Abstract

Abstract A molded product formed from wood flakes intermixed with a binder and a first elongated member formed from elongated wood flakes compressed and bonded together with a binder, the wood flakes having a grain direction extending generally parallel to the longitudinal axis of the flakes and the flakes being generally oriented in alignment with the longitudinal axis of the first elongated member. A second elongated member intersects the first elongated member and is integrally joined to it. The second elongated member is also formed from elongated wood flakes compressed and bonded together with a binder, the wood flakes being generally oriented in alignment with the longitudinal axis of the second elongated member. The wood flakes of the second elongated member intersect and are interleaved with the wood flakes of the first elongated member to thereby form an integral molded joint between the first elongated member and the second elongated member.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 221 words
A molded unitary product comprised of wood flakes intermixed with a binder, the product comprising a first discrete elongated member having a first longitudinal axis, said first elongated member including elongated wood flakes compressed and bonded together with a binder, said wood flakes having a grain direction extending generally parallel to the longitudinal axis thereof and said wood flakes being oriented generally in alignment with the first longitudinal axis of said first elongated member, and a second discrete elongated member having a second longitudinal axis, the longitudinal axis of said first elongated member being transverse to said second longitudinal axis, and a portion of said second elongated member intersecting a portion of said first elongated member, and said portion of said second elongated member being integrally joined to said portion of said first elongated member, said second elongated member including elongated wood flakes compressed and bonded together with a binder, said wood flakes having a grain direction extending generally parallel to said second longitudinal axis thereof and being oriented generally in alignment with said second longitudinal axis, and said wood flakes forming said portion of said second elongated member intersecting and being interleaved with said wood flakes of said portion of said first elongated member to form an integral molded joint between said first elongated member and said second elongated member.
Claim 2
Dependent Claim 221 words
A molded unitary product comprised of wood flakes intermixed with a binder, the product comprising a first discrete elongated member having a first longitudinal axis, said first elongated member including elongated wood flakes compressed and bonded together with a binder, said wood flakes having a grain direction extending generally parallel to the longitudinal axis thereof and said wood flakes being oriented generally in alignment with the first longitudinal axis of said first elongated member, and a second discrete elongated member having a second longitudinal axis, the longitudinal axis of said first elongated member being transverse to said second longitudinal axis, and a portion of said second elongated member intersecting a portion of said first elongated member, and said portion of said second elongated member being integrally joined to said portion of said first elongated member, said second elongated member including elongated wood flakes compressed and bonded together with a binder, said wood flakes having a grain direction extending generally parallel to said second longitudinal axis thereof and being oriented generally in alignment with said second longitudinal axis, and said wood flakes forming said portion of said second elongated member intersecting and being interleaved with said wood flakes of said portion of said first elongated member to form an integral molded joint between said first elongated member and said second elongated member.
Claim 3
Dependent Claim 42 words
