Definitions

  • the present invention relates to an assembly for the rapid coupling of two elements, in particular of a member of a family of hand tools or instruments, to a versatile handle.
  • These may in particular be gardening tools.
  • the invention relates to an assembly for the rapid coupling of two elements, one of which comprises a male part and the other a female part, said male part having a circular bore capable of receiving a temporary assembly member. depending on the female part, said bore being connected to the free end of said male part by a through cutout.
  • This type of assembly has the disadvantage that there is always a risk of relative axial displacement between the male and female elements as a result of the inevitable play between the parts.
  • the object of the present invention is to remedy this drawback.
  • This object is achieved in the sense that, as a whole it offers, an eccentricity is created between at least part of the temporary assembly member and the axis of symmetry of the bore.
  • the cavity of the female part and the male part are substantially of the same rectangular section.
  • the temporary assembly member is a member movable in rotation comprising a key in the portion of a cylinder which depends on an axis.
  • One end of said axis turns in a blind hole made, from the cavity of the female part, in the thickness of the latter and means are provided to prevent said axis from detaching from the female element.
  • a piece of elastic synthetic material interposed between the bottom of said blind hole and the end of the axis opposite to the operating member, exerts a thrust on said end.
  • stop means are provided which authorize the rotation of the axis and its key only over a quarter turn.
  • the temporary assembly member is a member movable in translation comprising a key depending on a rod of a length greater than the thickness of the female part and transversely crossing said part female right through, said rod having a cross section such that it can pass through said cutout, and said rod being capable of being moved between an unlocking position for which the key is set back from the cavity, and a position for which the key is located in said cavity.
  • the key is frustoconical and of an average diameter close to that of the bore of the male part and, in the unlocked position, the frustoconical key is received in a housing provided in the thickness of the female part, directly above the position occupied by the drilling of the male part when the two parts are coupled.
  • the female part is advantageously formed from a block or two half-blocks of hard synthetic material included in a steel tube, the cavity adapted to receive the male element being formed in said block or said half-blocks.
  • the blind hole may be a hole which opens into said cavity of the female part and outside the female part, this hole being made blind by said tube in which the female part is included.
  • a sleeve in two parts 1a, 1b, of hard synthetic material, hooped in a constricted tube 2 of steel.
  • the sleeve 1a, 1b could be in one piece and / or be immobilized in another way with respect to the tube 2, for example be fitted into said tube and immobilized using fixing screws.
  • the sleeve 1a, 1b, of rectangular section comprises a rectangular cavity 11 adapted to guide and receive the tang 3 of a tool.
  • the tang 3 has a rectangular section very close to that of the cavity 11 and it comprises, on the side of its free end, a circular hole 4 which is connected to the free end 5 of the tang 3 by a through cutout 6.
  • the sleeve has a passage 7 in which the support part 8 is forcibly fitted with an operating button 9 made of synthetic material.
  • this support part 8 is secured a pin 10 of steel or hard plastic which carries at the level of the cavity 11 a key 12 in cylinder portion. More specifically, this cylinder portion comes from a cylinder whose radius is substantially equal to that of the bore 4 and from two flats 13a, 13b. The distance between the flats 13a, 13b is very slightly less than the width of the cutout 6, so that when the key 12 occupies the position shown in FIG.
  • the tang 3 can be extracted from the sleeve 1a, 1b, the key 12 sliding through the cutout 6.
  • the key 12 occupies the position shown in FIG. 1, it opposes the axial displacement of the tang 3.
  • the axis 10 rotates in a blind hole 14 formed in the part 1b of the sleeve and a block of flexible and elastic synthetic material 15 is interposed between the free end of the axis 10 and the bottom of the blind hole 14.
  • means are provided to prevent the separation of the button 9 and its axis 10 from the tube 2 / sleeve 1a, 1b assembly, for example a clip system on the part of the support 8 which is located inside part 1a of the sleeve and which abuts against the internal face of the tube 2.
  • the axis 10 being thus immobilized, the block of elastic material 15 exerts a thrust against its free end, which thrust brakes the rotational movement of the axis 10. In this way, the key 12 does not risk spontaneously passing from the position of Figure 1 to the position of Figure 2, which would cause untimely separation of the tool and handle.
  • a marker system is provided on the button 9 and / or the outside face of the tube 2 so that the user knows, without fumbling, if the key inside the sleeve 1a, 1b is in the position of the Figure 1 or in the position of Figure 2.
  • stop means not shown, which allow the rotation of the axis 10 and its key 12 only on 1/4 turn .
  • buttons-support 8.9, axis 10 and key 12” assembly could be in one piece.
  • the part of the axis 10 rotating in the blind hole 14 is eccentric with respect to the axis of symmetry of the bore 4. This results in a wedging effect which remedies the play very small but However inevitable between parts and avoids any relative axial movement between the tool and the handle. A positive immobilization of the silk 3 is thus obtained in the sleeve 1a, 1b.
  • the blind hole 14 could be given a non-circular shape providing the desired eccentricity.
  • the tube 2 and the sleeve 1a, 1b are traversed right through by a passage 16 intersecting with the cavity 11.
  • This passage 16 has an enlarged zone forming housing 17 and determining a shoulder 18.
  • the passage 16 and the housing 17 are adapted to receive a cylindrical rod 19 on which is mounted a frustoconical key 12 ′.
  • the rod 19 is of a diameter slightly smaller than that of the through cutout 6 while the key 12 ′ has an average diameter close to that of the bore 4 provided in the tang 3.
  • the axis 19 slides with a slight tightening in the passage 16.
  • the axis 19 and its frusto-conical key 12 ′ are thus capable of occupying two positions, namely a locking position illustrated in FIG.
  • the part 19b of the axis 19 is eccentric with respect to the part 19a of the said axis and to the key 12 ′.
  • the two ends 20a and 20b of the axis 19 project out of the tube 2, the release being obtained by striking on the end 20b according to the arrow F1, and the blocking on the end 20a according to arrow F2.
  • the coupling system according to the invention overcomes the drawbacks of the previously known techniques in the sense that it is more reliable and that the assembly and disassembly require neither technicality on the part of the user or the use of a tool (rarely handy at the gardening site).
  • the present invention is not limited to the forms of execution described and shown. In particular, it is applicable to the rapid coupling of elements other than a tool handle to a family of tools, for example to the coupling of a handle common to a projection provided on each of the members of a family of containers, thus replacing the known systems for removable mounting, for example of stove tails.
  • the assembly according to the invention is, for example, also applicable to the rapid coupling of elements such as mast elements for the production of modular furniture.
