Detailed description of the invention
Below, according to accompanying drawing, the embodiment of the anti-locking apparatus of door open running of the present invention is described.
As shown in Figure 1, the elevator being provided with an embodiment of the anti-locking apparatus of door open running of the present invention comprises: erect the guide rail 2 be arranged in hoistway 1; By such as lead boots 3a with the state that can slide be subject to this guide rail 2 support and above-below direction travel car frame 3; And the car 5 that the bottom surface 4 being subject to this car frame 3 is supported.Car 5 comprises the door 6 guided by threshold 9.Elevator hall 7 comprises and being guided and the door 8 kept by the storage frame 11 of elevator hall 7 by threshold 10.The door 6 of car 5 and the door 8 of elevator hall 7 are such as made up of double door respectively.
As shown in Figure 3, the anti-locking apparatus 20 of door open running of the present embodiment travelled under the state preventing car 5 from opening at the door 6 of car 5 comprises rotor 21, this rotor 21 is arranged at car 5 side near the end of the threshold 9 of the mobile terminal of door 6 when breakdown action forming car 5, rotate with the moving to direction near the end of above-mentioned threshold 9 of door 6 of car 5, and be crimped on the predetermined portion of elevator hall 7.
At least one party in the storage frame 11 that the door 8 of described predetermined portion by elevator hall 7 and the door 8 to elevator hall 7 keep is formed, such as, be made up of two sides.
As shown in Figure 3, the anti-locking apparatus 20 of the door open running of present embodiment comprises and to keep rotor 21 and to enable the turning cylinder 22 that freely rotates.Rotor 21 comprises: the engagement section 21a engaged with described predetermined portion; And to be connected with this engagement section 21a and to be arranged on main part 21c on turning cylinder 22, that be formed with elongated hole 21b.
In addition, present embodiment comprises moving body 24, this moving body 24 has that one end is inserted in the door 6 of car 5, the other end inserts adapter shaft 23 in the elongated hole 21b of the main part 21c of rotor 21, and can move in the lateral direction with the breakdown action of the door 6 of car 5.
As shown in (B) figure of Fig. 3, the inside of the door 6 of car 5 is provided with engaging portion 6a, this engaging portion 6a when the door 6 of car 5 carries out breakdown action to during the movement of mobile terminal by locking for one end of moving body 24.
In addition, as shown in (A) figure etc. of Fig. 3, present embodiment comprises elastic body 25, and this elastic body 25 is held on moving body 24, and is arranged to that one end can engage with the end of the door 6 of car 5, the other end can engage with the main part 21c of rotor 21.
On the upper position that described rotor 21 is such as arranged at the mobile terminal of another opening direction of 6 in the upper position of the mobile terminal of the opening direction of a door 6 in the double door 6 of car 5 and lower position and double door 6 and these 4 positions of lower position.Therefore, with the setting of this rotor 21 accordingly, 4 corresponding moving bodys 24 and elastic body 25 are set respectively.
When car 5 under steam, the door 6 of car 5 is held in the closed condition such as shown in (A) figure of (A) figure and Fig. 3 of Fig. 2.Now, such as, moving body 24 left be held in because of the application force of elastic body 25 to (A) figure of Fig. 3 move after state.Meanwhile, be arranged at the adapter shaft 23 of the other end of moving body 24 and engage with the end of the elongated hole 21b of rotor 21, rotor 21 has the tendency that the anticlockwise direction shown in (A) figure to Fig. 3 rotates slightly.Now, as shown in (A) figure of this Fig. 3, the engagement section 21a of rotor 21 is held in the state with the end separating of the door 8 of elevator hall 7.In addition, although not shown, but the engagement section 21a of rotor 21 is held in the state be separated with the storage frame 11 of elevator hall 7.
When car 5 is when predetermined floor is stopped and door 6 starts to open, under the effect of the end of door 6, elastic body 25 bends, under the effect of this elastic body 25, rotor 21 rotates along clockwise direction centered by turning cylinder 22 as shown in (B) figure of Fig. 3, moving body 24 moves to the right of (A) figure of Fig. 3, and, to the internal direction relative movement of door 6, soon, the end of moving body 24 is locking by the engaging portion 6a of the inside of door 6.During this period, adapter shaft 23 moves in the elongated hole 21b of rotor 21.
During mobile terminal when the door 6 of car 5 arrives breakdown action, under the effect of the elastic force of elastic body 25, and, end due to moving body 24 is subject to the pressing of the engaging portion 6a of the door 6 of car 5, makes the engagement section 21a of rotor 21 be crimped on the end of the door 8 of elevator hall 7 or be crimped on not shown storage frame 11.Utilizing this crimping, when the door 6 of car 5 is in opening, the braking force when car 5 is for travelling can being guaranteed.Namely, what present embodiment was engaged by the end of the door 8 of the engagement section 21a with elevator hall 7 that utilize rotor 21 and occurred crimp and the engagement section 21a of not shown rotor 21 engages with storage frame 11 and occurs crimps, ensure that the generation of braking force, and travel under the state that can prevent car 5 from opening at door 6 thus.
According to the present embodiment of above structure, utilize the door 6 with car 5 when breakdown action to mobile terminal move and the rotor 21 that rotates, namely utilizing the structure member of machinery, when not needing control circuit, travelling under the state that can prevent car 5 from opening at door 6.Thus, present embodiment can reduce manufacturing cost.
In addition, travel under the state that present embodiment can prevent car 5 from opening at door 6 when not needing the parts being arranged at guide rail 2 side.Thus, present embodiment can reduce component number, and this point also can make manufacturing cost reduce.In addition, present embodiment, by reduction component number, can also shorten making man-hour during assembling.This is also of value to reduction manufacturing cost.
