Abstract
Abstract A tool is provided for securing a fastening device in the shape of an outer clamping sleeve member with an internal thread, and an inner clamping sleeve member with an external thread, said clamping sleeve members being mutually rotatable. Wrench mounts are provided on the device, such as teeth and slots, and the securing tool, which is complementary, is inserted to engage the teeth and slots for mutual turning of the clamping sleeve members. A lock pin is also disclosed, which is received in adjacent slots of the sleeve members to prevent movement of one relative to the other.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
176 words
A tool for tightening a fastening device including an inner clamping sleeve member with an external thread and an outer clamping sleeve member with an internal thread, the outer clamping sleeve member coaxially encompassing the inner clamping sleeve member, and each clamping sleeve member including a wrench mount located at the same side of the device and including a plurality of teeth with intermediate slots, the tool comprising: two mutually movable tool members wherein said two tool members include an inner tubular socket spanner and an outer tubular socket spanner, which are coaxially arranged and are mutually rotatable, wherein each spanner has a plurality of teeth spaced to be insertable into said wrench mount slots, the number of teeth on one of the spanners being different than the number of teeth on the other spanner, to transfer force momentum in a common plane perpendicular to a central longitudinal axis common to the sleeves of said fastening device and said spanners, and wherein mutual rotation of said spanners rotates said inner and outer clamping sleeve members, respectively.
Claim 2
Dependent Claim
176 words
A tool for tightening a fastening device including an inner clamping sleeve member with an external thread and an outer clamping sleeve member with an internal thread, the outer clamping sleeve member coaxially encompassing the inner clamping sleeve member, and each clamping sleeve member including a wrench mount located at the same side of the device and including a plurality of teeth with intermediate slots, the tool comprising: two mutually movable tool members wherein said two tool members include an inner tubular socket spanner and an outer tubular socket spanner, which are coaxially arranged and are mutually rotatable, wherein each spanner has a plurality of teeth spaced to be insertable into said wrench mount slots, the number of teeth on one of the spanners being different than the number of teeth on the other spanner, to transfer force momentum in a common plane perpendicular to a central longitudinal axis common to the sleeves of said fastening device and said spanners, and wherein mutual rotation of said spanners rotates said inner and outer clamping sleeve members, respectively.
Claim 3
Dependent Claim
24 words
A tool according to claim 1, wherein each of said spanners includes a wrench mount for cooperation with means for mutually moving said spanners.
Claim 4
Dependent Claim
20 words
A tool according to claim 2, wherein each of the wrench mounts on the respective spanners has the same dimensions.
Claim 5
Dependent Claim
30 words
A tool according to claim 1, wherein the width of each of said teeth on a spanner is substantially equal to the distance between adjacent teeth on the same spanner.
Claim 6
Dependent Claim
19 words
A tool recited in claim 1, wherein each of said spanners includes a means for mutually moving said spanners.
Claim 7
Dependent Claim
22 words
A tool as recited in claim 5, wherein the means for mutually moving said spanners includes a handle attached to each spanner.
Claim 8
Dependent Claim
151 words
A tool for tightening a fastening device including an inner clamping sleeve member with an external thread and an outer clamping sleeve member with an internal thread, the outer clamping sleeve member coaxially encompassing the inner clamping sleeve member, and each clamping sleeve member including a wrench mount located at the same side of the device and including a plurality of teeth with intermediate slots, the tool comprising: an inner tubular socket spanner having a handle and an outer tubular socket spanner having a handle, which are coaxially arranged and are mutually rotatable, wherein each spanner has a plurality of teeth spaced to be insertable into said wrench mount slots, to transfer force momentum in a common plane perpendicular to a central longitudinal axis common to the sleeves of said fastening device and said spanners, and wherein mutual rotation of said spanners rotates said inner and outer clamping sleeve members, respectively.
Claim 9
Dependent Claim
151 words
A tool for tightening a fastening device including an inner clamping sleeve member with an external thread and an outer clamping sleeve member with an internal thread, the outer clamping sleeve member coaxially encompassing the inner clamping sleeve member, and each clamping sleeve member including a wrench mount located at the same side of the device and including a plurality of teeth with intermediate slots, the tool comprising: an inner tubular socket spanner having a handle and an outer tubular socket spanner having a handle, which are coaxially arranged and are mutually rotatable, wherein each spanner has a plurality of teeth spaced to be insertable into said wrench mount slots, to transfer force momentum in a common plane perpendicular to a central longitudinal axis common to the sleeves of said fastening device and said spanners, and wherein mutual rotation of said spanners rotates said inner and outer clamping sleeve members, respectively.
Claim 10
Dependent Claim
165 words
A tool for tightening a fastening device including an inner clamping sleeve member with an external thread and an outer clamping sleeve member with an internal thread, the outer clamping sleeve member coaxially encompassing the inner clamping sleeve member, and each clamping sleeve member including a wrench mount located at the same side of the device and including a plurality of teeth with intermediate slots, the tool comprising: an inner tubular socket spanner and an outer tubular socket spanner, which are coaxially arranged and are mutually rotatable, wherein each of said spanners includes a wrench mount for cooperating with means for mutually moving said spanners, wherein each spanner has a plurality of teeth spaced to be insertable into said sleeve member wrench mount slots, to transfer force momentum in a common plane perpendicular to a central longitudinal axis common to the sleeves of said fastening device and said spanners, and wherein mutual rotation of said spanners rotates said inner and outer clamping sleeve members, respectively.
Claim 11
Dependent Claim
