The invention relates to a shaft door (4) with a door protection device (1) for an elevator (5) and to an elevator (5) with such a shaft door (4). The door protection device (1) comprises a force sensor (2) and a safety switch (3), wherein the force sensor (3) comprises a contact unit (7) and a spring mechanism (8) with a spring (8a). The force sensor (2) is able to sense the presence of an object (6) clamped by the shaft door (4) in such a way that the force sensor (2) is mounted on the shaft door (4), and wherein the contact element (7) contacts the clamped object (6) as a result of the shaft door (4) being closed, such that the contact element (7) is able to transmit a force to the spring (8a), and the spring mechanism (8) is capable of activating the safety switch (3) to send a door opening command to a door operator (9) of the elevator (5) when the force transmitted to the spring (8a) exceeds the stiffness of the spring (8a).

    本发明涉及一种用于电梯(5)的具有门防护装置(1)的竖井门(4)和一种具有这种竖井门(4)的电梯(5)。门防护装置(1)包括力传感器(2)和安全开关(3),其中力传感器(3)包括接触单元(7)和具有弹簧(8a)的弹簧机构(8)。力传感器(2)能够以将力传感器(2)安装在竖井门(4)处的方式感测被该竖井门(4)夹住的物体(6)的存在,其中接触元件(7)由于竖井门(4)关闭而接触被夹住的物体(6),使得接触元件(7)能够将力传递到弹簧(8a),以及弹簧机构(8)能够在传递到弹簧(8a)的力超过弹簧(8a)的刚度时激活安全开关(3),以向电梯(5)的门操作器(9)发送门打开命令。
