Definitions
- the present invention relates to a clamp for connecting two tubes, the opposite ends of which have bearing surfaces projecting from the cylindrical outer surface of said tubes, the collar comprising two half-shells each having a first end provided a support tab which extends outwards and has a hole, as well as a second end provided with one of the elements of assembly means intended to removably assemble said second ends of the half shells, said half-shells having, in their main part, a substantially U-shaped section, the branches of which extend inwards and are able to cooperate with said bearing surfaces of the two tubes, the collar comprising a clamping screw, able to cooperate with the support legs and whose rod passes through the holes of the latter.
- the operator having to handle the collar must therefore have three separate parts, namely the two half-shells assembled together, the screw and the nut. So finally it must assemble these three parts, which can be the cause of some loss of time, especially since relatively small parts such as the screw or nut may escape and fall on the ground.
- the collars are delivered in the pre-assembled state in which the screw and nut are already in place. The operation consisting in installing the collar must be preceded by unscrewing the nut and / or releasing the screw outside the holes in the support legs.
- Document GB-A-2 094 385 shows another collar of the aforementioned type, the means for assembling the two half-shells comprising a tab provided with a slot in which another tab engages.
- the assembly means are presented as a means of limiting the number of pieces of the collar.
- GB-A-2 094 385 does not specify the method of mounting the collar around the object to be tightened, but it seems that the only possible mounting method is the same as that of the collars of US-A-3 014 259 and US-A-3,964,773.
- a length of rod between one and two times the radius of the collar in the tight state combined with a play of a few tenths of a millimeter at 1 or 2mm from the rod in the bores allows the establishment of the collar without remove the screw. It should be noted that, to avoid that the tightening of the nut requires a large number of turns, it is preferable to ensure that the length of the rod is at most of the order of one and a half times the radius of the collar in the tight state.
- the assembly means comprise a first ear, located at the second end of a first half-shell, projecting radially outward radially from the outer periphery of said first half-shell and having a free end curved inward to form a hook, as well as a second ear, located at the second end of the second half-shell, projecting substantially radially outwards from the external periphery of said second half-shell and able to cooperate with said hook.
- FIG. 2 is a partial view along arrow II of FIG. 1
- FIG. 3 is a section along the line III-III of FIG. 1
- FIG. 4 is a partial view along arrow IV of FIG. 1,
- FIG. 9 is a view similar to FIG. 1, showing a variant of the collar
- FIG. 10 is a partial section along the line X-X in FIG. 9, and
- FIG. 11 is a section along line XI-XI of Figure 10.
- the collar of FIG. 1 comprises two half-shells 10 and 20 which each have a first end provided with a support lug, respectively 12 and 22, as well as a second end provided with an assembly element, respectively 14 and 24.
- the elements 14 and 24 constitute assembly means which make it possible to removably assemble the second ends of the half-shells 10 and 20.
- the support legs 12 and 22 extend towards the outside of the necklace, that is to say they move away from the center of the collar from the current periphery of the latter.
- the two legs 12 and 22 are parallel and extend generally in a radial plane of the collar.
- the rod 32 of a screw 30 passes through two aligned bores 12 'and 14', respectively formed in the support tabs 12 and 22.
- the two half-shells are made from a metal strip wound on substantially 1/2 turn and suitably hardened.
- the second ends of the half-shells 10 and 20 are assembled by means of assembly elements 14 and 24 and the nut 34 for tightening the screw is actuated so as to bring one of the other the two support legs 12 and 22.
- the head 36 of the screw cooperates with one of the support legs (12) while its nut 34 cooperates, directly or indirectly, with the other support leg (22).
- a washer 38 is fixed to the support tab 22, the end 38a of this washer which is opposite to the support tab 12 serving as a stop for the nut during tightening.
- this washer is simply engaged in the bore 14 'of the tab 22 and is riveted to the latter by deformation of its end 38b opposite the end 38a above.
- the connecting element 14 forms a first ear which is situated at the second end of one of the half-shells (10). This first ear projects radially outwards from the collar from the external periphery of this half-shell and has a free end 14a which is curved inwards to form a hook.
- the connecting element 24 forms a second ear which is situated at the second end of the other half-shell (20), which projects substantially radially outwards from the external periphery of this second shell and which is able to cooperate with the hook 14a by engaging in the hollow of the latter.
- the two ears 14 and 24 are located in radial projection relative to the current periphery of the collar.
- the height h of the ear 24, measured from the free edge of the hook (engagement height), is low, conventionally of the order of 2 to 5 mm, so that the hook 14 can be engaged on the ear without it being necessary to move the half-shell 10 too far towards the outside of the collar relative to the half-shell 20.
- the width I of the bottom of the hook is greater than the thickness e of ear 24 (substantially equal to one and a half times this thickness) to allow easy engagement of the ear 24 in the hook 14a by a relative inclination of the two half-shells.
- the assembly means function as a hinge around which the half-shells pivot when the nut is tightened on the screw.
- the main parts of the half-shells have a substantially U-shaped section having a bottom 40 and two branches 41 and 42.
- the lines are also shown in fine lines. ends of two tubes 44 and 46 provided with bulges 44a and 46a on which are placed the half-shells of the collar. More specifically, the bulges comprise bearing surfaces, respectively 44b and 46b with which the branches 41 and 42 of the U which cooperate form the section of the half-shells so as to clamp the tubes tightly against one another .
- the bearing surfaces 44b and 46b are in fact advantageously frustoconical, as are the branches 41 and 42, so that the tightening of the collar effectively tends to bring the two tubes closer to one another.
- the section of the half-shells has the overall shape of a U
- the flat part 40 forming the base of the U, and delimiting the external periphery of the collar, can be more or less long depending on the dimensions of these bulges. It can even be practically non-existent, in which case the section of the necklace would rather have the shape of a V.
- the partial view of Figure 2 shows that the ears 14 and 24 are formed by deformations of the ends of the half-shells, for example obtained by stamping. These are raised radially; the cheeks 16 and 18 are also raised and contribute to the formation of the ears.
- a screw constituted by a simple threaded rod tightened by means of two nuts cooperating respectively with each of the support legs 12 and 22.
- a screw whose head 36 is integral with the rod, only the nut 34 to be manipulated for tightening.
- the support tab 12 which cooperates with the head 36 of the screw is advantageously equipped with means to prevent the rotation of the latter.
- the head of the screw has at least one flat 36a (for example, quite simply a polygonal head is chosen).
- the support tab 12 with which the head of the screw cooperates has a flange 12a which extends in the direction away from the other support flap 22.
- This flange defines a housing 13 for the head 36 of the screw (it extends for example over a length slightly greater than the thickness of this head).
- the rim 12a On at least part of its contour, the rim 12a has a substantially flat portion 13a, able to cooperate with the aforementioned flat 36a.
- the rim in its part farthest from the current external periphery of the collar, with a similar polygonal shape whose sides are slightly longer than those of the screw, so as to preserve a slight clearance f between the head of the screw and the flange.
- the head 36 is not completely blocked, which, as will be seen below, allows a slight relative movement of the screw and the tab 12, but the head of the screw cannot rotate inside. of the housing 13.
- the latter advantageously has a wall element 15 which partially closes it on the side opposite to the support tab 22.
- This wall element 15, constituted for example by an extension of the rim 12a folded substantially at a right angle, is produced so as not to prevent the relative movement of the screw and the support tab 12.
- the rim 12a of the lug 12, as well as a similar rim 22a of the lug 22, also constitute means for stiffening these lugs preventing their folding when the collar is tightened.
- the internal periphery of the washer 38 is frustoconical and widens towards its end 38a. The angular movement of the two half-shells relative to the rod of the screw according to F1 and F2 necessary for attachment depends on the height of the branches 41 and 42 of the U (FIG. 3) and, more precisely, on the height of overlap between branches 41 and 42, and the bulges
- the second half-shell is folded down (in this case, the half-shell 10) to bring it back into the plane of the first (20).
- the second end of the half-shell 10 passes without difficulty the obstacle constituted by the tubes and their bulges, thanks to the fact that the length of the rod is sufficient.
- the two half-shells 1 10 and 120 have a U-shaped section, the branches of which have edges 1 10a, 120a slightly raised to extend axially, as shown in FIG. 1 1 for the half-shell 1 10.
- the support legs 112 and 122 are reinforced by flanges or cheeks 112a, 122a which extend in the continuity of the branches of the U formed by the sections of the half-shells, without reversing these branches unlike the flanges 12a and 22a of Figure 1. Therefore, in Figure 9, the head 136 of the screw 130 is not disposed in a housing.
- the region of the rod 132 of the screw immediately adjacent to the head 136 has a non-circular collar 133 (for example a square collar or a bead having a flat) and the hole 112 'has a shape with which this collar can come into engagement.
- the hole 112 ' is slightly larger than the collar 133 so that the play j1 is preserved between the rod of the screw and the edges of the hole 114'.
