Abstract
Bellow of a flexible material for protecting a coupling comprising first and second connector end subject to vibration and torsion. The bellow comprises a material able to prevent material from entering or exiting the space between the connector ends. The bellow is arranged to be attached to the first connector end by a first clamp and to the second connector end by a second clamp. The bellow is provided with a zipper comprising a zipper slider and first and second zipper part attached to opposite ends of the sheet. Thus, the bellow can be wrapped around said first connector end and second connector end and closed by zipper.
Claims14
A bellow connection for protecting space between a first connector end of a first connector and a second connector end of a second connector in a coupling, the first and second connectors being subjected to relative translation and vibration during use, said bellow connection comprising:
- a bellow formed from a flexible material that is at least partially dustproof or fluidproof and being arranged to be attached to the first connector end by a first clamp and to the second connector end by a second clamp, the bellow being split and comprising at least one sheet defining a plane when flat provided with a zipper comprising a zipper slider and first and second cooperative zipper parts attached to opposite ends of the sheet, the zipper being arranged to close or open the bellow when wrapped around said first and second connector ends;
- a first connector annular sealing formed from a flexible material arranged to be applied on said first end and a second connector annular sealing formed from a flexible material is arranged to be applied on said second connector end, the first and second connector annular sealings being positioned underneath the bellow when the bellow is wrapped around said first connector end and second connector end, wherein
- the bellow sheet exhibits excessive material providing a bellow length measured along a longitudinal axis of the bellow when assembled, the bellow length being longer than a distance between said first and second connector ends, thereby providing first and second regions of the bellow ends without the zipper,
- the first region of the bellows ends overlying the first connector annular sealing with the first clamp being positioned to surround the first connector annular sealing;
- and
- the second region of the bellows ends overlying the second connector annular sealing with the second clamp being positioned to surround the second connector annular sealing.
A bellow connection for protecting space between a first connector end of a first connector and a second connector end of a second connector in a coupling, the first and second connectors being subjected to relative translation and vibration during use, said bellow connection comprising:
- a split bellow formed from a flexible material that is at least partially dustproof or fluidproof and being arranged to be attached to the first connector end by a first clamp and to the second connector end by a second clamp;
- a zipper having zipper parts attached to opposite ends of the split bellow, the zipper being arranged to close or open the split bellow when wrapped around said first and second connector ends;
- a first connector annular sealing formed from a flexible material arranged to be applied on said first end and a second connector annular sealing formed from a flexible material is arranged to be applied on said second connector end, the first and second connector annular sealings being positioned underneath the split bellow when the split bellow is wrapped around said first connector end and second connector end;
- the split bellow having first and second longitudinal end regions without the zipper parts and having abutting edges that do not overlap,
- the first longitudinal end region overlying the first connector annular sealing with the first clamp being positioned to surround the first connector annular sealing;
- and
- the second longitudinal end region overlying the second connector annular sealing with the second clamp being positioned to surround the second connector annular sealing.
A bellow connection for protecting space between a first connector end of a first connector and a second connector end of a second connector in a coupling, the first and second connectors being subjected to relative translation and vibration during use, said bellow connection comprising:
- a split bellow formed from a flexible material that is at least partially dustproof or fluidproof and being arranged to be attached to the first connector end by a first clamp and to the second connector end by a second clamp;
- a zipper having zipper parts attached to opposite ends of the split bellow, the zipper being arranged to close or open the split bellow when wrapped around said first and second connector ends;
- a first connector annular sealing formed from a flexible material arranged to be applied on said first end and a second connector annular sealing formed from a flexible material is arranged to be applied on said second connector end, the first and second connector annular sealings being positioned underneath the split bellow when the split bellow is wrapped around said first connector end and second connector end;
- and
- first and second zipper supports located beneath respective first and second longitudinal end regions of the split bellows.
