Abstract:
The assembly has an interior enclosure formed by a back frame having a U-shaped curl at each outer edge of its top and bottom sides. A four sided hinged cover engages flush with the bottom of each U-shaped curl to prevent water access to the interior of the assembly. A display is presented on a tack board mounted in the interior of the enclosure along with a pocket panel to enclose miscellaneous papers.

DESCRIPTION 
     PRIOR APPLICATION 
     This application is a continuation-in-part of my earlier U.S. patent application Ser. No. 920,532, filed Oct. 20, 1986, now abandoned. 
    
    
     TECHNICAL FIELD 
     This invention relates to a display device. More specifically, it refers to a self-contained weatherproof inspection board enclosure for use at construction sites. 
     BACKGROUND ART 
     Display devices for printed material such as shown in U.S. Pat. No. 3,874,103 employ magnetic devices to maintain visual material within the display area and a bubble member to protect the visual material from inclement weather conditions. Another sign element containing magnetic devices is described in U.S. Pat. No. 3,367,049. Neither of these references describe devices that can be conveniently used as a construction site inspection board since they do not combine features of strength and low cost with proper components useful to the construction trade. 
     SUMMARY OF THE INVENTION 
     I have solved this problem by creating a weather resistant construction site inspection board that is durable, low cost and structurally designed to provide all the component parts necessary for the construction industry. 
     My assembly employs a back frame enclosure with a U-shaped curl at each exposed edge. A tack board is mounted within the enclosure for displaying or holding construction documents such as notice of commencement, licenses and construction blueprints. A pocket plate is attached to the bottom of the back frame on its exterior edges to form a pocket. A four sided, hinged cover latches to the U-shaped curl at the bottom of the back frame and presses against the bottom surface of each U-shaped curl.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring now to the drawings in which like reference characters designate like or corresponding parts throughout the several views, there is shown in FIG. 1 the weatherized construction site inspection board assembly 10 having a back frame 12 and a four sided cover 14 hinged through grommet 66 in an upper side surface 18 of the back frame 12 and latched by latch 16 to the back frame 12. 
     The enclosure 20 of the back frame 12 is used to mount a tack board 22 by glue to a back panel 24 which is integral with the side panels 18 of the back frame 12. The back frame 12 is made from a plastic material such as high molecular weight polyethylene or fiberglass. The tack board is made from cork, homasote or polystyrene. 
     Also integral with the side panels 18 and back panel 24 is top panel 26 and bottom panel 28. Bottom panel 28 has a groove 30 formed between a pair of nipples 32 and 34 on its interior surface 36. A mounting rod 38 joins each side panel 18. A pocket plate 40 fits into groove 30 at a lower end and snaps onto shaft 38 with a pair of integral fingers 42 and 44 at its upper end. The pocket plate 40 forms a pocket 46 for receiving and retaining construction documents. 
     The back frame 12 can vary in size, but for use on most construction jobs the frame 12 will be twenty-seven inches wide, twenty inches high and three inches in depth. 
     As seen in FIG. 3, the exterior edge of top panel 26 has a u-shaped curl 48. In like manner bottom panel 28 has a U-shaped curl 50. Side panels 18 (FIG. 4) each have a U-shaped curl 52 at their exterior edges. 
     Covering the enclosure 20 against rain is a four sided front cover 14. The cover has integral side panels 54 at each side and an integral top panel 56 which has a curl 58 furthest from the cover face 60, which acts to cover a portion of the top of top panel 26. 
     A hinge is formed on both sides 18 of the back frame 12 and the side panels 54 of the cover 14 by pushing a push pin 64 through grommet 66 located at the top of front cover 12 as seen in FIG. 8. At the top of side panels 18 is another corresponding grommet 66 receiving push pin 64. A mounting extension 62 at the top of side panel 18 is a hinge mount for the cover 16. 
     The bottom of cover 14 has an inward curl 68 ending in a latch tab 16 frictionally engaging the end of the U-shaped curl 50 on bottom panel 28. 
     Each of the U-shaped curls on the exterior edges of the back frame give slightly as the front cover 14 is pushed against them and latched to the bottom panel 28 by latch tab 16. The cover 14 fits flush and snugly against the bottom of each U-shaped curl on the back frame 12. This tight fit prevents even wind-driven water from entering the enclosure 20. 
     Mounting means such as holes 70 and 72 are provided to attach the assembly to a post or other available device in the area of the construction site. 
     In an alternate embodiment the tack board 22A can be reduced in size to provide room for a blue print chamber 74. This chamber has a cover 76 hinged 78 near the top so the cover 76 can be used to hold front cover 14 open. This is accomplished by inserting the end 80 of the cover 76 into curl 68 when cover 12 is open. A second pocket plate 82 can be hung behind plate 40. 
     An alternate inspection board assembly 10a is shown in FIG. 10-12. The assembly 10a has a four side cover 14a which hinges at a top extension 62a from side panel 18a of the back frame 12a. 
     The back frame 12a contains an enclosure 20a with back panel 24a supporting a tack board 22b. The side panels 18a, the back panel 24a, top panel 26a and bottom panel 28a are all integral components to form the enclosure 20a within the back frame 12a. 
     The top panel 26a has an outwardly extending curl 48a and the side panels 18a have an outwardly extending curl 52a. The back panel 24a has several ribs 84 for added strength. 
     A pocket plate 40a is mounted substantially perpendicular to the bottom panel 28a along its exterior edge and along the bottom exterior edges of the two side panels 18a. The pocket plate 40a forms a pocket 46a for use in retaining loose documents. 
     The cover 14a has integral components including side panels 54a, top panel 56a, cover face 60a and bottom panel 86. Bottom panel 86 also has an optional latch plate 16a. The cover 14a is held in place by push pin 64a. The front surface of cover face 60a can be used to display the name of the user of the assembly. A 2×4 post will fit easily between ribs 84 so that the assembly can be screwed or nailed flat to the upright post for ease of display. 
     Minor modifications and equivalent elements can be substituted in the construction board assembly without departing from the invention as described herein.
