with reference to the drawings , a support structure 10 in accordance with the invention is shown in fig1 with an illustrative animal a cradled between panels 11 - 1 and 11 - 2 in position for being examined or treated by a veterinarian v . the support structure 10 includes side panels 12 - 1 and 12 - 2 which are hinged to the respective cradle members 11 - 1 and 11 - 2 . the side panels 12 - 1 and 12 - 2 are further hinged to respective members 13 - 1 and 13 - 2 of a base member 13 . as indicated in fig1 the base 13 is desirably in two sections 13 - 1 and 13 - 2 which meet at the hinge position 11 - h at the junction of the cradle members 11 - 1 and 11 - 2 . the panels 13 - 1 , 12 - 1 , 11 - 1 , 11 - 2 , 12 - 2 and 13 - 2 are desirably fabricated from a single sheet of material , with the hinges between the panels formed in the adjoining material . where the panels are made from pressboard , the hinges 11 - h , 12 - h2 , 12 - h1 , 13 - h1 and 13 - h2 are formed by scoring . where the panels are of plastic , the hinges are formed by molding or die pressure . the ends of the base panels 13 - 1 and 13 - 2 are advantageously joined by an adhesive strip 14 leaving a notch 13 - n between the ends of the base panels 13 - 1 and 13 - 2 . the notch 13 - n receives the hinge 11 - h and helps stabilize the support structure 10 when it is in its support position . it will be appreciated that the tape strip 14 may be positioned elsewhere on the structure and that a hinge between the members 13 - 1 and 13 - 2 may be included with proportions to stabilize the hinge 11 - h in the manner previously described . in that event , the adhesive strip 14 may be included at any of the other hinge positions , for example in place of hinge 13 - h1 , 12 - h1 , 12 - h2 or 13 - h2 . various structural characteristics of the support 10 are illustrated in fig2 where the hinge 11 - h , with the animal a removed , has been elevated in the direction indicated by the arrow r until the cradle members 11 - 1 and 11 - 2 are parallel with the base members 13 - 1 and 13 - 2 . in this position it is seen that each of the cradle members 11 - 1 and 11 - 2 has a width w which is greater than that of the width v of each of the base members 13 - 1 and 13 - 2 . in addition , the widths u of the side panels 12 - 1 and 12 - 2 are less than the widths v and w . in an illustrative embodiment of the invention , the widths u , v and w are in the ratio of 51 / 4 to 6 to 7 . in any event , the parts are proportioned so that the cradle members 11 - 1 and 11 - 2 form an angle l in fig1 of about 90 °. to collapse the structure 10 , one procedure is illustrated in fig3 . the structure 10 is gripped on opposite sides in the vicinity of each of the hinges 13 - h1 and 13 - h2 and the associated panels 12 - 1 and 12 - 2 are elevated causing a reduction in the angle l &# 39 ; between the cradle members 11 - 1 and 11 - 2 . there is simultaneously an approach of the base panels 13 - 1 and 13 - 2 as well as side panels 12 - 1 and 12 - 2 towards the cradle panels 11 - 1 and 11 - 2 . when the panels 12 - 1 , 12 - 2 , 13 - 1 and 13 - 2 are collapsed against the cradle members 11 - 1 and 11 - 2 the result is as indicated in fig4 c and the structure is ready for storage . an alternative technique for collapsing the structure 10 is illustrated in fig4 a . the cradle members 11 - 1 and 11 - 2 are drawn together , reducing the angle l &# 34 ; to zero and causing the base and side panels to form a rhombic cross section . when the partially collapsed structure in fig4 a is allowed to lean on its side as shown in fig4 b , the cradle members 11 - 1 and 11 - 2 , together with the side panels 12 - 1 and 12 - 2 fall in the direction indicated by the arrow w resulting in the collapsed structure as illustrated in fig4 c . while various aspects of the invention have been set forth by the drawings and specification , it is to be understood that the foregoing detailed description is for illustration only and that various changes in parts , as well as the substitution of equivalent constituents for those shown and described may be made without departing from the spirit and scope of the invention as set forth in the appended claims .
a compact collapsible support for animals formed by a set of hinged members which can be arranged to form a cradle that is maintained by the weight of the animal and is thereafter collapsed when the animal has been removed and the support is to be stored .
