Abstract
Abstract A hose clamp having a preferably, relatively wide strap and a tightening mechanism for tightening the strap is described. An end region of the strap is provided with at least one transverse channel, formed by crimping or bending the strap in this end region. At least one base member, which is part of the housing of the tightening mechanism, engages the transverse channel in a form-fitting manner. The base member is preferably flush with the adjacent interior sides of the strap.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
254 words
A hose clamp comprising, in combination: a. a strap having an end portion thereof formed to define a single, inwardly open transverse channel having interior sides; and b. a tightening mechanism including: i. a housing for parts of said mechanism, said housing having an arched middle portion and outwardly directed shoulders which are angled downwardly, ii. said parts including two base members in engagement with said single, transverse channel in a form-fitting positive tensile manner, said base members being embodied as two angled tops of said housing and having free ends positioned in said single, transverse channel from opposite ends thereof, said two base members being respectively connected to respective lower ends of said shoulder and said housing being free of any fixed connection to said strap, iii. a worm gear carried within said housing and secured against axial displacement therein, said housing having inwardly directed flanges, at its two faces, which serve for axial and radial mounting of said worm gear, threads of said worm gear engaging ribs in said straps, said flanges forming apertures for said worm gear, said apertures being open toward said strap and the distance between the bottom of said transverse channel of said strap and said threads of said worm gear being smaller than the thickness of said strap, and iv. an opening with a narrowing toward its free end of one of said base members and a projection from the said free end of the other of said base members, said projection being inserted into said opening.
Claim 2
Dependent Claim

A hose clamp comprising, in combination: a. a strap having an end portion thereof formed to define a single, inwardly open transverse channel having interior sides; and b. a tightening mechanism including: i. a housing for parts of said mechanism, said housing having an arched middle portion and outwardly directed shoulders which are angled downwardly, ii. said parts including two base members in engagement with said single, transverse channel in a form-fitting positive tensile manner, said base members being embodied as two angled tops of said housing and having free ends positioned in said single, transverse channel from opposite ends thereof, said two base members being respectively connected to respective lower ends of said shoulder and said housing being free of any fixed connection to said strap, iii. a worm gear carried within said housing and secured against axial displacement therein, said housing having inwardly directed flanges, at its two faces, which serve for axial and radial mounting of said worm gear, threads of said worm gear engaging ribs in said straps, said flanges forming apertures for said worm gear, said apertures being open toward said strap and the distance between the bottom of said transverse channel of said strap and said threads of said worm gear being smaller than the thickness of said strap, and iv. an opening with a narrowing toward its free end of one of said base members and a projection from the said free end of the other of said base members, said projection being inserted into said opening.
Claim 3
Dependent Claim
23 words
A hose clamp according to claim 1, wherein said single, transverse channel extends in width substantially over the entire length of said housing.
Claim 4
Dependent Claim
20 words
A hose clamp according to claim 1, wherein said ribs in said strap are formed by apertures in said strap.
Claim 5
Dependent Claim
29 words
A hose clamp according to claim 1, wherein said transverse channel is arched to correspond to the curvature of a particular outer diameter of a hose to be clamped.
Claim 6
Dependent Claim
24 words
A hose clamp according to claim 1, wherein said opening in said one of said base members is progressively narrowed toward its free end.
Claim 7
Dependent Claim
