Description

The present invention relates to a cleaning brush, and more particularly, to a cleaning brush suitable for cleaning or cleaning narrow gaps such as grooves in tupperware containers.

BACKGROUND ART As a cleaning brush for cleaning or washing a toilet bowl, a sink, etc., there is a known cleaning brush having a large number of brush bristles (see, for example, Patent Document 1). The cleaning brush described in Patent Document 1 includes a handle and a brush member supported at the tip of the handle. The brush member has a rectangular plate-shaped base portion and a large number of brush bristles protruding from one side of the plate-shaped base portion. The plate-shaped base part is folded back at the center in the longitudinal direction, and both ends in the longitudinal direction are attached to the handle with the above-mentioned surfaces provided with brush bristles facing opposite to each other (outside).

When using a cleaning brush with such a configuration, if the object to be cleaned has a relatively wide planar shape, the brush bristles in a planar area of the plate-shaped base part avoiding the folded part at the center in the longitudinal direction are pressed against the object to be cleaned. This allows for efficient cleaning.

On the other hand, when the object to be cleaned is a bent part or a narrow gap such as a groove, the brush bristles of the folded portion at the center in the longitudinal direction of the plate-shaped base part are pressed against the object to be cleaned. However, the plurality of brush bristles protruding from the folded portion extend in a radially dispersed manner, and the tips of the brush bristles are not clustered together but are scattered. Therefore, with the above conventional structure, narrow gaps such as grooves cannot be efficiently cleaned or washed, and there is room for improvement.

Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

1 to 6 show an example of a cleaning brush according to the present invention. The cleaning brush A1 of this embodiment includes a handle 1 and a brush member 2.

As shown in FIGS. 1 to 3, the handle 1 has a rod shape extending in a certain direction (up and down in the figure). In this embodiment, the handle 1 is made by combining and integrally joining two split members (a first member 10A and a second member 10B). The handle 1 has a shape and size suitable for being held in the palm of the hand. An end 11 (upper end in the figure) of the handle 1 is provided with a recess 12, an opening 13, and a locking part 14 for attaching the brush member 2. Details of these elements will be described later.

The brush member 2 has a plate-shaped base portion 21, a large number of brush bristles 22, and a plurality of brush bristles 23, and is attached to the end portion 11 of the handle 1. As shown in FIGS. 6 to 9, the plate-shaped base portion 21 has a long rectangular plate shape extending in a certain direction in its natural state, and is flexible and deformable. The plate-shaped base portion 21 has a first surface 21a and a second surface 21b facing oppositely to each other in the thickness direction. The first surface 21a is generally planar. The second surface 21b is also mostly planar, but has rib shapes that are appropriately raised at the peripheral edge.

The plate-shaped base portion 21 has a first attachment portion 211 and a second attachment portion 212. The first and second attachment parts 211 and 212 are parts for attaching the brush member 2 to the handle 1. The first and second attachment parts 211 and 212 are provided at both ends in the longitudinal direction of the plate-shaped base part 21, and the first and second attachment parts 211 and 212 have brush bristles 22 and brush bristles. 23 is not formed. The first attachment part 211 and the second attachment part 212 are formed with a through hole 211a and a through hole 212a that penetrate in the thickness direction.

A large number of brush bristles 22 each protrude from the first surface 21a of the plate-shaped base portion 21. These brush bristles 22 are approximately uniform in length from the base end (the end on the side of the plate-shaped base portion 21) to the tip, and each has a tapered shape in which the cross-sectional area becomes smaller toward the tip. A large number of brush bristles 22 are evenly provided over substantially the entire area of the plate-shaped base portion 21 except for both ends in the longitudinal direction (first and second attachment portions 211 and 212). More specifically, the large number of brush bristles 22 form a plurality of rows (six rows in the illustrated example) in the width direction of the plate-shaped base portion 21, and are arranged straight along the longitudinal direction.

The plurality of brush bristles 23 protrude from one side surface 21c of a pair of side surfaces 21c and 21d in the width direction of the plate-shaped base portion 21. These brush bristles 23 have a substantially uniform length from the base end (the end on the side surface 21c) to the tip, and each has a tapered shape in which the cross-sectional area becomes smaller toward the tip. The length of the brush bristles 23 is shorter than the length of the brush bristles 22. The plurality of brush bristles 23 are arranged along the longitudinal direction of the plate-shaped base portion 21. These brush bristles 23 correspond to an example of additional brush bristles in the present invention.

The brush member 2 having the above structure is integrally molded from a relatively soft resin material such as polyethylene. To give an example of the dimensions of each part of the brush member 2, the thickness of the plate-shaped base part 21 (excluding the rib-shaped part on the second surface 21b side in the region where the brush bristles 22 are formed) is 1 to 2 mm. The total length of the plate-shaped base portion 21 in the longitudinal direction is approximately 10 to 12 cm, the width of the plate-shaped base portion 21 is approximately 1 cm, the length of the brush bristles 22 is approximately 1 to 2 cm, and the length of the brush bristles 23 is 0. It is about .5 to 1 cm.

Next, attachment of the brush member 2 to the handle 1 will be explained.

As shown in FIGS. 1 to 4, the brush member 2 is folded back at the center in the longitudinal direction of the plate-shaped base portion 21, and both longitudinal ends are attached to the end portion 11 of the handle 1. Specifically, at both longitudinal ends of the plate-shaped base portion 21 (first attachment portion 211 and second attachment portion 212), the first surface 21a is twisted such that it is oriented in a predetermined direction. It can be attached to handle 1 in this state.

As can be understood from FIGS. 3 and 4, in the state in which the plate-shaped base part 21 is folded back at the center in the longitudinal direction, twisted, and attached to the handle 1, the side surface 21c is 21 are close to each other at both ends in the longitudinal direction.

As shown in FIGS. 4 and 10(a), in the handle 1, a pair of openings 13 are formed at the upper end of the first member 10A, which is one of the two halves. Further, a pair of locking portions 14 are formed on the upper inner surface of the first member 10A. When attaching the brush member 2 to the handle 1, the first and second attachment parts 211 and 212 are passed through the pair of openings 13 of the separated first member 10A, and the locking parts 14 are fitted into the through holes 211a and 212a, respectively. (See Figure 10(b)). Thereby, the brush member 2 is held in a predetermined posture by the first member 10A.

"The first surface 21a is oriented in a predetermined direction" at both longitudinal ends of the plate-shaped base portion 21 (the first mounting section 211 and the second mounting section 212) means that the first and second mounting sections This means that the first surfaces 21a (both of the two separate parts) of each of the parts 211 and 212 are oriented in a set direction.

As shown in FIG. 5, in this embodiment, the first surface 21a of each of the first and second mounting portions 211, 212 is arranged in a direction facing the front side of the first member 10A (in the lower part of the figure in FIG. 1, the direction is toward the front of the page). In the present embodiment, the first direction N1 is the direction in which the first surface 21a faces in the first mounting part 211, and the second direction N2 is the direction in which the first surface 21a faces in the second mounting part 212. are in the same direction.

In this case, compared to the case where the plate-shaped base part 21 is folded back and the first surfaces 21a of both longitudinal ends (first and second mounting parts 211, 212) face opposite sides, the first and second Each of the attachment parts 211 and 212 is shown twisted by 90 degrees.

Moreover, in the present invention, unlike the case shown in FIG. The second direction N2 may be different. As shown in FIGS. 11 and 12, for example, the first direction N1 is the direction in which the first surface 21a faces in the first mounting portion 211, and the direction N1 is the direction in which the first surface 21a faces in the second mounting portion 212. The angle α formed by the second direction N2 is 90° or less. Preferably, the angle α between the first direction N1 and the second direction N2 is 45° or less. Note that FIG. 11 shows a case where each of the first and second attachment parts 211 and 212 is twisted by less than 90 degrees. FIG. 12 shows a case where each of the first and second attachment parts 211, 212 is twisted by more than 90 degrees.

Then, the second member 10B is stacked on the first member 10A shown in FIG. 10(b), and the first member 10A and the second member 10B are joined by, for example, welding. In this way, the brush member 2 is attached to the handle 1. At this time, the first and second attachment parts 211 and 212 are inserted into the internal space (recess 12) surrounded by the first member 10A and the second member 10B, which are divided into two parts (see FIG. 5). ).

Next, the operation of this embodiment will be explained.

In the present embodiment, the plate-shaped base portion 21 of the brush member 2 is configured such that the first surface 21a is oriented in a predetermined direction at both ends in the longitudinal direction (the first attachment portion 211 and the second attachment portion 212). It is attached to handle 1 in a bent state. According to such a configuration, the plate-shaped base portion 21 is gently twisted from the vicinity of both ends in the longitudinal direction to the center in the longitudinal direction so that the first surface 21a faces in the predetermined direction. Further, the brush member 2 (plate-shaped base portion 21) attached to the handle 1 has an arch shape that is gently curved as a whole.

According to such a configuration, as can be understood from FIGS. 1 to 4, a large number of brush bristles 22 protruding from the first surface 21a of the plate-shaped base portion 21 are distributed from near both ends in the longitudinal direction to the center in the longitudinal direction. The plurality of brush bristles 22 lined up in the width direction of the plate-shaped base portion 21 are oriented such that their tips are clustered together. Thereby, when cleaning a narrow gap such as a concave groove of a tupperware container, for example, the tip portion of the brush bristles 22 can enter the narrow gap to efficiently clean the narrow gap.

The plate-shaped base portion 21 has first and second attachment portions 211 and 212 in which brush bristles 22 and 23 are not formed at both ends in the longitudinal direction. These first and second attachment parts 211 and 212 are inserted into a recess 12 formed in the end 11 of the handle 1. According to such a configuration, it is possible to appropriately attach the brush member 2 (first and second attachment portions 211, 212) to the handle 1 while maintaining the appearance.

The angle α between the first direction N1, which is the direction in which the first surface 21a faces in the first mounting portion 211, and the second direction N2, which is the direction in which the first surface 21a faces in the second mounting portion 212, is 90 ° or less. According to such a configuration, the first surface 21a is appropriately twisted from the vicinity of both ends in the longitudinal direction to the center in the longitudinal direction of the plate-shaped base portion 21. Therefore, the tips of the plurality of brush bristles 22 arranged in the width direction of the plate-shaped base portion 21 are appropriately densely packed, making it suitable for cleaning narrow gaps and the like.

In this embodiment, the first direction N1 is the direction in which the first surface 21a faces in the first mounting part 211, and the second direction N2 is the direction in which the first surface 21a faces in the second mounting part 212. Same direction. According to such a configuration, as can be understood from FIG. 5, the space (the vertical dimension in the figure) for arranging the first and second mounting portions 211 and 212 inside the handle 1 is reduced. Something happens. Therefore, the end portion 11 (handle 1) for attaching the first and second attachment portions 211, 212 can be made compact.

The brush member 2 has a plurality of brush bristles 23. These brush bristles 23 are provided on one side surface 21c in the width direction of the plate-shaped base part 21, and are lined up along the longitudinal direction of the plate-shaped base part 21. The side surfaces 21c on which the plurality of brush bristles 23 are provided are close to each other at both ends of the plate-like base part 21 in the longitudinal direction when the plate-like base part 21 is twisted and attached to the handle 1. According to such a configuration, as can be understood from FIGS. 1, 2, etc., the large number of brush bristles 22 as a whole are oriented in a predetermined direction (toward the front side of the paper in FIG. 1, and to the left side in FIG. 2). At the same time, the plurality of brush bristles 23 as a whole are also oriented in the predetermined direction. According to such a configuration, by pressing the large number of brush bristles 22 and the plurality of brush bristles 23 against the object to be cleaned, a relatively wide range can be efficiently cleaned or washed.

Although specific embodiments of the present invention have been described above, the present invention is not limited thereto, and various changes can be made without departing from the spirit of the invention. The specific structure of each part of the cleaning brush according to the present invention can be changed in design in various ways.
