Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to pneumatic boats such as water boats and snow boats.

(Prior art) Conventionally, in this type of pneumatic boat, the gunwale of the boat body is formed with an air bladder, a seat is stretched halfway up the inner peripheral surface of the gunwale, and a handle is provided on the upper surface of the gunwale. A snow/water boat is known which is provided with sliding strips on both left and right sides of the underside of the gunwale, the edges of which are made of a hard material such as synthetic resin or metal and covered with covering strips. (Refer to Utility Model Publication No. 54-8558).

(The problem that the invention aims to solve) However, since the pneumatic boat of this structure has the shape of a boat and is a type of boat that the rider rides inside, the rider can move his or her body back and forth according to the curves and boards while riding on it. The mobility of the rider's body, such as moving left and right or twisting, and the maneuverability of the boat when cornering, etc. are not necessarily good, and the sense of speed and maneuverability are inferior, and when the rider rides, There are defects such as poor stability and easy fatigue due to the forward stretching posture, and the bottom of this structure is a single-layer structure like the other parts, and the bottom is made of hard material. Because it has edges, it tends to be easily torn due to collision with other objects or rubbing. For example, if the bottom is rubbed hard against a rocky surface on a reef while driving on water, the same part can easily be rubbed off. There were problems such as air leakage.

The object of the present invention is to provide a new pneumatic boat that solves the serious problems.

(Means for Solving the Problems) In order to solve the above problems, the present invention has a rocket shape constructed by welding the entire periphery of the upper surface plate 1 and the lower surface plate 2 made of a thermoplastic soft synthetic resin sheet. A large-diameter central hollow body 3 and left and right hollow bodies 4 exhibiting
A supply/exhaust plug 5, 6, 6' is attached to each of the hollow bodies 3, 4, 4' to allow expansion and contraction, and left and right hollow bodies 4, 4' are provided on both sides of the central hollow body 3. A pair of hook members 9 are fixed side by side to form the boat body 7, and are integrally molded with thermoplastic soft synthetic resin on both left and right sides of the upper surface of the front part of the central hollow body 3.
9' is attached, and a mooring ring 10 is integrally provided on the upper surface of these claw members 9, 9', and both mooring rings 1 are attached.
0 to both ends of the reins 11, and a large number of protrusions 1 parallel to the surface are connected to almost the entire lower surface of the central hollow body 3 and the left and right hollow bodies 4, 4'.
2 is provided with a sliding plate 13 made of a soft synthetic resin material.
is pasted with the protrusion 12 facing in the front-rear direction.

(Example) The example shown in the figure is a large-diameter central hollow body 3 and left and right hollow bodies that are formed into a rocket shape by welding the entire periphery of an upper plate 1 made of a thermoplastic soft synthetic resin sheet and a lower plate 2 made of the same. The central hollow body 3 and the left and right hollow bodies 4, 4' are connected to supply and exhaust plugs 5, 6,
6' to make it expandable and contractible, and the left and right hollow bodies 4, 4' are lined up and fixed on both sides of the central hollow body 3 to form the boat body 7, and the upper surface of the middle part of the central hollow body 3 is made of thermoplastic soft material. A seat plate 8 made of a synthetic resin sheet is laid down, and a pair of lever members 9, 9' integrally molded from thermoplastic soft synthetic resin are attached to the left and right sides of the upper surface of the front part. A mooring ring 10 is integrally provided on the upper surface, and both ends of the reins 11 are connected to both mooring rings 10, and a mooring ring 10 is provided on the surface almost over the entire lower surface of the central hollow body 3 and the left and right hollow bodies 4, 4'. A sliding plate 13 made of a soft synthetic resin material and provided with a large number of parallel protrusions 12 is pasted with the protrusions 12 facing in the front-rear direction.

(Operations and effects of the invention) The pneumatic boat according to the invention is used on water, snow, etc. by a rider straddling the central hollow body 3 and placing both feet on the left and right hollow bodies 4, 4'. However, a sliding plate 13 made of a soft synthetic resin material is provided with a large number of protrusions 12 parallel to the surface on almost the entire lower surface of the central hollow body 3 and the left and right hollow bodies 4, 4'. Since the protrusions 12 are pasted so that they face forward and backward, the protrusions 12 reliably prevent the boat from sliding sideways.This not only provides good directionality when the boat is going straight, but also helps the rider avoid curves while traveling. It is highly responsive when changing the direction of the boat by twisting, leaning, or pulling on one side of the reins at turning points, which allows for agile movements. In addition, in the present invention, such a sliding plate 13 is attached to the lower surface of the central hollow body 3 and the left and right hollow bodies 4, 4' as described above, so that each of these hollow bodies can be The bottom portions of 3, 4, and 4' are significantly reinforced, and even if these portions collide with other objects or are subjected to strong friction while driving, there is a risk that they will easily tear or cause air leaks, as in the above-mentioned known products. Therefore, the present invention has the effect of being able to sufficiently solve the above-mentioned problems.
