[0005] [Patent Document 1] Jpn. Jpn. Published No. 48-37995 [Patent Document 2] Japanese Utility Model Application Publication No. 61-25375 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the external shape of the safety belt will undergo some deformation with use, and if the positioning is not performed accurately during installation, the safety belt may come into contact with the fixed part or handrail cover, etc., as it passes through the disinfection and wiping device of Patent Document 1 or the handrail cleaning tool of Patent Document 2, causing it to become misaligned, and the safety belt may not be properly cleaned.

[0007] The present invention is devised to solve the above-mentioned problems of the conventional art, and aims to provide a moving handrail cleaning device that can accurately position the gap distance between the moving handrail and the frame of the fixing means that constitutes the moving handrail cleaning device. [Means for solving the problem]

[0008] In order to solve the above-mentioned problems, the invention of claim 1 is a cleaning device for a moving handrail, comprising: a fixing means fixed to a guide rail that guides a moving handrail; and a cleaning device main body that cleans, washes or sterilizes the moving handrail, wherein the fixing means comprises a frame body composed of a plurality of long frame pieces arranged approximately in parallel and a plurality of short frame pieces arranged with their longitudinal direction approximately perpendicular to the long frame pieces, a pressing member installed on two of the plurality of long frame pieces, and a positioning mechanism installed on at least one of the plurality of short frame pieces, wherein each of the pressing members has an abutment portion that abuts against a side surface of the guide rail and a biasing means that biases the contact portion, and wherein the positioning mechanism abuts against the surface of the moving handrail with the fixing means temporarily fixed to the guide rail and determines the distance of the gap between the moving handrail and the frame body, and is characterized in that the fixing means has a cushioning means at the point of contact with the moving handrail to absorb impact from the moving handrail.

[0009] The invention of claim 1 allows accurate positioning by the cushioning means constituting the positioning mechanism coming into contact with the surface of the moving handrail during installation. Also, after installation, when the moving handrail is undulating, the cushioning means comes into contact with the moving handrail to reduce the impact from the moving handrail.

[0010] The invention of claim 2 is characterized in that in the invention of claim 1, the buffer means is provided with a roller that can rotate in the moving direction of the moving handrail. In this way, the roller not only contacts the moving handrail but also rotates in the moving direction of the moving handrail, thereby further mitigating the impact.

[0011] The invention of claim 3 is characterized in that in the invention of claim 2, the rollers are formed to abut at positions equidistant on both the left and right from the approximate center of the short side of the moving handrail. This allows for more accurate positioning and enhances the effect of the buffer means in absorbing impacts from the moving handrail.

[0012] The invention of claim 4 is characterized in that in any one of the inventions of claims 1 to 3, the buffer means includes a soft member having a hardness lower than that of the moving handrail. This makes it possible to prevent the buffer means from damaging the moving handrail.

[0013] The invention of claim 5 is characterized in that in any of the inventions of claims 1 to 4, the positioning mechanism is installed on two of the multiple short frame pieces. This allows for more accurate positioning and enhances the effect of the buffering means in absorbing impacts from the moving handrail.

[0014] The invention of claim 6 is characterized in that in any one of the inventions of claims 1 to 5, the positioning mechanism has a protruding mechanism that moves the buffer means so that it can appear and disappear, and the buffer means is movable between an initial position where it abuts against the surface of the moving handrail and a use position where it cushions the impact from the moving handrail between the moving handrail and the cleaning device main body with the fixing means fixed to the guide rail. As a result, the buffer means is not always in contact with the moving handrail, so that wear of the buffer means can be prevented, and the cleaning device main body can be prevented from receiving an impact from the moving handrail even in the use position.

[0015] The invention of claim 7 is characterized in that in the invention of claim 6, the cleaning device body is detachably fixed to the fixing means, and when the cleaning device body is fixed to the fixing means, the buffer means is movable from the initial position to the use position. This allows the buffer means to be reliably moved to the use position. 0 Effect of the Invention

[0016] The invention of claim 1 can perform accurate positioning and can absorb shock from the moving handrail. The invention of claim 2 can further absorb shock. The invention of claim 3 can perform even more accurate positioning. The invention of claim 4 can prevent damage to the moving handrail by using a buffer means.

[0017] The invention of claim 5 allows for more accurate positioning and enhances the effect of the shock absorber in absorbing shock from the moving handrail. The invention of claim 6 prevents wear on the shock absorber. The invention of claim 7 allows for reliable movement of the shock absorber to the usage position. [Brief description of the drawings]

[0019] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Note that the present invention is not limited to this embodiment. Fig. 1 is a perspective view of a cleaning device for a moving handrail according to the present invention, and Fig. 2(a) is an exploded perspective view showing 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 with reference to these drawings.

[0020] As shown in Fig. 1, the cleaning device 30 for the moving handrail has a fixing means 20 fixed to a guide rail that guides the moving handrail, and a cleaning device main body 10 that cleans, washes or sterilizes the moving handrail. The fixing means 20 is formed with a front suppression member 20a to prevent children from accidentally inserting their hands into the front opening through which the moving handrail passes, and a rear suppression member 20b is similarly formed at the rear opening. The cleaning device main body 10 is attached to the fixing means 20 in a detachable manner.

[0021] The cleaning device main body 10 has a housing 1 and a cleaning unit 5 arranged inside the housing 1, and the housing 1 has a housing main body 7 having an opening 7a and a lid 8 for opening and closing the opening 7a. The cleaning unit 5 also has, on a plate 5a, application means 2 that contacts the surface of the moving handrail to apply liquid, wiping means 3 that contacts the surface of the moving handrail to wipe off the liquid, liquid supply means 4 that supplies liquid to the application means 2, and cleaning means 6 that contacts the surface of the moving handrail to remove dirt.

[0022] The cleaning unit 5 is detachably attached to the housing 1. Specifically, a plate 5a constituting the cleaning unit 5 is detachably attached to a cover 8 constituting the housing 1.

[0023] The cover 8 is formed in a substantially flat plate or cup shape, and one end of the cover 8 is rotatably connected to the housing body 7 via a hinge 7b. A protective member 8a is formed on the outer surface of the cover 8. If the protective member 8a is formed at a position where the cover 8 hits the floor surface when the cover 8 is opened, the cover 8 can be prevented from being damaged. The protective member 8a can also protect the built-in cleaning unit 5 by absorbing the impact when a user of the escalator accidentally kicks the cover 8 or when a suitcase hits the cover 8.

[0024] The shape of the lid body 8 may be substantially flat instead of substantially cup-shaped, and the plate 5a constituting the cleaning unit 5 may be detachably attached to the housing body 7 constituting the housing 1, which is also included in the present invention. The case in which the lid body 8 is opened and closed by sliding relative to the housing body 7 is also included in the present invention.

[0025] Fig. 2(b) is an exploded perspective view showing the fixing means constituting the cleaning device for a moving handrail according to the present invention. The details of the fixing means will be described with reference to this figure. The fixing means 20 has a frame body 21 that is approximately square-shaped in plan view and pressing members 22, 22 installed on one of the two opposing sides of the frame body 21. Each of the pressing members 22, 22 is provided along the longitudinal direction of the frame body 21 and has a contact portion 22a that contacts the side surface of the guide rail and a plurality of pressing means 22b, 22b... that press the contact portion 22a. This allows the guide rail to be firmly fixed without processing it. The pressing means 23b is composed of a strong compression coil spring.

[0026] The square-shaped frame body 21 is composed of two long frame pieces 21a, 21a formed of a plate-like member and two short frame pieces 21b, 21b formed of a plate-like member and arranged with their longitudinal direction substantially perpendicular to the long frame pieces 21a, 21a. Protrusions 27, 27 for temporary fixing are formed at both ends of the short frame piece 21b, and fixing holes 35, 35 are formed near the protrusions 27. A temporary fixing hole 28 is formed at the position of the long frame piece 21a facing the protrusions 27, and fixing holes 29, 29 are formed near the temporary fixing hole 28. Then, with the protrusions 27 inserted into the temporary fixing holes 28, screw members 33 are screwed into each other's fixing holes 29, 35 to form the square-shaped frame body 21.

[0027] The frame body 21 has a reinforcing portion A23 formed along the short side of the two long frame pieces 21a, 21a, which are two opposing sides, and a reinforcing portion B24 formed along the longitudinal direction of the two short frame pieces 21b, 21b, which are the other opposing two sides. In addition, the frame body 21 has a reinforcing portion C25 formed along the longitudinal direction of the two long frame pieces 21a, 21a, which are one of the opposing two sides. The longitudinal direction of the reinforcing portion C25 is parallel to the longitudinal direction of the pressing member 22. Since the frame body 21 has the reinforcing portion A23, the reinforcing portion B24, and the reinforcing portion C25, it is possible to prevent the frame body from being deformed by an external force or the force of the biasing means, and it is possible to provide a compact cleaning device for a moving handrail that does not become large. In addition, a positioning mechanism 34 is attached to the two short frame pieces 21b, 21b by a screw member 36.

[0028] The frame body 21 is formed of a long frame piece 21a and a short frame piece 21b, which are plate-like members, and the reinforcing portion A23 is formed by bending both longitudinal ends of the long frame piece 21a into a substantially L-shape. The reinforcing portion B24 is formed by bending one lateral end of the short frame piece 21b into a substantially L-shape. This makes it possible to ensure a predetermined strength without adding and installing a new reinforcing member to the frame body 21, thereby reducing manufacturing costs.

[0029] The surface of the pressing member 22 that comes into contact with the guide rail is formed of a soft member 37. Examples of the soft member 37 include double-sided tape and rubber members. This allows the fixing means to be firmly fixed without damaging the guide rail. In addition, the frictional force with the guide rail increases, preventing the fixing means from shifting.

[0030] The pressing member 22 has a restricting means 26 that connects the contact portion 22a to the frame body 21 and can fix the contact portion 22a close to the frame body 21 while receiving the biasing force of the biasing means 22b. This allows the installation work to be performed in a state where the biasing force of the biasing means 22b is restricted by the restricting means 26, making it easy to attach the pressing member 22 to the guide rail. The restricting means 26 is preferably located approximately in the center of the pressing member 22 in the longitudinal direction, and it is sufficient to provide at least one restricting means 26, but it is also possible to provide multiple restricting means 26 along the longitudinal direction of the pressing member 22. The restricting means 26 can be formed of a bolt that is screwed into the pressing member 22.

[0031] When fixing the fixing means 20 to the guide rail, it is attached in a state where the biasing force of the biasing means 22b is restricted by the restricting means 26, and after attachment, the restriction of the restricting means 26 is released, and the abutting parts 22a firmly hold the guide rail from both sides by the biasing force of the biasing means 22b. If the restricting means 26 is configured with a bolt, the bolt may be removed after attachment, which can reduce weight and prevent the bolt from being lost.

[0032] The longitudinal direction of the reinforcing portion A23 and the longitudinal direction of the reinforcing portion C25 are formed so as to be perpendicular to each other, thereby effectively reinforcing the urging force of the urging means 22b applied to the frame body 21, and preventing the frame body 21 from being deformed.

[0033] FIG. 3(a) is a perspective view showing a state in which the cleaning device for a moving handrail according to the present invention is fixed to an escalator, and FIG. 3(b) is a perspective view showing a state in which the fixing means constituting the cleaning device for a moving handrail according to the present invention is fixed to an escalator. The cleaning means, the coating means, and the wiping means are fixed to the escalator so as to abut against the moving handrail 31 in this order from the upstream side with respect to the moving direction of the moving handrail 31 indicated by the arrow. The fixing position to the escalator is preferably fixed to be located lower than the center of the semicircle at the side end of the escalator. In addition, the cleaning device 30 is formed with a front suppression member 20a and a rear suppression member 20b at the front opening and rear opening through which the moving handrail passes, to prevent children from accidentally inserting their hands.

[0034] Since the cleaning device body 10 is detachably attached to the fixing means 20, the installation work on the escalator can be performed easily by first attaching only the fixing means 20 to the guide rail 32 and then attaching the cleaning device body 10 to the fixing means 20, which makes the installation work easy and simple.

[0035] FIG. 4(a) is a perspective view showing a positioning mechanism constituting the cleaning device for a moving handrail according to the present invention, and FIG. 4(b) is an exploded perspective view showing the same positioning mechanism. FIG. 5(a) is a cross-sectional view showing the initial position of the positioning mechanism constituting the cleaning device for a moving handrail according to the present invention, and FIG. 5(b) is a cross-sectional view showing the use position of the positioning mechanism. The details of the positioning mechanism will be described below using these figures. As shown in FIG. 4 and FIG. 5, the positioning mechanism 34 is fixed to the short frame piece 21b constituting the frame body 21, the reinforcing part B24 abuts on the upper part, and both sides are covered by the bent pieces 44, 44. Therefore, the structure is such that the impact force that the positioning mechanism 34 receives from the moving handrail is received by the short frame piece 21b.

[0036] The positioning mechanism 34 comes into contact with the surface of the moving handrail with the fixing means 20 temporarily fixed to the guide rail, and determines the distance of the gap between the moving handrail and the frame body 21, and has a buffer means 39 at the point of contact with the moving handrail to absorb impacts from the moving handrail. As a result, during installation work, accurate positioning can be achieved by the buffer means 39 constituting the positioning mechanism 34 coming into contact with the surface of the moving handrail. Also, after installation, if the moving handrail is wavy, the buffer means 39 comes into contact with the moving handrail to absorb impacts from the moving handrail.

[0037] The buffer means 39 is provided with two rollers 41, 41 rotatably supported in the moving direction of the moving handrail by pivot shafts 43, 43. These two rollers 41, 41 are formed to abut at positions equidistant on the left and right from approximately the center of the moving handrail in the short side direction. This allows for more accurate positioning. The number of rollers is not limited to two, and three or more rollers are also included in the present invention. The buffer means 39 is also provided with a spring 39a that biases upward in FIG. 5.

[0038] The buffer means 39 is provided with a soft member having a lower hardness than the moving handrail. Specifically, the rollers 41, 41 themselves may be made of a soft member, or a soft member may be attached to the contact surface of the rollers 41, 41 with the moving handrail. Alternatively, instead of the rollers, for example, a convex soft member protruding toward the moving handrail may be formed, and the present invention includes any structure that has a positioning function and does not scratch the moving handrail when it contacts it. The rollers 41, 41 according to the present invention have a soft member formed on the contact surface with the moving handrail, but even if no soft member is formed, the rollers slide and can absorb the impact from the moving handrail.

[0039] The positioning mechanism 34 has a protruding mechanism 38 that moves the buffer means 39 so that it can appear and disappear, and the protruding mechanism 38 is equipped with springs 38a, 38a that urge the protruding mechanism leftward in Fig. 5. The buffer means 39 and the protruding mechanism 38 are attached to the short frame piece 21b with screws 42, 42, with a portion of them enclosed within the cover 40.

[0040] With the fixing means fixed to the guide rail, the buffer means 39 is movable between an initial position (Figure 5(a)) in which it abuts against the surface of the moving handrail, and a usage position (Figure 5(b)) in which it cushions the impact from the moving handrail between the moving handrail and the cleaning device main body.

[0041] Specifically, when the button 38b shown in Fig. 5(a) protrudes forward from the cover 40, the abutment surface 38c of the protruding mechanism 38 abuts against the abutment surface 39c of the buffer means 39, the spring 38a is in an expanded state, and the spring 39a is in a contracted state. Also, the levers 39b, 39b of the buffer means 39 are lowered downward within the cover 40, and the lower portions protrude from the cover 40. In this state, the roller 41 abuts against the surface of the handrail 31 to be positioned, and the fixing means is fixed to the guide rail.

[0042] On the other hand, when the button 38b shown in Fig. 5(b) does not protrude forward from the cover 40, the contact surface 38c of the protruding mechanism 38 is displaced backward from the contact surface 39c of the buffer means 39, and the spring 38a is contracted and the spring 39a is extended. Also, the levers 39b, 39b of the buffer means 39 are raised upward within the cover 40, and the lower part is stored in the cover 40. In this state, the roller 41 maintains a certain distance from the surface of the handrail 31.

[0043] The cleaning device body is detachably fixed to the fixing means, and when the cleaning device body is fixed to the fixing means, the buffer means 39 is movable from the initial position to the use position. Specifically, when the cleaning device body is fixed to the fixing member in the state shown in FIG. 5(a), the contact portion 1a of the housing constituting the cleaning device body pushes the button 38b toward the inside of the cover 40, and the state of the use position shown in FIG. 5(b) can be achieved. In this use position state, the roller 41 is closer to the surface of the moving handrail than the short frame piece 21b, and when the moving handrail is wavy, it is designed to abut against the roller first. In addition, the positioning mechanism 34 is installed on each of the other two opposing sides (short frame pieces 21b, 21b) of the frame body, so that the roller 41 comes into contact with four points of the moving handrail, and both the distance of the gap between the frame body constituting the fixing means and the moving handrail and the inclination of the fixing means can be accurately positioned. In addition, the effect of mitigating the impact from the moving handrail by the buffer means 39 can be enhanced.

[0044] Furthermore, if the buffer means 39 is not configured to be movable from the initial position to the usage position, the roller 41 will be in constant contact with the moving handrail, but since the roller rotates, it is possible to reduce the impact from the moving handrail.

[0045] Furthermore, the shape of the frame body is not limited to a square shape formed by a long frame piece and a short frame piece with its longitudinal direction set approximately perpendicular to the long frame piece, but may be, for example, a square shape formed by two long frame pieces and three short frame pieces, a check shape formed by two long frame pieces and four short frame pieces, or a square shape formed by three long frame pieces and three short frame pieces. When a square, check, or check-shaped frame body is formed, the gap distance between the fixing means and the moving handrail and the inclination of the fixing means can be more accurately positioned by arranging a short frame piece with a positioning mechanism approximately in the center of the longitudinal direction of the frame body.
