摘要： A clamp structure with a clamping band, with a lever-type band tightening closure mechanism including a relatively fixed part and a lever part relatively movable with respect to said relatively fixed part, whereby the relatively fixed part has a base portion and two side walls integral with and extending upwardly from the base portion; the base portion is provided with two slots extending transversely to the longitudinal direction of the clamping band and the lever part has two mutually oppositely and outwardly directed pivot members which are adapted to pivotally engage in corresponding pivot openings in the side walls; one end section of the clamping band includes tolerance-compensating undulations which are covered from below by the remaining underlying end portion of the clamping band; locking projections are provided on the mutually facing surfaces of the side walls to prevent inadvertent reopening.

摘要： A clamp structure with a clamping band whose ends are drawn together by a screw-type tightening mechanism that includes a first band tightening member secured near one band end, a second band tightening member secured near the other band end and a screw member for drawing together the first and second tightening members; one of the band tightening members is of at least semi-circular shape and is retained in a loop-like pocket formed by an end portion of the clamping band externally bent back upon itself and secured to the underlying band portion while the other tightening member also of at least semi-cylindrical shape is retained in a loop-like pocket formed by a separate clamping band part whereby the two loop-like pockets are spaced from one another defining a gap; a stepless internal configuration of the clamping surfaces of the clamping band is assured by a tongue-like extension at the inner band portion adapted to engage in a channel-like indentation provided in the outer clamping band portion; to reliably prevent the inner band portion from bulging out into the gap underneath the screw-type tightening mechanism, a separate reinforcing part is provided underneath the gap which on both sides of the gap extends between the inner and outer band portions; the reinforcing part simultaneously performs a guide function to keep the inner and outer band portions aligned in the axial direction.

摘要： A clamp structure which is provided with at least one pair of plastically deformable ear-like folds located on opposite sides of a center longitudinal cut in the clamping band and spaced in the circumferential direction by such a distance that they can be plastically deformed simultaneously by the use of a pincer-like tool. The pincer-like tool includes two sets of jaw-like members spaced from one another so as to permit simultaneous engagement of the two ear-like folds of a respective pair. The pincer-like tool may thereby have a relatively fixed center member forming a relatively fixed jaw-like member and two pivotally supported jaw-like members operable to be actuated toward one another. In the alternative, the pincer-like tool may include two sets of jaw-like members pivotally connected with each other whose points of pivotal connection are coupled with each other as also corresponding jaw-like members to assure movement in unison. By simultaneously plastically deforming the two ear-like folds while maintaining their relative position in the circumferential direction, a clamp structure can be realized devoid of any gaps, discontinuities or steps that might otherwise be a source of leakage.

摘要： A self-retightening screw-type clamp with predetermined adjusting range for a given clamp size, attained by a predetermined number of apertures provided in the inner band portion of a separate band part in conjunction with a sleeve member of predetermined length interposed between the retightening spring and a part-cylindrical tightening member. The full adjusting range of the screw member is made possible by deforming the threads near its free end. Additionally, to facilitate assembly, the inner band portion of the separate band part is provided with a tongue-like extension which is adapted to engage with a latching device formed in the clamping band so as to hold the tongue-like extension of the inner band portion of the separate clamping band part at least close to the outer surface of the clamping band.

摘要： A method and apparatus for preforming a substantially flat blank of an open clamp adapted to be mechanically interconnected near the free ends thereof into a circular clamp having a configuration at least approximately the configuration of the clamp when installed about an object to be fastened onto a relatively fixed, generally circular part; as the flat blank is being fed through the machine, it is preformed into a generally circular shape with the free ends thereof axially spaced from one another; the pair of rollers feeding the blank may also be so shaped in their external contours that the lateral edges of the blank are bent out in the generally radial direction; additionally the blank is automatically stopped after an initial short feed through the machine to permit stamping of a predetermined part of the flat blank; the entire operation which is preferably pneumatically controlled is thereby automatically cyclically operated as soon as a flat blank is inserted into the machine a predetermined distance.

摘要： A clamp structure with a clamping band having open ends and a mechanical interconnection of the open ends of the band that include at least two outwardly extending hooks in the inner band portion adapted to engage in apertures in the outer band portion; at least one of the hooks is a cold-deformed support hook and another one of the hooks is a generally circumferentially extending combined guide and support hook which has an inclined guide and support surface operable to initially engage with the corresponding aperture in the outer band portion so as to guide the inner and outer band portions toward one another while at the same time absorbing circumferentially directed tightening forces until the cold-deformed support hook becomes effective in also absorbing tightening forces by engagement of its abutment surface with the corresponding aperture.
