Flynn, 179 Avon Court, Northfield, II]. 60093 Filed Sept. 20, 1967, Ser. No. 669,143 Int. Cl. A631: 9/00, 17/00 U.S. Cl. 272-60 9 Claims ABSTRACT OF THE DISCLOSURE An objective of this invention is to provide a folding gym-like apparatus which is easily stored in a compact, packageable, flat form and is quickly assembled and rigidified by an adult without the use of tools or the exercise of any unusual manual dexterity or skill, yet which cannot be disassembled easily by children.
An additional objective of this invention is to provide a portable play unit having a climbing ladder, a swinging bar, a perch seat, climbing holes and crawl-through spaces, while maintaining economy of manufacture.
A still further objective of this invention is to provide a locking and bracing means for a knock-down gym set wherein the stresses and weight forces administered by children utilizing the invention will tend to increase the stability of the unit.
Heretofore, climbing units for children have been primarily of the relatively expensive outdoor type and for maximum enjoyment oftentimes required a permanent emplacement. As a result, gym and climbing sets, although popular with children, have been limited to relatively hard to assemble and disassemble metal frame apparatus. A primary objective of this invention is to provide a gym unit for ready and repeated assembly and disassembly without wear to parts and which, when disassembled, is easily stored in a closet of the average home. The apparatus of this invention then is uniquely suited for use in apartments, homes and classrooms where childrens play space is limited and/ or permanent installation of a gym is undesirable and/or the gym will be used in different places indoors and outdoors. The instant invention satisfies this need in the art.
A further objective of the invention is to provide an extremely portable gym set which, when disassembled, is comprised of individual elements each of which is easily handled by an adult. Further, the individual elements are sized to fit in the trunk of automobiles of standard design.
These and other objects of the invention will become more apparent to those skilled in the art by reference to the following detailed description when viewed in light of the accompanying drawings, wherein:
FIGURE 1 is a perspective view of the assembled apparatus;
FIGURE 2 is a side view thereof;
FIGURE 3 is a top plan view of FIGURE 2 with the top seat removed;
FIGURE 4 is a view showing the slot pattern of the bottom side of the seat portion of FIGURE 1;
FIGURE 5 is a bottom view of a brace member; and
FIGURE 6 is the fold position of one assembly.
Referring now to the drawings wherein like elements indicate like parts, the numeral 10 indicates the gym set of this invention. The principal supporting elements are a pair of folding side assemblies 12 and 14. These assemblies 3,472,509 Patented Oct. 14, 1969 can be manufactured from wood, plywood, flakeboard or particle board having selected characteristics. The side assembly 12 includes a stabilizer 16, a first panel 18 and a second panel 20. The side assembly 14 includes the stabilizer 22, a third panel 24 and a fourth panel 26. The stabilizer 16 is secured to panel 20 by hinges 28 and the panel 18 is secured to stabilizer 16 by hinges 30. Likewise, the panel 24 is secured to stabilizer 22 by hinges 32 and the panel 26 is secured to the stabilizer 22 by the hinges 34. As best seen in FIGURE 6, the stabilizers and the panels are foldable together in parallel relationship for storage. They also are readily pivoted to the positions shown in FIG- URES 1, 2 and 3 to provide a stable support.
The stabilizer and the side panels slope upwardly and inwardly from their lower base lines to upper ends which, except for handle portions mentioned hereinafter, terminate in a common plane indicated by the numeral 36. Therefore, when panels 24 and 26 and 18 and 20 are respectively placed in common vertical planes and stabilizers 16 and 22 are placed perpendicular to these common planes, the upper ends form two generally T-shaped configurations in the plane 26. A seat member 38, having corresponding T-shaped groove patterns 40 and 42, unifies the panels and stabilizers by snugly receiving the T-shaped configurations in plane 36. The seat 38 is also slotted at 44 and 46 to receive a pair of hand grips 48 and 50 which extend upwardly respectively from panels 18 and 24. The hand grips are apertured as shown in FIGURE 1 for easy gripping by a child utilizing the gym set.
At their lower ends, panels 20 and 26 are formed with rectangular openings 52 and 54. A bottom brace 56 has grooves 58 and 60 formed in the bottom surface thereof. A second set of grooves 57 and 59 in the depth-wise or vertical direction respectively intersect the grooves 58 and '60. The grooves 57 and 59 engage the bottom ledge openings 52 and 54 and the grooves 58 and 60 the side edges thereof. The bottom brace 56, together with seat 38, stabilizes the panels 20 and 26 with respect to one another. The lower ends of panels 18 and 24 are provided with similar openings 57 and a bottom brace 62 having grooving similar to that of brace 56. The lateral grooves 58 and 60 of the bottom braces 56 and 62 are longitudinally spaced from one another slightly less than the distance between the seat slots 44 and 46. This causes the side assemblies to be closer at their bases than at their upper ends causing additional pressure to be placed on the stabilizers.
The panel 20 is formed with a series of aligned apertures 64. The panel 26 is equipped with corresponding aligned apertures 66. A plurality of wood ladder rungs 68 having a greater length than the distance between panels is received by the corresponding apertures. Each rung is of suflicient length to provide an extension 70. Of course, there is also an extension on the other side extending beyond the panel 26. These extensions or end portions are drilled with transverse bores 72 therethrough. Interposed along the line of openings 66 is a pair of eyelets 73 and 74. The ladder rungs are readily but securely afiixed to the side panels by inserting a metallic rod 78 respectively through each of the bores 72 and the eyelets 73 and 74. A flange 80 at the upper end of the rod prevents the rod from slipping through and from being removed by children. The rod also prevents the rungs from revolving to insure a more stable ladder.
The panels 18 and 24 have opposing apertures 82 through which a pull-up bar 84 is inserted. A pair of removable and resilient grips 86 and 88 maintains the bar 84 in position between the panels while allowing the bar to revolve freely for swinging.
In storage, the side assemblies 12 and 14 are folded upon themselves as shown in FIGURE 6. The remaining units of the invention; namely, the elongated seat 38, the bottom braces 56, the rungs 68 and the rod 78, are easily stored With the side units. In assembly, the two side units are spaced apart at an estimated distance. Since the units are three-paneled, they readily stay in position. The bottom braces 56 can then be inserted and the positions of the side panels and stabilizer of each side assembly are rigid with respect to each other. The hanging bar 84 and the rungs 68 are quickly slipped into their appropriate position and the rod 78 slipped through the holes 72 and eyelets 73 and the top seat is placed in position by slightly varying the distances between the side units until their upper ends are firmly received in the groove patterns 4% and 42. It can be seen that a rigid, durable and attractive gym-like set is ready for the play of children in less than a minute. The disassembly procedure merely consists of a reversal of the above steps.
It should also be noted that the gym set is enhanced by the provision of climbing holes 90 in panels 18 and 24 and the provision of crawl-through openings 92 in panels 20 and 26. These openings not only reduce the weight of the side units but provide a diversification of play to the using children. Since the primary components of the gym set are of wood or wood-based products, the various openings, grooves and apertures are easily formed by workman in the average wood-working shop.
