In addition, the above-mentioned auxiliary body that closes is installed in these slide rails.Fig. 3 and Fig. 4 represent to close an example of auxiliary body.This closes auxiliary body 6 by constituting with lower member: the slide block 61 that is located at guiding groove 60 on the outer rail 40 of fixed frame 2 sides, moves along this guiding groove 60, to this slide block 61 often to the spring 62 of an end reinforcing of above-mentioned guiding groove 60 be located on the interior rail of drawer 3 sides and the drive pin 63 that engages with above-mentioned slide block 61.
Above-mentioned guiding groove 60 forms slit-like, by constituting along the 60a of the portion of sliding of the moving direction of drawer relative fixed framework and the circular-arc fastener 60b that is arranged on this end that slides the 60a of portion continuously.This fastener 60b slides the end that the 60a of portion is located at the open direction of drawer 3 relatively.In addition, on above-mentioned slide block 61, be provided with a pair of foot 61a, the 61b chimeric, under the state that the 61a of these foots, 61b is entrenched in the guiding groove 60, can move freely along this guiding groove 60 with above-mentioned guiding groove 60.In addition, above-mentioned spring 62 one ends are attached on the slide block 61, in addition, the other end than above-mentioned end of sliding the 60a of portion also to the fixed-site of takeing in the direction displacement of drawer 3 on outer rail 40.Therefore, on slide block 61, act on the active force of taking in direction (Fig. 3 paper left) often towards drawer 3.But because at the end of fastener 60b, the action direction of guiding groove 60 and active force is quadrature roughly, so, as shown in Figure 3, when a 61b of foot of slide block 61 is positioned at fastener 60b terminal, can resists above-mentioned active force and make slide block 61 terminate in fastener 60b.
In addition, incision is provided with the slot 64 can put into above-mentioned drive pin 63 on above-mentioned slide block 61, constitutes, and when making in during relative outer rail 40 advance and retreat of rail, this drive pin 63 enters in the slot 64 of slide block 61 or disengaging slot 64.The arrow A direction is the direction of taking in of drawer 3 relative fixed frameworks 2 in Fig. 3 and Fig. 4, and the left end of guiding groove 60 is with that drawer 3 is put into the closed position of taking in fixed frame 2 fully is corresponding.Make drawer 3 from the release position when move the closed position, the drive pin 63 that is located at drawer 3 sides moves to the A direction with interior rail, as shown in Figure 3, enters in the slot 64 of slide block 61 of the fastener 60b that is set in guiding groove 60.Drive pin 63 is kept intact when the A direction moves, and the fastener 60b from guiding groove 60 breaks away from by the slide block 61 of this drive pin 63 pushings, and as shown in Figure 4, the active force that slide block 61 will be used spring 62 makes and slides the 60a of portion and move to the end of opposition side.At this moment, to slide block 61 its posture change that the portion 60a of sliding moves, become the state that drive pin 63 is surrounded by slot 64 from fastener 60b, drive pin 63 will move sliding on the 60a of portion with slide block 61.That is, will act on the active force of spring 62 by slide block 60a and drive pin 63 on drawer 3, drawer is set for and is automatically utilized this active force towards the closed position.
In addition, when pulling out drawer 3 from fixed frame 2 when being set in the release position, active force that must antagonistic spring 62, slide block 61 is set among the fastener 60b of guiding groove 60.Slide block 61 from the 60a of the portion of sliding of guiding groove 60 when fastener 60b moves, its posture change, in the moment of the end that arrives fastener 60b, drive pin 63 breaks away from from the slot 64 of slide block 61.Thus, as shown in Figure 3, the active force of slide block 61 antagonistic springs 62 is set on the fastener 60b.That is, when fixed frame 2 was pulled out drawer 3, above-mentioned slide block 61 was set in position shown in Figure 3, and when entering in the fixed frame 2, the setting state that engages with drive pin 63 at above-mentioned slide block 61 is in position shown in Figure 4.
Like this, utilize above-mentionedly when closing auxiliary body 6, before just drawer 3 being pushed fixed frame 2 fully, the active force of spring 62 acts on the drawer 3, so the not first reinforcing of user also can automatically be pushed into the closed position to this drawer 3.In addition, because the mode effect of above-mentioned active force so that drawer 3 is maintained in its closed position, so for example also can prevent because the unfavorable condition that earthquake etc. meet accident drawer 3 is opened.The active force of above-mentioned spring 62 is strong more, and these effects are remarkable more.
In contrast, with drawer 3 when fixed frame 2 is pulled out, active force that must antagonistic spring 62 is pulled out, the strong more then open drawer 3 of the active force of spring 62 needs big power more, has the tendency of ease of use variation.Therefore, open auxiliary body 5 is set in drawer shown in Figure 1, constitutes at least drawer is released the position of removing the active force of the spring 62 of closing auxiliary body 6 fully from fixed frame.
As shown in Figures 1 and 2, the inboard of the backplate 20 of fixed frame 2 is fixed in this opening auxiliary body 5, the space between the backplate 30 of the backplate 20 of fixed frame 2 and drawer 3.This opening auxiliary body 5 be bearing on the fixed frame 2 by an end by turning cylinder 50 and the other end by with the actuation arm 51 of backplate 30 butts of drawer 3 with follow the operation of firing switch 52 that the driving mechanism 53 of above-mentioned actuation arm 51 rotations is constituted.
Above-mentioned actuation arm 51 is arranged to and can be the center rotation by turning cylinder 50, usually such as using among Fig. 1 shown in the solid line, backplate 20 keeping parallelisms with fixed frame 2, but when the time from firing switch 52 input connection signals, be rotated into the position of in Fig. 1, representing, constitute backplate 30 with its terminal pushing drawer 3 with chain-dotted line.The moving runner 51a of rubber system is set at the end of above-mentioned actuation arm 51, so that the pushing of backplate 30 can be carried out smoothly, during actuation arm 51 rotations, this moving runner 51a contacts with the backplate 30 of drawer 3, and limit pushing drawer 3 is rotated on the plate 30 overleaf in moving runner 51a limit.
Fig. 7 is the enlarged drawing of the above-mentioned driving mechanism details of expression.As shown in the drawing, above-mentioned driving mechanism 53 is by motor 54, constitute the slow down decelerator 55 of the turning cylinder 50 that passes to actuation arm 51 and the torque limiter 56 that is installed between these motors 54 and the decelerator 55 of the rotation of this motor 54.In addition, though not expression in Fig. 7 is connected with the control part 57 of controlling its action on said motor 54.This control part 57 generates the drive control signal of said motor according to the information of being sent here by above-mentioned firing switch 52 grades, the rotatablely moving of control action arm.In addition, the Reference numeral 58 among Fig. 1 and Fig. 2 is the mains cords that are used for to control part 57 power supplies.
Above-mentioned firing switch 52 is installed on the handle 31 of drawer 3, no matter this handle 31 is moved to the front, or pushes the surface of handle 31 gently, and under any circumstance firing switch 52 all can send connection signal.Owing to like this firing switch 52 is installed on the handle 31 of drawer 3, has improved the operability of this firing switch 52.But, because above-mentioned actuation arm 51 and driving mechanism 53 carry on fixed frame 2, connecting holding wire so must between drawer 3 and fixed frame 2, draw, generation can not be extracted drawer 3 troubles such as grade out from fixed frame 2.Therefore, in the drawer of this embodiment, the fixing light-emitting component 32 that is connected with firing switch 52 on drawer 3, on fixed frame 2, be provided with in addition with above-mentioned light-emitting component 32 in opposite directions and the photo detector 33 that is connected with above-mentioned control part 57, can pass to above-mentioned driving mechanism 53 to the connection signal of firing switch 52 optically.
Be located at the state of closed position, promptly be housed in fully under the state in the fixed frame 2 at drawer 3, when the user pushed firing switch 52, the connection signal of firing switch 52 passed to control part 57 by light-emitting component 32 and photo detector 33.When control part 57 is imported the connection signal of firing switcies 52, generate the drive control signal of motor 54, and it is sent to motor 54.Thus, motor 54 begins to rotate, and makes actuation arm 51 rotations by this rotation.Actuation arm 51 pushings of rotation are set in the backplate 30 of the drawer 3 of closed position, resist above-mentioned active force of closing auxiliary body 6, bring into play the power of the direction that drawer 3 is opened.Thus, even the user is being provided with under the situation of closing auxiliary body 6, also can open drawer 3 like a cork.
In addition, owing to use the actuation arm 51 pushing drawers 3 of rotation, with the situation of the piston rod that uses advance and retreat etc. relatively, can constitute open auxiliary body 5 compactly, even also this opening auxiliary body 5 can be set easily in the small space between the backplate 30 of the backplate 20 of fixed frame 2 and drawer 3.
On above-mentioned driving mechanism 53, be provided with the position sensor 34 whether detection effect arm 51 turns to predetermined angular, if the output signal of this position sensor 34 counter-rotating, then above-mentioned control part 57 is ended the rotation of motor 54 immediately, make this motor 54 counter-rotatings simultaneously, make actuation arm 51 turn back to primary position, be the position shown in the solid line among Fig. 1.Therefore, when open drawer 3 then was pushed into fixed frame 2, actuation arm 51 had turned back to primary position, did not hinder actuation arm 51 moving to the closed position of drawer 3.
Corresponding to the distance of the active force effect of above-mentioned spring 62 of closing auxiliary body 6, be the stroke distances of slide block 61 and the length of actuation arm 51, the rotational angle of decisive action arm 51.This is because as long as drawer 3 is pushed the amount of the stroke distances of slide block 61 at least, and drawer 3 just can be from the active force release down of spring 62, makes drawer 3 mobile gently by the effect of above-mentioned slide rail 4a, 4b.
In addition, exist in the place ahead of drawer 3 under the situation of barrier, if faulty operation firing switch 52, excessive rotating torque affacts on the actuation arm 51 from motor 54, might cause the breakage of gear or the losing of actuation arm 51 of decelerator 55.Above-mentioned torque limiter 56 is used to avoid this this state of affairs, is installed between motor 54 and the decelerator 55, does not constitute the above rotating torque of setting value is passed to decelerator 55 from motor 54.In addition, owing to the state of affairs that barrier is not opened, until what time motor 54 all is rotated further, in above-mentioned control part 57, be provided with timer conter for fear of drawer 3.If begin rotation motor 54 to the direction of opening drawer 3, the value of the above-mentioned timer conter of control part 57 counting reaches moment of setting in this value, and is irrelevant with the counter-rotating of the output signal of above-mentioned position sensor 34, end the rotation of motor 54, make actuation arm 51 turn back to primary position.Thus, can in contingency, protect open auxiliary body 5.
Above-mentioned firing switch 52 also can carry on drawer 3.Fig. 8 to Fig. 9 represents other form of firing switch.
In these figure, the limit switch 35 that whether detection drawer 3 is set in the closed position uses as firing switch.This limit switch 35 is fixed on the backplate 20 of fixed frame 2, and drawer 3 is being set under the state of closed position, pushes this limit switch 35.Therefore, as shown in Figure 9, as the user hand is placed on the handle 31 of drawer 3, when fixed frame 2 is pulled out drawer 3 slightly, removes the pushing state of limit switch 35 constantly, to the output signal of control part 57 input counter-rotatings at this.As trigger, control part 57 rotates motor 54 it, and as shown in figure 10, actuation arm 51 rotations are to opening direction pushing drawer 3.
In such structure, the user need pull out drawer 3 slightly with the power of self at first, but after the counter-rotating of the output signal of limit switch 35, because actuation arm 51 pushes drawer 3 from behind, so, can resist the active force of closing auxiliary body 6, easily set drawer 3 from the closed position to the release position.
In addition, in the embodiment that has illustrated with figure, the direction of rotation of above-mentioned actuation arm 51 is set above-below direction for, but this direction of rotation also can be a horizontal direction.Under the situation of the thin thickness of drawer 3, consistent by the direction of rotation that makes actuation arm 51 with horizontal direction, can seek to save the space that is provided with of open auxiliary body 5.In the case, by using bevel gear at the motor 54 from driving mechanism 53 to the power transfer path of actuation arm 51, the turning cylinder of motor 54 also can be consistent with horizontal direction, can further seek to save the space.

The upright above-mentioned relatively turning cylinder 71 of double-screw bolt 74 that is located on the above-mentioned actuation arm 72 is positioned at the opposition side of the terminal part 72a of this actuation arm 72, the pulling force of helical spring 75 puts on this double-screw bolt, the rotation of the arrow B direction that the terminal part 72a generation of actuation arm 72 is represented in Figure 12.In addition, the Reference numeral 70a among Figure 11 and Figure 12 is the retainer that limits the rotation terminal of actuation arm 72, is ended by this retainer 70a card by the actuation arm 72 that the active force of helical spring 75 rotates.
In addition, above-mentioned driving mechanism 76 is located at the banking pin 76a of double-screw bolt 74 dorsal parts and is blocked the restricted arm 78 of ending above-mentioned banking pin 76a simultaneously by motor 77 rotating drive by above-mentioned actuation arm neutrality and constitutes.Said motor 77 is rotated a circle when operation firing switch 52, above-mentioned restricted arm 78 is broken away from from restriction site shown in Figure 12, makes this restricted arm 78 rotate 360 °, is set in restriction site once more.
Under the state that motor 77 stops, above-mentioned restricted arm 78 is set in restriction site shown in Figure 12.Restricted arm 78 contacts with the banking pin 76a of actuation arm 72 at this restriction site, and card ends the spinning movement of this actuation arm 72, makes it remain on above-mentioned original position.Restricted arm 78 its sides that are set in above-mentioned restriction site do not join with banking pin 76a, and terminal bight and the outer peripheral face of banking pin 76a join.Therefore, when making restricted arm 78 begin to rotate by motor 77, above-mentioned banking pin 76a is open to the direction of the center of rotation of leaving restricted arm 78, and the card of the banking pin 76a that is produced by above-mentioned restricted arm 78 ends state and is disengaged.
Above-mentioned actuation arm 72 has the pushing curved surface 72b that the backplate 30 with drawer 3 joins.This pushing curved surface 72b is along with drawer 3 is released in actuation arm 72 rotations from the closed position, and backplate 30 limit rolling edge joints touch relatively.Closed position at drawer shown in Figure 12 3, above-mentioned contact area be positioned at the pivot that becomes actuation arm 72 turning cylinder 71 near, but along with actuation arm 72 is released drawer 3 to the rotation of arrow B direction from fixed frame 2, above-mentioned contact area becomes the state approaching with the terminal part 72a of actuation arm 72.
The open auxiliary body 7 that Figure 13 A to Figure 13 E represents this second embodiment when fixed frame 2 is released drawers 3 actuation arm 72 and a series of actions of driving mechanism 76.
When from this state of operation firing switch 52, motor 77 begins to rotate, and as shown in FIG. 13A, the restricted arm 78 that is connected with this motor 77 becomes the state of pushing banking pin 76a to the outside of radial direction open, around the turning cylinder rotation of motor 77.Its result, banking pin 76a cross over the end of restricted arm 78, and the card of the banking pin 76a that is produced by restricted arm 78 ends state and is disengaged.
When the card of pin 76a of lifting restrictions ended state, shown in Figure 13 B, the actuation arm 72 that is subjected to the active force of helical spring 75 began rotation around turning cylinder 71, along with this spinning movement, and the backplate 30 of the pushing curved surface 72b of actuation arm 72 pushing drawer 3.Thus, the auxiliary force of pulling out the direction of drawer 3 from fixed frame 2 will act on this drawer 3.
As shown in FIG. 13A, in the stage that the card of the pin 76a that lifts restrictions ends state, the contact area 8 of the pushing curved surface 72b of actuation arm 72 and the backplate 30 of drawer 3 is positioned near the turning cylinder 71 of actuation arm 72.But when actuation arm 72 began to rotate, the backplate 30 limit rolling edge joints of the relative drawer 3 of above-mentioned pushing curved surface 72b touched, and shown in Figure 13 B, above-mentioned contact area 8 will move to the terminal part 72a of actuation arm 72.
Pulling out from fixed frame 2 under the situation of the drawer 3 that is still in the closed position, this drawer 3 begin to start the time need big power, but, can apply big pushing force by 72 pairs of these drawers 3 of actuation arm when then drawer 3 begins to start as adopting above-mentioned contact area 8 from the structure that near the 72a of the terminad portion turning cylinder 71 of actuation arm 72 slowly move.In addition, along with actuation arm 72 rotations, above-mentioned contact area 8 is near the terminal part 72a of actuation arm 72, and the pushing force that actuation arm 72 imposes on drawer 3 reduces, and can apply pushing force to drawer in the distance corresponding with the length of actuation arm 72.
In addition, the structure of the pushing curved surface 72a of such actuation arm 72 is not limited to the actuation arm 72 of this second embodiment, also goes for the actuation arm 51 of first embodiment.
Like this, shown in Figure 13 C, the actuation arm 72 that begins to rotate the pushing drawer is under the roughly consistent state of its length direction and the moving direction of drawer 3, by above-mentioned retainer 70a card only.At this moment, the contact area 8 of the backplate 30 of pushing curved surface 72b and drawer 3 is positioned at the terminal part 72a of actuation arm 72.In addition, at this moment drawer 3 by the active force of the spring 62 of closing auxiliary body 6 by opening, the user can easily pull out drawer 3 to the release position.
During actuation arm 72 rotations, above-mentioned restricted arm 78 is rotated further like this.Restricted arm 78 began rotation originally, just pushed the upright banking pin 76a that is located at actuation arm 72 laterally open from the rotating range of this restricted arm 78, when the active force of actuation arm 72 usefulness helical springs 75 rotates, was positioned at the rotating range of above-mentioned restricted arm 78 once more.Therefore, shown in Figure 13 D, continue the restricted arm 78 of rotation and collide with banking pin 76a once more, push this banking pin 76a simultaneously, the active force of opposing helical spring 75 is pushed actuation arm 72 to original position.
Said motor 77 also is rotated further after above-mentioned restricted arm 78 is collided with banking pin 76a, stops behind rotation one circle, and above-mentioned restricted arm 78 is set in initial restriction site.That is, restricted arm 78 is set in position shown in Figure 12, and actuation arm 72 will turn back to original position thereupon.At this moment, drawer 3 is in the state that is drawn out to the release position from the closed position, and the backplate 30 of drawer 3 is in the state that leaves with actuation arm 72.Therefore, along with the user pushes drawer 3 fixed frame 2, closes auxiliary body's 6 actions, when this drawer 3 arrives the closed position once more, the pushing curved surface 72b of actuation arm 72 and the backplate 30 of drawer 3 will contact under state shown in Figure 12.
In the open auxiliary body 7 shown in this second embodiment, along with ending state, the card of the banking pin 76a that is produced by restricted arm 78 is disengaged, because the active force of actuation arm 72 usefulness helical springs 75 applies pushing force to drawer 3, so there are not any engaging in restricted arm 78 and banking pin 76a in actuation arm 72 these pushing force processes of performance, because having hindered drawer 3 to the moving of release position, barrier on the motor 77 of rotating drive restricted arm 78, can not act on any load even suppose yet.Therefore, need not as the open auxiliary body 5 of first embodiment that the rotation of motor 54 is passed to actuation arm 51 mounting torque limiter 56 between actuation arm 51 and motor 54, also do not need the complexity control of motor 54 in addition.Therefore, the open auxiliary body 7 of second embodiment is can be than the open auxiliary body 5 of first embodiment compact and constitute at an easy rate.
