Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to improving the stability of small boats with outboard mowers, and more particularly to preventing the stern of an IK boat from being too submerged when the boat is moving forward. The invention relates to a boat having a flap for use in the boat.

When a small boat fitted with an outboard motor is propelled forward by the outboard motor, the stern of the boat tends to sink deeper into the water, causing the stern to rise accordingly. This condition is generally not desirable. This is because the rose tries to continue descending after rising, causing the boat to pitch. Boating becomes uncomfortable and stability is reduced.

This problem is most apparent when an outboard motor is used on a collapsible boat of the type disclosed in U.S. Pat. No. 3,482,668. This type of boat has a number of hinged panels that move from a side-by-side folded position to an assembled position. And in the assembled position the bottom of the boat is the first
The sides of the boat are formed by a pair of panels, with a second
It is formed by a pair of panels. Such boats are lightweight to operate and can be easily assembled into working condition by one person. Installing an outboard motor on such a boat will yield good results if the motor weight does not exceed approximately 13.7 to 4 f (30 bond). For example, a 4 horsepower class or higher motor is clearly too large for use in such a boat due to the problems discussed above, especially when a single person is seated at the rear of the boat.

Because of this problem, structures are required to be added to the boat to substantially eliminate the problem and allow the boat to be used safely and comfortably at the required speeds. Canada has advanced technology! Includes Patent No. 94038.9.

The present invention satisfies the aforementioned needs by attaching a pair of flaps to the bottom panel of the hoard.

This panel may be constructed in any of several different embodiments, and the purpose of this flap is to provide drag to the boat, or to provide a flat surface therefor. As such, the flaps stabilize the boat so that the stern of the boat has virtually no tendency to sink too deeply into the water as the boat is propelled forward by the power of the outboard motor. In this way, the boat remains substantially level, is easier to maneuver, and can travel at higher speeds with minimal discomfort to the boat's occupants.

A first object of the present invention is to provide a boat having flap means which maintains the boat substantially horizontally in the water and which prevents the boat from turning when the boat is moving forward in the water. Prevent it from falling. This eliminates stability problems and allows the boat to go faster without causing discomfort to the boat's occupants.

Another object of the invention is to provide a collapsible boat having a pair of bottom panels. The bottom panel is
Each has a flap that provides drag near the stern of the boat while the boat is moving forward, or provides a flotation plane to maintain the stern relatively high in the water. This eliminates problems caused by the stern dropping, for example when an outboard motor is used on this bow 14.

Embodiments of the present invention will be described below with reference to the drawings.

The invention applies to boat sterns, particularly when the boat is driven by an outboard motor near the stern, to prevent the stern from sinking too deeply into the water while the boat is moving forward. As can be seen, the present invention is disclosed with respect to a collapsible boat 10 of the type disclosed in U.S. Pat. No. 482,368.

The boat is shown in assembled form in FIG. 6, with a pair of side panels 12.14 and a pair of bottom panels 16.14. '1
It has 8. /ξThe channels 12 and 16 are the first hinge line 2
panels 14 and 18 are hinged along a second hinge line 22, and panels 16 and 18 are hinged along a second hinge line 24; Connected in a hinged manner. The panels of boat 10 are formed from a resilient sheet material such as polyethylene and have a thickness of approximately 0.25 inches.

In the assembled state, plates 26.2B, 50 are aligned as shown in FIG. It is inserted between the panels 12 and 14 to keep the panels 12 and 14 convexly arched outwardly and to separate the panels 12, 14 from each other. The nominels 12, 14 tend to return to their folded or inoperative position due to their elasticity. In this way, the panel 12.14 exerts a longitudinal force on the plate 26.28.30, holding the plate 26.28.30 in position by stiffness. By removing these plates, the boat folds into a compact configuration as shown in FIG. Only panel 16 is shown in FIG. 1; other panels are not shown in FIG.
and on the opposite side of panel 16. However, hinge lines 20.24 are shown in FIG. In FIG. 2, the boat is shown assembled with the panel 12, hinge line 20.24, with the panel 12 shown along the nominal line 16.

Boat 10 is used with a meth 5 or an outboard motor.

If a motor is used, it can be attached to the stern 32 of the boat and the boat can be driven forward by the motor.

The problem that arises with using a large enough motor, for example a motor weighing more than about 13.7kp (30 bonds), is that as speed increases, the boat's stern rises while the boat's stern increases. It is to begin the descent. This results in a decrease in stability and makes boating uncomfortable for the boat's occupants. therefore,
The present invention provides a flap system for boats, particularly boats 1 o VC, that eliminates this problem and provides a means of holding the stern relatively high in the water.

That is, it provides a means for maintaining the boat substantially level in the water, especially when only one person is on the boat.

A first embodiment of the flap system of the present invention is shown in FIGS.
As shown in FIG. The system has a pair of flap filters 4 having a front edge 6 and a rear edge 8. Each flap 64 has an outer edge 40 and an inner edge 42. Each flap ('!) has an outer edge 40 and an inner edge 42.

It is secured to the bottom surface of the corresponding bottom panel of the 7] (7) by a fastener 44 near its trailing edge 68.

The edge 42 of each flap is proximate to the hinge line 24 as shown in FIGS. 1 and 4, and the edge 40 of each flap extends specifically in the longitudinal direction of the curvature of the hinge line 20 as shown in FIG. .

The flap filter 4 is made of a suitable material such as polypropylene. In the retracted position, each flap 34 generally contacts the bottom of the boat, as shown in FIG. However, when the boat car moves in the i\iJ direction, the forward thrust of the boat attempts to raise the water flap to the position shown by the broken line in FIG.

When the flap is in this position, there is a drag force exerted by the flap for about 4 days, and this condition makes the stern relatively high in the water. Just like that, flap 4
The drawn position force ray/movement to the moving position is responsive to the motion of the boat in the water. When the speed of the moon sort is reduced to a negligible value, the flap is shown by the solid line in Figure 2. The retracted position π almost returns.

The strap means 41 of FIGS. 5-8 is used to removably mount a folded boat on the roof of a motor vehicle 42, and can also be used to hoist the boat by hand, as shown in FIG. The band means 41 includes a central band 44 and a central band 44.
It has a pair of end bands 46 through which the ring passes. The ends of each number 46 have hooks 48 as shown in FIGS. 7 and 8 for removably attaching the strap to the rain gutter on both sides of the vehicle 420. Since a trapping type buckle 49 of a conventional structure is provided in each number 46, the length of the belt is
It is adjustable for use in the manner shown in FIGS.

When used in the manner shown in FIG. 6, each number 46 is connected to the end hook 48 and the strap forms a loop around the boat as shown in FIG.

Additionally, the length of the strap 44 is adjustable for use in the method shown in FIGS. 5 and 6. In particular, the band 44 is divided into two segments (44a, 44bK) as shown in FIG.
It is formed. The cover 45 is supported by a sash 44a, and a band means 41 provides a cushioning effect so as not to cause discomfort to those wearing the jacket.

A second embodiment of the flap system of the present invention is shown in FIGS. 9-11 and includes a pair of generally rectangular flaps 60 shaped as shown in FIGS.

Each flap 60 has a forward edge 62, a rearward edge 64, and a pair of lateral edges as shown in FIG. Each flap 60 has a fastener 7 near its forward edge 62.
Fastened by 0, h, fasteners on bottom panel 16.1
8 (see Figure 6).

The flap 60 is formed of a suitable resilient material, such as a polypropylene sheet approximately 0.25 inches thick. In the retracted position, the flap 60 is in the solid line position in Figure 10, where there is a 7" rearward and upward extension from the bottom nominal 16. The actuated position (dashed line position in FIG. 10) can be moved by moving from the solid line position in the figure to the dashed line position, and each flap 72 has a tab 74 at its lower end. 60 grooves 76
is received in frictional engagement within. This attachment holds the flap 60 in the position shown by the dashed line in FIG. 10, and allows the flap 60 to form a plane for floating the boat when the boat is driven through the water by an outboard motor attached to the stern filter 2 of the boat. . The flotation effect of the flap 60 allows the stern to be relatively high underwater! to keep the roses relatively low in the water.

This increases the stability of the boat and allows the occupant to ride the boat more comfortably when there is only one person on board.

The flap 60 is also positioned as shown in FIG. 16 in the activated position, which is the position in which the flap 60 is held by the smaller flap 72. Each small flap 72 has a pair of through holes that allow water to pass through without exerting a substantial rearward force on the 7run. A small flap is attached to the bottom panel 16 by a zipper 76.
．． It is fixed at 18.

FIG. 12 shows a modification of the FranPro 0. In this figure, the flap 60a is made of a single piece and has a lower, main segment 61 for floating the boat. A second, upper segment 63 is hinged to segment 61 at a rearward position 65. A sixth segment 67 is hinged to segment 66 at location 69. Pin 71 is removably secured to the adjacent bottom of the boat and removably secures segment 67 to the boat with main segment 61 in the operative, planar position shown in FIG.

When pin 71 is removed, segments 6 and 67 are straight and substantially extend with segment 61. Water pressure on flap 60a forces it upwardly. At the same time, the bottom panel of the boat is pushed against the adjacent bottom panel, and there is no effect of floating up from the water surface.

A sixth embodiment of the flap system of the present invention is shown in FIGS. 16-15. This flap system is integral with each other and has a central band 82 as shown in FIG.
It has a pair of generally rectangular flaps 80 forming a . The band 82 is closed using the zipper 84 or other means)
10 on its hinge line 24, and the flap 8 relative to the boat as in the case of the flap filter 4°60 described above.
There are no other concatenations of 0. In this way, the flap system of FIGS. 13 to 15 has a turret part structure of 7r,
For example, it is made of an elastic material such as polypropylene. A typical thickness of the flap 80 is o665CTL (0.25 inches).

The elasticity of the flap 800 causes the flap 8o to substantially contact the other surface of the panel 16, as shown in FIG. 16, when the boat 10 is folded. However, when the boat is assembled in the operating position as shown in FIG. 3, the flap 80 extends laterally outwardly of the hinge line 24 at a distance from the bottom panel 16.18 as shown in FIG. Exists. As a result, the 7-lap 80 is in a position very similar to the position of the flap 60 in FIGS. 10 and 11, except that the flap 80 protrudes slightly downwardly from the bottom panel 16.18, probably due to its elasticity. is usually o. In any case, in the actuated position, the flap 80 is
When the boat 10 is attached to the stern 62 and propelled by the outboard motor, the stern of the boat is positioned relatively high in the water.

Tips to assist in installing the outboard motor on the boat: 1. The boat 10 has a fixed plate 9o (see FIGS. 16 and 17).
(see figure). Plate 9o is attached to bottom wall 16 by fasteners 92.
．． The rear end 1 of 18 is determined by 1. As can be seen, the flap 6o is shown in FIG. 16 and the lamp 7 is held in the operating position by the second flap 72.

In order to strengthen the bond between the plate 90 and the board 10,
A fixing placket 94, preferably of metal type, is attached to the fastener 9.
Note that it is installed in 10 by Bo). Bracket 94
has a lower 7 flange 98 and an upper flange 100.

The lower 7 langes 98 extend along the inner surface of the bottom panel 16.18 of the boat, and the upper flange 100 extends along the inner surface of the plate 90 and is secured to the plate 90 by fasteners 102. In this way, the outboard motor
and 7 langes 100 and W can be securely fixed, thereby making it more securely connected to the boat. The connection of the side flanges 95 of the brackets 94 ensures that downward forces can be applied to the plates 90 while holding the plates 90 in a fixed position with respect to the boat.
