TEETERING DEVVICE Filed July 23,- 1945 2 Sheets-Sheet 2 f/Vl/E/VTOR Elmer /7- Lo/fer HTTOfF/VEY Patented May 31, 1949 UNITED OFFICE LokenSioux. City, Iowa, assignor of. onehalf to. Edward B. Sta-lily, Sioux City, Iowa Application July 2a; 1945, sesame sosgcov' a claims, (01. 21 2-54) My invention relates to a teetering device;

An object of my invention isto provide ateetering arrangement wherein the teeteringeffeet is obtained bythe manipulation-eithe hands- With certain membersin'. connection with. the usual manner of operation.

A further object of my invention is-to-provid'e' an arrangement wherebythe teetering effect' can be caused as desired, by one person-only;

A further object of my invention is to provide an arrangement wherein the teetering effect is provided by means ofthe feet in conjunction: with the hands, etc.

A further object of my invention istoprovi'de a well balanced arrangement which is easily operable by children, is simple to manufacture, and can be manufactured at areasonable cost.

With these and other objects in view, my invention consists in theconstruction, arrangement, and combination of the various" parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and'illustrated in the accompanying drawings, in which:

Figure 1 is a side sectional-elevation of tliedevice and taken substantially along the lines 1-4 of Figure 2,

Figure 2 is a plan view of Figure 1,

Figure 3 is a side sectional elevation of a modifled form of the arrangement,

Figure 4 is an end detail of the base of the arrangement shown in Figures 1 to 3 inclusive,

Figure 5 is a further modification, and

Figure 6 is a plan sectional view taken along the lines 66 of Figure 5.

I have used the character It] to designate a pair of spaced base members to which are attached the rubber bosses II for resting the arrangement upon the floor, and attached at I2 to the members 10 are the upwardly converging supports l3 which terminate at the apexes l4. Attached to the portions M are spacers 15. The teeter board itself is indicated by the character 16 and is preferably made up of a fiat piece with its width being positioned vertically as shown, the member 16 being attached at I1 to the two seats 18. Attached at 19 to the member 16 and at either side thereof, are the downwardly converging pieces 20 which are attached together at 21, a further piece 22 being attached therebetween as a filler member.

Passing through the portions l4, I5, 22, and the member 16 is a substantially strong pin 23, upon which pin the member 16 rocks.

Pivotally attached by means of suitable pins at124 are. the; lengthened links 25-whi'ch are pivote ally attached. at. 26' between the pairs of i vertical arms; 21, which arms 21 straddle the member 16, Theaarms; 21. are pivotedon the lower shafts 28 which pass through the base members 10 and include suitable spacers 29 attached thereto (see The members 21 are further braced Figure 4). at 3llsand are; attached at 31 to the handles 32,

and attached at 33 across the members 2 1- are:

thefoot receiving. bars 34.

It will now be seen that children seatedupontheseatsz. Hi, When grasping the handl es 32 and forcing them. baekwardly and forwardly in: the:

direction. of the arrows 35 will cause the arms 2 1 pivot at 2'8, atthe sametime causing the links. 25 to rock the members ill 'through'the pivot. connections. at 24. Since the members arrangement, since the use of the hands: on:

thehandl'es; 32' will maintain. the rockabl'e por tionsofthedevice at any inclined: position. This manual operation also is amusing, balances the working parts, and makes the teetering action much easier. The children can rest their feet on the cross-bar 34, and by pushing on the same inwardly will assist in the above described action.

Figure 3 illustrates a modified form of the arrangement wherein most of the above described parts are used, these parts being designated by the same characters. This arrangement, however includes a few slight changes, and includes two pairs of vertical links 31 which straddle the member l6, and which are pivoted at 38 thereto. Pivoted at 39 between the members 31 are the lever members 40 which are pivoted at 4| between the members 21, the levers 40 ext-ending outwardly and being attached at 42 to the foot bearing transverse bars 43. In this structure, the above described links 25 will be received between the members 31.

By manipulating the handles 32, the member IE will rock in accordance with the action as described hereinabove, and by pressing downwardly on the foot bars 43 the leverages exerted through the members 40 will cause th links 31 to assist in the rocking action through the pivotal engagement at 38.

Figures 5 and 6 illustrate a further modified form of the arrangement in which the member 16 and the seats I8 are the same, and wherein a pair of upwardly converging braces 44 are ber l6, which arms 53 straddle the member [6.

Also pivotally attached at 55 to the upper extremities of the arms 53 is the horizontal member 56 which terminates in the handles 51 atr tached thereto.

It will now be seen in this latter structure, that children seated upon the seats l8 can push forwardly and pull rearwardly on the handles 51, whereby the linkages above described will correspondingly through the pivotal engagement at 54, etc., cause the beam it to rock upon the pivot 48.- It will be noted that the members 5| and 53 are at an angle to each other substantially less than a right angle in order to provide the necessary folding action to cause the member IE to rock.

It will not be seen that I have provided all of the advantages mentioned in the objects of my invention with further advantages being readily apparent.

Some changes may be made in the construction and arrangement of the parts of my invention without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.

I claim as my invention:

1. A teetering device comprising a support, a teetering member pivoted centrally on said support, vertical arms pivoted to the support, handles attached to said arms for graspment by person seated at the ends of said teetering member, said arms being attached to said teetering member 4 so that movement of said handles will rock the same, including links pivotally attached to the arms, brackets attached to said teetering member, said links being pivotally attached to said brackets.

2. A teetering device comprising a support, a teetering member pivoted centrally on said support, vertical arms pivoted to the support, handles attached to said arms for graspment by person seated at the ends of said teetering member, said arms being attached to said teetering member so that movement of said handles will rock the same, including links pivotally attached to the arms, brackets attached to said teetering member, said links being pivotally attached to said brackets, foot receiving members attached to said arms.

3. A teetering device comprising a support, a teetering member pivoted centrally on said support, vertical arms pivoted to the support, handles attached to said arms for graspment by person seated, at the ends of said teetering member, said arms being attached to said teetering member so that movement of said handles will rock the same, including links pivotally attached to the arms, brackets attached to said teetering member, said links beng pivotally attached to said brackets, further links pivotally attached to said teetering member, levers pivotally attached to I said further links and to said arms, foot receiving bars attached at the outer extremities of said levers, whereby foot action against said foot receiving members will cause further rocking action of said teetering member.
