Description

Title: Shielding screen with inflatable edge body

BACKGROUND OF THE INVENTION The present invention relates to a shielding screen for placement in a three-dimensional room, to shield a first compartment of the three-dimensional room with respect to a second compartment of the three-dimensional room. The invention further relates to a shielding screen system and a method for shielding a first compartment of a three-dimensional room with respect to a second compartment of said three-dimensional room.

Such screens are e.g. used in cars to shield a driver from passengers and/or to shield the front seats from the back seats. There are generally two types of such shields: permanent ones and temporary ones.

Permanent shielding screens can e.g. be found in various taxis around the world. For example the city of New York in the United States of America requires taxis to have a permanent and impact-proof screen to protect the taxi driver from aggressive passengers. Similar screens can e.g. be found in cabs in London, the United Kingdom. Permanent shielding screens are typically rigid, require a long installation time, and are expensive.

Temporary shielding screens in taxis may e.g. be used in times of an epidemic or pandemic to protect the taxi driver from any viruses with which passengers are infected and, vice versa, to protect passengers from any viruses with which the taxi driver is infected. Temporary shielding screens may be removed when the epidemic or pandemic is over. Temporary shielding screens may e.g. further be used during the flu season in a like manner. Temporary shielding screens must comply with all kinds of regulations to guarantee the safety of both the passengers and the taxi driver. They preferably do not contain any rigid parts. Preferably, they can be mounted inside the taxi without leaving a permanent trace.

At present, such a shielding screen for temporarily use is not available on the market. It is an object of the invention to provide such a shielding screen.

SUMMARY OF THE INVENTION Accordingly, a first aspect of the present invention relates to a shielding screen for placement in a three-dimensional room, to shield a first compartment of said three-dimensional room with respect to a second compartment of said three-dimensional room, the shielding screen comprising: - an inflatable edge body having an inflation opening configured to receive an inflation material therein to inflate the inflatable edge body; and - a film layer, connected to the inflatable edge body in a fluid-tight manner and spanning a shielding area defined by the inflatable edge body; wherein the inflatable edge body is configured to shape itself in accordance with a cross section of the three-dimensional room in an inflated state thereof, the inflatable edge body being configured to contact at least one partition and preferably at least three partitions of said cross section in its inflated state.

The shielding screen is designed to be placed in a three-dimensional room, to shield a first compartment of said three-dimensional room with respect to a second compartment of said three-dimensional room. Hence, the room comprises at least two compartments after the shielding screen is placed therein, the compartments being separated from each other by the shielding screen. However, as will be explained in the below, more shielding screens may be placed in the room to divide it in more than two compartments.

Within the context of the present document, the word “shield” means that a physical barrier is present between the two compartments in the room. It is however not required that it is impossible for e.g. objects, liquids or gas to be exchanged between the first compartment and the second compartment, or vice versa. In other words, the shielding screen is not necessarily configured to completely seal the first compartment with respect to the second compartment, although this may be possible in embodiments.

Within the context of the present document, the word “seal” means that a physical barrier is present between the two compartments in the room, the physical barrier substantially preventing all objects, all fluids, and all gasses to move from the one compartment to the other compartment. The intention however is not necessarily to provide a cleanroom, such as a medical cleanroom, so the sealing may be less than 100% effective compared to such a cleanroom. The shielding screen as presented herein comprises an inflatable edge body having an inflation opening configured to receive an inflation material therein to inflate the inflatable edge body. For example, the inflation material may be a fluid, i.e. a gas or a liquid. Preferably, if the inflation material is a fluid it is air. In another example, the inflation material may be a foam material. As the inflatable edge body may be inflated, it has a deflated state in which the inflatable edge body is substantially free of inflation material and may be compressed, as well as an inflated state, in which the inflatable edge body comprises the inflation material and is swollen.

As inflation opening e.g. a valve may be used when the inflation material is a fluid. The invention is not limited to the use of any particular kind of valve. Preferably the valve is easy to operate, cheap, and has a limited number of protruding, hard components. The valve may include an overpressure vent.

The shielding screen as presented herein further comprises a film layer. The film layer is connected to the inflatable edge body in a fluid-tight manner and spans a shielding area defined by the inflatable edge body. Preferably, the film layer is formed by a single or double sheet of a flexible and transparent plastic material, that physically closes an area bordered by the inflatable edge body. Many different alternatives are known to a person skilled in the art to connect a film layer to an inflatable edge body in a fluid-tight manner. Examples of such connections are gluing, heat shrinking, stitching, stapling and moulding. Many other connection types are however known; the invention is not limited to any particular kind of fluid-tight connection.

Preferably the film layer is flexible in the sense that its shape can be altered with a relatively low force, e.g. applied on it by inflating the inflatable edge body or by applying a force on it with fingers of a person. For example, the film layer may have a thickness of less than 5 mm, e.g. less than 2 mm, such as 0.5 mm or 0.2 mm.

Whereas the inflatable edge body may be substantially shapeless when it is in its deflated state, as it is inflated the inflatable edge body becomes more rigid and stiff while still being mouldable to some extent, e.g. depending on the state of inflation, the material of the body and the inflation material being used. The inflatable edge body is configured to shape itself in accordance with a cross section of the three- dimensional room in its inflated state. The cross section may e.g. be arranged in a lateral or longitudinal direction of the room. As known by one skilled in the art, a cross- section of a three-dimensional room will typically be a two-dimensional plane. That is, when the shielding screen is e.g. arranged in a lateral direction of a car, the inflatable edge body is configured to shape itself in accordance with the shape of the ceiling and/or walls and/or floor of the car at the location where the shielding screen is positioned and along the entire circumference of the inflatable edge body.

The inflatable edge body is furthermore configured to contact at least one partition, i.e. floor, wall, ceiling, etc., and preferably at least three, partitions of said cross section in its inflated state. By contacting the at least one partition of the room, the inflatable edge body prevents an easy flow of air along said partition and shields the two compartments of the room from each other.

Advantages of the shielding screen as presented include, but are not limited, to the following.

By using an inflatable edge body, there is some freedom in the precise shape that is obtained when inflating the screen. This allows a single screen of certain dimensions to be used in several different rooms, provided the rooms are somewhat similar in shape / size. More in particular, when the room is e.g. a car, several types of cars can benefit from one shielding screen having the same dimensions. As a result thereof, a relatively small number of screen designs and sizes can suffice to serve the majority of the market, without the need to design a new and unique screen for each and every type of car. While there is some freedom in the shape of the screen that is obtained when inflating it, the inflatable edge body simultaneously allows for a relatively stiff screen when it is inflated, resulting in a screen that remains in place.

By using an inflatable edge body, a self-clamping screen may be obtained. By inflating the edge body until it contacts at least one partition of the room, a pushing force may be exerted on said partitions, to clamp the screen in the room without using any external aids. Also, the clamping force may be spread over a large area, leading to a secure placement of the shielding screen.

Owing to this self-clamping effect, and compared to a screen without an inflatable edge body, e.g. consisting solely of a film layer, an advantage of the present screen is that it may be attached to the room without leaving a mark on the partitions of the wall. Still, the shielding screen may in embodiments comprise one or more connectors for attaching the shielding screen to its surroundings.

A further advantage is that the inflatable edge body allows for a relatively air-tight attachment, as the flexibility of the edge body allows it to mould itself to the shape of the room it is placed in, to close any holes between a partition of the room and the shielding screen. In that respect, it is particularly advantageous when 5 the inflatable edge body is made of a rubbery / stretchable material.

By using an inflatable edge body, preferably in combination with a flexible film layer, an impact between the screen and a person is usually not severe, not resulting in injuries to the person. This is e.g. advantageous when the screen is used in a car and the car is involved in an accident.

In an embodiment of the present invention, the inflatable edge body is configured to contact all partitions of said cross section in its inflated state, to seal said first compartment of the three-dimensional room from said second compartment of the three-dimensional room. This substantially prevents any exchange of gas, liquids, and objects between the first compartment and the second compartment, and optimally prevents the exchange of viruses, bacteria, etc. from a person in the first compartment to a person in the second compartment, or vice versa.

In an embodiment of the invention, the three-dimensional room is a transport vehicle, such as a car, e.g. a taxi, a van, a bus, a subway, an aircraft or an elevator. However, also other rooms such as emergency tents and other tents or temporary buildings may benefit from the use of a shielding screen as presented herein.

In an embodiment of the invention, the cross section is arranged in a lateral direction of the transport vehicle. Preferably, when the transport vehicle is a car, the shielding screen is placed directly behind and against the backside of the front seat(s) of the car, as this location provides the most comfort to both driver and passengers seated on the back seat. On the one hand, the driver will barely notice the physical presence of the shielding screen, while the available leg space for passengers on the back seat is least impacted by this specific arrangement.

In an embodiment of the invention, the shielding screen further comprises a head rest pin connector attached to the film layer, the connector being configured to connect the shielding screen to a head rest pin of the transport vehicle. This allows to additionally secure the shielding screen with respect to the room it is placed in. Advantageously, when the shielding screen is connected to a head rest pin,

this allows to secure the shielding screen in place without damaging the upholstery of the transport vehicle. In an embodiment of the invention, the cross section is arranged in a longitudinal direction of the transport vehicle. For example, when the transport vehicle is a car, the shielding screen may be placed between the left front seat and the right front seat, and/or between the left back seat and the right back seat of the car, in a longitudinal direction of the car. In an embodiment of the invention, the shielding screen further comprises a partition connector attached to the inflatable edge body, the connector being configured to connect the shielding screen to a partition of the three-dimensional room, directly or indirectly. A partition connector may have one or multiple functions. For example, when the cross section of the room, at the location where the shielding screen is to be placed, has a relatively sharp corner, the inflatable edge body may not be able to shape itself completely in the shape of the partition by itself. The two compartments are then not optimally shielded from each other, and a gap remains between the shielding screen and the partition of the room. By providing the edge body with a connector at such locations, and connecting said connector to a corresponding connector mounted on a partition of the room, an external force may be applied on the inflatable edge body to shape it in the desired shape, close the gap and improve the shielding of the shielding screen. Besides this, a connector may help to more firmly and securely mount the shielding screen in the room. The connector may e.g. be attached directly to the partition itself, or e.g. mounted to a seat of a car, which seat is firmly and rigidly mounted on a chassis of the car. In the latter case, the connector is mounted indirectly to the partition of the room.

In an embodiment of the invention, the inflatable edge body completely surrounds the film layer. In such embodiments, the inflatable edge body may e.g. be formed as a single tube, that may be endless.

In alternative embodiments however, the inflatable edge body may e.g. be U-shaped or inversely U-shaped.

In an embodiment of the invention, the film layer and/or the inflatable edge body are made from a flexible material, preferably a flexible plastic material. A plastic material has e.g. the advantage that it may be cleaned easily. When the film layer and/or the inflatable edge body are made of a flexible material, that preferably has some resilience / stretching properties, this allows a great freedom to shape the shielding screen as the edge body is inflated. This e.g. allows to seal both sharp and blunt corners in the plane of the cross-section as well as in the plane protruding with respect to the cross-section, as the inflatable edge body can easily form itself around or into any such corners.

More specifically, the inflatable edge body may e.g. be made from a polyurethane, ethyl tetra fluor ethylene (ETFE) or butyl material, e.g. having a thickness of at least 50 um up to about 5000 um, e.g. about 100 ym or about 200 um or about 500 um. An advantage of such materials is that the diameter thereof increases when an internal pressure is applied thereon. This helps in moulding the inflatable edge body around any corners in the cross section of the room and in closing any gaps to better seal and/or shield the two compartments from each other.

More specifically, the film layer may e.g. be made from polyurethane or ethyl tetra fluor ethylene (ETFE) foil material. These are examples of lightweight and transparent materials that is easily formed in another shape when a small force is applied to it, e.g. by the inflatable edge body. Additionally, when using ETFE as film layer in a taxi, it is possible for a passenger located in the second compartment of the taxi to pay a taxi driver located in the first compartment of the taxi by contactless money transfer using a debit or credit card by the passenger and a pin terminal by the taxi driver. This is an advantage compared to e.g. using Plexiglas, through which such contactless money transfer is not possible. However the film layer may also be made of a rigid material, such as Plexiglas, without departing from the invention.

In an embodiment of the invention, the film layer and the inflatable edge body are made from a transparent material. This allows to see through the shielding screen, which is particularly advantageous when the shielding screen is used in a transport vehicle as this minimizes the visual obstruction for the driver of the vehicle.

In an embodiment of the invention, the film layer comprises an opening and the shielding screen further comprises a patch member for releasably covering said opening. This allows contact between a person in the first compartment of the room and a person in the second compartment of the room. When the shielding screen is arranged in a taxi, this e.g. allows a passenger in the second compartment to pay the driver in the first compartment.

In another embodiment of the invention, the film layer comprises an opening to allow air from the first compartment to be introduced in the second compartment, or to allow air from the second compartment to be introduced in the first compartment. Preferably, such flow of air is one-directional, i.e. from one compartment to the other but not back. For example, this allows to cool the second compartment with an air-conditioning unit arranged in the first compartment. A seal may e.g. be provided over the opening in the film layer which allows air to flow in one direction only. In an embodiment of the invention, the shielding screen comprises a coupler for coupling the shielding screen to a further shielding screen. In this way, a shielding screen system may be obtained. For example, the shielding screen may comprise a fist shielding screen configured to be arranged in a lateral direction of the room and a second shielding screen configured to be arranged in the longitudinal direction of the room. This allows to divide the room in three compartments, or even more. In the example of a car, a first shielding screen may be arranged between the row of front seats and the row of back seats, while a second shielding screen may be arranged between the left front seat and the right front seat, the first and second shielding screen being coupled to each other. Alternatively and/or simultaneously, the shielding screen arranged in the longitudinal direction of the car may be arranged between the left rear seat and the right rear seat.

A second aspect of the invention relates to a shielding screen for placement in a three-dimensional room, to shield a first compartment of said three- dimensional room with respect to a second compartment of said three-dimensional room, the shielding screen comprising: - an edge body made of a foam material; and - a film layer, connected to the edge body in a fluid-tight manner and spanning a shielding area defined by the edge body; wherein the inflatable edge body is configured to shape itself in accordance with a cross section of the three-dimensional room when mounted therein, the edge body being configured to contact at least one and preferably at least three partitions of said cross section in its mounted state.

Compared to the first aspect of the invention, an edge body made of a foam material is able to achieve the same or like benefits. Like an inflatable edge body, an edge body of foam is able to adapt its shape to close and seal a partition it is placed against. Preferably the foam has a closed cell structure, so that it additionally prevents air, fluids and objects to be exchanged between the first and the second compartment of the room. Preferably the foam has an internal reinforcement element such as a copper or iron wire to provide the edge body with more rigidity and stiffness.

The shielding screen according to the second aspect of the invention may benefit from embodiments described in relation to the first aspect only.

A third aspect of the invention relates to a method for shielding a first compartment of a three-dimensional room with respect to a second compartment of said three-dimensional room, wherein use is made of a shielding screen as described in the above, or a shielding screen system as described in the above, the method comprising the steps of: - arranging the shielding screen or the shielding screen system inside the three-dimensional room; - inflating the inflatable edge body until said inflatable edge body contacts at least one partition of said three-dimensional room.

Of course, the steps are not necessarily carried out in the same order as described in the above. It is also possible to first inflate the inflatable edge body and only then arrange the shielding screen in the room.

In an embodiment of this method, the shielding screen or one shielding screens of the shielding screen system is placed behind front seats of a car, in a lateral direction of the car.

A fourth aspect of the present invention relates to the use of a shielding screen as described in the above or a shielding screen system as described in the above to divide a room in at least a first compartment and a second compartment.

A fifth aspect of the present invention relates to a transport vehicle comprising a shielding screen as described in the above or a shielding screen system as described in the above.

These and other aspects of the invention will now be elucidated further with reference to the attached figures.

BRIEF DESCRIPTION OF THE FIGURES Figure 1 schematically illustrates in isometric view a first embodiment of the shielding screen according to the present invention; Figure 2 schematically illustrates in isometric view a second embodiment of the shielding screen according to the present invention; Figure 3 schematically illustrates in an isometric view a third embodiment of the shielding screen according to the present invention Figures 4A — 4C schematically illustrate in cross-sectional view different embodiments of an edge body in accordance with the present invention.

DETAILED DESCRIPTION OF THE FIGURES With reference to Figure 1, a part of the interior of a car 200 is shown. The view in Figure 1 is approximately taken from the back seats of the car 200, wherein the back of front seats 202 are visible. The interior of the car 200 defines a room 100. The room 100 is defined by a ceiling 103, a left wall 104, a right wall 105 and a floor 106. The different partitions 103, 104, 105, 106 may be seamlessly integrated by upholstery of the room 100. Arranged inside the room 100 is a shielding screen 1. The shielding screen 1 divides the room 100 in two compartments 101, 102, one compartment 101 housing the front seats 202 and the other compartment 102 housing the back seats and shields the two compartments 101, 102 with respect to each other. Although the screen 1 contact all partitions 103, 104, 105, 105 of the room 100 to completely seal the two compartments 101, 102 from each other, this is not required. As shown in Figure 1, the bottom of the shielding screen 1 is free of the floor 106 of the room 100.

In the below, the edge body will be referred to as inflatable edge body 11. One skilled in the art will however understand that instead of an inflatable edge body 11, alternatively an edge body of foam material with a closed cell structure may be used. Such an edge body of foam material has the same properties as an inflatable edge body 11 in the sense that it can also change it shape depending on the shape of the room at the cross-section where it is placed.

The screen 1 is here shown while it is installed in the room 100 and while it is in its inflated state. The inflatable edge body 11 is inflated by blowing air through the inflation opening 111. The film layer 12, which is connected to the inflatable edge body 11 at the inner side thereof, forms a shielding area between the front seats 202 and the back seats. The film layer 12 is connected to the inflatable edge body 11 in a fluid-tight manner, as will be explained in some more detail in the below, with reference to Figure 4A.

As can be seen in Figure 1 the shielding screen 1, which is relatively form-free, has shaped itself in accordance with a cross-section of the room 100. Upon inflating the inflatable edge body 11, the screen 1 assumes the shape of the car interior, and contacts the ceiling 103, the left wall 104 and the right wall 105.

Owing to this freedom to shape itself in accordance with the two-dimensional shape of the room in which the screen 1 is placed, the screen 1, being of a universal shape, divides the room 100 in two compartments 101, 102 and shields the two compartments 101, 102 with respect to each other. It is explicitly noted that, if the same screen 1 would have been placed in a room of a different shape, the shape of the screen obtained when inflating it and upon contacting the partitions of the differently-shaped room, would also be different. However, also in this differently- shaped room the screen would likewise be successful in shielding a first compartment from a second compartment. Of course, this only works to a certain extent. If the dimensions and shapes vary too much, a different screen should be used. However there is a significant amount of flexibility in the shape the screen can assume, allowing the same screen to be used in a multitude of car types.

As shown here, the screen 1 is arranged in the lateral direction of the car 200, directly behind the front seats 202. Although the shielding screen 1 is self-clamping as it contacts three partitions 103, 104, 105 of the car interior, further connectors 14, 15 are here used to more rigidly fixate the position of the shielding screen 1. It is noted that such further connectors 14, 15 are optional.

A first pair of connectors 14, e.g. of the Velcro type, is attached to the film layer 12. For example, the connector 14 may be glued to the film layer 12, but many alternative ways to attach a connector to a film layer 12 are known to one skilled in the art. The connector 14 here connects the shielding screen 1 to head rest pins 201. Advantageously, this allows the shielding screen 1 to be attached to a structure rigidly mounted in the room 100 without leaving a permanent mark.

A second pair of connectors 15A is used to attach the shielding screen 1 to the upholstery 104, 105 of the car 200, and hence directly to the partitions of the room.

A third pair of connectors 15B is used to attach the shielding screen 1 to the front seats 202 of the car 200 and hence indirectly to the partitions of the room.

In the embodiment of Figure 1, the inflatable edge body 1 circumscribes the film layer 12 and is shaped as an endless tube.

As follows from Figure 1, and as preferred, both the inflatable edge body 11 and the film layer 12 are made of a transparent material, to least obstruct the view of the driver. To increase the self-shaping properties of the shielding screen, i.e. the property that the screen shapes itself in accordance with the cross section of the room in which it is placed, preferably both the film layer 12 and the inflatable edge body 11 are made of a flexible material that can easily be deformed.

Turning to Figure 2, the shielding screen 1 shown here is placed in the same position in a car 200 as in Figure 1, to divide the interior 100 of the car 200 in a first compartment 101 and a second compartment 102. Compared to the embodiment shown in Figure 1, no additional connectors are here needed to secure the shielding screen 1 in place. Further in contrast with the embodiment shown in Figure 1, the inflatable edge body 11 shown in Figure 2 does not fully circumscribe the film layer 12 but is rather U-shaped. As shown, and following the same principles as described in relation to Figure 1, as the inflatable edge body 11 is inflated it forms itself in the shape of the cross-section of the room at the position where it is placed. By inflating the edge body 11, the edge body 11 contacts and pushes against the partitions 103, 104, 105 of the room 100, and shields the first compartment 101 with respect to the second compartment 102.

Turning to Figure 3, a shielding screen 1 is shown here that is placed in the longitudinal direct of the car 200. Whereas the screens shown in Figures 1 and 2 divides the car interior 100 in “front” and “rear” compartments 101, 102, the screen 1 of Figure 3 divides the car interior 100 in “left” and “right” compartments 101, 102. The shielding screen 1 may extend from the back seat to the window of the car 200, or may e.g. be coupled with a screen as shown in Figures 1 and 2.

Turning to Figures 4A — 4C, several embodiments of a double- walled edge body 11, 21 are shown. Shown in each of the figures 4A — 4C is the film layer 12, attached to first edge body 11. The first edge body 11 may e.g. be an inflatable edge body 11 as described in the above, the first edge body 11 here being in the inflated state. Alternatively the first edge body 11 may be an edge body made of a foam material with a closed cell structure. Attached to the first edge body 11 at welding points 22 is a second edge body 21, the second edge body 21 being an inflatable edge body 21. As shown in figures 4A — 4C, there are several configurations in which a double-walled edge body 11, 21 can be made. Three different configurations are here shown, but of course many more can be thought of.

The inflatable edge body 21 is shown in both its semi-inflated state 21A and its inflated state 21B. Compared to a single edge body, a double-walled edge body has even more freedom in the shape it can assume when inflated, even further improving the shielding and sealing properties of the shielding screen.

To make optimal use of the double-walled edge body 11, 21, preferably the edge body 11 is inflated in use to provide the shielding screen with rigidity and stiffness. The edge body 21 is simultaneously semi-inflated to optimally fill any gaps between a partition and the shielding screen. In other words, when installed in a room the inner edge body 11 of the double-walled edge body has a higher internal pressure than the outer edge body 21 of the double-walled edge body.
