Ultraviolet Radiation Blocking Sheet

BACKGROUND OF THE DISCLOSURE

Field of the Disclosure

The disclosure relates to ultraviolet radiation blocking devices and more particularly pertains to a new ultraviolet radiation blocking sheet for blocking ultraviolet radiation while allowing passage of visible light.

SUMMARY OF THE DISCLOSURE

An embodiment of the disclosure meets the needs presented above by generally comprising a film that is substantially transparent to light that has a wavelength of 495 to 570 nanometers. The film also is substantially absorbent of light that has a wavelength shorter than 495 nanometers. The film is configured to position between a light source and an object to be protected from ultraviolet radiation. The film absorbs the ultraviolet radiation emitted from the light source while allowing light that has a wavelength of 495 to 570 nanometers to pass through the film to illuminate the object.

There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.

The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.

DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular to <figref idref="DRAWINGS">FIGS. 1 through 5</figref> thereof, a new ultraviolet radiation blocking devices embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral <b>10</b> will be described.

As best illustrated in <figref idref="DRAWINGS">FIGS. 1 through 5</figref>, the ultraviolet radiation blocking sheet <b>10</b> generally comprises a film <b>12</b> that is substantially transparent to light that has a wavelength of 495 to 570 nanometers. The film <b>12</b> also is substantially absorbent of light that has a wavelength shorter than 495 nanometers. In one embodiment, the film <b>12</b> also is substantially absorbent of light having a wavelength longer than 570 nanometers. In another embodiment, the film <b>12</b> is semi-rigid, such that the film <b>12</b> is formable into a container <b>14</b>.

The container <b>14</b> has a bottom <b>16</b>, an open top <b>18</b> and an annular wall <b>20</b> that define a holding space <b>22</b>. The container <b>14</b> is configured to house the root system of a plant within the holding space <b>22</b> while allowing the root system to be inspected through the annular wall <b>20</b> and the bottom <b>16</b>. The bottom <b>16</b> is circularly shaped. The open top <b>18</b> is dimensionally larger than the bottom <b>16</b>, such that the container <b>14</b> is conical.

The sheet <b>10</b> also comprises a cover <b>24</b> that is complementary to the container <b>14</b>. The cover <b>24</b> is reversibly couplable to the container <b>14</b> to cover the open top <b>18</b>. In one embodiment, the cover <b>24</b> has an annular sidewall <b>26</b> extending downwardly from a top face <b>28</b> to a bottom face <b>30</b>. The bottom face <b>30</b> is open. The open top <b>18</b> of the container <b>14</b> is positioned for insertion of the cover <b>24</b> such that the annular sidewall <b>26</b> of the cover <b>24</b> abuts the annular wall <b>20</b> of the container <b>14</b>.

An opening <b>32</b> is positioned in the cover <b>24</b> and is configured for a leaf portion of the plant to protrude from the container <b>14</b>. An air pump <b>34</b> is fluidically connected to the holding space <b>22</b> and is configured to circulate fresh air through the holding space <b>22</b>.

In one embodiment, the container <b>14</b> comprises a plurality of pots <b>36</b>. Each pot <b>36</b> is substantially cylindrically shaped. The plurality of pots <b>36</b> comprises eight pots <b>36</b>.

The present invention comprises a stand <b>38</b> that is configured to house the plurality of pots <b>36</b>. The stand <b>38</b> comprises a panel <b>40</b> that is rigid and substantially rectangularly shaped. A plurality of legs <b>42</b> is coupled to and extends from a lower face <b>44</b> of the panel <b>40</b>. The plurality of legs <b>42</b> comprises legs <b>42</b> positioned proximate to each corner <b>46</b> of the panel <b>40</b>. A retainer <b>48</b> is coupled to and extends from an upper face <b>50</b> of the panel <b>40</b>. The retainer <b>48</b> is positioned on the panel <b>40</b> such that the retainer <b>48</b> is positioned to maintain the pots <b>36</b> on the upper face <b>50</b> of the panel <b>40</b>.

The retainer <b>48</b> comprises a plurality of verticals <b>52</b> that is coupled to and extends perpendicularly from the panel <b>40</b>. A perimeter rod <b>54</b> is coupled to and extends between each of the verticals <b>52</b>. The perimeter rod <b>54</b> is coupled to each vertical <b>52</b> distal from the panel <b>40</b>.

In one embodiment, a plurality of cross supports <b>56</b> is coupled to and extends between opposing sides <b>58</b> of the perimeter rod <b>54</b>. The cross supports <b>56</b> are substantially evenly space between opposing ends <b>60</b> of the perimeter rod <b>54</b>. The plurality of cross supports <b>56</b> comprises three cross supports <b>56</b> that define four compartments <b>62</b>. Each compartment <b>62</b> is configured to house two pots <b>36</b>.

In use, the film <b>12</b> is configured to position between a light source and an object to be protected from ultraviolet radiation. The film <b>12</b> absorbs the ultraviolet radiation emitted from the light source while allowing light having a wavelength of 495 to 570 nanometers to pass through the film <b>12</b> to illuminate the object.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.

Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
