Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ventilation structure for a sunroom or greenhouse.

There are two types of sunrooms and greenhouses: those with a detached structure and those with an architectural structure attached to the main building frame.
In either case, it is necessary to perform ventilation in order to adjust the indoor temperature by releasing heated air inside or introducing low-temperature air from outside.

For this reason, conventionally there is a type in which the entire roof is raised up, but in addition to the frame materials that make up the sunroom/roof, movable or fixed louvers or movable louvers are usually installed on the roof or side walls. We set up a satsushi,
In the case of a movable type, it was moved in a sliding or flip-up manner to communicate with the outside air.

However, apart from the fixed type that cannot adjust the amount of ventilation, a movable door or sash with an opening/closing function is provided in addition to the original fitting sash for daylighting, which increases the number of parts and makes it difficult to install on site. The work required a lot of effort and was expensive. Furthermore, it is difficult to provide a watertight seal between the movable part and the fixed part of the sash body, and furthermore, these movable parts detract from the aesthetic appearance of the sunroom or greenhouse.

Currently, it is common to use extruded aluminum alloy members for the frames of sunrooms and greenhouses manufactured, but current technology allows the production of extruded members with extremely complex cross-sectional shapes. The present invention focuses on the above-mentioned workability, and by configuring the ventilation device on the ridge member or side member of the sunroom/greenhouse, the movable ventilation racks and sashes used in the prior art are unnecessary, and the above-mentioned This eliminates the drawbacks of

The present invention will be described below with reference to an example of a sunroom attached to the frame of a main building.

As shown in Figures 1 and 2, the main building frame 1
In this case, mullions (vertical members) 2 are arranged in an inclined manner with a predetermined interval in consideration of drainage, and ridge members (horizontal members) 3 are arranged between them, and the ridge members 3 are fixed with screws, etc. It is fixed to the frame 1 to form the frame material of the sunroom roof. A channel-shaped glass plate receiving groove 4 is formed on the end face of the ridge member 3 facing toward the roof slope, and a glass plate 6 is supported via a tight material 5 such as rubber.

To describe the structure of the ridge member 3 in more detail with reference to FIG. Extending portion 1 extending diagonally outward and upward from the edge
Drainage gutter section 1 formed by 0 and vertical wall 8
1.

A small curved recess 12 in the middle of the horizontal wall 7 of the stepped portion 9
form. Reference numeral 13 denotes a lid member whose one edge is hinged to the ridge member over almost the entire length of the ridge member, and its cross section is formed into a T-shape by a horizontal piece 14 and a vertical piece 15. The inner end 16 of the horizontal piece 14 is formed to have a circular cross-section and is hinged to the recess 12, and the outer end 17 of the horizontal piece 14 is formed to have a C-shaped channel cross-section to which a tight material 18 is attached. The above-mentioned hinge-shaped lid member 13 has a tight material 18 at its outer end 17 which is connected to the above-mentioned extension part 1.
The inner surface of the vertical piece 15 is formed to be in close contact with the outer surface of the vertical wall 8 of the step portion 9 when the vertical piece 15 is brought into close contact with the outer end of the step portion 9 . It is convenient to attach an elastic tight material 19 made of sponge, cloth, etc. to the inner surface of the vertical piece 15.

A ventilation hole 20 is bored in the vertical wall 8 of the stepped portion 9, which communicates with the ridge member 3 in the lateral direction over a part or the entire length thereof.

Reference numeral 21 designates the above-mentioned opening/closing device for the lid member 13, which has a pivot point 22 pivoted to, for example, the mullion 2, and has a fork-shaped portion 23 at one end and an operating portion 24 at the other end. The aforementioned fork-shaped portion 23 clamps a pin 26 of an arm portion 25 fixed to the vertical piece 15 of the lid member. Arm part 25
may be passed through the ventilation hole 20, or the ventilation hole 2
A hole (not shown) may be provided in the vertical wall 8 at a location other than 0 and the hole may be passed through.

In operation, when the operating portion 24 of the opening/closing device 21 is manually operated and moved in the direction of the arrow 27, the lid member 13 springs up and occupies the position shown by the broken line.
The heated air inside the sunroom flows out through the ventilation hole 20. Even if you forget to close the lid member 23 and it rains, the lid member 13 acts as an eaves, so the rainwater does not enter the room through the ventilation hole 20, collects in the gutter 11, flows into the mullion 2, and drains outside. be done. Further, when the opening/closing device 21 is operated to the position shown by the solid line, the ventilation hole 20 is closed by the vertical piece 15 of the lid member 13, and furthermore, the outer end 17 of the horizontal piece 13 of the lid member 13 is closed by the vertical piece 15 of the lid member 13. The sunroom is completely sealed because it is hermetically sealed and double-closed.

Since the present invention is constructed as described above, it is easy to process and assemble in the factory, and the number of installation steps on site is reduced, leading to cost reductions.Furthermore, it is not only advantageous for rain protection, but also has a beautiful appearance. It has many advantages such as:

Claims (1)

[Scope of utility model registration request] A ventilation structure for a sunroom or greenhouse that is integrally formed with a ridge member made of a long extruded material,
A stepped portion 9 having a square cross section is formed in the ridge member, and a ventilation hole 20 is bored in the vertical wall 8 of the stepped portion to communicate the interior and exterior of the sunroom in the horizontal direction. A drainage gutter section 11 is formed by the vertical wall extending diagonally outward and upward from the edge and the extending section, and one edge of the vertical wall extends approximately the entire length of the ridge member. A lid member 13 hinged to the ridge member is provided over the ridge member,
Furthermore, an opening/closing device 21 having an arm portion 25 extending through the vertical wall and interlocking with the lid member is disposed on the indoor side below the step, and the lid member is opened by operating the opening/closing device. This ventilation structure for the roof of a sunroom or greenhouse is formed by communicating the indoor side of the sunroom with outside air through a ventilation hole 20 when the sunroom is closed, and sealingly covering the gutter part 11 with the lid member when the lid member is closed.
