Definitions
- the invention relates to an air pump according to the preamble of claim 1.
- Bicycle air pumps are usually attached anywhere on the frame of the bicycle.
- the disadvantage here is that on the one hand they are at risk of theft and on the other hand they can often fall out of the holders provided for this purpose. For this reason, options for stowing the air pump better were soon sought.
- One way to do this is to place the air pump in the seat post or in the seat tube of the bicycle.
- Various techniques have been developed to fix the air pump in the locations mentioned. For example, an air pump is described in US Pat. No. 5,499,858, which replaces the seat post and is detachably connected to the saddle by means of a screw thread. To operate the pump, the saddle and air pump are removed from the seat tube and turned over. H.
- the jamming is achieved by screwing the cover of the carrier, the so-called screw connection, into an internal thread of the carrier.
- This screw connection is conical, whereby the wall of the carrier is pressed against the inner tube of the seat post.
- an expandable ring can be provided on a groove, which should prevent slipping in the axial direction.
- the screwing process makes it more difficult to fix the carrier in the seat post, since considerable forces have to be used for stable fixing in order to increase the diameter of the carrier. As a result, the insertion and removal of the tool holder is complicated, requires a certain amount of physical strength and takes a comparatively long time.
- the object of the present invention is therefore to provide an air pump which can be easily, quickly and safely inserted into the seat post of a bicycle and which offers the prerequisites for accommodating a complete repair kit for flat tires.
- the air pump according to the 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 can be increased by moving the air outlet valve relative to the cylinder.
- the element is relieved when the longitudinal axis of the cylinder and the longitudinal axis of the air outlet valve are at a certain angle, in particular 90 °, to one another. In this position, the pumping process can be carried out, for example.
- the air pump according to the invention is placed with the handle first in the end opposite the saddle or more precisely in its opening introduced. The air pump is inserted until the deformable element is mostly inside the seat post.
- the deformable element By folding the air outlet valve in such a way that the longitudinal axis of the cylinder and the longitudinal axis of the air outlet valve run parallel to one another or coincide, the deformable element is pressed together, so that its diameter increases. The diameter is increased so that it corresponds at least to the inside diameter of the seat post. This will clamp the air pump inside the seat post. The locking of the air pump in the seat post is consequently easy and quick to carry out, since low forces are sufficient for this due to the leverage effect. Since the element is deformable, it hugs the seat post, regardless of any bumps or the exact design. Since no special thread is required for this fixation, the air pump can be used universally and almost independently of the diameter of the seat post.
- a special adaptation of the air pump to manufacturer-specific seat posts is therefore not necessary; rather, the air pump fits in almost all common seat posts.
- a sealing rubber in the form of a rubber washer or else a soft plastic element which can be deformed can be provided as the deformable element.
- the handle of the air pump is designed as a repair tool for the bicycle.
- two tool levers are detachably connected to the piston rod.
- the tool is put over the grip of the piston rod ⁇ and is releasably connected to the cylinder of the air pump. This makes it possible to stow both the air pump and tools inside the seat post in a compact manner.
- the tool in the form of grip shells can also remain fixed as a handle and be used in this way, which is particularly advantageous when a relatively large amount of force has to be applied with the tool. This is advantageous, for example, in the case of tool levers for releasing the tire.
- a cylindrical container is detachably connected to the air outlet valve. This can be done for example by a screw or plug connection.
- the cylindrical container in the form of a tube or Bechers can be filled with various objects, such as tools, spare parts, patches or similar objects. This protects them in the frame tube of the bike.
- Figure 1 shows an embodiment of the invention in a partially sectioned view.
- Fig. 2 shows the embodiment of FIG. 1, integrated in a seat post.
- an air pump 1 also has all the parts of a conventional air pump.
- a pump cylinder 2 is provided, in the interior of which a piston (not shown in 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 that it can pivot or fold, represented by the arrow 10.
- a deformable element 6, in particular a sealing rubber, is now provided between the cylinder 2 and the air outlet valve 5. 2 shows how the air pump 1 can be inserted into and connected to the seat post 50.
- the air pump 1 is inserted into the opening 52 of the seat post 50 opposite the saddle 51 with the handle 4 first. This happens in the state shown in FIG. 1 until the deformable element 6 is at least just inside the seat post 50.
- the deformable element 6 By folding the air outlet valve 5, as shown by the arrow 10 in FIG. 1, the deformable element 6 is deformed in such a way that its diameter increases; it is quasi compressed in the longitudinal direction.
- the shortening of the deformable element 6 in the longitudinal direction, represented by the distance I 'and I causes an increase in the diameter, represented by d' and d".
- the diameter d After increasing the diameter d 'of the deformable element 6, its diameter d "corresponds at least to the inside diameter D of the seat post 50.
- the air pump 1 is reliably and securely clamped inside 53 of the seat post 50.
- the air outlet valve 5 is folded back into the position shown in FIG. 1. As can be seen from a comparison of FIGS.
- the deformable element 6 is relieved again when the longitudinal axis, represented 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 about the joint 7 in the direction of the arrow 10, the longitudinal axes A and a run approximately parallel to one another or are brought into register with one another. As a result, the clamping state shown in FIG. 2 is reached.
- the air outlet valve 5 is equipped with a rounded end 8, which is opposite the air outlet end 9.
- the distance of the outermost point 11 of the end 8 of the joint 7 is greater than the distance of the side 12 of the air outlet valve 5 from the joint 7. Consequently, the distance between the deformable element 6 and the joint 7 is increased by the movement in the direction of arrow 10, whereby the deformable element 6 is pressed together.
- the air pump 1 and the seat post 50 are inserted into the frame tube 60, represented by the arrow 61.
- the seat post is 50 fixed in a conventional manner in the frame tube 60.
- the air pump 1 is now invisible and safely housed inside the bicycle. To remove the air pump 1, only the seat post 50 together with the saddle 51 is removed from the frame tube 60 and the air outlet valve 5 is folded down, as a result of which the deformable element 6 is released and the air pump 1 can thus be removed.
- the handle 4 is designed as a holder for tools 30, 31 in lever form.
- the tools 30, 31 are detachably connected to the piston rod 3, for example via a thread (not shown).
- the tool 30, 31 remains in the manner of a grip shell, advantageously as a handle 4. If the tool 30, 31 is to be used, it is used by the Piston rod 3 released and put into use.
- the tool 30, 31 is put over an extension of the piston rod 3, which then serves as a handle for actuating the piston rod 3, and is detachably connected to the cylinder 2 of the air pump 1.
- This can be detachably connected, for example, by a thread provided on the cylinder 2, indicated in FIG. 2 and provided with the reference number 14. In this case, the tool 30, 31 is removed from the air pump 1 so that it can be actuated for the pumping process.
- the tool 30, 31 is also attached over one end of the piston rod 3 and is connected to the cylinder 2 via the thread 14.
- the tool 30, 31 is released from the thread 14 by a rotary movement, but, in contrast to the exemplary embodiment described above, remains on the piston rod 3 and then again serves as a handle 4.
- FIG. 1 there is also a cylindrical one Container 20 is provided, which can be detachably connected to the air outlet valve 5, represented by the arrow 25. This connection can be made, for example, via the screw connection shown in FIG. 1.
- the air pump 1 according to the invention with tools 30, 31 and container 20 can largely be accommodated in the interior of the seat post 50, can be inserted into the frame tube 60 and can therefore be stowed entirely as a repair kit for flat tires inside a bicycle.
