Description

Portable boat

Technical Field

The invention relates to a foldable portable boat, and belongs to the field of ships.

Background

Outdoor sports, leisure and health preserving, emergency and disaster relief and fishery culture, and a small portable boat is needed.

In the past, relatively more inflatable boats were used, but the disadvantages of the inflatable boats are obvious, such as long inflation and deflation time and easy penetration of sharp stones or tree branches.

The rotational molding manufacturing technology of thermal forming and the molding manufacturing technology of glass fiber resin further promote the upgrading of hard boat and kayak products, but the problems of difficult transportation and inconvenient storage always exist.

Therefore, solutions to the above problems are emerging and classified into the following two categories:

the first category is canoes and KAYAKs with skin-fitted frames made of wood, aluminum or fiberglass materials, joined to each other by connectors to form a frame-type frame, covered with a flexible and waterproof covering sewn and glued to the frame, previous patents describe U.S. Pat. No. 4,702,193 to Michael P.Jones and Paul M.Hahn (title: CO LL APSIB L E BOAT, 1987), U.S. Pat. No. 4,841,899 to Karen Fleckles and Kolight W.Aberhy (title: KAYAK FO L DING, 1989), U.S. Pat. No. 5,875,731 to Dlight W.Aberheen and Gordon E.Espeeth (title: CO LL AP L E BOAT, 1999), U.S. Pat. No. 5,680,828 to Joseph J.Totten (title: KAYAK, 1997), U.S. Pat. No. Gondy (title: CO LL APSIB, 97 to Gondy; U.S. Pat. No. 7 to Joseph J.J.Totten) (title: 19: WO 38: Guiney) (title: U.S. Pat. No. 7,36 to No. 7,857,36 to Green).

The first category of canoes and kayaks has the advantage of being relatively convenient to transport and store. However, the number and kinds of the components constituting the frame are excessively complicated, the assembly process of the frame is complicated, and it often takes a long time to assemble and disassemble the frame. The flexible skin is contacted with the water body, so that larger fluid resistance is generated, and personal danger is caused by scratching and lacerating easily when the flexible skin is contacted with reefs and sharp objects.

The second category is the use of double or corrugated panels of hollow or honeycomb structure, WITH special crease lines in the panels to assemble and fold the panels and then mate fasteners to form the hull, previous patents are described in U.S. Pat. No. 4,706,597 to Frank M.Flgon (title: SEAM L ESS FO L DAB L E BOAT 1987), U.S. Pat. No. 4,911,095 to Alex R.Kaye (title: CO L APSIB L E BOAT WITH REMOVAB L E TRANSOM PANE L1990), U.S. Pat. No. 6,006,691 to Stephen E.Wilce (title: KNOCK-DOWN BOAT ASSEMB B L Y1999), U.S. Pat. No. 6,615,762 to William S.Scott (title: DAB L E2 CONSTON SYSTEM 2003 6326, 1999), and U.S. Pat. No. 6,615,762 to William SAGE K275968 to KAY 2711, KAY BIPOL AS BIAT 8,316,788, KAY BIAT 278 to BIO BIPOL BIO 638, KAY BIAT 8,316,788, KAY BIO BIAT 8,316,788, KAY BIAT year.

Both of the 6,615,762 patent and the 8,316,788 patent relate to a synthetic resin corrugated sheet as a material for kayaks. Although kayaks and canoes are small boats, they are still quite different in their structure. Seen from the transverse section of the kayak, the kayak is formed by enclosing a bottom plate, side plates and a deck at the top, and an enclosed tubular space is a passenger cabin and is often matched with a waterproof wave-proof skirt to strengthen the waterproof sealing effect. In contrast, the canoe is a non-closed open shape with an upward opening at the top, including side panels, a bottom panel and no top deck, and has a lower rigidity in the longitudinal and transverse directions than a kayak having a tubular closed space, and it is difficult to maintain the structural stability, and the reduction of the thickness of the hull plates for the purpose of reducing the overall weight makes it more difficult to enhance the overall strength.

105,164,013, the bulk of the overall storage and transportation of the entire ship is increased by the large number of multi-section gunwale frames and the plurality of U-shaped removable ribs and the second layer of reinforced floor. The complex assembly process and numerous connectors are also very user proof, increasing the likelihood of assembly errors and damage.

Detailed Description

The above and other objects, features and advantages of the present invention will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings.

The processing technology of the folding board, especially the processing technology of the plastic board has many kinds, for the ordinary products of the board with small gram weight, generally adopt the carton to make the sample machine or the platform die cutter to process the board, the former carves or presses the crease pattern on the board, the latter presses the crease pattern with the mould; for high-strength products with large gram weight plates, a high-pressure press is often adopted to press creases in sections, and a heating auxiliary forming and hot-melting edge sealing device is arranged. In China, such as China, Japan and Korean, small-lot processing is often performed mainly by hand.

The plastic plate is made of modified polypropylene plastic, the folding-resistant times of the plastic plate can reach thousands of times, the plate structure is divided into a solid structure and a hollow structure, and the hollow structure is commonly provided with a hollow plate and a honeycomb plate.

Although the hollow plate material has excellent section strength, the conventional canoe has low rigidity in the longitudinal and transverse directions, and is difficult to bear large load and high strength.

When the boat is folded into the boat-shaped state, the turnup inward-rolling plate structure is arranged, so that the light boat which cannot have the integral tubular structure peculiar to the kayak has the cross section which is formed by the turnup inward-rolling plate structure and has an inward-turnup structure, an inverted triangular structure, a groove-shaped structure with a downward opening or a tubular or cylindrical structure. These configurations are a combination of several factors, including how many of the N tuck fold lines are, the manner of continuous rotational folding, and the manner of attachment of the fastener 802. The structure of the ship side line and the turned-over inward-rolling plate enables the extending part of the upper edge line of the ship side plate of the light boat to have the structure which is equivalent to the side longitudinal keel at the left side and the right side, and is assisted by the middle connecting piece woven belt for connecting the left side and the right side of the ship side plate, so that the longitudinal rigidity and the transverse rigidity of the light boat are improved, and the portable light boat shows good structural strength.

It should be noted that the process of switching the single sheet between the boat-shaped state and the storage state is actually a reversible two-way switching process of manual folding or unfolding, and the following drawings show a partial folding or unfolding one-way demonstration process, and in actual operation and implementation, the process should be regarded as a complete two-way reversible process.

The first embodiment shows the implementation of the folding boat mainly based on manual paddle without propeller thruster, and the second embodiment shows the implementation of the folding boat mainly based on manual paddle with propeller thruster driven by electricity or gasoline and diesel oil and its mounting fixture. The second embodiment is realized by adding and replacing part of the device on the basis of the first embodiment, so that the implementation mode of the second embodiment only shows the added and replaced part of the device.

Fig. 1 is a first embodiment of the present invention, shown in a flat, stretched condition, with a single sheet of material having surface crease lines, and shown with a numerical indicia applied thereto. The outer contour of the plate is generally cut by a customized cutting die, wherein the seams among 101, 102, 103, 104 and 105 are the seams for cutting and penetrating the plate, and the width of the seams is 2mm-28 mm; the boat side plate comprises plate materials 401 and 402, wherein the ship collecting fold line group is an isosceles triangle axisymmetric fold line group of the boat side plate, when the ship collecting fold line group is symmetrically folded in half and is changed into a closed state, the longitudinal length of the ship on the port line is reduced, the

ship

101, 102, 103 and 104, 105 and 106 are partially overlapped, and

ship collecting fasteners

805, 806 and 807 are arranged at the overlapped part for fixing the structure and locking the longitudinal length. At the same time, the

folds

601 and 602 at the upper edge line of the boat side plate are also partially overlapped, and the two lines are combined into a crease line, namely the crease line at the upper edge line of the boat side plate in the boat-shaped state. In the same principle, the flanging inner-

roll crease lines

701 and 702 on the flanging inner-roll plate and the boat side plate upper edge crease lines without intersection points are also partially overlapped, and the two lines are combined into one crease line, namely the flanging inner-roll crease line in the boat shape state. In the unfolded and flattened state of the sheet material in fig. 1, the

creases

601 and 602 of the upper line of the boat side plate are two lines which are staggered, and the turned-up inner

fold crease lines

701 and 702 are also two lines which are staggered, but once the folded-up crease line group is folded symmetrically and folded to be in a closed state, the folded-up

fasteners

805, 806 and 807 are folded and fixed, and the

group

601 and 602 become one crease line, 701 and 702 are also the same. For reference, it can be seen in fig. 7, 8, 9 that the two lines are merged into one line, which ensures the possibility of the flange inner wrap sheet material being bent according to a predetermined rotation.

Fig. 3 is a view of a single sheet of material folded into a six-sided box shape with an approximate rectangular parallelepiped outline, identified as a dotted area, of a folded-over inside-roll sheet structure according to a first embodiment of the invention. At this time, the portions where 101, 102, 103 and 104, 105, 106 overlap have been fitted with the port-closing

fasteners

805, 806, 807. This is a boat body divided into nine parts in the longitudinal direction, and has been converted into a storage state of a box body having a six-sided outer contour by folding or unfolding along folding surface folding lines.

Fig. 4 is a view showing a first embodiment of the present invention, which is a view showing a process of converting a single sheet material into a canoe shape with an upward opening top by unfolding and folding the sheet material from a six-sided box shape having an approximately rectangular parallelepiped outer contour. The figure is marked as a block with a point shape and is a plate with a flanging inner-rolling plate structure. The longitudinal direction of the canoe is divided into nine parts, the four parts on the left side of the figure and the four parts on the right side of the figure are gradually separated.

Fig. 5 is a view showing a second process of converting a single sheet into a canoe shape with an upward opening top by unfolding and folding the sheet in a six-sided box shape having an outer contour similar to a rectangular parallelepiped according to the first embodiment of the present invention. The figure is marked as a block with a point shape and is a plate with a flanging inner-rolling plate structure. The longitudinal direction of the canoe is divided into nine parts, the four parts on the left side of the figure and the four parts on the right side of the figure are completely separated.

Fig. 6 is a view showing a third process of converting a single sheet into a canoe shape with an upward opening top by unfolding and folding the sheet in a six-sided box shape having an outer contour similar to a rectangular parallelepiped according to the first embodiment of the present invention. The longitudinal direction of the canoe is divided into nine parts, the four parts on the left side of the figure and the four parts on the right side of the figure are completely separated. At this time, since the fold line group has been symmetrically folded to become a closed state, the

fasteners

805, 806, 807 are installed at the overlapped portions of 101, 102, 103 and 104, 105, 106, so that the plate material cannot be spread out to a flat state. In general, the

port closing fasteners

805, 806, and 807 are not loosened after they are fixed, in other words, the

port closing fasteners

805, 806, and 807 are always in a fastened state in the canoe state or the stowed state. The boat comprises a boat body, 8 plates penetrating through the left side and the right side of the boat body and formed by zigzag connecting lines formed by connecting line segments, and the 8 transverse creases divide the longitudinal length of the boat body into 9 parts, so that the boat is beneficial to folding the light boat in a smaller storage state.

Fig. 8 is a view showing a fourth process of converting a single sheet into a canoe shape with an upward opening top by unfolding and folding the sheet in a six-sided box shape having an outer contour similar to a rectangular parallelepiped according to the first embodiment of the present invention.

Under conventional conditions, a heavy object put into the transport case transfers the weight to the transport case, and the shoulder straps on the transport case transfer the weight to the carrier. However, for a relatively heavy boat, the transfer of weight through such an intermediate medium as a thin transport case may cause the transport case to break quickly. The purpose of setting up such bearing system is in order to give the person of bearing the back with the most direct transmission of the weight of the boat body that is relatively heavier, let the transport box body as sheltering from the wind and keeping out the rain and block the protective screen that scratches to a great extent. Under the thought, the braid is concentrated from the through hole 964 on the canoe and is penetrated out of the transport case from the through hole 965 on the upper half part of the transport case and is fixed to the lower half part of the transport case, the canoe and the braid form a closed annular structure together to transfer the weight to a person carrying the weight, so the through hole 964 on the canoe is used as a lifting point of the weight, the height of the through hole 964 should be lower than that of the through hole 965 on the upper half part of the transport case, and the through hole on the upper half part of the transport case does not bear large force.
