CH711491A2 - Folded lantern with automatic system for simultaneous deployment and lighting. - Google Patents

Abstract

The folded lantern with a deployment and simultaneous lighting system is equipped with two hooking points (3) for fixing the elastic (1) to the interior walls of said lantern. When the lantern kept folded is projected into space, the elastic relaxes and allows the walls of the lantern to unfold. During said movement the tongue (9) fixed inside the wall moves with it and acts as a switch by closing the electrical circuit, the energy then contained in the battery, driven by the connection system, allows the activation of the LED (7). Thanks to the relaxation of the elastic, the lantern opens and illuminates simultaneously. The use of the aforementioned lantern is to ensure through a clever and fun process an autonomous lighting, warm and practical, which lends itself to mobility.

Description

Object and / or technical field:

The invention relates to a folding lantern, which lights up and unfolds in a simultaneous movement, when said lantern is projected into space.

Description of the invention

The lantern in its original form has existed for millennia, often portable, consisting of a box or envelope with transparent or translucent walls, inside which is placed a light source, it usually contains a candle , or for the most recent model, an external electric light source. Traditionally, when the light source is of electrical origin, a fixed wiring system is required, which attaches said light source to an external power source, and restricts its mobility in space. Some lanterns without cables also exist, but operate with an energy accumulation system "accu", mostly bulky and expensive and they are not collapsible. There are also flashlights that are portable and provide a frontal light. They are used to troubleshoot or advance in dark areas.

Although the list above-mentioned is by no means exhaustive, it evokes most of the inventions that the technique produced to give us the means to have light when we wish. These have disadvantages because of multiple factors. The traditional lamps are heavy and bulky, their volumes are fixed, they are not designed to guarantee a mobile lighting, the light they broadcast is confined to a fixed area. To move them, you have to turn them off.

In addition, flashlights do not diffuse a mood light. They do not have a fine and modern design, they are not foldable nor decorative. For them to work you have to manually operate a switch and there is no playful dimension in their uses. The candle traditionally contained in the lantern can be moved while illuminating, but it is consumed and disappears very quickly; it can also generate smoke and fire hazards. Finally, to illuminate, the candle must remain straight, if it is reversed, it goes out. The candle can not guarantee lighting in all positions.

It is precisely the object of the present invention to provide a solution that overcomes the aforementioned drawbacks.

The object of the present invention is to develop an autonomous and playful lighting system that can be used in large gatherings of humans as well as in intimacy, outdoors and indoors by ensuring lighting warm and soft atmosphere, while being mobile and easy to use.

When the lantern is not lit, it is folded and is in flattened form by keeping the elastic under tension. It therefore takes very little space to store and store. Thanks to its elastic system it deploys in a clever way and allows simultaneous lighting, without the user needing to press a switch. The simple projection of the lantern into the space activates the lighting mechanism while allowing the shape of said lantern to deploy in all its wingspan.

The volume can important said lantern once deployed and its low weight, allows the user to keep it in the palm of the hand, or to launch it to another user, using it as a balloon, this which gives the lantern an undeniable playfulness, and an ergonomic dimension. Thanks to its multi-face geometrical shape, it can rest on any type of support while keeping visually the same aspect and guaranteeing the same quality of lighting in any position.

The features described in claim 1 solve the technical problem.

[0010] Profitable developments follow from claim 1.

The advantage of the invention lies in the fact that it deploys and illuminates simultaneously to materialize a lantern with soft and warm lighting used in any type of context, both outside and inside without having to connect the lantern to an external power source, which gives it a unique autonomy and flexibility of use. In addition, when the lantern is folded, it has the advantage of being able to be stored and moved easily.

[0012] Adapted to the morphology of the hand, it can be launched in the space of a user to another, which ensures a high mobility and a certain playfulness.

Claims (1)

1. Lantern with a simultaneous deployment and lighting system, characterized by its self-adhesive acetate walls covered with crumpled Tyvek paper, and a luminous device comprising an elastic band (Figure 1, item 5). ), a plastic tab as a switch (figure 2, figure 1) and an electric circuit (figure 2) equipped with a metal contact tab (figure 2 figure 2), a power LED (fig 2, figure 3), a 3 V lithium battery (figure 2, figure 4), a support of the electrical circuit (figure 2, figure 5), a connection system: black phase cables (figure 2, figure 6), red phase cable (figure 2, figure 7). Inside the Lantern, two points of attachment serve to fix the elastic to the walls of the Lantern. When the folded Lantern is projected into space, the elastic relaxes and allows the walls of the Lantern to unfold. During said movement the tongue fixed inside the wall moves with it and acts as a switch by closing the electrical circuit (closed circuit), the energy then contained in the battery, driven by the connection system, allows activation of the LED. Thanks to the relaxation of the elastic, the Lantern opens and illuminates simultaneously. Conversely, when the Lantern is held folded, the elastic stretches and prevents the walls of the Lantern from being deployed by maintaining the tab serving as a switch in a position that interrupts the electrical circuit (open circuit).
