Next, an effect on the wrist of the carrier by tilting the handle will be described below.
FIG. 9 is an explanatory diagram showing a wrist state when the handle is not tilted as a comparative example, and FIG. 10 is an explanatory diagram showing a wrist state when the handle is tilted according to the present embodiment. In the following description, the case of the intermediate handle 20C will be described.
9 and 10 show a conveyance state in which the head side of the conveyed person is raised, and the angle of the upper body side sheet 10 with respect to the horizontal plane is θ. In the actual field, the transported person often has a posture in which the trunk is bent as shown in the figure due to the sitting posture or the lowering of the buttocks, so the model assumes that the inclination angle of the upper limb (hereinafter referred to as the upper limb inclination angle) is θ. Are being considered.
As shown in FIG. 9, since the intermediate handle 20C has the upper limb inclination angle θ, the carrier has a force to bend the intermediate handle 20C by the upper limb inclination angle θ in order to level the intermediate handle 20C. Necessary.
In contrast, as shown in FIG. 10, by leaving is inclined by pre handle angle theta _G intermediate portion Possession 20C with respect to the longitudinal center line Y, the transport user an intermediate portion Possession 20C horizontal Therefore, the intermediate handle 20C may be bent by an angle (θ−θ _G ).

FIG. 11 shows the force applied to the handle when the upper limb inclination angle θ is assumed.
As shown in FIG. 11, F ₁ is used for the end handle 20AT where the head is located, F ₂ is used for the intermediate handle 20CT where the flank is located, and the intermediate handle 20CU where the thigh is located. the force of F ₃ is applied.

FIG. 12 shows the holding force against F ₂ applied to the intermediate handle 20CT where the flank is located. To transport while maintaining the posture shown in FIG. 11, the transport person holding force equivalent to F ₂ F _{2 '(hereinafter,} necessary holding power) is required to exhibit. The necessary holding force F ₂ ′ includes a force F _A required for the intermediate handle 20CT in the vertical direction (hereinafter referred to as a required vertical holding force) and a holding force F _B required for the intermediate handle 20CT in the horizontal direction ( Hereinafter, it is divided into necessary horizontal holding force).
When F _B is expressed using F ₂ and θ, it is expressed as in Equation 1.
F _B = F ₂ × sin θ ...... Equation 1
It requires leveling force F _B is the force in the direction of sliding the hand, and because there also force (moment) that causes rotation in the direction of twist of the wrist, if increased, the burden on the wrist.

FIG. 13 is an explanatory diagram showing the force applied to the wrist.
If the virtual rotation center of the wrist is P and the distance from the virtual rotation center P to the grip position is L, a moment of F _B × L is applied to the wrist.

Figure 14 shows a holding force against F ₂ applied to the intermediate portion Handle 20CT when is tilted intermediate portion Possession 20CT only pre handle angle theta _G relative to the longitudinal center line Y.
The required holding force F ₂ ′ is divided into a required vertical holding force f _A and a required horizontal holding force f _B.
When the required horizontal holding force f _B is expressed by using F ₂ , θ, and θ _G , it is expressed as in Expression 2.
f _B = F ₂ × sin (θ−θ _G ) Equation 2
When the handle angle θ _{G is set} to 10 °, the relational expression between F _B and f _B is expressed by the following relation from Expressions 1 and 2.
In the range of 5 ° <θ <95 °,
F ₂ × sin θ> F ₂ × sin (θ−10 °)
F _B > f _B ... Formula 3
Therefore, when the upper limb inclination angle θ is in the range of 5 ° to 95 °, the required horizontal holding force f _B of this embodiment is smaller than the required horizontal holding force F _{B of the} comparative example.

If, upper limb inclination angle θ is 30 °, the force F ₂ applied to the intermediate portion possession 20CT is assumed to be 15 kg, holding force required in the horizontal direction in the intermediate portion Handle 20CT of the comparative example with the present embodiment,
F _B = F ₂ × sin θ = 15 × sin (30 °) = 7.5 kg
F _B = F ₂ × sin (θ−θ _G ) = 15 × sin (30 ° −10 °) = 5.1 kg
Therefore, when the upper limb inclination angle is 30 °, as compared with this embodiment, should the horizontal holding force F _B of the Comparative Example is reduced 32%.

Similarly, FIG. 15 shows the required horizontal holding force when the upper limb inclination angle θ is changed from 0 ° to 45 °.
As shown in FIG. 15, when the upper limb inclination angle θ is less than 5 °, the required horizontal holding force f _{B of} this embodiment increases, but when it exceeds 5 °, the required horizontal holding force f _B decreases.
In addition, although it verified about intermediate part handle 20CT, the same relationship holds also when hold | maintaining a to-be-transported person's thigh and lower leg part.
