Description
Technical field
The present invention relates to a kind of curtain, more particularly to the roller shutter that a kind of cord can be scrolled up or put down downwards, more specifically
Be be related to it is a kind of need not just can be by cord is rolled and is put down rolling screen without pull rope using drawstring.The present invention also provides a kind of above-mentioned nothing
The manufacture craft of drawstring roller shutter.
Background technology
Curtain both can have good decoration functions again with sunshade, heat-insulated, dust-proof, be the indispensable articles for use of household office, one
Warm romantic living environment or working space, it is inseparable with the ingenious collocation of curtain.The species of curtain is various, there is folding
Curtain, roller shutter, wooden louvres, Roman shade etc., roller shutter due to it is specious it is succinct, sound construction is durable, simple to operate
Feature, thus be used widely in household, hotel and dining room.Roller shutter according to curtain material it is different be divided into again bamboo roller shutter and
Through resin processed cloth roller shutter, bamboo roller shutter due to it is succinct it is free from vulgarity, simple and tasteful, with having literary or intellectual fame breath and green,
Thus deep to be welcome by European ＆ American Market, the curtain that China exports every year, bamboo roller shutter occupies very big ratio.But either bamboo roller shutter
Or cloth roller shutter, is essentially all that one end of roller shutter is fixed on into roller shutter to put, roller shutter is arranged with drawstring, pulls drawstring to adjust
The lifting of roller shutter, because drawstring is exposed in curtain side, if children are at play, drawstring is accidentally wound into neck, the drawstring
Then a rope sling can be formed by traction, so that neck of child has the danger strangled；In recent years, American-European countries is drawn being set on curtain
Increasingly stricter standard has been put into effect in the limitation of rope, and in view of this, those skilled in the art have developed much without drawstring knot
The curtain of structure, but these curtain without stretching wire are substantially setting spring winding apparatus, this structure on curtain rod and not only tied
Structure is complicated, component is more, manufacture difficulty is big, increase production cost, and some can also cause curtain because element structure is not reasonable
Body folding and unfolding is difficult, thus cannot extensive use.
The content of the invention
It is an object of the invention to provide a kind of rolling screen without pull rope simple in construction, easy to make.
It is a further object of the present invention to provide a kind of manufacture craft of above-mentioned rolling screen without pull rope.
For the curtain realized object above, rolling screen without pull rope of the invention, including curtain He be fixed on curtain upper and lower ends face
Bar, it is characterised in that：Direction of the curtain along length is provided with some parallel VELCROs, VELCRO one side from top to bottom
It is that circle hair, the another side of small, flexible are the setas of harder buckle, the one side of VELCRO band circle hair is placed in front or the back of the body of curtain
Face, the one side with seta are placed in the back or front of curtain same position, and the circle hair or seta of VELCRO protrude from the table of curtain
Face, the bar number and the width of VELCRO itself that VELCRO is set are set according to the size and weight of curtain.
Above-mentioned VELCRO is located at the inner side of curtain left and right edges, and is symmetrical arranged along the width of curtain.
Above-mentioned VELCRO can also be located at the left and right edges of curtain.
In order to more preferably increase the cohesive force that roller shutter is upwards collected through, above-mentioned VELCRO includes the evil spirit at curtain left and right edges
Art is pasted and the VELCRO among curtain.
Above-mentioned curtain is that the bamboo curtain splint formed, the evil spirit on the inside of bamboo curtain splint left and right edges are woven using bamboo silk or bamboo chip and warp thread
Art patch is to be woven during bamboo curtain splint weaves with warp thread into curtain, and VELCRO is in staggeredly stacked with bamboo silk or bamboo chip
Structure.
The above-mentioned VELCRO at bamboo curtain splint left and right edges is the surface that bamboo silk or bamboo chip are fixed on by sewing technology.
Above-mentioned curtain is using the door curtain made of cloth formed through resin treatment, on the inside of door curtain made of cloth left and right edges or left and right edges
VELCRO is the surface that cord is fixed on using sewing technology.
The above-mentioned VELCRO fixed using sewing technology, is by two magics positioned at curtain front and back same position
Patch composition, wherein the one side of VELCRO band circle hair is placed in the front or the back side of curtain, another VELCRO with seta one
Face is placed in the back or front of curtain.
The present invention also provides a kind of manufacture craft of above-mentioned rolling screen without pull rope, and the technique is first during curtain weaves
The VELCRO of strip is woven into curtain position set in advance with warp thread, makes VELCRO with bamboo silk or bamboo chip in staggeredly
Stacked state, then upper and lower curtain rod is fixed on to the upper and lower end face of curtain；Or first using sewing in molded curtain
The VELCRO of strip is fixed on curtain position set in advance by mode, then upper and lower curtain rod is fixed on to the upper and lower end face of curtain.
It is above-mentioned by the way of sewing to be the correspondence position in the positive precalculated position of curtain and the back side while sew on two
VELCRO, and make the one of wherein VELCRO band circle hair to face outwardly, another VELCRO one facing outwardly with seta.
The rolling screen without pull rope of the present invention, some parallel VELCROs are set using in the length direction of curtain under upper
Method, and VELCRO band circle hair and with seta while be placed in the positive back side of curtain, this can scroll up curtain
When rising, circle hair and seta on the VELCRO of curtain front and back same position can be bonded very well, this fitting production
The curtain that raw viscous force can make to roll is fixed on any position of window, and firmly one draws, and and can makes the circle hair and thorn of VELCRO
Hair natural separation, makes curtain easily put down, realizes real cordless operation.The rolling screen without pull rope of the present invention, is skillfully constructed, structure
Simply, low manufacture cost, use is particularly convenient, in American-European countries's feelings increasingly harsher to the standard with the outlet setting of rope curtain
Under condition, rolling screen without pull rope of the invention and its manufacture craft, the predicament that can will very well solve curtain export sector and face.
