DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a four-sided framed door screen installed at an opening of a building such as a window frame.

[0002]

2. Description of the Related Art Conventionally, screen doors installed on a horizontally drawn sash frame or the like have a four-sided frame structure, and a net made of vinyl chloride or the like is pressed into a packing groove provided around the four-sided frame together with a rope-shaped packing. In general, they are stretched.

[0003]

However, the above-mentioned door-plate-shaped screen door requires skill in the net tensioning operation in the manufacturing process, discomfort that obstructs the field of view due to dirt during use, complexity of washing with water, or reduction of the screen door. Various problems such as annoyance that are permanently installed on the window frame even during unnecessary off-season such as winter season, and furthermore, the left and right glass sashes of the draw sash are overlapped at the center of the window frame, and ventilation ventilation from the left and right open parts When doing
There is also a problem that only one of the open portions can be covered. In addition, the net material used for conventional screen doors is that the weft yarns only cross the warp of a non-twisted single line made of vinyl chloride or the like sequentially in the front and rear direction. In order to minimize unraveling of the yarn at the hem of the net, the yarn is thick and strong.

Therefore, when this strong net is successively pressed into the packing groove together with the packing, considerable skill is required to provide tension without slack or flare. Even if you notice any loosening or flare after you have finished stretching the net and try to partially repair it locally, the rope-like packing pressed into the packing groove endlessly cannot be partially pulled out. You have to pull it out and start over, but if you try to tension the net by pulling off the net hem that has already been cut, the thread will loosen and loosen, so you will have to replace the net and re-tension it In some cases.

On the other hand, the above-mentioned vinyl chloride net yarn has a large coefficient of linear expansion, and therefore has a large expansion and contraction rate due to hot cooling, and is easily stretched and loosened. Therefore, it is necessary to pre-tension the net yarn to prevent loosening. is there. Because of that, the vertical screen door is bent by the net on both sides of the vertical frame and bent like a drum at the center,
In the middle part, it is necessary to arrange a center lining for preventing deflection,
As a result, in addition to the problem of obstructing the view, there is also a problem that the manufacturing cost increases. In order to replace the entire aging screen door with a new one, D.I.
It Yourself, a general merchandise retailer (hereinafter “DI
Y ". )], Etc., the door-plate-shaped screen door of the finished product with the net stretched is sold in stores, and this is a completed assembled product because the meshing work is difficult and troublesome as described above. However, since large-sized items cannot be carried by ordinary passenger cars, the delivery must be requested to the store side, and the fare increases, which reduces the purpose of selling in DIY by half.

Further, since the thick yarn net is easily conspicuous, the degree of visibility is reduced, and there is a problem that visibility becomes worse as the net becomes dirty. To clean the dirty net with water, a screen door must be used. Must be removed from the window sill. This is difficult and cumbersome, and in the off-season when no screen door is required, removing it from the window frame and keeping it clean will keep the area around the window clear. Many. In addition, since the cleaning work is difficult and troublesome as described above, it is often installed permanently on a window frame all year round, and the stain on the net further progresses, making the view more and more unclear, and There is also a problem that the life is shortened.

The present invention has been made to solve the above-mentioned problems, and a new work and an existing screen door are subjected to post-processing so that the screen work can be performed safely and easily from the indoor side. Eliminates the need for work skills. In addition, net cleaning can be performed by simply removing the screen without removing the screen frame from the window frame, and in the off season, removing only the screen while leaving the empty screen frame in the window frame. In addition to improving visibility and extending the life of the net by cleaning and storing it, the screen door is completely extended to the entire window frame regardless of the open state of the right and left glass shojis of the sash, and the insect repellent action is completely completed. It is another object of the present invention to provide efficient ventilation and ventilation.

[0008]

For this purpose, a flexible bristle removably engageable with a flexible net is provided around the periphery of a four-sided frame set in the form of a door plate, such as a window frame, installed in an opening of a building. Is at least two or more ridges having a T-shaped or L-shaped cross-section extending integrally from the fastener or the hoop,
A fastener that is continuously provided in the longitudinal direction of the material and that can be engaged with the mesh by pushing the mesh into the channel surrounded by the hoop and the ridge is fixedly provided. The fastener and the mesh edge of the flexible mesh are detachable. To facilitate the meshing operation and the cleaning operation with the net removed. In addition, in the draw sash, when the left and right glass shojis are overlapped at the center of the opening and ventilation is performed from the openings on both sides, two separate screen doors inside and outside are slidably constructed in double. The screen door is drawn so as to cover the entire window frame opening.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention, when implemented, is applicable to both net screens constituted by new-type cross-section frames by manufacturers and existing net doors already in operation. A mesh of Russell weave or tricot weave, etc., woven so that warp and weft yarns made of polyester are entangled with each other. In the case of a new product, a C with a lip to which the above-mentioned fastener can be attached
In the case of the existing screen door frame, a slit is formed in the shape of a channel in section and a fastener is inserted into this slit.
It is a structure in which fasteners are fixedly arranged around the four-sided frame using double-sided adhesive tape, etc.The mesh edge made of polyester or the like is engaged with these fasteners, and only the extra length of the mesh is cut off with a cutter. For existing screen doors, pull out the packing and remove the net. This operation is possible without removing the existing screen door from the window frame, and is very easy and safe. The present invention can also be applied to a screen door fixedly disposed in a narrow opening. For example, it is only necessary to fix and cover a door plate-shaped screen door provided with a net by the above-described method on a square framed frame of a ventilation opening with a ventilation gallery. In addition, to cover the entire window frame opening of the sliding window and complete the insect repellent action irrespective of the open state of the glass shoji, a telescopic screen door with two inner and outer double door plates is used. The window frame is laid horizontally on the screen door rail, and the inside and outside screen doors are drawn on the screen door rail to cover the entire opening.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the illustrated embodiments. FIG. 1 shows an embodiment in which a four-sided frame is formed as a new section as a new product, and upper and lower frames (2) and (3) and a vertical frame (4).
Are provided with slits (5) each having a C-shaped cross section with a lip, and a fastener (6) is inserted into the slit (5). The zipper (6) has resin thin hairs (6b) implanted in a cloth hoop (6a) made of polyester or the like,
The cloth hoop (6a) is inserted into a hoop holder (10) having a slit-like cross section made of resin, and the hoop (6a) is inserted.
Both side edges of a) are held so as not to come off the slits of the hoop holder (10). The above-mentioned fastener fine hair (6b) is used either as a round grip shape having a bristle tip whose diameter is larger than the fine hair wire diameter or a Velcro fastener (FIG. 3 to FIG. 6) having a bristle-shaped bristle tip. It is possible. Fastener fine hair (6
The mesh of the polyester net (1) is entangled with the mesh of b), and the net of the remaining length is cut off with a cutter to complete the netting work.

As described above, the net (1) is woven so that the warp and the weft are entangled with each other, so that the warp and the weft can be unraveled even if any part is cut, such as Russell weave or tricot weave. It is a net, and the acrylic coating has the effect of further preventing the warp and weft from unraveling and the net from expanding and contracting due to heat cooling. As a result, even if loosening or flare is found after completion of the meshing work, the mesh edge can be partially removed from the zipper and re-tensioned. Since it is small, it is not necessary to provide a strong tension as in the conventional net, and when receiving wind pressure, it is necessary to have a degree of tension that does not bend and bulge.

FIG. 2 is a perspective view of the inside of a frame group of a conventional existing screen door, and a fastener (8) is fixedly provided around the periphery of the four-sided frame with a double-sided adhesive tape. As before, the fastener (8) has fine hairs (8b),
The mesh mesh is removably entangled with the mesh. A packing groove (11a) for fitting the rope-shaped packing (11) is provided around the outer periphery of the four-sided frame, and if the net (12) and the packing (11) are removed from the packing groove (11a), the work is completed. Is safe and easy because it can be performed from the indoor side with the screen frame set removed from the window frame and installed. 3 to 6 are enlarged views of the fastener. The hoops (6a) and (7a) in FIGS. 3 and 4 are made of a cloth made of polyester or the like, and are made of resin, for example, fine hair made of polypropylene or nylon. The fine hair in FIG. It is molded into a grip. The fine bristles in FIG. 4 are Velcro fasteners whose tips are bent. Cloth hoops (6a) and (7a) of the fastener are structured so that both edges of the hoop are held by a resin hoop holder (10) and do not deviate.

The fine wool is obtained by sewing a resin thread into a cloth hoop and then cutting and heat-treating a portion protruding from the cloth surface. The fasteners (8) and (8) shown in FIGS.
(9) is a fastener made of nylon or synthetic rubber in which the hoop, the hoop holder, and the fine hair are integrally formed. The fine hair (8b) is formed so as to be inclined with respect to the hoop (8a) so that the mesh thread to be engaged is not easily pulled off. The fine bristles (9b) in FIG. 6 are shaped such that their tips are L-shaped or T-shaped, and are more difficult to disengage with the net.

FIG. 7 is a cross section of a separate fastener having a different structure from the fastener. In the fastener, an independent needle is protrudingly implanted on the hoop surface, whereas the fastener (13) of this embodiment is an extruded product of synthetic rubber or synthetic resin, and the independent needle of the hoop is formed. Are formed as continuous ridges (13a) having a T-shaped cross section. The ridge (13a) is composed of a web (13c) and a flange (13d) integrally extending from the hoop (13b), and the adjacent ridge (13a).
Are in contact with each other so that the flanges (13d) are pressed against each other. FIG. 8 is a cross-sectional view of the shape of the fastener (13) before the application, that is, the extrusion molding. Since extrusion cannot be performed in a state where the flanges are pressed against each other so as to repel each other, the hoop (13b) is bent in advance, and extrusion is performed in a state where a gap is secured between adjacent flanges (13d) extending from the web (13c). When the fastener is installed, the hoop (13b) is forcibly flattened, that is, inserted into the slit (5) of the aluminum mold material, or the bottom surface of the hoop (13b) is adhered to the frame surface with an inner surface adhesive tape. (13
Since b) becomes flat, the opposing side edges of the hoop (13b) are pressed against each other, and at the same time, the flanges (13d) are pressed against each other so that they repel each other.

As shown in FIG. 7, the mesh edge is formed by attaching a flange (13d) to the channel (14) surrounded by the web (13c) and the flange (13d) together with the mesh (1) with a spatula or a fingernail. At the same time, the mesh end is housed in the outer channel (14), and the cut end of the mesh is concealed in appearance to provide a clean fit, and the mesh edge is double overlapped on all four sides to form a flange (13d). ), The structure can withstand external pressure such as wind pressure. When the hard fine wire is pushed into the channel (14) together with the net so that the fine wire does not fall out of the channel (14), the net can be further strongly engaged and held. Further, in contrast to the structure in which the mesh mesh fits with the independent needle (fine hair) in the fastener, the fastener (1
3) also has the effect of being able to hold the engagement regardless of the size of the mesh, thereby reducing damage to the mesh yarn. Further, the shape of the top flange of the ridge (13a) may be a round head without having a T-shaped cross section.

FIG. 9 is a state diagram when external pressure such as wind pressure is applied to the mesh (1) engaged with the fastener (8).
When an external pressure is applied to the net in a direction perpendicular to the net, most of the load is applied in the in-plane direction because the mesh yarn is flexible and internal stress in a direction opposite to the external pressure, i.e., out of the net plane, cannot occur. Only the tensile stress that is pulled in the direction of a certain central portion, most of the fastener fine hair (8b) engaging with the net edge is subjected to shearing force (V
S), and the component force (VP) for peeling off from the hair foot is very small. Since the mesh edge is entangled and engaged with the zipper hairs on all four sides, the mesh edge is firmly engaged with the fastener so that the mesh edge is not peeled off even by external pressure such as wind pressure.

FIGS. 10 to 15 show that the entire door opening of the sliding window frame is covered with a screen using the door-plate-shaped screen door structure of the present invention, and the insect repellent action is completely independent of the open state of the glass screen. It is an example of another door-like screen door which has been made possible. In FIG. 10, the vertical sectional view and FIG. 11, the horizontal sectional view, the screen door (15) is two separate door-panel screen doors (1).
5R) and (15L), and are slid horizontally to form a double sheet-like door.

That is, the inner and outer screen doors (15R), (15
Each of the opposed vertical stairs (16) and (18) and the vertical stairs (17) and (19) of L) are configured to mutually embrace each other. Doors (20), (21), (22), and (2) are located at the lower ends of the vertical and horizontal screen doors (15R) and (15L).
3) are arranged respectively, and the inner door (15L)
0) and (21) are on a window frame screen rail (28), and one door roller (22) of an outer screen door (15R) is an inner screen door lower frame (3).
On the guide rail (35 ') branching from 5), the other door rollers (23) are fixed to the lower end of the vertical frame (17), and are slidably mounted on the window frame net rail (28), respectively. I have.

In the vertical sectional view of FIG.
Guide rails (33 ') and (35') are respectively branched downward and upward from the upper and lower frames (33) and (35) of the L) so as to protrude into an L shape. Outer screen door (15R) upper and lower frame (3

(35 ') so as to be slidably guided in the longitudinal direction of the material. Even if the outer screen door (15R) is slid with the inner screen door (15L), the upper and lower frames (32) are not damaged so that the insect repellent action is not impaired. ), (34) flanges (32 '), (3)
4 ') extends close to the upper and lower window frames (31) and (30) to keep the gap small. The door rollers (20) and (21) of the inner screen door (15L) are on the screen door rail (28), and one door roller (22) of the outer screen door (15R) is a lower frame (35).
The other door roller (23) is installed on the branch rail (35 ') so as to freely roll on the screen door rail (28).

FIG. 12 shows left and right screen doors (15R) and (15R).
L) and extend it to the entire window frame.
5) and (26) are overlapped at the center, and the left and right open parts (3
6) shows a state in which ventilation ventilation is performed. In the case of a single screen door as in the related art, there is a case where inconvenience occurs because only one of the open portions can be covered.
For example, in a sickroom where air conditioning is not performed, when two beds are arranged side by side toward a window and the glass sliding door is drawn to either side, it is uncomfortable for the bed on the side where ventilation is not possible In addition, there is an obstacle such as rearranging dance on the side of the inner glass shoji (26) in the general room, which makes it difficult to open and close. Therefore, when the outer glass shoji (25) is opened and ventilated, the insect repellent effect is impaired. May be That is, FIG.
In 1, the outer glass shoji (25) has a considerable step between the vertical frame surface and the glass surface (G), so the insect repellent packing (24) of the screen door does not reach the glass surface (G), and a vertically long gap is formed. Is disadvantageous. For this purpose, the outer glass shoji (25) must be fully opened and the door frame (25 ') must be moved at a position where it comes into contact with the insect repellent packing (24). Therefore,
If the entire window frame opening is covered as in the present invention, a complete insect repellent action can be obtained irrespective of the open state when using glass.

FIGS. 13, 14 and 15 are front views showing the inside of the screen door of the present invention. FIG.
R) and (15L) are integrally formed like a single door-panel screen door, FIG. 14 is a drawing showing a process of overlapping or drawing expansion, and FIG. 15 is a drawing showing a state where the entire window frame is expanded. Since the embodiment of the present invention is configured as described above, the network (1)
As shown in FIG. 15, as described above, it is possible to remove the fastener from the fastener and perform flush cleaning and replacement repair easily and safely from the guide side as described above. If the net (1) is removed in the off-season and the inside and outside screen doors are overlapped, the appearance becomes a single empty screen door frame and the view can be made clear. Further, the conventional door-plate type screen door does not have a sunshine adjustment function and a blindfold shielding function. However, the screen door of the present invention has a thin mesh mesh with light shielding and blindfold from the viewpoint of easy replacement of the net and easy washing with water. Since a net having a function can be used, there is an effect that it can be used as a sunshade and a blind screen. When the sunshade screens are overlapped as shown in FIG. 13, the shading rate can be further increased, and ventilation can be performed while shading is performed.

In the above-mentioned embodiment, the above-mentioned screen door is installed by attaching upper and lower guide rails to the inner wooden frame of the sash, and the screen is replaced with a mesh-like mesh. If the lace curtain is stretched, it can be used as a screen with a curtain function.

[0023]

As described above, for a screen door made as a new cross section, the cost can be reduced for the manufacturer, and the screen door that is sold over the counter for DIY or the like can be knocked down and packed in a box for general passenger cars. In addition to the ease of transport, the frame assembly and netting work is simple and requires no skill, so the DIY sales objectives, ie, netting work costs at the manufacturer, curing costs for large-sized assembled products, and curing packaging costs. The advantage that the selling price can be reduced because the transportation cost of the assembly with poor transportation efficiency and the cost of the sales floor area at the store occupied by the assembled product are improved.

Further, as described above, the existing screen door can be safely modified from the indoor side during use, and even if the net becomes dirty or damaged during use, it can be removed from the indoor side optionally and washed with water. Cleaning or replacement repair can be performed. Furthermore, in the off-season such as the winter season, leaving the empty screen door frame in the window frame and removing and storing only the screen will save the life of the screen and also improve the visibility. is there. In addition, by making the inner and outer two screens that can be pulled together, the glass screens are overlapped in the center of the window frame, and when performing efficient ventilation and ventilation from the open sides on both sides, the screen door is placed over the entire window frame opening. Insect repellent action can be obtained regardless of the open state of the glass shoji by expanding, and by selecting the net material,
It has the effect that it can be used as light shielding and blindfold.
