Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
92 words
A rake or similar hand implement for working the ground or for moving plants, grass, or the like, comprising a crosshead of synthetic plastics material which carries a handle socket and at which metal tines are secured at an angle thereto, said tines having anchoring means at their ends opposite to their free ends, flexure-resistant reinforcing means bearing against said anchoring means and extending in logitudinal direction of the crosshead, said anchoring means and reinforcing means being embedded in the synthetic plastics material of the crosshead and enclosed thereby on all sides.
Claim 2
Dependent Claim
92 words
A rake or similar hand implement for working the ground or for moving plants, grass, or the like, comprising a crosshead of synthetic plastics material which carries a handle socket and at which metal tines are secured at an angle thereto, said tines having anchoring means at their ends opposite to their free ends, flexure-resistant reinforcing means bearing against said anchoring means and extending in logitudinal direction of the crosshead, said anchoring means and reinforcing means being embedded in the synthetic plastics material of the crosshead and enclosed thereby on all sides.
