Let M be the distance between the intersection points 3a and 3b of the receiver 3 and the stopper 4, shown by the solid line and the two-dot chain line.
This distance M is necessary as the length of the receptor 3, but
If the convex receiver 3 was present near the operator's operation side, it would become an obstacle to the operation, resulting in a problem that the operability would be degraded.

(3)となる。
Since the distance between the center of the hinge 2 and the stopper 4a is C (constant), A 2 +B 2 =C 2 (1) holds (A-R) 2 +B 2 = (C-D) 2 (2) From equations (1) and (2), D(D-2C)=R(R-2A)
(3) becomes.

6が設けてある場合、 F2+(A−L−R)2=(C−D)2 (6)が成り立つ よつてF2=(C−D)2−(A−L−R)2 (7)となる。
When the center of the hinge 2 is at the position 2b and the abutting body 6 is provided, F 2 + (A-L-R) 2 = (C-D) 2 (6) holds, so F 2 = (C-D) 2 -(A-L-R) 2 (7).

次にE>FすなわちE2>F2を証明する。 Next, prove E>F, that is, E 2 >F 2 .

まず、A−L=G (8)とする。 First, let A-L=G (8).

(5)式に(8)式を代入すると、 E2=C2−G2 (9)となる。 Substituting equation (8) into equation (5) yields E 2 =C 2 −G 2 (9).

(7)式に(8)式を代入すると、 F2=(C−D)2−(G−R)2(10)となる。 Substituting equation (8) into equation (7) yields F 2 =(C-D) 2 -(G-R) 2 (10).

(9)、(10)式より、 E2−F2=R(R−2G)−D(D−2C) (11)の関係が得られる。 From equations (9) and (10), the relationship E2 - F2 =R(R-2G)-D(D-2C) (11) is obtained.

(11)式に(3)式を代入すると、 E2−F2=2R(A−G) (12)となる。 Substituting equation (3) into equation (11) yields E 2 −F 2 =2R(AG) (12).
