with reference to fig1 , a casket 10 is shown incorporating the corner attachment mechanism 12 of the present invention . the casket has a top 14 , a pair of oppositely disposed end walls 16 and two oppositely disposed side walls 18 . advantageously , the casket 10 may be made from wood , although the corner attachment mechanism 12 is not limited to use on wooden caskets , i . e ., the corner attachment mechanism 12 has equal applicability to metal caskets . with further reference to fig2 , end walls 16 and side walls 18 are joined by brace or mounting member 20 . brace 20 includes throughhole 22 which , as described below , is sometimes used to mount corner attachment mechanism 12 to the casket 10 . the ends of end wall 16 and side wall 18 do not meet such that an opening 24 is formed which provides access to the interior of the casket 10 . corner attachment mechanism 12 includes a back plate 30 , an attachment clip 32 , and an ornamental corner insert 34 . the back plate 30 includes end pieces 36 , 38 joined by vertical member 40 . vertical member 40 includes an elongated groove 42 with a throughhole 44 extending from the front side of the vertical member 40 to the back side of vertical member 40 . vertical member 40 is secured to brace 20 by fasteners 45 . fasteners 45 could be screws , nails , brads and the like , but are preferably screws . vertical member 40 is preferably wood but could be made from any suitable structural material such as steel , aluminum , plastic or the like . with reference to fig2 - 5 , attachment clip 32 is sized to rest within and conform to the elongated groove 42 . attachment clip 32 is removably affixed to vertical member 40 with fasteners 46 inserted through throughholes 48 in attachment clip 32 . fasteners 46 are preferably screws . attachment clip 32 includes an indexing member 49 ( fig4 ) with throughhole 50 which aligns with and penetrates throughhole 44 when attachment clip 32 is placed into elongated grove 42 . indexing member 49 is positioned closer to the upper end of attachment clip 32 than the lower end . as a result of the offset position of indexing member 49 , the attachment clip 32 can be inserted into elongated groove 42 in only one orientation . as such , the installation and removal of the ornamental corner insert 34 will be consistent for all caskets 10 . that is , the ornamental corner insert 34 will always be installed by sliding it from left to right and removed by sliding it from right to left . with specific reference to fig4 and 5 , attachment clip 32 further includes two keyhole grooves 52 , 54 . keyhole grooves 52 , 54 include , respectively , openings 56 , 58 and slots 60 , 62 . slots 60 , 62 are partly formed by oppositely disposed rib members 64 , 66 . each rib member 64 , 66 includes a protrusion 68 , 70 . as will be explained in greater detail below , protrusions 68 , 70 assist in attaching ornamental corner insert 34 to the attachment clip 32 . ornamental corner insert 34 includes a decorative or ornamental side 80 and a mounting side 82 . generally , the decorative side 80 can be of any aesthetically pleasing shape . mounting side 82 , however , is preferably , but not necessarily , flat so that the ornamental corner insert 34 can be flushly mounted to vertical member 40 . threaded inserts 84 , 86 , 88 are flush mounted to mounting side 82 . as shown in fig2 , fasteners , and , preferably , shoulder screws 90 , 92 , are threaded into threaded inserts 84 , 88 . shoulder screws 90 , 92 include heads 94 , 96 and shoulder members 98 , 100 . preferably , the shoulder screws are # 14 - 10 type a , blunt tip shoulder screws sold by modular systems , inc . of fruitport , mich . heads 94 , 96 are sized in order that they may fit through openings 56 , 58 but not fit through rib members 64 , 66 . accordingly , to attach ornamental corner insert 34 to back plate 30 , the heads 94 , 96 of shoulder screws 90 , 92 are inserted into openings 56 , 58 . the ornamental corner insert 34 is then moved from left to right , as viewed in fig2 , such that the protrusions 68 , 70 on rib members 64 , 66 positively engage the shoulder screws 90 , 92 to hold them in slots 60 , 62 . to remove the ornamental corner insert 34 and possibly replace it with one of a different design , the ornamental corner insert 34 is moved from right to left until heads 94 , 96 are allowed to escape through openings 56 , 58 . advantageously , the design of back plate 30 and attachment clip 32 may accommodate former ornamental corner inserts which do not incorporate shoulder screws 90 , 92 . these former ornamental corner inserts typically have only a threaded rod protruding from its back for securing it to the corner of a casket . as such and with reference to fig6 , a former ornamental corner insert 112 is shown without inserts 84 , 88 . in this configuration , only threaded insert is present to receive threaded rod 114 . to install ornamental corner insert 112 to casket 10 , threaded rod 114 is inserted through indexing member 49 and throughhole 22 of brace 20 . wing nut 118 threadingly engages threaded rod 114 to secure ornamental corner insert 112 to back plate 30 . former ornamental corner insert 112 is representative of the corner inserts which must be rigidly affixed to the corner of caskets . judicious placement of indexing member 49 allows the former style ornamental corner inserts 112 to be used with attachment clip 32 and back plate 30 , i . e . be retrofitted according to the principles of the present invention . alternatively threaded insert 86 can be eliminated , with the threaded screw being screwed directly into the wood , plastic or metal insert . advantageously , ornamental corner insert 34 may be installed onto casket corners not incorporating back plate 30 and attachment clip 32 . that is , ornamental corner insert 34 of the present invention is not restricted to use with only back plate 30 and attachment clip 32 . importantly , ornamental corner insert 34 may be used on caskets which were initially constructed using former ornamental corner insert 112 . accordingly and with reference to fig7 , the ornamental corner insert 34 is shown affixed to a back plate 124 . back plate 124 is representative of back plates used previously in conjunction with former ornamental corner insert 112 . back plate 124 is similar to back plate 30 ; however , back plate 124 does not include elongated groove 42 . because back plate 124 does not include a place to secure attachment clip 32 , shoulder screws 90 , 92 cannot be used to secure ornamental corner insert 34 to back plate 124 . as such , shoulder screws 90 , 92 are removed and threaded rod 114 is threaded into threaded insert 86 . to install ornamental corner insert 34 to back plate 124 , threaded rod 114 is inserted through throughhole 44 and throughhole 22 and held in place with threaded wing nut 118 . the benefit of using the shoulder screws in conjunction with attachment clip 32 is that the ornamental corner insert 34 can be installed and removed quickly and efficiently without having to access the interior of the casket 10 . the embodiments shown in fig5 and 6 , however , require the use of hand tools and access to the interior of the casket 10 in order that wing nut 118 can be threaded onto threaded rod 114 . the embodiments referenced in fig2 - 7 are preferably used with a casket 10 constructed of wood . another embodiment of the present invention is used on a casket formed from sheet metal , e . g ., steel or aluminum . accordingly , and with reference to fig8 , a casket 128 made from steel is shown with a corner attachment mechanism 130 . the corner attachment mechanism 130 includes a base or mounting member 132 , a back plate 134 and an ornamental corner insert 136 . base 132 is affixed to the corner of casket 128 with fasteners , preferably screws , 138 . base 132 and back plate are preferably made from plastic . integrally molded within back plate 134 are keyhole grooves 140 , 142 which are similar to the geometry of keyhole grooves 52 , 54 . more specifically , keyhole grooves 140 , 142 include openings 144 , 146 and slots 148 , 150 which are similar to openings 56 , 58 and slots 60 , 62 . back plate 134 also includes a plurality of oppositely disposed fastening members 152 which engage oppositely disposed slots 154 along the vertical edges of base 132 to secure back plate 134 to base 132 . in this embodiment , back plate 134 does not include throughhole 44 . as such , the ornamental corner insert 112 , having only threaded insert 86 , cannot be attached to base 132 . like the attachment clip 32 of fig2 , the back plate 134 permits the ornamental corner insert 136 to be installed from left to right and removed from right to left . for example , to install the ornamental corner insert 136 , the heads 94 , 96 are inserted into openings 144 , 146 of keyhole grooves 140 , 142 and slid from left to right across slots 148 , 150 . referring now to fig1 , there is illustrated yet another embodiment of the present invention for use on sheet metal caskets . with like numbers representing like elements , the primary difference between the fig1 embodiment and the fig8 embodiment is the design and construction of the grooves 140 ′ and 142 ′ in the plate 134 . more particularly , groove 140 ′ includes a first keyhole portion comprising opening 144 ′ and slot 148 ′, and a second non - keyhole portion comprising slot 149 ′. similarly , groove 142 ′ includes a first keyhole portion comprising opening 146 ′ and slot 150 ′, and a second non - keyhole portion comprising slot 151 ′. as illustrated , the longitudinal axis of slot 149 ′ is perpendicular to the longitudinal axis of slot 148 ′. similarly , the longitudinal axis of slot 151 ′ is perpendicular to the longitudinal axis of slot 150 ′. to install the casket corner ornament 136 , the heads 94 , 96 are inserted into openings 144 ′, 146 ′ of grooves 140 ′, 142 ′; ornament 136 is then moved generally parallel to a plane defined by plate 134 from left to right thus sliding heads 94 , 96 from left to right in slots 148 ′, 150 ′. the ornament 136 is then moved again generally parallel to the plane defined by plate 134 downwardly thus sliding heads 94 , 96 down in slots 149 ′, 151 ′. the multi - direction movement to install ornament 136 in the fig1 embodiment reduces the potential for the ornament 136 to become inadvertently dislodged from plate 134 . while the two directions of motion to install the ornament 136 in the fig1 embodiment have been illustrated as being perpendicular , the openings , grooves , etc . could as well be configured such that the directions of motion were not perpendicular , but simply non - parallel . furthermore , while the motions to install ornament 136 in the fig1 embodiment have been illustrated as being rectilinear , the openings , grooves , etc . could as well be configured such that the motions were not rectilinear , but curvilinear . all such variations are within the scope of the present invention . while the present invention has been illustrated by a description of various preferred embodiments and while these embodiments have been described in considerable detail in order to describe the best mode of practicing the invention , it is not the intention of the applicants to restrict or in any way limit the scope of the appended claims to such detail . additional advantages and modifications within the spirit and scope of the invention will readily appear to those skilled in the art . the invention itself should only be defined by the appended claims , wherein we claim :
