Each rope has a first rope section, and two second rope sections extending from opposite ends of the first rope section and connected to corresponding connecting members. Each winding unit is formed in a tensioning device that slides on the window frame, and guides the rope to travel from the first end to the second end after the first turn of the window frame, and to the second turn Travel towards the first end, and then travel towards the second end after the third turn, and after the last turn, enter the window frame from the second end, so that the first rope section follows The height direction passes through the tensioning device, and the second rope segments pass through the window frame in the reverse direction along the length direction and are separated by a distance along the height direction. In this way, the frictional resistance between each rope and the tensioning device is increased in multiple turns, so that the tensioning device can be used to tension a gauze, and is blocked by the ropes and stops at the window frame Anywhere.

Description

Stop device for screen window

The present invention relates to a kind, in particular to a follow-up device for screen windows.

Generally, a screen with a gauze is mainly used to automatically wind up the gauze with a reel having elasticity, and to stretch the gauze with one hand.

However, the aforementioned elastic force will not only cause greater impact and noise when the gauze rebounds, but also the handle will be subjected to elastic force all the time without being fixed, and cannot be stopped at any position.

Therefore, the purpose of the present invention is to provide a follow-up device capable of stopping the screen at any position of the screen.

Therefore, the following stop device of the new screen window includes a window frame defining a window, a reel device installed on one side of the window frame and used to wind a gauze, and a width direction along the window frame A tensioning device inserted through the window and connected to the gauze, the tensioning device has a first end and a second end which slide on the window frame along a length direction of the window frame and reverse The stop device includes four connecting pieces, two ropes, and two winding units.

The connecting members are arranged in the window frame around the window.

Each rope has a first rope section, and two second rope sections extending from opposite ends of the first rope section and connected to corresponding connecting members.

Each winding unit is formed in the tensioning device and guides the rope to travel from the window frame to the second end through the first end after the first turn and to the first end after the second turn The end portion travels, then travels toward the second end portion after the third turn, and enters the window frame from the second end portion after the last turn.

Thereby, the first rope segment is passed through the tensioning device along the height direction, and the second rope segments are passed through the window frame in the reverse direction along the length direction and separated by a distance along the height direction.

The effect of the present invention is to increase the frictional resistance between each rope and the tensioning device in multiple turns, so that the tensioning device can be used to tension a gauze, and is stopped by the ropes and stops at Any position of the window frame.

Referring to FIGS. 1 and 2, an embodiment of the novel stop device is installed on a screen 1. The screen 1 includes a window frame 11 defining a window 10, a reel device 12, and a tension device 13.

The window frame 11 includes two rail frame members 111 extending along a length direction X and separated by a distance along the width direction Y, and connected to the rail frame members 111 along a width direction Y and separated by a distance along the length direction X的二边架件 112。

The reel device 12 is installed on one side frame member 112 of the window frame 11 and winds a gauze 14 by an elastic force.

The tensioning device 13 penetrates the window 10 along the width direction Y and is connected to the gauze 14 and has a first end 131 that slides along the length direction X on the rail frame members 111 and is reversed与一个第一端部132。 With a second end 132.

Referring to FIGS. 3 and 4, the following stop device includes four connecting pieces 2, two ropes 3, two winding units 4, two adjusting pieces 5, and two bolt pieces 6.

The connecting members 2 are disposed around the window 10 at the two ends of the rail frame members 111 adjacent to the side frame members 112, so that the connecting members 2 are separated into groups of two along the width direction Y, Moreover, the two connecting members 2 of each group are spaced apart along the longitudinal direction X and are arranged in a rectangular shape.

Each rope 3 has a first rope segment 31 and two second rope segments 32 extending from opposite ends of the first rope segment 31 and connected to the corresponding connecting member 2.

Each winding unit 4 includes four winding members 41-44 in the form of a circular cylinder. Two of the winding members 41 and 42 are formed at the first end 131 of the tension device 13, and the other winding member 43 is formed at the second end 132 of the tension device 13.

Each adjusting member 5 is movably mounted on the tensioning device 13 along the width direction Y, and is located between the first end 131 and the second end 132, and has one for the remaining winding member 44 The opening 51 and a connecting portion 52 opposite to the opening 51.

Each bolt 6 passes through the connecting portion 52 of the respective adjustment member 5 and is forced against the tension device 13 to fix the respective adjustment member 5 on the tension device 13.

Through the guidance of the winding members 41-44, each rope 3 will pass through one of the connecting members 2 through one of the rail frame members 111 of the window frame 11, and after the first turning of the winding member 41, The first end 131 of the tensioning device 13 travels toward the second end 132, and then, after the second turn of the winding member 44 is interlocked with the adjustment member 5, and the adjustment member 5 faces the The first end 131 travels, and then passes the winding member 42 after the third turn to the second end 132, and after the winding member 43 turns the last time, enters from the second end 132 The other rail frame member 111 of the window frame 11 is connected to the other connecting member 2. By this, the first rope segment 31 of each rope 3 passes the tension device 13 along the width direction Y, and the second rope segments 32 pass through the rail frame members 111 in the reverse direction along the length direction X and There is a gap along the width direction Y.

Referring to FIG. 3, FIG. 4 and FIG. 5, when in use, only the pushing device 13 can be pushed along the width direction Y to overcome the elastic force of the spool device 12 to stretch the gauze 14, and in the stretching device 13 During the sliding process, the ropes 3 that are turned multiple times generate traction and blockage, so that the friction resistance between the ropes 3 and the tensioning device 13 is greater than the elastic force, and can be stopped at any position. This gauze 14 closes some windows 10 or closes all windows 10.

And importantly, through the change of the position of the respective adjustment member 5, the tension of each rope 3 can be adjusted, and then the resistance of each rope 3 can be changed. By this, according to the practice, when the resistance is greater, the The tensioning device 13 can be parked at a fixed position more stably, or the smaller the resistance, the easier the tensioning device 13 is pushed.

Through the above description, the advantages of the foregoing embodiments can be summarized as follows:

The present invention can increase the frictional resistance between each rope 3 and the tensioning device 13 with the ropes 3 turning multiple times, so that the tensioning device 13 can be blocked by the ropes 3 and stop at the window frame 11 Any position, not only simple structure, but also easy to use and operate.

However, the above are only examples of the new model. When the scope of the new model cannot be limited by this, any simple equivalent changes and modifications made according to the patent application scope and patent specification content of the new model are still regarded as Within the scope of this new patent.
