Definitions

  • the present invention refers to the field of mechanical connections and relates to a fast lock and release device.
  • the present invention relates to a fast lock and release device that can be used to lock and release a tool.
  • the present invention can be advantageously applied to the field of machines for earth movement, demolitions and the like, and relates to a device quickly to lock a tool , like a bucket or the like, into, and to release it from, a working arm of a main operating machine, for example an excavator.
  • the Applicant has filed various patents applications relating to fast lock and release systems, each of which comprises an adapting member designed to be coupled to a mechanical tool in a rigid way, and a lock ad release unit designed to be coupled at the end of an arm of a working machine.
  • the adapting member and lock and release unit can be alternatively lock together and release from each other; this makes it possible to lock the tool in, and release it from, the arm of the working machine.
  • the adapting member has a seat to house the lock and release unit in a form-fitting manner; this seat is delimited laterally by two shoulders (transversally fastening the lock and release unit) and longitudinally by a pair of containment members.
  • one of these containment members is an axle, provided with at least one abutment for the end of a blocking member (movable or fixed according to the cases) of the lock and release unit.
  • Lock and release units are known, laterally delimited by two flanks, each of which is longitudinally delimited by a coupling member shaped like a longitudinally open hook to house an axle transversally; these flanks are connected to each other by means of a crossbeam at the side of the hooks and by means of a plate at the opposite side; according to the teachings of the Italian patent applications no. RA2014A000006 and RA2014A000007 filed by the Applicant, this plate has, at the top, a pair of abutment element to hold the axle vertically, so that, when the longitudinal blocking members move forwards, the lock and release unit stably refers to the same axle and, consequently, the adapting member and the lock and release unit are stably coupled.
  • each longitudinal blocking member operates exactly as a longitudinal key with respect to the respective axle, through a its surface, inclined relative to the movement direction, thus causing the correct coupling with the axle through the friction produced by the contact with the respective seat and the local deformation of the axle through the application of a transverse, and therefore bending, load.
  • each contact area between an axle and the surface delimiting internally the respective hook (provided in the corresponding flank of the lock and release unit) is arranged near the axle longitudinal ends; it should also be noted that the wider the longitudinal dimension of the axles grooves (open downwards) designed to couple through friction with the flat face (facing upwards) of the longitudinal blocking member, the more limited the longitudinal extension of this contact area.
  • the two grooves (open downwards) longitudinally communicate with each other, as they are part of a single longitudinal flattening, at the centre of which the central groove is provided.
  • the contact area between the axle peripheral portion and the respective support area provided in the hook (provided in the flank of the lock and release unit) is limited to longitudinal segments of the axle.
  • any removal of material in the outer part of a circular cross-section significantly concentrates the stresses and consequently reduces the resistance against shearing stress of the cross-section, in case the shearing stress exerted by at least one longitudinal blocking member (static of fatiguing) becomes significantly high (for instance, in case of prolonged wearing working cycles, like when using impact hammers or Ripper saws, or in case of works on rocks or highly resistant grounds) the axle resistance against shearing stress could be jeopardized.
  • static of fatiguing static of fatiguing
  • the coupling between lock and release unit and adapting member can be done only arranging the lock and release unit and the adapting member in a given reciprocal position, even if a greater versatility would be desirable; in particular, it would be desirable that the lock and release unit and the adapting member can be coupled together in more than one reciprocal position.
  • the present invention is based on the following consideration: the inconveniencies of the fast lock and release devices according to the prior art can be overcome or minimized by making the lock and release unit and/or the adapting member symmetric, thus having also the opportunity to couple them in at least two reciprocal positions, where one of them is rotated by 180°; as well as engaging the movable blocking members not in grooves of the respective fixed engagement members, but in holes or through apertures of said fixed engagement members.

  • said lock and release unit comprises two movable blocking members, each of which can be translated along said first translation direction in two opposite directions between a first forward, or lock, position and a second back, or releasing, position; wherein each of said two coupling axles may comprise two through holes for coupling said two movable blocking members, each of which extends in the respective axle according to a direction parallel to said first translation direction; and wherein said two axles are arranged and shaped so as to allow, by translating said blocking members towards said first lock position, the coupling of said blocking member in the coupling holes of one or the other axle according to the direction of said lock and release unit relative to said adapting member.
  • each of said blocking members may comprise a coupling head shaped like a flute reed, wherein each through hole for said one or two axles has a shape conjugated with, or corresponding to, the shape of said coupling head.
  • said coupling head of each movable blocking member may be delimited by an outer surface comprising a substantially flat inclined or tapered portion and a substantially curved portion connected to said substantially flat portion and inclined or tapered so that said coupling head has cross-section of decreasing width towards the end thereof.
  • said substantially curved portion can be substantially cylindrical or substantially conical.
  • said lock and release unit comprises a fixed blocking member arranged and shaped so as to couple, according to the direction of said lock and release unit relative to said adapting member, one or the other axle, especially the axle that is not coupled by said one or two movable blocking members.
  • said fixed blocking member may have a hook provided with a concavity designed to house at least one portion of each of said two axles, said concavity being delimited, for instance, by a substantially cylindrical respective surface portion designed to house said at least one portion of each said axle transversally.
  • said lock and release unit has two fixed blocking members arranged at a reciprocal distance from each other along a direction parallel to the extension direction of said two axles.

  • the present invention can be advantageously applied to the field of machines for earth movement, demolitions and the like, and relates to a device quickly to lock a tool, like a bucket or the like, into, and to release it from, a working arm or member of a main operating machine, for example, although without limitations, an excavator.
  • the device according to the invention will be described below with particular reference to the applications thereof for working machines of the above-mentioned type.

On the contrary, fall into the scope of protection of the invention also all the modifications and/or variants of the embodiments described and represented herein, that, based on the description above, will be apparent to those skilled in the art. The scope of the present invention is defined by the claims.
  • the device 1 comprises an adapting member 10 designed to be stably (and in releasable fashion, if necessary) coupled to a tool U, and a lock and release unit 20 designed to be stably (and in releasable fashion, if necessary) fixed to the handling member A and to engage, in use, the adapting member 10 in a respective central housing 11.
  • the housing 11 is delimited laterally by a pair of shoulders 12 extending along a given direction D, and transversally by at least one axle 14 connecting the two shoulders 12 together firmly.
  • each blocking member 22 has a tapered head 220 with increasing cross-section starting from a respective end 221.
  • Each axle 14 has at least one respective seat 140 (essentially a through hole or a blind hole, according to the needs and/or circumstances), which extends along the given direction D (it extends deeply in the axle 14 parallel to the direction D) and is aligned with the blocking member 22 for reciprocal coupling.
  • each seat 140 is arranged in front of the respective blocking member 22 and is delimited by a surface S (that can be closed or open, depending on whether it is through or blind), which is configured to house the end or coupling head 220 of the blocking member 22, completely surrounding it from the outside.
  • the lock and release unit 20 can be mechanical, actuated by means of a lever, or fluid-dynamic, comprising, for example although without limitations, a single-piece device already described with reference to the Italian patent application no. RA2014A00005 of the same Applicant. For the sake of practicality, the invention will be described herein with reference to this single-piece device, that will be briefly described below.
  • the lock and release unit 20 has a pair of flanks 202, each of which is designed to be arranged, in use, at the side of one shoulder 12, especially inside the space reciprocally delimited by the two shoulders 12.
  • Each flank 202 has a hook 204 (better shown in figures 4a and 4b ) provided with a longitudinally open concavity 205 designed to house an axle 14 (a transverse portion of the axle 14, see the description below) and delimited by a curved (for example substantially cylindrical, as shown) bottom surface portion 206, whose approximate angular extension corresponds to 180° and whose radius corresponds to, or is slightly greater than, the radial dimension of the axle 14.
  • the lock and release unit 20 comprises a box-shaped body 200 (better shown in figure 4a ) delimited by the flanks 202 and by a plate 26 arranged at opposite side from the box-shaped body 200 with respect to the hooks 204.
  • This plate 26 is delimited, towards the outside of the box-shaped body 200, by a substantially flat face or surface 26', and is provided with a through service hole 260 for each movable blocking member 22, wherein, when this blocking member is in forward, or lock, position P2 of figure 4b and engages the respective seat 140, the end or coupling head 220 of the blocking member 22 extends inside the box-shaped body 200 and through the respective through service hole 260, while, when the blocking member 22 is in back, or release, position P1 ( figure 4a ) and is released from the respective seat 140, the end or coupling head 220 of the blocking member 22 is housed substantially inside the box-shaped body 200.
  • the lock and release unit 20 comprises an actuating unit 24, for example fluid-dynamic, housed inside the box-shaped body 200 between the flanks 202 and the plate 26, to translate each blocking member 22 longitudinally between the back position P1 ( figure 4a ), where it is released from the corresponding axle 14, and the forward position P2 ( figure 4b ) where it locks the respective seat 140, through the respective service hole 260 of the plate 26.
  • the actuating unit 24 comprises a respective fluid-dynamic actuating member 241 (for example a valve) designed to control the movement of each blocking member 22 between the back position P1 and the lock position P2.
  • the actuating unit 24 of the lock and release unit 20 has centrally, in correspondence of the plate 26, one more hole 263 engaged by a switching member 261 to switch the actuating member 241 (for example a release valve, known and not shown, for lock and release the fluid-dynamic actuating unit 24).
  • This switching member 261 whose purpose is to switch the actuating member 241 (for example, to open the release valve), may be shaped similarly to a nut or in any other manner so that it can be driven into rotation or by thrust by means of an elongated tool, for instance a socket wrench, in case the fast and release unit 20 is in blocked condition, with the blocking members 22 engaging the seats 140 stably and the actuating unit 24 not working under the normal control, i.e.
  • the hole 142 allows, therefore, to access the control or switching member 261 and a rotation or a pressure or a traction applied, singularly or in combination (according to the respective mode of use) on the switching member 261 allows to release the actuating unit 24 and allows, in sequence, the blocking members 22 to elastically returned (in a known manner) to the respective positions P2 ( figure 4a ).
  • the adapting member 10 has two axles 14 that firmly connect the shoulders 12 together transversally and are arranged symmetrically and in a mirror-like fashion with respect to a transverse median plane M ( figure 3 ) of the adapting member 10 to make it reversible and to contain the corresponding lock and release unit stably.
  • each axle 14 has a pair of seats 140 arranged symmetrically at opposite sides with respect to a central service hole 142 provided in each axle 14 in a position facing the hole 263 of the plate 26 (housing the switching member 261).
  • Each hole 142 allows the passage of a tool or a control or switching instrument (like a socket wrench) for the switching member 261 or an inspection member.
  • each axle 14 has, at the bottom, a continuous longitudinal portion 143 extending continuously between the shoulder 12 transversally to each seat 140, to couple with the surface portion 206 of the hook 204 in longitudinally continuous fashion, thus allowing to maximize the area of contact and force exchange between the axle 14 coupled to the flanks 202.
  • the continuous longitudinal portion 143 acts as a contrast member for the deformation of the axle 14 due to shearing stress, considering the axle 14 a beam fixed to the shoulders 12 at end positions.
  • each seat 140 has a substantially flat upper portion S1 inclined downwards and a substantially cylindrical lower portion S2 facing the upper portion S1 and directed parallel to the direction D so that the surface S has cross-section of decreasing width towards the outside.
  • Figure 9 shows a detail of a longitudinal section of figure 1 , in correspondence of one of the hooks 204, where it can be seen that the lower portion S2 can be slightly flared towards the exit.
  • the head 220 is delimited by a substantially flat first face 222, designed to couple to the upper portion S1 in a form-fitting and substantially matching manner, and by a substantially cylindrical second face 224, designed to couple to the lower portion S2.
  • the coupling can be partial or form-fitting, according to the project specifications, obviously connected to the use of the device 1 and, anyway, always in order to allow the blocking members 22 to be extracted from the seat 140 by means of elastic, hydraulic or mechanical means, according to the nature of the lock and release unit 20.
  • each head 220 is shaped like a flute reed.
  • the lock and release device 1 can be easily understood from the description above. However, it should be useful to specify what follows, for the sake of clarity.
  • the hooks 204 are engaged on one axle so that longitudinal portions of the axle 14 are housed in the cavities 205 of the hooks 204.
  • the lock and release unit 20 rotates relative to the adapting member 10 (wherein the axle 14 acts as pivot) until the box-shaped body 200 of the lock and release unit 20 has been brought inside the space of the adapting member 10 defined by the shoulders 12, in particular until the holes 222 of the plate 26 have been brought in correspondence of the seats 140 of the second axle 14; in this way, the blocking members 22 are brought in correspondence of the engaging seat 140.
  • the blocking members 22 are switched, so as to translate from the back position P1 ( figure 4a ) to the forward position P2 ( figure 4b ), in particular until the coupling heads or ends of the blocking members 22 engage the respective seats 140 of the axle 14.
  • the fast lock and release device 1 solves the criticalities in operation of the known devices, making them more long-lasting and more practical to be used.
  • the fact that the fibres of the material of the axle 14 arranged in the plane of maximal shearing stress are continuous in correspondence of the respective diameter areas, in positions transverse to the directions of extension of the seats 140 due to the presence of the continuous longitudinal portion 143, allows to have axles 14 of greater strength and more resistant to shearing stresses above those normal during operation or following to technical failures of the actuating unit 24 of the longitudinal blocking members 22.
  • the device 1 is easily reversible and, thus, particularly versatile.
  • each blocking member 22 can be modified together with the respective seat 140 and replaced with a blocking member 22' and the respective seat 140' of conjugated shape in the length direction, for example giving the respective surfaces S1' and tapered head 220', originating from a respective end 221', a substantially identical conical shape, whose the respective longitudinal axis substantially parallel to the given direction D. Therefore, the conical surfaces S' and 225 are into reciprocal continuous conjugated contact.
  • figure 10 shows a rectangular track highlighting the presence of a front flattening provided in the axle 14 transversally to the given direction D.
  • This flattening graphically represented by means of a rectangular perimeter for the sake of drawing economy, has no reference number, as it has no utility for the understanding of the present invention.
