Abstract

The objective of the invention is to provide a rolling curtain device with patch springs inlaid at the side of the rolling curtain. Its advantages lie in that it can be easily manufactured and inlaid; the spring can be restored after being rolled up by reel so that it's easier to pull down and the curtain surface is flatter after being pulled down. The invention also provides a device which can brake during the whole course of curtain's lifting without springs.

Description

A kind of roller blind device

What the present invention relates to is a kind of roller blind device.In conventional device, Chinese patent publication number: CN1464168A, open day: on December 31st, 2003, the device of " mosquito-proof or sun-shading blind device " by name.Because what adopt is the plane scroll spring technology of " pasting the curtain limit ", be to want that scrollwork by spring and flaring property reach to rotate curtain rolling shaft and can support the curtain face again and make it straight purpose theoretically.But, can not use through deep experimental results show that.Reason is that elasticity decline can appear along with the increase of stretching number of times in spring, and their elasticity and scrollwork shape can not be consistent when being straightened reinstatement again after two springs " paste the curtain limit ", and the both sides of curtain therefore lifting are unequal and stick.And spring will roll separately according to the height of each device, and the spring that scrollwork also is difficult to carry out Colaesce with the curtain limit.In view of all worn-out ends, this technology is promptly abandoned in person by its patent applicant.

The purpose of this invention is to provide a kind of mature technology: at the left and right edge Colaesce flat spring of curtain through practical proof.Because flat spring itself is straight, so the curtain face that supports also is straight.And draw high the power of falling and can drop on one's body the flat spring, can not cause hurt to the curtain face.Therefore this technology is applied to need soft curtain particularly line knit in the device of curtain and can produce fabulous effect, produce good benefit.

Technical scheme and embodiment:

This device mainly by curtain, curtain rolling shaft, lead curtain rail, curtain drawbar, reel, underframe 3 and formed.

On the left and right inwall of reel 1, set up the horizontal jack-post 12 that holds, on top 15 of hollow curtain rolling shafts.The inwall end that the rolling bearing 13 that holds jack-post is positioned on curtain rolling shaft is worn in the centre.Excavate the adaptation position of curtain rolling shaft, the spring 14 that is rolled into the scrollwork shape by flat spring be positioned on axle the inside, allow spring the inner ring end with hold jack-post and connect in fact, the outer ring end of spring connects real (please refer to the structural principle of coil chi) with the inwall of axle.After being rotated, axle can turn round automatically.Another kind of structure is to put into one to connect real fixture 23 at the middle part of axle with the axle inwall, at fixture and hold connect in fact between the jack-post 21 on stretching rubber bar 22.

Cut out suitable flat spring 6,8,16 usefulness bonding sew up or other feasible method Colaesces on the left and right edge of curtain 4,7,17.The upper edge of curtain is connected on the tangible curtain rolling shaft 10, the lower edge of curtain is connected on the tangible curtain drawbar 18.

The cross section of leading curtain rail 2 is made " recessed " font, leading the recess 9 that arrangement is set on the forward and backward inwall of curtain rail.In the end of curtain drawbar the plush copper made from the rhombus spring is set, one jiao 19 of the rhombus spring is fixed on the curtain drawbar end, and plush copper is by rope 20 controls, and plush copper can be stretched, and plush copper can be stuck in 11 li of recesses when the rope pine, stops the lifting of curtain.

Claims

1, a kind of roller blind device comprises curtain, curtain rolling shaft, curtain drawbar, leads the curtain rail, it is characterized in that: the left and right edge Colaesce of curtain flat spring (6,8,16).
