Abstract: A shock absorbing hand grip comprises an inner elongated resilient tubular wall member adapted to slidably receive a supporting structure and an outer concentric resilient elongated tubular wall member spaced from the inner tubular wall member. A plurality of flexible spacer members are disposed between the inner and outer tubular wall members having a first end attached to the inner tubular wall member and a second end attached to the outer tubular wall member. The flexible spacer members are disposed between the inner and outer tubular wall members at an angle to the axial plane of said tubular members so as to create a region of bending flexure for the spacer member between the inner and outer tubular walls such that shock forces applied to one tubular wall member will cause a bending flexure of the spacer members whereby such shock forces are substantially completely displaced in a non-radial direction to the other tubular wall member.

Abstract: A lawn mower is described having a high collection efficiency. This is accomplished by constructing a housing having a toroidally-shaped skirt defining the interior space in which the blade rotates in a horizontal plane. The interior space has a generally circular cross-section, the radius of which gradually increases toward a region of maximum radius between upper and lower portions of the housings. The blade is positioned to rotate in the lower portion of the housing and a discharge port is positioned to encompass the region of maximum radius.
