Description
Technical field
The present invention relates to a kind of for opening and closing the servicing unit of door.
Background technology
Be known in principle multiple for opening and closing the servicing unit of door.These servicing units are for example called as door closer and are used to should be with the door of automatically assisting to opening and closing.These known door closers be conventionally fastened to the top portion section of door and by lever motion mechanism and doorframe in other words doorjamb be connected.Conventionally be furnished with servicing unit in this door closer inside, this servicing unit can opening with the spring force opposing door of resistance or raising.Be configured to such door and decontroled and pass through afterwards door closer in open position, can be described as automatically, again move back in fastening position by the spring force being loaded.For such embodiment, need very expensive, design very greatly and especially very heavy door closer and servicing unit, to also can make corresponding entrance gate and outlet portal motion.Also must carry out respective support to the affiliated power of closing in the housing of this servicing unit.
The difficulty that shortcoming in known servicing unit is embodiment aspect mechanical stability and required structure space.To the installation on doorjamb or door-plate, due to these, to require be to be difficult to realize to such servicing unit now.Master Cost and consequent cost are also relatively high, thus these door closers be not used in interior door.
Summary of the invention
Therefore, task of the present invention is to eliminate at least in part shortcoming described above.In addition, task of the present invention is also, in simple door, especially in the interior door of building, also provides assisting closing process or opening procedure in low cost and simple mode.
The servicing unit of the feature of above-mentioned task by having claim 1 solves.Other features of the present invention and details are drawn by dependent claims, manual and accompanying drawing.At this, obviously also can be in conjunction with the structural scheme of the present invention of pressing of dependent claims in conjunction with the described feature of servicing unit according to the present invention and details, and vice versa, thus open interrelated or can be interrelated all the time about various aspects of the present invention.
Servicing unit according to the present invention is used to open or close door, and this servicing unit has housing, in this housing, is furnished with auxiliary body.Be according to the remarkable part of servicing unit of the present invention, this auxiliary body has the supported power shaft of mode rotatablely moving between open position and fastening position.This power shaft is for absorbing the motion of door.In addition, be provided with chute guide portion with the supported guide sleeve of mode that can move along axis of movement.At this, have spring assembly, its along axis of movement with spring force bootload sleeve.In addition, power shaft has chute pin, and this chute pin is connected with the effect of chute guide portion.Be configured with chute guide portion, so that at least reduction or storage or secondary spring power in the open position of power shaft and/or fastening position.
Servicing unit according to the present invention is particularly constructed as follows, that is, make this servicing unit have very little structure space, and also can use less and correspondingly in light interior door.Especially optimize as follows the size of servicing unit, that is, can install or be integrated on door-plate or doorjamb.This especially realizes by the boring in door-plate.
Servicing unit is for opening procedure or the closing process of auxiliary door.Particularly the end region of this opening procedure or closing process is that the present invention pays close attention to.Therefore,, by servicing unit according to the present invention, the spring force acting in guide sleeve changes in opening procedure.Spring force reduces in the direction towards open position and/or in the direction towards fastening position.This means, if having for example in the closed position according to the door of servicing unit of the present invention in, user must overcome the spring force improving constantly so, to make door leave closed condition.If door is through idle running (Freilauf) regional movement to open position, spring force preferably again reduces in open position so.Opening aspect motion of door, this causes the spring-force driven dual that constantly reduces to door and door is moved in open position on one's own initiative.In other words, the spring force constantly reducing by door locked in corresponding end position, namely in open position and/or fastening position.
In view of the opening characteristic of this door, said system is guaranteed by the member according to the present invention of auxiliary body.Core of the present invention is associated with the translational motion of guide sleeve of rotatablely moving of power shaft.This association is connected to guarantee by the effect between chute pin and chute guide portion at power shaft.Correspondingly, power shaft is only supporting rotatably preferably, and guide sleeve only translation ground supporting substantially.The motor function being excluded is respectively for example by guaranteeing the positive guide of guide sleeve or power shaft.
If power shaft moves to fastening position from open position, so the relative motion of affiliated chute pin in chute guide portion carried out automatically.Because power shaft is fixed aspect translational motion, so in the chute guide portion of relative configurations, affiliated guide sleeve must be avoided the chute pin of rotation.This avoiding carried out in the translational motion along axis of movement, and this translational motion is associated with affiliated spring assembly and the corresponding spring force loading again.If for example guide sleeve loads with spring force from below, chute guide portion can be constructed as follows so, that is, in the time that power shaft rotates, guide sleeve overcomes spring force and pressed downwards.At least one position in two end positions or two end positions, the namely open position of power shaft and/or fastening position, be associated with portion's section of chute guide portion respectively, its with the minimum elasticity of spring assembly and therewith corresponding with reduce spring force be associated.Preferably on two ends of chute guide portion, be provided with corresponding structure, thus make spring force reduce be associated with open position and fastening position.
If in the fastening position of power shaft in being associated with the fastening position of door, so spring assembly be used for bootload sleeve spring force reduce.In order to cause door to be opened, power shaft must leave fastening position together with door.In the time that power shaft leaves fastening position, affiliated chute pin also automatically moves in chute guide portion, thereby is accompanied by the translational motion of guide sleeve from leaving of fastening position.This guide sleeve overcomes spring assembly translation moves, thereby this relative motion has improved spring force.In the time that motion finishes, namely, in the time that power shaft moves to open position, the orientation of chute guide portion on geometry changes again.In the time arriving open position, chute guide portion is moved away from spring assembly guide sleeve again the latest, and therefore spring force reduces.This also can be called as by retracting spring power locking or be locked in open position.
The above-mentioned mode of action is applied on door as follows.Door is locked in open position and/or fastening position by the spring force reducing.Each door wants the motion moving out from open position and/or make position must cause the spring force of servicing unit or auxiliary body inside to improve.The raising of this spring force must additionally be applied on door as power by opening wish.As long as the power on door of being applied to does not exceed the raising of the spring force of auxiliary body inside, door just remains in open position and/or fastening position so.The difference of the spring force loading in open position or fastening position and near the spring force these two positions can be called as the latching force for each end position of door or auxiliary body.
By the working method of the auxiliary body that elaborates, especially by associated with the translational motion of guide sleeve on the other hand of rotatablely moving of one side power shaft, can guarantee the special compact structure form of whole servicing unit above.Particularly each single member can interconnect and construct, thereby for example makes power shaft extend through the inside of guide sleeve.If spring assembly is for example configured to helical spring, it equally can be around power shaft so, from and further improved the compactedness of form of structure.In a word, servicing unit can realize especially compactness and light form of structure by design scheme of the present invention, it especially also can be used in the lighter interior door with the corresponding very little power demand to auxiliary body.This form of structure of dwindling can also be implemented to integrated in door-plate or doorjamb.
The axis of movement of guide sleeve is preferably embodied as coaxially in or is parallel to the rotation of power shaft.Absorption via the motion of power shaft opposite house preferably realizes by being connected in lever motion mechanism, and this lever motion mechanism can have one or two lever, or also can have multiple levers.This lever motion mechanism extends between doorframe in other words at door-plate and doorjamb.According to the present invention, housing can be by metal founding materials or also can be made up of plastics in other words.Corresponding material is selected preferably to depend on required power and is carried out, thereby in the situation of interior door with less power demand, correspondingly also can use plastic member for the housing of servicing unit and other elements.
Come as follows further to improve according to servicing unit of the present invention,, be configured to make spring force to decline in the motion process of open position and/or fastening position in guide sleeve and power shaft chute guide portion, decline continuously especially continuously or substantially.Core of the present invention is at least to make open position and fastening position be associated with the corresponding spring force reducing, and in this embodiment, is associated with the decline of spring force in the path in the region of open position and/or fastening position.This particularly forms in a continuous manner, thereby in end position, there will not be the unexpected variation of spring force.This affects the opening characteristic of door as follows, that is, in the time opening or closing, only perceive the slight raising of power or slightly decline.Power is also only carried out lentamente towards the release of desired end position, thereby there will not be unexpected locking.Towards two end positions or leave on the both direction that each end position (namely fastening position and/or open position) moves, can avoid by this way the unnecessarily high load to material at power shaft.Particularly can be reduced in by this way the hardness of two stopper sections in end position, because power is substantially absorbed continuously or discharges.Also construct by this way in theory the non-constant spring characteristic curve of whole servicing unit, this is because guide chute needn't force to follow straight line in the time of translational motion.Bending portion's section of chute guide portion is also admissible, thereby can realize the bending spring characteristic curve of whole servicing unit.
Also advantageously, for servicing unit according to the present invention, chute guide portion has guide surface, is configured to guide rake this guiding face segmentation.At this, guiding rake and axis of movement particularly surround acute angle.These guide surfaces or guiding rake are connected with the effect of chute pin.Chute pin moves along these guiding rakes or guide surface.That is to say, in the time that power shaft rotates, carry out power transmission by chute pin by these guide surfaces.In other words, chute pin is passed guide sleeve along axis of movement against guide surface thereon by corresponding this chute pin in a direction or another direction.By constructing the guide surface of guiding rake form, can realize to spring force especially simply and especially continuous release or absorption.Can provide especially simply thus and structurally cheaply solution construct according to servicing unit of the present invention.
Also advantageously, for servicing unit according to the present invention, spring assembly is by pre-tensioner.At this, spring force remains on power lower limit in the mass motion process of guide sleeve.The for example open position based on door, can arrange with the several years as pre-tensioner angle, for example, be about 4 ° pre-tensioner to the maximum.In other words, door is crossed tensioning, thereby even also has minimum force in the situation that the power of the reduction in open position and/or fastening position loads.This for example realizes with respect to the corresponding layout of spring assembly by inordinate rotation power shaft or by guide sleeve between erecting stage.This keeps door at open position or in fastening position with minimum power, thereby reduces or prevent shake or the shock of door in each end position even completely.
Another advantage is that, for servicing unit according to the present invention, auxiliary body has damping unit.This damping unit at least reduces the speed with spring force bootload sleeve in portion's segmentation ground.The damping unit fluid damping device that especially preferable configuration is hydraulic damper.It can be configured with two fluid passages, and wherein, one in two fluid passages implements flap valve.The difference of these two fluid passages is their flow cross section, can provide different damping characteristics thereby depend on flow cross section by damping unit.Therefore, while only arriving end position in one direction, can be subject to damping, and in the time leaving end position, can not be subject to damping.That is to say, desired, the motion in end position (namely open position and/or fastening position) of acceptor's dynamic auxiliary is carried out in the mode that is subject to damping.In the time leaving each end position (namely leaving open position and/or fastening position), damping unit as little as possible or completely inoperative, thereby in the time leaving each position, needn't overcome additional damping force.The mobile tool that is subject to damping to each end position has the following advantages, and, completes the artistic especially motion of opening that is.In addition, can avoid door excessively to rock or each single mechanical component is produced and damaged by firm stopper section.
Equally also can be advantageously, for servicing unit according to the present invention, damping unit is at least configured in power shaft, chute pin and/or guide sleeve according to the embodiment in the previous paragraph.Such embodiment has been assisted the compact structure form according to servicing unit of the present invention.Servicing unit preferably can have damping unit in power shaft inside, thereby makes it be configured to the form of damping box simultaneously.
In addition can advantageously, for servicing unit according to the present invention, be configured with fluid passage in order to construct damping unit in power shaft, chute pin and guide sleeve, in this fluid passage, be furnished with flap valve.Flap valve is for example arranged in chute pin or power shaft.Therefore, fluid passage is opened in one direction, and is closed in another direction.This has realized the difference of the direction of motion, thereby can realize arriving each end position and leaving between end position in the difference aspect damping characteristic of having described.In the time leaving end position, be subject to very little or be not subject to damping, and for example providing correspondingly large cross section by opening flap valve.If the translational motion of guide sleeve is carried out in the opposite direction, flap valve cut-off so, hydraulic fluid must be found the path of other alternatives thus.This path preferably has than the obvious less cross section providing by the fluid passage being cut off now.Thus can be to be subject to the mode of damping to realize the return movement of the translation of guide sleeve, thereby in the time that open position and/or fastening position arrive each end position, the damping that spring force is reduced.
In addition advantageously,, for servicing unit according to the present invention, chute guide portion has: with opening the portion that the opens section of stopper section, with closing the portion that the closes section of stopper section and opening portion's section and closing the idle running portion section between portion's section.Also can limit substantially closed or completely closed chute guide portion here.Two portion's sections, open portion's section and close portion's section the each end that is configured to chute guide portion.Idle running portion section is the complete portion's section between these two end portion sections.Open portion's section and close portion's section and there is respectively stopper section, to prevent power shaft inordinate rotation.But also needn't in each end position, very be resisted against on corresponding stopper section at this chute pin.Specifically, open stopper section and close in addition stopper section and can use as the protective device of anti-inordinate rotation, they are not encountered under normal circumstances.The remarkable part of idle running portion section is preferably, there is no change in power situation aspect the power loading of spring assembly.Open portion's section and close portion's section and be preferably provided with guide surface, these guide surfaces brought described according to the reduction to loaded spring force of the present invention.
Another advantage is, for according to the servicing unit described in paragraph above, opens portion's section and closes portion's section and be configured to be mutually symmetrical or substantial symmetry.This means, these two portion's sections have following guide surface, and these guide surfaces have substantially the same angle about axis of movement.The power about the spring force loading by spring assembly that can guarantee thus formed objects or same degree on both sides reduces.Thus obtained for the user advantage is, not distinct between the force characteristic in the time opening and the force characteristic while closing.For two directions of motion, maintain the impression of identical power, thus can the expecting and have identical power according to the user of servicing unit of the present invention of door on both direction.
Can be advantageously according to the embodiment in two sections above, for servicing unit according to the present invention, the hunting range from about 20 ° to about 30 ° of opening portion's section and/or closing the Duan Yumen of portion is associated.If door is for example configured with the total opening angle from about 90 ° to about 110 °, 20 ° of starting are so tasked and are closed portion's section to about 30 ° points.Last 20 ° to 30 ° (when namely opening procedure will finish) are associated with the portion section of opening.Correspondingly, the region between these two end regions, namely door from the remainder of opening pivot angle of about 90 ° to about 110 °, be configured to idle running portion section, do not occur therein or the only very little power variation of generation as far as possible.Corresponding portion section preferable configuration is in the chute guide portion of having set forth.
Also advantageously, for servicing unit according to the present invention, power shaft is arranged in guide sleeve inside.At this, the rotation preferred parallel of power shaft in, particularly coaxially extend in the axis of movement of guide sleeve.Can realize thus special compact structure form, it further reduces the overall size of servicing unit.In the time that spring assembly is for example set to the spring element of helical spring form, this spring assembly also can be installed on the bottom of sleeve.That is to say, helical spring is around power shaft, thereby can further improve the compactedness of total form.
The present invention can further improve as follows, that is, housing has at least one fit engagement position, and it is configured to housing to be fastened on door and/or doorjamb.This can be interior fastening and can be also outer fastening.Therefore, for example, fastening can realization by contact pin is installed, this contact pin can be from being externally mounted to door-plate or doorjamb.According to the present invention, corresponding threaded joints also can be considered as fit engagement position, and this threaded joints makes the inside that is placed to doorjamb or door-plate become possibility.
Preferably further improve as follows according to servicing unit of the present invention, that is, in portion's section that chute pin is guided by chute guide portion at it, there is roller, to be reduced in the friction during guiding.This roller substitutes sliding friction mode and carries out corresponding relative motion in rolling friction mode.Not only friction and affiliated frictional force are reduced thus, and especially abrasion are reduced.The wearing and tearing on surface have also reduced, thereby even have also realized power situation identical or that substantially remain unchanged during using for a long time according to servicing unit of the present invention.
