Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
88 words
A cord holder comprising in combination: a rigid annular member provided with means adapted to be attached to the casing of an electric appliance; a deformable insulation hollow member tightly fitted in said annular member and at one end having a stepped taper configuration portion; said stepped taper configuration portion including a plurality of sections having different inner diameters for selectively receiving and holding therein electric cords having different diameter ranges; and said plurality of sections being provided with integral tightening pieces surrounding them and receiving tightening bolts.
Claim 2
Dependent Claim
88 words
A cord holder comprising in combination: a rigid annular member provided with means adapted to be attached to the casing of an electric appliance; a deformable insulation hollow member tightly fitted in said annular member and at one end having a stepped taper configuration portion; said stepped taper configuration portion including a plurality of sections having different inner diameters for selectively receiving and holding therein electric cords having different diameter ranges; and said plurality of sections being provided with integral tightening pieces surrounding them and receiving tightening bolts.
Claim 3
Dependent Claim
41 words
A cord holder as set forth in claim 1, in which said means adapted to be attached to the casing of said electric appliance comprises threads provided on the outer periphery of said annular member at one end of the latter.
Claim 4
Dependent Claim
91 words
A cord holder as set forth in claim 1, in which said deformable insulation hollow member has a tubular configuration and is further provided with an integral abutment at one end adapted to abut against the adjacent end of said annular member, an integral flanged portion positioned between the opposite ends of the hollow member, and an integral frustoconical portion continuous to said flanged portion at the end of the flanged portion remote from said abutment, said abutment and flanged portion defining an annular recess therebetween for receiving said annular member.
Claim 5
Dependent Claim
93 words
A cord holder as set forth in claim 3, in which said stepped taper configuration portion of the deformable insulation hollow member is continuous to said frustoconical portion at the end of the frustoconical remote from said flanged portion and gradually reduces its diameter from the end of the frustoconical portion remote from the flanged portion toward said one end of the deformable insulation hollow member with the section adjacent to said frustoconical portion having the largest diameter and the section at said one end of the hollow member having the smallest diameter.
Claim 6
Dependent Claim
40 words
A cord holder as set forth in claim 1, in which each of said sections of the stepped taper configuration portion has substantially a U-shaped tightening piece including two opposite legs provided with aligned bores for receiving said tightening bolts.
Claim 7
Dependent Claim
46 words
A cord holder as set forth in claim 1, in which said stepped taper configuration portion of the deformable hollow member is so arranged that the largest diameter section is positioned at the innermost end, and the smallest diameter section is positioned at the outermost end.
Claim 8
Dependent Claim
41 words
A cord holder as set forth in claim 3, in which said means adapted to be attached to the casing of said electric appliance compriseS threads provided on the outer periphery of said annular member at one end of the latter.
Claim 9
Dependent Claim
93 words
A cord holder as set forth in claim 7, in which said stepped taper configuration portion of the deformable insulation hollow member is continuous to said frustoconical portion at the end of the frustoconical remote from said flanged portion and gradually reduces its diameter from the end of the frustoconical portion remote from the flanged portion toward said one end of the deformable insulation hollow member with the section adjacent to said frustoconical portion having the largest diameter and the section at said one end of the hollow member having the smallest diameter.
Claim 10
Dependent Claim
40 words
A cord holder as set forth in claim 2, in which each of said sections of the stepped taper configuration portion has substantially a U-shaped tightening piece including two opposite legs provided with aligned bores for receiving said tightening bolts.
Claim 11
Dependent Claim
46 words
A cord holder as set forth in claim 2, in which said stepped taper configuration portion of the deformable hollow member is so arranged that the largest diameter section is positioned at the innermost end, and the smallest diameter section is positioned at the outermost end.
