' -2 claims.l (o1. L11i-1.25)
' Granted nae'r the act of March amended April 30, 192s; 37o o. G. 757) l The invention described herein may be manufactured and usedby or f"4 the VGr(ivc'ernment of the UnitedStates/fr g ernmental purposes without the payment tome of any royauy thereon 4in accordance fwithjthe provisions of lthe act of April v30, 1928 `(ch.' 460, 45 Stat. L. 467).
My invention relates to a' vfolding portable exhibiting device designed to `be inherently compact and light in 'weight including self-conf tained means for illuminating "changeable ex'- hibit panels, and particularly to bhwhich, when folded, forms its own case and may be trans-Y ported as a piece of hand luggage or shipped eliminates the use` of relatively heavy andcumbersomeshipp'ng crates, easelsand other e'xhiptsuppors l This device is particularly-'designedfor economical transportation by automobile thereby making relatively certain that an exhibit will accompany a motoring lecturer, teacher, professional man, salesman, or person engaged in an organizing or soliciting campaign, for illustrating lectures at a series of meetings in different places. Thereby, the inconvenience, inefliciency, and delay of shipping by express or other common carrier and of picking up and disbursing heavy crates at each stop is elimi- V nated. It is also designed so that the outside surfaces, when folded, are strong enough to withstand the normal damage of shipping; but
when open for exhibit, these scarred outside sur? faces will be hidden from view and the protected inside surfaces become the front of the exhibit.
In the accompanying drawingsv which illustrate a preferred form of my invention:
Figure l is a front elevation of my device, with two lateral frames in the plane of a central plane.
Figure 2 is a vertical section, on a larger scale, on the line 2-2 of Figure 4.
Figure 3 is a horizontal section, on the plane of section 3--3 of Fig. 1, of my device, the side frames being swung forwardly from the position of Figure 1 to make this device self supporting.
Figure 4 is a plan view of my closed device.
III indicates a main frame and II, I2 are lateral frames secured to the main frame I by identical piano-typeV hinges I3. The lateral frames Il, I2 are substantially half the width'of the frame I0. These frames are supported by a plurality of detachable legs I4 which are inserted through holes I5 in the frames I0, II and I2 into sockets I6 which are laterally attached within the frames. 'I'hese sockets are precisely located to give maximum support and at the same time, allow for diagonal insertion kof the exhibit panels I l, I8, I9 and to give maximum storage areabehind said panels.
`A double-end showcase electric socket20,221v
or 22 is attached within each of .the rframes IIJ.-
source inlet is necessary. A plugoutlet is provided at .the end ofthe continuous lighting circuit to permit operation of a slide projection machine, an electrical laboratory` device, any mechanical lvisual aid device or other apparatus with the exhibit. Glare shields 30, 3I, 32 cut off direct rays of light from the tubes 23 into the eyes of an observer.
Three reflecting light troughs are formed by the frames IIJ, Il, I2 and the glare shields 30, 3|,
32 and may be lined with aluminum foil or other suitable lining provided with a suitable reflecting surface (not shown) for reflecting light upon the exhibit panels.
Each of the frames I0,-II, and I2 is provided with a lower internal channel 33 and slightly inclined side channels 34V (see Figures l, 2) for holding exhibit panels. The center frame I0 holds a 30" x40" exhibit panel I'I, the size of a standard sheet of artists illustration board. The lateral frames II, I2 hold exhibit panels I8, I9, approximately one-half the width of the center panel, these three panels are of standard height. The insertion of the exhibit panels di vides each frame I0, II, I2. diagonally, `and creates a storage space behind each exhibit panel and an unobstructed exhibit surface on the front of each panel. The depth of the channels 33 and 34 makes possible the sliding of two extra exhibit panels into each frame for economic shipment and easy interchange of exhibits. The whole design is based on the standard 30 x 40 dimension to facilitate the use of the exhibiting device by amateur and inexperienced persons who find it necessary to exhibit, but cannot procure the services of professional exhibit personnel for construction of an exhibit support and shipping case and for cutting and fitting exhibit panels.
Backilaps 35, 36, 31 are secured to the frame Figure 4) the lateral frames ll and I2 are Cle-` tachably fastened to the main frame I0 by suitcase snap fasteners 42 while the back-flaps A3l] are similarly secured by similar fasteners 43.
The folded device may be carried by a suitable handle 44, a preferred positionof which is at the top of the side of the center frame or in back of the top of center panel where it Will be auto-A frame and arranged to support the exhibitor When set obliquely to the central frame and to fold against said central frame, each of said frames being provided with internally open inclined channels for interchangeably supporting standardizedfexhibit panels `,f.a back ap'-ion each frame providing a closure ffor temporary storage space Ain the rear of said exhibit panel channels vand a plurality of detachable supporting legs adapted for transportation insaid storage space. 2. A portable changeable exhibitor including a central exhibit `frame and two lateral exhibit 1 framesihin'g'edto opposite sides of said central matically hidden when the exhibit device is open. A canvas cover with commercial zipper closure and suitable canvas carrying handles may be used instead of handles attached on the exhibitor itself and for added protection.
The exhibit device may bemade of light Wood with metal hardware or all aluminum or of plastics or the like; In use, theside frames'would normally be unfoldedto make an angle with the main frame. Standing in this manner it lwould not be necessary to use a wall,` a booth, or any other supporting means except the supports provided in the -exhibit device.
It should be understood that the present dis- I closure is for the purpose'of illustration only, and that the invention includes all modifica! tions and equivalents which fall within the spirit and scope of the appended claims. WhatI claim is: 1. A portable changeable exhibitor including a centralv exhibit-v frame and two lateral exhibit frames hinged to opposite sides of saidy centralv frame'andYi-arranged to support the exhibitor `when set obliquelyto the central frame and to fold against opposite sides of said central frame, each'of :said frames being provided with internallyopenside channels inclined outwardly and vforwardlyfrom a lower internal supporting 20 channell whereby standardized exhibit panels are supported in a, position -for enhancing the effect of 'artificial illumination, a backii/lap closure on each frameprov'iding temporary; storagespace' and a p'rctectiondu'rnaship entfand 'StOraeG-Of" exhibit panelsjand ldetachable",supporting legs.
