On the other hand, when the second housing 3 is opened into 180 degree by 90 degree relative to the first housing 2 and is opened into by 270 degree At 360 degree, although the rotation of the 2nd B locking cams component 25 can be allowed, the jut 29d and 29d of the second arresting lever 29 Will be fallen into when opening angle is 180 degree among ditch portion f and h, and fall into when opening angle is 360 degree ditch portion g and e it In.In addition, during closure then in contrast.

Though in above-mentioned any situation, when the first arresting lever 28 and the second arresting lever 29 jut 28d, 28d with 29d, 29d are adjoint among each ditch portion a~d and e~h of the 2nd A locking cams component 24 and the 2nd B locking cams component 25 The 2nd A locking cams component 24 and the 2nd B locking cams component 25 rotation and on move to its respective side face 24a with During 25a, it will jut 28d, 28d and 29d, the 29d of generation moment of friction, the first arresting lever 28 and the second arresting lever 29 pass through This frictional force and each hooking sheet 26d and 26d for pushing mobile retainer 26, and make it rotate.

In this regard, when the first housing 2 and the second housing 3 open operation, and the 2nd A locking cams component 24 is towards up time When the rotation in pin direction and the 2nd B locking cams 25 rotation counterclockwise of component are all restricted, mobile retainer The holding section 26c4 of 26 snap-latch piece 26c and 26c the first holding section 26c1~the 4th will be fastened on the confined locking of rotation Portion (element numbers are treated aftermentioned).In addition, during closure then in contrast.

If in addition, the switching action of the first housing 2 and the second housing 3 is further described, first, when the first housing 2 And second housing 3 when being closed as closure state as shown in Figure 1, shown in such as Figure 18 (a), first choice rotates limitation hand First nose of cam 36a of the locked component 36 of section 22 is connected to the outer peripheral face of the first A locking cams component 34, and the second cam Convex portion 36b is fastened on the first B cam recesses 35b of the first B locking cams component 35.Accordingly, because under this closure state, energy What is rotated is only assembled with the first axle bar 10 of the first A locking cams component 34, and second hinge bar 12 can not simultaneously be rotated, Therefore the first housing 2 will toward the clockwise direction be rotated and opened relative to the second housing 3 jointly with first axle bar 10.In this shape Under state, as described above, the second selectivity rotates the snap-latch piece 26c and 26c of the mobile retainer 26 of limiting means 23 the first card Although conjunction portion 26c1 is fastened on the fastener i positioned at the side of the 2nd A locking cams component 24, but by the engagement direction shown in figure It will be evident that this engaging and A locking cams 24 rotation toward the clockwise direction of component of non-limiting the 2nd, but allow second 24 rotation toward the clockwise direction of component of A locking cams, therefore therefore the rotation of first axle bar 10 can't produce obstacle.Separately On the one hand, the snap-latch piece 26c of mobile retainer 26 the 4th holding section 26c4 is fastened on positioned at one of second hinge bar 12 The fastener n of 2nd B locking cams component 25 of side, and be to be fastened on the 2nd B locking cams component 25 of limitation towards side counterclockwise To rotation side, therefore, the operation of limiting means 23 is rotated by the second selectivity, second hinge bar 12 is towards side counterclockwise To rotation will be restricted, and second hinge bar 12 by 0 degree be opened into 90 degree in the case of can't rotate.

Thus, first axle bar 10 is rotated toward the clockwise direction, the first housing 2 is opened relative to the second housing 3 Way in state be plotted among Figure 19.As seen from Figure 19, when the first housing 2 is cut with scissors relative to the second housing 3 with first When chain bar 10 is opened for fulcrum, the second selectivity rotates the mobile retainer 26 of limiting means 23 by the first arresting lever 28 Push and counterclockwise rotate with the push-pads 28c and 29c of the second arresting lever 29.

Then, the first housing 2 has been plotted among Figure 20 relative to the state that the second housing 3 is opened into 90 degree.By Figure 20 It can be seen that, in this case, first choice rotates the first nose of cam 36a and first of the locked component 36 of limiting means 22 2nd A cam recesses 34c of A locking cams component 34 is relative, and the second nose of cam 36b and the first B locking cams component 35 The first B cam recesses 35b it is relative.

From the above, although the first housing 2 can continue to open at first blush, but as noted previously, as the second selectivity turns The mobile retainer 26 of dynamic limiting means 23 is counterclockwise rotated, and as shown in Figure 20 (c), its snap-latch piece 26c and 26c The first holding section 26c1 and the 3rd holding section 26c3 will be fastened on fastener k and o, and limit first axle bar 10 further Rotation, therefore, when opening angle reaches 90 degree, the first housing 2 will be unable to be further continued for rotate.In this regard, with regard to the second housing 3 For aspect, the second selectivity rotates the snap-latch piece 26c and 26c of the mobile retainer 26 of limiting means 23 the first holding section Although 26c1 and the 3rd holding section 26c3 are fastened on the fastener o of the first B locking cams component 35, but the first B locking cam groups The rotation of part 35 counterclockwise is not to be restricted, therefore rotation of the second hinge bar 12 after 90 degree is to be allowed 's.Therefore, when the first housing 2 is opened into after 90 degree relative to the second housing 3, the second housing 3 can be held relative to the first housing 2 It is continuous to open.It must supplement herein, when the first housing 2 is opened into 90 degree relative to the second housing 3, the first housing 2 still can court Closing direction is rotated, therefore, and the first housing 2 still can carry out closed procedure relative to the second housing 3.

Then, the second housing 3 has been plotted in figure relative to the first housing 2 by 90 degree of states being opened into the way of 180 degree Among 21.As seen from Figure 21, retainer 26 is moved by the operation of the first arresting lever 28 and the second arresting lever 29 towards up time Pin direction is rotated.

Second housing 3 has been plotted among Figure 22 relative to the state that the first housing 2 is opened into 180 degree.According to Figure 22 institutes Show, first choice rotates the first nose of cam 36a, the second nose of cam 36b difference of the locked component 36 of limiting means 22 The 2nd B cam recesses 35c of the 2nd A cam recesses 34c, the first B locking cams component 35 with the first A locking cams component 34 Relatively, both sides can be rotated at first blush for first axle bar 10 and second hinge bar 12.But in fact, such as Figure 22 (c) Shown, now the mobile retainer 26 of the second selectivity rotation limiting means 23 passes through the first arresting lever 28 and the second arresting lever 29 Operation and rotated toward the clockwise direction, and its snap-latch piece 26c and 26c the first holding section 26c1 and the 4th holding section 26c4 is fastened on the fastener j and q of the 2nd A locking cams component 24 and the 2nd B locking cams component 25, therefore, by its engaging Direction can be seen that the rotation of the second housing 3 counterclockwise is limited.Thus, the first housing 2 can be relative to second Housing 3 carries out clockwise rotate toward 270 degree of direction.

Then, the first housing 2 has been plotted in figure relative to the state that the second housing 3 is opened into 270 degree of way by 180 degree Among 23.As seen from Figure 23, the mobile retainer 26 of the second selectivity rotation limiting means 23 passes through the first arresting lever herein 28 and second arresting lever 29 operation and counterclockwise rotated.
