DETAILED DESCRIPTION

As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.

Referring to FIGS. 1 and 2, a fastening tool assembly, such as a manual staple gun is illustrated and referenced by numeral 20. Although the fastening tool assembly 20 is illustrated and described as a staple gun, the invention contemplates any fastening tool that drives a fastener into a workpiece.

The staple gun 20 has a housing 22, which may be formed from a pair of housing portions 24, 26. The housing 22 has a workpiece contact surface 28 for engaging a workpiece. A fastener outlet 30 is provided through the contact surface 28 for egress of fasteners from the staple gun 20. A magazine assembly 32 is also provided in the housing 22 for storing fasteners, and conveying the fasteners to the outlet 30.

The housing 22 also provides a grip 34 spaced apart from the magazine assembly 32 with an opening, or finger well 36, between the grip 34 and the magazine assembly 32, for receipt of a user's fingers when grasping the grip 34. A handle 38 is pivotally connected to the housing 22 for manual actuation for driving a fastener from the outlet 30. In operation, a user inserts her or his fingers into the finger well 36 for contact with the grip 34. The user wraps her or his thumb about the handle 38 so that the user's palm engages the handle 38. By squeezing the grip 34 and handle 38, or by pressing the handle 38 toward the housing 22, the user actuates the staple gun 20 thereby driving a staple out of the staple outlet 30.

The magazine assembly 32 receives a strip of fasteners that are typically adhered collectively in a linear array by an adhesive. The magazine assembly 32 includes a magazine receptacle 40 that is oriented longitudinally to the housing 22. The receptacle 40 may formed integrally with the housing 22, or may be formed from a separate component or material, such as stamped steel, and may be assembled into the housing 22. In the depicted embodiment, the receptacle 40 provides a cavity 42 within the housing 22. The cavity 42 is accessible through an intake opening 44 formed through the contact surface 28 of the housing 22.

Referring now to FIGS. 1-3, a magazine body 46 is received within the receptacle 40 to translate longitudinally for extension from the housing 22 for reloading of fasteners to the magazine assembly 32. The body 46 provides a guide 48 for receiving the fasteners. A spring-loaded pusher 50 is provided upon the guide 48. The pusher 50 has a forward end 51 that is sized corresponding to a fastener for a surface contact against a trailing fastener of the fastener strip. Insertion of the body 46 into the receptacle 40 causes the pusher 50 to retract along the guide 48 as the guide 48 receives fasteners. The fasteners engage the pusher 50, thereby loading the pusher spring. The spring-loaded pusher 50 presses the fasteners toward the fastener outlet 30 so that as each fastener egresses the outlet 30, the next sequential fastener is translated into position with the fastener outlet 30. In the retracted position of the magazine body 46, the body 46 also encloses the receptacle 40 and may form part of the contact surface 28.

A latch mechanism 52 is provided on the magazine body 46. The latch mechanism 52 is mounted to the magazine body 46 to pivot and translate relative to the body 46. The latch mechanism 52 is spring-loaded to maintain engagement of the latch mechanism 52 with a corresponding notch 53 (FIG. 2) on the housing 22. The user presses the magazine body 46 into the receptacle 40 whereby a leading edge 54 of the latch mechanism 52 engages the housing 22, translating the latch mechanism 52 toward the magazine body 46. As the latch mechanism 52 aligns with the notch 53, the latch mechanism 52 is extended into the notch 53, thereby latching the magazine body 46 into the receptacle 40. In order to retract the magazine body 46, the user pulls the latch magazine 52 down until it disengages from the notch 53.

In the extended position of the magazine body 46, a user may inadvertently attempt to install a fastener strip upon the guide 48 of the magazine body 46. Accordingly, a blocker 56 is provided upon the magazine body 46 on a side of the magazine body 46 that is spaced apart from the intake opening 44. The blocker 56 is illustrated disassembled from the magazine body 46 in FIG. 4. The blocker 56 may formed as a plate with a transverse width that is greater than a width of the fasteners to act as a staple stopper and prevent inadvertent installation of the fasteners upon the magazine body 46. Moreover, the blocker 56 has a transverse width greater than a width of the magazine body 46 to prevent inadvertent loading of the fasteners upon the magazine body 46.

Instructional indicia 58 can be provided upon the blocker 56 to instruct the user not to insert fasteners directly upon the guide 48. The instructional indicia may also instruct the user to insert fasteners into the intake opening 44 thereby instructing the user on proper installation of fasteners. The instructional indicia 58 could be provided upon any surface of the magazine body 46 for informing the user at any exposed surface.

The blocker 56 includes a keyed notch 60 for assembling the blocker 56 to the latch mechanism 52. The latch mechanism 52 includes an upright key 62 extending through the notch 60 in the blocker 56 for retaining the blocker 56. The blocker 56 extends over the pusher 50 and the guide 48; and the blocker 56 provides clearance for translation of the pusher 50 and fasteners upon the guide 48. A slot 64 is provided within the receptacle 40 for receiving the blocker 56 and maintaining the blocker 56 spaced apart from the guide 48, the pusher 50 and the fasteners.

While various embodiments are described above, it is not intended that these embodiments describe all possible forms of the invention. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the invention. Additionally, the features of various implementing embodiments may be combined to form further embodiments of the invention.
