A wheelchair device made for fully supporting the feet of the user. It spans the space between the left and right foot rest pedals. It is comprised of a length of a sleeve made of a durable material and configured with at least one open end; an elongated cross-section; a top surface tread; an essentially smooth bottom surface featuring a shelf; and an internal aperture wherein one of the end with an internal aperture of the device may slide over and essentially encase either of the foot plates of the wheelchair and wherein the opposite end with the recess may rest on the other un-encased foot plate which results in a bridge of the space between the two pedals. An alternative embodiment features an extension tube for various widths of wheelchairs.

1. A device used in cooperation with a wheelchair for fully supporting a pair of feet of a user, the device comprised of: (a) a partially enclosed sleeve having a length, a height, a width, a thickness and two opposing ends, the partially enclosed sleeve made of a durable material, and wherein: (i)
1. A device used in cooperation with a wheelchair for fully supporting a pair of feet of a user, the device comprised of: (a) a partially enclosed sleeve having a length, a height, a width, a thickness and two opposing ends, the partially enclosed sleeve made of a durable material, and wherein: (i) a first end of the two opposing ends is an open tubular end, the open tubular end having a top with a top surface, a bottom with a bottom surface and a pair of sides;(ii) a second end of the two opposing ends is a shelf end and is opposite the open tubular end, the shelf end having a smooth bottom surface and a top surface and being contiguous and connected with the top surface of the open tubular end; the shelf end having a pair of sides, each side of the shelf end being contiguous with the sides of the open tubular end; and the top surface of the shelf end and the pair of sides of the shelf end forming a shelf; and(iii) the contiguous top surface of the two opposing ends of the partially enclosed sleeve includes at least one feature; and the device further comprised of:(b) a tubular enclosed sleeve having a length, a height, a width and a thickness, the tubular enclosed sleeve having two ends, a top with a top surface with at least one feature, a bottom with a bottom surface, and a pair of sides, the tubular enclosed sleeve made of a durable material, and the height and the width of the tubular enclosed sleeve, in cross-section, is less than the height and the width of the partially enclosed sleeve, in cross-section, such that the tubular enclosed sleeve is configured to telescope within an interior of the open tubular end of the partially enclosed sleeve, and wherein the tubular enclosed sleeve is configured to slide over and encase one of a pair of foot plates of the wheelchair and wherein the partially enclosed sleeve is configured to rest on the other of the pair of foot plates which results in the device bridging a space between the pair of foot plates. 2. The device according to claim 1, wherein the at least one feature of the contiguous top surface of the two opposing ends of the partially enclosed sleeve is a series of treads. 3. The device according to claim 1, wherein the at least one feature of the contiguous top surface of the two opposing ends of the partially enclosed sleeve is a written word. 4. The device according to claim 1, wherein, for both the partially enclosed sleeve and the tubular enclosed sleeve, the top surfaces, the pair of sides and the bottom surfaces are joined by a series of corners at a junction of the top and bottom surfaces with each of the sides. 5. The device according to claim 4, wherein the series of corners include a beveled configuration. 6. The device according to claim 4, wherein the series of corners include a radiused configuration. 7. The device according to claim 1, wherein the bottom of the partially enclosed sleeve is further comprised of a control slot and the feature of the top surface of the tubular enclosed sleeve is a mating protrusion engageable with the control slot. 8. The device according to claim 1, wherein the durable material is a metal. 9. The device according to claim 8, wherein the metal is selected from a group consisting of stainless steel, aluminum, pot metal, and steel alloys. 10. The device in claim 9, wherein the at least one feature is a surface finish on the metal selected from a group consisting of chrome plating, powder coating or painting. 11. The device according to claim 1, wherein the durable material is a composite material. 12. The device according to claim 11, wherein the composite material is a reinforced plastic. 13. The device according to claim 12, wherein the reinforced plastic is a material composition selected from a group consisting of a polyester, a poly carbonate, an estralon, co-polyesters, a poly propylene, an acrylic, a poly urethane, and a urethane composition. 14. The device according to claim 11, wherein the composite material is a fiber-containing material selected from a group consisting of cardboard, fiberboard, and pressed wood-board. 15. A device used in cooperation with a wheelchair for fully supporting a pair of feet of a user, the device comprised of: (a) a tubular enclosed sleeve having a length, a height, a width and a thickness, the tubular enclosed sleeve having two ends, a top with features, a bottom and a pair of sides, and wherein the top, the bottom and the pair of sides all are made of a durable material, and the height and the width of the tubular enclosed sleeve, in cross-section, are sized to telescopically receive a Cee-shaped section;(b) a Cee-shaped section having a length, a height, a width and a thickness, the Cee-shaped section made of a durable material, the height and width of the Cee-shaped section, in cross-section, being less than the height and width of the tubular enclosed sleeve, in cross-section, such that the Cee-shaped section is slidable to telescope within an interior of the tubular enclosed sleeve, and wherein the Cee-shaped section includes: (i) a top surface with a pair of opposite ends;(ii) a pair of side surfaces extending downward from the top surface of the Cee-shaped section; and(iii) a means to connect the pair of side surfaces to the top surface; andwherein the tubular enclosed sleeve is configured to slide over and encase one of a pair of foot plates of the wheelchair and wherein the Cee-shaped section is configured to rest on the other of the pair of foot plates of the wheelchair which results in the device bridging a space between the pair of foot plates.
