Definitions
- This invention refers to a movable head, which in combination with a fixed head and a guide, makes up a vise or handscrew able to clamp one object to another.
- a vise of this type is shown, for example, in the Spanish utility model with application number U9900362, or in the utility model with application number U200202066.
- the figures described show how the body of the head (1) incorporates a transverse orifice (2) in correspondence with one of its ends.
- This orifice serves to allow said body or movable head (1) to move along a guide not shown in the drawings, whose cross section coincides in shape and dimensions with that of the orifice (2).
- the head (1) is locked onto this guide because of the head's tendency to tilt laterally when its pressure element (3) is acted on, locking that may be favored by the existence of a brake (4) on the head (1), next to the orifice (2).
- the brake (4) is equipped with a toothed front that acts on the edge of the guide. In any case, the pressure element (3) can move parallel to said guide when a manual lever (5) is acted on, all in a conventional manner.
- a second orifice parallel to the first one formed by two coaxial sections.
- One section (6) the one closest to the pressure element (3), has a smooth surface, and the other (7) has an inner thread on which a shaft moves.
- the shaft has two sections: a section (8) opposing the pressure element (3), which screws onto the aforementioned section (7) of the orifice on the body (1), and a second section (9), whose diameter is considerably smaller and whose thread direction is the opposite of the one on section (8), which in turn screws into a bushing (10).
- This bushing has a threaded inner surface in correspondence with section (9), and its outer surface slides on the unthreaded section (6) of the aforementioned orifice, while its free end receives the aforementioned pressure element (3) by means of a rivet or any other means.
- Said bushing (10) can only move axially in its housing as it is related to the body (1) of the movable head with the collaboration of a pin or similar device (11).

Abstract
Description
- The traveling movement of the pressure element, to definitively close the vise on the items to be secured, is relatively slow because of the number of turns that must be applied to the screw in order to make the latter advance. If a broad scope of action is desired for this pressure element, the screw must also be of a considerable length, which has a negative impact on the vise's size.
- The aforementioned screw is usually in the open, so its thread is constantly exposed to external agents. While it is easy to lubricate, it is very difficult to maintain this lubrication over time, as the lubricant is just as easily lost. There is also a risk that dirt may adhere to the lubricant and be carried into the movable head's threaded orifice, possibly damaging the thread of said orifice or the thread of the screw itself.
Claims (5)
- Movable head for vises, of the type that incorporates an elongated body (1) on one of whose ends there is a transverse orifice (2) for the movement of said body (1) along a guide, as it travels to quickly approach the fixed head in which said guide ends, and on whose other end there is a second orifice parallel to the first one, in which a means of travel parallel to said guide moves for a pressure element (3), by acting on them with the collaboration of a manual lever (5); this movable head for vises is characterized in that the aforementioned orifice on the end of the body (1) opposing the guide incorporates two sections (6) and (7), one smooth and the other threaded, so that an element (10-18) slides on the smooth section (6); the pressure element (3) is solidly joined to the outer end of this element (10-18), which is related to a shaft (8-14) by means of a thread; this shaft (8-14) has two opposing threads, so that it relates to said element through one of them, while it relates to the threaded section (7) of the orifice on the body (1) of the head with the other one; this shaft (8-14) receives the mechanism's manual lever (5) diametrically through its free end.
- Movable head for vises, according to the first claim, characterized in that the shaft (8) incorporates two coaxial sections with different diameters: section (8) with a larger diameter, through which it relates to the threaded section (7) of the orifice on the body (1) of the head, and a second section (9) with a considerably smaller diameter, threaded in the opposite direction from the former, which moves in the hollow interior of the element (10) supporting pressure element (3); said element (10) is made up of a bushing with a smooth outer surface and a threaded inner surface.
- Movable head for vises, according to the first claim, characterized in that the shaft (14) is made up of a bushing with an outer thread (16), which is complementary to the threaded section (7) of the orifice on the body (1) of the head, and with an inner thread (15) through which it receives the threaded end (17) of the element (18) to which the pressure element (3) is solidly joined; this element (18) is made up of an arm with a smooth outer surface that moves in the also smooth section (6) of the hole on the body (1) of the head and which extends axially into the aforementioned threaded section (17).
- Movable head for vises, according to previous claims, characterized in that the sliding element (10-18) to which the pressure element (3) is solidly joined is related to the smooth section (6) of the orifice on the body (1) of the head through a pin (11) which prevents it from turning while allowing longitudinal movement.
- Movable head for vises, according to previous claims, characterized in that on the wall of the orifice (6-7) on the body (1) of the head there is a lubricator (12) providing access to the chamber (13-13') defined within said orifice by the element (10), (18) and by the shaft (8-9), (14).
