Description
REMOVABLE FAST-FIT HYDRAULIC FITTING FOR PLASTIC DUCTS
TECHNICAL FIELD
The present invention relates to a removable fast- fit hydraulic fitting for plastic ducts.
Though suitable for use in any hydraulic circuit, to connect a duct of plastic or other flexible material removably to a user device, the present invention is particularly advantageous for use in hydraulic circuits employing relatively small plastic ducts for conducting high-pressure fluid, e.g. water. BACKGROUND ART
In circuits of the above type, connection of a duct to a connecting conduit of a user device is normally made using a biconical bushing, which is fitted onto the end of the duct, is inserted inside a conical cavity formed in a hollow connecting member connectable directly to the connecting conduit of the user device, and is then locked inside the cavity by means of a nut having a conical seat inside.
By virtue of the conical connection between the bushing, the cavity, and the inner surface of the nut, the bushing is squeezed inside the cavity, when the nut is tightened on the hollow member, with sufficient axial and radial compressive force to cause the bushing to yield and, as it deforms, to grip the duct to form a fluidtight connection between the duct and cavity.
Though efficient and relatively easy to assemble,
this type of fitting has serious drawbacks in actual use, mainly on account of the relatively high cost, normally, of producing the conical surfaces necessary to clamp the duct and achieve a fluidtight connection, and the difficulties posed in particular when the fitting has to be removed and reassembled.
In fact, the bushing being locked inside the cavity by permanently deforming the bushing, reassembly of the fitting involves eliminating the end of the duct gripped by the deformed bushing, assembling another bushing, and, finally, locking the new bushing inside the hollow connecting member.
Moreover, since the bushing is normally locked inside the cavity by means of a nut screwed to a threaded portion of the hollow connecting member, assembly and removal of the fitting may prove awkward in particularly confined spaces with little room for manoeuvre. DISCLOSURE OF INVENTION
It is an object of the present invention to provide a removable fast-fit hydraulic fitting for plastic ducts, designed to eliminate the aforementioned drawbacks.
According to the present invention, there is provided a removable fast-fit hydraulic fitting for plastic ducts, as claimed in the accompanying Claims. BRIEF DESCRIPTION OF THE DRAWINGS
A non-limiting embodiment of the invention will be described by way of example with reference to the accompanying drawings, in which:
Figure 1 shows a view in perspective of a preferred embodiment of the hydraulic fitting according to the present invention;
Figure 2 shows a larger-scale axial section of the Figure 1 fitting;
Figure 3 shows an exploded view of the Figure 1 fitting;
Figure 4 shows a larger-scale view in perspective of a detail of the Figure 1 fitting. BEST MODE FOR CARRYING OUT THE INVENTION
Number 1 in Figure 1 indicates as a whole a fast-fit hydraulic fitting for removably connecting a plastic duct
2 to a hydraulic user device (not shown in Figure 1) and comprising a hollow body 3 connectable directly to the user device; an intermediate body defined by a cylindrical bushing 4 that can be locked permanently to the end of duct 2; and a lock bracket 5, which fits by means of a joint onto hollow body 3 to lock bushing 4 inside hollow body 3 and so form a stable connection between hollow body 3 and duct 2.
More specifically, as shown in Figure 1 and in more detail in Figures 2 and 3, hollow body 3 is substantially cylindrical, and comprises three portions aligned along an axis 6 : a central portion defined by a nut 7; a threaded cylindrical bottom portion 8 connected directly to a connecting conduit 9 (shown by the dash line in Figure 2) of the user device; and a cylindrical top portion 10 connected to nut 7 by a cylindrical portion
11, which is coaxial with axis 6, is smaller in diameter than nut.7 and top portion 10, and defines, with nut 7 and top portion 10, an annular groove 12 coaxial with axis β and forming part of the joint connecting bracket 5 to hollow body 3, as explained in detail below.
Inside, hollow body 3 has a through hole 13 coaxial with axis 6 and comprising a first portion, which extends substantially along bottom portion 8 and is smaller in diameter than the outside diameter of duct 2; and a second portion, which has a diameter substantially equal to the outside diameter of duct 2, and, at the end communicating with the outside, a wider portion defining a cylindrical cavity 14 coaxial with axis 6 and for housing bushing 4 in use. As shown in Figures 2 and 3, bushing 4 comprises a ring 15 with an inside diameter approximately equal to but no smaller than the outside diameter of duct 2, and an outside diameter approximately equal to but no larger than the diameter of cavity 14. At one end, ring 15 is connected to a coaxial cylindrical appendix 16 having an outside diameter smaller than the outside diameter of ring 15, and which, in use, after bushing 4 is fitted to duct 2 and before bushing 4 is inserted inside cavity 14, is tightened about duct 2 so as to undergo permanent deformation, form a local constriction (Figure 3) in duct 2, and so make bushing 4 integral with duct 2.
Lock bracket 5 is substantially double-C-shaped, and comprises a substantially rectangular major lateral wall
17, and two rectangular minor lateral walls 18 facing each other and perpendicular to major lateral wall 17.
A cavity 19 is formed on one short side of major lateral wall 17, extends along the centreline of major lateral wall 17 in a direction parallel to lateral walls
18, and is bounded by two flat parallel surfaces spaced apart by a distance approximately equal to but no smaller than the diameter of duct 2, and connected to one another by a semicircular end surface. On the short side opposite the one in which cavity 19 is formed, major lateral wall 17 is connected to a substantially rectangular tab 20 projecting upwards and which, in use, serves to facilitate assembly and removal of bracket 5 by the user. As shown in Figure 4, minor lateral walls 18 are connected to respective identical appendixes 21, each of which extends parallel to major lateral wall 17 towards the centre of bracket 5 and towards the other appendix 21, and is shaped to define, with the other appendix 21, a substantially circular opening 22 open on two opposite sides, of substantially the same diameter as cylindrical portion 11, and having an outwardly-flaring inlet 23 on the open side corresponding to the side of major lateral wall 17 on which cavity 19 is formed. Finally, as shown in Figure 2, the distance between major lateral wall 17 and appendixes 21 substantially equals the height of top portion 10 of hollow body 3, measured parallel to axis 6.
In actual use, once hollow body 3 is fitted, with the interposition of a sealing ring 24, to connecting conduit 9 of the user device, and bushing 4 is pinched onto the end of duct 2, bushing 4 is inserted inside cavity 14 with the interposition of an annular seal 25 on the bottom of cavity 14, and of a washer 26.
In connection with the above, it should be pointed out that, when fitting bushing 4 to duct 2, the user must take into account the length of "the portion of duct 2 projecting beyond bushing 4, so that said portion is long enough to fit at least partly inside hole 13 beyond cavity 14, but is also short enough so that, once inserted, bushing 4 projects only slightly outwards of top portion 10. At this point, once bushing 4 and the end portion of duct 2 are assembled inside hollow body 3, the bushing is locked inside cavity 14 by the user, who grips bracket 5, positions it on a level with top portion 10 so that appendixes 21 are aligned with annular groove 12, and pushes bracket 5 against hollow body 3, in a direction perpendicular to axis 6, with sufficient force to flex inlet 23 outwards by contrast with cylindrical portion 11 and so force cylindrical portion 11 through inlet 23 into opening 22. Once the largest-diameter section of cylindrical portion 11 has been forced through inlet 23, inlet 23 snaps back about cylindrical portion 11, which is thus "locked" inside opening 22, locking bracket 5 in the
position shown in Figures 1 and 2.
As regards assembly of bracket 5, it should be pointed out that, during initial insertion of bracket 5 into the "locked" position, the central part of major lateral wall 17 intercepts the portion of bushing 4 projecting slightly from cavity 14. And, as bracket 5 moves gradually forward, major lateral wall 17, sliding over top portion 10, allows duct 2 through into cavity 19, and compresses bushing 4 axially, so as to indirectly compress annular seal 25 on the bottom of cavity 14 and so form a fluidtight connection between bushing 4 and hole 13.
Cavity 19, as stated, being substantially the same size as duct 2, bushing 4, once bracket 5 is inserted, is locked axially inside cavity 14 by contrast with major lateral wall 17 contacting the surface of top portion 10 surrounding the free edge of cavity 14.
The fitting can be removed, at this point, by simply performing the assembly operation of bracket 5 in reverse, i.e. pulling bracket 5 in a direction perpendicular to axis 6 by means of tab 20, so as to gradually flex inlet 23 outwards by contrast with cylindrical portion 11 until cylindrical portion 11 is fully withdrawn from opening 22, thus detaching bracket 5 from hollow body 3 and opening cavity 14, from which bushing 4 and duct 2 can then be extracted.
In a variation, not shown, of fitting 1 according to the present invention, fitting 1 is "double" and used to
connect two plastic ducts to each other. In which case, as opposed to threaded bottom portion 8, hollow body 3 has a bottom portion similar to top portion 10 and having a cavity similar to and opposite cavity 14 to house a respective bushing similar to bushing 4.
The inside diameter of the second cavity and/or the inside diameter of the second bushing may, of course, be the same as or different from the inside diameter of cavity 14 and bushing 4 respectively, depending on whether the two ducts being connected have the same or different outside diameters. The operating principle of the "double" fitting, however, remains identical to that of fitting 1 described above.
To conclude, it should be pointed out that, besides being extremely fast and easy to use, the fitting according to the present invention is equally fast and easy to reassemble if necessary. That is, the fact that bushing 4, once fitted to duct 2, undergoes no permanent deformation when being locked inside cavity 14, and is retained inside cavity 14 solely by contrast with bracket 5, the bushing need not be replaced with a new one, and the fitting can be reassembled by simply reinserting bushing 4 inside cavity 14, and reassembling bracket 5 as described above.
