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, it will be sandwiched when the passenger's upper body rides with the head lowered over the handrail to the balustrade deck side Proposal to prevent accidents,
1) Fall accident at the time of breakage: A heavy plate is added to the heavy plate (vertical side) and a closed side that is bent together with it is added. Damage to passersby around the escalator (where the protector is often damaged from the base of its fixed part due to passenger collision, etc., and it is known that almost the entire weight falls) .
2) Flexibility for mounting: Protective bodies such as the above document are escalators that have a limited and fixed positional relationship (dimension) between the vertical side and the closed side, and have different balustrade heights (handrail height positions). On the other hand, it cannot be commonly applied, and it is necessary to manufacture for each kind of balustrade, resulting in a problem of high cost.
3) Maintainability: Since the closed side of the above document has a considerable length, a space necessary for maintenance work of components around the handrail, in particular, an illumination lamp is not secured.
Therefore, there has been a demand for a solution in terms of safety, economy and maintenance.

  The present invention has been made to solve such problems, ensuring safety by maintaining strength effective in preventing fall accidents, and also being easy to handle even when the balustrade type is different and excellent in terms of maintenance space. The purpose is to provide escalator equipment.

  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. A substantially triangular plate in a wedge-shaped space formed by a balustrade composed of a balustrade panel forming a road, a balustrade deck, etc., and a fixed body such as a building ceiling adjacent to the handrail with a horizontal interval In the escalator provided with a protective body made of a body or the like, the wedge-shaped space is provided with a front edge column that is fixed to the fixed body and the outer deck and stands upright, while the lower end portion of the plate body is positioned above the upper surface of the handrail. The front edge column is fixed to the front edge column in a state of being positioned below, and is extended further toward the balustrade panel side so as to close the horizontal interval at a lower position than the plate body. Fixed to And the escalator, characterized in that it comprises a protective body made.

  Further, in order to achieve the above object, as described in claim 2, the closure body includes a protection body configured to be separated from the upper surface of the handrail by more than three times its thickness. The escalator is characterized by that.

  According to the configuration of the first aspect, the front edge column constituting a part of the protection body of the present invention is a sturdy structural column by being fixed to the fixed body and the outer deck, and the plate body added thereto Moreover, it can be said that the attachment strength of the obstructing body becomes strong, and it does not cause any harm to surrounding passersby by dropping them as usual. In addition, the closure body constituting a part of the protection body of the present invention can be attached to any part near the lower end of the front edge column, so that the height of the closure body can be adjusted even in models with different balustrade heights. Thus, a higher-strength and safe escalator facility can be provided. 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 work 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 the upper end is fixed to the wedge-shaped space Q which is located with a horizontal interval m between the handrail 1B and formed by a fixed body 2 such as a building ceiling having a different inclination angle from the handrail 1B. A front edge column 3 is fixed to the body 2 with a screw 3B via a metal fitting 3A, and its lower end is fixed to the outer deck 1D with a screw 3D via a metal fitting 3C. Further, the front edge column 3 is formed of a substantially triangular plate body 4 having a lower end portion 4A extending downward from the upper surface of the handrail 1B along the lower surface of the fixed body 2, and a bracket 4B and a screw 4C. On the other hand, the rear part thereof is fixed to the fixed body 2 by a metal fitting 4D and a screw 4E. Further, a plate that extends further downward than the lower end portion 4A of the plate body 4 and extends toward the balustrade panel 1C so as to close the horizontal interval m with an interval n below the upper surface of the handrail 1B. A closed body 5 is fixed to the front edge column 3 with screws 5A. Here, the dimension of the balustrade height H varies by about 10 to 50 mm depending on the production time and the manufacturer, but in that case, the closure body 5 is determined in consideration of the safety and maintenance aspects of the passenger at the installation site. This is a mechanism for fixing the front edge column 3 with a screw 5A after determining the interval n as a position. Thus, a swingable protector 7 is provided in front of the protector 6 of the present invention constituted by the front edge column 3, the plate body 4 and the closing body 5.

  In short, the protection body 6 of the present invention is fixed to the fixed body 2 and the outer deck 1D as a whole with the plate body 4 and the closing body 5 attached to the sturdy front edge column 3 as the main member. 1 escalator 1 is configured. In addition, the closure body 5 is located at a position lower than the upper surface of the handrail 1B by more than three times its thickness, that is, at a position lower than the illumination lamp 1F of the balustrade 1E, as a whole. The escalator 1 is configured.

  The protector 6 closes the vertical direction of the wedge-shaped space Q by the front edge column 3 and the plate body 4, and closes the horizontal interval m by the closing body 5 so that the upper body of the passenger passes the handrail 1B to the balustrade deck 1D side. Accidents that can be caught with the head down can also be prevented. In this case, compared with the conventional structure in which the closed side is integrated with the vertical side, the mounting and positioning of the closed body 5 is more flexible (can be adjusted up and down within a certain range of the front edge column 3), and the plate 4 of the present invention. And since the obstruction body 5 is securely fixed to the sturdy front edge column 3, there is no fear of dropping and there is no fear of causing harm to a downstairs passerby. Further, the interval n is utilized as a work space when replacing the bulb of the illumination lamp 1F, and is excellent in maintainability.

  Here, the fixing structure of the plate body 4 and the closing body 5 with respect to the front edge column 3 exemplified as the embodiment is not limited to metal fittings or screws, but may be based on adhesion or the like.

  As described above, according to the above-described embodiment, it is possible to provide a protector that can handle various escalators including a moving sidewalk regardless of the type of balustrade, and an escalator excellent in safety and maintainability can be realized.
