Description

Manual guide or lock tool.

The object of the invention relates to a manual guide or lock tool including a fixed jaw and a movable jaw with a mechanism to lock in position the movable jaw with respect to the fixed jaw.

Examples of hand tools are this type, among many others, the files E0241798 and U0258997 (in an old technology) or files E0638393, E0688258 and P9501012 (in a more recent technology).

Many usual locking pliers suffer from Disadvantages for certain purposes or applications. That is why they have emerged specific tools for specific needs that they maintain unalterable common general characteristics (for example, the solution of the locking mechanism). The files E0946337, E0536652, E0638393 and U9400659, among others, are clear examples of it.

The object of the invention is a new tool guide or blocking manual characterized in that it consists of:

a) a first handle that defines a front arm fixed on which a tilting nail is pivotably mounted for pivot around a first pivot axis;

b) a second handle on which it is mounted pivotally a movable rear arm with a fixed nail associated with him to pivot the set around a second axis of pivoting which mobile rear arm, in turn, is mounted pivotally in the handle to pivot the assembly around a third pivot axis;

c) a mechanism to swing the arm movable rear around the pivot shaft and lock it in position with respect to the fixed front arm.

And in which:

a) the movable rear arm is provided with a claw with concave mooring mouth;

b) the swingarm mounted on the arm fixed front is provided with claw with concave mooring;

c) the maximum width of both arms as of the said nail is less than the minimum width of the place of job;

d) the length of the said claws mounted on the nail and movable arm is equal to or greater than the minimum length required to hold the objects to guide or block coaxially Between their mooring mouths.

With this structuring and particularities this tool is ideal when your job is required:

a) in hard-to-reach places (which have very low working width)

b) in the two-piece coaxial lock (which require large claw length)

c) in the two-piece coaxial guidance (which require large claw length).

It is indistinct for the purposes of the invention to use the tool either as a locking tool or as guide tool on which the bolts can slide, without more than varying the clamping force of the mechanism articulate.

In particular, this manual tool results effective as a tool for fastening and guiding or locking bolts in the construction sector; and more specifically in the assembly of doors with bolts in which the width of work - between the door and its frame- is reduced and the length of the bolts to guide or block (the two parts of the hinges) is relatively big.

Therefore, the manual guide or locking tool it constitutes a new invention that involves inventive activity and is susceptible of 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 a general view in schematic perspective of a manual guide or locking tool according to the invention, in open position.

Figure 2 represents a general view in schematic perspective of a manual guide or locking tool according to the invention, in closed position.

In both figures the parts of a pernio-hinge (B1), (B2) to guide or block coaxially. With greater tightening force, the parts of a pernio-hinge (B1), (B2) is block each other and, with less force to tighten the parts of a pernio-hinge (B1), (B2) are guided coaxially instead of blocking. The force of tightening the provides the articulated mechanism (4).

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 guide-lock manual, of the type of which they comprise two handles (1), (2) associated with claws or jaws, one fixed and one mobile, and with an articulated mechanism (4) bistable connection between the movable jaw and the handles (1), (2), to guide or block the mobile jaw in position with respect to The fixed jaw.

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 depicted, the handle (1) defines a front arm fixed (11) in continuity, forming handle (1) and arm (11) a single piece set.

The aforementioned fixed front arm (11) rides pivotally a tilting nail (12) capable of pivoting with respect to the arm (11) around a pivot axis (P1).

The tilting nail (12) is provided with a claw frontal (13), with concave mooring mouth (13a).

In accordance with the invention, and according to the embodiment shown, on the handle (2) it is pivotally mounted a movable rear arm (21) capable of pivoting with respect to the handle (2) around a pivot axis (P2).

The movable rear arm (21), in turn, is mounted  pivotally in the handle (1) to also pivot around a  pivot axis (P 3).

Said movable rear arm (21) is provided with a front claw (23) with concave mooring mouth (23a).

The maximum width (d) –see figure 2- both of the arms (11), (21) as of the nail (12) and its claws (13), (23) is minimum and always smaller than the minimum width of the workplace, to facilitate the work of the operator.

The length (I) of the claws (13), (23) mounted on the nail (12) and on the movable rear arm (21) is equal or greater that the minimum length required to hold the objects (B_ {1}), (B_ {2}) to guide or block coaxially between your mooring mouths (13a), (23a).

In guiding or locking position of the tool –see figure 2- the claws (13), (23) are inclined a certain angle (?) with respect to the handles (1), (2).

For the embodiment represented, said angle (?) of inclination is, (?? 35 °).

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.
