Abstract
Abstract A stackable toy comprising a doll having a centrally disposed, vertically movable pin, said pin being recessed within the doll when in retracted position and extending upwardly from the doll when in projected position, a socket being formed within the doll below the pin. The projected pin of one such doll is adapted to engage the socket of a second such doll to assemble the two dolls in stacked positions. Each doll is also provided with angularly disposed pin-shaped limbs, e.g. arms, and these limbs are equally engageable with a doll socket. A plurality of dolls made in accordance with this invention may be stacked by means of their respective centrally disposed pins as well as by means of their respective pin-shaped limbs. Various alternative means are provided for extending and retracting the centrally disposed pin. In its simplest form the pin is manually movable into either projected or retracted position. Other alternatives involve the use of helical cams or guide formations on the pin or in the body of the toy or both.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
205 words
A stackable toy, comprising: (a) a doll, (b) a pin mounted in said doll for longitudinal movement relative to the doll, (c) said pin being movable in one direction to outwardly projecting positiion and in the opposite direction to inwardly retracted position, (d) a socket formed in said doll in registration with said pin, (e) said socket being engageable with the pin of a second such doll when said pin is in outwardly projecting position, (f) the pin of the first doll, when in outwardly projecting position, being engageable with the socket of a third such doll, (g) whereby the first doll is stackable with the second and third such dolls, (h) said doll comprising a body, a head and a base, (i) said body and head having a continuous passage formed therein along the longitudinal axis of the doll and said passage being open at the top of said head, (j) said pin being mounted within said passage and being longitudinally movable therein between retracted and outwardly projecting positions relative to the doll, (k) means for moving the pin into retracted and projecting positions, (l) said projecting and retracting means comprising a helical cam and cam follower means between the doll and the pin.
Claim 2
Dependent Claim
205 words
A stackable toy, comprising: (a) a doll, (b) a pin mounted in said doll for longitudinal movement relative to the doll, (c) said pin being movable in one direction to outwardly projecting positiion and in the opposite direction to inwardly retracted position, (d) a socket formed in said doll in registration with said pin, (e) said socket being engageable with the pin of a second such doll when said pin is in outwardly projecting position, (f) the pin of the first doll, when in outwardly projecting position, being engageable with the socket of a third such doll, (g) whereby the first doll is stackable with the second and third such dolls, (h) said doll comprising a body, a head and a base, (i) said body and head having a continuous passage formed therein along the longitudinal axis of the doll and said passage being open at the top of said head, (j) said pin being mounted within said passage and being longitudinally movable therein between retracted and outwardly projecting positions relative to the doll, (k) means for moving the pin into retracted and projecting positions, (l) said projecting and retracting means comprising a helical cam and cam follower means between the doll and the pin.
Claim 3
Dependent Claim
117 words
A stackable toy in accordance with claim 1, wherein: (a) the doll head is rotatable relative to the doll body about the longitudinal axis of the doll, (b) the pin being keyed to the head for rotational movement therewith while being free to move longitudinally through the passage, (c) the helical cam being formed on the doll body, (d) the cam follower means being formed on the pin and being engageable with the helical cam on the doll body, (e) whereby rotating the head relative to the body in one direction causes the pin to project outwardly from said passage, and (f) rotating the head in the opposite direction causes the pin to retract in said passage.
Claim 4
Dependent Claim
42 words
A stackable toy in acordance with claim 2, wherein: (a) non-helical extensions are provided on opposite ends of the helical cam, (b) said cam follower means being engageable with the non-helical extensions to support the pin in its projected and retracted positions.
Claim 5
Dependent Claim
125 words
A stackable toy in accordance with claim 1, wherein: (a) the doll head is rotable relative to the doll body about the longitudinal axis of the doll, (b) the pin being keyed to the doll body to prevent rotational movement of the pin relative to the body while permitting longitudinal movement of said pin through the passage, (c) the helical cam being formed on the pin, (d) the cam follower means being formed on the doll head and being engageable with the helical cam on the pin, (e) whereby rotating the head relative to the body in one direction causes the pin to project outwardly from said passage, and (f) rotating the head in the opposite direction causes the pin to retract in said passage.
Claim 6
Dependent Claim
42 words
A stackable toy in accordance with claim 4, wherein: (a) non-helical extensions are provided on opposite ends of the helical cam, (b) said cam follower means being engageable with the non-helical extensions to support the pin in its projected and retracted positions.
Claim 7
Dependent Claim
136 words
A stackable toy in accordance with claim 1, wherein: (a) the doll base is rotatable relative to the doll body and head about the longitudinal axis of the doll, (b) the pin being keyed to the doll body or head to prevent rotational movement of the pin relative to the doll body and head while permitting longitudinal movement of said pin through the passage, (c) the helical cam being formed on the doll body, (d) the cam follower means being formed on the pin and being engageable with the helical cam on the doll body, (e) whereby rotating the base relative to the doll body and head in one direction causes the pin to project outwardly from said passage, and (f) rotating the base in the opposite direction causes the pin to retract in said passage.
Claim 8
Dependent Claim
42 words
A stackable toy in accordnce with claim 6, wherein: (a) non-helical extensions are provided on opposite ends of the helical cam, (b) said cam follower means being engageable with the non-helical extensions to support the pin in its projected and retracted positions.
