Description

The present invention relates to a skirt molding for a passenger conveyor used for a railing of a passenger conveyor such as an escalator or a moving walkway.

A passenger conveyor for passenger transportation, for example, an escalator, is configured by incorporating a step row for passenger transportation into a truss installed in a building. The step row is composed of a large number of steps connected in an endless manner, and balustrades are provided on both sides of the step row.

The escalator can transport passengers from the lower floor to the upper floor or from the upper floor to the lower floor by sequentially running each step from the lower floor to the upper floor or from the upper floor to the lower floor of the building.

A skirt guard is provided on the side of the step with a slight gap almost perpendicular to the step. The upper and lower portions of the skirt guard are supported by brackets provided so as to extend from the balustrade fixing member fixed to the truss. In addition, a balustrade panel is erected on the balustrade fixing member, and an inner deck is provided between the inner surface of the balustrade panel and the upper edge of the skirt guard so as to incline toward the step. There is. The upper edge of the inner deck is fixed to the inner surface of the balustrade panel via a joint member, and a bent portion projecting to the step side is formed on the lower side of the inner deck. The lower edge of the inner deck is overlaid on the skirt guard and secured to the bracket with screws.

Further, a skirt molding is attached where the lower edge of the inner deck and the skirt guard overlap. In this skirt molding, the screws that fix the bent part and the skirt guard provided on the lower side of the inner deck loosen during use and protrude to the step side so that they do not stick out to the step side and damage clothes etc. It is formed on the inside to cover the lower edge of the deck and the skirt guard fixing screw.

Further, this skirt molding is arranged on the skirt guard from the step side to the outside and is fixed by screws, and the screws are housed in the skirt molding. The skirt molding is provided with a groove for inserting the screw head over the entire area along the length direction of the skirt molding, and has a structure in which the screw can be slid from the end of the groove to the fixed position. .. Further, since the hole for fixing the screw has a shape that allows a tool to enter and is smaller than the screw head, the structure is such that the screw does not come off even if the screw is loosened during use.

However, in the case of the conventional configuration, the screw for fixing the skirt molding may slip and fall in the storage space of the skirt molding during the mounting work. In addition, it may take time to slide the screw along the groove to a fixed position and adjust the screw to the hole position.

Therefore, a technique for simplifying the work of fixing the skirt molding has been proposed (see Patent Document 1).
