【０００１】[0001]
本考案は適度の回動抵抗力を与えられて回動する回動連結装置に関する。 The present invention relates to a rotation connecting device that is rotated by being given a proper rotation resistance force.
【０００２】[0002]
例えば全自動式などの大型の洗濯機では、洗濯槽の開閉蓋は、大寸法となるた め、あるいは上部に設置する乾燥機に衝突しないように、２つのプラスチック製 の蓋体を回動自在に連結した中折れ式になっている。 For example, in a large-scale washing machine such as a fully-automatic type, the opening and closing lid of the washing tub has a large size, or two plastic lids can be rotated so that it does not collide with the dryer installed above. It is a folding type connected to.
【０００３】 即ち、図８に示すように洗濯機本体１の洗濯槽２の後方上端の左右両側の取付 台３に、軸４によって第１の蓋体５の後端縁部５ａが内側の連結部５ａにおいて 回動自在に取付けられている。第１の蓋体５の前端には、垂直縁部５ｂが突設さ れ、この垂直縁部５ｂの複数個所において垂直縁部５ｂの下端から第２の蓋体６ 側へ腕７が突設されている。腕７には水平軸７ａが突設されている。That is, as shown in FIG. 8, the rear end edge portion 5 a of the first lid body 5 is connected to the inside of the mounting base 3 on the left and right sides of the rear upper end of the washing tub 2 of the washing machine body 1 by the shaft 4. It is rotatably attached at the portion 5a. A vertical edge portion 5b is provided at the front end of the first lid body 5, and an arm 7 is provided at a plurality of positions of the vertical edge portion 5b from the lower end of the vertical edge portion 5b toward the second lid body 6 side. Has been done. The arm 7 is provided with a horizontal shaft 7a.
【０００４】 第２の蓋体６の後端にも同様の垂直縁部６ａが突設され、その内側には、第２ の蓋体６の下面の前記腕７に対応する複数個所において軸穴（図示せず）を有す る連結板８が突設されていて、この軸穴に、第１の蓋体５の腕７の水平軸７ａが 回動自在に嵌合されていて、第１、第２の蓋体５、６は、図８に示すように閉じ た状態において垂直縁部５ｂ、６ａとが当接して、水平を保っている。A similar vertical edge portion 6a is also provided at the rear end of the second lid body 6, and inside thereof, shaft holes are formed at a plurality of positions on the lower surface of the second lid body 6 corresponding to the arms 7. A connecting plate 8 (not shown) is provided so as to project, and a horizontal shaft 7a of the arm 7 of the first lid 5 is rotatably fitted in this shaft hole. As shown in FIG. 8, the second lids 5 and 6 are kept horizontal by being in contact with the vertical edges 5b and 6a in the closed state.
【０００５】 第２の蓋体６の上面のやや後方側には、手を入れるための凹部９が設けられ、 この凹部９の前縁部に把手板９ａが取付けられている。A recess 9 for inserting a hand is provided on the slightly rear side of the upper surface of the second lid body 6, and a handle plate 9 a is attached to the front edge of the recess 9.
【０００６】 このような構造の中折れ式開閉蓋では、手を凹部９にいれて把手板９ａを図９ に示すように上方へ引き上げつつ後方へ押し込むと、第１の蓋体５は取付台３の 軸４を中心に時計方向に回動し、第２の蓋体６は水平軸７ａを中心として反時計 方向に回動し、第１、第２の蓋体５、６は次第に中折れ状態となり、第１の蓋体 ６をさらに後方へ押し込むと、図１０に示すように第１、第２の蓋体５、６が折 りたたまれて第１の蓋体５の後端が洗濯機本体１の後端の段部１ａに当接した開 き完了状態となる。In the center-folding type opening / closing lid having such a structure, when the hand is placed in the recessed portion 9 and the handle plate 9a is pulled up and pushed backward as shown in FIG. 9, the first lid 5 is attached to the mounting base. 3 pivots clockwise about the axis 4, the second lid 6 pivots counterclockwise around the horizontal axis 7a, and the first and second lids 5 and 6 gradually fold. Then, when the first lid 6 is pushed further rearward, the first and second lids 5 and 6 are folded and the rear end of the first lid 5 is pushed as shown in FIG. The washing machine main body 1 comes into contact with the stepped portion 1a at the rear end to complete the opening.
【０００７】 逆に、第２の蓋体６の把手板９ａを前方へ引くと、前記したのと逆の動作で第 １、第２の蓋体５、６は図８のように水平な閉じた状態となる。On the contrary, when the handle plate 9a of the second lid body 6 is pulled forward, the first and second lid bodies 5 and 6 are horizontally closed as shown in FIG. 8 by the operation reverse to that described above. It will be in a state of being.
【０００８】[0008]
しかしながら、このように中折れ蓋を開くには、第１の蓋体６の把手板９ａを 手で持って上方へ持ち上げつつ後方へ押し込むが、図９に示すように、水平軸７ ａを中心として第２の蓋体６が反時計方向に回動する中折れ動作の始めでは第１ の蓋体５を後方（矢印Ａ）へ押す力Ｆによる水平軸７ａを中心とする回転モーメ ントは、回動中心７ａと水平方向の力Ｆ間の距離が小さいので極めて小さいが、 中折れ動作が進むと共に回動中心点（水平軸７ａ）が上方へ移動するため、この 回転モーメントは急激に増大する。このため、図１０の状態まで押し込むとき、 蓋を開ける人の意志に反して第１、第２の蓋体５、６が互いに激しく衝突したり 、あるいは第２の蓋体６が取付台３に衝突して、大きな騒音を発生したり、軸機 構を痛めるという問題があった。 However, in order to open the middle folding lid in this manner, the handle plate 9a of the first lid body 6 is held by hand and lifted upward and pushed backward, but as shown in FIG. At the beginning of the middle folding operation in which the second lid body 6 rotates counterclockwise, the rotational moment about the horizontal axis 7a by the force F pushing the first lid body 5 rearward (arrow A) is The distance between the center of rotation 7a and the force F in the horizontal direction is small, so it is extremely small, but as the center of rotation (horizontal axis 7a) moves upward as the folding operation progresses, this rotational moment increases rapidly. . For this reason, when pushing to the state of FIG. 10, the first and second lid bodies 5 and 6 violently collide with each other against the will of the person who opens the lid, or the second lid body 6 is attached to the mounting base 3. There were problems such as collisions, loud noise, and damage to the shaft mechanism.
【０００９】 また、逆に閉じる際にも、図１０の開いた状態から第２の蓋体６の把手板９ａ を前方へ引くと、この引く距離に対する回動中心点（水平軸７ａ）の下方への移 動量は始めは小さいが、次第に閉じるにつれて急激に増大するため、蓋を閉じる 人の意志に反して第１、第２の蓋体５、６が洗濯槽２の上縁２ａに激しく衝突し て大きな騒音を発生したり、軸機構を痛めるという問題があった。Also, when the handle plate 9a of the second lid 6 is pulled forward from the open state of FIG. 10 even when it is closed, the lower side of the rotation center point (horizontal axis 7a) with respect to this pulling distance. The amount of movement to the first is small at first, but increases rapidly as it closes gradually. Therefore, the first and second lids 5 and 6 violently collide with the upper edge 2a of the washing tub 2 against the intention of the person closing the lid. Then, there were problems that a large noise was generated and the shaft mechanism was damaged.
【００１０】 本考案はこのような問題点を解決した回動連結装置を提供することを目的とし ている。It is an object of the present invention to provide a rotation connecting device that solves the above problems.
【００１１】[0011]

【００１２】[0012]
このようにしたため、第１の部材の収納枠体にダンパー外筒を嵌着し、第２の 部材の連結部を、前記ダンパー外筒内に収容されたダンパー内筒に連結すれば、 前記ダンパー外筒と前記ダンパー内筒間の粘性抵抗力によって、第１、第２の部 材間の回動は適度の抵抗力を受けるので、急激な回動による騒音の発生や軸機構 の痛みが生じなくなる。 Therefore, if the damper outer cylinder is fitted in the housing frame of the first member and the connecting portion of the second member is connected to the damper inner cylinder housed in the damper outer cylinder, the damper Due to the viscous resistance between the outer cylinder and the damper inner cylinder, the rotation between the first and second members receives an appropriate resistance, which causes noise and shaft mechanism pain due to sudden rotation. Disappear.

Since the edge plate portions 36a and 36b at both ends contact the wall portions 31a and 31b of the storage frame body 31, the storage frame body 31 is fixed in a loose state. Then, the horizontal shaft 30a of the arm 30 of the first lid 25 that fits into the rectangular cross-section shaft hole 46 of the damper inner cylinder 40 is inserted.
【００２８】 このように第１、第２の蓋体２５、２６は、第１の蓋体２５のアーム２７の水 平軸２７ａが第２の蓋体２６の連結板２８の軸穴に回動自在に取付けられると共 に、第１の蓋体２５のアーム３０の水平軸３０ａがダンパー内筒４０の軸穴４６ に挿入されているため、図８に示した従来装置と同様に第１、第２の蓋体２５、 ２６とは相対的に回動に可能になっている。As described above, in the first and second lids 25 and 26, the horizontal shaft 27 a of the arm 27 of the first lid 25 is rotated to the shaft hole of the connecting plate 28 of the second lid 26. While being freely attached, the horizontal shaft 30a of the arm 30 of the first lid 25 is inserted into the shaft hole 46 of the damper inner cylinder 40. Therefore, like the conventional device shown in FIG. It is rotatable relative to the second lids 25 and 26.
【００２９】 従って、第２の蓋体２６の凹部２９に手をいれて把手板２９ａを持って上方へ 持ち上げつつ後方へ押し込むと、図６に示すように第１、第２の蓋体２５、２６ は相対的に回動して中折れ状態となり、さらに第２の蓋体２６を後方へ押し込む と、図７に示すように完全に折りたたまれた開き状態となる。Therefore, when the hand is put in the concave portion 29 of the second lid body 26 and the handle plate 29a is lifted upward and pushed in backward, as shown in FIG. 6, the first and second lid bodies 25, 26 is relatively rotated to be in a center-folded state, and when the second lid 26 is further pushed rearward, it is in a completely folded open state as shown in FIG.

The viscous resistance body 45 between the damper inner cylinders 40 fixed to the horizontal shaft 30a of the side arm 30 produces an appropriate rotational resistance force, so that when the first and second lid bodies 25, 26 are opened. Contrary to the will of the person who opens the lid as described above, the first and second lid bodies 25 and 26 collide violently with each other, or the second lid body 26 violently collides with the mounting base 23 and becomes large. When making noise, damaging the shaft mechanism, or conversely, when closing the lid, the first and second lids 25, 26 violently hit the edge 22a of the washing tub 22 against the intention of the person closing the lid. It will not collide and generate loud noise or damage the shaft mechanism.
【００３１】 なお、前記実施例では、ダンパーによる連結を１ヶ所のみにして、他は通常の 軸による連結にしているが、すべて同様のダンパーによる連結にしてもよい。In the above embodiment, the dampers are connected at only one place and the other are connected by the normal shafts, but the same dampers may be used for connection.
【００３２】 なお、前記実施例では第１の蓋体２５側にアーム３０を設け、第２の蓋体２６ 側に収納枠体３１を設けたが、これを逆にしてもよい。また、アーム３０に水平 軸３０ａを設ける代りに矩形の穴を設け、ダンパー内筒４０の軸方向の一端から 矩形の水平軸を突設して、これを矩形の穴に嵌めるようにしてもよい。In the above embodiment, the arm 30 is provided on the first lid 25 side and the storage frame 31 is provided on the second lid 26 side, but this may be reversed. Further, instead of providing the horizontal shaft 30a on the arm 30, a rectangular hole may be provided, and a rectangular horizontal shaft may be projected from one end of the damper inner cylinder 40 in the axial direction, and the rectangular horizontal shaft may be fitted into the rectangular hole. .
【００３３】 また、前記実施例では、洗濯機の中折れ蓋の第１、第２の蓋体２５、２６間の 連結部に本考案の回動連結装置を用いた場合を示したが、第１の蓋体２５と洗濯 機本体２１の取付台２３との連結にも用いることもできる。また、洗濯機の蓋に 限らず、他の任意の二つの部材間の回動連結においても、一方に収納枠体３１を 設けてダンパー外筒を嵌着し、他方にダンパー内筒に固定する回動軸を設けるこ とによって、本考案の回動連結装置を適用することができることは勿論である。Further, in the above embodiment, the case where the rotary connecting device of the present invention is used for the connecting portion between the first and second lids 25 and 26 of the middle folding lid of the washing machine is shown. It can also be used to connect the one lid 25 and the mounting base 23 of the washing machine main body 21. Further, not only in the case of the lid of the washing machine, but also in the rotational connection between any other two members, the storage frame 31 is provided on one side and the damper outer cylinder is fitted and the other is fixed to the damper inner cylinder. Needless to say, the rotation connecting device of the present invention can be applied by providing the rotation shaft.
【００３４】[0034]
以上説明したように本考案の回動連結装置では、２つの部材間の回動連結にお いて、一方の部材に収納枠体を設けてダンパー外筒を着脱自在に嵌着固定し、他 方の部材に連結部を設けてダンパー内筒に連結することによって、粘性抵抗力に よって緩やかに回動するようにしたため、第１、第２の部材間の回動において激 しい衝突による騒音を生じたり、軸機構を痛めることがなくなる。 As described above, in the rotational coupling device of the present invention, in the rotational coupling between the two members, one member is provided with the storage frame body and the damper outer cylinder is detachably fitted and fixed. Since the member is provided with a connecting portion and connected to the damper inner cylinder so that the member can be gently rotated by viscous resistance, noise due to a violent collision is generated when the first member and the second member are rotated. It does not hurt the shaft mechanism.
