Definitions

  • the invention relates to a training or snorkeling mask with improved airflow according to the preamble of patent claim 1.
  • a training mask of this type is, for example, the subject of WO 2017/214645 A1 known. It is a breathing mask with a mask body covering the mouth and nose, which has a frontal air inlet and a frontal air outlet with a non-return valve.
  • the air inlet include a rotary slide in a receptacle that has at least one air inlet opening that partially encloses the central air outlet, with the rotary slide covering the air inlet opening differently depending on its rotary position and thus throttling the breathing air is possible.
  • the disadvantage of the known training mask is that the airways in the training mask, ie the supply air and the exhaust air, are not separated from one another, which means that the expelled breathing air, which is enriched with CO 2 , is also partially sucked in again in an unintentional and disadvantageous manner , thereby reducing the oxygen content of the inhaled air.
  • the invention is therefore based on the object of further developing a training or snorkeling mask of the type mentioned at the outset in such a way that there is improved air guidance.
  • the exhaled air combines with the inhaled air and the inhaled air deteriorates in terms of the oxygen content in the manner of a short circuit.
  • the invention is characterized by the features of claim 1 as it applies.
  • the invention therefore relates to a training mask for training the respiratory muscles and/or a snorkeling mask with improved airflow for the inhaled and exhaled air, consisting of a half mask that seals off the mouth and nose area, with the half mask and the area of the mask sealed off from the user being air-carrying, hollow-profiled duct connector is arranged, via which at least the inhaled air can be introduced frontally via an approximately central inflow opening into the half-mask.
  • This solution also serves to improve the air flow of the snorkel mask, because the exhalation resistance to exhaling the exhaled air is reduced due to the shortened length of the exhalation paths.
  • All four designs have the feature of an improved air flow in common, which consists in the fact that the inhaled air is guided separately from the exhaled air and that the inhaled air takes a direct path and is fed frontally into the mouth and nose without any significant obstacles to the flow. This means that there are no significant deflections and flow-enhancing 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-restricting rotary slide can also achieve a training effect during swimming training, because the air ducts routed inside the snorkel mask create 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 expelled at the front of the half mask, but the exhaled air is expelled at least on one side of the half mask laterally in a forced air flow - either directly via valve-supported lateral exhaust openings or into the exhaust paths of the snorkel - so that the frontal inhalation flow and the lateral exhalation flow do not mix be able to cross and mix more.
  • the half mask used has two lateral outflow openings diametrically opposite one another, which are directed into the outside atmosphere, so that the exhaled flow flows laterally from the half mask over the lateral parts of the person's face and the inhaled flow flows frontally from the front directed into the half mask.
  • a central and frontal intake air opening 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 during exhalation.
  • valves there are two diametrically opposed, 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 located in the area of the outlet openings therefore only open under the influence of the exhaust air, but close when the air is sucked in via the front valve.
  • a turntable connected to a rotary valve as part of a reducing device was used to partially or fully close the inlet air openings in order to throttle the inlet air.
  • a different air flow is used because the fresh air is sucked into the half-mask through a large-sized, front-side inhalation valve.
  • this large poppet valve is closed and the exhaled air then only goes through the lateral vent openings, which 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.
  • the inflow and exhaust openings in the half mask are valve-free and the associated valves are relocated into one or more snorkels
  • this exemplary embodiment 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 airtight manner.
  • the second exemplary embodiment also differs from the first exemplary embodiment in that the inhalation and exhalation paths in a snorkel mask are routed through one or two snorkels. However, the same training effect as with a training mask is sought.
  • a particular advantage of the invention is, in a special embodiment, 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.
  • Advantage of the second embodiment of the invention is therefore that an extended training mask by one or two snorkels in their training as Snorkeling mask can now also be used in the 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 by nasal breathing 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 snorkeling mask in which the air inlet 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 exhalation flow and additionally nasal breathing is possible.
  • the invention is not dependent on the arrangement of a rotary slide, which 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 due to the design-related, over the relatively narrowly dimensioned air ducts such a training effect is to be expected.
  • a snorkel mask can also be used as a training mask, and this snorkel mask, which does not have an air slide, ensures that the inhalation and exhalation air are guided completely separately. This was not the case with the prior art.
  • the invention provides in a further development that the nose-side profile space of the half mask is designed to be elastically flexible 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 possibility is provided for both a land-based training mask and a water-based snorkel mask.
  • the exhalation is valve-supported 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 channel connector, which is thus blown out directly into the water and no longer has to be routed 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-assisted exhaust ports may be provided.
  • the one or more exhaust openings can be arranged directly on the front in the center of the duct connector.
  • the outlet openings can each be arranged on the side of the channel connector.
  • the one or more valve-supported blow-out openings can be arranged at the bottom—centrally or laterally—on the duct connector
  • the snorkel mask according to the invention therefore also allows pressure equalization in the interior of the snorkel mask by means of a pressure equalization valve arranged in the half mask, which allows the air blown out under pressure from the lungs via the mouth into the half mask via the transfer openings assigned to the inhaled air into is pressed into the interior of the snorkel mask in order to counteract the water pressure that acts on the snorkel mask from the outside at greater diving depths and presses the snorkel mask against the head of the wearer in an undesired manner.
  • the training mask 8 carries a front cap 51 which is present for design reasons and which covers the half mask 8 to the front, with the recess for the inflow opening 22 in 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.
  • inflow opening 22 arranged behind the through-flow openings 53 in the front cap 51 is only shown schematically because the actual inlet is arranged behind the through-flow openings 53 in the front cap 51 in the half-mask 8 .
  • a training mask 1 which comprises a half-mask 8, which preferably consists 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 equipped with head straps 24 (not shown in detail). 1 ) attached to the wearer's head, so that inhalation and exhalation can only take place via the interior 12 of the half mask 8 .
  • each snorkel having at least one inlet air duct 4 and at least one exhaust air duct 5 separated therefrom.
  • figure 2 also the use of a single snorkel 2 or 3 as in figure 25 is shown.
  • the inhaled air is sucked in the direction of the arrow 6 into the inlet air duct 4 of the snorkel 3 and arrives in the direction of the arrow 10 into a connecting part 15, which also air-tightly connects the opposite supply air duct 4 in the snorkel 2, so that supply air from the two snorkels 2, 3 and the supply air ducts 4 arranged there is introduced with a high cross-section into the connecting part and is guided 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 later also referred to as a duct connector 40 .
  • Both parts 15, 40 have the same task, namely to enable a separation of the inhalation and exhalation paths in the area in front of the half mask 8.
  • Behind the inflow opening 22 is a not-shown poppet valve (also described later in the design as a reducing device 50), which has a large surface area in order to allow a large-volume inflow of inhaled air via the front-side 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 lateral exhaust openings 14 are now arranged on the half mask 8, through which the exhaust air can flow into the Blow-out 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 intake air duct 4 of the snorkel 2, 3.
  • the exhaled air is no longer guided in the exhaust air duct 5 of the snorkel 2, 3, but is guided directly into the water, shortening the flow path.

  • a snorkel mask 1a is therefore suitable as a training mask 1 both for dry training outside of the water and for swimming training.
  • rotary valve the handle of which is 25 in figure 1 is shown, can also be omitted because an air-throttling training effect is given with snorkel masks 1a, 1b even without a rotary slide.

  • the supply air flows via the channels 15, 31, 40, 62 to be described later into the half-mask 8 and is absorbed by the user's mouth and nose, which has the advantage that such an arrangement allows both mouth and nose breathing is possible.
  • the inhaled air passes through the interior of the visor in the direction of arrow 10 shown into lateral transfer openings 20 arranged in the intermediate area between the visor 17 and the half mask 8, where it flows in on both sides into the input area of the connecting part 15 in the direction of arrow 10 and into the frontal inflow opening 22 the half mask 8 arrives.
  • the exhaust air reaches the respective exhaust air channel 5 in the respective snorkel 2, 3 via the exhaust openings 14 arranged on the side of the half mask 8 - completely separate from the inhaled air - or alternatively via valve-supported exhaust openings 14 directly into the environment (water or air) - so that separate air ducts are also available here.
  • FIG figure 4 shows another form of snorkeling mask 1b, which differs from snorkeling mask 1a according to FIG figure 3 differs in that a single snorkel is present, which defines the separate supply air and exhaust air ducts 4, 5. Otherwise, the same description applies as to figure 2 and 3 .
  • 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 shown in FIG figure 3 explained - about the in figure 4 transfer openings 20, not shown, into 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 exhaust channel by a closure 19 in order to prevent inhalation and exhalation air from mixing.

  • the figure 17 shows the routing of the exhaled air via the lateral exhaust openings 9 arranged in the half mask 8, which is introduced into the lateral exhaust air ducts 5 in the manner previously described via air-conducting ducts in the duct connector 40 and connection openings 32.
  • the figure 18 shows the routing 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 guided separately from the inhaled air into peripheral connection openings 32, which are air-tightly connected to the exhaust air ducts 5 adjoining them.
  • snorkeling masks 1a, 1b which are suitable for swimming training
  • a reducing device 50 arranged on them, as will be explained using 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 embodiments, 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, among other things.
  • figure 19 shows a training mask for dry training, of the kind shown in figure 1 was shown.
  • the training mask 1 shown therefore 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 side of the half-mask, which are closed by a poppet valve 48 in the exemplary embodiment shown, so that only the outlet air exits there , but no inhaled air can enter.
  • the front of the half mask 8 is formed by a reducing device 50, with which a supply of inhaled air can be reduced, the
  • the reducing device essentially consists of a web part 49 fixed to the housing, on which a large-sized poppet valve 47 is arranged in the area of a rotary bearing 52, which ensures that only inhaled air can enter via the central air inlet opening 22, but no blown-out 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 its 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 flow openings 53 are arranged.
  • the figure 20 shows the application of the training mask figure 19 for swimming training, whereby at least one snorkel 3, 18 can be used, in which two separate channels 4, 5 for the supply air and exhaust air are arranged, because the supply air is airtightly connected in the direction of arrow 10 to the front of the half mask 8 and the exhaust air via the blow-out openings 9 arranged on the side of the half-mask 8 reach the blow-out channel in the direction of the arrow 13 by overcoming the poppet valve 48 arranged there.
  • This system can also be used without said reducing device 50 and offers the swimmer the advantage that he also has nasal breathing without having to rely on the actuation 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 only in Unique position when the rotary valve 26 is omitted and only one filter 60 is present.
  • the figure 21 shows in deviation to figure 20 that it is not necessary for the solution to let the exhaled flow blow out through the snorkel 3, 18 itself.
  • the figure 21 therefore shows that the exhaust air serving exhaust openings 9, which are closed by a poppet valve 48, the exhaust flow in the direction of arrow 55 can be discharged directly into the environment.
  • Such an arrangement is also suitable both for dry training and for swimming training.
  • the figure 22 shows a schematic plan view of the reducing device 50, where it can be seen that there are a large number of flow openings 53 distributed evenly around the circumference in the fixed web part 49, which can also be closed by valve-reed 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 locking hook 56 which can be brought into engagement with associated locking recesses 57 fixed to the housing in order to fix a specific locking position of the rotary slide 26 in this way.
  • FIG. 12 shows a filter that can either be inserted into the reducer 50 or that can be used in place of the rotary valve 26.
  • FIG. 12 shows a filter that can either be inserted into the reducer 50 or that can be used in place of the rotary valve 26.
  • FIG. 24 and 25 a training mask 1 each for swimming training, with only the interior of the half mask 8 being airtightly connected to the snorkels 2, 3 described above for the swimming training, and thus separate routing of the inhaled and exhaled air in the inlet and outlet air ducts 4, 5 of the snorkel 2, 3 via the channel connector 15, 40 described.
  • the half mask 8 extends sealingly over the user's nose and mouth to allow combined mouth and nose 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 provided for mouth breathing.
  • the figure 26 shows - compared to figure 6 - Another embodiment of blowing out the exhaled air via the blow-out openings 64 shown there.
  • the mask frame 30 carries a front cover 63.
  • exhaust openings 64 in the channel connector 40 shows the figure 26 that such exhaust openings 64 are not necessarily have to 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 exhaust channels 5 into the snorkel 2, 3, the exhaled air can now flow 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 exhaust openings 64 are arranged on the side of the mask frame and/or on the visor 17 .
  • one or more exhaust openings 64 can be arranged at the bottom and in the middle on 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 there is a simple construction with direct flow paths and that it can be designed as a dry training mask or as a wet training mask (snorkel mask). Crossing and mixing of the inhaled and exhaled air in the area in front of the half mask 8 is avoided in all designs.
  • the inhalation air is supplied from the front, frontally into the user's mouth area and therefore there is the possibility of creating a snorkel mask or training mask which is suitable for dry training as well as for swim training.
