  Hereinafter, specific embodiments of a glass plate article holder and a glass plate article holding method according to the present invention will be described in detail with reference to the drawings.

  Further, in the present specification, terms such as “parallel” and “vertical” allow a deviation that does not impair the effects of the present invention. For example, an error of about ± 5 ° is allowed on the basis of the parallel and vertical positional relationship in a strict sense.

  Further, in the present application, the “glass plate article” is a concept including a glass plate or a glass plate with a molding. Further, the “tip portion of the glass plate article” refers to the end portion of the glass plate or the molding end portion of the glass plate with molding. Further, “breakage of the tip portion of the glass plate article” refers to breakage of the end portion of the glass plate, crushing or deformation of the molding, peeling of the adhesion between the glass plate and the molding, and the like.

  FIG. 1 is a schematic sectional view of a glass plate article holder, FIG. 2 is a first embodiment of a glass plate article, and FIG. 3 is a second embodiment of a glass plate article. An example of a glass plate article holder and glass plate clamping will be described with reference to FIGS.

  The glass plate article holder 1 of the present embodiment holds a glass plate 50 for a windshield for a vehicle, particularly an automobile, in a vertical posture. The first member 10, the second member 20, and the first member 10. And a support member 30 that supports the second member 20.

  The support member 30 includes a first guide 31 that has a U-shaped cross section and is inclined with a predetermined inclination angle θ with respect to a horizontal plane, and a second guide 32 that stands perpendicular to the horizontal plane. Yes. The inclination angle θ is preferably 40 degrees or more and 70 degrees or less, more preferably 45 degrees or more and 65 degrees or less, and further preferably 50 degrees or more and 60 degrees or less. Thereby, work, such as discharge | emission of a glass plate article | item, becomes favorable. In the case shown in FIG. 10, when the glass plate 50 is discharged, the glass plate 50 must first be lifted vertically. Moreover, if the inclination angle θ is within the above range, both high workability such as discharge of the glass plate 50 and sufficient clamping force to the glass plate 50 sandwiched between the first member 10 and the second member 20 are achieved. Can be provided. In the present embodiment, the inclined surface 33 of the first guide 31 is inclined linearly, but may be arcuate.

  The first member 10 is made of, for example, a urethane-based cushion material, and is supported so as to be slidable along the inclination direction of the first guide 31. The first guide 31 slides the first member 10 in a direction approaching the second member 20. Thereby, since the glass plate article can be held by the opposing surfaces of the first member 10 and the second member 20, it is difficult for the tip of the glass plate article to be loaded.

  Further, the first member 10 is slidable so as to approach the second member 20 from an oblique direction. As a result, even when the glass plate article is finally held on the opposing surface, the position of the first member 10 before holding the glass plate article can be arranged at a desired position, and space-saving glass plate article holding is possible. Can be used as a tool. Moreover, since it can take out in the diagonal direction in the case of discharge | emission operation | work of a glass plate article | item, discharge | emission operations etc. become favorable.

  The second member 20 is, for example, a roller that is fixed to the upper end portion of the second guide 32 and is rotatable in a circular cross section in the present embodiment. By using the second member 20 as a roller, friction between the glass plate article and the second member 20 at the time of carrying in or discharging the glass plate article can be suppressed, and the carrying-in or discharging operation becomes easy. Moreover, damage to the glass plate article due to friction can be prevented. The first member 10 includes a third member 11 that protrudes toward the second member 20 in the vicinity of the lower end of the first member 10. The 3rd member 11 supports the front-end | tip part of a glass plate article. Thereby, the front-end | tip part of a glass plate article | item can be protected. Moreover, in the glass plate article holding method to be described later, the first member 10 can be slid along with the insertion of the glass plate article. The first member 10 and the second member 20 are arranged so as to face each other with a predetermined distance therebetween.

  The first guide 31 includes an elastic member 40 that elastically connects the upper end of the first guide 31 and the upper end of the first member 10, and the glass plate 50 is not held by the glass plate article holder 1. The first member 10 is biased in the vicinity of the upper end of the first guide 31. Thereby, when the glass sheet article is discharged, a gap is formed between the first member 10 and the second member 20 at the stage of starting to lift the glass sheet article, so that the discharge operation is facilitated. The elastic member 40 is a constituent member that can be expanded and contracted along the first guide 31. In the embodiment, the elastic member 40 is a spring, but is not limited thereto.

  The glass plate article holder 1 of the present embodiment has a simple structure in which the slidable first member 10 is provided on the first guide 31 of the support member 30 and the second member 20 is fixed to the second guide 32. 50 is smoothly supported, inserted, and slid, and workability is improved.

  FIG. 2 shows a glass plate article holder 1 that holds a glass plate 50 that is a first embodiment of a glass plate article. The glass plate 50 is a laminated glass having a first surface 51 and a second surface 52. Yes, the glass plate 50 is clamped by bringing the first surface 51 into contact with the first member 10 and bringing the second surface 52 into contact with the second member 20.

  When the end surface 53 of the glass plate 50 is placed on the third member 11 of the first member 10, the first member 10 slides along the inclined surface 33 of the first guide 31 by the weight of the glass plate 50, and the glass plate 50 is moved. The first member 10 and the second member 20 can be sandwiched. 2 and 3, the glass plate article is sandwiched at two locations from the front and back sides, and only the reaction force of the elastic member 40 is applied to the tip portion of the glass plate article. Therefore, the support at the front end of the glass plate article is eliminated, the load on the front end is reduced, and breakage of the front end can be suppressed.

  FIG. 3 shows a second embodiment of the glass plate article, in which a resin molding 54 is formed on the end surface 53 of the glass plate 50. That is, the glass plate 50 and the resin molding 54 constitute a glass plate with a molding that is a glass plate article. The resin molding 54 is made of an elastic member and is attached by a bonding material such as a double-sided tape. In the second embodiment, the end surface 53 also includes a resin molding 54. In a state where the glass plate article is held by the glass plate article holder 1, the second member 20 is in contact with the surface of the resin molding 54, but indirectly supports the second surface 52 of the glass plate 50. Yes. Further, the end portion of the resin molding 54 is in light contact with the third member 11 and only the reaction force of the elastic member 40 is applied. Therefore, the load on the front end portion of the glass plate article is reduced, and also in the resin molding 54, fears such as crushing and deformation of the resin molding 54 and peeling of the adhesive between the glass plate 50 and the resin molding 54 are eliminated.

  3 to 6, the second member 20 (the first member 10 in FIG. 6B) is in contact with the resin molding 54 included in the glass plate article and indirectly the second surface of the glass plate 50. Although 52 (the 1st surface 51 of the glass plate 50 in FIG.6 (b)) is supported, it is not limited to this. That is, the second member 20 (the first member 10 in FIG. 6B) directly contacts the second surface 52 of the glass plate 50 (the first surface 51 of the glass plate 50 in FIG. 6B). The second surface 52 (the first surface 51 in FIG. 6B) may be supported.

And the above-mentioned glass plate 50 is manufactured by a well-known float method. In the float process, a molten glass substrate is floated on a molten metal such as tin, and a plate glass having a uniform thickness and plate width is formed by a strict temperature operation. As an example of the composition of the glass plate 50 used in this embodiment, the composition viewed in mole percent on the oxide basis, of _{SiO 2 50~80%, B 2 O} 3 of 0%, Al ₂ O ₃ of _{0.1~25%, Li 2 O + Na} 2 O + K 2 O 3-30% of MgO 0 to 25% 0 to 25% of CaO, 0 to 5% of SrO, and BaO 0 to 5 %, Glass containing 0 to 5% of ZrO ₂ and 0 to 5% of SnO ₂ is mentioned, but it is not particularly limited.

  FIG. 4 is a schematic cross-sectional view showing a method for holding the glass plate article holder 1 of the present embodiment. Based on FIG. 4, the operation of the glass plate article holder 1 will be described. Thereafter, the glass plate article of the embodiment is provided with the resin molding 54.
