Definitions

  • the invention relates to a suction hose for suction of Gases, with a spout and with a clamping device for Clamping the grommet, especially on an exhaust pipe Vehicle, wherein the clamping device against each other deliverable Has clamping elements.
  • a clamp is made of two clamping elements for attachment to the exhaust pipe one Vehicle provided, the two clamping elements via a Toggle mechanism from a release position to a clamping position are transferable and vice versa.
  • the toggle mechanism via a pull rope at an attachment point of the hose attached so that when exceeded a limit the toggle mechanism is released and thus the exhaust pipe is released.
  • the invention is therefore based on the object of an improved Create suction hose for suction of gases, the one attachment of the spout to a variety of different ones Pipes made possible without additional conversion measures.
  • the Locking device are gradually tightened so far that the Clamping device with sufficient clamping effect at the end of the exhaust pipe is set.
  • the clamping device for numerous shapes and thicknesses of exhaust pipes are used, since the latching device delivers the clamping elements to one another made possible over a wide range. Because the clamping elements can be approximately punctiform and approximately can be provided with rubber buffers and the like, is the Suction hose according to the invention also for numerous different Forms of exhaust pipes can be used.
  • one of the Clamping device locally, preferably at working height, arranged actuating device for actuating the latching device intended.
  • the clamping device can be actuated for the operator in a particularly simple and ergonomic way achieve favorably by namely only in one actuated suitable height actuated is to the clamping elements against each other with the help of the locking device to send.
  • This is the annoying attaching the Clamping connection, which was previously carried out approximately at floor level had to be avoided.
  • the invention Suction hose on particularly convenient and ergonomic Attach it to and from an exhaust pipe to solve.
  • the locking device formed as a ratchet device, which by means of a Lever is gradually tightenable.
  • This measure allows a gradual delivery of the Locking device for fixing the clamping elements against each other achieve in a particularly simple manner, with an additional provided easy way to release the clamp connection can be.
  • the Locking device thus with a release device responding to train be coupled to cancel the clamping effect.
  • This measure can ensure that the Clamping device independently when driving in front of a vehicle solves.
  • a first of the clamping elements rigidly connected to the spout while a second of the clamping elements pivotally attached to the spout is and via a Bowden cable with the locking device is coupled.
  • This measure allows a local of the clamping device separate actuating device for the locking device to particularly simple, reliable and inexpensive Realize wisely.
  • the locking device can directly with the actuating device be coupled by a ratchet device is used by means of a lever, i.e. about can be operated by means of a handle.
  • a guide element for introducing the clamping device into the Exhaust pipe is on the spout a guide element for introducing the clamping device into the Exhaust pipe provided.
  • the spout is attached to the end of the Exhaust pipe and the insertion of a clamping element in the Exhaust pipe simplified.
  • the guide element is in a preferred further development this design as a compliant element that is preferably designed as a flexible shaft which from second clamping element protrudes outwards.
  • the spout can be used by the standing operator e.g. with the help of a foot comfortably on the exhaust pipe be plugged on.
  • a is on the spout Mirror provided for visual inspection when fastening the grommet.
  • the spout is on attached a flexible hose section to which one rigid pipe section connects, being a flexible Traction element, preferably one on the grommet and on the rigid Pipe section attacking tension spring, to stabilize the position Spout is provided.
  • Fig. 1 is a suction hose according to the invention, the total is designated by the number 10, only in his shown below, in which a handling by a standing operator is possible.
  • the suction hose 10 is at its top end with a flexible hose section 18 provided, for example, to a stationary on the ceiling arranged blower can lead or when in use on an assembly line or in facilities such as the TÜV on one Suction vehicle can be connected, which is movable via a Roller bearings in a suction slot channel in a known manner can be led.
  • the flexible hose section 18 is via a hose clamp 17 connected to a rigid pipe section 16, the upper End up at about working height for a standing operator located.
  • the rigid pipe section 16 extends further down to a height of about 30 to 40 cm above the bottom, as illustrated by a dashed line 19 in Fig. 1 is.
  • This is followed by another flexible one Hose section 14, which is slightly curved and from one flexible jacket 21 made of a resistant, elastic Material, such as a high quality neoprene.
  • the flexible jacket 21 of the flexible hose section 14 extends upwards over the rigid pipe section 16 and is attached to it with a hose clamp 15.
  • a spout 12 again fastened with a hose clamp 13.
  • the spout extends over an angle of the order of about 130 to 150 ° and has an inclined end face 11 with a Suction opening on that with an acute angle in the order of magnitude between about 20 and 40 ° pointing forward, so that itself a good adaptation to the slope of an arched Body panel at the rear of a vehicle results.
  • the spout 12 also consists of an elastic, very resistant Material that is also sufficient Has heat resistance, such as from a high quality Neoprene.
  • a clamping device is provided, the clamping elements 40, 42 protrude somewhat beyond the end face 11 of the spout 12, with a clamping element 40 outside the exhaust pipe 36 is located and the second clamping element 42 in the exhaust pipe 36 is introduced.
  • a latching device 22 is used to actuate the clamping device provided at the upper end of the rigid pipe section 16 in Working height is fixed for a standing operator and via an actuating device designated overall by the number 20 can be operated.
  • the locking device 22 is designed as a ratchet device, with a locking ring 24 into which a detent 26 engages, which a lever 28 in the form of a handle of the actuator 20 can be operated.
  • the latching action of the latching device can be achieved using a release device 30 be canceled.
  • the release device 30 comprises a pull lever 31 which is operated manually against the action of a spring can be pulled up to cancel the locking effect.
  • a Bowden cable 32 is also coupled to the release device 30, to allow the locking action to automatically is lifted when the vehicle drives up.
  • the locking device 22 is a Bowden cable 38 with the Clamping device on the spout 12 in connection, so that the suction hose comfortably by a standing operator on End of the exhaust pipe 36 of a vehicle can be attached.
  • a plate 54 is made on the lower inner surface of the spout 12 Metal provided with one end slightly above the outer end surface 11 of the spout 12 protrudes and at their outer end of the first clamping element 40 in the form of a rubber buffer is provided. On the plate 54 is also the second Clamping element 42 attached to one end of a pivot lever 58, the inside of the spout 12 located at the end of the Plate 54 on a bearing 56 via a pivot axis 59 is set.
  • a receptacle 48 for the Bowden cable 38 is provided, on which the Bowden cable 38 with its flexible sheath 50 is attached via a rigid end piece 51.
  • the Bowden cable 38 has a flexible core 52 made of wire, the led around a roller 49 attached to the receptacle 48 is and is attached to the pivot lever 58.
  • a mirror 55 is provided, which is slightly laterally the spout (12) protrudes and forwards to below first, rigidly fixed clamping element 40 is guided.
  • a flexible tension element 44 preferably in Form of a tension spring, provided with at its upper end an application point 46 on the rigid pipe section 16 is and at its lower end with an attack point 45 in front area of the spout 12 near the suction opening is in turn fastened with a point of attack 45 (see FIG. 1).
