Staple Gun

Abstract

A staple gun for driving pins into a surface. The staple gun includes a housing designed to facilitate manual actuation of a drive member, such that the drive member passes through an open interior channel in the housing to guide a bearing pin to strike a pre-positioned drive pin to penetrate through and affix itself to a surface. The drive member further includes a handle designed to receive the strike force used to actuate the drive member through the open interior channel of the housing. A spring is designed to push the handle and the drive member upward and away from the housing after each actuation of the handle, and a removable linchpin designed to restrict the range of motion of the drive member within the housing and to ensure that the drive member remains partially inserted within the housing.

DETAILED DESCRIPTION OF THE INVENTION

[0024] Reference is made herein to the attached drawings. Like reference numerals are used throughout the drawings to depict like or similar elements of the staple gun. For the purposes of presenting a brief and clear description of the present invention, the preferred embodiment will be discussed as used for a staple gun. The figures are intended for representative purposes only and should not be considered to be limiting in any respect.

[0025] Referring now to FIGS. 1A, 1B, and 1C there are shown a perspective view, a cross-sectional view along line AA, and a disassembled view of the components of an embodiment of the staple gun respectively. The staple gun 1000 is configured to drive pins into a surface and comprises a housing 100 having an open interior channel 115 disposed between an open first end 110 and a second end 120, wherein the open first end 110 and the open interior channel 115 are configured to facilitate actuation of a drive member 200, and the second end 120 is fully enclosed except for a pin hole sized second channel 125 configured to receive and facilitate actuation of a bearing pin 300. In some embodiments the housing 100 tapers inward such that the first end 110 is broader than the second end 120. The staple gun 1000 for driving pins into a surface also provides a plurality of drive pin caps 700, such that each one has a drive pin 710 disposed therein configured to be inserted into the second channel 125. Once inserted into the second channel 125 each drive pin 710 is held in place directly beneath the bearing pin 300 such that the drive pin 710 can be driven into a surface.

[0026] In the illustrated embodiment the drive member 200 is an elongated cylindrical member that includes a first end 210 removably attached to a handle 500, and a second end 220 with the bearing pin 300 disposed thereon, such that a force applied to the handle 500 will actuate the drive member 200 through the open interior channel 115 of the housing 100 and simultaneously actuate the bearing pin 300 through the second channel 125 of the housing 100. In this embodiment, the handle 500 includes a partial sphere 510 having a planar face 520 with an open interior channel 530 disposed therein such that the drive member 200 can be removably inserted therein, and the handle 500 is configured to withstand the strike-force used to embed a drive pin 710 into a surface. The spherical portion provides a simple and convenient means for a user to strike down on the handle bare handed and still apply uniform force downward to drive the drive member 200.

[0027] Additionally, the illustrated embodiment shows where a spring 400 circumscribes the drive member 200 while disposed between the handle 500 and the housing 100 is configured to immediately push the handle 500 and the drive member 200 upward and away from the housing 100 after each actuation of the handle 500. By pushing the handle 500 and the drive member 200 upward and away from the housing 100 after each actuation the handle is automatically reset to a position wherein the device is again ready to be used. Furthermore, a removable linchpin 600 is sized and proportioned to slide through a first aperture 140 disposed on the outer surface of the housing 100 and into a slot 230 disposed in the body of the drive member 200, such that the drive member 200 can be held in place within the housing 100 when the linchpin 600 is inserted.

[0028] Referring now to FIG. 2 there is shown a close-up view of a removal pin being inserted through a first aperture to uninstall a linchpin through a second aperture in an embodiment of the staple gun. In the illustrated embodiment the slot 230 disposed in the drive member 200 is positioned closer to the bearing pin 300 than to the handle 100 such that when the linchpin 600 is inserted therein the drive member 200 secured within the housing 100 and the range of upward motion for the drive member 200 limited to the height of the slot 230. When the linchpin 600 is removed the drive member 200 has an unlimited range of upward motion and can be fully removed from the channel 115 of the housing 100. To remove the linchpin 600 a pin hole sized second aperture 150 is provided. The second aperture s disposed on the outer surface of the housing 100 such that a line of sight is created from the second aperture 150 through the slot 230 disposed in the drive member 200 to the first aperture 140 disposed on the outer surface of the housing 100.

[0029] In some embodiments a removal pin 800 is also provided, such that the removal pin 800 is configured to slidably insert through the second aperture 150 and push the linchpin 600 out through the first aperture 140. Additionally, the second aperture 150 is sized and proportioned to be finer than the first aperture 140 such that the removal pin 800 can pass through bother apertures 140, 150, but the linchpin 600 is prevented from completely passing through both apertures 140, 150 and remains in place to secure the drive member 200 within the channel 115 of tile housing 100.

[0030] Referring now to FIGS. 3A and 3B there are shown a front view and a top-plan view of a drive rain cap in an embodiment of the staple gun, respectively. In the illustrated embodiment each drive pin cap 700 comprises a planar base 720, a central pinhole 730, a drive pin 710, and a sidewall 740, such that the drive pin 710 is removably disposed in the central pinhole 730.

[0031] It is therefore submitted that the instant invention has been shown and described in what is considered to be the most practical and preferred embodiments. It is recognized, however, that departures may be made within the scope of the invention and that obvious modifications will occur to a person skilled in the art. With respect to the above description then, it to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

[0032] Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact constriction and operation shown and described,and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
