TRANSFORDIED INTO ~ . A ABLE ‘ Paul Denormandie, Paris, France Application August 1, 1936, Serial No. 93,903 In Luxemburg August 3, 1935 1 Claim. 7 It‘ is known that persons who want to make a picnic make use of folding tables on the one hand, and on the other hand of suitable cases or boxes which may even be combined with the tables, but UK which have the disadvantage that they can be unfolded so as to be set as tables only after the articles normally contained in the case or box have been removed therefrom. This involves a loss of time and even a risk of injury of said 10 articles. On the other hand, it is also known that the work of persons having to check up certain appa ratus or circuits in shops or factories is generally awkward, because these persons often do not ?nd any place where they could put their measure ment apparatus, which they carry in a case which is both cumbersome and heavy.~ The object of the present invention is to pro vide a case or box for carrying objects, adapted 20 to constitute a rolling table permitting the easy use of the tools or apparatus, or the show of the goods carried in said case or box. This case is constituted by a body forming a receptacle, a lid forming at the same time the 25 upper part of the table, four jointed feet hidden in the case when the latter is closed but adapted to support the lid when the table is unfolded, and sets of wheels or rollers carried by the feet and brought into active position only when said feet 30 are pivoted so that the case is transformed into a c-a C.l table. In a particular embodiment of the invention these feet or legs are connected by pairs by two cross members, and they are ?tted, at their lower ends, with rollers or shoes which permit of easily moving the table. These legs are adapted to pivot through an angle of 90° about two horizontal spindles rigidly ?xed to the body of the case. In one of their extreme positions, these legs are fully 40 enclosed in the case, owing to the special ar rangement of the parts, which enables a pair of legs and their cross member to fit between the two other legs and under the cross member cor responding thereto. In the other extreme posi 45 tion, these legs are disposed vertically, being then rigidly maintained by means of a latch or any other ?xation means. The movement which corresponds to the rising of the upper ends of the legs, causes their lower ends to project from the 50 base of the case, which is thus lifted above the ground. The lid is ?xed to the longer of the two cross members, through hinges permitting a ‘rotation through an angle of 270°. When the legs have been ?xed in their vertical position, the lid is piv (01. 190-11) oted about its hinge so as to be brought into hor izontal position, the upper face ‘being then the under face of the lid when the latter is applied against the case in the closed position. The end of the lid opposed to the hinge lies upon the other cross-member, to which it is rigidly ?xed by means of screws or any other means ensuring the rigidity of the whole. These and other features of the present inven tion will result from the following detailed de scription of a speci?c embodiment thereof. A preferred embodiment of the present inven tion will be hereinafter described, with reference to the accompanying drawing, given merely by way of example, and in which: Fig. 1 is a perspective view of a case accord 15 ing to the invention, shown in the unfolded posi tion, in which it acts as a table; Fig. 2 is a sectional view of the case in the folded position; 20 Fig. 3 is a sectional view on the line III-III of Fig. 1. ' The body I of the case, made of any suitable material, is ?tted with two horizontal spindles 2 about which are pivoted the legs 3 of the table. Said legs are so shaped, as shown by Fig. 3, that they can pivot in the direction of arrows F with out being interfered with by the ends 4 of the case. Between partitions 5 extends the space 6 for the articles to be carried by the case. 7 30 In order to ensure the rigidity of the whole when the case is used as a table, legs 3a and 3b are connected together by cross-members Illa and mo. In the closed position, cross members Illa and 10b bear upon the chamfered portions Ha 35 and llb provided in partitions 5, at the ends thereof. At the lower ends of legs 3a, 31), close to their pivots 2, there are ?tted rollers or shoes l2 ow ing to which the case, once transformed into a 40 table, can be displaced without difficulty. In order to keep legs 3a, 3b in vertical posi tion, when the case is used as a table, I provide hooks l3. Finally, the case is ?tted with holders l4 per mitting to carry it easily. This device will operate in the following man ner: The articles to be carried being placed in the free space 6, it su?ices to grasp lid 9 with the hand, and to pull it upwardly, whereby legs 3a are caused to pivot about their spindle 2. When the legs 3a have been brought into the position shown by Fig. 1, the lid 9 is pivoted about its hinge 8, in a direction opposed to that in which 55. 2 2,110,791 legs 30; have been precedingly turned. It then su?ices to pivot legs 31:) about their spindle 2, so that they can support the other end of the lid, opposed to that hinged at 8 to legs 3a. The objects carried in space 6 can then be a rolling table, comprising a rigid body portion and a movable top portion, four lever arms nor mally hidden within the case, each located at a corner of the case and each pivotally connected removed so as to be put on the table. It should be noted that all the movable ele adjacent one end to one of the opposite lateral walls of the case for movement from a hidden position extending above the top of the case, ments of the case are pivoted and kept in either openings at the bottom of the case, the said of their two positions without requiring assem~ 10 bling members the absence of which might im pair the strength of the whole. pivots being located so that said ends of said lever arms will project through the bottom of In a general manner, while I have, in the above description, disclosed what I deem to be practi cal and e?ioient embodiments of the present in 15 vention, it should be well understood that I do not wish to be limited thereto as there might be changes made in the arrangement, disposition and form of the parts without departing from the principle of the present invention as compre 20 hended within the, scope of the accompanying claim. What I claim is: A portable case adapted to be transformed into the case in said latter position, transverse spac ing bars connecting the other ends of the oppo site lever arms at each end of the case, a hinged connection provided between one edge of the movable top portion and one of said spacing bars, 15 rollers normally hidden within the case mounted upon the lower portion of said levers, said rollers upon movement of the levers to extended posi tion automatically lifting the same above the 20 ?oor level.
