摘要： An open clamp structure in which overlapping band portions are mechanically connected by a spring separate from the clamping band; the spring is thereby of low profile having a top portion and lateral portions passing over into mutually facing end portions which are provided with tongue-like extensions adapted to engage in tunnel-shaped embossments in corresponding parts of the clamping band. Means for limiting the extent of stretching to which the spring can be subjected and also providing at the same time a guide function to keep overlapping band portions mutually aligned includes either two tab-like members extending in the longitudinal direction within two narrow slot-like openings only slightly wider than the thickness of the clamping band and of predetermined length or a tunnel-shaped embossment in the inner band portion extending in an elongated opening of only slightly larger width than the embossment to provide the guide function.

摘要： An open clamp structure capable of withstanding very high tightening forces, with a clamping band whose overlapping inner and outer band portions are mechanically locked by a mechanical interconnection including outwardly extending hooks near the free end of the inner band portion adapted to engage with apertures near the free end of the outer band portion; for purposes of tightening the clamp structure upon engagement of at least one hook in the corresponding aperture, a deformable ear with two generally outwardly extending leg portions interconnected by a bridging portion is provided, whereby the bridging portion includes reinforcing means; at least one of the hooks is thereby a cold-deformed hook having force-engaging surface means while another hook is a combined guide and support hook having inclined guide and support surface means formed by its rear edge facing away from the free end of the inner band portion; the reinforcing means is in the form of a generally pan-shaped depression extending over a substantial part of the length and width of the bridging portion.

摘要： A reinforced ear structure for use in a clamp whose clamping band is intended to be contracted by relatively large tightening forces; the ear consists of two outwardly extending leg portions and a reinforced bridging portion interconnecting the leg portions; the bridging portion is provided with a generally pan-shaped, relatively hollow, depressed reinforcement formed by a bottom portion and connecting portions between the bottom portion and the remaining non-depressed bridging portion; the connecting portions thereby extend over substantial parts of the length and width of the bridging portion and the bottom portion is relatively flat.

摘要： A self-tightening lamp formed from spring steel band material which exerts clamping forces by the inherent springiness of the band material. To minimize outwardly projecting parts with their injury danger and to obtain an inner clamping surface substantially devoid of any gaps or steps, the end of the outer band end portion is provided with an elongated slot adapted to receive the tongue-like overlapped inner band end portion. Temporary locking of the clamp is realized by a detent member in the tongue-like inner band end portion adapted to be lockingly engaged by a locking surface in the outer band portion. The elongated slot is thereby of such width as to accommodate the tongue-like inner band portion whereby the detent member is located in the elongated slot when the clamp is in its clamping position.

摘要： In a connection of two edges of areal parts which extend at least along one common section essentially parallel to one another, at least one retaining element is arranged at the one edge which form-lockingly engages from behind, as viewed in the edge direction, in a recess in the other edge. At least one projection arranged laterally offset at the one edge in relation to the retaining element in the direction of the engagement from behind, abuts form-lockingly at the part with the recess essentially in the edge direction. To reliably secure together the parts, laser beam welding is used along the common sections of at least one of the retaining element and of the projection.

摘要： A clamp structure with one or several plastically deformable ears whose holding ability is increased by an external strengthening member surrounding the plastically deformable ear in its non-deformed condition; the lateral portions of the strengthening member are thereby so constructed and shaped that an application of a force to the lateral members will cause the ear to be plastically deformed.

摘要： A clamp structure especially for use in applications in which space conditions do not permit any projecting parts such as plastically deformable ears, and in which outwardly extending hooks adapted to engage in apertures are used to mechanically interconnect the clamp structure; to enable tightening of the band about an object to the fastened, cold-deformed pressed-out embossments are provided in inner and outer band portions, which extend generally in the circumferential direction so that each pressed-out embossment remains integral at least on both sides thereof, where the tool-engaging surfaces thereof are able to withstand very large tightening forces in the circumferential direction which permit a secure tightening of the clamp structure.

摘要： For the connection of two edges of areal parts which extend at least along one common section essentially parallel to one another, at least one retaining element is arranged at the one edge which form-lockingly engages from behind, as viewed in the edge direction, in a recess in the other edge. At least one projection arranged laterally offset at the one edge in relation to the retaining element in the direction of the engagement from behind, abuts form-lockingly at the part with the recess essentially in the edge direction. For the connection of the terminal edges of open ends of a ring-shaped clamping band, analogously a retaining tongue is provided, preferably in the center of the one edge with lugs projecting on both sides from the tongue which form-lockingly engages from behind in an essentially congruent recess in the other edge also arranged essentially centrally. One projection each is arranged in the one edge to both sides of the tongue, preferably arranged at the end of the one edge, whereby each projection form-lockingly abuts at the band-like part having the recess essentially parallel to the edge direction each in the direction toward the recess.

摘要： A clamp structure of the open type with mutually overlapping inner and outer band portions, in which two ears are provided disposed diametrically opposite one another and at least the outer band portion is provided with an additional opening on the side of its ear opposite the free end of the outer band portion to balance the clamp structure when installed on an object to be fastened thereby. For larger clamp sizes, the inner band portion may also be provided with an opening located on the side of the outwardly extending hooks of the mechanical interconnection opposite the free end of the inner band portion. The inner band portion may additionally be provided with an outwardly extending hook adapted to engage in the opening provided in the outer band portion so as to keep the two band portions axially aligned. Elastic stretchability may be imparted to the clamping band by one more sections having non-rectilinear lateral band portions on both sides of the center longitudinal clamping band plane, whereby one or more of such sections replace one or more of the openings.

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 performed 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.
