Description
VACUUM CLEANER HAVING AN APPARATUS FOR FIXING A CORD
The present invention relates to a vacuum cleaner, and more particularly to a vacuum cleaner having an apparatus for fixing a cord.
A vacuum cleaner is an apparatus for sucking dust and impurities by suction power which is generated by a blower assembly which is installed therein.
The vacuum cleaner comprises a body having wheels mounted at both sides thereof, a dust collecting chamber which is installed at an inside of the body for collecting dust and impurities, a trash bag which is installed at an inside of a dust collecting chamber, a flexible hose which is connected to an inlet hole of a dust collecting chamber, a brush head assembly which makes contact with a floor, for sucking dust and impurities, and a cord for transmitting electric power to the vacuum cleaner.
Generally, the vacuum cleaner is powered by a DC current power supplied through a battery accommodated in the vacuum cleaner or by an AC current power which is supplied through a power generator. Accordingly, in the vacuum cleaner which is powered by AC current power, it is necessary to use a power cord which is either fixedly or releasably coupled to the vacuum cleaner to supply electric power to the vacuum cleaner.
FIG 1. illustrates a general structure of a canister type vacuum cleaner 100. The vacuum cleaner 100 comprises a body 110, a brush assembly 120 which is separated from the body 110, and an elongated conduit 130 and a flexible hose 140 connecting the brush assembly 120 with the body 110. A reel apparatus(not shown) for winding and extracting the cord(not shown) is installed at an inner side of the body 110.
U.S. Patent NO. 5,622,243 which is issued to Sang-Bo Kang. entitled "cord winder for a vacuum cleaner" and assigned to the assignee of the present invention discloses an apparatus for fixing a cord of a vacuum cleaner. Kang's cord winder is shown in FIG. 2.
As illustrated, a cord winder 200 includes a reel 232 within a reel chamber 230 defined in a body 110 of the vacuum cleaner 100. A reel torsion spring member (not shown) is installed within reel 232 for applying a clock-wise biasing force to reel 232.
A button 222 is provided to a rear end portion of an upper surface of the body 110. The button 222 has an extended upper portion 220, is integrally formed with the upper surface of the body 110, and has a curved rear portion 223 forming one portion of the rear surface of the body 110.
A pivot tab 217 extends in the downward direction from a front portion of the button 222. A pivot pin 216 penetrates into the pivot tab 217 so as to permit button 222 to be swung about pivot pin 216.
An actuator rod 226 extends in the downward direction at a rear portion of the pivot tab 217. A compression coil spring 218 is installed between the pivot tab 217 and the actuator rod 226 so that a counter-clock-wise biasing force is exerted upon the button 222 by the compression coil spring 218. The actuator rod 226 penetrates the actuator rod hole 239 which is formed in the rear end of a ceiling 238 of the reel chamber 230. An inclined surface 226a is formed to a lower end portion of the actuator rod 226.
Meanwhile, a friction strip 234 is attached to the inner surface of the ceiling 238 of the reel chamber 230, and a guide member 240 is installed to an upper portion of a side wall 231 of the reel chamber 230. The guide member 240 has a shape of a hollow square pillar and defines a guide channel 240a having a rectangular section therein. A stopper rod 212 is inserted in the guide channel(not shown) and is engaged with the actuator rod 226.
The stopper rod 212 has an inclined surface 212a which is formed at a rear end portion thereof and makes contact with an inclined surface 226a of the actuator rod 226.
A stopper wheel 214 is installed at a front portion of the stopper rod 212 and is placed between the outer periphery of reel 232 and friction strip 234 to prevent a revolution of the reel 232. The stopper wheel 214 is rotatably coupled to the stopper rod 212 by the stopper pin 215 penetrating the stopper wheel 214.
A vertically-elongated first branch hole 242 is formed in a lower surface of the stopper rod 212, and a second branch hole 246 corresponding with the first branch hole 242 is formed in a lower surface of the stopper rod 212.
On the other hand, a stopper torsion spring 235 is disposed on the side wall 231 of the reel chamber 230. The stopper torsion spring 235 comprises a first leg portion 237 which is protruded in the upward direction and is inserted into the first branch hole 242, a second leg portion 245 supporting the inner side wall of the cord winder chamber 230, and a circular ring portion 244 which is placed between the first leg portion 237 and the second leg portion 245. The first leg portion 237 penetrates through the first branch hole 242 to be inserted into the second branch hole 246. Accordingly, the stopper torsion spring 235 normally imposes a biasing force in a forward direction upon stopper rod 212.
As illustrated, under the state that the button 222 is not pressed, the button 222 is maintained at its uppermost position by means of the biasing force of the compression coil spring 218, and the stopper rod 212 is maintained at its rear end position by means of the rightward biasing force of the stopper torsion spring 235. At this time, the stopper wheel 214 comes into contact with the friction strip 234 and with the outer periphery of the reel 232 simultaneously, thereby preventing the clock-wise rotation of the reel 232.
When the user presses button 222, the actuator rod 226 goes downward. Then, the inclined surface 226a of the actuator rod 226 comes into contact with and slides along the inclined surface 212a of the stopper rod 212. At this time, the stopper rod 212 is pushed leftward, and the stopper wheel 214 rolls leftward along the friction strip 234. Thus, the contact between the stopper wheel 214 and the reel 232 is released.
In this case, the reel torsion spring(not shown) exerts its clock-wise biasing force upon the reel 232. Therefore, the reel 232 is rotated clock-wise by the biasing force of the reel torsion spring(not shown) so as to wind a cord 224 on the reel 232.
When the user stops the pressing of the button 222, the button 222 ascends by the biasing force of the compression coil spring 218. Then, the actuator rod 226 ascends. At this time, the stopper rod 212 is pushed in the rightward direction by the clock-wise biasing force of the stopper torsion spring 235. Also, the stopper wheel 214 rolls along the friction strip 234 to come into contact with the friction strip 234 and with the outer periphery of the reel 232 simultaneously, thereby preventing the clock-wise rotation of the reel 232.
However, in case of using the cord fixing apparatus, a structure of the cord winder is complicated, so it takes a long time to assemble the cord fixing apparatus, and a lot of components are required, so the manufacturing cost thereof is increased.
Furthermore, even when just one of the components thereof is broken, the cord winder cannot be used.

FIG. 3 illustrates a cord fixing apparatus 380 of a vacuum cleaner 300 according to the present invention. As illustrated in FIG. 3, the vacuum cleaner 300 has a body 310 having wheels 320 mounted at both sides thereof, a brush assembly 340 connected to the body 310 through a flexible hose 330 and making contact with a floor for sucking dust and impurities, a blower assembly 350 which is installed at an inner side of the body 310 for generating a suction force, an extensible cord 360 for supplying an external electric power to the blower assembly 350, and a reel 370 installed at an inner side of the body 310, for winding the cord 360.
When the user carries out a cleaning work by using the vacuum cleaner 300, it is necessary to fix the cord 360 to the body 310. Accordingly, a fixing rib 380 for fixing the cord 360 is formed at the rear wall 305 of the body 310 of the vacuum cleaner 300.
Generally, the fixing rib 380 for elastically fixing the cord 360 is formed adjacent to the opening for the cord 360 which is formed at a rear wall 305 of the vacuum cleaner 300.
As illustrated in FIGs. 4 and 5, the fixing rib 380 is integrally formed at a rear wall 305 of the body 310 and has a groove 384 for receiving the cord 360 which is formed in a longitudinal direction of a front side 386 of the fixing rib 380. The groove 384 of the fixing rib 380 has a width smaller than a diameter 388 of the cord 360. The fixing rib 380 is made of an elastic material for elastically receiving the cord 360. The groove 384 of the fixing rib 380 is provided at both side walls 387 thereof with a pair of projections 382 extending toward a center of the groove 384, for preventing the cord 360 from separating from the groove 384 of the fixing rib 380.
FIGs. 6 and 7. illustrate another embodiment of the present invention. The fixing rib 390 which is formed at a rear wall 305 of the body 310 has a horizontal plate 392 which is integrally formed with the rear wall 305 of the body 310 and is protruded therefrom at an angle of 90 degrees, and a vertical plate 394 integrally formed at an end portion of the horizontal plate 392 and vertically protruded upwards therefrom. A groove 396 for receiving the cord 360 is formed between the vertical plate 394 and the rear wall 305 of the body 310.
The horizontal width(X) of the groove 396 is obtained through a following formula: 0.9d < X < id. That is, the horizontal width(X) of the groove 396 should be smaller than the diameter 388 of the cord 360 and should be over 90% of the diameter 388 of the cord 360 so that the cord 360 can be fixed in the groove 396.
Furthermore, a vertical height(Y) is obtained through the following formula: 0.5dI Y. That is, the vertical height(Y) of the groove 396 should be over 50% of the diameter 388 of the cord 360 so that the cord 360 can be fixed in the groove 396.
FIGs. 8 and 9 illustrate another embodiment of the present invention. The fixing rib 410 is formed at an upper surface 307 of the rear end portion of the body 310 and is made of an elastic material.

The semicircular head portion 402, the semicircular bottom portion 406 and the flank portion 404 are integrally formed with each other The semicircular head portion 402 has a first radius which is identical to a second radius of the semicircular bottom portion 406. The flank portion 404 has a length smaller than the diameter of the cord 360 so that the cord 360 is press-fitted into the flank portion 404.
Hereinafter, the function of the cord fixing apparatus of the vacuum cleaner according to the present invention will be explained.
Refering FIGS, 4 and 5, when the cord 360 is press-fitted into the groove 384, firstly, a lower portion of the cord 360 makes contact with an upper portion of the groove 384 of the fixing rib 380. The downward force for press-fitting the cord 360 into the groove 384 is applied to the upper portion of the cord 360, and then the cord 360 is press-fitted between a pair of the projections 382 which are protrudingly formed at an inner portion of groove 384. At this time, a pair of the projections 382 are opposite away from each other to enlarge the width thereof. Accordingly, the width of the pair of the projections 382 is sufficiently enlarged, and the cord can be passed between the pair of the projections 382. Finally, the cord 360 is placed at an inner side of the groove 384.
When the cord 360 is withdrawn from the groove 384, the procedure is the reverse of the procedure for press-fitting the cord 360. That is, the force for withdrawing the cord 360 from the groove 384 is applied to the lower portion of the cord 360, and the cord 360 is press-fitted between a pair of the projections 382 which are protrudingly formed at an inner portion of groove 384. At this time, a pair of the projections 382 are opposite each other to enlarge the width of the pair of the projections 382. The width of the pair of the projections 382 is sufficiently enlarged, and the cord 360 can be passed between the pair of the projections 382. Finally, the cord 360 is withdrawn from the groove 384.
As described through the embodiments. the cord fixing apparatus of the vacuum cleaner according to the present invention has a simple structure and when the cord is withdrawn from the body, the cord is easily fixed to the cord fixing apparatus.
While the present invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and detail may be effected therein without departing from the spirit and scope of the invention as defined by the appended claims.
