Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a side wall of a car of an elevator, and more particularly to a side wall of a car of an elevator in which a enamel-treated decorative panel is arranged on a surface of a side plate.

[0002]

[Prior art]

 As described in Japanese Patent Application No. 2-323042, a conventional elevator car side wall has a enamel-treated decorative panel on the surface of a side plate, and the facing portion of the decorative panel covers the end of the decorative panel. The joint bolts are arranged on the side plate of the decorative panel, and the stud bolts provided on the back side of the joint are inserted into the through holes provided on the side plate corresponding to the facing part of the decorative panel. Was.

[0003]

[Problems to be solved by the device]

 However, since the side wall of the elevator car of the conventional elevator has the above-described structure, when stainless steel is used as the joint material in consideration of aesthetics, the slight vibration generated when the elevator is running causes the back surface of the joint to be damaged. It was found that friction between the surface of the decorative panel and the surface of the decorative panel caused a squeak noise.

An object of the present invention is to provide an elevator car side wall that does not generate a squeaking noise regardless of a joint material.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a decorative panel on the surface of an adjacent side plate and fixes the joint at a position corresponding to the joint of the decorative panel. A spacer that is thicker than the decorative panel is provided between the side plate and a gap, and a gap is formed between the surface of the decorative panel and the back surface of the joint.

[0006]

[Action]

 As described above, the elevator car side wall according to the present invention has a gap between the joint back surface and the decorative panel surface.As a result, even if a slight vibration is generated by the elevator traveling, the joint back surface and the decorative panel surface are generated. There was no friction between and no creaking noise was generated, and a quiet elevator car side wall was obtained.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a lateral cross-sectional view of a side wall of a car of an elevator according to an embodiment of the present invention. Adjacent side plates 10 and 11 have their opposite ends bent at substantially right angles to the back surface to form upright portions 10a and 11a, and a drop joint 12 is interposed between these upright portions 10a and 11a. Not tightened with bolts and nuts for connection. Decorative panels 1 and 2 in which enamels 1b and 2b are formed on the surfaces of thin base metal plates 1a and 2a are adhered to the surface sides of both side plates 10 and 11, respectively. A seam is formed between the adjacent decorative panels 1 and 2 depending on the baking width. The seam is taken into consideration in the bonding position of the decorative panels 1 and 2 so as to avoid the seam due to the drop joint 12 of the side plates 10 and 11. ing. In the illustrated embodiment, the joint between the decorative panels 1 and 2 is located at a position displaced from the drop joint 12 toward the side plate 10. A plurality of through holes 10b are formed in the side plate 10 at a position corresponding to the seam along the seam direction at predetermined intervals, and the spacer 7 also has through holes 7a at the same intervals as the through holes 10b. Is forming.

Further, the joint 3 arranged at the joint of the decorative panels 1 and 2 has a stud bolt 6 corresponding to the through hole 10 b on the back surface side thereof, and the stud bolt 6 is attached to the decorative panel 1 or 2. After being inserted into the through hole 10b from the front surface side, the nut 5 is screwed into the rear surface of the side plate 10 via the washer 4 and tightened. At this time, a spacer 7 is interposed between the front surface of the side plate 10 and the back surface of the joint 3, and a similar through hole 7a is formed at a position corresponding to the through hole 10b in the spacer 7, for example. Insert the stud bolt 6 into 7a. The spacer 7 is thicker than the decorative panels 1 and 2, and a gap G is formed between the back surface of the joint 3 and the back surfaces of the decorative panels 1 and 2, but the gap G is aesthetically pleasing. It is desirable that the distance is about 0.1 mm to 1 mm. By forming this gap G, even if a slight vibration occurs due to the traveling of the elevator, friction does not occur between the rear surface of the joint 3 and the front surfaces of the decorative panels 1 and 2, and a squeak noise is generated. There is nothing to do.

Further, FIG. 2 is a cross-sectional view of the main part of the elevator car side wall having no drop joint 12 between the upright parts 10a and 11a of the side plates 10 and 11, but this case is also completely the same. The spacer 7 is interposed between the front surface of the side plate 10 and the rear surface of the joint 3, and the spacer 7 is thicker than the decorative panels 1 and 2, whereby the joint is A gap G is formed between the back surface of 3 and the back surfaces of the decorative panels 1 and 2. By forming this gap G, even if a slight vibration is generated by the traveling of the elevator, friction does not occur between the back surface of the joint 3 and the front surfaces of the decorative panels 1 and 2. The squeaking noise is not generated, and the same effect as that of the previous embodiment can be obtained.

In the above embodiment, the stud bolt 6 of the joint 3 is screwed with the nut 5 provided on the back surface of the side plate 10 to fix the joint 3 to the side plate 10. However, the joint 3 may be fixed by another structure. The present invention can be similarly applied to the side wall of the elevator car in which the vehicle is fixed to the side plate 10.

[0011]

[Effect of device]

 As described above, in the present invention, a spacer that is thicker than the decorative panel is provided between the back surface of the joint and the surface of the side plate, and a gap is formed between the back surface of the joint and the surface of the decorative panel. Even if a slight vibration occurs while the car is running, friction does not occur between the back surface of the joint and the surface of the decorative panel, so no squeaking noise is generated regardless of the joint material, and the quiet elevator You can get a basket.
