`entire device in its assembled form constitutes
`a high chair. It is understood, however, that in
`stead of the chair ll any other suitable device
`may be supported by the superstructure H5.
`The understructure comprises two inverted U
`shaped leg members i9 and is, member [8 con
`sisting of front leg 20, rear leg 2! and lateral
`connecting bar 22, and leg member 19 consists
`of front leg 23, rear leg 25 and lateral connect
`ing bar 25. Attached to the inner'surfaces of
`leg members [3 and 19 are the rail members gen
`erally designated 25 and 21, containing the paral
`lel rails 28 and 29 respectively, joined by the
`rear bar 35, the forward portions of said rail
`members containing the hand gripping loops 3|
`and 32, respectively. Loop 31 contains the
`downwardly extending arcuate section 33 and the
`rearwardly extending lower section 34; and loop
`32 contains the downwardly extending arcuate
`section 35 and the rearwardly extending section
`35. In the preferred structure illustrated, the
`rails 28 and 29 are connected to the lateral bars
`22 and 25 of the leg members by strips 37 and
`38 either soldered, welded or otherwise attached
`thereto; and it is also preferred that the loops
`3: and 32 be attached to legs 29 and 23 respec
`tively, at their intersections.
`Pivotly mounted at 39 and 39a. of the rails 28
`and 29, and disposed therebetween, is the table
`40, the rear connecting bar 39 of the rails be
`ing disposed behind the table. In the form of
`our invention illustrated, the upper surface 4|
`of the table (Figure 10) contains an ordinary
`?at surface which may be used for feeding or
`other purposes; and the opposite side of the
`table 42 (Figure 7) contains a slate wall or other
`writing surface. As will be noted, the table is
`revolvable into three operative positions, Figures
`'7 and 10 showing two reverse positions thereof,
`and Figure 11 showing an inclined position.
`The table is maintained in any of its three
`said operative positions by means of releasable
`One corner 43 of the table con
`’ locking means.
`tains an apertured portion 54 within which is
`slidably mounted the elongated retractable ele
`ment 45 carrying the knob 45 for manual ma
`nipulation; and at the rear of element 45 is the
`spring 47 normally urging element 45 outward
`ly so that it may enter one of three apertured
`portions in the adjacent rail member 25. Two
`50
`of said apertures are on the rail 26, the front
`one being 48 and the rear one 4-9; and the third
`of said apertures 56 is disposed on the lower rear
`wardly extending section 34. The arrangement
`is hence such that upon a manual retraction of
`element 45, the table 45 may be swung into any
`one of the three positions, the table being releas
`ably locked in one of said three apertures 48, 49
`or 59.
`It is preferred that the foremost portions of
`loops 3! and 32 be disposed forwardly of the front
`edge 5! of the table, so as to facilitate grasping
`said loops when it is desired to move the struc
`ture, or to hold it while the table is being op
`eratably manipulated. It is also preferred. that
`the thickness of table 49 be less than the di
`ameters of the rails 28 and 29, and that the
`table be mounted centrally upon said .bars so
`that the uppermost surfaces of the rails will be
`above the opposite surfaces of the table when it
`is in either of its two horizontal positions. As
`will more clearly hereinafter appear, this will
`keep the table at all times spaced from the super
`structure when it is operatively mounted upon
`the rails (Figure 3), there being a space 52 be

`tween the table and the base of the superstruc
`ture. It is also preferred that the lateral bars
`22 and 25 of the leg members be disposed above
`the rails 28 and 29, thereby providing lateral sup
`ports against which the superstructure can slid
`ably move when being operatively. assembled
`thereon, as will hereinafter appear.
`The superstructure comprises the base por
`tion 53 consisting of the two side bars- 54 and
`55 connected together by the rear connecting
`bar 56 (Figures 1, 2 and 3), the forward portions
`of the side bars 54 and 55 being respectively
`connected to hand gripping portions 51a. and 51,
`these respectively comprising the loops 58 and
`59 and the upper inwardly extending supports
`69 and 6|, the latter being preferably horizon
`tal and disposed inwardly relative to the side
`bars 54 and 55. ‘The said supports 60 and 61
`are adapted to support some upper article, such
`as the chair H, by suitable fasteners.
`The lateral bars 22 and 25 of the leg members
`have mounted thereon two inwardly extending
`guiding elements 62 and 63 respectively, these
`being preferably, although not necessarily, cylin- '
`drical members, said members being spaced
`above the respective rails 28 and 29. The dis
`tance between element 62 and rail 28, and be
`tween element 63 and rail 29, is preferably such
`as to permit the base bars 54 and 55 of the super
`structure to slidably move therebetween, as
`clearly shown in Figure 3. Hence, in operative
`ly placing the superstructure into interlocking
`engagement with the understructure, the side
`bars 54 and 55 are placed upon rails 28 and 23
`at a point forwardly of the guiding elements 62
`and 63, and slid rearwardly into interlocking en
`gagement.
`The device is further provided with stop means
`for stopping the forward or rearward movement
`of the superstructure upon the understructure,
`and releasably locking it in said predetermined
`assembled position. ' Said stop means, in the
`preferred form illustrated, comprises (see Fig
`ures 4, 5 and 6) an elongated element 64 extend
`ing through the rail 28 and proportioned to enter
`the aperture 65 in the base bar 54. Disposed
`below and in abutting engagement with the head
`of element 64 is the spring 66 positioned within
`the rail_28, the lower portion of element 64 hav
`ing ?xably mounted thereon the cam knob 61
`containing thereon the cam surface 68. In the
`position shown in Figure 5, the highest point of
`the cam surface is in engagement with the under
`side of rail 28, thereby causing a downward re
`traction of element 64 and its withdrawal from
`aperture 65. In this position, the superstructure
`can readily be made to slide over the rail. Upon
`a rotation of knob 61 through an angle of 90°,
`the lowest portion of the cam surface 68 comes
`into engagement with the under side of rail 29,
`thereby permitting the locking element 64 to
`enter the aperture 65, and effect an interlocking
`of the rail 28 and bar 54. When this occurs it
`is obvious that the superstructure cannot move
`relative to the understructure unless the inter
`locking engagement is released by operatively
`manipulating the knob 61.
`The arrangement is hence such that the hands
`are left free to grasp the loops 58 and 59 of the
`superstructure and manipulate it slidably upon
`the understructure, since the cam knob 61 will
`frictionally maintain itself in its unlocked posi
`tion after it had been moved thereto.
`It will also be observed'that the loops 3| and
`32 of the understructure and the loops 58 and 59
