Abstract

An upward blind can be supported at the both ends of the roller together with the roller bracket fixed by the window frame. The blind body wholly or partially winds around the roller, which comprises an upper one parallel with a lower one. The end of the two rollers has shaft teeth forming a gear. A pull rope jogged with the shaft teeth is hanged between the corresponding gear of the upper roller and the lower roller. In addition, one end of the blind body is fixed at the lower roller, while the other end is fixed on a transverse bar, the both ends of which are fixed on the pull ring at both sides. A button type bolt is mounted on the lower roller bracket and able to insert the fixed hole on the end face of the lower roller. When the blind is closed incompletely, the upward prevents the sunlight from shining directly on the window inside the room, to avoid irritation of the strong sunlight on people; and is equally useful for the situation where people do not want the indoor conditions noticed by the exterior people, thereby using the blind to shade the lower part of the window. In addition, the blind needs not to be obtained by climbing high to be washed, which changes the use method of the blind, with more convenient use and reasonable design.

Summary of the invention:

The purpose of this utility model provides a kind of up curtain, is not stopping that sunshine directly impinges upon window place in the room, avoids the stimulation of high light to the people under the Close All curtain situation.

The purpose of this utility model realizes as follows: this curtain relates to spool, scroll rack and curtain body, can be supported on the spool two ends with the scroll rack that window frame is fixed, curtain body is wrapped on the spool in whole or in part, spool is parallel two up and down, the end of two spools has a tooth to constitute gear, prolong knot has the stay cord that is meshed with the axle tooth between the gear of upper winding shaft and lower winding shaft corresponding sides, each stay cord forms the ring body of sealing, curtain body one end is fixed on the lower winding shaft, the other end of curtain body is fixed on the cross bar, the cross bar two ends are fixed on the stay cord of both sides, and the push button latch that can insert in the lower winding shaft end face fixing hole is housed on the last volume pedestal.In the time of need all opening curtain, curtain body all is wrapped on the lower winding shaft; In the time of need closing curtain, the pulling stay cord, the stay cord motion drives the spool rotation simultaneously, one end of curtain body moves up under cross bar drives, shielding window gradually is up to can all covering whole window, after shade position mixes up, by the latch on the last volume pedestal spool is fixed, thereby curtain is located.Because desks etc. are general near window, when sun lights is on table top, the up certain distance of curtain is covered sunlight, make the sunshine that does not have direct projection on the table top, window top sees through next sun lights other position in the room, making has enough lights in the room, can not stimulate the eyes that are in the desk location personnel again.

Stay cord is made of rope body and the orbicule that can be meshed with the axle tooth that is rolled on the rope body, and orbicule can be made of plastics, and the shape of orbicule and spacing just in time adapt to the tooth-formation of gear and the tooth pitch of spool.This stay cord also can be the rubber saw tooth belt.

Cross bar is fixed on the inner side edge of stay cord annular, and the handled easily personnel grasp the stay cord in the outside like this, open or close curtain.

This up curtain, can not stop that sunshine directly impinges upon window place in the room under the Close All curtain situation, avoid the stimulation of high light to the people, equally also be applicable to when not wanting to allow the people of outside see in the room situation, only with curtain shielding window Lower Half, also needn't ascend a height when needing to clean curtain and win, it has changed the using method of curtain, use more conveniently, it is more reasonable to design.
