Description

Fencing panel

Technical field

The present invention relates to a fencing panel usable, 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 aluminum 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 from the Polish patent description PL 214817 B1 which comprises interconnected sections with a spatial structure that form a closed profile, the front section having inwardly-facing channel-like bends, and the other of the sections 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 B1 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 that 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 inserting 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 the sections to be assembled together easily and limit the possibility of water penetration and rise into the panel to its maximum, which in turn prevents corrosion inside the element due to capillary rise.

Additionally, the panel is made of a thin, coated sheet with a thickness of 0.5 mm, which reduces the weight of the finished product without reducing its rigidity. The panel is structurally reinforced by roll-forming the two sections integrated therewith, between which filling material is arranged detachably. Such a structure of the panel results in it being rigid, reinforced, and, at the same time, light-weight. Most of the commonly available fencing panels are usually made of raw material with a thickness of 0.7 mm in order to ensure the rigidity of the element. In addition, the press-fit assembly eliminates the possibility of scratching the panel elements being joined. Solution of Technical Problem

The solution addresses a technical problem concerning the elimination of additional connecting elements, such as e.g. rivets, screws, or welds, when connecting the sections that form the panel.

Description of Embodiment

The fencing panel 1 according to the present invention is made of a corrosion- resistant material, most preferably galvanized steel sheet coated with an organic coating, and consists of a front section 2 and a rear section 3 that are interconnected detachably. The front section 2 with a cross-section resembling the letter C consists of a longer arm 2.2. and a shorter arm 2.5., in the form of slats connected together by a front surface 2.1. The longer arm 2.2. of a width si = 24 mm is tangential to the additional arm 2.3. of a width S₂ = 10 mm, inclined to the front surface 2.1. at an acute angle a = 84 °, the additional arm 2.3. being tangential to the final arm 2.4. of a width S₃ = 10 mm, inclined at an acute angle b = 65°, and the angle b is set between the bending P of the additional arm 2.3. and the final arm 2.4., wherein the bending P, of a width S₄ = 7 mm, additionally covers, from the inside, the surface of the longer arm 2.2. The outer radius of roundnesses of the additional arm 2.3 and the final arm 2.4., and of the bending P of the additional arm 2.3. is Ri = 1 mm, and the outer radius of the roundness of the bending P of the final arm 2.4. is R₂ = 0.5 mm.

The shorter arm 2.5. of the front section 2 comprises an additional arm 2.6. of width S₆ = 10 mm that is perpendicular relative thereto, and the width S₅ of the shorter arm 2.5. is determined in such a way that, after forming the closed profile of the fencing panel 1, i.e. joining the front section 2 with the rear section 3, the additional arm 2.6. of the shorter arm 2.5. is tangential with its open end to the bend comprising the connection of the inner wall 3.4. and the outer wall 3.5. of the bend 3.3. of the rear section 3, at a point determined as half of the distance I between the inner wall 3.4. and the outer wall 3.5.

The rear section 3 consists of an arm 3.2. and a bend 3.3. in the form of slats connected by a rear surface 3.1. The arm 3.2. of the rear section 3 of a width

57 = 25 mm is deflected at an angle g = 123 ° relative to the rear surface 3.1. of the rear section 3, set between the bendings P of the arm 3.2. of the rear section 3 and the rear surface 3.1. The bending P of the arm 3.2. of the rear section 3 additionally covers, from the inside, the surface of the rear surface 3.1. at a width

5₈ = 12 mm. The outer radius of the roundness of the arm 3.2 and the roundness of the bending P at the point of contact with the rear surface 3.1. is Ri= 1 mm, and the outer radius of the roundness of the outer bending P of the arm 3.2. is R2 = 0.5 mm. The bend 3.3. of the rear section 3 is formed by a double bend, forming a pair of walls, an inner wall 3.4. of a width sg = 10.5 mm and an outer wall of a width sio = 10 mm, parallel to each other and to the rear surface 3.1., wherein the inner distance between the inner wall 3.4. and the rear surface 3.1., and between the inner wall 3.4. and the outer wall 3.5. is I = 2 mm, and the radius of roudnesses of these walls is R = 1 mm. The width S₆ of the additional arm 2.6. is equal to the height h_sz of the slot Sz formed between the pair of the inner wall 3.4. and the outer wall 3.5. of the double bend 3.3. of the rear section 3. The space of the panel 1 that forms the closed profile, encompassing the area between an assembly of locks formed by the arm 3.2. of the rear section 3 and the longer arm 2.2., the additional arm 2.3. and the final arm 3.3. of the front section 2, and an assembly of locks formed by the shorter arm 2.5. and the additional arm 2.6. of the front section 2 and the bend 3.3. of the rear section 3, in a cross-section resembling a rectangular trapezoid, is filled detachably, within a tolerance of ±0.3 mm, with the filling material 4 in the form of expanded polystyrene that dampens sound, as well as prevents excessive and undesirable inward bending (deformation) of the front surface 2.1. of the front section 2 and the rear surface 3.1. of the rear section 3.

Industrial Applicability

In order to assemble the fencing panel 1 according to the invention, the filling material 4 is arranged on the front section 2 which is positioned flat on the front surface 2.1. by appropriately orienting (positioning) the filling material 4 and press-fitting it into the space of the front section 2, and then the panel 1 is assembled into the closed profile by applying and inserting the slot Sz, located between the inner wall 3.4. and the outer wall 3.5. of the bend 3.3. of the rear section 3, on the additional arm 2.6. of the shorter arm 2.5 of the front section 2; next, it bends the arm 3.2. of the rear section 3 by slightly reducing the angle y of the rear section 3, then it pushes the arm 3.2. under the final arm 2.4. of the front section 2, in such a way that in the closed profile of the panel 1, the surface of the additional arm 2.3. of the front section 2 is flush with the rear surface 3.1. of the rear section 3, and the angle a of the longerarm 2.2., the angle b of the final arm 2.4., and the angle y of the arm 3.2. of the rear section 3, as a result of mutual stress and elasticity of the steel sheet, have the effect of 90 ° alignment of the elements (the front section 2 and the rear section 3) forming the fencing panel 1. The structure of the locks also enables the rear section 3 to be inserted into the front section 2.
