Definitions
- the invention relates to swimming systems and can be used in educational, recreational or rehabilitation swimming systems, including virtual reality simulation systems.
- the inventive system is intended mainly for snorkeling, that is, swimming under the surface of the water with a mask and breathing tube, but can also be used for other types of movement of the user (swimmer) in the aquatic environment.
- the resulting vertical force component does not introduce significant problems in terms of simulation calculations.
- this component can have a negative effect directly on the swimmer.
- a swimmer When a swimmer is attached to a brace located below, it can be pulled quite strongly under water, which will lead to a change in the angle of the body (deviation of the user's body from a horizontal position, the swimmer's belt is tightened to a depth), and at the maximum depth - to breathing problems through the snorkel (the swimmer's head is also tightened to the depth).
- Top-secured stretching is less of a problem, as stretching while swimming pulls the user up. In this case, the body first assumes a more horizontal position under water, which, as a rule, does not interfere with swimming, and when the body is pulled above the water surface, the Archimedes force decreases, which leads to an effective counteraction to further stretching.
- the implementation of a snorkeling system with the swimmer attached to the top brace is preferable and provides sufficient comfort for the user's small swimming efforts.
- pulling the swimmer to the surface of the water and stretching the brace leads to a decrease in the effect of presence in virtual reality, expressed in the heterogeneity of physical sensations when the user overcomes homogeneous areas in virtual space.
- the tension of the stretch is minimal and the user receives sensations close to those of free swimming.
- the problems associated with keeping a swimmer within a certain swimming area are solved by known systems designed for training swimmers and learning to swim. In particular, they are aimed at solving the problems of keeping a swimmer at a certain depth, preventing him from involuntarily going underwater with insufficient swimming skills, as well as reducing the necessary swimming area (length of the pool), mainly ensuring the movement of the swimmer on the spot.
- These are devices that create a flow of water that impedes movement, or which are a system of braces that hold the swimmer in place, which ensure its buoyancy at a certain depth and in a certain direction. They usually include a support on which is mounted an element designed to hold the swimmer directly or through intermediaries.
- one end of the retaining element is connected to the swimmer, and the other end is attached to the supports at the edge of the pool (CN206616898U, US7185598B1, US2010009813A1, US4527795A, US7442151B1, US4109905A, US4530497A, etc.) or held ashore by a container with a significant weight (US582496)2 mobile restraint (US2020122812A1, US5244393A, WO2017034939A1).
- a swimming training device comprising an elastic element mounted on a bracket (for example, in the form of a spring), enclosed in a housing to which an elastic cable connected to the user is attached.
- the swimming device according to US2010009813A1 contains a flexible retaining cable (elastic cord, elastic strap) connected to the swimmer and capable of elastic stretching, which on the other hand is connected to the fastening rod.
- the device according to US7273444B2 includes a suspended retaining element made in the form of an elastic tube, inside which is placed a retaining cable, and the cable may be less elastic than the tube, and is designed to limit the elongation of the tube; moreover, the holding element is connected to the bracket so that it can move along the bracket.
- the element directly connected to the user is a stretch, that is, a tensile element with significant elasticity.
- the use of stretching can be associated with a number of problems.
- the stretcher is not able to maintain orientation in space and only limits the movement of its user-associated end.
- the stretch does not create a restoring force, but only deviates, and the restoring force arises as a result of gravity or buoyancy.
- a body that is suspended on a stretch in water, which has neutral buoyancy, will not be subject to the action of a restoring force during displacement until its buoyancy decreases with some deflection of the body and its rise from the water.
- Neutral buoyancy will disappear, and the body will begin to sink back into the water. In some cone-shaped area under the rope, no forces act on the body, and it is in free float. When deflected, depending on the radius of the rope, an action of forces arises, which can be quite sharp.
- brace fastening directly to the side of the pool which limits movement only in the direction of movement from the side of the pool (US5816982A, US4109905A, US4527795A);
- an elastic rod for example, made of fiberglass, to which an extension (cable) is connected, can be used.
- the device allows you to create an upward force A, close to the force of gliding, holding the swimmer on the surface of the water. At the same time, the holding force B, directed back, keeps the swimmer in a certain zone.
- a similar approach is used in the simulator according to US7563206B1, where, through the use of an elastic support element, a force is also created to lift the swimmer to the surface.
- Known swimmer retention systems provide elastic fixation and the ability to move in one direction. When the swimmer turns and moves back to the shore, such systems are not able to perform the function of holding and limiting the swimmer in a given space. That is, known systems do not solve the problem of restricting the movement of a swimmer in all directions in a certain selected area.
- the claimed invention allows you to create a force that returns the user (swimmer) to a certain swimming area when he moves in any direction on the surface of the water - from the side of the pool and back to it.
- the system has less effect on the swimmer along the vertical axis and this effect does not depend on the swimmer's deviation from the equilibrium position. This increases the effect of the user's presence when used in virtual reality simulation systems, and also reduces the requirements for the supporting part of the proposed system.
- the inventive system for limiting the movement of a user (swimmer) in the aquatic environment contains a bending-elastic element, one end of which (retaining end) is designed to be connected to the swimmer, and the second end (retained end) is designed to be fixed using a support system.
- the restoring force in this case is generated by the element holding the swimmer, which defines a swimming area around itself.
- the system is organized in such a way that allows such movement of the elastic element as a whole without its deformation, in which the height of the holding end changes within the limits of the natural change in the depth of the user when swimming along the water surface.
- the entire elastic element moves without deformation, and its position changes so that the position of its holding end changes vertically, following the movements of the swimmer.
- the swimmer thus has a vertical degree of freedom and is not affected in this direction by the restoring strain force of the elastic element.
- the system provides a uniform feel to the swimmer as it does not pull the swimmer underwater or forcefully out of the water in response to approaching the edge of the swim zone.
- the system does not actually restrict the swimmer's vertical movement while swimming along the water surface.
- the elastic element must be installed so that a significant displacement of the swimmer in any horizontal direction causes the elastic element to bend. That is, the response of the elastic element to the user's movement along the water surface is precisely its bending, and not, for example, stretching, as in known systems.
- the system continues to perform its function, that is, to keep the swimmer in a certain swimming area, creating a return force in relation to the swimmer.
- the entire holding element moves vertically, or its orientation in space changes slightly.
- the holding element which provides uniform restoring forces in all horizontal directions at the same depth of the user's position, moving upwards in parallel or almost parallel with a change in depth, will also maintain uniformity of restoring forces for all horizontal directions.
- the horizontal coordinates of its holding end do not change, which means that the depth changes without shifting the user, and the center of the simulation zone, where the system returns the user, is in the same horizontal coordinates regardless of the depth.
- the freedom of the user in the vertical direction can be achieved, for example, by placing the system of supports on the supporting surface with the possibility of their rotational movement relatively close to the horizontal axis, remote from the center of the navigation zone.
- the freedom of rotation of the support about the specified axis is transferred to the elastic element, making it possible to move around the circumference in a vertical plane, which changes the height of the holding end of the support element.
- the retained end of the elastic element is rigidly connected to the ends of two inclined supports, the opposite ends of which are fixed at points spaced apart from each other, remote from the center of the navigation zone.
- the rotation of the support system and the elastic element is provided relative to a straight line passing through the support fixing points.
- the resilient element is slidably connected to a system of at least two supports resting on different points remote from the center of the navigation area.
- the elastic element can be connected (associated) with the swimmer through a module attached to his body or held by him in his hands.
- the elastic element can be made bent in the direction opposite to the swimmer's head, in a place corresponding to the level of the swimmer's head, and have freedom of rotation about an axis close to vertical.
- the elastic element can be connected to the swimmer through an intermediary element, which ensures the rotational mobility of the swimmer around the elastic element.
- the system is used for virtual reality simulation systems to reduce the impact on the user of unwanted forces and increase the effect of presence.
- the horizontal force acting on the swimmer changes more smoothly when he changes the direction of his movement and moves near the equilibrium point.
- the homogeneity of sensations increases when deviating from the equilibrium position, due to a more uniform vertical load on the user, that is, a load that does not depend or weakly depends on the horizontal displacement of the swimmer.
- Figures 1-4 show the first version of the system with hinged support:
- FIG. 1 implementation of a system with one support
- FIG. 2 the behavior of the system in dynamics when the swimmer rises (hereinafter, arrows of increased thickness indicate the direction of deflection of the system elements in response to the user's actions);
- FIG. 5 the preferred implementation of the system according to the first variant with two spaced supports
- FIG. 6-9 show the second version of the system:
- FIG. 8 - with rigid fastening of two supports opposite each other with the possibility of translational movement of the elastic element during the vertical movement of the swimmer;
- FIG. 11 - elastic element in the form of a C-shaped bracket
- FIG. 12 an elastic element of a trapezoidal shape
- FIG. 14 the action of forces on the user when he is fixed with a suspension (stretch), for comparison.
- the movement limitation system allows you to keep the user (in particular, the swimmer) in a certain zone of the water space (swimming zone, simulation zone) with an elastic bending element 1.
- swimming means any user activity in the aquatic environment with the application of forces that can cause the user to move.
- the elastic element 1 is connected with the swimmer with one of its ends (retaining end 2), and the second end (retained end 3) is fixed on the support system (see Fig. ), for example, above or below the water surface.
- a support system for the elastic element 1 a system can be used in the form of a single support element 4 or several support elements 4 interconnected and fixed on the support surface 5, as well as the support surface itself - the side of the pool, its bottom or ceiling.
- the fixation of the retained end 3 should be such that a significant displacement of the swimmer in any horizontal direction would lead to bending of the elastic element 1. That is, for any depth of the retaining end 2 there is such an area in the horizontal plane at the depth of its placement that the extension of the retaining end 2 beyond the limits of this area leads to bending of the elastic element 1.
- the reaction of the elastic element 1 to the horizontal displacement of the swimmer is precisely bending, and not stretching.
- any restraint system it is possible to define a zone that the user must not leave, and, as a rule, some displacement of the user within this zone is allowed.
- the size and shape of the swimming area is determined by the size and shape of the pool, and outside of this area there may be physical obstacles, such as the edge of the pool, from which the user must be protected from touching.
- the fixation system must respond by returning force to prevent further displacement.
- the elastic element 1 can be connected to the swimmer in a way that allows it (the swimmer) to rotate about the vertical axis, independently or together with the elastic element 1.
- the connection to the swimmer can be articulated or elastic, using a short flexible mediator element (for example, from a rope or rubber) or other known compound that provides rotational mobility of the swimmer at the attachment point of the elastic element 1 within the limits sufficient for its free swimming.
- the system is organized in such a way that allows the movement of the elastic element 1 as a whole without its deformation (for example, stretching).
- the height of the holding end 2 relative to the selected horizontal surface changes, that is, it moves vertically.
- the displacement is made at least within the limits of the natural change in the depth at which the swimmer is located when he swims along the surface of the water.
- the holding end 2 should preferably not move horizontally or only slightly when the depth changes. Otherwise, when changing the depth, the user will feel horizontal pressure from the side of the holding end 2, which is not associated with the user's swimming activity, and the center of the swimming zone at different depths will have different horizontal coordinates, which is meaningless for pools with vertical walls.
- the reference points of the system are not required to support the weight of the swimmer, and in the version with supports that can rotate about the horizontal axis - and most of the entire weight of the system, since it "relies" on the water, the swimmer, buoyancy element. This allows you to significantly reduce the requirements for securing the system on the shore. It is sufficient to limit its movement along the coast, the movement of the ends under the action of small forces. Since the system does not respond to the swimmer's weight, it does not have a destructive effect on it; the effect of the swimmer's weight is not transferred to the system, which further reduces the requirements for the system's supports.
- the inventive system has a more uniform effect on the swimmer; does not keep it from sinking, does not “pull” it out of the water and does not “pull” it under water, that is, it does not have an extra effect that does not have visual or other reinforcement in virtual reality by reducing the negative impact of the vertical component of the force.
- the vertical component of the force acting on the swimmer from the side of the system increases as the swimmer deviates from the center of the swimming area. This negative impact is associated with the heterogeneity of the vertical component.
- the system quickly absorbs the vertical component of the forces (especially sharp forces) of the user's movements, such a vertical effect creates a feeling of an imposed restriction.
- the claimed system achieves minimization of the vertical component of the force from the holding system, for example, by creating vertical freedom of movement of the system's attachment point on the user's body, at least within the limits of changing the depth of its location in the process of free floating of the user along the water surface.
- the limits of the vertical movement of this point during natural navigation we call the limits of the natural change in the depth of the user's location.
- the elastic element 1 is the main element that ensures a smooth return of the swimmer to the center of the swimming area. It can be a rod of the required length.
- the elastic element 1 is made of a material that allows it to return to its original shape after bending deformation under conditions of horizontal mobility with the force expected from the user. Due to its elasticity, the element 1 ensures the return of the system to the central equilibrium position when the swimming efforts are removed.
- the elastic element 1 can be made, for example, of fiberglass, carbon fiber, metal.
- the elasticity of the element 1 can be selected based on the size of the pool (the area of the desired swimming area) and the nature of the efforts of the swimmer. For smaller sizes and/or a more sporty style of swimming, this item can be stiffer. For larger pools and/or relaxed swimming, the stiffness can be reduced instead. This adjustment can also be made by increasing or decreasing the active length of the elastic element 1 by shifting the connection point of the elastic element 1 and supporting elements 4.
- the vertical mobility of the holding end 2 of the elastic element 1 can be achieved by allowing the translational movement of the elastic element 1 along a nearly vertical axis in response to the movement of the swimmer.
- the support element 4 can be installed with the possibility of rotational movement relatively close to the horizontal axis, remote from the center of the navigation area.
- the load is removed from the supporting part of the system (system attachment points on the supporting surface), they do not need to support their own weight, which is especially important when using long, heavy and massive supports.
- Anchoring points can be located near the perimeter of the pool, that is, in the vicinity of the water boundary, the water separation zone and the shore / sides of the pool, or in the case of use in an open water body, on another movable or immovable object (pier, boat, etc.) .
- the height of their location can be different, both above the water level and below the floor level of the pool; that is, an indication of the location "near” can refer to both vertical and horizontal displacement relative to the surface of the water.
- Indications of an axis close to the vertical or horizontal imply the possibility of placing the element both on the corresponding axis - horizontal or vertical, and on an inclined axis close to it. At the same time, the location as close as possible to or on such an axis is preferred, and the deviation is acceptable as long as sufficient uniformity of the generated force is ensured.
- a rigid or rigidly elastic support element 4 can act as a support.
- at least one support element 4 is connected with the support surface 5 at its first end, and with the elastic retaining element 1 with its second end.
- the connection can be rigid or allow rotation and/or shift of the elastic element 1 along an axis close to vertical.
- the support element 4 must have sufficient strength and rigidity to prevent significant horizontal displacement of the connection point of the support element 4 with the elastic element 1 under the action of the swimmer's swimming efforts, and the displacement is significant compared to the horizontal displacement of the swimmer itself.
- the support element 4 may have some elasticity.
- the rigidity of a single support element 4, for example, attached to the side, bottom or ceiling of the pool must be significantly higher than the rigidity of the elastic element 1.
- two support elements 4 for example, forming a triangular shape, relying on one side of the pool, their rigidity can be reduced due to the greater rigidity of the structure.
- Still less rigid support elements 4 can be used if three or more support elements 4 form a pyramidal or domed shape, for example, resting on different sides of the pool.
- the supporting elements 4 can be made, for example, of tubes of aluminum alloy, fiberglass or carbon fiber. For ease of storage and transportation, the supporting elements 4 can also be made of separate shorter knees.
- the system has such a geometry that its elements do not interfere with free swimming in any direction.
- the height of the supporting elements 4 above the surface must be sufficient for the free passage of the snorkel tube under them when the swimmer turns.
- the support elements 4 should be located in a zone where they are not touched by the swimmer's legs.
- the system can be implemented in various ways.
- connection of the support element 4 with the support surface 5 is chosen, which makes it possible to rotate it about a horizontal axis passing through the point / points of connection with the support surface 5.
- the support element 4 can be fixed with a swivel joint. Since the system is not designed to keep the swimmer from moving in the vertical direction, no support is required in that direction.
- the opposite end of the hinged support element 4 is movable in the vertical plane and, together with the elastic element 1 and the swimmer, can move freely in the vertical plane along a large radius circle determined by the length of the support element 4, thus allowing the swimmer to freely change the depth of the swimmer with any deviation from the center. zones.
- the weight of the support can be offset by creating additional buoyancy, for example, by placing buoyancy elements on the swimmer's belt or at the end of the support element 4.
- the support element 4 (bracket) is fixed by means of an axial hinge on the shore (on the side of the pool).
- the shape of the bracket allows the swimmer to swim freely under it without touching it with the snorkel, and the elasticity of the retaining element 1 allows the swimmer to return to its original central position in the pool when deviating from it.
- the system allows the swimmer to move in the vertical direction ( ) and remains operational when the swimmer turns ( , ).
- the preferred implementation of the system according to the first embodiment is shown in .
- the system contains two inclined support elements 4 installed on the support surface 5 at a distance from each other and rigidly connected to the elastic element 1 to form a triangular pyramid.
- the reference points of the elements 4 are removed from the center of the navigation zone, and the rotation of the elements 1 and 4 occurs relative to the straight line passing through them.
- the rigid triangle formed by the supporting elements 4 can rotate relative to the axis of fastening on the shore.
- the mutual arrangement of the support elements 4 improves the stability of the structure in the main working horizontal direction. This results in a light, quick-detachable and stable design.
- the support surfaces 5 can be any two attachment points, for example, the handrails of the pool or its side. Fixation to the supporting surface 5 can be carried out using suction cups. This design can be installed using only one side of the pool, does not require other walls and elevations, therefore it is suitable for use in large and outdoor pools.
- the vertical mobility of the swimmer is realized due to the possibility of translational movement of the elastic element 1 in response to the movement of the swimmer relative to the fixed support element 4 (or the system of support elements 4) at their junction in a direction close to vertical.
- the immobility of the supports in the place of fixing the elastic element 1 in this case can be achieved in various ways. For example, by rigidly fixing a rigid support element-bracket 4 with a sufficient support base on the support surface 5 (see Fig. ), which can be the side or the bottom of the pool ( ), wall or ceiling of the room.
- Immobility can also be achieved by creating a rigid structure of several supporting elements 4, based on spaced points in space (for example, on opposite sides of the pool), the ends of which are connected above the center of the swimming area.
- Such an implementation is effective when it is possible to create a fixed or slow-moving point directly above or below the center of the movement zone using the support elements.
- This option can be most effectively implemented using support elements 4 installed on opposite sides (shores) (see Fig. , ).
- the supporting elements 4 are interconnected above the water surface to form a "dome", at the top of which an elastic element 1 is installed with the ability to move forward.
- This design reduces the requirements for the rigidity of fastening of the supporting elements 4 on the supporting surface 5 and limiting their mobility, since their rotation is blocked by mutual fixation.
- it is optimal to use a system of three or more support elements 4 ( ), which are interconnected and rest on different points of the pool perimeter, and the connection with the elastic element 1 is made sliding with the possibility of its translational movement in response to the movements of the swimmer.
- the support element 4 can be connected to the swimmer directly or using an intermediary element.
- the elastic element 1 can be connected to the swimmer through the module 6, which is held by the swimmer in his hands or fixed on his body, for example, placed on a vest.
- Module 6 can be equipped with handles for holding it with two hands in front of you (see fig. , ), which allows you to abandon the use of a swimmer's belt, harness. In this way, the process of preparing a swimmer for swimming using the system can be simplified and accelerated.
- the module can perform the functions of a hand-held game controller, simulating the virtual space of the action of various weapons and tools held with two hands (weapon, camera), which expands the range of possible game scenarios without complicating the system and adding new monitored devices.
- it is possible to provide it with greater freedom of vertical displacement (in comparison with other versions of the proposed system) for the possibility of free movement of the module in front of the user.
- the shape and method of connecting the support element 4, the elastic element 1 and the module 6 can be selected to ensure the best mobility of the swimmer with the least risk of collision with the elements of the system.
- the bent shape of the elastic element 1 allows the swimmer to avoid a collision of the head and the snorkel while holding the module 6 in the hands.
- the elastic element must have freedom of rotation about an axis close to vertical, so that the position of its bend corresponds to the direction of the user's navigation.
- the elastic element 1 can be made in the form of a C-shaped bracket ( ) or have a trapezoidal shape ( ).
- FIG. 13 shows the forces acting on a swimmer held in the central zone by an elastic element in the form of an elastic bending rod at the moment of the swimmer's maximum deviation from the equilibrium position when applying the maximum swimming force in the horizontal direction.
- Fig. 14 shows the forces acting on the swimmer at his maximum displacement from the equilibrium position while holding him with the help of a suspension (stretching).
- the swimmer also applies force in the horizontal direction.
- Strength stretching tension directed to the point of attachment of the brace fixed at a height deviated from the vertical by an angle .
- buoyancy begins to decrease only when the user deviates, partially lifting him out of the water (then, with the same weight, the Archimedes force begins to decrease).
- the brace begins to lift the user out of the water, the user is not subjected to any horizontal forces from the brace, resulting in the above-described jerk effect when the brace is loaded.
- an elastic retaining element makes it possible to reduce the required area of the reservoir, in particular, the simulation zone, as well as to achieve a more uniform distribution of forces.
