Definitions

  • the present invention relates to an individual swimming driving device, designed to serve as a means to help a person move in water, especially to move in a submerged position.
  • the object of the present invention is to eliminate the problems described by means of an individual swimming drive device that is effective, safe, ergonomic and configurable, easily handled and silent.
  • the advance effect is produced by a fin with oscillating movement, which is located behind the swimmer, following it and as an extension of his body, simulating the movement movement of a fish.
  • the swimming driving device is composed of a drive unit, an oscillating fin and connection means that relate the motor unit to the oscillating fin.
  • the drive unit comprises a sealed casing in which a drive mechanism including a horizontal output shaft, perpendicular to the swimmer's direction of advancement, whose axis protrudes through opposite sides of the casing in respective sections to which they connect, is housed.
  • the connection means that relate the motor unit to the oscillating fin.
  • the housing of the power unit has an external platform, on which the feet of the swimmer are positioned, one on each side of the casing.
  • the connecting means of the motor unit to the oscillating fin are directed in the opposite direction to that occupied by the swimmer.
  • the drive mechanism housed in the housing is composed of a series of servomotors, electrically driven, which are arranged in two groups that mesh in diametrically opposite positions and form alternative and with opposite directions, on a central gear wheel whose axis constitutes the aforementioned horizontal output shaft of the drive unit, axis that is mounted on sealed end bearings, through which it protrudes from the housing on both sides.
  • the motor unit forms a sealed assembly and can be formed by a base and a lid joined together, for example, by means of screws or any other system, with the interposition of a sealing gasket.
  • the wall of the housing is traversed by the spindle of the gear wheel through sealed bearings.
  • the commented arrangement of the servomotors allows the compensation of tangential forces to be achieved on the central gear, so that the only resulting torque is the motor torque, which is an advantage in ensuring the tightness of the casing, preventing water from penetrating into it. through sealing joints.
  • the joints are subjected to tangential efforts, they suffer undesirable actions that, with the course of time, cause their deterioration, compromising the sealing of the casing.
  • the meshing of the servomotors with the central gear in diametrically opposite positions and alternatively in opposite directions, the risk of deterioration of the sealing joints of the casing is eliminated.
  • the external platform of the housing can be independent to be part of the drive unit.
  • This platform is preferably lightened to reduce the dead weight and can have material in the areas where the support of the foot (floor and heel) occurs, so that the reaction efforts produced are transmitted to the natural areas of the foot, reducing the fatigue.
  • These support areas can have a textured surface that improves grip and prevents slippage.
  • the fixation of the feet can be done by a band that fits around the instep and prevents the foot from rising off the platform. Where the support zone of the plant ends there may be a protuberance (retainer) that accompanies a part of the arch of the foot and prevents it from coming back.

  • These arms are attached to the unit to prevent elements from entering between them. They also move the connection area away from the fin, leaving a safety space, which avoids accidental clamping.
  • the drive unit Within the drive unit are the electronic components that govern the servomotors and communicate wirelessly (bluetooth, WIFI, zigbee, etc.) with the control device carried by the swimmer.
  • This device incorporates a touch screen, which avoids the use of push buttons, controls, cables and other elements that make it difficult to seal the assembly.
  • the control device sends commands to the unit: on, off, variation of the movement sequence of the fin, etc., and receives information of internal variables: battery status, consumption, temperatures, failures, etc.

  • the unit has an emergency stop.
  • This stop can be done by means of an element that incorporates a magnetic piece and has two positions where one of them coincides with an internal detector of the hall effect that acts stopping the movement.
  • This element is joined by a cord that goes up to the waist, where it is attached to a handle that conveniently allows stopping the device in case of emergency.
