Abstract
Abstract System for the simulation of human movements of a puppet as used in a programmable puppet show, which puppet is provided with mutually hingeable parts of the body, in which a number of cam disks to be driven synchronously by a motor (3) are present, each of which can be followed by a roll (4) attached to one end of a lever (6), while the other end of the lever (6) is connected to a Bowden cable (11) capable of transmitting the movement of the lever (6) to a mechanical construction which can make a part of the body perform a desired movement.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
257 words
A system for simulating human movements of a puppet having mutually hingeable limb members and which is used in a programmable puppet show comprising: a solid frame member which rotatably supports a drive shaft; a plurality of cam disks adapted to be synchronously driven by a driving motor, said cam disks being operatively associated with said drive shaft; a plurality of rolls, each of which communicates with one of said cam disks; a lever having a first end associated with one of said rolls; a spring associated with a second end of said lever, said spring being externally disposed with respect to said puppet; a Bowden cable having a first and a second end, said first end of said Bowden cable being associated with said lever; and at least one sprocket wheel, positioned inside of the puppet and associated with said limb member, said at least one sprocket wheel having a chain passed thereover, one end of said chain being associated, within the puppet, with said second end of said Bowden cable, whereby when said drive shaft is rotated by said driving motor, said roll causes said lever to bidirectonally move causing said Bowden cable to transmit the bidirectional movement of said lever, via said chain and said first sprocket wheel, to said limb member to permit said limb member to move in a predetermined manner which simulates the human movement, and whereby said spring enables said roll to remain in communication with said cam disks as said cam disk is being rotated by said drive shaft.
Claim 2
Independent Claim
257 words
A system for simulating human movements of a puppet having mutually hingeable limb members and which is used in a programmable puppet show comprising: a solid frame member which rotatably supports a drive shaft; a plurality of cam disks adapted to be synchronously driven by a driving motor, said cam disks being operatively associated with said drive shaft; a plurality of rolls, each of which communicates with one of said cam disks; a lever having a first end associated with one of said rolls; a spring associated with a second end of said lever, said spring being externally disposed with respect to said puppet; a Bowden cable having a first and a second end, said first end of said Bowden cable being associated with said lever; and at least one sprocket wheel, positioned inside of the puppet and associated with said limb member, said at least one sprocket wheel having a chain passed thereover, one end of said chain being associated, within the puppet, with said second end of said Bowden cable, whereby when said drive shaft is rotated by said driving motor, said roll causes said lever to bidirectonally move causing said Bowden cable to transmit the bidirectional movement of said lever, via said chain and said first sprocket wheel, to said limb member to permit said limb member to move in a predetermined manner which simulates the human movement, and whereby said spring enables said roll to remain in communication with said cam disks as said cam disk is being rotated by said drive shaft.
Claim 3
Dependent Claim
87 words
The system according to claim 1 further comprising a second sprocket wheel positioned inside of the puppet, each of said first and said second sprocket wheel including an axle and being arranged in a manner such that said axles are disposed in a crosswise relationship with respect to each other, thereby permitting said first and said second sprocket wheels to move independently relative to each other and whereby said chain passing over said first sprocket wheel is conducted through a recess defined in said second sprocket wheel.
Claim 4
Dependent Claim
85 words
The system according to claim 2 wherein the axle of said first sprocket wheel is rotatable vis-a-vis the axle of said second sprocket wheel and wherein a first segment of said chain passing over said first sprocket wheel is pivotably coupled by coupling means to a second segment of said chain conducted through the recess in said second sprocket wheel, said second segment being associated with said second end of said Bowden cable for allowing an independent two way bidirectional movement of said limb member.
Claim 5
Dependent Claim
19 words
A system according to claim 3 wherein said first chain segment is permanently fixed to said first sprocket wheel.
