Abstract

A swinging playground device includes a swing platform. The swinging playground device also includes a skirt coupled to the swinging platform and fills an area below the swinging platform as the swinging platform moves in a swinging motion.

Claims (28)

1. A swinging playground device, comprising:

a swing platform configured to support a wheelchair; and

a skirt coupled to and extending below the swing platform, the skirt being configured to fill an area below the swing platform as the swing platform moves in a swinging motion.

2. The swinging playground device of claim 1 , wherein a normal of a top surface of the swing platform stays substantially parallel to a vector corresponding to gravity.

3. The swinging playground device of claim 2 , wherein the top surface comprises a wheelchair coupling device.

4. The swinging playground device of claim 3 , further comprising a shock absorbing system configured to decelerate the platform proximate an end of the swing, of the swing platform.

5. The swinging playground device of claim 4 , further comprising a second shock absorbing system configured to decelerate the platform proximate a second end of the swing, of the swing platform.

6. The swinging playground device of claim 1 , further comprising one or more user areas and one or more support bars proximate the user area(s).

7. The swinging playground device of claim 6 , where the one more support bars is coupled to a swing arm, such that forced enacted on the support bar from a user in the user area causes movement of the swing platform.

8. The swinging playground device of claim 1 , further comprising an acceleration assembly configured to assist in initial swinging movement of the swing platform.

9. The swinging playground device of claim 8 , further comprising a second acceleration assembly configured to assist in initial swing movement of the swing platform.

10. A swinging playground device, comprising:

a frame;

a swing platform, coupled to the frame by one or more swing arms;

a user area on the swing platform;

a support bar coupled to at least one swing arm proximate the user area, the support bar being configured to receive a user three to cause the swing platform to swing; and

a skirt configured to fill a space between the swing platform and ground, wherein the skirt comprises a walled structure that fits within a cavity of the swing platform.

11. The swinging playground device of claim 10 , wherein the support bar comprises a friction member configured to hold the weight of the support bar but allow movement of the support bar with an additional force.

12. The swinging playground device of claim 11 , further comprising a user area backer, wherein the user area backer and the support bar are configured to retain a wheelchair in place.

13. The swinging playground device of claim 10 , wherein the skirt is coupled to a rail and moves linearly along the rail as the swing platform swings.

14. A swinging playground device, comprising:

a frame;

a swing platform, coupled to the frame by one or more swim arms;

a skirt configured to move linearly below the swing platform as it swings; and

a shock absorbing system configured to decelerate the swing platform as it approaches a full swing position while the swing platform is swinging.

15. The swinging playground device of claim 14 , wherein the shock absorbing system comprises a pneumatic cylinder.

16. The swinging playground device of claim 14 , further comprising an acceleration device that exerts an acceleration force on the swing platform when a user exerts a swinging force on the swing platform.

17. The swinging playground device of claim 14 , wherein the one or more swing arms couple to the frame at two or more points such that the swing platform remains substantially parallel with a level ground surface.
