Abstract
Abstract An electric wire bundle clamp having a mounting base, an elastic curved member provided on the mounting base so as to be integral at one end thereof with the mounting base and open at the other end, and a retaining portion formed on the mounting base for retaining the open end of the elastic curved member, in which the open end of the elastic curved member is bent outwards elastically deformably to form a bent portion with a stepped retaining projection formed in the vicinity thereof and a part of the bent end portion is used as a clamp operating piece, while on the mounting base are provided at least two projections which are spaced from each other so that the bent portion of the open end of the elastic curved member can be inserted therebetween, and on the inner surface of an outside one of the projections on the mounting base is formed a retaining projection capable of engaging the above retaining projection formed in the vicinity of the bent portion. Because of such a construction, it is possible to easily perform clamping and unclamping operations, and the electric wire bundle once clamped is held firmly in the clamped state and is seldom unclamped. Besides, there is given a large tolerance of the maximum clamping diameter which permits a positive and elastic clamping regardless of a slight increase or decrease in the diameter of the electric wire bundle to be clamped. Further, the wire bundle clamp of the above construction is easy to handle even in a narrow space.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
200 words
An electric wire bundle clamp comprising: a mounting base; an elastic member having one end extending from a surface of said base; a substantially V-shaped bent portion having two substantially parallel legs and defining another end of said elastic member, one said leg of said V-shape forming an extension of the length of said elastic member, the other said leg of said V-shape having a first retaining projection extending therefrom; a clamp operating piece extending from said other leg of said V-shape; first and second projecting portions extending from said surface of said base, said first and second projecting portions being mutually spaced by a distance sufficient that said V-shaped bent portion can be inserted therebetween; and a second retaining projection extending from said first projection portion at a position such that said first and second retaining projections may engage one another when said V-shaped bent portion is inserted between said first and second projecting portions, wherein said clamp operating piece is mounted on said V-shaped bent portion such that said first and second projecting portions are released upon the application of pressure on said clamp operating piece in an opening direction away from a base of said bent portion.
Claim 2
Dependent Claim
200 words
An electric wire bundle clamp comprising: a mounting base; an elastic member having one end extending from a surface of said base; a substantially V-shaped bent portion having two substantially parallel legs and defining another end of said elastic member, one said leg of said V-shape forming an extension of the length of said elastic member, the other said leg of said V-shape having a first retaining projection extending therefrom; a clamp operating piece extending from said other leg of said V-shape; first and second projecting portions extending from said surface of said base, said first and second projecting portions being mutually spaced by a distance sufficient that said V-shaped bent portion can be inserted therebetween; and a second retaining projection extending from said first projection portion at a position such that said first and second retaining projections may engage one another when said V-shaped bent portion is inserted between said first and second projecting portions, wherein said clamp operating piece is mounted on said V-shaped bent portion such that said first and second projecting portions are released upon the application of pressure on said clamp operating piece in an opening direction away from a base of said bent portion.
Claim 3
Dependent Claim
35 words
The clamp of claim 1 wherein said elastic member is elongate, the length of said elastic member being formed with at least one small diameter arcuate portion defining at least one protrusion of said length.
Claim 4
Dependent Claim
42 words
The clamp of claim 1 wherein said elastic member is elongate with a curved length, said curved length being further curved in at least one small diameter arcuate portion therealong, so as to define at least one elastic protrusion of said length.
Claim 5
Dependent Claim
14 words
The clamp of claim 3 including a plurality of said small diameter arcuate portions.
Claim 6
Dependent Claim
10 words
The clamp of claim 4 wherein said base is rectangular.
Claim 7
Dependent Claim
50 words
The clamp of claim 1 including at least one finger hold portion projecting from said elastic member at a position adjacent said clamp operating piece and such that said clamp operating piece is moved in said opening direction when said clamp operating piece is moved toward said finger hold portion.
Claim 8
Dependent Claim
26 words
The clamp of claim 1 wherein said first and second projecting portions are mutually parallel and wherein said first and second retaining projections are mutually parallel.
Claim 9
Dependent Claim
37 words
The clamp of claim 7 wherein said second projecting portion is formed lower than said first projecting portion, whereby said first retaining projection can be inserted from the top part of said second projecting portion and locked.
Claim 10
Dependent Claim
13 words
The clamp of claim 5 wherein said elastic protrusions curve toward said base.
Claim 11
Dependent Claim
23 words
The clamp of claim 1 wherein said legs of said V-shape bent portion are more than half as long as said projecting portions.
Claim 12
Dependent Claim
18 words
The clamp of claim 1 including a reinforcing projection extending between said base and said second projecting portion.
Claim 13
Dependent Claim
41 words
The clamp of claim 1 including an upper lateral shift preventing wall connecting said first and second projecting portions at one side thereof and a lower lateral shift preventing wall connecting said first and second projecting portions at another side thereof.
Claim 14
Dependent Claim
26 words
The clamp of claim 1 wherein said clamp operating piece terminates in a clamp operating rod having a width greater than that of said elastic member.
Claim 15
Dependent Claim
16 words
The clamp of claim 13 including a handle at one side of said clamp operating rod.
Claim 16
Dependent Claim
11 words
The clamp of claim 1 wherein said elastic member is flat.
Claim 17
Dependent Claim
92 words
An electric wire bundle clamp comprising: a mounting base; an elastic member having one end extending from a surface of said base; and means for releasably securing another end of said elastic member relative to said base; wherein said elastic member is elongate with a curved length, portions of said curved length being further curved at small diameter arcuate portions so as to define a plurality of elastic protrusions along said length, whereby stresses on said elastic member will cause distortions of said arcuate portions and a change in said curved length.
Claim 18
