Abstract
Abstract A mechanism including a support and two elements carried by the support for engaging the legs of a doll. The support carries a pivotable arm, and slots in the support and arm cross each other. A pin connected to each element passes through both slots, and the arm oscillates with respect to the support by engaging stationary abutments along the path of travel of the support. An upwardly concave guide surface on the support causes the elements to move along an arcuate path.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
115 words
A walking mechanism for a doll, comprising a. a support, b. a pair of elements for engaging the legs of a doll, said elements being carried by said support and movable with respect thereto, said elements being movable along substantially parallel paths, c. means carried by said support for moving each of said elements in two opposite directions with respect to said support, and for moving each of said elements in a direction opposite to the direction of movement of the other, and d. at least one upwardly concave guide surface for each of said elements for causing the latter to move along an arcuate path having a center of curvature located above said support.
Claim 2
Dependent Claim
115 words
A walking mechanism for a doll, comprising a. a support, b. a pair of elements for engaging the legs of a doll, said elements being carried by said support and movable with respect thereto, said elements being movable along substantially parallel paths, c. means carried by said support for moving each of said elements in two opposite directions with respect to said support, and for moving each of said elements in a direction opposite to the direction of movement of the other, and d. at least one upwardly concave guide surface for each of said elements for causing the latter to move along an arcuate path having a center of curvature located above said support.
Claim 3
Dependent Claim
34 words
A walking mechanism as defined in claim 1 including means for moving said support along a predetermined path, and stationary means along said path for cooperating with said means (c) to move said elements.
Claim 4
Dependent Claim
69 words
A walking mechanism as defined in claim 2 wherein said stationary means include abutments spaced apart along the length of said path, each two successive abutments being on opposite sides of path, and said means (c) includes a pivotable arm, said elements moving in response to pivotal movement of said arm, And said arm being oscillated by successive engagements with said abutments as said support moves along said path.
Claim 5
Dependent Claim
93 words
A walking mechanism as defined in claim 2 wherein said support is rotatable with respect to said means for moving said support along a predetermined path, and including a follower depending from said toy support, said follower being non-rotatably connected to said toy support, and a stationary guide means along the path of travel of said toy support as said stage means rotates, said guide means slidably and non-rotatably accommodating said follower to prevent rotation of said toy support as a result of the engagement between said animating means and said stationary means.
Claim 6
Dependent Claim
85 words
A walking mechanism as defined in claim 1 wherein said support includes at least one slot, said means (c) includes an arm pivoted to said support at a point spaced from said slot, said arm having a slot crossing the slot in said support, and a pin connected to each of said elements, said pin projecting through said slots and being slidable therein, swinging movement of said arm causing said pin to move along the lengths of both slots to thereby move its respective element.
Claim 7
Dependent Claim
57 words
A walking mechanism as defined in claim 5 including means for moving said support along a predetermined path, stationary abutments spaced apart along the length of said path, each two successive abutments being on opposite sides of said path, and said arm being oscillated by successive engagements with said abutments as said support moves along said path.
Claim 8
Dependent Claim
68 words
A walking mechanism as defined in claim 1 wherein said support includes upwardly and downwardly projecting ridges, the upper edge of said upwardly projecting ridge and the lower edge of said downwardly projecting ridge being spaced apart and each said edge defining one of said upwardly concave guide surfaces, and a member carrying each of said elements, said members being slidable between said upper and lower ridge edges.
Claim 9
Dependent Claim
15 words
A walking mechanism as defined in claim 7 wherein said ridges are spaced apart laterally.
Claim 10
Dependent Claim
69 words
A walking mechanism as defined in claim 7 including a first opening along one side of said downwardly projecting ridge, a second opening along the opposite side of said upwardly projecting ridge, one of said elements projecting through said first opening, a pin carried by said member projecting through said second opening, and means engaging said pin for sliding said member and hence said element along said ridge edges.
Claim 11
Dependent Claim
116 words
A walking mechanism for a doll, comprising a. a support, b. a pair of elements for engaging the legs of a doll, said elements being carried by said support and movable with respect thereto, said elements being movable along substantially parallel paths, c. means for moving said support along a predetermined path, d. abutments spaced apart along the length of said path, each two successive abutments being on opposite sides of said path, and e. an arm pivoted to said support and adapted to engage said abutments, said elements moving in response to pivotal movement of said arm, and said arm being oscillated by successive engagements with said abutments as said support moves along said path.
Claim 12
Dependent Claim
116 words
A walking mechanism for a doll, comprising a. a support, b. a pair of elements for engaging the legs of a doll, said elements being carried by said support and movable with respect thereto, said elements being movable along substantially parallel paths, c. means for moving said support along a predetermined path, d. abutments spaced apart along the length of said path, each two successive abutments being on opposite sides of said path, and e. an arm pivoted to said support and adapted to engage said abutments, said elements moving in response to pivotal movement of said arm, and said arm being oscillated by successive engagements with said abutments as said support moves along said path.
Claim 13
Dependent Claim
82 words
A walking mechanisem as defined in claim 10 wherein said support includes at least one slot, said arm being pivoted to said support at a point spaced from said slot, said arm having a slot crossing the slot in said support, and a pin connected to each of said elements, said pin projecting through said slots and being slidable therein, swinging movement of said arm causing said pin to move along the lengths of both slots to thereby move its respective element.
