Definitions

  • the invention is a small foldable single-seated human-powered boat, according to the preamble of claim 1, propelled by pedals and at least a single front paddlewheel, designed mainly for leisure purposes in calm waters, as a boat known from CA 2 522 858 . It is made mostly of plastic materials for avoiding or minimizing maintenance and corrosion. Its main feature is that is foldable around an axis transverse to the boat, becoming a kind of trolley or wheeled cart with a handle for dragging it by land, shortening its length to next to the half when folded. By this way it is easily transportable by the user on land, or even on irregular terrain or stairs when folded. The storage and stacking is too easy, so it can be placed into a cabinet, trunk or any kind of small space.
  • the foldable pedal boat is preferably a catamaran, with their two folding halves in form of floating bodies having each two lateral main floats with a central platform or bridge connecting both of them in form of a whole main folding piece or body that folds over the other one.
  • This platform or bridge gives too a seat for the passenger.
  • the main advantage of the foldable pedal boat is the ability to be folded and unfolded in only few seconds, being firmly fixed in both open and closed positions and ready for navigation or for storage or transport by land. It uses one or two symmetrical U-shaped tube bars whose arms can slide longitudinally into holes molded, shaped or practiced in both the two main halves of the boat, and they are fixed with pins for fixing them in both folded and unfolded positions. In the unfolded position, both U-shaped bars are movable between two stoppers for adjusting the backrest and the pedals to the passenger in several positions, but with no possibilities that they can be accidentally loosen or released and the boat folded in navigation. These symmetrical U-shaped tube bars serve too as a handle and as a locking device for maintaining folded the boat into a trolley form, and for chaining, stacking or hanging it if necessary.
  • the small size and capabilities for saving time and for easy transport have the price to limit their uses into relatively calm waters such as lakes, pools, or calm beaches or rivers. It can be interesting for individuals who want to save leisure time or to have a very small boat portable by land, as for recreattonal and hotel companies or water parks that want to have a number of these easily storable boats for their guests or customers in especially equipped recreational areas.
  • the documents US3175234A1 , SU1754568A1 , US5353733A1 and US3594834A1 describe foldable single-hull boats or foldable dugout canoes split in two foldable halves, with the peculiarity that they are foldable along a middle axis transverse to it, to which can be attached optionally wheels or a frame with wheels for transforming them into a kind of trailer for being transported towed by a motor vehicle.
  • the document ES2128887A1 describes a motorized catamaran for sailing that is foldable along an axis transverse to the boat with a frame convertible in a trailer for transportation by a vehicle.
  • the document DE3302276A1 describes a motorized single-hull vessel that can be folded by a central transverse axis, and whose prow section has retractable wheels for converting it into a trailer and being towed by a vehicle.
  • the document US3061845A1 describes a collapsible amphibian catamaran, in which the floats are split in two halve and can be folded one over the other. Its main particularity is that the floats are mounted on a trame with pivoting wheels that, being lowered by levers, convert the catamaran on a trailer towable by a car. All of these are single-hull foldable boats, when this invention is a catamaran-type foldable boat.
  • the document US5870966 "Folding Pontoon Boat” describes a collapsible foldable boat with two floats, each one divided into two halves.
  • the floats have two side wheels each one, leaving them up and above the water level when the boat is open, and down when it is closed, transforming it into a kind of four-wheeled cart.
  • the two side floats are folded rotating symmetrically 90° around two symmetrical longitudinal axes in relation of the vertical longitudinal symmetry plane of the boat, fitting under a horizontal frame that is a primary platform which has a seat for the passenger.
  • the floats are divided too transversely in two parts, allowing a second folding of the structure along an axis perpendicular to the first ones, housing the seat among some holes especially practiced in both prow and stern of the floats, so that the whole boat is compacted into a wheeled box whose dimensions are half the length and half the width of the boat when is open.
  • the main previous inventions that are most similar to the one presented here are:
  • the document US2745118 "Catamaran” describes a collapsible catamaran. It has two floats attached to a horizontal platform, that is foldable according to a transverse axis, made of wood or any solid material, which can fold like a book, below of which the floats are attached thereto.
  • the floats are split into three sliced sections (forward, middle and rear), so that when the middle section of such floats is attached simultaneously to both folding sides of the main folding platform, the folding is not possible due to rigidity.
  • it is not a foldable catamaran boat, but a catamaran whose main platform is foldable and to which two detachable floats must be attached later.
  • the boat itself is then detachable but not foldable as the presented invention.
  • a removable support with a leaf spring suspension system and wheels which can change its position on the foldable boat, allows the conversion to a trailer for being towed by a motor vehicle.
  • a longitudinal platform or box anchored simultaneously to each of the two folding parts maintains rigid the structure in the unfolded position.
  • the main diference with the invention of this document is the securing elements of the unfolded boat.
  • the presented invention obtains rigidity by two sliding U-shaped tube bars, front and rear, that can be introduced longitudinally and simultaneously into parallel holes practiced inside the other folding half platform of the boat.
  • the wheels in the previous invention are detachable and not coincident with the folding axis, while the presented invention has a common axis for folding movement, the steering levers and the transport wheels. Then, the invention presented in this document has no detachable elements because the compaction movements are by folding and sliding, with no necessity of removing pieces from the structure as this previous invention.
  • the split floats can pivot separately 180° inwards around longitudinal hinges placed at the central frame so that the boat is finally packed in a box whose dimensions are about half of the length and half the width of the craft unfolded.
  • This invention has two foding steps instead of a single one, and resembles in this aspect the document US5870966 .
  • the invention presented in this document too differs mainly from this one by the sliding elements that give rigidity to the structure when unfolded, as it is previously cited.
  • the folding of the two frame parts gives the folding of the entire structure and the floats being attached to them.
  • the strenghtening of the structure is obtained by an inner rod or the ends of the U-shaped tube that can be inserted into the junction of the two halves, secured with a screw, preventing bending in navigation.
  • Acrankshaft with two pedals and two symmetrical paddlewheels which are placed on the outer sides of both floats, propel the boat.
  • the crankshaft with pedals and paddlewheels can be placed on three symmetric pairs of notches in both floats, which let you select the most suitable position of the pedals for the user.
  • the simple steering control is a paddlewheel placed at one side in one of the floats, which is operated by a crank, enabling the rotation of the craft depending on the direction of rotation given to the paddlewheel.
  • These two U-shaped tube bars are responsible of rigidization and constitution of the structure, but in both folded and unfolded positions, as well as they are responsible of maintaining joined together both floats and of preventing its accidental folding at the same time.
  • This invention defined in claim 1, where the two folding platforms or halves are entirely manufactured in molded plastic, and the folding axis is placed into a big central transversal hinge.
  • the splitt floats can be manufactured in the same piece that these folding platforms or in separated pieces that must be attached later to them.
  • Another important difference is that the two U-shaped tube bars can be independent and not be mutually joined through a junction therebetween with screws as the previous invention cited.
  • each one ot these U-shaped tube metal bars can be independently movable along two planes placed at different heights, not necessarily in the same horizontal plane as the commented invention.
  • the pedals and the backrest are adjustable by longitudinal sliding of these two bars.
  • the U-shaped metal tube bars give rigidity to both folded and unfolded positions, and in folded position they give a handle for easy dragging and tranporting of the boat by land.
  • This invention can be converted into a trolley resembling a wheeled suitcase as a main feature by these U-shaped metal tube bars, and has a commmon rotation axis for the folding parts, for the transport wheels and for the rotation planes of the steering levers, simplyfing all the structure. All compacting and decompacting steps, and all adjusting steps to suit the passenger are all due to rotating and sliding movements of the pieces, so there are no detachable pieces (except the securing pins), so the folding and unfolding movements are quick and easy and the most of the elements are always joined during the use.
  • the described invention has several possible embodiments of the symmetrical U-shaped tube bars that can be manufactured, all of them with the same inventive concept.
  • Several drawings of one of the possible embodiments of the foldable pedal boat are shown from Figure 1 to Figure 18 , while Figures 19 , 20 , 21 and 22 show simplified sections for other possible embodiments.
  • the foldable boat has a single inventive concept in relation to its fixing system in folded and unfolded positions, but several compatible possible embodiments with this one, using the same parts and elements but changing the embodiment and placement along the boat. We describe in detail the most likely way of manufacturing and then later we will describe the rest of combinations based on the description of the first one.
  • the foldable boat consists, as shown in Figure 13 and Figure 14 , of two floating platforms or halves, front (1) and rear (2), which can be folded one over the other coincidentally, according to a middle axis (3) transverse to the boat. They are similar but not necessarily identical. Both floating platforms or halves (1) and (2) are made in one or several separated pieces (in this case properly glued, screwed, riveted or connected by any method, for obtaining a single rigid and robust structural unit). The most suitable manufacturing method for these two floating platforms or halves (1) and (2) would be the rotomoulding of plastic materials, in a single piece or in detached pieces that must be joined later. Both of these floating platforms (1) and (2) are symmetric in relation to a longitudinal vertical plane of symmetry passing through the center of the boat.
  • Both floating platforms or halves (1) and (2) have each one a middle central piece or platform, like a tray, a front one (4) and a rear one (5), both symmetrical in relation to the longitudinal vertical symmetry plane passing through the center of the craft, which serve as a junction or bridge for both symmetrical front floats (6) and rear floats (7), placed at the sides of each floating platform or half (1) and (2), respectively.
  • Both pair of symmetrical front floats (8) and rear floats (7) are symmetrical in relation to the longitudinal vertical symmetry plane passing through the center of the craft.
  • the central posterior bridge (5) or tray of the rear floating platform or half (2) have some moldings that prevent slipping (8) and serves as a seat for the passenger, having an appropriate shape for being comfortable when sitting in.
  • the central bridge or tray (4) of the front floating platform (1) can be smaller than the previous one, and serves as a union between the two front symmetrical front floats (6), as the central bridge or tray (5) of the rear floating platform or half (2) makes the same between the rear floats (7).
  • Floating platforms (1) and (2) have tubes (9) and (10) as common hinge, inside of which is inserted, transversely to the craft, a rigid and thick cylindrical rod (11), which gives the folding axis of the craft, which is fixed with a washer (12) and a pin (13), as shown in Figure 12 , Figure 13 and Figure 14 .
  • a washer (12) and a pin (13) As shown in Figure 5 and Figure 6 , when the boat is folded, the front floating platform or half (1) rests and coincides with the rear floating platform or half (2), touching between them on some parts of the floats or on attached elements or stoppers.
  • both pairs of symmetrical front floats (6) and rear floats (7) are aligned to constitute two elongated continuous side floats in the boat, making it a small foldable catamaran.
  • the hull shape in the junction between the front float (6) and the rear float (7) at each side of the boat is continuous and with no recesses or protrusions, giving a streamlined profile that makes the sliding of the boat in the water easy.
  • Each one has at its bottom, longitudinally and symmetrically, a keel-shaped thickening (14), which confers strength and resistance to impact or friction against the ground during transport, ending in a rearfin (15), fused to the rear float (7).
  • These fins (15) are responsible for efficient channeling of water flow to the rudder (16), to increase the maneuverability of a boat so small. They are reinforced to prevent breakage due to shock or friction with the ground, as they also serve to protect both rudders (16) when transported by land.
  • the bar (11) of the folding axis of the pedal boat threads by its ends two symmetrical steering levers (17), two equal and symmetrical lateral transport wheels (18) that protect the steering levers (17) from impact or friction to the ground when the boat is folded and dragged by land, and two friction washers (19) that smooth the movement of these steering levers (17).
  • two symmetrical U-shaped tube bars with rounded, square, rectangular or polygonal section, (front (20) and rear (21)), which may be hollow or solid, maintain aligned and rigidly fixed the two floating platforms or halves, front (1) and rear (2).
  • the front flotation platform or half (1) has at least a couple of pieces, bumps, protrusions or widenings of the float itself (22), placed on the inside, on the outside or on the top of the front floats (6), according to a different embodiment of the invention each.
  • Such pieces, bumps, protrusions or widenings of the float (22) are arranged symmetrically along the longitudinal vertical symmetry plane passing through the center of the craft. Each one of these pieces, bumps, protrusions or widenings of the float itself (22) is traversed lengthwise by a hole (23).
  • the central platform or bridge (4) of the front floating platform (1) is also traversed symmetrically by a pair of holes (24), performed longitudinaliy and symmetrically in relation to the longitudinal vertical symmetry plane passing through the center of the boat (on the inside, on the outside or on top of the front floats (6), according to the embodiment of the invention).
  • the rear floating platform or half (2) is also traversed by one or two pairs of parallel holes (25), longitudinaliy and symmetrically practiced in relation to the longitudinal vertical symmetry plane passing through the center of the craft (on the inside, on the outside or on top of the rear floats (7), according to the embodiment of the invention), with the difference that at least a pair of holes (24) and a pair of holes (25) are practiced at the same height.
  • the holes on the right side and on the left side of the boat are perfectly aligned, and are responsible of housing the front U-shaped tube bar (20).
  • the pairs of holes (23), (24) and (25) have all of them the same cross-section as both U-shaped tube bars (20) and (21).
  • the two arms of the front U-shaped tube bar (20) can be introduced consecutively so on through the holes (23), (24) and (25) at both sides of the boat. They can slide longitudinally to the boat between two limits made by two stoppers, but always keeping the two floating platforms or halves (1) and (2) unfolded and unable to be folded when their ends are inserted into the pairs of holes (25) of the rear floating platform or half (2).
  • the ends of the U-shaped tube bar (20) out from these pairs of hotes (25) the folding of the boat is allowed, at least by part of the front floating platform or half (1). This is shown in Figure 5 and Figure 8 .
  • the rear flotation platform or half (2) has at least a couple of pieces, bumps, protrusions or widenings of the float itsetf (26), placed on the inside, on the outside or on the top of the rear floats (7), according to a different embodiment of the invention each.
  • Such pieces, bumps, protrusions or widenings of the float (26) are arranged symmetrically along the longitudinal vertical symmetry plane passing through the center of the craft.
  • Each one of these pieces, or bumps, protrusions or widenings of the float itsetf (26) is traversed lengthwise by a hole (27).
  • the central platform or bridge (5) of the rear floating platform (2) is also traversed symmetrically by a pair of holes (28), performed longitudinally and symmetrically in relation to the longitudinal vertical symmetry plane passing through the center of the boat (on the inside, on the outside or on top of the rear floats (7), according to the emodiment of the invention).
  • the rear floating platform or half (2) is also traversed by one or two pairs of parallel holes (29), longitudinally and symmetrically practiced in relation to the longitudinal vertical symmetry plane passing through the center of the craft (on the inside, on the outside or on top of the rear floats (7), according to the embodiment of the invention), with the difference that at least a pair of holes (28) and a pair of holes (29) are practiced at the same height.
  • the holes on the right side and on the left side of the boat are perfectly aligned, and are responsible for housing the rear U-shaped tube bar (21).
  • the pairs of holes (27), (28) and (29) have all of them the same cross-section as both U-shaped tube bars (20) and (21).
  • the two arms of the rear U-shaped tube bar (21) can be introduced consecutively so on through the holes (27), (28) and (29) at both sides of the boat. They can slide longitudinally to the boat between two limits made by two stoppers, but always keeping the two floating platforms or halves (1) and (2) unfolded and unable to be folded, when their ends are inserted into the pairs of holes (29) of the front floating platform or half (1).
  • the front U-shaped tube bar (20) has a pair of pedals (30) housed in a pair of bearings (31) that are transversely screwed to the symmetrical arms of this front U-shaped tube bar (20).
  • the pedals (30) are joined to at least a single central paddlewheel (32), whose size allows the easy folding of the structure of the pedal boat by fitting into the space between the pairs of front floats (6) and rear floats (7).
  • the rear U-shaped tube bar (21) has two hinges (33) transversely screwed to their both arms, inside of which a bent rounded bar (34) is placed, which supports and allows to adjust the backrest (35) for suiting the passenger.
  • the front U-shaped tube bar (20) has in their both symmetrical arms a pair of vertical holes (36), equal and symmetrical to the longitudinal vertical symmetry plane passing through the center of the craft, and a pair of longitudinal slots (37), also equal and symmetrical to the longitudinal vertical symmetry plane passing through the center of the craft. Both into the pair of holes (36) and into the pair of longitudinal slots (37) a pair of pins (38) can be placed, that cross vertically the pieces, bumps, protrusions or widenings (22) of the pair of front floats (6). When the pair of holes (36) is crossed by the pair of pins (38), the front U-shaped tube bar (20) is blocked and can not slide longitudinally. If it is positioned in a way that their ends are not inserted into the pair or pairs of holes (25) of the rear floating platform or half (2), the rotation is not impeded and the foldable pedal boat can be folded around its axis (3).
  • the front U-shaped tube bar (20) can displace longitudinally in the direction of the boat a distance equal to the length of this pair of longitudinal vertical slots (37). This allows that the pedals (30) and the paddlewheel (32) can be adjusted to the size of the passenger but always with the ends of the arms of the front U-shaped tube bar (20) introduced into the pair or pairs of holes (25) of the rear floating platform or half (2), impeding the accidental folding of the pedal boat in navigation.
  • two small pivoting and / or sliding bolts or latches (39), symmetrically placed in both arms of the front U-shaped tube bar (20), can rotate and / or slide into some small hinges or supports (40), fitting into preset positions disposed in two rows of notches or holes (41), symetrically practiced on the inside, on the outside or on top of the pair of front floats (6), according to the embodiment of the invention.
  • the passenger uses both hands to unlock such pivoting and / or sliding bolts or latches (39) and pushes the pedals forward or backward by using the feet, locking then the front U-shaped tube bar (20) in the desired position.
  • the rear U-shaped tube bar (21) has in their both symmetrical arms a pair of vertical holes (42), equal and symmetrical in relation to the longitudinal vertical symmetry plane passing through the center of the craft, and a pair of longitudinal vertical slots (43), also equal and symmetrical in relation to the longitudinal vertical symmetry plane passing through the center of the craft. Both into the pair of holes (42) and into the pair of longitudinal slots (43), a pair of pins (44) can be fitted vertically, which can be introduced at time through the pieces, bumps, protrusions or widenings (26) of the pair of rear floats (7).
  • two L-shaped horizontal bars (45), that are bolted, riveted or glued to the rear U-shaped tube bar (21), have at their extremes two handles with locking pivoting and / or sliding devices that can be placed into two symmetrical rows of notches or holes (47), performed on the outer sides of the pair of rear floats (7).
  • These two symmetrical rows of notches or holes (47) fix the two L-shaped horizontal bars (45) in preset positions and adjust the backrest (35) in inclination. They can be easily catched by the passenger to unblock, move and relock the whole using both hands at once.
  • the two U-shaped tube bars front (20) and rear (21) can be joined by two ending plastic pieces (48), placed both of them at the transverse middle segment of the two U-shaped tube bars front (20) and rear (21).
  • These two ending plastic pieces (48) have a lock device for a secure joining and have a shape with a handle for dragging or pushing the folded pedal boat as a trolley or cart.
  • the backrest (35) is joined to the rear floating platform or half (2) by a straight bar (50) and an ending washer (51) with a pin (52) that crosses and threads it by using the tube hinges (53) and (54). The backrest (35) can then rotate freely around the axis provided by this straight bar (50) when the pin (52) is secured, but is always joined to the boat.
  • a pair of rear hooks (55) can be coupled and uncoupled to the supporting and adjusting bent bar (34) of the backrest (35), allowing the backrest (35) to be folded downwards when the boat is folding, making space for allowing the coupling of the paddlewheel (32).
  • the bearings (30) and the hinges (31) are screwed to the U-shaped tube bars front (20) and rear (21), respectively, and they can be used as stoppers for their longitudinal displacements. These elements stop in the pieces, or bumps, protrusions or widenings of the float itself (22) and (26), so unless they are unscrewed they prevent the U-shaped tube bars front (20) and rear (21) from releasing out from the pair of holes (23) and (24), and from the pairs of holes (27) and (28), respectively, and being lost.
  • the floating platform or half (2) have at each one of the stems of their floats (7) a vertical hole (56) for housing a rudder (16) which is confined on this position by a fixing piece that has an horizontal pulley (57).
  • a single a rope or string (58) connects the two horizontal pulleys (57) of both rudders (16) and the two steering levers (17), synchronizing all of them.
