Description

Additional jaws for adjustable mechanism for socket wrenches.

Object of the invention

Additional jaws for mechanism Adjustable for socket wrenches can be fixed to the jaws own mechanism in their areas of fit and allow to establish a range of screw embrace measures larger than those can be established with the jaws of the mechanism mentioned, when it is possible to start the new range of measurements where the end of the jaws cited.

State of the art

Adjustable mechanism for socket wrenches has as a goal and allows you to adjust your mobile jaws to a wide range of screw measurements making unnecessary the numerous glass pieces that must accompany the keys of this typology.

However, this mechanism has as inconvenient that while its measures are acceptable for use in screws greater than their range may be excessive for the smaller screws of the same.

Additional jaws for mechanism Adjustable for socket wrenches complement the jaws of the mechanism allowing with given dimensions of said mechanism can be established screw hug measures higher than those that allow the integrated jaws in the tool.

Description of the invention

Additional jaws for mechanism Adjustable for socket wrenches allow once fixed at jaws of the mechanism establishing an interval of measures between said additional jaws greater than those enable the jaws of the mechanism for the grip of screws. Thus they allow to reduce measures of the mechanism and can be extracted from the same according to convenience of use.

They can be fixed to the jaws of the mechanism in its extreme areas intended to fit with the screws well placed against them on the back side of that of fit on the screws or they can be placed on the mechanism jaws coupled around it so fair enough. Also note that its use is in pairs the two pieces being identical in order to be placed in both adjustable mechanism jaws for socket wrenches indistinct

Turning to the description of the invention this is refers first to an additional jaw that is placed against the rear wall of the jaw of the mechanism remaining fixed on her.

Said additional jaw has an elongated shape, of basically rectangular perimeter and is divided into two zones at along its length that are an area of coupling to the jaw of the mechanism and another one destined to fit against the screw on the one to act, in two of opposite angles or on parallel sides of the same. To be able to adjust the additional jaw over angles opposite of the screw this presents from its end to a point internal in which a suitable angular recess is closed to said angles centered on its width and if it fits only over parallel sides of the screw the fitting area can be smooth from the end to an interior point where a step continues outstanding that will prevent a possible screw exit.

As for the coupling area of the additional jaw with the mechanism jaw preferably the first one is fully fitted against the second one to which squeezes during rotation laterally allowing you to offer full width resistance. For this purpose the sides of the jaw of the mechanism that define it in its thickness have oblique orientation opening from its contact surface with the additional jaw being its union with it by vertex or curved wall where the vertex or curve that fits completely are drawn between the contact wall of the additional jaw with the previous one and the side walls that stand out opening Necessarily at least the described sides must fit perfectly with each other when receiving the pair of rotation.

To hold the two jaws in similar position can protrude from the rear face of the jaw of the mechanism a threaded shaft with sufficient length to pierce in its thickness the additional jaw through a hole made in its center of width and then press it a nut that will firmly fit the two jaws or the mechanism jaw may have practiced in its thickness and from its  rear face a threaded hole in which a screw is tightened which previously goes through a hole centered the jaw additional and with such action squeezes and fixes to the other.

Another option for jaw coupling additional to the jaw of the mechanism maintaining any of the two possible fixing options described is that avoiding the lateral contacts between the jaws the surfaces of contact between them are concave and convex profile or vice versa for a correct fit with each other and in this case it can be the nut or screw that fix those that avoid a possible lateral displacement of the additional jaw.

The two jaws are placed one behind the other according to any of the described options the totality is maintained of possible displacement of the jaws of the mechanism by the spindle helping to reduce the dimensions of the mechanism Adjustable for socket wrenches.

Moving on to describe the additional jaw for Adjustable mechanism for socket wrenches that can be placed on the jaw of the mechanism onwards additional jaw wrap, it can be said that it can also be subject to it by Screw pressure or other suitable system such as attraction magnetic or friction between the jaws.

In this option the additional jaw envelope It also has an elongated shape and is also divided into its length between a coupling area in the jaw of the mechanism and another area of engagement against the screw, the latter with equal features to the additional jaw option described previously. As for its coupling area in this case It is formed by a hollow prism with the open end open for the fairly fair introduction of the jaw of the mechanism and the opposite end of where the area of Additional jaw lace enclosure closed.

In this configuration if the additional jaw envelope is fixed by screwing this is done by a screw that presses against the rear wall of the jaw of the mechanism when tightened once screwed through the wall rear of the additional jaw enclosure thus located. In this case the inner side walls of the hollow prism and those of the mechanism jaw will be equally oblique opening as in the system described above, although they are done from jaw walls that remain anterior and not posterior avoiding rocking.

The characteristics of the sides of the recently described jaws can be maintained if these are held by magnetic attraction or friction between them or not, and will remain or be fitted at least during the exercise of the pair of rotation also tightening as necessary and preferably each additional jaw surrounding its jaw of the mechanism on its side so that it offers maximum possible resistance.

Finally indicate that in this case when fitting the additional jaw envelope on the jaw of the mechanism, the length of possible displacement of the latter is reduced in the thickness of the wall of the first one that is placed before the second.

As a possible feature in the jaws in any of the configurations described should indicate that they can have a stepped profile between their coupling areas and fit according to the distance between these jaws additional once placed.

Preferred examples of practical realization

Additional jaws for mechanism adjustable for socket wrenches, once fixed at the ends of adjustment on the screw of the jaws of said mechanism, allow the establishment of a new interval of measures to establish between them, greater than those of the jaws of said mechanism and which preferably start next at the largest that can be established among these. Running in pairs of identical jaws and made of suitable materials, it has each of them a series of characteristics that we pass to describe.

The description of the invention is referred to in first to an additional jaw (1) that is placed against the rear wall of the jaw of the mechanism (2) being fixed in she.

Said additional jaw (1) is shaped elongated, basically rectangular perimeter and is divided into two zones along its length that are a zone of coupling (3) to the jaw of the mechanism (2) and another area of socket (4) intended for this purpose against the screw on which act, on two opposite angles or on parallel sides thereof. To be able to adjust the additional jaw (1) over angles opposite of the screw this presents from its end to a point internal in which an angular recess (5) suitable for said angles centered on its width and if it fits only on parallel sides of the screw the fitting area (4) can be smooth from the end to an interior point where a outstanding step that will prevent a possible exit of the screw.

As for the coupling area (3) of the additional jaw (1) with the mechanism jaw (2) so the first one is fully fitted against the second one the one that tightens during the rotation laterally allowing it offer resistance throughout its width. For this purpose the sides (6) of the jaw of the mechanism (2) that define it in its thickness have oblique orientation opening from its surface of contact (7) with the additional jaw (1) being its union with it by means of a vertex or curved wall in which the vertex or curve that are drawn between the contact wall (8) of the additional jaw (1) with the previous one and the walls sides (9) that protrude open. Necessarily at least the sides (6) (9) described must fit perfectly with others upon receiving the rotation torque.

To hold the two jaws in similar position can protrude from the rear face of the jaw of the mechanism (2) a threaded shaft (10) with sufficient length to pass in its thickness the additional jaw (1) through a hole (11) practiced in its center of width and tighten subsequently to it a nut (12) that will fit firmly the two jaws (1) (2) or the mechanism jaw (2) can have a hole in its thickness and from its rear face threaded (13) in which a screw (14) is tightened than previously through an centered hole (11) the additional jaw (1) and with such action he squeezes it and fixes the other.

Another option for jaw coupling additional (1) to the jaw of the mechanism (2) keeping any of the two possible fixing options described is that avoiding lateral contacts between the jaws (1) (2) the contact surfaces between them are concave profile (15) and convex (16) or vice versa for a correct fit together be in this case the nut (12) or screw (14) that fix them that prevent a possible lateral displacement of the additional jaw  (one).

Placed the two jaws (1) (2) one behind the other according to any of the described options the possible displacement of the jaws of the mechanism (2) by the spindle helping to reduce the dimensions of the Adjustable mechanism for socket wrenches.

Turning to describe the additional jaw (1 ') for adjustable socket wrench mechanism on the jaw of the mechanism (2), hereinafter additional jaw enveloping, it can be said that it can be subject to this equally by screwing pressure or another suitable system such as magnetic attraction or friction between the jaws (1 ') (2).

In this option the additional jaw envelope (1 ') also has an elongated shape and is also divided into its length between a coupling area (17) in the jaw of the mechanism (2) and another engagement area (18) against the screw, this last with equal characteristics to the option of additional jaw (1) described above. As for its coupling area (17) in this case it is formed by a hollow prism (19) with the open end open for introduction sufficiently just from the jaw of the mechanism (2) and the opposite end of where the fitting area (18) of the additional jaw protrudes enclosure (1 ') closed.

In this configuration if the additional jaw envelope (1 ') is fixed by screwing this is done by means of a screw (20) that presses against the rear wall of the jaw of the mechanism (2) when tightened once screwed traversing the rear wall of the additional clamping jaw (1 ') so placed. In this case the inner side walls (21) of the hollow prism (19) and the side walls (22) of the mechanism jaw (2) will be equally oblique opening as in the system described above, although they do so from jaw walls (1 ') (2) that remain anterior and not later avoiding rocking.

The characteristics of the sides (21) (22) of the jaws (1 ') (2) described above can be maintained if these are held by magnetic attraction or friction between them or not, and will remain or be embedded at least during the rotation torque exercise tightening equally necessary and preferably each additional jaw wrap (1 ') to its jaw mechanism (2) on its side so that it offers The maximum possible resistance.

Finally indicate that in this case when fitting the additional jaw wrap (1 ') on the jaw of the mechanism (2), the length of possible displacement of the latter is reduced by the thickness of the wall (23) of the first jaw which It is placed before the second.

As a possible feature in the jaws in any of the configurations described should indicate that may have a stepped profile between their coupling areas (3) (17) and fitting (4) (18) according to the distance between said additional jaws (1) (1 ') once placed.
