Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
99 words
A toy device for picking up objects from a plane face, said device comprising a housing; a set of wheels (40) mounted for rotation to said housing blades (50) mounted for rotation to said housing to rotate with said wheels and extending partially into said housing, a magazine disposed within said housing in a position whereby rotation of said blades (50) guides the objects into said magazine, said blades consisting of a relatively stiff material, and wherein each blade comprises an integral hinge that pivots about a discrete line (60) spaced from the axis of rotation of the blade.
Claim 2
Dependent Claim
99 words
A toy device for picking up objects from a plane face, said device comprising a housing; a set of wheels (40) mounted for rotation to said housing blades (50) mounted for rotation to said housing to rotate with said wheels and extending partially into said housing, a magazine disposed within said housing in a position whereby rotation of said blades (50) guides the objects into said magazine, said blades consisting of a relatively stiff material, and wherein each blade comprises an integral hinge that pivots about a discrete line (60) spaced from the axis of rotation of the blade.
Claim 3
Dependent Claim
21 words
A toy device according to claim 1, and wherein the integral hinge (60) extends in parallel with the axis of rotation.
Claim 4
Dependent Claim
19 words
A toy device according to claim 1, and wherein each blade (50) has more than one integral hinge (60).
Claim 5
Dependent Claim
45 words
A toy device according to claim 1 wherein said integral hinge divides said blade into two plate-shaped parts and wherein a reinforcement in the form of a bead (55) is provided between the plate-shaped parts of each blade at one end of said integral hinge.
Claim 6
Dependent Claim
30 words
A toy device according to claim 1, and wherein the blades (50) have friction increasing means (90, 95) at least in the areas which are caused to contact the objects.
Claim 7
Dependent Claim
36 words
A toy device according to claim 5, and wherein the blades rotate about an axis of rotation and the friction increasing means are areas with grooves (95) extending parallel to said rotational axis of the blades.
Claim 8
Dependent Claim
27 words
A toy device according to claim 5, and wherein the blades (50) are provided with a rubber coating (90) in the areas caused to contact the objects.
Claim 9
Dependent Claim
56 words
A toy device according to claim 1, and wherein a guide plate (80) is formed adjacent the blades (50) and is constructed so that the guide plate (80) substantially follows the curvature of the blade wheel, whereby the blades can move an object (100) up the guide plate (80) from the plane face towards the magazine.
Claim 10
Dependent Claim
53 words
A device according to claim 8, and wherein the guide plate (80) is mounted to be resilient so that it may be displaced from a position of rest in a direction substantially following the movement of the blades under the action of a force increasing with the distance from the position of rest.
Claim 11
Dependent Claim
27 words
A device according to claim 1, and wherein the set of wheels (40) constitutes an integral part of the blades and defines the sides of the blades.
