DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical frame cap for closing an end face of a vertical frame when the horizontal frame is joined to a side surface of the vertical frame.

[0002]

2. Description of the Related Art In a joint portion of a sash frame assembled from a vertical frame and a horizontal frame, when the horizontal frame is joined to the side surface of the vertical frame and joined, the end face of the vertical frame is formed. To open it, a cap for closing its end face is inserted into the hollow part of the vertical frame.

[0003] Since the conventional cap has only a role of closing the end face of the vertical frame, the horizontal frame is determined based on the abutting state of the end face against the side surface of the vertical frame and the matching state of the screw holes of the horizontal frame and the vertical frame. Since the horizontal frame is joined to the vertical frame, there is no stability of the horizontal frame during positioning or joining, and if the positioning is not performed accurately, the horizontal frame may be twisted and joined to the vertical frame.

The cap of the vertical frame is placed inside the vertical frame.
Simply press-fit as in No. 100667, or screwed into the vertical frame as in Japanese Utility Model Publication No. 62-43104, or inserted into the vertical frame by engaging the projection inside the vertical frame, etc. Although the state is maintained, the press-fitting alone lacks the certainty of retaining, and the means such as screwing or engaging the vertical frame increases the number of processes on the vertical frame.

In view of the above background, the present invention proposes a cap that stabilizes a horizontal frame at the time of joining to a vertical frame, and ensures that the cap does not come off without processing the vertical frame.

[0006]

According to the first aspect of the present invention, a guide piece is protruded from a side surface of the end plate abutting against an end face of the vertical frame on the side of the horizontal frame, so that the guide piece is joined to the vertical frame at the time of joining to the vertical frame. Used for holding and positioning, ensuring the stability of the horizontal frame, increasing the accuracy of joining to the vertical frame, and preventing the cap from coming off after the sash frame is assembled.

The cap is inserted into the vertical frame before the horizontal frame is joined to the vertical frame, and when the horizontal frame is abutted against the side surface of the vertical frame, the guide piece is placed on the surface on the front side of the end plate. The horizontal frame is supported or held by the guide pieces by being in contact with the inner peripheral surface of the frame, and at the same time is positioned with respect to the vertical frame.

Since the horizontal frame is easily positioned with respect to the vertical frame, the workability of joining the horizontal frame and the vertical frame is improved, and the joining accuracy is increased. . In addition, since the joining accuracy is increased, light leakage from the butted surfaces is reliably prevented, and the airtightness and watertightness of the butted surfaces can be easily ensured by the interposition of the sealing material.

In the state where the horizontal frame is joined to the vertical frame, the guide piece engages with the prospective piece of the horizontal frame in the direction in which the cap comes out, so that it does not depend on means such as screwing or engaging the vertical frame. The cap is prevented from coming off.

Since the guide piece prevents the vertical frame from slipping out of the vertical frame, it is not necessary to process the inside of the vertical frame, and the manufacturing of the vertical frame is simplified as compared with the case of using means such as screws or engagement. The operation of attaching the cap is simplified.

Further, the thickness of the guide piece is made smaller than the thickness of the end plate, and a step is formed between the guide plate and the end plate so that the surface of the prospective piece of the horizontal frame and the surface of the end plate are flush with each other. Improve the appearance of the joint.

In this case, when the horizontal frame is abutted against the side surface of the vertical frame, the end face of the prospective piece of the horizontal frame that comes into contact with the guide piece abuts against the side surface of the end plate. Becomes more certain.

According to a second aspect of the present invention, the cap is formed integrally with the end plate, and a guide portion is formed on the outer periphery of the insertion portion inserted into the hollow portion of the vertical frame so as to be in close contact with the inner peripheral surface of the hollow portion of the vertical frame. Make sure to stop.

The insertion portion of the cap is in close contact with the inner peripheral surface of the vertical frame during insertion or press-fitting into the vertical frame, and the insertion state is maintained by frictional force. However, a guide portion is formed on the outer periphery of the insertion portion. Therefore, the contact pressure between the inner surface of the vertical frame and the inner peripheral surface of the vertical frame during press-fitting into the vertical frame increases, and the insertion state can be more reliably maintained than when only the insertion portion is used.
