US 4,413,868 A · Retractable receptacle support mechanism

Abstract

A retractable basket carrier with chain and sprocket mechanism or travel bar mechanism. A mechanism is provided in the alcove of a desk or similar space in a cabinet to move a carrier from an inner hidden position to an extended position which accesses a wastepaper basket or similar item carried by or depending from the carrier. The mechanism may be installed on either side of the opening in the desk for left or right hand operation and is easily placed in position in the desk with a mounting bracket. An actuator mechanism is installed at the front of the desk for extending the carrier by swing arm movement and to provide a stop for the rearward movement of the carrier. Either a ball chain mechanism or a travel arm with hubs is used to move the carrier. A wastebasket or other item may be supported from the carrier by a universal joint and is moved between the extended and inward positions with only a slight amount of force upon the actuating mechanism. The orientation of the container remains constant relative to the desk throughout the rotation of the support arm connected to the carrier.

Dependent claims

A device for moving a receptacle into and out of a housing, said device comprising:

means for mounting the device to the housing;
a receptacle support;
a carrier arm rotatably connected at one end to said housing and rotatably connected at the other end to said support;
an actuator rod connected to said arm and movable into and out of said housing so as to rotate said arm about said one end;
means connected to said support for maintaining the orientation of said support relative to the housing at all rotational positions of said arm;
whereby a receptacle may be moved into and out of said housing while being maintained in the same orieintation relative to the housing regardless of the position of said arm;
and
wherein said maintaining means comprises a first sprocket affixed to said housing and connected to said one end of said arm so that said arm is rotatable in said first sprocket;
a second sprocket connected to the other end of said arm and affixed to said support so that said second sprocket and said support affixed thereto are rotatable about said other end;
and
a chain mounted on and indexing on said sprockets, whereby said chain plays onto and off from the sprockets with movement of the actuator rod thereby maintaining the orientation of the receptacle.
