Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
122 words
A force applying mechanism moulded in one piece of plastics material and comprising: first and second jaw portions, a pair of elongate, first chords joined to said first jaw portion and diverging outwardly therefrom, and a pair of elongate, second chords having first end portions joined to respective first chords and second end portions joined to said second jaw portion, the second chords having flexible, convex portions which are brought progressively into supporting engagement with each other and flattened on pivotal movement of the first chords towards each other to close the jaw portions relatively together during application of a force, and said first jaw portion providing a track guiding said second jaw portion during closure of the jaw portions relatively together.
Claim 2
Dependent Claim
122 words
A force applying mechanism moulded in one piece of plastics material and comprising: first and second jaw portions, a pair of elongate, first chords joined to said first jaw portion and diverging outwardly therefrom, and a pair of elongate, second chords having first end portions joined to respective first chords and second end portions joined to said second jaw portion, the second chords having flexible, convex portions which are brought progressively into supporting engagement with each other and flattened on pivotal movement of the first chords towards each other to close the jaw portions relatively together during application of a force, and said first jaw portion providing a track guiding said second jaw portion during closure of the jaw portions relatively together.
Claim 3
Dependent Claim
43 words
The structure as recited in claim 1, and further including: a rail secured to said second jaw portion and interposed between said second chords and progressively supporting said flexible portions of said second chords pivotal movement of said first chords toward each other.
Claim 4
Dependent Claim
30 words
The structure as recited in claim 2, wherein, said first jaw portion provides a passageway receiving said second jaw portion, said track being provided by opposite walls of the passageway.
Claim 5
Dependent Claim
19 words
The structure as recited in claim 1 or claim 2 or claim 3, wherein, said first chords are flexible.
Claim 6
Dependent Claim
31 words
The structure as recited in claim 1 or claim 2 or claim 3, wherein, said first chords provide handles by which said mechanism is actuated to displace said moveable jaw portion.
Claim 7
Dependent Claim
113 words
A unitary force applying mechanism, comprising: a fixed jaw portion, a moveable jaw portion constructed for displacement toward and away from said fixed jaw portion, a pair of elongated, first chords joined to said fixed jaw portion and diverging outwardly therefrom, and a pair of elongated, second chords having first end portions joined to respective first chords and converging toward each other with second end portions thereof joined to said moveable jaw portion, said second chords being supported against each other progressively along their lengths upon pivoting said first chords toward each other to displace said moveable jaw portion, and said fixed jaw portion includes a track reciprocatingly receiving said moveable jaw portion.
Claim 8
Dependent Claim
113 words
A unitary force applying mechanism, comprising: a fixed jaw portion, a moveable jaw portion constructed for displacement toward and away from said fixed jaw portion, a pair of elongated, first chords joined to said fixed jaw portion and diverging outwardly therefrom, and a pair of elongated, second chords having first end portions joined to respective first chords and converging toward each other with second end portions thereof joined to said moveable jaw portion, said second chords being supported against each other progressively along their lengths upon pivoting said first chords toward each other to displace said moveable jaw portion, and said fixed jaw portion includes a track reciprocatingly receiving said moveable jaw portion.
Claim 9
Dependent Claim
115 words
A force applying mechanism comprising: first and second jaw portions, a pair of elongate, first chords integrally joined to said first jaw portion and diverging outwardly therefrom, and a pair of elongate, second chords having first end portions integrally joined to respective first chords and second end portions joined to said second jaw portion, the second chords having flexible, convex portions which are brought progressively into supporting engagement with each other and flattened on pivotal movement of the first chords towards each other to close the jaw portions relatively together during application of a force, said first jaw portion providing a track guiding said second jaw portion during closure of the jaw portions relatively together.
Claim 10
Dependent Claim
115 words
A force applying mechanism comprising: first and second jaw portions, a pair of elongate, first chords integrally joined to said first jaw portion and diverging outwardly therefrom, and a pair of elongate, second chords having first end portions integrally joined to respective first chords and second end portions joined to said second jaw portion, the second chords having flexible, convex portions which are brought progressively into supporting engagement with each other and flattened on pivotal movement of the first chords towards each other to close the jaw portions relatively together during application of a force, said first jaw portion providing a track guiding said second jaw portion during closure of the jaw portions relatively together.
