BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame joining member that serves as a framework for shoji, etc.
And a joining member for joining the vertical frame.

[0002]

2. Description of the Related Art As a conventional method for joining wooden frames,
Japanese Utility Model Laid-Open No. 60-11985 and Japanese Patent Laid-Open No. 10-8225.
There is a method described in Japanese Patent No. 1 publication.

According to the joining method described in Japanese Utility Model Laid-Open No. 60-11985, nuts are placed in a horizontal frame or a vertical frame and bolts are passed through the vertical frame or the vertical frame to fix the screws. There was a problem that could not be secured sufficiently.

In this respect, in the method disclosed in Japanese Patent Laid-Open No. 10-82251, the accuracy of the wooden frame is ensured by forming a tenon on one side of the joint surface of the vertical frame and the horizontal frame and a tenon on the other side. It has a structure that

[0005]

However, in this case, in addition to the member for fixing the vertical frame and the horizontal frame, a tenon for improving the accuracy of the frame is required, resulting in an increase in the number of parts.

[0006] In addition, these wooden frames are usually fitted with glass or a cover plate, and a lower horizontal frame is provided with a door roller, and the door roller is placed on a rail of an outer frame provided in the building and the wooden frame is installed. It allows opening and closing of.

At this time, a guide rail provided on the outer frame of the building fits into a groove provided in the upper horizontal frame to prevent the wooden frame from falling, but the guide rail has a width larger than that of the groove. The width of the entire wooden frame is narrow, and when it is opened or closed, there will be shaking (play).

This is because it is difficult in terms of accuracy to minimize the gap between the groove provided in the upper horizontal frame and the width of the guide rail over the entire width of the frame, and it is difficult to make contact with the guide rail made of iron. This is because there is a problem in that the groove portion of the upper horizontal frame, which is a lot of wood, is worn.

In order to prevent this runout, the upper surface of the vertical frame is aligned with the height of the upper horizontal frame, and a runout preventing groove slightly larger than the width of the guide rail is formed on the upper surface of the vertical frame. Although countermeasures have been taken, it has been an unavoidable problem that the number of processing steps for the vertical frame increases and that the runout preventing groove wears due to contact with the guide rail.

In view of the above points, the present invention provides a frame joining member that can manufacture a wooden frame with high accuracy and that does not wear the wooden frame due to the guide rails provided on the outer frame of the building. To aim.

[0011]

In order to achieve the above object, the frame joining member of the present invention is a joining member of a wooden upper and lower frame and a vertical frame, and is fitted into a fitting hole provided at an end of the upper and lower frame. The receiving member includes a supporting member and a fixing member that is screwed into the receiving member through a positioning hole provided at an end of the vertical frame. The receiving member has a rail groove on its upper surface and penetrates in parallel with the rail groove. The fixing member is characterized by comprising a cylindrical positioning guide and a screw thread.

The joining member of the frame can reduce the number of parts by providing the fixing member with the cylindrical positioning guide and the screw thread, and the receiving member has the rail groove on the upper surface, so that the building is constructed. It is possible to provide a wooden frame (frame) in which the wooden frame does not wear due to the guide rails provided on the outer frame.

In this case, the side surface of the rail groove of the receiving member may be a curved surface having a convex portion near the center.

As a result, the contact with the guide rail provided on the outer frame of the building comes into contact with the wire instead of the surface, and the opening / closing resistance is small, and smooth opening / closing can be performed.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a frame joining member of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view for explaining a procedure for assembling a vertical frame and a horizontal frame using a frame joint member according to the present invention.
The upper frame (upper frame in the example in the figure) is provided with an upper groove 11 for preventing the wooden frame 1 from collapsing by a guide rail provided on the outer frame of the building and a lower groove 12 for attaching glass or a closing plate on the upper and lower surfaces thereof. The fitting convex portion 13 for fitting into the fitting concave portion 14 is formed at the end portion, the fitting hole 6 for fitting the receiving member 4 therein is provided, and the positioning hole 7a extending from the end surface of the fitting convex portion 13 to the fitting hole 6 is formed. Perforated.

The vertical frame 3 has a fitting concave portion 14 formed on one side surface thereof to allow the fitting convex portion 13 of the upper and lower frame 2 to be fitted therein. Like the lower groove 12 of the upper and lower stiles 2, it plays a role of a groove for attaching glass or a closing plate. On the other side surface of the vertical frame 3, a packing insertion groove 15 is formed over the entire length, into which the packing 15 that absorbs the impact on the contact surface with the vertical outer frame of the building is inserted. Reference numeral 7b denotes a positioning hole that is drilled at a position corresponding to the positioning hole 7a provided in the upper and lower frame 2 (hereinafter simply referred to as "positioning hole 7").

The receiving member 4 to be fitted in the fitting hole 6 of the upper and lower frame 2 has a rail groove 8 on its upper surface, and a screw hole 9 is bored in parallel with the rail groove 8. The center of the screw hole 9 is selected at a position that substantially coincides with the center of the positioning hole 7a in a state of being fitted in the upper and lower frame 2.

The fixing member 5 has a thread 11 similar to a normal screw structure, and a positioning guide 10 concentric with the rotation center axis of the thread 11. The outer diameter of the positioning guide 10 is substantially the same as the inner diameter of the positioning hole 7 (difference in the degree of interference fit).

In the above structure, the fitting convex portion 13 of the upper and lower frames 2 into which the receiving member 4 is fitted is fitted into the fitting concave portion 14 of the vertical frame 3, and the positioning holes 7a and 7b are aligned with each other to fix the fixing member 5. The position of the upper and lower frames 2 and the vertical frame 3 is determined by the positioning guide 10, and the upper and lower frames 2 and 3 are fixed by screwing the screw threads 11 into the screw holes 9 formed in the receiving member 4.

At this time, since the screw hole 9 of the receiving member 4 and the rail groove 8 are provided in parallel, the rail groove 8 is attached to the outer frame of the building by the completion of the work of fixing the upper and lower frames 2 and the vertical frames 3. Since the guide rail 10 has a parallel relationship with the guide rail 10, and the side surface of the rail groove 8 is formed by a curved surface having a convex portion near the center, the guide rail 10 does not come into contact with the surface. Few.

Although the frame joining member of the present invention has been described above based on its embodiments, the present invention is not limited to the configurations described in the above embodiments, and may be appropriately performed without departing from the spirit thereof. The configuration can be changed.

[0023]

As described above, according to the present invention, since the fixing member is provided with the positioning guide for ensuring the accuracy of the wooden frame, the number of parts can be reduced and the product can be provided at low cost. Further, since the receiving member has the rail groove on the upper surface, the wooden frame is not worn by the guide rail provided on the outer frame of the building.

Furthermore, when the rail groove side surface of the receiving member has a curved surface with a convex portion in the vicinity of the center, the contact with the guide rail provided on the outer frame of the building is not a surface contact but a line contact, and the opening and closing resistance thereof. It is possible to open and close smoothly with less effect.
