1 Claim. (Cl. 155-48) The present invention relates to infant chair attachments for tables, and more particularly, to chairs of the type which can be collapsed under the table when not in use.
The primary object of the invention is to provide an infant chair construction having adjustable clamping means for pivotally securing the chair to the table permitting the chair to be swung under the table to an out of use position.
Another object of the invention is to provide a construction as described above in which a folding leg supports the outer end of the chair.
A further object of the invention is to provide an infant chair of the class described above having a suspended cloth seat and an adjustable back.
A still further object of the invention is to provide an infant chair of the class described above which will be inexpensive to manufacture, simple to assemble and use, and completely safe from accidental collapse.
Other objects and advantages will become apparent in the following specification when considered in the light of the attached drawings, in which:
Figure 1 is a side elevation of the invention shown attached to a table, partially in section and partly broken away.
Figure 2 is a top plan view of the invention with the adjustable back removed, partially broken away.
Figure 3 is a vertical cross-section taken along the line 3-3 of Figure 1, looking in the direction of the arrows, with parts broken away for clarity.
Figure 4 is an enlarged fragmentary vertical cross-section taken along the line 4-4 of Figure 2, looking in the direction of the arrows.
Figure 5 is an enlarged fragmentary transverse crosssection taken along the line 5-5 of Figure 1, looking in the direction of the arrows.
Figure 6 is an enlarged fragmentary transverse crosssection taken along the line 6-6 of Figure 2, looking in the direction of the arrows.
Figure 7 is an enlarged fragmentary vertical cross-section taken along the line 7--7 of Figure 1, looking in the direction of the arrows.
Figure 8 is an enlarged fragmentary lateral cross-section taken along the line 8-8 of Figure 2, looking in the direction of the arrows, with the adjustable back in position.
Figure 9 is a fragmentary enlarged vertical cross-section taken along the line 9-9 of Figure 1, looking in the direction of the arrows.
Referring now to the drawings in detail wherein like reference numerals indicate like parts throughout the several figures, the reference numeral 20 indicates generally a table of conventional construction having a top 21, legs, one of which is illustrated at 22, and depending flanges 23 which support the top 21 and the legs 22. The flanges 23 are normally spaced inwardly from the lateral edge 24 of the table as illustrated in Figures 1 and 4.
The table 20 described above may be of either wood or metal and of any general or conventional construction.
ice j A clamp, generally indicated at 25, comprises a base plate 26 having an upstanding internal flange 27 formed on the inner edge thereof and extending at right angles thereto. A set screw 28 is threaded through the flange 27 for adjustment therein. A set screw 29 is threaded through the plate 26 and extends vertically at right angles to the plate 26 and to the set screw 28. A pair of upstanding webs 30 and 31 are integrally secured tothe plate 26 at the end thereof opposite the flange 27.
The upper ends of the webs 30 and 31 are bridged by a flat member 32 which is integrally formed with the ' webs 30 and 31 and provided with a portion 33 which extends inwardly from the webs 30 and 31 parallel to and overlying the plate 26. The set screw 29 is adapted to engage under the .top 21 of the table 20 clamping the top 21 between the portion 33 of the member 32, and the set screw 29. The flange 27 is adapted to engage behind the table flange 23 with the set screw 28 bearing thereagainst to lock the clamp 25 to the table 20.
A frame, generally indicated at 34, is formed in a general U-shape having opposed sides 35 and 36, and a back 37, the front being open. The frame 34 comprises a generally box-like member having a bottom 38, opposed sides 39 and 40, and a top 41. The inner side 40 and the top 41 are provided with a flange 42 adjacent the upper inner edge of the frame 34. The side members 39 and 40 of the frame 34 are provided with depending offset portions 43 and 44 which are positioned between the webs 30 and 31 and secured thereto by means of pivots 45 and 46 pivotally securing the frame 34 to the clamps 25.
A plurality of flat hooks 47 are secured to the inner side 40 of the frame 34 and are adapted to have a cloth seat 48 suspended therefrom by means of metal grommets 49 secured to the cloth seat 48. The cloth seat 48 is provided with a pair of leg openings 50 and 51 to permit the infant to put his legs therethrough.
A back member 52 is pivotally secured to the frame 34 by means of pivot 53 extending through the lower edge of the back 52 and into the frame 34 at its opposite ends. A bracket 54 is secured to the top wall 41 and the back 37 of the frame 34 and an adjustable link 55 is pivotally secured at 56 to the back 52 having teeth 57 for engaging the bracket 54. The use of the bracket 54 and link 55 permits the back 52 to be angularly adjusted to suit the needs of the infant using the chair.
A V-shaped leg, generally indicated by the reference numeral 58, comprises a V-shaped tubular lower member 59, a pair of oppositely disposed middle members 60 and 61, and a pair of oppositely disposed upper members 62 and 63. The middle members 60 and 61 are hinged at their lower ends with hinges 64. The upper ends of the middle members 60 and 61 are hinged to the lower ends of the upper members 62 and 63 by hinges 65. A slidable pin 66 is internally mounted in the members 61, 62 and 63 adjacent the hinges 64 and 65 thereof. The pin 66 is provided with an operating shaft 67 extending through slots 68 and 69 in the members 68, 61, 62 and 63.
In Figure 9, the locking relation of the pin 66 to the members 59 and 60 is illustrated. To collapse the leg 58, the pins 66 must be moved out of the joint permitting the hinges 64 and 65 to operate. The upper ends of the members 62 and 63 are respectively pivoted at 70 and 71 to the sides 35 and 36 of the frame 34. The leg 58 being adapted to pivot about the pivots 70' and 71 to a position lying within the frame 34 so that the frame 34 can be pivoted to the dotted line position illustrated in Figure 1.
A hook 72 is pivotally secured to the underside of the table top 21 by means of a bracket 73 and is adapted to engage in an opening 74 in the frame 34 as illustrated in Figure 7 to support the frame 34 in collapsed position beneath the table 20. It is obvious that in the use of in collapsed position beneath the'tableZO, as illustrated in dotted lines in Figure 1, so that the table 20 may be used in a normal manner.
The frame34 is'swung 'to'the' full' 'line position illustratedin'Fig'ure 1 when itisdesired to make used the chair and the leg 58 is' swung to the full line position illustrated in Figure 1 with 'the 'pins 66 moved into' locking'position. The back 52 is erected andsupported by means of the link 'SSand the chair is ready for use. Obviously, the cloth seat 48 'maybe removed for washing whenever desired.
Having thus described the preferred embodiment of the invention, it should be understood that numerous modifications and'struc-tural adaptations may be resorted to without departing from'the scope of the appended claim.
Wh'at'is claimed is:
In an infant-chair attachment for tables a leg comprising, a pair of spaced apart downwardly converging upper tubular members, a pair'of spaced apart downwardly converging middle tubular members having their upper ends respectively hingedly' secured to the lower ends of said upper members, a V-shapedlower tubular'member having upwardly diverging sides 'terminating'in spaced upper ends hingedly secured to the lower ends of said 4 middle members, a rigid pin slidably mounted in the lower end'of each of said upper members for telescopic en'- gagement into the upper ends of said middle members to releasably lock said upper and said middle members rigidly in axially aligned relation, and a rigid pin slidably mounted in the lower end of each of said middle members for telescopic engagement into the upper ends of the diverging sides oflsaid'v lower member to releasably lock said middle member and said lower member in rigid axially aligned relation.
