Component Made from a Material Consisting Predominantly of Renewable Raw Materials, with at Least One Densified Region, and Method and Tool for Producing the Densified Region
Simple SummaryContent extracted from patent full text and abstract with AI.
This patent describes a component made primarily from renewable raw materials, such as wood or similar substances, that includes at least one hole where the surrounding material has been locally compacted. This is achieved by a process in which a mandrel with a tapered tip is inserted into the material, creating a hole and densifying the area around it. The patent also includes the method and the specific tool used for this process.
Use CasesContent extracted from patent full text and abstract with AI.
- Production of wooden or bio-composite structural parts with enhanced strength around apertures
- Manufacture of furniture, doors, or panels where screws or fastener holes require reinforcement
- Eco-friendly building components needing increased durability at connection points
- Manufacturing automotive or transport components from renewable materials with improved fastener retention
BenefitsContent extracted from patent full text and abstract with AI.
- Improved durability and strength of renewable-material components at critical points (such as around holes)
- Reduces reliance on synthetic or non-renewable reinforcement inserts
- Provides an environmentally friendly solution for enhancing structural performance
- Maintains the use of majority renewable materials, supporting sustainability goals
- Allows for more reliable joining or mounting in components made from renewable resources

Patent Abstract
Die Erfindung betrifft ein Bauteil aus einem Werkstoff, der überwiegend aus nachwachsenden Rohstoffen besteht, wobei das Bauteil wenigstens ein Loch mit einer Längsachse (A) aufweist und der Werkstoff in dem, sich an das Loch umfangsseitig anschließenden Bereich, lokal verdichtet ist. Verfahrensgemäß dringt mindestens ein Dorn, der einen im wesentlichen zylindrischen Schaft und eine Spitze mit einem sich in Richtung zum Bauteil reduzierenden Durchmesser aufweist, in den Werkstoff ein, erzeugt dabei ein Loch im Bauteil und verdrängt den Holzwerkstoff radial und/oder axial, wodurch der Werkstoff in dem, das Loch umgebenden Bereich verdichtet wird. Das zur Durchführung des Verfahrens verwendete Werkzeug ist in Form wenigstens eines Dorns mit einem zylindrischen oder polygonförmigen Schaft und einer sich in Richtung zum Bauteil im Durchmesser reduzierenden Spitze ausgebildet.
