BACKGROUND OF THE INVENTION This invention relates to a connecting structure between a lower frame with a rail for a sliding door and a vertical frame, and more particularly, to a lower frame with a rail for a sliding door capable of removing dust and water on the lower frame. The present invention relates to a structure of a connection portion with a vertical frame.

[0002]

2. Description of the Related Art Conventionally, as a structure of a connecting portion between a vertical frame and a lower frame with a sliding door rail capable of removing dust and water as described above, for example, there is a structure shown in FIG.

A lower frame 101 with a rail for a sliding door shown in FIG.
Sliding door rails 101a and screen door rails 101c on the outer side (upper side in the figure) are provided with cuts 101d and 101e formed by retreating in the longitudinal direction, respectively, and a pair of standing walls 101f formed along the longitudinal direction. , 101f
, And is connected to a vertical frame (not shown) via the connecting body 102.

The connecting body 102 is fitted between the standing walls 101f, 101f of the lower frame 101 with a sliding door rail.
Cap portions 102a and 102c which are located in 1d and 101e to cover the respective ends of the sliding door rail 101a and the screen door rail 101c, a flat portion 102d which covers the cuts 101d and 101e from below, and a pair of standing walls 101f. ,
A pair of standing pieces 102f, 10 abut respectively on 101f.
2f and lower frame fixing pieces 1 that respectively contact the inward edges 101g, 101g of the pair of standing walls 101f, 101f.
02g, (102g) and the lower frame 101 of the flat portion 102d
The vertical frame fixing pieces 102h and 102i extend to the opposite side and are bent downward.

[0005] When connecting the lower frame 101 with a sliding door rail and the vertical frame, first, the connecting body 102 is fitted between the upright walls 101f, 101f, and the upright walls 101f, 10f.
The screw 10 which has passed through the screw insertion holes 101i, 101i provided in the respective inward edges 101g, 101g of 1f.
The screws 3 and 103 are screwed into screw holes 102j and (102j) provided in the lower frame fixing pieces 102g and 102g, respectively, and assembled to the lower frame 101 with rails for sliding doors. Next, the lower frame 101 with the sliding door rail is connected to the vertical frame (not shown) by screwing a tapping screw (not shown) from the side of the vertical frame (not shown) into the screw lower hole 102k provided in the vertical frame fixing piece 102h and fixing the screw. At this time, the end of the sliding door rail 101b on the inner side (lower side in the drawing) and the vertical frame on the flat portion 102d that covers the cuts 101d and 101e of the lower frame 101 with the sliding door rail from below. , Dust and water accumulated in the lower frame with sliding door rail 101 can be removed.

[0006]

However, in the above-mentioned conventional connection structure between the lower frame with the sliding door rail and the vertical frame, a step of cutting the lower frame material into a predetermined length and press working are performed. Since the lower frame 101 with a rail for a sliding door manufactured through the process of forming the cuts 101d and 101e is used, for example, when the lower frame 101 with a rail for a sliding door is shorter than the standard, There was a problem that it was not possible to take agile measures such as performing dimension adjustment at the connection work site between the lower frame 101 with the sliding door rail and the vertical frame.

When assembling the connecting body 102 to the lower frame 101 with a sliding door rail, the lower frame 1 with a sliding door rail is used.
01 inward edges 101 of the upright walls 101f, 101f
g, 101g, the screws 103, 103 penetrating the screw insertion holes 101i, 101i, respectively, are screwed into the screw holes 102j of the lower frame fixing piece 102g, so that it is easy to say that the assembling workability is excellent. In addition to the difficulty, the connecting body 102 itself is formed of stainless steel for rust prevention reasons. Therefore, when connecting the lower frame 101 with the sliding door rail to the vertical frame at the site,
Since the work of screwing the tapping screw into the screw lower hole 102k when fixing 02 to the vertical frame requires a considerable force, there is a problem that the workability of assembling the frame is not excellent. Resolving these problems has been a conventional problem.

[0008]

The purpose of the present invention is to focus on the above-mentioned conventional problems. For example, even if the lower frame with a sliding door rail is shorter than the standard, the lower frame with a sliding door rail can be used. In addition to being able to respond promptly at the connection work site with the vertical frame, the workability of assembling the lower frame with the sliding door rail to the connecting body that connects the lower frame with the sliding door rail and the vertical frame to the vertical frame is improved. It is an object of the present invention to provide a connecting portion structure between a lower frame with a sliding door rail and a vertical frame, which can also improve the workability of assembling the lower frame with a sliding door rail and a vertical frame. .

[0009]

According to the present invention, a connecting structure between a lower frame with a sliding door rail and a vertical frame according to the invention includes a connecting portion between the lower frame with a sliding door rail having a sliding door rail and the vertical frame. Between the end of the lower frame with the sliding door rail and the vertical frame,
A block having a main body that is substantially the same as or lower than the upper surface of the lower frame with a sliding door rail and an insertion portion inserted into an end of the lower frame with a sliding door rail is provided, and a main body of the block is provided. A vertical frame fixing portion that is covered with the vertical frame and is fixed to the vertical frame, and is inserted together with an insertion portion of the block into an end of the lower frame with the sliding door rail and fixed to a fixing portion provided at the end. It is characterized in that it has a configuration in which a connecting body having a lower frame fixing portion is provided, and the configuration of the connecting portion structure between the lower frame with the sliding door rail and the vertical frame solves the above-mentioned conventional problems. As a means for
In one embodiment, the block provided between the end of the lower frame with the sliding door rail and the vertical frame is a resin block.

[0010]

In the structure of the connecting portion between the lower frame with the sliding door rail and the vertical frame according to the present invention, the end of the lower frame with the sliding door rail is cut at a right angle so that it can be connected to the vertical frame. Therefore, for example, when the lower frame with the sliding door rail is shorter than the standard, at the connection work site between the lower frame with the sliding door rail and the vertical frame, the dimensions are adjusted only by cutting off the ends at right angles. It will be.

When the lower frame fixing portion of the connecting body is inserted into the end of the lower frame with the sliding door rail together with the insertion portion of the block, the lower frame fixing portion is provided at the end of the lower frame with the sliding door rail. Since the fixed body is fixed to the fixed portion, the connected body is assembled to the end of the lower frame with the sliding door rail, and the workability of assembling the connected body is improved.

Further, since the vertical frame fixing portion of the connecting body is covered with the main body of the block, the connecting body does not necessarily need to be formed of stainless steel, and the connecting body is made of, for example, cold-rolled steel. When it is formed, when the vertical frame is fixed to the vertical frame fixing portion using a tapping screw, the screwing work becomes very easy, and therefore, the assembling work of the lower frame with the sliding door rail and the vertical frame is also easy. Will be improved.
