Description

Display device and easel folding.

Field of the Invention

This invention relates to an easel for support a flat plank for images in a vertical way according to the preamble of claim 1 as well as to a self-exhibiting display device comprising said easel.

Background of the invention

A variety of folding structures are known. support. For example, US 3 508 734 describes a sheet flat material, which is formed with parallel folding lines and longitudinal to provide a front panel and sections wing integrals, in which wing sections are made notches in their corners, and when they fold so that they are essentially parallel, and perpendicular to the front section, they are held in position by an elastic band hooked on the notches, and pulling the wings elastically against a spacer element or extender. In such a way, from a flat, foldable sheet, the structure can be mounted by putting the elastic bands in the notches and letting the wings connect against the spacer element.

Large flat display boards are used for images to display advertising posters, or to display Life-size images of movie actors, runway models, Popular musicians, similar scientific or novelty objects for decorative purposes The large flat plank for images can measure more than 1.5 m (five feet) by 0.6 m (two feet) in size, and They are usually made of corrugated cardboard material. For support said large flat plank for images in one position vertical on a floor, an easel adapts on its surface rear to form an integral composite device. The easel It is also commonly made of corrugated cardboard material that It has constituent parts to form a rigid support base. He composite device can be folded double to a folded state for transport or storage. However, an inconvenience common in such a device is that after it has been folded doubly to the folded state, it still has a relatively size big. For a life-size flat display, the device compound, in the folded state can measure more than 0.6 m (two feet) by 0.6 m (two feet) by 5 cm (two inches), which is I would consider it as an oversized package for services postal and transport, and is not particularly conducive to send through the postal service due to the high surcharge imposed in an "oversized" package. The main difficulty with such known display devices is that the material of thick corrugated cardboard should also be used to make the easel to provide the necessary strength to support the plank for images in the vertical position. In addition, the dimensions of easel must be compatible large to provide the support required for the large corrugated cardboard board to images. Commonly, the easel has one or more support panels verticals that have a vertically tapered shape, narrow in the upper part and tapered towards a large lower base part. Fold such thick material in more than one way of double folding even a bent state would intrinsically destroy its resistance, so that it would lose the necessary resistance when later it is deployed to the mounted position from the folded state.

Summary of the invention

A main object of the present invention is provide a combined device of a large flat plank to images and easel that folds into a plurality of lines transversal to a compact size. This object is achieved with the characteristics of claim 1, whose embodiments are the subject of dependent claims 2 to 9.

The composite device of the present invention has an easel fixed to the back surface of a image board and is operated to support the latter of a vertical way on a floor, the easel comprising a flat plank that has an easel design pattern stamped on the same. The design pattern has constituent parts that are deployed to form the easel in a mounted state. The parts  constitutive include two elongated side panels substantially rectangular that extend throughout the longitudinal dimension of the flat plank. A body part Central extends between the side panels. Body part center is fixed to the back surface of the image board. Two parallel and vertical fold lines are located between the central body part and side panels such that these side panels are deployed along these lines of Vertical folding to form the right side panel and panel left side of the easel located substantially perpendicular to the board for images. A plurality of horizontal clamp elements in the central body part and are located between the side panels. Each element of clamp unfolds along a folding line transverse to a substantially horizontal position that extends between the side panels. Clamp elements cooperate with the side panels to keep the easel in a been mounted A plurality of fold lines is formed transverse in the flat plank and are located between the elements clamp so that the composite device can be folded into these cross fold lines to a bent state compact.

Detailed description of the preferred embodiments

With reference to the drawings where they are reference numbers designate corresponding parts in the various views, the stand 10 of the present invention is formed using a design pattern stamped on a cardboard for easel Made of cardboard, corrugated cardboard or similar flat cardboard material. The stand 10 is fixed to the rear surface 11 of a plank image display plane 12. The image board 12 is commonly a large corrugated cardboard that has a size image natural provided on its front surface. The board for Images 12 may also have the same image shape. Be It shows a rectangular plank for easy illustration. He easel design has a generally rectangular shape with two lateral extensions of truncated triangles 13 and 14 formed in its lower part. The bottom edges 15 and 16 of the lateral extensions 13 and 14 respectively lean preferably slightly up and out about 5 degrees relative to the horizontal plane as best shown in the Figure 1. A vertical rectangular pattern is formed in the center of the easel design. The pattern is formed by two lines of mutually parallel vertical bending 17 and 18 extending by its entire longitudinal vertical dimension, thus forming two panels 19 and 20 generally L-shaped sides with extensions laterals 13 and 14 located respectively in their part lower.

Side panels 19 and 20 are not fixed to the back surface 11 of the image board 12, and can fold or roll out on the surface back 11 of the image board 12 in the fold lines verticals 17 and 18 respectively to a substantially position perpendicular to the back surface of the plank for images to provide side stand vertical support panels required The easel 10 is divided into three parts of it length, namely a bottom part 21, a central part bottom 22, a top center part 23, and an equal or more part small top 24. The top 24 is smaller because the image to be supported in this part of the easel normally It has a smaller size than the main central part of the image. A horizontal folding line 25 separates the bottom 21 and the lower central part 22; a second folding line horizontal 26 separates the lower center part 22 and the part upper central 23; and a third horizontal folding line 27 separates the upper central part 23 and the upper part 24. The horizontal fold lines 25, 26, and 27 align with the associated horizontal fold lines 28, 29 and 30 formed respectively on the image board 12 such that the composite display device comprises both the easel 10 like the image board 12 and together they can be folded to a state folded along these horizontal fold lines and lines associated folding. Double fold lines can be provided 25 and 27 to increase the folding capacity of the easel.

The rectangular central body part 31 of the easel 10 is fixed to the back surface of the plank to images with glue or other conventional means. A slot horizontal 32 extending over the entire width of the part central 31 is formed along the fold line 25; a second horizontal groove 33 extending over the entire width of the central part 31 is formed along the folding line 26; Y a third horizontal groove 34 that extends throughout the width of the central part 31 is formed along the line of folding 27. Horizontal grooves 32, 33, and 34 increase the folding capacity of the easel along the lines of horizontal folding due to the reduction of the material to fold.

A horizontal crossbar generally in shape rectangular 35 is formed in the upper central part 23 of the part of central body 31. The cross member 35 has a folding line horizontal 36 so that it can roll out with respect to the central part 31 in the fold line 36 to form a clamp that extends in a horizontal position between the vertical side panels 19 and 20 and perpendicular to the backboard surface for images. A second crossbar similar horizontal rectangular generally 37 is formed in the part lower center 22. The cross member 37 has a folding line horizontal 38 so that it can roll out with respect to the central body part 31 in the fold line 38 to form a second clamp that extends in one position horizontal between vertical side panels 19 and 20 and perpendicular to the back surface of the image board. Two Similar rectangular crossbars 40 and 41 are formed in the part lower part of the central body part 31. The crossbars 40 and 41 they have horizontal fold lines 42 and 43 such that they can turn out with respect to the body part central 31 to form crossbars that extend in one position horizontal between vertical side panels 19 and 20 and perpendicular to the back surface of the image board. Those skilled in the art can appreciate that although preferably two crossbars are formed at the bottom 21 to provide a strong base of support for the easel, a crossbar may be sufficient for this purpose.

Two openings 44 and 45 are formed in the panel vertical side 19 and are located one above and the other by below the horizontal folding line 36 of the crossbar 35. Similarly, two openings 46 and 47 are formed in the side panel vertical 20 and are located one above and the other below the horizontal folding line 36. Similarly, two are formed openings 48 and 49 in the vertical side panel 19 and are located one above and the other below the folding line horizontal 38 of crossbar 37; and two openings 50 and 51 are formed in the vertical side panel 20 and one above and the another below the horizontal folding line 38. Two are formed openings 52 and 53 in the vertical side panel 19 and are located one above and the other below the folding line horizontal 42 of cross member 40; and also similarly form two openings 54 and 55 in the vertical side panel 20 and are located one above and the other below the folding line horizontal 42. Two openings 56 and 57 are formed horizontally adjacent to the lower edge of the vertical side panel 19; Y similarly two openings 58 and 59 are formed horizontally adjacent to the bottom edge of the vertical side panel 20.

Two openings 60 and 61 are formed adjacent to the free edge of the crossbar 35. Similarly, two openings are formed 62 and 63 adjacent to the free edge of the cross member 37; two are formed openings 64 and 65 adjacent to the free edge of the cross member 40; and they form two openings 66 and 67 adjacent to the free edge of the crossbar 41. The stand 10 can be mounted by first deploying the vertical side panels 19 and 20 in the fold lines verticals 17 and 18 until they are generally positioned perpendicular to the back surface 11 of the image board 12. The crossbars 35, 37, 40 and 41 then turn towards out to a horizontal position that extends between vertical panels 19 and 20. The elongate fasteners 68, 69, 70, 71, 72, 73, 74 and 75 are then threaded through the openings 44 to 67 to keep the crossbars in position horizontally deployed to keep the easel in the state mounted. The fasteners are ropes of a length default with a crossbar 76 provided in its two ends so that they can be easily threaded to through the various openings in vertical panels 19 and 20 and the crossbars 35, 37, 40 and 41. After threading through the openings, the crossbars 76 will be positioned transversely supporting the openings of the side panels vertical 19 and 20 to retain the easel in the assembled state. The device composed of easel and display board Images can be folded to a folded state when removing items clamping, returning the side panels and crossbars to the state flat bending and folding the four parts of the composite device of display along the horizontal folding lines.

Fasteners can be provided elastic so that the elastic resistance of elasticity  of the fasteners would normally keep the crossbars and vertical panels in a secured assembled state. The device composed of easel and display board images would lean back on top because of that the sloping bottom edges 15 and 16 of the panels vertical rest on the ground to provide a position more stable vertical. The easel composite device and Image display board can be folded to the folded state without removing the elastic fasteners. This can be get by first pressing the central part of the side panels 19 and 20 near the folding line 26 to a folded position, against the elastic resistance of fasteners, to stay flat against the back surface 11 of the image board 12, and while Hold them in such a collapsed sunken position, fold the central part lower 22 and the upper central part 23 towards each other at along the folding lines 26 and 29 as shown by the arrows 77, 77A, 78 and 79 in Figure 5. The top 24 can then fold towards the upper central part 23 along the fold lines 27 and 30 as shown by the arrows 80 and 81 and, similarly, the bottom part 21 can be folded towards the lower central part 22 along the fold lines 25 and 28 as shown by arrows 82 and 83. The device whole display compound can then be folded to a state compact folded that has an acceptable size to transport it to through regular postal or distribution services. He composite display device in the folded state is self-locking simply by holding the top edge of the plank to 10 images and lifting it up; the elasticity of fasteners will automatically pull the panels sides and crossbars to return to perpendicular position to the back surface of the image board to place the easel in the folded state.

Due to the unique construction, the easel of The present invention can be made of any cardboard material flat or laminate and still provide strong support for the board for images.
