- said actuating member 1430 is assembled in said base body 460.
- Said actuating member 1430 comprises fastening means 14301 to the body 460, for example a projection 14301 which penetrates into a hole 466 of the body 460.
- This projection 14301 is disposed on a first side, in particular above in the position shown in FIG. 5, of the stud 461 forming the axis of rotation A of the first counting element 410.
- Said actuating member 1430 also comprises a part of FIG. substantially rigid support 1436 disposed on a second side of said stud 461, in particular below in FIG. 5.
- Said support portion 1436 supports the actuating element 1435 which cooperates with the reservoir or can of the device on which the meter is assembled.
- Said support portion 1436 is connected to said projection 14301 by an elastically deformable portion 14341, 14342, 14343 surrounding said stud 461, and forming a spring.
- This elastically deformable portion may comprise two sides, advantageously approximately symmetrical, which connect said projection 14301 to said support portion 1436, respectively on each lateral side of said 461, in the position of Figure 5.
- Each side may comprise an upper deformable arc 14341 connected to said projection 14301 and a lower deformable arc 14343 connected to said support portion 1436. These arcs can be connected by a deformable baffle 14342.
- Said support portion 1436 extends towards said stud 461 by a flexible branch
- the actuating member 1430 substantially rectilinear supporting a pin 14310 adapted to cooperate with said first counting element 410 each actuation.
- the actuating member 1430 thus surrounds the first counting element 410, and in particular the first toothing 41 1 thereof.
- This implementation ensures particularly reliable actuation, in particular accurately defining the vertical and horizontal positions of the actuating member 1430, and ensuring optimal meshing of the pin 14310 in the first toothing 41 1.
- the terms "vertical” and “horizontal” used in the present description refer to the position of Figures 2 and 6, wherein the longitudinal axis of the body is substantially vertical and the axes of rotation substantially horizontal.
- the lower part of the actuating member 1430 has a downward movement generated by the support of the reservoir on the actuating element 1435.
- This downward vertical movement causes the pin 14310, carried by the branch 1431 which ensures the traction of this pin.
- This pin 14310 then drives the first counting element 410 in rotation by meshing with the first toothing 41 1.
- the shapes of the actuating member 1430 and the material constituting it cause that during downward vertical movement, the pin 14310 is driven in an equivalent vertical component movement.
- the branch 1431 is flexible to allow the escape of the pin 14310 behind the next tooth of the first toothing 41 1 during the ascent of the actuating member 1430 to return to its initial non-actuated position. This flexibility of the 1431 branch is adjusted by controlling its width in order to maintain sufficient rigidity for the pin 14310 causes the first counting element 410 on the rotation required to count a unit during the descent of the actuating member.
- the projection 14301 allows the vertical positioning of the actuating member 1430 in the body 460. In association with the upper end of the branch 1431 which cooperates with a stop 462 of the body
- this projection 14301 also ensures the precise position in height of the pin 14310 relative to the first toothing 41 1.
- the first counting element 410 is positioned in the body 460 by fitting onto the stud 461. This vertical positioning of the lug 14310 with respect to the first toothing 41 1 thus also defines the start of the driving stroke of the first element of FIG. counting 410 by this pin 14310.
- a second vertical guide branch 1432 is guided in vertical translation in the body 460, for example by cooperating with one or more appropriate projections 4650 and 4651.
- the second branch 1432 slides between two projections 4650 and 4651 of the body 460.
- This second branch 1432 ensures the horizontal positioning of the actuating member 1430, in particular during its movement. It also defines the horizontal initial position of the pin 14310 with respect to the first toothing 41 1.
- the projection 14301 remains fixed in the body 460, the arcs 14341 and 14343 are deformed, as well as the baffles 14342. These deformations remain in proportions which make it possible to avoid any plastic deformation and ensures in this way that the actuator 1430 returns to its shape and its initial position when the bearing on the actuating element 1435 is released.
- the dimensions of the arcs 14341, 14343 and 14342 baffles are also adjusted to ensure sufficient capacity to return to shape and initial position to take into account the constraints braking this return generated by the bending of the branch 1431 during the passage of the ergot 14310 behind the next tooth of the first set of teeth 41 1.
- the shapes of the connection zone 1439 between the support portion 1436 and the flexible branch 1431 are designed to ensure that when the actuating member 1430 is pulled vertically downward by pressing on the element actuation 1435, the deformation of the arches 14341 causes an inclination of the branch 1431 to the stud 461. This inclination of the branch 1431 helps the lug 14310 to mesh well with the first toothing 41 1 and to avoid unwanted premature escape of this engagement during the descent of the actuating member 1430.
- the deformable portion 14341, 14342, 14343 of the actuating member 1430 allows the continuation of the axial displacement of the tank until its end. Moreover, this system makes it possible to operate the meter before the start of the distribution of the product.
- An advantage of the meter of the present invention is that it allows the display in large size without increasing the size of the counter. In particular, the example shown allows for a counter of 200 doses, to display numbers (units on the one hand, tens on the other hand) having a height greater than 2 mm, preferably about 2.5 mm, and a width greater than 1.5 mm, preferably about 2 mm. This represents an increase in figure size up to 50% over existing meters.
- the indicator is adapted to indicate the number of doses remaining to be distributed so that the displayed figure decreases with each actuation.
- the opposite is of course also possible, namely a counter that counts the number of doses distributed.
- the counter of the invention by its components and the arrangement of these with respect to each other, thus makes it possible to produce a counter which can be pre-assembled to form a counter unit, and which presents in its pre-assembled state a very small thickness, typically less than or equal to 7 mm, preferably less than 6 mm and possibly even less than 5 mm.
- a very small thickness typically less than or equal to 7 mm, preferably less than 6 mm and possibly even less than 5 mm.
