[0001] The present invention relates to the fencing field, namely fence of plastic tubes,
comprising the fence blocks placed and fastened between vertical hollow poles and
may be used as decorative and/or security fence.
[0002] For a long time fencing installations for strength and aesthetics used traditional
materials such as wood, metal (
DE10239983A1,
US4722514A). Currently, for practical reasons, ecology and better performance qualities, increasingly
fences are made of plastic, using recycled plastic household waste.
[0003] It is known a decorative security fence comprising vertical poles, between which
blocs of security fence are positioned and fastened. Each block consists of interconnected
horizontal and vertical plastic tubes. The fence block has at least two horizontal
plastic tube elements with galvanized wire inside. The ends of the galvanized wire
are attached to the vertical poles and covered with the lengthwise cut plastic tube,
which has holes, spaced at the predetermined intervals, for vertical plastic tubes
of the said block to be inserted through and properly fixed. The said galvanized wire
in the lower horizontal element is inserted through the holess, located on the vertical
plastic tubes. The said galvanized wire, stretched between the vertical plastic tubes,
makes a wireframe of the fence block, which withstands mechanical loads on the fence
and is used to tighten the vertical plastic tubes. See
LT patent No: 5684.
[0004] The drawback of the known decorative security fence is that metal wire is used to
transmit all the loads to the poles holding the fence block. Metal wire is susceptible
to moisture and corrodes quickly, while the lengthwise cut horizontal tubes perform
only a decorative function, and do not carry mechanical loads. When the decorative
elements of the security fence get worn, or if there is a need to replace them due
to the wire inserted through the vertical tubes, it is necessary to disassemble the
entire fence block. Document
US 2009152524 discloses a plastic fence which comprises the features of the preamble of the independent
claim 1.
[0005] The invention aims to prolong the operational life of the fence, to simplify its
assembly process as well as operational service, and to expand the applicability of
the fence.
[0006] This is achieved by the fence of plastic tubes according to claim 1.
[0007] The fence of plastic tubes proposed by this invention, consisting of plastic tubes
that are dismountable interconnected, can be used for protection against intrusion,
for livestock pens, to fence playgrounds and other places. The fence is easy to assemble,
outwardly it is very similar to a metal fence, and therefore it can be easily combined
with the latter. In choosing tubes for the fence block, each user based on his/her
preferences can easily change the height, length or color of the fence block, while
the worn out vertical tubes of the fence block can easily be replaced with the new
ones.
[0008] The proposed fence of plastic tubes has no metal parts susceptible to moisture. Tubes
of different diameters and different colors, produced from recycled plastic waste,
can be used for the construction of the fence. The tubular fence is not heavy; to
construct such a fence less plastic is required.
[0009] The fence block consist of plastic tubes without end caps or other sharp protruding
fence elements that may pose serious health risks, for instance, for children climbing
over the fence.
[0010] For livestock protection, the fence marking can be achieved by replacing some vertical
tubes by tubes of a different color. An electric fence installation for control of
animals or alarm system detectors can be installed on the upper part of the vertical
tubes.
[0011] Since the fence of plastic tubes consists only of electrically non-conductive elements,
the electrical wiring, lighting, sensors or other electrical or electronic equipment
can be installed within the electrically non-conductive plastic tubes.
[0012] The details of the invention are provided in the figure, which shows the vertical
section of the fence.
[0013] The fence of plastic tubes comprises the fence block, composed of two horizontal
plastic tubes 1, which are interconnected in a way that is easy to disassemble with
the vertical plastic tubes 2 inserted through them. The horizontal plastic tubes 1
of the said fence block has transverse holes, for inserting through the vertical plastic
tubes 2, where the diameter and shape of the said holes on the horizontal tubes 1,
as well as the diameter and shape of the vertical tubes 2 that get inserted into the
said holes, is pre-selected and shaped in such a way as to ensure stable connection
that is easy to disassemble. For example, the oval shaped holes are made on the horizontal
plastic tubes 1, while the diameter of the vertical tubes 2 is chosen in such a way
that by pressing the ends of the said tubes 2, the vertical tube 2 would easily fit
into the oval shaped hole, and, after inserting it through the oval shaped hole, it
would be tightly pressed.
[0014] The fence block is placed between the two bearing vertical hollow plastic poles 3
and it is fastened to them by inserting the ends of the horizontal tubes 1 of the
fence block through the holes made at the appropriate height on the poles 3. The ends
of the plastic horizontal tubes 1 of the fence block, inserted into the poles 3, inside
have infused meshes (not shown in the Figure). The ends of the inserted horizontal
tubes 1 are attached to the vertical poles 3 inside them, by piercing the ends of
the inserted tubes 1 with the pins 4.
[0015] The proposed fence of plastic tubes is mounted in the following way. The horizontal
hollow tubes 1 of the fence block are cut to match the predefined length of the fence
block. The ends of the tubes 1 are reinforced by infusing the metal mesh inside of
the tube.
[0016] According to the height and the design of the fence, transverse holes of the appropriate
shape are made on the horizontal tubes 1 of the fence block for inserting the vertical
tubes 2 of the fence block, for example, the oval shaped holes are made on the horizontal
tubes (1).
[0017] The vertical tubes 2 of the fence block are cut and accordingly prepared in such
a way, that it is easy to insert them through the holes made on the horizontal tubes
1, and the connection between the horizontal tubes 1 and vertical tubes 2 is sufficiently
strong. For example, ends of vertical tube 2 are pressed to match the oval shaped
holes made on the horizontal tubes 1 of the fence block such, that the pressed ends
could easily fit through the corresponding oval holes, where after inserting it through,
the vertical tubes 2 would be tightly compressed. In such a way the tubes 2 are inserted
through the holes made on the horizontal tubes 1.
[0018] The plastic hollow vertical poles are plastic tube poles 3, which are cut to match
the desired height of the fence. At the predetermined height, the holes are drilled
through the plastic tube poles 3 for fastening the horizontal tubes 1 of the fence
block. According to the predetermined fence installation project, the plastic tube
poles 3 are concreted into the ground.
[0019] The horizontal tubes 1 of the fence block are inserted into the holes of the plastic
tube poles 3, made to fasten the fence block, and, after tightening the fence block
in the position set by the project, they are fastened inside the tube pole 3 by piercing
the ends of the horizontal tubes 1 with the pins 4.
