Fig. 9 is the circuit diagram of arrangements for speed regulation 30.
Arrangements for speed regulation 30 are performed such speed governing.Head in front of the door from open position up to arrive than fastening position slightly before in the process of assigned position P of (shown in d1 Fig. 1), the closing velocity of labeled door 16 is reduced to the 1st slow speed of closing velocity that produces than from locking mechanism, and the process from assigned position P to fastening position, then speedup arrives than the 1st fireballing the 2nd speed.With reference to Fig. 9, the circuit of the arrangements for speed regulation 30 of present embodiment is described, arrangements for speed regulation 30 have: generator 56; The 1st variable resistor 64, it is arranged on the output of generator 56; The 2nd variable resistor 66, itself and the 1st variable resistor 64 also connect; Change-over switch 68 and 70, it is used for switching between the 1st variable resistor 64 and the 2nd variable resistor 66; Switch switching part 72, it is arranged on (as shown in Figure 1) on the building side.This switch switching part 72 is arranged on position (opening direction) before the fastening position with labeled door 16 at a distance of the place of predetermined distance d2.To make head in front of the door when labeled door 16 when being in assigned position P when determining this predetermined distance d2, can make change-over switch 68 and 70 actions by switch switching part 72.When labeled door 16 opening and closing on the direction with respect to the switch switching part be positioned at evolution to the time, make electric current flow through the 1st variable resistor 64 by change-over switch 68 and 70, change-over switch 68 and 70 just is switched by switch switching part 72 along with labeled door 16 is each when opening and closing, and resistance value also is switched.
With reference to Fig. 5 and Fig. 7, the pressing device 18 of the blocking device 1 of present embodiment is described.
The action of explanation pressing device earlier, when labeled door 16 began to close originally, promptly, at Fig. 2, among Fig. 5, when labeled door 16 is mobile from left to right, until the position that arrives labeled door 16 shown in Figure 5, cranked rod 32 above the labeled door spring 42 that all is stretched is limited in primary position, while keeping assigned position (position of representing with solid line among Fig. 5) to close, during position before arriving full cut-off shown in Figure 5, the revolving body 38 of the long handle side of cranked rod 32 connects with turning to support 44, cranked rod 32 rotates then, accompany with it, the revolving body 40 of the short handle side of cranked rod 32 connects with support 46 with pushing, pushes labeled door 16 later on gradually.When full cut-off, labeled door 16 is urged predetermined distance, thus the pushing be arranged on peristome 3 sides every the cigarette member, make peristome fully every cigarette.
Illustrate in greater detail the action of pressing device 18, labeled door 16 is moved to closing direction (in Fig. 5 and Fig. 7 from left to right).Before labeled door 16 arrived fastening positions, be stretched spring 42 of cranked rod 32 applied power towards closing direction, is positioned on the primary position shown in Figure 5.Before head arrives fastening position in front of the door (position shown in Figure 5) of labeled door 16, be arranged on revolving body 38 on the front end of long handle 37 and be fastened on and turn to on the face of support 44.When labeled door 16 again when closing direction moves, rotating crank bar main body 31 is because of turning to the pushing force that produces with support 44 resistance springs 42 and opening for middle mind-set labeled door 16 that direction is counter to be pushed away with axis of rotation O '.That is to say that in present embodiment shown in Figure 7, cranked rod main body 31 is to revolution counterclockwise.In this process, the revolving body 40 that is arranged on short handle 39 tops connects with support 46 with pushing.
Pushing is born the power that is given by short handle 39 with support 46, but because pushing is fixed on the 2nd upper ledge 14 with support 46, so in the revolution of cranked rod 32, along with the revolving body 40 on the top of short handle 39 is urged, labeled door 16 to the opposition side of pushing with support 46, promptly, the 1st upper ledge 12 side shiftings, as shown in Figure 7, on the fastening position that labeled door 16 has been closed fully, labeled door 16 is urged on doorframe 4.In the present embodiment, labeled door 16 is pressed and is attached in front of the door on the vertical frame 8 of a side, the vertical frame 10 of door afterbody and the 1st upper ledge 12.Owing between labeled door 16 and doorframe 4, be provided with encapsulant 20, so can further guarantee the air-tight state between them.
According to shown in Figure 5, moving to position shown in Figure 7 during this, revolving body 38,40 turns round the limit with support 44 and pushing with the face top of support 46 and moves turning to.That is to say, being accompanied by labeled door 16 moves to doorframe 4, the revolving body 38 of rotating crank bar main body 31 moves along the face with support 44 that turns to that extends as the crow flies on horizontal direction with respect to labeled door 16, in addition, the revolving body 40 of rotating crank bar main body 31, be accompanied by the revolution of rotating crank bar main body 31, move along the face of the pushing of extending with support 46 to the switching direction of labeled door 16.When arriving the fastening position (position shown in Figure 7) of labeled door 16, labeled door 16 is attached on the doorframe 4 by pressing device 18 powerful pressures, because of the frictional force between labeled door 16 and the doorframe 4, labeled door 16 can not be moved to opening direction, rotating crank bar main body 31 stops on the position shown in Figure 7.
Here, with reference to Fig. 3 and Fig. 4, the action when labeled door 16 is pressed to doorframe 4 by pressing device 18 describes.When by pressing device 18 labeled door 16 being pressed to doorframe 4, the installation bracket 26 of door guide roller 24 usefulness is that (clockwise direction in Fig. 3 and Fig. 4) turned round at the center with the joint portion with guide rail 6.But the installation bracket 26 of door guide roller 24 usefulness is connected with the installation bracket 28 of labeled door 16 usefulness in the mode of freely rotating at wraparound shaft axis O, so labeled door 16 moves to doorframe 4 under vertical sagging state.
Below, the occasion of opening labeled door 16 is described, be accompanied by moving of labeled door 16, cranked rod 32 is because the effect of extension spring 42 turns back to primary position along closing direction, therebetween, the revolving body 40 on the top of short handle 39 also leaves pushing support 46, and labeled door 16 leaves doorframe 4.
Below, with reference to Fig. 8 and Fig. 9 the action of arrangements for speed regulation 30 is described.
During beginning,, the 1st speed and the 2nd speed are set for desirable speed by the resistance value separately that the adjusting dial 69 and 71 of variable resistance 62 is regulated the 1st variable resistor 64 and the 2nd variable resistor 66 respectively.The 2nd resistance value of the 2nd variable resistor 66 will be set for bigger than the 1st resistance value of the 1st variable resistor 64, thereby makes the 2nd velocity ratio the 1st speed fast.
Be opened to open position shown in Figure 1 with handgrip labeled door 16, at this moment door guide roller 24 turns round, but by the effect of unilateral bearing 52, the revolution of door guide roller axle 48 is not passed on the gyroaxis 58 of generator 56 via major diameter belt pulley 54, endless-belt 55 and small diameter pulleys 60.Therefore generator 56 does not move.Then, when hand when labeled door 16 is decontroled, labeled door 16 moves to fastening position along guide rail 6 because of the deadweight beginning.Therefore, door guide roller 24 turns round, and via unilateral bearing 52, the revolution of door guide roller axle 48 is passed on the gyroaxis 58 of generator 56 after major diameter belt pulley 54, endless-belt 55 and small diameter pulleys 60 speedups, and generator 56 moves.When the gyroaxis 58 of generator 56 turned round in magnetic field, electrode upper reaches overcurrent uprised voltage by variable resistor, loaded load on generator 56, and gyroaxis 58 is produced brake force.This brake force is passed to major diameter belt pulley 54 from small diameter pulleys 60 through endless-belt 55, passes to door guide roller axle 48 more successively, is loading brake force in the revolution of door guide roller 24.Labeled door 16 has the trend of the walking quickened along the guide rail 6 that tilts, but the revolution of door guide roller 24 braked by this brake force, and the closing velocity of labeled door 16 is decelerated.
Below, circuit is described, on the position, the 1st variable resistor 64 makes its conducting by change-over switch 68 in the early stage.Door guide roller 24 beginning rotates also along the guide rail 6 that tilts and closes, the 1st closing velocity walking of labeled door 16 to have been slowed down by the 1st variable resistor 64.Labeled door 16 is walked to fastening position from open position, arrive in the afore mentioned rules position P at head in front of the door, the change-over switch 68 of the 1st variable resistor 64 sides becomes OFF by switch switching part 72, the change-over switch 70 of the 2nd variable resistor 66 sides becomes ON, and that the 1st variable resistor 64 becomes is invalid, the 2nd variable resistor 66 becomes effectively.Thus, generator 56 is required that bigger electric current is arranged, so the rotating braking of gyroaxis 58 is alleviated, labeled door 16 speedups are to 2nd closing velocity faster than the 1st closing velocity, the fastening position of walking always.
Next, when opening labeled door 16, in the arrival of the head in front of the door afore mentioned rules position P of labeled door 16, the change-over switch 70 of the 2nd variable resistor 66 becomes OFF by switch switching part 72, the change-over switch 68 of the 1st variable resistor 64 sides becomes ON, it is invalid that the 2nd variable resistor 66 becomes, and the 1st variable resistor 64 becomes effectively, and arrangements for speed regulation 30 are reset.As illustrating, door guide roller 24 turns round during labeled door 16 is opened, but because the effect of unilateral bearing 52, the revolution of door guide roller axle 48 is not passed on the gyroaxis 58 of generator 56 via major diameter belt pulley 54, small diameter pulleys 60.Therefore generator 56 does not move.
Figure 10 represents the 1st remodeling example of the pressing device of present embodiment, and Figure 11 represents the 2nd remodeling example, and Figure 12 represents the 3rd remodeling example, and Figure 13 represents the 4th remodeling example.
With reference to Figure 10～Figure 13 the 1st remodeling example～the 4th remodeling example of the pressing device of the blocking device of present embodiment is described.In the 1st remodeling example shown in Figure 10, the pressing device 18 of a pair of and present embodiment is arranged on a side in front of the door and a rear side with respect to labeled door 16 closing directions with the cranked rod of spline structure etc.Specifically, cranked rod 80 is respectively installed 1 in a side in front of the door and the door rear side of the upper surface of labeled door 16 respectively.With them, turn to support 82 and pushing with support 84 also with these cranked rod 80 corresponding positions on, similarly be installed on the upper surface of the 1st upper ledge 12 and the 2nd upper ledge 14 with present embodiment.This occasion is because door afterbody and pressing device in front of the door repeat fully, so longitudinal sectional drawing is the same with Fig. 6.
More than the occasion that a pair of identical pressing device is set is illustrated but also with good grounds installation site and the occasion of a pair of same pressing device is not set.That is to say, when labeled door 16 is opened fully, being installed in front of the door, the cranked rod 80 of a side has under the situation about taking place of conflicting with turning to support 82 of door rear side, can being installed in front of the door by raising, the height of the pillar of the cranked rod 80 of a side avoids conflict, this is that turning to the installation site and the pushing of support 82 of a side uses the corresponding change of height of support 84 to get final product in front of the door.At this moment longitudinal sectional drawing will become as shown in Figure 11.The action of each cranked rod 80 grade is identical with the pressing device 18 of present embodiment.If in the time of being used for improving in advance the height that the rotating crank bar of pillar height uses to pushing with the height setting of support 84 one-tenth, then can use identical parts as universal standard part.
In the pressing device of the 3rd remodeling example shown in Figure 12, used the mechanism of the 1st remodeling example, on the side in front of the door of the upper surface of labeled door 16 and door rear side, cranked rod 86 is installed respectively, is interconnected their long handle by the junction plate 88 of freedom of movement, thereby make these cranked rod 86 interlocks.During contract fully, corresponding with either party cranked rod 86, the turning to 90 of supports of 87 butts of long handle side revolving body of above-mentioned cranked rod 86 is provided with one.Pushing is provided with two with 92 of supports are corresponding with two cranked rods 86 respectively, and the support of the length that both sides can engage perhaps is set.In the 3rd remodeling example owing to turn to 90 of supports and be provided with 1, so do not have the 1st problem of retrofiting the interference in the example, with its be installed in labeled door 16 upper surface where go up all no problem.Below, simple declaration is carried out in action to the routine pressing device of the 3rd remodeling, when be provided with turn to the revolving body 87 of the long handle 37 of the cranked rod 86 of support 90 sides with turn to when connecting with support 90, the opposing party's cranked rod 86 is passed in this action made its same action by rotating freely junction plate 88, make the revolving body 89 on the short handle that is arranged on two cranked rods 86 be fastened on pushing respectively with on the support 92, labeled door 16 is crushed on the doorframe 4.
The routine pressing device of the 4th remodeling that Figure 13 is represented describes again.In the pressing device of the 4th remodeling example, a cranked rod 94 only is set at the central portion of labeled door 16 upper surfaces.On the gyroaxis center of revolving body 98, push plate 96 is set and is used as the revolving body supporting member in mode free to rotate, and revolving body 98 is set respectively at the two ends of push plate 96, replace being arranged among the cranked rod 94 in the pressing device shown in Figure 5 the revolving body 40 of short handle side thus.More particularly be exactly that push plate 96 installs back in mode free to rotate in its each top ends and turns 98 from being installed in pivot on the short handle to the closing direction of labeled door 16 and open direction and extend.On the assigned position of the 1st upper ledge 12, be provided with to turn to and use support 100, and the pushing support 102 that engages with above-mentioned two revolving bodies is set on the assigned position of the 2nd upper ledge 14.Be arranged on 98,2 rackings that all connect with support 102 and carry out labeled door of revolving body at the two ends of the push plate 96 on the cranked rod 94 with pushing.Labeled door 16 when turning to support 100, cranked rod 94 and pushing with support 102 contract fully presses against peristome 2 sides with every cigarette.
Figure 14～Figure 16 represents another the relevant embodiment of pressing device with the blocking device of present embodiment.Wherein, Figure 14 is and the similar figure of Fig. 2 on expression labeled door top that Figure 15 and Figure 16 are the vertical views of the pressing device of another embodiment.
Have as Figure 14～pressing device 104 shown in Figure 16: pushing guide plate 106, it is installed on the labeled door 16; Pushing roller 108, it is installed on the 2nd upper ledge 14 and with pushing guide plate 106 and engages.Pushing guide plate 106 is outstanding towards pushing roller 108, has the snap-latch surface 109 that extends and engage with pushing roller 108 from a side direction door rear side in front of the door of labeled door 16.This snap-latch surface 109 has: the inclined plane, and its side in front of the door from labeled door 16 tilts to pushing roller 108 gradually towards the door rear side; Parallel surface, itself and above-mentioned inclined plane form continuously, and extend in parallel with the switching direction.More particularly, pushing guide plate 106 is formed by metal tabular component, on rostral components in front of the door, tabular component is tilted towards door rear lateral pushing roller 108 from a side in front of the door of labeled door 16, on door rear side part, be bent to form for open and close direction and extend in parallel shape.
With reference to Figure 15 and Figure 16 action is described.As shown in figure 15, before the full close position of labeled door 16, more particularly, before the head part in front of the door of labeled door 16 arrived fastening position, pushing roller 108 engaged with the inclined plane of pushing guide plate 106.Along with labeled door 16 moves (shown in arrow among Figure 15) again to fastening position, pushing guide plate 106 moves with respect to pushing roller 108, engage with pushing roller 108 in from the inclined plane of pushing guide plate 106 to the gamut of parallel surface and mobile.Thus, labeled door 16 leaves the 2nd upper ledge 14 sides.When labeled door 16 arrived complete fastening position, as shown in figure 16, pushing roller 108 engaged with the parallel surface of pushing guide plate 106, and labeled door 16 is pressed on the face of doorframe 4 reliably.
In the blocking device of above present embodiment, labeled door 16 arrives before the fastening position, pressing device 18 begins action, during closing this fully, produce moving resistance by pressing device 18, but because the effect of arrangements for speed regulation 30 with respect to labeled door 16, from assigned position P to fastening position the speed with speedup close, so can overcome resistance when mobile with the impulse force of closing, labeled door 16 is fully closed thus.
Therefore, because pressing device 18 works under complete closing state, so can cut off fully between labeled door 16 and the doorframe 4.
The present invention is not limited to above embodiment, can carry out various changes in the described invention scope of claim, and self-evident, they are also contained in the scope of the present invention.
For example, above-mentioned embodiment is illustrated the occasion that blocking device 1 is used for the labeled door 16 of sliding door type, but is not limited to labeled door, also can be used for the sliding door of other purposes.
