Cleaning apparatus

This invention relates to a cleaning apparatus comprising a hand brush and a box.

Description of the Prior Art

A cleaning apparatus used especially for cleaning a toilet bowl comprises a hand brush and a box, and after use, the hand brush is placed in the box in a way to drain water and to dry quickly, and is placed at a corner, for example, of a toilet, is known from DE 199 55 209 A.

A primary structure of such cleaning apparatus is that the hand brush, which comprises a grip bar having a brush part at the head thereof and a flange at the base thereof, is placed in a box such that a periphery of the flange is fit in an upper portion of the box.

In this combination, the lengths of the box and the hand brush are relatively fixed not to contact the head edge of the brush part to the bottom wall of the box. By having the head edge of the brush part float above the bottom wall, the brush part is promoted to drain water contained therein and dries quickly.

Primarily, it is desired that such a cleaning apparatus is smaller in size because if the box in particular is large, the apparatus becomes an obstacle in a narrow space as such as a toilet or a lavatory.

According to the structure of the prior art as described above, the flange is provided at the base portion of the grip, so that a distance between the flange and the head edge of the brush part becomes long, and that a height of the box becomes long as well in order to effectively drain water of the brush part by providing a space between the brush part and the box. This incurs a larger size of the apparatus.

Although it is possible to make the box minor in length by providing the flange near the head of the grip, a base portion of the grip bar becomes heavier unbalancing the weight of the grip bar, which brings the apparatus to easily fall down. Further, it is difficult to handle the hand brush since the flange is provided at the head of the grip.

Therefore, it is an object of this invention to solve the problems the above-described prior art has and to provide a cleaning apparatus which comprises a box smaller in size.

SUMMARY OF THE INVENTION

There is provided a cleaning apparatus which comprises a hand brush 11 and a box 16. The hand brush 11 comprises a thick plate 13 provided with a brush part 12 around an periphery surface thereof, and a grip bar 14 connected to a portion of the periphery surface of the thick plate 13 at the head edge thereof. The grip bar 14 comprises an engage part 15 at each side of a head portion thereof. Each engage part 15 protrudes in an axial direction of the box 16. The box 16 comprises a periphery wall 17 and a bottom wall 18. The periphery wall 17 is provided with engage grooves 19 at an inner surface thereof. Each engage groove 19 receives the corresponding engage part 15 at a position where an head edge of the brush part 12 of the hand brush 11 does not contact with the bottom wall 18.

The cleaning apparatus may be constructed such that the engage groove 19 is beveled by gradually enlarging the width thereof toward an upper direction. The cleaning apparatus may also be constructed as such that two engage grooves 19 are provided adjacently as a pair in an inner surface of the periphery wall 17.

According to the invention, there are obtained various effects. The box can be made smaller in size and is slimed, so that a smaller space is required for a placement of the apparatus. It is easy to drain water contained in the brush part. It performs an good air permeability. The brush part is well dried so that it is sanitary.

DESCRIPTION OF PREFERRED EMBODIMENT

According to an embodiment of the invention, a hand brush 11 comprises a thick plate 13 having a roughly discoidal shape and is provided with a brush part 12 around a periphery surface thereof. A grip bar 14 having a curbed head portion at the head portion thereof is connected to a portion of the periphery surface of the thick plate 13. There is provided an engage part 15 at each side of the head portion of the grip bar 14 along an axial direction of the thick plate 13.

As illustrated in the drawings, the engage part 15 is formed such that the head portion of the grip bar 14 is narrowed in width while providing a step at an opposite side facing the front direction.

Although the brush part 12 is provided around the periphery surface of the thick plate 13 except a portion where the head edge of the grip bar 14 is connected, it is provided radiantly from a center of the discoidally formed thick plate 14, so nearly no portion of the brush part 12 projects in an axial direction of the thick plate 13. Further, the grip bar 14 is formed flat in width except a portion where the engage parts 15 are provided, so that a width of the hand brush 11 is withheld within a width of the thick plate 13, thereby forming a flat and slime figure.

The box 16 comprises a periphery wall 17 and a bottom wall 18 forming a tubular shape having an upper portion widely opened. According to this illustrated embodiment, the box 16 is ellipsoidal and planiform in a plan view having a major axis and a minor axis where the former is 2. 3 times major than the latter. There is provided an engage groove 19 at each inner surface which faces with each other at both sides of the major axis. Each engage groove 19 receives an engage part 15 which enters into the engage groove 19 from the top to the bottom.

Each engage groove 19 comprises a slant wall 20 at each upper side which gradually widens the width length between both slant walls 20 in the upper direction, while it comprises an engage step 21 at the bottom for engaging the engage part 15 on the step 21. In this composition, it is structured that the head edge of the brush part 12 does not contact the bottom wall 18 of the box 16. As illustrated in Figs. 1 and 3, a distance between the head edge of the brush part 12 and the engage part 15 as well as that of the bottom wall 18 and the engage step 21 are both fixed in order to improve a performance in draining water contained in the brush part 12 to dry.

Two engage grooves 19, 19 are provided adjacently at each inner surface of the periphery wall 17 as a pair, forming a mount-shaped step 22 by slant walls 20, 20 of the engage grooves 19, 19.

Therefore, according to this structure, when the hand brush 11 is inserted into the box 16 from the upper portion thereof which is widely open, the engage parts 15, 15, the portions mostly protruded in side directions of the hand brush 11, engage with the engage grooves 19, 19 as they are guided by the slant walls 20, 20 while making contact with the inner walls of the box 16. After the hand brush 11 further moves down, each engage part 15 rides on the corresponding engage step 21.

Further, as described above, both the hand brush and the box 16 are planiform in a plane view, so that while the hand brush 11 is inserted into the box 16, a directivity of the hand brush 11 and the box 16 is regulated as a radial direction of the thick plate 13 of the hand brush 11 forcibly corresponds to a major axis of the box 16.

It is because the head portion of the grip bar 14 of the hand brush 11 is curved a little, and that the brush part 12 makes an contact with the narrow inner walls, which arc directed along the minor axis of the box 16, depending on a direction the hand brush 11 is inserted.

Therefore, as described above, by forming a pair of engage grooves adjacently, despite the planiform hand brush 11 is inserted into the box 16 in either direction, each engage part 15 is guided by the mount-shaped step 22 and successfully engages with the corresponding engage groove 19. For that reason, it is unneeded to adjust a direction of an insertion when inserting the hand brush 11 into the box 16.

Each engage groove 19 is formed in the inner surface of the periphery wall 17 in a vertical direction, so that by engaging the engage part 15 with the engage groove 19, the hand brush 11 is prevented from falling down by loosing its balance even though the engage parts 15, 15 are provided at the head portion of the hand brush 11. Therefore, a height of the box 16 can be held minimum.

The embodiment described above and illustrated in the drawings aims particularly to a brush for a toilet use, but the invention is not limited to such use and is expected to use in any other fields as a cleaning tool.
