Abstract
Abstract A clamp for a bundle of cables has a resilient plastic base (11), a C-shaped resilient arm (12) integrally formed with the surface of the base and having a clamp operating portion (13) projecting outward, a guide portion (21) provided around an escape hole (17) on the base (11) so as to oppose to and meet with a free end (14) of the C-shaped resilient arm, and an engaging portion (23) provided opposite to the guide portion (21) with an inserting groove (22) therebetween and having an inclined surface (24) supported by a thin support wall (26), a claw part (25) connected to the lower end of the inclined surface and a release operating portion (27) projecting outward, the C-shaped resilient arm (12) being provided with a plurality of ratchet-shaped projections (16) in tiers on the outer surface near the free end (14) except both edges (15) thereof, the clamp being adapted for guiding the free end (14) into the inserting groove (22) by the inclined wall (18) of the guide portion (21) and the inclined surface (24) of the engaging portion (23), engaging the claw part (25) of the engaging portion (23) with an appropriate one among the plurality of projections (16) and holding both edges (15) of the free end (14) securely in both forward and backward and right and left directions by the side walls (19) (20) of the guide portion (21).

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
312 words
A clamp for a bundle of cables, comprising: a resilient plastic base; an escape hole formed in said base; a guide portion extending from said base adjacent said escape hole, said guide portion having a first upstanding inclined wall at one side of said escape hole, a pair of second upstanding walls at a side of said escape hole opposite said one side and a pair of upstanding third side walls connecting said first and second walls, whereby said guide portion surrounds said escape hole and defines a portion of an inserting groove leading to said escape hole; an engaging portion fixed to said base, said engaging portion including a support wall connected to said base, a claw connected to said support wall and being positioned between said second walls of said guide portion so as to define the remainder of said support groove, an inclined surface connected to said claw, and a release operating portion projecting from said support wall; a C-shaped resilient arm having a first end integrally formed with said base and a free end constructed so as to be insertable in said inserting groove and said escape hole, said free end including a plurality of ratchet shaped projections formed on a central portion thereof, said projections being mutually spaced along a line connecting said ends of said resilient arm, whereby said inclined wall of said guide portion and said inclined surface of said engaging portion guide said free end of said resilient arm into said inserting groove, whereby engagement of said claw with said projections retains said resilient arm in said escape hole, whereby said second walls of said guide portion abut portions of said free end not including said projections so as to support and secure said free end in said escape hole, and whereby said third walls laterally retain said free end of said resilient arm.
Claim 2
Dependent Claim
312 words
A clamp for a bundle of cables, comprising: a resilient plastic base; an escape hole formed in said base; a guide portion extending from said base adjacent said escape hole, said guide portion having a first upstanding inclined wall at one side of said escape hole, a pair of second upstanding walls at a side of said escape hole opposite said one side and a pair of upstanding third side walls connecting said first and second walls, whereby said guide portion surrounds said escape hole and defines a portion of an inserting groove leading to said escape hole; an engaging portion fixed to said base, said engaging portion including a support wall connected to said base, a claw connected to said support wall and being positioned between said second walls of said guide portion so as to define the remainder of said support groove, an inclined surface connected to said claw, and a release operating portion projecting from said support wall; a C-shaped resilient arm having a first end integrally formed with said base and a free end constructed so as to be insertable in said inserting groove and said escape hole, said free end including a plurality of ratchet shaped projections formed on a central portion thereof, said projections being mutually spaced along a line connecting said ends of said resilient arm, whereby said inclined wall of said guide portion and said inclined surface of said engaging portion guide said free end of said resilient arm into said inserting groove, whereby engagement of said claw with said projections retains said resilient arm in said escape hole, whereby said second walls of said guide portion abut portions of said free end not including said projections so as to support and secure said free end in said escape hole, and whereby said third walls laterally retain said free end of said resilient arm.
Claim 3
Dependent Claim
48 words
The clamp for a bundle of cables according to claim 1 in which a curved auxiliary resilient arm is provided opposite to the inner surface of the C-shaped resilient arm so as to clamp the bundle of cables between said auxiliary resilient arm and the C-shaped resilient arm.
Claim 4
Dependent Claim
45 words
The clamp for a bundle of cables according to claim 1 or 2 in which an adhesive tape is applied to a surface of the base opposite said resilient arm so that the base can be fixed to an even surface by said adhesive tape.
Claim 5
Dependent Claim
73 words
The clamp for a bundle of cables according to claim 1 or 2 in which there is integrally provided on a surface of the base opposite said resilient arm, an arrowhead-shaped resilient connecting portion having a joint plate at the central part and lateral thin joint portions, said resilient connecting portion being adapted for fitting the base to a chassis by pushing said resilient connecting portion into a fitting hole of said chassis.
