My invention pertains to a childs gymnasium apparatus;
An object of my invention is to provide such an apparatus which can be used as a bouncing spring board, and which spring board can be changed as desiredto a slide, or a ring apparatus.
A further object of my invention is to provide means for changing to the alternate forms in a unit construction without requiring any extra parts, or the like.
A: further object of my invention is to provide such a/spring board simulating riding action on a horse, with certain arrangementsfor providing a spring urged bouncing action.
A further object of. my invention is to provide means cooperant with: the spring board arrangement so that it willreadily provide the, slide features when changed to thesslide form.
A further object of my invention is to-provide the above mentioned objects. in. a simple construction.
With these, and other objects in view, my invention consists in the construction, arrangement, andcombination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully setforth, pointed out in my claims, and illustrated inflthe accompanying drawings, in which:
Figure 1 is a side elevation of the when used as a bouncing board,
Figure;2 is a plan view ofvFigure 1,
Figure 3 is:a rear end view oi Figure 1,,
Figure 4 is a sectional detail, taken along, the lines 4-4 of Figure 3,
Figure 5 is a view of the arrangement when used as a slide,

Figure 7 is a slightly modified form of the arrangement;
Figure 8 is a rear view of Figure '7, and
Figure 9 is a view of the arrangement shown in Figure '7 when used as a slide.
I have used the character to designate a pair of vertical posts having the transverse base H attached thereto. A pair of spacers I2 are positioned adjacent to the upper ends of the posts in and attached at 13 to the spacers are a pair of side stair members l4 between which are attached the flat steps I and attached across the bottom of the members 14 is a further member l6. Received through the members [2 and the posts I!) and the members l2 and I4, and which is securely held in place by means of the arcuate bands l9 which are retained by means of the arrangement bolts 20 which pass through the members it; Received between the members 14 is an extending portion 2! of the substantially lengthened flat: board 22, the shaft [*1 being attached thereto by means of the clamps 23. The board 22 includes a pair of side members 2-4, and continues into! a seat portion 25 to which is attached at26 the upwardly extending bar 21 which terminates inthe transverse handle 28; Attached at 29 Tea rope or other loop 30 and also attached su b-- stantially at the point 29 are apair of ropes 3| which are attached at 32 to the rings 33. A pair of openings 34 are provided at the rear end of the board 22, and received within suitable openings 35 in the posts'and spacers are a pair-of lengthened pegs 36 which: are attached to the chains 3'! which chains in turn are attached to the posts.
Attached inwardly to either post H! by means of the brackets 38 are a pair of cylinders 39. The
brackets 38 are rigidly attached to theposts 1 0" by means of a pair of bolts 40. A pair of furtherequally spaced openings 4| are also provided in the posts 10. Received within the cylinders 39 are,
strong helical compression springs 42 which. re ceive the extending portion 43 of the; members 44 which are threadably engaged at 45 with the rear end ofthe cylinder 39. include slots. The forward. ends of the cylin.
ders 39 are open, and received within this opening 41 when the arrangementis used inthe springboard position are the substantially arcuate bars 48 which terminate in the ball portions 4.9, such.
the cylinder and will be completely unrestricted during any movement of the board.
Figure 1 illustrates the use of the arrangement as a bounce board, or where a child simulates the action of horse riding. The child is seated on the seat 25 with his feet in the rings 33, and grasping either the handle 28 or the loop 30 as desired. As the child bounces up and down on the seat, the arms 48 will alternately compress against the spring 42 and release, thereby providing a pronounced spring action which carries the child upwardly and downwardly in a realistic manner. The spring is normally securely held on the portion 43 and the tension of the spring can be adjusted by turning the member 44 through the agency of the slot 46. In some cases it may be The members" 44 the openings 34.
desired to'tilt the board 22 or elevate the seat 25, which is accomplished by moving the cylinders 39 to the right as viewed in Figure 4, until the bolts 40 can be registered with the further openings 4|, the equal spacing of the openings providing as many as three adjustments. In this manner the board can accommodate larger children, or can be varied in its position to suit any desired conditions.
When used as a slide, the entire board is swung over in the direction of the arrow M to the posiwithout any projections so that the child can be seated at the upper end for sliding. In this type of structure the spacer members I2 will not be tion as shown in Figure 5, with the seat portion then resting on the floor surface. The child can then climb the steps if), and thence grasping the bars 48, place himself between the side members 24 and slide down the slide thus formed, this side of the slide being suitably smooth for this purpose.
Figure 6 shows the arrangement as used asian exercising device, wherein the board 22 is elevated to a substantial angle until the openings 34 register with the openings 35, and the pegs 36 are. then pushed inwardly until they pass into The arrangement is then in rigid position as shown, and the child will then grasp the rings 33, and swing, etc., from the same.
The straps 19 provide means for convenient assembling after packaging of the device, although it will be understood that the members can be attached in any suitable manner.
Figures 7 to 9 inclusive show the same arrangement as above described, with the exception that the spring members are altered as will now be described. The balance of the structure however, is identical to that mentioned above. In this latter modification the cylindrical members 39, springs 52, and arms :38 are not used,'ancl instead a pair of springs 52 are attached at their upper ends to the portions 2| of the board, being solidly bolted or otherwise attached at 53 thereto. The springs 52 pass over the end of the board and are retained by means of the substantially U-shaped keeper 54, and aresolidly attached at 55 to suitable bolts or the like to the inside of the vertical postsllly :It should be notedalso that in this modification, the shaft I! is mounted at a slightly higher elevatio'nin' order to'secure sufficient leverage action of the spring with respect to the end of the board,
and itwill' also be noted that the openings 3:3 are located atthe end of the board to accommodate the position shown in the dotted structure Figure 7 wherein the arrangement is used as more completely shown in Figure 6. i
In this latter arrangement also, the springs 52 will be under tension when the child is bouncing on the board, or when the arrangement is as.
shown in Figure '7. When the arrangement is swung over tothe slide position shown in Figure 9', the springs 52 will then be completely beneath the board and providing an unrestricted portion.
It will now be seen that I have provided all of the various 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 purpo se of my invention, and it is my intention to cover by my claims any modified forms of structure or use oi mechanical equivalents which may be reasonably included within their scope.
