Description

The invention relates to the construction industry of small vessels, and specifically to a folding kayak. Kayak (kauak) - this is one of the variants of a single rowing boat, the prototype of which is a boat, common among the peoples of the north. In Russia, the term “kayak” is also used to designate boats of this type. Modern kayaks are used for swimming on turbulent rivers, for rowing slalom, for the water rodeo (freestyle), for rafting and boating, for expeditions, for swimming on extensive reservoirs. Rowing on a kayak with a two-bladed paddle. The rower's seat is closed by a special apron, which does not allow water to enter the boat, which is fixed on the coaming, bordering the cockpit, in which the rower is located.

Known collapsible kayak, having a body made of flexible thin-walled shell of double curvature, the edges of which are connected in the area of the deck with each other and with a rigid part, having a cockpit-bordered cockpit for landing the rower. The bow and stern parts of the hull are sealed with outer covers. Inside in the area of the outer covers are traffic jams. Outer casing and plugs are attached to each other. Inside the case there is a rigid payol consisting of the central part, retractable fore and aft parts, as well as having side parts connected with coaming. Payol gives the body the necessary strength and rigidity. The middle part of the floorboard, located at the bottom of the hull opposite the cockpit, is intended for the positioning of the rower (NI 2283258 С2, МПК ВВВВ 7/06 (2006.01), 2006).

The flexible thin-walled shell, as follows from the above, forms a large part of the surface of the kayak's hull. To connect and seal the longitudinal joints of the shell located on the deck, linear three-slot clamps are used. The clamp consists of a body with longitudinal grooves into which the edges of the shell, fitted with shoulders, are inserted, and two expanders, with the displacement of which the grooves are compressed, fixing the edges of the shell. The coaming of the kayak is made collapsible with quick-disconnect couplings of its parts among themselves, with a shell and with three-slot clamps.

The presence of the shoulders on the shell complicates its manufacture, complicates the folding of the shell into a roll. For assembly requires several three-slot clips of complex shape. The design involves the use of payol complex branched design.

The known construction as a whole is distinguished by a large number of complex, non-technological parts, which, in a disassembled state, are quite difficult to assemble into convenient, compact luggage.

The problem to which the present invention is directed is to create a simple and technological, both in the manufacture and assembly of the collapsible kayak, the details of which can be packed as compactly as possible.

This task is solved by a collapsible kayak, which contains the bow and stern parts of the deck, made respectively with the front and rear parts of the coaming, the side parts of the coaming, rigidly connected with the front and rear parts of the coaming fore and aft parts of the deck with the formation of the cockpit, the hull formed from flexible shell, the edges of which are fixed on the sides of the fore and aft parts of the deck and along the lateral parts of the coaming, at least one rower seat, fore and aft sealing units to isolate the body cavity, and e inner flexible envelope disposed within the housing, at least in the cockpit area, opposite sides of which is rigidly secured to the side portions of the coaming.

In the best embodiment of the invention, the inner flexible shell is made with at least two reinforcing longitudinal elements located along the body at its bottom.

Also in the best mode for carrying out the invention, stringers are arranged telescopically in conjunction with the reinforcing elements of the inner flexible sheath inside the body at its bottom.

The folding kayak in the best embodiment of the invention is provided with a foot rest fixed on the stringers in the nose section of the deck, as well as pillers associated with the foot rest and nose part of the deck.

The bow and stern parts of the deck along the sides and the side parts of the coaming along it are preferable to perform with mating grooves, into which the edges of the flexible hull shell are inserted. With this design, the bow and stern parts of the deck and the lateral parts of the coaming may have openings located across the grooves that coincide with holes made along the lateral edges of the flexible hull shell. In this case, fastening elements of the flexible shell of the case are inserted inside the holes.

A folding kayak can have two flexible belts, on which on one of the sides of each are fastening elements of the flexible hull shell. These fastening elements can be made in the form of l-shaped protrusions oriented parallel ends of the flexible tape in the direction of its middle. Flexible tapes at the ends may have arcuate end fasteners located on one side of each tape with fasteners in the form of L-shaped protrusions and orientation

The folding kayak includes the bow 1 and the stern 2 parts of the deck (Fig. 1), made respectively with the front 3 and rear 4 parts of the coaming, the lateral 5 and 6 parts of the coaming, the body 7, formed from the flexible shell 8 (Fig. 2), the rower seat 9, the bow 10 and the stern 11 sealing units for isolating the cavity of the hull 7.

The lateral 5 and 6 parts of the coaming are rigidly connected to the front 3 and rear 4 parts of the coaming with the formation of the cockpit 12.

The edges of the flexible shell 8 are fixed on the sides 13 of the bow 1 and the stern of the 2 parts of the deck and along the side parts 5 and 6 of the coaming.

The flexible shell 8 is the main part of the folding kayak. Its edges 14 and 15 are made smooth with rows of holes 16 arranged along them. In the bow 17 and the aft 18 parts, the flexible shell 8 has cutouts. The flexible shell 8 is made with a gradually increasing width from the nose 17 to the middle and further also smoothly tapering towards the stern part 18. The flexible shell 8 has a small double curvature, i.e., curvature both in the longitudinal and in the transverse directions, but thanks to the smooth edges 14 and 15, not having any shoulder, protrusions, flexible sheath 8 can be easily rolled into a roll. When rolled into a roll, the deformation of the flexible shell 8 is limited to a uniformly distributed, smooth (without wrinkling) bend. Stretching or compressing areas of the shell slightly. Due to this, for the manufacture of a flexible shell 8 you can use a uniform elastic material without flexible inserts, which simplifies the design and increases the strength and rigidity of the body.

Inside the housing 7 in the cockpit zone 12 there is an internal flexible shell 19 (FIG. 3), the opposite sides of which are rigidly fixed on the side portions 5 and 6 of the coaming. In the particular case of the implementation of the inner flexible shell 19 can be made in one piece with the side parts 5 and 6 of the coaming.

The inner flexible shell 19 serves to reinforce the structure of the folding kayak in the cockpit zone 12, that is, in the landing zone of the rower, where the structure is subjected to maximum loads. Internal

- 2 013035 flexible sheath 19 can also be rolled up, but already in the transverse direction, i.e. parallel to the side portions 5 and 6 of the coaming.

The flexible sheath 8 of the housing 7 and the inner flexible sheath 19 may be placed one inside the other. Preferably, the rolls of the flexible shell 8 and the inner flexible shell 19 are approximately the same width.

The bow 1 and the stern 2 parts of the deck on the sides 13 and the side parts 5 and 6 of the coaming along are made with mating slots 20 (Fig. 4-6), inside which the edges 14 and 15 of the flexible shell 8 of the body 7 are inserted. Crosswise the slots 20 in the bow 1 and aft 2 parts of the deck and in the side parts 5 and 6 of the coaming are made holes 21 (Fig. 4), the location of which coincides with the location of the holes 16 at the edges 14 and 15 of the flexible shell 8.

Fastening elements 22, 23, 24, 25 (Fig. 5-9) of the flexible shell 8 of the housing 7 on the bow 1 and aft 2 parts of the deck and on the lateral parts 5 and 6 of the coaming, which are located on two flexible tapes 26 and 27 (Fig. 1) with a protrusion on one side of each (Fig. 7).

The fastening elements 22 and 23 are made in the form of L-shaped protrusions oriented at each flexible tape 26 and 27 by parallel ends 28 (FIG. 8, 9) in the direction of the middle of the flexible tape (26, 27). At the ends of the flexible tapes 26 and 27 are arcuate end fasteners 24 and 25, oriented in the direction of the l-shaped fasteners 22 and 23 concave parts.

Flexible tapes 26 and 27 are identical in design and are made in the form of a flattened tube of rubber or polyurethane (Fig. 10). The fastening elements 22 and 23 are rigidly fixed on the plates 29 (Fig. 8) or are made with the plates 29 in one piece. The plates 29 are located inside the flexible bands 26 and 27, and the fastening elements 22 and 23 protrude outwards. Similarly, the arcuate end fastening elements 24 and 25 are made, but on their plates 30 also adjacent L-shaped fastening elements 22 and 23 are fixed (FIG. 9).

The bow 1 and the stern 2 parts of the deck outside along the lateral sides 13 and the lateral parts 5 and 6 of the coaming outside are along the length with associated drowning 31 (Fig. 4), in which flexible tapes 26 and 27 are located.

In the process of assembling, L-shaped fastening elements 22 and 23 are inserted with bending of the corresponding flexible tape 26 or 27 sequentially one after another, starting from its middle, into the aligned holes 16 and 21, as shown in FIG. 11. Due to the fact that the distance between each flexible tape 26 or 27 and the parallel ends of 28 L-shaped fastening elements 22 and 23 is slightly less than the thickness of the bow 1 and the stern 2 parts of the deck and the lateral parts 5 and 6 of the coaming in the area of drowning 31 provides a tight reliable connection when turning the L-shaped fastening elements 22 and 23 with the orientation of the ends 28 parallel to the surface of the drowning 31. Moreover, each next mounted L-shaped fastening element 22 or 23 blocks the previous one from the self-ejection because the flexible tapes 26 and 27 of the section They are drowned in 31c with some tension due to the fact that the pitch of the holes 16 and 21 slightly exceeds the pitch of the flexible tapes 26 and 27 of the L-shaped fasteners 22 and 23. Arched end fasteners 24 and 25 located at the ends of the flexible tapes 26 and 27 can be easily inserted into the extreme openings 21 of the bow 1 and the aft 2 parts of the deck, since their bending radius corresponds to the distance between each of them and the adjacent L-shaped fastening element 22 or 23 located on the same plate 30.

The bow 1 and the stern 2 deck parts are each made from two connected parts 32 and 33 (FIG. 4), which mate with an overlap to ensure tightness. At the same time, on the length of the overlap of the bow 1 and the stern, 2 parts of the deck are made with aligned holes 34 and 35, into which the Fitted fasteners 22 and 23 are inserted, thereby ensuring a reliable connection of the parts 32 and 33 of the bow 1 and the stern 2 parts of the deck. Similarly, the bow 1 and aft 2 deck parts are joined to the side parts 5 and 6 of the coaming, which have projections 36 (Fig. 12) entering the holes in the front 3 and rear 4 parts of the coaming.

The inner flexible shell 19 is made with two reinforcing longitudinal elements 37 and 38, located along the housing 7 at its bottom. Inside the housing 7, stringers 39, 40, 41 and 42 are also located at its bottom, coupled telescopically with extension with reinforcing longitudinal elements 37 and 38 of the inner flexible sheath 19. Reinforcing longitudinal elements 37 and 38 are formed by Ω-shaped folds on the inner flexible sheath 19. A similar cross section has stringers 39, 40, 41 and 42, made of a rigid profile from a thermoplastic polymer material. The presence of reinforcing longitudinal elements 37 and 38, as well as stringers 39, 40, 41 and 42, increases the longitudinal rigidity of the collapsible kayak and, at the same time, due to the described design features, reinforcing longitudinal elements 37 and 38, as well as stringers 39, 40, 41, 42 prevent folding into a roll inner flexible shell 19.

The seat 9 of the rower is made with a hinged backrest 43 (Fig. 1). The seat 9 is fixed on the reinforcing longitudinal elements 37 and 38, and the backrest 43 is fixed on the side portions 5 and 6 of the coaming, which contributes to an increase in the structural strength of the collapsible kayak in the vertical direction.
