BACKGROUND OF THE INVENTION

The following includes information that may be useful in understanding the present invention(s). It is not an admission that any of the information provided herein is prior art, or material, to the presently described or claimed inventions, or that any publication or document that is specifically or implicitly referenced is prior art.

1. Field of the Invention

The present invention relates generally to the field of easel and more specifically relates to a pre-wired foldable easel with a lighting system that includes an on/off switch and a dimmer switch

2. Description of the Related Art

Traditionally artists' easels are just a simple stand used to hold a canvas at an elevated and angled position so that an artist can easily paint. Traditional easels do not offer a lighting mechanism for the artist to use when the painting area lacks sufficient 20 lighting. Generally, artists have to use separate lighting stands to light up the painting area or the canvas when working in low light environments. This causes the painting area to be cluttered especially when the artist is working in a studio with other artists. When the amount of clutter increases around an easel, the chances of tipping over the easel or a light stand also increases. Additionally, when the artist is working on a detailed section, the artist needs the respective area to be clearly visible. Ideally, the artist would like to focus additional lighting to the working area so that the respective area can be clearly visible. This usually requires the artist to obtain a light stand that has a focused lighting system thus allowing the artist to move the focused lighting system in areas that requires additional lighting. When moving the focused lighting system to a specific area of the 30 canvas, the process is inconvenient for the artist as they have to reach over to the light stand that are usually positioned next to or behind the artist. Additionally, this also increases the probability of knocking over the light stand or any of the artist's supplies.

It is therefore an object of the present invention to provide a foldable easel that combats the aforementioned issues by integrating a lighting system directly onto the foldable easel. As a result, the present invention eliminates clutter and gives 5 the artist the ease of moving the lighting system to any specific area of the canvas. In addition to holding a canvas for an artist to work on, the present invention also provides the displaying apparatus with gallery quality lighting for an artwork and visual designs to be showcased in homes, businesses and galleries

DETAILED DESCRIPTION

The present invention is a foldable and portable easel with a lighting system. The present invention provides solution for limited wall space and provides multiple levels of placement for an artwork while providing essential illumination for an artwork that is placed within. As a result of the aforementioned benefits, the present invention is able to provide an improved and efficient easel compare to existing easels. The present invention comprises a foldable frame 1, a power supply system 34, a left light fixture 29, and a right light fixture 30 as shown in FIG. 1. In reference to the general configuration of the present invention, the foldable frame 1 that functions as the stand or the base of the present invention comprises a rear central rail 2, a left front rail 3, a right front rail 4, a plate 9, and a cross brace assembly 12. A proximal end 5 of the rear central rail 2, the left front rail 3, and the right front rail 4 are each hingedly connected to the plate 9 in order to form the overall shape of the foldable frame 1. The cross brace assembly 12 that stabilize foldable frame 1 is hingedly connected to the rear central rail 2, the left front rail 3, and the right front rail 4.

Additionally, the cross brace assembly 12 is positioned in between the plate 9 and a distal end 6 of the rear central rail 2, the left front rail 3, and the right front rail 4 to maintain the overall shape and structural support of the foldable frame 1. The left light fixture 29 is detachably mounted to the left front rail 3. The right light fixture 30 is detachably mounted to the right front rail 4. The left light fixture 29 and the right light fixture 30 are able to provide illumination to an artwork that is placed within the foldable frame 1 as the left light fixture 29 and the right light fixture 30 are electrically connected to the power supply system 34.

The foldable frame 1 provides the overall shape of the present invention, wherein components connections between the rear central rail 2, the left front rail 3, the right front rail 4, and the plate 9 allow the present invention to switch between an unfolded configuration and a folded configuration. More specifically, the unfolded configuration allows the user to place and support an artwork within the foldable frame 1. In particular, the distal end 6 of the rear central rail 2, the left front rail 3, and the right front rail 4 are positioned further apart from each other forming a tetrahedron pyramid shape. The folded configuration allows the user to store the present invention with minimum amount of storage space as the distal end 6 of the rear central rail 2, the left front rail 3, and the right front rail 4 are positioned adjacent to each other forming an elongated rectangular shape. Additionally, the height of the rear central rail 2, the left front rail 3, and the right front rail 4 also determine the overall height of the foldable frame 1.

In reference to FIG. 2 and FIG. 4, the plate 9 functions as a connecting member within the present invention as the left front rail 3 and the right front rail 4 are connected to a rear surface 10 of the plate 9. More specifically, the proximal end 5 of the left front rail 3 is hingedly mounted to the rear surface 10 of the plate 9 by a left lateral joint 17. Similarly, the proximal end 5 of the right front rail 4 is hingedly mounted to the rear surface 10 of the plate 9 by a right lateral joint 19. The left lateral joint 17 and the right lateral joint 19 are oppositely positioned of each other across the plate 9 in such a way that a rotational axis 18 of the left lateral joint 17 is oriented parallel to a rotational axis 20 of the right lateral joint 19. In order to form the tetrahedron pyramid shape, the plate 9 comprises a pair of perpendicular supports 11 that are vertically positioned along the rear surface 10 of the plate 9. In reference to FIG. 2, the proximal end 5 of the rear central rail 2 is hingedly mounted to the pair of perpendicular supports 11 by a rear joint 21 that is positioned in between the left lateral joint 17 and the right lateral joint 19. However, a rotational axis 22 of the rear joint 21 is oriented perpendicular to the rotational axis 18 of the left lateral joint 17 and the rotational axis 20 of the right lateral joint 19. As a result, the left front rail 3 and the right front rail 4 are able to radially extend outward about the left lateral joint 17 and the right lateral joint 19 respectively. The rear central rail 2 can radially extend backward about the rear joint 21, resulting the tetrahedron pyramid shape. In reference to FIG. 5-7, the foldable frame 1 further comprises a plurality of no-slip foot members 8 to improve the traction between the foldable frame 1 and the resting surface that the present invention is placed upon. More specifically, each no-slip foot member 8 is adjacently connected to the distal end 6 of the rear central rail 2, the left front rail 3, and the right front rail 4. The plurality of no-slip foot members 8 ensures that the foldable frame 1 does not slip or move laterally on the resting surface. The cross brace assembly 12 limits how far the rear central rail 2, the left front rail 3, and the right front rail 4 can extend about the respective rotational axis without compromising the structural integrity of the present invention.

In reference to FIG. 3, the cross brace assembly 12 comprises a rear brace 13, a left front brace 14, a right front brace 15, and a mounting hub 16. The rear brace 13, the left front brace 14, and the right front brace 15 are interconnected to each other by the mounting hub 16 so that the foldable frame 1 can switch between the folded configuration and the unfolded configuration, without putting excessive pressure on the left lateral joint 17, the right lateral joint 19, and the rear joint 21.
