referring now to the drawings , the invention is illustrated in a first embodiment or constructional variation in fig1 - 4 , incorporated in a furniture piece in the form of a dining room buffet designated generally by reference numeral 10 . buffet 10 is supported on legs 12 and includes top , bottom and side walls 14 , 16 and 18 , respectively , a plurality of drawers 20 and hinged door 22 , the latter serving as a closure for compartment 24 , all of conventional construction . as seen in fig1 the rear wall of compartment 24 is provided by panel member 26 , although rear wall 28 of buffet 10 , as seen in fig3 is spaced from panel member 26 . lower groove 30 , having a width and thickness corresponding substantially to the width and thickness of panel member 26 , extends laterally across bottom wall 16 , parallel to and spaced forwardly of rear wall 28 . upper groove 32 , of the same width and thickness as groove 30 and spaced by the same distance from rear wall 28 , is provided in block 34 which is permanently secured within compartment 24 along the upper , rear side thereof . lower and upper blocks 36 and 38 , respectively , are secured to lower wall 16 and block 34 to extend between rear wall 28 and forwardly facing surfaces flush with lower and upper grooves 30 and 32 , respectively . leaf springs 40 are permanently anchored in groove 30 , as best seen in fig4 . the vertical length of panel member 26 is greater than the distance between opposing surfaces of wall 16 and block 34 , but less than the distance between the bottom of groove 30 and the opposing surface of block 34 . thus , the lower edge of panel member 26 may be placed within groove 30 , and downward pressure exerted on the panel member to compress springs 40 , permitting the upper edge of the panel member to be placed in alignment with groove 32 . upon release of the downward pressure , springs 40 will urge panel member 26 upwardly , engaging the upper edge thereof in groove 32 , as shown in fig3 . glue blocks 42 are affixed to the forwardly facing surface of panel member 26 , parallel to and spaced a short distance downwardly from the upper edge thereof . blocks 42 serve as handle means which may be manually grasped as panel member 26 is placed in grooves 30 and 32 as described above , as well as to apply downward pressure to the panel member to remove the upper edge from groove 32 and permit removal of the panel member from compartment 24 . when panel member 26 is positioned with its lower and upper edges in grooves 30 and 32 , respectively , it is urged upwardly so that glue blocks 42 abut against block 34 , and the spaced relationship of panel member 26 and rear wall 28 provide hidden compartment 44 rearwardly of compartment 24 . when viewing the interior of compartment 24 , panel member 26 appears to be a permanently installed rear wall , glue blocks 44 appearing to be of the type conventionally provided to fixedly secure panel 26 and block 34 . thus , to anyone unaware of the removability of panel member 26 , the presence of hidden compartment 44 is essentially undiscernable . turning now to the construction of fig5 - 8 , the invention is illustrated in conjunction with upper portions of a piece of furniture such as a desk or secretary , denoted by reference numeral 46 . included in the upper structure of furniture piece 46 is a compartment divided into uppper and lower portions 48 and 50 , respectively , by removable shelf 52 . door 54 provides a hinged front closure for both the upper and lower portions of the compartment . shelf 52 is supported upon , but not attached to , support members 56 , 58 and 60 , fixedly attached to side walls 62 and 64 and panel member 66 , respectively . as seen in fig8 grooves 68 and 70 are formed in side walls 62 and 64 , respectively , and extend between lower and upper walls 72 and 74 , respectively . leaf springs 76 and 78 are fixedly attached at their mid - points to blocks 80 and 82 which , in turn , are glued or otherwise affixed to side walls 62 and 64 and / or rear wall 84 . the width of panel member 66 is greater than the distance between side walls 72 and 74 , but less than the distance between the bottoms of grooves 68 and 70 . thus , one of the vertical , side edges of panel member 66 may be placed in one of grooves 68 and 70 , an inward or rearward force exerted on the panel to deflect springs 76 and 78 , and the panel moved laterally to engage the other edge in the other groove . panel member 66 will be biased by springs 76 and 78 into firm engagement with the frontward surfaces of grooves 68 and 70 . shaft 52 may then be placed on support members 56 , 58 and 60 , as shown in fig5 . placement of panel member 66 as described above provides a secret or hidden compartment 86 between the actual rear wall 84 of the furniture piece , and removable panel member 66 . to one observing the interior of the compartment behind door 54 , panel member 66 appears to be a permanently installed , fixed wall . support member 60 , while providing handle means for insertion and removal of panel member 66 , appears to be a normal support for the removable shelf . in fig9 is shown the lower portion of a furniture piece in the form of a standing buffet or highboy 88 having an upper section with doors and / or drawers , one of which is denoted by reference numeral 90 , and a lower section having doors and / or drawers 92 . between the upper and lower sections , extending the full width of buffet 88 , is opening 94 for a sliding drawer which has been removed and is not shown in the drawing . decorative moulding 96 is positioned between the upper section and the central drawer space on the front and sides of the buffet . panel member 98 , having flat strips 100 and 101 affixed to and extending outwardly from the side edges thereof , is shown in fig9 extending partially into central drawer opening 94 , as it would appear when being placed in or removed from a position within buffet 88 , as explained below . panel member 98 is shown from both its upper and lower sides in fig1 and 11 , where it will be noted that strips 100 and 101 do not extend the full length of the side edges and panel member 98 . as seen in fig1 , block 102 extends across the back of the buffet 88 , between bottom wall 104 of the upper section of the furniture piece and rear wall 106 of central drawer space 94 . front and rear dust panel supports 108 and 110 , respectively , are affixed to lower surfaces of moulding 96 and block 102 , and each extend the full width of buffet 88 . opposing surfaces of supports 108 and 110 are provided with grooves 112 and 114 , respectively , in central portions thereof . leaf springs 116 are each affixed at one end within groove 114 , as shown in fig1 . the front - to - rear length of panel member 98 is greater than the distance between opposing surfaces of panel supports 108 and 110 , but less than the distance between the bottoms of grooves 112 and 114 . thus , panel member 98 may be inserted into drawer space 94 , as shown in fig9 and the rear , lateral edge placed in groove 114 . a rearward force is applied to the panel member , using strips 100 and 101 as handle means , compressing springs 116 to premit insertion of the forward , lateral edge of panel member 98 in groove 112 . the forward bias of springs 116 urges strips 100 and 101 into abutment with support 108 . in this position , panel member 98 appears to be a permanently installed dust panel , just as fixed panel members 118 and 119 on each side thereof . strips 100 and 101 , although actually providing handle means for insertion and removal of panel member 98 , appears to be fixed to panel members 118 and 119 , as well as to panel member 89 to cover the adjacent edges of the dust panels , as would normally be done in high quality furniture construction . thus , the presence of and means of access to compartment 20 are essentially undiscernable to those unaware of its existence . turning now to fig1 - 18 , a furniture piece in the form of a bedroom dresser 122 is shown . dresser 122 includes a plurality of slidable and removable drawers 124 , one of which has been removed from the space 126 which it normally occupies . dust panels and both side and center drawer guides are provided within each drawer space , in accordance with conventional constructions of such furniture . panel member 128 and side and center drawer guides 130 and 132 , respectively , are shown within drawer space 126 . although the dust panels within the other drawer spaces are fixed , panel member 128 is removable to provide access to an otherwise hidden compartment , as explained below . front and rear support members 134 and 136 , respectively , extend laterally across the front and rear sides of the dresser 122 , and opposing surfaces thereof are provided with grooves 138 and 140 , respectively , as shown in fig1 . leaf springs 142 are affixed within groove 140 , as best seen in fig1 . as in the previously described embodiments , panel member 128 has a length permitting insertion of the forward and rear lateral edges thereof in grooves 138 and 140 , with springs 142 exerting a forward bias . center drawer guide 132 is notched at each end , as are the other center drawer guides , to extend over support members 134 and 136 . all center drawer guides other than 132 are affixed to the corresponding support members by wood screws extending through the overlaying portions at each end of the center guides . accordingly , screw heads 133 , as seen in fig1 and 18 , are glued in openings in guide 132 to add to the illusion that panel 128 is permanently installed . lower wall 144 is fixedly positioned in parallel , spaced relation to panel member 128 , as seen in fig1 and 17 , providing hidden compartment 146 . from the foregoing , it is apparent that the objects of the invention are effectively achieved by each of the several described constructions , variations of which within the scope of the invention will also be apparent . in each case , a removable panel member covers one side of a compartment wherein relatively small articles may be concealed , thereby decreasing the possibility of their being stolen .
