- FIG. 6 is a cross-sectional View of a portable cord reel employed in my invention.
- FIG. 1 the mobile cleaning unit of my invention is shown as it is being readied for use.
- the reference number 20 designates the mobile cleaning unit generally.
- the cleaning unit 2G is comprised of a platform 21 which is supported on four wheels 22.
- a storage chamber 23 is mounted on the platform 21 .
- the storage chamber 23 is provided with shelves 25 on which there may be stored clean towels, linens, etc.
- a shallow bin 26 which may be used for the storage of containers of detergents, polish, toilet paper, cleaning tissues and other such things as are used in hotels or the like.
- a handle 27 Connected to the storage chamber 23 near the top thereof is a handle 27 and supported from this handle is a sack 28 in which soiled linen, etc. may be collected. Also connected to one side of the chamber 23 is a storage rack 29 which, as indicated in FIGS. l and 2, may be used for storing a suction hose or sections of a hollow wand shown in dotted lines.
- the vacuum cleaner tank unit 24 includes therein an apertured arrangement 31 within which there is situated a dust bag 32 which may be of the disposable type.
- a motor-fan unit designated generally by the reference number 33 which is comprised of an electric motor 34 driving a centrifugal fan 3S.
- the motor-fan unit 33 is mounted within the tank unit 24 in a suitable annular vibration damping mounting 36 which is welded or otherwise secured to the inner wall surface of the tank unit.
- a spring motor assembly designated generally by the reference number 37 As shown in FIG. 4 the spring motor assembly 37 is comprised of four spiral springs 38, each of which is Wound on a Separate storage drum 39.
- springs 38 are constant force springs; for example, Negator@ springs.
- a spring of this type tends to run to a drum of smaller diameter from one of larger diameter. Inasmuch as the larger drum is xed, the springs tend to rotate the plate 42 in the direction of the arrow A in order to unwind from the drum 40 and wind up on the smaller drums 39. This of course tends to rotate the entire tank unit 24 about the fixed shaft 41, thus Iwinding up the hose. Unwinding the hose rotates the unit 24 and plate 42 in the opposite direction, which causes the springs 38 to unwind from the drums 39 and wind up on the larger drum 40.
- Plate 42 which is welded or otherwise fastened to the inner wall of tank unit 24, includes a ball bearing unit 43 on which the tank unit and plate 42 rotate about the vertical xed shaft 41.
- the plate 42 is provided with a number of openings 44 for the passage of air which is exhausted from the fan unit 35, the air ultimately passing out of the tank unit 24 through the openings 45 near the bottom thereof.
- At the lower end of the tank unit 24 there is another disc-like plate member 46 having at the center thereof an annular bearing 47 about which the tank unit may rotate on vthe shaft 41. Also profvided, below the plate 46, is a thrust bearing assembly 48.
- the upper end of the tank unit 24 is provided with a removable cover 49 which has in the center thereof a short conduit 50 which is intended to enter a suitable opening provided in a cardboard end plate 51 of the dust bag 32.
- This winding guide assembly 52 is comprised of an elongated worm 53 which has a helical thread running therearound and a winding spool 54 which moves upwardly and downwardly along the worm 53 as the spool 54 is rotated by the hose running against it to guide the winding or unwinding of the suction hose 55.
- the pitch of the thread is such that the rotation imparted to spool 54 by the movement of a length of hose, equal to the circumference on the unit 24, causes the spool to advance along the Worm a distance equal to the diameter of the hose.
- Reference character 58 designates generally a portable cordwinder. This includes a base member 60* to which is secured a pair of brackets 62. Pivotally mounted on the brackets is a handle 64 which may be provided with retainers 66 for holding a suction cleaning tool, such as the floor brush 68.
- a cordwinder housing 70 which includes a central tubular portion 72 detiming a passage through the cordwinder.
- a reel 74 Rotatably mounted on the exterior of tubular member 72 is a reel 74 on which may be Wound an electric cord 76.
- One end of the cord is secured to the reel and electrically connected to a pair of slip rings 78, while the other end of the cord extends out of the housing and is provided with a male plug (FIG. l).
- Brushes 82 (FIG. 6) cooperate with the slip rings 78 and are connected by means of conductors 84 with receptacles 86 and I88 accessible from the exterior of the housing 70 at opposite ends thereof.
- An electric switch is mounted on the upper part of the housing Where it may be easily operated, and is connected in the circuit between the brushes 82 and both of the receptacles.
- a Negator or like type spring 92 is carried by a storage drum 94 rotatably mounted on a pin 96 carried by the housing 70. The other end of the spring is secured to the hub portion of the reel 74 and is arranged to be wound thereon by the rotation of the reel caused by unwinding of the electric cord.
- the diameter of the hub portion of the reel is greater than that of the drum 94 and as explained in connection with the spring motor 37, it is characteristic of this type of spring that it will tend to run from a drum of larger diameter to ⁇ one of smaller diameter, and in doing so it tends to rotate the reel 74 in a direction for winding the cord 76 thereon.
- a suitable latch mechanism (not shown) is preferably provided for restraining rotation of the reel 74 by the spring 92 when it is not desired to rewind the cord.
- the ends of the tubular member 72 are provided with suitable means, such as the annular lip 98 for receiving the latches 100 of a conventional push connector 102 secured to the end of each hose 55 and 59.
- the cordwinder has sufficient weight so that when placed on a supporting surface, such as a floor, it offers enough frictional resistance to movement over the surface to prevent the spring motor 37 from retracting the hose 55. This does away with the necessity of providing latches or the like for preventing rotation of unit 24 and consequently as soon as the operator picks the cordwinder o the floor and Walks to-ward the cart 20, the spring motor will immediately start to turn the unit 24 to rewind the hose therearound.
- Each hose is provided with current carrying conductors which preferably are built into the body of the hose and are connected to pigtails at each end.
- one end of the hose 59 is connected to the hollow passage through the cordwinder, while the other end may be connected to a suitable cleaning tool.
- this consists of a known nozzle 104 having a rotary brush 105 therein driven by an electric motor 107.
- the hose 59 is provided with electric conductors (not shown) therein which are connected at each end to pigtails 106 and 108 (FIG. l).
- Pigtail 106 is provided with a plug which may be received in the receptacle 86, while pigtail 108 is provided with a receptacle 110 adapted to receive a plug on the end of a cord 112 which leads to the motor 10-7 in the nozzle 104.
- hose 55- is provided with current carrying conductors having pigtails 114 and 116.
- Pigtail 114 is provided with a plug which may be received in the receptacle v88 (FIG. 6), while pigtail 116 enters cylinder 24 and is connected to supply current to the vacuum cleaner motor 34.
- the parts When not in use the parts may be stored on the cart 20 in the manner indicated in dotted lines in FIG. 1.
- the hose 59 may be disconnected from the cordwinder 58 and from the wands 118 and 120 of the nozzle 104 and the hose and Wands supported in the bracket 29.
- the hose 55 is disconnected from the cordwinder and wound around the cylinder 24.
- the cordwinder itself may be placed in any convenient location on the cart 20, such as on the platform 21 underneath the sack 28.
- Brackets 124 (-FIG. 1) may be provided on the side of the storage chamber 23 for holding the nozzle 104.
- the cart with all of the parts carried thereby may be moved along a hotel corridor or the wa'lk in front of motel units and stopped outside the door of a guest room.
- the operator merely removes the cordwinder from the cart, attaches the end of hose 55 thereto and carries the cordwinder into the room, the hose 55 automatically unreeling from the cylinder 24.
- the cordwinder When the cordwinder is placed on the oor, it will hold the hose against the tendency of the spring motor 37 to rewind it, as previously described.
- the hose 59 may be assembled to the wands 118 and 120 and the nozzle 104 connected to the latter.
- the opposite end of the hose 59 may then be connected to the cordwinder 70 and the plugs on the pigtails 106 and 114 connected to the receptacles 86 and 88, respectively.
- the cord 76 may then be withdrawn from the cordwinder housing 70 a'nd the plug- 80 inserted in any convenient receptacle in the room which is to be cleaned.
