Technical field
The present invention relates to a fencing panel used, among others, in fencing spans of metal fences in a transverse position. State of Art
Fences that are made, among others, of panels in the form of closed hollow aluminium sections are known in the prior art, an example being a solution by the fence manufacturer, Zalu sp. z o.o., available on the website: [https://zalu.pl/ogrodzenia] A fence profile is known, as disclosed in the Polish patent description PL 214817 Bl, comprising interconnected sections with a spatial structure that form a closed profile, the front section having inwardly-facing channel-like bends, and the other section also having inwardly-facing channel-like bends which enter, on both sides, the slots of at least one connector that is situated inside the profile, and the front section being pinned in the same slots of the connector, preferably by means of a snapped connection.
A fencing system is known from the Polish patent description PL 204579 Bl which is provided, among others, with a section for vertical rungs and/or a section for crossbars consisting of at least two mutually overlapping portions which, when interconnected, form a closed profile. The system is also characterized in that the profile of one portion consists of a front surface which bends inward to the section on both sides to form an inlet for the other portion. The profile of the other portion has the shape of a gutter that is adapted in shape and dimensions to the inlet formed in the first portion. A segmented fencing system is known from the Polish patent description PL 233834 B1 which is provided with channel-shaped panels with perpendicularly bent ends of panel arms. In order to enhance the visual effect, masking panel segments are arranged in the panel on the rear side thereof.
A fencing field filling element with a closed profile is known from the application description P.376512, which consists of two architectural details symmetrical to each other, each of the portions having edges in the form of flat slats, the width of a slat of one architectural detail being two times the width of a slat of the other architectural detail, and the wider slat being bent at an angle of 180°. Both architectural details are interconnected by sliding one slat into the other.
Summary of Invention
The aim of the present invention was to develop a fencing panel formed of two separate sections that are detachable during assembly, which facilitates and accelerates the assembly of the span, and once connected, form a uniform flush fencing panel. The arms of the panel sections form specially designed locks that allow for easy assembly of the sections with each other and limit the possibility of water penetration and soaking into the panel. Additionally, the panel is made of a thin sheet with a thickness of 0.5 mm coated with a colour layer, which reduces the weight of the finished product without reducing its rigidity. The panel is structurally reinforced by profiling the two sections integrated therewith, with a filling material is arranged detachably between them. Such a structure of the panel results in it being rigid, reinforced and, at the same time, lightweight. Most of the commonly available fencing panels are usually made of a raw material with a thickness of 0.7 mm to ensure the rigidity of the element.
