Description

Buckle for securing end portions of strapping together and its use

The present invention relates to a loop for attaching a first end portion of a strap to a second end portion of a strap, a mounting sub-assembly and an assembly comprising such a loop, and an associated method of use.

Among the various means available for attaching an object to a support such as a post, it is known to use one or more strips. A strip is a deformable strip of metal, which surrounds the support and whose end portions are fixed to a loop. Depending on the application, the objects to be fixed are, for example, a signaling panel or a connection box. Each strap is placed in mechanical tension around the support, the size and the tension of each strap, as well as the type of buckle, being chosen according to the nature of the objects to be fixed.

The loop generally includes flaps, to secure the sliding of the strap after having stretched it around the support. However, tensioning the strap requires the use of a specialized tool, such as a hand-cranked or lever-operated strapping machine, or even a portable electric tool, to secure the end portions to the buckle while keeping the strap taut. . However, such a specialized tool is cumbersome and expensive to purchase.

It is to these problems that the invention more particularly intends to remedy, by proposing a fastening loop for strapping which is easier to put in place and practical to use.

To this end, the invention relates to a loop for attaching a first end portion of strapping to a second end portion of strapping, the loop comprising:

• an attachment portion, having an attachment edge around which the first end portion is intended to be hooked;
• a locking portion, having a locking edge around which the second end portion is intended to be hooked, the locking edge being arranged parallel to and facing the attachment edge, so that the attachment portion and the locking form between them a main orifice of the buckle, delimited by the attachment edge and the locking edge;
• the buckle also includes a segment, which connects the attachment portion to the locking portion bordering the main orifice.

According to the invention, the loop is plastically deformable between:

• a mounting configuration, in which the locking portion is oriented, in a deployed orientation with respect to the fastening portion, around a transverse axis of the buckle which is parallel to the fastening edge, so that the edge of latch and the fastening edge are within mounting distance of each other, and
• a closure configuration, in which the locking portion is oriented in a folded orientation with respect to the fastening portion, around the transverse axis, so that the locking edge and the fastening edge are at a distance d hang from each other, which is less than the mounting distance.

Thanks to the invention, it is not necessary to resort to a specialized tool to fix the first end portion to the second end portion, which is practical and economical. The buckle is particularly easy to put in place: for example, initially the end portions of the strip are fixed by hand to the attachment and locking portions, without having to be tensioned other than by hand, possibly by using a generic tool such as pliers. Secondly, the locking portion is folded down so as to bring the end portions closer together. If these end portions belong to the same strip that surrounds a support, this can advantageously allow the strip to be stretched around this support, by hand with a generic tool such as pliers or a hammer. Fitting the loop is therefore quick and easy.

According to advantageous but not obligatory aspects of the invention, such a loop can incorporate one or more of the following characteristics taken separately or according to any technically admissible combination:

• advantageously:
  • the locking portion comprises an end edge, which is parallel and opposite to the locking edge,
  • the attachment portion extends along an attachment plane parallel to the transverse axis,
  • in the mounting configuration, the locking edge and the end edge are located on either side of the attachment plane, and
  • in the closed configuration, the locking edge and the end edge are each closer to the attachment plane than in the mounting configuration.
• The loop includes a junction, via which the segment is attached to the locking portion, the junction being arranged between the locking edge and the end edge.
• The junction is arranged closer to the locking edge than to the extreme edge.
• The locking edge is serrated and/or the fastening edge is serrated.
• The attachment portion, the locking portion and the segment are formed in one piece by a cut metal sheet.
• The segment forms two parallel blades, each connecting the attachment portion to the locking portion, and bordering the main orifice on either side.

The invention also relates to a mounting sub-assembly, comprising:

• the loop as previously defined, and
• a strip, comprising the first end portion and the second end portion, which is opposed to the first end portion.

Advantageously:

• the buckle has an inner side and an opposite outer side, which each extend along the attachment portion, the segment and the locking portion, the outer side being recessed when the buckle is in the assembly configuration;
• to be attached to the attachment portion, the first end portion comprises:
  • a first intermediate part, which extends along the attachment portion on the outer side, and
  • a first end part, which extends along the attachment portion on the internal side, the first end part being connected to the first intermediate part through the main orifice;
• to be hooked to the locking portion, the second end portion comprises:
  • a second intermediate part, which extends along the inner side locking portion, and
  • a second end part, which extends along the locking portion on the outer side, the second end part being connected to the second intermediate part through the main orifice.

The invention also relates to a fixing assembly comprising a support, such as a post, and the mounting sub-assembly as defined previously, in which:

• the strip surrounds the support; And
• the first end portion is attached to the attachment portion and the second end portion is attached to the locking portion while the buckle is in the locking configuration, such that the buckle exerts a tensile force on the first end portion, relative to the second end portion, thus tightening the strip around the support.

According to another aspect, the invention relates to the use of a buckle as defined above, the use comprising a pivoting actuation of the locking portion with respect to the attachment portion around a parallel axis of rotation to the transverse axis, from the extended orientation to the folded orientation, to change the buckle from the mounting configuration to the closing configuration.

Advantageously:

• the use further comprises, prior to the pivoting actuation:
  • an installation of a strip, comprising the first end portion and the second end portion, around a support, then
  • hooking of the first end portion on the attachment portion and of the second end portion on the locking portion; And
• once the pivoting actuation has been performed, the loop exerts a tensile force on the second end portion, relative to the first end portion, thus tightening the strip around the support.

The invention will be better understood, and other advantages thereof will appear more clearly in the light of the following description, of two embodiments of a buckle for fixing a first end portion of a strip and a second end portion of a strip; of a mounting sub-assembly comprising a strip and such a loop, of an assembly comprising a post and such a mounting sub-assembly, and of a method of use in accordance with its principle, given solely by way of example and made with reference to the accompanying drawings, in which:

A fixing assembly 2 is shown in the . The fixing assembly 2 comprises a support 4, and a mounting sub-assembly 6 comprising a strip 60 and a loop 100, in accordance with a first embodiment of the invention. The assembly sub-assembly 6 makes it possible to fix an object 8 to the support 4. The object 8 is a sign in the example illustrated. As a variant, the object 8 is an anchoring element. Depending on the size and/or the weight of the object 8, two mounting subassemblies 6, or even more, are used to fix the object 8 to the support 4.

The support 4 is partially represented on the . The portion shown of the support 4 has an elongated shape extending along an axis A4. The support 4 is here is here a wooden post, cylindrical of circular section. As a variant, the support is made of metal or concrete. The axis A4 is shown vertical here. Alternatively the axis A4 is inclined or horizontal. This description is made in relation to the orientation of the various elements as represented in the figures, and does not prejudge the orientation of these elements in reality.

The strip 60 is a metal strip, that is to say a strip made of metal, preferably steel. In general, the strip 60 is plastically deformable, and can be manipulated by hand to be put in place and stretched around the support 4. The strip 60 is also bendable by hand, that is to say that an operator can mark a fold by hand, or even with a tool such as pliers. Once the fold has been marked, the strip 60 is plastically deformed and retains its folded shape. Typically, the strip 60 used in the context of the present invention is sized to have a breaking strength of between 50 daN – deca-Newton – and 300 daN, has a thickness of between 0.2 mm and 1.5 mm, and a width between 10 mm and 50 mm.

The strip 60 includes a first end portion 62 and a second end portion 64, which is opposite the first end portion 62.

The loop 100 is designed to fix the first end portion 62 to the second end portion 64. In the example illustrated, the first end portion 62 to the second end portion 64 belong to the same strip 60. In a variant not shown, the first portion end 62 and the second end portion 64 each belong to a respective strip 60.

The buckle 100 comprises an attachment portion 120, around which the first end portion 62 is hooked, and a locking portion 140, around which the second end portion 64 is hooked.

The attachment portion 120 and the locking portion 140 are connected to each other by a segment 160. In the example illustrated, the segment 160 forms two parallel blades 162, which each connect the attachment portion 120 to the locking portion 140. The blades 162, the attachment portion 120 and the locking portion 140 delimit a main orifice 180 of the buckle 100, the blades 162 bordering the central orifice 180 on either side.

The attachment portion 120, the locking portion 140 and the segment 160 are advantageously formed in one piece by a cut metal sheet. Thus the loop 100 is made of a metal sheet, for example steel, having for example a thickness of between 0.5 mm and 2 mm.

On the , the loop 100 is shown assembled to the strip 60 in a closed configuration, in which the locking portion 140 is oriented, relative to the attachment portion 120, in a so-called folded orientation. The buckle 100 has an inner side 102, which is oriented towards the support 4, and an outer side 104, opposite the inner side 102. The inner side 102 and the outer side 104 each extend along the attachment portion 120, segment 160 and locking portion 140.

The attachment portion 120 extends along an attachment plane P120, while the locking portion 140 extends along a locking plane P140. In folded orientation, the attachment plane P120 and the locking plane P140 are each tangent, to within plus or minus 10°, to an envelope of the support 4. In other words, the attachment plane P120 and the locking plane P140 are parallel to each other to within plus or minus 20°. In the example of Figure 1, the P120 attachment and P140 locking planes are parallel to each other.

On the , the buckle 100 is shown alone, before its attachment to the first end portion 62 and to the second end portion 64, in a so-called mounting configuration, in which the locking plane P140 is raised relative to the attachment plane P120, the outer side 104 forming a hollow. As explained below, the transition from the mounting configuration to the closing configuration is done, under the action of an operator, by plastic deformation of the segment 160. In other words, the loop 100 is plastically deformable between its configuration of fastener and its closure configuration.

In the assembly configuration, the locking portion 140 is oriented in a deployed orientation with respect to the attachment portion 120, and the attachment P120 and locking P140 planes intersect along a transverse axis A100 of the buckle 100. The P120 attachment plane and P140 locking plane are therefore parallel to the transverse axis A100. In this deployed orientation, the locking portion 140 is more inclined relative to the attachment portion 120 than in the folded configuration.

The attachment portion 120 has an attachment edge 122 around which the first end portion 62 is intended to be hooked, while the locking portion 140 has a locking edge 142 around which the second end portion 64 is intended to be attached. hooked. The locking edge 142 is arranged parallel to and facing the attachment edge 122 on either side of the main orifice 180. In other words, the attachment portion 120 and the locking portion 140 form between them the main orifice 180 of the buckle 100, the main orifice 180 being delimited by the attachment edge 122 and the locking edge 142.

The attachment edge 122 advantageously has a notch 124, which makes it possible to center the first end portion 62 during its attachment to the attachment edge 122, so as to prevent the translational movements of the first end portion 62 with respect to the attachment portion 120 along the transverse axis A100. Optionally, the locking edge 142 is serrated, to reduce the risk of the second end portion 64 slipping relative to the locking portion 140 when attaching a strip 60 to the loop 100 around a support 4, as explained later.

The passage from the external side 104 to the internal side 102 through any orifice of the loop 100, for example the main orifice 180, defines an incoming direction F180 of this orifice, shown by an arrow in the figures. An outgoing direction F181 is also defined as being an opposite direction to the incoming direction F180.

The locking portion 140 also includes an end edge 144, which is parallel and opposite the locking edge 142. In the assembly configuration, while the locking portion 140 is in the deployed position, the locking edge 142 and the extreme edge are located on either side of the attachment plane P120, while the locking edge 142 and the attachment edge 122 are separated from each other by a mounting distance L1.

In the assembly configuration, each blade 162 has a curved portion which is connected to the locking portion 140 via a junction 164, which is arranged between the locking edge 142 and the extremal edge 144.

An example of use of the loop 100 is now described with the aid of FIGS. 3 to 6.

On the , the loop 100 is in the assembly configuration, and the first end portion 62 is hooked to the attachment portion 120, by crossing the central orifice 180 in the incoming direction F180, then by folding the first end portion 62 around the edge attachment 122.

The first end portion 62 comprises a first intermediate portion 620, which extends along the attachment portion 120 of the outer side 104, and a first end portion 622, which extends along the attachment portion 120 on the internal side 102, the first end part being connected to the first intermediate part through the main orifice 180. The first end part 622 ends here with an end 624.

The internal side 102 of the attachment portion 120 is oriented opposite the support 4, so that the end 624 is inserted between the rest of the strip 60 and the support 4.

The strip 60 is installed around the support 4, the second end portion 64 still being free.

Then, the second end portion 64 is hooked onto the locking portion 140. The hooking is done here, first of all, by passing the second end portion 64 through the main orifice 180 in the outgoing direction F181.

The second end portion 64 comprises a second intermediate part 640, which extends along the support 4 on the internal side 102 of the locking portion 140, and a second end part 642, which extends along the locking portion 140 on the outer side 104, the second end portion 642 being connected to the second intermediate portion 640 through the main orifice 180. If necessary, the second end portion 64 is cut to the desired size, for example using shears, not shown. In the example illustrated, the second extreme part 642 ends in a second end 644.

The mounting sub-assembly 6 is positioned at the desired location on the support 4, then the strip 60 is tensioned by hand by an operator. If necessary, the operator can use a tool, such as pliers, to grasp the second end portion 64. Such a tool is not shown. In the context of the present description, the term “tension” designates a mechanical tension. As a result of this manual tensioning, on the one hand, the first end portion 622 of the first end portion 62 is pinched between the attachment portion 120 and the support 4 and, on the other hand, the second end portion 64 is pinched between the locking edge 142 and the support 4.

Next, the second end portion 64 is folded around the end edge 144, the fold being marked by localized plastic deformation of the strip 60. More specifically, the second end portion 642 is folded around the end edge 144.

The fixing assembly 2 is then in the configuration represented on the , the loop 100 still being in the assembly configuration. The folds formed by the strip 60 around the fastening 122, locking 142 and extreme 144 edges immobilize the assembly sub-assembly 6 with respect to the support 4.

On the , the buckle 100 is represented in an intermediate configuration between the mounting configuration and the closing configuration. The locking portion 140 is actuated in pivoting relative to the attachment portion 120, around an axis of rotation parallel to the transverse axis A100, from the deployed orientation to the folded orientation, to pass the buckle 100 from the mounting configuration to the closing configuration.

This pivoting movement taking place by plastic deformation of the blades 162 under the action of an operator, the position of the axis of rotation of the pivoting movement is thus not perfectly controlled, and also depends on the position of the junction 164. It is also possible that the movement of the locking portion 140 relative to the attachment portion 120 is a complex movement, including a translational component.

Schematically, the pivot axis is located between junction 164 and transverse axis A100. In the rest of the description, it is assumed, for simplicity, that the movement is a simple pivoting movement, and that the pivoting axis coincides with the transverse axis A100, the principles set out below being transposable to the case of a complex movement or when the pivot axis is offset from the transverse axis A100.

During the pivoting movement, the extreme edge 144 is moved away from the attachment edge 122. The extreme edge 144 moves along a circular path centered on the transverse axis A100 and represented by an arrow in the arc of a circle F144. Similarly, the locking edge 142 moves along a circular trajectory centered on the transverse axis A100 and represented by an arcuate arrow F142. The two arrows F144 and F122 point in the same direction, which is clockwise on the . As a result, during the pivoting movement, the locking edge 142 approaches the fastening edge 122, and a distance L between the fastening edge 122 and the locking edge 142 decreases. In other words, the distance L is less than the mounting distance L1.

The pivoting movement of the locking portion 140 is produced by the action of an operator, who exerts a force on the locking portion 140. As the locking edge 142 approaches the attachment edge 122, the strip 60 , which surrounds the support 4, stretches elastically and the mechanical tension of the strip 60 increases, opposing the effort of the operator.

This effort is exerted for example by using a tool such as pliers, by pinching the second end portion 64 and the locking portion 140 at the level of the extremal edge 144, so that a lever arm of the effort of the operator is as large as possible in relation to the lever arm of the mechanical tension of the strip 60.

The force exerted by the operator at the end edge 144 is represented by an arrow F1, while the mechanical tension exerted by the strip 60 at the locking edge 142 is represented by an arrow F2. The effort F1 of the operator is thus greater than the sum of the tension force F2 of the strip and the force of plastic deformation of the segment 160.

We call D1 a distance between the extreme edge 144 and the transverse axis A100, and D2 a distance between the locking edge 142 and the transverse axis A100.

The distance D1 is the greatest possible, taking into account the bulk constraints of the loop 100, to increase the lever arm of the force F1. In practice, the distance D1 is between 1 cm and 4 cm, preferably between 2.5 cm and 3.5 cm, for example equal to 3 cm.

Optionally, the operator completes the pivoting movement of the locking portion 140 with respect to the attachment portion 120 by hammering the loop 100 using a tool, such as a hammer or a mallet, to conform the attachment 120 and locking 140 portions on the support 4 and to further mark the folds of the strip 60.

On the , the pivoting movement of the locking portion 140 relative to the attachment portion 120 is complete: the locking portion 140 is in the folded-down position, and the buckle 100 is in the closed configuration. The locking edge 142 and the extremal edge 144 are each closer to the attachment plane P120 than in the mounting configuration, and the distance L has a minimum value, called the attachment distance L2, which is less than the distance from L1 assembly. As a result, the loop 100 exerts a tensile force on the first end portion 62, relative to the second end portion 64, thus tightening the strip 60 around the support 4.

It is understood that the elastic elongation of the strip 60 at the end of the pivoting phase depends, among other things, on the distance D2, the angles of the locking plane P140 with respect to the attachment plane P120 in the deployed position and in the position folded down. In other words, the increase in mechanical tension F2 of the strip 60 depends on the distance D2: the greater the distance D2, the greater the increase in the mechanical tension F2. A person skilled in the art will know how to determine the appropriate distance D2 depending on parameters such as the geometry and the material of the strip, depending on the geometry of the rest of the loop 100, etc., so that at the end of the pivoting phase, the mechanical tension F2 is sufficient to fix the object 8. In practice, the distance D2 is greater than 1 mm, preferably greater than 3 mm. In the example illustrated, the distance D2 is equal to 3 mm, so that the tension F2 of the strip 60 is greater than 50 daN at the end of the pivoting movement.

It is understood that the greater the distance D1 is compared to the distance D2, the more the operator benefits from a favorable lever arm for the effort F1 that the operator must exert is proportionally reduced. In practice, the ratio of distance D1 divided by distance D2 is greater than or equal to 0.5, preferably greater than 1.

A loop 200, in accordance with a second embodiment of the invention, is shown in . In the second embodiment, elements similar to those of the first embodiment bear the same references and operate in the same way. In the following, the differences between the first and second embodiments are mainly described.

Buckle 200 is shown in the mounting configuration, in which the outer side 104 forms a hollow. Thus, the attachment plane P120 and the locking plane P140 intersect along a transverse axis A200 of the buckle 200. The locking portion 140 is oriented in a deployed orientation with respect to the attachment portion 120, around the A200 thru axle.

The attachment portion 120 does not include a notch of the type of the notch 124 of the buckle 100 of the first embodiment, but has a serrated attachment edge 122, in order to reduce the risk of the first portion slipping. terminal 62 during its establishment.

A first hole 126, which here has an oblong shape parallel to the transverse axis A200, is made in the attachment portion 120, to allow the passage of the first end portion of the strip 60, not shown on the . Other ways of fixing the first end portion of the strip to the attachment portion 120 are thus possible, by passing the strip 60 through the main orifice 180 and through the first hole 126.

The locking portion 140 also includes a second hole 148, which here has an oblong shape parallel to the transverse axis A200 and which allows the second end portion 64 to pass from the outer side 104 to the inner side 102. The extreme edge 144 is thus directly accessible so that an operator can exert a force F144 directly on the locking portion 140, without risking damaging the second end portion 64.

The locking portion 140, which was flat in the first embodiment, is curved here, with a convexity oriented towards the external side 104, which makes it possible to stiffen the locking portion 140. On the other hand, a rib 146 of stiffening is provided in the locking portion 140, so as to limit the deformations of the locking edge 142 when the loop 200, attached to a strip, changes from its attachment configuration to its closure configuration. The rib 146 is provided during the manufacture of the loop 100, for example by stamping.

In a variant not shown, other ribs are formed in the loop 100, for example in the junction 164 connected to each of the blades 162, to stiffen the junction 164, while the blades 162, without ribs, are comparatively more flexible. Thus, when the locking portion 140 passes from its deployed position to its folded position, the plastic deformation of the buckle 100 or 200 takes place mainly at the level of the blades 162.

Loops 100 and 200 each have a constant thickness. In a variant not shown, the blades 162 have a thickness less than a thickness of the rest of the loop 100 or 200, in particular less than a thickness of the junctions 164, so as to locate the plastic deformations mainly at the level of the blades 162.

Any feature described for one embodiment or variant in the foregoing may be implemented for the other embodiments and variants described previously, as far as technically feasible.
