Description

TECHNICAL FIELD

[0001] The present invention relates to bookbinding machines, and in particular office document binding machines. BACKGROUND

[0002] Office binding machines employing plastic comb rings, metal comb rings, and spiral binding, and corresponding punch assemblies, are well known and used to create multi-page bound documents for a variety of purposes, such as presentation materials, instruction manuals, and corporate or project reports, to name just a few examples of the vast number of bound documents created by these types of machines. Typically, these types of machines are dedicated and used for binding purposes only, and for a specific type of comb ring or binding spine, such as the Swingline C340 Combbind binding machine.

[0003] There are some atypical machines that attempt to combine comb binding mechanisms into one machine through a complex array of punch dies, comb ring spreaders, and crimpers, using a complex array of punch dies and actuating levers, making an already complex task even more complex, such as the Akiles DuoMac-421 Heavy Duty Two-in-One Punch and Binder. Other machines are designed to use one primary binding method and the supporting mechanisms required, with the added ability for round hole punching for ring binding, one example of which is the Tamerica 213B Combination Punch and Binder. While these types of machines attempt to bring value, they employ features that are less and less used, while further compounding the situation by adding extra complexity on top of and outside of a more basic machine. As a result, office workers who are not familiar or willing to use even a basic binder will use these more complex machines even less, making them even more underutilized.

[0004] Figure 1 is a picture of a prior art multi-function binding machine, the Akiles DuoMac-421 Heavy Duty Two-in-One Punch and Binder. The supporting literature states that this machine combines two different types of binding in a single machine. The machine includes two separate punch die sets with custom configurations.

[0005] Figure 2 is a picture of a prior art multi-function binding machine, the Tamerica 213B Combination Punch and Binder. The supporting literature states that this machine is a two-in-one plastic comb ring and spiral O-shaped wire binder. The machine has 21 knockout dies, as well as a dedicated three-hole punch.

[0006] Figure 3is U.S. Patent 5,007,728 entitled "Combined Paper Punch and Binding Apparatus" to Figure 12 In the abstract section of this patent, it describes an apparatus having two punch mechanisms, operated simultaneously and driving a series of round-end punches with one mechanism and a punch plate having integral rectangular punch elements with the other mechanism, one for punching round holes in one stack of paper sheets and one for punching rectangular holes in another stack of paper sheets. In the preferred embodiment of the invention, binding instructions are provided for Douvry type plastic elastic ring binding elements operated by turning knob 24. In another embodiment given, two rows of punches of large and smaller diameter are provided in one round punch mechanism, the mechanism having a translatable bar (not shown) with holes so that one row of punches or the other row of punches is inoperative.

[0007] Figure 4 is U.S. Patent 5,187,634 entitled "Punch Selectable Punch Press" to Figure 4 In the abstract section of this patent, it describes a punch mechanism having a selector rail that changes the punch pattern by shifting, i.e., activating or deactivating, selected punches along the rail. In particular, two selected punches are activated and deactivated. In summary, by engaging and moving slidable rail 100, punches 60 and 66 will disengage while punch 64 will engage, allowing 2-hole punch to be performed. In an alternative actuation, slidable rail 100 will engage punches 60 and 66 while blocking 64, allowing 3-hole punch to be performed using a selector rod (not shown) extending through the cover and capable of being selectively operated by the user. SUMMARY

[0008] In this application, the disclosed invention "Multi-Function Document Binding Apparatus" addresses the addition of useful features within a document binding apparatus, while clarifying and thus simplifying the process when using the machine's functions, to make it inherently more operator friendly. In its simplest embodiment, it contains the mechanisms and functions required to bind documents, including a paper stack puncher and corresponding binding mechanism, aligned with the punch pattern of the main apparatus (plastic comb, wire comb, spiral comb), with the additional ability to modularly add additional functions beyond its original basic functions. In alternative embodiments, we disclose an apparatus with built-in multi-functionality that is uniquely performed in a way that encourages the operator to use it more frequently in their daily use, to familiarize themselves with the additional capabilities of the apparatus over time, including seemingly more daunting functions. In addition, we disclose some features that simplify the process of operating the apparatus as perceived by the operator (even with the extra added elements) by using conversion elements that help the operator determine in what order and at what time to operate which functions and processes to achieve a particular desired result when using the apparatus and its system.

[0009] The most common binding machines or binding apparatuses in an office environment use plastic or wire expansion combs, as well as plastic or wire spiral combs. Other forms of binding that are known include adhesive binding, thermal and non-thermal binding, and stitching binding, but these forms are not commonly used in an office environment and therefore will not be described in detail in this application, but are not excluded as possible binding methods that can be incorporated in the disclosed apparatus and system's disclosed embodiments. Less typically, some binding machines simply combine or integrate some different comb binding capabilities into one main machine as a way to add additional value to the purchaser and / or operator of the apparatus. These types of apparatuses, of which exemplary machines are shown in Figure 1

[0010] ​Furthermore, our research has confirmed that office workers who need to create presentation materials find binding machines difficult to use and unintuitive, often requiring guidance to understand the inherently complex arrangements of procedures, processes, and consumables involved in working with a particular machine. Our research further confirms that many office workers resort to other, more familiar and therefore easier methods for creating bound documents, including staples and ring binding. Based on these findings, we have strived to address these unmet needs by creating a unique binding device that incorporates these less complex binding methods within an office binding machine, thus making the machine easier to use and more familiar to operate when operators need to utilize its seemingly more complex functions when creating more complex bound documents.

[0011] We disclose an apparatus for modularly engaging and actuating or controlling devices using a master actuator, which can be manual, motorized, and / or motor-assisted. This feature allows for punching at multiple punching stations using the master actuator, which can actuate a second actuated sub-assembly upon engagement, or can actuate modularly added stations. For example, the master actuator can be used to punch a square hole for a plastic comb ring in one station and a round hole in another station, while simultaneously actuating comb ring retraction and / or comb ring unfolding actions, as well as other additional actions, at yet another station. The master lever simplifies the operator's process because, compared to the usual requirement of a lever for each task, they only need to engage the master lever for multiple tasks. When motorized, sensors or sensor arrays can be present to detect when a given task is performed by recognizing or not recognizing the element to be engaged and by corresponding communication with the user via visual or audio devices. Even though it is found advantageous to combine lever actuators into several, rather than one, main actuators with or without sub-actuators (whether automatic or semi-automatic), we disclose in this application how to actuate more than one action or multiple actions at once or sequentially when the device is reconfigured for a given purpose.

[0012] For binding devices that use plastic, wire, and spiral comb rings, it is common to include a stack punching operation that allows for the paper stack to be punched along the edge of the stack. Punch features punch out corresponding holes along this edge to accommodate the shape of the particular comb ring pattern the machine is designed for. In the embodiments presented in this invention, the device has, but is not limited to, two main document entry slots, one or both of which allow for the operation of punch dies that can be optionally integrated and interchangeable, movable, and / or selectively engageable. One of these document entry slots will allow for the setting of a particular slot for a particular purpose, such as a round hole punch for inserting documents for a simpler three-ring binder, while leaving the other available entry slot or slots for another purpose, such as a square hole punch for plastic comb binder rings. The disclosed device meets our purpose by using manual and / or automatic switching elements that allow for the operation of certain features while restricting the operation of others in an effort to guide the operator through a more sequentially relevant and compatible procedure, rather than allowing for the operation of incompatible and sequentially irrelevant and therefore more material and time wasting features due to ambiguous device operation and general procedure confusion during the binding and assembly process.

[0013] To address the aforementioned issues, when operating the round three-hole punch feature on the exemplary embodiments of the disclosed invention, the comb binding elements are covered by a cover in a lowered or down position. The lowered position allows for the operation of the three-hole punch entry slot while covering the comb binding table / features that include the comb punch entry slot in order to prevent the inadvertent square hole punch along the document edge when a round hole is desired. In an exemplary alternative, when comb binding is desired, the cover on the device will be up to allow for the operation of the square punch entry slot and plastic comb expansion table that are compatible and sequentially relevant to those processes, while preventing the operation of the incompatible round three-hole punch entry slot. Other means can be used to ensure that only compatible and sequentially relevant features are operable during a particular step, but are not limited to regulating the operability of certain related consumables by locking and unlocking the operation of those consumables depending on which step you are in the binding process or which binding method the device is set to perform. Additional other actions can be sliding engagement to allow the main lever arm to actuate one mechanical step without engaging other mechanical steps, visual indicators can also be sequentially activated mechanically or electromechanically by each previous step in order to help indicate to the device operator the next step and / or which consumable to use when. User selectable engagement and automatic and semi-automatic switching when reconfiguring the device are disclosed in this application that allow for the selective activation of multiple actions such as, but not limited to, punching, stapling, spine comb ring crimping, rotating comb ring expansion and closure, coil rotation, and sub-actions.

[0014] In further research conducted in conjunction with the use study, it was noted that alignment of punches and / or the holes they create is most difficult when attempting to use cover pages and back pages within a multi-page bound document. In this application, we disclose unique alignment mechanisms for cover pages (front and back) and pages in between those covers. This is accomplished through the use of a biased spring alignment mechanism that can move out of the way to accommodate cover and corresponding back cover spacing variations (allowing for uniform margins) when punching, then return to the default spacing after the punch is complete, which reduces operator setup errors, saves time and waste of materials. Along with this solution, we also disclose a punch alignment device that allows for visual confirmation of the setup to ensure proper alignment, whether copying a previously punched set of papers, allowing for the ability to easily add additional sheets to an existing document, or ensuring new setups are aligned to accommodate the overall document layout for a home appearance. This alignment device allows for visual confirmation, adjustment control, while ensuring precise repeatability.

[0015] We further disclose improvements in the machine and process that add additional performance and ease of use elements to improve the modular and / or integrated features in the device, and add related support accessories that enhance the appearance, functionality and output quality of the documents processed through the disclosed device.

[0016] Figure 5 is a simplified chart that summarizes some of our research findings and the objectives of the invention and how improvements to the prior art benefit the operator of the disclosed device. The chart shows various processes from left to right that create multi-page bound documents from simpler to more complex. The prior art multi-function bookbinding machine is in the innermost dotted rectangle where the majority of the unit's functionality is a comb ring and wire binding function with a limited number of combinations of two and three hole punches with binding. The invention, represented by the larger outer dotted rectangle, attempts to introduce additional features by including die cutting, rounded corners, and embossing / debossing features from the more commonly used staple feature (our research office staff use staple binding 6-7 times more often than comb ring binding) to higher levels of finishing capabilities. For these reasons, the chart shows the greater coverage that the invention has over the prior art machines while having the concept that certain additional features result in more daily interaction with the device which helps to become familiar with the device and comfortable using the device over time.

[0017] As disclosed, described and illustrated herein, the invention can be applied to various devices and machines that punch, staple, imprint, decorate and bind documents for display and should not be limited in any way by the embodiments disclosed herein.

[0051] Figure 6 represents an embodiment of the invention using modular functional additions. This illustration shows a bookbinding machine with a rotating drive shaft and an optional connecting clamp head assembly that is actuated manually using a handle, or alternatively, if the bookbinding machine is of the automatic type, by using a motorized assembly with electromechanical actuation or control means. In some embodiments, the drive shaft extends outwardly from the pivot point of the handle or other actuator. In other embodiments, the shaft extends from the body or housing of the bookbinding machine at a location other than the pivot point of the handle or other actuator. The drive shaft rotates the clamp head assembly that is connected to the mechanism of the module that is connected or interconnected and acts on that mechanism. The interlocking drive clamp allows for the addition of modules such as Figure 6 the embossing or die cutting module shown in Figure 6 the background of the same bookbinding machine where multiple modules have been added, the features and actuation of which are driven and / or controlled by the handle or motorized assembly of the bookbinding machine. In this embodiment, multiple modules are coupled to the drive shaft of the bookbinding machine. In the illustrated embodiment, the rotating drive shaft can be placed on the left or right side or both sides if maximum flexibility is required. This type of arrangement as shown would allow the base bookbinding machine to remain low cost and subsequently only modularly add the additional features required. Since these modular additions can be driven by the actuation and drive methods of the main unit, the cost of these additional modules would also be lower. Other embodiments are not excluded that should include full function modules (motorized and manual versions) that can act independently by including drive means (handle or motorized assembly) to actuate and drive their functions separately or in unison from the actuation, controller and drive methods of the main unit. In some embodiments, the additional modules can be driven by attachable handles or other actuators attached to the clamp head of the module, thereby enabling the module to be driven independently and not dependent on the base bookbinding machine and its actuators or handle.

[0052] Figure 7An alternative embodiment of the invention is shown using modular functionality additions within the host. In some embodiments, the bookbinding machine can include an accessory cavity for receiving an accessory. In some embodiments, the accessory can be a die for stamping or die cutting. The figure shows a bookbinding machine with a rotary drive mechanical assembly actuated by a handle, or by a motorized assembly of the bookbinding machine if it is an automatic type. The figure shows a container area with an optional lift lid, into which a module is added, such as a stamping or die cutting (depending on the interchangeable die inserted) module and mounted to be actuated by the same or alternative drive assembly of the host. In other embodiments, other accessories can be received and operably connected to an actuator or handle for operation of the accessory. An opening or slot in the machine housing will allow paper to be inserted and processed by the mechanical actuators of the machine. This type of arrangement as shown will allow the base bookbinding machine to be sold with or without additional features installed, and the end user will determine and add those additional features that are desired. In the alternative, this unit can be sold fully featured, including different types and shapes of additional die cutting, embossing and debossing features, to name just a few of the many possibilities. Custom shapes can be obtained additionally if desired, such as a company logo or seal. Other embodiments are not excluded, which can include a mix of integrated options that are added and / or replaceable or interchangeable within, adjacent to, or separate from the existing machine.

[0053] Figure 8 An alternative embodiment of the multi-function document binding apparatus 100 of the invention is shown using optional one or more modular and / or built-in functionality additions. This embodiment of the invention discloses a stapling assembly 700 located within the accessory cavity 702 of the binding apparatus 100. To reduce user confusion, the document binding features are inoperable when the apparatus cover 104 is in its lowered position, but the operator is allowed to operate the stapling assembly 700 and staple bar 706. In some embodiments, the stapling assembly cannot be activated for stapling when the apparatus cover 104 is in the open position.

[0054] For stapling, when the paper stack is placed within the optionally adjustable guide 704 and slid into place, the stapler lever 706 is actuated to insert appropriate staples into the paper stack. In some embodiments, the stapling assembly 700 can be activated by an actuating handle 904 to staple the paper stack. The actuating handle 904 can also be used for other operations, such as punching holes by being operably coupled to a punching mechanism. If the operator wants to complete the stapling along the entire spine of the document edge, the stapler lever 706 can be configured to slide along a repositionable guide within the cavity 702 to the next position and then be actuated to insert appropriate staples into the paper stack again. This can be done sequentially several times until the desired number of staples have been inserted along the spine of the document. Once the document is removed, a cover with a sliding attachment, snap-fit ​​attachment, or adhesive attachment can be assembled on the staples to achieve a higher level of finish even when the document is stapled.

[0055] In some embodiments, the anvil of the staple assembly 700, which shapes the underside of the staple, can be constructed to achieve a sliding attachment or snap-fit ​​attachment and fixation on the cover. Heavy-duty, higher-capacity staple assemblies can be additionally inserted, or alternatively and optionally, actuated by an actuating handle 904, due to the greater stability of the actuating handle and the greater leverage it provides to the operator. All manual staple operations can be performed by a motorized device and powered by a battery DC power supply or a plug-in AC power supply, and these types of staple mechanisms are well-known in today's market. A unique aspect disclosed is an auxiliary stapler in which the mechanical stapler is assisted by a power unit or a stored power unit or a mechanically actuated stored power unit to make the staple cycle and / or initiation feel familiar, and the added benefit is that the power assistance allows for staplering and edge binding of thicker stacks.

[0056] In embodiments that include a round hole punch function, the round hole punch slot 504 is operable because it is a simpler operation than comb ring stapling and is the next most commonly used stapling operation after stapling. After the punch actuating handle 904 is raised upward, this correspondingly rotates the actuating mechanism assembly 900, thereby ensuring that the punch die is subsequently in its retracted state (not shown), the operator then places the paper stack into the round hole punch slot 504, while holding the inserted stack in place and / or allowing the stack to rest on an optional pull-out or wire frame paper stack support assembly, the operator then proceeds to lower the punch actuating handle 904 in a downward stroke, which correspondingly rotates the actuating mechanism 900 to engage the punch die with the inserted paper stack, thereby forming the desired round shaped punch holes along the spine of the inserted paper stack. After the punch sequence is completed, the actuating handle 904 can then be raised again in sequence to release the punch die from the paper, thereby allowing the paper to retract from the punch slot 504. As an alternative to direct engagement of the punch die for handle actuation, a temporary cam driven mechanism can be used to allow insertion of paper even when the actuating handle 904 is in the lowered position, when the handle is raised, the rotating actuating mechanism 900 is rotated to subsequently engage the punch die actuator, and through the actuating handle 904 downward stroke action performed by the operator, the punch die is actuated, the paper stack is punched within the punch slot 504, and the die is retracted in the same sequential downward stroke. This punch actuation sequence uniquely allows for insertion and retraction of the paper stack when the actuating handle 904 is in the lowered position. All of the manual punch operations can be implemented by motorized means and powered by either battery DC power or plug-in AC power, and these types of punch mechanisms are well known in today's market.

[0057] Figure 9 Another alternative embodiment of the multi-function document stapling apparatus 100 of the present invention that represents an alternative embodiment that uses one or more modular and / or built-in functional additions. This particular embodiment of the present invention discloses a staple assembly 700 that is located within the accessory cavity 702 of the stapling apparatus 100 so as to easily identify the function of the mechanism because it has a similar signaling element as a commonly used desktop stapler. Similar to the staple assembly 700, the punch assembly 800 is also located within the accessory cavity 702 of the stapling apparatus 100 so as to easily identify the function of the mechanism because it has a similar signaling element as a commonly used desktop punch. Figure 8In some embodiments, when the device cover 104 is in its lowered position, the document binding features such as the puncher are inoperable, but the stapling assembly 700 and the staple gun lever 706 are allowed to be operated. When the paper stack is placed against the optionally adjustable guide rails 704 and slid into position, the staple gun lever 706 is actuated by the operator to insert the appropriate binding staples into the paper stack. If the operator wants to complete the staple binding along the entire spine of the document edge, the document is manually moved to the next position along the adjustable guide rails 704 within the mating cavity formed by the lowered device cover 104 and the upper housing member 106, and the staple gun lever 706 is again actuated to insert the appropriate binding staples into the paper stack. In some embodiments, the stapling action is actuated by the actuating handle 904. Regardless of the actuation, the stapling can be completed several times in sequence until the desired number of binding staples have been inserted along the spine of the document. A heavy duty higher capacity stapling assembly can additionally be inserted or in the alternative to the stapling assembly 700 with the larger staple gun lever 706 or the conversion lever handle, or as another alternative option, configured to be actuated by the actuating handle 904, as this handle is more robust and will give the operator more leverage.

[0058] In some embodiments, the round hole puncher slot 504 is operable as this is a simpler operation than the comb ring binding and is the next most commonly used binding operation after stapling. However, in other embodiments, only one operation is operable at any one time. The operator places the paper stack into the round hole puncher slot 504 and then proceeds to actuate the puncher handle 904 with a downward stroke to engage the machine's punching mechanism while the insert stack is held in place and / or the paper stack is resting on the optional pull-out or wire frame paper stack support assembly (now shown in the retracted or lowered state).

[0059] Figure 10 The stapling assembly 700 is shown, which includes a front loading staple refill to ensure the ability to easily install refill staples of different staple types for different document thicknesses. To refill the unit, the staple gun lever 706 is lifted upward to operate the staple cartridge holder 710. The holder 710 is designed to accommodate pre-loaded staple cartridges as well as standard staple cartridges in order to allow easy replacement of staples for specific needs and for refill purposes. The adjustable guide rails 704 (not shown) allow for adjustment of the paper position relative to the staples and are user configurable. The optionally adjustable guide rails 704 can be located on the upper housing member of the unit, allowing alignment with the majority of the document to be staple bound.

[0060] Figure 11The multi-functional document binding device 100 of the invention is shown, with the device cover 104 in a raised position. When an operator wants to enter binding mode using the disclosed device, they will reconfigure the device by first raising the device cover 104 to the raised position. When raised, the stapling assembly 700 is also in the raised position to temporarily limit its function (the stapling feature can be configured to optionally lower and / or raise away from the cover, while remaining raised when the cover is raised by using a resistance pawl or a pull or slide latch mechanism). This temporary limitation of operability of the stapling assembly 700 allows the operator to focus on the steps required to use the comb-loop binding feature, which is achieved by making other features more difficult to operate than easily or obviously operable features when the machine has been reconfigured for a specific function in its multi-functionality, and / or operablely inoperable when the machine has been manually or alternatively automatically reconfigured to an alternative user-selected mode.

[0061] For example, when the machine is in plastic comb-loop binding mode, the device cover 104 is in a raised position and configured to temporarily prevent easy operation of the round hole punch slot 504. This is done to make it easier for the operator to understand that the binding hole punch slot 602 is the main punch slot used during binding. Similarly, in some embodiments, operation of the stapler assembly 700 is also prevented. In some embodiments, the device cover 104 is placed in a raised position to prevent the stapler assembly from being activated. In other embodiments, various features are made less easily operable in order to signal or guide the operator to use the device correctly. Therefore, those skilled in the art will recognize that describing a function as “prevented” can have a range of meanings, including making the function or device less easily operable or used.

[0062] Furthermore, when the device is in binding configuration, the binding comb storage drawer 310 can be opened to access the stored binding combs. During binding, the operator raises the punch lever handle 904, which correspondingly rotates the actuation mechanism assembly 900, ensuring that the punching die of the binding punch assembly 600 is subsequently in its retracted state (not shown). The operator then inserts the paper stack into the binding hole punch slot 602, simultaneously holding the inserted stack in place and / or allowing the stack to rest on an optional pull-out or wireframe paper stack support assembly. The operator then continues to lower the punch actuation handle 904 by a downward stroke, which correspondingly rotates the actuation mechanism 900 to engage the punching die with the inserted paper stack, thereby forming the desired punch along the ridge of the inserted paper stack. After the punching sequence has been completed, the actuation handle 904 can subsequently be sequentially raised again to release the punching die from the paper, allowing the paper to retract from the binding hole punch slot 602.

[0063] As an alternative to direct engagement of the punch die to the handle actuation, an intermediate cam drive mechanism can be used to allow paper insertion even when the actuation handle 904 is in the lowered position, as the actuation handle 904 is raised, the rotating actuation mechanism 900 subsequently engages the actuator of the staple punch assembly 600 and the downward travel of the actuation handle 904, the punch die is actuated, the paper stack is punched within the staple punch die slot 602, and the die is retracted in the same sequential downward travel. This punch actuation sequence uniquely allows the paper stack to be inserted and retracted when the actuation handle 904 is in the lowered position.

[0064] All manual punch operations can be achieved by motorized means and powered by either battery DC power or plug-in AC power, and these types of punch mechanisms are well known in today's market.

[0065] To punch the cover and back cover at the proper spacing, a cover spacing guide 606 can be used to ensure that the cover and back cover are properly punched. Typically, the cover and back cover are larger in size than the pages to be stapled between them. The spacing guide 606 is designed to move outward a preset range (optionally adjustable by the operator) to change the alignment of the staple punch die slot 602 accordingly to accommodate the larger cover and back cover. As an alternative embodiment, the spacing guide can be configured to return to its default position (non-cover spacing position) after the punch cycle to ensure that the operator engages the spacing guide 606 only as needed and does not inadvertently leave it in the incorrect position and cause waste due to incorrectly punched pages.

[0066] After the cover or back cover is punched, or when the operator is ready to staple the pages with a comb ring, the plastic comb ring 320 can be inserted into the stapling assembly 300 (in this case, the comb ring dispenser assembly), (other stapling systems can include metal comb rings instead of plastic comb rings 320, and corresponding metal comb ring retainers and crimpers, document clips, and spiral binding rotators, etc.), the plastic comb ring 320 is placed behind and aligned with the comb ring retainer 302 to ensure that the comb ring is engaged with the comb ring prongs 304. The prong lever 308 is pulled toward the front of the machine, which correspondingly slides the comb ring prongs 304 toward the front of the machine, and then opens or expands the plastic comb ring 320. The operator then places the previously punched cover or back cover onto the expanded plastic comb ring 320, followed by the sequentially corresponding pages, and then the cover or back cover is the last to be inserted, depending on how the operator initiates their document stack sequence. Once the entire document has been assembled, the prong lever 308 is actuated in the opposite direction to release the plastic comb ring 320, allowing it to retract to its natural state, thereby securing all of the document pages therein.

[0067] Figure 12Improved binding comb rings are represented, specifically resilient plastic binding comb rings with unique locking features. Plastic comb rings are manufactured to resiliently return to shape, thus easily re-opening after binding, resulting in some resilient comb teeth releasing, inadvertently causing pages or portions of pages to not be held securely. We disclose a resilient plastic binding comb ring with a slot feature that adds the functionality of a locking tab to address the aforementioned issues with standard binding comb rings. The binding comb ring 322 is configured with a comb ring slot 324. The comb ring slot allows the comb ring locking tab 326 to be easily pushed through the comb ring slot 324. After being pushed through, the winged tab of the comb ring locking tab 326 is configured to prevent the comb ring locking tab 326 from being reversed out of the comb ring slot 324. Other embodiments will allow for multiple locking tab points to enable the comb ring to be adjusted to various sizes, which still allows the bound pages to easily flip and lay flat regardless of the locking tab feature. Another advantage of the comb ring slot 324 is that it enables a plastic binding comb ring that is typically easier to use and less costly to have the look and appearance of a wire-bound document.

[0068] Figure 13 is a more detailed illustration of the puncher device of the disclosed apparatus and its features. The upper housing operating panel has been removed to expose the round hole punch assembly 500. The round hole punch die assemblies 506a, 506b, and 506c are held by the assembly guide rail 502. One or more of the die assemblies can be slidably mounted to the assembly guide rail 502. For example, to move the die assembly 506c, the operator engages the die latch 510c to release the locking tab from the corresponding notch on the assembly guide rail 502, moves the die assembly 506c to the desired position, releases the die latch 510c to lock the die assembly in place. The assembly guide rail 502 can be configured with slidably actuated guide rail sections that will allow one or more of the die assemblies to be moved in unison to facilitate changes and adjustments of the dies from a two-hole punch to a three-hole punch and other viable configurations and to be able to easily return afterwards. This actuated guide rail can be adjustably modified by the operator to adjust the center-to-center alignment and range of movement of the attached die assemblies, as well as the range of movement of the guide rail itself. This movement allows the installed die assemblies to move in unison with the movement of the actuation lever, and the variable die-to-die center-to-center spacing to be related to each other for maximum adjustability and reconfigurability. The actuation lever can be configured in dual position and / or multiple positions. In one embodiment, one or more of the slidably actuated guide rail sections actuation levers will protrude through the upper support housing 112 and the corresponding cover. In another embodiment it can be positioned towards the rear where the actuation lever protrudes from the rear of the machine or anywhere for ease of operation and use.

[0069] The foregoing disclosure of specific embodiments is intended to be illustrative of the broad concept understood by the present invention.
