Description

  The present invention relates to a screen door in which a net attached to an opening of a building for the purpose of preventing insects and the like can be easily detached from the indoor side.

  In recent years, in order to prevent the insect screen doors installed in middle- and high-rise apartments from falling and to facilitate maintenance, the insect screen doors are fixedly installed in the building opening frame, and the net is washed from the indoor side into the screen door frame. It is required to be easily detachable for replacement, and various means for simplifying it have been proposed, so it can be used on the outdoor side of a screen door frame like a screen door used in a general house. It is desired that a net to be fixed can be attached / detached or replaced by a simple operation from the indoor side of the screen door frame.

  However, since the net of the insect screen door prevents insects from entering the house, it can be opened and closed by installing it on the outermost side of the building opening and installing the shoji on the indoor side. Sometimes it is necessary to prevent insects from entering indoors and to attach and detach the net easily and quickly with the shoji open. And, as a means for attaching a net that can meet such demands, a commonly used hook-and-loop fastener is extremely desirable in terms of the ease and operability of attaching and detaching operations, but the problems described below also occur when it is used. There is.

  First, in the screen door, in order to enable the net to be removed from and attached to the screen door frame from the indoor side, the net door can be attached and detached from the indoor side with a hook-and-loop fastener from the indoor side has already been proposed in Patent Document 1 and the like. ing. In this type of proposal, one engaging member (surface adhesive tape, surface fastener, etc.) is attached to the inside of the screen door frame with an adhesive, and the other engaging member attached to the periphery of the insect net is It can be detachably attached to one engaging member of the screen door frame.

  However, a durable screen door frame, which is generally formed of an aluminum-based material, is installed in a part of a building that is exposed to direct sunlight. In midsummer, it is burned when a human body comes into contact with it. The temperature becomes high, and it is placed under extremely low temperatures in the severe winter season. Further, during heavy rain, it is placed in a harsh environment where the fixed portion of the net is exposed to rainwater through the eyes of the net. Therefore, when the hook-and-loop fastener is directly attached to the indoor surface side of the screen door frame with a double-sided adhesive tape or other adhesive, the durability of the adhesive in the environment can be maintained over a long period of time. There is a problem in terms of whether or not.

  Moreover, when repairing due to damage caused by deterioration of the adhesive in the screen door frame, it is not only possible to involve repair of the exterior of the building, etc., unlike replacement due to dirt or damage to the net itself. This is a relatively wide range of repairs, which can place a large economic burden on screen door users. It is possible to easily replace and clean the net using hook-and-loop fasteners. It is desirable to prevent damage to the screen door frame side.

  In addition to the problem of the durability of the adhesive, one hook-and-loop fastener piece is attached to the entire circumference of the indoor side of a rigid screen door frame made of metal or the like, and the other side through a reinforcing net frame at the periphery of the net. When attaching a hook-and-loop fastener piece to the hook-and-loop piece of the above-mentioned screen door frame so that it can be easily washed and attached to the screen door frame with flexibility, it is strong. In order to avoid scattering of the net with a frame due to wind or the like, it is desirable to fix the periphery of the net with a frame as strongly as possible to the screen door frame by using a hook-and-loop fastener that is excellent in joining force.

  However, when a hook-and-loop fastener having such a bonding strength is used, a gripping part for separating it from the hook-and-loop piece of the screen door frame is necessary in the peripheral portion of the framed net, and it should not be provided. In addition, if the peripheral part of the net is used as a gripping part for removing the hook-and-loop fastener together with the reinforcing net frame fixed to the net, it is not only easy to remove the net with the frame from the screen door frame. Damage to the reinforcing net frame fixed to the periphery of the net may occur frequently. Therefore, in the screen door, it is necessary to attach a configuration for easily and easily detaching the framed net attached to the screen door frame with a hook-and-loop fastener from the screen door frame.

Japanese Utility Model Publication No. 62-101998

  The technical problem of the present invention is desirable in terms of simplicity and operability of the attachment / detachment operation in order to enable the net to be easily and easily attached / detached from the indoor side to the screen door frame installed on the outdoor side rather than the shoji at the opening of the building. When using a hook-and-loop fastener, the above-mentioned screen door frame is generally placed in a poor environment. Therefore, an object of the present invention is to provide a screen door in which the hook-and-loop fastener is fixed to the screen door frame by means that can withstand the environment.

  Another technical problem of the present invention is that when a framed net is detachably attached to a screen door frame with the above-mentioned hook-and-loop fastener pieces, the joining force is won in order to avoid scattering of the framed net due to strong winds or the like. However, if such a hook-and-loop fastener is used, it will be difficult to easily and easily remove the net from the screen door frame. It is an object of the present invention to provide a screen door which is provided with a configuration for easily and easily separating from the screen door frame, and which can reduce the force required for detachment of the framed net.

  In order to solve the above-described problems, according to the present invention, the frame material is provided with a metal screen door frame that is squarely framed and is installed on the outdoor side of the shoji at the opening of the building. A flat portion for attaching the hook-and-loop fastener is formed on the indoor side, and the first hook-and-loop piece which is one of a pair of hook-and-loop fasteners is fixed to the flat portion, while the hook-and-loop fastener is attached to the flat portion of the screen door frame. The second hook-and-loop fastener piece to be fixed to the first hook-and-loop piece fixed to the screen door frame while fixing the net frame formed by connecting the flexible plate materials to the four circumferences thereof. Is attached to the net frame together with the net to form a framed net, and the net with the frame is attached to the screen door frame by joining the first and second hook-and-loop fastener pieces. And fixing the first hook-and-loop piece to the flat portion of the frame member in the screen door frame, along the both sides of the mounting position of the first hook-and-loop piece in the flat portion. A screen door characterized in that it is performed by pinching the side ends of the hook-and-loop fastener piece by inward bending.

  In a preferred embodiment of the screen door according to the present invention, the first hook-and-loop piece is laminated on the flat portion of the frame member of the screen door frame via an elastic sheet, and the fixing protrusion is bent to By fixing the elastic sheet side end together with one hook-and-loop fastener piece, the first hook-and-loop fastener piece is fixed, and if necessary, the fixing of the first hook-and-loop piece is fixed. The projecting ridge may be configured to have a press-contact ridge that cuts into the surface of the hook-and-loop fastener piece to be fixed along the tip.

  As described above, the first end of the hook-and-loop fastener piece is fixed to the flat portion of the frame member in the screen door frame by bending the fixing protrusions protruding along both sides of the hook-and-loop fastener piece. When mechanically performed by direct clamping, the hook-and-loop fastener piece is fixed to the screen door frame from a metal screen door frame that is placed in a harsh natural environment, such as when it depends on the bonding force of an adhesive or the like. The action of heating and cooling over a long period of time is directly transmitted to the adhesive of the hook-and-loop fastener piece, and there is no possibility of affecting the holding force of the adhesive, and the bonding force of the hook-and-loop fastener piece to the screen door frame is durable. Will be granted, and it will be possible to effectively use the screen door for a long term by cleaning and replacing the framed net.

  In another preferred embodiment of the screen door according to the present invention, the corner connecting members for joining the both ends of the four-round plate material constituting the net frame are respectively overlapped with the plate material end portions to be joined to each other at the corner portions. It is assumed that a plate member connecting portion orthogonal to each other and a gripping portion projecting to the inner corner side of the plate member connecting portion are joined, and the plate member connecting portion is joined to each of the plate member end portions orthogonal to each other, and the grip portion is connected to the plate member. By projecting on the inner net from the corner where the coupling part intersects, a gap for gripping the net frame is formed between the gripping part and the net below it. The

  When the first and second hook-and-loop fastener pieces joining the net frame to the screen door frame are removed, the corner portions of the net with the frame having a high distribution density of the hook-and-loop fastener are released at a time. Since a relatively large force is required, it is difficult to provide any separation assisting piece. Also, when removing a tape-shaped hook-and-loop fastener piece, it is always necessary to remove the minute portion gradually in the direction away from the end after removing the small portion from one end of the hook-and-loop fastener. Since it is performed continuously, it is easy to detach. On the other hand, it is relatively difficult to start detaching from the middle part of the tape-shaped hook-and-loop fastener piece because the area to be detached at first is large. There is a characteristic that there is.

  From this point of view, forming a finger-holding gap for gripping the net frame between the gripping part for removing the framed net and the net means that the corner angle of the framed net is Since the distribution density of the hook-and-loop fastener in the part is high, it is not appropriate, but conversely, part of the engaging elements of the first and second hook-and-loop pieces at the corners of the screen door frame and the net with frame is cut off. If a part of the engagement element is rendered non-functional by adjusting the direction in which the joining force between the screen door frame and the corner of the net frame is weakened, the upward movement operation of the finger inserted into the finger-hanging gap below the grip The net with the frame can be detached from the corner of the screen door frame at a portion very close to the portion where the joint strength between the screen door frame and the corner of the net frame is weakened, and the release of the hook-and-loop fastener is started. It becomes easier and the frame against the screen door frame Overall bonding strength can net itself can be maintained high.

  In another preferred embodiment of the screen door according to the present invention, an intermediate rail that divides the intermediate portion between the upper and lower frame members of the screen door frame in the horizontal direction is installed between a pair of vertical frame members, In addition, on the side facing the upper and lower partition areas in the screen door frame partitioned thereby, an intermediate beam plane portion corresponding to the first plane fastener mounting plane portion provided on the frame material of the screen door frame is provided. The upper and lower partition areas partitioned by the middle rail are formed by protruding protrusions for fixing the first hook-and-loop fastener along both sides of the mounting position of the hook-and-loop fastener piece in the middle rail plane portion. In addition, each of the above-mentioned nets with a frame is formed so as to be attached independently.

  The screen door provided with the above-mentioned middle rail is that the screen door according to the present invention basically facilitates cleaning and replacement by removing the net. This is also effective for making it possible to select the function of the net depending on the vertical position within the screen door frame.

  According to the screen door of the present invention described in detail above, when using a hook-and-loop fastener that is desirable in terms of ease of operation and operability for attaching and detaching the net from the indoor side to the screen door frame, the screen door frame is generally in a poor environment. Therefore, the hook-and-loop fastener piece is fixed to the screen door frame by pinching the hook-and-loop fastener piece by bending the fixing protrusion protruding from the screen door frame. The hook-and-loop fastener can be stably fixed to the screen door frame withstanding the environment.

  In addition, when attaching a net with a frame to the screen door frame with the above-mentioned hook-and-loop fastener piece, it is necessary to use a hook-and-loop fastener that is superior in joining force in order to avoid scattering of the net with the frame due to strong winds or the like. Even when such a hook-and-loop fastener is used, according to the configuration of the present invention, the framed net attached to the screen door frame can be easily and easily detached from the screen door frame. Thus, it is possible to obtain a screen door that can have a joining force for avoiding scattering of the net with a frame due to the like.

It is the perspective view which looked at the assembly state of the screen door which concerns on this invention from the room inner side. It is a partially broken perspective view which shows the state which attaches a middle rail between the left and right vertical frame materials in the screen door which concerns on this invention.

  The drawings show an embodiment of a screen door according to the present invention. In this screen door, as shown in FIG. 1, the frame material of the four laps is framed in a square shape and is installed on the outdoor side of the shoji at the opening of the building. A metal screen door frame 1 is used. The screen door frame 1 is configured by connecting both ends of each pair of vertical and horizontal frame members 2 and 3 and can be fixedly attached to a housing of a building, but can be freely opened and closed with a sash or the like provided on the housing. It can also be installed so as to be openable and closable along a rail provided on the outdoor side of the shoji. Note that the screen door frame 1 of FIG. 1 is illustrated as having a shoji of a building opening on the left front side, and is installed with the right front side facing the outdoor side of the building.

  With reference to FIGS. 1, 2 and 6, the configuration of the screen door frame 1 which is squarely framed by the vertical and horizontal frame members 2 and 3 will be described. The screen door frame 1 is a general-purpose durable aluminum-based material. As shown clearly in FIGS. 2 (a) and 2 (b), the vertical and horizontal frame members 2 and 3 of the screen door frame 1 are formed of other metal extruded shapes. 4 and 5 and net mounting extensions 6 and 7 which extend from the main body toward the inside of the frame and have flat surface mounting portions 6a and 7a for mounting surface fasteners on the indoor surface side. And. Since the main body portions 4 and 5 and the extending portions 6 and 7 of the frame members 2 and 3 are integrally formed, the main body portions 4 and 5 and the extending portions 6 and 7 are clearly separated. It was not prepared as a product.

  As can be seen from FIG. 1, at the corners connecting the both ends of the vertical and horizontal frame members 2 and 3, part of the main body portion 4 and the extending portion 6 at the upper and lower end portions of the vertical frame member 2 are cut off. Thus, the end 3a of the horizontal frame member 3 is inserted into the insertion groove 2a formed in the main body portion 4, and the vertical portion of the screw pocket 3b formed in the horizontal frame member 3 is inserted. The screen door frame 1 is rectangularly framed by connecting the vertical and horizontal frame members 2 and 3 at each corner portion by means such as screwing screws through screw holes provided in the inner wall 2b of the frame member 2. .

  On the other hand, the flat portions 6a and 7a provided on the extending portions 6 and 7 of the vertical and horizontal frame members 2 and 3 are detachably attachable to the frame members 2 and 3 as shown in FIG. 2 and 3, as shown in FIG. 2 and FIG. 3, the hook-and-loop fastener piece 10a is attached along both sides of the mounting position for attaching the first hook-and-loop fastener piece 10a which is one of the pair of hook-and-loop fasteners. Fixing protrusions 8 for fixing are bent inward from each other and protruded. The hook-and-loop fastener piece 10a is fixed by the fixing protrusions 8 as shown in FIG. 3A by arranging the hook-and-loop fastener pieces 10a on the flat portions 6a and 7a between the pair of fixing protrusions 8. In this state, the distal end portion of the fixing protrusion 8 is bent inward by a tool such as a pressure roller, and both side ends of the hook-and-loop fastener piece 10a are sandwiched between the flat portions 6a and 7a. Is.

  When the fixing protrusion 8 is bent and both side ends of the first hook-and-loop fastener piece 10a are sandwiched between the flat portions 6a and 7a, both sides of the hook-and-loop fastener piece 10a by the fixing protrusion 8 are provided. In order to more firmly fix the end, as shown in FIGS. 2 and 3, the fixing protrusion 8 is bitten into the surface of the hook-and-loop fastener piece 10a to be fixed along the tip portion. What is necessary is just to attach the press-contact protrusion edge 8a raised to the top. In addition, when necessary, when the fixing protrusion 8 is bent, the pressing contact edge is formed on the flat surface portions 6a and 7a facing the portion where the pressing contact edge 8a bites into the first hook-and-loop fastener piece 10a. It is also possible to increase the holding force of the fixing portion of the hook-and-loop fastener piece 10a by the fixing rib 8 by providing the concave portion 9 that receives the deformation portion of the hook-and-loop fastener piece 10a that is deformed into a concave shape by the biting of 8a.

  Further, as shown in FIG. 3 (b), the flat portions 6a and 7a of the frame members 2 and 3 in the screen door frame 1 are provided with a weather-resistant and heat-resistant elastic sheet 12 such as vinyl chloride, and the above. After laminating the first hook-and-loop fastener pieces 10a, the elasticity together with the first hook-and-loop fastener pieces 10a is obtained by bending the fixing protrusions 8 in the same manner as described above with reference to FIG. It is also possible to fix the first hook-and-loop piece 10a by sandwiching the side end of the sheet 12 between the flat portions 6a and 7a. In this case, since the elastic sheet 12 has heat insulation properties, even if an adhesive is used between the elastic sheet 12 and the hook-and-loop fastener piece 10a, heat conduction from the frame members 2 and 3 is limited. Therefore, the influence of heat conduction on the adhesive can be mitigated.

  The first hook-and-loop fastener piece 10a attached to the flat surface portions 6a and 7a of the extending portions 6 and 7 of the vertical and horizontal frame members 2 and 3 as described above is stretched with the net 14 for insect protection on the screen door frame 1. 4 and 6 for attaching the framed net 13 with the second hook-and-loop fastener piece 10b paired with the first hook-and-loop fastener piece 10a.

  The hook-and-loop fastener is generally configured as a plurality of hook-shaped and pile-shaped engaging elements 11 that can be joined to each other, and the first and second hook-and-loop fasteners. Any of them may be selected as the pieces 10a and 10b. However, for example, as the first hook-and-loop fastener piece 10a attached to the frame members 2 and 3 of the screen door frame 1, it can withstand the severe environment described above, and dust can easily enter between the engagement elements through the gaps in the net 14. The second surface fastener 10b is desirably a framed net 13 that is resistant to washing and washing.

  The configuration of the framed net 13 will be described in detail. The framed net 13 can be attached to the four sides of the insect-proof net 14 attached to the flat portions 6a and 7a of the screen door frame 1 as shown in FIG. The second hook-and-loop fastener piece 10b to be fixed to the first hook-and-loop fastener piece 10a fixed to the screen door frame 1 while fixing the rectangular net frame 15 formed by the connection of the flexible synthetic resin plate material 16. Is fixed to the net frame 15 with the adhesive 17 such as a double-sided adhesive tape through the net 14.

  Moreover, the net frame 15 attached to the four circumferences of the net 14 in the net 13 with the frame is excellent in convenience and operability for the attachment / detachment operation of the net 13 with the frame with respect to the screen door frame 1 and is integrated with the net 14. It is necessary to be formed by strong connection of the flexible plate material 16 that can withstand washing and washing in the corners. Therefore, the corner connecting member 18 that joins the both ends of the four-round plate material 16 of the net frame 15 to each other. At the corners of the net frame 15 and overlapping the ends of the plate members 16 to be joined to each other, and the plate member connecting portions 18a orthogonal to each other, and the gripping portions projecting to the inner corner sides of the two plate member connecting portions 18a 18b, and the plate member connecting portions 18a are joined to the end portions of the plate members 16 orthogonal to each other by bonding, welding, or the like.

  In addition, as shown in FIG. 6, both ends of the plate member 16 are connected to the inside of the corner portion where the plate member connecting portion 18a intersects, as can be seen from FIG. By projecting on the net 14 in a state of being separated from the net 14, a finger hooking gap 19 for gripping the net frame 15 is formed between the gripping portion 18 b and the net 14 below the net 14.

  The finger hooking gap 19 formed under the gripping portion 18b of the corner connecting member 18 has a corner angle of the framed net 13 in which the distribution density of the hook-and-loop fastener is intensively high even when the finger is pulled over and the framed net 13 is pulled out. It is difficult to remove the parts at once, however, if the joint strength is lowered overall to facilitate the removal of the hook-and-loop fastener, the possibility of scattering of the framed net 13 due to a strong wind or the like Therefore, in this framed net 13, as shown in FIG. 5, at each corner portion of the framed net 13, an engagement element for joining the first and second hook-and-loop fastener pieces 10 a and 10 b to each other. 11 is formed so as to make a part of 11 a non-functional portion, and a means for adjusting in a direction to weaken the joining force between the corner portion of the screen door frame 1 and the net 13 with frame is adopted. Surface fastener pieces 10a in, while facilitating disengagement of 10b mutual, and configured to suppress a reduction in the bonding strength of the frame with the net 13 against the screen door frame 1.

  The deactivation of the engaging element 11 of the first and second hook-and-loop fastener pieces 10a and 10b at the corners of the screen door frame 1 and the framed net 13 means that part of the engaging piece 11 of the hook-and-loop fastener piece is cut off. Then, when the engaging function is lost by heating some of the engaging elements 11 or when both ends of the plate 16 constituting the net frame 15 are joined by the corner connecting members 18, they are positioned at the corners of the hook-and-loop fastener piece. A means such as pressing the engaging element 11 of the hook-and-loop fastener piece at the corner portion to eliminate the joining force by the eyelet-like or rivet-like member connecting the plate member 16 and the corner connecting member 18 to the portion to be Is used to suppress the joining function of the hook-and-loop fastener pieces 10a and 10b, and the non-functioning of the engaging element 11 is performed for at least one engaging element of the first and second hook-and-loop fasteners. Bayoi. The adjustment of the joining force of the hook-and-loop fastener can be performed depending on how large the engagement member removing portion 10c is formed at the corner portion of the hook-and-loop fastener piece.

  In particular, as described above, a finger-hanging gap 19 is provided below the grip portion 18b of the corner connecting member 18 to facilitate the lifting of the corner of the framed net 13 and at the corner of the framed net 13 at the same time. If the hook 11 part of the hook 11 is made non-functional so that the hooking force of the hook and loop fastener on the corner portion side is further reduced than the gripping portion 18b, the finger hooking gap 19 is removed to remove the framed net 13. When the gripping portion 18b is moved up by the operation of the inserted fingertip, the corner portion side of the framed net 13 is likely to float with respect to the screen door frame 1. Therefore, the framed net 13 is separated from the gripping portion 18b. When the operation is performed so as to lift the tip of the corner, the framed net 13 can be easily detached from the screen door frame 1. Moreover, the first and second hook-and-loop fastener pieces 10a and 10b attached to the net frame 15 in the frame-equipped net 13 cannot be easily detached except for the operation of the gripping portion 18b. It can be held stably.

  As described above in detail, the framed net 13 described with reference to FIG. 4 is attached to the first hook-and-loop fastener 10a attached to the frame members 2 and 3 in the screen door frame 1, and the second attached to it. When the hook-and-loop fastener 10b is attached by joining from the indoor side, a screen door as shown in FIG. 6 can be obtained.

  Further, as shown in FIG. 7, the screen door according to the present invention is an intermediate rail that partitions the inside of the screen door frame 1 vertically in the middle part between the upper and lower horizontal frame members 3 of the screen door frame 1. 21 can also be configured as a bridge constructed between a pair of vertical frame members 2. The intermediate rail 21 corresponds to the flat surface portion 7a for attaching the first hook-and-loop fastener provided on the indoor side of the screen door frame 1 on the side facing the upper and lower partition regions 24 in the screen door frame 1 partitioned thereby. And a fixing protrusion 8 for the first hook-and-loop fastener piece 10a is provided to protrude along both sides of the mounting position of the hook-and-loop fastener piece on the intermediate-piece flat surface portion 23a. In each of the upper and lower partition regions 24 partitioned by the middle rail 21, the framed nets 13 are formed so as to be independently attachable. Except for the configuration of the part related to the middle rail 21 in the screen door provided with the middle rail 21, there is no difference from the embodiment shown in FIGS. 1 to 5, and the framed net 13 has the same size as the above. It can be used according to the partition area 24 partitioned by the crosspiece 21.

  The screen door provided with the intermediate rail 21 facilitates cleaning and replacement by removing the net 14 because the screen door according to the present invention facilitates cleaning and replacement by miniaturizing the framed net 13 itself. The net 14 with good external transparency is stretched over the upper half of the screen door, and the net 14 is difficult to see indoors in the lower half of the screen door. The function of the net depends on the vertical part in the screen door frame 1 such as a net 14 that is used as a blindfold and a high-strength net 14 that is not easily damaged by infants and pet cats. It is also effective to enable selection.
