Detailed Description
An embodiment of an elevator car disclosed in the present application will be described in detail below with reference to the drawings. The embodiments described below are examples, and the present invention is not limited to these embodiments.
Fig. 1 is a perspective view showing a main part of an elevator car according to embodiment 1 in a state where a handrail is raised. Fig. 2 is a perspective view showing a main part of the elevator car of embodiment 1 in a state where the handrail is laid down. Fig. 3 is a plan view and a side view showing a main part of an elevator car according to embodiment 1. Fig. 3 (a) is a plan view, and fig. 3 (b) is a side view. As shown in fig. 1, an elevator car 100 includes a car room 1, a car door 2, a door opening/closing device 3, a car frame 4, an upper frame 5, an armrest 6, and an armrest cover 9. The car room 1 forms a space in which passengers ride, and the car doors 2 are opened and closed by the door opening and closing device 3 so that passengers can enter the car room 1. The car door 2 is disposed so as to face a landing doorway (not shown) of an elevator. The door opening/closing device 3 opens and closes the car door 2. The door opening/closing device 3 is disposed above the car door 2 and fixed to project upward from the ceiling surface of the car room 1. Here, the landing side of the car room 1 in which the car doors 2 are installed is set as the front side. The X direction shown in fig. 3 (a) is the width direction in the plan view of the elevator car, and the Y direction is the depth direction in the plan view of the elevator car. Here, the width direction refers to the opening and closing direction of the car door 2, and the depth direction refers to the direction perpendicular to the front.
Fig. 4 is a front view showing a main part of the elevator car of embodiment 1 in a state where the handrail is laid down. As shown in fig. 4, the car room 1 is fixed to the car frame 4, and both side surfaces, ceiling surface, and bottom surface of the car room 1 when the landing side on which the door opening/closing device 3 is provided is the front surface are surrounded by the car frame 4. The car frame 4 on the upper surface side of the car room 1 is shown by a broken line. The car frame 4 supports the car room 1 by surrounding the car room 1.
As shown in fig. 1, 2, and 3, since the car frame 4 protrudes upward beyond the ceiling surface, the upper frame 5 supported by the car frame 4 on the ceiling surface of the car chamber 1 is supported with a predetermined gap from the ceiling surface of the car chamber 1.
The armrest 6 is provided so as to be able to shift between an upright state in which it is fixed to the ceiling surface of the car room 1 by standing up and a collapsed state in which it is fixed to the ceiling surface of the car room 1 by collapsing. Here, the standing state is a state fixed substantially vertically to the ceiling surface of the car room 1, and the falling state is a state fixed substantially horizontally to the ceiling surface of the car room 1. The armrest 6 does not need to be fixed vertically in the standing state, and does not need to be fixed horizontally in the falling state.
The handrail 6 of the elevator car 100 shown in fig. 1 is in a standing state, and the handrail 6 of the elevator car 100 shown in fig. 2 is in a falling state. The armrest 6 is composed of a pair of the 1 st armrest 6a and the 2 nd armrest 6b, the pair of the 1 st armrests 6a being provided in the vertical direction with respect to the ceiling surface of the car room 1 in the raised state of the armrest 6, and the 2 nd armrest 6b being provided in the horizontal direction with respect to the ceiling surface of the car room 1, and connecting the pair of the 1 st armrests 6a to each other.
As shown in fig. 1, a pair of armrests 6 are provided on the outer peripheral portions along both sides with respect to the front surface on the ceiling surface upper portion of the car room 1, and the armrests 6 are rotatably fixed to the upper frame 5 by a 1 st rotating portion 7 provided on the lower portion of the 1 st armrest 6a so that the armrests 6 can be shifted between the standing state and the collapsed state. The arrow a shown in fig. 1 indicates the rotation direction of the armrest 6. The handrail 6 is held in a standing state during maintenance work and in a falling state during normal operation of the elevator.
The handrail 6 has an auxiliary handrail 61 along an outer peripheral portion of a rear surface side of the ceiling surface upper portion of the car room 1. The assist grip 61 is fixed to the 1 st grip 6a on the back side of the grip 6 so as to be rotatable in the horizontal direction by the 2 nd rotation portion 8 in the standing state of the grip 6. In the example shown in fig. 1, the assist grip 61 is formed by dividing the assist grip 61a and the assist grip 61b in the horizontal direction. The arrow B shown in fig. 1 indicates the rotation direction of the assist grip 61a. In the standing state of the armrests 6, the assist grip 61a and the assist grip 61b provided on the pair of armrests 6 are fixed by the engaging portions 62.
As the 1 st rotation part 7 and the 2 nd rotation part 8, for example, a hinge, a link mechanism, a slide mechanism, or the like can be used. The engaging portion 62 may be configured to engage the assist grip 61 with each other by, for example, fitting or screwing.
The armrest cover 9 is provided on the armrest 6, and covers at least a portion of the ceiling surface of the car room 1 in the collapsed state of the armrest 6. Specifically, as shown in fig. 3 (a), the armrest cover 9 is configured to cover the entire armrest 6 and the ceiling surface of the car room 1 in the collapsed state of the armrest 6. The armrest cover 9 provided to the armrest 6 can suppress turbulence in the airflow caused by the airflow passing from the armrest 6 in the collapsed state toward the ceiling surface of the car room 1.
In fig. 2, the armrest cover 9 is provided above the armrest 6 in the collapsed state of the armrest 6, but may be provided below the armrest 6. When the armrest cover 9 is provided below the armrest 6, the armrest cover 9 can prevent the airflow from flowing from the armrest 6 in the collapsed state toward the ceiling surface of the car room 1 and from being disturbed. That is, if the armrest cover 9 is provided on the armrest 6 and the armrest cover 9 covers the ceiling surface of the car room 1 in the collapsed state of the armrest 6, it is possible to suppress turbulence in the airflow that occurs when the airflow passes from the armrest 6 in the collapsed state toward the ceiling surface of the car room 1, and therefore, it is possible to suppress noise that occurs in the upper portion of the car room 1. Here, the upper side refers to the outside of the armrest 6 in the standing state, and the lower side refers to the inside of the armrest 6 in the standing state.
As shown in fig. 1, 2 and 3, the following examples are shown: when the ceiling of the car room 1 is rectangular, the outer shape of the armrest cover 9 is also rectangular in the collapsed state of the armrest 6, but the shape of the armrest cover 9 is not limited to rectangular, and may be, for example, substantially polygonal or elliptical. The armrest cover 9 is fixed to the armrest 6 by bolts, welding, or the like, for example. The armrest cover 9 is required to withstand wind pressure when the car room 1 is lifted and lowered, and is made of steel plate, aluminum plate, carbon sheet, or the like as a raw material.
Next, a maintenance operation on the ceiling surface of the car room 1 will be described.
During maintenance work, before entering the ceiling surface of the car room 1, a maintenance worker grips and lifts the front end portions of the pair of handrails 6 provided on both sides of the ceiling surface of the car room 1. Next, the maintenance worker enters the ceiling of the car room 1 and fixes the assist grip 61 provided on each of the pair of grips 6 by the engaging portion 62. Thereby, the elevator car 100 is assembled in the state shown in fig. 1. Therefore, a maintenance worker performs maintenance work of the equipment in the hoistway on the ceiling surface on which the handrail 6 is provided in the erected state after the assembly shown in fig. 1.
In the elevator car 100 according to embodiment 1, the handrail cover 9 receives an airflow that collides with the devices provided on the ceiling of the car room 1 and the handrail 6. The armrest cover 9 provided to the armrest 6 can suppress turbulence in the airflow that occurs when the airflow passes from the armrest 6 in the collapsed state toward the ceiling surface of the car room 1, and can suppress noise that occurs in the upper portion of the car room 1. By suppressing noise generated in the upper portion of the car room 1, the interior of the car room 1 can be muted, and the comfort of passengers can be improved.
In the elevator car 100 according to embodiment 1, since the handrail 6 is provided on the upper frame 5 supported with a predetermined gap from the ceiling surface of the car chamber 1, a gap space is also formed between the handrail cover 9 and the ceiling surface of the car chamber 1 in the collapsed state of the handrail 6. By forming the gap space, interference between the armrest cover 9 and equipment (e.g., a ventilator) provided on the ceiling of the car room 1 can be prevented without using a special structure. Further, since the clearance space is formed, the ventilation flow path can be ensured, and therefore, a reduction in ventilation capability of the ventilator is suppressed, and a reduction in heat discharge performance of equipment provided on the ceiling of the car room 1 is suppressed.
Further, the armrest cover 9 of the elevator car 100 according to embodiment 1 is not a structure that prevents the armrest 6 from being shifted from the collapsed state to the raised state, and therefore the armrest 6 can be efficiently assembled.
The elevator car 100 of embodiment 1 includes: a car room; a handrail which is provided on an upper portion of a ceiling surface of the car room and is capable of being switched between a standing state and a falling state; and a handrail cover that is provided to the handrail and covers at least a part of the ceiling surface in a state where the handrail is laid down.
With the above configuration, the elevator car 100 according to embodiment 1 can suppress noise generated in the upper portion of the car room.
The elevator car 100 according to embodiment 1 is further characterized by further comprising: a car frame surrounding the car room and supporting the car room; and an upper frame supported by the car frame at a position spaced apart from the ceiling surface, wherein the handle is provided on the upper frame.
With the above configuration, the elevator car 100 according to embodiment 1 can secure the ventilation flow path, and therefore, a reduction in ventilation capability of the ventilation device and a reduction in heat discharge performance of equipment provided on the ceiling of the car room 1 can be suppressed.
A structure of an elevator car 200 according to embodiment 2 of the present invention will be described. Note that the description of the same or corresponding structure as that of embodiment 1 is omitted, and only the portions having different structures will be described.
Fig. 5 is a plan view and a side view showing a main part of an elevator car of embodiment 2 in a state where a handrail is laid down. Fig. 5 (a) is a plan view, and fig. 5 (b) is a side view. The elevator car 200 is configured such that the adjustment mechanism 11 adjusts the mounting position of the handle cover 9 fixed to the handle 6, thereby changing the gap width between the handle cover 9 of the handle 6 and the door opening/closing device 3 in a collapsed state.
As shown in fig. 5, the handle cover 9 of the elevator car 200 is fixed to the handle 6 by the adjustment mechanism 11. Specifically, the fixing hole of the armrest cover 9 for fixing to the armrest 6 is an elongated hole 11a, and the armrest cover 9 is attached to the armrest 6 by a fixing member 11b such as a bolt. The adjustment mechanism 11 is composed of a long hole 11a and a fixing member 11b. Since the fixing hole for fixing the armrest cover 9 to the armrest 6 is the elongated hole 11a, the attachment position of the armrest cover 9 to the armrest 6 can be adjusted by loosening the fixing member 11b, and the armrest cover 9 can be attached to the armrest 6 by fastening the fixing member 11b after the position of the armrest cover 9 to the armrest 6 is adjusted. By appropriately selecting the shape of the elongated hole 11a, the adjustment direction of the armrest cover 9 can be determined. In the example shown in fig. 5, the shape of the elongated hole 11a is an elliptical shape having a long axis in the depth direction in a plan view of the elevator car, so that the installation position of the armrest cover 9 with respect to the armrest 6 can be adjusted in the depth direction.
As shown in fig. 5, in the collapsed state of the armrest 6, the gap between the armrest cover 9 and the door opening/closing device 3 is defined as a gap d1. Part of the air flow colliding with the upper portion of the door opening/closing device 3 and part of the air flow colliding with the armrest cover 9 during the raising and lowering flow through the gap d1 between the armrest cover 9 and the door opening/closing device 3. When the gap d1 exists between the armrest cover 9 and the door opening/closing device 3, a gap noise is generated when the airflow passes through the gap d1 between the armrest cover 9 and the door opening/closing device 3.
The gap sound is a resonance sound. Therefore, when suppressing the gap noise, it is effective to adjust the width of the gap d1 between the armrest cover 9 and the door opening/closing device 3 or to eliminate the gap d1 between the armrest cover 9 and the door opening/closing device 3.
The clearance d1 between the armrest cover 9 and the door opening/closing device 3 is preferably 20mm or less, and more preferably, the clearance d1 between the armrest cover 9 and the door opening/closing device 3 decreases as the elevator lifting speed increases. Most preferably, the gap d1 between the armrest cover 9 and the door opening/closing device 3 is narrow enough to prevent the gap sound from being generated by the abutment of the front side of the armrest cover 9 with the door opening/closing device 3.
Since the elevator car 200 according to embodiment 2 can adjust the mounting position of the armrest cover 9 fixed to the armrest 6 by the adjustment mechanism 11, in addition to the effect of suppressing noise generated in the upper portion of the car room 1 described in embodiment 1, it is possible to suppress noise when a part of the airflow that collides with the upper portion of the door opening/closing device 3 and a part of the airflow that collides with the armrest cover 9 pass through the gap d1 between the armrest cover 9 and the door opening/closing device 3.
The elevator car 200 according to embodiment 2 is characterized by further comprising a door opening/closing device that is provided at the upper part of the car room and opens/closes the door of the car room, and the armrest cover is attached to the armrest by an adjustment mechanism that adjusts the attachment position of the armrest cover provided on the armrest, thereby changing the gap width between the armrest cover of the armrest and the door opening/closing device in the collapsed state.
With the above configuration, the elevator car 200 according to embodiment 2 can suppress noise when part of the airflow colliding with the upper portion of the door opening/closing device 3 and part of the airflow colliding with the armrest cover 9 pass through the gap d1 between the armrest cover 9 and the door opening/closing device 3.
A structure of an elevator car 300 according to embodiment 3 of the present invention will be described. Note that the description of the same or corresponding structure as that of embodiment 1 is omitted, and only the portions having different structures will be described.
Fig. 6 is a plan view and a side view showing a main part of an elevator car of embodiment 3 in a state where a handrail is laid down. Fig. 6 (a) is a plan view and fig. 6 (b) is a side view. The elevator car 300 is configured such that the handrail cover 9 has a cover member 21, and the cover member 21 covers at least a part of a gap d1 between the handrail cover 9 and the door opening/closing device 3 of the handrail 6 in the laid-down state.
As shown in fig. 6, the armrest cover 9 of the elevator car 300 has a cover member 21, and the cover member 21 covers a gap between the armrest cover 9 of the armrest 6 and the door opening/closing device 3 in the collapsed state. The cover member 21 is made of, for example, steel or aluminum. The cover member 21 is manufactured by, for example, press working or injection molding.
In the example shown in fig. 6 (b), the cover member 21 includes a lower plate portion 21a, a support plate portion 21b, and an upper plate portion 21c. In the example shown in fig. 6 (b), the lower plate portion 21a is fixed to the armrest cover 9, the upper plate portion 21c is positioned above the door opening/closing device 3, and the support plate portion 21b extends vertically upward from the lower plate portion 21a to the upper plate portion 21c, and is integrated with the lower plate portion 21a and the upper plate portion 21c. The cover member 21 is fixed to the armrest cover 9 by, for example, bolts, welding, or an adhesive material.
The shape of the cover member 21 is not limited to the shape shown in fig. 6, and may be any shape as long as it covers the gap d1 between the armrest cover 9 of the armrest 6 in the collapsed state and the door opening/closing device 3. Fig. 7 is a diagram showing a modification of the cover member of the elevator car according to embodiment 3 in a state where the handle is laid down. In the example shown in fig. 7 (a), the cover member 21 includes a lower plate portion 21a, a support plate portion 21b, and an upper plate portion 21c. In the cover member 21 shown in fig. 7 (a), the lower plate portion 21a is fixed to the armrest cover 9, the upper plate portion 21c is positioned above the door opening/closing device 3, and the support plate portion 21b integrated with the lower plate portion 21a and the upper plate portion 21c has an arc shape protruding downward. In the example shown in fig. 7 (b), the cover member 21 has a lower plate portion 21a and a support plate portion 21b. In the cover member 21 shown in fig. 7 (b), the lower plate portion 21a is fixed to the armrest cover 9, and an end portion of an upwardly-projecting arc-shaped support plate portion 21b extending from the lower plate portion 21a toward the upper portion of the door opening/closing device 3 is positioned above the door opening/closing device 3. In the example shown in fig. 7 (c), the cover member 21 has a lower plate portion 21a and a support plate portion 21b. In the cover member 21 shown in fig. 7 (c), the lower plate portion 21a is fixed to the armrest cover 9, and the end portion of a linear support plate portion 21b extending from the lower plate portion 21a toward the upper portion of the door opening/closing device 3 is positioned above the door opening/closing device 3. In the example shown in fig. 7 (d), the cover member 21 includes a lower plate portion 21a, a support plate portion 21b, and an upper plate portion 21c. In the cover member 21 shown in fig. 7 (d), the lower plate portion 21a is fixed to the armrest cover 9, the upper plate portion 21c is positioned above the door opening/closing device 3, the support plate portion 21b is inclined with respect to the lower plate portion 21a, and the support plate portion 21b is integrated with the lower plate portion 21a and the upper plate portion 21c. As shown in fig. 7, the cover member 21 may have a shape that covers the gap d1 between the armrest cover 9 and the door opening/closing device 3.
By reducing the gap d1 between the armrest cover 9 and the door opening/closing device 3, the cover member 21 can suppress noise generated when part of the airflow that collides with the upper portion of the door opening/closing device 3 and part of the airflow that collides with the armrest cover 9 pass through the gap d1 between the armrest cover 9 and the door opening/closing device 3. In fig. 6 and 7, an example in which the cover member 21 covers the entire gap d1 between the armrest cover 9 of the armrest 6 and the door opening/closing device 3 in the collapsed state is described, but it is not necessary to cover the entire gap d1, and the cover member 21 may have a shape that covers at least a part of the gap d1.
Since the cover member 21 of the elevator car 300 according to embodiment 3 covers the gap d1 between the armrest cover 9 of the armrest 6 and the door opening/closing device 3 in the collapsed state, part of the airflow that interferes with the upper portion of the door opening/closing device 3 and part of the airflow that interferes with the armrest cover 9 pass through the gap d1. Therefore, the elevator car 300 according to embodiment 3 can suppress noise when part of the airflow colliding with the upper portion of the door opening/closing device 3 and part of the airflow colliding with the armrest cover 9 pass through the gap d1.
The elevator car 300 according to embodiment 3 is characterized by further comprising a door opening/closing device that is provided above the car room and opens/closes the door of the car room, and the armrest cover has a cover member that covers at least a part of the gap between the armrest cover and the door opening/closing device of the armrest in the collapsed state.
With the above configuration, the elevator car 300 according to embodiment 3 can suppress noise when part of the airflow colliding with the upper portion of the door opening/closing device 3 and part of the airflow colliding with the armrest cover 9 pass through the gap d1 between the armrest cover 9 and the door opening/closing device 3.
Next, a modified example of the shape of the cover member 21 will be described. Fig. 8 and 9 are views showing modifications of the cover member of the elevator car according to embodiment 3 in a state where the handle is laid down.
Fig. 8 is a plan view and a side view showing a main part of an elevator car of embodiment 3 in a state where a handrail is laid down. Fig. 8 (a) is a plan view and fig. 8 (b) is a side view. The cover member 22 shown in fig. 8 is a flat plate-like member having one end fixed to the armrest cover 9 and the other end in contact with the door opening/closing device 3. The cover member 22 is made of, for example, rubber, and is fixed to the armrest cover 9 by bolts, adhesive, or the like.
Fig. 9 is a plan view and a side view showing a main part of an elevator car of embodiment 3 in a state where a handrail is laid down. Fig. 9 (a) is a plan view, and fig. 9 (b) is a side view. The cover member 23 shown in fig. 9 is composed of a brush portion 23a and a fixing portion 23b. The brush portion 23a is provided with a plurality of rod-shaped or plate-shaped members, and the brush portion 23a is fixed to the fixing portion 23b. The fixing portion 23b of the cover member 23 is fixed to the armrest cover 9, and the brush portion 23a is in contact with the door opening/closing device 3. The fixing portion 23b of the cover member 23 is fixed to the armrest cover 9 by, for example, bolts, welding, or an adhesive material.
Although the cover members 22 and 23 of the elevator car 300 shown in fig. 8 and 9 have been described as examples in which one end portions thereof are in contact with the door opening/closing device 3, noise generated when part of the airflow that collides with the upper portion of the door opening/closing device 3 and part of the airflow that collides with the armrest cover 9 pass through the gap d1 between the armrest cover 9 and the door opening/closing device 3 can be suppressed by reducing the gap d1 between the armrest cover 9 and the door opening/closing device 3, and therefore, the one end portions of the cover members 22 and 23 do not necessarily have to be in contact with the door opening/closing device 3.
A structure of an elevator car 400 according to embodiment 4 of the present invention will be described. Note that the description of the same or corresponding structure as that of embodiment 1 is omitted, and only the portions having different structures will be described.
Fig. 10 is a perspective view showing a main part of an elevator car of embodiment 4 in a state where a handrail is raised. Fig. 11 is a plan view showing a main part of the elevator car of embodiment 4 in a state where the handrail is laid down. The elevator car 400 is configured to divide the armrest cover 9 into a plurality of pieces.
By dividing the armrest cover 9, the armrest cover 9 can be attached to the armrest 6 from an arbitrary location. For example, as shown in fig. 10, the armrest cover 9 is configured to be divided in the horizontal direction in the standing state of the armrest 6. Therefore, in the collapsed state of the armrest 6, the divided armrest cover 9 can be attached from the back side, and therefore, a scaffold for attachment of the armrest cover 9 is not required, and the time required for attachment of the armrest cover 9 can be reduced.
As shown in fig. 11, by attaching the armrest cover 9 to the armrest 6 using the adjustment mechanism 11, the distance d2 between the divided armrest covers 9 can be adjusted to fix the armrest cover 9. Here, in fig. 11, the adjustment mechanism 11 has a long hole 11a having a circular shape with a long axis in the depth direction and a fixing member 11b. Therefore, in the elevator car 400 according to embodiment 4, since the armrest cover 9 can be fixed to the armrest 6 by adjusting the depth-direction distance d2 between the divided armrest covers 9, noise generated in the upper portion of the car room 1, such as gap noise generated from the gap between the divided armrest covers 9, can be suppressed, and the installation work time can be reduced without impairing the comfort of the passengers in the car room 1. Alternatively, the armrest cover 9 may be fixed to the armrest 6 by adjusting the width-directional gap d3 of the armrest cover 9 attached to each of the pair of armrests 6 by making the elongated hole 11a of the adjustment mechanism 11 have an elliptical shape having a long axis in the width direction, and the pair of armrests 6 may be provided on both sides of the ceiling surface of the car room 1.
An elevator car 400 according to embodiment 4 is characterized in that the armrest cover is divided into a plurality of pieces in the vertical direction in the raised state of the armrests.
With the above configuration, the elevator car 400 according to embodiment 4 can reduce the time required for the installation work of the armrest cover 9.

Therefore, the elevator car 500 according to embodiment 5 can suppress noise generated in the upper portion of the car room 1, such as gap noise generated from the gap between the handrail covers 9 attached to the pair of handrails 6, respectively, the pair of handrails 6 being provided on both sides of the ceiling surface of the car room 1.
Further, as shown in fig. 12, by attaching the buffer member 31 to the armrest cover 9 so as to be sandwiched by the overlapping portion of the armrest cover 9 in the collapsed state of the armrest 6, it is possible to suppress gap noise generated when a part of the airflow colliding with the armrest cover 9 flows into the gap at the overlapping portion of the armrest cover 9. The buffer member 31 is made of, for example, rubber, and is fixed to the armrest cover 9 by an adhesive or the like.
An elevator car 500 according to embodiment 5 is characterized in that the ceiling surface has a rectangular shape, the pair of door opening and closing devices are provided on the sides of the ceiling surface with respect to the armrests, and at least a part of the armrest cover provided on one armrest and at least a part of the armrest cover provided on the other armrest overlap on the ceiling surface in the collapsed state of the armrests.
With the above configuration, the elevator car 500 according to embodiment 5 can suppress noise generated in the upper portion of the car room 1, such as gap noise generated from the gap between the handrail covers 9 attached to the pair of handrails 6, respectively, the pair of handrails 6 being provided on both sides of the ceiling surface of the car room 1.
A structure of an elevator car 600 according to embodiment 6 of the present invention will be described. Note that the description of the same or corresponding structure as that of embodiment 1 is omitted, and only the portions having different structures will be described.
Fig. 14 is a perspective view showing a main part of an elevator car of embodiment 6 in a state where a handrail is raised. The elevator car 600 is configured to have a sound absorbing material 41 on the inner surface of the handle cover 9.
As shown in fig. 14, the armrest cover 9 of the elevator car 600 is provided with a sound absorbing material 41 on the inner surface of the armrest 6 in the standing state, that is, on the lower surface of the armrest 6 in the collapsed state. The sound absorbing material 41 is formed of, for example, a sponge material, glass wool, rock wool, or the like. The sound absorbing material 41 is fixed to the armrest cover 9 by, for example, bolts or an adhesive.
The sound absorbing material 41 absorbs a part of noise such as wind noise and echo generated in a gap space formed between the car room 1 and the armrest cover 9 in the collapsed state of the armrest 6, and converts the noise into heat energy. Therefore, the elevator car 600 according to embodiment 6 suppresses noise such as wind noise and echo generated in the clearance space, and improves the comfort of passengers.
The elevator car 600 according to embodiment 6 is characterized in that the surface of the handrail cover on the lower side in the laid-down state of the handrail has a sound absorbing material.
With the above configuration, the elevator car 600 according to embodiment 6 can suppress noise generated in the gap space.

Fig. 16 shows the following state: in the standing state of the armrest 6, the assist grip 61a is turned in the direction of arrow B shown in fig. 15, the assist grip 61B is turned in the direction of arrow C shown in fig. 15, and the assist grip 61 is fixed to the side surface of the armrest 6. As shown in fig. 16, a handrail cover 9 is provided on the handrail 6 of the elevator car 700 on the outer side and the inner side in the standing state of the handrail 6. That is, the armrest cover 9 is provided on both sides of the armrest 6. Fig. 16 shows the armrest cover 9 provided on the inner side of the armrest 6 in the standing state, with oblique lines. The armrest cover 9 provided on the outer side is integrally formed, but the armrest cover 9 provided on the inner side is divided so that the assist armrest 61 can rotate in the horizontal direction in the raised state of the armrest 6. For example, as shown in fig. 16, the armrest cover 9 has an armrest cover 9a, an armrest cover 9b, and an armrest cover 9c. The armrest cover 9a is divided into the same shape as the assist armrest 61a, and is attached to the assist armrest 61a. The armrest cover 9b is attached to the armrest 6 vertically below the assist armrest 61a. The armrest cover 9c is attached to the armrest 6 on the front side where the armrest cover 9a and the armrest cover 9b are not provided. Although fig. 15 shows an example in which the armrest cover 9b and the armrest cover 9c are divided, the armrest cover 9b and the armrest cover 9c may be integrated.
A part of the noise generated on the outer surface of the armrest cover 9 when the car room 1 is raised is transmitted into the car room 1 through the armrest cover 9. Therefore, the armrest cover 9 is provided so as to sandwich the armrest 6 therebetween, and the sound insulation performance of the armrest cover 9 is improved, thereby suppressing the transmission of noise to the car room 1.
In the elevator car 700 according to embodiment 7, the handrail cover 9 is provided so that the handrail 6 is interposed therebetween, and the sound insulation performance of the handrail cover 9 is improved. Therefore, the elevator car 700 according to embodiment 7 suppresses the noise generated on the outer surface of the handle cover 9 from being transmitted to the car room 1 when the car room 1 is raised, and thus improves the comfort of the passengers.
Further, by inserting the sound absorbing material into the inner space of the armrest cover 9 with the armrest 6 interposed therebetween, noise in a specific frequency band corresponding to the type of the sound absorbing material can be reduced.
The elevator car 700 according to embodiment 7 is characterized in that a handrail cover is provided so as to sandwich a handrail.
With the above configuration, the elevator car 700 according to embodiment 7 can suppress the transmission of noise generated on the outer surface of the handle cover 9 to the car room 1 when the car room 1 is raised.
