Definitions

  • This invention is related to a hose coupling which enables fastening hoses in electrical vacuum cleaners with accessories such as handles, extension pipes or suction nozzles.
  • hoses which generally have helical threaded surface structures are used between the body and the accessories.
  • a hose coupling which ensures the pipes, handles or suction nozzles to be fixed in a stable or in a non- stable manner, is fixed on the end of the hose which is not connected to the electrical vacuum cleaner. If a sound connection between the hose and the hose coupling is not achieved, a reduction in efficiency and deformation or fracturing of the hose during usage occurs due to air leakage. Benefiting from the helical threaded surface structure of the hose in order to fix the hose coupling is a known method.
  • adhesive substances are used for preventing dislocation or loosening of the hose coupling during usage which is manufactured so that it can be fixed on the helical threaded surface structured hose.
  • the hose coupling is fixed on the hose with additional fastening parts which increase cost and the fastening is durable for only a short time.
  • the European Patent No. EP0376691 discloses a hose fastening part which has projections on its side walls for fixing the hose and which has a rugged structure on the propping surface of the end section of the hose in order to prevent loosening and dislocation by rotating.
  • the Japanese Utility Model No. 59-2753 discloses a flange made up of two parts comprising a circular projection on the end of the hose and a canal, fixed peripherally on the said projection which enables the hose to make a relative movement in the inner surface and a vacuum accessory connected on the said flange.
  • the American Patent US4625998 discloses a hose fastening part which is connected to the hose with a threaded structure and which comprises a flange which is curled inwards in the propping surface in order to fasten the hose and a canal structure.
  • the object of this invention is to provide a hose coupling which enables fastening the hose in electrical vacuum cleaners with elements such as handles and extension pipes or suction nozzles without the need of adhesive substances or additional parts.

  • the electrical vacuum cleaners comprise a hose (1) which has preferably a flexible and helical threaded structure that inclines to the right and left, a handle (2) which enables the user to hold it, a pipe (3) which is connected to the handle (2) and which is made up of metal or preferably hard plastic material, a suction nozzle (4) which is used by being fixed to the end of the pipe (3) in order to clean rugs and/or hard floors and a hose coupling (5) which enables the hose (1) to be fastened on the handle (2) and the pipe (3) or the suction nozzle (4).
  • the hose (1) has a helical threaded structure which is identified with an inclination angle (B) which inclines freely to the right and to the left and pitch (H), comprising a threaded inner surface (15) and a threaded outer surface (16).
  • the hose coupling (5) comprises a hose recess (9) wherein the hose (1) is connected and fastened, an inlet opening (10) wherein the end section of the hose (1) is inserted to fix it by rotating, a propping surface (11) on which the end section of the hose is set against it to fix it by rotating, a sealing extension (12) which ensures sealing when the handle (2), the pipe (3) or the suction nozzle (4) is mounted, a flange (13) which enables the pipe (3) or the suction nozzle (4) to fit inside the hose coupling (5) and one or more latches (14) which ensure that the handle (2), the pipe (3) or the suction nozzle (4) is not dislocated after they have been mounted.
  • Hose recess (9) comprises an inner wall (7) which is in contact with the inner surface (15) of the hose (1), an outer wall (8) which is in contact with the outer surface (16) and one or more projections (6) which form almost a right angle with the central axis of the hose (1) and which are almost parallel to each other, which enable the hose coupling (5) to be fastened by rotating on both the right and left helical hoses (1) and which enable fastening without the need of another part, an appliance or an adhesive substance.

  • the vertical distance between the projections (6) in the projection group which are made up of more than one projection (6) is equal to each other and almost to the pitch measurement (H) of the helical threaded structure of the hose (1).

  • the projections (6) are parallel to each other and vertical to the central axis of the hose (1), the inclination angle (B) of the helical threaded structure of the hose (1) is forced to approach zero.
  • the helical threaded structure of the hose (1) between the projections (6) allows the formation of a fractured helical structure by being somewhat deformed.
  • the inclination angle (B) between the projections (6) when the hose coupling (5) is rotated each time the number of the projections (6) which are in contact with the hose (1) that is forced to approach zero and consequently the friction surfaces on which pressure is applied by setting against each other is increased.
  • the end of the hose (1) reaches the propping surface (11), the force required for taking off the hose coupling (5) by rotating it in the reverse direction reaches the maximum value and a strong locking between the hose coupling (5) and the hose (1) is obtained.
