Application April 6, 1956, Serial No. 576,633 2 Claims. c1. 15s 143) This invention generally relates to a high chair for small children and more particularly provides a foldable high chair which may be collapsed to a compact condition for easy transportation thereof.
The primary object of the present invention is to provide a high chair which may be folded to a compact condition for ease of transportation or storage and which may be unfolded for use and which includes wheels to facilitate movement of the high chair to a desired position.
Yet another important object of the present invention is to provide a high chair constructed preferably of tubular metallic material that is relatively light weight but yet suificiently rigid to provide long life and dependability to the high chair.
Other objects of the present invention will reside in simplicity of construction, ease of adjustment of the tray, ease of folding and unfolding, adaptation for its particular purposes and its relatively inexpensive manufacturing cost.
These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure l is a persepective view of the high chair of the present invention;
Figure 2 is a detailed view illustrating the pivotal interconnection between the legs of the frame members;
Figure 3 is a detailed perspective view of one of the hinge joints in the support legs;
Figure 4 is a detailed view similar to Figure 3 illustrating the sections of the legs folded to a position alongside each other;
Figure 5 is a fragmental detailed sectional view illustrating the manner of attaching the tray to the support frame and also the support members for the support frame;
Figure 6 is a side elevational view of the high chair of the present invention;
Figure 7 is a perspective view of the high chair illustrating the device in partially folded condition; and
Figure 8 is a perspective view illustrating the high chair in its fully folded position.
Referring now specifically to the drawings, the numeral 10 generally designates the high chair of the present invention including a pair of frame members 12 and 14 which includes at its upper end a support frame 16, a tray generally designated by the numeral 18 and a seat and back assembly generally designated by the numeral 20.
Each of the frame members 12 and 14 is in the form of an inverted U-shaped member having a bight portion 22 and a pair of parallel legs 24 and 26 which terminate in free ends having an interconnecting rod 28 with wheels 30 journaled thereon wherein the wheels 30 at the lower end of each of the legs 24 and 26 on each of the frame members 12 and 14 will movably support the high chair 10 on a supporting surface.
Hingedly interconnecting the legs 24 and 26 of the frame members 12 and 14, respectively, is a hinge rod 32 extending through adjacent legs 24 as illustrated in Fig. ure 2 and provided with a spacer 34 for retaining the legs 24 adjacent each other and for retaining the legs 26 adjacent each other for facilitating the use of a stop plate 36 having oppositely disposed channel-shaped portions 38 and 40 on the oppoiste ends thereof wherein the channel shaped portions 38 and 40 are inclined in such a manner to receive the adjacent legs 24 when they are in their crossed position thereby limiting the pivotal movement of the adjacent legs 24 and also limiting the relative pivotal movement between the frame members 12 and 14. One of the channel-shaped members 38 or 40 may be rigidly secured to one of the legs 24 with a plate portion 36 being disposed between adjacent legs 24 wherein movement of the upper ends or bight portions of the frame members 12 and 14 toward each other is permitted but movement of the upper ends of the frame members 12 and 14 is limited due to engagement of the legs 24 in the oppositely inclined channelshaped recesses 38 and 40.
As illustrated in Figures 3 and 4, each of the legs 24 and 26 of each of the frame members 12 and 14 is sectional with a hinge construction generally designated by the numeral 42 interconnecting the adjacent ends of the sections of the legs. The adjacent ends of the sections of the legs are designated by the numeral 44 and -46 with each having a hinge pin 48 extending therethrough and extending through one end of an interconnecting link 50. One edge of the adjacent ends 44 and 46 is provided with an inwardly extending notch or slot 52 for permitting movement of the link 50 to a position perpendicular with the longitudinal axis of the legs 24. Carried on the bottom adjacent end 44, a transverse pin 54 is provided in spaced relation to the pivot pin 48 for limiting the vertical sliding movement of a sleeve 56 which bridges the adjacent ends 44 and 46 of the sections of the leg 24 for retaining the sections of the leg 24 in longitudinally aligned position. By grasping the sleeves 56 and moving upwardly to a position beyond the inner end or upper end of the upper notch 52, the sectional legs 24 may be folded to a position alongside each other substantially as illustrated in Figure 4.
Referring now specifically to Figure 5, it will be seen that the tray assembly 18 generally includes a rectangular body 58 of corrosion resistant material such as plastic, metal or the like which is provided with an enlarged concave recess 6t) on the upper surface thereof for receiving articles normally supported on a high chair tray. The opposite outer edges of the body 58 are provided with depending lugs 62 at the corners thereof receiving screw-threaded setscrews 64 having knurled heads 66 for clamping engagement with the support frame 16 whereby the tray 18 may be adjusted on the legs 68 of the support frame 16. The outer ends of the legs 68 of the support frame 16 are interconnected by a bight portion 78 wherein the support frame 16 is generally U-shaped with the free ends of the legs 68 being provided with hinge loops 72 pivotally interconnecting the bight portion of the frame member 12 with the support frame 16.
For supporting the legs 63 of the support frame on the upper end of the frame member 14, a pair of projecting lugs 74 are hingedly mounted on a pin '76 and project outwardly through slots 78 in the upper ends of the legs 24 and the adjacent outer ends of the bight portion of the frame member 14 thereby forming a support for the outer end of the support frame 16 and also the tray Supported between the legs 24" and 26 of the frame member 14 is a depending! U Sha'ped? foot rest 80' for providing support for a childs feet;
The seat and back assembly 26' includes. a seat 82, a,
lower been member as hingedly connected thereto by hinge means 86 and an upper back member 33 hingedly connected to the upper end of' the lower back member by hinge means hi). The upper back member 88 is pivotally connected to the bi ght portion 22: of the frame member 12 by hinge straps 92 for pivotal movement about an aXis formed by the bi'gh't portion 22; The front end of the seat 82 is supported by, a strap member 94 hingedly connected to the front edge of thes'eat 82 by hinge means 96 and including an elongated loop 98 which is pivotally and slidably positioned in encircling relation to the bight portion 22 ofthe frame member M'whereby the seat and back assembly 2t"? may be folded and also will permit limited rocking movement substantially as illustrated in Figure 6.
With the device in unfolded. position as illustrated in Figure 1, the chair 0 may be movedon the wheels 30 in a very easy manner and by adjusting the hand wheels or knurled heads 66, the tray 18 may be longitudinally adjusted on the frame 16' for permitting easy placement and removal of a child onto the seat 82. Also, the
support lugs 74 forthe support frame 16 permits the sup port frame 16 to be pivoted upwardly for facilitating placement of and removal of a child. The stop plates 36 permit the frame members 12 and 14 to be pivoted to a position alongside each other after which the support frame 16 may be pivoted downwardly substantially as illustrated in. Figure 7 inasmuch as the support hinge loops 72' are offset so that the legs 68 will move down wardly alongside of the legs of the frame member 14 when the lugs 74 are pivoted inwardly to a retracted position; The seat assembly 20 is disposed in folded relation between the bight portions 22 of the frame members 12 and 14 and the lower sections of the legs are pivoted upwardly alongside the upper sections thereby forming a very compact unit as illustrated in Figure 8 for ease of transportation or for ease of storage in a very compact condition whereby very little space will be used by the device and wherein the device may be easily setup or unfolded for use.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope ofthe invention as claimed.
