More particularly, the cam face 15 of first cam 13 and the cam face 44 of second cam 43 have the guide surface 15a and the 44a that open wide that forms along hand of spiral inclination certain angle, thereby when lid 3 is opened above predetermined angular, be connected to first hinge axis 10 of lid 3 owing to promote the elastic force of first elastic component 50 of moving link 40 and can open the direction rotation along lid.When lid 3 is opened beyond predetermined angular, be applied to first hinge axis 10 along the revolving force of the lid of opening direction, therefore, lid 3 stays open.
In addition, the cam face 15 of first cam 13 and the cam face 44 of second cam 43 comprise the guide surface 15b and the 44b of the closure that becomes along the direction of rotation of first hinge axis 10, thereby when the angle of in the process of close cap 3, opening during less than predetermined angular, by the gravity of lid 3, first hinge cam 10 that is connected with lid is along the direction rotation of cover closing.When the guide surface 44b of the closure of the guide surface 15b of the closure of first cam 13 and second cam 43 contacted with each other, the elastic force of first elastic component 50 did not influence the rotation of first hinge axis 10, and therefore, lid 3 is closed owing to himself gravity.
On the other hand, cam face 15 and 44 can not comprise closed guide surface 15b and 44b, therefore, the guide surface 15a that opens wide at the end of the guide surface 15b of closure and the guide surface 44a that opens wide under the state that the end of the guide surface 44b of closure supports mutually, lid 3 is closed owing to himself gravity.
For the smooth sliding between the cam face 44 of the cam face 15 that is implemented in first cam 13 and second cam 43, the sliding agent of for example grease is coated on the cam face 44 of the cam face 15 of first cam 13 and second cam 43.Arranged outside at second cam 43 has columniform leakage prevention member 70, is used to prevent to be coated in sliding agent on each cam face 15 and 44 from cam 13 and 43 let out (seeing that Fig. 3 is to Fig. 5).
In Fig. 5, second hinge axis 20 comprises supporting projections 22 at Fig. 3, and this supporting projections 22 is formed on an end relative with the lid coupling part 21 of the second holding portion 31b that extends into shell 30.The shaft insertion hole 34a of supporting projections 22 covered things 34 blocks, thereby described supporting projections 22 is supported in the inside of overcover 34.The vibration absorption unit that is arranged among the second holding portion 31b of shell 30 comprises: fixed component 80 is configured to be supported by the supporting member 60 of cam driver element; Guide peg 90, the one end inserts the center of fixed component 80, and its other end rotatably inserts the center of second hinge axis 20, is used for the fixed component 80 and second hinge axis 20 are coupled together; Second elastic component 100 is wrapped on the guide peg 90, and an end of described second elastic component 100 is fixed to fixed component 80 and the other end is fixed to second hinge axis 20.
Be formed with first respectively at the center of the fixed component 80 and second hinge axis 20 and insert the groove 81 and the second insertion groove 22a, the opposite end of described guide peg 90 is inserted first and is inserted among the groove 81 and the second insertion groove 22a.
Second elastic component 100 is torque springs.But the present invention is not limited to this, can change where necessary.
Inside at the housing 32 of shell 30, be formed with rotation in a side of fixed component and prevent projection 31b-1 (shown in Figure 3), this rotation prevents the longitudinal extension predetermined length of projection 31b-1 along shell 30, thereby prevents that fixed component 80 from rotating in the second holding portion 31b.Fixed component 80 comprises that rotation prevents groove 82, and rotation prevents that projection 31b-1 is engaged with this rotation and prevents in the groove 82.
When lid 3 when the state of opening hingedly rotates to closing state, the feasible rotational resistance that is produced by the torsional stress of second elastic component 100 of vibration absorption unit is passed to lid 3 by second hinge axis 20, thereby slow down the rotary speed of lid 3, therefore, lid 3 is closed reposefully.
On the other hand, when lid 3 when closing state hingedly rotates to the state of opening, vibration absorption unit makes second hinge axis 20 open the direction rotation along lid by making second elastic component 100 from the restoring force that twisting states is returned to second elastic component 100 of original state, thereby the tensile force of lid 3 increases.
More particularly, second elastic component 100 comprises member body 101 on the guide peg 90 and first standing part 102 and second standing part 103 that is formed on the opposite end of described member body 101.In first fixed groove 83 that first standing part 102 center with fixed component 80 that is fixed on is adjacent to form, among the second fixed groove 22b that second standing part 103 center with second hinge axis 20 that is fixed on is adjacent to form.When lid 3 was opened, second elastic component 100 did not reverse.On the other hand, when lid 3 was closed, second elastic component 100 was reversed.
As a result, when the lid of opening when the cover closing direction is rotated, 20 rotations of second hinge axis, therefore, second standing part 103 of second elastic component 100 is with 20 rotations of second hinge axis.When the rotation of second hinge axis 20, second elastic component 100 is reversed and first standing part 102 that is fixed to second elastic component 100 on the fixed component 80 is maintained fixed.The torsional stress of second elastic component 100 increases the rotational resistance of lid 3, and therefore, lid 3 is closed reposefully.
On the other hand, when the lid of closing is opened direction when rotation along lid, second hinge axis 20 is opened the direction rotation by the restoring force of second elastic component 100 that reverses along lid, therefore, even by less external force also uncap easily.
Hinge means 5 is installed is made that lid 3 more stably is connected with casing 2 under lid 3 pent states, thereby lid 3 is supported at the top of casing 2.Therefore, under the state that rotates in the opposite direction with the lid side of opening, hinge means 5 is installed at second hinge axis 20 to reverse second elastic component 100.At this moment, in the process of coupling part 3a by being connected to lid 3 in lid coupling part 21 with second hinge axis 20, the restoring force of second elastic component 100 that reverses, second hinge axis 20 rotates in the opposite direction according to the answer side with second elastic component 100.As a result, be difficult to the lid coupling part 21 of second hinge axis 20 is connected on the coupling part 3a of lid 3.
In order to address this problem, as shown in Figure 9, the connecting hole 34b and the shaft insertion hole 34a of the overcover 34 of an end that is attached to shell 30 regularly are adjacent to form, thereby the anti-shotpin 110 of rotation is inserted in the shell 30 by described connecting hole 34b.The supporting projections 22 of second hinge axis 20 is formed with stop portions 22c, and the anti-shotpin 110 of rotation that this stop portions 22c is inserted into by connecting hole 34b in the shell 30 blocks, thereby has prevented the rotation of second hinge axis 20.
When second hinge axis 20 when the rotation of direction makes that second elastic component 100 reverses, the anti-shotpin 110 of rotation is inserted in the shell 30 by connecting hole 34b, blocks thereby stop portions 22c is inserted into an end of the anti-shotpin 110 of rotation in the shell 30.As a result, along the answer direction rotation of second elastic component 100, therefore, second elastic component 100 does not keep reversing second hinge axis 20.
