Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retractable architectural closure device which opens and closes a window or door with a closing member such as a retractable insect screen or a retractable blind.
Specifically, along with the window frame A or the door frame, at least a storage case in which a closing member wound up in a roll shape is stored,
By attaching a pair of guide rails arranged in a U-shape from both ends and sliding the draw bar fixed to the drawer end of the closing member along both guide rails, the rectangular shape in the window frame or the door frame A window frame or a door by sliding and sliding both ends of the closing member along the insertion gap formed in the guide rails, or a retractable architectural closing device in which the opening is opened and closed by the closing member. The present invention relates to a retractable architectural closure device in which a rectangular opening in a frame is opened and closed by a closure member.

[0002]

2. Description of the Related Art Conventionally, as this type of retractable architectural closure device, for example, as disclosed in Japanese Patent Application Laid-Open No. 9-78964, a storage case (right A frame is disposed inside the storage case, and a take-up roller having one end fixed to the rotatable shaft is rotatably supported inside the storage case. There is one in which a draw bar (opening / closing bar) fixed to the other side end is moved in the left-right direction and is openably and closably fitted. The outer dimensions of this pulling bar are formed much larger than the drawer opening of the net formed in the storage case, and in the rewinding state of the net where the pulling bar has moved to the storage case side, the pulling bar is in the storage case. From the inner end face toward the rectangular opening in the screen door frame. Further, a runner member having an insertion gap (groove) is attached to the inside of the upper and lower guide rails over the entire opening and closing operation of the draw bar, and the upper and lower ends of the net are slid with respect to this insertion gap. By movably penetrating and engaging a projection larger than the insertion gap protruding from both upper and lower edges of the mesh body, the pulling bar is pulled out of the mesh body away from the storage case, and The projection is prevented from accidentally coming out of the insertion gap of the runner member. On the other hand, in general buildings in recent years, sashes constituting window frames and door frames have been slimmed down in order to increase the amount of light taken indoors by increasing the size of glass plates. In particular, the window frame is connected to the glass frame by a special link mechanism, and when the window is opened, the glass plate has a vertical positional relationship with the window frame, and the outer surface of the glass plate is also easy. Some have a structure that can be wiped.

[0003]

However, in such a conventional retractable architectural closure device, when the closing member is rewound, the pulling bar extends from the inner end face of the storage case toward the rectangular opening. Since the protrusions are so protruded that the draw bars interfere, the opening area of the rectangular opening is substantially reduced. As a result, there is a problem that it is not possible to obtain a large amount of collected light, and it is sometimes impossible to attach the sash to a slim which has been thinned for the purpose. Furthermore, even if the glass plate is positioned vertically with respect to the window frame and a window having a structure in which the outer surface of the glass plate can be easily wiped is adopted, the drawing bar is in the way and the hand is not accessible,
As a result, there is also a problem that the outer surface of the glass plate cannot be wiped. In addition, the insertion gap for preventing inadvertent escape when the closing member is pulled out is particularly narrow when a thin member such as a net is used as the closing member (about 1).
On the other hand, guide rails need to be formed of metal for strength reasons. Since accurate dimensional accuracy cannot be obtained in the case of this metal forming, a runner member formed of a synthetic resin having excellent dimensional accuracy must be mounted in the guide rail, and as a result, the number of parts increases. There is a problem that the structure becomes complicated and the size becomes large, and further, it is necessary to attach the runner member to the guide rail.

[0004] The invention according to claims 1 and 2 of the present invention,
The purpose is to secure a wide opening area of the rectangular opening. The invention according to claim 3 is the invention according to claim 1 or 2
In addition to the object of the invention described in (1), an object of the present invention is to provide a screen door having a wide mounting range.

[0005]

In order to achieve the above-mentioned object, according to the first aspect of the present invention, a drawer opening 1a of a closing member B opened in a storage case 1 is provided. And a space S for storing the draw bar 4 is provided between the storage case 1 and the window frame A or the door frame. According to the second aspect of the present invention, the guide rail 3 is provided with the insertion gap 3a.
And a pair of gap protruding pieces 3c protrude at opposing positions of these assembly parts 3b, respectively. It is characterized in that an insertion gap 3a of a predetermined size is formed between the protruding pieces 3c in an engagement structure. A third aspect of the present invention is characterized in that a configuration in which the closing member B is a net is added to the configuration of the first or second aspect of the invention.

[0006]

According to the first aspect of the present invention, there is provided an outlet 1 for the closing member B.
a is formed so as to be recessed from the inner end surface 1b of the storage case 1,
The storage space S for the pull bar 4 is provided between the storage case 1 and the window frame A or the door frame. The draw bar 4 is stored in the storage space S, does not protrude significantly from the inner end face 1b of the storage case 1 toward the rectangular opening A1, and the installation space for the storage case 1 and the draw bar 4 is reduced. It is. According to the second aspect of the present invention, by assembling the assembly parts 3b of the guide rail 3, the insertion gap 3 having a predetermined dimension is provided between the gap projections 3c.
Since a is formed and the both ends B3 of the closing member B can be directly inserted into the insertion gap 3a, a runner member made of resin molding is not required, and the guide rail 3 is downsized. According to the third aspect of the present invention, a configuration in which the closing member B is a net is added to the configuration of the first or second aspect, so that a miniaturized screen door can be obtained.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. In this embodiment, as shown in FIGS. 1 to 3, along with an aluminum sash constituting a window frame A, a storage case 1 in which a mesh body is stored as a closing member B, and a receiving bar 2 facing in parallel with the storage case 1, A pair of upper and lower guide rails 3 and 3 laid parallel to each other are attached to both ends, and the pull bar 4 fixed to the drawer end B1 of the net B is moved right and left along the two guide rails 3 and 3. By sliding in the direction, the rectangular opening A1 of the window frame A is a rewindable horizontal screen that can be opened and closed by a net B.

As shown in FIG. 1, the storage case 1 is formed to have a hollow rectangular or circular cross section for storing a net B wound in a roll shape. The take-up roller C having the fixed end B2 is rotatably supported.

On the outer peripheral surface of the winding roller C, a winding structure disclosed in Japanese Patent Application Laid-Open No. 9-78964,
Alternatively, the net body B is elastically rewound by a winding structure having a similar structure.

In this embodiment, the storage case 1
However, for example, by combining a plurality of frame members formed continuously in a straight line by extruding a lightweight metal having excellent strength such as aluminum, both end surfaces in the axial direction are formed in a substantially rectangular cross section, As shown in FIG. 3, the openings at both ends are detachably covered with lids 1 ', 1'.

Further, one end B2 of the net body B is directly pushed into the groove C1 formed in the outer peripheral surface of the winding roller C in the axial direction with a holding rope C2 made of an elastic material such as rubber. Thereby, an advantage that the assembling process can be reduced as compared with the one disclosed in Japanese Patent Application Laid-Open No. Hei 9-78964, in which a hard protrusion formed by, for example, sewing on the one end B2 of the mesh body B is pushed. There is.

On the side of the window frame A of the storage case 1, a drawer opening 1a of the net body B unwound from the winding roller C is opened so as to be recessed from the inner end surface 1b of the storage case 1. Between the storage case 1 and the window frame A,
Is provided with a storage space S.

In the case of this embodiment, as shown in FIG. 1, the storage case 1 is formed to have a rectangular cross section slightly larger than the maximum diameter of the winding roller C and the net B wound therearound. Compared with the frame material forming 1b, the frame material forming the outer end face 1c facing the same is formed so as to protrude in an L-shaped cross section toward the window frame A side, and the window frame side end face 1d of the frame material is formed. It is attached in contact with window frame A.

As a result, a drawer port 1a facing the receiving bar 2 is formed in a concave shape from the inner end face 1b of the storage case 1, and the drawer port 1a, an aluminum sash forming the window frame A, and a facing face thereof. With the frame side surface 1e of the storage case 1, a storage space S which is slightly wider than the front-rear depth dimension of the draw bar 4 and can be taken in and out is formed.

Further, a winding portion 1f, which is in contact with the net B unwound from the winding roller C, is formed at the leading end of the frame material forming the frame side surface 1e of the storage case 1 so as to be bent. The net body B can be easily rewound and wound around C.

On the other hand, as shown in FIGS. 1 and 3, each of the guide rails 3 has an insertion gap 3a for allowing the upper and lower ends B3 of the net B to be slidably inserted in the upper central portion thereof in the axial direction. Are formed in a plurality of sections and are divided in the axial direction with the insertion gap 3a as a boundary, and a pair of gap projections 3c, 3c are provided at opposing positions of the assembly parts 3b. In the assembled state, an insertion gap 3a having a predetermined dimension (about 1 mm) is defined between the projections 3c, 3c.

In the case of this embodiment, two opposing assembly parts 3b, 3b formed continuously by extruding a lightweight metal having high strength such as aluminum, for example.
Consists of One of these assembly parts 3b, 3b is formed to have a substantially I-shaped cross-section, and the other is formed to have a substantially L-shaped cross-section.
By continuously connecting the engaging pieces 3b 'to be engaged with the shaped assembly parts 3b, the two assembled parts 3b, 3b are assembled in a substantially U-shaped cross section.

Further, the projections 3c, 3c and the insertion gap 3a of the assembly parts 3b, 3b define a projection insertion space 3d on the upper and lower sides between the assembly parts 3b, 3b. In the insertion space 3d, a projection B4 larger than the insertion gap 3a integrally projecting, for example, by welding, on both upper and lower edges of the mesh body B is inserted.
Is engaged with the edge of the insertion gap 3a,
When the net B is pulled out of the storage case 1, the projection B4 of the net B is prevented from accidentally coming out of the insertion gap 3a.

Further, fitting claws 3e, 3e are projected from upper and lower inner ends between the two assembled parts 3b, 3b to form a sliding space 3f between the fitting projections 3c, 3c. Between the fitting claws 3e, 3e and in the sliding space 3f, sliding members 4a continuously connected to the upper and lower ends of the draw bar 4 so as to sandwich the net B are slidably engaged with each other. The sliding member 4a is formed of, for example, a synthetic resin having excellent slipperiness in an E-shaped cross section.

In the case of the present embodiment, the inner corners 3g of the sliding space 3f are rounded so that the sliding bar 4
The rope can be moved smoothly even if it is pulled out diagonally. Furthermore, this smooth rope movement is not limited only to the inner corners 3g of the sliding space 3f described above. Instead, the corners of the sliding member 4a may be rounded, or the inner corners 3g. Both the corners of the sliding member 4a may be rounded.

Next, the operation of the retractable architectural closure device will be described. First, in a rewinding state of the closing member B in which the pulling bar 4 shown in FIG. 1 is moved to the storage case 1 side and the rectangular opening A1 is opened, the pulling bar 4 is stored in the storage space S. It does not project significantly from the inner end surface 1b of the case 1 toward the rectangular opening A1.

Thereby, the installation space for the storage case 1 and the pull bar 4 is reduced in the left-right direction. As a result, since the draw bar 4 does not interfere, the opening area of the rectangular opening A1 can be secured wide in the left-right direction. Therefore, the amount of collected light can be increased as much as the pulling bar 4 does not interfere, and it can be attached to a slim, recent sash.

Further, when the window W is opened by connecting the window frame A and the frame F of the glass plate G with a special link mechanism L, the glass plate G has a vertical positional relationship with respect to the window frame A. When the window W is employed, the draw bar 4 does not become an obstacle, a space for a hand can be secured, and the outer surface G1 of the glass plate G can be easily wiped.

Also, the assembly parts 3b, 3 of the guide rail 3
b are engaged with each other, and these two projections 3c,
An insertion gap 3a having a predetermined dimension is defined between the sections 3c, and both ends B3 of the closing member B can be directly inserted into the insertion gap 3a. This eliminates the need for a resin-formed runner member as disclosed in Japanese Patent Application Laid-Open No. 9-78964. In addition, both the front and rear depth dimensions are reduced to about 4/5 or less.

As a result, since the guide rail 3 does not interfere, the opening area of the rectangular opening A1 can be secured widely in the vertical direction. Therefore, the amount of light to be collected can be increased as much as the guide rail 3 does not interfere, and it can be attached to a slim, modern sash. Furthermore, guide rail 3
Since there is no need to install a resin-formed runner member in the inside, the number of working steps can be reduced, the assembly time can be shortened, and the manufacturing cost can be reduced.

On the other hand, those shown in FIGS.
FIG. 5 shows another embodiment of the present invention.
FIG. 4A shows a modification of the draw bar 4.
FIGS. 4 (b) to 4 (d) show modified examples of the storage case 1 and the pull bar 4, and other configurations are shown in FIGS.
This is the same as the embodiment shown in FIG.

In FIG. 4 (a), the width of the cross bar 4 is made shorter than that shown in FIG. In the unwound state of the stored net B, the leading end position 4
b is arranged so as not to project from the inner end face 1b of the storage case 1 toward the rectangular opening A1 at all. As a result, FIG.
1A has an advantage that the installation space for the storage case 1 and the pull bar 4 can be further reduced in the left-right direction as compared with the one shown in FIG.

FIG. 4 (b) corresponds to FIGS. 1 and 4 (a).
By making the front and rear depths of the draw bar 4 thinner than those shown in FIG. 4 and shortening the length of the frame material constituting the inner end face 1b of the storage case 1 toward the window frame A, The front and rear depth dimension of the space S is made narrow. As a result, the one shown in FIG.
Compared to the case shown in FIG.
Is further reduced in the front-rear direction.

In FIG. 4C, the storage case 1 is formed in a square cross section, and a drawer 1a of the net B is recessed from the inner end surface 1b at the corner of the window frame side. The draw bar 4 is formed in a triangular cross section to be fitted with the draw bar 4, and a space S for storing the draw bar 4 is formed between the drawer opening 1 a and the window frame A, thereby forming the draw bar 4. In the rewinding state of the net B moved to the storage case 1 side most,
The distal end position 4b is arranged so as not to project from the inner end surface 1b of the storage case 1 toward the rectangular opening A1 at all.
As a result, the one shown in FIG.
The storage case 1 and the pull bar 4 are different from those shown in FIG.
There is an advantage that the installation space can be further reduced in the front-rear direction and the left-right direction.

In FIG. 4D, the storage case 1 is formed to have a square cross section, and the frame material forming the inner end surface 1b is as follows.
At least the outer end surface 1c is formed so as to be separable from the frame material, and the inner end surface 1b is formed by integrally connecting the draw bar 4 to the window frame side of the frame material forming the inner end surface 1b.
The drawer opening 1a is recessed and opened, and a space S for storing the drawer bar 4 is defined between the drawer opening 1a and the window frame A. As a result, in FIG. 4D, the installation space of the storage case 1 and the pull bar 4 is further reduced in the front-rear direction and the left-right direction as compared with those shown in FIGS. 1 and 4A and 4B. There is an advantage that can be made.

In the illustrated example, the frame material of the indoor side end surface 1g is added to the frame material of the indoor end surface 1b where the above-mentioned pulling bar 4 is continuously provided.
This figure shows a case in which the handle portion 4a is integrated into a character shape and is slid together with the draw bar 4, and a handle portion 4a is provided at these corners to make it easy for a user's finger or the like to be caught. But,
The frame material of the indoor side end surface 1g is separated from the frame material of the inner end surface 1b so that the net B wound up by the winding roller C is not exposed when the net B is pulled out. The frame material of the inner end face 1b integrated with the frame material of 1c may be divided so that only the window frame side is slid together with the pull bar 4.

4 (a) to 4 (c) show the net B in which the pull bar 4 is moved to the storage case 1 side most.
In the unwound state, the distal end position 4b is arranged so as not to protrude from the inner end face 1b of the storage case 1 toward the rectangular opening A1 at all. In order to prevent this, the handle portion is partially protruded at an appropriate height above and below the tip position 4b, or the lock is released with the pushing operation of the tip position 4b so that the handle can be pulled out. The structure may be such that

The guide rail 3 shown in FIG.
Shows a modified example composed of three or more opposed assembly parts 3b divided in the axial direction with the insertion gap 3a as a boundary,
Other configurations are the same as those of the embodiment shown in FIGS. 1 to 3 or FIGS. 4 (a) to 4 (d). The illustrated example shows a case where the guide rail 3 is composed of three assembly parts 3b, 3b, 3b ", and the assembly parts 3b, 3b arranged at both ends thereof.
Is formed into a substantially symmetrical cross section with a line symmetry, and an assembly part 3b ″ located between the two is formed into a substantially H shape cross section, and is engaged with the assembly parts 3b, 3b at both ends, respectively. The parts 3b, 3b, 3b "are assembled in a substantially U-shaped cross section.

As a result, the one shown in FIG. 5 has an increased engagement strength of the three assembled parts 3b, 3b, 3b ″ when assembled in a substantially U-shaped cross section as compared with the one shown in FIG. Even if an external force acts on the assembly parts 3b, 3b at both ends, the gap projections 3c, 3c protruding therefrom are formed.
Are not displaced, and there is an advantage that the insertion gap 3a having a predetermined dimension (about 1 mm) defined between them is hard to change.

In the above-described embodiment, the case where the rectangular opening A1 of the window frame A is a rewindable horizontal screen door which can be opened and closed by the mesh body B has been described, but the present invention is not limited to this and is not shown. Is window frame A

May be. Further, the closing member B is not limited to a net such as a wind-up insect screen, but may be anything as long as it can be wound up such as a wind-up blind.

[0036]

As described above, according to the first aspect of the present invention, the drawer opening 1a of the closing member B is formed so as to be recessed from the inner end surface 1b of the storage case 1. A space S for storing the pull bar 4 is provided between the window frame A and the door frame A, so that when the closing member B, which has moved the pull bar 4 most to the storage case 1 side, is unwound, the pull bar 4 Is stored in the storage space S and does not protrude significantly from the inner end face 1b of the storage case 1 toward the rectangular opening A1,
Since the installation space for the storage case 1 and the pull bar 4 is reduced, a large opening area of the rectangular opening A1 can be secured. Therefore, as compared with the conventional one in which the opening area of the rectangular opening is substantially narrowed by the draw bar, it is possible to obtain a large amount of collected light, and it is possible to attach it to a slim sash in recent years. Further, when a window having a structure in which the glass plate is perpendicular to the window frame is employed, a space for a hand can be secured and the outer surface of the glass plate can be easily wiped.

According to a second aspect of the present invention, in addition to the effects of the first aspect of the present invention, by assembling the assembly parts 3b of the guide rail 3 with each other, a predetermined dimension is provided between the two projections 3c. Is formed, and both ends B3 of the closing member B can be directly inserted into the insertion gap 3a, so that a resin-formed runner member is not required, and the size of the guide rail 3 is reduced. In addition, a large opening area of the rectangular opening A1 can be secured. Therefore, compared to the conventional guide rail having a large guide rail, the amount of light to be collected can be increased, and it can be mounted on a slim, recent sash. Furthermore, as compared with the conventional one which requires the labor of mounting a resin-formed runner member having an insertion gap in a metal guide rail for strength reasons, the number of working steps can be reduced and the assembly time can be shortened. In addition, the manufacturing cost can be reduced.

According to the third aspect of the present invention, in addition to the effects of the first or second aspect, a miniaturized screen door can be obtained.
A screen door with a wider mounting range can be provided.
