Description

[Detailed explanation of the idea] This invention relates to the mounting structure of the hinge and the cushioning material.

Conventionally, hinges are used to pivotally support hinged doors, and the closed position of the hinged door is stopped by pressing against the airtight gasket between the hinged shoji and the opening frame. Although it is possible to use such a hinge with the sole function of supporting a swinging door for a folding door shoji and a folding door shoji, if airtightness is required between the folding door shoji and the folding door shoji, there is a separate means to ensure airtightness. When the folding door shoji is closed, or when the two shoji of the folding door shoji rotate in the opposite direction around the jointed hinge, the folding door It is necessary to prevent the pivot points of the shoji and the folding door shoji from bending in the opposite direction to the side on which they should originally fold.
However, conventional hinges cannot brake the movement of the folding door shoji in this direction, so the force causes the edge of the folding door shoji to collide, causing the hinge to receive excessive force and cause the hinge to This will shorten the lifespan of the product and, in extreme cases, cause damage.

In addition, in the case of such hinges, it is necessary to separately measure the airtightness between the folding door shoji.

This invention was devised in view of the above-mentioned problems with the conventional hinges, and the purpose is to provide a hinge with an airtight function and a shock-reducing function.

This invention is a folding door shoji that is pivotally connected with a hinge, and a cushioning material is arranged between the end faces of the opposite stile side to which the hinge is attached. Regarding this, the hinge attachment part is fixed by being biased to one side in the internal and external direction of the vertical stile side end surface of the folding door shoji, and the cushioning material is in contact with the hinge attachment part of the vertical stile side end surface of the folding door shoji. Outside the range of the fixed part in the width direction, the buffer part that is held between the end faces of the folding door shoji when the folding door shoji is closed overlaps with the mounting part of the hinge and is fixed to the folding door shoji. This is a hinge and cushioning material mounting structure characterized by integrally providing a mounting portion.

Embodiments of this invention will be described below with reference to the drawings. FIG. 1 is a plan view of an embodiment of the hinge of this invention, and FIG. 2 is a side view of FIG. 1. The shaft 1 is rotatably fitted into the center hole of the boss parts 2 and 3,

That is, with respect to the width direction of the hinge and the stile-side end surfaces of the folding door shoji A, B, the hinge attachment parts 5, 6 are attached in the inner and outer directions of the stile-side end surfaces of the folding door shoji A, B, as described below. The cushioning material 1 is biased to one side and fixed in contact with the
1 is folded with the folding door shoji A, B closed outside the area in the width direction of the part where the hinge mounting parts 5, 6 of the stile side end face of the folding door shoji A, B are abutted and fixed. A buffer part 11b which is held between the stile-side end surfaces of the door shoji A and B and a mounting part 11a which is fixed to the folding door shoji A and B by overlapping the hinge mounting parts 5 and 6 are provided integrally. ing.

A mounting hole 12 is provided in the mounting portion 11a of the cushioning material 11, which is countersunk to match the small screw hole 8, and the mounting portion 11a has the same longitudinal dimension as the mounting portions 5 and 6. The buffering portion 11b of the cushioning material 11 excluding the mounting portion 11a may be made to match the length of the mounting portions 5 and 6, or may be larger than the longitudinal dimension of the mounting portions 5 and 6 in order to maintain the necessary buffering capacity.

When measuring the airtightness between the shoji screens using the buffer section 11b, the buffer section 11b may have the length of the vertical stile of the shoji screen, as will be explained later.

To connect the folding door shoji A and B shown by two-dot chain lines with the hinge of this invention, attach the mounting parts 5 and 6 to the vertical end faces of the folding door shoji A and B, respectively, in the same way as with a normal hinge. The countersunk machine screws 13 are inserted into the mounting holes 7 and 9 in contact with each other and screwed into the female threads of the vertical frames of the folding door shoji A and B, respectively, to pivotally attach the folding door shoji A and B.

Next, attach the cushioning material 11 to the folding door shoji B as shown in Figure 1.
The vertical stile side end face of the folding door shoji B comes into contact with the mounting part 5 of the hinge, and the machine screw 14 is inserted through the mounting hole 12 and the small screw hole 8 to be screwed and fixed to the vertical stile of the folding door shoji B. At this time, the portion of the cushioning material 11 that contacts the mounting portion 5 and the end surface of the folding door shoji B on the stile side may be fixed with an adhesive.

FIG. 4 shows an embodiment in which the cushioning material 11 also serves as an airtight packing. As shown by the two-dot chain line, the buffer portion 11b of the buffer material 11 is equal to the total length of the vertical stile of the folding door shoji A and B, and is fixed to the side end surface of the vertical stile of the folding door shoji B. It can come into contact with the vertical stile. The entire hinge of this invention is attached to the upper and lower sides of the folding door shoji A and B, as indicated by the reference numeral 10, and the cushioning material 11 is made integrally. This cushioning material may be divided into two parts and connected between the upper and lower hinge joints 10.

In the embodiment shown in FIG. 1, the cushioning materials 11 are assembled separately, but the mounting portion 5 and the mounting portion 11 of the cushioning material 11 are
a refers to adhesive or if the cushioning material 11 is made of rubber, it is attached by vulcanization, all the mounting parts 5 are provided with small screw holes 8, and the mounting part 11a of the cushioning material 11 is provided with countersunk mounting holes 12. are provided to match the small screw holes 8.

If the cushioning material 11 is used only for cushioning purposes, it should be the same length as the mounting parts 5 and 6, or the total length should be adjusted depending on the buffering capacity, and if it also serves as an airtight material, it should extend to both sides of the mounting parts 5 and 6. let Further, as shown in FIG. 4, hinges may be provided at the top and bottom and integrally provided. In this case, there are advantages that the hinge attachment position is automatically determined for a standard product and that it is suitable for mass production.

Next, an embodiment of the buffer material 11 will be described. FIG. 5 shows a cross section of the buffer material 11.
In the figure, in a free state, a hollow portion 11b is formed in the center of the buffer portion 11b, the hollow portion 11b being larger than the gap between the vertical frames of the folding door screens A and B.

When the hinge is pressed by the hinge shaft 1, the load is directly applied to the pivot point of the hinge. On the other hand, when the folding doors A and B become flat and attempt to rotate in the opposite direction, the impulse is absorbed by the cushioning material 11. This is because the impulse is determined by the moment of inertia of the folding doors A and B and the speed at which they rotate. Therefore, the longer the stroke over which the cushioning material 11 is pressed by the vertical frame of the folding doors A and B, the better. By providing an appropriate hollow portion 15 as shown in FIG. 5, the hinge shaft 1, boss 2,
The force applied to 3 can be reduced.

FIGS. 6 and 7 are cross-sectional views of other embodiments in which the cushioning material also serves as an airtight material. In the example shown in FIG. 6, chevron-shaped protrusions are arranged in parallel and provided in the buffer portion 11b of the buffer material 11, and the chevron-shaped protrusions perform both airtightness and buffering functions.

In the case shown in FIG. 7, the buffer portion 11b of the buffer material 11
In a free state, an airtight fin 11c and a buffer end 11d are provided as shown by the two-dot chain line, and the fin 1 is lower than the surface connecting the mounting surface 5a and the buffer end 11d.
1c stands out. Thus, folding door shoji A,
Good airtightness when installed on B, and when the folding door shoji A and B are on one plane, the position is at the buffer end 11
It is well determined by d.

As described above, the effect of each embodiment is that when the folding door shoji A and B rotate so that they are on one plane, the buffer part 11b of the buffer material 11 comes into contact with the stile-side end surface of the folding door shoji A and B. When the shock absorbing material is airtight, the space between the folding door shoji A and B is airtight.

FIGS. 8 and 9 each show another embodiment of this invention. In FIG. 8, the cushioning material 11 is attached to the mounting portion 5.
The buffer material 11b is sandwiched and attached between the folding door shoji A and the folding door shoji B, and the buffer material 11b is sandwiched and pressed between the folding door shoji A and the folding door shoji B. In FIG. are clamped and fixed between the folding door shoji A and B and the mounting parts 5 and 6, respectively, and the buffer part 1
1b is pressed together by the vertical frames of folding door shoji A and B.

In these embodiments as well, the buffer portion 11b may be provided with a hollow portion 15 as in the embodiment shown in FIG. 5, or may be provided with a chevron-shaped protrusion as shown in FIG. In this case, in FIG. 8, the chevron-shaped protrusion is provided facing the folding door shoji A, but in FIG. 9, it is provided at the portion where the buffer portions 11b of the buffer material 11 come into contact with each other. An airtight fin as shown in FIG. 7 may also be provided. Note that the length of the cushioning material 11 can be freely selected depending on the purpose.

As mentioned above, according to the hinge of this invention, the cushioning material is combined with or integrated with the hinge part, and the impact force due to the rotational force between the two folding door shoji is absorbed, so the metal No excessive force is applied to the hinges without making the sound of metal hitting. Furthermore, since the pivot point of the hinge and the buffer part of the buffer material are separated from each other in the inner and outer directions, the load capacity of the buffer part is large and the load conditions for obtaining the durability of the buffer material are good. The buffer section can also create an airtight seal between the two folding door shoji screens. Since the hinge attachment part and the cushioning material attachment part can be installed overlapping each other,
The cushioning material is positioned and attached at the same time as the hinge is positioned and attached. Furthermore, since the attachment surface of the cushioning material to the folding door shoji is large and the abutting position of the cushioning part is constant, stability is good. If the mounting part of the hinge and the mounting part of the cushioning material are fixed together in advance, the cushioning material has an airtight function at the same time as the hinge installation of this invention. Because it is attached to the machine, the process is omitted, and the installation is quick and the management of parts is easy.
