Abstract
A linear measurement device for measuring a wheelchair user for fitting a wheelchair, with a measuring bar having with a scale and a fixed locater attached at a first end. A second locator opposing the first locater moves on the measuring bar to a selected position for determining a distance measurement relative to the fixed locator for fitting the wheelchair user to the wheelchair. A method of measuring for wheelchair fitting with a linear measurement apparatus is disclosed.
Claims11
A linear measurement device for obtaining measurements for fitting a wheelchair user to a wheelchair, comprising:
- a measuring bar provided with a scale having a plurality of spaced-apart demarcations and associated numerical indicia;
- a fixed locater attached at a first end of the measuring bar;
- a second locator attached to a slider carried on the measuring bar, the second locater opposing the fixed locater and having an indicator thereon that aligns with a portion of the scale;
- a pair of pressure pads, each received on a respective one of the fixed and second locators, for contacting a selected body surface for determining a distance measurement, the pressure pad selectively attached to the second locater to position facing towards or away from the opposing pad on the fixed locator,
- whereby the second locator moves relative to a longitudinal axis of the measuring bar to a selected position for determining a distance measurement relative to the fixed locator for fitting the wheelchair user to the wheelchair.
A method of measuring for fitting a wheelchair user to a wheelchair, comprising the steps of:
- (a) providing a measuring bar having a scale having a plurality of space-apart demarcations and associated numerical indicia;
- (b) positioning a fixed locater attached at a first end of the measuring bar and having a pressure plate facing in a first direction against a first surface relative to a wheelchair user and from which a measurement is to be determined;
- (c) moving a second locator having a measuring index longitudinally on the measuring bar to a second surface relative to the wheelchair user and from which a measurement between the first surface and the second surface is to be determined, the second locator having a pressure plate selectively attached (i) to face in a second direction opposing the first direction and towards the pressure plate on the fixed locator for an outside measurement or (ii) to face in the first direction away from pressure plate on the fixed locator for an outside measurement;
- (d) determining the distance measurement between the first surface and the second surface indicated by the scale relative to a measuring index,
- whereby the second locator being moved relative to a longitudinal axis of the measuring bar to the second surface determines a distance measurement relative to the fixed locator for fitting the wheelchair user to the wheelchair.
