Claim 9

A piece of office furniture comprising a desk top and a support therefor, said support consisting essentially of an upright extensible post including a cylinder member and a piston member slidable in said cylinder member under fluid pressure, one of said members being rigid with said desk top, the other of said members being fixedly secured to a surrounding building structure provided with utility mains, said piston member being hollow and internally provided with at least one supply line joining said mains at an end of said piston member and having terminal means at said desk top for connection to office equipment to be supplied thereby; said supply line including a flexible element emerging from the interior of said piston member at an intermediate point and continuing thence outside said piston and cylinder members with enough slack to allow movement of an edge of said cylinder member past said intermediate point in opposite directions, said cylinder member being spaced from said piston member in the region of said edge with formation of a clearance accommodating part of said element.

Claim 10

A piece of office furniture comprising a desk top and a support therefor, said support consisting essentially of an upright extensible post including a cylinder member and a piston member slidable in said cylinder member under fluid pressure, one of said members being rigid with said desk top, the other of said members being fixedly secured to a surrounding building structure provided with utility mains, said piston member being hollow and internally provided with at least one supply line joining said mains at an end of said piston member and having terminal means at said desk top for connection to office equipment to be supplied thereby; said supply line including a flexible element emerging from the interior of said piston member at an intermediate point and continuing thence outside said piston and cylinder members with enough slack to allow movement of an edge of said cylinder member past said intermediate point in opposite directions, said cylinder member being spaced from said piston member in the region of said edge with formation of a clearance accommodating part of said element.

Claim 11

A piece of furniture as defined in claim 8 wherein said cylinder member is provided with an external sheath spacedly surrounding same and forming therewith a channel for a portion of said element.

Claim 12

A piece of furniture as defined in claim 5 wherein said cylinder member is provided near said edge with a hole traversed by said element between said channel and said clearance.

Claim 13

A piece of office furniture comprising a desk top and a suppoRt therefor, said support consisting essentially of an upright extensible post including a cylinder member and a piston member slidable in said cylinder member under fluid pressure, one of said members being rigid with said desk top, the other of said members being provided with an open-ended socket fixedly secured to a surrounding building structure and being further provided with retaining means for immobilizing same in said socket, said piston member being hollow and internally provided with at least one supply line having terminal means at said desk top for connection to office equipment to be supplied thereby; said supply line including at least one electrical conductor and coupling means comprising an axially movable base plate in said socket resiliently biased toward the open end of said socket receiving said other of said members, the latter having an end plate with a termination for said conductor, said base plate carrying a complementary formation engageable with said termination in a fully inserted position of said other of said members and tied to utility mains in said structure.

Claim 14

A piece of office furniture comprising a desk top and a suppoRt therefor, said support consisting essentially of an upright extensible post including a cylinder member and a piston member slidable in said cylinder member under fluid pressure, one of said members being rigid with said desk top, the other of said members being provided with an open-ended socket fixedly secured to a surrounding building structure and being further provided with retaining means for immobilizing same in said socket, said piston member being hollow and internally provided with at least one supply line having terminal means at said desk top for connection to office equipment to be supplied thereby; said supply line including at least one electrical conductor and coupling means comprising an axially movable base plate in said socket resiliently biased toward the open end of said socket receiving said other of said members, the latter having an end plate with a termination for said conductor, said base plate carrying a complementary formation engageable with said termination in a fully inserted position of said other of said members and tied to utility mains in said structure.

Claim 15

A piece of office furniture comprising a desk top and a support therefor, said support consisting essentially of an upright extensible post including a cylinder member and a hollow piston member slidable in said cylinder member under fluid pressure, one of said members being rigid with said desk top, the other of said members being provided at an end portion thereof with a socket fixedly secured to a surrounding building structure and being further provided with retaining means for immobilizing said end portion in said socket; electrical conductor means within said post passing partly through said piston member and partly through said cylinder member in a generally vertical direction, said conductor means having a first termination at said desk top for connection to office equipment to be supplied thereby and having a second termination at said end portion; and connector means in said socket matingly engaging said second termination upon insertion of said end portion into said socket, said connector means being conductively joined to utility means in said structure.

Claim 16

A piece of office furniture comprising a desk top and a support therefor, said support consisting essentially of an upright extensible post including a cylinder member and a hollow piston member slidable in said cylinder member under fluid pressure, one of said members being rigid with said desk top, the other of said members being provided at an end portion thereof with a socket fixedly secured to a surrounding building structure and being further provided with retaining means for immobilizing said end portion in said socket; electrical conductor means within said post passing partly through said piston member and partly through said cylinder member in a generally vertical direction, said conductor means having a first termination at said desk top for connection to office equipment to be supplied thereby and having a second termination at said end portion; and connector means in said socket matingly engaging said second termination upon insertion of said end portion into said socket, said connector means being conductively joined to utility means in said structure.
