a display rack 10 in accordance with the present invention is shown in fig1 to include two component supports 12 and it will be appreciated with the description following that any number of component supports could be incorporated into the display rack . when assembled as shown in fig1 , the two component supports define a completed rack with two display shelves 14 for inanimate objects 16 such as golf balls . the display rack shown in fig1 has an uppermost support component 12 u and a bottommost support component 12 b even though as seen in fig2 , for example , an intermediate support component 12 i could be positioned between the uppermost and bottommost components to add a third display shelf 14 . referencing fig3 , the three component supports 12 shown in fig2 are separated . the intermediate support component 12 i can be seen to include a plate - like back 18 that has a horizontal groove 20 routed or otherwise formed in a front face thereof near the bottom edge of the back plate . a relatively thin display shelf 14 has its rear most edge inserted into the groove and is retained therein either frictionally , with adhesive or with other suitable means . the shelf itself is provided with a plurality of indentations 22 formed in a top surface thereof at equally spaced locations with the indentations being provided to releasably retain inanimate objects 16 to be displayed in the rack at the predetermined locations . for example , in the embodiment shown in fig1 - 6 , the indentations 22 form a segment of a sphere so that a golf ball or other spherical object could be placed or seated in an indentation to keep the ball from rolling off the shelf . immediately below the shelf 14 on the front face of the support component 12 , a tongue - and - groove connector 24 is formed so that a forwardly projecting tongue 26 is defined by a rearwardly projecting groove 28 immediately thereabove and a lower edge 30 of the back plate 18 . the tongue and the groove are defined by substantially horizontal surfaces 32 and substantially vertical surfaces 34 but as is probably best appreciated by reference to fig4 , the substantially horizontal surfaces are in reality sloped slightly downwardly and rearwardly from the front face of the back plate toward the rear of the back plate . the substantially vertical surfaces are similarly slightly inclined upwardly and rearwardly from the front face of the back plate toward the rear face . it will therefore be appreciated a front lip 36 is defined at the upper front edge of the tongue 26 and an inner corner 38 in the bottom rear edge of the groove 28 . the lip is positioned higher than the inner corner for a reason to be explained hereafter . a similar tongue - and groove connection 24 is formed near the top edge of the back plate in its rear surface so that the tongue 26 overlies the groove 28 but again the substantially horizontal surfaces 32 are inclined slightly rearwardly and downwardly while the substantially vertical surfaces 34 are inclined slightly rearwardly and upwardly identically to those in the front face of the back plate . the tongue - and - groove connection in the top of the back plate is therefore complimentary to the tongue - and - groove connection in the bottom of the back plate so that , while not illustrated , the tongue - and - groove at the top of one intermediate support component 12 i can be received in the tongue - and - groove connection of a next adjacent upper identical intermediate support component 12 i such that the back plates of both intermediate support components are co - planer . as will be appreciated , any number of intermediate support components can therefore be interconnected and suspended from each other with the rearwardly and downwardly inclined surfaces in the tongue and the groove of each connector encouraging a positive interconnection by gravity . further , if one were to try to horizontally remove an intermediate component from an interconnected intermediate component , it could not be easily separated unless the lowermost component was pulled upwardly and forwardly which is restricted by the display shelves 14 . this is due to the fact that the above - defined lip of the tongue 26 is higher than the inner corner of the groove 28 . if the support components are made of a soft wood or plastic they can be snapped together or apart but typically the support components are interconnected or supported by sliding one component longitudinally of the other . looking again at fig3 , an uppermost component 12 h of the display rack 10 is shown to be very similar to an intermediate component 12 i in that it has a lower tongue - and - groove connector 24 along the lower edge of the back plate 18 and in the front face thereof and the connector is immediately beneath a shelf 14 mounted on the back plate as described above with the shelf having a plurality of indentations 22 . the top edge of the back plate in the uppermost support component , however , does not include a tongue - and - groove connector as in the intermediate components . a horizontal overhang plate or flange 40 , however is secured to the top edge of the back plate of the uppermost component along its rear edge for decorative purposes so that the overhang plate or flange 40 overlies the shelf 14 on the uppermost support component of the display rack . similarly , the bottommost component 12 b of the display rack 10 has a tongue - and - groove connector 24 formed along its top edge in the rear face thereof but no tongue - and - groove connector along the bottom edge . a bottom wall or flange 42 of the bottommost support component , however , is connected to the bottom edge of the back plate 18 of the bottommost component so that the bottom wall or flange projects forwardly and horizontally from the lower edge of the back plate . rather than having a shelf in the bottommost component , the bottom wall or flange 42 serves as a shelf in the display rack and has a plurality of aligned indentations 22 formed therein . it will be appreciated from the above that the display rack 10 will preferably include an uppermost support component 12 u , a bottommost support component 12 b and one or more intermediate support components 12 i that are interconnected with each other and / or to an uppermost support component or a bottommost component depending upon the number of components desired for the display rack . as mentioned above , the tongue - and - groove connectors 24 on the support components cooperate with each other in supporting and interconnecting the support components so they can best be separated by sliding one component longitudinally of the other . it will also be appreciated that any number of intermediate support components 12 i can be provided as by adding or subtracting from an existing display rack . further , as shown in fig1 , there does not need to be an intermediate support component , but rather the bottommost component 12 b can be connected directly to the uppermost component 12 u if a two - shelf display rack were desired . as will be appreciated , a display rack 10 with multiple components is vertically suspendable from a vertical surface such as a wall . when suspending the display rack from a vertical support surface , one or more notches 44 ( fig6 ) could be formed in the rear of the uppermost component 12 u to receive a nail or other fastener projecting from the vertical support surface . if the recess was of the type illustrated in fig6 where it included a relatively large circular opening 46 near its bottom to receive the head of , for example , a screw and a relatively thin neck 48 projecting upwardly therefrom smaller than the head of the screw , a very positive interconnection of the display rack with the vertical support surface can be obtained . while the embodiment shown in fig1 - 6 illustrates one form and use of the display rack in accordance with the present invention , the systems incorporated into the display rack for releasably but positively positioning objects being displayed could be varied . for example , in fig7 , the uppermost component 12 u of the display rack 10 , which is shown as being taller than the intermediate 12 i and bottommost 12 b components , also includes a plurality of horizontally disposed cylindrical pins 50 projecting forwardly from the back plate 18 on which objects such as spools of thread , or the like could be displayed . also , on the top surface of the shelf 14 of the uppermost component , a pair of rectangular embossments or raised areas 52 are provided which might cooperate , for example , with a recess in the bottom of a figurine that might be displayed on the shelf . on the shelf of the intermediate component 12 i , a plurality of holes 54 are formed through the shelf through which other inanimate objects such as might have a larger upper body than a lower body might be positioned so that the lower body could be dropped through the hole but the larger upper body would be supported above the shelf . on the bottom wall 42 of the bottommost support component 12 b , a plurality of upstanding pins 56 are provided which again , for example , might be used to support spools of thread , yarn or the like or other similar objects for display . it will be appreciated from the above , that while several embodiments of the invention have been illustrated , it will be evident to those skilled in the art that other variations could be made to the shelves , the bottom wall , or the back plates for displaying objects of different configurations and the invention is not intended to be limited to those few possibilities illustrated . further , while one particular tongue - and - groove system for interconnecting adjacent support components has been illustrated and has been felt to work very well , other systems might also work for interconnecting the support components in co - planer relationship in any manner so that they are not easily separated . although the present invention has been described with a certain degree of particularity , it is understood the disclosure has been made by way of example , and changes in detail or structure may be made without departing from the spirit of the invention as defined in the appended claims .
a display rack for displaying a plurality of inanimate objects that may take different shapes and sizes includes a plurality of interconnected support components each of which has a system for displaying such objects . the support components are releasably interconnected to increase or decrease the size of the display rack by adding or subtracting support components . in this manner , the display rack is adjustable to accommodate a collection of objects for display of any desired size .
