Title: Casket

Description:
BACKGROUND 
     The present invention relates generally to caskets and more specifically to caskets which do not require the use of nails or hardware of any kind. 
     Certain religious requirements exist that caskets used in burial required no nails, hardware, or non-naturally occurring material of any kind. With the increasing costs of labor and material in constructing such caskets, a need has arisen for a casket which, while meeting these religious requirements, can be stored flat prior to use, can be easily assembled by two people, and can be easily manufactured from inexpensive material, while still allowing the assembled casket to be highly functional, yet be of an aesthetic appearance, and allow a dignified burial, while avoiding excessive costs. 
     SUMMARY 
     The casket of the present invention solves these and other problems by providing, in the preferred embodiment, a bottom, a first side, a second side, a first end, a second end, and a top. The parts of the casket, according to the teachings of the present invention interfit, in a fashion that the assembly of the last part locks all preceeding parts and prevents movement of the preceeding parts in any direction to form a rigid, unitary, complete casket obviating the necessity of any further fastening elements of any kind. 
     Also, the casket of the present invention further provides, in the preferred embodiment, handle members comprised of rope members that are attached to the casket without the use of knots. 
     It is thus a primary object of the present invention to provide a novel casket. 
     It is further an object of the present invention to provide such a casket that meets certain religious requirements that no nails, hardware, or non-naturally occurring material be used. 
     It is further an object of the present invention to provide such a casket having components that can be stored flat in a carton prior to use, are easily manufactured from inexpensive material, and can be easily assembled by two people, while still allowing the assembled casket to be highly functional, yet be of an aesthetic appearance. 
     It is further an object of the present invention to provide such a casket which allows a dignified burial while avoiding excessive costs. 
     These and further objects and advantages of the present invention will become clearer in light of the following detailed description of an illustrative embodiment of this invention described in connection with the drawings.

Grooves 94 and 96 are formed on the inside surface 92 of top 22. Top 22 further includes a first bore 98, having a circular cross-section in the preferred embodiment, extending from surface 90 to surface 92 at a location corresponding to bore 65 of end 18 when casket 10 is in an assembled relation, as will be explained further hereinafter. Top 22 additionally includes a second bore 100, having a circular cross-section in the preferred embodiment, extending from surface 90 to surface 92 at a location corresponding to bore 80 of end 20 when casket 10 is in an assembled relation, as will be explained further hereinafter. 
     A first dowel 102 is provided corresponding to and for receipt within bores 65 and 98, and further, a second dowel 104 is provided corresponding to and for receipt in bores 80 and 100, for purposes to be explained further hereinafter. 
     Handle members 106 are further provided and located along the length of casket 10 and, in the preferred embodiment, include six members 106. Handle members 106 include a rope member 108, having a first end, and include a second end and a first aperture 110 and a second aperture 112 spaced horizontally from aperture 110, both formed in sides 14 or 16. Members 106 further include a third aperture 114 and a fourth aperture 116 spaced from aperture 114 formed in bottom 12. Apertures 114 and 116 are located along a line parallel to end edges 28 and 30 of bottom 12 corresponding to aperture 110. Members 106 further include a fifth aperture 118 and a sixth aperture 120 spaced from aperture 118 formed in bottom 12. Apertures 118 and 120 are located along a line parallel to end edges 28 and 30 of bottom 12 corresponding to aperture 112. 
     In the preferred embodiment of the present invention, the first end of rope member 108 is located within aperture 114 and extends exteriorly of casket 10. Rope member 108 is then threaded through aperture 116 into the interior of casket 10, through aperture 110 to the exterior of casket 10, through aperture 112 into the interior of casket 10, and through aperture 120 to the exterior of casket 10. The second end of rope member 108 is located in aperture 118. It should then be noted that rope member 108 is cinched between apertures 114 and 116 and apertures 118 and 120 such that no knots are required on the first and second ends of rope member 108. It should then be noted that rope member 108 should be of a sufficient length so that a loop is formed exteriorly or outside of casket 10 between apertures 110 and 112 for grasping by a person for use as a handle in carrying casket 10. 
     Now that the structural details of the components of casket 10 have been set forth, the method of assembly will be explained and the advantages of the present invention can better be appreciated. Bottom surface 34 of bottom 12 is first set on a flat surface, and in the preferred embodiment, is set on a block or other object having an area considerably lesser than the area of bottom surface 34. Side 14 is then positioned such that first side edge 24 of bottom 12 aligns with groove 50 of first side 14. Side 14 is then slid onto bottom 12 such that edge 24 of bottom 12 is longitudinally slidably received within groove 50 of side 14. Similarly, second side 16 is positioned such that second side edge 26 of bottom 12 aligns with groove 50a of second side 16. Side 16 is then slid onto bottom 12 such that second side edge 26 of bottom 12 is longitudinally slidably received within groove 50a of side 16. It should then be noted that the dove tailed edges 24 and 26 of bottom 12 and the dove tailed grooves 50 and 50a of sides 14 and 16 allow for longitudinally, slidably interlocking of sides 14 and 16 to bottom 12 and for preventing movement of sides 14 and 16 relative to bottom 12 in all directions other than its longitudinal. 
     It should be noted that sides 14 and 16 should be positioned on bottom 12 such that end edge 28 of bottom 12 is located on the side of grooves 51 and 51a opposite ends 42 and 42a of sides 14 and 16. First end 18 is then positioned such that first side edge 58 aligns with groove 51 of side 14 and second side edge 60 aligns with groove 51a of side 16. End 18 is then slid within sides 14 and 16 such that edges 58 and 60 of end 18 are longitudinally slidably received within grooves 51 and 51a of sides 14 and 16, respectively. It should then be noted that the dove tailed edges 58 and 60 of end 18 and dove tailed grooves 51 and 51a of side 14 and 16 allow for longitudinally, slidably interlocking of end 18 to sides 14 and 16, respectively and for preventing movement of end 18 relative to sides 14 and 16 in all directions other than its longitudinal. 
     At this time, bottom 12 can be further slid within sides 14 and 16 such that end edges 28 of bottom 12 is located and captured within groove 66 of end 18. It should then be noted that groove 66 of end 18 has a shape complementary to the shape of end edge 28 of bottom 12. Additionally, it should be noticed that end edge 28 of bottom 12 is positioned within groove 66 of end 18 for blocking end 18 such that longitudinal movement of end 18 within sides 14 and 16 is prevented. Furthermore, end edge 28 of bottom 12 abuts end 18 within groove 66 for blocking bottom 12 such that bottom 12 is prevented from being longitudinally, slidably moved within sides 14 and 16 in a first direction towards end 18. 
     End 20 is then positioned such that first side edge 72 is aligned with groove 52 of side 14 and second side edge 74 is aligned with groove 52a of side 16. At this time, end 20 is slid within sides 14 and 16 such that edges 72 and 74 are longitudinally slidably received within grooves 52 and 52a of sides 14 and 16, respectively. End 20 is positioned such that bottom edge 70 of end 20 is located within groove 36 of bottom 12. It should then be noted that dove tailed edges 72 and 74 and dove tailed grooves 52 and 52a of sides 14 and 16 allow for longitudinally, slidably interlocking of end 20 to sides 14 and 16 of casket 10 and for preventing movement of end 20 relative to sides 14 and 16 in all directions other than its longitudinal. Additionally, bottom edge 70 of end 20 is positioned within groove 36 of bottom 12 for blocking bottom 12 such that longitudinal movement of bottom 12 within sides 14 and 16 is prevented. It should then also be noted that since edge 70 of end 20 abuts with groove 36 of bottom 12, end 20 is prevented from moving beyond bottom 12. 
     Top 22 can then be positioned such that edge 38 of side 14 aligns with groove 94 and edge 38a of side 16 aligns with groove 96 of top 22. Top 22 can then be slid such that edges 38 and 38a of sides 14 and 16 are longitudinally slidably received within grooves 94 and 96 of top 22, respectively. It should then be noted that dove tailed edges 38 and 38a of sides 14 and 16 and dove tailed grooves 94 and 96 of top 22 allow for longitudinally, slidably interconnecting of top 22 to sides 14 and 16 and for preventing movement of top 22 relative to sides 14 and 16 in all directions other than its longitudinal. It should then also be noted that edge 78 of end 20 abuts with top 22 and therefore prevents movement of end 20 past top 22. 
     Dowel 102 can then be positioned within bore 98 of top 22 and bore 65 of end 18 and dowel 104 can be positioned within bore 100 of top 22 and bore 80 of end 20. Dowels 102 and 104 and bores 65, 80, 98, and 100 therefore allow for blocking longitudinal movement of top 22 with respect to sides 14 and 16 and therefore stop the longitudinal movement of top 22 with respect to sides 14 and 16 of casket 10. 
     It should now be noted that, according to the teachings of the present invention, the bottom, sides, ends, and top interfit in a fashion that the assembly of the last part, for example top 22 as shown in the preferred embodiment, locks all preceeding parts, for example as shown in the preferred embodiment, bottom 12, sides 14 and 16, and ends 18 and 20, and prevents movement of the preceeding parts in any of their longitudinal directions to form a rigid, unitary, complete casket obviating the necessity of any further fastening elements of any kind. It should then be further noted that the longitudinal movement of the last part, for example top 22 as shown in the preferred embodiment, can further be blocked, as by dowels 102 and 104 and bores 65, 80, 98, and 100 as in the preferred embodiment. 
     It can then be appreciated that the present invention allows a dignified burial while avoiding excessive cost. The present invention further meets certain religious requirements that no nails, hardware, or other materials not naturally occurring be used in caskets. 
     Additionally, it should be noted that the components of the casket according to the teachings of the present invention can be stored flat in a carton prior to use, are easily manufactured from inexpensive material, and can be easily assembled by two people, while still allowing the assembled casket to be highly functional, yet be of an aesthetic appearance. 
     Now that the basic teachings of the present invention have been explained, many extensions and variations will be obvious to one having ordinary skill in the art. For example, although, in the preferred embodiment, dove tailed edges and grooves are shown to allow for longitudinally slidably interconnecting of the parts and for preventing movement of the parts in all directions other than their longitudinal, other types of connections will become obvious to a person skilled in the art after the present invention is known and understood. 
     Furthermore, although in the preferred embodiment, end 18 interfits with bottom 12 and sides 14 and 16 such that end edge 28 of bottom 12 extends into groove 66 of end 18 for providing a strong connection, end 18 could interfit with bottom 12 and sides 14 and 16 in a manner analogous to the interfitting of end 20 thereto. Thus, ends 18 and 20 could be identical in design and size. Additionally, it should be noted that ends 18 and 20 could be positioned such the end edge 28 of bottom 12 abuts against surface 64 of end 18, end edge 30 of bottom 12 abuts against surface 76 of end 20, bottom edge 56 of end 18 and bottom edge 70 of end 20 abut against the material located between grooves 50 and 50a and bottom edges 40 and 40a of sides 14 and 16, respectively, and top edge 54 of end 18 and top edge 68 of end 20 abut against inside surface 92 of top 22. 
     Likewise, although casket 10 of the preferred embodiment according to the teachings of the present invention is shown as not requiring nails or hardware of any kind, caskets according to the teachings of the present invention can additionally include hardware or nails as desired. For example, screws, nails, or other fastening devices can be used in substitution or in addition to dowels 102 or 104, if acceptable. 
     Although casket 10 of the preferred embodiment according to the teachings of the present invention includes handle members 106 as disclosed, handle members may be omitted or handle members or other types can be used alone or in addition to handle members 106 as shown in the preferred embodiment of the present invention. 
     Thus, since the invention disclosed herein may be embodied in other specific forms without departing from the spirit or the general characteristics thereof, some of which forms have been indicated, the embodiments described herein are to be considered in all respects illustrative and not restrictive. The scope of the invention is indicated by the appended claims, rather than by the foregoing description and all changes which come within the meaning and range of equivalency of the claims are intended to be embraced therein.
