Abstract
A manually guided implement having a tool driven by an internal combustion engine, which draws combustion air in via an air filter disposed on an air filter base. The air filter is secured to the implement via a releasable securement device that includes a first securement element, and a second securement element that cooperates with the first securement element. The securement elements can be released from one another, or connected to one another, by means of a rotational movement about an axis of rotation. To achieve easy handling of the air filter, the first securement element is fixedly connected to the air filter.
Claims19
A manually guided implement having a tool driven by an internal combustion engine, comprising:
- an air filter disposed on an air filter base, wherein said internal combustion engine is adapted to draw combustion air in through said air filter;
- and
- a releasable securement device for securing said air filter to said implement, wherein said securement device includes a first securement element fixedly connected to said air filter, and a second securement element that cooperates with said first securement element, wherein said first and second securement elements are adapted to be released from one another, or to be connected to one another, by means of a rotational movement about an axis of rotation, wherein one of said securement elements is a clamp and the other of said securement elements is a securement bolt having at least one recessed holding portion, and wherein said clamp is provided with at least one resilient arm.
A manually guided implement having a tool driven by an internal combustion engine, comprising:
- an air filter disposed on an air filter base, wherein said internal combustion engine is adapted to draw combustion air in through said air filter;
- and
- a releasable securement device for securing said air filter to said implement, wherein said securement device includes a first securement element fixedly connected to said air filter, and a second securement element that cooperates with said first securement element, wherein said first and second securement elements are adapted to be released from one another, or to be connected to one another, by means of a rotational movement about an axis of rotation, wherein said securement device is adapted to exert on said air filter a force that is effective in the longitudinal direction of said axis of rotation, and wherein at least one abutment is provided against which said air filter is supported in the longitudinal direction of said axis of rotation.
A manually guided implement having a tool driven by an internal combustion engine, comprising:
- an air filter disposed on an air filter base, wherein said internal combustion engine is adapted to draw combustion air in through said air filter, and wherein said air filter is provided with filter material and a seal;
- and
- a releasable securement device for securing said air filter to said implement, wherein said securement device includes a first securement element fixedly connected to said air filter, and a second securement element that cooperates with said first securement element, wherein said first and second securement elements are adapted to be released from one another, or to be connected to one another, by means of a rotational movement about an axis of rotation.
