Definitions

  • the present disclosure relates to clamping clips, and more particularly, to clamping clips with a stepless inner surface.
  • KR 20-0455752 Y1 discloses a clamping clip made of a clamping band, the two end portions of which overlap each other in the closed condition of the clamping clip.
  • the overlapped inner band portion is tapered and engages in a complementarily shaped tongue channel provided on the overlapping outer band portion.
  • the tongue and the tongue channel have an oblong shape. In both cases the tongue and the tongue channel effect a mutual centering.
  • a clamping clip comprising a clamping band the two end portions of which overlap one another in a closed condition of the clamping clip, the clamping band including a tongue arranged at an overlapped inner band portion, and a tongue channel arranged in an overlapping outer band portion, the tongue channel being complementary to the shape of the tongue for receiving the tongue, wherein the tongue includes a root part that decreases in width from a first width to a second width, the second width being less than the first width, and an end part adjoining the root part, the end part having a third width equal to the second width.
  • It is the object of the invention is to provide a clamping clip with a stepless inner surface that can be mounted both axially and radially in a simpler and safer manner.
  • the clamping clip formed in accordance with the invention is not pre-positioned and therefore does not require the band ends to be unhooked for radial installation.
  • the invention ensures the desired steplessness after radial installation. At the same time, it ensures that after any deformation of the clamping clip, e.g., during shipping and handling, the tongue is guided positively and safely into the tongue channel when the clamping clip is closed by means of a pair of pliers.
  • the shape of the tensioning hooks described below allows the clamping clip of the invention to be closed and re-opened with commercially available pliers. Furthermore, the clamping clip of the invention is reusable.
  • the clamping clip is provided with a tolerance compensation so that it can be mounted also on hard to non-compressible materials.
  • FIG. 1 is a perspective representation of a clamping clip in the open condition
  • FIGS. 2 and 3 show the clamping clip of FIG. 1 in a closed and tightened condition, seen from two different directions;
  • FIG. 4 is a partial view of the clamping clip of an alternative embodiment in the closed condition
  • FIGS. 5 and 6 are partial views of further embodiments of the clamping clip, each in the closed condition
  • FIG. 7 is a partial view of the clamping clip according to another embodiment
  • FIGS. 8 and 9 are a side view and a perspective view of the clamping clip according to further modifications.
  • the term “substantially” is synonymous with terms such as “nearly,” “very nearly,” “about,” “approximately,” “around,” “bordering on,” “close to,” “essentially,” “in the neighborhood of,” “in the vicinity of,” etc., and such terms may be used interchangeably as appearing in the specification and claims.
  • proximate is synonymous with terms such as “nearby,” “close,” “adjacent,” “neighboring,” “immediate,” “adjoining,” etc., and such terms may be used interchangeably as appearing in the specification and claims.
  • the term “approximately” is intended to mean values within ten percent of the specified value.
  • clamping clip shown in FIGS. 1-3 consists of clamping band 10 with overlapping band portions 11 and 12 .
  • clamping band 10 includes the following parts: tongue 13 , inner connecting hook 14 projecting from the outside of clamping band 10 , tension hook 15 also projecting outward, slot 16 extending in the circumferential direction of the clamping clip, tongue channel 17 formed on the inner side of clamping band 10 , and outward projecting outer tension hook 18 .
  • Tongue 13 has end part 20 , which is narrower than the full band width and has parallel side edges and a rounded tip, and trapezoidal root part 21 which increases in width from end part 20 to the full width of the clamping band.
  • Tongue channel 17 has a shape complementary to tongue 13 .
  • connecting hook 14 engages in tensioning hook 18 .
  • the clip can be gripped with universal pliers, which engage the ends of two tensioning hooks 15 and 18 facing away from each other. At these ends, tensioning hooks 15 , 18 each have nose 22 , 23 projecting in the circumferential direction to prevent the pliers from slipping off.
  • Waves 25 , 26 are stamped into the band parts between slot 16 and the respective outer edge of clamping band 10 , which waves compensate for tolerances between the circumference of the clamping clip and the respective object to be clamped. Waves 25 , 26 are offset from each other in the circumferential direction in order to achieve a 360° all-round support without interruptions in the inner surface of the clamping clip.
  • end part 30 of outer band portion 12 is bent and runs diagonally outwards at an angle.
  • Tensioning hook 15 is provided with inclined surface 31 facing end part 30 , which serves as a ramp for end part 30 when closing and tightening the clamping clip.
  • inwardly projecting point bead 32 is stamped into clamping band 10 , which reduces the friction between outer band portion 12 and inclined surface 31 and simultaneously stiffens outer band portion 12 against deformation.
  • tensioning hooks 15 and 18 with noses 22 and 23 and the formation of inclined surface 31 on tensioning hook 15 in conjunction with point shaped bead 32 and bent end part 30 on outer band portion 12 ensure the reusability of the clamping clip.
  • the clamping clip is provided with a tolerance compensation in the form of waves 25 , 26 . This measure is not necessary with every clamping clip; it can be useful depending on the properties of the object to be clamped.
  • the clamping clip is equipped with tolerance compensating waves 35 which, unlike in FIG. 2 , extend over the entire width of clamping band 10 but lie within an area supported by inner clamping band portion 11 . This feature results in easier deformability of the clamping clip for softer objects to be clamped.
  • tolerance compensating waves 36 are provided which again extend over the entire width of clamping band 10 and are curved in the radial direction in such a way that their outer edges 37 lie close to the object to be clamped in the tightened condition of the clamping clip. This avoids the risk of damage to elastomer materials, such as bellows, in the event of contact during component rotation. At the same time, the clamping clip is protected against contamination, which in extreme cases can impair the tolerance compensation.
  • tensioning hook 15 arranged on the inner band portion 11 can have several, preferably three, projections 38 facing away from the inner end of the band, which ensure a secure gripping of the plier tool used for closing the clamping clip and thus a secure closing.
  • a single projection would not only be more susceptible to breakage, but could also lead to a rotation of the plier jaw.
  • tensioning hook 18 arranged on outer band portion 12 can be provided with several, preferably three, projections 39 on its plier engaging edge remote from the outer band end.
  • opening hook 40 is arranged on the side of outer band portion 12 remote from the outer end of the band.
  • the closed clamping clip can be opened by means of a plier tool engaging tensioning hook 15 and opening hook 40 .
  • the opening process is assisted by curved band portion 41 , which is arranged between opening hook 40 and tensioning hook 18 on outer band portion 12 and in which a second curved band portion formed on inner band portion 11 engages when the band clamping clip is closed.
  • the second curved band portion is omitted from the drawing. Its outer height is greater than the clear height of curved band portion 41 arranged on outer band portion 12 . The difference in height results in a bias which favorably affects the opening process. Furthermore, the inner surface of curved band portion 41 facing the outer end of the band is formed as a ramp.
  • opening hook 40 which serves to engage the pliers, may be provided with several, preferably three, projections 44 similar to the edge of tensioning hook 15 .
  • inclined surface 48 with centering groove 43 is formed at the end of outer band portion 12 which is longer than in FIG. 4 .
  • Projection 45 formed on connecting hook 14 engages in this groove when the clamping clip is closed in order to prevent misalignment of the clamping clip.
  • Centering groove 43 also serves to reinforce inclined surface 48 in order to prevent its deformation during the closing movement.
