Description

The subject of the invention is a decorative and/or structural frame constituting a fastening element for pictures made by any technique and on any substrate, mirrors, as well as monitor screens or any type of displays, as well as for placing various decorative and ornamental objects, vases, flowers, etc. therein.
The picture or pictures frame known from EP3056119 patent description is a folded sheet of cardboard or any other suitable material and comprises a central rectangular or square picture receiving part and comprises leaf parts formed on the sides of the central rectangular part and each of the leaf parts comprises four parallel lines, cuts to form four folding strands parallel to the sides. The four leaf parts are folded backwards along the fold line into a folded position resting on the four side margins of the central rectangular picture part on its rear face, thus forming four tubular frame parts of rectangular cross section. The pair of second, externally opposing leaf strands have extensions which are placed inside the second pair of opposing leaves after they are folded, thus joining the leaves together when folded to form a frame. The pairs of third strands of leaves have alternately pairs of leaves and slots arranged so that after folding the leaves, the respective leaves move into appropriate slots, thus securing the frame elements against disassembly and falling together.
The disadvantage of this structure is the inability to place and stick pictures of greater weight, for example glass or metal, and also its instability with a significant rectangular or square cutout.
The essence of the rectangular or square frame structure according to the invention is that. It is made of a single sheet of three-layer or two-layer material through rectangular or square-shaped cuts forming at least one central support part and cutting the sheet to form trapezoidal leaves over the entire length of each side of the central support part with two cuts to form three folding strands. The middle strand is provided at each end with at least one through hole for fixing the angle connector and in the middle with a hanging hole, while each outer strand has at least one locking leaf and preferably two locking leaves symmetrically arranged at the ends of the strands, the cuts between have the shape of a groove in the middle support part and the inner strand in which the angle between the walls is not less than 135°, on the other hand, the cuts between the inner strand and the middle strand have the shape of a groove in which the angle between the walls is not less than 90°, and the central support part has a recess provided with fastening leaves, preferably trapezoidal and preferably along the entire inner circumference. Fastened to the recess is an inner plate shaped like a recess in the central support part, also provided with fastening leaves, preferably trapezoidal and preferably formed on the entire inner circumference by a groove-shaped cut in which the angle between the walls is not less than 90°.
Preferably, the inner plate with a recess-shaped central support part is made of a transparent or translucent material.
Preferably, the inner strand has narrow leaves on the sides, formed by the removal of the inner layer of a three-layer or two-layer material, leaving the outer layer.
Preferably, the fastening leaves of the middle support part and the fastening leaves of the inner plate are provided with corresponding holes for the detachable fastening elements.
Preferably, the masking plate with longitudinal cuts at the edge is applied to the inner plate in the number and length corresponding to the leaves of the outer strand of the trapezoidal leaves.
Preferably, rectangular pates, preferably of wood or a wood-like material, most preferably of HDF or plywood, connected by side edges to form shelves, are detachably attached to the fastening leaves of the central support part, perpendicular to the middle surface of the support part.
Preferably, the rectangular plates are detachably attached to the attachment leaves of the central support part by their lower edges or upper edges or at their central part.
Preferably, the central support part has a recess provided with elongated fastening leaves, preferably trapezoidal, with a total area similar to the recess of the central support part, between which oblong holes are formed, and preferably along the entire inner periphery, having double, parallel cuts having the shape of a groove, in which the angle between the walls is not less than 90°.
Preferably, the central support part has a recess provided with two rectangular leaves on two opposite sides provided with fixing lugs with holes formed by parallel cuts having the shape of a groove, in which the angle between the walls is not less than 90°.
Preferably, the central support part has a recess provided with one rectangular leaf on one side having two parallel cuts having the shape of a groove, in which the angle between the walls is not less than 90°.
Preferably, the three-layer or two-layer material is a metal-plastic plate in which the material layer has a thickness several times greater than that of the metal layer.
Most preferably, the three-layer material is an ACP board with an aluminum layer thickness of 0.015 mm to 0.5 mm and a PE or LDPE layer of 0.5 mm to 5 mm thickness.
