Definitions
- the invention relates to a method of fitting elastic ear collars particularly suitable for assembly lines for products such as hoses, particularly in the automotive sector; the invention also relates to tools implementing the method.
- the invention relates to necklaces which are conventionally manufactured from a strip of strip shaped in a generally circular ring.
- the ring in question is capable of being deformed by spacing its two ends which creates an elastic return torque used as a tightening; among these types of necklaces we will focus more particularly on those whose two ends of the spring band overlap; a median cut of the band of the collar extends over a few centimeters at one of its ends to form a passage for one other which is reduced in width to coincide with said passage.
- the two ends of the strip are provided with a drive lug obtained by simple rectangular folding of its external parts towards the outside of the collar so that, thanks to a clamp provided with jaws, it is easy to bring the two lugs together. control that is to say, enlarge the diameter of the collar providing when released, the elastic return torque necessary for tightening, for example of a hose on a pipe.
- a hand tool for extraction and installation particularly suited to the implementation of the method described above.
- such a tool comprises two jaws facing each other, shaped to adapt to the ears of an elastic collar and arranged at the end of two articulated branches so as to be able to deploy in a V shape in order to cooperate with the distributor of post collars. fixed with its pre-compression system as we said;
- the fitting tool is provided with a blocking system allowing the mechanism to operate freely and automatically with a view to bringing the jaws closer together to load a collar and, on the contrary, prohibiting reverse movement unless actuating a command provided for this purpose to automatically spread the movable jaws.
- the device for loosening the jaws which will be specified below knows no progressiveness so that the positioning of the collar is extremely brief, which can lead in certain situations to a lack of precision in its positioning on the area of Tightening. This is the reason why two other variants of the setting tool are also proposed which can implement the method according to the invention which allows a more progressive loosening of the jaws at the time of mounting of the collar on the hoses.
- the installation tool now comprises two branches provided, one of their ends, jaws and a joint to each other to open freely under the action of the load of the collar from a close position or the jaws maintain the compression of the collar to a deployed position in V allowing the jaws to engage or disengage from the ears of the collar when the latter is respectively waiting on the fixed distributor, or discharged after its installation on the hose, cooperating with means so that, when said branches are mounted by sliding from their ends articulated along their longitudinal axis inside and in abutment at the bottom of a case, only the jaws emerge from the mouth of said case with which the branches cooperate to be kept in the close position and stabilized by braking means and conversely, when said branches are progressively sliding outward under the controlled action of the load of the collar up to a stop e stop close to the mouth of the case, they deploy in a V thanks to an elastic member repelling them mutually.

- FIG. 36 is a representation in elevation and in median section of the jaw equipping the head of the notched branch of the tool in its third variant,
- the method for installing elastic collars 1 in accordance with the invention comprises a distributor of collars 2 making it possible, as illustrated in FIG. 1, to stack the collars 1 on their edges, along 'a vertical column 3 having substantially the external dimensions of the closed collar, and having a front opening 4 of dimension strictly greater than 1 spacing of the opening members of the elastic collars 1 hereinafter called "ears" 5.
- the vertical column 3 opens in its lower part 6 onto a housing 7 of height slightly greater than the width of the band of the collars 1; the lateral cutout 4 makes it possible to release, by guiding them, the control ears 5 from the collars 1 which are distributed by gravity one by one, as will be indicated below, as they are extracted from the housing 7 by means of '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, be brought towards each other by two compression shoes 11 arranged on the side and other of the same branches 10 and which are driven in a lateral movement towards each other, as shown in Figure 2 by a mechanical device advantageously motorized, controlled automatically or piecemeal by the user.
- the user can then very precisely go and position the collar 1 by means of the tool 8, on a hose 12 previously placed on a pipe 13 for example of a motor vehicle.
- the elastic collar 1 must be released by the tool 8 so that it returns to its original diameter and thus counter-tightens the hose 12 on the pipe 13.
- the tool 8 is fitted with a release mechanism, several variants of which will be described below.
- the elastic collars 1 stacked on edge in the column 3 of the distributor 2 constitute an automatic supply of collars arriving in the housing 7, for example, placed on a support table near the workplace; the collar 1 at the bottom of the column 3 in the housing 7 is therefore in the standby position for extraction by the tool 8; naturally, the preceding collar 1 will be maintained by a retractable blocking system 16 which is successively erased to allow the collar to descend while awaiting extraction.
- the dispensing mechanism first comprises two positioning shoes 17 which are housed on either side of the ears 5 of the standby collar 1, so as to block the collar 1 in this position (in strong lines in fig. 6); at this instant, the branches 10 of the tool 8 (not shown) can be introduced so as to make the jaws 9 coincide respectively on the ears 5 of the standby collar 1.
- the tool 8 abuts on the shoes 17 which hold the collar 1 in position and is guided laterally on the two shoes 11 which will later serve to bring the two ears 5 towards each other in order to widen the collar 1 (dotted position in fig. 6).
- the shoes 11 are automatically or by manual control, brought closer to each other, according to the arrows F2 of FIG. 6; in the case of an automatic triggering, the motorization of the shoes 11 can be controlled by position sensors of the branches 10 of the tool 8 or also by pressure sensors when these same branches are in contact with the compression faces of the shoes 11.
- the collar 1 is then in the open position and removal is made not only of the shoes 11 but also of the shoes 17 in order to release (inversion of the movements FI and F2) the opening of the housing 7 and thus easily extract the preloaded collar 1.
- the tool 8 is designed to maintain the compression of the ears 5 of the collar 1 thus prestressed, during the entire transport from the distributor 2 to the place of installation of the collar 1. It will it goes without saying that other provisions could be adopted in particular for the configuration of the dispenser 2 in accordance with the invention; we can in fact separate the function of distributing necklaces from the function pre-tightening obtained by bringing the shoes 11 closer together by mechanical means, for example motorized.
- 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 following 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 of the figure and it is clear that the articulation 25 of the two links 24 undergoes in this movement a shift in the axis XX 1 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 flat machined along one of its generatrices, at least over an effective length corresponding to its axial displacement during the movement maximum of the free jaws 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 sliding with the key 35 in a direction and blocking in the other depending on the mechanical characteristics of the tool 8 and the collars 1.
- the conical key 35 is of the cylindrical key cutaway type known as the designation "bicycle key", the upper end, of smaller section, opposite the return spring 36 bearing on the internal wall of the body 21 of the tool, uche freely outside the body in order to be accessible by a downward pressure from the user (fig. 8 or fig. 11) when it wishes to release the tool 8 from the collar 1 correctly positioned on the hose, a control trigger 14 advantageously relieving the effort necessary to push said key 35 back.
- the head 20 of the tool 8 can be pivoted totally on itself around the longitudinal axis XX ′ thus making it possible to pivot in all directions of space the plane containing the two branches 10 supporting the jaw 9.
- This improvement of the tool is particularly advantageous to avoid any contortion of the hand of the user both at the time of extraction of the collars and at the time of their positioning.
- the branches 10 of the tool 8 supporting the jaws 9 can be inclined at an angle varying from 0 to 90 ° relative to the plane which they determine when they are straight in accordance with example in Figures 9 and 10 of the drawings.
- the inclination of the branches 10 can be carried out definitively when the tool 8 is constructed, or else, according to a conventional construction which is well known to those skilled in the art, can be adjusted at will by the user. from a vertical position in Figures 9 and 10 to a final position at 90 ° allowing lateral gripping of the elastic collars.
- the single or variable inclination of the branches 10 can be associated with the rotary head 20 described in the previous embodiment to form a particularly universal tool.
- the autonomous installation tool 50 which will now be described with reference to FIGS. 12 to 20 implements all of the steps of the assisted installation process of elastic collars described above.
- the parts and parts of parts mentioned in the description which follow and which are already used in the first variant will be referenced in the same way.
- the tool 50 cooperates with a distributor 2 of collars 1, arranged at a fixed station to preload them, that is to say open them, by bringing their control members, the ears 5, by means of two compression shoes 11 driven in a lateral movement towards each other by a mechanical device advantageously, but not necessarily, motorized which can be controlled automatically or piecemeal by the user himself.
- FIGS. 12 to 16 An example of a distributor 2 equipped with motorized compression shoes and automatically controlled in cooperation with the manual tool 50 is shown in Figures 17 and 18 attached; its operation will be detailed later.
- the fitting tool 50 will now be described: it comprises two normally identical branches 51 provided at one of their jaw ends 52 mounted facing each other so as to be able to adapt to the ears 5 a classic elastic necklace; by their other end the branches 51 are articulated with each other in the plane which 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 situation of the collar 1, to a deployed position in V, positioning the same jaws to engage or disengage from the ears 5 of the collar 1 respectively waiting on the distributor 2 or unloaded after installation; as shown in FIG.
- the articulation axis 53 of the two branches 51 is mounted to slide along the longitudinal axis of symmetry of the branches 51 inside a case 54, shaped externally to serve as a member for gripping the tool 50 and internally, so that when the branches 51 are inside said case 54 and in abutment at the bottom of the same case, only the jaws 52 emerge from the mouth 55 of the case 54 on a distance shown in Figures 15 and 16, sufficient to keep the ears of a collar 1 in good position; at this moment the branches 51 are in a close position against the internal side walls of the case 54; the tool 50 is in the autonomous working position consisting, as will be said later, in extracting a collar 1 from the distributor 2 bringing it to a hose in its open position in order to position it on a pipe before releasing the necklace; in this regard, and conversely when the branches 51 of the tool 50 are slid towards the outside of the case 54 up to a stop stop 56 near the mouth 55 of the case, they are then found in the deployed position in V as shown in section in
- 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 and collaborate with the second and third facets 61 and 62 of the branches, respectively to first create sufficient braking of the branches 51 when they 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 on the other hand, to facilitate the extraction of the branches 51 from the case 54 when removing the collar 1 on the hose 12 by balancing and making progressive the deployment of said branches 51.
- a notch 65 on the lower part of the third facet 62 of each branch 51 allowing each shoe 63 to come to be embedded in the branch 51 corresponding to the moment when the axis hinge 53 of the deployed branches come into abutment 56 on the side of the mouth 55, creating a sudden increase in opening of the same branches 51; at this time, the jaws 52 are completely disengaged from the ears 5 of the collar 1 fully discharged on the hose 12 which authorizes the resumption of the tool 50 for a new operation towards the distributor 2.
- the embedding of the pads 63 in the notches 65 constitute a fleeting position for waiting for the branches 51 which benefit in this way from opening stability with regard to external stresses on the tool for example, when it is placed in the distributor 2 as it will be said later.
- the two branches 51 machined in special steel to shape the jaws 52 and the different facets 60,61,62 as well as 1 '' notch 65 according to the characteristics detailed above, are hinged together to deploy in V through a pivot 53 perpendicular to the plane of the branches and protruding on either side of this plane to serve as sliding lugs between two superimposed lights 66 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 has been said above; naturally the axis 53 of articulation of the branches slides without play between these two stops 56.67.
- the two openings 66 are formed on two metal parts 68 which are advantageously identical and in the general shape of a 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 the parts 68, are mounted on pivots 64, two pads 63 so that the latter can oscillate freely on either side of the facets 62 of the outer edge 59 of each branch 51 which are constantly held in position against said pads 63 by means of a pair of springs spirals 57 mounted in housings provided for this purpose just above the articulation axis 53.
- the two parts 68 are held one above the other by the two articulation axes 64 of the pads 63 , serving as a spacer in the upper part of the T and by a spacer of the same type 69 provided at the lower end of the parts 68.
- two shells 70 are provided to adjust around the two T-pieces 68 and to be fixed by means of screws 71 in threaded bores 72 advantageously provided on said pieces 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 of the distributor 2.
- the tool 50 comes into the distributor by a transverse movement P (fig. 18) around the ears 5 of the collar 1 pending in the internal housing, so that the jaws 52 of the tool come into contact with the two compression shoes 11 automatically actuated by two jacks 81 arranged opposite and preferably actuated as soon as the tool 50 is in good position; it goes without saying that the distributor 2 could be constituted by different means than those presented in FIGS.
- the jacks 81 actuating the shoes 11, could be replaced by a manual mechanism which increases the action of the foot or the hand of the user in an environment where it would be difficult to bring a source of compressed air for example ; similarly, provision is made here for a supply of collars which are stacked on the column 3 of the distributor 2 but this device could be transformed for simpler equipment in which the collars 1 would be arranged one by one, directly on the internal housing of the distributor 2 in good place to be taken between the jaws 52 of the tool 50, as already said.
- the tool-collar assembly which can then be transported from the distributor 2 to the place of installation since this assembly is completely autonomous.
- the tool-collar assembly is arranged around the hose 12 pre-fitted onto the pipe 13, and it is clear that it is easy to position the collar 1 at the location provided by the manufacturer. given the small size of the tool 50.
- the handle 54 of the tool 50 When the collar 1 is in the right place, it then suffices to remove, according to arrow R in FIG. 20, the handle 54 of the tool 50, while resting on the collar 1 which is necessarily against the hose 12 and which therefore can no longer move laterally during the unloading operation which constitutes an improvement over the previous tool.
- the recoil of the handle 54 is also carried out very gradually thanks to the situation of the pads 63 which slide along the branches 51 from the braking facet 61 in the clamped position to the end of the inclined facet 62 ensuring the progressiveness of the recoil; here again, when the pads describing the inclined facet 62 arrive at the indentation 65, an abrupt opening of the branches 51 is then created, definitively releasing the ears 5 from the collar 1 which has remained in good place on the pipe.
- branches 51 which are in principle straight, can take in special cases, curvatures to facilitate the installation of the collars 1; there is nothing to prevent the end part of the arms 51 from being able to be tilted or tilted between 0 and 90 ° relative to the plane defined by them when they are straight, without the operation of the tool 50 n 'be affected.
- the tool 100 cooperates with a distributor 2 of elastic collars 1 arranged at a fixed station to pre-compress the collars 1, that is to say open them by bringing their control members called ears 5 together by means of two pressers or compression shoes 11 driven in a lateral movement towards each other by a mechanical device, advantageously but not necessarily, motorized, which can be controlled automatically or piecemeal by the user.
- a distributor 2 of elastic collars 1 arranged at a fixed station to pre-compress the collars 1, that is to say open them by bringing their control members called ears 5 together by means of two pressers or compression shoes 11 driven in a lateral movement towards each other by a mechanical device, advantageously but not necessarily, motorized, which can be controlled automatically or piecemeal by the user.
- the tool 100 also comprises two branches 101 and 102 provided at one of their ends, called branch heads, with jaws 103 comprising means which will be detailed below to adapt to the ears 5 an elastic collar 1; by their other end, the branches 101 and 102 are articulated with each other in the plane they form, by virtue of an axis 53 which is perpendicular to it to open freely under the action of the load of the collar 1, from a close position where the jaws 103 maintain the compression of the collar, to a deployed position in V allowing said jaws either to engage or to disengage from the ears 5 of the collar 1, depending on whether the latter is respectively waiting on the fixed distributor 2 or unloaded after its installation on a hose 12; various means which will be detailed below, are provided so that, when the arms 101 and 102 are mounted by sliding their ends articulated along their longitudinal axis 1 inside and in abutment 105 at the bottom of a case 104, only the jaws 103 emerge from the mouth of said case with which the branches cooperate to be maintained as shown in FIGS.
- branches 22 and 23 in the close position and stabilized by braking means which will be described later and vice versa, when said branches are progressively slid outwardly under the commanded and controlled action of the load of the collar up to a stop stop 106 close to the mouth of the case 104, they deploy in a V thanks to an elastic member 57 repelling them mutually .
- the means for longitudinal sliding of the two branches 101 and 102 inside the case 104 are provided on one side by the sliding of the hinge pin 53 between two opposite grooves 107, for example hollowed out in the internal wall of the case 104 and it is advantageous to have ball bearings 108 at the ends of the hinge pin 53 ensuring a better cooperation with the guide grooves 107; on the other side, the branches 101 and 102 are guided in their sliding by two stops which are positioned transversely to the mouth of the case 104 on either side of the branches 101, 102 whose outer edges respectively 109 and 110 are machined to constitute for one 102, a smooth track and for the other 101, an at least partially notched track, providing under the load of a compressed collar, a free and sliding guide on the branch 102 and a guide free or braking on the branch 101 by means of a controlled regulation mechanism (a preferred variant of which will be detailed below with reference to FIGS.
- the branches 101 and 102 equipping the tool 100 are machined from a steel plate according to the general shape shown in the figures; it goes without saying that the dimensions, length, width and thickness will be easily calculated by those skilled in the art to ensure the mechanical strength of the installation tool, taking into account the ranges of collars that will be installed using the tool; thus, the external edges 109 and 110 of the branches coincide in principle with the thickness of each branch.
- the transverse stops cooperating with said external edges are formed, for the branch 102 whose outer edge 110 is machined smooth, by a smooth roller 111 freely rotating about a perpendicular axis 112 in terms of branches and secured to the body of the tool, thus providing the branch 102 with free guidance during its sliding.
- the transverse stop cooperating with the external edge 109 at least partially notched is constituted by a fixed pad 113, integral of the body of the tool substantially at the same level as the smooth roller 111 forming the other transverse stop and coming into contact with the notched track 109 to constitute a brake on the natural tendency that the branches have to deploy outwards when they are subjected to the load of a pre-compressed collar as shown for example in the intermediate position in FIG. 27.
- the shoe 113 is made of an elastic material, for example an elastomer mounted according to a slight rear bias on a pin 114 perpendicular to the plane of the branches to come into resilient abutment on the notched part of the branch 101 by virtue of an adjustment shim 115.
- the transverse stop cooperating with the notched edge 109 of the corresponding branch 101 is, with reference to FIGS. 23 to 31, constituted by a wheel, or toothed wheel 116, situated above the notched branch 101 and coplanar with it, of axis O perpendicular to the direction of movement A (fig. 26) of said branch.
- the dial 116 has a toothed ring 117 having at its periphery, a regular alternation of teeth 117a separated by recesses 117b.
- the pitch of the teeth 117a of the toothed crown 117 is equal to the pitch of the teeth 101b of the notched branch 101 and the teeth 117a of the toothed crown 117 are engaged, in the lower part of said crown 117 with the teeth 101a of the branch notched 1 as it appears in FIGS. 25 and 26.
- the toothed ring 117 has a coaxial bore 118 which is crossed by a fixed support shaft 119 of axis Oi parallel to the axis O.
- the support shaft 119 has a fixed diameter lower than that of bore 118 of the thumbwheel 116 so that there is a radial clearance between the internal surface of the bore 118 and the external surface of the shaft 119, this clearance, which could be left free in theory, being, in the present embodiment, filled by an element made of elastic material advantageously an elastomer, as will be said later. Therefore, the ring gear 117 can move transversely, relative to the fixed central support shaft 119, over a short distance (0, O ⁇ ).
- the device is in the blocking position in which the crown toothed 117 is eccentric with respect to the fixed support shaft 119.
- the notched branch 101 is subjected to a force F directed upwards, that is to say towards the axis Oi of the support shaft 119 resulting from the loading of the precompressed collar 1, so that this notched branch 101 has been moved to the high position and that it exerts pressure on the toothed crown 117.
- the toothed crown 117 is pushed back towards the top and the internal surface of its bore 118 is applied against the lower generatrix of the fixed support shaft 119 to which it is tangent.
- the axis O of the thumb wheel 116 is at a certain distance above the axis Oi of the shaft 119 due to the displacement of the notched branch 101 and of the toothed crown 117 upwards, until this crown 117 is in abutment on the shaft 119; the top of the tooth 101a of the notched branch 101 which is engaged in the lower recess 117b of the toothed crown 117, is then located inside the pitch circle P of the teeth 117a, shown in phantom in Figures 25 and 26, so that the two teeth 117a of the ring gear 117 which happen to be the lowest are blocked in the two corresponding neighboring hollows 101b of the notched branch 101. This results in mutual blocking of the branch notched 101 and the wheel 2 with the consequence of immobilization of the notched branch 101.
- the branch 101 when the force F ceases to be exerted on the notched branch 101, that is to say when the rocking mechanism is actuated which will be explained below and which is shown diagrammatically in Figures 29 and 30, the branch 101 then returns to a low arrow H position (FIG. 26) in which the tops of its teeth 101a are located outside the pitch circle P so that the teeth 117a of the ring gear 117 do not are no longer locked in the notches 101b of the notched branch 101.
- the thumb wheel 116 can then rotate freely in the two directions of the arrow B (fig. 26) by floating around the fixed shaft 119 in a substantially centered position and the branch notched 101 can then move freely in translation in the direction of arrow A (fig. 6).
- the radial clearance between the bore 118 of the ring gear 117 and the shaft 119 is advantageously filled by an elastic ring 121 (FIG. 31), for example made of elastomer, which is sufficiently compressible to allow the necessary transverse offset of the wheel 116 relative to the shaft 119.
- an elastic ring 121 (FIG. 31)
- F force
- the dial 116 self-centers immediately, which makes it possible to avoid the "dragging" effects of a idler gear, (the toothed crown 117).
- the ring gear 117 of the wheel 116 is associated with two side cheeks 122 bored, together forming a housing adapted to receive, 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 a displacement sufficient to create the blocking effect and, at most, to limit the crushing of the ring 121 and thus prevent its deterioration , during heavy load resulting from the use of large collars 1.
- a trigger 123 articulated directly or indirectly to the case 104 along a pin 124 of axis parallel to the axis of the transverse stops 113,116, that is to say perpendicular to the plane of the branches 101,102 as shown in the Figure 29, drives a roller 125 mounted on a shaft 126 with an axis parallel to the axis of the pin 124 and positioned between the latter and the control handle 123a of the trigger 123.
- 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 123a, 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 the loading of 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 109a and at least one smooth co-lateral area, preferably two 109b, 109ç, coming from either side of the notched area on which, or 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 zone (s) 109b, 109c_ while exerting a force R (fig. 30) tending to repel the branch 101 to 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 109a of the corresponding branch 101, making its passage more progressive and more flexible 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 of thickness identical to the width of the notched area 109a 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 109b and 109ç 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 101a of the notched area 109a on the external 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 however, change the general shape of the teeth so as not to modify its relationship with the teeth 117 of the thumb wheel 116 in particular; it has therefore been imagined to machine the smooth areas 109b and 109c of the outer 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 the branches along an axis zz 'passing through the two heads in the median plane of the branches, which allows the installation of collars 1 in almost any position of 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 has just been said, the tool 100 can be directed in all directions of the space for the same final position of a collar 1.
- the jaw 103 of one of the arms 101 has a lug 137 which appears in the figures of the tool in section and in particular on the Figures 27 and 28, extending perpendicularly towards the jaw of one other branch 102 which is provided with a corresponding housing 138, so that the lug 137 exactly matches the housing 138 when the two jaws 103 are brought together, as shown for example in Figures 22 and 23.
- the branches 101 and 102 are brought together and it is possible to give the collar 1 an inclination which can vary substantially plus or minus 90 ° on either side of the median plane of the tool to find the most suitable installation position.
- This jaw return mechanism 103 from an angular position of their median axis xx 'to the left or to the right of the median longitudinal axis of the heads yy', at most 90 ° to the rest position where the axis x 'coincides with the yy axis', consists of an elastomeric rod 140 which is advantageously cylindrical and maintained when it is at rest, in the yy axis of the heads, fixed on one side and sliding on the other, inside a yoke 141 integral with the head and passing through the rotation shaft 142 of the jaw when it is in the rest position, that is to say when the axis xx 'and aligned with the yy 'axis of the head; this mounting of the rod 140 across the shaft 142 of the jaw advantageously provides not only the maintenance of said jaw on the head of the branches as shown in section in FIG.
- the assembly of the jaws 103 with automatic return to the heads of branches is extremely simple: the rotation shaft 142 of the jaw is centered in the yoke 141 of the head and aligned with the latter so that the elastomeric rod 140 can be introduced by a hole extending axially from the distal end of the head towards the branch and in such a way that the rod 140 comes to pass in a radial tunnel passing through the shaft 142 to be finally locked by a simple ball 144 disposed before mounting in clevis 141; a plate 145 is provided for locking 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 consists of two shells 104a which are advantageously identical, made of an externally shaped plastic material, to serve as a gripping member for the tool 100; the two shells 104a 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 bearings ball 108 to ensure their sliding between the front ends 106 and rear 105 of said grooves 107 serving as stops, and to grip on the other hand a metal cage 150 comprising two flanges 150a and 150b advantageously identical and mounted opposite, at equal distance by means of intermediate spacers 151 taken between the screws 147, 148 and 149; this cage 150
- the guide member may be a plate 152 taken from a material with a low coefficient of friction, for example silicone, embedded in the two lateral flanges 150a of the cage 150, slightly projecting in direction of the lateral faces of the branches 101 and 102.
- the guide member may consist of one or more rollers with a parallel axis (not shown in the figures), fixed in the thickness of the lateral flanges of the metal cage 150 to come to bear on the faces lateral branches following a generatrix perpendicular to the direction of their sliding.
- the improved tool 100 also allows total control of the discharge of the collar 1, even in a very environment crowded.
