PROTECTIVE COVER FOR SEWER GRATES BACKGROUND OF THE INVENTION This invention pertains to a protective cover and more particularly to a protective cover for a sewer grate. The narrow wheels of modern bicycles often fall through the slots in conventional sewer grates thereby creating a serious safety hazard.
Therefore, it is a principal object of the invention to provide a protective cover for sewer grates which prevents the wheels of bicycles from falling therethrough.
A further object of the invention is to provide a protective cover for sewer grates which can be used on sewer grates having various dimensions.
A further object of the invention is to provide a protective cover for sewer grates having means thereon to prevent snow removal equipment from catching thereon. 1
A further object of the invention is to provide a protective cover for sewer grates including means for rigidly mounting the same thereon.
A further object of the invention is to provide a protective cover for sewer grates which does not interfere with the flow of water therethrough.
A further object of the invention is to provide a pro tective cover for sewer grates which is economical of manufacture, durable in use and refined in appearance.
These and other objects will be apparent to those skilled in the art.
BRIEF DESCRIPTION OF THE DRAWINGS This invention consists in the construction, arrangements and combination of the various parts of the device, whereby the objects contemplated are attained as hereinafter more fully set forth, specifically pointed out in the claims, and illustrated in the accompanying drawings, in which:
FIG. 1 is a perspective view illustrating the protective cover mounted on a conventional sewer grate:
FIG. 2 is a plan view of a conventional sewer grate:
FIG. 3 is an exploded perspective view of the protective cover of this invention:
FIG. 4 is a longitudinal sectional view illustrating the protective cover mounted on the sewer grate; and
FIG. 5 is an enlarged sectional view seen on lines 5--5 of FIG. 4.
DESCRIPTION OF THE PREFERRED EMBODIMENT The numeral refers generally to the protective cover of this invention while the numeral 12 refers to a conventional sewer grate. Sewer grate 12 is provided with a plurality of longitudinally extending bars 14 defining longitudinally extending openings 16 therebetween.
Cover 10 comprises a pair of spaced apart longitudinally extending bars 18 and 20. For purposes of description, bar 18 will be described as having opposite ends 22 and 24, upper end 26, and lower end 28. As seen in FIG. 3, bar 18 is provided with tapered portions 30 and 32 at its upper opposite ends for a purpose to be described in more detail hereinafter. Bar 18 is provided with a plurality of openings 34 formed therein adjacent the upper end thereof.
For purposes of description, bar 20 will be described as comprising opposite ends 36 and 38, upper end 40 and lower end 42. Bar 20 is provided with tapered portions 44 and 46 at its upper opposite ends as seen in FIG. 3. Bar 20 is also provided with a plurality of spaced apart openings 48 formed therein adjacent the upper end thereof.
The numeral 50 refers to transversely extending bars which are selectively slidably received in one of the openings 34 in bar 18 and one of the openings 48 in bar 20 as seen in FIG. 3. Each of the bars 50 is provided with a bolt opening 52 formed therein adapted to receive one of the bolts 54. Washer 56, lock washer 58 and nut are adapted to be received on each of the bolts 54.
The sewer grate 12 would ordinarily be removed from the opening in the street to facilitate the installation of the cover 10 thereon. The bars 18 and 20 are positioned in a pair of the openings 16 as seen in FIG. 1 with the bars 50 extending across the upper surface of the bars 14 as also seen in FIG. 1. The fact that the bars 50 are slidably received by the bars 18 and 20 permits the bars 18 and 20 to be moved towards or away from each other so that the device can accommodate sewer grates having various dimensions. The bolts 54 are then extended downwardly through the openings 52 with the washers 56 and 58 and nuts 60 being installed on the lower ends thereof. The washers 56 engage the lower ends of adjacent bars 14 as seen in FIG. 5 to positively maintain the protective cover in the proper position. The sewer grate may then be reinstalled in the opening in the street. I
It can be seen that the bars 50 prevent a bicycle wheel from passing downwardly through the openings 16 due to the relatively close spacing thereof. The tapered end portions on the bars 18 and 20 prevents snow removal equipment from catching on the same which could provide a serious maintenance hazard. Thus it can be seen that a protective cover has been disclosed for a sewer grate which prevents the narrow wheels of modern bicycles from falling through the slots or openings in the sewer grate. It can be seen that the protective cover of this invention accomplishes at least all of its stated objectives.
I claim:
1. A protective cover for a sewer grate having a plurality of longitudinally extending spaced apart bars defining elongated openings therebetween, comprising,
at least first and second elongated bar members adapted to be at least partially received in the spaced apart elongated openings in the sewer grate, a plurality of substantially horizontially disposed support bars secured to said first and second bar members and extending therebetween over the sewer grate, and means for securing the protective cover to the sewer grate, comprising, a bolt means extending downwardly through at least some of said support means between the. sewer grate bars, a washer means on the lower end of each of said bolts for engagement with a pair of the sewer grate bars, and a nut means on each of said bolts.

Claims (1)

1. A protective cover for a sewer grate having a plurality of longitudinally extending spaced apart bars defining elongated openings therebetween, comprising, at least first and second elongated bar members adapted to be at least partially received in the spaced apart elongated openings in the sewer grate, a plurality of substantially horizontially disposed support bars secured to said first and second bar members and extending therebetween over the sewer grate, and means for securing the protective cover to the sewer grate, comprising, a bolt means extending downwardly through at least some of said support means between the sewer grate bars, a washer means on the lower end of each of said bolts for engagement with a pair of the sewer grate bars, and a nut means on each of said bolts.
