Description

[Detailed description of the invention] This invention relates to an automatic winding device for a horizontal winding screen door, in which a winding barrel is installed at an opening such as an entrance or back door of a general household, and can be rolled up from one side to the other. It is.

Conventionally, various types of insect screen devices have been used for this type of opening, including one in which a sash screen is folded with a hinge, an accordion type with a hanging rail, and a rolling type that automatically rolls up vertically and horizontally. However, satsushi screen doors and accordion-style doors are complicated to install and adjust to the height and width of the opening, are time-consuming to install, and are often inconvenient to remove and store during the off-season. Also, top and bottom,
Both of the left and right winding and rolling types have drawbacks such as requiring a lot of effort to adjust the structure of the guide rail and making it difficult to adjust the winding force after installation.

This invention has improved the problems of the conventional inconveniences and inconveniences, and its features are that an automatic winding device is built into the winding barrel cover, which greatly simplifies mounting and operation, and also makes winding easier. The barrel is suspended by an upper bearing part, and hardening is achieved to reduce shaft resistance and facilitate winding spring adjustment. The main structure is that a winding guide frame is installed below the winding drum cover, and an adjustable frame is installed at the lower end.

Next, one embodiment of this invention will be explained with reference to the drawings.A horizontally winding screen door A installed in an opening such as an entrance or a back door has a central mesh body 1 made of various constituent materials and a winding body that winds up the mesh body 1. 2, and a movable crosspiece 3 that pulls out the net body 1
It is composed of. On the outer periphery of the winding drum 2,
A winding cylinder cover 4 with one side open is attached, and a winding guide frame 5 provided with rollers and the like is installed below the winding cylinder cover 4 on the inner surface of the winding cylinder cover 4. Further, an adjustable frame 6 that can be vertically adjusted in height is installed at the lower end of the winding cover 4 so as to be able to move up and down. Further, a locking piece 12 is provided inside the upper part of the winding drum 2 at the lower end of the winding spring 7, and a spring adjustment shaft 8 is fixed to the upper end of the winding spring 7. A worm wheel 9 is fixed to a spring adjustment shaft 8 protruding from the top of the winding barrel 2, and a bearing 10, which is provided above the winding barrel cover 4 and inserted through the spring adjustment shaft 8, engages with the worm wheel 9. A worm 11 is attached. Next, the movable crosspiece 3 provided at the tip of the net body 1 has an adjustable frame 13 at its lower end that can be raised and lowered to adjust the height, and a guide rail 19 which is telescopically attached to the upper end. A sliding runner 18 is installed. 14
1 shows a magnet provided on the door stop surface of the movable crosspiece 3. Further, a mounting bar 16 to which the winding body cover 4 can be fitted is fixed to the vertical frames 15, 15 located on the left and right sides of the opening, and a receiving bar 17 on which the movable bar 3 rests is fixed to the other. is fixed. 20 is an insect-proof cover that covers the guide rail 19 and the upper part of the net body 1, and 21 is a guide protrusion that guides the locking piece 12 up and down.

This device has the above-mentioned configuration, and to explain how to use this device now, the net body that is rolled up horizontally.
When closing the movable crosspiece 3 with a handle, the net body 1 whose strength of the winding spring 7 is adjusted by the worm 11 resists the winding spring 7 and moves toward the winding guide frame 5. It is guided and pulled out in an orderly manner, and the magnet 14 attracts the suction plate provided on the receiving bar 17 of the vertical frame 15 to maintain the closed state. Next, if you want to open it,
The magnet of the movable crosspiece 3 is unlocked and the winding spring 7 is used to easily and automatically wind up the net body 1 onto the winding drum 2.

As described above, according to this invention, the winding guide frame provided below the winding drum cover allows the winding and unwinding of the net to be carried out smoothly, and does not put strain on the net itself. It has an excellent effect that will not break or loosen. In addition, the adjustable frame provided at the lower end of the winding barrel cover can be raised and lowered according to the height of the opening, making it easy to adjust the dimensions, which is convenient for mounting. Furthermore, since the winding drum is suspended only by the upper bearing, this invention has the advantage that there is less resistance against the shaft and the winding spring can be easily adjusted.
