  In a conventional sash frame, there is a case where, for example, a bead or a back-up material is used as an elastic body that supports glass by finishing at the construction site. In general, separate holding portions are used for the beads and the backup material. However, when separate elastic bodies are used, the construction becomes corresponding to each, and the construction cost increases. Therefore, the protrusion-shaped holding portion corresponding to the bead is replaced with a backup material.

  However, in the conventional sash frame, when the holding portion having a protruding shape corresponding to the bead is replaced with the backup material, the holding portion is held by engaging the holding portion with the end surface of the backup material. However, since the engaging convex portion protrudes toward the back-up material side at the tip of the protruding holding portion, the holding state becomes unstable due to partial contact.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a sash frame that can support a panel body without reducing the supporting force of the panel body.

  In order to achieve the above object, a sash frame according to the present invention is a sash frame in which a panel body is housed with respect to a frame body framed on four sides, and holds an elastic body that supports the peripheral portion of the panel body. It has a holding part, and the holding part is characterized in that the entire inside of the panel body in the in-panel direction is a smooth surface, and at least a convex part is formed on the outside.

  According to the sash frame of the present invention, when the elastic body is a bead, the bead can be held by fitting the holding portion into the fitting recess of the bead. Further, when the elastic body is a backup material, the elastic body can be held in a stable holding state while being in contact with the end face of the backup material over the entire smooth surface of the holding portion. In addition, it is not necessary to reduce the thickness of the backup material by forming a smooth surface on the holding portion, and it is possible to prevent a reduction in the supporting force that holds down the panel body by the backup material, and the depth of the sealing material provided in contact with the elastic body. Further, it can be provided without lowering.

  Further, when the elastic body is a bead, since one side of the holding portion is a smooth surface, the bead can be easily fitted to the holding portion by sliding or pushing, so that the mounting operation is facilitated.

  Moreover, the sash frame which concerns on this invention is good also as a structure by which the said holding | maintenance part is provided in each of 4 sides which comprise the said frame.

  In this case, since the holding portion can be applied to the four vertical and horizontal sides constituting the frame body, the panel body can be reliably supported by each side.

  According to the sash frame of the present invention, the panel body can be supported without reducing the supporting force of the panel body.
