Description

  The present invention relates to a structure of a thumb turn seat (hereinafter simply referred to as a thumb turn seat), and more particularly to a thumb turn seat that facilitates installation work in the field.

  As shown in FIG. 1 of Patent Document 1 below, the conventional general thumb turn is attached by attaching a cylinder lock 6 to the door by a pair of mounting screws 12 and 12 penetrating the thumb turn seat 11, the door 9 and the lock box 1. Call it on the outer surface and fix the thumb turn seat on the inner surface of the door by the reaction force.

  Further, for the change in the right and left hand of the door, since the free side edge of the door 9 faces left in FIG. 1 of Patent Document 1, the lock box 3 is pulled out together with the front plate 3 and turned over, that is, the lock. The lock box 1 is inserted into the interior space of the door with the top and bottom of the box being the same, with the side plate of the lock box that has been facing the room facing the inside facing the outside.

  In this case, since the mounting screw hole in FIG. 1 of the above-mentioned patent document is on the horizontal line, the thumb turn seat can be attached to the door surface without changing the direction (the angular position around the rotation axis of the thumb turn).

In addition, the right-and-left side of the door means whether the hinge is on the left side or the right side when the door is viewed in the space where the door opens.

  Since the thickness of a normal lock box can be made sufficiently large, a clutch mechanism for connecting the thumb turn and the cylinder lock can be arranged along the rotation shaft of the thumb turn. It is easy to open the screw hole on the horizontal line and deal with the right and left side of the door.

  However, in the case of a thin lock box as shown in FIGS. 1 to 3, it is necessary to develop the clutch mechanism on a plane parallel to the side plate of the lock box.

  Incidentally, the latch lock shown in FIGS. 1 to 3 is attached to a door of a toilet or bathroom, for example, and is not shown, for example, fitted in a handle mounting hole of a retractor 2 provided in the upper part of the lock box 1. By rotating the handle shaft clockwise in FIG. 2, the latch bolt 5 is pulled from the front plate 6 through the idle lever 4 as shown in FIG.

  At this time, if the stopper 7 movable in the vertical direction in the lock box 1 is placed at the position shown in FIG. 2, the latch bolt 5 cannot be retracted, and the stopper 7 moves as shown in FIG. The latch bolt 5 can be retracted if it is placed at a position where it does not interfere with.

  The stopper 7 rotates the thumb turn 8 shown in FIG. 4 so that the operating arm 9 is converted into the clock face as shown in FIG. 2 and the angle position at 12 o'clock as shown in FIG. Then it goes up and down by placing it at an angular position of 3 degrees.

  The thumb turn 8 and the operating arm 9 are formed by inserting a thumb turn shaft 11 (see FIG. 5) having a square cross section through a thumb turn shaft hole 12 (see FIGS. 2 and 3) formed at the base end of the operating arm. In a state where the rotation is stopped via the thumb turn shaft 11, the two are integrally connected.

  Since the illustrated lock box is thin and has the above-described structure, the pair of mounting holes 13 and 13 through which the mounting screws in Patent Document 1 pass cannot be disposed on the horizontal line, and 45 degrees with respect to the horizontal line or the vertical line. It must be placed on an inclined line.

However, as described above, when the line connecting the mounting holes 13 and 13 is opened obliquely with respect to the horizontal line or the vertical line, the lock box is turned over according to the left and right side of the door, and the new one is installed. The angular positions of the mounting holes 13 and 13 and the angular position of the thumb turn 8 are shifted from the previous one by 90 degrees.
This can be easily found by looking over the light upside down in FIG.

  In this case, there is no problem when the projected shape of the thumb turn seat on the door surface is circular, but in the case of an irregular shape, for example, as shown in FIG. 4, the projected shape of the thumb turn seat on the door surface is square and the hairline is in a certain direction. In the case of entering, or not shown, for example, in the case of an ellipse, the design changes depending on the direction of the hairline or the horizontal ellipse becomes vertical although the square is not inclined.

  Also, especially when the thumb turn seat is square, the cap-shaped thumb turn seat cover can be inserted by changing the angular position, but if you do not know the structure, you can not come up with such a mounting method, installation work in the field Becomes difficult.

  Therefore, the present invention provides a thumb turn that can facilitate the mounting operation of the thumb turn seat even when the line connecting the thumb turn seat mounting holes is oblique and the projected shape of the thumb turn seat on the door surface is irregular. The purpose is that.

  In order to achieve the above object, the invention described in claim 1 is a circular thick plate having a thumb turn guide hole which is fitted to the thumb turn shaft in the center, and a pair of mounting rods at the outer peripheral portion of one surface. And a first board having a female screw hole formed at the tip of each mounting rod, and a thick plate with an irregular projection shape on the door surface, and an opening that loosely fits the thumb turn shaft at the center. A second substrate is formed by forming a bottomed first substrate guide hole that is rotatably fitted to the first substrate on the indoor side in the plate thickness direction, and the first substrate of the second substrate. A pair of arc-shaped angle restricting openings are formed symmetrically with respect to the central axis at the outer peripheral portion of the bottom surface of the guide hole, and the first board is inserted so that each mounting rod of the first substrate is inserted into the corresponding angle restricting opening. Fit into the first board guide hole, and attach the mounting rod to one end of the angle regulation opening. Each mounting rod is aligned with the corresponding mounting hole of the lock box, and when the mounting rod is brought into contact with the other end of the angle restriction opening, each mounting rod corresponds to the wrongness of the door. By aligning the lock box with the mounting hole of the lock box whose angular position is shifted by turning the lock box upside down, a third board is provided on the outer surface of the door, and the third board is attached to the lock box at at least one angular position. A pair of mounting screw holes that are aligned with the holes are opened, a mounting screw is inserted from the outer surface side of the mounting screw hole of the third substrate, and its tip is screwed into the female screw hole of the mounting rod of the first substrate. The first to third substrates are fixed to the inner and outer surfaces of the door so that the substrate is called on the inner surface of the door, and a thin box-like seat cover is fitted so as to cover the first and second substrates or the third substrate. It is characterized by that.

  When the thumb turn seat according to the present invention configured as described above is mounted on the door with the lock box turned upside down corresponding to the left and right sides of the door, the angular position of the mounting hole of the lock box is shifted by 90 degrees, for example. The desired effect is that the mounting screw and the mounting rod can be aligned with the lock box mounting hole at the new angular position by simply rotating the first board 90 degrees within the first board guiding hole of the second board and then fixing it. Play.

  Since the angular position of the outdoor mounting screw and the indoor mounting rod can be changed by 90 degrees, the line connecting the pair of mounting holes of the thumb turn seat crosses the horizontal line, and the thumb turn seat Even when the projected shape of the door on the door surface is irregular, the thumb turn seat can be easily attached.
