초록 ▼

A collapsible volume frame, when erected, presents in each of two opposite side elevations a side space frame defined by four points which if joined would form a quadrilateral; and presents further space frames in the four other aspects. The side space frames are braced by at least one frame element disposed transversely and articulated to them in a triangulated manner. Releasable means resist collapse of the volume frame. These side and further space frames are foldable so that the volume frame when collapsed forms a bundle.

대표청구항 ▼

A volume frame foldable in two dimensions mutually at right angles, comprising, when extended, a pair of opposite sides of corresponding form, each such side comprising elongate elements and a first plurality of pivot connection means, the elements of each such side including at least an upright front leg, an element which is an upright back leg, and a rigid element which joins the front leg to the back leg through said pivot connection means, said pivot connection means being a pair spaced along said rigid element and disposed at two corners of a theoretical quadrilateral of which said front leg and said back leg are opposite sides, each pivot connection means of said pair affording a horizontal axis directed from side to side of the volume frame, thereby enabling folding of the frame in one of said dimensions by pivoting of each said front leg about one horizontal axis and pivoting of each said back leg about another horizontal axis in the back to front sense of the frame with concurrent mutual approach of said front leg, said back leg and said rigid element in each said side frame, the frame further comprising: at least one collapsible X frame and a second plurality of pivot connection means each having two degrees of pivotal freedom including pivotal freedom about a horizontal axis directed from side to side of the volume frame, said second plurality of pivot connection means being spaced in the side frames from said first plurality of pivot connection means, which X frame lies in a plane extending in the lateral sense of the volume frame and inclined to a front plane and a back plane which contain, respectively, each said front leg and each said back leg, said X frame having a pair of lower ends and a pair of upper ends, of which X frame one such lower end and one such upper end are each pivotally connected by a respective pivot connection means of said second plurality thereof to one of said opposite sides of the volume frame whereas the other such lower end and the other such upper end are each pivotally connected by a respective pivot connection means of said second plurality thereof to the other of said opposite sides of the volume frame, thereby enabling folding of the frame in the other of said dimensions by collapse of said X frame; and at least one tie means having two ends of limited separability by which ends said tie means are connected in the volume frame in triangulating relationship with said X frame for supporting the volume frame when extended. A volume frame as claimed in claim 1 in which each of said opposite sides comprises four elongate elements joined serially by said first plurality of pivot connection means to form a closed quadrilateral space frame including the front leg, the back leg, the said rigid element and a second rigid element extending generally parallel to, but spaced from, said rigid element. A volume frame as claimed in claim 5 in which ground wheels are mOunted thereon and adapt the volume frame for use as the frame of a wheel chair, a fabric seat extends between said pair of opposite sides and is attached thereto, each said back leg has an upward extension, and a fabric back support extends between each said upward extension and is attached thereto.
