Description

Description POLE FOR MESH FENCE

Technical Field

[1] The present invention relates to a pole for a mesh fence, and more particularly to a pole for a mesh fence capable of connecting even a twist mesh having a bending property with a strain and maintaining a sleek external appearance without exposing a connecting portion when the mesh is connected and installed. Background Art

[2] In general, a pole for a mesh fence is formed by welding a fixing plate on a lower portion of a long cylindrical support member. The pole is fixed to a basic concrete of the ground through the fixing plate. Then, a standardized mesh is connected between support members.

[3] As an example of the mesh, there are a welded mesh formed by welding horizontal wires and vertical wires and a twist mesh formed by twisting or weaving horizontal wires and vertical wires. However, since the welded mesh and the twist mesh cannot have a connecting means with the pole from the structural characteristics, generally, a number of hook pieces are welded to opposite sides of the support member of the pole and the mesh is connected to the pole using connecting pieces or the like which are manufactured separately from the hook pieces.

[4] Thus, in a process of installing a fence by connecting the mesh between the poles, since it is impossible to assign a strain to the mesh, it cannot be applied to the twist mesh having a bending property differently from the welded mesh. Particularly, since the hook pieces formed at the side of the pole, the connecting pieces serving as a connecting means and a connecting portion are exposed, there are many problems such that an external appearance is not beautiful and an accident may occur due to the exposed connecting portion. Disclosure of Invention

Technical Problem

[5] Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a pole for a mesh fence capable of using a twist mesh having a bending property in addition to a welded mesh by assigning a proper strain to a mesh while the mesh is connected to the pole and capable of maintaining a sleek and beautiful external appearance since a connecting portion of the mesh and the pole is not exposed, thereby preventing an accident due to a sharp connecting portion. Technical Solution [6] The object of the present invention is achieved by a pole for a mesh fence, wherein after the pole is divided into front and rear portions, while a rear support member is installed and fixed to a basic concrete of the ground, the vertical wire of an end portion of a mesh is semi-compulsorily hooked with a number of hook pieces of the rear support member to be connected and fixed thereto with a strain and then the front and rear support members are coupled to each other.

[7] The front and rear support members are formed by splitting a long support member in half. When the front and rear support members are coupled, left and right contact surfaces may be out of joint or a coupling strength may become weak. In this case, the support pieces which enlarge the contact surfaces thereof may be formed to be extended for reinforcement.

[8] When the support members separated into front and rear portions are coupled to each other, the coupling projections of the coupling pieces of the front support member are coupled to the coupling holes of the hook pieces of the rear support member with an elasticity, thereby firmly coupling and fixing the front and rear support members.

[9] Further, as another coupling means of coupling and fixing the front and rear support members, bolt holes are formed on the hook pieces of the rear support member and connecting holes are formed on the front support member. After the front and rear support members are coupled to each other, bolts are fastened through the connecting holes and the bolt holes, thereby firmly connecting and fixing the front and rear support members.

[22] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, wherein like reference numerals refer to like elements throughout. The detailed description of related well-known technologies or functions is omitted to make the point of the invention clear.

[23] FIG. 1 is an exploded perspective view of the present invention. A pole A of the present invention is configured to be divided into front and rear portions. A number of coupling grooves 110 and 210 are formed on left and right contact surfaces of each of front and rear support members 100 and 200. Several coupling pieces 120 having coupling projections 122 are welded and fixed to the inside of the front support member 100. Several hook pieces 220 having hook projections 222 and coupling holes 224 are welded and fixed to the inside of the rear support member 200. The rear support member 200 is connected and fixed to a basic concrete 300 of the ground using a fixing plate 230, and meshes 400 are connected and fixed to the hook pieces 220 of the rear support member 200. Then, the front and rear support members 100 and 200 are coupled and fixed to each other and a cap 500 is coupled and fixed to an upper end of them.

[24] Although the pole A of the present invention is largely configured as long support members and a fixing plate disposed at a lower portion of the support members, the support members 100 and 200 except for the fixing plate 230 have a configuration divided into front and rear portions to avoid a peripheral interference when the support members 100 and 200 are coupled. Further, the fixing plate 230 may be divided into front and rear portions according to all circumstances.

[25] That is, generally, in the installation, the pole A is coupled to an upper portion of the basic concrete 300 of the ground. The pole A is configured such that a fixing bolt of the basic concrete 300 passes through a fixing hole of the fixing plate 230 disposed at a lower portion of the pole A to fix the pole A by tightening a nut. However, in case of twist meshes 400 among meshes capable of being used in the installation of a fence, relatively thick decoration frames 410 and 420 are coupled and fixed to an upper portion and a lower portion of the twist meshes 400 to provide a decoration effect and maintain a strain. Accordingly, when the front support member 100 is coupled to the rear support member 200 which is fixed to the basic concrete 300 in advance, a coupling direction should be maintained horizontally to avoid interference of the decoration frames 410 and 420.

[26] Thus, when the fixing plate in addition to the support members is divided into front and rear portions, it is difficult to couple the front and rear support members. Accordingly, it is preferable to form the fixing plate 230 at the side of the rear support member 200 having the hook pieces 220 in a complete shape without dividing the fixing plate 230.

[27] However, for example, when a mesh without decoration frames is used or when a connecting means of the support members and the basic concrete is varied, it is also possible to divide the fixing plate into front and rear portions. Accordingly, the present invention is satisfied if the support members 100 and 200 are divided into front and rear portions and the meshes 400 are connected therebetween regardless of whether the fixing plate is divided or not.

[28] However, since only the support members 100 and 200 of the pole A are divided into front and rear portions and the fixing plate 230 is welded and fixed to the rear support member 200, a support force of the rear support member 200 may become weak. In this case, an additional reinforcing piece 240 may be welded and formed between the rear support member 200 and the fixing plate 230 to reinforce the strength.

[29] Further, a cross-sectional shape of the front and rear support members 100 and 200 of the pole A may be formed in various shapes such as a shape or a shape in addition to a semicircular shape. However, if stand projections are formed at opposite sides of the inside thereof in a longitudinal direction, the coupling pieces 120 and the hook pieces 220 can always be welded and fixed to a specified position.

[30] Further, when support pieces 150 and 250 which enlarge left and right contact surfaces are formed to be extended at opposite sides of the front and rear support members 100 and 200, the coupling and strength reinforcement of the front and rear support members 100 and 200 can be stably and firmly performed. A number of coupling grooves 110 and 210 formed on the left and right contact surfaces are formed to face each other. When the meshes 400 are connected and installed, horizontal wires 430 of the meshes pass through the coupling grooves 110 and 210 with a slight margin.

[31] Further, when the front and rear support members 100 are formed vertically since the height of a desired fence is high, a number of through holes are formed on the support pieces 150 and 250 disposed at opposite sides of the front and rear support members 100 and 200 away from the coupling grooves 110 and 210. After the front and rear support members 100 and 200 are coupled to each other, it is possible to further reinforce a coupling force of the front and rear support members 100 and 200 by fastening bolts and nuts via the through holes or riveting.

[32] FIG. 2 illustrates the coupling piece formed on the front support member of the pole and the hook piece formed on the rear support member. The coupling projections 122 are formed to be protruded at upper and lower portions of a front surface of a main body of each coupling piece 120 welded and fixed to the front support member 100. Inclined hook projections are formed to be protruded on outer surfaces of the upper and lower coupling projections 122, respectively. When the front and rear support members 100 and 200 are completely coupled to each other, the hook projections of the coupling projections 122 are hooked by edge portions of the coupling holes 224 of the hook pieces 220 of the rear support member 200, thereby maintaining a strong coupling force therebetween.

[33] Further, one or more coupling projections 122 are formed to be protruded at opposite sides of a main body of each hook piece 220 welded and fixed to the rear support member 200. The left and right coupling projections 122 are formed to be protruded and inclined toward an inner front side, thereby being stably and firmly coupled to left and right meshes 400.

[34] FIGS. 6 and 7 illustrate another embodiment of the present invention, wherein the front and rear support members are formed to have narrow left and right contact surfaces.

[35] That is, when the support pieces are formed to be extended at opposite sides of the front and rear support members, the strength of the front and rear support members is reinforced. However, even though the support pieces are removed, the support members of the pole can have a sufficient strength required for the support members of the pole due to the stand projections formed and bent at opposite sides. Further, when the front and rear support members are coupled to each other, it is possible to maintain a sleek and simple external appearance.

[36] FIGS. 8 and 11 illustrate another embodiment of the present invention, wherein bolts are used as a coupling means of the front and rear support members.

[37] Bolt holes 226 are formed to hook pieces 220' of a rear support member 200'. A number of connecting holes 170 are formed on a front support member 100' to communicate with the bolt holes 226 of the hook pieces 220' of the rear support member 200'. After the front and rear support members 100' and 200' are coupled to each other, bolts 600 are fastened to the bolt holes 226 through the connecting holes 170, thereby maintaining a strong coupling force between the front and rear support members 100' and 200' which are coupled to each other.

[38] However, since the front support member 100' does not have an additional connecting means between the left and right contact surfaces, when a strong tightening force of the bolts 600 is applied to the front support member 100' in a coupling process of the front and rear support members 100' and 200', deformation may occur. Stand pieces 228 are formed to be protruded at lower opposite sides of the hook pieces 220' of the rear support member 200'. When the front and rear support members 100' and 200' are coupled to each other, the stand pieces 228 are in contact with an inner wall of the front support member 100' to support the front support member, thereby preventing the deformation of the front support member 100'.

[39] Various embodiments may be provided to connect the divided front and rear support members. The present invention is satisfied if the front and rear support members 100 and 200 are separated and the meshes 400 are connected therebetween.

[40] FIG. 3 illustrates the installation of a fence according to the present invention. In the installation of a fence using the pole A of the present invention, first, the rear support member 200 is connected and fixed to the basic concrete 300 of the ground using the fixing plate 230. The horizontal wires 430 of the meshes 400 are coupled to the coupling grooves 210 of the rear support member 200. Then, the vertical wires 440 of end portions of the meshes 400 are semi-compulsorily hooked with left and right hook projections 222 of the rear support member 200 to be connected and fixed thereto. Then, the front and rear support members 100 and 200 are coupled and fixed, and the cap 500 is coupled and fixed to the upper end of the pole A, thereby completing the installation.

[41] The pole A used in the above case is connected and fixed to the basic concrete 300 through the fixing plate 230 of the rear support member 200 among the support members 100 and 200 divided into front and rear portions. However, the reinforcing piece 240 is connected and formed between the rear support member 200 and the fixing plate 230 to reinforce a supporting strength of the rear support member 200. Thus, it is possible to maintain a sufficient strength required for the pole A for a fence.

[42] Further, in the installation of the poles A, the poles are fixed and installed such that a distance between the poles is maintained to be slightly larger than the length of the standardized meshes 400. In a connecting operation of the meshes 400, when the vertical wires 440 of the end portions of the meshes are semi-compulsorily hooked with the hook projections 222 of the hook pieces 220 of the rear support member 200 to be connected and fixed thereto with a strain, the meshes 400 are maintained with a tight strain between the poles A. Accordingly, it is also possible to use the twist meshes 400 with a self elasticity in the installation of the fence.

[43] Further, when the front and rear support members 100 and 200 are coupled to each other, the upper and lower coupling projections 122 of the coupling piece 120 of the front support member 100 are coupled to the coupling holes 224 of the hook pieces 220 of the rear support member 200 with an elasticity. In this case, the hook projection formed to be protruded and inclined at the outside of the upper and lower coupling projections 122 are hooked with edge portions of the coupling holes 224. Further, after coupling, the cap 500 is coupled and fixed to the upper end thereof, thereby maintaining a strong coupling force when the front and rear support members 100 and 200 are coupled. In this case, the horizontal wires 430 of the meshes 400 pass through the coupling grooves 110 and 210 formed at the left and right contact surfaces of the front and rear support members 100 and 200. Also, connecting portions of the meshes 400 and the coupling pieces 120 and the hook pieces 220 of the front and rear support members 100 and 200 are positioned in the front and rear support members such that they are not exposed in the external appearance, thereby maintaining a sleek external appearance.

[44] FIGS. 8 and 11 illustrate another embodiment of the present invention. Also in this case, the rear support member 200' is fixed and installed on the basic concrete 300'. Then, vertical wires 440' of end portions of left and right meshes 400' are semi- compulsorily hooked with left and right hook projections 222' of the hook pieces 220' to be connected and fixed thereto with a strain. After the front and rear support members 100' and 200' are coupled to each other, bolts 600 are fastened to the bolt holes 226 of the hook pieces 220' of the rear support member 200' through the connecting holes 170 of the front support member 100'. Thus, the front and rear support members 100' and 200' are firmly coupled and fixed to each other.

[45] Further, when the front and rear support members 100' and 200' are coupled and fixed to each other, the left and right stand pieces 228 of the hook pieces 220' of the rear support member 200' are in close contact with an inner wall of the front support member 100'. Accordingly, when the bolts 600 are firmly fastened to couple the front and rear support members 100 and 200, it is possible to prevent the deformation of the front support member 100. Thus, the above configuration can function as a pole for a mesh fence without exposing the connecting portions of the meshes 400' while maintaining a sleek external appearance. Industrial Applicability

[46] According to the present invention, the pole A is divided into the front and rear sup port members 100 and 200, and the meshes 400 are connected thereto through the hook pieces 220 of the rear support member 200. Then, the front and rear support members 100 and 200 are coupled and fixed thereto. While the meshes 400 are connected to the pole A, a sufficient strain can be assigned to the meshes 400. In the installation of the fence using the pole A of the present invention, the twist meshes 400 with a bending property may be also used in addition to the welded mesh. Particularly, the connecting portions of the meshes 400 are not exposed at all, thereby maintaining a sleek and beautiful external appearance. Also, there is an effect of preventing an accident due to a sharp connecting portion.

[47] Although the preferred embodiment of the present invention has been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
