PROBLEM TO BE SOLVED: To provide an elevator door sill which satisfactorily provides reduction of a manufacturing cost and improvement of time and effort of conveyance and efficiency of an installment operation.SOLUTION: An elevator door sill 24 is applied for a landing door sill for a landing door of each floor on a hoistway of an elevator installed on a building and a car door sill for a riding car and, at the same time, causes a guide shoe provided on a lower end of the door of which the upper end side is hung and supported to slide in a groove 25 and guide the opening and closing of the door by a hanger having a hanger roller rolling on a rail frame arranged on a door upper part on a door device containing the landing door sill and the car door sill and a door rail fixed by the rail frame and the whole length is set to be shorter than a long-size opening and closing stroke with respect to an opening with W of the door. In the sill 24, both end parts directed to the outer side from an area corresponding to the opening width W of the groove 25 are provided with tapered parts 25a and, thereby, are formed so as to be gradually broadened and the entrance and exit of the guide shoe of the lower end of the door for a broadened part upon the door opening and closing is facilitated.SELECTED DRAWING: Figure 2

    【課題】製造コストの低減化と運搬の手間や設置作業効率の改善化とを十分に図り得るエレベータ用ドア敷居を提供する。【解決手段】このドア敷居24は、建物に設備されたエレベータの昇降路における各階床の乗場ドア用の乗場ドア敷居や乗りかごのかごドア用のかごドア敷居に適用されると共に、それらを含むドア装置においてドア上部に配置されるレール枠、及びそれに固定されたドアレールの上を転動するハンガローラを有したハンガによって、上端側が吊り下げられて支持されるドアの下端に設けられたガイドシューを溝25内で摺動させてドア開閉を案内するもので、全体長がドアの開口幅Wに対して長尺な開閉ストロークよりも短縮されている。敷居24では、溝25の開口幅Wに相当する領域から外方へ向かう両端部分がテーパ部25aを設けることで次第に広がるように形成され、ドア開閉時のドアの下端のガイドシューによる広がり部分への出入りを容易にする。【選択図】図2
