Background technology
In general, the panel of the elevator car door of elevator is made of the plane, and elevator car door moves along the left and right directions rectilinearity and opens and closes.In recent years, the indoor design of building is variation, thus, has used the cylindrical circular cylindrical shape elevator of cage.In this cylindrical shape elevator, in order to accord with the shape of cage, elevator car door has been made the part of columnar cage, the section shape of the elevator car door of the face vertical with the lifting direction is circular-arc.And the circular elevator door that opens and closes along about the circular-arc track uses as elevator car door.One example of this cylindrical shape elevator can see the real record of opening clear 52-56862 communique of Japanese Patent for details.
Fig. 4 is the mode chart of basic structure one example of the driven for opening and closing device of expression circular elevator door.The circular elevator door is made of the threshold of the gate stop on round door panel, suspension door top, door guide rail, guiding door bottom etc.And the round door panel is by being arranged on the actuating device on the cage top board and carrying out driven for opening and closing with the linkage of actuating device interlock.
The concrete structure of the actuating device of circular elevator door is described with reference to Fig. 4.Arranged outside in columnar cage 101 has round door panel 102, and round door panel 102 can slide along the outer peripheral face of cage 101 by the door guide rail.About each drive link 104 symmetry shape setting of round door panel 102.Drive link 104 is exactly the connecting rod mechanism of the driving usefulness of round door panel 102, and the one end is the center of gyration of round door panel 102, with the center of cage 101 be that fulcrum C links, the other end links by the top of small rod 103 with round door panel 102.
In the space of the fan-shaped that forms by these 2 drive link 104, dispose door motor 105 and deceleration belt pulley 106.Door motor 105 and deceleration belt pulley 106 are fixed on the cage 101, and the pars intermedia of the peripheral part of deceleration belt pulley 106 and drive link 104 is linked by union lever 107 respectively.
In the actuating device of the circular elevator door of this structure, in case door motor 105 revolutions, the belt pulley 106 that then slows down turns round, with fulcrum C be the center drive link 104 of reversing by union lever 107 simultaneously to about round door panel 102 open and close.
Yet the driven for opening and closing device of traditional circular elevator door exists following problem.
At first, consistent for the center that makes columnar cage 101 with the center of gyration (fulcrum C) of drive link 104, need change the length of drive link 104 according to the size of cage 101.Therefore, for the different size of each cage 101, must redesign each member of drive link 104, small rod 103, door motor 105, deceleration belt pulley 106, union lever 107 etc.Like this, produced the problem that waste redesigns the used time and increases manufacturing cost.
Again, the fixed propulsive effort in order to obtain, the size of door motor 105 and deceleration belt pulley 106 must have certain above size, is restricted aspect miniaturization.And, in traditional actuating device, owing to be subjected to the center constructional restriction consistent of columnar cage 101 with the center of gyration of drive link 104, therefore, in the space beyond the space of the fan-shaped that is formed by 2 drive link 104, it is difficult wanting to dispose each member.Like this, in the less occasion of cage 101, be difficult to dispose the machine of the driving usefulness of door motor 105 and deceleration belt pulley 106 etc.
Again, if make the center of columnar cage 101 consistent with the center of gyration of drive link 104, as shown in Figure 4, the plane space that each member of actuating device occupies has only the pact of the plane space that cage 101 occupies about half.Like this, in case strengthen the size of cage 101, then each member of drive link 104, door motor 105, deceleration belt pulley 106, union lever 107 etc. maximizes, and actuating device itself becomes big assembly.Produced the problem that weight increases and cost rises of device thereupon.
And the occasion consistent with the center of gyration of drive link 104 at the center that makes columnar cage 101 if both sides' center does not reach the high precision unanimity, then can not successfully be carried out the on-off action of round door panel 102.Like this, during assembling or when installing, be difficult to carry out the operation of both sides' centrally aligned.And the operation when assembling is installed obviously descends, and causes cost to rise.
