Description

The present invention relates to a device for

  swiveling jaws adaptable to any support for

  stable way of tightening, assembling or

  in the position of pieces of shapes and sizes

  conches. We know that tools with jaws or jaws

  used for clamping or assembling parts are gen-

  usually consist of two jaws mounted on a support member serving as a guide, a piece along which can slide at least one of these jaws so as to adjust their spacing depending on the importance of the piece to be clamped or parts to be assembled and / or held in position Numerous devices such as notches, ratchets, screws or the like associated or not with springs are provided to maintain the relative position of the jaws and / or to exert

  pressure on the part (s) to be clamped or assembled.

  One of the characteristics common to all these devices lies in the fact that the jaws or jaws of identical or complementary shapes face each other and that they can not be oriented in space to occupy, one relative to the other This is all the more understandable if the jaws do not face and are therefore shifted, the forces applied to the part or parts to be clamped at points lying in different planes or following different orientations, create a couple that has the effect of tilting the part or parts to

  tightening, which hampers the stability of the clamping system.

  their, this kind of tightening is difficult to resist when the enclosed part (s) are subjected to constraints

  or external shocks (hammer blow for example).

  Finally, the known devices are manufactured with dimensions, shapes, sizes that can not

  be modified according to the intended use.

  Depending on the work to be done and the importance of the parts to be clamped or assembled, tools will have to be used.

  different in size and strength.

  However, the present invention obviates these drawbacks.

  and a device for gripping and / or assembling and maintaining in stable position one or more parts in an easy manner regardless of the relative position thereof or their shape This device is

  characterized by the fact that it is essentially

  killed by the combination of two separate pieces interchanging

  gables in the form of jaws each equipped with a means

  putting his editing and translation with possibility

  orientation and its locking in position on a sup-

  port of any shape and / or section and a third

  second piece also interchangeable said abutment piece or support and provided with a means for mounting and translation with possibility of orientation and

  its locking in position on the same support.

  According to other characteristics: the jaws and the stop or support piece

  may be of various shapes and sizes in proportion

  with the shapes and dimensions of the element or elements to be clamped; a system to exert pressure

  continuous operation is provided on at least one of the jaws during

  that a coin is inserted between them; an auxiliary device is provided to act directly on the one hand, on the translation of at least one of the jaws and, on the other hand, on the system intended to exert, in the working position, a continuous pressure on

below it.

  According to an advantageous embodiment:

  the jaws are provided with necklaces or

  in accordance with the invention; lad figura e N is a corresponding perspective view showing the possibility of orientation of

  different elements of the device according to the

  vention; and FIG. 3 is an elevational view of two devices according to the invention coupled to the same support.

  with a unique control system.

  Referring to these drawings, the device according to the invention essentially comprises: two jaws 1-la each provided with a means allowing their mounting, their translation, with the possibility of orientation, and their locking in position on any support such as that rod 2 of shape, section and any size This rod 2, may optionally be inserted into a base E Such a means can be, for example,

  a clamping collar comprising, in the usual manner

  for example a butterfly nut; a piece 4 called abutment piece or support affecting, for example, the shape of a rod This piece is also provided with a means for mounting and translation with possibility of orientation on the same support 2 This means 5 can be of the same type as the one who

  is used on jaws 1-la or of a different type.

  In this simplest embodiment of the invention, it is possible, by adjusting the spacing between the jaws, to grip one or more pieces

  (such as P) without worrying about having, in order to avoid

  couple fetish, to bring the jaws rigorously in front

one from the other.

  Indeed, it is sufficient, to neutralize this torque, to bring the abutment piece or support (4) against a fixed surface S belonging or not to the assembly which is or could be part or parts This possibility provided thanks to the device according to the invention is all the more interesting that this or these pieces to grip are difficult to access and whose grip does not

  can therefore be envisaged that between jaws diver-

  oriented and supported by a support 2, having a shape and dimensions that do not interfere with such access or

such disposition of the jaws.

  Advantageously, the simplest device above is associated with a system for

  increase jaw clamping efficiency and stability

  the impact of this tightening, the system itself

:: 2516840

to be easily operated.

  The appended figures illustrate an example of

  possible embodiment of such a system.

  According to this embodiment, a spring 7 is provided between one of the jaws (la) and a ring 6 also provided with its means (for example butterfly nut clamp 3) allowing its assembly and its

  translation with possibility of orientation on the rod 2.

  It is easy to imagine that by exercising, by some means,

  conque, a compressive force of said spring in the direction of the arrow F, by acting on the jaw, one deviates thereby said jaw of the jaw l to allow to insert between them the piece to be clamped or parts to assemble Of course the jaw 1 is previously brought and blocked on the rod 2, in a position such that said spacing, after compression of the spring, can allow said insertion -Once this one achieved, it is sufficient to release the compressive stress of the spring

  for the jaw to come to bear on the said -

  parts with a corresponding force exerted by the spring, this force being all the more important as the spring

is compressed.

  The action on the spring 7 in the direction of the arrow F can be done manually by acting directly on the jaw 1a and maintaining it in the desired position with the help or not of a mechanical locking means as long as necessary It is also possible to act by means of an auxiliary system. Such an auxiliary system must be designed so as, on the one hand, to be able to slide said jaw 1a along the rod 2 by compressing the spring 7 and, on the other hand , being able to maintain said spring in compression (thus the jaws 1 and the apart) without other interventions as long as the parts or parts

  involved were not inserted between these jaws.

  The embodiment illustrated in the drawings

  is a non-limiting example of such an ancillary system.

  It comprises a control stirrup 8 (provided with a control handle 9) mounted articulated at 6a on the ring 6 This stirrup cooperates with two parts such as 12 that play the role of levers and which are connected so articulated at one of their ends, at 13, to the jaw 1a and at the other end to said yoke by means of a lug 10 The fastener 13 is located in the median position with respect to the housing of the jaw the pin 2 The pin 10 is carried by each of the branches of the stirrup 8 and cooperates with

  a window or slide 11 made on each piece 12.

  It is easily seen that by operating the handle in the direction of F 1 i the ring 6 being immobilized in position, the jaw is biased down (arrow F) and the spring 7 is compressed following the relative assembly of the system joints it is easy to understand that this handle can occupy a low equilibrium position so that, without further intervention, said jaw remains lowered and said spring is compressed as long as

the desire.

  Wanting to return the handle 9 to its initial starting position involves the breaking of this balance The jaw is then pushed up (arrow F 2) to find the starting position as shown in Figure 1 However, if one or several pieces are inserted between the jaws 1 and la, they are in turn subjected to the stress exerted by the spring 7 which will remain partially compressed due to the thickness of the said inserted part (s) Even if this thickness came to reduce under the effect of tightening, or to vary under the effect of any external stresses, it is easy to see that the clamping will be maintained because the spring is not in any

embarrassed way in its expansion.

  FIG. 3 shows two pairs of jaws mounted in the same manner as that just described and that can be actuated by a single

control handle.

  The examination of this figure shows that the opening of the pair of jaws 11a and the compression of the spring 7 corresponds to the closing of the pair of jaws lb-1c and to the expansion of the spring 7a. In other words, it is possible to grip independently of different parts by means

  of a single device and with an operation of the easiest.

  Of course, the abutment piece or support 4 can be used for both sets in the direction of the couples to cancel or

  well it will be expected a piece 4 for each pair of m Achoires.

  The device of the invention can be easily produced by means of removable and interchangeable parts that are independent of one another and can be mounted on

  supports of any shape and size.

  It will also be noted that such a device has the advantage of an easy maneuver, in particular the clamping can be

  obtained by the action of a single hand of the operator.

  It goes without saying that the present invention has been described and illustrated only in a purely explanatory and non-limiting manner and that any useful modification may be

  to be brought without leaving the frame.
