Definitions
- One-handed adjustable clamp is
- the present invention relates to an adjustable clamp manipulable with one hand, of the type described in the preamble of claim 1.
- EP-A-218 760 describes a clamp of this type, in which the mutual guidance of the branches during the approach phase of the clamp is obtained by means of an articulated arm which crosses the space situated between the two handles.
- the term “approach phase” should be understood to mean the step of using the forceps in which, in the absence of contact between the two jaws with an object to be grasped, forces are exerted on the handles in suitable directions tending to bring the bit.
- Such an articulated arm has the main disadvantages of constituting a risk of pinching for the fingers of users, of being exposed to shocks and dirt, and of suppressing any freedom of angular movement of the branches relative to one another.
- the object of the invention is to provide an adjustable gripper which can be manipulated with one hand, of relatively simple construction, which ensures improved comfort, flexibility and safety of use while allowing excellent control of the approach phase.
- the invention relates to an adjustable clamp of the aforementioned type, characterized by the characterizing part of claim 1.
- the adjustable clamp according to the invention may include one of the characteristics described in claims 2 to 22, taken in isolation or according to all their technically possible combinations. Examples of embodiments of the invention are now described with reference to the appended drawings, in which:
- FIG. 1 is a schematic view of an adjustable clamp according to the invention, in the rest position and in approach phase;
- Figure 2 shows on a larger scale a detail of Figure 1;
- FIG. 3 is a similar view of the clamp of Figure 1, during clamping of an object
- FIG. 6 is a similar view of a second embodiment of the clamp according to the invention.
- the adjustable clamp 1 shown in FIG. 1 consists of two branches 2 and 3, an articulation member or finger 4, a support element 5 and an opening spring 6.
- the branch 2 or movable branch is constituted by a solid metal part which defines, from front to rear, that is to say from left to right considering FIG. 1, a movable jaw 7, a intermediate articulation region 8, a rear support region 9 and a handle 10. On the latter can be attached a grip sheath 11, as shown.
- the jaw 7 has an upper toothed face 12 for gripping an object 13.
- the face 12 has end regions 12A, 12B, substantially planar and coplanar, separated by a region 12C in a very open V.
- the support region 9 has a convex lower surface 14 in the form of an arc of a circle whose center 0 is a virtual point situated clearly outside the contours of the tool, above the latter.
- the upper surface 15 of the 2ranche 2 in the same region, is rectilinear and close to the cord which underlies the arc of a circle 14.
- the handle 10 is curved, with its convexity facing upwards.
- the branch 3 or fixed branch, defines from front to back a fixed jaw 16, attached to the main part of the branch by means of rivets, an intermediate articulation region 17, a rear support region 18 and a handle 19 coated with a sheath 20.
- the jaw 16 has on its underside a toothing 21 with two roughly flat and coplanar zones 21A, 21B framing a zone 21 C in a very open V. As shown in the drawing, in the V-shaped zones of the jaws, only the rear part of the zone 12C and the front part of the zone 21C are toothed.
- Region 17 has a generally arcuate shape and center 0. It is delimited by smooth lower and upper surfaces 22 and 23 in the form of arcs of a circle with center 0, and comprises an arcuate light 24. This is delimited by a smooth upper surface 25 and by a lower surface 26 in the form of a toothed rack. Each of the surfaces 22 to 25 as well as the mean line of the surface 26 are arcs of a circle with center 0.
- the jaws 7 and 16 are entirely outside the circle with the largest radius 22.
- the articulation member 4 ( Figure 2) is a piece of elongated shape freely articulated approximately at mid-length by a pivot 27 on the region 8 of the branch 2. This piece comprises
- the fixed branch 3 also comprises a blind housing 31 open upwards in which a slide 32 is received. The latter is pushed upwards by a spring 33, which is here a helical compression spring, to a position of rest as shown, in which the slide is supported on a stop (not shown) secured to the branch 3.
- the slide 32 has at its upper part a support projection 34 for the support surface 14 of the branch 2 .
- the movable arm 2 is shown in thin lines in the rest position and in thicker lines during approach.
- the point 34 is fixed relative to the branch 3.
- a sudden force exerted on the handles can cause a slight compression of the spring 33, but the latter immediately resumes its length. origin.
- the point 34 is therefore always fixed or substantially fixed with respect to the branch 3.
- the normals NI and N2 at the contact points 28, 34 of the guide 25 and support 14 surfaces form a V whose point is directed upwards, that is to say on the side opposite the jaws.
- This V may have an angle slightly less than 90 ° as shown or, alternatively, an angle substantially equal to 90 °.
- the point of contact of the movable jaw 7 with this object then defines a center of rotation, and the pursuit of the effort of bringing together the two handles causes the branch 2 to tilt around this center.
- the clamp thus described has a relatively simple construction and provides great smoothness and precision during the approach phase.
- the generally concave shape of the intermediate region of the tool obtained by means of surfaces 23 and 15, makes it possible to slide the front part of the pliers into locations which are difficult to access, for example behind a pipe.
- the arcuate shape of the lower surface 22 gives the tool a particularly tapered general profile.
- the light 24 can easily include a rear part whose orientation approximates that of the movable handle 10. This reduces the effort to be exerted on the handles to start the approach , compared to the usual case where the light is rectilinear as in the aforementioned EP-A-218 760. Furthermore, no member extends between the rear parts of the two branches, which protects the user's fingers.
- a projecting stud 37 is provided on the branch 2, at the rear of the jaw 7, a projecting stud 37. From a certain degree of opening of the handles, this stud abuts on the surface 22, which limits the opening of the handles.
- the light 24 is rectilinear, as is the lower surface 22.
- the surfaces 22, 25 and the mean line of the surface 26 are mutually parallel;
- the upper surface 23 is substantially rectilinear, with an orientation which diverges backwards with respect to that of the light 24;
- the branch 3 has opposite this surface 23 a lower surface 23A substantially parallel to the latter;
- the bearing surface 14 is straight and substantially parallel to the upper surface 15; -
- This surface 14 is supported, in rolling and / or sliding, on a roller 38 carried by the upper end of the slide 32; and
- the distal zone of the handle 19, adjacent to the support region 18, has a recess 39. Due to the recess 39, the lower surface of the handle 19 closest to the jaws defines two support zones, proximal 40 and distal 41, the respective mean lines 42 and 43 of which form a certain angle between them.
- the line 42 makes an angle xl of between 45 and 55 ° and preferably 50 °
- the line 43 makes an angle x2 significantly larger than xl, on the order of 75 to 90 °.
- the handle 10 furthest from the jaws has a convex upper surface, which defines a proximal zone 45 and a distal zone 46, the respective mean lines 47 and 48 of which form a certain angle.
- the line 48 forms an angle yl of 45 to 55 ° and preferably 50 °, while the line 47 forms a greater angle y2, of the order of 75 to 90 °.
- the pair of surfaces 41 and 45 facilitates the approach phase of the clamp, described above, thanks to the orientation of the force ⁇ e approximation FI which is exerted on them.
- the pair of surfaces 40 and 46 makes it easier to clamp the gripped object, thanks to the orientation of the force F2 exerted on them.
- the light 24 is arcuate, that is to say that its surface 25 and the mean line of its surface 26 are arcs of a circle with center 0;
- the bearing surface 14 is also an arc, but its center 0 'is distinct from the point
- FIG. 6 operates in a similar manner to that which has been described above, but with a structure modified in the following manner with respect to the embodiment of FIGS. 1 to 3.
- the rack 26 is formed on the upper surface 23 of the intermediate region 17 of the fixed branch, and the jaw 7 has, at the rear and at the bottom, a spout 50 directed towards the rear.
- the rack 26 is extended rearwards by a smooth bearing surface 114.
- the slide 32 is carried by the movable branch 2, facing the surface 114, and is biased downward, to a predetermined limit position by a stop not shown, by the spring 33.
- the points 35 and 36 for hooking the opening spring 6 are located respectively at the rear end of the handle 19 and slightly behind the slide 32.
- the finger 104 is articulated, by means of the pivot 27, on the branch 2 so that the teeth 29 are at a distance from the spout 50 greater than the thickness of the part 17, this under the action of a spring 51 which keeps the front surface 30 of the finger in contact with the rear face of the intermediate part 17 of the fixed branch 3.
- the spring 6 maintains the two jaws in the maximum spacing position, this position being determined by appropriate stops (not shown) of the two branches.
- the branch 2 pivots slightly clockwise around the point of contact between the slide 32 and the surface 114, which moves the axis 27 away from the rack 26 and brings the spout 50 to the surface contact 22.
- the branch 2 first pivots around its point of contact with the object 13, compressing the spring 33, until the teeth 29 of the finger 104 are blocked in the rack 26. Then this engagement defines a new center of rotation of the branch 2, which allows to tighten the object 13 as before. Thanks to the action of the spring 51, the teeth 29 are released from the rack 26 when the handles of the clamp are released.
