With regard to the curtain leaf, the extension that arches upward on curtain leaf one end in fact with the corresponding edge of curtain leaf at grade, and on opposite end, only open an osculum so that be made into a rectangular cross section with the passage of the extension coupling of arching upward, thereby such problem can take place, when the console switch device, derailing switch slides along maze path will often change direction, and in the coupling passage, owing to be straight, be provided with circular arc, so or many obstacles can take place, perhaps can weaken the motion of derailing switch.

These inconvenient the applicant take to heart, and the solution that him is proposed not only will overcome concrete shortcoming, and will solve the problem that influences derailing switch termination curtain leaf.

Say that more specifically the present invention concentrates strength on improving the curtain leaf of reversible derailing switch, make two termination curtain leaves of said derailing switch have suitable terminal.

The feature or the improvement of first novelty are, the inner surface that constitutes the extension that arches upward of coupling element at curtain leaf one end is the indent bending, rather than it is flat, as existing curtain leaf, this indent curved surface and the evagination curved surface complementation that forms fin (or wing) at the curtain leaf other end, this outer convex surface is originally the border that is located at the passage of the curtain leaf other end at a lateral confinement surely, this passage and said extension coupling.The curved surface of these two complementations can provide a hinged effect and motion to the curtain leaf, makes the curtain leaf can not be subjected to the influence that the path changes when maze path moves.

Said passage is limited by a fin that arches upward (wing) at opposite side, its free end trends towards restraining and rests on the formed enough big step of this extension that arches upward, the function of a hook so just is provided, makes us that a sealing that does not have the slit can be arranged, whole room can be dark fully.

In addition, uppermost and nethermost outer curtain leaf all terminates on the oblong channels of only opening osculum, can be equipped with air flow partition device or joint on it, damping supporting can be provided, and seamless sealing can be provided.

As from scheming to go up as seen, propose as an improved shutter case that reverses, panel 1 at the bottom of it comprises, one cover a panel 2 and an offside panel 3, and all these plates all can add enclosing cover or ornamental panelling 4 separately.

But reverse switch device composite member itself has pair of side plates 5, and side is shaped on maze path 6 separately within it; Polygon shaft 7 is located at and is used for coiling/unwinding derailing switch between said two plates 5; Said at that time axle 7 is by manual or motor-driven, thus rotation pinion and rim gear wheel 8, and the latter drives curtain leaf actuator by annex or the joint element that is contained in said curtain end of blade again.Said little ring gear, rim gear wheel, drag element and curtain leaf itself all is a part of derailing switch monolithic composite member.The form that drags element that engages with curtain end of blade annex is a special pinion, is contained on the axle 9.

In maze path 6, the import of blind blade or derailing switch is corresponding to label 10, and outlet is corresponding to label 11, and the following vertical guidance part of formation maze path extension is corresponding to label 12.

Based on these characteristics, installed inside at each side panel 3 has a pair of transverse slat 13, one last, one following, each transverse slat is provided with two pairs of wings 14, each is to passage 15 of wing one-tenth, and the passage 15 of last lower cross plate faces one another, so that installing plate 5 is just installed derailing switch monolithic composite member slidably.And, the window 17 that angle or inferior horn respectively are provided with a groove 16 and are communicated with groove on each side panel 3, its effect will be explained below.

The bottom of plate 5 is provided with fin 18, and its effect also will be explained below.

The present invention also has a feature mainly to be, it adopts one to be prismatic peculiar part 19 totally, the big surface of said part 19 is provided with many grooves 20, can cooperate with the protuberance 21 on the housing wall inboard that limits guidance part 12, therefore said part 19 can accurately be received within the housing, and the upper end of said part 19 has an extension or the wing 22 to extend through window 17 and be received within the groove 16 on the side panel 3.Like this, guidance part 12 just is connected on the side panel 3, and part 19 usefulness screws are fixed by the hole that faces one another 23 and 24 that is provided with on the extension or the wing 22 and on the bottom of groove 16.

At the other end of said part 19, also be on top, be provided with a groove 25 and can be used to admit fin 18 on the plate 5.This means, in case part 19 is installed between the guidance part 12 of casing and the side panel 3 and when being fixed on the casing as mentioned above, the derailing switch composite member just can module form be mounted, as long as plate 5 is slided along passage 15, fin 18 is received within the groove 25 and is inserted through the hole on the said fin 18 and is fixed with screw, this screw also by isolating the hole on the protuberance 27, is isolated protuberance 27 and is located in the passage 28, and purpose is for import 10 of setting up maze path 6 and outlet 11.The both sides of passage 28 are by camber slightly and open crooked partition 29 limited boundaries, guide corresponding curtain leaf 30 during with convenient curtain leaf 30 upper and lower slips.

At last, part 19 also is provided with a groove 31 and is used for engaging partition 32 on the guidance part 12.

As seen from Fig. 5,6,7 and 8, creationary curtain leaf 101 is hollow and rectangular, at the one end or have on one side one with respect to two sides and off-centered extension 102, form an enough big step 103 thus, the final elbow that forms an inside rounding of said extension becomes a kind of hook 104.This part and step 103 and extension begin to locate 102 interior surface opposing and curve inwardly.

There is an opening 105 on the other end of curtain leaf or limit between two wings 106 and 107, the wing 106 is arcuation, and the wing 107 is to become arcuation by an extension to the interior curve of side plate 108, the outer curve of the said wing 107 and concave surface 109 complementations, when derailing switch cuts out, both shapes are worked in coordination, as shown in Figure 7.

According to the feature of above-mentioned curtain leaf,, just can constitute derailing switch, as shown in Figure 8 as long as with a plurality of curtain leaf interrelated ground couplings.

Hook on the curtain leaf 101 104 just can be finished said coupling operation by 105 insertions of the opening on the adjacent curtain leaf relative edge.Because the special shape that both wings 106,107 and opening 105 have, hook 104 just is received within the corresponding passage 110, so that when attempting separating these two curtain leaves, hook 104 can couplings on the wing 107 and prevent said possible separation, said coupling is also because the free margins on the wing 106 fastens in the outside of said hook 104 or forms on the extension 102 of a part of said hook is guaranteed.

When the curtain leaf is closed or is overlapped, work in coordination and are accurately stacked in complementary surface on the wing 107 and concave section 109, free margins on the wing 106 equally accurately cooperates with step 103, thereby can prevent that light is not subjected to any restriction by also derailing switch being moved freely.

Constitute last curtain leaf 101 ＇ and the following curtain leaf 101 of derailing switch "; except having the coupling passage latter, the former has the hook; the both is provided with the outer tunnel 111 that can control at oral area; so that the part that comprises according to derailing switch is used for admitting and fixes a joint or air flow partition portion so that along isolated sealing of upper and lower part contact area formation.

With regard to the final variation of curtain leaf, as from Fig. 9,10,11 and 12 as seen, in the time of in derailing switch is received within maze path, it obtains a curve shape, and at this moment the angle between two adjacent curtain leaves is about 127 °.In this case, the curve of hook 104 can be fully and the curve fitting of the inflexed wing 107.See A among Fig. 9 for details.In contrast, when two adjacent curtain leaves hung mutually, the effect of dragging between the hook 104 and the inflexed wing 107 will obtain an eccentric effect, and a torque will be applied on the curtain leaf, and it is rested on the both sides of guide groove simultaneously.

With hook 104 opposed end or limits, one opening 105 is arranged between its both wings 106 and 107, the wing 106 is straight, and the wing 107 is made of aduncate extension on the side plate 108, outer curve on the said wing 107 and concave surface 109 complementations, when derailing switch cut out, both worked in coordination, as can be seen from Fig. 9.

Figure 14 and 15 illustrates the decomposition view that is contained in the manual driving device 50 in the casing; Obviously this composite member has a manual drives reducer 54 and a bi-directional brake 55.

Figure 16,17 and 18 illustrates the manual drives reducer that the composite member by four separator pinions 56 that the coplanar axle is housed constitutes, its unique function is that the drive rod 51 and the central compartment of manual drives composite member are opened, the number of teeth of said drive pinion is 10 and be 12 to two outside pinions to two central pinion, and they do not make the speed of rotation reduce.Slow down basically from becoming the bevel gear of 12 whole teeth and the rim gear wheel of corresponding 26 teeth with last separator pinion.Become whole one first drive pinion 59 that has with the rim gear wheel 58 of this taper,, be used for driving the curtain leaf that constitutes derailing switch thereon with axial restraint but can one first driving pinion 60 be housed integrally rotated mode.

First drive pinion 59 is required to transmit motion on second drive pinion 61, with axial restraint but can one second driving pinion 62 be housed integrally rotated mode, is used for driving the curtain leaf that constitutes derailing switch on second drive pinion.This motion transmission between first drive pinion 59 and second drive pinion 61 is to become the first whole adapter ring tooth axle 63 by one with interpleural axle 7 to finish with the second adapter ring gear 64 that it meshes.

The brake 55 of two-way conventional version is made of the hollow shaft 67 of a cover tripping spring 65, a C shape, a checking cylinder 66 and a braking shaft coupling 68.See Figure 15.

Figure 19,20,21 and 22 illustrates the motor driver that is made of traditional asynchronous AC motor 69, and its axle 70 terminates on the motor pinion 71.This motor pinion 71 is plugged between two first order planetary gears 72, and and first order planet rim gear wheel 74 become whole pinion 73 and be plugged between the second level planetary gear 75; Become whole pinion 77 with second level planet rim gear wheel 76 and then mesh with motor-driven rim gear wheel 78, this rim gear wheel 78 becomes whole and coaxial rotation with first drive pinion 59 and first driving pinion 60.Second level planetary gear is contained on the axle 79 of planetary gear retainer 80, and the protuberance 81 of fixed retainer periphery just can prevent that retainer from rotating.The planetary composite member of the first order is identical therewith; For clarity, corresponding planetary gear retainer does not illustrate.See Figure 21.

In the corresponding groove 83 of side plate 5, to hold several stop blocks 82, to its objective is whether derailing switch exists in each guide groove 6 in order detecting.See Figure 13,19 and 21.

The drive unit operation is as follows: the user rotates the crank throw handle in a direction or another direction, so that by being contained in a pair of traditional bevel pinion (not shown) in the crank throw handle casing 53, transmit motion on the drive link 51, this drive link 51 is attached on the housing in the brake coutact 68 rigidly and rotatably.

Become whole with said brake coutact 68 and rotatable C shape hollow shaft rotates a cotter pilotage that is plugged in the first inboard separator pinion 56 of axle, with lug free spring is pulled to inside simultaneously, this spring is enclosed in the elastic tube and forms brake spring composite member 65.Motion just is passed to separator pinion composite member 56, bevel pinion 57, conical ring gear 58, first drive pinion 59 and first and drags pinion 60 like this, and second drag pinion 62 and accept to rotatablely move by first drive pinion 59, the first adapter ring gear 63, the second adapter ring gear 64 and second drive pinion 61, sees Figure 16.

At last, drag the two ends engagement of pinion 60,62 and curtain leaf, they are slided along labyrinth guide groove 6, thereby derailing switch is moved.When not moving, derailing switch should be braked, and this is because the cotter pilotage in the first separator pinion 56 can trend towards making the spring and the lug that form brake spring composite member 65 to flick to inside, in the time of in being accommodated in checking cylinder 66, because its diameter expansion can hinder its rotation.

This bidirectional braking device 55 will no longer describe in detail, because it extensively is used in the shutter industry and is known by the expert of this respect.

With regard to motor driver, motor 69 is produced moves through motor pinion 71, first order planetary gear 72, first order rim gear wheel 74 and its pinion 73, second level planetary gear 75, second level rim gear wheel 76 and its pinion 77, in either direction rotation is sent to by motor-driven rim gear wheel 78, send first drive pinion 59 and first again to and drag pinion 60, this two pinion becomes whole and coaxial rotation.As for second motion that drags pinion 62, with top similar, undertaken by the first adapter ring gear 63, the second adapter ring gear 64 and second drive pinion about the said mode of manual driving device, see Figure 20,21 and 22.

When stopping, derailing switch is lived with a traditional bi-directional brake braking that is contained in the motor.
