DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0047] The present invention will now be described with reference to the accompanying figures, wherein the numbered elements in the following written description correspond to like-numbered elements in the figures.
[0048]
[0049] With reference to
[0050] In the embodiment shown, washer 22 has an outside diameter 54 (
[0051] Referring now to
[0052] As shown, seal ring 56 is placed over shaft 58 with shaft 58 then being passed through aperture 36 of washer whereby seal ring 56 is retained within cavity 38. Combination 20 is then assembled to a wall 26 by threading end 60 into the wall whereby surface 66 of head 62 is driven into engagement with seal ring 56 to contact and thereby compress seal ring 56 prior to surface 66 contacting washer 22 about opening 42. In such case, seal ring 56 is compressed against wall 40 and seat 44 of cavity 38, as well as against shaft 58 and surface 66 of fastener 24. Appropriate tightening of fastener 24 thus results in the creation of a seal between washer 22 and a barrier sheet 22 via sealing surface 48 of washer 22, as well as provides sealing between washer 22 and fastener 24 via seal ring 56. Combination 20 thereby provides sealing against moisture and air. In addition, the larger outer diameter of washer 22 relative to head 62 of fastener 24 provides retention of barrier sheet 32 to wall 26. That is, during construction the assembled combination 20 inhibits barrier sheet 32, which may comprise a thin plastic film, from ripping or pulling away. For example, prior to the assembly of the outer wall, wall portion 26 will be exposed to weather, such as wind and rain. Combination 20 thereby seals against wall 26 and retains barrier sheet 32 whereby separate barrier sheet retention fasteners and washers are not required.
[0053] Referring now to
[0054] Referring now to
[0055] Referring now to
[0056] An alternative washer that may be employed with fasteners 24, 124 or 224 is shown in
[0057] Referring now to
[0058] As noted, washer 222 is generally similar to washer 22, with the similar components or features of washer 222 including similar reference numbers, but with 200 added thereto. Accordingly washer 222 is plastic and is shown to include a solid upper or outer surface or upper wall 234, a central aperture 236 extending through washer 222, and a recess or cavity 238 in outer surface 234. Cavity 238 includes a wall 240 formed as a cylindrical bore that forms an opening 242 in outer surface 234, where the cylindrical bore 240 has a diameter greater than aperture 236 and does not extend through washer 222 to thereby form a seat 244.
[0059] Washer 222 further includes an underside 246 having an outer circumferential sealing surface 248, a plurality of ribs 250, and a central bottom surface 252 disposed about aperture 236. Also included is an inner circumferential sealing surface 253. Underside 246 is generally concave, with outer surface 234 being correspondingly generally conical. The concavity of underside 246 is defined in part by the recessing of bottom surface 252 and sealing surface 253 relative to sealing surface 248. That is, sealing surface 253 is recessed away from a plane defined by sealing surface 248. Thus, for example with reference to
[0060] In the illustrated embodiment, washer 222 includes two projections or prongs or arms 255a, 255b that extend downwardly from the underside 246 of washer 222 by about approximately 0.25 inches. The arms 255a, 255b are diametrically opposed relative to each other and include angled tips 257a, 257b to form sharpened points for puncturing and/or penetrating building materials, such as a barrier sheet or a pliable construction material. The location of arms 255a, 255b within or between the outer sealing circumference 248 and inner sealing surface 253 aid in inhibiting moisture and/or air from reaching arms 255a, 255b. It should be appreciated that alternative arrangements of arms may be employed. For example, an alternative washer may be constructed to include a single arm or more than two arms, or alternatively spaced or shaped arms, although the use of two or more arms aids in preventing rotation of washer 222 upon installation. Still further, washers 122 may also be provided with one or more arms. Bore 240 defines a diameter of approximately 0.78 inches with a depth of approximately 0.08 inches to define seat 244. Accordingly seal ring 56 affixed to fastener 24 and flange 64 are able to be received within cavity 238 when fastener 24 is assembled to washer 222.
[0061] Referring now to
[0062] Washer 322 further includes an engagement portion or member, which in the illustrated embodiment comprises a protuberance or projection or protrusion member 378 on or extending from wall 334, where protrusion member 378 aids in locating a fastener gun assembly on washer 322 for aligning and driving a fastener through washer 322. In the illustrated embodiment, protrusion member 378 includes an angled wall portion 380 that, as understood from the side view of
[0063] The inclusion of protrusion member 378 additionally creates a thicker central portion of washer 322 that has increased stiffness or rigidity. In contrast, the outer perimeter or surrounding portion of washer 322 defined by upper wall 322 that surrounds the central portion of washer 322 defined by protrusion member 378 is more flexible relative to protrusion member 378. Thus, when assembled, the surrounding outer portion is able to flex for improved sealing as discussed above in connection with
[0064] As noted, protrusion member 378 may be used for locating or positioning a fastener gun 400 (
[0065] With further reference to
[0066] In use, multiple washers 322 may be initially affixed to building materials, such as by way of pressing prongs 355a, 355b through a barrier sheet and into a foam material. Washers 322 will thus be maintained in place prior to receiving a fastener and without needing to be held by hand. An operator utilizing a fastener gun to which adapter 386 is mounted is then able to subsequently readily align the fastener gun with the washer 322 by way of the mating engagement of adapter 386 with protrusion member 378, and is then able to drive a fastener into washer 322 such that washer 322 is secured to the building, such as to a rigid substrate.
[0067] Although the engagement member of the illustrated embodiment is shown as an extending protrusion member 378 having a generally plateau configuration that is received within the receptacle 388 of adapter 386, it should be appreciated that alternative engagement members and/or adapter receptacle configurations may be employed. For example, as shown in
[0068] In use, one or more washers 322 are affixed to a barrier sheet and/or a penetrable or soft construction material of an inner wall in desired locations by pressing the prongs 255a, 255b into the barrier sheet and/or construction material. The prongs 255a, 255b thereby retain the washer 322 in place. Subsequently, an operator utilizing fastener gun 400 with adapter 386 affixed thereto is able to readily drive fasteners 401 into the inner wall assembly through washer 322 by locating the adapter 386 on the engagement member 378 such that the screw 401 is accurately centered with the aperture 336 in washer 322.
[0069] In the illustrated embodiment washer 322 does not include a cavity and seat for receiving the head of a brick tie fastener. However, washer 322 may alternatively be provided with such a cavity and a seat in like manner to washer 222 for applications requiring brick tie fasteners. Likewise, washer 222 may be formed to not include cavity 238 and seat 244, but rather be configured to include an aperture 336, opening 342 and chamfer 384 in similar manner to washer 322. Washer 322 also includes ribs, an inner sealing and the like as illustrated in connection with washer 222. Still further, although shown with prongs 255a, 255b, washer 322 may alternatively be formed to include fewer or more prongs, or alternatively arranged prongs, or may even be formed without prongs.
[0070] Although inner wall 26 is shown in the illustrated embodiment as comprising a barrier sheet 32 disposed over a deformable construction material 30 and, in turn, a rigid member 28, it should be appreciated that the present invention is useable with alternative wall assemblies. For example, the fastener and washer combinations discussed above may be utilized in a system that does not include a barrier sheet or a pliable construction material.
[0071] The washer and fastener combinations enable soft or pliable building materials, such as barrier sheets and insulation, to be rapidly, accurately and safely mounted to buildings. The washers via the prongs can be pre-spotted by hand to a vertical building surface by being pressed therein. Subsequently, via the use of a self-centering tool affixed to a fastener gun, screws or other types of fasteners, can be rapidly and accurately driven through the washers. The washers provide increased safety because the washers may be placed on the building material, and be self-retained via the prongs in particular embodiments, such that an operator or construction worker does not have to place their hand in front of the fastener gun to hold or insert the washer. Still further, the inclusion of sealing surfaces on the underside of the washer, and the inclusion of a sealing surface in the form of a chamfer about the aperture in the top side of the washer, inhibits water, moisture and/or air from getting past the undersurface of the washer or into the aperture and to the point at which the fastener penetrates the building materials.
[0072] Referring now to
[0073] Prongs 455a, 455b may be pressed into a building material surface, such as foam insulation, to aid in retaining washer 422 in place during assembly of fastener 24 to the building. Washer 422 is plastic and is shown to include a solid upper or outer surface or upper wall 434. Washer 422 further includes an underside 446 having an outer circumferential sealing surface 448, a plurality of ribs 450, and a central bottom surface 452 disposed about aperture 436. Also included is an inner circumferential sealing surface 453. Underside 446 is generally concave, with outer surface 434 being correspondingly generally conical. The concavity of underside 446 is defined in part by the recessing of bottom surface 452 and sealing surface 453 relative to sealing surface 448. That is, sealing surface 453 is recessed away from a plane defined by sealing surface 448. Thus, with washer 422 disposed against a wall prior to a fastener 24 being fully tightened such that washer 422 is not flexed and sealing surface 448 is against a sheet, sealing surface 453 would be slightly elevated from the sheet. Upon tightening fastener 24, however, washer 422 may flex such that sealing surface 453 and/or bottom surface 452 contacts the wall.
[0074] In the illustrated embodiment, washer 422 includes two projections or prongs or arms 455a, 455b that extend downwardly from the underside 446 of washer 422 by about approximately 0.25 inches. The arms may be of alternative lengths, however, such as shorter or longer, with the arms still operating to temporarily retain the washer when mounted to a vertical surface. The arms 455a, 455b are diametrically opposed relative to each other and include angled tips 457a, 457b to form sharpened points for puncturing and/or penetrating building materials, such as a barrier sheet or a pliable construction material. The location of arms 455a, 455b within or between the outer sealing circumference 448 and inner sealing surface 453 aid in inhibiting moisture and/or air from reaching arms 455a, 455b. It should be appreciated that alternative arrangements of arms may be employed. For example, an alternative washer may be constructed to include a single arm or more than two arms, or alternatively spaced or shaped arms, although the use of two or more arms aids in preventing rotation of washer 422 upon installation.
[0075] Washer 422 further includes an engagement portion or member, which in the illustrated embodiment comprises a protuberance or projection or protrusion member 478 on or extending from wall 434, where protrusion member 478 may be used to aid in locating a fastener gun assembly on washer 422 for aligning and driving a fastener through washer 422. In the illustrated embodiment, protrusion member 478 includes an angled wall portion 480 that, as understood from the side view of
[0076] The inclusion of protrusion member 478 creates a thicker central portion of washer 422 that has increased stiffness or rigidity. In contrast, the outer perimeter or surrounding portion of washer 422 defined by upper wall 434 that surrounds the central portion of washer 422 defined by protrusion member 478 is more flexible relative to protrusion member 478. Thus, when assembled, the surrounding outer portion is able to flex for improved sealing as discussed above.
[0077] Protrusion member 478 further includes a top surface 482 forming an upper ring about washer 422, where top surface 482 is generally parallel to the outer circumferential sealing surface 448 of underside 446. In particular embodiments, top surface 482 may form a ring of approximately 1/32 to 5/32 inches in width. An inwardly and downwardly oriented first surface or first chamfer or alignment surface 483 is disposed inwardly of top surface 482, where in the illustrated embodiment first chamfer 483 forms a conical surface. A central chamfer or second chamfer or screw head chamfer 484 is located inwardly of first chamfer 483, with chamfer 484 being provided at opening 442 of aperture 436, and where chamfer 484 forms a conical surface to receive the angled undersurface of a screw head, such as a bugle head style screw. Upon insertion of a bugle head screw into aperture 436, the angled undersurface of the screw head will mate or engage with the chamber 484 to thereby provide a seal against water, moisture and/or air passing through aperture 436. Thus, chamfer 484 comprises a sealing surface. As best understood from
[0078] Although first surface 483 is shown in the illustrated embodiment as a conical surface, it should be appreciated that first surface may alternatively be formed as a concave surface, with such a concave first surface inwardly and downwardly extending from top surface 482 to chamfer 484. In embodiments in which first surface 483 is concave, the concave first surface likewise defines a greater surface area than screw head chamfer 484.
[0079] As with protrusion member 378 of washer 322 discussed above, protrusion member 478 of washer 422 may be used for locating or positioning a fastener gun assembly relative to washer 422 whereby a fastener, such as a threaded screw, may be driven into aperture 436. For example, alignment tool or adapter 386 shown in
[0080] Still further, however, first chamfer 483 may be used to locate alternative fastener gun assemblies for insertion of fasteners through aperture 436 of washer 422, such as nose stem 486 shown in
[0081] Still further, rather than having a solid upper wall 434, washer 422 may include one or more through apertures or radial holes 435 (
[0082] In the illustrated embodiment, the diameter of aperture 436 is approximately 0.2 inches, the upper diameter of the opening of second chamfer 484 is approximately 0.35 inches where second chamfer 484 meets first surface 483, and the diameter of first surface 483 where it meets top surface 482 is approximately 0.7 to 0.825 inches.
[0083] Referring now to
[0084] In the illustrated embodiment, the diameter of aperture 536 is approximately 0.2 inches, the upper diameter of the opening of second chamfer 584 is approximately 0.35 inches where second chamfer 584 meets first surface 583, and the diameter of first surface 583 where it meets upper wall 534 is approximately 0.7 to 0.825 inches.
[0085] Referring now to
[0086] Changes and modifications in the specifically described embodiments can be carried out without departing from the principles of the present invention which is intended to be limited only by the scope of the appended claims, as interpreted according to the principles of patent law including the doctrine of equivalents.
