スクラッシャに関するものである。[Detailed explanation of the invention] This invention is an ice crusher. Specifically, ice cubes are input through the input port at the top, the bundle is rotated to crush the ice cubes with a rotating blade, and the crushed fine ice is received in a container at the bottom. This is about an ice crusher designed to remove ice.

従来、この種のアイスクラッシャでは、回転刃を有する
主軸は、バンドルと直結されたもの、あるいは歯車機構
を介してバンドルと連結されたものが一般的である。Conventionally, in this type of ice crusher, a main shaft having a rotating blade is generally connected directly to the bundle or connected to the bundle via a gear mechanism.

このような構造では、バンドルを回せば回転刃が必ず回
転するため、手を投入口に入れたまま不用意にバンドル
を回転させると、指を負傷する危険があり、実際にこの
ような事故が発生していた。With this type of structure, the rotating blade always rotates when the bundle is turned, so if you carelessly rotate the bundle while your hand is in the slot, there is a risk of injury to your fingers, and such accidents have never occurred. It was occurring.

本考案はかかる従来の欠点に鑑みてなされたもので、氷
投入口の蓋体を閉じない限り、バンドルを回しても回転
刃が回転しないようにし、不注意による指等の負傷を防
止したアイスクラッシャを提供することを目的とする。The present invention has been developed in view of these conventional drawbacks, and the rotating blade does not rotate even when the bundle is turned unless the lid of the ice inlet is closed, thereby preventing inadvertent injuries to fingers, etc. The purpose is to provide a crusher.

以下、本考案を一実施例である添付図面にしたがって説

図面において、１は本体ケースで、その上部には氷投入
口２を有し、下部には細氷容器３が挿脱自在に収納され
ている。In the drawings, reference numeral 1 denotes a main body case, which has an ice inlet 2 at its upper part and a thin ice container 3 which is removably housed at its lower part.

４は氷投入口２を開閉する蓋体で、その一端部は支軸５
によって本体ケース１の上端部に軸支されており、蓋体
４の下面側には連結ピン６が一体に突設されている。Reference numeral 4 denotes a lid body for opening and closing the ice inlet 2, and one end thereof is attached to a support shaft 5.
It is pivotally supported by the upper end of the main body case 1, and a connecting pin 6 is integrally provided on the lower surface side of the lid 4.

本体ケース１の内部には主軸１０が回転自在に軸支され
ており、この主軸１０には複数の回転刃１１が一定間隔
をあけて取付けられ、主軸１０の一端部には平歯車から
なる主歯車１２が固定されている。A main shaft 10 is rotatably supported inside the main body case 1. A plurality of rotary blades 11 are attached to the main shaft 10 at regular intervals, and a main shaft made of a spur gear is attached to one end of the main shaft 10. Gear 12 is fixed.

また、本体ケース１には、上記主軸１０と平行に副軸１
３が回転自在に軸支されており、この副軸１３の一端部
にはハンドル１４が固定されている。In addition, a sub-shaft 1 is provided in the main body case 1 in parallel with the main shaft 10.
3 is rotatably supported by a shaft, and a handle 14 is fixed to one end of this subshaft 13.

副軸１３の中央部は断面半月状に切り欠かれており、こ
の切欠部分に上記主歯車１２と噛合可能な副歯車１５が
軸方向に移動可能に挿通されている。The center portion of the subshaft 13 is cut out to have a half-moon shape in cross section, and a sub gear 15 that can mesh with the main gear 12 is inserted into this cut portion so as to be movable in the axial direction.

上記副軸１３には、上記副歯車１５と隣接して伝達部材
１６が回転自在に挿通されており、この伝達部材１６の
第４図右側端面には傾斜面１７が形成されている。A transmission member 16 is rotatably inserted into the secondary shaft 13 adjacent to the secondary gear 15, and an inclined surface 17 is formed on the right end surface of the transmission member 16 in FIG.

また、上記副歯車１５と軸受リング１８との間には、副
歯車１５を主歯車１２との噛合方向に付勢するスプリン
グ１９が設けられている。Further, a spring 19 is provided between the secondary gear 15 and the bearing ring 18 to bias the secondary gear 15 in the direction of meshing with the main gear 12.

副軸１３のハンドル側とは反対側の端部には操作部材２
０の下端筒部２１が挿通されており、この下端筒部２１
の側部に形成した傾斜面２２は、上記スプリング１９の
バネ力により上記伝達部材１６の傾斜面１７と圧接し、
操作部材２０は常時下方へ付勢されている。An operating member 2 is provided at the end of the subshaft 13 opposite to the handle side.
0 is inserted through the lower end cylinder part 21.
The inclined surface 22 formed on the side of the transmission member 16 is pressed against the inclined surface 17 of the transmission member 16 by the spring force of the spring 19,
The operating member 20 is always urged downward.

操作部材２０はその上端部に設けたガイドリブ２３と下
端部に設けた軸部２４とによって、本体ケース１に対し
上下動自在に案内されている。The operating member 20 is guided so as to be vertically movable relative to the main body case 1 by a guide rib 23 provided at its upper end and a shaft portion 24 provided at its lower end.

操作部材２０の上端には横方向に長孔２５が形成されて
おり、この長孔２５に蓋体４の連結ピン６が嵌入してい
る。A long hole 25 is formed in the upper end of the operating member 20 in the lateral direction, and the connecting pin 6 of the lid 4 is fitted into this long hole 25.

ここで、上記構成からなるアイスクラッシャの作動を説
明する。Here, the operation of the ice crusher having the above configuration will be explained.

受態においては、スプリング１９のバネ力により操作部
材２０は押し下げられた位置にあり、蓋体４は氷投入口
２を閉鎖している。In the receiving position, the operating member 20 is in a depressed position due to the spring force of the spring 19, and the lid 4 closes the ice inlet 2.

そして、副歯車１５はスプリング１９により付勢されて
主歯車１２と噛合状態にある。The auxiliary gear 15 is biased by the spring 19 and is in mesh with the main gear 12.

この状態でハンドル１４を回すと副歯車１５および主歯
車１２を介して回転力が伝達され、回転刃１１が回転し
、氷投入口２に投入された氷塊は割砕され、細氷は細氷
容器３に受は取られる。When the handle 14 is turned in this state, rotational force is transmitted through the secondary gear 15 and the main gear 12, the rotary blade 11 rotates, the ice cubes put into the ice inlet 2 are crushed, and the ice cubes are crushed. The receiver is placed in container 3.

いま、蓋体４を開くと、連結ピン６にて連結された操作
部材２０が上昇し、傾斜面１７．２２の作用により伝達
部材１６および副歯車１５は第４図矢印方向に移動する
。Now, when the lid 4 is opened, the operating member 20 connected by the connecting pin 6 rises, and the transmission member 16 and the secondary gear 15 move in the direction of the arrow in FIG. 4 due to the action of the inclined surface 17.22.

そのため、副歯車１５と主歯車１２との噛合が外れ、こ
の状態でハンドル１４を回しても、副軸１３が空回りす
るだけで回転刃１１は回転しない（第５図参照）。Therefore, the auxiliary gear 15 and the main gear 12 are disengaged, and even if the handle 14 is turned in this state, the auxiliary shaft 13 only rotates idly and the rotary blade 11 does not rotate (see FIG. 5).

したがって、氷投入口２に手を入れて不用意にハンドル
１４を回しても、負傷する危険はない。Therefore, even if the user inserts his/her hand into the ice inlet 2 and turns the handle 14 carelessly, there is no risk of injury.

蓋体４への開き力を解除すると、スプリング１９のバネ
力により副歯車１５および伝達部材１６は第５図右方へ
押され、副歯車１５が主歯車１２と噛合するとともに、
操作部材２０が押し下げられて蓋体４は閉じる。When the opening force on the lid body 4 is released, the secondary gear 15 and the transmission member 16 are pushed to the right in FIG. 5 by the spring force of the spring 19, and the secondary gear 15 meshes with the main gear 12.
The operating member 20 is pushed down and the lid 4 is closed.

このとき、主歯車１２と副歯車１５とが共に平歯車のた
め、両歯車の端面どおしが当って噛合しない場合が生じ
ることがあるが、この場合にはハンドル１４をいずれか
の方向に若干回せば、スプリング１９により付勢された
副歯車１５が主歯車１２と噛合し、上記の不具合は解消
される。At this time, since both the main gear 12 and the auxiliary gear 15 are spur gears, the end surfaces of both gears may come into contact with each other and do not mesh. In this case, the handle 14 may be rotated in either direction. By slightly turning the gear, the secondary gear 15 biased by the spring 19 will mesh with the main gear 12, and the above-mentioned problem will be resolved.

なお、上記実施例では、副歯車１５と操作部材２０との
間に伝達部材１６を介在させたが、この伝達部材１６を
省略して操作部材２０が直接副歯車１５を移動させるよ
うにしてもよい。In the above embodiment, the transmission member 16 is interposed between the secondary gear 15 and the operating member 20, but the transmission member 16 may be omitted and the operating member 20 may directly move the secondary gear 15. good.

また、主歯車１２と副歯車１５とを共に平歯車としたが
、これらを傘歯車としても同様の効果が得られる。Moreover, although both the main gear 12 and the auxiliary gear 15 are spur gears, the same effect can be obtained by using these as bevel gears.

ただし、この場合には主軸１０と副軸１３とは直交方向
に配置される。However, in this case, the main shaft 10 and the sub-shaft 13 are arranged in orthogonal directions.

以上の説明で明らかなように、本考案によれば、蓋体を
開いた時にはハンドルの回転力は回転刃に伝達されず、
蓋体が閉じた時のみ回転力が伝達されるようにしたので
、従来のように氷投入口に手を入れたまま不用意にハン
ドルを回転させても回転刃が回転せず、指等を負傷する
危険がなく安全である。As is clear from the above explanation, according to the present invention, when the lid is opened, the rotational force of the handle is not transmitted to the rotary blade.
The rotational force is transmitted only when the lid is closed, so even if you carelessly turn the handle with your hand in the ice slot, the rotating blade will not rotate, preventing your fingers from rotating. It is safe and there is no risk of injury.
