Abstract

PROBLEM TO BE SOLVED: To provide an elevator door device in which the facing relationship to the peripheral surface of a door closing side guide pulley is maintained and a low-speed door is constrained by the movement of a high-speed door even if an interlocking function is lost caused by fracture of a transmission strap body for interlockingly operating the high-speed door and the low-speed door with each other and even if an interlocking element is deformed. SOLUTION: Even if an interlocking function for a high-speed door 3 and a low-speed door is lost caused by fracture of a transmission strap body 10, and also even if tilting deformation is generated on a hanger 8 along the entering/leaving direction of an entrance 1, the facing relationship between an interlocking element 15 and the peripheral surface of a door closing side guide pulley 12 is maintained. Accordingly, even if the interlocking function for the high-speed door 3 and the low-speed door 4 is lost and even if deformation in the direction along the entering/leaving direction of the entrance 1 is generated on the hanger 8, the movement of the low-speed door 4 in relation to the movement of the high-speed door 3 is constrained. Therefore, discrepancy to be generated caused by the movement of only the low-speed door 4 regardless of the movement of the high-speed door 3 is prevented.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 FIG. 1 to 3 show an example of an embodiment of the present invention. FIG. 1 is a front view of a main part, and FIG.
FIG. 3 is an enlarged view of a cross section taken along the line B, and FIG.
FIG. In the drawing, reference numeral 1 denotes an entrance of an elevator, 2 is a door pocket formed on one side of the entrance 1 and accommodated when a sliding door described later is opened, and 3 is a high-speed door which is made of a sliding door and closes the side opposite to the door pocket 2 of the entrance 1. The doors 4 are low-speed doors which are sliding doors and close the door pocket 2 side of the entrance 1.

Reference numeral 5 denotes an upper edge of the doorway 1 comprising a hanger case disposed horizontally above the doorway 1 and 6 denotes a high-speed door mounted on the upper edge 5 and arranged corresponding to the high-speed door 3. The low-speed rail 7 is a rail for a low-speed door mounted on the upper edge portion 5 and arranged corresponding to the low-speed door 4, and is provided between the upper edge portion 5 and the high-speed door rail 6. Reference numeral 8 denotes a high-speed door suspender that forms a part of the high-speed door 3 and is guided by the high-speed door rail 6 through the rolling wheels.

Reference numeral 9 denotes a part of the low-speed door 4 and a low-speed door hanger guided to the low-speed door rail 7 via a wheel.
Reference numeral 0 denotes a power transmission member, which is horizontally disposed in a longitudinal direction and is fixed to a suspender 9 of the low-speed door 4. 12 is pivoted. Reference numeral 13 denotes an endless power transmission strip made of a rope, which is wound around the door-closing guide wheel 11 and the door-opening guide wheel 12, and one side of which is held by the upper edge portion 5.

Numeral 15 denotes a connector, one side of which is fixed to the hanging handle 8 of the high-speed door 1 and holds the other side of the transmission strip 13 by the lower side, and protrudes upwardly across the longitudinal upper side of the transmission 10. The opposing portion 16 is formed. When both the high-speed door 3 and the low-speed door 4 are arranged at the fully closed position, the facing portion 16 faces and faces the intermediate peripheral surface of the transmission 10 of the door-closed-side guide wheel 11, and the two members are opposed to each other. When disposed at the fully open position, the facing portion 16 is mounted at a position facing and near the intermediate peripheral surface of the transmission 10 of the door opening side guide wheel 12.

In the elevator door apparatus constructed as described above, when the high-speed door 3 and the low-speed door 4 are fully closed, the high-speed door 3 closes the side of the doorway 2 opposite to the entrance 1, and the low-speed door 4 closes the door pocket of the entrance 1. The two sides are closed, and the state shown in FIG. Although not shown, the high-speed door 3 is driven by the door opening / closing means, and the entrance 1 is opened and closed by the high-speed door 3 and the low-speed door 4 through the operation of the high-speed door 3 as described later.

That is, when the high-speed door 3 is driven in the door opening direction in the state shown in FIG.
The transmission strip 13 is moved through. And transmission strip 1
3 is transmitted to the transmission 10 via the door-closed guide wheel 11 and the door-opened guide wheel 12. The operation of the transmission 10 causes the low-speed door 4 to move in the door opening direction at half the speed of the high-speed door 3 by the operation principle of the moving pulley, so that the entrance 1 is opened as shown in FIG. It has become. When the high-speed door 3 and the low-speed door 4 are fully closed, the locking device is used to lock the high-speed door 3 to the entrance / exit 1 edge, though not shown.

The transmission strip 13 is broken due to the action of an abnormal load on the transmission strip 13 or the wear of the transmission strip 13, or the transmission strip 13 is disengaged from the door-closing guide wheel 11 and the door-opening guide wheel 12. It is also conceivable that a problem such as deviation from the above occurs. In such a case, even if the high-speed door 3 is arranged at the predetermined fully-closed position and locked, the low-speed door 4 can be opened or prevented from being opened by the interlock 15 in order to prevent the low-speed door 4 from being opened. The effect is achieved.

That is, if the interlocking function of the high-speed door 3 and the low-speed door 4 is lost due to breakage of the transmission strip 13, etc.,
When the high-speed door 3 and the low-speed door 4 are arranged in the fully closed position,
The opposing portion 16 of the interlock 15 is the transmission 1 of the door-closed guide wheel 11
Since the high-speed door 3 is locked, the low-speed door 4 is prevented from moving in the door opening direction since the low-speed door 3 is locked.

When the high-speed door 3 and the low-speed door 4 are opening and closing, the high-speed door 3
When the interlocking function of the low-speed door 4 is lost, the interlock 1
5 is a door-closed guide wheel 11 and a door-opened guide wheel 12
The operation of the high-speed door 3 is transmitted to the low-speed door 4 on the peripheral surface of. For this reason, the low-speed door 4 is driven via the interlock 15, and the low-speed door 4 is arranged at a position corresponding to full closure or a position corresponding to full opening. Although not shown, the low-speed door 4 is manufactured so as to stop at the fully closed position shown in FIG. 1 and not to move further from this position in the door closing direction.

Further, at the time of an earthquake or the like, the power transmission strip 13 is broken, the door-closing guideway 11 and the door-opening guideway 12 deviate from each other, and at the same time, the suspender 8 moves along the entrance and exit of the entrance 1. Even if there is deformation due to tilting in the direction,
As shown in FIG. 3, the opposed portion 16 of the interlock 15 faces the peripheral surfaces of the door-closed guide wheel 11 and the door-opened guide wheel 12.

For this reason, the interlocking function of the high-speed door 3 and the low-speed door 4 is lost due to the breakage of the transmission strip 13 or the like, and the slanting hand 8 is deformed to be inclined in the direction along the entrance and exit of the entrance 1. Even so, the facing relationship between the facing portion 16 of the interlock 15 and the peripheral surface of the door-closed guide wheel 11 and the like is maintained. Therefore, even when the interlocking function of the high-speed door 3 and the low-speed door 4 is lost, and the hanging hand 8 is deformed in the direction along the entrance / exit direction of the doorway 1, the low-speed door 4 reacts to the movement of the high-speed door 3. Restraint is maintained.

For example, when the high-speed door 3 is locked, the low-speed door 4 is restrained at the normal door-closing position by the peripheral surface of the door-closing guide wheel 11 hitting the facing portion 16 of the interlock 15. Thereby, the movement of the low-speed door 4 in the door opening direction is prevented, so that the doorway 1 can be locked.

Further, when the high-speed door 3 and the low-speed door 4 are opening and closing, the high-speed door 3
In addition, when the interlocking function of the low-speed door 4 is lost, and when the hanging hand 8 is deformed to be inclined in the direction along the entrance and exit of the entrance 1, the opposing portion 16 of the interlock 15 is moved to the door-closed side guide wheel 11 and the door open side. The operation of the high-speed door 3 is transmitted to the low-speed door 4 by hitting the peripheral surface of the guide wheel 12. For this reason, the low-speed door 4 is driven via the interlock 15, and the low-speed door 4 is arranged at a position corresponding to a normal fully closed position or a position corresponding to a normal fully opened position.

Embodiment 2 FIG. FIG. 4 is a main part front view showing an example of another embodiment of the present invention. Except for FIG. 4, an elevator door device is configured in the same manner as in the above-described embodiment of FIGS. In the figures, FIGS.
The same reference numerals denote the corresponding parts, and the dimension C shown in FIG. 4 is the overlap dimension at the edges facing each other when the high-speed door 3 and the low-speed door 4 are arranged at the fully closed position, and is usually set to about 15 to 20 mm. Have been.

The dimension D shown in FIG. 4 is the transmission 10 of the door-closed guide wheel 11 when the high-speed door 3 is located at the fully closed position.

In addition, at both ends similar to the embodiment of FIGS. 1 to 3, a transmission 10 and a connector 15 to which a door-closed guide wheel 11 and a door-opened guide wheel 12 are pivotally mounted are arranged. Therefore, although detailed description is omitted, the same operation as the embodiment of FIGS. 1 to 3 can be obtained in the embodiment of FIG.

In the embodiment shown in FIG. 4, the overlapping dimension C at the edges facing each other when the high-speed door 3 and the low-speed door 4 are arranged in the fully closed position, and the high-speed door 3 is arranged in the fully closed position. The gap size D formed between the intermediate surface of the transmission 10 of the door-closed guide wheel 11 and the opposing portion 16 of the connector 15 is set to C> D.

When the high-speed door 3 and the low-speed door 4 are closing, the interlocking function of the high-speed door 3 and the low-speed door 4 is lost due to breakage of the transmission strip 13 and the like, and
When a deformation occurs in the direction in which the entrance 1 enters and exits, the opposing portion 16 of the interlock 15 hits the peripheral surface of the door-closing guide wheel 11, and the operation of the high-speed door 3 is transmitted to the low-speed door 4.

With the above configuration, when the high-speed door 3 and the low-speed door 4 are in the closing operation, the interlocking function of the high-speed door 3 and the low-speed door 4 is lost due to breakage of the transmission strip 13 and the like, and 8, when the low-speed door 4 is driven by the opposing portion 16 of the interlock 15 when the low-speed door 4 is driven by the opposing portion 16 of the interlocking member 15, when the high-speed door 3 is opposed to the low-speed door 4, There is no gap between the edges. Because
It is possible to prevent a problem caused by the generation of a gap between the low-speed door 4 and the high-speed door 3 that are driven and moved via the interlock 15.

When the high-speed door 3 is completely closed and locked, the interlocking function of the high-speed door 3 and the low-speed door 4 is lost due to breakage of the transmission strip 13 and the like, and the door 1 When deformation occurs that tilts in the direction along the entry and exit directions,
The movement of the low speed door 4 in the door opening direction with respect to the high speed door 3 is restricted. As a result, no gap is formed between the opposing edges of the high-speed door 3 and the low-speed door 4, so that a gap is generated between the low-speed door 4 and the high-speed door 3 in a state where the high-speed door 3 is locked. Problems can be prevented beforehand.

Embodiment 3 FIG. 5 is a view showing an example of another embodiment of the present invention, and is a main part front view showing a door open state. Except for FIG. 5, an elevator door device is configured similarly to the above-described embodiment of FIGS. In the drawings, the same reference numerals as those in FIGS. 1 to 3 denote corresponding parts, and the dimension E shown in FIG. 5 is from the edge of the entrance 1 of the high-speed door 3 when the high-speed door 3 and the low-speed door 4 are arranged at the open position. It is an overshoot dimension and is usually set to about 10 to 20 mm.

The dimension F shown in FIG. 5 corresponds to the peripheral surface of the door opening side guide wheel 12 near the middle of the transmission 10 when the high-speed door 3 is further moved from the open position by the dimension E, and the facing portion of the connector 15. 16 and the oversize E

Also in the elevator door apparatus constructed as described above, the entrance 1 is opened and closed by the operation of the high-speed door 3 and the low-speed door 4 similar to the embodiment of FIGS. In addition, at both ends similar to the embodiment of FIGS. 1 to 3, a transmission 10 and a connector 15 to which a door-closed guide wheel 11 and a door-opened guide wheel 12 are pivotally mounted are arranged. Therefore, although detailed description is omitted, the same operation as the embodiment of FIGS. 1 to 3 can be obtained in the embodiment of FIG.

In the embodiment shown in FIG. 5, when the high-speed door 3 is further moved from the fully open position of the entrance 1 and is arranged at the position of the oversize E, the transmission 10 of the door-opening side guide wheel 12 is moved. A gap size F formed between the intermediate peripheral surface and the facing portion 16 of the connector 15 is set to F <E.

For this reason, when the high-speed door 3 and the low-speed door 4 are in the opening operation, the interlocking function of the high-speed door 3 and the low-speed door 4 is lost due to the breakage of the transmission strip 13 and the like, and When a deformation that tilts in a direction along the entrance / exit direction of the entrance / exit 1 occurs, the opposing portion 16 of the interlock 15 is moved to the door opening side guide wheel 12.
The operation of the high-speed door 3 is transmitted to the low-speed door 4 on the peripheral surface of.

Then, in a state where the high-speed door 3 is disposed at the position of the excessive dimension E from the edge of the entrance 1, the low-speed door 4
Is not restricted, and the low-speed door 4 does not protrude from the edge of the entrance 1 in the door closing direction. Therefore, the interlocking function of the high-speed door 3 and the low-speed door 4 is lost, and the hanging hand 8 is deformed to be inclined in the direction along the entrance / exit 1 of the entrance / exit 1, and the low-speed door 4 is more than the entrance / exit 1 edge. Problems caused by protruding in the door closing direction can be prevented beforehand.

And the peripheral surface of the door-closed guide vehicle or the like is opposed to each other. Therefore, even when the interlocking function of the high-speed door and the low-speed door is lost, and the hanging hand is deformed in the direction along the entrance direction of the entrance, the restraint of the low-speed door against the movement of the high-speed door is maintained. In addition, there is an effect of preventing a problem caused by moving only the low-speed door regardless of the movement of the high-speed door.

Further, when the high-speed door is located at the fully closed position, a gap dimension formed between the door-closed guide wheel and the connector is:
When both the high-speed door and the low-speed door are arranged in the fully closed position, the overlap size is set to be smaller than the overlap size at the mutually opposing edges. For this reason, the interlocking function of the high-speed door and the low-speed door is lost due to the breakage of the transmission strip, etc., and the hanging hand is deformed to tilt in the direction along the entrance and exit, and the high-speed door is fully closed. In the locked state, the movement of the low-speed door in the door opening direction with respect to the high-speed door is restricted to a range in which no gap is formed between the opposed edges. Therefore, there is an effect of preventing a problem caused by the generation of a gap between the high-speed door and the high-speed door in a locked state.

Further, as described above, according to the present invention, when the high-speed door is further moved beyond the predetermined distance by a predetermined distance from the open position, the gap between the peripheral surface of the door-opening guide vehicle near the transmission intermediate and the opposing portion of the connector. Is set to be smaller than the predetermined oversize dimension of the high-speed door.

Accordingly, even if the interlocking function of the high-speed door and the low-speed door is lost due to the breakage of the transmission strip or the like, and even if the hanging hand is deformed to be inclined in the direction along the entrance and exit, the interlocking element can be used. And the peripheral surface of the door-closed guide vehicle or the like is opposed to each other. Therefore, even when the interlocking function of the high-speed door and the low-speed door is lost, and the hanging hand is deformed in the direction along the entrance and exit direction, the restraint of the low-speed door against the movement of the high-speed door is maintained. In addition, there is an effect of preventing a problem caused by moving only the low-speed door regardless of the movement of the high-speed door.

Further, when the high-speed door further moves beyond the predetermined distance from the open position by a predetermined distance, a gap formed between the door-opening guide wheel and the connector is set to be smaller than the predetermined over-size of the high-speed door.
