Description
[0001] The invention refers to a student's protection board from
emergencies such as gunshots, earthquakes, explosions, fire, etc.,
which was invented to be used as a protection room and in order to
prevent fatal accidents in places where children are hosted like
schools, private language schools etc.
[0002] The present industrial application relates to a flexible
folding student's protection board that can be converted quickly
and easily into a shielded protection room against portable weapons
and ammunition of any type and caliber and also to a hermitically
closed protection space that prevents emergencies such as natural
hazards i.e. earthquakes, fires etc., and cases of targeted
violence such as explosives and chemical-biological substances.
[0003] Unfair attacks on schools aimed at children by organized or
individual terrorist groups that aim to provoke the international
community and to force difficult situations are a frequent
phenomenon. There is also high frequency of unforeseen events such
as earthquakes, fires etc. that cause panic to children and adults
even in cases that the treatment of these situations has been
foreseen.
[0004] From February 1996 up to October 2015 there have been over
60 incidents of mass killings in schools in America and around the
world, with a very large number of deaths. Since then huge sums of
money have been spent by state agencies to take preventative
measures and to record internal prevention regulations and treat
those emergencies which in the end prove to be insufficient.
[0005] The schools should be safe places for teaching and learning,
without phenomena of crime and violence. Each occurrence of crime
or violence at school not only affects the people involved, but it
may disrupt the educational process and affect bystanders, school
and the surrounding community. The school safety issues have grown
exponentially in recent decades, as events that have occurred in
recent years have activated people responsible for the development
of more effective systems to protect the safety of students and
staff.
[0006] The use and application of preventive-safety measures
against armed attacks, such as increasing the number of guards, use
of bulletproof windows and the installation of armored doors,
controlled entry points with metal detectors, the use of CCTV
cameras, etc. have been criticized that apart from their failure,
they pose a prison environment image and not a learning
environment. It has been reported by many school counselors that
the physical presence of guards around the school building and the
multi-view monitoring systems suggest a fake security environment
of doubtless quality and reliability.
[0007] Panic rooms or secure rooms have also become a popular trend
nowadays in order to provide extremely secure locations inside
buildings where the people under threat can subside. However, they
constitute permanent structures of high volume and high cost and
their construction must be foreseen before the fmal delivery of the
building. The US 2014/0259976 A1 describes an alternative method of
making a secure shelter which can be installed inside the building,
but whose side surfaces and the roof consists of a series of
sliding panels. Thus the construction of US 2014/0259976 A1 has the
drawback of a non-stable and non-durable construction, providing
dubious protection against threats, in contrast to the present
invention consisting of single robust surfaces coated with the
polymer sealant material.
[0008] The potential consequences of an incident with mass
casualties in schools can be mitigated by implementing a
comprehensive plan of emergency management strategy which will not
be limited to preventive measures but will mainly focus on
repressive measures. The present invention aims to create a
flexible students' protection board that is converted quickly and
easily into a shielded protection room against portable weapons and
ammunition of any type and caliber and also into a closed
protection room that prevents the emergencies such as natural
hazards i.e. earthquakes, fires etc., which can be used as the
ultimate repressive means with maximum user safety, as well as
covering the drawbacks of other systems.
[0009] One of the major features of the invention is the creation
of a shielded room of suitable dimensions which comprises the
necessary mechanisms of motion, connection and fixing so that it is
not damaged on complete folding and it maintains its shape; it is
enhanced, resistant, reusable.
[0010] According to the present invention, the above mentioned
objects, and many more which will be better understood hereinafter,
are achieved by the protection school board that in full extension
is of parallelepiped shape and is formed by the absolute contact of
folding robust surfaces, of high hardness steel metal layer (12)
which on their inner surface have a special compact layer of
insulating elastomer material (13) while their edges (24) are
coated with polymeric sealant material.
[0011] The student protection school board from emergencies: [0012]
i. A main mobile outer frame of rectangular cross section (1) which
constitutes the front surface of the room, with shape colored of
dye blackboard (2), which bears: [0013] special drive bearings (3)
to facilitate the movement [0014] protective thermoplastic
elastomer bar (4) for accidents prevention during the stay of
students [0015] optionally film light-emitting diodes (5) for
signaling of protection school board [0016] ii. A main fixed frame
of rectangular cross section (6) which constitutes the rear surface
of the room, mounted on the wall of the classroom, which bears
internally: [0017] at least two screw shaft linear drive mechanisms
(7) [0018] a hybrid propulsion motor (10) and [0019] bottles of
compressed oxygen (11) [0020] iii. Two equally sized rectangular
folding surfaces (15) which constitute the side surfaces of the
room. [0021] iv. Two equally sized rectangular folding surfaces
(16) which constitute the upper surface of the room and bears
internally: [0022] safety lights (17) with power batteries for
backup power supply and [0023] oxygen masks (18) [0024] v. At least
two hydraulic compensator cylinders (30) [0025] vi. An entry/exit
door (19) adapted on one of the two equal-sized rectangular folding
surfaces (15) forming the side surfaces of the room [0026] vii.
External unit with pushbutton star/stop (21) for setting in
operation [0027] viii. Electro pneumatic operation system including
the hybrid propulsion motor (10) and bottles of compressed oxygen
(11) [0028] ix. Manual operation mechanism with pressure lever (22)
[0029] x. Sound information system (23)
[0030] Specifically, the present invention aims to present the
manufacture and method of implementation of a students' protection
board from emergencies, in which the following are achieved:
a) preservation of all properties-benefits of a shielded permanent
shelter-room providing effective protection even in case of
earthquake, fire, chemicals etc. b) fast and totally successful
protection of children and staff without leaving unexploited
crucial seconds after the occurrence of incidents c) creation of a
friendly environment that conveys security and suppresses panic
situations in the event of emergencies d) insurance of the
necessary residence time in a safe place until the competent
authorities arrive.
[0031] A students' protection board from emergencies has many
advantages, according to the present invention.
[0032] Since the present invention relates to a folding
construction, its assembly is simple in relation to its surprising
results. The construction of small thickness makes the present
invention easy to use, because its volume enables the installation
and the operation of the invention in any desired site and point.
It can be configured in all shapes and dimensions depending on its
application and all the requirements to be met. Similarly, the
outer surface has the look of a blackboard (2) makes it fully
functional and perfectly harmonious in the classroom.
[0033] The choice of the material composition of the folding robust
surfaces, without being limited to these, produce the best possible
result related to the protection against gunshots using the
ballistic and non-flammable high hardness steel metal layer (12)
and from incidents of fire since the layer of insulating elastomer
material (13) does not allow transmission of heat inside.
[0034] Also the fact that the present invention relates to a
construction consisting of single robust surfaces enhanced with
metal plates (14) makes it a room of high resistance and tightness
even in cases of earthquakes, which is not achieved by sliding
panels and other similar devices.
[0035] The desired results and the safe stay in the student's
protection board are achieved by a simple construction which
provides thermal insulation, sealing and durability even in
ordinary chemical effects (inhalation of hazardous substances,
chemicals, fumes, etc.), even protecting from biological risks,
since it is equipped with oxygen masks (18) while the inner edges
(24) of the single robust surfaces are coated with a polymeric
sealing material.
[0036] Having achieved the best and fastest way of unfolding and
redeployment of an apparently simple blackboard (2) into a closed
protection room in just a few seconds, the students' protection
board, according to the present invention, directly and easily
protects the user from gunshots and its health effects as well as
death or injury.
[0037] Also the design specifications of the students' protection
board completely comply with safety rules as it bears a protective
thermoplastic elastomer bar (4) in order to avoid accidents during
the stay of students. It also bears a film light emitting diodes
(5) for signaling the students' protection board in the start of
the folding. Finally, the automatic sound information with an alarm
notification and recorded instructions complete the measures for
additional-maximum safe use.
[0038] The fact that the students' protection board is equipped
with main and backup power supply system and with a pneumatic
operation system, make the system a hybrid power system since it
uses more than one power production method to cover the required
energy with constant voltage. This will minimize the risk of power
failure so that its operation depends at the least bit on the
changing of external factors. In case of power supply failure of
the above mentioned systems, a manual operation mechanism with
pressure lever (22) is installed.
[0039] Its ergonomic construction in combination with the discreet
presence in the room, create a healthy-friendly environment that
does not look like security fort, which favors the psychology of
both children who do not feel trapped and monitored at the space of
teaching and the psychology of the staff as they are able to act
directly and effectively without having to apply the time-consuming
and ultimately inadequate precautions against emergency events.
[0040] The presented figures illustrate an implementation example

invention will be more clearly understood from the following

[0050] The invention is described below with the assistance of one
non limited example and with reference to attached drawings.
[0051] The protection school board of the present invention is of
rectangular cross section and has the configuration of a
rectangular parallelepiped room so that it can stand and be
extended horizontally easily and quickly in the floor of each
classroom. It can be manufactured in different dimensions (length,
width and height). Indicatively, it can be manufactured in
dimensions (L.times.W.times.H)=3.0.times.1.5.times.2.0 meters so
that the capacity could reach 9.0 cubic meters in order to
accommodate twenty-twenty five people.
[0052] As shown in FIG. 1, the protection school board of the
present invention comprises two main equal vertical surfaces
forming the frame construction, i.e. a main mobile outer frame of
rectangular cross section (1), which constitutes the front surface
of the room, with shape colored of dye blackboard (2), and a main
fixed frame of rectangular cross section (6), which is the rear
surface of the room, mounted on the wall of the classroom. The
frame consists of fixed and mobile parts, which are interconnected
via the suspension, operation and safety mechanisms and devices.
Both fixed and mobile parts may be composed of more than one
element from different material. The opposing parallel vertical
surfaces have the same dimensions and are composed of a high
hardness steel metal layer (12) which on its inner surface has a
special compact layer of insulating elastomer material (13) in
order to prevent heat transfer and maintain stable temperature
values.
[0053] The main fixed frame of rectangular cross section (6) that
constitutes the rear surface of the room is mounted to the wall of
the classroom. It is possible the main fixed frame of rectangular
cross section (6) to be placed inside the wall of the room for
space saving and optimal aesthetic result. As shown in FIG. 2 and
FIG. 7, along its inner surface (25), at a suitable height, at
least two screw shaft linear drive mechanisms (7) are supported by
bearings. The linear drive systems commonly use worm screws to
convert rotary motion to linear. The most common way of converting
rotary motion to linear is the screw drive mechanism for load
transfer along its length. The screw shaft thread is a trapezoid,
while on the contact position of each drive screw shaft, there are
at least two special nuts (8) having the same thread, but internal.
The thread of each drive screw shaft (7), from the beginning to the
middle of its length is clockwise (32) and then becomes left-hand
(33) making special nuts (8) to perform reverse movement between
them. Articulated joints (9) are adapted to the specific nuts (8)
in order to take place the necessary connections. Also in a
suitable point on the frame is mounted and the hybrid propulsion
motor (10) of the drive screw shafts (7) and the bottles of
compressed oxygen (11) of the electro-pneumatic operation
system.
[0054] The main mobile outer frame of rectangular cross section (1)
constitutes the front surface of the room and bears shape colored
of dye blackboard (2) in order to fulfill its primary scope within
the classroom. As shown in FIGS. 1 and 4, in its lower horizontal
surface, special drive bearings (3) are adapted so as to facilitate
movement during the folding of the school board, while it bears and
a protective thermoplastic elastomer bar (4) to prevent accidents
during the stay of students. Optionally, it bears along the
horizontal side, a film light-emitting diodes (5) for signaling of
protection school board at the start of its folding.
[0055] As shown in FIG. 3, the two equally sized folding
rectangular surfaces (15) which constitute the side surfaces of the
room are connected from their one vertical side (26) respectively
with the inner of two vertical sides of the main mobile outer frame
of rectangular cross section (1). The connection is made through a
device with pierced flat parts (27) in order to allow free turning
motion along the vertical axis. The two equally sized rectangular
folding surfaces (15) are also composed, as shown in the detail of
FIG. 1, of a high hardness steel metal layer (12) which on its
inner surface has a special compact layer of insulating elastomer
material (13).
[0056] As shown in FIGS. 2 and 5, the two equally sized folding
rectangular surfaces (15) which constitute the side surfaces of the
room, are connected on their other vertical side (28) respectively
with the inner of the two vertical sides of the main fixed frame of
rectangular cross section (6) via articulated joints (9) which are
adapted to special nuts (8) of the screw shaft linear drive
mechanisms (7). The movement of the special nuts (8), as shown in
the detail of FIG. 2, achieve the folding of the rectangular
surfaces (15) by 90.degree. degrees to the vertical axis and the
parallel movement of the main mobile outer frame of rectangular
cross section (1) forwardly through the drive bearings (3),
resulting to the creation of a parallelepiped room with absolute
contact of the vertical tangent surfaces, whose edges (24) are
coated with a polymer sealant material.
[0057] As shown in FIGS. 4 and 5, in the outer surface of the
equally sized folding rectangular surfaces (15) which constitute
the side surfaces of the room, an entry/exit door (19) is adapted
in order to take place the quick and easy transfer of persons. The
door (19) bears a special opening/closing strap (20).
[0058] FIGS. 5 and 8 illustrate the internal upper horizontal
surfaces (29) of the folding rectangular surfaces (15) which
constitute the side surfaces of the room, which are connected
respectively, through device with pierced flat parts (27), to the
two equally sized folding rectangular surfaces (16) which
constitute the upper surface of the room, to allow the rotation
movement along the horizontal axis. As shown in FIGS. 5, 6 and 8,
the movement takes place via at least two hydraulic compensator
cylinders (30) which are adapted at suitable points on the tangent
surfaces. On inner surfaces of the two equally sized folding
rectangular surfaces (16), kits with oxygen masks (18) are
suspended, as shown in FIG. 7, in case of chemicals substances
presence. Also, as shown in FIG. 6, safety lights (17) with power
batteries are installed, for the existence of continuous light and
continuous supply in case of power failure.
[0059] The two equally sized rectangular folding surfaces (16), as
shown in the detail of FIG. 1, are also composed of a high hardness
steel metal layer (12) which on its inner surface has a special
compact layer of insulating elastomer material (13). Also, as shown
in FIG. 6, their edges (24) are coated with polymeric sealant
material and are reinforced with metal plates (14) and also that
appropriate safety bolts (31) have been placed for enhancing their
resistance.
[0060] The protection school board when is not used, due to its
property to be folded easily and quickly, is firmly mounted
(non-extended form) on the wall of the classroom, with the shape
colored of dye blackboard (2) in order to fulfill its main scope,
as shown in FIG. 9.
[0061] The process of folding and horizontally extending of the
school board to a rectangular room of parallelepiped shape, starts
by pushing the start/stop button of the external unit (21) (FIG. 9)
for setting in operation the hybrid propulsion motor (10) which is
connected with the drive screw shafts (7). Alternatively the
protection school board is equipped with backup power supply system
and pneumatic operation system, in case of interruption of supply.
In case of power supply failure of the above mentioned systems,
there is installed a manual operation mechanism with a pressure
lever (22).
[0062] By pressing the external unit with the pushbutton start/stop
(21) at the same time starts the automated sound information system
with alarm notification and the recorded instructions, and also the
signaling of the school board with the film light-emitting diodes
(5).
[0063] Afterwards, takes place the folding of the surfaces in order
to form the room. The executed movements are the following: [0064]
As shown in FIG. 10, while the drive screw shafts (7) rotate, the
special nuts (8) executing reverse movement between them, achieve
the folding of the rectangular surfaces (15) which form the side
surfaces of the room by 90.degree. degrees to the vertical axis as
well as the parallel forward movement of main mobile outer frame of
rectangular cross section (1), through drive bearings (3),
resulting in the formation of a parallelepiped room without roof,
with absolute contact of vertically tangent surfaces. [0065] Then,
as illustrated in FIG. 11 when folding of the rectangular surfaces
(15) which constitute the side surfaces of the room is completed,
at least two hydraulic compensator cylinders (30) are automatically
actuated resulting in the full extension of the folding rectangular
surfaces (16) by turning 90.degree. degrees to the horizontal axis.
[0066] Result of the above mentioned movement, as shown in FIG. 12,
is the creation of the rectangular cross section room,
parallelepiped shaped, with one single surface that constitutes the
roof. [0067] Since the protection school board is fully folded with
minimum speed time, students and staff enter through the
door/s/entry/exit (19), securing the safety bolts (31) (FIG. 13).
Alongside safety lights are activated, and oxygen masks (18) are
available in case of emergency. [0068] When the danger is passed,
evacuation process takes place and through the reverse operation,
takes place its shrinking to a typical school board.
[0069] The student's protection school board from emergencies,
apart from being placed in places that host children such as
schools, language schools, etc., can also be used in all areas
where there is human activity, such as convention centers, shopping
centers, hospitals, sports centers, hotels, tourist and
archaeological sites etc.
