Description

エレベータのドア装置及びそのベルト掴み具Elevator door device and its belt grip
　本開示は、エレベータのドア装置及びそのベルト掴み具に関するものである。 This disclosure relates to an elevator door device and its belt gripper.
　従来のエレベータのドアオペレーターでは、固定部材に支持部材が固定されている。支持部材の断面形状は、Ｕ字形である。支持部材内には、押さえ部材が設けられている。また、支持部材には、一対のボルトがねじ込まれている。 In the conventional elevator door operator, the support member is fixed to the fixing member. The cross-sectional shape of the support member is U-shaped. A holding member is provided in the support member. Further, a pair of bolts are screwed into the support member.
　押さえ部材は、底面部と、一対の側面部とを有している。一対の側面部は、底面部から上方へ向けて突出している。また、一対の側面部の間隔は、上方へ行くに従って徐々に大きくなっている。一対の側面部の間には、ベルトが通されている。一対のボルトをねじ込むことによって、押さえ部材が固定部材に近付く方向へ移動する。これにより、ベルトは、固定部材に押し付けられ、固定部材に対して固定される（例えば、特許文献１参照）。 The holding member has a bottom surface portion and a pair of side surface portions. The pair of side surface portions project upward from the bottom surface portion. Further, the distance between the pair of side surface portions gradually increases toward the upper side. A belt is passed between the pair of side surfaces. By screwing in the pair of bolts, the holding member moves in the direction of approaching the fixing member. As a result, the belt is pressed against the fixing member and fixed to the fixing member (see, for example, Patent Document 1).

　エレベータのドアは、例えば、開閉動作の途中で敷居溝内の異物に戸の脚が衝突することによって、急停止することがある。このとき、ドアとベルトとの接続部には、ドアの開閉方向への大きな力が作用する。これに対して、上記のような従来のエレベータのドアオペレーターでは、ベルトは、単に押さえ部材と固定部材との間に挟み込まれているだけである。このため、ドアが急停止した場合に、固定部材に対してベルトがずれる恐れがある。 The elevator door may stop suddenly, for example, when the leg of the door collides with a foreign object in the threshold groove during the opening / closing operation. At this time, a large force acts on the connection portion between the door and the belt in the opening / closing direction of the door. On the other hand, in the conventional elevator door operator as described above, the belt is simply sandwiched between the pressing member and the fixing member. Therefore, if the door suddenly stops, the belt may shift with respect to the fixing member.
　本開示は、上記のような課題を解決するためになされたものであり、歯付きベルトに対するベルト掴み具のずれをより確実に抑制することができるエレベータのドア装置及びそのベルト掴み具を得ることを目的とする。 The present disclosure has been made to solve the above-mentioned problems, and to obtain an elevator door device and its belt gripper capable of more reliably suppressing the displacement of the belt gripper with respect to the toothed belt.

Further, the meshing member 43 of the second belt gripper 32 is arranged upside down with respect to the meshing member 43 of the first belt gripper 31.
　第１突起部４３ｃは、歯付きベルト２６の長手方向における第２対向部４２ｂの第１端面に当たっている。第２突起部４３ｄは、歯付きベルト２６の長手方向における第２対向部４２ｂの第２端面に当たっている。 The first protrusion 43c is in contact with the first end surface of the second facing portion 42b in the longitudinal direction of the toothed belt 26. The second protrusion 43d is in contact with the second end surface of the second facing portion 42b in the longitudinal direction of the toothed belt 26.
　これにより、第１突起部４３ｃ及び第２突起部４３ｄは、歯付きベルト２６の長手方向への掴み具本体４１に対する基部４３ａの移動を阻止している。第２対向部４２ｂの第２端面は、第２対向部４２ｂの第１端面とは反対側の端面である。 As a result, the first protrusion 43c and the second protrusion 43d prevent the base 43a from moving with respect to the gripping tool main body 41 in the longitudinal direction of the toothed belt 26. The second end face of the second facing portion 42b is an end face on the side opposite to the first end face of the second facing portion 42b.

Therefore, the frequency of retightening the pair of fixing bolts 44 can be reduced, and the labor of maintenance work can be reduced.
　また、噛み合い部材４３の断面であって、歯付きベルト２６の幅方向に直交する断面の形状は、歯付きベルト２６の幅方向に平行な方向の全体に渡って同じである。このため、噛み合い部材４３を、引き抜き加工により容易に製造することができる。 Further, the shape of the cross section of the meshing member 43, which is orthogonal to the width direction of the toothed belt 26, is the same over the entire direction parallel to the width direction of the toothed belt 26. Therefore, the meshing member 43 can be easily manufactured by drawing.
　また、突起部は、第１突起部４３ｃと第２突起部４３ｄとを有している。このため、開閉方向の両方向について、歯付きベルト２６に対する第１ベルト掴み具３１及び第２ベルト掴み具３２のずれを抑制することができる。 Further, the protrusion has a first protrusion 43c and a second protrusion 43d. Therefore, it is possible to suppress the deviation of the first belt gripping tool 31 and the second belt gripping tool 32 with respect to the toothed belt 26 in both the opening / closing directions.
　また、押し付けボルト４５は、押さえ部材４２の傾斜部４２ｃを押すことにより、楔のように機能し、第２対向部４２ｂを第１対向部４１ｂ側へ押し付け、噛み合い部材４３に歯付きベルト２６を押し付ける。 Further, the pressing bolt 45 functions like a wedge by pushing the inclined portion 42c of the pressing member 42, presses the second facing portion 42b toward the first facing portion 41b, and attaches the toothed belt 26 to the meshing member 43.

As a result, the work on the pressing bolt 45 can be performed from the front, and the first belt gripping tool 31 and the second belt gripping tool 32 can be easily attached to the toothed belt 26 even in a narrow space. In addition, the space around the car door device can be used efficiently.
　また、複数本のボルトが鉛直下向きに配置される構成と比べて、第１対向部４１ｂの幅寸法を小さくすることができる。これにより、かご室１１の奥行方向への第１ベルト掴み具３１及び第２ベルト掴み具３２の寸法を縮小することができる。かご室１１の奥行方向は、かご出入口の幅方向及び上下方向に直角な方向であり、図３の左右方向である。 Further, the width dimension of the first facing portion 41b can be reduced as compared with the configuration in which a plurality of bolts are arranged vertically downward. As a result, the dimensions of the first belt gripping tool 31 and the second belt gripping tool 32 in the depth direction of the car chamber 11 can be reduced. The depth direction of the car chamber 11 is a direction perpendicular to the width direction and the vertical direction of the car entrance, and is the left-right direction in FIG.
