Definitions

  • This invention relates to a household appliance having rotating or reciprocating heads, such as a rotating or reciprocating cleaning brush, electric toothbrush, massager, or polisher.
  • the household appliances with which the present invention is concerned normally consist of a head or tool attached to directly to a shaft so as to rotate or oscillate therewith, in order to provide some sort of cleaning, brushing, polishing, or massaging effect.
  • the present invention is intended to increase the efficiency of such devices, by splitting the head or tool by which the function of the device is carried out into multiple heads or tools having a differential motion.
  • This has the advantages of (1) offsetting or canceling out the counter-torque effect, thereby making the device easier to handle, (2) generally balancing the forces applied by the device to permit the device to be used on uneven surfaces, edges, and corners, (3) providing a cross- cleaning effect at the point where the different sections of the device move in different directions or at different speeds, and (4) reducing bristle twisting effect in the case of a brush having relatively long bristles.
  • Figures 1-1 and 1-2 of the accompanying drawings illustrate the relationship between "linear speed" and radius in a two layer counter-rotating brush assembly in which the counter-rotating brushes have the same angular speeds
  • Figures 1-3 and 1-4 illustrate the relationship between "linear speed” and radius in a four layer counter-rotating brush assembly
  • Figures 1-5 and 1-8 illustrate the relationship in an eight layer assembly.
  • the linear speed which is the relative instantaneous speed between a bristle and the portion of the surface which is being contacted by the bristle; increases linearly across each of the brush heads while at the interface between brush heads, the linear speed of respectively adjacent bristles on the heads is exactly the same but opposite in direction.
  • the balancing effect improves, with perfect balance being achieved in theory by an infinite number of heads with infinitesimally small differences in radii across the heads (referred to as the infinitesimal balancing effect). While cost of construction will eventually limit the number of heads, the invention in theory enables cross-cleaning and balancing to be made as close to optimum as desired by increasing the number of heads.
  • the present invention seeks to split a single tool or head into multiple heads or tools with differential movement, not in order to increase the area cover during one pass of the device, but to provide a variety of performance improvements, including increasing the intensity of the effect provided by the multiple heads in comparison with a conventional rotating or reciprocating device of like area.
  • the splitting of a single head or tool into concentric or parallel multiple heads or tools arranged for coaxial rotation or side-by-side oscillation according to the present invention not only solves the above-mentioned problems of conventional devices, but also does so without significantly increasing the complexity of the device, since according to preferred embodiments of the invention, a single drive shaft can be used (although the use of a single drive shaft is not necessary to the invention in its broadest form, since the advantages of easier handling and improved cleaning do not depend on the specific mechanical arrangement used to achieve the differential rotation effect).
  • the balancing problem is especially apparent in devices intended to be used on uneven surfaces, such as a car polisher, where the counter torque changes from time to time, and also in devices such as floor buffers which have an odd number of heads, and therefore an inherently unbalanced torque.
  • the cross-cleaning advantage applies even in the case of ordinary linearly reciprocating electric toothbrushes, which one would expect to remove dirt effectively despite the lack of differential motion due to the reversal of motion at the ends of the oscillations.
  • the problem is that either the amplitude of the oscillations is so small that the cleaning tip of the soft bristles will remain relatively stationary even as the brush head moves, or the amplitude will be sufficiently large that the brush head will have moved to another surface before it reverses direction, greatly reducing the cross-cleaning effect provided by the reversal of motion at the end of the oscillations.
  • a household appliance including a rotating head divided into a plurality of coaxially rotatable members having respective contact areas for contacting a surface, and further comprising means for driving at least two of said members at mutually different velocities, said velocities and contact areas of said coaxially rotatable members being selected such that the torques resulting from rotation of said members are substantially balanced, whereby to substantially balance said appliance.
  • the contact areas of the members are selected such that the torques are balanced, we mean that the said contact areas are such as result from calculations of the kind which now follow and which, in the particular case of two concentrically arranged brushes made of the same material and arranged to rotate in opposite directions, result in the outside radius of the inner brush being approximately 0.8 times the outside radius of the outer brush.
  • a similar method may be used to calculate the contact areas of three concentric brushes in an apparatus where the outside radius of the inner brush is a, the outside radius of the middle brush is b and the outside radius of the outer brush is c, with the middle brush rotating in the opposite direction to the inner and outer brushes, and all of the brushes having the same coefficient of friction with respect to a given surface, i.e. being made of the same material.
  • the frictional torque of the inner brush is:
  • the frictional torque of the middle brush is:
  • the frictional torque of the outer brush is:
  • each layer with its own characteristic coefficient of friction may vary as a function of their linear speeds of rotation, i.e. relative to radius).
  • the coefficient of friction of the i th layer as a function of R is f i (R).
  • the frictional torque of the i th layer is:
  • the speed Vn can be positive, negative (i.e., the reverse direction of positive), or zero (i.e., stationary).
  • the number of assemblies or sections and the speeds and directions of individual assemblies or sections may be freely varied so long as the sum of the torques for all of the assemblies approaches the desired level. Since the torques on individual assemblies or sections depends also on the contact areas and materials of the contact surfaces, these factors must be taken into account when selecting the speeds and directions of the individual assemblies.
  • the preferred configuration is as discussed above to rotate adjacent assemblies in opposite directions at substantially the same angular speed, so that the linear speed at the boundaries between assemblies is approximately the same, and to increase the number of assemblies with the overall diameter or area of the contact surface to maximize the number or locations at which cross-cleaning can occur.
  • the assemblies are all rotating in opposite directions at generally the same speed, balancing will be improved for larger diameter contact surfaces if the number of assemblies or sections is increased, i.e., if the number "n" of layers is increased.
  • the appliance may have a head or tool split into three or more assemblies or sections which all rotate coaxially but at different speeds and in the same or different directions.
  • the directions of any individual assembly may be reversed periodically by an electrical or mechanical switching arrangement so that rather than rotating continuously, the individual assemblies may rotate back and forth, and by extending the principles of the first embodiment to "rotating" assemblies in which the radius is infinitely large, one can provide individual assemblies which move linearly in either different directions or at different velocities, as generally illustrated in Figures 11 and 15, discussed in more detail below.
  • FIGS 2, 2-1, and 3 show a first example of the above principles, in which the household appliance having a rotating head is a cleaning brush 1.
  • the power input is provided by a rotating shaft 2 or equivalent rotating shaft 151 driven by a motor (not shown).
  • a motor not shown.
  • any motor can be used, and that details of the motor form no part of the invention.
  • shaft 2 is supported by appropriate bearings in a housing 3, to which is affixed bearing members 4-7, bearing member 4 being preferably affixed to housing 3 by an additional sleeve 6'. Both shaft 2 and an outer bristle supporting member 8 are rotatable relative to bearing members 4-7.
  • the brush assembly of the counter-rotatable cleaning brush of this variation of the first embodiment of the invention includes an inner circular bristle 9 and an outer annular bristle assembly 10 arranged to rotate in opposite directions and supported, respectively, by cylindrical support member 11 and the above-mentioned support member 8.
  • Support member 11 is preferably directly affixed to and rotated by shaft 2, while the counter-rotation effect for support member 8 and the second bristle assembly 10 is provided by a planetary gear system made up of a drive gear 12 affixed to the motor shaft 2, a ring gear 13 affixed to support member 8, and at least one idler gear 14 rotatable about a pin 15 secured to the bearing members 4-6 so as to prevent the idler gears 14 from revolving around the drive gear 12.
  • a brush is provided in which the outside bristles rotate in a direction opposite that of the inside bristles, thus providing an improved brushing effect without the need for a second motor or additional main shaft, or for significant modifications of the existing motor, drive shaft, and housing structure (although the improved brushing effect could also be achieved even if a second motor and/or shaft are provided).
  • the only additions to the conventional structure which are required are a ring gear, idler gears, a drive gear on the shaft, and an additional support member for the outer bristle assembly.
  • the single ring and idler gear mechanism is replaced by a double ring gear mechanism made up of a first ring gear 150 driven by and secured to motor-driven shaft 151 to rotate therewith, at least one pinion 152, 153 rotatably connected to reversing brush module housing 154 by a pin 155,156 and bushing 157,158 and in engagement with first ring gear 150 to rotate in response to rotation of the first ring gear, and a second ring gear 159 rotatable relative to shaft 151 in a direction opposite the direction of rotation of the first ring gear 150 in response to rotation of the at least one pinion 155,156.
  • the inner and outer assemblies in this variation of the first embodiment rotate in opposite directions at the same speed, the cross cleaning effect is optimized. Further, balancing is easily achieved by appropriate selection of the contact areas of the respective assemblies, taking into account the coefficients of the assemblies if the materials of the bristles between the inner and outer bristles is different, while both balancing and cross-cleaning can be improved, in this and the other variations of the illustrated embodiment, by increasing the number of rotating assemblies, i.e., by using a larger number n of layers.
  • the inner brush head 160 is affixed to the first ring gear 150 by means of a locking screw 161, with the first ring gear and inner brush head forming a bearing surface 162 for permitting counter-rotation relative to the second ring gear 159.
  • the second ring gear is affixed to outer brush head 163 by, for example, location pins 164.
  • the inner brush head 160 rotates with shaft 151 and outer brush head 163 rotates in an opposite direction relative to the shaft to obtain a counter-rotation effect for the respective inner bristles 165 and outer bristles 165'.
  • Attachment of the counter-rotating brush assembly to the motor unit is achieved by a sleeve 166 having latch arms 167 arranged to be inserted into and engage a central opening in a main housing 168 that contains the motor and gear trains required to drive shaft 151, thereby securing the brush assembly to the main housing as the shaft 151 is inserted or snapped into a bushing provided in the first ring gear 150.
  • sleeve 166 extends to form a cover for the brush head, with the cover portion 166' including openings for receiving locating splines 169 for orienting the brush head module thus formed with the main housing 168, resulting in a particularly convenient modular design which permits the brush head assembly to be easily removed for replacement or cleaning, as illustrated in Figure 2-2.
  • the modular design illustrated in Figure 2-2 can be used with gear arrangements other than that shown in Figure 2-1, including the gear arrangement shown in Figure 2, as well as in other types of brushes employing the counter-rotation principles of the invention, and also in connection with the generalized form of the present invention in which there are n members and adjacent members rotate at different speeds and/or directions, as described above in connection with Figure 1.
  • Figures 2-3 and 2-4 show a variation of the design shown in Figures 2-1 and 2-2, in which the number of brush heads is increased from two to four.
  • the mechanism of this embodiment is made up of first ring gear 250 driven by and secured to motor-driven shaft 251 to rotate therewith, idle gears 252-254 mounted for rotation by means of pins 256 secured in bushings 257 in the brush module housing 258 and engaged with respective brush units 259-262 such that idle gears 252 are rotated by ring gear 250, causing brush unit 260 to rotate at the same angular speed in an opposite direction to the direction of rotation of the ring gear, the rotation of brush unit 260 causing rotation of idle gears 253 and counter-rotation of brush unit 261, the counter-rotation of brush unit 261 causing rotation of idle gears 254 and rotation of brush unit 262.
  • the first or inner brush unit 259 is directly connected to shaft 251 such that each adjacent brush unit rotates at the same angular
  • the inner brush unit 259 is affixed to ring gear 250 by means of a locking screw 264, with the inner brush unit including a bearing surface 265 for permitting relative rotation of the second brush unit 260, the second brush unit including a bearing surface 266 for the third brush unit 261, and the third brush unit including a bearing surface 267 for the fourth brush unit 262.
  • each of the brush units can be snap fit into the brush module housing 258.
  • Attachment of the brush module housing 258 to the motor unit may be achieved, in a manner similar to the embodiment of Figures 2-1 and 2-2, by a member 267 having latch arms 268 arranged to be inserted into and engage a central opening in a main housing 269 that contains the motor and gear trains required to drive shaft 251, thereby securing the brush assembly to the main housing as the shaft 251 is inserted or snapped into a bushing provided in the ring gear 250.
  • the respective "inner” and “outer” bristle support members 16,17 of a cleaning brush 18, which may otherwise correspond to the one shown in Figures 2 and 3, need not necessarily be concentrically arranged, but rather may be arranged in a three dimensional configuration to provide axially spaced but still coaxially rotatable bristle assemblies 19 and 20.
  • the gear arrangement of this example may be identical to that shown in Figures 2 and 3, with the only difference being that the bristle support members are extended in a cylindrical configuration, although other gear arrangements could of course also be used with this offset configuration, including the gear arrangement shown in Figure 2-1.
  • the cleaning brush is in the form of a toothbrush 21 having an outer bristle assembly 22 which rotates in a first direction and an inner bristle assembly 23 which rotates in a second direction. Because the toothbrush 21 must be perpendicular to the drive shaft 24, a different gear arrangement is used.
  • a bevel drive gear 25, or similar gear such as a crown gear, is connected to the drive shaft.
  • the motor (not shown) and drive shaft 24 may be of an identical construction to conventional rotary toothbrushes, including appropriate bearing supports 26 in a housing 32.
  • the bristle assemblies of the toothbrush are supported by concentric inner and outer support members 27 and 28, the outer support member 28 being connected directly to a second bevel gear 29 or similar gear such as a crown gear, and the inner support member 27 being connected via a second shaft 30 to a third bevel gear 33 or similar type of gear positioned such that both of gears 29 and 33 engage the drive gear 25 and rotate in response thereto to drive the inner and outer bristle supporting members 27 and 28 in opposite directions.
  • a third non-rotatable bristle assembly or ring 35 depending from a housing 38 is added to the first and second bristle assemblies 36 and 37 of an electric toothbrush 34.
  • the stationary outer ring has the advantage of providing a more gentle massaging effect for the gums and to reduce splashing from the inner bristles.
  • gear arrangement of Figure 5 is replaced by a drive gear 170 connected to shaft 171 and rotatable therewith, as shown in Figures 5-1 and 5-3, drive gear 170 in turn engaging a first ring gear 172 and a second gear 173, which as a result are driven by gear 170 to rotate in opposite directions.
  • first ring gear 172 is connected by means of, for example, a snap fitting 172A to an inner brush assembly 174 which thereby rotates in the direction of rotation of the first ring gear, and the second ring gear 173 is constructed to be integral with the outer brush assembly 175, thereby causing the bristles of the respective inner and outer brush assemblies to rotate in opposite directions to provide improved balance, counter-torque, and cross-cleaning effects.
  • the toothbrush body 176 will include appropriate bearing surfaces for the various moving components, as well as means for assembling the body and shaft to a motor unit.
  • Figure 7 shows an application in which the bristles of the various brush designs are replaced by polishing or buffing discs to obtain a hand-held polisher 39 of the type used to polish automobiles.
  • the structure of the transmission mechanism for driving the two oppositely rotating polishing heads using via a common motor and drive shaft may be the same as shown in Figures 2 and 4, although variations of the above will undoubtedly occur to those skilled in the art.
  • the illustrated car polisher includes a handle 40 in the housing 41, making it important to minimize the space taken up by the motor and transmission mechanism. Also shown is a power cord 42 for the motor.
  • members 43 and 44 correspond respectively to bearing members 4 and 7 shown in Figure 2, with the bristle assemblies 23 and 22 shown in Figure 2 being replace by polishing wheels or discs 45 and 46.
  • Figure 8 shows a variation of the polisher illustrated in Figure 7, in which the basic structure of the first embodiment of the invention is adapted for use as a floor polisher 51 having a pivotable handle 47, main housing 48, and respective counter-rotatable inner and outer polishing discs 49 and 50 .
  • the basic structure of the first embodiment of the invention is adapted for use as a floor polisher 51 having a pivotable handle 47, main housing 48, and respective counter-rotatable inner and outer polishing discs 49 and 50 .
  • details of this variation of the first preferred embodiment of the invention can be identical to those of the variation shown in Figure 7.
  • Figures 9 and 10 show further applications of the principles of the first embodiment of the invention.
  • Figure 9 shows a hand-held battery operated shoe brush or polisher 52 having oppositely rotating bristle or polishing heads 53 and 54
  • Figure 10 shows a hand-held battery operated massager 55 of the type including a plurality of massaging balls 56 mounted on oppositely rotating heads 57 and 58.
  • the respective housing assemblies 62, 63, and 64 of the respective devices shown in Figures 9 and 10, including battery compartment covers 65 and 66 , handle 67, and on-off switches or trigger controls 68 and 69 are conventional and therefore need not be further described herein.
  • Figure 11 shows the more general situation in which the linear movable members do not oscillate, but rather move continuously.
  • the linearly movable members may support bristles 74 of a brush, which may take the form of a shoe or cleaning brush having a housing 75 in which the mechanism of Figure 12 is mounted, as illustrated in Figure 13.
  • the linearly movable members may support the massaging balls 76 mounted in the housing 77 of a massager, as illustrated in Figure 14.
  • the mechanism illustrated in Figures 11-14 may also be applied to polishers, sanders, and similar household appliances or tools.
  • the invention can also take the form of a household appliance or personal grooming device in which the side-by-side tools or heads are caused to reciprocate or oscillate in order to obtain the advantages of improved balance and cleaning effect, as well to reduce the effort needed to manipulate the appliance since the reaction force caused by a tool moving in one direction will be countered by the force of a tool moving in the opposite direction to provide a linear analogue of the counter-torque effect.
  • the invention may be embodied by an arrangement 90 for converting the rotation of a shaft 91 into linear oscillations of a plurality of members 92, illustrated as carrying bristles 93 but which may also carry massage massaging balls, sponges, or the like, with each member being 180° out of phase in the path of movement relative to a neighbouring member.
  • the oscillations are achieved, for example, by a crankshaft 94 to which are pivotally attached a plurality of connecting rods 95, which in turn are pivotally connected to the tools or heads 92 which carry out the function of the apparatus.
  • crankshaft arrangement As was the case with the first embodiment of the invention, it should be appreciated by those skilled in the art that numerous other mechanical arrangements for converting rotational to linear reciprocating motion may be substituted for the illustrated crankshaft arrangement, and that the invention lies not in the use of a crankshaft per se, but in application to a cleaning or personal grooming device, as illustrated in Figures 16 and 17.
  • Figure 16 shows a cascade-type brush 96 which utilizes the mechanism 90 shown in Figure 15.
  • the linearly oscillations produced thereby have advantages over the counter-rotating brush in a number of applications.
  • the counter-rotating brush cannot be used as a hair brush, head massager, or head washing device of the type intended to simulate human fingers for use during shampooing because the hair will become entangled.
  • the linear oscillating or reciprocating brush with counter oscillations solves this problem.
  • the linearly reciprocating brush can be used as a shoe cleaning or polishing device which provides a cross-cleaning effect with minimal vibration due to the canceling moments of inertia.
  • the linear reciprocation principles of this embodiment can be applied to a massager 97, which is similar to the rotary massager shown in Figure 10 in that it includes a plurality of massaging balls 98 and results in a crossmassaging effect with minimal undesired vibration.
  • Figure 18 illustrates a variation of the counter-rotation illustrated in Figures 1-10, in which two heads 103 and 104 are provided, the principles of the invention of course being applicable to any desired number of heads
  • Figure 19 illustrates a variation of the mechanisms illustrated in Figures 1-10, in which dual shafts 105 and 106 are provided to drive the differentially rotating sections 107 and 108, the principles of the invention being applicable. to numerous different shaft and gearing combinations.
  • Figures 20, 20-1, 20-2, and 20-3 depict a fingernail cleaning device in which the two rotating heads 180 and 181 are arranged coaxially, each of the heads being in the form of a cylinder having radially inward facing bristles.
  • This embodiment solves a number of problems which prevent effective cleaning of fingernails by a device having only a single rotation direction. The problems result in part from the shape of a fingernail and in particular the presence of a recess on both sides of the fingernail where it is embedded into the skin.
  • the rotating heads 180 and 181 of this embodiment may be driven by a gear arrangement similar to that of Figure 2-1, but the shaft arrangement differs in this device in that a detachable coupling made up of engaging coupling elements 182 and 182' is included to permit the rotating head section to be detached from a main drive unit for cleaning.
  • Coupling element 182' is fixed to a main drive shaft 183 to rotate therewith, and is further coupled to the first ring gear 184 and to an intermediate shaft 185 by a locking nut 186.
  • Intermediate shaft 185 is in turn fixed to rotating head 180 via-separate inner cylinder 180A while the second ring gear 187 is fixed to an outer cylinder 188 which in turn is fixed to second rotating head 181, the second ring gear being driven to rotate in a direction opposite that of the first gear by pinions 189,190 engaged with both ring gears and rotatable about pins 191,192 supported by bushings 193,194 in support member 195, which is attached by locking screws 196 to outer casing 197.
  • casing 197 can be made separable from the main unit 198, for example by means of a twist off coupling 198', and both of the rotating heads 180 and 181 can be separately removed for cleaning or replacement by first detaching head 181 from cylinder 188 and then detaching head 180 from cylinder 180A.
  • the main unit 198 best illustrated in Figure 20-3, includes the motor, additional gearing (not shown), and an on/off switch 199.
  • Figures 21 and 22 are intended to illustrate the effect of eliminating twisting of brushes having relatively long bristles.
  • Figure 21 shows a single head brush in which the bristles twist as the head is rotated
  • Figure 23 shows a counter-rotating head device according to any of the above embodiments in which twisting is minimized due to the effect of the counter-rotation.
  • Figure 18 shows a variation of the counter-rotation mechanism illustrated in Figures 1-10, in which two heads are provided, the principles of the invention being applicable to any desired number of heads
  • Figure 19 illustrates a variation of the mechanisms illustrated in Figures 1-10, in which dual shafts 105 and 106 are provided to drive the differentially rotating sections 107 and 108, the principles of the invention being applicable to numerous different shaft and gearing combinations.
