Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation duct or an air conditioning duct which is fixed to a wall or a ceiling or a floor by simply fitting it into a mating member. The present invention relates to a fitting-type article support device capable of fixing or supporting various articles to a plate-shaped mating member, such as a case in which a ventilation register is supported on a wall plate or a ceiling plate, and further, a lighting device is supported by the ceiling plate.

[0002]

2. Description of the Related Art Conventionally, as a means for supporting a flexible duct for ventilation or air conditioning on a wall plate or the like by fixing the end thereof, a connection pipe 51 with a nail-type flange as shown in FIG. 9 is known. I have. The flanged connection pipe 51 includes a tubular portion 52, a flange portion 53 provided on one side edge of the tubular portion 52, and a plurality of nail holes 54, 54, drilled in the flange portion 53. The cylindrical portion 52 is inserted into an opening B formed in a mounting plate A such as a wall plate, and a peg 55 into which a flange 53 abutting the mounting plate A is driven through a nail hole 54. The flexible duct F and the like are connected to a cylindrical body 52 which is fixed and protrudes to the other side of the mounting plate A. A connecting ring 61 with a snap ring type flange shown in FIG.
3 is formed, and a flanged tube 61 is attached to the mounting plate A by screwing a retaining ring 64 from the other side into the cylindrical portion 62 inserted into the opening B.
To be tightened.

[0003]

As described above, the conventional nailed connection pipe 51 with a flange has a disadvantage that it cannot be fixed when the mounting plate A is a gypsum board. Further, when a set screw is used in place of the peg 55, there is a problem that workability is poor because a screw receiver such as a nut cannot be fixed unless screwed from the opposite side of the mounting plate A.

[0004] Similarly, in the retaining ring type flanged connection pipe 61, the retaining ring 64 is attached to the mounting plate A during the construction of the plate A.
If the installation plate A and the connection pipe 61 are different from each other, there is a disadvantage that the work needs to be adjusted, and the external thread 63 is formed in the cylindrical portion 62. Therefore, when the retaining ring 64 is fastened to the cylindrical portion 62, the tightening operation is performed from both sides of the mounting plate so as not to rotate together, or the flange portion or the retaining ring 64 is fixed to the mounting plate A with a nail. And has the drawback that workability is extremely poor. In addition, the retaining ring 64 may be loosened with age.

[0005] The above-mentioned problems of the prior art are that a wall plate supports a clock, a ventilation register, a forehead, a decorative article,
When fixing or supporting various articles on a plate-shaped mating member, such as when a lighting device is supported by a floor plate, there is a similar problem due to the material of the plate-shaped mating member or locational restrictions.

The present invention has been made in view of the above-mentioned drawbacks of the prior art, and since various articles can be fixed or supported simply by being fitted into an opening from the near side of a plate-shaped mating member. An object of the present invention is to provide a fitting-type article support which has excellent resistance and can securely support various articles by firmly fitting to a plate-like mating member such as a gypsum board which does not work with nails. I do.

[0007]

According to a first aspect of the present invention, there is provided a cylindrical member which is inserted into an opening of a plate-shaped mating member from a distal end side. A flange portion forming plate provided on the rear end side of the cylindrical portion, and a plate-shaped mating member is sandwiched between the flange portion forming plate and provided on the outer peripheral surface of the cylindrical portion so as to be circumferentially separated. It consists of a plurality of elastic locking pieces.

Further, the flange forming plate may be formed with an opening communicating with the cylindrical portion.

Each of the elastic locking pieces gradually separates an inner edge from a fixed end on the base end side fixed to the cylindrical portion to a free end on the distal end side extending in the circumferential direction of the cylindrical portion from the flange portion. And the gap between the tip of the inner edge and the flange is set to be equal to or greater than the thickness of the plate-shaped mating member, and is larger than the cylindrical portion from the fixed end to the free end. It is good to be formed in a convex curved piece with a radius of curvature.

The elastic locking piece may be inclined such that an outer edge of the elastic locking piece is closer to the cylindrical portion than the inner edge.

Further, it is preferable that the elastic locking piece has a base end side separated from the flange in accordance with the thickness of the mounting plate and fixed to the cylindrical portion.

[0012]

Embodiments of the present invention will be described below in detail with reference to the drawings. 1 to 6 show a first embodiment of a flanged tube as an example of a fitting type article support tool. In the drawing, reference numeral 1 denotes a flanged pipe made of a metal material, and 2 denotes the flanged connection pipe 1 and has a tip at an opening B formed in a mounting plate A such as a wall plate, a ceiling plate, a floor plate, or the like, which is a plate-like mating member. 2A
Opening portion B into which the cylindrical portion 2 is inserted.
Is set so that there is a slight gap between it and the cylindrical portion 2. Numeral 3 denotes a flange forming plate integrally provided on the rear end 2B of the cylindrical portion 2. The flange forming plate 3 is such that a flange 3A on the outer peripheral side covers the entire edge of the opening B. An opening 3B communicating with the cylindrical portion 2 is formed in the center at the center.

Reference numerals 4, 4, and 4 denote three-piece elastic members provided on the outer peripheral surface 2C of the cylindrical portion 2 at intervals of 120 degrees in the circumferential direction in order to sandwich the mounting plate A with the flange portion 3A. A stop piece is shown. One end of each elastic locking piece 4 in the longitudinal direction is a wide fixed end 4A to be fixed to the cylindrical portion 2, and a distal end extending from the fixed end 4A in the circumferential direction of the cylindrical portion 2 is a free end 4B. while the outer edge 4C is substantially parallel to the flange portion 3A, with the inner edge 4D formed sandwiching the edge which is inclined so as to gradually away from the flange portion 3A, the tip 4D ₁ and the flange 3A of the inner edge 4D Is set to be equal to or greater than the thickness t of the mounting plate A. Thus, the elastic locking piece 4 has a tapered trapezoidal shape in a plane, is formed into a convex curved piece having a larger radius of curvature than the cylindrical portion 2 from the fixed end 4A to the free end 4B, and the outer edge 4C is more cylindrical than the inner edge 4D. It is formed in a slightly twisted shape so as to approach the part 2 side, and is formed of an elastic metal plate.

The present embodiment is configured as described above. For example, a case where the flanged connection pipe 1 is connected to the flexible duct F will be described with reference to FIGS. First, as shown in FIG. 3, put a hand in the opening B of the mounting plate A,
The flexible duct F located on the back side of the mounting plate A is pulled out to the near side of the mounting plate A. After fitting the flanged connection pipe 1 to the distal end side of the flexible duct F, the cylindrical portion 2 of the flanged connection pipe 1 is fitted to the opening B, and the flange is attached when the elastic locking piece 4 hits the rim. The connecting pipe 1 is pushed in while slowly rotating clockwise (rightward) in FIG.

Each of the elastic locking pieces 4 is formed in a convexly curved shape, and the outer edge 4C is slightly twisted forward and downward from the inner edge 4D. When the elastic locking piece 4 is pushed into the opening B while being slowly rotated, the elastic locking piece 4 is pushed down to the edge of the opening, so that the elastic locking piece 4 passes through the opening B as if the diameter is reduced. Then, the resilient locking pieces 4 and inclined inner edges 4D, since the distance T between the tip 4D ₁ and the flange 3A of the inner edge 4D is set to more than the thickness t of the mounting plate A, the free end 4 side is When penetrating through the back surface of the mounting plate A, the elastic force rises so as to gradually increase in diameter from the free end 4 side by the elastic force, and the elastic locking piece 4 sandwiches the mounting plate A between the flange portion 3A and the elastic locking piece. As a result, the flanged connection pipe 1 can be securely fitted to the mounting plate A. In addition, since each elastic locking piece 4 is constantly urged in the radially expanding direction, that is, in the rising direction by the elastic force, the mounting plate A is more strongly held between the elastic locking piece 4 and the flange 3A. Flanged connection pipe 1 fitted to mounting plate A
There is no loosening.

Next, FIG. 7 shows a flanged connection pipe 11 according to a second embodiment. Note that, in this embodiment and other embodiments described later, the same components as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. The features of the present embodiment include a fixed end 12A, a free end 12B, and an outer edge 12C.
Edge 1 of each elastic locking piece 12 composed of
2D is formed in a sawtooth shape. By forming such a serrated inner edge 12D on the elastic locking piece 12,
When the flanged connection pipe 11 is fitted to the mounting plate A, the serrated inner edge 12D firmly engages with the mounting plate A, so that the flanged connection pipe 11 rotates even when subjected to an external force in the rotational direction. Since it does not exist, it is possible to reliably prevent a situation of falling out of the opening B. Further, even when the thickness of the mounting plate A is variously varied, the serrated inner edge 12D is securely locked, so that the present invention is adaptable even when fitted to various mounting plates A having different thicknesses.

FIG. 8 shows a flanged connection pipe 21 according to a third embodiment.
No. 2 is that the fixed end 22A side is fixed to the cylindrical portion 2 with a distance from the flange portion 3A corresponding to the thickness t of the mounting plate A. With such a configuration, the mounting plate A is completely fitted between the flange portion 3A and the elastic locking piece 22, and even if the flanged connection pipe 21 receives an external force, the mounting plate A is opened from the opening B. It is possible to surely prevent the situation of falling off.

FIG. 9 shows a fitting-type wall-mounting support according to a fourth embodiment. The feature of the fitting-type wall-mounting support 31 is that the cylindrical portion 2 in the first embodiment is different from that of the first embodiment. Is formed by a disc having no opening, and a hook 33 for locking an article is provided substantially at the upper center of the flange formed body 32. According to the present embodiment, an article such as a timepiece or the like is shown by using the opening B by fitting the fit-type support 31 into the opening B formed in the mounting plate A such as a wall plate. Can be supported.

In each embodiment, the flanged connection pipe 1 is used.
(11, 21) Although the fitting-type wall hanging support 31 is formed of a metal material, it may be formed of a synthetic resin material. Further, although three elastic locking pieces 4 (12, 22) are provided on the cylindrical portion 2, at least two or more elastic locking pieces 4 may be provided, and the number thereof may be determined according to the diameter of the cylindrical portion. So,
The number of elastic locking pieces is not limited to the embodiment.

The inclination angle of the elastic locking pieces 4 (12, 22) with respect to the flange 3A can be appropriately determined in consideration of the thickness of the mounting plate A.

[0021]

The present invention has the following advantages because it is constructed as described in detail above. (1) Since all the work of connecting to the end of the pipe such as a duct and fitting and supporting the opening of the plate-shaped mating member can be performed from the near side of the plate-shaped mating member, the workability is excellent. I have. (2) Various articles such as pipes, clocks, foreheads, and lighting fixtures can be easily supported without using screws or the like by fitting a fitting type article support tool into an opening provided in the plate-shaped mating member. It can be used in a wide range of fields. (3) The configuration in which the plate-shaped mating member is sandwiched between the flange forming plate and the elastic locking piece eliminates the need for a fixing nail, so that it is ensured regardless of the material of the plate-shaped mating member. Can be fitted. (4) Since the elastic locking piece is sandwiched by the flange forming plate so as to bite into the plate-shaped mating member, the elastic locking piece does not loosen gradually like a snap ring type flanged connection pipe, and is excellent in reliability. (5) Since the elastic locking piece has an elastic force and the inner edge is an inclined edge, the elastic locking piece once holding the plate-shaped mating member between the elastic locking piece and the flange forming plate is more firmly held. And has excellent stability after fitting. (6) By setting the distance between the tip of the inner edge of the elastic locking piece and the flange forming plate to be equal to or greater than the plate thickness of the plate-shaped mating member, compatibility with plate-shaped mating members having different plate thicknesses is improved. Can have.
