Description

[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) This invention relates to a circular glass door that has been subjected to anti-glare treatment.

(Prior Art) A circular glass door (so-called round door) made of curved glass is provided at the entrance of a hotel, department store, etc. in order to emphasize the sense of luxury and decoration.

(Problem that the invention aims to solve) However, with such a circular glass door, light entering from the outside is reflected on the inner periphery, so it feels very glaring to people who approach the door. was giving.

Conventionally, door glass surfaces have been polished to prevent this glare.

However, door glass with the above-mentioned abrasion process loses its transparency, making it difficult to see inside and outside.
There was a problem that the sense of luxury and beauty was lost.

Structure of the Invention (Means for Solving the Problems) In order to solve the above problems, the present invention has arc-shaped rotating doors rotatably provided at a predetermined interval on the indoor side and the outdoor side. This circular glass door employs a structure in which at least the inner surface of the revolving door is provided with an anti-glare coating formed by applying paint.

(Function) By adopting the above configuration, the present invention does not lose the transparency of the door glass, so the visibility and aesthetics are not impaired, and the glare to the eyes is prevented so that the visual sense is not stimulated.

(Example) Hereinafter, examples 1 to 3 that embody the present invention will be described.
This will be explained according to the diagram.

As shown in FIG. 1, a circular glass door mounting frame 1 having a cylindrical shape of predetermined dimensions is fixed to the upper part of the entrance of a building. An opening (not shown) is provided along the outer periphery at the lower end of the outer periphery of the mounting frame 1, and a drive device (not shown) for moving the door is provided inside the mounting frame 1. .

Between the left and right sides of the mounting body 1 and the floor of the entrance,
A plate glass 3 having a curved cross section having a quarter-circle arc shape is fixed along the outer periphery of the mounting frame 1. On the inner circumferential side of the glass plate 3, four rotating doors 6, which are slightly smaller than the inner diameter and formed in an arc shape, are arranged so as to be rotatable at predetermined intervals so as to be located on the inside and outside of the room. ing.

A frame 4 is attached to the upper end of each rotating door 6, and is linked to the drive device (not shown) via the opening (not shown).

A frame 5 is attached to the lower part of the rotating door 6, and a guide protrusion (not shown) is provided so that the door slides along a circular groove (not shown) formed on the floor of the entrance. It's starting to move. In addition, there is a foot-operated switch 9 on the floor of the door entrance.
is provided, and when a person steps on it, the rotating door 6 is opened via a control device and a drive device (none of which are shown).
is starting to move.

Among the inner peripheral surfaces of the rotating door 6 and the door 3,
A belt-shaped anti-glare coating 7 is formed at a position ranging from a child's eye level to an adult's eye level.

The anti-glare coating 7 is formed by applying and drying a silicone resin coating 7a to a thickness of 10 to 20 mμ. The surface of the anti-glare treated film 7 has a light scattering effect due to the silicone particles, so that the glare caused by light reflection is weakened compared to an untreated surface.

The effects of the anti-glare glass embodied in the circular glass door as described above will be explained.

Part of the light incident from outside the door glass is scattered outward again by the anti-glare coating 7, but most of it is transmitted inside.

The transmitted light is scattered and weakened by the opposing rotating door 6 and the anti-glare coating 7 provided on the inner peripheral side of the glass 3.

Therefore, the visual field of the person inside the round door is not glared, and the outside can be seen from inside the round door, and the inside of the round door can be seen from the outside without impairing the sense of transparency.

Effects of the invention As detailed above, the circular glass door of this invention does not lose its transparency, so it is a invention that does not sacrifice luxury or beauty, and has an excellent anti-glare effect. be.
