Description

[Detailed Description of the Invention] This invention relates to a fitting height adjustment fitting for metal shoji fittings that allows the installation height to be easily adjusted.

To adjust the height of conventional metal shoji installations, the legs of the adjustment block are inserted and fixed into the vertical frame.
The arm of the block is inserted and locked into the adjustment bar that can be freely retracted from the side stile, and the height of the fittings can be adjusted by moving the block up and down.The outer box of the shaft height adjustment door wheel is inserted and fixed into the side stile. However, what was mainly used was that the inner box was attached to an adjustment bar that could be moved in and out of the horizontal stile, and the height of the fittings could be adjusted by moving the inner box up and down. However, the adjustment block must be installed across the stile and the adjustment sill, and the shaft height adjustment door wheel must also be installed straddling the stile and the adjustment sill, so installation of these items is cumbersome, and the adjustment sill is difficult to install. It was also difficult to remove the chisel.

Therefore, this idea was devised to create a height adjustment metal fitting that can be attached to either the horizontal stile or the adjustment beam to adjust the height.

Next, the structure of the adjustment fitting according to the present invention will be explained with reference to the drawings of the embodiment. The shaft support pieces 3, 3' are provided oppositely at the center of both sides of the rectangular base plate 2, and between the left and right shaft support pieces 3, 3',
A left leg 4 that can be raised and lowered on the left side of the shaft support pieces 3 and 3' and a right leg 5 that can be raised and lowered on the right side are symmetrically supported, and either one of the left leg tip 4a and the right leg tip 5a is supported. and the nut 6 on the other side.
A guide body 7 facing the guide body 6 is rotatably provided, and the guide body 6
The screw 8 reaches the nut 7 and screws into the nut 7.
The shafts 6a and 7a of the guide body 6 and nut 7 are supported from the shaft support pieces 3 and 3'. It protrudes to the outside, and a mounting hole 12 is appropriately bored in the board 2.

A in the figure is a horizontal stile that constitutes the shoji fittings, and the horizontal stile A has a connecting wall a3 between the inner and outer walls a1 and a2, and a vacant room H that opens toward the outer periphery from the connecting wall a3.
Inward protrusions a4 and a5 are provided on the inner and outer walls a1 and a2 on the outer peripheral side of the connecting wall a3, and between the connecting wall a3 and the protrusions a4 and a5, the guide body 7 of the adjustment fitting 1 and the shaft of the nut 6 are provided. Insert 7a and 6a. Reference numeral B designates an adjustment crosspiece that can be inserted into the vacant room H of the horizontal stile A and can be moved in and out.

Since the adjustment fitting of the present invention has the above-mentioned structure, in order to use it for shoji fittings, the left leg 4 and the right leg 5, which are pivoted to the base plate shaft support pieces 3 and 3' of the adjustment fitting 1, must be connected in advance to the The legs are completely opened by rotating a screw 8 screwed into the nut 6 of the right leg 5 from the guide body 7. First, the guide body 7 of the adjustment fitting 1 and the shaft parts 7a, 6a of the nut 6 are
After inserting the screw head 8a toward the vertical stile C between the connecting wall a3 of the horizontal stile A and the inward protrusions a4 and a5, and inserting the adjustment fitting 1 into the empty space H of the horizontal stile A, Next, insert the adjustment bar B into the vacant room H of the horizontal stile A from the outside,
Either fix the adjustment bar B to the board 2 by screwing the screw S into the board mounting hole 12 of the adjustment fitting 1 inserted before the adjustment bar B, or first turn the screw head 8a toward the vertical frame C. The base plate 2 of the adjustment fitting 1 is fixed with screws S to the upper part of the inner circumferential wall f of the adjustment bar B, and the guide body 7 of the adjustment fitting 1 attached to the adjustment bar B and the shaft portions 7a, 6a of the nuts 6 are connected to each other.
is inserted between the connecting wall a3 of the horizontal stile A and the inward protrusions a4 and a5, and the adjustment bar B is inserted into the vacant room H of the horizontal stile A via the adjustment fitting 1 of the present invention so that it can freely appear and retract. be. At that time, the screw 8 of the adjustment fitting 1 is attached to a location where it can be rotated with a tool from the outside of the vertical stile C.

If the adjusting fitting 1 of the present invention is attached to the shoji fittings using the above method, when the installation height of the fitting needs to be adjusted, the screw 8 of the adjusting fitting 1 attached to the fitting can be rotated with a tool. 8 is screwed into the nut 6 of the right leg 5 through the guide member 7 of the left leg 4, so as the screw 8 rotates, the left leg 4 and the right leg 5 can stand up and swing from the open state. can. When the left and right legs 4 and 5 are stood up and swung from the base plate 2, the guide body 7 provided on the left leg 4 and the shaft portions 7a and 6a of the nut 6 provided on the right leg 5 move toward the horizontal stile A.
Because it is inserted between the connecting wall a3 and the inward protrusions a4 and a5, respectively, and cannot move up and down, the adjustment bar B fixed to the base plate 2 is inserted into the vacant room H of the horizontal stile A so that it can appear and retract. , as the left and right legs 4 and 5 stand up and swing, the board 2 comes out of the connecting wall a3 of the horizontal stile A toward the outer periphery, and the adjustment bar B, which is fixed to the board 2 with screws S, moves toward the outer periphery from the vacant room H of the horizontal stile A. The installation height of the fittings is increased by the protrusion of the adjustment beam B. Furthermore, the left leg 4 and the right leg 5 of the adjustment fitting 1 once erected can be swung from the erect state to the direction of collapse by rotating the screw 8 in the opposite direction to the direction when erected. .

Note that the specific implementation of the invention is not limited to the above embodiment, and the left leg 4 is provided with a left-handed screw nut 6, the right leg 5 is provided with a right-handed screw nut 6', and between both nuts 6, 6'. Even if the left and right legs 4 and 5 are screwed in as shown in FIGS. 12 and 13, the left and right legs 4 and 5 can be raised and lowered symmetrically. Of course, the specific shape and structure of the base plate 2, left and right legs 4, 5, guide body 7, nuts 6, and screws 8, which constitute the adjustment fitting of the present invention, may be changed as appropriate unless it goes against the gist of this invention. It is possible.

Therefore, if the adjustment fittings of the present invention are used to adjust the installation height of shoji fittings, the adjustment fittings will allow the left leg and right leg, which are pivotally supported on the board, to be inserted into the nut of the right leg from the guide body of the left leg. The adjustment beam, which is fixed to the board according to the ups and downs of the left and right legs, rises and falls at the same time when rotated, and comes out and disappears from the empty space of the horizontal stile to adjust the installation height of the fittings. Not only can the height adjustment operation be performed accurately and in a stable state, but the adjustment operation is also very easy. Moreover, since the adjustment fitting of the present invention has a thickness of only about 1 cm when the left and right legs are completely laid down, the space required for installing the adjustment fitting can be significantly smaller than that of the conventional one, and installation on the shoji fittings is also very easy. In addition, the left and right legs of the adjustable fitting of this invention are stable in any standing state unless the screws are turned, so the left and right legs of the adjusting fitting will not fall down while the shoji fittings are being opened and closed. The adjustment fittings of the present invention have a significant practical effect in simplifying the adjustment of the installation height of shoji fittings, such as the ability to remove only the adjustment bars while leaving the adjustment fittings on the horizontal stile.
