Description

The present invention relates to a horizontal pulling roll screen door in which the upper and lower ends of the net, or at least the engaging elements attached to the upper ends of the net, are held by the upper and lower inner rails in the screen door frame to open and close the net. ..

In the horizontal pulling roll screen door, when the fastener-shaped engaging elements attached to the upper and lower ends of the net are engaged and held by the upper and lower inner rails provided in the upper and lower screen door frames to make them slidable, the net opening / closing operation is performed. In order to make the net smooth, the net is manufactured so as to give a slight margin between the engaging elements at the upper and lower ends of the net with respect to the dimension between the upper and lower inner rails. However, when the engaging elements are attached to the upper and lower ends of such a net, the finished dimensions of the net are not necessarily the same due to the tolerance of cutting the net and the tolerance of the attachment position of the engaging elements to the upper and lower ends of the net. It may not be suitable for smooth opening and closing, or the stretched net may have unsightly slack, and in these cases, the customer will request improvement.

Therefore, when attaching the engaging elements to the upper and lower ends of the net, it is out of the question if the distance between the engaging elements at the upper and lower ends of the net is too short or too long with respect to the dimensions between the upper and lower inner rails. However, since the net used in the screen door itself has some elasticity and the length of the net in the vertical direction is relatively long, the net is extended in the stretched state of the net on the screen door frame. A certain amount of extension force is applied to the net in the vertical direction so that the degree of If this is increased, the slack of the net in the stretched state can be removed, and the opening and closing operation of the net can be facilitated when opening and closing the net.

Then, if the above-mentioned configuration in which the upper inner rail is moved upward in the stretched state of the net is adopted, it can be an effective means instead of improving the dimensional accuracy between the upper and lower inner rails at the time of manufacturing the net. If the error of the finished dimension of the net is allowed by such means, the slack of the net can be removed only by applying gravity such as a lower inner rail to the lower end of the net in the stretched state of the net. Can be made possible.

The technical problem of the present invention is that during the opening / closing operation of the net in the horizontal pulling roll screen door, the above-mentioned slack does not particularly hinder the movement of the movable stile, but rather helps the smooth movement of the net, however. When the net is fully extended, the above slack may be conspicuously judged to be a defect. Therefore, when the movable stile moves to the net extension position, the upper and lower inner rails move up and down to the position where the slack is eliminated. It is an object of the present invention to provide a horizontal pulling roll screen door that can be moved so as to solve the above-mentioned problems such as sagging.

In order to solve the above problems, according to the present invention, the winding shaft of the net stretched in the screen door frame is rotatably held in the winding box constituting the side frame of the screen door frame, and the winding is performed. In a horizontal pulling roll screen door in which a net having one end attached to a shaft can be wound up and the net can be stretched in a screen door frame by horizontal pulling of a movable stile attached to the lead-out end of the net, the above net is used. An engaging element is attached along the upper end thereof, and by engaging the engaging element with an upper inner rail arranged in the upper frame of the screen door frame, the net is opened and closed by horizontal pulling along the upper frame. The upper inner rail is made possible, and the upper inner rail is kept horizontal with respect to the upper frame via a link mechanism provided with a plurality of support arms for supporting the upper inner rail, and the net of the upper inner rail is maintained. It is supported as something that can be moved upward by pressing in the extension direction, and when the movable frame moves to the extension position of the net that reaches the receiving frame facing the take-up box on the upper part of the movable frame. The operation portion formed in a part of the link mechanism is pressed toward the frame side to move the upper inner rail upward so as to eliminate the slack of the net, while the lower end of the net is a screen door. When the horizontal pull is guided by a guide that can be fixed or raised and lowered on the lower frame of the frame and the upper inner rail moves upward at the extension position of the net, the lower end of the net is held by the guide and added to the net or the net. Provided is a horizontal pulling roll screen door characterized in that it is held in a position that eliminates slack in the vertical direction by its own weight of the guide.

In a preferred embodiment of the horizontal pulling roll screen door according to the present invention, a link mechanism for supporting the upper inner rail on the upper frame is provided between the upper inner rail and the upper frame at least in the longitudinal direction of the upper inner rail. The operation is performed at the lower end of the support arm located above the movable stile at the extension position of the net, which is configured by rotatably connecting both ends of the support arm having a fixed length at a plurality of locations including both ends. It is desired to be configured as a first link mechanism in which a portion is attached and a pressing portion that faces the operation portion and presses it toward the frame side is formed on the upper portion of the movable stile.

Further, in another preferred embodiment of the horizontal pulling roll screen door according to the present invention, the link mechanism for supporting the upper inner rail on the upper frame is slidable in the longitudinal direction along the side surface of the upper inner rail. An engaging shaft portion to be engaged is provided at one end, and the other end is provided with a plurality of support arms having a constant length rotatably connected to the upper frame, and at least at a plurality of locations including both ends in the longitudinal direction of the upper inner rail. The operation is performed on the lower end of the support arm located above the movable stile at the extension position of the net, which is configured by connecting the positioned support arm with a single connecting rail at the engagement shaft portion. It is desired to be configured as a second link mechanism in which a portion is attached and a pressing portion that faces the operation portion and presses it toward the frame side is formed on the upper portion of the movable stile.

In the embodiment in which the second link mechanism is adopted, the upper inner rail is not directly connected to the support arm rotatably connected to the upper frame, and the connecting portion with the support arm is slid. Since it is movable, the upper inner rail moves upward without lateral movement due to the pressing of the operating portion by the pressing portion, so that the upper inner rail extends over the stretchable range of the net in the longitudinal direction of the upper frame. Can be provided.

Further, in another preferred embodiment of the horizontal pulling roll screen door according to the present invention, an engaging element is attached along the lower end of the net, and the engaging element is fixedly or vertically movable on the lower frame of the screen door frame. By engaging with the lower inner rail as the guide, it can be configured to guide the lateral pull along the lower frame of the net.

Then, in the case of this embodiment, the lower inner rail is supported by the support arm so as to be able to move up and down while maintaining the horizontal position, and the movable stile moves to the fully extended position of the net under the movable stile. When this is done, it may be configured as having an operation unit that comes into contact with a part of the support arm or the lower inner rail in the lower frame and moves the lower inner rail downward so as to eliminate the slack of the net. can.

Further, in the horizontal pulling roll screen door having the above-described configuration according to the present invention, the take-up box can be arranged on either the left or right side of the screen door frame, and the hanging source can be set on either the left or right side of the screen door frame. At the same time, it is possible to make the change, and in that case, the configuration of the screen door frame may be vertically symmetrical, thereby changing the direction of the net upholstery surface. By installing the winding box upside down, the take-up box can be arranged on either the left or right side of the screen door frame.

Further, in order to solve the above-mentioned problems, according to the present invention, the winding shaft of the net stretched in the screen door frame can be rotated in each winding box constituting the left and right side frames of the screen door frame. By holding the net, it is possible to wind the net with one end attached to each winding shaft, and by pulling the movable stile attached to the lead-out end of the net, the net can be stretched in the screen door frame by double pulling. In the pull roll screen door, the engaging elements are attached to both nets along the upper ends thereof, and the engaging elements are engaged with the upper inner rails arranged in the extension region of each net in the upper frame of the screen door frame. By doing so, the net can be opened and closed horizontally along each upper frame, and each of the upper inner rails has a plurality of support arms that support the upper inner rail in the extension region of each net in the upper frame. The upper inner rail is supported by a link mechanism provided with a link mechanism so as to be able to move upward by pressing the upper inner rail in the net extension direction. Presses the operation unit formed in a part of the link mechanism toward the combination position side and moves the upper inner rail upward so as to eliminate the slack of the net when the screen moves to the combination position. On the other hand, the lower end of the net is guided by a guide fixed to the lower frame of the screen door frame or can be raised and lowered, and when the upper inner rail moves upward at the extended position of the net, the guide is provided. Provided is a double-door horizontal pulling roll screen door characterized in that the lower end of the net is held by the net, and the net or a guide attached to the net is held at a position where the slack in the vertical direction is eliminated by the weight of the net or a guide attached thereto.

As described in detail above, in the horizontal pulling roll screen door according to the present invention, the degree of extension of the net in the stretched state of the net on the screen door frame is set to be within an allowable range with respect to the net. A certain amount of extension force is applied in the vertical direction, but such extension force is not applied when the net is opened and closed, and the operation is easily performed by using the movement of the movable stile. Therefore, in the manufacturing stage of the screen door, when attaching the fastener-shaped engager to the upper and lower ends of the net, the finished dimensions of the net may vary slightly due to the cutting of the net and the tolerance of the attachment position of the engager to the net. Even if it occurs, the slack of the net in the stretched state can be removed, and the operation at the time of opening and closing the net can be facilitated.

The horizontal pulling roll screen door according to the present invention can be applied as a screen door for shading, blindfolding, insect repellent, etc. at a building opening, and FIGS. 1 to 4 show the whole of the first embodiment of the horizontal pulling roll screen door. The state of the movable stile 9 attached to the net 6 during the opening / closing operation (FIGS. 1 and 2) and the state when the movable stile 9 attached to the net 6 reaches the fully extended position of the net. (FIGS. 3 and 4) are shown by a front view and a side sectional view in which a part of the screen is broken.

Explaining the configuration of the first embodiment in detail, first, the screen door frame 1 in the horizontal pulling roll screen door is a winding box 2 for accommodating the net 6, and the net 6 is completely at a position facing the winding box 2. It is arranged so as to connect the receiving frame 3 for hooking the movable frame 9 with a lock member 10 such as a magnet or a hook when in the extended state, and the upper ends of the winding box 2 and the receiving frame 3 thereof. It is composed of an upper frame 4 and a lower frame 5 arranged between the lower ends thereof.

The take-up box 2 constituting one of the pair of side frames of the screen door frame 1 rotatably holds the take-up shaft 7 (see FIGS. 1 and 15) of the net 6 inside the take-up box 2. A place where the take-up shaft itself is rotated by the rotational urging force of a coil spring built in the shaft 7 so that the net 6 having one end attached to the take-up shaft 7 can be taken up and the opening / closing operation mechanism of the net is configured. The net can be stretched from the winding box 2 into the screen door frame 1 along the upper frame 4 and the lower frame 5 by the lateral pulling operation of the movable frame 9 attached to the lead-out end of the net 6. It is configured as follows. The net 6 has some elasticity like the existing one.

Fastener-shaped engaging elements 12a and 12b, which are often used for clothing and the like, are attached to the net 6 along the upper and lower ends thereof, and in the upper frame 4 and the lower frame 5 of the screen door frame 1, FIG. By engaging the engaging elements 12a and 12b with the upper inner rail 13a and the lower inner rail 13b arranged in the upper frame and the lower frame, as clearly shown in the above frame, along the upper frame and the lower frame. The net 6 can be opened and closed by pulling it sideways. The upper and lower inner rails 13a and 13b are provided with slits 14a and 14b along the longitudinal direction thereof, and the engaging elements 12a and 12b are engaged with the inner edges of the slits and attached to the upper and lower ends of the net 6. It guides the engager in a retaining state.

As will be described in detail below, the upper inner rail 13a is attached to the upper frame 4 via a link mechanism provided with a plurality of support arms that support the upper inner rail 13a so as to be movable up and down. However, as the link mechanism, either the first link mechanism 20 shown in detail in FIGS. 5 to 8 or the second link mechanism 30 shown in detail in FIGS. 9 to 12 is used. It is desirable to use it selectively. However, the present invention is not limited to the first and second link mechanisms, and the upper inner rail 13a can be moved upward by pressing the link mechanism in the net extension direction while the upper inner rail is maintained horizontally. Anything that supports it as a thing is sufficient.

In this first embodiment, the upper inner rail 13a is held by the upper frame 4 by the link mechanism, but the lower inner rail 13b attached to the lower part of the net 6 is as can be seen from FIG. It is configured to be housed in the lower frame 5 in a state where it can move slightly up and down, and to guide the lower end of the net 6 in a state where the weight of the lower inner rail 13b itself is loaded on the stretched net 6. ing. However, the lower part of the net 6 is guided by a guide (for example, the lower inner rail 13b) that can be fixed or raised and lowered to the lower frame 5 of the screen door frame 1, and the upper inner rail is guided at the extended position of the net. When the 13a moves upward, the lower end of the net is held by the guide, and is held at a position where the slack in the vertical direction is eliminated by the weight of the net 6 or the guide added to the net 6.

Next, as shown in FIGS. 5 to 8, the first link mechanism 20 for supporting the upper inner rail 13a on the upper frame 4 will be described. The first link mechanism 20 is the upper inner. While maintaining the horizontal posture, the rail 13a is pressed by the pressing portion 9a at the upper end of the movable frame 9, which will be described later, on the receiving frame 3 side of the upper inner rail 13a, that is, the pressing of the net in the extension direction. The upper inner rail itself is supported as being able to move upward.

More specifically, the first link mechanism 20 has a constant length of support arms between the upper inner rail 13a and the upper frame 4 at least at a plurality of locations including both ends in the longitudinal direction of the upper inner rail 13a. Both ends of the 21 are rotatably connected to each other, and the upper inner rail 13a is hung horizontally. As shown in FIG. 7, the support arm 21 itself has a pair of levers 21a that support both side surfaces of the upper inner rail 13a integrated with a rotatable connecting shaft portion 21b to the upper frame 4. It is desirable that the connecting shaft portion 21b be attached to the upper frame by using a support pin or the like that penetrates the upper frame and the connecting shaft portion.

Further, in the illustrated embodiment, the support arm 21 is connected to the support shaft 16a erected on the substrate 17a fixed in the concave grooves 15a on both side surfaces of the upper inner rail by adhesion or the like. The hole at the lower end of the lever 21a is rotatably fitted, but the lever 21a is rotated with respect to the support shafts 16a provided on both side surfaces of the upper inner rail 13a by any means without limitation. It can be attached freely.
In the embodiment shown in FIG. 1, the support arms 21 are attached to both ends of the upper inner rail in the longitudinal direction in order to connect the upper frame 4 to the take-up box 2 and the receiving frame 3. The support arm was rotatably attached to the corner member 4a fitted between the members, while the support arm 21 was attached to the intermediate portion of the upper frame 4 to the top plate of the upper frame 4. Although the support arm is rotatably attached to the bracket 4b, the attachment mode of these support arms 21 is not limited to them, and the support arm 21 can be attached to the upper frame 4 or the like by appropriate means.

The first link mechanism 20 described above moves the upper inner rail 13a suspended in the upper frame 4 to the extension position of the net 6 where the movable frame 9 abuts on the receiving frame 3. The movable stile 9 is to be moved upward by the moving operation itself, and therefore, an operation formed at the lower end of the support arm 21 on the receiving frame 3 side of the upper inner rail 13a which is a part of the first link mechanism 20. The portion 21c is pressed toward the receiving frame 3 by the pressing portion 9a provided on the upper portion of the movable rail 9, and the support arm 21 is rotated at the support point to the upper frame 4, as shown by the arrow A in FIG. At the same time as the upper inner rail 13a moves to the receiving frame 3 side, it moves upward while maintaining the horizontal position, and as a result, it is formed so as to take the position shown in FIG.

The operating portion 21c provided in the first link mechanism 20 is provided at the lower end of the support arm 21 in the first link mechanism 20 and is provided for net extension by the pressing portion 9a provided in the upper part of the movable stile 9. By pressing during operation, the first link mechanism 20 can be formed at a position suitable for being pressed toward the receiving frame 3. Then, if the operating portion 21c is pressed toward the receiving frame 3 by the pressing portion 9a provided on the upper portion of the movable stile 9, the upper inner rail 13a can be moved upward so as to eliminate the slack of the net 6.

As described above, after the pressing portion 9a provided on the upper part of the movable stile 9 for pressing the operating portion 21c of the first link mechanism 20 comes into contact with the operating portion 21c, the pressing portion on the movable stile As shown in FIG. 6, the upper moving position of the upper inner rail 13a when the upper surface of the 9a pushes up the operation portion 21c of the first link mechanism 20 is the holding position of the upper inner rail 13a in the extended state of the net 6. Therefore, when the net 6 is assembled to the screen door frame 1 and the net is in a stretched state, that is, when the movable stile 9 is brought into contact with the frame 3, the net becomes slack or becomes excessively tense. In some cases, by adjusting the height of the upper surface of the pressing portion 9a in the movable stile 9, it is possible to adjust the height to an appropriate state without the slack.

In the first link mechanism 20, since the upper inner rail 13a is rotatably connected to the upper frame 4 by the support arm 21 at a plurality of positions, the pressing portion 9a of the movable stile 9 operates the lower end of the support arm. When the portion 21c is pressed, each support arm 21 rotates about the connecting portion with respect to the upper frame 4 and moves the connecting portion with each upper inner rail 13a along an arcuate locus, so that the upper inner rail 13a Each part of the above moves upward and at the same time moves laterally to the receiving frame 3 side. Therefore, it is necessary to provide a space necessary for lateral movement of the upper inner rail 13a in the upper frame 4.

Next, the second link mechanism 30 for supporting the upper inner rail 13a on the upper frame 4 will be described with reference to FIGS. 9 to 12.
In the second link mechanism 30, as in the case of the first link mechanism 20, an upper inner rail 13a having concave grooves 15a on both side surfaces is used, and both side surfaces of the upper inner rail are supported. As shown in FIG. 11, the support arm 31 used is also one in which a pair of levers 31a are integrated in a rotatable connecting shaft portion 31b to the upper frame 4, and these are substantially the first link mechanism. The one having the same structure as in the case of 20 is used.

However, in the second link mechanism 30, the upper inner rail 13a is not directly rotatably connected to the upper inner rail 13a by connecting the lower ends of the plurality of rotatable support arms 31 to the upper frame 4. The tip of the engaging shaft portion 32 protruding from the lower end portion of the pair of levers 31a of the support arm 31 is slidably engaged with the concave groove 15a provided along both side surfaces of the concave groove in the longitudinal direction of the concave groove. Moreover, by connecting the support arms 31 of a certain length located at a plurality of positions including at least both ends in the longitudinal direction of the upper inner rail 13a with a single connecting rod 33 at the engaging shaft portion 32. The second link mechanism 30 is configured.

Further, similarly to the first link mechanism 20, an operation portion 31c is attached to the lower end of the support arm 31 located above the movable frame 9 at the extension position of the net 6, and faces the operation portion. A pressing portion 9a that receives it and presses it toward the frame 3 side is formed on the upper portion of the movable frame 9.
In the case of the second link mechanism 30, as in the case of the first link mechanism 20, the net in the stretched state is adjusted by adjusting the height of the upper surface of the pressing portion 9a in the movable stile 9. The slack of 6 can be adjusted to an appropriate situation.

In the second link mechanism 30 having such a configuration, when the movable stile 9 comes into contact with the receiving frame 3 and the net 6 reaches a completely stretched state, the pressing portion 9a on the upper portion of the movable stile is supported by the support arm. The operation portion 31c at the lower end of 31 is pressed to move the upper inner rail 13a upward in the direction of arrow B in FIG. This is because the upper inner rail 13a is not directly connected to the support arm 31 rotatably connected to the upper frame 4, and the connecting portion with the support arm 31 is slidable. The inner rail moves upward without laterally moving while maintaining the horizontal position. Therefore, the upper inner rail 13a is provided over the stretchable range of the net in the longitudinal direction of the upper frame 4, and the total length of the net 6 is extended. It can be stably supported.

Further, as described above, the lower end of the net 6 in the horizontal pulling roll screen door is guided by a guide fixed to the lower frame 5 of the screen door frame 1 or can be raised and lowered (for example, the lower inner rail 13b). When the movable stile 9 reaches the extension position of the net 6 by its movement operation and moves the upper inner rail 13a in the upper frame 4 upward, the lower end of the net is held at a position where the vertical slack is eliminated by the guide. Will be.
However, when the net 6 is to be stretched more stably without slack, the lower frame 5 of the screen door frame 1 is like the horizontal pulling roll screen door of the second embodiment shown in FIGS. 13 to 15. As for the lower inner rail 13b provided inside, the same ones as the first or second link mechanisms 20, 30 and the like are used in an upside-down state, and both the upper inner rail 13a and the lower inner rail 13b are used as the upper frame 4 and the lower inner rail 13b. It is necessary to hold the lower frame 5 via the link mechanism.

As described above, the second embodiment shown in FIGS. 13 to 15 having such a configuration includes an upper inner rail 13a similar to that of the first embodiment and a first link mechanism 20 for supporting the upper inner rail 13a. At the same time, the lower frame 5 of the screen door frame 1 is provided with the upper inner rail 13a and the first link mechanism 20 provided on the upper frame 4 and the first link mechanism 20 in a vertically symmetrical form. Therefore, in order to avoid duplication of description here, the first link mechanism 20 that supports the upper frame 4 in the figure is attached to the component of the first link mechanism 20 provided in the lower frame 5 in FIGS. 13 and 14. The same reference numerals as those assigned to each part will be attached, and the description thereof will be omitted.

In this way, at the stage of opening and closing the net 6 by operating the movable stile 9, the upper inner rail 13a and the lower inner rail 13b are both moved in the direction in which the net 6 is slack, so that the net 6 has slack. It is highly desirable to facilitate the operation of the net, but it is generally required to eliminate the slack when the net is stretched, so that a special operation for removing the slack when the net is stretched is possible. Although it is necessary, with the above-mentioned horizontal pulling roll screen door, the slack can be automatically eliminated at the final stage of the net installation, so it is possible to keep the net in a tense state at the time of extension without performing any special operation. become.

Further, in general, in the above-mentioned horizontal pulling roll screen door, the take-up box can be arranged on either the left or right side of the screen door frame, and the hanging source of the net can be set on either the left or right side of the screen door frame. At the same time, it is required to be able to make the change. The horizontal pulling roll screen door of the second embodiment of the present invention shown in FIGS. 13 to 15 also solves the above-mentioned problems of improving the operability of opening and closing the net and preventing sagging when the net is extended. Not only that, the hanging source of the net 6 can be set on either the left or right side of the screen door frame 1, and at the same time, the hanging source can be changed.

More specifically, in the horizontal pulling roll screen door of the second embodiment, the take-up box 2 in the screen door frame 1, the receiving frame 3 facing the winding box 2, the upper frame 4 and the lower frame 5 are vertically symmetrical. Not only that, the upper inner rail 13a and the lower inner rail 13b arranged in the upper frame 4 and the lower frame 5 are arranged so as to be symmetrical with each other, and the upper inner rail and the lower inner rail are placed on the upper side. The first or second link mechanisms 20, 30 and the like held in the frame 4 and the lower frame 5 are also arranged vertically symmetrically.
If such a configuration is provided, the take-up box 2 can be arranged on either the left or right side of the screen door frame 1 by installing the net 6 upside down without changing the direction of the upholstery surface. That is, not only can the hanging source be set on either the left or right side, but the hanging source can be changed after installation.

FIG. 16 shows a third embodiment in which the horizontal pulling roll screen door according to the present invention is applied to a double pulling screen door. Basically, one single pulling screen door in the double pulling roll screen door is the other. The movable frame 9 in the single-pull screen door is opened and closed as a receiving frame, and each single-pull screen door is substantially different from that of the first embodiment except that the receiving frame is not fixed. However, since there is no such thing, the description of the first embodiment will be referred to and the duplication of the description will be avoided for the points that are structurally and functionally common to the first embodiment.

The major difference between the screen door of the third embodiment and the screen door of the first embodiment is that the left and right side frames of the screen door frame 1 are both configured by the winding box 2, and these winding boxes include the internal configuration thereof. The nets 6 and 6 on both sides are drawn out from the rotatable winding shaft by lateral pulling of the movable stile 9 and stretched to the left and right in the screen door frame 1. Also, the same as in the case of the first embodiment, and although not shown in FIG. 16, the nets 6 and 6 on both sides are along the upper ends thereof, as in FIG. 2, the engager 12a. Is attached, and by engaging the engaging element with each upper inner rail 13a arranged in the extension region of each net in the upper frame 4 of the screen door frame 1, the net is pulled laterally along the upper frame 4. It is formed so that it can be opened and closed.

Further, in FIG. 16, each of the upper inner rails 13a is described above in the extension region of each of the nets 6 and 6 in the upper frame 4 of the screen door frame 1 with reference to FIGS. 9 to 12. Assuming that the upper inner rail can be moved upward by pressing the upper inner rail in the net extension direction while maintaining the horizontal position via a second link mechanism 30 provided with a plurality of support arms 31 for supporting the upper inner rail. I support it. Then, on the upper part of both movable stiles 9 and 9, when both movable stiles move to their combined positions, the operating portion 31c formed in a part of the link mechanism is pressed toward the combined position side.
