Description

The present invention relates to a cleaning tool that collects dirt, hair, dust, etc.

Patent Document 1 discloses a cleaning tool that includes a cleaning tool body to which a cleaning material is replaceably attached, and a handle that is attached to one end of the cleaning tool body. The cleaning material is formed by planting, adhering, and welding a large number of thread-like fiber materials, and since the cleaning tool body is substantially planar, the cleaning material attached to the cleaning tool body also forms a substantially planar shape.

JP 2007-175144 A

It is easier to clean narrow places if the cleaning body material has width in the thickness direction, and it is even easier to clean narrow places in high places if the cleaning body material is flexible. Therefore, in order to make it easier to clean narrow places in high places, it is better for the cleaning body material to have a flexible shape and thickness, as shown in Figure 2 of Patent Document 1.

One way to make the cleaning material thicker is to increase the length of the thread-like fiber material, but if the thread-like fiber material is made longer, the problem arises that dust and other particles that have gotten into the base of the fiber material become difficult to remove.

Furthermore, if the cleaning tool is used for a long period of time in the flexible shape shown in Figure 2, the flexible protrusion of the cleaning tool body may become curved and deformed, or the flexible protrusion may crack, or even the thin plate-like flexible protrusion may break.

The object of the present invention is to solve the above problems and provide a cleaning tool with a cleaning body attachment part that is flexible and unbreakable, and has a thick cleaning body.

The cleaning tool according to the present invention for achieving the above object is composed of a core part made of a hard material and a cleaning body covered with hair-like bodies, the core part being composed of a grip part to be held by hand and a cleaning body attachment part which is continuous with the grip part and to which the cleaning body is attached, the cleaning body attachment part being composed of a pair of rod-shaped main strip parts parallel to the longitudinal direction of the grip part and first and second connecting parts which connect the pair of rod-shaped main strip parts, the first connecting part being a plurality of connecting pieces which are erected at equal intervals on one side, i.e., the upper side, of the main strip parts. The second connecting portion has a plurality of connecting pieces erected at equal intervals on the other, lower side of the main bar portion, the connecting pieces of the first and second connecting portions have the same shape, the connecting pieces of the first connecting portion and the connecting pieces of the second connecting portion are arranged alternately from the base on the gripping portion side of the main bar portion toward the tip, and the width of the connecting pieces of the first and second connecting portions along the longitudinal direction of the main bar portion is smaller than the gap width between the connecting pieces of the first and second connecting portions along the longitudinal direction of the main bar portion .

The cleaning tool according to the present invention has a flexible and unbreakable cleaning body attachment part, and the cleaning body is thick, so it can efficiently clean narrow areas, and the hairs of the cleaning body can be short, making it easy to remove attached dust from the cleaning body.

The present invention will be described in detail based on the illustrated embodiment. Figure 1 is an exploded perspective view of the cleaning tool storage case of the embodiment and the cleaning tool stored in the cleaning tool storage case, Figure 2 is a perspective view of the cleaning tool storage case in an open state, and Figure 3 is a perspective view of the cleaning tool storage case in a closed state with the cleaning tool stored therein.

The cleaning tool storage case 1 is made up of a first half 1a and a second half 1b that, when closed together, form a rectangular cylinder with a bottom, and is manufactured as a single unit, for example by injection molding using synthetic resin. In addition to a rectangular cylinder, the cleaning tool storage case 1 can also be any other suitable cylindrical shape, such as an elliptical cylinder, and one of the longitudinal ends of the first half 1a and the second half 1b are connected to each other by a thin-walled hinge portion 1c so that they can be opened and closed freely.

A pair of locking mechanisms are formed on the other longitudinal end edges of the first half 1a and the second half 1b, which fit together to maintain the closed state. This locking mechanism is formed of a hook-shaped engaging piece 1d provided on one end and a recessed engaged portion 1e provided on the other end that engages with the engaging piece 1d. The engaging piece 1d may be provided on either the first half 1a or the second half 1b, and similarly, the engaged portion 1e may be provided on either the second half 1b or the first half 1a.

A concave stepped finger hook 1f is provided in the longitudinal center of the first half 1a and the second half 1b, between the pair of locking pieces 1d or the locked parts 1e.

In addition, near one end of the short side perpendicular to the longitudinal end of the first half 1a and the second half 1b, a rectangular frame 1g is formed on the inner surface near the opening described below, into which the piled fabric material 2 is fitted and fixed. The corners of the frame 1g on the opening side are cut to align the direction of the piled fabric material 2 to be fitted.

A wall portion 1h is erected at the other end in the short direction of each of the first half 1a and the second half 1b, and when the first half 1a and the second half 1b are closed, the tips of the wall portions 1h come into contact with each other to form a closed portion, which will be described later.

In addition, in FIG. 1, the hinge portion 1c, which is a connector, is arranged along the longitudinal direction of the first half 1a and the second half 1b, but instead of the hinge portion 1c, a hinge portion may be arranged to connect the tips of the wall portions 1h of the first half 1a and the second half 1b. Furthermore, instead of a structure in which the first half 1a and the second half 1b are connected via a connector, as in these cases, a structure in which the first half 1a and the second half 1b can be separated without providing a connector may be used without any problems.

In addition, if a structure is adopted in which the tips of the walls 1h of the first half 1a and the second half 1b are connected to each other, or a structure in which the first half 1a and the second half 1b can be separated, the locking mechanism will be formed on both longitudinal ends of the first half 1a and the second half 1b.

The raised fabric material 2 is a fabric body with strong directionality due to the raised fabric facing in one direction, and this raised fabric is arranged on both the front and back sides of the raised fabric material 2. The raised fabric may be arranged only on the front side of the raised fabric material 2.

For the raised pile material that generates strong friction in one direction, a material that is oriented in one direction at an angle of, for example, 20° to 70° is used, and filament fibers such as polyester, nylon, acrylic, and acetate are used as the material. In addition, the single yarn fineness of the raised pile material is preferably 5 to 40 denier, but is not limited to this.

The rectangular napped fabric material 2 shown in Figure 2 is napped at the above-mentioned angle toward the inside, and the contact body of the napped fabric material 2 generates a strong frictional force only when it moves from the inside to the outside of the cleaning tool storage case 1.

In addition, cutouts 2a are provided at both ends of one side of the raised fabric material 2, and these cutouts 2a are fitted into the corner cuts of the frame 1g provided along the inner surface near the opening 1i of the first half 1a and the second half 1b, and the raised fabric material 2 is attached to the cleaning tool storage case 1 by fitting them in.

In this way, the inner shape of the frame 1g and the raised fabric material 2 are roughly the same, and these shapes may be asymmetrical with respect to the center line, which is perpendicular to the direction in which the cleaning tool 3 is inserted and removed from the cleaning tool storage case 1. In other words, the cutout 2a of the raised fabric material 2 and the frame 1g may have only one set of corner cuts, or may have recesses and protrusions instead of corner cuts.

By adopting this shape, the pile fabric material 2 attached to the frame 1g in the correct installation direction is positioned so that a strong frictional force is generated only when the cleaning tool 3 is moved in the direction of being removed from the cleaning tool storage case 1.

When the first half 1a and the second half 1b are closed via the hinge portion as shown in FIG. 3 from the state shown in FIG. 2, the cleaning tool storage case 1 becomes a square tube shape. One end of the square tube shape is an opening 1i for inserting and removing the cleaning tool 3, and the other end of the square tube shape is a closing portion 1j consisting of a pair of walls 1h.

The cleaning tool 3, which is made up of the core part 3a shown in FIG. 1 and the cleaning body 3b attached to the core part 3a, is stored in the cleaning tool storage case 1, which has a rectangular cylindrical shape. The cleaning tool 3 is stored in the state shown in FIG. 3, and the cleaning body 3b, which has dust D attached to its surface, is stored completely within the cleaning tool storage case 1 without being exposed to the outside.

The size of the cross section of the cleaning body 3b is approximately the same as the opening 1i of the rectangular cylindrical cleaning tool storage case 1. The length from the closing portion 1j of the rectangular cylindrical cleaning tool storage case 1 to the piled fabric material 2 is formed to be greater than the longitudinal length of the cleaning body 3b.

Figure 4 is a perspective view of the cleaning tool 3 with the cleaning body removed, and Figure 5 is a perspective view illustrating the state in which the cleaning body is attached to the cleaning tool 3. Figure 6 is a plan view of the cleaning tool with the cleaning body attachment part seen through, and Figure 7 is a side view of the cleaning tool with the cleaning body attachment part seen through.

The cleaning tool 3 is composed of a core part 3a made of a hard material such as synthetic resin, and a cleaning body 3b covered with hair-like bodies such as fiber hairs. The core part 3a is composed of a grip part 3c that is held by hand, and a cleaning body attachment part 3d that is connected to the grip part 3c and to which the cleaning body 3b is attached. A locking hole part 3e is formed at the rear end of the grip part 3c so that it can be locked onto a hook or the like during storage.

The cleaning body 3b is composed of a tape-like cleaning strip 3f whose surface is covered with hair-like material such as the aforementioned fibrous hairs. This single cleaning strip 3f is spirally wrapped tightly around the cleaning body attachment part 3d as shown in FIG. 5, to form the cleaning body 3b shown in FIG. 1. The cleaning body 3b may be bag-shaped, and any shape that covers the entire cleaning body attachment part 3d when attached can be appropriately adopted.

The cleaning body attachment part 3d is composed of a pair of rod-shaped main bar parts 3g that are parallel to the longitudinal direction of the grip part 3c, and first and second connecting parts 3h, 3i that connect the pair of main bar parts 3g.

The first connecting portion 3h has multiple connecting pieces 3j erected at equal intervals on one side, the upper side, of the main bar portion 3g, and the second connecting portion 3i has multiple connecting pieces 3j erected at equal intervals on the other side, the lower side, of the main bar portion 3g. The connecting pieces 3j of the first and second connecting portions 3h, 3i extend from a pair of main bar portions 3g in a direction perpendicular to the longitudinal direction of the main bar portions 3g.

The connecting pieces 3j of the first and second connecting parts 3h, 3i have the same shape and are approximately semicircular. The first and second connecting parts 3h, 3i can be appropriately shaped with a curved outer shape such as a semi-elliptical ring, semi-disk, or semi-elliptical disk.

The connecting pieces 3j of the first connecting portion 3h and the connecting pieces 3j of the second connecting portion 3i are arranged alternately from the base of the gripping portion 3c side of the main bar portion 3g to the tip. In other words, the connecting pieces 3j of the second connecting portion 3i are arranged on the main bar portion 3g in the gaps between the connecting pieces 3j of the first connecting portion 3h, and the connecting pieces 3j of the first connecting portion 3h are arranged on the main bar portion 3g in the gaps between the connecting pieces 3j of the second connecting portion 3i.

In this way, by providing gaps between the connecting pieces 3j of the first connecting part 3h and gaps between the connecting pieces 3j of the second connecting part 3h, the cleaning body attachment part 3d can be flexibly bent in the vertical direction of the first connecting part 3h and the second connecting part 3i.

In addition, by arranging the first connecting portions 3h and the second connecting portions 3i alternately on the main strip portion 3g, when the cleaning body attachment portion 3d is bent, the extending portions of the main strip portion 3g can be reinforced by the connecting pieces 3j. Therefore, even if the cleaning body attachment portion 3d is repeatedly bent, the main strip portion 3g will not crack or break.

In addition, because the connecting piece 3j is approximately semicircular, even if a cleaning body 3b with short hairs is attached to the cleaning body attachment part 3d, the entire cleaning body 3b will have a thickness. Therefore, the hairs of the cleaning body 3b can be short, and dust D does not become deeply entangled in the hairs, so the frictional force of the piled fabric material 2 can be sufficient to remove dust D attached to the surface of the cleaning body 3b.

When cleaning using the cleaning tool 3, the handle 3c of the cleaning tool 3 is grasped by hand and the cleaning tool 3 is pulled out from the cleaning tool storage case 1. When the cleaning body 3b of the cleaning tool 3 is completely stored inside the cleaning tool storage case 1 and the handle 3c of the cleaning tool 3 is grasped by hand and the cleaning tool 3 is pulled out from the opening 1i of the cleaning tool storage case 1 toward the outside, the outer peripheral surface of the base of the cleaning body 3b of the cleaning tool 3 comes into contact with the napped fabric material 2 of the cleaning tool storage case 1, and a strong frictional force is generated between the cleaning body 3b and the napped fabric material 2.

Due to this frictional force, the dust D adhering to the surface of the cleaning body 3b is peeled off onto the napped fabric material 2 side, and only the clean cleaning body 3b is exposed to the outside of the cleaning tool storage case 1. When the cleaning tool 3 is completely pulled out from the cleaning tool storage case 1 to the outside, the entire cleaning body 3b is in a clean state. The dust D peeled off onto the napped fabric material 2 side remains inside the cleaning tool storage case 1 and does not scatter to the outside from the cleaning tool storage case 1.

Figure 8 is a side cross-sectional view of the cleaning tool 3 with the cleaning body 3b pressed against the object to be cleaned, for example, a floor surface F. When the cleaning body attachment part 3d is pressed against the floor surface or the like, it is possible to bend the cleaning body attachment part 3d until the tops of the connecting pieces 3j of the first connecting part 3h come into contact with each other.

By sliding the cleaning body 3b along the floor surface F while bending the cleaning body attachment portion 3d, it is possible to efficiently collect dust D on the floor surface F and to cause dust D to adhere to the surface of the cleaning body 3b.

Furthermore, the gap within the semicircular rings of the first and second connecting parts 3h and 3i makes them more easily deformed in response to pressure from above, so that when cleaning narrow spaces, it is possible to insert the cleaning body 3b while deforming the cleaning body attachment part 3d.

In this way, the cleaning tool 3 of this embodiment has a flexible cleaning body attachment part 3d that is not easily damaged, and the cleaning body 3b has a thickness, so that it is possible to efficiently clean narrow cleaning areas, and the hairs of the cleaning body 3b can be short, making it easy to remove attached dust D from the cleaning body 3b.
