  A deflecting wheel 7 is attached to the machine base 3. A suspension means 8 is wound around the drive sheave 5 and the deflecting wheel 7. As the suspension means 8, for example, a plurality of ropes or a plurality of belts are used.

  A car 9 is connected to the first end of the suspension means 8. A counterweight 10 is connected to the second end of the suspension means 8. The car 9 and the counterweight 10 are suspended in the hoistway 1 by the suspension means 8 and move up and down in the hoistway 1 by the driving force of the hoisting machine 4.

  In the hoistway 1, a pair of car guide rails 11 that guide the raising and lowering of the car 9 and a pair of counterweight guide rails 12 that guide the raising and lowering of the counterweight 10 are installed.

  The car 9 has a car frame 13 to which the suspension means 8 is connected and a car room 14 supported by the car frame 13.

  FIG. 2 is a perspective view showing the car room 14 of FIG. The cab 14 includes a cab floor 21, a plurality of wall panels 22 as panel members standing side by side on the cab floor 21, and a cab ceiling 23 fixed on the wall panel 22. .

  Adjacent wall panels 22 are fastened together by a plurality of panel fasteners 24. The panel fasteners 24 are spaced apart from each other in the vertical direction. A lower reinforcing bracket 25 having a U-shaped cross section is fixed to the lower end of each wall panel 22. An upper reinforcing metal fitting 26 having a U-shaped cross section is fixed to the upper end portion of each wall panel 22.

  The wall panel 22 is fixed to the car floor 21 by inserting screws into a plurality of holes 25 a provided in the lower reinforcing bracket 25. The wall panel 22 is fixed to the cab ceiling 23 by inserting screws into a plurality of holes 26 a (FIG. 3) provided in the upper reinforcing bracket 26.

  3 is a perspective view showing a state before the wall panel 22 of FIG. 2 is fastened, and FIG. 4 is an enlarged side view of the panel fastener 24 of FIG. Here, one of the two wall panels 22 adjacent to the left and right is the first wall panel (first panel material) 221 and the other is the second wall panel (second panel material) 222. To do.

  Each wall panel 22 has a front part facing the inside of the cab 14 and a pair of side parts formed by bending both ends of the front part in the width direction at right angles. The side surface portion of the first wall panel 221 on the second wall panel 222 side is the first side surface portion 221a, and the side surface portion of the second wall panel 222 on the first wall panel 221 side is the second side surface portion. 222a.

  The panel fastener 24 fastens the first side surface portion 221a and the second side surface portion 222a. Further, the panel fastener 24 includes a small clip 31 as a first mounting portion mounted on the first side surface portion 221a and a large clip 32 as a second mounting portion mounted on the second side surface portion 222a. And a rivet 33 as a fixture for integrating the small clip 31 and the large clip 32.

  Each of the small clip 31 and the large clip 32 is formed by bending a flat (band-shaped) metal member into a W shape. Each panel fastener 24 is configured by integrating a small clip 31 and a large clip 32 with a rivet 33.

  The first side surface portion 221a is provided with a plurality of small clip insertion holes 221b as first mounting portion insertion holes into which the small clips 31 are inserted. The second side surface portion 222a is provided with a plurality of large clip insertion holes 222b as second mounting portion insertion holes into which the large clips 32 are inserted.

  The small clip 31 is a first fixed portion 31a having a U-shaped cross section and a first leaf spring portion whose interval is tapered from the front end to the rear end in the insertion direction into the small clip insertion hole 221b. It has a pair of 1st inclination part 31b, 31c. The first inclined portions 31b and 31c are elastically deformed when inserted into the small clip insertion hole 221b to allow passage through the small clip insertion hole 221b, and are restored after being inserted into the small clip insertion hole 221b. Is prevented from coming out of the small clip insertion hole 221b.

  The large clip 32 has a U-shaped second fixing portion 32a, and a second leaf spring portion whose interval extends in a tapered shape from the front end to the rear end in the insertion direction into the large clip insertion hole 222b. It has a pair of 2nd inclination parts 32b and 32c. The second inclined portions 32b and 32c are elastically deformed when inserted into the large clip insertion hole 222b to allow passage through the large clip insertion hole 222b, and are restored after being inserted into the large clip insertion hole 222b to be restored to the panel fastener 24. Is prevented from coming off from the large clip insertion hole 222b.

  When the first wall panel 221 and the second wall panel 222 are fastened, the small clip 31 is inserted into the small clip insertion hole 221b, and the panel fastener 24 is attached to the first side surface portion 221a. Then, the second wall panel 222 is moved in the width direction, and the large clip 32 is inserted into the large clip insertion hole 222b.

  FIG. 5 is a cross-sectional view of the panel fastener 24 in a state where the first and second wall panels 221 and 222 of FIG. 3 are fastened. Even if the plate thickness of the wall panels 221 and 222 to be fastened changes, the same panel fastener 24 can be applied because it is absorbed by the elastic deformation of the small clip 31 and the large clip 32.

  FIG. 6 is a cross-sectional view showing a state in the middle of removing the small clip 31 of FIG. 5 from the first side surface portion 221a. When releasing the fastening state of the first and second wall panels 221, 222, the first inclined portions 31b, 31c are compressed and elastically deformed in the directions of arrows A, B, and the small clip 31 is inserted into the small clip insertion hole 221b. Pull out in the direction of arrow C.

  In such an elevator cab 14, the second side wall 222a of the second wall panel 222 is provided with a large clip insertion hole 222b, and the panel fastener 24 is inserted into the large clip insertion hole 222b. A large clip 32 is provided, and the large clip 32 is provided with second inclined portions 32b and 32c. For this reason, only by moving the 1st and 2nd wall panels 221 and 222 to the width direction, it can be easily fastened by one touch without a tool, and installation workability | operativity can be improved.

Moreover, since the installation to the 1st side part 221a of the panel fastener 24 can be performed by one-touch without a tool, installation workability | operativity can be improved further.
Furthermore, since the panel fastener 24 can be removed without damaging the wall panel 22, the panel fastener 24 can be used in temporary assembly for design confirmation.

Further, when the wall panel 22 is fastened, it is not necessary to turn to the back of the wall panel 22, and the installation workability is further improved.
Furthermore, since it is not necessary to secure the space for fastening the wall panel 22 on the back side of the wall panel 22, the space on the back side of the cab 14 can be minimized, and the space of the elevator can be saved. it can.

  Moreover, since the panel fastener 24 can be easily retrofitted at the installation site, the panel fastener 24 is not added as a projection to the wall panel 22 when shipped from the factory. For this reason, it is not necessary to change the transportation and packing method, and the panel fastener 24 is prevented from being deformed by vibration during transportation.

In the above example, the small clip 31 and the large clip 32 are shown as the first and second mounting portions, but the sizes of the first and second mounting portions may be the same.
Moreover, a fixing tool is not limited to the rivet 33, For example, a welding part may be sufficient.
Furthermore, the shape of the first leaf spring portion is not limited to the first inclined portions 31b and 31c. Similarly, the shape of the second leaf spring portion is not limited to the second inclined portions 32b and 32c.
