This invention relates to a device for isolating a por
tion of the area of a ?oor, and more particularly to a
special barrier for an area of a ?oor to isolate that area.
Patented Sept. 4, 1962
also joined at right angles to each other forming a gen~
erally U-shaped isolated area 24 on floor 12 which has
an open side 26 for ingress and egress of the motor
All of the strips may be made of numerous materials.
For instance, the strips from which the barrier is made
may be constructed from various tubular plastics e.g.
polyethylene, metal, rubber either natural or synthetic,
or any elastomeric substance.

This invention provides a- barrier constructed of a
plurality of joined strips, designed to be attached to the
floor to isolate an area thereof wherein one or more
motor vehicles may stand until the ice and snow melts
from the undercarriage. The barrier prevents the melted
snow from running over the entire ?oor and causing
puddles which are not only annoying but actually danger
ous, especially upon re-freezing.
Another object of the invention is to provide a barrier
for a portion of the area of a floor, wherein there are
means by which the barrier may be used for ?ushing the
isolated area. These means consist preferably of a water
passage in the strip that forms the barrier, plus a number
of ori?ces directed inwardly of the isolated area. By
attaching a conventional hose to the barrier, the passage
may be supplied with water under pressure which ulti
mately passes through the ori?ces and sweeps across the
floor area isolated by the barrier.
These together with other objects and advantages which
will become subsequently apparent reside in the details
of construction and operation as more fully hereinafter
described and claimed, reference being had to the ac
companying drawings forming a part hereof, wherein like
numerals refer to like parts throughout, and in which:
FIGURE 1 is a diagrammatic top view showing the
barrier in use.
FIGURE 2 is a sectional view taken on the line 2-2
of FIGURE 1.
FIGURE 3 is an enlarged sectional view taken on the
line 3-3 of FIGURE 1.
FIGURE 4 is a cross-sectional view showing a modi?
cation of one of the strips that forms the barrier.
FIGURE 5 is a cross-sectional view showing another
?at upper surface 28 and an approximately flat bottom
surface 36 which is cemented in place on floor 12 around
its side 32 and an upstanding side 34. A longitudinal pas
sage 36 is in strip 116 and joins to an identical passage in
strips 18 and 20. The passage 36 is closed at its ends
but is in communication with a nipple 40 or some other
type of hose coupling so that a source of water under
pressure may be operatively connected therewith to sup
ply passage 36 with water. A number of ori?ces 42 are
in strip 16 and they are in communication with passage
36 so that when water under pressure enters the passage
36, it is discharged through the ori?ces. The ori?ces are
directed inwardly toward area 24 so that the water issuing
therefrom will be swept across this area for the purpose
of cleaning it.
FIGURE 4 shows strip 50. This strip differs from
strip 16 only to the extent that passage 52 therein is
located in the center of the strip instead of to one side
thereof. Further, strips 16 and ‘50 each have sloping
surfaces at the top thereof to facilitate walking or riding
over the strips. By having the smooth bevel, persons
are less likely to trip over the strip, even though this likeli
hood is remote in view of the small thickness of the
strips. They need only be an inch or two inches thick
at the highest points.
A further modi?cation is shown in FIGURE 5 where
In this form of
the invention, as in all other forms, ori?ces may be pro
vided in registry with passage 56 so that water may be
issued in jet streams therefrom to sweep across area 24.
Alternatively, each of the forms of the strip may be
manufactured without passages and without ori?ces but
this would be at the expense of the capability of the
