Description

[Detailed description of the invention] <Industrial application field> This invention consists of a cylindrical member that fits into a ventilation hole formed in the wall of a building, and a face member that is connected to this cylindrical member. In particular, the present invention relates to a vent cap in which the face member has a rectangular shape with a width larger than the diameter of the cylindrical member.

<Prior art> Depending on the condition of the wall surface on which the vent cap is attached, it may be necessary to install the vent cap with the center line of the ventilation hole (i.e., the center line of the cylindrical member) offset from the center line of the face member. . In other words, there may be cases where there is something like a wattmeter near the ventilation hole, and the wattmeter and face member will interfere with each other, or it may be necessary to match the tiles on the wall with the face member in order not to impair the design. This may be the case when there is a vent cap, or when it is necessary to align multiple vent caps.

In order to meet these demands, we have developed a vent cap that can be easily installed on site by shifting the center line of the cylindrical member and the center line of the face member.
The present applicant previously filed Utility Application No. 62-63497
-172849), Utility Application No. 62-63498 (Utility Application No. 17284-
41039) and Utility Application No. 63-67578 (Utility Application No. 1983-
172634).

However, all of these methods are related to a type having a circular or square face member, and are not necessarily satisfactory for a type having a square face member, especially a horizontally long rectangular face member. do not have.

In other words, in the case of a type with a horizontally long rectangular face member, the size of the face member must be a multiple of the tile so that it fits properly into the tile joint. Since the relationship between

In addition, in the case of this type, the lateral ratio is large compared to the size of the cylindrical member, that is, the ventilation hole, which also requires a relatively large "shift".

However, in the conventional example, it is difficult to ensure such a large "shift".

On the other hand, structures that ensure a relatively large "shift" in the lateral direction are known, for example, as shown in FIGS. 2 and 3.
(Refer to Utility Model No. 52-11806).

This conventional vent cap 1 is made up of a cylindrical member 2 and a face member 3, and is attached to a ventilation hole in a wall of a building by fitting the cylindrical member 2 together.

The cylindrical member 2 has a cylindrical shape, and a base plate 5 is attached to the periphery of the distal end thereof in the form of a flange. The height of the base plate 5 is approximately the same as the height of the face member 3, but its width is narrower than the width of the face member 3.

The face member 3 has a rectangular shape and is made up of a main body member 6 in the shape of a flat rectangular tube and a cover member 7 with a rattle attached thereto. Connecting grooves 8, 8 are provided. It should be noted that a hood member 9 may be attached to the face member 3, if necessary, or a net, punched metal, or the like may be used for the cover member 7 instead of a louver.

The cylindrical member 2 and the face member 3 are connected by sliding and fitting the upper and lower ends of the base plate 5 into a pair of upper and lower connection grooves 8, 8.

That is, the cylindrical member 2 and the face member 3 are relative to each other in the width direction of the face member 3 (direction of arrow X in FIG. 3) due to the sliding contact and fitting structure with the connection grooves 8, 8 of the base plate 5. They are connected so that they can slide, that is, so that the center line 2a of the cylindrical member 2 and the center line 3a of the face member 3 are shifted from each other.

Furthermore, a plurality of screw holes 9, 9... are formed at appropriate intervals on the outer side wall 8o of the connecting groove 8,
Once the on-site alignment has been completed, screw the screw into the appropriate screw hole 9 and attach it to the other side wall 8 of the connection groove 8.
By pressing the base plate 5 on the cylindrical member 2
Both the face member 3 and the face member 3 can be kept in a fixed state.

In this way, this conventional structure allows a relatively large "shift" in the lateral direction.

However, this conventional structure has the disadvantage that it cannot be "shifted" in the vertical direction, and cannot accommodate adjustment in the vertical direction, which particularly requires high consistency with the joints of the tiles.

<Problems to be solved by the invention> Therefore, in this invention, the "shift" between the center line of the cylindrical member and the center line of the face member, which is required for a type having a square-shaped face member, especially a horizontally long rectangular face member, is solved. The aim is to provide a vent cap that can be easily applied on-site.

<Means for solving the problem> Specifically, the vent consists of a cylindrical member that fits into a ventilation hole formed in the wall of a building, and a square face member whose width is larger than the diameter of this cylindrical member. A cap, in which an intermediate member is interposed between the cylindrical member and the face member, the cylindrical member is connected to the intermediate member so as to be slidable in one direction, and the intermediate member is connected to the cylindrical member. To provide a vent cap, which is connected to a face member so as to be slidable in a direction crossing the sliding direction.

<Function> According to this vent cap, the combination of the sliding of the cylindrical member relative to the intermediate member and the sliding of the intermediate member relative to the face member allows the center line of the cylindrical member to be aligned with the center line of the face member in both the horizontal and vertical directions. Large "shifts" can be easily applied on site.

<Example> Hereinafter, an example of this invention will be described based on the drawings. In the following description, common reference numerals are used for parts common to those of the conventional example described above, and overlapping descriptions are omitted as appropriate.

This vent cap 30 is made up of a cylindrical member 2 and a face member 3, similar to the conventional vent cap 1 described above.

A base plate 5 is attached to the periphery of the tip of the cylindrical member 2 in the form of a flange.
Its height is lower than the height of the face member 3, and its width is narrower than the width of the face member 3.

Although the face member 3 is shown in a simplified manner in FIG. 1, its structure is similar to that shown in FIGS.
Cover member 7 with a rattle, similar to the conventional example shown in the figure.
(not shown) is attached to the main body member 6, and the main body member 6 has a side wall 8 on its base end side.
A pair of upper and lower connecting grooves 8 formed by the side wall 8o and the connecting groove 8o are provided. Further, if necessary, a hood member 9 as shown in FIG. 2 may be attached to the face member 3, or a net, punching metal, etc. may be used for the cover member 7 instead of a louver. .

The cylindrical member 2 and the face member 3 are connected via the intermediate member 32 so that the cylindrical member 2 and the face member 3 can relatively slide in both the height direction and the width direction of the face member 3. has been done.

Specifically, the auxiliary connection groove 3 is made into a pair on both the left and right sides.
1 and 31 are interposed between the cylindrical member 2 and the face member 3,
The cylindrical member 2 is inserted into the auxiliary connection grooves 31, 31 of the intermediate member 32.
Both left and right ends of the base plate 5 are slidably contacted and fitted, and both upper and lower ends of the intermediate member 32 are slidably contacted and fitted into the connecting grooves 8, 8 of the face member 3.

In other words, this vent cap 30 can slide relative to the face member 3 in the width direction (direction of arrow Y in FIG. 1) due to its sliding contact and fitting structure with the connecting grooves 8, 8 of the intermediate member 32. As well as,
Due to the sliding contact/fitting structure of the base plate 5 to the auxiliary connection grooves 31, 31 of the intermediate member 32,
It is possible to slide relative to each other in the height direction (arrow X direction in FIG. 1), and by sliding in each direction, the center line of the cylindrical member 2 and the center line of the face member 3 It is designed to shift the distance between the two.

Although not shown in FIG. 1, a plurality of screw holes 9, 9, . . . as seen in the conventional example shown in FIG. When the on-site alignment is completed, screw the screw into the appropriate screw hole 9 and connect the connecting groove 8.
Both the cylindrical member 2 and the face member 3 may be fixed by pressing the base plate 5 against the other side wall 8i.

Further, although not shown, it is convenient to attach a scale to the front side of the side wall 8o and to shift the position based on this scale.

<Effects of the invention> As explained above, in the vent cap according to this invention, the cylindrical member and the face member are connected via the intermediate member, and the cylindrical member and the face member are connected in the width direction and height direction of the face member. is designed to be relatively slidable, so by sliding the face member in each direction with respect to the cylindrical member, it is easy to make a large " It is possible to give a "shift".

Therefore, this vent cap can be constructed in a more suitable manner by easily adapting it to the relationship with the items surrounding the ventilation hole and the pattern of the tiles on the wall.
In particular, it has a great effect in that it can meet the demand for accurate matching with the tile pattern, which is required due to the rectangular shape.
