Description

  The present invention relates to a glass detachment stopper applied to a window composed of a window frame and glass mounted in the window frame.

  As is well known, a window made of an appropriate synthetic resin such as vinyl chloride and having an inner peripheral surface that defines a rectangular glass housing space and a rectangular glass mounted in the window frame is practically used. It is served. The outer peripheral surface of the glass is slightly smaller than the inner peripheral surface of the window frame, and the window frame is provided with a plurality of pedestals arranged at intervals in the extending direction on the inner peripheral surface of the window frame. Glass is mounted in the glass housing space. Usually, an inner upright portion rising from the inner circumferential surface is formed on the inner side (the indoor side of the building equipped with the window) or the outer side (the outdoor side of the building equipped with the window) of the window frame A glazing material is loaded on the outer side surface or inner side surface of the inner standing part, and on the other side, a pressing edge rising from the inner peripheral surface is mounted on the outer side or the inner side of the window frame body. It is gripped between the pressing edges. In Patent Documents 1 and 2 below, in order to prevent the glass from being detached from the window frame even when the window frame is partially damaged by a fire or the like, a glass detachment stopper is provided on the window frame. It has been proposed to arrange. In particular, when the side of the window frame on which the ledge is mounted is the outdoor side of the building, the glass detachment stopper is important for crime prevention. The press rim can be easily detached from the window frame by using an appropriate tool. If the glass stopper is not provided, the glass can be removed from the window frame by removing the press lip from the window frame. It can be easily removed.

  On the other hand, it has also been proposed to construct a glass from a plurality of glass plates including heat-resistant glass and to make the window a fireproof window. The glass in the fire prevention window, ie, the fire prevention glass, comprises a heat resistant crystallized glass plate and a pair of non-heat resistant glass plates disposed on both sides of the heat resistant crystallized glass plate as disclosed in Patent Document 3 above. Multi-layered fire protection glass is advantageously used. In the case of such a fireproof window, for example, when the fireproof window is exposed to a flame from the outside of the building and heated to about 700 to 800 ° C., the window frame body has a relatively large coefficient of thermal expansion, so that the window frame body expands relatively large. On the other hand, the glass plate constituting the fireproof glass has a relatively small coefficient of thermal expansion, so that the distance between the inner peripheral surface of the window frame and the outer peripheral surface of the fireproof glass is increased. Between the inner peripheral surface of the window frame and the outer peripheral surface of the fire glass, a heating foaming agent that starts to expand usually at about 250 to 300 ° C. is disposed. A void is generated between the inner peripheral surface of the frame and the outer peripheral surface of the fireproof glass, and the flame enters the building through the void and tends to damage the fireproof property. In order to avoid such a tendency, the interval between the inner peripheral surface of the window frame body and the outer peripheral surface of the fire glass during the initial assembly (therefore, the above-mentioned cradle disposed on the inner peripheral surface of the window frame body). (Thickness) is desired to be made as small as possible, but considering the manufacturing tolerance of the window frame, etc., in order to allow the fireproof glass to be attached to the window frame sufficiently and reliably, It is convenient to set the thickness of the pedestal to about 5.0 mm. And when the thickness of the cradle is set to about 5.0 mm, the main part (that is, on the outer side and / or the inner side of the fireproof glass) composed of the base member and the cover member combined therewith. The thickness of the portion excluding the standing upright part) needs to be smaller by about 0.5 to 1.0 mm than the thickness of the cradle. Therefore, in the glass disengagement stoppers disclosed in Patent Documents 1 and 2 above, the thickness of the main part necessarily is the thickness of the metal plate forming the base member and the cover member due to the form thereof. It was substantially difficult to make the thickness of the base part about 0.5 to 1.0 mm smaller than the thickness of the cradle. If the thickness of the metal plate forming the base member and / or the cover member is excessively reduced to reduce the thickness of the main part of the glass stopper, the strength of the base member and / or the cover member is reduced. And the function of the glass stopper is damaged.

  The present invention has been made in view of the above-mentioned facts, and its main technical problem is that it can be manufactured at a sufficiently low cost, a cover member can be easily combined with a base member, and a function of preventing glass from coming off. It is to provide a new and improved glass stopper that allows the thickness of the main part to be set sufficiently thin in spite of being maintained without damage.

  As a result of intensive studies, the present inventors have found that the main technical problem can be achieved by making the base member and the cover member into a unique form that is completely different from the conventional form.

That is, according to the present invention, as a glass slip-off preventing device that achieves the main technical problem, the inner peripheral surface includes a window frame body that defines a rectangular glass housing space and a rectangular glass mounted in the glass housing space. A glass detachment stopper applied to a window, comprising: a base member fixed to an inner peripheral surface of the window frame and a cover member combined with the base member;
The base member is formed of a single metal plate, and is flat along the inner peripheral surface of the window frame and fixed to the inner peripheral surface of the window frame; Both wings rise from both side edges of the base and then extend outward in the width direction in parallel to the base, and the base has a slant extending in a direction away from the surface of the base toward one edge. Pieces are formed,
The cover member is formed of a single metal plate and has a flat base, an extension located on both sides of the base and extending beyond one edge of the base and the base from the other end of the base An upright portion extending perpendicularly to the base, and an opening is formed in the base,
The free end of the punched piece of the base member is displaced from the upper surface of the base of the base member by a dimension corresponding to the thickness t of the base of the cover member, and the two wings of the base member rise The dimension h is 1.0 to 2.0 times the thickness of the extended piece of the base of the cover member,
The cover member locates the base portion of the cover member on the surface of the base portion of the base member and places the extension portion below the wings of the base member relative to the base member Combined with the base member by moving in a direction towards the one end edge of the base member and positioning the punched piece of the base member in the opening of the cover member;
The raised portion of the cover member is positioned proximate to the outer or inner surface of the glass;
There is provided a glass stopper characterized in that.

  Preferably, the two wing portions of the base member rise from the one end edge side portion of the both side edges of the base portion. In particular, the two wings of the base member rise from the one side edge side of the both side edges of the base, and then extend outward in the width direction and in the direction toward the other edge of the base, and then downward Hang down. Conveniently, the stamped piece is rectangular and the opening is also rectangular. Two punched pieces are formed in the base portion of the base member at intervals in the width direction, and two openings are formed in the base portion of the cover member at intervals in the width direction. Is preferred. Preferably, the base member has an upstanding portion extending perpendicularly to the base from the inner edge. The thickness T1 of the main portion excluding the rising portion is smaller by 0.5 to 1.0 mm than the thickness T2 of the pedestal interposed between the inner peripheral surface of the window frame and the outer peripheral surface of the glass. Is desirable.

  According to the glass slip stopper of the present invention, it can be manufactured at a sufficiently low cost, the cover member can be easily combined with the base member, and the glass slip stopper function can be maintained without being damaged. Nevertheless, the thickness of the main part can be reduced to a sufficiently small value which is three times or slightly larger than the thickness of the metal plate forming the base member and / or the cover member.

Sectional drawing which shows a part of window shown in FIG. FIG. 2 is a partial perspective view showing a cradle and a glass detachment stopper used in the window shown in FIG. FIG. 2 is an exploded perspective view showing a glass slip-off stopper used in the window shown in FIG.

  Hereinafter, with reference to an accompanying drawing, the typical example of a window and the suitable embodiment of the glass stop stopper comprised according to this invention used for this are further explained in full detail.

  Referring to FIG. 1 and FIG. 2, the window denoted as a whole by the number 2 is composed of a window frame body 4 and a glass 6 attached to the window frame body 4. The window frame body 4 that is conveniently formed from a suitable synthetic resin such as vinyl chloride has an upper frame member 8, a lower frame member 10, a one-side frame member 12, and an other-side frame member 14, and includes an upper frame. Both side ends of the member 8 are joined to the upper end of the one side frame member 12 and the upper end of the other side frame member 14, respectively, and both side ends of the lower frame member 8 are joined to the lower end of the one side frame member 12 and the lower end of the other side frame member 14, respectively. It is done. Flat inner peripheral surfaces 16 of the upper frame member 8, the lower frame member 10, the one-side frame member 12, and the other-side frame member 14 constituting the window frame body 4 define a glass housing space that is rectangular as a whole. The glass 6 mounted in the glass housing space of the window frame 4 is rectangular as a whole, and its outer peripheral surface is somewhat smaller than the inner peripheral surface of the glass housing space (the mounting manner of the glass 6 will be described later).

  Continuing with reference to FIG. 2, in the illustrated embodiment, the upper frame member 8, the lower frame member 10, the one-side frame member 12 and the other-side frame member 14 constituting the window frame 4 are the same. An inner protrusion 18 having a cross-sectional shape and extending perpendicularly to the inner circumferential surface 16 on the inner side of the inner circumferential surface 16 (the indoor side of a not-shown building equipped with the window 2) Is formed. A glazing material 20 that is conveniently formed of a flexible synthetic resin such as foamed vinyl chloride is mounted on the outer surface of the protruding end of the inner protruding portion 18. On the other hand, on the outer side of the inner peripheral surface 16 (the outside of the building (not shown) equipped with the window 2) is attached a rim 22 which is advantageously made of synthetic rubber or soft synthetic resin There is. The outer peripheral edge of the glass 6 is held between the glazing material 20 and the pressing edge 22. The upper frame member 8, the lower frame member 10, the one-side frame member 12, the other-side frame member 14, and the glazing material 20 and the pressing edge 22 that are mounted on these may be in a known form, Therefore, the detailed description about these is omitted in the present specification.

  As clearly understood by referring to FIG. 2, the glass 6 in the illustrated embodiment is a fireproof glass, the heat-resistant glass 24 located in the center, and one side of the heat-resistant glass plate 24 (on the left side in FIG. 2, One-sided non-heat-resistant glass plate 26 arranged at an appropriate distance on the outside of the building and parallel to the heat-resistant glass plate 24 and the other side of the heat-resistant glass plate 24 (right side in FIG. And the other non-heat resistant glass plate 28 arranged in parallel with the heat resistant glass 24 at an appropriate interval. The heat-resistant glass plate 24 is advantageously a heat-resistant crystallized glass plate having a remarkably small coefficient of thermal expansion or substantially zero. As a suitable heat-resistant crystallized glass plate, a heat-resistant crystallized glass sold by Nippon Electric Glass Co., Ltd. under the trade name “Firelight” can be exemplified. The heat-resistant crystallized glass constituting the heat-resistant glass plate 24 is preferably about 3 to 6 mm thick. The one-side non-heat-resistant glass plate 26 and the other-side non-heat-resistant glass plate 28 can be composed of ordinary float glass plates. The thickness of the one-side non-heat-resistant glass plate 26 and the other-side non-heat-resistant glass plate 28 may be about 3 to 5 mm.

  If desired, a composite crime prevention non-corrugated non-heat resistant glass plate 26 and / or other non-heat resistant glass plate 28 formed by joining two non-heat resistant glasses with a crime prevention layer interposed. It can also be composed of a heat resistant glass plate (not shown). The security layer can be formed from a polyvinyl butyral film or a polycarbonate plate. When such a composite crime prevention non-heat resistant glass plate is used, the glass has a fire prevention property as well as a crime prevention property (high resistance to breakage using a driver or a bar).

  Between the outer peripheral edge of one side surface (left side surface in FIG. 2) of the heat resistant glass plate 24 and the outer peripheral edge portion of the inner surface (right side surface in FIG. 2 facing the heat resistant glass plate 24) of the non-heat resistant glass plate 26. The spacer member 30 is disposed, and the sealing materials 32 and 34 are disposed. More specifically, the spacer member 30 is advantageously formed in a hollow shape from an appropriate metal such as aluminum, stainless steel or iron, or a composite material of these metals and a hard synthetic resin such as polyamide resin. A primary sealing material 32 which may be butyl or polyisobutylene is applied to both side surfaces of the spacer member 30, and the outer peripheral edge of one side surface of the heat resistant glass plate 24 and the outer peripheral edge of the inner surface of one side non heat resistant glass plate 26. The portion is in close contact with the primary sealing material 32 and joined to the spacer member 30. Thereafter, the outer peripheral surfaces of the spacer member 30 and the primary sealing material 32 are filled with a secondary sealing material 34 which may be silicone or polysulfide, and the space 36 between the heat resistant glass plate 24 and the one-side non-heat resistant glass 26 is sealed. Be done. Also between the outer peripheral edge of the other side of the heat resistant glass plate 24 (right side in FIG. 2) and the outer peripheral edge of the inner surface of the non-heat resistant glass plate 28 (the left side facing in FIG. 2 facing the heat resistant glass plate 24). Similarly, the spacer member 30 is disposed, and the sealing materials 32 and 34 are disposed. That is, the primary sealing material 32 which may be butyl or polyisobutylene is applied on both side surfaces of the spacer member 30, and the outer peripheral edge of the other side surface of the heat resistant glass plate 24 and the inner surface of the other non-heat resistant glass plate 28. The outer peripheral edge portion is in close contact with the primary sealing material 32 and joined to the spacer member 30. After that, the outer peripheral surfaces of the spacer member 30 and the primary sealing material 32 are filled with a secondary sealing material 34 which may be a silicone type or a polysulfide type, so that a space 38 between the heat resistant glass plate 24 and the other non-heat resistant glass 28 is formed. Be sealed.

The inner surface of the one-side non-heat-resistant glass plate 26 facing the heat-resistant glass plate 24 (right side surface in FIG. 2) and the inner surface of the other-side non-heat-resistant glass plate 28 facing the heat-resistant glass plate 24 (left side surface in FIG. 2). Advantageously, a silver-based low emission film 40 is coated. In the embodiment illustrated in FIG. 2, the spacer member 30, the primary seal material 32 and the secondary seal material 32 are disposed on the inner surface of the one side non-heat resistant glass plate 24 and the inner surface of the other side non heat resistant glass plate 26. The outer peripheral portion is not coated with the silver-based low emission film, but the silver-based low emission film 40 is coated over the entire area other than the outer peripheral portion. It may also be contemplated to coat non-silver based low emission films, such as tin oxide (SnO ₂ ) films, but non-silver based low emission films are effective because they have higher emissivity compared to silver based emission films 40. For fire protection, it is desirable to coat a silver-based radiation film 40 with a sufficiently low emissivity. On the other hand, the silver-based low radiation film 40 is inferior in physical characteristics and easily damaged compared with the non-silver-based low radiation film, but is coated on the inner surface, not the outer surface of the one-side non-heat-resistant glass plate 26 and the other-side non-heat-resistant glass plate 28. Therefore, problems are not caused by inferior physical properties.

  In the glass 6 as described above, for the flame from the outside of the building, the one-side non-heat-resistant glass plate 26 on which the flame acts directly is damaged (according to the experience of the present inventors, etc. Even if the outer surface of the one-side non-heat-resistant glass plate 26 is covered with a low radiation film as disclosed in the above-mentioned Patent Document 3, the one-side non-heat-resistant glass plate 26 is damaged by the flame that acts directly). The heat resistant glass plate 24 is maintained without being damaged. Then, the high temperature caused by the flame, together with the heat insulating function by the sealed space 38, is a silver-based low-emission film 40 coated on the inner surface of the other non-heat resistant glass plate 28 protected by the heat resistant glass plate 24. The reflection action effectively blocks conduction into the structure. Similarly, for the flame from the inside of the building, the other non-heat resistant glass plate 28 on which the flame directly acts is damaged, but the heat resistant glass plate 24 is maintained without being damaged. And, the high temperature due to the flame is caused by the reflection of the silver-based low-emission film 40 coated on the inner surface of the one-side glass plate 26 protected by the heat resistant glass plate 24 together with the heat insulation of the sealed space 36. And conduction outside the building is effectively blocked.

  Referring to FIG. 1, in the illustrated embodiment, the flat inner periphery of each of the upper frame member 8, the lower frame member 10, the one-side frame member 12, and the other-side frame member 14 constituting the window frame body 4. Two cradles 42 are disposed on the surface 16 (see FIG. 2) at intervals in the extending direction. Further, the central portion of the flat inner peripheral surface 16 (see FIG. 2) of each of the upper frame member 8, the lower frame member 10, the one-side frame member 12 and the other-side frame member 14 constituting the window frame body 4. Is provided with a glass detachment stop 44 constructed in accordance with the present invention. The glass stopper 44 can be disposed only on the upper frame member 8 and the lower frame member 10 or only on the one-side frame member 12 and the other-side frame member 14, or the upper frame member 8 constituting the window frame body 4. Alternatively, two or more glass stoppers 44 may be disposed at intervals in the extending direction on each of the lower frame member 10, the one-side frame member 12 and the other-side frame member 14. Further, although not shown, the receiving frame 42 and the glass on the flat inner peripheral surface 16 of each of the upper frame member 8, the lower frame member 10, the one-side frame member 12, and the other-side frame member 14 constituting the window frame body 4. An appropriate heating foaming agent such as a foaming agent containing expansive graphite that begins to foam at about 250 to 300 ° C. is also disposed in a portion where the stopper 44 is not disposed.

  The description will be continued with reference to FIG. 3 together with FIG. 1. Each of the receiving bases 42, which can be formed from an appropriate synthetic resin such as vinyl chloride, has a rectangular parallelepiped block shape and constitutes the window frame 4. The flat inner peripheral surface 16 of each of the frame member 8, the lower frame member 10, the one-side frame member 12 and the other-side frame member 14 is fixed by an appropriate bonding means such as an adhesive. When the glass 6 is fireproof glass, the cradle 42 is desirably relatively thin, and its thickness T2 is desirably about 5.0 mm. Further, as clearly shown in FIG. 3, the upper surface of the outer edge of the pedestal 42 is inclined downward toward the outer side, and the glass 6 is carried in when the glass 6 on the pedestal 42 is carried in as described later. Is preferably guided smoothly.

  Referring to FIG. 4 together with FIG. 3, the glass stopper 44 configured according to the present invention includes a base member 46 and a cover member 48. Both the base member 46 and the cover member 48 are formed by applying required processing to a single metal plate. The metal plate for forming the base member 46 and the cover member 48 is preferably a relatively high strength metal plate such as stainless steel having a thickness t of about 1.0 mm.

  The base member 46 in the illustrated embodiment includes a base portion 50, both wing portions 52, and an upright portion 54. The base 50 is flat, and as clearly understood from FIG. 3, the flat inner portions of the upper frame member 8, the lower frame member 10, the one-side frame member 12, and the other-side frame member 14 constituting the window frame body 4. It is extended along the circumferential surface 16. A circular hole 56 is formed at the center in the width direction of one end of the base 50 (the upper left side in FIG. 4 and the portion located on the indoor side of the structure equipped with the window 2) The screw 58 (FIG. 3) is fixed to the inner peripheral surface 16 by being screwed onto the inner peripheral surface. At the other end of the base 50 (the lower right side in FIG. 4 and located outside the building on which the window 2 is installed), two punched pieces 60 are spaced apart in the width direction. Is formed. Each of the punched pieces 60 is inclined and extended in a direction away from the surface of the base 50 (upper left direction in FIG. 4) toward the one end edge. Each of the punched pieces 60 is preferably rectangular, and cuts three sides, leaving one side of the rectangular part (side extending near and parallel to the other end edge of the base 50), It is formed by displacing the free end in a direction away from the surface of the base 40. The free end of the punched piece 60 is displaced upward from the surface of the base 50 by a dimension corresponding to the thickness of the metal plate forming the cover member 48 (and hence the thickness of the base 56 described later of the cover member 48). Is preferred. If desired, instead of the two punched pieces 60, a single punched piece 60 or three or more punched pieces 60 may be formed at appropriate intervals in the width direction or inward and outward directions. . It is important that each of the wing portions 52 of the base member 46 rises from both side edges of the base portion 50 and then extends in parallel with the base portion 50 outward in the width direction. In the illustrated embodiment, each of the wing portions 52 rises from one end side portion of both side edges of the base portion 50, extends to the outside in the width direction in parallel with the base portion 50 following the rising portion 52 a, and others. It is comprised from the parallel extension part 52b extended to an end side, and the drooping part 52c hanging from the other end side part of the parallel extension part 52b. The rising dimension h of the rising portion 52 is advantageously 1.0 to 2.0 times, in particular 1.2 to 1.5 times the thickness t of the metal plate forming the cover member 46. . If desired, the drooping portion 52c can also be suspended from the other half of the parallel extension 52b instead of from the other half or from the entire parallel extension 52b. The standing portion 54 extends perpendicularly to the base portion 50 from one end edge of the base portion 50.

  The cover member 48 includes a base portion 62, an extension portion 64, and an upright portion 66. The base 62 is flat, and two openings 68 are formed at intervals in the width direction. Each of the openings 68 has a rectangular shape corresponding to the shape of the punched piece 60, and each dimension of the opening 68 is somewhat larger than the dimension of the punched piece 60. If desired, the openings 68 corresponding to the punched pieces 60 may be replaced by a single opening 68 instead of the two openings 68 or three or more openings 68 with appropriate spacing in the width direction or in and out directions. Can also be formed. The extensions 64 are located on both sides of the base 62 and extend beyond one end of the base 62 (upper left end in FIG. 4) away from the upright 66. Each of the extending portions 64 and the base portion 62 are continuous at the other end portion (the lower right end portion in FIG. 4), but each of the extending portions 64 is provided at one end side portion of the continuous other end portion. A groove 70 is formed between the base and the base 62. The front surface and the back surface of the main portion (a portion excluding the extended end portion) of the extending portion 64 are flush with the front surface and the back surface of the base portion 62 except for the extended end portion. The extending end portion of the extending portion 64 is somewhat inclined toward the extending end in a direction away from the back surface (downward in FIG. 4). The upright portion 66 extends perpendicularly to the base portion 62 from the other end edge of the base portion 62 (the right lower end edge in FIG. 4 and the outdoor side edge of the building).

  The base member 46 and the cover member 48 are combined in the form shown in FIG. 3 (the combination mode will be described later). As clearly understood by referring to FIG. 3, in the glass stopper 44 constructed according to the present invention, the upright portion 54 of the base member 46 in a state where the base member 46 and the cover member 48 are combined. The thickness T1 of the main portion excluding the standing portion 66 of the cover member 48 is the thickness of the metal plate forming the base member 46 and the cover member 47 due to the unique form of the base member 46 and the cover member 48. It can be set to a sufficiently small value that is three times the length t or slightly larger than this. The thickness T1 of the main part of the glass stopper 43 is preferably about 0.5 to 1.0 mm smaller than the thickness T2 of the cradle 42 described above.

  Next, the assembly mode of the window 2 will be described with reference to FIGS. The base member 46 of the glass stopper 44 is fixed to a required portion of the window frame body 4 while the pressing edge 22 is detached, but the cover member 48 of the glass stopper 44 is still combined with the base member 46. In a state where it is not, the glass 6 is moved and attached to the glass housing space of the window frame 4 from the outside to the inside (from left to right in FIG. 2). The outer peripheral edge of the glass 6 mounted in the glass housing space is disposed on the inner peripheral surface 16 of the upper frame member 8, the lower frame member 10, the one-side frame member 12, and the other-side frame member 14 that constitute the window frame body 4. The outer peripheral edge of the inner surface of the glass 6 is in close contact with the glazing material 20 of the window frame 4. Next, the cover member 48 of the glass stopper 44 is combined with the base member 46. At this time, the base portion 62 of the cover member 48 is positioned on the upper surface of the base portion 50 of the base member 46, and the extended portion 64 of the cover member 48 is positioned on the lower surface of the parallel extending portions 52 b of both wing portions 52 of the base member 46. With the lower position, the cover member 48 is forcibly moved to one end of the base member 46 (i.e., the indoor side of the building and the right side in FIG. 2). Accordingly, the base 62 of the cover member 48 moves over the punched piece 60 of the base member 46 due to elastic deformation of the punched piece 60 of the base member 46 and the base 62 of the cover member 48, and the punched piece of the base member 46 is moved. 60 are received within the opening 68 of the cover member 48. As described above, in the state where the cover member 48 is combined with the base member 46 as required, the thickness of the main part excluding the rising parts 54 and 66 in the glass disengagement stopper 44 is smaller than the thickness of the pedestal 42 In the state where the glass 6 is accommodated in the glass accommodating space of the body 4, the cover member 48 can be combined with the base member 46 as described above without any problem. When the cover member 48 of the base member 46 is combined as required, the relative movement of the cover member 48 relative to the base member 46 in the direction parallel to the base 50 is within a predetermined range by the cooperation of the punched piece 60 and the opening 68. And also by the cooperation of the base 46 and the base 50 and the parallel extension 52b and the extension 64 of both wings 52, the cover member perpendicular to the base 50 with respect to the base member 46. Therefore, the relative movement in a certain direction is limited to a predetermined range, and thus the cover member 48 can be sufficiently prevented from being detached from the base member 46. After combining the cover member 48 with the base member 46 of the glass stopper 44 as described above, the upper frame member 8, the lower frame member 10, the one-side frame member 12, and the other-side frame constituting the window frame body 4. A pressing edge 22 is attached to the outside of the member 14, and the outer peripheral edge of the glass 6 is gripped by the grading material 20 and the pressing edge 22 of the window frame body 4. As clearly understood by referring to FIG. 2, the upright portion 54 of the base member 46 in the glass stopper 44 is positioned so as to face the outer peripheral edge of the inner surface of the glass 6 with a slight gap. The upright portion 66 of the cover member 48 of the glass stopper 44 is positioned opposite to the outer peripheral edge of the outer surface of the glass 6 with a slight gap.
