【０００１】[0001]

【考案が属する技術分野】 本考案は、機械類の筐体や家具本体等の固定枠 体に対して扉や蓋等の可動物を閉鎖位置に保持するのに用いられる扉等の保持装 置に関するものである。[Technical field to which the present invention pertains] The present invention relates to a holding device such as a door used to hold a movable object such as a door or a lid in a closed position with respect to a fixed frame such as a housing of a machine or a furniture body. It is about.

【０００２】[0002]

【従来の技術】 従来の扉等の保持装置では、受座体の割溝の両側にボール 収容部を設け、該ボール収容部に収容したボールをバネによって割溝方向に摺動 付勢し、挿込体に設けた係合突起の側面に該ボールを係合させることによって、 可動物を固定枠体に対し保持している。2. Description of the Related Art In a conventional holding device for a door or the like, a ball accommodating portion is provided on both sides of a split groove of a seat, and a ball accommodated in the ball accommodating portion is slidably urged in a split groove direction by a spring. The movable object is held on the fixed frame by engaging the ball with the side surface of the engagement projection provided on the insertion body.

【０００３】[0003]

【考案が解決しようとする課題】 この従来の扉等の保持装置では、挿込体 側の係合突起と受座体側のボールとの係合が容易に解除されないようにするため 、ボール付勢用バネとして強力なものが必要であった。[Problem to be Solved by the Invention] In this conventional holding device for a door or the like, the ball urging is performed so that the engagement between the engagement protrusion on the insertion body side and the ball on the receiving body side is not easily released. A strong spring was required.

【０００４】 このため扉の開閉にともない、挿込体側の係合突起と受座体側のボールの接触 係合部分が摩耗して、扉を閉鎖位置に保持する力が次第に弱まっていくという難 点があった。 したがって本考案の目的は、挿込体と受座体の接触係合部分の摩耗が抑制され 、耐久性に優れている扉等の保持装置を提供することである。[0004] Therefore, as the door is opened and closed, the contact engagement portion between the engagement protrusion on the insertion body side and the ball on the receiver body wears, and the force for holding the door in the closed position gradually weakens. was there. Accordingly, an object of the present invention is to provide a holding device such as a door which is excellent in durability, in which wear of a contact engagement portion between an insertion body and a receiving body is suppressed.

The seat 1 comprises an insert 11 fixed to the other of the movable member 17 and the fixed frame 18. The seat 1 is provided with a split groove 36 at a central portion. Receiving holes 4 and 5 are provided in the left and right side wall portions 2 and 3, and conical-shaped enlarged diameter portions 4 a and 5 a are formed at inner ends of the receiving holes 4 and 5. , Latches 12, 13 and case 19, and hemispherical tip portions 27, 28 engaged and disengaged from conical-surface-diameter enlarged portions 4 a, 5 a of receiving holes 4, 5 of seat body 1. 13.

【０００６】 該ラッチ支持枠８の左右側壁部に座部６，７を有する受孔９，１０を設け、ラ ッチ支持枠８の中央主体部分にラッチの入り込み過ぎを阻止する制止突起２２， ２３を設け、ラッチ支持枠８に収容したラッチ１２，１３を両者間に挿入した圧 縮コイルバネ１４によって外側方向に摺動付勢し、ラッチ１２，１３の基端部外 周に前記座部６，７に当接する抜け止め鍔部２０，２１を設け、ラッチ支持枠８ を収容するケース１９には、ラッチ１２，１３の半球状先端部２７，２８が突出 する受孔１５，１６を左右側壁部に設ける。Receiving holes 9, 10 having seats 6, 7 are provided on the left and right side walls of the latch support frame 8, and stop protrusions 22, which prevent the latch from excessively entering the central main portion of the latch support frame 8. 23, the latches 12 and 13 accommodated in the latch support frame 8 are slid outwardly by a compression coil spring 14 inserted between the latches 12 and 13, and the seats 6 are attached to the outer periphery of the base ends of the latches 12 and 13. In the case 19 for holding the latch support frame 8, the receiving holes 15, 16 from which the hemispherical tips 27, 28 of the latches 12, 13 protrude, are formed on the left and right side walls. Section.

【０００７】 この扉等の保持装置は、図１に示したように可動物１７が固定枠体１８に向か って閉鎖されるとき、閉鎖動作の終端で受座体１と挿込体１１が相接近し、挿込 体１１の前面部２４が受座体１の中央部の割溝３６に入り込む。そして、受座体 １の側壁部２，３の開口縁部２５，２６に挿込体１１のラッチ１２，１３の半球 状先端部２７，２８が押し入ると、ラッチ１２，１３は挿込体１１内の圧縮コイ ルバネ１４の付勢に抗してケース１９の受孔１５，１６内を後退摺動する。When the movable member 17 is closed toward the fixed frame 18 as shown in FIG. 1, the holding device such as the door has the receiving member 1 and the insertion member 11 at the end of the closing operation. Are close to each other, and the front face portion 24 of the insertion body 11 enters the split groove 36 at the center of the receiving body 1. When the hemispherical tips 27 and 28 of the latches 12 and 13 of the insertion body 11 are pushed into the opening edges 25 and 26 of the side walls 2 and 3 of the receiving body 1, the latches 12 and 13 are inserted into the insertion body 11. The housing 19 slides backward in the receiving holes 15 and 16 of the case 19 against the bias of the compression coil spring 14 therein.

【０００８】 ラッチ１２，１３の半球状先端部２７，２８が受座体１の受孔４，５の円錐面 状拡径部４ａ，５ａに係合したとき、ラッチ１２，１３は再び前進摺動して半球 状先端部２７，２８が前記受孔４，５の内周部に当接する。かくして、扉等の可 動物１７は図２に示すようにその全閉位置に保持される。When the hemispherical tips 27 and 28 of the latches 12 and 13 are engaged with the conically-shaped enlarged diameter portions 4 a and 5 a of the receiving holes 4 and 5 of the seat 1, the latches 12 and 13 slide forward again. As a result, the hemispherical tips 27 and 28 come into contact with the inner peripheral portions of the receiving holes 4 and 5. Thus, the movable animal 17 such as a door is held at its fully closed position as shown in FIG.

【０００９】 この可動物１７を開放操作する時、受座体１の側壁部の受孔４，５の円錐面状 拡径部４ａ，５ａの内周面によって半球状先端部２７，２８を押されたラッチ１ ２，１３は、挿込体１１の受孔１５，１６内に一時的に後退摺動し、半球状先端 部２７，２８が受座体１の開口縁部２５，２６を越えたとき、圧縮コイルバネ１ ４の付勢によって再び前進摺動し、可動物１７は開放される。挿込体１１が受座 体１から脱出したとき、基端部外周の抜け止め鍔部２０，２１が受孔９，１０端 部の座部６，７に当接するため、ラッチ１２，１３は待機位置に保持される。When the movable member 17 is opened, the hemispherical tip portions 27 and 28 are pushed by the inner peripheral surfaces of the conical enlarged portions 4 a and 5 a of the receiving holes 4 and 5 in the side wall portion of the seat 1. The latches 12 and 13 temporarily slide backward into the receiving holes 15 and 16 of the insertion body 11, and the hemispherical tips 27 and 28 pass over the opening edges 25 and 26 of the receiving body 1. Then, the movable coil 17 slides forward again by the bias of the compression coil spring 14, and the movable member 17 is opened. When the insertion body 11 escapes from the receiving body 1, the retaining flanges 20 and 21 on the outer periphery of the base end abut against the seats 6 and 7 at the ends of the receiving holes 9 and 10. It is held in the standby position.
