Definitions

  • the present invention relates to the field of sport equipment used for making recreational activities in water, in particular in the sea, or the lake, etc.
  • the present invention relates to an engagement device for engaging a first and a second rowlock to a floating board, such as a SUP, or surf, board etc.
  • an activity for a long time widely widespread in the sea, but also in the lakes provides the use of floating boards similar to those used for windsurf, or surf, but that, differently from these activities, provide to use, as propulsion elements, a paddle that is operated by a user maintaining an erect position on the board.
  • SUP i.e. Stand Up Paddle
  • table In order to remain in the erect position on the floating board, commonly known as SUP, i.e. Stand Up Paddle, table, and, at the same time, to be able to paddle to produce the propulsion force that is necessary to move the same on the water surface, it is necessary that the user is able to keep his balance and has a great coordination. Therefore, for the reasons disclosed above, this kind of sport activity even though it can have a large circulation as a recreational activity, at the moment, is not widely widespread.
  • the devices that are described in the aforementioned documents provide to engage the rowlocks to the floating board by belts, tapes, or similar fixing elements, which need long times for assembling and disassembling.
  • the aforementioned devices are not able to guarantee the necessary stability conditions during the use by a user.
  • a device for engaging a first rowlock and a second rowlock to a floating board, in particular a SUP, or surf, board whose main characteristic is to comprise:
  • the main support body, the first and the second fixing portions are made in a single piece by moulding of plastic materials.
  • each engagement element of the aforementioned plurality can comprise:
  • a secondary support body configured to be positioned adjacent to the floating board at the opposite side to said main support body.
  • the aforementioned plurality of engagement elements is configured to "sandwich" the floating board between the main support body and the secondary support body.

More in particular, the aforementioned height (h) can be set between 60 cm and 170 cm, advantageously between 70 cm and 160 cm, preferably between 80 and 150 cm.
  • both the first and the second support bars are configured in such a way that their length can be adjusted.
  • the first and the second fixing portions can comprise a first part integral to the main support body, and a second part operatively connected to the first part, in such a way that it is possible to adjust the inclination of the second part and, therefore, of the support bar with respect to the floating board.
