Abstract

PURPOSE: To easily and firmly fit a sealing part to a louver in a louver roof or a structure simillar thereto. CONSTITUTION: This sealing protrusion 16 is constituted of a fitting member 17 having a nearly U-shaped section which is fittable to a flange 14 forming the vertical end of a louver 11 and a sealing member 18 formed of a flexible or elastic material to be connected to the fitting member 17. The sealing member 18 is constituted of a first leg 22 extending from a stem through beneath the basal part of the U-shaped section and a second leg 23 extending parallelly with the branch adjacent to the U-shaped section from the stem. When the adjacent louver closes together, the first leg 22 is pressed toward the fitting member 17 to rotate the sealing member 18 around the flexible stem 19 as a whole. Thereby, the second leg 23 is pressed on the flange 14 of the adjacent louver. In this way, a sturdy waterproof seal is formed between the vertical ends of the adjacent louvers.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to an improved seal mounted on a louver. The seal is intended to create a seal between the longitudinal ends of adjacent louvers to prevent water ingress when in the closed position.

[0002]

Prior Art Australian Patent Specification No. 606
In 74/86 and 33573/84, applicants described both adjustable louver roofs and machines for forming louvers by forming rollers. Both specifications have ends that are bent in such a way as to form a hollow louver with an oval cross section.
It describes a hollow louver formed from a sheet metal strip. Each longitudinal end is configured to engage an adjacent louver to provide wind and rain resistance when in the closed position. However, in the case where the rain is blown by the wind, there is a possibility that water may penetrate even with the wind and rain resistance given by the basic louver described in the above specification.

[0003]

SUMMARY OF THE INVENTION It is, therefore, an object of the present invention to provide a seal which can be easily and firmly attached to the louver of a louver roof or similar structure.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention provides
(A) A sealing protrusion comprising a mounting member attachable to the longitudinal end of the louver, and (b) a sealing member connected to the mounting member, the sealing member being formed of a flexible or elastic material. ..

Preferably, the mounting member has a substantially U-shaped cross section, and its size is such that it can be firmly mounted on the longitudinal end of the louver.

As the flexible or elastic material of the sealing member, for example, a suitable plastic material or rubber material is used.

It is desirable that the mounting member (a) be connected to the sealing member (b) by a stem.

The stem is preferably formed of a flexible or elastic material, which may be the same material as the sealing member.

[0009]

The sealing protrusion of the present invention can be easily and firmly attached to the louver by the attaching member attachable to the longitudinal end portion of the louver. A sealing member formed of a flexible or elastic material connected to the mounting member provides a strong waterproof seal when the adjacent louvers are closed together, and the longitudinal ends of the adjacent louvers. Formed between parts.

DESCRIPTION OF THE PREFERRED EMBODIMENT In the preferred embodiment, as described in the applicant's earlier patent specification, a louver roof 10 comprises a group of louvers 11 made up of a pair of rolls formed from sheet metal parts 12 of metal. To be done. The ends of the sheet metal 12 are bent together to form a flange 14. The flanges of adjacent louvers, when in the closed position,
They are interengaged to provide some wind and rain resistance.

However, rainwater is collected in the depressions 15 formed at the intersections between adjacent louvers, which water is then blown by wind through the gaps between the overlapping flanges of adjacent louvers.

Accordingly, as described in FIGS. 3, 4 and 6, the present invention provides a sealing protrusion comprising a mounting member 17 and a sealing member 18 interconnected by a flexible stem 19. Mounting member 17
Has a U-shaped cross section for fastening on the louver flange 14. Preferably, the mounting member 1
An inwardly facing lip 20 on one end of 7 is adapted to engage the end 21 of the bent louver to provide mounting safety. The mounting member 17 may be rigidly attached to the flange 14 or, alternatively,
It is moved in relation to the flange so that the sealing projection 16 can be moved automatically to the optimum sealing position. In this embodiment, the lip 20 prevents the sealing protrusion from coming off, and when the sealing protrusion is placed on the flange 14, the lip 20 does not have the end 21.
It is positioned so that it can be cleared at the last minute,
Therefore, the initial closure of the louver 11 causes the sealing protrusion 16 to move to the optimum sealing position.

Preferably, the stem 19 is connected to one branch of the U-shaped mounting member 17 in the vicinity of the connection between the branch and the base of the U-shaped cross section. The sealing member 18 includes a first leg portion 22 and a second leg portion 23. The first leg 22 extends from the stem below the base of the U-shaped cross section. Second leg 23
Extend from the stem parallel to adjacent branches of U-shaped cross section. When the adjacent louvers close together, the first leg 22 is urged towards the mounting member 17, thus rotating the sealing member 18 as a whole about the flexible stem 19, thereby causing the sealing member 18 to rotate. Flange 1 of louver with second leg 23 adjacent
Pushing against 4. Thus, a secure and waterproof seal is formed between the longitudinal ends of adjacent louvers.

Sealing member 18 is formed from a suitable flexible or resilient material such as plastic or rubber. Preferably, stem 19 is formed from a similar material. The attachment member 17 may be formed of the same or different materials. Preferably, mounting member 17 is formed of a relatively hard plastic, while stem 19 and sealing member 18 are formed of a softer and more flexible plastic or rubber. Alternatively, it is made to have a thin cross section so as to give the required flexibility.

In the alternative embodiment described in FIG. 5, the sealing member 18 is composed of only the first leg 22 and the second leg 23 is significantly reduced or even eliminated altogether.

FIG. 7 shows another embodiment of the present invention. The sealing member 18 comprises a longitudinal lip 24 mounted directly on the mounting member 17. The water 25 that collects in the depressions 15 at the intersections between adjacent louvers has been described by the lip 24 from the natural forces and in particular in terms of the preferred embodiment for ease of understanding, but various variations are contemplated by the invention. It should be understood that it can be done without departing from the principle of. Therefore, the invention should be understood to include within its scope all such variations.

For example, the mounting member 17 can be permanently attached to the louver, for example by adhesives, screws or bolts. The flexible stem 19 can be replaced with a pivot-like joint. The shape of the sealing member can be varied to fit different arrangements or overlapping flanges of the louver.

While the above has particular relevance to louver roofs, the sealing projections of the present invention can be used with any louver system.

[0019]

According to the present invention, a seal that can be easily and firmly attached to a louver of a louver roof or a similar structure can be obtained.
