Security rail attachment for a bed

A combination of bed and a security rail for attachment to the bed the bed comprising a bed frame having side rails defined by a pair of angle irons each having a vertical flange and a horizontal flange, the security rail comprising a vertical post having a foot at a lower end for resting on a ground surface adjacent the bed frame, an elongate attachment member connected to the post and extending therefrom substantially at right angle thereto, each end of the attachment member having mounted thereon a respective one of a pair of clamping brackets each for clamped attachment to a respective one of said angle irons, a rail member including a post portion and a rail portion extending outwardly from the post portion to one side thereof, the post portion being arranged for mounting in the post to be supported thereby in vertical orientation with the rail portion extending therefrom in substantially horizontal orientation, the post portion being rotatable about a vertical axis of the post to move the horizontal rail portion between a first position in which it extends outwardly from the bed at a right angle to the adjacent side of the bed and a second position in which it extends parallel to the adjacent side of the bed, and latching means for latching the post portion in said first and second positions, said latching means comprising a horizontal pin, means mounting the pin in the post and arranged for location of the pin at different height within the post, a lowermost surface of the post portion which is arranged for cooperation with the pin, the lowermost surface having two horizontal transverse notches thereacross arranged mutually at right angles such that a selected one of the notches can be engaged on the pin by downward vertical movement of the post portion, and means for limiting upward movement of the post portion relative to the post, the distance of upward movement being sufficient to allow release of the pin from the notches, each notch being shaped in cross section to define a first U-shaped portion having parallel sides shaped to engage over and receive the pin therein and a second mouth portion having diverging sides communicating with said parallel sides such that the mouth portion guides the pin into the notch to cause movement of the post portion to the required orientation, said means for limiting upward movement comprising a spring hook member engageable under the pin, the spring hook member being shaped so as to deflectable to pass over the pin when inserted into the post.
