Wearable and positionable lamp with dual light sources

A showerhead or other water-dispensing assembly () is joined to a supply pipe () by a nut () and a collar (). The supply pipe terminates in male threads (). The nut includes a distal splined projecting section (). The dispensing assembly includes a port () having a splined section (), and an inner wall (). The collar is slid onto the pipe, the nut is screwed onto the pipe, and the showerhead is held in its desired orientation while being urged toward the nut. As the distal splined projecting section enters the inner wall, the two splined sections engaged, preventing rotation of the showerhead on the pipe. The collar is then screwed onto the showerhead until it rests against the outer shoulder of the nut, thereby completing the non-rotatable installation.

A clip-on task lamp has a ball-shaped head that is pivotally and frictionally mounted between the cup-shaped ends of two tines of a ball-holding fork so that the ball-head can be rotated to any position. The ball-head has a front lens with two LEDs that are backed by a reflector. The ball has a flexible two-state pushbutton switch on the rear side and an internal battery. The base of the ball-holding fork comprises a single leg with a small swivel ball. The lamp has a clamp part that has, at its top end, two arms with two respective cup ends that hold the small swivel ball by friction fit. The base end of the clamp part comprises two legs, a shorter one of which is springably pivoted on an ear of the other. The end of each leg has a swivel pad and the shorter leg has a projection for facilitating spreading the legs so that they can be sandwiched around a member and clamped to it.

A flexible, sectioned plastic arm for a showerhead comprises a series of interconnected ball-and-socket (B&S) sections ( ) with a proximal (shower pipe) end piece ( ) and a distal (showerhead) end piece ( ). Each B&S section has a proximal (cup or socket) end ( S) and a distal (ball) end ( B). The proximal end piece has a proximal end with female threads which can be screwed onto a shower pipe and a ball-shaped distal end for snapping into the socket of the most proximal section of the shower arm. The distal end piece has a proximal end with a socket for snapping onto the most distal end section of the shower arm and a distal end with male threads ( T) which can be screwed onto the showerhead. The arm has a through hole containing a series or chain of cylindrical brass or other metal sections, tubes, or sleeves ( ). These prevent the arm from being bent too far, thereby to keep the B&S from separating. The two end tubes abut a pair of respective resilient spacers ( ) or springs ( S), which in turn abut shoulders in the end pieces to keep the series of tubes in place. Inside the series of tubes is a flexible plastic tube ( ) for carrying the water without leakage. A T-shaped end fitting ( T) is attached to each end of the plastic tube. These end fittings hold the tube in the arm. The top arm of the T of the distal end fitting sits in the bottom of the female threaded end of the proximal end piece. The top arm of the T of the distal end fitting sits on the very end of the male threaded end of the distal end piece.

A fog-free shower mirror assembly comprises a mirror body (16) and an arm (18) connecting the body to a showerhead pipe (12). The arm is connected to the pipe by a T-fitting (14) that diverts warm water from the pipe to the mirror body. The T-fitting also returns the water after it passes through a heat transfer tube (56) in the mirror body. The arm is flexible and contains two inner tubes (36 and 38) for supply and return of the water. The arm is connected to the mirror body by a swivel fitting (20). The mirror body contains a thermal transfer disc (58) positioned between the heat transfer tube and the back of the mirror. Heat from the water in the heat transfer tube is thereby transferred to the mirror to keep it above the condensation point so as to maintain it fog-free. An additional mirror (68) that also is heated by heat from the heat transfer tube may be provided on an opposite side of the mirror body, also in thermal contact with the transfer tube. The two mirrors preferably are magnifying and non-magnifying, respectively.

A condensation-free shower mirror includes a mirror (10) enclosed by a housing (12). The housing is attached to one end of a positionable arm (16), which has a C-clip (17) at another end for clipping onto a water pipe (18) of a shower head (19). The rear surface of the mirror has a protective coating or backing. Prior to shaving or other use, the mirror is positioned in a hot shower stream (20) to be heated. When the mirror is heated above the dew point of water, it will become free of condensation, and can be used for shaving or grooming, either with the hot water continuing to flow onto its rear surface, or after it is moved away from the water spray. After use, it can be easily positioned away from the shower stream so that the user can resume normal showering. The mirror can be easily detached from the pipe and easily clipped onto another, so that it can be used in different hotel rooms when traveling, as well as in the home.

A condensation-free shower mirror includes a housing (11) holding a mirror (10) and a urethane water container (18). The water container, which is substantially the same size and shape as the mirror, is fitted against the back side of the mirror. The water container is fitted with a filling-cap assembly (12) to allow a water-tight seal. Two suction cups (14) extending from the back side of the housing allows the shower mirror to be easily mounted against a shower stall or a wall mirror. When the container is filled with hot water, it heats the mirror above the dew point of water, so that the mirror will remain condensation-free in a steamy environment. Because the shower mirror can be filled with hot tap water, it is portable so that it can be conveniently used in any bathroom.

Portable condensation-free shower mirror

A condensation-free, self-supported shower mirror assembly is heated by water dispersed into a temperature-control space behind the mirror. The water is supplied by a supply tube connected from a showerhead pipe to a dispenser which disperses the heated water in either liquid or spray form, preferably from holes in a tube mounted in such temperature-control space. The tube preferably has an oval shape with the holes are formed in one of its flat sides so that when it is bent to fit around the mirror, the holes will all face inward, toward the center of the mirror. Also the tube acts as a gasket to prevent the heated water from leaking through the front of the mirror. The back surface of the mirror is thereby heated to raise the temperature of the front surface of the mirror sufficiently to eliminate water condensation thereon. In one version, mirror adjustment is accomplished through a single flex-joint, such as a hinge or a ball joint which is physically separated from the supply tube. In a preferred version, mirror adjustment is accomplished through a flex-arm which allows rotatable and translational movement. Preferably the supply tube is carried inside the flex-arm; the supply tube is mounted by friction fit in the ends of the flex-arm. A relief slot is provided in the mirror end of the flex-arm to allow water which enters the space in the flex-arm around the supply tube to leave such space. The flex-arm is attached by break-away distal and proximal joints so that the parts will not be damaged in case of trauma. The mirror is mounted in a frame with a back plate which is slightly larger than the frame so that the back plate spreads the back part of the frame, causing the front part to be compressed, thereby to squeeze the mirror into a concave shape so that it will magnify. A valve may be provided in the supply conduit (tube or flex arm) which supplies hot water to defog the mirror.

Self-supported, adjustable, condensation-free shower mirror

To prevent condensation on the mirror, it is heated with water from a supply tube connected from a showerhead pipe to a dispenser which disperses the heated water in either liquid or spray form, preferably from holes in a hose which is mounted in a rear temperature-control space and which surrounds the back of the mirror. The hose has an oval cross-section with holes on one of its flatter sides so that they will all face inward, toward the center of the mirror. Also the tube acts as a gasket to prevent the water from leaking through the mirror's front. The mirror is held by a flex-arm which includes breakaway flex-joints (hinge or ball), allowing rotational and translational movements. A supply tube is carried inside the flex-arm, has a friction fit in the ends of the arm, and is connected to the dispenser hose by a T-fitting. A relief slot in the mirror end of the flex-arm allows water which enters the space in the flex-arm around the supply tube to leave such space. The mirror is mounted in a frame with a back plate which is slightly larger than the frame so that the back plate spreads the back of the frame, causing its front part to be compressed, thereby to squeeze the mirror into a concave, magnifying shape.
