[0002] In particular, 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.

Background of the invention

[0003] As well known, 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. 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.

[0004] In US9428253, US2018/015993, US10207783, EP3081477, US2014/187108, WO2015/022610 and US2012/108119 some examples are described of devices for engaging the rowlocks to a floating board.

Detailed description of some exemplary embodiments of the invention

[0020] As diagrammatically shown in figure 1, a device 1 for engaging a first and a second rowlock 11 and 12, to a floating board 100, in particular a SUP board, or a surf board, comprises a main support body 20, preferably a support plate 20. The main support body 20 provides a base surface 20c configured to be positioned adjacent to an upper surface 105 of the external surface 101 of the floating board 100. More precisely, the main support body 20 has a determined curvature in such a way that the base surface 20c of the same, in working conditions, is arranged to be positioned adjacent to the upper surface 105 of the external surface 101 of the floating board 100. According to the invention, the main support body 20 is provided with a first fixing portion 21 and a second fixing portion 22 configured to engage first end portions 31a and 32a of a first and a second support bar 31 and 32, respectively. In particular, the first and the second fixing portions 21 and 22 can be tubular-shaped, for example cylindrical-shaped. Advantageously, the first and the second fixing portion 21 and 22 are inclined at a predetermined angle α, for example set between 15° and 60°, with respect to a vertical direction.

[0021] According to an embodiment of the invention, not shown in the figure for simplicity reasons, the first and the second fixing portions 21 and 22 can be provided with stiffener portions, for example positioned within the same. For example, the stiffener portions can be cores, also this tubular-shaped, made of metallic material. In this way, the fixing portions 21 and 22 are stiffer and, therefore, can endure higher stresses during the use of the floating board 100.

[0022] In particular, the first and the second support bars 31 and 32, at respective second end portions 31b and 32b, opposite to the first end portions 31a and 32a, are provided with a respective rowlock 11 and 12, i.e. a support for a respective oar. Each rowlock 11, or 12, for example substantially "U-shaped" can be removably constrained to the aforementioned second end portion 31b, or 32b, of the respective support bar 31, or 32, for example by bolt, or threaded, coupling or by a join, or similar coupling mechanism. For example, as diagrammatically shown in figure 2A, the elongated portion of rowlock 11, or 12, can be arranged to removable engage into a hole 38 made at the second end portion 31b, or 32b, of the support bars 31 and 32.

[0023] The possibility is also provided of permanently engaging each rowlock 11, or 12, at the aforementioned second end portion 31b, 32b, of the respective support bar 31, 32, for example by welding, or gluing, or in such a way that they form a single piece, for example produced by a moulding process. The device 1 for engaging the rowlocks 11 and 12 to the floating board 100, furthermore, comprises a predetermined number of engagement elements 50 configured to removably engage the support plate 20 to the floating board 100.

[0024] According to the embodiment of the invention, the support plate 20, the first fixing portion 21 and the second fixing portion 22, can be independent components that are fixed one another by a coupling of fixed type, for example by welding, or gluing, or removably type, for example by bolts, or threaded coupling.

[0025] According to an alternative embodiment of the invention, the support plate 20, the first fixing portion 21 and the second fixing portion 22 are made in a single piece. More in detail, the support plate 20, the first fixing portion 21 and the second fixing portion 22 can be produced by a moulding process of plastic materials. For example, the plastic material can be a stiff plastic material selected from the group comprising: polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), acrylonitrile (ABS), polymethyl methacrylate (PMMA), polycarbonate (PC), or similar materials that are used in the moulding of plastic materials.

[0026] As diagrammatically shown, for example, in figure 3, each engagement element 50 can comprise a fixed portion 51 integral to the main support body 20, fixed to the same for example by screws, bolts, or glue. In particular, the fixed portion 51 is provided with tightening elements 53 configured to move from an opening position (unbroken line of figure 2B), to a tightening position (broken line of figure 2B), and vice versa. Each engagement element 50, furthermore, comprises a connection portion 52, preferably flexible, and having a first end 52a fixed to the floating board 100, in one, or more points, for example by gluing, or by a screw, or a rivet, or similar fixing elements, and a second end 52b. This is configured to engage the fixed portion 51 to be tightened by the aforementioned tightening elements 53 of the same when these are positioned in the tightening position, in such a way to block the flexible connection portion 52 in a determined position. In this way, the blocking of the support plate 20, and, therefore, of the rowlocks 11 and 12, to the floating board 100 is easily, but at the same time extremely effectively, provided. In an equally easy and quick way it is possible to disengage the rowlocks 11 and 12 from the floating board 100 causing the tightening elements 53 to move in the aforementioned opening position in which they free the second end 52b of the flexible connection portion 52.

[0027] In the alternative embodiment of the invention that is diagrammatically shown in the figures 6 and 7, the device 1 for engaging rowlocks 11, and 12, to the floating board 100, can, furthermore, comprise a secondary support body 25, in particular a counter-plate, configured to be positioned adjacent to the floating board 100 at the opposite side of the main support body 20, i.e. at a lower portion 104 of the external surface 101. Therefore, in this case, when the engagement elements 50 are arranged in the tightening position, they "sandwich" the floating board 100 between the support plate 20 and the secondary support body 25. More in detail, as shown in the transversal cross-section view of figure 7, each engagement element 50 provides a fixed portion 51 integral to the support plate 20, analogously to the embodiment shown in the figures from 1 to 5. Furthermore, each engagement element 50 comprises a flexible connection portion 52 having a first end 52a fixed to the secondary support body 25, in one, or more points, and a second end 52b configured to be removably engaged by the tightening elements 53 of the fixed portion 51.

[0028] Advantageously, both the main support body 20 and the secondary support body 25, if present, can be substantially "I-shaped", or substantially rectangular-shaped, or substantially square-shaped. It is also appropriate to specify that, as a skilled person in the art can easily understand, even though reference has been made to a first and a second end 52a and 52b, the engageable/disengageable portion with the tightening elements 53 and the fixed portion to the floating board 100, or to the secondary support body 25, are not necessarily positioned at the tail and the head of the flexible connection portion 52, but at intermediate positions.

[0029] As diagrammatically shown for example in figure 8, the first and the second support bars 31 and 32 are configured in such a way that the respective rowlocks 21 and 22 are positioned at a predetermined height h from the upper surface 105 of the external surface 101 of the floating board 100. In particular, the aforementioned height h is such that the user is arranged to use the oars, or the paddle, mounted on the rowlocks 21 and 22, in erect position. More in particular, the height h can be set between 60 cm and 170, for example between 65 cm and 160 cm, advantageously between 70 cm and 150 cm, for example between 75 cm and 120 cm.

[0030] According to a particular embodiment of the invention, diagrammatically shown in the figures 10 and 11, the support bars 31, and 32, can be configured in such a way that their length can be adjusted. In particular, each support bar 31 and 32 can be constituted of a first and at least a second elongated elements 33a and 33b, 34a and 34b, can move one with respect to the other between a first position (figure 10), in which the respective support bar 31, or 32, has a first length 11, and at least a second position (figure 11), in which the support bar 31, or 32 has a second length 12, with l1≠l2, for example 12>11. In this way, the device 1 for engaging the rowlocks 11 and 12 to the floating board 100 can be configured in such a way to allow the use of the floating board 100 to users 200 of different heights, or anyway to allow the same user 200 to assume different postures during the exercise.

[0031] In particular, the first and second bars 31 and 32 can have a telescopic structure. In particular, blocking elements can be provided arranged to block the first and second elongated elements 33a, 33b and 34, 34b in a determined relative position corresponding to the aforementioned length of the respective support bar 31 and 32.

[0032] According to an alternative embodiment of the invention that is diagrammatically shown in the figures from 12 to 14, the first and the second fixing portions 21, and 22, comprise, respectively, a first part 21a, 22a, integral to the main support body 20, and a second part 21b, 22b, rotatably connected to the first part 21a, 22a, for example by a ball joint 23, or an articulated joint, or another device for adjusting the relative inclination. In this way, it is possible to adjust the inclination of the second part 21b, 22b with respect to the first part 21a, 22a and, therefore, of the support bar 31, 32, with respect to the floating board 100. For example, as diagrammatically shown in the figures 13 and 14, it is possible to move from a first inclination α1 with respect to the vertical direction (figure 13) to a second inclination α2 with respect to the vertical direction (figure 14). In particular, the device for adjusting the inclination is arranged to set a determined angle α formed by each fixing portion 21 and 22 with respect to the vertical direction. Advantageously, the inclination of the fixing portions 21 and 22 with respect to the vertical direction can be adjusted by the aforementioned device for adjusting the inclination, in such a way that the aforementioned angle amplitude α is set between 15° and 60°.

[0033] As diagrammatically shown in the alternative embodiment of figures 15 and 16, the engagement device 1 can, furthermore, comprise a first and a second side engagement body 40a and 40b configured to engage respective opposite lateral edges 100a and 100b of the floating board 100. Preferably, the first and the second side engagement bodies 40a and 40b are configured to extend between the upper surface 105 and the lower surface 104 of the floating board 100. In particular, the first and the second side engagement bodies 40a and 40b can be made of plastic material. More in particular, the first and the second side engagement bodies 40a and 40b can be produced by moulding of plastic material.

[0034] Advantageously the plastic material of the first and second side engagement bodies 40a and 40b can be a stiff plastic material, in particular selected from the group comprising: polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), acrylonitrile (ABS), polymethyl methacrylate (PMMA), polycarbonate (PC), or similar materials used for moulding plastic materials. For example, the first and second side engagement bodies 40a and 40b can be produced using the same mould.

[0035] In particular, the first and second side engagement bodies 40a and 40b can be substantially "C-shaped". More in particular, the first and second side engagement bodies 40a and 40b are arranged to engage the floating board 100 at opposite sides with respect to the support plate 20.

[0036] Advantageously, the plurality of engagement elements 50 comprises a first group of engagement elements 60 arranged to removably engage the first and second side engagement bodies 40a and 40b to the main support body 20 at respective engagement surfaces 20a and 20b.

[0037] In particular, the first group of engagement elements 60 can comprise a predetermined number of engagement holes 61 made at one of the engagement surfaces 41a, or 20a and 41b, or 20b, of the first and the second side engagement bodies 40a and 40b, or of the main support body 20, and a corresponding number of elongated engagement elements, for example fixing pins, or screws, bolts, or similar fixing elements, arranged to removable engage into the aforementioned engagement holes 61, advantageously blind engagement holes 61, for example by a shape coupling, or a force coupling, or a threaded coupling. In particular, in the case of screws, bolts, and similar fixing elements which need a tool to screw the same into the corresponding engagement holes, the first and second side engagement bodies 40a and 40b provide through holes 63, each of which arranged to house, in use, the head of a respective engagement element 62, for example a stud bolt, or an engagement pin.

[0038] Advantageously, at the faces 42a and 42b of the first and second side engagement bodies 40a and 40b arranged, in use, to be positioned adjacent to the edges 100a and 100b of the floating board 100, spacer elements, in particular made of soft material, can be provided. In this way, it is possible to avoid that during the use of device 1 for engaging the rowlocks 11 and 12 to the floating board 100, the lateral edges 100a and 100b of the same can be scratched.

[0039] In particular, the faces 42a and 42b of the first and the second side engagement bodies 40a and 40b are arranged, in use, to be positioned adjacent to the edges 100a and 100b of the floating board 100, are positioned, in use, below the aforementioned engagement surfaces 41a and 41b, and, advantageously, at a position more distant from the floating board 100 with respect to the same.

[0040] Furthermore, the plurality of engagement elements can comprise a second group of engagement elements, not shown in the figure for reason of simplicity. In particular, the second group of engagement elements can comprise a predetermined number of engagement elements arranged to tighten the first and second side engagement bodies 40a and 40b to the board 100 at respective edges 100a and 100b.

[0041] In particular, according to an embodiment of the invention, the first fixing portion 21 and the second fixing portion 22 can be provided with respective housing holes 24 arranged to house the first end portions 31a and 32a of the support bars 31 and 32 (figure 1), or a protruding portion 39 of the same (figure 15). More in detail, the first end portions 31a and 32a or their aforementioned protruding portions 39 can have a polygonal cross section, in particular a hexagonal cross section, in order to prevent the same from rotating with respect to the first and second fixing portions 21 and 22 during the use of the floating board 100 by the user.

[0042] Still with reference to the example of figure 15 and 16, each of the second end portions 31b and 32b of the support bars 31 and 32 can comprise a respective fixed portion 37, i.e. integral, respectively, to the first and to the second bar 31 and 32, and a movable portion 38 configured to move with respect to the fixed portion 37. In particular, the movable portion 38 can be rotatably engaged to the fixed portion 37 about a rotation axis 138, in particular a substantially vertical rotation axis. In this way, it is possible to adjust the position of the fixed portion 37 at which the rowlock 11, or 12, is rotatably engaged to the first, or the second support bar 31, or 32, in such a way that the user can adjust the position of the same, and, therefore, of the respective oar, accordingly to an ideal posture.

[0043] Furthermore, at each second end portion 31b and 32b of the support bars 31 and 32 a knob 35 can be, advantageously, provided at which a user can act to cause the aforementioned rotation of the movable portion 38 with respect to the fixed portion 37. In particular, the aforementioned knob 35 can be operatively connected to a self-locking device configured to block, or unblock, the rotation of the movable portion with respect to the fixed portion, for example comprising gear transmission components as for example toothed wheels, not shown in the figures for reason of simplicity.
