Abstract

One curtain includes a rail and some tow that suspends in midair from a rail of certain rigidity, prop up rail (1) by two or more adjacent terminations hinged rail portion of hinge bracket, be mutually straight line at them between the rail portion of adjacency like this and be in when stretching out the position entirely and be parallel to each other foldingly when being in full folding position, can pivot.

Description

Curtain

A present invention and a rail that includes certain rigidity, some flexible tow, belt and similar bands under a rail suspention.

In use, a rail of this kind curtain is contained in the top of door opening and window, tow can be crossed door opening and window and be sagging like this, the curtain of many kinds of different types is in common knowledge for everybody, and one of them example is my early stage Britain application, discloses with series number 2180151A, in this application, some tow are contained on the slide, and slide is again by on the guide rail of rail, and curtain also has some relative tow self to be fixed on tow on the slide.

By laterally opening from maximum of moving sliding base (pulling just is connected in the tow on the slide) curtain, promptly tow is positioned to and crosses over whole window frame, and to minimum, promptly the tow in the part window frame can be unblocked.

Nature, the length of rail is equivalent to the maximum transversal of curtain at least opens, and therefore concerning door opening, its rail length is required to be about 1 meter, and the not special difficulty of the rail of producing this length, it is problematic that to be curtain take back in the shop of buying may have a few inconvenience.

Therefore the present invention seeks to eliminate or alleviate above-mentioned defective.

It has rail and the some flexible tow under a rail suspention that includes certain rigidity according to the present invention, wherein props up rail and is made up of two or more rail portion, connects together with hinged in its adjacent end.Like this, these adjacent rail portion can be mutually the position of straight line and be mutually between the position of rolling over choosing moving around pivot shaft at them.

The characteristics of other recommendation of the present invention and advantage become more obvious from following narration and following claim.

The present invention will and will further narrate with reference to the accompanying drawings by example.

Fig. 1 shows the position that is in full extended state according to an embodiment of curtain of the present invention;

Curtain in Fig. 2 presentation graphs 1 selects the position of state at full folding;

Fig. 3 is the local enlarged perspective of the curtain to Fig. 1 when being in the part folding and selecting state;

Fig. 4 is the local amplification view of the curtain of Fig. 1 along hatching IV-IV;

With reference to accompanying drawing, the curtain shown in the figure includes a rail 1, and from a tow 2 of the some pearls of rail suspention, a rail 1 is made up of two

rail portion

3 and 4, and this two rail portion is hinged by a hinge bracket.

Each

rail portion

3 and 4 has two closed slides 6 and 7(to see Fig. 3).Tow 2 on each

rail portion

3 and 4 is arranged to 2 cover curtains 8 and 9 and is contained in (not shown) on the slide, this slide moves on the corresponding guide rail length of double-head arrow A indication, and each curtain 9 all is fixed on 9 corresponding positions of an other curtain of track 1.

Tow 2 includes the pearl tow that certain-length flexible silk beam material polyphone pearl forms.

Hinge bracket 5 is shown in further detail in Fig. 3, and it looks and is generally a U-shaped spare, is linked to be holistic connecting plate 5c by one cochain sheet 5a and following chain sheet 5b are linked up.Hinge bracket 5 has a pair of lug that extends longitudinally 10 in each termination, and the recessed petiolarea 11 of

rail portion

3 and 4 passes a pair of lug 10 and forms rotating assembling with bolt 16 successively, like this,

rail portion

3 and 4 can form fully as shown in Figure 1 stretchs out, and can pivot, wherein

rail portion

3 and 4 can be mutually straight line and be in the state that selects of rolling over fully as shown in Figure 3, wherein generally folding choosing in parallel to each other of

orbit portion

3 and 4.

Be at rail 1 and stretch out the position fully, the termination of

track

3 and 4 vicinity is in syntople, and its upper surface leans against the inner face of connecting plate 5c, and this has just guaranteed that a rail 1 has enough intensity.

Referring now to Fig. 4, a pair of hole 12 is in line opened and is being extended lug 10 and at the left and right sides of hinge bracket 5 center lines, and termination near

rail portion

3 and 4, two through holes 13 are opened the approach end in

rail portion

3 and 4 successively, (when rail 1 is in when stretching out the position fully) through hole 13 of each rail portion is aimed at the pair of holes 12 of cochain sheet, in order to make rail 1 keep certain rigidity when the deployed position fully, a pair of locking pin 14 inserts in the pair of holes 12 and through hole 13 of aiming at, pin 14 is tightly by being placed in hole 12 and the through hole 13 like this, pin 14 is easy to pass plastic presser plate 15 simultaneously, when plastic presser plate 15 is embossed on the chain sheet, the enlarged head 14 of pin 14 ' be embedded in the plastic plate.

More than just narrate invention by example, the various modifications of the foregoing description only otherwise departing from the scope of the invention defined by the claims all allows, for example, the chain sheet can replace with the hinge that includes two thin slices, and each thin slice is all linked the respective track part, and this two thin slice is hinged together mutually.

Claims

1, a curtain includes a rail and some some flexible tow under a rail suspention of a suitable rigidity, wherein prop up rail and have abutting end hinge joint rail portion together by two or more, like this, these adjacent rail portion are mutually linear position and the two at the two and are mutually the folding bit selecting and pivot between putting.

2, curtain according to claim 1 when rail portion is mutually linear position, also includes the locking device of rail portion.

3, according to claim 1 and 2 described curtains, wherein the rail portion of adjacency all is hinged on the hinge bracket, and this hinge bracket is connecting together between this two rail portion.
