DETAILED DESCRIPTION OF THE EMBODIMENTS

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to accompanying drawings. In assigning reference numerals to elements in each drawing, it shall be noted that like elements have like reference numerals as much as possible even if illustrated in different drawings.

FIG. 1is a view showing a strip part of a washing brush according to a first embodiment of the present invention,FIGS. 2A and 2Bare views showing a shaft part and a sliding part of the washing brush according to the first embodiment of the present invention,FIG. 3is a view showing the washing brush according to the first embodiment of the present invention, andFIG. 4is a view showing a state where the strip part ofFIG. 3is bent.

Referring toFIGS. 1 to 3, the washing brush according to the first embodiment of the present invention includes a handle part110, a shaft part120, a sliding part130, a strip part140, and a brush part150.

The handle part110is configured such that a user can hold it with the hand.

The shaft part120is connected to the handle part110to extend in a longitudinal direction. Joining parts122and123are formed at a lower end portion of the shaft part120to be joined with the strip part140. In a state where the joining parts122and123are joined with the strip part140, when the user rotates the handle part110to wash a container10, the shaft part120and the strip part140can be rotated together. For this, the joining parts122and123have an oval or polygonal cross section.

The sliding part130is fit over a part of the shaft part120to be able to slide along the shaft part120.

The strip part140is joined to the lower end portion of the shaft part120and a lower portion of the sliding part130. The strip part140may have a long band shape, and has joining parts141and142disposed at the center and both end portions thereof. The joining part141is joined with the lower end portion of the shaft part120, and the joining part142is joined with the sliding part130. For instance, the joining part142has an opening142aand the sliding part130has a protrusion pin132, so that the joining part142and the sliding part130are combined with each other when the opening142ais fit over the protrusion pin132. The way that the strip part140is combined with the shaft part120and the sliding part140may be achieved by various methods known in the technical field. The strip part140may have predetermined rigidity and elasticity.

The strip part140has a cross-sectional shape getting thicker upwards from the lower end portion of the shaft part120. InFIG. 1, lengths of arrows express intensity of power to bend the strip part140. That is, while the strip part140gets thicker upwards from the lower end portion of the shaft part120, a portion adjoining the lower end portion of the shaft part120is bent when small power is applied, and a portion adjoining an upper portion of the shaft part120is bent when stronger power is applied.

Furthermore, the strip part140has a groove143with a predetermined depth adjacent to the joining part142combined with the lower portion of the sliding part130. Such a groove143is to make the portion adjoining the combining part142bent toward a direction that the strip part140spreads, and may be formed on the side facing the shaft part120or on the opposite side of the shaft part120.

The brush part150is attached to the outer surface of the strip part140so as to wash the container10. The brush part150may be an individual member separated from the strip part140and may be attached to the strip part140by adhesive or other adhering means. On the other hand, the brush part150may be formed integrally with the strip part140to protrude from the strip part140.

A position adjusting part can adjust a relative position of the sliding part130relative to the shaft part120while sliding the sliding part130along the shaft part120.

The position adjusting part includes: a plurality of grooves121formed in the shaft part120to be spaced apart from each other at predetermined intervals; and protrusions131formed at both sides of the lower end portion of the sliding part130to be fit to the grooves121. When the user pushes the sliding part130toward the lower end portion of the shaft part120, the protrusions131are fit to the grooves121to adjust the relative position of the sliding part130relative to the shaft part120.

The position adjusting part may be configured such that the protrusions are formed on the shaft part120and the plurality of openings are formed in the sliding part130to be spaced apart from each other. While the sliding part130slides along the shaft part120, the protrusions protrude over the openings so as to limit movement of the sliding part130relative to the shaft part120.

Additionally, when the strip part140is joined to the sliding part130by a fastening member and the fastening member protrudes toward the shaft part120at a predetermined distance, the position adjusting part may provide the shaft part120with proper friction force. Therefore, the fastening member can adjust the relative position for the shaft120by providing the proper friction force while enabling the sliding part130to slide along the shaft part120.

It will be understood by those of ordinary skill in the art that the position adjusting part may be realized by other various ways.

When the position adjusting part adjusts the relative position of the sliding part130relative to the shaft part120, the sliding part130is pressed toward the lower end portion of the shaft part120so that the strip part140is bent to spread outwardly. In addition, the position adjusting part can adjust the level that the strip part140spreads outwardly by adjusting the relative position of the sliding part130relative to the shaft part120.

Referring toFIG. 4, the strip part140is bent outwardly to be suitable for the shape of the inner surface of the cylindrical container10with a narrow mouth so that the user can easily wash the container. The conventional washing brush is inconvenient to wash cylindrical containers with a narrow mouth since the shape of the brush is not variable. However, because the strip part140has the cross-sectional shape getting thicker upwards from the lower end portion of the shaft part120, the strip part140spreads wider when the user holds the washing brush and applies greater power toward the bottom surface of the container10. Therefore, the strip part140of the washing brush gets closer to the inner surface of the container10to wash the container10by the brush part150regardless sizes of the container10.

FIG. 5is a view showing a strip part of a washing brush according to a second embodiment of the present invention,FIG. 6is a view showing the washing brush according to the second embodiment of the present invention, andFIG. 7is a view showing a state where the strip part ofFIG. 6is bent.

In the second embodiment of the present invention, the washing brush includes a handle part210, a shaft part220, a sliding part230, a strip part240, and a brush part250. A detailed description of the handle part210, the shaft part220, the sliding part230and the brush part250will be omitted since they have the same structures as the handle part110, the shaft part120, the sliding part130and the brush part150of the washing brush according to the first embodiment illustrated inFIG. 3.

The strip part240is joined with a lower end portion of the shaft part220and a lower portion of the sliding part230. The strip part240may have a long band shape, and has joining parts241and242disposed at the center and both end portions thereof. The joining part241is joined with the lower end portion of the shaft part220, and the joining part242is joined with the sliding part230. For instance, the joining part242has an opening242aand the sliding part230has a protrusion pin232, so that the joining part242and the sliding part230are combined with each other when the opening242ais fit over the protrusion pin232. The way that the strip part240is combined with the shaft part220and the sliding part240may be achieved by various methods known in the technical field. The strip part240may have predetermined rigidity and elasticity.

The strip part240includes a plurality of grooves243formed in the surface facing the shaft part220to be spaced apart from each other at a predetermined interval, and the grooves243get shallower upwards from the lower end portion of the shaft part220. InFIG. 5, lengths of arrows express intensity of power to bend the strip part240. That is, while the strip part240gets shallower upwards from the lower end portion of the shaft part220, a portion adjoining the lower end portion of the shaft part220is bent when small power is applied, and a portion adjoining an upper portion of the shaft part220is bent when stronger power is applied.

Moreover, because the grooves243are formed to the portion adjoining the joining part242joined to the lower portion of the sliding part230, the portion adjoining the joining part242may be also bent when a predetermined force is applied.

A position adjusting part can adjust a relative position of the sliding part230relative to the shaft part220while sliding the sliding part230along the shaft part220.

Referring toFIG. 7, the strip part240is bent outwardly to be suitable for the shape of the inner surface of the cylindrical container20with a narrow mouth so that the user can easily wash the container. In this instance, because the grooves243formed in the strip part240get shallower upwards from the lower end portion of the shaft part220, the strip part240spreads wider when the user holds the washing brush and applies greater power toward the bottom surface of the container10. Therefore, the strip part240of the washing brush gets closer to the inner surface of the container10to wash the container10by the brush part150regardless sizes of the container10.

FIG. 8is a view showing a strip part of a washing brush according to a third embodiment of the present invention.

Referring toFIGS. 2A and 8, a strip part340is joined to a lower end portion of the shaft part120and a lower portion of the sliding part130. The strip part340may have a long band shape, and has joining parts341and342disposed at the center and both end portions thereof. The joining part341is joined with the lower end portion of the shaft part120, and the joining part342is joined with the sliding part130. For instance, the joining part342has an opening342aand the sliding part130has the protrusion pin132, so that the joining part342and the sliding part330are combined with each other when the opening342ais fit over the protrusion pin132.

The strip part340has a cross-sectional shape getting thicker upwards from the lower end portion of the shaft part120. InFIG. 8, lengths of arrows express intensity of power to bend the strip part340. That is, while the strip part340gets thicker upwards from the lower end portion of the shaft part120, a portion adjoining the lower end portion of the shaft part120is bent when small power is applied, and a portion adjoining an upper portion of the shaft part120is bent when stronger power is applied.

Furthermore, the strip part340has a groove343with a predetermined depth formed in the surface which is adjacent to the joining part342combined with the lower portion of the sliding part130and faces the shaft part120. Such a groove343is to make the portion adjoining the combining part342bent toward a direction that the strip part340spreads, and may be formed on the side facing the shaft part120or on the opposite side of the shaft part120.

Furthermore, the strip part340may have grooves344spaced apart from each other at predetermined intervals. Such grooves344have the same depth, and make the strip part340bent well in order from the lower end portion of the shaft part120.

While the exemplary embodiments of the present invention have been described in more detail with reference to the accompanying drawings, but the present invention is not essentially limited to the exemplary embodiments, and it will be understood by those of ordinary skill in the art that various modifications and equivalents may be made without deviating from the spirit or scope of the invention.
