FIG. 2 shows a radial dial-up/dial down mechanism with separate keys for dial-up and dial-down,
FIG. 5 shows an injection device having an integrated axial dial-down mechanism.
A radial solution is shown in FIG. 1. FIG. 1 a shows a rotatable inner part 2 biased against a fixed outer part 1. The biasing force is provided by a torsion spring (not shown) in the counter-clockwise direction. The inner part 2, which is rotatable around a center axis 6, has one or more flexible arms 3 adapted to engage with the edges 5 in the fixed outer part 1. FIG. 1 b shows the arrangement of FIG. 1 a with a rotatable disc 7 (hatched region) placed on top of the inner part 2 and outer part 1. The disc 7 has an opening 8. The edges defining the opening 8 constitute dial-up and dial-down cams. A pick-up key 4 attached to, or integrated with, the flexible arm 3 operates as a cam follower when the disc 7 is rotated relative to the outer part 1.
FIG. 2 shows an exploded drawing of the radial embodiment of the dial-down mechanism according to the present invention. The main difference compared to the embodiment shown in FIG. 1 is that the embodiment of FIG. 2 applies different pick-up keys for dial-up (pick-up key 11) and dial-down (pick-up key 12). The dial-up key 11 engages with track 15 of the disc 14, whereas dial-down key 12 engages with track 16 of the disc 14. Tracks 15 and 16 are formed as through-going openings or indentations in a planar surface of the disc 14. The dial-up tracks 15 take the form of curved tracks whereas the dial-down tracks 16 are V-shaped. An obvious alternative to the V-shape is a rectangular shape. It should be noted that the general idea is that the dial-up tracks 15 should be capable of transferring a momentum to a torsion spring 18. In the same manner, the dial-down tracks 16 should be capable of releasing the dial-down keys (and thereby release energy) in case the disc 14 is rotated just a few degrees relative to the nut 10.
FIG. 5 shows an injection device having an axial dial-down mechanism according to the present invention. Among other components the injection device shown in FIG. 5 comprising a dose setting member 40, an opening 41 defining dial-up and dial-down cam surfaces, a cam follower 42, a torsion spring 43, a ratchet 44, and a piston rod 45. The general idea behind the axial dial-down mechanism is to use the torsion spring 43 to both drive and rotate the piston rod 45 and to ensure that the upper and lower parts of the toothing 48 remain together.
a dial-down cam (16) arranged to receive and engage with a dial-down key (12), wherein the dial-down cam (16) and the dial-down key (12) are adapted to, upon rotation of the dose setting member in a second direction, cooperate to release the torsion spring (18) of the injection device, the second rotation direction being opposite to the first rotation direction.
9. A dial-down mechanism according to claim 1, wherein the dial-up and dial-down cams form part of regions of the same track.
10. A dial-down mechanism according to claim 9, wherein the dial-up and dial-down keys are constituted by the same key, said key being adapted to engage and cooperate with dial-up and dial-down cams of the same track.
11. A medication delivery device comprising a dial-down mechanism according to claim 1.
12. A medication delivery device according to claim 11, wherein the medication delivery device is a handheld medication injection pen.
