Description

  TECHNICAL FIELD The present invention relates to an assembly screen door suitable for being installed in a part of a building opening or the like where the screen door is to be installed while being assembled to fit the part, and an assembling method thereof.

  If you want to install a screen door in an existing building opening, etc., it is usually necessary to prepare a screen door with a frame that is assembled in a size that fits the installation site, and then use the mounting angle and other fixtures to install the screen door frame. The means of fixing to the position is adopted. In this case, since a screen door with a frame prepared in advance is used, the installation itself can be performed relatively easily, but it is necessary to transport a pre-assembled large screen door with a frame to the installation location. Yes, and when it is necessary to replace the net, it was originally prepared as a framed screen door, so it is difficult to obtain and replace only the net, so remove the framed screen door again to the manufacturer. You will be forced to do relatively cumbersome and large-scale work such as transporting it for repair or replacing it with a new one. In addition, when fixing the screen door with a frame with a mounting angle or the like, the screen door frame around the mounting angle and the screen door with the frame is disposed on the inner periphery of the opening of the building. The field of view is narrowed and the feeling of opening is impaired.

  Such a problem can be solved by adopting a configuration in which a net can be directly attached to the indoor side of the shoji as shown in Patent Documents 1 and 2 and the like. The sash disclosed in Patent Document 1 is to fix a net provided with bulging protrusions 32 on both side ends by pushing an attachment 31 attached to the bulging protrusion 32 into an attachment groove 41 of the sash. However, only the left and right ends of the net are attached with the attachment, and the upper and lower ends of the net are merely brought into contact with the protrusions of the upper and lower frames. This is because, as is clear from the one described in Patent Document 2, not only the left and right sides of the net but also the upper and lower sides are attached in the same manner because there is a problem in workability.

  The above workability will be described with reference to Patent Document 2. In the screen extending mechanism described in Patent Document 2, the bulging portion 4 attached to the four circumferences of the screen is fixed to the vertical screen attaching portion 1A in the sash. In this case, the groove lid 12 having the bulging portion 4 engaged with the engagement groove 15 is used by the first fixing means for engaging the attachment groove 7. In the horizontal screen attachment portion 1 B, the attachment groove 8 is formed. Second fixing means for locking the bulging portion 4 between the lip 8a and the groove cover 22 applied to the mounting groove 8 to lock the groove cover 22 to the lip 8a of the mounting groove 8. Is used.

  For example, if the first fixing means is used in both the vertical and horizontal screen mounting portions, for example, the groove cover in which the bulging portion 4 is locked to the engaging groove 15 with respect to the pair of vertical screen mounting portions 1A. 12 is engaged to complete the installation of the screen to the vertical screen mounting portion, and the groove cover 12 at the end of the screen to be attached to the horizontal screen mounting portion 1B is attached to the vertical screen mounting portion 1A. This is because it interferes with the groove cover 12 and must be avoided. That is, at the stage where the screen is attached to the vertical screen attachment portion 1A, the bulging portion 4 at the end of the screen to be attached to the horizontal screen attachment portion 1B is located in the attachment groove of the screen attachment portion 1B. Therefore, the groove lid 12 cannot be attached to the end of the screen in advance, and the groove lid 12 can be attached at this time unless the groove lid 12 is attached in advance to the end of the screen. This is because a difficult operation such as attaching the groove cover 12 to the vertical and horizontal screen attaching portions 1A and 1B at a stroke is required.

  On the other hand, when the fixing means of the bulging portion 4 is different in the vertical and horizontal screen mounting portions as in Patent Document 2, the groove lid 12 of the first fixing means is previously placed in the engagement groove 15 of the screen 3. It is suitable for engaging the groove lid 12 with the mounting groove 7 after the bulging portion 4 has been inserted, whereas the second fixing means is provided on the edge 8a of the mounting groove 8 in the groove material 6. Since the groove cover 22 is closed while the screen bulging portion 4 is held, the bulging portion 4 of the screen 3 can be fixed as an operation at another stage, so that the screen mounting operation is simplified. However, it is necessary to use the first and second fixing means, and the configuration cannot always be simplified.

  The technical problem of the present invention is that the screen door that can be installed while assembling to fit the part where the screen door in the building opening or the like is to be installed, while using the same member for the four circumferences of the net, the installation of the net, An object of the present invention is to provide an assembling screen door and an assembling method thereof that can easily remove a net for maintenance or the like.

To solve the above problems, the present invention, along the edge of the four sides of the net member, a net attach the tape having a plurality of protruding pieces for engagement, each of the four sides of the net The slit is provided along the longitudinal direction for holding the bulging part piece of the side by engagement inside the slit, and an engagement protrusion having an elastic expansion tendency is provided along the longitudinal direction. comprising, a rail in which the engagement projection when pushed into the mounting groove of the outer rails are formed so as to engage the outer rail disposed at a site to be installed a mesh door, the four sides of the net The middle rail in which at least one of the parts to be attached is divided in the middle, and a locking portion to which the engaging ridge is locked when the middle rail is pushed into the mounting groove are in the mounting groove. And the outer rail provided. Assembly screen door is provided.

  In a preferred embodiment of the assembly screen door according to the present invention, the middle rails attached to the pair of opposite sides of the net are configured to be divided into two parts, respectively, One or both of the locking portions of the outer rail locked by the engaging ridges are arranged in parallel, and the locking position by pressing the middle rail into the mounting groove can be adjusted. It is desirable to do.

  Furthermore, in a preferred embodiment of the present invention, when the intermediate rail is removed, the outer rail is protruded against a part of the locking portion of the outer rail against the elastic expansion tendency. A tool insertion notch required to disengage from the rail locking part is provided, and the middle rail mounting groove on the outer rail pushes the middle rail perpendicular to the net tension The outer rail may be formed on a part of the sash frame installed in the building opening.

In order to solve the above problems, according to the present invention, along the edge of the four sides of the net member, and the net fitted with a tape having a plurality of protruding pieces for engagement, each of the four sides of the net The slit is provided along the longitudinal direction for holding the bulging part piece of the side by engagement inside the slit, and an engagement protrusion having an elastic expansion tendency is provided along the longitudinal direction. comprising a rail in which the engagement projection when pushed into the mounting groove of the outer rails are formed so as to engage the outer rail disposed at a site to be installed a mesh door, mounting groove the in rail A method for assembling an assembly screen door having the outer rail provided in the mounting groove with a locking portion that locks the engaging protrusion when it is pushed into the mounting groove. Of the middle rails to be When assembling, first, the middle rails that are not divided and attached to the bulging pieces around the net are pushed into the mounting grooves of the outer rails to be divided. Before the middle rail that is located on both sides of the bulging piece on the periphery of the net to which the middle rail is to be attached is pushed into the mounting groove of the outer rail, the divided middle rail is attached, The end of each adjacent side of the divided middle rail is pushed into the mounting groove of the outer rail together with the middle rail located on both ends thereof, and then the middle side of the divided middle rail is moved to the outer rail. A method of assembling an assembly screen door is provided, wherein the assembly screen door is pressed and locked.

  In order to install the assembly screen door having the above-described configuration, for example, first, a large number of bulging pieces for engagement provided at each end of two opposite sides or three adjacent sides in the four circumferences of the net, The middle rails are held by the inner rails by engaging the slits inside the slits, and the middle rails are pushed into and locked in the mounting grooves of the opposite or adjacent outer rails, or are held close to each other. At this stage of operation, the middle rails to be pushed and locked do not interfere with each other, and the middle rails can be easily pushed into the outer rail mounting grooves. In addition, since the engagement protrusion of the middle rail has an elastic expansion tendency, the above-mentioned pushing operation is not hindered.

  In this state, it is difficult to attach a middle rail similar to that used previously to the remaining two or one side of the net because adjacent middle rails interfere with each other. Prior to pushing and locking the middle rails of the two or three sides to the outer rails, the middle rails are also attached to the remaining sides in advance, but in order to avoid interference between adjacent middle rails, this The middle rail attached to the bulging piece of the net at the stage is the same cross-sectional shape as the middle rail described above divided in advance in the middle, and if there is still some interference between the middle rails, The middle rail divided into the minimum necessary will be further shortened.

  In this way, when the bulging piece at the end of the net to be attached is engaged with the inside of the slit of the divided middle rail and is held by the divided middle rail, As will be described later with reference to FIGS. 6 to 8, the push-in locking with respect to the outer rails pushes the divided middle rails obliquely with respect to the mounting grooves from their both end portions, thereby Can be held on the outer rail.

At this stage, the middle rail is pushed deeply into the outer rail using a tool or the like, and the middle rail engaging projection and the outer rail are locked together so that the net is properly stretched. By selecting a part, the net can be tensioned.
Note that, here, an example in which the middle rail of the four circumferences of the net is pressed and locked to the outer rail is described, and the pressing and locking is not limited to the above procedure.
When removing the net stretched in the outer rail, a tool is inserted into a notch for inserting a tool provided in a part of the locking portion of the outer rail, and the engagement protrusion of the middle rail is elastically moved. The middle rail may be sequentially detached from the outer rail in a process substantially opposite to the above-described net tensioning process, while being separated from the locking portion of the outer rail against a general expansion tendency.

  According to the assembly screen door and the assembly method of the present invention described in detail above, the screen door that can be installed while being assembled to fit the part where the screen door in the building opening or the like is to be installed is the same member for the four circumferences of the net. While simplifying the configuration, it is possible to easily remove the net for maintenance as well as to install it.

  1-10 has shown an example of implementation of the assembly screen door which concerns on this invention. This assembled screen door is suitable for assembly and installation so as to fit the part where the screen door is to be installed inside the window sash at the opening of the building, so it is also suitable as a retrofit screen door, and the net 1 is installed on the screen door It can be stretched according to the size of the part. In addition, when the net 1 is soiled or damaged due to long-term use or the like, this assembly screen door can easily perform maintenance and replacement such as cleaning of the net 1.

  As shown in FIG. 1, the net 1 used in this assembly screen has a tape 3 having a large number of bulging pieces 3 a for engagement along end portions of the circumference of the net material 2. As the tape 3 to which the bulging piece 3a is attached, it is desirable to use a half of a fastener used for joining ends of a cloth or the like. For the attachment of the tape 3 to the end of the net member 2, various means such as welding, adhesion, and sewing can be used. When the net 1 is stretched at a site where a screen door such as a building opening is desired to be installed, the tape 3 is attached to the net material 2 using a net material 2 cut by the installation operator so as to conform to the dimensions of the site. 2 is attached by the above-mentioned various means. For this reason, the manufacturer / seller of an assembly screen door is set to a standard size generally used and attached to the net material 2 with the tape 3 or dimensional If the installation material is provided with the net material 2 having a sufficient margin and the tape 3 that can be attached thereto, the operator can cope with various dimensions.

As will be described in detail below, the net 1 is attached to the outer rail 11 via the middle rail 5 and the short middle rail 5a in which each side of the four circumferences is divided in the middle.
The middle rails 5 and 5a are made of elastic synthetic resin and are formed as long deep groove-like members that sandwich the end of the net 1 together with the tape 3 with a constant cross-sectional shape, and are clearly shown in FIGS. As described above, the slit 6 along the longitudinal direction of the member and the holding groove 7 for holding the bulged part piece 3a by the engagement of the bulged part piece 3a inside the slit 6 are provided. , One of the pair of opposing walls 8 and 9 extending to the mouth side from them, that is, the opposing wall 8 that is positioned on the surface side of the outer rail 11 when the middle rails 5 and 5a are pressed and locked to the outer rail 11, There are provided two engaging ridges 10 along the longitudinal direction which have an elastic expansion tendency due to the elasticity of the opposing wall 8.

  The outer rail 11 disposed at the part where the screen door is to be installed in the opening of the building includes a mounting groove 12 into which the middle rail 5 is pushed in from the holding groove 7 side. When the rail 5 is pushed into the mounting groove 12, an engaging portion 13 is provided to which the engaging protrusion 10 of the intermediate rail 5 is engaged. As shown in FIGS. 4 and 5, etc., the outer rail 11 in the illustrated embodiment is configured so that it can be fixed at an arbitrary position of the building opening with the mounting screw 14, but is installed in the building opening. The outer rail 11 having the mounting groove 12 may be formed on a part of the sash frame as an integral part of the sash frame.

  Further, in the illustrated embodiment, the middle rail 5 is provided with two engaging ridges 10, and the outer rail 11 is provided with one locking portion 13 for locking the engaging ridges 10, As shown in FIG. 4 or 5, an appropriate tension is applied to the net 1 depending on whether one of the two engaging protrusions 10 is locked to the locking portion 13 of the outer rail 11. However, the present invention is not limited thereto, and one or both of the engaging ridges 10 and the locking portions 13 are arranged in parallel, and their engagement by pushing the middle rail 5 into the mounting groove 12 of the outer rail 11. The stop position can be adjusted in multiple stages.

  Further, when it is necessary to remove the middle rail 5 for exchanging the net 1 or the like in a state where the engaging protrusion 10 of the middle rail 5 is locked to the locking portion 13 of the outer rail 11, FIG. As shown in FIG. 9, when the engaging protrusion 10 on the opening end side of the opposing wall 8 of the middle rail 5 is outside the locking portion 13 of the outer rail 11, a tool 16 such as a screwdriver is used as shown in FIG. 9. As a result, the engaging ridge 10 of the intermediate rail 5 is pushed up against the elastic expanding tendency of the opposing wall 8 and the engaging ridge 10 is released from the engaging portion 13 of the outer rail 11. The intermediate rail 5 can be removed from the outer rail 11 by this.

  However, as shown in FIG. 5, when the locking portion 13 of the outer rail 11 is outside the engaging protrusion 10 provided on the opposing wall 8 of the middle rail 5, this is the removal of the middle rail 5 described above. As shown in FIG. 10, when the middle rail 5 is removed from a part of the locking portion 13 of the outer rail 11, it is easy to push up the engaging protrusion 10 of the middle rail 5. A notch 13a for tool insertion is provided. Therefore, as shown in the figure, the tool 16 is pushed under the engaging protrusion 10 of the opposing wall 8 through the notch 13a, and the engaging protrusion is resisted against the elastic expansion tendency of the opposing wall 8. The middle rail 5 can be easily detached by pushing 10 up from the locking portion 13 of the outer rail 11.

  As can be seen from FIGS. 6 to 8, the middle rail has at least one of the middle rails attached to the bulging piece 3 a on the four circumferences of the net 1 as a short middle rail 5 a divided in the middle. Yes. As shown in FIGS. 6 and 7, in the case where the middle rail 5a is divided into two each of the middle rails attached to the pair of opposite sides of the net 1, the net is relatively relatively small as will be described in detail below. However, even if only a single middle rail is divided as shown in FIG. 8, the net 1 can be stretched while avoiding interference between adjacent middle rails 5 and 5a. . Note that three or more middle rails 5 may be divided at the center.

Next, an example of an assembly method for the assembly screen door described above will be described.
First, when the net 1 to be stretched is prepared as a net material 2 having a required size and a tape 3 having a bulging portion 3a attached thereto, it is used and prepared. If there is not, the tape 3 having the bulging piece 3a is attached to the ends of the four circumferences of the net material 2 cut to a required size by means of welding, bonding, sewing, etc., and the screen door is installed. The net 1 adapted to the size of the part to be obtained is obtained.

  The assembly screen door can be assembled according to the procedure shown in FIGS. 6 and 7. In this case, first, a large number of engagement screens provided at the ends of the two opposite sides of the net 1 are arranged. The bulging part pieces 3a are respectively held by the inner rails 5 by engaging the inner rails 5 with the slits 6 inside, and the middle rails 5 are pressed and locked in the mounting grooves 12 of the outer rails 11 facing each other. Before the push-in locking, the opposite two sides of the bulging portion 3a remaining in the four circumferences of the net 1 are held in advance by two short middle rails 5a. It should be noted that the short middle rail 5a may be attached at that time as long as it can be attached to the bulging portion pieces 3a on the two opposite sides where the net 1 remains at the further progress of assembly.

  Then, as shown in FIG. 6, the holding groove 7 side of the pair of middle rails 5 that are not divided are sequentially brought into the mounting groove 12 of the outer rail 11, and at that time, the short middle rail 5 a A state in which the end adjacent to the middle rail 5 is pushed into the outer rail 11 in a direction facing the facing walls 8 and 9 of the pair of middle rails 5 facing the outer rail 11. In this state, the short middle rail 5a is also inserted into each of both sides while widening the gap between the pair of middle rails 5 facing the mounting groove 12 of the outer rail 11 and pushing into the opposite outer rails 11. Rotating around the end close to the rail 5 and pushing it into the outer rail 11, the middle rail 5 a is pushed into and locked to the outer rail 11 through the state of FIG. 6 to the state of FIG. 7.

  At this time, the net 1 is not always in a tensioned state. Therefore, finally, as shown in FIG. 7, the middle rail 5a is pushed in using the tool 16 so that the net 1 is in a tensioned state. By locking any of the plurality of engaging protrusions 10 and the locking portion 13, the locking position is adjusted, and the net 1 is stretched in a necessary tension state.

  At the stage of these operations, the adjacent two middle rails 5 and 5a do not interfere with each other, and the middle rails are easily pushed into the mounting grooves 12 of the outer rail 11 so that the middle rails 5 and 5a The engaging protrusion 10 can be locked to the locking portion 13 of the outer rail 11. In addition, since the middle rail engaging protrusion 10 has an elastic expansion tendency, the middle rail can be easily pushed into the outer rail 11. If it is unavoidable that the adjacent middle rails 5 and 5a interfere with each other, the middle rail can be shortened to the minimum necessary. It won't interfere with the net installation.

  6 and 7 show a case where the short middle rail 5a divided in the middle is used on the two opposite sides of the net 1, the middle rail 5a is pushed into the mounting groove 12 and locked. Of the middle rails, only the one that is pushed into and locked to the outer rail 11 at the end can be used. That is, as shown in FIG. 8, the middle rail 5 that is not divided is attached to the three bulging pieces 3a around the net 1, and the middle rail 5a that is divided into the remaining one side is attached and divided. The middle one of the three middle rails 5 is pushed into the mounting groove 12 of the outer rail 11, and the middle rail 5 having end portions adjacent to both ends thereof is inclined as shown in FIG. The end portion is pushed into the mounting groove 12 of the outer rail 11, and then the end portions on the adjacent sides of the divided middle rail 5a are mounted together with the middle rail 5 located on both end sides of the outer rail 11. The screen door can be stretched by pressing and locking the groove 12 and then pressing and locking the center side of the divided middle rail 5a to the outer rail 11.

It should be noted that adjusting the locking positions of the plurality of engaging protrusions 10 and the locking portions 13 by pushing the middle rails 5 and 5a so that the net 1 is in a tension state is related to FIG. This is the same as described above.
In the examples of FIGS. 6 to 8, the widths of the middle rails 5 and 5 a and the outer rail 11 are particularly enlarged with respect to the other portions, so that the middle rails 5 and 5 a are shortened. However, in an actual product, there is no particularly large gap between the divided middle rails 5a.

  In the above embodiment, the mounting grooves 12 of the middle rails 5 and 5a in the outer rail 11 are formed so as to push in the direction in which the middle rail is expanded toward the outside of the four circumferences in the stretched surface of the net 1. As shown in FIGS. 11 and 12, the outer rail 11 may be formed so as to push the middle rails 5 and 5a at a right angle with respect to the stretched surface of the net 1. The opening area of the building opening to which the net 1 is attached can be made as large as possible.

In the case of this embodiment, if the middle rails on the four circumferences of the net 1 are pressed and locked to the outer rails 11 at a time, each middle rail is not necessarily divided in the middle, and each middle rail is not necessarily divided in the middle. 11 can be pushed into the outer rail, but it becomes easy to push the middle rails into the outer rails sequentially by dividing the middle rails.
11 and 12 are the same as or equivalent to those shown in the drawings because the configurations and operations other than those described above are not substantially different from those of the embodiments shown in FIGS. The description of them will be omitted.
