Abstract

A floor pump includes a main body and a supporting device. The supporting device includes a base and a first leg. The base is fixed to the main body and has a first stopping flange and a second stopping flange. The first leg is pivotally connected to the base to approach or move away from the base. The first leg has a front end and a rear end. When the first leg is approached to the base, the first leg is limited by the first and second stopping flanges to a folded position or an unfolded position. When the first leg is in the folded position, the front end is approached to the main body. When the first leg is in the unfolded position, the front end is distal away from the main body.

First claim

The invention claimed is:

1 . A floor pump comprising:
a main body; and a supporting device including a base and a first leg, wherein the base is fixed to the main body and has a first stopping flange and a second stopping flange, wherein the first leg is pivotally connected to the base and rotatable relative to the base about a first rotation axis, and the first leg is axially movable along the first rotation axis to approach or move away from the base, wherein the first leg has a front end and a rear end, wherein the first leg forms a front section between the front end and the first rotation axis, and the first leg forms a rear section between the rear end and the first rotation axis, wherein the first leg has a first side and a second side opposite to the first side on an outer periphery thereof along a radial direction of the first rotation axis; wherein when the first leg is moved away from the base, the first leg is rotatable relative to the base, and when the first leg is approached to the base, the first leg is limited to a folded position or an unfolded position; wherein when the first leg is in the folded position, one side of the front section adjacent to the first side is close to the first stopping flange, and one side of the rear section adjacent to the second side is close to the second stopping flange, and the front end is approached to the main body; wherein when the first leg is in the unfolded position, one side of the front section adjacent to the second side is close to the first stopping flange, and one side of the rear section adjacent to the first side is close to the second stopping flange, and the front end is distal away from the main body.

2 . The floor pump as claimed in claim 1 , wherein the base is connected to an axial rod having an outer periphery sleeved by an axial sleeve, wherein the first leg has a pivot hole along an axial direction of the first rotation axis, wherein the floor pump further includes a pivot mechanism, wherein the pivot mechanism includes a biasing member, a cover sleeve, and a pull collar, wherein the biasing member sleeves on the axial sleeve, wherein the cover sleeve inserts into the pivot hole and sleeves on the biasing member, wherein one end of the biasing member along the axial direction of the first rotation axis abuts against the axial sleeve and another end of the biasing member abuts against the cover sleeve, and wherein the pull collar is connected to the cover sleeve and located at one side of the first leg opposite to the base.

3 . The floor pump as claimed in claim 2 , wherein the side of the first leg opposite to the base has an engaging recess disposed adjacent to the pivot hole, wherein one side of the pull collar adjacent to the first leg has an engaging flange engaged with the engaging recess, wherein the first leg and the pull collar is axially movable along the first rotation axis synchronously, and when the first leg is moved away from the base, the first leg and the pull collar is rotatable relative to each other synchronously.

4 . The floor pump as claimed in claim 3 , wherein the base further has a third stopping flange and a fourth stopping flange, wherein the third stopping flange and the first stopping flange are respectively disposed on opposite sides of the base and form a symmetrical structure, wherein the fourth stopping flange and the second stopping flange are respectively disposed on opposite sides of the base and form a symmetrical structure, wherein the supporting device further includes a second leg, wherein the second leg is pivotally connected to the base and rotatable relative to the base about a second rotation axis, and the second leg is axially movable along the second rotation axis to approach or move away from the base, wherein when the second leg is moved away from the base, the second leg is rotatable relative to the base, and when the second leg is approached to the base, the second leg is limited, and the second leg and the first leg are respectively arranged on two opposite sides of the base and form a symmetrical structure.

5 . The floor pump as claimed in claim 3 , wherein the base has a first limiting flange, wherein when the first leg is in the folded position, the first leg is limited between the first stopping flange and the first limiting flange, wherein when the first leg is in the unfolded position, the first leg is limited between the first limiting flange and the second stopping flange.

6 . The floor pump as claimed in claim 5 , wherein the base further has a third stopping flange, a fourth stopping flange, and a second limiting flange, wherein the third stopping flange and the first stopping flange are respectively arranged on two opposite sides of the base and form a symmetrical structure, wherein the fourth stopping flange and the second stopping flange are respectively arranged on the two opposite sides of the base and form a symmetrical structure, wherein the second limiting flange and the first limiting flange are respectively arranged on the two opposite sides of the base and form a symmetrical structure, wherein the supporting device further includes a second leg, wherein the second leg is pivotally connected to the base and rotatable relative to the base about a second rotation axis, and the second leg is axially movable along the second rotation axis to approach or move away from the base, wherein when the second leg is moved away from the base, the second leg is rotatable relative to the base, and when the second leg is approached to the base, the second leg is limited, and the second leg and the first leg are respectively arranged on the two opposite sides of the base and form a symmetrical structure.

7 . The floor pump as claimed in claim 1 , wherein the main body has a footrest, wherein the footrest has a connection flange extending in a vertical direction, wherein an outer periphery of the connection flange has a T-shaped cross section in a horizontal direction, wherein the base has a connection groove and is movable in the vertical direction to cause the connection groove to sleeve on the connection flange, and wherein an inner periphery of the connection groove has a T-shaped cross section in the horizontal direction.

8 . A floor pump comprising:
a main body; and a supporting device including a base and a first leg, wherein the base is fixed to the main body and has a first stopping flange and a second stopping flange, wherein the first leg is pivotally connected to the base and rotatable relative to the base about a first rotation axis, and the first leg is axially movable along the first rotation axis to approach or move away from the base, wherein the first leg has a front end and a rear end, wherein the first leg forms a front section between the front end and the first rotation axis, and the first leg forms a rear section between the rear end and the first rotation axis, wherein the first leg has a first side and a second side opposite to the first side on an outer periphery thereof along a radial direction of the first rotation axis, and wherein one side of the first leg adjacent to the base has an engaging groove; wherein when the first leg is moved away from the base, the first leg is rotatable relative to the base, and when the first leg is approached to the base, the first leg is limited to a folded position or an unfolded position; wherein when the first leg is in the folded position, the first side is close to the first stopping flange, and one side of the rear section adjacent to the second side is close to the second stopping flange, and the front end is approached to the main body; wherein when the first leg is in the unfolded position, the engaging groove sleeves on the first stopping flange, and one side of
