Abstract

To reduce the labor required when using a cleaning tool with a long handle used for cleaning the walls and floors of large steel structures such as the holds of large cargo ships. [Solution] A magnetic roller 4 is attached to a cleaning tool 1 with a long handle, and the pressing force of the tip of the brush against the cleaning surface applied via the long handle 6 is replaced by the magnetic attraction force of the magnetic roller, making it possible to reduce the labor required for the job.

Description

[Technical field]

[0001] This invention relates to a cleaning tool suitable for cleaning floors and walls made of steel plates. [Background technology]

[0002] Long-handled cleaning tools used for cleaning floors or walls (commonly known as deck brushes or floor brushes, and widely used) require the brush tips to be pressed firmly against the surface to be cleaned in order to improve the cleaning effect, so the cleaner must apply pressure to the long handle held with both hands. To clean high up on a wall, the handle needs to be long, but the longer the handle, the more arm strength is required to hold it down, which increases the cleaner's fatigue. On the other hand, magnetic rollers, which are permanent magnets shaped into rollers, roll while being attached to steel plates by magnetic force, and are therefore used to transport steel plates and as drive wheels for self-propelled devices (see, for example, Utility Model Document 1). By attaching a magnetic roller to a cleaning tool with a long handle, the brush tip can be kept pressed against the cleaning surface, and the cleaning worker need not use as much force to hold down the long handle.

[0003] Utility model document 1: Utility model publication No. 03-049182 Summary of utility model Problems that the device aims to solve

[0004] Large cargo ships often have to clean the holds when transferring cargo, etc., and this involves sweeping off cargo residue (mainly powdery residue) that has adhered to the walls and sweeping up the residue from the floor. However, because the cleaning area is large, the cleaning work requires a great deal of effort from the cleaners using long-handled cleaning tools.

[0005] In particular, since the wall surface is high, cleaning tools with long handles are used to reach the high places with the brush. In this sweeping cleaning operation, the force applied to the long handle to press the brush firmly against the cleaning wall surface is increased as the handle becomes longer, which increases the worker's fatigue and reduces the cleaning effect.

[0006] The ceiling of the hold is wide open with a hatch opening, and the top of the wall is often swept down by a cleaning worker standing on the upper deck using a long-handled cleaning tool. In this case, as with cleaning the wall while standing on the floor, the longer the handle, the more force is required to be applied to the handle, which increases the worker's fatigue and reduces the cleaning effect. In addition, the hatch coaming on the edge of the opening forces the cleaner to hold the handle with his or her arms extended, making it even more difficult to apply force.

[0007] When cleaning floors, the handle of a long-handled cleaning tool can be short and it can be used at an angle, making it easy to apply pressure to the brush, but in order to thoroughly sweep and accumulate the residue on the floor so that it is not left behind, it is necessary to press the brush harder than against the wall.

[0008] The above-mentioned problems exist not only in the holds of large cargo ships, but also in large land-based structures (such as storage tanks).

[0009] Large cargo ships are generally made of steel, and the walls and floors of the holds are also made entirely of steel, so the magnetic force of the magnetic roller works effectively. If a magnetic roller is attached close to the brush at the end of a long-handled cleaning tool, the magnetic force can be used to press the brush against the cleaning surface.

[0010] If the magnetic roller is attached immediately behind the tip of the brush, the principle of a lever is established, with the magnetic roller as the fulcrum, the rear end of the handle as the force point, and the brush as the point of action, and the force with which the brush presses against the cleaning surface can be easily adjusted by simply gently moving the rear end of the handle slightly.

[0011] The optimum angle at which the handle is attached to the brush varies depending on whether the surface being cleaned is a wall or a floor, and even if it is a wall, the height of the area being cleaned, so the angle at which the handle is attached may be made adjustable.

[0012] In the case of cleaning walls, the length of the long handle varies depending on the height of the cleaning area, so the handle may be made extendable with a pipe structure. Alternatively, handles of different lengths may be prepared and the overall length may be adjusted by replacing or adding handles.

[0013] When cleaning walls, it is difficult to move the brush vertically in areas below the height of the cleaner's waist, so it is more efficient to turn the long-handled cleaning tool sideways and move it left and right. In this case, the rear end of the long handle (grip) is in a low position, making it difficult to hold, and if a magnetic roller is attached, the axle must be held vertically in order to move it horizontally left and right. Therefore, a long handle with a bent tip may be prepared separately in order to raise the rear end by giving the long handle an oblique angle while holding the axle of the magnetic roller vertically.

[0014] Since the material, hardness, and bristle length of the brush vary depending on the type and amount of cleaning residue, the brush may be attached as an attachment and made replaceable.

[0015] In the above description, the cleaning tool is described as a brush, but depending on the condition of the surface to be cleaned, it may be replaced with a mop or a rubber scaler.

[0016] The force that must be applied to the brush is both a perpendicular force pressing it against the surface to be cleaned and a parallel force moving it over the surface to be cleaned. However, by replacing this perpendicular force with the magnetic attraction force of the magnet roller, the force applied to the long handle can be reduced, significantly reducing the effort required by the cleaner.

[0017] The force required to move the brush over the cleaning surface is equal to the sum of the friction between the brush bristles and the cleaning surface, and the resistance that the attached magnetic roller receives from the cleaning surface, but although the magnetic attraction of the magnetic roller is large, it only occurs in the direction perpendicular to the cleaning surface and does not directly affect the horizontal direction that hinders rolling movement, and only the small rolling friction of the roller acts as a resistance. The brush is moved by pushing or pulling the long handle in the longitudinal direction, so it is easy for the cleaner to apply force, and the increase in labor required to install the magnetic roller is minimal.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Hereinafter, an embodiment of the present invention will be described with reference to Figures 1, 2, and 3. Here, Figure 1 is an overall configuration diagram showing a long-handled cleaning tool with a magnetic roller according to one embodiment of the present invention.

[0020] In one embodiment of the present invention, a long-handled cleaning tool with a magnetic roller 1 has a brush 2 attached to the front of the underside of a T-shaped brush stand 3, magnetic rollers 4 on both rear sides, and a long handle 6 hinged at the end between them. However, to facilitate the replacement of handles of different lengths, a hinged handle insertion socket 5 may be provided at the end of the long handle, and the handle may be inserted into this (with a retaining pin 53 to prevent it from falling off).

[0021] FIG. 2( a ) is a detailed side view of the tip of the cleaning tool. Brush 2 is attached to the front underside of brush base 3 with brush attachment bolts 32 , and magnet roller 4 is attached to bearing member 31 .

[0022] 2(b) is a plan view of the brush base 3 seen from above, and the hinge portion of the handle insertion socket 5 is connected to the brush base 3 with a hinge shaft bolt 51 and fixed with a nut 52. Loosening the nut 52 allows the hinge to rotate freely, and tightening it firmly will fix it at any angle due to frictional force. Note that a knob may be attached to the nut 52 so that it can be tightened and loosened by hand.

[0023] FIG. 2( c ) is a plan view of the tip of this cleaning tool seen from below. A rotating shaft 41 of the magnet roller 4 is attached to a bearing member 31 at the rear of the brush base 3 .

[0024] Figure 3 shows the cleaning work patterns that differ depending on the positional relationship between the cleaner and the surface to be cleaned when using this cleaning tool, (a) shows a cleaner on the floor cleaning the wall surface in an upward and upward direction, (b) shows a cleaner on the upper deck cleaning the wall surface in an upward and downward direction, (c) shows a case where a low area close to the floor of the wall surface is cleaned horizontally, in which case a special long handle with a bent tip is used, and (d) shows a case where the floor surface is cleaned by sweeping it.

[0025] In each of the cases above, the explanations are based on the assumption that the cargo hold is a large cargo ship, but the situation is similar for large structures on land (such as storage tanks), and the same work style is used. [Explanation of symbols]
