As shown in figure 11, first section 32 that body 30 is opened in restriction engages after load bearing arm 12, and stops in second section 14 of load bearing arm 12 and the zone between the end section 15 in the limited open mode of door.In this wide open mode, the sidewall 28 that receives space 8 be pivoted to load bearing arm 12 by in the formed recess of bending.Each

section

13,14 and 15 of load bearing arm 12 is bent to, and when opening, sidewall 28 does not collide load bearing arm 12, although sidewall defines along the circular arc of 135 ° of the maximums of dotted line P.In order to realize especially big open angle, restriction is opened first section 32 of body 30 and also is arranged in the gap 52 of sidewall 28, and it is load bearing arm 12 after even have a big open angle ground joint.

For the fastening position of as shown in figure 12 door, the curved section 14 of load bearing arm 12 extend in the wall 38 of link 7 in formed appearances bags 39.Hold bag and make and especially first section 13 can be set to long especially and make that the bending of second section 14 is sharp-pointed especially that this has realized the king-sized open angle of door.

The elastic movement that body is opened in restriction illustrates in further detail now with reference to Figure 13 and 14.

Figure 13 shows the sectional view of link 7, and wherein, restriction is opened body 30 and sat idly on described link 7.In this case, arm 33 is at area supported 36 upper supports at oblique angle, the oblique angle and first section makes progress at kink 46 places.Second section 34 leaves from arm 33 oblique angles at kink 48 places, and is connected to link 7 and thereby is connected to door by screw 31.

In Figure 14 from sidepiece with the identical parts shown in the mode of height explanatory view, the

section

32,33 and the arm 34 of body 30 opened in restriction only shown in broken lines in the figure.On behalf of the restriction that is in the sitting position, solid line open body 30.Dotted line has been represented at door and has been in the shape that body 30 is opened in restriction in the state in its limited open position.Then, power F1 is applied on first section 32 by load bearing arm 12.Therefore the kinetic energy of being carried is designated as in Figure 13 and 14 in two resilient path of R1 and R2 and is absorbed.

Depend on that power F1 acts on the distance of the kink 46 on first section 32, first section 32 can be along direction R1 deflection, thereby its is crooked in the direction.Because first section is short relatively (roughly 5 to 10 millimeters), thus it will be only crooked one relatively little amount.In addition, bend radius can also flexibly increase at kink 46 places.First section 32 reaches about 0.3 millimeter to 1 millimeter along the maximum deflection of direction R1.In order to produce the enough spaces at this deflection, upper curtate 32 separates a gap with side wall section 51.This gap has about 0.5 to 2 millimeter, 1 ± 0.2 millimeter width e preferably approximately.

On the other hand, arm 33 and if necessary also have second section 34 along being designated as the direction of R2 to up-bow.In this case, arm 33 is being sat idly in the zone of kink 46 on the area supported 36, thereby power acts on area supported 36, sees arrow F2.In addition, tension force is also effect on second section 34 if necessary, and it is transferred to circumocular recess.Because the big relatively length of arm 33 (about 20 to 30 millimeters), so that described arm will bend visibly will be curved, and will be for example along curved about 0.2 millimeter to 2 millimeters of direction R bow.In this case, arm and if necessary also have 34 bendings of second section and absorb elastic energy in doing so.In addition, the bend radius at kink 48 places and thereby the angle of bend at 48 places can flexibly increase, as shown in Figure 14.

Elastic movement R1 and R2 illustrate in Figure 14 large.The power that occurs when door arrives its stop part will be partial to the area supported 36 (power F2) and the circumocular recess at the oblique angle below be positioned at.In this case, power is distributed into well enough and is avoided damaging link 7.

The present invention thereby a kind of flexible door stop part is provided, its power that occurs when arriving its stop part with the flexible way receiving gate also thereby prevents overvoltage.
