A curtain rail

Abstract

A guide rail for a curtain, comprising a rail (1), runner devices (2), and a transmission mechanism (3); the rail (1) comprises a runner groove (11) and a gear rod groove (12), the runner groove (11) and the gear rod groove (12) being in communication with each other by means of a cutout (13); a gear rod (14) is provided in the gear rod groove (12); the transmission mechanism (3) drives the gear rod (14) to rotate in the gear rod groove (12), the transmission mechanism (3) drives the runner devices (2) to move in the runner groove (11), and the gear rod (14) is fitted with the runner devices (2). Said guide rail for a curtain can be used for an arc-shaped window, has a small running resistance, a low noise output, and a long service life; a slat will not be rotated by wind, and the sticking of a small number of slats will not affect the rotation of other slats; the rail (1) can be transported in segments, the gear rod (14) can be made of a rigid material to be transported in segments or made of a flexible material to be transported by being packaged, reducing the transportation cost.

Description

technical field [0001] The invention relates to a curtain device, in particular to a curtain guide rail. Background technique [0002] At present, most of the curtains with turnable blades on the market use linear tracks, but with the improvement of people's living standards, the use of curved windows at the corners of houses is gradually increasing, and traditional linear tracks cannot match the contours of curved windows. [0003] The existing curtain guide rails are mainly divided into two types. One type passes through the ball-rolling device through a linear rigid gear rod, and fixes it on the accessories at both ends of the track by using a device such as a middle bracket slider. It is a two-step control operation. If this model is made into an arc shape, the gear rod and the arc of the track cannot be kept exactly the same. When the ball bearing device and the center slider slide to the arc section, the resistance is too large, and it cannot run and use smoothly. The...

Problems solved by technology

[0002] At present, most of the curtains with turnable blades on the market use straight-line tracks, but with the improvement of people's living standards, the use of curved windows at the corners of houses is gradually increasing, and traditional straight-line tracks cannot match the contours of curved windows.

[0003] The existing curtain guide rails are mainly divided into two types. One type passes through the ball-rolling device through a linear rigid gear rod, and fixes it on the accessories at both ends of the track by using a device such as a middle bracket slider. It is a two-step control operation. If this model is made into an arc shape, the gear rod and the arc of the track cannot be kept exactly the same. When the ball bearing device and the center slider slide to the arc section, the resistance is too large, and it cannot run and use smoothly. The size of the window is too large to be used in multi-stage splicing; the other type, the operation and rotation of the ball rolling device is driven by a single transmission force, and its structural principle is a belt-type transmission, which first drives the differential gear of the ball rolling device in the track to rotate, and then drives it to run The first bead device at the end, the bead device pulls all subsequent bead devices to run

This kind of guide rail ball device has a large number, large power demand, high requirements on the transmission system, high cost or short service life, many faults, and is not stable and durable for windows over 3 meters

[0004] In addition, traditional curtain guide rails still exist: the bead device rubs against the inner walls of both sides of the track at the arc track, resulting in increased resistance and unsmooth operation; deviation between the gear rod and the radian of the track leads to unsmooth operation; it is inconvenient to transport the guide rail to tall buildings , only the track is disassembled in sections, and the operation of the bead device at the joint is not smooth; a single blade is stuck and other blades cannot rotate; the rotation angle of the blade is affected by the wind and changes, etc.
