Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
131 words
A hose connection for securely clamping a hose onto a nipple to prevent relative axial movement therebetween at high pressures, characterized by a nipple of generally substantially cylindrical configuration having a longitudinal axis, sleeve means positioned on the nipple and having several axially extending finger portions substantially surrounding the circumference of the hose while leaving therebetween only relatively narrow axial slots, and substantially radially contractable clamp means mounted over said finger portions for securely clamping said hose onto said nipple by way of said finger portions, said clamp means having fold means for compensating automatically for changes in the outside diameter of the hose and assuring a substantially constant pressure force holding the hose onto the nipple, and said finger portions extending substantially parallel to the longitudinal axis of the nipple.
Claim 2
Dependent Claim
131 words
A hose connection for securely clamping a hose onto a nipple to prevent relative axial movement therebetween at high pressures, characterized by a nipple of generally substantially cylindrical configuration having a longitudinal axis, sleeve means positioned on the nipple and having several axially extending finger portions substantially surrounding the circumference of the hose while leaving therebetween only relatively narrow axial slots, and substantially radially contractable clamp means mounted over said finger portions for securely clamping said hose onto said nipple by way of said finger portions, said clamp means having fold means for compensating automatically for changes in the outside diameter of the hose and assuring a substantially constant pressure force holding the hose onto the nipple, and said finger portions extending substantially parallel to the longitudinal axis of the nipple.
Claim 3
Dependent Claim
45 words
A hose connection according to claim 1, wherein said clamp means includes fold means having generally outwardly extending leg portions interconnected by a web portion and adapted to be contracted by application of oppositely directed forces at the radially inner ends of said leg portions.
Claim 4
Dependent Claim
21 words
A clamp according to claim 2, wherein at least two fold means are provided along the circumference of the clamp means.
Claim 5
Dependent Claim
24 words
A hose connection according to claim 3, wherein generally circumferentially extending reinforcing means are provided in the web portion of a respective fold means.
Claim 6
Dependent Claim
61 words
A hose connection in which the nipple has an inner end to be covered by the hose and an outer exposed end according to claim 4, further comprising stop means for limiting axial movement of said hose in the direction toward the outer exposed end of the nipple and for limiting axial movement of said sleeve means in the opposite direction.
Claim 7
Dependent Claim
22 words
A hose connection according to claim 5, wherein said stop means also effectively provides space for the expansion of excess hose material.
Claim 8
Dependent Claim
33 words
A hose connection according to claim 6, wherein said stop means inCludes collar means on said nipple and disc means between said collar means and the disclike bottom portion of said sleeve means.
Claim 9
Dependent Claim
61 words
A hose connection in which the nipple has an inner end to be covered by the hose and an outer exposed end according to claim 1, further comprising stop means for limiting axial movement of said hose in the direction toward the outer exposed end of the nipple and for limiting axial movement of said sleeve means in the opposite direction.
Claim 10
Dependent Claim
22 words
A hose connection according to claim 8, wherein said stop means also effectively provides space for the expansion of excess hose material.
Claim 11
Dependent Claim
68 words
A hose connection according to claim 9, wherein said sleeve means includes a disclike bottom portion, and said stop means includes collar means on said nipple and disc means separated from said nipple and said sleeve means and between said collar means and the disclike bottom portion of said sleeve means and land means on said nipple between the collar means and the inner end of said nipple.
Claim 12
Dependent Claim
25 words
A hose connection according to claim 8, wherein said stop means provides space for the expansion of excess hose material substantially in the axial direction.
Claim 13
Dependent Claim
52 words
A hose connection according to claim 8, wherein said sleeve means includes a disclike bottom portion, and said stop means includes collar means on said nipple and disc means separate from said nipple and said sleeve means and disposed between said collar means and the disclike bottom portion of said sleeve means.
Claim 14
Dependent Claim
22 words
A hose connection according to claim 1, which includes means to automatically compensate for changes in the volume of the hose material.
Claim 15
Dependent Claim
29 words
A hose connection according to claim 1, wherein the dimension of a finger portion in the circumferential direction is several times that of a slot in the circumferential direction.
Claim 16
Dependent Claim
71 words
A hose connection according to claim 1, wherein the nipple is provided with an enlarged tool-engaging portion at the end opposite the hose-receiving end, said sleeve means including a disclike bottom portion provided with an aperture larger in diameter than the diameter of said nipple, said finger portions extending from said bottom portion, and said bottom portion being disposed on said nipple intermediate its hose-receiving end and said enlarged tool-engaging portion.
Claim 17
Dependent Claim
33 words
A hose connection according to claim 15, wherein said sleeve means essentially consists only of a disclike bottom portion and of said finger portions directly adjoining said bottom portions at substantially right angles.
Claim 18
Dependent Claim
85 words
A hose connection according to claim 1, wherein said clamp means has circumferential surface portions in clamping engagement with said finger portions, which extend substantially parallel to the longitudinal axis of the nipple and have a dimension in the axial direction that is considerably shorter than the axial length of the nipple, said circumferential surface portions being in clamping engagement with said finger portions substantially over their entire axial dimension so that said finger portions are radially compressed over the extent of said axial dimension.
Claim 19
Dependent Claim
55 words
A hose connection according to claim 1, wherein said sleeve means essentially consists only of a disclike bottom portion and of said finger portions directly adjoining said bottom portion at substantially right angles, the dimensions of each finger portion in the circumferential direction being a multiple the width of a slot in the circumferential direction.
