The length that is enclosed within the helical spring 60 on operating parts 54 other ends equals the length of this operating parts stroke, and its length value is just in time in the number range of the output torque of motor.This means that when if any part of safety device is blocked, the running of motor will be rotated further, and will overcome spring force between lockup period, do not transmit any motion thus to support part 76 and action bars 40.After motor has rotated first half-turn, just change second half-turn over to, make this device get back to elongate member thus and be positioned at the position of contracting.Can protect motor like this, and described situation about blocking is released, Men Buhui is locked in the make position simultaneously.

Improvement embodiment of the present invention shown in Figure 10-17 is used under certain conditions the hinged door that can open to both direction.This application is particularly useful for the general steady pin compartment door of opening in compartment.If steady pin has stoped door, it can only be to external-open but in the ordinary course of things.Need to improve doorframe and hinge so that door can inwardly or to external-open, the safety device among above-mentioned Fig. 1-9 improves by following describing mode.

A kind of improvement is at the elongate member among Fig. 1 22, at its extended position, it is positioned at external surface one side of door, improve the extended position of back at it, elongate member 22 is in the rectangular channel 110 that extends longitudinally, this groove 110 extends along the edge 16 of an opposite side with hinged edge of door, and limits an abutment surface 18 that is used for lock door.Form a projection 112 at 16 places, door edge, and along extending away from the direction of hinged edge, prevent normally that with the stop device that provides door from outwards opening, it is that one shown in Figure 10-12 rotates counterclockwise.Figure 10 shows the door that is fixed on fastening position by the elongate member 22 of extending.Figure 11 shows the elongate member that is positioned at first retracted position, and this moment, door can inwardly be opened, and promptly was clockwise motion in the drawings.Figure 12 shows elongate member and is in second position of contracting in fully, wherein has been clearly shown projection 112, and it allows to make the inside or outside both direction swing in an edge.

Usually, Men edge 16 is strengthened by shaped steel or plastic reinforcement 114.

Device among the accompanying drawing 1-9 and described method move elongate member 22 between the part retracted position shown in the extended position shown in Figure 10 and Figure 11.

It is desirable for does not have improved motor 50 can make elongate member 22 realize moving to the additional of second retracted position, and also makes elongate member be back to the position of the door locked of extension shown in Figure 10.

Figure 13,14 and 15 show an improved action bars 140 and an elongate member 22 at Figure 10, in 11 and 12 corresponding three positions, promptly are respectively extended position, in be reduced to the position of contracting in first and second.Can it is evident that from Figure 13-15 action bars 140 after the improvement has improved guide groove 142, this improvement comprises a diagonally extending spare 144 that extend in the end on the first 44.

To at Figure 10,13,11, and the operation of the safety device between the position of 14 descriptions is as shown in Fig. 1-9, but in case of emergency, promptly in being required, elongate member is reduced to second position of contracting in fully, under the situation that allows the inside and outside hinge rotation of door, then be positioned at the extension 144 on guide groove 142 tops, when improved action bars 140 from position shown in Figure 14 downwards (below described) when moving to position shown in Figure 15, allow operative pin 34 to move to the upper end of guide groove 142, so just securing rod is moved to the position that second shown in Figure 12-15 contracts in complete.

Be installed in release twisted wire 88 on the support part 76 by operation with improved procedure, and realize that action bars 140 is moved down into its extreme lower position, shown in Figure 16 and 17.In this improved, action bars 140 was different from the single parts shown in Fig. 1-9, and it is that interior company headquarters by plate portion 150 and reduced size divides 152 parts of making, and cuts out guide groove 142 in plate portion 150, and interior company headquarters divides 152 to be fixed together with plate portion 150.

Activating on the basis of twisted wire 88 by remote control release lever or other device, this bellcrank 86 pivoted so that, pin 74 is withdrawal from hole 82, and allows action bars 140 to move to its extreme lower position under the effect of gravity and spring 41, as shown in figure 15.Just can swing to both direction with the back door, and when door rotates back into its normal closed position, then need actuating motor 50 to begin to send elongate member 22 back to its first retracted position, allow door only to open as shown in figure 11, after this arrive its latched position of extending fully as shown in figure 10 to a direction.

Can expect that a circle of motor 50 rotates and can not cause sufficiently making action bars 140 to move to the vertical motion of extreme higher position as shown in figure 13 from its extreme lower position as shown in figure 15.In fact two circles rotate and need.

As shown in figure 16, on action bars, also form a via hole 182.This hole be three limits by going out a rectangle to form tongue piece 184, the lower end of this tongue piece is connected with action bars, and tongue piece is out of shape downwards to form an inclined surface 186 and a surface 190 down, sells 74 and can abut on the soffit 190.

When (Figure 15), stop pin 74 moves in the via hole 182 under the effect of spring 78 when action bars 140 is positioned at its extreme lower position, thereby action bars 140 is connected with support part 76 owing to connector 54 is moved upward then.The crank of rotation half-turn makes action bars 140 move to position shown in Figure 14, and in this stage, the ratchet 120 in the pawl device engages with ratchet 122 on the fixture 124 that is installed in doorframe 10.This joint can prevent when crank 52 further rotates, action bars 140 moves down, this rotation can cause support part 76 on action bars 140 to move relative to downward direction, this moving may be because inclined surface 186 can not stop the relative motion between action bars 140 and the support part 76, and only stop pin 74 to bounce back, align with hole 82 up to it, this moment is at the effect downside pin 74 and hole 82 interlock mutually of spring 78, as shown in figure 16.After this motor 50 and crank 52 further rotate, and cause action bars 140 to be back to extreme higher position shown in Figure 13, and the motion of this second stage extremely is similar to the described situation with reference to Fig. 1-9.In this motion process, the end of twisted wire 88 is free to slide by arm 86.

Can learn that from Figure 17 ratchet 120 is installed in one and is fixed on the auxiliary support 176 of the action bars 140 on the support part 76 slidably.This auxiliary support has a pivoting lever 128, and this ratchet 120 and a hold-down arm 126 are installed on pivoting lever 128, and the interior twisted wire 88 that discharges stranded wire apparatus passes the outer end of hold-down arm, and the exterior part 90 of twisted wire is fixed on the bearing 176.One helical spring 130 that is enclosed within on the interior twisted wire 88 is positioned between the end of support part 176 and hold-down arm 126, the ratchet bias voltage is arrived the position that engages with ratchet.One retainer 132 is installed on interior twisted wire 88, and during beginning to discharge door, twisted wire is moved and makes pin 74 from the hole in 82 during withdrawal, this retainer and hold-down arm 126 are abutted against so that ratchet 120 overcomes the effect of spring 130 from ratchet 122 disengagings, make ratchet remain in bonding station under this spring normal condition.

Do not break away from and also have various other improvement under protection scope of the present invention prerequisite, for example can use hydraulic pressure, pneumatic, clock apparatus, or the manual device that cranked rod is rotated substitutes motor.Substitute cranked rod and connecting rod device with a rack-and-pinion or other suitable mechanical device.Guide groove also can have different shapes.Elongate member can along the top of door or the side of bottom is other be provided with, or also can be used as an optimal way and be attached to side and install.In other improved, elongate member can be installed in the door of a direction switch in the middle part across doorframe, thereby at the extended position of elongate member, it occupies a crack groove that is arranged in the longitudinal extension that an edge forms.Safety device can comprise two elongate member in another improvement project, and each all has the mechanically moving device and the control device of its associated, thus make the door can be locked from two sides or any one side according to operator's selection.
