[0021] The powered fastener driving tool 100 of this illustrated example embodiment generally includes: (a) a housing 110 including a main compartment 200 and a handle 300 extending from the main compartment; (b) an end plug 400 removably attached to the handle 300; (c) a power source or supply assembly (not shown) positioned in the housing 110; (d) a fastener supply assembly 500 configured to receive fasteners (not shown) and suitably connected to or supported by the housing 110; (e) a fastener driving assembly (not shown) in the main compartment 200 of the housing 110; (f) a trigger mechanism 600 (partially shown) connected to or supported by the housing 110; (g) a WCE 700 connected to or supported by the main compartment 200 of the housing 110: and (h) a belt hook assembly 800 rotatably connected to the end plug 400.

[0022] More specifically, in this illustrated example embodiment, the housing 110 includes a main compartment 200 and a handle 300 extending from and integrally formed with the main compartment 200. The main compartment 200 includes a main housing 215 and an end cap 220 removably attachable to the main housing 215 by a plurality of attachment members such as bolts 232, 234, and 236. The main housing 215 and the end cap 220 define an interior component chamber (not shown). In one embodiment, the main housing 215 and the handle 300 are cast from or in a single mold. In other embodiments, the main housing 215 and the handle 300 can be separately formed and then integrally attached. The handle 300 includes a top section 310 adjacent to the main housing 215, a middle section 320, and a bottom section 330. The bottom section 330 includes two end plug attachment member receivers (not shown) sized, shaped, or otherwise configured to receive the attachment members, such as bolts 490 and 492, that removably attach or secure the end plug 400 to a bottom section 330 of the handle 300.

[0023] In this illustrated example embodiment, the end plug 400 includes a body 410 removably attachable to the bottom section 330 of the handle 300 by the bolts 490 and 492. More specifically, the body 410 includes: (a) a mounting base 412; (b) a pneumatic connector receiver 430 extending outwardly from the mounting base 412; (c) a belt hook receiver 450 extending outwardly from the mounting base 412; and (d) a mounting bracket 470 extending downwardly from the mounting base 412.

[0024] The mounting base 412 is sized, shaped, or otherwise configured to be positioned adjacent to the butt end or bottom end (not shown) of the bottom section 330 of the handle 300. The mounting base 412 defines two spaced apart apertures 491 and 493 sized, shaped, or otherwise configured to respectively receive the bolts 490 and 492 which secure the mounting base 412 to the butt end or bottom end (not shown) of the bottom section 330 of the handle 300. It should be appreciated that other suitable mechanisms may be employed to secure the end plug 400 to the handle 300 in accordance with the present disclosure.

[0025] The pneumatic connector receiver 430 extends outwardly from the mounting base 412 and has a partially cylindrical body 432 that defines an opening 435 sized, shaped, or otherwise configured to receive a pneumatic connector (such as the pneumatic connector 42 shown in FIG. 1). The pneumatic connector receiver 430 has a threaded interior surface 438 that defines the opening 435 and that enables the pneumatic connector to be screwed into and out of the opening 435 and thus the pneumatic connector receiver 430. In this illustrated embodiment, the pneumatic connector receiver 430 extends at an offset upwardly directed angle from the fastener supplier 500 or magazine) to ensure that the air hose is out of the way during reloading of the fastener supplier 500 or magazine.

[0026] The belt hook receiver 450 extends outwardly from the mounting base 412 and has a generally cylindrical body 452 that defines an opening 458 configured to receive an attachment member such as bolt 860. The belt hook receiver 450 has a threaded interior surface 452 which enables the attachment member such as bolt 860 to be screwed into and out of the opening 458. The belt hook receiver 450 and specifically the generally cylindrical body 452 has a relatively smooth outer surface 456 which enables the belt hook 810 to rotate about belt hook receiver 450 as further discussed below.

[0027] The mounting bracket 470 extends downwardly from the mounting base 412 and includes a leg 472 including a foot 473 which defines two openings 476 and 478 sized, shaped, or otherwise configured to receive suitable an attachment members such as bolts 477 and 479 for attaching the mounting bracket 479 and the end plug 400 to the fastener supply assembly 500.

[0028] In this illustrated embodiment, the mounting base 412, the pneumatic connector receiver 430, the belt hook receiver 450, and the mounting bracket 470 are integrally formed from a suitable metal such as steel or aluminum. It should be appreciated that the end plug can be made from other suitable materials and in other suitable shapes in accordance with the present disclosure.

[0029] In this illustrated example embodiment, a suitable gasket or washer 495 is positioned between the end plug 400 and the bottom end of the handle 300 to provide a secure air-tight connection.

[0030] In this illustrated example embodiment, the power source or supply assembly (not shown) is positioned in the housing 110 and includes one or more channels that extend through the handle 300 and which defines an air inlet (not shown) in the handle 300. This enables the pneumatic connector to communicate air from the pneumatic air supply line (not shown) to the air inlet in the handle 300 to provide pressurized air to the power source.

[0031] In this illustrated example embodiment, the fastener supply assembly 500 is configured to receive fasteners (not shown) and is connected to fastener driving assembly extending from the housing 110 and to the leg 472 of the end plug 400. The fastener supply assembly 500 is configured to supply fasteners to the fastener driving assembly.

[0032] In this illustrated example embodiment, the fastener driving assembly is partially in the main compartment 200 of the housing 110 and partially extends from the main compartment 200 of the housing 110.

[0033] In this illustrated example embodiment, the trigger mechanism 600 is partially in the upper section 310 of the handle 300 of the housing 110 and partially extends from the upper section 310 of the handle 300 of the housing 110. The trigger mechanism 600 includes a trigger which is supported by and extends from the handle 300 of the housing 110.

[0034] In this illustrated example embodiment, the WCE 700 is connected to and extends from the main compartment 200 of the housing 110.

[0035] In this illustrated example embodiment, the belt hook assembly 800 is movably and, specifically, rotatably connected to the end plug 400. The belt hook assembly 800 includes a generally L-shaped belt hook 810, a spring 840, a washer 850, and an attachment member such as bolt 860. The spring 840 is sized, shaped, or otherwise configured to be positioned about or journaled about the belt hook receiver 450 of the end plug 400 as shown in FIGS. 2 and 3. The spring 840 is configured to apply suitable pressure or friction to the belt hook 810 such that the belt hook 810 can be rotated, but does not loosely rotate. The bolt 860 suitably secures the washer 850, the belt hook 810, and the spring 840 to the belt hook receiver of the end plug 400 such that the belt hook 810 is rotatable about the belt hook receiver 450 of the end plug 400 as further described below. The belt hook 810 includes a hooking hand 812 (having a hooking finger 813), an extension arm 820 connected at one end to the hooking hand 812, and a mounting shoulder 830 connected to the other end of the extension arm 820. The mounting shoulder 830 includes a body 832 defining a central opening 834 having an inner diameter larger than the outer diameter of the belt hook receiver 450 such that the belt hook 810 is rotatable about the belt hook receiver 450 of the end plug 400. The body 832 of the mounting shoulder 830 further includes: (a) a first end wall 836 having a first end plug engagement edge 837; (b) a second end wall 838 having a second end plug engagement edge 839; (c) a third end wall 840; and (d) a fourth end wall 842. The mounting shoulder further includes a curved edge 839A between edge 839 and edge 837.

[0036] The belt hook 810 is rotatable from and between a first or stored position shown in FIGS. 2 and 4 to a second or in-use position shown in FIGS. 3 and 5.

[0037] In the first or stored position, the end wall 838 is adjacent to the wall 402 of the body 410 of the end plug 400, the extension leg 820 extends toward the fastener supplier 500, and the hooking hand 812 extends adjacent to the fastener supplier 500. In the first or stored position, the second end plug engagement edge 839 of the second end wall 838 engages the wall 402 but is curved or configured to allow rotation of the wall 436 relative to wall 402.

[0038] In the second or in-use position, the end wall 836 is adjacent to and engages the wall of the 402, the extension leg 820 extends outwardly, and the hooking hand 812 extends outwardly to enable an operator to hang the tool on an object such as the operator's belt. In the second or in-use position, the first end plug engagement edge 837 of the first end wall 836 engages the wall 402 to prevent further upward rotation of the belt hook 810. This prevents the belt hook 810 from further rotating upwardly to an undesired position.

[0039] The belt hook 810 is thus rotatable from a first storage position shown in FIGS. 2 and 4 to a second or in-use position shown in FIGS. 3 and 5. This enables an operator of the tool 100 to use the belt hook when desired and prevents the belt hook from moving to an undesired further upwardly rotated position.

[0040] This end plug 400 and belt hook assembly 800 configuration solve the above issues, and specifically if the mounting bracket 470 breaks or cracks, only the end plug 400 (instead of the entire housing 410) needs to be replaced. Likewise, if the belt hook retainer 450 breaks or cracks, only the end plug 400 (instead of the entire housing 410) needs to be replaced.

[0041] It will be understood that modifications and variations may be effected without departing from the scope of the novel concepts of the present invention, and it is understood that this application is to be limited only by the scope of the claims.
