Abstract

Adjustable clamp, for coaxial clamping of cylindrical parts; characterized because it consists of: A) a fixed handle (1) on which a fixed arm (11) is mounted which, in turn, also mounts a fixed claw (12); B) a movable handle (2) that is articulated in (p2) to an intermediate arm (21) which, in turn, is articulated in (p3) to the fixed handle (1) and on which also mounts a tilting claw (22), capable of rotating around an axis of rotation (p4).

Description

Adjustable pliers, for coaxial clamping of parts cylindrical

The object of the invention relates to a hand tool, particularly to an adjustable pliers which include a fixed jaw and a mobile jaw with a mechanism that regulates its opening and keeps its claws approximate being able to be locked in a selected position holding coaxially cylindrical parts such as hinges or door or window bolts.

Adjustable tongs used offer no solution For all the problems. That is why we see tools emerge  specific for specific needs that remain unchanged common general characteristics (for example, the solution of locking mechanism). The files E0946337, E0536652, E0638393 and U9400659, among others, are clear examples of this.

There are adjustable tongs to align parts cylindrical, with fork-shaped jaws, which are characterized by the fact that the plane of symmetry it contains the tool is positioned perpendicular to the axis of coaxiality of the fastened parts, which makes its use absolutely impossible for fasten a bolt between a door and its frame.

The object of the present invention is a new Manual tool of this type that:

- has an oblique or angled angular arrangement of the jaws with respect to the handles, as a pistol;

- plane of symmetry of the tool contains the coaxial axis in such a way that the thickness of the jaws, allowing access to narrow places and giving the tool the most convenient ergonomics; Y

- Its main tightening effort serves to maintain alignment without preventing coaxial slippage or relative displacement of the cylindrical pieces with each other.

The present invention consists of:

a) a fixed arm on which, in turn, rides also one or more pieces forming a fixed claw, constituting a fixed jaw that is firmly attached to a fixed control;

b) a movable arm on which one or more pieces forming a tilting claw, which will always be positioned parallel to the fixed claw, constituting a movable jaw that remains articulated on said fixed handle and also on a handle mobile;

c) a regulation mechanism to adjust the position of the jaws and allow to coaxially hold the objects;

and in which:

- the claws of both jaws have a concave longitudinal configuration of a "U" or "V" section arranged in a facing position so that they can hold each other, with the inside of their wings, cylindrical objects of a variety of sizes.
ños - the claws are mounted on the respective arms longitudinally offset from each other by a distance (d), so that they form a step - the maximum width of the jaws (a) is less than the minimum width of the workplace,

- the length (I) of the claws is equal or greater that the minimum length required to hold the objects to be guided, tighten or block coaxially arranged in their mouths concave longitudinal

Therefore, the hand tool constitutes a new invention that involves inventive activity and is susceptible to industrial application

To better understand the purpose of this invention, a preferred form of practical realization, susceptible to accessory changes that do not distort its foundation.

Figure 1 represents an overview Schematic elevation of a hand tool according to the invention.

Figure 2 represents a partial front view of the hand tool corresponding to Figure 1 to appreciate the configuration of the claws (12),
(22).

An example of practical, non-limiting embodiment of the present invention. I dont know discarded at all other embodiments in which introduce accessory changes that do not distort its foundation; by On the contrary, the present invention also covers all its variants.

The object of the invention is a new tool Adjustable pliers type manual.

This mechanism is not described in more detail. articulated (4) for not being the main object of the invention and because It is part of the current state of the art: it is represented in detail in, for example, Patent EP0638393 (Figure 1) and in Utility Model U0258997 (figure 1).

In accordance with the invention, and according to the embodiment shown, the handle (1) defines or mounts a fixed arm (11) in continuity, forming handle (1) and arm (11) a set rigid.

In the embodiment shown, the handle (1) and the fixed arm (11) are two pieces solidly joined together, by example, with rivets (R1), (R2).

Said fixed arm (11) mounts a fixed claw (12). In the embodiment shown, fixed claw (12) and fixed arm (11) are solidly linked together, for example, with rivets (R3), (R4).

In accordance with the invention, and according to the represented embodiment, in the handle (2) an arm is articulated intermediate (21) capable of rotating with respect to the handle (2) around a axis of rotation (P2).

The intermediate arm (21), in turn, is mounted pivotally on the handle (1) to also rotate with respect to it around an axis of rotation (P3).

Said intermediate arm (21) is provided with a tilting claw (22) capable of rotating around an axis of turn (P4).

Both fixed (12) and tilting (22) claws are of elongated configuration and define, or are provided with, mouths concave longitudinal (12a), (22a).

Preferably, according to the embodiment represented, these claws (12), (22) are bodies of a piece of "U" general section and mooring mouths are defined making the ends of its wings (12a), (22a) chamfered - see Figure 2 -.

Preferably, the claws (12), (22) are mounted on the respective arms (11), (21) longitudinally staggered each other a distance (d) - see figure 1 -.
Particularly, the claw (12) of the fixed arm (1) is frontally tucked in said distance (d) with respect to the tilting claw (22) of the movable arm, so that one end of the claw serves as support for the piece and the another limit stop that helps the
centered.

The tool is designed in such a way that
- see figure 1 - the claws (12), (22) are arranged almost orthogonally with respect to the handles (1), (2).

It is imperative that the maximum width (a) - see Figure 2 - both arms (11), (21) and claws (12), (22) is always smaller than the minimum width of the workplace to be able to position the tool.

The length (I) of the claws (12), (22) mounted in the arms (11), (21) is equal to or greater than the minimum length required to hold the objects to guide or block coaxially between their mooring mouths (12a), (22a).

The materials, dimensions, may vary  proportions and, in general, those other accessory details or side effects that do not alter, change or modify the essentiality proposal.

The terms in which this report is written they are true and faithful reflection of the object described, being taken in its broadest sense and never in a limiting way.
