Description

[Detailed Description of the Invention] The present invention relates to a sliding door corner block equipped with a groove width adjustment piece.

Fusuma corner tabs are attached to the corners of fusuma, and in recent years, some have been devised that allow the width of the fusuma to be adjusted relative to the lintel groove.

By the way, the above-mentioned block has a horizontal piece that fits into the upper frame of the sliding door or an adjustment step, and a vertical piece that fits into the vertical frame of the sliding door,
Furthermore, in the case of a fusuma corner block in which a pair of grooves are provided at the bottom of the horizontal piece to engage with the opposing protrusions at the upper end of the sash,
When attaching the groove width adjustment piece to the horizontal piece, an undesirable situation has arisen in that the protrusion of the above-mentioned beam becomes an obstacle.

Therefore, the present invention aims to eliminate the above-mentioned drawbacks by improving the above-mentioned type of sliding door corner block.

The present invention will be explained below with reference to the drawings. Figure 1 shows
An exploded perspective view of a corner part of a fusuma using a fusuma corner block according to the present invention, FIGS. 2 to 4 are views showing the corner part of the same, and FIGS. 5 to 7 are a fusuma corner block of the present invention. In this figure, the present invention is equipped with a horizontal piece 1 and a vertical piece 2, and at the bottom of the horizontal piece 1, there is a protrusion facing the upper end of the upper crosspiece 3 or the adjustment rod 4 (in this example, It is a fusuma corner block provided with a pair of grooves 6, 6 that engage with opposing protrusions 5, 5) of an adjustment rod 4, and furthermore, one side 7 of several pieces 1 is provided at an appropriate position on the horizontal piece 1. A concave groove 8 is provided which is open to the groove 6 and communicates with the groove 6, and a groove width adjustment piece 11 is provided in the groove 8.
8 to 10, the adjusting piece 11 has a loose fitting groove 12 for the protrusion 5 of the adjusting rod 4. It is constructed by providing an elongated screw hole 13 whose protruding width T from the horizontal piece 1 is variable.

Note that 17 is a vertical frame. As described above, the protrusion 5 of the adjustment rod 4 is fitted into and engaged with the groove 6.
The groove width a is set to be wider than the inside of the protrusion 5.

In addition, since the main block is attached to the corner of the sliding door, and therefore the horizontal piece 1 is located in the groove of the lintel (not shown), the groove width adjustment piece 11 that fits into the several pieces 1 is horizontal. It is undesirable for it to protrude upwardly from the upper surface 10 of the piece.

Therefore, in order to fit the piece 11 into the horizontal piece 1, the groove 8 is bored until it communicates with the groove 6.

Then, the adjustment piece 11 is fitted into this concave groove 8 and the protrusion width T from the horizontal piece 1 is made variable.
1 is provided with a loose fitting groove portion 12.

Therefore, the width t and the vertical width of the groove portion 12 have the following values.

That is, t1 = b + α (however, α = maximum value of T) t2≧C (however, C is the distance between the bottom of the groove 8 and the bottom of the groove 6) and corresponds to the value of the protrusion width T mentioned above. At least adjustment piece 1
The long diameter of the long hole 13 of 1 is determined.

Furthermore, a holding protrusion 14 that separately fits into the adjustment lever 4 is provided inside the joint between the two pieces 1 and 2 of the block.

Further, as shown in FIGS. 11 and 12, this block is used in a so-called height-adjustable sliding sliding door that can move up and down together with the adjustment lever 4, and the holding protrusion 14 has a , grooves 16.16 are provided which engage the internal protrusions 15, 15 of the adjustment bar 4.

In addition, in this example, as described above, the case where the horizontal piece 1 is inserted into the adjustment rod 4 has been explained, but the main block can also be implemented when the horizontal piece 1 is inserted into the upper crosspiece 3. Of course you can.

As explained above, the fusuma corner flock according to the present invention uses a groove width adjustment piece with a loose fitting groove and a long hole for screws, and also uses a groove width adjustment piece provided at an appropriate position on the horizontal piece. It is open on one side and fitted into a groove that communicates with the groove at the bottom of the horizontal piece, and therefore,
The loose fitting groove of the adjustment piece is fitted into the upper end opposing protrusion of the rod, which makes it possible to avoid the conventional situation where the protrusion becomes an obstacle to attaching the adjustment piece.1. In addition, since this is formed into a loose fitting groove, the adjustment piece can protrude from the horizontal piece within the range of the elongated hole provided in this, and this allows you to adjust the width of the Kanto and Kansai type lintel grooves. It is possible to erect a sliding door using the proposed blocks in either case.
