Description

本考案は、船本体の左右にフロートを配置する小型ボートに関する。 The present invention relates to a small boat in which floats are arranged on the left and right sides of a ship body.

前記小型ボートとしては、例えば特許文献１および２に示すものがある。これら特許文献１・２に記載の小型ボートは、自動車等に積み込めて運搬が容易であり、手軽に池や海等に出て釣り等を楽しめる。特に船本体の前後長が１．５ｍ未満のものは小型船舶検査が免除されるため、ユーザーの負担が少なく人気がある。そして、特許文献１・２に記載の小型ボートでは、船本体の左右にフロートをそれぞれ配置したことで、小型ボートの安定性が高まっている。 Examples of the small boat include those disclosed in Patent Documents 1 and 2. These small boats described in Patent Documents 1 and 2 are easy to carry by being loaded on an automobile or the like, and can easily go out to a pond or the sea to enjoy fishing and the like. In particular, those with a ship body length of less than 1.5m are popular because they are exempt from small vessel inspections and are less burdensome for users. And in the small boat of patent document 1 * 2, the stability of a small boat is increasing by having arrange | positioned the float to the left and right of a ship main body, respectively.

ところが、特許文献１に記載の小型ボートでは、該特許文献１の図１に示すように、船本体と左右のフロートとを左右方向に並べて配置してある。このため、小型ボートの左右方向の安定性は確保できるが、前後方向の安定性は依然として不十分であった。 However, in the small boat described in Patent Document 1, as shown in FIG. 1 of Patent Document 1, the ship body and the left and right floats are arranged side by side in the left-right direction. For this reason, although the stability of the small boat in the left-right direction can be ensured, the stability in the front-rear direction is still insufficient.

特許文献２に記載の小型ボートは、特許文献１に記載の小型ボートを改良したものであって、該特許文献２の図１に示すように、船本体の後側左右から船本体の後方へ向けて左右のフロートを突出状に配置してある。これにて、特許文献２の小型ボートでは、左右方向の安定性が確保されるうえ、小型ボートの前後方向の安定性も向上する。 The small boat described in Patent Document 2 is an improvement of the small boat described in Patent Document 1, and as shown in FIG. 1 of Patent Document 2, from the rear left and right of the ship body to the rear of the ship body. The left and right floats are arranged in a protruding manner. Thereby, in the small boat of patent document 2, stability in the left-right direction is secured, and stability in the front-rear direction of the small boat is also improved.

特開２０００−５３０７３号公報（図１）Japanese Unexamined Patent Publication No. 2000-53073 (FIG. 1) 登録実用新案第３０９７０８０号公報（図１・図７−８）Registered Utility Model No. 3097080 (FIGS. 1 and 7-8)

特許文献２の小型ボートでは、該特許文献２の図１に示すように、前後一対の横向き連結棒の両端に左右のフロートがそれぞれ連結され、両横向き連結棒間に左右一対の縦向き連結棒が掛け渡されている。かかる縦向き連結棒は、特許文献２の図４に示すように、補強部材を介して船本体の後壁に貫通状態で支持されている。 In the small boat of Patent Document 2, as shown in FIG. 1 of Patent Document 2, left and right floats are respectively connected to both ends of a pair of front and rear horizontal connecting rods, and a pair of left and right vertical connecting rods are connected between the both horizontal connecting rods. Is over. As shown in FIG. 4 of Patent Document 2, such a vertically-oriented connecting rod is supported in a penetrating state on the rear wall of the ship body via a reinforcing member.

該補強部材は、縦向き連結棒が挿通する筒体と、該筒体の一端に一体形成した鍔と、筒体の他端側に係合した抑え板と、防水用のパッキンとからなっており、これら部材が船本体にそれぞれ取り付けられている。つまり、特許文献２の小型ボートでは、補強部材を船本体に取り付けるための手間が掛かることになる。 The reinforcing member includes a cylindrical body through which the longitudinal connecting rod is inserted, a flange integrally formed at one end of the cylindrical body, a holding plate engaged with the other end of the cylindrical body, and a waterproof packing. These members are respectively attached to the ship body. That is, in the small boat of patent document 2, the effort for attaching a reinforcement member to a ship main body will be taken.

一方、特許文献２の図８に示す別実施例の小型ボートでは、左右の縦向き連結棒の中間部を上側に湾曲させて船本体の後壁を跨がせ、船本体の後壁の通孔に取り付けた支持具によって、左右の縦向き連結棒の中間部を船本体の後壁にそれぞれ支持している。これによると、特許文献２の図９に示すように、支持具を船本体の後壁の通孔に挿通させるだけで該支持具を通孔に取り付けることができ、前記補強部材よりも船本体に取り付けるための手間が軽減される。 On the other hand, in the small boat of another embodiment shown in FIG. 8 of Patent Document 2, the middle part of the left and right vertical connecting rods is curved upward so as to straddle the rear wall of the ship body, and the rear wall of the ship body is passed through. The intermediate parts of the left and right vertical connecting rods are supported on the rear wall of the ship body by the support members attached to the holes. According to this, as shown in FIG. 9 of Patent Document 2, it is possible to attach the support tool to the through hole only by inserting the support tool through the through hole of the rear wall of the ship main body. The time and effort for attaching to the machine is reduced.

ところが、縦向き連結棒を湾曲状に加工することは容易ではなく、この加工の分だけコストと手間とがかかってしまう。また、縦向き連結棒が円柱形状であるために、船本体の後壁の上面に対して線接触する（特許文献２の図９参照）。このため、該接触箇所に力が集中し、船本体の後壁の上面の早期の磨耗等を招くことになる。 However, it is not easy to process the vertical connecting rod into a curved shape, and costs and labor are required for this processing. Further, since the vertical connecting rod has a cylindrical shape, it makes line contact with the upper surface of the rear wall of the ship body (see FIG. 9 of Patent Document 2). For this reason, force concentrates on the contact location, leading to early wear on the upper surface of the rear wall of the ship body.

本考案の目的は、左右方向および前後方向の安定性を高めるための手間を低減でき、しかも船本体の早期の磨耗等を招き難い小型ボートを得ることにある。 An object of the present invention is to obtain a small boat that can reduce the effort for increasing the stability in the left-right direction and the front-rear direction, and that does not easily cause early wear of the ship body.

これにて、本考案の小型ボートは、船本体１、左右のフロート２・２、連結棒４・５・６・７および載置板４０等に分解される。次いで、左右のフロート２・２を船本体１の船内１３に収容し、その左右のフロート２・２の上に連結棒４・５・６・７および載置板４０等を積んで、例えば自動車に搭載する。 Thus, the small boat of the present invention is disassembled into the ship body 1, the left and right floats 2 and 2, the connecting rods 4, 5, 6, and 7, the mounting plate 40, and the like. Next, the left and right floats 2 and 2 are accommodated in the ship 13 of the ship body 1, and the connecting rods 4, 5, 6, and 7 and the mounting plate 40 are stacked on the left and right floats 2 and 2, for example, an automobile. To be installed.

本考案の小型ボートを組み立てるには、前側の横向き連結棒４を船本体１の後側の左右の横向き貫通孔１５・１５に通したのち、両横向き連結棒４・５の両端を、左右のフロート２・２の左右の接続部１９・１９の挿通孔２１にそれぞれ挿通させる。これにより、横向き連結棒４・５の係合凸部２５が接続部１９の係合孔２２に係合して、両横向き連結棒４・５の両端に左右のフロート２・２がそれぞれ連結される。 In order to assemble the small boat of the present invention, the front side connecting rod 4 is passed through the left and right side through holes 15 and 15 on the rear side of the ship body 1, and then both ends of both side connecting rods 4 and 5 are connected to the left and right sides.

As a result, the engaging projections 25 of the horizontal connecting rods 4 and 5 engage with the engaging holes 22 of the connecting portion 19, and the left and right floats 2 and 2 are respectively connected to both ends of both the horizontal connecting rods 4 and 5. The

次に、各係止機構３４の係止材３５を船本体１の後壁９の各通孔３７にそれぞれ通し、各係止材３５の前後の折曲部３５ａを、左右の縦向き連結棒６・７の挿通孔３８にそれぞれ貫通するとともに載置板４０を貫通させる。この状態で、各係止材３５の前後の屈曲部３５ａのネジ部にグリップナット３６をそれぞれ締め込む。また、各連結機構２７の前後の把持材３２・３２の下部間に前後の横向き連結棒４・５を挟み込んで、アイナット３１をボルト３０に締め込む。次いで、両縦向き連結棒６・７の前後両端および載置板４０にボルト４２をそれぞれ貫通させて、該ボルト４２にアイナット４３を締め込む。これにて、図１の状態に組み上げられる。 Next, the locking members 35 of the locking mechanisms 34 are respectively passed through the through holes 37 of the rear wall 9 of the ship body 1, and the front and rear bent portions 35a of the locking members 35 are connected to the left and right vertical connecting rods. 6 and 7 are inserted through the insertion holes 38 and the mounting plate 40 is penetrated. In this state, the grip nuts 36 are fastened to the screw portions of the bent portions 35a before and after each locking member 35, respectively. Further, the front and rear connecting rods 4 and 5 are sandwiched between the lower portions of the front and rear gripping members 32 and 32 of each connecting mechanism 27, and the eye nut 31 is fastened to the bolt 30. Next, the bolts 42 are respectively passed through the longitudinal front and rear ends of the connecting rods 6 and 7 and the mounting plate 40, and the eye nut 43 is tightened into the bolts 42. Thus, the state shown in FIG. 1 is assembled.

このように、左右のフロート２・２が、船本体１の後側左右から船本体後方へ向けて突出状に配置されて、連結棒４・５・６・７によって船本体１にしっかりと取り付けられているので、船本体１の前後長が短くても、左右のフロート２・２によって左右方向および前後方向の安定性が確保される。 In this way, the left and right floats 2 and 2 are arranged so as to protrude from the rear left and right of the ship body 1 toward the rear of the ship body, and are firmly attached to the ship body 1 by the connecting rods 4, 5, 6, and 7. Therefore, even when the front and rear length of the ship body 1 is short, the left and right floats 2 and 2 ensure stability in the left and right direction and the front and rear direction.

連結棒４・５・６・７は、それぞれ直線状に形成されているので、例えば連結棒４・５・６・７を湾曲させる場合よりも、連結棒４・５・６・７の加工に要する手間が軽減される。また、各縦向き連結棒６・７が、図４および図５に示すように、船本体１の後壁９の上面９ａにそれぞれ面接触するので、例えば縦向き連結棒６・７が円柱状であって船本体１の後壁９の上面９ａに線接触するものに比べて、接触箇所に力が集中することが抑えられる。これにて、各縦向き連結棒６・７と船本体１の後壁９の上面９ａとの擦れ合い等による船本体１の後壁９の上面９ａの磨耗等を抑えることができる。 Since the connecting rods 4, 5, 6, 7 are each formed in a straight line, for example, the connecting rods 4, 5, 6, 7 are processed more than when the connecting rods 4, 5, 6, 7 are curved. The time and effort required is reduced. Further, as shown in FIGS. 4 and 5, the vertical connecting rods 6, 7 are in surface contact with the upper surface 9 a of the rear wall 9 of the ship body 1, for example, the vertical connecting rods 6, 7 are cylindrical. And compared with what makes line contact with the upper surface 9a of the rear wall 9 of the ship main body 1, it can suppress that force concentrates on a contact location. As a result, it is possible to suppress wear and the like of the upper surface 9a of the rear wall 9 of the ship body 1 due to friction between the longitudinal connecting rods 6 and 7 and the upper surface 9a of the rear wall 9 of the ship body 1.

船本体１の後壁９の各通孔３７は、前述のように他の船本体１の連結用のベルトを通すために形成されたものであって、この各通孔３７の大きさで強度や防水性等が得られるように設計および防水性能の試験等がされている。かかる通孔３７の上下左右の大きさは、縦向き連結棒６・７の上下左右の大きさに比べてあまり大きくない。本考案では、該通孔３７に、縦向き連結棒６・７よりも上下左右の大きさが小さい係止機構３４の係止材３５が挿通するので（図５参照）、縦向き連結棒６・７を挿通させるために、通孔３５を大きくしたり通孔３５とは別に孔を設けたりしなくても済む。 As described above, each through hole 37 in the rear wall 9 of the ship body 1 is formed to pass a belt for connecting another ship body 1, and the size of each through hole 37 is high in strength. In addition, design and waterproof performance tests have been conducted so as to obtain water resistance and the like. The vertical and horizontal sizes of the through-hole 37 are not so large as compared to the vertical and horizontal sizes of the vertical connecting rods 6 and 7. In the present invention, since the locking member 35 of the locking mechanism 34 having smaller vertical and horizontal dimensions than the vertical connecting rods 6 and 7 is inserted into the through holes 37 (see FIG. 5), the vertical connecting rod 6 In order to insert 7, it is not necessary to enlarge the through hole 35 or provide a hole separately from the through hole 35.

なお、前後の横向き連結棒４・５は、長さ寸法が大きい方が左右のフロート２・２の間隔が大きくなって、小型ボートの左右方向の安定性が高まるが、横向き連結棒４・５の長さ寸法を大きくし過ぎると、本考案の小型ボートを分解して運搬する際に横向き連結棒４・５が嵩張ってしまうことになる。したがって、横向き連結棒４・５の長さ寸法は、これら小型ボートの左右方向の安定性と運搬性とを考慮して決定される。 It should be noted that the front and rear horizontal connecting rods 4 and 5 have a larger length, and the distance between the left and right floats 2 and 2 becomes larger, and the lateral stability of the small boat is improved. When the length dimension of is too large, the horizontal connecting rods 4 and 5 become bulky when the small boat of the present invention is disassembled and transported. Therefore, the length dimension of the horizontal connecting rods 4 and 5 is determined in consideration of the lateral stability and transportability of these small boats.
