Definitions
- the present invention relates to a shoe sole cleaner which comprises at least two parts: the machinery section and the essentially planar brush section.
- the purpose is to replace conventional boot-scrapers, grates and doormats by the apparatus of the present invention.
- a typical feature of the operation of the new shoe sole cleaner is that it does the cleaning automatically so that the user does not have to actively scrape his shoes to the aforementioned devices.
- the dust container of the apparatus is an unnecessary auxiliary device, which unreasonably increases the cost of the whole apparatus - although it cannot suck the litter and sand collected into the box placed under the brushes, but only the finely powdered dust.
- the aforementioned drawback is caused by the air leakages through the brush intervals, which effectively prevent the creation of sufficient suction.
- the Norwegian patent No. 96305 also introduces a shoe cleaning machine, where an electric motor rotates a brush belt. The belt cleans the shoes of anyone stepping on the apparatus. Under the apparatus there is arranged either a removable, drainable trough or a separate conveyor which carries the sand and litter away. It is apparent that this apparatus is, like the ones above, fitted into the floor construction and thus meant to be installed already at the building stage. Therefore this kind of apparatus is not suited for replacing an ordinary doormat as a later installation.
- shoe sole cleaner introduced in the US patent 3,228,052 is likewise meant to be installed at a recess arranged in the building already at the building stage. In this apparatus, too, the cleaning of shoe soles is carried out by aid of a rotating brush belt. Similar cleaning apparatuses are introduced for instance in the Swedish patent 48271 and in the US patent 4,014,060.
- the brushes move back and forth for example by means of a crank lever mechanism coupled to an electric motor.
- the apparatus is also designed for installation in a recess.
- figure 1 is a perspective illustration of a shoe sole cleaner of the invention
- figures 2a and 2b are partial longitudinal and transversal cross-sections of the apparatus of figure 1
- - figures 3a and 3b illustrate a preferred embodiment of the power transmission and gearing arrangements for the shoe sole cleaner of the invention, seen in partial cross-section from the side and the top

- figure 5 illustrates a shoe sole cleaner with a wide construction
- figure 6 illustrates a detail of the connecting joint between separate cleaners
- figure 7 illustrates a preferred embodiment of the mechanism for moving the brushes
- figure 8 is a perspective illustration of another shoe sole cleaner
- figure 9 is a schematical illustration of the structure and operation of the apparatus of figure 8
- figures 10a and 10b illustrate a preferred embodiment of a certain piece of machinery which is used in the cleaner of figure 8, seen in partial longitudinal and transversal cross-section
- figure 11 illustrates
- the shoe sole cleaner 1 of figure 1 is mainly composed of the machinery section 2 and of the brush section 3.
- the machinery section 2 is advantageously coupled to the electrical network by means of the wire 4.
- the dimensions of the apparatus are for instance as follows: length, in the longitudinal direction of the machinery section 2, about 800 mm, total width about 1000 mm, and the width of the brush section about 800 mm, so that the apparatus can be fitted into ordinary hallways.
- An cleaner designed particularly for use in private homes could respectively be of the size 500 x 600 x 800 mm.
- the brush section of the apparatus of the invention is advantageously low; its height h is for instance roughly 25-30 mm, so that the apparatus fits into the recesses meant for ordinary doormats for instance in shops and other such places. Similarly, in private homes the apparatus is placeable immediately adjacent to the treshold, so that the formation of any inconvenient platform is avoided.
- the machinery section 2 of the cleaner 1 comprises for example a gearing whereby the rotation speed of the electric motor is reduced to be suitable for the brushes 9.
- the electric motor rotates the axis 5, wherefrom the motion is transmitted to the axis 6 for instance by intermediation of a belt 7 or the like.
- the employed transmission members can also be ordinary cog-wheels, chains or a cogged belt. From the axis 6, the motion is further transmitted for example by aid of the belt 8 to the axes 10 of the brushes 9.
- These axes 10 can be interconnected either by intermediation of chains, belts or cog-wheels, but advantageously so that the rotation directions of adjacent brushes 9a, 9b (arrows in figure 2b) are opposite.
- the brush section 3 is formed of the brushes 9 and of the grill plates 11 fitted in between them, the said grill plates being the members that carry the weight of the user.
- a switch for switching the cleaner on and off can also advantageously be coupled to the grill plates 11. By aid of the switch, the apparatus is started while the grill plates 11 are pressed down, and respectively the operation is stopped when the grill plates rise up, for instance by aid of springs.
- FIGS 3a and 3b illustrate an advantageous embodiment for the brush and machinery sections of the invention.
- the brushes of the brush section are rotatable and they are arranged to rotate to opposite directions.
- the reference number 12 refers to the axis of the electric motor, which axis rotates the gear wheel 14 by means of the belt 13, and on the axis 15 of the said gear wheel 14 there is attached the belt wheel 17 of the belt 16.
- the machinery comprises the guiding wheel 18, which guides the belt 16 to move horizontally nearly at the same level as the brush rods 19.
- the machinery comprises, at the other end of the machinery section 2, another guiding wheel (not illustrated in the drawings), which guides the belt 16 to pass via the axes 19a of the brush rods.
- the brushes are made to rotate to opposite directions by arranging the belt to pass in turn under, over and in between the axes 19a.
- Another solution is to provide each brush rod with a separate belt wheel. in which case a thin belt, for instance a V-belt, can be employed.
- the first arrangement is, however, remarkably more economical as regards manufacturing costs.
- The-machinery itself is encased within the box 20, the structure whereof is seen in more detail in figure 3b.
- the axes 19a of the brush rods are attached with bearings to the perforated fillets 21, 24 or the like located on both sides of the box, which fillets are advantageously made of plastic.
- the end plate 22 of the box 20 prevents the axes 19a from moving in the axial direction.
- the end plate 25 is provided with holes for the axes 19a, through which holes the axes are pushed out to the extent that the brush rods 19b proper can be fastened thereto by means of the coupling sleeves 23.
- the brush section 3 itself is advantageously connectable to the machinery section 2 by means of fast couplings attached to the end plates 24 and 25.
- FIG 4 shows how the apparatuses can be attached to the floor by means of hinges 30.
- hinges two advantages are gained: thereby the cleaners are kept in place, and the cleaning of the area underneath the cleaners is easily carried out by lifting the cleaners to an upright position supported with the hinges. According to the drawing, it is possible to compile a large cleaner for instance of the size 2400 x 2000 mm, which is sufficient for even a large crowd of users.
- Figure 6 illustrates how the brush ' sections 3a, 3b of the cleaner are interconnected so that the power transmission from one brush section to another is successively carried out.
- the left-hand side brush section 3 ends to a side bar 26a, which serves, either in accordance with figure 2 as the bearing point of the end axis 27, or as the second bearing point of the connecting axis 28.
- the brush rod 29a of the brushes 9 is connected to the axis 27 or 28 provided with bearings, by aid of a connecting sleeve 23; 23a, 23b, which allows for axial motion.
- the connecting sleeve 23 may be a spring coil, a metal, rubber or plastic sleeve or a similar member.
- Figure 7 illustrates a preferred embodiment of the machinery section 2 of the cleaner of the invention, wherein the brushes are moved axially.
- the power unit such as an electric or hydraulic motor
- a crank lever mechanism by means of the power unit such as an electric or hydraulic motor, and by intermediation of for instance a crank lever mechanism, a longitudinal back and forth motion A for the cam bar 31.
- the brush rods 33 conforming to the cams 32 of the cam bar 31 thus assume an axial motion.
- the back and forth motion of the brush rods is provided for by the springs 34 arranged at the opposite ends of the said rods, which always return the rods, along the surface of the cam bar, back to the initial position.
- the cam bar of the machinery section is replaced by a bar extending over the length of the whole machinery section 2, which bar is affected by the wobblers * located on the axis of the electric motor so that the wobblers set the brush rods to a corresponding axial motion.
- the same springs which were introduced in the previous embodiment are also here suitable for returning both the brush rods and the shifting bar to the initial position.
- the motion of the brushes is particularly advantageous.
- the grooves provided in shoe soles are generally transversal, so that the motion in question cleans the grooves thoroughly and does not gather snow or the like only to the far end of the elongate groove.
- the length of the working impact required by this task i.e. the height of the cams 32 of the cam bar 31, may be even below 10 mm. Even 7 mm is sufficient - it has proved to clean the sole to a satisfactory degree provided that the brushes are stiff enough, and that the bristles are short.
- the bristles may be arranged in between two flat irons which are riveted or otherwise fastened to each other.
- the bristles may also be installed in a perforated pipe, or a bristle cloth may be glued on top of the pipe.
- the bristles may be arranged in between angle irons, which irons are then riveted or otherwise fastened to each other.
- the bristles may be arranged in between twisted metal wires (cf. bottle brushes or the like) .
- FIG 8 illustrates another different embodiment for the shoe sole cleaner 1 of the invention.
- This cleaner comprises the machinery section 2 and the brush section 3.
- the machinery section 2 is fastened to the wall. It contains an electric motor which is connected to the electric network by means of the wire 4.
- the electric motor runs the hydraulic power transmission machine, which in turn is coupled by pipes 35 to the brush section 3.
- the brush section 3 contains a piston and cylinder combination whereby the brush rods are made to move in a desired, circling back and forth motion, either in the axial direction or in a direction vertical to the axis.
- the brush section 3 is installed to a suitable place near the entrance door. At a suitable height. In between the brush section 3 and the entrance door, there is placed the photocell 41, by means of which the electric motor and the connected brush section 3 are switched to operation when somebody steps in through the door.
- the wobbler 38 located on the axis 37 of the electric motor moves the piston or pistons 39 located on the opposite sides of the wobbler and belonging to the hydraulic power transmission machine 40, so that the liquid in the pipes 35 flows, owing to the effect of the two pistons, in turn in opposite directions to the time of the rotating motor.
- the cylinders 42, wherein the pistons 39 moved by the wobbler 38 are located are fastened in a stationary fashion for instance to the housing of the machinery section and coupled, by intermediation of the pipes 35; 35a, 35b, to the third cylinder 43, one pipe 35a to one side of the piston 44, and the second pipe 35b to the other side of the same piston 44.
- the liquid moving back and forth to the time of the rotating motor makes the piston 44 of the third cylinder to move to the same rhythm.
- the impetus for the brush rods is obtained from the back and forth vibrating piston 44 by intermediation of the piston rods 45.
- the liquid can be conducted into the cylinder 43 also through the piston rods 45, in which case the piston rods 45 are permanently fastened to the brush section, and the cylinder 43 moves and the impetus for e rus ro s s obtained therefrom.
- a countervalve 46 which is connected to the tank 47, wherefrom fresh liquid is automatically fed into the machine via the countervalve 46 if a liquid deficit tends to arise in the pipes or in the cylinder.
- the piston 44 of the cylinder 43 serving as the vibrating member is not absolutely compact, in order to allow the liquid and the pressure to be balanced throughout the system. This minor leakage is not of essential importance in the operation or efficiency of the hydraulic power transmission machine, because the vibration frequency is so high - for instance 10 Hz - that the leakage has not time to affect the motion.
- the hydraulic power transmission machine 40 of the above described type has the advantage that the power unit, i.e. the machinery section 2 (the motor and the pistons moved by the wobblers) can be placed apart from the vibrating members proper, i.e. from the third piston and cylinder combination, even to a distance of several meters, and the vibrating member itself fits into a small, essentially low space in connection with the brush section 3.
- the power unit i.e. the machinery section 2 (the motor and the pistons moved by the wobblers) can be placed apart from the vibrating members proper, i.e. from the third piston and cylinder combination, even to a distance of several meters, and the vibrating member itself fits into a small, essentially low space in connection with the brush section 3.
- FIGS 10a and 10b are detailed illustrations of a preferred embodiment of the machinery section 2 of the shoe sole cleaner of the invention, as represented in figure 8.
- the electric motor 36 is attached to the oil chamber 49 by aid of the flange 48.
- the axis 37 of the electric motor 36 is provided with the first cog-wheel 50, and the auxiliary axis 51, which is journalled in between the walls of the oil chamber 49 with bearings 52, 53, is provided with the second cog-wheel 54.
- the cog-wheels 50, 54 the rotating speed of the motor is adapted to be suitable for the hydraulic power transmission machine.
- the employed wobbler is a round disc 55, which is eccentrically fastened onto the auxiliary axis 51. It may also be elliptical in shape.
- the first and second cylinder 42a and 42b whereto the pistons 39a, 39b are respectively fastened.
- the piston ends are arranged to comform to the circumference of the disc 55.
- the cylinder chambers of the cylinders 42a, 42b are connected to the pipes 35a, 35b respectively, and the pipes are further connected to the brush section 3.
- One of the pipes 35a, 35b is advantageously connected both to the feed valve 56 and to the bottom of the oil chamber 49.
- the feed valve 56 the oil pipes 35a, 35b and the hydraulic power transmission system are filled with oil.
- the bottom service link 57 any oil deficit in the system is rapidly made up for by the oil from the oil chamber.
- the feed valve 56 and the bottom service link 57 comprise the first connecting T-piece 58, the first back ⁇ pressure valve 59, the second connecting T-piece 60, the second back-pressure valve 61 and the service pipe 62 connected the the bottom of the oil chamber 49.
- the pump 64 can be removed by winding, and replaced, similarly by winding, by an oil feed pipe from a suitable external tank.
- the system may also be filled from the oil chamber 49 by aid of the piston pump 64, and the oil chamber in turn through a suitable inlet or valve.
- the pipes 35; 35a, 35b are connected to the brush section 3 of the cleaner 1, as is apparent from figure 8.
- the brush section 3 is provided with the third cylinder 43 and the third piston 44 of the said cylinder, as is schematically illustrated in figure 9.
- Figure 11 illustrates the point B of the brush section 3 of figure 8.
- the piston 44 and the connected piston rod 45 are in a stationary fashion attached to the housing of the brush section 3.
- the pipes 35a, 35b are connected to the channels 65a, 65b of the piston rod 45 respectively.
- the first channel 65a opens into the cylinder space located on the left-hand side of the piston 44, and the second channel 65b opens to the cylinder space located on the right-hand side of the piston 44.
- the moving cylinder 43 is permanently fastened to the transmission shaft 66, having the same width as the brush section 3, and the brush rods 10 and the brushes 9 fastened thereto are moved by aid of the said transmission shaft 66.
- the transmission shaft 66 is connected to the brush rods 10 for instance in the following fashion.
- the brush rods 10 are connected, by aid of the connecting sleeves 23, to the adapter pieces 67. These are journalled to the transversal support bar 68 of the brush section 3.
- the end of each adapter piece 67 is advantageously provided with a flange or with an extension, where a pin 70 or similar bracket is placed eccentrically.
- the pin 70 is advantageous y prov e w a sensitive rotating roller 71 or bearing, or it can be provided with a suitable sliding surface.
- the pin 70 with roller 71 is fitted to move along the vertical groove 72 or the like of the transmission shaft 66.
- the vibrating back and forth motion of the .transmission shaft 66 may be roughly between 5-10 mm, whereby the brushes 9 and the brush rods 10 are wound 45-90° around their axes.
- the brush rods 10 are fitted within the sleeves 73, which are fastened to the end piece 74. Inside the sleeves 73 there are also provided springs 75, which press the brush rods 10 and the adapter pieces 67 against the transmission shaft 66 so that the pins 70 are kept in place in the grooves 72 of the transmission shaft 66. If it is desired that the brush section 3 should be extended by another brush section, then for instance the embodiment of figure 6 is applied instead of the sleeve 73.
- the apparatus of the invention has many preferred embodiments, and below we shall have a closer look at a few more of these.
- the apparatuses form a kind of a model series, so that several similar or nearly similar apparatuses can be compiled into a unit larger than one on the basis of the module principle.
- all modules are similar except for- the fact that, only one module is provided with an electric wire, whereas the rest are connected to the net via module connectors. Consequently, in principle two different kinds of apparatuses are needed in this embodiment, but it does not by any means complicate the manufacturing of the appliances. Electric couplings are in any case made completely manually by professionals.
- the arrangement of figure 5 is formed of two different types of elements, but here the right-hand element, i.e. the brush section only, corresponds to the brush section of the left-hand element, so that the actual differences in the two elements are the side bars which are as such replaceable members.
- the module principle in the embodiments of the present ivention is carried as far as possible without weakening the practicability of the product.
- Another advantage of the apparatus of the present invention is that it is easily maintained and cleaned.
- the brush rods are easily removed and replaced by first removing the connecting sleeves 23 by drawing them aside with respect to the connecting joint.
- the joint itself is advantageously made for instance so that the end of one rod is provided with a slot, and the end of the other rod is provided with a corresponding bracket.
- the cleaning of the apparatus i.e. the removal of the litter and sand gathered under the cleaner, is carried out either by lifting the apparatus to an upright position supported with hinges, or so that under the apparatus there is provided a separate low drawer, where the sand etc. is collected.
- the machinery part goes out of order it can advantageously be removed and replaced without having to replace the whole cleaner.
- the cleaner of the invention has all the advantages of the prior art devices, and in addition to this, there are provided a number of previously unknown improvements which considerably help in the installation and use of the apparatus, so that the apparatus compiled of similar elements can be used both in private homes and in small and large public facilities.
- the module construction of the invention allows for large production series and consequently a low purchase price, wherefore the cost of the apparatus is quickly redeemed in saved labour and reduced floor cleaning expenses.
- the machinery section 2 can be replaced by a low connecting member, having the same thickness as the brush section, and by a machinery section connected only to this connecting member.
- the connecting member may be an elongate U-pipe provided with a removable lid. Therein there is fitted a cam or cog bar, wire rope or the like, whereby the power is transmitted from a suitable motor to the cleaning brushes.
- the employed actuator for the machinery section can, instead of the electric motor or in addition to it, be an actuator operated with hydraulic pressure, as is suggested above. Moreover, some other type of motor or hydraulic machine can also be employed.
