Definitions

  • the present invention relates to an air pump according to the preamble of Claim 1 .
  • Bicycle air pumps are typically attached somewhere on the fame of the bicycle.
  • this has the disadvantage that these pumps are greatly in danger of theft and, in addition, may frequently fall out of the holders provided for this purpose. Therefore, possibilities have already been sought for stowing the air pumps better.
  • One possibility in this regard is offered by housing the air pump in the saddle post or in the seat tube of the bicycle.
  • Various technologies have been developed for fixing the air pump in the locations cited.
  • an air pump which replaces the saddle post and is removably connected to the saddle using a threaded screw is described in U.S. Pat. No. 5,499,858.
  • the saddle is removed from the seat tube together with the air pump and turned over, i.e., placed on the ground with the saddle first, the saddle simultaneously being used as a foot support during the pumping procedure.
  • the device described has the disadvantage, however, that the saddle is dirtied during the pumping procedure and, furthermore, the device is unhandy, since the saddle remains connected to the air pump.
  • a similar device is also described in U.S. Pat. No. 5,324,174, a saddle suspension additionally being integrated. It is extremely disadvantageous for all of these air pump devices that they must be specially adapted for each bicycle and are not universal usable for all common bicycle and saddle post types.
  • This clamping is achieved in that the cover of the carrier, the closure screw, is turned in an internal thread of the carrier.
  • This closure screw is conically shaped, through which the wall of the carrier is pressed against the inner tube of the saddle post.
  • an expandable ring may be provided on a groove, which is to prevent slipping in the axial direction.
  • the object of the present invention is therefore to provide an air pump which may be introduced easily, rapidly, and securely into the saddle post of the bicycle and also offers the conditions for housing a complete repair set for flat tires.
  • the air pump according to the present invention has a deformable element between the cylinder and the air outlet valve, which is movably connected to the cylinder.
  • the diameter of this element may be enlarged in relation to the cylinder by moving the air outlet valve.
  • the element is relaxed when the longitudinal axis of the cylinder and the longitudinal axis of the air outlet valve are at a specific angle, particularly 90° one another.
  • the pumping procedure may be performed in this position, for example.
  • the air pump according to the present invention is inserted with the handle first into the end opposite the saddle or, more precisely, into its opening. The air pump is inserted in this case until the deformable element is largely in the interior of the saddle post.
  • the deformable element By folding over the air outlet valve so that the longitudinal axis of the cylinder and the longitudinal axis of the air outlet valve run parallel to one another and/or are congruent, the deformable element is compressed, so that its diameter enlarges. The diameter is enlarged in this case until it corresponds at least to the internal diameter of the saddle post.
  • the air pump is thus clamped in the interior of the saddle post.
  • the locking of the air pump in the saddle post may thus be performed easily and rapidly, since less force is required for this purpose because of the lever effect. Since the element is deformable, it adapts itself to the saddle post, independent of possible irregularities or the precise shape. Since no special thread is required for this fixing, the air pump may be used universally and nearly independently of the diameter of the saddle post.
  • the air pump fits in nearly all common saddle posts.
  • a rubber seal in the form of a rubber disk or even a soft plastic element which may be deformed may be provided as the deformable element.
  • the handle of the air pump is implemented as a repair tool for the bicycle.
  • Two tool levers are removably connected to the piston rod instead of the typical pump handle for this purpose.
  • the tool is slipped over the handle of the piston rod and is removably connected to the cylinder. In this way, both the air pump and also the tool may be stowed in the interior of the saddle post in a compact way.
  • the tool may also remain fixed as the handle in the form of handle shells and may be used in this way, which is particularly advantageous when a relatively large amount of force must be applied using the tool. This is advantageous in the case of tool levers for removing tires, for example.
  • a cylindrical container is removably connected to the air outlet valve. This may be performed via a screw or plug-in connection, for example.
  • the cylindrical container in the form of a tube or cup may be filled with diverse objects, such as tools, replacement parts, repair kits, or similar objects. These are thus stored protected in the frame tube of the bicycle.
  • FIG. 1 shows an exemplary embodiment of the present invention in a partially cutaway view
  • FIG. 2 shows the exemplary embodiment of FIG. 1 integrated in a saddle post.
  • an air pump 1 also has all parts of a typical air pump.
  • a pump cylinder 2 is provided, in whose interior a piston (not shown in greater detail) is moved by a piston rod 3 .
  • a handle 4 is provided for moving the piston.
  • an air outlet valve 5 is provided, which is connected to the cylinder 2 so it may pivot or fold, illustrated by the arrow 10 .
  • a deformable element 6 is provided between cylinder 2 and air outlet valve 5 . It may be seen from FIG. 2 how the air pump 1 is insertable into the saddle post 50 and connected thereto.
  • the air pump 1 is inserted with the handle 4 first into the opening 52 of the saddle post 50 diametrically opposite the saddle 51 . This is performed in the state shown in FIG. 1 until the deformable element 6 is located at least just in the interior of the saddle post 50 .
  • the deformable element 6 By folding over the air outlet valve 5 , as illustrated by the arrow 10 in FIG. 1 , the deformable element 6 is deformed in such a way that its diameter increases; it is more or less compressed in the longitudinal direction.
  • its diameter d′′ at least corresponds to the internal diameter D of the saddle post 50 .
  • the air pump 1 is thus reliably and securely clamped in the interior 53 of the saddle post 50 .
  • the air outlet valve 5 is folded back into the position shown in FIG. 1 .
  • the deformable element 6 is relaxed again when the longitudinal axis, illustrated by the dashed line A of the cylinder 2 , is approximately perpendicular to the longitudinal axis a of the air outlet valve 5 . If the air outlet valve 5 is now pivoted around the joint 7 in arrow direction 10 , the longitudinal axes A and a run approximately parallel to one another, and/or are congruent with one another. As a result, the clamped state shown in FIG. 2 is achieved.
  • the air outlet valve 5 is equipped with a rounded end 8 which is diametrically opposite the air release end 9 .
  • the spacing of the outermost point 11 of the end 8 from the joint 7 is greater than the spacing of the side 12 of the air outlet valve 5 from the joint 7 .
  • the spacing between deformable element 6 and joint 7 is enlarged by the movement in the arrow direction 10 , through which the deformable element 6 is compressed.
  • the air pump 1 and the saddle post 50 are inserted into the frame tube 60 , illustrated by the arrow 61 .
  • the saddle post 50 is fixed in a typical way in the frame tube 60 .
  • the air pump 1 is now invisibly and securely housed in the interior of the bicycle.
  • the saddle post 50 is merely removed together with saddle 51 from the frame tube 60 and the air outlet valve 5 is folded over, through which the clamp of the deformable element 6 relaxes and the air pump 1 may thus be removed.
  • the handle 4 is implemented as a holder for tools 30 , 31 in the form of levers.
  • the tools 30 , 31 are connected removably to the piston rod 3 , via a thread (not shown), for example.
  • the tools 30 , 31 advantageously remain as the handle 4 in the form of handle shells. If the tools 30 , 31 are to be used, they are removed from the piston rod 3 and used. Alternatively to this, the tools 30 , 31 may be slipped over an extension of the piston rod 3 , which is then used as a handle for actuating the piston rod 3 , and removably connected to the cylinder 2 of the air pump 1 .
  • This may be removably connected by a thread provided on the cylinder 2 , indicated in FIG. 2 and provided with the reference number 14 .
  • the tools 30 , 31 are removed from air pump 1 so that it may be actuated for a pumping procedure.
  • the tools 30 , 31 are also attached via one end of the piston rod 3 and are connected via the thread 14 to the cylinder 2 .
  • the tools 30 , 31 are removed from the thread 14 through a rotational movement, but remain on the piston rod 3 , in contrast to the exemplary embodiment described above, and are then again used as a handle 4 .
  • a cylindrical container 20 is additionally provided in FIG. 1 , which may be removably connected to the air outlet valve 5 , illustrated by the arrow 25 . This connection may be produced via the screw connection shown in FIG. 1 , for example. As may be seen from FIG.
  • the air pump 1 according to the present invention having tools 30 , 31 and container 20 , may largely be housed in the interior of the saddle post 50 , inserted into the frame tube 60 , and thus stowed as a whole in the interior of the bicycle as a repair kit for flat tires.
