PALTSTERN, transparent, can be illuminated without glare

* Purpose, aim, use, materials

The purpose of the new type of foldable, glare-free luminous / lighting fixture in the shape of a star is a combination (5 "> essential properties of previous models and improvements at the same time. (Fig. 1a, side view of an opened folding star - strong lines - ventilation flaps (33) inclined inwards).

The classic, glare-free, but rigid Advent and poinsettia stars have rays (-iols) connected by bars or frames and therefore have a visible support body.

The more portable, collapsible ( "gatherable", s. Lit.) have though an invisible support body in the form of ribs, but for the purpose of ventilation and cooling when electric lighting usually entirely or partially perforated (perforated) rays, or open i \ 5) points on the folded edges, which exert a disruptive glare effect due to the direct emission of light.

So the goal of the new development is:

A transparent, glare-free, electrically illuminable folded star with an invisible support body, which is formed by ribs (2o ^ pen (4, 4 ', 4 "in Fig. 2a, 2d). This results in a better effect and, through further improvements, a higher one Durability achieved.

Use as a light / lighting fixture for indoor and outdoor spaces - not only as an Advent and poinsettia star - but also for decorative purposes.

Suitable materials are transparent (white or colored) papers, light wood-free cardboard, plastics or other materials e.g. combinations with textiles.

The word 'spikes' is often used for 'rays'.

Since the folding principle can be assumed to be known (cf. L & 'inpions), itii shall follow only the essential differences de, or further improvements are shown.

2i The design of glare-free folds

(■ 5) General design options for the folding of the rays: In the central ray (1) of a folded star segment (Fig. 2a), the sides of the adjacent outer rays (6) are folded inwards. (Fig. 2b, top view of a folded star segment).

(-Ιο) Conversely: The central beam (1) folds outwards and the outer beams inward (Fig. 2c, 5,6).

The glare-free closing of the foldable beams is achieved by two different construction methods:

Due to the fold-like fold at the base of the

(15 "J sides or by penetrating the folded sides at their base. Scalike overlapping ^{1 means} that the folded sides (5, 6 in Fig. 2a and Fig. 2d) lay against each other like fish scales when the beams are opened and folded at the lower end (Fig. 2d, dashed line).

C2.0) 'Penetration' means that one of the two folded sides (5 or 6) penetrates a little through the fold of the opposite folded side, which is correspondingly wide open at the lower end. (Fig. 2d, dotted line).

For both types of construction, the folding sides (5, 6) are made about 4 % longer (25) than the beam sides (1, 2 in FIGS. 2a and 2d) attached to the ribs (4 or 4 ', 4 ").

These design options ensure that in each case one folded side is the opposite one on the base edge covered, which prevents direct light emission.

3. Glare-free ventilation flaps
C3o) -

The ventilation flaps in the form of regular or irregular geometric basic shapes (Fig. 3a, 3o - 36) are on two or three sides punched and traced at a shallow angle

inclined inside (i'ig. 1a and 2a). Acute-angled isosceles triangles (33) are preferably used because they also optically increase the shape of the star's rays. With this design of the ventilation flaps, a glare-free C5) exchange of air is achieved with permanent lighting (see also pip. 6a, 6b).

I ^{1 For} the use of the folded stars outdoors - weatherproof material provided - drainage openings for rain and condensation water can be arranged at the tips of the lower jets in the opposite way, for which the acute triangle (10) Bonders is suitable (Fig. 3b ),

4. Design of the pivot points

The usual adhesive folds (7 in Fig. 4 and Fig. 6a, 6b) to reinforce the outer base of a beam at the fulcrum (Fig. 4, 13) additional short adhesive folds (8) (Fig. 4 and 6b) f'isj attached. This prevents tearing and light leakage (The pivot point can also be seen in FIGS. 2a and 5).

The angle of the ribs (4 in Fig. 6d) or the rebate ribs (Fig. 6a-6c, 4 ', 4 ") should not be more than 45 ° at the pivot point (13) (Fig. 6b).

(20) A spreading lock (io in Fig. 2a and 5) at the ends of the pivoting flaps (9 in Fig. 5) - consisting, for. B. from eiuem textile tape or the like. - Limits the freedom of movement at the pivot point (13) to a minimum, whereby the tearing of the rays is prevented at this point.

(25) The measures mentioned in this section achieve a glare-free closure at the pivot point and significantly increased durability.

5. Swing flaps with handle

Swivel flaps (Fig. 5 number 9) - made of cardboard, light cardboard, (3O) Made of metal (sheet metal) or plastic - are actually reinforced ribs with a handle at the upper end (Fig. 5). They are beveled at the pivot point (13) at an angle of 45 - corresponding to the ribs (4) or rebate ribs (4 "in Fig. 6b).

The tip at the pivot point (13) can be shortened by a few millimeters will! .. A sealing fold is provided on each of the long sides (Fig. 5, 12; 11 = reinforcing folds).

The power supply for the electrical lighting should ideally (5) take place via a flat cable, although a different type of power supply is also possible. The hinged flaps (9) are closed immediately above the socket of the light bulb. For this purpose, clamps are attached to the upper part of the handle on both sides of the cable, whereby a good, light-tight seal is achieved ho) .

6. Design of the ribs for the folded stars

The ribs (4) are as centrally aligned strips for fastening (Gluing, stapling) the rays determined; the latter 'stand' each between two ribs. They are designed according to a Λι5 ^ polygon - preferably a regular hexagon. This is usually done in that the rays with the folds, which are provided on the immovable base edges are glued to the ribs, |

In the hexagon-based rib shape, three juxtaposed rays \ <2d \ between two ribs form a folded star segment (Fig. \ 2a). By multiplying the number of segments, folded stars with 15, 18, 21, 24 etc. rays can be produced.

In addition to the previously usual rib shape (can be seen in Fig. 6d), the glue seams on the beams can be designed so that

> Z5) when they are glued together (or stapled) they form a folded rib - an integrated rib - which makes the production of other ribs superfluous (material savings!) - (Fig. 6a, 6b - numbers 4 'and 4 ¹ '). In the drawing, FIG. 6a, an additional fold is provided on a fold rib 4 '. He serves the on

^{C5O 1} Most of the tensile stressed part of the folded terrarium. At the particularly stressed corners of the central rays (1), further strengthening can be achieved by stapling with stapling pliers (Fig. Bc, 14).

On ribs (4) between the folds (or fold ribs), for example, acute-angled triangles made of white or colored

Material (thicker drawing paper, lighter cardboard, etc.) can be arranged (Fig. 6d, 15). This results in additional flat jets, which visually appears particularly advantageous in Faltsternen with a lower number of beams, for example, 15 of illumination inside (^ ended beams and between the central rays or 5 flat jets (15) are illuminated indirectly (Fig. 6d, without the Side triangles).

7. Raising and shortening of the external rays

In the construction of the folded stars, the outer rays C-jtA of a folded star segment ground purely geometrically at right angles (perpendicular) placed on the associated rib parts with the same ray height, then the unfolded star creates an optically unattractive Concentration of the rays in the side view (see Fig. 1a, thin lines).

('JS) This error is corrected by raising the outer beams by about 7 ° and shortening these beams by about 10 % compared to the central beams (Fig. 1b). In this way, a harmonious, pleasing shape of the entire folded star is created (Fig. 1a, strong lines).
