Abstract
Abstract A plurality of interengaging sliding, hollow elements of essentially rectangular cross-sectional area are so arranged that the hollow profiles have guide surfaces formed on the outside and the inside, the profiles being additionally formed with interengaging projections and recesses at the horizontal sides of the rectangular profiled elements, so that the weight of clothes being hung on the dryer is accepted by the guide surfaces, and the guide surfaces do not distort. Preferably a pair of parallel arms are provided with rods interengaging the arms, secured to stubs attached to the telescoping interengaging elements, the stubs sliding in open notches formed in adjacent telescoping elements, to form a rigid assembly, which can support the weight of laundry hung thereon, without deformation.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
109 words
Telescoping clothes dryer structure comprising two essentially identical facing telescoping arms (1, 2), each arm including a plurality of interengaging sliding hollow elements (3-8, 1015) having inner and outer sides, respective elements decreasing in size to telescope into each other; a plurality of clothes supporting rods (31), each rod connecting the inner sides of respective elements of the facing arms and securing said elements together into a rigid unit; and slots (32-38) formed at the inner sides of the elements and extending longitudinally of the elements so that the extending rods interconnecting the elements will be accepted in the slots when the elements are slidably telescoped into each other.
Claim 2
Dependent Claim
109 words
Telescoping clothes dryer structure comprising two essentially identical facing telescoping arms (1, 2), each arm including a plurality of interengaging sliding hollow elements (3-8, 1015) having inner and outer sides, respective elements decreasing in size to telescope into each other; a plurality of clothes supporting rods (31), each rod connecting the inner sides of respective elements of the facing arms and securing said elements together into a rigid unit; and slots (32-38) formed at the inner sides of the elements and extending longitudinally of the elements so that the extending rods interconnecting the elements will be accepted in the slots when the elements are slidably telescoped into each other.
Claim 3
Dependent Claim
61 words
Dryer structure according to claim 1 including a bearing stub (17-30) attached to the sides of at least some of the sliding elements (3-9; 10-16) of the arms (1,2); the rods being secured in the stubs; the slots (32-38) formed in the sides of adjacent elements being of sufficient size to accept the stubs when the arms are in telescoped condition.
Claim 4
Dependent Claim
97 words
Dryer structure according to claim 1, wherein the elements have two transverse profiles which are essentially a rectangle having shorter and longer sides with inside and outside surfaces, guide surfaces (40, 41; 42, 43) formed at the shorter sides of the profile and projections (52, 53, 54, 55) and grooves (44, 45, 46, 47) formed at one or more sides of the elements, the inside and outside surfaces of adjacent elements being in engagement and the projections and grooves being in interlocking engagement to provide load bearing surfaces for the telescoping elements upon extension of the arm.
Claim 5
Dependent Claim
19 words
Dryer structure according to claim 3, wherein the projections and grooves are located at longer sides of the elements.
Claim 6
Dependent Claim
36 words
Dryer structure according to claim 4 wherein further guide surfaces are formed at the projections and grooves, said further guide surfaces being essentially parallel to the guide surfaces formed at the shorter sides of the rectangle.
Claim 7
Dependent Claim
59 words
Dryer structure according to claim 1, wherein at least some of the telescoping elements are formed with an elastically springy catch (54), and a groove having a shoulder (55) located in the preceding next large slider, the catch engaging against the shoulder of the preceding slider to prevent removal of the next subsequent slider from within the telescoping arm.
Claim 8
Dependent Claim
152 words
Telescoping clothes dryer structure wherein a pair of essentially identical telescoping arms and cross connecting rods (31) are provided, the rods spacing the arms from each other, each of said telescoping arms comprising a plurality of interengaging sliding, hollow elements (3-8; 10-15) the respective elements decreasing in size to telescope into each other, the elements each having a transverse profile which is essentially a rectangle having shorter and longer sides and having guide surfaces (40, 41; 46, 47) formed at the shorter sides of the rectangle, some of said elements of one of said arms being rigidly interconnected by a rod into a unit with the respective element of the other of said arms, the longer sides of the rectangle forming inner and outer sides, one or more of, said sides being formed with slots extending longitudinally of the arms and of sufficient width to permit the rods to be received therein.
Claim 9
Dependent Claim
152 words
Telescoping clothes dryer structure wherein a pair of essentially identical telescoping arms and cross connecting rods (31) are provided, the rods spacing the arms from each other, each of said telescoping arms comprising a plurality of interengaging sliding, hollow elements (3-8; 10-15) the respective elements decreasing in size to telescope into each other, the elements each having a transverse profile which is essentially a rectangle having shorter and longer sides and having guide surfaces (40, 41; 46, 47) formed at the shorter sides of the rectangle, some of said elements of one of said arms being rigidly interconnected by a rod into a unit with the respective element of the other of said arms, the longer sides of the rectangle forming inner and outer sides, one or more of, said sides being formed with slots extending longitudinally of the arms and of sufficient width to permit the rods to be received therein.
Claim 10
Dependent Claim
63 words
Dryer structure according to claim 1 including a bearing stub (17-30) attached to the inner sides of at least some of the slider elements (3-9; 10-16) of the arms, the slots (32-38) being formed in the inner sides of adjacent elements being of sufficient size to accept the stubs when the arms are in telescoped condItions, the rods being secured in the stubs.
Claim 11
Dependent Claim
20 words
Dryer structure according to claim 7, wherein projections and grooves are located at one or more sides of the elements.
Claim 12
Dependent Claim
39 words
Dryer structure according to claim 9, wherein the projections and grooves are located at the longer sides to provide laterally limiting guide portions for lateral guidance of an inner telescoping element with respect to its preceding outer telescoping element.
