Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for attaching a glass plate to a door. is provided around the front inner peripheral surface of the rectangular opening 3, and a stepped portion 6 for attaching the presser frame 5 is provided around the front inner circumferential surface of the rectangular opening 3, and is locked at the front center of both left and right edges and both upper and lower edges of the stepped portion 6. A protrusion 7 is formed, and the frame-shaped presser frame 5 is housed in the stepped portion 6 to sandwich the glass plate 2 between the presser frame 5 and the glass plate support frame 4, and the front surface of the presser frame 5 is locked by the protrusion 7. Attaching a glass plate to a door, each frame member 5a of the presser frame 5 is formed to be elastically deformable inwardly, and the outer circumferential surface of the presser frame 5 is formed into a tapered surface 12 that slopes inward toward the rear. It is related to the structure.

Conventionally, when attaching a glass plate to a door opening using a presser frame, fixing devices such as wood screws or nails were used to secure the presser frame to the door, so the heads of the wood screws or nails were exposed. There was a problem that the number of man-hours required for tightening the screws increased.

The present invention has been made in view of the above-mentioned points, and its object is to be able to attach a presser frame without using a fixing tool and to improve the appearance, and to improve the appearance of the presser frame. The objective is to provide a structure for easily attaching the glass plate to the door.

Hereinafter, the present invention will be explained in detail based on illustrated embodiments.

The door 1 is made of wood, for example, and has a vertical stile 8 and a horizontal stile 9.
A glass plate 2 is attached to a rectangular opening 3 formed in the middle frame 10. Rectangular opening 3
A glass plate support frame 4 is integrally provided around the rear inner peripheral surface of the frame. A stepped portion 6 is provided around the front inner peripheral surface of the rectangular opening 3 . A linear locking protrusion 7 is formed at the center of the front side of both left and right edges and both upper and lower edges of the stepped portion 6. Reference numeral 5 denotes a holding frame made of wood or synthetic resin, and each frame member 5a is elastically deformable inward. Since the presser frame 5 is formed into a frame shape, each frame material 5a forming the frame-shaped presser frame 5 has both ends as fulcrums, and the center portion is inward, regardless of whether it is made of synthetic resin or wood. The material can be sufficiently elastically deformed to flex. The outer peripheral surface of each frame member 5a is inclined inward toward the rear to form a tapered surface 12. In the holding frame 5, the stepped portions 6 are fitted, and the glass plate 2 is held between the holding frame 5 and the glass plate supporting frame 4. 11 is a bead.

FIG. 4 shows the operation of attaching the glass plate 2. First, the glass plate 2 is fitted into the rectangular opening 3, and then an external force is applied to the holding frame 5 to bend each frame member 5a inward. Next, the presser frame 5 is pushed into the stepped portion 6. At this time, the tapered surface 12 of the presser frame 5 is slid on the inner edge of the locking protrusion 7, and the presser frame 5 is pushed into and fitted into the stepped portion 6 using the tapered surface 12 as a guide.
Thereafter, the external force is released and the outer peripheral edge of the front surface of the presser frame 5 is locked to the locking protrusion 7.

FIG. 5 shows another embodiment of the invention. A protrusion 13 is provided on the front surface of the presser frame 5 from slightly inward to the front than the tapered surface 12 on the outer periphery, and this protrusion 13 is formed over the entire circumference of the presser frame 5. When the presser frame 5 is fitted into the stepped portion 6, a groove 14 is formed by the locking protrusion 7 and the protrusion 13.

As described above, the present invention provides a glass plate support frame around the rear inner circumferential surface of a rectangular opening for attaching a glass plate of a door, and a stepped strip for attaching a presser frame to the front inner circumferential surface of the rectangular opening. A locking protrusion is formed at the front center of both left and right edges and both upper and lower edges of the stepped portion, and a frame-shaped presser frame is housed in the stepped portion to hold the glass plate and hold the frame and the glass plate together. In addition to being clamped with the supporting picture frame, the front side of the presser frame is locked to the locking protrusion, and each frame material of the presser frame is formed to be elastically deformable inward, so that the presser frame can be used as a rectangular opening for attaching a glass plate. When fitting into the stepped section of the frame, by bending each frame material of the presser frame inward, each frame material can be fitted into the stepped section beyond the locking protrusion on the front edge of the stepped section. After that, by restoring the presser frame, each frame member is locked at the locking protrusion and will not come off the stepped part.As a result, the presser frame can be attached to the door without using a fixing device. Moreover, since the outer circumferential surface of the presser frame is made into a tapered surface that slopes inward toward the rear, when bending the presser frame to fit it into the stepped section, the tapered surface is slid onto the locking protrusion while the step is inserted. The tapered surface of the presser frame serves as a guide, which simplifies the attachment operation of the presser frame.
