Abstract
Abstract The upright supports for holding a horizontal bar are formed of plastic tubing which is split lengthwise, and a piece of doweling is inserted in each upright tube. The doweling has an O.D. greater than the I.D. of the split tubing, and the plastic tubing frictionally engages the doweling. Projecting through each slit is a horizontal pin connected to the doweling. These two horizontal pins support the horizontal cross bar. The game is played by starting the cross bar high and then steadily lowering it by manually sliding each dowel in its split tube, until the players can no longer pass under it, supported by their feet alone.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
105 words
Limbo game apparatus of the type wherein uprights support a cross bar comprising: a. a pair of vertical uprights of resilient tubing, each having a longitudinal slot; b. a slider disposed inside each tubing upright and having a cross section of greater dimension than that of the interior of the split tubing so that the tubing and slider frictionally engage each other; and c. a pin projecting from each slider through the respective slot in the uprights for support of a cross bar and for manipulation of the slider for moving the slider up and down to support the cross bar at a selected height.
Claim 2
Dependent Claim
105 words
Limbo game apparatus of the type wherein uprights support a cross bar comprising: a. a pair of vertical uprights of resilient tubing, each having a longitudinal slot; b. a slider disposed inside each tubing upright and having a cross section of greater dimension than that of the interior of the split tubing so that the tubing and slider frictionally engage each other; and c. a pin projecting from each slider through the respective slot in the uprights for support of a cross bar and for manipulation of the slider for moving the slider up and down to support the cross bar at a selected height.
Claim 3
Dependent Claim
15 words
Limbo game apparatus as set forth in claim 1 wherein the tubing is plastic tubing.
Claim 4
Dependent Claim
19 words
Limbo game apparatus as set forth in claim 1 wherein the tubing is round cross section polyvinyl chloride tubing.
Claim 5
Dependent Claim
17 words
Limbo game apparatus as set forth in claim 1 wherein the slider is a length of doweling.
Claim 6
Dependent Claim
47 words
Limbo game apparatus as set forth in claim 1 wherein the tubing is of the glue joint type, each upright has a base for support, and each base has secured thereto a coupling open to the top to form a socket for removably receiving a tubing upright.
Claim 7
Dependent Claim
36 words
Game apparatus as set forth in claim 1 wherein height graduations are marked on the uprights adjacent to the slit so that the user can quickly move the pin of each upright to the same level.
Claim 8
Dependent Claim
21 words
Game apparatus as set forth in claim 1 wherein the slit walls also engage the pin to frictionally engage the pin.
Claim 9
Dependent Claim
101 words
Limbo game apparatus of the type wherein uprights support a cross bar comprising: a. a pair of vertical uprights of rEsilient tubing, each having a longitudinal slot; b. an elongated slider disposed inside each tubing upright and having a cross section approximately the same as the interior cross section of the slit tubing for guided movement in the tubing; c. and a pin projecting from each slider and through the slot and having a dimension transverse to the tubing of a size to cause frictional engagement with the tubing sufficient to support the weight of one end of a cross bar.
Claim 10
Dependent Claim
101 words
