Abstract
A device and method for improving the mobility of a ladder. The device includes slide pads that attach to the bottom ends of a ladder's rails. In this manner, the slide pads are interposed between the bottom of the ladder rails and the ground when the ladder is erected. The bottom surface of the slide pads have a lower coefficient of friction than do the bottom ends of the ladder rails. Accordingly, the presence of the slide pads at the bottom of the ladder rails makes the ladder rails easier to slide over the ground.
Claims8
An assembly comprising:
- a ladder having at least two ladder rails that support the ladder in a standing position;
- and
- slide pads attached to at least some of said ladder rails so that said slide pads are disposed under said at least some of said ladder rails when said ladder is in said standing position, each of said slide pads having a base, a vertical support that extends upwardly from said base, and flexible arms that extends from vertical support, wherein said vertical support and said flexible arms form a receptacle structure that receives and engages one of said ladder rails of said ladder.
An assembly comprising:
- a ladder having at least two ladder rails that support the ladder in a standing position;
- slide pads attached to at least some of said ladder rails so that said slide pads are disposed under said at least some of said ladder rails when said ladder is in said standing position, each of said slide pads having a base and a receptacle structure that extends upwardly from said base, wherein said receptacle structure includes a tubular elastic band that is adapted to surround a portion of one of said ladder rails, thereby enabling said receptacle structure to receive and engage a ladder rail.
An assembly comprising:
- a ladder having at least two ladder rails that support the ladder in a standing position;
- and
- slide pads attached to at least some of said ladder rails so that said slide pads are disposed under said at least some of said ladder rails when said ladder is in said standing position, each of said slide pads having a base and fingers that extend upwardly from said base, wherein said fingers form a receptacle structure that receives and engages one of said ladder rails of said ladder and there is at least one strap for biasing said fingers toward each other.
