Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an elevator car, and more particularly to an elevator car having an improved joint structure of a side wall of a car room.

[0002]

[Prior Art]

 In general, the side wall of the elevator car is a place where the eyes of the user can be touched, and it is required that the side wall of the car has a certain aesthetic appearance in terms of color and the like. However, the above-mentioned side wall is apt to be scratched by the loaded luggage, and is relatively often scratched or soiled due to user mischief, such as being overwritten.

In order to solve this problem, the side wall of the car is made of stainless material to improve the effect. However, although this kind of side wall is almost satisfactory in terms of strength, it is aesthetically difficult because the color is limited.

On the other hand, recently, enameled wood has attracted attention as a building material for housing equipment such as buildings. This enamel material is rich in fire resistance, has almost no external damage even if it hits, and has the advantage that it is rich in color and has little deterioration. The use of such an enameled material for the side wall of the elevator car has been proposed in Japanese Patent Laid-Open No. 57-199981, and this car is shown in FIGS. 2, 3 and 4.

FIG. 4 is a side view showing a cross-sectional structure of the enamel plate. The glaze 7 is applied to the surface of the base metal 6 and dried, and then the enamel plate 1 is formed by firing at a temperature of 800 ° C. to 850 ° C.

FIG. 3 is a plan view of a side wall of a car 5 of an elevator having an entrance / exit, and the side wall is formed by joining and connecting a plurality of the enamel plates 1, that is, the enamel plates 1a and 1b. In addition, since firing strain is generated in the above-mentioned enamel plate 1 due to the difference in thermal expansion coefficient between the base metal 6 and the glaze 7, the enamel plates 1a and 1b have a width that does not adversely affect the calcination strain. It is configured by being divided into D ₁ , D ₂ and D ₃ . In this case, it is said that the dividing width is preferably about 300 to 500 mm.

FIG. 2 is an enlarged cross-sectional view of the joint portion of the enamel plates 1 a and 1 b on the side wall of FIG. 3 as seen from above. The first and second enamel plates 1a and 1b have an insertion piece 16 and a shielding piece 17 between a first joint portion 11 and a second joint portion 12, which are formed by bending their ends in the same direction. The joint 3 constituted by the above and the felts 2a and 2b are interposed on both sides of the insertion piece 16 and are integrally tightened by the bolt 4a, the spring washer 4b and the nut 4c.

By interposing the felts 2a and 2b on both sides of the insertion piece 16 of the joint 3 as described above, the hard insertion piece 16 hits the glazed surface of the above-mentioned joining portions 11 and 12 at the time of joining and joining. It is possible to prevent cracking and breaking of the glaze 7 of 11 and 12. In addition, the shielding piece 17 of the joint 3 conceals the felts 2a and 2b so as not to spoil the appearance of the car interior.

[0009]

[Problems to be solved by the device]

 The conventional elevator car described above does not give the elevator user a satisfactory aesthetic appearance with respect to the covering piece that covers the joint portion of the enamel board, and this covering piece does not protrude into the car room. Therefore, there is a fear that it will become an obstacle for users and luggage.

An object of the present invention is to provide a car that can prevent the curved surface of the joint portion of the enamel plate from being broken and can maintain a good appearance.

[0011]

[Means for Solving the Problems]

 The purpose of the above is that in the elevator car in which the side walls of the car are formed by joining and connecting a plurality of enamel plates at their ends, the joints formed at the respective ends of the adjacent enamel plates are connected to each other. This is achieved by making them face each other, interposing a joint between these two joints, and making the inner end face of the car of this joint almost coincide with the surface of the enamel plate.

[0012]

[Action]

 Since the curved surface of the joint portion of the enamel plate is protected by the joint due to the above-mentioned configuration, it is possible to prevent a luggage or the like from colliding with the curved surface by hitting the curved surface. In addition, since the joints do not protrude from the surface on the enamel side, there is no obstruction or loss of aesthetics as in the past.

[0013]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view of a side wall joint. The respective ends of the first enamel plate 1a and the second enamel plate 1b, which are one of the side walls, are bent at right angles in the same direction to form a first joint 11 and a second joint 12, A joint 18 is interposed between the joints 11 and 12. The car inner end surface 18a of the joint 18 substantially coincides with the surfaces of the enamel plates 1a and 1b, and is integrally tightened by the interposing bolt 4a, the spring washer 4b, and the nut 4c.

As described above with reference to FIG. 4, the first and second enamel plates 1 a and 1 b are obtained by applying glaze 7 on the surface of the base metal 6 and firing it. The joint 18 is formed of a material having a hardness lower than that of the glazes of the hollow plates 1a and 1b, for example, aluminum.

According to this embodiment, since the joint 18 formed of a material softer than the glaze 7 of the enamel plates 1a and 1b is interposed between the first and second joints 11 and 12, the joints are formed. Even when the load generated when the bolts 4a and the nuts 4c are tightened from both sides of the joints 11 and 12 acts on the glaze 7 and the joint 18 of the joints 11 and 12, the glaze 7 is not broken and broken.

Further, since the felt is not provided on both sides of the joint 18 as in the conventional case, a shielding piece for concealing the felt is not required, and the side wall of the car interior can be kept in a good condition. Further, since the inner surface of the car of the joint 18 is substantially aligned with the surfaces of the enamel plates 1a and 1b and is interposed between the joints 11 and 12, it is possible to prevent an elevator user or luggage from coming into contact with the curved surface of the joint. It is possible to prevent accidents such as injury or damage to the curved surface by touching the protruding joint as in the conventional case.

[0017]

[Effect of the device]

 As described above, according to the present invention, since the joints are interposed between the joints of the adjacent enamel plates so that the joints substantially coincide with the surface of the enamel plates on the side walls, it is possible to prevent the curved surface of the enamel plates from being damaged. The aesthetics of the car can be kept in good condition.
