The insertion port 12 is formed in an elongated shape along the annular frame 3. The desiccant chamber 11 is formed so as to protrude outside the region S covered with the glass plates 4a and 4b, and the insertion port 12 is located inside the region S covered with the glass plates 4a and 4b. It faces the gap space 7. Thus, since the desiccant chamber 11 is molded so as to protrude outside the region S covered with the glass plates 4a and 4b, the size of the glass plates 4a and 4b can be minimized. it can. Therefore, the yield of the glass plate on molding is good, and the transparent plate holding frame 1 is reduced in weight and easy to handle.

  The insertion opening 12 is provided with step portions 13 and 13 slightly lower than the inner peripheral surface 3a of the annular frame 3 at both end edges in the short direction, and inside the longitudinal end portions in the desiccant chamber 11. The side surfaces 11a and 11a are formed into parallel surfaces inclined to one side. In other words, it is inclined with respect to the bottom wall inner surface 11b. In addition, an air vent hole 14 communicating with the outside air is formed on the back end side of one inner side surface 11a. In the air vent hole 14, there is provided a locking recess 15 in which a long locking piece 20 described later is locked.

  The covering lid 16 fitted to the insertion opening 12 has a size that matches the insertion opening 12 and is curved along the inner peripheral surface 3 a of the annular frame 3. As shown in FIG. 5, the covering lid 16 has a band-like lid plate portion 17 in which the inner peripheral surface 3a and the upper surface 17a of the annular frame 3 are flush with each other or the upper surface 17a is slightly lower than the inner peripheral surface 3a.

Similarly, it includes a locking piece 20 protruding downward and having a locking claw 19 protruding from the outer surface of the lower end. The locking claw 19 of one locking piece 20 is locked to the locking recess 15. The locking piece 20 having a locking claw 19 protruding from the outer surface of the lower end is formed longer than the locking piece 18 having a bent portion 18a that bends outward at the lower end.

  At the lower edges on both sides in the short direction of the lid plate portion 17, step portions 21 and 21 are provided which are in contact with both step portions 13 and 13 of the insertion port 12 of the desiccant chamber 11. In addition, a plurality of vent holes 22 are provided in the lid plate portion 17 along the center line in the longitudinal direction. In addition, the one locking piece 20 and the other locking piece 18 are arranged in parallel at the same inclination angle similarly to the inner side surfaces 11a, 11a of the desiccant chamber 11.

  Examples of the desiccant 10 include silica gel (amorphous compound of silicon dioxide produced using water glass and sulfuric acid as raw materials) or molecular sieves (manufactured by chemical reaction of water glass, clay and caustic soda, metal, aluminum, silicon). And metal alumina silicate composed of oxygen), and these powders or granules are enclosed in a breathable bag.

  The transparent plate holding frame 1 according to the present invention has the above configuration, and the assembly order thereof will be described next. First, the bag-containing desiccant 10 is put into the desiccant chamber 11 from the insertion port 12. 6A and 6B, the long locking piece 20 is positioned on the air vent hole 14 side, the short locking piece 18 is inserted into the insertion port 12, and the long locking piece 20 is inserted into the insertion port 12. Insert into. Further, the bent portion 18a of the short locking piece 18 is fitted into the recessed portion 31 provided on the inner side surface 11a opposite thereto, and the locking claw 19 of the long locking piece 20 is fitted to the locking recess 15 of the air vent hole 14. To lock. At this time, the outer side surface of the long locking piece 20 comes into contact with the inner side surface 11a of the desiccant chamber 11 facing this, and the air vent hole 14 provided in the inner side surface 11a is closed by the locking piece 20. Strictly speaking, a very small gap 23 is formed between the leading edge of the locking piece 20 and the bottom wall inner surface 11 b of the desiccant chamber 11. Further, the step portions 21 and 21 on both lower surfaces of the lid plate portion 17 abut on the step portions 13 and 13 on both sides of the insertion port 12 so that the inner peripheral surface 3a of the annular frame 3 and the upper surface 17a of the cover plate portion 17 are connected. It will be the same. Thereby, the covering lid 16 cannot be easily removed. In addition, since the opposing inner side surfaces 11a and 11a of the desiccant chamber 11 are inclined and formed in parallel, the covering lid 16 is difficult to be removed from the desiccant chamber 11, and is formed by the locking claws 19 of the long locking pieces 20. Only one locking portion, that is, one locking concave portion 15 is required. The recessed portion 31 is set to a depth that does not cause a problem in molding.

  Next, the adhesive 24 is sufficiently applied to the glued surface portions 8a and 8b of the annular grooves 6a and 6b formed on the front surface and the rear surface of the annular frame 3, so that there is no gap. On the front and rear surfaces of the annular frame 3, as shown in FIG. 7A, the adhesive 24 is accumulated in each recess 9, and the adhesive 24 is accumulated in the recess 9. Then, the outer peripheral ends of the glass plates 4a and 4b are fitted into the annular grooves 6a and 6b from both the front and rear surfaces of the annular frame 3 and pressed against the glued surface portions 8a and 8b to be firmly bonded. Thereby, the crevice space 7 sealed between both glass plates 4a and 4b is fabricated.

  By the way, on the automated assembly line, the glass plates 4a and 4b are vertically lowered and bonded to the upper surface of the annular frame 3 from the upper surface side of the annular frame 3 arranged horizontally. It has become so. For this reason, when the second glass plate 4b is bonded and attached to the side surface of the annular frame 3, excess air instantaneously accumulates between the two glass plates 4a and 4b, and the second glass plate There is a risk of hindering the mounting of the plate 4b. However, along with the operation of attaching the glass plate 4b, the excess air is released to the outside air from the slight gap 23 between the bottom wall inner surface 11b of the desiccant chamber 11 and the long locking piece 20 through the air vent hole 14. The Therefore, there is no problem in attaching the glass plates 4a and 4b to both side surfaces of the annular frame 3.

  After the glass plates 4a and 4b are adhered and attached to both the front side and the rear side of the annular frame 3 in this way, the air vent hole 14 is filled with the adhesive 24 from the outside, and the air vent hole 14 is sealed. To do. As a result, the gap space 7 is completely sealed, and the desiccant chamber 11 and the gap space 7 communicate with each other through the air holes 22, and the inside of the gap space 7 is dried by the desiccant 10.

The long locking piece 20 of the cover lid 16 is locked to the locking recess 15 of the air vent hole 14, and the air vent hole 14 is filled with the adhesive 24. Therefore, it is no longer necessary to cover the insertion cover with the cover and apply the adhesive around it and attach it in a sealed manner as in the prior art. As a result, it is possible to omit the process of attaching and attaching only the covering lid 16 with the adhesive 24, simplifying the work process and improving the work efficiency. Moreover, the adhesion area is reduced correspondingly, and the sealing accuracy of the gap space 7 is also improved.

  In addition, since the locking recess 15 for locking the long locking piece 20 of the cover lid 16 is provided in the air vent hole 14, the air vent hole 14 has an original air vent function and is a mechanism for locking the locking piece 20. It also has a stopping function, and by filling the air vent hole 14 with the adhesive 24, the sealing and the locking piece 20, that is, the cover 16 can be fixed at the same time.

  The assembled transparent plate holding frame 1 is arranged at a predetermined position on the back side of the front frame A. Then, the plurality of hook members 30 provided at predetermined positions of the front frame A are rotated and engaged with the attachment pieces 5 and 5, and the transparent plate holding frame 1 is attached.

An air vent hole 29 communicating with the outside air is opened. Also in this case, since the desiccant chamber 26 is formed so as to protrude outside the region S covered with the glass plates 4a and 4b, the size of the glass plates 4a and 4b can be minimized. it can. Therefore, the yield of the molded glass plate is good, and the transparent plate holding frame 1 is reduced in weight and easy to handle.

  Then, as shown in FIG. 9A, the bag-like desiccant 10 is put into the desiccant chamber 26 from the insertion port 12 in the same manner as described above. Next, the locking pieces 28, 28 are inserted into the insertion port 12 with both the locking pieces 28, 28 facing down. The locking claw 19 of each locking piece 28 advances while being in contact with each opposing inner side surface 26 a of the desiccant chamber 26 and is locked to each locking recess 15. At this time, the outer side surfaces of both locking pieces 28, 28 come into contact with both inner side surfaces 26 a, 26 a of the desiccant chamber 26, and the air vent holes 29 provided on the inner side surfaces 26 a are closed by the respective locking pieces 28. Is done. Strictly speaking, a very small gap 23 is formed between the leading edge of each locking piece 28 and the bottom wall inner surface 26b of the desiccant chamber 26. Further, the stepped portions 21 on both lower surfaces of the lid plate portion 27 abut against the stepped portions 13 on both side edges of the insertion port 12 so that the inner peripheral surface 3a of the annular frame 3 and the upper surface 27a of the lid plate portion 27 are flush with each other. . Alternatively, the upper surface 27 a of the lid plate portion 27 may be slightly lower than the inner peripheral surface 3 a of the annular frame 3. This prevents the cover lid 25 from being easily removed.

  In another embodiment, the desiccant chamber 26 protrudes outside the region S covered with the glass plates 4a and 4b and the insertion port 12 is inside the region S covered with the glass plates 4a and 4b. Facing the clearance space 7, both the locking pieces 28, 28 of the cover lid 25 are locked to the locking recesses 15 of both the air vent holes 29, 29, and the air vent holes 29, 29 are filled with the adhesive 24. . Therefore, also in this case, it is possible to omit the process of attaching only the cover lid 25 by the adhesive 24, and the work process can be simplified and the work efficiency can be improved. Moreover, the adhesion area is reduced correspondingly, and the sealing accuracy of the gap space 7 is also improved.
