Runner devices arranged within the hanger rail are rotatable irrespective of the attitude of a panel body and can be smoothly moved with the hanger rail. In addition, the panel body can be simply moved at a branch path, a bend in the path and the like through upper and lower guide rollers and a controller device for the runner devices. Furthermore, the panel body in its horizontal attitude can be closely positioned with respect to a fixed wall.
Description
The present invention moves, large space can be isolated into the moveable partition board in any space about a kind of guide rail that can set up on the ceiling.
In large-scale exhibition such as emporium, hotel, banquet room, the larger area stateroom is arranged, in the time must being arranged to small-scale banquet room or conference room to them, just can use moveable partition board, large space is separated into the space of suitable size.Moveable partition board is by setting up the hanger rail that a section becomes the C font on the ceiling, and suspending the diaphragm body that can move freely on this hanger rail in midair and constituting, the hanger rail groove is arranged on downwards in the above-mentioned hanger rail, the carriage of a pair of car-type is housed in this hanger rail, and this carriage is connected by suspention double-screw bolt and aforementioned barriers main body.
On the other hand, in order to adapt to all changes of diaphragm body configuration, form many turnouts on the hanger rail, dividing plate itself is no matter can both move freely on which turnout.That for example, thought way on above-mentioned carriage has a clear 54-12 81 44 of Japanese Unexamined Patent Publication No.In addition the main body of plate is carried out the practical new case of improved Japan and announce clear 52-55 25 1.
Yet moveable partition board requires with fixed wall same performance is arranged in sound insulation value and aesthetic in recent years, thereby aforementioned barriers can not adapt to maximization and overweight requirement, many particular problems below existing:
1. the carriage that sets in guide rail makes the bigger frictional resistance of generations between the sliding mats between this carriage and the hanger rail because overload of power, overslaugh dividing plate level and smooth mobile.Particularly when carriage arrived the sweep of hanger rail or bifurcation point, it is big that the moving resistance of carriage becomes, and hinders the dividing plate mobile working.
The new case communique of above-mentioned practicality represent like that, for locating moveable partition board at hanger rail bifurcation point etc., on the main body of dividing plate, be provided with control device, by the suspention double-screw bolt, above-mentioned tourelle is done transportable the connection with the plate main body, owing to the plate main body frictional resistance is arranged, this control device can not move freely, on the contrary overslaugh moving freely of dividing plate.
3. in addition, the main body of plate must be to be in vertical position for ground when forming partition wall, yet because the main body of plate maximizes, produces sometimes.
4. because the main body of plate is excessive, overweight, in construction and maintenance, encounter difficulties.According to this point, the assembled part of particularly above-mentioned tourelle and control device and the repairing of control device are very difficult, and it is also impossible to repair rapidly when producing fault.
In view of above variety of issue, main purpose of the present invention provides a kind of turnout and crooked road etc. at hanger rail Anywhere can both the slick and sly moveable partition board that moves.
Specifically, its objective is: (a) reduce the frictional resistance of carriage as much as possible, also can move smoothly even make when in the hanger rail turnout and crooked road being arranged.(b) because of control device can move with respect to the very little sliding-frictional resistance of plate main body, simultaneously, diaphragm body can be correctly, be placed vertically good position.(c) carriage, control device and diaphragm body all have the structure that is easy to load and unload, and are easy to construction, repair and maintenance.

Figure 15, Figure 16 represent the side cut away view of other control device example.
Figure 17 represents the sectional drawing of other example of control device.
Figure 18 is the action specification figure of control device among Figure 17.
Fig. 1 represents the configuration in the hanger rail, and the carriage that moves in this hanger rail.Carriage (hereinafter to be referred as slide block) 10 is made of slider body 11, shifting roller 12,12 and critical pieces such as lower tracks wheel 13,13 and upper track wheel 14,14.
Shifting roller 12,12(i.e. 3 pairs of 6 rollers) be contained in the left and right side of slider body 11, can rotate freely by axle 11c, 11d(11d), simultaneously, 6 rollers can contact at grade.
As shown in Figure 3, be provided with bifurcation point S in hanger rail 30 fixing places, near the top bifurcation point S has been laid and can have been taken turns 14, the 14 suspention track 34(that contact referring to Fig. 2, Fig. 3, Fig. 4 with upper track).Suspention track 34 has along the suspention track 30 of fork and slowly crooked orbital plane 34a.This orbital plane 34a can determine the mobile alignment of slide block 10, that is, the upper track of slide block 10 wheel 14,14 rolls along suspention orbital plane 34a, so whole slide block 10 also changes the route of oneself along suspention track 34.
One group of moveable partition board is that the slide blocks 10,10 that are located at 2 suspention double- screw bolts 21,21 on the 22a of its upper surface and supporting these two suspention double- screw bolts 21,21 respectively by a plate main body 22, highlightedly constitute.
When the direction of advance of moveable partition board is K from Fig. 2
1When direction moved to the suspention track on the left side, the operator can be by promoting dividing plate 22, and the slide block 10 in the place ahead meets arrow K
1Direction near bifurcation point S.Because increasing gradually in the fork part between the moving track face 33,33 of suspention track 30, so can not determine the shiftable haulage line of slide block 10 by lower tracks wheel 13,13 apart from d.For this reason, by track 34 restriction upper track wheels 14,14, and guide whole slide block 10.That is, as long as the upper track in the place ahead wheel 14 contacts with the orbital plane 34a of track 34, its upper track takes turns 14 will be to the direction of arrow K of Fig. 3
2Rotate, can move along orbital plane 34a simultaneously, the front end of slide block 10 can change direction (seeing the dotted line of Fig. 3) left.
At this moment, just producing with suspention double-screw bolt 21 on the slide block 10 is the center, by the rotating torque that centripetal force causes, is easy to change the advance route of slide block 10.So, when the advance route of slide block 10 changed, slide block 10 was done relative rotation with respect to diaphragm body 22, yet because the main body 22 of plate is passed through thrust bearing 11b support slipper 10, so both relatively rotating can both be slided by rolling friction.
Therefore, slide block 10 is by bifurcation point S the time, and lower tracks wheel 13,13 is moved orbital plane 33,33 guidings again and moves.
And, when each slide block 10 when changing route, shifting roller 12,12 on one side, cross the peristome (seeing the chain-dotted line of Fig. 3) between the moving track 33,33 obliquely, having 2 mobile wheels 12 at least in the mobile wheel 12,12 of on one side 3 is often can contact with all-moving surface 32, so, even in this situation, slide block 10 also can keep horizontal level, and slide block 10 just can pass through bifurcation point S sleekly.But under the very little situation apart from d between the moving track 33,33, shifting roller 12,12 is 3 pairs of 6 wheels not, use as long as there are 2 pairs of 4 wheels also can have no overslaugh ground.
Among Fig. 4, as slide block 10 relative arrow K
4Direction when changing route to the right, can will be bonded together to the track 34 of right bending and the upper rail guide wheel 14,14 that rotates in slide block 10 upper right.In addition, track 34, if can give on perpendicular to the direction of direction of advance with upper track wheel 14,14 just enough to the centripetal force of right, so that the upper track roller 14,14 on the left side above the slide block 10 rotates (seeing the double dot dash line among Fig. 4), be joined together with the track 34 that is arranged on the left side again, also can obtain same effect.
As shown in Figure 5, the height by selected track 34 is A
1, A
2, the setting height(from bottom) of upper track wheel 14,14 is a
1, a
2, can select both to have or not joint, that is, can select the advance route of slide block 10 to have or not change.For example, for highly being A
1 Track 34, with setting height(from bottom) a
1, a
2Two upper track wheel 14,14 engage, can change so have the advance route of two kinds of slide blocks 10,10 of upper track wheel 14,14, and for the track 34 that highly is A, with setting height(from bottom) a
1 Upper track wheel 14 do not engage, and only with setting height(from bottom) a
2 Upper track wheel 14 engage, therefore, have only the slide block 10 of the rail wheel 14 on latter top just can change advance route.
At former and later two end faces of slide block 10, as shown in Figure 6, can load onto two pads 15,15.If the effective thickness of pad 15,15 is n, the thickness of plate main body 22 is t, when the length of the fore-and-aft direction of slide block 10 surpasses m, and m+2n＞1.According to this formula, because the not contact of main body 22,22 of two boards, so can prevent the breakage of plate main body 22,22 effectively.
According to above explanation, front and back on slide block are equipped with the upper track wheel respectively, and between slide block and suspention double-screw bolt owing to disposed thrust bearing, in the time will changing the advance route of slide block, will produce effective rotating torque that can change the slide block direction, simultaneously, energy will be between track and upper track roller, and the frictional resistance between slide block and the suspention double-screw bolt becomes rolling friction from sliding friction, therefore, the moving resistance of whole slide block has just diminished, even the heavy moveable partition board of benzene is arranged, also can change its advance route at an easy rate.This device has this good effect.
Fig. 7, Fig. 8 have represented to be arranged on the control device 40 on the main body 22 of plate.This control device 40 has sleeve pipe 44, main element 41, suspention roller 42, rail wheel 43,43.
Main element 41 has the screwed hole 41a of individual its middle body of up/down perforation, and the pin thread 44b of sleeve pipe 44 screws in it.In main element 41, be provided with the fixed axis that connects left and right directions, the suspention roller 42 of taking turns for two pairs 4 is housed two ends ...The outer circumference surface part of suspention roller 42 is outstanding above main element 41.
On main element 41, rail wheel 43,43 is housed respectively all before and after it.Rail wheel 43,43 clips sleeve pipe 44, leans against above the main element 41.This rail wheel 43,43 is positioned on the center line of fore-and-aft direction of main element 41.
As shown in Figure 1, the suspention double-screw bolt 21 that screws in 44 li of sleeve pipes can rotate sagging freely from slide block 10 by thrust bearing.
It is the slotted hole 53 at center that a longitudinal centre line with track component 52 is arranged near the end of a side on above-mentioned track component 52, and the both sides of slotted hole 53 form track contact surface 52a, 52a.Because of setting the width D of slotted hole 53
1Diameter D than rail wheel 43
2Slightly bigger, the vibration of left and right directions that therefore can control the rail wheel 43,43 on track contact surface 52a, the 52a is in very among a small circle.But, in order to allow rail wheel 43,43, and in slotted hole 53, rotate, thereby will determine the position of its height along slotted hole 53.
Track contact surface 52a, 52a with supported underneath by suspention roller 42, and the weight of plate main body 22 is by track component 52, but dispersion pressure is on each suspension wheel.And rail wheel 43,43 rotates along slotted hole 53, so control device 40 in the length range of slotted hole 53, can move forward and backward.Therefore, the main body 22 of plate can be moved as shown in Figure 9.
General large-scale moveable partition board is operated by two operators.With the plate main body 22 of playing downwards on the suspention track H, the H that are parallel to each other, with direction of arrow J
1, J
2Give respectively to promote, because the difference of operator's thrust size, plate main body 22 is with respect to direction of advance some inclination (as double dot dash line 22a of Fig. 9) slightly.At this moment, because control device 40 can freely move,, suspention double-screw bolt 21B arrives 21B in track component 52 so being easy to change its position
1, change and other suspention double- screw bolt 21A
0, 21A
1Distance.Therefore, plate main body 22 can be along with operator's promotion, on one side its position of appropriate change, move sleekly on one side.
This means, the main body 22 of the plate that down plays on the suitably crooked suspention track H be rotated frequently.For example, in Figure 10, by dextrad arrow J
3The plate main body 22 that direction is advanced is led H by the suspention rail of Y type fork, to arrow J
4And J
5Direction move in turn, so can do the correct motion (as double dot dash line among Figure 10) of keeping to the side with respect to wall surface W.
In addition, above-mentioned control device 40, its movably scope be limited in the scope of slotted hole 53, utilize sleeve pipe 44 just can freely regulate its height, the decision position.But when inserting control device 40 in the track segments 52, the insertion mouth that does not illustrate on the application drawing, be located at jointly the bottom surface of guide rail 52 and framework 55 above.
In the above description, the weight of the main body 22 of plate can be by increasing the number of its suspention wheel arbitrarily when too benzene is heavy, for example, 4 suspentions of 2 couple roller 42 of control device 40 is become 3 pairs 6, or 4 pairs 8, the weight that each suspends the plate main body 22 of roller 42 loads in midair just can be reduced.
And control device 40 is when slinging a plate main body 22, and two under hanging are suspended in midair in the double- screw bolts 21,21, if corresponding with one just enough, certainly also can be all corresponding with two.
According to above explanation, this device has following excellent results, promptly because suspention roller and rail guide wheel independently are housed on the main element, in order to prevent beating of control device left and right directions, transfer frictional resistance to minimum rolling friction, so the motion of control device can be carried out sleekly, can improve the operating characteristics of whole moveable partition board.And and the binding of suspention double-screw bolt undertaken by sleeve pipe, thereby be easy to determine the position of control device, make connection work also simple especially.
Figure 11 is other examples of implementation of expression control device 40, and a screw-in in a pair of suspention double-screw bolt 21 under slide block 10 hangs hangs in the piece 56.On this hangs piece 56, direction up becomes a convex, and the thickness direction of plate main body 22 almost is in centre bit and is equipped with peak, and both sides tilt gradually, forms a flexure plane.
As shown in figure 14, now by guide runner 10, the movable plate main body stops then to certain position, hangs piece 56 and is in the center of hanging lower member 52A, promptly is in the center of the thickness direction of plate main body 22, this plate main body 22 can be hung down.Therefore, plate main body 22 with hang piece 56 and hang lower member 52A and can shake the center as the straight line that line contacts, and this straight line is almost just on the median plane CP of plate main body 22.Therefore, when the center of gravity G of plate main body was on median plane CP, plate main body 22 just often can be hung down with correct vertical direction, fully less than with the anxiety of vertical plane inclination.
Figure 13 is formation plane on hang piece 56, with hang the upper central part 52C that hangs lower member 52B that piece 56 joins, on the transverse direction of diaphragm body, it is also feasible to form downwards spill, at this moment, is too and hangs piece 56 and hang lower member 52A makes straight line on the transverse direction of plate main body 22 line and contact, because the contact position that can set both almost is in the center of plate main body 22 thickness directions, therefore, identical with last example, this plate main body 22 vertically can be hung down.
As Figure 15, shown in Figure 16, hang piece 56 by rotor block 43A, 43B, also plate main body 22 can be hung down.Promptly as shown in Figure 11, rotor block 43A, 43A are placed on the center of the thickness direction of control device 40,, resemble and form than major diameter Figure 15 simultaneously because with the lateral center part of rotor block 43A, 43A.Hang piece 56 and hang on the median plane CP that lower member 52B nearly all is in plate main body 22, can make its do the some contact by rotor block 43A, 43A, so just plate main body 22 vertically can be hung down.As shown in figure 16, rotor block 43B is formed simple cylindrical shape, it is good that the top 52C that hangs lower member 52B is formed a spill downwards.
When on hanging piece 56, having rotor block 43A or 43B, owing to hang the 57 one-tenth slotted holes of through hole above the lower member 52B, length according to through hole 57, hanging piece 56 can relatively move for hanging lower member 52B, if so will have such rotor block 43A or the control device 40 of 43B, be contained in either party of the front portion of plate main body 22 or rear portion, control device 40 just can change these two distances between the suspention double-screw bolt.
According to above explanation; this device has following excellent results: owing to hang piece almost is that originally hang down the plate master at the center that is in plate body thickness direction; so the plate main body is under stable state when static; the center of the thickness direction of the upper part of plate main body and the center of gravity of plate can be on the same vertical plane; at this moment; the plate main body can correctly vertically be hung down; even so when many blocks of plates are arranged side by side; its surface does not have irregular phenomenon yet, forms mobile dividing plate through regular meeting with in good order neat state.
Figure 17 is the sectional drawing of expression another control device 40 of the present invention.This control device 40 is made of the main element 41 and the track 60 that moves about.
