A bumper assembly 100 includes an elongate shell 102 formed of a wooden material and an elongate base 104. The elongate shell 102 has an inner surface, an outer surface, a first shell edge, and a first flange protruding from the first shell edge in a direction toward the inner surface of the elongate shell. The elongate base 104 includes a base body including a first base edge and a first latching element extending from the first base edge of the base body, the first latching element having a first inclined outer surface and a first shoulder. The elongate base 104 is configured for insertion into the elongate shell 102 with the first flange engaging the first shoulder of the first latching element.
摘要:
Methods and devices for thermoforming rigid plastic profiles into desired angular configurations are disclosed. The invention involves heating a rigid, plastic, partially-sectioned profile (16) until the profile becomes malleable; and moving at least one of a first mold (12), having a shape substantially corresponding to the desired angular configuration, and a second mold (22), having an angular shape substantially corresponding to and mating with the first mold, into juxtaposition with the other molds such that a zone (14) of the profile (16) is positioned therebetween; and applying a selected pressure to the zone of the profile with the first and the second molds for selected duration until the profile is thermoformed into the desired angular configuration.
摘要:
A shopping cart station (10) has free-standing first and second hollow wall members (1,3) at least partially filled with a ballast material. A connecting element (5) couples the first and second hollow wall members (1,3) together. The cart station (10) can be easily moved and secured by emptying the hollow wall elements (1,3) of the ballast material, repositioning the cart station (10), and refilling the wall members with ballast.
