| 123 | Quick crank adjustable height table | US10514697 | 2003-06-06 | US07412931B2 | 2008-08-19 | Lon D. Seidl; James A. Tierney |
| A table or desk assembly (20) includes a base having a pair of legs (24), a worksurface (22) supported by and between the pair of legs, and a rapid, counterbalanced height adjustment mechanism interposed between the legs and the worksurface for providing adjustment in the elevation of the worksurface. The height adjustment mechanism includes a pair of high lead rotatable threaded rods (32) engaged with a mating stationary threaded member (33) associated with each leg. A handle (36) is engageable with one of the threaded rods for imparting rotation to the threaded rod, and a synchronizing arrangement, such as a sprocket (38) and chain system (40), is interconnected with the other of the threaded rods for rotating the threaded rods together. A lift assist or counterbalancing mechanism applies an upward bias, such as to the worksurface, to counteract the weight of the worksurface and any loads supported by the worksurface. The counterbalancing mechanism may be in the form of a cylinder assembly (54) having a biased retractable and extendible member, which is interconnected with each of the threaded rods via a cable (66) and pulley (68) arrangement. Alternatively, the lift assist or counterbalancing mechanism may be in the form of constant force spring arrangements (76), each of which has an extendible and retractable member. A retainer arrangement (90) is interposed between the crank or handle member (36) and the worksurface, for preventing inadvertent rotation of the threaded rod and thereby maintaining the elevation of the worksurface. | ||||||

| 129 | Height adjustable table | US09768934 | 2001-01-23 | US06546880B2 | 2003-04-15 | William Michael Agee |
| An adjustable height table has a frame with spaced apart side portions spanned by a horizontal tray with a knee area below the tray. Each side has a foot that engages the floor or like support surface. Each side includes a lower non-elevating base part and an upper elevating “lift” part. The non-elevating and elevating portions each have an outer wall, a hollow interior and vertical slots that face in opposite respective directions for a given side (including a non-elevating portion and an elevating lift portion). A gear mechanism interfaces the upper “lift” and lower “base” parts. When the table is in an extremely elevated position, roller supports minimize lateral translation. The roller supports fit shaped rails on the elevating parts. The frame can receive any of three selected mechanisms. Each mechanism features a horizontal shaft contained within the tray. The mechanism includes a counterbalance spring that can be used to counterbalance loads of different amounts such as when different objects are supported by the table work surface, a motor drive that changes elevation using electrical power, and a manually operable crank mechanism. | ||||||
| 130 | Self-braking height adjustment mechanism | US865360 | 1997-05-29 | US5941182A | 1999-08-24 | H. Peter Greene |
| A vertically adjustable workstation comprises one or more legs having a vertical adjustment mechanism which provides an automatic self-braking function. The vertical adjustment mechanism comprises a highly efficient rotating member, such as a ball screw and ball nut assembly. Securely attached to the ball screw and the work surface is a clutch mechanism. The clutch mechanism has on one end a friction cap which is frictionally engaged with the work surface, and a thrust bearing which provides a first rotational interface between the ball screw and the clutch mechanism. The clutch mechanism comprises a roller clutch which allows for free rotation of the ball screw in the upward direction and is engaged with the ball screw when rotated in a downward direction. This arrangement comprises a load path which is directed from the work surface through the mating friction surfaces, the clutch mechanism and thrust bearing into the ball screw. The frictional rotational interface between the table and the friction cap of the clutch mechanism provides the self-braking feature such that backwinding of the table is prevented. A collapsible handle is operatively connected to the ball screw. | ||||||
