"CHAIR BACK STAND ADJUSTABLE FOR HEIGHT"
ABSTRACT
The invention relates a chair back stand adjustable
for height composed of a vertical fixed element (12), a
moving element (13) which can be vertically moved on
the fixed one and supports the back, and stop means
(19) to clamp at different heights the moving element
on the fixed one. Stop means is an oscillating lever
installed on a supporting block (21) set on the fixed
element and it is provided with a stop peg (23) which
interacts with positioning notches (18) on the moving
element and with a control push-button which contains
recovery springs.

CLAIMS
1. A chair back stand adjustable for height, comprising
a fixed vertical element (12), a moving element (13)
which can be vertically moved along the fixed element
and that supports the back, and a stop lever (19) which
can be fixed at the different heights of the moving
element along the fixed one, characterized in that:
- the fixed element (12) has a U-shaped section with
two parallel wings (12a) provided with protrusions
(16) in direction of its axis;
- the moving element (13) is vertically guided through
the parallel wings of the fixed element and it
has lateral vertical guides (17) which match with
said protrusions (16);
- the moving element (13) has positioning notches (18)
vertically set and a plate-shaped part (20) which
extends downwards and is provided with a vertical
fissure (20a) closed at the bottom through a bar
(20b);

- to the fixed element (12), between its wings (12a), a
supporting block (21) is fixed on which an
oscillating lever (19) is installed, and constitutes
a stop system to fix the height of the moving element
relatively to the fixed one, said block (21) having a
guided part in said vertical fissure (20a) which
interacts with said bar (20b) in order to avoid the
decoupling of the two elements;
2. Stand according to claim 1, in which said
supporting block (21) presents two complementary parts
connected through a joint line (21a) to open angularly
and join again parallely, and in which the oscillating
lever (19) has an intermediate oscillating axis (22)
composed of two coaxial and opposite pivots (22a) which
settle and are hold back in proper s?ats (21') formed
in the supporting block because of the opening and
closing of the two parts which form the block.
3. Stand according to claim 2, in which said
oscillating lever (19) presents on the opposite
sides of the middle oscillating axis (22) a peg (23)
interacting with the notches (18) of the moving element
(13) and a control push-button (24).
4. Stand according to 3, in which said push-button is a
single piece and has a notched shaft (24a) which
works through a jerking motion on the oscillating lever

(19), and elastic sections (24b) which lean on the
fixed element and act as recovery spring to mantain and
re-set the stop lever in the position in which its peg
(23) engages the positioning notches (18).
