Abstract
Abstract A grab for a toy crane is provided with two two-armed levers having a common axis of rotation. Portions of the levers overlap each other at the axis of rotation about which the levers are mutually hinged at at least two places. Each lever has a first arm and a second arm which are mutually contiguous solely on one side of a central plane of the grab perpendicular to the axis of rotation.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
124 words
A grab for a toy crane, comprising two, two-armed levers, said levers having a common axis of rotation and arranged to overlap so as to engage in a releasable, rotatable snap-fit connection with each other at the axis of rotation, said arms being mutually hinged at at least two points along the axis of rotation, wherein each lever comprises a first arm and a second arm each said lever comprising engagement means to engage suspension means from a toy crane, said arms of each lever being contiguous essentially on one side of a central plane of the grab which is perpendicular to said axis whereby the grab is adapted to grip an object by mutual movement of the levers about the axis of rotation.
Claim 2
Dependent Claim
124 words
A grab for a toy crane, comprising two, two-armed levers, said levers having a common axis of rotation and arranged to overlap so as to engage in a releasable, rotatable snap-fit connection with each other at the axis of rotation, said arms being mutually hinged at at least two points along the axis of rotation, wherein each lever comprises a first arm and a second arm each said lever comprising engagement means to engage suspension means from a toy crane, said arms of each lever being contiguous essentially on one side of a central plane of the grab which is perpendicular to said axis whereby the grab is adapted to grip an object by mutual movement of the levers about the axis of rotation.
