This invention relates to cellphone accessories. Specifically, this invention is an accessory that shades a cellphone display during times of intense sunlight.
Cellphones, pads, and tablets (“Portable Electronic Devices” or “PEDs”) are ubiquitous. However, using them outside can be challenging. Almost everyone has tried to use a PED at the beach or in a park or even on a city street in the bright sunlight. Sunlight obscures the screen of a PED, making it difficult or impossible to use in certain situations. The screen can be washed out, the text hard to read.
Users of PEDs have various strategies for using them out of doors. Some users skulk in the shade, under awnings or in the shadow of buildings. Some users turn up the brightness on the display, which greatly affects the battery life, and provides a substantially sub-optimal experience. With the PED screen turned up to full brightness on a sunny day, the experience is still washed out and hard to read. Sunglasses or on-screen filters do not solve the problem, either.
These various methods all fail for one simple reason: the luminance of the sun is orders of magnitude greater than the luminance of a display screen on a Portable Electronic Device. Luminance is the visible light flux radiated from a point light source per unit solid angle and per unit projected area perpendicular to the specified direction. The only viable solution is to provide a temporary shade element which limits the sunlight projected perpendicular onto the screen of a PED.
The current offerings are all substandard for one reason or another. Some provide a shade which is but a fraction of that which is needed. Some require that the PED be held at a specific angle. What the market is looking for is a temporary sunscreen that can shade the screen of a PED under almost all conditions. The solution should be inexpensive, easily removable, and usable with any PED.
This summary is intended to disclose the present invention a segmented personal electronic device canopy. The segmented personal electronic device canopy can be a stand-alone device, or it can be integrated into a cellphone case. The segmented personal electronic device canopy can fit along the short-edge of a personal electronic device or along the long-edge of a personal electronic device. The segmented personal electronic device canopy can be fitted for a cellphone, tablet, or pad.
The segmented personal electronic device canopy has two identical rotational joints disposed opposite one another on the same rotational axis. The segmented personal electronic device canopy has a rotational frame constructed from a plurality of u-shaped ribs. One u-shaped rib, disposed most forward with respect to the screen of the personal electronic device, is designated the front terminal rib. The front terminal rib has a front terminal transverse member and two front terminal radial members. Each rib has a transverse member and two radial members. Each transverse member has two ends. At one end, the transverse member attaches orthogonally to a first radial member. At a second end, the transverse member attaches orthogonally to a second radial member. The two radial members being parallel with one another. Each of the two radial members attaches to a rotational joint. Each rib is substantially u-shaped and the transverse members and two radial members can be continuous. The connection between the transverse members and two radial members can be filleted. At a minimum, the segmented personal electronic device canopy has a front terminal rib and a rear terminal rib.
The rotational frame of the segmented personal electronic device canopy is covered with a flexible material. The flexible covering is attached to the transverse members and radial members of each of the plurality of u-shaped ribs. The segmented personal electronic device canopy has at least one pair of adjacent ribs. Each adjacent pair of ribs has an adjacent pair of transverse members, and two adjacent pairs of radial members. The flexible covering covers the rotational frame between each set adjacent transverse members. The flexible covering is affixed to each transverse member. The flexible covering covers the rotational frame between each set of adjacent radial members. The flexible covering is affixed to each radial member. The flexible covering between each set of adjacent transverse members is rectangular while the flexible covering between each set of adjacent radial members is triangular. The flexible covering terminates at the front terminal transverse member by wrapping around the front terminal transverse member. The flexible covering is then affixed with glue or it is sewn into place in order to secure it. The flexible covering limits the travel of the rotational frame.
The rotational joints allow the ribs of the segmented personal electronic device canopy to be rotated into the open or closed position. The segmented personal electronic device canopy can be opened, closed, or partially opened. When opened, the adjacent ribs are rotated as far as possible from one another, being stopped by the tension provided by the flexible covering, which is affixed to each transverse member and each radial member. When closed, the ribs are brought into near proximity with one another, collapsing the segmented personal electronic device canopy. A partially opened configuration is between the opened configuration and the closed configuration. In the closed configuration, the segmented personal electronic device canopy does not block sunlight from hitting the screen.
The transverse ribs and radial ribs can be constructed from a variety of materials including, but not limited to, steel, spring steel, zinc, aluminum, acrylonitrile butadience styrene (“ABS”), polycarbonate (“PC”), polypropylene (“PP”), polyamides (“nylon”), and polyvinyl chloride (“PVC”). The flexible covering is fabricated from a flexible material including, but not limited to, cotton, a polyester-cotton blend, polyester, polyimide, rayon, spandex, aramide fibers, polyimides, and nylon.
The present invention is attached to the cellphone using an integrated cellphone case, or as a stand-alone device.
