1 SASH FOR OPENING

BACKGROUND OF THE INVENTION

2331541 1. FIELD OF THE INVENTION

This invention relates to an extrusion molded sash of an opening, which is provided in an opening formed on a wall of a building and used for structuring a window, a door and so on. Particularly, this invention uses an extrusion molded member, as a fi=e member of a sash, which is formed by means of extrusion molding with metal materials, such as aluminum alloy, or non-metal materials, such as synthetic resin.

2. DESCRIPTION OF THE RELATED ART

Openings are formed on walls of a building for the various purposes. For example, a door is formed for letting people and loads come and go, and a window is formed for letting light or fresh air in.

A window sash or a door sash is attached into the opening. The above sash for the opening is composed of frame members which are fixed along the inner periphery or sides of the opening and a panel portion which is supported in the frame member.

Panel portion The panel portion is appropriately selected in accordance to a required function for the opening. For example, a swing door, a sliding door or the like is used in openably on the panel portion of the door sash for an entrance. An openable transparent glass door is generally used for the panel portion of the window. A frosted glass is used for shielding visibility. A fixed glass door is used when the window is not needed to be opened. Additionally, a louver instead of the glass door is fitted when fresh air is needed to be changed all the time.

On occasion the plastic face member fitted into the door is used as an 2 alternative to the glass plate. Alternatively, not only the completely transparent glass but also a patterned glass, a frosted glass or the like can be used.

The panel portions can be used in combination. For example, a 5 section adjacent to the openable glass door is attached with the louver, and the upper section of the door sash is attached with the glass door and the lower section is used as the door.

Frame Concerning the frame of the sash for the opening, an extrusion molded member made of aluminum alloy has been generally used lately. A conventional wooden frame is insufficient in durability, and in addition, further processes, such as fitting up a rail for a sliding door, are required. A metal member, such as iron, is insufficient in the corrosion resistance and weight. On the other hand, the aluminum alloy frame is lighter in weight and has a high corrosion resistance. Additionally, a rail and the like can be molded together with the frame by the extrusion molding, thus resulting in smaller production cost.

The small-sized frame is assembled to be a rectangular shaped frame with a predetermined size at a factory in advance. In the large-sized frame, an elongated member for forming each side of the frame can be cut to a length corresponding to a size of an opening at the site of construction, and the cut member is fixed into the inner peripheral surface of the opening. Normally, a sash is attached into one opening and the sizes of the frames of the sash approximately correspond to the size of the opening.

Attachment of the sash When the sash for the opening, which is composed of the frame and the panel portion, is attached into the opening, in ordinary assembling steps, the frame is initially attached onto the inner peripheral surface of the opening, and then the panel portion is supported by the attached frame.

Where the inner periphery of the. opening are made of wood, the 3 attachment of the sash to the opening is carried out by passing an attaching pin, such as a screw and a nail, from the inner peripheral surface of the frame toward the inner peripheral surface of the opening. Where the inner peripheral surface of the opening is made of brittle materials, such as a wall made of blocks and a brick wall, a supporting base is fixed on the inner peripheral surface of the opening with an anchor bolt or the like in advance, and then the frame is fixed to the supporting base.

The following steps are applied for supporting the panel portion into the frame. Where the panel portion is openable, the panel portion is coupled with the frame by a hinge or the like. Where the panel portion is fixed not to open, the panel portion is screwed onto the frame in many cases, and can be partially hooked and screwed in the final step, for example.

Local character of the sash On occasion the structure of the sash for the opening is adapted for conditions of countries or regions. For example, a cold-proof construction, such as a double-glass window, is required in a fiigid zone, and a ceaseless opened construction, such as a louver, is heavily used in regions of a hot, moist climate. The design of the sash is also adapted for customs of countries or regions.

For example, in Southeast Asia, such as the Republic of Indonesia and Malaysia, ornamental sculpture by cylinderical surface is continuously formed along the frame or the like of the sash. Conventionally, the ornamental sculptured face is formed by performing a cutting process on a surface of a wooden window frame or the like to carve concavities or convexities which has an arc-shape cross-sectional face.

Problems In the aluminum alloy made sash for the opening which has been prevalent lately, however, the sides of the frame or the panel portions (e.g., the door frame) are formed to be flat, therefore, demand for the ornamental sculpture in Southeast Asia is not sufficiently satisfied.

4 Screwing is necessary to fix the panel portion into the frame, so that efficiency of construction is not improved by an extra process for screwing.

The structure of an attaching portion of the frame is sometimes changed depending upon a way in which the frame is attached into the opening by using the screw or the nail or using the supporting base as described above, so that two types of the frames are needed for one window sash, thus complication of production and the control of parts.

And then, as one sash for the opening is applied for each of an opening as described above, it is needed to apply a large sash for a large opening, thsu resulting in inconvenience in transport and construction.

ObL(Icts It is an object of the present invention to provide a sash for an opening having an ornamental sculpture to satisfy demand in Southeast Asia at small cost and with simplification.

It is another object of the present invention to provide a sash for an opening which is efficiently produced by easily attaching a panel portion into a frame.

It is still another object of the present invention to provide a sash for an opening, in which a frame is one type even when different ways are applied to attach the frame into an opening.

It is yet another object of the present invention to provide a sash for an opening, in which transport and construction for even a large opening are conveniently carried out.

SUMMARY OF THE INVENTION

The present invention is a sash for an opening comprising a frame attached into an opening of a building and a panel portion covering the opening by being supported in the frame, characterized in that the peripheral portion of the panel portion and/or the frame are assembled with extrusion- molded members; and the extrusion-molded member has thereon a cylindrical ornamented surface, continuous in the longitudinal direction of the extrusion-molded member and having an arc-shaped cross-sectional face in the direction intersecting the continuing direction.

In this way, the cylindrical ornamented surface can be easily formed by continuously extrusion-molding the aforementioned sectional arc-shaped portion. As materials for the extrusion-molded member, metal, synthetic resin or the like can be used, thereby achieving a sash for an opening having the ornamented surface to satisfy demand in Southeast Asia, at low production costs and with ease.

In the present invention, it is advisable that a portion of the extrusionmolded member on which the cylindrical ornamented surface is formed has a concentric arc-shape on the front and rear faces and a uniform thickness.

Thus, the thickness of the extrusion-molded members is uniform, thereby improving the formability and decrease of materials.

In the present invention, it is desirable that the cylindrical ornamented surfaces are consecutively and parallel formed, so that the adjacent cylindrical ornamented surfaces respectively have concavity in the opposite direction.

In this way, decoration scrupulous in the ornamented surface required in Southeast Asia is successfully presented, thereby being superior in design.

In the present invention, it is advisable that the extrusion-molded member is made of aluminum alloy.

In this way, the fundamental performance as the sash for the opening can be sufficiently exerted.

In the present invention, it is advisable that a part of the panel portion is a fixed window body; and an elastic concavoconvex engaging means is 6 formed between the fixed window body and the frame, in which the elastic concavoconvex engaging means is formed in a portion selected from the frame and the fixed window body, and having a one-way hook made of elastic materials, in which the one-way hook allows movement when a non- selected portion of the frame and the fixed window body is moved in a predetermined inserting direction, and engages the non-selected portion when the non-selected portion is moved in the opposite direction to the inserting direction.

In this way, the attachment of the fixed window body into the fi-ame can be smoothly carried out, thereby improving efficiency of workability.

In the present invention, it is desirable that the one-way hook has a guide face in which the end of the guide face slopes in the inserting direction.

For this point, the process, that the one-way hook or receiver is elastically deformed in the direction intersecting the inserting direction and engaged, can be easily carried out by the sloped guide face.

In the present invention, it is advisable that the inserting direction is a direction intersecting the opening; a section of the frame in which the fixed window body is attached is provided with a stopper for abutting to the vicinity of the face orienting toward the not-inserting direction of the fixed window body when the fixed window body is moved in the inserting direction; the one-way hook is placed closer to the side to which the fixed window body is inserted than the stopper; and the fixed window body has a part of which one face is abutted to the stopper and the other face is pressed in the inserting direction by the one-way hook.

In this way, the fixed window body can be smoothly attached from one side of the frame, and additionally, the fixed window body can be stably supported by being elastically pressed to the stopper.

Incidentally, the inserting direction is the direction intersecting, the opening as described above, that is to say, it is, for example, a direction passing from the inside of room through the opening to the outside of room, 7 in other words, it is the thickness direction of the fixed window body.

In the present invention, it is desirable that the frame has a main face portion approximately parallel to the inner peripheral surface of the opening; the main face portion is formed with a penetrating portion for passing an attaching pin extending toward the inner peripheral surface of the opening; and the frame has an engaging portion, having the elastic concavoconvex engagement with a support base fixed on the inner peripheral surface configuring the opening, on the outer surface of the frame which opposes to the inner pefipheral surface configuring the opening.

In this way, even when various methods for attaching the frame into the opening are applied, the same frame in any methods is used.

In the present invention, it is desirable that the main face portion has stand portions, extending in the direction approximately intersecting the main face portion, on both the side ends of the main face portion; and the engaging portion is formed in the vicinity of the end of the stand portion.

In this way, the main face portion can be maintained to have a space from the inner peripheral surface of the opening by the stand portions formed at both end of the main face portion. In addition, the frame has the approximate C-shape in section formed by the main face portion_ and the two stand portions, thereby obtaining strength.

In the present invention, it is advisable that the engaging portion has a step portion having a tread face parallel to the main face portion; and the support base has a one-way hook engaging the step portion.

In this way, the sash using the support base can be simply and smoothly attached.

In the present invention, it is advisable that the frame is connected with a ribbon window mullion on the outer face thereof which opposes to the inner peripheral surface configuring of the opening; the frame has an 8 engaging portion, having the elastic concavoconvex engagement with the ribbon window mullion, on the outer face of the frame; and the ribbon window mullion has an engaged portion, having the elastic concavoconvex engagement with the frame, to orient in two directions.

In this way, more than two sashes for the opening can be coupled through the ribbon window mullion. In addition, with the use of plural sashes for the opening, small sashes are sufficiently used for even a large opening, thereby resolving the inconvenience in transport and construction.

In the present invention, it is desirable that the engaging portion for ribbon window has a step portion having a tread face parallel to the main face portion; and the support base has a one-way hook engaging the step portion.

The above structure allows the sash to easily and smoothly couple to 15 the ribbon window mullion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODUVIENT(S)

First Embodiment The first embodiment according to the present invention is shown in Fig. I to Fig. 3.

In Fig. 1, a door sash 10 is attached into an opening 2 that is formed on a wall I of a building or the like.

The door sash 10 has a frame I I fixed on the inner peripheral surface of the opening 2. The frame I I is composed of stile members I I I and 112, a top rail member 113 and a horizontally intermediate rail member 114. The members I I I to 114 are extrusion-molded members that is made of aluminum alloy.

Each of the stile members I I I and 112 is vertically extended and fixed on each of inner vertical sides of the opening 2. The top rail member 113 is coupled to the top ends of the stile members I I I and 112 at the right and left ends thereof, and fixed on the horizontal top side of the opening 2.

The intermediate rail member 114 is coupled to the intermediate portions of the stile members I I I and 112 at the ends thereof, and horizontally bridged towards a predetermined lower position from the top rail member 113.

As also shown in Fig. 2 and Fig. 3, a fixed-window panel 12 as a panel portion is fitted into the upper division over the intermediate rail member 114 in the frame 11, and a door panel 13 as the panel portion is supported into the lower division under the intermediate rail member 114.

Fixed-window panel The fixed-widow Panel 12 is a transparent glass plate and fixed to the frame 11. On the inner faces of the stile members 111 and 112, the top rail member 113 and the intermediate rail member 114 which surround the fixed window panel 12, supporting members 121 and 122 are formed to fixedly pinch the edge portions of the fixed-widow panel 12.

The supporting member 121, facing the outside of a room, is formed continuously from each of the frame members 111 to 114. A packing member 123, such as rubber, having cushioning properties and being waterproof, is fitted on the edge of the supporting member 121 between the supporting member 121 and the fixed-window panel 12, so that the edge of the supporting member 121 is pressured through the packing member 123 onto the fixed-window panel 12.

The supporting member 122, facing the inside of a room, is an independent member from each of the frame members 111 to 114, in which the portions along each of the frame members 111 to 114 are mutually coupled to form a quadrangular frame. A packing member 124, such as rubber having cushioning properties and water-proof, is fitted on the edge of the supporting member 122 between the supporting member 122 and the fixed-widow panel 12. The fi-ame-shaped supporting member 122 is pressured through the packing member 124 onto the fixed-window panel 12 by being inserted from the inside of a room into each inside of the frame members 111 to 114. As a result, the fixed-window panel 12 is fixedly pinched through the packing members 123 and 124 between the supporting members 121 and 122.

In order to maintain a state that the frame-shaped supporting member 122, inserted in the inside of each of the frame members 111 to 114, fixedly sandwiches the fixed-window panel 12 with the supporting member 12 1, an elastic concavoconvex engaging means is provided between the supporting member 122 and each of the frame members 111 to 114.

An end 125 of the supporting member 122, which is extended toward the fixed-window panel 12, is formed in a wedge shape. A connecting member 126 made of elastic materials is intermittently screwed to each of the frame members 111 to 114 with screws. An end 127 of the connecting member 126 extends toward the supporting member 122 and has a wedge shape. Consequently, when the supporting member 122 is inserted from the inside of a room, the wedge-shapes of the ends of 125 and 127 guide the supporting member 122. The connecting member 126 is elastically 12 deformed in the direction intersecting the inserting direction, and, a step formed on a base of the wedge-shaped end 127 is engaged with a step formed on a base of the wedge-shaped end 125 of the supporting member 122, with the result that the supporting member 122 and the connecting member 126 are fixedly combined by the engagement of the wedge-shaped ends 127 and 125.

The supporting member 121 is provided with an arc-shaped crosssectional face in the middle portion between each of the frame members I I I to 114 and the edge of the supporting member 121 which is fitted thereon with the packing member 123. The sectional arc-shaped portion is a concentric circle shape on the front face confronting the outside of a room and the rear face confronting the inside and has a uniform thickness. The supporting member 121 including the sectional arc-shaped portion is formed together with the frame members I I I to 114 by extrusion molding. The sectional arc-shaped portion continues along the longitudinal direction of each of the frame members I I I to 114, so that a cylindrical ornamented surface 141 is visible to surround the fixed- window panel 12 from the outside of a room.

The supporting member 122 is formed to have two sectional arc shapes in the middle portion between each of the frame members I I I to 114 and the edge of the supporting member 121 which is fitted thereon with the packing member 123. One sectional arc-shaped portion, which is formed close to each of the frame members I I I to 114, is concave when viewed from the outside of a room. The other sectional arc-shaped portion, which is formed close to the packing member 124, is convex. In other words, the concavity and convexity of the two sectional arc-shaped portion are opposite with each other. Each sectional arc-shaped portion is a concentric circle shape on the front face confronting the outside of a room and the rear face confronting the inside, so that the thickness is uniform. The supporting member 121 including the sectional arc-shaped portions is formed together with the frame members I I I to 114 by extrusion molding. The sectional arcshaped portions continue along the longitudinal direction of each of the 13 frame members 111 to 114, with the result that two cylindrical omamented surfaces 142 and 143 are visible to surround the fixed-window panel 12 from the outside of a room.

Door panel As shown in Fig. 1, a door panel 13 has a door knob 131 on one vertical side and is connected with the frame I I through hinges (not shown) on the other vertical side so as to be opened by pivoting on the hinge side as an axis. The door panel 13 itself is a general door plate member made of wood or metal.

On each inner faces of the stile members I I I and 112 and the intermediate rail member 114 which surround the door panel 13, an abutting member 132 is formed in order to abut the edge portion of the door panel 13 from the outside of a room.

The abutting member 132 is formed continuously from each of the frame members I 11, 112 and 114. A door stopper member 13 3 made of rubber or the like having cushioning properties and water-proof is fitted on the end of the abutting member 132, which confront to the door panel 13, so that the end of the abutting member 132 is abutted through the door stopper member 133 to the door panel 13.

The abutting member 132 is provided with a sectional arc shape in the middle portion between each of the fi-ame members I 11, 112 and 114 and the edge of the abutting member 132 which is fitted thereon with the door stopper member 133. The sectional arc-shaped portion is a concentric circle shape both on the front face confronting the outside of a room and the rear face confronting the inside, so that the thickness is uniform. The abutting member 132 including the sectional arc-shaped portion is formed together with the frame members I 11, 112 and 114 by extrusion molding. The sectional arc-shaped portion continues along each longitudinal direction of the frame members I H, 112 and 114, so that a cylindrical ornamented surface 144 is visible to surround the door panel 13 from the outside of a room.

14 Attachment of the frame The intermediate rail member 114 of the frame 11 has a rectangular shaped cross-sectional face. The top rail member 113 and the stile members 111 and 112, which are attached on the inner peripheral surface of the opening, each have an approximately C-shape in section.

The top rail member 113 and the stile members 111 and 112 respectively have a main face portion 151 and a pair of stand portions 152 which form the sectional C-shape. Note that the following description is as to the stile member 112 shown in the lower part of Fig. 3, but the stile member 111 and the top rail member 113 are similar to the stile member 112.

One face of the main face portion 151 confronts the fixed-window panel 12 or the door panel 13, and the other face confronts the inner peripheral surface of the opening with a predetermined space. The stand portions 152 stands on the side ends of the main face portion 151 in the intersecting direction at right angles and extends toward the inner peripheral surface of the opening. The ends of the pair of stand portions 152 are bent twice to approach each other so as to be a cranked-shape, with the result that a step portion 153 having a tread face opposite the main face portion 151 is formed in the stand portion 152.

In order to fix the stile members I I I and 112 and the top rail member 113, a support base 154 is placed on the inner peripheral surface of the opening 2. The support base 154 is formed by using an extrusion molded member made of aluminum alloy, which can be placed along the stile members I I I and 112 and the top rail member 113 as a continuous member, and alternatively can be cut and placed at predetermined spaced intervals. The support base 154 is secured on the inner peripheral surface of the opening 2 with an anchor bolt 155. As the anchor bolt 155, for example, a bolt that is expanded inside by opening a hole and fastening, and a bolt that is called an anchor for concrete, a fisher plug (a metallic or plastic tubular utensil for screwing a screw on a concrete wall or the like, which is driven into a hole opened on the concrete wall or the like and passed through therein and engaged with the screw or the like) or the like can be used.

The support base 154 has wedge-shaped engaging projections 156 along the side ends thereof. Concerning the engaging projection 156, each of the stile members 111 and 112 and the top rail member 113 is fitted onto the support base 154, and the stand portions 152 of the both sides of the frame member are pressured along outside the engaging projections 156, thereby the engaging projections 156 are elastically deformed inward by the wedge shape, and then a step of a base of the wedge shape is engaged with each step portion 153 of the stand portions 152. By the above engagement, the stile members 111 and 112 and the top rail member 113 are engaged with the support base 154 and fixed on the inner peripheral surface of the opening 2.

It should be mentioned that a penetrating portion 157 is formed at the central portion of the main face portion 151 to be thicker than the periphery of the main face portion 15 1. The frame member can be directly fixed onto the inner peripheral surface of the opening 2 by opening a hole on the penetrating portion 157 and being screwed or nailed down.

According to the first embodiment described thus far, the following effects are listed.

Cylindrical ornamented surface With the sectional arc-shaped portions formed on the supporting members 121 and 122 and the abutting member 132 which surround the fixed-window panel 12 and the door panel 13, the cylindrical ornamented surfaces 141, 142, 143 and 144 can be continuously formed on the margin of the fixed-window panel 12 and the margin of the door panel 13. The supporting member 121 and the abutting member 132 are combinedly formed together with each of the frame members I I I to 114 by the continuous extrusion molding, and the independent supporting member 122 is also formed by the continuous extrusion molding. Thereby achieving the sash for the opening, having the ornamented surface can be achieved to16 satisfy demand in Southeast Asia, at low cost and with eases.

In each of the sectional arc-shaped portions of the supporting members 121 and 122 and the abutting member 132, which are formed thereon with the cylindrical ornamented surfaces 141, 142, 143 and 144, the rear face is a concentric arc-shape with the front face, so that the thickness is uniform, thereby allowing the extrusion-molded members to have a uniform thickness at each portions so that the formability can be improved and materials can be decreased.

Concerning the supporting member 122, the cylindrical ornamented surfaces 142 and 143 are consecutively and parallel formed, so that the adjacent cylindrical ornamented surfaces respectively have concavity in the opposite direction, thereby successfully presenting decoration scrupulous in the ornamented surface required in Southeast Asia, and being superior in design.

Attachment of the fixed window bo The fixed-window panel 12 placed in the upper division is defined as a fixed window body, and the fixed-window panel 12 is clamped between the supporting members 121 and 122 and is fixed to the supporting member 122 by the elastic concavoconvex engagement with the connecting member 126 as a one-way hook, so that the fixed-window panel 12 can be smoothly attached into the frame 11, thereby enhancing the efficiency of manufacturing.

The connecting member 126 as the one-way hook is formed in a wedged-shape having a guide face with sloping end, thereby having an easy process that the connecting member 126 is elastically deformed toward the side for the inserted direction of the supporting member 122 and engaged with the supporting member 122 when the fixed-window panel 12 is attached into the frame 11.

Attachment to the opening The stile members 111 and 112 and the top rail member 113 each 17 have the main face portion 151 approximately parallel to the inner peripheral surface of the opening 2. The penetrating portion 157 is provided on the main face portion 151 for passing an attaching pin extended toward the inner peripheral surface of the opening, and the step portion 153 is formed at both sides of the main face portion 151 as an engaging portion for making the elastic concavoconvex engagement with the support base 154 secured on the inner peripheral surface of the opening, thereby using the same frame even when the attachment is directly carried out with the attaching pin or the like or carried out with the support base 154.

Concerning the stile members 111 and 112 and the top rail member 113, the stand portion 152 is formed at each side end of the main face portion 151 to extend in the intersecting direction at right angles to the main face portion 151, and additionally, the step portion 153 as the engaging portion is formed in the vicinity of the end of the stand portion 152, so that the main face portion 151 can be maintained to have a space from the inner peripheral surface of the opening for the stand portions 152 formed at both end of the main face portion 15 1, and additionally, the frame members 111, 112 and 113 each have an approximately C-shaped cross-sectional face formed by the main face portion 151 and the stand portions 152 of both side ends of the main face portion 15 1, thereby effecting the strength.

The engaging portion formed in the main face portion 151 is defined as the step portion 153 having the tread face parallel to the main face portion 151. In addition, the support base 154 has the wedge-shaped engaging projection 156, as a one-way hook capable of engaging with the step portion 153, at the end of the base 154. Thereby easily and simply attaching the frame even when the support base 154 is used.

Others The extrusion-molded members assembling the door-sash 10 including the frame members I I I to 114 and the supporting member 122 is made of aluminum alloy, thereby sufficiently exerting the fundamental performance as the door-sash 10.

18 The door panel 13 opens inwardly, that is, to a room in the embodiment, and alternatively the door-sash 10 can be structured to open the door panel 13 outwardly, that is, away from a room by attaching the doorsash 10 into the opening 2 to reverse the front and the back of the overall door-sash 10.

Second Embodiment Fig. 4 to Fig. 7 show the second embodiment according to the present invention.

In Fig. 4, a window-sash 20 is fitted in the opening 2 which is formed on the wall 1 of the building or the like.

The window-sash 20 has a frame 21 fixed on the inner peripheral surface of the opening 2. The frame 21 has stile members 211 and 212, a top rail member 213 and an intermediate rail member 214. Each of the frame members 211 to 214 has the same structures, including the details, as each of the frame members 111 to 114 described in the first embodiment, so that the description is omitted.

As shown in Fig. 5 and Fig. 6, a fixed-window panel 22 as the panel portion is fitted into the upper division of the intermediate rail member 214 in the frame 21. As shown in Fig. 5 and Fig. 7, an openable window panel 23 as the panel portion is supported in the lower division of the intermediate rail member 214.

Fixed-window panel The fixed-window panel 22 has a transparent glass plate 220, a latticed member 221 oriented toward the inside and outside of a room supported along each of the surfaces of the glass plate 220, and an inner frame member 222 fitted onto the margin of the glass plate 220, through which the fixed-window panel 22 is fitted to the frame 2 1.

The latticed member 221 is made of aluminum alloy like the frame 2 1, which is formed by connecting the alloy-made extruded elongated-material 19 to intersect in the horizontal and vertical directions. The crosssectional shape of the latticed member 221 is a shape that an arc-shaped portions are coupled with each side of an approximately C-shaped portion placed between the arc-shaped portions. The latticed member 221 is adhered to the glass plate 220 by sticking a double-sided adhesive tape (not shown) on the C-shaped portion and sticking the other side of the double-side adhesive tape on the glass plate 220. For the adhered state, the end of the arc-shaped portion is in close contact with the glass plate 220 so that the above doublesided adhesive tape can be hidden. It should be mentioned that a cylindrical omamented surface 241 is formed on both sides of the latticed member 221 by using the arc-shaped portion of the latticed member 22 1. The arc- shaped member has an outward convexity, the inner and outer faces being a concentric circle shape, so that the thickness is uniform.

Fig. 8 to Fig. 12 show structure of the intersecting connection of the latticed member 22 1. As shown in Fig. 8 to Fig. 10, at the intersection of the latticed member 221, the arc-shaped portions which are positioned along both sides of a vertical member 2211 are cut, but the C-shaped portion placed between the arc-shaped portions is continued. A lateral member 2212 is partitioned to confront the partitioned ends to each other with the C shaped portion of the vertical member 2211 in between. The partitioned ends of the lateral member 2212 are mutually coupled by a joint member 2213 thrust in the vertical member 2211.

The joint member 2213 has a crossed shape. After the vertical member 2211 and the lateral member 2212 are assembled in a cross, the joint member 2213 is forcibly pushed into the intersection from the rear so that a vertical core portion 2214 is engaged in the central C-shaped portion of the vertical member 2211 and a lateral core portion 2215 is engaged in the central C-shaped portion of the lateral member 2212.

The inner frame member 222 is made of aluminum alloy the frame 2 1, and assembled in a quadrilateral frame with the alloy-made extruded 1 elongated-materials. An opening is formed in the inner frame member 222.

The edge of the glass plate 220 is pressured into the opening through a packing member 223, thereby the inner frame member 222 is fitted onto the margin of the glass plate 220. Incidentally, the end of the latticed member 221 is placed to touch the inner frame member 222 or to confront it with a slight space.

The inner frame member 222 is provided with the two-stepped sectional arc-shaped portion at the packing member 223 on the inside and outside of a room. Two cylindrical ornamented surfaces 242 and 243 are fon-ned on the arc-shaped portions. The two arc-shaped portions are arranged with concavity and convexity, in which the inner and outer faces of the arc-shaped portion have a concentric circle shape, so that the thickness is uniform.

In order to fit the inner frame member 222 into the frame 2 1, an abutting member 224 and a connecting member 225 are provided in each of the frame members 211 to 214.

The abutting member 224 is formed continuously from each of the frame members 211 to 214, and extended in the direction along the glass plate 220 at each side of the frame members 211 to 214 which faces the outside of a room.

The connecting member 225 is positioned closer to the inside of a room than the abutting member 224. In addition, the connecting member 225 is made of elastic materials and has a base which is fixed along each of the frame members 211 to 214 with a screw or the like, and a lug portion 226 projecting from the center of the base.

The lug portion 226 is bent from the root, projecting from the base, toward the abutting portion 224, and slopes so that the end of the lug portion 226 is set away from each of the frame members 211 to 214. The end of the lug portion 226 is maintained to confront the middle portion of the abutting member 224 with a specified space.

In the inner frame member 222, a side face 227 confronting the inside 21 of a room (an inside-room side face 227) is formed to touch each of the frame members 211 to 214. A side face 228 confronting the outside of a room (an outside-room side face 228) is formed until a position distant from each of the frame members 211 to 214 with a specified space, which is shorter than the inside-room side face 227. The end of the outside- room side face 228 is formed at a position closer to each of the frame members 211 to 214 than the end of the lug portion 226.

The inner frame member 222 can be inserted from the inside of a room into the inside of the frame members 211 to 214 and pushed toward the outside of a room in a parallel state. Continuing the above insert operation, the outside-room side face 228 touches the lug portion 226, and conquers the lug portion 226 along the slope of the lug portion 226 while elastically deforming the lug portion 226 toward the frame members 211 to 214. In addition, the face of the outside-room side face 228 is abutted to the abutting member 224. The other face opposite the inside of a room is pressed toward the outside of a room by the lug portion 226 to be stably supported by being clamped between the abutting member 224 and the lug portion 226. In this point, the abutting member 224 is a stopper in the present invention, and the connecting member 225 including the lug portion 226 is a one-way hook, in which an elastic concavoconvex engaging means is composed of the abutting member 224, the connecting member 225 and the side face 228.

The fixed-window panel 22 is fitted into the fi-ame 21 with the inner frame member 222 and the peripheral structure as described thus far.

Qpenable window panel As shown in Fig. 4, the openable window panel 23 has a door knob 231 on one vertical side and is connected with the frame 21 through hinges (not shown) on the other vertical side so as to be opened by pivoting on the hinge side as an axis. The openable window panel 23 has a transparent glass plate 230, a latticed member 231 oriented toward the inside and outside of a room which is supported along each of the surfaces of the glass plate 230, and an inner frame member 232 which is fitted onto the margin of the glass 22 plate 230.

The latticed member 231 is the same as the aforementioned latticed member 221 of the fixed-window panel 22, which is adhered to the glass plate 230 with the double-sided adhesive tape, and a cylindrical ornamented surface 244 is formed on the arc-shaped portion of the latticed member 23 1.

The arc-shaped member has an outward convexity, in which the inner and outer faces have a concentric circle shape, so that the thickness is uniform.

The inner frame member 232 is made of aluminum alloy like the frame 21, and assembled in a quadrilateral frame with the alloy-made extruded elongated-materials. An opening is formed in the inner frame member 232. The edge of the glass plate 230 is pressured into the opening through a packing member 233, thereby the inner frame member 232 is fitted onto the margin of the glass plate 230. Incidentally, the end of the latticed member 231 is placed to touch the inner frame member 232 or to confront it with a slight space.

The inner frame member 232 is formed with the two-stepped sectional arc-shaped portion at the packing member 233 on the inside and outside of a room. Two cylindrical ornamented surfaces 245 and 246 are formed on the arc-shaped portions. The two arc-shaped portions are arranged with concavity and convexity, the front and rear faces of the arc shaped portion having a concentric circle shape, so that the thickness is uniform On each inner face of the stile members 211 and 212 and the intermediate rail member 214 which surround the openable window panel 23, an abutting member 235 is formed for abutting an outside-room side face 234 of the inner frame member 232.

The abutting member 235 is formed continuously from each of the frame members 211, 212 and 214. A door stopper member 236, such as rubber having cushioning properties and water-proof, is formed on the end face of the abutting member 235 which is oriented toward the openable window panel 23. The end face of the abutting member 235 is abutted 23 through the door stopper member 236 to the openable window panel 23.

An inside-room side face 237 is forTned to be longer than the outside room side face 234 of the inner frame member 232. A lip member 238, such as rubber having cushioning properties and water-proof, is formed on the end of the side face 237, in which the end of the lip member 238 slidably touches each surface of the frame members 211, 212 and 214. However, when the frame 21 does not have a bottom rail member, the inner fi-ame member 232 corresponding the bottom side of the openable window panel 23 can be omitted to have the lip member 238 slidably touching the frame member.

Each of the frame members 211 to 214 assembling the frame 21 is the same as each of the frame members 111 to 114 on the first embodiment as described above. The intermediate rail member 214 has a rectangularshaped cross-sectional face, and the top rail member 213 and the stile members 211 and 212 have an approximately C-shape in section, each of which have a main face portion 25 1, stand portions 252, a step portion 253 and a penetrating portion 257. Similar to the case of the first embodiment, any method, in which the support base 154 (see Fig. 3) is used or a hole is opened in the penetrating portion 157 for screwing or driving, can be applied for the attachment of the stile members 211 and 212 and the top rail member 213 to the inner peripheral surface of the opening 2.

According to the second embodiment as described thus far, the following effects can be listed.

Cylindrical ornamented surface For each sectional arc-shaped portion of the inner frame members 222 and 232 and the latticed members 221 and 231 of the fixed-window panel 22 and the openable window panel 23, each of the cylindrical omamented surfaces 241, 242, 243, 244, 245 and 246 can be continuously formed on the margin of the fixed-window panel 22 and the openable window panel 23. The latticed members 221 and 231 and the inner frame members 222 and 232, including the sectional arc-shaped portions, are 24 formed by the continuous extrusion molding, thereby achieving the sash for the opening, having the ornamented surface to satisfy demand in Southeast Asia, at low cost and with eases.

In each of the sectional arc-shaped portions for forming the cylindrical ornamented surfaces 241 to 246, the rear face is a concentric arc shape with the front face, so that the thickness is uniform. Thereby the thickness of the extrusion-molded member is uniform at each point and the formability can be improved and the materials can be decreased.

Concerning the inner fi-ame member 222 of the fixed-window panel 22, the cylindrical ornamented surfaces 242 and 243 are consecutively and parallel formed. Concerning the inner frame member 223 of the openable window panel 23, the cylindrical ornamented surfaces 245 and 246 are also consecutively and parallel formed. The adjacent cylindrical ornamented surfaces respectively have the concavity in the opposite direction, so that decoration scrupulous in the ornamented surface required in Southeast Asia is successfully presented, thereby being superior in design.

Attachment of the fixed window bod The fixed-window panel 22 placed in the upper division is defined as a fixed window body, and the fixed-window panel 22 is fitted by the elastic concavoconvex engagement of the side face 228 of the inner fi-ame member 222 with the connecting member 225 as a one-way hook, so that the fixed window panel 22 can be smoothly attached into the frame 21, thereby enhancing the efficiency of manufacturing.

Especially, in this embodiment, the glass plate 220 is fitted into the inner frame member 222 in advance, so that the inner frame member 222 and the glass plate 220 can be unitedly handled, thereby achieving the further efficient workability than the case of the first embodiment in which the glass plate is clamped.

The connecting member 225 as the one-way hook has the lug portion 226 having the sloped end, so that the sloped surface of the lug portion 226 results in the guide face, thereby lubricating the processes in which the connecting member 225 is elastically deformed in the direction intersecting the inserting direction and engaged with the inner frame member 222 when the fixed-window panel 22 is attached into the fl---ame2 1.

Particularly, the abutting member 224 as the stopper is formed closer to the outside of a room than the lug portion 226, and additionally, the fixed window panel 22 which is inserted from the inside of a room causes the side face 228 to be clamped between the lug portion 226 and the abutting member 224, so that the fixed-window panel 22 can be smoothly attached from a direction of the frame 21, and moreover, the fixed-window panel 22 can be stably supported by elastically pressing toward the abutting member 224.

Attachment to the opening Tlie attachment of the frame 21 into the opening 2 can be defined as the same process as that of the aforementioned first embodiment, so that the same effects can be obtained.

Others The extrusion-molded members, which assemble the window-sash 20, such as the frame members 211 to 214, the latticed members 221 and 231 and the inner frame members 222 and 232, are made of aluminum alloy, thereby sufficiently exerting the fundamental performance as the window sash 20.

Similar to the case of the first embodiment, an opening direction of the openable window panel can be switched by reversing the front and the back of the window-sash 20.

Third Embodiment invention.

The aforementioned sashes 10, 20 and 30 are mutually coupled by a ribbon window mullion 41 which is placed between the sashes.

The ribbon window mullion 41 is the cylindrical extrusion-molded members having a rectangular-shaped cross-sectional face and made of aluminum alloy. A wedge-shaped engaging projection 411 is formed along each side on the opposite faces of the ribbon window mullion 41. When the stile members 211 and 212 of the sashes 10, 20 and 30 are pressed to be along the engaging projections 411, the engaging projection 411 is elastically deformed inward by the wedge shape, and additionally, the step portion of the root of the wedge shape is engaged with each step portion 153 or 253 of the stile members 211 and 212. By the engagement, the stile members 211 and 212 of each of the sashes 10, 20 and 30 are mutually coupled, with the result that plural sashes 10, 20 and 30 are seriated and attached into the opening 2.

Incidentally, the attachment of the sashes 10 and 30 into the opening 2which are placed at both ends of the seriated sashes, is carried out similarly to the case of the first embodiment.
