Definitions
- the invention relates to a device for printing on an object, preferably a thin object, a free rapid pivoting movement on itself, for example around one of its axes.
- This object can for example be a ring, a torus, a disc, a spinning top, a sphere, and more generally an object having a shape of revolution.
- the invention applies in particular to toys.
- the stops When the object is pushed in, the stops remain constantly in abutment against it, until a maximum spacing from which, in a second step, under the spring return action, they come together by expelling powerfully the object, in the same direction as that of its insertion, to direct it towards cam means which strike the object transversely so as to impart to it a pivoting movement around an axis which generally coincides with the axis movement of the object in the device.
- the object of the present invention is to provide a device of the same type, that is to say with stops and cams, by improving it in particular as regards the means which ensure the expulsion of the object and the means which impart its pivoting movement on itself.
- the invention aims to improve the device known above with regard to the means making it possible to bring the object into the support position on the stops, that is to say into the standby position. deportation.
- the invention aims to improve the device known above by providing means which facilitate the launching of the object relative to the receiving surface on which it is intended to evolve by pivoting around one of its axes.
- the invention aims to improve the device known above by giving the object a kinetic energy of pivoting without taking it from the kinetic energy due to the longitudinal movement of expulsion.
- the device for imparting to an object a free rapid pivoting movement on itself, in particular around one of its axes comprising a body having a passage for the passage of said object, first means for forcing the movement of said object along the corridor, from the entrance to the exit thereof, the second means for expelling the object towards the exit from the corridor, said second means being permanently resiliently recalled towards the axis of the corridor and being mobile, under the action of the forced displacement of the object, between an active deployed position for which they extend partly across said corridor, on the path of the object, and an inactive retracted position for which they release the passage, while remaining in contact with the periphery of the object, of the third cam means, provided opposite the exit from the corridor and arranged to act on the expelled object under the effect of the elastic return of the two xth means, the action of the cam means taking place according to at least a pair of two equal forces and opposite directions applied in the vicinity of the periphery of the object and perpendicular to the direction of advance of the object
- the device comprises two similar levers (or two springs) which are arranged symmetrically with respect to the axis of the direction of advance of the object inside the corridor of said device.
- the lever successively comprises, on its face facing the path of the object, a stop ramp capable of stopping the object before its expulsion and a cam arranged to act transversely on the object and to print the pivoting movement.
- the ramp ends with an active edge of forced expulsion of the object towards the cam; preferably, the distance between this active edge and the cam is such that the object being expelled cooperates both with said edge and with said cam, before said lever returns to the active deployed position, so that the cam prints to the object a pivoting movement while it is still moving towards the active deployed position and the object being expelled is still pushed by said active edge;
- the cam is constituted by a facet, in particular planar, extending parallel to the direction of expulsion and in an inclined plane relative to the tilting plane of the lever or to the elastic return plane of the spring.
- the lever has, between the ramp and the cam, a recess for receiving a pin which is fixed relative to the body and which constitutes a stop for limiting the active deployed position of the lever.
- a spring is provided between the body and the lever to return the latter permanently to its active deployed position.
- the body comprises a handle having two parallel channels: a first channel forming a store for receiving objects bearing on each other at their periphery, and a second channel for receiving a piston d expulsion which comprises an outer operating end, projecting from the handle, and an active inner end adapted to cooperate with the object to be expelled, a spring being provided to return the expulsion piston to its rest position, said two channels communicating at their lower ends by a bent part of the first channel opening into the second channel substantially at the active end of the expulsion piston.
- the length of the second channel, beyond its connection with the bent part of the first channel, is such that only one object at a time can access the second channel, under the expulsion piston, the next object, when the first object is in the expulsion standby position, pressing on it while remaining in the angled connection part and being held there by the expulsion piston when the latter is actuated to expel the first object, and the second object coming by gravity to take the preceding place of the first object only after the expulsion piston has returned substantially to its rest position under the action of the return spring.
- the expulsion piston has a longitudinal cavity which, on the one hand, receives said piston return spring, this spring being in abutment against one end of the cavity and, on the other hand, is crossed, in the vicinity of its other end, by a fixed transverse pin forming a stop for the spring.
- the expulsion piston has abutment means capable of limiting its driving stroke so that, for this extreme driving position, the active end of the piston cannot interfere with said ramp and, therefore, cannot not hinder the return of the lever (or spring) to its active deployed position.
- These means of abutment of the expulsion piston are for example constituted by the curved and enlarged profiled outer end of the piston abutting against the upper edge of the body.
- the lower end of the body comprises means for coupling to a support to facilitate or regulate the expulsion of the object, said support constituting a support for the body and defining the height at which the object is expelled relative to its surface of evolution which receives it for the accomplishment of its pivoting movement on itself.
- the device according to the invention comprises a body (1) in which objects (2), which are preferably of small thickness, for example in the form of a ring, torus or disc, but which can also have for example a spherical shape or more generally of revolution, can be introduced by gravity and from which they are expelled one by one, being animated by a free movement of swiveling quickly on them- same, about an axis which is generally parallel to the direction of expulsion, that is to say parallel to the direction of exit of the device.
- objects (2) which are preferably of small thickness, for example in the form of a ring, torus or disc, but which can also have for example a spherical shape or more generally of revolution, can be introduced by gravity and from which they are expelled one by one, being animated by a free movement of swiveling quickly on them- same, about an axis which is generally parallel to the direction of expulsion, that is to say parallel to the direction of exit of the device.
- the body (1) which for example consists of several pieces of plastic material molded and / or machined, comprises an upper part which constitutes a handle (3) and inside which are formed two parallel channels.
- a first channel (4) forming a store is intended to receive the objects (2) bearing on each other at their periphery.
- the channel (4) is of section rectangular right whose dimensions allow the objects (2) to be received with a slight clearance following a single stack.
- This channel (4) is open at its upper part for the manual manual introduction of the objects (2).
- a second channel (5) is intended to receive an expulsion piston (6) which has an external operating end (7) projecting from the handle (3) and an active internal end (8) suitable for cooperating with the object to kick out.
- the piston (6) is in the form of a blade of constant section whose end (7) carries a profiled piece (9) of actuation, curved and enlarged.
- the channel (5) is also of rectangular section, to allow axial sliding with clearance of the piston (6) between its two extreme positions.
- the blade of the piston (6) has, inside the channel (5) and over most of its length, a longitudinal cavity (10), closed at its two ends, which, on the one hand, receives a compression spring (11) abutting against the end (10a) of the cavity (10) adjacent to the outer end (7) and, on the other hand, is crossed, in the vicinity of its other inner end (8 ), by a fixed transverse spindle (12) secured to the outer wall (13) of the channel (5) and to the wall (14) separating the channels (4) and (5).
- the spring (11) is supported on the upper end (10a) of the cavity and on the spindle (12) to permanently urge the piston (6) towards its high inactive position shown in FIGS. 1 and 2.
- the long sides of the rectangular cross sections of the channels (4) and (5) are parallel.
- the first channel (4) opens, through a bent lower part (4a), into the second channel (5), in the region of the inner active part (8) of the piston (6) in the inactive position.
- the arrangement is such that, when an object (2A) is present at the lower end of the channel (5), under the piston (6), awaiting expulsion, as will be described below, the second object (2B) of the stack of waiting objects is located in the bent part (4a) of the channel (4), being pressed against a point on the periphery of the first object (2A), the lower part of the object (2B) being located at a level barely lower than that of the lower edge of the piston (6).
- the body (1) has a part intermediate (15) of greater width but substantially the same thickness as the handle (3).
- This intermediate part (15) constitutes the passage for passing objects and it contains the means for expelling and rotating said objects.
- lever (16) which is articulated on the body (1) around a pivot (17) with an axis perpendicular to the direction of advance of the objects in the device, this lever, on its face turned towards the axis (26) of the device, and in the direction of passage of the objects, having successively: a ramp (18) for abutting and stopping the objects one by one in the position of waiting for expulsion and forced separation of the lever, an active edge (19) of forced expulsion of the object, this edge being constituted by the lower end of the ramp (18), and a cam (20) cooperating with the object to impart to it its movement of rapid pivoting after, but preferably also during, its expulsion.
- the lever (16) is returned to its active internal deployed position, for which it constitutes a stop for the object to be expelled, by a spring (21) which acts between the wall of the intermediate part (15) and the lever itself. same, and which for this purpose is supported in the bottom of a slot (28) formed in the face of the lever furthest from the axis of symmetry (26).
- This active deployed position is bounded by a fixed stop constituted by a pin (22) carried by the body (1) and received in a cavity (23) formed in the lever (16), between the edge (19) of the end of the ramp (18) and the cam (20).
- the device according to the invention comprises two levers (16) arranged symmetrically with respect to the longitudinal axis (26) from the whole.
- the second lever (16) is identical to the first lever and, in the same way, cooperates with a spring (21) and a stop (22) which limits its return to the axis (26).
- a spring (21) and a stop (22) which limits its return to the axis (26).
- only one of the levers (16) is movable around the pivot (17), the second lever being fixed.
- the cams (20) are constituted by planar facets, parallel to each other and to the direction of expulsion of the object (2), but inclined relative to the tilting plane of the levers (16). These facets are spaced apart by a distance such that the object (2), when it is expelled towards them by the edges (19), comes into contact with the upper edges of the facets (2), by two points which are not diametrically opposite, this which causes on the object (2) a slight movement of first pivoting, as shown by the arrows (27) of FIG. 5, allowing it to pass between the two facets (20).
- the height distance between the edges (19) and the cams (20) is such that the object (2) , during expulsion, begins to cooperate with the cams by the facets thereof before having ceased to cooperate with the edges (19), that is to say before the levers (16) have returned to their rest position.
- the object (2) being expelled by the edges (19) which push it, comes to bear against the cams (20) which approach, which further increases the pivoting effect and prints on the object kinetic energy of pivoting without taking it from the kinetic energy of axial expulsion.
- the extreme insertion position of the piston (6) is defined by the abutment of the enlarged profiled part (9) against the top of the handle body (3). So that the piston (6) does not hinder the movement of the levers (16), and in particular their return to the active deployed position of FIG. 1, the extreme depressing position of the piston (6) and the profile of the lower edge of the active part (8) of the piston are such that, for the position of extreme insertion of the piston (6), the active part (8) does not interfere with the levers (16) when these are in the active deployed position .
- the lower end of the body (1) comprises means for coupling to a support, shown diagrammatically at (24), to facilitate or regulate the expulsion of the object (2), said support (24) constituting a support for the body (1) and defining the height at which the object is expelled relative to its surface of evolution (not shown) which receives it for the accomplishment of its rapid pivoting movement on himself.
- the support (24) therefore makes it possible, not only to launch the object (2) at a predetermined height with respect to this surface, but also to constitute a support for the user who only has to rest the lower end of the body on the support, which allows him to actuate the piston (6) without that the whole device moves in height or in inclination.
- the body (1) is extended by two end side tabs (25) which are pressed into the support (24).
- lever (s) (16) one or two leaf springs (30), cut and suitably shaped, which by their flexibility and their folds constitute by each of them the ramp means (18), for stopping the objects (2) in the expulsion standby position, the means (19) of forced expulsion of the objects one after the other, as well as the cam means (20 ) imparting to the expelled object its rapid pivoting movement around one of its axes.
- Each lever is in this variant replaced by a flat spring (30) whose blade is trapped at its two ends, respectively high and low, in housings, respectively (31) and (32).
- Each flat spring is folded and shaped so that, from its upper end to its lower end, it successively forms: a flat (33) substantially parallel to the axis of symmetry (26), a ramp (34) inclined up and down bottom, towards the axis (26), a recess (35) substantially orthogonal to the axis (26), a cam (36) capable of causing the expelled object to pivot on itself, and finally a return ( 37) whose end penetrates the housing (32).
- each leaf spring (30) is perpendicular to the vertical section plane of the device used for the representation of FIG. 6.
- the blade is shaped so that, like a cam (20), it is flat and inclined with respect to this cutting plane.
- the two cams (36) are, always like the cams (20), shaped so as to be parallel to each other and to the direction of expulsion of the object in the passage passage defined inside the body (15) .
- each spring (30) retracts towards an arm (15) of the device until the depressed object comes to bear, by its two diametrically opposite points, against the edges (40) each formed by a ramp (34) and a fold (35) (right half of Figure 6).
- edges have the same function as the edge (19), that is to say that under the effect of the permanent depression of the piston, when the object crosses the threshold of the edges (40), the springs (30 ) suddenly return to their active deployed position (left half of FIG. 6) and expel the object downwards, towards the cams (36), by their edges (40), under the effect of the abrupt elastic bringing together of the two blades .
- the expelled object then comes into contact with the two cams (36) which give it the desired rapid pivoting movement.
- each spring fulfills by itself three functions (waiting, expulsion, pivoting of the object), the pivots (17), the compression springs (21) and the stops (22) delimiting the active deployed position of the levers (16), these three means (17), (21) and (22) belonging by construction to each spring (30).
