Description

[Detailed description of the invention] In the present invention, when attaching a frame such as an entrance sash to an opening in a building frame, a waste frame is fixed in advance to the opening of the building frame, and the entrance sash etc. is attached to the waste frame. The present invention relates to a structure for attaching a frame, and particularly to a connection structure between a top frame and a vertical frame.

Conventionally, when attaching frames such as window and entrance sash frames (hereinafter referred to as sash frames) to openings in building frames, sufficient clearance is created between the opening and the sash frames in advance, and when the sash frames are fitted, It was common practice to insert a packing material such as plywood into the clearance to close the clearance and maintain the shape of the sash frame while constructing the entrance sash frame.

However, in this conventional construction method, it is necessary to prepare a packing material that can fit tightly into the clearance, and if distortion is found in the sash frame, the packing material must be replaced again. However, there were drawbacks such as the inability to ensure construction accuracy despite the labor involved in construction. In particular, these shortcomings are
This problem was most noticeable in doors with large openings, both in terms of area and weight, such as entrance doors, and sometimes caused problems in opening and closing the door.

Therefore, the present invention introduces a waste frame body separately from the sash frame body as a mounting structure with high precision and excellent workability without using adjustment materials such as the above-mentioned packing material, and first, the opening of the building frame is It has already been proposed that the installation can be completed by simply fixing the sash frame to the sash frame and fitting the sash frame into the sash frame. It concerns structural improvements.

The gist of the present invention having the above-mentioned features is to attach a vertical frame mounting guide having a substantially L-shaped cross section, which is formed by cutting and raising a part of a vertical piece and protruding an elastic locking piece, to the end of the upper frame. It is fixed so as to protrude downward from the vertical piece and the upper frame, and at the same time the elastic locking piece of the vertical frame installation guide fits into the notch groove formed on the upper edge of the vertical frame. The vertical piece installation guide is arranged so that the cutout groove of the vertical piece fits into the cut-and-raised cavity formed between the surface of the vertical piece and the back surface of the elastic locking piece in the vertical piece installation guide. The present invention relates to a structure for attaching a top frame and a vertical frame in an entrance sash, etc., characterized in that the vertical frame and the vertical frame are joined face-to-face.

The present invention will be explained below based on the illustrated embodiment. Reference numeral 1 is a channel-shaped vertical frame fixed to the building frame, and the upper edge of the web 10 of this vertical frame 1 has a notch extending in the longitudinal direction. A recessed groove 11 is provided. Reference numeral 2 denotes a channel-shaped top frame 2 which is attached to the lower surface of 〓3. Reference numerals 23 and 24 are locking protrusions that extend in the longitudinal direction and are protruded from the inner surfaces of the flanges 21 and 22, respectively. 4
is a vertical frame installation guide with a substantially L-shaped cross section that is screwed to the web 20 of the upper vertical frame 2 so that its vertical piece projects downward;
is composed of a horizontal piece 40 that is joined to the upper frame 2 and a vertical piece 41 that extends downward continuously from the horizontal piece 40. An elastic locking piece 42 cut into a shape is integrally provided. Therefore, this elastic locking piece 42
extends in an inclined direction with respect to the surface of the vertical piece 41, and a cut-and-raised cavity 43 is formed between the surface of the vertical piece 41 and the back surface of the elastic locking piece 42.

In the above configuration, first, the web 2 of the upper drop frame 2
0 horizontal pieces 4 of the vertical frame installation guides 4, 4 on both ends
0, and then the upper edges of the pair of left and right vertical frames 1 are fitted and joined to the vertical pieces 41 of the vertical frame mounting guides 4, 4. In this case, as shown in FIG. , the elastic locking piece 42 of the vertical frame installation guide 4 fits into the notch groove 11 of the vertical frame 1,
On the other hand, the notch groove of the vertical frame 1 bites into the notch cavity 43 of the vertical frame mounting guide 4, so that
The top frame 2 and the vertical frame 1 are easily fitted and connected via the vertical frame mounting guide 4. The vertical frame 1 connected to the upper frame 2 is fixed to the building frame via fixing devices (not shown) such as screws (see FIG. 3).

Note that the sash frame 5 is attached to the vertical drop frame 1 and the upper cut frame 2 connected as described above, but first the left and right locking protrusions 23 protruding into the fitting groove 25 of the upper cut frame 2 , 24, and the upper frame 50 of the sash frame 5 is fitted between the upper frame 50 and the upper frame 50, and both sides of the upper frame 50 are supported by the respective locking protrusions 23, 24. Next, when the lower frame 51 side of the sash frame 5 is swung in one direction using the upper frame 50 as a fulcrum,
The locking claws 51a of the lower frame 51 engage with the mounting holes 13 of the lower frame holder 12 provided at the lower edge of the vertical frame 1 due to their elastic action, thus completing the installation of the sash frame 5. It is something to do.

The present invention has the above-mentioned structure and operation, and includes a vertical frame installation guide with an approximately L-shaped cross section, which is formed by cutting and raising a part of the vertical piece and protruding an elastic locking piece, at the end of the upper frame. The vertical piece is fixed so as to protrude downward from the top frame, and the elastic locking piece of the vertical frame installation guide is fitted into the notch groove formed on the upper edge of the vertical frame. At the same time, install the vertical frame so that the cutout groove of the vertical frame fits into the cut-and-raised gap formed between the surface of the vertical piece and the back surface of the elastic locking piece in the vertical frame installation guide. Since the guide and the vertical frame are joined face-to-face, the vertical frame and the upper vertical frame can be connected accurately and reliably with extremely simple operations. As a result, it not only helps to improve workability by eliminating the need for complicated screw-tightening work, but also has various effects such as improving the design appearance of the doorway by reducing the number of screw-tightening points as much as possible. It is.
