Abstract
Abstract Toy monster rocks have a base with a substantially flat bottom. One or more pieces are mounted for pivotal movement with respect to the base. Movement of the piece or pieces from a quiescent position to an aggressive position exposes an open mouth. An actuator effects such movement. In some embodiments the spring urges the pivotal movement against the restraint of a latch disengagable by a trigger part of the actuator. Gears are used to move pieces in other embodiments.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
110 words
A toy monster rock comprising: a hollow base piece having a substantially flat bottom; at least one other piece mounted for movement with respect to the base piece between a first position and a second position; all of the exposed surfaces of the base piece and the other piece having a simulated rocklike appearance and texture; movement of the other piece to the second position exposing a monsterlike face having an open mouth; an actuator mounted for sliding movement into and out of the substantially hollow base; the actuator including a gear rack; and gear means engaged by the rack moving the other piece between the first and second positions.
Claim 2
Dependent Claim
110 words
A toy monster rock comprising: a hollow base piece having a substantially flat bottom; at least one other piece mounted for movement with respect to the base piece between a first position and a second position; all of the exposed surfaces of the base piece and the other piece having a simulated rocklike appearance and texture; movement of the other piece to the second position exposing a monsterlike face having an open mouth; an actuator mounted for sliding movement into and out of the substantially hollow base; the actuator including a gear rack; and gear means engaged by the rack moving the other piece between the first and second positions.
Claim 3
Dependent Claim
18 words
The toy monster rock of claim 1 in which the other piece is biased toward the second position.
Claim 4
Dependent Claim
17 words
The toy monster rock of claim 1 in which the other piece is mounted for pivotal movement.
Claim 5
Dependent Claim
35 words
The toy monster rock of claim 1 in which the one other piece and a second other piece are each mounted for pivotal movement about an axis that is substantially parallel to the other axis.
Claim 6
Dependent Claim
53 words
The toy monster rock of claim 4 in which: the actuator means includes a gear rack mounted for sliding movement into and out of the base piece; and gear means engaged by the rack on the actuator effect pivotal movement of the opposed one and second other pieces toward and away each other.
Claim 7
Dependent Claim
112 words
A toy monster rock comprising: a base piece having a substantially flat bottom; at least one other piece mounted for movement with respect to the base piece between a first position and a second position; the other piece being biased toward the second position; all of the exposed surfaces of the base piece and the other piece having a simulated rocklike appearance and texture; actuator means for moving the other piece between the first and second positions; movement of the other piece to the second position exposing a monsterlike face having an open mouth; and disengagable latch means retaining the other piece in the first position in opposition to the bias means.
Claim 8
Dependent Claim
112 words
A toy monster rock comprising: a base piece having a substantially flat bottom; at least one other piece mounted for movement with respect to the base piece between a first position and a second position; the other piece being biased toward the second position; all of the exposed surfaces of the base piece and the other piece having a simulated rocklike appearance and texture; actuator means for moving the other piece between the first and second positions; movement of the other piece to the second position exposing a monsterlike face having an open mouth; and disengagable latch means retaining the other piece in the first position in opposition to the bias means.
Claim 9
Dependent Claim
20 words
The toy monster rock of claim 6 in which the actuator means includes a trigger for disengaging the latch means.
Claim 10
Dependent Claim
133 words
A toy monster rock comprising: a base piece having a substantially falt bottom; at least one other piece mounted for movement with respect to the base piece between a first position and a second position; all of the exposed surfaces of the base piece and the other piece having a simulated rocklike appearance and texture; actuator means for moving the other piece between the first and second positions; movement of the other piece to the second position exposing a monsterlike face having an open mouth; a second piece mounted for pivotal movement with respect to the open mouth; the second piece having a designated area for placement of an object of a predetermined size; and the actuator also effecting pivotal movement of the second piece to deposit the object in the open mouth.
Claim 11
Dependent Claim
133 words
A toy monster rock comprising: a base piece having a substantially falt bottom; at least one other piece mounted for movement with respect to the base piece between a first position and a second position; all of the exposed surfaces of the base piece and the other piece having a simulated rocklike appearance and texture; actuator means for moving the other piece between the first and second positions; movement of the other piece to the second position exposing a monsterlike face having an open mouth; a second piece mounted for pivotal movement with respect to the open mouth; the second piece having a designated area for placement of an object of a predetermined size; and the actuator also effecting pivotal movement of the second piece to deposit the object in the open mouth.
Claim 12
Dependent Claim
121 words
A toy monster rock comprising: a base piece having a substantially flat bottom; at least one other piece mounted for movement with respect to the base piece between a first position and a second position; all of the exposed surfaces of the base piece and the other piece having a simulated rocklike appearance and texture; actuator means for moving the other piece between the first and second positions; movement of the other piece to the second position exposing a monsterlike face having an open mouth; the one other having a portion forming one jaw of the open mouth; and a second piece mounted for pivotal movement with respect to the one other piece and having a portion forming the other jaw.
Claim 13
Dependent Claim
121 words
A toy monster rock comprising: a base piece having a substantially flat bottom; at least one other piece mounted for movement with respect to the base piece between a first position and a second position; all of the exposed surfaces of the base piece and the other piece having a simulated rocklike appearance and texture; actuator means for moving the other piece between the first and second positions; movement of the other piece to the second position exposing a monsterlike face having an open mouth; the one other having a portion forming one jaw of the open mouth; and a second piece mounted for pivotal movement with respect to the one other piece and having a portion forming the other jaw.
Claim 14
Dependent Claim
48 words
The toy monster rock of claim 9 in which: the portion of the one other piece forms the upper jaw of the mouth; and the portion of the second piece mounted for pivotal movement with respect to the one piece forms the lower jaw of the open mouth.
