Description

[Detailed Description of the Invention] -Field of Industrial Application- This invention relates to a cleaning tool, and relates to a cleaning tool having a structure particularly suitable for wiping off sweat etc. scattered on the floor of a gymnasium during a competition. .

- Background of the technology - In extreme competitions held indoors such as volleyball, the sweat of the players scatters on the floor, and in modern gymnasiums where the floor is coated with various types of chemical coatings, the sweat scattered on the floor The surface becomes extremely slippery, which can impede competition and cause athletes to fall.

- Conventional technology and problems - Therefore, the moisture from the floor surface is generally wiped off with a motsup during the downtime of the competition, but conventional cleaning tools such as motsupu cannot remove moisture sufficiently. Cleaning takes time due to repeated wiping, which may delay the restart of the competition, and wiping with a mop causes water droplets on the floor to become a thin film and spread, making the floor more slippery. There was a problem.

-Purpose of the Invention- This invention was made with the aim of solving such problems, and provides a cleaning tool that can efficiently remove moisture scattered on the floor of a gymnasium with a simple operation. This is what we are trying to provide.

-Structure of the Invention- To explain using the reference numerals of the illustrated embodiments, the cleaning tool of the present invention has a roll 3 mounted on a U-shaped support frame 2, and the roll 3 is made of paper or nonwoven fabric. A water-absorbing sheet 4 such as
The roll 3 is mounted on the support frame 2 via a one-way clutch 8 or the like so as to be freely rotatable in only one direction.

-Function- The cleaning tool of the present invention configured as described above is normally used by being attached to the tip of the handle 1 via the support frame 2. 2. Description of the Related Art Conventionally, a cleaning tool is known in which a rotating roll is mounted on a support frame at the tip of a handle and the roll is rolled on a floor surface. However, when the rolls are rolled, it is difficult to sufficiently remove water droplets from the floor surface, even if a water-absorbing sheet is attached to the outer periphery of the rolls. The cleaning tool of the present invention differs from such conventional cleaning tools in that when the roll 3 is pushed in the non-rotating direction, the water-absorbing sheet 4 wrapped around the roll 3 rubs against the floor surface 20. This removes moisture from the floor surface 20. In view of the fact that once the sheet 4 absorbs water, the water-absorbing portion P becomes unable to absorb water thereafter, the roll 3 is mounted rotatably in only one direction, and the roll 3 is rotated in the rotatable direction. By pushing it, the water-absorbing sheet 4 wound around the roll 3 is rotated, and the roll 3 is again pushed in the non-rotating direction so that subsequent cleaning can be performed with the newly fed sheet portion Q. This is what I did.

Further, since the used portion of the sheet 4 wound around the roll 3 can be easily cut off, cleaning work is always performed using a new sheet portion in combination with the sheet feeding operation by the rotation of the roll 3. Therefore, moisture on the floor surface 20 can be removed extremely efficiently. It is preferable that a synthetic resin film or the like is attached to the back surface of the water-absorbing sheet 4 wrapped around the roll 3 to prevent moisture absorbed by the outer sheet from seeping into the inner sheet.

-Embodiment- Fig. 1 and Fig. 2 are views showing an embodiment of the present invention, in which Fig. 1 is a perspective view and Fig. 2 is a sectional view showing a roll mounting structure. In the figure, 1 is the handle, 2 is a U-shaped support frame fixed to the tip of handle 1, and 3 is the support frame 2.
4 is a water-absorbing sheet wound around the row 3, and 5 is a perforation for cutting the water-absorbing sheet 4.

As shown in FIG.
7, one support cone 6 is
It is rotatably supported in only one direction via a one-way clutch 8, and the other support cone 7 is mounted and biased in the axial direction by a compression spring 9. 10 is a bearing housing to which the support frame 2 is fixed; 11 is a clutch shaft supported by a one-way clutch 8 and rotatable in only one direction; 12 is a support cone 6
This is a pin that connects the clutch shaft 11 and the clutch shaft 11 so that they cannot rotate with each other and cannot move in the axial direction.

13 is a cylindrical member fixed on the opposite side of the support frame 2; 14 is a long hole provided in the axial direction of the cylindrical member 13;
15 is a sliding shaft loosely fitted into the cylindrical member 13, 16 is a pin that is set up on the sliding shaft 15 and is loosely fitted into the elongated hole 14, 17 and 18 are spring holders, and 19 is a ball bearing. The compression spring 9 biases the sliding shaft 15 in its advancing direction, and the engagement between the elongated hole 14 and the pin 16 prevents the sliding shaft 15 from rotating and changes its advanced and retreated positions. regulated. The support cone 7 is rotatably attached to the tip of the sliding shaft 15 by a ball bearing 19.

The roll 3 wrapped with the water-absorbing sheet 4 is inserted between the support cones 6 and 7 with the support cone 7 retracted, and is held and mounted between the support cones 6 and 7 by the biasing force of the compression spring 9. Ru. The support cone 6 attached via the one-way clutch 8 allows rotation in only one direction.

FIGS. 3a, 3b, and 3c show a state in which the floor surface 20 is being cleaned using the cleaning tool of the present invention as described above. When the roll 3 is pushed in the direction A, which is the non-rotating direction of the tail 3 holding the handle 1, the roll 3 does not rotate and therefore the floor surface 20
is rubbed by the P portion of the water-absorbing sheet 4 (Fig. 3a). From this state, when the roll 3 is pushed in the direction B, which is the rotatable direction, the roll 3 rotates and the Q portion of the water absorbent sheet 4 comes into contact with the floor surface 20 (the third
If the roll 3 is pushed in the direction A again, the floor surface 20 will be rubbed by the newly fed sheet portion Q (FIG. 3c). That is, by occasionally pushing the roll 3 in its rotatable direction and moving it in its non-rotational direction to rub the floor surface 20, new parts of the water-absorbing sheet 4 are sequentially fed out and cleaned. is carried out, so the floor surface 20
The moisture on the top will be reliably absorbed and removed by the water-absorbing sheet 4.

When the outer layer of the water-absorbing sheet 4 has been used almost evenly, the end of the water-absorbing sheet 4 is cut off from the perforation 5 in FIG. 1, and the second layer of the sheet is used. The cutting of the sheet 4 is carried out using a cutter 22 with saws 21 on the tip side as shown in FIG.
The sheet may be cut along the notches 21 by extending from the support frame 2 to the outer periphery of the sheet 4.

As shown in the illustrated embodiment, the cleaning tool of the present invention includes:
Usually, it is used by attaching it to the tip of the handle 1, but the attachment structure is designed to be removable, so that it is also possible to attach a motsup, such as Duskin, which is traditionally used for wiping, to the tip of the handle 1. If you keep it in place, you can use it for wiping with water or for cleaning normal sand and dust just by replacing the tip.
It is more convenient.

In addition, the sheet 4 may be infiltrated with a cleaning agent in advance,
Alternatively, the cleaning agent is applied to the sheet 4 from the cleaning agent tank installed in the support frame 2, and the floor surface 2
It can also be used as a tool to clean dirt from sheets, and even in this case, a new sheet surface can be fed out by pushing the roll 3 in the rotary direction, so it is easy to operate and efficient. Able to perform cleaning work well.

-Effects of the Invention- As explained above, the cleaning tool of the present invention has a roll mounted on a support frame so as to be rotatable in only one direction, and the water absorption sheet wrapped around the roll removes moisture from the floor surface. It is designed to perform other types of cleaning, and since cleaning is performed by the rubbing action of the water-absorbing sheet, moisture on the floor is reliably removed.
Moreover, since a new sheet portion is fed out by pushing the roll in the opposite direction, there is an effect that moisture on the floor surface can be removed and cleaned in a short time with a simple operation.
