[0001] De invention relates to a device with vertically moveable closure poles which serve
to make certain parking places or road parts for vehicles, such as motorcars, inaccessible.
To this end poles are used, which can descend in a vertical casing that is present
in the ground.
Making a closure of a ground with a number of poles is complicated and expensive.
[0002] The object of the invention is removing this objection.
[0003] According to the invention this object is reached, in that the poles are mutually
connected underground by horizontal casings, in which casings the operating members
for the poles are housed. Preferably the poles are activated hydraulically or otherwise,
such as mechanically.
[0004] By means of flanges the horizontal casings of the connection channels are connected
mutually and with the pit for the hydraulic facilities.
[0005] The invention provides a closure system with which with as much as possible standard
elements, which can be coupled by means of flanges or otherwise, such as by welding
or screwing, variable embodiments are possible.
[0006] By the facility for removing leaking water and the water tight flange connections
the use is possible in places with a high ground water level.
[0007] By the application of the horizontal underground casings ducts and electrical connections
are protected. The mutual distance of the closure poles is well guaranteed and the
underground casings offer extra stability.
[0008] The invention is now elucidated referring to a drawing.
Fig. 1 shows a cross section of four poles with a pit.
Fig. 2 shows the poles in the extended position.
Fig. 3 shows the guiding of the pole with the connection to a cylinder rod.
[0009] Fig. 1 shows the poles indicated with (1). The poles (1) are vertically moveable
in casing (2). The casings (2) are connected by horizontal casings (3), which are
watertight connected mutually or with a pit (4). The casing (2) together with the
horizontal casing (3) forms a standard element which can at will be connected with
other standard elements. The pit (4) extends into the street part (5) that lies into
the road surface (6), or in the ground level lying nearby. In the pit (4) a hydraulic
unit is present, comprising a pump (7) having an electrical engine (8) and provided
with control slides for the hydraulic operation of the poles (1).
[0010] In the pit (4) a provision is present for removing leaking water (9) which either
comprises an electrical pump or a connection to the sewage system.
[0011] Fig. 2 shows the cylinder (10) having a cylinder rod (11). The poles (1) are guided
by guiding strips (12). With interrupted lines (13) the position of the pole (1) in
the sunken position is shown.
[0012] Fig. 3 shows details of the pole structure. The cylinder rod (11) is provided with
a cross piece (14) having cut holes (15). In these hole (15) fit dowels (16). In the
pole (1) reinforcement pieces (17) are welded, which are provided with radial holes
in which the heads of the hard steel dowels (16) fit. The assembly is covered by a
reflecting plate (19). By removing the dowels (16) the pole (1) can be drawn from
the casing (2). This system forms a security against the unauthorized dissembling
of the pole.
[0013] The poles (1) can be activated by a remote control (infrared), several types of cards,
mobile telephone, coin operation etc.
[0014] The poles (1) can be made with a square, rectangular or round cross section. Also
the weight of the structure can be adapted to the object, such as anti-burglary or
anti-ramming burglary pole.
[0015] Also there are variations possible having lightning or reflection.
[0016] The level of the poles (1, 2) can be set to adapt for unevenness in the level of
the ground, by adaptation of the connection cases (3). This adaptation is possible
for instance with (not shown) slot holes for the connection bolts in the flanges.
