and then supporting the ambulance cot on the platform scale with the second pair of wheels and said kickstand. ## Claims ### Claim 1 A method of weighing a patient on a platform scale, said method comprising: carrying the patient upon an ambulance cot having first and second pairs of wheels and a kickstand having a lowered position and a raised position, wherein said kickstand in the lowered position lifts only the first pair of wheels of the ambulance cot in the air; and supporting the ambulance cot on the platform scale with the second pair of wheels and said kickstand. ### Claim 2 (depends on 1) The method of claim 1 further comprising: supporting the ambulance cot without the patient on the platform scale with the second pair of wheels and the kickstand, and subtracting the weight of the ambulance cot from the combined weight of the ambulance cot and patient to provide the weight of the patient. ### Claim 3 (depends on 1) The method of claim 1 further comprising: releasable mounting the kickstand to an undercarriage of the ambulance cot. ### Claim 4 (depends on 1) The method of claim 1 further comprising: providing the kickstand with a u-shaped support bar. ### Claim 5 (depends on 1) The method of claim 1 further comprising: providing the kickstand with a spring biased support bar. ### Claim 6 (depends on 1) The method of claim 1 further comprising: providing the kickstand with a release, and using the release to enable the kickstand to be moved from at least one of the raised and lowered positions. ### Claim 7 (depends on 1) The method of claim 1 further comprising: providing the kickstand with a release and a support bar spring biased to the raised position, wherein the release is movable from a locked position to a release position; moving the release to release position; and moving the kickstand from the raised position to the lowered position. ### Claim 8 (depends on 1) The method of claim 1 further comprising: providing the kickstand with a release movable from a locked position to a release position, a support bar which may be positioned in the raised position and the lowered position, and a pair of springs acting on the support bar; moving the release to the release position; and moving the support bar from the raised position to the lowered position under the force of at least one of the springs. ### Claim 9 (depends on 1) The method of claim 1 further comprising: providing the kickstand with a release movable from a locked position to a release position, a support bar which may be positioned in the raised position and the lowered position, and a pair of springs acting on the support bar; moving the release to the release position; and moving the support bar from either the raised position or the lowered position under the force of at least one of the springs. ### Claim 10 A method of weighing a patient on a platform scale, said method comprising: carrying the patient upon an ambulance cot having: first and second pairs of wheels, a kickstand movable between a lowered position and a raised position, wherein the kickstand in the lowered position lifts only the first pair of wheels of the ambulance cot in the air, and a release movable from a locked position to a release position, wherein in the release position the kickstand is movable from the raised position to the lower position; positioning the second pair of wheels on the platform scale; moving the release to the release position; moving the kickstand from the raised position to the lowered position to support the ambulance cot on the platform scale with only the second pair of wheels and the kickstand; and subtracting the weight of the ambulance cot from the combined weight of the ambulance cot and patient to provide the weight of the patient.
