Abstract

A stand (10) for a printed product comprises a rigid, foldable plate (12) of a substantially rectangular form. The plate (12) has a first weakening line (18) extending over the whole length of one side (16) to form a strip (20) that can be folded back and acts as a supporting surface for the printed product (14) when the stand (10) is erected. The plate (12) can also be folded in half perpendicularly to the strip (20) along a second weakening line (24). A retaining flap (58) is preferably designed for each folded-back flap (26).

Description

Stands for a printed matter

The invention relates to a stand for a printed product, which consists of a rigid, foldable plate of substantially rectangular shape.

Stands for printed matter, for example for sheet music, books, magazines, brochures, brochures, but also for lecture notes, are usually made of metal and / or wood and are therefore of a solid, heavy construction. This is useful for an orchestral formation during a concert, fixed speakers or stationary exhibitions, but not for temporary use while traveling, at work, or traveling exhibitions with little transport capacity.

In particular, it is unreasonable for a musician to carry in his hand luggage a heavy, even folded, bulky music stand, which he can easily set up and use in the hotel.

From GB, A 1561778 a music stand consisting of two plates made of a cheap and light material is known, which are connected to one another like a hinge. These two plates can be set up in the form of an inverted V and secured with two cords. Hinged on the long side of a plate there are two hinge-like strips that extend over their entire length and, when the stand is spread apart, form a second inverted V, which forms a support surface for the sheet music. Although this embodiment is a welcome simplification compared to massive, bulky music stands when traveling, the design is still complicated in that Handling complex and not optimally space-saving.

Another stand, particularly intended for exhibitions, is disclosed in GB, A 1503451. An exhibition stand is formed from a plate of complicated circumferential shape provided with numerous folding lines and several insertion slots, which forms an inclined support surface and below it a support surface for the printed product to be exhibited. The complicated shape requires a lot of routine and skill to fold and is prone to damage due to the complicated outer contours.

The inventor has set itself the task of creating a stand of the type mentioned, which is easier to manufacture, transport and set up with sufficient stability and low price.

The object is achieved according to the invention in that the plate comprises a first line of weakness extending over the entire length of one side for a bendable strip, which serves as a support surface for the printed product when the stand is set up, and in that the plate is longitudinally perpendicular to the strip along a second line of weakness is foldable. Special and further developing embodiments of the invention are the subject of dependent patent claims.

The basic embodiment of the invention preferably has the standardized A3 format and can be folded longitudinally to the A4 format thanks to a line of weakness. Such a stand has a minimal space requirement and has space in every music folder. The strip used as a support surface is secured when the stand is folded, it cannot be folded over. With a flat surface, this stand can be leaned against any stable object at any angle and the printed product can be placed on it. The greater the weight of the printed product, the more the angled stiffener is pressed onto the base and the frictional resistance, with others Words increased security against unwanted sliding away. For example, a traveling musician is offered a music stand that is cheap, light and easy to transport with the smallest space requirement.

The stand according to the invention preferably has at least one pivotable tab on each half of the plate, which in the unfolded position of the stand can give the plate, which is expediently slightly inclined backwards, an automatic hold. In practice, the pivotable tabs are symmetrical with respect to the longitudinal center line of weakness of the plate. This ensures that the unfolded plate of the stand is evenly supported on a flat surface.

The contact surface for the printed product is generally only slightly inclined with respect to the vertical, for example 10 to 20 °, in particular approximately 15 °. This angle of inclination is determined in the free-standing variant of the invention by the tabs which can be pivoted into an approximately vertical position and which are therefore punched out in a precisely predetermined shape.

With or without pivotable flaps, the plate according to the invention preferably consists of cardboard, corrugated cardboard with two cover layers, plastic or a corresponding rigid, but foldable composite material. Because of its low weight, corrugated cardboard is particularly suitable for travel purposes.

The preferably 1 to 2 mm thick plate can in principle have any surface format, but for practical reasons the plates are essentially rectangular or square. Of course, the corners can be rounded or similar, functionally ineffective measures can be taken. As already mentioned, the A3 format is particularly suitable for practical reasons. The pivotable strip is usually 2 to 4 cm, in particular about 3 cm wide. The lines of weakness can be designed as a cut, for example with a depth of cut of 60 to 90% with respect to the thickness of the plate. Furthermore, the weakening line can be formed by material removed in a wedge shape on at least one side of the plate, 10 to 40% of the plate thickness remaining in the region of the weakening line, for example. The wedge-shaped material removal takes place in particular in the case of solidly designed plates. Simple cuts are preferred, in particular, for sheets made of corrugated cardboard or foamed plastic.

Depending on the intended price range of the stand, it can also be of better quality and more user-friendly:

- A board made of cardboard or corrugated cardboard can be coated on at least one side with a tear and wear-resistant plastic film, which preferably also gives it increased sliding resistance. For example, polyethylene (PE), polypropylene (PP) or polyester films (PE) are suitable.

- Improvements can also be achieved in a targeted manner, for example by gluing a tear and wear-resistant plastic strip in the area of the longitudinal center line of weakness. Of course, a strip can also be glued to the other lines of weakness.

The slip resistance of the bendable strip with respect to the base and / or the printed product can also be increased by gluing non-slip foils on one or both sides over the entire length or over certain areas or by spraying on corresponding material.

- The slip resistance on both sides of the strip can also be increased by embossing one or both sides, for example in the form of Ribs, a corrugation, knobs or the like, also combined with the measures mentioned above.

An embossing of the strip should, however, only lead to slight increases, so that the small space requirement of the longitudinally folded stand is not increased.

The slipping of the printed product placed on a stand, in particular when turning notes, can also or additionally be reduced by increasing the angled strip on the free long side by a foldable edge or an underlying object, such as a pencil or rubber wedge. However, this measure only makes sense if there is insufficient sliding resistance against the surface.

Another advantage of the stand according to the invention is that it can be used as an advertising medium and is therefore suitable as a giveaway. In the same work step as applying weakening lines and punching out swiveling tabs and any other measures, a partial or full-surface advertising print can be applied at least on one side.

With a view to personal needs and for cost optimization, the stands according to the invention can also be delivered as simple or more varied sets. A simple plate with lines of weakness for the strip and for longitudinal folding, but also with punched-out flaps, can be added, for example, with self-adhesive strips to improve the tear resistance and / or the sliding resistance. More diverse sets can also have self-adhesive foils to strengthen lines of weakness.

In summary, it is again stated that the inventive Stands are widely used, for example, as travel stands for musicians, and as supports for books, magazines, brochures and brochures. Of particular note is the simple, light and space-saving design. Furthermore, a stand according to the invention in an unfolded A3 format is also outstandingly suitable as a stable base on a conventional, also foldable music stand of much smaller format because of its size and its anti-slip support surface, so that printed single sheets are also securely placed. Finally, a stand according to the invention can simultaneously be used as a protective folder for printed single sheets.

The invention is explained in more detail with reference to exemplary embodiments shown in the drawing, which are also the subject of dependent claims. They show schematically:

1 is a plan view of a plate with lines of weakness,

2 shows a plate according to FIG. 1 with additional punched-out tabs,

3 is a plan view of the longitudinally folded plate,

4 shows a side view of a stand which can be set up automatically, FIG. 5 shows a partial section of a plate in the region of a weakening line,

6 shows a variant according to FIG. 5 with a wedge-shaped recess on one side,

7 shows a variant according to FIG. 5 with a wedge-shaped recess on both sides, FIG. 8 shows a partial top view of a bendable strip with various measures for anti-slip protection.

- Fig. 9 is a plan view of a variant according to Fig. 2 with latches, and

10 is a perspective view of a latched tab according to FIG. 9. An approximately 1.5 mm thick plate made of corrugated cardboard of A3 format shown in FIG. 1 is used to produce a stand 10 for a printed product 14 (FIG. 4). A first weakening line 18 runs parallel to the long side 16 of the rectangular plate 12, a section extending over the entire length, which is more or less 80% of the thickness of the plate 12 in the viewing direction. This forms a strip 20 which can be angled backwards and is approximately 3 cm wide, which is indicated by an arrow 22. When the rear face R of the plate 12 visible here is placed and the angled strip 22 is placed on a flat surface, a stand for a printed product 14 (FIG. 4) is formed. Thanks to the angled, one-piece strip 20 made of the rigid material of the plate 12, in spite of the second weakening line 24 running longitudinally perpendicular to the first weakening line 18, it cannot be folded in the working position. The second weakening line 24 extends over the entire width of the plate 12 and is also approximately 80% deep with respect to the thickness of the plate 12. The second weakening line 24 is not visible on the rear side R and is therefore shown in broken lines, the cut is made on the invisible front side. The plate 12 can only be folded into A4 format with the strip 20 running in the same plane as the plate 12.

The plate 12 shown in FIG. 2 for forming a stand essentially corresponds to that of FIG. 1, but additionally has two pivotable tabs 26 which are shown angled slightly to the rear. The tabs 26 are used to automatically set up the stand 10 (FIG. 4). The essentially triangular tabs 26 are punched out of the plate 12, the third weakening lines 28 run parallel to the second weakening line 24 and end in the direction of the longitudinal side 16 in the first weakening line 18.

The front side V of the plate 12 is visible in FIG. 2, the line of weakness 18 for the strip 20 is therefore not visible and is therefore shown in dashed lines. In the working position, the strip 20 is angled forward in the direction of the arrow 22, the tabs 26 rearward approximately at a right angle to the plate 12, in the direction of the arrow 30. The angle α between the punched edge 32 and the first weakening line 18 corresponds to the angle of inclination the support surface of the plate 12 forming stand. The angled strip 20 forms the support surface for the printed product 14 (FIG. 4).

3 shows a half of the plate 12 folded into the A4 format, both the strip 20 and the tabs 26 lie in the plane of the plate 12. The two halves of the strip 20 lying on top of one another cannot be angled, they are in Area of the second weakening line 24 connected to one another. The tabs 26 are also fixed in the corresponding openings; if the third weakening line 28 is designed accordingly, they cannot pivot outwards without the application of force.

Fig. 3 shows impressively how the stand finds space in the smallest space.

In the embodiment according to FIG. 3, two sheets 26 are punched out per half of the plate 12, optionally one or both plates can be angled. Through simple incisions in the corner area 34 of the tabs 26, these can be hooked together in the working position and the entire stand can thus be made more stable.

4 shows a plate 12 set up as a stand 10 with tabs 26 angled approximately at right angles to the rear. The contact surface for the printed product 14 has an angle α with respect to the vertical, which corresponds to the angle between the punched edge 32 and the first weakening line 14 (FIG. 2). The punched edge 32 of the tabs 26 lies on a flat surface 36, which is indicated by dashed lines and can be a table, for example. The angled tab 20 is not, according to the simplest embodiment, also directly on the flat surface 26, but over the longitudinally folded end 38 of the strip 20. This increases the slip resistance of the printed product 14. According to a variant, not shown, a pencil can be placed under the flap, for example, a right angle is formed between the flap 20 and the support surface of the plate 12, which is optimal with regard to the slip resistance and nevertheless allows a problem-free turning of the printed product 14. According to a further variant, not shown, the end 38 can be folded upwards, in particular with the aid of a line of weakness, not shown, from the rear in the longitudinal direction.

5 shows in the region of a line of weakness 18, 24, 28 a narrow cut 40 in the plate 12, which is formed at a depth t. The depth t makes up about 75% of the total thickness d of the plate 12. Half of the plate 12, the strip 20 or a flap 26 can now be folded in the direction of the arrow 42 without any problems. Folding in the opposite direction is practically impossible. A dashed line indicates an optionally attachable, self-adhesive plastic tape 41, which makes the area of the weakening line more tear-resistant.

In the embodiment according to FIG. 6, the plate 12 is coated with a tear-resistant, mechanically resistant PE film 46 with a thickness of approximately 0.15 mm. According to a variant, the other side can also be coated with the film or by spraying on an appropriate coating material.

In the present case, the weakening line 18, 24, 28 is cut out as a groove 44 which is wedge-shaped in cross-section and which extends completely through the core layer of the plate 12 and extends to the PE film 46. The flipping half of the plate 12, the strip 20 or the tab 26 in the direction of the arrow 42 takes place without problems until the plate halves or the PE foils lie on one another. In the direction of arrow 48, however, can be angled at most up to an angle of about 90 °, which is only suitable for strips 20 and tabs 26.

In the embodiment according to FIG. 7, opposite wedge-shaped grooves 44 are recessed on both sides of the plate 12. A strip 20 or a tab 26 can be angled on both sides up to approximately 90 °. This embodiment is not suitable for forming a first line of weakness; a strip 20 or a tab 26 can be angled on both sides in the direction of arrows 42 and 48, approximately by 90 °. This embodiment is particularly suitable for plastic plates 12.

In Fig. 8 some means for improving the slip resistance on the strip 20 of a plate are shown.

- According to a first variant, 50 foils can be glued or coatings applied as a flat anti-skid device.

- According to a second variant, embossments 52 can be shaped in the form of knobs, ribs or corrugations, which are particularly effective against a printed product or a textile base.

- According to a third variant, a cross-grooved strip 54 provides particularly effective protection against sliding. In practice, of course, only a single type of anti-skid device 50, 52, 54 is applied, on one or both sides of the strip 20.

The examples according to FIG. 8 are just a few from a large selection which perform the same function. Of course, a strip 20 has one Stand 10 only one type of anti-skid 50, 52, 54.

9 and 10 show how the punched-out tab 26 after folding over a third line of weakness 28 backwards in an optimal, i.e. is fixed to the plane of the plate 12 perpendicular position. In addition to the tab 26 for support, a locking tab 58 is punched out, which can be pivoted backward about a fourth weakening line 60. In FIG. 9, all the punched edges of the tab 26 and the locking tab 58 are accompanied by dotted lines, and all lines of weakness are dashed.

The locking mechanism can be seen from the course of the punched edges and weakening lines. For the time being, the tab 26 is folded back and held in an approximately vertical position to the plate 12. Then the locking tab 58 is folded back. A notch 62 can then be self-centering in the punched edge of the locking tab 58 in a notch 64 of the punched edge of the tab 26 and clamped there by pressing. As a result, the tab 26 is releasably fixed in the optimal position. In Fig. 10, the locked end position of the tab 26 and the locking tab 28 is shown.

The tab 26 of the stand 10 according to FIGS. 9 and 10 does not extend to the first weakening line 18. An angling in the corresponding punched edge permits a distance that is advantageous in terms of stability.

Longitudinal grooves (not shown) are formed on an adhesive strip 66, which prevents individual sheets of a printed product from sliding away.

9 and 10, only the left half of the stand 10 is shown. The folded and therefore not visible right half is mirror-symmetrical with respect to the second weakening line 24.
