Below, with reference to Fig. 4～Fig. 6, the method that this door closer-holder 1 moves is described.

At first, the summary of this door closer-holder 1 action is described with reference to Fig. 6.

At the apparatus main body 6 of Fig. 1 be directed under the state that parts 7 engages when door A is opened, apparatus main body 6 close the angle position that an arm 20 remains on the regulation dwell angle that adaptation can engage with the sliding part 31 that is directed to parts 7.At the handle of controlling an A from this state at closing time, reach the closed action of door closer-holder 1 at door A before, when the position (being the angle position of 15 ° of left and right on this figure in the present embodiment) arrived shown in Fig. 6 (A), sliding part 31 starts to engage with the gathering sill 27c that closes an arm 20, afterwards, with the relatively moving of gathering sill 27c along closing an arm 20 of sliding part 31, synchronize, even door A gives to being forced to property for example large closing speed as described later, also can make it slow down and be closed lightly, become the state of Fig. 6 (B).On the contrary, when the state of Fig. 6 (A) is opened A, as long as control the handle of an A, power is put on to this handle after pulling out latch at the state from Fig. 6 (B).Now, as mentioned above, use device main body 6 and the power that is directed to the installation site of parts 7 and need not increases on the handle that puts on an A just can be opened an A, in addition, as described later, the effect that can close the rotation of an arm 20 by the promotion of damper 19 alleviates the power on the handle that puts on an A.

Below, the structure of carrying out the action shown in above-mentioned Fig. 6 of door closer-holder 1 is described with reference to Fig. 4 and Fig. 5.Wherein, not shown door A and be directed to parts 7 in Fig. 4 and Fig. 5.

Fig. 4 (A) is identical with Fig. 6 (A), means the state before the closed action of door closer-holder 1, indication device main body 6 close the state that an arm 20 remains on the angle position that adapts to the regulation dwell angle that can engage with the sliding part 31 that is directed to parts 7.Now, because rotatable lamella 14 makes the little tumbler 23 of this rotatable lamella 14 connect with this slide block 15 in the inclined plane of slide block 15 15a2 side, accept the moment of dextrorotation veer among Fig. 4 (A) from spring 16 via this slide block 15, on the other hand, make the second arm 14b of this rotatable lamella 14 be connected to the front end face 12b1 of left fixed block 12, and accept to be rotated counterclockwise the moment of direction from this left fixed block 12, therefore, remain on by closing an arm 20 angle position that the dwell angle with afore mentioned rules adapts.On the other hand, in the present embodiment, damper 19 is set as exerting all one's strength and not acting on its second arm 14b via slide block 18.

And, for making door closer-holder 1, the state from Fig. 4 (A) starts to close an action, when opposite house A applies power, the little tumbler 23 that rotatable lamella 14 becomes this rotatable lamella 14 is crossed the summit 15a1 of slide block 15 state connected at inclined plane 15a3 side and this slide block 15, that is, become the state of Fig. 4 (B).When this state, the elastic reactance of rotatable lamella 14 by the spring 16 given via slide block 15 (can suitably regulate by adjusting device 17 by this elastic reactance.), accept to be rotated counterclockwise the moment (direction of arrow A1 on this figure) of direction in Fig. 4 (B), therefore, close the moment (direction of arrow A2 on this figure) that an arm 20 also accepts to be rotated counterclockwise direction, thus, door A is further closed automatically.Now, because making the side 18a of the second slide block 18, damper 19 is connected to the second arm 14b of rotatable lamella 14, and give rotatable lamella 14 via the second slide block 18 by the moment of dextrorotation veer, therefore, can suppress rotatable lamella 14 and be rotated counterclockwise the rotating speed of direction and make its deceleration.But, when rotatable lamella 14 is rotated and is arrived the state of Fig. 5 (A), , reach while along with closing of door A, being arranged on the handle of this A that latch sinks to the moment of the pin hole that is arranged at munnion parts 3, until to the state of Fig. 5 (B), rotatable lamella 14 and the above-mentioned moment that similarly by the power that applies of spring 16, continues to accept to be rotated counterclockwise direction, thus, close an arm 20 and also receive the moment that is rotated counterclockwise direction, but, because the inclined plane 18a1 side of this slide block 18 is transferred at the butt object position of the slide block 18 of the second arm 14b with this rotatable lamella 14, therefore, resistance from damper 19 can be via 14 effects of 18 pairs of these rotatable lamellas of this slide block.Thus, in rotatable lamella 14, therefore, can guarantee that the latch of an A sinks to pin hole and obtains reliable closure state due to the moment loading that is rotated counterclockwise direction that only has spring 16.

When the state in Fig. 5 (B), as mentioned above, rotatable lamella 14 accepts to be rotated counterclockwise the moment of direction in Fig. 5 (B), on the other hand, the first arm 14a of this rotatable lamella 14 is connected to the inclined plane 12a1 of left fixed block 12, and accept moment and the balance of dextrorotation veer from this left fixed block 12, therefore, can keep the closed condition of an A.

While opening A the state of closing fully from door A at the state from Fig. 5 (B), pull out latch as long as control the handle of an A, and apply the power that applies (this applies power and can suitably regulate by adjusting device 17) that opposing is imparted to the spring 16 of rotatable lamella 14 via slide block 15 get final product on this handle.As mentioned above, in adopting apparatus main body 6 and being directed to this door closer-holder 1 of installation site of parts 7, compared with prior art can alleviate the power now applied, and, be connected to the second arm 14b of rotatable lamella 14 via slide block 18 due to damper 19, and in Fig. 5 (A), the moment of dextrorotation veer (direction of arrow B1 on this figure) is put on to this rotatable lamella 14, therefore, close the moment (direction of arrow B2 on this figure) that an arm 20 also is applied in the dextrorotation veer.Thus, because the mode of closing the rotation of an arm 20 dextrorotation veers with promotion works, thereby can further alleviate the power that puts on an A.

In addition, when the closing an arm 20 and be directed to the engaging of sliding part 31 of parts 7 of open the door action and the decontrol main body 6 of carrying out an A, close the angle position that an arm 20 remains on the dwell angle of the regulation that adaptation can engage with sliding part 31 certainly.

Below, with reference to Fig. 7, illustrate the angle position that remains on the dwell angle that is adapted to afore mentioned rules apparatus main body 6 close an arm, sometimes also former because of certain thereby change above-mentioned angle position, to making the method that an arm 20 resets to above-mentioned angle position of closing in this case, describe.

In this door closer-holder 1, even change above-mentioned angle position, as shown in Fig. 7 (A), also can make an A rotate to the direction (direction of the arrow indication on figure) of closing door, in other words, make to be directed to parts 7 approaching device main bodys 6 and make the sliding part 31 that is directed to parts 7 be connected to the inclined plane 27d that closes an arm 20, in addition, while making an A rotate to the direction of arrow under the butt state, as shown in Fig. 7 (B), above block part 30, the outstanding sliding part 31 of 30a accepts the power of self-closing door's arm 20, and the power that opposing is installed on the spring that is directed to parts 7 is depressed, the outstanding a great deal of be depressed of the end portion of this sliding part 31 30b below slider part 30.And, while under maintaining such butt state, making an A further continue to rotate to the direction of arrow, as shown in Fig. 7 (C), sliding part 31 in the level face is inserted into gathering sill 27c, becomes the state that an arm 20 and sliding part 31 fasten that closes from the inclined plane 27d that closes an arm 20.Thereupon, locating snap ring 32 is limited to the following 30b of slider part 30.

Like this, while opening again A after the state that sliding part 31 temporarily is sticked in to the gathering sill 27c that closes an arm 20, through the action of being opened the door of the state of above-mentioned Fig. 7 (C).And, after the engaging of an arm 20 and sliding part 31 is closed in releasing, close the angle position that an arm 20 remains on the dwell angle that is adapted to the regulation that can engage with sliding part 31, make to close an arm 20 and reset to above-mentioned angle position.

But, as above-mentioned embodiment, open the door A of use for the right side, to close via its erecting bed 28a the lower body 8b side that an arm 20 is installed on the outer frame body main body 8 of apparatus main body 6, even but for Zuo Kaiyong the door, this door closer-holder 1 also can come by following method corresponding, that is, the erecting bed 28a that closes an arm 20 via this closes by this upper plate body 8a side that arm 20 is installed on the outer frame body main body 8 of apparatus main body 6.Particularly, can come corresponding by following method, , closing on an arm 20, the chimeric axle 28a1 in the large footpath of erecting bed 28a is slowly inserted to the inserting hole 8a1 of outer frame body main body 8, the chimeric axle 28a2 of the path of erecting bed 28a is slowly inserted to the bearer ring 21b of internal frame body upper plate body 11, again the connection shaft 28a3 of erecting bed 28a is slowly inserted in the hole of square shape of little axial region 14c1 of axial region 14c of rotatable lamella 14, then, by erection bolt 29 is installed on to the chimeric axle 28a1 of erecting bed 28a from the upper bottom surface 27 side screw threads that close an arm 20, the screw hole of 28a2 and connection shaft 28a3.Therefore, no matter due to this door closer-holder 1 as R.H.flapped door with or but as L.H.flapped door use dual-purpose all, thereby using method when operation is set is good.
