Description

The invention relates to the woodworking industry and can be used in the manufacture of frame-panel door panels.

A door leaf coated with a finishing film is known, in which longitudinal grooves are made at the ends to accommodate film joints on all end surfaces of the door leaf. At the same time, an insert made of solid material is installed in the grooves motionlessly, flush with the end surface, the profile of which corresponds to the groove profile [1].

This solution increases the service life due to the absence of seams at the ends of the door leaf and eliminates the risk of peeling off the facing film at the edge of the door leaf. However, when using thin and / or glossy cladding films or paints with a low dry residue at the ends of door leaves, an adhesive joint can be visually visible between the sheets of the cladding and the frame through the cladding, and there is also a risk of a difference in the flatness of the edge of the sheet due to shrinkage or swelling of wood or wood material in the frame of the door leaf, while the facing film is deformed.

A door leaf is known comprising a trim, honeycomb core and sheets of facing material, characterized in that an veneer is additionally installed on the side ends of the door leaf, while the veneer closes the ends of the sheets of door leaf cladding material [2].

The advantages of this door leaf design are an increase in the wear resistance and edge strength of the door leaf, however, this design is not suitable for coating with a thin finishing film or paint materials with a low dry residue. The wood veneer has an anisotropic structure, and when the door leaf edge is coated with thin and / or glossy cladding films or low-solids paintwork materials, the wood structure appears. Also, veneer wood is subject to shrinkage and swelling, which may cause deformation of the facing film at the ends of the door leaf.

This door leaf structure is taken as a prototype.

The technical result, which this solution is aimed at, is to reduce the deformation of the facing film at the ends when using thin and / or glossy facing films and paints with a low dry residue.

This is achieved by the fact that an edge, for example, made of plastic, is fastened to the door leaf before lining with film or finishing with paints and varnishes, which hides the adhesive joint between the facing sheet material and the frame of the door leaf made, for example, of wood. It is advisable to fasten the edge to the entire width of the end (s). As a result, the lining film or paint material lies on the attached edge, which hides the heterogeneity of gluing the frame with the sheets of the facing plate material, allowing the use of thin films or paints with a low dry residue. Reduces the likelihood of deformation of the facing film at the ends of the canvas due to changes in the geometry of the frame of the canvas with an increase or decrease in its moisture content.

The cross section of the claimed design of the door leaf is illustrated in figures 1-4. The door leaf is lined with artificial film and / or finished with paints and varnishes 1, before facing (trim), an edge 2 is attached to the end of the door leaf, which covers the ends of the sheets of plate material 3 and the frame of the door leaf 4. This ensures uniformity of the ends of the door, thereby increasing wear resistance and eliminates the possibility of a difference in flatness at the ends of the door leaf during operation due to shrinkage or swelling of the frame, leading to deformation of the facing film. The manifestations of adhesive joints disappear when using thin and / or glossy cladding films or paints with a low dry residue.

Alternatively, the attached edge in cross section may take the form of a trapezoid (Fig. 2), a segment of a circle (Fig. 3), or if the door leaf is made with a double vestibule or overlay (Fig. 4), the edge is installed on all ends of the door leaf.

The attached edge can be made of plastic, for example, polyvinyl chloride, polypropylene, polyethylene, etc., as well as of wood-based materials such as MDF, HDF, etc., particleboard, plywood, etc.

The thickness of the attached edge depends on the material, operating conditions and the method of its fastening, while the thickness of the edge may vary depending on the required performance and the geometric dimensions of the door leaf.

For vertical and horizontal ends of the door leaf, the material and geometric parameters of the edge of the door attached to it can vary depending on the required characteristics of the door leaf.

Fastening the edges to the door leaf can be carried out using adhesive material (glue) and / or fasteners (nails, staples, studs, etc.).

This design of the door leaf solves the problem of facing the ends of door leafs with glossy or thin films with cladding films, or when finishing with paints and varnishes with a low dry residue, because the gluing of the frame and the sheets of the facing material, for example MDF, is not visually visible. Our design also solves the problem when, during operation, deviations from flatness appear on the edges of door leaves due to drying or swelling of the wood or wood material in the door leaf frame, leading to deformation of the facing film.
