Background technology
As everyone knows, the display part of present display can be regulated the angle of inclination and is connected with support.For example, refer to Patent Document 1.
Patent documentation 1: the spy opens the 2000-242363 communique.
Such display is under support unit is placed on state on the face of setting, and display part is from face is set leaves and be supported parts carry.And, can be by shaking display part and change the angle of inclination freely to the support unit fore-and-aft direction, and can be adjusted to the user and see the only angle of picture.
Summary of the invention
In described conventional example, be provided with on the face place display after, grip display part with hand and regulate its angle of inclination.In a single day, then in each the use, just do not needing to readjust angle if in the display of placed type, be adjusted into desired angle.Yet under the situation of movable display, angle can change in the moving of carrying, perhaps can change the angle of display part wittingly for easy carrying, therefore, when being placed on mobile place at every turn, need be adjusted to desired angle with hand, regulate often and trouble.
Particularly nearest, also popularize to use WLAN (wireless local area network) LAN (Local AreaNetwork) in the family, like this, for example can envision the terminal equipment that is integral type with LCD and move the chance of using in the family and also increase.
The present invention is in view of described problem, and purpose provides hinge, with gemel support unit, the display of the operation that bothers when removing the angle of inclination of regulating display part.
Hinge of the present invention has: spindle unit; Rotate first rotatable parts that are installed in freely on this spindle unit; Be wound on the spindle unit and drive the first rotatable parts helical spring of first rotatable parts to primary importance; Rotate and to be installed in freely on the spindle unit, be fastened on second rotatable parts on first rotatable parts when the backward rotation of the direction that drives first rotatable parts from primary importance.Turn to the clamped position that engages with first rotatable parts when second rotatable parts, and further when the backward rotation of the direction that drives first rotatable parts, second rotatable parts and first rotatable parts are resisted first rotatable parts together and are rotated to the second place with helical spring actuating force.
In addition, with gemel support unit of the present invention has: hinge; With this hinged connecting portion; Be bearing in the support on the face of setting.And then hinge has: be fixed on the spindle unit on the connecting portion; Rotate first rotatable parts that are installed in freely on this spindle unit; Be wound on the spindle unit and drive the first rotatable parts helical spring of first rotatable parts to primary importance; Rotate and to be installed in freely on the spindle unit, at second rotatable parts that are fastened on first rotatable parts from primary importance during to the backward rotation of the direction that drives first rotatable parts.Turn to the clamped position that engages with first rotatable parts when second rotatable parts, and further when the backward rotation of the direction that drives first rotatable parts, second rotatable parts and first rotatable parts are resisted first rotatable parts together and are rotated to the second place with helical spring actuating force.
In addition, display of the present invention has: display part; Have connecting portion that connects this display part and the support unit that is bearing in the support on the face of setting; Hinge between the connecting portion of display part and support unit.And then hinge has: be fixed on the spindle unit on the connecting portion; Rotate first rotatable parts that are installed in freely on this spindle unit; Be wound on and drive the first rotatable parts helical spring of first rotatable parts on the spindle unit to primary importance; Rotate when being installed on the display part and be installed in freely on the spindle unit, at second rotatable parts that are fastened on during from primary importance on first rotatable parts to the backward rotation of the direction that drives first rotatable parts.When second rotatable parts turn to the clamped position that engages with first rotatable parts and during further to the backward rotation of the direction that drives first rotatable parts, second rotatable parts and first rotatable parts are resisted the helical spring actuating force of first rotatable parts together, rotate to the second place that the opening angle of display part and support unit is bigger than primary importance.
First rotatable parts are driven to primary importance by first rotatable parts with the twisting resistance of spring.The primary importance here is meant the position of opening minimum angles between the display part that is connected through the hinge and the support unit.Support unit prevents to be erected at that display part on the face of setting is toppled over and with desirable angle supporting display part.
Second rotatable parts are installed on the spindle unit, can turn to the second place freely via the position that engages with first rotatable parts midway from described primary importance.The second place here is meant the position of opening maximum angle between the display part that is connected through the hinge and the support unit.In addition, to arrive the state of the position that engages with first rotation be that open angle becomes state between the primary importance and the second place between the display part that is connected through the hinge and the support unit to second rotatable parts.
If display part is erected at when deadweight acts on second rotatable parts that are in primary importance when the display frame rear tilts on the face of setting, then second rotatable parts turn to the position that engages with first rotatable parts freely.At this moment, first rotatable parts stop on the primary importance with helical spring actuating force by first rotatable parts.When second rotatable parts turned to the position that engages with first rotatable parts, as long as opposing first rotatable parts do not act on second rotatable parts with the power of helical spring actuating force, second rotatable parts just no longer were rotated further.
If for example consider to be set at ergonomics (making the people cosily not be engaged in the science of work) to set the angle of inclination of the display part under the state that this second rotatable parts arrive the position that engage with first rotatable parts be desirable angle not tiredly, then need the display part setting be placed on angle that the deadweight that just can utilize display part on the face of setting makes display part automatically flare up meet described ergonomic optimum angle of inclination.
Want to make display part to be inclined to the angle bigger,, for example push below oblique on the top of display part and apply the power that display part is more tilted with hand then as power greater than display part deadweight than described angle.So first rotatable parts are resisted first rotatable parts and are rotated to the second place with helical spring actuating force.At this moment, be fastened on first rotatable parts second rotatable parts also with first rotatable parts one in the same way the second place rotate.
Rotate to this second place by first, second rotatable parts, open angle is than bigger by the open angle of the deadweight of described display part between display part and the support, and display part also correspondingly tilts more.
If make sweptback display part in face of side return setting, then first rotatable parts turn back to primary importance by first rotatable parts with helical spring actuating force.Primary importance be opened and be turned back to second rotatable parts also can by the effect of display part deadweight.
Thereby, can under the state of the opening angle that reduces display part and support unit, carry the packing when perhaps transporting or the keeping when not using etc.Its result can carry with the state of compactness, in addition, and the save spaceization in the time of can realizing packing and taking care of.
In addition, if form the structure that second rotatable parts stably remain on primary importance, then when carrying, can prevent because the vibration that occurs of not wishing of second rotatable parts causes support unit and display part impact sound and breakage.
As such structure, for example can enumerate the structure that the rotation of second rotatable parts is applied frictional force.More specifically for example can consider to be provided with to the parts of second rotatable parts with face contact crimping.The friction intensity of force that produces at the pressure contact portion of this welded part and second rotatable parts is set to allow that second rotatable parts turn to the position that engages with first rotatable parts by the deadweight of display part from primary importance, and for example turns back to primary importance by hand rotation from this clamped position.
Perhaps also can form the structure that drives second rotatable parts to primary importance with helical spring by second rotatable parts.When releasing makes second rotatable parts when primary importance turns to the power of the position that engages with first rotatable parts, second rotatable parts automatically turn back to primary importance by second rotatable parts with helical spring actuating force.To make second rotatable parts to the rotated position that engages with first rotatable parts in order allowing, to make second rotatable parts littler than described first rotatable parts with helical spring coefficient of elasticity (spring strength) with helical spring by the deadweight of display part.
Under the situation of this structure, if mention display, then can automatically form the primary importance of opening angle minimum between support unit and the display part from face is set, do not need to make support unit turn to primary importance with hand.
In addition, if in support unit as with the support that the face contact site is set on roller is installed, then along with the display part tilted rearward, support unit moves and adjusts to easily desirable opening angle by this roller smoothly backward being provided with on the face.
Can use the material of materials such as rubber, resin, metal as roller.If use elastomeric material especially then can improve roller and frictional force between the face is set, suppress roller and dally being provided with on the face, the influence that plane materiel matter is not set is moved being provided with on the face of support unit smoothly.
If hinge of the present invention is used to adjust the angle of inclination of display part, the angle of inclination is regulated in the deadweight in the time of then can utilizing display part to fall backward automatically.
If with gemel support unit of the present invention as the support unit of display part, then can the deadweight when utilizing display part to fall be backward regulated the state support display part at angle of inclination automatically.
According to display of the present invention, only need the display part setting is placed on the face of setting, deadweight when utilizing display part to fall backward automatically makes first rotatable parts of hinge rotate, and interlock makes support unit retreat mobilely on the face being provided with therewith, can make display part form desirable angle of inclination.And then first rotatable parts by hinge can stably keep described state with helical spring actuating force.

As shown in Figure 4, hinge 10 is connected on support unit 3 and the face that display part 2 matches.Specifically, two bights of the upside in four bights of support unit 3 near connect hinge 10 respectively.
Hinge connection in support unit 3 is formed with protuberance 3c (with reference to Fig. 5), and as shown in figure 10, this protuberance 3c connects columnar connecting portion 3a integratedly.Therefore, connecting portion 3a is fixed on the support unit 3 by protuberance 3c.
As shown in figure 10, an end of stationary shaft member 20 embeds in this connecting portion 3a and fixes.Spindle unit 20 stretches out and fixes from connecting portion 3a, and threaded engagement has nut 21 on its other end.
Axial substantial middle rotated position at spindle unit 20 is equipped with first rotatable parts 22 freely.The ring portion 23 and the tube portion 24 of first rotatable parts 22 link into an integrated entity.Spindle unit 20 passes in the medium pore and tube portion 24 of ring 23.
On the periphery of the ring portion 23 of first rotatable parts 22, be formed with a plurality of recesses 25,27,28 (with reference to Figure 12).Recess 25 has the function that first rotatable parts is embedded the elasticity holding section with an end of helical spring 29; As shown in figure 11, recess 27 disposes the holding section 32 of second rotatable parts 30; Recess 28 disposes the leading section (with reference to Figure 12) with the integrally formed catch 3b of the connecting portion 3a of support unit 3.
In spindle unit 20, on the position between the ring portion 23 of the connecting portion 3a of support unit 3 and first rotatable parts 22, be wound with first rotatable parts with helical spring (being designated hereinafter simply as helical spring) 29.One end of helical spring 29 is embedded in engaging in the described recess 25 that forms on the ring portion 23 of first rotatable parts 22, and the other end inserts the interior engaging of connecting portion 3a of support unit 3.
Thus, helical spring 29 is to drive first rotatable parts 22 around axial twisting resistance to the direction of arrow shown in Figure 10.First rotatable parts 22 are subjected to this twisting resistance and rotate around the axial arrow label orientation of spindle unit 20, touch by the inner wall part 28a with recess 28 and limit it be rotated further on described catch 3b.
In spindle unit 20, from tube portion 24 sides endless member 33, second rotatable parts 30, endless member 34 and packing ring 35 are installed successively on the tube portion 24 of first rotatable parts 22 and the position between the nut 21.
Second rotatable parts 30 are sandwiched in to rotate between two endless members 33,34 and are installed in freely on the spindle unit 20, adjust the pushing force of 34 pairs second rotatable parts 30 of described endless member and rotate relative to spindle unit 20 to allow second rotatable parts 30.
Form the holding section 32 (with reference to Figure 11) that the recess 27 to described first rotatable parts 22 stretches out on second rotatable parts 30, the leading section of this holding section 32 is configured in the recess 27.Rotate relative to spindle unit 20 by second rotatable parts 30, thereby the leading section of this holding section 32 is moved between relative two inner wall part 27a, the 27b of recess 27.
Second rotatable parts 30 form long slab shape from the part that is installed on the spindle unit 20 along extending radially outwardly of spindle unit 20, and its extended front portion curves the right angle substantially, forms the installation portion 36 that display part 2 is installed.
(action of hinge and support unit)
When external force did not act on support unit 3, hinge 10 was a state shown in Figure 12, and this is that as shown in Figure 5 display part 2 and support unit 3 opens the state of the primary importance of minimum angles.
In this primary importance, first rotatable parts 22 drive arrow label orientation in Figure 10 by the twisting resistance of helical spring 29, shown in Figure 12 (a), touch by the inner wall part 28a with recess 28 and to limit it be rotated further on the catch 3b of support unit 3.
Shown in Figure 12 (a), be in its holding section 32 touches the inner wall part 27a of the recess 27 that forms on first rotatable parts 22 position at second rotatable parts 30 on the primary importance.
And, as shown in Figure 5, if display part 2 be erected at be provided with that face S goes up and backward (right-hand among the figure) deadweight when toppling over work, then second rotatable parts 30 are to the backward rotation of arrow shown in Figure 10, and the holding section 32 of second rotatable parts 30 is mobile to position that the inner wall part 27b with the recess 27 that forms at first rotatable parts 22 touches (position that first rotatable parts 22 engages) shown in Figure 13 (a) from the position shown in Figure 12 (a).
Promptly, deadweight when toppling over backward by display part 2, the roller 15 of support unit 3 is being provided with slip rearward on the face as illustrated in fig. 6 from the state of Fig. 5, and display part 2 automatically (just display part 2 is erected on the face of setting) is inclined to desired angle shown in Figure 6, and remains on this state.
Only otherwise on second rotatable parts 30 and first rotatable parts 22, apply the rotatory force of the driving of opposing helical spring 29, the only deadweight of toppling over by display part 2, support unit 3 can not continue on the face S to retreat from position shown in Figure 6 being provided with.Therefore, at the state of Fig. 6, Figure 13, it is motionless that the actuating force of first rotatable parts 22 by helical spring 29 stops at primary importance.
For example, if considered that the angle of inclination that ergonomics (making the people cosily not be engaged in the science of work) is set in the display part 2 that the state of Fig. 6 keeps is desirable angle not tiredly, so, only need display part 2 erect to be placed on face S is set goes up the deadweight that just can utilize display part 2 and the angle of display part 2 is automatically opened become and meet described ergonomic optimum inclination angle.
Make display part 2 with the time in hope, need use the power bigger, for example push the power that the top 68 of members of frame 66 makes display part 2 be subjected to more tilting to oblique below with hand than the deadweight of display part 2 than described bigger angle tilt.
By this power, the reverse rotatory force to arrow mark shown in Figure 10 of the twisting resistance of opposing helical spring 29 acts on second rotatable parts 30 and first rotatable parts 22.This rotatory force does not act directly on first rotatable parts 22 and acts directly on second rotatable parts 30 strictly speaking, being in holding section 32 with second rotatable parts 30 of first rotatable parts, 22 clamped positions touches on the inner wall part 27b of the recess 27 of first rotatable parts 22, push this inner wall part 27b by this holding section 32 clockwise direction in Figure 13 (a), and the twisting resistance of first rotatable parts, 22 opposing helical springs 29 is rotated.
Thus, hinge 10 becomes state shown in Figure 14, and this is that the display part 2 and the support 3 that are in as shown in Figure 7 open the state of the second place of maximum angle.Shown in Figure 14 (a), on touching baffle plate 3b at support unit 3, the inner wall part 28b of first rotatable parts 22 on the second place by its recess 28 be limited to be rotated further.Second rotatable parts 30 touch on the inner wall part 27b of the recess 27 of first rotatable parts 22 by its holding section 32 and are limited to be rotated further.
In addition, even do not open the second place state that reaches shown in Figure 7 fully, deadweight that also can be by display part 2 and face S is set and support unit 3 between contact friction remain on the state that opens intermediate angle.
In addition, because support unit 3 for example is provided with face S by roller 15 contacts of rubber system, do not influenced so the material of face S is not set, carry out from described Fig. 5 to Fig. 6 easily so that the state from Fig. 6 to Fig. 7 retreat mobilely, and can carry out the tilting action of display part 2 smoothly.
If make sweptback display part 2 return side setting in front, then the first dress dynamic component 22 returns primary importance by the twisting resistance of helical spring 29.The action of following these first rotatable parts 22 to return to primary importance, the holding section 32 of second rotatable parts 30 turns back to position shown in Figure 13 by the counter clockwise direction pushing of inner wall part 27b in Figure 14 of the recess 27 of first rotatable parts 22.
And then, if display part 2 is opened by the deadweight effect, then by for example pushing display part 2 sides to and can make second rotatable parts 30 return primary importance with handgrip support unit 3.As shown in Figure 5, can reduce display part 2 and support unit 3 open angles, at carrying display 1 under the state that dwindles display 1 whole depth size, carry out transportation and packing or when not using, take care of by above operation.
Be under the state of this primary importance, first rotatable parts 22 keep primary importance by the actuating force of helical spring 29, second rotatable parts 30 keep primary importance by the frictional force with endless member 34, thereby can stably keep display part 2 and support 3 shown in Figure 5 to open the state of minimum angles.Its result can prevent that support unit 3 from shaking, and can prevent that this from shaking breakage and the abnormal sound that causes when carrying.And then, the time do not need support unit 3 is pressed against the parts of display part 2 sides in packing, and seek the save spaceization of packing.

(action of hinge and support unit)
When external force did not act on support unit 3, hinge 40 was in state shown in Figure 19, and this is that as shown in Figure 5 display part 2 and support 3 opens the state of the primary importance of minimum angles.
On this primary importance, first rotatable parts 42 drive the direction of arrow in Figure 17 by the twisting resistance of helical spring 29, and shown in Figure 19 (a), the inner wall part 48a of recess 48 is limited to be rotated further by touching on the catch 3b of support unit 3.
Second rotatable parts 50 are direction of arrow driving in Figure 17 by the twisting resistance of helical spring 55, and as shown in figure 19, holding section 52 is limited to be rotated further by touching on the inner wall part 47a of recess 47.
And, as shown in Figure 5, if display part 2 be erected at be provided with that face S goes up and backward (right-hand among the figure) deadweight when toppling over work, then the actuating force of second rotatable parts 50 opposing helical springs 55 and in Figure 17 the backward rotation of arrow, the holding section 52 of second rotatable parts 50 is mobile to position that the inner wall part 47b with the recess 47 that forms at first rotatable parts 42 touches (position that first rotatable parts 42 engages) shown in Figure 20 (a) from the position shown in Figure 19 (a).
Promptly, deadweight when toppling over backward by display part 2, the roller 15 of support unit 3 is being provided with slip rearward on the face as described in Figure 6 from the state of Fig. 5, and display part 2 automatically (just display part 2 is erected at and is provided with on the face S) is inclined to desired angle shown in Figure 6, and remains on this state.
Only otherwise on second rotatable parts 50 and first rotatable parts 42, apply opposing drives the rotatory force of actuating force from the helical spring 29 of first rotatable parts 42 to primary importance, the only deadweight of toppling over by display part 2, support 3 can not continue to draw back from position shown in Figure 6 being provided with on the face S.Therefore, in the state of Fig. 6, Figure 20, it is motionless that the actuating force of first rotatable parts 42 by helical spring 29 stops at primary importance.
For example, if considered that the angle of inclination that ergonomics (making the people cosily not be engaged in the science of work) is set in the display part 2 that the state of Fig. 6 keeps down is desirable angle not tiredly, then only need display part 2 erect to be placed on face S is set goes up the deadweight that just can utilize display part 2 and the angle of display part 2 is automatically opened become and meet described ergonomic optimum inclination angle.
Make display part 2 with the time in hope, need use the power bigger, for example the power that makes display part 2 be subjected to more tilting to oblique below by the top 68 of press box 66 with hand than the deadweight of display part 2 than described bigger angle tilt.
By this power, the reverse rotatory force to arrow mark shown in Figure 17 of resisting the actuating force of helical spring 29,55 is acted on second rotatable parts 50 and first rotatable parts 42.Strictly speaking, this rotatory force does not act directly on first rotatable parts 42, and act directly on second rotatable parts 50, being in holding section 52 with second rotatable parts 50 of first rotatable parts, 42 clamped positions touches on the inner wall part 47b of the recess of first rotatable parts 42, push this inner wall part 47b by this holding section 52 clockwise direction in Figure 20 (a), and the twisting resistance of first rotatable parts, 42 opposing helical springs 29 is rotated.
Thus, hinge 40 becomes state shown in Figure 21, and this is that the display part 2 and the support 3 that are in as shown in Figure 7 open the state of the second place of maximum angle.Shown in Figure 21 (a), first rotatable parts 42 touch on the catch 3b of support unit 3 by the inner wall part 48b with its recess 48 and are limited to be rotated further in the second place.Second rotatable parts 50 are limited to be rotated further by its holding section 52 being touched on the inwall 47b of the recess 47 of first rotatable parts 42.
In addition, even do not opening up into the second place shown in Figure 7 fully, deadweight that also can be by display part 2 and face S is set and support unit 3 between contact friction, and remain on the state that opens intermediate angle.
In addition, because support unit 3 for example is provided with face S by roller 15 contacts of rubber system, so the material that face S is not set does not influence, and carry out from described Fig. 5 to Fig. 6 easily so that the state from Fig. 6 to Fig. 7 retreat mobilely, can carry out the tilting action of display part 2 smoothly.
If make sweptback display part 2 return side setting in front, then drive force first rotatable parts 42 by helical spring 29,55 return primary importance.The action of following these first rotatable parts 42 to return to primary importance, the holding section 52 of second rotatable parts 50 is pushed by the counter-clockwise direction of inner wall part 47b in Figure 21 of the recess 47 of first rotatable parts 42, and then returns position shown in Figure 20 by the drive force of helical spring 55.
And then if display part 2 is opened by the deadweight effect, then actuating force second rotatable parts 50 by helical spring 55 automatically return primary importance.As shown in Figure 5, can reduce display part 2 and support unit 3 open angles, at carrying display 1 under the state that dwindles display 1 whole depth, carry out transportation and packing or when not using, take care of by above action.
Be under the state of this primary importance, because first rotatable parts 42 keep primary importance by the actuating force of helical spring 29, second rotatable parts 50 keep primary importance by the actuating force of helical spring 55, so can stably keep display part 2 and support unit 3 shown in Figure 5 to open the state of minimum angles.Its result can prevent that in carrying support unit 3 from shaking and can prevent this breakage and the abnormal sound that causes that shake.And then, the time do not need support unit 3 is pressed against the parts of display part 2 sides in packing, seek the save spaceization of packing.
In addition, in the present embodiment, because if display part 2 is opened by the deadweight effect, then second rotatable parts 50 turn back to primary importance by the actuating force of helical spring 55, so need not as described first execution mode, shift display part 2 sides onto, but when mentioning display 1, automatically form state shown in Figure 5 with handgrip support unit 3.
Various embodiment of the present invention more than has been described, the present invention is not limited to these certainly, can carry out various distortion according to technological thought of the present invention.
The quantity of hinge 10,40 is not limited to two, can more than one or three and three.The installation position of hinge also is not limited to the transverse ends portion of support unit 3, also can be installed in central part.
In addition, support unit 3 is not limited to frame (ring) shape, also can be the shape in the middle of not hollowing out, and for example can be rectangle.
In addition, also can be on display 1 closed one freely connect keyboard as input unit.Certainly, this keyboard is connected with display 1 with line or also can be wireless.
