Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a ventilation hole frame that is installed on a ceiling, wall surface, etc. to form an air outlet or an air intake.

(Prior Art) Conventionally, there is a ventilation opening frame for a building that has detachable blades as disclosed in Japanese Utility Model Publication No. 51-40056.

In this case, the attachment/detachment mechanism for the blade is provided by penetrating a relatively small-diameter through hole in the length direction of the blade, protruding from one end of this through hole, and protruding from the open end of the other end. A mounting rod is elastically retractably protruded through a spring provided in the through hole, and one fastening member provided at the end of the ventilation hole frame is inserted into the insertion portion while the other is attached while contracting the spring. The rod was inserted, and then one mounting rod was inserted into the other fastening member to attach it.

(Problem to be solved by the invention) The thickness of the blades in the ventilation hole frame is relatively small, and it is not easy to make holes through the blade in the length direction of the blade. However, the problem was that it was not suitable for mass production.

(Means for Solving the Problems) In view of the above-mentioned points, the present invention provides a ventilation opening frame in which the blade attachment/detachment mechanism is excellent in workability and mass productivity. One of the blade mounting rods of a mounting member to which the end of the blade is attached is elastically movable, and the blade mounting rod fixed to the other mounting member and said one blade mounting rod are connected to each other at both ends of the blade. This is a vent frame that can be attached and detached by fitting and removing the mounting holes.

(Function) While holding the blade and fitting the mounting hole at one end into the movable blade mounting rod provided on one mounting member, the blade is elastically retracted, and the mounting hole at the other end is inserted into the blade mounting rod on the other mounting member. Once the blade is fitted and released, the movable blade attachment rod advances and both ends of the blade can be attached to the mounting member.

Further, in order to remove the blade, one end of the blade is moved to retract the movable blade mounting rod, and the mounting hole at the other end is separated from the blade mounting rod of another mounting member, so that the blade can be removed.

(Example) Embodiments of the present invention will be described with reference to the drawings.

The ventilation hole frame 1, which has a rectangular appearance, has a rectangular frame part 2 on the back side.
A mounting member 3 is fixed to the inside of one end, and a mounting member 4 is fixed to the inside of the other end.

As shown in FIG. 6, the mounting member 3 is fitted on both sides into fitting parts 5, 5 formed on the long sides 2a, 2a of the rectangular frame part 2, and is secured between the long sides 2a, 2a by a set screw 6. As shown in Figure 8, a mounting hole 7 is provided which is open at the front and at both ends, with a slit-shaped groove 7a at the top and a mounting groove 7b with a circular cross section at the bottom at the bottom. Screw holes 8 and 9 are provided from the rear surface to the mounting groove 7b.

Next, as shown in FIGS. 8, 9, and 10, an insertion member 10 is fixed in the mounting hole 7, and the upper part 10a of this insertion member 10 is inserted into the slit-like groove 7a, and the lower part Lateral cylindrical part 1
0b is inserted into the mounting groove 7b, screwed into the screw hole 8, and fixed by a set screw 12 passed through the through hole 11 at the bottom of the cylindrical part 10b, and the inner end of the cylindrical part 10b is attached. It is located midway to the left of the groove portion 7b, and the lower surface of the right end side of the upper portion 10a is located higher than the lower end of the slit-shaped groove portion 7a (see FIGS. 1 and 9).

Further, a piece 13 is fitted into the mounting hole 7, and the upper part 13a of this piece 13 is slidable in the lateral direction using the slit-shaped groove 7a as a guide, the lower cylindrical part 13b is used as a guide and the mounting groove 7b, and the lower part Cylindrical part 13b
The end of a set screw 14 screwed into the screw hole 9 is fitted into a long hole 13c extending through the bottom of the screw.

Furthermore, a female threaded portion 1 is attached to the lower cylindrical portion 13b of the piece 13.
3d, the end of the spring 15 inserted into the lower cylindrical part 13b is inserted into the cylindrical part 10b of the insertion member 10, and is locked with the set screw 12.
A rectangular cylindrical blade mounting rod 16 is screwed onto d and protrudes from the end surface of the mounting member 3.
The outer periphery of the mounting step portion 16a is formed as a fitting stepped portion 16a.

The mounting member 4 has the same shape and size as the mounting member 3, and is fixed to the inside of the other end of the rectangular frame portion 2 via a set screw 17, and another insertion member 19 is inserted into the mounting hole 18 of the mounting member 4. The insertion member 19 is fixed to the mounting member 4 through the set screw 20, and a rectangular columnar blade mounting rod 22 is screwed and fixed into the screw hole 21 of the insertion member 19. An attachment stepped portion 22a is formed on the outer periphery.

Mounting holes 24 and 25 are provided at both ends of the blade 23, and the mounting hole 24 at one end of the blade 23 is fitted into the mounting stepped portion 16a of one blade mounting rod 16.
While compressing the spring 15, remove the blade mounting rod 16 and the piece 1.
3 and retract to the left, and insert the mounting hole 25 at the other end into the mounting stepped portion 22 of the other blade mounting rod 22.
It is fitted and attached to a.

In the figure, 26 is a mounting bracket attached to the rectangular frame portion 2, and 27 is a mounting screw.

Since the present invention is configured as described above, when fixing it to a ceiling, wall surface, etc., after fitting and fixing the rectangular frame part 2 into the mounting frame (not shown), while holding the blade 23, one of the mounting holes 24 into one blade mounting rod 16 and move it slightly to the left, then fit the other mounting hole 25 into the other blade mounting rod 22, and when released, both ends of the blade 23 are attached to the mounting member 3 by the elasticity of the spring 15. , 4.

Also, while moving one of the blades 23 to the left and pushing one blade mounting rod 16, the other mounting hole 25 is separated from the other blade mounting rod 22, and one mounting hole 24 is moved to the left. It can be easily removed by removing it from the mounting rod 16.

In addition, in the case of a long ventilation hole frame, since a plurality of mounting members are provided so that a plurality of blades are arranged in series, a movable blade mounting rod structure is used for every other blade.

(Effects of the invention) In this invention, the blade mounting rod of one of the mounting members is elastically movable and the blade is provided with a mounting hole, so it can be attached and detached only by operating the blade, and the blade structure is extremely simple. Therefore, it is easy to work, has excellent workability and mass productivity, and has the effect of always stabilizing the attached state of the blade and increasing the rigidity of the blade.
