Abstract

A V-band clamp includes first and second clamp sections each having an arcuate shape with a first end, a second end, and inside surface defining a recessed channel. A hinge pivotably connects the second end of the first clamp section to the first end of the second clamp section. At least one fastener is configured to releasably connect the first end of the first clamp section to the second end of the second clamp section in a closed position. When the V-band clamp is in the closed position, each fastener extends through an opening in an end face on the first end of the first clamp section and into a bore in an end face on the second end of the second clamp section.

First claim

What is claimed is:

1. A V-band clamp comprising:
a first clamp section and a second clamp section, the first and second clamp sections each having an arcuate shape with a first end and a second end, and having an inside surface defining a recessed channel;
a hinge pivotably connecting the second end of the first clamp section to the first end of the second clamp section; and
at least one fastener configured to releasably connect the first end of the first clamp section to the second end of the second clamp section in a closed position, wherein when in the closed position the at least one fastener extends through an opening in an end face on the first end of the first clamp section and into a bore in an end face on the second end of the second clamp section;
wherein the hinge includes hinge plates extending in a circumferential direction between and connecting the first and second clamp sections, each hinge plate connected to the second end of the first clamp section and to the first end of the second clamp section, and each hinge plate being substantially flush with side faces of the first and second clamp sections; and
wherein a first end of each hinge plate is fixedly secured to one of the first clamp section or the second clamp section, and wherein a second end of each hinge plate is pivotably secured to the other of the first clamp section or the second clamp section.

2. The V-band clamp of claim 1 , wherein the at least one fastener includes a threaded end portion and wherein the bore in the end face on the second end of the second clamp section is a threaded bore configured to engage the threaded end portion of the at least one fastener.

3. The V-band clamp of claim 1 , wherein each hinge plate is substantially flush with side faces, inside faces, and outside faces of the first and second clamp section.

4. The V-band clamp of claim 1 , wherein each at least one fastener is captive to the first clamp section.

5. The V-band clamp of claim 4 , wherein each at least one fastener is partially retained in a pocket hole in the first clamp section.

6. The V-band clamp of claim 1 , wherein in the closed position, the V-band clamp defines a circumferential gap between the first end of the first clamp section and the second end of the second clamp section.

7. The V-band clamp of claim 1 wherein at least one of the first and second clamp sections defines bores extending in a radial direction, and wherein the bores are threaded bores.

8. A vehicle configured for underwater travel, the vehicle comprising:
a first vehicle section;
a second vehicle section abutting the first vehicle section to define a joint; and
the V-band clamp of claim 1 in the closed position around the joint between the first vehicle section and the second vehicle section.

9. An underwater vehicle comprising:
a first vehicle section with a first outside surface and a first flange on a cylindrical first end, the first flange having a first radially outer face that is recessed with respect to the first outside surface of the first vehicle section;
a second vehicle section with a second outside surface and a second flange on a cylindrical second end, the second flange having a second radially outer face that is recessed with respect to the second outside surface of the second vehicle section; and
a V-band clamp comprising:
a first clamp section and a second clamp section, the first and second clamp sections each having an arcuate shape with a first end and a second end, and having an inside surface defining a recessed channel;
a hinge pivotably connecting the second end of the first clamp section to the first end of the second clamp section; and
at least one fastener configured to releasably connect the first end of the first clamp section to the second end of the second clamp section in a closed position, wherein when in the closed position the at least one fastener extends through an opening in an end face on the first end of the first clamp section and into a bore in an end face on the second end of the second clamp section;
wherein the hinge includes hinge plates extending in a circumferential direction between and connecting the first and second clamp sections, each hinge plate connected to the second end of the first clamp section and to the first end of the second clamp section, and each hinge plate being substantially flush with side faces of the first and second clamp sections; and
wherein a first end of each hinge plate is fixedly secured to one of the first clamp section or the second clamp section, and wherein a second end of each hinge plate is pivotably secured to the other of the first clamp section or the second clamp section;

wherein in an installed condition, an entirety of the V-band clamp is flush with or recessed with respect to the first outside surface and the second outside surface.

10. The underwater vehicle of claim 9 , wherein the V-band clamp defines threaded openings extending radially into at least one of the first clamp section and the second clamp section.

11. The underwater vehicle of claim 9 , wherein in the installed condition, the V-band clamp defines a circumferential gap between the first end of the first clamp section and the second end of the second clamp section.

12. The underwater vehicle of claim 9 , further comprising a fastener extending between and connecting the first end of the first clamp section to the second end of the second clamp section when in the closed configuration.
