Abstract

A counter for a handheld device for dispensing a pharmaceutical substance, has a housing, at least one counter wheel which has readable characters, and a drive part which is designed to rotate the counter wheel, the counter wheel being rotatably attached to a mounting part. The mounting part of the counter is designed independently of the housing, and the drive part is directly attached to the mounting part. The counter can have at least one counter wheel which has readable characters and a drive part which is designed to rotate the counter wheel. The counter wheel has readable characters and is designed in a cylindrical manner and with a central axis, and has a drive part which is designed to rotate the counter wheel, the counter wheel being provided with an engagement toothing via which the drive part acts on the counter wheel so as to rotate same, the drive part having a rotational axis.

Claims

1-10. -10. (canceled)

11. A handheld device (5) for dispensing a pharmaceutical substance with a housing (7) and a counter (1), wherein the counter (1) features at least one counter wheel (2) with readable characters (13) and a drive part (4) designed for rotating the counter wheel (2), wherein the counter wheel (2) is rotatably attached to a mounting part (3), wherein the mounting part (3) is realized independently of the housing (7), and wherein the drive part (4) is directly attached to the mounting part (3), wherein the counter wheel (2) is realized cylindrically and provided with an engagement toothing (18), which is realized on a lower peripheral edge during the intended use and acted upon by the drive part (4) in order to realize the rotation of the counter wheel (2), wherein a remaining outer surface of the counter wheel (2) toward the top can be freely used for applying readable characters, and wherein the mounting part (3) and the drive part (4) are jointly moved relative to the engagement part (21), which practically is stationary with respect to the housing (7) and at best slightly moved in the form of a motion transverse to the deflecting motion during an actuation, in order to carry out a counting process.

13. The handheld device or counter according to claim 11, wherein the rotational axis (D) extends outside the counter wheel (29), namely also with respect to a projection of the counter wheel (2) in the direction of a central axis (A) of the counter wheel (2).

14. The handheld device or counter according to claim 11, wherein the engagement part (21) is attached to the mounting part (3) by means of a return spring (12).

15. The handheld device or counter according to claim 11, wherein a locking part (22) for acting upon the drive part (4) is attached to the mounting part (3).

16. The handheld device or counter according to claim 15, wherein the locking part (22) and the engagement part (21) are arranged such that they are directed oppositely.

17. The handheld device or counter according to claim 11, wherein the rotational axis (D) extends transverse to a central axis (A) of the counter wheel (2).

18. The handheld device or counter according to claim 11, wherein the engagement part (21) acts upon the drive part (4) on the counter wheel side of the rotational axis (D).

19. The handheld device or counter according to claim 11, wherein the locking part (22) acts upon the drive part (4) on the side of the rotational axis (D) of the drive part (4), which faces away from the counter wheel (2).

20. The handheld device or counter according to claim 11, wherein the drive part (4) is realized in the form of a worm shaft with toothing projections that form a circumferential toothing with a helix, which extends obliquely to a rotational axis (D) of the drive part (4) and helically around the rotational axis (D).

12. A counter (1) for a handheld device (5) for dispensing a pharmaceutical substance with at least one counter wheel (2) with readable characters (13) and a drive part (4) with a rotational axis (D) designed for rotating the counter wheel (2), wherein the counter (1) features a return spring (12) for the retrodisplacement after an actuation, wherein the spring (12), which is realized separately of the drive part (4), features an engagement part (21) for interacting with the drive part (4), and wherein the counter wheel (2) is furthermore rotatably attached to the mounting part (3), wherein that the return spring (12), which is arranged underneath the mounting part (3) referred to an actuating direction, is realized in the form of a bow with two end regions that are fastened on the mounting part (3), wherein the end regions transform into the mounting part (3) at different locations on the underside thereof, and in that the mounting part (3) and the drive part (4) can be jointly moved relative to the engagement part (21) in order to carry out a counting process.
