The disclosure relates to vacuum devices and more particularly pertains to a new vacuum device for automatically vacuuming stairs.
An embodiment of the disclosure meets the needs presented above by generally comprising a pair of vacuum units coupled together by a connector. Each vacuum unit comprises a vacuum housing having a slot extending through a bottom surface of the vacuum housing. A plurality of side rollers is coupled to the vacuum housing for moving the vacuum housing in a first direction. A plurality of forward rollers is coupled to the vacuum housing for moving the vacuum housing in a second direction transverse to the first direction. A suction device is coupled to and positioned in the vacuum housing such that the suction device provides suction through the slot in the vacuum housing. The connector couples the vacuum units together in spaced relationship wherein the vacuum units move in tandem to vacuum the adjacent stair surfaces simultaneously.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
Each vacuum unit 12 has a slot 26 extending through the bottom surface 18 of the vacuum housing 14. A plurality of side rollers 28 is coupled to the vacuum housing 14 on the bottom surface 18. The side rollers 28 are configured for moving the vacuum housing 14 in a first direction which is transverse relative to the connectors 22 extending between the vacuum housings 14. A plurality of side motors 34 may be provided for each vacuum unit 12. Each side motor 34 is operationally coupled to an associated one of the side rollers 28 and may be reversible to provide lateral movement of the device 10 in opposite directions. A plurality of forward rollers 30 is also coupled to the vacuum housing 14 on the bottom surface 18. The forward rollers 30 are configured for moving the vacuum housing 14 in a second direction transverse to the first direction. A plurality of forward motors 32 is provided with each forward motor 32 being operationally coupled to an associated one of the forward rollers 30. The side rollers 28 may be positioned adjacent to a distal edge 58 of the vacuum housing 14 relative to the connectors 22. Each of the forward rollers 30 may be positioned adjacent to a proximal edge 60 of the vacuum housing 14 relative to the connector 22.
In each vacuum unit 12, a suction device 36 is coupled to and positioned in the vacuum housing 14 such that the suction device 36 provides suction through the slot 26 in the vacuum housing 14. A bag compartment 38 is positioned in an interior space 40 of the vacuum housing 14. A vent aperture 42 may extend through the vacuum housing 14 adjacent to the bag compartment 38. A vent filter 44 may be positioned adjacent to and covering the vent aperture 42 if desired. A suction filter 46 may also be coupled to the suction device 36. A beater bar 48 may be coupled to the vacuum housing 14 in a conventional manner such that the beater bar 48 is positioned in and extends along the slot 26. Each of a pair of side sensors 50 is coupled to an associated side section 52 of the perimeter wall 20 of the vacuum housing 14 of each vacuum unit 12. The side sensors 50 are operationally coupled to the side motors 34 to selectively reverse direction of the side motors 34 or stop engagement of the side motors 34 and initiate engagement of the forward motors 32 according to a pre-programmed pattern to promote movement of the device 10 down a stairway.
Each vacuum unit 12 has a battery compartment 54 and a battery 56. The battery 56 is electrically coupled to each side motor 34, each forward motor 32, and the suction device 36 of the vacuum unit 12. Each vacuum unit 12 may also have a switch 66 electrically coupled to the side motors 34, forward motors 32, suction device 46, sensor 50, and battery 56. The switch 66 is positioned on the perimeter wall 20 of the vacuum unit 12. The vacuum units 12 may be constructed to be structural equivalents to reduce production costs.
Each vacuum unit 12 may further include a processor 62 coupled to and positioned in the vacuum housing 14. The processor 62 is operationally coupled to the forward motors 32 and the side motors 34. A receiver 64 is coupled to and positioned in the vacuum housing 14. The receiver 64 is communicatively coupled to the processor 62. A remote control unit 66 may be provided having a transmitter 68. The transmitter 68 selectively transmits control signals 70 to the receiver 64 of each vacuum unit 12. A remote battery 72 may be coupled to and positioned in the remote control unit 66 in a battery compartment 74. The remote battery 72 is electrically coupled to the transmitter 68. A directional control 76 such as a joystick or the like is coupled to the remote control unit 66. The directional control 76 is communicatively coupled to the transmitter 68 wherein the transmitter 68 transmits the control signals 70 to the receiver 66 of each vacuum unit 12. Thus, the vacuum units 12 may be moved by manipulation of the directional control 76. Additional operations of the vacuum units 12 may be programmed into the remote control unit 66 using a remote processor 78 communicatively coupled to the transmitter 68. A power switch 80 may also be provided on the remote control unit 66 and operationally coupled to the remote processor 78. The power switch 80 may control both the remote control unit 66 and each vacuum unit 12.
In use, the device 10 is positioned at the top of a stairway. The device 10 moves laterally at least once across the uppermost stair driven by the side motors 34 actuating the side rollers 38. The forward rollers 30 are engaged by the forward motors 32 moving the device 10 to the next step on the stairway. The process continues automatically until the device 10 reaches the bottom step of the stairway.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure.
