements being formed to interact so that when at least one of said elements which does not turn on an object located outside the fastening device is turned, said elements are shifted coaxially in opposite axial directions without turning in a thread of said fastener and said fastener is displaced in an axial direction.
Claim 2
Dependent Claim
120 words
A fastening device, comprising a pin-shaped fastener having an axis; and means for tightening and loosening said fastener, said tightening and loosening means including a first element provided with first connecting means for connecting said first element with said fastener and also provided with second connecting means, a second element provided with third connecting means cooperating with said second connecting means of said first element, said elements being formed to interact so that when at least one of said elements which does not turn on an object located outside the fastening device is turned, said elements are shifted coaxially in opposite axial directions without turning in a thread of said fastener and said fastener is displaced in an axial direction.
Claim 3
Dependent Claim
65 words
A fastening device as defined in claim 1, wherein said first element has a first part provided with said first connecting means connecting said first part of said first element with said fastener, and a second part which is rotatably connected with said first part and provided with said second connecting means for connecting said second part of said first element with said second element.
Claim 4
Dependent Claim
46 words
A fastening device as defined in claim 1; and further comprising locking means arranged so that when said fastener is displaced in an axial direction and the desired elongation of said fastener is achieved, said locking means is locked to said fastener to retain said elongation.
Claim 5
Dependent Claim
18 words
A fastening device as defined in claim 3, wherein said locking means is arranged in said second element.
Claim 6
Dependent Claim
39 words
A fastening device as defined in claim 3, wherein said locking means is arranged so that when it is locked to said fastener, said first element can be removed and then said locking means continues to retain said elongation.
Claim 7
Dependent Claim
108 words
A tightening and loosening unit for a pin-shaped fastener having an axis, comprising a first element provided with first connecting means for connecting said first element with said fastener and also provided with second connecting means; a second element provided with third connecting means cooperating with said second connecting means of said first element, said elements being formed to interact so that when at least one of said elements which does not turn on an object located outside the unit is turned, said elements are shifted coaxially in opposite axial directions without turning in a thread of said fastener and said fastener is displaced in an axial direction.
Claim 8
Dependent Claim
108 words
A tightening and loosening unit for a pin-shaped fastener having an axis, comprising a first element provided with first connecting means for connecting said first element with said fastener and also provided with second connecting means; a second element provided with third connecting means cooperating with said second connecting means of said first element, said elements being formed to interact so that when at least one of said elements which does not turn on an object located outside the unit is turned, said elements are shifted coaxially in opposite axial directions without turning in a thread of said fastener and said fastener is displaced in an axial direction.
Claim 9
Dependent Claim
66 words
A tightening and loosening unit as defined in claim 6, wherein said first element has first part provided with said first connecting means connecting said first part of said first element with said fastener, and a second part which is rotatably connected with said first part and provided with said second connecting means for connecting said second part of said first element with said second element.
Claim 10
Dependent Claim
48 words
A tightening and loosening unit as defined in claim 6, and further comprising locking means arranged so that when said fastener is displaced in an axial direction and the desired elongation of said fastener is achieved, said locking means is locked to said fastener to retain said elongation.
Claim 11
Dependent Claim
20 words
A tightening and loosening unit as defined in claim 8, wherein said locking means is arranged in said second element.
Claim 12
Dependent Claim
41 words
A tightening and loosening unit as defined in claim 8, wherein said locking means is arranged so that when it is locked to said fastener, said first element can be removed and then said locking means continues to retain said elongation.
