## Abstract

Drain chain systems include a cap connected to a chain. The cap is configured in size and shape to enable passage of water through the drain when the cap is positioned adjacent the cap. During use, the chain is positioned within a drain and hair gathers on the chain. The chain can then be pulled out of the drain, by the cap, to remove the hair. The chain can be cleaned of entangled hair and reused, or the chain can be discarded with or without the cap, by either leaving the chain connected to the cap or by detaching the chain from the cap and replacing it with a new chain.

## Claims

### Claim 1

A drain chain system configured in size and shape to be at least partially placed into a drain of a shower or tub and to position a chain within the drain during use of the shower or tub, the drain chain system comprising:
a flexible chain that is composed of a plurality of interconnecting chain elements that are configured in size and shape to pass through the drain of the shower or tub; and
a ring attached to a plurality of spoke members that extend away from a bottom of the ring, the plurality of spoke members being connected to a central connection point below the bottom of the ring where the flexible chain is attached, the ring being configured in size for being positioned against an inner wall of the drain.

### Claim 2 (depends on 1)

The drain chain system of claim 1, wherein the flexible chain is composed of a different material than the ring.

### Claim 3 (depends on 1)

The drain chain system of claim 1, wherein the chain is connected to the central connection point with a catch that attaches to at least one of the interconnecting chain elements and that fits into the central connection point that is attached to the plurality of spoke members.

### Claim 4 (depends on 1)

The drain chain system of claim 1, wherein an opening is formed into a front side of the ring, such that the ring does not form a complete circle, and such that the ring is enabled to flex open and closed while positioning the ring against the inner wall of the drain.

### Claim 5 (depends on 1)

The drain chain system of claim 1, wherein the ring is formed from a different material than the chain.

### Claim 6 (depends on 1)

The drain chain system of claim 1, wherein the chain is detachably connected to the ring at the central connection point.

### Claim 7 (depends on 1)

The drain chain system of claim 1, further comprising at least one interactive member which is distinguished in shape from the interconnecting chain elements and which is positioned along and connected to the flexible chain, the at least one interactive member being composed of a material that is different than a material of the flexible chain and interconnecting chain elements, the at least one interactive member being configured to entangle at least some hair or other debris contained within the drain when the flexible chain is positioned within the drain.

### Claim 8 (depends on 7)

The drain chain system of claim 7, wherein the at least one interactive member is composed of a rubber material or a non-metal material.

### Claim 9 (depends on 1)

The drain chain system of claim 1, wherein the ring includes a tab, the tab being positioned on a top portion of the ring.

### Claim 10 (depends on 9)

The drain chain system of claim 9, wherein the ring comprises a diameter that is greater than one inch.

### Claim 11 (depends on 9)

The drain chain system of claim 9, wherein a hole is formed between the tab and the plurality of spoke members.
