2. Description of the Related Art An elevator car is constructed by attaching a car door to a box-shaped cab having a floor panel, a ceiling panel, side panels and a back panel. Further, the car room is provided with a car frame on which a guide roll or the like which is in contact with a guide rail for guiding the ascending and descending of the car is mounted while supporting and reinforcing the car.

[0003] In a conventional elevator car, a cab or a car frame is mostly made of a metal plate such as an aluminum alloy plate or a steel plate. However, such a car is heavy.
Not only large power is required, but also the inertia is high, so advanced control is required for operation. In particular, recently, in a home elevator which is rapidly spreading in houses for the elderly and the like, since a home power supply is used, reduction of power by weight reduction is strongly demanded.

In response to such a demand, Japanese Patent Application Laid-Open No. 64-1
No. 7790 proposes that the cab be constructed of a single plate with FRP reinforcing ribs. This conventional cab is F
Because it is made of RP, it is lighter than one made of metal plate, but it has reinforcing ribs, but in order to use the veneer, to secure the required rigidity and strength,
It is inevitable that the thickness of the plate and the size of the reinforcing ribs increase, and the increase in the thickness of the plate and the size of the reinforcing ribs increase the weight. Absent.

[0005] Another important characteristic required for an elevator is vibration damping performance. From the viewpoint of ride comfort, the higher the vibration damping performance is, the more preferable it is. However, in the conventional elevator as described above, it cannot be said that sufficient consideration has been given to the vibration damping performance.

Further, especially in a home elevator or the like, not only the moldability of the elevator car but also the excellent assemblability on site is required.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of an elevator car according to the present invention will be described below with reference to the drawings. FIG. 1 shows a home elevator using an elevator car according to an embodiment of the present invention. In the figure, reference numeral 1 denotes the entire elevator, and the elevator 1
Has a car room 2, a car frame 3, and a suspension wire 4 in this embodiment. The car frame can also be formed integrally with the cab component, as described later.

The car room 2 has side plates 5, 6, a ceiling plate 7, a back plate 8, a floor plate 9, and a door 10 as its constituent members. At least a part of these constituent members is formed of a member including an FRP plate.

Further, the vibration damping coefficient ratio of the component including the FRP plate is at least 0.002 (that is, 0.002
Preferably, the vibration damping coefficient ratio of the entire cab 2 is at least 0.005 (that is, 0.005 or less).
Above) . The higher the value of the vibration damping coefficient ratio is, the higher the vibration damping performance is, but if it is set to be too high, the manufacturing cost rapidly increases. The above value may be used. The more preferable value of the vibration damping coefficient ratio of the component including the FRP plate is at least 0.005, and the more preferable value is at least 0.01. A more preferable value of the vibration damping coefficient ratio of the entire cab is
It is at least 0.01, and a more preferred value is at least 0.02.

The vibration damping coefficient ratio according to the present invention is measured as follows. That is, the vibration damping coefficient ratio according to the present invention is obtained as follows from a transfer function based on an excitation response using a fast Fourier transform (FFT).

For example, as shown in FIG. 2, the acceleration sensor 202 is set at the center of the panel surface 203 of the component member 200 while the component member 200 of the cab including the FRP plate is suspended by the rubber 201 having a diameter of 5 mm. Acceleration sensor 202
180 ° opposite to the end of the panel with the electromagnetic shaker 20
4 excites through the force sensor 205. At this time, white noise was used as the excitation frequency. The signals of both the acceleration sensor 202 and the force sensor 205 obtained by this measurement are taken into the FFT analyzer 206 to obtain a transfer function, and the calculation of a vibration damping coefficient ratio is performed by a calculation program. The vibration damping coefficient ratio is obtained by an operation of reconstructing a curve of the transfer function (curve fitting) by separating and formulating a significant eigenmode characteristic from the obtained transfer function. The larger the vibration damping coefficient ratio, the higher the vibration damping performance of the component member 200.

As for the vibration damping coefficient ratio of the entire cab,
The entire cab is suspended by the rubber 201, and the measurement is performed in exactly the same manner as shown in FIG.

The vibration damping coefficient ratio measured in this way is:
At least 0.002, preferably at least 0.005 for measurements of cab components including FRP plates;
The cage including the FRP plate is more preferably at least 0.01, and at least 0.005, preferably at least 0.01, and more preferably at least 0.02 in the case of the measurement of the entire cab. The chamber components or the entire cab are formed.

The components of the cab are formed in the following manner. For example, as shown in FIG. 3, at least a part of the component member 11 may be formed of a single FRP plate.
However, in the present invention, as shown in FIG.
At least a part of 2 is formed in a sandwich panel structure in which the FRP plates 13 and 14 are used as skin materials and a core material 15 is arranged between the skin materials 13 and 14. Alternatively, the present invention
Then, as shown in FIG. 5, at least a part of the component member 16 is formed in a hollow cross-sectional panel structure using the FRP plate as skin members 17, 18 and a stringer 19.

As shown in FIG. 6, a tubular reinforcing spar 21 may be provided to improve the strength and rigidity of the sandwich panel 20. It is also possible to form a car frame at the portion where the reinforcing spar 21 is provided, and to form the car frame integrally with the sandwich panel 20.

Similarly, as shown in FIG. 7, a reinforcing spar 23 can be provided on the hollow section panel 22, and a car frame is formed at the reinforcing spar 23, and the car frame is integrated with the hollow section panel 22. It is also possible to form.

The above-mentioned sandwich panel section and hollow section panel section should be formed at least 20% with respect to the total area of each component member of the cab including the FRP plate. It is preferable from the viewpoint of maximizing the lightening effect while ensuring the strength and rigidity of the above. In particular, it is preferable to dispose the cab in the center of each face where the amount of deformation caused by the load on each face becomes maximum. By arranging the sandwich panel portion and the hollow section panel portion at the center of each surface in this way, and having the end portion and the corner portion of each surface in a single FRP plate structure, the moldability of each component is improved. . That is, if a sandwich panel portion or the like is disposed at an end portion or a corner portion of each component, there is a possibility that molding time will increase and manufacturing costs will increase. However, depending on the shape of the cab and the molding method, it is also possible to configure substantially all the parts with a sandwich panel or a hollow section panel.

The FRP plate constituting the skin material or the like of the sandwich panel or a hollow cross-section panels, made of a composite material of the reinforcing fibers and the matrix resin.

As the reinforcing fibers, high-strength, high-modulus fibers such as carbon fibers, glass fibers, and polyaramid fibers can be used. As the form of the reinforcing fiber, prepreg, woven fabric, mat, roving cloth, strand, or the like can be used. Above all, carbon fiber excellent in specific strength and specific elastic modulus, which has a tensile strength of 4,400 MPa
As described above, when the carbon fiber having the tensile elongation of 1.7% or more is used, the impact resistance of the cab constituent members and the entire cab is improved.

As the matrix resin, a thermosetting resin such as an epoxy resin, an unsaturated polyester resin, a phenol resin or a vinyl ester resin, or a thermoplastic resin such as a nylon resin, a polyetherimide resin, or a polypropylene resin can be used. . Among them, a phenol resin having excellent flame retardancy is preferable, but the above-mentioned thermosetting resin or thermoplastic resin is brominated or chlorinated to make it flame-retardant, or an antimony trioxide or a flame retardant such as a halogen compound is added. It can also be used after flame retardation.

The core material of the sandwich panel is preferably a foam (foam) such as polyvinyl chloride resin, polyurethane resin, polystyrene resin, polyethylene resin, polypropylene resin, acrylic resin, phenol resin, polymethacrylimide resin, epoxy resin and the like. It is. Above all, a rigid foam such as an acrylic resin or a polymethacrylimide resin, which has a large effect of improving rigidity and strength, is preferable. As the core material, an inorganic foam such as an aluminum foam or a syntactic foam can be used. Further, an aluminum honeycomb, a paper honeycomb, or a honeycomb body obtained by impregnating a honeycomb of polyaramid fiber paper with a phenol resin or the like can be used. The core material has a density of 0.01 to 0.2 g / c in order to further reduce the weight and strength of the sandwich panel.
Those in the range of m ³ are preferred. 0.01 g / cm ³
If it is smaller than this, the buckling of the sandwich panel is likely to occur, and if it is larger than 0.2 g / cm ³ , the effect of reducing the weight is reduced.

The FRP skin material can be formed, for example, by laminating a prepreg of the above-mentioned reinforcing fiber in a predetermined lamination structure on a mold surface, and then heating and pressing. Alternatively, a skin material can be formed on the mold surface while shaping the mold surface while impregnating each reinforcing fiber with a resin.

The sandwich plate portion is formed by arranging a core material between the skins when laminating the FRP skin materials. Alternatively, a sandwich panel can be obtained by forming a skin material by each of the above methods and then bonding the skin material to both surfaces of the core material.

The skin material of the sandwich panel is made of, for example, GF using at least glass fiber as a reinforcing fiber.
It is preferable to be made of RP (glass fiber reinforced plastic). In this case, the thickness of the GFRP layer is preferably 2 to 4 mm, and the thickness of the core material is preferably about 5 to 40 mm from the viewpoint of strength and rigidity. As the form of the glass fiber to be used, mats and cloths are preferable in terms of moldability.

In the elevator car of the present invention, it is preferable to provide a surface decorative layer on the surface of the FRP plate forming the inner surface of the cab (that is, the surface on the indoor side).

It is preferable to provide a surface decorative layer 34 on the indoor side, and to provide a surface decorative layer 36 on the indoor side of the hollow cross-sectional panel 35 in the hollow cross-sectional panel 35 as shown in FIG.

By providing such a surface decorative layer, it is possible to enhance the design of the interior of the elevator room and to give the interior a sense of quality. As a surface decorative layer,
A resin layer, a gel coat layer, a layer formed by attaching a cloth, wallpaper, or a sheet material, or a layer formed by various coatings can be used. Furthermore, it is also possible to form a slit-shaped groove on the surface, particularly a large number of slit-shaped grooves extending in the horizontal direction, or to form a surface decorative layer by subjecting the surface to graining.

The provision of a slit groove is particularly preferable in human physiology. This is because, if the room is formed with a smooth surface, there is a possibility that a sense of balance may be disturbed visually when a person gets on the vehicle, which may cause a bad feeling. The shape of the slit groove is R5
~ 12mm, pitch 10 ~ 30mm, depth 0.3 ~ 1m
m is preferable. This effect can be obtained by setting the range in which the slit groove is provided as the range of the passenger's visual field. By machining the slit groove in advance on the mold surface at the time of FRP molding, it is possible to form the slit groove stably.
