A pair of handrails 22 and balustrade panels 23 are provided on the left and right sides of the passageway along the passageway.

The lower side portion (return portion) of the handrail 22 and the lower side portion of the balustrade panel 23 are shielded by the shielding portion 3 . The shielding part 3 is composed of a deck cover 30 , a skirt guard 31 , an exterior plate 32 and an inlet guard 33 . The deck cover 30 is arranged on the upper surface side and includes an inner deck cover 30A and an outer deck cover 30B. The skirt guard 31 is arranged on the side contacting the passage. The exterior plate 32 is arranged on the side opposite to the skirt guard 31 . The inlet guard 33 is arranged so as to cover both ends in the longitudinal direction (portions where the lower side portion (return portion) of the handrail 22 enters and exits). A pair of shielding portions 3 are provided on the left and right sides of the passage along the passage.

As shown in FIGS. 1 and 2, the inlet guard 33 is composed of a cover 34 that can be divided into left and right parts from the center. The cover 34 includes an inner cover 34A and an outer cover 34B. The inner cover 34A is curved or bent at the intermediate portion, and has a shape in which one end abuts one end of the outer cover 34B and the other end abuts the terminal end of the skirt guard 31. As shown in FIG. The outer cover 34B is curved or bent at an intermediate portion, and has a shape in which one end abuts one end of the inner cover 34A and the other end abuts the end of the exterior plate 32 . A front portion of the cover 34 serves as an inlet portion 35 . Note that the cover 34 is also called a newel cover, and the area in which the cover 34 is arranged is also called a newel portion. In this embodiment, the cover 34 is a molded resin product.

Inner cover 34A and outer cover 34B each include a notch 36 that opens at the butted ends. When the inner cover 34A and the outer cover 34B are combined, the two cutouts 36, 36 join together to form one oblong hole, which is the inlet 37 of the handrail 22 at the inlet section 35. As shown in FIG. That is, the inlet 37 is formed across the dividing line of the cover 34 that can be divided into left and right. In this embodiment, the notch 36 is rectangular, and the inlet 37 is oblong rectangular.

As shown in FIGS. 3 to 5, the inlet section 35 is provided with an inlet safety device 40 for the purpose of preventing entanglement and pinching. The inlet safety device 40 comprises an actuating body 41 and a safety switch 44 . The actuating body 41 is loosely fitted in the handrail 22 so that the tip side protrudes from the inlet 37 to the outside, and when it is pushed (retracted) into the inlet section 35 upon contact with the passenger's body or belongings, it is safe. Switch 44 is pressed. Safety switch 44 is a component of the safety circuit in escalator 1 . When the safety switch 44 is pressed and activated, a warning sound is emitted from a speaker (not shown) provided near the inlet portion 35, or the escalator 1 automatically stops.

The inlet safety device 40 includes an operating body 41 , a safety switch 44 , a movable base 42 and a fixed base 43 .

That is, the operating body 41 indirectly operates the safety switch 44 via the movable base 42 .

The mounting portion 42 a has an outer shape slightly larger than the inlet 37 when viewed from the moving direction of the movable base 42 . The surface of the attachment portion 42 a facing the outside is orthogonal to the moving direction of the movable base 42 and serves as the attachment surface of the operating body 41 . However, the mounting portion 42a has a handrail insertion hole 42b for inserting the handrail 22 therethrough. The handrail insertion hole 42b is opened by notching one side of the mounting portion 42a, more specifically, the side of the handrail 22 on the side where the open portion between the two ends is provided. This is to avoid interference with the balustrade panel 23 and to allow the movable base 42 to be easily removed from the handrail 22 . In this embodiment, the attachment portion 42a has a laterally long rectangular outer shape equivalent to the offset shape in which each side of the inlet 37 is offset outward. Further, in the present embodiment, the handrail insertion hole 42b has a laterally long oval cross-sectional shape that is the same as the offset shape in which the outer cross-sectional shape of the handrail 22 is offset outward.

The mounting surface of the mounting portion 42a has screw holes 42c at appropriate locations (four corners in this embodiment). The screw hole 42c is a hole for a screw 45 for fixing the operating body 41 to the mounting portion 42a.

A compression spring 46 as a biasing member is provided between the movable base 42 and the fixed base 43 . The compression spring 46 urges the movable base 42 in a direction away from the fixed base 43, that is, in a direction toward the outside. As a result, the tip side of the operating body 41 is normally maintained in a state of protruding outside from the inlet 37 .

The safety switch 44 is also called an inlet switch and is attached to the fixed base 43 . For the safety switch 44, various types of known actuators, such as lever types such as roller lever types and rod lever types, and plunger types such as roller plunger types and push plunger types, can be employed. In this embodiment, the safety switch 44 is a limit switch provided with a roller plunger type actuator 44a.

As shown in FIG. 6, the operating body 41 includes a tubular portion 41a and a flange portion 41b. The tubular portion 41a is a portion protruding from the inlet 37 to the outside. The flange portion 41 b is a portion attached to the attachment portion 42 a of the movable base 42 . The operating body 41 is a member made of a material such as rubber or hard resin that is deformable to some extent. The rubber-made operating body 41 is also called inlet guard rubber.

The tubular portion 41a has a flattened tubular shape whose height is smaller than its left and right widths corresponding to the cross-sectional shape of the handrail 22 . The flange portion 41b protrudes outward from the proximal end portion of the cylindrical portion 41a. A surface facing the inside of the flange portion 41 b (an end surface of the flange portion 41 b ) is perpendicular to the moving direction of the movable base 42 and serves as a mounting surface to the movable base 42 . The operating body 41 has a handrail insertion hole 41c for inserting the handrail 22 therethrough. The handrail insertion hole 41c is opened by cutting one side of the tubular portion 41a and the flange portion 41b, more specifically, the side of the handrail 22 on the side where the open portion between the two ends is notched with a width W. there is The width W is smaller than the lateral width of the handrail 22 . However, the operating body 41 has elasticity and can be deformed so that the width W increases. Thereby, the operating body 41 can be easily removed from the handrail 22 . In this embodiment, the flange portion 41b has a laterally long rectangular outer shape equal to the mounting surface of the mounting portion 42a of the movable base 42. As shown in FIG. In the present embodiment, the cylindrical portion 41a and the handrail insertion hole 41c have a laterally long oval cross-sectional shape that is the same as an offset shape in which the outer cross-sectional shape of the handrail 22 is offset outward.

The handrail insertion hole 41c has a step recess 41d. The step recess 41d is formed by recessing a portion of the handrail insertion hole 41c excluding the tip of the cylindrical portion 41a. As a result, the gap between the inner surface of the handrail insertion hole 41c (the surface facing the surface of the handrail 22) and the surface of the handrail 22 is widened by the step recess 41d.

The inlet safety device 40 comprises a handrail sanitizing device 5 . The handrail disinfecting device 5 is composed of an ultraviolet light source 50 and an operating body 41 . In this embodiment, the ultraviolet light source 50 is an ultraviolet LED (UV-LED) that emits deep ultraviolet light with a peak wavelength in the range of 100 nm to 280 nm.

The ultraviolet light source 50 is provided in the handrail insertion hole 41c. A plurality of ultraviolet light sources 50 are provided at predetermined intervals in the circumferential direction of the handrail insertion hole 41c. The ultraviolet light source 50 is provided in the step recess 41d of the handrail insertion hole 41c. More specifically, the ultraviolet light source 50 is embedded in the stepped recess 41d so that the emission surface is exposed to the inner surface of the stepped recess 41d. In this embodiment, the exit surface of the ultraviolet light source 50 is flush with the inner surface of the step recess 41d.

By the way, the return path portion of the handrail 22 is supported by a handrail guide 24 inserted inside the handrail 22 . On the other hand, the working body 41 is supported by the frame 10 via the movable base 42 and the fixed base 43 . Both the handrail guide 24 and the frame 10 are immovably fixed. Therefore, the handrail 22 and the handrail sterilization device 5 are relatively positioned in the direction (the width direction and the vertical direction) perpendicular to the moving direction of the handrail 22 . Thereby, the distance between the surface of the handrail 22 and the ultraviolet light source 50 is stably maintained. In this regard, the handrail sanitizer 5 includes a handrail guide 24 as a positioning means that defines the relative positional relationship between the UV source 50 and the surface of the handrail 22 .

As described above, according to the handrail sterilization device 5 according to the present embodiment, the ultraviolet light source 50 is within a certain distance even at the curved surface portion such as the side portion 22b of the handrail 22 or the folded end portion 22c. will be placed.

It can be done easily and quickly.

It should be noted that the present invention is not limited to the above embodiments, and various modifications can be made without departing from the gist of the present invention.

In the above-described embodiment, the ultraviolet light sources 50 are provided at regular intervals in the circumferential direction of the handrail insertion hole 41c of the operating body 41 . However, the invention is not limited to this. The UV sources may be provided at uneven intervals. For example, as shown in FIG. 8A, the ultraviolet light source 50 is arranged such that the portion of the handrail insertion hole 41c corresponding to the central portion 22a of the handrail 22 is dense, and the left and right side portions 22b, 22b of the handrail 22 are closed. And the portions corresponding to the left and right folded ends 22c, 22c can be arranged so as to be sparse. Thereby, the distribution of the amount of irradiation light can be made uniform.

In the above-described embodiment, the ultraviolet light source 50 is provided at portions of the handrail insertion hole 41c of the operating body 41 corresponding to the center portion 22a, the side portions 22b, and the folded end portion 22c of the handrail 22. As shown in FIG. However, it is considered that the frequency with which the passenger touches the folded end portion 22c of the handrail 22 is not high. In such a case, as shown in FIG. 8(b), the ultraviolet light source 50 may be provided at portions corresponding to the central portion 22a and the side portions 22b of the handrail 22, except for the folded end portion 22c. good. Alternatively, the ultraviolet light source 50 may be provided only on a portion of the handrail 22 corresponding to the central portion 22a.

Further, in the above embodiment, the ultraviolet light source 50 is embedded in the handrail insertion hole 41 c of the operating body 41 . However, the invention is not limited to this. The UV light source can be provided in a variety of forms, one example of which is described below.

The example shown in FIG. 9 is an example using a flexible substrate 53 . The flexible substrate 53 has an elongated band shape, is flexible to be bent, and constitutes the circuit substrate of the ultraviolet light source 50 . A plurality of ultraviolet light sources 50 are mounted on one surface of the flexible substrate 53 at predetermined intervals in the longitudinal direction of the flexible substrate 53 .

The handrail insertion hole 41c of the operating body 41 has a groove 41e instead of the stepped recess 41d as a recess along the circumferential direction of the handrail insertion hole 41c that widens the gap from the surface of the handrail 22 . The groove portion 41e is formed so that the flexible substrate 53 surrounds the handrail 22 with one surface facing inward, and the flexible substrate 53 matches the offset shape in which the outer cross-sectional shape of the handrail 22 is offset outward. The flexible substrate 53 is bent and supported. At each end of the groove portion 41e, a closing portion 41f for closing the end portion of the groove portion 41e is provided as a locking portion for locking the end portion of the flexible substrate 53. As shown in FIG.

The flexible substrate 53 is arranged along the bottom surface of the groove portion 41e so that the other surface faces the bottom surface of the groove portion 41e. The flexible substrate 53 is fixed to the bottom surface of the groove portion 41e by a known fixing means such as a screw, an adhesive, or an adhesive. However, the flexible substrate 53 can be attached to and detached from the groove 41e by releasing the fixing means.

According to this example, the actuating body 41 need only have the groove 41e and need not embed the ultraviolet light source 50 therein. The arrangement and quantity of the ultraviolet light sources 50 can be appropriately set with respect to the flexible substrate 53 .

Although not shown, the cord 51 extending from the flexible substrate 53 is passed through a part of the handrail insertion hole 41c of the operating body 41 between the side wall surface of the groove portion 41e and the end surface of the flange portion 41b. A groove is formed. This eliminates the risk of the cord 51 contacting the handrail 22 .

The example shown in FIG. 10 is an example in which a flexible substrate 53 on which an ultraviolet light source 50 is mounted is insert-molded into the cylindrical portion 41 a of the operating body 41 . Of course, the insert molding is performed so that the emission surface of the ultraviolet light source 50 is exposed to the inner surface of the handrail insertion hole 41c of the operating body 41. As shown in FIG.

According to this example, the ultraviolet light source 50 and the flexible substrate 53 are embedded in the tubular portion 41a of the working body 41 in a watertight manner. Therefore, it has improved water resistance and is suitable for escalators installed outdoors.

Further, in the above embodiment, the safety switch 44 of the inlet safety device 40 is operated via the movable base 42 . However, the invention is not limited to this. For example, it may be a form of inlet safety device in which the actuator directly actuates the safety switch by directly contacting the actuator of the safety switch.

Further, in the above-described embodiment, the operating body 41 is composed of the tubular portion 41a and the flange portion 41b. However, in the present invention, the flange portion is not essential.

Further, in the above embodiment, the inlet (gateway) 37 has a shape slightly smaller than the outer shape of the flange portion 41 of the operating body 41 . However, the invention is not limited to this. The inlet may be shaped to be larger than the flange portion of the effector, ie, the largest dimension of the effector. In this case, the process of "i) separating the cover 34 of the inlet guard 33 into left and right parts and removing" is not required, and maintenance work such as inspection and replacement can be performed more easily and quickly.

"Rectangular", "Oval", "End", "Center", "Middle", "Side", "Orthogonal", "Equal", "Flush", "Equidistant", " In the present invention, the term "homogeneous" that specifies a shape, part, or state includes not only that but also the concept of "substantially" meaning that it is close to or similar to it.

Also, in the above embodiments, the passenger conveyor is an escalator. However, it goes without saying that the present invention is also applicable to moving walkways.
