Description

[Detailed Description of the Invention] This invention relates to a screen door device that allows building openings such as building entrances and windows to be shielded and opened by a screen door.

In general, since mesh materials have low molding rigidity,
In order to shield the opening of a building with a screen board, a solid screen door such as a door or sliding door is used, in which the screen board is surrounded by a solid frame on all four sides.As a result, when the screen door is opened, it is difficult to store the screen door. However, there was no choice but to store it in its original form in a place where it would not get in the way as much as possible, and as a result, there was a problem that the space efficiency during storage was not good.

The present invention was devised to solve the above-mentioned difficulties, and the purpose of the present invention is to use a flexible screen door that can be rolled up and stored, and to provide the screen with sufficient tensile strength when shielding. An object of the present invention is to provide a screen door device that can be held.

Hereinafter, the present invention will be explained based on an illustrated embodiment.

As shown in Figs. 1 to 5, the screen door device of the embodiment is installed in a window opening 1a of a building 1. A pair of guide rails 2, 3 having a U-shaped cross section are erected on the left and right side edges of the opening 1a. On the opposing surfaces of each rail 2, 3, there are guide grooves 2a,
A bottomless, long box-shaped storage case 4 is formed above the width region between the guide rails 2, 3, and the case 4 is fixed to a recessed portion or the like of the outer wall of the building 1.

Further, at the upper end of the storage case 4, a fixed shaft 5 is horizontally suspended, and a winding tube 6 is fitted onto the fixed shaft 5. The energy-storing coil spring 7, which is supported by a bearing and wound in the space between the fixed shaft 4 and the winding tube 5, is
One end thereof is fixed to the fixed shaft 4, and the other end is fixed to the winding cylinder 6.

Next, a pair of transmission pulleys 8 are fixed to the left and right ends of the winding cylinder 6, and a pair of transmission pulleys 8 are fixed to the side plates at the lower ends of each guide rail 2, 3 directly below the transmission pulleys 8. A pair of driven pulleys 9 are supported by bearings, and left and right guide wires 10 are routed between both pulleys 8 and 9.

The guide wire 10 is wound around the circumferential surface of the transmission pulley 8 multiple times (one and a half times in the illustration) in order to prevent slippage during transmission, and both ends of the wire are wrapped in a loop shape via a tension spring 11. It is tied to

By the way, the screen door 12 is made of a flexible mesh plate whose four circumferences are secured with thin wire to prevent fraying.The upper end of the screen door 12 is fixed to one location on the periphery of the winding tube 6, and the lower end is connected to the front and rear L-shaped water drains. The left and right clips 16 are sandwiched between the plates 13 and fastened with setscrews 14 at multiple locations, and are further fastened to the left and right ends of the drain plate 13 with two screws 15 each. Between the plate surface of the side projecting portion and the retaining plate portion of the head of the fastening screw 17 screwed into the side projecting portion,
A wire 10 is sandwiched between them.

In addition, stoppers 18 made of L-shaped pieces are fixed at two locations on the left and right sides of the vertical plate of the draining plate 13, and the bottom opening of the storage case 4 located directly above the stoppers 18 is provided with a stopper 18 made of a long plate. The guide 19 is installed across the front and back, and the slit between the rising edges 19a formed in the middle of the guide 19 has a
A screen door 12 is guided through it.

Next, the operation of the screen door device of the embodiment configured as described above will be explained.

The guide wire 10 is strongly tensioned by the tensioning action of the tension spring 11, and the guide wire 10 is
The screen door is slidably moved in conjunction with the movement of the outer periphery of the screen door, and its upper and lower ends are respectively held at a fixed point on the circumferential surface of the winding tube 6 and a fixed point for the guide wire 10. 12 is driven by the winding cylinder 6 and moves up and down in an expanded state like a solid state.

Therefore, in order to open the screen door 2 which is in the closed state shown in the figure, all that is required is to release the locking of the drain plate 13 by a magnet or the like and push it up. When the drain plate 13 is released, the coil spring 7 The winding tube 6 rotates in the winding direction due to the stored elasticity, thereby opening the screen door 12.
moves up and down.

Further, at the end of the lifting movement, the stopper 18 hits the bottom of the guide 19, thereby keeping the screen door 12 in the open position.

Note that in this open state, the tension spring 11
has descended to a position close to the driven pulley 9.

Next, in order to close the screen door 12, it is sufficient to manually pull down the draining plate 13 while resisting the elasticity of the coil spring 7 and accumulating the spring 7.
When the draining plate 13 is locked at the point where the screen is one cup lower, the screen door 12 is kept in the closed position.

During such operation, even though the screen door 12 itself has low molding rigidity, the screen door 12 is regulated and held by the guide grooves 2a, 3a of the guide rails 2, 3 and the guide wire 10, so that the screen door 12 does not become loose or wrinkled. In addition, according to the above-described structure, the screen door 12 is stored by winding up, so the space of the device is extremely compact.

As described above, according to the screen door device according to the present invention, the flexible screen door is housed in the winding tube horizontally suspended directly above the opening, and when the screen door is closed, the drain plate at the lower end of the screen door is Since the screen door is configured to be held by the guide wire in a hanging shape, the screen door can be stored compactly, and the screen door can maintain sufficient tensile strength when closed, which makes the screen door device easy to install. This has the effect of increasing marketability.

Further, according to the present invention, the left and right ends of the lower end of the screen door 12 can be attached and fixed by sliding them to any adjustment intermediate position of the endless guide wire 10 for opening and closing the screen door by tightening and loosening the tightening screws 17. Therefore, even if the screen door 12 becomes misaligned due to long-term use, the screen door 12 can be adjusted to a horizontal position by easily adjusting the mounting positions for the guide wires on the left and right sides of the screen door. .
