Speci?cally describing the illustrated embodiment of
the invention, the barrier comprises a plurality of base
pieces A and a plurality of rail or fence sections B.
Preferably, the base pieces are identical to each other
and the rail sections B are identical to each other so that
any one or more base pieces can be easily and quickly
assembled or associated with any one or more of the rail
It is desirable to releasably lock the rail sections to
the base pieces to prevent unauthorized tampering with
or movement of the rail sections, and for this purpose,
each stile 7 may have a notch 11 therein extending
throughout a small portion of the circumference thereof
to expose a portion of the stud with which the stile is
telescopically associated as shown in FIGURES 4 and
5; and a clamp is applied to the stile with a portion

As shown, each base piece comprises a plate, prefer 65 thereof frictionally gripping said stud. As shown, the
clamp comprises two complemental sections 12 and 13
ably formed of cast metal and of substantialthickness
having their end portions 14 separably secured together
as shown in FIGURES 4 and 6, and being approximately
T-shaped in plan so as to provide two arms 1 and 2 in

While the invention has been shown as embodying
certain structural details, it will be understood that the
construction of the base pieces and the rail sections may
be modi?ed and changed within the spirit and scope of
the invention.

3. A portable knock-down barrier as de?ned in claim
2 wherein there are three studs rigidly projecting from
the top side of the base plate in spaced parallel relation
to each other at the juncture of the arms of the T-shaped
plate with each at one apex of an imaginary triangle one

plurality of elements and each rail section havinga plu
rality of parts each telescopically coactive with one of
said elements of any one of said base pieces to separably
connect said rail sections to said base pieces, each base
piece comprising a T-shaped plate with two arms in sub
stantial alignment with each other, at least two of said
elements being disposed in a common vertical plane
parallel with said two arms that are in alignment with
each other.
2. A portable knock-down barrier comprising a plu
rality of base pieces to set on a support surface, and a
plurality of rail sections, each base piece having a plu
rality of elements and each rail section having a plurality
of parts each telescopically coactive with one of said
elements of any one of said base pieces to separably con
nect said rail sections to said base pieces, each base
piece comprising a T-shaped plate with two arms in
substantial alignment with each other, said elements on
the base piece comprising elongated studs rigidly secured
association with any of said studs.
4. A portable knock-down barrier as defined in claim
1 wherein each base piece has a notched perimetral
?ange projecting from the bottom side of the base piece
and beunding- a recess in the bottom side of the base
piece to engage said supporting surface and restrain
movement of the base piece horizontally on said support
surface.
5. A, portable knock-down barrier comprising a plu

of rail sections each having at least ‘two stiles each of
which comprises tubular material having an open end for
telescopically slidable association with any of said studs
and also has a transverse opening, and a clamp encircling
said stile with a portion frictionally engageable through
said opening in the stile with the telescopically associated
stud to. releasably lock together the rail section and the
base piece,
