DESCRIPTION OF THE PREFERRED EMBODIMENT
FIG. 1 shows a floating dispenser holder 10 for buoyantly supporting at least two dispensing cartridges in a side-by-side condition in an immersion region of a hot tub or the like. In this example the floating dispenser holder comprises a first shell 11a and a second shell 11b with a mating edge 46 of shell 11b and a mating edge 47 of shell 11a (see FIG. 5) joined to each other along a circumferential seam 25a. A central vertical axis 23 extends vertically through a junction of the mating edge 46 and mating edge 47.
FIG. 1 and FIG. 4 show adjoining shell 11a and shell 11b forming an integral rigid center post 24, which is shown in the drawings as a part of shell 11a and a part of shell 11b (i.e., the portion between the dashed lines 24a). That is, the integral center post 24, which extends from top to bottom of the floating dispenser holder 10, is part of shell 11a and part of shell 11b.
A first dispensing cartridge platform 12 extends laterally outward in a first direction from integral rigid center post 24 and a second dispensing cartridge platform 13 extends laterally outward in an opposite direction from integral rigid center post 24 . Similarly, FIG. 1, FIG. 4 and FIG. 7 show a top portion of floating dispenser holder 10 extending laterally outward on both sides of integral post 24 to form a stylized canopy 11 where one portion of canopy 11 is part of shell 11a and the second portion of canopy 11 is part of shell 11b.
FIG. 4 shows canopy 11 extending laterally outward over a first two-part dispensing cartridge engagement platform 12 on one side of post 24 and a second two-part dispensing cartridge engagement platform 13 on an opposite side of post 24. In this example platform 12 cradling holds a lower end of a first dispensing cartridge 20 in a dispensing condition on one side of floating dispenser holder 10 and similarly, the platform 13 cradling holds a lower end of a second dispensing cartridge 21 in a dispensing condition on an opposite side of floating dispenser holder 10 as the floating dispenser holder 10 and the dispensing cartridges thereon float about in a body of recreational water such as a pool, spa hot tub or the like.
In the example shown in FIG. 1, FIG. 4, FIG. 6 and FIG. 7 the first dispensing cartridge platform 12 includes a first resilient, acutely-angled extension 12a and a second resilient, acutely-angled extension 12b that each cantileverly extend laterally outward to clamp and support a dispensing cartridge 20 in a dispensing condition on the floating dispenser holder 10. Similarly, a second identical dispensing cartridge engagement platform 13, which includes a first resilient lateral acutely-angled extension 13b and a second resilient lateral acutely-angle extension 13a (FIG. 6) each cantileverly extend outward to clamp and support a second dispensing cartridge 21 in a dispensing condition, which is shown in FIG. 4. An example of a base support for a dispensing cartridge can be found in applicant’s copending application SN 16/873,295 filed 3/11/20, which is hereby incorporated by reference.
Although the example shows identical platforms for supporting identical dispensing cartridges thereon the shape of platform 12 and platform 13 may be different from each other support to different types of dispensers thereon without departing from the spirit and scope of the invention.
The floating dispenser holder 10 contains sufficient buoyancy to support itself and a first dispensing cartridge 20 and a second dispensing cartridge 21 in either a spent or unspent condition with the water ports of the dispensing cartridges located below a waterline with at least a top portion of the canopy 11 visible above the water line. That is, when both the first dispensing cartridge 20 and the second dispensing cartridge 21 are in an unspent condition the floating dispenser holder 10 free floats in an upright condition within a body of recreational water. If desired one end of a cord (not shown) can be anchored and the other end extended through eye 22 (FIG. 1) of floating dispenser holder 10 to restrain the floating dispenser holder 10 from free floating about in a body of water.
FIG. 5 is an exploded view showing floating dispenser holder 10 comprises a two-part shell i.e a first shell 11a having an open side with a mateable peripheral edge or face 47 and a second shell 11b having an open side with a mateable peripheral edge or face 46. FIG. 5 also shows a float 31 that fits partially within a hollow of the first shell 11a and partially within a hollow of the second shell 11b so that when shell 11a and shell 11b are secured to each other along peripheral faces 46 and 47, as shown in FIG. 7, float 31 provides sufficient top floatation to support a top portion of floating dispenser holder 10 above waterline 9 while dispensing cartridges 20 and 21 are supported in a dispensing condtion below the waterline 9 as shown in FIG. 8A.
A feature of shell 11a is that shell openings such as openings 25, 34 and 34a in shell 11b (see FIG. 1) as well as identical openings in shell 11a (not shown) allow water into the interior space of the floating dispenser holder 10. The water contacts float 31 as air is allowed to escape either through openings in the shells, an air hole 11d (FIG. 5) or along a circumferential seam 25a where face 46 and face 47 adjoin each other. Consequently, the top central location of float 31, as shown in FIG. 6 and FIG. 7, provides a central top buoyant force that maintains floating dispenser holder 10 in an upright dispensing condtion as illustrated in FIG. 8A. That is, the weight of dispensing cartridges 20 and 21, which are supported by lower platform 12 and platform 13, exert a downward force on the bottom of floating dispenser holder 10 creating a bias for the floating dispenser holder 10 to float upright about a vertical axis 23. In this example a protrusion 19 is shown that may be used to hinder rotation of a dispensing cartridge located in the dispensing cartridge platform 12.
FIG. 5 and FIG. 6 shows shell 11a having a smoothly contoured outer face 11c and a dispensing cartridge platform 13 having a resilient, acutely-angled extension 13a and a resilient, acutely-angled extension 13b on one side integral post 24 linking the dispensing cartridge platform 13 to shell 11a. Similarly, shell 11b includes a smoothly contoured outer face 12c on one end and a dispensing cartridge platform 12 having a resilient, acutely-angled extension 12a and a resilient, acutely-angled extension 12b on one side of integral post 24 linking the dispensing cartridge platform 12 to shell 11b.
Integral post 24 is formed when shell 11a and shell 11b are abutted to each other as shown in FIG. 1. As shown in FIG. 1 and FIG. 4 integral post 24 has an upper end supporting a canopy 11 that extends laterally outward from both sides of post 24. The canopy 11 shields the top of dispensing cartridges 20 and 21 from a person or persons within the body of water. During use canopy 11 remains visible above a water line while the set of cartridge supporting platforms 12 and 13 remain below the water line thereby maintaining dispensing cartridges 20 and 21 in a dispensing condition.
Located within shell 11a are male latches 48 and female latches 49 (FIG. 5) that can be engaged with each other by abutting shell 11a and shell 11b to each other as shown in FIG. 7. To aid in alignment of shell 11a and 11b one can include alignment extensions 53 on shell 11a and alignment extensions (not shown) on shell 11b to assist in mating assembly of shell 11a and 11b.
FIG. 5A shows a side view of a male latch comprising a resilient link 48, which can flex upward, with a hook end 48b and a hook guide 48a positioned next to a rigid female latch 49 having a pocket lip 49b located in pocket 49c.
FIG. 5B shows a top view of the male latch 48 and female latch 49 in alignment prior to displacement of the latch 48 and latch 49 toward each other which causes hook guide 48a to force male latch 48 to flex upward during a forward motion of male latch 48 with respect to female latch 49. FIG. 5C shows the male latch 48 in engagement with female latch 49 as the resiliency of male latch 48 brings the latches into latching engagement with each other. That is, lip 49b at the end of male latch 49 is in pocket 49c and in engagement with lip 49b. Typically, two or more latches may be used to secure shell 11a to 11b.
A feature of the male latch 48 and the female latch 49 is that the latches are self-engaging. That is as shell 11a and shell 11b are brought into face-to-face contact with each other each of the male latches flex to engage each of the female latches. Thus, a set of latches on shells 11a and 11b allow one to assemble a single smoothly contoured dispensing cartridge 10 with a stylized canopy from two mating shells that are locked or latched to each other without the aid of tools. The internal latching of the floating dispenser holder shell 11a and shell 11b prevents accidental separation of the dispenser holder 10 shells by a person or persons in a body of water since the latches 48 and 49 become inaccessible from the exterior of the floating dispenser holder10 once the floating dispenser holder 10 is assembled.
FIG. 7 reveals a ballast compartment 29 on the lower end of holder 10 with the ballast compartment 29 comprising a cylindrical housing 29a mateeable with a cylindrical housing 29b in shell 11a to form a closed centrally positioned ballast compartment 29 as shown in FIG. 7. Typically, a weight can be placed in ballast compartment 29 to ensure that the floating dispenser holder 10 maintains a bottom heavy condtion that causes the floating dispenser holder 10 to float in an upright dispensing condtion as shown in FIG. 8A as the ballast compartment is located along a vertical flotation axis 23. Thus, the floating dispenser holder 10 can be mated to dispensing cartridges to ensure that the floating dispenser holder 10 floats in the desired orientation. For example, in the event the weight of the contents of the dispensing cartridges on the floating dispenser holder differ substantially from each other.
Also Located within the floating dispenser holder 10 is an internal skeleton framework 26 (see FIG. 5 and FIG. 7) that supports a smooth outer facade of the floating dispenser holder 10 thereby providing a stylized outer appearance to the floating dispenser holder that blends with an external facade of a hot tub. A portion of the skeleton framework 26 is illustrated in cut away view of FIG. 7 that shows the ballast compartment 29 formed in the lower portion of dispenser holder 10. As described the ballast compartment 29 allows one place a weight on the bottom portion of the floating dispenser holder 10 to thereby introduce a bottom-heavy feature to the floating dispenser holder 10 as the weight of ballast therein encourages an independent upright vertical flotation of the dispenser holder as shown in FIG. 8 and FIG. 8A, which shows the floating dispenser holder 10 floating in a sitting area 40a, which is outside of the filterwell 42 of the hot tub 40. FIG. 8 reveals that the low, above water profile of the floating dispenser holder 10 and the portion located below the water line discourages the floating dispenser holder 10 from floating on top of the skimmer port 56, which could block the flow water into the skimmer port.
FIG. 6 and FIG. 7 show the top central placement of float 31 with float 31 held in position by float stops 26 proximate each end of float 31. Thus, in this example the float positioned in a top central location provides a flotation balance force that causes the floating dispenser holder 10 to float in an upright condtion as shown in FIG. 8 and FIG. 8A. In the example shown float 31 comprises a closed cell foam 31 that is centrally confined within an upper portion of the canopy 11 with a central axis 23 of the floating dispenser holder 10 extending through a center of the float 31 that is alignment with the central vertical axis 23.
FIG. 2 is a side view and FIG. 3 is a bottom view of an example of a dispensing cartridge for removably mounting in the floating dispenser holder 10 with the cartridge 20 having an angled face, i.e., a flared base 36 with a pair of triangular shaped opening 36b therein to allow water access to the underside of dispensing cartridge 35 when the cartridge is located on a dispensing cartridge platform. FIG. 3 shows the underside of dispensing cartridge 35 having bottom ports 35a and 35b to permit the ingress and egress of water into a dispersant located within the dispensing cartridge 35. A top air hole 37, shown in FIG. 2 lets air escape from the cartridge 20 as water enters the dispensing compartment therein. In this example cartridge 20 has an annular angled rim 36 with a face 36a that forms a locking engagement with a resilient, acutely-angled extension 12a and a resilient, acutely-angled extension 12b that mates with the dispensing cartridge platforms on the floating dispenser holder 10. An example of a dispensing cartridge 35 is shown in applicant’s copending application SN 16/873,295, which is hereby incorporated by reference.
FIG. 8 shows a hot tub 40 having a seating area 8, which is located outside of the filterwell 42 of the hot tub. Located within the hot tub and partly above the water line 9 of water 9a is floating dispenser holder 10. FIG. 8A is an isolated view of the floating dispensing holder 10 as it floats on the body of water within the hot tub while supporting dispensing cartridge 20 and dispensing cartridge 21. A feature of the floating dispenser holder 20 is that the underwater profile of the floating dispenser holder 20, which is illustrated in FIG. 8A, is such that if the floating dispenser holder 20 floatingly contacts a hot tub skimmer 56 it is unlikely to block the skimmer port 50a since the below water portion of the floating dispenser holder 10 acts as a bumper to prevent the floating dispensing dispenser holder from blocking skimmer port 50a of the skimmer 56. While the invention shown herein discloses two cartridges supported on the Floating Dispenser Holder the Floating Dispenser Holder may be used to support a single dispensing cartridge without departing from the spirit and scope of the invention.
