Definitions

  • the invention relates to a fitness training aid, and in particular to an aid comprising a mass to be lifted and gripped to enable training exercises to be performed.
  • Various types of fitness training aids are known, such as kettlebells, dumb-bells, weight bars or similar. These known aids, which allow users to perform a multitude of exercises to train different muscles of the body, have intrinsic limitations, however, due to their shape. In particular, these aids generally comprise a rigid or substantially rigid body, with a center of gravity that is fixed with respect to the geometry of the body. The load of these aids is therefore described as stable.
  • Patent application WO 2005/075026 A1 describes a training aid comprising a flexible jacket or bag that can be partially filled with a liquid or with loose solid particles. The remaining empty volume of the bag may be filled with compressed air so as to make the outer form defined and stable.
  • the liquid inside the bag moves continuously, at different speeds depending on the movements of the athlete.
  • the movement of the liquid therefore generates a continuous variation in the aid's center of gravity that is often sudden and not foreseeable by the athlete.
  • this aid does not make it possible to control the movement of the liquid inside the bag, for example between opposing walls.
  • the excessively fast movement of the liquid can generate recoil due to the inertia generated by the impact of the liquid against the internal walls of the bag.
  • the object of the present invention is to propose a training aid that solves the problems of the prior art described above.
  • the aim of the present invention is therefore to propose a training aid that can provide an instable load that is controlled at least in part.
  • Another aim of the present invention is to propose a training aid that makes it possible to control the degree of instability following movements of the aid in different directions.
  • a further aim of the present invention is to provide a training aid that makes it possible to vary the total load, or mass, in a simple and practical manner.
  • a further aim of the present invention is to provide a training aid that is economical and simple to manufacture.
  • a training aid comprising: a flexible, impermeable membrane defining a chamber that can be filled at least in part with a liquid; at least one opening on said membrane, associated with closing means for sealing the chamber once said liquid has been inserted; and at least one handle for grasping the aid and performing a training exercise.
  • the chamber is occupied partly by the liquid, for example water, and the remaining part by a gas, for example air.
  • the gas is inserted into the chamber at a pressure higher than atmospheric pressure so as to stretch the membrane and give the aid its final shape for use.
  • the chamber comprises at least two compartments in fluid communication with one another and at least one partial wall separating said compartments yet allowing the passage of liquid.
  • the function of the wall is therefore to regulate the flow of liquid from one compartment of the chamber to another. This makes it possible to limit the inertial force that the aid discharges onto the person performing the exercise in the event of abrupt variations in the direction and/or sense of movement.
  • At least one portion of the perimeter of said wall is attached to the inner surface of the membrane.
  • the perimeter of the wall may therefore have a shape substantially the same as the cross-section of the membrane at the point where it is attached, or it may have a different shape.
  • the passage of the liquid may also occur in noncontact zones between the wall and the inner surface of the membrane.
  • on the surface of the wall there are one or more openings that act as a passage for the liquid between the compartments.
  • said openings may have a substantially circular perimeter. In fact, this shape makes it possible to uniformly distribute the force of tension generated by the thrust of the moving fluid.
  • the openings have the same passage area to allow a homogeneous flow of liquid between the compartments regardless of the position of the aid and of the way in which it is grasped by the user.
  • the openings may be distributed on the surface of the wall in a pattern having at least one axis of symmetry and preferably at least two axes of symmetry.
  • the aid may comprise two or more walls substantially parallel to one another. These walls therefore define a plurality of compartments next to one another.
  • This implementation is particularly effective when the aid has an elongated tubular shape, for example cylindrical.
  • the effects of inertia and recoil can be felt more when the liquid moves along the axis of the tubular element.
  • the walls can therefore be placed next to one another along said axis of the tubular element.
  • the aid may comprise at least two walls intersecting with one another.
  • each compartment is in communication with at least two other adjacent compartments.
  • This implementation is more effective when the chamber has a more regular shape, for example spherical, parallelepiped or substantially cubical.
  • the ratio P between the area of passage of the fluid and the surface area occupied by the wall, between two adjoining compartments is preferably between 0.5 and 3 and more preferably between 0.7 and 2. More precisely, this ratio relates to the free surface for the passage of fluid with respect to the surface occupied by the wall material. As this value increases, the passages have a greater area, therefore allowing a more rapid flow of liquid.
  • the ratio P may be the same for all parallel walls next to one another along the same direction.
  • the training aid may comprise reinforcing strips on the outer surface of the membrane.
  • said strips are placed in the zone where the wall is connected to the internal surface of the membrane.
  • the membrane in said zones therefore has less flexibility, enabling it not to deform as a result of the forces exerted on it by the walls when they in turn are struck by the moving liquid.
  • said reinforcing strips can act as a support for connecting gripping means to the training aid.
  • the training aid indicated as a whole by the number 10 comprises a membrane 11 delimiting or defining a chamber 12 on the inside of the membrane.
  • the membrane 11 is body having a wall that is made of a material impermeable to fluids.
  • the membrane is made of a flexible material, such as a plastic.
  • the membrane may be formed of polyvinyl chloride (PVC), polyurethane (TPU), synthetic rubber (CSM), chlorosulfonated polyethylene (CPSE), other polymeric materials or combinations thereof.
  • the membrane 11 can be formed as a rigid, non-flexible body.
  • the chamber 12 can be filled at least in part with a liquid L or small particles.
  • the liquid can be water or other liquids with a similar viscosity. In other implementations, the liquid can have a higher viscosity and/or density than water.
  • the small particles can be sand, or beads, pellets, balls, flakes, and/or pieces formed of a plastic material, a metal, a polyurethane, stone, glass, an elastomeric material, a thermoset material, and combinations thereof.
  • the aid 10 can include a re-closable opening 13 to enable the liquid, the small particles, or combinations thereof to be added or removed from the chamber 12 of the membrane 11.
  • the remaining volume of the chamber 12 is filled with a gas G, for example compressed air.
  • the gas may be ambient air, nitrogen or combinations thereof.
  • the opening 13 is associated with a closure 14 positionable between a closed position and at least one open position. When closed, the closure 14 assists in sealing the chamber 12. When opened, the liquid or particles can be added to or removed from the chamber 12.
  • the closure 14 is configured to be reclose-able so as to be opened and closed so as to allow the chamber to be filled or emptied several times.
  • the closure 14 can also be used to allow pressurized gas to be inserted into the chamber.
  • the closure 14 can be first and second spaced apart closures with the first closure configured for the adding or removal of the liquid or particles, and the second closure configured for adding or releasing gas into the chamber 12.
  • the membrane 11 is formed of a flexible material and can be shaped in such a way that, once the chamber 13 has been filled and sealed, the training aid takes on a specific shape for use. In the implementations illustrated in FIGS.
  • the training aid can have, for example, an elongated tubular shape, more precisely a cylindrical shape.
  • the aid 10 can be formed in other shapes, such as, for example, spherical, hemispherical, irregular, generally polygonal or combinations thereof.
  • the membrane 11 is shaped in such a way that, once the chamber 12 has been filled and sealed, the training aid takes on a specific shape for use.
  • the training aid 10 has, for example, an elongated tubular shape, more precisely a cylindrical shape.
  • the tension of the membrane 11, and therefore the stiffness of the training aid 10 can be regulated by increasing or decreasing the pressure of the gas in the chamber 12.
  • the chamber 12 comprises at least two compartments in fluid communication with one another.
  • the chamber 12 comprises three compartments 12a, 12b, 12c, with the compartments separated by one or more walls 15 having one or more openings 16 to allow the liquid L to flow from one compartment 12a, 12b or 12c to an adjoining compartment 12a, 12b or 12c.
  • the aid 10 may include 3, 4, 5 or more walls to defining 3, 4, 5 or more compartments.
  • the wall 15 serves to limit the speed with which the fluid moves between the ends of the chamber, especially when the aid is moved quickly.
  • the wall 15 comprises a lamina, the perimeter 15a of which is connected to the inner surface 11 a of the membrane 11.
  • the lamina or wall 15 may be made of the same material as the membrane 11 or in another material.
  • the wall 15 or lamina can be thicker than the membrane 11 so as to have less flexibility and to give the aid greater stability when in use.
  • the lamina may be substantially rigid.
  • Suitable materials for the wall 15 include, for example, polycarbonate, polyethylene (PE), polyvinyl chloride (PVC), polypropylene, polymethylmethacrylate (PMMA). Polycarbonate, other polymeric materials or combinations thereof.
  • the one or more openings 16 in the wall 15 enable the liquid to pass through the opening from one of the chambers 12, 12b or 12c to another of the chambers 12a, 12b or 12c.
  • the openings 16 act as passages for the transfer of the liquid L between compartments.
  • the size, number, and or position of the openings 16 in the wall 15 enable the flow of the liquid or particles to be controlled or governed.
  • the total area of the openings with respect to the cross-section of the aid at the point where the wall is attached determines the speed at which the liquid can flow from one compartment of the chamber to another.
  • the number of openings 16 and their size is chosen based on the damping effect one wishes to achieve on the liquid L inside the chamber 12.
  • each wall 15 defines a fluid passageway area that is composed of the collective area of the one or more openings 16 in the wall 15 or the porosity or permeability of the wall 15.
  • the fluid passageway ratio of the wall is the fluid passageway area over the surface area occupied by the wall 15.
  • the fluid passageway ratio is within the range of 0.5 and 3.
  • the fluid passageway ratio is within the range of 0.7 and 2.
  • the openings 16, preferably, are circular in shape so as to avoid forces being concentrated on the edge of the openings, which could cause lacerations to the lamina.
  • the openings can be form of other shapes such as polygonal, oval, irregular, or combinations thereof.
  • said openings 16 are distributed on the surface of the wall in such a way that the passage of the fluid is homogeneous and independent of the orientation of the aid in space.
  • the openings 16 are arranged in a circular series around the axis of the tubular body.
  • the wall 15 may be connected to the inner surface of the membrane only by one part of its perimeter. The passage of liquid may therefore be in the space between the wall and the inner surface of the membrane 11.
  • the wall may also comprise several separate laminas connected independently to the inner surface 11 a of the membrane 11.
  • the wall 15 may comprise a permeable, fibrous, natural or synthetic fabric. In this case also, by adopting a more or less permeable fabric, it is possible to vary the speed at which the liquid passes through the wall 15 to move from one compartment to another adjacent compartment.
  • the wall may be formed partially of a permeable material and partially of a non-permeable material with or without openings.
  • the chamber 12 may be provided with several walls 15.
  • the walls 15 are arranged next to one another along the axis of the tubular body and parallel to one another. In his way, the damping effect on the inertia of the liquid is felt when the movement of the liquid L inside the chamber 12 takes place in a direction substantially parallel to the axis of the tubular body.
  • the aid can include one or more handles or gripping members.
  • said strips are placed on the membrane in the zone where the walls 15 are connected to the inner surface 11 a. The function of the strips is to make the membrane less deformable underneath as a result of the forces exerted on it by the walls when they are struck by the moving liquid.
  • the training aid according to the invention is provided with gripping members 18, such as handles or similar, for example, so that the aid can be grasped and moved when performing training exercises.
  • the gripping members 18 can be a pair of spaced-apart handles to facilitate the grasping and maneuvering of the aid 10.
  • FIG. 3 illustrates another implementation of the fitness training aid 10.
  • the chamber 11 can be provided with two spaced-apart transversely extending walls 15 within the chamber 12, and a third wall 15 longitudinally extending between the first and second spaced apart walls 15.
  • the walls 15 can substantially perpendicular to one another.
  • the training aid configured in such a way makes it possible to dampen the inertia of the liquid L when it moves around the chamber 12, in different directions. Starting from this implementation, it is possible to vary the number of walls 15, arranging them partly parallel and partly transversal to one another. In other implementations, other numbers of walls or configurations of walls can be used to provide different properties, flow-rates, etc. of the liquid or particles within the membrane 11.
  • FIG. 4 illustrates a training aid 10 where the membrane 11, once it has been filled with the liquid L and the gas G, takes on a substantially spherical shape.
  • the membrane 11 once it has been filled with the liquid L and the gas G, takes on a substantially spherical shape.
  • the remaining characteristics of the training aid are the same as those described for the implementation shown in figure 1 .
