Description

  The present invention relates to a member for facilitating installation of a ceiling air diffuser installed on a ceiling in order to uniformly diffuse air from an air conditioner into a room.

  The conventional method of installing a ceiling diffuser is to fix the tap L-shaped metal fittings provided with female screws at three locations inside the existing duct to be installed, and to attach to the outer cone of the ceiling diffuser, providing a long hole. The long hole of the long hole L-shaped metal fitting is installed on the ceiling by aligning the position of the female screw of the tap L-shaped metal fitting and tightening with a bolt from the long hole side.

  There are two types of ceiling diffusers: square, square, and quadrangular. When installing a quadrangular ceiling diffuser, it is necessary to arrange the sides of the quadrangle so that they are parallel to the indoor wall. It is necessary to adjust the position of the tap L-shaped bracket.

  FIG. 8 is a perspective view showing each component and its positional relationship for attaching a circular sealing diffuser to an existing duct. In FIG. 8, reference numeral 81 denotes an object to which a ceiling diffuser is attached, an existing duct formed of iron, 82a, 82b, and 82c are tap L-shaped fittings, and 83a, 83b, and 83c are for attaching a tap L-shaped fitting to the duct. , 84 is a cone outside the ceiling diffuser, 85a, 85b and 85c are long hole L-shaped fittings attached to the cone outside the sealing diffuser, and 86a, 86b and 86c are bolts for fastening the tap L-shaped bracket and the long hole L-shaped bracket. It is.

  FIG. 5 is a perspective view showing a method for specifying the attachment position when attaching the tap L-shaped brackets 82a, 82b, 82c to the existing duct 81. FIG. The procedure is to insert the sealing diffuser outer cone 84 temporarily inside the existing duct 81 and hold it with one hand, while attaching it to the sealing diffuser outer cone 84 in advance. , 85c are indicated on the inner surface of the existing duct 81 by markings 50a, 50b, 50c. In this case, since the sealing diffuser is circular, it is not necessary to perform marking according to the direction of the wall.

  FIG. 6 is a perspective view showing a method for specifying the position of the tap L-shaped metal fitting when the rectangular ceiling diffuser is attached to the existing duct 81. In this case, since the ceiling diffuser has a straight side, it is necessary to arrange the side in parallel with the wall surface.

  The procedure is as follows. First, a rectangular sealing diffuser outer cone is temporarily inserted inside the existing duct 81, and the side of the anemone-shaped outer blowing cone 60 is parallel to the nearest wall surface of the room. While rotating the diffuser outer cone 60 and holding it with one hand in a state adjusted to an appropriate angle, the position of the long hole L-shaped metal fitting 85 mounted on the sealing diffuser outer cone 84 in advance is set to the existing duct 81. It is indicated by markings 50a, 50b, and 50c on the inside.

  FIG. 7 is a perspective view showing a state in which the tap L-shaped brackets 82a, 82b, and 82c are attached with the mounting screws 83a, 83b, and 83c based on the markings 50a, 50b, and 50c in the following procedure. Based on the positions of the markings 50a, 50b, and 50c inside the existing duct 81, the tap L-shaped brackets 82a, 82b, and 82c are fixed to the three locations with the mounting screws 83a, 83b, and 83c, respectively. As shown in Fig. 2, the bolts 86a, 86b, 86c are inserted into the long holes of the long holes L-shaped metal fittings 85a, 85b, 85c, and the male screws of the bolts 86a, 86b, 86c are tapped. The sealing diffuser is installed and fixed to an existing duct by being screwed into the female threads of the L-shaped brackets 82a, 82b, and 82c.

  In this way, in the installation process of the conventional ceiling diffuser, it is necessary to adjust the installation direction of the ceiling diffuser at the installation site, and the work is performed on a stepladder or workbench, ensuring safety and the work itself. There is room for improvement from the viewpoint of efficiency improvement.

  Accordingly, an object of the present invention is to provide a member that can eliminate the positioning marking work by temporary insertion of the outer cone when the sealing diffuser is attached and can improve the attachment accuracy.

  In order to solve the above-mentioned problems, the present invention manufactures a ring corresponding to the size of the ceiling diffuser in advance, and attaches a tap L-shaped metal fitting at a required position of the ring. Especially in the case of a square ceiling diffuser, the existing duct Further, as a result of studying the adjustment of the position of the tap L-shaped metal fitting based on the position of the through hole for screwing the ring.

  In other words, the present invention relates to a sealing diffuser mounting ring having at least one L-shaped bracket for mounting a sealing diffuser and four through holes approximately every 90 ° of the circumference of the ring for mounting to a duct. The sealing diffuser mounting ring is characterized in that the position of the hole is adjusted so that it can also be used as a marker in the mounting direction of the sealing diffuser.

  Further, the present invention is a duct / sealing diffuser joining structure, wherein the sealing diffuser mounting ring is interposed between a duct and a ceiling diffuser.

  In the installation process using the ring according to the present invention, for example, a through hole is provided so that a line passing through the center of a pair of opposed through holes is parallel to the surface of the wall, and the reference line As described above, by adjusting the position of the tap L-shaped bracket, it is not necessary to adjust the direction of the square ceiling diffuser at the installation site.

That is, according to the present invention, the following effects can be obtained.
(1) Since the ring is mounted at the position where the tap L-shaped bracket is specified for each size of the ceiling diffuser, the ring is secured directly to the existing kut without considering the position. Can be attached.
(2) When attaching the square sealing diffuser, for example, four through holes are provided every 90 ° of the circumference of the ring, and the straight lines passing through the opposing through holes are orthogonal to each other. As a reference, the square side of the square ceiling diffuser can be made parallel to the wall surface of the chamber to be installed by directly screwing the ring to the existing duct.
