1. A bed rail having a guard frame barrier that can be tucked between a mattress and box spring of a bed and that can further be disposed at a side of the bed and upwardly beyond a sleeping surface of the bed to prevent a person from falling out of bed, comprising:
a) a base support and a guard frame where the guard frame has an operating position in a first plane adjacent to a proximal end of the base support and a stored position in a second plane adjacent to proximal and distal ends of the base support, wherein the guard frame is connected to the base support; b) wherein the guard frame includes a first unit, with the first unit comprising first, second, and third support members, with the third support member being transverse to the first and second support members, with each of the first, second, and third support members having a main body diameter, with the main body diameter of the third support member being different from the main body diameters of the first and second support members; c) wherein the guard frame includes a second unit, with the second unit comprising fourth, fifth, and sixth support members, with the sixth support member being transverse to the fourth and fifth support members, with each of the fourth, fifth, and sixth support members having a main body diameter, with the main body diameter of the sixth support member being different from the main body diameters of the third and fourth support members, with the main body diameter of the sixth support member being the same as the main body diameter of the third support member; d) wherein the guard frame includes a third unit, with the third unit comprising a seventh support member having first and second elongate sections extending relative to each other at an angle, with the third unit having a main body diameter, with the main body diameter of the third unit being the same as the main body diameters of the first and fourth support members; e) wherein the guard frame includes a fourth unit, with the fourth unit comprising an eighth support member having third and fourth elongate sections extending relative to each other at an angle, with the fourth unit having a main body diameter, with the main body diameter of the fourth unit being the same as the main body diameters of the first and fourth support members, with the main body diameter of the fourth unit being the same as the main body diameter of the third unit; f) wherein the first unit is connected to the second unit; g) wherein the first unit is further connected to one of the third and fourth units; h) wherein the second unit is further connected to the other of the third and fourth units; i) wherein the first support member of the first unit is connected to the fourth support member of the second unit by a first tube portion mating with a second tube portion, with one of the first and second tube portions having a transverse piece engaged by the other of the first and second tube portions; j) wherein the second support member of the first unit is connected to the fifth support member of the second unit by a third tube portion mating with a fourth tube portion, with the fourth tube portion having an annular stop spaced from an end of the fourth tube portion, with the fourth tube portion being a portion between the end of the fourth tube portion and the annular stop, with the fourth tube portion being solid and continuous; k) wherein the third support member of the first unit is connected to one of the third and fourth units by a fifth tube portion mating with a sixth tube portion, with one of the fifth and sixth tube portions having a transverse piece engaged by the other of the fifth and sixth tube portions; l) wherein the sixth support member of the second unit is connected to the other of the third and fourth units by a seventh tube portion mating with an eighth tube portion, with one of the seventh and eighth tube portions having a transverse piece engaged by the other of the fifth and sixth tube portions; and m) wherein the third unit is connected to the fourth unit. |
