Description

The present invention relates to a device for facilitating the shaping of type gift packages commonly called "florist gift package". These gift packages, which florists were the first to use, are increasingly popular with all professionals who distribute items that are often bought for sale. As non-limiting examples, these professionals are the decoration shops, the chocolatiers, the confectioners, the confectioners, the retailers of toys and games. They consist of wrapping the object to offer with one or more decorative leaves. Generally the outermost sheet is made of a transparent thin plastic film and the innermost sheet is a sheet of colored tissue paper. One of the advantages of this type of gift package is to allow the packaging of objects with complex shapes without having to place them in a parallelepiped box. Another advantage is that the color of the tissue paper determines the color of the gift package and the trader can more easily offer his customers the choice of the color of the package. This type of package is also used to pack confectionery or small gifts offered to guests of family ceremonies among which may be mentioned, as non-limiting examples, weddings, communions, anniversaries. In this case the envelope used is often tulle.

Traditionally these packages are made manually which presents several difficulties. Figure 1 shows the preparation: a sheet of tissue paper (2) is placed on top of a sheet of transparent plastic material (1) and the object (3) is placed on this assembly. Figure 2 shows the main difficulty of folding all the sheets (1) and (2) harmoniously on the object (3). The operator having only these two hands, there is always a part of the leaves which is not maintained and which falls on the work plan. To achieve bringing the sheets above the object according to Figure 3, the operator is still forced to crease the leaves which affects the final aesthetics. Moreover, it is also difficult to ensure that the folds of the leaves, once folded around the object, are regular. And finally when the sheets are folded according to Figure 3, the operator has more than one hand to put in place the ribbon bolduc (4) which is often twisted out of the reel. It so happens that the operator releases the leaves and is obliged to repeat the operation or at least be forced to tighten the leaves by pulling on the node of the bolduc which creases said bolduc and makes it less aesthetic. The shape of the final pack according to Figure 4 is often not regular and the bolduc (4) often looks like a string at the knot rather than a pretty wide ribbon as it should. To overcome these drawbacks, devices have been proposed, most often in a production workshop context. US6370840B2 discloses an apparatus for essentially placing a sheet around a floral assembly by vertically moving said floral assembly, said displacement being caused by the descent of a table portion on which is placed the floral assembly, the descent causing the sheet to coat said assembly. This device is bulky and is not easily portable. It is the object to be packaged that must be brought to the device. It is not a hand tool. It does not control the way the decorative sheets are pressed against the object and it does not adapt flexibly to an object of any shape.

US6892511 B2 discloses a device using pliers connected by wires to a structure placed above the object to be wrapped, said pliers serving to retain the edge of a wrapping sheet above and around the object to have them. hands free at the time of the introduction of the bolduc. This device does not save a lot of time of implementation, it is bulky and does not control the disposition of the folds of the sheet around the object. EP0356651 discloses a device using trays having a central opening, said trays being superposable, the sheets being placed between said trays. A hollow cylinder allows pushing the sheets through the central opening of the trays to form the package. The objects are introduced into the pack by the recessed part of the cylinder. There is provided a system for changing the diameter of the opening by changing a disk that is locked in the trays. This device does not easily adapt to any form of object. This would require storing many discs of various shapes and the pusher cylinder should be adapted to these discs.

The device according to the invention overcomes these disadvantages. It comprises in fact according to a first characteristic a crown provided with handles and forming tabs distributed over the perimeter of said ring and possibly spring means controlled by the user or possibly one or more mechanisms controlled by the user, said spring means or mechanisms allowing the user to move said tabs between a position where they are remote from the center of the ring, said position being called the opening position and a position where they are close to the center of the ring, said position being called closure position. Said tabs have at one end a shaping projection and their position can be locked by the user. Thus, with reference to FIG. 5, the user deposits the decorative sheet (s) (1) and (2), or a plurality of sheets, over the device and then deposits the object (3) 2940790 -3- to be packaged. in the center of the crown (5) of the device and over the leaves. Then with reference to Figure 6, it grasps said device by the handles and raises which has the effect of shaping the sheets around the object by the contact of said sheets with the forming end of the tabs. During this movement of raising the device around the object, the user controls the movement of the tongues via the mechanism or mechanisms (37) so that said tongues adjust said sheets (1) and (2) as close to the object (3). Referring to Fig. 7, when the object is completely covered by the sheets (1) and (2), the user controls the movement of the tabs via the mechanism (s) to close the package over the 'object. He has both hands free to put the bolduc (4) in good conditions. When the knot is finished, the user controls the movement of the tongues towards the crown to release the gift package. The device makes the operator realize a time saving of preparation and execution of the package which is a definite advantage for commercial activities around the gift, often seasonal in nature. In periods of high commercial activity, queues are generally located at the gift point of the stores. With reference to FIG. 8, said gift packs formed with the device according to the invention have more regular shapes, a more aesthetic knot and the sheets are not wrinkled. Among other advantages, it also becomes possible to easily produce packets with twisted folds by imparting a rotational movement to the device during the operation of raising said device around the assembly formed by the object (3) and the leaves (1) and (2). The device may be indispensable for packing tall objects by one person. It is light and not very bulky. It's an easy-to-keep tool at your fingertips.

Figures 80, 81, 82 and 83 show in perspective different types of accessories.

According to a particular embodiment, with reference to FIGS. 9 and 10, the device comprises a rigid or flexible ring (5). On the inner part of said ring are fixed, by rivets (7), tabs (6), in any number but generally greater than four. With reference to FIG. 10, this particular embodiment is represented with 35 tabs (6) regularly distributed over the ring (5). On the outer part of said ring (5) are fixed by rivets (7) two handles (8) and (8 ') substantially diametrically opposed. A cord (9) connects all the tabs bearing on small pulleys (10) integral with said tongues (6). In a nonlimiting manner the cord (9) may be of the type used for tennis racket ropes. One of the ends of said cord (9) joins a mechanism (37) with 5 geared motor, said mechanism being able to be housed in a handle (8) and protected by a cover (11). The other end of the cord (9) can be either simply fixed to another handle (8 '), or connected to another mechanism (37') with a geared motor which can be integrated with said handle (8 ') and protected by a hood (11 '). A pushbutton (12) allows the user to control the gearmotor mechanism (37) and a non-return lever (13) in combination with a ratchet wheel (14) to lock a position tongues or releasing said position under the impetus of the spring means (15). With reference to FIGS. 11, 12 and 13, the tabs (6) each comprise: • a zone forming a spring (15) of the blade type, • a portion (16) for shaping packets, • an appendix (17) ) avoiding the pinching of the sheets by overlapping the adjacent tab, • a pulley (10) freely mounted on an axis (18) crimped into an outgrowth (19) of the shaped portion (16) of the tongues (6).

In a nonlimiting manner, the spring portion (15) may be spring steel and the forming portion (16), appendix (17) and protrusion (19) assembly may be made of plastic material overmolded on the spring portion (15). As shown in Fig. 11, the shaping parts (16) and appendages (17) may be slightly inclined with respect to the axis of the spring portion (15) to facilitate the overlap of the neighboring tongue during movement. FIG. 12 shows a tongue where the cord (9) makes two passes in the non-limiting configuration shown in FIG. 10. With reference to FIGS. 10 and 14, a mechanism (37) is housed for example in a handle (8) shown Open hood in FIG. 10. A second geared motor mechanism (37 ') may possibly be housed in another handle (8'). Referring to Figures 10 and 14, a mechanism (37) integrated in a handle (8) comprises a geared motor (25) of power and reduction ratio adapted. It also comprises, integral on the same axis (20), a coil (21), a toothed wheel (22) and a ratchet wheel (14). Said axis (20) is free to rotate relative to the handle (8). An anti-return lever (13), articulated about an axis (30) integral with the handle (8), forces the ratchet wheel (14) to rotate in one direction only by virtue of the spring (23) which press the lever (13) on the ratchet wheel (14). The cord (9) wraps around the bobbin (21). The toothed wheel (22) is driven by a pinion (24) integral with the shaft of a geared motor (25). The geared motor (25), integral with the handle (8), is powered by a source of electrical energy (26) by pressing the user on a push button (12). The cord (9) comes out of the handle possibly bearing on pulleys (27).

From the open position when the shaping parts (16) of the tongues (6) are remote from the center of the ring gear (5), the user actuates the push button (12) which feeds the gear motor (25). ) which rotates the pinion (24), the toothed wheel (22), the coil (21) and the ratchet wheel (14) in the direction indicated by the arrow (28). This has the effect of winding the cord (9) around the pulley (21), said cord driving the shaping parts (16) of the tongues (6) to the closed position along a path (29) shown for one of the tabs (6) in Figure 10. Figure 15 shows, without limitation, an electrical diagram for controlling the gearmotor (25). To return to the open position, with reference to FIG. 14, the user actuates the anti-return lever (13) which releases the ratchet wheel (14) and the axis (20) is then driven into the opposite direction of the arrow (28) under the effect of the cord (9), itself pulled by the tongues (6) under the effect of their spring blade portion (15). FIG. 16 shows the device according to the particular embodiment described above, said device used to package objects (3) of any shape by adapting it to said objects by action of the user on the handles (8) and ( 8 '), in a nonlimiting manner according to the arrows (31) and by using the flexibility of the ring (5) which can be made for example of flexible plastic material in a single injection molding operation. The complete implementation of the device has already been described previously with reference to FIGS. 5 to 8. According to one variant of the particular embodiment described above with reference to FIGS. 9 to 15, the (the) geared motor mechanism (37) pulling a cord (9) is replaced by a manual hoist mechanism (41) integrated in a handle (8) and illustrated with reference to FIGS. 17 and 18. A hoist-type motion reduction system 30 is used with at least three pulleys (32) between which runs the rope (9), said pulleys being distributed on two axes (33) and (34), the shaft (34) being integral with a sliding handle (35) sliding on a handle (8); ) and the axis (33) being integral with said handle (8). The hoist effect allows the user to put the device in the closed position in a single pulling motion on the sliding handle (35) while a lever pawl (36) blocks the return movement to the open position. said lever pawl (36) being mounted on the sliding handle (35) and articulated about the axis (38) integral with said sliding handle and urged by a spring (39) to bear against a shape with anti-return teeth (40) secured to the handle (8). Said return movement to the open position can be done under the motor effect of the spring means (15) only when the user presses on the lever of the lever pawl (36) to release the sliding lever (35).

According to another variant of the embodiment described above with reference to FIGS. 9 to 15, the mechanism (s) pulling the cord (9) is replaced by a manual mechanism with cumulative movement (42) integrated into a handle (8). and illustrated with reference to Figures 19 and 20. To have the ability to wind around a coil (21) the length of string (9) required, a sliding handle (35) 10 sliding on a handle (8) allows, by movements back and forth along the directions 1 and 2 of the boom (43), accumulate displacements via a ratchet wheel (14) integral with an axis (20). Said axis (20) also carries a coil (21) and is free to rotate relative to the handle (8). Said ratchet wheel (14) is rotated in the direction of the arrow (28) by an anti-return toothing lever (46) mounted on the sliding handle (35) and articulated about an axis (47). ) and pushed by a spring (23 ') to bear on the ratchet wheel (14). A lever anti-return gear (13) mounted on the handle (8) and articulated about an axis (30) and pushed by a spring (23) bears on the ratchet wheel (14) to block the rotation of said wheel ratchet in the opposite direction of the arrow (28).

When the user pulls the sliding lever (35) in direction 1 of the arrow (43), the anti-return toothing lever (46) drives the ratchet wheel (14) which in turn drives the reel (21) and the cord (9) and this until the sliding handle (35) abuts on the handle (8), then the user releases the sliding lever (35) which is returned to its initial position by return springs (48) in the direction 2 of the arrow (43), the ratchet wheel (14) being retained during this phase by the anti-return lever (13). The user can again pull the sliding handle (35) and so on until the closed position. To return to the open position, the user simultaneously actuates the anti-return lever (13) and the anti-return toothing lever (46), which releases the ratchet wheel (14) driven by rotation in the opposite direction of the arrow (28) under the action of the spring means (15). The cord (9) out of the mechanism possibly bearing on a pulley (27). The mechanism is housed in a handle (8) and protected by a cover (11). The sliding handle (35) is equipped with a closing cap (50). Figure 19 is shown with covers (11) and (50) removed. A second cumulative movement mechanism (42 ') can be integrated with another handle (8') and in this case it is mounted to act in the same direction as the first mechanism by pulling on the cord (9) when the user 2940790 -11- pulls on the sliding handle (35 ') of said second mechanism. According to another variant of the embodiment described above with reference to FIGS. 9 to 15, the (the) geared motor mechanism (37) pulling the cord (9) is replaced by a geared motor with a disengageable current brake (51). illustrated with reference to FIGS. 21 and 22. With reference to FIG. 21, represented as a cover removed, the geared motor with a disengageable current-brake (51) is integrated in a handle (8) or (8 ') and is integral with said handle. It is powered by an electric power source (26) via a push button (12), the brake part being active when the gear motor is not powered. The output shaft of said geared motor 10 is directly integral with a grooved pulley (53) in which the cord (9) is wound, which in this case and in a nonlimiting manner may be a small strap of rectangular section of slightly width. less than that of said groove. With reference to FIG. 22, a possible structure of the geared motor with a power-down brake (51) is illustrated in a nonlimiting manner.

With reference to said figure, the electric motor part consists of a housing (54) in which a stator (55) is integrally mounted, said housing being closed by a cover (56) bearing friction surfaces (61). An axis (57) is mounted on bearings (58) centered in the housing (54) and the cover (56), said axis (57) carrying, inside the motor, a rotor (59) and a disc ( 60) and outside the motor, on the cover side (56), a stop (62) integral with the outer ring of a bearing (63) mounted on said pin (57), said outer ring being pressed against the stop (62) by a washer (64). The inner ring of the bearing (63) is clamped on the shaft by the washer (65) so that the stop (62) is decoupled in rotation relative to the axis (57). A spring (66) compressed between the washer (64) and the hood (56) both to move said washer away from said hood so that in the event of a power failure, the motor is not powered, the disc (60) rubs on the surfaces of friction (61) and the rotor (59) is axially offset relative to the stator (55). When the motor is energized, the magnetic forces recenter the rotor in the stator which moves the disc (60) away from the friction surfaces (61) and allows the rotation of the motor and the gear (67), not detailed in FIG. 22 , causing rotation of the grooved pulley in which the rope (9) is wound, said rope driving the tongues (6) to the closed position. A power off activates the brake and locks the current position. From a locked position, the user can disengage the brake by operating a lever (68) hinged about an axis (69) mounted crimped into a yoke (70) integral with the cover (56). Said lever, actuated along the arrow (71), pushes the stop (62), which releases the pin (57) which is then rotated under the action of the cord (9), itself pulled towards the opening position by the tongues (6) under the action of their spring means (15). A piece (72) limits the movement of the lever (68) in the opposite direction to the arrow (71). According to another particular embodiment with reference to FIGS. 23, 24, 25, 26 and 27, handles (8) and (8 '), substantially diametrically opposed, and tabs (6), in any number, constitute parts the ring 5 (5) rigid or flexible, this especially in the case where said ring, said handle and said tabs are made of plastic in a single injection molding operation. Referring to Figure 25 the tongue portions (6) are inclined to facilitate their overlap. With reference to FIGS. 26 and 27, the cord (9) passes behind a single lug (19) also obtained during said single injection molding operation. This embodiment is presented, in a nonlimiting manner, with the type of mechanism (37) already described in the embodiment with reference to FIGS. 9 to 15, but may also be equipped with all the mechanism variants (41), ( 42) and (51) discussed above with reference to Figures 17 to 22 and more generally of any cord winding mechanism.

Referring to Figs. 30, 31 and 32, the shaping portion (16) has a recess (79) for receiving the appendage portion (17) of a neighboring tab and thereby avoiding pinching effect when the (the) sheets (1) and (2) are folded down along the object (3) with reference to FIG. 6. With reference to FIGS. 30, 31 and 32, the recess (79) may be equipped with two rollers (80). ) free in rotation about the axes (81) crimped into the tongue, said rollers serving to support the appendix (17) of the adjacent tongue to facilitate its progression during the movement. The side opposite to the shaping part (16) of the tongues (6) also has a recess (82) to facilitate the passage of the rope (9) resting on pulleys (10) mounted free around the shafts (18). ) crimped into the tabs (6) at the location of said opposite side. Referring to Figure 30, the spring portion (15) is also recessed to let the rope (9). Figure 29 shows the mechanisms housed in each handle (8) and (8 '), said handles shown respectively hood (11) and (11') removed. With reference to FIGS. 29, 33 and 34, this embodiment is presented, in a nonlimiting manner, with the type of mechanism already described in the embodiment with reference to FIGS. 9 to 15 but may also be equipped with all mechanism variants (41), (42) and (51) discussed above with reference to FIGS. 17 to 22 and more generally of all rope winding mechanisms. According to another particular embodiment with reference to Figures 35, 36, 37, 38 and 39, tabs (6), in any number, have no spring portion. The (each) spring means enabling them to return to the open position is, in a nonlimiting manner, a wire spring (84) wound around rings (85) and bearing firstly on an area of a crown (5). ) rigid or flexible with reference to Figures 35, 36 and 39 and secondly on the (each) tabs (6). The tongues (6) and the rings (85) are mounted free to rotate about the axes (87) which are crimped in the ring (5) made in two parts. With reference to FIGS. 35 and 36, this embodiment is represented with the mechanism previously described with reference to FIGS. 19 and 20, but may also be equipped with all the previously described variants of mechanism (37), (42) and (51). with reference to Figures 10, 14, 15 and 17 to 22 and more generally of all rope winding mechanisms.

According to another embodiment with reference to FIGS. 44 to 50, the movement of a geared motor (25) is transmitted to tongues (6), in any number, by gears (95) and (96) mounted on arms (97), interconnected by axes (98). With reference to FIG. 48, said arms (97) have a clevis-shaped end and the other end in the form of a tenon, said tenon fitting into the clevis of the adjacent arm, the axis (98) inserting freely in the center of the clevis - tenon assembly to create the joint. With reference to FIGS. 44 and 47, in particular the enlarged top view of a hinge, a blade-like spring (99) positioned and retained in the arms (97) through slots (100) makes the hinge elastic to the deformation in rotation, so that the set of articulated arms forms a crown (5) deformable by action on handles (8) and (8 '). Said handle (8) and (8 ') are integral with two particular arms (102). The handle (8) integrally integrates the geared motor (25) and another geared motor (25) can optionally be integrated with the handle (8 '). With reference to FIG. 48, the gears (95) are freely rotatably mounted on axes (103), said axes (103) being crimped into arms (97) and (102). The 5 gears (96) located at the joints are mounted crimped in axes (98) to transmit the rotational movement to the tongues (6), themselves crimped at the other end of said axes (98). Referring to Figure 40 and in particular to the enlarged view of the inner portion of the handle, the geared motor (25) of the drive mechanism transmits the movement 10 to the gears via a pinion (104). The gears (95) and (96) are arranged so that during the movement, the tongues (6) all pivot towards the center of the crown together. The arms (102) and (105) are different from the arms (97). With reference to FIG. 49, the arms (105) have an axis (98) which is not at a joint, the gear (96) and the tongue (6) therein being crimped into said shaft (98) rotatably mounted in an arm (105) and the articulation at the arms (102) and (105) is formed with an axis (103) rotatably mounted in the tenon of the arm (102) and crimped into the clevis of the arm (105). This arrangement makes it possible to dissociate partly on the one hand the rotational movement of the gears due to the deformation of the ring (5) formed by the arms (97), (102) and (105) and on the other hand the movement generated by the mechanism (s). With reference to FIG. 44 and to a possible electric power supply diagram shown in FIG. 50, the geared motor (25) is powered by an electric power source (26) and is controlled by a switch (106) having a "Stop" rest position, a "Close" position to be maintained by the user, and another "Open" position to be maintained by the user. Referring to Figure 44 and in particular to the enlarged detail view, the locking of the position of the tabs can be provided by a small lever (107) sliding in the cover (11) to come block the axis (109) of the geared motor. (25) at the pins (110) integral with said axis (109) as shown in Figures 45 and 46.

With reference to Figures 44 and 47, the gears may be protected by covers (111). As for the other embodiments already described above, the movement can be generated by a single mechanism in a single handle or by several mechanisms at the rate of one or more per handle. According to a variant of the embodiment described above with reference to FIGS. 44 to 50, the tongues (6) are mounted in the axes (98) and (103) with a rotation clearance of a few degrees to allow a greater capacity of the crown (5) to be deformed. According to another variant of the embodiment described above with reference to Figures 44 to 50, the mechanism rotating the pinion (104) is replaced by a mechanism (49) manual cumulative movement and integrated spring. Said mechanism rotating the pinion (104) is illustrated with reference to Figures 51 and 52. With reference to these figures, a sliding handle (35) sliding on a handle (8) allows, by movements back and forth following directions 1 and 2 of the arrow (43), accumulate displacements via a ratchet wheel (14) integral with an axis (20 '). Said ratchet wheel (14) is rotated in the direction of the arrow (28) by an anti-return toothing lever (46) mounted on the sliding lever (35) and articulated about an axis (47). ) and pushed by a spring (23 ') to bear on the ratchet wheel (14). A lever with anti-return teeth (13) integral with the handle (8) and articulated about an axis (30) and pushed by a spring (23) resting on the ratchet wheel (14) to block the rotation of said wheel ratchet in the opposite direction of the arrow (28). When the user pulls the sliding handle (35) in direction 1 of the boom (43), the anti-return toothing lever (46) drives the ratchet wheel (14) which in turn drives the pinion (104) and the toothed wheel (95) and this until the sliding lever (35) abuts the handle (8), then the user releases the sliding lever (35) which is returned to its position initially by the return springs (48) in the direction 2 of the arrow (43), the ratchet wheel (14) being retained during this phase by the anti-return lever (13) which locks the position. The user can again pull the sliding handle (35) and so on until the closed position. To return to the open position, the user actuates concomitantly with the anti-return lever (13) and the non-return toothing lever (46), thereby releasing the ratchet wheel (14) which is then driven into position. rotation in the direction opposite to the arrow (28) under the action of a spring means integrated in the mechanism and which may be in a nonlimiting manner a spiral spring (112) whose end is integral with the axis (20). ') and the other end is secured to the handle (8) via a pin (113). According to another variant of the embodiment described above with reference to FIGS. 44 to 50, the mechanism is replaced by a gearmotor (114) equipped with a non-disengageable brake by the user illustrated with reference to FIGS. and 54. Fig. 53 shows said mechanism integrated in a handle (8). A possible structure, in a nonlimiting manner, of the gearmotor with a non-disengageable current-canceling brake (114) is illustrated by a cross-sectional view with reference to FIG. 54. With reference to said figure, the output axis (52) ) of said geared motor (114) is directly integral with the pinion (104). The electric motor part consists of a housing (54) in which a stator (55) is integrally mounted, said housing being closed by a cover (56) bearing friction surfaces (61). An axis (57) is mounted on bearings (58) centered in the housing and the cover, said axis (57) carrying, inside the motor integrally a rotor (59) and a disc (60) and at the outside the motor, on the cover side (56), a stop (62 ') integral with the outer race of a bearing (63) mounted on said shaft (57), said outer ring being pressed against the stop (62') by a washer (64). The inner ring of the bearing (63) is clamped on the shaft by the washer (65) so that the stop (62 ') is decoupled in rotation with respect to the axis (57). Said abutment (62 ') is locked in translation by lugs (115) integral with the cover (56). A spring (66) compressed between the washer (64) and the hood (56) both to move said washer away from said hood so that in a situation of lack of power, motor not powered, the disc (60) rubs on the surfaces of friction (61) and the rotor (59) is axially offset relative to the stator (55). The gearmotor (114) is controlled by a switch (106) according to a possible electric diagram shown in FIG. 50. When the motor is powered in the open or closed position of the switch (106), the magnetic forces refocus the rotor in the stator which moves the disc (60) away from the friction surfaces (61) and allows rotation of the motor and the gear (67), not detailed in Fig. 54, causing the pinion (104) to rotate to the selected position. A power off, "off" position of the switch (106), actuates the brake and locks the current position 20 of the tabs (6) of the device according to this embodiment so that according to this variant with reference to FIGS. 44 to 49, the position locking system using the lever (107), the pins (110) and the axis (109), the said locking system is no longer necessary and can be omitted according to the said variant using a geared motor with a power failure brake (114).

According to another embodiment with reference to FIGS. 55 to 59, the movement of a geared motor (25) integral with a handle (8) is transmitted to any number of tongues (6) by a toothed belt (118). ) which surrounds the perimeter of a rigid or flexible crown (5), said toothed belt being supported on the tongues (6) at a portion (120) of said toothed wheel tongues 30 illustrated with reference to the figures 56 and 58. Another geared motor (25) can be integrated with another handle (8 '). Referring to Figure 59, the tabs are mounted free to rotate about the axes (122) mounted crimped in the ring (5) having an upper part and a lower part. The geared motor (25) is controlled by a switch (106) according to a possible electrical diagram shown in FIG. 50.
