Benefits of technology

The patent describes a drain cover that can be used with different types of drains such as roof, floor, and street grating. It is easy to install and remove, and prevents blockages while still allowing fluids to flow through. Additionally, the cover has an extended outer flow ring that improves its ability to collect fluids. Overall, this drain cover provides an efficient and flexible solution for managing fluid flow.

Problems solved by technology

Because roof drains are typically exposed to the elements, they are susceptible to damage or clogging from a variety of sources.
Also, due to their isolation, any damage or tampering with such drains may go unnoticed until a problem occurs with the functioning of the drain.
Further, harmful elements may damage or clog the drains, such as hail or strong winds and solid debris carried by such elements.
Other drains besides those intended for the roof may also be susceptible to similar problems.
For example, street drains may be susceptible to clogging from collected street debris or to damage by passersby.
Therefore, drains in many contexts may be exposed to danger.
However, typical drain covers have many drawbacks.
This limits the number of types of drains that may be fitted with the covers.
In addition, conventional drain covers easily clog and prevent the passage of fluid, due to leaves or other debris building up along the outside of the covers.
Further, the gravel guard on typical covers severely impede the flow of fluids into the cover as well.

first embodiment

[0281]FIG. 14A is a perspective view of a drain cover assembly 1400 including the cover 1300 attached to a clamping collar 1430 as attached by an embodiment of locking clip assemblies 1434. The collar 1430 may attach to a drain and to the cover 1300 to secure the cover 1300 over the drain. The locking assemblies 1434 may secure the cover 1300 to the collar 1430.

[0282]FIG. 14B is a partial cross-sectional view of the assembly 1400 of FIG. 14A showing a close up of one locking clip assembly 1434. The locking clip assembly 1434 includes a wingnut 1443 securing a housing 1440 to a base 1441. The housing 1440 is vertically secured by the ribs 1340 of the cover 1300. The base 1441 has a radially outward, forward foot 1445 that slides radially outward and underneath the outer edge 1330 of the cover 1300. The foot 1445 may be located underneath a tab 1435 of the collar 1430. The tab 1435 prevents vertical movement of the base 1441. The base 1441 may be moved radially outward between the rib...

second embodiment

[0284]FIG. 15A is a perspective view of a drain cover assembly 1500 having the cover 1300 attached to a clamping collar 1530 as attached by the locking clip assemblies 1434. The cover 1300 includes the ribs 1320 and the upper dome 1310. The collar 1530 includes an outer wall protruding upward and having gaps therein to allow for horizontal flow of fluid through the gaps.

[0285]FIG. 15B is a partial cross-sectional view showing a close up of one of the locking clip assemblies 1435 and the collar 1530. As shown, the foot 1445 of the base 1441 may be located under a corresponding portion of the collar 1530 to prevent vertical movement of the locking assembly 1435. Further, the housing 1440 includes a horizontal groove 1448 in a side thereof into which one of the ribs of the cover 1300 is received. There is an additional groove 1448 on the opposite side of the housing 1440, which is not visible. Thus the ribs vertically secure the locking assembly 1435 with the cover 1300. The wingnut is...

Abstract

A drain cover assembly. The cover may be used with roof drains or other drains and allow for fluid collection into the drain even with buildup of debris around or on the cover. The cover may have a lower flange or portion with a large area and extending outwardly in an arcuate configuration and having openings for fluid flow. The lower portion may be oriented at a small angle with respect to the horizontal. An upper portion may be connected to the lower portion and may be more vertically-oriented than the lower portion and also extend arcuately and having openings. Locking assemblies may be adjustable to secure the cover to a clamping collar over a drain. The locking assembly may include a base that slidingly engages the collar, and a housing that is secured over the base and to secure the cover to the collar.
