Abstract

719,186. Seats. RITTER CO., Inc. Jan. 28, 1953 [June 27, 1952], No. 2504/53 Class 52(2) A mobile vertically adjustable stool or seat, particularly for doctors, dentists or other persons, comprises a base mounted on castors, a tubular support within which is telescopically adjustable a post carrying the seat, the base being provided with feet adapted to frictionally engage the floor, when desired, to render the stool immobile. As shown the base 16 comprises a casting 19 provided with castors 26 and adjustable floor-engaging feet 73. Mounted on the base 19 is a tubular support 29 having a collar 31, the support 29 having slidable therein a centre post 47 upon which is a support plate 63 for the seat 62. The post 47 is provided with a series of annular grooves 48 with a selected one of which engages a detent 36 carried by a lever 32 pivoted at 33 in the collar 31. The lever 32 is operated to lock and unlock the post 47 by means of co-acting 34, 43, the latter being carried by a tube 38 slidably mounted on the tubular support 29 and operated against a spring 46, by a ring 39, by means of pressure from the stool occupant's foot. The feet 73, two in number, are mounted adjustably on legs 72 the upper ends 74 of which are operated upon by cams formed on the-underfaces of a hub 81 of a ring 86, rotation of which, in one direction or the other, by the stool occupant raises or lowers the feet 73 from and towards the floor. The seat 62 with its plate support 63 is rotatably mounted on the upper end of the centre post 47.
