Definitions

  • the invention relates to a method of fitting necklaces ear bands particularly suitable for chains mounting products such as hoses especially in the automobile sector ; the invention also relates to tools implementing the method.
  • the invention relates to necklaces which are conventionally made from a strip of strip shaped in a generally circular ring.
  • the ring in question is likely to deform by spacing of its two ends which creates a couple of elastic return used as tightening; among these types of necklaces we will focus more specifically on those whose the two ends of the spring band come overlap; a median cut of the collar band extends a few centimeters at one end to form a passage for the other which is decreased in width to coincide with said passage.
  • Both ends of the band are provided with an ear obtained by simple rectangular folding of its external parts towards the outside of the collar of such so that, thanks to a clamp provided with jaws, one can easily bring the two control ears together, i.e. enlarge the diameter of the collar providing when releases them, the elastic return torque necessary for tightening, for example of a hose on a pipe.
  • the operation of preloading of the collars made inside the dispenser eliminating the danger of ejection nuisance and breakage commonly seen with tools handbags when inserting necklaces between their jaws.
  • a hand tool for extraction and installation particularly suitable for implementing the method described above.
  • such a tool comprises two bit facing, shaped to fit the ears of a elastic collar and arranged at the end of two branches articulated to be able to deploy in V in order to cooperate with the stationary collar distributor equipped with its pre-compression system as we said;
  • the installation tool is provided with a blocking allowing free and automatic operation of the mechanism with a view to reconciling bit to load a necklace and on the contrary, prohibiting reverse movement except when actuating a command provided for this effect to automatically spread the movable jaws.
  • the release device jaws which will be specified later does not know any progressiveness so that the positioning of the collar is extremely brief, which can lead in some situations with a lack of precision in its positioning on the clamping area. This is the reason two other variants of the laying that can implement the process according to the invention which allows a more gradual relaxation of bit when mounting the collar on the hoses.
  • the installation tool now includes two branches, one of their ends, jaws and one joint to the other to open freely under the action of the load of the collar from a close position or the jaws maintain compression of the collar to a position deployed in V allowing the jaws to engage or to be disengage from the ears of the collar when it is respectively waiting on the fixed distributor, or unloaded after its installation on the hose, cooperating with means so that when said branches are mounted by sliding their articulated ends along their longitudinal axis inside and in abutment at bottom of a case, only the jaws emerge from the mouthpiece of said case with which the branches cooperate to be kept in close position and stabilized by braking means and vice versa, when said branches are gradually slid outwards under the commanded action of the load of the collar up to a stopper close to the mouth of the case, they are deploy in V thanks to an elastic member repelling them mutually.
  • the method of fitting elastic collars 1 in accordance with the invention includes a necklace dispenser 2 allowing as illustrated in Figure 1, to stack the necklaces 1 on their edge, along a column vertical 3 having substantially the external dimensions of the closed collar, and having a front opening 4 of dimension strictly greater than the spacing of the members opening elastic collars 1 called later "ears" 5.
  • the vertical column 3 opens in its part lower 6 on a case 7 of slightly height greater than the width of the band of the collars 1; the lateral cutout 4 allows to clear, by guiding them, the control ears 5 of the collars 1 which are distributed by gravity one by one, as will be indicated below, at as and when they are extracted from the housing 7 by means a hand tool 8; the latter is equipped with two jaws 9 mounted at the ends of two branches 10 which will, before extraction by the user, close to each other by two compression shoes 11 arranged on the side and other of the same branches 10 and which are animated with a lateral movement towards each other, as shown in the Figure 2 advantageously by a mechanical device motorized, controlled automatically or step by step by the user.
  • the user can then very precisely position the collar 1 using tool 8, on a hose 12 previously installed on a pipe 13 for example of a motor vehicle.
  • the elastic collar 1 must be released by tool 8 so that it resumes its original diameter and thus counter-tighten the hose 12 on pipe 13.
  • tool 8 is fitted with a release mechanism, several of which variants will be described later.
  • the elastic collars 1 stacked on edge in the column 3 of the distributor 2 constitute a supply automatic collars arriving in the housing 7, by example, placed on a support table near the place of job ; the collar 1 at the bottom of column 3 in the housing 7 is therefore in the waiting position for a extraction by tool 8; naturally the necklace 1 previous will be maintained by a blocking system retractable 16 successively erased to allow the lowering of the collar awaiting extraction.
  • the mechanism first includes two clogs positioning 17 coming to be housed on either side of ears 5 of the collar 1 pending, so as to block the collar 1 in this position (in strong lines on the fig. 6); at this moment, we can introduce the branches 10 of tool 8 (not shown) so as to make coincide the jaws 9 respectively on the ears 5 of the necklace 1 pending.
  • Tool 8 abuts on the shoes 17 which hold the collar 1 in position and is laterally guided on the two shoes 11 which will serve later to move towards each other, the two ears 5 in order to widen the collar 1 (position in dashed in fig. 6).
  • the hooves 11 can be motorized controlled by branch position sensors 10 of tool 8 or by pressure sensors when these same branches are in contact with the faces of compression of the hooves 11.
  • tool 8 is designed to maintain compression ears 5 of the collar 1 thus prestressed, throughout transport from distributor 2 to the installation site of the collar 1.
  • a link 24 is articulated, the length of which again depends on the general geometry of the tool which will be easily determined by a person skilled in the art; the free ends of the two rods are joined and articulated around the same axis 25 secured to a yoke 26 connected in a manner which will be specified below to a rod 27 which can move along the axis XX 'inside of the tool 8, guided by a longitudinal channel 28 provided in the center of the body 21; the rod 27 is also secured to the yoke 26 in an upper cavity 29 of the body 21 leading to a cavity 30 inside the head 20 of sufficient size to allow the lateral extension of the ends of the branches of length b of the branches 10 when these deploy around their articulation 23; the rod 27 extends itself towards the handle 22 to come into elastic abutment 31 on a member, such as a helical spring 32 for example, which tends to push said rod 27 longitudinally towards the head 20 of the tool 8, thus tending to separate the jaws 9
  • the general kinematics of the tool 8 in accordance with this first variant will now be specified: by the external action of the shoes 11 of the distributor 2 according to the arrows F2 of the drawing, the branches 10 articulated at point 23 move simultaneously according to the arrows F3 thereby causing a displacement F4 of their branches of length b , the four elements of the branches then take the configuration in thin dashed lines in the figure and it is clear that the articulation 25 of the two links 24 undergoes in this movement an offset in the axis XX 'of the tool towards its rear part, that is to say towards the handle (arrow F5).
  • the system of blocking of the rod 27 is obtained by giving said rod an adequate axial taper of increasing section from the yoke 26 to the elastic stop 31 coming to collaborate with a conical key 35 of adequate conicity with an axis perpendicular to that of the rod 27 and being able to move axially from top to bottom (FIG. 8) by an action of the control 14 and from bottom to top (by the reaction of an elastic member 36, in principle a helical spring), said key 35 being arranged in a well 37 to come constantly into friction with the conical part of the rod 27 so that its smallest section being at the top (fig.
  • the taper of the rod 27 results from a dish machined along one of its generators, at least over an effective length corresponding to its axial displacement during maximum jaw travel free 9, along a machining slope in the radial direction providing a progressive ramp 40 capable of cooperating with the conical key 35, the slope of the ramp 40 being precisely calculated to obtain a relative slip with the key 35 in one direction and a blocking in the other in depending on the mechanical characteristics of the tool 8 and necklaces 1.
  • the conical key 35 is of the type cylindrical cutaway key known as "bicycle key", the upper end of which is smaller section, opposite the return spring 36 bearing on the internal wall of the body 21 of the tool, opens freely outside the body in order to be accessible by pressing the user down (fig. 8 or fig. 11) when it wishes to release the tool 8 from the collar 1 correctly positioned on the hose, a trigger command 14 advantageously relieving stress necessary to repel said key 35.
  • the head 20 of tool 8 can be fully rotated on itself around the longitudinal axis XX 'thus allowing rotate in all directions of space the plane containing the two branches 10 supporting the jaws 9.
  • This perfecting the tool is particularly advantageous to avoid any contortion of the hand of the user both at the time of extracting the collars that at the time of their positioning.
  • the rotation of the head 20 around itself the axis XX ', around a circular rail 41 at the end of the body 21 of the tool, is made possible by mounting particular of the yoke 26 which is naturally driven by the rotation of the head 20 at the same time as the branches 10, around the head 42 of rod 27 which cannot undergo no rotation on its own due to its ramp 40 which must remain vis-à-vis the ramp of the key 35; such an arrangement is for example obtained by the collaboration of a flared stem head 42 to provide a shoulder coming to cooperate with a housing provided at the base of the yoke 26 just surrounding the head 42 of the rod in such a way that it ensures mutual rotation of two pieces but that it prohibits any translation axial.
  • the branches 10 of the tool 8 supporting the jaws 9 can be inclined at an angle varying from 0 to 90 ° to the plane they determine when they are straight according for example to Figures 9 and 10 drawings.
  • the inclination of the branches 10 can be finalized at construction of tool 8 or, according to a conventional construction that is well known to the skilled person, can be adjusted to will by the user from a vertical position of Figures 9 and 10 to a 90 ° end position allowing lateral gripping of elastic collars.
  • the single or variable inclination of the branches 10 can be associated with the rotary head 20 described in the previous execution to form a particularly universal tooling.
  • the autonomous installation tool 50 which will now be described in reference to FIGS. 12 to 20 implements all of the steps in the assisted fitting process for elastic collars described above.
  • the autonomous installation tool 50 which will now be described in reference to FIGS. 12 to 20 implements all of the steps in the assisted fitting process for elastic collars described above.
  • the tool 50 cooperates with a distributor 2 of collars 1, arranged at a fixed station to preload them, i.e. open them, bringing their controls together, ears 5, at by means of two compression shoes 11 animated by a lateral movement towards each other by a device mechanical advantageously, but not necessarily, motorized can be controlled automatically or suddenly by kick by the user himself.
  • FIG. 17 and 18 An example of a distributor 2 fitted with clogs motorized and automatically controlled compression cooperation with hand tool 50 is shown in Figures 17 and 18 attached; its operation will be detailed later.
  • the installation tool 50 comprises two normally identical branches 51 provided with one of their jaw ends 52 mounted facing each other to be able to fit on the ears 5 of an elastic collar classic; by their other end the branches 51 are articulated with each other in the plane it forms along an axis 53 which is perpendicular to it to open freely between a close position putting the jaws 52 in the open position of the collar 1, up to a deployed position in V, positioning the same jaws for engage or disengage from the ears 5 of the collar 1 respectively waiting on dispenser 2 or unloaded after installation; as shown in figure 13, the axis of articulation 53 of the two branches 51 is mounted at sliding along the longitudinal axis of symmetry of branches 51 inside a case 54, shaped externally to serve as a grip the tool 50 and internally, so that when the branches 51 are inside said case 54 and in stop at the bottom of the same case, only the jaws 52 emerge from the mouth 55 of the case 54 over a distance shown in Figures 15 and 16, sufficient to maintain the ears of
  • the articulated branches 51 each have along their outer edge 59 at least a succession of three facets 60,61,62 plane and perpendicular to the plane of the branches 51 when they are deployed, connecting along a convex profile as shown on the left branch of Figures 12 and 13 in particular; a first facet 60 extends from the jaw 52 inside the branch 51 to flare outwards over a distance corresponding to the part remaining external when the branches 51 are in abutment inside the case 54 as shown in Figures 15 and 16; a second facet 61 is connected to the first at an angle bringing it into a parallel or slightly reentrant position relative to the vertical plane of symmetry of the V of the branches 51 over a distance a which will be specified below; finally the third facet 62 is connected to the second at an inclination inwardly sloping in the direction of the hinge axis 53.
  • Skids 63 of maximum width a are mounted on pivots 64 perpendicular to the plane of the branches of on either side of the internal side walls of the enlarged part 58 of the mouth 55 of the case 54 to come collaborate with the second and third facets 61 and 62 of the branches, respectively to first create sufficient braking of the branches 51 when these are in abutment inside the case 54 and therefore stressed to the maximum by the elastic load of the open collar which therefore tends to push them out of the case, and a on the other hand, to facilitate the extraction of the branches 51 from the case 54 at the time of the removal of the collar 1 on the hose 12 by balancing and making progressive the deployment of said branches 51.
  • the two arms 51 machined from special steel for shape the jaws 52 and the different facets 60,61,62 as well as the notch 65 according to the characteristics detailed above, are hinged together to deploy in V thanks to a pivot 53 perpendicular to the plane branches and protruding on either side of this plane to serve as sliding lugs between two lights 66 superimposed extending in the axis of symmetry of the tool over a distance between a lower stop 67 corresponding to the position of the tool when its branches 51 are brought together inside the case 54 and an upper stop 56 corresponding to the position of the branches fully deployed in V as it was said upper ; naturally the axis 53 of articulation of branches slides without play between these two stops 56.67.
  • the two lights 66 are made on two pieces metal 68 advantageously identical and shaped general of T, cut from sheet metal to form the framework of the internal mechanism of the tool 50. Between the transverse parts of the T of parts 68, are mounted on pivots 64, two pads 63 so that the latter can oscillate freely on either side of facets 62 of the external edge 59 of each branch 51 which are constantly held in position against said pads 63 thanks to a pair of spiral springs 57 mounted in suitable accommodation just above the hinge pin 53.
  • the two parts 68 are held one above the other by the two axes of articulation 64 of the skids 63, serving as a spacer in the part upper of the T and by a spacer of the same type 69 provided at the lower end of parts 68.
  • the branches 51 of the tool 50 are in the deployed position, that is to say in the position of extraction of the collars on the platform 80 from distributor 2.
  • Tool 50 comes into distributor by a transverse movement P (fig. 18) around the ears 5 of the collar 1 pending in the internal case, in such a way that the jaws 52 of the tool come to the contact of the two compression shoes 11 automatically actuated by two cylinders 81 arranged opposite and preferably activated as soon as the tool 50 is in good place ;
  • the distributor 2 could be constituted by different means than those presented Figures 17 and 18; in particular, the cylinders 81 actuating the shoes 11, could be replaced by a manual mechanism to multiply an action of the foot or of the user's hand in an environment where it would be difficult to bring a source of compressed air through example;

  • the thumb wheel 116 can then rotate freely in both directions of the arrow B (fig. 26) by floating around the fixed shaft 119 in a substantially centered position and the notched branch 101 can then move freely in translation in the direction of arrow A (fig. 6).
  • the ring gear 117 of the dial 116 is associated with two side cheeks 122 bored, forming together a housing suitable for receiving, by the bore, the elastic ring 121 mounted on the support shaft 119 fixed to the case 104, the diameter of the cheek bore 122 being calculated, at a minimum, to obtain sufficient displacement to create the blocking effect and, at most, to limit the crushing of the ring 121 and thus avoid its deterioration, during heavy load resulting from the use of large necklaces 1.
  • the roller 125 only comes to rest on the notched area 109 of the corresponding branch 101; thus, as long as the trigger 123 is not actuated by pressing on the handle 123 a , the roller 125 has no effect on the branch 101 which remains braked on the transverse stops 113,116 due to the force F resulting from charging the collar 1 pre-compressed.
  • the external edge 109 of the notched branch 101 comprises over its entire useful sliding length, that is to say the length of the edge capable of entering contact with the transverse stop 113 or 116, a notched area 109 a and at least one smooth co-lateral area, preferably two 109 b , 109 c , coming from either side of the notched area on which, or on which comes to bear at least part of the smooth tread 127 (fig. 31) of the control roller 125 which can thus roll freely on the said smooth area (s) 109 b , 109 c while exerting a force R (fig. 30 ) tending to push the branch 101 towards the branch 102, thereby releasing the deployment of the same branches.
  • the roller 125 is provided on a part of its peripheral strip, with a ring 128 made of flexible and elastic material, for example made of elastomer, with an external diameter larger than that of the tread 127 of the roller thus providing a damping effect in the first control phase, when the trigger 123 is actuated, by creating an elastic support of said ring 128 on the notched area 109 a of the corresponding branch 101, making its sound more progressive and more flexible passage from the braked position (fig. 29) to a free deployment position (fig. 30).
  • a ring 128 made of flexible and elastic material, for example made of elastomer
  • the roller 125 consists of two metal cheeks 129 joined on either side of an elastomer ring 128 mounted on the same shaft 126, of larger diameter and thickness identical to the width of the notched area 109 a extending over the central area of the outer edge 109 of the notched branch 101, framed on the left and on the right by two smooth treads 109 b and 109 c which come to the right of the smooth tread 127 of each cheek 129 of the roller 125, to transmit the force R (fig. 30) to the branch 101.
  • the height of the teeth 101 a of the notched area 109 a on the outer edge 109 of the corresponding branch 101 increases regularly from the head of this branch 101 to its end close to the joint 53 without changing the general shape of the toothing so as not to modify its relationship with the toothing 117 of the dial 116 in particular; it has therefore been imagined to machine the smooth areas 109 b and 109 c of the external edge 109 of the notched branch 101 so as to give them a progressive inflection from the head to the other end close to the joint.
  • the trigger 123 carrying the shaft 126 and the roller 125 is mounted on its axis 124 by means of two nozzles 134 open upwards which are fitted by the underside around said axis 124 so that the trigger 123 is held at its end by the two hooks 134 and supported by the roller 125 on the edge 109 of the notched branch 101 by the embedding of the adjustment member 132 of the eccentric shaft 126 in the housing 133 of the case 104.
  • each head of the branches 101 and 102 comprises a rotary jaw 103 which can be oriented in a plane perpendicular to the plane of branches along an axis zz 'passing through the two heads in the median plane of the branches, which allows the installation of necklaces 1 in almost any position the tool 100 depending, as we said, on the size of the mounting area. Indeed, by combining the possibility of rotation of the tool, around the collar, with the possible inclination provided by the rotation of the jaws 103 as just said, tool 100 can be steered in all directions of space for the same position final of a necklace 1.
  • the bit 103 of one of the branches 101 has a lug 137 which appears in the figures of the sectional tool and in particular in FIGS. 27 and 28, extending perpendicularly towards the jaw of the other branch 102 which is provided with a corresponding housing 138, in such a way that lug 137 exactly matches housing 138 when the two jaws 103 are brought together, as shown for example in Figures 22 and 23.
  • branches 101 and 102 are close together and it is possible to give the necklace 1 an inclination which can vary appreciably more or minus 90 ° on either side of the median plane of the tool for find the most suitable installation position.
  • jaws 103 are equipped with a automatic recall mechanism, shown in Figures 34 and 35, towards a rest position corresponding to a aligned grip of the necklaces, as soon as the branches are discharged.
  • This jaw recall mechanism 103 from a angular position of their median axis xx 'to the left or to right of the median longitudinal axis of the heads yy ', from plus 90 ° to the rest position where the axis xx 'coincides with the axis yy ', consists of an elastomer rod 140 advantageously cylindrical and maintained when it is at rest, in the axis yy 'of the heads, fixed on one side and sliding on the other, inside a clevis 141 integral with the head and passing through the rotation shaft 142 the jaw when in the rest position, i.e.
  • this mounting of the rod 140 across the shaft 142 of the jaw advantageously provides not only the maintenance of said bit on the head of the branches as shown in section on Figure 36, but also the elastic return effect angular resulting from the transverse twist to the left or to the right of the elastomer rod 140 deformed by the shaft of rotation 142, as shown in FIG. 35; a recess 143 in the yoke 141 of the head and surrounding the rotation shaft 142 is provided to absorb the deformations of the elastomeric rod 140 when it is twisted.
  • the assembly of the jaws 103 with reminder automatic on branch heads is extremely simple: the rotation shaft 142 of the jaw is centered in the clevis 141 of the head and aligned with it so that the elastomeric rod 140 can be introduced through a hole extending axially from the distal end of the head towards the branch and in such a way that the rod 140 comes go through a radial tunnel through the shaft 142 to to be finally counter-blocked by a simple ball 144 arranged before mounting in the yoke141; a 145 plate is provided to lock the rod 140 on the ball 144 as well as the entire head by the sole means of a screw 146 (fig. 36).
  • the case 104 is constituted by two shells 104 advantageously identical, in plastic material shaped externally to serve as a gripping member to the tool 100 ; the two shells 104 a are fixed opposite one another by screws 147, 148 and 149 as well as by the axis 124 advantageously used for the rotation of the trigger 123, so as to be able to grip on the one hand the two branches 101 and 102, being arranged on either side of the plane formed by said branches, a longitudinal groove 107 being formed on the internal face of each shell to accommodate the ends of the joint 53 of the branches advantageously equipped with ball bearings 108 in order to ensure their sliding between the front 106 and rear 105 ends of said grooves 107 serving as stops, and to grip on the other hand a metal cage 150 comprising two flanges 150 a and 150 b advantageously identical and mounted opposite , at equal distance thanks to intermediate spacers 151 taken between the screws 147, 148 and 149; this cage 150
  • L 'guide member may be a plate 152 taken from a low friction material, for example silicone, embedded in the two side flanges 150 a of the cage 150, slightly projecting in direction lateral faces of branches 101 and 102.
  • the guide member can be made up of one or more rollers with a parallel axis (not shown in the figures), fixed in the thickness lateral flanges of the metal cage 150 to come resting on the lateral faces of the branches in a generator perpendicular to the direction of their sliding.
  • Tool 100 as just described in its different configurations, can be used according to Figures 17 to 20 which detail the operation general of the installation tool 50 corresponding to the variant previous in cooperation with distributor 2 for tighten a hose 12 on a line 13 by means of a band collar 1.
  • the improved tool 100 makes it possible to in addition a total control of the discharge of the collar 1, and even in a very crowded environment.
