1. Field of the Invention
The present invention relates to step covers and, more particularly, to a wraparound step cover.
2. Description of Related Prior Art
Numerous types of step covers have been used over the years. The most common step cover is simply material, usually a rubber composition, which is attached to the top of a step by a mastic, brads, or the like. Such a cover may extend partially or fully along the top surface of the step. Some step covers wrap partially around a step such that the opposed edges of the cover extend onto the sides or bottom of the step and are attached by nails, brads, or a mastic. A potentially removable step cover extends partially about each longitudinal edge of a step and partially on to the bottom of the step. The opposing ends of the cover at the bottom of the step are latched with one another by cords or the like penetrably engaging apertures along the edges of the cover under the step.
The first two types of covers discussed above are usually permanently or at least semi-permanently attached to a step. This creates difficulties when the covers are to be replaced due to wear, damage or discoloration. The third type of cover is relatively easily removed but while in operation the forces exerted by the cords tend to cause a cover to pucker due to the non-uniform pulling forces exerted by the engaged cords. This puckering renders these types of covers relatively unsightly. If the pucker extends to the top of the step, a safety hazard exists as it may cause a user to trip.
Except for the first above-described cover, the other two types of covers do not lend themselves for use where the step is supported at the midpoint by a riser. That is, the presence of a riser extending for essentially the full width of the step essentially precludes wrapping the cover about the front and rear edges and attaching them to the bottom of the step. Thus, steps supported by a riser at or close to the midpoint of the step limits the use of a cover to the top surface of the step. Where such steps are of metal, attachment on a permanent or semi-permanent basis of a cover creates significant issues relating to attachment and covers are unlikely to be used.
The present invention is directed to a cover or rug for a step that extends across the top of the step with the longitudinal ends thereof extending along the front and back sides and partially onto the bottom of the step. In the event the step is supported by a riser at the midpoint thereof, the front and rear edges of the cover are split to extend along the bottom of the step on each side of the riser. The end of each front and rear edge of the cover supports a rod within a sleeve. A plurality of apertures are formed in each front and rear edge adjacent the corresponding rod. The front and rear edges of the cover are drawn toward one another to secure the cover in place by conventional plastic tie wraps engaging pairs of holes in the opposing ends of the cover. The tie wraps bear against the respective rods and thereby exert a pulling force along the full length of each corresponding opposed end. By tightening the tie wraps, sufficient friction exists between the cover and the step to prevent sliding movement of the cover along the step. Replacement of a cover is a simple matter of severing the tie wraps to disengage the old cover and removing it. The replacement cover is secured in place with new tie wraps.
It is therefore a primary object of the present invention to provide a detachably attached cover that extends along the top, sides and onto the bottom of a step.
Another object of the present invention is to provide a cover that wraps along the top and sides of a step and applying a uniform force exerted along opposing ends of the cover to draw them toward one another on the bottom of the step and retain the cover in place.
Still another object of the present invention is to provide a wraparound cover for a step having a rod disposed along each end of the cover beneath the step and drawn toward each other by multiple tie wraps engaging the rods.
A further object of the present invention is to provide a rod at each end of a wraparound cover for a step and tie wraps urging the rods toward one another to establish a uniform force along the length and width of the cover to retain it in place.
A yet further object of the present invention is to provide a rod at each end of a wraparound step cover for detachably attaching the rods to one another with tie wraps.
A yet further object of the present invention is to provide a wraparound cover having front and back split ends extending beneath a step to accommodate the presence of a riser and the use of tie wraps to engage rods at opposed paired ends on either side of the riser to draw the paired ends toward one another and secure the wraparound cover in place.
A still further object of the present invention is to provide a wraparound cover for a step supported in part by a centrally located riser by splitting the opposed ends of the wraparound cover into two paired ends and drawing the ends of each pair of ends toward one another by tie wraps engaging rods disposed at each end of each pair of ends.
A yet further object of the present invention is to provide a uniform force extending along the length of the ends of a wraparound cover disposed at the bottom of the step.
A yet further object of the present invention is to provide a method for drawing the ends of a wraparound cover at the bottom of a step with tie wraps engaging a rod disposed at each of the ends to exert a uniform force along the length of each of the ends.
These and other objects of the present invention will become apparent to those skilled in the art as the description thereof proceeds.
The present invention will be described with greater specificity and clarity with reference to the following drawings, in which:
Referring to
The underside of each wraparound cover is illustrated in
A rod 60 is disposed within a sleeve 62 of bifurcated end 42. Apertures or holes 64, 66 penetrate sleeve 62 essentially adjacent the location of rod 60. A similar rod (60), sleeve (62) and holes (64,66) are disposed in each of remaining bifurcated ends 44, 46 and 48. For purposes of simplicity of numbering, these elements have common identifying numbers.
Each cover is retained in place by securing the paired bifurcated ends with one another. A conventional tie wrap 70 is looped through opposing holes 64. Another tie wrap 72 is looped through holes 66. Each of these tie wraps is drawn tightly to bring bifurcated ends toward one another. The forces exerted by tie wraps 70, 72 bear upon respective rods 60. These rods, being in their respective sleeve 62, translate the force urged by the tie wraps to essentially the full width of each bifurcated end. Thereby, there is no concentration of forces, such as would be present were grommets or the like, used and engaged by similar tie wraps. Furthermore, as each tie wrap can be tightened to a selective degree, the wraparound cover is firmly and essentially immovably attached to its corresponding step.
Referring jointly to
As may be noted by inspection of modules 10 and 90, the use of the rods in sleeves at the front and rear ends of the wraparound cover apply a uniform force exerted by the tie wraps extending uniformly along the lengths of the front and rear ends of the wraparound cover. Thus, there is no concentration of forces, such as would be the case with use of grommets, or holes engaged by tie wraps or cords. Similarly, were snaps or other localized attachment means used to draw the front and rear ends toward one another, there would be a concentration of forces resulting in puckering and unsightliness of the wraparound cover.
