Description

  The present invention relates to a screen door that is attached to a building opening so that it can be easily attached and detached from the indoor side for cleaning and replacement, and more specifically, the screen door net. This relates to the mounting structure.

  In recent years, screen doors installed in middle- and high-rise apartments, etc. are fixed to the building opening frame to prevent the screen doors from falling and maintenance is easy, and the nets are used as screen door frames for cleaning and replacement. On the other hand, it is required to be easily attachable / detachable from the indoor side, and various types have been proposed in which this can be easily performed. In addition, such screen doors are used not only for middle- and high-rise apartment buildings, but also for nets that are fixed to the outdoor side of screen door frames used in general houses, etc. from the indoor side of the screen door frame. It is desired that the net can be attached / detached and replaced with a simple operation.

  Such a screen door is installed in a building opening frame or the like, and the net is easily detachable from the indoor side to a square screen door frame for cleaning or replacement. As disclosed in a number of documents including, a net frame that can be attached to and detached from the screen door frame with a hook-and-loop fastener from the indoor side, and a net frame that is attached around the net for reinforcement. , Using a plate material made of synthetic resin that can be bent elastically to some extent, and a belt-like material having excellent flexibility such as a cloth made of chemical fiber, etc., and fixing them to the periphery of the net, The thing which made the handling of a net with a frame convenient by fixing the above-mentioned hook-and-loop fastener etc. is proposed.

  As mentioned above, the net that can be attached to and detached from the screen door frame with a hook-and-loop fastener from the indoor side is convenient for handling when attaching the net with a frame to the screen door frame, and when replacing the net. Excellent safety. However, considering the ease of removing the framed net from the screen door frame for exchanging the net, etc., if the framed net is made very easy to remove, It may come into contact with a part or clothing and disengage from it, or it may easily come off and become dangerous due to the mischief of infants or pets. Although it is a mode in which the framed net does not come off unexpectedly in an unforeseen situation, it should be considered that it can be removed relatively easily by workers who are cleaning or replacing the net, and the It is desirable that the mounting be relatively easy and accurate at the intended position, and that the net can be fixed in a tensioned state.

Japanese Utility Model Publication No. 62-101998 JP 2009-235705 A

  In view of the above-described background art, the technical problem of the present invention is that for a person who performs a work of cleaning or replacing a framed net in a screen door in which a net with a frame is attached to and detached from the indoor door frame of a building opening with a hook-and-loop fastener. Will not interfere with attachment / detachment, but it will not be easily disengaged by contact with a part of the body or clothing moving near the screen door, and it is also possible to attach a framed net as much as possible. It is another object of the present invention to provide a framed net mounting structure that makes it possible to neatly stretch the net.

  In order to solve the above-described problems, according to the present invention, a frame material is framed in a square shape, and includes a metal screen door frame that is installed on the outdoor side of the shoji at the opening of the building. A flat surface portion for attaching a hook-and-loop fastener is formed on the inner peripheral side of the material from a portion close to the outdoor surface side of the screen door frame toward the inside of the frame, and the first hook-and-loop fastener is one of a pair of hook-and-loop fasteners on the flat surface portion On the other hand, the net with a frame fixed to the flat portion of the screen door frame through the first hook-and-loop fastener piece is densely planted on a flexible base fabric made of chemical fiber. Tape-shaped second hook-and-loop fastener pieces that engage with the hooks of the first hook-and-loop fastener pieces are arranged on the four sides of the net for the screen door, and are provided along the inside of the base cloth. The connection margin is joined to the periphery of the net, and the second at the four corners of the net. A synthetic resin plate-shaped corner piece covering them is attached to the overlapping portion of the base fabric end of the hook-and-loop fastener piece, and the surface of the corner piece is an intersection of the frame material around the four door frames. The framed net with the corner piece attached to the portion of the indoor side surface that has been depressed by a large step from the indoor side surface, the corner piece at the corner is at the intersection of the four-frame frame material in the screen door frame The opposite corners are cut diagonally and thinned so that the cut edges can be hooked by the toes, and the gap between the frame members at the intersections cannot be inserted. Thus, on the inner surface side of the corner piece, a screen door is provided in which the engagement of the hook fastener engaging member in a portion near the crossing portion of the frame material of the screen frame is rendered non-functional.

  In the screen door having the above configuration, the corner piece attached to the corner of the net with the frame can be hooked only on the cut edge of the corner facing the intersection of the four-round frame material in the screen door frame. In addition, on the inner surface side of the corner piece, the joining by the engaging element is made non-functional by cutting or melting the engaging element of the hook-and-loop fastener in the portion near the intersection of the frame material of the screen door frame. The corner piece itself can be easily erected to raise the framed net. However, since the surface of the corner piece is located at a site where the surface of the screen door is lowered with a large step from the indoor side surface of the screen door frame, it is not equipped with a structure that can be caught by other objects, so that the net with the frame is unnecessarily unexpected. There is no such thing as leaving.

  In addition, when attaching the framed net to the screen door frame, as can be seen from the above, since the corner piece is attached to both ends of the second hook-and-loop piece constituting each side of the net frame, The net can be neatly stretched in a tensioned state by pulling the pair of corner pieces left and right and attaching them to the first hook-and-loop fastener piece attached to the screen door frame.

  In a preferred embodiment of the screen door according to the present invention, the first hook-and-loop fastener piece is fixed to the flat portion of the frame member in the screen door frame along both sides of the mounting position of the first hook-and-loop piece in the flat portion. This is done by pinching the side ends of the hook-and-loop fastener piece by bending the fixing protrusion protruding inward. Such a configuration is particularly effective for stabilizing the fastening of the hook-and-loop fastener to the screen door frame placed in a harsh natural environment in the long term.

  Further, in another preferred embodiment of the screen door according to the present invention, the framed net is formed of a flexible base fabric in a second hook-and-loop piece made of nylon on the four circumferences of the net coated with glass fiber on PVC. The second hook-and-loop fastener piece is joined to the periphery of the net by sandwiching it between the coupling allowance and a reinforcing sheet made of nylon coated with PVC, and then welding them together. In the above-mentioned second hook-and-loop fastener piece, a laminated nylon plate-like corner piece covering the base cloth end is welded. Such a configuration is effective for obtaining stable and strong joining of the members.

  As described above, the net frame in the framed net is configured by the tape-shaped second hook-and-loop piece in which the engagement element is implanted in the flexible base cloth, and is arranged on the four sides of the net for the screen door. Then, when the connecting margin on the inner side of the base fabric is joined to the periphery of the net, the net with the frame is configured to have a soft flexibility as a whole. It can be very suitable for cleaning. In addition, the storage and shipping of products at screen door manufacturers and distributors have a frame compared to the case of products that are formed as large in area as screen door frames and cannot be folded down and downsized. Obviously, it is very efficient and cost-effective to roll and fold the net to store and transport it.

  However, conversely, when a net for a screen door having a relatively large area and flexibility is attached to the screen door frame, even if a hook-and-loop fastener is attached around the net, When attaching the second hook-and-loop piece on one side of the net to the screen door frame, it is somewhat difficult to attach the net as tightly as possible and without linear displacement. If the first side is not properly attached, each subsequent side is attached sequentially with reference to the attachment position of the first one, so that the whole is disturbed.

  In order to cope with such a problem, in another preferred embodiment of the screen door according to the present invention, in the framed net, the second hook-and-loop piece on one side or two opposite sides of the four-round net frame is a core. Then, the second hook-and-loop fastener piece on one side or the opposite two sides of the net frame is reinforced with a synthetic resin reinforcing material so that the winding shaft is not curved when the net for the screen door is rolled. As a thing, handling can also be comprised conveniently.

  That is, when the second hook-and-loop fastener piece is reinforced by the synthetic resin reinforcing material as necessary, the net for doors is rounded around the reinforced second hook-and-loop piece, and the winding is performed. The shaft can be held so as not to bend. In addition, when attaching the framed net to the screen door frame, if the attachment from the second hook-and-loop fastener piece on the side where the reinforcement is performed to the screen door frame is started, the second hook-and-loop piece puts the net in a tensioned state. Therefore, the second hook-and-loop fastener piece can be fixed relatively easily in the desired position with the net being tensioned, and after the first second hook-and-loop piece is fixed, Since each other side can be attached on the basis of the attachment position, the net can be stretched neatly as a whole. The second hook-and-loop fastener piece of the net frame may be reinforced only by the second hook-and-loop piece on one side of the net frame, but the second hook-and-loop piece on the two opposite sides of the net frame is targeted. May be.

  According to the screen door of the present invention described in detail above, for a screen door in which a net with a frame is attached to and detached from the indoor door frame of a building opening with a hook-and-loop fastener from the indoor side, for those who perform cleaning and replacement work of the net with the frame Although it does not interfere with attachment / detachment, it will not come out of contact with a part of the human body or clothes moving near the screen door, and it will not be easily disengaged. It is possible to obtain a framed net mounting structure that allows the net to be neatly stretched.

It can also be installed in a frame, and in that case, the flat surface portions 6a and 7a for attaching the hook-and-loop fastener are provided inside the screen door frame surrounded by the portions corresponding to the main body portions 4 and 5 in the existing screen door frame. If there are no extension portions 6 and 7 for attaching the net, the one corresponding to the extension portions 6 and 7 may be firmly attached to the existing main body portion.

  In the corner part which connects the both ends of the said vertical and horizontal frame materials 2 and 3, a main-body part by excising each part of the main-body part 4 and the extension part 6 in the up-and-down both ends of the vertical frame material 2 4, the end 3 a of the horizontal frame member 3 is inserted into the insertion groove 2 a formed in the inner wall 4, and the inner wall of the vertical frame member 2 is inserted into the screw pocket 3 b formed in the horizontal frame member 3. The screen door frame 1 is squarely formed by connecting the vertical and horizontal frame members 2 and 3 at each corner by means such as screwing screws through screw holes provided in 2b.

  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 provided with insect-proof nets 14 as shown in FIGS. As shown in FIGS. 1 and 2, both sides of the mounting position for attaching the first hook-and-loop fastener piece 10a, which is one of a pair of hook-and-loop fasteners, are provided. The fixing protrusions 8 for fixing the hook-and-loop fastener piece 10a are bent inward from each other and protruded from each other. The fixing of the first hook-and-loop fastener piece 10a by the fixing protrusion 8 is performed in a state where the first hook-and-loop fastener piece 10a is disposed on the flat surface portions 6a and 7a between the pair of fixing protrusions 8. It is performed by bending the tip end of the fixing protrusion 8 inward with a tool such as a pressure roller, and sandwiching both side edges of the first hook-and-loop fastener piece 10a between the flat portions 6a and 7a. It is.

  The mounting structure itself including the fixing protrusion 8 for mounting the first hook-and-loop fastener 10a to the flat surface portion 6a provided on the extending portion 6 of the vertical frame member 2 is shown in FIGS. Therefore, detailed illustration and description thereof are omitted.

The first hook-and-loop fastener piece 10a attached to the vertical and horizontal frame members 2 and 3 is a first hook-and-loop net 13 as shown in FIGS. 2, 3 and 5 that forms a pair with the first hook-and-loop fastener piece 10a. It is for attaching with the 2 hook-and-loop fastener piece 10b.
In addition, although the said hook_and_loop | surface fastener is generally comprised as what closely engaged the engaging elements 11a and 11b of many hook shape and pile shape which can be engaged by mutual joining. Any one of the first and second hook-and-loop fastener pieces 10a and 10b may be selected. However, for example, the first hook-and-loop fastener piece 10a to be attached to the frame members 2 and 3 of the screen door frame 1 is preferably a pile-shaped engagement element that is easy to touch. Is placed in an inferior outdoor environment, it is also desirable that it can withstand that environment.

Next, about the structure of the said net 13 with a frame detachably attached to this screen door frame 1 via the 1st hook-and-loop piece 10a attached to the frame materials 2 and 3 of the said screen door frame 1, FIGS. This will be specifically described with reference to FIG.
As shown in FIGS. 3 and 5, the frame-equipped net 13 has a tape-shaped second hook-and-loop fastener piece 10 b that engages with the engaging element 11 a of the first hook-and-loop fastener piece 10 a as a net for a screen door. A net frame 15 that reinforces the periphery of the net 14 is formed by joining the four circumferences of the net 14. The second hook-and-loop fastener piece 10b is configured by densely implanting the engaging element 11b on a flexible base cloth 12 made of chemical fiber such as nylon.

  Specifically, the joining of the second hook-and-loop fastener piece 10b and the net 14 is performed on the coupling allowance 12a provided along the net 14 side on the base fabric 12 in the second hook-and-loop fastener piece. The periphery of the net 14 is placed, and the periphery of the net 14 is sandwiched between the reinforcing sheet 16 placed on the net 14 and welded as a whole. A rectangular net frame 15 is formed around the net 14 by joining the second hook-and-loop fastener pieces 10b to 12a and sequentially connecting the end portions of the second hook-and-loop fastener pieces.

  Specifically, it is desirable that the material of the net 14 is a glass fiber coated with PVC, the second hook-and-loop fastener piece 10b is made of nylon, and further, the base in the second hook-and-loop fastener piece 10b is used. In order to join the connection margin 12a provided on the net 14 side of the cloth 12 (nylon) to the periphery of the net 14, even if the net 14 is PVC coated on the glass fiber, the stable welding is not possible. Because of the difficulty, it is desirable to place a reinforcing sheet 16 made of a PVC-coated nylon sheet as a connecting material, and to integrally weld the laminate.
