A light comprising an LED whose light intensity decreases as the angle from an axis of the LED increases, and a convex lens associated with the LED such that a beam width of the LED is concentrated by the lens into a narrower beam width, wherein the convex lens includes both a convex surface and a concave surface, and the concave surface is curved more sharply towards its edge than towards its center such that light is more evenly spread across the beam width of the lens.

LED work light

Work light has LEDs that require heatsink. Desired radiation pattern achieved by using optical components designed to produce beam or LEDs may have beams in different directions. Radiation pattern of LEDs may be changed by refractive-reflective optics or by convex lenses. Convex lenses may be hemispheres, other planoconvex shapes, concavo-convex shapes, or other shapes. Curved surfaces on any lenses may be spherical or aspheric. Ballast to operate the LEDs from line voltage AC or low voltage DC. Work light may contain batteries. The work light may be mounted on a stand. May have accessory mount. May have charging station. May have a paging transmitter to activate a paging receiver in work light. May have openings for heat transfer from heatsink to ambient air external to light.

Housing is generally tubular and split into two longitudinal hinged halves. Housing receives threads on driver. Retention and anti-rotation means retain cartridge in other end of housing. Cartridge has zero draft tubular wall, and rounds to an extended tip with external threads at other end. Tip is hollow. Piston matching profile to tip and seals open end of cartridge. Liquid is contained between tip and piston. In use, driver engages piston to force liquid out tip. Cartridge differentiates between capacities of cartridge for housing. Driver and housing indicate rotary position of driver with respect to housing and prevent driver from reversing direction. Injector is designed to withstand pressures of operating system to which liquid is injected. Injector high accuracy for use with high concentrations and small cartridges. Cartridge and piston limits introduction of air when filling and limits retained liquid after cartridge used. Housing and driver indicate liquid remaining.

A brake handle assembly for actuating a brake of a wheeled walker of the type having a handle bar member slidably received for telescopic movement within the upper end of a leg member, a wheel rotatably mounted at the lower end of said leg member, a brake mounted at the lower end said leg member, and an elongated brake rod disposed within said handle bar and leg member for moving said brake into and out of braking engagement with said wheel. The brake handle assembly provides a linear pull non-cable brake actuation and is manually operable between a neutral position, a raised brake actuating position and a depressed brake locking position.

The present invention relates to a cordless braking system for a mobility-aiding device, such as a wheeled walker (a rollator) or a transport chair. The cordless braking system includes a brake actuating linkage, disposed inside the leg and handlebar members of the mobility-aiding device, which extends during height adjustment of the handlebars. The brake-actuating linkage and the leg/handlebar of the mobility-aiding device are designed to enable a locking pin or bolt to extend all the way therethrough to ensure that all of the height-adjustable members are secured together during use.

An LED inspection lamp has plurality of LED sources for emitting electromagnetic radiation at different peak wavelengths for causing visible fluorescence in different leak detection dyes. A lens is associated with each LED. Radiation passing through lenses is superimposed in target area at target distance. Another LED inspection lamp has plurality of LEDs emitting electromagnetic radiation at a peak wavelength. A lens adaptor has lens housing for attachment to LED inspection lamp with a single LED for causing visible fluorescence, and a lens. Substantially all of the radiation from the LED passes through the lens and is focused in a target area at a target distance from the lenses. LED spot lights have a similar configuration. The LEDs may produce white light from distinct LEDs or from white LEDs. The light may be a flashlight or fixed spot light.

A mobility aiding device, such as a walker, a wheelchair, a transport chair, a shower seat or a rollator, are used in providing support to injured or ailing persons during activity or movement. A solid two-piece seating platform is provided with a structural support for distributing the weight of the user to the frame. Furthermore, the two pieces of the seating platform are inter-hinged, enabling the entire device to fold up into a storage position. A lock is provided for maintaining the structural support in place, and a handle is provided for facilitating folding the device into the storage position.

A duster cleaning member derives its suction power from a vacuum cleaner to which it is operatively coupled. A duster made of any material received thereby is cleaned by the filtration system of the vacuum cleaner which captures the dust and exhausts cleaned air back into the home or office environment.

A wheeled walker convertible to a transport chair. The walker has a strap-type backrest that is pivotally attached to the upper end of the handlebars. The backrest can be placed in a forward position when the apparatus is used as a walker and the user wishes to rest in a rearward facing sitting position and in a rearward position when the apparatus is used as a transport chair and the user sits in a forward facing position and is propelled by a care-giver. A novel braking system locates the brake actuating linkage inside the leg and handlebar members and provides accommodates extension height adjustment of the handlebars. A brake lever system providing a linear pull non-cable brake actuation is also disclosed.

Combination walker and transport chair

A wheeled walker having a moveable carry basket. The walker has a carry basket mounted between the front leg members. The mounting arrangement permits the basket to be moved between a first position in which the basket projects forward of the front leg members for ease of loading and unloading and a second position in which the basket is displaced substantially rearward of the front leg members under the seating surface.
