It can be that the center is turned round in the preset range of left and right directions with gyroaxis 21a that this arm 21 forms.In this example, the left end of the revolution range of this arm 21 forms enable possition O (state shown in Figure 3), right-hand member forms fastening position C (state shown in Figure 7), respectively (in this example to the enable possition of the body 11 of answering the door, be the position under the state that door body 11 relatively moves to the right in each figure) and fastening position (in this example, being the position under the relatively mobile to the left state of door body 11 in each figure).That is, be benchmark with the position of gyroaxis 21a, be enable possition O at the front end (diagram upper end) of arm 21 when being positioned at the diagram left, being positioned at when right-hand is fastening position C.
And arm 21 concerns according to the position with temporary fixed mechanism 25, as shown in Figure 9, can further move towards left by more above-mentioned enable possition O.
In this example, front (diagram upper end side) at above-mentioned arm 21, mode with the 2 relative plate body clampings by constituting arm 21, form fixed part 21b cylindraceous, this fixed part 21b is maintained in the temporary fixed mechanism 25 that is located in the doorframe 12, specifically be among the arm fixing groove 25c that remains in the temporary fixed mechanism 25, but self-closing doors body 11 thus.
In addition, fixed part 21b in this example is configured in the outside of axial region 21b1 and axial region 21b1, having can be with respect to the 21b2 of roller portion of this axial region 21b1 rotation, as described later, when fixed part 21b is configured among the arm fixing groove 25c of temporary fixed mechanism 25, can make left wall 25a or the right-hand wall 25b revolution of the 21b2 of this roller portion, therefore fixed part 21b is moved up and down with respect to temporary fixed mechanism 25.
The shape of arm 21 is not limited to the shape in this example, for example, as Figure 11～shown in Figure 14, can be with various scheme implementations.Again, in this example, though with the upper end of arm 21 as fixed part 21b, also can form fixed part 21b in the position beyond the upper end of the centre of arm 21 etc.
Moreover, in this example, carrying out the small-sized purpose that turns to the relation of the actuating range of force application mechanism 23 or snubber 24 and with shutoff device body 2a, arm 21 is not simple straight clavate shape, but forms curved shape as shown.Particularly, in state shown in Figure 3, by as the base end part 21x of base end side (diagram lower end side), change the leading section 21z that extends on direction ground below roughly and constitute continuously and towards illustrated at the continuous pars intermedia 21y in front and the diagram upper left side of base end part 21x with to the front of pars intermedia 21y.On base end part 21x, be connected force application mechanism 23 by gyroaxis 21a with force application mechanism installation portion 21c respectively as above-mentioned, connect snubber 24 by snubber installation portion 21e.Above-mentioned fixed part 21b is set on leading section 21z again.
The connection of above-mentioned force application mechanism 23 is to be undertaken by the upper end 23b that force application mechanism 23 is installed on the force application mechanism installation portion 21c that is located on the arm 21.At this, this force application mechanism installation portion 21c, when arm 21 is positioned at enable possition O, represent as Fig. 3, gyroaxis 21a with respect to arm 21 is positioned at the top, when fastening position C moves, is that center turn round and downwards move with the gyroaxis 21a of arm 21 at arm 21, arrives the state that Fig. 7 represents.
On the other hand, the device as corresponding to above-mentioned holding section 26a is provided with arm maintaining body 27 on housing 22.This arm position holding mechanism 27, as shown in Figure 3, when arm 21 is positioned at enable possition O, the bend 27a as the part of arm position holding mechanism 27 can be fastened on the holding section 26a of arm 21, the position of arm 21 is remained on O place, enable possition.
Arm position holding mechanism 27 is leaf spring 27 in this example, and base end side (diagram left end side) is fixed on the housing 22.
This leaf spring 27 has with the outstanding bend 27a that forms of mode towards arm 21.Shape such as the Fig. 3 of concrete leaf spring 27 in this example represent, be positioned at arm 21 under the situation of enable possition O, from the part of fixing with respect to the diagram left of housing 22, at first towards the right-hand extension of diagram, bend to V-shape in its front, the part after this bending forms bend 27a.And, this bend 27a as shown in Figure 3, can with engage as the holding section 26a that is formed on above-mentioned arm 21 upper recess.
The engaging of bend 27a and holding section 26a owing to the power effect downwards that the holding section 26a to arm 21 of leaf spring 27 applies is strengthened, therefore can positively remain on arm 21 on the O of enable possition.And, the direction of the above-mentioned active force of leaf spring 27 so long as and the gyratory directions of arm 21 direction of intersecting get final product, but the butt joint early work is under the situation of the opening direction application of force of circular arc of gyratory directions of arm 21, because the fastening state of arm 21 and leaf spring 27 is difficult for breaking away from, so better.
In addition, in this example, represent that when arm 21 was positioned at enable possition O, the gyroaxis 21a by arm 21 and the imaginary axis at the center of force application mechanism 23 were roughly consistent at above-below direction as Fig. 3.Therefore, the arm 21 under this state is in the neutral condition of not carrying out the application of force by force application mechanism 23, only applies the active force of leaf spring 27 on arm 21.Therefore, as engaging between the holding section 26a of the bend 27a of the leaf spring 27 that carries out and arm 21 above-mentionedly, along with moving of door body 11, abut at the fixed part 21b of arm 21 (with reference to Fig. 5) till the left wall 25a of temporary fixed mechanism 25, only otherwise the external force that applies other just is not easy to come off.
The above-mentioned position maintaining part 26a and the various schemes of arm position holding mechanism 27 go up as long as arm 21 can be remained on enable possition O, are not limited to the mechanism in this example, can carry out various changes ground and implement.For example, as shown in figure 11, arm position holding mechanism 27 can be following structure, promptly, one end has abutting part 27b, the other end has the 27c of hook portion, between abutting part 27b and the 27c of hook portion, form the fulcrum 27d that can be supported on freely to rotate on the shutoff device body 2a, this abutting part 27b, the 27c of hook portion, fulcrum 27d form the roughly V-shape with leg-of-mutton position relation, when arm 21 is positioned at enable possition O, the position maintaining part 21b of the 27b of hook portion hook arm 21, the position that can keep arm 21.
And, shown in Figure 12 (A), position maintaining part 21e is the tabular device with fitting projection 21e1, this fitting projection 21e1 is to be provided with to the outstanding mode in the left side of arm 21, arm position holding mechanism 27 can be following structure, promptly, on position maintaining part 21e and part that fitting projection 21e1 contacts, chimeric recess 27e is set, when arm 21 is positioned at enable possition O, make the chimeric recess 27e of the fitting projection 21e1 of arm 21 and arm position holding mechanism 27 chimeric as Figure 12 (B) expression, resist the active force of force application mechanism 23 thus, the position of arm 21 is remained on previous status.In addition, arm position holding mechanism 27 also can be for having the mechanism of magnet, with respect to arm position holding mechanism 27 with the part of magnetic force absorption arm 21, keep arm 21 with this.
In this example, represent,, be not limited to this routine structure with respect to the mounting method of the force application mechanism 23 of arm 21 though this force application mechanism installation portion 21c is arranged on the cardinal extremity place near arm 21 as Fig. 3.For example, as Figure 11～shown in Figure 13, force application mechanism installation portion 21c is arranged on the close front end place of arm 21.And, in mechanism shown in Figure 14, force application mechanism installation portion 21c is arranged on cardinal extremity (diagram lower end) side of gyroaxis 21a, but force application mechanism 23 is arranged on the diagram left side of arm 21.Like this, can carry out various changes and enforcement.
Again, force application mechanism 23 is not limited to as this routine helical spring, for example also can use the rubber-like resin of the spring of other kinds such as disc spring that are installed on the gyroaxis 21a or rubber etc., and not limit the installation site.In addition, with this example on the contrary, also can utilize the compressive force of spring.
Again, represent, also can change tensile force or the compressive force that force application mechanism 23 is had thus at a distolateral position adjusting mechanism 23 that is provided with of force application mechanism 23 as Figure 10.In illustrated mechanism, utilize adjustment screw 28b to be pre-formed removable state the movable axis 28a that the lower end 23a of helical spring 23 is installed, can adjust the displacement of helical spring 23 thus with respect to housing 22.Therefore, the translational speed of arm 21 can be adjusted, relatively, the closing velocity of a body 11 can be adjusted.
As described later, as the fixed part 21b of arm 21 front ends as shown in Figure 5, form the state on the arm fixing groove 25c that remains on the temporary fixed mechanism 25 that is located on the doorframe 12, by the application of force, arm 21 moves towards fastening position C arm 21 thus in the mode that stretched by force application mechanism 23.Accompany therewith, make the door body 11 that shutoff device body 2a is installed move and close along doorframe 12.And, when this is closed, revolution action till from the enable possition O (icon left) of arm 21 to fastening position C (right-hand) is owing to the cushioning effect of snubber 24 is slowed down, therefore moving of door body 11 also is decelerated, the opening side end face 11a of door body 11 can not collide hastily to the end face 12a of doorframe 12, can positively close.Again, owing to make arm 21 unlikely mobile hastily by snubber 24, so door body 11 can not produce resiliences with respect to doorframe 12.
In this example, represent,, be not limited to this routine structure with respect to the mounting method of the snubber 24 of arm 21 though snubber abutting part 21e is set to the front of the force application mechanism installation portion 21c in the base end part 21x of arm 21 as Fig. 3.For example, as Figure 11～shown in Figure 13, movable rod 24a also can be directly with arm 21 bindings, but carry out the transmission of power by a part of butt with arm 21.Again, represent, also snubber abutting part 21e can be set, link movable rod 24a at this snubber abutting part 21e in the front of arm 21 as Figure 14.And, also can link indirectly with respect to arm 21 via gear or connecting rod etc., can carry out various changes and enforcement.Again, with above-mentioned force application mechanism 23 similarly, for this snubber 24, can adjust buffer capacity by being redefined for, adjust the closing velocity of a body 11 with this.
Again, snubber 24 also can be following device, promptly, even under the situation of moving on the either direction of the left and right sides, also can bring into play the device of cushioning effect at arm 21, perhaps also can be following device, that is, and as the interior device that is provided with one-way clutch, slow down when fastening position C (right-hand) is mobile at arm 21, at the device that when enable possition O (left) is mobile, then can not slow down.
Temporary fixed mechanism 25 is mounted in the parts on the doorframe 12 in this example, is used for carrying out arm 21 temporarily fixing with respect to doorframe 12.In this example, represent as Fig. 3, have outstanding the 1st projection 251 and the 2nd projection 252 downwards from base portion 25f, have the arm fixing groove 25c of opening downwards, this groove 25c is by carrying out clamping as the left wall 25a of the right flank of the 1st projection 251 with as the right-hand wall 25b of the left surface of the 2nd projection 252.That is, arm fixing groove 25c limits by left wall 25a and the right-hand wall 25b that extends towards the below of base portion 25f.
Below this temporary fixed mechanism 25, be formed with importing inclined-plane 25e on the illustrated right again.This imports the skew up and down that inclined-plane 25e absorbs shutoff device body 2a and temporary fixed mechanism 25, the fixed part 21b of arm 21 successfully can be imported among the arm fixing groove 25c.This importing inclined-plane 25e is formed on bottom than on the higher position of the lower left wall 25d of the diagram lower left of arm fixing groove 25a.This is the below of passing through to import inclined-plane 25e for the fixed part 21b that makes arm 21, and it is imported to arm fixing groove 25c.
In addition, the fixed part 21b that also can form at arm 21 by import inclined-plane 25e below the time, even fixed part 21b also can keep the state in gap with respect to importing inclined-plane 25e butt.At this, Fig. 9 represent with shutoff device body 2a and temporary fixed mechanism 25 near the above-below direction of device shown in Figure 3 situation about being configured.Shown in dotted line, the fixed part 21b that is positioned at the arm 21 of enable possition O is connected to constantly and imports on the inclined-plane 25e, and is imported into arm fixing groove 25c.
Base portion 25f in this example, shown in Fig. 8 (C), (D), width dimensions (depth dimensions) the earth of comparing with the 1st projection 251 and the 2nd projection 252 forms, have can with the bearing surface 25f1 of the following 12b butt of doorframe 12.And in base portion 25f, the part of the left of the 1st projection 251 (with reference to Fig. 8 (B)) forms to extend the 25f2 of portion is set.Be provided with among the 25f2 of portion in this extension, begin distance till the diagram left end of base portion 25f from the left wall 25a as the right flank of the 1st projection 251, the left position from the fixed part 21b of arm 21 when forming with shown in Figure 7 closing begins the consistent size of distance till the opening side end face 11a of door body 11.Therefore, as shown in Figure 5, the diagram left end portion 25f3 of the 25f2 of portion and the end face 12a butt of doorframe 12 are set, can easily carry out the location of temporary fixed mechanism 25 with respect to the left and right directions of doorframe 12 by making this extension.
And also can on the bearing surface 25f1 of base portion 25f, form aligned in position groove 25g, this aligned in position uses groove 25g shown in Fig. 8 (A), (D), central authorities at bearing surface 25f1, be provided with in mode along the length direction of bearing surface 25f1, protuberance (not shown) on making it and being arranged on doorframe 12 is consistent, can easily carry out the location of temporary fixed mechanism 25 with respect to the depth direction of doorframe 12 thus.In this example,, be not limited thereto, also recess or protuberance can be set discontinuously, on doorframe 12, be provided with and above-mentioned recess or chimeric protuberance or the recess of protuberance though implement with groove 25g as aligned in position.
Again, arm fixing groove 25c makes base portion 25f run through above-below direction shown in the dotted line of Fig. 8 (A)～(C) or Fig. 3 and Fig. 5～Fig. 7, and this part that runs through is as through hole 25h.Roughly being dimetric hole though this through hole 25h in this example shown in Fig. 8 (A), (C), forms by what base portion 25f surrounded, being not limited thereto, for example also can be the hole towards side opening form.
By forming this through hole 25h, in Fig. 7, represent as dotted line, utilize position relation with shutoff device body 2a, even as under the fixed part 21b of the front end of arm 21 and the situation about comparing usually above being positioned at, owing to have the remaining of the thickness part that is equivalent to base portion 25f, therefore also can avoid the collision of fixed part 21b.In addition, also the size up and down of temporary fixed mechanism 25 can be formed the amount of the thickness part of slightly little this base portion 25f, it is outstanding that this temporary fixed mechanism 25 is not easy from doorframe 12.
And, on the diagram left part of the 2nd projection 252,, be formed with the narrow width part 25i of reduced width as Fig. 8 (C) expression.The width dimensions (depth dimensions) of this narrow width part 25i forms the interval (inside dimension) less than the 2 relative plate bodys that constitute arm 21.By forming this narrow width part 25i, represent that as Fig. 6 even under the overlapping situation of temporary fixed mechanism 25 and arm 21, but still between keeps the gap.Therefore, can be by being equivalent to the play (Swam び in this gap) be absorbed in the warpage or the distortion that produce in a body 11 or the doorframe 12, can prevent the bad action of arm 21.
At this, represent as Fig. 9, shutoff device body 2a and temporary fixed mechanism 25 near the above-below direction of device shown in Figure 3 under the situation about being configured, be connected to constantly at the fixed part 21b of arm 21 on the lower right wall 25d of temporary fixed mechanism 25, when arm 21 moved towards the diagram left, arm 21 was moved by the left to common enable possition O.Therefore, the movable rod 24a of snubber 24 compares with state shown in Figure 3, forms the state of further being pulled out.In case beyond the mark this movable rod 24a is pulled out, then snubber 24 will cause fault.Therefore, be provided with on housing 22 and open side door shelves 22a, make a part and these unlatching side door shelves 22a butt of arm 21, it is mobile to prevent that thus surpassing of arm 21 from needing.In this example, in housing 22, a part of double as in diagram left side is for opening side door shelves 22a, but other member different with housing 22 also can be set.
Again,, be provided with and close side door shelves 22b, make arm 21 right-hand mobile, the unlikely fault that causes snubber 24 to the diagram of common fastening position C with similarly above-mentioned.In this example, in housing 22, a part of double as on diagram right side is for closing side door shelves 22b.
Then, the action to the shutoff device 2 of the switch motion that is accompanied by a body 11 describes.
Along with door body 11 moves towards fastening position from the enable possition, arm 21 is from state shown in Figure 3, forms the fixed part 21b that represents as Fig. 5 and is configured in state among the arm fixing groove 25c of temporary fixed mechanism 25.At this, the door body 11 that is provided with shutoff device body 2a further moves towards fastening position (icon left), therefore causes the collision of the left wall 25a of the fixed part 21b of arm 21 and temporary fixed mechanism 25.Thus, the engaging of the holding section 26a of the bend 27a of leaf spring 27 and arm 21 is broken away from.And then, by door body 11 towards the moving of diagram left, arm 21 moves towards fastening position C side (icon is right-hand).Under this state, the gyroaxis 21a of the imaginary axial ratio arm 21 by force application mechanism 23 centers further moves towards right-hand, therefore the active force of force application mechanism 23 acts on the arm 21, makes arm 21 begin the revolution towards fastening position C from enable possition O.When 21 revolutions of this arm, fixed part 21b forms the left wall 25a that is temporarily fixed mechanism 25 and the state of right-hand wall 25b clamping, does not move on left and right directions, only can move at above-below direction.Thus, under the state that fixed part 21b is remained in the temporary fixed mechanism 25, particularly, under the state that is connected on the right-hand wall 25b, make arm 21 rotations, form from Fig. 5 to state shown in Figure 6.That is, be appreciated that this right-hand wall 25b is as the fulcrum that is used for the fixed part 21b of supporting arm part 21.
Along with the revolution of this arm 21, can make the door body 11 that is provided with shutoff device body 2a move, close a body 11 (with reference to Fig. 7) towards the diagram left.The revolution of above-mentioned arm 21 continues to be subjected to the cushioning effect of the active force and the snubber 24 of force application mechanism 23, till proceeding to fastening position C automatically, therefore even under the more weak situation of externally applied forces in order to close a body 11, also can positively make arm 21 be turned back to fastening position C, fully close a body 11.
On the other hand, with above-mentioned opposite when opening door body 11, begin to be changed to the way meta that reaches unlatching from the fastening position of door body 11 and end, also with similarly above-mentioned, temporary fixed mechanism 25 is keeping keeping the state of the fixed part 21b of arm 21.Therefore, with on the contrary above-mentioned, be connected at fixed part 21b under the state on the left wall 25a of temporary fixed mechanism 25, along with door body 11 towards the moving of opening direction, arm 21 from fastening position C (icon is right-hand) revolution (from Fig. 7 through the state of Fig. 6) to Fig. 5 to enable possition O (icon left).At this, the bend 27a of leaf spring 27 engages with the holding section 26a of arm 21, fixing arm 21 under state originally shown in Figure 3.Then, in this state, such as already explained, because the gyroaxis 21a of arm 21 is roughly consistent with the imaginary axis at the center of passing through force application mechanism 23, therefore arm 21 is in the neutral condition of not passing through force application mechanism 23 application of forces, only engaging of the holding section 26a of the bend 27a by this leaf spring 27 and arm 21 just can prevent that arm 21 from turning back to the origin-location.
And, under the state of arm 21 till being shifted as shown in fig. 5 left, the below of fixed part 21b by the importing inclined-plane 25e of temporary fixed mechanism 25, move towards the right-hand of temporary fixed mechanism 25, open a door body 11.
And, represent as Fig. 9, under the situation that shutoff device body 2a and temporary fixed mechanism 25 is configured near the above-below direction of device shown in Figure 3, as previously described, when the fixed part 21b of arm 21 was connected on the lower right wall 25d of temporary fixed mechanism 25, arm 21 further moved to left from common enable possition O (with reference to Fig. 3).At this moment, the imaginary axis at the center by force application mechanism 23 is positioned at the left of the gyroaxis 21a of arm 21, so the active force of force application mechanism 23 acts on respect to arm 21, and it is turned round to the left.Again, under the state that the bend 27a of leaf spring 27 breaks away from from the holding section 26a of arm 21, leaf spring 27 is connected on the snap-latch piece 26.
At this, under the situation of active force greater than the active force of force application mechanism 23 with respect to the arm 21 of leaf spring 27, the active force of leaf spring 27 by with the position relation of above-mentioned snap-latch piece 26 to the right-hand effect of diagram.Therefore, represent that not under the situation of butt, form the state that arm 21 turns back to common enable possition O in arm 21 and temporary fixed mechanism 25, the bend 27a of leaf spring 27 engages with the holding section 26a of arm 21 as Fig. 3.At this moment, the fixed part 21b of arm 21 moves along the importing inclined-plane 25e of temporary fixed mechanism 25 as shown in phantom in Figure 9, and arm 21 turns back to enable possition O from the state that exceeds to illustrated left.
In addition, with above-mentioned opposite, at the active force of force application mechanism 23 during greater than the active force of leaf spring 27, though the bend 27a of leaf spring 27 is keeping the state that breaks away from that engages with the holding section 26a of arm 21, even but under this state, force application mechanism 23 also can continue the application of force towards illustrated left with arm 21, and is also without hindrance in the practicality.
The present invention is not limited to this routine form, can carry out various changes and enforcement.
In this example,, temporary fixed mechanism 25 is set on doorframe 12 on door body 11, also can in contrast temporary fixed mechanism 25 be set on door body 11, shutoff device body 2a is set at doorframe 12 though shutoff device body 2a is set.
Again, various changes, setting can according to circumstances be carried out in the fastening position and the enable possition with respect to doorframe 12 of door body 11.Thus, when closing, also can make a body 11 unlike shown in Figure 7, be in full-shut position, close under the state of predetermined gap but can be set at keeping.
Again, door body 11 can have pulley in the bottom, also can have pulley on top, forms the form by this pulley suspension door body 11.
In addition, when this shutoff device 2 is installed with respect to door body 11, especially under the occasion of door body 11 grades that are applicable to the vertical hinged door form, imbed shutoff device body 2a in door body 11 more at need, be not limited to as this example shutoff device body 2a imbedded the structure in the body 11, also can be installed on the surface of a body 11.Therefore, close the common door body 11 of device 2, transform, also this shutoff device 2 can be installed easily, application door closure device widely is provided by installing again for nothing.
