Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a mounting bracket for a ventilation port frame used when mounting a ventilation port frame forming an air outlet or an air inlet on a ceiling, a wall surface, or the like. It is a thing.

(Prior Art) Conventionally, when the ventilation frame is mounted on a ceiling, a wall surface, or the like, a mounting bracket 1 as shown in FIG. 1 is mounted on a duct fixed to the ceiling, the wall surface, or the like with screws or the like. Next, as shown in FIG. 2, the ventilation port frame 2 was attached to the mounting member 1 with the screw 3, and the ventilation port frame 2 was mounted on the ceiling, the wall surface or the like.

(Problems to be solved by the invention) When attaching the ventilation hole frame 2 using the conventional mounting bracket 1, the mounting bracket 1 is attached to the duct and the ventilation hole frame 2 is attached to the mounting bracket 1. It took a long time for the mounting work. Further, since the driver is inserted from the front opening of the ventilation frame 2 and the screw 3 is pushed into the screw fixing hole 4 of the fitting 1 attached to the duct, the mounting work is extremely troublesome.

The present invention has been made in view of such problems, and an object of the present invention is to attach a ventilation hole frame in a short time and to attach the ventilation hole frame that can easily perform the mounting operation. It is intended to provide metal fittings.

(Means for Solving the Problems) In order to achieve the above-mentioned object, a mounting bracket for a ventilation port frame according to the present invention comprises an upper plate piece portion which is relatively thick and has rigidity,
A key-shaped groove having a relatively thin wall that is elastic and bendable, and that is composed of both side plate pieces that are widened downward and that has elongated holes formed in the bottom surface on both sides of the upper plate piece. A mounting hole for a ventilation port frame in which a fastening plate having a screw hole formed in this key groove is slidably inserted, and the long hole of the sliding plate provided in the screw ventilation port frame. , Through the elongated hole of the upper plate piece of the mounting bracket, and screwed into the screw hole of the fastening plate, to mount the mounting bracket to the ventilation frame, and attach the ventilation frame with the mounting bracket to the side plate piece. A ventilation opening characterized in that the ventilation opening frame is attached to the duct by bending it and inserting it into a duct fixed to the ceiling, wall surface, etc., expanding the side plate piece to make it impossible to escape, and tightening the screw. It is a metal fitting for the frame.

(Operation) Ventilate the mounting bracket by passing the screw through the long hole of the sliding plate provided in the rectangular frame of the vent frame and the long hole of the top plate of the mounting bracket and screwing it into the screw hole of the fastening plate. Attach to the mouth frame.

Next, insert the ventilation frame with the mounting bracket attached through the opening of the duct fixedly installed on the ceiling, wall surface, etc., and the side plate piece of the mounting bracket contacts the bent portion of the duct to bend the arm, and When the vent hole frame is pushed in, the lower end of the side plate piece separates from the bent portion, the side plate piece expands, and the lower end of the side plate piece enters the lower groove of the duct. Finally, if the screws are tightened, the ventilation frame is attached to the duct and can be mounted on the ceiling, wall surface, or the like.

Embodiment An embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 3, the mounting member 5 of the present invention comprises an upper plate piece 6 and side plate pieces 7 and 8, and the side plate pieces 7 and 8 are spread downward. Further, the upper plate piece portion 6 is relatively thick and has rigidity, and the side plate piece portions 7 and 8 are relatively thin and elastic, so that the arm can be bent. Key-shaped grooves 9 are formed on both sides of the upper surface of the upper plate piece 6, and elongated holes 10 are formed on the bottom surface of the key-shaped grooves 9. Then, a fastening plate 12 having a screw hole 11 is inserted into the key-shaped groove portion 9 so as to be slidable. In order to prevent the fastening plate 12 from coming out of the key groove portion 9, both side portions of the key groove portion 9 are crushed, and the heights of both side ends of the key groove portion 9 are set to the thickness of the fastening plate 12. As less than. The side plate pieces 7 and 8 have a lower end portion 13 which is slightly thicker than other portions and has strength.

As shown in FIGS. 4 to 8, the ventilation port frame 14 mounted on the ceiling, wall surface, etc. has a rectangular frame part 15 and a frame side part 16,
The rectangular frame portion 15 has a plurality of blades 18 supported by a bracket 17. Further, in order to mount the ventilation frame 14, a sliding plate 20 which is slidable along the guide groove 19 of the rectangular frame portion 15 is provided.
1 is formed.

As shown in FIG. 8, the mounting member 5 is placed so as to cover the rectangular frame portion 15 of the ventilation port frame 14, and the screw 22 is passed through the long hole 21 of the sliding plate 20 to make the length of the mounting member 5 longer. Through hole 10,
It is attached to the ventilation port frame 14 by being screwed into the screw hole 11 of the fastening plate 12. This screw 22 is also the ventilation frame 1
Although the screwdriver is inserted from the front opening 23 of 4 and screwed, it is not easily screwed after the mounting bracket 5 is mounted on the duct fixed to the ceiling, wall surface or the like, and therefore the mounting work is extremely easy.

Next, as shown in FIG.
4, a bent portion 25 is formed, and the vent frame 14 having the mounting bracket 5 attached thereto is brought close to the opening 24 of the duct 26 fixedly mounted on the ceiling, wall surface, etc., as shown in FIG. 9 (b). Opening 24
, The side plate pieces 7 and 8 of the mounting member 5 come into contact with the bent portions 25 and bend the arms, and when the ventilation frame 14 is pushed in, the side plate portions 7 and 8 are inserted as shown in FIG. 9 (c). The lower end portions 13 of the piece portions 7 and 8 are separated from the bent portion 25, the side plate piece portions 7 and 8 are expanded, and the lower end portion 13 enters the lower end groove portion 27 of the duct 26. Finally, the frame side portion 16 of the ventilation port frame 14 and the duct 26
If the screw 22 is tightened so that the lower end groove portion 27 of the mounting bracket 5 and the lower end portion 13 of the side plate pieces 7 and 8 of the mounting bracket 5 come into contact with each other, the ventilation frame 14 is mounted on the duct 26 and mounted on the ceiling, wall surface, or the like. To be done. As described above, the work of attaching the ventilation port frame 14 to the duct 26 is extremely easy because the ventilation port frame 14 is simply pushed through the opening 24 of the duct 26. Finally, the work of tightening the screw 22 is also only the tightening of the screw 22 already attached to the ventilation frame 14, so it is quite easy, unlike the conventional way of tightening the screw while searching for the screw hole of the mounting bracket. is there.

Further, since the mounting bracket 5 is made of aluminum or the like, it can be integrally molded by die casting.
Excellent mass productivity and low manufacturing cost.

(Effects of the Invention) As described above, according to the present invention, since the mounting bracket has elasticity, it is attached to the ventilation port frame in advance, and the ventilation port frame can be attached to the duct simply by pushing it from the opening of the duct.
The work of installing the ventilation frame can be performed in a short time.

Also, when mounting on the duct, look for the screw hole of the mounting bracket,
Since there is no screwing work, the mounting work is extremely easy.

Furthermore, the mounting bracket can be integrally molded by die casting by using a material such as aluminum.
Mass productivity is excellent and manufacturing costs are low.
