Cylinder part holding member 6 is fixed on the leading section of cover 10 receiving grooves.On cylinder part holding member 6, to rear end face, form and come and go the cutting shortcoming part 15 that moving direction extends along the front and back of bar H from the front end face of cylinder part holding member 6.
At the leading section of cover 10 receiving grooves, rear end face one side at cylinder part holding member 6 disposes magnet adsorption element 12, and magnet adsorption element 12 is fixed on the cylinder part holding member 6.
Between fastening position and open position, come and go in the moving process at bar H, in the motion track of the cover 10 of bar H upper end, the precalculated position that arrives the tight front of fastening position at bar H disposes holding member 7, keeps removing parts 7 and is fixed on the supporter W.In this embodiment, keep removing parts 7 and constitute the supporter parts.
Keep removing parts 7 comprises: below the supporter W relative with the upper surface (that is: the upper surface of cover 10) of bar H, and near fixing elongated base plate 20 its front end; Magnet adsorption element 13 is removed in the maintenance outstanding from the above-mentioned precalculated position of elongated base plate 20 to above-mentioned motion track.Keep to remove magnet adsorption element 13, before the bar H that moves to fastening position arrived above-mentioned precalculated position, the cutting shortcoming part 15 of the cylinder part holding member 6 of the leading section of the cover 10 by bar H was not connected with cylinder part holding member 6.Yet, keep to remove magnet adsorption element 13, when the bar H one that moves to fastening position arrives above-mentioned precalculated position, just be connected with the magnet 11 that bar H covers the cylinder 1 front end butt parts 5 in 10 receiving grooves, adsorbed by magnet 11.
As mentioned above, constitute the related bar closing buffer of the present invention's the 1st embodiment, when bar H is configured in fastening position with respect to supporter W, the front end face of bar H is connected with the door one side M of company of supporter W, the magnet 11 that bar H covers the cylinder 1 front end butt parts 5 in 10 receiving grooves is connected with the maintenance releasing magnet adsorption element 13 that parts 7 are removed in the maintenance of supporter W, by the magnetic force of magnet 11, magnet 11 is held and removes 13 absorption of magnet adsorption element, keeps.At this moment, bar H covers the magnet 11 of the front end butt parts 5 of the cylinder 1 in 10 receiving grooves, separates backward from the magnet adsorption element 12 of the rear end face that covers 10 leading section cylinder part holding members 6.And this moment, to close spring 4 and produce tractive force, this tractive force acts between the lid 14 and the spring support member 8 on the axle 3 of cylinder 1.
Be fixed on the magnet 11 of the butt parts 5 of the cylinder 1 that covers on 14 by cylinder 1, the maintenance of supported body W is removed the maintenance of parts 7 and is removed 13 absorption of magnet adsorption element, keeps, because the spring support member 8 of axle on 3 is by the axle fixed part and cover 10 and fixed by bar H, so the tractive force of closing spring 4 to the fastening position application of force, is maintained in its closed position bar H to bar H.
If the above-mentioned tractive force of closing spring 4 of opposing, bar H is moved to open position from fastening position, cylinder part U will supported body W the maintenance maintenance of removing parts 7 remove 13 absorption of magnet adsorption element, keep, with bar H not in the process that fastening position moves, be fixed on axle on the bar H 3 with the cylinder 1 of bar H, carry out relativity to open position and move with respect to cylinder part U.Therebetween, with respect to the lid 4 of cylinder part U, the spring support member 8 on the axle 3 also carries out relativity to the release position and moves.As a result, two ends are separately fixed at the lid 4 of cylinder part U and the spring 4 of closing on the axle 3 upper spring support components 8 is pulled, and close the tractive force increase that spring 4 produces.
Bar H from fastening position when open position moves to above-mentioned precalculated position, the magnet adsorption element 12 of the cylinder part holding member 6 of the leading section of the cover 10 of the bar H that moves to open position, be connected on the magnet 11 of butt parts 5 of cylinder part U, by the magnetic force of magnet 11, the butt parts 5 of cylinder part U are by 12 absorption of magnet adsorption element, the maintenance of cylinder part holding member 6.As a result, cylinder part U is pressed towards open position owing to the cylinder part holding member 6 of the leading section of the cover 10 of the bar H that moves to open position.
If bar H continues to move to open position from above-mentioned precalculated position, the magnet 11 of the butt parts 5 of cylinder part U acts on supporter W and keeps the magnetic force of the maintenance releasing magnet adsorption element 13 of releasing parts 7 to keep and will be disengaged, in this process, magnet adsorption element 12 with respect to the cylinder part holding member 6 of the leading section of the cover 10 of bar H, the magnet 11 of the butt parts 5 of cylinder part U continues by magnet adsorption element 12 absorption of cylinder part holding member 6, keeps owing to its magnetic force.Simultaneously, close spring 4 and be held in above-mentioned traction state, close increase that spring 4 produces the tractive force savings close in the spring 4 trailed.
That is: move to the process in above-mentioned precalculated position to the open position direction from fastening position at bar H, need to result from the resistance of closing the tractive force that spring 4 increased and load on bar H towards the release position, also can produce the tractive force that has increased closing spring 4.In said process, close increase that spring 4 produces the tractive force dynamics, move along the length direction of axle 3 permanent position that makes the spring support member 8 on the axle 3, and can regulate, the inventor thinks that this is readily appreciated that for personage of the same trade or business.
And, make bar H from above-mentioned precalculated position to the process that open position is moved further, be accumulated in remain above-mentioned traction state close increase in the spring 4 tractive force, for bar H moving to open position without any influence.This situation mean bar H from above-mentioned precalculated position to the process that open position is moved further, except producing between bar H and the supporter W the friction opposing, can not exert an influence for moving of bar H.Its result, bar H is moved to the process in above-mentioned precalculated position to the open position direction from fastening position, with need compare loading on the bar H than being applied to the bigger situation of the application of force of closing spring 4 in the above-mentioned friction opposing towards the power of open position, make bar H from above-mentioned precalculated position to the process that open position is moved further, the power that need load on bar H is much smaller.
And then between above-mentioned precalculated position and open position, bar H is if not in order to move the loading of needed little power to bar H to open position, will make bar H be parked in the optional position.And the effects such as external force even without special stop position holding member, realization stop position keep also can make bar H stop at above-mentioned optional position.Certainly, above-mentioned optional position comprises open position.
Bar H is moved to the process in precalculated position to the open position direction from fastening position, and then the piston 2 of the leading section of axle 3 rearward carry out relativity with respect to cylinder 1 and move in the inner space of cylinder 1.Be accompanied by this moving, produce air resistance at piston 2.But, owing to above-mentioned the moving of bar H is the increasing traction of closing spring 4 to be put up a resistance carry out, so the translational speed of the bar H in the above-mentioned moving process is slow.Therefore, above-mentioned air resistance is compared much smaller with the increasing traction of closing spring 4, and the above-mentioned mobile of bar H exerted an influence hardly.
Secondly, the bar H that is configured in above-mentioned optional position like this is in being moved to the process of fastening position, and the action of closing buffer of the related bar of above-mentioned the 1st embodiment can be elaborated with reference to (A) to (D) of Fig. 6.
For the bar H that moves to fastening position from above-mentioned optional position, till the precalculated position that arrives the tight front of fastening position, between bar H and supporter W, produce the friction opposing, can not exert an influence to the mobile of bar H.In this process, shown in Fig. 6 (A) and Fig. 7 (A), in the receiving groove of cover 10, the magnet 11 of the butt parts 5 of the cylinder 1 of cylinder part U is adsorbed, remains on the magnet adsorption element 12 of the cylinder part holding member 6 of cover 10 leading sections, its result, as mentioned above, will accumulate the tractive force that has increased closing spring 4.
Before the bar H that fastening position moves arrived above-mentioned precalculated position, the maintenance of supporter W was removed the maintenance of parts 7 and is removed magnet adsorption element 13, the cutting shortcoming part 15 of the cylinder part holding member 6 of the cover 10 of access door sash H.
Bar H shown in Fig. 6 (B) and Fig. 7 (B), keeps removing magnet adsorption element 13 and is connected with the magnet 11 of the butt parts 15 of cylinder part U when arriving above-mentioned precalculated position, and the magnetic force by magnet 11 is attracted to magnet 11, maintenance butt parts 5.
Remain on the cylinder part U that keeps removing magnet adsorption element 13, in the mobile process that is stopped of fastening position, if bar H further moves to fastening position from above-mentioned precalculated position, towards the magnet adsorption element 12 of the leading section cylinder part holding member 6 of the cover 10 of the bar H of fastening position, for the absorption of the magnet 11 of the butt parts 5 of cylinder part U and keep and to be disengaged.Then, for the bar H that moves to fastening position, for it is moved to fastening position from above-mentioned optional position, comprise the external force that is carried on the bar H, the increase of in closing spring 4, accumulating tractive force be loaded on the bar H of fastening position.
Like this, for from above-mentioned precalculated position further to the bar H of fastening position, the piston 2 of the leading section of axle 3, shown in Fig. 6 (C) and Fig. 7 (C), forwards move inner space at the cylinder 1 of cylinder part U, and in this process, compressed air between the butt parts 5 of cylinder 1 front end and piston 2.Like this, compressed air is discharged to space outerpace gradually by the above-mentioned steam vent that forms at butt parts 5.
Its result, although be loaded in bar H as described above towards fastening position towards the external force of fastening position and the tractive force of closing spring 4, but, because the strength alleviating function that above-mentioned compressed air and above-mentioned steam vent produce, prevented that bar from moving towards fastening position rapidly, thus with velocity surface slowly to fastening position.
The inventor thinks, regulates parts as aperture area, the radial direction of steam vent use can be free to advance or retreat screw, the degree of the alleviating function performance of above-mentioned power can be regulated arbitrarily, this is readily appreciated that for the industry personage.
Like this, can prevent conscientiously that bar H from producing when arriving fastening position rapidly from rebound phenomenon and send very big impact sound of fastening position.
And, bar H from above-mentioned precalculated position towards fastening position, till arriving fastening position since be accumulated in the increase of closing in the spring 4 tractive force, bar can automatically be moved to fastening position, and its translational speed is a slow speed as described above.
So shown in Fig. 6 (D) and Fig. 7 (D), the front end face of bar H makes bar H stop at fastening position by connecting with the one side M that is connected door of supporter W.Owing to stop at the bar H of fastening position, still be closed spring 4 as mentioned above and load tractive force, so bar H is securely held in fastening position.
In addition, (D) referring to figs. 1 through Fig. 7, the bar closing buffer that the 1st embodiment of the invention described above relates to, it constitutes: the magnet adsorption element 12 of the cylinder part holding member 6 of the magnet 11 of cylinder part U and cover 10 leading sections constitutes the cylinder part holding member, this cylinder part holding member is resisted the application of force of closing spring 4 at bar H, the state that makes cylinder part U keep bar H to move towards the fastening position direction with respect to axle 3.
Also have, this the 1st embodiment, the maintenance releasing magnet adsorption element 13 that keeps removing parts 7 is set at supporter W place, and bar H is in the process that moves to fastening position, precalculated position in the tight front of fastening position, in the above-mentioned maintenance of removing cylinder part holding member countercylinder 1, keep cylinder part U, then, by closing the application of force of spring 4, bar H is moved to fastening position, arrive fastening position, constitute maintenance thus and remove parts.
