Abstract

<P>PROBLEM TO BE SOLVED: To provide a safety device of a passenger conveyer, having an effect of preventing projection of a screw fastening an inner deck cover and a skirt guard and having excellent appearance. <P>SOLUTION: This passenger conveyer includes: the inner deck cover 7 and the skirt guard 6. In order to prevent projection of a screw caused by looseness of the screw 11 fastening the inner deck cover 7 and the skirt guard 6, the safety device 10 formed of a scalene recessed groove is so constructed that a short side covering the screw head of the screw 11 is provided with a hole 10A for fastening the screw 11, and a long side is provided with an elongated hole 10B for inserting the screw 11. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to passenger conveyors such as escalators and electric roads, and more particularly to a safety device for preventing accidents between a step side and a railing.

  To install the skirt guard, it is fastened from the inner deck cover side with a common screw. Conventionally, in order to prevent the fixing screw from loosening and to prevent the screw head from protruding, the screw head is covered with glued aluminum tape or the like to prevent a screw protruding accident.

Problems to be solved by the invention

  The above prior art has a problem in repeated sticking strength and aesthetics associated with the attachment / detachment of the safety device, and there is a problem that improvement is required in terms of maintaining safety and dealing with time.

  An object of the present invention is to provide a safety device for a passenger conveyor that is excellent in safety, beauty and maintainability between a step and a skirt guard.

Means for solving the problem

  In order to achieve the above object, the present invention achieves the above-described endlessly connected step, a balustrade arranged upright on both sides of the step, a skirt guard constituting the balustrade, an inner deck cover, a balustrade panel, etc. In a passenger conveyor equipped with a skirt guard, a groove on the lower side of the inner deck cover that sandwiches the skirt guard and a screw insertion part that covers the screw head is provided in the lower side screw insertion part, and the screw head is placed on the short side. A safety device having a long hole longer than the short side is inserted to cover the long side for screw insertion.

  In the above configuration, the safety device is inserted from the lower side of the inner deck cover, screws are inserted and temporarily tightened from the upper part of the long side of the concave groove, and the safety device is shifted to the upper side. Furthermore, because it is configured to be tightened from a hole smaller than the screw head diameter provided on the short side that covers the screw head and the safety device is attached, the attachment strength of the skirt guard is high, and the skirt guard can be attached and detached very easily. Until the screw is pulled out, the screw shaft is inserted into the long hole of the safety device, and even if the screw is pulled out, the bottom side of the inner deck is sandwiched by the spring effect of the groove of the safety device. There is an advantage that it does not fall off, and the appearance of the safety device is not damaged and the aesthetic appearance is not impaired.

Hereinafter, one embodiment of a passenger conveyor safety device of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a passenger conveyor and its safety device according to the present invention, and FIG. 2 is a sectional view taken along line MM in FIG. 3 is a perspective view of the safety device, and FIG. 4 is a cross-sectional view taken along line NN in FIG. In the figure, an escalator-type passenger conveyor 1 is installed from the lower floor 2 to the upper floor (not shown), and is connected and moved endlessly from the entrance 3 to another entrance (not shown); A balustrade 5 arranged upright on both sides of the step 4, a skirt guard 6, an inner deck cover 7, a balustrade panel 8, a handrail 9 and the like constituting the balustrade 5 are provided. In order to prevent the screw head from protruding due to the looseness of the screws 11 holding the skirt guard 6 and the inner deck cover 7, a 10A hole into which the tip of the driver can be inserted is provided on the short side, and the screw 11 is provided on the long side. A grooved safety device 10 having an unequal side groove provided with a long hole 10B that can be inserted without touching is inserted from the lower part of the inner deck cover 7 between the skirt guard 6 and the inner deck cover 7, and a screw 11 is inserted into the long hole. 10B is inserted from the upper part, temporarily tightened, and the safety device 10 is moved to the upper part. The hole 10A is aligned with the center of the screw 11 and fixed. Since both ends of the short side cover the screw 11 as shown in FIG. 4, it is safe against a catching accident such as a footwear or clothes of a passenger. Furthermore, when the escalator is inspected, the skirt guard 6 must be attached. However, since the screw 11 can be attached without deforming the safety device, it is also effective in the inspection work.

The invention's effect

  As described above, according to the present invention, it is possible to obtain a passenger conveyor safety device that is excellent in the effect of preventing protrusion of a screw that fastens the inner deck cover and the skirt guard, and also in appearance.

It is a perspective view which shows a passenger conveyor and its safety device by the present invention. It is sectional drawing which follows the MM line | wire of FIG. 1 is a perspective view of a safety device according to the present invention. It is sectional drawing which follows the NN line | wire of FIG.
