Abstract
Provided is the step of a passenger conveyor, wherein the shearing force applied on the fixing screw of a kick board lateral end boundary can be reduced. The step (14) is provided with an antiskid plate (18) for passengers to stand on, and kick board parts used for covering the height difference between adjacent steps. Each kick board part comprises a kick board, kick board lateral end boundaries (21) arranged on the left and right end portions of the kick board, and kick board bases (22, 23) used for installing the kick board and the kick board lateral end boundaries. The kick board lateral end boundaries are fixed to the kick board bases through fixing screws. The kick board lateral end boundaries are provided with engaging portions used for being engaged with the kick board bases and bearing the force in the up-and-down direction, such as clamping portions (25).
Description
Technical field
The present invention relates to the apparatus of passenger conveyor of escalator etc., especially relate to the structure of the kickplate side boundary member (Demarcation) of the left and right end portions that is arranged on step riser.
Background technology
In general,, in the apparatus of passenger conveyor of escalator etc., step connects into ring-type to carry out loopy moving between floor, gangway, is provided with the kickplate for covering the difference of height part producing between adjacent step on step.In existing kickplate, as shown in Figure 9, upper and lower (top and the bottom) at step 14a are provided with kickplate pedestal 22a, 23a, kickplate is fixed by welding on kickplate pedestal 22a, 23a conventionally, in order to cause that passenger notes, be provided with the resinous kickplate side boundary member 21a that is coated with the colors such as yellow in the left and right end portions of kickplate, this kickplate side boundary member 21a is fixed on kickplate pedestal 22a, 23a by fix screw 24a.
; foreign matter has for example occurred to be clipped under the state between kickplate side boundary member 21a and the checkered plate of rear step by the situation of R part; or when situation that the heel that passenger has occurred contacts with kickplate etc.; there is very large masterpiece to be used on kickplate side boundary member 21a; in existing technology; because relying on fix screw 24a, kickplate side boundary member 21a is fixed, so the masterpiece of shear direction is used on fix screw 24a.In the situation that bearing this shearing force by fix screw 24a completely, may cause fix screw 24a to fracture.Just in case while having there is situation that fix screw 24a fractureed, kickplate side boundary member 21a comes off, and the opening portion of step exposes, passenger's shoes and umbrella etc. may be involved in this opening portion, thereby large accident may occur.Therefore,, from guaranteeing safe angle, need to prevent effectively that kickplate side boundary member from coming off.

Detailed description of the invention
The embodiment of the stair device referring to accompanying drawing to apparatus of passenger conveyor involved in the present invention describes.
As shown in Figure 1, apparatus of passenger conveyor (for example escalator 1) has: the framework 4 arranging across upper floor 2 and the bottom floor 3 of building structure, be arranged on Machine Room, top 5 and the Machine Room, bottom 6 of the length direction two end portions of this framework 4, cover above-mentioned Machine Room 5 from top, 6 floor, gangway, top 7 and floor, gangway, bottom 8, be arranged on Machine Room 5, the upper terminal sprocket wheel 9 that is configured to respectively pair of right and left and lower terminal end sprocket wheel 10 in 6, be wound in the form of a ring above-mentioned terminal sprocket wheel 9, the step chain 11 of the pair of right and left on 10, connect the step axle 12 of the step chain 11 of left and right, be arranged on the front-wheel 13 at step axle 12 two ends, be rotatably installed in the step 14 on step axle 12, be arranged on and pass through terminal sprocket wheel 9 in Machine Room, top 5, 10 and step chain 11 actuating device 15 that step 14 is rotated, relatively erect the railing panel 16 that is arranged in framework 4 and periphery and synchronously driven moving hand-rail 17 of step 14 along this railing panel 16 to ground in the both sides of step along the moving direction of step 14.
As shown in the front elevation of Fig. 2, step 14 has the checkered plate 18 of standing for passenger and for covering the kickplate part 19 of the difference of height part producing between adjacent step.
Kickplate part 19 comprises kickplate 20, be arranged on this kickplate 20 left and right end portions kickplate side boundary member 21 and as shown in the lateral plan of Fig. 3, be separately positioned on step 14 top and the bottom for the kickplate pedestal 22,23 of kickplate 20 and kickplate side boundary member 21 is installed.
Kickplate side boundary member 21 is fixed on kickplate pedestal 22,23 by fix screw 24.
In the step of the apparatus of passenger conveyor of the present embodiment, on kickplate side boundary member 21, be provided with and engage with kickplate pedestal 22,23 and bear the snap portions that acts on the power on above-below direction.That is to say, on kickplate side boundary member 21, be formed with protuberance 25, this protuberance 25 is formed the above-below direction end butt of its side and upper and lower kickplate pedestal 22,23.
In the present embodiment, as shown in Figure 4, for example there is foreign matter A (the such as foreign matter such as footwear or umbrella) to be clipped under the state between kickplate side boundary member 21a and the checkered plate 18 of rear step 14 of front step 14 at centre portion, in the time of the R part by upper and lower, in the direction that fix screw 24 is sheared, there is larger masterpiece to be used on kickplate side boundary member 21.Therefore, form protuberance 25 at kickplate side boundary member 21, and the above-below direction end that makes upper and lower kickplate pedestal 22,23 respectively with these protuberance 25 butts, make to bear by this protuberance 25 power acting on kickplate side boundary member 21, to avoid the masterpiece of shear direction to be used on fix screw 24.
According to the present embodiment, can the shearing force of reducing effect on fix screw 24, can prevent that fix screw 24 from being fractureed, thereby can improve the safety of apparatus of passenger conveyor.
Other embodiment of stair device referring to Fig. 5 to Fig. 8 to apparatus of passenger conveyor involved in the present invention describes.
In the stair device of this other embodiment, as shown in Figure 5, on kickplate side boundary member 21, be provided with outshot 26,27 that section is L font as described snap portions, and the above-below direction end of upper and lower kickplate pedestal 22,23 is embedded in this outshot 26,27.
In this other embodiment, the downside end of the kickplate pedestal 22 of upside is embedded into by the back side of kickplate side boundary member 21 and section and is in the recess that the outshot 26 of L font forms, and the upper side end of the kickplate pedestal 23 of downside is embedded by the back side of kickplate side boundary member 21 and section and is in the recess that the outshot 27 of L font forms, make the power of being born towards the shear direction of fix screw 24 by outshot 26,27.In addition, in this structure, even in the situation that fix screw 24 contingency are fractureed, because the above-below direction end of kickplate pedestal 22,23 is supported in three directions respectively, so kickplate side boundary member 21 also can not come off in the time that step 14 overturns.That is to say, as show as shown in Fig. 6 of flip portion (R part) of apparatus of passenger conveyor, the step 14 of loop connecting overturns between the b of a He Fan road, outlet, while travelling on a of outlet, shown in the enlarged drawing of the B part of Fig. 6 as shown in Figure 7, kickplate side boundary member 21 is fastened togather via outshot 27 and kickplate pedestal 23, while travelling on the b of Er Fan road, shown in the enlarged drawing of the C part of Fig. 6 as shown in Figure 8, kickplate side boundary member 21 is fastened togather via outshot 26 and kickplate pedestal 22, even so when effect has the downward deadweight shown in arrow, kickplate side boundary member 21 also can not come off.
According to this other embodiment, can the shearing force of reducing effect on fix screw 24, can prevent that fix screw 24 from being fractureed, and, even in the situation that fix screw 24 contingency are fractureed, also can prevent that kickplate side boundary member 21 from coming off, thus the safety that can improve apparatus of passenger conveyor.
