Definitions

  • the subject of the invention is a training and / or snorkel mask with improved air flow according to the preamble of claim 1.
  • a training mask of this type is, for example, with the subject matter of WO 2017/214645 A1 known. It is a breathing mask with a mask body that covers the mouth and nose and has a frontal air inlet and a frontal air outlet which is also provided with a check valve.
  • the air inlet comprises a rotary slide valve in a receptacle which has at least one air inlet opening which partially encloses the central air outlet, the rotary slide valve covering the air inlet opening differently depending on its rotary position and thus a throttling of the air inlet opening Breathing air is possible.
  • the supply air is throttled in order to generate a stronger inhalation resistance in order to train the muscles in the chest of a person associated with inhalation and exhalation.
  • the disadvantage of the known training mask is that the airways in the training mask, i.e. the supply air and the exhaust air, are not separated from each other, which means that the expelled breath, which is enriched with CO 2, is partially sucked in again in an unintended and disadvantageous manner which reduces the oxygen content of the air we breathe.
  • the invention is therefore based on the object of developing a training or snorkeling mask of the type mentioned at the beginning in such a way that an improved air flow is present.
  • the exhaled air combines with the inhaled air and, in the manner of a short circuit, deteriorates the inhaled air with regard to the oxygen content.
  • the invention is characterized by the features of claim 1 as applicable.
  • the invention accordingly relates to a training mask for training the respiratory muscles and / or a snorkel mask with improved air guidance of the inhaled and exhaled air consisting of a half-mask sealing the mouth and nose area, with a half-mask in front of the half-mask and the area of the mask that is sealed off from the user air-guiding, hollow-profiled channel connector is arranged, via which at least the inhaled air can be introduced into the half-mask frontally via an approximately central inflow opening.
  • This solution also serves to improve the air flow of the snorkel mask, because the exhalation resistance for blowing out the exhaled air is reduced because of the shortened length of the blow-out paths.
  • All four versions have the feature of improved air conduction in common, which consists in the fact that the inhaled air is routed separately from the exhaled air and that the inhaled air is guided directly and is directed frontally into the mouth and nose opening without significant flow obstacles. This means that there are no major deflections and flow-increasing flow paths for the inhaled air.
  • the air flow is also improved by optimizing the flow paths for the exhaled air.
  • a snorkel mask that is not equipped with an air-throttling rotary slide can also achieve a training effect during swimming training, because the air channels in the interior of the snorkel mask, due to the design, produce a throttling of the inhaled and / or exhaled air and thus the desired training effect of the respiratory muscles.
  • An advantageous feature of the invention is that the exhaled air is no longer - as in the WO 2017/214645 A1 is expelled at the front of the half mask, but the exhaled air is expelled laterally at least on one side of the half mask in a forced air flow - either directly via valve-supported side exhaust openings or into the blowout paths of the snorkel - so that the front inhalation flow and the side exhalation flow do not conflict be able to cross and mix more.
  • the half mask used has two diametrically opposite, lateral outflow openings that are directed into the outside atmosphere, so that the exhaled stream flows laterally from the half mask over the side of the person's face and the inhaled stream from the front is directed into the half mask.
  • it is a central and frontal air inlet which is arranged in the front area of the half mask and behind which a large-area closure valve is arranged in the half mask, which only allows inhalation, but closes it during exhalation.
  • valves there are two diametrically opposite, lateral blow-out openings which are also closed off by valves, with all valve devices preferably being designed as smooth-running poppet valves with flexible membranes.
  • valves arranged in the area of the outlet openings therefore only open under the action of the exhaust air, but close when the air is sucked in via the front valve.
  • a turntable which was connected to a rotary valve as part of a reducing device, was used to partially or completely close the air intake openings in order to throttle the air intake.
  • a different air duct is used because the fresh air is sucked into the half mask through a large, front-side inhalation valve.
  • this large-area poppet valve is closed and the exhaled air then only goes through the side vent openings that are closed again when you inhale.
  • the invention claims a further embodiment in which the inhalation and exhalation paths are lengthened by at least one snorkel.
  • a training mask therefore also serves as a snorkel mask and is intended to enable breathing training while swimming.
  • This exemplary embodiment thus differs from the previously mentioned exemplary embodiment of a training mask in that the first exemplary embodiment has a half mask in which the input and Exhalation paths are fluidically separated from one another and are not guided into one another in an air-tight manner.
  • the second exemplary embodiment differs from the first exemplary embodiment in that the inhalation and exhalation paths in a snorkel mask are guided through one or two snorkels.
  • the aim is to achieve the same training effect as with a training mask.
  • a particular advantage of the invention in a special embodiment is that the swimmer is now able for the first time to inhale and exhale with his nose, which was previously not possible. Until now, only mouth breathing was possible.
  • the advantage of the second embodiment according to the invention is therefore that a training mask expanded by one or two snorkels in its training as Snorkel mask can now also be used in water, because it is particularly important for swimmers to achieve additional, targeted training of the respiratory muscles while exercising.
  • the training mask according to the invention allows inhalation through the nose, because the inhaled air is preheated and filtered through the nasal inhalation and is therefore inhaled into the lungs in a conditioned state, which was not previously known.
  • the basic concept of the training mask is now transferred to a snorkel mask in which the inlet air opening can be closed and opened in a controlled manner in the same way and in which there is also a strict separation between the inhalation and the exhalation flow and in addition nasal breathing is possible.
  • the invention does not rely on the arrangement of a rotary slide that turns the snorkel mask into a training mask, but it is sufficient to omit the rotary slide completely and still use the snorkel mask as a training mask because of the design-related over The relatively narrow air ducts such a training effect can be expected.
  • a snorkel mask can also be used as a training mask, and with this snorkel mask, which dispenses with an air slide, absolutely separate guidance of the inhaled and exhaled air is guaranteed. This was not the case with the prior art.
  • the invention provides in a further development that the profile space on the nose side of the half mask is designed to be elastically bendable and it is now possible for the first time to access the half mask at least in the nose area and to press the nostrils together in order to achieve pressure equalization under water.
  • This option is provided for both a land-based training mask and a water-based snorkel mask.
  • Exhalation takes place with valve support via channels arranged on the edge of the visor and the face seal, which allow the exhaled air to be blown out again into a channel in the snorkel that is separate from the inhaled air.
  • valve-supported outlet openings for blowing out the exhaled air can be arranged in the duct connector, which is thus blown directly into the water and no longer has to be guided over the snorkel via the long flow paths in the edge area of the snorkel mask. This significantly reduces the exhalation resistance.
  • One or more valve-supported blow-out openings can be provided.
  • the one or more blow-out openings can be arranged directly on the front in the center of the duct connector.
  • the outlet openings can each be arranged laterally on the channel connector.
  • the one or more valve-supported blow-out openings can be arranged at the bottom - in the middle or at the side - on the duct connector
  • the snorkel mask according to the invention therefore also allows pressure compensation in the interior of the snorkel mask by means of a pressure compensation valve arranged in the half mask, which allows the air blown with pressure from the lungs through the mouth into the half mask via the transfer openings assigned to the inhaled air the interior of the snorkel mask is pressed in in order to counteract the water pressure which acts on the snorkel mask from the outside at greater diving depths and presses the snorkel mask in an undesirable manner against the head of the wearer.
  • the training mask 8 has a front cap 51, which is present for design reasons and covers the half mask 8 towards the front, the recess for the inflow opening 22 into the half mask 8 being provided in the front cap 51.
  • a headband 24 is also shown with which the training mask 1 can be attached to the head.
  • FIG. 1 shows the Figure 2 already has a training mask 1, which has a half mask 8, which is preferably made of a flexible, compressible plastic material, e.g. B. a polyurethane or a comparable plastic material.
  • a half mask 8 which is preferably made of a flexible, compressible plastic material, e.g. B. a polyurethane or a comparable plastic material.
  • the half mask 8 sealingly encloses the face and nose area of the wearer and is provided with head straps 24 (not shown in detail) (see FIG Fig. 1 ) attached to the head of the wearer so that inhalation and exhalation can only take place via the interior space 12 of the half-mask 8.
  • each snorkel having at least one supply air channel 4 and at least one exhaust air channel 5 separated therefrom.
  • the inhaled air is sucked in the direction of arrow 6 into the air inlet duct 4 of the snorkel 3 and arrives in the direction of the arrow 10 into a connecting part 15, which also connects the opposite supply air duct 4 in the snorkel 2 in an air-tight manner, so that supply air from both snorkels 2, 3 and the supply air ducts 4 arranged there with a high cross-section leads into the connecting part and there into an inflow opening 22 which is arranged frontally on the front side 16 of the half mask 8.
  • the connecting part 15 is also referred to later as a channel connector 40. Both parts 15, 40 have the same task, namely to enable the inhalation and exhalation paths to be separated in the area in front of the half mask 8. When using the connecting part 15 or the channel connector 40 in both cases, this leads to the particular advantage that the inhaled air can be fed from the front into the mouth area of the half-mask 8.
  • a poppet valve (not shown in more detail) (also described later in the design as a reducing device 50), which is designed over a large area in order to enable a large-volume inflow of inhaled air via the front inflow opening 22.
  • the exhaled air is no longer blown out via the front-side inflow opening 22, as is known in the prior art, but that now lateral blow-out openings 14 are arranged on the half mask 8, through which the blown air flows into the Exhaust openings 14 arranged valves in the direction of arrow 13 flows out laterally. It then reaches the exhaust air duct 5 arranged on both sides and flows out of the two snorkels 2, 3 in the direction of the arrow 7.
  • valve-supported blow-out openings 14 can lead directly into the environment, which means that the exhaled air reaches the water directly via the valve-supported blow-out openings 14.
  • the inhaled air is guided through the air inlet channel 4 of the snorkel 2, 3. In this way, the exhaled air is no longer guided into the exhaust air duct 5 of the snorkel 2, 3, but instead is fed directly into the water, shortening the flow path.
  • this snorkel mask is used as a training mask, the exhaled air is blown out into the surrounding air.
  • FIG 3 shows a representation similar to Figure 2 , only with the difference that the half mask 8 is also integrated in a visor 17, which encloses the entire face in a sealing manner and a snorkel mask 1a is formed from it, which extends from the half mask 8 to the Figures 1 and 2 differs only slightly.
  • a snorkel mask 1 a is therefore suitable as a training mask 1 both for dry training outside of the water and for swimming training.
  • rotary slide valve the handle 25 of which is shown in FIG Figure 1 is shown, can also be omitted because an air-throttling training effect is given in snorkel masks 1a, 1b even without a rotary valve.
  • the snorkel mask 1a shows in FIG Figure 3 a visor 17, which is transparent, and the two snorkels 2, 3 are provided, which each form separate supply air and exhaust air ducts 4, 5.
  • the supply air flows in the direction of arrow 10 into the interior of the visor 17 and keeps it fog-free.
  • the supply air flows into the half-mask 8 via the channels 15, 31, 40, 62 to be described later and is absorbed by the mouth and nose of the user, which has the advantage that with such an arrangement both oral and nasal breathing is possible.
  • the inhaled air passes through the interior of the visor in the direction of the arrow 10 into lateral transfer openings 20 arranged in the intermediate area between the visor 17 and the half mask 8, where it flows into the inlet area of the connecting part 15 on both sides in the direction of arrow 10 and into the frontal inflow opening 22 the half mask 8 arrives.
  • the exhaust air passes through the exhaust openings 14 arranged on the side of the half mask 8 - completely separate from the inhaled air - into the respective exhaust air duct 5 in the respective snorkel 2, 3 - or alternatively via valve-supported exhaust openings 14 directly into the environment (water or air) - so that separate air ducts are also available here.
  • the supply air thus flows via the supply air duct 4 in the direction of arrow 6 into the interior of the visor 17 and then flows - as on the basis of FIG Figure 3 explained - via the in Figure 4 Transfer openings 20 (not shown) in the front channel connector 40, which is designed here as a connecting part 15, the connecting part 15 being closed off in the direction of the blow-out channel by a closure 19 in order to avoid mixing of inhaled and exhaled air.
  • the exhaled air flows in the direction of the arrow 13 through the exhaust openings 14 arranged laterally in the half mask 8 into an air duct 23 arranged laterally in the snorkel mask 1a, 1b, which can either be integrated into the snorkel mask on the edge of the face seal or also run as a separate channel in the snorkel mask can be.
  • blow-out air duct which is routed as an internal air duct in the interior of the snorkel mask 1a, 1b as a separate air hose.
  • FIGS. 3 and 4 show that the air supply via either two snorkels 2, 3 ( Figure 3 ) or via a single snorkel 3 ( Figure 4 ).
  • the Figure 5 shows an inside view of a snorkel mask 1b, which is designed as a training mask in such a way that the general inventive concept is implemented for all embodiments, namely an improved air guidance of the inhaled and exhaled air.
  • the inhaled air flows from the snorkel 3 into the interior of the mask, ie over the inside of the visor 17 and flows in the direction of arrow 10 into associated transfer openings 20, which are integrated in the mask frame 30 of the snorkel mask 1b, so that it is ensured that the inhaled air over large cross-sections in the channel connector 40 arranged in front of the half mask 8 and connected to it, in the direction of the central inflow opening 22.
  • the blow-out openings 9 are separated from the blow-in opening 22 and are directed laterally outwards in order to avoid mixing of inhaled and exhaled air.
  • the invention provides two different exemplary embodiments with regard to the snorkel mask according to FIG. 1b.
  • exhaust openings 9 and the transfer openings 20 are closed with suitable poppet valves in order to achieve forced inhalation when the exhalation openings are closed and, conversely, a closure of the inhalation openings when the exhalation opening blows out exhaust air.
  • valves can be omitted in the area of the transfer openings 20, 22 because the separation of the airways is built into the snorkel, i. H. via the valve device 25 at the end of the snorkel.
  • the snorkel 2, 3 then only carries either inhaled air or exhaled air, so that the valve-related openings 20, 22 in the snorkel mask 1b itself can be dispensed with.
  • the valves can therefore be relocated into the snorkel.
  • the inhaled air flows in the direction of arrow 10 over the inside of the visor 17 and keeps it fog-free.
  • the exhaled air is directed from the blow-out openings 9 into the frame-side exhaust air ducts 5 and from there into the exhaust air duct 5 in the respective snorkel 2, 3.
  • FIG 6 shows schematically the structure of a snorkel mask 1b according to Figure 5 , where it can be seen that a total of three essential parts are present, namely a visor 17 which is sealingly inserted into the mask frame 30 and also a half mask 8 which is connected to a face seal 29, the face seal 29 being inserted in a sealed manner in the mask frame 30 .

  • FIG Figure 26 shows a graphic representation of lateral in the duct connector 40 arranged exhaust openings 64, so that the exhaust air ducts 5 can be omitted and valve-supported lateral blow-out openings 64 are instead arranged in the duct connector 40 through which the exhaled air can reach the environment.
  • the exhaust openings 64 (in Figure 6 and 26th ) are valve-supported in order to prevent water from entering the half mask 8 through the outlet opening 64 in an undesired manner when the expiratory flow is blown out into the water.
  • blow-out openings 9 in the half mask 8 are connected to the lateral, valve-supported blow-out openings 64 in the channel connector 40 in an air-tight manner.

  • FIG 8 shows schematically the routing of the inhaled air in the duct connector 40, which, however, is only indicated schematically, where it can be seen that the inhaled air flows in the direction of arrow 10 into the lateral transfer openings 20 and there via tubular or cavity-shaped connecting pieces 31 is introduced into the middle, frontal inflow opening 22 of the half mask 8 in the direction of arrow 38 on both sides.
  • the duct connector 40 which is large in terms of flow technology, has only a slight flow diversion and uses large flow cross-sections, which result from the large volume of the connecting pieces 31, 62.
  • the inhaled air is comparatively guided in the direction of arrow 10 directly from above onto the nose, which requires that the inhaled air must still be deflected at the bridge of the nose of the user in order to get into the nostrils, while in the present case the inhaled air directly from the front is introduced into the mouth area at the front of the half mask 8 via the central inflow opening 22, as a result of which there are significantly lower flow resistances.

  • FIG 18 shows the guidance of the exhaust air compared to Figure 17 , where it can be seen that the blow-out openings 9 are arranged in the duct connector 40, in the interior of which the blow-out air is conducted separately from the inhaled air into peripheral connection openings 32, which are air-locked with the adjoining exhaust air ducts 5.
  • snorkel masks 1a, 1b which are suitable for swimming training
  • a reducing device 50 can also be arranged in such snorkel masks 1, 1a, 1b, as it is based on the later Figures 19-25 is explained.
  • a reducing device 50 corresponding to the following figures is installed in a snorkel mask 1, 1a, 1b according to the previously described implementation methods, for example in the area of the inflow opening 22 of the half mask 8.
  • the invention therefore also claims this particular embodiment to be preferred.
  • Figure 19 shows a training mask for dry training, the way it is in Figure 1 was shown.
  • the training mask 1 shown has a half mask 8 which surrounds the mouth and nose area of the user and the previously described outlet openings 9 are present on the sides of the half mask, which in the embodiment shown are closed by a poppet valve 48 so that only the outlet air comes out there but no inhalation air can enter.
  • the front side of the half mask 8 is formed by a reducing device 50 with which the supply of inhaled air can be reduced, the Reducing device consists essentially of a web part 49 fixed to the housing, on which a large-sized poppet valve 47 is arranged in the area of a pivot bearing 52, which ensures that only inhaled air can enter via the central air inlet opening 22, but no blown air can exit there.
  • the reducing device 50 is also formed by a rotary slide 26 which is approximately disk-shaped and is rotatably mounted in a rotary bearing 52, the rotary slide having a handle 25 on one side for its rotary actuation.
  • the front side of the reducing device 50 is covered by a front cap 51 in which a multiplicity of through-flow openings 53 are arranged.
  • the Figure 20 shows the use of the training mask Figure 19 for swimming training, where at least one snorkel 3, 18 can be used, in which two separate channels 4, 5 are arranged for the supply air and exhaust air, because the supply air is air-locked in the direction of arrow 10 with the front of the half mask 8 and the exhaust air via the blow-out openings 9 arranged laterally on the half mask 8, overcoming the poppet valve 48 arranged there, reaches the blow-out duct in the direction of arrow 13.
  • This system can also be used without the mentioned reducing device 50 and offers the swimmer the advantage that he can also breathe through his nose without having to rely on the operation of the reducing device 50.
  • the reducing device 50 can work with a rotary valve 26 and additionally with a filter 60 placed in front of it, or even only in Unique if the rotary slide valve 26 is omitted and only one filter 60 is present.
  • the Figure 21 shows in deviation from Figure 20 that it is not necessary for the solution to let the expiratory flow blow out through the snorkel 3, 18 itself.
  • the Figure 21 shows therefore that the blow-out openings 9, which are used for the blow-out air and which are closed off by a poppet valve 48, can discharge the blow-out flow in the direction of arrow 55 directly into the environment.
  • Such an arrangement is also suitable for both dry training and swimming training.
  • the Figure 22 shows a schematic plan view of the reducing device 50, where it can be seen that there are a plurality of throughflow openings 53 evenly distributed around the circumference in the fixed web part 49, which can also be closed by valve-leaf or wing-like closure cross-sections of the rotary slide 26. Depending on the rotational position of the locking rotary slide 26, more or less closed flow openings 53 result for the breathing air.
  • the rotary slide 26 has a radially outwardly directed, resiliently designed latching hook 56 which can be brought into engagement in associated latching recesses 57 fixed to the housing in order to fix a certain latching position of the rotary slide 26.
  • FIG. 12 shows a filter which can either be inserted into the reducer 50 or which can be used in place of the rotary valve 26.
  • FIG. 12 shows a filter which can either be inserted into the reducer 50 or which can be used in place of the rotary valve 26.
  • the half mask 8 extends in a sealed manner over the nose and mouth of the user in order to enable combined mouth and nasal breathing.
  • a reduced half mask can only extend over the mouth area and the nostrils are closed by a conventional nose clip, so that in this case a training mask is only available for mouth breathing.
  • the Figure 26 shows - compared to Figure 6 - Another embodiment of the blowing out of the exhaled air via blow-out openings 64 drawn there.
  • the mask frame 30 carries a front cover 63.
  • exhaust openings 64 in the duct connector 40 do not must necessarily be arranged in a channel connector 40. They can be arranged directly on or in the mask frame 30 or on or in the visor 17 in order to ensure that instead of guiding the exhaled air through long blow-out channels 5 into the snorkel 2, 3, it is now ensured that the exhaled air from the half mask 8 can be blown out in the direction of arrow 65 directly into blow-out openings 64 arranged laterally on the mask frame 30.
  • the valve-supported blow-out openings 64 are arranged laterally on the mask frame and / or on the visor 17.
  • one or more blow-out openings 64 can be arranged at the bottom and in the center of the visor 17 and / or on the mask frame.
  • the advantage of the training mask 1, 1a, 1b according to the various exemplary embodiments is that it has a simple design with direct flow paths and that it can optionally be designed as a dry training mask or as a wet training mask (snorkel mask). A crossing and mixing of the inhaled and exhaled air in the area in front of the half mask 8 is avoided in all versions.
  • the inhalation air is supplied from the front, frontally, into the mouth area of the user, and therefore there is the possibility of creating a snorkel mask or training mask that is suitable for both dry training and swimming training.
