Description

  The present invention relates to a screen door mounting device that is fitted together with an outdoor shoji in a sash window frame. An example of the “screen door” is an insect screen, but the insect screen widely includes a screen.

  As for the usage pattern of screen doors, when it is fitted in the window frame in parallel with the shoji, when it is fitted to a part of the shoji or door (in many cases, the upper part), and in the case of the mesh window attached to the window In such a case, one reed of the frame that is opened and closed by the insect repellent net is used as a net storage reed for the insect repellent net, and the wind-insulating net of the insect repellent net is supported therein. In any case, in this specification, an object into which a screen door is fitted will be referred to as a window frame.

  FIG. 10 schematically shows a conventional example of the present applicant as this type of screen door. According to this, a vertical gutter at one end of the screen door frame is a net storage rod 112, and a winding cylinder is provided therein. 121, the winding cylinder 121 has a winding spring 123 interposed between the central shaft 119 and the winding cylinder 121, which are always fixed, and one end of the winding cylinder 121 is wound around the central shaft 119 and the other end is wound up. Each is fixed to the cylinder 121. Therefore, when the insect net 115 wound on the winding cylinder 121 is pulled out, the winding cylinder 121 rotates against the elasticity of the winding spring 123, so that the insect net 115 is wound by the elasticity. It is done.

  In order to house the winding cylinder 121 in this way, the net storage basket 112 is an extruded shape with a wide internal space, and an opening / closing lid 113 is attached to the front surface thereof. In order to take a large internal space, the shape protrudes to the front surface, and therefore, the protrusion is conspicuous in terms of design with respect to the other ridges 116 when viewed from the indoor side. This problem can be solved by making the net storage ridges project to the outdoor side with respect to the other ridges (see FIG. 9), but then the convex portion inconveniently approaches the shoji on the outdoor side. In order to avoid this, there is a problem that a standard or existing window frame cannot be used, and a special window frame is manufactured exclusively, resulting in high costs.

  In view of the above circumstances, the present invention provides an apparatus for attaching a screen door in a window frame, which can use a standard or existing window frame without any inconvenience even when the net storage trough has a shape protruding outward. The task was to do.

  In order to solve the above-described problems, the present invention provides an indoor side piece and an outdoor side piece projecting from the indoor side end of each of the left, right, top and bottom frames that are framed so that the screen door can be fitted together with the outdoor shoji. In a sash window frame in which a deep groove is formed that opens inward of the frame, one ridge of the screen door projects to the outside of the other fold as a net storage fold, but is not flush with other folds on the indoor side. While it is flat, it is attached to each frame of the window frame with a belt-like support member that is connected to the deep groove portion and protrudes to the indoor side, and is surrounded by the left and right and upper and lower support members that protrude to the indoor side. An apparatus for attaching a screen door in a window frame is provided in which each screen is screwed to each support member by inserting the screen door.

  Since the screen door mounting device in the window frame is configured as described above, each ridge including the screen storage shed of the screen door is flush or almost flush when viewed from the indoor side, and the mesh ledge protrudes outside the room. In addition, by positioning the screen door on the indoor side via the support member, the distance from the outdoor shoji can be kept normal.

  As described above, according to the screen door mounting device in the window frame of the present invention, the appearance is good when the ridges are flush with each other when viewed from the indoor side, and it is brought closer to the indoor side through the support member. Therefore, there is no inconvenience in relation to the outdoor shoji even if a standard or existing width window frame is used, and there is an excellent effect that the cost is reduced without using a special window frame.

  Further, according to claim 2, by removing the screen door from the window frame, it is possible to further remove the net storage basket from the screen door together with the take-up cylinder, etc. The strength of the insect screen can be easily adjusted.

  1 to 7 show an embodiment. In this case, a screen door P is fitted in the window frame F of the sash in parallel with the outdoor shoji S. FIG. The shoji S is implemented as a “sliding shoji” that can be opened to the outside with the vertical axis moving sideways along the window frame F so that the entire window frame F can be opened and closed. It may be implemented as a different shoji. In addition, as shown in FIG. 8, in the upper and lower windows, the sliding window (not shown) and the screen door P are fitted to the upper window, and the sliding window board Sa or the sliding door is fitted to the lower window. There are various embodiments. FIG. 9 schematically shows the screen door of the present invention in comparison with the conventional example of FIG.

  The window frame F of the sash includes left and right vertical frames 1 and 2 and upper and lower frames 3 and 4, the lower frame 4 is formed in a step shape, the shoji S is fitted on the lower outer side, and the screen door P is fitted on the higher inner side. In addition, the screen door P is protruded and attached to the indoor side so that a space in which the net storage basket 11 can be extended is formed between the shoji S and the screen door P. For the attachment, each frame of the window frame F Support members 7, 7,... Made of extruded shapes such as aluminum and plastic are interposed between the door and the screen door P.

  Each frame 1, 2, 3, 4 of the window frame F has a deep groove 9 formed by projecting inner and outer pieces 9a, 9b at the indoor side end (FIG. 3), and an inward convex edge at the tip of the indoor side piece 9a. 10 is formed, and the front end of the outdoor piece 9b is formed in an inwardly inclined shape so that the support member 7 can be inserted and guided. Further, the support member 7 is provided with a leg piece 15 to be inserted into the deep groove 9 at the belt-like outdoor end portion and an end hanging piece 17 associated with the outdoor piece 9b. The leg piece 15 has an inwardly convex edge 10. The concave groove 18 is formed as a fulcrum or as an escape stopper. Therefore, it is easy to mount, and the fixing in the inner and outer width directions is ensured, and it is possible to strongly support the hooks 11, 12, 13, 14 by fixing them with screws 22.

  The screen door P is framed by a net storage rod 11, a vertical rod 12 in parallel therewith, and upper and lower rods 13 and 14, and a handle frame 8 is attached to the end thereof to pull out the insect net 16, and the upper and lower rods 13 are movable. , 14 are engaged. Among them, as shown in FIG. 3, the net storage trough 11 has a rectangular cross section that opens widely across the front surface and the inner half of the frame, and the attachment portion of the support member 7 is formed in a zigzag rib shape. The support member 7 is attached by screws 22 there. Further, the front surface is sealed with a lid 11a, and a screw pocket is provided on the front surface, and the upper end is screwed to the base 49 and the upper plate 51 for mounting the adjusting device 24, and the lower end is screwed to the lower connecting block 30.

  In this embodiment, as shown in FIG. 6, a center shaft 19 that is always fixed inside is provided in the net housing 11 and the center shaft 19 is the center. The winding tube 21 of the insect screen 16 is supported so as to rotate, and a winding spring 23 is interposed between the central shaft 19 and the winding tube 21, one end of which is the central shaft 19 and the other end is the winding tube 21. Are fixed to a bearing block 20 integral with each other. Accordingly, elasticity is accumulated in the winding spring 23 by the rotation of the winding cylinder 21 when the insect net 16 is pulled out, and when the handle frame 8 is released, the insect net 16 is wound around the winding cylinder 21 by the elasticity. Further, an adjustment device 24 that adjusts the strength of the winding spring 23 is provided at the upper end of the net storage rod 11. And in order to disconnect the adjustment cylinder 24 and remove the winding cylinder 21, the upper end raising / lowering shaft apparatus 25 is comprised in the upper end.

  The upper end lifting shaft device 25 constitutes a clutch with the central gear 26, a concave upper end cap 31 fitted to the upper end of the winding cylinder 21, a movable connecting piece 33 dropped into the concave portion, The movable connecting piece 33 is fitted on the upper end of the central shaft 19 and fixed with a rivet 37 thereto. The coil spring 35 is inserted into the central shaft 19 in the upper end cap 31 and receives the upper end of the movable connecting piece 33 so as to bias it upward. The movable connecting piece 33 has an upper end surface formed on the meshing clutch surface 39, a terminal shaft 41 protruding from the center thereof, and a driver groove 43 formed on the upper end of the terminal shaft 41. On the other hand, a lower shaft 38 protrudes from the center of the lower surface of the central gear 26 of the adjusting device 24, and a clutch surface 40 that meshes with the clutch surface 39 is formed at the lower end thereof.

  When removing the winding cylinder 21, it is first lifted. Then, the movable connecting piece 33 retracts into the upper end cap 31 against the elasticity of the coil spring 35 and responds accordingly, so that the lower end shaft 29 can be pulled out from the lower connecting block 30 by lifting the take-up cylinder 21, and just when attaching The reverse operation. Therefore, the attaching / detaching operation can be performed only by the vertical operation of the winding cylinder 21. In addition, it is not necessarily required that the winding cylinder 21 is removable. That is, a simple structure in which the central shaft 19 is directly connected to the central gear 26 without providing the upper end lifting shaft device 25 may be used.

  The terminal shaft 41 at the upper end of the winding cylinder 21 is exposed to the upper surface of the screen door P by being inserted into the shaft support hole 45 of the central gear 26, so that the central shaft 19 together with the central gear 26 is attached by attaching a screwdriver. The winding spring 23 can be strongly adjusted by this operation, as will be described later. In addition, 47 is a one-way clutch, 48 is a rotary damper, The speed at which the winding cylinder 21 rotates by the winding spring 23 is controlled.

  The adjusting device 24 is provided between a plastic base 49 screwed to the upper end of the net storage basket 11 and a metal top plate 51 for sealing it, and connecting pieces 49a and 51a project from each other. By doing so, the net storage basket 11 is connected to the upper basket 13. The lower connecting piece 49a is formed with a slit 53 through which the insect screen 16 passes. FIG. 4 shows the structure of the adjusting device 24 installed inside the base 49 without the top plate 51. In addition to the central gear 26 described above, the auxiliary gear 50 has a small diameter for driving. A swing lever 56 and a compression spring 52 as a coil spring are provided. In the figure, a part of the central gear 26 is notched for easy understanding.

  As shown in FIGS. 4 and 5, the base 49 has a peripheral wall 55 projecting from the periphery, and a half of the peripheral wall 55 is opened at the front surface, and a storage chamber for the compression spring 52 is provided at the back of the opening 57. 61 is formed, and the pivot shaft 62 of the swing lever 56 projects from the inner portion of the front blocking wall. The central gear 26 and the auxiliary gear 50 are pivotally supported on the base 49 and the upper surface plate 51, respectively. Reference numeral 63 denotes a shaft support hole of the central gear 26.

  The central gear 26 is a compound gear in which a ratchet gear 26b is formed under the large gear 26a (FIGS. 4 and 6), has an upper shaft 69 corresponding to the lower shaft 38, and has a winding cylinder at the center. 21 is formed, the clutch surface 40 is formed on the lower surface of the lower shaft 38, and the ratchet of the ratchet gear 26b is formed at a clearance angle corresponding to the rotation for pulling out the insect net 9. Further, the swing lever 56 has a “<” shape that refracts around the rotation shaft 62, and a claw 73 is formed on the tip side of the angle of attack of the ratchet and is exposed to the opening 57 at the base end. Since the push button 75 protrudes and the compression spring 52 pushes the rear surface thereof, when the push button 75 is pushed, the claw 73 at the tip is disengaged from the ratchet gear 26b, so that the stop of the central gear 26 is released. At this time, when the push is released at an appropriate position, the winding spring 23 is adjusted to be moderately weak.

  That is, if the winding cylinder 21 is fixed at this time, the elasticity accumulated in the winding spring 23 is relieved by the rotation (depolarization rotation) of the central shaft 19 due to the elasticity of the winding spring 23, and an appropriate time point. When the push button 75 is released to stop the rotation of the central shaft 19, the winding spring 23 is adjusted weakly. Further, when the central gear 26 is rotated by the driver and the central shaft 19 is rotated against the elasticity of the take-up spring 23 (positive rotation), in this case, the pawl 73 of the swing lever 56 is stopped when the rotation is stopped. Since the central shaft 19 is fixed on the ratchet gear 26b of the central gear 26, the take-up spring 23 is strongly adjusted. Further, since the driver groove 79 is also formed in the upper shaft 77 of the shaft of the auxiliary gear 50, if the auxiliary gear 50 is rotated, the central gear 26 can be lightly rotated by the gear boosting mechanism.

  7A shows a state in which the screen door P is assembled. When the mesh storage trough 11 is at the upper end, the connecting piece 49a of the base 49 and the connecting piece 51a of the upper plate 51 are inserted into the upper trough 13 and the lower end. Then, the connection piece 30a of the lower connection block 30 is inserted in the lower collar 14, and each is screwed. Therefore, in a state where the screen door P is removed from the window frame F, by removing the screws and removing the connecting pieces 49a, 51a and 30a, the net storage rod 11 is removed from the frame with the insect screen 16 and the handle frame 8 attached. (B), thus the interior can be cleaned and repaired.
