A method for retrofitting an adjustable chair including a seat, a pedestal base, and a gas cylinder that extends therebetween is provided. The method includes the steps of uncoupling the gas cylinder from the chair, and coupling a height adjustment mechanism to the chair that is configured to electrically adjust a height of the seat relative to the pedestal base. The height adjustment mechanism coupled to the chair being retrofitted includes a limit switch that is configured to limit an amount of movement of the height adjustment mechanism. The method also includes the step of coupling the pedestal base to the height adjustment mechanism.

Methods for retrofitting an adjustable chair

A chair is electrically and mechanically adjustable through a wide range of positions in a cost-effective and reliable manner. The chair includes a seat and a back coupled to a control mechanism and supported on a base. A height adjustment mechanism is coupled to a motor and extends between the base and the seat for controlling a height of the seat with respect to the base. A limit switch controls an amount of movement of the seat with respect to the base. The control mechanism is pivotally coupled between the chair seat and the height adjustment mechanism and mechanically and electrically adjusts a position of the seat with respect to the base. More specifically, the control mechanism permits mechanical adjustments of a position of the seat to be made that are independent of electrical adjustments of the seat.

Methods and apparatus for mechanically controlling adjustments of a chair

A mounting assembly for a chair that enables a plurality of mechanical adjustments to be made to the chair by a seated occupant in a cost effective and reliable manner is described. The mounting assembly is coupled to a control mechanism which includes a plurality of motor-gear groups and at least one control switch. The control switch is coupled to each motor-gear group, a rechargeable battery, and to a limit switch that limits an amount of electrical height adjustment of the chair seat with respect to the chair base. Each motor-gear group is coupled to a drive shaft and are used to electrically adjust the chair. As a result, a seated occupant may selectively engage mechanically adjust the chair seat relative independently of electrical adjustments available by the control mechanism.

A height adjustment mechanism for a chair that enables a height of a chair seat relative to a chair base to be adjusted electrically in a cost effective and reliable manner is described. The height adjustment mechanism includes an electric motor, an upper enclosure member, a lower enclosure member, and a limit switch. The lower enclosure member is coupled to the upper enclosure member, and the electric motor is coupled to at least one of the upper and lower enclosure members to telescopically move at least one of the upper and lower enclosure members relative to the remaining enclosure member. The limit switch is electrically coupled to the electric motor to limit an amount of telescopic movement of at least one of the upper and lower enclosure members.

A control mechanism for a chair that enables a plurality of adjustments to be made to the chair by a seated occupant in a cost effective and reliable manner is described. The control mechanism includes a plurality of motor-gear groups and at least one control switch. The control switch is coupled to each motor-gear group, a rechargeable battery, and to a limit switch that limits an amount of height adjustment of the chair seat with respect to the chair base. Each motor-gear group is coupled to a drive shaft. As a result, a seated occupant may engage the control switch to selectively electrically raise or lower the chair seat relative to the chair base, tilt the chair seat relative to the control mechanism, tilt the chair back relative to the chair seat, adjust the height of the chair seat relative to the control mechanism, and adjust the chair seat depth relative to the chair back.

A power kit assembly for an adjustable chair that provides power to a height adjustment mechanism to enable a chair to be adjusted electrically in a cost effective and reliable manner is described. The chair includes a limit switch that limits an amount of movement of the height adjustment mechanism. The power kit assembly includes a battery pack electrically and removably coupled to an electric motor and to the limit switch. The electric motor is coupled to the height adjustment mechanism. The battery pack includes at least one battery cell and a housing. The battery cells are axially-aligned within the battery pack housing and extend between first and second ends of the housing. The battery cells are also rechargeable.

An occupant-operated motorized vehicle is provided having a motorized front wheel assembly. The vehicle is further provided with an operator controlled lifting structure which aides the occupant in coming to a standing position. The lifting structure includes a linear actuator that is coupled to a clevis, which is in turn coupled to a shaft. Activation of the actuator causes the clevis and therefore the shaft to rotate. Attached to each end of the shaft is a lift lever that extends rearwardly away from the shaft. The end of the lever not attached to the shaft are equipped to be coupled to a support sling that is used to support the occupant and raise the occupant to a standing position. The vehicle is further equipped with a seat to accommodate the occupant in an initial seated position, and at any time that the occupant desires to be in a seated position. The vehicle of the invention also includes a hip support which is used to support the occupant in a stable, standing position and which may be adjusted vertically to enhance the support and comfort of the occupant.

A folding chair/table includes a rigid seat attached to an X-frame with four legs that fold and then slide under the seat and parallel to it for storage and a rigid backrest connected to a separate backrest frame pivotally attached to the seat, which is stopped from over rotation by the rearwardly upwardly sloping rear legs. The backrest and backrest frame pivot forwardly and downwardly to a position in contact with the front of the seat to form a table.

A cordless, power-adjustable office or task chair comprising: a seat height adjustment mechanism, including an electric motor, the upper and lower members of the adjustable column relative to each other to raise and lower the height of the seat. A seat tilt adjustment mechanism, including an electric motor, moves the top plate relative to the bottom plate to adjust the angle of tilt of the seat. A seat position adjustment mechanism, including an electric motor, moves the seat relative to the top plate. A back tilt adjustment mechanism, including an electric motor, moves the back support strap to tilt the chair back forwardly and rearwardly. A back height adjustment mechanism, including an electric motor, moves the back axially with respect to the back support strap. A seat height switch controls the seat height adjustment mechanism. A seat tilt switch controls the seat tilt adjustment mechanism. A seat position switch controls the seat position adjustment mechanism. A back tilt switch controls the back tilt adjustment mechanism. A back height switch controls the back height adjustment mechanism. Each of the switches is positioned so as to be operable by a user seated on the chair.

An improved shower head dispenser for selectively dispensing and mixing liquid additives with shower water. The shower head dispenser comprises a body having a water inlet connected to a source of water under pressure and having an outlet. The body also defines an inlet chamber communicating with the inlet and a small diameter passage connects the inlet chamber with the outlet. One or more liquid additives are contained in separate bottles or containers and each container is connected through a supply line to a manually operated valve. The valve selectively connects each supply line with an aspirating conduit which communicates with the passage in the body. The body also includes a series of the larger outer passages which connect the inlet chamber and the outlet and are located around the first passage. The flow of water through the first passage creates an aspirating action to draw the liquid additive from the desired container and mix the additive with the water which is then dispensed through the outlet. The volume of water flow through the outer passages will vary with water pressure variations, while the volume of water flowing through the first passage will remain relatively constant regardless of variations in water pressure to thereby provide a uniform delivery of the liquid additive at all times.
