Definitions

  • the present invention relates to a pump for filling bicycle tires, comprising a pump head having at least a first opening, which is fluidically connectable to a valve of a bicycle tire, and a first pump part, in which the pump head may be arranged at least in sections.
  • the at least one first opening can not be fluidly connected to a valve of a bicycle tire, but not in the first position in the second position.
  • this can be achieved by arranging the at least one first opening in the second position outside the first pump part and in the first position inside the first pump part.
  • the pump head and / or the first pump part comprise sealing means which in the first position of the pump head can seal them with respect to the first pump part.
  • a particularly simple operation of the pump results when, by a rotational movement of the first and the second pump part To each other, the pump head from the first to the second position and / or from the second to the first position can be transferred. This can be achieved, for example, by turning the first pump part relative to the second pump part.
  • a further advantageous operability results when the linear movement of the first and the second pump part relative to each other can be blocked by a rotational movement of the first and the second pump part relative to each other.
  • the pump comprises a compressed gas cartridge, wherein the compressed gas from this compressed gas cartridge via the pump head in a valve of a bicycle tire can be introduced.
  • the pump head comprises more than a first opening for connection to differently designed valves of a bicycle tire.
  • the pump head 1 further comprises two radially outwardly extending projections 13, which are arranged on opposite sides of the pump head 1 (see Fig. 3, Fig. 4 and Fig. 5 ). Furthermore, the pump head 1 in his in Fig. 5 the first pump part end region facing a groove 14 into which a sealing ring 15 can be introduced.
  • the sleeve 8 can be pushed onto the end of the pump head 1 facing away from the first pump part 3.
  • the sleeve 8 has a bore 16 which is at least partially aligned with the first opening 9 in the pushed-on state.
  • a sealing ring 17 can be arranged in a corresponding groove (see Fig. 3, Fig. 4 and Fig. 5 ).
  • the piston rod 4 is designed substantially as, preferably at least partially transparent, tube.
  • the piston rod 4 has at its the pump head 1 facing end (see Fig. 5 ) on two ends open slots 21 which are arranged on opposite sides and in Longitudinal direction of the piston rod 4 extend. In these slots 21, the projections 13 of the pump head 1 can engage for a rotationally fixed connection between the pump head 1 and piston rod 4. Spaced to the slots 21, a radially outwardly projecting, circumferential stop 22 on the outside of the piston rod 4 is formed.
  • the piston rod 4 may further comprise a longitudinally extending window 23 through which a manometer scale (not shown) may be viewed.
  • a manometer tube 24 is provided with a surrounding pressure gauge spring 25 (see also Fig. 3 ).
  • an external wind 26 is provided at the end remote from the first pump part 2 end of the piston rod 4, (see Fig. 4 and Fig. 5 ).
  • the second pump part 3 is formed substantially tubular and has at each of its ends an internal thread 31, 32 (see Fig. 3 and Fig. 5 ).
  • these internal threads 31, 32 are external threads 33, 34 of end caps 35, 36 screwed (see Fig. 5 ).
  • end cap 36 At the side facing away from the first pump part 2 end cap 36 also two bayonet projections 37 are provided which can cooperate with the bayonet projections 29.
  • Fig. 1 and Fig. 3 show the assembled pump in the first position of the pump head 1, in which it is completely received in the first pump part 2, so that their in Fig. 3 flush left ends.
  • the first opening 9 is also completely received by the first pump part 2, so that it is protected from dirt.
  • the bayonet projections 29 and 37 are locked together so that the piston 5 located in the second pump part 3 is fixed to the end cap 36.
  • the piston 5 and the associated piston rod 5 can not go to the left in Fig. 3 move out of the second pump part 3 out.
  • the first pump part 2 is fixed to the piston rod 4 via the screwed-on ring 20 which bears against the projection 22, the axial or linear movement of the two pump parts 2, 3 is also blocked relative to one another.
  • the pump head 1 facing the end of the piston rod 4 is received by the channel 11 of the pump head 1, wherein at the same time protrude the projections 13 of the pump head 1 in the slots 21 inside.
  • the air pressure built up in this way in the channel 11 acts on the pump head 1 facing, possibly sealed, the end of the pressure gauge spring 25 so that it is compressed more or less depending on the size of the pressure.
  • the pressure for the user can then be displayed via a corresponding scale arranged on the manometer tube 24 or the piston rod 4 (not shown).
  • the piston rod 4 at its in Fig. 4 right end has a bore 38 through which air from the space between the manometer tube 24 and piston rod 4 can escape.
  • the pump head 1 By a rotation of the first against the second pump part 2, 3 in a different direction, the pump head 1 can be transferred again into the first, inserted position (see Fig. 1 and Fig. 3 ). At the same time thereby also the locking of the bayonet projections 29 and 37 can be achieved, so that the axial movement of the pump parts 2, 3 is blocked to each other.
