Abstract: A toothbrush head having elastomeric oral hygiene parts in the form of elastomeric strips aligned non-perpendicular to the length direction of the head. Preferably adjacent pairs of strips are linked to form a strip of “V” (32A, 32B) cross section. Preferably the head comprises flexibly linked segments (14, 15) and is flexibly linked to the toothbrush handle.

Abstract: A changeable frame for supporting flat surfaced items such as pictures, posters, placards or the like, is provided, which includes a plurality of frame border strips which collectively form the border of the changeable frame. Each frame border strip includes a base profile member and a cover member movable between a closed item retaining position in which an item is retained by the changeable frame and the cover member partially extends over and exerts a resilient biasing force against the item and an open position. Each frame border strip also includes a pivot arrangement for pivotally mounting the base profile member and the cover member to one another. The pivot arrangement includes a fulcrum formed on the base profile member which is contacted by a counter stop surface formed on the cover member to prevent an overpivot movement of the cover member beyond its predetermined pivot travel.

Abstract: A frame border corner connecting device for interconnecting a pair of selectively lockable frame border strips of a changeable frame so as to thereby form a corner of the changeable frame is provided. The frame border corner connecting device includes a base element having respective sides to which each one of the frame border strips is securable. The frame border corner connecting device also includes a corner cover element movably mounted to the base element for movement between an open position, in which the corner cover element is clear of the path of movement of an item being moved selectively into or out of the changeable frame, and a closed position in which the corner cover element extends at least partially into the path of movement of the item.
