Description

[Detailed description of the invention] This invention relates to a swing window that can be opened and closed inward.

The purpose of the swing window is to rotate the window glass 2' to scatter rainwater and maintain visibility, but it is difficult to open and close it because of the installation of a mechanism for rotating the window glass 2'. was the first person to file a patent application
No. 0514) Blowing compressed air between the outer end surface of the swing window 2 and the inner end surface of the bearing frame 1 that fits and holds the swing window 2,
In the case of a swing window in which the swing window 2 is rotated while floating in compressed air to minimize the swing resistance, it is necessary to ensure a supply path for the compressed air, and the swing window can be opened and closed to one side. Although it was difficult to do so, it is desirable to have a structure in which the swing window opens to one side for purposes such as cleaning window glass.

In this device, the inner surface of the bearing frame 1, for which the above-mentioned applicant previously applied for a patent, is a concave surface shaped like the letter ``■'', the outer end surface of the window frame on the outer periphery of the swing window 2 is made a protruding surface shaped like the letter ``■'', and the inner end surface of the bearing frame 1 is made a concave surface shaped like the letter ``■''. The ■-shaped protruding surface of the outer end of the swing window 2 is fitted into the ■-shaped concave surface of the swing window 2, and the swing window 2 is held in the bearing frame 1. A compressed air hole 11 is provided along the inner end surface of the bearing frame 1, and compressed air is Compressed air is blown out into the gap 13 between the bearing frame 1 and the swing window 2 from a large number of blow-off holes 12 provided at constant intervals between the holes 11 to keep the swing window 2 floating in the compressed air. The aim is to install a swing window 2, which has an extremely small turning resistance, into a window hole 7 provided in an outer wall 6 of a ship, etc., so that it can be opened and closed inward without interfering with the supply of compressed air. It is something that is important.

To explain the structure of this invention with reference to drawings, the swing window 2 has a structure in which a window frame whose outer end surface forms a ■-shaped protrusion is attached to the outer periphery of a disk window glass, and the swing window 2 can be freely rotated. The inner end surface of the bearing frame 1 to be secured is formed into a ■-shaped concave surface, compressed air holes 11 are provided inside along the inner end surface, and a large number of blow holes 12 are provided in the compressed air holes 11 at regular intervals. Frame 1
Compressed air is blown into the gap 13 between the ■-shaped concave surface on the inner end surface and the ■-shaped protruding surface on the outer end surface of the swing window 2 to keep the internal swing window 2 floating in the compressed air and reduce the swing resistance. Slightly tightening and turning is done in the same manner as in the swing window of the earlier invention, and instead of directly fixing the bearing frame 1 to the window hole 7 of the outer wall 6 of a ship, etc., the bearing frame 1 is Two left and right hinge arms 3 are attached to the upper end of the side surface with a constant interval maintained in the middle, and the bearing frame 1 is inserted through the pin hole through which the hinge pin 8 at the outer end of the two hinge arms 3 passes through the inside of the hinge arm 3. A communication hole 10 reaching an internal compressed air hole 11 is provided, and a circular window frame plate 5 is attached to the outer periphery of the inner side of a window hole 7 provided at a required position on the outer wall 6 of a ship, etc. Attach a hinge protrusion 4 with a width that fits between the two hinge arms 3, and
It is inserted between the hinge arms 3 of the book, and a common hinge pin 8 is passed through the horizontally penetrating pin holes provided at corresponding positions in the centers of the tips of the hinge arms 3 and the hinge protrusions 4, 2 is attached to a window hole 7 of a ship, etc., together with a bearing frame 1 that fits on the outer end thereof, by being hinged so that it can be opened and closed inward, and the hinge pin 8 has an air intake hole 9 with one end open and the other end sealed. A tubular body is used, and an outflow hole 9' opening on the side is provided at a position that coincides with the center of the two hinge arms 3 at both ends. Glue and fix it airtightly,
The position of the hinge protrusion 4 is rotatably mounted through the hinge pin 8, and the compressed air blown from the open end of the hinge pin 8 is connected to the communication hole 9 and the outflow hole 9' of the hinge pin 8 and the communication hole of the hinge arm 3. 10 and into the compressed air hole 11, so that the swing window 2 can be opened and closed inwardly around the hinge pin 8 together with the bearing frame 1 without damaging the compressed air blowing function.

The swing window of this invention, which can be opened and closed freely, has a swing window 2 whose outer end surface is a ■-shaped protruding surface, as described above, fitted and held in a bearing frame 1 whose inner end surface is a concave ■-shaped surface. Compressed air is supplied from a compressed air hole 11 provided along the inner end surface of the bearing frame 1 through a blowout hole 12 to a gap 13 between the bearing frame 1 and the swing window 2.
A window frame plate in which a swing window 2 is blown out to minimize the swing resistance of the swing window 2, and two left and right hinge arms 3 attached to a bearing frame 1 are attached to the inner surface of the outer periphery of a window hole 7 of an outer wall 6. 5 is rotatably hinged to the hinge protrusion 4 at the upper end with a hinge pin 8 of a hollow tubular body, and an outflow port 9 is inserted from the air intake hole 9 in the center of the hinge pin 8.
', the compressed air is sent to the compressed air hole 11 through the communication hole 10 provided through the inside of the hinge arm 3 and the bearing frame 1, without interfering with the turning function of the turning window 2. This has the effect that the swing window 2 together with the bearing frame 1 can be opened and closed inside the window hole 7 provided in the outer wall 6.
