ITTS980017U1 - SINGLE LEG CHAIR - Google Patents

Description

Composition:

• The “Istra 2000” chair is made up of an anatomic seat, a telescopic support leg and a system of belts.

1.1: anatomic seat

The seat was modeled following the principles

ergonomics of the human body. It can be made in different materials. In fact, the use of wood and canvas covering with

relative padding, or in plastic material.

1.2: telescopic support leg

The support leg is fixed to the seat by means of four screws [see plan and section drawings]. This leg is divided into two pieces (interpenetrating tubes) which allow correct height positioning thus adapting the structure to different body sizes. The "leg" rests on a reinforced rubber end (non-slip) or on an "L" profile or on a disc. This expedient allows you to use the tool even on non-hard surfaces such as sand, earth, etc.

1.3: locking straps

The locking straps are attached to the seat

by means of special holes [see top view and relative

sections]. Attachment to the human body is guaranteed by

special carabiners or quick hooks.

The straps can be adapted to any body-

rature.

The particular “cross structure” [see modalities view

of use] allows proper operation by doing

so that the leg does not make a slight angle with the ground

less than 90 ° with respect to the body structure Said

expedient allows the user a balance not

precarious.

I How to use

The chair can be used for several purposes:

1) work in the countryside: ideal for jobs such as harvesting vegetables, working in the vineyards; 2) gardening: working indoors such as greenhouses (lack of space for any chairs); 3) livestock farms: milking, shearing, etc .;

4) artisan works: possibility of movement in different points of an artisan workshop and the possibility of having your hands free for a

possible transport of tools;

5) photography: sports or naturalistic photos on land that require long waits and consequent reduction

physical effort [see attached photos], ·

6) hunting and fishing: long stalking

on different terrain topologies;

7) topographic surveys.

Claims (5)

Add the following claims: “1. Single-leg seat with improved means for its attachment to the user's body comprising an anatomical seat, a telescopic support leg and means for joining the user's body, characterized in that the means for joining the seat to the user's body are constituted by a belt system sized in such a way as to simultaneously engage both the thighs individually and the lower part of the user's torso, automatically imparting the correct position to the support leg, a position that will be maintained even when the user moves from a point to the other on the ground. 2. Single-leg seat having improved means for its attachment to the user's body comprising an anatomical seat, a telescopic supporting leg and means for joining the user's body, according to claim 1, characterized in that the locking straps are fixed to the seat by means of special openings (la, lb, le, ld) and the fixing to the human body is guaranteed by special carabiners or quick hooks (Al, A2, A3) which allow the full engagement of the user's body through a harness Single "inguinal" of the thighs and radial wrapping of the lower part of the torso with crossing point (A4) of the belt system (3), consisting of a loop, preferably but not exclusively in metal such as a double metal ring, or an elongated buttonhole , placed in correspondence of the third / fourth lumbar vertebrae. 3. Single-leg seat with improved means for fixing it to the user's body comprising an anatomical seat, a telescopic support leg and means for joining the user's body, according to the preceding claims, characterized in that it provides a system of belts (3) comprising: a belt functionally defining two parts (3a, 3al) for securing the waist, said parts being respectively about 120 cm and 80 cm long; a belt functionally defining two parts (3b, 3bl) for securing the thighs, each of these parts being about 60 cm long; a pair of straps (3c, 3cl) each about 14 cm long and a pair of front straps (3d, 3dl) each about 15 cm long, all defining the rear crossing point (A4) at a height of about 10/12 cm from the seat surface (1) and therefore in correspondence with the third / fourth lower vertebra. 4. Single-leg seat with improved means for its attachment to the user's body comprising an anatomical seat, a telescopic supporting leg and means for joining the user's body, according to the preceding claims, characterized in that it provides a leg (2) formed with two pieces (2a, 2b) of metal tube with a section, for example, circular, of different diameter so as to define a telescopic leg joined at the top to a seat (1), anatomically shaped and substantially triangular in shape, by means of an intermediate plate ( 4) having a seat (4a) to accommodate the extremity of the upper part of the thickness (2a) of the leg (2), and the reciprocal positioning of the two pieces (2a, 2b) constituting the leg (2) is guaranteed by the presence on the fixed piece (2a) of at least one transverse hole (2c) and on the movable piece (2b) of several holes (2d, 2e, 2f. 2g, 2h) and of a stop (2i) consisting of a cotter pin, a rod or tro, adapted to coaxially engage the mating holes of the lengths (2a, 2b). 5. Single-leg seat with improved means for its fastening to the user's body comprising an anatomical seat, a telescopic support leg and means for connection to the user's body, according to the preceding claims, characterized in that the leg (2) is provided with a non-slip foot (5) of any shape, for example "L" -shaped, disc-shaped, toe-shaped, providing means to reduce its penetration into the support surface, to allow the seat to be used on different surfaces, therefore not only on hard surfaces but also sand, earth, or other.
