Definitions

  • the present invention relates to fence structures, in particular having vertical posts with horizontal crossbars, and to their assembly, as generaly shown in EP1655428B .
  • the invention discloses the structure of the segmental fence comprising rigid crossbars made of sheet material (e.g., profiled sheet metal) and an efficient method of assembling such a fence.
  • the most common structure of fences consists of a series of vertical posts connected by horizontal crossbars or panel elements mounted between the pairs of posts, or other types, design and structure segments installed between the posts of the fence.
  • U.S. Pat. US3195864A (15-03-1962 ) describes a fence constructed of posts and crossbars, which is all metal, easy to assemble, solid structure, attractive and pleasing to the eye.
  • Another object of the present invention is to provide factory-made high quality and economical components that can be easily assembled outdoors and thus enabling to assemble a strong metal fence from the crossbars, suitable for a variety of situations and with minimal labor costs.
  • the structure of the fence consists of: the vertical, rectangular cross-section post with at least one engagement groove on the surface; a horizontal tube connected to the post and capable of moving sideways and vertically; a first connecting bracket movably connected to the post engagement groove and movable sideways; a pair of second connecting brackets mounted on the horizontal end of the tube and suspended from the first connecting bracket to move vertically; and a hinge pin for coupling the first and the second connecting brackets.
  • FIG. 1 Another U.S. patent US7090201B2 describes a fence structure system, consisting of strong and durable polymeric components, provided as an integrated modular kit that is easy to assemble in a DIY way.
  • the modular fence is an integrated system of compatible vinyl components using a unique polycarbonate or ABS-plastic clamp.
  • the fence consists of vertical posts with horizontal elements mounted between them. The horizontal elements have grooves for pressing in and holding the fence panels. Horizontal elements are connected to vertical elements using a new and uniquely configurable connecting element.
  • aluminum fences are known similar in structure to those described in KR101910532B1 and US7090201B2 , but differ in that the horizontal crossbars of the fence are not round or square aluminum tubes but elements of other cross-sectional shapes, such as flat blind-shaped aluminum profiles.
  • fence structures made of sheet metal and profiled sheet metal panels.
  • Profiled sheet metal structures, rails and panels are light but durable, they can be galvanized and painted with special durable and resistant paints.
  • Profiled sheet metal improves the strength of the fence structure.
  • U.S. Pat. US20180058092A1 A fence that completely covers the view is described in U.S. Pat. US20180058092A1 , in which the structure consists of interconnected vertical fence panels mounted between horizontal guide rails.
  • an improved connector of the vertical panel elements is disclosed, which connects the vertical panels into a single fence panel between the horizontal rails, while the vertical panels interlock and are no longer separate, thus enhancing the integrity and stability of the fence.
  • the fence plinth is made of a sheet material, which in one embodiment is pre-painted galvanized steel, has end edges and is profiled with stiffening formations running along the sheet between the end edges.
  • the plinth is ideal for use in conjunction with a fence consisting of posts connected by horizontal channels in which the edge of the plinth can be inserted.
  • the method of forming the plinths is also described.
  • profiled sheet metal segmental fences assembled using rivets and professional tools.
  • the assembled and riveted profiled sheet metal segments are transported to the destination and installed in the fence line, each segment being installed between the pairs of vertical posts of the fence.
  • the production, assembly and transportation of such structure segments is complex, requires professional tools and skills, and can only be serviced by qualified professionals.
  • the structure and method of assembly of such a fence segment comprising horizontal profiled sheet metal crossbars joined by rivets or screws are known and are shown in Fig. 1 .
  • fence structures are numerous and differ in functional characteristics, such as contemporary fashion, design and adaptability to customer tastes, safety, durability, resistance to adverse climatic conditions and an efficient delivery and assembly process.
  • Profiled sheet metal fence structures and kits have recently become popular because they have many advantages over other fence structures.
  • profiled sheet metal fence structures and assembly methods are not efficient enough and require professional technical actions, such as: riveting, special transportation of assembled segments, teams of several qualified specialists to properly install the delivered segment in the fence line.
  • Warranty and post-warranty service is also complicated.
  • fence segments assembled by riveting from profiled sheet metal have disadvantages in terms of durability and resistance to climatic factors such as seasonal temperature fluctuations. For example, after a few years, a riveted segment of a fence may come apart due to breakage / rupture of the rivets under influence of climatic thermo-mechanical stress.
  • the present invention discloses the structure and assembly method of a segmental fence made of profiled lamellas.
  • the segment of the fence consists of horizontal crossbars, or lamellas, made of profiled sheet metal or metal sheets folded in cross-sectional profiles of the chosen shape.
  • the cross-sectional shape of the lamellas is chosen by taking into account the design and functional factors of the fence, such as visibility through the fence or transmission of sunlight.
  • the fence segment consists of two vertical trough-shaped metal rails attached to the fence posts.
  • the structure uses special connecting elements to ensure firm stacking of the horizontal lamellas on top of each other and rigid connection within the segment; also, the base structure, the top cover (covers for posts and / or covers for the whole segments), and the protective and fixing elements.
  • the horizontal bars (lamellas) of the fence segment are bent from high-quality sheet metal or other sheet and / or metal material.
  • the sheet metal can be galvanized and coated with special paints, which give the lamella a good appearance
  • the assembly process of this segmental fence is efficient, starting with preparation of the structural elements (the vertical rails, the horizontal lamellas, the connecting elements, the base, the covers and the protective fastening elements).
  • the fence segment kit is provided in a compact package that can be conveniently delivered to the destination by one person.
  • the assembly of the fence segments is performed according to a simple instruction that does not require professional tools or operations (such as bending, painting, drilling or riveting).
  • Sufficient tools are a standard electric screwdriver and a level measuring tool (spirit level). According to these instructions, the fence installation technician or the customer himself, who has minimal technical skills, can independently install any segment of such structure.
  • the assembled and installed fence segment is resistant to adverse climatic conditions, such as sudden changes in temperature, humidity, and wind.
  • the segment is rigid and resistant to deformations due to short-term mechanical impact, such as the impact of a children's play ball.
  • the vertical sheet metal rails and horizontal lamellas are coated with special anti-corrosion materials that protect the surfaces and ensure a long-term service life of the components.
  • the structure of the segment and the method of assembly allow for a variety of fence shapes and designs. This variety is characterized by the different shapes of the horizontal lamella profile, which allows the implementation of different fence configurations, such as roofs, blinds, with clear acrylic inserts (boxes) and the like.
  • the fence of this structure is disassembled as easily as it is assembled, so it can be moved and re-installed in another location. As with the assembly, disassembly does not require professional tools and skills.
  • the fence consists of a series of vertical posts or poles (3) spaced at a predetermined distance from each other.
  • Posts (3) can be made or built of brick, concrete, wood, metal or other suitable structures and materials.
  • the material and structure of the vertical posts (3) is not essential for the installation of the fence segment (1), since the fence segment (1) is assembled (arranged) into two vertical rails (6) belonging to the segment, which are previously attached to said vertical posts (3).
  • the fence may also have a base or foundation (2).
  • the base / foundation (2) is usually cast of concrete and can also be constructed or formed of wood, metal, brick or other suitable materials.
  • the foundation (2) may be useful / suitable as a base for placing (arranging) on it the horizontal crossbars / lamellas (4) of the fence segment together with the connecting elements (5).
  • an important feature of the fence base (2) is its smooth and horizontal upper surface, so that the crossbars / lamellas (4) of the fence segment, laid and stacked on the surface of the base (2), are exactly horizontal. Otherwise, if the foundation of the fence is not horizontal and level, then the horizontality of the crossbars / lamellas (4) must be ensured by other means.
  • the vertical rails (6) of the fence segment (1) are designed to make a stack of horizontal crossbars / lamellas (4) and their connecting elements (5).
  • the vertical rail (6) is U-shaped and its width corresponds to the width of the horizontal crossbar / lamella (4) and the connecting element (5).
  • the profile of the vertical rail (6) may have the cross-sections shown in Figures 8 a-b .
  • the vertical rails (6) can be made of thick (for example, 1.5 to 2 millimeters thick) sheet metal, which is preferably galvanized and painted with paint for durability.
  • the vertical rail (6) may have a lower support (10) for supporting and holding the stack of horizontal crossbars / lamellas (4) with connecting elements (5).
  • the support (10) is required if there is no cast fence foundation (2), or if the cast foundation (2) is uneven, or if the top surface is not horizontal enough to support and put horizontal crossbars / lamellas (4).
  • the vertical rail (6) is attached to the vertical post (3) of the fence with bolts, screws, nails or other suitable means. Accurate alignment of the two vertical rails (6) is required when the vertical rails (6) are used not only to place the horizontal crossbars / lamellas (4) in the stack, but also to ensure the horizontal alignment of said stack using the lower supports (10) of the vertical rails (6).
  • the set of horizontal crossbars / lamellas (4) are arranged in two vertical rails (6) by means of connecting elements (5).
  • the choice of design and shape of the fence segment (1) and the horizontal lamella (4) can take into account the direct visibility through the fence and the transmission of sunlight at different times of the year.
  • the connecting elements (5) are one of the essential elements of the present invention. These elements ensure easy assembly of the segment (1), as well as give the horizontal crossbars / lamellas (4) a "freedom" clearance (9) for thermal expansion and contraction.
  • the connecting elements (5) are made or cast or 3D-printed from polyvinyl, polyethylene, polypropylene plastics or their composites or other suitable materials. In one suitable embodiment, the plastic composite comprises a mixture of 80% polyethylene and 20% polychlorovinyl.
  • the assembled stack of horizontal crossbars / lamellas (4) is fastened from above with lids (8) or with the upper beam or cover (14) of the segment.
  • the fastening lid (8) is fixed above the connecting element (5), and no longer allows the elements (5) below the vertical rail (6) to move, and at the same time no longer allows the fence segment (1) to be dismantled.
  • the fence segment (1) comprises horizontal crossbars / lamellas (4). These are the components that perform the essential function of the fence segment (1). Where appropriate, they are made (folded) of profiled sheet metal, but can be cast from aluminum, made of sheet metal, of glued moisture-resistant wood, plastic and other suitable materials.
  • the main feature of the element / lamella (4) is the use of a three-dimensional thin-walled profile, which allows to obtain a large covering area, lamella strength and stiffness, low weight and various functional shapes with a small amount of raw material.
  • the thickness of the sheet metal suitable for the production of horizontal lamellae profiles (4) can be selected from 0.4 to 1.00 millimeters.
  • the outer surface of the tin profile is covered with paint: polyester, imitation of wood or other.
  • the sheet metal can be galvanized, in which case the surface is extremely resistant to environmental influences, such as rain, wind and temperature changes.
  • the segment of the profiled sheet metal fence is rigid and light. It is resistant to many typical mechanical impacts (for example, impacts when children play with the ball, strong winds, etc.).
  • the length of the horizontal crossbars / lamellas and fence segment using sheet metal profiling technology can reach 3-4 meters. Proper coating, painting and element materials ensure the longevity of the fence up to 30 years.
  • the horizontal crossbar / lamella (4) is made by folding the sheet metal into the selected cross-sectional profile.
  • Each particular cross-sectional shape can also perform a specific function.
  • a fence with horizontal crossbars / lamellas (4), the profiles of which are shown in Figures 5a, 5b, 5c can be used:
  • the shape of the horizontal crossbar / lamella (4) is selectable. This means that the lamella (4) and its connecting elements (5) can be designed and manufactured according to individual shapes desired by the customer. Practical versions of profiles are presented in Figure 5 . (a-k). Some profiles can be reinforced and stiffer in structure. For example, Figure 5c shows a reinforced modification of profile depicted in Figure 5b. Figures 5 i, k show the changes for strengthening the profile structure depicted in Figure 5g . In the fence segments, any of the profile versions shown can be used for horizontal crossbars (4) with a standard length (1800 millimeters) or less. For crossbars / lamellas (4) with a selected length exceeding 1800 millimeters, only reinforced versions are recommended ( Fig.
  • the connecting element (5) is essential in the present invention and is shown in Figure 3 .
