Definitions

  • the invention relates to a clamping lever closure with a band for a barrel or other packaging container, consisting of a lever bearing part fastened to a band end, which has a base plate and two right-angled cheeks, a pivoting lever pivotable on a hinge pin of the lever bearing part with two cheeks and one connecting the same Back, a counter bearing part for the other band end and a connecting part which is held on a hinge pin of the tensioning lever and a hinge pin held between cheeks of the counter bearing part.
  • a tension lever lock of this type is known from DE-A1-2655 111.
  • Such a clamping lever closure with a band serves to hold the lid on a barrel or a similar packaging container.
  • the band can be a profiled band, a flat band or a wire.
  • the front edge of the packaging container and the front edge of the lid each have projections which together form a channel into which the tape is inserted.
  • the tensioning lever itself requires more space than the belt, so that the tensioning lever protrudes over the insertion channel. Difficulties arise especially when the projections are quite large and the insert channel is narrow, which is preferable for a firm fit of the cover.
  • the object of the invention is such a design of a tension lever lock of the type mentioned that the same can be inserted into a narrow channel and has as little protrusion as possible over the top of the channel and still has a high stability.
  • the invention gives the clamping lever lock a low profile. Because the flat tab dips deep into the bearing parts. It lies practically on the base plates of the bearing parts. Since the tab is arranged between the cheeks, a protrusion across the plane of the tensioning band is completely eliminated. The hinge axes can be placed very deep, i.e. as close as possible to the base plates of the bearing parts. Overall, this is very favorable for the overall height and the closing force. The back of the tensioning lever can also remain low. In addition, only a single tab is provided, which lies and is guided between the cheeks of the bearing parts. As a result, the width dimension in the axial direction of the hinge pin is kept small, so that the clamping lever lock can be inserted into a narrow groove of a barrel lid.
  • the tab increases the stability of the clamping lever lock. Because the tab lies between the cheeks of the opposing bearing parts and bridges the channel formed between the cheeks, so that high torsional and impact forces can be absorbed. This is extremely important for stability.
  • the invention differs in a non-obvious manner from the prior art in that the single tab is embedded in the shell of the tensioning lever and a large opening path is ensured while ensuring high stability.
  • the closure is kept narrow in the radial and axial directions.
  • a tension lever lock for a lock spring chain for wide neck flasks in which a tab is arranged between the cheeks of the tension lever.
  • the cheeks of the tensioning lever are connected at the front end by a cross bar.
  • Such a tensioning lever is unsuitable for a tensioning lever lock of the present type because an essentially smooth back with a tensioning lever end that can be used as a handle is required for handling the tensioning lever.
  • the tension lever lock for a spring lock chain can offer no suggestion to solve the problem underlying the invention.
  • a further development of the invention provides that the tab fills the height of the cheeks of the lever bearing part and the cheeks of the counter bearing part. This embodiment ensures a high rigidity of the clamping lever lock despite the low overall height.
  • a V-shaped notch is provided in the back of the tab in the immediate vicinity of the hinge pin, which is in the open position over the transverse edge of the cutout.
  • the distance of this notch from the hinge pin corresponds approximately to the distance of the hinge pin from the end of the cutout in the back of the clamping lever, so that the notch can lie over the transverse edge of the cutout and thus ensure a large opening path of the closure.
  • the hinge pin can be guided in the longitudinal slots of the cheeks. The notch ensures that the cocking lock can be opened without difficulty. The tab cannot get caught or jammed inside the tensioning lever.
  • the end edges of the incision have bevels or roundings that face away from one another. These bevels ensure that the incision slides securely over the hinge pin of the lever bearing part.
  • the invention provides that the base plate of the lever bearing part has a trough-shaped extension which has an embedding for the counter bearing part. This increases the stability of the tension lever lock in the area of the joint. A buckling of the tension lever lock when closing is suppressed. The tilting moments or canting forces that occur when closing are safely absorbed by this trough-shaped extension.
  • the invention provides that the tension lever end is offset on one side only across the width of the back. This one-sided arrangement of the clamping lever end serving as a handle ensures that the clamping lever rests in the front area of the container, so that the clamping lever can always be closed securely.
  • Fig. 1 shows in dash-dotted lines a section of the upper part 1 of a barrel, on which protrusions 2 and protrusions 5 are formed.
  • a cover 3 engages over the front edge of the upper part 1 and stands on the projections 2 with angled flexible tongues 4.
  • the projections 2 of the upper part 1 or the overlying tongues 4 of the cover 3 form in connection with the projections 5 a circumferential channel for inserting a tension wire 6 and for receiving the tension lever lock 7.
  • the channel itself should be as narrow and deep as possible to ensure a secure closure to achieve the barrel lid.
  • the tension lever lock requires several parts lying next to one another in the transverse direction, so that the width dimension cannot be reduced arbitrarily.
  • the invention therefore proposes the following solution:
  • the clamping lever lock 7 comprises a lever bearing part 8 which has a base plate 9 and cheeks 10 bent at right angles.
  • the bearing part 8 is clamped to the end of the tensioning wire 6 by means of bending tabs 11 and stamped connections.
  • the counter bearing part 12 has a base plate 14 and cheeks 15 which protrude at right angles.
  • a tensioning lever 17 On a hinge pin 16, which is arranged between the cheeks 10 of the lever bearing part, a tensioning lever 17 is mounted, which has a back 18 and two opposing cheeks 19, the front cheek 19 in the drawing being broken away in part to accommodate the arrangement of the make other closure parts more clearly visible.
  • the back 18 has a cutout 20 which extends from the hinge pin 16 to a further hinge pin 21 which spans the cheeks 19 of the tensioning lever 17.
  • a tab 22 On the hinge pin 21, a tab 22 is mounted as a connecting part. This tab 22 is also held on a hinge pin 23 which spans the cheeks 15 of the counter bearing part 12.
  • the tab 22 is a flat sheet metal blank.
  • the tab 22 has an incision 24 which engages over the hinge pin 16 in the closed state of the tension lever lock according to FIG. 2.
  • the tab 22 is received between the cheeks 10 of the lever bearing part and the cheeks 15 of the counter bearing part.
  • the height of the tab 22 corresponds to the height of the cheeks 10 and 15. In the closed state, the tab 22 bridges the gap 25 between the ends of the cheeks 10 and 15 and thereby forms an internal stiffening of the tension lever lock.
  • the cocking lever lock has a very small width.
  • the maximum width of the clamping lever lock is determined by the distance between the cheeks 19 of the clamping lever 17.
  • the tab 22 is in the closed state on the base plate 9 of the lever bearing part 8 and the base plate 14 of the counter bearing part 12.
  • the hinge pins 23 and 21 can be located a short distance from these base plates.
  • the hinge pins are accommodated in the respective cheeks of the bearing parts, so that the effective width of the clamping lever lock is small.
  • the tab 22 represents a direct connection between the cheeks 10 and 15, cf. Fig. 2, so that a high torsional rigidity of the clamping lever lock in the plane of the tension wire 6 is given.
  • the modified embodiment of the invention shown in FIGS. 4-6 has longitudinal slots 31 in the cheeks 19 of the tensioning lever 17, in which the hinge pins 21 for the tab 22 are guided.
  • the hinge pin 21 can move within the longitudinal slots 31 in the longitudinal direction of the cheeks when the tension lever lock is actuated. This contributes to the enlargement of the opening path.
  • a V-shaped notch 27 is provided, which is located at a short distance from the hinge pin 21.
  • the distance of the notch 27 from the hinge pin 21 corresponds approximately to the distance of the transverse edge of the cutout 20 from the adjacent end of the longitudinal slots 31.
  • This notch 27 lies over the transverse edge of the cutout 20 when the tension lever lock according to FIG wide opening is guaranteed.
  • this notch makes it possible for the tab to be able to be carried out essentially over its full width up to the end and in particular via the hinge pin 21, so that jamming or tilting of the tab is excluded.
  • the base plate 9 of the lever bearing part 8 has a trough-shaped extension 28 into which the base plate 14 of the counter bearing part 12 is inserted.
  • This trough-shaped extension 28 provides a guide for the base plate 18 and ensures high transverse rigidity for the closure. In particular, transverse forces and canting forces can be absorbed when actuated, in particular when the clamping lever is closed.
  • 28 bevels 32 and 33 are provided on the mutually directed end edges of the bearing parts 8 and 12 or the extension. As a result, the cocking lever lock lies better in a narrow channel and is easier to operate. In particular, damage to the channel walls of the barrel is excluded.
  • the clamping lever end 29 is formed on one side according to FIG. 4 with respect to the center line of the back 18, so that it fits into the front of the barrel and does not hinder the closing process.
  • This tensioning lever end 29 also lies in the closing groove of the cover or of the upper barrel part.
