Description

  The present invention relates to an escalator including a protective body suitable for protecting a user (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 Has been proposed to prevent
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. When doing so, the passersby around the escalator will be harmed (here, the protector is often damaged from the base of the fixed part by a passenger's collision etc., and almost the whole 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 applied, and it is necessary to manufacture for each kind of balustrade, resulting in a high cost.
3) Maintainability: Since the closed side of the above document has a considerable length, it is not possible to secure a space for maintenance work of components around the handrail, particularly the illumination lamp. Therefore, there has been a demand for a solution in terms of safety, economy and maintenance.

  The present invention has been made in order to solve such problems, and it is possible to reduce the weight that is effective in terms of safety, and further, it is possible to provide an escalator facility that can be easily handled even when the balustrade type is different and is excellent in terms of maintenance space. 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. 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 an escalator comprising a body and a protective body composed of a front edge provided at the front end thereof, the lower end of the plate is positioned below the upper surface of the handrail, and the lower end of the front edge is The plate body is positioned below the lower end portion of the plate body, and is fixed to a longitudinal groove portion provided at the lower end portion of the front edge body so as to extend toward the balustrade panel side so as to close the horizontal interval. With occlusion Escalators, characterized in that it comprises a body.

  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. Characteristic escalator.

  According to the configuration of the first aspect, the occlusion body added in the present invention is a light-weight product reduced to about 1/10 of the weight of the conventional occlusion body, and even if it falls, it can protect the surrounding passersby. The degree of harm can be greatly reduced. In addition, the protective body of the present invention is configured to be easily fitted in the vertical groove portion provided at the lower end portion of the front edge body in the vertical direction, and after positioning is fixed by adhesion or the like to close the horizontal interval. Even models with different balustrade heights have the advantage of being able to adjust the height of the closure, thereby providing a safer and more economical escalator facility. 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. The protector 3 has a substantially triangular plate body 3C having a lower end 3B with an overlap ha below the upper surface of the handrail 1B, and a lower end 3B provided at the front end thereof. A round bar front edge body 3D having an overlap hb extending below the upper surface of the handrail 1B is provided. Further, a vertical groove portion 3a is provided at the lower end portion 3DD of the front edge body 3D, and the vertical groove portion 3a has a certain area with an adhesive or a screw (not shown) so as to close the horizontal interval m so as to close the balustrade panel 1C. A closing body 3E having a shape extending toward the side is provided. Here, the dimension of the balustrade height H differs by about 10 to 50 mm depending on the manufacturing time and the manufacturer, but in that case, it is moved in the vertical direction within the range of the vertical groove portion 3a at the installation site and is closed. This is a mechanism for fixing to the front edge body 3D by bonding or the like after determining an interval n which is a predetermined position in consideration of the safety and maintenance aspects of 3E. A swingable protector 6 is provided in front of the protector 3.

  In short, the protection body 3 of the present invention is fixed to the fixing body 2 with the front edge body 3D and the closing body 3E attached to the plate body 3C of the main member, and constitutes the escalator 1 of claim 1 as a whole. Yes. In addition, the closing body 3E 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 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 body 3E 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, compared to the conventional structure in which the closed side is integrated with the vertical side, the mounting position of the closed body 3E is flexible (adjustable in the vertical groove portion 3a), and the closed body 3E of the present invention has a small size. Therefore, in addition to being inexpensive, its weight is reduced to 1/10 or less of the conventional weight, so that the influence on the human body in the downstairs can be remarkably reduced even if an unexpected fall situation is assumed. The interval n is used as a maintenance space when the lighting lamp 1F is replaced.

  Here, the fixing structure of the front edge body 3D and the closing body 3E of the protective body 3 exemplified as the embodiment is not limited to adhesion, and may be any structure that can be attached at the installation site.

  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 realize an escalator excellent in safety, economy, and maintainability. it can.
