[0001] The present invention refers to an interconnection device for fence elements. In
particular, the invention stems from the need to simplify the procedures for the erection
of fences and/or space delimitations, typically of a provisional type. Let us consider,
e.g., situations like those that may be found in building or road yards.
[0002] Arranging a provisional and temporary fence in order to delimit the work area and
prevent the fortuitous and/or accidental entrance into the yard by unauthorized persons
is typical of said situations.
[0003] It is also evident that there may be several other occasions in which the installation
of a light-weight temporary fence is necessary. Hence, it is understood that the present
invention should not be construed as limited to the specific application that will
hereinafter be described purely by way of example.
[0004] Therefore, making reference to a yard's work area, it may be frequently seen how
it is often fenced by means of a fence made by a row of posts, typically metal rods
driven into the ground, to which it is coupled a netting that may be metallic or preferably
of a plastics material.
[0005] The problems related to this type of installation and faced by the present invention
are essentially linked to the modes of fastening the netting to the posts. In fact,
in such installations, it is customary to fasten the netting to the posts by means
of strings and/or pieces of wire, arranged on various points of each post in order
to satisfactorily secure the netting to the post itself. Finally, onto the top of
the posts, which are often made by iron rods, mushroom-shaped protection elements
are placed to prevent somebody from getting injured by accidentally knocking against
a post.
[0006] However, evidently such an installation procedure is particularly toilsome. In fact,
those in charge of such a job should fasten the netting with wire, then they should
get hold of pieces of wire to be used with various tools (pliers, wire cutters or
other). Moreover, also in order to remove the fence, it will be necessary to remove
all wire ties, always making use of suitable tools. Lastly, the presence of said projecting
wire pieces, scattered substantially along the whole stretch of the protective netting,
constitutes also a cause of danger of wounds and/or injuries to persons and/or things
accidentally coming into contact therewith. In that sense, it should be considered
that, obviously, such fences are often used on public places (roads or other) where
they are easily accessible even by unauthorized persons.
[0007] Hence, object of the present invention is to solve said problems, by providing an
interconnection device for elements of a fence as defined in the independent claim
1.
[0008] Secondary features of the present invention are defined in the corresponding dependent
claims.
[0009] The present invention, by overcoming the mentioned problems of the prior art, entails
several evident advantages.
[0010] In particular, it completely eliminates the need to use strings and/or pieces of
wire in order to fasten the protective netting to the supporting posts. Hence, this
entails a higher safety of the installation and more rapid and effective erection/disassembly
modes, not requiring the use of any tool.
[0011] Moreover, the present invention integrates different functions in a single system,
by comprising elements and devices concomitantly acting both as elements for fastening
fence portions and as protection elements.
[0012] Further advantages, as well as the features and the operation modes of the present
invention, will be made apparent from the following detailed description of preferred

[0013] The present invention will hereinafter be described in detail making reference to
the above-indicated figures.
[0014] In particular, figure 1 refers to a first embodiment of the device according to the
present invention.
[0015] A fence is generally comprised of a plurality of fence elements interconnected thereamong
so as to attain a predetermined operative configuration.
[0016] A device 1 comprises first of all a portion 2 for anchoring the device to a first
fence element and a portion 3 for coupling to the device of a second fence element.
[0017] Moreover, the coupling portion 3 comprises a hook-like element 4 shaped so as to
be apt to receive said second fence element.
[0018] In order to better describe said first embodiment, reference will be made to the
exemplary case of a fence, typical of road yards, made by means of first fence elements
that are comprised of vertical supporting posts 10 driven into the ground, typically
iron rods, to which it is anchored a second fence element that is a protective netting
11, typically of plastics material. Such a fence is exemplarily illustrated in figures
6A and 6B.
[0019] According to said embodiment, the anchoring portion 2 comprises a substantially cylindrical
hollow body 5. In the example depicted, said body is shown of circular section, yet
it is evident that the same could have a section compatible with that of the post,
in case a supporting post having a non-circular section were used.
[0020] Advantageously, the hollow body 5 has a first bottom end 6 open for the insertion
on a free end of said supporting post 10, and a second closed top end 7. Such a mode
can be seen in figure 7.
[0021] Preferably, at the closed end 7, the device further comprises a protection element
8, preventing injuries to persons and/or things accidentally knocking against the
fence.
[0022] Preferably, the protection element 8, is substantially mushroom-shaped and it has
a side shaped so as to leave free access to the coupling portion 3, as it will be
better described hereinafter.
[0023] One or more inward-projecting longitudinal ribs 9 are present in the internal portion
of the hollow body 5.
[0024] According to the preferred embodiment, the cylindrical body 5 internally has three
longitudinal ribs 9, inward-projecting and arranged at 120° the one with respect to
the other.
[0025] These ribs have a variable thickness lengthwise. In particular, they are thicker
at the closed end of the device than at the open end thereof, so as to create an inlet
raiser at the open end of the cylindrical body itself.
[0026] Thus, as it is evident in figure 7, the device could be used with iron rods within
a given diameter range, ensuring anyhow a good interference with the metal and thereby
preventing an accidental unthreading of the former.
[0027] Always according to said embodiment, the hook-like element 4 is special-purpose for
supporting a protective netting. In particular, the hook-like element 4 comprises
one or more tongues 20 for holding the netting 11.
[0028] Each of the tongues 20 has a free end 21 and an elongate shape apt to hold the netting
when the latter is coupled, as it is shown in figure 7.
[0029] Advantageously, the hook-like element 4 further comprises a detent 22, apt to interfere
with the netting when the latter is coupled, in order to prevent the involuntary uncoupling
thereof.
[0030] On the other hand, since the device, and particularly the hook-like element is made
of a sufficiently elastic material, the voluntary uncoupling of the netting, e.g.
when it has to be removed, is made especially easier. In fact, it will suffice to
exert a slight force on the tongues 21, in the opening sense thereof, to simply unthread
the netting, preventing the interference with the detent.
[0031] According to the preferred embodiment, the hook-like element 4 comprises two holding
tongues 20, arranged parallelly therebetween, and a detent 22 arranged between said
two tongues.
[0032] Figures 4, 5, and 5A refer to a second embodiment of the device according to the
present invention.
[0033] According to said embodiment, the device 30 differs from the one described hereto
in the anchoring portion 31, whereas it comprises a coupling portion 3, in all identical
to that described at the first embodiment, whose description therefore will not be
repeated.
[0034] The anchoring portion 31 comprises a band-like element 32, having a substantially
open C-shaped section, compatible with that of the supporting post. In the exemplary
case, in which reference continues to be made to an iron rod, the section will be
round C-shaped, such as to be fixedly inserted in a middle position along the supporting
post, as it is shown by way of example in figures 6A and 6B.
[0035] Said second embodiment could advantageously be used in conjunction to the first one,
in order to complete a system for anchoring a protective netting to the supporting
rods thereof, with all of the advantages highlighted in the foregoing.
[0036] The band-like element 32 will preferably be made of a material having a certain degree
of elasticity and shaped so as to have a preferential inlet region 33 on the rod,
such that once the latter is inserted, the band partially embraces the rod itself,
the device being thereby satisfactorily anchored onto the supporting post.
[0037] Figures 8, 9 and 10, refer instead to further embodiments of the present invention.
[0038] In particular, a third embodiment is that of a device 40 shown in figure 8. In this
case, the anchoring portion 41 is in all alike that already described in connection
with the first embodiment, i.e. of the type apt to be anchored at a top end of a vertical
supporting post. Hence, also this embodiment could advantageously have all of the
hereto-described features, and also a protection element 42.
[0039] On the contrary, the hook-like element of said third embodiment was expressly studied
and designed for those cases in which the second fence element to be interconnected
is not a protective netting, but rather a tubular element 50, e.g. a second iron rod
to be arranged horizontally or in a skew position with respect to the vertical supporting
post 10.
[0040] According to said embodiment, the hook-like element 43 of the device 41 comprises
a region 44 for housing the rod 50. Preferably, such a region will be U-shaped, with
the open region of a smaller width with respect to the rod diameter, so as to allow
a partial fixing of the rod when the latter is coupled.
[0041] The hook-like element 43 is set, with respect to the anchoring portion, so as to
support said second element according to a predetermined operative configuration;
in particular, it could be set horizontally, at 90° with respect to the anchoring
portion, or set at about 45° with respect thereto, as it can be seen in figures 11
and 12.
[0042] Analogously to what has hereto been described in connection with the preceding embodiments,
it is possible to provide a fourth embodiment, illustrated in figure 9.
[0043] In this case, a device 60 is made so as to have a hook-like element 63 of the hereto-described
type, apt to support a tubular element 50. On the other hand, the device 60 comprises
instead an anchoring portion 61, in all alike that described with reference to the
second embodiment, hence of a type apt to be anchored at a middle position of a vertical
supporting post 10.
[0044] Therefore, the devices 40 and 60, described last, could advantageously be used in
conjunction, as illustrated in figure 10.
[0045] Finally, figure 13 refers instead to a fifth embodiment of a device according to
the present invention.
[0046] In that case, a device 70 is specifically contrived for those instances in which
the fence comprises horizontal supporting elements 69 used in conjunction with vertical
supporting posts 100 apt to support them. Such a fence is exemplarily shown in figure
14, where the vertical posts are iron rods having a U-shaped portion for supporting
wooden boards arranged transversally between successive posts.
[0047] In that case, the device 70 according to the present invention has an anchoring portion
71 comprising a band-like element 72, having a substantially open C-shaped section,
compatible with that of the horizontal supporting element, and such as to be fixedly
inserted in a middle position along said horizontal supporting element.
[0048] The hook-like element 4 of said embodiment is preferably that described in connection
with the first embodiment, i.e., such as to support a protective netting 11.
[0049] Of course, it is understood that the different embodiments described hereto could
advantageously be used according to different combinations thereof, depending on the
desired fence configuration. For this purpose, the present invention also refers to
a kit for the assembling of provisional fences, comprising two or more of the devices
according to one or more of the embodiments described.
[0050] The present invention has hereto been described according to preferred embodiments
