[Prior art]
In addition to screen doors that can be opened and closed by pulling back and forth by retracting an accordion-shaped net that is alternately folded in the opposite direction, it is generally a screen device that has a screen that can be opened and closed, that is, a screen frame that has one end held by a screen frame. In a screen device in which the other end of the screen is attached to a movable rod that is guided by the screen frame and used for opening and closing operations, and the screen is opened and closed by the operation of the movable rod, the movable rod is guided by the screen frame or the like. Therefore, the movable rod can be translated while maintaining its posture by a tension string constituting a translation mechanism stretched between the movable rod and the screen frame. .
[0003]
However, the parallel movement mechanism may be attached by twisting the tension string due to a misplacement of the turning element, particularly during assembly or maintenance at the site. In other words, it is not necessary to give consideration to prevent the string from being distorted in a part where the string is not likely to be twisted or entangled, such as a part where the string is inserted into the screen. Like the part where the string is wrapped around the turning element and folded back, in advance, the part where the turning string is properly assembled by inserting the turning element through the tension string having a sufficient length, as shown in FIG. At the stage of setting the screen 22 to which the tension string 23, the turning element 24, etc. are attached to the screen frame 20 together with the movable rod 21, the tension string 22 is twisted even if it is not entangled. There is a possibility that a turning element may be attached, and unless the twist is carefully checked and set on the screen frame 20, the movable rod 21 cannot be normally moved in parallel. However, the necessity of such work itself is a problem in terms of workability.
[0004]
In addition, even if a means for eliminating such twisting of the tension string is provided separately, it is not realistic to eliminate the twisting of the tension string with simple means if the various costs required for this increase. Is required.

DETAILED DESCRIPTION OF THE INVENTION
1 to 3 show an embodiment in which the screen device according to the present invention is implemented as a horizontal insect screen door.
This screen door is an accordion-type screen that expands and contracts, that is, an insect-proof net that can be opened and closed by lateral pulling. In general, the screen frame (screen door frame) 2 and the screen frame 2 can be opened and closed laterally. A net 4 that is freely attached and a movable rod 5 for opening and closing that is attached to one end of the net 4 are provided.
[0012]
The screen frame 2 has left and right vertical frame members 6 and 8 and an upper frame member 10 at the top, and a flexible net guide for suppressing the shaking of the net 4 is provided at the lower part of the screen frame 2. 12 is provided so as to appear and disappear as the movable rod 5 moves. One end of the net guide 12 is fixed to the lower end of the movable rod 5, and in accordance with the expansion and contraction of the net 4 accompanying the movement of the movable rod 5, the net guide 12 curves into and out of the left vertical frame member 6 in the drawing. By guiding the lower end of the net 4 in the stretched state and holding the lower end, shaking of the lower end of the net 4 due to wind or the like is suppressed.
However, instead of the net guide 12, a lower frame member for guiding the movable rod 5 and the lower portion of the net 4 may be provided between the left and right vertical frame members 6 and 8 at the lower portion of the screen frame 2.
[0013]
As can be seen from FIGS. 1 to 3, the net guide 12 is configured by partially cutting a part of an extruded material having a substantially U-shaped cross section made of an elastic flexible synthetic resin. That is, a pair of left and right swings formed by cutting a bottom portion 12b that follows the lower end of the net 4 and a plurality of recessed portions 12c that rise up along the front and rear outer surfaces of the net 4 and allow the bottom portion 12b to bend. It is configured as a long material having a substantially U-shaped cross section including the stoppers 12a and 12a.
Further, as shown in FIG. 2, the guide protrusions 12e and 12e provided on both sides of the bottom portion 12b are provided with guide portions B having a height of a sill that does not obstruct walking on the floor surface of the building opening. By inserting the guide portion B between the guide protrusions 12e and 12e, the net guide 12 can be properly slid along the guide portion B, that is, the net 4 can be properly opened and closed. Is to do.
[0014]
The net 4 is alternately foldable in the opposite direction and applied with a large number of pleats in a zigzag shape so that the net 4 can be expanded and contracted in an accordion manner. Opening and closing operations of the vertical frame member 6 of the screen frame 2 and the net 4 at both ends thereof A movable rod 5 is attached, and is opened and closed by operating the movable rod 5.
In order to stably translate the movable rod 5 attached to one end of the net 4, the movable rod 5 is provided with a translation mechanism. This parallel movement mechanism is configured by stretching two tension strings 14 a and 14 b between the screen frame 2 and the movable rod 5.
[0015]
One end of the first tension string 14 a is attached to the upper part of the movable rod 5, and this tension string 14 a passes through the horizontal frame member 10 at the upper part of the screen frame 2 and is one vertical frame member to which the net 4 is not attached. 8 is wrapped around a turning element 16a provided on the upper part of the frame 8, and then the inside of the horizontal frame member 10 is folded back and wound around a turning element 16b provided on the upper part of the other vertical frame member 6. It is guided downward, and is further wound around a turner 16 c at the lower part of the vertical frame member 6 and led out to the net 4 side. The net 4 is penetrated and the tip thereof is connected to the lower part of the movable rod 5.
On the other hand, the second tension string 14b is attached at one end to the upper part of the movable rod 5 and penetrates the net 4 and is then wound around a turning element 16d provided on the vertical frame member 6. After being guided downward and wrapped around a turning element 16e provided at the bottom, the tip is connected to the inner end of the net guide 12.
[0016]
In the part where the above-described tension strings 14a and 14b are stretched in the horizontal direction in the stretched portion of the net 4, the slack of the net 4 is prevented by inserting the tension strings 14a and 14b into the net 4. The tension state of the net 4 can be stabilized.
[0017]
In the embodiment shown here, a parallel movement mechanism using the net guide 12 is employed. However, this parallel movement mechanism is not limited to such a configuration example, and the movable rod 5 and the screen frame 2 are arranged. Various tension modes can be adopted that include a tension string stretched between them, and at least a portion of the vertical frame member 8 of the screen frame 2 that wraps around the turning element and is turned back. Various configurations that enable the parallel movement of the heel 5 while maintaining its posture can be employed.
[0018]
The tension string 14a extending in the opening / closing direction of the net 4 along the upper frame member 10 of the screen frame 2 is wrapped around the turning element 16a and folded back in the vertical frame member 8, and the turning element 16a used for this portion is the same as described above. As described above, since the tension string 14a is often twisted (see FIG. 6), it is rotatably attached to the vertical frame member 8 so that the twist can be eliminated. That is, as shown clearly in FIGS. 1 and 4, the diverter 16 a includes a winding portion 17 that wraps the tension string 14 a in a direction in which it is folded, and a fitting shaft portion 18 provided integrally therewith, More specifically, the wrapping portion 17 of the tension string is inside the annular member 17a having the tension string insertion hole 17b, and a winding portion 17c around which the tension string 14a to be folded is wound is formed on an arc surface. Further, the fitting shaft portion 18 includes a shaft 18a and a retaining member 18b that project integrally with the winding portion 17, and these are integrally formed of synthetic resin.
In addition, as each of the other diverters 16b to 16e, a synthetic resin sliding member having a small resistance to the tension strings 14a and 14b, or a member having a known structure such as a pulley can be used.
[0019]
The turning element 16a is attached to the screen frame 2 by inserting the fitting shaft portion 18 of the turning element 16a into the notch 19 at the upper end portion of the vertical frame member 8 of the screen frame 2 so that the upper end of the vertical frame member 8 is fixed. By connecting the end of the upper frame member 10 to the upper frame member 10, the turning element 16 a is held at the upper end of the vertical frame member 8. It is desirable to narrow the opening 19 to such an extent that the fitting shaft portion 18 can be press fitted.
In this way, when the turning shaft 16a is attached to the vertical frame member 8 by inserting the fitting shaft portion 18 of the turning device 16a into the notch 19 at the end of the vertical frame member 8 so as to be rotatable, it is easy. The deflector 16a can be attached, and even if the tension string 14a is twisted during assembly as shown in FIG. 5A, the twist is twisted as shown in FIG. Can be resolved.
[0020]
Further, the dropping of the turning element 16a from the cut 19 of the vertical frame member 8 can be suppressed by attaching the upper frame member 10 to the end portion where the cut 19 of the vertical frame member 8 is provided. Although the turner 16a can be freely rotatable in the fitting shaft portion 18, the rotation can also be suppressed by partial contact between the upper frame member 10 and the turner 16a.
[0021]
In the horizontal sliding screen door having the above configuration, the net guide 12 enters and exits from the lower end of the vertical frame member 6 to which one end of the net 4 is attached in accordance with the expansion and contraction of the net 4, and the net 4 is stretched. In some cases, the net guide 12 is led out along the lower end of the net 4 and is guided while the lower end of the net 4 is held to suppress the shaking of the net 4. Further, when the net 4 is folded and stored, there is no horizontal frame member below the building opening as in the case of a conventional screen door, and obstacles to walking for persons entering and leaving the building opening can be eliminated.
[0022]
When assembling and maintaining the screen device, the net 4 is set on the screen frame 2 with the movable rod 5 and the tension string 14a constituting the parallel movement mechanism attached thereto. In the portion of the tension string 14a wound around 16a and folded back, the net 4 and the tension string 14a are turned in advance in a portion that has been previously gathered in a state having a sufficient length and inserted through the turning element 16a. The tension string 14a may be twisted at the stage of setting the child 16a or the like on the screen frame 2, but the vertical axis member of the screen frame 2 can be fitted to the fitting shaft portion 18 of the diverter 16a without carefully returning the twist. 8 is inserted into the notch 19 at the upper end of 8 and is held rotatably, and then it can be rotated to easily eliminate the twisting of the tension string, thereby moving the movable rod 5 normally in parallel. The Rukoto becomes possible.
[0023]
The parallel movement mechanism functions to move the movable rod 5 in parallel even when a force for opening / closing operation is applied to a part of the movable rod 5. Is operated in the direction in which the net 4 is folded, the lower portion of the movable rod 5 is driven in the same direction via the first tension string 14a connected to the upper end of the movable rod 5, and the lower portion of the movable rod 5 is moved in the same direction. Is operated, the upper portion of the movable rod 5 is driven in the same direction via the second tension string 14b connected to the end of the net guide 12 connected to the lower portion of the movable rod 5. As a result, the movable rod 5 is driven. Can be translated.
[0024]
