Description

Title of the invention: Respiratory protection mask comprising a beverage ingestion unit with linear mobility, and assembly equipped with said mask

[0001] The present invention relates to a respiratory protection mask provided with a beverage ingestion unit.

[0002] Like many respiratory protection masks known from the prior art, the protection mask according to the invention includes a support unit generally comprising, - a base body which is applied fluid-tight to a user's face, and covers at least the mouth and nose, - a strapping system holding said basic body on the head of said user and - at least one filtration unit.

[0003] Generally considered, the or each filter unit can be releasably connected to the base body.

[0004] The respiratory protection mask allows the user to stay in an environment in which the ambient air contains, or may contain, at least one gas and / or particles harmful (harmful) to humans. Ambient air breathed by the user is filtered by the filter units before it is inhaled by the user. The base body prevents ambient air from bypassing said units and, as a result, the user from breathing unfiltered ambient air.

[0005] When the user is standing for an extended period of time in a space containing potentially harmful ambient air, it is frequently desired that said user be able to absorb liquid without having to leave the environment and without having to remove the protective mask. A mask allowing this is provided with a beverage ingestion unit.

[0006] Documents DE 10 2011 016 805 B4 and US 8 640 693 B2 describe a respiratory protection mask provided with a beverage ingestion unit allowing a user to absorb liquid without having to remove said mask. A connecting element, in the form of a beverage absorption tube, can be rotated relative to a fluid guide element rigidly connected to the support unit.

[0007] The object of the invention is to provide a respiratory protection mask which, provided with a support unit and a beverage ingestion unit, can be used in a more flexible manner than protective masks known in the prior art.

[0008] The respiratory protection mask according to the invention includes a support unit and a beverage ingestion unit, this mask characterized in that the beverage ingestion unit comprises: - a rigid fluid guiding element, - a mouthpiece and - a connecting element, knowing that said fluid guiding element is mechanically connected to said connecting element and mechanically to said mouthpiece, a structural component of the support unit being designed to be applied against the face of a user of said protective mask,

[0009] knowing that a container or bottle, intended to contain a liquid, is or can be releasably attached to said connecting element,

[0010] the fluid guiding element and the connecting element being designed to establish, in association, a fluid communication between the nozzle and a container attached to said connecting element,

[0011] it being specified that said beverage ingestion unit: - can be animated by linear movements with respect to the support unit, in two mutually opposite directions, and - can be transposed to a state of ingestion of liquids following a linear movement towards the support unit, and to a state of moving away following a linear movement away from said support unit, and it being specified that the tip can be positioned in the user's mouth in the state of ingestion of liquids, and that said tip and the mouth are distant from each other in the state of separation.

[0012] The respiratory protection mask according to the invention includes a support unit of a design such that a flexible structural component thereof, in particular a facial camouflage, can be applied against the face of a user of said protective mask. Ideally, as a general rule, the structural component of said support unit separates at least the nose and mouth of the user from the ambient air, more precisely with fluid tightness, with the exception of well-defined orifices to which a filtration unit or a source of breathing air can be connected at each time. Filtered ambient air reaches the nose and mouth of the user through said orifices. In general, a strapping system of the protective mask retains said structural component on the face of the user.

[0013] The respiratory protection mask according to the invention further includes a beverage ingestion unit allowing a user of the mask to absorb a liquid even while said mask is in place. A container intended for liquid, and in particular in the form of a beverage absorption bottle or gourd, can be attached to a connecting element of said ingestion unit, which is further provided with a rigid fluid guiding element and a mouthpiece. Said mouthpiece is designed to be placed in the mouth by the user of the protective mask.

[0014] The fluid guiding element and the connecting element are connected in series and are capable of establishing, in association, a fluid communication between the mouthpiece and a liquid container attached to said connecting element. A user of the respiratory protection mask can absorb liquid from said container and entirely using said fluid communication.

[0015] The invention makes it possible to attach a container containing liquid to the connecting element. A user of the respiratory protection mask can then draw off a liquid from said attached container without having to remove said mask. This is of particular importance when the user is performing physical work, as harmful (harmful) gases and / or particles then occur, or may occur, in the environment of said user. Thanks to the beverage ingestion unit, it is also not essential for the user to leave the potentially hazardous environment in order to be able to take in liquid.

[0016] According to the invention, the beverage ingestion unit can be moved relative to the support unit, namely linearly in two mutually opposite directions. A sufficiently large linear movement of the ingestion unit, towards the support unit, transposes said ingestion unit to a liquid ingestion state in which the mouthpiece can be positioned, in the user's mouth, so that he can absorb liquid from the aforementioned container. A sufficiently large linear movement of the ingestion unit, away from the support unit, transposes said ingestion unit to a distance state in which a distance is established between the mouthpiece and the mouth. In both states of said ingestion unit, the flexible structural component of said support unit remains adjacent to the user's face.

[0017] According to the invention, the beverage ingestion unit can be transposed to the liquid ingestion state and to the removal state. Consequently, it is not required that the user permanently keep the mouthpiece in the mouth, even if he does not wish to absorb any liquid. A user often perceives it as inconvenient to have to keep a mouthpiece in the mouth permanently.

[0018] According to the invention, the beverage ingestion unit can be transposed to the liquid ingestion state by performing a linear movement relative to the support unit. This feature frequently implies that said beverage ingestion unit can be handled in a particularly simple and intuitive manner. In In many cases, to switch the ingestion unit to the ingestion state, a user simply needs to move the ingestion unit towards their own face. It is not imperative to rotate the ingestion unit to be able to absorb a liquid when the respiratory protection mask is in place, nor is it required to use a tool for this purpose. The ingestion unit can also frequently be transposed to the ingestion state, with ease, when the user is wearing gloves. As a general rule, both a left-handed person and a right-handed person can easily switch the ingestion unit to the ingestion state.

[0019] According to the invention, a rigid fluid guiding element connects the connecting element to the mouthpiece. By "fluid guiding element" is meant a structural part capable of guiding a fluid along a path, the latter being pre-established by the structural organization and arrangement of said part. A rigid tube and a flexible hose are two examples of fluid guiding elements. Ideally, the structural part prevents the fluid from leaving said path.

[0020] Since the rigid fluid-guiding element connects the connecting element to the mouthpiece, it is not imperative to position, in the respiratory protection mask, a hose or any other flexible fluid-guiding element. Such a flexible structural part may remain stuck or bend and / or not reach the user's mouth.

[0021] In a preferred design according to the invention, a wrapping piece surrounds the fluid guide element, both when the beverage ingestion unit is in the liquid ingestion state and when said ingestion unit is in the removed state. The wrapping piece protects the fluid guide element, to a certain degree, against mechanical and chemical damage from the outside. In many cases, as a result, said guide element can be of an easier design compared to a design without a wrapping piece. This is mechanically connected to the support unit, on one side, and to the connecting element on the other side. The length, and therefore the dimensioning of said wrapping piece is variable along a longitudinal axis of said guide element.Possible forms of concrete arrangement of such a wrapping part are presented as a pleated pipe, a bellows and a telescopic pipe. Thanks to this feature, said part surrounds said guide element in both states of the beverage ingestion unit, without significantly hindering a linear movement of said unit with respect to the support unit.

[0022] In a concrete arrangement form according to the invention, the wrapping part is an elastic structural part or is designed as a structural part elastic, which has a state of rest. The beverage ingestion unit is in the state of separation when said elastic structural part, and therefore said wrapping part, is in the state of rest. A pivoting excursion of the latter, causing it to leave said state of rest, generates an elastic restoring force tending to return said wrapping part to said state of rest. To move the beverage ingestion unit to the state of ingestion of liquids, the latter is animated by a linear movement towards the support unit, in opposition to said restoring force.

[0023] The concrete form of arrangement in which the wrapping part comprises an elastic element having a rest state, or is of elastic design, provides in particular the advantage that, as a rule, a user hardly has to apply force, and hardly spend time to return the beverage ingestion unit to the removed state. On the other hand, it is generally sufficient to release said ingestion unit. The elastic restoring force developed by the wrapping part transposes, of itself, said ingestion unit to said removed state.

[0024] According to the invention, the beverage ingestion unit is provided with linear mobility relative to the support unit and, therefore, relative to the face of a user. In one design, a guide element is mechanically connected to the support unit and guides the ingestion unit, during a linear movement, to make it pass from one of the states to the other state. Said element guides the rigid fluid guide element and in particular includes a tube, preferably a rigid tube surrounding a segment of said fluid guide element, or even the entirety of the latter. This design reduces the risk of undesired occurrence, when a liquid container is attached to the connecting element, of a restriction or even an interruption of a fluid communication established between the mouthpiece and said container, due to the fact that the fluid guide element becomes kinked or slips.

[0025] The respiratory protection mask according to the invention includes a rigid fluid guiding element and a connecting element. In one design, said rigid fluid guiding element extends along a longitudinal axis designated as "longitudinal axis of the fluid guiding element". Said connecting element extends along a longitudinal axis designated as "longitudinal axis of the connecting element", an angle greater than zero being preferably formed between these two longitudinal axes, said angle being a right angle or an acute angle. This design facilitates the positioning of a container of liquid in front of a user's chest and below the longitudinal axis of the fluid guiding element. In many practical uses, therefore, said container is less disruptive that in a design in which said guide element and said connecting element are arranged collinearly.

[0026] In accordance with the invention, a container containing liquid can be attached to the connecting element, preferably in a releasable manner. In a concrete form of arrangement, said connecting element can be rotated relative to the fluid guide element, about the longitudinal axis thereof. In this way, an attached liquid container can also rotate about this longitudinal axis. This design further increases the flexibility of use during the practical use and implementation of the respiratory protection mask according to the invention. Due to this concrete form of arrangement, in particular, a user can more easily hold an attached liquid container with the help of, as desired, the left hand, the right hand or both hands, causing a corresponding orientation and positioning of the connecting element.

[0027] In a design according to the invention, a non-return valve is integrated into the connecting element, and has a rest state in which said valve closes said connecting element with fluid tightness relative to the surrounding space. Therefore, when said valve is in the closed state, neither harmful gases nor particles can reach the face of a user of the respiratory protection mask by traveling, from one side to the other, through the connecting element. Said valve can be opened in opposition to an elastic restoring force developed by an elastic element. In the open state of said valve, the user can absorb liquid from an attached container.

[0028] In a practical use, the check valve opens, in opposition to the elastic return force, when a vacuum occurs in the end of the connecting element facing the fluid guide element. This vacuum is generally generated by a user sucking liquid. In another practical use, said valve opens, in opposition to the return force applied to it, when an overpressure occurs in the end of said connecting element facing an attached liquid container. This overpressure may, for example, result from the fact that said container is compressed, or even that an overpressure develops in said container. Another design, also possible, consists in that, when the liquid container is attached to the connecting element, a projection located on said container opens the check valve in opposition to said elastic return force.

[0029] It is also possible for a rigid element to be capable of opening the non-return valve, which rigid element is preferably in fluid communication, or even optionally, in mechanical connection with a liquid container attached to the connection element. The rigid element opens said non-return valve in opposition to the restoring force when said container, and consequently also said rigid element, are attached to said connecting element. In many cases, said valve can be opened, using this rigid element, more easily than by generating a vacuum or an overpressure. When use is made of such a rigid element, an additional advantage lies in the fact that the elastic force restoring the valve can be greater, in many cases, so that said valve is closed with greater reliability.

[0030] Preferably, the support unit comprises at least one retaining system pierced with an opening. A respective filtration unit can be removably connected to the system, or to each retaining system, for example using a screw connection, a bayonet closure or a snap closure. Said opening establishes a fluid communication between an environment of the respiratory protection mask and an interior space reserved between said support unit and the face of a user. The removably connection allows the replacement of a filtration unit. The system, or each retaining system and the beverage ingestion unit are preferably separated by a lateral distance, so that a filtration unit can be replaced also when said mask is in place, and said ingestion unit does not prevent this replacement.Conversely, said filtration unit does not hinder in any way, or only in a negligible way, the use of said ingestion unit.

[0031] The invention further relates to an assembly including - a respiratory protection mask in accordance with the invention, according to the design equipped with the non-return valve, - a container or bottle intended to contain a liquid, and - a preferably rigid fluid guidance unit.

[0032] The fluid guide unit is connected to the liquid container, in a fixed or releasable manner, thereby establishing a fluid communication between said container and said guide unit provided with an orifice and insertable into the connecting element. Once said guide unit is inserted into said connecting element, the non-return valve is in the open state, or assumes this state. Said connecting element surrounds a segment of said guide unit, and said orifice accordingly. A fluid communication is then established between the liquid container and the mouthpiece of the respiratory protection mask, which fluid communication leads to the interior space of said connecting element through said orifice.

[0033] The invention is described below with the support of an exemplary embodiment, with reference to the appended drawings in which:

[0037] [Fig.4] is a cross-section of a beverage ingestion unit provided with a check valve ;

[0038] [Fig.5] shows how a canister can be attached to the ingestion unit of drinks; and

[0039] [Fig.6] is a cross-section of a biting mouthpiece, assigned to said unit of ingestion.

[0040] [Fig.l] illustrates a respiratory protection mask 100 as known in the prior art. Said protective mask 100 comprises a base body 2, a sealed containment part 5 and a two-part strapping system 1.1, 1.2. The part 5 is connected to the base body 2 in a fluid-tight manner. A retaining system 3.1 located on the left and a retaining system 3.r located on the right are fixed to said body 2, the two systems 3.1 and 3.r each having the form of a screw connection or a bayonet closure, or even a snap closure. A respective filter unit 4.1, 4.r can be releasably inserted into said two systems 3.1 and 3.r.

[0041] When a user B wears the respiratory protection mask 100, the sealed containment part 5 is placed in front of the mouth and nose of said user B, ideally with fluid tightness, the strapping system 1.1, 1.2 being pressed against the neck, and holding said part 5 in front of the mouth and in front of the nose. A discharge valve 6 is housed in the body 2 and is located in front of the mouth of user B. Exhaled air flows through said discharge valve 6.

[0042] The invention allows the user B to absorb liquid without having to remove the respiratory protection mask 100. The mask 100 according to the invention includes, for this purpose, a unit 10 for ingestion of beverages. A bottle or container F1 of another type can be attached to this unit 10, knowing that said container F1 contains a liquid and that the user B can suck the latter through said ingestion unit, or bring it to the mouth in another way, for example by compressing said bottle F1.

[0043] [Fig. 2] is a perspective, observed obliquely from the right, showing the respiratory protection mask 100 according to the invention, placed in front of the nose and mouth of the user B. [Fig. 3] is a cross-section of said mask of [Fig. 2]. In the latter, a shutter 7.r is installed on the retention system 3.r located on the right as a substitute for the filtration unit 4.r. A corresponding shutter 7.1, not visible, is located on the left side.

[0044] The beverage ingestion unit 10 is attached to the base body and comprises - a mouthpiece 14, - a fluid guiding element 13, in the form of a rigid tube, - a tubular and rigid guide element 15, - a wrapping piece appearing as a bellows 11 and - a connecting element 12 whose longitudinal axis is designated by LA.a, and which is connected to said bellows 11 with fluid tightness.

[0045] The mouthpiece 14 is fixed, in a fluid-tight manner, to the end of the tubing 13 which points towards the user's mouth, which tubing 13 establishes a fluid communication between said mouthpiece 14 and the connecting element 12. The guide element 15, connected to the base body 2 with a rotary lock and in a fluid-tight manner, surrounds a segment of said tubing 13.

[0046] The bellows 11 connected, in a fluid-tight manner, both to the base body 2 and to the connecting element 12, completely and concentrically surrounds the tubing 13 in the exemplary embodiment.

[0047] The wrapping piece 11, the tube 13 and the guide element 15 extend along a common longitudinal axis LA.f. The extent of the rigid tube 13 along the longitudinal axis LA.f is invariable, while the extent of the wrapping piece 11 can vary along said axis LA.f. Because said piece 11 is of variable length, linear movements can be imparted to the connecting element 12 with respect to the base body 2, namely in two mutually opposite directions, parallel to the axis LA.f, which two directions are indicated by a double-headed arrow Br in [Fig. 3]. The guide element 15 guides the tube 13 during a movement taking place parallel to said axis LA.f, and prevents tilting or twisting of said tube 13.In the concrete arrangement form illustrated, the guide element 15 limits a movement of said tubing 13 away from the mouth of the user B, more precisely because the mouthpiece 14 comes to abut, from the inside, against said element 15.

[0048] In the embodiment, the connecting element 12 is connected to the tubing 13 with a rotary lock, the mouthpiece 14 being similarly connected to said tubing 13 with a rotary lock. In a concrete form of arrangement, said element 12, said tubing 13 and said mouthpiece 14 can be driven by a joint rotation, about an axis of rotation DA, with respect to the base body 2 and with respect to the guide element 15. In a concrete form of arrangement, the bellows 11 is endowed with sufficient elasticity to undergo reversible torsion by itself. In another concrete form of arrangement, the tubing 13 can rotate relative to said bellows 11, which bellows 11 nevertheless surrounds said tubing 13 with fluid tightness at each location taken by rotation. The axis of rotation DA coincides with the longitudinal axis LA.f in the exemplary embodiment. Said axis DA, and therefore said axis LA.f, are arranged horizontally when the gaze of user B is directed horizontally forward.

[0049] Thanks to the presence of the bellows 11, it is possible to modify the distance between the connecting element 12 and the container F1, on the one hand, and the mouth of the user B on the other hand. Figures 2 and 3 show said bellows 11 in a rest state. A distance separates the mouth of the user B from the mouthpiece 14 when said bellows 11 is in the rest state. The beverage ingestion unit 10 is then in a remote state.

[0050] In order for user B to drink from the container F1 attached to the connecting element 12, the beverage ingestion unit 10 is moved towards the mouth of said user B in a direction parallel to the longitudinal axis LA.f, until the mouthpiece 14 reaches the mouth and said user B can take and drink liquid from said container F1. As a general rule, user B can himself grasp the element 12 and move it towards his face, thereby imparting a linear movement to said ingestion unit 10. This can also, however, be carried out by another person. Said unit 10 is in a liquid ingestion state when user B can encircle the mouthpiece 14 with his mouth.

[0051] The bellows 11 is retracted on itself in the case where the beverage ingestion unit 10 is moved towards the face of the user B. The retracted bellows 11 develops, in the manner of an elastic element, an elastic return force tending to return said bellows 11 to the rest state and, consequently, to move the ingestion unit 10 away from the face of the user B and to move it towards the moving away state. As a result, no action by the user B is required to maintain a spacing between the mouthpiece 14 and the mouth. On the other hand, the bellows 11 brings said unit 10 to the moving away state by itself and maintains it in this state. Said bellows 11 surrounds the tubing 13, both in the liquid ingestion state and in the moving away state.

[0052] In the case where no bottle F1 is attached to the connecting element 12, no air from the environment must reach the user B by passing through said element 12 and the tubing 13. It is possible to hermetically close said element 12 by means of a shutter. [Fig. 4] schematically illustrates another, or additional, design, having the following effect: when the respiratory protection mask 100 is in the remote state, air emanating from the surrounding space is prevented from reaching the user B by passing through the connecting element 12 and this, more precisely also, when no liquid container F1 is attached to said element 12.

[0053] In one design, a non-return valve 20 is integrated in the connecting element 12. This non-return valve 20, on the one hand, is closed in a rest state and, on the other hand, closes, in said rest state, said connecting element 12 with fluid tightness with respect to the surrounding space. This non-return valve 20 is designed in such a way that, on the one hand, it applies a restoring force during a pivoting excursion from the rest state and can be opened in opposition to the restoring force and, on the other hand, it allows, at the open location, a fluid communication between said connecting element 12 and said surrounding space. [Fig. 4] shows a concrete arrangement form of this valve 20.

[0054] In the embodiment shown, an adapter 27 is releasably attached to the free end of the connecting element 12, for example by means of a screw closure. This adapter 27 surrounds, in a fluid-tight manner, a neck of an end piece 30 which is the subject of a description below. Said free end of the element 12 is further surrounded by a sealing ring 24.

[0055] The non-return valve 20 comprises - a spherical shutter body 21, - a closure seat 22, - a pressure spring 23 and - a movable element 25 for coming into contact with the stop.

[0056] The closure seat 22 is shaped internally on the connection element 12. The pressure spring 23 bears on the tube 13 and tends to press the closure body 21 against said closure seat 22, and thus to close the non-return valve 20. The movable element 25 for coming into abutment is rigidly connected to said body 21, which body 21 can be moved away from the seat 22, in opposition to the force of said spring 23, until said element 25 comes to rest against a fixedly mounted stop element 26. Said stop element 26 is rigidly connected to said tube 13.

[0057] In one design, user B draws liquid from bottle F1 or compresses said bottle F1, which causes the non-return valve 20 to open.

[0058] [Fig. 5] shows another possible design of how a liquid container F1 can be attached to the connecting element 12. This other design allows the pressure spring 23 to develop a higher elastic force, and thus to close the non-return valve 20 with greater safety. It is not imperative that the user B opens said non-return valve 20 by suction. A fluid guide unit 32 is connected to the liquid container F1 in a fluid-tight manner. Said guide unit 32 comprises the rigid end piece 30 pierced with an orifice O, and a flexible pipe 31 which is connected to said container F1 in a fixed or releasable manner and is fixedly connected to said end piece 30, in a fluid-tight manner. Said rigid part 30, which can be inserted into the internal space of the connecting element 12, is provided with a rigid plate 33 pointing towards the shutter body 21.The orifice O is located at a distance from said rigid plate 33.

[0059] When the end piece 30 is introduced into the connecting element 12, said end piece 30 moves the shutter body 21 in opposition to the return force of the spring 23. In the situation illustrated in [Fig. 5], this plate 33 is applied against the body 21, but the non-return valve 20 nevertheless remains closed. Said valve 20 is open when the end piece 30 is pushed further inside the connecting element 12, the orifice O then being surrounded by said element 12. The user B can then absorb, from the container F1, liquid flowing through the fluid guide unit 32, the orifice O and the beverage ingestion unit 10.
