させるための、膨張式救命筏用安定水嚢に係るも
のである。[Detailed description of the invention] Industrial application field This invention is an inflatable life raft that can be stably positioned on the water surface to reduce rocking and prevent flipping. This relates to a stable water bladder for use.
従来の技術
従来より膨脹式救命筏を、揺動を少なくし、反
転等を生じる事の無いよう、水面に安定的に位置

成する方法は知られている。Conventional Technology There is a conventional method of forming a stable water bladder at the bottom of an inflatable life raft in order to stably position the inflatable life raft on the water surface to reduce rocking and prevent it from turning over. Are known.

ない欠点を有していた。 However, the conventional stable water bladder is
Like the invention described in Publication No. 13664, this is simply a bag-like material provided with a seawater inlet and fixed to the lower surface of the bottom fabric. Therefore, if enough seawater flows into the stable water bladder, the life raft will have a stable function, but it takes a long time for the seawater to flow into the stable water bladder sufficiently. During this time, there is a high possibility that the life raft will swing violently or turn around. In addition, until seawater flows into the stable water bladder, the center of gravity is high, so
Life rafts thrown into the sea from a ship often tip over and inflate in an inverted state before a person in distress can get on board, and it takes a lot of trouble and danger to return them to an upright position on the sea surface. It has disadvantages that are not desirable in emergency situations.

気溜まりの発生を助長させるものとなる。 There is also an invention in which the body of the water bladder is formed into a continuous annular shape, such as the invention described in Japanese Patent Publication No. 56-10237. However, in this invention, since the water bladder body is formed in an annular shape, when the life raft lands on the water, air tends to accumulate in the inner periphery surrounded by the water bladder body, causing the water bladder body to become buoyant. This results in the most undesirable situation. Furthermore, since the bottom of the water bladder body is formed to be flat and wide, the sinking of the water bladder body into the water is slowed down, which promotes the formation of air pockets.

るものである。Problems to be solved by the invention This invention aims to solve the above-mentioned problems.When inflating an inflatable life raft on the sea surface, it can be kept upright without tipping over or inverting. Make sure to inflate at
The purpose is to allow seawater to rapidly flow into the stabilizing water bladder to quickly stabilize the life raft.

して成るものである。Means for solving the problems In order to solve the problems mentioned above, the present invention
The upper end of the water bladder body is suspended and fixed continuously at regular intervals on the outer surface of the bottom cloth fixed to the lower surface of the inflatable annular air column, and an inlet for seawater is opened in the outer peripheral wall of the water bladder body, This outer peripheral wall is formed into a wedge shape with a V-shaped side surface, and a heavy object is fixed to the lower end of the outer peripheral wall.
また重量物は、水嚢本体の下端に形成した挿入
袋内に、挿入口を開閉可能な止具で閉止し、取り
出し可能に挿入したものであつても良い。 Further, the heavy object may be inserted into an insertion bag formed at the lower end of the water bladder main body, and the insertion opening is closed with a stopper that can be opened and closed, so that it can be taken out.
作 用
本考案は上述のごとく構成したものであるか
ら、緊急時に船上から海面に投げ込まれた救命筏
が、充気装置を作動して膨脹すると、水嚢本体の
下端に重量物を固定し、救命筏の重心を低く形成
しているから、救命筏は横倒し、反転状態で膨脹
する事が無い。Function Since the present invention is configured as described above, when a life raft thrown from a ship onto the sea surface in an emergency is inflated by operating the air filling device, a heavy object is fixed to the lower end of the water bladder body. Since the center of gravity of the life raft is formed low, the life raft will not be tipped over on its side or inflated in an inverted state.
また仮に横倒し、反転状態で膨脹しても、重心
が低いために直ちに正立状態となり、遭難者の迅
速な乗り込みを可能とする。 Furthermore, even if the vehicle were to fall on its side and inflate in an inverted state, the low center of gravity immediately returns it to an upright state, allowing victims to quickly board the vehicle.
また救命筏が正立状態となると、水嚢本体の下
端に固定した重量物が海水中に水没するから、海
水流入口からは、海水が急速に充分流入すること
が可能となる。 Furthermore, when the life raft is in an erect state, the heavy object fixed to the lower end of the water bladder body is submerged in seawater, so seawater can rapidly and sufficiently flow in from the seawater inlet.
また水嚢本体は、底布の外面に、水嚢本体の上
端を一定間隔毎に連続して垂下固定したから、水
嚢本体で囲まれた内周にある空気は、一定間隔か
ら急速に外部に排出し、空気が溜まる事はなく、
水嚢本体が浮力を生じることも無い。 In addition, the upper end of the water bladder body is fixed to the outer surface of the bottom fabric so that it hangs down continuously at regular intervals. The air is exhausted without any air being trapped.
The water bladder itself does not generate any buoyancy.
また水嚢本体の外周壁を、側面Ｖ字型のくさび
状に形成しているから、水嚢本体の水中への沈下
を迅速に行う事ができる。 Further, since the outer circumferential wall of the water bladder main body is formed into a wedge shape with a V-shaped side surface, the water bladder main body can quickly sink into the water.
そのため、膨脹の初期に於いても、救命筏の激
しい揺動、反転等を生じる事は無く、水嚢本体は
救命筏の安定機能を生じるものである。 Therefore, even at the initial stage of inflation, the life raft does not undergo violent rocking or inversion, and the water bladder itself provides a stable function for the life raft.

浮力を生じることも無い。 In addition, the water bladder body is hung and fixed at regular intervals on the outer surface of the bottom fabric, so the air in the inner periphery surrounded by the water bladder body is rapidly discharged to the outside at regular intervals, preventing air from accumulating. There is no buoyancy in the area surrounded by the water sac body.
また水嚢本体の外周壁を、側面Ｖ字型のくさび
状に形成しているから、水嚢本体の水中への沈下
を迅速に行う事ができる。 Further, since the outer circumferential wall of the water bladder main body is formed into a wedge shape with a V-shaped side surface, the water bladder main body can quickly sink into the water.
