Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a mounting structure for a seat plate in a rubber boat.

(Prior art) As shown in FIG. 6, the mounting structure of the seat plate installed between the air cylinders on both the left and right sides of a conventional rubber boat includes the upper surface portions of the air cylinders 1a and 1b on both the left and right sides, and the lower surface portions 3 at both ends of the seat plate 3.
Attach the velvet fastener to a, and
Some devices are attached and fixed by pasting a and 6b together.

(Problems to be Solved by the Invention) However, velvet fasteners have the property of being easy to peel in the peeling direction, but difficult to peel in the shearing direction. However, although the conventional mounting structure is difficult to peel off in the direction of displacement, it easily peels off when force is applied in the direction of peeling off the seat plate, and is particularly vulnerable to large instantaneous forces. Therefore, if you accidentally kick the seat board up while moving around the ship, it will easily come off, which is very inconvenient. However, the force applied when removing the seat board by hand is a static load, and the entire surface of the velvet fastener that is attached must be removed at the same time, making it extremely difficult to remove. It takes time and effort.

The present invention aims to solve the above-mentioned problems by taking advantage of the characteristics of the velvet fastener, and to provide a mounting structure for the seat plate that is easy to attach and detach.

(Means for Solving the Problems) The mounting structure of the seat plate in the rubber boat of the present invention which achieves the above-mentioned purpose is such that the seat plate is erected between the supporting parts attached to both the left and right air cylinders of the main body of the rubber boat. At the same time, the lower surfaces of both ends of the seat plate are supported by the supporting portions, and male or female bodies of a velvet type fastener are attached to the upper surface of both ends of the seat plate, and the upper surface of the fastener is bendable and fixed to the air cylinder. The gist of the present invention is that a locking piece with a corresponding fastener is fixed to cover the fastener from above.

(Example) An example of the present invention will be described based on the drawings.
In FIGS. 1 and 5, A is the rubber boat main body, and the left and right sides of the air cylinder 1, which is approximately elliptical in plan, are
Two front and rear seat plates 3 are installed between a and 1b, and a locking part 5 is provided at both ends of the seat plates 3 to both air cylinders 1a and 1b.
It is locked and fixed between both air cylinders 1a and 1b.

The locking part 5 is made by folding a piece of rubberized cloth approximately the same width as the seat plate 3 into two pieces, with the open side facing inward of the boat, and the lower side of the cloth being placed inside the upper surface of the left and right air cylinders 1a, 1b. It is formed by pasting it on both sides.

The lower surface of the bent inner surface of the locking portion 5 is used as a support portion 2 on which the lower surfaces of both ends of the seat plate 3 are placed and supported;
A female body 6b of a velvet fastener 6 is attached to the upper side of the same inner surface to form a locking piece 4 that bendably projects inward of the boat. Further, the lower surface portions of both ends of the seat plate 3 are formed into a tapered shape in accordance with the inclination angle of the support portion 2, and the male bodies 6a of the velvet type fasteners 6 are pasted on the upper surface portions of both ends. Both ends of the seat plate 3 are placed between the support parts 2 of the left and right air cylinders 1a and 1b, and locking pieces 4 are placed on the male body 6a on the upper surface of both ends from outside of both ends of the seat plate to cover the seat plate 3 side. The male body 6a and the female body 6b on the side of the locking piece 4 are attached, and the seat plate 3 is attached and fixed between the left and right air cylinders 1a and 1b.

Next, the operation of the above-described embodiment will be described. When an occupant sits on the seat plate 3, this load is supported by the support portions 2 of the left and right air cylinders 1a, 1b.
The rubberized fabric of the support portion 2 acts as a reinforcing material for the air cylinder 1 and protects the air cylinder 1. When force is applied to shift left and right, shearing force is applied to the velvet fasteners 6 at both ends of the seat plate 3, causing the left and right pneumatic cylinders 1a,
It is held up by the locking piece 4 that is fixed to 1b.
Also, when an impactful upward force is applied to the seat plate 3, such as by kicking up the seat plate 3, the locking pieces 4, which are fixed to cover both ends of the seat plate 3 from above, lock the base end. Since it is attached to the air cylinder 1, it is pulled relatively downward, and a shearing force is applied to the velvet fasteners 6 on the upper surface of both ends of the seat plate 3. The seat plate 3 is held by the resistance force of the velvet fastener 6 in the direction of shear force.

Furthermore, when removing the seat plate 3 from the air cylinder 1, if you pinch the tip of the locking piece 4 which can be bent freely and gradually peel off the attached velvet fastener 6 from the edge, it will peel off smoothly with extremely weak force. Therefore, the seat plate 3 can be easily removed.

Next, the embodiment shown in FIG. 3 will be described. Similar to the embodiment described above, the male body 6a and the female body 6b are disposed on the upper surface of both ends of the locking piece 4 and the seat plate 3, and the support part 2 and the A female body 6b and a male body 6a of a velvet fastener 6 are provided on the lower surface of both ends of the seat plate 3 facing the part 2, respectively.
is pasted, and both ends of the seat plate 3 are supported by supporting parts 2.
and a bendable locking piece 4, and the male body 6a and female body 6b are attached and fixed. Therefore, when the seat plate 3 is placed between the support parts 2, the seat plate 3 is fixed, making it easy to attach the locking piece 4, and velvet type fasteners are provided on both the upper and lower sides of both ends of the seat plate 3. Since it is fixed by attaching 6, it can be fixed more firmly than a method that attaches only the upper surface.

According to the above embodiment, when the seat plate 3 is removed, the locking piece 4 is bent with its fastener surface facing downward, so that the fastener surface is not exposed on the surface, so that the rubber boat There is no need to worry about damaging the fastener of the locking piece 4 while not spoiling the appearance of the locking piece 4.

The embodiment shown in FIG. 4 is mainly used when the seat plate 3 is installed at a relatively low position, and is made by bending a bendable rubberized cloth into a U-shape, and forming opposing surfaces on the inner surface. A female body 6b is attached to each of the ends, and a locking piece 4 is formed on the upper surface side and a support part 2 is formed on the lower surface side. Attach the bent side of this rubberized cloth to the air cylinder 1,
A reinforcing cloth 7 is pasted on both sides of the joint, and the locking piece 4 is
At the same time, the support portion is bent and extended inward of the boat. On the other hand, a male body 6a is attached to the upper and lower surfaces of both ends of the seat plate 3, and the female body 6b of the support part 2 is attached and supported on the lower surface of the male body 6a, and the female body 6b of the locking piece 4 is attached to the upper surface of the male body 6a. are attached, and both ends of the seat plate 3 are held between both members.

When an occupant sits on the seat plate 3 of the above embodiment and a downward load is applied, the rubberized cloth of the support part 2 is pulled.
A shearing force is applied to the velvet fastener 6 on the support portion 2 side, and the seat plate 3 is supported by the resistance force of the velvet fastener 6 in the shearing direction.
Further, when a force is applied to lift the seat plate 3 upward, the locking piece 4 and the velvet type fastener 6 on one side of the locking member function in exactly the same manner as in the embodiment described above.

If the locking piece 4 and the support surface 2 are made to extend long in the front-rear direction as shown in FIG. 5, the front-rear mounting position of the seat plate 3 can be adjusted steplessly.

(Effects of the invention) As described above, the present invention is fixed to the velvet fasteners at both ends of the bendable locking single seat plate so as to cover them from above. If you try to do so, even if a load force is applied, the force acts in a direction that causes the velvet fastener on the top side of the seat plate to peel off in the shearing direction, making it difficult for the fastener to peel off. Even if you raise it up, it will not come off.

Further, when removing the seat plate, the velvet fastener of the locking piece can be gradually peeled off from the end, making it easy to peel off, and therefore, the seat plate can be easily removed.
