Brush provided with retractable bristles to facilitate removal of tangled hair strands
A brush includes a brush body, a plurality of bristles, an operating member, and a biasing member. The brush body includes an upper wall, a lower wall that is aligned with the upper wall along a transverse direction, and that is movable relative to the upper wall, and a guiding member that extends upward from the lower wall through the upper wall. The bristles are mounted on a bristle-mounting surface of the upper wall, and are extendible through the bristle-extension apertures in the lower wall. The operating member is connected to the guiding member, and is operable to move the lower wall relative to the upper wall between upper and lower positions. The biasing member restores the lower wall from the lower position to the upper position.
1. Field of the Invention
The invention relates to a brush, more particularly to a brush provided with retractable bristles to facilitate removal of tangled hair strands therefrom.
2. Description of the Related Art
As shown in
By turning the controlling member 142 clockwise, the bristle-holding element 131 moves upward along the guiding members 141, so that the bristle-holding element 131 is moved away from the combing wall 111, and the bristles 43 are retracted into the brush body 11, thereby leaving tangled hair strands on the combing wall 111 to facilitate the removal of the tangled hair strands.
Although the aforesaid brush can facilitate the removal of tangled hair strands, the operation of turning the controlling member 142 while holding onto the handgrip 12 is awkward and is not ergonomic for the user.
SUMMARY OF THE INVENTIONTherefore, the object of the present invention is to provide a brush with retractable bristles to facilitate the removal of tangled hair strands, wherein the operating action for retracting the bristles into a brush body is a pressing action.
According to the present invention, there is provided a brush that includes: a brush body including an upper wall, a lower wall that is aligned with the upper wall along a transverse direction, and that is movable relative to the upper wall between upper and lower positions, and a guiding member that extends upward from the lower wall through the upper wall, the upper wall having a bristle-mounting surface, the lower wall being formed with a plurality of bristle-extension apertures; a plurality of bristles that are mounted on the bristle-mounting surface of the upper wall, and that extend through the bristle-extension apertures; an operating member disposed above and spaced apart from the upper wall, and connected directly to the guiding member so as to be co-movable with the lower wall relative to the upper wall in the transverse direction, and to move the lower wall from the upper position to the lower position when pressed downward in the transverse direction; and a biasing member for restoring the lower wall from the lower position to the upper position.
BRIEF DESCRIPTION OF THE DRAWINGSOther features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiment with reference to the accompanying drawings of which:
As shown in
The brush body 2 includes an upper wall 21, a lower wall 22 that is aligned with the upper wall 21 along a transverse direction (X), and a guiding member 23. The upper wall 21 has a grip-mounting surface 211 and a bristle-mounting surface 212. The grip-mounting surface 211 is formed with a protruding base 213. The base 213 is formed with a recess 214, and a stud 216 that extends into the recess 214. The upper wall 21 is formed with two guiding slots 215 that are parallel to the transverse direction (X), and that extend through the grip-mounting surface 211, the bristle-mounting surface 212, and the protruding base 213. The lower wall 22 has an inner surface 221 and a combing surface 222, and is formed with a plurality of bristle-extension apertures 223 extending through the inner surface 221 and the combing surface 222. In this embodiment, the bristle-extension apertures 223 are in the form of elongated slots parallel to the transverse direction (X). The guiding member 23 is formed on the inner surface 221 of the lower wall 22, and includes two guiding plates 231 that extend from the inner surface 221 through the guiding slots 215, respectively.
The handgrip 3 is connected to the grip-mounting surface 21 of the brush body 2 to serve as a medium for the user to grasp.
The bristle unit 4 includes a plurality of bristles 41 that are mounted on and that are arranged in rows on the bristle-mounting surface 212 of the upper wall 21 corresponding to the bristle-extension apertures 223 in the lower wall 22.
The operating member 5 is disposed above and is spaced apart from the upper wall 21. The operating member 5 has a bottom surface 51 that is formed with an annular protrusion 52, and two hooks 53. The annular protrusion 52 is aligned with the recess 214 in the grip-mounting surface 211, while the hooks 53 are connected respectively to the guiding plates 231 in a snap engaging manner so as to be co-movable with the lower wall 22 relative to the upper wall 21 in the transverse direction (X).
The biasing member 6 extends into the recess 214 in the grip-mounting surface 211 and the annular protrusion 52, and has a lower end 61 that is sleeved on the stud 216 of the grip-mounting surface 211.
As shown in
As shown in
The following are some of the advantages attributed to the brush according to the present invention:
The principle of the present invention is the same as that disclosed in U.S. Pat. No. 6,681,775, which involves retraction of the bristles 41 by virtue of relative movement between the lower wall 22 and the upper wall 21, so that tangled hair strands are left on the combing surface 222, thereby facilitating the removal of tangled hair strands. However, the operating action by the user according to this invention is a pressing action, so that it meets the ergonomic needs of the user.
While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation as to encompass all such modifications and equivalent arrangements.
Claims
