A crank bar 3 made of steel provided with a short bracket 2 connected to the chain belt a has a long edge connected to the outer chain belt b running in the vertical continuous conveyance device at both ends at the rear edge. Crank bars 5 made of steel material provided with brackets 4 are respectively attached.
[0011]
Further, on the upper surface of the left and right side edge portions of the load receiving surface 1, wedge pieces 6 having the same shape that are in close contact with each other in the horizontal state of the load receiving surface 1 are arranged in a row.
[0012]
The load receiving surface 1 is made of a sheet material 7 such as a tough and flexible fabric such as a belt or a tent. Preferably, in order to enhance the load resistance of the load receiving surface 1, for example, as shown in FIG. Further, a core material 8 made of steel or hard synthetic resin is fixed in parallel with the crank bars 3 and 5 or, as shown in FIG. 8 is adhered by an adhesive or the like with a covering piece 9 made of cloth or the like.
[0013]
As a method of attaching the crank bars 3 and 5 to the front and rear edges of the load receiving surface 1, as shown in FIG. 6, in addition to adhesion, riveting or bolt / nut tightening, it is surrounded by the front and rear edges of the sheet material 7. As shown in FIG. 7, there is a method of fixing them integrally, or a method of sewing the front and rear edges of the sheet material 7 and the crank bars 3, 5 with the sewing thread 10. In the case of sewing with the sewing thread 10, The bars 3 and 5 are provided with holes 11 penetrating in the thick direction for inserting the pre-sewn thread.
[0014]
The wedge pieces 6 disposed on the left and right side edges of the load receiving surface 1 are preferably made of a material that relieves a collision sound and has hardness, and synthetic resin, wood, or the like is selected as the material.
[0015]
Specifically, a wedge piece made of urethane resin or polycarbonate resin effective for the silencing effect is used. As another form, as shown in FIG. 8, a square steel material 6a is made of a synthetic resin sheet having a high silencing effect. Alternatively, the wedge piece 6 may be configured by covering with an outer skin 6b such as leather, and as shown in FIG. 9, the wedge piece 6 is made of, for example, a steel material that does not have a silencing effect between the pieces. The wedge pieces 6c and the wedge pieces 6d made of a synthetic resin having a high silencing effect may be alternately arranged.
[0016]
The wedge pieces 6 to 6c and 6d arranged on the left and right side edges of the load receiving surface 1 are fixed by adhesion, riveting or bolt / nut tightening, but in addition, as in the case of the crank bars 3 and 5, As shown in FIG. 10, a sewing method using the sewing thread 10 is also employed.
