15 Claims.

This invention relates to chairs and folding chairs and particularly to new and useful improvements on so-called baby high chairs. The term baby high chair as used herewith, refers specifically to that type of chair which not only has the conventional seat, back and sides common to all baby chairs, but in addition has a foot rest, an eating tray, and exceptionally long legs as a most distinguishing feature. These legs serve to raise a child to a comfortable 30-inch table level approximately for feeding.

A baby high chair by its very nature of height has a greater tendency to tip over than a low type chair. Therefore the general practice in the manufacturing field has been to make heavy, sturdy chairs to overcome possible accident to the child. The sturdiness of these chairs results not only from their natural weight, but also from the fact that all the component members of the chairs are rigidly interconnected with one another, except possibly one or two members such as the foot rest and the eating tray which must be adjustable for proper functioning. As such, these chairs are not collapsible and portable.

The object of this invention is to provide a baby high chair which can be practically manufactured and which is not only sturdy and safe, but in addition can be completely collapsed or folded into a light, compact, portable unit having far reaching advantages over existing chairs in the consumers market.

This invention is not to be confused with the group of baby chairs now on the market which, although completely collapsible and portable, do not comply with the definition of a baby high chair given above. Some of these chairs are merely sitting chairs that are not suitable for feeding purposes. As these chairs have short legs and few component members, the problem of proper construction to produce a completely collapsible, portable unit is a relatively simple one. Other chairs with more component members and suitable for feeding purposes still fail the definition of a baby high chair in one major 'espect. These chairs have short legs, and height can be achieved only by strapping the chairs to a regular chair. My improved chair on the other hand has height inherent in the construc tion of its legs and does not clepend'on some auxiliary mounting as described above, and in addition can be used in a low position as well as a high position. It is to be remarked also that the collapsible, portable chairs heretofore known are sectional in construction, and require that the seat, back, sides, etc. be dismembered from one another before being stacked into a suitable car rying medium for transportation. The chair herein presented is not of sectional construction. All members remain interconnected during the process of collapsing and folding the chair, and

to achieve this result presents more of a constructional problem than in the sectional type of chair.

The usefulness of the invention in the consumers market will be readily appreciated in view of the following observations.

(1). Many people with children up to 3 years of age going on vacations or visiting beaches, inlaws, and friends will find a babys high chair of a completely collapsible and portable nature to their advantage and convenience. Carried in the trunk compartment of a car, under the arm, or in a suitable carrying medium, it can be readily put to use at the arrived at destination so that the necessity of feeding a child in ones arms or seating the child uncomfortably on a, regular chair can be eliminated.

(2) In cramped apartments or living quarters the ability to be able to put one of these portable collapsible chairs away in some corner of a closet is a decided advantage over the present heavy, clumsy chairs now supplied for the home, which, because they arenot collapsible must stay in the middle of the floor, even when not in use.

(3). Restaurants, having very little convenience at present for accommodating customers with children because they will not tolerate the present type of high chair on their premises for obvious reasons, will find my storable unit of great advantage.

While this invention relates more particularly to high chairs for babies, it is noted that in many of the claims the invention is not limited to high chairs.

Additional objects of the invention are to effect simplicity and efliciency in such chairs and to provide an extremely simple chair of this kind which is convenient, durable, and reliable in use, and economical to manufacture, pack and-ship.

Still other objects of the invention will appear as the description proceeds; and while herein details of the invention are described in the specification and some of the claims, the invention as described'in the broader claims is not limited to these, and many and various changes may be made without departing from the scope of the invention as claimed in the broader claims.

The inventive features for the accomplishment of these and other objects are shown herein in connection with an adjustable folding or collapsible high chair for babies which briefly stated, includes telescoping legs hinged to and foldable adjacent to the chair seat, and a back and up-- right side arms hinged to the seat and superposable upon the seat. A tray disposed on the upright arms and linked to the seat and detach ably linked to the upright arms is foldable to be disposed over the superposed arms and back. A foot rest panel detachably secured beneath the seat and intermediately linked to the front of foot rest, is adapted o ded. thereon to be folded he folded legs. Means are iolde osition for s. or easy carrying. il'ie pa ts may easily and quickly changed from foule to erected position. A latch is provided to hold the sections of the telescoping legs at the limits of the telescoping movement.

My improved folding high chair comprises a rectangular seat is of thick material to which is secured a thick front spacing and supporting bar H disposed along the front margin of the lower face of the seat and terminating some distance from the side edges of the seat. A pair of front plate-hinges i2 is disposed at the ends of the bar, each having apertured flat portions [3, i secured fiat against the bottom and rear faces of the bar, and a curved intermediate bearing portion E5 forming with the bar a bearing opening axially parallel to the bar. Another pair of rear plate-hinges i8 is disposed at the rear margin of the lower face of the seat nearer to the side edges of the seat than are said front hinges i2 and comprising front and rear flat portions IS (Fig. 3) secured fast to the seat and a curved intermediate portion 2a forming with the seat a bearing open ng axially parallel with the rear edge of the seat.

The legs of the chair are not constructed as independent units. Front and rear tubular metal log units 7.2, hingedly carried by said hinges are bent to form inverted U -shaped tubular members comprising yokes 24, 25 hingedly received in said bearing openings and straight divergent leg upper sections 25 (Fig. 1) all of equal length, the yoke 25 of the rear unit being longer than the yoke 2d of the front unit.

Sturdy stop rods 28 disposed along said yokes respectively between the hinges comprise inturned ends 29 welded to the yoke and an intermediate part parallel to and spaced from the yoke and engageable with the seat and said bar H respectively to limit the outwardly swinging movement of the unit to a position as shown in Fig. 1 in which the leg sections of the front section diverge from the re r sections at an angle approximately the angle of divergence of the leg sections of the same unit.

Straight lower leg sections 32 of slightly larger diameter than the upper sections 25 are telescopically slidably received on the upper sections and each provided with a rubber foot 33 pressed over its lower free end. Said leg units when the sections are telescoped are disposable with the rear unit 23 against the seat and the front unit 22 disposed against the rear unit in a plane closely spaced and parallel with the seat.

A latch assembly 34 (Figs. 2, 5 and 6) secured to the upper end of each lower section for holding such lower sections in telescoped or extended position comprises a band 35 intermediately spot welded to the tube and provided with spaced parallel outturned end ears as having axially alined apertures therein receiving an internally threaded headed bushing 31 and a headed mating screw 35 in the bushing, the bushing and screw constituting a fulcrum pin carrying a latch lever 39 intermediately fulcrunied on said pin and comprising an inturned tip 40 disposed beyond the end of the lower section. A spring strip 42 secured to the other end of the lever presses on the lower section to urge the tip 40 in warclly. lfhe outer face of each upper section is provided with an inwardly pressed longitudinal groove and in the end parts of the groove with holes M, 45 (Figs. 1 and 6), the groove 43 receiving and guiding the tip to the holes for the reception of the tip 4% by a hole to hold the lower section at its inner or outer limit of movement, and preventing the lower section from twisting on the upper section.

ihis sliding arrangement of the lower sections on the upper sections over the inner tube 26 makes possible the use of this chair not only in its high position but also in a low position when so desired. Also since the proposed chair is completely collapsible, the fact that the leg unit can be shortened prior to rotating it flat against the bottom of the seat adds an unusual compactness to the folded products.

In rotating the leg assemblies in opposite directions against the seat, they must be of necessity by-pass one another, and because of the characteristic flared U-shapes of these assemblies, this can be accomplished by making the yoke part 25 longer than the yoke part 2-1. Also in order that the two leg assemblies fold perfect- 1y flat and parallel to one another and to the seat, it is necessary to offset the axes of rotation by mounting the yoke part 24 on the bar I I. This offset explains why the rear leg assembly is shown longer as well as wider than the front assembly in the various illustrations.

Stiff metal bands spot welded to the lower part of each lower section have each an end bent to form a projecting ear #9 (Fig. 9), the ears of the front and rear leg sections when the sections erected pointing toward the adjacent rear and front sections respectively. A pin or bolt having a plain intermediate part is carried in each ear. A brace bar 5: of vertically elongated cross section associated with each band has one end pivotally received on said plain part of the bolt and held by a nut 38'; and a friction washer 52 (Figs. 2 and 9) is disposed between each bar and ear.

The other end 53 of each bar is provided near such end with a short longitudinal slot 54 havin one end 55 terminating near such end, the other end of the slot being provided with an open end 53 opening downward when the bar is horizontal. Each bar is provided near said slot with a transversely disposed headed pin 51, each pin being adapted to be received by the closed end of the slot of the other bar to hold the bars in alinement and against longitudinal movement toward each other, to hold the extended diverging front and rear legs against movement toward each other. The bars also help the sturdy stop rods 28 to hold the legs from moving outward from each other. Said pins 51' are adapted to be moved to the open ends of the slots to allow the bars to move relatively angularly upwardly to allow each pin to leave its associated open end, to allow the bars to be disposed along their associate leg sections as in Fig. 3. Each bar Si is also provided near its hinged end with a short longitudinal slot similar to the slot 54 and closed at the end nearest the hinged end and downwardly open, when the bar is horizontal, at the other end, and adapted to receive the pin 51 of the other bar to hold the leg units in proper diverged position when the chair is used as a low chair as in Fig. 2. The friction washers 52 hold the bars from dangling when the chair parts are being folded.

Spacing bars 55' of rectangular cross section are secured to the side margins of the chair seat It; and a fiat back 56 hinged, at the front edge of its lower end edge face, by a hinge 51 to the rear margin of the upper face of the seat between the spacing bars is adapted to fold flat against the seat between the spacing bars. Thin flat side arms 50 hinged by hinges 6| (Fig. 2) to the upper inner edge of the respective spacing bars 55 are adapted when erected to be disposed near the side edges of the raised back and are adapted when the back is folded on the seat to be disposed toward each other on the back, as shown in Fig. 3.

An angle piece 63, 64 (Fig. of fiat metal strip has one member 63 mounted fiat on the inner side face of the upper rear corner of each side arm 90 and has its other member 54 projecting slightly behind the back when raised. A block 65 mounted in the angle of said piece against said members is provided with a bore 66 carrying a cup 6'! having a flanged open end adjacent to the back, and a yieldably projected rounded button 58 mounted in said cup is pressed by a spring 69 in the cup to project adjacent to the edge face of the back when raised. A flange ill on the button engages the flange H of the cups to limit outward movement of the button. A socket plate i2 mounted on said edge face of the back is formed with a socket 13 into which said button is pressed to yieldably hold the back raised. Said member 64, the button and the hinged lower edge face of the back cooperate to hold the back against excessive backward movement.

Outwardly laterally projecting pivot studs (Fig. 1) on the forward part of the outer face of the spacing bars 55' pivotally receive lower ends of strut links 15. An eating tray 11 disposed over said arms has its lower forward margin disposed forward of the arms and hinged by hinges 19 to the upper ends of said links 16. A bracket 80 on the lower face of each rear corner of the tray carries a hook link 8| pivoted at its upper end on the bracket and disposed at the outer face of the arm and provided at its lower end with a forwardly open hook slot 82 adapted to receive a lock pin 83 provided on the adjacent portion of the arm. A manipulating knob 84 is provided fast on the outer face of the intermediate part of the lock link.

A flexible safety strap 85 to prevent the child from slipping through the opening under the tray has its lower end secured by a screw St to the front edge face of the seat and has its upper end detachably secured by a snap button 81 to the lower rear margin of the tray. Rubber buttons 89 on the lower face of the rear corner parts of the tray engage the upper edges of the erected arms, and rubber buttons 9i] on the upper face of the front part of the arms engage the under face of the tray. Said buttons being under compression serve to keep the sides firmly spaced apart and to increase the rigidity of the mounting of the tray.

Said front spacing supporting bar 1 I has longitudinal bores in the forward parts of its ends receiving bushings 82 (Fig. 2) receiving inwardly turned ends of a U-member 94 of rod material having a straight yoke 95, and upwardly extended intermediately forwardly bent arms 96 carrying said ends 93.

I provide a foot rest assembly 98 comprising a main panel 99, and side bar members It? secured on the upper face of the side margins of the panel and extending from the lower edge of the panel to a position beyond the upper edge, the lower face of the side members being intermediately provided with transverse bearing notches IEH receiving said straight yoke 95, whereby the foot rest panel is linked to the spacing bar. A rod I62 connecting the upper ends of the side members is received in a deep downwardly open transverse groove I83 in a detent block I M secured just forward of the middle of the lower face of the seat to cooperate with said U- member to hold the foot rest in inclined position, said block being provided with a bore me transverse to the groove and communicating with the lower part of the groove in which bore is disposed a button catch assembly I95 similar to that of Fig. 10 including a yieldably pivoted button catch I01 disposed below the rod I02 to yieldably hold the rod in the groove. A foot rest 5 68 between the lower ends of said side bar members has its inner lower edge part hinged by a hinge I98 to said panel whereby the lower edge face of the foot rest engages the panel to hold the foot rest perpendicular to the pan-e1. Rubber buttons Hi! on the end edges of the foot rest yieldably engage the side members I89 to hold the foot rest when folded on the panel.

Said foot rest assembly when folded and when the legs are telescoped and folded adjacent to the lower face of the seat and said rod is withdrawn from the groove, is adapted to be moved to engage on the yoke of the folded front legs, there to be held by a spring clip Iii (Figs. 3 and 4) mounted on the lower face of the seat in position to engage said rod when the foot rest assembly is thus disposed.

Said tray ii when the hook link i and safety strap are disengaged and the back and arms are superposed on the seat, is adapted to be disposed flat on the arms. A sheet metal member II3 (Figs. 1 and i) at each end of the tray is bent to form feet H4 secured to the lower face of the tray, when the tray is horizontal, and a pending stem having a lower angular head H5, received by and within a U-shaped spring keeper clip I I6 having the lower part secured in a housing II! secured to the rear part of the side face of the seat. Said keeper has upturned spring arms I I8 between which said head I i 5 may yieldably engage when the tray is thus folded, to hold the tray on the folded arms.

The inner lower part of each front lower leg 7 section is provided with a transversely projecting pin I20 (Figs. 3 and e) on which the hook link 8i may catch to cooperate with the strut links 16, heads H5, catches Ill and keeper clips H6 to hold the tray ll, arms 60, back 56 and seat l8 superposed and to hold the legs against the seat, whereby the high chair is held compactly folded for convenient carrying or storing.

The tubular leg units and sections may be made of steel, stainless steel or other suitable metals, alloys or materials. The seat, back, sides, foot rest assembly and spacing bars If and 55 may be made of wood, plywood, plastic, aluminum or other suitable material. Other parts may be of metal and other suitable material. The entire chair may be made of aluminum, Duralumin, or other suitable light metal.

The operation of folding the chair from the position of Fig. 1 to compacted position is very simple.

The upper end of the safety strap 85 and the lower end of the hook link 8i are disengaged. Then the entire tray and struts 18 are rotated in the direction of the arrow I22 (Fig. l) a sufficient istance to allow the back 55 to be folded flat against the seat, after which the sides 50 are closed flat against the back.

Next the tray is moved in a direction opposite to the arrow 22 until it lies flat on the sides 60, making sure at the same time that the heads H are received in the keeper clips 115.

After the tray is thus secured. the partially folded chair may be inverted and rested on a tab-1e 01' the floor. The bars 5! are then longitudinally moved slightly toward each other to bring the pins 5! over the open end 58, after which the bars 5! are swung toward the seat, disengaging them from each other and each brought to a position along its associated leg. The legs are then telescoped to their shortest length. The rear leg assembly is then folded fiat against the bottom face of the seat, after which the front leg assembly is folded against the rear legs as in Figs. 3 and i, and the hook links 81 are engaged on the pins 20 as in Fig. 4.

As the legs of each assembly are far apart, the above folding of the legs may take place while the foot rest assembly is in unfolded condition of Fig. 1. After the legs are folded to the position of i, the foot rest assembly may be also moved to the position of 4. The foot rest I03 is moved against the panel the rod I02 is detached from the recess X83, and the panel swung to the position of Fig. 4, the rod 102 being caught held by the catch HI.

The com letely folded chair is now ready for transportation either under the arm or in a suitable or box. The operations in collapsing the entire chair are very simple, and the entire sequence can be accomplished in about fifteen seconds after practicing afew times.

The reverse operation of erecting the chair to the positions of Figs. 1 or 2 is effected merely by reversing the operations and sequences just described. If a low chair is desired, the legs are allowed to remain telescoped as in Figs. 2 and 4- and the pins 5'! are caught in the slots 54a (lower part of Fig. 1) instead of in the slots 54.
