Stephen Baker ABSTRACT: A seesaw toy of simplified construction having a central supporting block with an attached downwardly depending vertical sideplate enabling thevblock to be mounted between slats of a slatted bench, the block supporting a semicircular socket on its upper surface, the device including an elongated rocker with end seats; the'rocker having on its underside a semicircular projection which is complementary to and rotatably slidable within the socket'as the rocker is reciprocated in use.

PATENTED AUB31 m1 4 3502.500 SHEET 1' u? 2 INVENTUR.

JOSEPH M. CACKOWSKI fa gum k ATTORNEY SEESAW TOY BACKGROUND OF THE INVENTION The invention relates generally to an easily assembled seesaw toy adapted to be mounted on a slatted bench so that .the toy may be initially disposed in a small package. The

device includes a central supporting block against the side of which is connected a sturdy sideplate. The sideplate depends downwardly from the block whereby it may be deposited between slats of the bench. The rocker assembly comprises a semicircular socket connected to the upper surface of the block, and an elongated rocker having end seats. The elongated rocker is comprised of tubular rods and includes tubular grasping handles. On the underside of the elongated rocker is mounted a semicircular projection which is complementary to and rotatably slides within the socket. As two children are respectively seated on the end seats, they may reciprocate the elongated rocker and the projection will rotatably slide reciprocably in the socket.

SUMMARY OF THE INVENTION AND OBJECTS gated rocker, within a complementary fixed socket on the supporting block.

Another object of this invention is to form the upper, elongated rocker from tubing, which is easily assembled to form the rocker. Further, additional tubing pieces are provided to form grasping handles to add to the safety of the device when m use.

The above and other objects of this invention will become apparent from the following description and drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective, exploded view of the seesaw toy of this invention showing the partsthereof prior to assembly and illustrating the mounting thereof on a conventional slatted bench; t

FIG. 2 is a side elevational view of the assembled device;

FIG. 3 is an enlarged, fragmentary side elevation of the device; and

FIG. 4 is a cross-sectional view as taken along the line 4-4 of FIG. 3.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings which illustrate a preferred embodiment, the upper rocker 10 is essentially formed from four tubular rods 10a, each of which, for example, may be 5 feet long and 1 inch in diameter, the rods being disposed in pairs forming each side of the rocker. The outer ends of rods a each have two successive holes by which they are connected to seats II by bolts 12, provided with suitable nuts, as well as washers if desired. Adjacent to said rod outer'ends, frontally of the seats II. are mounted between a pair of rods 100, short angular grasping handles l3, held in place by bolts 14 which penetrate holes in the rods and handles and which may be provided with suitable nuts.

The inner ends of the tubular rods 10a are interleaved as shown in FIG. I. They are secured in place by bolts 15, eight such bolts being used for example, the bolts 15 penetrating holes formed in said inner ends, and further penetrating the holes 16 formed in centrally disposed upper plate 17, to which they may be fastened by nuts on the underside of plate l7.

Upper plate 17 is provided witha downwardly arched semicircular boss or projection 18 which serves as the rotatably slidable element of the fulcrum or upper rocker assembly. The foregoing described elements substantially complete the upper rocker assembly. Now will be described the lower rocker assembly upon which the upper rocker assembly is deposited for rocking action.

The lower rocker assembly and support comprises the lower plate 20 which has mounted thereon, as by welding 21 or the like, the semicircular socket or cup 22. Socket 22 is fixedand rotatably slidably receives the projection 18 to which it is complementary as illustrated in FIGS. 3 and 4. Upper plate 20 is secured, as by bolts 25 and nuts 26 to the central support 27, illustrated as comprised of two blocks 27a and 27b. In effect, blocks 27a and 27b, when interconnected by the bolts 25, may be considered to form a single large sturdy supporting block.

I As an example, the blocks 27a and 27b may be substantially two-by-four wood pieces. Two such block pieces are provided because a larger or older child may require the added height and sturdiness while for smaller children the block piece 27a may be discarded.

Secured to the side of block 27b is the sturdy vertical sideplate 30, the connection being effected by screws 31 for example. Vertical sideplate 30 depends downwardly from supporting block 27b and provides a mounting leaf for the device.

' The device is adapted for use with a slatted bench 32, the

vertical depending sideplate 30 being simply deposited between two slats whereby the device may rock transversely of the bench. -As an example, vertical sideplate 30 may be about 9 inches by 5 inches, with about 3 inches depending from block 27b, and being of ta-inch thick steel.

It will be recognized from the foregoing that I have provided a simplified, compact, seesaw device, easily knocked down and assembled, and easily installed on a conventional slatted bench or similar structure. I

I have shown a preferred embodiment of myinvention but it is obvious that numerous changes and omissions may be made without departing from its spirit.

What is claimed is:

l. A seesaw toy comprising an elongated rocker, seats at each ind of said rocker, a fulcrum element on the underside of said r cker, a supporting block, a complementary fulcrum ele-,

ment on said block whereby said rocker may rotatably slidably rest 0!:] said block and may rock in seesaw fashion, and a vertical plate connected to said block anddepending downwardly therefrom whereby said vertical plate may be deposited between two slats of -a slatted supporting structure so as to rockably support said my on said structure.

2. A seesaw toy according to claim 1 and wherein said first named fulcrum element comprises a plate secured to the underside of said elongated rocker, and a downwardly arched semicircular projection on the underside of said fulcrum element plate, said complementary fulcrum element rotatably slidably receiving said projection, and said vertical plate being connected to a side of said block.

3. A seesaw toy according to claim 2 and wherein said complementary fulcrum element comprises a semicircular socket, a second fulcrum plate on which said socket is mounted, said second fulcrum plate being mounted on said block, said block being comprised of two separable pieces whereby the effective height thereof may be adjusted, and said vertical downwardly depending sideplate being mounted on the lower of said separable pieces.

4. A seesaw toy according to claim 2 and wherein said elongated rocker is formed form a plurality of tubular rods, one pair of rods forming one side of said elongated rocker, and

a another pair of rods forming the other side of said elongated rocker, and the inner ends of all of said rods being interleaved and interconnected.

5. A seesaw toy according to claim 4 and including an angular rod disposed adjacent to each seat, and mounted between and to the respective pairs of rods, said angular rods serving as grasping handles during operation of said toy.
