Abstract: An expandable joint for use in, for example, a headband, includes elastic material, a low-friction sleeve, and a tube. The low-friction sleeve covers at least two opposing sides of a portion of the length of elastic material. The length of elastic material is affixed to the low-friction sleeve at a first end of the low-friction sleeve or a point adjacent to the first end of the low-friction sleeve. The length of elastic material extends beyond a second end of the low-friction sleeve opposite the first end of the low-friction sleeve. The tube substantially encloses the low-friction sleeve. The low-friction sleeve is affixed to the tube at the first end of the low-friction sleeve or a point adjacent to the first end of the low-friction sleeve, and the length of elastic material extends beyond a first end of the tube.

Abstract: A set of ergonomic handgrips and arm pads make the use of crutches or other walking assist devices more comfortable and less likely to cause repetitive stress injuries. A metacarpal protrusion of the each handgrip is angled outward at about 5 to 25 degrees from front to back when installed to place the user's wrists at a more ergonomic angle (approximately 15 degrees inward rotation). The metacarpal protrusion produces a substantially flat surface with a downward slope. Each handgrip spreads the load out over the hand of the user eliminating pressure. The handgrips can be fitted on crutches, a walker, a cane, or another walking assist device. The arm pad has a pair of protrusions that produce a recess on the side facing away from a user's chest which engages a user's arm and keeps the crutch top positioned correctly while the crutch is in use by the user.

Abstract: An apparatus for receiving a plurality of toothbrushes includes a plurality of toothbrush holders and a toothbrush holder organizer. Each toothbrush holder includes a base and a cover. The base has a top and a bottom and includes a cylindrical core and an outer wall. The cylindrical core defines a cavity and includes a top end and a bottom end. The top end of the cylindrical core is open. The outer wall has a bottom end coincident with the bottom of the base and a top end attached to the cylindrical core. The cover has a hole and is operable to engage the top end of the base and retain bristles of a toothbrush in the cavity defined by the cylindrical core while allowing a handle of the toothbrush to pass through the hole. The toothbrush holder organizer includes a plurality of receptacles, each operable to receive a toothbrush holder.
