Brief Description of the Drawings

[0008] [Figure 1] This is a schematic partial cross-sectional view showing the internal structure of an elevator according to Embodiment 1. [Figure 2] This is a schematic partial perspective view of the rope cover according to Embodiment 1. [Figure 3] This is a schematic cross-sectional view of the rope cover according to Embodiment 2. [Figure 4] This is a schematic cross-sectional view of a modified example of the rope cover according to Embodiment 2. [Modes for carrying out the invention]

[0009] Embodiments of the present disclosure will be described below. Unless otherwise specified, the same or corresponding parts in the following drawings will be given the same reference numerals, and their descriptions will not be repeated.

[0010] Embodiment 1. <Elevator Configuration> Figure 1 is a schematic partial cross-sectional view showing the internal structure of an elevator according to Embodiment 1. The elevator shown in Figure 1 comprises a hoistway 100 and a machine room 200. Inside the hoistway 100, for example, a car in which people ride and a rope 11 for lowering the car are arranged (not shown). The car moves up and down in the vertical direction inside the hoistway 100.

[0011] As shown in Figure 1, the machine room 200 is located above the hoistway 100. Inside the machine room 200 are a hoisting machine (not shown) and a rope cover 2. The hoisting machine raises or lowers the rope 11, thereby raising or lowering the elevator car.

[0012] The elevator uses a two-to-one roped drive system. Therefore, as shown in Figure 1, the rope 11 extends from the hoistway 100 towards the machine room 200.

[0013] A rope end portion 12 is attached to the end of the rope 11. The rope end portion 12 includes, for example, a socket and a babbitt. The end of the rope 11 is inserted through the opening of the socket. The inside of the socket is filled with babbitt. The heated babbitt cools inside the socket, causing it to solidify. As the babbitt solidifies inside the socket, the end of the rope 11 is fixed inside the socket. In this way, the rope end portion 12 is attached to the end of the rope 11.

[0014] Multiple rope ends 12 are exposed to the machine room 200. Specifically, the large opening of the socket faces upward, and the small opening of the socket faces downward. The small opening of the socket is not exposed to the machine room 200. The large opening of the socket is exposed to the machine room.

[0015] A steel bar 13 is connected to each of the multiple rope end sections 12. Each of the multiple steel bars 13 extends from the floor GR of the machine room 200 towards the ceiling. As the elevator moves up and down, vibrations from the rope 11 are transmitted to the steel bars. To prevent the vibration noise transmitted to the steel bars from leaking out, the rope cover 2 is installed on the floor GR of the machine room 200 so as to cover the rope end sections 12 and the steel bars 13. As shown in Figure 2, a portion of the rope cover 2 may be embedded in the floor GR of the machine room 200.

[0016] <Rope cover configuration> Figure 2 is a schematic partial perspective view of the rope cover 2 according to Embodiment 1. The rope cover 2 includes a side wall 21, a sound-absorbing member 22, and a bottom wall 23. As shown in Figure 2, the side wall 21 covers the rope end portion 12 and the iron bar 13. The side wall 21 is connected to the bottom wall 23. The rope end portion 12 is provided on the bottom wall 23. From a different viewpoint, a portion of the rope end portion 12 is exposed from the bottom wall 23, and a portion of the rope end portion 12 is located inside the bottom wall 23.

[0017] The sound-absorbing member 22 is positioned on the inner circumferential surface of the side wall 21. The sound-absorbing member 22 absorbs vibrational sound transmitted to the iron rod.

[0018] The rope terminal part 12 needs to be inspected regularly. If the rope cover 2 is installed on the floor GR of the machine room 200 so as to cover the rope terminal part 12 and the iron bar 13 for sound insulation, it will be difficult to inspect the rope terminal part 12.

[0019] Here, the feature of the rope cover 2 according to the first embodiment is that, as shown in FIGS. 1 and 2, an opening 24 is provided in the side wall 21. By doing so, the inspector can check the rope terminal part 12 from the opening 24. Therefore, the rope terminal part 12 can be easily inspected.

[0020] The opening 24 is arranged at 50 mm or more from the floor GR of the machine room 200. From a different perspective, as shown in FIGS. 1 and 2, the distance H from the floor GR to the lower end of the opening 24 is 50 mm or more. In this way, the inspector can easily check the rope terminal part 12.

[0021] The opening 24 is arranged at 500 mm or less from the floor GR of the machine room 200. From a different perspective, as shown in FIGS. 1 and 2, the distance H from the floor GR to the lower end of the opening 24 is 500 mm or less. In this way, the inspector can easily check the rope terminal part 12.

[0022] The side wall 21 may have four surfaces. The opening 24 is formed so as to straddle two of the four surfaces. In this way, even if a plurality of rope terminal parts 12 are arranged inside the rope cover 2, the inspector can check the rope terminal part 12 away from the opening 24. That is, the inspector can check all of the plurality of rope terminal parts 12 arranged inside the rope cover 2.

[0023] <Function and effect> The rope cover 2 according to this disclosure is installed on the floor surface GR of the elevator machine room 200. The rope cover 2 covers the rope end portion 12. The rope cover 2 includes side walls 21. The side walls 21 surround the rope end portion 12. An opening 24 is provided in the side walls 21.

[0024] This allows the inspector to easily check the rope end portion 12. According to the rope cover 2 described above, the opening 24 is positioned at least 50 mm from the floor surface GR.

[0025] This allows the inspector to easily check the rope end portion 12. According to the rope cover 2 above, the elevator uses a two-to-one roping system.

[0026] In this way, an inspector can easily check the rope end portion 12 inside the machine room where the rope cover 2 is located.

[0027] Embodiment 2. <Rope cover configuration> Figure 3 is a schematic cross-sectional view of the rope cover 2 according to Embodiment 2. The rope cover 2 shown in Figure 3 basically has the same configuration as the rope cover 2 shown in Figures 1 and 2 and can achieve the same effect, but differs in that it is equipped with an opening / closing mechanism 4. Figure 3 shows the opening 24 opened by the opening / closing mechanism 4.

[0028] The opening / closing mechanism 4 is capable of opening and closing the opening 24. Specifically, the opening / closing mechanism 4 includes a door portion 41 and a sound-absorbing member 42.

[0029] The sound-absorbing member 42 is positioned on the inner circumferential surface of the door section 41. The sound-absorbing member 42 absorbs vibrational sound transmitted to the iron rod.

[0030] As shown in Figure 3, the opening / closing mechanism 4 may have a connecting member 43. The door portion 41 is connected to the side wall 21 via the connecting member 43. The connecting member 43 may be, for example, a screw, or a hinge as shown in Figure 3. The door portion 41 can be rotatably moved around the connecting member 43. The opening / closing mechanism 4 does not have to have a connecting member 43, and the opening 24 may be opened and closed in any way. The opening / closing mechanism 4 may be removable from the side wall 21.

[0031] A gripping portion may be provided on the outer surface of the door portion 41 (not shown). The inspector can open and close the opening 24 by gripping the gripping portion and applying force.

[0032] By closing the opening 24 with the opening / closing mechanism 4, when the rope end portion 12 is not being inspected, the sound generated during the elevator's upward and downward movement is prevented from leaking out of the opening 24.

[0033] As shown in Figure 3, the rope cover 2 may be equipped with a light source 44. The light source 44 may be mounted, for example, on the inner surface of the side wall 21, or it may be mounted on the opening / closing mechanism 4 as shown in Figure 3. The light source 44 may be, for example, an LED (Light Emitting Diode).

[0034] The light source 44 may be controlled to turn off when the opening 24 is closed by the opening / closing mechanism 4. The light source 44 may be controlled to automatically turn on when the opening 24 is opened by the opening / closing mechanism 4. In this way, when an inspector opens the opening / closing mechanism 4 to inspect the rope end 12, the light source 44 will turn on, allowing the inspector to easily check the rope end 12.

[0035] As shown in Figure 3, the rope cover 2 may be equipped with a sensor 25. The sensor 25 may be attached, for example, to the inner surface of the side wall 21, or to the opening / closing mechanism 4. The sensor 25 detects that the opening 24 is open by the opening / closing mechanism 4. In other words, when an inspector opens the opening / closing mechanism 4 to inspect the rope end portion 12, the sensor 25 detects that the opening 24 is open. In this way, the elevator is controlled not to operate when the rope end portion 12 is being inspected.

[0036] Figure 4 is a schematic cross-sectional view of a modified example of the rope cover 2 according to Embodiment 2. The rope cover 2 shown in Figure 4 basically has the same configuration as the rope cover 2 shown in Figure 3 and can achieve the same effect, but differs in that it is equipped with a fastener 45. Figure 4 shows the opening 24 closed by the opening / closing mechanism 4.

[0037] When the opening 24 is closed by the opening / closing mechanism 4, the door portion 41 is fixed to the side wall 21 by the fastener 45. In other words, the fastener 45 controls the movement of the opening / closing mechanism 4 when the opening 24 is closed by the opening / closing mechanism 4. The fastener 45 may be provided on the outer circumferential surface of the side wall 21.

[0038] When the opening 24 is closed by the opening / closing mechanism 4, the door portion 41 may be fixed to the side wall 21 in any way. Specifically, the fastener 45 may be, for example, a snap fastener. The fastener 45 may also be a sealing member made of aluminum. In other words, by placing a sealing member at the boundary between the outer surface of the opening / closing mechanism 4 and the outer surface of the side wall 21, the leakage of sound generated during the elevator's upward and downward movement from the opening 24 is suppressed.

[0039] <Effects and Effects> The rope cover 2 described above is equipped with an opening / closing mechanism 4. The opening / closing mechanism 4 can open and close the opening 24.

[0040] In this way, by closing the opening 24 with the opening / closing mechanism 4, the sound generated during the elevator's upward and downward movement is suppressed from leaking out of the opening 24 when the rope end portion 12 is not being inspected.

[0041] The rope cover 2 described above is equipped with a sensor 25. The sensor 25 detects that the opening 24 is open by the opening / closing mechanism 4.

[0042] In this way, the elevator is controlled not to operate when the rope end section 12 is being inspected.

[0043] The rope cover 2 described above is equipped with a light source 44. The light source 44 is attached to the opening / closing mechanism 4.

[0044] In this way, when the inspector opens the opening / closing mechanism 4 and inspects the rope end portion 12, the light source 44 lights up, allowing the inspector to easily check the rope end portion 12.
