The HDF boards of the surface layers and of the at least some of the distance elements comprise wood particles bonded by a resin including an isocyanate, such as methylene diphenyl di-isocyanate, MDI.

A blow-molded plastic frame of a portable collapsible sign includes a first outer portion, a second outer portion spaced apart from the first outer portion, and a pattern of structural stiffening features formed in the first and second outer portions. The pattern comprises rows and columns of first depressions extending from the first outer portion into a hollow interior portion between the first and second outer portions, and rows and columns of second depressions extending from the second outer portion into the hollow interior portion. Each first depression has a first floor comprising three first arms having rotational symmetry. Each first arm is rotated from another first arm by 120 degrees. Each second depression has a second floor comprising three second arms having rotational symmetry. Each second arm is rotated from another second arm by 120 degrees. The first floor of each first depression is aligned with the second floor of an adjacent second depression.

A box is made of structural boards having a face plate (2) including a main body portion (2c) that is substantially in one plane and a peripheral portion (2a) surrounding the main body. The boards further include a base plate (3) having integrally formed protrusions. The lower surface of the face plate (2) is attached to and supported on top of the protrusions. A stiffener (4) connects the peripheral portion (2a) of the face plate (2) and the base plate (3) together. At least a part of the stiffener (4) is fixedly connected to the base plate (3), and at least another part of the stiffener (4) is fixedly connected to at least a part of a lower surface of the peripheral portion (2a) of the face plate.

A structural board comprises a surface board and a bottom board. The bottom board comprises a first supporting surface and a second supporting surface, and the surface board is fixedly connected on the second supporting surface. The bottom board comprises a plurality of protruding cavities spaced apart from one another. Two end surfaces of each of the plurality of protruding cavities along a protruding direction of the plurality of protruding cavities respectively defines the first supporting surface and the second supporting surface. Each of a plurality of straight ribs is defined by two adjacent, spaced apart protruding cavities of the plurality of protruding cavities. Some of the plurality of straight ribs are connected together in an extending direction, and the plurality of straight ribs with different extending directions extend to be cross-connected to one another to form a polygonal mesh structure that defines the first supporting surface.

A blow-molded unitary structure includes a panel having first and second panel walls and a generally hollow interior between the first and second panel walls. The structure also includes a plurality of depressions, or at least one ridge, or both the depressions and ridge to enhance the strength of the structure. The plurality of depressions is monolithically formed with the panel, recessing from the second panel wall toward the first panel wall. A depression has a side wall composed of first and second segments. Cross-sectional-wise, the first and second segments have different widths and thus collectively forms a step between the first and second segments. A ridge is also monolithically formed with the panel and includes a section, at which the width of the ridge varies along the height direction of the ridge.

An item of furniture includes at least one furniture element and at least one fitting for guiding a movable furniture part. The fitting is integrated into a plate-shaped composite element that is mounted parallel to a wall of the at least one furniture element and is mounted inside the furniture element.

A method for manufacturing furniture using extruded polymeric honeycomb profiles, capable of providing the market with a sustainable product which can be exposed to moisture. The method includes three polymeric extruded honeycomb profiles, the extruded profile being fitted to the profile by inserting the flanges into the angled conformation, being anchored by the contact of the external flexible flaps with the flexible flaps. The union of profiles and provides an intermediate fitting allowing fixating the shelves, for example, being anchored by inserting the appendage into the angled conformations, fixating them through contact of the flexible external flanges with the external flexible flaps, allowing the formation of a three-part conjugation, being one profile and two profiles. The method allows the union of two profiles through the union of the external flexible flaps of the appendage, anchored to the internal flexible flaps of the flanges. After fitting the three profiles, which can be bottom, bases and shelves, the furniture is semi finished, the sides are mounted using profiles also fitted to the bottom, which refer to and position them, allowing the use of self-tapping screws attached to the hole of the support, allowing it to be anchored internally to the profiles, thus improving the finish in view of its honeycomb structure, after being finished with the cap to conceal the hole and the screw. The cutting edges are covered with adhesive border strips along the side walls, internal structural elements and supports.

A modular construction panel includes a backing veneer layer, a lattice structure having a plurality of wood strips on a surface of the veneer layer, and a composite material serving as filler material between the wood strips of the lattice structure. The lattice structure includes a plurality of longitudinal wood strips positioned at right angles relative to a plurality of transverse wood strips. The modular construction panel may further include female joiner locks embedded in the filler material. A facing material may be attached to the modular construction panel by coupling to the female joiner locks.

A device for reinforcing and ventilating furniture, includes at least one first longitudinal profile that has at least one line of through holes arranged along the longitudinal dimension thereof, and at least one second longitudinal profile, the at least first profile and the at least second profile being mutually joined along the same longitudinal dimension thereof.

A panel assembly for providing an apron-front aesthetic for a sink installed in a cabinet. The panel assembly includes a mounting body configured for coupling to a cabinet and a cover panel coupled to the mounting body to provide an apron-front aesthetic for a sink coupled to the cabinet. The mounting body may include an opening and the cover panel may be located within the opening. The mounting body may be configured to couple to a portion of the cabinet where a false drawer would normally be located. The panel assembly may include a fastener configured to extend through a portion of the mounting body to engage the cover panel so as to secure the cover panel in place with respect to the mounting body. The cover panel may be generally planar and have a metallic finish or a textured surface finish.
