(horizontal rotational shaft link rod)
In Fig. 1, the lower horizontal axle rotating link 8 that is arranged on car door 1 bottom is fixed on car door 1 by S. A. 8a, and by pivot suspension for rotating centered by S. A. 8a in vertical surface.On the S. A. 8b that is positioned at lower horizontal axle rotating link 8 upper ends, be connected with bottom and connect link rod 10, and the S. A. 10a of bottom connection link rod 10 is connected with safety shoe 16.
In addition, the upper level axle rotating link 9 that is arranged on car door 1 top is rotated axle 9a and is fixed on car door 1, and by pivot suspension for rotating centered by S. A. 9a.On the S. A. 9b that is positioned at upper level axle rotating link 9 tops, be connected with top and connect link rod 11, and the S. A. 11a of top connection link rod 11 is connected with safety shoe 16.
(vertical axis revolving link rod)
In addition, in Fig. 1, the lower vertical axle rotating link 12 that is arranged on car door 1 bottom is rotated axle 12a and is fixed on car door 1, and by pivot suspension for rotating centered by S. A. 12a in horizontal surface.On the S. A. 12b of this lower vertical axle rotating link 12, be connected with bottom and connect link rod 14, and the S. A. 14a of bottom connection link rod 14 is connected with safety shoe 16.
The upper vertical axle rotating link 13 that is arranged on car door 1 top is rotated axle 13a and is fixed on car door 1, and by pivot suspension for rotating centered by S. A. 13a.On the S. A. 13b that is positioned at these upper vertical axle rotating link 13 tops, be connected with top and connect link rod 15, and the S. A. 15a of top connection link rod 15 is connected with safety shoe 16.
According to said structure, safety shoe 16 can utilize and be connected link rod 10 and lower vertical axle rotating link 12 with bottom by lower horizontal axle rotating link 8 and be connected bottom link mechanism that link rod 14 forms with bottom and be connected link rod 11 and upper vertical axle rotating link 13 with top by upper level axle rotating link 9 and be connected the top link mechanism that link rod 15 forms with top and smoothly and reliably carry out parallel along horizontal direction.
In addition, safety shoe 16 can turn back to the position before moving under the effect of the deadweight of lower horizontal axle rotating link 8, bottom connection link rod 10, upper level axle rotating link 9, top connection link rod 11 and safety shoe 16.
Below the S. A. 8a of pivot suspension lower horizontal axle rotating link 8, be provided with hill holder 18, above the S. A. 9a of upper level axle rotating link 9, be provided with hill holder 19.Hill holder 18 limits the extrusion position of safety shoe 16 by the rotation of restriction lower horizontal axle rotating link 8.On the other hand, hill holder 19 limits the going-back position of safety shoe 16 by the rotation of restriction upper level axle rotating link 9.
As depicted in figs. 1 and 2, in the lower left of S. A. 8a and in the left side of lower horizontal axle rotating link 8, the detector switch 17 retreating for detection of safety shoe 16 is arranged on car door 1.This detector switch 17 is arranged on when on the position that safety shoe 16 contacts with lower horizontal axle rotating link 8 during in normal condition, and in conducting (ON) state.Detector switch 17 is connected with the control setup 20 of controlling car door switching.
(movement structure of safety shoe)
Below the movement structure of the safety shoe in embodiments of the present invention and detector switch is described.The details drawing of car door bottom when Fig. 5 is the state of safety shoe in retreating from car door, Fig. 6 is the birds-eye view of the top link mechanism of presentation graphs 5, Fig. 7 is the upward view of the bottom link mechanism of presentation graphs 5.Fig. 5~Fig. 7 all represents the foreign matter detected state of safety shoe from car door end retreats.
Under the state of opening completely at car door 1 or at car door 1, carrying out under the state of closing movement, pressed by passenger's health at safety shoe 16 or be subject to the impact of the external factor such as foreign matter, obstacle and when opening direction and retreat towards elevator door, the counterclockwise rotation centered by S. A. 8a and S. A. 9a respectively of lower horizontal axle rotating link 8 and upper level axle rotating link 9.By this rotation, as shown in Figure 5, contacting between lower horizontal axle rotating link 8 and detector switch 17 is disengaged, and detector switch 17 becomes cut-out (OFF) state.Now, according to the output of detector switch 17, by control setup 20, car door 1 is controlled to the state (static cost control) that can not close or carries out the control (oppositely controlling) that car door 1 is opened.This control logic can easily consist of the software moving on microcomputer up to now.
As mentioned above, according to present embodiment, safety shoe 16 can be connected link rod 15 and lower vertical axle rotating link 12 by upper vertical axle rotating link 13 and be connected link rod 14 with bottom and smoothly and reliably carry out parallel along horizontal direction with top.
