Patented Apr. 29, 1930 UNITED stares MARIfrs ANDERSEN' BRAASTAD, or OSLO, NORWAY EXHIBITION AND ADVERTISEMENT STAND Application filed October 3 1927, Serial ITO. 223,815, and in fiorway August 18, 192*). l

The present invention relates toexhibiti'on and advertisement-stands adapted to be placed at parks, squ fes and the like.

The main o-bject of the invention is to provide a stand substantially built up of glass and arranged in such a manner that the,

framework carrying the glas fields will'not become visible. A further object is to provide heating devices for the stand which devices during the 'Winter prevent accumulation of ice and snow that otherwise would disfigure the stand. p p

The invention is by way of example illustrated on the accompanying drawings in which: 7 I I p j Fig. 1 is an elevation View, with the left half in section, of a stand embodying the invention. p Y

Fig. 4: is a plan view of one of the glass fields in the roof.

Fig. 5 is a vertical section of the lower part of the stand Withan underlying room, and K 1 Fig. 6 is a plan view ofthe same. I

l/Vhile the invention hereinafter \vill be' de-- scribed and illustrated in connection with an hexagonal stand it should bealnderstood that the cross-section and the shape otherwise of the stand maybe any one without departing from the scope of the invention.

' Referring to thedrawihg's 1 denotesfthe base of the stand which is walled and roofed with glass- fields 2 and 3 respectively. Arranged at a somewhat lower levelv than the roof proper are the eaves also composed of glass-fields 4:. All the fields are, as above mentioned, made of glass and are'retained in their respective positions by means of a suitable framework. Said framework may be built up of bars or the like of suitable cross-sections such as round metal rods 5 (Fig. having longitudinally extending grooves 6 for receiving the edge portions of the glass fields. Between the walls of the channels 6 and the fields edges is placed an intermediate layer or lining 7 of rubber or the like. 'Furtherthe' rods 5 are provided with longitudinal bores 8 for electric carrent'conductin'g wires. j In order tomake the supporting framework invisible the outer and inner sides the'reof are coveredbyan illuminating device such as shown in Fig.3. The outer and inner sides of the rod 5 are'fcovere'd by glass tubes '9 and 10 respectively, the r'ears' of which are shaped to :fit to the periphery of the'r'od. Said tubes 9 10 may be mercury vapour lamps or the like/thus acting as illuminating means for the stand andcoincidently concealing'the frameworkthereof, In order that the tubes I or lamps even in d'ay-light, When they are extingiiished, shall serve the object aimed at, the outer tubes 9 are given an opaque ground or frosted surface in such a manner that they will be more or less invisibl from the exte- 'rior of the stand. r Between the roof and the eTaves an'c-lat the base of the standare arranged pellucid fields 11 and 12 respeetively for placing bills or advertisements thereon. Said fields may be mounted replaceably in a manner known per se,' either from the outside orthe intenor of the stand. Behind the fields 11, 12

are placed suitable illuminating device's l3 and 14 respectively; wherebyalso these fields are illuminated.

Under the eavesare further placed piellucid fields 15 for bills and also these fields are pro vided With illuminating devices at the rear thereof. In order to prevent that the light radiating fromthese fields shall interfere with the effect offthe light from the stand proper said fieldsare pl'a'ced somewhat higher than the lower edge of the eaves and preferably sloping u wards as illustrated at the left part of Fig. 1.

' To preventaecumulation of ice and snow on the roof surfaces 354 suitable heating devices aremou'nted within or under sai'dfie'lds. I I

These heating devices preferablymay consistof resistance wires einbeddedin channels or grooves 16; in the fields 3-, 4 (Fig. 4) ,whieh Wires in the cold season, si'ipplied'with .eleotric current; serve as heaters. Instead of being embedded iii Eliafi'fils', the resistance "wires and in close approximation thereto.

By adapting the colour and lighting of the roofand bill-fields to the remaining light-.

ing of the stand an even effect of light is obtained and no dark portions will appear owing to the framework and the roof.

The electric light for illumination may be switched on and off manually, or automatically by means of a clock-drive, a light sensitive cell or the like;

One of the fields 2 may be provided at one side thereof with hinges'to serve asa door which gives access to the interior of thestand.

The stand described above is mainly intended to be used for usual exhibition of goods and advertisement thereof, but may also be .used for mannequin exhibition. In such case a chamber fonchanging10f costumes may be arranged below the proper stand, as indicated in Figs. 5 and 6.

1 is the base of the stand and 17 the floor thereof. Below the floor is provided a chamber 18 having an entrance and exit 19 normally closed by a plate or door 20... Access from the chamber 18 to the stand proper may be had by means of a staircase or a lift means. An embodiment of such a lift arrangement is illustrated in Figs. 5 and 6. The central portion 21 of the floor 17 is connectedto a means for lowering the same into the chamber 18 andraising the same to nor- 1 mal position. In Fig.5 the'said portion 21 is secured to the end of a vertical threaded rod 22 which meshes with a rotatable nut 23 adapted to be rotated, but not raised or lowered, either manually or by a suitable motor The central floor portion 21.

(not shown). is guided between guides 24 when raised or lowered. j j

In order to conceal the opening in the floor 17 when the central portion 21 is lowered the following arrangement maybe used. In the stand are arranged a set of vertical guiding threads 25 placed near the periphery .ot the said opening.

I At the floor is'p'laced a piece of'suitabl'e cloth 26 to which aresecured guiding rings or the like'cooperating with the said guiding threads, and strings by means of which" the cloth may be drawn upwardly along the guiding threads toform a curtain whichconceals the opening in the floor. In

"lowered position,"resting on thefioor 17, the

said clothor curtain will'conceal the joint between the central portion 21 and the remainderof the floor 17. The guiding threads and the stringsmay consist of gut or the like, whereby they are practically invisible.

It will beun derstood that'the details of the stand maybe altered in many ways with out departing from the spirit of the invention, and the special embodiment here illuscertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is: H

1. An exhibition-stand comprisinga framework forming a housing and a roof and built up of glass panels, a chamber below the housing, a floor separating the interior of the housing from the chamber, and means whereby a portion of the floor is adapted to be low ered into said lower chamber and again raised 7 to normal position.

ber, adjustable supporting means in the casing'fOr raising and lowering the disc portion and for holding the same in normal position flushed with the main part of the floor, and guiding means between the floor and the bot tom of the chamber for the disc-like portion.

3. An eXhibition-standin accordance with claim 1, wherein vertical guiding threads arearranged in the upper part of the housing and anchored to the floor adjacent the movable portion thereof, and a cloth engaged with the guiding threads and serving as a cover to hide the movable portion of the floor. r v 4. AneXhibition-stand in accordance with claim 1, wherein the framework includes vertically arranged rods for accommodating the 'faces of the rods and the tubes on the outer sides of the rods having a frosted outer surface, substantially as and for the purposes set forth. w 1

In testimony whereof'l'atfix my signature.
