Claim:
A portable ladder support device for supporting a ladder positioned temporarily thereon, said ladder comprises two side rails connected by spaced rungs wherein the bottom ends of said two side rails are spaced apart within a range predetermined for said portable ladder support device, said portable ladder support device is capable of supporting said ladder by supporting the bottom ends of said two side rails, said portable ladder support device comprises at least one handling member, a plurality of support elements, and a frame comprising a fixating means, a release means, a plurality of guides for guiding movements of the support elements along predetermined trajectories, and a ladder support area for temporary positioning said ladder thereon by said bottom ends, each of said plurality of support elements is longitudinal, said fixating means is for preventing said movements simultaneously when engaged and for allowing said movements simultaneously when disengaged, said release means is for disengaging said fixating means when deployed by a user and for engaging said fixating means when disengaged by a user, said portable ladder support device is deployed when said ladder support area is capable of supporting said bottom ends, said ladder support area is capable of supporting said bottom ends when it is oriented at a predetermined angle and all of the support elements touch a solid surface and said release means is disengaged, said at least one handling member is for carrying said portable ladder support device and for orienting said ladder support area at said predetermined angle by at least one user regardless of positions of said plurality of support elements about said solid surface, said portable ladder support device also comprises a means for supporting orientation of the deployed portable ladder support device without said ladder when unattended, said portable ladder support device further comprises a predetermined number of restricting members for preventing movement of said bottom ends when said ladder is finally positioned on the deployed portable ladder support device, whereby the deployment of said portable ladder support device is achievable quickly on solid surfaces of various profiles since moving individually each of the support elements is unnecessary when a force is applied simultaneously to said plurality of support elements and said release means is deployed.
