Abstract

Interlocking bend limiter sections are substantially mirror images of each other and are joined to form an interlocking bend limiter segment without use of fasteners by engaging engaging each other's interlocking ends. An interlocking bend limiter comprises a plurality of interlocking bend limiter segment secured at an end by an end piece.

Claims (45)

1. An interlocking bend limiter segment, comprising:

a. a first semi-tubular section, the first semi-tubular section further comprising:

i. a substantially spherical first end, the substantially spherical first end further comprising:

1. an engaging section disposed about an outer surface of the substantially spherical first end; and

2. a portion of a conduit therethrough;

ii. a substantially semi-circular second end, the substantially semi-circular second end further comprising:

1. an engaging section receiver dimensioned and adapted to engage the engaging section of the substantially spherical first end, the engaging section receiver defining a further portion of the conduit therethrough;

2. an interlock, comprising:

a. an interlock tab; and

b. a corresponding interlock tab receiver; and

iii. a substantially semi-tubular middle section disposed intermediate the substantially spherical first end and the substantially semi-circular second end, the substantially semi-tubular middle section defining a further portion of the conduit therethrough; and

b. a second semi-tubular section, substantially identical to the first semi-tubular section, the first semi-tubular and second semi-tubular sections dimensioned and configured to be joined cooperatively at their respective interlocks, the first semi-tubular section interlock tab receiver dimensioned and adapted to receive the corresponding interlock tab of the second semi-tubular section, the portions of the conduits of the cooperatively joined first semi-tubular and second semi-tubular sections providing an enclosed fluid pathway therethrough.

2. The interlocking bend limiter segment of claim 1 , wherein:

a. the engaging section disposed about the outer surface of the substantially spherical first end of the first semi-tubular section comprises a ridge; and

b. the engaging section receiver of the second semi-tubular section comprises a channel dimensioned and adapted to receive the ridge.

3. The interlocking bend limiter segment of claim 1 , wherein the first and second semi-tubular sections are dimensioned and configured to be joined by their engaging sections without using additional fasteners.

4. The interlocking bend limiter segment of claim 1 , wherein each of the first and second semi-tubular sections further comprises a plurality of alignment guides integral with a separate portion of each respective substantially tubular middle section, one of the alignment guides of the first semi-tubular section being dimensioned and configured to cooperatively receive one of the alignment guides of the second semi-tubular section.

5. The interlocking bend limiter segment of claim 4 , wherein one of the alignment guides comprises a post and a corresponding alignment guide receiver is dimensioned and configured to receive the post.

6. The interlocking bend limiter segment of claim 1 , wherein at least one of the first semi-tubular and second semi-tubular sections comprises a plastic.

7. The interlocking bend limiter segment of claim 1 , wherein at least one of the first semi-tubular and second semi-tubular sections comprises an armored portion.

8. An interlocking bend limiter, comprising:

a. a first segment, comprising:

i. a first semi-tubular section, the first semi-tubular section further comprising:

1. a substantially spherical first end, the substantially spherical first end further comprising:

a. an engaging section disposed about an outer surface of the substantially spherical first end; and

b. a partial portion of a conduit therethrough;

2. a substantially semi-circular second end, the substantially semi-circular second end further comprising:

a. an engaging section receiver dimensioned and adapted to engage the engaging section of the substantially spherical first end, the engaging section receiver defining a further partial portion of the conduit therethrough;

b. an interlock, comprising:

 i. a interlock tab; and

 ii. a corresponding interlock tab receiver; and

3. a substantially semi-tubular middle section disposed intermediate the substantially spherical first end and the substantially semi-circular second end, the substantially semi-tubular middle section defining a further partial portion of the conduit therethrough; and

ii. a second semi-tubular section, substantially identical to the first semi-tubular section, the first semi-tubular and second semi-tubular sections dimensioned and configured to be joined cooperatively at their respective interlocks, the first semi-tubular section interlock tab receiver dimensioned and adapted to receive a corresponding interlock tab of the second semi-tubular section, the partial conduits of the cooperatively joined first semi-tubular and second semi-tubular sections defining an interior fluid pathway therethrough;

b. a second segment, identical to the first segment, the first substantially spherical first end of the first segment cooperatively received into the substantially semi-circular second end of the second segment, thereby locking the first and second semi-tubular sections of the first segment together; and

c. an end piece coupled to the substantially spherical first ends of the second segment at an interlocked exposed end of the second segment, the end piece dimensioned and adapted to lock together the first and second semi-tubular sections of the second segment together.

9. The interlocking bend limiter of claim 8 , wherein assembly of the first and second segments requires no bolts.

10. The interlocking bend limiter of claim 8 , wherein the joined first and second segments are dimensioned and adapted to provide a predetermined amount of movement about at least two axes.

11. A method of providing an interlocking bend limiter, comprising:

a. assembling a first interlocking bend limiter segment by joining a first semi-tubular section to a second semi-tubular section, the first semi-tubular and second semi-tubular sections substantially identical to each other, each semi-tubular section comprising a substantially spherical first end, an interlocking second end and a substantially semi-tubular middle section intermediate the substantially spherical first end and the interlocking second end, the assembling comprising engaging the first semi-tubular section's interlocking second end with the second semi-tubular section's interlocking second end;

b. assembling a second interlocking bend limiter section about the substantially spherical first end of the first interlocking bend limiter section, the second interlocking bend limiter section substantially identical to the first interlocking bend limiter section, the assembling of the second interlocking bend limiter section comprising:

i. positioning an engaging section receiver of the second interlocking bend limiter section about an engaging section of the substantially spherical first end of the first interlocking bend limiter section; and

ii. engaging the first semi-tubular section's interlocking second end with the second semi-tubular section's interlocking second end; and

c. securing an end piece about the substantially spherical first end of the second interlocking bend limiter section, the end piece comprising a lock dimensioned and adapted to lock together the second interlocking bend limiter section.

12. The method of providing an interlocking bend limiter of claim 11 , wherein the end piece is secured about the substantially spherical first end of the second interlocking bend limiter section using a fastener.

13. The method of providing an interlocking bend limiter of claim 12 , wherein the fastener comprises at least one of (i) a bolt or (ii) a clamp.
