referring to the drawings in detail wherein like elements are indicated by like numerals , there is shown a delivery container 1 with a signaling system 30 constructed according to the principles of the present invention . the delivery container 1 will generally be a mailbox type ( see fig1 a , 3 , 5 - 6c ) or a newspaper type ( see fig2 b and 4 ), although other types may be constructed according to the principles of this invention . the delivery container is comprised of a hollow , elongated housing 2 , having an open front end 3 , a closed back end 4 , a bottom 5 , opposite side walls 6 attached to said bottom 5 , and a top 7 extending from one side wall 6 to the opposite side wall 6 . the front end 3 , back end 4 , bottom 5 , side walls 6 and top 7 define a housing interior 1 . the container housing interior 11 has a generally horizontal , longitudinal , central axis . an elongated slot 18 is formed centrally in the delivery container housing bottom 5 , said slot 18 running parallel to the container housing interior horizontal , longitudinal , central axis . the slot 18 begins near to the housing front end 3 and extends nearly to the housing back end 4 . a closure member or door 8 may be mounted on the housing front end 3 adjacent a front bottom edge 9 for pivotal movement around an axis 10 between an upright position closing the container housing 2 and a down position opening the container housing 2 and providing access to the container housing interior 11 through the housing front open end 3 . the closure member 8 includes a handle 12 to facilitate opening and closing the container housing 2 , and an extension 13 on the housing top 7 at the housing front 3 to help retain the door 8 in its closed position . a mechanical flag 19 may also be rotatably attached to the housing side wall 6 . the container 1 is further comprised of a base 20 having a generally rectangular shape . the base 20 includes a bottom wall 21 , a front side wall 22 , a back side wall 23 , and lateral side walls 24 and 25 . the walls of the base 20 are transparent and define an internal chamber 26 which is open at the top , but which is adapted to be covered by the container housing bottom 5 when the housing 1 is mounted to the base 20 . the length of the base 20 is such that the container housing front end 3 extends slightly beyond the base front side wall 22 . the base 20 extends rearwardly past the container housing bottom 5 and upwardly past the container housing back end 4 so that the base back side wall 23 is positioned near to or above the container housing top 7 . the base bottom wall 21 is curved as it extends rearwardly past the container housing bottom 5 and upwardly past the container housing back end 4 , said curved portion being designated with the reference numeral 27 . the side 6 and back 4 walls of rural - type mailboxes usually extend slightly below the mailbox bottom 5 and define a downwardly extending skirt 14 therearound . the container 1 may be attached to a post 17 with fasteners 15 inserted through skirt openings 16 into the post 17 . the base 20 is sized to be received within the skirt 4 and the container 1 is mounted on the post 17 by extending fasteners 15 through openings 16 in the skirt 14 and the base 20 . the delivery container 1 of the present invention contains a signaling system 30 . the signaling system 30 has a deployed position and an undeployed position . the signaling system 30 is comprised of a push plate assembly 31 positioned in the container housing interior ii and a signal element 40 positioned within the base internal chamber 26 . the push plate assembly 31 is connected to the signal element 40 by means of a connector 50 . the push plate assembly 31 is located within the housing interior 11 and is comprised of a generally flat , thin , upright plate 32 with a forward support plate 33 and a rearward support plate 34 bracing the upright plate 32 in a vertical plane transverse to the housing interior , horizontal , longitudinal , central axis . the upright plate 32 lies in a plane parallel to the closed door 8 and back end 4 . the upright plate 32 is generally rectangular , extending nearly to the housing side walls 6 , the housing top 7 and bottom 5 . the upright plate 32 has a front face 35 facing the housing front end 3 and a rear face 36 facing the housing closed back end 4 . the forward support plate 33 is attached to the upright plate front face 35 and the rearward support plate 34 is attached to the upright plate rear face 36 . both support plates 33 , 34 generally have less than 60 % of the height of the upright plate 32 and are positioned so that their bottom edges are coincident with the bottom edge 37 of the upright plate 32 . the push plate assembly 31 may have a finger hole 38 formed centrally through the forward support plate 33 , upright plate 32 and rearward support plate 34 . alternatively , a knob could be attached centrally to the forward support plate 33 . the finger hole 38 or knob provide a means for moving the push plate assembly 31 forward toward the housing front end 3 . the upright plate front face 35 may be colored or patterned and may have instructions imprinted thereon , such as the word &# 34 ; push &# 34 ; 39 . a stop element 55 may be installed near to the housing back end 4 to halt the rearward movement of the push plate assembly 31 . a connector 50 is attached to the push plate assembly rearward support plate 34 . the connector 50 has a block like portion 51 attached to the push plate assembly rearward support plate 33 and a central , downwardly projecting , holding element 52 extending through the housing bottom slot 18 into the container base internal chamber 26 . the downwardly projecting , holding element 52 attaches to the signaling system signal element 40 contained within the base internal chamber 26 . the signal element 40 is comprised of a thin , flat , flexible signal plate 41 having a distal end 42 and a proximal end 43 . in the signal system 30 undeployed mode , the signal plate 41 lies in a plane parallel to the housing bottom 5 and base bottom wall the signal plate proximal end 43 terminates in a support element 44 with a central aperture 45 formed therein . the connector downwardly projecting , holding element 52 extends through said support element central aperture 45 . the holding element 52 terminates in a crosspiece 53 thereby holding the support element 44 firmly attached to said connector 50 . the signal plate 41 may be colored or patterned with any desired indicia 46 . in operation , the door 8 on the delivery container housing 2 is opened and delivered materials are inserted into the delivery container housing interior 11 , thereby deploying the signaling system 30 . the signaling system 30 is deployed by forcing the signaling system push plate assembly 31 rearward toward the housing back end 4 . the rearward movement of the push plate assembly 31 translates a rearward movement within the base internal chamber 26 to the signal element 40 via the connector 50 . as a consequence , the signal plate distal end 42 is forced toward the base back side wall 23 . the signal plate 41 flexibility and the base bottom wall curve 27 permit the signal plate distal end 42 to smoothly move backward and then upward toward the base back side wall 23 . the signal plate pattern 46 becomes visible through the transparent base 20 to an onlooker thereby signaling that a delivery has been made . when the delivered materials are removed from the delivery container housing interior 11 , the signaling system 30 may be undeployed by pulling the push plate assembly 31 toward the housing front end 3 by means of the finger hole 38 or knob attached thereto . it is understood that the above - described embodiment is merely illustrative of the application . other embodiments may be readily devised by those skilled in the art which will embody the principles of the invention and fall within the spirit and scope thereof .
a delivery container with a signaling system to indicate delivery of materials . the delivery container signaling system is comprised of a push mechanism within the container attached to a signal plate within a transparent base extending across the bottom of the delivery container and upward over the rear of the delivery container . the movement of the push mechanism rearward within the delivery container causes the enclosed signal plate rearward and upward across the container rear when delivered materials are pushed into the container against the push mechanism .
