Abstract

PURPOSE:To make improvements in mounting strength between a framework and an end plate by forming a bottom spread-form glue reservoir in an intermediate part of mutual joining surfaces of an architrave member, and filling up a bonding agent in this reservoir. CONSTITUTION:An architrave member 15 is stuck to a frame work 12 by a bonding agent 17 applied to a framework mounting surface 15B, and further a pin cutter 19 is driven in and clamped tight. In addition, the bonding agent 17 is applied to or filled up in mutual joining surfaces 15A and glue reservoirs 15C, then the end plate 14 is mounted on each end plate fitting step parts 15D. In succession, from the other side mutual joining surface 15A to the framework mounting surface 15B, the bonding agent 17 is further applied to or filled up in the glue reservoir C, attaching it to the framework 12, and also the architrave member 15B on one side is joined, thereby constituting an architrave material 13. In a state that the end plate 14 is fitted in the end plate fitting step parts 15D, 15D of both these architrave members 15 and 15, the architrave member 15 on the other is clamped tight by the pin cutter 18.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint structure of a frame and a mirror plate applied to a door or the like.

[0002]

2. Description of the Related Art As shown in FIG. 5, a door (1) has a frame (2).
There is a structure in which the end plate (4) is attached to the inside of the frame through the frame material (3). Conventionally, as shown in FIG. 6, a frame member (3) is composed of a pair of left and right frame members (5, 5), and each of the frame members (5, 5) has a substantially L-shaped cross section, and one frame member is (5) is fixed to the peripheral edge of the end plate (4) by a pin tacker (6) on its side surface (5A), and as shown in FIG. 7, both frame members (5, 5) are adhesively attached on the back surface. (7,7) adheres to the frame (2), and further the pin tucker (8,8) fixes both frame members (5,5) to the frame (2) from the front side and both frame members are fixed. (5,5) sandwiched the end plate (4) and constituted the frame material (3).

[0003]

However, in the above conventional structure, the frame members (5, 5) are not adhered to each other, and
The joint strength to (2) is not sufficient, and one frame member (5) is fixed to the peripheral edge of the end plate (4) with a pin tacker (6) and then fixed to the frame (2) during assembly. The process was complicated to attach.

[0004]

As a means for solving the above-mentioned conventional problems, the present invention provides a pair of left and right frame members (15,
15) is a structure in which the end plate (14) is joined to the frame (12) through a frame material (13) consisting of the frame member (13), and the mutual joint surfaces (15A, 15A) that are the side surfaces of the frame member (15, 15). A glue spread (15C, 15C) in the shape of a bottom spreading groove is formed in the middle part, and the mutual joint surface (15A, 15A)
End plate fitting steps (15D, 15D) are formed on the front side of the frame member (15A, 15A) and the frame mounting surface (15B, 15B) which is the back surface. The adhesive agent (17) is applied and the glue reservoir (15C, 15C) is also filled with the adhesive agent (17), and a pair of left and right frame members (15, 15) are provided by the adhesive agent (17).
Are joined via mutual joint surfaces (15A, 15A) and the frame mounting surface
(15B, 15B) is bonded to the frame (12) via the frame member.
(15,15) End plate (14) is fitted into end plate fitting groove (15E) formed by mutual end plate fitting steps (15D, 15D) and adhesive (17)
It provides a joint structure between the frame (12) fixed by (4) and the end plate (14).

[0005]

In the present invention, the frame member (15, 15) is framed with the adhesive (17).
The frame members (15, 15) are also adhered to each other by the adhesive (17) while being adhered to the (12). And the adhesive
(17) is also filled in the bottom spread groove-shaped glue reservoir (15C, 15C) of the mutual joint surface (15A, 15A) of the frame member (15, 15), so the glue reservoir (15C, 15C) The mutual bonding strength becomes extremely high due to the anchoring effect of the adhesive portion filled in. The pair of left and right frame members (15,
The frame member (13) is constituted by 15), and the mirror plate (14) is fitted in the mirror plate fitting groove (15E) formed by the mirror plate fitting stepped portions (15D, 15D) of the pair of frame members (15, 15). The peripheral edge portion of is fitted and fixed with an adhesive (17).

[0006]

EXAMPLE As shown in FIG. 5, the door (11) has a frame (12) and a frame (1).
The end plate (1) attached to the inside of (2) via the frame material (13)
4) consists of and. As shown in FIG. 1, the frame member (13) is composed of a pair of left and right frame members (15, 15), and is made of wood or plastic such as polyvinyl chloride or acrylonitrile-butadiene-styrene resin. The frame member (15, 15) has a substantially L-shaped cross section, and a bottom spreading groove-shaped glue reservoir (15C, 15C) is formed in the middle part of the mutual joint surface (15A, 15A) which is a side surface. Further, end plate fitting step portions (15D, 15D) are formed on the mutual joint surfaces (15A, 15A) from the front side. Also the frame (12)
Consists of a column (12A) and front plates (12B, 12B) joined to the front and back of the column (12A).

An adhesive (17) is applied to the frame mounting surface (15B) which is one of the back surfaces of the frame member (15), and the frame member (15) is shown in FIG. 2 by the adhesive (17). As described above, it is adhered to the frame (12), and then the pin tucker (18) is driven and fixed from the surface side. An adhesive agent (17) is further applied to the mutual joint surface (15A) of the frame member (15), and at the same time, the glue pool of the mutual joint surface (15A) is accumulated.
The adhesive (17) is also filled in (15C), and the end plate (14) is placed on the end plate fitting step (15D) as shown in FIG. In this state, from the other mutual joint surface (15A) of the frame member (15) to the frame mounting surface (15A).
Apply adhesive (17) over B), then fill the glue reservoir (15C) with adhesive (17) and attach to the frame (12) as shown in Fig. 4 and join one frame member (15). To form a frame material (13), and the end plate (14) is used for both frame members (15, 15).
Then, the other frame member (15) is fixed by the pin tacker (18). As described above, the frame members (15, 15) are bonded to each other with a sufficient strength.
The bottom of the mutual joint surface (15A, 15A) of (15, 15) spreads very much due to the anchor effect of the adhesive (17) filled in the groove-shaped glue reservoir (15C, 15C).

[0008]

Therefore, in the present invention, the attachment strength of the frame member in the structure in which the end plates are joined to each other via the frame member is significantly improved, and one frame member and the peripheral portion of the end plate are pinned during assembly. The step of fastening with a tucker can be omitted.
