STAPLE GUN SYSTEM

A staple gun system designed for efficiency in use, whereby a large number of staples are available to be dispensed from a cartridge mounted above the staple assembly during a single duration.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to the field of staple guns and more specifically relates to a staple gun system.

2. Description of Related Art

A staple gun or powered stapler is a hand-held machine used to drive heavy metal staples into wood, plastic, or masonry. Staple guns are used for many different applications and to affix a variety of materials, including insulation, house wrap, roofing, wiring, carpeting, upholstery, and hobby and craft materials.

Some staple guns have a long nose that allows the staples to be applied into recessed corners. Another special feature may be wire guides for wiring to ensure that the staples will not pierce the wire. The “forward action” staple gun has a handle that points toward the trigger end, in the opposite direction of the traditional staple gun. These tools are easier to squeeze and better place pressure at the front of the tool where the staple is ejected.

A hammer tacker is a device somewhat similar to a staple gun, except that the mechanical energy from the user's muscles is stored, as with a hammer, as momentum of the gun itself, rather than as compression of an internal spring. This type of stapler is typically used for insulation, roofing and carpeting. For most purposes square end staples are used; but some staplers can take rounded end staples for holding cables against a surface. Conventional staple guns do not hold many staples and thus must be refilled at many increments during their use. This leads to inefficiency in work project that is not desirable.

Several attempts have been made to solve the above-mentioned problems such as those found in U.S. Patent and U.S. Publication numbers: U.S. Pat. No. 2,298,123 to George H Harred; JP200207947 to Masaya Miyazaki; and U.S. Pat. No. 2,982,966 to Dwight E. Priest. This art is representative of staple guns, and are herein incorporated by reference for their supportive teachings to assist one skilled in the art to understand the presently described invention herein. However, none of the above inventions and patents, taken either singly or in combination, is seen to describe the invention as claimed.

Preferably, a staple gun system should provide efficiency in use and, yet would operate reliably and be manufactured at a modest expense. Thus, a need exists for a reliable staple gun system to avoid the above-mentioned problems.

BRIEF SUMMARY OF THE INVENTION

In view of the foregoing disadvantages inherent in the known staple gun art, the present invention provides a novel staple gun system. The general purpose of the present invention, which will be described subsequently in greater detail is to provide a staple gun system designed for efficiency in use, whereby a large number of staples are available to be dispensed from a cartridge during a single duration.

A staple gun system is disclosed herein, in a preferred embodiment, comprising: a staple gun assembly having a frame, a grip-handle, a bumper, a driver, a top-guide, a cartridge port, a pusher-assembly, a roller, a pivot-pin, a return-spring, a cartridge, a cartridge-plate, cartridge springs (biasing means), a dragbar, a dejammer; wherein, as such, the staple gun system comprises the staple gun assembly. Those with ordinary skill in the art will now appreciate that upon reading this specification and by their understanding the art of components of hammer staplers as described herein, methods of guiding and advancing staples, aligning staples, returning the device back to a ready position, cartridge fitment, and the like will be understood by those knowledgeable in such art.

The staple gun assembly comprises in functional combination the frame, the grip-handle, the bumper, the driver, the top-guide, the cartridge, the cartridge port, the pusher-assembly, the roller, the pivot-pin, the return-spring, the cartridge-plate, the dragbar, and the dejammer. The frame provides a cover and mounting for the bumper, the driver, the top-guide, the cartridge port, the pusher-assembly, the roller, the pivot-pin, the return-spring, the cartridge-plate, and the dragbar.

The grip-handle is located on the frame and is structured and arranged such that a user is able to suitably grip the staple gun assembly for use; the staple gun assembly used in a hammering motion to install staples. The grip-handle preferably comprises rubber and is adjacent the frame in preferred embodiments. The bumper is located adjacent the driver, and the top-guide and the cartridge port guide the staples from the cartridge during the use; the staples moved via the cartridge springs (other advancing means may be used). The cartridge springs are normally in-tension and the cartridge springs, when in-tension advance the staples one by one. The pusher-assembly is used to advance the staples and the roller removably couples the top-guide and the cartridge port guide together for use. Various pusher-assemblies (means for advancing via spring pressure or other) may be used in alternate embodiments. The pivot-pin allows rotation of the frame in relation to the cartridge-plate. The pivot-pin allows the top-guide and the cartridge port guide to move in relation to the frame.

The return-spring acts in relation to the frame and the top-guide such that the top-guide is able to return to a normal-ready-for-use-position after the staple has been dispensed. The return-spring is normally in-tension. The cartridge-plate and the dragbar maintain positioning of the staples when feeding the staples with the pusher-assembly having a charger in certain embodiments. The dejammer is located on the frame and is structured and arranged to un-jam the staples during use (when a staple becomes jammed). The dejammer is located at the front-end of the frame and relationally speaking the dejammer is opposed to the charger (on the opposite end of the frame). This positioning is such that it is adjacent staples that may need to be un-jammed. The bumper controls movement of the return-spring with the staples being aligned on the cartridge plate and the dragbar for appropriate manipulation.

The staple gun assembly in combination with the cartridge is structured and arranged to provide a continuous feed of the staples for an extended duration. The cartridge is able to hold and feed at least 5000 staples for use. Embodiments may dispense different sized staples.

DETAILED DESCRIPTION

As discussed above, embodiments of the present invention relate to a stapling means and more particularly to a staple gun system as used to improve the efficiency of stapling on work projects such as insulating or the like.

Referring to the drawings by numerals of reference there is shown inFIGS. 1-4, various views of staple gun system100comprising: staple gun assembly110having a frame120with a grip-handle130(located at a back end of the frame120), housed within and on the frame120are various parts, like: a bumper132, a driver134, top-guide136, cartridge port138(housed on a middle section of the frame120), pusher-assembly142, roller (in certain embodiments), pivot-pin146, return-spring148, removable cartridge152(also referred to as cartridge housing, cartridge-plate154, cartridge springs156, dragbar158, and dejammer160. As such, staple gun system100comprises staple gun assembly110.

The staple placement mechanism, located at a front end of the frame120, is made up of the operational parts including the bumper132, the driver134, the dejammer160, and a cartridge port guide162, and is designed to extract a staple form within the staple gun frame and place it into a desired object.

The cartridge assembly152is made up of the cartridge housing152, the springs (biasing devices)156, the cartridge plate145, and a cavity (not shown or numbered) within the cartridge housing152and below the cartridge plate145, for storing the sets of staples (which are illustrated but not a claimed part of the invention). Thus, the assembly is designed to push one staple set at a time into the frame120, through the cartridge port138and onto the dragbar158, whereby the top-guide136will force the new staple set toward the bumper132to be ejected from the staple gun in a known fashion.

Referring now to grip-handle130; grip-handle130is located on a back portion of the frame120and is structured and arranged such that a user is able to suitably grip staple gun assembly110for use. Staple gun assembly110can also be used in a hammering motion to install staples. Bumper132is located adjacent driver134. Top-guide136and cartridge port guide162staples from cartridge152during use and staples are moved via cartridge springs156.

Pusher-assembly142is used to advance staples. Roller removably couples top-guide136and cartridge port guide162together for use. Pivot-pin146allows top-guide136and cartridge port guide162to move in relation to frame120. Return-spring148acts in relation to frame120and top-guide136such that top-guide136is able to return to a normal-ready-for-use-position after at least one staple has been dispensed. Cartridge-plate154and dragbar158maintain positioning of staples when feeding staples. Dejammer160is located on frame120and is structured and arranged to un-jam the staples during use. Bumper132controls movement of return-spring148that may be mounted along, over, or around an elongated section connected between the charger164and the top-guide136.

Staples are aligned on the cartridge plate154and dragbar158for sliding the staples therealong toward the bumper132. Staple gun assembly110in combination with cartridge152is structured and arranged to provide a continuous feed of staples for an extended duration. Cartridge152is able to hold and feed at least 2600 staples for use. Pusher-assembly142may comprise charger164in certain embodiments. Whereby, after the last staple loaded on dragbar158has been used, a user will pull back the charger164so that the top-guide slides past the cartridge port138thus allowing a new set of staples from cartridge152(from the force of the springs156), to drop in front of the top-guide136onto the dragbar158, and thus be fully recharged. Grip-handle130comprises rubber and is adjacent frame120. Dejammer160is located at a front-end of frame120. Pivot-pin146allows rotation between the frame120in relation to bottom-frame154. Wherein, the bottom frame154is designed to support the dragbar158, and house the charger, and pusher assembly pieces148,136,164in a known fashion. Note that, return-spring148is normally in-tension; and cartridge springs156are also normally in-tension.

Cartridge springs156when in-tension advance the staple sets one by one into the frame120, through the cartridge port138, and onto the dragbar158. In other words, the cartridge spring156(or biasing device) is positioned between a portion of the cartridge housing and cartridge plate to bias the cartridge plate away from one interior end of the cartridge housing and toward the interior of the frame. Dejammer160is located opposed to charger164. In one embodiment, cartridge152is able to hold and feed at least 5000 staples for use in certain embodiments. In another embodiment, cartridge152is able to hold and feed at least 7000, 8000, 9000 and 10,000 staples for use in other embodiments. Larger capacity embodiments are envisioned to hold more staples as per job application. Cartridge springs156may be linearly placed in relation to each other. Cartridge152comprises a length of 2½ inches in preferred embodiments; other lengths may be used in alternate embodiments.

It should be noted that staple gun system100may be sold as a kit comprising the following parts: at least one staple gun assembly110; at least one set of staples; at least one carrying container; and at least one set of user instructions. The kit has instructions such that functional relationships are detailed in relation to the structure of the invention (such that the invention can be used, maintained, or the like in a preferred manner). Staple gun system100may be manufactured and provided for sale in a wide variety of sizes and shapes for a wide assortment of applications, and staple sizes. Upon reading this specification, it should be appreciated that, under appropriate circumstances, considering such issues as design preference, user preferences, marketing preferences, cost, structural requirements, available materials, technological advances, etc., other kit contents or arrangements such as, for example, including more or less components, customized parts, different cartridge combinations, parts may be sold separately, etc., may be sufficient.

A method of use for staple gun system100(of staple gun system100) according to an embodiment of the present invention comprises the steps of step one holding staple gun assembly110; step two loading staple gun assembly110with cartridge152; manipulating and dispensing staples into at least one work product. Step three may comprise reloading staples into cartridge152and step four may comprise inserting a full cartridge152into staple gun assembly110for use.

It is noted that one advantage of the present design is that of the cartridge assembly. Specifically, the whole assembly is removable from the staple gun. Whereby, once all of the staple sets are gone, a user can remove the cartridge assembly and place new staple sets therein, in a sufficient amount to total hundreds of staples, even totaling up to 5000 or more. Whereby, a skilled artisan will realize that there will need to be a releasably locking or holding mechanism of some sort to removably hold the cartridge assembly thereto the frame when in operation, however, one such holding mechanism is not illustrated.

It is further noted, the cartridge assembly152is designed to retain many staple sets up and away from the interior of the frame120, and especially away from the dragbar158.

It is additionally noted, the staple sets are held up away from the dragbar 158xxx
