The specific embodiment
Below, explain enforcement most preferred embodiment of the present invention with reference to accompanying drawing.
Fig. 1～Fig. 6 represents the first embodiment of the present invention.The hinge means A of present embodiment has first hinge member, 1, the second hinge member (hinge member) 2, hinge axis 3, movable member 4 and helical spring (force application mechanism) 5.
First hinge member 1 has a portion 11 and with the bottom 12 of the base end part (right part in Fig. 2) of this one 11 sealing, is installed to for example sending in the words portion of pocket telephone un-rotatably.In the tube portion 11 of first hinge member 1, form a pair of limiting groove 13 that extends to base end side from its front end face.This a pair of limiting groove 13 is circumferentially leaving 180 ° of ground configurations.On the central portion of bottom 12, form and make the axis through hole consistent 14 with the axis of tube portion 11.
Above-mentioned movable member 4 has plectane portion 41.This plectane portion 41 is entrenched on the leading section inner peripheral surface of a portion 11 slidably.On the outer peripheral face of plectane portion 41, form a pair of protuberance 42.This a pair of protuberance 42 is circumferentially leaving 180 ° of ground configurations.A pair of protuberance 42 respectively at length direction slidably and circumferentially being inserted into un-rotatably in a pair of limiting groove 13 in tube portion 41.Thus, movable member 4 does not turn on first hinge member 1 and is connecting movably at its axis direction.
Hinge axis 3 is inserted in the through hole 14 of first hinge member 1 rotationally.The pars intermedia of this hinge axis 3, rotatable and be inserted in slidably in the through hole 43 that the central portion of the plectane portion 41 of movable member 4 forms.Thus, hinge axis 3 makes under its axis state consistent with the axis of first hinge member 1, is being rotatably supported on first hinge member 1.Base end part at hinge axis 3 forms head 31.By the butt of this head 31, stoped hinge axis 3 to move towards the front direction from the base end side of first hinge member 1 with bottom 12 outside end faces.The leading section of hinge axis 3 is outstanding to the outside from the front end opening of first hinge member 1.
From the leading section of the outstanding hinge axis 3 of the leading section of first hinge member 1, second hinge member 2 is installed.Second hinge member 2 has on the axis direction of hinge axis 3, forms, is configured in across contact site 2B the installation portion 2A of a side opposite with movable member 4 with movable member 4 opposed contact site 2B with this contact site 2B split.Each central portion at contact site 2B and installation portion 2A forms through hole 21,22.The leading section of hinge axis 3 is embedded in each through hole 21,22.Hinge axis 3 is chimeric at least to be fixed in the through hole 22 of installation portion 2A.Therefore, installation portion 2A is connected with first hinge member 1 rotationally by hinge axis 3.Contact site 2B can not be connected rotationally with installation portion 2A.And contact site 2B is pushed on the installation portion 2A by helical spring 5, can not move to the axis direction of hinge axis 4 in fact with respect to installation portion 2A.Herein, contact site 2B also can form as one with installation portion 2A.
Between the bottom 12 of first hinge member 1 and movable member 4, be provided with helical spring 5.5 pairs of movable members 4 of helical spring carry out the application of force towards the front end of first hinge member 1, so that its contact site 2A with second hinge member 2 contacts.As a result, the installation portion 2B of second hinge member 2 and contact site 2A and movable member 1 are assembled on first hinge member 1 integratedly by hinge axis 3, and constituting integral body is Componentized hinge means A.
The opposed faces 44 with respect to second hinge member 2 (contact site 2B) of movable member 4, for the perpendicular plane of the axis of hinge axis 3.As Fig. 2～shown in Figure 4, on opposed faces 44, be provided with spheroid (first engagement lugs) 6 and protuberance (second engagement lugs) 45.Spheroid 6 and protuberance 45 pass through the elastic force of movable member 4 to the helical spring 5 of second hinge member, the 2 side application of forces, with opposed faces 23 contacts with respect to movable member 4 of contact site 2B.Spheroid 6 and protuberance 45 are circumferentially to leave 180 ° of ground configurations on the circumference at center at the axis with hinge axis 3.Spheroid 6 is buried underground under the state that its part is given prominence to from opposed faces 44 and is fixed on the movable member 4.Spheroid 6 also is embedded on the movable member 4 rotationally.On the other hand, protuberance 45 is to the radially extension of movable member 4, and the cross section forms circular-arc.The cross sectional shape of protuberance 45 also can be other shape, for example trapezoidal shape.The length setting of protuberance 45 becomes the outer path length than spheroid 6.And protuberance 45 is configured on the circumference identical with spheroid 6.Just, so that the circumference that the central authorities of protuberance 45 length directions are positioned at configuration spheroid 6 is that mode on the same circumference disposes protuberance 45.At this, because of the length of protuberance 45 outer path length than spheroid 6, among Fig. 4 shown in imaginary line, the medial end of the protuberance 45 that the footpath of movable member 4 makes progress, in the position of the inboard that radially is positioned at spheroid 6 of movable member 4, the outboard end of protuberance 45 is positioned at the position in the outside of spheroid 6.And, the inboard of protuberance 45 and outboard end be identical apart from spheroid 6 to radially outstanding length.In other words, by with the inboard of protuberance 45 and outboard end be identical length apart from spheroid 6 to radially outstanding length, protuberance 45 is located on the circumference of configuration spheroid 6.
The opposed faces 23 with respect to movable member 4 of contact site 2B becomes and the perpendicular plane of the axis of hinge axis 3.As Fig. 2 and shown in Figure 5, on opposed faces 23, form a pair of first coupling recess 24A, 24B, a pair of second coupling recess 25A, 25B and guide channel 26.
The first coupling recess 24A, 24B are the positions that engages with spheroid 6, and the bottom surface of the first coupling recess 24A, 24B is that the concave spherical surface of same curvature radius constitutes by having outer peripheral face with spheroid 6.The axis that a pair of first coupling recess 24A, 24B are configured in hinge axis 3 is on the circumference at center.The circle diameter that disposes the first coupling recess 24A, 24B is identical with the circle diameter of configuration protuberance 45 and spheroid 6.The first coupling recess 24A, 24B dispose along circumferentially leaving than 180 ° of bigger predetermined angulars.In the present embodiment, leave 270 ° of ground configurations.At this, spheroid 6 becomes the member that engages with a side the first coupling recess 24A, if the turned position of relative first hinge member 1 with second hinge member 2 of this moment is a primary importance, when second hinge member, 2 relative first hinge members 1, when a direction (being clockwise direction among Fig. 5) was rotated 270 °, spheroid 6 engaged with the opposing party's the first coupling recess 24B from primary importance.Below, the turned position of relative first hinge member 1 of second hinge member 2 of this moment is called the second place.
The second coupling recess 25A, 25B are the positions that engages with protuberance 45.At this, radially the second coupling recess 25A of contact site 2B, the length of 25B are set the length roughly the same with protuberance 45 for.And the bottom surface of the second coupling recess 25A, 25B is made of the arc surface that has with constituting the arc surface same curvature radius of protuberance 45 outsides.The a pair of second coupling recess 25A, 25B is configured in the first coupling recess 24A, 24B the configuration the same circumference of circumference on.Just, the central configuration of the length direction of the second coupling recess 25A, 25B be positioned at the first coupling recess 24A, 24B the configuration circumference be on the same circumference.The second coupling recess 25A, 25B are to dispose along circumferentially leaving formula with the identical angle of angle of leaving of the first coupling recess 24A, 24B.And the relative first coupling recess 24A of the second coupling recess 25A, 25B, 24B are respectively along circumferentially leaving 180 ° of ground configurations.Therefore, when second hinge member 2 turns to primary importance, as shown in Figure 6, when spheroid 6 engages with a side the first coupling recess 24A, protuberance 45 engages with a side the second coupling recess 25A, and when second hinge member 2 turned to the second place, spheroid 6 engaged with the opposing party's the first coupling recess 24B, simultaneously, protuberance 45 engages with the opposing party's the second coupling recess 25B.
Because the first coupling recess 24A, 24B and the second coupling recess 25A, 25B are as above-mentioned configuration, when second hinge member 2 rotates between the primary importance and the second place, at assigned position, the spheroid 6 and the second coupling recess 25A, opposed while of 25B, protuberance 45 is mutually opposed with the first coupling recess 24A, 24B.At this moment, because the length of protuberance 45 is longer than the diameter of the first coupling recess 24A, 24B, protuberance 45 can not engage with the first coupling recess 24A, 24B, but crosses over these members and pass through.That is to say that the first junction surface 24A, 24B are crossed in the radially inner side that is positioned at the first coupling recess 24A, 24B of protuberance 45 and the both ends in the outside, and on the opposed faces 23 that is positioned at its inboard and the outside, slide.Therefore, when protuberance 45 rotates between the primary importance and the second place at second hinge member 2, can not have any problem ground and on opposed faces 23, slide swimmingly.,, therefore, were it not for when forming guide channel 26 described below, then can engage with the second coupling recess 25A, 25B because spheroid 6 is roughly a contact with respect to opposed faces 23.
In order to eliminate this condition of poor, in this hinge means A, on opposed faces 23, form guide channel 26.This guide channel 26 extends to the opposing party's the first coupling recess 24B from a side the first coupling recess 24A on the circumference of the configuration first coupling recess 24A, 24B.Therefore, when second hinge member 2 rotated between the primary importance and the second place, spheroid 6 moved in guide channel 26.And guide channel 26 cross sections are circular-arc, and the radius of curvature of its bottom surface is identical or big slightly with the radius of spheroid 6.Therefore, spheroid 6 is at the central portion on the width of guide channel 26 bottom surfaces, just the bottom central part that disposes is rotated or slided on the circumference of the configuration first coupling recess 24A, 24B.The depth ratio first coupling recess 24A of guide channel 26, the depth as shallow of 24B, this is in order to prevent that guide channel 26 from hindering the spheroid 6 and the first coupling recess 24A, the joint of 24B.Corresponding to the depth ratio first coupling recess 24A of guide channel 26, the degree of depth of 24B is more shallow, the width of guide channel 26 (radial width of second mating part 2) is also narrow than the width (diameter) of the first coupling recess 24A, 24B.
In the hinge means of said structure, when second hinge member 2 rotates between the primary importance and the second place, because spheroid 6 does not engage with the second coupling recess 25A, 25B, protuberance 45 does not engage with the first coupling recess 24A, 24B yet, and second hinge member 2 is rotated swimmingly.In addition, though be configured in the first coupling recess 24A respectively as the inboard of the protuberance 45 of second engagement lugs and the end in the outside, on the inboard and the outside of 24B, but because second hinge member 2 turns to the position (leaving the position of 90 ° or 180 ° to the second place from primary importance) of regulation when going up, first, the first coupling recess 24A makes progress in the footpath of second hinge member 2 and movable member 4, the central portion of 24B is configured on the same position, so that the central portion of the length direction of protuberance 45 and the first coupling recess 24A, the central portion of 24B overlaps, therefore integrally be configured in the first coupling recess 24A with protuberance 45, compare when the inboard of 24B or the outside, can make the circle diameter of configuration protuberance 45, with the configuration second coupling recess 24A, the difference of the circle diameter of 24B is less.Therefore, second hinge member 2 and movable member 4 big diameter like that need not be configured to, the big footpathization of hinge means A can be prevented.In addition, can make each contact position of spheroid 6 and protuberance 45 and opposed faces 23, in circumference radially approaching mutually that with hinge axis 3 is the center.Particularly, in the present embodiment, because it is on the same circumference that protuberance 45 is configured in and disposes the circumference of spheroid 6 and the first coupling recess 24A, 24B, the both ends of protuberance 45 are given prominence to same length from the 1st coupling recess 24A, 24B to the radially inner side and the outside, thereby by spheroid 6 and protuberance 45, acting on the elastic force of the helical spring 5 on second hinge member 2, is that the center acts on symmetrically with hinge axis 3.Therefore, second hinge member 2 is rotated swimmingly.
Fig. 7 and Fig. 8 represent the second embodiment of the present invention.In the present embodiment, as shown in Figure 7, protuberance 45 configured in one piece are on the periphery of configuration spheroid 6.But protuberance 45 is configured to, when second hinge member 2 turns to assigned position (when primary importance is rotated 90 ° or 180 °), and Outboard Sections radially the overlapping of the end of the inboard of protuberance 45 and spheroid 6 at movable member 4.With it accordingly, the a pair of second coupling recess 25A, 25B are as shown in Figure 8, also be configured in the outside of circumference of the configuration first coupling recess 24A, 24B, and Outboard Sections radially the overlapping at second hinge member 2 of the end of the second coupling recess 25A, 25B inboard and the first coupling recess 24A, 24B.The also configurable inboard of protuberance 45 and the second coupling recess 25A, 25B at spheroid 6 and the first coupling recess 24A, 24B.Other structure is identical with above-mentioned first embodiment.
In the present embodiment, be configured in because of the second coupling recess 25A, 25B on the position in the outside of circumference of the configuration first coupling recess 24A, 24B, spheroid 6 can not engage with the second coupling recess 25A, 25B.In addition, when second hinge member 2 turned to assigned position, the end of protuberance 45 inboards overlapped with the first coupling recess 45A, 45B, but because of the end in protuberance 45 outsides contacts with opposed faces 23, protuberance 45 can not engage with the first coupling recess 24A, 24B.Therefore, second hinge member 2 can rotate between the primary importance and the second place swimmingly.In addition, be configured in because of the second coupling recess 25A, 25B on the outer fix of the first coupling recess 24A, 24B, even do not form guide channel 26, spheroid 6 can the second coupling recess 25A, 25B not engage yet.So, in the present embodiment, also can not form guide channel 26.
Because the end of protuberance 45 inboards is configured to upwards overlap with spheroid 6 and the first coupling recess 24A, 24B in the footpath of second hinge member 2 and movable member 4, therefore with protuberance 45 configured in one piece are compared in the situation in the outside of the first coupling recess 24A, 24B, can make the circle diameter of configuration protuberance 45 and the second coupling recess 25A, 25B, diminish with the difference of the circle diameter of configuration spheroid 6 and the first coupling recess 24A, 24B.Therefore, can prevent the big footpathization of hinge means and the balance deterioration that can prevent to act on helical spring 5 elastic force on second hinge member 2.
In addition, the present invention is not limited to the foregoing description, also change aptly in the scope that does not change its main idea.
For example, in the above-described embodiments, be by movable member 4 and 1 split of first hinge member are formed, make movable member 4 rotatable and connect movably on first hinge member to the axis direction (pivot center) of hinge axis, make movable member 4 relative second hinge members 2 (hinge member) rotatable, and connect movably to the pivot center direction, but also can make the movable member 4 and first hinge member 1 ground that forms as one whole as movable member, relative second hinge member 2 of this movable member is rotatable and can be approaching to the pivot center direction, leave movably and connect.In addition, when the hinge means of structure like this for example is used for portable phone, movable member can not be able to be rotated on the either party who send words portion and the portion of answering of portable phone and can be connected movably, will on the opposing party who send words portion and the portion of answering, be connected un-rotatably as second hinge member 2 of hinge member to the pivot center direction.Much less, 5 pairs of helical springs make first hinge member 1 and movable member 4 incorporate movable members to second hinge member, the 2 side application of forces.
In addition, in the above-described embodiments, used spheroid 6 as first engagement lugs, but also can be with the protuberance identical with protuberance 45 as first engagement lugs.
Have again, in the above-described embodiments, be that spheroid 6 and protuberance 45 are configured on the movable member 4, the first coupling recess 24A, 24B and the second coupling recess 25A, 25B are configured on second hinge member 2, but also spheroid 6 and protuberance 45 can be configured on the hinge member 2, the first coupling recess 24A, 24B and the second coupling recess 25A, 25b are configured on the movable member 4.
Utilizability on the industry
Hinge means of the present invention can be used as two parts, for example pocket telephones with portable machine The hinge means that words section and the section of being connected connect usefulness rotationally that send use.
