Abstract
Abstract An articulating mechanism to provide large angular motions using a plurality of links, one of which includes a long and a short member in crossed relationship and a pair of side bars each pivotally connected to respective adjacent ends of the members. Extension bars on one side and on the other side of the long member and integral therewith function as side bars of a preceding and a succeeding link. Elimination of one type of extension bar on a link at one end of the mechanism and the other type of extension bar on a link at the other end of the mechanism provides transitional links for pivotal connection of the long cross bar of each of the transitional links to a respective rigid member.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
161 words
An articulating mechanism comprising a plurality of main link members, each having a longitudinal axis extending from one side to the other side thereof and each having a pair of pivotal axes, one on said one side and the other on said other side thereof, said pivotal axes lying in planes perpendicular to said longitudinal axis and passing through said longitudinal axis, said main link members having adjacent sides connected with the axes thereof coincident and aligned with the longitudinal axes thereof lying in a straight line, a plurality of synchronizing link members, each having a pivotal point at each end thereof, each of said synchronizing links in crossed relationship with the longitudinal axis of a respective main link member, each of said main members including an element integral therewith and pivotally connected to the adjacent end of an adjacent synchronizing link member, said element providing a pivotal point coincident with an adjacent pivotal point of said adjacent synchronizing link member.
Claim 2
Dependent Claim
161 words
An articulating mechanism comprising a plurality of main link members, each having a longitudinal axis extending from one side to the other side thereof and each having a pair of pivotal axes, one on said one side and the other on said other side thereof, said pivotal axes lying in planes perpendicular to said longitudinal axis and passing through said longitudinal axis, said main link members having adjacent sides connected with the axes thereof coincident and aligned with the longitudinal axes thereof lying in a straight line, a plurality of synchronizing link members, each having a pivotal point at each end thereof, each of said synchronizing links in crossed relationship with the longitudinal axis of a respective main link member, each of said main members including an element integral therewith and pivotally connected to the adjacent end of an adjacent synchronizing link member, said element providing a pivotal point coincident with an adjacent pivotal point of said adjacent synchronizing link member.
Claim 3
Dependent Claim
68 words
The combination of claim 1 in which each of said main members includes a pair of elements integral therewith, one element located on one side of said main member and pivotally connected to the adjacent end of an adjacent synchronizing link member, the other element located on the other side of said main link member and pivotally connected to the adjacent end of an adjacent synchronizing link member.
Claim 4
Dependent Claim
16 words
The combination of claim 1 in which the pivotal axes of a main member are parallel.
Claim 5
Dependent Claim
30 words
The combination of claim 1 in which the pivotal axis on one side of said main member is skewed with respect to the pivotal axis on the other side thereof.
Claim 6
Dependent Claim
106 words
The combination of claim 1 in which each of said main links includes a generally cylindrical member extending about the longitudinal axis thereof and having at one end thereof a pair of bearing elements defining said one pair of axes and having at the other end thereof another pair of elements defining the other of said pair of axes, and in which said element is oriented on an end of said cylindrical member such that the pivotal point thereof lies in a plane which includes the longitudinal axis of said main link member and is perpendicular to the pair of axes on the same end thereof.
Claim 7
Dependent Claim
45 words
The combination of claim 5 in which edges of each end of said cylindrical member are tapered from diametrically opposed points on an end so as to lie generally in planes making an acute angle with respect to the longitudinal axis of a main link.
Claim 8
Dependent Claim
15 words
The combination of claim 5 in which said pivotal points are provided by universal joints.
Claim 9
Dependent Claim
36 words
The combination of claim 1 in which the longitudinal axes of each of said main link members are identical and in which the length of said synchronizing link members between the pivotal points thereof are equal.
Claim 10
Dependent Claim
27 words
The combination of claim 1 in which means are provided for pivoting a main member with respect to an adjacent main member about the axis common thereto.
Claim 11
Dependent Claim
21 words
The combination of claim 1 in which flexible cylindrical bellows element surrounds said main link members and said synchronizing link members.
