[0114] Mounting Options for OsmoFlo Support Arm. Objective: To provide a secure and stable mounting solution for the OsmoFlo device that is compatible with a wide range of standard toilets, leveraging existing toilet bolts for ease of installation and minimal modification to the bathroom environment.

Option 1: Toilet Tank Bolt Attachment

[0115] 1. Identification: Locate the two bolts that secure the toilet tank to the toilet bowl. These are typically located at the rear of the tank, near the base. [0116] 2. Assessment: Ensure that the existing bolts have sufficient excess length protruding beyond the nut that secures the tank. The support arm attachment will require approximately 1-2 inches of excess thread. [0117] 3. Preparation: If necessary, loosen the tank bolts slightly to create enough space to accommodate the support arm bracket. [0118] 4. Bracket Installation: The OsmoFlo support arm will include a specially designed bracket with a hole. Slide the bracket onto the excess bolt thread and align it with the desired position for the support arm. [0119] 5. Secure Bracket: Use a nut (provided with the OsmoFlo kit) to securely tighten the bracket onto the bolt. Ensure the bracket is firmly in place and does not wobble. [0120] 6. Arm Attachment: Attach the OsmoFlo support arm to the bracket using the provided screws or fasteners.

Option 2: Toilet Base Bolt Attachment

[0121] 1. Identification: Locate the two bolts that secure the toilet to the floor. These are usually concealed by plastic caps, which can be easily removed. [0122] 2. Assessment: Similar to Option 1, ensure there is sufficient excess thread length on the base bolts. [0123] 3. Preparation: If needed, slightly loosen the base bolts to create space for the support arm bracket. [0124] 4. Bracket Installation: Slide the bracket (same as in Option 1) onto the excess bolt thread and align it with the desired position for the support arm. [0125] 5. Secure Bracket: Tighten the nut onto the bolt, ensuring the bracket is secure and stable. [0126] 6. Arm Attachment: Attach the OsmoFlo support arm to the bracket.

Important Considerations:

[0127] Bolt Compatibility: Ensure the hole in the support arm bracket is compatible with the thread size of the existing toilet bolts (typically inch or 5/16 inch). [0128] Weight Capacity: Design the support arm and bracket with sufficient strength and stability to support the weight of the OsmoFlo device when filled with waste. [0129] Tool-Free Installation: If possible, design the bracket and arm attachment mechanism to allow for tool-free installation, making it easier for users and caregivers to set up the device. [0130] Adjustability: Incorporate adjustability into the support arm design to accommodate different toilet heights and user preferences.

Additional Notes:

[0131] The proposed mounting mechanism leverages existing standard hardware found in most toilets, minimizing the need for modifications to the bathroom. [0132] The design can be adapted to fit various bolt sizes and configurations. [0133] This mounting approach is intended to be simple, secure, and user-friendly.
Conclusion: The OsmoFlo support arm can be mounted using either the toilet tank bolts or the toilet base bolts. Both options involve identifying the bolts, assessing the excess thread length, preparing the area if needed, installing the bracket onto the excess bolt thread, securing the bracket with a nut, and attaching the support arm to the bracket.

[0235] Other design options are contemplated and are within the scope of the present invention. For example, there are many ways that water could be provided such that it floods the interior of the funnel. For example, the funnel could be solid and there could be a water channel at the top of the channel with openings to release the water (almost like the bowl of a typical porcelain toilet). The openings could be angled holes that released the water at an angle so it swirled down the funnel, to better clean the funnel surface. Or the openings could be configured as small spray heads.

[0236] As another alternative, the spray nozzle could be the only source of water to the funnel. For example, the spray nozzle could be held in place by the clip at a location and angle such that it sprayed water onto the funnel. Once the bag had been emptied the nozzle could then be removed from the clip and the user could spray down any parts of the funnel that needed to be cleaned.

[0237] Having described above several aspects of at least one example, it is to be appreciated that various alterations, modifications, and improvements will readily occur to those skilled in the art. Such alterations, modifications, and improvements are intended to be part of this disclosure and are intended to be within the scope of the invention. Accordingly, the foregoing description and drawings are by way of example only, and the scope of the invention should be determined from proper construction of the appended claims, and their equivalents.
