PRIORITY CLAIM AND CROSS REFERENCE

The present patent cooperation treaty application claims the benefit of a U.S. provisional application entitled PAPER

COLLECTION SYSTEM AND DEVICE, filed November 7, 2005, having assigned serial number 60/734,328, wherein the present application claims priority thereto and benefit thereof to the fullest extent permitted by law.

TECHNICAL FIELD

The present invention relates generally to paper collection devices and, more specifically, to a paper collection system and device for accumulating and securing waste paper, such as for subsequent shredding and/or recycling, wherein a cabinet-style housing with a self-locking door is adapted with a paper guard to prevent unauthorized "reach-in" access to sensitive papers,

wherein the swing away door mount of the paper guard and uniquely supported collection bag hangers facilitate easy access to collection bag contents, and wherein the collection bag hangers provide secure positioning for weighty materials within the housing.

BACKGROUND OF THE INVENTION

Environmental consciousness has increased over time, with improved public education regarding limitations in natural resources, and with increased visibly of the potential and actual impact of unchecked global pollution. Such awareness has led to vast recycling efforts, especially for glass, certain plastics, and for paper. Many communities have embraced individual consumer recycling programs, thereby attempting to limit the amount of waste deposited in ever-growing landfills while also enabling the reclaiming of some items, thereby conserving resources, for example, saving trees by recycling paper. Other communities have turned to massive incinerators in order to reduce vast waste piles, formerly held to decompose on land. Either option, recycling or incinerating, is a viable alternative, but each typically requires at least some sorting of waste by consumers. As a result, trash sorting receptacles have been described, in order to facilitate the collection and disposal process, wherein, for example, paper is collected separately from other recyclable and non-recyclable refuse .

In addition to pollution and conservation, another recently widespread concern related to trash, and particularly to discarded papers, is that of identity theft. Such crimes often occur following the unauthorized examination of paper garbage bearing personal data and information. As a result, large percentages of homes are now equipped with personal shredders, wherein private papers are mutilated prior to placement into recycling or other garbage bins .

Certain businesses and operations, however, have long undertaken to maintain the privacy of information reflected on discarded papers. In particular, attorneys and physicians, both charged with maintaining confidentiality, must be particularly vigilant. Governmental and military facilities, too, must undertake special precautions to ensure the continued security of classified materials. In order to assist these professionals, and others, with the routine disposal of potentially large volumes of sensitive papers, professional shredding services have been designed, wherein sensitive papers are collected on-site, and removed by bonded service providers for shredding, recycling and/or incinerating. Such services allow quick disposal, even of important papers, by placement into a dedicated waste receptacle, whereby the need for the depositor to spend the time necessary to run the materials through an office shredder is eliminated. This convenience ensures and encourages proper disposal of confidential papers, irrespective of volume.

However, security of the discarded papers within such a collection container can be a relevant concern. As such, locks have been designed; however, in view of the present invention, each is disadvantageous. That is, keyed locks are routinely utilized, wherein only authorized individuals possess the ability to open the lock, such as during collection of the bulk paper materials. Unfortunately, in order for the collection bin to be re-secured following access, such locks must be proactively re-engaged. Thus, if an individual should be interrupted during the process, or should otherwise forget, a traditional paper collection cabinet would remain unlocked, and thus unprotected.

Moreover, whether locked or unlocked, the possibility of unauthorized "reach-in" access may remain. Some presently available collection receptacles incorporate a cross bar to prevent an individual from being able to reach therein. However, because such bars are fixed within the cabinet in a position intended to block access to the waste receptacle therein, they disadvantageously continue to inhibit free access to the receptacle during the emptying process.

Further, with respect to the collection bag, the weight thereof from the collected paper can cause failure of the bag mounts, wherein repeated bag transfer, with potential pulling by the authorized collector, can result in weakening or bending of a

traditional hook or hanging rod, or can result in a disadvantageous expansion of its mounting aperture.

Therefore, it is readily apparent that there is a need for a shredding/recycling paper collection system and device, wherein a self-locking door safely protects contents while facilitating authorized access, wherein a door-mounted paper guard prevent unauthorized access to collected papers, without inhibiting access for emptying, and wherein a unique bag mounting system soundly supports the collection bag, yet facilitates safe and easy access to and replacement thereof, thus preventing the above-discussed disadvantages .

BRIEF SUMMARY OF THE INVENTION

Briefly described, in the preferred embodiment, the present invention overcomes the above-mentioned disadvantages and meets the recognized need for such a device by providing a paper collection system and device for receiving and securing waste papers for subsequent shredding, recycling, or the like, wherein a cabinet-style housing with a self-locking door is adapted with a paper guard member to prevent unauthorized reach-in access, without inhibiting authorized access to collection bag contents, and wherein uniquely supported collection bag hangers also facilitate easy access to collection bag contents, while also

providing secure positioning for weighty materials within the housing.

According to its major aspects and broadly stated, the present invention is a generally rectangular cabinet with a flexible collection vessel removably positioned therein, wherein the collection vessel is held in position via a system of reinforced support components, wherein access to the cabinet is continuously and automatically limited via a self-locking closure mechanism and a door-mounted structural access guard.

More specifically, the present invention is a paper collection system and device, wherein a generally rectangular cabinet includes a hinged front access panel with a self-locking mechanism to prevent unauthorized access to sensitive paper documents prior to destruction of same. The self-locking mechanism necessitates use of a key, or other type of controlled access mechanism, in order to open the cabinet door. Subsequently, however, the lock remains in a ready state after opening. That is, reengagement of the lock via the key is unnecessary to secure the cabinet, because closure of the door automatically reactivates the lock, consistently preventing reopening of the cabinet in the absence of the key.

The cabinet door also includes a deposit way, in the form of a generally rectangular-shaped opening proximate the upper edge of

the door, through which documents and other papers are deposited for collection. A document, or paper guard for inhibiting reach-in access into the collection compartment is provided on the interior surface of the cabinet door, just below the deposit way, wherein the surface of the document guard is angled down and out, extending partially over a removable paper collection vessel.

The collection vessel is a reusable bag, generally defining an elongated parallelepiped shape in order to adaptively fit and fill the cabinet. The bag includes hanger ports, opposingly positioned in pairs, proximate the upper edge of the bag, and handles extending from the base in order to facilitate removal from the cabinet when full.

Preferably, the interior sidewalls of the cabinet are adapted to support the bag via the hanger ports, wherein specialized support hooks are mounted inside the cabinet walls. The hooks are operatively designed to effectively support the heavy weight of a collection bag full of discarded paper, wherein placement of the hook mount is positioned to enable the transfer of a portion of the force from the weight of the bag away from the hook to the cabinet itself, transferring the force generated by the momentum of the weight toward the cabinet wall, thereby avoiding undesirable bending or failure of the hook. Via a fulcrum-like action, the downward gravitational pull of the bag contents coincidentally serves to further insert the hook mount into the cabinet wall,

unlike previously described mounts. Another support mechanism is alternately envisioned, wherein the reusable collection bag is adapted with male bracket members and is slidably hung thereby via rails or troughs mounted or otherwise defined within the cabinet interior.

Therefore, a feature and advantage of the present invention is the ability of such a system and device to facilitate and encourage the collection of waste paper, for shredding, recycling, or other disposal.

Another feature and advantage of the present invention is the ability of such a system and device to direct paper feed.

Another feature and advantage of the present invention is the ability of such a system and device to prevent unauthorized reach- in access via a protective document guard, yet to also facilitate authorized access to collection bag contents by mounting the guard in a swing-away manner to enable entirely unimpeded retrieval of the collection bag.

Yet another feature and advantage of the present invention is the ability of such a system and device to provide secure positioning for weighty materials within a protected housing.

Still another feature and advantage of the present invention is the ability of such a system and device to maintain the privacy of information reflected on discarded papers.

Still yet another feature and advantage of the present invention is the ability of such a system and device to ensure and encourage proper disposal of confidential papers, essentially irrespective of volume.

Still another feature and advantage of the present invention is the ability of such a system and device to self-lock, thereby safely protecting contents while facilitating authorized access.

Yet still another feature and advantage of the present invention is the ability of such a system and device to inhibit unauthorized reach-in access, thereby safely protecting contents while facilitating authorized access.

Yet still another feature and advantage of the present invention is the ability of such a system and device to continuously and automatically limit access to contents.

These and other objects, features and advantages of the invention will become more apparent to one skilled in the art from the following description and claims when read in light of the accompanying drawings .

Preferably, strikeplate 33 is securely mounted to cabinet sidewall 21 such that latchbolt 35 engages therewith upon closure of door 30, preventing subsequent opening thereof without use of a key.

Although spring bolt rim lock 36 is preferred, other types of self-locking mechanisms 34 could be utilized in order to accomplish the desired feature of consistently preventing reopening of the cabinet in the absence of the key by eliminate the need for proactive locking following authorized access.

Further, although keyhole 38 is preferred for controlling access via a key, other types of access controls could be utilized, such as a mechanical and/or electronic keypad or remote. Further, cabinet 30 could also and/or alternately include an alarm mechanism to indicate a reminder signal to an authorized user that hinged panel 30 remains unsecured. In such case, hinged panel 30 could be adapted to require proactive locking following authorized access thereto.

Preferably, door 30 includes deposit way 40, preferably generally rectangular-shaped opening 41 proximate upper edge 42 of door 30, preferably defined with generally rounded interior corners

44 through which documents and other papers are safely deposited

for collection. Preferably, document guard 50 is provided proximate deposit way 40 for facilitating proper directional feeding of papers into collection bag 100, wherein document guard 50 is preferably affixed on interior surface 46 of cabinet door 30, just below deposit way 40.

Referring now to FIGS. 6A-6D, document guard 50 preferably defines a generally triangular profile, wherein upper surface 52 is preferably angled down from attachment wall 54 to end wall 56, and wherein upper surface 52 is preferably smooth, thereby facilitating movement of papers there along, exiting into collection bag 100 proximate end wall 56, while functionally blocking reach-in access, via deposit way 40, into collection bag 100.

Also alternately, plurality of collection bag hangers 70 could be configured as depicted in FIG. 5C, wherein attachment base 82 could extend from support arc 80. Inner sidewalls 22a and 22b of cabinet housing 20 could be adapted with receiving ports 84 therefore, thereby further transferring pulling forces from collection bag 100 to cabinet housing 20, and further inhibiting and/or preventing downward and/or outward movement of attachment head 74 from hanger port 102. Also similarly, yet again alternately, plurality of collection bag hangers 70 could be configured as depicted in FIG. 5D, wherein reinforcement member 86 could extend from support arc 80, providing additional strength at the force transfer/bearing point along support arc 80. One skilled in the art would readily recognize that reinforcement member 86 and/or attachment base 82 could extend from preferred U-shaped support hanger 70.

Referring now to FIGS. 5E-5F, plurality of collection bag hangers 70 could be retained within plurality of installation ports 90, wherein plurality of collection bag hangers 70, as depicted in FIG. 5C, wherein each attachment base 82 could extend from support arc 80 and could be supported by plurality of installation ports 90. Each installation port 90 could be defined within inner

sidewalls 22a and 22b of cabinet housing 20, wherein plug 94 could be inserted therein. Plug 94 could be formed from plastic, metal, or other suitable material, and could define a general circular diameter with central receiving port 95 and ring support 93 defined therein. As each collection bag hanger 70 is screwed into cabinet housing 20 at central receiving port 95, attachment base 82 could rotate within ring support 93, wherein upper region 91 of ring support 93 facilitates passage of attachment base 82, and wherein lower region 92 of ring support 93 effectively defines receiving port 84 for final reception of attachment base 82 in a manner capable of providing easy installation and strengthened support for collection bag 100, via the extended diameter of plug 94, while avoiding failure of collection bag hangers 70. It is noted that a similar configuration could also be utilized without plug 94, wherein installation port 90 could receive a collection bag hanger 70 directly therein.

In the preferred configuration, receiving ports 84 are defined in sidewalls 22a and 22b of cabinet housing 20 in an angular fashion, wherein rear receiving ports 85a are defined closer to top edge 41 of cabinet housing 20 than front receiving ports 85b, thereby defining an angle therebetween that is opposing to the preferred downward angle defined by document guard 50. Secure mounting of plurality of collection bag hangers 70 within front and rear receiving ports 85b and .85a, respectively, thus enables collection bag 100 to be presented toward deposit way 40 for ease

of filling. While such configuration and the benefits attendant thereto are recognized, it is recognized that collection bag 100 could be hung in an essentially level formation, or even opposingly angled, although collection of papers could be effected thereby.

In an alternate embodiment, paper collection system and device 10 could comprise an alternately configured collection bag support system (not shown) , wherein generally horizontally- positioned support rails could be mounted along inner sidewalls 22a and .22b of cabinet housing 20, or troughs or elongated wells could be defined within inner sidewalls 22a and 22b to slidably retain and support the collection bag therein. For such an embodiment, the collection bag, proximate reinforced upper edge 106, could be adapted with a pair of opposingly positioned bracket-like members, with a male-type configuration, wherein the male bracket members could be sewn, glued, or otherwise supportively held by the collection bag ^' in a manner capable of bearing the weight of a full load of discarded paper. The male bracket members could define an extending, sturdy arm member positioned essentially parallel with the upper edge of the collection bag, wherein the arm member could defines an "L" or "T" shaped cross-section, and each support rail or trough within the cabinet housing could define a female well with a compatible cross-section in order to enable slidable reception of the bag brackets and support thereof.
