GUARDS

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is a continuation-in-part of U.S. Patent Application serial number 14/862,137, filed on September 22, 2015.

BACKGROUND

[0002] A typical toilet typically includes a tank fill valve and a bowl fill valve or a refill valve with a secondary emitter provided by a flexible hose that provides refill to the bowl via the standing drain. Such valves (and/or other throughways) may provide essentially the same rate of fill.

[0003] In most applications, the capacity of the tank and the bowl of a toilet are not equal.

Thus, with equal fill rates, the bowl will typically overflow while the tank is filled, causing excessive water usage. Existing solutions may require users to perform extensive installation procedures (e.g., by cutting hoses) and thus may not be removed without requiring repair or replacement the original components. In addition, existing solutions may not be reusable.

[0004] Many other applications (e.g., water bottle transport, hydration pack flow, irrigation, etc.) may require adjustable flow regulators.

[0005] Thus there exists a need for a reusable adjustable flow regulator that is easy to install and adjust and may be reused without affecting previous installations.

SUMMARY

[0006] Some embodiments provide a way to regulate flow along a flexible fluid passageway.

A flow regulator may include multiple flexible hinges, compression surfaces, and a locking element. The regulator may be able to be applied to a flexible hose or tube to restrict fluid flow through the hose or tube. The regulator may be able to be removed from the hose and reused.

[0007] The regulator may be formed from a single piece of flexible plastic. The locking element may include a protruding point and an associated set of locking receptacles or notches that run along a member of the regulator. The locking element may be positioned along the set of receptacles such that a first flexible hinge, coupled to the compression surfaces, is closed. The compression surfaces may thus engage and restrict flow through the flexible tube.

[0008] A second flexible hinge may be coupled to a member that includes the set of locking receptacles and a release lever. The second hinge may be opened using the release lever such that the set of locking receptacles disengages the locking element. Thus, the regulator may be released from the fluid passageway and reused.

[0009] The regulator may include a pair of hose guards that protrude from the compression surfaces. Such hose guards may hold a hose or tube in place along the compression surfaces as the regulator is applied to the hose or tube. In addition, the hose guards may retain the hose or tube in place after the regulator has been locked onto the hose or tube.

[0010] The preceding Summary is intended to serve as a brief introduction to various features of some exemplary embodiments. Other embodiments may be implemented in other specific forms without departing from the scope of the disclosure.

DETAILED DESCRIPTION

[0022] The following detailed description describes currently contemplated modes of carrying out exemplary embodiments. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of some embodiments, as the scope of the disclosure is best defined by the appended claims.

[0023] Various inventive features are described below that can each be used independently of one another or in combination with other features. Broadly, some embodiments generally provide ways to regulate or restrict flow along flexible fluid pathways.

[0024] A first exemplary embodiment provides an adjustable flow regulator that includes a first flexible hinge and a locking element.

[0025] A second exemplary embodiment provides a flow regulation clamp that includes a locking element, a flexible hinge coupled to the locking element, and first and second compression surfaces, each surface coupled to the flexible hinge.

[0026] A third exemplary embodiment provides an adjustable clamp that includes a locking element, a plurality of locking receptacle, first and second flexible hinges, and first and second compression surfaces.

[0027] Figure 1 illustrates a perspective view of an adjustable flow regulator 100 according to an exemplary embodiment. Specifically, this figure shows the flow regulator in an "open" or "unlocked" position. As shown, the regulator includes a flexible hinge 110, multiple compression surfaces 120 that together form a clamping element, a locking element 130, a set of locking notches 140, another flexible hinge 150, and a release lever 160.

[0028] The regulator 100 may be formed from an appropriate material and/or combination of materials (e.g., plastic, rubber, etc.). In some embodiments, the regulator may be formed from a single piece of plastic. Such a regulator may be generated using a laser cutting process, a compression molding process, and/or other appropriate manufacturing processes. The regulator may be formed in various other appropriate ways (e.g., using a mold).

[0029] The first flexible hinge 110 may be a section of the regulator 100 of appropriate rigidity and thickness that the hinge is able to be manipulated from a range of positions from fully opened as shown in Figure 2 (or even extended past that point) to nearly closed as shown in Figure 3.

[0030] Each compression surface 120 may be able to be applied to a hose or other appropriate flexible fluid passageway. Thus, in the open position of Figure 2 the surfaces 120 contact the outer surface of the hose but do not restrict flow through the hose. The compression surfaces 120 may have different surface shapes or features, as appropriate. In this example, the surfaces are flat and smooth, however some embodiments may include different textures (e.g., gripping or non-slip textures), differently shaped surfaces (e.g., surfaces including notches or other recesses).

[0031] The locking element 130 may be able to engage the locking notches 140 in a variety of positions along the range of motion of the regulator 100. In this example, the locking element 130 is an extending point that runs along the full depth of the regulator 100. Different embodiments may include various different locking elements and/or combinations of locking elements (e.g., a releasable zip tie clamp, a point and tooth clamp, a radial clamp, etc.).

[0032] Each of the set of locking notches 140 may be an inverted point, as shown, that is capable of receiving and securing the locking element 130. Different embodiments may include different numbers of receptacles 140, and/or differently spaced receptacles along the range of motion of the regulator 100. The type of receptacle 140 may be associated with the type of locking element 130 (e.g., zip tie teeth, radial clamp, etc.). The notches 140 may be coupled to the protruding release lever 160 along a member that extends from hinge 150.

[0033] The second flexible hinge 150 may be similar to the first flexible hinge and may allow the set of notches 140 to move as appropriate, as the locking element 130 is positioned along the notches 140 in order to provide a desired amount of flow regulation. Some embodiments may allow flow to be completely stopped (e.g., as during use with a wearable hydration pack).

[0034] Figure 2 illustrates a side view of the adjustable flow regulator 100 during application to a flow path. As shown, a flow pathway 200 such as a flexible tube or hose is in an unrestricted or unregulated state. In addition, the locking element 130 is disengaged from all of the notches 140 and the regulator 100 is thus in a fully open position.

[0035] Figure 3 illustrates a side view of the adjustable flow regulator 100 during restriction of a flow path along tube 200. As shown, the compression surfaces 120 may modify flow through tube 200 by applying compression to portions of the exterior surface of the tube. The compression may be adjusted by moving the locking element 130 along the set of notches 140. Flow restriction may be increased by applying pressure along path 310, thus moving the locking element 130 along the notches 140 such that the locking element 130 engages a next receptacle where the element 130 is secured in place.

[0036] The locking element 130 may be released from the notches 140, and the regulator 100 returned to the open position, by applying lateral pressure to the lever 160 along path 320, or otherwise dislodging the locking element 130 from the receptacles 140, as appropriate (e.g., by pressing a lever associated with a reusable zip tie, performing rotary manipulation of a radial clamp element, etc.).

[0037] Figure 4 illustrates a perspective view of an adjustable flow regulator 400 according to another exemplary embodiment. As shown, in addition to the features described above in reference to flow regulator 100, flow regulator 400 includes a pair of hose guards 410.

[0038] Each hose guard may be a protruding bulbous or globular finger that extends out from one end of each compression surface 120. The hose guards may be shaped such that the regulator 400 is able to be placed in a fully clamped position (i.e., the hose guards do not impede the range of motion of the hinge 110). Different embodiments may include differently shaped guards.

[0039] Figure 5 illustrates a side view of the adjustable flow regulator 400 during application to a flow path. Figure 6 illustrates a side view of the adjustable flow regulator 400 during restriction of a flow path.

[0040] As shown, the guards 410 prevent the hose from slipping out of the regulator 400 as the regulator is clamped down on the hose. In addition, the guards 410 prevent the hose from moving after the regulator has been locked onto the hose.'

[0041] In the examples of Figures 1-6, the hose or tubing 200 is perpendicular to the clip body 100, such that the clip may be opened and removed (and/or repositioned) without detaching the hose 200 or otherwise requiring disassembly of any related components. Such an approach is in contrast to, for instance, an intravenous tube clamp where the tube is parallel to the clamp such that the clamp may not be removed without detaching or disconnecting at least one end of the hose.

[0042] One of ordinary skill in the art will recognize that the regulator of Figures 1-6 may be implemented in various different ways without departing from the scope of the disclosure. For instance, different embodiments may include different numbers of locking receptacles. As another example, different embodiments may be sized differently, as appropriate for various different applications. As still another example, some embodiments may be optimized for installation and/or use in various appropriate applications.

[0043] Figure 7 illustrates a top view of the adjustable flow regulator 100 or 400 when open. Figure 8 illustrates a top view of the adjustable flow regulator 100 or 400 when closed. The regulator may be closed or opened without using tools. For instance, the clip may be placed between a thumb and index finger and pressure applied to the top and bottom of the clip such that the locking element 130 engages the notches 140, securing the clip in a closed position. Similarly, the clip may be released by moving the release lever 160 away from the locking element 130 using finger pressure.

[0044] Figure 9 illustrates a top view of adjustable flow regulator 100 or 400 during use in an exemplary application 900. In this example, the regulator is applied to a hose 910 connecting a bowl fill valve and a tank fill valve of a typical toilet.

[0045] Figure 10 illustrates a side view of the adjustable regulator 100 or 400 during use in an exemplary application 1000. In this example a cross-section view of a toilet including tank 1010 and bowl 1020 is shown. The elements of the toilet are simplified for clarity. One of ordinary skill in the art would recognize that various specific toilets of varying type, size, features, components, etc. may be used with the regulators 100 and 400 of some embodiments.

[0046] Other example applications may include, for instance, use as a water bottle (and/or other transportable object) carabiner, use as a regulator for a wearable hydration system (e.g., a backpack including a drinking water reservoir), use as a regulator for hydration systems associated with a greenhouse and/or hydroponic applications.

[0047] Different applications may include differently-sized regulators, appropriate for the size of the flow pathway to be regulated. For instance, a regulator for a toilet application may be roughly one and one-quarter inches by three-quarters of an inch by three-sixteenths of an inch. In some embodiments, the thickness of the regulator may be one-eighth inch or less, such that the regulator is able to be sent though postal mail.

[0048] The foregoing relates to illustrative details of exemplary embodiments and modifications may be made without departing from the scope of the disclosure as defined by the following claims.
