ADJUSTABLE SLIDE DEVICE FOR ATTACHING THE TABLE OF A HIGH CHAIR TO THE ARMS THEREOF Filed April 8, 1946 Patented Aug. 9, 1949 UNITED STATES ATENT 'OFFICE ARMS THEREOF Nathan J. Kroll and Samuel Kroll, Chicago, 111.

Application April s, 1946, Serial No. 660,562.

3 Claims. (01. 155 -127) This invention relates to adjustable slide devices. More particularly the invention relates to an adjustable latch for latching the table of a high chair to the opposite parallel arms thereof. The invention has as one of its principal objects the provision of an improved construction of this character which will be highly efficient in use and economical in manufacture.

It is not unusual "for a baby or child in occur pying a high chair with .a table attached to the parallel arms thereof, to grasp the table and shake the same to create a noise. Our improved adjustable slide device, when associated with a high chair of the character hereinbefore described, utilizes a latching arrangement which performs the two-fold purpose of releasably latching the table in an adjusted position with respect tothe opposite parallel arms of the high chair and also serves to yieldably resist the shaking of the table by the child relative to the chair arms whereby to discourage the baby or child in its playful shaking ofthe table.

Yet another and equally important object is the provision of fan adjustableslide. device having a latch provided withlsp'aced teeth which engage the track of the device, thus latching the slide 7 to the track at two differentpoints.

Another and equally important object of the invention is an adjustable slide device of the character hereinafter described in which the latch structure is selfiadjustable in spaced notches provided. in a wall orfiange of the track of the device. This enables the attendant to place the table in anadjusted positionupon the opposite parallel armsof the high chair without the necessity of' first adjusting the latch mechanism. 7

Another and equally important object of the invention is the provision of an adjustable slide device in which the latch mechanism is operable by application of pressure of the fingers of the hand thereon, thus enablingfremoval of the table with facility from an adjusted position upon the parallel arms of the high chair by merely compressing the hand. 7

Another object of the invention is the provision of an adjustable slide device of the character hereinafter described Whichcomprises relatively few parts and in which. the parts are so constructed and designed as permits the assembly to be 'used on either the right or lefthand side of the chair, thereby eliminating the necessity of havin right-hand and left-hand assemblies.

Yet another and equally important object of the invention is the provision of means on the track for locating the top surface of the track in a proper position upon the arm of the high chair whereby the top surface of the track upon which the slide member moves, will be alwayselevated above the arm of the high chair, and which means will greatly facilitate locating the track upon the arm of the high chair without the use of complicated tools 'suchasa'jig or-fixture or the like.

Other objects will appear-hereinafter.

The invention consists in the novel combination and arrangement ofparts to be hereinafter described and claimed. v V

The invention will be best understood by reference to theraccompanying drawings showing the preferred formbf construction, and in which:

Fig. 1 is a fragmentary side elevational view of a conventional, high chair showing our improved adjustable slide device associated therewith;

Fig. 2 is "a top plan View of the same;

Fig. 3 is a fragmentary perspective view of the underside of the high chair table showing our improved slide device-associated therewith;

Fig. 4 is a fragmentaryperspective 'view of one of the arms hi the high chair illustrated in Fig. 1, showing the track embodied[incur invention as sociated therewith;

Fig. 5 is a fragmentary sectional detail view taken substantially-on line 5-5 of Fig. 1.

A conventional high-chair of a standard construction and one which is well-known in the art and in common use, includes aseat I0 supported by the usual legs l From this seat I!) extends a back 12 and on the opposite sides thereof and connected in a conventional manner to the seat ill and theback IZar'e arms l3 'of the highchair, each including the parallel top rails M. 7

It is with such ahigh chair that our approved adjustable slide device is associated.

In this connection, as shown in Fig. '4, our improved slide device comprises a track l5 formed substantially channel-shaped in cross section, providing a top It and spaced depending flanges l1 and I8. The .fian'ge I8 'isjse'cured to the arm Id of the highchair by means cf connecting screws H9 or the like. The flange "has its opposite end portions 20 tapered to provide 'cam edges 2| for reasons which will be hereinafter more fully explained. This flange I! is "provided with a plurality of spaced slots 22.

While we have shown three ofthese slots in Fig. 4, it is to be understood that any number of such slots may be employed.

The opposite end portions 25 of the "top wall l6 are beveled downwardly as at 26 so as to facilitate guiding the slide member 21 upon the track. This top wall It has extending therefrom lateral spaced tongues 28 which are disposed in a plane below the plane of the top surface of the wall It whereby when the track I is mounted upon the chair arm 14, the top surface of the wall l6 of the track I5 will be above the plane of the arm l4, thereby to support the table 29 of the high chair above the chair arms l4.

The slide member 21, like the track i5, is channel-shaped in cross section to provide a top flange 30 which is secured by means of connecting screws 3i to the underside of the table 29. The opposite flange 32 is provided, at its junction with the medial wall 34 of the slide member 21, with slots 35 which extend at right angles with respect to each other. There is struck from the medial wall 34 spaced mounting lugs 36. These mounting lugs- 33-.areprovided withtrunnions 31 whichextend inwardly toward each other and engage in openings 38 formed in a latch plate 39. This latch plate 39 provides, at opposite end portions, latch fingers 40 which extend substantially at right angles with the medial wall 4| of the latch plate 39, and these latch fingers 40 operate in the slots 35. The latch fingers 40 each provide stop lugs 42 which limit the pivotal movement of the latch plate 39 by action of the spring 43, oneend of which is connected as at 44 to the slide member 21 and the opposite end as at 45 to'the latch plate 39.

The opposite end portions of the medial wall 34 are flared outwardly as at 46 to facilitate guiding the slidemember upon the track [5.

The slots 22 of the track l5 are of a depth such that when the latch fingers 43 engage in these slots, the latch fingers -will bear against the flange 11, thereby yieldably urging the top wall It of the track again-st the flange 30 of the slide member 21 to compensate for any relative movement between the tab1e'29 and the arms of the chair l4, which movement may be effected by the childs attempting to rattle the table 29.

In our mounting the adjustable slide device embodying our invention, upon-the high chair, the tongues 28 will locate the plane of the top wall-16 of the track l5 with respect to the top of the chair arm l4, and in assembling this track [5 upon the arm l4, itis necessary only to position the track in-its proper position with respect. to the longitudinal side edge of the arm [4. From this it will be seen that it requires but a simple operation to attach and locate the track upon the arm I4. a

After the track and slide member have been attached to their respective elements of the high chair, to-wit, the arm I4v and the table 29, in mounting the table 29 upon the arms, the slide member is telescoped over the track, this telescopic movement beingaided 'by the beveled end portions 25 and 46 of the track and slide member, respectively. As the slide member is moved longitudinally of the track toadjust'the table upon the arms M, the leading latchfinger 43 will engage the cam' edge 2!, which engagement will, whenthe table 29 is moved relative to the arms l4, automatically pivot the latch plate 39 from an unlatched .position where such plate will be held until the latch fingers engage in any pair of the'slots of the track,

' Assuming that there is a sufficient space between the inner edge of the table 29, as indicated at 29', and the back [2 of the chair, it will be obvious that when the chair is unoccupied, the

attendant may remove the table 29 by movement of the table in a forward or rearward direction relative to the arms of the high chair. With the latch fingers 40 engaged in a pair of the slots 22, by action of the spring 43 any relative movement between the slide member and the track in an upward direction will be transposed to the To remove the table 29, the attendant places both hands upon the opposite side edge par-- tions 30 of the table with the fingers of the hands in engagement with the latch plate 39. By flnmly grasping the edge portions 30' of the table 29 and by slightly-compressing the hand, the fingers will be caused to pivot the latch plate 39 against the action of the spring 43 to position to disengage the latch fingers. from the slots 22 into whichthey engage. The table then can be readily removed. From the description herein, it will be apparent that our improved adjustable slide device comprising few parts and that the parts are so arranged and designed as to permit assembly of the device on either the right of left-hand side of the table, thereby eliminating the necessity of right-hand and left-hand parts. 7

While we have illustrated and described the preferred form of construction for carrying our invention into effect, this is capable of variation and modification without departing from the spirit of the invention. We, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail ourselves of such variations and modifications as come within the scope of the appended claims.
