Abstract

A filterwell cartridge holder mountable within a hot tub filterwell with the filterwell cartridge holder having a handhold on one end and a feed pipe connector on an opposite end that is attachable to or removable from a filterwell feed pipe with the filterwell cartridge holder engaging and supporting dispensing cartridges thereon to maintain the dispensing cartridges in a dispensing mode within the filterwell.

First claim

We claim:

1. A filterwell cartridge holder mountable within a hot tub filterwell with the filterwell cartridge holder comprising:
a housing including a dispensing cartridge compartment located thereon;
a top end of said housing; and
a feed pipe connector on an opposite end of said housing where the feed pipe connector can be brought into or out of engagement with a feed pipe located in the hot tub filterwell.

2. The filterwell cartridge holder of claim 1 wherein the feed pipe connector includes a first extension and a second extension each resiliently yieldable to allow the feed pipe connector to be slidingly forced into or out of engagement with a filterwell feed pipe.

3. The filterwell cartridge holder of claim 2 wherein the first extension and the second extension each have an arcuate face.

4. The filterwell cartridge holder of claim 3 wherein at least one of the first extension or the second extension includes a canted end face for engagement with the filterwell feed pipe as the housing is slidingly forced into engagement with the filterwell feed pipe.

5. The filterwell cartridge holder of claim 3 wherein a distance x between an end of the first extension and the second extension is less than a diameter of the filterwell feed pipe.

6. The filterwell cartridge holder of claim 1 wherein the dispensing cartridge compartment on said housing includes a set of resilient lateral extensions for hand engagement or disengagement with a dispensing cartridge.

7. The filterwell cartridge holder of claim 1 wherein the filterwell dispensing cartridge holder includes at least two arcuate resilient extensions each having a face for angularly engaging adjacent faces of a dispensing cartridge for securement of the dispensing cartridge therebetween.

8. The filterwell cartridge holder of claim 7 wherein the housing includes a ledge for supporting a portion of a bottom face of the dispensing cartridge.

9. The filterwell cartridge holder of claim 7 wherein at least one of the arcuate resilient extensions includes a flat base face and an arcuate side face for simultaneously engaging two faces of a dispensing cartridge wherein the two faces of the dispensing cartridge are located at an acute angle to each other.

10. The filterwell cartridge holder of claim 1 wherein the filterwell dispensing cartridge holder comprises a one piece molded polymer plastic.

11. The filterwell cartridge holder of claim 1 including a stop radially insertable between adjacent pleats in a water cartridge filter located proximate the filterwell cartridge holder.

12. The filterwell cartridge holder of claim 1 including a sidewall and a flow ramp forming a portion of a water settling compartment and an end of a dispensing cartridge form a further portion of the water settling compartment.

13. The filterwell cartridge holder of claim 1 including at least two water settling compartments located thereon.

14. A filterwell cartridge holder comprising a housing having:
a set of arcuate end extensions extending over 180 degrees for being brought into forced engagement with a feed pipe through radial separation of the set of arcuate end extensions and brought into clamping engagement with the feed pipe through a resiliency of the set of arcuate end extensions;
a first set of lateral extensions each having a flat base for supporting a flared base of a dispensing cartridge therein with each of first set of lateral extensions mateable with the flared base of a dispensing cartridge located therebetween;
a second set of lateral extensions each having a flat base for supporting a flared base of a further dispensing cartridge therein with each of the second set of lateral extension mateable with the flared base of the further dispensing cartridge located therebetween;
a one end of the dispenser holder for lifting the filterwell cartridge holder out of engagement with a filterwell feed pipe or forcing the filterwell cartridge holder into engagement with the filterwell pipe; and
an extension extending from said filterwell cartridge holder with said extension insertable between adjacent pleats of a water filter cartridge to assist in maintaining a fixed orientation of the filterwell cartridge holder with respect to the water filter cartridge during operation of the water filter cartridge but not so far between the adjacent pleats so as to prevent rotation of the water filter cartridge with respect to the filterwell cartridge holder in the event an operator wants to rotate the water filter cartridge with respect to the filterwell cartridge holder.

15. A method of securing a dispensing cartridge in a hot tub filterwell comprising;
yieldably attaching a one end of a filterwell cartridge holder housing to a feed pipe in the hot tub filterwell while holding onto an opposite end of the filterwell cartridge holder housing; and
yieldably attaching the dispensing cartridge to the filterwell cartridge holder housing through engaging a set of adjacent faces of the dispensing cartridge with a set of resilient extensions on the filterwell cartridge holder.

16. The method of claim 15 including bringing the set of adjacent faces of the dispensing cartridge into face-to-face engagement with a set of mating faces on the filterwell cartridge holder.

17. The method of claim 15 wherein the step of securing the dispensing cartridge in the hot tub filterwell includes lateral insertion of the dispensing cartridge between a set of arcuate resilient extensions cantilevered laterally outward from the housing.

18. The method of claim 15 including inserting an extension of the filterwell cartridge holder between a set of pleats on a water cartridge filter located proximate the filterwell cartridge holder.

19. The method of claim 15 wherein engaging a set of adjacent faces of the dispensing cartridge comprises resiliently engaging a first face and a second face on the dispensing cartridge with a set of extensions on the filterwell cartridge holder where the first face and the second face on the dispensing cartridge and the set of resilient extensions on the filterwell cartridge holder each have adjacent faces located at an acute angle to each other.

20. The method of claim 15 including abutting a back face of the dispensing cartridge against a face of the filterwell cartridge holder.

21. The method of claim 15 wherein the the step of yieldably attaching a one end of a filterwell cartridge housing to a feed pipe comprises: engaging a canted end on an arcuate extension to an exterior surface of the feed pipe to flex the arcuate extension outward for insertion of the feed pipe into engagement with the set of resilient extensions.

22. The method of claim 15 including engaging a first socket on a filterwell cartridge holder to a first side of a dispensing cartridge and a second socket of the filterwell cartridge holder to an opposite side of the dispensing cartridge to secure the dispensing cartridge in a fixed position on the filterwell cartridge holder.

23. A filterwell cartridge holder mountable within a hot tub filterwell with the filterwell cartridge holder comprising:
a housing including a dispensing cartridge compartment located thereon and at least one water port to allow passage of water through the housing; and
a feed pipe connector on an end of said housing where the feed pipe connector can be brought into or out of engagement with a feed pipe located in the hot tub filterwell through displacement of the feed pipe connector with
