6 Claims.

This invention relates to improvements in collapsible 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 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 unskilled persons.

The invention is capable of being variously embodied 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 substantially equal to the width of the metallic elements, mainly channel bars, of which the structure 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 illustrating 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 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 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.

The terminal portions of the arms of said member 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 suitable type and shape. Said frame 3 is adapted to carry the sign to be displayed or may constitute 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 channel bar, having outwardly projecting flanges,

as shown in Fig. 4. The pivoted connections between the arms 4 (which are the equivalent of legs) and the U-shaped member I are effected by means of rivets I. Spaced from each of said rivets 6 is an opening in each of said arms. 4

which is adapted to receive a pivot member 'I extending 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 oiiset 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 spacing 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 inclusive when the several component parts of the structure are disposed as shown in Fig. 1. The several connections of the supports 5 and l0 with the member I are vertically aligned with each other and are so held by the bolt Il when the middle portions of said supports 5 and I0 rest upon the side-walk. A

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 supporting 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 disposed in a carton of a Width substantially equal 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 the arms or legs 4 and 9 may be omitted if de- 40 sired, said arms constituting supporting legs 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 extending 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.

The legs Il, also composed of channel bars having their flanges disposed outwardly, are secured 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 II 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 are disposed inthe full line position of Fig. 6, the upper end portions of the legs I1 are swung clockwise to cause the studs I9 to pass into channels of the bars I3 until said studs I9 engage the studs I6, as shown in Fig. 7. Thesaid studs I' constitute sto-p formations which will prevent become disposed in the position shown in dotted lines in Fig. 6 and in full lines, inkrFig.. 5. Tl1e,saicl -L studs IB and I9 become inter-engaged bymeans of their overlapping flanges 22 to prevent relative lateral movementsof thelegs. I3.andr I'ivand thus effect a strengthening of the structure as will be obvious.

In .the instance illustratedthe legs. I3 lmay be arms of a U-'shaped member such as is shown in Figjlgwhereas the. legs/*|31 must befree of such cros"s-bar connection,.to',render thern capable of being folded upwardly so that their longer ends are flushwith they sidelfedges of the ,upper portions o-f the arms of the member Waiter the legs I3 have.A been similarly,,swungY upwardly .on .their pivolts. .20, whereupo-naall will be. disposed flush With-.the,members I4 and I5.','

The pivot vI8 necessarily includes ya spacing sleeve 2 I. shown in,Fig. 8 to'v enable said legsyto be folded .aslastabove' described.

An advantage ."off .the structure ^of .Figs-.59 inclusive', over the. structure o-f Figs. 144, resides in the fact thatthe personsetting up the sign i'sinot req'uiredto insertl any bolts or screws and this advantage, `of courseis pre/sent ,also in collapsing the structure.
