6 Claims.
This invention relates to improvements in col
lapsible sidewalk sign supports which are cheap,
durable and efficient and which may be folded
to occupy a very small space so as to enable them
5 to be packed and shipped in very flat cartons.
A further object of the invention is to provide
a device of this character which can be very
easily set up and collapsed, respectively, by un
` skilled persons.
The invention is capable of being variously em
bodied and in the accompanying drawings there
are illustrated two suitable embodiments thereof.
In said drawings:
Fig. 1 is a perspective view of the preferred
l5 form of embodiment of the invention.
Fig. 2 is a fragmentary front elevation of the
same when collapsed or folded up ready to be
inserted'into a flatl carton of a depth substan
tially equal to the width of the metallic ele
20 ments, mainly channel bars, of which the struc
ture is composed.
Figs. 3 and 4 are fragmentary detail sectional
views on an enlarged scale taken respectively on
the lines 3-«3 and 4-4 of Fig. 1.
Fig. 5 is a fragmentary side elevation illus
trating another embodiment of the invention.
Fig. 6 is a side elevation of the same showing
the parts in position in full lines preparatory to
disposing them in the position of Fig. 5 and in
30 the dotted line position of Fig. 6.
Figs. '7 and 8 are fragmentary detail sectional
views on an enlarged scale taken, respectively,
on the lines 'I-l and 8-8 of Fig. 5.`
Fig. 9 is a fragmentary detail perspective view
35 of the upper end of one of the supporting legs of
the structure.
Referring first to Fig. 1, it will be noted that
the sign support comprises the U-shaped member
I composed of a strip of channel bar, preferably.
(o1. 40-12'5)
which is adapted to receive a pivot member 'I ex
tending through the same and through a spacing
sleeve 'Ia and the terminal end portion 8 of an
arm S of the U-shaped support I U. The said
terminal end portion 8 of each of the arms 9 is 5
oii‘set slightly inwardly from- the body portions
thereof and the arms 9 of the member I0 are thus
pivotally secured to the arms 4 of the member 5.
Each of the arms 9 is pivotally secured between
its ends to the U-shaped member I by means of 10
a suitable bolt II which extends through a spac
ing sleeve I2 disposed between the arm 9 and an
arm of said U-shaped member I through which
the bolt I I projects.l
The bolt I I is removable digitally to effect col- 15
lapsing of the structure shown in Figs. 1_4 inclu
sive when the several component parts of the
structure are disposed as shown in Fig. 1.
several connections of the supports 5 and l0 with
the member I are vertically aligned with each 20
other and are so held by the bolt Il when the
middle portions of said supports 5 and I0 rest
upon the side-walk.
When the member I is vertically disposed, the
View of the sign carried by the member 3 is un- 25
obstructed by any portion of the respective sup
porting members 4 and I D and is only slightly
obstructed, when viewed from an angle, by the
arms of the supporting members 5 and I0.
By removing the bolt I I, the supports 5 and ID 30»
are folded so that their side edges are aligned
with each other and with the side edges of the
arms of the member I and the side edges of the
member 3, thus enabling the device to be dis
posed in a carton of a Width substantially equal 35
to the width of said arms and middle portion of
the member I and of the members 5 and Ill, as
shown in Fig. 2.
Obviously, the middle or crossbar portions of
40 The terminal portions of the arms of said mem
the arms or legs 4 and 9 may be omitted if de- 40
ber I are offset inwardly from the main portions
of said arms as at 2, and to said offset portions
2 there is pivoted a swinging frame 3 of a suit
able type and shape. Said frame 3 is adapted
45 to carry the sign to be displayed or may consti
tute a permanent portion of such sign.
Pivotally secured to the arms of said U-shaped
frame I between the ends of the latter, are the
arms 4 of a U-shaped support 5, also composed of
sired, said arms constituting supporting legs
50 channel bar, having outwardly projecting flanges,
tending outwardly and each thereof is equipped 50
between its ends with a stud I 6 shown in detail in
Fig. '7 which is equipped with an enlarged head.
as shown in Fig. 4. The pivoted connections be
tween the arms 4 (which are the equivalent of
legs) and the U-shaped member I are effected
by means of rivets Iì. Spaced from each of said
55 rivets 6 is an opening in each of said arms. 4
whether connected, as shown, or not.
In the structure of Figs. 5-9 inclusive, the legs
I3 are pivotally secured at their upper ends to
points between the ends of the arms of the mem- 45
ber I4, which corresponds with the member I ’
and which carries a member I5 corresponding
with the member 3. Said legs I3 are composed
of channel bars disposed with their flanges ex
The legs Il, also composed of channel bars
having their flanges disposed outwardly, are se
cured between their ends to the lower end por- 55
tion of the member I4 by means of suitable pivot
members I8. Each of the legs I‘I is provided at
its upper end with a stud I9 mounted upon the
rear face of the said leg and which is spaced from
the pivot I8 the same distance as the pivotal
connection 20 between each leg I3 and said
member I4 is spaced from said pivot I 8.
When the parts, I3, I4 and I1 above described

legs being engaged with the first-named pair of
legs at points spaced from the pivotal connec
tion of the latter with said carrier.
