Patent number: 6698721Abstract: A shock-absorbing carpet kicker for positioning and stretching carpet is disclosed. The carpet kicker includes an engaging head with forwardly-inclined pins for engaging carpet materials on a floor, a shaft connected to the engaging head and extending therefrom, a cushioned pad facing away from the engaging head and connected to the shaft a distance away from the engaging head, and a shock-absorbing device connected to the shaft and interposed between the engaging head and the cushioned pad. The shock-absorbing device comprises a resilient member preloaded against a collapsible tension member, whereby kicks to the cushioned pad are transmitted through the shock-absorbing device to the engaging head. The preloaded tension member permits a portion of the energy of each kick to be transmitted directly to the engaging head, while the resilient member absorbs excess energy of the kick.Type: GrantFiled: December 6, 2001Date of Patent: March 2, 2004Inventor: John H. Martin
