Technical field

According to the application's title, the present invention is a kind of magnetic force lock that is used for door, and this lockset has and remarkable different feature and the technical advantages of habitual similar lock.

This lock belongs to the class lock that locking bolt includes magnet.What match with described magnet is an iron block or another magnet that is embedded in the door frame opening, therefore when device is in locked position of coupler, two magnets in conjunction with action locking bolt is entered in the door frame.When the people exerts oneself mobile locking bolt when being located at resting position, locking bolt shifts out door frame, and at this moment door can be opened.

An object of the present invention is to obtain accurate running and simplify locking device by reducing operation element.

Another object of the present invention is to obtain a kind of new locking system.

Another object of the present invention is to make locking bolt obtain a more level and smooth rectilinear motion and better guidance system when On/Off.

Another object of the present invention is the block sytem of magnetically-actuated, the interaction work of the magnet of this system by different magnetic poles is arranged, and magnet has prevented the whereabouts of locking locking bolt.Because locking bolt is prismatic, so locking bolt itself do not need the inclined plane, and when door was opened, locking bolt can not stretch out outside the doorframe.

Therefore, the purpose of magnetic force lock with magnet of different magnetic poles is to obtain a kind of effective mode of operation, reaches accurately before the position at two magnets, and the locking bolt element can not attracted by the locked end magnet.Two magnets are to timing, and the repulsive force of magnet will be avoided unnecessary element friction, and locking bolt is smoothly moved.

A further object of the invention is by crash panel is assembled, adjust the position of magnet center with respect to crash panel, the assembling defective or the error that produce when reducing to be installed in door on the doorframe that crash panel has been installed, and magnet can be aligned accurately with the magnet of locking bolt.

Background technology

A kind of lock is arranged at present, when locking bolt is in locked position of coupler, and be installed in magnet in the groove when attracting, will enter the groove box by emergency location.Locking bolt and the supporter that can swing are fixed together, and are installed in the housing, and locking bolt also has a magnet and first magnet co-operation.To be opened with square key actuated locking bolt follower locking bolt, key actuated locking bolt follower makes it opposite with a movement of springs, and spring slows down its motion by a series of levers.When door is opened and key when being in resting position, locking bolt with the effect of the magnet of locking bolt one under remain on retracted position.When the door of opening was closed again, locking bolt will be by magnetic attraction.

Also have a kind of locking system, the direction that stops the swinging mounting element to be return towards locking bolt is rotated.

In this known locking device, locking bolt is driven by follower, follower relies on two parts to drive by rotating square key (door handle or door handle): one is mounted in the rocking lever of an end, another part is the lever by the lever actuated of front, and is allowing to move in angular range to drive locking bolt.Second lever can rectilinear motion by the locking key actuated time.At this moment first rocking lever can not interact with second lever, and door just can not be opened, and in other words, at this moment is in the lock position.

Application model n ⁰200601167 require to substitute traditional drop lock with the magnetic force lock, and when door was closed, a common hidden locking bolt stretched out from door, matches with the locking bolt framework by magnetic force, and magnet is installed in locking bolt or the framework, or the both installs.

Application model n ⁰0170039 main and at least one hidden moving magnet co-operation, therefore magnet is attracted by a metal core when door is closed, and stops the motion of lock.

Summary of the invention

For advantage and its shortcoming of improvement that keeps lockset that the front is mentioned, the present invention proposes a kind of magnetic force lock that is used for door, and this lock has the distribution and the fewer purpose parts of optimum moving meter when operating, and this can clearly see in the accompanying drawings.Door handle drives a swing supporter that links to each other with the locking locking bolt of door, thereby drives follower, but this realizes by a rocking lever is changed into an eccentric lever fully.

This lock comprises substantially: a housing comprises and supports rotation shape main body or the follower of unblanking that the follower of unblanking can be swung the constraint that is subjected to spring force simultaneously in the design point of view scope; Swing element or swing arm link to each other with aforesaid rotation shape main body; A main body becomes one with the locking bolt that has comprised a magnet.This main body also can constitute the main body of locking bolt fully.

Therefore, when door is closed, the rotary door handle, at this moment the locking bolt that comprises magnet is arranged in the housing that comprises an irony part or another piece magnet that is installed on the doorframe, the described locking bolt and the follower of unblanking are return by resting position, unlock, so the door of closing can be opened.

Under opposite situation, when door by being opened to when closing, locking bolt and irony partly align and are attracted, locking bolt enters in the framework in the doorframe, the locking locking device.

Locking system (locking follower) also is arranged in housing, and its installation site can lock locking device and prevent that door is opened.

The characteristics of this lock follower that is to unblank has two radially outstanding or extensions: one drives back-moving spring and makes locking bolt can be returned to resting position, and another help by other lever drives unique rocking arm element in the locking device.

Another characteristics of the present invention are that when the follower of unblanking was rotated, rocking lever also can be rotated, and its swinging end will promote the extend radially portion of a swing support system, makes the prismatic locking bolt overcome magneticaction and withdraws from the groove box.

In the present invention, locking system is fully independently, can only be driven by the extend radially portion of corresponding locking follower, and it can have two positions: the one, and the rotation path that inserts locking bolt swing support component stops its motion, perhaps locking system, another location are the lockings of removing locking bolt.Two positions all adopt traditional maintenance method to keep its position as a spring.

In other embodiments, the magnetic force lock that is used for door is characterised in that the locking locking bolt slides in the side of guiding device, and moving forward and backward of it all is rectilinear motion.Forward motion is to take place when the door of opening is closed.Forward motion makes the magnet of the magnet of locking bolt over against crash panel.

Retreat or the action of withdrawing overcomes magnetic force and realizes by rotating the locking follower.

The block that follower has the direct percussion locking bolt of extension radially extending transversely portion to form of unblanking.When the driving gate handle was released, door was opened, and locking bolt remains on lock under the magneticaction of the wall of the housing that surrounds magnet inner.

In first kind of embodiment, because the second extending transversely portion or the front end of unblanking follower causes an end that opens swing element, an other end is a spring, spring makes swing element link to each other with the position that the block of slide latches separates with follower first extension at the follower of unblanking of unblanking, and therefore inner locking and closing organ separate.The free end of swing element that is subjected to spring force is away from the rocking lever that is driven by the locking follower, and the locking follower can be opened door from the outside.

When the locking follower rotates to the locking direction, rocking lever is promoted and remains on very near the free-ended position of swing element by the front end of corresponding follower.At this moment, the follower of unblanking can not rotate, so locking system is had an effect.

Another embodiment, the rectilinear motion of locking bolt is to realize by other method, by the follower of unblanking, rather than the direct extending transversely portion (resembling above-mentioned first kind of embodiment) by locking bolt, act on swing arm, the free end of swing arm is meshed with one of two parallel arms, parallel arms is fixed by the extending transversely portion of the fixed point of housing and locking bolt, and can rotate around locked end, under hinged effect, just formed a parallelogram like this, therefore when swing arm during or other direction rotation, locking bolt is followed it and is done rectilinear motion.

In second kind of embodiment, lockable mechanism acts on the extending transversely portion of hithermost end and the front end of locking follower, prevents its rotation when it is in the lock position.

According to such design, magnetic force recited above lock is without any the restriction of installing, and because it does not have door handle, so it can directly install, need be in order not to be contained in a left side or a door right side is arranged before the installation.

This lock is not in case after installing on door and the doorframe, need to calibrate, because it can carry out self-calibrating.The back lock is installed is sought locked position of coupler automatically, do not need to adjust the spacing of various parts.

Crash panel need very simply be processed, after it is installed on the doorframe, it with doorframe be flush, can not protrude, therefore have more aesthetic feeling than other known lock device.Owing in the action that opens or closes, be friction-free, therefore be level and smooth noiseless in operating process.

In other embodiment, the magnetic force lock that is used for door be characterised in that the part of surrounding main body and locking bolt and magnet (magnetic locking bolt) be do straight-line, no matter be that the irony crash panel that is embedded in the door frames housing moves to the locking direction under magnetic attraction, the rotation of the follower of perhaps when door is opened, unblanking under the effect at door handle.

In the action of opening, the end portion of swing element promotes the part of main body.Above said end portion mainly comprise terminal outward extending one section.

There are three kinds of preferred implementations that main body is moved.

Another one feature of the present invention is to be blocked in the housing by magnetic force at resting position magnetic locking bolt, so it can not stretch out determined plane, an edge.

The locking system that combines with oscillating follower can only be driven by second door handle in door one side, its feature is when it is in the lock position, foregoing block has directly stopped the combination that has main body and magnetic locking bolt at least, has stoped the straight line of main body and magnetic locking bolt combination to move.

In another embodiment, the locking follower of inclination partly is connected with an elongated segment, links to each other with the axle of a centre again, and such connected mode makes the bigger part in front can stop the combination of main body and magnetic locking bolt to directly act on locking bolt.

In first kind of embodiment, the locking follower has two fixing bottom positions, and passes to prolongation: the one, and the lock position, another is off-position (a release main body).

In another embodiment, the locking follower has stopped moving of main body and swing element.

In second embodiment, the locking follower also has two bottom positions: lock position and lock off-position, the both is by stop limits, and has the extension of a spring and a locking follower to advance the rotation of follower.

In another embodiment, the locking follower directly stops main body.

Lock among the present invention has a specific character, it can be installed in a kind of mode of standard any can lay the unified standard locking bolt the plane on.It does not install restriction, and it does not have door handle, so it can be installed on the door of opening or opening from the right from the left side, and does not need to adjust in advance.

In case locking device is installed on door and the doorframe, does not need to carry out more calibration operation because it can carry out oneself adjustment, find its optimal lock position, can be between the parts of door leaving gap.Crash panel or groove box only need very simple processing when installing, and can not stretch after being installed on the doorframe, give high-grade impression.Because interelement friction is less in the mechanism, and is very smooth and easy and quiet during operation.

Another one magnet or iron plate also can be installed in the crash panel on the doorframe, and its effect is the magnet that attracts on the locking bolt.This specific character is good, and this is because the costing an arm and a leg so a magnet only is installed has been reduced cost of production of magnet, and magnet is installed has been increased the processing time, also occurs mistake during installation easily.

Another embodiment has comprised a prismatic locking bolt in housing, is that locking bolt can not stretch out outside the frontal plate when door is shown in an open position.The characteristics of this embodiment are how to pass through to adopt size and the less parts of quality, make operation smooth and easy accurate with the location, and do not go to consider that this cover drive system is to be used to open door; In any case the locking bolt that lever and the swing arm by the follower of unblanking makes magnet carrier carries out straight line or angled motion, when door at the fastening position locking bolt during over against crash panel, locking bolt is hidden under certain conditions, and displays under other situation.

Therefore, locking bolt and crash panel have adopted neodymium matter magnet.Neodymium is a kind of chemical element, and it can obtain more magnetic force than iron, and it often is applied to similar occasion.Because its residual magnetic induction is can force rate iron high 4 times, therefore, only need a less magnetization element just can obtain identical effect with the more weak bigger magnetization element of residual magnetic induction ability.Mention according to top, this makes package unit save the space.

In addition, repelling can appear before they align in two magnets, and this specific character is because crash panel has adopted the alloy of non iron, preferably adopts zamac.

Crash panel is smaller by the same token, so it can be installed in very shallow door frames.

The present invention also provides a kind of method, even crash panel has been installed on the doorframe, also can adjust the position of the magnet of installing in the crash panel.This method of adjustment make two magnets can over against, the erratic behavior that brings when eliminate installing is better finished the invention purpose of design.

For reaching this effect, be sliding-contact between frontal plate and the crash panel, rather than be consolidated resembling usually.For make they in selected position in conjunction with and fastening, adopts two heads from the outstanding screw of frontal plate, resemble and the sort ofly be positioned at the screw that frontal plate two ends, its head are fixed together frontal plate known to common.The inside of the more close device in position of these two screws, their corresponding nut are positioned at the back of crash panel, and magnet is also in this position.These screws pass installing hole, when needs slip frontal plate, only need pine screw once, adjust to suitable position after, screw screw again.

Other purpose of invention will be described further with reference to illustration in the chapters and sections below, but is not limited to the description carried out.

The specific embodiment

With reference to the numbering among Fig. 1-4, the magnetic force lock that is used for door in first kind of embodiment comprises that a main body, main body comprise around fixed axis 3 and is positioned at the magnet 4 of locking bolt 2 to the swing support component 5 that housing 1 rotates, and locking bolt 2 is with to swing support component 5 fixed.The locking bolt 2 that (fastening position of door) stretches out from frontal plate 6 in Fig. 1 enters groove 7 and is attracted by magnet 8.

Open the door of closing and be located at as shown in Figure 2 position, the follower 9 of unblanking overcomes the effect of lever 10, drives swing support component 5, and swing arm 11 rotates around axle 12 on the central point of described lever.

The follower 9 of unblanking has an extend radially portion 13, lever 10 is laid on the extension, in the position shown in the figure 1, lever is exerted pressure to extension, the end of a block 14 at groove 15 promptly arranged, and block 14 has determined to unblank follower 9 by the terminal position of angle during the square key turns shown in the end among the figure.It also has second extend radially portion 16, and its effect is an arm 17 that promotes rocking element 11.

The rotary door handle is located at lockset position of coupler as shown in Figure 2, rotate the follower 9 of unblanking along clockwise direction, cause rocking element 11 to rotate counterclockwise, the extend radially portion 19 that its arm 18 promotes swing support component 5, it is rotated, locking bolt 2 withdrawals in other words towards the direction that door is opened.

At this moment door is opened, discharges door handle, and back-moving spring 10 makes the follower 9 of unblanking return to original inactive state.Fig. 3 has shown that locking bolt 2 remains on the layout of retracted mode, at this moment can not hinder the pass door operation.Around opening 20, be to be attracted to realize by the metal wall of housing by magnet 4.

With reference to n ⁰, the 21st, the spring of driving rocking element 11, it makes rocking element 11 connect the follower 9 of unblanking, and acting in conjunction resets the unlatching handle.

When door was closed, to position shown in Figure 1, when magnetic locking bolt 5 and the 7 pairs of timings of groove that are installed in the doorframe, described locking bolt was gone in the box by magnetic attraction by position shown in Figure 3.

Fig. 4 and Fig. 1 are that door is positioned at the position of closing.Key and the spring 23 common locking followers 22 that drive in Fig. 4, the effect of spring 23 is to have determined two terminal positions that rotate.Its extend radially portion 24 has stoped clockwise rotating of swing support component 5 (main body), so magnetic locking bolt 2 can not withdraw from groove 7.Rotational action allows in Fig. 1, Fig. 2 and Fig. 3, and this is because locking follower 22 is not got involved wherein or 22 is in the off-position.

The effect of one extension 25 of locking follower 22 is when mechanism is in state shown in Figure 3, and the extend radially portion 19 of swing support component 5 is stopped, and stops its lock position towards locking follower 22 to be rotated.

Fig. 4 has shown that extension 25 is in the off-position, at this moment allows locking follower 22 to rotate counterclockwise, arrive the position shown in the figure up to it, and at this moment entire mechanism is all by locking.

The another one effect of the extension 25 of locking follower 22 is the terminal points as the rotation path of swing support component 5.

Fig. 5 has shown second kind of embodiment to Fig. 8, and lock comprises a housing 1, comprises a main body 5a in the housing 1, and it has determined a linear slide with the magnetic locking bolt 2 that has comprised corresponding magnet 4.Locking bolt is prismatic basically, rather than drop latch type, therefore do not need an inclination slide surface.

Mechanism among Fig. 5 is in resting position, and at this moment door is opened, and locking bolt 2 returns in the housing 1.When the door of opening when being closed, locking bolt 2 is over against crash panel or groove 7, and magnet 4 is attracted by the assembly of the one-component iron material that is obtained by electrolysis of crash panel 7.This material uses in a preferred embodiment.

The follower 9a that unblanks has 13a of extend radially portion and 16a, first effect be in the action of opening door directly the effect of 2, the second of mobile agent 5a and locking bolts be that rocking element 11 is rotated around the fixed axis 12 with arm.Rocking element 11 clockwise rotates under the booster action of spring 21, makes the follower 9a that unblanks be returned to initial resting position shown in Figure 5.This position is limited by block 14, and when the block 14 in being installed in groove 15 arrived Far Left, the follower 9a that unblanks had reached extreme position.

The motion guide system of main body 5a and locking bolt 2 is shown in Fig. 5-8.Main body 5a has an extending transversely portion 26, forms two blocks 27 and 28 on it, and motion in the respective grooves 29 and 30 of housing 1 respectively, the effect of block are the ends of determining that main body 5a moves.

In this embodiment, the guiding process is optimized, and is positioned at another extension 31 below the main body 5a of locking bolt 2, forms the block 32 that another one moves in groove 33 on it.

When at closing time, locking bolt moves (position as shown in Figure 6) to the direction of crash panel 7, and locking bolt 2 is entered in the crash panel 7 (position as shown in Figure 6) by magnetic attraction, and motion process is quiet and level and smooth, not with other element friction.

When device was in state shown in Figure 6, for door is opened, locking bolt 2 was return (as Fig. 7) when follower 9a is unblanked in corresponding handle rotation.During the motion beginning, the 13a of extend radially portion of the follower 9a that unblanks drives it and overcomes magnetic force near the block 28 of the extending transversely portion 26 of the main body 5a of locking bolt 2.The effect of spring 21 is to make the follower 9a that unblanks be returned to initial position.

Fig. 5-7 has shown to have only the lock effect, and locking system is in enable state but under the situation of not having an effect, how finish resting position, fastening position and the position that begins to open.The parts of locking system have: locking follower 22a and its 24a of extend radially portion, and the engaging tooth 34 of its settling position and corresponding spring 23 also have the rocking lever 35 that rotates around fixed axis 36.

Fig. 8 has shown the situation of lock position, in case locking follower 22a turns to other position, the 24a of extend radially portion makes rocking lever 35 rising certain angles, the end of the free arm of close swing arm 11, and the follower 9a that unblanks in this position can't rotate.

Fig. 9 to 12 shown another rely on two length identical, in lower fixed point 39 and the 40 hinged arms 37 and the method for 38 guide main body 5b and locking bolt 2 motions.The hinged arm 37 and 38 the other end are connected on a pair of fixed point 41 and 42 with the extending transversely portion 43 of the fixed main body 5b bottom of locking bolt 2.In this case, the follower 22 of unblanking does not directly act in the combination of main body 5b and locking bolt 2, but the rocking element 11 that is meshed by the extending transversely portion 44 with one of them arm 38 that forms parallelogram acts on.Begin (position that door is closed) by as shown in figure 10 position, make door by being closed to (Figure 11) when opening by the rotation follower 22 of unblanking, rocking element 11 rotates, arm 37 and 38 is rotated around fixed point 39 and 40, cause locking bolt 2 and main body 5b along the direction rectilinear motion return, similar with situation in first embodiment.Secondary spring 10 is used to make the follower 22 of unblanking to be returned to initial position.Be similar to the embodiment of front, secondary spring 10 directly acts on extend radially portion 13.

Fig. 9 is positioned at the position that can not stop main body 5b and locking bolt 2 to be return to 11 locking followers 22, but in Figure 12, (shown the lock position), the extend radially portion 24 that belongs to follower 22 stops the parallel arms 38 with its contacted extending transversely portion 44, and the follower 9 of unblanking can not be rotated.

Figure 13-16 has shown other embodiment, and housing 1 comprises a locking follower 9c, 9d, and they can drive by not shown door handle, and they are against on the helical spring 10c; Also have intermediate, inclined arm 45c, 45d, 45e, they link to each other rotary body 9c, 9d with main body 5c, 5d, 5e, and main body and magnetic locking bolt 2 are fixed, during the lock position on the position of locking bolt 2 and the doorframe groove 7 over against; Place another magnet 8 in groove 7 in an identical manner, in door closed closed procedure, magnet 8 attracted locking bolts 2 to do rectilinear motion, in locking bolt 2 attracted to groove 7, guaranteed that door closes.

Yet when rotating rotary body when opening the door to the handle application of force to correct direction, the combination of main body 5c, 5d, 5e and magnetic locking bolt 2 is positioned in the hole 20c of housing 1 up to them with the rectilinear motion rollback and since the effect of magnetic force they will remain on this state.

The motion of the combination of main body 5 and locking bolt 2 is limited by the central axis guide rail 46 in the housing 1, and passes the opening 47 on the frontal plate 6 of housing 1.

In the embodiment shown in Figure 13-16, the follower 9c that unblanks has a 13c of extend radially portion, and it contacts with the alternating share 48 of intermediate arm 45c, and it is crossing with the terminal process 49 of main body 5c that intermediate arm 45c has the projection of an end simultaneously, in the door opening procedure, mobile agent.The follower 9c that unblanks also has another 16c of extend radially portion and spring 10c inconsistent.

In this embodiment, locking system is hinged on the axle 51 by a stretching, extension body 50 and realizes that when being in locked position of coupler, its front up to inconsistent with locking bolt 2, stops its withdrawal than one section long rising, therefore can stop and open door.

Stretching body 50 has a shallow groove 52, and its side contacts with locking follower 22c, and locking follower 22c can be driven by unillustrated second door handle among the figure, makes stretching, extension body 50 be in locking or unlocked position.

Shown another embodiment in Figure 17-20, rotary body 9d has a columniform block 53, with before intermediate arm 45d contacts, contacts with an ancon part 54; Intermediate arm 45d also has one section tortuous profile 55, and is crossing with the terminal part 49d of main body 5d, works in the process of opening door.

In this embodiment, locking follower 22d is arranged on the lock position and directly stops moving of intermediate arm 45d and main body 5d.This realizes by two terminal appendage 24d and 25d.In addition, spring 23 and with the effect of the inconsistent lower protrusion 34 of spring under, reached block 56 and 57 locking or the unlocked positions of determining.

In the another kind of embodiment shown in Figure 21-24, main body 5e and magnetic locking bolt 21 ways of connecting actual with embodiment shown in Figure 13-16 in identical, on the centre pilot device of described main body 5e, trickle change is arranged.

Substantially, locking system comprises a pendulous device 22e, and it has a staggered groove 58; When being positioned at locked position of coupler, groove 58 will contact with the complementary summit of main body 5e.

In another embodiment shown in Figure 25-28, in the process of opening door, when main body 5c withdrawal was moved back, middle swing arm 45e had a lobe part to contact with the terminal expandable part 49 of main body 5c.

In addition, swing arm 45e has a terminal extension 59 to be positioned at the below of main body 5c, and links to each other with swing part 60, and swing part 60 is connected with rotating cam 22e.

In this embodiment, because terminal extension 59 will be inconsistent with rotating cam 22e, stop arm 45e rotates, and therefore, locking system remains on locked position of coupler by locking follower 22e, stops main body 5c to move.In addition, magnetic locking bolt 2 will prop up a section of swing part 60, stop any trial of unblanking, unless the locking system that makes locking follower 22e turn to locked position of coupler is disengaged earlier.Under the effect of locking follower 22e, swing part 60 can keep its locked position of coupler.

Figure 29-the 34th, another embodiment, its default cover magnetic devices comprises a neodymium matter magnet 4 ' that is positioned at locking bolt 2 centers, locking bolt 2 is linear slide in housing 1.Locking bolt is positioned at crash panel or the groove 7 that comprises an other magnet 8 ' in Figure 29.

The frontal plate 6 of lock is the part of lock, must be fastened on the edge of door.

In this embodiment, locking bolt 2 linear slide near or away from block or projection 28, this projection 28 stretches in the groove 29 on housing 1 wall, its afterbody that only drawn among the figure makes the function element in the locking bolt can be in sight like this.Clockwise rotating follower 9f by a position that begins to close the door (Figure 29), when its front or during arm 18 of its 16f of extend radially portion pushing rocking element 11, is this situation.Another arm 17 of rocking element 11 drags the block 61 of the axially-extending portion 62 that is attached at the locking bolt 2 in the main body 5, overcomes the magnetic force of magnet 4 ' and 8 '." opening position " as shown in figure 30.

Opened when door, when door handle discharged, spring 10 made mechanism be returned to its initial position by the follower 9f that unblanks, unless locking bolt 2 remains on the state of returning (seeing Figure 31).

When closing (Figure 32), at this moment the neodymium matter magnet 4 ' of locking bolt 2 can only come mobile locking bolt by magnetic force accurately over against the neodymium matter magnet 8 ' that is installed in the crash panel 7.The length decision of the groove 29 that the length of motion path noted earlier is moved therein by the block 28 of locking bolt 2.

Because the locking bolt of type comprises a traditional locking system shown in the figure, device does not work among Figure 29-31, and locked position of coupler stops the rotation of follower 9f among Figure 32.In fact, locking follower 22f is after by square key actuated, and lifting lever 63 certain angle that moved makes front end 64 stop any contingent motion.Figure 29 and Figure 30 have shown that they are along the motion path of angle direction when unblank follower 9f and rocking element 11 are not stoped by locking follower 22f.

Figure 33-34 has shown a kind of preferred implementation of crash panel 7 ', and the method for the magnet 8 ' of adjustment crash panel 7 ' wherein is provided, and makes it can be easily and arrive suitable position smoothly, so that it aligns mutually with the magnet 4 ' of locking bolt 2.

Therefore, crash panel 7 ' utilizes two screws 66 that pass frontal plate 65 to link to each other in a kind of adjustable mode with frontal plate 65, screw 66 is screwed on the nut 67, and they can move at the enough big hole box 68 that is positioned at crash panel 7 ' end, this in Figure 34 by seeing in the enlarged drawing of the direction shown in the arrow B.

In case being crash panel, benefit is installed on the doorframe, frontal plate 65 is fixed by corresponding hole 69 by screw, the adjustment of lock just can only be passed through the mobile to the left or to the right crash panel 7 ' of level as required, because frontal plate 65 and crash panel both sides have complementary guiding device 70 and hole box 71 to allow described moving horizontally, and so just make the erector can settle magnet 4 ' and 8 ' more accurately when mounted.

By such installation, after in case the crash panel device is mounted, if because coarse installation makes magnet 8 ' not have the correct center that is positioned between door and the doorframe, the required correction work of doing just need be unscrewed two screws 66 just can seeing from the frontal plate, unclamp the end of crash panel 7 ' and move it, arrive correct position up to it, just can screw screw once more then and come fastener.
