TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontal screen door that is attached to an opening of a building for insect control and opens and closes an accordion-type telescopic net horizontally.
[0002]
[Prior art]
Conventionally, as shown in FIG. 4, this type of horizontal draw screen door is installed at the opening of a building for the purpose of insect repellent or the like, and the net 1 is made to be able to expand and contract in an accordion type, and is pleated and alternately inverted. It is folded in the direction and can be opened and closed left and right by folding. The frame 2 for holding the net 1 openably and closably has a rectangular shape and includes an upper rail 2a and a lower rail 2b, and side frames 2c and 2d mutually connected to both sides of the upper and lower rails 2a and 2b. It is fixed around the opening of the building and is molded of aluminum or synthetic resin.
[0003]
The upper and lower ends of the net 1 are held so as to be fitted into the upper and lower rails 2a and 2b, and the upper and lower ends of the operation frame 3 attached to the movable side end of the net 1 are guided by the upper and lower rails 2a and 2b. Are moved smoothly.
A plurality of wires 4a to 4d are inserted in parallel in the horizontal direction in the net 1 so as to keep the wires 4a to 4d in a constant tension state, and the folded portion of the net 1 is expanded by the action of wind pressure or the like. The swelling (flexion) prevents the upper rail 2a and the lower rail 2b from coming off.
[0004]
One end of each of the plurality of wires 4a to 4d is individually fixed to the operation frame 3, and of these wires 4a to 4d, other wires 4b to 4d except for the wire 4a located at the upper end are attached to the side frame 2c. It is wound around the diverters 5a to 5c and guided to the upper part of the side frame 2c, and is wrapped around the diverter 6 arranged on the upper part of the side frame 2c together with the wire 4a located at the upper end, and the wires 4a to 4d are grouped together. 2c, and a weight 7 is attached to the other end.
Accordingly, the weight 7 applies an operating force to the operation frame 3 in the opening direction, and the tension applied to the wires 4a to 4d stabilizes the posture of the net 1 and prevents the net 1 from bulging due to wind pressure or the like. It has become.
[0005]
[Problems to be solved by the invention]
By the way, in the horizontal screen door as described above, when the weight 7 is provided, in order to prevent the bulging of the net 1 due to the action of wind pressure or the like, it is necessary to increase the weight 7 and increase the tension acting on the wires 4a to 4d. There is.
However, when the weight 7 is made heavy, when the net 1 is automatically opened, the operation frame 3 gradually accelerates and collides strongly with the side frame 2c at the open end, generating a loud impact sound, and each part may be damaged by the impact. There is a problem that there is.
[0006]
The present invention has been made in view of the above-described problems, and an object of the present invention is to prevent the operation frame from strongly colliding with the side frame at the open end while increasing the wire tension. To provide a horizontal screen door.
The above and other objects and novel features of the present invention will become apparent from the description of the present specification and the accompanying drawings.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, a horizontal draw screen door according to the present invention is a net that expands and contracts in an accordion style by being alternately bent in a reverse direction in a large number of parallel and equally bent bent portions, and is laterally drawn into a frame body. The base end of the net is fixed to the frame body, an operation frame for opening and closing operation that slides along the frame body is attached to the tip of the net, and one end is connected to the net base end. A plurality of wires individually fixed to the frame on the side are inserted into the net, guided by the guide members provided on the operation frame into the operation frame, and the other wires in the operation frame are It is characterized in that a weight is hung at an end, and a roller is pivotally supported as the guide member on the operation frame.
[0008]
Therefore, in the present invention, the net is automatically opened by the weight acting on the operation frame via the wire. In this case, the force acting on the operation frame is consumed not only for folding and opening the net but also for moving the weight itself together with the operation frame, so that the acting force of the weight acting for opening the net is reduced, The operation frame does not strongly collide with the side frame at the open end of the net.
As a result, a heavy weight can be used, so that the wire tension due to the weight can be increased, and the swelling of the net due to the action of wind pressure or the like can be reliably prevented.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In describing the embodiments, components having the same function are denoted by the same reference numerals.
1 is a partial cross-sectional view of a horizontal screen door according to an embodiment of the present invention when viewed from the front, FIG. 2 is a cross-sectional view taken along line AA of FIG. 1, and FIG. It is a side view.
[0010]
The horizontal draw screen door shown in FIGS. 1 to 3 has a stretchable net 11 that is openably and closably mounted in a frame 12 fixed around a building opening. The net 11 is constituted by, for example, an insect repelling net which is made to be capable of being extended and contracted in an accordion manner by alternately bending in a reverse direction by applying a large number of pleats, and opening and closing right and left by the folding.
The frame body 12 which holds the net 11 so as to be openable and closable has a rectangular shape as a whole by an upper rail 12a and a lower rail 12b, and side frames 12c and 12d mutually connected to both sides of the upper and lower rails 12a and 12b. , Aluminum or synthetic resin.
[0011]
The fixed side end (base end) of the accordion-type telescopic net 11 is fixed to the side frame 12c, and the movable side end (operating end) of the net 11 slides left and right along the upper rail 12a and the lower rail 12b. An operation frame 13 movably held for an opening and closing operation is attached.
A latch 15 for holding the operation frame 13 in the closed position is mounted on the side frame 12d, and a latch 15 is locked on the operation frame 13 to lock the screen door in the closed position. A hole 13a is formed.
[0012]
A plurality of wires 14a to 14d are guided in parallel by a plurality of eyelets 16 fixed to the side frame 12c and the operation frame 13 in the upper and lower portions of the net 11 and in the lateral direction therebetween, and are inserted in parallel. 14d is held in a constant tension state by a weight 18 described later, and the net 11 is prevented from expanding and coming off from the upper rail 12a and the lower rail 12b by the action of wind pressure or the like.
One end of each of the wires 14a to 14d is individually fixed to the side frame 12c. The wires 14a to 14d are collectively wound around a roller 17 mounted in the operation frame 13 and guided into the operation frame 13. And a weight 18 is hung at the other end. In the figure, reference numeral 19 denotes a muffling ring which is provided around the outer periphery of the weight 18 to mitigate an impact caused by contact between the weight 18 and the inner wall of the operation frame 13 and to prevent generation of an impact sound. These wheels are attached to the upper end of the frame 13 and run in the upper rail 12a.
[0013]
Since the horizontal screen door is configured as described above, an operating force in the opening direction is applied to the operation frame 13 by the weight 18, and the posture of the net 11 is stabilized by the tension applied to the wires 14a to 14d. The swelling of the net 11 due to the action of wind pressure or the like is prevented.
Since the acting force of the weight 18 acts in the opening direction of the net 11, when the hook 15 is removed in a stretched state of the net 11, that is, in a closed state, the net 11 is moved through the operation frame via the wires 14a to 14d. Due to the acting force of the weight 18 acting on the 13, the weight 18 automatically moves toward the side frame 12 c together with the weight 18 suspended inside the operation frame 13, whereby the net 11 is opened.
[0014]
In this case, since the acting force of the weight 18 is consumed not only for folding and opening the net 11 but also for moving the weight 18 itself, it is necessary to release the net 11 to the operation frame 13. The acting force is reduced, and it is possible to prevent the operation frame 13 from strongly colliding with the side frame 12c at the open end.
As a result, the weight of the weight 18 can be made relatively large, so that the tension of the wires 14a to 14d by the weight 18 can be increased, and the swelling of the net 11 due to the action of wind pressure or the like can be reliably prevented. And the insect repellent effect can be further improved.
[0015]
As described above, the horizontal screen door according to the embodiment of the present invention has been described in detail. However, the present invention is not limited to the horizontal screen door described in the above embodiment, and is described in the claims of the present invention. Various changes may be made in the design without departing from the spirit of the invention.
For example, in the above embodiment, the roller 17 is used as the guide member, but a guide member made of a synthetic resin material or the like having a small frictional resistance with the wires 14a to 14d may be adopted.
[0016]
【The invention's effect】
As can be understood from the above description, according to the horizontal draw screen door of the present invention, since the weight is suspended in the operation frame, the acting force in the opening direction acting on the operation frame is due to the movement of the weight itself. Is also consumed, and the acting force of the weight acting on opening the net to the operation frame is reduced, so that the weight can be increased.
Therefore, the tension of the wire inserted into the net can be sufficiently obtained, and the operation frame can be prevented from strongly colliding with the side frame at the open end while reliably preventing the swelling of the net due to the action of wind pressure or the like. In addition, each part is not damaged by the generation of impact noise or impact.
