Description

[Detailed Description of the Invention] The present invention relates to a bottom plate that is assembled on the bottom cloth of a rubber boat.

Conventionally, in this type of bottom plate, an inverted H-shaped connecting rod is sandwiched between one end of the connecting surface of each plate that makes up the bottom plate, and another plate is fitted into the U-shaped groove to combine each plate to form the bottom fabric. It was laid on top.

In addition, in order to lay the bottom plate in the shape of a bottom cloth surrounded by an annular air cylinder without causing the bottom cloth to sag, the total length of the bottom plate in the front-rear direction must be made equal to the total length of the bottom cloth.

When the plates are lined up and the bottom plate is laid on the bottom fabric, the protrusion of the connecting rod protrudes, so it is necessary to forcefully push the plate to be assembled onto the bottom fabric.

Therefore, assembling this plate material is very troublesome.

Furthermore, there is a structure disclosed in Japanese Patent Publication No. 50-34317 in which a joint is attached in a protruding manner to the upper surface edge of the connecting end surface of each plate material, and the joints are fitted and connected. Since the joint is attached in a protruding manner on the top surface, there is a risk that the user may be injured by running over the joint, and since the joint is fitted on a curved surface, the fitting condition is weak.

Therefore, the present invention was devised to eliminate the inconveniences and defects of the conventional products mentioned above.The purpose of this invention is that it can be easily and easily installed by simply pushing it in, and at the same time it is safe and stable. The purpose is to provide an excellent and strong bottom plate for rubber boats.

Below, an embodiment of the present invention will be described based on the drawings.The bottom plate A consists of a large number of plate materials a+ a... arranged in the front-rear direction, and the right and left edges of the large number of plate materials a... are held together by the clamping rods b, and each plate material a...

(Figure 4).

Then, the groove 1b', which has a substantially V-shaped cross section, of the connector 1 is attached to each plate material a so that the inclination direction of the groove 1b' is directed forward and upward of the rubber boat.

Fit and secure it to the fitting protrusion a4 of a... with a screw or the like.

Therefore, the cross section of the opposite side, that is, the forward direction side of the rubber boat is approximately V.
The tapered convex portion a5 of another plate material a fits smoothly into the letter-shaped groove 1b' due to its inclined surface a5'.

In the figure, B' indicates the annular air cylinder of the rubber boat. Next, each plate material a

The tapered convex portion a5 is fitted into the groove 1b' having a substantially V-shaped cross section to form each plate material a.

A... are sequentially lined up and connected in the front-rear direction, and the last plate a (in the illustrated example, two plates combined in a V-shape) is made oblique and its tapered convex portion a5 is to be connected.
When the connecting device 1 is pushed downward in line with the groove 1b' having a substantially V-shaped cross section, the tapered convex portion a5 fits into the groove 1b' having a substantially V-shaped cross section, and the bottom plate having the same upper and lower surfaces is formed. A is formed on the bottom fabric B (FIG. 2).

Next, use the clamping rods to clamp and tighten each plate material ay a.
Prevent ... from disassembling.

Since the bottom plate A is formed in substantially the same shape as the bottom plate B of the rubber boat, it will not sag.

As described above, in the bottom plate of a rubber boat formed by arranging a large number of plate materials in the front direction, the present invention has a fitting convex portion on one side of the connecting end surfaces of the mutually connected plate materials, and a substantially ■-shaped tapered convex portion on the other side. The connection was made via a connecting tool that integrally has a groove with a U-shaped cross section that fits and secures to the fitting convex part, and a groove that has a roughly V-shaped cross section that engages and connects the tapered convex part. It has excellent effects such as:

(1) The connecting end surface of each plate is a connecting tool with a cross section of approximately V, in which a concave groove with a U-shaped cross section is fitted and fixed to a fitting convex portion provided on one end surface.
Since the character-shaped groove and the tapered convex part provided on the other end surface that engages with the groove are combined, the tapered convex part of the plate material to be installed last can be pushed downward to match the approximately V-shaped cross-sectional concave groove. Since it can be incorporated into the system, it is easy and convenient to incorporate it.

(2) Since a fitting convex portion and a tapered convex portion are formed on the connecting end surface, the connecting tool is fitted flush with the upper and lower surfaces of each member, making it easy for the user to slip or sleep. It is very safe as there is no risk of injury due to the connection, and at the same time, since it is connected by plane, it becomes a strong connection structure, and the plate material of the desired thickness can be used to form a strong bottom plate. It can also greatly improve safety.

Therefore, the intended purpose can be achieved.
