Summary of the Invention
Problems to be Solved by the Invention
[0005] However, since the escalator belt disinfecting and cleaning machine described in Patent Document 1 has a large disinfectant storage tank installed in the main body, it has been a large-sized disinfecting and cleaning machine. Further, although the water drains are formed of a hard material such as rubber or plastic, the long escalator belt has undulations due to aging, and in many cases, the surface of the belt passing through the water drains does not maintain a constant shape, and only a part of the tip of the water drain comes into contact with the surface of the belt, resulting in uneven wiping of the disinfectant.
[0006] The present invention solves the above-mentioned conventional problems, and an object thereof is to provide a cleaning device for a handrail that can reduce the size of the device and prevent uneven wiping of the liquid to be applied.
Means for Solving the Problems
[0007] In order to solve the above-mentioned conventional problems, the invention according to claim 1 is a cleaning device for a handrail, which includes fixing means fixed to a guide rail for guiding the handrail, and a cleaning device main body for cleaning, washing or disinfecting the handrail. The cleaning device main body includes a housing, an application means disposed in the housing and contacting the surface of the handrail to apply a liquid, a wiping means disposed in the housing and contacting the surface of the handrail to wipe the liquid, and a liquid supply means disposed in the housing and supplying the liquid to the application means. The wiping means is formed of a plurality of pad members having liquid absorption performance. In a state of contacting the surface of the handrail, the tip portions of the adjacent pad members continuously overlap, and the central portions of the adjacent pad members have gaps.
[0008] According to the invention of claim 1, since the cleaning device main body has an application means, a wiping means, and a liquid supply means in the housing, the size of the cleaning device for the handrail can be reduced. Further, the wiping means is formed of a plurality of pad members having liquid absorption performance. In a state of contacting the surface of the handrail, the tip portions of the adjacent pad members continuously overlap, so that the strength of the pad members can be enhanced, the handrail can be strongly contacted, and uneven wiping of the liquid can be prevented. Further, since the central portions of the adjacent pad members have gaps, the volatilization effect of the liquid absorbed by the pads can be enhanced, and the liquid absorption performance of the tip portions of the pad members can be maintained even after long-term use. Further, the gaps in the central portions function so that the pad members can be bent, and the impact force from the handrail with undulations can be released by the bending of the pad members, and the influence of the impact force on the entire cleaning device can be mitigated.
[0009] The invention according to claim 2 is characterized in that, in the invention according to claim 1, the wiping means is such that the base portions of adjacent pad members are integrally welded and fixed. Thereby, since a base made of metal or resin is not required, the manufacturing cost can be reduced and the labor for decomposition at the time of disposal can be eliminated.
[0010] The invention according to claim 3 is characterized in that, in the invention according to claim 1 or 2, the wiping means connects and fixes the base portions of the respective pad members with a substantially plate-shaped substrate, and a drainage hole is formed at substantially the center of the substrate. Thereby, it is possible to suppress the accumulation of liquid at the base portions of the pad members and maintain the volatilization effect of the pad members.
[0011] The invention according to claim 4 is characterized in that, in the invention according to any one of claims 1 to 3, the wiping means has a desiccant disposed in the gap at the center of adjacent pad members. Thereby, the volatilization effect of the pad members can be further enhanced.
Effect of the Invention
[0015] The invention according to claim 1 can miniaturize the cleaning device for the handrail and prevent uneven wiping of the liquid. In addition, the volatilization effect of the liquid absorbed by the pad can be enhanced, and the liquid absorption performance of the tip portion of the pad member can be maintained even after long-term use. Further, the gap at the center can relieve the impact force on the entire cleaning device. The invention according to claim 2 can reduce the manufacturing cost and eliminate the labor for decomposition at the time of disposal. The invention according to claim 3 can maintain the volatilization effect of the pad members.
[0016] The invention according to claim 4 can enhance the volatilization effect of the pad members.

Embodiments for Carrying Out the Invention
[0018] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited by this embodiment. Fig. 1 is a perspective view showing the cleaning device for a moving handrail according to the present invention. Also, Fig. 2(a) is an exploded perspective view showing the cleaning device for a moving handrail according to the present invention, and Fig. 2(b) is an exploded perspective view showing the cleaning unit that constitutes the cleaning device for a moving handrail according to the present invention. The outline of the cleaning device for a moving handrail according to the present invention will be described below using these figures.
[0019] As shown in Fig. 1, the cleaning device 30 for a moving handrail has a fixing means 20 fixed to a guide rail for guiding the moving handrail, and a cleaning device main body 10 for cleaning, washing, or disinfecting the moving handrail. The fixing means 20 is formed with a front restraint member 20a at the front opening through which the moving handrail passes to prevent a child from accidentally inserting their hand, and a rear restraint member 20b is similarly formed at the rear opening. And the cleaning device main body 10 is detachably attached to the fixing means 20.
[0020] The cleaning device main body 10 has a housing 1 and a cleaning unit 5 disposed within the housing 1. The housing 1 includes a housing main body 7 having an opening 7a and a lid 8 for opening and closing the opening 7a. Further, the cleaning unit 5 includes an application means 2 that abuts against the surface of the handrail for movement and applies a liquid, a wiping means 3 that abuts against the surface of the handrail for movement and wipes off the liquid, a liquid supply means 4 that supplies the liquid to the application means 2, and a cleaning means 6 that abuts against the surface of the handrail for movement and removes dirt.
[0021] And the cleaning unit 5 is detachably attached to the housing 1. Specifically, the plate 5a constituting the cleaning unit 5 is detachably attached to the lid 8 constituting the housing 1.
[0022] The lid 8 is formed in a substantially flat plate shape or a substantially cup shape, and one end of the lid 8 is rotatably connected to the housing main body 7 via a hinge 7b. Further, a protective member 8a is formed on the outer surface of the lid 8. If the protective member 8a is formed at a position where the lid 8 hits the floor surface during the opening operation of the lid 8, damage to the lid 8 can be prevented. Further, the protective member 8a can protect the built-in cleaning unit 5 by alleviating the impact when a user of the escalator accidentally kicks the lid 8 or a suitcase hits it.
[0023] In addition, the shape of the lid 8 may be changed from a substantially cup shape to a substantially flat plate shape, and the plate 5a constituting the cleaning unit 5 may be detachably attached to the housing main body 7 constituting the housing 1, and this is also included in the present invention. Further, the case where the lid 8 slides with respect to the housing main body 7 to open and close is also included in the present invention.
[0024] Further, as shown in Fig. 2(b), in the cleaning unit 5, a cleaning means 6, an application means 2, a wiping means 3, and a liquid supply means 4 are each detachably attached to a plate 5a constituting the cleaning unit 5. Note that the cleaning unit 5 constituting the present invention is also included in the present invention even when it does not have the plate 5a as a separate body. For example, the present invention also includes a case where the cleaning means 6, the application means 2, and the wiping means 4 are each detachably attached to a member in which the liquid supply means 4 and the plate 5a are integrated.
[0025] The cleaning means 6 has a plurality of brush hairs 6a attached to a base 6b, and a convex portion 6c that fits into a concave portion 5b formed in the plate 5a is formed on the base 6b. Thereby, the cleaning means 6 is detachably attached to the cleaning unit 5. Note that instead of the brush hairs 6a, microfibers, cloth, sponge, or inclined pile can also be used, and this is also included in the present invention.
[0026] The application means 2 is formed by coupling a liquid-absorbing function cloth 2a on the side inserted into the insertion port A of a cup filled with the liquid constituting the liquid supply means 4 and a non-woven fabric pad 2b on the side contacting the moving handrail via an attachment member 2c. The non-woven fabric pad 2b has a concave portion 2e formed so as to correspond to the shape of the moving handrail, and a plurality of slits 2f are formed so that the concave portion 2e can be deformed. Then, the attachment member 2c is fitted into a locking frame 5c formed in the plate 5a, and a locking groove (not shown) formed on the inner peripheral surface of the attachment member 2c and a locking claw 5g formed on the outer peripheral surface of the insertion port A of the liquid supply means 4 are locked. Thereby, the application means 2 is detachably attached to the cleaning unit 5.
[0027] The liquid supply means 4 has a hollow cup body 4a, in which an insertion port A and a liquid replenishment port B are formed. The liquid replenishment port B is an opening for replenishing liquid, and a cap 4b is fitted to the liquid replenishment port B. A cloth 2a having the liquid absorption function of the coating means 2 described above is inserted into the insertion port A, and the tip of the cloth 2a having the liquid absorption function reaches the bottom inside the cup body 4a. Thus, all the liquid inside the liquid supply means can be sucked up by the coating means 2. Further, fitting projections 4c are formed at two locations on the outer surface of the cup body 4a, and the fitting projections 4c are configured to be fitted into the fitting holes 5d of the plate 5a. Thus, the liquid supply means 4 is detachably attached to the cleaning unit 5.
[0028] The wiping means 3 has pad members 3b, 3b,... each composed of a plurality of flat non-woven fabrics having liquid absorption performance, which are attached to a substrate 3a. Concave contact portions 3c are formed in the pad members 3b, 3b,.... Further, the pad length of the pad member 3b is formed such that the downstream side is longer than the upstream side of the moving handrail, and the pad member 3b is formed to contact the moving handrail while being inclined downstream. Thus, the area of contact between the pad member 3b and the moving handrail can be increased, and wiping can be performed efficiently. Further, a gap 3d is formed between adjacent pad members 3b, 3b, and three or more pad members 3b, 3b,... having liquid absorption performance are arranged at equal intervals. Thus, the liquid absorption performance can be improved, and by making the gap 3d at the center of adjacent pad members 3b an optimal width, an increase in the size of the wiping means 3 can be prevented. Note that the material of the wiping member 3 is not limited to non-woven fabric, and various materials can be selected as long as they have liquid absorption performance, and this is also included in the present invention.
[0029] Further, one end of the substrate 3a is fitted into the locking hooks 5e, 5e of the plate 5a, and a locking piece (not shown) is formed on the side surface of the substrate 3a, and this locking piece is configured to be locked in a locking hole 5f formed in the plate 5a. Thus, the wiping means 3 is detachably attached to the cleaning unit 5.
[0030] Figure 3(a) is a cross-sectional view showing the state in which the cleaning device for a moving handrail according to the present invention is fixed to an escalator, and Figure 3(b) is a partially enlarged cross-sectional view of Figure 3(a). The details of the cleaning device for a moving handrail according to the present invention will be described below with reference to these figures.
[0031] The cleaning device 30 for a moving handrail according to the present invention is fixed to the escalator so as to contact the moving handrail in the order of the cleaning means 6, the coating means 2, and the wiping means 3 from the upstream side with respect to the moving direction of the moving handrail indicated by the arrow in Figure 3(a). The fixing position to the escalator is preferably fixed so as to be located below the center of the semi-circle at the side end of the escalator. In addition, in Figures 3(a) and (b), the cleaning device 30 is illustrated with the fixing means omitted.
[0032] The cleaning means 6 is in a state of falling downstream by contacting the handrail. Further, the wiping means 3 is in contact with the surface of the moving handrail, and the tip portions of the adjacent pad members 3b, 3b are continuously overlapped, and the central portions of the adjacent pad members 3b, 3b have a gap 3d. Thereby, the strength of the pad member 3b can be strengthened, it can be strongly contacted with the moving handrail, and uneven wiping of the liquid can be prevented. In addition, since the side surface of the pad member 3b can be pressed against the surface of the moving handrail, the contact area increases, and uneven wiping of the liquid can be further prevented. Further, since the central portions of the adjacent pad members 3b, 3b have a gap 3d, the volatilization effect of the liquid absorbed by the pad member 3b can be enhanced, and the liquid absorption performance of the tip portion of the pad member can be maintained even after long-term use.
[0033] In addition, the gap 3d in the central portion functions so that the pad member 3b can be bent, and the impact force from the moving handrail with undulation can be released by the bending of the pad member 3b, and the influence of the impact force on the entire cleaning device can be alleviated.
[0034] In addition, the wiping means 3 is installed such that the contact surface of the pad member 3b with the handrail for movement contacts the surface of the handrail for movement obliquely from below. As a result, the pad member 3b can move the liquid in the direction of the base using gravity, so that the liquid absorption performance can be improved.
[0035] Figs. 4(a) to 4(d) are perspective views showing other embodiments of the wiping means. In the wiping means 11 shown in Fig. 4(a), the base portions of adjacent pad members 11b, 11b are integrally welded and fixed to form a welded portion 15. As a result, a base made of metal or resin is not required, so that the manufacturing cost can be reduced and the trouble of disassembling at the time of disposal can be eliminated.
[0036] In the wiping means 12 shown in Fig. 4(b), a desiccant 16 is disposed in the gap at the center of adjacent pad members 12b, 12b. As a result, the desiccant 16 absorbs the moisture of the liquid contained in the pad member 12b, so that the volatilization effect of the pad member 12b can be enhanced.
[0037] The wiping means 13 shown in Fig. 4(c) has a wiper member 17 having a draining function at the tip of some of the pad members 13b, and the wiper member 17 is formed on the downstream side of the movement of the handrail for movement. As a result, the effect of removing the liquid adhering to the handrail for movement can be enhanced. In addition, a microfiber 18 is attached to the tip of the pad member 13b located on the most downstream side of the movement of the handrail for movement. As a result, the moisture dammed up by the wiper member 17 can be attached to and removed by the microfiber 18, and the moisture that could not be completely removed by the pad member 13b or the wiper member 17 can be removed by the highly absorbent microfiber 18, so that no liquid remains on the handrail for movement. Incidentally, by making the wiper member 17 and the microfiber 18 concave so as to correspond to the shape of the handrail for movement, the contact area with the handrail for movement can be increased and the removal performance can be improved.
[0038] The wiping means 14 shown in Fig. 4(d) connects and fixes the base portions of the respective pad members 14b with a substantially plate-shaped substrate 14a, and a drain hole 14c is formed at substantially the center of the substrate 14a. Thereby, it is possible to suppress the accumulation of liquid at the base portions of the pad members 14b, and the volatilization effect of the pad members 14b can be maintained.
