Definitions

  • the present invention relates to a vacuum cleaner, and more particularly, to a bendable extension pipe of a vacuum cleaner which enables the operator of the cleaner to clean the small places underneath furniture such as a bed and a couch with convenience.
  • a vacuum cleaner draws in dust from a cleaning surface along with ambient air using a suction force which is generated by a suction motor provided inside a cleaner body.
  • a fluid passage is sealingly formed connecting the cleaner body and the suction brush while contacting on the cleaning surface.
  • the extension pipe and the suction brush are usually at a fixed angle and as a result, it is inconvenient for an operator to clean lower places such as places underneath the bed or couch. That is, the operator has to lower his/her body, keep the suction brush in contact with the cleaning surface and turn the extension pipe to clean the underside places. Even with the extension pipe and the suction brush disposed at an adjustable angle, however, there still exists an inconvenience because the operator has to bend his body to put the suction brush underneath the furniture.
  • An object of the present invention is to provide a bendable extension pipe for a vacuum cleaner which has an improved structure to enable an operator to perform a cleaning operation without having to bend or lower his/her body, but bending the extension pipe through a simple manipulation of a few buttons.
  • a bendable extension pipe for a vacuum cleaner with a body bent by a button manipulation, the bendable extension pipe forming a sealed fluid passage between a vacuum cleaner body and a suction brush.
  • the bendable extension pipe includes a first extension pipe, a second extension pipe rotatably connected with the first extension pipe, a locking button elastically disposed on the first extension pipe, to restrict rotation of the first and the second extension pipes, and a sealing cover for preventing the locking button from moving out of joint from the first and second extension pipes and sealing the first and the second extension pipes.
  • the locking button is formed on a seating protrusion which is protruded from a side of an axis of a rotation of a joint which movably connects the first extension pipe and the second extension pipe.
  • the locking button includes at least one interfering rib protruding along the outer circumference and a restriction projection for restricting the rotation of the first and the second extension pipes.
  • the seating protrusion includes at least one guide projection formed on the outer circumference and a sliding groove formed in the locking button to coincide with the guide projection. With a push and release of the locking button, the sliding groove is guided by the guiding projection to prevent a rotation of the locking button.
  • An elastic member is disposed between the locking button and the seating protrusion. With the push of the locking button, the elastic member exerts a recovery force in the direction of a release from the locking button.
  • the second extension pipe includes a slot plate with a sliding slot for a sliding engagement with the seating projection.
  • the sliding slot includes one open end.
  • a locking part is formed in a position corresponding to a restriction projection to selectively lock the restriction projection in accordance with a displacement of the restriction projection in an axial direction.
  • the locking part is separated from the slot plate by a distance equal to, or greater than the thickness of the restriction projection.
  • FIG. 3 is a drawing of a perspective view illustrating a bendable extension pipe according to an embodiment of the present invention before the bending, with a sealing cover being omitted;
  • FIG. 1 is a perspective view illustrating a bendable extension pipe 100 for a vacuum cleaner according to an embodiment of the present invention.
  • the bendable extension pipe 100 includes first and second extension pipes 110, 120 which are bendably connected to each other according to a push and release of a locking button 130.
  • a sealing cover 140 prevents a suction loss of the connecting parts and also prevents the locking button 130 from moving out of joint from the first and second extension pipes in the axial direction.
  • the first extension pipe 110 includes a cylinder joint J1 which has an opening (not shown) at a side facing the second extension pipe 120, and approximately at the center of the cylinder joint J1, a seating protrusion 111 is formed overlapping with the rotational axis.
  • the locking button 130 is movably disposed on the seating protrusion 111 for the push and release movement, and in one example, the seating protrusion 111 may be inserted in the locking button 130 with the intervention of an elastic member S therebetween.
  • at least one guide projection 111a and sliding groove 130a are formed on each of the seating protrusion 111 and the locking button 130 in a complementary manner.
  • the locking button 130 when the locking button 130 is pushed or released by the guide projection 111a which is engaged in the sliding groove 130a in the outer circumference, the locking button 130 is guided such that the locking button 130 turns in association with the turning of the first extension pipe 110 to the same rotational angle.
  • An interfering rib 131 is formed on an outer circumference of the locking button 130 to prevent the locking button 130 from moving out in the axial direction, and a restriction projection 132 is formed also on the outer circumference of the locking bottom 130 to restrict the rotational angle of the first and the second extension pipes 110 and 120.
  • At least one interfering rib 131 with a larger diameter than the locking button 130 may be formed in the circumferential direction as shown in FIG. 2, to prevent the locking button 130, which is exposed outside of the sealing cover 140, from moving out in the axial direction.
  • the interfering rib 131 may be arranged symmetrically to be supported evenly on the sealing cover 140 and not to be tilted.
  • At least one restriction projection 132 may be formed in a circumferential direction, each on appropriate locations which do not coincide with the interfering rib 131.
  • the restriction projection 132 may be formed with a smaller height than the interfering rib 131, and additionally, the restriction projection 132 may be tapered on a predetermined side to require less force of an operator in bending the first and the second extension pipes 110 and 120.
  • the second extension pipe 120 includes a cylinder joint receiving portion J2, which has a complementary shape as the cylinder joint J1 of the first extension pipe 110 for a turnable engagement.
  • the cylinder joint receiving portion J2 includes a slot plate 121 which has a sliding slot 121a for a sliding engagement with the seating projection 111 to a proximity of the center of the second extension pipe 120, and a locking part 122 which selectively contacts with the restriction projection 132 to restrict a rotation of the first and the second extension pipes 110, 120, respectively.
  • the sealing cover 140 prevents a suction loss from occurring between the cylinder joint J1 and the cylinder joint receiving portion J2, and between the first and the second extension pipes 110 and 120.
  • the sealing cover 140 may have first and second covers 141, 142 to prevent the locking button 130 from moving out in the axial direction.
  • the first cover 141 includes a button hole 141a to expose the locking button 130.
  • the button hole 141a includes a size that corresponds to the outer circumference of the locking button 130.
  • the button hole 141 a may have a size equal to, or greater than the outer circumference of the locking button 130, and smaller than the outer circumference of the locking button 130 with the interfering rib 131, such that the interfering rib 131 is supposedly on an inner circumference of the first cover 141 to prevent the locking button 130 from moving out in the axial direction.
  • the restriction projection 132 When the operator wants to clean places such as underneath a bed or a couch, the operator presses the locking button 130, and accordingly, the restriction projection 132 is moved out of the locking part 122 to a position in which the restriction projection 132 can be passed through the space between the locking part 122 and the slot plate 121.
  • the restriction projection 132 contacts the inner circumference of the space defined between the locking part 122 and the slot plate 121 and becomes rotatable.
