Description:
RELATED APPLICATIONS 
     The present invention was first described in and claims the benefit of U.S. Provisional Application No. 61/210,424 filed Mar. 19, 2009, the entire disclosures of which are incorporated herein by reference. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates generally to staple guns, and in particular, to a device adapted for the quick, ergonomic, and automatically spaced placement of staples into a floor surface. 
     BACKGROUND OF THE INVENTION 
     Staples are utilized in a variety of applications, from common residential and commercial settings to a variety of larger versions suited for construction applications including roofing felt, installing underlayment, carpet padding, carpeting vapor barrier, building wrap, and the like. Many variations exist which are adapted for use in such construction applications and other large projects where the repeated and forceful placement of staples is required. While such devices incorporate features such as increased torque, pneumatic and electrically operated driving mechanisms, improved gripping means, and the like, the stress and strain of repeated operation of the staplers is taxing on both the equipment and the operator. 
     Various attempts have been made to provide staple guns. Examples of these attempts can be seen by reference to several U.S. patents. U.S. Pat. No. 5,165,587, issued in the name of Marks, describes a spring-actuated manual staple gun. 
     U.S. Pat. No. 4,284,223, issued in the name of Salcido et al., describes a pneumatic stapling gun adapted for easily stapling materials to a ceiling surface. 
     While these devices fulfill their respective, particular objectives, each of these references suffer from one (1) or more of the aforementioned disadvantages. Many such devices are strenuous on a user during repeated use over an extended period of time. Also, many such devices still allow for a great deal of operator error during placement. Furthermore, many such devices are not particularly adapted for use in stapling material in place on common ground surfaces. Accordingly, there exists a need for a staple gun without the disadvantages as described above. The development of the present invention substantially departs from the conventional solutions and in doing so fulfills this need. 
     SUMMARY OF THE INVENTION 
     In view of the foregoing references, the inventor recognized the aforementioned inherent problems and observed that there is a need for a staple gun which allows a user to quickly and evenly place staples along a ground surface in a manner which is accurate and comfortable. Thus, the object of the present invention is to solve the aforementioned disadvantages and provide for this need. 
     To achieve the above objectives, it is an object of the present invention to comprise a rolling staple gun which provides a means to apply staples in to a ground surface in an automatic and intervallic manner. The apparatus comprises a handle assembly, a housing, and a battery charger base. 
     Another object of the present invention is to provide easy maneuvering of the apparatus across a workspace via the handle assembly. The handle assembly comprises three telescoping handle sections which provide a conventional length adjustment means. The handle sections extend upward at an angle and comprise an ergonomic handle at a distal end in order to provide a comfortable pushing means to a user. 
     Yet still another object of the present invention is to allow a user to easily actuate the stapler via a trigger located on the handle. 
     Yet still another object of the present invention is to provide power to the apparatus via a plug-in rechargeable battery which is recharged using the battery charger base, similar to conventional power tools and the like. The battery charger base provides easy recharging via a conventional wall outlet. 
     Yet still another object of the present invention is to provide a protective mounting and enclosing means to the electro-mechanical components of the apparatus via the housing. The housing contains the components which drive staples into a subjacent ground surface. 
     Yet still another object of the present invention is to further comprise the housing of ergonomic and protective features such as an access panel, a potentiometer, wheels, and a front bumper. 
     Yet still another object of the present invention is to provide automatic stapling capabilities via a staple feeding assembly and a staple driving assembly located in the housing. The staple feeding assembly comprises conventional features such as rails, a slider, a coiled spring, and a size capable of storing a sufficient number of staples so as to minimize interruption of a project to replenish the staples. 
     Yet still another object of the present invention is to provide automatic stapling via the staple driving assembly, which comprises a control module, a pitch selection potentiometer, an encoder, a battery socket, and a solenoid actuator. The potentiometer provides a means of selectively setting the distance that the apparatus travels between stapling actions, with the distance measured via a rotary encoder affixed to an axle portion of one of the wheels. The trigger, potentiometer, and encoder provide signals to the control module which provides electronic activation of the solenoid actuator in order to drive staples in an equally-spaced linear pattern. 
     Yet still another object of the present invention is to provide quick and repeatable stapling actions via a piston and shaft assembly which comprises a spring and an inverting jack mechanism. The solenoid actuator comprises a common linear electro-magnetic device which initiates a horizontal movement of a portion of the jack mechanism, which is translated into downward motioning of a vertical portion of the jack mechanism. The spring returns the mechanism to its initial state between motions. 
     Yet still another object of the present invention is to provide a method of utilizing the device that provides a unique means of loading a desired size of staples into the apparatus via the access panel, selecting a desired distance between successive stapling actions via the potentiometer, providing easy and accurate motion of the apparatus via the handle assembly and wheels, and providing selective actuating of the stapling driving assembly via the provided trigger. 
     Further objects and advantages of the present invention will become apparent from a consideration of the drawings and ensuing description.

     The rail  102 , slider  104 , and spring housing  108  comprise particular width and height dimensions which correspond to standard styles and sizes of industrial staples  150 ; therefore, it is understood that the apparatus  10  is to be introduced in a plurality of models being specifically configured based upon said purchased staples  150  or groups of staple sizes, and as such should not be interpreted as a limiting factor of the apparatus  10 . 
     Referring now to  FIG. 4 , a section view of the apparatus  10  taken along section line B-B (see  FIG. 3 ), according to a preferred embodiment of the present invention, is disclosed. The apparatus  10  comprises internal components necessary to drive staples  150  in an accurate and controlled manner including a control module  50 , a pitch selection potentiometer  52 , an encoder  54 , a battery socket  58 , a solenoid actuator  62 , a staple driving assembly  70 , and a staple feed assembly  100 . The apparatus  10  provides a means to drive staples  150  at a user selected distance therebetween along a working surface  160 . A distance between said staples  150  is set by a user by rotating the pitch selection potentiometer  52  to a desired setting (see  FIG. 2 ). Additionally, a distance that the apparatus  10  travels across said work surface  160  is continuously measured via a rotary encoder  54  affixed to an axle portion  27  of one (1) of the rear wheels  26 . Input signals therefrom said pitch selection potentiometer  52  and encoder  54 , along with an activation signal from the aforementioned trigger  55 , are conducted to the control module  50  via internal wiring  60  which in turn provides accurate electronic activation of the solenoid actuator  62  to drive the staples  150  in an equally-spaced linear pattern (see  FIG. 5 ). The control module  50  comprises a standard plastic enclosure containing necessary electrical and electronic equipment necessary to operate the staple driving function of the apparatus  10  such as, but not limited to: circuit boards, microprocessors, input/output (I/O) signal processing components, embedded software, relays, and the like.

     The apparatus  10  also comprises a front wheel  40  which works in conjunction therewith the aforementioned rear wheels  26  to provide a three (3) point support means to the apparatus  10 , thereby providing smooth stable motioning during application of staples  150 . The front wheel  40  comprises a common cylindrical plastic or rubber member having a central horizontally extending metal axle and supportive molded-in bearings  44  being arranged at opposing side positions and being integrally-molded into a floor portion of the housing  20  (see  FIG. 3 ). 
     Referring now to  FIG. 5 , another section view of the staple driving assembly portion  70  of the apparatus  10  taken along section line C-C (see  FIG. 3 ), according to a preferred embodiment of the present invention, is disclosed. The staple driving assembly  70  comprises a solenoid actuator  62 , a first tool  72 , a second tool  74 , a driver frame  75 , a spring return mechanism  77 , and a staple aperture  80 . The solenoid  62  comprises a common linear electro-magnetic device comprising common mounting ears  63  and affixed to an underside surface of the housing  20  using common fasteners  155 . The solenoid  62  further comprises a central driving piston/shaft  64  which upon receiving a momentary flow of current from the control module  50 , propels the solenoid piston/shaft  64  and the threadingly attached first tool  72  forward in a horizontal direction. It is further envisioned that the piston/shaft  64  of the solenoid  62  provides a spring-return function. 
     The first tool  72  is guided along a horizontal plane via a bearing block  73  which slidingly contacts a top surface of the first tool  72  in a parallel manner, thereby absorbing torsional forces acting upon said first tool  72  during the staple driving process. Said bearing block is attached to an underside surface of the housing  20  using common fasteners  155 . Said first tool  72  comprises an angular forward face which engages a similarly angled upper face portion of the second tool  74  being positioned at a right angle to said first tool  72 . The second tool  74  is guided and restrained in a vertical orientation via the driver frame  75 . The driver frame  75  provides a rugged platform to anchor and guide the second tool  74  and is also attached to the floor portion of the housing  20  using common fasteners  155 . The sliding engagement of the angular faces of the first  72  and second  74  tools acts as a pair of sliding incline planes forming a simple inverted jacking mechanism to convert the horizontal force of the first tool  72  into a vertical force which acts upon the second tool  74 , thereby propelling the second tool  74  downward. Said second tool  74  in turn drives a single staple  150  downwardly through the staple aperture  80  and into the work surface  160 . The staple aperture  80  comprises a rectangular vertical opening through the bottom panel portion of the housing  20  being correspondingly sized with regards to the staple  150  so as to guide said staple  150  into said work surface  160 . The driver frame  75  provides a spring return means to automatically return the second tool  74  to the upward “ready” position via a compression spring  77  which acts upon an integral collar portion  78  of the second tool  74 . 
     However, it is understood that the apparatus  10  is not limited to the particular staple driving mechanism illustrated here and that various other simple mechanisms may be designed which provide equal functionality and as such should not be interpreted as a limiting factor of the apparatus  10 .
