Patent number: 4586749Abstract: A pair of link plates, each pivotally connected at one end to a seat base and each pivotally connected at their other ends to a seat plate and seat supported thereby, constrain the seat plate and seat to a rearward and upward movement, or a downward and forward movement, with respect to the seat base. The plunger, of a hydraulic cylinder pivotally carried by the seat base, is pivotally connected to the seat plate so that when actuated it induces movement of the seat plate to its rearward and upward position. A seat back is pivotally connected to the seat base and to armrests carried by the seat plate so that movement of the seat in the upward and rearward direction moves the seat back to a downward position aligned with the seat. A footrest linkage is connected between the seat back and a footrest connected to the seat so that movement of the seat back into its downward position moves the footrest into an upward position aligned with the seat and seat back.Type: GrantFiled: August 5, 1983Date of Patent: May 6, 1986Assignee: Takara Company, New York, Inc.Inventor: Masatoshi Nakatani

Patent number: 4527976Abstract: The invention relates to a dentist chair with a chair top carrying at least a chair seat. A chair bottom contains a height-adjusting system for the chair top, and at least one apparatus adaptable at the chair bottom which requires various supplies, such as air, water, electric current, which by means of supply lines are brought into the apparatus through the chair bottom from a connection box at the floor. For hookup of the apparatus the chair bottom contains a hookup portion which contains coupling means both for mechanical coupling and for coupling of the various other supply lines. The apparatus is connectible to the supply lines through a counter-piece which matches the hookup portion of the chair bottom and which, for mechanical coupling of the apparatus contains counter-coupling means which can be brought into engagement with the coupling means and which then establishes the proper required connection.Type: GrantFiled: July 22, 1983Date of Patent: July 9, 1985Assignee: Siemens AktiengesellschaftInventors: Wolfgang Behringer, Klaus Stockl, Rolf-Juergen Weiland

Patent number: 4479678Abstract: A pneumatic valve is disclosed, for controlling the position of a ram in a partly-extended condition. The valve has a combination of rubbing seals and diaphragms, for smooth operation and reliability. A spring-loaded plunger presses the diaphragm against the mouth of a port, to seal off the port. A piston with rubbing seals lifts the plunger from the diaphragm, to open the port. The piston seals rub against plastic, for freedom from water contamination problems, while the diaphragm provides the high integrity seal needed to control the ram position. A particular application of the valve is to the air control of dentist's chair, medical table or medical chair.Type: GrantFiled: July 24, 1981Date of Patent: October 30, 1984Inventor: Robert M. Sharp

Patent number: 4083600Abstract: A dental chair having a backrest and a seat each of which is angularly adjustable about a common horizontal axis. A motor drives a linkage system which simultaneously angularly adjusts both backrest tilt and seat inclination to positions ranging from one in which the chair supports the patient in substantially sitting position, to one in which the patient is reclining with his head below the rest of his body. As compared to the seat, the angular motion of the backrest is relatively uniform over the range of adjustment, whereas most of the angular motion of the seat occurs during the middle 50% of the range.Type: GrantFiled: January 28, 1977Date of Patent: April 11, 1978Inventor: Emil Hirth
-
Patent number: 4047758Abstract: A cushioned counter-balanced reclining dental chair has an underslung carriage which tilts with respect to a support to position a patient's heat at a desired work height. The angle of tilt is established by manual positioning which is facilitated by counter-balancing of the carriage, and is maintained at the desired tilt angle by a telescoping strut joined from the shoulder region of the recliner to the base. A shoulder support retains the patient's shoulders at a fixed distance from the tilt axis, independent of variations in height among patients. A buttocks engaging depression, which becomes more pronounced as the tilt of the carriage is increased to provide higher head positions, prevents the patient from sliding. The buttocks engaging depression's position is adjustable along the carriage to accomodate various body lengths, while at the same time maintaining the patient's shoulders in a shoulder cradle.Type: GrantFiled: February 23, 1976Date of Patent: September 13, 1977Inventor: Kenneth Jack Whitehill
-
Patent number: 4007960Abstract: A reclining elevator chair having a tiltable back, an extendible leg rest, and means for raising the seat and simultaneously tilting it forwardly to assist arthritic or other partially disabled persons in leaving the chair. A power-driven ram tilts the back and extends and retracts the leg rest in one mode of operation. In a second mode of operation, the same ram raises the seat and tilts it forwardly. The first mode of operation occurs when the ram is retracted below a predetermined length and the second mode of operation occurs when the ram is extended beyond the predetermined length. When the ram is equal to the predetermined length, a portion of the mechanism which tilts the back and extends and retracts the leg rest abuts against a portion of the seat frame and transfers the force of the ram from the back and leg rest to the seat.Type: GrantFiled: April 30, 1975Date of Patent: February 15, 1977Inventor: Edward J. Gaffney
