【考案の詳細な説明】
この考案は、擬似樹木、特に、海中に投下する擬
似樹木に関するものである。[Detailed description of the invention] This invention relates to a pseudo tree, particularly a pseudo tree that is dropped into the sea.
海中における栽培漁業のために、集魚を目的と
して海中に人工魚礁や擬似樹木を投下することは
一般に行われている。 For cultivation and fishing in the sea, it is common practice to drop artificial reefs and artificial trees into the sea for the purpose of attracting fish.
従来、擬似樹木は第１図に示されるように、合
成樹脂製の幹１ａと複数本の枝１ｂとからなる樹
木本体１と、樹木本体１の下端に固定されるコン
クリートまたは鋼製の基台２とからなる。 Conventionally, as shown in FIG. 1, a pseudo tree consists of a tree body 1 consisting of a trunk 1a made of synthetic resin and a plurality of branches 1b, and a concrete or steel base fixed to the lower end of the tree body 1. It consists of 2.

ように投下するのに手間がかかる。 However, the pseudo tree has the following problems. That is, when the pseudo trees are transported by ship or vehicle, the transport efficiency is very poor because they cannot be stacked on top of each other. Further, it is necessary to drop the tree so that the tree body 1 lands upright on the seabed, but it takes time and effort to drop the tree in this way.

Furthermore, the present invention provides a pseudo-tree whose tree body always stands upright after being dropped, and which has a highly elastic tree body consisting of a buoyant trunk and a plurality of branches attached to the trunk; An upper groove is formed on the upper surface, a lower groove is formed on the lower surface in parallel with the upper groove, and a mounting shaft for rotatably attaching the lower end of the stem is fixed to the upper groove. It is characterized by becoming.

る。 As shown in FIGS. 2 to 4, the tree body 1 consisting of a trunk 1a and a plurality of branches 1b is made of a highly elastic material such as synthetic resin or rubber.
After being dropped into the sea, the inside of the trunk 1a is buoyant.
It is hollow so that it stands upright. In order to give greater buoyancy to the trunk 1a, a floating body may be attached to the top of the trunk 1a, or a synthetic resin or the like having high buoyancy may be enclosed within the trunk 1a. The base 2 attached to the lower end of the tree body 1 is made of concrete or steel, and has an upper groove 2a formed in the center of the upper surface, and a lower groove 2b wider than the upper groove 2a in the center of the lower surface. It is formed parallel to the upper groove 2a. A mounting shaft 3 for rotatably mounting the lower end of the trunk 1a is fixed horizontally to the center of the upper groove 2a.

として必らず第２図に示されるような状態に直立
する。 In order to drop the pseudo tree configured as described above into the sea, as shown in FIG.
A plurality of pseudo-tree bases 2 are placed in a line through the holder, and the pseudo-tree bases 2 are sequentially dropped into the sea starting from the first pseudo-tree. At this time, as shown in FIG. 6, the trunk 1a of the front tree body 1 is brought down backward, and the trunk 1a thus brought down is inserted into the lower groove 2b of the rear base 2. . Thereby, the pseudo trees can be continuously dropped into the sea without damaging the trunk 1a and branches 1b. Moreover, after being dropped into the sea, the trunk 1a always stands upright about the mounting shaft 3 due to buoyancy in the state shown in FIG. 2.
擬似樹木を格納および輸送する場合、幹１ｂを
倒せば基台２上に複数個の基台２を載置すること
ができるので格納および輸送効率がきわめて良
い。 When storing and transporting the pseudo-tree, a plurality of bases 2 can be placed on the base 2 by knocking down the trunk 1b, so the storage and transport efficiency is extremely high.
以上説明したように、この考案によれば、格納
および輸送効率が良く、海中への投下も容易に行
え、しかも、投下後は樹木本体が必らず直立する
といつた種々の有用な効果がもたらされる。 As explained above, this invention has various useful effects such as being efficient in storage and transportation, easy to drop into the sea, and that the tree itself always stands upright after being dropped. It will be done.
