Hose fixture device
First Claim
1. A hose fixture device for attachment to a hose having a mounting projection thereon, the hose fixture device comprising:
- a first cylindrical wall portion and a second cylindrical wall portion;
a plurality of projections on said first cylindrical wall portion for engaging said mounting projection on said hose to thereby engage said hose to said hose fixture device, said projection projecting from said first cylindrical wall portion in a radial direction and being spaced apart in a circumferential direction of said first cylindrical wall portion such that there is a circumferential gap between adjacent projections in the circumferential direction; and
a plurality of gripping members provided on said second cylindrical wall portion for engaging an end of said hose, said gripping members projecting from said second cylindrical wall portion in a radial direction and being integral with said first cylindrical wall portion and being spaced apart in the circumferential direction so that there is a gap between adjacent gripping members in the circumferential direction.

Abstract
A hose fixture device has a cylindrical wall with projections thereon, which projections engage a corresponding mounting projection of a hose. Normally that mounting projection is a helix, so that there is a screw engagement. The projections are arranged circumferentially around the cylindrical wall with gaps therebetween. There are also gripper members, again spaced circumferentially with gaps therebetween, which grip an end of the hose. The gaps make is easy to see such engagement. The gripper members are aligned with the gaps between those projections. This provides a secure fixing of the hose to the hose fixture device. Furthermore, the device may be moulded easily. Such a hose fixture device may be used to attache a hose joint component (e.g. a suction tool) to a hose of an electric vacuum cleaner.

16. A hose fixture device for attachment to a hose having a mounting projection thereon, the hose fixture device comprising:
-
a first cylindrical wall having mounting means thereon to engage said mounting projection on said hose to attach the hose to the hose fixture; and a plurality of hose engagement means on second wall for engaging said mounting projection on said hose, thereby to engage said hose to said hose fixture device; wherein said hose engagement means is arranged to grip said mounting projection between said hose engagement means with elastic deformation of said hose between said hose engagement means so as to prevent free rotation of said hose and said hose fixture device, forced rotation of said hose and said hose fixture device above a predetermined loading releasing said grip without damage to said hose or said hose fixture device, whereby said hose fixture device is disengagable from said hose.
