BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foldable air boat bottom plate.

[0002]

2. Description of the Related Art Conventionally, a bottom plate of an air boat (rubber boat) is composed of a plurality of plate pieces and a connecting rod, one side of the connecting rod is fixed to the plate piece, and the other side is engageable with the plate piece. And the connecting rods are interposed between the respective plate pieces so that the plate pieces can be jointed and used (Jitsuko Sho 58-983).
No. 3), a plurality of plate pieces and a male and female lateral edge frame for joining the plate pieces, and a female lateral edge frame and a male lateral edge frame that can be fitted to each other at the ends of the plate pieces. Which are fixed to each other so that they can be used as a single bottom plate by fitting both lateral edge frames of the plate piece together (Actual Development Sho 6
No. 0-95389), and a plurality of plate pieces are connected by a flexible connecting sheet so that they can be folded at the connecting sheet (Japanese Utility Model Publication No. 61-53291).

[0003]

However, since the bottom plate of (1) is not connected with the plate pieces (including the one to which the connecting rod is fixed) constituting the bottom plate, it is easy to separate the bottom plate from each other.
Inconvenient to handle during assembly and storage. The bottom plate also has the same inconvenience as the above because the plate pieces to which the female lateral edge frame and the male lateral edge frame are fixed are not connected. Also, the bottom plate has the above-mentioned drawbacks because the plate pieces are connected in series by a connecting sheet, but when laid on the bottom of the boat,
When an object is placed on the bottom plate, the bottom plate is easily bent at the connecting sheet portion, so that there is a drawback in that it lacks stability.
Further, since the plate pieces are fixed to the connecting sheet, there is a drawback that when it is necessary to remove a part of the plate pieces or the connecting sheet, they cannot be removed and parts cannot be replaced.

The present invention has been made in view of the above points,
An air boat that eliminates the above-mentioned conventional drawbacks, can be folded, and is easy to handle when assembling and storing without having the constituent members separate from each other except when necessary and capable of removing the constituent members when necessary. The purpose is to provide a bottom plate.

[0005]

That is, according to the present invention, (1) a plurality of bottom plate pieces are provided so as to straddle each of the bottom plate pieces, and a flexible connecting member is provided to connect the plurality of bottom plate pieces in series. A bottom plate of an air boat connected to each other, the bottom plate pieces being adjacent to each other in the direction along the connecting member of the bottom plate , which can be fitted to each other , and when fitted together.
And connecting members that avoid bending at the connecting portion is attached respectively, the cooperative member is mounted removably to the mounting portion of the bottom plate piece of the connecting member or phases adjacent connecting member adjacent phase The bottom plate of the air boat according to (1), wherein the bottom plate of the air boat and (2) the connecting member have a bending tendency or a slacking tendency in a direction opposite to the direction of the bottom plate. Use as a summary.

Embodiments of the present invention will now be described in detail with reference to the drawings. 1 and 2 are views showing an example of the bottom plate of the air boat of the present invention, FIG. 1 is a schematic view of the bottom plate of the air boat, and FIG. 2 is an enlarged vertical cross-sectional view taken along line AA of the main part of FIG. Is. As shown in FIG. 1, the bottom plate 1 of the air boat of the present invention is provided with a flexible connecting member 3 extending between the plurality of bottom plate pieces 2 (21, 22, 23, 24). ,
The bottom plate pieces 2 are connected in series by the connecting member 3.

In this embodiment, as shown in FIG.
The connecting member 3 has a connecting member 4 (41, 4
2) are installed respectively. Adjacent bottom plate pieces 21 and 22 are attached to the connecting members 41 and 42, respectively, and the bottom plate pieces 21 and 22 are indirectly connected by the connecting member 3 via the connecting members 41 and 42, respectively. Has been done. In the figure, 5 is an air boat body, 6 is a grip portion, 7 is a transom plate provided at the rear of the boat, 8 is a stopper for fixing the bottom plate piece 2 on the tip side to the boat tip portion, and d is a connecting portion. Respectively.

As one mode of mounting the connecting member 3 to the connecting members 41 and 42, for example, as shown in FIG. 2, the engaging portions a1 and a having openings in a part of the connecting members 41 and 42 are provided.
2 is provided, and at both ends of the connecting member 3, the ball pools 31 and 3 are provided.
2 is provided, and the balls 31 and 32 are connected to the locking portion a.
The connecting members 41 and 42 are connected by being inserted into 1 and a2 and locked. The sizes and shapes of the openings of the ball pools 31 and 32 and the locking portions a1 and a2 are such that the ball pools 31 and 32 can be inserted into the locking portions a1 and a2 and can be removed from the locking portions as necessary. Have been considered to. The locking portions may be provided at the position corresponding to the upper surface of the bottom plate 1, the position corresponding to the lower surface, or both the upper and lower surfaces, as long as they are at the positions facing the positions of the locking portions of the adjacent connecting members. However, it is preferable to provide it on the lower surface of the bottom plate 1 because the surface of the bottom plate 1 becomes smoother so that a person does not feel uncomfortable when riding on the bottom plate 1. If the connecting member is made of a material having a soft surface, even if the bottom plate is laid on the boat body with the engaging portion of the connecting member facing the upper surface, the engaging portion has a soft surface. Since it is covered by the connecting member, the tactile sensation is not significantly deteriorated.

The connecting members 41 and 42 are provided with bottom plate piece holding portions b1 and b2 having a substantially U-shaped cross section on one end face thereof, and the bottom plate piece holding portions b1 and b2 are bottom plate pieces. The contact surface is formed with irregularities having a saw-toothed cross-section so that the bottom plate pieces 21 and 22 can be reliably held by the bottom plate piece holding portions b1 and b2, and the bottom plate piece 2 can be held if necessary.
1, 22 are configured so that they can be freely attached and detached.

Further, on the end faces of the connecting members 41, 42 opposite to the bottom plate piece holding portions b1, b2, there are provided a contact portion c1 provided with a concave ridge and a contact portion c2 provided with a convex ridge, respectively. The contact portions c1 and c2 can be fitted to each other, and when the contact portions c1 and c2 are fitted to each other, the contact portions d of the connecting members 41 and 42 can be bent. Absent. The form of the abutting portions c1 and c2 is not limited to the above-described one, and the abutting portions c1 and c2 can be fitted to each other, and the bottom plate 1 is not bent at the connecting portion d when the both are fitted. Any form is acceptable.

As shown in FIG. 2, the connecting member 3 is capable of folding the bottom plate 1 by disengaging at least the connecting members 41 and 42 and bending at the connecting member 3. is necessary. When the connecting member 3 is made of a non-stretchable material and is folded in the direction of the arrow e in the drawing, the length of the connecting member 3 should be slightly shorter than L in the drawing or longer than that. It may be adjusted so that the above conditions are satisfied, and when folding in the opposite direction, the length may be adjusted accordingly. In the present invention, the connecting member 3 preferably has elasticity. When a material that can be expanded and contracted is used as the connecting member 3, the length of the connecting member 3 is not limited to L and may be shorter than L or may be longer than that.

In the present invention, as another example of mounting the connecting member 3 to the connecting members 41 and 42, as shown in FIG. 3, the connecting member 3 has its end portions connected to the connecting member 4 respectively.
It may be provided so as to be sandwiched between the first and second plates 42 and the bottom plate pieces 21 and 22. In such a case, the connecting member does not need a locking portion. As long as the position where the end of the connecting member 3 is sandwiched is a position that does not interfere with the fitting of the connecting members 41 and 42, the position corresponding to the upper surface of the bottom plate 1 also corresponds to the lower surface, as described above. It may be provided at the position or on both the upper and lower surfaces. Incidentally, the connecting member 3 and the connecting member 4
In the case where 1 and 42 are connected as described above, even if the surface of the bottom plate on the side where the connecting member is provided is the front side (upper side) is laid on a boat, a person feels unevenness. Since it does not give a sense of discomfort, there is no need to worry about the front and back direction when laying. Further, if the connecting member is made of a material having a soft surface, the tactile sensation is not significantly reduced even if the connecting member is on the front side of the bottom plate.

In the present invention, the connecting member 3 and the connecting member 4 may be provided over the entire width of the bottom plate piece 2 as shown in FIG. Good. Further, when it is provided at a part, as shown in FIG. 4, one pair (the same figure (a)) per one connecting part (for example, the connecting part of the arrow d in the figure) or a plurality of pairs (the same figure (b)). But it's okay.

In the present invention, a flexible member is used as the connecting member, for example, PVC sheet or PV.
A synthetic resin sheet such as C tarpaulin, a woven cloth, a rubberized cloth, or a rubber sheet can be used.

As the bottom plate piece and the connecting member, any material can be used as long as it is not easily deformed. For example, various metal materials such as aluminum or its alloys, various woods, various plastics can be used. Although rubber, etc. can be used, a comparatively lightweight one is preferable.

In the present invention, the connecting member is moved in the direction opposite to the direction of the bottom plate so that the middle part of the connecting member is easily bent or loosened in the direction opposite to the direction of the bottom plate. It is preferable that a bending habit or a sag habit is provided. When the connecting member is configured in this manner, when the folded bottom plate is extended and assembled, the connecting members are connected between the adjacent connecting members provided between the bottom plate pieces. There is no risk of the members being pinched, and the assembly work can be performed smoothly.

The above-mentioned bending habit or slacking habit of the connecting member can be imparted by the following means, for example. That is, as shown in FIG. 6, if any one portion of the connecting member 3 is bent in a direction opposite to the direction of the bottom plate to form a removal-like portion 33, the extraction-like portion 33 is formed. Sama part 3
In the extraction base f of No. 3, a force for pushing the extraction-like portion 33 in the direction of the arrow g opposite to the direction of the bottom plate is always exerted in order to return the bent connecting member 3 to the original state. The appearance portion 33 is not likely to be sandwiched between the connecting members 41 and 42 provided at both ends of the connecting member 3. This effect is more prominent when the length of the connecting member 3 is significantly longer than the length L defined by the length between the connecting members 41 and 42 in FIG. is there.

As shown in FIG. 7, for example, as shown in FIG. 7, the extraction-like portion 33 extracts the substantially central portion of the connecting member 3 in a direction opposite to the direction of the bottom plate, and provides a crease 9 at the tip thereof (FIG. 7).
(A)) The substantially central portion of the connecting member 3 is extracted in a direction opposite to the direction of the bottom plate, and the vicinity of the base portion f is sewn by sewing means such as sewing using a sewing machine (10 in the figure is a sewing machine). 7 (b), a substantially central portion of the connecting member 3 is extracted in a direction opposite to the direction of the bottom plate, and a laminated portion of the connecting member 3 in the extracted portion. An adhesive 11 may be provided between the layers to laminate and bond the connecting member 3 bent at the extraction site (FIG. 7C). In addition, the extraction-like portion 33 may be configured by using any of the above two to three means.

When the above-mentioned means is adopted, the connecting member 3 is made of a member such as an unvulcanized rubber pulling cloth, a rubber sheet or the like which is easily bent. Further, even in the case of adopting the means of (1), it is more preferable to use a member having a crease easily as the connecting member 3, but it is not particularly limited thereto. When the other means is adopted, a member such as rubber or PVC that can be adhered by an adhesive is used. As the adhesive, a conventionally known adhesive such as an adhesive for rubber or an adhesive for soft vinyl can be used.

Next, the case of using the bottom plate 1 of the air boat of the present invention will be described with reference to FIG. To fold the bottom plate of the air boat 1 of the present invention in the same state as when it was laid on the bottom of the air boat, first use the handle hole 6 at each connecting portion d of the bottom plate pieces 2 to each bottom plate piece. Two
Are sequentially shifted in the order of 21 to 24 in the anteroposterior direction of the bottom plate 1 to separate the connecting members 41 and 42 from each other, and the connecting members 41 and 4 are connected.
The fitting with 2 is removed, and the state shown in FIG. 1 is obtained. Next, the bottom plate 1 is bent at the connecting member 3, and the connecting member 41, 42 or the bottom plate piece 2 to which either one of them is attached at the end is folded into a shape as shown in FIG. 5, for example. .
In the present invention, the transom plate 7 attached to the rear part of the air boat may be connected to the bottom plate 1,
In that case, as shown in the drawing, the transom plate 7 and the bottom plate 1 may be folded at the connecting portion f and folded together with the bottom plate. The folding direction of the bottom plate 1 can be arbitrarily selected according to the number and size of the bottom plate pieces.

In order to lay the bottom plate 1 of the air boat of the present invention on the bottom of the air boat, the procedure reverse to the above may be carried out. The bottom plate pieces 24 to 21 are laid one by one toward the rear of the air boat. The bottom plate 1 is in one rigid state. In this state, the tip portion of the bottom plate piece 21 is at the position shown by the chain double-dashed line in FIG. Finally, the bottom plate piece 21 is fixed to the boat main body or an air keel (not shown) provided on the boat main body by using a stopper 8 (mount stopper, etc.) provided at the front part of the air boat.
To prevent the boat from moving in front of the boat. However, since the front portion of the boat is gradually narrowed toward the front, the bottom plate piece 21 hardly moves forward of the boat even if the stopper 8 is not necessarily provided. In addition, the handle hole 6 is the bottom plate piece 2
It may be provided at any part of the.

As described above, in the bottom plate of the air boat of the present invention, a flexible connecting member is provided by straddling a plurality of bottom plate pieces between the bottom plate pieces. It is a bottom plate of an air boat connected in series by
In the adjacent parts of the bottom plate pieces adjacent to each other in the direction along the connecting member of the bottom plate, connecting members that can be fitted to each other are respectively mounted, and the connecting member is a connecting member or Since the connecting member is detachably attached to the mounting portion of the bottom plate piece, if the bottom plate pieces are combined and the connecting member is fitted, a single rigid bottom plate is formed. It is possible to fold it compactly by separating the members for use at the portion of the connecting member, and to fold it together with the air boat so that it can be stored more compactly.
Moreover, in the bottom plate of the air boat of the present invention, since the bottom plate pieces are connected by the connecting member, they do not become inadvertently separated, and therefore, there is an effect that the labor for assembling and storing can be reduced. In addition, since the connecting member is detachably attached to the connecting member or the mounting portion of the connecting member to the bottom plate piece, the connecting member, the bottom plate piece, and the connecting member of any place may be selected as necessary. There is an advantage that any one or two or more parts can be removed, and for example, some parts can be replaced.

Further, in the above-mentioned bottom plate of the air boat, when the connecting member has a bending tendency or a slacking tendency in a direction opposite to the direction of the bottom plate, the folded bottom plate is extended and assembled. At this time, between adjacent bottom plate pieces, there is no possibility that the connecting member is sandwiched between the connecting members provided on each bottom plate piece, and the assembly work can be performed smoothly.
