- 2. Description of the Prior Art
- Generally, a vacuum cleaner collects dirts or dust in the air by intaking air with a strong suction force which is generated due to the high pressure difference between an interior and an exterior of a body of the vacuum cleaner while the interior is vacuumized by a motor. When air is sucked into/let out of the body of the vacuum cleaner, dirt or dust in the air is filtered out by a filter which is located within the body of the vacuum cleaner. Such a vacuum cleaner is divided into various types such as a canister type, upright type, stick type, and handy type, according to their respective shape.
- Among the above vacuum cleaners, as shown in FIG. 1, the upright type vacuum cleaner has a
brush assembly 2 which is directly connected to the lower portion of a body 1 of the vacuum cleaner. The body 1 and thebrush assembly 2 are connected with each other by a hinge, and can be rotated with each other. A pair ofrollers 3 are disposed on the lower end of the body 1, and a handle portion 4 is formed on the upper end of the body 1. - Meanwhile, albeit not shown in the drawings, there are a motor, filter, etc., located in the body1, and a suction port, and brush drum, etc. are formed at the
brush assembly 2. - In order to clean a certain place with the above vacuum cleaner, a user holds the handle portion4, and moves the body 1 and the
brush assembly 2 connected with the body 1 to his/her desired locations. - When cleaning an area, the user usually tilts the body1 of the upright type vacuum cleaner, and the body leans over the
rollers 3 at the lower end of the body 1. Accordingly, the weight of the body 1 is exerted to the handle portion 4 on the upper end of the body 1, and the user becomes tired when he/she uses the vacuum cleaner for an extended period of time since he/she has to perform the cleaning process under the complete weight of the vacuum cleaner. - The present invention has been developed to overcome the above problem of the related art, and accordingly it is an object of the present invention to provide an upright type vacuum cleaner capable of counterbalancing a partial weight of a body, thereby relieving a user of excessive weight of the body exerted on the handle portion and letting the user perform the cleaning operation for a long period of time without being tired.
- The above object is accomplished by an upright type vacuum cleaner according to the present invention, including: weight counterbalancing means disposed at a connective portion for connecting a body of the vacuum cleaner with a brush assembly in a manner that the body and the brush assembly are rotated on each other, the weight counterbalancing means for counterbalancing a partial weight of the body when the body is inclined.
- The weight counterbalancing means includes a pair of shafts formed on both sides of the body; a pair of shaft positioning portions formed on the brush assembly corresponding to the pair of shafts of the body; holders connected to the respective shaft positioning portions for rotatably supporting the shafts positioned on the shaft positioning portions; and torsion springs each of which having one end fixed at each shaft, and the other end fixed at the brush assembly, for elastically supporting the body in a perpendicular relation with respect to the brush assembly.
- A pair of moving rollers are formed on both rear sides of the brush assembly for a smooth mobility of the vacuum cleaner.
- Accordingly, when a user tilts the body of the vacuum cleaner to perform the cleaning operation, a partial weight of the body is supported by the torsion springs, so the user handles less weight exerted on the handle portion, and is less tired even after a long period of cleaning.
- The above and other objects and the advantages of the present invention will become readily apparent by reference to the following detailed description when considered in conjunction with the accompanying drawings in which:
- FIG. 1 is a perspective view of a conventional upright type vacuum cleaner;
- FIG. 2 is a perspective view of an upright type vacuum cleaner according to a preferred embodiment of the present invention;
- FIG. 3 is an exploded perspective view for showing the main portion of the present invention, i.e., weight counterbalancing means of the upright type vacuum cleaner according to the preferred embodiment of the present invention; and
- FIG. 4 is a side elevation of a brush assembly connecting portion having the weight counterbalancing means according to the present invention.
- FIGS.2 to 4 show an upright type vacuum cleaner according to the preferred embodiment of the present invention.
- As shown in FIGS.2 to 4, the upright type vacuum cleaner according to the present invention includes a
body 10, abrush assembly 20, and weight counterbalancing means 30 formed at a connective part for connecting thebody 10 with thebrush assembly 20 in a manner that thebody 10 and thebrush assembly 20 are rotated on each other, for counterbalancing part of the weight of thebody 10 when thebody 10 is inclined. - The
body 10 includes a vacuum motor, and filter, etc., and ahandle portion 11 is formed at the upper portion thereof. - Further, the
brush assembly 20 includes a suction port (not shown) formed therein, and other components such as a brush drum, etc. Thebrush assembly 20 further includes a pair ofrollers 22 formed at both rear ends for mobility. - Meanwhile, the weight counterbalancing means30 includes a pair of
shafts 32 formed on both sides of thebody 10, a pair of shaft positioningportions 24 formed on thebrush assembly 20 to correspond to the pair ofshafts 32,holders 26 fastened to the respective shaft positioningportions 24 bybolts 28 for rotatably supporting theshafts 32 positioned on the shaft positioningportions 24, andtorsion springs 36 each of which having one end fixed at eachshaft 32 and the other end fixed at thebrush assembly 20 for elastically supporting thebody 10 toward thebrush assembly 20 in a perpendicular direction. - The
shafts 32 are hollow shafts, andspring holders 34 are formed therein. Eachshaft 32 is divided into two semicircular members, and eachspring holder 34 includes a hole into which one end of thetorsion spring 36 is fit. - The shaft positioning
portions 24 are in each semicircle for positioning theshafts 32, and respectively include screw holes formed on both sides thereof. - Further, the
holders 26 include semicircular portions corresponding to the respective semicircular portions of the shaft positioningportions 24, and screw holes formed on both sides thereof. Accordingly, asbolts 28 are passed through the screw holes of theholders 26, and are fastened into the screw holes of the shaft positioningportions 24, theholders 26 are coupled with the shaft positioningportions 24, and support theshafts 32. - Each
torsion spring 36 is fit into eachspring holder 34 formed within eachshaft 32, while one end thereof is fixed in the hole formed in thespring holder 34, and the other end is fixed between theshaft positioning portion 24 and theholder 26. - There is no limit to the shape or material for the
torsion spring 36 as long as the same can stand the required torsional stress, but it is preferable that thetorsion spring 36 is made of a metal coil spring which is wound in a cylindrical fashion. - With the upright type vacuum cleaner according to the present invention, like the conventional vacuum cleaner, the user performs the cleaning operation by pushing or pulling the vacuum cleaner and moving the
brush assembly 20 to the desired cleaning surface while holding the handle provided at thebody 10. The unique feature of the present invention is the weight counterbalancing means for counterbalancing the partial weight of thebody 10, thereby reducing the weight of thebody 10 exerted on thehandle portion 11, when a user tilts thebody 10 to perform the cleaning operation. Such is described in detail below. - When the user tilts the
body 10 at a certain angle, theshafts 32 formed in thebody 10 are rotated on the shaft positioningportions 24 formed in thebrush assembly 20 at the same slanted angle, and accordingly, thetorsion springs 36, whose ends are attached at thespring holders 34 provided in theshafts 32 and the other ends are attached at thebrush assembly 20, are twisted. Since the torsion springs 36 support thebody 10 to be perpendicular to thebrush assembly 20, thetorsion springs 36 support a partial weight of thebody 10. Accordingly, since the torsion springs 36 support the partial weight of thebody 10, the user handles less weight of thebody 10 and is able to perform the cleaning operation more conveniently. - As described above, according to the present invention, since the weight counterbalancing means supports a partial weight of the body, the user can perform the cleaning operation with reduced weight, and accordingly, the user is less tired even after a long cleaning operation.
- As stated above, a preferred embodiment of the present invention is shown and described. Although the preferred embodiment of the present invention has been described, it is understood that the present invention should not be limited to this preferred embodiment but various changes and modifications can be made by one skilled in the art within the spirit and scope of the present invention as hereinafter claimed.
