Abstract

PROBLEM TO BE SOLVED: To solve such problems of a conventional protector for an escalator that it is heavy in weight, and thus, in case it falls by any chance, it may injure a passer downstairs, that it is high in cost, and that maintainability is poor in replacement of lighting fixure, etc.SOLUTION: The protector 3 of the escalator 1 includes a roughly triangular plate 3C for closing a dangerous wedge-shaped space Q, a front edge body 3D for protecting a colliding object, and a small-sized blocking part 3DD provided at the lower end thereof to prevent a head of a passenger from entering.

Description

  The present invention relates to an escalator including a protective body suitable for protecting a user's head in a wedge-shaped space formed between a handrail of an escalator commonly called a moving sidewalk and a fixed body such as a building ceiling. .

  As a background art in this technical field, there is JP-A-2009-190893 (Patent Document 1). This gazette states that it is “an integral protector having a closed side that is L-shaped with a vertical side”.

JP 2009-190893 A

  The protector disclosed in the above-mentioned document 1 is provided on the upper ends of the balustrade on both sides of the escalator, and is formed of a handrail that moves in the upward direction and a fixed body (obstacle) such as a building ceiling adjacent to the handrail. By installing a protective body, commonly called `` triangular guard plate '', made of acrylic resin in the space, a passenger is trapped when the upper body of the passenger goes over the handrail and heads down to the railing deck side Although it is proposed to prevent a heavy plate, the obstructed side that is bent together with the plate (vertical side), which is a heavy object, is added, resulting in considerable weight, which should be damaged. If it falls, it will harm the passersby around the escalator. (Here, the protector is often damaged from the base of its fixed part by the collision of passengers, etc., and almost all the weight has dropped.) U). Further, since the closed side of the above document has a considerable length, a space for maintenance work of components around the handrail, in particular, an illumination lamp cannot be secured. There are safety, economic and maintenance problems that have been solved.

  The present invention has been made in order to solve such problems, and can be reduced in weight that is effective in terms of safety, can further secure a space necessary for replacement work of an illumination lamp, and is excellent in terms of maintenance. The purpose is to provide.

  In order to achieve the above object, the present invention provides a step of moving the endlessly connected horizontal road and ramp, a handrail serving as a handrail for this step, and a guide for this handrail. In a wedge-shaped space formed by a balustrade composed of a balustrade panel, a balustrade deck, etc. that forms a road, and a fixed body such as a building ceiling that is adjacent to the handrail with a horizontal interval, a substantially triangular vertical In an escalator comprising a protective plate made of a vertical plate and a vertical leading edge provided at the front end thereof, the lower plate of the protective plate and the lower edge of the front edge are positioned below the upper surface of the handrail. In addition, the escalator is provided with a protection body in which a lower end portion of the front edge body is extended at a right angle toward the balustrade panel side to form a closed portion that closes the horizontal interval.

  Further, in order to achieve the above object, as the escalator provided with a protector having a configuration in which the blocking portion is located at least three times lower than the thickness of the upper surface of the handrail. Yes.

  According to the configuration of the first aspect, since the closed portion added in the present invention is a lightweight product whose weight is reduced to 1/10 or less compared to the conventional closed body, even if it should fall, it will pass through the periphery. The degree of harm to humans can be greatly reduced. Further, the protective body of the present invention is formed with a closed portion for preventing the passenger's head from entering by bending the lower end portion of the front edge body at a right angle, thereby making the escalator equipment safer and more economical. Can provide. Furthermore, according to the configuration of claim 2, it is possible to provide an escalator facility that is effective in terms of maintenance, such as securing a maintenance space around the handrail, particularly for inspection and replacement of the illumination lamp.

It is a side view of the principal part which shows embodiment of this invention. It is sectional drawing which follows the AA line of FIG. It is a left perspective view showing an embodiment of the present invention.

  Hereinafter, an embodiment of an escalator provided with a protector according to the present invention will be described with reference to FIGS.

  In the figure, the escalator 1 has a large number of steps 1A that move endlessly connected to a ramp from a horizontal road with a boarding gate, a handrail 1B that serves as a handrail for this step 1A, and a guideway for this handrail 1B. A balustrade 1E having a height H (FIG. 2), which includes a balustrade panel 1C and a balustrade deck 1D to be formed, is provided. And in the wedge-shaped space Q formed by the fixed body 2 such as a building ceiling which is located with a horizontal interval m between the handrail 1B and has a different inclination angle from the handrail 1B, the upper end portion 3A thereof is formed. A protective body 3 is provided that is fixed to the fixed body 2 with screws 5 via metal fittings 4. Further, the protector 3 has a substantially triangular vertical plate 3C having a lower end portion 3B having an overlap ha below the upper surface of the handrail 1B, and a front end portion of the protector 3, which is lower than the lower end portion 3B. Further, there is provided a vertical front edge 3D of a round bar that extends downward and has an overlap n below the upper surface of the handrail 1B. Further, a closing portion 3DD formed by bending the front edge body 3D at a right angle is integrally provided at the lower end portion of the front edge body 3D, and this extends toward the balustrade panel 1C so as to close the horizontal interval m. It is configured to prevent the passenger head from entering. A swingable protector 6 is provided in front of the protector 3.

  In short, the protector 3 of the present invention is fixed to the fixed body 2 as a whole with the front edge body 3D and the closing portion 3DD integral with the front edge body 3D attached to the plate body 3C of the main member, as a whole. 1 is configured. In addition, the blocking portion 3DD is located at a position lower than the upper surface of the handrail 1B by more than three times its thickness, that is, at an interval n lower than the illumination lamp 1F of the balustrade 1E as a whole. The escalator 1 is configured.

  The protector 3 closes the vertical direction of the wedge-shaped space Q by the plate body 3C and the front edge body 3D, and closes the horizontal interval m by the closing portion 3DD so that the upper body of the passenger passes over the handrail 1B to the balustrade deck 1D side. Accidents can be prevented when the head is lowered. In this case, the closed portion 3DD of the present invention is small in size compared with a structure that is a closed side integral with a conventional plate body, and is therefore inexpensive, and its weight is reduced to 1/10 or less of the conventional weight. Even in the unlikely event of a fall, the danger to the human body downstairs can be greatly reduced. Further, the interval n between the blocking portions 3DD is used as a maintenance space when the illumination lamp 1F is replaced by a broken ball.

  Here, the connection structure of the front edge body 3D and the blocking portion 3DD of the protector 3 exemplified as the embodiment is not limited to the illustrated integrated product, and there is a problem even if the two members are joined by bonding or the like. There is no. Further, as shown by an imaginary line in FIG. 3, it is possible to increase the strength by connecting the plate 3C and the blocking portion 3DD with the reinforcing plate 3d.

  As described above, according to the above embodiment, a protector for various escalators including a moving sidewalk can be provided, and an escalator excellent in safety, economy, and maintainability can be realized.
