Description

Roll screen

The present invention relates to a roll-type screen window, which mainly refers to a screen window that can stably position the unfolded position of the screen.

The conventional scroll screen window mainly has a window frame, a roller device, a gauze net, and a stretching device. The roller device is pivoted on the window frame, has a roller, and is arranged inside the roller so that it can be The coil spring twists when the drum rotates; the gauze is wound around the outside of the drum, and one end is connected to the drum; and the stretching device can correspond to the displacement of the window frame, and one end is connected to the other end of the screen. A hooking device is also provided, and the stretching device can stretch the gauze to unfold and hook the hooking device with the window frame to locate the unfolding position of the screen. At the same time, the gauze drives the drum to rotate and twist the coil spring, and the When the hook device is separated from the window frame, the elastic restoring force of the coil spring allows the drum to automatically rotate and retract the gauze.

Although the aforementioned structure can automatically roll up the gauze, the gauze can only be unfolded and positioned at the unfolded position where the hooking device can be hooked, and cannot be positioned at other positions, resulting in unsatisfactory applicability.

In order to improve the above-mentioned deficiencies, the screen window No. TWM596274 has a window frame, a reel device, a tensioning device, and a stop device. The reel device winds up a gauze net through elasticity, and the stop device is equipped with connectors, ropes, The winding unit and the adjusting piece are provided with the connecting piece on the window frame, and the rope is connected to the connecting piece; and the winding unit has a plurality of winding pieces arranged at the end of the tensioning device and provided with rope surroundings, and the The adjusting piece and the bolt piece are engaged with the winding piece and are located on the tensioning device, so that when the tensioning device is pushed, the gauze can be directly stretched and the reel is installed. The rotation generates a rebound force, and the rope can be turned multiple times to produce traction and blockage, so that the rope and the tensioning device can generate a resilience greater than the resilience of the reel device that stretches the gauze, so that the gauze deployment position can be positioned.

However, in the aforementioned structure, the relative resilience of the gauze of the reel device increases as it is stretched longer, and its resilience is not fixed, making it difficult to retract stably when the resilience is too small, and difficult to stabilize the positioning when the resilience is too large.

It is also observed that TWM250035 is similar to the above-mentioned screen window, with a frame, a roll-type screen assembly, and a positioning device. The roll-type screen assembly has a mandrel, a screen, a roll-back spring, and a movable frame, and it should be positioned The device mainly has two pull wires and two friction blocks. The friction blocks can press the pull wires and generate friction. This friction can offset the recovery force provided by the rewind spring composed of the drum or gauze, making the movable frame and The gauze can be deployed and positioned.

However, the design of the aforementioned friction block also has the disadvantage of being unable to stably position the unfolded position of the gauze due to uneven elasticity due to different unfolded lengths of the gauze.

The object of the present invention is to provide a screen mesh stable positioning structure that can provide a roll screen window.

The invention includes a window frame, a roller, a gauze, a sliding frame and a linkage device. The window frame is a rectangular body; the roller is arranged on at least one side of the window frame; and one side of the gauze The push frame is coupled with the reel and can be rolled up or unfolded correspondingly to the reel; the push frame is provided on the window frame and can be coupled with the other side of the gauze in response to the displacement of the window frame; and the linkage device It is provided on the window frame and has at least one guide wheel set, a rope body and at least one adjustment device. The guide wheel set has at least one first guide wheel connected with the end of the drum; and the rope body surrounds the The guide pulley set can drive the drum to rotate by the first guide pulley; and the adjustment device is engaged with the end of the rope body and can adjust the tightness of the connection between the rope body and the guide pulley set.

In one embodiment of the present invention, the linkage device includes two guide wheel sets, each of the guide wheel sets has a first guide wheel, a second guide wheel, and a third guide wheel, and the second guide wheel is located close to the At the first guide wheel position, the third guide wheel is disposed on one side of the window frame relative to the drum, and the rope body crosses and surrounds the first guide wheel and the second guide wheel in a figure-8 shape.

In one embodiment of the present invention, the first guide wheel, the second guide wheel, and the third guide wheel are circumferentially provided with ridges in contact with the rope body.

In one embodiment of the present invention, two opposite sides of the window frame are respectively provided with a drum, a gauze, a sliding frame, and a linkage device. The two sides of the window frame are respectively engaged with a drum, and the two linkage devices are respectively connected with the drum. A sliding frame is connected and each has at least one guide wheel set. Each guide wheel set has at least a third guide wheel located in the center of the window frame and is coaxially arranged, and the rope body is connected to the corresponding one. The guide wheel set is connected, and the third guide wheel can link the two linkage devices.

According to the present invention, the adjustment device can be used to ensure that the rope body and the guide pulley assembly have appropriate joint tightness, and the first, second, and third guide pulleys have convex ridges that can have greater contact friction with the rope body. Therefore, when the user pushes the push frame When displaced, the gauze can be driven to expand or retract, and the first guide wheel directly drives the drum to rotate accordingly. Therefore, the present invention does not require a spring in the drum to smoothly wind up the gauze, and The present invention makes the rope body intersect in a figure-8 shape between the first and second guide wheels so that it will not slip, which can improve the stability of the connection and joint of the rope body driving the first guide wheel, and enable the push frame to apply force to move the yarn at will. The net expands or contracts accordingly, and when no force is applied, the position of the push frame and gauze can be firmly positioned to achieve better positioning stability.
