Description

  The present invention relates to a louver glass (also referred to as a blade glass or jalousie glass) used for a louver window installed in an opening or the like of a building such as a house, and relates to a crime prevention measure. It is effective in preventing damages such as cracks carved by a kind from the starting point, and other breaching damages, and damage to the louver glass being removed from the support bracket.

Conventional types of louver windows include louver windows with end caps that can be mounted and locked at the same time by one-touch operation by placing end caps on both ends of the louver glass and inserting them into the support bracket. There is a clip-mounted louver window equipped with a clip-type support bracket without a gap.

  FIG. 11 is a cross-sectional view schematically showing a general configuration of a louver window. Conventionally, a louver glass G is generally made of a plate glass having a thickness of 6.0 to 6.8 mm, such as an end cap type or a clip type. The support fitting K is attached to the main body H of the louver window, and is connected to the operator P via the interlocking frame F. The louver glass G is configured to open and close by rotating around the long side of the louver glass G in an armor shape.

  As a security problem in the louver window, when using a louver glass with a cap attached to an end cap or a louver window with a clip attached, bare louver glass (with a glass plate cut into a predetermined size and chamfered) is used. There has been a problem that glass is cracked and pulled out starting from scratches carved by glass cutting or nippers, or rarely forcibly cracked by bar or the like. In the following, this problem is referred to as “discount” damage. Another problem is that the louver glass is removed from the support fitting in a clip-mounted louver window that does not have a function of locking the louver glass. Hereinafter, this problem will be referred to as “unplugging” damage.

  In recent years, louver windows with end caps occupy the majority, and louver windows with clip mechanisms without a locking mechanism have been installed less frequently. In the direction of termination. However, the breakage damage is a damage that occurs when a bare louver glass is used, and also occurs in a louver window fitted with a clip, and the problem of crime prevention has been focused on preventing the breakage damage.

  The known laminated glass using the interlayer film is easily bent and deformed when the glass layer is cracked, and can be removed from the support fitting. Therefore, any louver window has a bare thickness of 6.0 to 6.8 mm. Louver glass is exclusively used. The cut damage caused by louver glass being cracked and extracted from scratches carved by glass cutting, etc., is damage that occurs when template glass or netted glass is used in a bare state. Bare louver glass Currently, there is a risk that damage will occur in all louver windows. Even if it is a louver window with an end cap that has an excellent function that can be attached and locked with one touch operation, as long as bare louver glass is used, it can be broken or bent using glass cutting etc. It was completely defenseless against the unforeseen damage caused by sampling, and needed countermeasures. In addition, the naked louver glass has a problem that it is inferior in design.

  As an example of cutout damage, a linear flaw is made in the short side direction when glass is cut, a bite is put on the side when nippers are used, and an adhesive tape for silencing is used if necessary. When the louvered glass is closed, the tip of the bag, bar, or nail clipper is inserted into the gap between the louvered glass that overlaps the armor. In some cases, the louver glass can be easily divided by being cracked from the scratch if it is sandwiched with pliers or a yatco to apply a force in the direction of bending to the point of the scratch. . Since the louver glass is only fitted to the support fitting, the louver glass in a state of being divided or bent can be easily pulled out by pulling in the direction of the cut end. The time required for these does not take several seconds per louver glass.

Incidentally, the louver glass in which a plate glass is fitted to a sash having a groove shape in cross section through a grechan is the same as a conventional glass window and has no adhesive force, so if the glass is cracked, it is broken. The glass piece is not glued to the sash, it just fits in, so it is easily removed and the hand is inserted through the opening where the glass piece is removed, and the lock is released. There was a problem that it could not prevent the damage.
Further, in order to improve the airtightness of the louver window, a louver glass in which an airtight material made of an elastic material is attached in the vicinity of the long side of the louver glass is disclosed in, for example, JP-A-11-62420, JP-A-10-122210, Although proposed in No. 9-133384 and the like, the hermetic material made of an elastic material is bent together when the louver glass is cracked, and therefore, there is a problem that it cannot prevent the breakage damage.

  The technique of cutout damage is a work that can be done quickly without failure by using glass cutting etc. as a tool without making any noise, and if the technique is known to thief friends, it is not the ratio of conventional removal damage There is a possibility that it will spread to extremely large damage, and it is feared that it will be related to the survival of the louver window. The present invention has been made in view of the above-mentioned concerns, and a first object of the present invention is to provide a louver glass having a new configuration that can easily prevent the above-mentioned damage caused by cutting. Furthermore, in view of the fact that the louver glass with the new configuration requires acceptance of the aesthetics as a window in order to be accepted by the world, it is essential that the louver glass has an attractive configuration with excellent design. The improvement of the design is also an issue.

  The second problem of the present invention is directed to a clip-mounted louver window and is intended to prevent unplugging damage that occurs because the lock mechanism is not provided at the same time as preventing the above-mentioned cutting damage. . Although the problem of unplugging damage is in the direction of termination as described above, it was made in view of the fact that there are many clip-attached louver windows in the existing louver windows. The present invention has an object to prevent damage from being removed and cut off at the same time by replacing bare louver glass with the louver glass of the present invention without modification.

In the case of using, it is characterized in that the thickness of the peripheral portion is increased by forming it on the laminated glass so that a shape suitable for the support bracket for 6 mm can be obtained. It should be noted that even if the adhesive layer interposed between the impact-resistant material layer and the glass layer on the anti-contact side and the side surface is omitted, there is no problem in the crime prevention function, but if omitted, the appearance may be a triple structure. The function falls into the category of single structure.

  According to a sixth aspect of the present invention for solving the first problem, in the louver glass according to any one of the first to fifth aspects, the laminated glass portion constituting the laminated glass includes the louver glass. Is a portion excluding the support bracket mounting portion that is covered by the support bracket when mounted on the support bracket, and is formed on an exposed portion exposed between the support brackets. To provide louvered glass.

  In the louver glass according to claim 6, the laminated glass portion is limited to the exposed portion, and the support fitting mounting portion is left in a bare glass state, thereby increasing the thickness. It is characterized in that it is configured such that a portion that does not increase functions according to the purpose. In other words, the exposed part that is subject to attack from a third party is strongly prevented from being damaged by providing a laminated glass part as a thickness-increasing part, and the supporting bracket mounting part that fits into the supporting bracket is an exposed part. Even if a laminated glass part is provided, even if a plate glass having a sufficient thickness of 6.0 to 6.8 mm is used so that the thickness does not increase, a shape suitable for a 6 mm support bracket can be obtained. It is characterized by the configuration.

  In invention of Claim 7 which solves the said 2nd subject, in the louver glass in any one of Claim 1 thru | or 6, the impact-resistant material layer which comprises the said laminated glass part consists of a metal layer, A louver glass characterized in that the metal layer is provided with a tongue piece that appears on a track when the clip portion of the support metal member opens and closes and seals the movement of the clip portion so as to be retractable. Is provided.

  The louver glass according to claim 7 is intended for a clip-mounted louver window that does not have a lock mechanism, and does not require any modification of the louver window main body, and only replaces the conventional louver glass with the louver glass of the present invention. It is characterized in that the removal damage and the breakage damage are prevented at the same time by the means.

  The louver glass according to claim 1 has a laminated glass structure in which a part of the louver glass is composed of a glass layer, an adhesive material layer, and an impact-resistant material layer. Even if it is made, the impact-resistant material layer of the other party is strong and does not break, and the bonded glass layer is not peeled off from the impact-resistant material layer and maintains its original shape and bends ( It wo n’t be bent. That is, the louver glass of the present invention does not bend like a conventional laminated glass using an intermediate film, and is not pulled out from the support metal fitting, so that it is prevented from being cut off. The impact-resistant material layer and the glass layer are drastically strengthened by bonding, and the relationship between the two is similar to the relationship between steel and concrete in steel-framed concrete of building construction. The impact material layer and the glass layer corresponding to the concrete aggregate are integrated by the adhesive layer corresponding to the cement to create a strong structure. The louver glass having such a strong structure does not need to have a laminated glass structure in the entire region, and has a sufficient crime prevention function even if it is formed only in a part of the glass. In addition, in a configuration in which some parts are made of laminated glass, even if the impact-resistant material layer is made of an opaque material, the window from the non-laminated glass (single glass) region that occupies most of the area. The daylighting necessary for this is sufficiently obtained. Moreover, the location of the laminated glass further enhances the design of the horizontal stripe pattern unique to the louver window, and the appearance is improved by forming the laminated glass.

In the louvered glass according to claim 2, the laminated glass portion is made of a so-called single-structured laminated glass in which the contact side is made of a glass layer and the anti-contact side is made of an impact-resistant material layer. However, it has excellent functionality for a low price. That is, in the event of an attack of cutout damage, the impact-resistant material layer protects the louver glass from the peripheral portion and functions as a surface lattice, and first, the first-stage defense is achieved. Even if the glass layer is broken by losing this first-stage defense, the broken glass piece adheres to the impact-resistant material layer and does not bend (bend) and is not pulled out of the support bracket. Therefore, the breakage damage is strongly prevented by the two-stage function of the surface lattice function fulfilled by the impact-resistant material layer and the original function fulfilled by the laminated glass portion. In addition, even when a thin plate glass with a thickness of 3 to 5 mm is used, the thickness can be increased to 6.0 to 6.8 mm, which is the same as that of a conventional louver glass, by using a laminated glass at the periphery. Thus, a thickness suitable for the support bracket for 6 mm is obtained, and it can be used for 100% compatibility in the conventional louver window. Further, the non-laminated glass portion (single plate glass portion) occupying most of the area is a thin plate glass having a thickness of 3 to 5 mm, and can be reduced in weight compared to the conventional case.

  In the louver glass according to claim 3, the laminated glass portion is composed of an impact-resistant material layer on both the contact side and the anti-contact side, and between the impact-resistant material layer on the contact side and the anti-impact material layer on the anti-contact side. The sandwiched portion is made of a so-called double-structured laminated glass made of a glass layer, and the function is reinforced by a simple calculation approximately twice as much as that of the single-structured glass according to claim 2. In other words, the glass layer is protected in a sandwich form from both sides by the impact-resistant material layer, and functions as a surface lattice fulfilled by the impact-resistant material layer as one member, and the laminated glass originally fulfilled by the laminated glass portion as the main body portion. Both of these functions are strengthened compared to the single structure of claim 1 and have a large resistance to bending and are not pulled out from the support bracket, so that the damage to the cut is strongly prevented. In addition, even when a thin plate glass with a thickness of 3 to 5 mm is used, the thickness can be increased to 6.0 to 6.8 mm, which is the same as that of a conventional louver glass, by using a laminated glass at the periphery. Thus, a thickness suitable for the support bracket for 6 mm is obtained, and it can be used for 100% compatibility in the conventional louver window. Further, the non-laminated glass portion (single plate glass portion) occupying most of the area is a thin plate glass having a thickness of 3 to 5 mm, and can be reduced in weight compared to the conventional case.

In the louver glass according to claim 4, the laminated glass portion is made of a so-called double-structured laminated glass in which the contact side is made of a glass layer, and the anti-contact side and the side face are both made of an impact-resistant material layer. Compared with the single structure according to the second aspect, the calculation is reinforced approximately twice as much by simple calculation. That is, the glass layer is protected by a two-dimensional wall surface composed of the impact-resistant material layer on the anti-contact side and the impact-resistant material layer on the side surface, and as a double structure according to claim 3, Both the function as the surface lattice fulfilled by the impact-resistant material layer and the original function of the laminated glass fulfilled by the laminated glass portion as the main body are strengthened compared with the single structure of claim 1 and the resistance to bending is large. Therefore, it is not pulled out from the support bracket, and the damage caused by cutting is strongly prevented. In addition, even when a thin plate glass with a thickness of 3 to 5 mm is used, the thickness can be increased to 6.0 to 6.8 mm, which is the same as that of a conventional louver glass, by using a laminated glass at the periphery. Thus, a thickness suitable for the support bracket for 6 mm is obtained, and it can be used for 100% compatibility in the conventional louver window. Further, the non-laminated glass portion (single plate glass portion) occupying most of the area is a thin plate glass having a thickness of 3 to 5 mm, and can be reduced in weight as compared with the conventional case.

In the louver glass according to claim 5, the laminated glass portion is composed of an impact resistant material layer on the contact side, the anti-contact side, and the side surface, and the impact-resistant material layer on the contact side and the anti-impact material layer on the anti-contact side. And the impact-resistant material layer on the side surface is made of a so-called triple-structured laminated glass composed of a glass layer, and the function is simpler than that of the single-structured structure of claim 2 It is strengthened by about 3 times. That is, the glass layer is protected by a three-dimensional wall surface composed of the impact-resistant material layer on the contact side, the impact-resistant material layer on the side surface, and the impact-resistant material layer on the non-contact side, and the impact-resistant material layer as one member fulfills it. Both the function as a surface lattice and the original function of the laminated glass fulfilled by the laminated glass portion as the main body are strengthened compared to the double structure according to claims 3 and 4, and the resistance to bending is further increased and the support metal fittings. It will not be extracted from it, and the damage caused by cutting will be prevented more powerfully. In addition, even when a thin plate glass with a thickness of 3 to 5 mm is used, the thickness can be increased to 6.0 to 6.8 mm, which is the same as that of a conventional louver glass, by using a laminated glass at the periphery. Thus, a thickness suitable for the support bracket for 6 mm is obtained, and it can be used for 100% compatibility in the conventional louver window. Further, the non-laminated glass portion (single plate glass portion) occupying most of the area is a thin plate glass having a thickness of 3 to 5 mm, and can be reduced in weight compared to the conventional case.

In the louver glass according to claim 6, since the laminated glass portion is a portion excluding the support fitting mounting portion and is limited to the exposed portion, the periphery of the plate glass having a thickness of 6.0 to 6.8 mm Even if a laminated glass part is formed on the part, the thickness of the support fitting mounting part does not increase, and the shape remains compatible with the support fitting for 6 mm, and is used for 100% compatibility in the conventional louver window. be able to. In other words, when a plate glass with a maximum thickness of 6.0 to 6.8 mm is used as the louver glass suitable for the support bracket for 6 mm, the exposed portion that does not affect the mounting even if the thickness is further increased. The laminated glass portion is formed to prevent the damage caused by cutting, and the laminated glass portion is not provided in the support fitting mounting portion which causes trouble in mounting when the thickness is further increased. Thus, the louver glass of the present invention using the plate glass of 6.0 to 6.8 mm has the highest glass strength at the same time, and at the same time, when exposed to attack from a third party such as a thief, It has a laminated glass structure that protects it by the face lattice function and the laminated glass function. In addition to the crime prevention effect by the face lattice function and the laminated glass function, the crime prevention effect by the maximum glass strength is further added. Therefore, the effect of preventing breakage damage is also strengthened in terms of glass strength. In summary, according to the present invention, a louver glass having a sufficient crime prevention effect in which a laminated glass portion is provided on a plate glass of 6.0 to 6.8 mm can be provided as a louver glass suitable for a support fitting for 6 mm.

In the louver glass according to the seventh aspect, since the lock mechanism is provided independently on the louver glass side, the lock function is provided by simple means of using instead of the conventional louver glass. Even in a louver window that does not have a locking function, such as a clip-mounted louver window, it is not necessary to modify the main body of the louver window. Can be prevented at the same time, and it is simple and inexpensive.

  The best mode for carrying out the present invention will be described below by way of example with reference to the drawings. In the following examples, all the examples are shown as examples in which the impact-resistant material layer is formed of a metal layer.

Reference) is composed of a glass layer 12, and the non-contact side Y is composed of a metal layer 13. The glass layer 12 and the metal layer 13 are arranged to face each other with the adhesive layer 14 interposed therebetween. The layers are in a one-to-one combination and are made of a so-called single structure laminated glass, and the cost is low for the effect. Since the louver glass 11 is a glass layer on the contact side, the glass layers are in contact with each other (see FIG. 2) when contacting in an armor shape. In addition, the laminated glass portion can be provided partially extending on the short side, and in that case, it may be substituted by attaching a spacer made of a plate-like metal or rubber. .

Since the direction of the louvered glass is reversed in the upper and lower directions, the metal layer 33x that is the contact side X in the upper portion and the metal layer 33y that is the anticontact side Y in the lower portion are continuous in the vertical direction. It is one piece. In other words, the louver glass 31 has a single metal layer provided on both the front and back surfaces of the glass layer 32, and is a combination of one glass layer and two metal layers. It consists of laminated glass with a structure. The contact sides are both metal layers, and the metal layers are in contact with each other when contacting in an armor shape.

The metal layers 33x and 33y are two frame-shaped frames, and are formed of a molded product such as an aluminum plate, a stainless steel plate, or a brass plate. The metal layer (frame body) preferably has an edge width 33c (see FIG. 4) of about 5 to 30 mm, an opening at the center, and a thickness of about 0.5 to 2 mm. As the glass layer 32, colorless or colored template glass or float glass having a thickness of 3 to 5 mm is used. The shape of the glass layer 32 is a shape indicated by a dotted line in FIG. 4, and is a size obtained by subtracting the thickness 34d (see FIG. 4) of the adhesive layer 34 from the outer dimension of the metal layer. As the adhesive layer 34, the same sealing material as in the first embodiment is used, and is injected into a groove formed by the side surface of the glass layer 32 and the two metal layers 33x and 33y.

In the louver glass 31, the metal layers 33x and 33y sandwich the glass layer 32 from both sides (see FIG. 5) (see FIG. 5), and the total thickness of the two metal layers 33x and 33y and the glass layer 32 is approximately 6. It is formed so as to be in the range of 0.0 to 6.8 mm, and has a thickness suitable for the support bracket for 6 mm, and can be used for 100% compatibility in the conventional louver window. Further, both the function as a surface lattice fulfilled by the metal layer positioned on the outside and the original function fulfilled by the laminated glass portion are substantially simplified by simple calculation as compared with the louver glass 11 made of laminated glass having a single structure in Example 1. Since it is reinforced twice, it has a large resistance to bending and is not pulled out of the support bracket, so that it is strongly prevented from being cut off. Moreover, the location which has become a structure of a laminated glass is a part, and most glass layers are the area | regions of a non-laminated glass, and the single plate glass of thickness 3-5mm occupies, The conventional thickness 6.0-6 It is lighter than 8mm. Further, sufficient lighting can be obtained from the non-laminated glass region. Further, the laminated glass portion further enhances the horizontal stripe pattern of the louver window and is excellent in aesthetic appearance.

As a modification of Example 3, instead of any one of the metal layers, a flanged metal layer provided around the side surface of the glass layer is used as one metal layer, and the contact side or the non-contact side is provided. It can be set as the laminated glass of the double structure which two surfaces of any one side and a side surface consist of a metal layer. If either one of the two metal layers is omitted, it is in the category of single-layer laminated glass.

  A fourth embodiment of the present invention is an embodiment corresponding to claims 1 and 4, and FIG. 6 is a perspective view of the louver glass 41 according to the fourth embodiment of the present invention as viewed from the outdoor side. The laminated glass part 45 in Example 4 is a case where a metal layer is added to the side surface Z of the laminated glass part 15 in Example 1 (see FIG. 1) and is formed as a two-dimensional wall surface. The contact side X when the glass 41 contacts the armor shape is composed of the glass layer 42, the anti-contact side Y and the side surface Z are composed of the metal layer 43, and a set of one glass layer and two metal layers. It is made of laminated glass having a so-called double structure. When the louver glass 41 contacts the armor shape, the glass layers are in contact with each other as in the case of the first embodiment (see FIG. 2). In addition, the laminated glass part can also be provided partially extending on the short side, and in that case, it can be substituted by a spacer made of a plate-like metal, rubber or the like.

  The metal layer 33 constituting the non-contact side Y and the side surface Z of the laminated glass portion 45 has a two-dimensional cross section and is L-shaped, and is formed of an aluminum extruded shape, a stainless steel plate, a brass plate, or the like. Preferably, the short side is about 3 to 8 mm, the long side is about 5 to 30 mm, and the thickness is about 0.5 to 2 mm. Note that the L-shaped corner portion does not have to be a right angle and may have other shapes such as a semi-cylindrical shape as long as the shape follows two surfaces. As the adhesive layer 44, the same sealing material as in the first embodiment can be used. As the glass layer 42, colorless or colored template glass or float glass having a thickness of 3 to 5 mm can be used. Even if the adhesive layer interposed between the metal layer on the side surface Z and the glass layer 42 is omitted, the crime prevention function is not hindered. The metal layer on the side surface where the adhesive layer is omitted is made of glass. Since it functions as a cover material (plane lattice) that covers the side surfaces of the layer and does not constitute a laminated glass portion, it is in the category of single-layer laminated glass in that case.

The louver glass 41 is the same as the louver glass 11 of the first embodiment in terms of thickness, and the total thickness of the metal layer 43, the adhesive layer 44 and the glass layer 42 is formed to a thickness suitable for the 6 mm support fitting. The conventional louver window can be used with 100% compatibility. Moreover, since the laminated glass part 45 has a double structure in the louver glass 41, both the function as a surface lattice performed by the metal layer 43 and the original function performed by the laminated glass part 45 are the single structure of the first embodiment. Compared with the louver glass 11 of the present invention, it is strengthened approximately twice by simple calculation, does not bend, and is not pulled out from the support metal fitting, so that the breakage damage is prevented more strongly. Moreover, the location which has become a structure of a laminated glass is a part, and most glass layers are the area | regions of a non-laminated glass, and the single plate glass of thickness 3-5mm occupies, The conventional thickness 6.0-6 It is lighter than 8mm. Further, sufficient lighting can be obtained from the non-laminated glass region. Further, the laminated glass portion further enhances the horizontal stripe pattern of the louver window and is excellent in aesthetic appearance.

The fifth embodiment of the present invention is an embodiment corresponding to claims 1, 4 and 6, and FIG. 7 is a front view of the louver glass 51 according to the fifth embodiment of the present invention viewed from the outdoor side. is there. The laminated glass portion 55 in the fifth embodiment is a case where the laminated glass portion 45 in the fourth embodiment (see FIG. 6) is formed only on the exposed portion 52b, and is formed on the support fitting mounting portions 52a and 52a. It has not been. In the louver glass 51, the laminated glass portion 55 is formed only in the exposed portion 52b, so that the thickness does not increase in the support fitting mounting portions 52a and 52a, and the original thickness is maintained. Even louvered glass made of laminated glass using 0 to 6.8 mm plate glass can be used for 100% compatibility in louver windows equipped with 6 mm support fittings. That is, in the louver glass 41 of Example 4, the thickness of the louver glass 41 is increased by forming a laminated glass portion 45 on a 3 to 5 mm thick plate glass, while the louver glass 41 of Example 5 is adapted to the support bracket for 6 mm. In 51, the laminated glass portion 55 is limited to the exposed portion 52b so that the thickness of the support fitting mounting portion is not increased, and louver glass using plate glass of 6.0 to 6.8 mm is used as the support fitting for 6 mm. It is adapted and has the highest glass strength as a louver glass suitable for a support bracket for 6 mm.

In the louver glass 51, a plate glass having a thickness of 6.0 to 6.8 mm is used, and the glass strength is not only the highest limit for a 6 mm support bracket, but also directly exposed to attacks from intruders such as thieves. The portion 52b is a double-structured laminated glass, and has a surface lattice function and a laminated glass function that are approximately twice as simple as those of the single-structure louver glass 11 of Example 1, and bends. Since it is not removed from the support bracket, the damage caused by cutting is further prevented.

Embodiment 6 of the present invention is an embodiment corresponding to claims 1 and 5, and FIG. 8 is a perspective view of a louver glass 61 according to embodiment 6 of the present invention. The laminated glass portion 65 in the sixth embodiment is formed as a three-dimensional wall surface by adding a metal layer to the contact side X and the side surface Z of the laminated glass portion 15 in the first embodiment (see FIG. 1). In the case where a metal layer is added to the contact side X of the laminated glass portion 45 in FIG. 6 to form a three-dimensional wall surface, the contact side when the louver glass 41 contacts the armor shape X, anti-contact side Y, and side surface Z are both made of metal layer 63, and glass layer 62 is surrounded by metal layers of contact side X, anti-contact side Y, and side surface Z. One glass layer and three metals It is a combination with layers and is made of a so-called triple structure laminated glass. In the louver glass 61, the contact side X and the non-contact side Y are made of a metal layer, so that when the louver glass 61 comes in contact with the armor, the metal layers are in contact with each other. In addition, the laminated glass part 65 can be partially provided by extending also to the short side, and in that case, a spacer made of a plate-like metal, rubber, or the like can be used instead.

In the louver glass 61, the metal layer 63 has a three-dimensional cross section and has a groove shape, and is formed of an aluminum extruded shape or a molded product of a stainless steel plate or a brass plate, and the depth of the groove is about 5 to 30 mm. The outer dimension of the groove width is preferably about 5 to 8 mm, and the thickness of the material is preferably about 0.5 to 2 mm. In general, since the support bracket has a structure in which the vicinity of the long side on the contact side is missing, a slight over-thickness in the vicinity of the long side does not interfere with the mounting, and even if the outer dimension of the groove width is 8 mm. It can be attached to a 6 mm support bracket. As the adhesive layer 64, the same sealing material as in Example 1 can be used, and as the glass layer 62, colorless or colored template glass, stained glass, float glass or the like having a thickness of 3 to 5 mm can be used. . Note that even if the adhesive layer interposed between the metal layer on the anti-contact side Y and the side surface Z and the glass layer 42 is omitted, the crime prevention function is not hindered. Since it functions as a cover material (plane lattice) that covers the portion and does not constitute a laminated glass portion, in that case, it becomes a category of laminated glass having a single structure.

The louver glass 61 is formed such that the total thickness of the metal layer on the contact side X, the adhesive layer, the glass layer 62, the metal layer on the non-contact side Y, and the adhesive layer is suitable for the support bracket for 6 mm, It can be used for 100% compatibility in conventional louver windows. Further, since the louver glass 61 has a triple structure of the laminated glass portion 65, both the function as the surface lattice that the metal layer 63 fulfills and the original function that the laminated glass portion 65 fulfills are the single in the first embodiment. Compared to the louver glass of the structure, it is strengthened by a simple calculation by about 3 times, it is not bent and it is not pulled out from the support metal fitting, so that the breakage damage is prevented more strongly. Moreover, the location which has become a structure of a laminated glass is a part, and most glass layers are the area | regions of a non-laminated glass, and the single plate glass of thickness 3-5mm occupies, The conventional thickness 6.0-6 It is lighter than 8mm. Further, sufficient lighting can be obtained from the non-laminated glass region. Further, the laminated glass portion further enhances the horizontal stripe pattern of the louver window and is excellent in aesthetic appearance. In addition, the surface of the metal layer in contact with the armor shape is smooth, and the airtightness is not hindered by the uneven surface of the template as in the case of using the template glass. Even when an authentic stained glass connected by (Came) is used, the airtightness is not hindered and the surface strength is not lowered.

As a modification according to claims 1, 5, and 6, the laminated glass portion 65 can be formed only on the exposed portion so that the supporting metal mounting portion on the side opposite to the contact side can be cut off. In that case, the thickness of the glass layer can be increased by the thickness of the excised metal layer.

Example 7 of the present invention is an example corresponding to claim 7, and FIG. 9 is a plan view of a louver glass 51R according to Example 7 of the present invention, showing a state in which the lock mechanism R is released. FIG. 10 shows a state where the lock mechanism R is locked in FIG. The louver glass 51R according to the seventh embodiment has a configuration in which the lock mechanism R is provided on the louver glass 51 according to the fifth embodiment shown in FIG. 7, and is used exclusively for the clip-mounted louver window. Windows are not covered. Note that the louver glass 51R shown in FIG. 10 is a front view when viewed from the indoor side, whereas the louver glass 51 shown in FIG. 7 is a front view when viewed from the outdoor side.

  The lock mechanism R is provided with plates R1 at both ends of the metal layer 53 of the laminated glass portion 55, a tongue piece R2 (see FIG. 10) at one end of the plate R1, and a fixing screw at the other end. R3 is provided, and a substantially intermediate position between the tongue piece R2 and the screw R3 is pivotally supported on the metal layer 53 by a rivet R4. When the louver glass 51R is attached to the support fitting K, as shown in FIG. 9, the plate R1 is at a position substantially perpendicular to the louver glass 51R and is released, and the support fitting K is hooked to the clip portion. The stop piece K2 is opened in the direction of the arrow K3, and is inserted and mounted in a conventional manner. When locking the locking mechanism R, when the plate R1 is rotated in the direction of the arrow R5, as shown in FIG. 10, the tongue piece R2 is placed on the track when the clip portion K1 (the latching piece K2) is opened and closed. Appears and reaches a position where the movement of the clip portion K1 (the hooking piece K2) is blocked. Thereafter, the screw R3 is screwed into the metal layer 53 and fixed so that the plate R1 does not rotate. When releasing the lock, the reverse process is performed. The plate R1 is configured to rotate in the illustrated example, but other configurations such as sliding may be used.

  Since the lock mechanism R is provided independently on the louver glass, even in a louver window that does not have a lock function, such as a clip-mounted louver window, the lock function R can be obtained simply by replacing the conventional louver glass with the louver glass 51R of the present invention. Is provided. This locking mechanism prevents damage from being removed, and the laminated glass portion 53 prevents damage from being cut off at the same time.
