(Cl. 311-453) This invention relates to an improved folding table structure, and while the invention may be adapted to many different uses, it is particularly useful in and has been specifically designed for 5 “ the care of infants, providing improved means for effecting the elevated support of an infant’s bath tub or bathing receptacle and associated means upon which an infant 'may be placed for dressing 10 and other attention demanding services. Those having to do» with the care of infants are frequently obliged to employ makeshift articles of furniture in the bathing and dressing of infants and> other necessary duties. Sometimes a bathing receptacle is placed on an ordinary table, or in other instances folding card tables are utilized, so that it will not be necessary for the attendant to stoop over or to assume a kneeling position in performing various duties affecting the Welfare of the infant. 20 It is therefore a cardinal object of the present invention to provide an improved foldable or co1 lapsible supporting table which may be quickly and easily erected to assume an active extended position, and wherein the table includes, when ex 25 tended, a horizontally supported shelf adapted for the reception of an infant’s bathing receptacle, means being associated with the shelf to main tain the same in a fixed horizontal plane and to limit the extensibility of the frame structure of the 30 table, to the end of providing a secure,.stable and substantial construction on which the bathing re ceptacle may be readily placed and supportedy in an elevated plane and also one which, when not in use, may be compactly folded to occupy but a 35 minimum of storage space. Another object of the invention resides in pro viding the folding table with a t`op frame carrying a stretched fabric body, the said top frame when in use being disposed over the receptacle support 40 ing shelf for support in a horizontal plane in con nection with the folding frame structure of the table, so that an infant may be placed on the fabric body and comfortably and securely sup ported when receiving various attentions. A further object resides in the provision v of means for effecting the support of the top frame in a substantially vertical position when the same is not -in actual use or during the period when a bathing receptacle is supported on the shelf nor 50 mally beneath the same. Other objects of the invention reside in the pro vision of a folding table having the general fea tures and characteristics above set forth and one which will be light in Weight and simple and in 55 expensive in design. For a further understanding of the invention, reference is to be had to the following description and the accompanying drawings, wherein: Fig. l is a perspective View of a folding table structure formed in accordance with the present ' invention and illustrated in its extended, set up or active position; Fig. 2 is an end elevation of the table structure, the inactive position of the top frame being dis closed by dotted lines; 10 Fig: 3 is an enlarged horizontal transverse sec tional view on the line III-III of Fig. 2, disclos ing the folding leg members and the adjoining portions of the receptacle supporting shelf; Fig. 4 is a detail vertical sectional view taken 15 on the plane indicated by the line IV--IV of Fig. 2 and showing one of the shelf-supporting studs; Fig. 5 is a detail vertical sectional view on the plane indicated by the line V-V of Fig. 3 and showing one of the links employed for guiding 20 the swinging movements of the receptacle sup~ porting shelf and for limiting the extensibility of the pivoted leg members of the table; Fig. 6 is a similar View disclosing the shelf and the leg members in their folded or collapsed posi tions; ~ Fig. 7 is a detail vertical sectional view dis closing the top supporting frame of the table in its inactive position; Fig. 8 is a detail edge elevation of the slidable 30 mounting for the top supporting frame; Fig. 9 is an end elevation disclosing the top sup porting frame in an inclined or half elevated position; Fig. l0 is a perspective view of the member for retaining the top frame in the position disclosed in Fig. 9. My improved foldable nursery table comprises end frames, each of which consists of a pair of bars l pivotally united as at 2 at their points of intersection. The lower ends of the bars of said end frames are united and strengthened by means of longitudinally extending connecting braces 3, while the upper ends of said bars are similarly united by a pair of longitudinally extending con 45 necting rods li. By this construction intersecting substantially rectangular frames are produced of rigid construction which are pivotally united at their points of intersection. ‘ Pivoted as at 5 to one set only of the bars I, be low the upper ends of the latter, is a receptacle supporting shelf 6, which, when actively posi tioned as shown in Figs. l and 2, occupies a horizontal plane, but when inactively positioned as shown in Fig. 6, depends from the pivots 5 in 55 2 2,113,689 a substantially vertical plane. To support the shelf in its active horizontal position, the leg members I, opposed to the leg members With which the shelf is pivotally connected, carry, as shown in Fig. 4, inwardly projecting metallic studs 'I. These studs are so arranged that they underlie the free edge portions of the shelf 6, to prevent the shelf from sii/inging downwardly when disposed in a horizontal plane. To lock the 10 shelf Ii in its active position, and to prevent ex tallic plates I4 carrying pivoted bails I5, and these bails are adapted to receive tapes I6 which are connected with the under side of the frame I2, the bails I5 and the tapes I6 serving to guide the top frame or shelf when it is being moved from one position to another. If desired, a handle I'I may be connected with one of the longitudinal edges of the top shelf or frame, as in Fig. 1, so that it may be conveniently grasped to facilitate its actuation. 10 cessive spreading movement of the leg members As shown in Fig. 9, the top frame or shelf may of the end frames, the studs 'I pivotally carry be tilted to assume an angular position with re metallic locking links 8, arranged at each of the spect to both horizontal and vertical planes and longitudinal ends of the shelf. The outer ends of retained in such a position of adjustment by the 15 these links are, as shown in Figs. 5 and 6, pro-~ use of one or more supporting rods I8. The lat vided with bayonet slots 9 which receive the ter has its opposite ends offset or laterally bent shank portions of headed pins I D carried by and ' as at I9 to engage with openings provided in one projecting longitudinally from the side edges of of the bars I and the frame I2.
