Abstract
Abstract A frame for a modular piece of office furniture allows electrical cords of appliances on the top of the furniture to be connected to power through the frame at the closest point possible. Each modular element includes a metallic shaped tube 1 having a horizontal upper face 1b to be fixed to the top 2 of the furniture, a substantially vertical rear face 1a and an ornamental front face 1c. The upper face 1b and the front face 1c are spaced by a slot 3 under the edge of the top. All electrical power leads feeding appliances located on the top are received, guided and concealed in the shaped tube 1. The connection between each of the appliances and its corresponding power lead runs through the slot at the point located closest to the appliances. The modular elements may be assembled as a frame serving the multiple purposes of providing support for the top of the piece of furniture, as well as receiving, guiding, protecting, and concealing all the electrical power leads. Each of the modular elements is assembled with a next modular element through an angle bracket fixed to the rear faces 1a of the shaped tubes 1.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
167 words
A frame for a piece of furniture having a generally horizontal furniture top adapted to receive thereon a number of electrical appliances having respective power lines, the frame comprising: at least one section, each section including a substantially horizontal top face, a substantially vertical rear face and a front face, the top face connected to the rear face and the rear face connected to the front face, the front face extending upward toward the top face to form therebetween a continuous horizontal longitudinal slot for passing the power lines, each section defining an interior channel dimensioned for guiding, protecting and concealing the power lines between the top face, rear face and front face; and at least one leg, connected to the section and extending downward therefrom, which leg provides support for the frame and furniture top, at least one of the legs including a metallic shaped tube which has a leg front face which forms part of a leg channel extending to the bottom of the frame.
Claim 2
Dependent Claim
167 words
A frame for a piece of furniture having a generally horizontal furniture top adapted to receive thereon a number of electrical appliances having respective power lines, the frame comprising: at least one section, each section including a substantially horizontal top face, a substantially vertical rear face and a front face, the top face connected to the rear face and the rear face connected to the front face, the front face extending upward toward the top face to form therebetween a continuous horizontal longitudinal slot for passing the power lines, each section defining an interior channel dimensioned for guiding, protecting and concealing the power lines between the top face, rear face and front face; and at least one leg, connected to the section and extending downward therefrom, which leg provides support for the frame and furniture top, at least one of the legs including a metallic shaped tube which has a leg front face which forms part of a leg channel extending to the bottom of the frame.
Claim 3
Dependent Claim
168 words
The frame of claim 1, wherein: a) the shaped tube includes two planar rear faces connected to each other, each planar rear face having a width substantially the same as a width of the frame section and having at a top part of each planar rear face a cut facing a frame section; b) the leg front face is set back from front edges of the rear faces and is connected to at least one of the two rear faces; and c) the frame further comprises a cover which is connected to at least one of the two planar rear faces or the leg front face, to define the leg channel in front of the leg front face of the shaped tube, the leg channel dimensioned to receive, guide and conceal the lines, the cover also defining at its top part a horizontal channel dimensioned to pass the power lines from one section to a next section, the horizontal channel having end openings in front of the cuts.
Claim 4
Dependent Claim
47 words
The frame of claim 1, further comprising: a bracket affixed to the rear face of the section; and a diagonal bolt connected to the leg and to the bracket, and fixing the leg to the bracket so as to provide stiffness to the assembled leg and section.
Claim 5
Dependent Claim
15 words
The frame of claim 1, wherein: each leg comprises a single sheet of shaped material.
Claim 6
Dependent Claim
15 words
The frame of claim 1, wherein: each leg includes an assembly of two shaped tubes.
Claim 7
Dependent Claim
138 words
A frame for a piece of furniture having a generally horizontal furniture top adapted to receive thereon a number of electrical appliances having respective power lines, the frame comprising: at least one section, each section including a substantially horizontal top face, a substantially vertical rear face and a front face, the top face connected to the rear face and the rear face connected to the front face, the front face extending upward toward the top face to rom therebetween a continuous horizontal longitudinal slot for passing the power lines, each section defining an interior channel dimensioned for guiding, protecting and concealing the power lines between the top face, rear face and front face; and a lip positioned with respect to the top face to yieldingly conceal the slot while allowing passage of the power lines through the slot.
