Description

This utility model relates to small-sized inflatable vessels with oar and sailing weapons and with devices for placing cargo on board, designed for rescue, tourist and sports purposes, fishing.

Known inflatable boat containing the outer shell and inflatable chambers installed inside the outer shell through connectors made in this shell in the form of cuts closed by fasteners, characterized in that at least part of the connectors are placed on the sides and / or ends of the boat, and the fasteners of these connectors are made in the form of loops placed along the edges of the connectors like teeth of zippers and attached to these edges, and the bars are removably inserted into the loops, while the bars are inserted into the loops with the possibility of releasing about grasping the bars of one or more loops of installing removable oarlocks, a removable transom when using an outboard motor or removable equipment when using sailing equipment, a tent, an awning, and the above oarlocks, transom or removable equipment are made with the possibility of fastening to the beams using fasteners or by nozzles on the beams using the through channels made in the oarlocks, transom or removable rigging, the walls of which cover the surfaces of the beams (patent RU 1277 U1, published on December 16, 1995).

The disadvantages of this inflatable boat include the presence of many duplicate elements that complicate the design and increase weight, the absence of a keel or dowels causes poor handling and stability on course, as well as a large drift when sailing.

A known inflatable boat with sailing weapons, including inflatable bottoms, rigid seats and a transom for an outboard motor, sailing weapons including a mast with a sail, sailing boxes with shverts and a steering device, the mast with a sail has a fulcrum on the floor of the boat and is secured with quick-release brackets located on one of the hard seats; the dowel boxes with daggers are pivotally fixed on the outside of the cylinders, can move along it and change the position of the center of lateral resistance (CBS) relative to the center of sail (CP) and the diametrical plane (DP), and the daggers move inside the dagger boxes and recline when hitting obstacles, the steering device has a mechanism for raising the rudder feather from the water and protecting it from possible damage when hitting an obstacle; it can be fixed in any possible place on the transom of the boat, including next to the outboard moto rum, (patent RU No. 81940, published April 10, 2009).

The disadvantages of this inflatable boat are:

- the use of rigid elements (dowels with dowels, a hard seat, transom and bottom) increases its weight and dimensions;

- cannot be used as a life-saving tool;

- a boom when moving from side to side when changing tacks is a threat to passengers who must dodge a boom;

- since when moving with side winds, only one dagger is working, its area should be doubled from the calculated one;

- the mast without cables experiences a large bending moment and, in this case, should have increased strength, and, consequently, mass or be used only in light winds;

 - the design of the dagger box with the dagger in case of collision of the dagger with an obstacle can lead to damage to the hull of the boat by fixing the dagger box;

- The design of the sail does not allow you to quickly remove it. The prototype for a utility model was an aviation boat

life-saving LAS-5M-3 with oars, three oars for oars, a direct sail and filling of the hull compartments from the carbon dioxide cylinder (TU 005291-83), which is produced in series. The LAS-5M-3 sailing armament consists of a direct sail with two pockets: a assembled oar is inserted into the horizontal pocket located on the top edge of the sail, which acts as a rhea, and a second oar shoulder blade is inserted into the vertical pocket located in the middle of the top edge of the sail. which is then attached to the top of the mast; the mast, which is assembled from two links of the second oar (handle and middle link), a mast extension (2 links) with three shafts for attaching the mast; steering oars (third oar).

The disadvantages of the boat LAS-5M-3 include:

- in order to fix the sail on the mast or remove it, you need to stand on the side of the boat at full height. When the sea is rough, this is dangerous, especially when the sail needs to be removed due to the increase in wind above the permissible (13 m / s) or other hazards, since due to a significant decrease in the stability of the boat, you can fall overboard and / or damage the boat’s inflatable balloons ;

- if the sheets are released voluntarily or involuntarily (this also happens), then the center of the sail rises and the overturning moment increases;

- quick discharge of the sail (with a squall) is difficult;

- a strong wind yanks the sail and tries to tear it off the mast, because of this, if pockets are loosely tied, the paddle blade and the oar (rhea) come out of their pockets;

- when tacking, changing the tack with the transition of the wind line by the nose (to the overstag) is difficult, and when a strong wind is impossible; a U-turn is possible only with the transition of the wind line aft (to the forewind); the turn into the fordewind comes with acceleration of speed and, with untimely braking of the turn, the boat slips the wind line to the overstag, which leads to a wind blow from the back of the sail and, as a result, capsize the boat (this happened repeatedly during training); in any case, coordinated work of three people is required when maneuvering, which implies a high level of training in the crew;

- the direct sail is driven by four sheets in fair winds and three in the opposite winds (the lower front is fixed in the front thruster);

- the fabric at the junction of the keel with the bottom experiences the greatest tension and breaks during strong winds (high dynamic pressure), which leads to water entering the cockpit of the boat;

- for luggage (stock of dry things) in the boat there is only one small waterproof bag and luggage rack for placing the rigging in the packed condition of the boat, which is not protected from water;

- the banding tubes are not located well - they can be closed by things; there were cases when people accidentally stepped on them and cut them off, injured their legs; it takes more than 5 seconds to clamp.

The objectives of this utility model are:

- improving the reliability and safety when setting and removing sailing weapons and controlling a boat under sail;

- increase the survivability of the boat;

- expanding the range of application of sailing weapons by wind force;

- improving the running properties of the boat;

- providing additional amenities to passengers;

- reducing the load on the structural elements of the hull.

The technical result consists in increasing comfort, reliability and safety and is achieved by the following technical solutions:

- the use on a boat of a set of sailing weapons, consisting of: sprint weapons (sprint mainsail and staysail) (Fig. 1); Spinnaker staysail (Fig. 2), which is made for winds up to 7 points on the Beaufort scale of a larger size, and for winds of 7-9 points - a reduced size (storm staysail-spinnaker).

- luggage on the sides of the boat;

- installation of a reinforcing scarf at the place of coupling of the keel with the bottom of the boat and a change in the design and mounting scheme of rigging;

- installing a reinforcing scarf and changing the design and installation location of the banding tubes.

In the claimed utility model, the hull of the serial boat LAS-5M-3 is taken as the basis. A bowsprit is installed on the bow of the hull of boat 1 (Fig. 3), which is necessary to ensure aero-hydrodynamic balancing of the boat when sailing. The bowsprit consists of the middle link 2 of the standard oar of the boat LAS-5M-3, the front hub 3, the rear hub 4 and a screw with an eye 5 screwed into the front hub. The bowsprit is inserted into the tube 6 made of strong fabric, the inner diameter of which is equal to the outer diameter of the bowsprit, the liner shank 4 is inserted into the lower eyelet of the front thimble 7 of the boat and secured with a cord 8. The bow of the bowsprit is fixed by the bridle 9: the loop of the bridle 9.2 is pulled through the hole 9.1 through the hole sleeves 3 and is thrown onto the sleeve 3 for a stranglehold, and the slings 9.3 are tied to the fastening loop of the mooring end 10 and two front loops 11 (right and left) of the boat's saving line. Tube 6 consists of stitched together tapes 6.1, 6.2 (for example, from nylon fabric with a width of 45-100 mm) and rubberized fabric 6.3 and horizontally

glued on the bow of the boat parallel to its longitudinal axis. For the convenience of threading the bowsprit, ribbon 6.4 is sewn into the tube.

The mast (Fig. 4) consists of six links: three links 10.1, corresponding in diameter to the handle of the standard oar of the boat LAS-5M-3, and three middle links 10.2 of the standard oar of the boat LAS-5M-3. On the upper link 10.1 in its upper part, a clamp 10.3 (product LAS-5M-3) with two hooks is fastened, which in the working position are attached to the side oarlocks by a boat assembly. The links of the mast are interconnected in a known manner using the clamps 10.4, connected to the links with a cord 10.5. At the top of the mast there is a top 11 (Fig. 5), in which there is a hole 12 for the halyard of the sail (in a particular case, for sprint armament - two holes) and two holes 13 for attaching a circular light (it is not the subject of this utility model). The lower sleeve 14 of the top 11 has a diameter equal to the inner diameter of the link 10.2, and the upper sleeve 15 - the inner diameter of the link 10.1.

Sailing sprint armament (Fig. 6) consists of a sprint mainsail 16 and a staysail 17. The main mainsail has a pocket 18 on which the mast 10 is threaded. In the middle part of the pocket there is a clamp 19 with a thrust bearing into which the handle of the boat’s oar, which functions a sprint 20, the blade of which is inserted into a pocket 21 sewn onto the mainsail. In a particular case, the sprint is assembled from three separate parts of the oar: 10.2, 10.1 and 10.2, for placing which on a sail a pocket is sewn along the entire length of the sprint. The total length of the front crib of the mainsail is equal to the length of the four mast links assembly. The sheet of the grotto was passed through the eyelet 22 of the kousha glued to the center of the rear can of the boat. The staysail 17 on the lower side has a pocket 23 in which a boom is assembled, assembled from two links of a standard boat oar. In the front corner and at a distance of 20-30% of the length of the lower staysail cradle, loops with carabiners 24 are sewn for fastening to the ear of the 5th screw screw or to the front thruster of the boat

(Depends on the loading of the boat and the angle of travel to the wind). Halyards of the staysail and mainsail, passed through the openings 12 of the mast top 11, in the working position are secured with clew assemblies on the front side thimbles. To provide visibility to the helmsman, windows 25 are made of transparent soft plastic. Vantins mounted on clamp 10.3 are attached to the side oarlocks by a boat assembly in the working position.

Sailing equipment with one sail consists of a staysail-spinnaker. The opening of a larger spinnaker staysail designed for winds up to 7 on the Beaufort scale is shown in FIG. 7, and for winds of 7-9 points - a reduced size (storm staysail-spinnaker) - in FIG. 8. We reveal the initial sphericity of the upper part of the spinnaker with a radius of 5-10 meters, which ensures an increase in the aerodynamic drag coefficient of the sail and, as a result, an increase in the pulling force. Other forms of the staysail-spinnaker can also be calculated, but subject to the following conditions: the sail is symmetrical about its longitudinal axis; the length of the side lifters is not more than the distance from the top of the mast to the nose of the bowsprit; the minimum angle of the pennant wind is 40 degrees (reason: a large frontal resistance of the boat's hull with relatively low lateral drag and a large windage of the boat's hull with passengers). The reinforcing tape sewn to the joint of the panels and around the perimeter forms a bridle 26, below which a pocket 27 is sewn with a plate sewn into it. Loops are formed on the lower sail hoop in the center and at the corners of the reinforcing braid, into which steel rings 28 are sewn for joining sheets. A similar ring is dressed in a bridle to attach the halyard. To provide visibility to the helmsman, windows 25 are made of transparent soft plastic.

The technical result of creating additional amenities for passengers and reducing the load on the structural elements of the hull is achieved by the rational placement of luggage and passengers

(Fig. 9). On the bow of the hull are fixed two pockets 29 and 30 for technical and medical first-aid kits; 4 fasteners 31 for waterproof bags 32 are glued on the sides (for example, each waterproof bag consists of one outer bag with a diameter of 250 mm, a length of 1500 mm, and two inside ones, with a diameter of 245 (+0, +3) mm, a length of 750 mm); luggage mounts with four or more half rings are glued on the aft fairings; a waterproof bag 34 is installed on the bottom, which is attached to the hinges on the sides of the boat; full-time trunk 35 is used for its intended purpose. This arrangement of luggage frees up the cockpit and allows the crew to relax while lying down; significantly reduces the voltage at the interface between the bottom and the hull of the boat, reduces its drag.

The LAS-5M-3 boat experiences the greatest tension in the connection unit (Fig. 10) of the seat (front can) 36, bottom 37, keel 38 and keel shaft 39. This dangerous drawback is achieved by installing a reinforcing headscarf at the junction of the keel with the bottom of the boat . The reinforcing scarf consists of a rigid insert 40 (for example, hard rubber, textolite or nylon), a cord 41 glued and sewn with panels of rubberized fabric 42, 43 and rubberized tape 44, which are glued T-shaped to the bottom from the bottom and to the keel on the right and left.

In the claimed utility model, three banding tubes 45 (Fig. 11) are located in the outer upper sector of the inflatable balloon of the boat hull 1. The banding tube contains a ball valve 46 with a control handle 47 and is covered by a safety valve 48 fastened to a ball 49. In the open position of the crane, the handle is located along the tube. The handle when the valve is in the closed position is perpendicular to the tube and does not allow the valve to be closed to the bulb. In the particular case, when using the boat for tourism, sports and fishing, the hull of the boat is made without a gas filling system from a cylinder with carbon dioxide and is filled from a hand pump (known product); as an option, the body can be made without a standard front trunk, banding tubes and a safety valve (in various variations); at the same time, the fittings for blowing the compartments are installed on the inside of the cockpit to provide easy access to them.

The proposed design of the sailing armament of the boat:

- allows you to collect and remove the sailing armament of a boat in the water without getting up to its full height (while sitting);

- provides the movement of an inflatable boat under the influence of wind, including at an angle to the headwind;

- provides acceptable aero-hydrodynamic balancing of the boat at any load, both with sprint armament and under the staysail-spinnaker;

- provides quick (emergency) “dumping” of the sail in case of need (it is enough to untie the clew assembly of the halyard of the sail with one jerk);

- reduces overturning moment due to lower center of sailing;

- allows you to reduce the load on the mast and the hull of the boat due to its redistribution to the bowsprit with a bridle, oarlocks, thimbles and lump jar.

The proposed rational arrangement of luggage allows you to evenly distribute the load on the hull of the boat, free up space in the cockpit and increase the comfort of the boat, as well as improve its balance when moving, both with tail and headwinds.

The installation of a reinforcing scarf in the junction of the bottom and keel allows you to repeatedly reduce the load on the boat’s tissue, both from the vertical load and from the drag of the keel due to an increase in the area of the fabric that perceives the load.

The bowsprit can be assembled and installed when the boat is both ashore and afloat.

Sailing weapons are assembled after the boat exits to a depth exceeding the draft of the boat with the keel, and begins with the installation of the mast. To do this, the first oar assembly is inserted into the stern oarlock, the scapula is disconnected from the second oar and the two assembled links 10.1 and 10.2 are inserted into the keel shaft (from this moment the boat becomes steered with tailwinds). After that, four mast links are assembled, the top of the mast 11 is fixed and the halyard of the sail (both halyards with sprint armament) is brought into the holes 12 of the mast top; the mast is connected to the previous two links and the cabs are attached to the side oar of the boat by boat nodes; then the sails are raised, the sheets are selected and the boat lays on the set course.

Tests in the Caspian and Baltic Seas showed that with a crew of 1-2 people it is preferable to raise sprint sails, since with such weapons the boat is easily controlled by one person; with a crew of 2-5 people - use a staysail-spinnaker. The maximum wind at which the large staysail-spinnaker rose was 8 points. At 9 points, a storm staysail-spinnaker (wind to the backstage) was used.

Tests have confirmed the industrial applicability of the utility model. The second link of the mast below 10.2 is most susceptible to damage. It is used repeatedly both in the mast itself and in the bowsprit, sprint and oars. The interchangeability of parts increases the reliability of the utility model as a whole.
