Description

The invention relates to a locking device, a trash vat,

  a basket and a collection system. The device of the invention is essentially described here as being intended for a collection basket,

  for example waste, because of its origin.

  This is a simple example of application.

  Indeed, it is also intended for other areas, such as furniture, urban equipment,

  safety and door frames for example.

  These areas, like collecting, are facing

  to the technical problems exposed now.

  A locking device has the function of immobilizing a movable assembly such as a leaf or a movable assembly relative to a frame or support, placed permanently or stationary.

a container tank, for example.

  At least one locking position is provided.

  Usually such a device comprises control means, movable locking means controlled by the control means, and receiving means provided for engaging with the locking means in the immobilization position. It is common, as for the doors, that the receiving means are arranged on the frame, the means

  control and locking being on the mobile assembly.

  In the structures of interest here, the means of

  control, with the locking means, are on the frame.

  The reception means are then on the mobile assembly.

  In addition, congestion, accessibility and location requirements are often imposed. And the displacement of the moving assembly relative to the fixed frame, along a path (of rotation, linear translation or the like), must be possible

  following two directions, for example opposite.

  Entrance and retention must be safe, firm and effective in one direction or the other, indifferently. While the device must be arranged in such a way as not to impede the various movements of

the moving set.

  The connection between the fixed frame and the moving assembly must not only allow the displacement, but often

  the separation or disassembly of this set.

  The assembly and disassembly must be functional operations, fast, without excessive fatigue

  of the operator, nor risk of error.

  These technical problems are specified, by

  reporting to the field of collection bins.

  The document EP-A-219,385 of the Applicant describes a paper bin comprising: - a removable bowl (the moving assembly); a support post (the fixed frame) against which the tank is held by a locking device; - a tank cover connected to the support post; and pivotal articulation means, of horizontal axis, towards the bottom of the tank. A hook of the locking device is connected to the support post and mobile in rotation about a vertical axis. The bowl is provided with a locking tooth with which the hook is engaged in a position

  engagement, under the effect of a return member.

  EP-A-060 794 discloses a comparable structure. DE-U-7,330,880 discloses a basket

  rigidly fixed to the support post.

  EP-A-219,385 provides on the cover

  tank, a rear face in one piece.

  On the one hand, the rear face and the upright limit access to the tank. The trash can not be filled

or emptied only from the front.

  It is therefore difficult to encourage the user to get rid of his waste, while forbidding him to

throw too large objects.

  On the other hand, the pivoting of the tank is possible

  in the only direction before the release.

  If the front is congested (by a vehicle or others), the trash becomes momentarily unavailable,

  for passers-by and for maintenance.

  Similarly, the joining or the separation of the tank on the support post is only possible in a single relative position, which is

not very functional.

  The back of such a basket is unattractive. Its main function is the anchoring of the means

of putting in place of the basket.

  With this basket, the access mouth of the bowl inclined relative to the horizontal allows the visualization of the contents of the tank, which is not

desirable.

  Also, the tank cover offers limited protection of the contents of the basket, for example against bad weather. The mobile hook is directly linked to the means of

  command and biased by the return member.

  In fact, either his command is easy but the recall effect is limited. Either the latter is consistent, but his control requires a tiring and unpleasant effort

when it is repeated.

  The vertical control axis is located at the rear of the bowl cover. This location is not very accessible from the front, where an operator must be placed to control the

  pivoting to the release (emptying) of the tank.

  During maintenance, the handling of the control means should be possible with one hand, in

  leaving the other free to grab the tank.

  In known structures, the receiving means consist of a concave shape with a thin projecting wall, integral with the moving assembly, for example

the back of the tank.

  This unique form, which is solicited in a repetitive manner, can wear out, which can alter the lock. In addition, the trash and collection system should meet the growing requirements

  integration into the environment.

  It is desirable that different types of baskets can be arranged and rigidly attached to one and the same type of debonding means, so that

  optimize the initial investment.

  It is also desirable that the structure of the basket is dissuasive against the wild display and graffiti.

  The invention overcomes these disadvantages.

  It allows easy locking, safe and durable, and the realization of a basket and / or a collection system, possible access by at least

  two of its faces, for users and / or maintenance.

  The same goes for releases / commitments.

  For this purpose, a first object of the invention is a locking device, for example intended for a

collection basket.

  This device makes it possible to immobilize with respect to a so-called fixed support such as a frame placed permanently, a

moving assembly such as a tank.

  Connecting means such as a pivoting joint, being arranged between the fixed support and

the moving set.

  In fact, the latter is movable along a path, between a locking position and at least one release position, in which the movable assembly is able to possibly be detached from the fixed support. Blocking means such as "bolt", controlled by control means and biased towards their locking position by return means, are integral

of the frame.

  While receiving means or "waste" are arranged on the mobile assembly, to cooperate with the

  locking means in the locking position.

  According to one characteristic, the connecting means are arranged to allow movement (disengagement and engagement) of the moving assembly in two opposite directions of the trajectory, on either side

a locking position.

  The receiving means comprise at least one ramp -and for example two ramps-facing blocking means in the locking position, rigidly secured to the moving assembly, for example an edge or mouth

access to the tank.

  The generally extended ramp along the trajectory is provided with a form of immobilization of locking means, and on either side of this shape along the trajectory, of an introduction bevel whose acute end is respectively opposed to the form of immobilization. For example, the ramp has an asymmetrical structure with respect to a plane perpendicular to the path and parallel to a corresponding direction of biasing the biasing means, on either side of the immobilization shape along the path. The form of immobilization also has an asymmetrical shape in the same plane, with on the one hand a high bearing front, forming a main stop, and on the other hand a low clearance front, of reduced size with respect to the front.

  up, following the direction of solicitation.

  According to one embodiment where the immobilization form is asymmetrical, the high front is substantially contiguous to a ramp bevel, while the low front is connected to the other ramp bevel via a bevel of introduction. preferential, substantially parallel to or orientation

close to that of the contiguous bevel.

  In an example providing at least two ramps, a ramp with a high front substantially perpendicular to the trajectory in the locking position, and oriented in one direction, while the high front of the other ramp, substantially perpendicular to the trajectory in position of locked, is oriented in the opposite direction according to the

path.

  In one embodiment, the ramp is at least partly made of material with the moving assembly and / or an insert of wear-resistant material such as a metal such as steel or the like, is part of the ramp, the insert 1 embodiment provides that the locking means comprise at least one finger whose free end is engaged with a form of immobilization of the receiving means in the locking position, this finger presenting the following a plane substantially parallel to the trajectory and / or the biasing direction of return, a substantially symmetrical end profile, for example trapezoidal.According to another characteristic, the locking means comprise at least two autonomous mechanisms, at a distance from each other. others as well as control means

  common, and each provided with own recall means.

  The receiving means then comprise a ramp, facing each locking mechanism in the locking position, and rigidly secured to the moving assembly, for example an access edge to the tank, the control means being provided, for each mechanism, a flexible transmission element and able to transmit to the corresponding mechanism tensile stresses exclusively, in a direction opposite to that of the biasing of its return means, from the means of

  command common to these mechanisms.

  The control means are pivotable, and comprise a lever, connected to each transmission element which is able to exert traction, respectively, via means of return of angle possibly, on the locking means which are

  movable in rectilinear translation.

  One embodiment provides two locking mechanisms and return means, respectively disposed on either side of the movable assembly relative to the trajectory. In this case, the control means are locally extended substantially parallel to the trajectory and / or

  a direction of solicitation of the return means.

  For example, the control means are locally extended in a direction of elevation substantially centrally between the two means of return and / or in a transverse direction, remote from the receiving means in the direction of stress,

in the locking position.

  One feature provides that the connecting and locking means are arranged substantially symmetrically with respect to a central plane, substantially parallel to the trajectory and to a bias direction and / or control means so as to

be reversible to commitment.

  One feature provides that the connecting and locking means are disposed substantially symmetrically with respect to a central axis, substantially perpendicular to the path and / or parallel to a biasing direction, so as to be reversible on engagement. Another object of the invention is a trash vat, for example waste collection, intended to be equipped with at least one locking device as evoked. This tank is provided, in one embodiment, with an access mouth extended substantially perpendicularly to a direction of elevation, according to which the vessel is generally arranged in the locking position, and / or at least one organ of the tanks. connection, such as a hinge feed, and for example two, near an end opposite the mouth in the direction of elevation, arranged substantially to the right of receiving means in the direction of

elevation.

  At one end of the tank opposite an access mouth, in a direction of elevation in which the tank is generally arranged in the locked position, is provided a wear pad, for example central and transverse, intended to cooperate with a fixed frame track. The pad is arranged substantially to the right of control means in the direction of elevation, and / or

  centrally between members of the connecting means.

  One embodiment provides that the tank is substantially symmetrical with respect to an axis parallel to

  a direction of elevation and / or stress.

  Yet another object of the invention is a collection basket, for example waste, equipped with at least one locking device and / or a tank as evoked. One feature provides that the fixed frame defines a substantially closed loop space, the connecting means and / or receiving and / or blocking being

  arranged inside this space.

  According to one embodiment, the fixed frame and / or the vessel comprises -or is essentially constituted by a shell of synthetic material, such as rotomolded plastic

or injected to the press.

  One feature provides that the fixed frame has a connection lumen to the control means, substantially at its top and / or has a vaulted cowl entirely extended projecting to the right of a

mouth of tank.

  A further object of the invention is a collection system, comprising at least one locking device and / or a tank and / or a basket of

collection, as mentioned.

  According to one characteristic, the system comprises means of abutment such as central foot and / or transverse base joining two lateral uprights of the fixed frame. The invention is now described in detail with reference to the accompanying drawings, which show modes

  non-limiting embodiment of the invention.

  In the drawings, FIG. 1 is a perspective view of three quarters front, of a collection system with a street basket, according to the invention, and

provided with a central foot.

  FIG. 2 is a view similar to FIG. 1, which shows a system provided with an enveloping base

  in "U" with side elevation branches.

  Figure 3 is a cross-sectional and central sectional view of a collection system, as well as a

  locking device according to the invention.

  Figure 4 is a cross-sectional view of a system and a collection basket according to the invention, with the vessel in one of its two states of disengagement. FIG. 5 is a view similar to FIG.

  central locking position of the tank.

  FIG. 6 is a front elevational view and partial view of the system and the collection basket of the

Figure 4 or 5.

  FIG. 7 is a partial view in section of side elevation of a locking device and

  of a basket according to the invention.

  FIG. 8 is a side elevational view of a ramp insert intended to form part of receiving means for a locking device according to the invention. FIG. 9 is a view similar to FIG. 7, illustrating in detail receiving means and locking means, the latter being represented in fine lines in their locking position, and in strong lines in FIG.

their release position.

  FIG. 10 is a partial view, in plan section, showing the single control means lever and two flexible connecting elements, as well as a mechanism of the locking means, with its means of

fixing on the frame.

  In the figures, three directions L, T, and E are represented. The direction L is referred to as the lateral direction. The direction T is said transverse direction. Direction E

is called elevation direction.

  To simplify the description, the directions

  Orthogonal lateral L and transverse T are considered here as being substantially horizontal. They jointly define a horizontal support plane L, T. The elevation direction E is considered here to be substantially vertical, and therefore perpendicular to

horizontal directions and plane.

  The constituents of the invention including the locking device, the tank, the basket and the collection system, described here with respect to the directions L, T and E,

  can take different positions in space.

  This is particularly the case of the mobile elements constituting the invention, but also of so-called "fixed" or "permanent" parts, especially when

manufacturing or storage.

  Therefore, these directions in no way limit the invention, and are simply intended to simplify its understanding. In the figures, the reference 1 denotes a collection basket, and the reference 2 a collection system comprising a (in some cases not shown)

several) collection basket 1.

  The collection system 2 comprises means of

put in abeyance 3.

  In FIG. 1, the biasing means 3 essentially comprise a central foot whose one end is said to be upper in the direction of elevation.

  E, makes it possible to rigidly fix a support of the basket 1.

  The opposite lower end of the central leg 1 is rigidly fixed on the horizontal support plane L, T. This generally comprises a floor or road surface such as a sidewalk, a building slab, a floor

or the like.

  The means 3 thus make it possible to place the system 2 permanently, and consequently the basket 1, with respect to the support plane L, T. In FIGS. 2 and 4 to 6, the abutment means 3 comprise a base Lateral also rigidly fixed to the support plane L, T. This base is generally shaped "U" in a plane defined by the directions L and E, and envelope

  thus laterally the basket 1, in part.

  The latter comprises in particular a support said fixed frame 4, rigidly secured to the means of setting

remains 3.

  The basket 1 also comprises a set 5,

mobile with respect to the fixed frame 4.

  FIGS. 4 to 6 show connection means 6 arranged between the fixed frame 4 and the assembly

mobile 5.

  This is a pair of pivoting joints, but other types of connecting or guiding means such as slide or the like can also

to be provided.

  The connection means 6 serve to make the moving assembly 5 displaceable with respect to the fixed frame 4. The relative displacement of the moving assembly 5 with respect to the fixed frame 4 is carried out along a path D shown in the figures 4 and 5, in particular. The connecting means 6 are here pivoting, of substantially extended axis in the lateral direction L. The trajectory D here has a shape of a circular arc to

large radius.

  For example, the means 6 comprise two male members on the moving assembly 5, and two complementary female members on the fixed frame 4. The opposite case is

  shown in Figures 4 to 6.

  Note that at the right of the connecting means 6, the tangent to the path D is substantially parallel to the

  transverse direction T. To simplify the description,

  it can be considered that the path D is locally a straight line parallel to the transverse direction T. The displacement along the path D is provided here between a single and central locking position (FIGS. 1 to 3, 5 to 7, 9 and 10) , and release positions. FIG. 4 shows the moving assembly 5 in a position of extreme disengagement or disassembly of the assembly 5. The latter can also be placed, along the path D, in a position of opposite extreme clearance. This opposite extreme position places the moving assembly 5 symmetrically with respect to a plane parallel to the direction E and passing through the connecting means 6 (that is to say on the right in FIG. 4).

  To simplify the description, we designate the

  Extreme release positions simply by "disassembly position". It is nevertheless clear that a plurality of intermediate clearance positions are possible between

the two extreme positions.

  The connecting means 6 in particular are arranged so that in one and / or the other disassembly positions, the movable assembly 5 can be detached or dismounted from the fixed support 4. The means 6 then comprise

removable joints.

  In the figures, the general reference 7 designates a

locking device.

  It is recalled that such a locking device 7, described here as being intended for a basket 1 or a collection system 2 is not limited to this application, but may be intended for other structures such as furniture, doors, technical boxes, storage units

for industry or the like.

  This device makes it possible to immobilize with respect to the frame 4, which is placed permanently, the assembly 5 which is movable along the path D. The device 7 thus makes it possible to obtain between the disassembly positions, a so-called locking position, wherein the moving assembly 4 is momentarily locked, immobilized and locked. Its function is therefore similar to

that of a lock.

  The locking device 7 comprises control means 8, locking means 9, return means 10 and receiving means 11, mainly. The control means 8 make it possible to actuate the locking device 7. In the figures, the means 8 comprise in particular a bushing 12 intended to receive an operating key (not shown) which can itself be actuated by an operator wishing to switch on. the device 7. The socket 12 is here a female housing

tool or key.

  The control means 8 are integral with the fixed frame 4, and comprise several pieces guided so

  to be movable or mobile, relative to the frame 4.

  The control means 8 make it possible to act on the

  locking means 9, also secured to the fixed frame 4.

  Some constituents of means 9 are fixed and

  others are movable, compared to the frame 4.

  The displaceable locking means 9 are arranged to cooperate with the moving assembly 5, in particular in the locking position of the latter. The means 9, comparable to a "bolt", are also permanently urged towards their locking position by the

  return means 10, which are integral with the frame 4.

  In the figures, the displaceable parts of the control means 8 are mounted idle, and are biased under the effect of the return means 10, via the blocking means

9 in particular.

  Return means 10 specific to the control means 8 may act on these directly, together with other return means 10, specific to the

locking means 9.

  Therefore, it is possible to oppose the action of the return means 10 by acting on the control means 8. This interrupts the cooperation between the means of

blocking 9 and the moving assembly 5.

  When the control means 8 are released, the return means 10 return in particular the locking means 9 in their locking position o they

  cooperate with the assembly 5 to immobilize it.

  In the locking position, the locking means 9 cooperate with the receiving means 11 which are

  secured to the movable assembly 5 and arranged thereon.

  These means 11 therefore serve as "waste".

  With the connecting means 6 which allow the disengagement and engagement displacements of the moving assembly 5 in two opposite directions of the path D, on either side of the locking position 11, the

  receiving means (11) comprise at least one ramp 13.

  In the figures, two ramps 13 of the receiving means 11 are respectively placed opposite blocking means (when in the locking position). Each ramp 13 is generally extended along the path D. It is provided with a form of immobilization 14, which allows the housing of a displaceable component of the locking means 9, in position

locking.

  On both sides of the immobilization form 14 along the path D, the ramp 13 comprises two introduction bevels 15 and 16. Each introduction bevel 15 and 16 has an acute end along the path D, respectively opposite. to the form of immobilization 14. The latter is disposed between the two bevels of each ramp 13, along the path D. This

  spring in particular from Figures 8 and 9.

  It can be seen that the ramp 13 has an asymmetrical structure with respect to a plane perpendicular to the trajectory D and parallel to the elevation direction E, here confused with a direction of stressing

  return means 10, on either side of the form 14.

  The form of immobilization 14 delimits a housing also asymmetrical, with respect to a plane perpendicular to the path D, the center of the form 14. On the one hand, the shape 14 has a high bearing front, which serves main stop for a part

locking means 9.

  On the other hand, the form of immobilization 14 presents

a low clearance front 18.

  FIGS. 7 to 9 show that the dimension of the high front 17 in the direction of elevation E is greater than the dimension of the low front 18 along this same direction E. Due to its reduced size compared to the high front 17, the low front 18 has a more favorable arrangement for the release of the locking means 9 out of

receiving means 11.

  While the upper face 17, due to its larger size, forms a main abutment favoring the support in the direction D of the locking means

9 in the form 14.

  The high front 17 is here contiguous to the bevel 15 of the ramp 13. The bevel 15 is therefore said support bevel to

like the contiguous front 17.

  The low front 18 is in turn away from the bevel 16, and said clearance. It is separated by a counter-bevel 19 said preferential introduction. The preferential introduction bevel 19 is substantially parallel to or at least close to that of the bearing bevel 15 contiguous to the high front 17.

  In FIG. 8, relative to the transverse direction T, at its tangent parallel to the trajectory D, the following surface orientations are observed: the slope of the support bevel 15 is oriented from the outside of the ramp 13 towards the interior o is arranged in the form of immobilization 14, from bottom to top following a

  angle of the order of 15 to 20, for example 170.

  similarly, the orientation of the clearance bevel 16 from the form 14 to the clearance bevel 15 is from bottom to top at an angle of

the orde from 14 to 17.

  - The clearance bevel 16 is oriented, from the acute end of the ramp 13 to the bevel against 19, from bottom to top at an angle between 17 and 22,

for example of the order of 190.

  In FIGS. 7 to 9, the ramp 13 has its high front 17 substantially perpendicular to the trajectory D. This front 17 is oriented in a counter-clockwise direction.

  bevel 19 and the clearance bevel 16.

  The lower clearance face 18 is inclined relative to the transverse directions T and elevation E. From the bottom of the shape 14 towards the clearance bevel 16, the inclined front 18 is oriented from bottom to top at an angle between 50 and 60, and

example of the order of 55.

  This allows the constituent blocking means 9 which cooperate with the form 14 in the locking position, to be pressed by the inclined front 18, against the front 17 main stop. Locking is thus further improved. In FIG. 9, it can be seen that the locking device 7 has two ramps 13. A ramp 13 (represented in solid lines) has its high front 17 oriented in a direction along the path D. While the upper face 17 of the another ramp 13 (shown in dotted lines) is oriented in the opposite direction

  following the direction T or the path D locally.

  The two ramps 13 of this device 7 are thus arranged "head-to-tail". This also improves the

  locking, spreading efforts.

  FIG. 9 shows that the ramp 13 is at least

  part of the material with the moving assembly 5.

  It can be entirely matter.

  Here, an insert 20 shown in FIG. 8, is intended to form part of the ramp 13. An insert 20 is in this embodiment embedded in the moving assembly 5, for each ramp 13. The insert 20 is chosen from a resistant material

  wear, such as a metal, for example steel or the like.

  It is shaped to present an anchoring pan 21 to the moving assembly 5, as well as several surfaces

  substantially perpendicular to the anchoring pan 21.

  They respectively define (from right to left in FIG. 8) the support bevel 15, the high support face 17, the immobilization form 14, the low clearance face 18, the bevel and the

clearance bevel 16.

  Fixing means 22 are here provided in the form of fastening orifices, for the passage of studs of material and / or anchor pins reported, for example such

screw, rivets or the like.

  When an insert 20 is provided, its anchor 21 is for example arranged parallel to the directions E and T against an outer edge of the moving assembly 5, facing the fixed frame 4. As for the shapes, fronts, and bevels (14 to 19), this allows the insert 20 to resist shocks and

  act as a wear part laterally.

  In Figures 3, 7, 9 and 10 the reference 23 shows a movable finger forming part of the locking means 9. A free end of the finger 23 is engaged with the immobilization form 14 in the locking position. This free end is the constituent

  locking means 9 which cooperates with the ramp 13.

  The finger 23 has at its free end, in a plane substantially parallel to the path D and the elevation direction E, a substantially symmetrical profile.

Trapezoidal shape.

* In Figure 9, the free end of the finger 23 has two faces inclined from bottom to top and towards the center of the finger, and a central end face, substantially parallel to the directions T and L. The inclined faces have a comparable orientation, or slightly more inclined relative to the direction T, than the front

clearance clearance 18.

  For example, each inclined face of the free end of the finger 23 has an angle of the order of 60 relative to the direction T. In the same figures, the reference 24 designates a

  fixed platen for supporting and guiding the finger 23.

  The support and guide plate 24 comprises

  anchoring lugs 25 or rigid attachment to the fixed frame 4.

  Some achievements make it possible to realize the stage 24

  material coming with the fixed frame 4.

  Here, the plate 24 is attached and dismountably mounted on the fixed frame 4. The fixing is here ensured by mounting means 26, represented here by

  two sets screw-nuts-washers.

  The anchoring tabs 25 are arranged against a plane of the fixed frame 4 substantially parallel to the directions T and E. And the mounting means 26 are substantially extended in the direction L. The plate 24 internally defines a guide sleeve 27, of shape elongated and extended mainly along the E direction of elevation. According to the embodiments, the guide sleeve 27 is either entirely made of material. Either she is

  closed by an attached cover 28, as in Figure 10.

  Either it is still closed by a contiguous wall of

fixed frame 4.

  The function of the sleeve 27 is to guide the finger 23 in translation or rectilinear sliding according to the

  elevation direction E, substantially.

  FIG. 10 shows that in section along a plane parallel to the transverse directions T and longitudinal L, the inside of the guide jacket 27 has an outline

  substantially polygonal, here substantially square.

  The finger 23 of the blocking means 9, which is itself

  also extended mainly in the direction of elevation E, has an outer contour complementary to the inner contour of the sleeve 27, in the same section. More specifically, an external guiding portion of the

  finger 23 is section or square with beveled corners.

  The respective dimensions of the finger 23 and the guide sleeve 27 are determined to provide a certain clearance allowing a sliding of the finger 23 in the direction of elevation E. In the direction E, the inside of the guide sleeve 27 is here two opposite ends open. A so-called lower end of the sleeve 27 opens opposite the ramp 13, in the locking position. It allows the passage of the free end

finger 23.

  The opposite end of the finger 23 is said to be upper

  inside the shirt 27 regardless of its position.

  And it is arranged opposite the opposite end opening of the sleeve 27, in the direction of elevation E. In the sleeve 27, opposite in the direction E of the open end traversed by the finger 23, is

provided a hold 29.

  The wedge 29 protrudes into the cavity delimited by the inside of the jacket 27. In FIG. 10, the wedge 29 protrudes along the lateral directions L and transverse T. Note that in the plane defined by these two directions, the section of the shim 29 is significantly smaller than that of the cavity defined by the sleeve 27. The shim 29 thus leaves at least one passageway 30, which gives access to

inside the shirt 27.

  One end of return means 10 is secured to the base 29. Here, the base 29 is rigidly secured, but removably, of such an end. Reminder means 10 have their opposite end in the direction E integral with the finger 23. A face facing the wedge 29, for example perpendicular to the

  direction E, here serves as support for this end.

  Such a face could be an external upper face

finger tip 23.

  In FIGS. 7 and 9, it can be seen that it is an internal bearing face extended in the lateral directions L and transverse direction T substantially, forming the blind end of a channel 32, itself generally extended. along the direction E. The return means 10 mentioned above are fully housed in the channel 32, formed inside the finger 23, between a bearing surface 31 of the finger 23, and the wedge

29 of the support plate 24.

  Inside these means 10, and therefore the channel 32, is also extended a section of a cable 33 described

further.

  Like a damping plug 34, is interposed between the face 31 and the end opposite the wedge 29 means 10 evoked. The plug 34 is to be considered as

as part of these means 10.

  This arrangement of the return means 10 between the fixed shim 29 and the support surface displaceable with the finger 23, allows the latter to be permanently biased in the direction of elevation E, to its locking position o its end free is housed in the form

14.

  In the sleeve 27, the elevation direction E and

  the direction of solicitation are confused.

  In the figures, the locking means 9 comprise at least two autonomous mechanisms, at a distance from each other, as well as common control means 8. Each

  means 9 is provided with own return means 10.

  Each mechanism includes a finger 23, a platinum

24, mainly.

  It can be seen from the figures that the own return means 10 of these mechanisms of the locking means 9 comprise, in addition to the damping plugs 34, each a helical spring of stainless steel, mainly extended in the direction of elevation E and installed in

  the corresponding channel 32 of a finger 23.

  The receiving means 11 then comprise a ramp 13, opposite each locking mechanism (23,24)

in the locking position.

  The control means 8 are provided, for each mechanism, with a flexible transmission element, here a

cable 33.

  Each cable 33 is at one of its free ends,

rigidly secured to a finger 23.

  Its other free end is secured to a lever

Control means.

  In the figures, the cable 33 is a cable of the type

  "push-pull" formed of braided and sheathed steel strands.

  As is apparent from FIG. 3, angle return means 36, rigidly secured to the fixed frame 4, are arranged between the two free ends of each

cable 33.

  In these embodiments, the angle return means 36 comprise, at the right of each support plate 24 in the direction of elevation E, a sliding guide of the cable 33, which defines a bent groove opening on the one hand to a lever 35, substantially parallel to the support plane L, T. The gutter opens on the other hand, and more precisely on the opposite, in

look at the channel 32 of the finger 23.

  Note that with respect to the lever 35, each gutter of the angle deflection means 36 is flared to allow a certain displacement of the orientation of the cable 33 in the support plane L, T, between the support plate

24 and the lever 35.

  The cable 33 is a flexible transmission element capable of transmitting to the corresponding locking mechanism,

  tensile stresses exclusively.

  These traction constraints are directed in a direction S opposite that of the solicitation of the corresponding own return means 10, from the means of

common command 8.

  Figure 3 shows common control means 8

Swivel.

  In fact, the sleeve 12 is rotatably mounted in a complementary housing of the support frame 4. The sleeve 12 is thus able to be rotated about an axis parallel to the elevation direction. A stop screw 37 holds the sleeve 12 in the direction of elevation

E, with respect to the fixed frame 4.

  FIGS. 7 and 10 show that each cable 33 is provided at each of its free ends with a head

salient 38.

  The finger 23 has between its inner bearing face 31 and its free end, a through groove in which the cable 33 is passed. The head 38 of this end, is also disposed in this groove, so as to make the finger 23 and the cable 33, in the direction E and in a direction S (FIG.

  to the solicitation of the means of recall 10 own.

  Similarly, a groove is provided at each free end of the lever 35, for the engagement of a cable 33 and the securing of a corresponding head 38 of this cable. FIG. 10 shows, for one of the cables 33, a local direction S of traction of this cable,

  between the angle return means 36 and the lever 35.

  It emerges from this figure that a rotation in the trigonometric direction (in top view) of the lever 35 which is rigidly fixed at its center to the bushing 12 causes the traction of the cable 33 (at the top of the figure), following the

direction of the direction S shown.

  20. The other cable 33 (bottom in FIG. 10) is biased in the same direction of traction, but in the opposite direction, when the lever 35 is rotated

  by the sleeve 12, in the trigonometrical direction.

  The maximum angle of rotation of the lever 35, designated at A, is here of the order of 45, from rest position to

unlock position.

  As a result of the distance between the axis of the bushing 12 and the heads 38 of the cables at the free ends of the lever 35, a reduction of effort per arm of

the sink.

  In the locking position, as in the figure, the lever 35 is substantially extended in the transverse direction T, that is to say parallel to the trajectory D. The pivot axis of the sleeve 12 being aligned with the center of each sleeve 27 and each channel 32 of the locking means 9, in the direction L, the cable 33 is thus extended locally inclined with respect to the longitudinal directions L and transverse T, between the

  angle return means 36 and the lever 35.

  Note that the angle of inclination of the cables 33 with respect to the direction L varies so as to decrease when the lever 35 is rotated in the counterclockwise direction in FIG. 10, around the fixed point

  constituted by each passageway 30.

  It is for this reason that the gutter of the angle return means 36 is flared in the form of "V", in the plane parallel to the longitudinal directions L and transverse T. The tip of this "V" is opposite to the socket 12, in the direction L. In FIG. 10, in the locked position, the inclination of each cable 33 with respect to the longitudinal direction L is between 20 and 25, and is

example of the order of 22.

  The control means 8 which are pivotable, therefore comprise a lever 35, connected to each transmission element 33, able to exert traction via the angle deflection means 36, on the locking means 9 which are

  they are movable in rectilinear translation.

  The two locking mechanisms and the two return means 10, are respectively disposed on either side of the moving assembly 5, with respect to the path D. The common control means 8 are, with regard to the lever 35, extended substantially parallel to the path D, and as regards the sleeve 12, substantially parallel to the direction of solicitation

  own return means 10, in the rest position.

  The control means 8 are elsewhere generally extended in the direction of elevation E, substantially centrally between the two return means 10. They are also extended in the transverse direction T, away from the receiving means 11 in the direction biasing, in the locking position. With such an arrangement, it is provided as is apparent from FIGS. 4 to 6, that the means of the links 6 and the moving assembly 5 are substantially symmetrical with respect to a central axis parallel to the elevation direction E, and coincident with the axis of rotation of the

socket 12.

  This allows the moving assembly 5 to be reversible on engagement. This assembly 5 is thus able to be locked to the fixed frame 4, from two positions, indifferently. Let us describe more precisely the tank which essentially constitutes the moving assembly 5 in the figures. This tank, intended to be equipped with at least one locking device 7 as evoked, is also designated by the

  general reference 5, to simplify the description.

  According to the embodiments, the tank 5 is a

  rotomolded piece or injected plastic material.

  In the locking position (FIG. 5), it partly projects in the transverse direction T, of each

fixed frame face 4.

  The tank 5 is provided with an edge or access mouth 39 extended substantially perpendicular to the elevation direction E, according to which the tank 5 is generally

  arranged in the locking position.

  The tank 5, in the shape of an inverted bell, has elevation walls extended along the direction E, as well as a bottom, curved in shape, concavity facing the means of abutment 3 (FIGS. 4 to 6) to opposite

from the access mouth 39.

  The tank 5 is provided with external grooves 40, substantially U-shaped in a plane parallel to the lateral directions L and elevation E, which limit the areas offered for the wild display, while

  participating in the rigidity of this tank.

  The members of the connecting means 6, here two hinge feeds, are provided on the tank 5 near an end opposite the mouth 39, in the elevation direction E. The members of the connecting means 6 are arranged substantially in line with the receiving means 11, in the direction of elevation E. In the plane defined by the directions L and E, the members of the connecting means 6 are thus arranged on either side of the tank 5, in the lateral direction L. A wear shoe, for example central and transverse, is provided at one end of the tank 5 opposite the access mouth 39, in the direction of elevation E. This wear pad, is intended to cooperate with a complementary track of the fixed frame 4. The wear pad is for example in the form of protruding strip of the outer bottom of

the tank 5.

  It is arranged substantially to the right of means of

  command 8, in the direction of elevation E, that is,

  say centrally between the members of the connecting means 6. The tank 5 is here substantially symmetrical with respect to a central axis parallel to the elevation direction E. This allows a reversible mounting of the tank 5 on the fixed frame 4, in two mating arrangements of

liaison means 6.

  The collection basket 1, for example for the collection of waste such as fatty papers or the like, is equipped with at least one locking device 7 and with

less a tank 5 as evoked.

  The fixed frame 4 defines a substantially closed loop space, inside which are arranged the connecting means 6, and the receiving means 11, the means of

  blocking 9 and most of the control means 8.

  Like the tank 5, the fixed frame 4 is essentially constituted by a shell of synthetic material, for example rotomolded or injected to the press. The fixed frame 4 comprises a light 41 for connection to the control means 8, substantially at its top. The substantially central light 41 is provided on a cover 42 of the fixed frame 4. The cover 42 is, as is apparent from FIGS. 1 to 6, in the form of an extended arch

  protruding right of the mouth 39 of the tank 5.

  Such a basket 1 integrates with the means of

  notice 3, to the collection system 2.

  In the locked position (FIG. 5), the tank 5 is blocked on the frame 4 and users such as bystanders can deposit their waste in the tank 5, via the access mouth 39 and the arc-shaped opening. of

  concavity circle turned towards the base 3, the cover 42.

  For the maintenance of the system 2 or the basket 1, it is often necessary to clear the basket 5, as in Figure 4. To do this, an operator has a suitable key, for example four-sided, in the sleeve 12. It exerts on the key a rotational force, here

  in the trigonometric direction in top view of the system 2.

  This effort on the key, is transmitted to the sleeve 12 and lever 35 which move from their position in strong line in Figure 10, to the position in broken lines. Here, the displacement from one position to the other corresponds to the angle A of the order of 30 to 60, and by

example of the order of 45.

  The rotation of the two opposite arms, initially extended in the transverse direction T, of the lever 35,

  pulls S on the cables 33.

  The latter, at their ends opposite the lever 35, urge the fingers 23 in the direction S of FIG. 7. This simultaneous movement of the two fingers 23 is effected against the force exerted by the means

  own biasing levers 10 of opposite orientation.

  As in FIG. 9, under the effect of the traction of the control means 8, the free end of each finger 23 is lifted in the direction S (or the direction E) from its dotted position in FIG. position in solid line. In this latter position the free trapezoidal end of the finger 23 is at a distance of

the corresponding ramp 13.

  The tank 5 which is mounted idle or slightly rotatably braked on the connecting means 6, can then be pivoted about an axis parallel to the direction L, in the direction illustrated in FIG. 4 - or in the opposite direction - the trajectory D. In such a release position, the interior of the tank 5 can be

previewed.

  Continuing the movement of the tank 5 along the path D, to the disassembly position, the tank can be detached from the frame 4, for example to be emptied. To do this, it suffices to raise it so as to separate the male and female members from the connecting means 6. The assembly of the tank 5 on the frame 4 consists of a reverse movement, in the disassembly position, and more precisely in the one of two dismantling positions

  possible since the tank 5 is reversible.

  It is clear that the control means 8 have been actuated simply to release the finger 23 out of the

form 14.

  Then they are released and return to a position where these fingers 23 are in the location shown in solid lines in Figure 9, under the effect of the means

own recall 10.

  The key operated by the operator is therefore very

quickly released.

  The fingers 23 return after release, in a position in which they can be put back into engagement

  with the form 14, in the locking position.

  Once the tank 5 is put back on the fixed frame 4, it is sufficient to rotate the latter in the opposite direction to first bring the fingers 23 into contact with one of the bevels 15 or 16, respectively, of this tank. By continuing the movement, the return means 10 are compressed which causes a displacement following the

direction S of the fingers 23.

  By continuing the displacement of the tank 5 along the path D towards the locking position,

  the free end of the finger 23 reaches on one side the counter

  bevel 19 and on the other side the end of the bevel 15

contiguous to the front 17.

  When the locking position is reached, the free end of the finger 23 enters and stops in the shape 14 and blocks the tank 5. The invention makes it possible, as we have seen, to solve problems such as: access to the mouth of the tank, without the locking device is an inconvenience; - Limit the size of this device; provide a convenient and accessible location for the control means, and guaranteeing extremely secure locking by the locking means simultaneously; - allow the release / engagement of the tank along several directions of the same trajectory; - Allow a quick and reversible dismantling and joining of the tank; - achieve reliable, safe, fast, practical operation, not involving excessive fatigue or risk of error; - Allow an operator to operate the control means with one hand, the other hand remaining available to manipulate the vessel; and - to distribute the technical organs at a distance from each other, to allow more freedom to obtain an aesthetic structure, offering effective protection, easy to integrate into the environment and allowing different types of baskets to be placed rigidly on one and the same type of

  remains, in order to optimize the initial investment.
