Wood treatment device for the pressure-free treatment of wood and a pressure-free method for treating wood

A method for treating wood, the method comprising:

• a) providing a wood treatment device for a long-term treatment of wood, the wood treatment device comprising:
• a cylindrical hollow body comprising an inner end and an outer end facing away from the inner end, wherein the inner end, when the wood treatment device is in use, is positioned inside the wood;
• the cylindrical hollow body further comprising an open end face at the inner end, wherein the open end face forms a first outlet opening configured to be positioned in or near regions of the wood that are to be treated;
• the cylindrical hollow body further comprising a wall surface and a second outlet opening arranged at the wall surface and configured to be positioned in or near regions of the wood that are to be treated;
• the cylindrical hollow body further comprising a receiving space delimited in a radial outward direction by the wall surface and configured to receive a carrier material provided with an active agent for wood treatment;
• a thrust pin arranged inside the cylindrical hollow body and comprising a central cylinder, the central cylinder extending along a longitudinal axis of the cylindrical hollow body and comprising a first end arranged at the inner end and a second end arranged at the outer end, wherein the thrust pin is configured to be displaced inside the cylindrical hollow body and is configured to be acted on at the outer end of the cylindrical hollow body from outside of the cylindrical hollow body;
• the thrust pin comprising a first closure section connected to the first end of the central cylinder and a second closure section connected to the central cylinder at a spacing from the first end and extending radially outwardly from the central cylinder toward the wall surface of the cylindrical hollow body, wherein the first closure section closes off the first outlet opening and the second closure section closes off the second outlet opening in a state of non-use of the wood treatment device and wherein, in a state of use of the wood treatment device, the thrust pin, when displaced, releases the first outlet opening and the second outlet opening and brings the receiving space into contact with the wood;
• b) applying an active agent for wood treatment to a carrier material and introducing the carrier material provided with the active agent for wood treatment into the receiving space of the wood treatment device;
• c) driving the wood treatment device into the wood;
• d) displacing the thrust pin of the wood treatment device to release the first outlet opening and the second outlet opening to bring into contact the receiving space with the wood and to release the active agent for wood treatment into the wood;
• e) leaving behind the wood treatment device in the wood.
