JP7469798B2 - Shoe sole cleaning device - Google Patents

Description

The present invention relates to a shoe sole cleaning device, and more specifically, to a shoe sole cleaning device that cleans the soles of shoes by rotating a brush with a tuft of bristles attached to it and bringing it into contact with the soles.

For example, shoe sole cleaning devices are used to clean shoe soles in a variety of situations, such as food preparation and processing sites, agricultural and civil engineering sites, etc. One example is a shoe sole cleaning device developed by the applicant of the present application (Patent Document 1: Japanese Patent No. 6430175). This device rotates inclined, parallel brushes while spraying cleaning water on them, and the soles of shoes are brought into contact with the brushes to remove dirt.

Japanese Patent No. 6430175

As a result of intensive research by the inventors of the present application, it was found that in the shoe sole cleaning device exemplified in Patent Document 1, the bristle bundle in the center of the brush has a small movement amount, so the cleaning ability is low and dirt on the shoe sole tends to remain attached. This causes the problem that dirt tends to re-adhere to the shoe sole of the next user of the device. Furthermore, if dirt falls onto the base of the bristle bundle in the center (base plate part), it tends to remain there, resulting in the problem of unsanitary conditions. In particular, there was a problem of reduced cleaning power for shoe soles with complex shapes.

From another perspective, there was a problem that the user's posture was unstable when the sole of the shoe was brought into contact with the rotating brush. Furthermore, if the sole of the shoe pressed down on the bristles of the brush, the bristles would become deformed, which not only reduced the effectiveness of removing dirt, but also shortened the brush's lifespan.

Furthermore, when washing one foot at a time, there was a problem that the washing time was long. On the other hand, when washing both feet in order to shorten the washing time, both feet had to be placed on the brush, which caused the user's posture to become unstable.

The present invention was made to solve the above-mentioned complex problems, and aims to realize a shoe sole cleaning device that has a high cleaning power even for the increasingly complex shapes of shoe soles, prevents dirt from the soles from remaining on the bristles of the brush, prevents dirt from re-adhering to the next user, improves hygiene, and further stabilizes the user's posture and extends the service life of the brush.

The present invention solves the above problems by the solutions described below.

The disclosed shoe sole cleaning device comprises a brush having a tuft of bristles attached in a predetermined arrangement to a base plate that is driven to rotate inside a cleaning tank, and cleaning water is sprayed onto the tuft of bristles while the brush is rotating, thereby bringing the sole of the shoe into contact with the tuft of bristles to clean it.A requirement of the device is that the brush is configured to be rotatable on the base plate with its axis aligned, thereby being relatively stationary, and has a footrest on which the foot is placed so that the sole of the shoe comes into contact with it.

The present invention makes it possible to realize a shoe sole cleaning device that has a high cleaning power even for shoe soles with complex shapes. In addition, it is possible to prevent dirt from the shoe sole from remaining on the bristles of the brush, which prevents the dirt from re-adhering to the next user and improves hygiene. It also makes it possible to stabilize the user's posture when cleaning the shoe sole. It also makes it possible to extend the service life of the brush.

Below, an embodiment of the present invention will be described in detail with reference to the drawings. Figs. 1 and 2 are schematic diagrams showing an example of a shoe sole cleaning device 1 according to an embodiment of the present invention, with Fig. 1 being a perspective view seen from the upper left, and Fig. 2 being a perspective view seen from the upper right. For ease of explanation, arrows may be used in the drawings to indicate the up-down, left-right, and front-rear directions of the shoe sole cleaning device 1. In addition, in all the drawings used to explain the embodiment, components having the same functions are given the same reference numerals, and repeated explanations of such components may be omitted.

As mentioned above, the shoe sole cleaning device 1 is a device used to clean shoe soles, for example, at sites where food is prepared or processed, or where agricultural or civil engineering work is carried out. In summary, the device is configured to clean shoe soles by spraying cleaning water onto a brush bristle bundle while rotating and bringing the brush into contact with the soles. Each component will be described in detail below.

1 and 2, the shoe sole cleaning device 1 according to this embodiment is configured with a cleaning tank 12 in a main body 10, and a brush 20 that is rotated is provided inside the cleaning tank 12. Inside the main body 10, a drive source 14 (e.g., an electric motor) that rotates the brush 20 and a control unit 16 that controls the drive and the like are provided. The main body 10 is also provided with a sensor 18 (here, an infrared sensor) that detects that a shoe to be cleaned has been placed on the brush 20. As an operation, a detection signal by the sensor 18 that a shoe has been placed is transmitted to the control unit 16. This is used as a trigger to start cleaning, and a drive signal is transmitted from the control unit 16, and the drive source 14 is driven to rotate the brush 20 for a preset time (e.g., about 15 seconds), and cleaning water is delivered from a delivery tube 22 (described later). Note that instead of automatic start by the sensor 18, a start switch may be provided in the main body 10 so that the user can operate the start and the time (not shown).

Water (tap water) is supplied into the device from the water supply unit 42 as the cleaning water. At this time, liquid detergent is sucked into the device from the detergent supply unit 44 and mixed with the water (tap water) due to the ejector effect caused by the flow of water (however, cleaning may be performed using water only). Alternatively, electrolytic water (electrolytic hypochlorous water, etc.) can be used as the cleaning water instead of water (tap water). This can enhance the sterilization effect. Meanwhile, wastewater generated during cleaning is discharged from the drainage unit 46 to the outside of the device.

Next, schematic diagrams of the cleaning tank 12 are shown in Figures 3 to 5, and schematic diagrams of the brush 20 are shown in Figures 6 to 9. More specifically, Figure 3 is a plan view of the cleaning tank 12, Figure 4 is a plan view of the cleaning tank 12 with the splash prevention cover 24 (described later) removed, and Figure 5 is a cross-sectional view taken along line V-V in Figure 3. Also, Figure 6 is a perspective view of the brush 20, Figure 7 is a front view of the brush 20, Figure 8 is a plan view of the brush 20, and Figure 9 is a cross-sectional view taken along line IX-IX in Figure 8.

The cleaning tank 12 according to this embodiment is formed in a box shape with a bottom (i.e., a rectangular parallelepiped shape with an open top) using a metal material (e.g., stainless steel alloy, etc.). As an example, on the left side of the cleaning tank 12, two brushes 20 are arranged side by side in the front-to-rear direction (left brush 20L1, left brush 20L2), and on the right side of the cleaning tank 12, two brushes 20 are arranged side by side in the front-to-rear direction (right brush 20R1, right brush 20R2).

Here, the brushes 20 (left brush 20L1, left brush 20L2, right brush 20R1, right brush 20R2) are configured as follows. Specifically, a foot rest 32 (described below) is provided on the top surface 30a of a disk-shaped base plate 30, with the axis C coinciding with the radial center position, and bristle bundles 34 are attached in a predetermined arrangement in the area excluding the area where the foot rest 32 is located.

This base plate 30 is rotated by the drive source 14 via a drive mechanism (not shown) consisting of a pulley, chain, etc. This causes the bristle bundle 34 on the base plate 30 to rotate, and the shoe sole can be cleaned, i.e., dirt removed, by contacting the upper part of the bristle bundle 34. In this embodiment, the base plate 30 is arranged to rotate in a horizontal plane.

In addition, the cleaning tank 12 is provided with a delivery pipe 22 that delivers cleaning water to the brush 20 (here, the bristle bundle 34). Specifically, the delivery pipe 22 is arranged at the side of each brush 20 (left brush 20L1, left brush 20L2, right brush 20R1, right brush 20R2) with the water outlet 22a facing the center of the base plate 30. By appropriately controlling the amount of cleaning water delivered by the control unit 16, the cleaning water (shown by the dashed line in FIG. 5) can be applied to a predetermined position of the bristle bundle 34 (for example, a position about halfway between the center and the outer periphery of the base plate 30). This allows cleaning water to be supplied from above to the tip (upper end) of the bristle bundle 34. Therefore, the bristle bundle 34 (tip) can be brought into contact with the sole while retaining a large amount of cleaning water at the tip, thereby further improving the cleaning effect. In addition, cleaning can be performed with running water (overflowing) rather than by immersing in stored water, which improves hygiene. Each brush 20 is configured so that the height of the tip position of the bristle bundles 34 is the same, but this is not limited to this and the heights may be different (not shown).

Here, the base plate 30 according to this embodiment is made of a resin material (e.g., polyvinyl chloride resin, etc.), has an outer diameter of about 150 mm, and has an upper surface 30a that is inclined downward at a predetermined angle (e.g., about 3°) from the center (axis C) toward the outside in the radial direction (inclined surface). This, combined with the configuration in which the footrest 32 is provided in the center of the base plate 30 and the bristles 34 are not attached, has the effect that dirt removed by contacting the bristles 34 with the sole of the shoe flows down the inclined surface together with the washing water by the action of centrifugal force and gravity and is discharged outside the base plate 30, and does not remain in the center of the base plate 30. This solves the problem of dirt re-adhering to the next user, and improves hygiene.

On the other hand, the bristle bundle 34 is made of a resin material (e.g., polypropylene resin, etc.) and is made by bundling a plurality of bristles (linear bodies) with a total length of about 40 mm (e.g., about 10 to 20 bristles) into a unit bundle, and the unit bundles are arranged in a row on the base plate 30 from the center toward the outside in the radial direction, except for the area where the foot rest 32 is arranged. As an example, it is preferable that the rows are arranged in 5 to 8 rows (6 rows in this embodiment) in the circumferential direction. The inventor's research has revealed that when the bristle bundles are arranged densely as in the configuration of the conventional device (Patent Document 1), the bristle bundles are not bent and the shoe sole is placed on the bristle bundles, making it difficult for the bristle bundles to enter the grooves of the shoe sole, resulting in a reduced cleaning effect. In order to solve this problem, a comparative example was examined in which the bristles constituting the bristle bundles were changed to softer bristles, and it was found that while the bristle bundles are easier to enter the grooves of the shoe sole, their power to remove stubborn dirt is reduced, resulting in a reduced cleaning effect.

In contrast, according to the configuration of the present embodiment, the spacing between the bristle bundles 34 (here, the row of bristle bundles 34) is set wider than in the past, creating space for the bristle bundles 34 to bend, which enhances the cleaning effect. In addition, the density of the bristle bundles 34 is reduced, which makes it easier for the bristle bundles 34 to enter the grooves of the sole, thereby enhancing the cleaning effect even for soles with complex shapes. Furthermore, even if dirt adheres to the bristle bundles 34, it is blown away by the momentum of the bristle bundles 34 as they return to their original shape, so that the effect is that the dirt does not remain on the bristle bundles 34. This solves the problem of dirt re-adhering to the next user, and improves hygiene.

Here, the footrest 32 provided on the base plate 30 has a configuration in which the upper member 32A and the lower member 32B are connected via a bearing 32C (for example, a thrust bearing made of a resin material). That is, this bearing 32C allows the footrest 32 to rotate with respect to the base plate 30. As an example, the upper member 32A is formed of a resin material (for example, polyvinyl chloride resin, etc.) into a hemispherical shape with a flat portion at the top end and a cylindrical space inside, with an outer diameter of about 50 mm. The lower member 32B is formed of a metal material (for example, stainless steel alloy, etc.) into a shape in which a small diameter cylindrical portion is erected from the center of a large diameter cylindrical portion. The bearing 32C is configured to be sandwiched between the lower surface of the upper member 32A and the upper surface of the lower member 32B. A bush 32D made of a resin material is disposed between the inner wall of the space portion of the upper member 32A and the outer wall of the small diameter cylindrical portion of the lower member 32B, and is configured to perform positioning and sliding action.

According to the above configuration, the footrest 32 (here, the upper member 32A) is configured to be rotatable on the base plate 30 with the axis C aligned. Therefore, when the base plate 30 is rotated, the footrest 32 (here, the upper member 32A) can be made stationary relative to the rotating base plate 30 by abutting the sole of the shoe against the upper member 32A of the footrest 32. In other words, the footrest 32 (here, the upper member 32A) can be made stationary while the base plate 30 is rotating, allowing the user to place their foot on it.

Here, the bearing 32C and the bearing 36 (e.g., a radial bearing made of a metal material) that rotatably supports the entire brush 20 under the load applied thereto are both configured to be able to support the assumed weight of the user in a distributed manner (here, distributed support at a total of four points, the left brushes 20L1, 20L2 and the right brushes 20R1, 20R2). Furthermore, as described above, the base plate 30 is configured to rotate within a horizontal plane. The main body 10 is provided with a handrail 50 that the user can grasp to stabilize the body. In this embodiment, by providing the handrail 50 on the right side (or the left side) of the cleaning tank 12, multiple shoe sole cleaning devices 1 can be connected in the front-rear direction, and the user can move in the front-rear direction above the cleaning tank 12 in the connected state (details will be described later).

With these configurations, the user can place their feet with the soles of their shoes in contact with the foot rest 32 while wearing their shoes, i.e., while standing on the foot rest 32, and the bristles 34 of the rotating brush 20 can come into contact with the soles of the shoes to perform cleaning. Therefore, both the left and right soles can be cleaned simultaneously, which shortens the time required for cleaning. In addition, the configuration in which the foot rest 32 supports the user's weight also eliminates problems such as deformation of the bristles of the brush caused by the soles of the shoes stepping on them, which has been the case in the past, and a shortened service life.

In this embodiment, the two left brushes 20L1 and 20L2 are configured to rotate in the same direction, and the two right brushes 20R1 and 20R2 are configured to rotate in the same direction, and the left brushes 20L1 and 20L2 and the right brushes 20R1 and 20R2 are configured to rotate in opposite directions. Specifically, the left brushes 20L1 and 20L2 rotate clockwise, and the right brushes 20R1 and 20R2 rotate counterclockwise (as indicated by the arrow R in FIG. 4). Alternatively, the left brushes 20L1 and 20L2 may rotate counterclockwise, and the right brushes 20R1 and 20R2 may rotate clockwise (not shown). According to this, when a user is standing on the footrest 32 with shoes on and cleaning the soles of his/her shoes, the force that the shoes (sole) receive by contacting the rotating brush 20 can be balanced, so that the user can stand on both feet without wobbling. In other words, both feet can be washed simultaneously and reliably, shortening the washing time.

Furthermore, the cleaning tank 12 is provided with at least three splash guard covers 24. Specifically, a splash guard cover 24A is provided on the left side of the left brushes 20L1, 20L2, a splash guard cover 24B is provided between the left brushes 20L1, 20L2 and the right brushes 20R1, 20R2, and a splash guard cover 24C is provided on the right side of the right brushes 20R1, 20R2. As an example, each splash guard cover 24 (24A, 24B, 24C) is configured by attaching end members 24Ab, 24Bb, 24Bc, 24Cb, which are elongated plate-like members made of an elastomer material (e.g., rubber) and have obliquely drooping tips, to the ends of plate-like members 24Aa, 24Ba, 24Ca made of a metal material (e.g., stainless steel alloy, etc.).

In addition, each of the anti-scattering covers 24 (24A, 24B, 24C) is formed in a shape that covers the radial outer edge of each of the brushes 20 (20L1, 20L2, 20R1, 20R2) by a predetermined dimension (for example, about 10 to 20 mm) in a plan view. During cleaning, dirt scatters when the bristle bundle 34 with dirt attached thereto separates from the sole of the shoe. In contrast, according to the above configuration, even if dirt scatters, the radial outer edge of the brush 20 (20L1, 20L2, 20R1, 20R2) is covered by the anti-scattering cover 24 (particularly the end members 24Ab, 24Bb, 24Bc, 24Cb), so that the scattered dirt is prevented from going outside the cleaning tank 12 and contaminating the surroundings. In addition, the rubber parts that are attached to the shoes to prevent scattering, as in conventional devices, can be omitted or reduced, eliminating the problem of dirt re-adhering to the next user and improving hygiene.

In addition, the shatterproof cover 24 can also function as a foot vibration prevention member. That is, when a user is washing the soles of their shoes while standing on the footrest 32 with their shoes on, even if the soles come into contact with the rotating brush 20 and the shoes vibrate sideways, the shatterproof cover 24 (particularly the end members 24Ab, 24Bb, 24Bc, and 24Cb) abuts against the shatterproof cover 24, stopping the vibration. Therefore, the user can stably wash the soles of their shoes while standing on the footrest 32 with both feet and wearing their shoes.

Furthermore, the cleaning tank 12 is provided with a fixed foot rest 38. Specifically, a fixed foot rest 38L1 is provided in front of the left brush 20L1, a fixed foot rest 38L2 is provided between the left brushes 20L1 and 20L2, and a fixed foot rest 38L3 is provided behind the left brush 20L2. Also, a fixed foot rest 38R1 is provided in front of the right brush 20R1, a fixed foot rest 38R2 is provided between the right brushes 20R1 and 20R2, and a fixed foot rest 38R3 is provided behind the right brush 20R2. As an example, each fixed foot rest 38 (38L1, 38L2, 38L3, 38R1, 38R2, 38R3) is formed using a metal material (e.g., stainless steel alloy, etc.) in a shape capable of supporting a load, such as an L-shaped, U-shaped, rectangular, or annular cross section. With this, when a user is standing on the footrest 32 with their shoes on and cleaning the soles of their shoes, the footrest 32 and the fixed footrest 38 can support the user's body. Therefore, even if the sole of the shoe comes into contact with the rotating brush 20, the user's feet do not wobble and the user can stand in a stable position. Note that the fixed footrest 38 may be omitted in part or in its entirety (not shown).

Next, as described above, the brush 20 is configured so that the base plate 30 rotates in a horizontal plane. In this embodiment, the lower surface 30b of each base plate 30 of each brush 20 is configured to be arranged in the same horizontal plane. Furthermore, the bottom surface 12x of the cleaning tank 12 facing the lower surface 30b of each base plate 30 is configured as a substantially horizontal plane (however, the entire bottom surface 12x does not need to be a horizontal plane). Here, at the central position in a plan view sandwiched between the left and right brushes 20 on both the left and right sides, i.e., the left brushes 20L1, 20L2 and the right brushes 20R1, 20R2, a dirt receiving groove 26 is provided on the bottom surface 12x of the cleaning tank 12, which is dug downward. As an example, the dirt receiving groove 26 has a width dimension in the left-right direction of about 50 mm, and the cross section opening upward is formed in a gutter shape such as a U-shape, a U-shape, or a V-shape.

In addition, the amount of cleaning water stored in the cleaning tank 12 is set so that the lower surface 30b of the base plate 30 is submerged (but not the upper surface 30a) (the set water level is indicated by a dashed line in FIG. 5). Specifically, the cleaning tank 12 is configured to adjust the water level by overflow. In addition, to prevent an oversupply of cleaning water, a flow rate regulator (e.g., a constant flow valve) is provided in the piping path communicating with the delivery pipe 22 to set an upper limit on the supply of cleaning water (not shown).

Furthermore, as described above, the two left brushes 20L1, 20L2 are configured to rotate in the same direction, the two right brushes 20R1, 20R2 are configured to rotate in the same direction, and the left brushes 20L1, 20L2 and the right brushes 20R1, 20R2 are configured to rotate in opposite directions.

In this embodiment, the brush 20 is configured so that the base plate 30 rotates in a horizontal plane, which provides the effect of allowing the user to clean the soles of their shoes while standing on the footrest 32 with their shoes on. However, on the other hand, the bottom surface 12x of the cleaning tank 12 is configured as a substantially horizontal surface to correspond to the configuration of the brush 20 (base plate 30). Normally, if the bottom surface 12x of the cleaning tank 12 is a substantially horizontal surface, dirt that falls there tends to accumulate, which not only makes cleaning time-consuming but also creates the problem of it being easily unsanitary.

To solve this problem, as described above, the bottom surface 12x of the cleaning tank 12 is provided with a dirt receiving groove 26 at the center of the brushes 20 on both the left and right sides, and cleaning water is supplied while the lower surface 30b of the base plate 30 is immersed. Furthermore, the two left brushes 20L1 and 20L2 are rotated in the same direction, and the two right brushes 20R1 and 20R2 are rotated in the same direction, and the left brushes 20L1 and 20L2 and the right brushes 20R1 and 20R2 rotate in opposite directions (as described above, it is also possible to rotate each brush 20 in the opposite direction). This allows a water flow (indicated by the dashed arrow in FIG. 4) to be generated in the cleaning water (wastewater) that remains on the bottom surface 12x in the cleaning tank 12. Therefore, this water flow guides the dirt contained in the cleaning water (wastewater) and allows it to fall into the dirt receiving groove 26 and be collected, making it easier to clean the dirt. It also reduces dirt inside the cleaning tank 12, especially on the bottom surface 12x, improving hygiene.

In this case, a problem occurs in that the water flow is stagnant and dirt easily accumulates at the four corners 12a-12d of the rectangular area in plan view where the left brushes 20L1, 20L2 are provided on the bottom surface 12x of the cleaning tank 12, and at the four corners 12e-12h of the rectangular area in plan view where the right brushes 20R1, 20R2 are provided. In contrast, as shown in Figure 4, the cleaning tank 12 according to this embodiment is provided with plate-shaped flow control plates 40a-40c and 40e-40g that are erected from the bottom surface 12x at some positions (12a-12c and 12e-12g) of the four corners 12a-12h (or all positions). These flow control plates are arranged to connect two sides that sandwich the corners.

With this configuration, flow control plates 40a-40c, 40e-40g are placed in locations where the water flow is stagnant and dirt is likely to accumulate, making it possible to control the water flow so that it does not stagnate, and preventing dirt from accumulating. This makes it possible to reduce dirt inside the cleaning tank 12 (especially in the corners on the bottom surface 12x), making cleaning easier and improving hygiene.

As a further advanced configuration, as shown in FIG. 10, the shoe sole cleaning device 1 according to this embodiment can be connected in a plurality of units (two units are shown as an example, but the present invention is not limited to this) in the front-rear direction. This allows the user to move forward (or backward) in sequence over the cleaning tanks 12 arranged side by side to clean the soles of shoes. In other words, the upper part of the cleaning tank 12 is configured as a passage. In this case, the cleaning tank 12 can be configured to have as few steps as possible other than the outer frame parts at the front and rear positions, thereby realizing a configuration that makes it easy to move around. For example, when one unit is installed, a problem may occur that the more users there are, the longer the waiting time for cleaning becomes. However, with the above configuration, it is possible to move users in sequence and shorten the waiting time. Furthermore, a configuration can be realized in which the number of units can be increased or decreased flexibly depending on the number of users and the situation of the installation location. In this way, a configuration in which multiple units are connected to each other so that a state of high dirtiness is gradually transitioned to a state of high cleanliness, or a configuration in which a device mainly for removing dirt and a device mainly for sterilization are connected to each other may be used.

As explained above, according to the present invention, it is possible to realize a shoe sole cleaning device that has high cleaning power even for soles with complex shapes and is easy to clean, compared to conventional shoe sole cleaning devices. In particular, it is possible to prevent dirt from the sole from remaining on the bristles of the brush, which prevents dirt from re-adhering to the next user and improves hygiene. In addition, the user can clean the soles of both feet at the same time and in a stable position. This makes it possible to shorten the cleaning time. Furthermore, it is possible to extend the service life of the brush.

The present invention is not limited to the above-described embodiments, and various modifications are possible without departing from the scope of the present invention.
