Abstract
A height-adjustable sink assembly capable of continuously variable adjustment through a predetermined range of motion. The present invention includes a sink coupled to a linear motion mechanism for reciprocal movement relative thereto. The sink is supported by at least one force generating device which is actuated in response to a remotely located switch assembly. The force generating device selectively permits and restricts reciprocal adjustable motion of the sink.
Claims16
A height-adjustable sink assembly comprising:
- a sink;
- reciprocable motion means for enabling said sink to move generally parallel to a stationary wall surface for adjusting the height of said sink relative to a floor surface, said reciprocable motion means adapted to connect said sink to said stationary wall surface;
- force generating means for selectively permitting and restricting movement of said sink, said force generating means comprises at least one internally pressurized fluid device having a sealed tubular housing connected at one end thereof to said sink and defining an internal chamber therein and a piston rod, said piston rod having a piston at one end disposed for movement within said internal chamber and a second end attached to one of said stationary wall surface and said floor surface;
- and
- actuation means adapted for inhibiting movement of said force generating means when said actuation means is in a first position and for permitting movement of said force generating means when said actuation means is in a second position, said actuation means comprises a switch assembly having a switch member movable between said first and second positions and an actuation cable means adapted for interconnecting said movable switch member and said fluid control means for selectively actuating said fluid control means in response to movement of said switch member, said force generating means providing continuously variable height adjustment of said sink relative to said floor surface through a predetermined range of reciprocal motion when said actuation means is in said second position and said tubular housing attached to said sink, said pressurized fluid device further comprising fluid control means selectively actuated by said actuation means for selectively permitting reciprocable movement of said piston rod relative to said tubular housing when said actuation means is in said second position and restricting movement of said piston rod when said actuation means is in said first position.

A height-adjustable sink assembly adapted to be secured to a generally wall comprising:
- a sink;
- a vanity supporting said sink;
- a back plate adapted to be mounted to said vertical wall;
- rail means fixedly secured to said back plate in a generally planar orientation relative to said vertical wall;
- carriage means for permitting reciprocal movement of said sink relative to said rail means, said carriage means secured to a rearward surface of said vanity and adapted to capture said rail means;
- gas spring means for providing linear reciprocal movement of said carriage means relative to said rail means, said gas spring means coupled between said vanity and one of said back plate and a floor surface and having a tubular housing defining an internal fluid chamber and an axially movable piston and rod assembly disposed within said chamber, said gas spring means having fluid flow control means for selectively increasing and decreasing the length of said piston rod extending from said housing to permit continuously variable height adjustment of said sink through a predetermined range of reciprocal motion;
- and
- remote actuation means for selectively actuating said fluid flow control means such that actuation of said fluid flow control means permits reciprocal movement of said piston and rod assembly for adjusting the height of said vanity and said sink, said remote actuation means comprises a switch assembly having a switch member movable between a first position and a second position and an actuation cable assembly adapted to interconnect said movable switch member and said fluid flow control means for selectively actuating said fluid control means in response to movement of said switch member, and wherein deactuation of said fluid flow control means inhibits movement of said piston and rod assembly to maintain said vanity and said sink in a desired height position.
