Applicant hereby incorporates by reference the subject matter of Republic of Korea Patent Application No. 2002-20116, filed in the Republic of Korea on Apr. 12, 2002. Applicant also claims benefit of Republic of Korea Patent Application No. 2002-20116 under 35 U.S.C.§.119.
The present invention relates to a fence. More particularly, the invention relates to a fence capable of adapting to any angle of inclination comprising a plurality of columns, horizontal connecting members which have more than one degree of freedom through a connecting means between a pair of columns and vertical connecting members which are connected to the horizontal connecting members.
In general, the conventional fence comprises a plurality of columns which act as a structurally supporting member, horizontal connecting members and vertical connecting members which are connected to each other. The fence is usually made of metal or plastic and is constructed on the outside of a house or building in order to protect from intrusion as well as to define a perimeter.
However, the conventional fence can not easily be constructed on a ground with a degree of inclination due to its interconnected structure between horizontal connecting members and vertical connecting members. As a result, a separate fence that fits the inclination of the ground has to be manufactured.
Korean Utility No. 201594Y discloses an assembly fence which compensates the above mentioned weakness. As shown in
The above mentioned fence is constructed by first joining the rail fixing bar 22 with a curvature section 24 with the column 11, fixing the rail fixing bar 22 to the rail 21, joining another rail fixing bar 22 with the column 11 in order to maintain a fixed angle with respect to the rail which is fixed to the column 11, connecting another rail to the column 11, fixing the pole 31 which is formed by putting a front face plate and a back face plate together on the rail 21 at regular interval in order to construct a fence.
The angle of the above fence becomes fixed when the rail 21 and column 11 are joined together. As a result, it can not be constructed on an uneven surface with an angle of inclination and also it is prone to corrosion since the linkage sections are exposed to outside.
The object of the present invention is to provide a fence which can be constructed easily on the ground irrespective of its angle of inclination and its linkage sections are completely protected from the outside exposure while having a sufficient structural strength.
a and 1b show a cross section view of the conventional fence and its installation.

The fence according to the present invention comprises: a plurality of columns each of which has a head and a supporting plate at the upper and lower end respectively; a plurality of horizontal connecting members each of which has more than one degree of freedom through a connecting means between a pair of said columns; a plurality of vertical connecting members each of which is perpendicularly connected to the horizontal connecting members at regular interval.
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As illustrated in
The column 100 comprises a main body 110, and a head which is fixed to the upper end of the main body.
The main body 110 comprises a main frame 110a which is made of metal having a supporting plate 110a-1 at the lower face, and a cover 110b which is made of plastic covering the whole exterior of the mainframe 110a.
On the internal surface of the cover 110b, a plurality of protruding ribs 110b-1 are formed as a single body and chambers 110b-2 exist at each of its four corner section in order to maintain certain amount of space between the corner sections and the mainframe 110a.
On the supporting plate 110a-1, a slit shape bolt hole is formed to be attached tightly while maintaining a clearance between the supporting plate and an anchor bolt 130, which is buried on the ground. A sealing member 110a-2 which covers the supporting plate 110a-1 is tightly attached on the outer surface of the cover 110b.
The lower face of a head 120 is constructed as identical to the shape of the cover 110b in order to be tightly attached to the upper end of the cover 110b. Also, the shape of the head is formed in such a way that no accumulation of rain could occur.
Also, the head 120 comprises a first head 120a and a second head 120b which are installed in such a way that they can either be separated or dismantled by a linking means 160.
The linking means 160 comprises a first attaching face 160a which is formed on the lower section of the first head 120a, a fixed protruding section 160b which protrudes at the center of the first attaching face 160a, a plurality of fixing pieces 160c which are constructed at the circumference of the fixed protruding section 160b, a second attaching face 160d which is formed on the upper section of the second head 120b, a supporting hole 160e which is formed at the center of said second attaching face 160d, a fixing groove 160f which is formed at the circumference of the supporting hole 160e corresponding to the fixing pieces 160c. At the one side of said fixing groove 160f, a lodging slot 160g which has a sliding face, is formed.
A horizontal connecting member 200 which is connected horizontally to the side of the column 100 through a connecting means 210 comprises a cover 220 and a frame 230 which is being inserted to inside of a cover 220. The cover 220 has ribs 220a on its internal face.
Furthermore, the connecting means 210 comprises a supporting body 210a which has a receiving space 210a-1 and a fixing plate 210b which allows omni-directional rotation through the second connecting means 210d.
The second connecting means 210d comprises a fixed ball 210d-2 which joins the supporting body with a fixing hole 210d-1 which is formed at one side of the fixing plate where the fixed ball 210a-2 can be lodged and rotated.
Alternatively, the connecting means 210 can comprise a supporting body 210a which is constructed to support the horizontal connecting member at three faces, and a fixing plate 210b which protrudes at one face of the connecting means 210 as a single body as shown in
Also, a long hole 210a-1 is formed on the supporting body 210a and a covering member 210c, which has an open hole at the outside of the connecting means that allows a swing motion of the horizontal connecting member.
The connecting means 210 comprises a supporting body 210a which has a receiving space 210a-1 and a fixing plate 210b that is connected to at one end of the connecting means 210 as a single body as shown in
The vertical connecting member 300 which is perpendicularly connected to the horizontal connecting member 200 along the longitudinal axis at regular interval.
A head 310 is fixed at the upper end of the vertical connecting member 300 and a sealing member 320 is fixed at the lower end of the vertical connecting member.
As shown in
The sealing member 320 can either be tightly attached to the internal face or external face of the lower section of the vertical connecting member 300.
The vertical connecting member 300 comprises a plastic cover 330, and a metal frame 330a which is inserted to the inside of the plastic cover 330. The metal frame 330a has ribs 330b which prevent a trembling movement. At the upper and lower ends of the vertical connecting member 300, the sealing member 350 is tightly attached.
Also, the vertical connecting member 300 and horizontal connecting member 200 are joined together by inserting a T shape attaching member through the fixing hole that penetrates the vertical connecting member 300 and horizontal connecting member 200.
At one side of the column and connecting means, which are joined together by bolts or pieces, has some more bolts (pieces) connecting section 290a to be fixed by a sealing cap 290 at one side.
Hereinafter, the effects of the present invention with the above construction will be described in detail.
As shown in
The connecting means 210 that connects between the column 100 and the horizontal connecting member 200 is protected from a direct contact with moisture by forming a bolt connecting section 290a as a single body where a joint bolt can be inserted and a sealing cap is fixed when the joint bolt is installed on the bolt connecting section 290a.
The moisture intake to the column 100 and the horizontal connecting member 200 is prevented by tightly attaching the heads 120, 310, which are formed in such a way that no accumulation of rain could occur, to the upper section of the column 100 and the horizontal connecting member 200.
Furthermore, a loose movement of the column 100 is prevented when installed vertically by a supporting plate 110a-1 which is connected to a main frame 110a as a single body. When the supporting plate is connected to an anchor bolt which is buried under the ground, the column 100 is fixed on the upper face of the ground.
On the supporting plate 110a-1, a slit shape bolt hole is formed in order to attach tightly while maintaining a clearance between the supporting plate and an anchor bolt 130 which is buried under the ground, hence, improving the work efficiency.
At this instance, the sealing member 110a-2 which covers the supporting plate 110a-1 is tightly attached on the outer surface of the cover 110b in order to prevent any intake of moisture.
The cover 110b and the main frame 110a, which is inserted to the cover, are space apart by a plurality of ribs in order to maintain the internal space dry and to allow an easy control over setting the clearance when the cover is inserted to the outside of the frame as well as preventing any loose movement.
Since the heads 120 comprise a first head 120a and a second head 120b which are joined to by a linking means 160, the shape of the fence can be changed freely by installing various types of the first head 120a on the upper face of the second head 120b.
The user can vary the external appearance by changing the first head 120a which can have various shapes. A plurality of fixing pieces 160c, which are formed around the fixed protrusion 160b, are inserted to the fixing groove 160f, which is formed around the supporting hole 160e and directly facing the fixing pieces 160c, are firmly fixed by a rotating movement.
The fixing pieces 160c are firmly supported by a lodging slot 160g after being inserted along the sliding face at one side of the fixing groove 160f. As a result, the first and second heads are tightly attached together.
The horizontal connecting member 200 which is connected to the side of the column 100 in the horizontal direction is freely movable due to the connecting means 210, hence, the fence can be easily installed on a ground with various degrees of inclination.
As shown in
At this instance, the downwards movement of the connecting means are prevented by a “” shaped supporting piece which is inserted to the plastic fixing plate 210.
Also, the up and down movement of the horizontal connecting member 200 is possible by attaching it to a supporting body 210a through a hole 210a-1 as shown in
The connecting means 210 can freely move in omni-direction around the column 100 by comprising a supporting body 210a which has a receiving spec as shown in
Also, the second connecting means 210d allows the free movement of the horizontal connecting member 200 by comprising a fixed ball 210a-2 which protrudes from the supporting body 210a and a fixing hole 210b-1 which is installed at one side of the fixing plate 210b and accepts the fixed ball 210a-2.
As shown in
Also, the decorating plate with various colors can be inserted in order to be able to change the external appearance of the fence. The decorating plate prevents exposures of bolts in order to protect them from corrosion.
When an external shock is applied to the decorating plate 340, the shock is absorbed by the attaching plate 340a which protrudes from outside of the vertical connecting member 300 when it is installed on the guide rail 330a.
The shape of the head 310 is such that the water on the upper section can freely flow downwards. The shape of the lower section is such that at one end of the vertical connecting member 300 can easily be inserted to it.
The vertical connecting member 300 comprises a frame 330a which is inserted between the cover 330 and inside of the vertical connecting member 300. It is fixed to a horizontal connecting member by a T shaped attaching member 360. Ribs are installed on the cover in order to prevent the trembling movement of the frame 330a.
The fence according to the present invention can be constructed easily on the ground irrespective of its angle of inclination and its linkage sections are completely protected from the outside exposure while having a sufficient structural strength.
Also, the shock which traveling to the fence can be absorbed therefore preventing the shock reaching the column.
The following is a detailed explanation through examples of the invention. It should be understood, however, that the detailed description and specific examples are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
