INVENTOR. LAWRENCE C. HOWE ATTORNEYS DISPLAY DEVICE SUMMARY OF THE INVENTION The display device of this invention is designed particularly for outdoor use. It is a primary object of the invention to provide a display device adapted to illustrate posters or the like and having means for effectivey protecting the posters from the weather.

It is another object of this invention to provide a display device having a door closing the casing of the device, and improved means for preventing moisture from entering the joint between the door and the casmg.

Another object is to provide at least one and preferably two water-diverting channels for directing water away from the joint between the door and the casing of the display device.

Other objects and features of the invention will become apparent as the description proceeds, especially when taken in conjunction with the accompanying drawing, wherein:

FIG. 1 is a front elevational view of a display device embodying the features of my invention.

FIG. 2 is an end elevational view of the device shown in FIG. 1.

FIG. 3 is a fragmentary sectional view taken substantially on the line 3--3 in FIG. 1.

FIG. 4 is a fragmentary sectional view taken substantially on the line 4-4 in FIG. 1.

Referring now more particularly to the drawing, the display device forming the subject matter of this invention comprises a casing preferably formed of sheet metal and having a top member 12, a bottom member 14 and

end members

16 and 18 connected together end to end in the shape of a rectangle. The casing members 12-18 have near one side the inwardly extending

coplanar walls

20, 22, 24 and 26 which are connected together end to end in the form of a rectangle and define a front face 28 and a casing opening 30. The casing members 12-18 also have near the opposite-side of the casing the inwardly extending

coplanar walls

32, 34, 36 and 38 which are connected together end to end and define another front face 40 surrounding another casing opening 42. The

casing openings

30 and 42 of the casing are normally closed by

doors

44 and 46 which are identical in construction so that a description of one will be sufficient for both.

With the above in view, reference is made more in detail to FIGS. 3 and 4 of the drawings, wherein the door 46 is shown as comprising a panel 48 and a frame 50 around the marginal portions of the panel. The panel 48 may be formed of any suitable material but in the interests of simplicity of manufacture, it is shown as formed of a moldable plastic material. The frame 50 is preferably formed of sheet metal sections capable of being rolled or otherwise fashioned with relatively simple equipment. The frame 50 consists of the coplanar top, bottom and

end walls

52, 54, 56 and 58 which are disposed in a rectangle and define a rear face 60 which is parallel and opposed to the front face 40 of the easing in the closed position of the door. The door 46 is of a size sufficient to overlie and close the opening 42 of the casing.

The door 46 has the

frame members

62, 64, 66 and 68 which project rearwardly from the rear face of the frame 50 along the

walls

52, 54, 56 and 58 thereof. These frame members define a rectangle and extend at right angles to frame 50. The

frame members

62, 64, 66 and 68 have the laterally outwardly projecting flanges 72 which extend longitudinally of the frame members and connect end to end at the corners of the rectangle defined by the frame members. The flanges 72 are at the free or terminal edges of the frame members. In the closed position of the door, the flanges 72 close against the front face 40 of the casing along the four

walls

32, 34, 36 and 38 thereof to provide a continuous closed joint around the casing. Along these four walls there may if desired be provided a continuous sealing strip of rubber or like material to be engaged by the flanges 72 to provide a more perfect seal at the joint when the door is closed. However, a sealing strip has not been found to be necessary and ordinarily is omitted.

The

frame members

62, 64, 66 and 68 also have the laterally outwardly projecting flanges 74 which extend longitudinally of the frame members and connect end to end at the corners of the rectangle defined by the frame members. The flanges 74 are located between flanges 72 and the rear face 60 of the door. These

flanges

72 and 74 cooperate with the frame members and with the rear face of the door to define the

waterdiverting channels

76 and 78.

The front face 40 of the casing has the

frame members

80, 82, 84 and 86 projecting forwardly therefrom at right angles thereto. These frame members form a rectangle laterally outwardly of the

frame members

62, 64, 66 and 68 of the door to surround the latter frame members when the door is closed, terminating close to if not actually touching the rear face 60 of the door.

The door 46 is hinged to the casing by hinges 88 along the bottom connected to the lower edge of the casing and the lower edge of the door. The door 46 is normally held in closed position by a pair of quick releasing latches 90. When released by the latches, the door 46 is capable of swinging away to an open position.

As shown particularly in FIGS. 3 and 4, the central portion of the panel 48 is offset in an outward direction to provide a housing 92 having a transparent outer wall 94. The inner surface of the transparent wall 94 forms a mounting surface for a display poster 96 which may be readily inserted within thehousing in the open position of the door and held in place by suitable clips 97 carried by the door.

Housed within the casing midway between the

doors

44 and 46 are a plurality of electrically operated illuminating tubes 98. The purpose of the tubes is to illuminate the interior of the casing and permit the display posters 96 to be readily viewed through the transparent walls of the housing.

In use, and when the doors are closed, the posters 96 are supported against the outer walls 94 of door housings 92 outwardly of the joints between door flanges 72 and the front faces 28 and 40 of the casing as a safeguard against damage from moisture.

The overlapping

frame members

80, 82, 84 and 86 on the casing protect the joint at flanges 72 from the direct force of rain although they do not form a positive seal. Any water that may enter past the

outer frame members

80, 82, 84 and 86 is diverted away from the joint at flanges 72 first by the water-diverting channel 76 and thereafter as a further measure of protection by the second water-diverting channel 78. While the water-diverting channels extend around the four sides of the casing opening, the channels along the lower or bottom frame member 64 can be omitted without any appreciable loss in the ability of the channel construction to prevent water from contacting the sealed joint. It is important, however, that the water-diverting channels extend along the top frame member 62, and preferably also along the

end frame members

66 and 68 so as to direct the water to the bottom of the casing where it may be discharged through suitable openings 99 in the casing bottom frame member 82.

As noted above, the joint at flanges 72 of the doors which close against the

casing faces

28 and 40 does not have to provide a perfect seal. in fact, there will ordinarily be no entrance of moisture into the casing even if the flanges 72 do not quite touch the casing facing here and there. It has been found that substantially all moisture getting past

casing frame members

80, 82, 84 and 86 is diverted away from the joint by

channels

76 and 78.
