Definitions

  • the invention relates to a deposit device and to a built-in cart comprising such a device.
  • transport carts of the built-in type made available to users in self-service stores, railway stations, airports and other public places.
  • These trolleys are provided with a permanently fixed control unit capable of receiving a coupling member of a neighboring trolley when these trolleys are embedded one in the other.
  • the uncoupling of these carriages is carried out by introducing a coin of predetermined type into a coin operated system which can be actuated so as to release the coupling member and to embed the carriage of the following carriage.
  • US Patent 4,691,816 describes a lockout device for a carriage comprising a body constituted by a sliding drawer in a housing against a return spring in the open position.
  • the drawer has a housing for a coin of a predetermined type, while the housing has a lock for a key.
  • the drawer slides substantially perpendicular to the direction of insertion of the key into a slot in the housing.
  • This device is generally satisfactory in normal use but is subject to break-ins resulting from the introduction of tools into the housing intended for the coin and the wrenching of the key. In this way, these known type carts can be released without prior deposit of a coin in the corresponding housing and can be damaged or stolen.
  • the object of the invention is to remedy the aforementioned drawbacks, by creating a new locking device having greater safety and reliability than those of the prior art, as well as economical manufacture.
  • the subject of the invention is a deposit device, in particular for a trolley, comprising a drawer sliding in a box against a return spring, the drawer comprising a housing for a deposit piece of predetermined type, the box comprising a lock for a key or similar coupling member and the sliding drawer substantially perpendicular to the direction of insertion of the key into a slot in the housing, characterized in that a latching member secured to the housing retains the drawer in a position stable intermediary in which the key and the drawer are simultaneously prisoners of the case.
  • the invention also relates to a built-in trolley comprising a device fixed to the push bar of the trolley, characterized in that the sliding direction of the drawer is parallel to the longitudinal axis of the trolley bar and in that the direction of introduction of the key is substantially perpendicular to said longitudinal axis.
  • a device comprises a drawer 1 sliding in a housing 2 adapted to receive a key 3 in a slot of corresponding shape.
  • the drawer 1 is mounted captive in the housing 2 and is held in the open position by a spring 4 working in compression between two corresponding faces of the drawer 1 and of the housing 2 respectively.
  • the drawer 1 has a housing 5 corresponding to a lockout piece of predetermined type.
  • the drawer comprises for example a bar 6 for holding the part in its housing 5, an end boss 7, a slot 29 corresponding substantially to a diameter of the housing 5 of essentially cylindrical shape, an end member 9 disposed internally at the box 2 when the drawer is assembled to the box;
  • the housing 2 also includes a latch 10 held in the key locking position 3 by a spring 11 as well as possibly an ejector 12 consisting for example of a key ejection spring disposed under the end of the key when the key 3 is locked in the housing.
  • a latch 10 held in the key locking position 3 by a spring 11 as well as possibly an ejector 12 consisting for example of a key ejection spring disposed under the end of the key when the key 3 is locked in the housing.
  • an end member 9 secured to the drawer 1 produced, for example directly by machining the latter, comprises a latching housing 13 limited by a retaining spout 14.
  • the member 9 comprises two lugs 15 and 16 in relief relative to the spout 14 and the arm 17 connecting the member 9 to the drawer 1 and to the housing 5.
  • the lug 15 is limited by a first inclined plane 18 or similar surface bearing a slope inclined at an acute angle relative to the direction of insertion of the key, as well as another inclined plane 19 forming a predetermined angle as a function of the diameter of the housing 5 of the deposit coin.
  • the inclined plane 19 is extended by a concave surface 20 which also limits the lug 16 constituting an additional protuberance with respect to the lug 15.
  • the lug 16 is limited by two planes 21 and 22: the plane 21 is substantially parallel to the direction of insertion of the key 3 and the plane 22 is substantially parallel to the direction of sliding of the drawer 1 in the housing 2.
  • the invention preferably relates to devices in which the direction of sliding of the drawer 1 in the housing 2 is substantially perpendicular to the direction of insertion of the key 3 in the housing 2, but it is understood that the invention s 'also applies in the case of non-perpendicularity with obvious modifications to the skilled person.
  • FIG 4 there is shown schematically a device according to the invention comprising identical or similar elements and identified by numbers identical to those of Figures 1 to 3B.
  • a latching member 23 is held in position by a return spring 24 working for example in elongation, so that the latching member 23 pivots about an axis 25 integral with the housing on which it is threaded by means of the corresponding bore in Figure 5.
  • end pins 26 and 27 cams or similar rollers, are attached to the latching member 23, or else made from a single piece, for example directly machined in the same draft.
  • the lock 10 held in the key locking position by the spring 11 is extended by a notch 28 corresponding to the insertion into the light 29 opening into the housing 5 of the deposit piece.
  • the key 3 has two perpendicular wings 30 and 31.
  • the wing 30 cooperates with the latch 10 by means of an inclined plane of engagement 32 capable of pushing the latch 10 until it engages under the pressure of the spring 11 in the housing 33 corresponding to the thickness of the latch 10.
  • the lateral face 34 is substantially flat and parallel to the direction of insertion of the key.
  • the plane 35 of the inner wing 31 at the right angle formed by the two wings 30 and 31 cooperates with the inclined slope 18 of the member 9 of the drawer 1 to push this drawer towards the interior of the housing 2.
  • the wing 31 is indented in its thickness by openings limited by planes substantially parallel to the direction of sliding of the drawer 1 in the housing 2: the first plane 36 cooperates with the stud 27 of the latching member 23 to push this latching member downwards by pivoting it against the return spring 24, the plane 37 corresponds to the retention of the key in an intermediate position in which the drawer and the key are simultaneously trapped, the key being retained by pressing the plane 37 on the substantially planar extension 20a of the concave surface 20 of FIG. 3b.
  • the plane 37 also cooperates with the stud 27 of the latching member 23 to retain the key 3 in the housing 2 in another intermediate position described below.
  • the substantially L-shaped recess 38 corresponds to the passage of the end member 9 through the key.
  • the drawer 1 is held in the open position by the spring 4, while the key 3 is retained by the latch 10 supported by the spring 11 in the housing 33, the ejector 12, bearing on the lower end 39 ( Figure 6) of the key, not being shown.
  • the stud 26 of the latching member 23 is held in the low position by the spring 24: if the drawer 1 is pushed in the closing direction, the end and the stud 26 of the latching member 23 abut against the boss 7 of the drawer 1 thereby constituting a translation stop on closing in the absence of a deposit or in the presence of a part not conforming to the required type.
  • the stud 26 of the latching member 23 follows the outer contour of the locking piece raising the end 26, so that the stud 27 and the corresponding end pass through the notches of the wing 31 of the key 3, the stud 27 first of all following the inclined plane 19 of predetermined slope as a function of the diameter of the consignment piece, then the concave surface 20 thereby enveloping the outer contour of the end member 9 of the drawer 1.
  • the stud 27 reaches a low position corresponding to the highest position of the stud 26 on the contour of the deposit piece.
  • the latching member 23 integral with the housing 2, retains the drawer 1 in a position in which the key 3 and the deposit piece are simultaneously trapped in the device: effect, the key is both retained by the latch 10 cooperating with the housing 33 of the key 3 and simultaneously by pressing the plane 20a of the drawer 1 on the plane 37 of the key 3, while the drawer 1 containing the deposit piece in its housing 5 is retained by the support of the stud 27 braced in the housing 13 of the end member 9 of the drawer 1.
  • a complete relaxation of the drawer 1 causes the latching of the stud 27 in the housing 13 of the end member 9 of the drawer: the drawer is thus snapped on and the locking piece placed in the housing 5 remains trapped inside the device.
  • the coin contained in the housing 5 of the drawer is trapped inside the device, because the drawer is retained by the latching member 23, in particular because the end 27 of the lever 23 braced inside the latching housing 13 of the end member 9 of the drawer retains the latter inside the housing 2 against the opening spring 4 of the drawer.
  • the key 3 engaging along the inclined plane 18 forming an acute angle with the direction of introduction of the key pushes the drawer 1 in the closing direction and then releases the end 27 of the lever 23 and pushes this end 27 down by pressing the plane 36 on said end 27: the key 3 thus engages between the end member 9 and the latching member 23 by separating them one of the 'other and pushing them away from each other.
  • the key 3 presses by its plane 36 on the end 27 of the lever 23 and thus pushes it down.
  • the drawer 1 unlatched moves back to a position in which the lug 16 of the end member 9 is retained by the support of the plane 21 on the inner face of the wing 31, that is to say the plane 35.
  • the key engages by the inclined plane 32 of the wing 30 in the corresponding orifice of the bolt 10 and thus pushes the bolt 10 against the spring 11.
  • a depression of the key 3 causes the sliding along the outer face of the wing 31 of the end 27 of the latching member 23 to a position in which the end 27 retains the key by cooperation with the plane 37, while passing under the spout 14 and thus avoiding accidental snap-fastening in the housing 13.
  • the key 3 retains the drawer 1 by the cooperation of the planes 21 of the drawer 1 and 35 of the key 3, while the end 27 of the lever 23 retained by the plane 20a of the end member 9 , in turn retains the key 3 by pressing on the plane 37.
  • a depression of the key 3 results in locking by engagement of the lock 10 in the housing 33 of the key under the thrust of the corresponding spring 11.
  • the end 27 of the lever 23 is in equilibrium on the plane 20a of the end member 9 of the drawer 1.
  • the end member 9 escapes through the notch 38 L-shaped formed in the wing 31 of the key 3 and corresponding to the passage of the pins 15 and 16; the retraction of the drawer 1 then enables the surfaces 20 and 19 to be bypassed by the stud 27: therefore the springs 4 and 24 are no longer under stress and can exert their restoring action respectively on the drawer 1 and on the lever 23.
  • the springs 4 and 24 recall the drawer 1 in the open position and the lever 23 in the lowering position of the end 26 and raising the end 27.
  • the recoil of the drawer thus allows access to housing 5 of the deposit and removal of the deposit.
  • the invention also relates to built-in carriages comprising a device described with reference to FIGS. 1 to 19.
  • the device is fixed to the push bar of a built-in cart so that the direction of sliding of the drawer is parallel to the longitudinal axis of the carriage bar or in such a way that the direction of insertion of the key is substantially perpendicular to said longitudinal axis of the carriage bar.
  • a key is connected by a chain or a flexible link similar to a box of a carriage: the device is adapted by adjusting the length of the flexible link so that a key can be inserted into the slot of a neighboring carriage and that it cannot be inserted into the slot of the housing to which it is connected by the flexible link.
  • the key of the first carriage cooperates with the slot in the housing of the second carriage embedded with the first.
  • the housing of the second carriage is in the position shown in FIG. 14, the key engaged in the slot of the housing successively pushes the drawer towards the interior of the housing, the latching member corresponding against the associated spring and the corresponding lock 10 against the associated spring, so as to lock the carriages to one another and cause the drawer to open, which makes it possible to extract the deposit piece from its housing as shown in the figure 19.
  • the second carriage is left with a box corresponding to the position in FIG. 7. It then suffices to place a deposit piece of determined type in the housing 5 of the box.
  • the key and the drawer are engaged with each other by corresponding conformations preventing the release of the drawer and the key.
  • the conformations correspond to the support of the plane 20a on the plane 37 and to the support of the plane 21 on the plane 35: it is understood that the invention also applies to any variant embodiment or modification in the form of these supports having perpendicular directions substantially parallel respectively to the direction of sliding of the drawer and to the direction of introduction of the key.
  • the key is thus directly unlocked by pressing the deposit piece on a notch secured to the lock.
  • the device according to the invention always passes through an intermediate latching position in which the key and the locking piece are simultaneously trapped in the housing.
  • this device provides a means of controlling the outline of the piece placed in the housing 5 and the diameter of the piece pressing the lug 28 passing through the light 29. It is therefore necessary, to operate the device according to the invention, to place a part of the required type in the housing 5. The operation of the device by means of objects having a geometry different from that of the deposit is thus excluded.
  • the present invention has been described with reference to particular embodiments; the invention is in no way limited thereto, but on the contrary includes any modification of form and any variant embodiment within the framework of the invention, relating to a device in which a latching position corresponding to a simultaneous imprisonment of the key and a deposit is obtained.
  • the latching member 23 shaped as a lever can adopt any mechanically equivalent shape in conjunction with the relative movements of the drawer and the key in the housing.
  • the latching member can move in translation, in the case where at least the key or the drawer will be subjected to a pivoting movement or a kinematically equivalent movement.
