Embodiment

In Fig. 1 it can be seen that backstop 20 bottom surface, the backstop by means of drilling cam 23 can backstop in window table (it is not shown herein) on face or on door surface.Quadrangle part 30 is located at center, the quadrangle part can around with (herein It is unshowned) rotation of handle identical axis, the handle is torsionally connected with handle carrying piece 15.Quadrangle carrying piece 35 is anti- Turn round ground to be connected with the quadrangle part 30, the main body of the quadrangle part is concentrically surrounded by the handle carrying piece 15.Institute State handle carrying piece 15 and the quadrangle carrying piece 35 be coupling devices K part, the coupling devices can produce From the handle to the moment of torsion transmission of the polygonal element 30 and can stop from the polygonal element 30 to the handle Moment of torsion transmission.The quadrangle carrying piece 35 reaches the cylindrical dead slot 24 in the bottom of the backstop 20 by projection 33 Inwall 44 on.

The main body of leaf spring 40 is abutted on the inwall 44 while surrounding the handle carrying piece 15.By to end Predetermined small distance, formation takes face 17, and the spring 40 sets angled end 42, the angle end and the quadrangle carrying piece 35 raised 33 shape is adapted and is located in the resting position shown described in the handle carrying piece 15 and takes Dynamic face 17 and the quadrangle carrying piece 35 are taken between face 37.In this case, it is described to take face 17,37 at least partly Ground form from one another adaptation.

If rotating handles is together with handle carrying piece 15, then taking face 17 for one can contact spring end 42.Thus pull Spring end so that spring diameter diminishes.Accurately spring 40 now can be slightly along the inwall 44 for cooperation before described Motion.The spring end 42 being previously mentioned is moved to the quadrangle under the further rotating of the handle carrying piece 15 The described of carrying piece 35 is taken on face 37, and thus rotary motion is passed to four side by described raised 33 and carrying piece 35 On shape part.Optimal power transmission is ensured based on shape adaptation.Therefore the leaf spring 40 is used as coupling, that is to say, that described Leaf spring is coupled the handle carrying piece 15 and the polygonal element carrying piece 35 so that as long as described take involved by the movement of face 17 Spring end 42 and the mobile polygonal element carrying piece 35, the moment of torsion acted on the handle is delivered to described polygon On shape part 30.The handle can be rotated freely.

But when moment of torsion acts on the quadrangle part 30 first, the face 37 of taking of the carrying piece projection 33 abuts The corresponding angle end 42 of the spring 40.Thus the spring expands in diameter, i.e., in the corresponding spring end 42 when minutely being compressed.Therefore the spring 40 is against the inwall 44 and clamping, the result is that rotary motion immediately and Prevented completely.

It is clear that the handle carrying piece 15, the spring 40 and the quadrangle carrying piece 35 are symmetrical with described stop The longitudinal center L structures of block body 20 and setting so that ensure the functional independence relative to direction of rotation.In addition it is important that position Predetermined anglec of rotation gap B between two carrying pieces 15 and 35, by the interval between face of taking 17 and 37 and shape It is adapted to determine the anglec of rotation gap, the interval should be greater than the thickness positioned at the middle spring element 42.By this Size, a carrying piece can be rotated (in the range of the B of anglec of rotation gap), without transmitting rotary movement to another take On part, wherein but can act on the spring 40 as coupling.Spring passes through frictional fit --- from shown Resting position is set out --- and clamp and unclamp in the opposite direction in one direction.

A kind of an alternate embodiment of mechanical diode for rotating handles is understood by accompanying drawing 2.The coupling dress Two carrying pieces 35 and 15 for putting K can rotatably be set also around with 30 concentric axis of quadrangle pin.In ring circumferential direction On be coupling 36 therebetween, such as the coupling of two roller pin forms, the roller pin are pressed off each other by compression spring 38 respectively.Institute The handle carrying piece 15 formed with stating bivalve has middleware 50 on each housing, and the middleware has the wing 52 of arch, The circumferential end of the wing has or formed passage 19.The passage 19 of the handle carrying piece 15 in pairs, phase each other To, with an angle tilt and inwardly the ground of polygonal element 30 orient.

The carrying piece 15,35 also has fastener, and the fastener is configured to switch-in part 51 and corresponding recess 56, And be arranged to each other with anglec of rotation gap B so that under shown inactive state the shape adaptation take face 17 or 37 are spaced at an acute anglely.The spring 38 between the roller pin 36 is directed along connection sheet 46, the connection sheet Inwall 44 along the dead slot 24 extends.It is symmetrical between the end face 19 of the wing 52 of the arch of the handle carrying piece 15 The connection sheet 46 set can prevent the spring 38 during rotary motion in outside, i.e., on the dead slot 24 or in institute State the friction on inwall 44；This contributes to the flexibility of window handle.

As shown in Figure 2, in the case of not having coupling in centre, the shape design permission of the carrying piece 15,35 is double The transmission of square rotary motion.But with the face 17,37 under the collective effect of the lozenges 39 in quadrangle carrying piece 35 it Between anglec of rotation gap B determine function described below.

The coupling 36 is located in the gap 55 of about trapezoidal basic configuration, and the gap is by cylindrical inwall 44, the passage 19 and the lozenges 39 limit, and the gap expands to spring 38.Spring causes described in each pair Each in two roller pins 36 is pressed into the wedge-shaped gap 55 as far as possible all the time.

If the handle and the handle carrying piece 15 are moved now, then first can not pass rotary motion When being delivered in the quadrangle carrying piece 35, interval bridging between face 17,37 is taken described in realization.The wing 52 of the arch The passage 19 overcomes the power of the spring 38 to extrude adjacent roller pin 36 and by the roller pin to be tangential on the anchor ring 44 mode extrudes away from the wedge gap 55.The coupling 36 can move freely in the region 55 of expansion.Tightly Then the described of described two carrying pieces 15 and 35 rotatable relative to each other takes face 17 and 37 and is in contact, thus outside to take The further rotary motion of moving part 15 is fully transmitted in the carrying piece 35 of inside.On the opposed end of the spring 38 The roller pin 36 by rotary motion on the inwall 44 the caused friction wedge gap 55 equally therefrom Middle removal.Thus two coupling 36 move freely.The rotation of the window handle is unhinderedly delivered to the quadrangle pin 30 On.

If moment of torsion only touches the carrying piece 35 of the inside first in contrast, then its lozenges 39 can act on accordingly Roller pin 36 on.Active force in roller pin has very little tangential component and one very based on described geometrical condition Big axial component.Thus the roller pin 36 is extruded by the larger power vertically in the inwall 44, as a result to be caused Powerful friction can hinder rotary motion.It is clear that the direct or indirect of the quadrangle pin 30 is rotated in the rotation Cause the clamping of described or each coupling 36 after angle gap B bridgings and further rotation is stopped immediately.

This is probably favourable, and the dead slot 24/44 at least sets a kind of material in edge side, and the material is compared to described The material of quadrangle carrying piece 35 and the coupling 36 has bigger retractility.Thus the internal carrying piece 35 is being rotated When extrude the powered roller pin 36 into the inwall 44, thus obtain a kind of form fit, the form fit allows Bigger torque loads in quadrangle carrying piece 35.

Fig. 3 shows a kind of another embodiment for being similar to Fig. 2 but structure simplification.There was only one herein to install in sidepiece Roller pin to 36, the roller pin by the compression spring 38 to being loaded and being protected all the time when rotating the handle carrying piece 15 Hold in the larger region of wedge gap 55, the gap is relative the inwall 44 and the polygonal element carrying piece 35 Border between formed by its lozenges 39.Handle motion can be carried out unhinderedly, and when acting on quadrangle part 30 Locking is only realized by the polygonal element carrying piece 35 moved together on the contrary after the anglec of rotation gap B is overcome.Pass through door Or a kind of continuous deformation dependent on material of the inwall 44 is grasped as handle caused by the moment of torsion effect of the active side of window Work energy obstacle can be felt for the user.Simultaneously this be also carry out the handle 10 replacement, at least described The mark of the replacement of " internal structure " and/or other safety measure of hand.

Fig. 4 oblique view shows a kind of handle 10 of part section form, and the handle 10 has the He of handle neck 12 Recess 16, the recess axially extend as screwed hole 14.Backstop 20 has guideway 22 and the cam 23 of drilling, The cam is used to accommodate fixing screws 26 (screw thread that fixing screws for the sake of simplicity, are not shown).The casing member 20 is by covering Plate or covering cap 21 cover, and the cover plate or the covering cap can lift ground via compression spring 13 relative to handle neck bottom side Support.The backstop 20 has a dead slot 84 for being provided with depressed part 86, institute in the ground of guideway 22 with center on bottom side State the insert 88 that dead slot shape-ordinatedly accommodates the form of snap ring 25.Being formed in the snap ring has dead slot 24, for rotatable Ground accommodates the polygonal element carrying piece 35, the polygonal element carrying piece torsionally with polygonal element (being herein quadrangle part) 30 connections.In addition the polygonal element 30 has a cross-drilled hole 32, and the cross-drilled hole accommodates latch 34, and the latch crosses described Polygonal element carrying piece 35.Roller pin or roller 36 are maintained in polygonal element carrying piece 35 with arranging in pairs or polygonal element is taken Surrounding place side on part 35；Preferably 4 pairs, wherein having a compression spring 38 respectively between each two roller pin 36.

The handle carrying piece 15 by means of head portion in a manner of being slidably matched rotatably in guideway 22 It is directed and in side and the form fit of recess 16 in the handle neck 12.Counter-sunk screw 18 is by rabbeting the handle The screwed hole 14 of neck 12 fixes the handle carrying piece 15 in the handle 10, more precisely, described hand-held dynamic The upside of the annular flange 54 formed on part 15 is slidably received against inside the backstop 20.The dorsal part of annular flange 54 With convex shoulder 45, the convex shoulder is concentrically around the polygonal element carrying piece 35.The convex shoulder 45 corresponds to the roller The circumferential end of pin 36 forms the passage 19, and the passage is equally inclined at an angle inwardly polygon herein Shape part 30 orients.

It can be seen that, it is illustrated that quadrangle carrying piece described in example 35 has the arm of four spoke forms, and the arm, which has, to be used for The circumferential radius being slidably fitted in the snap ring 25.Recess 56 is connected by means of the lozenges 39 with these arms, and one Denier eliminates anglec of rotation gap B predetermined between the quadrangle carrying piece 35 and the handle carrying piece 15, and the lozenges is just Same the roller pin 36 of spring can be added to trigger self-locking as described above together in couples.

Fig. 5 a show the building block of such a handle with the exploded perspective view overlooked, while Fig. 5 b illustrate what is looked up Corresponding oblique view.It follows that the backstop 20, the bottom can be pinned by bottom plate 28 after single part is installed The carrying bolt 29 of plate can be locked in the corresponding locking hole 49 of the backstop 20.

The function of device essentially corresponds to Fig. 2 and Fig. 3 device in Fig. 4 or 5a and 5b, can lead in figs. 2 and 3 certainly Any optimum position for crossing frictional fit and handle independently realizes self-locking.

The another embodiment according to the utility model accessory can be learnt by Fig. 6 a to 6c upward view.Cylindrical dead slot Handle carrying piece 15 in 24 concentrically surrounds quadrangle carrying piece 35, but (Fig. 6 a) carrying piece under static state Face 17,37 is taken without contact in 15,35 side.With the handle of the bivalve that unshowned handle rotation is permanently connected herein Hand-held moving part 15 has a mid portion 50, and the mid portion has a switch-in part 51 towards the quadrangle part 30, and described four In the in depth internally positioned carrying piece 35 in side shape part axial direction, the carrying piece is provided with the recess similar to the shape of switch-in part 51 56.The wing 52 of arch is connected on the mid portion 50, and the end of the wing has or formed passage 19, and wherein passage is with one Individual angle tilt inwardly polygonal element 30 orient.Single roller pin or roller are provided between the passage 19 36, the recessed of inside same shape is arranged in radial directions to the roller pin or roller in the quadrangle carrying piece 35 Portion 31.The guide pressure spring 38 of the mid portion 50 and locking ball 47 of the two half-unit of the handle carrying piece 15, institute Stating locking ball 47 has and the identical overall diameter of roller pin 36.Locking ball is loaded in the inwall 44 of dead slot 24 by spring 38 On, with same intervals in the dead slot, dead slot or locking depressed part 27 are preferably respectively introduced with an angle of 90 degrees.

Fig. 6 b show a kind of state, and this device passes through the handle and the fortune of the handle carrying piece 15 in this state It is dynamic relative to position described above to anticlockwise.Now, locking ball 47 is reclined by the acting on for angular zone of dead slot 27 Moved inward in the case of on the inwall 44, and the roller pin or coupling 36 and handle carrying piece 15 it is lean-in tiltedly The passage 19 for pointing to rotation axis D is in contact, and is moved on circuit orbit along the inwall 44.If the coupling 36 it It is preceding to be in dead slot 27, the angle configuration of orientation and the dead slot 27 based on the passage 19, it is ensured that the handle carrying piece 15 make the roller pin 36 leave the locking depressed part 27.

The roller pin 36 is entered in the recess 31 of the quadrangle carrying piece 35 simultaneously so that the quadrangle is taken Part is forced to be coupled and be moved with the handle carrying piece 15.The ball 47 being extruded inward rolls along the inwall 44.

If trial makes quadrangle part 30 rotate (Fig. 6 c) from according to the resting position shown in Fig. 6 a, then the quadrangle The angular zone in the female portion 31 of carrying piece 35 can be moved radially outward the roller pin 36.The roller pin 36 reaches the backstop Obstruct in the dead slot 27 of body 20 and directly any further motion of the quadrangle carrying piece 35.It is clear that institute Small angular range can only be turned over by stating quadrangle part 30, and the angular range is limited by anglec of rotation gap B, until the self-locking Suppress every time further rotation.One key character of this structure type is, herein in lock position is illustrated or by Illustrate lock position and realize the protection for being directed to peripheral operation.

Can also to be prevented from the polygonal element 30 to the handle outside the diagram lock position of the handle 10 10 moment of torsion transmission, Fig. 7 a to 7b structure type are provided with a kind of dead slot 24, and the dead slot has four Hes of lock recess portion 66 Four locking depressed parts 67, it is specific as shown in figure 8, the lock recess portion and locking depressed part are relative to the handle 10 and institute The rotation axis D of carrying piece 15,35 is stated into point symmetry and preferably relative to the longitudinal axis and lateral shaft of the backstop 20 Line L, Q are set with 30 degree of angles and 60 degree of angles respectively.Set between the handle carrying piece 15 and the polygonal element carrying piece 35 The coupling 36 put is configured to lock pin.Locking is realized by compression spring 68 and lock pin 47 for finding out the window fittings Significant position, lock pin are crushed on the medial surface 44 of the dead slot 24 or are pressed into the lock of same shape by spring force Only depressed part 67.The rotation of the handle from the significant position cause the lock pin 47 overcome the power of spring 68 from Removed in the locking depressed part 67 and moment of torsion increases for the user.The length selection of the lock pin 47 is to make The lock pin can only be extruded into locking depressed part 67 and be unable to squeeze into lock recess portion 66.To this such as Fig. 8 The lock recess portion is compared both with bigger diameter or with bigger length ruler with the locking depressed part 67 shown in Fig. 9 It is very little.This is same to be also applied for lock pin 36 and lock pin 47.Therefore ensure that, only in the significant position of the handle/accessory The moment of torsion of increase can be felt for the user.And the lock pin 36 can either move into lock recess based on its size The and can of portion 66 enough moves into locking depressed part 67.

Fig. 7 a show the device in the significant position of the handle.The lock pin 47 squeezes into institute by spring force State in locking depressed part 67.The polygonal element carrying piece 35 itself has two recess 31, and the female portion accommodates respectively Coupling 36.Coupling is located at two passages 19 of the handle carrying piece 15 for being formed bivalve with movement clearance as small as possible Between, the handle carrying piece 15 is located at the starting point S shown in Fig. 8 so that described in when rotating the handle carrying piece 15 Shape is produced between the passage 19 of the female portion 31 of polygonal element carrying piece 35 and the handle carrying piece 15 to match somebody with somebody Close.The passage 19 of same handle carrying piece 15 described herein be inclined at an angle inwardly polygonal element 30 it is fixed To.Thus, except as the anglec of rotation gap caused by part manufacturing tolerance, rotation is not present between two carrying pieces 15,35 Angle gap.

A compression spring 70 is fixed in blind hole 71 for each coupling 36 in polygonal element carrying piece 35, is compared Spring force for compression spring 70 described in the spring 68 of lock pin 47 is smaller.The coupling 36 is compressed in by spring force On the inwall 44 of the dead slot 24 or it is extruded into depressed part 66,67.Therefore ensure that, the coupling 36 it is in office when Time can be automatically moved into the depressed part 66,67.

In another (unshowned) optional embodiment, each coupling 36 is added with being radially outward directed by spring force Carry, wherein the spring force is produced by a common spring 70, the spring radially across the handle carrying piece 15 and/or The polygonal element carrying piece 35.Due to being used as locking element, therefore energy simultaneously for coupling described in this structure type Enough abandon using extra lock pin 47 and spring 68.Thus the structure of the accessory is simplified and reduces manufacturing cost.

If carry out operating handle in a manner of meeting function, then the inward slant of the handle carrying piece 15 orients described Passage 19 drives the coupling 36 on a circuit orbit.Outside depressed part 66,67, especially in the aobvious of the handle In the position of work, the coupling 36 causes the form fit between described two carrying pieces 15,35, thus rotary motion all the time Seamlessly it is delivered to by the polygonal element carrying piece 35 on the polygon pin 30.The significant position pair of the handle The significant position of the window fittings of Ying Yuyi connections；Therefore flawless positioning and the window of push rod are ensured by gapless Trouble-free function.

If coupling 36 is squeezed into the lock recess portion 66 or locking depressed part 67 during rotary motion, then The form fit is cancelled and between two carrying piece 15,35 and accordingly will between handle and polygon pin Produce anglec of rotation gap.But further rotating by the handle, coupling 36 are used as via the depressed part 66,67 The end edge of functional surfaces 69 or face are extruded again from the depressed part so that and then establish form fit again.Institute State the anglec of rotation gap that the short time occurs between the significant position of handle be not to the function of window it is unfavorable because it is described significantly Position be seamlessly delivered on the window fittings.

In the case of invasion, the coupling devices K of the handle is loaded with moment of torsion from polygon pin 30.If window handle Hand is in significant position, as shown in Figure 7a, then polygonal element carrying piece 35 can rotate after locking moment of torsion is overcome.If reach Such as the position in Fig. 7 b, coupling 36 can be squeezed into locking depressed part 67 or as schemed by the spring force of compression spring 70 In lock recess portion 66 shown in 7c, that is to say, that the locking depressed part 67 meets to be used as locking depressed part and lock recess The dual-use function in portion.The form fit of the coupling 36 between two carrying pieces 15,35 cancels and the polygonal element Carrying piece 30 continues to rotate relative to the handle carrying piece.By the female portion 3 and its it is used as the angle that functional surfaces work The passage in region 39, each coupling 36 is regularly squeezed into lock recess portion 66 or locking depressed part 67 and It is no longer able to be returning inwardly in recess 31 in further rotary motion.Now in the handle carrying piece 15 and described Form fit is formed between depressed part 66 or 67 in the dead slot 24 of backstop 20.If in the handle carrying piece 15 and described more The shape adaptation of side shape part carrying piece 35 take face 17,37 between existing anglec of rotation gap it is so big so that two Face 17,37 is taken described in carrying piece 15,35 to be in contact with each other, then handle carrying piece 15 equally together rotates to a certain degree.So And the form fit between the handle carrying piece 15 and backstop 20 realized by the coupling 36, prevent described two take Part 15,35 and then polygon pin 30 further rotate.The opening without authorization of the window is impossible.

The scheme of the described form fit of the self-locking need not be very high part dimension accuracy, but described All the time having when the moment of torsion from the polygon pin to the handle transmits is ensured outside the function of handle and lock position The lock function of effect.The rotation between handle and polygon pin is not present in the lock position of the handle or near lock position Corner gap, enabling effectively avoid the failure of accessory.High cost when effectively preventing from manufacturing part.Figure 10 a are to overlook Exploded perspective view the building block of such accessory is shown, and Figure 10 b show the corresponding oblique view looked up.It follows that institute Stating coupling devices K can be formed in a single insert 88.Thus the insert has a cylindrical dead slot 24, Required lock recess portion and locking depressed part 27,66,67 is arranged in the inner circumference 44 of dead slot.The insert is embedded into Close in a shape identical receiving portion 89 in the backstop 20 and downwards block piece body.Therefore bottom plate is no longer needed 28.The coupling devices can by it is simple and easily in a manner of pre-install and be then embedded into the backstop 20, this is right Manufacturing cost produces Beneficial Effect.

Provided in another very favorable accessory according to part of the present utility model, polygonal element 8 is along institute Ground can be vertically moved but be directed to without relative rotation in coupling devices 10 by stating the rotation axis D of handle 6.

Ground can be vertically moved in coupling devices but the polygonal element that is directed without relative rotation in installation fitting from The frame thickness or section bar thickness of the dynamic matching window OR gate provided respectively, without exist it is with different length, The polygon pin that must be suitably selected and be accordingly embedded in.Therefore the operation of the accessory becomes clear simplifying.No longer need Preserve the quadrangle part of a variety of different lengths.In addition ensure, the polygonal element accurately imbeds the machinery of window OR gate all the time In device so that the window or the door can be operated reliably.Safety in operation significantly improves.Especially existing during installation Field can be effectively prevented from by being slipped up caused by assembler.Simultaneously because the function of coupling devices is fully retained, therefore The coupling devices formed between the handle and the polygonal element provide protection against the unauthorized invasion of outside.

In order to Auto-matching length, the polygonal element 8 can preferably overcome spring force longitudinally movablely in institute State and moved in coupling devices 10.The spring is persistently extruding the polygonal element towards window OR gate so that polygonal element can Safely and reliably rabbet into the mechanical device of window OR gate.When pin the is oversize and when mounted pin --- preferably across institute State coupling devices --- when moving back in the handle, while the spring bending.The polygonal element passes through pressure bullet It is favourable that spring, which is supported in the handle,.

The coupling 36 of the coupling devices K can be configured to roller pin, round pin, ball or other forms.It is just described to stop The inwall 44 of block body 20 is provided with for dead slot 27, and the dead slot has the suitable shape matched with the coupling 36；Example As also sliding block or handle carrying piece 15 (Figure 11 b) can be moved by the exchange of the snap ring 25 in Fig. 5 a, Fig. 5 b, then ball 47 Locking can be released, wherein the compression spring 38 is compressed, and interior survey of the lock pin 36 along housing is slided or rolled.Can See, the sliding block in the housing or backstop 20 can move freely.

But if power acts through the quadrangle part 30 and acted in the quadrangle carrying piece 35, then four side The angular zone that shape carrying piece works using it as lozenges brings up to the lock pin 36 in lock slots 27 upwards.Therefore sliding block Carrying piece 15 is locked in the position that it starts to provide already by locking ball 47 and the handle can not move (figure 11c)。
