9 Claims. (Cl. 125) The object of this invention is to provide an easel, but more particularly in the type which is especially adapted for maintaining in open or extended .position broadly, posters and similar display or advertising material especially in the form of flexible webs or sheets and supporting said extended display material.
Another object is to providean'easelwhichcan be produced at relatively low cost, and which shall be light in weight and which can be readily fashioned from'such pieces of metal, as the channeled ribs commonly used in the manufacture of umbrellaiframes, 'or wires or rods, of round, oval, tubular, or other type of'curviform cross-section.
A still further object is to provide an easel which can be shipped in the smallest possible space, and which whendisassembled or folded can be shipped in a-so-called mailing tube of very small diameter and of a lengthnot greater than the shortest dimension of'the' display material.
Still another object of the invention is to provide an easel which is rug ged andcapable of supporting sheets or the like of relatively great weight and area. This embodiment "comprises a triangular base portion, which portion comprises a forward stretcher element which is flexible, a leg element pivotally 'connectedto the forward stretcher element, and a brace element formed of a plurality 'of sections hingedly connected to said previously named elements, said base portion having a resilient extension on said forward element which ispreferably pivotally attached thereto.
These and other objects of our invention will be evident from the following specification when read in conjunction with the accompanying drawing, in which Fig. 1 is a side elevation of an easel, illustrating one embodiment of our invention shown in combination with a poster or the like in the form of a flexible web or sheet operatively supported thereby.
Fig. 2 is an enlarge-d fragmentary view of the extremity of the easel which engages the material to be displayed.
Fig. 3 is a section on the line 3-3 of Fig. 1.
Fig. 4 is a section showing the arrangement whereby each end of the easel detachably engages a transversely extending stiffening member with which the material to be displayed is preferably provided; and I Fig. 5 is a side elevational view of the easel in folded and almost completely collapsed form for storage and shipping purposes.
The easel here shown comprises a substantially triangular base sectionformed of a forwardly positioned element ID, a rearwardly extending leg element H pivotally secured to said forward element at l2, and a lower substantially horizontally extending spacer element which comprises sections .53 and i l, the opposite ends of which are pivotally connected at l6 and I1 to said forward and leg elements, respectively, while 'the adjacent end portion of said spacer sections A free *5 are pivotally connected together at l5. end portion 58 of oneof said sections normally 7 extends over and in contact with the other of said sections, so as to maintain said sections in normal alignment.
Each of said elements is of channeled crosssection as clearly shown in Fig. 3, and they are preferably formed in amanner similar to 'that employed in the construction of umbrella frames.
"The lower end 2! of the forward element [0 is preferably flattened so as to engage a transverse- 15 stiffening member 22 secured to the lower edge portion of the normally planarsheet or web23,
"the opposite-end of said sheet or web being provided with a transversely extending stiffening member 24, to which is detachably secured"a=':20
the upper free projecting portion 28 of the for- Ward element it. Adownwardly projecting portion 29' of said extension element overlaps and normally engages the projection 28 to limit the forward angular movement of said elementffZB with respect to said lower forward element [0.9.9
'From the position ofthe easel as sh'own'in Fig. 1, it may beflex-ed so as to permit the withdrawal of members 2! syn-(1 25 from thetransversely stiffening extraneous members 22 and 24 respectively, after which the stretcher sectiohsgg I3 and M are folded with respect to each other,
and the extension element 26 is moved angularly rearwardly with respect to the forward base ele- 'ment HL'flrst throughthe intermediate position indicated by Fig. 5', and then into a totally col-e14 lapsed'structure for storage, or for inserting the same into a slender mailing tube or the like,
either alone or with the sheet or Web 23.
