In an elevator, a car is connected to one end of a hoist rope, the other end of which is connected with a counterweight, and the hoist rope is wound around a traction machine. The elevator car is moved up and down in the hoistway by frictionally driving the hoisting ropes with the hoisting machine.

Fig. 4 shows an example of the car 6 of an elevator to which the elevator door of the present invention is applied (the specific structure of the elevator door is omitted in fig. 4).

The elevator car door is used for opening and closing an access of a car of the elevator. The elevator door 1 of the present invention can be used for various cars. For example, the present invention may be applied to a car having two elevator doors as shown in fig. 4, or may be applied to a car having 3 or 4 or more elevator doors. The elevator car door 1 can be used for a center opening door car door system and can also be used for a side opening door car door system.

Fig. 1 shows an example of an elevator door 1 according to the present invention, fig. 2 is a sectional view taken along line a-a of fig. 1, and fig. 3 is a partially enlarged view of fig. 2. Fig. 1 is a schematic external view of the elevator car door 1 shown in fig. 4, as viewed from the front. The elevator door 1, after being mounted to the car, has an outer surface facing the hoistway as shown, and an inner surface on the opposite side of the outer surface as viewed by passengers in the car. In the following description, a direction toward the inside of the car will be described as an inner side (+ Z direction) and a direction opposite thereto will be described as an outer side (-Z direction). In the following description, one side in the door closing direction is referred to as a door stop side (+ X direction) and one side in the door opening direction is referred to as a door pocket side (-X direction).

As shown in the figure, the elevator car door 1 includes a door panel 2 and a reinforcement 3.

First, the door panel 2 will be explained. The door panel 2 includes a main body 20, a door stop side end 21, a door pocket side end 22, an upper side end 23, and a lower side end 24.

The door panel 2 is made of, for example, a common steel plate or a stainless steel plate. For example, four end portions of a single common steel plate or stainless steel plate are bent to form four end portions of the door stop side end portion 21, the door pocket side end portion 22, the upper side end portion 23, and the lower side end portion 24, and the main body portion 20 is formed by an intermediate portion between these end portions. The door stop side end 21, the door pocket side end 22, the upper side end 23 and the lower side end 24 are respectively formed at right angles to the main body 20, and each has an L-shaped cross section including a side and a folded edge.

Here, the door stop side end 21 will be described as an example. As shown in fig. 2 and 3, the door stop side end portion 21 forms a right angle with the main body portion 20, and the door stop side end portion 21 has an L-shaped cross section and forms an internal space D with the main body portion 20. That is, the door stop side end portion 21 includes a side 211 that forms a right angle with the main body portion 20 and a folded edge 212 that forms a right angle with the side 211, and an internal space D is formed by the main body portion 20, the side 211, and the folded edge 212.

Next, the reinforcing material 3 will be explained. As shown in fig. 1, the reinforcement 3 is provided on the door stop side of the door panel 2. The reinforcing material 3 of the present invention is not only a member for improving the strength of the elevator car door 1, but also an attachment member for attaching a safety device.

The reinforcement 3 includes a flat plate portion 31 in a flat plate shape and a mounting portion 32 for mounting the safety device. The flat plate portion 31 extends along the longitudinal direction of the door panel 2. The attachment portion 32 is adjacent to the flat plate portion 31, is positioned on the door stop side of the flat plate portion 31, and extends in the longitudinal direction of the door panel 2.

The flat plate portion 31 is fixed to the main body portion 20 by adhesion, for example, and the mounting portion 32 is fixed (e.g., riveted, screwed, etc.) to the door stop side end portion 21 of the door panel 2 by a fastener (not shown). Thereby, the reinforcement 3 is fixed to the door panel 2.

The width (horizontal width) of the attachment portion 32 is larger than the width of the flat plate portion 31. The width of the mounting portion 32 is set in accordance with the width (width in the horizontal direction) of a safety device described later. The width (width in the horizontal direction) of the reinforcement 3 as a whole is, for example, 0.4 to 0.6 times the width (width in the horizontal direction) of the door panel 2.

As shown in fig. 2 and 3, the attachment portion 32 protrudes outward from the flat plate portion 31, and the attachment portion 32 includes a door stop side corner E and a door pocket side corner F, and the door stop side corner E is housed in the internal space D of the door panel 2.

More specifically, the mounting portion 32 includes a connecting portion 321, a plateau portion 322, and a side plate portion 323. The connecting portion 321 forms a right angle with the flat plate portion 31, and connects the end portion of the flat plate portion 31 on the door stop side and the end portion of the high platform portion 322 on the door pocket side. The high portion 322 is perpendicular to the connecting portion 321 and parallel to the flat plate portion 31. Side plate portion 323 is perpendicular to plateau portion 322 and parallel to connecting portion 321. The width (horizontal width) of the high portion 322 is larger than the width (front-rear width) of the connecting portion 321 and larger than the width (front-rear width) of the side plate portion 323.

The plateau 322 and the main body 20 are parallel to each other. Since the projecting height G of the attachment portion 32 from the main body portion 20 to the outside (i.e., the predetermined distance G between the outer surface of the stepped portion 322 and the outer surface of the main body portion 20) is smaller than the height H of the internal space D of the door panel 2 (i.e., the predetermined distance H between the inner surface of the folded edge 212 of the door stop side end portion 21 and the outer surface of the main body portion 20), the door stop side corner portion E of the attachment portion 32 can enter the internal space D formed by the main body portion 20 and the door stop side end portion 21, and the end portion of the stepped portion 322 on the door stop side is positioned inside the folded edge 212 and overlaps the folded edge 212 in the front-rear direction.

The side plate portions 323 are parallel to the side edges 211 of the door stop side end portion 21. The width of the side plate 323 is smaller than the width of the side 211, and the side plate 323 is accommodated in the internal space D of the door panel 2 and horizontally overlaps the folded edge 212.

The reinforcement 3 of the present invention is provided on the door stop side of the door panel 2, and includes the flat plate portion 31 extending in the longitudinal direction of the door panel 2 and the mounting portion 32 adjacent to the flat plate portion 31, the mounting portion 32 protruding outward from the flat plate portion 31, and the door stop side corner portion E of the mounting portion 32 being housed in the internal space D of the door panel 2, so that the strength of the elevator car door 1 can be improved.

Here, the mounting portion 32 includes a connecting portion 321 that forms a right angle with the flat plate portion 31, a high portion 322 that forms a right angle with the connecting portion 321 and is parallel to the flat plate portion 321, and a side plate portion 323 that forms a right angle with the high portion 322, and the door stop side corner portion E formed between the high portion 322 and the side plate portion 323 is accommodated in the internal space D of the door panel 2, and can support the door stop side end portion 21, and this configuration can more effectively improve the strength of the elevator car door 1.

As shown in fig. 1, it may be provided that the upper end of the reinforcement 3 protrudes into the internal space formed between the upper end 23 of the door panel 2 and the main body 20, and/or the lower end of the reinforcement 3 protrudes into the internal space formed between the lower end 24 of the door panel 2 and the main body 20, which may further improve the strength of the elevator car door 1.

Of course, the length of the reinforcement 3 may be smaller than the distance between the lower end of the upper end 23 and the upper end of the lower end 24. That is, the upper end of the reinforcement 3 may be spaced apart from the lower end of the upper end 23 by a predetermined distance, and the lower end of the reinforcement 3 may be spaced apart from the upper end of the lower end 24 by a predetermined distance.

The lengths of the flat plate portion 31 and the mounting portion 32 may be equal, or the length of the flat plate portion 31 may be smaller than the length of the mounting portion 32.

The reinforcement 3 is made of, for example, a common steel plate or a stainless steel plate. For example, the reinforcing member 3 is formed by bending a single ordinary steel plate or stainless steel plate. Preferably, the thickness (plate thickness) of the reinforcement 3 is substantially equal to the thickness (plate thickness) of the door panel 2.

Next, a safety device to which the reinforcing material 3 is attached will be described. The safety device arranged on the elevator car door is a mechanical safety device and a photoelectric safety device. In the present invention, as shown in fig. 1, the first safety device 4 is a mechanical safety device such as a safety touch panel. The first safety device 4 includes two sets of upper and lower mounting assemblies 42 and a detection switch (not shown) in addition to the contact portion 41. The upper and lower mounting assemblies 42 respectively have a mounting seat 421 and a link 422 rotatably connecting the contact portion 41 to the mounting seat 421. The detection switch is provided on a lower mounting seat 421, the wire 43 is connected to the detection switch, and the other end of the wire 43 is connected to a car roof junction box (not shown) above the car 6.

The second safety device 5 is an electro-optical safety device such as a multi-beam door sensor. The second safety device 5 includes a light-emitting portion and a light-receiving portion, and in the center-opening door system, the light-emitting portion and the light-receiving portion are respectively attached to a pair of elevator doors 1 provided to face each other, while in the side-opening door system, one of the light-emitting portion and the light-receiving portion is attached to the elevator door 1, and the other is attached to a pillar or the like on the door stop side.

In the elevator door 1 of the present invention, both the first safety device 4 and the second safety device 5 are mounted to the mounting portion 32 of the reinforcement 3.

Specifically, as shown in fig. 2 and 3, the mounting portion 32 protrudes outward from the flat plate portion 31, and the height portion 322 of the mounting portion 32 is spaced apart from the main body portion 20 of the door panel 2 by a predetermined distance G, so that the mounting seat 421 can be fixed to the mounting portion 32 with a fastener (e.g., a bolt, a nut, etc.) without interfering with the main body portion 20. The mount 421 is attached to the boss side of the high table portion 322 of the mounting portion 32.

The light projecting portion or the light receiving portion of the second safety device 5 is attached to the door shield side of the high table portion 322 of the attachment portion 32 using a fastener (a screw, a bolt, or the like).

The height 322 of the mounting portion 32 is longer than at least the distance between the upper end of the upper mounting seat 421 and the lower end of the lower mounting seat 421. The width of the step-up portion 322 of the mounting portion 32 is at least larger than the sum of the widths of the mounting seat 421 and the light projecting portion or the light receiving portion of the second safety device 5.

Preferably, the reinforcement 3 further includes a plurality of wire fixing portions 33 for fixing the wires 43 of the first safety device 4 (e.g., a safety contact). The wiring fixing portion 33 is provided at the door pocket side corner portion F of the mounting portion 32. The wiring fixing portion 33 is formed by providing one through hole in each of the connecting portion 321 side and the high table portion 322 side of the door pocket side corner portion F, and inserting a tie (binding tape) into the two through holes.

The wiring 43 of the first safety device 4 needs to be pulled from the mounting seat 421 below the elevator car door 1 to the car roof junction box (not shown) above the car 6, and the wiring 43 can be easily fixed at a short distance by providing the wiring fixing portion 33 at the jacket-side corner F of the mounting portion 32 of the reinforcement 3.

As described above, the reinforcing member 3 of the present invention can not only enhance the strength of the elevator door 1 and mount various safety devices that need to be installed in the elevator door 1, but also easily fix the wiring of the safety devices.
