The present invention relates to closures and
supporting and operating means therefor, and has

Whose upper end is associated with a novel struc

tractible trough-like adapter and closing unit-i5.
To be more speci?c, this ‘part it is channel
shaped in cross-sectional form with its side walls .15
slidable through the slots formed in the part Hi.
Said .part it functions as a closure to maintain a
constant closing action between the upper end
of the door and the horizontal casing it of the

frame structure.

Attention is now directed to the structure in
terposed between the floor and the bottom of the
‘ door.
This comprises an especially designed ?x
ture unita'rily denoted by the numeral 20. It is
screwed or otherwise secured to the ?oor and in- 35
cludes a segmental base plate 2i having a vertical
stabilizing and attaching upstanding rim portion
22. The rim portion merges into duplicate seg- ‘~
mental risers or tracks it disposed on opposite
sides of the door in the proper path of swing of go
said door. The door is provided with a wear plate '
2t and with a cup or receptacle 25 to accommo
date the castor roller or ball it. This provides a
tracmng element and is ridable on the track
?anges t3. Inasmuch as the ?anges are tapered 45
to the degree shown, they are in e?ect cam ele
ments of proper segmental form to allow the door
to rise and fall as its swings to open and closed
position. That portion of the base plate 2! be
tween the adjacent ends of the so-called tracking so
cams 23 is preferably formed with a keeper recess
forming a receiving pocket 2‘! to accommodate
the ball 26 in its normal resting position, in which
position the door is then closed.
,
Attention now comes to the hinge rod or pintle 55

18, this being located in a bore in the door hav
ing its lower end ?xedly attached to the base
plate ii. The upper end is saddled in the eye
portion, 20 of the adapter bracket 80. An ap
propriate fastening 3i secures together the com
plemental portions of said bet and serves
to‘ bind the hinge rod or pintle 2B rigidly in
place. Thus, we have a perpendicular ?xed rod
28 secured to the fixture 2i? and the bracket as
10V and parallel to the adjacent casing it of the door
frame. The door itself swings freely on thisrod
as a pivot.

In operation as the door is swung in either
direction, it is obvious that the anti-friction ball

the door for raising and lowering movement
therewith as a unit.
