Abstract
Abstract A device for storing and delivering rotational energy for rotation of a mobile is used in combination with a source of rotational energy and a control device adapted for intermittent actuation of the energy source for a predetermined period at predetermined intervals. The energy storage device has at least one multi-filament non-braided cords connected between first and second cap members. The first cap member is detachably connected to the energy source and the second cap member is detachably connected to the mobile. The cords are wound by and in response to actuation of the energy source, and urge the mobile to rotate following deactivation of the source. A method of constructing a plurality of the energy storage devices is also disclosed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
157 words
A device for storing and delivering rotational energy, for use in combination with a source of rotational energy including a motor having a shaft and adapted for actuation for a predetermined period at predetermined intervals, and an object to be rotated, the device comprising: at least one multi-filament non-braided cord, each said cord operatively connected at a first end thereof to said rotational energy source, whereby said cords are wound by and in response to actuation of said energy source; each said cord further being operatively connected at a second end thereof to said object to be rotated, whereby said object is urged to rotate following deactivation of said energy source; and first and second cap members, said first cap member being detachably connected to said shaft of said motor, said second cap member being detachably connected to said object to be rotated, said first and second cup members further having each of said cords connected therebetween.
Claim 2
Independent Claim
157 words
A device for storing and delivering rotational energy, for use in combination with a source of rotational energy including a motor having a shaft and adapted for actuation for a predetermined period at predetermined intervals, and an object to be rotated, the device comprising: at least one multi-filament non-braided cord, each said cord operatively connected at a first end thereof to said rotational energy source, whereby said cords are wound by and in response to actuation of said energy source; each said cord further being operatively connected at a second end thereof to said object to be rotated, whereby said object is urged to rotate following deactivation of said energy source; and first and second cap members, said first cap member being detachably connected to said shaft of said motor, said second cap member being detachably connected to said object to be rotated, said first and second cup members further having each of said cords connected therebetween.
Claim 3
Dependent Claim
20 words
The device as defined in claim 1, wherein said first and second cap members are of a molded plastic material.
Claim 4
Dependent Claim
16 words
The device as defined in claim 2 wherein said molded plastic material is a vinyl plastic.
Claim 5
Dependent Claim
115 words
In an apparatus for rotation of a mobile, including a source of rotational energy and a control means therefor adapted for intermittent actuation of said source for a predetermined period at predetermined intervals, the improvement comprising: means for storing and delivering rotational energy having a plurality of multi-filament non-braided cords, each said cord being constructed of a synthetic fiber and operatively connected at a first end thereof to said rotational energy source, whereby said cords are wound by and in response to actuation of said energy source, each said cord further being operatively connected at a second end thereof to said mobile, whereby said mobile is urged to rotate following deactivation of said energy source.
Claim 6
Dependent Claim
115 words
In an apparatus for rotation of a mobile, including a source of rotational energy and a control means therefor adapted for intermittent actuation of said source for a predetermined period at predetermined intervals, the improvement comprising: means for storing and delivering rotational energy having a plurality of multi-filament non-braided cords, each said cord being constructed of a synthetic fiber and operatively connected at a first end thereof to said rotational energy source, whereby said cords are wound by and in response to actuation of said energy source, each said cord further being operatively connected at a second end thereof to said mobile, whereby said mobile is urged to rotate following deactivation of said energy source.
Claim 7
Dependent Claim
15 words

Claim 8
Dependent Claim
19 words
The apparatus as defined in claim 4 wherein said source of rotational energy is a motor having a shaft.
Claim 9
Dependent Claim
166 words
In an apparatus for rotation of a mobile, including a source of rotational energy and a control means therefor adapted for intermittent actuation of said source for a predetermined period at predetermined intervals, said source including a motor having a shaft, the improvement comprising: means for storing and delivering rotational energy having at least one multi-filament non-braided cord, each said cord operatively connected at a first end thereof to said rotational energy source, whereby said cords are wound by and in response to actuation of said energy source, each said cord further being operatively connected at a second end thereof to said mobile, whereby said mobile is urged to rotate following deactivation of said source, said energy storage and delivery means further including first and second cap members, said first cap member being detachably connected to said shaft of said motor, said second cap member being detachably connected to said mobile, said first and said second cap members further having each of said cords connected therebetween.
Claim 10
Dependent Claim
