DETAILED DESCRIPTION

FIGS.1-5show a handle1of a first embodiment according to the present invention. The handle1is used on an air pump2for a user to hold. The type of the pump2is not limited, and it can be a mini portable pump or a floor pump. The following embodiment uses a portable pump2as an example for description.

The handle1includes a limiting member10, a handle body20, a switch member30and a biasing member40. The limiting member10is adapted to connect with the air pump2and provided with a limiting recess11. The handle body20is pivotally connected to the limiting member10to be changeable between a folded position and a use position, and the handle body20is provided with a slot21. The switch member30is pivotally arranged in the slot21and provided with a restricting portion31detachably engaged with the limiting recess11. The restricting portion31is configured to engage with the limiting recess11when the handle body20is in the use position, and to disengage from the limiting recess11as the switch member30moved relative to the slot21. The biasing member40is arranged in the slot21and disposed between the handle body20and the switch member30, and the biasing member40is configured to elastically bias the switch member30toward the outside of the slot21.

In order to allow the restricting portion31of the switch member30to detachably engage with the limiting recess11of the limiting member10, the limiting member10is further provided with a limiting protrusion12adjacent to the limiting recess11and a guiding surface13formed at one side of the limiting protrusion12. The limiting recess11and the guiding surface13are respectively disposed at two opposite sides of the limiting protrusion12. The restricting portion31abuts against the guiding surface13when the handle body20is in the folded position, and the restricting portion31moves along the guiding surface13until the restricting portion31passes over the limiting protrusion12to engaged with the limiting recess11as the handle body20pivoted relative to the limiting member10.

Further, in order to facilitate the restricting portion31to move along the guiding surface13and to pass over the limiting protrusion12to engage with the limiting recess11, the guiding surface13may be a slope inclined toward the limiting protrusion12.

The limiting member10is further provided with a first pivoting hole14, and the handle body20is further provided with a second pivoting hole22aligned with the first pivoting hole14and communicated with the slot21. A first pivoting member50inserts through the first pivoting hole14and the second pivoting hole22to cause the handle body20pivotally connected to the limiting member10to be changeable between the folded position and the use position.

The switch member30is further provided with a pressed portion32opposite to the restricting portion31and exposed on the slot21for the user to press to pivot the switch member30. The handle body20is further provided with a third pivoting hole23communicated with the slot21, and the switch member30is further provided with a fourth pivoting hole33aligned with the third pivoting hole23. A second pivoting member60inserts through the third pivoting hole23, the switch member30and the fourth pivoting hole33to pivotally arrange the switch member30in the slot21.

In order to stably arrange the biasing member40between the handle body20and the switch member30, an inner wall surface of the slot21is provided with a first stopping portion211, and one side of the pressed portion32facing to the limiting member10is provided with a second stopping portion321. The biasing member40is provided with a central portion41, a first abutting portion42and a second abutting portion43. The first abutting portion42and the second abutting portion43are respectively disposed at two opposite sides of the central portion41. The second pivoting member60further inserts through the central portion41. The first abutting portion42abuts against the first stopping portion211, and the second abutting portion43abuts against the second stopping portion321. Furthermore, the biasing member40in the embodiment may be integrally wound by a U-shaped elastic metal to form the central portion41, the first abutting portion42and the second abutting portion43. Understandably, other springs or elastic bodies that can provide biasing force to the switch member30can also be used as the biasing member40.

In the embodiment, the limiting member10is further provided with a threaded hole15, and the air pump2includes a piston rod201having a threaded portion202detachably engaged with the threaded hole15to attach the limiting member10to the piston rod201.

As mentioned above, and as shown inFIG.3, when the handle body20is in the folded position, the handle body20, the limiting member10and the air pump2are in an I-shaped arrangement for easy storage, and the restricting portion31of the switch member30abuts against the guiding surface13of the limiting member10. Further, an inner wall surface of the slot21is provided with an engaging portion212engaged with an engaging groove203of the air pump2when the handle body20is in the folded position, so as to enhance the positioning function of the handle body20in the folded position.

As shown inFIG.4, the user can apply force to the handle body20to make the handle body20pivot relative to the limiting member10to change from the folded position to the use position. When the handle body20is in the use position, the handle body20and the limiting member10are in a T-shaped arrangement to facilitate the user to hold the handle body20to reciprocate the piston rod201for inflating. The restricting portion31moves along the guiding surface13until the restricting portion31passes over the limiting protrusion12to engaged with the limiting recess11, so that the handle body20cannot pivot relative to the limiting member10. Thus, the user's hand is prevented from being pinched by the handle body20when inflating, and make it easier for the user to hold the handle body20for reciprocating.

As shown inFIG.5, when the user intends to change the handle body20from the use position to the folded position, the pressed portion32can be pressed by an external force from the user to resist the outward biasing force of the biasing member40. The switch member30pivots relative to the slot21, and the second stopping portion321forces the second abutting portion43to move toward the first abutting portion42, so that the restricting part31is detached from the limiting recess11, and the handle body20is not limited by the switch member30and can pivot relative to the limit member10to change to the folded position. Once the user stops applying force to the pressed portion32, which will be elastically biased toward the outside of the slot21by the biasing member40and the return to expose on the slot21.

FIGS.6and7shows a handle1aof a second embodiment according to the present invention. The second embedment is substantially the same as the first embodiment. The main differences are that the limiting member10ais further provided with a outer threaded portion15a, and the air pump3includes a cylinder301having an inner threaded portion302detachably engaged with the outer threaded portion15a.

Although specific embodiments have been illustrated and described, numerous modifications and variations are still possible without departing from the scope of the invention. The scope of the invention is limited by the accompanying claims.
