International Publication No. 2007/123070

  However, in order to hold the glass plate by the above-described apparatus, two steps, a step of sandwiching the glass plate with the holder member and a step of inserting the holder member into the fixing member, must be performed. In addition, the holder member must be supported so that the holder member does not come off the glass plate, and there is a problem that the work for holding the glass plate in the apparatus is complicated. Furthermore, since the glass plate may be heavy, the glass plate may be damaged by impact when inserted into the fixing member. The present invention has been made to solve the above-described problems, and can hold a glass plate with a simple operation, and can reduce an impact when placing the glass plate. An object is to provide a holding tool.

   The present invention is a glass plate holder for holding a flat glass plate in a vertical posture, and can hold both the surfaces of the glass plate, support the clip, and move the clip in the vertical direction. And a support body having a guide portion, and an elastic member for biasing the clip upward.

  According to this structure, glass can be clamped only by arrange | positioning so that a glass plate may be pinched | interposed into a clip. Moreover, since the clip is supported by the support, if the glass plate is attached to the clip, the glass plate is supported by the support in a vertical posture. Therefore, unlike the conventional example, the glass plate can be held by a simple operation. Since the support has a guide portion that allows the clip to move in the vertical direction, the clip can move in the vertical direction, and the clip is biased upward by the elastic member. The impact when the glass plate is placed on the clip can be mitigated by the elastic member. Therefore, it is possible to prevent the glass plate from being damaged by an impact when the glass plate is placed. Note that the “vertical posture” in the present invention does not indicate perfect vertical, but allows a slight inclination.

  In the said glass plate holder, the said clip can be supported by the said support body so that a movement in the thickness direction of the said glass plate is possible. In this way, when the glass plate held by the glass plate holder receives a force in the thickness direction, the glass plate can move in the thickness direction, so that the impact due to the received force is reduced. Can do. As a result, it is possible to prevent the glass plate from being damaged.

  In the glass plate holder, the clip includes a first holding member having a first contact portion that contacts the glass plate from one surface, and a second contact portion that contacts the glass plate from the other surface. And a fulcrum portion that rotatably supports the first clamping member and the second clamping member, and the support body is configured so that the clip moves downward. In addition, it may be configured to have a pressing portion that presses at least one of the clamping members so that the interval between the first contact portion and the second contact portion is narrowed.

  If comprised in this way, by arrange | positioning a glass plate between the 1st clamping member and 2nd clamping member of a clip, a clip will move below with the weight of a glass plate, and the press part of a support body is according to it accordingly. The clip is pressed so as to reduce the distance between the first contact portion and the second contact portion of the clip. Thereby, a glass plate can be reliably hold | maintained to a holder with very simple operation.

  In the glass plate holder, the second holding member has a center of gravity on a surface side opposite to the first holding member, and when the clip moves upward, 1 It can comprise so that it may rotate away from a clamping member. If comprised in this way, when a clip is raising, since each clamping member is not pressed by a press part, a 2nd clamping member rotates so that it may leave | separate from a 1st clamping member by the effect | action of a gravity center. By doing in this way, it is possible to release the press only by lifting the glass plate upward, and the distance between both the holding members of the clip is widened, so that the glass plate can be easily detached from the holder. Further, when the clip is lifted, the gap between the both holding members is always widened, so that it is easy to insert the glass plate between the both holding members. Therefore, it becomes easy to attach the glass plate to the holder.

  The said glass plate holder WHEREIN: The said clip is provided with the engaging member, The said guide part is provided with the guide groove which the said engaging member engages so that a vertical movement is possible, The said engaging member The upward movement of the guide groove can be restricted by the upper end portion of the guide groove. Thereby, even if a clip is urged | biased upwards by an elastic member, it can prevent that a clip detaches | leaves from a support body.

  Moreover, the said glass plate holder WHEREIN: The said engaging member can be provided in the lower end part of the said clip, and the horizontal groove | channel extended in the thickness direction of the said glass plate can be connected with the lower end part of the said guide groove. In this way, the clip engaging member can move along the horizontal groove while the clip is moving downward. For example, when the glass plate held by the clip receives a force in the thickness direction, the glass Since the plate can move in the thickness direction, the impact caused by the received force can be reduced. As a result, it is possible to prevent the glass plate from being damaged.

  The said glass plate holder WHEREIN: The said glass plate can be used as the glass plate for motor vehicles. Since the glass plate can be easily held, it can be loaded without damaging a particularly large-sized windshield. Moreover, since it can be easily removed from the holder, it can be carried into an automated automobile production line while being held by the holder.

  In the glass plate holder, a molding is attached to at least a part of a peripheral portion of the glass plate, the clip has a support portion that supports the glass plate, and the support portion is the molding. Can be configured to support the edge of the glass attached. If it does in this way, as for the glass plate, the edge part of glass will be supported by the support surface of a clip. That is, the weight of the glass plate acts on the edge of the glass and does not act on the molding attached to the peripheral edge of the glass. Therefore, it is possible to prevent the molding from being damaged or deformed by receiving external force.

  Moreover, the glass plate conveying apparatus which concerns on this invention is equipped with at least one of the glass plate holders mentioned above.

<1. Glass plate with molding>
First, the glass plate which the glass plate holder which concerns on this embodiment makes object is demonstrated, referring FIG. FIG. 1 is a cross-sectional view of a glass plate. As shown in FIG. 1, the glass plate 1 is formed in a plate shape having a first surface 11 and a second surface 12, and is used for an automobile. A long molding 2 is attached to one peripheral edge of the glass plate 1. The molding 2 is used for mounting the glass plate 1 to an automobile. A plate-like bonding portion 21 bonded to the second surface 12 of the glass plate 1 and a glass plate from an end portion of the bonding portion 21. And a base portion 22 extending so as to cover one end edge portion 13. Further, in the base portion 22, the end portion on the side where the adhesive portion 21 is provided, that is, the end portion on the second surface 12 side of the glass plate 1, is formed in a U-shaped cross section and can be elastically deformed. 23 are connected. The opening 231 of the U-shaped mounting portion 23 faces the first surface 11 side of the glass plate 1 and engages with a mounted member of an automobile that is a mounting target.

<2. Glass plate holder>
Next, the glass plate holder will be described with reference to FIGS. 2 is a front view of the glass plate holder, FIG. 3 is a side view of FIG. 2, and FIG. 4 is a front view of the clip. As shown in FIGS. 2 to 4, the glass plate holder 3 includes a clip 4 that holds the glass plate 1 and a support 6 that supports the clip 4. A spring (elastic member) 5 is attached to the lower end of the clip 4, and the clip 4 is urged upward by the spring 5. Hereinafter, each member will be described.

<2.1 Clip>
As shown in FIG. 4, the clip 4 includes a first clamping member 41 that faces the first surface 11 of the glass plate 1 and a second clamping member 42 that faces the second surface 12 of the glass plate 1. . Both the sandwiching members 41 and 42 are formed in a rectangular plate shape, and a surface of the first sandwiching member 41 facing the second sandwiching member 42 constitutes a first sandwiching surface (first contact portion) 410, A surface of the two clamping members 42 facing the first clamping member 41 constitutes a second clamping surface (second contact portion) 420. That is, the glass plate 1 is sandwiched between the first sandwiching surface and the second sandwiching surface as will be described later. A cylindrical shaft fixing portion 411 extending in the horizontal direction along the edge of the first clamping member 41 is formed at the lower end portion of the first clamping member 41. The shaft fixing portion 411 includes a shaft body. The (engagement member) 43 is rotatably inserted (see FIGS. 2 and 3). The shaft 43 is engaged with the support 6 as will be described later.

  In the first clamping member 41, a shaft member (fulcrum portion) 412 extending in the horizontal direction along the first clamping surface 410 is attached above the shaft fixing portion 411. The shaft member 412 has a circular cross section and is attached to the first clamping surface 410 via a connecting portion 413 having a width smaller than the diameter thereof. A step portion (support portion) 414 extending in the horizontal direction is formed above the shaft member 412 in the first clamping surface 410. The upper end portion of the first clamping member 41 is curved outward in a direction away from the second clamping member 42.

  Next, the second clamping member 42 will be described. A fixing portion 421 having a U-shaped cross section that engages with the shaft member 412 of the first clamping member 41 is provided at the lower end of the second clamping member 42. More specifically, the fixing portion 421 is formed so that the U-shaped opening 4211 faces the first clamping member 41 side and extends in the horizontal direction. A shaft member 412 of the first clamping member is fitted into the fixed portion 421 so as to be rotatable about the axis. Thereby, both the clamping members 41 and 42 are rotatably connected to each other with the shaft member 412 as a fulcrum, and the distance between the both clamping members 41 and 42 opened upward can be widened or narrowed.

  Above the fixing portion 421 of the second clamping member 42, a bulging portion 423 that is formed thick and bulges toward the first clamping member 41 is formed. Thereby, a recessed part is formed between the fixing part 421 and the bulging part 423, and the attaching part 23 of the molding 2 is accommodated in the recessed part as will be described later. A cushion member 422 such as urethane is disposed below the concave portion and on the upper surface of the fixing portion 421, and acts as a buffer member for the molding 2 of the glass plate 1 sandwiched between the clips 4. In the bulging portion 423, the center of gravity of the second clamping member 42 is located on the surface side opposite to the first clamping member 41. Thereby, if the external force does not act, the 2nd clamping member 42 will rock | fluctuate so that it may space apart from the 1st clamping member 41 by the effect | action of a gravity center. The upper end portion of the second clamping member 42 is curved outward in a direction away from the first clamping member 41.

<2.2 Support>
Next, the support 6 will be described. As shown in FIGS. 2 and 3, the support 6 includes a substrate 61 that is formed in a rectangular shape and extends in the horizontal direction, and a pair of support plates 62 that stand from opposite sides of the substrate 61. . Each support plate 62 is formed in a trapezoidal shape, and a slit 621 is formed at the upper end. The slit 621 has an upper end opened upward and extends in the vertical direction. In the support plate 62, an elongated guide groove 622 extending in the vertical direction is formed below the slit 621. A horizontal groove 623 extending in the horizontal direction is formed at the lower end of the guide groove 622 and communicates with the guide groove 622. The guide groove 622 is engaged with both end portions of the shaft body 43 inserted through the shaft fixing portion 411 of the clip 4 described above. Therefore, the clip 4 moves up and down with respect to the support body 6 as the shaft body 43 moves up and down along the guide groove 622.

  As shown in FIG. 3, the spring 5 is disposed between the upper surface of the substrate 61 of the support 6 and the lower end of the clip 4. As a result, the clip 4 is biased upward. As described above, since the shaft body 43 attached to the clip 4 is engaged with the guide groove 622 of the support body 6, the shaft body 43 is guided. By contacting the upper end of the groove 622, the upward movement of the clip 4 is restricted.

  A pair of guide bars (pressing parts) 63 are respectively attached to both sides of the slit 621 formed in the support plate 62. Both guide bars 63 extend so as to connect the opposing support plates 62, and the clip 4 is disposed between the both guide bars 63. In the initial state where the glass plate 1 is not held, the guide bar 63 is adjusted to be disposed at a position slightly higher than the shaft member 412 of the clip 4. The clip 4 moves up and down between the guide bars 63, and both the clamping members 41 and 42 swing with each other.

<3 Glass plate holding method>
Next, a method for holding the glass plate 1 by the glass plate holder 3 configured as described above will be described with reference to FIGS. As shown in FIG. 2, when the glass plate 1 is not held, the clip 4 is urged upward by a spring 5. Since most of the clip 4 is disposed at a position higher than the guide bar 63, the second clamping member 42 is not subject to much restriction from the guide bar 63, and the first clamping member is operated by the center of gravity. It rotates so that it may space apart from 41, and the clearance gap between both the clamping members 41 and 42 is wide. Thereby, it becomes easy to insert the glass plate 1 between the both clamping members 41 and 42.

  Next, the edge portion 13 to which the molding 2 of the glass plate 1 is attached is directed downward, and the orientation is adjusted so that the first surface 11 of the glass plate 1 faces the first clamping member 41. Then, as shown in FIG. 5, the glass plate 1 is placed between both the sandwiching members 41, 42 so that the corner portion on the first surface 11 side of the edge portion 13 is placed on the step 414 of the first sandwiching member 41. Insert into. When the end edge portion 13 is placed on the step portion 414 of the first clamping member 41, the first clamping member 41 is pressed downward by the weight of the glass plate 1, whereby the clip 4 is lowered downward against the spring 5. To go. At this time, both the clamping members 41 and 42 move downward between the guide bars 63, but both the clamping members 41 and 42 can pass through the gap between the guide bars 63 as shown in FIG. 6. As described above, while being pressed by the guide bar 63, the guide bar 63 is moved downward to be narrowed so as to narrow the gap. Thereby, the glass plate 1 is pinched | interposed into both the clamping members 41 and 42, and is fixed. Then, as shown in FIG. 7, the clip 4 moves downward until the shaft body 43 contacts the lower end portion of the guide groove 622. In addition, since the slit 621 is formed in the support plate 62 of the support body 6, even if the glass plate 1 is longer than the distance between the support plates 62, the glass plate 1 is inserted through the slit 621. 6 will not interfere.

  Thus, when the clip 4 is disposed at the lowermost part, the vicinity of the upper end portions of the both clamping members 41 and 42 is pressed by the guide bar 63, the gap between them becomes narrow, and the glass plate 1 is firmly clamped. At this time, since the glass plate 1 is supported by the step portion 414 of the first clamping member 41, the mounting portion 23 of the molding 2 merely presses the cushion member 422 lightly, Is not supported. Therefore, in this embodiment, the glass plate 1 can be supported without applying a force to the attachment portion 23. Therefore, it is possible to prevent the attachment portion 23 from being deformed by an external force.

  In this state, when a force in the thickness direction is applied to the glass plate 1, the clip 4 swings in the horizontal direction as shown in FIG. For example, as shown in FIG. 8A, when a force F <b> 1 is applied to the glass plate 1, the clip 4 swings around the guide bar 63 as a fulcrum and is attached to the lower end of the clip 4. 43 moves in the horizontal direction S <b> 1 along the horizontal groove 623 connected to the lower end of the guide groove 622. Similarly, as shown in FIG. 8B, when the force F <b> 2 is applied to the glass plate 1, the clip 4 swings around the guide bar 63 as a fulcrum, and the shaft body 43 extends along the horizontal groove 623. To move in the horizontal direction S2. Thereby, the force which the glass plate 1 received to the thickness direction can be released, and the force which acts on the glass plate 1 can be relieved.

  And in order to remove the glass plate 1 from the holder 3, the glass plate 1 should just be pulled up. Thereby, since the weight of the glass plate 1 acting on the clip 4 is removed, the clip 4 is urged upward by the spring 5. When most of the clip 4 is positioned above the guide bar 63, the second clamping member 42 swings away from the first clamping member 41 by the action of the center of gravity. As a result, the holding state of the glass plate 1 by both the holding members 41 and 42 is released, and the glass plate 1 can be detached from the clip 4.

<4 Features>
As described above, according to the present embodiment, the glass plate 1 can be clamped by the clip 4 by disposing the glass plate 1 between the first clamping member 41 and the second clamping member 42 of the clip 4. it can. Moreover, since the clip 4 is supported by the support body 6, if the glass plate 1 is attached to the clip 4, the glass plate 1 will be supported by the support body 6 in a perpendicular attitude. Therefore, unlike the conventional example, the glass plate 1 can be held by a simple operation. Further, since the clip 4 is biased upward by the spring 5, the impact when the glass plate 1 is disposed on the clip 4 can be reduced by the spring 5. Therefore, it is possible to prevent the glass plate 1 from being damaged by an impact when the glass plate 1 is placed.
