Definitions

  • TITLE Clamp for securing elongated objects and systems including such a clamp
  • This invention relates to a clamp for securing elongated objects such as pipes, tubes, hoses and cables to structures such as frames and to systems including such a clamp.
  • Such clamps are known for a broad range of applications, such as installation of conduits in buildings and industrial installations as well as hydraulic and other conduits in vessels and vehicles.
  • a disadvantage of such clamps is that securing the elongated objects is relatively cumbersome and accordingly time consuming and costly.
  • the clamps according to German utility model 1 960 916, German patent application 30 19 303, French patent application 2 852 656 and United States patent 3 462 804 need to be fastened to the base structure by a screw or a bolt, which requires a hole to be drilled in the base structure and is relatively cumbersome.
  • the clamp according to 6 809 257 can be mounted to a base structure more easily, because it includes an anchor leg to be inserted into a hole, but this also requires a hole in the base structure to which the clamp is to be secured.
  • this clamp requires a hole in the base structure to which it is to be mounted.
  • dismounting without damaging the clamp requires that the anchor leg can be reached from behind the structure to which it is mounted.
  • a fixing portion of the clamp being formed as a stud engagement portion for engagement to a stud, such as a T-stud or a stud bolt is also mentioned, but a solution avoiding making the securing of the clamps to the stud less cumbersome and accordingly time consuming and costly, than for instance the securing of the initially discussed conventional clamps to the weld plates is not provided thereby.
  • this object is achieved by providing a clamp according to claim 1.
  • the clamp By securing at least one of the clamping members to the weld plate by a snap-in anchor the clamp can be mounted to a base structure by welding the plate thereto so that no hole in the base structure is required and at least one of the clamping members can be mounted to the weld plate very quickly.
  • Fig. 1 is a top plan view of an example of a clamp embodying the present invention
  • Fig. 2 is a side view in cross-section along the lines II -II in Fig. 1;
  • Fig. 3 is a side view in cross-section along the lines II-II in Fig. 1 of the clamp shown in Fig. 1 in combination with a base structure and a pair of tongs;
  • Fig. 4 is a side view in cross -section similar to Fig. 3 of a system comprising a clamp according Figs. 1-3 with four clamping members stacked for receiving two tubes; and Fig. 5 is a side view in cross -section of a second example of a clamp according to the invention.
  • the clamp 1 is a clamp for securing an elongated object 2 such as a pipe, a tube, a hose or a cable to a structure 3.
  • the structure may for instance be a frame or the bodywork of a vehicle, a machine or a ship.
  • Such structures are typically designed to particular loads, which may also be variable loads so that fatigue considerations need to be taken into account, and need to meet strict security standards. It is therefore in many cases not allowed or at least undesirable, that holes are made in the structure for securing tubing such a hydraulic, pneumatic pipes and electric cables, in particular because the positions of such holes are difficult to foresee during the design of the structure.
  • the clamp according to the present example consists of a weld plate 4 weldable to a structure such as the structure 3, a clamp body consisting of a first clamp body member 5, a second clamp body member 6 and a cap 7 releasably mounted against each other and, in part directly and in part indirectly, secured to the weld plate 4.
  • the weld plate 4 is welded to the structure 3 by a spot-weld 8 applied through an opening 9 in the weld plate 4.
  • the opening 9 is circular, but it may also be elongate as indicated in Fig. 1 by dashed lines 9', which allows to align the weld plate 4 in a situation where a bolt or screw is used for fixing the weld plate 4 to a base structure.
  • Surface treatments of the base structure 3, such as galvanizing and/or painting are preferably applied after the weld plates 4 have been welded to the structure 3, the structure 3, to counteract corrosion at the fixation points of the weld plates 4.
  • the first and second clamp body members 5, 6 are shaped to leave a passage 10 for the elongated object 2 between the first and second clamp body members 5, 6.
  • the elongated object 2 need not be clamped in the passage 10 with significant clamping pressure.
  • the first clamp body member 5 has snap -in anchors (sometimes designated as "snap-in fingers") 11 and the weld plate 4 has anchoring edges 12. The snap-in anchors 11 engage the anchoring edges 12, thereby keeping the clamp body 5, 6 releasably secured to the weld plate 4.
  • the clamp body Since the clamp body is secured to the weld plate 4 by snap -in anchors 11, the clamp body can be fixed to the structure 3 easily, while no holes in the structure 3 are required, since the weld plate 4 can be welded to the structure 3.
  • the clamp body can be of a relatively soft and accommodating material such as plastic, while the weld plate 4 can be of a metal suitable to be welded to the metal of the structure 3, and for instance be of steel if the structure 3 is of steel and be of aluminium if the structure 3 is of aluminium.
  • the clamp body members are preferably made of plastic material, and preferably an engineering thermoplastic such as polyamide (PA) or polyoxy- methylene (POM).
  • the anchors 11 are part of the first clamp body member 5 and the anchoring edges are part of the weld plate 4, it is in principle also possible to provide that the anchors are part of the weld plate and the anchoring edges are part of the first or second clamp body member.
  • a pair of snap-in anchors instead of a pair of snap-in anchors, a single snap-in anchor, for instance in combination with a hook or centrally located, is also conceivable within the framework of the present invention.
  • the weld plate 104 may be directly coupled to the second clamp body member 106. However, if, as in the clamp according to the example shown in Figs.
  • the first clamp body member 5 that is mounted to the weld plate 5 comprises the snap -in anchors 11 that engage the weld plate 4 for keeping the first clamp body member 5 secured to the weld plate 4, the clamp body member 5, can be reliably secured to the weld plate 4, before the second clamp body member 6 clamping the elongated object 2 to the first clamp body member 5 is mounted.
  • the second clamp body member 6 is coupled to the first clamp body member 5 by snap-in anchors 13 engaging anchoring edges 14 as well, so that also the second clamp body member 6 can be secured very quickly and very easily.
  • the snap -in anchors 11 coupling the first clamp body member to the weld plate 4 are generally located in the plane indicated by the line III -III in Fig. 1 and the snap -in anchors 13 coupling the first clamp body member 5 to the second clamp body member 6 are generally located in the plane indicated by the line II-II in Fig. 1. Because the positions of, on the one hand, the anchors 11 and, on the other hand, the anchors 13 are staggered in circumferential sense about a central axis 15 of the clamp 1, the space available adjacent to the passage 10 can be used particularly efficiently, so that a compact clamp 1 is obtained.
  • the anchoring edge 12 extends along a circle, such that, in mounted condition, the first clamp body member 5 is pivotable relative to the weld plate 4 about the axis 15 concentrical with that circle. This allows the clamp body 5, 6 to be angularly aligned with the elongate object 2 after the weld plate 4 has been fixed to the base structure 3, so that the weld plates 4 do not need to be oriented accurately to secure the clamp in an orientation with its opening 10 parallel to the elongate object 2.
  • the clamp body members 5, 6 are rotatable about a full 360°, it is also possible to provide for a more limited pivotability of the clamp body members, for instance by providing that the anchoring edge of the weld plate or the clamp body or bodies connected thereto extend over a circle section only.
  • the side of the second clamp body member 6 facing away from the first clamp body member 5 and a side of the weld plate 4 facing the first clamp body member 5 are shaped correspondingly for allowing a further clamp body member 5' identical to the first clamp body member 5 to be coupled to the side of the second clamp body member 6 facing away from the first clamp body member 5.
  • a double clamp suitable for securing two elongate members in mutually spaced, parallel or crossing relationship is obtained.
  • Further clamp bodies can be added in the same manner to obtain clamps suitable for securing more than two elongate bodies.
  • the cap 7 is mounted only to the second body member 6' most remote from the weld plate 4.
  • the weld plate 4 can also be fixed in manners other than by welding, for instance by a bolt 58 extending through the hole 9 in the weld plate.
  • the base structure 53 to which the weld plate 4 is fixed is a U-shaped frame structure of which one leg comprising a base 66 to which the weld plate 4 is mounted and another leg comprises a coupling 67 for suspending the U-shaped frame structure 53, for instance, as in the present example, from a threaded rod 68.
  • a system for suspending elongate objects from a frame or from a structure such as a ceiling is obtained.
  • the U-shaped frame structure 53 may also be provided in other sizes for carrying single or multiple clamps.
  • the clamp 1 according to the present example is further equipped with shields 19, 20 of the snap-in anchors 11, 13. Passages 20, 21 are provided in the shields 19, 20 adjacent to the respective snap -in anchors 11, 13 for operating the snap-in anchors 11, 13 via the respective passages 21, 22.
  • the shields 19, 20 make unauthorized access to the snap-in anchors 11, 13 difficult and shield the snap -in anchors against accidental release of the snap- in anchors 11, 13.
  • the shields 19, 20 also form a rounded smooth outer surface of the clamp 1, so that injuries and damage due to body parts or objects caught behind clamps is counteracted.
  • the shields also shield cavities of the clamp 1 from accumulation of dirt.
  • the openings 21, 22 may also be closed off by plugs or otherwise after mounting of the clamp 1.
  • the shield of the first clamp body member 5 includes a skirt 19 of the first clamp body member 5 extending to the weld plate 4, the weld plate 4 may be of a flat design, projecting from the base structure 3 over a small distance. This is particularly advantageous if the base structure 3 has to undergo further processing steps, before the clamp body is mounted thereto.
  • the skirt 21 covers the weld plate 4, so that a seam on the outside of the clamp between the weld plate 4 and the clamp body is avoided.
  • the snap-in anchors 11, 13 extend past the associated anchoring edges 12, 14 on a side of the anchoring edges opposite of the associated passage 21, 22 in the shield 19, 12 adjacent to the respective snap-in anchor 11, 13, the snap-in anchors bend inwardly during mounting and for releasing the snap-in connection. This facilitates disassembly of the clamp, because the snap-in anchors 11, 13 can be released by pushing from the outside inwardly against the snap-in anchors 11, 13. This can easily be achieved by for instance a pair of tongs 23 of which fingers 24 pointing inwardly are of a cross-section that allows the fingers 24 to pass through the passages 21, 22.
  • the tongs 23 may for instance be of a design as shown in Fig. 3.
  • abutments 25 limit deformation of the snap-in anchors 13 to a deformation closely beyond a deformation allowing full release of the snap -in anchors 13 from the anchoring edge 14, so that damage to the snap-in anchors 13 by exertion of too large release forces thereon is counteracted.
  • the snap-in anchors 11 are spaced from an outside end of the adjacent passages 21 over a distance when deformed to an extent allowing full release of the snap-in anchors 11 from the anchoring edges 12.
  • the clamp 1 is part of a system that further includes a tool in the form of a pair of tongs 23 having operating fingers 24 insertable into the passages 21 and having a free end having a length measured to an abutment 26 not insertable into the passages 21 such that, at maximum insertion of the operating fingers 24, the deformation of the snap -in anchors 11 remains limited to a deformation closely beyond the deformation allowing full release of the snap - in anchors 11 from the anchoring edge 12. Thereby damage to the snap-in anchors 11 of the first clamp body member 5 is counteracted, because the maximum deformation of the snap-in anchors 11 achievable with the tool 23 is limited by the abutments contacting the outside of the shield 19.
  • the first clamp body member 105 is equipped with a notch 127 for keeping the first clamp body member in place during mounting.
  • first clamp body member 105 and the elongate object 2 to be secured are held between the second clamp body member 106 and the weld plate 4.
