RICHARD B.ESTERDAHL United States Patent 3,534,451 MAGNETIC CLOSURE FOR CASKET Richard B. Esterdahl, RR. 3, Box 161313, Prophetstown, Ill. 61277 Filed Apr. 21, 1967, Ser. No. 632,776 Int. Cl.A61g 17/00 US. CI. 2716 9 Claims ABSTRACT OF THE DISCLOSURE On a coflin, a magnetic strip mounted around the rectangular upper edge of the lower box section adapted to contact and close the area of the juncture between the cover panels and the box section, and a magnetic strip fixed to the underside of the foot panel with a portion thereof extending toward and underlying the edge portion of the head panel to completely close the juncture between the head and foot panels; the magnetic strip around the upper edge being composed of a flexible envelope with a longitudinally extending permanent magnet retained therein that causes the upper portion of the envelope to engage and hold against the lower edges of the foot and head panels.
BACKGROUND OF THE INVENTION Field of the invention-This invention relates to a coflin and more particularly to a magnetic latching strip that extends between the juncture of the head and foot panels, and between the head and foot panels and the upper edge of the lower box portion for latching and closing the respective junctures.
Description of the prior art-It has heretofore been known to have magnetic latches for latching a door closed on a box. Probably the most common use being on ice boxes on which a mganet is carried on the door and is attracted to the metal flange on the box. It is also old in cofiins to provide rubber seals at the juncture between the cover and the box portions.
Caskets or coflins are normally made of metal with parts of the casket being formed by dies and by stamping. The problem with so forming a casket is that the finished parts are often inaccurate and generally, when assembled, the junctures between the lid or cover and the box are not completely closed. The same is true relative to the juncture between the foot and head panels of the cover. So pronounced is this feature that oftentimes one seated with an eye level at the juncture height may see completely through the casket at the juncture. This, of course, is distracting and undignified, and it creates a very unprofessional image of the undertaker and his establishment. Also, due to the poor fitting of the parts, and particularly the normal latch parts, the casket will often rattle during movement or transport, thereby distracting from the dignity of the occasion. Even the noise of the latch catching when the cover closes may offend sensitive people.
SUMMARY With the above in mind, it is the primary purpose and object of the invention to provide a magnetic seal com pletely around the upper periphery of the lower box section and at the juncture between the head and foot panels of the cover. The magnetic seal around the periphery is composed of an elongated flexible envelope having a bottom side fixed to the top edge of the box with a flexible elongated permanent magnet retained therein. Consequently, as the cover portions are closed on the box portion, the magnetic attraction between the top portion and permanent magnet will force the envelope to expand and ice seal or press against the adjoining edges of the cover portions. Consequently, any gaps due to irregularity in the adjoining edges will be filled by the envelope. The magnetic attraction between the cover and box portions does, of course, operate as a latch.
It is a further object of the invention to provide that the above magnetic seal may be utilized when desired on a casket. The envelope is vinyl and consequently since it fits tightly against the adjoining edge, it does in fact operate as a relatively cheap vapor and moisture seal at the juncture. Therefore, when the latter is desired on a conventional type casket, the magnetic seal may be applied to the top of the box. By having the envelope so that it may expand, the magnetic seal may be compressed between the hinge plates connecting the cover and box portions and may expand to substantially retain the seal in areas offset from the seal.

DESCRIPTION OF THE PREFERRED EMBODIMENT The casket herein shown is composed of alower box portion 10 having front andrear wall structures 11, 12 and oppositeend wall structures 13, 14. A floor panel, not shown, interconnects the lower edges of the wall structures 11-14. The structures 11'14 are normally formed by a die and have relatively large inaccuracies or tolerances. The ends of the respective wall structures are normally welded to one another.
The walls 1114 are each provided with an outwardly extendinginclined portion 15 at its upper portion that is integral with an upper uprightperipheral panel section 16 which terminates at upper edges defined by inwardly extending flanges orpanel sections 17. For structural strength eachflange 17 has an integral innervertical section 18 and an outwardly projecting underflange 19.
A casket cover or lid composed of ahead panel 20 and afoot panel 21 is hingedly connected at 22 to theupper flange 17 of therear wall 12. Both the foot and head panels haveboxlike edge flanges 23 at their front and rear edges and at respective ends above theend walls 13, 14. The box flanges include a downwardly facing horizontal panel orflange section 24. Thepanels 20, 21 have intermediate adjoining edges defined byvertical panels 26, 27 lying adjacent one another. Inner horizontal flanges orpanels 28, 29 extend toward the respective ends from the lower edges of thevertical panel sections 26, 27.
Thehinges 22 are composed ofhinge plates 30, 31 spot welded to the upper surface of thehorizontal flange 17 and to the lower surface of theflange 24. Ahinge pin 32 pivotally interconnects theplates 30, 31.
Extending completely around theperipheral flange 17 is a magnetic latch or seal indicated in its entirety by thereference numeral 35. The seal is composed of a vinyl or flexible envelope composed of alower vinyl plate 37 that may be glued to the upper surface of thehorizontal flange 17, a central expandable pleatedportion 38, and
an upperhorizontal sleeve portion 39. Thesleeve 39 contains apermanent magnet 40 therein of a vinyl base construction. Theseal 35 is glued or otherwise fixed to the upper edge orflange 17 of the respective walls 11-14. Theseal 35 extends over and is glued also to thehinge plates 30.
At the juncture between thepanels 20, 21 and along the edges offlanges 28, 29, there is provided astrip 41 of magnetic material that half underlies and is connected to theflange 29 either by gluing or by a strong magnetic attraction to theflange 29. Half of thestrip 41 projects outwardly beyond thevertical panel 27. When the head panel is closed as shown in FIG. 5, theflanges 28, 29 may be vertically misaligned. Thestrip 41 will bend sufliciently, due to its magnetic attraction to flange 28, to cover the flaw of misalignment.
In actual construction, theflanges 17, 24 will in many instances not be perfectly horizontal in either the transverse or longitudinal direction. However, upon the cover portion being closed, thepleated portion 38 of the envelope will permit the upper sleeve andpermanent magnet 40 to bear tightly against theflange 24 regardless of misalignment or imperfections due to manufacturing flaws. Therefore, themagnet latch 35 automatically compensates for the flaws and tolerances of manufacture.
The gap between theflanges 17, 24 along therear wall 12 is greater than along the forward wall 11. This is due somewhat to the hinge plates being fixed to the surfaces of theflanges 17, 24. Upon the cover portions being closed, as shown in FIG. 4, theseal 35 will be completely compressed. However, the pleated portion will permit extension along the edges between thehinges 22 to thereby maintain the seal along the portions of the edges between the hinge plates.
