Abstract

A floor-mounted bed locator is used to removably retain a hospital bed of the type which carries electrically powered equipment having an electric plug. The locator comprises an electrical socket for receiving the plug, and a disconnector for ejecting the plug from the socket when the bed is removed from the locator. The disconnector includes at least one ejector pin disposed beneath the plug when the latter is connected to the socket, and a movably mounted treadle engageable and moved by a castor of the bed as the latter is removed from the locator to lift said pin into pushing engagement with the plug.

Claims

1. A bed locator for use with a bed of the type which includes a leg to be removably retained by the locator and which carries electrically powered means having a first electrical connector, said locator comprising:

a second electrical connector electrically connectible to said first connector to connect the electrically actuable means to a source of electric power, and

disconnector means actuated in response to removal of said leg from the locator for disconnecting said first and second connectors.

2. Apparatus according to claim 1, wherein said disconnector means comprising an actuator displaced by said leg as the latter is removed from the locator, and at least one ejector element shifted by said actuator into contact with said first connector to eject the latter from said second connector.

3. Apparatus according to claim 2, wherein said actuator comprises a pivoted treadle having one end positioned to be depressed by said leg as the latter is removed from the locator, and another end which is raised when said one end is depressed, to force said ejector element upwardly against said first connector.

4. Apparatus according to claim 3, wherein said at least one ejector element comprises a plurality of pins seated on said other end of said treadle and liftable by the latter.

5. Apparatus according to claim 1, wherein said locator further includes a cover which automatically closes over the second electrical connector when said first and second connectors are disconnected.

6. Apparatus according to claim 1, wherein said first electrical connector comprises a plug having a flexible boot disposed therearound, said second electrical connector comprising a socket, said boot being configured to snap onto said locator when said plug is connected to said socket to provide a seal around the electrical connection.

7. Apparatus according to claim 6, wherein said boot includes an internal annular recess and said locator includes an annular lip, said lip being received in said recess when said plug is inserted into said socket.

8. A floor-mounted bed locator for use with a hospital bed of the type which includes a leg castor to be removably retained within the locator, and which carries electrically powered means having an electric plug, said locator comprising:

an electrical socket for receiving the plug, and

disconnector means for ejecting the plug from said socket when the castor is removed from said locator and comprising;

at least one ejector pin disposed beneath the plug when the latter is connected to said socket, and

a movably mounted treadle engageable and moved by the castor as the latter is removed from the locator to lift said pin into pushing engagement with the plug.

9. Apparatus according to claim 8, wherein said at least one pin comprises a plurality of pins freely vertically slidable in said locator adjacent said socket, and disposed over a rear end of said treadle, said treadle being pivotably mounted intermediate its front and rear ends, said front end arranged such that the castor rides therealong during travel onto or from said locator.

10. Apparatus according to claim 8, wherein said locator further comprises a cover which automatically closes over said socket upon disconnection of said plug and socket.

11. Apparatus according to claim 8, wherein said plug includes a flexible boot configured to attach onto said locator to form a seal around the electrical connection.

12. Apparatus according to claim 11, wherein said boot includes an internal annular recess, said locator including a lip disposed around said socket, said lip being received in said recess to define said seal.

13. A bed locator for use with a hospital bed of the type which includes a leg castor to be removably retained by the locator and which carries electrically actuable means having an electric cord and plug, said locator comprising:

a housing including at one end a ramp upon which the bed castor rides, and carrying a vertically oriented electrical socket at another end for receiving the plug,

a treadle pivoted intermediate its ends to said frame and including a first end positioned adjacent said ramp and defining a continuation thereof, and a second end,

a plurality of ejector pins vertically slidable in said housing adjacent said socket and arranged to lie beneath the plug when the latter is in connection with said socket, said pins disposed over said second end of said treadle and normally seated thereon so as to be raised thereby into pushing contact with said plug when the bed castor rides upon said first end of said treadle, to push said plug from said socket, and

a cover connected to said housing to automatically close over said socket upon disconnection of said plug and socket.
