DETAILED DESCRIPTION

(36) The invention relates generally to apparatuses and methods for cleaning. More specifically, the invention is an apparatus and method for cleaning that utilizes vacuum technology (collectively the apparatus).

(37) The apparatus can be implemented in wide variety of different configurations. In accordance with the provisions of the patent statutes, the principles and modes of operation of this invention have been explained and illustrated in preferred embodiments. However, it must be understood that this invention may be practiced otherwise than is specifically explained and illustrated without departing from its spirit or scope. For example, the apparatus can be implemented in a wide range of difference shapes and sizes, utilizing a wide range of different components. In many embodiments, the apparatus will be in the shape of a cube or a rectangular block, but other shapes are possible. The apparatus is readily scalable, and can be implemented in a modular manner. The apparatus can also be implemented in a fully mobile and portable configuration, as well as permanently embedded into a particular location.

(38) The apparatus can be adapted in a variety of alternative embodiments to better address specific operating requirements in specific operating contexts.

I. OVERVIEW

(39) FIGS. 1a-6r collectively illustrate (1) different examples of a cleaning apparatuses 100 that utilizes vacuum technology and (2) different components and component configurations that can be utilized in such apparatuses 100. The apparatus can include a variety of different components and component configurations. FIG. 1a is a perspective diagram illustrating an example of an embodiment of the apparatus 100 that is fully assembled. FIG. 1b is top view illustration of the apparatus 100 illustrated in FIG. 1a. In FIG. 1b, the operating environment of the apparatus 100 is also displayed. The apparatus 100 is embedded within a floor 99 instead of being place on the floor 99.

(40) A. Vacuum Cleaner

(41) The apparatus 100 can be used in conjunction with a wide variety of different vacuum cleaners. The requirements for suction power will necessarily be impacted by the size and intended context of the apparatus 100.

(42) As illustrated in FIGS. 1a and 1b, the apparatus 100 can include a vacuum adapter 108 (or simply an adapter 108). The suction of the vacuum cleaner operates to the apparatus 100 through the adapter 108. The purpose of the adapter 108 to connect the apparatus 100 to a vacuum cleaner (or some similar device that provides for generating suction force) that is otherwise separate and distinct from the apparatus 100. Although the marketplace can provide a wide range of product options for vacuum cleaners, there are a relatively narrow range of connection geometries that are typically used in the vacuum cleaner industry. Moreover the adaptor 108 can utilize a variety of extensions or plugs to facilitate compatibility with a wide range of different vacuum cleaner configurations.

(43) In most embodiments, it is advantageous to provide vacuum functionality to the apparatus 100 through the adapter 108 that is capable of being connected to various different vacuum devices rather than permanently building in the vacuum cleaner device into the apparatus 100 (or vice versa). A modular approach to the apparatus 100 that allows different components to be moved around can provide beneficial flexibility. An apparatus 100 permanently attached with an embedded vacuum cleaner is thus less desirable in most circumstances.

(44) B. Core Functionality

(45) The apparatus 100 uses vacuum technology, i.e. suction power, to facilitate the function of cleaning. The original inspiration behind the design of the apparatus 100 is the use of vacuum technology to clean shoes and feet, but at least some embodiments of the apparatus 100 can also be used outside of those contexts.

(46) 1. Loading the Apparatus

(47) Use of the apparatus 100 involves loading the apparatus 100, i.e. placing a mass on the top surface of the apparatus 100. As illustrated in FIG. 1a, the apparatus 100 has a top plate 104 with a variety of protrusions 106 sticking up through the top plate 104. FIG. 2a provides a close up top view of a protrusion component 106 in the shape of a hemisphere protruding upwards through a circular opening 110 in the top plate 104. Loading the apparatus 100 involves placing the load on one or more protrusions 106, placing downward force on one or more protrusions 106. For example, a human being wearing shoes steps onto the top plate 104 of the apparatus 100, stepping on some of the protrusions 106, resulting in the application of downward force on those protrusions 106.

(48) 2. Compression of the Tension Component

(49) As illustrated in the block diagram of FIG. 2d, a protrusion component 106 is supported by a tension component 112, which can also be referred to as a compression component 112. The tension component 112 serves to allow the vertical motion of protrusion component 106 while at the same time acting to resist the magnitude of such motion. In many embodiments, the tension component 112 is some type of spring or an assembly that includes one or more springs.

(50) The tension component 112 permits but also impedes the downward movement of the protrusion component 106. The result of that slight downward motion is to open a slight gap in the top surface of the apparatus 100.

(51) 3. Gap to Facilitate Cleaning

(52) In stepping on the apparatus 100, a slight gap is opened on the top surface of the apparatus 100 to permit sufficient air flow to facilitate cleaning. If the gap is too small, there is insufficient throughput for the debris being cleaned. If the gap is too large, then the suction power of the vacuum is negated, negatively impacting the ability of the apparatus 100 to perform the cleaning function of the apparatus 100.

(53) FIG. 2c illustrates an example of a protrusion component 106 in a fully unloaded state. The protrusion component 106 fits snuggly in the opening 110 in the top plate 104. In contrast, FIG. 2b illustrates the same components when the protrusion component 106 is loaded. As is illustrated in FIG. 2b, there is a small gap between the protrusion component 106 and the top plate 104 that does not exist in FIG. 2c. That gap must be the appropriate size to facilitate the throughput of debris while still maintaining near-vacuum conditions within the apparatus 100 itself.

(54) Both FIGS. 2b and 2c reveal that it can be desirable to have a tapered opening 110 in the top plate 104. The opening 110 is wider at the bottom of the top plate 104 than it is in the top of the top plate 104.

(55) C. Wet Vacuum and Dry Vacuum Embodiments

(56) The apparatus 100 can be implemented to utilize wet vacuum technology in conjunction with the application of water to perform the cleaning function of the apparatus 100. The apparatus 100 can also be implemented to utilize dry vacuum technology without the use of water to perform the cleaning function of the apparatus 100.

(57) D. Modular and Non-Modular Embodiments

(58) The apparatus 100 can be implemented in a modular manner that allows the apparatus 100 to connect with other apparatuses 100 to provide a wider area of functionality. FIGS. 6b and 6m illustrate how multiple apparatuses 100 can function as a single unit in a highly modular approach.

(59) As illustrated in FIGS. 1a and 1b, the apparatus 100 can also be implemented as a single stand-alone embodiment.

(60) E. Portable and Embedded Embodiments

(61) The apparatus 100 can be embodied in a highly portable device that consumers can take with them when they travel. The apparatus 100 can also be embodied in less mobile embodiments that can even involve embedding the apparatus 100 into specific locations as other types of fixtures are incorporated into living and office space.

(62) F. Materials

(63) The various components of the apparatus 100 can be comprised of a wide variety of different materials. In order to support the weight of human beings, many components such as the frame 102, top plate 104, and bottom plate 114 will often be comprised of a metal, such as aluminum. Other items such as the adapter 108 or protrusion components 106 can be comprised of plastic.

II. INTRODUCTION OF ELEMENTS AND DEFINITIONS

(64) FIG. 1a is a perspective diagram illustrating an example of an apparatus 100. FIG. 1b is a plan view diagram illustrating a top view of an apparatus 100 illustrated in FIG. 1a. In the example of the apparatus 100 illustrated in FIG. 1b, the apparatus 100 is embedded in a floor 99.

(65) A. Frame

(66) A frame 102 of the apparatus 100 can serve a variety of purposes for the proper functioning of the apparatus 100. The frame 102 can help implement the applicable vacuum-like conditions between a bottom plate 114 and a top plate 104 to support the functioning of the apparatus 100. The frame 102 can also serve to keep various components of the apparatus 100 in the appropriate and desired positions.

(67) Examples of frames 102 are illustrated in FIGS. 1a, 1b, and 3a. A frame 102 can be comprised of various L-brackets 127 (see FIGS. 6d and 6j) and/or U-brackets 126 (see FIG. 6a)

(68) The frame 102 is typically rectangular in shape, although it can be implemented in different shapes. The frame 102 also assists in sustaining near vacuum conditions between the top plate 104 and the bottom plate 114. The frame 102 can be made of a wide variety of different materials. In most embodiments of the apparatus 100, the frame 102 is stationary throughout the use of the apparatus 100. A frame height 116 (see FIG. 3a) exceeds a maximum top plate vertical position 120 (see FIG. 3c) as well as the minimum top plate vertical position 118 (see FIG. 3b).

(69) B. Bottom Plate

(70) FIG. 1a illustrates an example of a bottom plate 114. The bottom plate 114 is not visible in FIG. 1b because FIG. 1b is a top view of the apparatus 100.

(71) Examples of a bottom plate 114 are also illustrated in FIGS. 3a, 3b, 3c, 3d, 4a, 4b, 4c, 6a, 6b, 6n, and 6o. The bottom plate 114 forms the base of the apparatus 100. In conjunction with the top plate 104 and the frame 102, the bottom plate 114 helps sustain near vacuum conditions within the apparatus 100. In most embodiments of the apparatus 100, the bottom plate 114 is stationary through the use of the apparatus 100. In many embodiments of the apparatus 100, the bottom plate 114 is comprised of aluminum, although a wide variety of different materials and component configurations can be used.

(72) C. Top Plate

(73) Both FIGS. 1a and 1b illustrate examples of a top plate 104. Top plates 104 are also at least partially illustrated in FIGS. 2a, 2b, 2c, 3a, 3b, 3c, 3d, 4a, 4b, 4c, 6c, 6j, 6k, 6m, 6n, and 6o.

(74) In conjunction with the bottom plate 114 and the frame 102, the top plate 104 helps sustain near vacuum conditions within the apparatus 100. In many embodiments, the position of the top plate 104 is fixed, with one or more aspects of the tension-protrusion assembly moving in response to the load of the apparatus 100. In a preferred embodiment, the position of the top plate 104 is fixed regardless of whether the apparatus 100 is loaded.

(75) In other embodiments, the top plate 104 may be supported by a tension-protrusion assembly and move when the load on the apparatus 100 is changed. In such embodiments, the position of the top plate 104 will vary from a maximum vertical position 120 with respect to the bottom plate 114, and a minimum vertical position 118.

(76) Something in the apparatus 100 will move when the apparatus 100 is loaded, so there will relative positions in the apparatus 100 that will be different when the apparatus 100 is loaded from when the apparatus 100 is not loaded.

(77) In embodiments where the top plate 104 does not move, the distance between the top surface of the top plate 104 and the top of the protrusion component 106 changes when the magnitude of the load on the apparatus 100 changes.

(78) In embodiments where the top plate 104 does move, the distance between the top surface of the top plate 104 and the bottom surface of the bottom plate 114 changes when the magnitude of the load on the apparatus 100 changes.

(79) D. Openings/Holes in the Top Plate

(80) One important attribute of the top plate 104 are the openings 110 in the top plate 104 that provide for the positioning of a protrusion component 106 upward through the top plate 104.

(81) Examples of openings 110 are disclosed in FIGS. 1c-1e and 1 g-1i. A number of openings 110 in the top plate 104 provide for maintaining a balance between (a) the absence of air and water flow between the area above the top plate 104 and the area below the top plate 104; and (b) inadequate vacuum conditions for the effective cleaning of a connected vacuum cleaner. In a preferred embodiment, the openings 110 will be circular or some other type of elliptical shape, although alternative shapes are possible. The geometry of the openings 110 should be designed with the geometry of an applicable protrusion component 106.

(82) E. Tension-Protrusion Assembly

(83) As discussed above, the core functionality of the apparatus 100 involves the loading of a tension-protrusion assembly 133 as illustrated by the block diagram in FIG. 2d, as well as in less abstract figures such as FIGS. 4a, 4b, 4c, 6f, 6i, 6l, 6n, and 6o.

(84) The apparatus 100 can utilize a wide variety of different tension-protrusion assemblies 13 to facilitate the proper vertical motion of the top plate 104 in response to the loading of the apparatus 100 (putting mass on the apparatus 100) and the unloading of the apparatus 100 (removing mass from the apparatus 100).

(85) The tension-protrusion assembly can utilize a wide variety of different component parts, subassemblies, and configurations. Each tension-protrusion assembly will typically include a tension component 112 and a protrusion component 106.

(86) 1. Protrusion Component

(87) Examples of protrusion components 106 are illustrated in FIGS. 1a, 1b, 1c, 1d, and 1e. In many embodiments of the apparatus 100, the protrusion component 106 will be positioned on top of the tension component 112. A protrusion component 106 is the component in conjunction with the openings 110 that creates the geometry for enabling the proper air and water flow in the apparatus 100. In many embodiments, the protrusion component is a half-sphere. Other geometric shapes can also be used.

(88) Many embodiments of the protrusion components 106 will be hollow hemispheres 132 comprised of polyethylene and filled with silicon.

(89) 2. Tension Component

(90) Examples of tension components 112 are illustrated in FIGS. 1f-1i. A wide variety of components are capable of serving as a tension component 112, and thus a tension component 112 is illustrated by the black box in FIGS. 1f-1i. Common examples of tension components 112 are springs, but any device capable of contracting upon the loading of the apparatus 100, and then expanding back upon the unloading of the apparatus 100 can potentially serve as a tension component 112 for the apparatus 100.

(91) In many embodiments, flat springs 134 coupled into pairs will be used to collectedly support four hemispheres 132 comprised of polyethylene and at least partially filled with silicon.

(92) F. Mat

(93) FIG. 3d illustrates an example of a mat 121 sitting on top of the top plate 104. A mat 121 is an optional component of the apparatus 100. In many embodiments, the mat 121 can be removed from the apparatus 100 by the user/owner of the apparatus 100. The mat 121 serves the function of allowing the user to more easily remove excess debris from their feet, shoes, or other surface.

III. LOADING/UNLOADING OF THE TENSION-PROTRUSION ASSEMBLY

(94) As discussed above, the tension-protrusion assembly 133 of the apparatus 100 is the part of the apparatus 100 that moves with the loading/unloading of the apparatus 100. In most embodiments, the loading and loading of the apparatus 100 only involves the movement of components that comprise the tension-protrusion assembly 133.

(95) As illustrated by the block diagrams of FIGS. 2d, 3a, 3b, 3c, and 3d, the tension-protrusion assembly 133 of the apparatus 100 can include a wide variety of different shapes and sizes of protrusion components 106, tension components 112, and component configurations.

(96) As illustrated by the less abstract diagrams of FIGS. 2a, 2b, 2c, 4a, 4b, and 4c, the tension-protrusion assembly 133 will often include a protrusion component 106 in the shape of a hemisphere and a spring 122 as the tension component 112. FIG. 4c in particular displays a tension-protrusion assembly 133 that is attached to the bottom surface of the top plate 104 by a connector 24 that connects the top plate 104 to the spring 122 and with the protrusion component 106 being attached to the spring 122.

(97) Other examples of tension-protrusion assemblies 133 include FIGS. 6f, 6i, 6k, 6l, 6n, and 6o.

IV. RELATIVE MOTION/DISTANCES WITHIN THE APPARATUS

(98) As noted above, in many embodiments of the apparatus 100, only the tension-protrusion assembly moves when the apparatus 100 is loaded/unloaded. It can be useful to identify certain distances and how such distances vary between a loaded and unloaded state.

(99) A. Distance Across the Opening

(100) As illustrated in FIGS. 2b and 2c, the distance across the openings 110 in the top plate don't change with the loading/unloading of the apparatus 100, but the opening can become progressively larger as the opening 110 progresses downwards from the top surface of the top plate 104.

(101) B. Height of the Frame

(102) As illustrated in FIG. 3a, the frame 102 is typically the highest point of the apparatus 100. At a minimum, the frame height 116 must be at least as tall as the top surface of the top plate 104.
