Definitions

  • the invention relates to an inflatable buoyancy aid for assisting swimming learning, e.g. can be worn on both upper arms of a person.
  • a buoyancy aid or a water wings gives a user in the water the necessary buoyancy to familiarize themselves with the water environment under supervision and to learn the necessary swimming movements.
  • Simple versions of inflatable buoyancy aids are known in the form of swimming cuffs, which are equipped with two air chambers. They are preferably used to give to infants and young children the necessary buoyancy, which should enable them to stay safely in the water where they can no longer stand.
  • the learning of swimming movements is possible with this known design of swimming cuffs.
  • the constant buoyancy of the bicameral Wegmanschetten is disadvantageous. If now the buoyancy of the floating collars should be reduced, for example, the air could be drained from a chamber. Releasing aliquots of air from a chamber also loosens the tight bond with the upper arm, which can cause the cuff to shift to a learner-threatening position on the forearm, or even become completely stripped.
  • the buoyancy aid has a band connectable by means of Velcro to a ring on which an air chamber is attached. The filling state of the air chamber influences the seat of the buoyancy aid on the arm.
  • the buoyancy aid has two annular air chambers arranged concentrically to the arm.
  • the air chambers are formed of a flexible material, which is processed by means of a weld into a closed ring.
  • the US 3,727,252 discloses a floating ring attachable to an upper arm.
  • An embodiment of such a floating ring comprises two annular air chambers arranged conzentrically to the upper arm.
  • the GB 2 108 053 A shows a bracelet for a float, which is produced by welding two sheets of plastic material.
  • the bracelet has in the arm longitudinal direction side by side arranged air chambers.
  • an inflatable arm floating ring which has three arm longitudinally juxtaposed air chambers, which are connected to a non-inflatable portion to form a ring.
  • the object of the invention is to provide a buoyancy aid that can be easily fixed to a body part and their buoyancy can be varied without loosening the fixation.
  • a buoyancy aid according to the invention for assisting swimming learning in a liquid can be slipped over an arm in a partially or deflated condition and fixed in an at least partially inflated state on the arm and has an annular member, at least one inflatable fixation chamber and at least one inflatable one An additional chamber, wherein the at least one fixation chamber and the at least one additional chamber are arranged on the annular element and wherein the buoyancy aid can be fixed in an at least partially inflated state of at least one fixation chamber on an arm.
  • the buoyancy aid can be fixed with its inside on the arm or be applied to the arm or rest.
  • An annular element may e.g. an annular element or a circulating belt to which the at least one inflatable fixation chamber and / or the at least one inflatable additional chamber are attached. Further, only one fixation chamber or additional chamber may be attached to the annular member, with the other chamber being attached to the fixation chamber or auxiliary chamber. Further, the band may be configured to form a permanent closed ring. In another embodiment, a band can be connected to a releasably connected ring, wherein the required for solvability fasteners may be, for example, a hook and loop fastener, buttons, a zipper or other fasteners.
  • the annular element may further form the at least one fixation chamber and / or the at least one additional chamber, for example a wall of such a chamber.
  • the ring is formed by a plurality of band-shaped superimposed layers of a gas-tight, preferably thermoplastic film, which is welded at its longitudinal sides, so that in each case a cavity is formed between the layers of the films. It can be understood by the annular element and the wall which limits a chamber.
  • the at least one inflatable fixation chamber will be filled with gas depending on the thickness of the arm and, depending on how firm the buoyancy aid is to be fixed to the arm Seat or buoyancy aid on the arm is guaranteed.
  • the fixation of the buoyancy aid on the arm is preferably frictionally engaged, wherein the strength of the frictional fixation of or, for example, depends only on the filling state of the fixation chamber.
  • the fixation chamber is at least partially inflated so much that the buoyancy aid in normal swimming movements, so at normal loads, does not slip from their fixed to the arm area. This can be assisted, for example, by the area adjacent to the arm being provided with an anti-slip surface. It is also possible that the surface applied to the arm is designed skin-breathable and / or gentle to the skin.
  • the at least one inflatable fixation chamber may be formed by chambers disposed on or in the annular member. This also implies that the fixation chamber is formed by the annular member by providing a multilayered material for the annular member. At least one inflatable additional chamber is located on the annular element, wherein the additional chamber can also be arranged on the fixation chamber. Likewise, the fixation chamber can be arranged on the additional chamber.
  • a fixation chamber can be connected to at least one further fixation chamber via an overflow element, so that a gas exchange can take place between the fixation chambers connected in this way.
  • a Chamber connected via an overflow with another chamber. This further chamber is again connected via an overflow element with a next new chamber, etc.
  • a chamber is connected via a plurality of overflow with other fixation chambers.
  • all fixation chambers may preferably be connected to one another by at least one overflow element, so that a gas exchange can take place between the fixation chambers connected in this way.
  • at least one overflow element can be provided so that, for example, two chambers can be connected to a plurality of overflow elements.
  • fixation chambers can form a fixation chamber system, wherein at least one valve is provided for inflating the fixation chamber system for each fixation chamber system.
  • a valve for inflating may be provided for each non-gas exchangeable fixation chamber.
  • a valve for inflation may be provided, for example, by a plug valve with a check device.
  • the valve is pressed into the air space after inflation, so that a risk of scratching or injury, which would emanate from a protruding valve, is minimized.
  • any valve is suitable that allows the supply and the intentional discharge of gas into and out of the chamber, but prevents unwanted discharge of gas from the chamber.
  • fixation chambers apply equally to the arrangement and connection of one or more additional chambers.
  • the filling state of the additional chamber (s) does not influence the filling state of the at least one fixation chamber, so that the fixation of the buoyancy aid to the arm is essentially independent of the degree of filling of the additional chamber (s).
  • additional chamber and fixation chamber such as additional chamber system and Fixationsschsystem, no connections to each other, so that each consist of separate chamber systems.
  • the at least partially inflated fixation chambers ensure a tight fit on the arm, regardless of whether the additional chambers are filled with gas or not, since the filling state of the additional chambers do not affect the fixation chamber or fixation chamber system.
  • the additional chambers are preferably arranged on the buoyancy aid or buoyancy aid so that the interior of the buoyancy aid available for insertion of an arm is not or only insignificantly influenced by the filling state of the additional chambers and preferably only by the filling state of the fixation chamber (s).
  • the additional chambers may be arranged on an outer side of the buoyancy aid, so that, for example, the fixation chamber is located between the arm and the additional chamber.
  • the additional chamber may preferably not or only slightly rest on the arm, regardless of the filling state of the fixation chamber, so that the fixation or the strength of the frictional engagement formed between buoyancy aid and arm is substantially independent of the filling state of the additional chamber.
  • the buoyancy aid may be slid over the arm and fixed in an inflated state on the arm to aid in swimming learning in a liquid in a partially inflated or deflated condition.
  • the buoyancy aid may comprise two flank members joined together to form a closed ring through which the arm may be passed, the at least one inflatable fixation chamber formed by at least one flank member of the two flank members, the at least one fixation chamber the buoyancy aid in the inflated state can fix on the arm, and comprise at least one inflatable additional chamber, which is formed by at least one flank element, wherein the buoyancy of the buoyancy aid in the liquid can be adjusted with the degree of filling of the at least one additional chamber.
  • a fixation chamber can also be used as an additional chamber and vice versa, eg in the case of a symmetrical arrangement of the chambers.
  • each flank member is formed by a fixation chamber and an additional chamber. It is also conceivable that the fixation chamber and the additional chamber are formed by the flank element.
  • the two flank elements can be connected on one side with a web element.
  • the web element contains neither a fixation chamber nor an additional chamber.
  • the web element is preferably carried by the user of the buoyancy aid on the underside of the upper arm, so that the upper arm can be applied laterally to the chest of the person due to the small thickness of the bar element without a disturbing distance being formed by a fixation chamber or an additional chamber ,
  • fixation chambers of the one flank element could be connected in a gas exchangeable manner with fixation chambers of the second flank element, wherein the connection could be realized via an overflow element in the flank element.
  • fixation chambers of the one flank element could be connected in a gas exchangeable manner with fixation chambers of the second flank element, wherein the connection could be realized via an overflow element in the flank element.
  • the flank elements are preferably connected directly to one another on the side of the annular buoyancy aid opposite the web element.
  • This connection could be realized both solvable and insoluble.
  • the connection is in a weld.
  • the overflow element for chambers of one flank element is located in chambers of the other flank element in the region of the side which is opposite to the web element.
  • the overflow element may be a specially provided component, which is incorporated in the buoyancy aid, e.g. a hose or similar molding.
  • the overflow is formed by an interruption in the weld, so that gas from one chamber of the one flank member can flow into the chamber of the other flank member.
  • several overflow elements can connect the chambers.
  • the two edge elements have the same number and type of chambers.
  • one chamber of the one flank element is connected in pairs to the chamber of the other flank element in a gas exchangeable manner.

  • the chambers are arranged in a row arranged approximately radially to the arm longitudinal direction.
  • each flank element can be applied to the arm chamber, the fixation chamber and the other, arranged behind it, the additional chamber.
  • the buoyancy aid is applied to an arm, a fixation chamber of the buoyancy aid is at least partially inflated to apply the buoyancy aid firmly to the arm and an additional chamber of the buoyancy aid is not or at least partially inflated to the buoyancy to adjust the buoyancy aid.
  • the buoyancy aid according to the invention and the method of attaching a buoyancy aid allow the buoyancy force to be reduced by controlling the air volume in a portion of the chambers in a controlled manner as the buoyancy progresses, without the firm adjustment of the buoyancy aid to the upper arm to relax the other part of the chambers.
  • the valve can be pulled out of an air chamber and acted with the stopper open as long as the check device until the desired amount of air has escaped. Due to the uniform distribution of the buoyancy force for further controlled reduction of the amount of air, the process is preferably carried out according to the other chamber of the corresponding air chamber pair.
  • the deflation of the air to reduce the buoyancy takes place uniformly on both sides of the cuff, wherein only one valve per chamber system is necessary.
  • the air chambers are preferably mounted on the same side of the device.
  • the inflatable buoyancy aids are preferably made of a gas-tight thermoplastic film.
  • a sheet of soft PVC e.g. in multi-layered design, which is welded for shaping by high-frequency welding.
  • all other plastic materials having the same characteristics mentioned above, e.g. Polyurethane or copolymers of metallocene-catalyzed polyolefins, also suitable.
  • the welding can also be carried out with other advantageous methods which utilize the effect of the thermoplastic deformation. For example, a pulse, hot air, ultrasonic or friction welding method can be used. It would also be conceivable to use coated film webs or films of elastomeric materials which have to be vulcanized for shaping.
  • the inflatable buoyancy aid can be made by stacking a number of plastic films cut into strips. The longitudinal sides of the superimposed films are welded together with a suitable method, so that each forms a tubular volume between two films.
  • This multi-chambered film tube is cut to a length that is slightly larger than the unwound length of the inflatable buoyancy aid. Approximately in the middle of the cut-to-length film tube, the over- and underside and the intervening films are welded almost over their entire width. To form an overflow element, a small gap across the width is not welded. Spaced on both sides in the longitudinal direction of said weld, the entire film joint is welded together over its entire width. The distance of the two outer welds from the inner weld corresponds to the length of the flank elements.
  • the foil joint is bent at an acute angle both around its middle weld seam, as well as around the two outer welds, and the two each between one Front side and an outer weld formed areas superimposed and put together.
  • One of the areas between the central weld and the outer weld is provided with a number of valves corresponding to that of the formed chambers or chamber systems in a flank member, preferably each valve being connected to a different chamber.
  • Fig. 1 shows an inflatable buoyancy sleeve, which is formed from a total of four chambers 10a, 10b, 11a, 1b.
  • the buoyancy sleeve consists essentially of an annular element 1; 2, which consists in this case of the web element 1 and the partitions 2.

  • fixation chambers 10a, b and additional chambers 11a, b are limited at the rear and front end of the buoyancy aid by a weld, not shown. No gas exchange takes place between the fixation chambers 10a, b and the additional chambers 11a, b.
  • a fixation chamber 10 and an additional chamber 11 together form a flank element.
  • the two fixation chambers 10a, b of both flank members are arranged in pairs, which means that the number of fixation chambers 10 in each flank member is the same.
  • the fixation chambers 10a and 10b are connected to one another via an overflow element 8a connected gas exchangeable. Thus, it is possible that gas from one fixation chamber 10a can flow into the other fixation chamber 10b and vice versa.
  • the interconnected fixation chambers 10a and 10b together form a fixation chamber system 10.
  • the fixation chamber system 10 is connected to a valve 6a, through which gas can be introduced into the fixation chamber system 10 and removed therefrom.

  • the partition wall 2 By running over the full width of the buoyancy aid weld 7 no gas from a fixation chamber 10 or an additional chamber 11 in the occur between the layers 2, 3, 4 of the stem member 1 formed volume, so that the web element 1 has substantially a small height in contrast to the edge elements.
  • Fig. 2 shows a plan view of the buoyancy aid and in particular the overflow 8a or 8b in detail.
  • the overflow element 8 is formed by at least one gap in the weld seam 5.
  • the inner wall 3 has been joined to the outer wall 4 and the separating wall 2 in a substantially gas-tight manner so that a gas exchange within the fixation chamber system 10 and within the additional chamber system 11 in the region of the weld seams 5 can not take place.
