JP4486285B2 - Method for adjusting the height of a sag stopper in a sag stopper for an open shoji - Google Patents

Description

[0001]
[Industrial application fields]
The opening shoji is hinged on the bottom edge of the window frame and receives the load on the door tip side at the hinge part, so when the door tip side is in a sag and closed state, it absorbs the sag. A sag stopper is provided on the side to perform the closing operation smoothly.
[0002]
The present invention relates to a method for adjusting the height of a sag stopper in such a sag stopper of an open shoji.
[0003]
[Prior art]
Needless to say, a sag stopper is provided on the side of the shoji, and a sag stopper where the roller of the sag stopper contacts the upper surface is provided on the lower frame of the window frame.
[0004]
[Problems to be solved by the invention]
In the conventional example, since the thickness of the sag stopper that is placed and fixed on the lower frame of the window frame is constant, adjustment of the contact degree (climbing condition) of the roller of the sag stopper that rides on the sag stopper is possible. There are disadvantages that cannot be made, and as a result, there is no means for dealing with defects in machining accuracy and problems with hitting (climbing) with time.
[0005]
The present invention was created in view of such a situation.
[0006]
[Means for Solving the Problems]
An anti-sagging device for an open shoji that is provided with a sag stopper on the side of the shoji, and a sag stopper that the roller of the sag stopper contacts the upper surface is provided on the lower frame of the window frame. These component parts are stacked on each other and fixed to the window frame lower frame in a detachable manner for adjustment.
[0007]
【Example】
The drawings show an application example of the method for adjusting the height of the sag stopper in the sag stopper of the open shoji according to the present invention, FIG. 1 is a cross-sectional view of the main part, FIG. 2 is a cross-sectional view, and FIG. FIG. 4 is a perspective view of a component part of the sag stopper receiver, and FIG. 5 is a cross-sectional view of a main part in a state where the height of the sag stopper receiver is changed.
[0008]
In the embodiment, the present invention is applied to a double folding folding sash, wherein 1 is a lower arm of the shoji 2, and the lower arm 1 is provided with a recessed portion 3 on its lower surface, and the sag stopper 4 is provided in the recessed portion 3. The main frame 5 is engaged and fastened, and a sag stopper 7 is provided on the lower frame 9 of the window frame 8 to ride the roller 6 of the sag stopper 4.
[0009]
The sag stopper 4 includes a horizontal piece 5a, side pieces 5b, 5b provided opposite to both sides of the horizontal piece 5a, and one side of the side pieces 5b, 5b between the side pieces 5b, 5b. The roller 6 is pivotally attached to the other end side corresponding to the one end of the side piece 5b, 5b of the main frame 5 which is composed of a vertical piece 5c connected to the horizontal piece 5a. A mounting screw 10 configured and penetrated through the horizontal piece 5a is screwed into the lower collar piece 1a and attached to the lower collar 1.
[0010]
In the embodiment, the sag stopper 7 is formed by appropriately stacking the first to third component pieces 7A, 7B, 7C, and a pair of through-holes 11, provided in the component pieces 7A, 7B, 7C. 11, 11 a, 11 a, 11 b, 11 b are passed through the fixing screw 12 and screwed into a screw hole 13 provided in the window frame lower frame 9 to be tightened. The height of the sag stopper 7, that is, the roller 6 However, FIG. 1 shows the case where the height is adjusted using all of the first to third component pieces 7A, 7B, and 7C. FIG. 5 shows a case where the height is adjusted using the first component piece 7A and the second component piece 7B.
[0011]
The first component piece 7A is provided with through holes 14a and 14b that engage with the projections 13a and 13b provided in the through holes 11, 11, the second component piece 7B, and the third component piece 7C, and the upper surface on the front end side is The roller 6 is configured by a flat plate provided with a tapered surface a for facilitating getting on.
[0012]
In addition, the second component piece 7B engages with the through holes 11a and 11a and the through holes 14a provided in the first component piece 7A in a flat plate whose top surface matches the shape of the bottom surface of the first component piece 7A. The projection 13a and the third component piece 7C are provided with a through hole 15b for engaging the projection 13b.
[0013]
The third component piece 7C is configured by providing the through holes 11b and 11b and the projections 13b and 13b on a flat plate whose upper surface matches the lower surface of the second component piece 7B.
[0014]
And according to the degree of sagging of the shoji 2, the first component piece 7A alone or the first component piece 7A is used in combination with one or both of the second component piece 7B and the third component piece 7C, Although not shown in the case of the first component piece 7A alone, the first component piece 7A is placed on the lower frame 9, and the fastening screw 12 is screwed and tightened into the screw hole 13 through the through hole 11. Use.
[0015]
When adjusting the height of the sag stopper 7 between the first component piece 7A and the second component piece 7B, the projection 13a provided on the second component piece 7B is engaged with the through hole 14a provided on the first component piece 7A. The two structural pieces 7A and 7B are overlapped with each other, and the fastening screws 12 are sequentially passed through the through holes 11 and 11a and screwed into the screw holes 13 provided in the lower frame 9 (FIG. 5).
[0016]
In addition, on the lower surface side of the second component piece 7B in which the first component pieces 7A are combined as described above, the projection 13b is engaged with the through holes 15b and 14b provided in the component pieces 7A and 7B, thereby forming the third component. The pieces 7C are combined, and the fixing screws 12 are sequentially passed through the through-holes 11 and 11a and 11b and screwed into the screw holes 13 provided in the lower frame, so that the three-piece pieces 7a, 7b and 7C are used. The height of the receiver 7 is adjusted.
[0017]
When assembling the constituent pieces 7a, 7B, and 7C, it is not necessary to use the engaging relationship between the projections 13a and 13b and the through holes 14a, 14b, and 15b as in the embodiment. , 7B, 7C are firmly assembled with each other.
[0018]
【The invention's effect】
Since the present invention is configured as described above, the height of the sag stopper can be easily adjusted.
