Description

  The present invention relates to a screen structure, and more particularly, to an improvement in a screen structure that is provided at an opening in a house or the like to prevent insects from entering the outdoors.

  Traditionally, openings in houses and the like have been provided with a shoji screen for the purpose of shielding, but openings that do not allow people to enter and exit are generally provided with a shoji window that guarantees viewability and daylighting. A screen door is provided for the purpose of preventing insects when ensuring air permeability.

  And as a screen door, since the opening-and-closing operation | movement in a window differs variously, the thing of the various aspect has been proposed until now.

  In Patent Document 1, a folding type screen door is proposed, and according to this screen door, the screen door expands and contracts in the lateral direction and opens and closes, so that insect protection can be achieved when the screen door is extended while it is not used. By folding, it is possible to prevent the view and lighting of the window from being disturbed.

Japanese Patent No. 2564242

  When the screen door is provided so as to cover the window outside or on the inside of the window, there is a problem that the screen door when not in use hinders the viewability and the daylighting of the window.

  On the other hand, in the proposal disclosed in Patent Document 1, the screen door is formed in a folding type and can be folded when not in use, so that it is possible not to disturb the viewability and daylighting of the window. Become.

  However, since it is necessary to open the window and extend the screen when using it, it is impossible to prevent insects from the outside from entering the room when the window is opened.

  Also, when the screen door is on the indoor side and the window is on the outdoor side, in order to ensure air permeability, the window is opened after opening the screen door, so to speak, when both are opened, Insects from outside cannot enter the room.

  In other words, with the conventional screen door structure, insects from outside enter the room when the window is opened in order to ensure the air permeability of the screen door, even if the screen door does not interfere with the viewability and daylighting of the window. There was a possibility that could not be prevented.

  The present invention was created in view of the above-described present situation, and the purpose of the invention is to ensure that the screen door does not interfere with the view and lighting of the window, and that the screen door is opened to ensure air permeability. It is intended to provide a screen door structure that can prevent insects from the outside from entering the room.

  In order to achieve the above-described object, the screen door structure according to the present invention has a structure of a window frame that forms an opening, a window that is provided on the window frame so as to be openable and opens and closes the opening, and an indoor insect insect. In a screen structure having a screen door that prevents entry into the screen, the screen door is formed so as to be stretchable and provided at one end of the screen to enable connection to the window frame side. Suppose that it has the window frame side connection means to perform, and the window side connection means which is provided in the other end part of the above-mentioned insect net and enables connection to the above-mentioned window side.

  Therefore, in this invention, since one end portion of the insect screen in the screen door has the window frame side connecting means and the other end portion has the window side connecting means, the insect net is connected to the window frame side by the connecting means on each side. It can be connected to the window side, and the screen door can be provided in a state where the window is not covered.

  In the present invention, the screen door connected to the window frame and the window by the connecting means on each side is formed such that the insect screen is stretchable, so that part or all of the window is opened away from the window frame. When the window is opened, it spreads following the movement of the window, and a part or all of the vacant space appearing between the window frame and the window is blocked.

  In other words, in the present invention, when the window that shields the opening is opened to ensure the air permeability by the screen door, the screen door spreads following the movement of the window, so that the window and the window can be opened without opening and closing the screen door. A screen door can be provided between the frame and the situation where both the window and the screen door can be opened at the same time.

  As a result, according to the present invention, the screen door does not disturb the viewability and daylighting of the window, and when opening the window to ensure air permeability through the screen door, insects from the outdoors are prevented from entering the indoor it can.

It is a partial expanded cross-sectional view which shows other embodiment of the connection state to the window frame of a screen door, and a window.

  Hereinafter, the present invention will be described based on the illustrated embodiment. As shown in FIG. 1A, the present invention is directed to an opening (not shown) portion formed in a wall H1 in a house H having a window W as a obstacle. Suitable for the realization of an opening (not shown) formed in the roof H2 in the house H having the skylight W1 as a shoji. Further, as shown in FIG. It is suitable for implementation in an opening (not shown) formed in the roof C1 of the vehicle C having the skylight W2.

  Therefore, in the following description, the case where the present invention is embodied in the opening portion formed in the wall H1 in the house H having the obstacle window W will be described as an example.

  As shown in FIG. 2, the screen door structure according to the present invention has a window frame 1, a window W (frame 2 and glass 3), and a screen door 4. When the window W is opened to ensure air permeability, The screen door 4 is configured to prevent insects from entering the indoor I from the outdoor O.

  The window frame 1 is a base frame that forms an opening in a house H (see FIG. 1A) that does not allow people to enter and exit, and the opening forms a wall H1 of the house H (see FIG. 1A) and the like. It is provided in the housing B, and allows communication between the outdoor O and the indoor I, and allows lighting and ventilation.

  By the way, the structure of the frame B differs depending on the construction material such as a house, and it is arbitrary depending on the wood type or the concrete type, but the difference in the configuration of the frame B does not prevent the establishment of the present invention. Of course.

  Further, the window frame 1 finishes the inner periphery of the opening formed in the casing B and enables connection and holding of the window W described later. In the illustrated embodiment, the window frame 1 is formed so that the front shape is a frame shape. Being done.

  That is, in general, the window W is formed to have a rectangular front shape. Therefore, in many cases, the front shape of the window frame 1 that connects and holds the window W is the front shape of the window W. To be similar, it is formed in a quadrangular shape, that is, a frame shape.

  By the way, in the realization of the present invention, the window frame 1 has a circular front shape or other arbitrary shape so as to be similar to the front shape of the window W or not. Of course, it does not prevent it.

  In addition, the constituent material of the window frame 1 may be arbitrary. However, in the case where a later-described frame 2 constituting the window W is made of an aluminum extrusion mold material or a synthetic resin material, the connection with the frame 2 and the like In consideration of the connection and in consideration of the realization of the present invention, it is preferable to be made of an aluminum extrusion mold material or a synthetic resin material that makes it easy to finish the finding surface 1a and the inner peripheral surface 1b flat.

  In addition, when the window frame 1 is formed in a frame shape, although not shown in detail, the upper side portion, the lower side portion 11, and a pair of left and right sides, the upper and lower ends are respectively an upper side portion and a lower side portion. 11 and a pair of vertical portions 12 and 13 connected to each other.

  Although not shown, the window frame 1 has a door stop that allows the window W to come into contact with the door end side of the frame 2, and has a seal for the purpose of cushioning and waterproofing with the frame 2. Is preferred.

  Then, the above-described seal for shock mitigation and waterproofing may be provided on the frame 2 in the window W which is the outer side of the screen door 4 to be described later, as indicated by reference numeral S in FIG. However, it is good also as being provided in the finding surface 1a of the window frame 1 so that it may be positioned inside the screen door 4. FIG.

  The window W is a shoji that shields the opening while ensuring the viewability and the daylighting. As long as the window W is a shoji, the opening does not have to be openable / closable. The outdoor O and the indoor I which are provided so as to be openable and can communicate with each other through the opening can be shielded.

  And this window W consists of the assembly of the frame 2 and the glass 3 in illustration, and as shown by the dashed-dotted arrow a in FIG. 2, the frame 2 becomes what is called a suspension base which becomes the right side in FIG. The so-called door end side, which is the left side in FIG. 2, is turned to the outdoor O side with the side pivoted (see FIG. 5), and is formed in an outward opening type that opens the opening.

  Although not shown, the window W suitable for the embodiment of the present invention is an inner opening type in which the suspension base side of the frame 2 is pivotally attached and the door end side is turned to the indoor I side, and the upper end side of the frame 2 is pivoted. A projecting mold in which the lower end side is projected toward the outdoor O with the wear side as the outer side, a flip-up type in which the lower end side of the frame 2 is pivoted as the pivot side, and the upper end side is tilted toward the outdoor O. In addition, there is an inward type in which the upper end side is inclined toward the indoor I, and further, there are a rolled-out type and a parallel extrusion type.

  Although not shown in the figure, the vertical-rotation type window W is such that the center part of the upper and lower eyelids in the frame 2 of the window W is vertically aligned with the upper part of the window frame 1 and the center part of the lower side part 11. The horizontal axis rotation type window W is pivotally attached to a shaft to be provided, and the horizontal axis of the window 2 has a central portion of the vertical rod which is the left and right of the frame 2 of the window W 1. It becomes the aspect which pivots to the axis | shaft provided in a horizontal direction in the center part, and rotates to an up-down direction.

  From this point of view, depending on the way of view, the vertical axis rotation type window W is an aspect in which the outer opening type window and the inner opening type window are connected, or the horizontal axis rotation type window W is inverted with the protruding type. Since the windows of the molds are connected to each other, this also makes it possible to implement the present invention.

  The frame 2 permanently holds the glass 3 integrally to ensure the daylighting function of the glass 3 and the function of blocking heat and air.

  In recent years, the frame 2 is often made of an aluminum extrusion mold material or a synthetic resin material in terms of operability, handling properties such as processing, and cost.

  As will be described in detail later, considering the realization of the present invention, the frame 2 is made of an aluminum extrusion mold material or a synthetic resin material that makes it easy to finish the finding surface 2a and the outer peripheral surface 2b to a flat surface. Is preferred.

  The glass 3 guarantees the viewability and the daylighting property in the window W, enables heat and air to be blocked, and as long as the glass 3 can be arbitrarily configured. For example, as shown in FIG. In order to make it, it is a double-glazed glass in which an air layer A is provided between a plurality of glass plates 31, and although not shown, the surface facing the air layer A of the glass plate 31 positioned on the outdoor O side It may be coated with a special metal film to improve the heat shielding property.

  In addition, as glass 3, in recent years there has been a tendency to use a multi-layer glass, but it may be composed of a single conventional glass plate 31, and although not shown, this single glass plate Of course, 31 may be made into a heat ray to form a dew condensation prevention structure, or it may be made into a piano wire to improve the strength against external force.

  Returning, the window W is provided in the window frame 1 so as to be openable, that is, for the connection mode of the frame 2 to the window frame 1 in the window W, the door end side is utilized using the pivot shaft 2c (see FIG. 2). Can be turned (see FIG. 5), or can be extruded in parallel on the entire surface without the pivot shaft 2a (see FIG. 6).

  In other words, it is preferable that the manner in which the frame 2 is connected to the window frame 1 can easily realize that the screen door 4 described later can be easily extended and retracted.

  From this point of view, as described above, the window W is formed in the illustrated outside opening type, as well as the inside opening type, the protruding type, the outside turning type, the inside turning type, and the vertical axis rotating type or the horizontal axis rotating not shown. It is preferable to be formed in a mold.

  On the other hand, although not shown, the upper end side of the frame 2 descends while sliding on the window frame 1 and the lower end side of the frame 2 protrudes to the outdoor O, or the suspension side of the frame 2 is a window, although not shown. When the frame 1 slides sideways while sliding and the door end protrudes to the outdoor O, it is considered that not only the primary direction but also the secondary direction force acts on the screen door 4, and the screen door 4 is twisted. In view of the above, it is understood that it cannot be said to be a very preferable connection mode.

  However, the present invention is not intended to exclude the realization of the open-out window W at all, and the present invention can be embodied as long as the expansion and contraction performance of the screen door 4 is ensured and the insect-proof function is ensured. It becomes the connection mode to make.

  For example, although not shown, when the screen door 4 is formed in a double structure so as to cope with twisting, the present invention can be realized even in the case of the open-type window W. There is no hindrance.

  Further, as described above, the frame 2 is formed in a frame shape. Therefore, an upper collar (not shown) as an upper end portion positioned along the upper side portion of the window frame 1, and the window frame 1 It has the lower collar 21 which is a lower end part positioned along the lower side part 1a.

  In this frame 2, a pair of vertical rods that are positioned so as to follow the pair of vertical portions 1 b in the window frame 1 by connecting the upper and lower rods 21 on the left and right sides, that is, in the illustrated case. In order to enable the rotation of the window W, the suspension frame 22 is a pivot side part pivotally attached to the window frame 1 and the door side wall 23 is a movable side part on the opposite side.

  In the frame 2, as shown in the figure, the door toe 23 is turned so that the suspension base 22 is the center of rotation (see the dashed line arrow a in FIG. 2).

  By the way, for example, a handle (not shown) provided on the door toe 23 is pushed to push the door toe 23 toward the outdoor O side, and the handle is pulled to pull the door toe 23 toward the indoor I side. As a result, the frame 2 rotates, so that the opening of the glass 3 can be opened and closed.

  Whereas the window frame 1 and the window W are formed as described above, the screen door 4 is basically configured to prevent insects from entering the indoor I from the outdoor O and is configured as follows.

  That is, the screen door 4 can be expanded and contracted so as to expand and contract following the opening / closing operation of the window W, and when the window W is opened, the insects from the outdoor O pass through the so-called vacant space and enter the indoor I. It is configured to prevent intrusion.

  Further, the screen door 4 can be configured to realize a usage state that functions as a screen door without opening and closing the screen door 4 itself, and can realize a so-called storage state when not in use.

  The screen door 4 is configured so as not to hinder the viewability and the daylighting of the window W even when in use as well as in the housed state.

  Therefore, in the present invention, as shown in FIG. 3, the screen door 4 includes an insect screen 41 that is formed to be stretchable and an end 41a of the insect screen 41, and the window frame 1 of the one end 41a. (See FIG. 2) Window frame side connecting means 42 that enables connection to the side, and connection to the window W (see FIG. 2) side of the other end 41b provided on the other end 41b of the insect screen 41. And window-side connecting means 43 that enable the above.

  The insect screen 41 can be expanded and contracted so as to expand and contract following the opening and closing operation of the window W. Therefore, in the illustrated case, the insect screen 41 can be expanded and contracted to be expanded and contracted.

  In other words, the insect screen 41 repeats the folding along the mountain fold line 41c and the valley fold line 41d in order to make the material formed into a rectangular tube shape foldable. The line 41c continues to the side valley fold line 41d, and continues to the upper valley fold line 1d and the side mountain fold line 41c by an upper conversion line 41e provided obliquely at a so-called corner.

  The side fold line 41c continues to the lower valley fold line 41d, and the conversion line 41e provided at the lower corner continues to the side valley fold line 41d and the lower mountain fold line 41c.

  As described above, by repeating the folding along the mountain fold line 41c, the valley fold line 41d, and the conversion line 41e, the accordion which is a musical instrument has an accordion-like form and can be expanded and contracted.

  Returning, the insect screen 41 may be freely configured as long as it is formed to be extendable and contracted, and therefore may have a structure that has been well known to date.

  For example, it may be formed into 18 mesh with PVC raw yarn, that is, it may have 18 warps and wefts in 1 inch (2.54 centimeters) square to form a mesh. This is advantageous in that the net 41 can be manufactured at a low cost and a relatively long-term durability against natural conditions such as rainwater and sunlight can be expected.

  As a result, the insect net 41 only needs to achieve an insect repellent function, so that it is formed of a metal yarn to improve durability, or a sputtering process is performed to exert a magic mirror effect. Or you can choose a free configuration.

  Further, from the viewpoint of ensuring air permeability, the insect repellent net 41 is not limited to a so-called net-like structure, and although not shown, for example, it is made of a non-woven fabric or an infinite number of sheet-like bodies. Of course, the holes may be aligned or scattered and opened.

  When the insect screen 41 is made of a nonwoven fabric or a sheet-like body having innumerable holes, it is suitable for folding processing and has high durability against repeated folding operations as compared with a case of a so-called widely used insect screen. It will be advantageous in that it can be expected.

  Returning, the insect screen 41 in the screen door 4 is formed in a bellows shape so that it can be expanded and contracted. In the illustrated case, the insect screen 41 is formed in a rectangular tube shape so as to be applicable to a window W having a square front shape.

  In order to prevent so-called unnecessary gaps from appearing between the rectangular insect-shaped insect screen 41, the window frame-side connecting means 42 and the window-side connecting means 43 have a rectangular front shape and the insect-insulating net. It is assumed that both ends 41a and 41b of 41 are integrally held.

  In the screen door 4, the insect screen 41 is connected to the window frame 1 and the window W by the window frame side connection means 42 and the window side connection means 43, and the window W is closed with respect to the window frame 1. When operating, it is sandwiched between the window frame 1 and the window W in a folded state, and when the window W is opened with respect to the window frame 1, it extends and appears between the window frame 1 and the window W. Shield the empty space.

  As long as the window frame side connecting means 42 does not appear in a desired connection state, that is, a gap through which insects from the outdoor O can pass easily by bringing the one end 41a of the insect screen 41 into close contact with the window frame 1 or the like, Any configuration may be selected.

  Further, even in the window-side connecting means 43, as long as the other end 41b of the insect screen 41 is brought into close contact with the frame 2 in the window W so that a gap through which insects from the outdoor O can pass easily appears. The configuration may be selected.

  However, when the present invention is embodied, the window frame side connecting means 42 and the window side connecting means 43 are provided detachably on the window frame 1 and the frame 2 of the window W, so that the screen door 4 can be replaced, or It is preferable to enable so-called water cleaning such as dust removal.

  Incidentally, even if the window frame side connecting means 42 and the window side connecting means 43 are not detachably provided on the window frame 1 and the frame 2 of the window W, and the screen door 4 cannot be replaced, the present invention can be implemented. Not disturbed.

  Hereinafter, the window frame side connecting means 42 and the window side connecting means 43 will be described. However, both of the connecting means 42 and 43 may have the same configuration. And description of the window side connecting means 43 will be omitted.

  FIG. 4 shows the window frame side connecting means 42 having the Velcro fastener 5, and one body 51 integrally held by one end 41 a of the insect screen 41 and the finding surface 1 a of the window frame 1. And the other body 52 that is integrally held in the body.

  The one body 51 is integrated with the one end 41a of the insect screen 41, and the other body 52 is integrated with the finding surface 1a of the window frame 1 by an appropriate means such as using an adhesive (not shown). To be held linked.

  Therefore, in the window frame side connecting means 42 having the Velcro fastener 5, the one body 51 is integrally connected to the one end 41 a of the insect screen 41, and the one body 51 is connected to the one body 51. By integrally connecting the connected other body 52 to the finding surface 1a of the window frame 1 by using an adhesive or the like, the one end portion 41a of the insect screen 41 can be integrally connected to the window frame 1. .

  In the Velcro fastener 5, the other body 52 connected to the one body 51 is fixed to the finding surface 1 a of the window frame 1 by closing the window W, and together with the window side connecting means 43, an insect screen. By sandwiching 41 between the window W and the window frame 1, for example, a predetermined fixing state can be realized by, for example, the adhesive solidifying over time.

  In addition, as shown, the window frame 1 and the frame 2 of the window W are made of an aluminum extrusion mold material, a synthetic resin material, or the like, so that the finding surfaces 1a and 2a finished flat can be obtained. And easy integration of the other body 52 using the adhesive to the finding surface 1a of the window frame 1 and the finding surface 2a of the window 2 of the one body 51 to the finding surface 2a. There is an advantage that becomes possible.

  The window frame side connection means 42 has the Velcro fastener 5 and is connected to the window frame 1, whereas the window side connection means 43 is also connected to the frame 2 of the window W in the same configuration and process. The

  That is, in the place shown in FIG. 4, the window-side connecting means 43 is provided on the one body 51 that is a connecting member integrally held by the other end 41 b of the insect screen 41 and the finding surface 2 a of the frame 2 of the window W. It has the other body 52 which is a to-be-connected member hold | maintained integrally.

  The one body 51 is integrated with one end 41a of the insect screen 41, and the other body 52 is integrated with the finding surface 2a of the frame 2 by an appropriate means such as using an adhesive (not shown). Concatenated and held.

  Therefore, in the screen door 4 shown in the figure connected to the window frame 1 and the window W as described above, the window frame 1 and the window W Appearing between the outdoor O (see FIG. 2) side and the indoor I (see FIG. 2) side to allow communication between the open side and the indoor I (see FIG. 2) side.

  In this outside opening type window W, the screen door 4 is folded so as to be sandwiched between the window frame 1 and the window W on the hanging side, and the hanging side and the door end side are In the meantime, the screen door 4 gradually spreads from the hanging side toward the door end side, and in a plan view, it has a fan shape.

  On the other hand, as shown in FIG. 6, when the window W is a full parallel extrusion type, the window W is wholly, that is, the frame 2 of the window W extends from the window frame 1 to the entire circumference. When projecting away in parallel to the outdoor O, a space allowing the communication between the outdoor O and the indoor I appears between the window frame 1 and the window W, but this space is made cylindrical from the state in which the screen door 4 is folded. Stretch and shield.

  From this, in the embodiment shown in FIG. 6, the screen door 4 is connected to the four sides of the frame 2 of the window W and the window frame 1, but in the embodiment shown in FIG. Is apparently connected to the upper side of the frame 2 of the window W, the three sides of the door toe 23 and the lower side 21 and the three sides of the upper side portion, the vertical portion 13 and the lower side portion 11 of the window frame 1. .

  Therefore, when the window W is formed in an outward-opening shape, a corresponding part in the screen door 4 in the frame 2 of the window W in the vicinity of the suspension ridge 22 ensures a smooth opening / closing operation of the window W, and has an insect-proof function. As long as it is not damaged, it can be said that it may be slightly folded or not folded.

  Returning, in the above-described screen door 4, since the window frame side connecting means 42 and the window side connecting means 43 are made of the Velcro fastener 5, it becomes possible to separate the screen door 4 from the window W and the window frame 1. The screen door 4 can be replaced, or the screen door 4 can be cleaned with water.

  In order to enable the screen door 4 to be attached to and detached from the window W and the window frame 1, the window frame side coupling means 42 and the window side coupling means 43 are not shown in the figure, instead of the Velcro fastener 5. A double-sided pressure-sensitive adhesive tape may be used although it is formed in a detachable structure by using a hook or does not facilitate attachment / detachment.

  The screen door 4 has the window frame side connection means 42 and the window side connection means 43. However, in the present invention, it is not necessary to open and close the window door 4 by holding the screen door 4 itself. It is not required that the frame side connecting means 42 and the window side connecting means 43 are ruggedly configured to make the screen door 4 a strength member, and the structure of the screen door 4 can be simplified compared to a screen door having a conventional frame structure, There is an advantage that the screen door 4 can be made inexpensive.

  FIG. 7 shows an embodiment in which the place where the screen door 4 is provided is changed. In this embodiment, the screen door 4 is formed between the finding surface 2 a in the frame 2 of the window W and the finding surface 1 a in the window frame 1. Suppose that it is provided between the outer peripheral surface 2b in the frame 2 of the window W and the inner peripheral surface 1b in the window frame 1 instead of between.

  Since the other configurations are not different from those described above, the same components are denoted by the same reference numerals in FIG. 7 and the description thereof is omitted.

  Even in this embodiment, the window frame side connecting means 42 and the window side connecting means 43 in the screen door 4 may be detachably connected to the window frame 1 side and the window W side, respectively, or fixedly connected. Of course it may be done.

  Furthermore, in the case of this embodiment, when the window W is opened and closed, the screen door 4 moves in the same manner as when the fan is spread or closed.

  Therefore, also in the case of this embodiment, when the window W is opened, the screen door 4 is provided between the window frame 1 and the window W. Will be realized.

  In the case of this embodiment, when the window W is closed, it is possible to make the frame 2 of the window W close to the window frame 1, so in the case of the above-described embodiment. In comparison, the so-called window thickness including the window frame 1 can be advantageously reduced.

  As described above, in the screen door structure of the present invention, one end 41a of the insect screen 41 in the screen door 4 has the window frame side connecting means 42 and the other end 41b has the window side connecting means 43. 41 can be connected to the window frame 1 side and the window W side by connecting means 42 and 43 on each side, and the screen door 4 can be provided without covering the window W.

  In the screen door structure of the present invention, the screen door 4 connected to the window frame 1 and the window W by the connecting means 42 and 43 on each side is formed with the insect screen 41 so as to be stretchable. When part or all of the window is separated from the window frame 1 and the opening is opened, the window W expands following the movement of the window W, and a part or the entire circumference of the space appearing between the window frame 1 and the window W is blocked. .
