     FIELD OF THE INVENTION 
       [0002]    The present invention relates generally to a system and device for use in a security area, and more particularly, to a rack system and holding device for placing various objects which are processed through a security area. 
       BACKGROUND OF THE INVENTION 
       [0003]    Security areas are typically encountered in places such as an airport security terminals, courthouse entrances and various other places where a person and their luggage or personal items may need to be searched prior to entering or leaving a particular room or area of a building. These security areas typically involve the steps of a person moving through a metal detector area and removing various items from their clothing, pockets or luggage and placing them in a separate area to be either hand checked or machine checked. It is common that people traveling through security areas, such as those in an airport security terminal, may be carrying electronic devices and in particular laptop/notebook-sized computers. These laptop computers are delicate devices which should not be dropped or jostled in an excessive amount as they can be damaged. It is very common that people traveling on business through airport security terminals will have such items sized like a laptop computer so that they can later do work on the plane. The person may have personal items such as wallets, keys, change, cell phones, PDAs and other small bags that need to be checked. These items are typically loose objects that can easily be lost or damaged if not handled in a safe manner. 
         [0004]    After the person removes these items from their pockets they are usually placed into a tray or small container that is then either checked by the security personnel by hand or by an x-ray machine or other similar device. The trays that are typically used are non-standardized small trays. In addition, if the person has any electronic equipment such as a camera, a laptop computer or any other device with may have to be checked by the security personnel these items are sometimes put in a larger tray to be later hand checked by the security personnel or passed through an x-ray device. 
         [0005]    A disadvantage to the present system used in security areas is that the trays for holding laptop computers are not part of a uniform system and do not protect the items from possible damage. Therefore, it is possible that multiple size trays that do not in any way correspond with one another may be used at a security area thus making storage of the trays when they are not in use cumbersome. A disadvantage to a non-standardized tray system is that when the trays are to be stored they may take up passenger access areas, thereby causing further waiting time as the security personnel moves the unused trays so that a person may pass through a passenger access area. Further it is common that there are inadequately-sized trays for holding large items such as laptop computers, thereby increasing the chance of the computers being damaged by being placed on a conveyer belt without being placed in a tray through an x-ray machine. Also, the time taken to search for a possible adequately-sized tray creates inefficiency and extends the waiting time while a person is passing through a passenger access area. 
         [0006]    Another disadvantage of the present system is that after the trays are used and the contents are emptied the tray must then be brought to a separate area of the security area and there is no system for transporting, storing and organizing for easy access to these trays especially if there are large numbers of them, and since the trays may be of various sizes, they may be cumbersome to transport and take up an excessive amount of space. 
         [0007]    A disadvantage to the prior system is that the trays which are being used typically are plain trays and do not utilize space provided on the trays to generate additional revenue such as revenue which can be derived from advert/sing on the trays. 
         [0008]    There exists a need for a system for a security area for moving the trays from a starting position to an ending position which allows the trays to be efficiently utilized, gathered and stored to be later used again. 
         [0009]    There is also a need for a standardized sizing of the tray to allow for easier transport of the trays when they are not is use and also to provide a cleaner aesthetic appearance. 
         [0010]    There is a need for uniformity from airport to airport to assist in the movement of people through the security checkpoints and also in the security process itself.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0039]    It is to be understood that the present invention is not limited to the particular methodology, compounds, materials, manufacturing techniques, uses, and applications described herein, as these may vary. It is also to be understood that the terminology used herein is used for the purpose of describing particular embodiments only, and is not intended to limit the scope of the present invention. It must be noted that as used herein and in the appended claims, the singular forms “a,” “an,” and “the” include the plural reference unless the context clearly dictates otherwise. Thus, for example, a reference to “a tray” is a reference to one or more tray and includes equivalents thereof known to those skilled in the art. Similarly, for another example, a reference to “a step” or “a means” is a reference to one or more steps or means and may include sub-steps and subservient means. All conjunctions used are to be understood in the most inclusive sense possible. Thus, the word “or” should be understood as having the definition of a logical “or” rather than that of a logical “exclusive or” unless the context clearly necessitates otherwise. Structures described herein are to be understood also to refer to functional equivalents of such structures. Language that may be construed to express approximation should be so understood unless the context clearly dictates otherwise. 
         [0040]    Unless defined otherwise, all technical and scientific terms used herein have the same meanings as commonly understood by one of ordinary skill in the art to which this invention belongs. Preferred methods, techniques, devices, and materials are described, although any methods, techniques, devices, or materials similar or equivalent to those described herein may be used in the practice or testing of the present invention. Structures described herein are to be understood also to refer to functional equivalents of such structures. All references cited herein are incorporated by reference herein in their entirety. 
         [0041]    The present invention provides a tray and a system that can be used in security areas to provide efficient movement of loose items, laptop computers and electronic equipment from a starting point to an ending point. Specifically, the present invention may be used in an area such as an airport security checkpoint that may have a metal detector present that a person has to walk through. As the person walks through the security checkpoint they may have to remove such items such as wallets, keys, change and other small objects which are placed into a tray which is either then hand checked or placed through an x-ray machine separate from the metal detector. At the same time, if a person has a item such as a laptop computer or electronic equipment such as a video camera or digital camera, they are instructed to place such items into a larger size tray which is then passed through an x-ray machine and/or hand checked. 
         [0042]    The present invention allows for a system of uniform sizing of the trays in which items are to be placed so that the trays may easily be stacked and transported after they are used. The trays also have specified areas to allow for advertising materials to be attached. These advertising materials may be changed as often as necessary so that different companies&#39; advertisements can be represented on the trays without the need for manufacturing new trays. 
         [0043]    In an alternative embodiment the advertising materials can be permanently attached to the trays. The trays can be a disposable type that are replaced after the advertisement becomes outdated or worn and a new tray is made. 
         [0044]    The present invention has various sized trays which can be used to hold larger items such as cameras, laptop computers or purses and a second smaller size which can be used when items such as keys, wallets, cell phones, PDAs and watches are to be removed and placed in a tray for inspection. 
         [0045]    The present invention also involves a system for transporting the trays and using the trays of the present invention from the starting point in the security checkpoint to the ending point in the security checkpoint. The system includes a first tray or cart that holds several empty trays in a organized stacked manner so that a tray can be removed when needed. The tray is then used by the user and passes through the security checkpoint. After the contents are taken out of the tray the empty tray is then inserted into a second rack that is identical to the first rack. The trays are then stacked in the second rack so that the empty trays are conveniently stored for later use. After the second rack is completely filled with empty trays the second rack can be moved to the position of the first rack, and the empty trays are ready to be used again as needed. 
         [0046]    The present invention provides a cost effective way of providing security trays for a security checkpoint while at the same time generating revenue from the advertising that is contained thereon. Further, the present system provides an efficient system for moving the trays for use and removal after they are used. 
         [0047]    Security checkpoints are both a time consuming and frustrating part of traveling for frequent fliers and people on vacation alike. The present invention provides a system of speeding up the process of processing people through these checkpoints to decrease the likelihood of delays for travelers. The present invention also has the advantage of increasing passenger flow through checkpoints and increasing traveler satisfaction due to the lack of delays. 
         [0048]    Referring to  FIG. 1 , the side elevation view of a computer tray first embodiment is shown. The tray  10  has a base  12  having upwardly extending walls  14  extending therefrom. In a preferred embodiment, base  12  can have a rectangular or square shape. Referring to  FIG. 2 , there is a first wall  16  and a second wall  18  positioned substantially parallel to the first wall. The first wall  16  and second wall  18  are connected to each other by a substantially perpendicular third wall  20  and a fourth wall  22  parallel to the third wall  20 . Referring to  FIG. 1 , the walls  14  terminate at an upper lip  46 . 
         [0049]    Referring to  FIG. 2 , attached adjacent the first wall  16  and second wall  18  can be an extended portion to form a handle  30  so that the tray can be easily moved by the user. The tray can be made of plastic by injection molding or in the alternative by stamping out of PVC or a similar material. However, any method of making the tray can be used. The tray can be made of a clear or translucent plastic if desired so that the contents in the tray can always be seen by the security personnel. However, any rigid material can be used to make the tray. 
         [0050]    Referring to  FIG. 1 , in a preferred embodiment the base  12  has a top surface  24  and a bottom surface  26 . Referring to  FIG. 3 , the top surface  24  can have a padding material  28  positioned thereon so that any objects placed with the tray  10  are cushioned by the padding  28 . Padding  28  can be of a rubber or neoprene type material to absorb any shock that the objects inside may experience when moving the tray  10 . However, it is envisioned that any material which cushions and absorbs vibration can be used. The bottom surface  26  of the base  12  can have a non-marking material  29  placed thereon so that the tray  10  does not scratch or damage any surface which the tray  10  is placed upon. It is envisioned that both the top padding  28  and bottom padding  29  can be attached by using an adhesive, Velcro® or any other means provided that the padding is securely attached to the tray  10 . In a more preferred embodiment on the top surface  24  of the base  12  it is envisioned that advertisement material  41  can be placed upon either the top surface  24  or on top of the padding  28 . This advertisement can be held on by the use of a semi-permanent adhesive, clips or a Velcro® type attachment. 
         [0051]    Referring to  FIG. 3 , in an alternative embodiment, the advertisement material  41  can be permanently attached to the top of the padding  28 . The advertising material can be permanently imprinted on the padding  28  or (referring to  FIG. 1 ) on the top surface  24  if a padding  28  is not used. It is envisioned that the advertisement can be permanently attached using either a permanent adhesive or another method of imparting a printing on the material such as sublimation or silk-screening. Referring to  FIG. 3 , it is also envisioned that the advertisement itself could be molded into the padding  28  or (referring to  FIG. 1 ) the top surface  24  of the base  12 . 
         [0052]    Referring to  FIG. 2 , the tray  10  can also include an identification number  13  which is used to identify the specific tray  10  used by a specific person. It is envisioned that each tray  10  has its own identification number  13  that is unique to it, so that when a person places their items in the tray  10 , it can later be easily identified as containing the items that the person put into it. In a preferred embodiment the identification number  13  can be located on the one of the (referring to  FIG. 1 ) upstanding walls  14 . However, (referring to  FIG. 2 ) the number  13  can be located anywhere that is visible on the tray  10 . 
         [0053]    Referring to  FIG. 1 , in a preferred embodiment, positioned at each comer between each of the individual upstanding walls  14  is (referring to  FIG. 2 ) an interior support post  43  at the comers. These support post  43  are preferably positioned adjacent the intersection of each wall and extend upwardly from the base  12 . These posts  43  are used so that when multiple trays  10  are stacked inside one another the base  12  of a second tray placed inside of a first tray will rest upon the support posts  43  and not on the top surface  24  of the base  12 . An advantage to this design is that the trays  10  will not become wedged between one another but instead are separated from one another by the height of the support posts  43  to allow the trays  10  to be easily separated. A further advantage to these support posts  43  is that since the support post  43  is connected to the base  12  and the walls  14  in which they attach, they provide additional strength and support to the walls  14  and the joints created at their intersections. 
         [0054]    Referring to  FIG. 2  it is envisioned that the first wall  16 , second wall  18 , third wall  20  and fourth wall  22  can each include (referring to  FIG. 1 ) a window  36  on the outer surface  32  opposite the inner surface  34  of each wall. The window  36  is used so that a advertisement  42  can be placed within the window  36  so that people using the tray  10  and the people passing through the security checkpoint will be able to see the advertisement  42 . In a preferred embodiment, the window  36  can be formed on the outer surface  32  of each of the walls  14 , however, for exemplary purposes the structure of the window  36  on the third wall  20  will be described in detail with the remaining walls having the same structure. 
         [0055]    The window  36  has an inner recess  40  that is created by the outer surface  32  of the first wall and an outer cover  38  that is attached over the first wall  16  outer surface  32 . The outer cover  38  can be made of a transparent or translucent material depending on the user&#39;s needs. It is envisioned that a portion of the peripheral edge of the window  36  is either adhesively or molded into the outer surface  32  of the first wall  16 , however, an open portion  31  is allowed to remain so that an advertisement  42  can be placed in the recess  40 . Between the outer surface  32  and the outer cover  38  the inner recess  40  is formed which is sized to allow an advertisement material  42  to be placed within the inner recess  40 . The advertisement  42  can be made of a thin paper-like material or any other material such as a plastic or metal provided that it fits within the inner recess  40 . The advertisement  42  is preferably of flat configuration and has an outer surface having printing thereon with this side being positioned adjacent the outer cover  38  so that it can be seen through the transparent or translucent outer cover  38 . It is envisioned that a seal  43  can be placed above the inner recess  40  to close off the space between the outer cover  38  and the outer surface  32  to prevent the advertisement  42  from falling out of the inner recess  40 . The seal  43  can have a hinged type construction that allows the seal  43  to be selectively moved to either prevent or allow material to be removed from the inner recess  40 . The seal  43  is also envisioned to be a removable friction type material such that it can be removed when needed but does not easily fall out of the recess  40 . 
         [0056]    An advantage of the present invention is that various advertisements  42  can be easily interchanged in the windows  36  when needed because the advertisements are not permanent. 
         [0057]    In an alternative embodiment, the advertisement  42  can be permanently attached to any of the walls of the tray. It is envisioned that the advertisement  42  can be permanently attached to (referring to  FIG. 2 ) the first wall  16 , second wall  18 , third wall  20  or the fourth wall  22 . Referring to  FIG. 1 , the advertisement  42  can be permanently attached so that inadvertent removal of the advertisement can be prevented. It is envisioned that the advertisement can be silk-screened or imprinted on the outer surface of the tray. After the tray has been used, and if the advertisement  42  has been worn partially away, the tray can be disposed of and a new tray can be created having either the same advertisement or a different advertisement. 
         [0058]    An advantage to the alternative embodiment of a permanent advertisement  42  being attached to the tray is that new trays are constantly being made as the older trays are either used or worn. These trays can be of a disposable variety and can be recycled after they are no longer used. Another advantage to the alternative embodiment of the present invention is that the recycling of trays constantly provides a clean and uniform look to all checkpoint areas since the trays that are being used are in good condition. 
         [0059]      FIGS. 3 and 4  show how the first wall  16  and second wall  18  have an indentation  54  formed in each wall. First wall  16  and second wall  18  are constructed of a first section  48  which extends upward from the base  12 , a second section  50  which is substantially perpendicular to the first section  48  at a first end  49  connected to a third section  52  at a second end  51  with the third section  52  being substantially perpendicular to the second section  50  and in a parallel plane to the first section  48 . The first wall  16  and second wall  18  are made of these three sections so that the trays can be easily stacked within one another. The horizontal second section  50  and the first section  48  form the actual indentation  54  itself. 
         [0060]      FIG. 5  shows how the trays  10  are nested within one another and how the third section  52  has terminates at an upper lip  46 . The upper lip  46  of the third section  52  contacts the second section  50  of a second tray  53  when a first tray  10  and second tray  53  are placed within one another. 
         [0061]    An advantage of this nesting system is that when the trays are not being used, they can be easily be stacked for storage and used at a later time. A further advantage of the nesting system is that since the advertisements are on the outer surface of the tray the advertisements can be seen at all times thereby increasing the visibility of the advertising to potential consumers which are the people being processed through the security checkpoint. 
         [0062]    An alternative embodiment of the tray is shown in  FIG. 6 . The second embodiment is a smaller tray for items such as keys, change, cell phones, PDAs and wallets. The second embodiment  60  has a base  62  having upstanding walls  64 . The upstanding walls  64  terminate at a second part  66 , which is preferably perpendicular to the upstanding walls  64 . The second part  66  has first end  61 , which is connected to the upstanding walls  64  and extends away from the upstanding wall  64  to a second end  63  which is connected to an extension  68 . The extension  68  preferably extends toward the base  62  either partially or completely the distance to the base  62 . The extension  68  is sized to allow for a window  67  to be placed thereon. The construction of the window  67  is similar to the window  36  used in the first tray  10 , except that it is smaller in construction to fit on the second tray  60 . Referring to  FIG. 7  a top plan view of the second embodiment  60  is shown. An aperture  70  is used as a grip portion on the second part  66  to allow a user to place their fingers within these holes to securely grip the tray  60 . An identification number  69  that is unique to each tray  60  can be located on the second part  66  so that the tray  60  can later be identified as being used by a particular person. 
         [0063]    Referring to  FIG. 8 , a third embodiment  80  is shown which has the same general shape and construction as the second embodiment tray  60 . The difference in the third embodiment is that several apertures  90  are positioned on a second part  86  at each of the four corners of the tray  80 . An advantage to this design is that a user can securely grip the tray  80  using any of these apertures  90  to move the tray  80  to the desired area. It is envisioned that this third embodiment  80  can use on its side wall  81  a similar window  36  as in the first embodiment  10 , therefore, it will not be described in detail. 
         [0064]    Referring to  FIG. 10 , a system of the present invention using the trays described earlier will now be described in detail. The system of the present invention includes using of a first cart  102  at a starting point before the security point  104 , using trays  106  and  108 , and the using of a second cart  110  which is identical to the first cart  102 . As a person enters the checkpoint, they are told by security personnel to put any of their carry on baggage or electronic items, such as laptop computers, onto the conveyer belt to be processed through the x-ray machine. With the present invention, a laptop computer is placed by the person being searched into a larger tray  108 , which is sized to fit around the laptop computer so that it is not damaged as it is passing over the conveyer belt and through the x-ray machine. The person is then usually asked by security personnel to remove any loose items and bags and place them in either a smaller tray  106  or a larger tray  108  as previously described depending on the side of the items which are to be searched. A first cart  102  is placed prior to the security point where the user is then asked to remove such items. The first cart  102  is constructed so that it holds the trays  106  and  108  in a stacked position so that the empty trays can easily be taken out of the cart  102  and given to the person. After the person has put the various items into the trays  106  and  108  they are given back to the security personnel who then searches the items. The user then proceeds through the security point  104 . Typically in an airport or other area the security point will be a through the security point  104  and at a later time receive the trays  106  and  108  which they placed their items into prior to passing through the security point  104  and be told to take their items out of the trays  106  and  108  and proceed out of the security area. After the person has empted the items out of the trays, they can be placed in a second cart  110  which is identical to the first cart  102 . The empty trays  106  and  108  are stacked in a specific area of the cart  110  so that the trays can later be used again. 
         [0065]    After the second cart  110  is completely filed with empty trays  106  and  108 , the second cart  110  can be moved to the position of the first cart  102  prior to the security point  104  and provide empty trays for people going through the security point  104 . After the first cart  102  is depleted of trays  106  and  108  the first cart  102  can be moved to the location of the second cart  110  to then receive empty trays at the end of the security point  104 . The rotation of the security carts  102  and  110  and the trays  106  and  108  creates an efficient and convenient way to transport the trays from the beginning to the end of the security point  104 . 
         [0066]    It is envisioned that a third cart  103  can be used in addition to the first cart  102  and the second cart  110 . The third cart  103  can be used as a back up or spare cart with empty trays  106  and  108  contained within it to be placed in the position of the first cart  102  when needed to further speed up the process of providing trays to people going through the security checkpoint. The third cart  103  can also be used in addition to the second cart  110  as an area to place the empty trays  106  and  108  after they are used. The use of the third cart  103  further facilitates the flow of the trays  106  and  108  from the beginning to the end of the security checkpoint such as times when peak travel and passenger volume is experienced at an airport security checkpoint. 
         [0067]    Referring to  FIG. 9 , a first cart  102  will be described in detail. The first cart  102  has base  122  preferably having wheels  124  attached to the bottom surface thereon. In a preferred embodiment the base  122  has a rectangular or square shape with the wheels  124  placed at each comer of the base  122 . The base  122  has several walls  132  extending upwardly from the base  122  opposite the wheels  124 . The walls  132  in a preferred embodiment can be made of a clear plastic or a metal material such as steel for durability, however, it is envisioned that plastic or any other material that is rigid can be used. The walls  132  are spaced apart from each other to form a first tray recess  126  and a second tray recess  127 . The first tray recess  126  is used for holding the smaller trays  106  and the tray recess  127  is used for holding the larger trays  108 . Each of the recesses are constructed so that the trays  106  and  108  can be placed within the recesses so that they do not fall out of the cart  102  and can be transported. In a preferred embodiment, both tray recesses  126  and  127  have platforms  128  at the lower end thereof adjacent the base  122 . The tray platforms  128  are supported by resilient members  130  that are attached to both the base  122  and the tray platforms  128 . The resilient members  130  can be metal springs or any other resilient material such as plastic or rubber. The tray platforms  128  and the resilient members  130  are used to support the trays  106  and  108  that are placed within the tray recesses  126  and  127 . It is envisioned that in an alternative embodiment tray platform  128  may not contain resilient members of  130  and that the trays  106  and  108  themselves will rest upon the platform  128 . In a more preferred embodiment, the walls  132  of the cart  102  are divided into a first wall  134  and a second wall  136  that forms tray recess  126 . The recess creates a vertical column that allows the trays to be easily inserted into and out of the top of the cart  102  when needed thus providing a convenient and organized way of stacking the trays  106  and  108  in the cart  102 . The second wall  136  and a third wall  138  form the second tray recess  127 . The second tray recess  127  is similar to the first tray recess  126  except that the spacing between the second wall  136  and the third wall  138  is different than the spacing between the first wall  134  and second wall  136  to allow the differently sized trays to fit within the second recess  127 . 
         [0068]    The second cart  110  is an identical cart to the first cart  102 , therefore, it is not described in detail. 
         [0069]    An advantage to the present system is that the first cart  102  and second cart  110  are identical carts, thus when one cart is completely filled it can be moved to the proper location where needed. In the alternative, when one cart is completely erupted it can be moved to the appropriate area to be later filled with trays  106  and  108 . 
         [0070]    Furthermore, when there is a high volume of people being processed through the checkpoint, a third cart  103  can be used to hold the trays  106  and  108  to further speed up the movement of the trays  106  and  108  from the end point of the security checkpoint to be transported to the starting point of the security checkpoint.
