Description

[Detailed Description of the Invention] The present invention relates to a door head device for fittings in which the width of the door neck of the fittings can be adjusted by screw adjustment according to the width of the lintel groove.

In general, lintels have different groove widths depending on the region, and the groove width gradually widens as the inner wall of the lintel wears down over many years of use, so it is necessary to have a door head that fits the lintel groove. has been done. Therefore, in recent years, an adjustment block made of a polyhedron having a plurality of protruding surfaces with different protruding widths has been removably attached to the door neck of the fittings to adjust it to suit each groove width. The block cannot be attached or removed unless the fittings are removed from the lintel groove, and whether or not the adjustment has been made can only be determined after the fittings are reattached to the lintel groove, so if the adjustment is inappropriate. has the disadvantage that the above-mentioned operation must be performed again, and therefore the above-mentioned adjustment operation requires a great deal of effort.

The present invention has been made in view of the above points, and has a structure in which the width of the door neck can be adjusted by rotating a screw, so that the width can be adjusted while the fittings are attached to the lintel. To provide a door head device for fittings in which a more appropriate fitting of the door head to the groove can be obtained by performing stepless adjustment.

Embodiments of the present invention will be described below based on the drawings. Figure 1 is a perspective view of the fittings equipped with the door neck device of the present invention, Figure 2 is a perspective view of the door neck, Figure 3 is a cross-sectional view of the main part, and Figure 4 is the AA cross section of Figure 3. 5 is an exploded view of the main part of FIG. 3.

In each of the above figures, the door head device of the present embodiment includes an adjusting screw 2, a wedge body 3, and an adjusting body 4, each of which is provided in conjunction with a door neck body 1 in the upper part of a fitting.

The adjustment screw 2 is rotatably supported on the side wall 5 of the door neck main body 1 through a through hole 6, and a wedge body 3 is attached to the door neck main body so that it can move forward and backward. This adjustment screw 2 is attached to a retaining ring 7 inside the side wall 5.
By fitting it in, it is prevented from coming out of the through hole 6. Since the head of the adjustment screw 2 is located on the side surface of the door neck body 1, it can be rotated from the side with a screwdriver. Furthermore, since the head is housed in the recess 8 of the door neck body 1, it does not come into contact with the vertical frame when the shoji body 20 is opened or closed, and there is no inconvenience of it being exposed to the outside.

The wedge body 3 has a sliding surface 9a facing the adjusting body 4 in contact with a sliding surface 9b of the adjusting body 4, and is moved forward and backward by rotating the adjusting screw 2. The wedge body 3 has a substantially triangular shape when viewed from above, with its inclined surface serving as a sliding surface 9a, and has a screw hole 10 formed in the longitudinal direction of the center, into which the adjustment screw 2 is screwed. By this rotational operation of the adjustment screw 2, the wedge body 3 whose rotation is regulated by the adjustment body 4 etc. moves forward and backward in the longitudinal direction.

Note that the wedge body 3 may have a simple through hole instead of the screw hole 10, and the adjustment screw 2 can be inserted into the through hole.
Loosely fit it, and screw a nut onto its tip,
By restricting the rotation of the nut within the door neck main body, the wedge body 3 can be substantially moved forward and backward.

The adjusting body 4 has its sliding surface 9b pressed against the wedge body 3 through an elastic material 11, and as the wedge body 3 advances and retreats, a projecting piece 12 protrudes toward the inner wall side of the lintel groove 21. The width is adjusted according to the kamoi ditch width. This adjusting body 4 is located between the wedge body 3 and the retaining ring 7 of the adjusting screw 2 in the door neck main body, and the protruding piece 12 is fixed to the door neck main body 1 by two elastic members 11, 11. It is urged to be buried through the side passage hole 13, and its sliding surface 9b is pressed against the sliding surface 9a of the wedge body 3.

Incidentally, on both sides of the protruding piece 12 in the adjusting body 4, a receiving hole 1 is provided for an elastic material 11 made of a coil spring, for example.
4 is formed to facilitate positioning of the elastic member 11 and to prevent misalignment. As the elastic material 11, a plate spring or the like may be used in addition to a coil spring. Sliding surface 9 formed by an inclined surface
An escape hole 15 is formed in a part of b to avoid contact with the adjustment screw 2. Of course, if the wedge body 3 is provided between the adjustment body 4 and the retaining ring 7, the relief hole 15 becomes unnecessary.

The inside of the door neck main body 1 is the wedge body 3.
It is formed with a space in which the adjustment body 4 and the like can be housed, and after these are housed in conjunction with each other, a lid body 16 is attached to the upper surface thereof. This lid body 16 is the door neck body 1
It is formed to have the same width as the lintel groove 21 so as to fit within the lintel groove 21. The door neck main body 1 is configured such that its side portions fit into the adjustment levers 23 of the upper stile 22, and its lower surface portion fits into a vertical stile (not shown). The protruding piece 12 of the adjustment body 4 attached to the door neck body 1 may be made to protrude from the front side of the door neck body 1 as in the embodiment, or may be made to protrude from the back side of the door neck body 1.

Next, the assembly order of the above door neck device will be explained. First, the adjusting body 4 is housed inside the door neck body 1 with the elastic material 11 interposed therebetween, and the wedge body 3 is housed in the door neck body with its sliding surfaces 9a and 9b facing each other. Next, insert the adjustment screw 2 through the through hole 6 provided in the side wall 5 of the door neck body 1, screw the tip end into the screw hole 10 of the wedge body 3, and attach the lid body 16 to the top surface of the door neck body 1. do. Note that the retaining ring 7 of the adjustment screw 2 is used when inserting the adjustment screw 2 into the through hole 6.
Or install it later.

Since the door head device of the present invention is constructed as described above, by rotating the adjustment screw from the side of the fitting, the wedge body can be advanced or retreated, and the projecting piece of the adjustment body can freely protrude or move toward the inner wall side of the lintel. Since it can be moved backward, the width of the door neck can be freely adjusted while the fittings are attached to the lintel. Moreover, since the width adjustment is carried out in a stepless manner by rotating the screws, more appropriate width fine adjustment can be made and the opening and closing operations of the shoji can be made more smoothly. Furthermore, since the width adjustment is performed using a wedge method by rotating a screw, the structure is simplified and the possibility of failure is reduced to the utmost.
