[0001] Numerous type of movable emergency signs are at present known for road, construction
site signals and the like, supplied to police forces, to armed forces, to fire brigades
and to security service employees of buildings, construction sites etc.
[0002] These signs are used to signal particular emergency situations due to anomalous traffic
or working conditions like interruptions and deviations for maintenance works road
blocks, speed limitations, presence of suspended weights, of overhead electric cables
etc.
[0003] Said signs are generally composed of a supporting stand and a rigid table, preferably
of metal, on which the desired signal is inserted with stove enamelling or in refractive
film.
[0004] Said table may be of triangular, round or square shape, depending on whether it
must signal a dangerous situation or give a prescription (order, prohibition) or an
indication, and may be applied in fixed or dismountable manner to the stand. This
may be of folding or dismountable type, with frame in forged metal or with tubular
metal frame of tripod shape, with possible lantern-holders with grill, which may
be ballasted for greater stability.
[0005] All solutions based on the movable sign concepts described above are in themselves
fairly practical and functional, but present the important problem of the considerable
bulk of the stand-signal unit. This makes it necessary to use means of transport with
very roomy luggage compartments, suitably modified to contain in orderly fashion the
equipment to be carried to the place of use. These solutions almost always have poor
stability in the presence of strong wind.
[0006] The object of the present invention is the construction of a movable emergency sign
which offers the advantage of having, in the "closed" position, very limited dimensions,
and of being easily transportable on normal motor vehicles without particular modifications
or elaborations to the luggage compartment.
[0007] This sign is essentially composed of a base from which is extracted in X shape the
pedestal, and, vertically, to the supporting plane, the signal of self-winding type
on refractive fabric with rod anchorage. This solution also makes it possible to
obtain, with respect to the signs at present known, an easier preparation for a rapid
installation on the required place and an optimal stability even with strong wind.
[0008] The characteristics of the sign constructed according to the present invention will
be evident from the following description of two of its constructive forms given,
by way of unbinding example, with reference to the enclosed drawings, in which:
fig. 1 is the perspective view of the sign with only one central supporting rod and
the signal wound;
fig. 2 is the perspective view of the same sign of figure 1 with pedestal opened in
X shape, supporting rod erect and signal wound;
fig. 3 is the front view of the same sign as figures 1 and 2 with signal wound and
anchored to the supporting rod;
fig. 4 is the front view of head A;
fig. 5 is the front view of head B with the parts of the wound signal anchored to
the supporting rod and of the small locking plate of the winding roller shaft;
fig. 6 is the front view of head B with the part of the arrangement of the upper edge
of the signal trimmed with metal in the special containing pockets;
fig. 7 is the front view of the sign with the self-winding signal unwound and fixed
to the two lateral supporting rods.
[0009] With reference to figures 1 - 3, a description follows, as unbinding example, of
the self-winding sign with a single central supporting rod. Said sign consists of
a base 1 in metallic material, generally steel, having preferably, but not exclusively,
the parallelepiped form, equipped on the two heads A and B with supporting feet 2
and suitable to contain, wound on a roller with the pins 4, the self-winding signal
3, forced to remain wound on said roller by a spring system of known type, not indicated
in the drawings.
[0010] On the free end of said signal a trimming 5 is provided con taining a metal section
which serves to maintain the signal taut in opening phase and to support a suitable
anchoring device 6.
[0011] Said device is fixed with rivets to the abovementioned trimming with section by
means of a small plate 7 and is equipped with an extraction eyelet 8.
[0012] Under the base 1 is provided, integral with same, a movable bar 9, preferably, but
not exclusively, with metal section, generally steel, equipped on the two ends with
supporting feet 10. Said bar, with sign closed, takes up a parallel position to the
abovementioned base, locked by a self-locking spring-device of known type which makes
it possible, when rotated in the plane forming with the base an X-shaped pecestal
with arms at 9 °, to keep it locked also in open position.
[0013] On one of the larger sides of said base is arranged, in central position with respect
to heads A and B, a supporting metal rod, preferably, but not exclusively, of tubular
type, of lozenge shape, with parallel sides.
[0014] When the sign is in closed position (fig. 1), said rod is arranged parallelly to
the abovementioned side of the base, locked by the device with rotating lever 12.
When the sign is in open position (figs. 2 and 3), it is arranged in vertical direction,
locked by said rotating device.
[0015] To switch from the first to the second position, slacken said rotating device, slide
it to the end of the rod, rotating it in upward direction, then refix it with said
rotating device. At this point, extract, pulling it up by means of the eyelet 8,
the self-winding signal 3, which remains locked in open position after connecting
the anchoring device 6 on the upper end of the supporting rod 11. At this point the
sign is ready to be placed for use.
[0016] In figures 4 and 5 are shown the preferred, but not exclusive, solutions for the
fixing of the pin 4 of the roller of the self-winding signal 3 on heads A and B of
the base 1. After positioning said roller in such a way that the trimming with metal
section 5 faces, as indicated in the figure, the interior of said base, insert the
first pin 4 in the groove 14 of head B. Then fix said second pin applying, for example,
a small plate 15 equipped with through-hole calibrated for the pin, which may be
fixed to the abovementioned heads with the screws 19.
[0017] Figure 6 shows some details relating to the methods of positioning, along one side
of the base, the free end of the signal comprising the trimming with section 5, when
the sign is in closed position. At the two heads A and B, on the side of the base
opposite that on which the supporting rod 11 is arranged, two pockets 13 are provided
in which the abovementioned free end of the signal may be inserted pulling the eyelet
8 downwards.
[0018] As may be seen, the structure described above refers to a self-winding emergency
sign which provides the indicator signal on only one side, the other side being affected
by the central supporting rod and therefore not fully utilizable to carry the signal.
[0019] A variant of the abovementioned sign consists of a second self-winding sign, shown,
as unbinding example, in figure 7. Said second sisng provides two lateral supporting
rods 21 and may have an indicator signal 3 with the indication shown on sides.
[0020] Said rods are positioned near heads A and B and are preferably, but not exclusively,
in extractable metal tubular section. They are locked in horizontal or vertical position
by the devices with rotating lever 22.
[0021] At the two ends of the trimming with metal section 5 are arranged, in suitable position,
two anchoring devices 16 with relevant extraction eyelets 18, which make it possible
to fix the unwound signal on the corresponding supporting rods 21.
[0022] For the other parts the references shown on the example of sign with a single central
rod apply.
[0023] The province of the present patent is not excaped changing the aesthetic and/or constructive
characteristics of the various elements which compose the two proposed signs, e.g.

of the rods, the anchoring devices of the sig nal, the fixing devices of the pins
