AI Technical Summary
Existing light shaft covers are prone to connection failures due to the use of metal spring clips and threaded bolts, which can break, leading to potential rainwater penetration and damage to the facade.
A plug-in light shaft cover made of clear acrylic glass with a thickness of 4 mm, secured by metal spring clips with screw-nut connections, and connectors with threaded bolts, washers, and nuts, combined with a PVC hose seal to prevent rainwater ingress, and optional wind protection using a chain connection and wire mesh or gauze dirt cover.
The solution effectively prevents rainwater penetration, ensuring the integrity of the light shaft and facade by providing a durable and weatherproof cover system.

Abstract
Description
[0001] In [ Fig. 1] shows the cross-section through a built-in light shaft with cover. The facade of the house [ Fig. 1 (1)], the underlying soil [ Fig. 1 (2)] and the installed light shaft [ Fig. 1 (3)]. Furthermore, the light well cover [ Fig. 1 (4)], the clamping pieces [ Fig. 1 (5)] and the connectors [ Fig. 1 (6)] visualized.
[0002] The [ Fig. 2] shows the top view of the light well cover. Here, the connecting rod [ Fig. 2 (7)] and the grating of the light shaft [ Fig. 2 (8)].
[0003] The [ Fig. 3] visualizes the side detail view of the clamping pieces [ Fig. 1 and Fig. 3 (5)] and the connector [ Fig. 1 and Fig. 3 (6)]. Here, the interaction of the two connecting elements is shown in detail.
[0004] The [ Fig. 4] shows the top view of the connecting elements (clamps and connectors). Here it can be seen that on the connecting rod [ Fig. 2, Fig. 3 and Fig. 4 (7)] the connecting elements [ Fig. 1, Fig. 3 and Fig. 4 (5 and 6)] are installed offset.
[0005] The light well cover is cut to the size of the light well. The cover should be made of a clear acrylic sheet with a thickness of 4 mm. Depending on the size of the light well cover, several clamping pieces [ Fig. 1, Fig. 3 and Fig. 4 (5)]. These clamps consist of metal spring clips with a screw-nut connection and are used to fix the cover to the steel rod [ Fig. 1, Fig. 3 and Fig. 4 (7)]. This connection can be released at any time.
[0006] Two connectors [ Fig. 1, Fig. 3 and Fig. 4 (6)]. These connectors consist of a threaded bolt with an eyelet, washers, and nuts. These connectors are connected to a metal connecting rod [ Fig. 1, Fig. 3 and Fig. 4 (7)] loosely connected. The thickness of the rod corresponds to the inner diameter of the eyelet.
[0007] The light well cover is larger than the grating to achieve a slope. A cut PVC hose is recommended as a façade finish. This seals the system against rainwater and prevents façade damage. My hose cutter (Utility Model 20 2023 001 862 dated February 5, 2024) is suitable for creating this seal.
[0008] A wind protection device can also be installed. This is achieved by attaching a chain link between an additional threaded eyelet connection and the grating. A dirt cover made of wire mesh or gauze can be integrated.
[0009] Like conventional systems, the plug-in light well cover prevents rainwater from penetrating the light well and thus relieves the burden on its drainage.
Claims
[1] The plug-in light shaft cover consists of a clear acrylic glass plate, a connector consisting of a threaded bolt-screw-nut combination, a clamping piece consisting of a steel spring clip-screw-nut combination and an iron rod. [2] The cover according to claim 1 is characterized in that it is firmly connected to the grating of the light shaft by means of the clamp connection, but can be removed again at any time and without tools. [3] The cover according to claim 1 is characterized in that the entire construction is firmly mounted but not directly connected to the house facade.
