Abstract
The invention relates to an improved arrangement of an air pump which can be inserted into the seat pillar (50) of a bicycle and which comprises a cylinder (2), a piston with a piston rod (3), a handle (4) and an air outlet valve (5) which is displaceably connected to the cylinder (2). According to the invention, a deformable element (6) is provided between the cylinder (2) and the air outlet valve (5), the diameter (d) thereof being able to be increased by flipping over the air outlet valve (5) such that the longitudinal axis (A) of the cylinder (2) and the longitudinal axis (a) of the air outlet valve extend in an at least substantially parallel manner. The air pump (1) can be blocked in the seat pillar (50).
Claims7
An air pump, which is insertable into a saddle post (50) of a bicycle, having a cylinder (2), a piston having a piston rod (3), a handle (4), and an air outlet valve (5) movably connected to the cylinder (2), characterized in that a deformable element (6) is provided between cylinder (2) and air outlet valve (5), whose diameter (d) may be enlarged by folding over the air outlet valve (5), so that the longitudinal axis (A) of the cylinder (2) and the longitudinal axis (a) of the air outlet valve (5) at least largely run parallel, the air pump (1) being lockable in the saddle post (50).
The air pump according to one of the preceding claims,
- characterized in that a cylindrical container (20), whose diameter is smaller than the diameter of the frame tube (60), is removably connected to the air outlet valve (5).
The air pump according to one of the preceding claims,
- characterized in that the deformable element (6) is a rubber seal.
