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 multiple 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, but this block method is The block cannot be attached or removed unless the fittings have been removed from the lintel groove, and whether or not the fittings have been properly adjusted can only be determined after the fittings are reattached to the lintel groove. In this case, the above-mentioned operation must be performed again, which has the drawback that 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 neck 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 a fitting 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 A-A in Figure 3. The sectional view, FIG. 5, is a perspective view of the eccentric cam.

In each of the above figures, the door head device of this embodiment is provided with an adjustment screw 2 and an eccentric cam 3 for adjusting the width in conjunction with a door head main body 1 in the upper part of the fitting.

The adjustment screw 2 is rotatably supported by the side wall 4 of the door neck main body 1 through a through hole 5, and is screwed into a gear portion 9 of an eccentric cam 3, which will be described later. The adjustment screw 2 has a tip 6 engaged with the inner wall of the door neck main body 1, and the neck is supported in the through hole 5, and both ends are supported to provide strong support.
However, only the neck may be supported on a cantilever. Further, the adjustment screw 2 is prevented from coming off from the through hole 5 by fitting a retaining ring 7 inside the side wall 4. This retaining ring 7 may be fitted and locked with a split pin or the like when the adjusting screw 2 is inserted into the through hole 5. 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 eccentric cam 3 has an externally toothed circular gear portion 9 and a projecting piece portion 10 projecting toward the inner wall side of the lintel groove 21, and is rotatably supported within the door neck main body. Third
In the case of the illustrated embodiment, the rotation center of the gear portion 9 is supported by a pin 11, and the above-mentioned adjustment screw 22 is screwed into this gear portion 9. By rotating the adjustment screw 2, the eccentric cam 3 is rotated, and the projecting width of the projecting piece 10 of the cam 3 is adjusted according to the lintel width.

As an example, the eccentric cam 3 has a configuration in which the gear part 9 is formed in a substantially semicircular shape with the pin 11 as the center point, and a semicircular protrusion with a larger diameter is attached to the back of the gear part 9. The portion 10 is provided eccentrically. When the projecting piece 10 has a semicircular shape, sliding contact with the inner wall of the lintel groove 21 can be made more smoothly. Further, since the rotation radius of the protruding piece 10 is made larger than the rotation radius of the gear part 9, the rotational movement of the protruding piece 10 can be increased relative to the rotational movement of the gear part 9. Above protruding piece 1
0 is the lintel groove 21 from the side passage hole 12 of the door head body 1.
The width of the door neck can be adjusted by protruding inward. Projection piece 1
The vertical width of 0 is formed to be somewhat close to the engagement length of the door head main body 1 with the lintel groove 21. Further, since the tooth surface of the gear portion 9 is curved, the threaded engagement with the adjustment screw 2 can be made even stronger.

The interior of the door neck body 1 described above includes the eccentric cam 3
It is formed with a space in which the adjustment screw 2 can be accommodated, and after the adjustment screw 2 is accommodated, the lid body 1 is placed on the top surface.
3 is applied. This lid body 13 is formed to have the same width as the door neck body 1 and is arranged to fit within the lintel groove 21. The door head main body 1 is an adjustment lever 2 of the upper stile 22.
3, and the lower surface part is fitted to a vertical stile (not shown). Door head body 1
Projecting piece 10 of eccentric cam 3 for width adjustment attached to
may be made to protrude from the front side of the door neck main body 1 as in the embodiment, or may be made to protrude from the back side.

Next, the assembly order of the above embodiment device will be explained. First, place the eccentric cam 3 inside the door neck body 1, insert the adjustment screw 2 into the through hole 5 provided in the side wall 4 of the door neck body 1, and screw the screw 2 into the gear part 9 of the eccentric cam 3. Then, the adjustment screw 2 and the eccentric cam 3 are supported on the door neck body 1, and the lid body 1 is attached to the upper surface of the door neck body 1.
3. After rotating the adjustment screw 2 and adjusting the width using the eccentric cam 3, insert a board into the recess 8 to prevent the adjustment screw 2 from rotating naturally due to sliding vibration of the shoji body. It is best to prevent the screw from rotating.

FIG. 6 is a cross-sectional view showing another embodiment, in which the basic structure consisting of the adjusting screw 2 and the eccentric cam 3 is substantially the same as the first embodiment, but the supporting structure of the eccentric cam 3 is different. . That is, a receiving groove 14 that matches the outer shape of the gear portion 9 of the eccentric cam 3 is formed in the door neck main body 1,
An eccentric cam 3 is fitted into the receiving groove 14 so that the cam 3 is rotatably supported on the door neck body 1. As the gear part 9 rotates, a projecting piece 10 provided eccentrically from the center point of the gear part 9 projects into the lintel groove 21 from the side opening 15 of the door neck main body 1. In addition, after the adjustment screw 2 is inserted into the long hole 16 formed in the door neck body 1, the retaining ring 1 is inserted to prevent it from coming off.
7 is fitted into the recess 8.

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 eccentric cam can be rotated and its projecting piece can be freely projected toward the inner wall side of the lintel groove. Since it can be moved backward, the width of the door neck can be freely adjusted while the fittings are attached to the lintel. Furthermore, since the width adjustment is carried out in a stepless manner by rotating the screws, more appropriate width 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 by rotating an eccentric cam by rotating a screw, the structure is simplified and the possibility of failure is reduced to the utmost.
