Definitions

  • the present invention relates an apparatus that enables a person to stand up and to move easily across the surface of water using a simple alternate foot motion.
  • the device according to the invention consists of a pair of floats or of a board shaped float that are as small as possible in size, but are sufficient to keep a person afloat, and are roughly boat-hull shaped.
  • the top surface of each float or of the board has a 'shoe-like' fitting of a known type, such as of the type fitted to water skis, for housing the feet of the person using the device.
  • the two devices (1 and 1') according to the invention consist of two elements made of a lightweight material, such as expanded resin or similar, each shaped like a boat hull and of a length, width, and cross-section that is large enough to support, in the water, half the weight of a person.
  • a lightweight material such as expanded resin or similar
  • each of these floats there are flipper shaped fins (2 and 2', and 3 and 3') the front edge (4 and 4', and 5 and 5') of each of which is respectively hinged so that it can be in one of two positions: open and at a certain angle to the side of the float, or closed and flat against the side of the float.
  • each of these floats which essentially consists of a sort of shoe (5 and 5') into which the foot of the person using the device fits, and known means (6 and 6') for closing the 'shoe' and fitting the device stably to the user's foot.
  • the device operates as follows: When one of the user's feet wearing the device is moved forward, the fins close so as to offer the least resistance to forward motion, which the shape of the float is also designed to offer. If the user pushes one of his feet backwards, the fins open and push against the water causing the other foot to move forwards, and in this fashion it is possible to walk on water by alternately moving one or the other foot.
  • the device according to the invention consists of a floating element (11) made of a lightweight material (expanded resin or similar), and shaped like a small surf-board, whose length, width, and cross-section are such that, on the water, they are capable of supporting the weight of a person, with reference to a particular type and thus weight of person.
  • the board may present any form of special curves, keel, or ribbing, etc., aimed at enabling it to be easier to propel and more stable in the water.
  • tubular supports (12 and 12') that are of a height in proportion to the average height of the type of person the floating board is intended to be used by, and which may, if necessary, be adjustable in height.
  • the device is fitted with two skates (13 and 13') that are in turn each fitted with a pair of concave rimmed front wheels (14 and 14') and rear wheels (15 and 15'). These wheels run on parallel tracks consisting of a pair of tubular elements (16 and 17, and 16' and 17') set lengthwise 20 across the board.
  • the upper surfaces of the skates (13 and 13') are covered with a rubber type material, so that the feet of the person using the device can get the required grip.
  • the device operates as follows: The person using the board places his feet on the skates (13 and 13'), and when he moves one of his feet forward, the respective flap closes by pivoting around until it is positioned parallel to the board (11) so as to offer the least resistance to the forward motion of the device. If the person using the board pushes one of his feet backwards, the respective flap opens thus pushing against the water and causing the device to move forwards.
  • the device may be fitted with a system of multiple flaps, instead of single flaps (19 and 19'), consisting of a frame (21 and 21') rigidly connected to its respective skate by an element (22 and 22').
  • the upper edges of two or more flaps (23, 23', and 23'', etc. ) are hinged to these frames (21 and 21').
  • the skates (13 and 13') instead of simply being fitted with a non-slip surface, can be fitted with means aimed at preventing feet slipping off the skates, means which could obviously consist of straps or other systems aimed at connecting the skates to the feet of the person using them.
  • the floats having only one fin attached to their external sides, instead fins attached to both sides, or the fin/s may be attached to the float in different positions to that illustrated, or the shape of the devices themselves may be different as a consequence of their design and characteristics being aimed at getting the best performance from devices of the smallest dimensions.
