Description

DEFORMABLE PROTECTIVE SUPPORT

The present invention relates to a deformable protective support or wrapper of the type pointed out in the preamble of the first claim.

In particular, the invention concerns a protective support or wrapper adaptable to the outer profile of at least part of an object so as to surround it and protect it against impacts, shocks and/or external agents such as sudden changes of temperature and moisture, for example.

It is known that the protective supports presently used can be substantially divided into two classes, the stiff ones and the deformable ones.

The stiff supports vary based on the use they are conceived for, and therefore they differ from each other as to the materials used and the shape, which elements change depending on the object to be protected. These supports are greatly linked to the object they have to protect and therefore they are hardly adaptable to objects of different conformation.

The second supports, i.e. the deformable ones, do not have a stiff structure thus being easily adaptable to objects having shapes and sizes different from each other.

These deformable supports are usually made up of an outer wrapper, generally of polymeric material, adapted to enable the product to be protected against external agents, and of an inner structure adapted to absorb stresses resulting from an impact.

Therefore, the most important part appears to be the inner structure that, depending on the expected impacts, is usually made of an elastomeric material or solid foams. In detail, these solid foams can be of the open-cell type, if a high deformability is required, or of the closed-cell type if, on the contrary, more ability to resist the impacts is necessary.

The above mentioned known art has some important drawbacks.

A first problem consists in that these solutions never constitute the optimal choice but merely represent a compromise between the requirement of adapting themselves to the outer profile of the object to be covered and that of bearing high stresses.

Another problem is represented by the degree of deformability of the currently made supports that is not very high, so that they have a poor adaptability to the profile of the object to be protected. In particular, while use of inner structures made of open-cell foams offers an improved adaptability of the support as compared with those made of other materials, however it does not ensure an appropriate deformation and therefore a sufficient adaptability of the support to the object's profile.

In detail, this imperfect and imprecise coupling between support and object may give rise, in case of an impact, to creation of too strong stresses in the contact region between support and object that can lead to breaking of the object.

In conclusion, these protective supports are almost useless for storage of brittle products such as bottles.

Under this situation, the technical task underlying the present invention is to conceive a deformable protective support capable of substantially obviating the mentioned drawbacks.

Within the scope of this technical task it is an important aim of the invention to create a protective support characterised both by high deformability and great ability to absorb impacts.

Another important aim of the invention is to obtain a support of a particularly simple use and reduced cost.

The technical task mentioned and the aims specified are achieved by a deformable protective support as claimed in the appended Claim 1.

Preferred embodiments are highlighted in the sub-claims.

The features and advantages of the invention are hereinafter clarified by the detailed description of a preferred embodiment of the invention, with reference to the accompanying drawings, in which:

Fig. 1 is a view of the deformable protective support according to the invention;

Fig. 2a shows a section of the support in a first configuration; and

Fig. 2b shows a second position of the deformable protective support in a second configuration;

Fig. 3a is a section of a further deformable protective support or wrapper; and

Fig. 3b is a section of the support or wrapper shown in Fig. 3a in a different stage of use.

With reference to the drawings, the deformable protective support or wrapper according to the invention is generally identified by the reference numeral 1.

This deformable support is suitable to internally house at least one portion of an object 10 and protect it both from impacts and from possible external agents, such as moisture and sudden temperature changes that can damage the object itself. This object 10 can therefore consist both of an element of small sizes, such as a bottle or a camera, and of elements of big sizes, a screen for example.

The deformable protective support 1 comprises an outer wrapper 2 defining a housing volume 2a adapted to hold at least part of the object 10. Inserted in the housing volume 2a is at least one inner wrapper 3 adapted to be disposed in contact with at least the aforesaid part of object 10 and confining at least one operating chamber 3a internal to the housing volume 2a. Provided in the operating chamber 3a is a plurality of distinct particles 4.

In detail, the outer wrapper 2 is adapted to define a hermetic housing volume 2a when the support 1 tightly surrounds the object 10, as hereinafter described. It is therefore made of a material impervious to passage of air (airtight material) and preferably of a polymeric and flexible material.

For instance, the outer wrapper 2 is made of Neoprene®, polyvinylchloride or still other materials.

The outer wrapper 2 has a profile adapted to define a housing volume 2a capable of holding the whole portion of the object 10 to be protected. Preferably, object 10 is a brittle object, such as an electronic device, a glass element or others, but said object 10 may even be a portion or a human body or others.

In order to enable introduction of the object into such a cavity, one or more orifices 2b are provided as well as closing means 2c adapted to obtain a hermetically sealed closure of said orifices 2b, i.e. a closure adapted to prevent passage of air therethrough.

In detail, if the object 10 is only partly housed in the deformable support 1 , the outer wrapper 2 abuts against the object 10 at least at one of the orifices 2b and therefore the closing means 2c comprises elastic strips, Velcro or other similar means adapted to shut and fasten the orifice 2b to the object 10 so as to obtain said hermetic closure. Alternatively, if the object 10 is fully stored in the housing volume 2a, the closing means 2c is adapted to sealingly close the orifice 2b and therefore comprises an impermeable zip (Fig. 1), Velcro or other similar element adapted to perform the aforesaid function.

Inside the housing volume 2a, the deformable support 1 has the inner wrapper 3 which is possibly partly secured to the outer wrapper 2 by means of glues, seams, Velcro or other similar solutions.

The outer wrapper 2 delimits an operating chamber 3a disposed between the two mutually secured wrappers 2 and 3 and constituting a single vessel for the distinct particles 4.

In particular, the operating chamber 3a is preferably obtained by the inner wrapper 3 alone. Specifically, in the example shown in Figs. 2a and 2b, the inner wrapper 3 consists of a single membrane or bladder closed upon itself to define an operating chamber. Closure is obtained through seams, glues or others for example, in such a manner as to prevent the distinct particles 4 housed in the inner wrapper 3, from coming out of the operating chamber 3a. The inner wrapper 3 is adapted to bring the operating chamber 3a into connection for gas passage with the housing volume 2a, so that the operating chamber 3a has the same pressure as the housing volume 2a. In particular, this connection for gas passage is obtained through a wrapper adapted to be passed through by air or another gas and having perforations for example, or preferably made of a gas-permeable material.

In addition, it is made of an elastically deformable material so as to vary its length in response to an outer load. Preferably, it is made of an elastic material characterised by a low modulus of elasticity, preferably of elastane, i.e. a synthetic polyurethane fibre known on the market as Lycra®.

As an alternative to chamber 3a defining a single vessel for the distinct particles 4, support 1 has separation means 6 adapted to divide the operating chamber 3a into a plurality of sub-chambers 6a and, in particular into a plurality of consecutive sub-chambers 6a each of which is adapted to contain the distinct particles 4.

This means 6 therefore creates sub-volumes 5a substantially characterised by the same elasticity and deformability as the operating chamber 3a and connected for gas passage both mutually and with the housing volume 2a. For maintaining the elasticity and deformability features and said connection for gas passage, the separation means 6 consists of seams, partitions or other similar means made of the same material as that of the inner wrapper 3, and therefore of elastane, i.e. Lycra^®.

The support 1 has at least connecting means 5 such as a valve or other similar device, adapted to define an opening capable of bringing the housing volume 2a and the outer environment into mutual connection for gas passage, usually air passage. In addition, the connection obtained by the connecting means 5 is of the type taking place upon command and therefore opening and closure of such a connection for gas passage exclusively occurs based on a command given by the user, as utilised in inflatable mattresses or in life buoys or belts. Preferably, the connecting means 5 comprises a nonreturn valve, i.e. a valve adapted to prevent spontaneous admission of air into the support 1 , by maintaining the housing volume 2a hermetically sealed. More specifically, it is adapted to enable entry of gas into the housing volume 2a exclusively in response to a given command or action carried out by the user. Alternatively, the connecting means 5 may comprise an opening adapted to be connected to a known vacuum machine that first enables air to be extracted from volume 2a and then allows sealing of the opening to be carried out, thus preventing air passage. In this case the connecting means could be coincident with orifice 2b.

In detail, the connecting means 5, upon command of the operating chamber 3a, enables the housing volume 2a and consequently the volume of the operating chamber 3a to be varied, thus defining an expanded configuration and a compressed configuration of support 1 .

In the expanded configuration shown in Fig. 2a, the housing volume 2a substantially has the same pressure as that of the external environment and therefore the deformable support 1 has maximum extension.

On the contrary, in the compressed configuration shown in Fig. 2b, the housing volume 2a, due to suction of air through the connecting means 5 and inner volume 3, is under vacuum so as to tighten the support 1 on the object 10, as hereinafter described.

In the compressed configuration, since the operating chamber 3a is in connection for gas passage with volume 2a, due to the particular material the inner volume 3 is made of, said chamber tends to become compressed on the object 10 pressing the distinct particles 4 against each other thus preventing them from carrying out a mutual motion. In particular, in this configuration the distinct particles 4 are mutually pressed between the inner volume 3 and the object 10 and therefore they become compacted defining at least one stout or resistant element 4a, i.e. a substantially stiff body adapted to protect the object 10. In detail, in the compressed configuration either a single resistant element 4a can be created, as shown in Figs. 2a and 2b or, alternatively, several resistant elements 4a (Figs. 3a and 3b) having sizes and shapes different from each other.

In addition, for the purpose of forming the resistant elements 4a, the material constituting the distinct particles 4 is a material adapted to enable the particles to adhere to each other when compressed. In detail, this material is preferably a polymer and, more specifically, a thermoplastic polymer.

The resistant elements 4a, obtained through compacting of the distinct particles 4, consist of a bladder of distinct particles 4 surrounding at least one portion of the object 10, so as to protect it. In particular, each resistant element is substantially less than 10 cm thick, preferably less than 5 cm, and more preferably less than 3 cm thick and its thickness can be different from one element 4a to another one 4a.

On the contrary, in the expanded configuration, the operating chamber 3a or the sub-chambers 6a have the same pressure as the external environment and therefore are unable to press the distinct particles 4 against each other so as to form the resistant element 4a.

In detail, in the expanded configuration, the distinct particles 4 are adapted to take up a volume substantially higher than 50% of the volume taken up by the operating chamber 3a or the sub-chambers 6a in the expanded configuration. Preferably, said volume of particles 4 is practically higher than 70% and, more preferably, substantially higher than 90% of the volume taken up by the operating chamber 3a or the sub-chambers 6a in the expanded configuration. In particular, the deformable protective support or wrapper 1 can contemplate the presence of different amounts of distinct particles 6 inside the sub- chambers 6a so as to obtain resistant elements 6a having different thickness and therefore different ability to resist impacts or other similar concentrated forces.

In addition, in order to ensure an appropriate covering of object 10, the distinct particles 4 disposed in an operating chamber 3a or a sub-chamber 6a are of such a number that they define a resistant element 4a covering at least 50% of the inner surface of the outer wrapper, i.e. the surface of the outer wrapper 2 facing the object 10 when the deformable support 1 is in the compressed configuration.

Said portion of inner surface covered with the resistant element 4a (Fig. 2b) or resistant elements 4a (Fig. 3b) is preferably almost at least 75% and more preferably almost the whole of said inner surface so as to protect the whole portion of object 10 that is housed within the deformable support 1.

Operation of the deformable protective support or wrapper described above mainly as regards structure, is the following.

Initially the deformable protective support 1 appears in the expanded configuration (Figs. 2a and 3a), i.e. the outer volume 2 defines the maximum receiving volume 2a.

At the moment of use, the user introduces the object 10 into the support 1 through the orifice 2b. In detail, the object 10 during introduction is pressed against the inner wrapper 3 that, due to its ability to be elastically deformed, becomes expanded and wraps the object 10.

In particular, the inner wrapper 3, due to the advantageous difference in volume between the volume defined by the wrapper itself and that taken up by the distinct particles 4, is submitted to extension at the moment the object 10 is introduced. This extension causes arising of return stresses acting on the inner wrapper 3, i.e. forces tending to bring the wrapper 3 back to the expanded configuration.

Once the object 10 has been placed inside the deformable support 1 , the user hermetically closes the orifice 2a through the closing means 2c and, if necessary, distributes the distinct particles 4 in a uniform manner around the object 10 through manual pressure exerted on the outer wrapper 2.

When redistribution has been completed, the user through the connecting means 5 (a valve to which a pump is connected, for example) draws air from the inside of the deformable support 1 bringing volume 2a and therefore the operating chamber 3a to vacuum pressure, i.e. to a pressure lower than the ambient pressure.

This action, due to connection for gas passage between the housing volume 2a and sub-volumes 5a, puts the housing volume 2a and sub-volumes 5a under vacuum so that they become elastically compressed adhering almost perfectly against the portion of object 10 to be supported.

In detail, due to the vacuum, and as a result of this operation, wrappers 2 and

3 are clenched against the object 10 thereby tending to compress the distinct particles 4 against each other thus giving rise to formation of at least one resistant element 4a (Fig. 2b) or, alternatively, several resistant elements 4a

(Fig. 3b).

When it is wished to extract object 10 from support 1 , the user brings the support 1 back to the expanded configuration. The user, through opening of the connecting means 5 or the closing means 2c, makes air enter the housing volume 2a, bringing said housing volume 2a and consequently the operating chamber 3a and sub-chambers 6a, if any, to the ambient pressure.

In detail, this action causes expansion of the inner wrapper 3 enabling the resistant elements 4b to become disgregated, i.e. the distinct particles 4 to stop compression; since said particles are again able to be mutually moved, they cause separation of the resistant elements 4a and allow object 10 to be extracted through the orifice 2b.

The invention enables important advantages to be reached.

A first advantage consists in that the deformable protective support or wrapper 1 allows an object 10 to be protected irrespective of its shape.

In fact, the inner wrapper 3 is characterised by high deformability and elasticity, enabling it to adhere to any object 10 in an almost perfect manner. This advantage is further obtained due to the fact that the inner wrapper 3 in the compressed configuration has an almost smooth contact surface with the object 10.

This aspect is obtained by virtue of the particular volume of the distinct particles 4 in the inner wrapper 3 enabling said wrapper 3 to be tensioned, when the object 10 is housed in the deformable support 1 , irrespective of the sizes of the object itself. In fact, introduction of object 10 into the support 1 causes elongation of the inner wrapper 3, as above described, so that said inner wrapper becomes taut and has a substantially smooth surface. Due to this advantage, the deformable support 1 can be also used for protecting parts of a human body such as an arm or leg, for example. In fact, as the inner wrapper 3 defines an almost smooth contact surface, a high sensation of comfort is ensured to the user. Another advantage is represented by the high construction simplicity of the deformable support 1 . In fact, housing of the distinct particles 4 inside an operating chamber 3a exclusively made up of the inner wrapper 3 allows both the distinct particles 4 to be placed in a simpler manner inside said chamber and the inner wrapper 2 to be fastened to the outer one 3 without complicated operations being carried out.

A further advantage is due to the great degree of protection ensured by the high strength offered by the resistant element 4a. This advantage is the result of the fact that compression of the distinct particles 4 is due both to the vacuum present within the housing volume 2a and to the above described return tensions exerting a further compacting force on the distinct particles 4. In fact, these return tensions tend to counteract elongation of the inner wrapper so that the distinct particles 4 are made more compact and further pressed together.

This protection is further due to the above described almost perfect adhesion between object 10 and inner wrapper 3 allowing the resistant element to adhere to the object 0 in an optimal manner and therefore protect said object in an ideal manner.

Another advantage is represented by the selection of the matenais the outer wrapper 2 is made of, which materials enable the object 10 to be isolated from external agents. In detail, these materials allow the contents of the deformable support 1 , i.e. object 10, to be isolated from the external environment, so that it is made immune to water, sudden temperature changes and moisture.

In detail, this aspect together with the high ability to absorb impacts and falls belonging to the supporting device 1 , enables deterioration of the portion of object 10 contained therein to be avoided so that an object can be preserved in a very safe manner over a particularly long period of time.

Another important advantage is given by the high adaptability of support 1 to the object shape. This advantage is due to the particular material used for manufacturing the inner wrapper 3 that ensures high deformability of the support 1 and therefore very high adaptability of the inner wrapper 3, and consequently of the resistant element 4a, to the shape of the object 10, or of an arm of other portion of a human body to be protected.

A still further advantage is the possibility of having a plurality of sub-chambers 6a so that, in the compressed configuration, the deformable support 1 has several resistant elements 4a characterised by different thickness and sizes so as to protect also the most brittle and delicate parts of object 10 in an optimal manner.

Furthermore, the innovative division of the operating volume into several sub- volumes 5a also enables perfect adhesion of the resistant elements to the object 10 to be ensured, irrespective of the shape thereof.

A further advantages resulting from said almost perfect adhesion between resistant elements 6a and object 10 resides in that device 1 is able to protect any point of object 10 in an almost perfect manner and therefore to ensure a high protection degree, irrespective of the shape of said portion.
