Definitions

  • the invention relates to a hose clamp made of a particular metallic clamping band with an inner band portion, an overlapping outer end portion and a closing device having an opening in the outer end portion and in the inner band portion in the closed state of the hose clamp engaging in the opening hook.
  • the locking device is configured to receive the force applied to tension the hose clamp, which may be significant, particularly with thin and relatively hard hose materials.
  • hose clamps which can be disassembled for repair work, for example, have a lavishly designed locking device which projects beyond the clamping profile and / or requires a special pliers or other adapted tool for releasing.
  • the invention has for its object to provide a hose clamp, which is designed so that it can be easily disassembled with no change clamp profile and without special tool.
  • the hose clamp shown in Fig. 1 consists of a clamping band 10, wherein in the closed state of the terminal outer end portion 11 has two openings 12, 13, a clamping device 14 in the form of a so-called "Oetiker ear" and a laterally open channel in the present embodiment 15.
  • the other, inner band part 16 is provided with two hooks 17, 18 for engagement in the openings 12, 13 and at the end thereof with a tongue 19, which in the tensioned state (not shown) of the hose clamp in the channel 15th
  • the ear is narrowed by means of pliers.
  • the corner portions 20 of the outer clamping band end portion 11 are bent outwardly, so that there is a gap for insertion of a screwdriver or other disassembly tool on both sides.
  • FIG. 2 differs from that of FIG.
  • bent edge portions 22 instead of the bent corner regions 20 on both sides of the end portion 11 bent edge portions 22 are provided which form opposite the inner band part 16 column. Also in this embodiment, the outer end portion 11 can be separated by inserting a screwdriver under one of the bent edge portions 22 of the inner band member 16. Alternatively, a pair of pliers can be attached to both edge regions 22 at the same time.
  • a part 25 of the front edge of the outer end portion 11 is bent for insertion of about a screwdriver.
  • a transverse slot 30 is punched into the outer clamping band end section 11 in the region between the clamping device 14 and the inner opening 12, which has a transverse edge 31 facing away from the end of the outer end section 11.
  • a recess 32 is embossed in the inner band part 16, a transverse to the circumferential direction of the hose clamp, facing away from the end of the inner band member 16 transverse edge 33 (or exact transverse surface).
  • the transverse edges 31 and 33 are at a distance from each other.
  • FIG. 7 differs from that of FIG.
  • transverse slot 35 is disposed between the outer opening 13 and the end of the outer clamping band end portion 11.
  • an opening 40 is stamped into the outer clamping band end section 11, which opening is delimited by a first transverse edge 41 facing away from the end of the outer end section 11 and a first semicircular edge 42.
  • a recess 43 impressed which is bounded by a transverse to the circumferential direction of the hose clamp, facing away from the end of the inner band member 16 second transverse edge 44 and a second semicircular arc-shaped edge 45.
  • the two transverse edges 41, 44 form a gap in the closed state of the hose clamp. As illustrated in FIGS. 9 and 10, this hose clamp can be opened by inserting the tip 34 of about a screwdriver into the space between the two transverse edges 41, 44 and rotating it about the screwdriver axis.
  • a pawl 50 is bent out on the inner band member 16, which is opposite to the outer band end and serves to hook 17, 18 in engagement with the openings 12, 13 and so the hose clamp to installation in the closed state to keep.
  • disassembling the pawl 50 may be first bent out (Fig. 9), so that the force to be applied for mutual displacement of the two band parts by the disassembly tool is not too large.
  • the opening 40 is disposed between the free end of the outer clamping band end portion 11 and the outer opening 13.
  • the aperture 40 may be similar to the transverse slot 30 in FIG. 4 between the tensioning device 14 and the inner aperture 12.

Abstract

L'invention concerne un collier de serrage pour tuyau constitué d'une bande de serrage (10) pourvue d'une partie intérieure (16), d'une partie d'extrémité extérieure de bande de serrage (11) chevauchant ladite partie intérieure et d'un dispositif de fermeture, lequel présente, dans la partie d'extrémité extérieure (11) de la bande de serrage, une ouverture (12, 13) et, dans la partie intérieure de la bande (16), un crochet (17, 18) s'insérant dans l'ouverture (12, 13) une fois le collier de serrage fermé. La partie d'extrémité extérieure (11) de la bande de serrage est pourvue d'une conformation destinée à la mise en place d'un outil de démontage permettant de détacher les deux parties (11, 16) de la bande l'une de l'autre. La conformation peut être une fente transversale (30) dans la partie d'extrémité extérieure (11) de la bande de serrage, pourvue d'un premier bord transversal (31) opposé à l'extrémité de ladite partie d'extrémité de bande de serrage, et un évidement (32) pourvu d'un second bord transversal (33) s'étendant transversalement à la direction circonférentielle du collier de serrage et opposé à l'extrémité de la partie intérieure (16) de la bande est ménagé dans la partie intérieure (16) de la bande. Une fois le collier de serrage fermé, les deux bords transversaux (31, 33) sont espacés l'un de l'autre pour l'insertion de l'outil de démontage (34).
