  In the conventional bracket with a collar as described above, since the base 12 and the cylindrical collars 13 and 14 are separate parts, it is necessary to perform the work of crimping the collars 13 and 14 on the base 12. In addition, since it is necessary to prepare the collars 13 and 14 made of stainless steel for the fastening portions, the parts cost and the management cost are required, and the manufacturing cost increases.

  Therefore, in view of the above-described situation, the present invention intends to provide a bracket with a collar that can reduce the manufacturing cost by forming a shape that can be integrally formed by sheet metal pressing.

  In order to solve the above problems, the bracket with a collar according to the present invention is attached to a shoji or frame body of a composite sash, and a plate portion for surface contact that follows the inner surface of a resin sash or a wooden sash, and the plate portion for surface contact And a bracket with a collar formed of a plurality of collar portions extending in a direction opposite to the bending direction of the bent plate portion perpendicular to the surface contact plate portion. The collar portion is a wall body having an arc-shaped cross section parallel to the surface contact plate portion, and has a shape having an opening on the side surface, and the surface contact plate portion and the wall body. By providing the legs to be connected, they are integrally formed by sheet metal pressing.

According to such a configuration, the collar portion is formed as a wall having an arc-shaped cross section parallel to the surface contact plate portion, and has an opening on the side surface, and the surface contact plate portion and the wall body. Since the leg part which connects is provided, the bracket with a collar can be integrally formed only by sheet metal pressing.
Therefore, it is not necessary to crimp the collar like a conventional bracket with a collar, and it is not necessary to prepare a stainless steel collar for the fastening part. Therefore, the manufacturing cost can be reduced.

Here, it is preferable that the indoor side end surfaces of the plurality of collar portions are in contact with the surface contact plate portion.

The accuracy of the bracket with the collar can be secured and the strength is improved.

In addition, the plurality of collar portions are spaced apart in the left-right direction toward the outdoor direction, and the plane including the sides on the inner diameter side of both end surfaces of the arc-shaped wall body that is long in the indoor / outdoor direction is inclined from the horizontal plane. Thus, it is preferable that the opening is formed.
According to such a configuration, the opening is formed such that a plane including the inner diameter side edges of both end faces of the wall body having an arcuate cross section parallel to the surface contact plate portion is inclined from the horizontal plane. Therefore, since the rigidity around the left-right axis of the bracket is higher than that in which the opening is formed so that the flat surface is a horizontal surface, the effect of suppressing the tilt of the bracket around the left-right axis is increased.

Further, it is more preferable that the number of the collar portions is two, the openings face each other inward in the left-right direction, and the inclination angles of the two planes are different from each other.
According to such a configuration, the manufacturing cost can be further reduced by the minimum number of collar portions, the openings of the two collar portions face inward in the left-right direction, and Since the angle of inclination with the horizontal plane is different, the rigidity around the left and right axis and the vertical axis of the bracket is increased, so the effect of suppressing the tilting around the left and right axis and the vertical axis of the bracket is increased. .

  According to the bracket with a collar according to the present invention as described above, the bracket with a collar can be integrally formed only by sheet metal pressing by the collar portion having the above-described shape. The fastening work is not necessary, and it is not necessary to prepare a stainless steel collar for the fastening part, and the number of assembling steps, the part cost and the management cost can be reduced, so that the manufacturing cost can be reduced.
