Description

DESCRIPTION

PROJECTION DEVICE WITH INTEGRATED SCREEN FOR

LANDSCAPE VIEW

TECHNICAL SECTOR

The present invention belongs to the audiovisual sector and more specifically to image projectors and projection screens.

The main object of the present invention is a device that allows images to be projected on a horizontal screen for viewing in a lying position (one or more people).

BACKGROUND OF THE INVENTION

There are many projectors that generally project on a vertical screen and many of them also allow projection in other directions and on other surfaces. However, there are no integrated "screen projector" devices on the market that allow a comfortable and adequate display of images of a certain size in a lying position and that are easy to assemble and move/transport.

The solution of the present invention makes it possible to drastically reduce the cost (and therefore the price) of the combination of the two projector and screen components, by reducing the size and requirements of both. Likewise, the present invention greatly facilitates the assembly, disassembly and portability/transportation of the assembly, thus making it feasible to assemble and disassemble it (at least partially) frequently or even daily.

On the other hand, there are comparable alternatives, such as mobile and tablet supports, or glasses that allow viewing images. However, the size of mobile phones and electronic tablets is smaller than the proposed solution, being the relative weight generally much higher than that of a projection screen; and it is difficult to assess the impact that the frequent use of glasses to view images can have on the eyes. These alternatives have limitations in the size of the images and for the use of several people, making it more difficult to share an audiovisual work, a video game or a video call.

The present invention is similar to classic projection systems (such as a cinema, or a projector for home use), but adds the possibility of enjoying images and sound in a natural resting position and considerably simplifies its installation.

. EXPLANATION OF THE INVENTION

The projection device object of the invention comprises: a projector and screen support that rests on the floor, on another horizontal surface (for example a bed or a sofa), or that is fixed to some other point with a clip or system similar, and a screen whose position, height and angle can be easily adjusted. The normal position of the screen is horizontal or slightly tilted.

The main advantages of this invention are summarized as follows:

• The device allows you to enjoy audiovisual works (eg movies) or video games or video calls comfortably while lying down or lying on a bed or sofa.

• The device allows you to maintain the same position as when sleeping on your back, without forcing your neck or back, but in a natural resting position.

• The projection distance is generally relatively short compared to the distance to a projection wall or ceiling, facilitating the requirements of projecting quality images.

• The size of the projected image is considerable, being larger than that of an electronic tablet or mobile phone, for greater immersion and enjoyment of audiovisual works, video games or video calls.

• The stand is light but stable and can be easily attached and removed.

• The device is easy to transport, being possible to fold it, thus occupying very little space.

The device consists of four main parts: the base or fixing clamp , the stand or main body (rod or mast), swan neck, goose neck or similar, the projector support and the screen . The device may include a small projector.

In a preferred embodiment, the base is of the tripod type and rests on the floor, leaving the support on the edge of the bed or sofa.

In another preferred embodiment, the support is fixed to a fixed point (for example, the head of the bed or a bedside table) by means of a clip or similar fixing system.

In another preferred embodiment, the base rests on four adjustable points (in spacing and height) to place two by two on both sides of the lying spectator.

The support or main body is supported or rests connected to the base or clamp and is the main piece (vertical or flexible), to which the projector support and also the screen are connected.

The projector support is a piece that is placed in a more or less horizontal position, more or less perpendicular to the support or main body, whose height or position can be adjusted. Its function is simply to support the projector at the desired height and also allows you to adjust the inclination of the projector.

Finally, the screen can be folded or unfolded for use, and its height and tilt can be adjusted. When the screen is unfolded, it can be fixed with a side rod or similar fixing system.

To increase stability, it is possible to add a rod in the opposite direction to the screen (in relation to the mast) that supports a counterweight (adjustable distance), but due to the reduced weight of the screen, it is not generally necessary.

Through the fixing mechanism of the rod (or cylinder) of the screen next to the support, you can change the tilt or orientation of the screen.

In a preferred embodiment, the screen unfolds by separating two parallel cylinders or rollers, or a cylinder (where it is rolled up) and a rod, and it is possible to fix it in various positions.

BRIEF DESCRIPTION OF THE DRAWINGS

To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of its practical embodiment, a set of figures is attached as an integral part of said description. where, by way of illustration and not limitation, the following has been represented:

Figure 1 shows a schematic view with a possible embodiment of the device according to the present invention in elevation (A), plan (B), profile (C) and isometric or three-dimensional view (D).

Figure 2 shows a schematic view with another possible embodiment of the device assembled with a fixing clip and a type 1 swan-neck support.

Figure 3 shows a schematic view of the device in which the exploded view of the different elements in which it is composed can be seen.

Figure 4 shows a schematic view with another possible embodiment of the device with fixation clip and swan-neck support type 2.

Figure 5 shows a schematic view with another possible embodiment of the device with a fixing clip and gooseneck support.

Figure 6 shows a schematic view with another possible embodiment of the device with a four-point base for a bed or sofa.

Figure 7 shows a schematic view of the screen folded and unfolded with a cylinder, end and fixing rod.

Figure 8 shows a schematic view of the screen folded and unfolded with two cylinders and fixing rod.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the aforementioned figures, and in accordance with the adopted numbering, an example of a preferred embodiment of the invention can be observed, which comprises the parts and elements that are indicated and described in detail below.

Thus, as can be seen in figures 2 and 3, a possible preferred embodiment of the projection device (1) essentially comprises the following elements:

• A fixing clip (2)

• A support or main body (3) with a gooseneck that allows the screen to be easily placed in the desired place.

• A projector mount (4) that can also be adjusted and oriented to the desired position.

• A drop-down screen (5) on which it is projected, which is connected to the projector by means of a mechanism that allows it to be rotated and oriented in the desired position. The screen can be disconnected from the mechanism and can be folded into a cylinder or unfolded and fixed by means of a rod. As the rod is removed and the end of the screen is released, the screen rolls onto the cylinder.

The present invention is capable of industrial application. It is a device that, apart from the projector, is made up of elements that are relatively simple to manufacture and have a moderate manufacturing cost. Assembly is also relatively simple, and its industrial application is perfectly feasible. The elements of which the present invention is made up (base, clamp, supports, projection screen...) are manufactured in the industry, but not in the combined and integrated way that is proposed.
