Japanese Utility Model Publication No. 5-69048

  In the technique described in Patent Document 1, although a foreign object can be prevented from falling into the hoistway when a passenger gets on and off the car, a step is generated between the both sills and both movable members. When a car such as a car gets on and off the car, there is a problem that the step becomes an obstacle to prevent a smooth boarding and getting off.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide an elevator sill gap closing device capable of smoothly getting on and off the car.

According to the first aspect of the present invention, at least one of the elevator car side sill and the landing side sill is provided with a fixing member for guiding the entrance door, and a front end of the fixing member along the door opening / closing direction. A movable member that is slidable in the front-rear direction approaching / separating from the other threshold, and the movable member slides forward in conjunction with the door opening operation of the doorway, and the car is opened when the doorway is opened. Assuming that the gap between the side sill and the landing side sill is a device for closing the gap between the sills of the elevator, the tread of the movable member is superimposed on the tread of the fixed member when the doorway is fully closed. together are, each tread is inclined forwardly downwardly of the fixed member and the movable member, the movable member has adapted to slide along the tread of the fixing member when the door-opening operation It is characterized in that.

Therefore, in at least the invention according to claim 1, for example, the tread surface of the fixed member that passes before a vehicle such as a wheelchair or a carriage rises the step between the fixed member and the movable member has a downward slope. It becomes possible to easily climb the steps.

Further, by being inclined forwardly downward even tread of the movable member, since the tread of the movable member to pass after climbing the step is inclined downward, again fall to the level difference after climbing the steps Can be prevented.

Preferably , as described in claim 2, when a shock absorber is attached to the front end of the movable member along the door opening / closing direction, and the shock absorber is abutted against the other sill when the doorway is opened, It becomes possible to more reliably close the gap between the both sides on the side and the landing side.

Specifically, as described in claim 3, the movable member includes a cam portion that engages with the entrance door when the door is opened and closed, and the urging means that constantly urges the movable member rearward is the movable member. It is interposed between the fixed member and the movable door slides forward against the urging force of the urging means when the door is pressed against the cam when the door is opened. If the movable member is pulled back by the biasing force of the biasing means, the movable member slides in conjunction with the door opening / closing operation of the doorway.

According to the first aspect of the present invention, for example, a vehicle such as a wheelchair or a carriage can easily climb the step between the fixed member and the movable member, so that the car can be easily put in and out of the car. There is an advantage that can be done. Further, since the tread surface of the movable member is also inclined forward and downward, it is prevented from falling again to the step after getting over the step, and the car can be boarded and exited more smoothly.

  FIG. 1 is a diagram showing a more specific embodiment of the present invention, and is a diagram showing an outline of both the entrance and exit on the car side and the landing side.

  As shown in FIG. 1, a car side sill 2 is arranged along the door opening / closing direction at the lower edge of the car side doorway 1 formed in the elevator car, and the car side sill 2 is the car side doorway 1. The guide shoe 3a of the car side door 3 which is the doorway for opening and closing the door is guided. On the other hand, a landing-side sill 5 is arranged at the lower edge of the landing-side entrance 4 formed in the landing so as to face the car-side sill 2, and the landing-side sill 5 opens and closes the landing-side entrance 4. The guide shoe 6a of the door 6 is guided. The landing side sill 5 and the car side sill 2 are fixed with brackets 7 respectively.

  An engagement plate 8 is provided on the back surface side of the landing side door 6, and an engagement block 9 having a substantially U-shaped cross section capable of receiving the engagement plate 8 is provided on the back surface side of the car side door 3. ing. Each of the engagement plate 8 and the engagement block 9 is attached along the traveling direction of the car. When the car is landed on the landing, the engagement plate 8 is received by the engagement block 9 and the both engage with each other. Thus, the car-side door 3 and the landing-side door 6 are interlocked, and the doors 3 and 6 open and close the doors 1 and 4 with the driving force of the door driving device 10 provided in the car.

  Here, between the car-side sill 2 and the landing-side sill 5, in order to avoid interference between the landing-side sill 5 and the engagement block 9 and between the car-side sill 2 and the engagement plate 8 when the car is running. In addition, a predetermined gap G is provided as a so-called running clearance.

  FIG. 2 is a perspective view showing an outline of the door opening direction side end of the car side sill 2 and the landing side sill 5.

  As shown in FIG. 2, the car-side sill 2 includes a fixed member 11 in which a sill groove 12 for guiding the car-side door 3 is formed, and a movable member 14 provided at the front end of the fixed member 11 along the door opening / closing direction. The movable member 14 is slidable in the forward direction approaching the landing side sill 5 and in the rear direction separating from the landing side sill 5.

  3 is a cross-sectional view taken along the line AA in FIG. 2. FIG. 3A shows a state where the movable member 14 is located rearward, and FIG. 3B shows the state where the movable member 14 is located forward. It is a figure which shows a state.

  Specifically, as shown in FIG. 3A in addition to FIG. 2, the fixing member 11 has a protruding portion 13 formed on the front side of the sill groove 12, and a door is formed on the front end surface of the protruding portion 13. A groove 13a is formed along the opening and closing direction.

  On the other hand, the movable member 14 has a substantially E-shaped cross section, and the movable member 14 is fitted to the protruding portion 13 of the fixed member 11. That is, the intermediate rib 15 of the movable member 14 is fitted in the groove 13 a of the protruding portion 13, and the tread surface 16 a of the upper wall portion 16 of the movable member 14 is superimposed on the tread surface 13 b of the protruding portion 13. On the other hand, the lower wall portion 17 of the movable member 14 is superposed below the protruding portion 13.

  The tread surface 16 a of the movable member 14 is inclined forward and downward, and the tread surface 13 b of the fixed member 11 is further inclined forward and downward with respect to the tread surface 16 a of the movable member 14. That is, the upper wall portion 16 is formed in a tapered shape that becomes thinner toward the tip thereof. In addition, the groove part 13a of the protrusion part 13 and the lower surface of the protrusion part 13 are also formed so as to incline forward and downward like the tread surface 13b of the fixing member 11.

  The protruding portion 13 is formed with an insertion hole 13 c penetrating between the groove portion 13 a and the sill groove 12, and the cam portion 15 a that passes through the insertion hole 13 c and protrudes into the sill groove 12 is the tip of the intermediate rib 15. Projected from. The door closing direction side end surface 15b of the cam portion 15a is inclined rearward in the door opening direction, and the car side door 3 engages with the door closing direction side end surface 15b of the cam portion 15a through the guide shoe 3a during the door opening operation. Then, as shown in FIG. 3B, the movable member 14 slides forward along the tread surface 13 b of the fixed member 11.

  Here, in a state where the movable member 14 is positioned forward, that is, in an entrance / exit open state, a slight step is generated between the tread surface 13b of the fixed member 11 and the tread surface 16a of the movable member 14 that overlap each other.

  Further, the movable member 14 and the fixed member 11 are connected by a return spring 18 that is an urging means, and the movable member 14 is constantly urged rearward.

  Further, a shock absorber 19 formed of a rubber-based elastic material is attached to the upper end surface of the movable member 14 along the door opening / closing direction, and the movable member 14 is in contact with the front end of the landing side sill 5. It is designed to reduce the impact and prevent the generation of abnormal noise.

Therefore, in this embodiment, when the car reaches the landing and opens the door, the car-side door 3 presses the cam portion 15a of the movable member 14 via the guide shoe 3a, so that the biasing force of the return spring 18 is increased. The movable member 14 slides forward along the tread 13b of the fixed member 11 against this, and the shock absorber 19 hits the tip of the landing side sill 5 to close the gap G.

  At this time, for example, when the stroke amount of the movable member 14 is larger than the gap G due to an installation error or the like, the buffer body 19 is elastically deformed to absorb the error.

  When the door is closed, the engagement between the guide shoe 3a and the cam portion 15a is released, and the movable member 14 is pulled back by the urging force of the return spring 18.

  That is, according to the present embodiment, since the upper wall portion 16 of the movable member 14 is formed in a tapered shape that becomes thinner toward the tip, the tread surface 13b of the fixed member 11 and the movable member 14 when the doorway is opened. In addition, the step surface 13b of the fixing member 11 that passes before the vehicle gets over the step when the vehicle such as a carriage or a wheelchair gets off the car has a downward slope. Thus, it is possible to easily get over the step, and to smoothly get on and off the car.

  Further, since the tread 16a of the movable member 14 is inclined forward and downward, it is prevented from falling again to the step after overcoming the step, so that the car can be boarded / exited more smoothly. There are benefits.

  Furthermore, since the shock absorber 19 attached to the front end surface of the movable member 14 hits the landing side sill 5 when the doorway is opened, the shock absorber 19 is elastically deformed even if the gaps G on the floors are different due to installation errors, for example. In addition, there is a merit that the error can be absorbed, and there is a merit that an abnormal noise can be prevented when the tip of the movable member 14 hits the landing side sill 5.

  In the present embodiment, the car side sill 2 is composed of the fixed member 11 and the movable member 14, but the landing side sill 5 may be composed of the fixed member 11 and the movable member 14. Needless to say, it is of course possible to configure both the car side sill 2 and the landing side sill 5 with a fixed member 11 and a movable member 14.

It is a figure which shows embodiment of this invention, Comprising: The schematic which shows both the entrances and exits of a cage | basket side and a landing side. The perspective view which shows the outline of both the sills of the car side in FIG. 1, and the landing side.
