Description

[Detailed explanation of the idea] 〔Technical field〕 This idea is related to daylight windows.

[Background technology]

In general lighting windows, a louver is attached to the ceiling opening below the skylight to prevent glare from sunlight on the indoor side. However, when cleaning a louver or a fluorescent light placed above the louver, it is necessary to remove the louver, but with conventional lighting windows, it is impossible or extremely difficult to remove the louver. Was.

[Purpose of invention]

The purpose of this invention is to provide a lighting window in which a semi-shading plate such as a louver can be easily attached and removed, and the semi-shading plate and fluorescent lamp can be easily cleaned.

[Disclosure of invention]

The lighting window of this invention has locking protrusions protruding from the lower part of the opposing inner peripheral surface of the opening frame attached to the ceiling opening below the skylight, and both ends of the semi-shading plate are fixed to the locking protrusions. The semi-shading plate can be installed within the opening frame, and by providing a hole for attaching and removing the semi-shading plate on one side of the inner circumferential surface facing the opening frame at a position above the locking protrusion, and inserting one end of the semi-shading plate into the hole for attaching and detaching the semi-shading plate. The other end can be pulled out below the opening frame. In this way, since we have provided a hole for attaching and removing the semi-shading plate, you can easily install the semi-shading plate by simply inserting one end of the semi-shading plate into the hole for attaching and removing the semi-shading plate, and pulling the other end of the semi-shading plate below the opening frame. can be removed to
You can also easily install a semi-shading plate by reversing the steps above.

An embodiment of this invention will be described with reference to FIGS. 1 to 4. That is, in this lighting window, as shown in FIGS. 1 to 3, an opening frame 3 is attached to a ceiling opening below a skylight 2 installed on a roof 1. This opening frame 3 has a locking protrusion 4 protruding along the lower part of its inner circumferential surface, and a lower outer flange 5 and an upper outer flange 6 protruding from the lower and upper parts of the outer circumferential surface, respectively. In addition, a fluorescent lamp 7 is provided on the upper part of the inner peripheral surface of the opening frame 3.
Install. Two louvers 8 are prepared, their peripheral edges are engaged with the locking protrusions 4, and the louvers 8 are placed in the right half and the left half of the opening frame 3, respectively. Between the louver 8 and the fluorescent lamp 7, a long hole 9 for attaching and detaching the louver is provided on the inner peripheral surface of the opening frame 3. This elongated hole 9 is configured such that by inserting one end 8a of the louver 8 into the elongated hole 9, the other end 8b of the louver 8 can be pulled out below the opening frame 3, as shown in FIG. In this case, the upper outer flange 6 of the opening frame 3 comes into contact with the inner wall surface 10 to form a louver insertion space 11 between the inner wall surface 10 and the outer peripheral surface 3a of the opening frame.

As a result of this configuration, one end 8a of the louver 8 is inserted into the elongated hole 9, and the other end 8b of the louver 8 is pulled out below the opening frame 3 and moved in the direction of arrow A, as shown by the imaginary line in FIG. The louver 8 can be removed from the opening frame 3 very easily by just using the above steps, and the louver 8 and the fluorescent lamp 7 can be easily cleaned. Further, the louver 8 can be attached to the opening frame 3 very easily by performing the operation opposite to the above. This is particularly useful in cases where the upper panel 12 is located above the opening frame 3 and the louver 8 cannot be lifted above the opening frame 3, as shown in FIG.

In addition, although the above embodiment describes the attachment and detachment of the louver 8, the same applies to the case where a semi-shading plate such as a semi-transparent plate is used instead of the louver 8.

[Effect of idea]

According to the lighting window of this invention, the semi-shading plate can be easily attached and removed, and the semi-shading plate and the fluorescent lamp can be easily cleaned.

Claims (1)

[Scope of utility model registration request] An opening frame that is attached to a ceiling opening below a skylight and has locking protrusions protruding from the lower part of the opposing inner circumferential surface, and a half that is attached to the opening frame with both ends hooked to the locking protrusions. A light shielding plate is formed on one side of the inner peripheral surface facing the opening frame at a position above the locking protrusion, and by inserting one end of the semi-shading plate, the other end of the semi-shading plate is moved below the opening frame. A lighting window equipped with a hole for attaching and detaching a semi-shading plate that can be pulled out.
