Definitions
- the present invention relates to improvements in the bridges of flat-band clamps used for the tightening of hose tubes and the like, such improvements being a precise geometry fold of the sides of the central area of said bridge, obtaining a deformation that it provides the bridge with greater inertia and the clamp with greater mechanical flability in its application.
- Spanish utility model of 1965 ES-0116670 is a tension clamp.
- Spanish patent ES-0317355P also from 1965, uses a screw to constrict the clamp.
- a flat-band metal clamp was used that incorporated fasteners from the ends free of the strap and a deformation bridge to constrict the clamp once mounted on the tube and thus achieve greater tightness, said bridge being large.
- clamps formed by a flat metal band and open at its ends. These ends are joined by fastening, forming a ring that is fixed on the tube to be tightened.
- the European patent EP-0491291 of Oetiker develops lateral appendages created from recesses in the upper area of the bridge. These appendages are lowered at an angle close to 45 °, as a side ramp, reaching a height equivalent to that of the clamp bridge legs. The upper part of the bridge, therefore, suffers a reduction in width as a result of the recesses made to form the lateral appendages.
- Mikalor has developed a new design of the flat band clamp head that guarantees, together with the new closing tool of said head with unit control of the effort of closing, also developed by Mikalor, that the tightening of the clamps is completely reliable, that is, it provides the necessary tightening to ensure the tightness in its application.
- the deformation of Mikalor object of the present invention obtains better yields because it uses the same bandwidth throughout the entire length of the bridge, making a deformation that creates two side walls perpendicular to the upper plane of the bridge or crossbar, being its union with the area not deformed of the regular and continuous bridge, by means of a curved surface.
- the mutual size and shape of the deformed and non-deformed parts of the sides of the bridge area are calculated in the present invention to ensure that the clamping of the clamps is completely reliable.
- the JP-63172085 patent of NHK Spring Co. develops ribs on both flanges of the upper area of the bridge, bending them inwards. Said ribs, whose central part protrudes inwards more than the two extreme parts, are located covering a small portion, transversely, of the upper area of the bridge, and almost the entire longitudinal extension of said bridge, presenting a curved outer profile. . A depression or depressions in the central part of the bridge crossing, regularly distributed and centered, of depth close to the height of folding of the flanges, complete said reinforced bridge.
- the WO-0070260 patent of NHK Spring Co represents a solution very similar to its Japanese patent JP-63172085, also describing ribs on both flanges of the upper area of the bridge, bending them inwards, and with depressions or drawing in the part Central of the bridge's crossbar.
- the ribs cover more than 60% of the bridge's length, fall at an angle of approximately 45 ° and are low in height. Said deformations are centered on the side of the bridge leaving a small portion of the bridge without affecting it in order not to increase the stiffness of the legs of the bridge and prevent them from breaking when their deformation is requested.
- the bridge represents a constructive whole in which there is a close dimensional relationship between all its elements, a relationship that is not comparable in the present invention that uses a totally different principle in the construction of lateral deformation. of the bridge, other proportions and, in short, other formative elements of the bridge.
- NHK patents describe deformations in the form of skirts or small side folds, similar to a sequin, and of length greater than 60% of the length of the bridge
- Mikalor constructs side walls with a completely straight and perpendicular exterior profile in a central area of the sides of the band, obtaining on the bridge three distinct and symmetrical zones with respect to a longitudinal axis and a transverse axis, adopting the bridge seen on the upper floor the general shape of an hourglass, the length of which is said straight walls in about 50% of the total bridge length.
- the formative rib of the skirts in NHK is curved to obtain maximum resistance in the center of the bridge and minimum in the contact areas of the bridge with the legs of the bridge, while in Mikalor there is a straight fold line, providing a uniform area in all its extension.
- the present invention relates to improvements introduced in the bridges of flat band clamps consisting of a selective bending of the central part of the sides of the upper or cross-section of the bridge, forming walls perpendicular to said crossbar, keeping intact a zone anterior and posterior of the cross-section of said bridge, in the longitudinal direction of the band, said bend being an angle close to 90 °, without intersections or discontinuities with the non-deformed part of the bridge, and the height of said bend being between 2.2 mm to 2.5 mm.
- the bridge of the invention has an elongated appearance and the general shape of an hourglass.
- the crossing of the bridge is completely flat and without drawing.
- the center of gravity of the bridge of the invention has been calculated to be located at a midpoint of the bridge and be of low height. All this results in a very high inertia and optimum performance of the type of clamp that incorporates the bridge of the invention.
- the main object, therefore, of the present invention is to provide a flat clamp with a cinching bridge that guarantees the reliability in the tightening thereof.
- Another object of the present invention is to provide a flat band clamp that is functional and reliable, providing inertia of the central and middle area of the bridge, not less than 1.7 mm 4 .
- Still another object of the present invention is to provide a flat band clamp with a clamping bridge that can be used with a certain degree of tolerance and elasticity against excessive tightening. Tolerance and elasticity provided by the same bridge that despite being irreversibly contracted, maintains a degree of flexibility that allows it to loosen excessive constriction of the hose.
- Figure 1 is a perspective representation of a clamp incorporating the improvements of the invention, once assembled and at a time prior to the constraint of the bridge.
- Figure 2 is another perspective view, like Figure 1, shown after constraining the clamp bridge.
- Figure 3 is a front view of the clamp bridge of the invention.
- Figure 4 is a top view of the clamp bridge according to the invention.
- the present invention consists of improvements in the flat band clamp bridges, in which straight bending lines (5) are formed in the central part of each of the sides of the upper part (4) of the bridge (2) of the clamp (1), folds (5) that form vertically descending side walls (7).
- the outer profile of the descending walls (7) is straight, as are the formative fold lines (5) of said walls (7).
- the joint or separation between the non-deformed parts (6) of the bridge (4) and the descending side walls (7) is regular and continuous, by means of a warped surface (8).
- the bridge according to the improvements of the invention has in top view the general shape of an elongated hourglass, in which the length of the descending walls (7) represents between 46% and 58% of the total bridge length ( two) .
- the side walls (7) have a vertical descent and resemble in combination with the bridge (2) the side partitions of an orthogonal building in which there are volumetric areas before and after said partitions, which correspond to areas (6) without warp, and that are of greater width, being cantilevered, that is, without the support of said lateral partitions corresponding to the descending walls (7).
- the bridge (2) of the invention has, like the known, two legs (3) that project outwards from the clamp and which are joined by a flat joint or traverse surface (4).
- the consequent deformation and constriction operation of the clamp (1) is carried out by means of inwardly clamping, simultaneous clamping, of the lateral legs (3) of said bridge (2). Said clamping reduces the diameter of the clamp (1) which results in a greater tightening on the hose to which it fits.
- the specific configuration of the improvements introduced in the present invention allows to control the shape of the bridge during the closing process of the clamp, obtaining very uniform and high results in the clamping, thus ensuring the hermetic mounting of the clamp. And its reliability.
- the deformed bridge adopting a certain shape and symmetrical, in which its legs (3) adopt the figure of an "that", which results in maximum performance in the clamp tightening.
- the arrangement of the descending side walls (7) acting as pillars against the deformation thereof results in an optimization of the force necessary to compress said bridge (2), compared to other previous solutions that construct the lateral deformations of the bridge in the form of eyelashes or skirts.
- warped joint surfaces (8) between the non-deformed parts (6) of the bridge (2) and the descending side walls (7).
- said warped walls (8) act in the two directions described, in a combination of both types of actions, reinforcing the resistance to folding the bridge and increasing the material that can be deformed.
- the height of the descending side walls (7) must be between 2.2 mm and 2.5 mm.
