[0001] Equipment or devices for indicating work in progress (and/or danger or for any other
exigency), can be of various types, more or less practical in positioning in places
where they are needed, and for later being removed to be set aside for use at a later
time.
[0002] This can occur on a road, near building sites, in hospital corridors during cleaning,
to prevent people from transiting, or for warning those who happen by of the existence
of a particular situation that is inconvenient, or dangerous, or of a general obstacle,
or for pointing out any precautions to be taken at that particular time and at that
particular place.
[0003] Well known in this regard are the double-sided signs composed of some flat elements
that are hinged together, which are opened when needed like a book on its edges, so
as to constitute a type of easel, and when they are no longer needed are closed and
taken away.
[0004] From now on a single flat element here will be called a "wing".
[0005] Said signs have openings near the top so they can be gripped.
[0006] In the space above the openings there is a through hole that is generally used to
hang the sign on a trolley, for example the multi-purpose type for cleaning, like
the one used in hospital corridors, which is equipped with a special overhanging pin
to be inserted.
[0007] We should bear in mind that said signs do not have any appendages that come out from
the outer surfaces because they would hinder the signs being stacked on top of each
other for storage or transportation.
[0008] One of the problems of the double-faced signs that have been considered, in the event
that the above-mentioned signs need to be taken from the trolleys which transport
them to be positioned where needed, usually in places with heavy pedestrian traffic
to indicate some danger, is the lack of practicality and speed for the operator who
has to use them, and a similar problem exists for the operator when said signs have
to be loaded again onto said trolleys.
[0009] It is clear that said insertion manoeuvre means the operator has to pay extra attention,
with a loss of time that creates some inconvenience in work like that of cleaning,
where the employment, recuperation and returning to their proper places of the various
equipment takes place frequently and this handling occurs almost automatically without
requiring excessive physical effort and very quickly.
[0010] The purpose of this patent is to enhance this firmly established procedure of picking
up the signs and putting them back.
[0011] This is achieved by adopting signs with a plate entirely hinged along the top edge
of an opening, which when not used is hung inside the opening and which, when a hand
is put in the opening to grip the sign, said plate rotates towards the inside; while
because of its functionality said plate is made to rotate in such a way that it protrudes
from the outer surface of the wing on which it is hinged so as to constitute a suitably
angled appendage.
[0012] To take off the sign the operator puts his hand in the opening and lifts the sign
keeping it suspended. Likewise, to put the sign back the operator puts his hand in
the opening, with no special care required, and puts it back hanging it on a rim,
or a trolley support or on the rims of any accessories carried by the trolley.
[0013] To hang more than one sign, the trolley has to be fitted with rims or supports (like
horizontally positioned tubes) taking into account that the plate has its free end
curved downwards so as to get a better grip corresponding to a type of anchorage.
[0014] What has just been described becomes clear from an examination of the attached diagrams.
[0015] Fig. 1 is a frontal view of a sign currently on the market. We can see the hinging,
the opening for gripping and the hole above for hanging the sign up.
[0016] Fig. 2 shows the sign from fig. 1 with the two wings against each other.
[0017] Fig. 3 is a front view of the sign shown in fig. 1, in an open position.
[0018] Fig. 4 shows the sign of fig. 3 with the wings open wide so that it makes an easel
shape.
[0019] Fig. 5 shows the sign made according to this patent with the wings hinged at the
top and closed. We can see that at the top of the opening of one of the wings a plate
with a curved end is hinged, protruding outwards. In said position the plate can be
applied to any available horizontal rim or profile to support the sign. It should
be specified that the plate shown protruding, when left free, its natural position
is that of hanging.
[0020] Fig. 6 shows the sign from fig. 5 viewed from the side and from the front.
[0021] Fig. 7 shows the sign supported with the hand of an operator inserted into the opening.
[0022] Fig. 8 shows the sign of fig. 7 opened up, where the opening is restricted by two
blocking appendages on the hinge connections. We can see again that the plate that
is hinged at the top of one of the openings is in its natural vertically hanging position.
[0023] Fig. 9 shows that using a jointed plate it is possible to hang a sign to another
that is already hanging up.
[0024] Fig. 10 is a close-up of the top part of the two signs put together of fig. 9.
[0025] Fig. 11 shows the internal part of a wing of a sign (which in the case in question
does not have the opening at the base that constitutes the support legs) where we
can see how the hinge engages the upper rim of the opening with the plate.
[0026] Fig. 12 shows the outline of the articulated plate. We can see the external shape
above the housing for the hinging, which rests on a special striker plate of the opening
that limits its free rotation upwards.
[0027] Fig. 13 is a flatwise view of the inside part of the plate of fig. 12. We can see
the configuration of the housings for connecting with the pin carried by the sign.
[0028] Fig. 14 shows the inside of the plate viewed from above.
[0029] It is well known that signs on the market are composed of two wings 1, 5 hinged 2
together at the top, which when not being used rest next to each other and when they
need to be used are separated at the base so as to make a kind of easel. The degree
of opening is limited by special strikers 11 placed at the hinges 2 with which one
of the wings is equipped.
[0030] Towards the top, both the wings, which are practically mirror images of each other,
have two openings that allow the operator to grip them.
[0031] In the space above the openings 3 the wings have a hole that is used to connect them
to a wall, for example, of a multi-purpose trolley for cleaning that has an protruding
peg.
[0032] Obviously the insertion operation has to be done carefully, with correct centring.
If there are several signs, then the peg has to be long enough or else there have
to be several pegs.
[0033] Existing signs, similar to the signs made according to this patent, virtually have
a corresponding configuration regarding the wings 1, 5 as well as the hinging 2 at
the top, and also with regard to strikers 11 that limit the opening at the bottom,
and also the openings 3 and the suspension holes 4.
[0034] In the signs made in accordance with the patent, the two wings 6, 7 both have apertures
9 so that the operator can grip them.
[0035] One of the wings 8 has, on the upper inside part of the opening 9, a special arrangement
of pins 12 to which the housing 14 of a special plate 10 is connected.
[0036] Said plate 10 is made in such a way that when not being used it remains in its natural
hanging state.
[0037] For the operator to take the sign 6, 7 the plate 10 rotates inwards with a horizontal
disposition on the upper part of the hole of the apertures 9.
[0038] The function of the plate 10 is to make it rotate towards the outside of the wing
8 on which it is hinged reaching the locking position 16, 16.
[0039] In said position, because the free end 13 is curved, the plate 10 constitutes an
effective protruding appendage capable of engaging special rims 17 and supports for
supporting the entire sign 7, 8.
[0040] The plate 10 in said position of protruding appendage is also capable of engaging
the lower rim of an opening of another sign placed right in front of it.
[0041] This type of connection can be used in succession for several signs.
[0042] In said manner, to an initial sign 7, 8 supported by a fixed or mobile load-bearing
structure 17 you can hang a succession of other signs 7, 8.
[0043] What has just been explained is the originality of the invention, as well as its
high degree of inventiveness that revolutionises an already well-established system
for hanging the sign, which invention makes a mobile protruding appendage just to
realise the suspension of the sign without therefore increasing the dimensions when
putting several signs on top of each other.
1. Easel-shaped two-sided work in progress and warning sign with improved bundling, characterized by the fact that the wing elements (8) of the sign (7) have a plate (10) which is hinged
(12, 14) along the top edge of its opening (9) used for gripping.
2. Easel-shaped two-sided work in progress and warning sign with improved bundling according
to claim 1, characterised by the fact that the configuration of the pin (12) in line with the top edge of the
opening (9) of the wing element (8) is such that it allows the plate hinged to it
to hang in its normal position when the sign is not being used, and to be rotated
inwards when the sign (7, 8) is being gripped and to be rotated towards the outside
of the wing (8) onto which it is hinged, becoming slightly protruding towards the
outside in order to be put above the edge or a support /17) of a load-bearing structure
so that the sign itself (7, 8) is supported.
3. Easel-shaped two-sided work in progress and warning sign with improved bundlingaccording
to claim 1, characterised by the fact that the plate (10), when it is protruding outside of the opening (9) of
the wing (8) to which it is hinged (12, 14) is kept at an acute angle with the surface
of the wing (8) beneath, so that in addition to supporting the sign (7, 8) it keeps
it against the structure (17) that supports it.
4. Easel-shaped two-sided work in progress and warning sign with improved bundling according
to one or more of the previous claims, characterised by the fact that a successive sign (7, 8), with respect to a previous sign (7, 8) already
hanging (17) using its plate (10) positioned on the outside of its opening (9) of
the wing (8) to which it is hinged (12, 14), is hung on the lower edge of the opening
(9) of the wing (7) of the sign (7, 8), next to the one before it.
5. Easel-shaped two-sided work in progress and warning sign with improved bundling according
to one or more of the previous claims, characterised by the fact that the plate (10) has an end (13) that is curved downwards in order to
increase the grip of the suspension of the sign (7, 8) with anchorage functions.
