DETAILED DESCRIPTION

[0024] The present disclosure solves the above problems by providing a blade wear member having a slower wear rate than known blade wear members, and also by providing a blade wear member having a reduced tendency to partially break off, fracture, chip, or become otherwise damaged when the blade wear member engages a discontinuity in a travel surface.

[0025] Referring now to the drawings and particularly to FIGS. 1, 2, 3, 4, 5, 6, and 7, the blade wear member of one example embodiment of the present disclosure is generally illustrated and indicated by numeral 100. The illustrated example plow blade wear member 100 is configured to be removably and adjustably attached to a blade 50 of a blade assembly 40 that is attached or attachable to a vehicle 20. The vehicle 20 and the blade assembly 40 generally form a plow 10. In this illustrated embodiment, the blade wear member 100, the blade assembly 40, and the vehicle 20 are configured to operate as a snowplow, although it should be appreciated that the blade wear member of the present disclosure can be employed for or in conjunction with plow blades other than snowplow blades.

[0026] In this illustrated example embodiment, blade wear member 100 includes an elongated curved or arched body 104 having a first or top edge 108, a second or bottom edge 112, a third or right side edge 116, a fourth or left side edge 120, a front concave surface 124, and a rear convex surface 128. In this illustrated example embodiment, the blade wear member 100 includes a single body 104; however, it should be appreciated that the blade wear member can alternatively include two or more bodies that co-act to form the entire blade wear member and that are configured to be attached to a single blade as further discussed below with respect to FIG. 8.

[0027] The blade wear member 100 in this illustrated example embodiment has: (a) the first or top edge 108 extending parallel or substantially parallel to the second or bottom edge 112; (b) the third or right side edge 116 extending parallel or substantially parallel to the fourth or left side edge 120; and (c) the front concave surface 124 having the same or substantially the same arc or radius of curvature as the rear convex surface 128. In alternative embodiments of the blade wear member of the present disclosure: (a) the first or top edge and the second or bottom edge extend in intersecting planes; (b) the third or right side edge and the fourth or left side edge extend in intersecting planes; and/or (c) the front concave surface and the rear convex surface extend toward each other at the top section or the bottom section. The blade wear member 100 in this illustrated example embodiment has a substantially uniform thickness: (a) from the first or top edge 108 to the second or bottom edge 112; and (b) from the third or right side edge 116 to the fourth or left side edge 120. In alternative embodiments of the blade wear member of the present disclosure, the blade wear member has a non-uniform thickness: (a) from the first or top edge 108 to the second or bottom edge 112; and/or (b) from the third or right side edge 116 to the fourth or left side edge 120.

[0028] This illustrated example blade wear member 100 provides a desired curvature, thickness, and strength that are optimized for attachment to a plow blade, and particularly a snowplow blade. In this illustrated embodiment, the thickness of the blade wear member is at least approximately one inch. In this illustrated embodiment, the radius of curvature of the blade wear member is approximately 40 inches. In this illustrated embodiment, the distance from plane A (indicated by dotted line in FIG. 3) to plane B (indicated by dotted line in FIG. 3) is approximately 1.125 inches. It should be appreciated that in other embodiments of the present disclosure, the curvature, thickness, and strength of the plow blade wear member can vary.

[0029] The body 104 of this illustrated example blade wear member 100 defines a series of substantially horizontally aligned, off center, substantially vertically extending, spaced apart, oval attachment slots 130a, 130b, 130c, 130d, 130e, 130f, 130g, 130h, 130i, 130j, and 130k. The oval attachment slots 130a, 130b, 130c, 130d, 130e, 130f, 130g, 130h, 130i, 130j, and 130k extend though the entire body 104, and particularly from the front concave surface 124 to the rear convex surface 128. As shown in FIGS. 2, 4, 5, and 7, the oval shapes of the series of spaced apart attachment slots 130a, 130b, 130c, 130d, 130e, 130f, 130g, 130h, 130i, 130j, and 130k enable the blade wear member 100 to be attached to a blade such as blade 50 at spaced apart locations along the blade 50, and in each of a plurality of different positions or heights relative to the blade 50 or bottom edge of the blade 50.

[0030] More specifically, in this illustrated embodiment, as best seen in FIGS. 1, 4, 5, 6, and 7, the present disclosure includes a blade wear member attachment assembly including a front attachment bar 60, a rear attachment plate 65, a blade support 70, and a plurality of fasteners (such as bolts 80a, 80b, 80c, 80d, 80e, 80f, 80g, 80h, 80i, 80j, and 80k, and nuts 90a, 90b, 90c, 90d, 90e, 90f, 90g, 90h, 90i, 90j, and 90k) configured to attach the blade wear member 100 to the bottom section of the blade 50. The front attachment bar 60, the rear attachment plate 65, the blade 50, and the blade support 70 each include or define a corresponding series of openings such that the bolts 80a, 80b, 80c, 80d, 80e, 80f, 80g, 80h, 80i, 80j, and 80k can extend though the front attachment bar 60, the blade wear member 100, the rear attachment plate 65, the blade 50, and the blade support 70, and such that the nuts 90a, 90b, 90c, 90d, 90e, 90f, 90g, 90h, 90i, 90j, and 90k can be attached to the bolts 80a, 80b, 80c, 80d, 80e, 80f, 80g, 80h, 80i, 80j, and 80k to secure such components together as generally shown in FIGS. 1, 5, 6, and 7. The blade wear member 100 is positioned or sandwiched between the attachment bar 60 and the rear attachment plate 65 in this illustrated embodiment. It should be appreciated that other suitable blade wear member attachment assemblies can be used to attach the blade wear member 100 to the blade 50 in accordance with the present disclosure.

[0031] As mentioned above, the oval shapes of the attachment slots 130a, 130b, 130c, 130d, 130e, 130f, 130g, 130h, 130i, 130j, and 130k enable the blade wear member 100 to be attached to a blade at various different heights. FIG. 5 shows the blade wear member 100 attached to the blade 50 at an intermediate position relative to the blade 50. After the bottom second edge 112 of the blade wear member 100 wears down a designated amount or to a designated level (as shown in FIG. 7), the blade wear member 100 can be moved or adjusted downwardly one or more times and eventually such that the blade wear member 100 is attached to the blade 50 at the lowest position relative to the blade 50 for the series of attachment slots 130a, 130b, 130c, 130d, 130e, 130f, 130g, 130h, 130i, 130j, and 130k. FIG. 7 shows the blade wear member 100 attached to the blade 50 at this lowest position relative to the blade 50 for the series of attachment slots 130a, 130b, 130c, 130d, 130e, 130f, 130g, 130h, 130i, 130j, and 130k.

[0032] In certain embodiments of the present disclosure, after the first edge 112 of the blade wear member 100 has been further worn down to a further level, the blade wear member 100 can detached from the blade 50, turned upside down, and reattached to the blade 50 such that the series of attachment slots 130a, 130b, 130c, 130d, 130e, 130f, 130g, 130h, 130i, 130j, and 130k are used to attach the blade wear member 100 to the blade 50 in an upside down position. In other embodiments of the present disclosure that are not shown, a second series of horizontally aligned spaced apart attachment slots may be employed to accomplish the additional or alternative use or attachment.

[0033] The blade wear member 100 has a natural curvature (i.e., is curved in the normal or resting state). FIG. 6 best illustrates the curvature of the blade wear member 100 relative to the blade 50 and the rear attachment plate 65. FIG. 6 also illustrates that the bottom portion of the convex surface 128 of the curved blade wear member 100 is spaced apart from the rear attachment plate 65 a distance X, which in this illustrated example embodiment is approximately 0.25 inches at the lowest point of the rear attachment plate 65. FIG. 6 further shows that the gap between the curved blade wear member 100 and the rear attachment plate 65 narrows in an upward direction.

[0034] As the blade wear member 100 moves along a travel surface, the blade wear member 100 or bottom part thereof is strong enough to not flex or bend backward against its natural curvature when the blade wear member 100 or part thereof engages an object or discontinuity protruding from the travel surface at a designated force level. However, when the blade wear member 100 moves along a travel surface and engages an object or discontinuity protruding from the travel surface at a force level above the designated force level, the blade wear member 100 or bottom part thereof can flex or bend backward against its natural curvature. For example, the blade wear member 100 or bottom part thereof can flex or bend backward the entire distance X which is 0.125 inches in this illustrated example embodiment. The natural curvature of the blade wear member 100 causes the blade wear member 100 to be biased back to or return to its original shape or position. The gap between the curved blade wear member 100 and the rear attachment plate 65 facilitates this rearward bending of the bottom portion of the blade wear member 100 without causing damage to the blade wear member 100.

[0035] In this illustrated example embodiment, the blade 50, the front attachment bar 60, the rear attachment plate 65, and the blade support 70, the bolts 80a, 80b, 80c, 80d, 80e, 80f, 80g, 80h, 80i, 80j, and 80k, and the nuts 90a, 90b, 90c, 90d, 90e, 90f, 90g, 90h, 90i, 90j, and 90k, are all formed from a suitable metal such as steel. It should be appreciated that the blade 50, the front attachment bar 60, the rear attachment plate 65, the blade support 70, the bolts 80a, 80b, 80c, 80d, 80e, 80f, 80g, 80h, 80i, 80j, and 80k, and the nuts 90a, 90b, 90c, 90d, 90e, 90f, 90g, 90h, 90i, 90j, and 90k, can be formed from other suitable materials. It should further be appreciated that the rear attachment plate 65 is in part used to prevent damage to the blade 50. If the rear attachment plate 65 is damaged, it is much less expensive and time consuming to replace the rear attachment plate 65 than the blade 50.

[0036] In various embodiments of the present disclosure, the blade wear member is formed from multiple plies of a flexible material or element, such as rubber, to provide enhanced wear characteristics and to have the rigidity necessary for engaging a travel surface.

[0037] In various embodiments of the present disclosure, each layer or ply of the blade wear member of the present disclosure has a reinforcing material (such as a polymer material, a polyester material, a nylon or aliphatic or semi-aromatic polyamide material, a rayon or regenerated cellulose material, or a synthetic material) that reinforces the flexible material of the blade wear member to provide greater tensile strength. The flexible material is coupled with or bonded around each fiber of reinforcing material in various embodiments.

[0038] In various embodiments of the present disclosure, the blade wear member includes a plurality of layers or plies of reinforcing material integrated within a plurality of layers of flexible material. The quantity of reinforcing layers may vary in accordance with the present disclosure.

[0039] In various embodiments of the present disclosure, each layer of reinforcing material includes one ply of fibers angled in one direction and at least one other ply of fibers laid on top of or adjacent to the first ply at a substantially non-perpendicular different angle.

[0040] In various embodiments of the present disclosure, the multiple plies and the configuration in which the reinforcing material is positioned or layered within each ply causes (when the blade wear member is formed), the bottom edge or working edge of the blade wear member to include a plurality or pattern of indentations, serrations, or dimples. This pattern substantially decreases wear of the blade wear member

[0041] In various embodiments of the present disclosure, the blade wear member is formed from a plurality of separate pieces that are attached or otherwise suitably joined together to form the blade wear member.

[0042] In various embodiments of the present disclosure, the blade wear member is formed or cut from a used airplane tire.

[0043] In various embodiments, the blade wear member is formed or cut from a used airplane tire by: (a) removing the bead of the airplane tire; (b) trimming the remaining portion of the airplane tire to obtain a strip from the circumference of the airplane tire; (c) shaving the strip to the proper thickness if necessary; and (d) die cutting the shaved strip to the desired specifications (such as length).

[0044] In various embodiments of the present disclosure, the blade wear member is formed or cut from a used fiber reinforced airplane tire having an outer circumference of approximately 120 inches and a diameter of approximately 50 inches (such as a polymer fiber reinforced, polyester fiber reinforced, nylon or aliphatic or semi-aromatic polyamide fiber reinforced, rayon or regenerated cellulose fiber reinforced, or synthetic fiber reinforced airplane tire having an outer circumference of approximately 120 inches and a diameter of approximately 50 inches). Such airplane tires provide the desired radius of curvature, the desired at least approximately one inch thickness for the blade wear member, and the desired strength of the blade wear member. The curvature of the blade wear member formed or cut from a used airplane tire provides a desired spring action or resistance that causes the blade wear member to return to its normal position after being engaged by a discontinuity in the travel surface above certain force levels.

[0045] In various embodiments of the present disclosure, the blade wear member is formed or cut from a used airplane tire in lengths from six feet up to fifteen feet long. In various embodiments of the present disclosure, the aircraft tire employed has a one inch thickness and has a four foot height. The four foot height tire provides the desired radius of curvature for the blade wear member as explained above. In various embodiments of the present disclosure, the aircraft tire employed is up to ten feet wide.

[0046] Thus, in various embodiments of the present disclosure, the blade wear member is formed from a vulcanized rubber that has been treated with chemicals to improve the physical properties of the rubber and thus prevent the rubber from breaking down. Since the characteristics of vulcanized rubber prevent the rubber from being broken down and recycled similar to common plastics, the present disclosure provides an alternative use for existing used or worn out airplane tires. By utilizing vulcanized airplane tire rubber, the present disclosure provides the additional advantage of preventing the buildup of airplane tires in landfills.

[0047] In various embodiments of the present disclosure, the blade wear member is formed from the airplane tire by die cutting the airplane tire under compression such that each ply and the flexible material extends further than the plurality of reinforcing fibers that lay within that ply and the flexible material. However, since the reinforcing fibers are coupled to or bonded with the flexible material, as the flexible material expands, the fibers will be pulled or stretched along with the expanding flexible material. It should be appreciated that with the different thicknesses of the flexible material and not a lower coefficient of expansion, as the reinforcing fibers are pulled, a greater proportion of the reinforcing fibers, relative to the overall size, are stretched to expand substantially the same distance as the flexible material, and when the die cuts through the reinforcing material, a greater length of reinforcing material than the flexible material is cut. When the flexible material decompresses, the stretched reinforcing fibers (that have actually been cut more than the rubber material) will retract a greater distance than the flexible material to cause a plurality of indentations, serrations or dimples. That is, as described above, as a greater proportion (relative to their overall size) of the reinforcing fibers were stretched than the flexible material and subsequently cut away, less of the reinforcing fibers (proportionate to overall size) remain after the cut. In other words, when the flexible material and the reinforcing fibers retract to their pre-compression state, less of the fibers will remain (in proportion to their overall size) and thus the fibers will retract a greater distance than the flexible material, leaving an uneven edge or surface for each ply of the blade wear member. As described above, as the fibers and flexible material are coupled or bonded to each other, as the fibers retract, portions of the flexible material will retract more than other portions revealing the dimples. The indentations are formed in the flexible material around where the fiber has retracted.

[0048] The plurality of dimples provide a decreased amount of surface area for the blade wear member to engage the travel surface while still performing substantially the same function as a smooth edged blade wear member. When the bottom or working edge engages the ground surface to push snow, only the non-indented portion of the blade wear member edge will directly engage the ground surface. That is, without the entire edge of the blade wear member engaging the ground surface, the blade wear member edge will not be worn away as quickly and the blade wear member will not need to be replaced as often.

[0049] In various embodiments of the present disclosure, the blade wear member includes two or more different integrally connected sections or layers. The sections or layers are different in the spacing between the reinforcing fibers in each section or layer. In certain such embodiments, the first or inner layer includes the reinforcing fibers spaced relatively close together (in the direction from the concave front surface to the convex rear surface), and a second or outer layer including the reinforcing fibers spaced further apart (in the direction from the concave front surface to the convex rear surface).

[0050] Referring now to FIG. 8, the plow blade wear member of another example embodiment of the present disclosure is generally illustrated and indicated by numeral 1100. The illustrated example plow blade wear member 1100 is configured to be removably and adjustably attached to a blade 50 of a blade assembly that is attached or attachable to a vehicle. In this illustrated embodiment, the blade wear member 1100 includes multiple elongated curved or arched bodies 1104a and 1104b. In this embodiment, body 1104a has a first or top edge, a second or bottom edge, a third or right side edge a fourth or left side edge, a front concave surface, and a rear convex surface. In this embodiment, body 1104b also has a first or top edge, a second or bottom edge, a third or right side edge, a fourth or left side edge, a front concave surface, and a rear convex surface. In this embodiment, a blade wear member attachment assembly including a front attachment bar 1160, a rear attachment plate 1165, a blade support 1170, and a plurality of fasteners (such as bolts 1180a, 1180b, 1180c, 1180d, 1180e, 1180g, 1180h, 1180i, and 1180j, and 1180k, and nuts 1190a, 1190b, 1190c, 1190d, 1190e, 1190g, 1190h, 1190i, 1190j, and 1190k) is used to attach each of the bodies 1104a and 1104b of the blade wear member 1100 to the blade 50. In this illustrated example embodiment, the middle bolt and middle nut is not used. In this embodiment, the blade wear member bodies 1104a or 1104b can be replaced if damaged or worn without having to replace the other body. It should thus be appreciated from this alternative embodiment that the blade wear member of the present disclosure alternatively includes two or more bodies that form the entire blade wear member and that are configured to be attached to a single blade.
