Description:
BACKGROUND 
     The present invention is generally directed to shredders and, more specifically, to a shredder having a pivotable top panel with an integrated display. 
     Conventional shredders can have one or more slots designated for the insertion of material to be shredded, and the action of the shredder is determined by the user&#39;s selection of one of three operating modes. The first operating mode is an “off” mode in which the shredder blades are deactivated and no shredding of material can take place. Material placed in the shredder slot may come in close proximity to the shredder blades but the material will not by itself activate the shredder. The second operating mode is an “on” mode in which the shredder blades continually rotate to shred any material inserted into the shredder. The third operating mode is an “automatic” mode in which the shredder blades are automatically activated when the shredder detects that material is being inserted into the shredder. The “automatic” mode is advantageous in that material can be sporadically shredded without having to continually turn the shredder on and off. This makes it easy to open mail and immediately shred those items which are unneeded and may contain personal information. 
     However, the use of shredders in “automatic” mode can be problematic. The user can unintentionally leave the shredder in “automatic” mode after all shredding tasks are completed. The lack of noise generated from shredder blade movement and the difficulty of visually determining the shredder state by observing the selectable control or interpreting a visual indicator may lead the original user or a new user to believe that the shredder is in the “off” mode. The original user or a new user who is unaware that the shredder is waiting to detect the insertion of material may position fingers or clothing near or inside the uncovered shredder slot, which may lead to serious injury. 
     Safety hazards are also present in those shredders operating in “on” mode, as a user may leave the shredder in “on” mode while unattended. A user who is interrupted by another task may leave the shredder on when leaving the work area, or a user with hearing impairment or in a noisy environment may be unaware the shredder is still in the “on” mode. If the noise from the running blades is not sufficient to alert the original user or a new user to the shredder state, it may be difficult to visually determine the shredder state. 
     A general safety hazard with a conventional shredder is the ability of any person to activate the shredder blades. The danger is greater when the shredder is in a home environment where a young child may approach an unmonitored shredder. The location of the shredder controls may allow a young child to place the shredder into the “automatic” or “on” mode and insert material into the shredder while risking serious injury. 
     It may be advantageous to provide a shredder that includes a pivotable top panel with an integrated display that may alert a user to the current state of the shredder, and that may allow the a user to securely cover the shredder slot in a way that protects the display and provides increased safety for others who come into contact with the shredder.

The term “activated state”, as used with selectable control, means that the selectable control has been manipulated so that the selectable control is set for a particular function. For example, if the selectable control is a simple switch, then the activated state may be having the switch turned to another position and if the selectable control is a touch sensor, then the activated state may be initiated by depressing or touching the sensor in a predetermined manner. The term “display”, as used in the claims and in corresponding portions of the specification, means “any one of a liquid crystal display, a plasma display, or any other suitable display mechanism.” The term “biometric information”, as used in the claims and in the corresponding portions of the specification, means “any biometric information including, but not limited to fingerprint scanning, palm scanning, voice recognition, facial recognition, retinal scanning, and the like.” The language “at least one of ‘A’, ‘B’, and ‘C’,” as used in the claims and in corresponding portions of the specification, means “any group having at least one ‘A’; or any group having at least one ‘B’; or any group having at least one ‘C’;—and does require that a group have at least one of each of ‘A’, ‘B’, and ‘C’.” Additionally, the words “a” and “one” are defined as including one or more of the referenced item unless specifically stated otherwise. The terminology includes the words above specifically mentioned, derivatives thereof, and words of similar import. 
     Referring to  FIGS. 1-13 , wherein like numerals indicate like elements throughout, there is shown a preferred embodiment of a shredder  10  according to the present invention. Briefly speaking, the shredder  10  includes a top panel  22  that has a display  24  integrated therein. The integration of the display  24  allows superior shredder control options that are easier for users to operate. The display  24  also makes monitoring of shredder operations simpler. Additional features (such as biometric controls, remote locks, automatic shutdown, and touch screen controls) may be integrated with the top panel  22  to provide a shredder that has even more efficient functionality and versatility. The preferable integration of the display  24  with the top panel  22  also allows for the shredder to have a modern flush look that is sleekly styled when the top panel is in the closed position (as shown in  FIG. 1 ). Applicants discovered that another advantage of preferably integrating the display  24  with the top panel is the increased ease of replacement of the display by merely changing the top panel  22 . Applicants also discovered that an advantage of preferably having the display  24  hidden when the top panel  22  is closed is that it reduces the attraction of the shredder to young children and babies. This further increases the safety of the shredder  10  of the present invention. 
     The shredder  10  of the present invention is preferably constructed of a polymer for maximum rigidity. However, the shredder can be constructed of any suitable material without departing from the scope of the present invention. 
     The shredder  10  preferably receives power from an outlet via a power conduit  38 , such as an electrical cord. However, the shredder  10  can be powered by batteries or by any other suitable power source without departing from the scope of the present invention. 
     Referring to  FIGS. 1 and 2 , the shredder  10  includes a shredder head  12  and a shredder housing  16 . While the preferred shredder  10  has a generally rectilinear shape with a level top surface  56  and an arcuate member comprising the front surface  48 , those of ordinary skill in the art will appreciate from this disclosure that the shredder  10  can have any shape without departing from the scope of the present invention. 
     The shredder head  12  includes a major surface  14  defining a slot  34  adapted to receive material to be shredded, and at least one selectable control  36  is preferably located on the major surface  14 . A top panel  22  may be located on the major surface  14  of the shredder head  12 , and may be attached to the shredder head  12  at a pivot  26 . Alternatively, the top panel can be connected via a hinge (not shown), gearing, or any other suitable connection means. 
     The top panel preferably includes a display  24 . The display is preferably, but not necessarily located generally centrally on the top panel  24  and may be configured to be hidden from view when the top panel  22  is closed. The pivot  26  or other connection mechanism enables the top panel  22  to move between a first, closed position and a second, open position. In the first, closed position, the top panel  24  covers the slot  34  and possibly the at least one selectable control  36 . A front panel  42  preferably comprises the majority of the front surface  48  of the shredder housing  16 , and pivots along a generally vertical axis  68  to allow access to the shredder basket  18  which is seated in the interior of the shredder housing  16 . The generally vertical axis is preferably defined by the hinge connecting the front panel  42  to the shredder housing. Referring to  FIG. 5 , those of ordinary skill in the art will appreciate from this disclosure that the term “generally vertical axis  68 ”, as used in the claims and in the corresponding portions of the specification, means “extending generally upwardly from the shredder base to form an angle  70  with a plane  72  defined by the shredder base of at least forty five (45) degrees”. 
     Referring to  FIG. 1 , one embodiment of the present invention preferably includes a shredder  10  with a shredder head  12  and shredder housing  16 . The top panel  22  is shown in its first, closed position, and the top panel is preferably positioned in a recess  30  defined by the major surface  14  of the shredder head  12 . While the top panel  22  is in its first, closed position, the display  24  is preferably not viewable, and the top panel  22  is preferably positioned to cover the slot  36  and protect the display  24 . Not only does the top panel  22  protect the display  24  by covering it, but it also reduces any attractive nuisance that may be created for small children due to the reflectivity of the display  24 . 
     The top panel  22  preferably extends to the lateral sides of the shredder head  12  to form a portion of the lateral surfaces  52 ,  54  of the shredder. The exposed surface of the top panel  22  is preferably flush with the non-recessed portion of the major surface  14  of the shredder head  12 , such that in this configuration the shredder  10  has an aesthetically pleasing appearance. The front side  48  of the shredder  10  is preferably formed by an arcuate member which is shared by the shredder head  12  and the front panel  42  of the shredder housing  16 , and which forms a smooth and aesthetically pleasing front surface  48 . In its first, closed position the forward edge of the top panel  22  forms a parallel arc which complements the shape of the front surface  48  of the shredder  10 . 
     Referring to  FIG. 2 , the top panel  22  is shown in its second, open position, in which the display  24  is visible to the user and can provide visual information to the user. In this configuration, the slot  36  is exposed, and the user can access the at least one selectable control  38  to put the shredder  10  into an operational mode. The shredder has at least one operational mode, which may consist of one or more of an “automatic” mode and an “on” mode. In the “automatic” mode, a sensor in the slot  36  is activated to detect material placed into the slot. When material is placed into the slot  36  a controller activates the shredder blades  40 , which shred the material. In the “on” mode, the shredder blades  40  continuously operate to shred any material inserted into the slot. In either mode, the shredder  10  preferably returns to the “off” mode when the top panel  22  is moved from its second, open position to its first, closed position. 
     The display  24  is preferably comprises a liquid crystal display with sufficient illumination to be visible in a low lighting situation. However any other suitable display such as a plasma display or an organic light emitting diode display can be used, and the display can incorporate any type of illumination without departing from the scope of the present invention. Furthermore the display  24  may include touch screen controls to allow the elimination of separate controls from the shredder if desired. During normal operation of the shredder, the display  24  may provide information regarding the current operating mode, including if the shredder state is adapted to shred a particular class of material. 
     The display  24  may include a touch screen which can incorporate a biometric sensor and/or other selectable controls therein. For example, the display may include alphanumeric touch screen icons to allow the activation of the shredder to require entry of a particular code or biometric information. Similarly, the shredder housing may include a lock to prevent the front panel from being opened unless a code is entered via the display  24  or other selectable control. To increase security and to prevent children from playing in the shredded material, the shredder  10  may require that a code or biometric information be entered via the display  24  prior to disengaging the front panel to allow opening thereof. 
     The display  24  may also provide warnings when an excessive amount of material inserted into the slot  36 , or when maintenance of the shredder  10  is required, such as lubrication of the shredder blades  40 . In a situation when the shredder  10  is left in an activated mode without material being inserted into the slot  36 , the display may alert the user to an impending automatic shutoff. That is, when the shredder  10  detects that the top panel  22  is in the second, open position and that material has not been inserted into the slot for a predetermined period of time, then the shredder may automatically move the top panel  22  into the first, closed position and/or deactivate the shredder blades  40 . The predetermined period of time is preferably three minutes, but can vary as desired without departing from the scope of the present invention. Furthermore, the selectable controls may allow a user to vary the predetermined period of time prior to shredder blade deactivation and top panel closure to any desired time. The rotation of the top panel  22  may be accomplished using gearing, a linkage arrangement, solenoids, or any other suitable closing and/or opening mechanism. 
     For example, in one embodiment of the current invention the shredder  10  includes a timer control as one of a plurality of selectable controls  36 . The timer control is adapted to allow a user to set the duration of time that the shredder will remain in “automatic” or “on” mode. The display  24  visually informs the user of the time remaining, and at the expiration of the timer the shredder returns to the “off” mode. The timer control may also be configured to automatically return the top panel  22  to its first, closed position after the completion of the set time. 
     In another embodiment of the present invention, a securing mechanism  30  is adapted to prevent the top panel from moving from the first, closed position to the second, open position. The control  32  for the securing mechanism  30  may take the form of a key lock, combination lock, switch, or any other suitable securing device. For example, the control  32  may be a biometric sensor without departing from the scope of the present invention. One non limiting example of a suitable biometric sensor is the MBF Solid State Fingerprint Sensor manufactured by Fujitsu. Details regarding one possible construction of a fingerprint sensor is set forth in U.S. Pat. No. 7,235,853, entitled “Fingerprint Detection Device and Method of its Manufacture, and Apparatus for Forming a Protective Film”, which issued on Jun. 26, 2007, and which is hereby incorporated by reference in its entirety as if fully set forth herein. While two examples of biometric sensors have been mentioned, those of ordinary skill in the art will appreciate that any suitable biometric sensor can be used with the shredder  10  of the present invention without departing from the scope of the present invention. For example, the biometric sensor can be configured for fingerprint recognition, palm recognition, voice recognition, facial recognition, retinal scanning, temperature recognition, or for detection of any suitable biometric parameter. The biometric sensor is in communication with the shredder  10  and is adapted to detect predetermined biometric information. When activated, the biometric sensor preferably causes the top panel  22  to automatically move from the first, closed position to the second, open position and activates the plurality of shredder blades  40 . The biometric sensor can be configured to accept predetermined biometric information that includes multiple users or a single user without departing from the scope of the present invention. Alternatively, the biometric sensor may be configured to activate the shredder blades. Those of ordinary skill in the art will appreciate from this disclosure If that biometric sensor can be integrated with the display  24  without departing from the scope of the present invention. Similar controls may be used to secure the front panel of the shredder housing without departing from the scope of the present invention. 
     In another embodiment of the present invention, the securing mechanism  30  is a lock which must be disengaged prior to moving the top panel. The control for the securing mechanism  32  allows the user to disengage the lock, and after disengaging the lock the user can rotate the top panel from the first, closed position to the second, open position and activate the shredder using the at least one selectable control  38 . 
     In another embodiment of the present invention, a selectable control  32  is positioned on the shredder head  12  such that it can be accessed when the top panel  22  is in its first, closed position. When activated, the control  30  causes the top panel  22  to automatically move from its first, closed position to its second, open position. When the top panel  22  is in its second, open position, the control  30  causes the top panel  22  to automatically move from its second, open position to its first, closed position. The movement of the top panel  22  to its first, closed position preferably causes the plurality of shredder blades  40  to be automatically deactivated. The movement from the first, closed position to the second, open position can be activated by voice command when at least one selectable control  36  is configured to recognize a particular command from a user. 
     In another embodiment of the present invention, when the top panel  22  is in its first, closed position, the shredder  10  is in its “off” mode. If the user moves the top panel  22  from the first, closed position to its second, open position, the shredder  10  is put into the “automatic” mode. In the “automatic” mode, a sensor in the slot  36  is activated to detect material placed into the slot. When material is placed into the slot  36  a controller activates the shredder blades  40 , which shred the material. The shredder  10  returns to the “off” mode when the top panel  22  is moved from its second, open position to its first, closed position. 
     Referring to  FIG. 3 , the shredder display  24  is preferably clearly visible from the front of the shredder  10  to allow a user to generally operate the shredder  10  from the front side of the shredder  10  with full view of the display  24 . The majority of the front surface  48  of the shredder housing  16  comprises a movable front panel  42 . The front panel  42  is shown in its closed position, in which access to the shredder basket  18  is prevented. Wheels  20  located on the bottom surface  58  of the shredder housing  16  allow the shredder to be rolled into its desired location. The wheels  20  are preferably casters which enable maximum maneuverability of the shredder  10 . 
     Referring to  FIG. 4 , the shredder  10  of  FIG. 1  is shown in rear view with the top panel  22  in its second, open position. The display  24  is preferably not viewable in this view. The power conduit  38  is preferably attached to the back side  50  of the shredder  10 .
