[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing screen which can be opened and closed in a winding or accordion manner.

[0002]

2. Description of the Related Art One end of an accordion-type screen door, that is, an accordion-type expandable and contractible net by applying a large number of pleats, is fixed to a storage case constituting one side of a screen door frame. At the door, an operation frame for opening and closing operation is attached to the end, and this operation frame can be moved along the guide frame.Since the posture of the operation frame is not restricted by the net, the posture is always kept constant and translated. Need to be done. Also, wrap the net on a roll,
In the rewind type screen door that stretches the net by rewinding it, when the net is in a tensioned state, the posture of the operation frame at the tip is temporarily restricted by the net, but it is not absolute, and the operation frame is Has a degree of freedom in posture.

[0003] In such an opening / closing screen door, it is desirable to provide a parallel movement mechanism for accurately moving the operation frame in parallel for stable opening / closing operation of the operation frame. No. 45820 (Japanese Utility Model Laid-Open No. 6-1696) proposes a parallel movement mechanism. However,
The proposed screen door has no problem in that the operation frame can be moved in parallel stably, but if the thickness of the screen door is to be reduced as much as possible according to the requirements of the screen door installation location, the following will be required. I found that there was a problem.

[0004] That is, in the above-mentioned proposed screen door, FIG.
As shown in FIG. 5, an operation frame 108 for opening and closing operation is attached to the other end of the net 102 having one end fixed to a storage case 104 constituting one side of the screen door frame 101, and one end is attached to both ends of the operation frame 108. The tension cords 111 and 112 are wound around pulleys 113 and 114 installed at both ends of a frame receiver 107 located on the opposite side of the storage case 104, and the tension cords are turned back and provided at both ends of the storage case 104. Around the pulleys 115 and 116, and further, tension cords 111 and 11 from those pulleys 115 and 116.
2 is wound around pulleys 117 and 118 provided on the half of the storage case opposite to the position of each pulley.
The ends of the cords 111 and 112 are fixed to the operation frame 108 along with the net 102.

In such a screen door, pulleys 11 for tension cords 111 and 112 are provided at the upper end of the storage case 104.
5 and 118, these pulleys are rotated in opposite directions because the tension cords 111 and 112 run in opposite directions at that part when the operation frame 108 moves in an arbitrary direction. Therefore, it cannot be replaced by a single pulley to simplify the structure. This is the pulley 11 at the lower end of the storage case 104.
The same applies to 6,117. Further, even if the two pulleys at the upper and lower ends are provided at an appropriate distance from each other, when the tension cords 111 and 112 intersecting at the middle portion of the storage case 104 come close to each other and come into contact with each other, they are disengaged. Since the vehicles run in opposite directions, there is a problem that damage due to friction becomes very severe. Therefore, as a result, it is necessary to displace each of the two pulleys at both ends of the storage case in the direction of the rotation axis, which makes it difficult to make the screen door thin.

[0006]

The technical problem of the present invention is to obtain an accurate translation of the operation frame as previously proposed in a screen door in which the net is retractable or openable in a retractable or accordion type. When attaching the parallel moving mechanism, by appropriate tensioning of the string, the turning direction of the string and the running direction of each string in the parallel running part are made the same,
Thereby, the friction between the tension cords is reduced, and the members corresponding to the plurality of pulleys can be shared, or can be disposed close to the thickness direction of the screen door, and as a result, the screen door can be thinned. It is in.

[0007]

In order to solve the above-mentioned problems, the opening-and-closing screen door of the present invention is housed in a storage case constituting one side of a screen frame and can be pulled out for stretching. In the screen door, an operation frame for opening and closing operation is attached, and this operation frame can be moved along the guide frame.
One end of a pair of tension cords is attached to the lower end of the operation frame, respectively, and the tension cords are led out to the opposite side in the moving direction of the operation frame, and the lower ends of the storage case and the frame receiver located on the opposite side, respectively. Wrapped around the deflecting element provided in the section, guided to the upper end of the storage case and the frame receiver, wrapped around the deflecting element provided on the upper end thereof, and further, the upper end of the storage case and the frame receiver. The above-mentioned tension cords from the respective diverters are wound around the diverters at the upper end of the frame receiver and the storage case facing each other, and then folded, and the ends of the tensioners are fixed to the upper end of the operation frame, respectively. It is assumed that.

Further, according to the present invention, one end of a net which can be expanded and contracted in an accordion style by applying a large number of pleats is fixed to a storage case constituting one side of a screen frame,
At the other end of the net, an operation frame for opening and closing operation is attached, and in a screen door in which the operation frame can be moved along the guide frame, one end of a pair of tension cords is attached to a lower portion of the operation frame, respectively. The tension cord is led out to the opposite side in the moving direction of the operation frame, and is wound around a storage case and a deflecting device provided at a lower portion of the frame receiver located on the opposite side, respectively, and then the upper ends of the storage case and the frame receiver. , And wrapped around the diverter provided at the upper end thereof, and further, the tension cords from the diverter at the upper end of the storage case and the frame receiver are connected to the frame receiver and the upper end of the storage case facing each other. Wrap around the diverter of the part and fold it back, fix the ends of those cords to the upper part of the operation frame, respectively.
A tension cord, which is fixed to an upper or lower part of the operation frame and is wound around the turning element of the storage case, is slidably attached to the net along with the net.

[0009]

In the opening / closing screen door having the above-mentioned structure, the posture of the operation frame is restricted by the tension cord. Therefore, it is attempted to open and close the net by manually operating an arbitrary portion of the operation frame, for example, near one end thereof. In this case, the force is transmitted to the other half of the operation frame through the tension cord, which is equivalent to operating both ends of the operation frame by hand, and the operation frame is accurately translated in parallel. Thus, the opening and closing operation can be stably performed.

[0010] In this case, at the turning portion of the tension cord at the upper end of the storage case and the frame receiver opposed thereto, the tension cord moves in the same direction when the operation frame is moved. There is no need to provide them separately, and a single diverter can be used for the two tension cords. Since it is a direction, there is almost no damage due to friction. Therefore, it is not necessary to separate the traveling positions of the tension cords, and as a result, the screen door can be made thin.

In the case of an accordion-type net which can be expanded and contracted by applying a large number of pleats, the net is very easy to bend, so it is necessary to prevent the net from loosening naturally or loosening due to wind or the like. Of the above-described tension cords, an end portion is fixed to the upper or lower part of the operation frame, and a tension cord of a portion to be wound around the diverter of the storage case is attached to the net, and the tension cord is slidable on the net. Because it is attached,
The slackening of the net can be prevented and the stretched state can be stabilized.

[0012]

2 and 3 show the construction of a parallel moving mechanism in the openable screen door of the present invention. In the first embodiment shown in FIG. 2, an openable and closable net 2 is attached to a square screen door frame 1. FIG. However, as the net 2 in the opening / closing screen door, any opening / closing type net, such as a winding type or an accordion type, which is housed in a storage case on one side and can be pulled out for stretching is used. it can.

The screen frame 1 has one side connected to the net 2
The upper and lower ends are connected to upper and lower guide frames 5 and 6, and the other ends of the guide frames are located at opposite ends opposite to the storage case 4. The frame receivers 7 are connected and formed into a square shape by these. The operation frame 8 for opening and closing operation is attached to the end of the net 2 which can be pulled out from the storage case 4 for stretching, and the operation frame 8 is connected to the guide frames 5 and 6.
It is guided so that it can move along.

One end of a pair of tension cords 11 and 12 is attached to the lower end of the operation frame 8 as a parallel movement mechanism for restricting the attitude of the operation frame 8 and constantly moving the operation frame 8 in parallel. The tension cords 11 and 12 are led out to the opposite sides in the moving direction of the operation frame, that is, to the storage case 4 side and the frame receiver 7 side, respectively, and are turned at the lower ends of the storage case 4 and the frame receiver 7, respectively. After being wound around the children 13 and 14, it is guided to the upper ends of the storage case 4 and the frame receiver 7, and is wound around the turning elements 15 and 16 provided at the upper ends thereof. String 1 from 16
1 and 12 are connected to each other by the other diverter, that is, the diverter 1 at the upper end of the frame receiver 7 and the storage case 4 facing each other.
Wrap around 6 and 15 and fold them, and then put their tension strings 11 and 1
2 are fixed to the upper end of the operation frame 8, respectively.

In the case of a winding type in which the net 2 wound around a roll is pulled out for stretching, the storage case 4 constituting one side of the screen door frame 1 is partially provided with a roll having a net outlet. When formed in a box shape and provided with a large number of pleats in a zigzag shape to make it expandable and contractable in an accordion manner, the net is provided with a groove-shaped net accommodating portion for accommodating the net 2. Is fixed to the inner bottom portion of the net accommodating portion, and when the net 2 is accommodated in the recessed net accommodating portion by operating the operation frame 8, the operation frame 8 covers the storage case 4. It is configured as follows.

Each of the above-mentioned deflectors can be formed by a rotatable pulley, but can also be formed by a fixed guide member made of a synthetic resin material or the like having a small frictional resistance with the tension string. In particular, each of the deflectors 15 and 16 provided at the upper end portions of the storage case 4 and the frame receiver 7 are wound around two strings 11 and 12, respectively. It can be formed by one deflector, or it can be formed by a separate deflector. In addition, the turning elements 15 and 16 provided at the upper ends of the storage case 4 and the frame receiver 7 are not necessarily required to be provided in the storage cases 4 and 16.
The upper and lower guide frames 5 fixed to the upper and lower ends of the storage case 4 and the frame receiver 7 need not be attached to the frame receiver 7 itself.
6 can also be attached.

In the opening / closing screen door having the above configuration,
The posture of the operation frame 8 is constrained by the tension cords 11 and 12. Therefore, when an arbitrary portion of the operation frame 8 such as the vicinity of one end thereof is to be manually operated to open and close the net 2, the force is required. Is transmitted to the other half of the operation frame 8 through the tension cords 11 and 12, and as a result, the operation of the entire operation frame 8 is performed by hand. Opening and closing operations can be performed stably.

In this case, in the turning portions of the tension cords 11 and 12 at the upper end of the storage case 4 and the frame receiver 7 opposed thereto, the tension cords 11 and 12 run in the same direction when the operation frame 8 moves. It is not necessary to separately provide the diverter for the tension cords 11 and 12, and a single diverter 15 or 16 can be used for each of the two tension cords 11 and 12, and the tensioner 11 can be used before or after the diverter. , 12 come into close contact with each other, and since they move in the same direction, there is almost no damage due to friction. Therefore, it is not necessary to separate the traveling positions of the tension cords 11 and 12, and as a result, the screen door can be made thin.

In the parallel running portion where the tension cords 11 and 12 are wound around the deflecting members 15 and 16 at the upper ends of the storage case 4 and the frame receiver 7, the tension cords travel in opposite directions. Since the cords do not intersect in the portion and the string spacing can be given a relatively large margin, friction and wear due to the contact of the cords do not occur.

On the other hand, a second embodiment of the present invention shown in FIG.
An accordion-type net 22 is used which can be expanded and contracted by applying a large number of pleats. One end of the net 22 is fixed to a storage case 24 which constitutes one side of a screen door frame 21, and the other end of the net 22 is used for opening and closing operation. The operation door 28 is attached, and the operation door is movable along the upper and lower guide frames 25 and 26. The screen door is provided with a parallel movement mechanism similar to that of the first embodiment described above. A tension cord 31 having one end attached to the lower part and wound around a deflection element 33 at the lower part of the storage case 24, and a tension cord 32 wound around the deflection element 35 at the upper end of the storage case 24 and connected to the upper part of the operation frame 28
Are respectively connected to the middle positions of the lower half and the upper half of the operation frame 28, and the tension cords 31 and 32 are inserted into the net along with the net 22.
2 so as to be slidable.

Along with setting the attachment positions of the tension cords 31 and 32 to the operation frame 28 at an intermediate position between the lower half and the upper half of the operation frame 28, they are provided at the lower end of the storage case of the first embodiment. The deflecting element 33 corresponding to the deflecting element 13 is provided at a position where the tension cord 31 passes in the lower half of the storage case 24,
Further, the tension cord 32 is moved to the operation frame 2 at an intermediate position of the storage case 24.
A turning element 37 is separately provided in the storage case for turning to the 8 side.

The parallel movement mechanism in the openable screen door of the second embodiment having the above-described structure is the same as that of the first embodiment in the screen door having the accordion-type telescopic net 22 by applying a large number of pleats. Although the accordion system functions in substantially the same manner, it is necessary to prevent a natural slack of the net or a slack due to wind or the like. However, as described above, the tension cord 31,
32, an end portion is fixed to the upper or lower portion of the operation frame 28, and a tension portion of a portion to be wound around the transflector of the storage case 24 is attached to the net 22, and the tension portions 31, 32 slide on the net. Since it is attached as possible, the slack of the net 22 can be prevented and the stretched state can be stabilized.

[0023]

As described in detail above, according to the opening / closing screen door of the present invention, it is possible to obtain an accurate parallel movement of the operation frame in the screen door that can be freely opened and closed in a retractable or accordion type. When attaching a parallel movement mechanism,
Appropriate tensioning of the cords makes the turning position of the cords and the traveling direction of each cord in the parallel running part the same, thereby reducing the friction between the cords. , So that the screen door can be made thinner.
