Frame structure for bathroom cabinets

Claim 2

A frame structure comprised of two side profiles or components having arms extending at right angles at their lower and upper ends, and an upper and lower profile or component each of which is hollow and has the same section lengthwise, these four components or profiles being joined in an engaging relationship such that the arms of the side profiles extend into the hollow part of the upper and lower profiles at each end respectively to form an enclosure, wherein a wall extends around the longitudinal and lateral periphery of the side profiles and adjacent the interior extent of the protruding arms and is adapted to receive in frictional engagement a reinforcing unit cover to produce a double unit wall, and wherein, further, the said arms are adapted to cooperatively extend into the said hollow parts of said upper and lower profiles and to be frictionally joined thereto.

Claim 3

A frame structure comprised of two plastic side profiles having a plurality of arms separated by spaces and extending at right angles at the lower and upper ends of said side profile, and a plastic upper and lower profile each of which is hollow and has the same section lengthwise, the upper and lower profiles having open ends divided into spaced openings by dividing elements with the spaced openings corresponding to the extended arms of the side profiles and the dividing elements corresponding to the spaces separating the extending arms, the open ends of the upper and lower profile having a recess extending longitudinally along the profile near one edge for receiving the periphery of a back plate, the side profile having a receiving space extending longitudinally along its entire length near one edge for receiving another portion of the periphery of a back plate with the space extending to the underside of the protruding arm and corresponding to the recess in the open ends of the upper and lower profile, a ridge extending adjacent the outer limit of the space in the side profile and longitudinally along its length to give added support to the back plate, and a wall extending perpendicular to the side profile interior surface and continuing around the longitudinal and lateral periphery of the side profile and adjacent to the extending arms and the receiving space and designed to receive in frictional engagement a cover, the two upper and side profiles being joined in angular relationship such that the arms of the side profiles extend into the corresponding spaces in the open ends of the upper and lower profiles and the recess or space extending around the near edge of all profiles slidably and frictionally engaging the periphery of a back plate member to form an enclosure with four walls and a back, said enclosure having substantially solid rectangular back corner sections formed by the frictional engagement of said profiles and said back plate member.

Claim 4

A frame structure comprised of two plastic side profiles having a plurality of arms separated by spaces and extending at right angles at the lower and upper ends of said side profile, and a plastic upper and lower profile each of which is hollow and has the same section lengthwise, the upper and lower profiles having open ends divided into spaced openings by dividing elements with the spaced openings corresponding to the extended arms of the side profiles and the dividing elements corresponding to the spaces separating the extending arms, the open ends of the upper and lower profile having a recess extending longitudinally along the profile near one edge for receiving the periphery of a back plate, the side profile having a receiving space extending longitudinally along its entire length near one edge for receiving another portion of the periphery of a back plate with the space extending to the underside of the protruding arm and corresponding to the recess in the open ends of the upper and lower profile, a ridge extending adjacent the outer limit of the space in the side profile and longitudinally along its length to give added support to the back plate, and a wall extending perpendicular to the side profile interior surface and continuing around the longitudinal and lateral periphery of the side profile and adjacent to the extending arms and the receiving space and designed to receive in frictional engagement a cover, the two upper and side profiles being joined in angular relationship such that the arms of the side profiles extend into the corresponding spaces in the open ends of the upper and lower profiles and the recess or space extending around the near edge of all profiles slidably and frictionally engaging the periphery of a back plate member to form an enclosure with four walls and a back, said enclosure having substantially solid rectangular back corner sections formed by the frictional engagement of said profiles and said back plate member.

Claim 5

The frame structure according to claim 2 wherein the enclosure is divided into compartments by horizontal and vertical divider units, and the farthest longitudinal edge of the arm protruding from the side profile on the portion of the profile opposite the recess extends beyond the lateral boundary of the side profile a sufficient distance to permit affixing a door to the base of the arm.
