At first describe by means of Fig. 1 to 3 below and do not have the operating principle of consideration according to the door lock 101 of child safety feature of the present invention.In Fig. 2 and 3, illustrate simultaneously according to child safety feature of the present invention.Door lock that does not have child safety feature according to prior art only is shown in Fig. 1.For at the door lock shown in Fig. 1 be one by the known door lock of DE 198 37 248 C2.
Settle a locking lever 12 in a framework 10, it can be around 14 swings of an axis.Snap 16 is stretched between locking lever 12 and the bearing 18 at the open position of the door lock shown in Fig. 2 101, i.e. roof pressure locking lever 12 widdershins.
A clamping device 20 can be rotatably set on the locking lever 12 around an axis 22.The axis 22 of this clamping device 20 on the locking lever 12 between the axis 14 of the position of snap 16 effect and locking lever 12.Described clamping device 20 has a circumference, and it constitutes a partial circle around axis of oscillation.By snap 16 make clamping device 20 with respect to stop surface 28 roof pressures on a backstop 26 of framework 10.The circumference of described clamping device 20 directs into a slippage seamed edge, and the tangent line that it leaves the circumference of clamping device 20 with one 90 ° angle extends radially inwardly.A backstop seamed edge 32 of described clamping device 20 is perpendicular to slippage seamed edge 30.
Described clamping device 20 is arranged on a groove the inside of locking lever 12.This locking lever 12 is in the embodiment shown by two snaps 16 (only illustrating in Fig. 1 to 3) pretension widdershins.That is, on observer's direction of visual lines, be positioned at the front of clamping device 20 and snap 16 is positioned at the back of clamping device 20 corresponding to snap 16 of the view in Fig. 2 and 3.
A binding clasp 34 is made of the eccentric fracture in the clamping device circumference.It points to an opening 36 of facing in framework 10 sides 40 of a hook 38 by its opening at the open position of door lock 101.If described hook 38 passed opening 36 guiding at 95 o'clock closing the door, then its roof pressure is on a contact surface 42 of binding clasp 34 and make clamping device 20 produce counterclockwise rotation.By rotation slippage seamed edge 30 is arrived on the turning 44 of framework 10.Described snap 16 can relax, and makes locking lever 12 around axis 14 rotations, makes clamping device 20 by surface 46 slippages of slippage seamed edge 30 along framework 10 simultaneously, wherein makes surface 46 roof pressures of slippage seamed edge 30 with respect to framework 10 by torsionspring 24.The fore-end 49 of described hook 38 is with 48 contacts of one second contact surface and 34 tractions of clamped device of binding clasp 34.Said door 95 roof pressure seals.Make one to be closed by the door switch 50 handled on locking lever 12 by these motions simultaneously, torsionspring 24 tensionings and by locking lever 12 is acted on the arm 54 opening lever 52 are moved this and are opened lever 52.Be given in the locked position of the door lock 101 shown in Fig. 3 thus.
When door lock 101 is opened, open lever 52 and move clockwise, and make the arm 54 clockwise roof pressure locking levers 12 of opening lever 52 and snap 16 roof pressures are arrived together.Make clamping device 20 still by surface 46 (Fig. 3 to the right) slippage of slippage seamed edge 30 simultaneously along framework 10, turn back to the position corresponding to the door-lock opening position up to clamping device 20 by torsionspring 24 (may with the door acting in conjunction of home appliances shell the sealing of backing down), wherein said hook 38 is released and opens door.Also handle and open door switch 50 when opening door lock by locking lever 12.
Determine the error of hook 38 by the length of slippage seamed edge 30 at locked position.As long as the fore-end 49 of hook 38 is not hit by a bullet out from binding clasp 34, do not rotate as clamping device 20, that is, as long as 12 on locking lever centers on its axis 14 rotations.
As prior art door lock 101 is shown in Fig. 1, compares with 3 with Fig. 2 and have an additional stop-motion body 60, do not consider according to child safety feature of the present invention, this child safety feature prevents by active force internally or the external opening door of closing.The active force that acts on the door for example can be inner steam impringement or outside drawing back.Described stop-motion body 60 for example can be made of the seamed edge on the framework 30 or be made of optional feature.Clamping device 20 by slippage seamed edge 30 before discharging on the turning 44, this stop-motion body 60 prevents that locking member 12 from rotating opening on the direction.By open at first discharge when lever 52 is opened locking member 12 open then the door 35.At every turn all play the effect that discharges locking member 12 unfriendly when opening lever 52 and open, so children also can cancel stop-motion body 60.Can certainly on a door lock 101, constitute according to child safety feature of the present invention by an additional stop-motion body 60 according to Fig. 1.
For example to open utensil door 95 in order getting rid of by mistake, can to make a pin 70 or slide block (not shown) import to groove 71 the insides in the locking lever 12 according to the present invention by children.This pin 70 also can abut in (not shown) on the wall body of locking lever 12 for locking lever 12 only.This pin 70 makes locking lever 12 only be locked in locked position (Fig. 2) around the form fit that rotatablely moves of axis 14 in groove 71 with connecting.Make not release hook 38 and do not open door of clamping device 20 thus.Be positioned at the outside of locking lever 12 at open position pin 70, for example it abuts on the wall body of locking lever 12.Described framework 10 preferably has a sidewall 72 at groove 71 places of locking lever 12, and it has a groove 73.The groove 73 in locked position framework 10 sidewalls 72 and the groove 71 mutual centerings of locking lever.Be positioned at the front of locking lever 12 in the view of this sidewall 72 in Fig. 2 and 3.
Observe stop head 74 of formation from the drawing of Fig. 2 and 3 on pin 70, it accurately imports to groove 73 the insides with small gap at locked position according to the form cooperation of socket connection.The active force that is applied on the pin 70 by groove 71 on the locking lever 12 is delivered on the groove 73 of framework 10 by stop head 74.
Since fine pitch between the sidewall 72 of locking lever 12 and framework 10 pin 70 and on stop head 74 overwhelming majority only produce lateral force and only with small moment of flexure of scope generation.The live bearing that can also avoid high material stress for big active force on pin 70 in an advantageous manner thus and be used in pin 70 constitutes simply and therefore economically, because only produce very minor effect power on this bearing.One such is used for the groove 73 that form fit connects ground fixed stop 74 and relevant fixator pins 70 and also can constitutes at a wall body, it is not the part of framework 10, for example in orifice casing, wherein this wall body must be with the spacing setting small as far as possible with locking lever 12.
On stop head 74, preferably constitute the step part of step, they according to Fig. 1 and 2 perpendicular to the direction of drawing on and therefore on the direction of pin 70 longitudinal axis, extend (Fig. 7).When only locking, locking lever 12 make stop head 74 by a step part, preferably abut in (not shown) on the groove 73 on the sidewall 72 of last step part at framework 10 at locked position thus.Can make the importing of described pin 70 in the groove 71 of locking lever 12 be limited in locked position thus.
The diameter shaping (Fig. 7) that described pin 70 best taper ground reduce with the end towards pin 70.For example when lock damages, when activating child safety feature, also can also open door thus by the very violent active force that strengthens at locked position because since the case surface that the conical in shape of pin 70 makes pin 70 with a little angle of slope, on the groove that for example 20 ° abut in locking lever 12.Thus one by be applied to the door the orifice plate handle on active force on groove 71 and pin 70, act on pin 70 except a lateral force also makes a normal force, it comes out this pin roof pressure from groove 71.Thus in an advantageous manner for example can the emergency opening door when being used for the device of child safety feature, 69 damages of for example stop device.
For there is diverse ways in the supporting that realizes pin 70 motions:
Be fixed on by stop head 74 on the rocking lever 75 at pin 70 described in first embodiment (Fig. 1,2,3,4,5,6,7), wherein the axis of pin 70 is preferably perpendicular to the axis of rocking lever 75.This rocking lever 75 leads to swinging axle 76 the insides of stop device 69, and this swinging axle preferably is made of plastics.The axis of described rocking lever 75 is here preferably also perpendicular to the axis of swinging axle 76.Described rocking lever 75 is preferably in basic rectangular area formation in the cross section, the wherein long outlying broadside of being longer than, for example four times for the endurance that improves for moment of flexure.The axis that is parallel to pin 70 on this long limit.Make rocking lever 75 can bear big moment of flexure thus.Described swinging axle 76 rotatably supports (Fig. 2,3) by a simple sliding bearing 77 on upper end 78 and lower end 79.79 places, lower end at swinging axle 76 are provided with another restoring lever with a bead 84 80.The steel wire of a torsionspring 81 abuts on the end face of bead, always applies an active force (Fig. 4) thus on restoring lever 80.This point plays the effect of the lasting torque that resets by the restoring lever in swinging axle 76 80, and this torque is for 79 direction of observations that point to upper end 78 point to widdershins from the lower end on the axis direction of swinging axle 76.Make pin 70 roof pressure on the direction of the groove 71 of locking lever 12 enduringly thus.Therefore make pin 70 compress into groove 71 the insides of locking lever 12 at each locked position.Activate child safety feature thus.
Need a mechanism in order to remove child safety feature, it prevents that pin 70 from importing to groove 71 the insides of locking lever 12, another adjustment (adjusting) lever 82 is being set on the swinging axle 76 between rocking lever 75 and restoring lever 80 for this reason.The axis of this adjustment (adjusting) lever 82 and lever 75,80 the same axis perpendicular to swinging axle 76.Described adjustment (adjusting) lever 82 is not to resemble other lever 75,80 to guide like that point-blank, but roughly has a bending 83 (Fig. 4) on 79 directions of swinging axle lower end in the centre.The axis of two halfbodies of this adjustment (adjusting) lever 82 before crooked 83 be parallel afterwards, that is, and perpendicular to the axis of swinging axle 76.On second halfbody of adjustment (adjusting) lever 82, promptly between the free end 85 and crooked 83 of adjustment (adjusting) lever 82, near crooked 83, constitute a rectangular slab 86 (Fig. 4,5,6).The plane of this plate 86 is perpendicular to the axis (Fig. 1,2 and 6) of adjustment (adjusting) lever 82.The long limit of this rectangular slab 86 is approximately perpendicular to the axis of adjustment (adjusting) lever 82, that is, this plate 86 is at Fig. 2, and approximate vertical is pointed to downwards in 3 and 4 the drawing.Extension body as plate 86 on plate 86 constitutes a positioning convex 87 and a boundary protrusions 88.This plate 86 and therefore also comprise hook 87,88 preferably slightly wedge shape ground, promptly be shaped on the direction of pin 70, increasing rugosity ground.The thickness of this plate 86 is thinner relatively, for example between 1 to 2mm, thus owing to use plastics to make the plate 86 can be with respect to the bending of minor effect power.A wedge 89 (Fig. 6) is positioned on second halfbody of adjustment (adjusting) lever 82 in addition, this wedge 89 overstriking on the direction of pin 70.
Described adjustment (adjusting) lever 82 preferably constitutes with the color that can discern easily, and it puts in handle always and is used to handle door on the orifice plate shell be substantially to crooked 83 position from free end 85.In this handle shell 93, have a breach slit-shaped, level at handle, can make thus adjustment (adjusting) lever 82 from the outside handle the motion (not shown).Advantageously, described adjustment (adjusting) lever 82 side direction in handle is removable in the horizontal direction, gets rid of the undesigned motion of adjustment (adjusting) lever 82 thus, because this adjustment (adjusting) lever must lateral movement in handle suitably.Children do not accomplish this point.For different orifice plate design variant schemes adjustment (adjusting) lever is positioned on the different height and positions.For this reason for otherwise 69 of identical stop devices need to select the adjustment (adjusting) lever 82 with another bending 83.Can activate child safety feature thus or it was lost efficacy, because the motion by adjustment (adjusting) lever 82 also makes swinging axle 76 rotations and therefore can make pin 70 move to groove 71 the insides of locking lever 12 or from wherein moving out.This must before opening door, make at every turn spring force that adjustment (adjusting) lever 82 reacts on spring 81 in the horizontal direction side direction towards the side end slippage of handle.This point can not be opened door for for example untrained children, because pin 70 is retained in groove 71 the insides of locking lever 12 and by making stop head 74 be fixed on the only motion of locking lever 12 of groove 73 the insides of framework 10 sidewalls.
Can make adjustment (adjusting) lever 82 be fixed on the state of removing child safety feature in a preferred embodiment, that is, need not to make adjustment (adjusting) lever 82 in handle, to move in order to open door.Additionally make a breach (not shown) little, circle be positioned at the handle the inside at this.In the orifice plate shell, abut on the position, a plane at this plate 86 that is arranged on the adjustment (adjusting) lever 82, wherein between positioning convex 87 and boundary protrusions 88, on the position, plane, have a confinement plate (not shown) at releasing child safety feature state.Stop the motion of adjustment (adjusting) lever 82 thus, especially end lock by the positioning convex on confinement plate 87 and turn back to primary importance in the state of activation of child safety feature.Adjustment (adjusting) lever 82 can not be moved, wherein, can not only lock a door thus because the position of adjustment (adjusting) lever 82 makes pin 70 be positioned at groove 71 outsides of locking lever 12.Because the spring force of spring 81 makes positioning convex 87 abut in (not shown) on the confinement plate at the position, plane.In order to activate child safety feature, that is, make pin 70 can move to groove 71 the insides of locking lever 12, must discharge adjustment (adjusting) lever 82 from this position again.For this reason with the object at a tip, for example ball pen injects little, a circular breach the inside on the handle.Positioning convex 87 is lifted to above the confinement plate, and this point is owing to the bendability characteristics of plate 86 can advantageously realize with minor effect power.Make adjustment (adjusting) lever 82 thus because the reset force of spring 81 turns back to the position of activating child safety feature again.Must make adjustment (adjusting) lever 82 horizontal shifted laterally in handle simultaneously the object at a tip be injected little circumferential notch the inside in order to remove child safety feature, purpose is to make positioning convex 87 can lift to (not shown) above the confinement plate on the position, plane and the reset force that reacts on spring 81 by the positioning convex on the confinement plate 87 is thus realized the lock that ends of desired adjustment (adjusting) lever 82.Particularly advantageously at this be, not only need the motion of adjustment (adjusting) lever 82 simultaneously but also need simultaneously a pointed object is inserted into little breach the inside that in fact child safety feature is removed on debug ground thus.
