There is.

(Purpose of the invention) However, according to the previously proposed structure described above, the push/pull runners attached to the moving ends of each curtain are directly connected to the respective rack lines, so the opening/closing sliding movement length of each curtain is If there is a difference, the proposed structure cannot be applied, and therefore the scope of application is limited.

Therefore, an object of the present invention is to provide a curtain opening/closing device which can be effectively applied to curtains of series windows in which the opening/closing sliding movement length of each curtain is not uniform.

(Structure of the invention) In order to achieve the purpose, in the structure of the invention, a front curtain 2 having a short opening/closing movement length and a rear curtain 4 having the same long length are provided along the opening/closing movement direction. The front and rear curtains 2 and 4 are mounted on frames along the upper edges of the front and rear curtains 2 and 4 in a curtain opening/closing device in which the rear ends are fixed in a fixed position and the front ends move back and forth in the front and back direction to open and close almost simultaneously. Lines 16 and 26 are provided on the front side of the front and rear curtains 2 and 4 when they are in the closed position, and on the rear side when they are in the open position. , 26 are connected to the front curtain 2 when the front and rear curtains 2 and 4 are in the closed position.
The length l ₂ of the rear curtain 4 and the length l ₁ of the rear curtain 4 are projected forward by a difference △l, and the front projecting ends of these lines 16, 26 are parallel to the rear direction and correspond to the difference △l. The front end of the interlocking line 17, which is a long rod-like body, is connected and protrudes, and the front end of the rear curtain 4 is fixed to the outer peripheral position of the corresponding line 16, 26 in the closed position via the passive runner 20A. A follower runner 20D is provided at the front end of the front curtain 2, and a hole formed in the follower runner 20D is connected to the interlocking line 1.
When the interlocking line 17 is moved rearward, the hole of the follower runner 20D slides on the outer circumference of the interlocking line 17 and hits the joint at the front end of the interlocking line 17, and is moved rearward. Interlocking line 17
When moving in the forward direction, the hole of the follower runner 20D slides on the outer periphery of the interlocking line 17.
This curtain opening/closing device is characterized by having a structure in which it moves forward when it comes into contact with a stopper 17a at the rear end.

(Example) Hereinafter, the configuration of the present invention will be specifically described with reference to an example shown in FIGS. 1 to 9.

The opening/closing device of the embodiment includes two curtains in series that cover side windows of an automobile compartment, that is, a front curtain 2 that covers a front window 1 and has an opening/closing sliding movement length of l ₂ .
This is an opening/closing device for simultaneously opening and closing a rear curtain 4 covering a rear window 3 and a rear curtain 4 having a travel length of l ₁ , in which Fig. 1a shows the closed position and Fig. 1b shows the open position. Furthermore, the moving length of the rear curtain 4 is l ₁
is _{the difference △l(l 1 −}
l ₂ ) is longer.

By the way, a curtain rail 5 along the upper edge of the front window 1 and a curtain rail 6 of equal shape along the upper edge of the rear window 3 are fixedly installed in a straight line on the inner wall surface of the upper part of the vehicle compartment. , and the opposing ends of both curtain rails 5 and 6 are open on both sides of the cover 8 of the drive mechanism 7.

The shape of the curtain rails 5 and 6 is approximately L-shaped in cross section, and an upper line passage 9 and a lower line passage 10 are formed on the sides thereof, and at the bottom thereof, Spiral-shaped guide groove 11
are molded all the way through.

On the other hand, the drive mechanism 7 attached to the pillar 12 of the vehicle body is equipped with a geared motor 13, a transformer gear 14 driven by the motor 13, and an interlocking carrier pinion 15. , is configured to be stroke-slidingly driven by a transformer gear 14 while being held by a carrier pinion 15.

Therefore, the easy line 16 inserted into the line passage 10 at the lower stage of the curtain rails 5, 6
is a round bar wire body made of a semi-rigid resin material having slight flexibility, and has a flat surface cut off at the bottom thereof with a rack tooth 16a that meshes with the above-mentioned transformer gear 14. ing.

Further, at the front end of the rack line 16, there is an interlocking line 1 made of the same resin material with a small diameter and extending rearward inside the line passage 9 at the upper stage of the guide rails 5, 6.
7 are fixed to one body via a composite clamp 18, and the extension length of this interlocking line 17 is a length corresponding to the difference Δl between the moving lengths of both curtains 2 and 4, A large diameter stopper 17a is formed at its tip.

Incidentally, a plurality of locations on the upper edge of each curtain 2, 4 are tied to hanging rings 19 of four types of runners to be described below, and are held hanging therefrom, and the manner in which each runner is formed will be described below.

(a) Passive runner 20A (Figs. 2 and 3) This runner 20A is located at the front end of the rear curtain 4,
That is, it is attached to the moving end, and its shape consists of a sliding metal fitting 21 that holds the hanging ring 19, a roller 22 that slides on the guide groove 11 of the guide rail, and a clamp 23 that fastens the rack line 16.
The passive runner 20A is directly connected to the rack line 16 and moves as one with the rack line 16.

(b) Idle runner 20B (Fig. 4) This runner 20B is attached to multiple locations in the middle of each curtain 2, 4, and its shape is as follows.
The sliding hardware 21 and the roller 22 are integrally formed, so that the floating runner 20B can freely move along the guide rails 5 and 6.

(c) Fixed runner 20C (Fig. 5) This runner 20C is attached to the rear end, that is, the base end of each curtain 2, 4, and its shape is similar to that of the sliding hardware 21 and the guide rails 5, 6. A fixed metal fitting 24 that clamps and fastens the edge of the guide groove 11 is formed as a single unit, so that the fixed runner 20C is fixed to the guide rails 5 and 6 and does not move.

(d) Follow-up runner 20D (FIGS. 6 and 7) This runner 20D is located at the front end of the front curtain 2,
In other words, it is attached to the moving end, and its shape is one in which a sliding metal fitting 21, a roller 22, and a clamp-shaped eye 25 through which the interlocking line 17 passes are formed as one body, and thereby the following runner 2
0D can move freely along the interlock line 17, but after sliding relatively forward on the interlock line 17 and the eye 25 abuts the compound clamp 18, the rearward sliding of the lock line 16 The eye 2 follows the eye and moves backward.
After the runner 5 collides with the stopper 17a, it moves forward following the forward sliding of the easy line 16, and in this way, the following runner 20D moves to follow the easy line 16 with a play corresponding to the difference Δl. do.

Next, the operation of the opening/closing device of the embodiment configured as above will be described.

First, in the closed position of the curtain shown in FIG.
6a is driven and the rack line 16 starts sliding rearward, and at the same time, the passive runner 20A at the moving end of the rear curtain 4 also moves rearward.

However, the following runner 2 at the moving end of the front curtain 2
0D only moves relatively forward on the interlocking line 17 and remains stationary.

Next, when the rack line 16 slides backward by the difference Δl, the compound clamp 18 moves to the eye 25.
After hitting the curtain, the follow-up runner 20D also moves backward to become one with the easy line 16, so both curtains 2,
The moving ends of the geared motors 13 and 4 simultaneously reach the open positions A and B, and the power supply to the geared motor 13 is stopped by the operation of a limit switch (not shown) (FIG. 1b).

In addition, in the open position shown in FIG. 1b, when the closing operation switch is turned on and the transformer gear 14 rotates counterclockwise, which causes the rack line 16 to start sliding forward, the rear curtain 4 simultaneously moves forward. However, the front curtain 2 is connected to the interlocking line 1.
The stopper 17a of No. 7 is the eye 2 of the follower runner 20D.
Since the curtains 2 and 4 begin to move forward after passing the play stroke until they collide with each other, both curtains 2 and 4 reach the closed position at the same time, and the easy line 16 stops.

Since such opening/closing operations are performed by operating the semi-rigid rack line 16 sent by the rack, the passive runner 20A and the follower runner 2
Even in curtains 2 and 4 where there is no risk of positional deviation occurring in 0D and whose opening/closing sliding movement lengths l ₁ and l ₂ are different,
Can be opened and closed smoothly.

By the way, the configuration of the above-mentioned embodiment is a structure applied to opening and closing two curtains in series, but it can be similarly applied to opening and closing three or more curtains, for example, as shown in FIG. 10. As shown, after connecting the three side window curtains on each side of the passenger compartment and the rear window curtain, and extending the easy line 26 endlessly around the four circumferences of the passenger compartment, For each curtain that is driven by a similar installed drive mechanism 27 and has a short movement length, a single easy line can be used if interlocking lines are arranged in parallel according to the respective size differences. It is possible to open and close multiple curtains.

(Operations and Effects of the Invention) As described above, according to the curtain opening/closing device according to the present invention, the front and rear curtains whose opening/closing sliding movement lengths are not uniform can be moved by driving the operating stroke of a line made of a long rod-like body. At the same time as opening and closing the
Curtains whose travel length is less than the maximum travel length are configured to be driven on interlocking lines made up of long rod-like bodies with lengths corresponding to each difference in travel length via runners that follow with play. Therefore, front and rear curtains having different opening/closing lengths can be simultaneously opened and closed reliably and smoothly, which has the effect of increasing the reliability and applicability of the curtain opening/closing device.
