WACLAW DZIMITOWICZ, OF PITTSBURGH, PENNSYLVANIA.
Specification of Letters Patent.
Patented J an. 6, 1920.
Application led January 30. 1919. Serial No. 274,060.
To all whom 'it may concern.'
Be it known that l, McLAw DziMiTowICz,
a citizen of Poland. residing at Pittsburgh. in the county ot' Allegheny and State of lennsvlvauia. havel invented certain new and useful lmprovements in Baliy-lValkers, ot' which the following is a specification. i The primary object of the invention is the provision of a baby walker adapted to be coxnpactly folded when not in use and read- .il v set up for resiliently supporting a c hlld in walking position` the device bemg adjustable for children of dili'erent heights.
A further object of the invention is to provide anspring seat for small children adjustable in height with respect to the tloor upon which the device is adapted to itrave'l, provision being made for readily toldlng the structure and retaining the same 1n its knock-down form when not desired for use.
A still further object of the. invention is to provide a habiv walker that possesses great strength and one. that is compactly foldable for storage or shipping purposes and that is also easy and inexpensive to manufacture.
-With these and other objects in view the invention will be hereinafter more fully described in connection with the accompanying drawings and in which like reference characters designate corresponding parts throughout the several views.
In the drawings,
Figure 1 is an elevational view of the invention vset up for use,
Fig. is a top plan view thereof,
Fig. 3 is a detail sectional view of one of the adjustable leg members employed,
Fig. l yis a top plan view showing the hinge connection between the lower end of oneof the. leg membersl and a. corner of the supporting frame with said leg member latched in its folded position,
Fig. 5 is a sectional view taken upon line V-V of Fig. l,
Fig. 6 is a vertical sectional View showing the removable connection between the free end of one of the leg members and the table or railing of the device and Fig. 7 is a bottom plan View of a portion of said railing showing the socket member of the leg connection.
The general form of my baby walker is one that is well known in the art, broadly consisting of a rectangular frame 10 having a table or railing 11 1n the form of a ring supported upon said frame b v means of legs 12 while a seat board 13 for the child is resiliently suspended from the rail 11 by a plurality of helical springs 14. Suitable casters 15 are provided beneath the frame 10 for n'loving the device along the fioor such as 16 and the board 13 is provided with substantially semi-circular cut-away portions 17 adapted to receive the legs of the child therethrough when the child is seated upon said board with its body positioned upv .rdly through the, ring 1.1, the latter being convenient for grasping as well as retaining .the child upon said seat. 'l
The legs l2 are made adjustable in length so as to position the seat board 13 at different distances from the frame l() as well as above the. floor 1G to acconnnodate children of'different heights. T hese legs 1'2 are formed of two sections. the lower section 1S of each leg having a bolt 19 extending therethrough and through a longitudinal slot '.20 of thev upper leg `section 21, whereby tlghteniug of the wing-nut Q2 of the bolt .19, the leg sections 18 and 21 are retained adjusted for providing a leg of the proper length desired.
A hinge 23 is diagonally secured adjacent each corner of the frame 10 having one leaf '24 of the hinge attached to the outer side of the adjacent lower leg section 18, whereby the leg may be elevated at an inclination with theI frame 10 when the device i.'` set up for use as shown in Fig. 1 or may assume a horizontal position within the frame 10 when the device is folded as shown in Fig. 5. A spring latch is provided for each corner of the frame, upon which the bottom of the adjacent leg section 18 is adapted to rest when the device is set up, while the lat-ches 25 overlie the leaves 24 of the springs 23 when the legs are in their folded positions. v f
Headed studs 26 are carried by the free ends of the leg sections 2l adapted for reception within the sockets 2T upon the loWer face of the ring- 11. The socket member 27 has a U-sha-ped portion 28 opening inwardlyv of the ring and with an inwardly struck resilient tongue or spring 29 for engaging the end of the stud *2G when forced to its seating position within the socket.
The complete operation of the device Will be apparent from this detailed description thereof, the same being maintained set up for use by the legs 12 maintained open by thespring latches 25 and connected with the -ring 11 by the studs 2G and sockets 25.
When it is desired to place the invention in its folded form, the studs 26 are forced inwardly out of the sockets 27, the nuts 22 loosened and the'upper leg section 21 lowered to the desired extent and vupon swinging the latches adjacent one side of the frame, the legs may be freely folded inwardly of the frame 10.y rThe latches 25 will then "be returned to their former positions 'but overlying the leg portions 18 so that the same will be"prevented4f from opening .until the latches are again released.
A serviceable baby walker is provided'capable of accommodating different sized children and being foldable for storing away when not desired for use.
What I claim as new is 1. A device of the class described comprising a rectangular frame, supporting legs, hinges connected between said legs and pended from said ring, sockets upon the bottom. of the ring having U-shaped openings inwardly thereof, and provided with retaining spring portions, legs formed of upper and lower sections, studs upon the upper sections of said legs adapted for detachable connection with said sockets and securing means between the sections of said legs whereby the ring and seat are maintained at adjusted elevations.
3. A device of the class described coinprising a ring, a seat board resiliently suspended from said ring, sockets upon the bottom of the ring having U-shaped openings inwardly thereof, and provided with retaining spring portions, legs formed of upper and lower seetions,'studs upon the upper sections of said legs adapted for detachable.. connection with said sockets, and securing means between the sections of said legs whereby the ring and seat are maintained at adjusted elevations, a supporting frame, hinges connected vbetween said frame and the lower'sections of the legs, casters beneath said frame, and a latch for each hinge carried by the frame adapted for overlying said hinges when the legs are folded within the frame, the said latches being supportingly positioned beneath the lower sections of the legs when the device is set up for use.
In testimony whereof l affix my signature.
