Background Presently while working on high altitudes workers wear safety belt with 1.5 m length. The drawbacks of these safety belts are: 1) The mobility of the worker is restricted to 1.5 m radius. 2) The restricted mobility compels worker to frequent hook and unhook the safety belt end as he moves beyond 1.5 m, causing fatigue. 3) Worker is tempted to discard safety belt, throwing safety to the wind.

Detailed Description Of Preferred Embodiments
Figure 1 shows isometric view of High Altitude Safety Gear shows hook at the top, which is engaged at desired location in working area.
This has basically a winding drum with gearwheel Spiral spring of which one end is fixed with the drum and other riveted to 10 m nylon belt, which remains wound on the drum due to spiral spring Tension.
The winding drum rests on a fixed shaft with both ends of the shaft keyed. Nylon belt end is passed through Top guide rollers and then through bottom guide rollers and has hook at the end, which can be fitted to safely belt on worker's body (Nylon Belt 11 in fig. 3)

Fig 4 shows assembly of Floating Top guide rollers with the second geared wheel (4), coil springs which enable to maintaining gap of preferably 10-12 mm between a second gear wheel (4) of guide rollers and a first gear wheel (5) of winding drum (8). The first gear wheel (5) on winding drum (8) rotate in clockwise direction where as the second gear wheel (4) on Top guide roller rotate in anticlockwise direction.
Now the worker can safely and freely work in a radius of 10 m. After finishing the work belt is disengaged from the body belt and belt gets wound on the winding drum automatically due to tension in the spiral spring.
In case of fall of a worker the gravitational force due to body weight on the belt brings down the floating guide rollers compressing coil springs and the second gear wheel (4) of lower Top guiding gears get meshed with first gear wheel (5) on the winding drum (8). Guide roller gears rotate in a anticlockwise direction where as those on the winding drum rotate in opposite direction i.e. clockwise.
Thus the winding drum is locked preventing any further downward slipping of the Nylon belt making the belt taut on Top & Bottom guide rollers (fig. 5 & 6)
Fig 5- Shows coil springs compressed and Top guide roller gear wheels (4) meshing (locking) with gear wheels (5) on the winding drum (8).
Fig. 6- shows nylon belt is taut on Top & Bottom guide rollers.

I claim,
1. A safety-gear comprising:
a winding drum (8) with a first geared wheel (5) provided on a fixed shaft (7) configured in said body (9), characterized in that
a floating top guide rollers (1) with a second geared wheel(4) provided on a movable shaft (3) configured in said body (9), wherein the second geared wheel(4) of floating top guide roller (1) is configured to selectively mesh with the first geared wheel (5) of the winding drum (8);
one or more coil springs (6) provided between the moveable shaft (3) and the
fixed shaft (7);
a bottom guide roller (10) configured in said body (9); and
a nylon belt (11), the one end of the nylon belt (11) is attached to the winding drum (8) and the other end of the nylon belt (11) is configured to pass through the floating top guide rollers (1) and bottom guide rollers (10) and freely protrudes outside said body (9).
