Abstract

A grating device, a method of operating a grating device, and a device are disclosed. A grating device includes a band being flexible to vary a separation distance between first and second ends of the band, first and second fingerholds respectively located at the first and second ends and configured to receive respective first and second fingers of a user, and a first grating element located on the first side and at the first end. The first and second fingerholds are configured to hold the fingers on the second side of the band such that (i) the separation distance between the first and second ends of the band decreases when the fingers of the user are moved closer to one another, and (ii) the separation distance between the first and second ends of the band increases when the fingers of the user are moved apart from one another.

Dependent claims

A grating device comprising:

a band extending in a longitudinal direction from a first end to a second end, the band possessing a first side and a second side opposing the first side, the first and second sides extending in the longitudinal direction, the band being flexible to vary a separation distance between the first end and the second end;
a first fingerhold located at the first end and configured to receive a first finger of a user;
a second fingerhold located at the second end and configured to receive a second finger of the user;
and
a first grating element located on the first side and at the first end of the band,
the first and second fingerholds being configured to hold the first and second fingers of the user on the second side of the band such that:
(i) the separation distance between the first and second ends of the band decreases when the first and second fingers of the user are moved closer to one another, and (ii) the separation distance between the first and second ends of the band increases when the first and second fingers of the user are moved apart from one another.
