Description

The present invention relates to fences, for example fences from a picket fence, and can be used to fence household plots, gardens, squares, etc.

A known fence made of plastic hollow shtaketin, in the lateral faces of which holes are made. Every two adjacent shtaketin are connected by docking units having docking grooves, in which fasten the connecting elements inserted into the holes of two adjacent shtaketin. The connecting elements are inserted into the holes of the shtaketin and into the grooves of the docking nodes. Each connecting element contains a first channel element. In the side face of each shtaketin there is a second channel element, combined with the first channel element and fastened with fasteners for fastening the shtaketin to the docking station (see US patent No. 5492307, publ. 02.20.1996).

As it is obvious, the structure of the shtaketin is complex, and its manufacture is not technologically advanced. In addition, with such a design of the shtaketin, it can be used only for a continuous fence, which reduces the possibilities of artistic construction of fences.

A known fence of plastic elements and the method of its construction (see US patent No. 5613664, publ. March 25, 1997), selected as the closest in technical essence to the claimed object as a prototype. The fence contains hollow shtaketin and two hollow veins. An reinforcing element is inserted inside each shtaketin, the opposite ends of which protrude from the corresponding ends of the vein. The internal cavities of the inserted shtaketin and vein are filled with plastic hardening material, which, spreading inside these cavities, completely fills them and surrounds the reinforcing elements.

Shtaketins of this design can only be attached to hollow veins, which limits their use. In addition, shtaketin is structurally complex, and the necessary structural rigidity is achieved not only by the reinforcing element, but also by filling the shtaketin cavity with plastic hardening material, which leads to additional consumption of plastic materials and increases the cost of the structure. Also, when using shtaketin of this design, the possibilities of artistic design of fences are limited.

A known method of manufacturing a hollow polyvinyl plastic strips obtained by the extrusion method (see US patent No. 6478287, publ. 12.11.2002). All planks are glued to one adjacent plastic glue, i.e. form a continuous panel of the fence.

The strips obtained by this method do not have sufficient rigidity, therefore, to give the panels the necessary rigidity, the strips are glued together, and the veins are reinforced with horizontal strips, which complicates the design and reduces the design possibilities of the fence.

A known method of manufacturing elements of the fence of thermoplastic resin by injection of this resin into the formwork (see Japanese patent document No. 2792624 B2, 8296348 A, publ. 09/03/1998, priority 04.25.1995, selected as the closest to the claimed method in as a prototype.

The use of the formwork method allows the manufacture of fence elements of any configuration, however, the enclosing plate obtained by this method has a continuous structure, which does not allow diversifying the design of the fence. The rigidity of the structure when implementing this method is achieved due to the continuity of the slab and placing it between the veins and the pillars of the fence, which also reduces the possibility of artistic design of the fence.

The present invention is based on the task of creating a shtaketin and a method for its manufacture in such a design and using such a technology for producing it from a polymeric material to ensure the convenience of fastening the shtaketin to the veins of the fence while achieving the necessary stiffness of the shtaketin and increasing the manufacturability of its manufacture, as well as expanding its capabilities the use of shtaketin in the artistic design of fences.

This problem is solved by the fact that in a shtaket made of hollow polymer material, according to the invention, the cross-section of the shtaketin is made rectangular, inside the shtaketin perpendicular to its planes and parallel to the side ends there are hollow ribs spaced along the length of the shtaketin, while part of the ribs adjacent to the planes shtaketin made cone-shaped, the base facing the planes of the shtaketin, and the tops of the cone-shaped parts are conjugated, with the formation in the middle part of the ribs concave the surface.

This embodiment of the shtaketin allows to increase the stiffness of the shtaketin by placing hollow ribs spaced along the length of the shtaketin in its cavity. Moreover, the configuration of the ribs allows you to use them to connect the shtaketin to the veins. The length and width of the shtaketin can vary widely, which allows a set of different shtaketin to artificially design fences.

According to one embodiment of the shtaketin, at least one rib is installed along the shtaketin width.

This embodiment shtaketin allows you to use shtaketin different widths, without reducing their rigidity. For a narrow shtaketin, only one rib is enough, for wider, they can be correspondingly more.

According to another embodiment of the shtaketin, it is advisable to install at least two ribs along the shtaketin length, which makes it possible to use not only short shtaketins, for which it is sufficient to install two ribs (for attaching the shaktetin to two veins of the fence), but also longer ones, for example, when using them for constructing fences with three or more veins.

According to another embodiment of the shtaketin, it is advisable to perform the cone-shaped part of the ribs with dimensions and taper, comparable with the size and taper of the fasteners used to connect the shtaketin to the vein of the fence. This allows you to increase the density of the connection of the fastener with the rib.

According to another embodiment of the shtaketin, it is advisable to reinforce the side ends of the shtaketin with a reinforcing element, for example, a metal plate placed in the thickness of the side ends of the shtaketin. This embodiment of the shtaketin allows the use of polymeric materials with low rigidity, as well as to increase the stiffness of the shtaketin in the case of using long shtaketin.

According to another embodiment of the shtaketin, it is advisable at the ends of the shtaketin to carry lock elements spaced along the length of the shtaketin.

This embodiment of the shtaketin allows the assembly of shtaketin at the place of its attachment to the veins, as well as simplify the technology of manufacturing shtaketin. In this case, the locking elements can have a different design and can be made both from the material of which the shtaketin is made, and from other materials, for example, in the form of overhead metal locking elements.

This problem is also solved by the fact that in the method of manufacturing shtaketin by casting it from a polymer material, according to the invention, two symmetrical shtaketin halves with a plane of symmetry perpendicular to the side ends of the shtaketin are cast, after which both halves are fastened together.

This embodiment of the method allows the most technologically advanced way to perform the ribs in the cavity of the shtaketin.

According to one embodiment of the method, it is advisable to cast lock elements spaced along the length of the shtaketa at the ends of the shtaketin.

This embodiment of the method improves both the manufacturability of the shtaketin and the manufacturability of its assembly directly when attaching the shtaketin to the veins.

According to another embodiment of the method, it is advisable to attach overhead locking elements made, for example, of metal, to the ends of the shtaketin.

This embodiment of the method expands the possibilities of its application. Metal locking elements also serve as additional nodes that increase the rigidity of the shtaketin.

According to another embodiment of the method, it is advisable to bond the halves of the shtaketin by gluing. In another embodiment, bonding is done by heating the edges of the halves of the shtaketin and softening them, followed by pressing the softened edges. The use of polymeric materials makes it possible to apply various methods of bonding halves of shtaketin depending on the technological capabilities and applied plastics.

According to another embodiment of the method, it is advisable to add a dye before casting shtaketin into the polymer material, thereby achieving the artistic diversity of the fence obtained from shtaketin.

The above and other advantages, as well as features of the present invention will be better understood after consideration below, a detailed description, accompanied by drawings, in which

figure 1 depicts a shaketin with three ribs spaced along the length, and one rib installed along the width of the shaketin, according to the invention

figure 2 is a section I-I of figure 1;

Figure 3 - section II-II of figure 1;

figure 4 depicts a shtaketin with three pairs of ribs spaced along the length of the shtaketin, according to the invention;

Fig.7 - node C in Fig.6 is one of the locking elements spaced along the length of the shtaketin, in an enlarged size.

Shtaketina 1 (in the direction of the arrow) (Fig. 1) is made hollow from a polymeric material with a rectangular cross section. Inside the shtaketina 1, perpendicular to its planes 2 and 3 (Fig. 2) and parallel to the side ends 4 and 5 (Fig. 3), ribs 6 are spaced along the length of the shtaket 1. The parts of the ribs 6 adjacent to the shaktan planes 2 and 3 are conical forms, with the base facing the shaketin planes 2 and 3, and the vertices of the conical parts are conjugated and form a concave surface 7 in the middle part of the ribs 6.

The cone-shaped part of the ribs 6 has dimensions and conicity commensurate with the dimensions and conicity of the fastening elements (not shown in the drawings) used to connect the shtaketin to the vein of the fence. The ends 5 and 4 (figure 3) can be reinforced with an amplifying element (not shown in the drawings), for example, a metal plate placed in the thickness of the side ends of the shtaketin.

Figure 4 shows the shtaketin 8 (arrow), similar in design to shaketin 1 (Fig. 1), but with a large number of ribs 9 (Figs. 4, 5, 6), namely with three pairs spaced along the length of the shtaketin. Figures 5 and 6 show planes 10 and 11, and Fig. 6 shows the ends 12 and 13 of the shtaketin 8. A concave surface 14 is formed in the middle part of the ribs 9.

The number of ribs installed along the length and width of the shtaketin can be different and depends on the length and width of the shtaketin.

A method of manufacturing a shtaketin consists in casting two symmetrical halves of a shtaketin with a plane of symmetry perpendicular to the side ends of the shtaketin, and then fastening them by locking elements, gluing or softening the edges of the shtaketin and pressing the softened edges. The method of bonding halves of shtaketin depends on the polymer material used for casting and technological feasibility. In figures 2 and 3, line A, and in figure 5, line B conditionally shows a seam along which both halves of the shtaketin are connected.

Fig.7 shows an enlarged view of the node C in Fig.6. The halves of the ends 12 are made with a locking element 15. The number of locking elements 15 depends on the length of the rod. The locking elements can have a different design, for example, such as shown in Fig.7, as well as be made of various materials, and not just the material from which the shaketin is made. The locking elements can be cast at the same time as shtaketin casting or performed by waybills made of metal or other materials.

The upper ends of the shtaketin can have a flat, pointed or rounded shape.

An advantage of the present invention is the achievement by simple means of the necessary rigidity of the shtaketin, the convenience of its use in various combinations, the manufacturability, the ability to produce shtaketin of various sizes and differently colored, which increases the design capabilities in the manufacture of fencing using the proposed shtaketin.

According to the applicant, the proposed solution meets the criteria of the invention, being new, industrially applicable and having an inventive step.
