DOUBLE-ROLLER CURTAIN MOUNT STRUCTURE

Abstract

A double-roller curtain mount structure includes a fixing bracket, a support rod and two fixing members. The support rod is fitted through and connected with the fixing bracket. The two fixing members are locked on the support rod to fix the support rod on the fixing bracket. The support rod has an internal space. Two roller curtain assemblies can be inserted into the internal space of the support rod from two sides of the fixing bracket to get closer to the fixing bracket so as to shorten the light gaps between the two roller curtains and the fixing bracket and enhance the sunlight shading effect of the roller curtains.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a double-roller curtain mount structure, and more particularly to a double-roller curtain mount structure, which is able to shorten the light gaps between the fixing bracket and the roller curtains.

2. Description of the Related Art

Due to the limitation of operation of the roller curtain sheet, the lateral side of a conventional roller curtain is generally spaced from the wall face by a gap. As a result, the sunlight will partially pass through the gap into a room to lower the sunlight shading effect. With respect to installation of a double-seat roller curtain, a gap exists between the two roller curtains. This more seriously deteriorates the sunlight shading effect. Especially, the current double-roller curtain mount structure has a middle fixing bracket in which the roller curtain assemblies are inserted. The protruding length of the fixing rod of the roller curtain assembly is shorter so that it is uneasy to fix the roller curtain assembly on the fixing bracket. As a result, the roller curtain is likely to detach and drop from the fixing bracket.

SUMMARY OF THE INVENTION

It is therefore a primary object of the present invention to provide a double-roller curtain mount structure, which is able to shorten the light gaps between the fixing bracket and the roller curtains. The double-roller curtain mount structure includes a fixing bracket, a support rod and two fixing members. The support rod is fitted through and connected with the fixing bracket. The two fixing members are locked on the support rod to fix the support rod on the fixing bracket. The support rod has an internal space. The protruding fixing rods of the roller curtain assemblies are inserted into the internal space of the support rod to make the roller curtain sheets closer to the fixing bracket so as to shorten the light gaps between the two roller curtains and the fixing bracket and enhance the sunlight shading effect of the roller curtains.

To achieve the above and other objects, the double-roller curtain mount structure of the present invention includes: a fixing bracket having a horizontal face and a vertical face, the vertical face being formed with a through hole; a support rod, which is a hollow rod body, the support rod being fitted through the through hole of the fixing bracket, the rod body having a central passage, an outer thread being formed on outer circumference of the rod body; and two fixing members, each of the fixing members having a main body, the main body having a central perforation formed with inner thread for screwing on the outer thread of the support rod, whereby the protruding fixing rods of the roller curtain assemblies can be inserted into the central passage of the support rod to make the roller curtain assemblies closer to the fixing bracket so as to shorten gaps between the roller curtains and the fixing bracket.

The present invention can be best understood through the following description and accompanying drawings, wherein:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to FIG. 1. The double-roller curtain mount structure of the present invention includes a fixing bracket 1, a support rod 2 and two fixing members 3, 4, which are assembled with each other. The fixing bracket 1 has a horizontal face 10 and a vertical face 11. The horizontal face 10 is formed with slots 100. Securing members can pass through the slots 100 to secure the fixing bracket 1 on a wall face. The vertical face 11 is formed with a through hole 110 for the support rod 2 to pass through. The support rod 2 is a rod body with a predetermined length. The rod body has a central passage 20. An outer thread 21 is formed on outer circumference of the support rod 2. The two fixing members 3, 4 are screwed on the outer thread 21. The two fixing members 3, 4 are respectively screwed and tightened on left and right sides of the support rod 2. The right side fixing member 3 has a main body 30. The main body 30 has a central perforation 31 formed with inner thread 32 for screwing on the outer thread 21 of the support rod 2. The left side fixing member 4 also has a main body 40. The main body 40 has a central perforation 41 formed with inner thread 42 for screwing on the outer thread 21 of the support rod 2 protruding from one side of the fixing bracket 1. Accordingly, the two fixing members 3, 4 are locked on the support rod 2 to fix the support rod 2 on the fixing bracket 1 with the passage 20 of the support rod 2 exposed to outer side (as shown in FIG. 2).

Referring to FIG. 3, when assembled, securing screws 101 are passed through the slots 100 of the horizontal face 10 of the fixing bracket 1 to lock the fixing bracket 1 under an upper wall face of a window 7 with the vertical face 11 of the fixing bracket 1 suspending in front of the window 7. Then the support rod 2 is fitted through the through hole 110 of the vertical face 11 of the fixing bracket 1 with two ends of the threaded rod body protruding from the left and right sides of the fixing bracket 1. The inner threads of the fixing members are screwed on the outer thread 21 of the rod body so as to fix the support rod 2 on the fixing bracket. The fixing rods 50 of the roller curtain assemblies 5 are assembled in the passage 20 of the support rod 2 (as shown in FIG. 4).

Please refer to FIGS. 5 and 6, which show the installation of the roller curtain assemblies 5 on the fixing bracket 1. The roller curtain sheet is fitted on the reel 6 of the rear end of the roller curtain assembly 5. A fixing rod 50 and a stopper plate 51 are disposed at the front end of the roller curtain assembly 5. An elastic member 52 is positioned behind the fixing rod 50 and the stopper plate 51 to elastically support the same, whereby the fixing rod 50 and the stopper plate 51 are extensible and retractable (as shown in FIG. 6). In installation, the roller curtain assembly 5 is first tilted by an angle to aim the fixing rod 50 at the passage 20 of the support rod 2. Then the fixing rod 50 is inserted into the passage 20 until the stopper plate 51 abuts against the support rod 2 and the elastic member 52 is compressed (as shown in FIG. 6). When the roller curtain assembly 5 is positioned in a horizontal state, due to the elastic restoring force of the elastic member 52, the other end of the roller curtain assembly 5 is pushed to engage with a lateral fixing bracket (as shown in FIG. 7) to complete the installation of the roller curtain device.

When the installation of the roller curtain device is completed, the remaining elastic force of the elastic member 52 will further forward push the roller curtain sheet 6 to make the fixing rods 50 of the roller curtain assemblies 5 left and right abut against each other (as shown in FIGS. 8 and 9). Under the elastic force of the elastic members 52, the stopper plates 51 will be embedded in the roller curtain assemblies 5 (as shown in FIG. 10) to compress the elastic members 52. Accordingly, the two roller curtain sheets 6 are closer to the fixing bracket 1 to shorten the light gaps between the roller curtain sheets 6 and the fixing bracket 1 (as shown in FIG. 11).

The above embodiments are only used to illustrate the present invention, not intended to limit the scope thereof. Many modifications of the above embodiments can be made without departing from the spirit of the present invention.
