The present invention is specifically related to a kind of handling device that is used for operating lift doors.

Prior art is to realize the operation of vertical axis by motor, wherein rolls up the elevator door of folding and centers on the folded or coiling of described vertical axis volume, and described motor is in the outside of axle itself, thereby a formation and an operating unit of separating.At the U.S.-A-6,082, can see in 499, for example in Fig. 1, operating unit is how to be installed in the top of lift car: it relates to the most tangible solution and is used in practice, its major defect is that it need leave the space in the top of car, and thereby it increased the bottom-to-top-height of lift well.

Solution shown in France-A-2800055 is not predicted the motor that is assembled on the vertical axis, wherein door is folded around described vertical axis volume, because door is not directly operated from vertical axis in this case, but, dragged by the complication system of the thin cord that drags two sects at the place, the upper and lower that flushes with upward guide piece and upward guide piece respectively of door.Except door dragged the complexity of rope, this solution also needed to be used for the space of motor and speed reducer structure, and this causes the waste of building space.

Summary of the invention

The object of the invention is to eliminate and still is present in current shortcoming in the operating system of the folded elevator door of vertical axis volume at present, and the needs to the space that cause of the main existence of eliminating owing to the motor that is used for actuating doors.The present invention plans to utilize the up-to-date knowledge that is obtained in the field of the belt conveyor of operating internally.

Above-mentioned target is realized by the feature of the characteristic of claim 1.

Employing is made with the vertical axis of the motor of external rotor and internal stator, as the door operation axle, makes can to reduce in previous solution in order to place the necessary overall dimension of an operating electrical machines, and wherein door is folded or reel around described axle volume.Also can obtain a series of other advantages in addition due to the fact that: it is inner that motor fully is arranged on axle, therefore is not subjected to the influence of external factor.We utilize " operation and driven voller " and obtain aesthetically and technically have height simplification, high operating reliability and a solution of the handling device of exquisite elevator door highly.

The related specific embodiments more of the present invention of dependent claims will be explained in the following description in more detail.

Another object of the present invention provides elevator door, and described door is recombinated for all requirements of innovation and actv. door:

The transverse integral size of-lift car is little, requires a kind of flexible door that can roll around vertical axis thus,

-be flameproof, so that satisfy the strict clause about flameproof protection prevailing for the time being in force,

-when when the limited horizontal force in its center applies power, sufficient mechanical resistance should be arranged, and be no more than the maximum flexibility distortion (" bending ") of permission,

-outward appearance grace, therefore and satisfy the defined aesthstic needs of trend of current building.

Above-mentioned purpose can be by realizing with the feature elevator door consistent, that center on the vertical axis coiling of dependent claims.They comprise basic measures to realize fire resisting door, and described fire resisting door (country variant is different to the regulation of minimum time section) in the minimum time section of current law or regulations defined is an air tight or flameproof to fire.These measures are rigidity around any imaginary horizontal shaft, and reel around any vertical axis, so that can door be rolled around vertical axis with minimum bending radius (r), wherein said minimum bending radius (r) be less than 1/10th of thickness gate (d).

About the rigidity around the door of any horizontal shaft, the rule in some countries is: if as the power of the above-mentioned 30kg of applying, then the maximum distortion (" bending ") that allows of door is 15mm.As will under the help of various preferred solutions, being illustrated, these rigidity can be affected by different modes, but all be available for a person skilled in the art, wherein said those skilled in the art can select only technical scheme with reference to certain conditions.

Fig. 1 and Fig. 2 have shown that the present invention can be applied to two kinds of forms of lift car wherein suitably.

The specific embodiment

Fig. 1 and Fig. 2 have shown two kinds of forms according to elevator cab door of the present invention, wherein all be the three-dimensional embodiment that simplifies in both cases, in described embodiment, as the law and regulations defined, be contemplated to and have two sects, promptly a sect is directly on car 1, and a sect is used to close the landing entrance of lift well.The door 2 of car 1 is an in-to-in, and the door 3 of landing entrance is in the outside.Preferably, door 2 and door 3 boths have the desired feature of the present invention, even desired in principle feature relates to the structure of elevator door, and elevator door is car door or landing entrance door.Yet in order to obtain the advantage that overall dimension that the present invention plans reduces, door 2 and door 3 be the type as suggested in the present invention as shown in Fig. 1 and Fig. 2 preferably.That is to say that they are around the folded door of vertical axis volume, because only can eliminate the waste that corresponding each elevator suspends the horizontal space of platform (halt station) in the best way by mode like this.At this, we will emphasize the following fact: the present invention solves the structure of the folded door of elevator volume, so we will concentrate the feature of the similar door of explanation, and the ins and outs of the unitary construction of elevator and/or its car are not discussed, wherein said ins and outs cut little ice in the present invention and are well known to those skilled in the art.

Difference between two cars among Fig. 1 and Fig. 2 exists only in the following fact: two sects among Fig. 1, both all can center on door 2 and door 3 two mutual parallel vertical axises and roll (coiling), promptly around corresponding car door 2 the axle 4 and around corresponding stop entrance door 3 the axle 5, and the car door volume is folded (coiling) on axle 6 among Fig. 2, and landing entrance door 3 by the suitable guide part around 90 ° of the axis of rolling 6 deflections of car door, and in case door self is opened, landing entrance door 3 is with a side that self laterally is placed in the car side 1.

The operating mode of door 2 and door 3, and their necessary upward guide piece and upward guide pieces are that obtainable element also is known in practice from the explanation of above-mentioned patent application formerly, thereby do not need they are explained in more detail.

Usually importantly door 2 and door 3 must be " flameproof " herein, that is to say, they must have the essential feature of bubble-tight shut-off, that is to say, in practice, they must be made by the unique continuous surface that does not have hole, passage, crack etc., and make (metal or plastic refractory or the like) by refractory material, so that satisfy the existing relevant criterion of each country.These standards have nothing in common with each other between each country, but they are known to those skilled in the art, thereby the described implication (this notion also is relevant to resisting the time of an opposing pyrotechnics invasion and attack) that those skilled in the art will know that fire protection gate, and he can select only material, be the mixture of each material, so that make the fire protection gate of reeling around vertical axis.

The present invention also concentrates on the engineering properties that the similar door institute as elevator door must have, thereby and realizes similar above-mentioned advantage that is provided in the elevator field.

Therefore, can predict, door 2, door around any horizontal shaft 3 have sufficient rigidity, so that satisfy the regulation (mentioning) that relevant legally time that with the required horizontal force of standard its center applied power under the closed condition of door is allowed the maximum distortion degree of bending in the above.Therefore, allow maximum " bending " in order not exceed, door must have rigidity with respect to its vertical surface.These articles of law by formulation be for fear of, if rest under the situation of interior door heavyly in car overfill or people, the exceedingly outwardly-bent and function that jeopardizes elevator of this meeting.In addition, can predict, folded for door 2, door 3 are rolled up with bending spring r (see figure 2), door 2, door 3 must be reeled fully around each vertical axis, wherein said bending spring r is less than 1/10th of door 2, door 3 thickness, and Fig. 3 a represents the thickness of door 2, door 3 in Fig. 3 f with d.At this, we are appointed as: the whole thickness with d represents door promptly comprises the maximum ga(u)ge that final rib or reinforcing element are measured.Therefore, the landing entrance Men Eryan of corresponding diagram 2, this second clause has provided the accurate indication about the deflection radius of the radius of the axis of rolling 4,5,6 and door.

Therefore, the feature of creative elevator door be around the maximum of each vertical axis reel and competing phase for the maximum drag of each horizontal deflection of shaft, wherein last characteristic depends on articles of law, freely selects and depends on structural environment and first characteristic constitutes the contriver, in order to guarantee described structural environment from the advantage benefit that the present invention predicted.

According to optionally first embodiment shown in Fig. 3 b and Fig. 3 c, can predict, door 2, door 3 continuous surface are made by thin of refractory material, at least one side on door surface (in Fig. 3 b and Fig. 3 c, for example only being reinforced) at the upside of figure by separating each other mutual edge distance mutually and strengthen described door along the vertical bars that its total length firmly is fixed in thin slice 39.Must be in addition clear and definite be, we mention " vertical bars " when herein, we mean when corresponding door 2, when door 3 is arranged in the elevator of control position, in this position with found these rods 310.

Significantly, if refractory material (simple or composite structure, for example be formed into the sandwich structure of a plurality of material layers) thin slice also keep satisfying necessity coiling characteristic of the desired condition of claim, if refractory material (simple or composite structure then, for example be formed into the sandwich structure of a plurality of material layers) the existing sufficient crooked drag of thin slice self, then it needn't be equipped with any strengthening measure (for example shown in Fig. 3 a) by vertical bars or other reinforcing element.Yet, predict to the solution of Fig. 3 f as Fig. 3 b, some strengthening measures are not provided, be difficult to the rigidity of the relevant horizontal shaft of balance and the coiling of relevant vertical axis.

According to a selectivity solution among Fig. 3 b, can predict, rod 310 has the cylindrical cross-section shape.This shape is desirable, because it allows the folded point of Men Zaijuan or inflexion point volume folded, is (firmly being fixed in foil of fire-resistant material if rod 310 has such as the square-section and along their side, then is not this situation) of crossing all surface size in the practice.

In another embodiment of the present invention shown in Fig. 3 f and Fig. 3 e, based on this, continuous surface is respectively by independent thin slice 39 ', 39 " make; and having the vertical ribs 311 that is provided with the phase mutual edge distance of rule, wherein is by pressure-formed thin slice in mould (situation of Fig. 3 f rib 311) or by thin slice 39 " local deformation (situation of the rib 311 of Fig. 3 e) obtain vertical ribs 311.

According to another embodiment of the present invention, can predict, the fire prevention continuous surface, promptly the thin slice of refractory material is made by metal sheet, be preferably thickness at 0.2mm to the corrosion-resistant steel between the 1mm, preferably thickness is 0.3mm.In order to realize the solution shown in Fig. 3 c and Fig. 3 e, this specific embodiment is suitable especially.Use sheet metal, particularly stainless advantage apparent (fire-resistant, high elastic coefficient, or the like).In any case this solution need be used foregoing suitable vertical strengthening measure.

According to another preferred embodiment, in Fig. 3 a, be schematically shown, can predict, flameproof continuous surface is made to the thin slice of the refractory plastic material the 10mm 39 at 2mm by thickness, and preferred thickness is the refractory plastic material thin slice of 3mm.The thin slice of this refractory plastic material, promptly the problem of the thin slice of the refractory plastic material of selling with different titles and brand on market at present is, thinks as the present invention, the described crooked drag around horizontal shaft when door is assembled into elevator must be high.This shortcoming that may have for the thin slice that alleviates refractory plastic material, as shown in Fig. 3 d another be embodiment optionally, can predict, be provided with stirrup high elastic coefficient, that be evenly spaced apart each other, can strengthen described thin slice by in its mass, embedding; And after the door assembly, they will get the upright position in lift car.

According to another form of implementation that can farthest reduce lift car transverse integral size, can predict, bending spring r at 3cm between the 20cm.

The coiling elevator door can advantageously be formed into: around

vertical axis

4,5,6 (Fig. 1 and Fig. 2) roll-up door that is arranged in an open side or the folded door of volume, or door is folded 90 ° from its open side volume, shown in the landing entrance door 3 of Fig. 2, and be directed into upward guide piece 7 and upward guide piece 8, wherein said upward guide piece 7 and upward guide piece 8 are straight after bending like this.Under second kind of situation, the operation of external door preferably green phase is answered dragging of car door and is produced, and under the situation of roll-up door, the operation of door will preferably take place independently, the corresponding axis of rolling 4,5 or 6 of motor-driven.These motor-driven problems are familiar with by those skilled in the art, and nowadays main mode by chain-driving or tooth engaged transmission solves.

Can predict from another preferred embodiment, the fire prevention continuous surface, promptly each foil of fire-resistant material has lines on its outside, thereby strengthens the attractive in appearance of appearance.

Can predict from another preferred embodiment, the fire prevention continuous surface, promptly each foil of fire-resistant material 39 is provided with sound isolating layer.The meaning of this selection scheme is tangible: reduce the noise that the door opening and closing produce, and the caused noise of issuable vibration during the travel of elevator (lift).In the range of choice of having mentioned of the composite wafer of refractory material, this solution must constructively be predicted, and therefore is taken into account in this literary composition.

Except already mentionedly reducing whole dimension, fulfiling the advantage of articles of law of relevant flameproof protection, also relate to the simple relatively advantage of structure of door, this has benefited from and can directly move it and it static property by operation of roller bearing or the folded axle of volume.

At last, we should not forget the artistic advantage of outward appearance, and this type that has benefited from the folded door of volume of elevator is suitable for various traditional and buildings innovation.

Because safety, lift well landing entrance door 3 can not be provided with suitable handling device, and must be opened by the effect of dragging of car door 2.Can prevent effectively in this way that landing entrance door 3 from opening and lift car 1 does not exist, this will determine usually whether car put in place to those and bring titanic peril with regard to the user who hurries into elevator.So for example under the situation of Fig. 5, the axis of rolling 5 of door 3 will never be opened by handling device.Because suitable device, as the door 2 of car 1 and door 3 the elevator door of landing entrance, must remain and close, and only be opened by the precise opening order, wherein door 2 the handling device of car 1 must can overcome the power that is applied in, and the described power that trends towards closing door is applied on

door

2 and 3 by spring or counterweight or other device.

This all will observe the concrete law about safety in the All Countries now, and we do not discuss related law, because it relates to knowledge well-known to those skilled in the art.

The present invention in fact relates to around the operating mode of the folded elevator door of vertical axis volume, promptly as mentioned above, the operating mode of the door 2 of lift car 1 will consider that landing entrance door 3 is only dragged and dragged all the time so that described landing entrance door 3 is opened, and this is mechanically finished by door 2, and all excess time inside door must keep closing the danger of opening to prevent to meet accident.

Door 2, door 3 are directed in upward guide piece and upward guide piece, and described upward guide piece and upward guide piece mark with

Reference numeral

7 and 8 respectively.

Therefore, the present invention relates to the operation of the door 2 of car 1 especially, described door 2 is around the folded door with type that the volume closed assembly puts of

vertical axis

4 or 6 volumes, it can be around the folded special angle of these axle volumes, even according to preferred invention form, around these are rolled-up the solution of the door 2 of car 1 (among the Fig. 1 and the Fig. 2 for), and described method of operation is by the characterization of following three pacing factor institutes:

A) during the opening of door 2,

vertical axis

4,6 also constitutes actuator or each handling device of the door 2 of lift car 1.In other words, axle the 4, the 6th by operation and driven axle suitably, thereby satisfies the requirement of all safety switchs, and the requirement of described safety switch is according to existing safety rate and general effectively (will be stopped in case meet with obstruction, return after the of short duration promotion etc.),

B) door 2 of car 1 is subjected to trending towards closing the tractive force of door constantly, and this is the condition of universal demand now and available as we are following with the different modes solution of explaining,

C)

vertical axis

4,6 is made with the motor of external rotor and internal stator.This is a real innovative characteristics of the present invention.Essence is with

axle

4,6 motorizations, it or not the motor outside in the past known pass through spool, as at (the U.S.-A-6 for example shown in the famous file of mentioning in the background technology, 802,499 and France-A-2800055), but a kind of motor type of inserting in entirely in the

axle

4,6, for example described now motor type is used the live roll that is used to transmit the horizontal conveying belt of goods with motorization.These structures of transfer roller are characterised in that: they have shown the internal stator that the little but length of diameter is long relatively, and circular diameter is relatively little but external rotor that longitudinal extent is big.This can obtain, and fully high moment of torsion is and reduced regardless of the diameter of structure, and shown in practice, thereby described moment of torsion is enough guaranteed the perfect functions of elevator door greatly.Similar roller with the internal stator operation in many embodiment forms is business-like, such as frequency drives (frequency-driven) DC machine that for example is equipped with electronic control system (controlling electronic systems), described motor can rotate in the huge number of revolutions scope of maximum from zero, and keep sufficient moment of torsion, such as commutator machine (brushmotor) or brushless machine (brushless motor), or such as the motor that is equipped with speed reduction gearing, described speed reduction gearing between the encirclement shell (surrounding shell) of rotor and rotor, thereby mechanically the revolution of rotor is reduced to the revolution that is significantly less than rotor case.All these solutions all are in order to realize the present invention, and according to the specified conditions of using, and need to consider the economic condition (price is safeguarded essentiality etc.) that satisfies and engineering factor (speed, moment of torsion, size) and select solution.The selection of motor must be made based on the abundant supply in market in the field of operation live roll by those skilled in the art.For this purpose, you can have a look by be mentioned, be positioned at 6592, the technical literature that comprises all necessary technology information that the Interroll SA company of S.Antonino (Switzerland) is provided is so that realize being used to rolling up

vertical axis

4,6 folded elevator door, that can satisfy the engineering factor that the present invention sets.

In order to realize the present invention, the motor that there is no need to require to have external rotor and internal stator extends on all length of

axle

4,6, and described motor only extends just enough on the part of these length.In fact importantly, sufficient torsional interaction must be arranged on

spindle motor

4,6, overcoming the power that trends towards closing door when not being operated when axle (by the way says, the size of power from 10 to 20kg, thereby utilize small size but motor with abundant length just can overcome easily), thus the door 2 of mobile safely car 1.

According to preferred embodiment, be contemplated to, the outer dia of

vertical axis

4,6 that is placed with motor in it is between 4 to 10cm, and preferably equal 5cm, this size is suitable for

axle

4,6 and self constitutes the situation of motor external rotor, and is suitable for following situation: have the shell that comprises all motors between motor external rotor and axle.Above-mentioned feature can be utilized the space better and be suitable for this situation: as shown in Fig. 1 and Fig. 2, door 2 is rolled on

axle

4,6; And be suitable for following situation: be contemplated to door 2 and only be pushed into (solution does not show, but is similar to the door 3 shown in Fig. 2) in upward guide piece and the upward guide piece then in the figure of door 2 around 90 ° of vertical axis deflections.

In elevator cab door shown in Figure 32, we can see, open door section and therefore partly roll around vertical axis 4.Door at middle section by partly " incisions ", so that can see according to spools 4 of executive component of the present invention, as to form door 2.The external rotor of Reference numeral 4 indication motors and be connected in the shell of motor external rotor by Transmission, described Transmission can be learnt from the above-mentioned practice of operation roller such as for example speed reduction gearing (not shown).We do not need to discuss the constructional details of these motors, because these all can obtain from the market now and can have been bought by everyone.Owing to above reason, it is promptly enough to mention the article that are included in these products catalogues at this, such as for example in the catalogue of INTERROLL company, describes these dissimilar motors and their technical characterictic in detail.Very clear, designer's task is to consider present condition (Men size (largeness) and dispose single or double door for example, consideration power, especially " closing power " that must overcome by motor, have be necessary to drive the price etc. of the motor of complex (aggregate)) and select best solution at this purpose.

According to another embodiment of the present invention, be contemplated to, 2 at door is that continue to bear and tend to close the tractive force of door, is applied in the top and the lower part of door at least.This solution helps to eliminate the danger of the dark embedding of door, if door 2 only bears tractive force at asymmetric point, for example only in the top or the bottom of door, so described danger will be very serious.In similar situation, the vertical edge of door trends towards door self is placed with respect to perpendicular line bevelled position, because door was subjected to from the stopping more than from the stopping of opposite side an of side, this can cause the obstruction that caused by limited exciting force.

Tractive force is put on basically on the whole height of door situation beyond doubt perfectly, though do not show yet and can easily be contemplated according to the situation of another embodiment.

Fig. 4 and Fig. 5 have shown the device that tractive force is applied to the end (having shown last end in detail) of door 2.

In this case, we can see draw gear 9, and for example flexible band in Fig. 4, pulls to the right side with door 2, attempts phase coupled columns 3 (hitting) and closes door 2.The upside that has only shown door 2 in Fig. 4 and Fig. 5 also has but identical draw gear can be expected at the downside of door; Therefore door is spurred with symmetrical manner by the tractive force from two draw geares (draw gear that has only shown upside).

Draw gear 9 is at first belt wheel 11 (only can see S. A. in Fig. 5) upper deflecting and pass second belt wheel 12 then, so that get back to door pillar 10, belt wheel 12 is fixed in described door pillar 3.Tractive force, for example the tractive force that is produced by the drag spring 13 that is fixed on another doorjamb 14 acts on the belt wheel 11.The energy storage of any kind all can be used naturally to substitute spring 13.According to preferred selection, we can select cylindrical snakelike spring (worm spring) or spiral spring (both all do not show), but advantageously select counterweight as energy storage far and away and for some reason.This solution not shown in the diagram is to understand easily for those skilled in the art.But its needed creative effort with respect to making great efforts and Yan Yaoduo in the needed creativeness of the solution of utilizing spring type mechanical accumulator shown in Fig. 4 and Fig. 5, but it can obtain and how many irrelevant tractive forces that are applied on the door 2 of the open position of door own, because it does not rely on the degree of spring elongation or compression.Owing to open to motorization door 2 by the electronically controlled frequency motor (frequency electronically controlled motor) of current technology, therefore this advantage of counterweight system is lost, utilize described electronically controlled frequency motor can adjust by the moment of torsion that motor applied on the vertical axis 4 of door 2, no matter the variation of the spring applied force of draw gear 9, so that it is constant to stay open door 2 necessary power, and regardless of door 2 opening degree.If but our which kind of reason positive opening door 2 manually no matter, that is to say the support of the motor that does not have vertical axis 4, it is obvious fully that following shortcoming will become, if that is: adopt spring as energy storage 9, the power of opening door 2 will increase along with the opening degree of door itself.

For the realization of inventing importantly, door 2 bears the tractive force that trends towards closing it constantly, and irrelevant with the device that is adopted for this purpose.

Have external rotor and internal stator, as the vertical axis 4 of door or vertical axis 6 and use that nowadays the motor of the most modern motor driven systems that is provided by the control system technology of controlling by the electronics mode is provided, can solve all problems relevant best, wherein technology road known to those skilled in the art with the manipulation of elevator door.Imagination door when the Men Zaiqi down periods run into obstacle automatically stops, once or repeatedly returning automatically on obstacle, door locked is medium at off position, just enough.About locking, preferably remember the articles of law regulation about safety: elevator door also utilizes mechanical system to be closed and to lock, wherein said mechanical system schematically indicates with

Reference numeral

15 and 16 in Fig. 4 and Fig. 5, and the former indicates normal pin, and the latter indicates the elastic deformation lock.Therefore such mechanical locking system of many types is unworthy explanation as everyone knows, because they play the part of the role at edge in the present invention.

The invention has the advantages that the following fact: it can save the single-piece size substantially, can fully omit at this because distribute to the space of the drive motor of vertical axis, wherein folds or roll elevator door around described vertical axis volume.Elevator door can be used as compact pre-assembled unit and is provided in addition, wherein be equipped with driver element (motor) and may have and itself the building of crossing the threshold in control system unit (electronics).

Be used to have the invention that has been illustrated of the door of single door-plate, add the door that can be used for having two door-plates after necessary the modification, equally also can be used for three or more multi-door plate wide.Importantly, must constitute the control system of door with motorization door (motorized doors) around the folded type of vertical axis volume.
