Description

  The present invention relates to a step cleaner for cleaning a step of an escalator.

  An escalator is a device used for the movement of people between the floors of a building. The escalator has a plurality of steps that move and balustrades on both sides of the steps, and is mounted from the lower floor to the upper floor. Both balustrades have balustrade inner plates on opposite surfaces. The step includes a tread plate that can be stepped on by a passenger and a riser (step riser) that corresponds to the raising of a staircase (see Non-Patent Document 1). The tread has a cleat groove and is also called a step cleat. The escalator has, at the entrance / exit, a comb (comb) that meshes with the cleat groove and a comb plate that supports the comb.

  If an escalator is used, the steps will be soiled and must be cleaned. Cleaning the risers of the steps is important to prevent the transfer of dirt to the hem of passenger clothing, baggage and the like. The main purpose of cleaning the treads of the steps is to improve aesthetics. 2. Description of the Related Art Conventionally, in order to save labor for cleaning a step, a cleaning machine is known in which a cleaning brush is slidably contacted with a step using the movement of the step.

  As such a device, there is known a cleaning device that cleans a riser (riser surface) by using a downward movement of a step (see, for example, Patent Document 1 and Patent Document 2). However, such a cleaning device does not clean the footboard.

  Further, there is known a cleaning device that uses a movement of a step to clean a step board (step) with a brush (cleaning brush body material) (see, for example, Patent Document 3). However, such a cleaning device does not clean the riser.

  There has been proposed a man conveyor step cleaning machine that cleans both a riser (riser surface) and a tread plate (step surface) with a brush (cleaning tool) by using the downward movement of the step (see Patent Document 4). However, in this man conveyor step cleaner, the angle between the surface of the riser on the side away from the brush and the bristles becomes an obtuse angle (see Fig. 4 of the same document), and the bristles come in contact with the riser so that the riser rises. It is not easy to remove dirt adhering to the surface. Also, the angle between the surface of the tread plate on the side away from the brush and the bristles becomes a small acute angle (see Fig. 5 of the same document), and the brush contacts the tread plate so that frictional vibration of the brush easily occurs. The sliding contact with the tread is unstable, and the tread is not easy to clean.

  In addition, as a cleaner that cleans both the riser (step riser) and the tread plate (step tread surface) with a brush using the descending movement of the step, a conveyor step cleaner has been proposed in which the brush can be displaced in the horizontal direction. (See Patent Document 5). However, in Embodiment 1 of the conveyor step cleaning machine, since the brush can be displaced only in the horizontal direction, it is not easy to clean the stepping plate that moves downward (see paragraph 0037 of the specification). Further, in Embodiment 2 of the conveyor step cleaning machine, the brush is freely displaceable in the horizontal direction and the vertical direction (2 degrees of freedom) (see FIG. 7 of the same document). Hard astringency is likely to occur and the reliability is not high.

A stepping plate brush for sliding, and as the step moves downward, the riser brush is in sliding contact with the riser and the stepping plate brush is in sliding contact with the stepping plate. And

  In this step cleaner, it is preferable that the riser brush has substantially horizontal bristles, and the tread plate brush has substantially vertical bristles.

  In this step cleaner, it is preferable that the fixed portion is attached to a balustrade inner plate of an escalator and supports the movable arm in a swingable manner.

  In this step cleaning machine, the fixed portion has a rotation shaft parallel to the width direction of the escalator, the movable arm swings around the rotation shaft, and the rotation shaft is separated in the radial direction. Preferably, the movable arm has a weight at a position, and the movable arm presses the cleaning brush body against the step by a moment generated by the weight on the rotation shaft.

  In this step cleaner, the fixed portion may be placed on an entrance / exit of an escalator and may support the movable arm so as to be linearly movable in an oblique direction toward the riser and the tread plate.

  In this step cleaner, the fixed portion may be attached to a comb plate at an entrance / exit of the escalator, and may support the movable arm so as to be linearly movable in an oblique direction toward the riser and the step plate.

  According to the step cleaner of the present invention, since it has the riser brush and the treadle brush, the riser brush is suitable for cleaning the riser, and the treadle brush is suitable for cleaning the tread plate. The riser and the footboard can be cleaned more easily than cleaning both with the same brush.

The movable arm 4 is capable of relative movement with one degree of freedom with respect to the fixed portion 3.

  FIG. 2 shows the step cleaning machine 1 provided on the escalator 5 by cutting the configuration of the right side in the downward direction of the escalator 5 (the direction indicated by the white arrow). In addition, the step cleaning machine 1 is substantially bilaterally symmetric, and the configuration of the left side portion in the downward direction of the escalator 5 is the same. The cleaning brush body 2 includes a riser brush 21a and a tread plate brush 21b. The riser brush 21 a is a brush for cleaning the riser 51 a of the step 51 in the escalator 5. The tread board brush 21 b is a brush for cleaning the tread board 51 b of the step 51.

  The riser brush 21a has substantially horizontal brush hairs. The treadle brush 21b has substantially vertical brush hairs.

  The fixing portion 3 is attached to the balustrade inner plate 52 of the escalator 5. The fixed portion 3 supports the movable arm 4 so as to be swingable.

  The fixed part 3 has a rotation shaft 31 parallel to the width direction of the escalator 5. The movable arm 4 swings around the rotation shaft 31. The rotating shaft 31 has a weight 6 at a position separated in the radial direction. The weight 6 generates a moment (a moment of force) on the rotating shaft 31. The movable arm 4 presses the cleaning brush body 2 against the step 51 by a moment generated by the weight 6 on the rotation shaft 31.

  Each configuration of the step cleaner 1 will be described in further detail. Generally, a brush has many brush hairs and a planting solid, and the root of the brush hair is held by the planting solid. The riser brush 21a of the cleaning brush body 2 is designed such that the direction, length, hardness, density, material, and the like of the bristle are suitable for cleaning the riser 51a. The treadle brush 21b is designed such that the direction, length, hardness, density, material, and the like of the bristle are suitable for cleaning the tread 51b. The cleaning brush body 2 has an elongated planting solid 22 parallel to the width direction of the escalator 5. The length of the planting solid 22 is substantially the same as the width of the step 51 and is shorter by the clearance. In the present embodiment, the riser brush 21a and the tread board brush 21b share the planted solid 22. The riser brush 21a is a brush in which a large number of bristles are provided substantially horizontally on the planted solid 22, and the tip of the bristles abuts the riser 51a substantially vertically in a state of sliding in contact with the riser 51a. The treadle brush 21b is a brush in which a large number of bristles are provided substantially vertically on the planted solid 22, and the tip of the bristles abuts the tread plate 51b substantially vertically in a state of sliding in contact with the tread plate 51b. The bristles of the riser brush 21a and the tread board brush 21b may have the same length, hardness, density, material, and the like other than the direction. Further, the riser brush 21a and the tread board brush 21b may have different planting solids.

  In the present embodiment, the fixed portion 3 has suction cups 32 at both ends of the rotating shaft 31, and is detachably provided by the suction cups 32 on the immovable portion of the escalator 5. The suction cup 32 is attracted to the balustrade inner side plate 52 which is a stationary part of the escalator 5.

  The movable arm 4 is a long member, a base end portion is fixed to the rotating shaft 31, extends in the radial direction of the rotating shaft 31, and is swingable about the rotating shaft 31. Since the movable arm 4 swings, it is also called a movable lever body. The cleaning brush body 2 is displaced in an arc shape by the swing of the movable arm 4. According to the mechanics, the relative motion of the movable arm 4 with respect to the fixed portion 3 is a rotational motion and has one degree of freedom.

  The weight 6 is cantilevered on the rotary shaft 31 by a long support lever body 61. A long reinforcing member 62 is obliquely provided between the support lever body 61 and the movable arm. A moment is generated around the rotation shaft 31 due to the weight of the weight 6, and the support lever body 61 rotates the rotation shaft 31. Due to the rotation of the rotating shaft 31, the movable arm 4 swings in the direction in which the cleaning brush body 2 is pressed against the step 51.

  In the present embodiment, the step cleaner 1 includes a pair of suction cups 32, the movable arm 4, a support lever body 61, and a reinforcing material 62. The rotating shaft 31 is supported at both ends by a pair of suction cups 32. The cleaning brush body 2 is substantially supported at both ends by a pair of movable arms 4. Both ends of the weight 6 are substantially supported by a pair of support lever bodies 61.

  Cleaning of the step 51 using the step cleaner 1 will be described with reference to FIGS. 3 to 5. 3 to 5 show the state of the step cleaner 1 when the step 51 of the escalator 5 is moving downward, in chronological order. As shown in FIG. 3, first, as preparation for step cleaning, the escalator 5 is stopped, and the suction cup 32 of the step cleaning machine 1 is attached to the balustrade inner plate 52 that is a stationary part of the escalator 5. As an initial state of the step cleaner 1, the riser brush 21a of the cleaning brush body 2 comes into contact with the lower portion of the riser 51a of one step 51B, and the step plate brush 21b comes into contact with the step plate 51b of the lower step 51A. Next, the suction cup 32 is positioned.

  Next, the escalator 5 is activated and the step 51 moves downward in the direction of the white arrow. As shown in FIG. 4, as the step 51 moves downward, the riser brush 21a comes into sliding contact with the riser 51a of the step 51B, and the riser 51a of the step 51B is cleaned.

  When the cleaning brush body 2 crosses the top of the riser 51a of the step 51B as the step 51 moves downward, the stepping brush 21b and the stepping plate 51b of the step 51B are moved from the state in which the riser brush 21a is in sliding contact with the riser 51a. Switch to the sliding contact state. As shown in FIG. 5, the tread plate brush 21b comes into sliding contact with the tread plate 51b of the step 51B, and the tread plate 51b is cleaned.

  When the cleaning brush body 2 comes into contact with the bottom of the riser 51a of the step 51C as the step 51 moves downward, the riser brush 21a is brought into sliding contact with the step plate 51b of the step 51B. It switches to the state of sliding in contact with the riser 51a. Similarly, as the step 51 moves downward, the state where the riser brush 21a is in sliding contact with the riser 51a and the state where the stepping plate brush 21b is in sliding contact with the stepping plate 51b are switched. While the state of sliding contact with the step 51 of the cleaning brush body 2 is switched in this way, the riser 51a and the step board 51b are alternately cleaned.

  When the cleaning of all the steps 51 of the escalator 5 is completed, the escalator 5 is stopped, the suction cup 32 is removed from the balustrade inner plate 52, and the step cleaner 1 is removed from the escalator 5.

  As mentioned above, according to the step cleaner 1 which concerns on 1st Embodiment, since it has the brush 21a for a riser and the brush 21b for a step board, the brush 21a for a riser shall be suitable for the cleaning of the riser 51a, and the brush 21b for a step board Can be made suitable for cleaning the tread plate 51b (individual optimization), and the riser 51a and the tread plate 51b can be easily cleaned rather than cleaning both with the same brush. Further, the movable arm 4 to which the cleaning brush body 2 is attached can be moved relative to the fixed portion 3, that is, the non-moving portion of the escalator 5 with one degree of freedom. Is expensive.

  Since the bristles of the riser brush 21a are substantially horizontal, and the brush bristles for the footboard 21b are substantially vertical, the bristles of the riser brush 21a abut on the riser 51a substantially vertically, and the treadle brush 21b Thus, the riser 51a and the tread plate 51b can be cleaned more easily than when the brush bristles are in contact with the tread plate 51b substantially perpendicularly.

  Since the movable arm 4 is swingably supported, it is difficult for the movable arm 4 to be hard and reliable.

  Since the cleaning brush body 2 is pressed against the step 51 by the moment generated by the weight 6, the step 51 can be easily cleaned.
