Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adjusting screw used for attaching a frame to an opening such as a door, a sliding door or a window in a house. The present invention also relates to a method of mounting a frame using the adjusting screw.

[0002]

2. Description of the Related Art Frames previously assembled into a three-sided or four-sided frame by vertical or horizontal frames are fitted into openings of doors, sliding doors, windows, etc. in a house, and are grounded using screws, nails or the like. Fixed to the structure. At this time, in order to facilitate the fitting of the frame into the opening, the inner dimension of the opening is provided to be larger than the outer dimension of the frame.

[0003] In the construction, after the frame is fitted into the opening, the vertical and horizontal levels of the frame are adjusted while the spacer is interposed between the base structure and the outer surface of the frame. Was fixed. Further, even when the vertical and horizontal levels are not obtained due to distortion of the structure at the time of construction of the foundation structure itself and after the construction, the construction is similarly performed while adjusting the vertical and horizontal levels of the frame.

[0004] However, even though the spacer is actually used as an appropriate spacer by combining the wood ends collected at the construction site, the work is not only troublesome but also troublesome.
There is a problem that the vertical and horizontal levels of the frame cannot be accurately set because fine adjustment is difficult.

In order to solve this problem, there has been proposed a construction method in which an adjusting screw is used for mounting the frame (Japanese Patent Laid-Open No. 3-16).
6481). According to this mounting method, an adjustment screw having an outward flange-shaped thin ring portion on the head side and a screw portion on the distal end side is used, the thin ring portion of the adjustment screw is fixed to the frame, and the screw portion is fixed. Is screwed into the opening to fix the frame to the opening, and the distance between the outer periphery of the frame and the inner surface of the opening is adjusted according to the screwing depth of the screw into the opening.

[0006]

However, according to this method of attaching the frame, when the adjusting screw is screwed into the frame, the thin ring portion is first screwed in after the screw portion is threaded. The frame is dug by the screwing, and the fixing strength of the thin ring portion to be screwed thereafter is reduced.

Further, if the vertical and horizontal leveling adjustments are repeatedly performed with the adjusting screw after the frame is attached to the opening, fragile damage occurs to the frame fixing the thin ring portion, and adjustment is difficult. Or, if it becomes impossible, or if a door or sliding door is installed in the opening after adjustment, the frame may be loosened due to impact, etc. There have been problems such as the formation of a gap between the structure and the airtightness, and the like.

[0008]

SUMMARY OF THE INVENTION Accordingly, the present invention is an improvement of the above-mentioned prior art adjusting screw, which facilitates vertical and horizontal level adjustment after the frame is attached to the base structure of the opening. It is firmly fixed to the frame without damaging the frame, and even if the adjustment is repeated, the frame is still not damaged, and the opening or closing of the door or sliding door provided in the opening may be hindered. It is an object of the present invention to provide a novel adjusting screw which does not cause a problem such as a decrease in hermeticity.

That is, the adjusting screw according to the present invention has (1)

The fixing screw is inserted into the seat hole of the frame so that the fixed seat is fitted and fixed in the seat hole, and the adjusting screw is further screwed in so that the screw at the tip is screwed into the pillar, and the frame is attached to the base structure. And the ring portion is fitted into the fixed seat.

[0012]

1 and 2 show an adjusting screw 1 according to an embodiment of the present invention. This adjustment screw 1 is a screw 1
0 and a fixed seat 20.

The screw 10 has a screw shaft 11 and a screw head 12 provided at one end thereof. The screw head 12 is provided with an insertion hole 13 into which the driver 2 (FIG. 3) is inserted.

The screw shaft 11 is provided with a ring portion 15 consisting of a plurality of rings 14 just below the screw head 12. The ring 14 is preferably formed to have an inverted trapezoidal cross section with the screw head 12 side as a plane and the lower side as an inclined surface, which facilitates screwing of the adjusting screw into the frame and temporarily screws the screw. The dropout after being dropped is effectively prevented.

At the lower end of the screw shaft 11, a screw portion 16 is provided. It is preferable that the outer diameter of the screw portion 16 be smaller than the outer diameter of the ring 14, so that the insertion trajectory of the ring 14 is larger than the screw trajectory of the screw portion 16. It is effective for prevention of slippage.

The ring portion 15 and the screw portion 16 are separated by a smooth surface portion 17 having a predetermined length. Here, the smooth surface portion 17 includes the ring 14 of the ring portion 15 and the screw portion 16.
A portion having a substantially smooth cylindrical surface which does not form a protrusion larger in diameter than the screw shaft 11 like the screw of FIG. To contribute to preventing the ring 14 from coming off, it is preferable that the outer diameter of the smooth surface portion 17 be smaller than the outer diameter of the ring 14.

Although not shown, the ring 15
In the above, the ring 14 can be provided so that the outer diameter thereof gradually increases from the screw portion 16 side toward the screw head 12 side. This facilitates the screwing of the screw portion 16 and the fitting of the ring portion 15.

The screw portion 16 of the screw 10 is screwed into the fixing seat 20. The fixed seat 2 has an inner diameter smaller than the outer diameter of the screw portion 16 and has longitudinal grooves 21 and 22 on its inner surface and outer surface, respectively. Since the fixed seat 20 is substantially cylindrical, and the inner and outer surfaces thereof are provided with longitudinal grooves 21 and 22 extending in the axial direction, the outer periphery of the fixed seat 2 can be deformed in a bellows shape by these longitudinal grooves. In addition, the diameter is increased by receiving side pressure due to screwing or fitting of the screw portion 16 or the ring portion 15 of the screw 10.

FIGS. 3 to 5 show a mounting method for fixing the frame body to the opening provided on the wall surface by using the adjusting screw 1 in which the screw portion 16 of the screw 10 is screwed into the fixing seat 20. It will be described with reference to FIG. The frame body is assembled between the base structures of the opening after being assembled in advance into a three-sided frame or a four-sided frame by a vertical frame, a horizontal frame, or the like. FIGS. A mounting procedure for fixing the column 3 to a pillar 4 as a base structure is shown.

A seat hole 3a into which the fixing seat 20 of the adjusting screw 1 is inserted is formed in advance from the inner surface side of the vertical frame 3 (FIG. 4). If necessary, a recess 3b having a larger diameter is provided for accommodating the screw head 12 of the adjusting screw. Seat hole 3
Although a is formed to a depth that does not reach the outer surface of the vertical frame 3, a screw hole into which the screw portion 16 of the adjustment screw 1 is screwed is provided in advance from the tip to the outer surface of the vertical frame 3. (Not shown).

Then, the tip of the driver 2 is screwed to the screw head 12.
The adjusting screw 1 is inserted into the seat hole 3 a of the vertical frame 3 while being fitted into the fitting hole 13 of the vertical frame 3. Since the fixed seat 20 attached to the tip of the adjusting screw 1 has a vertical groove 22 on its outer surface, the vertical groove 22 is seated by inserting the adjusting screw 1 into the seat hole 3a without rotating. It bites into the side surface of the hole 3a and is linearly guided by the
Is inserted into. Thereby, first, the fixing seat 20 of the adjusting screw 1 is fitted and housed in the seat hole 3a of the vertical frame 3. As described above, the fixed seat 20 is expanded in a bellows shape by the insertion of the screw portion 16, so that a strong lateral pressure is applied to the vertical frame 3 in a state where the fixed seat 20 is fitted and accommodated in the seat hole 3a. Fixed to

Further, by screwing the adjusting screw 1 while rotating it with the screwdriver 2, the screws 10 are sequentially screwed into the fixed seat 20 which is still fitted and accommodated in the seat hole 3a, and the screw portion 16 is Screw into 4. Thereby, the vertical frame 3 is fixed to the pillar 4. At this time, at least one ring 14 of the ring portion 15 of the adjusting screw 1 is fixed to the fixing seat 20.
The fixing seat 20 is further screwed into the inside and the diameter of the fixing seat 20 is further expanded in a bellows shape, so that the fixing state is further strengthened. That is, the fixed seat 20 is extremely firmly fixed to the seat hole 3a, and the ring 14 of the ring portion 15 is bite-fixed to the fixed seat 20. Therefore, even if the adjusting screw 1 is rotated in the loosening direction (counterclockwise) from this state, the ring portion 15 does not fall out of the fixed seat 20 and the relative positional relationship with the fixed seat 20 is maintained. Further, since the ring portion 15 merely idles in the seat hole 3a with the ring 14 biting, there is no damage to the vertical frame 3 around the seat hole 3a.

On the other hand, the screw portion 16 screwed into the column 4
When the adjusting screw 1 is rotated in a loosening direction, it gradually moves away from the pillar. In this manner, after the screw portion 16 is screwed into the column 4 to fix the vertical frame 3 to the column 4, the mounting position of the vertical frame 3 can be adjusted by loosening the adjusting screw 1.

The case where the horizontal adjustment is performed after the vertical frame 3 is attached to the pillar 4 has been described above. Similarly, the adjustment is performed after the horizontal frame is attached to the floor or ceiling foundation structure. By rotating the screw 1 in the loosening direction, adjustment in the vertical direction can be performed. In this way, by using the adjustment screw 1, the frame body can be attached to the base structure, and leveling in the horizontal and vertical directions after the attachment can be easily performed.

[0025]

By using the adjusting screw of the present invention,
The frame can be attached to the base structure, and leveling in the horizontal and vertical directions after the attachment can be easily performed.

In the adjusting screw of the present invention, the ring portion is accommodated in a fixed seat, and even if the screw is rotated to perform horizontal or vertical adjustment, the ring portion rotates within the fixed seat. It does not damage the frame because it is only damaged. Therefore, adjustment at the time of attaching the frame body to the opening,
Even if the adjustment is performed several times, such as the adjustment at the time of use after the mounting and the adjustment required according to the aging behavior of the frame, the frame is not damaged.

Moreover, since the fixing of the adjusting screw to the frame is performed through a fixing seat having vertical grooves on the inner and outer surfaces and capable of expanding in a bellows shape, the diameter of the adjusting screw is increased by screwing the screw portion and the ring portion. It is firmly fixed to the frame, and its fixing strength does not decrease even if the screws are loosened for adjustment.
