The frit layer 17 is configured by dispersing inorganic powder (typically glass powder) having a relatively high melting point, and as a result, other portions of the window plate 10, that is, the surface (vehicle exterior) 10A and the frit layer. The surface is rougher than the back surface 10B of the portion where 17 is not formed. The frit layer 17 is colored and opaque and is typically colored black. That is, the frit layer 17 has a function of shielding the back side of the outer peripheral portion of the window plate 10 when viewed from the surface of the window assembly 10.

As shown in FIG. 2, a double-sided pressure-sensitive adhesive tape adhered to the joined portion (concave groove portion) 28 of the strip material 20 on the joined portion 17A defined within the range of the frit layer 17 on the back surface 10B side of the window plate 10. The pressure-sensitive adhesive layer (that is, the separator 32A is previously peeled off) 32 facing the window plate 10 side of the window plate 32 is brought into contact and further pressed to apply a bonded portion 17A in the frit layer 17 of the window plate 10. And the joining portion 28 of the strip material 20 can be easily and reliably joined. At this time, the protruding height of the ridge portion 22 does not exceed the thickness of the double-sided pressure-sensitive adhesive tape 32, so that the joining is not hindered.
Further, as shown in the drawing, an opaque frit layer 17 is formed along the outer peripheral edges 13, 14, 15, 16 so as to have a width exceeding the width of the joint portion (concave groove portion) 28 of the strip members 20, 40, 50. Yes. As a result, the strip materials 20, 40, 50 joined to the back surface 10B side of the window plate 10 are shielded by the opaque frit layer 17, so that the strip materials 20, 40, 50 are not visually recognized from the front surface 10A side of the window plate 10. . Therefore, the window assembly 10 excellent in appearance and excellent in appearance can be obtained.
As described above, in this embodiment, the strip materials 20, 40, and 50 are placed on the back surface 10B side of the window plate 10 at a total of three locations along the outer peripheral edge (upper edge portion 13, left edge portion 14, and right edge portion 16). It is joined.

The strip assembly 5 in which a total of three strip members 20, 40, 50, which form a gate shape along the outer peripheral edge (the upper edge portion 13, the left edge portion 14, the right edge portion 16), is the back surface of the window plate 10. The window assembly 10 joined to the 10B side is fitted into a predetermined front window frame part (concave part) 4 and attached.
That is, as shown in FIG. 2, the shielding lips 24, 44, 54 abut against the side panel member 3 of the vehicle body panel 2 when mounted and in use, and are elastically deformed so as to be indicated by a two-dot chain line in FIG. Next, the side panel member 3 is elastically pressed. Thereby, the clearance gap between the outer periphery of the window board 10 and the vehicle body panel 2 (in the figure side panel member 3) of the front window frame part 4 is shielded. At this time, a paste-like sealant 7 is preliminarily discharged over the entire periphery of the window plate 10 on the back surface 10B side (frit layer 17 forming portion) of the window plate 10 in a portion corresponding to the gap with the bottom flange portion 6. In addition, a dam rubber 8 for preventing the sealant 7 from protruding is provided over the entire periphery of the window plate 10. The sealant 7 is a material that functions as an adhesive that exhibits rubber-like elasticity when cured. For example, those made of urethane resin are preferable. As a result, the window assembly 10 (window plate 10) is attached (fixed) to the predetermined front window frame portion (recessed portion) 4 and attached.

Next, the strip intermediate material 20A as the pre-strip material of the strip material 20 according to the present embodiment will be described in detail.
As shown in FIG. 6, the strip intermediate member 20 </ b> A according to the present embodiment extends laterally (that is, the shielding lip 24 extends) from the protruding strip portion 22 in the strip member main body portion 21 of the final form that becomes a part of the window assembly 1. The positioning reference piece 60 extends in the same direction as the direction). The positioning reference piece 60 has a higher hardness than the above-described polymer material forming the main body 21 (for example, durometer hardness according to JIS K7215 is HDA 90 or more), has excellent self-shaping force, and has a small elongation at break. It can be suitably molded using a thermoplastic elastomer (TPO, TPS, etc.). As will be described later, the positioning reference piece 60 is removed when the window assembly 1 is completed. Accordingly, it is preferable from the economical and environmental point of view that the material for molding the positioning reference piece 60 is recovered and reused after being removed, or the crushed material for disposal of other members is used. In addition, the main-body part 21 and the positioning reference | standard piece 60 can be integrated by welding in the boundary part at the time of coextrusion molding by selecting and using the material which has compatibility. As shown in the figure, the positioning reference piece 60 has a substantially U-shaped cross section. Specifically, the lower piece 63 protruding from the convex portion 22 of the main body 21, the side piece 64 extending from the lower piece 63 in a direction that bends at a substantially right angle, and the lower piece 63 bent at a further right angle from the side piece 64, It has the upper piece 66 extended in a substantially parallel direction, and the guide piece 68 extended toward the outward a little from the front-end | tip of this upper piece 66 (namely, the direction away from the main-body part 21).
A part of the lower piece 63 has a perforated connection portion 61 (that is, a separation portion 62A and a non-separation portion 62B (in the present embodiment, at a predetermined interval) by a disk-shaped cutter 154 of the connection portion forming apparatus 150 described later. 3) and the easy-to-bend portions 62) formed at a plurality of locations along the longitudinal direction. Preferably, the connecting portion 61 is arranged on the outside of the window plate 10 so that the positioning reference piece 60 is not visually recognized from the front surface side 10A of the window plate 10 when the positioning reference piece 60 is locked to the outer peripheral edge of the window plate 10 as described later. It is formed so as to be disposed at a position retracted by a predetermined dimension m from the peripheral end face toward the center P side of the window plate 10.

The dimension W between the lower piece 63 and the upper piece 66 (that is, the dimension of the side piece 64) is designed to be the same as or slightly larger than the thickness of the window plate 10 (that is, less than the thickness of the window plate 10). Absent.). Thereby, as will be described later, the positioning reference piece 60 can be easily locked to the outer edge (end surface) of the window plate 10. That is, as shown in FIG. 11 and the like which will be described later, the upper piece 66 is locked to the surface 10A along the outer peripheral edge of the window plate 10, the side piece 64 is locked to the end face 10C, and the back face 10B is The lower piece 63 has a cross-sectional shape that can be locked, and each of the pieces 63, 64, 66 constitutes a locking portion 60 </ b> A according to the present embodiment having a substantially U-shaped cross section.
Further, since the guide piece 68 extending from the tip of the upper piece 66 so as to open slightly outward is formed in the positioning reference piece 60, the engaging portion 60A is fitted into the edge of the window plate 10 to When the intermediate member 20 </ b> A is temporarily arranged on the window plate 10, the outer peripheral edge of the window plate 10 can be easily inserted into the locking portion 60 </ b> A while being guided by the guide piece 68.
Further, a protrusion 65 is formed and fitted into the intermediate film 11 </ b> C at a position corresponding to the intermediate film 11 </ b> C of the window plate 10 at a substantially central portion of the side piece 64. By providing such a protrusion 65, it is possible to further prevent positional deviation during temporary placement (typically temporary fixing) on the window plate 10.

  Next, a manufacturing method of the strip intermediate member 20A having the above shape will be described. The strip intermediate material 20A described above can be easily manufactured using, for example, an extrusion molding apparatus 100 as schematically shown in FIG. The illustrated extrusion molding apparatus 100 roughly includes a core material uncoiler 110 that continuously supplies the core material 30 to the extrusion die 142, and an adhesive that applies a predetermined adhesive to the surface of the core material 30. An applicator 120, an adhesive baking machine 130 for baking the applied adhesive, an extrusion die 142 having an orifice 143 with a predetermined opening shape, and an easily bendable portion at the connecting portion 61 of the extruded strip intermediate material 20A 62, an easy-to-bend portion forming device 150 for forming 62, a cooler 160, a take-up machine 170, and a cutting machine 180 for cutting to a predetermined length.

By using the extrusion molding apparatus 100 having such a configuration, the strip intermediate material 20A according to the present embodiment can be suitably manufactured by extrusion molding. Specifically, the core material 30 wound in a hoop shape is pulled out from the core material uncoiler 110 and continuously supplied to the extrusion die (die) 142. At this time, a predetermined adhesive is applied to the surface of the drawn core member 30 by the adhesive applicator 120. The applied adhesive is baked by an adhesive baking machine (built-in heater) 130 disposed on the downstream side of the adhesive application machine 120. The core material 30 thus surface-treated is then supplied to the die interior 144 of the extrusion die 142.
On the other hand, the molten molding material heated from a resin molding material supply unit of an extruder (not shown) is supplied to the inside 144 of the extrusion die 142 via the resin material supply path 141. And the resin molding is continuously extruded from the orifice 143 of the opening shape corresponding to the cross-sectional shape of 20 A of strip intermediate materials which concern on this embodiment with the core material 30. FIG. The configuration and operation mode of the extrusion die 142 are the same as those of a general extrusion die 142, and thus detailed description thereof is omitted. Although only one resin material supply path 141 is shown in FIG. 7, the strip intermediate material 20A according to the present embodiment is divided into two or more different molding materials (for example, a material for molding the main body 21 and a shielding lip). 24 and / or positioning reference piece 60 are molded with resin materials different from each other), when coextrusion (two-color molding) is performed, a resin material supply path corresponding to each molding material is provided. Multiple extruders are used.

The resin molded body extruded from the orifice 143 of the extrusion molding die 142 (that is, the long material to be the strip intermediate material 20A) is supplied to the foldable portion forming apparatus 150 according to the present embodiment.
As shown in FIG. 8, the bendable part forming device 150 includes a support base 152 that supports the strip intermediate member 20 </ b> A extruded from the orifice 143, and a disc that forms a blade part 156 having a sharp edge at the circumference. And a shape cutter 154. As shown in FIGS. 8 and 9, the center shaft 158 supported by the bearing portion 159 provided on the outer wall portion on the orifice side of the extrusion die 142 is fitted into the center hole 155 of the disk cutter 154. Yes. The rotating shaft 158 is preferably rotatable, but may be connected to a low-speed motor (not shown). Thereby, the disc-shaped cutter 154 can be rotatably supported at a predetermined position so that the rotation direction of the blade portion 156 coincides with the extrusion direction (that is, the longitudinal direction) of the strip intermediate member 20A. The bearing portion 159 has a compression spring (not shown) or the like to absorb mounting errors with the support base 152, errors due to wear of the disk cutter 154, and displacement due to vibration during operation. It is preferable to support in a state of pressing downward. Thereby, the disk-shaped cutter 154 can be operated accurately and stably.

As shown in FIG. 9, the blade portion 156 of the disk-shaped cutter 154 according to the present embodiment includes a sharp edge portion 156A having a predetermined circumferential length and a peripheral edge with a predetermined interval in the circumferential direction of the blade edge portion 156A. It has the recessed part 156B (cut-hole-shaped recessed part which retreats to radial inside) provided in at least one place.
The disc-shaped cutter 154 rotates at the same peripheral speed as the extrusion speed of the resin molded body, and the strip intermediate member 20A (long material) is moved downstream on the support base 152 by the rotating blade edge portion 156A. A part of the lower piece 63 of the positioning reference piece 60 (that is, the connecting portion 61) is cut in the longitudinal direction by the circumferential length of the blade edge portion 156A to separate the positioning reference piece 60 from the main body 21.
A V-shaped guide groove 153 having a depth α substantially the same as the shape of the blade edge portion 156A is formed on the support base 152. This prevents the outer peripheral edge (blade portion 156) of the disc-shaped cutter 154 from being displaced in the axial direction (left-right direction in FIG. 10), and the lower piece 63 of the positioning reference piece 60 at the desired accurate position. A part of (i.e., the connecting portion 61) can be cut, that is, a cut can be made.
Here, as described above, the blade portion 156 is provided with the recesses 156B at predetermined intervals. In the present embodiment, the depth d of the recess 156B is set to a depth that does not completely cut a part of the lower piece 63 (that is, the connecting portion 61). That is, as is apparent from FIG. 10, the bottom portion of the recess 156B is separated from the surface of the support base 152 in a state where the tip of the blade edge portion 156A enters the guide groove 153 and is in contact with the bottom of the groove. Since it is formed, a non-separating part is formed in which the connecting part 61 is left with a thickness of (d−α). As a result, it is possible to form the separation portion 62A cut by the cutting edge portion 156A and the non-separation portion 62B not cut by the recess portion 156B in the connecting portion 61. Further, when the number of the concave portions 156B provided in the blade portion 156 is increased, the interval of the length L between the concave portions 156B is narrowed, and the bendable portion 62 having a large number of non-separating portions 62B in the longitudinal direction is formed.
By providing the disk-shaped cutter 154 in this manner, the easy-to-bend portions 62 in which the separating portions 62A and the non-separating portions 62B (see FIG. 3) are alternately formed at predetermined intervals along the longitudinal direction can be used as the strip intermediate material. It can be easily formed in part of the 20A extrusion process. In addition, the depth of the recess 156B is set so that the thickness (that is, d−α) of the non-separating portion 62B connected by the thin wall is 0.01 to 0.5 mm (more preferably 0.05 to 0.1 mm). It is preferable to set the length d.
In addition, in the separation part 62A cut by the blade edge part 156A, shavings on the cut surface are generated as the surplus part 69. In order to prevent the surplus portion 69 from remaining in a position (that is, the strip main body portion 21) that can be seen from the exterior after being mounted on the window plate 10, the blade edge portion 156A of the blade portion 156 has the slope side disposed on the positioning reference piece 60 side. The surplus portion can be generated on the positioning reference piece 60 side. In addition, when forming the bending easy part 62 by the thin part by a ditch | groove, it can form by changing the shape of the orifice 143 of the extrusion die 142. FIG. That is, the extrusion die 142 can be protruded at a part of the connecting portion, and the orifice can be formed to reduce the gap.

Next, as shown in FIG. 7, the strip intermediate material 20 </ b> A (long material) having the bendable portion 62 formed in the connecting portion 61 is sent to a cooler 160 including a cooling tank containing a cooling medium and cooled. Then, after being solidified, it is taken through the take-up machine 170 and cut into a predetermined length by a cutting machine 180 having a cutting blade 182. By such a series of processes, a strip intermediate member 20A having a desired length is obtained.
As is obvious from the above description, the easy-to-bend portion 62 may be formed before the strip intermediate member 20A having a desired length is finally manufactured, and the connecting portion forming apparatus 150 is illustrated. Although it is preferable to perform molding when the material is still in a softened state by being disposed at a position adjacent to the extrusion die 142 to be formed, it is not always necessary to be at the position. For example, as shown by a two-dot chain line in FIG. 7, the connecting portion forming device 150 may be arranged on the downstream side of the cooler 160 or the take-up device 170, or after the strip intermediate member 20A is cut to a predetermined length. The folding easy part 62 may be formed in a separate process.

Next, a procedure for temporarily fixing the strip intermediate member 20A to a predetermined position (joined portion 17A) of the window plate 10 and joining the strip intermediate member 20A to an accurate position will be described.
First, extrusion molding is performed as described above, and cutting into desired lengths (here, lengths suitable for the three types of strip intermediate members 20A, 40A, and 50A respectively attached to the edge portions 13 and 1416 of the window plate 10). To do. Here, as shown in FIGS. 1, 3, and 4 (FIGS. 3 and 4 show the strip intermediate members 20A, 40A before the positioning reference piece 60, which will be described later, is removed from the main bodies 21, 41 by breaking or the like. That is, the strip material before removing the positioning reference piece 60 is referred to as the strip intermediate material 20A, 40A, 50A, and the strip material after removing the positioning reference piece 60 is the strip material 20. , 40, 50), the corners 18A, 18B on both sides of the upper edge 13 of the window plate 10, that is, both the upper edge strip intermediate member 40A and the left edge strip intermediate member 20A are adjacent to each other. The end portions of the strip intermediate members 20A and 40A and the intermediate portions of both strips in which the upper edge strip intermediate member 40A and the right edge strip intermediate member 50A are adjacent to each other. In the end portions of 50A and 40A, both ends of the upper edge strip intermediate member 40A and the left edge strip intermediate member 20A and the right edge strip intermediate member 50A are provided so that the adjacent strip intermediate members do not overlap each other. The upper end of each is cut and removed in advance by a predetermined length at a predetermined crossing angle.
Specifically, when the crossing angle at the corner portions 18A and 18B on both sides of the upper edge portion 13 of the window plate 10 is θ, the cut is 90 ° perpendicular to the major axis direction (long side) of each strip intermediate material. Cutting is performed obliquely so that the crossing angle (cutting angle) smaller than the surface is half the inner angle θ (0.5 × θ).
Then, the ends of two adjacent strip intermediate members (that is, the upper edge strip intermediate member 40A and the left edge strip intermediate member 20A, and the upper edge strip intermediate member 40A and the right edge strip intermediate member 50A) (Ie, the cut surfaces cut at (0.5 × θ)) are joined by welding or the like. In this way, in order to temporarily fix the outer edge portions 13, 14, and 16 of the window plate 10, the gate-shaped strip intermediate member assembly 5A in which the strip intermediate members 20A, 40A, and 50A are joined to each other is formed in advance.
In order to form the strip intermediate member assembly 5A bonded in a gate shape, the end portion of the positioning reference piece 60 is also cut in the same manner as described above before joining the ends of the strip intermediate members 20A, 40A, 50A. It is preferable to remove them.

  In this case, as shown in FIG. 3, the strip intermediate members 20A, 40A, and 50A in the corner portions 18A and 18B are slanted at an angle (0.5 × θ) that is half the inner angle θ as described above. The shielding lips 24, 44, and 54 may be cut in a substantially arc shape as shown in the drawing. That is, when the window assembly 1 is mounted on the vehicle body panel 2, the shielding lips 24, 44, 54 abut against the side panel member 3 (FIG. 2) of the vehicle body panel 2 and elastically deform as shown in FIG. They are arranged in a state of being displaced toward the outside of the vehicle by a predetermined displacement amount n. Therefore, in order to prevent the overlapping (interference) due to the surplus portions in the longitudinal direction from occurring in the shielding lips 24, 44, 54 in the corner portions 18A, 18B, the corner portions 18A, 18B As shown in FIG. 4, the shielding lips are joined to each other in a state where the shielding lips are displaced by n in advance toward the vehicle outer side. When the strip intermediate material is disposed only at the upper edge portion 13 and only when disposed at the left edge portion 14 and the right edge portion 16, the above-described oblique cutting and arcuate cutting of the shielding lip are not necessarily required. .

In the following, a process of temporarily fixing the strip intermediate member assembly 5A joined in a gate shape to the window plate 10 will be described. Although the following description demonstrates the case where the strip intermediate material 20A part is temporarily fixed along the left edge part 14 of the window board 10 among the strip intermediate material assemblies 5A joined to the gate shape, other edge parts are demonstrated. The same applies when the strip intermediate members 40A and 50A are temporarily fixed along the lines 13 and 16.
A double-sided pressure-sensitive adhesive tape 32 including a separator (release paper) 32A and a tab tape 32B is attached in advance to a concave groove portion (joining portion) 28 of the main body portion 21 of the strip intermediate material 20A (FIG. 6).
Starting from the corner portion 18A of the strip intermediate member 20A, the locking portion 60A of the positioning reference piece 60 in the vicinity of the corner portion 18A is locked (temporarily fixed) to the outer edge portion (here, the left edge portion 14) of the window plate 10. ) Specifically, as shown in FIG. 11, the positioning reference piece 60 is pressed against the end face of the window plate 10 fixed in position while being guided by the guide piece 68, and the lower piece 63 and the side piece which are the locking portions 60 </ b> A. The outer edge portion (left edge portion) 14 of the window plate 10 is sandwiched by a substantially U-shaped enclosure formed by the upper piece 66 and the upper piece 66, and the strip intermediate member 20A is locked. That is, the outer edge (left edge) 14 of the window plate 10 is sandwiched so that the lower piece 63 is in contact with the back surface 10B of the window plate 10, the side piece 64 is in contact with the end surface 10C, and the upper piece 66 is in contact with the surface 10A. . The above procedure is continuously performed from the vicinity of the corner portion 18A along the left edge portion 14 toward the lower edge portion 15 side. Thereafter, as indicated by an arrow X in FIG. 11, the main body portion 21 of the strip intermediate member 20A is rotationally displaced from the end surface 10C side toward the back surface 10B side. Thereby, the main body 21 and the shielding lip 24 are retracted from a position between the pressing surface 215 of the pusher main body, which will be described later, and the window plate end surface 10C, and do not interfere when the pusher main body moves forward.

Next, a method for mounting (main fixing) the 20A portion of the strip intermediate member assembly 5A joined in a gate shape to the outer edge portion 14 of the window plate 10 will be described with reference to the drawings.
FIG. 11 schematically shows a strip intermediate material mounting apparatus 200 according to this embodiment. As shown in the drawing, the strip intermediate material attaching device 200 according to the present embodiment is roughly provided on a window plate support portion 204 formed on a gantry 202 and on the side of the window plate support portion 204. And a pusher device 210.
The window plate support portion 204 has a flat upper surface portion 206 on which the window plate 10 is placed, and the upper surface portion 206 prevents the window plate 10 from being scratched on the surface of the window plate 10. It is made of a soft material such as a softer felt (or cushion) or a rubber plate.

On the other hand, the pusher device 210 is attached to a fluid pressure cylinder (typically a pneumatic cylinder) 212 connected to an external cylinder drive source (not shown) and to the tip of a rod 213 of the fluid pressure cylinder 212 so as to be able to advance and retract. The main body 214 is formed.
The main body 214 is disposed at a position facing the end surface 10C of the outer peripheral edge (for example, the left edge portion 14) of the window plate 10 when the window plate 10 is placed on the window plate support 204. The length of the end face 10C is substantially the same. On the surface facing the end surface 10C, the end surface is formed flat so that the positioning reference piece 60 can be pressed against the end surface 10C of the window plate, and the longitudinal direction is formed in a shape corresponding to the outer peripheral edge of the window plate. A pressing surface 215 is formed. The main body 214 is preferably made of a material that is softer and slightly elastically deformable than the window plate 10 (for example, a hard rubber material or a hard urethane resin).
A locking piece 216 that protrudes in a direction parallel to the surface of the facing window plate 10 (window plate support portion 204) is formed at the lower end 215A of the pressing surface 215. As shown in the figure, the locking piece 216 has a tip portion 216A formed in a tapered shape, and a concave groove portion 216B is formed on the upper surface side between the protruding portion of the tip portion 216A and the trunk portion 216C. Is formed. The locking piece 216 is formed of an elastically deformable material (for example, an elastic rubber material).
As a result of such a configuration, by operating the fluid pressure cylinder 212, the pusher main body 214 can be moved forward and backward with respect to the end face 10C of the window plate 10 placed on the window plate support 204.
As for a portion of the strip intermediate material that is temporarily fixed to the corner portions 18A and 18B of the window plate 10, as shown in FIG. 3 described above, both strip intermediate materials adjacent to each other (for example, in FIG. 3). The intermediate members 40A constituting the upper edge strip member 40 and the intermediate members 20A constituting the left edge member 20A) are positioned so as not to interfere with each other. Since the end portion adjacent to is cut and removed by a predetermined length in advance, it does not hinder temporary fixing.

  In the state where the strip intermediate member 20A is locked (temporarily fixed) along the left edge portion 14 of the window plate 10 as described above, the fluid pressure cylinder 212 is operated to advance the pusher body 214. Then, as shown in FIG. 12, the pressing surface 215 is pressed against the side piece 64 with a predetermined pressure over the entire length of the positioning reference piece 60 (locking portion 60 </ b> A), and the side piece 64 is pressed against the end face of the window plate 10. Adhere to 10C. Further, when the pusher body 214 is moved forward, the distal end portion 216A of the elastically deformable locking piece 216 is pressed against the guide piece 68 to be deformed, and the deformed locking piece 216 gets over the guide piece 68, The guide piece 68 is accommodated in the engaging piece concave groove portion 216B, and the state where the engaging piece 216 is hooked on the guide piece 68 is maintained as shown in FIG.

By using the pusher device 210 as described above, the locking portion 60A of the strip intermediate member 20A can be locked (fixed) to the outer edge portion of the window plate 10 accurately and reliably. Further, since the locking piece 216 is hooked on the guide piece 68, the guide piece 68 is pulled in the pulling direction when the pusher body 214 is retracted as will be described later, and the positioning reference piece 60 is locked. Release can be performed easily.
At this time, in the strip intermediate member 20A, the dimension of the lower piece 63 extending from the side piece 64 locked to the end face 10C of the window plate 10 is constant over the entire length. Therefore, the dimension from the end face 10 </ b> C of the window plate 10 to the position of the main body portion 21 is kept constant over the entire length of the left edge portion 14.
Thus, by using the strip intermediate member 20A provided with the positioning reference piece 60 (locking portion 60A) according to the present embodiment, the joining position of the strip member 20 joined to the back surface 10B side of the window plate 10 is determined. It can be mounted while maintaining a predetermined reference position over the entire length.

Thus, after the strip intermediate member 20A is locked (fixed) at a predetermined position by the pusher device 210, the separator (release paper) 32A is peeled off from the strip intermediate member 20A before starting the joining operation. At this time, by grasping and pulling the tab tape 32B, the separator (release paper) 32A is easily and quickly peeled off to expose the pressure-sensitive adhesive layer 32 facing the window plate 12 side of the double-sided adhesive tape 32. .
Next, a double-sided adhesive tape (pressure-sensitive adhesive layer) 32 is brought into contact with the bonded portion 17A on the back surface 10B of the window plate 10, and a predetermined pressing force is applied to the vertical portion of the main body portion 21 using the operator himself or appropriate equipment. From the direction (the direction of arrow Y in FIG. 12), the entire length of the main body 21 is added. As a result, the joining of the strip intermediate member 20A to the window plate 10 is completed.

As described above, after the strip intermediate member assembly 5A joined in a gate shape at a predetermined position is joined to the back surface of the window plate 10, the positioning reference piece 60 that has become unnecessary is removed.
First, the fluid pressure cylinder 212 is operated, and the pusher body 214 is moved backward from the window plate 10 to a predetermined position. At this time, as described above, since the locking piece 216 is kept hooked on the guide piece 68, the guide piece 68 (that is, the positioning reference piece) hooked on the locking piece 216 as the pusher body 214 is retracted. Part 60) also moves in the retracting direction of the pusher body 214. Thereby, the positioning reference piece 60 is moved from the end face 10C of the window plate 10 to a predetermined position (that is, a position where the hooked state of the locking piece 216 and the guide piece 68 is released, for example, a position indicated by a dotted line in FIG. 13). Pulling away can be realized.

  Specifically, as shown in FIG. 13, as the pusher body 214 retreats, the positioning reference piece 60 that has been disengaged from the end face 10 </ b> C of the window plate 10 to the position indicated by the dotted line is gripped with a finger or the like. By pulling with a predetermined force in the direction of pulling away from the window plate 10 (direction of arrow Z in FIG. 13), the non-separating portion 62B in the connecting portion 61 where the perforation is formed is broken. The entire positioning reference piece 60 can be easily separated. Thereby, the mounting of the strip material 20 is completed. In this manner, the window plate in which the strip assembly 5 (strip members 20, 40, 50) is accurately bonded to the predetermined position on the back surface side 10B of the window plate can be mounted on the predetermined front window frame portion (recessed portion) 4. If the force required to break the non-separating portion 62B exceeds the adhesive force of the adhesive tape, or if there is a risk of unexpectedly displacing the position of the joined strip intermediate member 20A, it will be weak instead of pulling. You may isolate | separate the connection part 61 with another hot cutter etc. which heated in addition to tension | pulling.

For example, depending on the desired window assembly 1, the strip material may be joined along only one edge (eg, the upper edge 13) of the outer peripheral edge of the window plate, or the strip material may be attached to both sides ( In some cases, bonding is performed along only the outer peripheral edges of the left and right edge portions 14 and 16). The positioning reference piece 60 described above includes at least a side piece 64 that can be locked to the end surface 10C of the outer peripheral edge of the window plate 10 and a lower piece 63 that can be locked to the back surface 10B of the window plate. Even if the shape is formed in a substantially L-shape, the same locking effect as that of the positioning reference piece 60 having the substantially U-shaped locking portion 60A can be realized. Moreover, the positioning reference | standard piece part 60 which is not provided with the guide piece 68 may be sufficient.
Moreover, various accessories can be attached to the window assembly of the present invention according to the application and purpose. Instead of the adhesive tape, an adhesive layer formed on at least one of the bonding surface and the bonded surface may be used. In this case, the above-described ridge 22 is not necessary.
