Description

[Detailed Description of the Invention] This invention relates to an eccentric cam for stabilizing a fitting, which allows the swallowing width of a metal fitting to be inserted into a groove of a lintel to be adjusted according to the width of the groove.

Due to the lack of high-quality wood in recent years, interior fittings have come to be constructed using extruded metal shapes, but metal fittings cannot be easily adjusted for installation by scraping them off like wooden fittings. Therefore, as the groove width of Shikimoi varies depending on the region and type of building,
It was a hassle to have to manufacture several types of door necks and steady rests depending on the width of the recess. Furthermore, even if door necks and the like were selected depending on the width of the groove in the lintel, it was not possible to completely prevent the swinging of the fittings due to manufacturing errors in the door neck and groove.

Therefore, this idea was developed by pivoting an eccentric cam on the upper swallowing part of the fitting that is inserted into the groove of the lintel, and by protruding a part of the cam outward from the swallowing part to prevent the fitting from swinging. This is what I did.

Next, the structure of the eccentric cam according to the present invention will be explained with reference to drawings of embodiments. A through hole 3 is bored in the center of the cam body 2 which has a disc shape, and a through hole 3 is formed in several places on the outer circumferential surface 5. Notches 4 are provided at equal intervals, and between the notches 4 and the adjacent notches 4', an arc-shaped eccentric part 6 with the through hole 3 as the center is provided with a radius from the center to the outer circumferential surface 5 of the eccentric part. For example, when forming the notches 4 at intervals of 40 degrees in the cam body 2 with a radius r of 6.2 mm, the first
The radius r1 of the eccentric part 61 is 6.5 mm, and the second eccentric part 62
The radius r2 of the third eccentric part 63 is 7 mm, and the radius r3 of the third eccentric part 63 is
The radius r4 of the fourth eccentric portion 64 is 8 mm.

Since the eccentric cam of the present invention has the above-mentioned structure, it is attached to the upper horizontal beam 7 of the fitting, specifically, the upper part has the swallowing part 71 to be inserted into the groove H of the lintel G, and the lower part has the swallowing part 7.
1, or the adjustment bar 7B that can be protruded and retracted from the inside of the upper stile 7A in the outer circumferential direction, the end of the side wall 7b above the connecting wall 7a of the swallowing part 71. An opening 17 is provided by cutting out a part of the side wall 7b, and the eccentric cam 1 of the present invention is fixed to the upper part of the connecting wall 7a with screws B. Specifically, the outer circumferential surface 5 forming the eccentric cam 1 is Within, the minimum radius r
In a state where the outer circumferential surface 5 of is directed toward the opening 17,
The outer circumferential surface 5 is fixed so as not to protrude outward from the opening 17, and the eccentric portion 6 of the cam 1 is adjusted so as to protrude outward from the opening 17 according to the groove width S of the lintel G. . The eccentric cam 1 can be fixed by directly screwing a screw B into the horizontal stile connecting wall 7a through the through hole 3, or by drilling a through hole 8 in the horizontal stile connecting wall 7a at the position where the opening 17 is formed, and fixing it on the inner periphery. The back plate 9 having a female screw hole 19 is brought into contact with the connecting wall 7 through the through hole 3 of the cam 1.
It is inserted into the through hole 8 of a, and screwed into the female screw hole 19 of the back plate 9 to fix it, so to adjust the eccentricity according to the groove width S of the lintel G. , First, remove screw B that fixes cam 1.
loosen it to the extent that it is possible to rotate it, then gradually increase the radius r
The eccentric portions 61, 62, 63 of the cam 1 where the
64 according to the groove width S of the lintel G, and rotate it toward the opening 17 of the horizontal stile 7.
After the selected eccentric portion 6 of the cam 1 is made to protrude outward from the opening 17, the loosened screw B is tightened and fixed to complete the adjustment. That is, if the first eccentric part 61 of the eccentric cam 1 is fixed toward the opening 17, the eccentric part 61 will be 0.3 mm away from the opening 17.
If the second eccentric part 62 is fixed toward the opening, the eccentric part 62 will protrude outward from the opening 17.
Projects outward by 0.8mm. Hereinafter, if the third eccentric part 63 is directed toward the opening 17, the third eccentric part 63 will be directed toward the opening 17.
It protrudes 1.3 mm outward from 7, and the fourth eccentric part 64
When facing the opening 17, the eccentric portion 64 protrudes 1.8 mm outward from the opening 17.

Note that the specific implementation of the invention is not limited to the above embodiment, and the screw B inserted from the through hole 3 of the eccentric cam 1 into the through hole 8 of the horizontal stile connecting wall 7a can be inserted into the vertical stile. It can also be fixed to the cam 1 by screwing it into the block 18 that is fitted across the horizontal stile 7, and the radius r from the center to the outer circumferential surface 5 of the eccentric part is determined by the number The same purpose can be achieved even if the number of eccentric parts 6 is increased by a constant value or by an appropriate increase. Changes may be made as appropriate as long as they do not violate the gist of the invention.

Therefore, in the eccentric cam of the present invention, the radius from the center to the outer peripheral surface of the eccentric part is increased by several mm at regular intervals, so that the eccentric part protrudes in a step-like manner. If it is attached to the stile, the eccentric part of the cam can be adjusted to protrude outward from the opening of the fitting swallowing part according to the width of the concave groove of the lintel, thereby preventing the fitting from swinging laterally during opening and closing. Moreover, when adjusting the eccentric part of the cam toward the opening of the side stile, even if the eccentric part is fixed in a slightly different direction, the eccentric part will form an arc with the same radius over the appropriate range, allowing accurate eccentric adjustment. can be achieved. As a result, the eccentricity adjustment becomes very easy, and the adjustment means is simply to loosen the screw, rotate the cam, direct the eccentric part of the cam toward the side stile opening, and tighten the loosened screw. The eccentric block of the present invention has a remarkable practical effect as an installation adjustment tool for fittings that are inserted into the grooves of shikimoi, which vary depending on the region and type of building, as installation and eccentric adjustment operations are easy. It is something to play.
