Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a side pulling sash having a screen door, a side pulling sash such as a sliding window, and a slide sash for vertically opening and closing.

[0002]

2. Description of the Related Art Conventionally, screen doors for sliding sashes such as horizontal sashes and vertical slide sashes are manufactured as sash frames, door plate type frame screen doors separate from sash frames, and sash upper and lower frames, and both sides. Generally, it is slidable by being fitted into a vertical frame rail.

[0003]

However, the frame screen door is generally arranged outside the glass screen,
Since the frame can not be made too large because it fits in the sash frame, it has less rigidity than a glass shoji frame, is easily deformed during use, and often falls off the sash frame. Since it is always arranged outside the glass shoji, it tends to get dirty and often gives an unpleasant feeling such as obscuring the visual field. Therefore, when the screen door is not used in winter, etc., it can be removed from the sash frame, washed with water and stored in a storage room, etc. without blocking the view, and the screen door will not be damaged and can be comfortably used again. However, in a narrow residential environment in an urban area, there is no space to store it when it is not in use, and such complicated work is difficult.In the end, the screen door is always placed on the sash frame and left in a dirty state. The reality is that

Therefore, as a solution, a roll screen having a structure in which an insect net can be wound and expanded on a take-up shaft inscribed with a torsion spring is stored in an opening vertical frame or a glass shoji vertical frame to prevent insect damage. An engaging rod fixed to a vertical edge of a net, which is a net, is detachably engaged with a vertical member, that is, a glass shoji vertical frame or an opening vertical frame, which opposes the engaging rod when the glass shoji is opened and closed. There has been proposed a sash with a roll screen having a structure in which the roll screen is expanded or wound according to opening and closing. Furthermore, there is also a sash with a screen door that has a structure in which a channel pocket that can be pulled out is formed on the vertical frame side of the glass shoji vertical frame, that is, the door end frame, and a foldable expandable pleat net is stored in the channel pocket. Proposed.

However, in the roll screen door or the pleated screen door, when the screen is expanded into the window frame opening, the upper and lower window frame rails interfere with each other to form a gap between the upper and lower edges of the screen and the upper and lower window frames, In addition to the drawback that the insect repellent effect is impaired, each screen has the following drawbacks.
That is, using a flat cloth net and expanding horizontally
In the roll screen door to be wound, the expansion and contraction rate of the net is different due to the difference in the load applied to the upper part and the lower part of the net itself. However, when winding the net, there is a drawback that unwinding is likely to occur in the upper part. On the other hand, in the case of a pleat screen door, when the mesh is expanded and held in the opening, the wire cord is sequentially passed through the mesh so that the mesh is not exposed to the wind and can be folded and stored in the channel pocket in order. In addition, it is necessary to tension the wire cord in the opening, but after penetrating the wire cord into the pleat net, it is also attached to the vertical moving rod that is fixed to the pleat net vertical edge, and further it is attached to the glass shoji vertical rod. Since the work is complicated, maintenance and inspection of the screen door itself is troublesome, and it is practically impossible to remove the screen part from the glass screen and clean it. Therefore, the present invention has improved the drawbacks of the conventional ones described above, and is intended to obtain a screen door and a laterally-pulled sash equipped with the screen door with a simple structure.

[0006]

To this end, a net formed by forming a plurality of pleats in the upper and lower stiles and the left and right stiles in parallel to the horizontal direction can be expanded and wound around a vertical take-up shaft. The curtain screen door, and the glass shoji vertical door frame are provided with a channel pocket that opens to the door side, and a lid rod that covers the channel pocket and closes the hollow portion is detachably arranged. The upper and lower ends of the sliding door are vertically guided and housed in the upper and lower sashes respectively from the edge, and one end of a guide rail having a mesh attaching / detaching mechanism is fixedly connected to form a front U-shape. In the channel pocket, there is housed a winding shaft that can be rotated in the forward and reverse directions according to the appearance of the guide rail with respect to the upper and lower frames of the shoji, and a net having a pleat provided in the horizontal direction on the winding shaft. Winding with the side edges fixed Together, it is made to engage the other side Tateen to Futa杆.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Since the present invention has the above-described construction, when using a screen door in a horizontal sash, for example, if the lid rod fitted into the channel pocket of the glass shoji vertical frame is pulled out, the upper and lower guides are guided. The rails are also interlocked and pulled out horizontally from the upper and lower frames of the glass shoji, and the net wound around the winding shaft is sequentially expanded while being attached to and held by the upper and lower guide rails, opening the open part of the glass shoji. Can be completely covered. Then, by the guide rails fixed to the upper and lower ends of the lid rod, the lid rod moves laterally while keeping the vertical state even when the lid rod is pulled out, and closes the upper and lower frames without a gap. Next, if you close the opened glass shoji,
The upper and lower guide rails are guided and stored in the upper and lower frames of the glass shoji, and the net is also wound around the winding shaft while being removed from the upper and lower guide rails and stored in the channel pocket of the glass shoji vertical frame, and the lid rod is the channel pocket. And the channel pocket is closed. At this time, since the net and the screen door member are stored and fixed inside the glass shoji member, the opening and closing operation can be performed as a single glass shoji screen.

Further, since the net is provided with a plurality of pleats that are parallel to each other in the horizontal direction, when the net is expanded from the winding shaft, the pleat groups divided by the respective fold lines alternate in the vertical direction. Since it slightly inclines in the opposite direction, it is possible to prevent the middle slack and the waving phenomenon, and it goes without saying that this can be applied not only to the above-mentioned lateral pulling sash but also to the vertical opening / closing slide sash.

Even if the fastener (16) is not provided over the entire length of the side walls of the guide rails (1) and (2) which come into contact with the mesh, a piece of the fastener (16) of an appropriate length is appropriately provided at the intermediate portion. The upper and lower edges of the net (C) are sewn together at positions corresponding to the piece positions of the net (C) when the net (C) is expanded, so that they can be attached to and detached from each other. By doing so, it is possible to reduce the wear due to the engagement of the mesh (C) itself with the fastener (16), and it is possible to obtain a favorable result in maintenance management.

A pinion gear (19) meshes with a rack gear belt (17) arranged on the guide rails (1) and (2) to horizontally move the guide rails (1) and (2). It rotates with. And the pinion gear (1
9) is fixed to the upper and lower ends of the winding shaft (20) so as to transmit the rotational force to the winding shaft (20). On the other hand, the winding shaft (20) is provided with a channel pocket (1) of the door frame (13).
3a) Support brackets (21) provided on the upper and lower ends

In FIGS. 5 and 6, the glass screens (A) and (B) are left open and the lid rod (3) is attached to the door end frame (1).
3) Pull out from the upper and lower guide rails (1), (2)
In conjunction with that, glass shoji (A) and (B), respectively
Guide channels (4a), (5) provided in the longitudinal direction of the upper frame (4), (4 ') and the lower frame (5), (5').
derived from a). At this time, the rack gear belt (1) arranged on the upper and lower guide rails (1), (2)
7) and the pinion gear (19) integrated with the take-up shaft (20) mesh with each other, so that the take-up shaft (20) is meshed (C).
The net (C) covers the vertical U-shaped opening formed by the upper and lower guide rails (1) and (2) and the lid rod (3) without any gap. When the mesh (C) is expanded as described above, the upper and lower edges of the mesh (C) are pressed toward the fastener (16) side by the guide roller (18a) at the outlet of the channel pocket (13a). The mesh (C) is expanded while the meshes of the mesh (C) are fitted into and retracted from the fine hairs of the fastener (16) so as to be entangled with each other. Therefore, the window frame open part constituted by the upper and lower window frames (6) and (7) and the vertical frames (8) and (8 ') includes the upper and lower guide rails (1) and (2) and the lid rod (3). In addition, the door frame (13) can be used as an intermediary material to cover the net (C) so as to prevent insects and the like from entering. The expanded net (C) has its vertical edges tensioned by the take-up shaft (20) and the lid rod (3) with appropriate tension, and the upper and lower edges of the upper and lower guide rails (1), Since it is engaged with (2), it can be prevented from being peeled off or opened by gusts or the like.

The mesh (C) has a structure in which warp threads and weft threads made of polyester, etc. are entangled with each other to form a mesh, and the mesh cannot be easily loosened. Further below (FIGS. 9 and 10)
As described above, by providing the pleat-shaped folds (27) in a direction perpendicular to the winding / expanding direction, the net (C) of the folds (27) itself even when expanded. Due to the waist strength possessed by, the slack of the net (C) can be prevented without a strong tension in the horizontal direction. Further, providing the pleated folds (27) parallel to the window frame opening in the horizontal direction gives a visually sensation of release, so that the entire narrow window frame opening is covered with the net (C). In the case of light, the pleats that are slightly tilted with respect to the vertical direction give a subtle refraction to the incident light to soften the oppressiveness and the feeling of oppression, and at the same time, obtain an aesthetic modeling by light. You can

The fastener (16) fixedly arranged on the guide rails (1) and (2) is shown in FIG. 7 and an enlarged sectional view.
As shown in Fig. 2, flexible fine hairs (16b) made of polyester or nylon are woven into a belt-like cloth made of polyester, the ends thereof project almost at right angles to the belt-like cloth (16a), and the tips thereof are fine hairs. It is molded into a spherical grip (16g) larger than the diameter of (16b). Grip (16
The mesh having a diameter larger than the diameter of g) is fitted into the grip so that the warp (C1) and the weft (C2) of the mesh are hook-engaged with the grip jaw. Net expanded to the opening (C)
When an external pressure such as a wind pressure acts on the net, the upper and lower edges of the net are pulled toward the center of the net, so that the net yarn is hooked almost at right angles to the fastener fine bristles (16b). Of course, at this time, the external pressure component force in the out-of-plane direction also acts on the upper and lower edges of the net, but it is smaller than the in-plane component force, and the warp threads forming the mesh mesh are in contact with this out-of-plane direction component force. , The weft thread is hooked on the jaw (16g), so the mesh can be easily gripped (16g).
It has a structure that does not come off from g). As the mesh expands and winds over a long period of time, mesh mesh repeatedly appears and disappears on the fine hair grip, but since the fine hair tip grip is spherically shaped, it prevents damage to the warp and weft threads of the mesh. It has the effect of being.

The fine hairs of Velcro fasteners which are generally commercially available today have a structure in which the tips of the hairs are formed in a U shape in a hook shape, and the U-shaped hooks engage the mating hooks with hooks. Although it is effectively bonded to the woven fabric, when the mesh net is repeatedly attached to and detached from this fine hair, the warp and weft of the net are each made up of a plurality of ultrafine threads twisted together, and the thread at the tip of the hook. Is pulled, the twisted yarn is unraveled, and the ultrafine yarn is cut, resulting in a decrease in durability. Therefore, in order to prevent the twisted yarn from loosening, it is generally used by impregnating the resin to strengthen the waist of the warp and weft threads of the net, but if the waist is too strong, the net thread will not be easily between the fastener and the thin hair. They couldn't go in, and it became the same phenomenon as putting paper on the lawn, and it became impossible to engage. In addition, since it is necessary to use a net yarn that is soft enough to entangle the net yarn with the hook-like fine hair, it is necessary to reduce the amount of resin impregnated, and the twisted yarn is easily unraveled as described above. There is. Further, the Velcro fastener having the hook-shaped tips cannot be used for a net which is frequently repetitively attached and detached. Therefore, as described in detail above, by making the fastener hair tips spherical, the net can be easily attached to and detached from the fastener fine hair regardless of the strength of the waist of the net thread, and the knotting yarn is loosened by being pulled by the hair tips. This phenomenon will be prevented.

On the other hand, in FIGS. 5 and 6, the lid rod (3) or the glass screens (A) and (B) are horizontally moved to move the lid rod (3) horizontally to the door end frame (13) side. For example, the upper and lower guide rails (1) and (2) are also interlocked with the upper and lower frames (4), (4 ') and lower frames (5), (5') of the glass screens (A) and (B), respectively. The guide channels (4a) and (5a) provided in the longitudinal direction of the are stored. At this time, the mesh (C) is formed by the engagement of the rack gear belt (17) arranged on the upper and lower guide rails (1) and (2) and the pinion gear (19) integrated with the winding shaft (20). ) Is taken up by the take-up shaft (20), and at the same time, the net (C)
The upper and lower edges are wound on the winding shaft (20) while being stripped off from the fastener (16).

As shown in FIG. 10, a coupling pipe (20a) having an open groove in the longitudinal direction is fitted on the winding shaft (20) so as to clamp the winding shaft (20) from the outside of the net (C). Have been combined. In addition, one side edge of the net (C) is adhesively bonded to the outer peripheral surface of the coupling tube (20a), or a fastener (not shown) is bonded to the outer peripheral surface of the coupling tube (20a). Although the one side edge of the net (C) is fixed by engaging with it and the sandwiching is performed, the latter structure using the fastener is easier to attach and detach the net (C). , Screen doors are easier to maintain. The holding force is adjusted so that the net (C) can be loosely wound. Therefore, the winding shaft (20)
When the pitch diameter of the pinion gear (19) integrated with and the winding outer diameter of the wound net (C) are close to each other, the winding speed is increased or decreased by the elastic elasticity of the net (C). By synchronizing with the horizontal movement speeds of (1) and (2) and increasing the winding outer diameter, the pinion gear (1
As a result of causing a considerable difference from the pitch diameter of 9), the coupling pipe (20a) is wound even when a rotational force of a predetermined amount or more is applied to the winding shaft (20). By spinning around the shaft (20), the winding speed and the horizontal movement speed of the upper and lower guide rails (1) and (2) can be synchronized, and the horizontal movement of the upper and lower guide rails (1) and (2) can be achieved. The winding operation can always be performed smoothly regardless of the moving speed and the winding amount of the net (C) around the winding shaft (20).

FIG. 10 is a schematic external view showing the screen door structure, and FIG. 11 transmits a rotational force to the winding shaft (20) as the upper and lower guide rails (1) and (2) move horizontally. It is another embodiment. That is, the rack gear belt (1
7) and a pinion gear (19) integrated with the winding shaft (20) are used instead of transmitting rotational force, and thread winding pulleys (24) are fixed to the upper and lower ends of the winding shaft (20). The tension cords (25), whose both ends are fixed to both ends of the upper and lower guide rails (1) and (2), are wound around the respective bobbin winding pulleys (24) in opposite directions. In addition, when fixing both ends of the upper and lower tension cords (25) to both ends of the upper and lower guide rails (1) and (2), one end side thereof is fixed so as to be tensioned via a winding spring (26). Has been done. By winding the tension cord (25) around the spool (24), the torque is transmitted to the winding shaft (20) as the upper and lower guide rails (1) and (2) move horizontally. You can

Next, FIGS. 13 and 14 show another embodiment different from the above embodiment of the method for transmitting the rotation to the winding shaft.
That is, the support arm which removes the pinion gear, the rack belt, and the spool, and rotatably supports the upper and lower ends of a hollow winding shaft (20) inscribed with a known torsion spring (not shown). (29) is pivotally supported together with the coil spring (30) on a support table (28) fixedly arranged at the upper and lower ends of the channel pocket (13a) of the door frame (13) to support the coil spring (30). The winding shaft (20) constantly presses the guide rails (1) and (2) by elastic force. The mesh (C) wound around the winding shaft (20) has mesh meshes on the fine hairs of the fastener (16) fixed to the guide rails (1) and (2) at the winding outer peripheral contact portion. The guides (1) and (2) are horizontally moved, and the net (C) is sequentially fed out while meshing with the fastener in the tangential direction of the winding outer circumference as the guide rails (1) and (2) move horizontally. At this time, the winding shaft (20) is rotated while amplifying the biasing force of the torsion spring inscribed in the hollow portion.

The actual frame thickness of the glass sliding door door sill (13) is small (18 to 25 mm), and the winding shaft (13a) is used to wind the net expanded to the entire opening width and store it in the channel pocket (13a). Since the outer diameter of 20) cannot be made too large (9 to 12 mm), the winding diameter of the torsion spring stored in the hollow take-up shaft is also small, and its urging force is also slight. That is, the above-mentioned urging force is a slight force such as the rotation of the winding shaft (20) and the rewinding of a loose net, and it is between the guide rails (1) and (2) and the upper and lower frames for storing them. It does not exceed friction. When the opening / closing operation of the screen door is performed, the lid rod (3) engaged with the upper and lower guide rails (1) and (2) is stopped at a free position.

Next, when the expanded mesh (C) is closed, the tips of the fasteners (16) penetrate the mesh rods extending in the tangential direction at the winding shaft portion, and the mesh on the inner circumference of the winding. The rotation force can be transmitted to the outer circumference of the mesh mounted and wound, and the mesh (C) is rewound lightly in combination with the urging force of the winding shaft (20). As described in detail above, the fastener structure of the present invention enables the net to be wound and stored by reducing the winding shaft diameter and the torsion spring winding diameter even on a frame having a small expected size, which is extremely simple as compared with the above embodiment. It is intended to provide a compact screen door structure.

FIG. 15 and FIG. 16 are internal views of a slide sash in which the glass screens (A) and (B) can be moved up and down along the vertical frames (33) on both sides. It is similar to the structure rotated by 90 degrees with a glass shoji (A).
(B) has a known structure in which the weight of the shoji is balanced by a spiral shaft or a balance weight (not shown) internally stored in the vertical frame (33) and can be locked at any position. Similar to the horizontal pulling sash, the guide rail (31) is retractably housed in the vertical frame (35), and the screen door horizontal frame (32) is fixedly engaged with the vertical rail (36). ). The drawing shows an embodiment in which the pleat folds of the net C are wound and mounted in parallel with the winding shaft (20), but the pleat folds are perpendicular to the winding shaft (20) as in the above embodiment. You may wind and attach it in the direction.

EFFECTS OF THE INVENTION Since the present invention has the above-described structure, it has a simple structure. When the screen door is not used, the screen door member is stored in the glass shoji sash frame and a storage place for the screen door member is required. In addition, it is easy to open and close, and when the glass sliding door is opened, the opened part is completely covered with a net, and maintenance is easy, and the flare phenomenon due to the looseness of the net is prevented. It has an excellent effect that the appearance of the part can be improved.
