Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fitting adjustment device of the type in which an adjusting foot attached to the lower end of a fitting lower stile is moved up and down by rotation of an adjusting screw.

As this type of device that allows easy installation adjustment,
A fitting adjustment device disclosed in Japanese Utility Model Publication No. 53-39411 is known. In this conventional device, the adjustment screw is inserted from the lower stile to the lower adjustment stile, so there is no problem if the fitting is a screen door like the one shown in the drawing of the same publication, but there is no problem with the fittings, but there are muntins on the inner peripheral surface of the stile. The above-mentioned device cannot be applied to fittings such as shoji screens and sliding doors in which shoji or core materials are provided, which causes the inconvenience.

Therefore, in the present invention, although the adjustment screw is inserted from the lower adjustment sill to the lower stile, that is, in the opposite direction to the conventional device,
The purpose of the present invention is to propose a fitting adjustment device that allows installation adjustments to be made as easily as conventional ones.

The present invention will be explained below with reference to the illustrated embodiments. As shown in Figs. The present invention also relates to a fitting adjustment device in which an adjusting lower stile 3 is attached to the lower end of the lower stile 1, and the lower stile 3 is moved up and down by an adjusting screw 4. 3 has corner block 5,
Further, adjustment pieces 6 are fitted into the lower stile 1, that is, in this example, they are fitted and locked, and an adjustment screw 4 is interposed between the block 5 and the piece 6.

The corner block 5 is composed of a main body 5a that fits into the vertical frame 2, and a projecting piece 5b that projects horizontally from the main body 5a. Locking protrusion 3 of lower deck 3
The protruding piece 5b is inserted between the block 5a and the horizontal wall 3b, and the block 5 is locked in the vertical direction. Note that there are protrusions 5c, 5c on both sides of the protruding piece 5b.
Since these protrusions 5c, 5c come into pressure contact with the inner surfaces of both side walls of the lower leg 3, horizontal movement of the block 5 is also restricted.

Further, a vertical through hole 5d is bored in the protruding piece 5b, while a screwdriver can be inserted into the horizontal wall 3b of the lower adjustment step 3 at a position corresponding to the vertical hole 5d during installation adjustment. A through hole 3c is bored.
The block body 5a that fits into the vertical frame 2 may have a different fitting depth to the vertical frame 2 because the corner block 5 itself moves up and down with the adjustment lever 3.

The adjustment piece 6 fits into the lower stile 1 below the lower stile web 1a and is locked in the vertical direction. That is, the upper part of the adjustment piece 6 is fitted between the lower stile web 1a and the locking protrusions 1b, 1b, and the piece 6 has bulges 6a, 6a formed on the sides of the upper part. , this bulge 6a is connected to the protrusions 1b, 1
b, and the adjustment piece 6 itself is prevented from moving up and down. Further, a vertical screw hole 6b into which the adjustment screw 4 is screwed is formed at a proper location on the adjustment piece 6.

As described above, the adjustment screw 4 is interposed between the corner block 5 and the adjustment piece 6, and the vicinity of the head 4a of the screw 4 is rotatably locked to the block protruding piece 5b. , the tip of the screw is screwed into the adjustment piece 6. To explain this in detail, the adjustment screw 4 is provided with a narrow neck portion 4b with which the retaining ring 7 attached thereto engages, and furthermore, the distance T between the inner surface of the screw head 4a and the narrow neck portion 4b is the same as that described above. The retaining ring 7 is formed to be larger than the vertical distance t in the vertical hole 5d, and the outer diameter M of the retaining ring 7 is larger than the inner diameter N of the vertical hole 5d. Therefore, the adjusting screw 4 interposed between the corner block 5 and the adjusting piece 6 is held on the protruding piece 5b by its head 4a and retaining ring 7 while passing through the vertical hole 5d.
In other words, the corner block 5 is rotatably locked at that position, the tip of the screw is screwed into the screw hole 6b of the adjustment piece 6, and the rotation of the adjustment screw 4 causes the corner block 5 to move vertically relative to the adjustment piece 6. Accompanying this, the adjusting lower leg 3 moves up and down. For this operation, the fitting of the present invention may be removed from the sill, for example, the tip of a screwdriver may be inserted through the through hole 3c of the lower adjustment step 3, and the adjustment screw 4 may be rotated as appropriate.

As explained above, in the fitting adjustment device according to the present invention, the protruding piece of the corner block is fitted to the lower adjustment stile, and the adjustment piece is fitted to the lower stile, and the adjustment is made between these pieces. Since it is constructed with intervening screws, it is not only possible to adjust the installation of the fittings extremely easily just by rotating the adjustment screw, but it is also economical as there is no need for expensive metal devices such as adjustment fittings. In addition, since it has a structure that allows adjustment from below, it has the advantage that it can be applied to general fittings such as shoji and sliding doors, in which mumiko sashimi and core materials are arranged on the inner peripheral surface of the frame material, and The adjustment piece is slid and fitted between the web of the lower stile and the locking ridge, and the corner block is also slid and fitted between the horizontal wall of the lower adjustment stile and the locking ridge. As a result, the assembly work is considerably facilitated, and in addition, the protruding piece of the corner block has the advantage that it is firmly held by the retaining ring.
