Dismantleable tubular gripping element
It is equipped with two openings ( 1, 10 ) and has an external surface of several stretches of reduced thickness and consistent in each one of its radial cross-sections. It is of flexible material and comprises a bumpy first stretch ( 5 ) defined by parallel perimeter grooves ( 14 ). It can be used on tools, especially screwdrivers, and facilitates the coupling of the screw head to the screwdriver through one of its openings or optionally through the magnetic attraction exerted by a built-in magnet ( 8 ). Likewise, it can be applied to writing tools, such as propelling pencils or ballpoint pens.
1. A removable tubular gripping element comprising a tubular body made of a flexible material, said body comprising:
a curved surface formed by a first stretch fitted with perimeter parallel grooves, an end stretch fitted with a perimeter channel, and an intermediate stretch located between the first stretch and the end stretch,
two parallel bases defined at the ends of the curved surface, the body further comprising:
a first opening defined on one base of the two parallel bases, wherefrom inwardly a first cavity starts,
a second opening defined on the other base of the two parallel bases, wherefrom inwardly a second cavity starts,
an intermediate cavity located between the first and the second cavity, which has a bigger diameter than the first cavity,
a bend defined between said first cavity and said intermediate cavity determining a widening for the coupling of a head of a screw, and
a fixing band housed in the perimeter channel.
2. The removable tubular gripping element according to claim 1 , wherein a magnet is housed in the second cavity.
3. The removable tubular gripping element according to claim 2 , wherein the magnet is of annular cylindrical configuration.
4. The removable tubular gripping element according to claim 3 , further comprises a bearing situated inside the magnet.
5. The removable tubular gripping element according to claim 2 , the magnet is adhered in the second cavity.
6. The removable tubular gripping element according to claim 5 , further comprising an additional cavity, located between the second cavity and the intermediate cavity.
7. The removable tubular gripping element according to claim 1 , wherein both the first cavity and the intermediate cavity have a hexagonal cross section.
8. The removable tubular gripping element according to claim 1 , wherein the first cavity has a cylindrical cross-section with a smaller diameter than the diameter of the second cavity.
9. The removable tubular gripping element according to claim 1 , wherein the first stretch has a convex configuration.
