Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
133 words
Apparatus which is convertible between a curved shape suitable for wearing around the wrist as a wristwatch and an elongated form suitable for use as a hand-held radiotelephone with a microphone and a speaker adjacent respective opposite ends of said elongated form comprising: a plurality of substantially rigid link members disposed side by side in a series, adjacent link members in said series being pivotally connected to one another, the pivotal axis of each pivotal connection being substantially parallel to the longitudinal axis of a user's wrist when the apparatus is worn on the wrist; and means for pivoting the link members connected by each pivotal connection between relative positions in which said link members collectively form said curved shape and relative positions in which said link members collectively form said elongated form.
Claim 2
Dependent Claim
133 words
Apparatus which is convertible between a curved shape suitable for wearing around the wrist as a wristwatch and an elongated form suitable for use as a hand-held radiotelephone with a microphone and a speaker adjacent respective opposite ends of said elongated form comprising: a plurality of substantially rigid link members disposed side by side in a series, adjacent link members in said series being pivotally connected to one another, the pivotal axis of each pivotal connection being substantially parallel to the longitudinal axis of a user's wrist when the apparatus is worn on the wrist; and means for pivoting the link members connected by each pivotal connection between relative positions in which said link members collectively form said curved shape and relative positions in which said link members collectively form said elongated form.
Claim 3
Independent Claim
58 words
The apparatus defined claims 1 further comprising: means associated with each of said pivotal connections for limiting the pivoting of the link members connected by said pivotal connection so that pivoting of said link members toward the relative positions associated with said elongated form stops when said link members reach the relative positions associated with said elongated form.
Claim 4
Dependent Claim
42 words
The apparatus defined claim 2 wherein said means for limiting comprises: stop surfaces on each of said link members, said stop surfaces on adjacent link members abutting one another when said link members reach the relative positions associated with said elongated form.
Claim 5
Dependent Claim
60 words
The apparatus defined in claim 1 further comprising: means associated with each of said pivotal connections for limiting the pivoting of the link members connected by said pivotal connections so that pivoting of said link members toward the relative positions associated with said curved shape stops when said link members reach the relative positions associated with a predetermined curved shape.
Claim 6
Dependent Claim
44 words
The apparatus defined in claim 4 wherein said means for limiting comprises: stop surfaces on each of said link members, said stop surfaces on adjacent link members abutting one another when said link members reach the relative positions associated with said predetermined curved shape.
Claim 7
Dependent Claim
102 words
The apparatus defined in claim 1 wherein said means for pivoting the link members comprises: a first flexible member extending along at least a subplurality of adjacent link members in said series, said first flexible member being laterally spaced to a first side from the pivotal axes of the pivotal connections between the adjacent link members in said subplurality, and said first flexible member being anchored at points adjacent the link members at respective opposite ends of said subplurality; and means for changing the effective length of said first flexible member between the points at which said first flexible member is anchored.
Claim 8
Dependent Claim
35 words
The apparatus defined in claim 6 further comprising: means for maintaining said first flexible member adjacent said subplurality of link members regardless of whether said apparatus is in said curved shape or said elongated form.
Claim 9
Dependent Claim
26 words
The apparatus defined in claim 7 wherein said means for maintaining comprises: a flexible sheath surrounding said subplurality of link members and said first flexible member.
Claim 10
Dependent Claim
106 words
The apparatus defined in claim 6 wherein said means for pivoting the link members further comprises: a second flexible member, which is also longitudinally resilient, extending along said subplurality of adjacent link members, said second flexible member being laterally spaced to a second side from the pivotal axes of the pivotal connections between the adjacent link members in said subplurality, and said second flexible member being anchored adjacent the points at which said first flexible member is anchored, said second flexible member being prestressed in tension so that it keeps said first flexible member in tension regardless of the effective length of said first flexible member.
Claim 11
Dependent Claim
48 words
The apparatus defined in claim 6 wherein said means for changing the effective length of said first flexible member comprises: a rotatable shaft around which some of said first flexible member can be wound when it is desired to reduce the effective length of said first flexible member.
Claim 12
Dependent Claim
31 words
The apparatus defined in claim 1 further comprising: a main body member intermediate said series of link members; and first and second end members adjacent respective opposite ends of said series.
Claim 13
Dependent Claim
26 words
The apparatus defined in claim 11 wherein said microphone is disposed in said first end member and said speaker is disposed in said second end member.
Claim 14
Dependent Claim
24 words
The apparatus defined in claim 12 further comprising: display means, a telephone dialing keypad, and control buttons, all disposed in said main body member.
