(the main action of locking device)
Below, be transformed into close the door state from door opening state (door is opened) with reference to Fig. 6 (a)～Fig. 8 (b) when using above locking device RE, perhaps the action when the state of closing the door is transformed into door opening state once more describes.In these figure; Arrow is to the right represented to opening the afterburning active force of direction opposite house; Arrow left (1) and (2) expression overcomes active force and pushing force that opposite house pushes; Arrow (1) expression is from opening the pushing force to the closing direction opposite house, and arrow (2) expression from the state of closing the door further to the pushing force of closing direction.
(1) at first; Under door opening state; As inferring, utilize the active force of the energizing spring 69 of hinge side that door 9A, 9B opposed end is each other rotated into ヘ font (if active force then further is more by force the V font) to the front direction according to Fig. 1 (a), Fig. 1 (b).In addition, under this state, through with hand to direction of arrow thrust door 9B, then door 9A, 9B is folded each other, and can strengthen the width of main body 8 side opening portions.Under this door opening state; Locking device RE is shown in the right side of Fig. 6 (a); It is off-position that converting member 3 is in not the common state of erecting that ram 2 is applied load, and ram 2 overcomes the active force of boosting mechanism S1 and moves down, and utilizes chain shot 4 to remain the state that this has moved.This chain shot 4 becomes the fastening mode shown in Fig. 6 (b), a pair of fastening portion 42 constraints that promptly constitute chain shot 4 down claw 24a and the fastening of holding sections 24 in framework 40.
(2) making a 9A, 9B from opening the occasion that becomes the state of closing the door, shown in Fig. 6 (a), with the finger overcome hinge 7 energizing spring 69 active force and to the closing direction thrust door 9B shown in the arrow (1) or the door 9A.In this pushing process, converting member 3 shown in the left side of Fig. 6 (a), when the 8e butt of the location division of impact portions 33 and main body side peristome, with its reaction force overcome spring mechanism S2 active force and around turning clockwise.So ram 2 is pushed downwards by the pushing portion 32 of converting member, and utilize this pushing force to overcome the active force of boosting mechanism S1 and move down.So; If from the direction of arrow pushing ram 2 of above-mentioned fastening mode to Fig. 6 (b); Then above-mentioned fastening is disengaged, and chain shot 4 links with the release of the pushing force of opposite house, and slide mass 41 is by not shown active force pushing and make fastening portion 42 to sliding from framework 40 outstanding directions; Final shown in Fig. 7 (b), remove the constraint of 42 couples of claw 42a of fastening portion and converted non-fastening mode to.
Fig. 7 (a)～Fig. 8 (b) expression has been removed the fastening that device 2 is hit in head-on collision from chain shot 4, engages with the carrier 8c of main body side peristome and remains the details of the state of closing the door up to ram 2.In above locking device RE, when discharging the pushing force of opposite house, door 9B moves to opening direction with regard to the active force that utilizes energizing spring 69.At this moment, converting member 3 utilizes the active force of spring mechanism S2 to rotate from the operating position to erecting direction, and shown in Fig. 8 (a), Fig. 8 (b), is transformed into common off-position.In the process of off-position conversion, ram 2 utilizes the active force of boosting mechanism S1 and moves to the direction of giving prominence to from housing 1 shown in Fig. 7 (a), just the soffit butt of concavity of the upper end of last holding section 21 and formation carrier 8c at converting member 3.Door 9B utilizes the frictional force that receives because of this butt that speed is reduced, and moves to opening direction lentamente.Then; Ram 2 utilize boosting mechanism S1 active force and to the top by reinforcing; But at this moment if shown in Fig. 8 (a), reach the concavity that falls that forms carrier 8c; Then ram 2 from fall concavity the lower surface with fall the inner edge portion pressure of concavity and contact, as Fig. 8 (b) shown in, utilize active force mobile a little and engage simultaneously with the recess of concavity to opening direction with door 9B, door 9B maintenance (locking) is the state of closing the door.When ram 2 is relative with carrier 8c; Though such action is protruding in falling in the concavity and producing when engaging with it and the attack sound that is in proportion of active force (action sound or impulsive sound when engaging are identical) of this carrier; But because the front end that makes ram contacts with the inner edge portion pressure of concavity from the lower surface of concavity of falling of carrier; Engage simultaneously, thereby need not increase brake component and just can reduce this attack sound with simple structure.
(3) in the occasion that makes door 9 be in door opening state once more, under the state of closing the door of Fig. 8 (b), with hand or finger overcome hinge side energizing spring 69 active force and to the closing direction thrust door 9B of arrow (2) or door 9A up to the whole stroke of covering as Fig. 6 (a) shown in.In other words, the state of the arrow (2) of Fig. 8 (b) expression when the closing direction thrust door, the state when arrow (2) expression of Fig. 6 (a) discharges this pushing force.At this, if to the arrow (2) of Fig. 8 (b) to closing direction thrust door 9B, then the ram 2 of locking device RE overcomes the active force of boosting mechanism S1 and moves downwards.In this process; Converting member 3 is all kept the off-position that the active force with spring mechanism S2 erects before contact with location division 8e, and the active force that overcomes spring mechanism S2 with utilizing its reaction force after location division 8e contacts in impact portions 33 is around turning clockwise.
So; Ram 2 is pushed downwards by the pushing portion 32 of converting member 3; And shown in Fig. 6 (b), overcome the active force of boosting mechanism S1 and move down with this pushing force, finally descend the claw 24a of holding section 24 to receive to constitute chain shot 4 a pair of fastening portion 42 constraint and be drawn into and fastening in framework 40.That is to say that chain shot 4 converts the fastening mode into from non-fastening mode.And if pushing force is released, then door utilizes the active force of energizing spring 69 and shown in the right figure of Fig. 6 (a), moves to opening direction, and in this process, converting member 3 also utilizes the active force of spring mechanism S2 to the off-position conversion that erects.Afterwards, opposite house 9A, 9B to the engaging that each racking of closing direction all repeats a 9A, 9B keep, and engagement release.
