ATTORNEY United States Patent Ofi ice No. 43,493, July is, 1962, Set. No. 200,685 (Cl. 297-477 This application is a continuation of my prior application Serial Number 43,493, filed July 18, 1960, entitled Support Stands, now abandoned. The invention relates to support stands and deals particularly with stands designed to support baby carriers of the type having an elongated back, opposed sides extending forwardly from the back, and a bottom connected to the sides and b ack. This type of carrier is preferably a one piece structure of molded plastic and is designed to support a baby when desired during the period from the age of birth to over a year old. Heretofore, it was necessary to prop the carrier up against some object such as a conventional chair or up against the wall. Oftentimes a baby's natural tendencies to squirm and kick would necessitate the use of tie straps or cords to hold the carrier in the proper position. This operation of necessity reduced the convenience of the carrier.

It is the primary object of this invention to increase .the utility of the baby carrier by providing a supporting stand which is adjustably connected to the carrier in such a way as to support the child in any of a series of positions and to provide a stand which will support the baby comfortably and safely in the carrier.

A feature of this invention resides in the provision of a supporting stand which will support a baby carrier in any of a variety of positions, allowing the baby to lie fiat or to be setup at any desired angle.

Another feature of this invention is the provision of a supporting stand for a baby carrier which is formed of a heavy gauge steel for rigid support of the carrier. The use of the stand in conjunction .with the baby carrier enables the carrier to be used in a wide variety of situations. For instance the carrier may be used as an attachment to a car seat, as a high chair when placed on a table, or in a stroller. The use of the stand with the carrier enables a mother to prop the baby up in the carrier safe and comfortable nearby while she goes about her housework.

These and many more objects and novel features will become apparent from the following description taken in connection with the drawing wherein;

FIGURE 1 is a perspective view of the back of a baby carrier showing the supporting stand attached thereto.

3,101,972 Patented Aug. 27, 1963 FIGURE 9 is an enlarged transverse sectional view of a portion of the carrier back panel and one side, said sect-ion being taken substantially on line 9.9 of FIG- U-RE 7.

The supporting stand is generally indicated by the letter A and in FIGURES 1 and 3 is shown attached to a baby carrier B. The back construction of the carrier is preferably formed to especially accommodate the use of the new invention. 7

The carrier shown includes an elongated back panel 10 having integrally formed

side panels

12 and 14. The side panels extend forwardly as at 16 and 18 and are integrally connected to a bottom 24 Said bottom, as seen in FIGURE 3, has a downwardly depending skirt portion, at the front end thereof, to limit forward tipping. The baby carrier of the type illustrated is normally a one piece molded structure formed of a comparatively rigid plastic substance.

As best seen in FIGURES 1 and 4 the rib portions 21 are provided with a series of sockets or apertures, the apertures in the rib on one rib portion 21 being aligned laterally with the apertures in the opposite rib portion 21.

The rib 22 is generally channel shaped in cross section, and the apertures 24 extend laterally through the outer wall of each rib portion 21 which is nearest the adjacent side edge of the back panel. Each rib portion 21 is provided with .a series of lugs or stops 26 projecting forwardly from the base of the channel-shaped rib in aligned relation with the aperture 24.

The carrier support A includes a base or lower frame generally indicated by the numeral 28. The frame 28 is a generally U-shaped rod formed of a relatively heavy gauge steel material. The

arms

30 and 32 of the frame are similar in length and converge towards each other some what from a connecting cross arm 34. The terminal ends 31 and 33 of the

arms

30 and 32 respectively are bent inwardly in opposed aligned relation and are pivotally inserted into aligned journals or apertures 36 at the lower ends of the rib portions 21 which terminate the juncture of the back and bottom of the carrier. The aligned apertures 37 are provided in the rib portion 21 so that the frame 28 may be journalled therein. In certain situations, such as when the baby carrier is placed upon an automobile cushion, this feature adds to the overall stability of the baby carrier.

The base frame 28 is sufficiently resilient-to permit the spreading apart of the arms and to permit engagement with the apertures 37.

The carrier support A includes a second or upper frame generally indicated by the numeral 38. This frame includes a pair of

resilient arms

40 and 42 of similar length which are connected at one end by a cross arm 44, the other or terminal ends 41 and 43 of the arms 40' and 42 respectively are bent at substantially right angles into aligned relation and are adapted to the pivotally inserted into the apertures 24 as is best seen in FIGURES l, 4 and 5. The free terminal ends 31 and 33 of the frame 28 and the terminal ends 41 and 43 of the frame 38 are normally closer together than they are when inserted into the apertures. This inherent resiliency causes the arms to pull towards each other and against the logs or stops 26. from the above description it will be seen that

arms

30, 32 and 40, 42 :form preloaded springs in that on each pair being forced apart-to enter aligned apertures or sockets, they exert a pressure on stops 26.

The frame 28 and the frame 38 are pivotal'ly connected and angularly related to each other as best seen in FIGURES 1 and 6. This connection is made by a pair of

bearingblocks

46 and 48 or the like which are formed of comparatively hard rubber substance or the like. The

blocks

46 and 48 encircle the side by

side cross arms

34 and 44 adjacent the bend in the framescona necting the connecting members and the arms and said blocks lie between said pairs of

arms

30, 32 and 4t), 42. The blocks will remain in this position because the intermediate portions of the cross arms are both bent offset as seen in FIGURE 1. The

blocks

46 and 48 are somewhat oval in cross section and are provided with an internal lateral opening 50. Access to the opening is gained by providing a slit 52 across the top of each block. The lower surfaces of the blocks are somewhat flat and may be provided with ribs 54 to provide a better grip upon the floor or other surface which the baby carrier is resting. Since the frame members converge inwardly from the connecting members, as noted above and shown in FIG- URE l, the frames have a generally trapezoidal form with a broad base, the two bases lying adjacent each other.

As best illustrated in FIGURE 3 the angular position of the carrier may be changed by inserting the

arms

40 and 42 of the frame 38 into the various apertures along the seat back. The older the baby becomes the more able he is to sit in a more erect position. Ideally position 1 is most healthful and comfortable for a baby from 8 months to a year. Position 2 for babies 6 to 8 months, position 3 for 3 to 6 months, position 4, birth to 3 months, and position for sleeping and carrying the infant.

When the frame 38 is disposed in the uppermost apertures both the

frames

58 and 28 will be folded flat against the outer surface of the back 10. Thus, necessarily, the vertical length of frame 38 plus frame 28 is the same as the vertical length between the uppermost and lowermost sockets and somewhat less than the total vertical length of the back 10.

The carriers are normally provided with a cord 56 which may be tied to a car seat for example, for added safety.

A modification of the carrier supporting stand is illustrated in FIGURES 7, 8, and 9. The carrier, generally indicated by the letter C is provided with a back 58 which is specifically shaped to accommodate a modified form of a support stand generally indicated by the letter D. The carrier C is preferably formed of a material which is somewhat pliable as compared to the material utilized in the formation of seat B illustrated in FIGURES 1 through 6.

The carrier C includes an elongated perforated or slotted back panel 58 having integrally connected forwardly extending sides 60. The side panels 60 flare outwardly at their lower ends forming slotted panels 64. A bottom, not specifically illustrated is attached to the side and back panels at the lower ends thereof.

As best seen in FIGURES 7 and 9 a pair of

opposed ribs

68 and 70 are formed at the connecting juncture between the sides 60 and the back panel 58. These

ribs

68 and 70 are for-med integrally with the sides and back panel. Eeach rib, which is generally semi-circular or channel shaped in cross section, is provided with a series of notches or cut-outs 72 which are arranged in transversely aligned relation with the notches in the opposite rib. As is most clearly seen in FIGURE 8 the major portion of each notch is circular as at 74, the entrance 7 6 to each notch being considerable smaller in width than the circular portion of each notch. The particular purpose of the above described arrangement will be described later.

The carrier supporting stand D includes a support frame which is generally rectangular in shape and is formed of a relatively heavy gauge steel rod material. As shown in FIGURE 8, the diameter of the rod is substantially equal to that of the circular portion 74 of notches 72 and is larger than the minimum width of entrance 76.

Side arms

78 and 80 extend substantially parallel from connecting

cross arms

82 and 84. The cross arm 82 is designed to be inserted into the circular portions 74 of aligned notches 72 by pushing the arm through entrances 76. Once snapped in place the arm resists accidental displacement from circular portions 74 of notches 72. The arm will transversely bridge the back of the back panel 58, the arms 78 and extending angularly therefrom. The cross arm 84 is provided with an offset intermediate portion designed to prevent a pair of oppositely disposed bearing blocks 86 and 88 from moving towards each other. These blocks are similar to the

blocks

46 and 48 described earlier in this specification.

The support stand further includes a base frame 90 which is substantially identical with the base frame 28 as shown in FIGURE 1. The

arms

92 and 94 of the frame are similar in length and extend in substantially parallel relation from a cross arm 96. The terminal ends 98 and 188 of the

arms

92 and 94 respectively, are bent inwardly in opposed aligned relation and are inserted into aligned apertures or sockets 102 at the lower ends of the

ribs

68 and 78. FIGURE 7 shows the sockets 102 to lie lower than the lowermost of said perforations. The frame 98 is pivotally connected to the frame 77 by the

blocks

86 and 88, the cross arm 96 being inserted in the blocks in side by side relation with the cross arm 84 of the frame 77.

The angular position of the carrier may be changed similar to the manner in which the positions are changed in the embodiment shown in FIGURES 1 through 6. To adjust the carrier the cross arm 82 may be withdrawn from the notches 72 by forcing the arm out through the notch entrances 76 and reinserting the arm into the desired transversely aligned notches. When the cross arm 82 is disposed in the uppermost notches both the

frames

77 and 90 will be folded fiat against the outer surface of the back 58.

In accordance with the patent statutes, I have described the principles of construction and operation of my improvement in support stands, and while I have endeavored to set forth the best embodiment thereof, I desire to have it understood that changes may be made within the scope of the following claims without departing from the spirit of my invention.
