Definitions
- the present invention relates to a duo distributor comprising two pumps, namely a first pump provided with a first actuating rod movable axially over a first maximum stroke, and a second pump provided with a second actuating rod movable axially over a second defined maximum stroke.
- the distributor also includes a common pusher movable axially and acting axially and directly on the first actuating rod to drive it on its first maximum stroke.
- duo dispensers with adjustable doses by varying the stroke of the actuating rods by limiting the stroke of the actuating rod, only a partial dose is distributed. We can thus vary the proportion of the two doses delivered. This is not the objective of the present invention.
- duo distributors which use a common pivoting or rotating pusher, such as that of document WO2019208335A1.
- a requirement of the present invention is that the common pusher moves only axially, with no pivoting or rotating component.
- the major aim of the present invention is to vary in an overall reducing tendency the speed of the actuating rod having the shortest stroke relative to the speed of the other actuating rod having a longer stroke, and this with a common pusher purely axial movement.
- the goal is not to reduce one dose relative to the other, nor to make up for a difference in stroke by an initial or final dead stroke, but to activate the two rods with different speeds.
- the present invention proposes a duo distributor comprising two pumps, namely:
- the distributor comprising a common pusher movable axially and acting axially and directly on the first actuating rod to drive it over its first maximum stroke , characterized in that:
- the distributor further comprises reduced speed transmission means acting between the common pusher and the second actuating rod to transmit the axial thrust force of the common pusher to the second actuating rod with a reduced speed of the second rod actuation relative to that of the first actuation rod.
- These reduced speed transmission means can also be described more simply as a speed reducer of one rod relative to the other.
- these reduced speed transmission means allow simultaneous movement of the two actuating rods, but with different non-zero speeds.
- the rod having a stroke corresponding to half of the other rod may move half as fast as the other over the entire travel of the two rods.
- an actuating cam with an irregular or complex profile will generate a speed V2 of movement of the actuating rod which is not proportional to the speed V1 of movement of the other actuating rod.
- V2 f(p) x V1
- p being the slope of the contact surface and with f(p) varying between 0 and 1.
- f(p) is locally constant, that is to say with a regular or linear profile.
- Many combinations are possible, combining consecutive speed phases which can be proportional and variable.
- the first and second maximum strokes can be carried out both entirely and simultaneously by axial support on the common pusher.
- the speeds of the two actuating rods can be proportional and/or variable.
- the reduced speed transmission means comprise a mobile element which rotates around a vertical axis of rotation secured to the common pusher.
- the movable element comprises: an axis housing for the vertical axis of rotation of the common pusher, a rotation drive member which comes into sliding contact on a fixed curved inclined ramp, and an actuation cam which comes into sliding contact with the second actuating rod.
- the actuation cam comprises a contact surface engaging with the second actuation rod, this contact surface being at least partially inclined.
- this contact surface can also be partially flat. Plane and inclined profiles can follow one another.
- the mobile element can be produced in a single piece.
- the mobile element can be rotated towards a starting position by a return spring, which is advantageously made in one piece with the mobile element.
- the advantage of this first embodiment lies in the fact that there is only one moving part between the common pusher and the fixed part of the distributor, namely the mobile element, which moreover can be in one piece, including with the return spring. It is enough to form the common pusher with a vertical axis of rotation, for example in the form of a small pin pointing downwards. As for the curved inclined ramp, it can be formed at the fixed part of the distributor in the form of an obliquely truncated cylinder segment.
- the mobile element is the only part to be manufactured and mounted between the common pusher and the fixed part of the distributor, which makes this first embodiment particularly advantageous.
- the reduced speed transmission means may comprise two articulated levers which are connected together at a common junction, a first lever being articulated on a bearing or pivot secured to the common pusher and a second lever which is articulated on a bearing or fixed pivot, the common junction being provided with an actuation cam which comes into contact with the second actuation rod.
- the actuation cam can be connected to one of the two levers, preferably in a single piece.
- the actuation cam may have a regular and/or irregular profile to induce proportional and/or variable speed phases, as mentioned above.
- the reduced speed transmission means may comprise: a toothed wheel mounted on a fixed horizontal axis of rotation, a toothed axial rod secured to the common pusher and engaging with the toothed wheel to cause it to rotate, and an actuation cam secured to the toothed wheel and coming into contact with the second actuation rod.
- the actuation cam can have a regular and/or irregular profile to induce proportional and/or variable speed phases, as mentioned above.
- the toothed axial rod can be made in one piece with the common pusher in the form of an elongated tab which points downwards and which is provided with teeth on one of its two vertical edges.
- the fixed part of the distributor can form two bearings for the horizontal axis of rotation of the toothed wheel.
- the reduced speed transmission means although they implement very different components, all interact with the common pusher and the fixed part of the distributor to move an actuation cam which presses on the second actuating rod, while the common pusher presses directly and axially at the same time on the first actuating rod. It must be borne in mind that the reduced speed transmission means only act when the first actuating rod is actuated by the common pusher. The second actuating rod therefore moves simultaneously with the first actuating rod, but with an overall reduced speed, even if the two rods can momentarily move at the same speed over a limited stroke.
- Figure 1 is a cut-out perspective view of the upper part of a distributor according to a first embodiment of the invention, in the rest state,
- Figure 2 is a view similar to that of Figure 1 with the distributor in the activated state
- Figures 3 and 4 are vertical cross-sectional views of the distributor of Figure 1 along perpendicular planes
- Figure 5 is a vertically cut perspective view of a distributor according to a second embodiment of the invention, in the resting state,
- Figure 6 is a view similar to that of Figure 5 of the distributor in the activated state
- Figure 7 is a cut-out perspective view of the upper part of a distributor according to a third embodiment of the invention, in the rest state
- Figure 8 is a view similar to that of Figure 7 of the distributor in the actuated state.
- Figure 9 is a vertical cross-sectional view through the distributor of Figure 7.
- the dispenser comprises common or similar constituent elements.
- the distributor includes two pumps P1 and P2 which are mounted on respective tanks (not shown).
- the detailed design of pumps P1 and P2, as well as the reservoirs, is not critical to the present invention. You simply need to know that the pumps P1 and P2 are fixedly mounted on their respective tanks and that only their actuating rods P11 and P21 can be moved axially back and forth. This is a completely classic design for a manual pump in the field of cosmetics, pharmacy or even perfumery.
- the actuating rods P11 and P21 are returned to the rest position by return springs, which can be internal, as in pump P1, or external, as in pump P2.
- the pumps P1 and P2 are different from each other and more particularly the respective maximum axial strokes of the two actuating rods P11 and P21 are different.
- the maximum axial stroke of the actuating rod P11 is greater than that of the actuating rod P21. It is therefore necessary to move the actuating rod P11 over an axial distance greater than the actuating rod P21 to distribute the full dose of fluid product. You should know that when different pumps are used in a duo distributor, the maximum strokes of the two actuating rods of the two pumps are rarely identical.
- the technical problem underlying the invention is to actuate these two actuating rods P11 and P22 simultaneously, which requires reducing the speed of movement of the shorter actuating rod P21 relative to the longer P11.
- This technical problem is all the more present as the distributor of the invention comprises a common pusher which is movable axially along an axis which is parallel to the axes of movement of the two actuating rods P11 and P21.
- the common pusher moves purely axially without any rotating or pivoting components.
- the common pusher B is connected directly and axially to the actuating rod P11 by a connection sleeve B11.
- the common pusher B is connected to the actuating rod P21 by a sliding connection sleeve B21.
- connection sleeve B11 communicates through a conduit B12 to a distribution orifice B13.
- connection sleeve B21 communicates through a conduit B22 to another distribution orifice B23.
- the sleeves B11 and B21 could also communicate with a common distribution orifice.
- reduced speed transmission means act between the common pusher and the actuating rod P21 so as to modulate the speed of movement of the actuating rod P21 relative to that of the other rod. actuation P11.
- the reduced speed transmission means make it possible to reduce the speed of movement of the actuating rod P21 relative to the other actuating rod P11.
- These reduced speed transmission means comprise a mobile element 1 of relatively complex design.
- This mobile element 1 firstly comprises a plate 11 which extends substantially horizontally, that is to say perpendicular to the axes of movement of the actuating rods and the common pusher B.
- This plate 11 rotates around a vertical or axial axis of rotation B12 formed by the common pusher B.
- the plate 11 forms an axis housing 12.
- the plate 11 is provided with a return spring 13 which allows the plate 11 to be returned to a rest position.
- the return spring 13 acts between the plate 11 and the common pusher B and can advantageously be produced in one piece with the plate 11.
- the movable element 1 comprises a rotation drive member 14, which comes into sliding or sliding contact on a curved inclined ramp P14, which is formed by the fixed part of the distributor.
- the movable element 1 can for example be in the form of a rod which extends downwards from the lower face of the plate 11.
- the free end of the rod 14 can be inclined to facilitate its sliding on the curved inclined ramp P14.
- the movable element 1 also includes an actuation cam 15 which extends laterally from the plate 11. This actuation cam
- the actuation cam 15 includes a contact surface intended to come to bear on the actuating rod P21.
- the actuation cam 15 also includes an upper bearing surface 153 on which the connection sleeve B21 bears. More precisely, we can see in Figure 3 that the sleeve B21 ends in a tube B211, which is slidably engaged in the actuating rod P21. In other words, the actuating cam 15 is sandwiched between the connecting sleeve B21 and the actuating rod P21 extending around the tube B211.
- the contact surface of the cam 15 comprises several segments, in particular a horizontal segment 151 and an inclined segment 152. This is only one embodiment not limiting: we can of course imagine more segments or, on the contrary, a single segment.
- the actuating rod P11 By axial pressure on the common pusher B, the actuating rod P11 will be moved. It is the same for the actuating rod P21, the axial support force of which is transmitted by the connecting sleeve B21 and the actuating cam 15, the horizontal segment 151 of which presses directly on the actuating rod P21.
- the axial movement of the pusher B also has the effect of rotating the movable element 1 around the axis B12 under the stress of the actuation cam 14 which slides on the curved inclined ramp P14. As a result, the actuation cam 15 will move horizontally so as to bring its inclined segment 151 into contact with the actuation rod P21. This is shown in Figure 2.
- the segment 152 Since the segment 152 is inclined, the distance between the connecting sleeve B21 and the actuating rod P21 is gradually reduced, which has the effect of reducing the speed of movement of the rod of displacement P21 relative to that of the other actuation P11.
- the inclined segment 152 has a constant slope, so that the speed of movement of the actuating rod P21 is proportional or linear to that of the actuating rod P11. It would have been different with an inclined segment having a non-constant slope, for example convex or concave or even wavy.
- the actuating rod P21 is moved with two distinct phases, namely an initial phase, during which its speed of movement will be identical to that of the actuating rod P11 (corresponding to the flat segment 151) and a second phase, during which its speed of movement is reduced compared to that of the actuating rod P11, but with a constant ratio (corresponding to the inclined segment 152). It is then easily understood that it is possible to adapt the speed of movement of the actuating rod P21 relative to that of the other actuating rod P11 by adjusting the configuration of the contact surface (151, 152) of the actuating cam 15.
- the rotation speed of the mobile element 1 around the axis B12 can also be modulated by varying the slope of the curved inclined ramp P14 or the upper support surface 153.
- the common pusher B' may be similar to the common pusher B of the first embodiment, except that the axis of rotation B12 has here been replaced by a first horizontal axis bearing B23. At the fixed part of the distributor, the curved inclined ramp P14 is replaced by a second horizontal axis bearing B24.
- the two pumps P1 and P2 are identical to that of the first embodiment.
- the reduced speed transmission means 2 of this second embodiment comprise two levers 21 and 22 which are movable relative to each other, while being connected by a common junction 20.
- the first lever 21 comprises one end 23 which rotates in the axle bearing B23.
- the second lever 22 includes an end 24 which rotates in the second axle bearing B24.
- the second lever 22 is provided with an actuation cam 25 which forms a contact surface 251 which comes into contact with the actuation rod P21, which has a maximum stroke less than that of the other actuation rod P11 .
- the contact surface 251 can be perfectly circular, or on the contrary profiled like that of Figures 5 and 6. A circular contact surface will induce a linear movement of the actuating rod P21 relative to the other rod P11.
- the profiled contact surface 251 of Figures 5 and 6 induces a non-linear or non-proportional displacement relative to the rod P11. Consequently, here again, it is possible to modulate the speed of movement of the actuating rod P21 relative to that of the other actuating rod P11, by varying the shape of the contact surface 251.
- the pumps can be identical to the first two embodiments of the invention.
- the common pusher B” can have a similar design, with the exception of the rotation axis B12 or the axis bearing B23 which is here replaced by a toothed axial rod 31 which extends downwards.
- These transmission means 3 also include a toothed wheel 32 which is mounted on a horizontal axis of rotation 33 received in a fixed axis bearing P33 formed by the fixed part of the distributor.
- These transmission means 3 also include two actuation cams 35 which engage with the actuation rod P21, and more particularly with a rim P211 of the actuation rod.
- the toothed rod 31 is meshed with the toothed wheel 32, so that an axial movement of the common pusher B” has the effect of rotating the toothed wheel 32 around its axis 33, thus inducing a pivoting movement of the two cams actuation 35 which act directly on the actuation rod P21.
- the contact surface 351 of the two actuating cams 35 can be profiled to modulate the speed of movement of the actuating rod P21 relative to that of the other actuating rod P11 which is directly actuated by the common pusher B”.
- the two actuating rods P11 and P21 can be moved simultaneously over their entire respective travel, but with different movement speeds. However, it cannot be ruled out that the movement speeds of the two rods could be identical over part of their travel. But in the end, we can say that the speed of movement of the actuating rod P21 is reduced compared to that of the other actuating rod P11.
- the actuation speeds of the two rods can be proportional or linear with regular contact surfaces, or on the contrary non-proportional or dissimilar with complex contact surfaces.
- the first embodiment with its mobile element 1 has the advantage that there is only one part to add to the duo distributor: the rotation axis B12 and the ramp inclined curved P14 which can be made in one piece with their respective component.
