[0017] Embodiments are described with reference to the drawings. In addition, like or equivalent parts are denoted by like reference numerals in each drawing. Repetitive description of such parts is appropriately simplified or omitted.

[0018] Embodiment 1

[0019] Figure 1 is a front view of a key part of a control device of an elevator in Embodiment 1. Figure 2 is a side view of a key part of a control device of an elevator in Embodiment 1.

[0020] In Figure 1 and Figure 2 , the control device is provided in a non-illustrated machine room or hoistway of an elevator. The control device is provided so as to be able to perform overall control of the elevator. The control device has a housing 1, a mounting body 2, a pair of suppression bodies 3, a box body 4, an electromagnetic switch 5, a traction body 6, and an adjustment body 7.

[0021] The housing 1 constitutes the outer contour of the control device. For example, the housing 1 is formed in a box shape. The box body 4 has a beam 1a. The beam 1a is disposed in the interior of the housing 1 and at the upper portion with the length direction as the horizontal direction.

[0022] The mounting body 2 is provided in the interior of the housing 1 and at the lower portion. For example, the mounting body 2 is formed in a plate shape.

[0023] For example, the pair of suppression bodies 3 are each a vibration isolation rubber. The pair of suppression bodies 3 are arranged in the horizontal direction and mounted to the upper surface of the mounting body 2.

[0024] The box body 4 is mounted to the upper surface of the pair of suppression bodies 3. The box body 4 is supported by the pair of suppression bodies 3. The box body 4 is an acoustic insulation specification. For example, the box body 4 is provided so as to be able to insulate sound in an acoustic foam.

[0025] For example, the electromagnetic switch 5 is an electromagnetic contactor. For example, the electromagnetic switch 5 is an electromagnetic relay. The electromagnetic switch 5 is housed in the box body 4. The electromagnetic switch 5 is provided so as to be able to supply electric power to the motor of a non-illustrated traction machine in accordance with an instruction from a non-illustrated control section. The electromagnetic switch 5 is supported by the mounting body 2 via the box body 4 and the pair of suppression bodies 3.

[0026] For example, the traction body 6 is a wire. The traction body 6 has stretchability. The traction body 6 is provided so as to be able to apply a load in a direction in which the electromagnetic switch 5 is pulled up via the box body 4. Specifically, the traction body 6 is hung on the beam 1a. One end of the traction body 6 is connected to the box body 4 on the side on which the electromagnetic switch 5 is located. The other side of the traction body 6 is connected to one of a plurality of connection points that are set in advance in the interior of the housing 1.

[0027] For example, the adjustment body 7 is a handle. The adjustment body 7 is provided on the other side of the traction body 6. The adjustment body 7 is provided so as to be able to adjust the tension of the traction body 6. For example, in the case where the adjustment body 7 is a handle, the tension of the traction body 6 is adjusted by turning the handle.

[0028] According to the above-described embodiment 1, the traction body 6 applies a load in the direction in which the electromagnetic shutter 5 is pulled up via the box body 4. Therefore, it is possible to disperse the transmission of the solid-borne sound at the time of opening and closing of the electromagnetic shutter 5. As a result, it is possible to suppress the solid-borne sound at the time of opening and closing of the electromagnetic shutter 5. For example, in a hotel, in the case where a machine room is provided in an intermediate floor, it is possible to suppress the solid-borne sound toward a guest room of the intermediate floor.

[0029] Further, the other end of the traction body 6 is linked to one of the plurality of link points inside the casing 1. Therefore, it is possible to appropriately suppress the solid-borne sound at the time of opening and closing of the electromagnetic shutter 5 in accordance with the setting conditions of the control device on site. For example, in the case where a beam on the building side exists directly below the electromagnetic shutter 5, by linking the other end of the traction body 6 to a link point away from the beam, it is possible to suppress the solid-borne sound toward the building side.

[0030] Further, the traction body 6 has a stretchability. Therefore, even in the case where vibrations caused by the opening and closing of the electromagnetic shutter 5 are dispersed to propagate as solid-borne sound, it is possible to suppress these solid-borne sounds. For example, it is possible to absorb vibrations in the upward direction caused by the opening and closing of the motor.

[0031] Further, the adjustment body 7 adjusts the tension of the traction body 6. Therefore, it is possible to reduce the load of work when changing the proportion of dispersing vibrations caused by the opening and closing of the electromagnetic shutter 5 on site.

[0032] Further, the electromagnetic shutter 5 is housed in the box body 4. The box body 4 is supported by the pair of suppression bodies 3. In this state, the pair of suppression bodies 3 suppresses vibrations at the time of opening and closing of the electromagnetic shutter 5. Therefore, it is possible to more reliably suppress the solid-borne sound at the time of opening and closing of the electromagnetic shutter 5.

[0033] In addition, the box body 4 directly suppresses sound at the time of opening and closing of the electromagnetic shutter 5. Therefore, it is possible to more reliably suppress the sound at the time of opening and closing of the electromagnetic shutter 5.

[0034] Embodiment 2

[0035] Figure 3 is a front view of a control device of an elevator in Embodiment 2. In addition, the same reference numerals are attached to parts that are the same as or equivalent to those of Embodiment 1. The description of the parts is omitted.

[0036] In Figure 3In the present embodiment, a beam 8 of the building is provided in a machine room or a hoistway, not shown. The beam 8 is arranged with the longitudinal direction as the horizontal direction.

[0037] A frame 1b is provided in the lower portion of the casing 1. The frame 1b is arranged in the vicinity of the beam 8. Specifically, one edge portion of the frame 1b is arranged directly above the beam 8. One edge portion of the frame 1b is supported to the beam 8.

[0038] A pair of suppression bodies 3 is attached to the upper surface of the frame 1b.

[0039] Although not shown in detail, the other side of the traction body 6 is branched in a manner that a plurality of end portions are present. The plurality of end portions are linked to a plurality of link points that are set in advance in the inside of the casing 1.

[0040] According to the above-described embodiment 2, at the other side of the traction body 6, the plurality of end portions are linked to the plurality of link points that are set in advance in the inside of the casing 1. Therefore, it is possible to disperse the solid propagation of the vibration caused by the opening and closing of the electromagnetic switch 5.

[0041] In addition, according to the building, there are the beam 8 in which the vibration caused by the opening and closing of the electromagnetic switch 5 easily performs solid propagation and the beam 8 in which the vibration caused by the opening and closing of the electromagnetic switch 5 hardly performs solid propagation. In this case, according to the setting condition of the control device on site, it is sufficient to appropriately suppress the solid propagation sound at the time of opening and closing of the electromagnetic switch 5 by changing the link points of the other side of the traction body 6.

[0043] Figure 4 is a front view of a control device of an elevator in the embodiment 3. In addition, the same reference numerals are attached to the portions that are the same as or equivalent to those of the embodiment 1. The description of the portions is omitted.

[0044] As shown in Figure 4 , a pulley 9 is provided above the box body 4. The traction body 6 is wound around the pulley 9.

[0045] According to the above-described embodiment 3, the traction body 6 is wound around the pulley 9. At this time, the pulley 9 becomes a fulcrum at the time of applying a load in the direction of pulling up the electromagnetic switch 5. Therefore, it is possible to reduce the load of the work at the time of changing the proportion of dispersing the vibration caused by the opening and closing of the electromagnetic switch 5 on site.
