The elevator block comprises top and bottom ends that are non-parallel planar surfaces. The planar surface of the top end is inclined to allow for proper mating of the top end of the elevator block with a bed leg in the bed's raised position. Provision is also made for a removable insert in a cavity of the top end of the elevator block, so that bed legs can sit either within the cavity for increased stability or upon the top of the insert, depending upon the size of the bed leg. The use of slip-resistant materials on the surfaces contacting either the floor or bed leg also add to the stability of the bed in the raised position. ## Claims ### Claim 1 An elevator block, for use in raising one end of a conventional bed supported by a plurality of legs resting on a horizontal bed supporting surface, comprising: (a) a top end adapted to support a corresponding leg of the bed and having a substantially planar surface; (b) a bottom end adapted to rest on said bed support surface and having a substantially planar surface; (c) said top end having a front edge and a rear edge, with the rear edge defined to be proximately located nearest the uppermost portion of the raised end of said conventional bed; said planar surface of the top end being non-parallel to the planar surface of bottom end; said planar surface of the top end being an inclined plane such that the height from the bottom end to the front edge is less than the height from the bottom end to the rear edge and wherein the top end further comprises: (d) a cavity comprising a base; (e) an opening in said front edge; (f) an insert which is sized so that it may be removably mated within said cavity; (g) said insert having a protrusion which fits within said opening of said front edge to allow the insert to be grasped and removed from the cavity. ### Claim 2 (depends on 1) The elevator block according to claim 1, wherein said bottom end has a surface area greater than the surface area of said top end. ### Claim 3 (depends on 1) The elevator block according to claim 1, wherein the planar surface of the top end is inclined from horizontal between about 1 and 8 degrees. ### Claim 4 (depends on 1) The elevator block according to claim 1, wherein the distance from the bottom end to the front edge is between about 4 and 9 inches. ### Claim 5 (depends on 1) The elevator block according to claim 1 wherein the elevator block is used in conjunction with other elevator blocks of the same plurality as the number of legs supporting one end of said bed to form a bed raising system. ### Claim 6 (depends on 1) The elevator block according to claim 1 wherein the planar surface of the top end is parallel to the planar surface defined by the bottom of all of the bed support legs when said elevator blocks are used and one end of the bed is in its raised position. ### Claim 7 (depends on 1) The elevator block according to claim 1 wherein the planar surface of the bottom end has a slip-resistant surface to help keep the elevator block from slipping during use. ### Claim 8 (depends on 1) The elevator block according to claim 1 wherein the top end further includes: (a) a cavity comprising a base, upon which said bed leg sits during use; (b) said cavity being of sufficient size to allow during use for the insertion of said bed leg; and (c) said base being a substantially planar surface and nonparallel to the planar surface of the bottom end of the elevator block (d) said base further being substantially parallel to the plane of the bed when the bed is in its raised position. ### Claim 9 (depends on 1) The elevator block according to claim 1 wherein said protrusion further includes grooves to allow the insert to be easily grasped and removed from the cavity. ### Claim 10 (depends on 1) The elevator block according to claim 1, wherein said insert further includes front and rear side walls that are tapered. ### Claim 11 (depends on 1) The elevator block according to claim 1, wherein said insert further includes an upper surface which comprises a slip-resistance surface adapted to help keep the bed leg from slipping during use. ### Claim 12 An elevator block for use in raising one end of a conventional bed supported by a plurality of legs resting on a horizontal bed supporting surface, comprising: (a) a top end adapted to support a corresponding leg of the bed and having a substantially planar surface; (b) a bottom end adapted to rest on said bed support surface; (c) said top end having a front edge and a rear edge, with the rear edge defined to be proximately located nearest the uppermost portion of the raised end of said conventional bed; said planar surface of top end being non-parallel to planar surface of bottom end; said planar surface of top end being an inclined place such that the height from the bottom end to the front edge is less than the height from the bottom end to the rear edge; (d) said top end further including a cavity comprising a base, an opening in said front edge, an insert which is sized so that it may be removably mated within said cavity, said insert having a protrusion which fits within said opening of said front edge to allow the insert to be grasped and removed from the cavity; (e) said protrusion further including grooves to allow the insert to be easily grasped and removed from the cavity; (f) said insert further including a front and rear sidewalls that are tapered; and (g) said insert further including an upper surface which comprises a slip-resistance surface adapted to help keep the bed leg from slipping during use.
