Definitions
- the present invention relates to a device for coupling a part of a male part with a part of a female part provided with a recess of lock, of the type described in the preamble to the claim 1.
- the invention applies in particular to coupling between a tool extension or cardan joint rotary drive, for example ratchet, and another extension, an interchangeable socket or a gimbal for screwing / unscrewing.
- the actuator is a sliding ring mounted on the male part and directly connected to the transmission means, formed by a central rod, by a pin transverse.
- the pin goes through a slot diameter of the male part which must be sufficiently long and wide, which considerably weakens the male part.
- the invention aims to provide a device more robust coupling than these devices known, while being reliable, comfortable to use and unlikely to clog.
- the subject of the invention is a coupling device of the aforementioned type, characterized by the characterizing part of claim 1.
- the following coupling device the invention may additionally include one or more of the characteristics of claims 2 to 14.
- the invention also relates to a tool rotational drive, including a rigid extension or flexible, a gimbal, an articulated or sliding handle or a crankshaft, comprising a part of a part male whose distal end part is intended for fit into a female part of an organ drive, including a socket, a cardan or a rigid or flexible extension, provided with a recess locking part, the male part part comprising a coupling device as defined above.
- Extension 1 shown in Figures 1 and 2 has the general shape of a straight bar of axis X-X, assumed to be horizontal for convenience of description.
- This extension is intended to cooperate, by its end proximal or rear (right on Figures 1 and 2), with a tip 2 of a rotary drive tool 3, which is for example a ratchet wrench.
- Tip 2 can particular be a normalized square and is received in a axial conjugate hole 4 of the extension.
- a ball 5 of the tip loaded by a spring, then snaps in a corresponding recess provided in hole 4.
- the extension At its distal or forward end (left in the drawing), the extension has a male profile coupling 6 non-circular and is provided with a coupling device 7.
- Profile 6 is suitable for fit into a conjugate female profile provided in the proximal end of an interchangeable socket 8.
- the distal end of the latter has a profile adapted to cooperate with the head of a organ to be driven in rotation, which is typically a screw or nut.
- the locking device 7 ( Figures 3 and 4) is constituted in the following manner.
- a blind central stepped bore A is provided along the X-X axis from the distal end of the extension. It successively includes an entrance part 9 of large diameter, an intermediate part 10 of medium diameter, and a main part 11 of small diameter and greater length, ending well beyond part 6 of the extension.
- a first radial duct 12 connects the part intermediate 10 of bore A on the surface of the extends and opens into a hollow region of the profile 6.
- the outer opening of this conduit 12 is narrowed.
- the conduit 13 is counter-bored approximately to the length, which defines an internal shoulder 14.
- An actuator 15 is pivotally mounted in the conduit 13. It includes a spherical ball joint 16 held between the shoulder 14 and an outer bead of crimping 17 made at the entrance to the conduit.
- the kneecap 16 extends outwards by an operating button 18, projecting from the outer surface of the extension, and inward by a tail 19, which enters the bore part 11.
- the diameter of tail 19 is slightly lower than that of this part 11.
- a central transmission rod T is received in bore A. It is made up, from back to the front, of a main body 20 sliding in the part of bore 11, of an unlocking section 21 of small diameter, of a first frustoconical cam 22 flaring forward, of a locking section 23 of intermediate diameter, of a second frustoconical cam 24 also flaring forward, and an axial stud 25 of small diameter.
- a cup 26 is fixed in the part inlet 9 of the bore, and a return spring 27 is compressed between the bottom of this cup and the end before the rod T, the stud 25 ensuring the centering of the spring.
- a locking ball 28 is housed with a small clearance in the conduit 12 and is retained in this by the aforementioned narrowing of its opening.
- a recess 8A for example formed by a torus groove as shown in phantom in Figure 3, is located opposite the duct 12.
- the spring 27 is then allowed to return the central rod T to its initial position, this which brings out the ball 28 under the action of the cams 22 then 24, the ball consequently being housed in the recess 8A in the socket.
- the coupling is then Locked.
- the actuator 15 is substantially guided laterally, so its movement is practically limited to forward-backward pitch in the common plane of conduits 12 and 13.
- the variations in radial clearance between the socket and the extension, as well as the variations depth of the recess 8A, are automatically compensated by the presence of cam 24 and the spring 27, which permanently exercise solicitation elastic of the ball radially outwards.
- the locking position of the device 7 is therefore practically identical to its rest position.
- the orifice biconical 32 provides lateral guidance of itself the actuator, while making it possible to obtain a displacement increased axial of the central rod and eliminating any play between the actuator and this rod, whatever the direction of displacement.
- the assembly 43-47 is pushed forward by the spring 49, so that the actuator 15 is tilted towards the front.
- the retraction of the ball is obtained by pulling back the ring body 43, which compresses the spring 49 via ring 47.
- the ring 40 is protected against accidental unlocking by the socket itself, which has at least an outside diameter equal to that of this ring.
- Circlips 45 contributes also to this protection.
- the big diameter of the return spring 49 provides a large locking reliability.
- Figures 16 and 17 constitutes a variant of that of FIGS. 5 to 7, of which it differs in the arrangement of the actuator. Indeed, the radially inner half of the ball joint 16 is removed, and the remaining half-ball joint is biased towards the outside by an auxiliary spring 39.
- Figures 18 to 20 illustrate the application of the invention to a universal joint whose male part 1A is articulated, via a crosspiece 1B, to the female part 1C gimbal.
- the male part 1A comprises a body 60 which is ends with the male coupling profile 6.
- the bore central A runs right through the body and is counter-bored at 61 from its proximal end to a short distance from the distal radial duct 12 which receives the ball 28.
- the body 60 ends in a face 62 roughly transverse to the axis X-X and slightly concave, on which two protrude ears 63 connected to the crosspiece 1B.
- the central rod T is similar to that of Figures 14 and 15, except that its proximal end is full and provided with an extra thickness 64 which slides in the overbore 61.
- the return spring 27 is compressed between this extra thickness and the bottom shoulder overbore.
- the rocker 15 has a button 18 direct actuation as in Figures 1 to 7. Its ball joint 16 is held against the shoulder 14 of the radial duct proximal 13 by a forked end branch 67 of a fixed bracket 68 in the general shape of C.
- the core 69 of this stirrup follows face 62 of body 60 and is guided laterally between the internal, flat and parallel faces to the X-X axis and between them, the two ears 63.
- the two end branches 67 and 70 of the stirrup snap into opposite recesses 71 of the body 60, each provided with an overhanging projection 72 at their proximal end.
- the notch 73 of the fork 67 has a shape in U with two parallel edges and laterally guides the button 18, which is cylindrical.
- the rocker 15 has a single degree of freedom, rotating around the axis of the ball joint 16 which is perpendicular to the axis X-X.
- FIG. 21 to 23 differs from the previous by the fact that the stirrup 68 goes around the body 60. It has a flat core 80 provided with a hole oblong 81 which laterally guides the cylindrical button 18, this core 80 being applied to a flat face 82 of body 60.
- the legs of the stirrup are positioned by lateral recesses 83 of the body 60, in which they are received.
- the free ends of these branches apply to a flat face 84 of the body 60 opposite on face 82.
- a plug 85 closes the proximal end of the overbore 61.
- the socket 8 can be replaced by any other body or tool with a similar female part, for example for example by a universal joint or by an extension (rigid or flexible).
- extension 1 can be understood replaced by any other body or tool with a similar male part, in particular by a universal joint, by a extension (rigid or flexible), by an articulated handle, by a crankshaft or by a sliding handle.
