Description

  In the present invention, each of the upper and lower sides of the rectangular glass panel is fitted in a sash fixed to the housing side and supported so as to be movable in the direction along the panel surface. The present invention relates to a glass panel support structure in which a reinforcing material is integrally bonded and fixed along each of them.

In the glass panel support structure, each of the upper and lower sides of the rectangular glass panel is fitted in a sash fixed to the housing side so as to be movable in the direction along the panel surface. When it acts, there is an advantage that it is easy to prevent breakage of the glass panel by allowing relative displacement along the panel surface of the upper and lower sides of the glass panel and the sash.
In addition, since the reinforcing material is integrally bonded and fixed along the left and right sides of the glass panel, the glass panel can be fitted without being fitted into the sash that is fixed to the housing side of the left and right sides of the glass panel. Therefore, there is an advantage that it is easy to secure a wide visual field in the left-right direction through the glass panel (see, for example, Patent Document 1).

JP-A-6-185266

However, in order to be able to effectively regulate the bending deformation of the glass panel at the left and right sides even when a large wind pressure acts, it is necessary to bond and fix a large reinforcing material having a large bending rigidity. In such a case, there is a drawback that the advantage of easily securing a wide field of view in the left-right direction through the glass panel is easily impaired.
In addition, a small reinforcing material with low bending rigidity is bonded and fixed to ensure a wide left-right field of view through the glass panel, while effectively controlling the deformation of the glass panel even under large wind pressure. In order to be able to do so, it is necessary to employ a glass panel that has a high bending rigidity and is difficult to bend.
The present invention has been made in view of the above circumstances, and it is easy to prevent damage to the glass panel when an external force is applied due to an earthquake or the like, and has an advantage of easily securing a wide field of view in the left-right direction through the glass panel. Even if a glass panel with low bending rigidity is employed without any particular loss, it is an object to be able to effectively regulate the bending deformation of the glass panel when wind pressure is applied.

  The first characteristic configuration of the present invention is that each of the upper and lower sides of the rectangular glass panel is fitted in a sash fixed to the housing side and supported so as to be movable in a direction along the panel surface. A glass panel support structure in which a reinforcing material is integrally bonded and fixed along each of the left and right sides of the glass, and the reinforcing material can be relatively moved in a direction along the panel surface of the glass panel to a fixing portion on the housing side Is provided with a support portion for supporting the above.

[Action and effect]
Since the support part that supports the reinforcing material so as to be relatively movable in the direction along the panel surface of the glass panel is provided on the fixing part on the housing side, when an external force is applied due to an earthquake or the like, the glass against the fixing part of the reinforcing material is provided. The relative movement in the direction along the panel surface of the panel allows the relative displacement along the panel surface of the upper and lower sides of the glass panel and the sash to be restricted, while restricting the bending deformation of the reinforcing material. The stress generated locally can be relieved.
Therefore, it is easy to prevent the glass panel from being damaged when an external force is applied due to an earthquake or the like, and the glass panel when the wind pressure is applied without particularly detracting from the advantage of easily securing a wide visual field in the horizontal direction through the glass panel. Can be more effectively regulated.

  The second characteristic configuration of the present invention resides in that the reinforcing material is bonded and fixed in series over substantially the entire length of the left and right side portions.

[Action and effect]
Since the reinforcing materials are bonded and fixed in series over the substantially entire length of the left and right side portions, a plurality of reinforcing materials adjacent in the longitudinal direction are bonded and fixed to the left and right side portions, and the respective reinforcing materials are fixed to the housing side. Compared with the case where a support part is provided to support the part, the bending deformation of the glass panel when the wind pressure is applied can be regulated over almost the entire length at the left and right side parts of the glass panel, while the support structure is simplified. Can be achieved.
