As shown in Figure 2, door switch unit 11 comprises: drive division 20, as the drive side panel 21 of switch gate, as the slave end panel 22 of switch gate, capture unit, the door open switch 23 that figure does not show.Drive division 20 comprises: be located at cage 2 cage 14 gangway 19 the top motor 24, be located at follow-up pulley 25, the endless-belt 26 of top of gangway 19 of the cage 14 of cage 2.
Motor 24 is located at an end of the Width of cage 14.Output shaft at motor 24 is equipped with drive pulley 27.Follow-up pulley 25 is located at the other end of the Width of cage 14.Follow-up pulley 25 rotates on the cage 14 that freely is supported in cage 2 around the axle center.Endless-belt 26 forms ring-type, strides to hang on drive pulley 27 and the follow-up pulley 25.Make drive pulley 27 rotations by motor 24, endless-belt 26 is around drive pulley 27 and follow-up pulley 25 circular flows.
That is, drive side panel 21 is closed under the state of gangway 19 at panel 21,22, is configured in the position than slave end panel 22 more close motor 24 sides.The belt clamp gripping member 28 that is fixed on endless-belt 26 is installed on the drive side panel 21.Drive side panel 21 moves in the horizontal direction with endless-belt 26 integratedly by belt clamp gripping member 28 is installed.
Capture unit links drive side panel 21 and slave end panel 22, so that when drive side panel 21 and endless-belt 26 moved in the horizontal direction integratedly, slave end panel 22 was mobile in linkage with drive side panel 21.Mobile integratedly by drive side panel 21 and endless-belt 26, drive side panel 21 and slave end panel 22 move at equidirectional along horizontal direction from the position of closing gangway 19 to the position of opening.Therefore, cage 2 uses the switch gate of the so-called single opened that moves at mutual equidirectional as the drive side panel 21 of switch gate and slave end panel 22.Again, in the present embodiment, panel 21,22 is when 19 positions of closing are to the position movement opened from the gangway, and the direction shown in drive side panel 21 and the slave end panel 22 arrow O in Fig. 2 moves.In the present embodiment, when panel 21,22 moved to off position from the position of opening gangway 19, the direction shown in drive side panel 21 and the arrow C of slave end panel 22 in Fig. 2 moved.Again, arrow O is the direction of opening gangway 19, and arrow C is the direction of closing gangway 19.
Door open switch 23 comprises: be installed on the main part 29 of drive side panel 21, from the prominent contact 30 that be not set up freely and that be biased to the directions of giving prominence to from main part 29 of this main part 29.Door open switch 23 to elevator control part 10 output expression contacts 30 whether submerge main part 29, be the information whether panel 21,22 is positioned at the position of closing gangway 19.Drive side panel 21 is positioned at the position of closing gangway 19, and the contact disk 31 (as shown in Figure 2) of the cage 14 by being fixed on cage 2 is so that like that the submerge main part 29 of the contact 30 of door open switch 23 shown in the dotted line of Fig. 3.The information that door open switch 23 submerges to elevator control part 10 output expression contacts 30, be the information that panel 21,22 is positioned at the position of closing gangway 19.Drive side panel 21 moves towards open position from the position of closing gangway 19, and door open switch 23 makes contact 30 outstanding from main part 29 by contact disk 31 shown in solid line among Fig. 3 like that.Door open switch 23 to elevator control part 10 output expression contacts 30 from main part 29 outstanding information, be the information that panel 21,22 is not positioned at the position of closing gangway 19.
As shown in Figures 2 and 3, door lock mechanism 12 comprises: interference member 32, locking component 33, hammer 38.Interference member 32 is installed on the cage 14 of cage 2.Interference member 32 is located at the top of gangway 19 of the cage 14 of cage 2.Interference member 32 consists of by the fixed part 34 of the top of the gangway 19 that is overlapped in cage 14 with from interference part 35 one that fixed part 34 is holded up.Fixed part 34 is fixed on the top of the gangway 19 of cage 14.
In the door lock mechanism 12 of above-mentioned formation, the acceleration/accel of arrow O direction does not act on the panel 21,22, owing to act on the gravity of hammer 38 grades, locking component 33 is arranged in the latch-release position shown in Fig. 3 solid line.Again, in the latch-release position, the length direction of the member body 36 of locking component 33 is parallel with vertical direction, and locking part 37 does not have in the horizontal direction not side by side with interference part 35.Therefore, locking component 33 is positioned at the latch-release position, though panel 21,22 from the position of closing gangway 19 to the position movement of opening, locking part 37 also can not interfered (contact) with interference part 35.Be positioned at the latch-release position, panel 21,22 is during from the position of closing gangway 19 to the position movement opened, and locking component 33 allows panels 21,22 to open gangway 19.Like this, to the acceleration/accel of the panel 21 of having closed gangway 19,22 effect arrow O directions, locking component 33 is positioned at and allows panel 21,22 to open the latch-release position of gangway 19.
So in the door lock mechanism 12, when earthquake etc. occured, the acceleration/accel of arrow O direction relatively acted on the panel 21,22 of having closed gangway 19 with respect to cage 14, this acceleration/accel also acts on hammer 38.Therefore, the other end 36b of the member body 36 of locking component 33 rotates towards the direction near follow-up pulley 25 centered by an end 36a.So the locking part shown in dotted lines in Figure 3 37 of locking component 33 turns to and interference part 35 side by side interference position in the horizontal direction.On the interference position, the above-mentioned acceleration/accel that acts on panel 21,22 arrow O direction surpasses the torque that motor 24 produces, even panel 21,22 moves to the arrow O direction of opening gangway 19, before the contact 30 of door open switch 23 was given prominence to, (contact) interfered in locking part 37 and interference part 35.Therefore, on the interference position, the locking part 37 of locking component 33 is interfered (contact) with interference part 35, and restriction panel 21,22 moves to the arrow O direction of opening gangway 19.Like this, when earthquake etc. occured, the acceleration/accel of arrow O direction relatively acted on the panel 21,22 of having closed gangway 19 with respect to cage 14, and door lock mechanism 12 pins panels 21,22.
Again, in the door lock mechanism 12, be positioned at the state of interference position at locking component 33, do not had to act on the words of the acceleration/accel of the panel 21 of having closed gangway 19,22 arrow O direction, by acting on the gravity of hammer 38, so that locking component 33 rotates to the latch-release position from interference position.
Further, door lock mechanism 12 is provided with a pair of restriction projection 39 at drive side panel 21, and the member body 36 of these restriction projection 39 restriction locking components 33 surpasses the latch-release position and interference position ground rotates.
In the door lock mechanism 12 of the elevator 1 of embodiment 1, the acceleration/accel of opening the arrow O direction of gangway 19 acts on the panel 21,22 of having closed gangway 19, and locking component 33 turns to locking component 33 and is installed in the interference position of interference member 32 interference of cage 2.Therefore, even to the panel 21 of having closed gangway 19, the acceleration/accel that the arrow O direction of gangway 19 is opened in 22 effects, door lock mechanism 12 also can limit panel 21,22 with locking component 33 interference by interference member 32 and move.Therefore, even because earthquake etc. acts on panel 21,22 so that open the acceleration/accel of the arrow O direction of gangway 19, door lock mechanism 12 also can suppress to have closed the panel 21,22 of gangway 19 and open.Therefore, even earthquake etc. occurs in the lifting of cage 2, door lock mechanism 12 can suppress also to arrive before the hall of the most close layer that panel 21,22 is opened, cage 2 stops.
Again, the acceleration/accel of opening the arrow O direction of gangway 19 does not act on the panel 21,22 of having closed gangway 19, and the locking component 33 of door lock mechanism 12 is positioned at the latch-release position.Therefore, the acceleration/accel of opening the arrow O direction of gangway 19 does not act on the panel 21,22 of having closed gangway 19, and door lock mechanism 12 can not limit panel 21 by interference member 32, locking component 33, switch (permission) is carried out in 22 pairs of gangways 19.Therefore, in the door lock mechanism 12, the acceleration/accel of opening the arrow O direction of gangway 19 does not act on the panel 21,22 of having closed gangway 19, and panel 21,22 is switch gangway 19 positively.
Further, in the door lock mechanism 12, an end 36a of locking component 33 rotates and is installed in freely on the drive side panel 21, and hammer 38 is installed on the other end 36b of locking component 33.Therefore, the locking component 33 of door lock mechanism 12 can positively rotate between interference position and latch-release position.
Again, the acceleration/accel of opening the arrow O direction of gangway 19 does not act on panel 21,22, and door lock mechanism 12 is by acting on the gravity of hammer 38, and locking component 33 turns to the latch-release position from interference position.Therefore, the acceleration/accel of opening the arrow O direction of gangway 19 does not act on panel 21,22 words, the interference member 32 of door lock mechanism 12 and locking component 33 do not limit panel 21, switch is carried out in 22 pairs of gangways 19, and panel 21,22 is switch gangway 19 positively.
[variation 1]
Then, the door lock mechanism of the elevator of the variation 1 of embodiment 1 described.Fig. 4 is the block diagram of formation of door lock mechanism of cage of elevator that the variation 1 of embodiment 1 is shown.Again, among Fig. 4, the part identical with above-mentioned embodiment 1 all adopts prosign and the description thereof will be omitted.
In the variation 1 of embodiment 1, as shown in Figure 4, door lock mechanism 12 comprises the tension spring 40 as application of force unit.Tension spring 40 is set to the member body 36 more close motors 24 than locking component 33.One end of tension spring 40 is installed on drive side panel 21 and the other end, and to be installed on hammer 38 be the other end 36b of the member body 36 of locking component 33.The other end 36b of member body 36 that tension spring 40 makes locking component 33 is the 24 side application of forces along horizontal direction to motor.That is, when panel 21,22 is positioned at the position of closing gangway 19, the torque that tension spring 40 and motor 24 produce inversely, to locking component 33 from interference position towards the latch-release position application of force.
The door lock mechanism 12 of the variation 1 of embodiment 1 except the effect of embodiment 1, also comprise from interference position towards the latch-release position tension spring 40 to locking component 33 application of forces.Therefore, door lock mechanism 12 is by the suitable application of force of change tension spring 40, can suitably change locking component 33 turns to the arrow O direction of interference position from the latch-release position the size of acceleration/accel.Therefore, door lock mechanism 12 is by suitably changing the application of force of tension spring 40, can suitably change the size of the acceleration/accel of the arrow O direction that the restriction panels 21,22 such as locking component 33 open.
[variation 2]
