Abstract
A power tool ensemble includes at least a power head, a first shaft coupler, and a second shaft coupler, for use with tool heads of landscaping tools. The power head includes a motor and a power shaft mechanically coupled to the motor. Each shaft coupler includes a power shaft connecter for connecting to the power shaft, and a shaft-specific connecter for connecting to tool shafts of the tool heads. In each shaft coupler, the power shaft connecter is mechanically coupled to the shaft-specific connecter. The shaft-specific connecter in the first shaft coupler has a different tool shaft configuration from the shaft-specific connecter in the second shaft coupler.
Claims20
A power tool ensemble, comprising:
- a power head, including:
- a motor;
- and
- a power shaft mechanically coupled to the motor;
- a first shaft coupler, including:
- a first power shaft connecter configured to be capable of being mechanically coupled to the power shaft;
- a first shaft-specific connecter having a first tool shaft configuration configured to be capable of being mechanically coupled to a first tool shaft of a first tool head, the first shaft-specific connecter being coupled to the first power shaft connecter;
- and
- a first coupler housing around the first power shaft connecter and the first shaft-specific connecter, wherein the first power shaft connecter and the first shaft-specific connecter are rotationally supported in the first coupler housing;
- and
- a second shaft coupler, including:
- a second power shaft connecter configured to be capable of being mechanically coupled to the power shaft;
- a second shaft-specific connecter having a second tool shaft configuration configured to be capable of being mechanically coupled to a second tool shaft of a second tool head, the second shaft-specific connecter being coupled to the second power shaft connecter;
- and
- a second coupler housing around the second power shaft connecter and the second shaft-specific connecter, wherein the second power shaft connecter and the second shaft-specific connecter are rotationally supported in the second coupler housing;
- wherein the second tool shaft configuration is different from the first tool shaft configuration, the first shaft coupler is separate from the power head and the first tool head, and the second shaft coupler is separate from the power head and the second tool head.
A power tool ensemble, comprising:
- a power head configured to provide rotational mechanical power;
- a first shaft coupler configured to transfer the rotational mechanical power to a first tool head, the first shaft coupler having a first coupler housing that is configured to be capable of being clamped on the tool head, wherein first shaft connecters of the first shaft coupler, which are configured to transfer the rotational mechanical power, are rotationally supported in the first coupler housing;
- and
- a second shaft coupler configured to transfer the rotational mechanical power to a second tool head, the second shaft coupler having a second coupler housing that is configured to be capable of being clamped on the second tool head, wherein second shaft connecters of the second shaft coupler, which are configured to transfer the rotational mechanical power, are rotationally supported in the second coupler housing;
- wherein the first shaft coupler is free of a mechanism to transfer the rotational mechanical power to the second tool head, and the second shaft coupler is free of a mechanism to transfer the rotational mechanical power to the first tool head.
