Definitions
- the tools, utensils, tools or hand instruments have a handle that must be attached to the tool-tool assembly, for example, hammers, axes, hoes, etc.
- This Patent solves this problem by achieving a union of adjustment and / or precision between the handle and the tool, which is maintained without gaps through time, use and blows and is able to adjust in its adjustment-tightening, achieving maximum safety that prevents the disengagement of the adjustment and the exit of the handle with respect to the tool.
- the object of the present invention particularizes this union between handle and useful in which:
- the tool has a hole in which the handle head is embedded, the end surface of said handle head being free,
- the hole of the tool is blind by means of a front wall, in which the handle head is embedded, the end surface of said handle head being free inside said blind hole.
- the orifice of the tool is through, which consists of an entry zone and an exit zone, at least being the surface of the convergent exit zone towards the inside of the hole;
- the handle has a handle head with an incoming area and a protruding area being the outer surface of the incoming area conjugated with the corresponding one of the hole of the tool in which it is embedded, the end surface of said handle head being free and presenting the handle head an inner hole in whose exit in the outgoing zone a wedge is arranged, which when pressed in the outgoing area Ia makes conjugate with the corresponding of the hole of the tool in which it is embedded.
- Figure 1 is a longitudinal section of a practical embodiment of the object of the invention.
- Figure 2 is a longitudinal section of an alternative embodiment of the object of the invention.
- Figure 3 is a longitudinal section of an alternative practical embodiment of the object of the invention, according to Figure 2, with stop washer (1 9).
- the tool (2) acts as a female and for this purpose it has a hole (1 1) in which the head of the handle (1) that acts as a male is embedded.
- the surface of the hole (1 1) and the outer surface of the head of the handle (1) are conjugated, perfectly adjusted to each other, for example, because both have received precision machining.
- the biocaje between both surfaces is perfect.
- the surface of the hole (1 1) is convergent, that is, the surface of its section decreases along the hole, said section presenting any shape from the elliptical or polygonal circular.
- the hole (1 1) is blind, blinded by a front wall (20) that forms a unique whole with the tool itself (2).
- Said front wall (20) comprises a small hole (21) crossed by the fixing screw (7) that is indirectly screwed to the head of the handle (1) by means of a third element (3), which is fixed to said head of the handle (1).
- said hole (21) housing the screw (7) forms a countersink (22) in which a washer (6) is arranged so that the head (9) of the fixing screw (7) stops indirectly in the tool (2) and, by screwing, the head of the handle (1) can move longitudinally as a nut with respect to the fixing screw (7).
- the blind hole (1 1), the head of the handle (1), the third element (3) and the screw (7) that joins them are coaxial.
- the head of the handle (1) is adjusted with tightening in at least the mouth area (ai) of the blind hole (1 1) of the handle (1) -zone (ai) in Figure 1 -.
- the tool (2) acts as a female and for this purpose it has a through hole (1 V) in which the head of the handle (1) that acts as a male is embedded.
- the surface of the through hole (1 V) and the outer surface of the head of the handle (1) are conjugated, perfectly adjusted to each other, for example, because both have received precision machining.
- the blocking between both surfaces is perfect.
- the through hole (1 V) has an entrance area (1 1 i) and an exit zone (1 12) that are of converging surfaces towards the center of the through hole (1 V), for example two cone trunks, truncated pyramids , etc., and any one section, for example, circular, elliptical, polygonal.
- the handle head (1) has an incoming zone (Zi) and a projecting zone (Z2) whose outer surfaces are conjugated with those that present their corresponding in the through hole (1 1 ') once the wedge (5) has acted as explained below.
- the handle head (1) is embedded in the through hole (1 1 ').
- An inner hole (40) is made in the head of the handle
- the projecting zone (Z2) has a groove or expansion zone that allows its penetration / introduction by the minimum radius zone (Z3) of the through hole, the projection zone (Z2) being positioned in the exit zone (1 12) of the through hole (1 1 ') and its adjustment to said outlet surface (1 12) by means of the wedge (5), for example conical trunk.
- the projecting zone (Z2) is deformable, expandable.
- fixing screw (7) for joining the head of the handle (1) with the tool (2), having a third element (3) that is fixed to the head of the handle (1), for example, by screwing (13) of a pointed projection (12) that penetrates deeply into the head of the handle (1), or by any other conventional means.
- the body section (14) of the third element (3) can be any one.
- said fixing screw (7) forms a countersink (22) in which a spring washer (6) is arranged so that the head (9 ) of the fixing screw (7) stops indirectly in the tool (2) by means of the wedge (5) and, when screwing, the head of the handle (1) can be moved longitudinally as a nut with respect to the fixing screw (7).
- the through hole (1 1 '), the head of the handle (1), the third element (3) and the screw (7) that joins them are coaxial.
- the fixing screw (7) can be tightened more or less and the gaps that occur between the head of the handle (1) and the tool (2) in the through hole (1 1 ') can be corrected, resulting in a tight fitting in the entire friction section between the tool (2), the handle head (1) and the wedge (5).
- the fixing screw (7) is self-locking (4) incorporated into the screw itself. More particularly, the self-locking (4) is applied directly to the body (16) of the screw (7) in such a way that, in the striking, the vibrations cannot unscrew the screw (7).
- the union between said third element (3) and the head of the handle (1) is carried out in a double way:
