DETAILED DESCRIPTION OF THE INVENTION

General Configuration:

[0041] FIG. 1 depicts one embodiment of the invention depicting a handle structure (1a) useful in 145 gripping and controlling the invention during operation and further comprising a priming conduit (2a) with shaped suction end protrusion (6a) at suction end (3) along with connection adapter (10a) at discharge end (4) for the connection of a depicted discharge conduit (12a) and with a restricting valve (5) located between ends (3) and (4) of priming conduit (2a) for the initiation of a siphon flow of liquid to provide for continuous unpowered vacuum cleaning ability.

[0042] FIG. 2 depicts an alternative embodiment of the invention alternatively comprising an adjustable length handle structure (1b) having hand grip (15) combined with attached priming conduit (2b) which alternatively includes a connection adapter (7) at suction end (3) for the adaption of various vacuuming and cleaning end devices such as depicted vacuuming end device (8) or scrub brush vacuuming end (9), plus alternatively including a threaded connection adapter (11) at discharge end (4) of priming conduit (2b) for connection of a depicted garden hose (13) for use as a discharge conduit along with a depicted debris capturing device (14) for capturing debris at the discharge end of garden hose (13), and again with a restricting valve (5) located between suction end (3) and discharge end (4) of priming conduit (2b) for the initiation of a siphon flow of liquid to provide suction for vacuum cleaning.

[0043] FIG. 3 depicts another alternative embodiment of the invention alternatively depicting a handle structure (1c) configured for multiple use, where handle structure (1c) is additionally used as the priming conduit where handle (1c) further provides the start of a liquid flow directional change to begin re-directing the liquid flow towards the downward direction. Handle (1c) further includes a shaped suction end protrusion (6c) at suction end (3) and a connection adapter (10c) at discharge end (4) for the connection of depicted discharge conduit (12c) with a restricting valve (5) located between ends (3) and (4) of handle structure (1c) for the initiation of the siphon flow of liquid for vacuum cleaning.

[0044] FIG. 4 depicts yet another alternative embodiment of the invention depicting a handle structure (1d) with shaped suction end protrusion (6d) again constructed in a manner to allow use of handle structure (1d) as the priming conduit with restricting valve (5) located between suction end (3) and discharge end (4), however alternatively designed to eliminate the need of a discharge conduit through inclusion of an extended handle length having a length and shape to provide both a directional change in liquid flow from a substantially upward direction to a substantially downward direction and with discharge end (4) located outside liquid vessel (16) and below liquid level (17), to in turn enable a siphon flow of liquid for use in vacuum cleaning.

Construction and Operation:

[0045] In each of the figures, variations of handle construction and handle usage are depicted to help emphasize the fact that the present invention can employ various shapes, sizes, as well as various materials when constructing the handle structure, and further allows for configuration of the handle for multiple uses. The handle structure for example can be constructed in a manner depicted in FIG. 3 and FIG. 4 where handle structures (1c) and (1d) are also used as a priming conduit where the handle structure further includes a suction end (3), a discharge end (4) and a restriction valve (5), in turn using a handle to communicate liquid flow. FIG. 4 further depicts handle structure (1d) also having an extended handle length and including a directional change to direct the flow of liquid to a final discharge location outside liquid vessel (16) and below liquid level (17), therefore if desired, eliminating the attachment of a discharge conduit. FIG. 1 depicts another configuration of the invention where handle structure (1a) is constructed in a manner to include a suction end protrusion (6a) at suction end (3), with priming conduit (2a) being depicted as constructed in conjunction with handle structure (1a). Yet another alternative construction method is depicted in FIG. 2, where priming conduit (2b) might be constructed separately and then retained to the handle structure through use of some common and well-known fastening means such as the depicted clamping method, or alternatively by chemical bonding, welding, use of threaded fasteners, rivets, band clamps or some other preferred fastening means. FIG. 2 also depicts an option to provide an adjustable length handle structure such as depicted by handle (1b), as well as employment of a gripping element (15) to possibly help the operator better grip the invention in a wet environment. Many common and well knowns means exist for providing elements such as a gripping element on a handle structure, for example by wrapping or fitting or coating the handle structure with a gripping material, and similarly for making a handle adjustable in length. Means for adjusting length might include the use of telescoping sections with possibly a twist lock or detent pins to maintain a selected length, or operator assembly of multiple handle sections, or some other known means to adjust handle length. These or one of one's own design or preference can be used. The invention does not limit the size, shape, or the materials needed as well as the means or manner for constructing or for the use of the handle structure in this invention.

[0046] The priming conduit of the invention can also be constructed using a preferred shape, size and material, and can include the use of one or more conduits to communicate liquid. As depicted in each of the figures, the priming conduit includes a suction end (3) a discharge end (4), and a restricting valve (5) located between, where restricting valve (5) restricts the direction of the communication of liquid to a flow direction primarily from suction end (3) to discharge end (4). The restricting valve can be of a common well-known check valve design such as the top hinged swinging disk type check valve as depicted by element (5), or a restricting valve of one's own design, however, a restricting valve within a priming conduit must be capable of opening and closing enough during the action of pushing and pulling the handle structure in an axial direction with suction end (3) and restricting valve (5) submerged in liquid, to provide for incremental filling of the liquid communication path to an elevation along that path where the liquid starts descending with the aid of gravity to the final discharge exit point, in turn initiating the siphon flow of liquid for vacuum cleaning. Orientation of the priming conduit relative to the handle structure as well as the location of the restricting valve within the priming conduit must be considered to ensure incremental filling can occur as described above. One should also consider the size and type of restricting valve use to allow passage of the desired debris size without impeding or stopping flow.

[0047] Regarding connectable vacuuming end or scrubbing end cleaning devices, for example depicted elements (8) and (9) in FIG. 2, one can employ any desired shape, size, style or material that one feels might best fit a specific need. The invention encourages construction and use of any preferred style or type cleaning end device. With regard to the connection means, for example depicted threaded suction end connection adapter (7) in FIG. 2, there exist many common and well-known means for connecting suction end devices. The same holds true for connection at the discharge end of the priming conduit to connect, for example, a preferred style or type of discharge conduit. Various means for connection can be employed such as use of a threaded connection adapter as depicted by element (11) in FIG. 2, or a barbed adapter as (10a) depicts in FIG. 1 or (10c) depicts in FIG. 3. Examples of alternative connection means might also include, but are not limited to, push-on taper friction fit connections, tapered threaded connectors, chemical bonding, welded connections, clamping, sliding fit with pins or ball detents to lock in place, Velcro, or many others. This invention does not limit one's preference in the type or style or material to use in making connection adapters at any end of any conduit.

[0048] Preference in the selection of a preferred discharge conduit is not limited by this invention either. For example, element (12a) in FIG. 1, element (13) in FIG. 2 and (12c) in FIG. 3 each depict a flexible hose or tubing type of discharge conduit. One or more discharge conduits can also be used, and of a desired size, shape or material to best fit a specific need can be employed. Attachment of a discharge conduit can be useful in directing the flow of liquid and debris to a desired discharge location. Various common and readily available products such as plastic tubing, rubber hose, garden hose, plastic pipe, etc, might be used for this purpose, however, and well known by those skilled in the art, when selecting for example the size of the discharge conduit, consideration of overall system flow volume and resistance through the communication path must be considered to ensure a sufficient volume of liquid is maintained within the communication path to the point beyond where ambient air could back up from the discharge conduit exit opening and unwantedly stop the siphoning action. Alternatively, one might choose to construct the invention so a discharge conduit is not needed by alternately shaping and extending the length of the priming conduit so as to direct the communicated liquid to a final discharge location both outside of and below vessel liquid level, however, when constructing the invention in this manner, one must still ensure that a sufficient volume of liquid is maintained within the communication path to again prevent ambient air from backing up and stopping the siphon action.

Additional Features:

[0049] A debris capturing device such as depicted filter (14) in FIG. 2 could be connected at the final discharge outlet for capturing valuables that were possibly lost within a vessel, or for capturing debris that should not be left behind. Examples of such capturing devices might be a net, filtering cloth, filter bag or perforated container. These are just a few examples of such devices that can be positioned at the final discharge outlet for capturing expelled debris.

CONCLUSION

[0050] The present invention can employ a combination of well-known and common elements as well as common and well-known construction techniques used by those skilled in the art. Because of this, the present invention provides for an economical improvement within the field of portable siphon type vacuum cleaning devices for water filled vessels such as hot tubs, spas, and swimming pools but can also be used for the cleaning of other water vessels or vessels containing liquids other than water.

RAMIFICATION AND SCOPE

[0051] Although the description of the portable siphon vacuum cleaning device above contains much specificity, these should not be construed as to limit the scope of the present invention, but merely to provide illustrations of some preferred embodiments. Thus the scope of the present invention should be determined by the appended claims below and their legal equivalents, rather than by the examples given above.
