Abstract
An arm height adjustment mechanism for a chair of the type having a pair of laterally spaced, fixed armrest supports. The mechanism includes first and second armrests slidably mounted on said supports for vertical movements. A vertical motion translation mechanism interconnects said armrests so that vertical movement of one armrest translates to synchronized, simultaneous vertical movement of the other armrest.
Claims23
An armrest height adjustment assembly for a chair having a pair of laterally spaced, fixed armrest supports, said assembly comprising:
- a first armrest slidably mounted on one of said supports for vertical movement;
- a second armrest slidably mounted on the other of said supports for vertical movement;
- and
- vertical motion translation means interconnecting said armrests for translating raising or lowering movement of said first armrest to said second armrest so that vertical movement of said first armrest causes synchronized, simultaneous vertical movement of said second armrest.
A vertical arm height adjustment mechanism for a chair which has a pair of laterally spaced armrest supports, said mechanism comprising:
- a first armrest assembly mounted for vertical movement on one of said supports;
- a second armrest assembly mounted for vertical movement on the other of said supports;
- a first elongated member having an end fixed to said first armrest assembly for up and down movement therewith;
- a second elongated member secured to said second armrest for moving said second armrest assembly up and down;
- motion translating means interconnecting said first elongated member and said second elongated member for moving said second member in an upward direction upon upward movement of said first armrest whereby vertical movement of said first armrest translates to synchronized vertical movement of said second armrest.
A chair of the type including a base, a seat mounted on the base and a back, said chair further comprising:
- a generally U-shaped tubular armrest support including a pair of open ended support uprights joined to an elongated base, said base extending under said seat;
- a pair of armrest assemblies, each assembly having a tubular portion telescoped on one of said support uprights;
- vertical motion translating means within said armrest support and operatively interconnecting said armrest assemblies for translating vertical movement of one of said assemblies to vertical movement of the other of said assemblies.
