At first see figures.1.and.2, the door holder retaining 100 among first embodiment generally includes: body 102 (in Fig. 1 and Fig. 2, can only see the foundry goods of door holder retaining), and described body 102 is fixed on the door 10; Loudspeaker 104; Piston 106, described piston 106 comprise and are positioned at being used for the foot 108 of ground engagement and being positioned at the button 110 of the other end of an end; Keep configuration (not shown in Fig. 1 and Fig. 2), described maintenance configuration is used to keep piston to contact with ground and keeps door to open; Discharge configuration (also not shown), described release configuration is used for release plunger and door; And device (also not shown), described device is used to respond the driving gate release configuration by the sound with predetermined properties of loudspeaker 104 perception.Be also contained in door holder retaining hereinafter and discharge in the required related content of quoting of configuration about the related content of actuating device.

In use make itself and ground fluid-tight engagement keep door to be opened by using button 110 to push piston 106.Described piston remains on the appropriate location automatically by described maintenance configuration.If fire alarm is sent, described sound is by loudspeaker 104 perception and send to described actuating device, and described actuating device drives to discharge and is configured to release plunger.If to off-position, can close automatically by then described door by skew for (in fire-proof door constant situation) door.

3 and 4 introduce the door holder retaining in more detail below with reference to accompanying drawings.Described maintenance configuration comprises snap ring 120 and retainer 122, described snap ring can with respect to retainer 122 to all directions (in Fig. 3 and 4 separately the arrow indication like that) rotation freely.The rotation of described snap ring in surface level and vertical plane all is subjected to the restriction of bearing element 124, and an end of snap ring is fixed on the one-tenth shape surface of described element.Piston 106 can slide in last saddle 126 and following saddle 128, and described piston 106 upwards is offset by disc spring 130, described disc spring 130 its upper end be connected to by bolt 132 be supported on the piston and with its lower end under on the saddle 128.Moving upward of described piston is subjected to the restriction of stopper 134.The xsect of the bar portion of described piston is hexagonal, and cooperates with the big slightly hexagonal hole 136 of the hexagon of xsect of the described bar of ratio portion on the snap ring 120.

Should be appreciated that snap ring 120 can block or release plunger 106 with respect to the angle of piston according to it.Therefore, when piston was pressed, the part of adjacent bores 136 was moved down slightly on the snap ring, and described piston freely continues motion downwards.When the pressure on the piston was released, part relevant on spring 130 mobile pistons and the snap ring moved upward slightly, so that piston is locked in current location afterwards.

The door holder retaining should be appreciated that it is adjustable that above-described maintenance configuration allows the scope of piston, so that can be regulated at an easy rate with respect to the different height on ground.

In described embodiment, the release of piston not only can realize by actuating device, can also be by the override control actuating device by opening or close a realization.This can realize by following steps.Following saddle 128 has almost and piston 106 xsects guide hole of a size, therefore can be used as the fulcrum of piston.On the other hand, last saddle 126 has rectangular slot, and the narrow limit of described slit is parallel with the direction of motion of the retaining of door holder when door opens or closes.Described narrow limit and described piston form and closely cooperate.Therefore described door is when being applied to that acting force is opened and closed in the foot 108, and described piston is easy to take place shaking to a certain degree.Next the swing movement of described piston causes again that snap ring 120 rotates around Z-axis.Profiled surface on bearing element 124 is upwards towards each end bending.Therefore snap ring causes that relative to rotating of eccentric position an end of the snap ring that engages with described bearing element rises to a certain degree, to discharge described piston.Described then piston rises under the effect of spring 130.In this way, the motion of described door has discharged described piston.

In the distortion of first embodiment, bearing element 124 comprises slit.For the sensitivity of the triggering that makes described snap ring can be conditioned, can adjust by screw in the upper surface and the gap between the lower surface of the slit on the described bearing element.

With reference to Fig. 4, discharge configuration (driving) and comprise the motor 150 that produces power by actuating device by actuating device, described motor 150 is by reduction gear 154 drive screws 152.Described screw rod is screwed into or the corresponding swivel nut 156 of back-outing, and described swivel nut 156 is in abutting connection with snap ring 120 and can not rotate, so that described snap ring 120 rotates around transverse axis.Therefore the rotation of motor 150 causes snap ring to keep or release plunger 106 according to its rotation direction.If piston is discharged by snap ring, described spring 130 is used for described piston is retracted to its off-position, discharges described door successively in described off-position.

Actuating device is used for motor 150 electric pulse with enough perdurabilities is provided, can drive swivel nut 156 from an extreme sport to another extreme sport.In excess time, energy does not offer described motor.

In the interchangeable embodiment that discharges configuration, described configuration comprises that the permanent magnet (may be the rare earth element type) that is positioned on the described snap ring is used for substituting motor, and the permanent magnet of described type can be by the electric pulse of suitable energy the conversion magnetic pole.Such magnet is fit to by strontium, barium ferrite, and neodymium iron boron or ferrous acid samarium form.Described permanent magnet is arranged on the described snap ring like this, and it just can move between the magnetic pole of switchable permanent magnetic body with snap ring.The described like this permanent magnet that is positioned on the snap ring just can attracted to a magnetic pole or another magnetic pole of described disposable magnet at any special time according to its polarization down to snap ring.The motion of the described snap ring that is produced by the conversion of permanent magnet is arranged for and suitably keeps or discharge described piston.

In other the interchangeable embodiment that discharges configuration, described configuration comprises the bistable latch that can find on the brake(-holder) block of retractable ball pen or loft door, described latch is used for optionally keeping snap ring in its hold mode or release conditions.Described latch can provide power by solenoid.

In fact, the bistable electromechanical assembly of any suitable type all has advantage obviously, and have realize to keep or during release function not consumed energy and only need be when the state from a functional mapping to another function changes catabiotic advantage.The bistable actuator of other adequate types can be remanent magnetism solenoid actuator, latching solenoid actuator or anti-solenoid actuator.

Introduce described actuating device with reference to Fig. 3 to Fig. 5 below.Described actuating device is represented with 160 in Fig. 4, comprises each parts that are installed on the printed circuit board (PCB).

On a part of actuating device, amplifier 162, amplified, be sent to then from the output of loudspeaker 104 and be used for determining whether described alerting signal (sound) is the device of the signal of predetermined properties.Described device comprises rectification and filtering circuit 164 and comparer 166.Rectification and filtering circuit will be outside the 500-1000Hz scope any target signal filter.Then, described signal by filtering is sent to comparer 166 and compares with the duration threshold value (5s) and the intensity threshold (65 decibels) that are stored in the threshold value memory 168.Any signal that surpasses described threshold value by by or door 170 send in the just driving of monostable device 172, send to motor 150 by bridge driver 174 then.Therefore above-mentioned any sounds trigger actuating device with predetermined properties disposes and discharges described piston 106 and discharge described door with this to drive described release.

The described characteristic that is used for tested sound can change according to the sound of described door holder retaining Expected Response.For example, need produce the sound of particular type by legal provisions in the fire alarm of many countries.The sound needs that are used to test change in view of the above.As standard, between 100 to 3000Hz, the duration is 2s at least usually for the frequency of traditional fire alarm sound, and intensity at least 55 is to 60 decibels, but higher intensity is also the most frequently used.The value of other of these parameters in fact also can.If fire alarm sound has two fundamental frequencies, then by testing two fundamental frequencies respectively, the possibility of inefficacy has just significantly reduced.

As Fig. 5 be clearly shown that, energy only offers the critical piece and the motor 150 of actuating device when main micro switch 176 is closed.As seeing in Fig. 4, described switch is only just opened in 178 off switch of the member on being positioned at piston 106, and this situation only just takes place when described piston is pressed.Therefore the pressing position of described piston is the effective stand-by state of described actuating device, and described off-position is effective closed condition simultaneously.Like this after correct sound has made described actuating device driving motor, even described sound still exists, described actuating device and motor will be closed, and be reduced to zero or some negligible quiescent value (typical 30 μ A) like this after the current drain.

After driving, when described piston 106 was pressed, described motor 150 was reset snap ring 120.Therefore described pushing closed described switch 176, triggers monostable device 180 successively, the driving motor conversely of the negative driving by monostable device 172.Described piston can be remained on pressing position again after the snap ring of resetting.

Therefore actuating device 160 comprises battery carrier 182 by powered battery.Described door holder retaining is designed to can work at least one year with a Battery pack, and cell voltage watch-dog 184 also is provided, if cell voltage drops under the default safe and reliable threshold value, then described watch-dog 184 produces output signal.The output of watch-dog 184 by or the door 170 just driving that flows to monostable device 172.Therefore, if produced the low battery voltages signal, then piston 106 is released, so that described door can freely be closed.Further, the low battery voltages signal is sent to B (oppositely) input port with door 186, and described another input port A with door 186 is connected on the switch 176.When A activates and B when not activating, describedly be activated with door output.Like this, the low battery voltages signal can make the negative driving of monostable device 172 invalid to prevent resetting of snap ring 120.Therefore in a single day detect the low battery voltages state, then actuating device is used to discharge and keep the piston 106 of release.Up to putting into new battery, described door holder retaining is just started working.This is safe and reliable characteristic.

Another security feature is that then snap ring 120 is released if destroyed to the access door 188 of battery chamber.Need unclamp bolt 190 in order to open access door.Yet, unclamp bolt and be arranged to access door micro switch 190 is connected.This can trigger monostable device 194 and be used for release plunger 106.Be replaced (and described battery is in place) up to access door, described door holder retaining just can be reworked.

Connect the door holder retaining of introducing second embodiment with reference to Fig. 6 and Fig. 7 below.Represent with same Reference numeral with parts same among first embodiment.Second embodiment is similar with first embodiment on a lot of basic skills.

Introduce the essential characteristic of second embodiment below.Door holder retaining 200 comprises casing 202, and described casing is fixed on the door 10, removes lid 203 and exposes battery 281, printed circuit board (PCB) 261 and micro switch 276, and when Manual pressure put on cylinder pad (piston button 210), then described micro switch 276 was closed.This allows electric energy flow on the switch 260 (actuating device) and makes it be in stand-by state.When hearing local independently fire alarm, switch 260 cuts out and allows energy Flow and drives solenoid/motor 250, and described solenoid/motor 250 discharges snap ring 220, and allows cylinder (piston 206) to bounce back under the pressure effect of spring 230.Next, make micro switch 276 get back to open mode and stop power supply solenoid/motor 250.Fire alarm can also continue to sound, but described cylinder is released, and power consumption is 0 basically.

Battery 281 can also be had the life-span above 1 year by calculating.When the electromotive force deficiency of battery 281 so that 250 work of solenoid/motor the time, piezoelectric sensor 296 gives a warning.

When switch 260 was triggered so is in stand-by state, LED298 was luminous.

Can realize the manual release of door holder retaining by the bared end of mobile snap ring 220.

The specific feature that should be noted that in a second embodiment is that at first, as shown in Figure 7, suitable comprising disposed in release in this embodiment: solenoid rather than motor.The second, spring 230 is arranged in and different position, the first embodiment position.The 3rd, the xsect of the bar portion of piston 206 leniently is tapered so that pushing of piston can trigger switch 276 to narrow.

In the distortion of second embodiment, the body 202 of door holder retaining is hinged on the described door.If therefore (for example) door holder retaining is connected to the outside of door, even then piston is held pressed state, described door also can be opened (but can not close).

In another distortion, piston 206 is provided with foot, and described foot is hinged on the piston (for example, if described foot is made by rubber by the wing of rubber).Even piston keeps pushing door is opened.

In a word, the door holder of second embodiment retaining has remote-operated delivery system.All ingredients all are positioned at casing, and described casing is fixed on the fire-proof door.The fire alarm sounds trigger switch of regional area, described switch make from the current drives electromechanical assembly of battery to discharge cylinder.

At this 3rd embodiment of door holder retaining is described with reference to Fig. 8 and Fig. 9.Equally, with first embodiment in identical part represent by identical Reference numeral.In this embodiment, the body 302 of door holder retaining 300 is installed on the wall, rather than is installed on the door.Three optional installation sites are shown.Described door holder retaining comprises the fabricated section 301 of multi-functional tilt adjustable.

In the 3rd embodiment, piston 306 separates with body 302 fully, and is installed on the door.Will be appreciated that described piston and body should aim at when mounted.In the same way as of second embodiment, described piston can keep the spring of the part of configuration to remain in the body with body engagement and by snap ring and formation.

Introduce details with reference to Fig. 9.In the 3rd embodiment, described actuating device is described with reference to first and second embodiment of preamble introduction.The solenoid 350 that has the return spring 351 that is in compressive state disposes as discharging with actuating arm 353.Keep configuration to comprise: snap ring 320, described snap ring 320 can engage with the locating slot 307 at piston 306, to keep or release plunger.Actuating arm 353 becomes certain shape so that it can engage with the afterbody of snap ring and promote snap ring so that described snap ring engages with locating slot 307 formation or breaks away from.Therefore, actuating device can make piston keep or discharge.

The effect that piston 306 is arranged in disc spring 330 engages with body 302 down, and described disc spring 330 is installed in the fixing spring case 329 and engages with spring pad 331, and described spring pad can slide in housing.Like this when snap ring 320 release plunger 306, piston even door can be under the effect of spring away from the body of door holder retaining.
