Abstract
Abstract A hitch for attachment beneath the bumper of a powered vehicle is disclosed. The tow bar of the hitch is held in a retracted position by a pivotal wall locked in place, or the tow bar is clamped in an operational position by the same pivotal wall locked in place. The retractable hitch is completely functional by moving a handle beneath the hitch and rotating the tow bar as appropriate.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
212 words
A hitch, comprising: a frame; a tow bar pivotally attached to said frame; first means, attached to said frame, for stopping pivotal movement in a first direction of said tow bar; second means, attached to said frame, for stopping pivotal movement in a second direction of said tow bar; and means for locking said tow bar against one of said first and second stopping means, said locking means including a handle, said handle being rotatable about first and second orthogonal axes to one of lock and unlock said locking means; said frame including first and second partial enclosures, said first stopping means including a ball attached near an end of said tow bar and a first wall forming one side of said first partial enclosure, said ball moving into said first partial enclosure and contacting said first wall to stop pivotal movement of said tow bar in the first direction, said second stopping means including a second wall forming one side of said second partial enclosure, said tow bar moving into said second partial enclosure and contacting said second wall to stop pivotal movement of said tow bar in the second direction; whereby said tow bar is rotatable between first and second positions on operation of said locking means with said handle.
Claim 2
Dependent Claim
212 words
A hitch, comprising: a frame; a tow bar pivotally attached to said frame; first means, attached to said frame, for stopping pivotal movement in a first direction of said tow bar; second means, attached to said frame, for stopping pivotal movement in a second direction of said tow bar; and means for locking said tow bar against one of said first and second stopping means, said locking means including a handle, said handle being rotatable about first and second orthogonal axes to one of lock and unlock said locking means; said frame including first and second partial enclosures, said first stopping means including a ball attached near an end of said tow bar and a first wall forming one side of said first partial enclosure, said ball moving into said first partial enclosure and contacting said first wall to stop pivotal movement of said tow bar in the first direction, said second stopping means including a second wall forming one side of said second partial enclosure, said tow bar moving into said second partial enclosure and contacting said second wall to stop pivotal movement of said tow bar in the second direction; whereby said tow bar is rotatable between first and second positions on operation of said locking means with said handle.
Claim 3
Dependent Claim
51 words
A hitch in accordance with claim 1 wherein said locking means includes means for covering said second partial enclosure when said ball is in contact with said first wall of said first partial enclosure, said covering means preventing debris from filling said second partial enclosure and hindering operation of said hitch.
Claim 4
Dependent Claim
47 words
A hitch in accordance with claim 2 wherein said covering means includes a pivotal third wall and an edge of said tow bar, said third wall being pivotal to allow rotation of a second end of said tow bar into and out of said second partial enclosure.
Claim 5
Dependent Claim
139 words
A hitch, comprising: a frame including first and second walls; a tow bar having opposite side edges, said tow bar being pivotally attached to said frame for movement between operational and retracted positions; a ball attached to said tow bar; a third wall povitally attached to said frame; and means for locking said third wall to prevent said tow bar from pivoting, said tow bar in the operational position being clamped at said opposite side edges between said second frame wall and said pivotable third wall, respectively, said tow bar in the retracted position being held at said ball and one of said side edges by said first frame wall and said pivotable third wall, respectively; whereby said locking means locks with said pivotable third wall to hold said tow bar in one of said operational and retracted positions.
Claim 6
Dependent Claim
139 words
A hitch, comprising: a frame including first and second walls; a tow bar having opposite side edges, said tow bar being pivotally attached to said frame for movement between operational and retracted positions; a ball attached to said tow bar; a third wall povitally attached to said frame; and means for locking said third wall to prevent said tow bar from pivoting, said tow bar in the operational position being clamped at said opposite side edges between said second frame wall and said pivotable third wall, respectively, said tow bar in the retracted position being held at said ball and one of said side edges by said first frame wall and said pivotable third wall, respectively; whereby said locking means locks with said pivotable third wall to hold said tow bar in one of said operational and retracted positions.
Claim 7
Dependent Claim
88 words
A hitch in accordance with claim 4 wherein said locking means includes a handle pivotally attached to said pivotable third wall and an angle member attached to said handle, and wherein said frame includes a fourth wall extending parallel to said tow bar, said angle member having one leg spaced from said handle to allow said fourth wall to fit between said handle and said one leg of said angle member thereby locking said pivotal third wall which thereby holds said tow bar in operational and retracted positions.
Claim 8
Dependent Claim
36 words
A hitch in accordance with claim 5 wherein said locking means includes means for biasing said handle and said angle member about the pivotal axis of said handle toward a holding position of said fourth wall.
