DE467132C - Luminous switch for electrical systems, billboards or the like with a covering that also shines in the dark - Google Patents

Description

The invention relates to a luminous switch for electrical, systems, z. B. for light and bell systems on billboards o. The like., With one in the dark luminous cover. What is new is that this glow-in-the-dark cover consists of two interlocking, im pliable capsules made of viscose, acetyl cellulose and applied in moist conditions ίο or similar substances that match the shape of the item to be covered adjust automatically when it dries out, and of which the inner capsule is opaque and with a binder coat and then a coat of luminescent paint as well on the latter, in turn, is provided with a further binder spread in such a way that the luminescent paint is embedded between the binder layers, while the other outer capsule is colorless and completely transparent, and is drawn over the first. Such capsules make it possible to switch light, bell or similar switching devices to be identified in the simplest way, even in the dark, with the special Advantage that the capsules of the luminous material provide excellent protection against damaging influences and thus the highest Grant durability.

Without falling from the scope of the 'invention, such capsules can also be used as Coating for license plates, boards or the like. Can be used.

The usability can be up to 10 years depending on the luminous materials used be effected.

The object of the present invention is shown on the accompanying drawing.

Fig. Ι shows the on a larger scale Toggle for a light switch on which a double capsule with an intermediate layer of leukjht color is postponed according to the invention, on the left in section and on the right in view.

Fig. 2 shows a horizontal section along line AB in Fig. 1.

With the double capsule according to Fig; 1 and 2, the inner capsule is formed in that a coating b of transparent binder is applied to an opaque white layer and a layer c of luminous paint is applied to this coating. The latter is covered with a spread d of transparent binder.

The layers a, b mentioned form ¹ the inner capsule for the luminous color layer c; On top of the cover layer d of the latter, a completely transparent layer is applied to form the second outer capsule.

The double capsule formed, with the luminous color layer c enclosed by it, is immersed in a binding agent to form a sealing bead on its lower edge so that the bead can achieve a seal that prevents liquid from penetrating into the luminous color layer enclosed by both capsules, and which is necessary because the capsules must be stored ^{in formaldehyde solution before use 1} , for example before they are pushed onto the toggle /. Before the double capsule is pushed onto the toggle, the sealing bead is lifted off with a knife. ·

Claims (1)

Claim: Luminous switch for electrical systems, billboards or the like with a also glow in the dark cover, characterized in that this glow in the dark cover consists of two interlocking, pliable capsules made of viscose, acetyloellulose or similar when applied in a moist state Substances that follow the shape of the item to be covered when it dries up adapt automatically, and of which the inner capsule is opaque and with a binding agent atif coating and go then provided with a coat of luminous paint and on the latter in turn with a further coating of binding agent is that the luminous color between. is embedded in the binder layers, while the other outer capsule is colorless and completely transparent and is pulled over the first.
