DETAILED DESCRIPTION OF THE DRAWINGS

[0039] Paved surfaces are typically bordered by curbs. The curb can be made from concrete, paving blocks, Belgian blocks, or the like. One lateral face of the curb bounds and faces the paved surface, the opposite lateral surface faces an unpaved surface, which is soil, gravel, or the like. The protector or curb guard 10 is placed over the curb to mark the border between the curb and the paved surface.

[0040] A curb protector or curb guard 10 is depicted in FIGS. 1-6 and is configured as a U-shaped profile. The curb guard includes an anchoring piece 12 and a resting piece 14 that are slideably engageable with each other by way of an engagement mechanism 16 (FIG. 5). The engagement mechanism allows for the relative distance between the anchoring piece 12 and the resting piece 14 to be adjusted, as explained more fully below.

[0041] FIG. 1 is a bottom perspective view of the curb protector or curb guard 10 in an assembled configuration. The adjustable distance between resting piece 14 and anchoring piece 12 corresponds to a width of a curb, Belgian block, or the like upon which the curb guard 10 is installed. One or more spikes 22 are configured to penetrate the ground proximate to the curb into the unpaved area. The spikes preferably have a wedge shaped distal end that easily penetrates the unpaved surface.

[0042] As shown in FIG. 2A, the anchoring piece 12 is configured as an “L” shape having an elongated leg 20 and a shorter engaging leg 24. While the L-shape is considered a right angle, variation of about 10° is conceivable. It should be noted that the leg 24 can be a longer leg to accommodate wider curbs. The elongated leg 20 has the spikes 22, two such spikes are shown, with a cut out region 23 disposed therebetween. Alternatively, there can be a single spike 22 as shown in FIG. 2B. In other embodiments, additional spikes 22 can be provided. The spikes 22 have a wedge shaped blade at their distal end which assists in inserting and embedding the spike into the unpaved surface.

[0043] A plurality of gussets 26 are positioned at a bending region between legs 20 and 24 to provide strength to that region, as is known in the art. The leg 20 also includes one or more stiffening ribs 28 to provide strength to the one or more spikes 22. According to one aspect of the invention, the stiffening ribs 28 and other internal surfaces of the curb guard 10 have a protective coating to prevent curb damage, wherein the coating is foam, cloth, Teflon, rubber, or the like. As shown in FIG. 1 there are two spikes 22 each having a stiffening rib 28 extending along a longitudinal axis of the elongated leg 20. The anchoring piece 12 further includes an engagement hole 30 (FIG. 4), and one or more alignment ribs or gussets 32 on leg 24, the purposes of which will be explained below. While shown as a circular relief, the engagement hole can be configured as an elongated slot, a hole, or the like.

[0044] As shown in FIGS. 3A and 3B, the resting piece 14 comprises a horizontal leg 40 and a vertical leg 42, also configured as an “L” shape. While the L-shape is considered a right angle, variation of about 10° is conceivable. The horizontal leg 40 includes one or more stiffening ribs or guides 48 and one or more adjustment slots 46. In the embodiment depicted in FIG. 5, stiffening ribs or guides 48 are positioned on either side of a single adjustment slot 46. Alternatively, as shown in FIG. 3B, a single stiffening rib or guide 48 is positioned between two adjustment slots 46. The stiffening rib 48 is complementary to the alignment gusset or rib 32 of leg 24 such that when stacked, the alignment gusset or rib 32 will nest into the stiffening rib 48. The vertical leg 42 contains one or more push outs 44 for receiving an end of an indicator pole, preferably in a friction fit engagement. The push outs are generally C-shaped, semicircular, semi oval, pocket shaped, or the like. A bolt or other securing device can be provided on the push out 44 to secure the base of an indicator pole in the pushout 44. As shown in FIG. 5, fastener 50, such as a thumb screw or the like, is provided for releasably securing the anchoring piece 12 to the resting piece 14 in an adjustable and slideable manner.

[0045] FIGS. 4-7 depict the curb guard 10 in an assembled condition having the gussets or ribs 32 positioned in stiffening ribs or guides 48 and the fastener 50 securing the parts together by extending the fastener through the top surface of the horizontal leg 40 via the slot 46 and aligning it with engagement hole 30 of the anchoring piece 12. For this purpose, the engagement hole 30 may include threading, a welded nut, or the like. However, other securing mechanisms can also be used such as a screw and nut arrangement, a rivet, or the like. Thus, the slideable engagement mechanism 16 is comprised of the slot 46, the engagement hole 30, and the fastener 50. Alternatively, a portion of the material that is removed to form the engagement hole can be wrapped around the edges of the slot to form a sliding connection. With the anchoring piece 12 connected to the resting piece 14 as described, and with the fastener not fully tightened, the width or separation between the elongated leg 20 and the vertical leg 42 can be adjusted through slideable engagement of the parts along the slot 46. It should be noted that for a wider curb, an additional horizontal spacer can be provided that mates with both the horizontal leg 40 and the engaging leg 24. Once the parts are spaced in a desired manner, fastener 50 will then be tightened to secure the parts in that position.

[0046] The L-shape anchoring piece 12 and L-shaped resting piece 14 generally corresponds at least to the curb shown in FIGS. 8C and 8D. It should be noted that other shapes for the anchoring and resting pieces can be provided match other curb shapes. However, the L-shaped components can be used for any of the curbs shown in FIGS. 8A-8E.

[0047] One way of installing the curb guard 10 is as follows. With the anchoring piece 12 affixed to the resting piece 14 by way of a fastener in a loosely-engaged position, the curb guard can then be placed over a curb such that the elongated leg 20 of the anchoring piece 12 is positioned above a grass or dirt side of the curb and the vertical leg 42 of the resting piece 14 is positioned at the opposite side of the curb. The width of the curb guard can then be adjusted through slideable engagement whereupon at the desired separation, the fastener 50 will be tightened. Thereafter, the curb guard can be pressed into place such as by pressing down with a user's foot. This will cause the spikes 22 to be inserted into the grass or dirt to anchor the curb guard 10 in place. Typically, the spikes 22 extend vertically further than the vertical portion of the resting piece.

[0048] As will be appreciated, once in place, the curb will be positioned in a space defined by three surfaces, namely, elongated leg 20, horizontal leg 40 and vertical leg 42. It is also noted that the horizontal free edge of vertical leg 42 is preferably smooth so as to limit damage from possible contact with an asphalt or paver surface of a driveway or parking lot that is being plowed. Once the curb guard 10 is in position, an end of an indicator pole is inserted into the push outs 44. As such, the indicator pole is positioned proximate an interior boundary of a plowing area, as opposed to on an exterior boundary as in the case of the prior art discussed above. Moreover, if an indicator pole becomes dislodged for any reason, it can be easily reinserted into the push out 44 without concern for a possible freezing condition of the soil, unlike the prior art.

[0049] The curb guard 10 and anchoring piece 12 are preferably made of stamped metal but can be formed of other durable material such as molded or extruded hard plastic. Also, it should be noted that both parts need not be made of the same material. For example, the anchoring piece 12 containing the spikes could be made of a metal material whereas the resting piece 14 can be made of a durable plastic. It is also noted that although two spikes 22 are shown, a single spike may also be employed as an alternative design (FIG. 3B). Furthermore, although two push outs 44—aligned with each other to provide a guide and insert area for an end of an indicator pole—are provided, a single elongated push out or pocket would likewise suffice.

[0050] An alternative embodiment of the resting piece 14 is depicted in FIG. 3B. Unlike FIG. 3A, the resting piece in FIG. 3B contains two adjustment slots 46 and a single guide 48. In this embodiment, the single guide 48 would accommodate a single rib 32 in the anchoring piece 12, and two engagement holes 30 would be positioned, each under a respective adjustment slot 46 and then fastened with a respective fastener 50. Aside from those variations, that alternative curb guard embodiment would function the same as explained above.

[0051] FIG. 7 shows the curb guard 10 in its assembled condition with an indicator pole 60 and an optional flag 65. The curb guard 10 is installed on a curb 90 that surrounds a paved surface 80. Curb 90 is shown as a wire frame. The anchoring piece 12 and the resting piece 14 overlap on the top surface 75 of the curb 90. The vertical leg 42 of the resting piece rests on the lateral face 85 of the curb. The indicator pole can be a reflective material or coated with a reflective material. Similarly, the flag 65 can be reflective. The indicator pole 60 is inserted into the push out 44, which denotes the edge of the paved surface 80. The indicator pole is held in place by a friction fit and/or locked in place with a fastener 70. The fastener 70 can be a bolt, screw, rivet, or the like. It should be noted that the push out 44 can be configured as a single pocket or as additional material bonded to the vertical leg 42.

[0052] According to one aspect of the invention, the curb guard is formed as a single piece that is nonadjustable. The single piece can be stamped metal or molded plastic. The single piece construction can be manufactured in standard sizes corresponding to general curb dimensions and shapes, several of which are shown in FIG. 8A-8E. It should be noted that other shapes and sizes are conceivable.

[0053] An alternative embodiment of the curb guard 10 further comprises a liner on its internal surface configured to contact the curb and protect the curb. The liner can be cloth, foam, or the like. The liner can be affixed by an adhesive to the curb guard on its internal surface.

[0054] Thus, while there have shown and described and pointed out fundamental novel features of the invention as applied to a preferred embodiment thereof, it will be understood that various omissions and substitutions and changes in the form and details of the devices illustrated, and in their operation, may be made by those skilled in the art without departing from the spirit of the invention. For example, it is expressly intended that all combinations of those elements and/or method steps which perform substantially the same function in substantially the same way to achieve the same results are within the scope of the invention. Moreover, it should be recognized that structures and/or elements and/or method steps shown and/or described in connection with any disclosed form or embodiment of the invention may be incorporated in any other disclosed or described or suggested form or embodiment as a general matter of design choice. It is the intention, therefore, to be limited only as indicated by the scope of the claims appended hereto.
